Description

Technical Field

[0001] This application relates to the technical field of filter screens, and particularly to a filter screen structure and a humidifier. Background Art

[0002] During the operation of a humidifier, as the core component directly contacting water and air, the filter screen is long-term exposed to an erosion environment of impurities such as water scale and dust. With the extension of the usage time, these impurities will continuously deposit on the surface of the filter screen, resulting in the blockage of the pores of the filter screen, not only reducing the humidification efficiency, but also possibly breeding bacteria and affecting the air quality. Therefore, it is necessary to regularly clean the filter screen.

[0003] However, currently, commercially available humidifiers generally adopt an integrated fixed design of the filter screen and the bracket. The filter screen cannot be detached separately, and it is difficult for users to thoroughly clean the inside and corners of the filter screen. The remaining water scale and stains will accelerate the aging of the filter screen. When the performance of the filter screen deteriorates, users must replace the entire filter screen assembly, which not only increases the usage cost but also causes waste of resources. Summary of the Invention

[0004] This application provides a filter screen structure and a humidifier to solve the technical problem that the filter screen in the prior art cannot be detached separately for cleaning.

[0005] In a first aspect, this application provides a filter screen structure applied to a humidifier. The humidifier includes a spraying member, and the filter screen structure includes:

[0006] A filter screen bracket, on which there are provided at least one installation groove, and each installation groove includes:

[0007] A first groove body, horizontally arranged at the bottom of the filter screen bracket;

[0008] Two second groove bodies, respectively vertically extending upward from both ends of the first groove body to form a U-shaped clamping structure;

[0009] A filter screen member, the bottom and both sides of which are respectively embedded in the first groove body and the two second groove bodies, and one end of the filter screen member away from the first groove body extends into the limiting groove of the spraying member.

[0010] In a possible embodiment, there are four installation grooves, and the four installation grooves are evenly arranged along the circumferential direction of the filter screen bracket, and the included angle formed by two adjacent installation grooves is 90°.

[0011] In a possible embodiment, the space formed between the four installation grooves constitutes an air flow channel for guiding the air flow through.

[0012] In a possible embodiment, the height of the first groove wall of the second groove body is smaller than the height of the second groove wall, and two adjacent first groove walls are connected to form a bearing boss for placing the spray element.

[0013] In a possible embodiment, a water collecting groove is provided at the bottom of the filter bracket, and the bottom wall of the filter bracket is inclined from a side close to the first groove body toward the water collecting groove.

[0014] In a possible embodiment, a groove wall of one side of the first groove body close to the water collecting groove is provided with a plurality of water outlets arranged at intervals.

[0015] In a second aspect, the present application provides a humidifier, including a spray element and the above-mentioned filter structure, wherein the spray element is provided with a limiting groove that cooperates with an extension portion of the filter element.

[0016] In a possible embodiment, a plurality of spray holes are provided on a side of the spray member facing away from the limiting groove, and water outlet directions of the spray holes are toward the filter member.

[0017] The above technical solution provided by the embodiment of the present application has the following advantages compared with the prior art:

[0018] The present application sets at least one mounting groove in the circumference of the filter support, and the mounting groove is composed of a horizontal first groove body and two second groove bodies extending vertically upward from both ends of the first groove body to form a U-shaped clamping structure. When the filter element is installed, its bottom is embedded in the first groove body, and the two second groove bodies are embedded on both sides to realize the positioning of the filter element in the horizontal direction and part of the vertical direction. The end of the filter element away from the first groove body extends into the limit groove of the spray element, and forms a plug-in fit with the limit groove on the spray element to complete the axial limit of the filter element, so that the filter element is firmly installed on the filter support. Through the above structure, the filter element can be removed from the filter support alone, which is convenient for users to clean the filter element comprehensively and thoroughly, and can effectively remove scale and stains inside and at the corners of the filter, reduce impurity residues, and extend the service life of the filter. When the performance of the filter deteriorates, only the filter element needs to be replaced, and there is no need to replace the entire filter assembly, which reduces the user's use cost and reduces resource waste.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0033] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0034] For ease of description, spatially relative relationship terms may be used in the text to describe the relative positional relationship or movement of one element or feature shown in the figure with respect to another element or feature. These relative relationship terms such as "inside", "outside", "inner side", "outer side", "below", "beneath", "above", "over", "front", "rear", etc. This spatially relative relationship term is intended to include different orientations of the filter structure during use or operation other than the orientation depicted in the figure. For example, if the position of the filter structure in the figure is flipped or its attitude changes or its motion state changes, then these directional indications will change accordingly. For example, an element described as "below other elements or features" or "beneath other elements or features" will subsequently be oriented as "above other elements or features" or "over other elements or features". Therefore, the exemplary term "below" may include both upper and lower orientations. The filter structure may be otherwise oriented (rotated 90 degrees or in other directions) and the spatially relative relationship descriptors used in the text are interpreted accordingly.

