Description

Technical Field

[0001] The present application relates to the field of cold fans, and in particular, to a connection structure for a double water tank and a cold fan thereof. Background Art

[0002] A cold fan is a device that uses the principle of water evaporation to absorb heat to lower the air temperature. It combines the advantages of an air conditioner and a fan and is widely popular among consumers.

[0003] In the related art, a cold fan is usually equipped with a water storage tank. Water is pumped into the refrigeration component through a water pump for cooling, and then cold air is sent out through a fan. Among them, in order to improve the refrigeration effect of the cold fan, the cold fan can also be equipped with a refrigeration water tank. The water storage tank and the refrigeration water tank are connected by a connecting pipe so that the water in the water storage tank flows into the refrigeration water tank.

[0004] However, in actual application, the water in the water storage tank flows into the refrigeration water tank at a relatively fast speed, resulting in a relatively fast heating speed of the water in the refrigeration water tank, which affects the user experience and thus needs to be improved. Summary of the Utility Model

[0005] In order to reduce the heating speed of the water in the refrigeration water tank, in a first aspect, the present application provides a connection structure for a double water tank.

[0006] The connection structure for a double water tank provided by the present application adopts the following technical solution:

[0007] A connection structure for a double water tank includes a water storage tank, a refrigeration water tank, and a connecting pipe; the connecting pipe includes a water inlet part, a water outlet part, and a buffer part; the water inlet part is communicated with the water storage tank, the water outlet part is communicated with the refrigeration water tank; the buffer part is arranged in a spiral shape and is respectively communicated with the water inlet part and the water outlet part at both ends.

[0008] By adopting the above technical solution, in actual application, the water in the water storage tank flows into the refrigeration water tank through the water inlet part, the water outlet part, and the buffer part in sequence. Since the buffer part is arranged in a spiral shape, the water in the water storage tank can flow into the refrigeration water tank later, and the heat dissipation time of the water is increased, thereby reducing the heating speed of the water in the refrigeration water tank, making the water cooling effect better, and improving the user experience.

[0009] Preferably, the water inlet part is arranged on one side of the water storage tank close to the refrigeration water tank, the water outlet part is arranged on one side of the refrigeration water tank close to the water storage tank, and the buffer part is arranged between the water storage tank and the refrigeration water tank and is arranged along the length direction of the water storage tank.

[0010] By adopting the above technical solution, even if the buffer part is arranged in a spiral shape, the overall size of the connection structure of the double water tanks can be ensured to be small, so as to reduce the occupied space and ensure the overall structure of the cold fan is compact.

[0011] Preferably, the connecting pipe further includes an extension part, and both ends of the extension part are respectively communicated with the buffer part and the water outlet part and are arranged along the length direction of the water storage tank.

[0012] By adopting the above technical solution, by setting the extension part, under the original overall size, the flow distance of water in the connecting pipe can be further increased, thereby further increasing the heat dissipation time of water.

[0013] Preferably, the inner diameter of one end of the extension part close to the water outlet part is smaller than that of the other end.

[0014] By adopting the above technical solution, by setting the inner diameter of one end of the extension part close to the water inlet part to be smaller than that of the other end, the water flowing from the extension part into the water outlet part can be slowed down, thereby further reducing the heating speed of the water flow in the refrigeration water tank.

[0015] Preferably, one end of the extension part close to the buffer part is arranged to gradually reduce in diameter towards the other end.

[0016] By adopting the above technical solution, by setting one end of the extension part close to the buffer part to gradually reduce in diameter towards the other end, it can be realized that the water flowing from the extension part into the water outlet part is smaller, and the flow stability of water in the extension part can be ensured.

[0017] Preferably, the water inlet part is detachably connected to one side of the water storage tank close to the refrigeration water tank, and the water outlet part is detachably connected to one side of the refrigeration water tank close to the water storage tank.

[0018] By adopting the above technical solution, by setting the water inlet part to be detachably connected to the water storage tank and the water outlet part to be detachably connected to the refrigeration water tank, the connecting pipe can be disassembled for maintenance or replacement.

