Description

Technical Field

[0001] The invention relates to the technical field of household appliance manufacturing, and in particular to a water-cooling fan. Background Art

[0002] At present, most of the water-cooling fans on the market achieve humidification by setting a water circulation device in the body, and pumping water into the air duct through the water circulation device. The general structure of the water circulation device includes a water tank, a water outlet channel, a water curtain channel and a return channel. The water tank is generally set at the bottom of the body, and water is pumped into the water outlet channel by a water pump. The water in the water outlet channel falls from above the water curtain, a part of which is absorbed by the water curtain, and the rest of the water flows back to the water tank through the return channel. The structure is complex and the production cost is high. After the water-cooling fan is started, the water pump needs to work continuously to ensure that the air passing through the water curtain can be humidified. The air inlet and air outlet of most existing water-cooling fans are set on the upper side of the body and opposite to each other, and the fan assembly is set between the air inlet and the air outlet. The water curtain of the water circulation device is set between the air inlet and the fan assembly. Since the water curtain is continuously irrigated and the distance between the fan assembly and the water curtain is close, water droplets may be directly pumped out during the process of the fan assembly pumping out air, which is not conducive to improving user experience. Moreover, long-term operation causes the water pump to consume large amounts of electricity and be easily damaged, which is not conducive to saving usage costs.

[0003] As described above, the structure of the existing water-cooling fan needs to be further improved to simplify the internal structure of the water-cooling fan and improve the performance of the water-cooling fan, thereby reducing costs and improving user experience. Summary of the invention

DETAILED DESCRIPTION

[0028] The technical solution of the present invention is further described below with reference to the accompanying drawings:

[0029] In the description of the present invention, it is necessary to understand that the orientations or positional relationships indicated by “upper”, “lower”, “front”, “back”, “horizontal”, “inside”, “outside”, etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] See also Figure 1-9 As shown, the present invention discloses a water-cooling fan, comprising a body shell 1, a fan assembly 3 and a humidifying assembly 4, the body shell 1 is provided with an air inlet on the lower side, and an air outlet 111 on the upper side, the humidifying assembly 4 is provided with an ascending air duct, the fan assembly 3 and the humidifying assembly 4 are arranged in the body shell 1 from top to bottom, the ascending air duct is connected with the air inlet, and the fan assembly 3 is connected with the air outlet 111. When the fan assembly 3 is started, the airflow can enter from the air inlet, pass through the ascending air duct and the fan assembly 3 in sequence, and then be discharged from the air outlet 111.

[0031] See also Figure 2 ,4 As shown in Figure 7, the humidification assembly 4 includes a water tank 41, a water receiving trough 42 and a water absorption filter 43. The water absorption filter 43 is provided with a first air channel 431, the water tank 41 is provided with a second air channel 411, the water absorption filter 43 is arranged in the water receiving trough 42, the water tank 41 is arranged on the water absorption filter 43, the first air channel 431 and the second air channel 411 form the rising air channel, and the water tank 41 can be replenished according to the water level of the water receiving trough 42. Since the water absorption filter 43 can automatically absorb water, there is no need to set up an irrigation structure, and the problem of excessive or insufficient humidity due to too much or too little water can be avoided; the water tank 41 can replenish water according to the water level of the water receiving trough 42, which can avoid affecting the humidification function of the body due to the water level in the water receiving trough 42 being too high or too low.

[0032] The water absorption filter 43 is in a circular ring shape, and the inner ring of the water absorption filter 43 is the first air duct 431; so that the air intake effect in all directions of the body is consistent, therefore, the air inlet can be set on any side of the body shell 1; in addition, the circular ring design is also conducive to the convenience of processing and manufacturing.

[0033] A drain valve 5 is also included between the water tank 41 and the water receiving trough 42. The drain valve 5 includes a valve stem 51 and a lever assembly 52. ​​A drain port 412 is provided at the bottom of the water tank 41, and the valve stem 51 is arranged in the drain port 412; the lever assembly 52 includes a short lever arm 521 and a long lever arm 522. The lever assembly 52 is arranged in the water receiving trough 42, and the short lever arm 521 abuts against the lower end of the valve stem 51. A float chamber 5221 is provided on the long lever arm 522. When the water level drops, the short lever arm 521 rises and pushes the valve stem 51 to open the drain port 412; when the water level rises, the float chamber 5221 causes the long lever arm 522 to rise, thereby causing the valve stem 51 to close the drain port 412. The drain valve 5 of this solution uses the lever principle and the buoyancy of water to control the opening and closing degree of the drain port 412. The opening and closing degree of the drain port 412 changes according to the rise and fall of the water level of the water receiving tank 42, so that the water tank 41 can supply water to the water receiving tank 42 according to the actual water volume of the water receiving tank 42.

The third connection portion 513 is provided with a through hole 5131 which matches the drain port 412. The bottom of the second connection portion 512 is connected to the inner side of the through hole 5131. When the water in the sink is at a high level, the long lever arm 522 is supported by buoyancy, and the long lever arm 522 and the short lever arm 521 are balanced. At this time, the top block 514 of the valve stem 51 presses against the drain outlet 412 to close the drain outlet 412. When the water level drops, the long lever arm 522 sinks due to gravity, and the short lever arm 521 rises and pushes the valve stem 51 upward to open the drain outlet 412. When the valve stem 51 rises to the through hole 5131 and is connected to the drain outlet 412, the drain outlet 412 is in a fully open state.

[0035] As a preferred solution, the drain valve 5 further includes an elastic member 53 , and the elastic member 53 is sleeved on the second connecting portion 512 to ensure stability when closing the drain outlet 412 .

The maximum speed that can be achieved while ensuring that water droplets are not drawn out is 1800-2000 rpm, the minimum speed in the silent state is 800-900 rpm, and the mid-range speed suitable for daily work and life is 1300-1400 rpm.

[0045] The water-cooling fan of the present invention has a fan assembly 3 arranged on the upper side, and a humidifying assembly 4 and an air inlet are both arranged on the lower side, and an ascending air duct is provided on the humidifying assembly 4. After the airflow enters the body through the air inlet, it is humidified by the humidifying assembly 4 and then enters the ascending air duct, and is sucked by the fan assembly 3 to the air outlet 111 and then discharged.
