DETAILED DESCRIPTION

[0041] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0042] A cooling fan is a refrigeration device that mainly reduces the air temperature by absorbing heat through water evaporation, and uses a fan to blow out the lower temperature air to achieve environmental cooling. Among them, a water tank is usually integrated in the cooling fan to store a certain amount of water for water evaporation. The water tank is usually detachably connected to the inside of the cooling fan, and the user needs to completely remove the water tank from the cooling fan to perform the water adding operation.

[0043] However, during the repeated water adding process, fasteners such as screws, bolts and clips need to be frequently operated, which may cause the fasteners of the water tank to wear out, affecting the service life of the water tank and the convenience of water adding.

[0044] Based on the above technical problems, an embodiment of the present invention is proposed. The embodiment of the present invention discloses a water tank device, which may include a base 1, a water tank body 2 and an elastic locking assembly 3. The base 1 is provided with a receiving cavity 101 with an opening facing one side, and a limiting groove 102 is provided at the bottom of the base 1. The water tank body 2 is located in the receiving cavity 101 and is rotatably connected with the base 1. Under the drive of an external force, the water tank body 2 rotates from the receiving cavity 101 to the outside of the base 1. The elastic locking assembly 3 is installed on the water tank body 2 and extends into the limiting groove 102 to lock the relative position of the base 1 and the water tank body 2. When the elastic locking assembly 3 is pulled up, the elastic locking assembly 3 moves to the outside of the limiting groove 102, and the relative position of the base 1 and the water tank body 2 is unlocked. Therefore, when water needs to be added, the elastic lock assembly 3 is pulled up to release the lock of the relative position of the base 1 and the water tank body 2, and the water tank body 2 is rotated to move the water tank body 2 out of the accommodating cavity 101 to add water. After the water is added, the elastic lock assembly 3 is pulled up, the water tank body 2 is rotated into the accommodating cavity 101, and the elastic lock assembly 3 is released to fix the water tank body 2. In this way, on the basis of ensuring the service life of the water tank device, the convenience of adding water to the water tank device can also be improved.

[0045] Reference Figure 1-9, an embodiment of the present invention provides a water tank device, which may include a base 1, a water tank body 2, and an elastic locking assembly 3. The base 1 is provided with a receiving cavity 101 with an opening facing one side, and a limiting groove 102 is provided at the bottom of the base 1. The water tank body 2 is located in the receiving cavity 101 and is rotatably connected with the base 1. Under the drive of an external force, the water tank body 2 rotates from the receiving cavity 101 to the outside of the base 1. The elastic locking assembly 3 is installed on the water tank body 2 and extends into the limiting groove 102 to lock the relative position of the base 1 and the water tank body 2. When the elastic locking assembly 3 is pulled up, the elastic locking assembly 3 moves to the outside of the limiting groove 102, and the relative position of the base 1 and the water tank body 2 is unlocked.

[0046] In an embodiment of the present invention, the water tank device may include a base 1, a water tank body 2, and an elastic locking assembly 3. The base 1 is provided with a receiving cavity 101 with an opening facing one side, the receiving cavity 101 is used to receive the water tank body 2, and the opening is used for the water tank body 2 to move horizontally into the receiving cavity 101. A rotational connection is formed between the water tank body 2 and the base 1, and the central axis of the rotating shaft between the water tank body 2 and the base 1 is vertically arranged. Thus, an external force can be applied from the side end of the water tank body 2 away from the base 1. Under the drive of the external force, the water tank body 2 can be horizontally rotated to the outside of the receiving cavity 101 along the radial direction of the rotating shaft, so as to remove the water tank body 2 from the base 1. At this time, water can be added to the inside of the water tank body 2 from the top opening of the water tank body 2.

