DETAILED DESCRIPTION

[0041] Exemplary embodiments of the present application will be described herein below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it is understood that the present application can be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0042] ​​The cold fan is a refrigeration equipment, which mainly reduces the air temperature by water evaporation heat absorption, and blows out the air with lower temperature by the fan to realize the environment cooling. Among them, the water tank is usually integrated in the cold fan to store a certain capacity of water for water evaporation. Usually, the water tank is detachably connected in the inside of the cold fan, and the user needs to completely detach the water tank from the cold fan to add water.

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

[0044] Based on the above technical problems, the embodiments of the present application are proposed, and the water tank device is disclosed, which can include a base 1, a water tank body 2 and an elastic lock buckle assembly 3. The base 1 is provided with a containing cavity 101 with an opening facing one side, and the bottom of the base 1 is provided with a limiting groove 102. The water tank body 2 is located in the containing cavity 101 and is rotationally connected with the base 1. Under the driving of external force, the water tank body 2 is rotated from the containing cavity 101 to the outside of the base 1. The elastic lock buckle 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. In the case of pulling up the elastic lock buckle assembly 3, the elastic lock buckle assembly 3 moves out of the limiting groove 102, and the locking of the relative position of the base 1 and the water tank body 2 is released. Therefore, when water needs to be added, the elastic lock buckle assembly 3 is pulled up to release the locking of the relative position of the base 1 and the water tank body 2, and the water tank body 2 is rotated to move out of the containing cavity 101 to add water. After the water is added, the elastic lock buckle assembly 3 is pulled up to rotate the water tank body 2 into the containing cavity 101, and the elastic lock buckle assembly 3 is released to fix the water tank body 2. Thus, on the basis of ensuring the service life of the water tank device, the water adding convenience of the water tank device can also be improved.

[0045] Reference Figures 1-9The embodiment of the present application provides a water tank device, which can comprise a base 1, a water tank body 2 and an elastic lock assembly 3. The base 1 is provided with a containing cavity 101 with an opening facing one side, and the bottom of the base 1 is provided with a limiting groove 102. The water tank body 2 is located in the containing cavity 101 and rotationally connected with the base 1, and under the driving of external force, the water tank body 2 is rotated from the containing cavity 101 to the outside of the base 1. The elastic lock 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 lock assembly 3 is pulled upwards, the elastic lock assembly 3 moves out of the limiting groove 102 to release the locking of the relative position of the base 1 and the water tank body 2.

[0046] In the embodiment of the present application, the water tank device can comprise a base 1, a water tank body 2 and an elastic lock assembly 3. The base 1 is provided with a containing cavity 101 with an opening facing one side, the containing cavity 101 is used for containing the water tank body 2, and the opening is used for horizontally moving the water tank body 2 into the containing cavity 101. The water tank body 2 is rotationally connected with the base 1, and the central axis of the rotation axis 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, and under the driving of the external force, the water tank body 2 can be horizontally rotated along the radial direction of the rotation axis to the outside of the containing cavity 101, so as to move the water tank body 2 out of the base 1, and 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 lock assembly 3 is installed on the water tank body 2, for example, the elastic lock assembly 3 can be located on the side end face of the water tank body 2 close to the bottom of the base 1, and the base 1 is provided with a limiting groove 102. The bottom of the elastic lock assembly 3 can be lifted and lowered in the vertical direction. When the water tank is rotated to the containing cavity 101 and gap-fitted with the base 1, the elastic lock assembly 3 can extend into the limiting groove 102, and the abutting fit between the elastic lock assembly 3 and the limiting groove 102 limits the horizontal displacement of the water tank body 2, so as to lock the relative position between the base 1 and the water tank body 2.

[0048] When the water tank device is used to add water, the elastic lock assembly 3 can be pulled upwards, so that the bottom of the elastic lock assembly 3 is lifted and moved out of the limiting groove 102, thereby releasing the locking of the relative position between the base 1 and the water tank body 2. Then the elastic lock assembly 3 is pulled horizontally, thereby driving the water tank body 2 fixed with the elastic lock assembly 3 to rotate horizontally, and the water tank body 2 is rotated out of the accommodating cavity 101, and then the elastic lock assembly 3 is released, and the water tank body 2 is used to add water. After the water is added, the elastic lock assembly 3 is pulled upwards again, so that the elastic lock assembly 3 moves upwards along the water tank body 2, thereby lifting the bottom of the elastic lock assembly 3 and pressing the elastic lock assembly 3, so that the water tank body 2 is rotated into the accommodating cavity 101. After the water tank body 2 is rotated in place, the elastic lock assembly 3 is released, and the elastic lock assembly 3 moves downwards along the water tank body 2 and abuts against the limiting groove 102 by the elastic restoring action of the elastic lock assembly 3.