[0019] Preferably, the connection structure of the double water tanks further includes a connecting piece, the connecting piece includes a first connecting part and a second connecting part, one end of the first connecting part is rotatably connected in the second connecting part, the other end is threadedly connected to the water storage tank, and the water inlet part is threadedly connected to one end of the second connecting part far from the first connecting part.

[0020] By adopting the above technical solution, by setting the connecting piece, it can be realized that the water inlet part is detachably connected to the water storage tank, and the structure of the connecting piece is simple and easy to install, so as to facilitate the installation and disassembly of the water inlet part.

[0021] Preferably, a rotating groove is formed at one end of the first connecting part close to the second connecting part.

[0022] By adopting the above technical solution, a rotating groove is provided to facilitate the rotation of the first rotating part, thereby facilitating the installation of the connecting piece on the water storage tank.

[0023] In a second aspect, the present application provides a cold fan.

[0024] The cold fan provided by the present application adopts the following technical solution:

[0025] A cold fan includes the connection structure of the double water tanks described above.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The water in the water storage tank flows into the refrigeration water tank through the water inlet part, the water outlet part and the buffer part in sequence.

[0036] Reference herein to "embodiments" means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments.

[0037] The following further elaborates on this application with reference to the Figures 1-4 drawings.

[0038] An embodiment of this application discloses a connection structure for a dual water tank.

[0039] Embodiment 1:

[0040] Referring to Figure 1 , the connection structure of the dual water tank includes a storage water tank 1, a refrigeration water tank 2, and a connecting pipe 3. Both the storage water tank 1 and the refrigeration water tank 2 are in the shape of rectangular boxes, and the storage water tank 1 is located above the refrigeration water tank 2. Among them, the connecting pipe 3 includes a water inlet part 31, a water outlet part 32, and a buffer part 33. Both the water inlet part 31 and the buffer part 33 are circular pipes. One end of the water inlet part 31 is fixedly connected to the storage water tank 1 so that the water inlet part 31 is in communication with the storage water tank 1. One end of the water outlet part 32 is fixedly connected to the refrigeration water tank 2 so that the water outlet part 32 is in communication with the refrigeration water tank 2. The buffer part 33 is a spiral circular pipe and both ends are respectively fixedly connected to the water inlet part 31 and the water outlet part 32 so that the buffer part 33 is in communication with the water inlet part 31 and the water outlet part 32.

[0041] In practical applications, the water in the storage water tank 1 flows into the refrigeration water tank 2 successively through the water inlet part 31, the water outlet part 32, and the buffer part 33. Under the action of the spiral buffer part 33, the time for the water to flow in the connecting pipe 3 can be prolonged, so that the water in the storage water tank 1 can flow into the refrigeration water tank 2 later, and the water can be fully cooled in the buffer part 33, thereby reducing the speed at which the water in the refrigeration water tank 2 becomes hot, making the cooling effect of the water cooling better, and improving the user experience.

[0042] In some embodiments, the water inlet part 31 and the water outlet part 32 are arranged vertically. The upper end of the water inlet part 31 is fixedly connected to the lower side of the water storage tank 1, and the lower end of the water outlet part 32 is fixedly connected to the upper side of the refrigeration tank 2. At the same time, the buffer part 33 is arranged along the length direction of the water storage tank 1, so that the connecting pipe 3 is located between the water storage tank 1 and the refrigeration tank 2. Even if the buffer part 33 is arranged in a spiral shape, it can ensure that the connection structure of the double tanks is compact, making the overall size smaller to reduce the occupied space, thereby ensuring the compact structure of the cold fan.

[0043] The implementation principle of this embodiment is as follows: In practical applications, the water in the water storage tank 1 flows into the refrigeration tank 2 through the water inlet part 31, the water outlet part 32 and the buffer part 33 in sequence. Under the action of the spiral buffer part 33, the time for the water to flow in the connecting pipe 3 can be prolonged, so that the water in the water storage tank 1 can flow into the refrigeration tank 2 later, and the water can be fully cooled in the buffer part 33, thereby reducing the speed at which the water in the refrigeration tank 2 becomes hot, making the water cooling effect better, and improving the user experience.

