Description

Technical Field

[0002] Generally, a cold evaporation fogless humidifier blows air through a fan assembly, so that indoor air enters the humidifier from an air inlet, passes through a wetted filter screen, and then the water on the filter screen is taken away by evaporation and discharged back into the room through an air outlet, thereby achieving the effect of fogless humidification. At present, in the cold evaporation fogless humidifiers on the market, the filter screen is generally directly arranged above the water tank, and the lower end of the filter screen is immersed in water or water is pumped to the upper part of the filter screen through a water pump for dripping to wet the filter screen.

Among them, the water tank 2 can be provided with a first water outlet 22 on the side wall or the bottom for connecting to the water passage 21, and the position of the first water outlet 22 is higher than the highest water level surface of the water tank 32, so that the water in the water tank 2 can flow from the water passage 21 to the water tank 32 under the action of gravity. The humidifying assembly 34 includes a filter screen bracket 342 disposed in the humidifying chamber 3, a filter screen 341 joined to the filter screen bracket 342 and a drip tray 343, and a water pump 33 for transporting the water in the water tank 32 to the drip tray 343; the drip tray 343 is located above the filter screen 341 and is configured to be able to water the filter screen 341 evenly; a switch panel 45 is provided on the side wall of the fan assembly 4, and the switch panel 45 is provided with adjustment buttons in various modes. The fan assembly 4 is configured to be able to drive air to flow through the filter screen 341 to humidify the air. In this embodiment, the water tank 2 and the humidifying chamber 3 are separated, which can prevent the water droplets on the filter screen 341 from dripping back into the water tank 2 during the operation of the humidifier, causing secondary pollution to the water in the water tank 2, and the water in the water tank 2 can remain clean for a long time.

[0035] Referring to Figure 2 , Figure 3 and Figure 4 As shown, the filter screen 341 is joined to the filter screen bracket 342 and is configured not to immerse in the water in the water tank. The filter screen 341 is suspended above the water tank 32 through the filter screen bracket 342, which can prevent the filter screen 341 from being soaked in water for a long time, breeding bacteria, affecting human health, and the service life of the filter screen 341. The filter screen bracket 342, the filter screen 341 and the drip tray 343 are all configured as annular structures, and the axial direction of the annular structure is longitudinally disposed in the humidifying chamber 3; among them, the drip tray 343 is connected to the top of the filter screen bracket 342, the filter screen 341 is sleeved on the side wall of the filter screen bracket 342, and the drip tray 343 and the filter screen bracket 342 are combined by a snap button, which is convenient for users to disassemble, wash and replace.

By means of overflow in the water diversion channel, water can flow into the water dripping channel evenly, and then drip through the water dripping holes in the water dripping channel, which can moisten the filter screen more evenly, preventing water from dripping when it is pumped into the water dripping tray 343, resulting in less water flow reaching one end of the water dripping tray 343 far from the water inlet, and uneven wetting of the filter screen near and far from the water inlet, affecting the humidification efficiency.

[0037] Specifically, a diversion pipe 3421 communicating with the water pump 33 is arranged on the filter screen support 342. A second water outlet 3431 communicating with the diversion pipe 3421 is arranged in the water diversion channel 3433. A plurality of overflow grooves 3435 are arranged on the dam between the water diversion channel 3433 and the water dripping channel 3434. The water in the water tank 32 is pumped by the water pump 33 to the diversion pipe 3421 and enters the water diversion channel 3433 from the second water inlet 3431. After the water in the water diversion channel 3433 fills up to the bottom of the overflow groove 3435, it overflows along the overflow groove 3435 into the water dripping channel 3434. Among them, the plurality of overflow grooves 3435 are arranged at equal intervals, and the position of the overflow groove 3435 near the second water outlet 3431 is higher than that of the overflow groove far from the second water outlet 3431, so as to prevent the water flow from impacting the side wall when flowing out from the second water outlet 3431, resulting in the water flow flowing out from the overflow groove 3435 near the second water outlet 3431 in advance and not filling the entire water diversion channel 3433.

[0038] Specifically, two circles of water dripping holes 3432 arranged at intervals are arranged in the water dripping channel 3434. The two circles of water dripping holes 3432 arranged at intervals are arranged staggeredly, so that the water in the water dripping tray 343 can drip evenly. A water guiding groove 3436 is arranged on the water dripping channel 3434. The water dripping holes 3432 are located in the water guiding groove 3436. Each overflow groove 3435 corresponds to three water dripping holes 3432, and the three water dripping holes 3432 are distributed in a triangle. An inlet baffle 3437 is arranged above the second water outlet 3431 in the water diversion channel 3433 to prevent the water flow from impacting the upper fan assembly 4 when flowing out from the second water outlet 3431 and affecting the operation of the fan.

[0039] Refer to Figure 7 and Figure 8As shown in the figure, the fan assembly 4 includes a housing 41 and a fan 42. An air outlet 413 is provided at the top of the housing 41. The fan 42 is placed inside the housing 41 and is used to enable air to enter the humidifying chamber 3 from the first air inlet 31, pass through the wetted filter screen 341, and then flow out of the air outlet 413 with water vapor, thereby achieving fogless humidification in the room. A second air inlet 411 and a third air inlet 412 are provided at the lower end of one side of the housing 41. A Y-shaped air path 43 is provided inside the fan assembly 4. The two branches of the Y-shaped air path 43 are respectively communicated with the second air inlet 411 and the third air inlet 412, and an aromatherapy device 431 and a temperature and humidity detection device 432 are respectively provided on the two branches. Aromatherapy materials, such as essential oils, can be added to the aromatherapy device 431. After the fan is started, the indoor air can enter the two branches of the Y-shaped air path 43 from the second air inlet 411 and the third air inlet 412 respectively, flow out from the lower main path of the Y-shaped air path, and then be discharged into the room from the air outlet at the top of the fan assembly 4. The temperature and humidity detection device 432 on the branch can detect and display the indoor temperature and humidity in real time. The aromatherapy materials of the aromatherapy device 431 on the other branch volatilize, and while humidifying, the room can be aromatized.

[0040] Refer to Figure 2 、 Figure 5 and Figure 6 As shown in the figure, an antibacterial filter box 24 is provided on the first water outlet 22 of the water tank 2.

A water outlet hole adapted to the first water outlet 22 is provided at the bottom of the filter paper box 242, so that water can enter the filter paper box 242 from the water inlet holes 243, be filtered by the filter paper in the box, and then enter the water tank 32 through the water channel 21. The silver ion antibacterial box 241 can prevent the water in the water tank from deteriorating for a long time. The filter paper box 242 can filter out the impurity precipitation in the water, prevent the impurity precipitation in the water from being carried to the filter screen and adhering to the filter screen, and breeding bacteria.

[0041] Refer to Figure 6 As shown in the figure, a sterilization device 322 is provided in the water tank 32. The sterilization device 322 can use a water electrolysis ozone sterilization device to regularly sterilize the water in the water tank 32. A groove is provided at the bottom of the water tank 32.