[0035] To solve the technical problem in the prior art that the filter cannot be disassembled and cleaned separately, the present application provides a filter structure and a humidifier, and the filter element can be separately disassembled from the filter bracket, which is convenient for users to clean the filter element comprehensively and thoroughly.

[0036] Figures 1 to 6 A filter structure provided by an embodiment of the present application includes:

[0037] A filter bracket 1, which is circumferentially provided with at least one installation groove 101, and each installation groove 101 includes:

[0038] A first groove body 1011, which is horizontally arranged at the bottom of the filter bracket 1;

[0039] Two second groove bodies 1012, which respectively extend vertically upward from both ends of the first groove body 1011 to form a U-shaped clamping structure;

[0040] A filter element 2, the bottom and both sides of which are respectively embedded in the first groove body 1011 and the two second groove bodies 1012, and one end of the filter element 2 away from the first groove body 1011 extends into the limiting groove 301 of the spraying member 3.

[0041] In the above technical solution, the filter screen support 1 serves as the basic structure for carrying the filter screen member 2, and the installation grooves 101 provided circumferentially thereon are the key parts for installing the filter screen member 2. Each installation groove 101 is composed of a horizontal first groove body 1011 and two second groove bodies 1012 extending vertically upward to form a U-shaped clamping structure. The first groove body 1011 is located at the bottom of the filter screen support 1, providing support and horizontal positioning for the bottom of the filter screen member 2; the two second groove bodies 1012 extend vertically upward from both ends of the first groove body 1011, limiting the filter screen member 2 from both sides to prevent the filter screen member 2 from swaying left and right in the horizontal direction.

[0042] When installing the filter screen member 2, embed its bottom into the first groove body 1011 so that the bottom of the filter screen member 2 remains stable under the support of the first groove body 1011. Then embed both sides of the filter screen member 2 into the two second groove bodies 1012 respectively, and use the U-shaped clamping structure to fix the filter screen member 2 in the horizontal direction, ensuring that the position of the filter screen member 2 on the filter screen support 1 is accurate and stable. After the filter screen member 2 is installed on the filter screen support 1, then install the spraying member 3 on the filter screen support 1 and make the top of the filter screen member 2 extend into its limiting groove 301. Through this plug-in fit, the filter screen member 2 is limited in the axial direction (i.e., the direction perpendicular to the bottom of the filter screen support 1), preventing the filter screen member 2 from moving up and down during operation due to water flow impact or air flow action.

[0043] It can be understood that the design of the U-shaped clamping structure enables the filter screen member 2 to be quickly and accurately installed on the filter screen support 1. The user only needs to correspondingly embed the bottom and both sides of the filter screen member 2 into the first groove body 1011 and the second groove bodies 1012, and then insert the top extension 201 into the limiting groove 301 of the spraying member 3 to complete the installation, which is simple and convenient to operate. When it is necessary to clean or replace the filter screen member 2, the user only needs to operate in the reverse direction. First, detach the spraying member 3 (the spraying member 3 is detachably arranged on the filter screen support 1) so that the top of the filter screen member 2 is released from the limitation of the limiting groove 301, and then take out the filter screen member 2 from the installation groove 101. No complex tools and steps are required, greatly improving the convenience of maintenance. Since the filter screen member 2 can be detached separately, when the filter screen performance deteriorates, the user only needs to replace the filter screen member 2 without replacing the entire filter screen assembly, reducing the replacement cost. It avoids the waste of resources caused by replacing the entire filter screen assembly, conforms to the environmental protection concept, and also reduces the user's usage cost.

[0044] Please refer to Figure 1 and Figure 2 , in a possible embodiment, there are four installation grooves 101, and the four installation grooves 101 are evenly arranged along the circumference of the filter screen support 1, and the included angle formed by two adjacent installation grooves 101 is 90°.

[0045] It can be understood that the four mounting grooves 101 are evenly distributed at 90° intervals in the circumferential direction of the filter screen bracket 1. When the four filter screen members 2 are respectively installed into the corresponding mounting grooves 101, they will form a filter and humidification area similar to a cylindrical shape around the center of the filter screen bracket 1. Two adjacent filter screen members 2 are perpendicular to each other in the horizontal direction and act on the passing air flow and water flow from four different directions. When the humidifier operates, air flows from all around to the area where the filter screen structure is located. Due to the uniform distribution of the four filter screen members 2, air can evenly enter the space between the filter screen members 2 from all directions. That is to say, the four filter screen members 2 greatly increase the contact area between air and water, and more air can come into contact with the wet filter screen members 2 and complete humidification at the same time, thus significantly improving the humidification efficiency.

[0046] In a possible embodiment, the space formed between the four mounting grooves 101 constitutes an air flow channel 102 for guiding the air flow through.

