Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and particularly relates to a waterproof structure of a cold fan and a cold fan. Background Art

[0002] A cold fan is a temperature regulating appliance that uses the principle of evaporation heat absorption of water to lower the ambient temperature.

[0013] One of the first water blocking portion and the second water blocking portion is provided with water blocking ribs, and the other is provided with positioning grooves; when the first water blocking portion and the second water blocking portion are joined and connected, the water blocking ribs are inserted into the positioning grooves.

[0014] It further includes at least one second water blocking structure, the second water blocking structure is arranged in the first chamber and extends from the end of the first chamber far away from the second chamber to the end close to the second chamber; a wiring cavity suitable for allowing electrical lines to pass through is formed between the second water blocking structure and the housing structure.

[0015] There are two second water blocking structures, which respectively form the wiring cavity with the housing structure, and a receiving cavity suitable for receiving the water tank assembly is formed between the two second water blocking structures.

[0016] The two wiring cavities are arranged oppositely.

[0017] It further includes a third water blocking structure, the third water blocking structure is arranged in the second chamber, with one side corresponding to the electrical components of the cold fan and the other side corresponding to the water receiving structure of the cold fan.

[0018] The third water blocking structure is a partition plate.

[0019] It further includes a first drainage structure arranged on the first water blocking portion, and the first drainage structure communicates the first chamber with the outside of the front case.

[0020] The first drainage structure includes:

[0021] A groove is formed on the first water blocking portion and communicates with the first chamber;

[0022] A first drainage hole penetrates through the groove wall on the side of the groove away from the rear case and extends to the outside of the front case.

[0023] It further includes a second drainage structure, and the second drainage structure communicates the first chamber with the outside of the rear case.

[0024] The second drainage structure includes:

[0025] A second drainage hole is arranged on the water receiving structure of the cold fan and communicates with the first chamber;

[0026] A third drainage hole is arranged on the air inlet structure of the cold fan and communicates the second drainage hole with the air inlet on the air inlet structure.

[0027] The second drainage structure further includes a drainage channel which is arranged on the water receiving structure and communicates the second drainage hole and the third drainage hole.

[0029] The waterproof structure of the above-mentioned cooling fan;

[0030] A water tank assembly arranged in the first chamber;

[0031] Electrical components arranged in the second chamber.

[0032] The technical solution of the present invention has the following effects:

[0033] 1. The waterproof structure of the cooling fan provided by the present invention includes: a housing structure forming an installation cavity; a first water blocking structure arranged in the installation cavity and dividing the installation cavity into a first chamber suitable for accommodating the water tank assembly and a second chamber suitable for accommodating the electrical components. By arranging the first water blocking structure, the installation cavity is divided into the first chamber and the second chamber, and the water tank assembly is accommodated in the first chamber, and the electrical components are accommodated in the second chamber. When the cooling fan is bumped and shakes or topples over, even if the water in the water tank assembly spills out, due to the separation of the first water blocking structure, it will not flow onto the electrical components in the second chamber, which can effectively prevent the damage of the electrical components and reduce potential safety hazards at the same time.

[0034] 2. The waterproof structure of the cooling fan provided by the present invention, the first water blocking structure includes: a first water blocking portion extending inwards from the inner wall of the front shell; a second water blocking portion extending inwards from the inner wall of the rear shell and joined with the first water blocking portion. On the one hand, the first water blocking portion directly extends inwards from the inner wall of the front shell, so that there is no gap between the first water blocking portion and the front shell. Similarly, the second water blocking portion directly extends inwards from the inner wall of the rear shell, so that there is no gap between the second water blocking portion and the rear shell. This can reduce the gap generated when the first water blocking structure divides the installation cavity, making the first chamber and the second chamber have better sealing performance. On the other hand, when the second water blocking portion is joined with the first water blocking portion, it can also improve the sealing performance at the joint of the first water blocking portion and the second water blocking portion.

[0035] 3. The waterproof structure of the cooling fan provided by the present invention, one of the first water blocking portion and the second water blocking portion is provided with water blocking ribs, and the other is provided with positioning grooves; when the first water blocking portion is joined with the second water blocking portion, the water blocking ribs are inserted into the positioning grooves. This can reduce the splicing gap and enhance the sealing performance.