[0044] Embodiment 2:

[0045] Referring to Figure 2 , the other structures of this embodiment are the same as those of Embodiment 1. The difference is that the connecting pipe 3 further includes an extension part 34. One end of the extension part 34 is fixedly connected to the end of the buffer part 33 away from the water inlet part 31, and the other end is fixedly connected to the end of the water outlet part 32 close to the buffer part 33, so that the extension part 34 is communicated with the buffer part 33 and the water outlet part 32, and the extension part 34 is arranged along the length direction of the water storage tank 1. In this way, the distance for the water to flow in the connecting pipe 3 is further increased, and the water in the water storage tank 1 can flow into the refrigeration tank 2 later. At the same time, the extension part 34 arranged along the length direction of the water storage tank 1 can also ensure the overall size of the original connection structure of the double tanks.

[0046] In some embodiments, the inner diameter of the extension part 34 at the end close to the buffer part 33 is larger than that at the end close to the water outlet part 32, so as to slow down the water flowing from the extension part 34 into the water outlet part 32, thereby further reducing the speed at which the water in the refrigeration tank 2 becomes hot, making the water cooling effect better, and further improving the user experience.

[0047] In some embodiments, the end of the extension part 34 close to the buffer part 33 is arranged to gradually reduce in diameter towards the end close to the water outlet part 32, so as to make the water flowing from the extension part 34 into the water outlet part 32 smaller. At the same time, the flow stability of the water in the extension part 34 can be ensured.

[0048] Embodiment 3:

[0049] Referring to Figure 3The other structures of this embodiment are the same as those of embodiment 1, except that the upper end of the water inlet portion 31 is detachably connected to the lower side of the water storage tank 1, and the lower end of the water outlet portion 32 is detachably connected to the lower side of the refrigeration water tank 2, so as to realize the detachable connection between the connecting pipe 3 and the water storage tank 1 and the refrigeration water tank 2, and the connecting pipe 3 can be disassembled as a whole for maintenance or replacement during use.

[0050] Reference Figure 3 and Figure 4 In some embodiments, the connection structure of the double water tank further includes a connector 4, which includes a first connector 41 and a second connector 42. The first connector 41 and the second connector 42 are both arranged in a circular tube shape, and the first connector 41 and the second connector 42 are arranged vertically and coaxially. The lower end of the first connector 41 is rotatably connected to the second connector 42 and the upper end is threadedly connected to the water storage tank 1, so that the connector 4 is installed on the water storage tank 1, and the upper end of the water inlet 31 is threadedly connected to the lower end of the second connector 42. Among them, since the first connector 41 is rotatably connected to the second connector 42, when installing the water inlet 31, it is only necessary to rotate the second connector 42 to realize the threaded connection of the water inlet 31. The structure is simple and the operation is convenient, so that it is easy to realize the installation and disassembly of the water inlet 31. It should be noted that a sealing ring, a sealing pad, a waterproof rubber strip, etc. may be provided between the first connection part 41 and the second connection part 42, and this application does not limit this, so as to ensure the sealing between the first connection part 41 and the second connection part 42, and to prevent water from flowing out from between the first connection part 41 and the second connection part 42 as much as possible. In addition, in this embodiment, the water outlet 32 ​​is also installed in the refrigeration water tank 2 through the connecting member 4, so as to facilitate the installation and removal of the connecting pipe 3.

[0051] Reference Figure 4 In some embodiments, a rotation groove 43 is formed at the lower end of the first connecting portion 41, and the rotation groove 43 is a regular hexagonal groove. When the connecting member 4 is installed in the water tank 1, an Allen wrench is inserted into the rotation groove 43 to facilitate the rotation of the first connecting portion 41, thereby facilitating the installation of the connecting member 4 in the water tank 1.

[0052] The embodiment of the present application also discloses a cooling fan.

[0053] The cooling fan includes the double water tank connection structure described in the above embodiment.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