[0049] Therefore, during the water adding process, the threaded device and the buckle device do not need to be frequently disassembled and assembled, the wear of the fasteners can be avoided (for example, long-term wear causes screw thread slipping, threaded hole damage, buckle failure, etc.), and the service life of the water tank device is reduced. Moreover, during the water adding process, the user only needs to operate the elastic lock assembly 3, and the water adding convenience of the water tank device is greatly improved. In addition, the rotating and fitting mode of the water tank body 2 and the base 1 can improve the disassembly and assembly convenience of the water tank body 2, thereby further improving the convenience of user operation, achieving the effect of cold fan water adding, quick disassembly and assembly, cleaning, etc.

[0050] An optional embodiment of the application is described below with reference to Figures 2-7 As shown in FIG. 1, a first clamping groove 201 extending in the vertical direction is formed in the water tank body 2, and the elastic lock assembly 3 can include a lock housing 31, an elastic extension unit 32, and a first buckle 33. The lock housing 31 is slidingly 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 extension 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 buckle 33 is arranged on the lock housing 31 and is clamped with the first clamping groove 201. Under the action of the elastic extension unit 32 without external force, the first buckle 33 abuts against the bottom of the first clamping groove 201, so that the lock housing 31 extends into the limiting groove 102. When the lock housing 31 is pulled upwards to compress the elastic extension unit 32, the first buckle 33 abuts against the top of the first clamping groove 201, so that the lock housing 31 is lifted out of the limiting groove 102.

[0051] In the embodiment of the present application, a first clamping groove 201 extending in the vertical direction is formed on the side end surface of the water tank body 2, and the elastic locking assembly 3 can include a locking shell 31, an elastic telescopic unit 32, and a first clamping buckle 33. The locking shell 31 is in sliding connection with the side end surface of the water tank body 2, so that the locking shell 31 can slide up and down along the water tank body 2, thereby achieving the lifting movement of the bottom of the elastic locking 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 with the locking shell 31, and the other end of the elastic telescopic unit 32 is in abutment with the water tank body 2. When the locking shell 31 is pushed to slide upward and an abutment force is applied to the elastic telescopic unit 32, the elastic telescopic unit 32 will perform compression movement close to the abutment position of the water tank body 2 under the action of the abutment force, so that the bottom of the locking shell 31 is lifted from the limiting groove 102 to the outside of the limiting groove 102, thereby releasing the locking of the relative position between the base 1 and the water tank body 2. When the locking shell 31 is not subjected to the pushing force, the elastic telescopic unit 32 will recover, at this time, the elastic telescopic unit 32 gradually elongates and drives the locking shell 31 fixedly connected with the elastic telescopic unit 32 to slide downward, so that the bottom of the locking shell 31 is lowered from the outside of the limiting groove 102 to the inside of the limiting groove 102, thereby achieving the position locking between the base 1 and the water tank body 2.

[0053] The first clamping buckle 33 is arranged on the locking shell 31 and is in clamping connection with the first clamping groove 201. The first clamping groove 201 has a certain height in the vertical direction, so that the first clamping buckle 33 can be provided with a certain lifting stroke in the first clamping groove 201. In an example, when the elastic telescopic unit 32 is not subjected to external force (i.e., the locking shell 31 is not subjected to upward pushing force), the elastic telescopic unit 32 will recover, at this time, the elastic telescopic unit 32 gradually elongates and drives the locking shell 31 fixedly connected with the elastic telescopic unit 32 to slide downward, and the first clamping buckle 33 arranged on the locking shell 31 slides downward synchronously. The first clamping buckle 33 slides downward from the top of the first clamping groove 201 to the bottom of the first clamping groove 201, and the bottom of the first clamping groove 201 abuts against the first clamping buckle 33, so as to limit the position of the locking shell 31. Moreover, the bottom of the locking shell 31 is lowered from the outside of the limiting groove 102 to the inside of the limiting groove 102, thereby achieving the position locking between the base 1 and the water tank body 2.