[0047] The elastic locking component 3 is installed on the water tank body 2. For example, the elastic locking component 3 can be located on the side surface of the water tank body 2 in an area close to the bottom of the base 1. The base 1 is provided with a limiting groove 102. The bottom of the elastic locking component 3 can move up and down in the vertical direction. When the water tank is rotated to the accommodating cavity 101 and is in clearance fit with the base 1, the elastic locking component 3 can extend into the limiting groove 102. The horizontal displacement of the water tank body 2 is limited by the abutment between the elastic locking component 3 and the limiting groove 102, thereby locking the relative position between the base 1 and the water tank body 2.

[0048] When the water tank device is filled with water, the elastic lock assembly 3 can be pulled up to lift the bottom of the elastic lock assembly 3 to move outside the limiting groove 102, thereby releasing the relative position lock between the base 1 and the water tank body 2. Then, the elastic lock assembly 3 is pulled horizontally to drive the water tank body 2 fixed with the elastic lock assembly 3 to rotate horizontally, and the elastic lock assembly 3 is released after the water tank body 2 is rotated outside the accommodating cavity 101, and the water tank body 2 is filled with water. After the water is added, the elastic locking component 3 is pulled up again, so that the elastic locking component 3 moves upward along the water tank body 2, thereby lifting the bottom of the elastic locking component 3, and pressing the elastic locking component 3, so that the water tank body 2 rotates into the accommodating cavity 101. After the water tank body 2 rotates into place, the elastic locking component 3 is released. Through the elastic recovery effect of the elastic locking component 3, the elastic locking component 3 moves downward along the water tank body 2 and forms abutment with the limiting groove 102.

[0049] Therefore, during the water-adding process, there is no need to frequently disassemble and assemble threaded components and snap fasteners, which can avoid wear of fasteners (e.g., long-term wear causing screw thread stripping, threaded hole damage, snap fastener failure, etc.) and reduce the service life of the water tank device. In addition, during the water-adding process, the user only needs to operate the elastic lock assembly 3, which greatly improves the convenience of water-adding of the water tank device. In addition, the rotational cooperation between the water tank body 2 and the base 1 can improve the convenience of disassembly and assembly of the water tank body 2, thereby further improving the convenience of user operation, and realizing the effects of flipping the cooling fan to add water, quick disassembly and assembly for cleaning, etc.

[0050] An optional embodiment of the invention, referring to Figure 2-7 As shown, the water tank body 2 is provided with a first slot 201 extending in the vertical direction, and the elastic lock assembly 3 may include a lock housing 31, an elastic telescopic unit 32, and a first clip 33. The lock housing 31 is slidably connected to the side of the water tank body 2, so that the lock housing 31 moves up and down along the water tank body 2. One end of the elastic telescopic unit 32 is fixedly connected to the lock housing 31, and the other end is in contact with the water tank body 2. The first clip 33 is arranged on the lock housing 31, and is clipped with the first slot 201. Among them, when the elastic telescopic unit 32 is in the absence of external force and under the deformation of the elastic telescopic unit 32, the first clip 33 abuts against the bottom of the first slot 201 to allow the lock shell 31 to extend into the limiting slot 102. When the lock shell 31 is pulled up to compress the elastic telescopic unit 32, the first clip 33 abuts against the top of the first slot 201 to lift the lock shell 31 out of the limiting slot 102.

[0051] In the embodiment of the present invention, a first slot 201 extending in the vertical direction is provided on the side end surface of the water tank body 2, and the elastic lock assembly 3 may include a lock housing 31, an elastic expansion unit 32, and a first lock 33. The lock housing 31 is slidably connected to the side end surface of the water tank body 2, so that the lock housing 31 can slide up and down along the water tank body 2 to achieve the lifting movement of the bottom of the elastic lock assembly 3.

