Description

Technical Field

[0001] The utility model relates to an air humidifier product, in particular to a humidifier with an ionization sterilization function. Background Art

[0002] Evaporative humidifiers usually include a blower, a water storage tank, a filter element assembly, etc. The lower end of the filter element assembly is immersed in the water storage tank for wetting, and then the air is filtered and humidified by blowing and sucking air externally, so as to realize blowing wet and clean air flow into the room. However, affected by gravity and the water absorption capacity of the filter element, the wetting is uneven. Usually, the lower end of the filter element assembly is wet and the upper end is dry. To ensure the infiltration of the filter element assembly, it is necessary to always maintain the water level in the water storage tank, or make the filter element assembly longer so that its lower end can reach the bottom of the water storage tank. Obviously, the cost of such a scheme, whether it is the water replenishment cost or the cost of the filter element assembly, will be relatively high, and it is not environmentally friendly and energy-saving. At the same time, since the water body is stored in the water storage tank for a long time, bacteria are likely to breed, and the filter element will also breed bacteria when immersed in water for a long time, resulting in the fact that the wet air flow is actually not conducive to health, which is a common problem of humidifier products. Summary of the Utility Model

[0003] The utility model provides a humidifier with an ionization sterilization function to solve the problems of air filtration, wetting and sterilization. The specific technical means adopted are as follows:

[0004] A humidifier with an ionization sterilization function includes a housing.

[0019] The solution of the present application will be further described in conjunction with the accompanying drawings as follows:

[0020] Refer to the attached Figures 1 to 7 , a humidifier with an ionization sterilization function, including a housing 1, in which a blowing mechanism 2, a filter element module 3 and a water storage tank 4 are arranged from top to bottom. At the top of the housing 1, there is a water injection port 10, and the water injection port 10 communicates with the water storage tank 4 through a water injection channel 5. The filter element module 3 includes a filter element support 31 and a cylindrical filter element 32. The upper part of the filter element support 31 is provided with an annular water channel 311, and the bottom of the annular water channel 311 has a plurality of water drainage holes 312 facing the top of the cylindrical filter element 32. The top of the water storage tank 4 is provided with a return port 40, and a water pump 6 and a water pipe 61 for connecting the water pump 6 and the annular water channel 311 are arranged in the water storage tank 4. An electrolyzed water module 7 is also arranged in the water storage tank 4.

[0021] The top-watering method of this product is convenient for users to replenish water and eliminates the trouble of disassembling the water storage tank 4. The user only needs to pour an appropriate amount of water into the water injection port 10, and the water will automatically flow to the bottom water storage tank 4 under the action of gravity, making the water filling process easier and more interesting; the filter element adopts a top-down wetting structure, which not only wets sufficiently, evenly and quickly, but also does not need to consider the contact size between the filter element and the water storage tank like traditional products, relaxing the design limitations of the product structure, and the water tank capacity can be smaller, and the water replenishment amount can also be smaller. At the same time, considering that bacteria are likely to breed during the long-term storage of water, an electrolyzed water module is arranged in the water storage tank to generate hypochlorous acid and use its strong oxidizing property to sterilize the water body.

[0022] Among them, the working principle of the electrolyzed water module 7 is: electrolyzing the water body, chlorine ions are oxidized at the anode of the electrolyzed water module to generate chlorine gas, and the chlorine gas dissolves in water to generate hypochlorous acid and hydrochloric acid. When the strong oxidizing property of hypochlorous acid acts on the surface of bacteria, the amino acids in the bacteria are oxidized and decomposed, making them lose their activity.

[0023] Considering the sterilization requirement for filtered air, a UV lamp 8 is provided at the air inlet of the air blowing mechanism 2. When the air is wetted and filtered by the cylindrical filter element 32 and then subjected to secondary disinfection by the UV lamp 8, it has a better sterilization effect. Moreover, the irradiation of the UV lamp also inhibits the growth of bacteria on the cylindrical filter element under long-term wetting conditions. Specifically, an air inlet grid 21 is provided at the bottom of the air blowing mechanism 2, and a UV lamp slot 210 is provided in the middle of the air inlet grid 21. The UV lamp 8 is installed in the UV lamp slot 210 and faces the central channel of the cylindrical filter element 32. The UV lamp slot 210 is located at the central position of the air inlet grid 21 and is connected to the outer edge of the air inlet grid 21 through a side slot 211 for threading wires.

[0024] A water collecting tray 11 and a cover member 12 covering the water collecting tray 11 are provided at the top of the housing 1. An air outlet grid 13 is provided at the periphery of the water collecting tray 11. A concave water collecting groove 121 is provided on the cover member 12, and a water injection port 10 communicating with the water collecting tray 11 is provided in the water collecting groove 121. The bottom of the water collecting tray 11 is connected to the water injection channel 5, and a filter grid 122 is provided at the water injection port 10. The water injection channel 5 includes a first drainage section 51 extending from the bottom of the water collecting tray 11, a second drainage section 52 provided on the volute of the air blowing mechanism 2, and a third drainage section 53 provided on the filter element support 31. The first drainage section 51, the second drainage section 52, and the third drainage section 53 are sequentially butted. The above-mentioned water injection channel 5 adopts a three-section design, which is convenient for the forming, disassembly, and assembly of each component. As shown by the arrow in the attached Figure 7 figure, the user adds water to the water collecting groove 121, the water body flows into the water collecting tray 11 through the water injection port 10, and then flows into the water collecting groove 41 of the water storage tank 4 through the first drainage section 51, the second drainage section 52, and the third drainage section 53, and finally enters the water storage tank 4 through the return port 40.

[0025] A water collecting groove 41 is provided at the top of the water storage tank 4. The water collecting groove 41 has a return port 40 communicating with the inside of the water storage tank 4. The filter element support 31 is provided above the water collecting groove 41. The bottom end opening of the third drainage section 53 leads to the water collecting groove 41. The water drained from the filter element module 3 also drips into the water collecting groove 41 and enters the water storage tank 4 through the return port 40. Through the operation of the water pump 6, the water circulates through the filter element module 3 and the water storage tank 4. This top-down wetting structure achieves a continuous and sufficient wetting effect and also minimizes water consumption. Therefore, the water will stay in the water storage tank for a longer time, so electrolytic sterilization is more necessary.

[0026] With the top-down component layout, this product adopts a segmented electrical box structure, and corresponding electrical devices are respectively arranged in each segment, such as a power supply board, a sensor, a water level detection board, etc. Specifically, an electrical box assembly 9 is further arranged in the housing 1. The electrical box assembly includes an upper box assembly 91 integrated with the filter element bracket 31 and a lower box assembly 92 integrated with the water storage tank 4. The upper box assembly 91 and the lower box assembly 92 are plugged together through a coupler assembly 93. The coupler assembly 93 includes a coupler plug arranged at the bottom end of the upper box assembly 91 and a coupler socket arranged at the top end of the lower box assembly 92. The docking of the electrical circuit is realized through the coupler assembly 93. A temperature sensor is arranged in the upper box assembly 91, and a water level detection board is arranged in the lower box assembly 92, which can detect the water level in the water storage tank 4 so that the control display panel of the humidifier gives a water replenishment indication at low water level.

[0027] The above preferred implementation manners shall be regarded as examples of the implementation manners of the application solution of the present application. All technical deductions, substitutions, improvements, etc. that are identical, similar to or based on the application solution of the present application shall be regarded as the protection scope of this patent.