[0054] In other embodiments, when the locking housing 31 is pushed upward to apply a resisting force to the elastic telescopic unit 32, the elastic telescopic unit 32 will compress near the contact point of the water tank body 2 under the action of the resisting force. This allows the bottom of the locking housing 31 to rise from inside the limiting groove 102 to outside the limiting groove 102, releasing the locking of the relative position between the base 1 and the water tank body 2. At this time, the first latch 33 provided on the locking housing 31 slides upward synchronously. The first latch 33 slides upward from the bottom of the first slot 201 to the top of the first slot 201. When the top of the first slot 201 forms a contact with the first latch 33, it restricts the locking housing 31 from sliding further upward. Thus, the first latch 33 and the first sliding groove 202 cooperate to limit the sliding stroke of the locking housing 31.

[0055] An optional embodiment of the invention, referring to... Figure 2 and Figure 4 As shown, the top of the locking housing 31 is provided with an elastic receiving groove 3101. 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 receiving groove 3101. 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.

[0056] In this embodiment of the invention, the top of the locking housing 31 is further provided with an elastic receiving groove 3101, which is used to receive the elastic telescopic unit 32. To improve the sliding stability of the locking housing 31, the number of elastic telescopic units 32 can be at least two, and these at least two elastic telescopic units 32 can be distributed at intervals at the top of the locking housing 31. Those skilled in the art can also determine the number of elastic telescopic units 32 according to actual design requirements, for example, it can be 2, 3, or 4, etc., without further limitation here.

[0057] The elastic expansion unit 32 can include a mounting column 321 and a reset spring 322. The mounting column 321 is fixed in the elastic accommodating groove 3101, for example, the mounting column 321 and the lock buckle shell 31 can be an integral structure. For another example, the mounting column 321 can be clamped and fixed with the lock buckle shell 31. The reset spring 322 is sleeved on the mounting column 321, and one end of the reset spring 322 abuts against the water tank body 2. Wherein, the other end of the reset spring 322 can be interference fit with the bottom of the mounting column 321, so as to realize the fixed connection of the reset spring 322. In another example, the other end of the reset spring 322 can have a hook portion, so as to be hung on the lock buckle shell 31 through the hook portion.

[0058] When the lock buckle shell 31 is pushed to slide upward and abut against the elastic expansion unit 32, the reset spring 322 will make a vertical upward compression movement under the action of the abutting force. The arrangement of the mounting column 321 can also avoid the radial distortion of the reset spring 322, and improve the movement stability of the reset spring 322. Moreover, the bottom of the lock buckle shell 31 is lifted out 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 arranged on the lock buckle shell 31 is also synchronously slid upward. The first buckle 33 slides upward from the bottom of the first clamping groove 201 to the top of the first clamping groove 201, and when the top of the first clamping groove 201 abuts against the first buckle 33, the further sliding of the lock buckle shell 31 is limited. Therefore, the first buckle 33 and the first sliding groove 202 can cooperate with each other to limit the sliding stroke of the lock buckle shell 31, and can also limit the retraction length of the reset spring 322.

[0059] When the lock buckle shell 31 is not subjected to the pushing force, the reset spring 322 will be retracted and recovered. At this time, the reset spring 322 is gradually elongated, and drives the lock buckle shell 31 connected with the reset spring 322 to slide downward, so that the bottom of the lock buckle shell 31 is lowered from outside the limiting groove 102 to inside the limiting groove 102. At this time, the first buckle 33 slides downward from the top of the first clamping groove 201 to the bottom of the first clamping groove 201, and when the bottom of the first clamping groove 201 abuts against the first buckle 33, the position of the lock buckle shell 31 can be limited. Moreover, the bottom of the lock buckle shell 31 is lowered from outside the limiting groove 102 to inside the limiting groove 102, so as to realize the position locking between the base 1 and the water tank body 2.

[0060] An optional embodiment of the application is described with reference to Figure 2 , Figure 3 ,Figure 4 as well as Figure 5 As shown, the bottom of the latch housing 31 is provided with a limiting boss 34. When the first buckle 33 abuts against the bottom of the first slot 201, the limiting boss 34 extends into the limiting groove 102.

[0061] In this embodiment of the invention, a limiting boss 34 is provided at the bottom of the locking housing 31. For example, the limiting boss 34 may extend downward along the bottom of the locking housing 31. The limiting boss 34 is used to abut against the limiting groove 102. For example, when the bottom of the first slot 201 abuts against the first buckle 33, the limiting boss 34 extends into the limiting groove 102 and abuts against the groove wall of the limiting groove 102, thereby locking the relative position between the water tank body 2 and the base 1. For example, the abutment surface shape of the limiting boss 34 and the limiting groove 102 is matched, thereby increasing the abutment area between the limiting boss 34 and the limiting groove 102 to improve the abutment stability.