[0052] The elastic telescopic unit 32 has elastic deformation performance, and can perform telescopic movement in the vertical direction under the action of external force. For example, one end of the elastic telescopic unit 32 is fixedly connected to the lock shell 31, and the other end of the elastic telescopic unit 32 is in contact with the water tank body 2. When the lock shell 31 is pushed to slide upward and an abutting force is applied to the elastic telescopic unit 32, the elastic telescopic unit 32 will perform a compression movement close to the abutment point of the water tank body 2 under the action of the abutting force, so that the bottom of the lock shell 31 can be lifted from the limit groove 102 to the outside of the limit groove 102, thereby releasing the relative position lock between the base 1 and the water tank body 2. When there is no driving force on the lock shell 31, the elastic telescopic unit 32 will retract and recover. At this time, the elastic telescopic unit 32 gradually extends and drives the lock shell 31 fixed to the elastic telescopic unit 32 to slide downward, so that the bottom of the lock shell 31 drops from outside the limit groove 102 to inside the limit groove 102, thereby realizing the position locking between the base 1 and the water tank body 2.

[0053] The first snap 33 is arranged on the lock shell 31 and is snapped with the first slot 201. The first slot 201 has a certain height in the vertical direction, so that a certain lifting stroke can be provided to the first snap 33 in the first slot 201. In one example, when there is no external force acting on the elastic telescopic unit 32 (that is, when there is no upward driving force acting on the lock shell 31), the elastic telescopic unit 32 will retract and recover. At this time, the elastic telescopic unit 32 gradually extends and drives the lock shell 31 fixed with the elastic telescopic unit 32 to slide downward, and the first snap 33 arranged on the lock shell 31 slides downward synchronously. The first snap 33 slides downward from the top of the first slot 201 to the bottom of the first slot 201, and the position of the lock shell 31 can be limited by the bottom of the first slot 201 abutting against the first snap 33. Furthermore, the bottom of the locking shell 31 is made to drop from outside the limiting groove 102 to inside the limiting groove 102 , thereby realizing position locking between the base 1 and the water tank body 2 .

[0054] In other embodiments, when the lock shell 31 is pushed to slide upward and abutting force is applied to the elastic telescopic unit 32, the elastic telescopic unit 32 will perform a compression movement close to the abutment point of the water tank body 2 under the action of the abutting force, so that the bottom of the lock shell 31 can be lifted from the inside of the limiting groove 102 to the outside of the limiting groove 102, and the relative position between the base 1 and the water tank body 2 is unlocked. At this time, the first buckle 33 provided on the lock shell 31 slides upward synchronously. The first buckle 33 slides upward from the bottom of the first slot 201 to the top of the first slot 201, and when the top of the first slot 201 abuts against the first buckle 33, the lock shell 31 is restricted from sliding further upward. Therefore, the first buckle 33 and the first slide groove 202 cooperate with each other to limit the sliding stroke of the lock shell 31.

[0055] An optional embodiment of the invention, referring to Figure 2 and Figure 4 As shown, the top of the lock housing 31 is provided with an elastic accommodating groove 3101, and the elastic telescopic unit 32 may include a mounting column 321 and a return spring 322, wherein the mounting column 321 is fixed in the elastic accommodating groove 3101. The return spring 322 is sleeved on the mounting column 321, and one end of the return spring 322 abuts against the water tank body 2.

[0056] In the embodiment of the present invention, an elastic accommodating groove 3101 is further provided at the top of the lock housing 31, and the elastic accommodating groove 3101 is used to accommodate the elastic telescopic unit 32. In order to improve the sliding stability of the lock housing 31, the number of the elastic telescopic units 32 can be at least two, and at least two elastic telescopic units 32 can be distributed at intervals at the top of the lock housing 31. Those skilled in the art can also determine the number of the elastic telescopic units 32 according to actual design requirements, for example, it can be 2, 3, 4, etc., and no excessive restrictions are made here.

[0057] The elastic telescopic unit 32 may include a mounting post 321 and a return spring 322. The mounting post 321 is fixed in the elastic accommodating groove 3101. For example, the mounting post 321 and the lock shell 31 may be an integrated structure. For another example, the mounting post 321 may be fixed with the lock shell 31 by snapping. The return spring 322 is sleeved on the mounting post 321, and one end of the return spring 322 abuts against the water tank body 2. The other end of the return spring 322 may be interference fit with the bottom of the mounting post 321, thereby achieving a fixed connection of the return spring 322. In another example, the other end of the return spring 322 may have a hook, so that it is hung on the lock shell 31 through the hook.

