Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1 and 2, in one embodiment, there is provided a tank mechanism 10 including:

the water tank comprises a water tank body 11, wherein a water storage space 111 is arranged in the water tank body 11, and a positioning piece 112 is arranged on the wall surface of the water storage space 111;

the water pump fixing assembly 12 comprises a fitting member 121 and a fixing member 122, the fixing member 122 is used for fixing the water pump 20, the fitting member 121 is detachably connected with the positioning member 112 in a screwing mode, and the fixing member 122 is connected with the fitting member 121 so that the fixing member 122 can rotate along with the fitting member 121.

In other words, the fixing member 122, the water pump 20 fixed to the fixing member 122, and the engaging member 121 are an integral component that moves synchronously when screwed. Specifically, the fixing element 122 and the mating element 121 may be fixedly connected together, for example, integrally connected together. Or the fixing member 122 and the fitting member 121 are detachably connected, but when the fitting member 121 is screwed with respect to the positioning member 112, the fixing member 122 needs to be able to rotate together with the fitting member 121.

The above-mentioned solution provides a water tank mechanism 10, the positioning member 112 is disposed on the wall surface of the water storage space 111, the mating member 121 of the water pump fixing assembly 12 is detachably connected with the positioning member 112 by screwing, and the fixing member 122 and the water pump 20 on the fixing member 122 will rotate along with the screwing process. Therefore, the water pump 20 can be fixed in the water storage space 111 in the process of pumping water, when the water tank body 11 needs to be cleaned, the water pump 20 can rotate along with the water pump fixing component 12 to be detached from the water storage space 111, and the operation is simple and convenient. The mounting and dismounting states of the water pump 20 in the water tank body 11 can be switched by only one screwing action.

Specifically, as shown in fig. 8 and 9, in one embodiment, the positioning member 112 is threadedly engaged with the engaging member 121. The connection state between the positioning member 112 and the fitting member 121 is changed by integrally rotating the water pump fixing assembly 12. Specifically, as shown in fig. 8 and 9, the positioning element 112 is a stud 13 having an external thread, and the fitting element 121 is provided with a thread groove matching with the stud 13. Or, in another embodiment, a thread groove is formed on the wall surface of the water storage space 111, and an external thread matching with the thread groove is formed on the water pump fixing assembly 12.

Optionally, in another embodiment, as shown in fig. 2, the positioning element 112 and the mating element 121 are detachably connected by a screw-type connection.

Specifically, as shown in fig. 2 to 7, in an embodiment, the positioning element 112 includes a first supporting portion 1121 and a latching portion 1122, the first supporting portion 1121 is connected to a wall surface of the water storage space 111, the latching portion 1122 is connected to the first supporting portion 1121, and the latching portion 1122 is suspended outside the first supporting portion 1121 along a first direction, where the first direction intersects with a rotation axis of the mating element 121 when being screwed with respect to the positioning element 112. In other words, the first direction is not parallel to the rotation axis of the mating member 121 when screwed with respect to the positioning member 112.

Specifically, when the positioning member 112 is disposed on the bottom wall of the water storage space 111, the first supporting portion 1121 is connected to the bottom wall of the water storage space 111.

The fitting element 121 includes a second support portion 1211 and a limiting portion 1212, the second support portion 1211 is connected to the fixing element 122, the limiting portion 1212 is suspended on the second support portion 1211, a limiting groove is formed between the limiting portion 1212 and the fixing element 122 at an interval, and the fastening portion 1122 can be screwed into the limiting groove.

As shown in fig. 7, when the water pump fixing assembly 12 is installed in the water storage space 111, the fastening portion 1122 is screwed into the limiting groove, and the fastening portion 1122 is located on one side of the limiting portion 1212 close to the fixing member 122 to limit the fastening portion 1122 in the limiting groove.

When the water pump 20 needs to be disassembled, the water pump fixing assembly 12 needs to be rotated relative to the positioning member 112 first, so that the latching portion 1122 exits from the limiting groove, the limiting portion 1212 is disengaged from the limiting position of the latching portion 1122, and then the water pump 20 and the water pump fixing assembly 12 can be taken out from the water storage space 111 together.

More specifically, in an embodiment, as shown in fig. 2 and fig. 3, the first supporting portion 1121 has a circular ring structure, a rotation axis of the mating member 121 when screwing with respect to the positioning member 112 is a central axis of the first supporting portion 1121, and the first direction is parallel to a normal direction of the mating member 121 with respect to a screwing direction of the positioning member 112.

The fastening portion 1122 is suspended outside the first supporting portion 1121 along a normal direction of the mating member 121 with respect to the screwing direction of the positioning member 112, and when the water pump fixing assembly 12 rotates with respect to the first supporting portion 1121, a relative position between the fastening portion 1122 and the limiting groove changes, so that changes of two states of clamping and disengaging are realized.

Further, as shown in fig. 4 and 5, the fitting member 121 is plural, and the fitting members 121 are sequentially arranged along the circumferential direction of the first supporting portion 1121. And each of the limiting portions 1212 abuts against the first supporting portion 1121. In the screwing process, the limiting portion 1212 abuts against the first supporting portion 1121, so that a rotation axis of the water pump fixing assembly 12 when rotating is always a central axis of the first supporting portion 1121.