[0062] In some preferred embodiments, the limiting boss 34 and the locking housing 31 are integrally formed. This improves the connection strength between the limiting boss 34 and the locking housing 31, and reduces the production steps and costs of the elastic locking assembly 3.

[0063] In other alternative implementations, refer to Figure 2 and Figure 6 As shown, a guide groove 104 is also provided on the bottom of the base 1. The number of guide grooves 104 is consistent with the number of limiting protrusions 34. The guide grooves 104 can communicate with the limiting grooves 102, and the bottom of the guide grooves 104 is higher than the height of the limiting grooves 102. The height of the inner bottom of the base 1 is higher than the height of the bottom of the guide grooves 104. Therefore, the limiting protrusions 34 can slide in the guide grooves 104, thereby shortening the sliding stroke of the locking housing 31 or shortening the deformation length of the return spring 322. By raising the limiting protrusions 34 to the bottom of the guide grooves 104, the water tank body 2 can be rotated. Compared with raising the limiting protrusions 34 to the inner bottom of the base 1 before rotating the water tank body 2, the user moves the locking housing 31 by 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 lock assembly 3 further comprises a lock flange 35, which is arranged outwardly extending from the end face of the lock shell 31 away from the water tank body 2.

[0065] In the embodiment of the present application, the elastic lock assembly 3 can further comprise a lock flange 35, which can be located on the end face of the lock shell 31 away from the water tank body 2. For example, the lock flange 35 is fixedly connected with the lock shell 31. Alternatively, the lock flange 35 is an integral structure with the lock shell 31. The lock flange 35 can be located in the middle region of the lock shell 31 and outwardly extend a certain length along the horizontal direction of the lock shell 31. Thus, the lock flange 35 can be regarded as a handle for facilitating the user to pull the lock shell 31.

[0066] When it is necessary to add water in the water tank body 2, the user holds the lock flange 35 and pushes the lock shell 31 to slide upward, so as to apply an abutting force to the elastic extension unit 32. Under the action of the abutting force, the reset spring 322 performs a vertical upward compression movement. Meanwhile, the bottom of the lock shell 31 is lifted from the limiting groove 102 to the outside of the limiting groove 102, thereby releasing the locking of the relative position between the base 1 and the water tank body 2. At this time, the first buckle 33 arranged on the lock shell 31 is synchronously slid upward. The first buckle 33 is slid upward from the bottom of the first clamping groove 201 to the top of the first clamping groove 201. When the top of the first clamping groove 201 abuts against the first buckle 33, the further upward sliding of the lock shell 31 is limited. Further pulling the lock flange 35, thereby driving the water tank body 2 to rotate to the outside of the accommodating cavity 101, and the water tank body 2 is removed from 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 pinches the lock flange 35, pushes the lock housing 31 to slide upward, and applies an abutting force to the elastic expansion 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 towards the direction of the accommodating cavity 101, and the lock housing 31 is simultaneously driven to rotate horizontally into the accommodating cavity 101. The user releases the lock flange 35, and the reset spring 322 will recover when the lock housing 31 is not subjected to a pushing force. At this time, the reset spring 322 gradually elongates and drives the lock housing 31 connected with the reset spring 322 to slide downward, so that the bottom of the lock housing 31 descends from outside the limiting groove 102 to inside the limiting groove 102. At this time, the first buckle 33 slides downward from the top of the first clamping groove 201 to the bottom of the first clamping groove 201. The bottom of the first clamping groove 201 abuts against the first buckle 33 to limit the position of the lock housing 31. The bottom of the lock housing 31 descends from outside the limiting groove 102 to inside the limiting groove 102 to realize the position locking between the base 1 and the water tank body 2.

[0068] Thus, the threaded device and the buckle device do not need to be frequently disassembled during the water adding process, which can avoid the wear of fasteners (such as screw thread slipping, threaded hole damage, buckle failure, etc.) and reduce the service life of the water tank device. During the water adding process, the user only needs to operate the elastic lock assembly 3, which greatly improves the water adding convenience of the water tank device.

[0069] An optional embodiment of the application is shown in Figure 4 , Figure 6 and Figure 7 The side of the water tank body 2 is provided with a vertical sliding groove 202, and the side of the lock housing 31 is provided with a guide rail 4 which is in sliding connection with the sliding groove 202.