[0058] When the lock shell 31 is pushed to slide upward and abutting force is applied to the elastic telescopic unit 32, the reset spring 322 will perform a vertical upward compression movement under the action of the abutting force. The setting of the mounting column 321 can also prevent the reset spring 322 from undergoing radial torsion, thereby improving the movement stability of the reset spring 322. In addition, the bottom of the lock shell 31 is lifted from the inside of the limiting groove 102 to the outside of the limiting groove 102, thereby releasing the lock of the relative position between the base 1 and the water tank body 2. At this time, the first buckle 33 provided on the lock shell 31 slides upward synchronously. The first buckle 33 slides upward from the bottom of the first slot 201 to the top of the first slot 201, and when the top of the first slot 201 abuts against the first buckle 33, the lock shell 31 is restricted from sliding further upward. Therefore, the first buckle 33 and the first sliding groove 202 cooperate with each other to limit the sliding stroke of the lock housing 31 and the retraction length of the return spring 322 .

[0059] When the lock housing 31 is not acted upon by a driving force, the reset spring 322 will retract and recover. At this time, the reset spring 322 gradually extends and drives the lock housing 31 connected to the reset spring 322 to slide downward, so that the bottom of the lock housing 31 drops from the outside of the limiting groove 102 to the inside of the limiting groove 102. At this time, the first clip 33 slides downward from the top of the first clip 201 to the bottom of the first clip 201, and the bottom of the first clip 201 abuts against the first clip 33, so that the position of the lock housing 31 can be limited. In addition, the bottom of the lock housing 31 drops from the outside of the limiting groove 102 to the inside of the limiting groove 102, so as to achieve position locking between the base 1 and the water tank body 2.

[0060] An optional embodiment of the invention, referring to Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, a limiting boss 34 is provided at the bottom of the lock housing 31 , and when the first buckle 33 abuts against the bottom of the first slot 201 , the limiting boss 34 extends into the limiting slot 102 .

[0061] In the embodiment of the present invention, a limiting boss 34 is provided at the bottom of the lock shell 31. For example, the limiting boss 34 can be provided to extend downward along the bottom of the lock shell 31. The limiting boss 34 is used to form an abutment with the limiting groove 102. For example, when the bottom of the first card slot 201 forms an abutment with the first card buckle 33, the limiting boss 34 extends into the limiting groove 102 and forms an abutment with the groove wall of the limiting groove 102, so that the relative position between the water tank body 2 and the base 1 can be locked. For example, the limiting boss 34 and the abutment surface of the limiting groove 102 are matched in shape, so that the abutment stability between the limiting boss 34 and the limiting groove 102 can be improved by expanding the abutment area between the limiting boss 34 and the limiting groove 102.

[0062] In some preferred embodiments, the limiting boss 34 and the lock housing 31 are an integrated structure, thereby improving the connection firmness between the limiting boss 34 and the lock housing 31 and reducing the production process and production cost of the elastic lock assembly 3.

[0063] In some other optional implementations, refer to Figure 2 and Figure 6 As shown, a guide groove 104 is also provided on the bottom of the base 1, and the number of the guide grooves 104 is consistent with the number of the limiting bosses 34, wherein the guide groove 104 can be spatially connected with the limiting groove 102, and the bottom of the guide groove 104 is higher than the height of the limiting groove 102, and the inner bottom height of the base 1 is higher than the bottom height of the guide groove 104. Thus, the limiting boss 34 can slide from the guide groove 104, thereby shortening the sliding stroke of the lock housing 31, or shortening the deformation length of the return spring 322, and the limiting boss 34 is lifted to the bottom of the guide groove 104, so as to rotate the water tank body 2. Compared with lifting the limiting boss 34 to the inner bottom of the base 1 and then rotating the water tank body 2, the user moves the lock housing 31 in a shorter stroke, which can further improve the user experience.