[0036] 4. The waterproof structure of the cold fan provided by the present invention further includes at least one second water-blocking structure, which is arranged in the first chamber and extends from the end of the first chamber far away from the second chamber towards the end close to the second chamber; a wiring cavity suitable for allowing electrical lines to pass through is formed between the second water-blocking structure and the housing structure. In this way, the electrical lines and the water tank assembly can be separated in different chambers, preventing the water spilled from the water tank from falling onto the electrical lines and entering the electrical components along the electrical lines when the cold fan is bumped and shakes or topples, thus damaging the electrical components, and effectively improving safety.

[0037] 5. The waterproof structure of the cold fan provided by the present invention further includes a third water-blocking structure, which is arranged in the second chamber, with one side corresponding to the electrical components of the cold fan and the other side corresponding to the water receiving structure of the cold fan.

[0038] 6. The waterproof structure of the cold fan provided by the present invention further includes a first drainage structure arranged on the first water-blocking part, and the first drainage structure communicates the first chamber with the outside of the front shell. When the cold fan is bumped and the front shell topples downwards, the water spilled from the water tank assembly can flow to the outside of the front shell through the first drainage structure, preventing it from accumulating in the cold fan and finally flowing onto the electrical components.

[0039] 7. The waterproof structure of the cold fan provided by the present invention further includes a second drainage structure, and the second drainage structure communicates the first chamber with the outside of the rear shell. When the cold fan is bumped and the rear shell topples downwards, the water spilled from the water tank assembly can flow to the outside of the rear shell through the second drainage structure, preventing it from accumulating in the cold fan and finally flowing onto the electrical components.

Detailed implementation manners

[0051] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0052] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0053] As Figures 1-8 shown, this embodiment provides a waterproof structure for a cold fan, including a housing structure and a first water-blocking structure.

[0054] The housing structure forms an installation cavity.

[0055] The first water blocking structure is arranged in the installation cavity and divides the installation cavity into a first chamber 11 suitable for accommodating the water tank assembly and a second chamber 12 suitable for accommodating electrical components.

[0056] By arranging the first water blocking structure, the installation cavity is divided into the first chamber 11 and the second chamber 12. The water tank assembly is accommodated in the first chamber 11, and the electrical components are accommodated in the second chamber 12. When the cold fan is touched and shakes or topples over, even if the water in the water tank assembly spills out, due to the separation of the first water blocking structure, it will not flow onto the electrical components in the second chamber 12, which can effectively prevent damage to the electrical components and reduce potential safety hazards at the same time.

[0057] There is no limitation on the specific structural form of the housing structure. In this embodiment, the housing structure includes a front shell 21 and a rear shell 22, and the installation cavity is surrounded by the docking of the front shell 21 and the rear shell 22.

[0058] There can be various specific structural forms of the first water blocking structure. In this embodiment, the first water blocking structure includes a first water blocking part 31 and a second water blocking part 32. Among them, the first water blocking part 31 extends inward from the inner wall of the front shell 21; the second water blocking part 32 extends inward from the inner wall of the rear shell 22 and is spliced and connected with the first water blocking part 31. On the one hand, the first water blocking part 31 directly extends inward from the inner wall of the front shell 21, so that there is no gap between the first water blocking part 31 and the front shell 21. Similarly, the second water blocking part 32 directly extends inward from the inner wall of the rear shell 22, so that there is no gap between the second water blocking part 32 and the rear shell 22. This can reduce the gap generated by the first water blocking structure when dividing the installation cavity, making the first chamber 11 and the second chamber 12 have better sealing performance; on the other hand, when the second water blocking part 32 is spliced and connected with the first water blocking part 31, it can also improve the sealing performance at the connection of the first water blocking part 31 and the second water blocking part 32.

[0059] As a changeable implementation manner, the first water blocking structure can also only include the first water blocking part 31 and extend from the inner wall of the front shell 21 to the position where it contacts the inner wall of the rear shell 22, or only include the second water blocking part 32 and extend from the inner wall of the rear shell 22 to the position where it contacts the inner wall of the front shell 21. As a changeable implementation manner, the first water blocking part 31 can also be detachably connected to the front shell 21, and the second water blocking part 32 can also be detachably connected to the rear shell 22.