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

[0071] An optional embodiment of the application is shown in Figure 2 and Figure 8As shown, the base 1 is provided with a movable hole 103, and the water tank device further comprises a latch 5, which is fixedly connected with 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 are rotationally connected.

[0072] In the embodiment, the base 1 is provided with a movable hole 103, and the water tank device can further comprise a latch 5, which is fixedly connected with the water tank body 2. When connecting the water tank body 2 and the base 1, the water tank body 2 can be placed into the accommodating cavity 101, and the latch 5 is inserted into the movable hole 103 from top to bottom, so that the latch 5 and the movable hole 103 are gap-fitted. Thus, the water tank body 2 is rotated around the latch 5 as the rotating shaft, and when the water tank body 2 is pulled, the water tank body 2 can be rotated out of the accommodating cavity 101. The fitting mode of the latch 5 and the movable hole 103 can improve the convenience of disassembling and assembling the water tank body 2, so as to further improve the convenience of user operation, realize the effect of cold fan overturning and adding water, quick disassembling and cleaning, and the like.

[0073] An optional embodiment of the application is shown in Figure 1 , Figure 2 and Figure 9 The water tank device further comprises a cover plate 6, which is arranged between the water tank body 2 and the elastic lock catch assembly 3, and is fixedly connected with the water tank body 2 to close the elastic lock catch assembly 3.

[0074] In the embodiment, the water tank device can further comprise a cover plate 6, which is arranged between the water tank body 2 and the elastic lock catch assembly 3 to protect the devices on the elastic lock catch 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 with the water tank body 2, and can also cover the outer end surface of the water tank body 2 and play the role of protecting the water tank body 2.

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

[0076] An optional embodiment of the application is shown in Figure 2 , Figure 6 , Figure 7 and Figure 9As shown, the water tank body 2 and the cover plate 6 are clamped and fixed.

[0077] In the embodiment of the present application, 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 corresponding to the assembly area of the first buckle position 9, so that the clamping and fixing between the water tank body 2 and the cover plate 6 can be formed by the cooperation of the first buckle position 9 and the second buckle position 10. For example, the first buckle position 9 is an integral structure with the water tank body 2. For another example, the second buckle position 10 is an integral structure with the cover plate 6.

[0078] In some preferred embodiments, the connection between the water tank body 2 and the cover plate 6 can also be provided with a second buckle and a second slot, etc., to form multi-point clamping, so as to improve the connection firmness between the water tank body 2 and the cover plate 6.

[0079] An optional embodiment of the present application is shown in Figure 2 , Figure 3 , Figure 6 and Figure 8 As shown, the outer side of the water tank body 2 is provided with a bearing rib 7, the inner side of the base 1 is provided with a bearing lug 8, the bearing rib 7 is located above the bearing lug 8, and forms pressure contact with the bearing lug 8.

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

[0081] As some preferred embodiments, the bearing rib 7 is an integral structure with the water tank body 2, and the bearing lug 8 is an integral structure with the base 1.

[0082] An optional embodiment of the present application is that the bearing rib 7 is arranged around the water tank body 2 in the horizontal direction.

[0083] In the embodiment of the present application, the bearing rib 7 is arranged along the horizontal direction of the water tank body 2, which can be understood as that the bearing rib 7 can surround the outer end surface of the water tank body 2 along the horizontal direction of the water tank body 2. For example, in order to facilitate the limiting of the base 1 to the water tank body 2 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 bolt 5 is less than one half of a circle, and the bearing rib 7 is arranged in the end surface area, which can ensure that the bearing rib 7 is always in surface contact with the bearing lug 8 during the rotation of the water tank body 2.

[0084] In summary, the embodiment of the present application discloses a water tank device which can include a base 1, a water tank body 2 and an elastic lock assembly 3. The base 1 is provided with a receiving cavity 101 with an opening facing one side, and the bottom of the base 1 is provided with a limiting groove 102. The water tank body 2 is located in the receiving cavity 101 and rotationally connected with the base 1, and under the driving of external force, the water tank body 2 is rotated out of the receiving cavity 101. The elastic lock 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. In the case of pulling up the elastic lock assembly 3, the elastic lock assembly 3 moves out of the limiting groove 102 to release the locking of the relative position of the base 1 and the water tank body 2. Therefore, when water needs to be added, the elastic lock assembly 3 is pulled up to release the locking of the relative position of the base 1 and the water tank body 2, and the water tank body 2 is rotated to move out of the receiving cavity 101 for water adding. After water adding is completed, the elastic lock assembly 3 is pulled up to rotate the water tank body 2 into the receiving cavity 101, and the elastic lock assembly 3 is released to fix the water tank body 2. Thus, on the basis of ensuring the service life of the water tank device, the water adding convenience of the water tank device can also be improved.