[0064] An optional embodiment of the invention, referring to Figure 2 , Figure 4 as well as Figure 5As shown, the elastic locking assembly 3 further includes a locking flange 35 , and the locking flange 35 is extended outwardly from the end surface of the locking shell 31 away from the water tank body 2 .

[0065] In the embodiment of the present invention, the elastic lock assembly 3 may further include a lock flange 35, and the lock flange 35 may be located on the end surface of the lock shell 31 away from the water tank body 2. For example, the lock flange 35 is fixedly connected to the lock shell 31. Alternatively, the lock flange 35 and the lock shell 31 are an integrated structure. The lock flange 35 may be located in the middle area of ​​the lock shell 31 and extend outwardly for a certain length in the horizontal direction of the lock shell 31. Therefore, the lock flange 35 can be regarded as a handle for the user to pull the lock shell 31.

[0066] When it is necessary to add water to the water tank body 2, the user grasps the lock flange 35 and pushes the lock shell 31 to slide upward. When the abutting force is applied to the elastic telescopic unit 32, the reset spring 322 will perform a vertical upward compression movement under the action of the abutting force. In addition, the bottom of the lock shell 31 is lifted from the inside of the limiting groove 102 to the outside of the limiting groove 102, releasing the lock of the relative position between the base 1 and the water tank body 2. At this time, the first buckle 33 provided on the lock shell 31 slides upward synchronously. The first buckle 33 slides upward from the bottom of the first slot 201 to the top of the first slot 201, and when the top of the first slot 201 abuts against the first buckle 33, the lock shell 31 is restricted from sliding further upward. Then pull the locking flange 35 outward to drive the water tank body 2 to rotate outside the accommodating cavity 101, and the water tank body 2 is moved out of the base 1. At this time, water can be added to the inside of the water tank body 2 through the top opening of the water tank body 2.

[0067] After the water is added, the user grasps the lock flange 35 and pushes the lock shell 31 to slide upward. When the abutting force is applied to the elastic telescopic unit 32, the reset spring 322 will perform a vertical upward compression movement under the action of the abutting force. At this time, the limiting boss 34 is in a lifted state. The lock flange 35 is pressed in the direction close to the accommodating cavity 101, and the lock shell 31 is driven to rotate horizontally into the accommodating cavity 101. When the user releases the lock flange 35, when there is no driving force on the lock shell 31, the reset spring 322 will retract and recover. At this time, the reset spring 322 gradually extends and drives the lock shell 31 connected to the reset spring 322 to slide downward, so that the bottom of the lock shell 31 drops from the outside of the limiting groove 102 to the inside of the limiting groove 102. At this time, the first buckle 33 slides downward from the top of the first slot 201 to the bottom of the first slot 201, and the bottom of the first slot 201 abuts against the first buckle 33, so that the position of the lock housing 31 can be limited. In addition, the bottom of the lock housing 31 is dropped from the outside of the limiting groove 102 to the inside of the limiting groove 102, so that the position locking between the base 1 and the water tank body 2 is achieved.

[0068] Therefore, during the water filling process, there is no need to frequently disassemble and assemble the threaded components and the buckle components, which can avoid the wear of the fasteners (such as long-term wear causing screw thread stripping, thread hole damage, buckle failure, etc.) and reduce the service life of the water tank device. In addition, during the water filling process, the user only needs to operate the elastic lock buckle assembly 3, which greatly improves the convenience of water filling of the water tank device.

[0069] An optional embodiment of the invention, referring to Figure 4 , Figure 6 as well as Figure 7 As shown, a slide groove 202 in a vertical direction is provided on the side of the water tank body 2 , and a guide rail 4 is provided on the side of the lock shell 31 , and the guide rail 4 is slidably connected to the slide groove 202 .