[0060] The first water retaining part 31 is provided with a water retaining rib 311, and the second water retaining part 32 is provided with a positioning groove 321; when the first water retaining part 31 and the second water retaining part 32 are spliced and connected, the water retaining rib 311 is inserted into the positioning groove 321. This can reduce the splicing gap and enhance the sealing performance. In this embodiment, on the side wall of the positioning groove 321 far from the first chamber 11 and near the notch, a guiding inclined surface 322 is formed. As an alternative embodiment, it can also be that the second water retaining part 32 is provided with a water retaining rib 311, and the first water retaining part 31 is provided with a positioning groove 321.

[0061] The waterproof structure provided in this embodiment further includes at least one second water retaining structure 4. The second water retaining structure 4 is disposed in the first chamber 11 and extends from the end of the first chamber 11 far from the second chamber 12 towards the end close to the second chamber 12; a wiring cavity 41 suitable for allowing electrical lines to pass through is formed between the second water retaining structure 4 and the housing structure. This can separate the electrical lines and the water tank assembly in different chambers, preventing the water spilled from the water tank from falling onto the electrical lines and entering the electrical components along the electrical lines when the cold fan is touched and shakes or topples, thus damaging the electrical components, and can effectively improve safety.

[0062] In this embodiment, there are two second water retaining structures 4, which respectively form a wiring cavity 41 with the housing structure, and a receiving cavity suitable for receiving the water tank assembly is formed between the two second water retaining structures 4. Among them, the two wiring cavities 41 are arranged oppositely.

[0063] The waterproof structure provided in this embodiment further includes a third water retaining structure 5. The third water retaining structure 5 is disposed in the second chamber 12, with one side corresponding to the electrical components of the cold fan and the other side corresponding to the water receiving structure 8 of the cold fan. This can effectively prevent the water in the water receiving structure 8 from flowing onto the electrical components, further prevent damage to the electrical components, and improve safety.

[0064] There is no limitation on the specific structural form of the third water retaining structure 5. In this embodiment, the third water retaining structure 5 is a partition board.

[0065] The waterproof structure provided in this embodiment further includes a first drainage structure disposed on the first water retaining part 31. The first drainage structure communicates the first chamber 11 with the outside of the front shell 21.

[0066] There can be various specific structural forms of the first drainage structure. In this embodiment, the first drainage structure includes a groove 61 and a first drainage hole 62.

[0067] The groove 61 is formed on the first water retaining part 31 and communicates with the first chamber 11.

[0068] The first drainage hole 62 penetrates through the side wall of the groove 61 far from the rear shell 22 and extends to the outside of the front shell 21.

[0069] When the cold fan is knocked over with the front shell 21 facing downwards, the water spilled from the water tank assembly in the first chamber 11 first flows into the groove 61, and then flows outside the front shell 21 through the first drain hole 62 provided on the side wall of the groove 61, which can effectively prevent the water from accumulating in the cold fan and finally flowing onto the electrical components.

[0070] The waterproof structure provided in this embodiment further includes a second drainage structure, and the second drainage structure communicates the first chamber 11 with the outside of the rear shell 22.

[0071] There can be various specific structural forms of the second drainage structure. In this embodiment, the second drainage structure includes a second drain hole 71, a third drain hole 72, and a drainage channel 73.

[0072] The second drain hole 71 is provided on the water receiving structure 8 of the cold fan and communicates with the first chamber 11.

[0073] The third drain hole 72 is provided on the air inlet structure 9 of the cold fan and communicates the second drain hole 71 with the air inlet on the air inlet structure 9.

[0074] The drainage channel 73 is provided on the water receiving structure 8 and communicates the second drain hole 71 and the third drain hole 72.

[0075] When the cold fan is knocked over with the rear shell 22 facing downwards, the water spilled from the water tank assembly in the first chamber 11 first flows into the drainage channel 73 of the water receiving structure 8 through the second drain hole 71, then flows to the air inlet on the air inlet structure 9 through the third drain hole 72, and finally flows out of the rear shell 22 through the air inlet, which can effectively prevent the water from accumulating in the cold fan and finally flowing onto the electrical components. Especially when the cold fan is knocked over and the docking joint of the front shell 21 and the rear shell 22 faces downwards, both the first drainage structure and the second drainage structure can play a drainage role.

[0076] This embodiment also provides a cold fan, including the waterproof structure of the cold fan described above, as well as a water tank assembly, electrical components, a water receiving structure 8, an air inlet structure 9, etc. Among them, the water tank assembly is provided in the first chamber 11; the electrical components are provided in the second chamber 12. The water receiving structure 8 is a water receiving box.

[0077] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