[0085] The embodiment of the present application also discloses a cold fan, which comprises the water tank device as described in any one of the above embodiments.

[0086] In the embodiment of the present application, the cold fan is a refrigeration device which mainly reduces the air temperature by water evaporation and heat absorption, and blows out the air with lower temperature by a fan to achieve environmental cooling. The cold fan stores a certain amount of water for cooling by integrating the above water tank device.

[0087] The water tank device can 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, which is used to accommodate the water tank body 2, and the opening is used for the water tank body 2 to move horizontally into the receiving cavity 101. The water tank body 2 is rotationally connected with the base 1, and the central axis of the rotation axis 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, and under the driving of the external force, the water tank body 2 can rotate horizontally along the radial direction of the rotation axis to the outside of the receiving cavity 101, so as to move the water tank body 2 out of 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 assembly 3 is installed on the water tank body 2, for example, the elastic locking assembly 3 can be located on the side end face of the water tank body 2 close to the bottom of the base 1, and the base 1 is provided with a limiting groove 102. The bottom of the elastic locking assembly 3 can move up and down in the vertical direction. When the water tank is rotated to the receiving cavity 101 and gap-fitted with the base 1, the elastic locking assembly 3 can extend into the limiting groove 102, and through the abutting fit between the elastic locking assembly 3 and the limiting groove 102, the horizontal displacement of the water tank body 2 is limited, so as to lock the relative position between the base 1 and the water tank body 2.

[0089] When the water tank device is used to add water, the elastic locking assembly 3 can be pulled up, so that the bottom of the elastic locking assembly 3 moves up and out of the limiting groove 102, thereby releasing the locking of the relative position between the base 1 and the water tank body 2. Then the elastic locking assembly 3 is pulled horizontally, so as to drive the water tank body 2 fixed with the elastic locking assembly 3 to rotate horizontally, and after the water tank body 2 is rotated to the outside of the receiving cavity 101, the elastic locking assembly 3 is released, and the water tank body 2 is used to add water. After the water adding is completed, the elastic locking assembly 3 is pulled up again, so that the elastic locking assembly 3 moves upward along the water tank body 2, thereby lifting the bottom of the elastic locking assembly 3 and pressing the elastic locking assembly 3, so that the water tank body 2 rotates into the receiving cavity 101. After the water tank body 2 is rotated in place, the elastic locking assembly 3 is released, and through the elastic recovery of the elastic locking assembly 3, the elastic locking assembly 3 moves downward along the water tank body 2 and abuts with the limiting groove 102.

[0090] Therefore, the threaded device and the buckle device do not need to be frequently disassembled during the water adding process, wear of the fastener (such as screw thread slipping, threaded hole damage, buckle failure, etc. caused by long-term wear) can be avoided, and the service life of the water tank device is reduced. Moreover, the user only needs to operate the elastic lock assembly 3 during the water adding process, and the water adding convenience of the water tank device is greatly improved.

[0091] Moreover, the rotating fitting mode of the water tank body 2 and the base 1 can improve the disassembly and assembly convenience of the water tank body 2, thereby further improving the operation convenience of the user, achieving the effects of cold fan water adding, quick disassembly and assembly, cleaning, etc.

[0092] In summary, the embodiment of the present application also discloses a cold fan, which can include a base 1, a water tank body 2, and an elastic lock assembly 3. The base 1 is provided with a receiving cavity 101 with an opening facing one side, and the bottom of the base 1 is provided with a limiting groove 102. The water tank body 2 is located in the receiving cavity 101 and is rotationally connected with the base 1. Under the driving 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 lock 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 lock assembly 3 is pulled up, the elastic lock assembly 3 moves out of the limiting groove 102, and the locking of the relative position of the base 1 and the water tank body 2 is released. Therefore, when water needs to be added, the elastic lock assembly 3 is pulled up to release the locking of the relative position of the base 1 and the water tank body 2, and the water tank body 2 is rotated to move out of the receiving cavity 101 for water adding. After water adding is completed, the elastic lock assembly 3 is pulled up to rotate the water tank body 2 into the receiving cavity 101, and the elastic lock assembly 3 is released to fix the water tank body 2. Therefore, on the basis of ensuring the service life of the cold fan, the water adding convenience of the cold fan is also improved.