[0070] In the embodiment of the present invention, a vertical slide groove 202 is provided on the side of the water tank body 2, and a guide rail 4 is provided on the side of the lock housing 31 corresponding to the assembly area, so that when the lock housing 31 is assembled from the bottom of the water tank body 2 upward, the guide rail 4 is placed in the slide groove 202 to achieve a sliding connection between the guide rail 4 and the slide groove 202. In some preferred embodiments, the guide rail 4 and the lock housing 31 can be an integrated structure.

[0071] An optional embodiment of the invention, referring to Figure 2 and Figure 8As shown, a movable hole 103 is opened on the base 1, and the water tank device also includes a latch 5, which is fixedly connected to the water tank body 2, wherein the latch 5 is embedded in the movable hole 103 so that the base 1 and the water tank body 2 form a rotational connection.

[0072] In the embodiment of the present invention, a movable hole 103 is provided on the base 1, and the water tank device may further include a latch 5, and the latch 5 may be fixedly connected to the water tank body 2. When the water tank body 2 is connected to the base 1, the water tank body 2 may be placed in the accommodating cavity 101, and the latch 5 may be inserted into the movable hole 103 from top to bottom, so as to form a clearance fit between the latch 5 and the movable hole 103. Thus, the water tank body 2 uses the latch 5 as a rotation axis, and when the water tank body 2 is pulled, the water tank body 2 may be driven to rotate outside the accommodating cavity 101. The matching mode of the latch 5 and the movable hole 103 may improve the convenience of disassembly and assembly of the water tank body 2, thereby further improving the convenience of user operation, and realizing the effects of flipping and adding water to the cold fan, and quick disassembly and assembly for cleaning.

[0073] An optional embodiment of the invention, referring to Figure 1 , Figure 2 as well as Fig. 9 As shown, the water tank device further includes a cover plate 6 , which is disposed between the water tank body 2 and the elastic locking assembly 3 and is fixedly connected to the water tank body 2 to close the elastic locking assembly 3 .

[0074] In the embodiment of the present invention, the water tank device may further include a cover plate 6, which is disposed between the water tank body 2 and the elastic lock assembly 3 to protect the components on the elastic lock assembly 3, for example, to close the movable space between the reset spring 322 and the water tank body 2. On the other hand, the cover plate 6 is fixedly connected to the water tank body 2, and may also cover the outer end surface of the water tank body 2, and play the role of installing the water tank body 2.

[0075] In some embodiments, a through groove is further provided on the portion of the cover plate 6 corresponding to the elastic locking assembly 3, so that the locking flange 35 extends to the outer end surface of the cover plate 6 away from the water tank body 2, that is, extends outside the through groove, thereby facilitating the user to grasp the locking flange 35 and operate the elastic locking assembly 3.

[0076] An optional embodiment of the invention, referring to Figure 2 , Figure 6 , Figure 7 as well as Fig. 9As shown, the water tank body 2 and the cover plate 6 are clamped and fixed.

[0077] In the embodiment of the present invention, the water tank body 2 is provided with a first buckle position 9, and the cover plate 6 is provided with a second buckle position 10 in the assembly area corresponding to the first buckle position 9, so that the water tank body 2 and the cover plate 6 can be fixed by a snap connection through the cooperation of the first buckle position 9 and the second buckle position 10. For example, the first buckle position 9 and the water tank body 2 are an integrated structure. For another example, the second buckle position 10 and the cover plate 6 are an integrated structure.

[0078] In some preferred embodiments, a second buckle and a second slot may be provided at the connection between the water tank body 2 and the cover plate 6 to form a multi-point snap connection, thereby improving the connection firmness between the water tank body 2 and the cover plate 6.

[0079] An optional embodiment of the invention, referring to Figure 2 , Figure 3 , Figure 6 as well as Figure 8 As shown, the outer side of the water tank body 2 is provided with a load-bearing rib 7, the inner side of the base 1 is provided with a load-bearing lug 8, and the load-bearing rib 7 is located above the load-bearing lug 8 and forms pressure contact with the load-bearing lug 8.