Specifically, the stopper 1212 may abut against an outer circumferential surface of the first support portion 1121 or an inner circumferential surface of the first support portion 1121. In other words, the position-limiting portion 1212 may be located within the space surrounded by the first supporting portion 1121 or located outside the space surrounded by the first supporting portion 1121.

When the limiting portion 1212 is located in the space surrounded by the first supporting portion 1121, the locking portion 1122 is also located in the space surrounded by the first supporting portion 1121. When the limiting portion 1212 is located outside the space surrounded by the first supporting portion 1121, the locking portion 1122 is located outside the space surrounded by the first supporting portion 1121.

As shown in fig. 4 and 5, each of the limiting grooves has a first opening facing the first support portion 1121 and a second opening facing in parallel with a tangential direction of the screwing direction. The buckling part 1122 can be rotated into the limiting groove from the second opening, part of the buckling part 1122 is located in the limiting groove, and the other part of the buckling part 1122 penetrates through the first opening to be connected with the first supporting part 1121. The first opening provides a space for the locking portion 1122 to get out of when screwing.

More specifically, as shown in fig. 2 to 5, in an embodiment, the number of the buckling portions 1122 is multiple, and the multiple buckling portions 1122 are uniformly spaced along the circumferential direction of the first supporting portion 1121. Each of the locking portions 1122 may be screwed into the corresponding limiting groove, specifically, in some embodiments, one limiting groove may accommodate a plurality of locking portions 1122, and in other embodiments, one limiting groove may accommodate only one locking portion 1122.

Specifically, as shown in fig. 2, each of the locking portions 1122 is located outside a space surrounded by the first supporting portion 1121. Each of the locking portions 1122 is connected to an outer peripheral surface of the first support portion 1121.

Further specifically, the fitting members 121 may be sequentially arranged at intervals in the circumferential direction of the first support portion 1121. The gap between two adjacent spaced mating members 121 can accommodate the snap 1122.

Alternatively, in another embodiment, as shown in fig. 4 and 5, the second support portions 1211 are connected to each other to form a circular ring structure, and the position-limiting portions 1212 are arranged at regular intervals in the circumferential direction of the first support portion 1121. The spacing between the adjacent limiting portions 1212 forms a space 123 capable of accommodating the locking portion 1122, each of the second openings faces one of the space 123, and the limiting portions 1212 abut against the outer peripheral surface of the first supporting portion 1121.

During assembly, each of the receding spaces 123 is aligned with each of the buckling portions 1122, and the water pump fixing assembly 12 is inserted onto the positioning member 112, at this time, each of the limiting portions 1212 surrounds the first supporting portion 1121 along the circumferential direction of the first supporting portion 1121. Then, the water pump fixing assembly 12 is rotated, so that the fastening portion 1122 rotates from the retraction space 123 into the limiting groove.

The perspective of the cross-sectional views shown in fig. 4 and 5 is the perspective when viewed from below the tank body 11.

More specifically, as shown in fig. 2 and 3, in an embodiment, a position of the tank body 11 connected to the first support portion 1121 is an installation position, and both edges of the buckling portion 1122 are bent in a direction away from the installation position in a circumferential direction of the first support portion 1121. Therefore, the bent edge can prevent the fastening portion 1122 from directly colliding with the limiting portion 1212 in the front direction during screwing.

Further, as shown in fig. 3, an elastic pad 1123 is disposed on an end surface of the first supporting portion 1121, which faces away from the water tank body 11, and the elastic pad 1123 can be pressed between the first supporting portion 1121 and the fixing member 122, so that the fastening portion 1122 can be pressed in the limiting groove after the fastening portion 1122 is rotated into the limiting groove.

Further, in an embodiment, as shown in fig. 2, the positioning member 112 is disposed on a bottom wall of the water storage space 111. Alternatively, the positioning member 112 may be disposed on a side wall of the water storage space 111, which is not particularly limited herein.

Further, as shown in fig. 2, in one embodiment, the fixing member 122 has a fastening space 1221 for fixing the water pump 20, the fastening space 1221 has an opening, and the fitting member 121 is fixedly attached to an outer side surface of a bottom wall of the fastening space 1221.

A through hole 1222 is formed in a bottom wall of the fastening space 1221 at a position opposite to the mating member 121, so that whether the fastening portion 1122 is rotated into the limiting groove can be checked through the through hole 1222.

Further, in another embodiment, a fan is provided, comprising the above-described water tank mechanism 10.

The above scheme provides a fan, by adopting the water tank mechanism 10 described in any of the above embodiments, the water pump 20 can be fixed in the water tank body 11 when cold air needs to be blown, so as to provide power for water in the water tank body 11; when the water tank body 11 needs to be cleaned, the water pump 20 can be detached from the water tank body by detaching the water pump fixing component 12, so that the operation is simple and the cleaning is convenient.

Further, in one embodiment, the fan further includes a water pump 20, and the water pump 20 is detachably connected to the fixing member 122. After the water pump fixing unit 12 is removed from the tank body 11, the water pump 20 may be further removed from the water pump fixing unit 12, and then the water pump fixing unit 12 may be cleaned.