[0080] In the embodiment of the present invention, a bearing rib 7 is provided on the outer side of the water tank body 2, and a bearing lug 8 is provided on the inner side of the base 1. In order to improve the rotational stability of the water tank body 2, the bearing rib 7 is located above the bearing lug 8 and forms a pressure contact with the bearing lug 8, so that during the rotation of the water tank body 2, the bearing lug 8 and the bearing rib 7 can be contacted and matched to reduce the axial load of the latch 5, thereby extending the service life of the latch 5.

[0081] As some preferred implementations, the load-bearing ribs 7 and the water tank body 2 are an integrated structure, and the load-bearing ears 8 and the base 1 are an integrated structure.

[0082] In an optional embodiment of the invention, the load-bearing ribs 7 are arranged around the water tank body 2 in a horizontal direction.

[0083] In the embodiment of the present invention, the bearing ribs 7 are arranged around the water tank body 2 in the horizontal direction, which can be understood as the bearing ribs 7 can surround the outer end surface of the water tank body 2 in the horizontal direction of the water tank body 2. For example, in order to facilitate the positioning of the water tank body 2 by the base 1 and the rotation of the water tank body 2, the horizontal cross-section of the end surface area of ​​the water tank body 2 away from the latch 5 is less than half of a circle, and the bearing ribs 7 are arranged in this end surface area, which can ensure that the bearing ribs 7 always maintain surface contact with the bearing lugs 8 during the rotation of the water tank body 2.

[0084] In summary, an embodiment of the present invention discloses a water tank device, which may include a base 1, a water tank body 2, and an elastic locking assembly 3. The base 1 is provided with a receiving cavity 101 with an opening facing one side, and a limiting groove 102 is provided at the bottom of the base 1. The water tank body 2 is located in the receiving cavity 101 and is rotatably connected with the base 1. Under the drive of an external force, the water tank body 2 rotates from the receiving cavity 101 to the outside of the base 1. The elastic locking assembly 3 is installed on the water tank body 2 and extends into the limiting groove 102 to lock the relative position of the base 1 and the water tank body 2. When the elastic locking assembly 3 is pulled up, the elastic locking assembly 3 moves to the outside of the limiting groove 102, and the relative position of the base 1 and the water tank body 2 is unlocked. Therefore, when water needs to be added, the elastic lock assembly 3 is pulled up to release the lock of the relative position of the base 1 and the water tank body 2, and the water tank body 2 is rotated to move the water tank body 2 out of the accommodating cavity 101 to add water. After the water is added, the elastic lock assembly 3 is pulled up, the water tank body 2 is rotated into the accommodating cavity 101, and the elastic lock assembly 3 is released to fix the water tank body 2. In this way, on the basis of ensuring the service life of the water tank device, the convenience of adding water to the water tank device can also be improved.

[0085] An embodiment of the present invention further discloses a cooling fan, which includes a water tank device as described in any one of the above-mentioned embodiments of the invention.

[0086] In the embodiment of the present invention, the cooling fan is a refrigeration device, which mainly reduces the air temperature by absorbing heat through water evaporation, and uses a fan to blow out the air with a lower temperature to achieve environmental cooling. Among them, the cooling fan is integrated with the above-mentioned water tank device to store a certain volume of water for cooling.

[0087] The water tank device may include a base 1, a water tank body 2 and an elastic locking assembly 3. The base 1 is provided with a receiving cavity 101 with an opening facing one side, the receiving cavity 101 is used to receive the water tank body 2, and the opening is used for the water tank body 2 to move horizontally into the receiving cavity 101. A rotational connection is formed between the water tank body 2 and the base 1, and the central axis of the rotating shaft between the water tank body 2 and the base 1 is vertically arranged. Thus, an external force can be applied from the side end of the water tank body 2 away from the base 1. Under the drive of the external force, the water tank body 2 can be horizontally rotated to the outside of the receiving cavity 101 along the radial direction of the rotating shaft, thereby removing the water tank body 2 from the base 1. At this time, water can be added to the inside of the water tank body 2 from the top opening of the water tank body 2.

[0088] The elastic locking component 3 is installed on the water tank body 2. For example, the elastic locking component 3 can be located on the side surface of the water tank body 2 in an area close to the bottom of the base 1. The base 1 is provided with a limiting groove 102. The bottom of the elastic locking component 3 can move up and down in the vertical direction. When the water tank is rotated to the accommodating cavity 101 and is in clearance fit with the base 1, the elastic locking component 3 can extend into the limiting groove 102. The horizontal displacement of the water tank body 2 is limited by the abutment between the elastic locking component 3 and the limiting groove 102, thereby locking the relative position between the base 1 and the water tank body 2.

[0089] When the water tank device is filled with water, the elastic lock assembly 3 can be pulled up to lift the bottom of the elastic lock assembly 3 to move outside the limiting groove 102, thereby releasing the relative position lock between the base 1 and the water tank body 2. Then, the elastic lock assembly 3 is pulled horizontally to drive the water tank body 2 fixed with the elastic lock assembly 3 to rotate horizontally, and the elastic lock assembly 3 is released after the water tank body 2 is rotated outside the accommodating cavity 101, and the water tank body 2 is filled with water. After the water is added, the elastic locking component 3 is pulled up again, so that the elastic locking component 3 moves upward along the water tank body 2, thereby lifting the bottom of the elastic locking component 3, and pressing the elastic locking component 3, so that the water tank body 2 rotates into the accommodating cavity 101. After the water tank body 2 rotates into place, the elastic locking component 3 is released. Through the elastic recovery effect of the elastic locking component 3, the elastic locking component 3 moves downward along the water tank body 2 and forms abutment with the limiting groove 102.

[0090] Therefore, during the water filling process, there is no need to frequently disassemble and assemble the threaded components and the buckle components, which can avoid the wear of the fasteners (such as long-term wear causing screw thread stripping, thread hole damage, buckle failure, etc.) and reduce the service life of the water tank device. In addition, during the water filling process, the user only needs to operate the elastic lock buckle assembly 3, which greatly improves the convenience of water filling of the water tank device.

[0091] In addition, the rotational cooperation between the water tank body 2 and the base 1 can improve the convenience of disassembly and assembly of the water tank body 2, thereby further improving the convenience of user operation, and realizing the effects of flipping the cooling fan to add water, quick disassembly and assembly for cleaning, etc.

[0092] In summary, an embodiment of the present invention further discloses a cooling fan, which may include a base 1, a water tank body 2, and an elastic locking assembly 3. The base 1 is provided with a receiving cavity 101 with an opening facing one side, and a limiting groove 102 is provided at the bottom of the base 1. The water tank body 2 is located in the receiving cavity 101 and is rotatably connected with the base 1. Under the driving force of an external force, the water tank body 2 is rotated from the receiving cavity 101 to the outside of the base 1. The elastic locking assembly 3 is installed on the water tank body 2 and extends into the limiting groove 102 to lock the relative position of the base 1 and the water tank body 2. When the elastic locking assembly 3 is pulled up, the elastic locking assembly 3 moves to the outside of the limiting groove 102, and the relative position of the base 1 and the water tank body 2 is unlocked. Therefore, when water needs to be added, the elastic locking assembly 3 is pulled up to unlock the relative positions of the base 1 and the water tank body 2, and the water tank body 2 is rotated to move the water tank body 2 out of the accommodating cavity 101 to add water. After the water is added, the elastic locking assembly 3 is pulled up, the water tank body 2 is rotated into the accommodating cavity 101, and the elastic locking assembly 3 is released to fix the water tank body 2. In this way, on the basis of ensuring the service life of the cooling fan, the convenience of adding water to the cooling fan can also be improved.