[0047] When the humidifier operates, the internal fan starts to generate a negative pressure environment. Under the action of the pressure difference, the outside air is sucked in from the air inlet of the humidifier. At this time, the air entering the humidifier first passes through the filter element. When the dry air passes through the filter screen member 2, the partial pressure of water vapor in the air is lower than the partial pressure of water vapor on the surface of the filter screen member 2. According to the diffusion principle, moisture will diffuse from the surface of the filter screen member 2 into the air, making the air moist. When the moist air flows out of the filter screen member 2, it will be guided along the direction of the air flow channel 102 to the air outlet of the humidifier.

[0048] Please refer to Figure 4 , in a possible embodiment, the height of the first groove wall 1012a of the second groove body 1012 is less than the height of the second groove wall 1012b, and two adjacent first groove walls 1012a are connected to form a bearing boss for placing the spraying member 3.

[0049] It can be understood that the bearing boss provides a reliable support platform for the spraying member 3, effectively resisting various external force interferences generated during the operation of the humidifier. Compared with the design without a specific support structure, the spraying member 3 is more stable on the bearing boss, avoiding problems such as uneven water spraying and water leakage caused by shaking or displacement, and improving the reliability and stability of the overall structure of the humidifier. In addition, when it is necessary to maintain, clean or replace the spraying member 3, since the spraying member 3 is removed from the bearing boss, after necessary operations, it is put back in place, without the need to perform large-scale disassembly of the entire filter screen bracket 1, saving maintenance time and effort.

[0050] In a possible embodiment, a water collecting tank 103 is provided at the bottom of the filter screen bracket 1, and the bottom wall of the filter screen bracket 1 is inclined from the side close to the first groove body 1011 towards the water collecting tank 103.

[0051] It can be understood that the bottom wall of the filter screen support 1 is not horizontal, but slopes from the side close to the first tank 1011 towards the water collecting tank 103. When the humidifier is operating, the spraying member 3 sprays water onto the filter screen member 2. Some of the water will naturally fall due to the action of gravity or drip from the wet filter screen member 2. These falling water droplets first contact the bottom wall of the filter screen support 1. Due to the inclination of the bottom wall, the water droplets will generate a downward sliding component force along the inclined direction, and thus flow along the inclined bottom wall towards the water collecting tank 103. The water collecting tank 103 has a relatively large volume and a suitable shape, capable of accommodating a certain amount of water, preventing excessive water accumulation on the filter screen support 1 and overflowing, which may affect the normal operation of the humidifier. In some humidifier designs, the water collected in the water collecting tank 103 can be re-transported to the spraying member 3 through a power device such as a water pump to achieve the recycling of water. When the humidifier detects that there is sufficient water in the water collecting tank 103, the water pump starts, pumps the water out of the water collecting tank 103, and transports it to the spraying member 3 through the necessary water pipelines, and sprays it onto the filter screen member 2 again, forming a complete water circulation system to improve the utilization rate of water resources.

[0052] Please refer to Figure 3 , in a possible embodiment, a plurality of spaced-apart water outlets 1011a are provided on the side wall of the first tank 1011 close to the water collecting tank 103.

[0053] During the operation of the humidifier, the spraying member 3 sprays water onto the filter screen member 2, and the water flow on the surface of the filter screen member 2 will flow down along its own structure and finally converge into the first tank 1011. The plurality of spaced-apart water outlets 1011a provided on the side wall of the first tank 1011 close to the water collecting tank 103 provide a discharge channel for the water collected in the first tank 1011. When the water level in the first tank 1011 rises to the height of the water outlets 1011a, the water will flow into the water collecting tank 103 through these water outlets 1011a under the action of its own gravity. Since the water outlets 1011a are spaced apart, the water flow will enter the water collecting tank 103 in a dispersed manner, avoiding excessive water flow impact or poor drainage caused by concentrated drainage.

[0054] Please refer to Figure 5 , the present application also provides a humidifier (not shown), including a spraying member 3 and the above-mentioned filter screen structure. The spraying member 3 is provided with a limiting groove 301 that cooperates with the extension portion 201 of the filter screen member 2. When assembling the humidifier, align the extension portion 201 of the filter screen member 2 with the limiting groove 301 of the spraying member 3. Due to the matching relationship of their shapes and sizes, the extension portion 201 can be smoothly inserted into the limiting groove 301.

[0055] In a possible embodiment, a plurality of spraying holes 302 are provided on the side of the spraying member 3 facing away from the limiting groove 301, and the water outlet direction of the spraying holes 302 faces the filter screen member 2.

[0056] After the humidifier is started, water is transported from a water source (such as a water tank) to the water channel inside the spraying member 3 via a power device such as a water pump. The water channel forms a specific water flow path inside the spraying member 3, guiding the water to the positions where each spraying hole 302 is located. Multiple spraying holes 302 work simultaneously to disperse the water flow into multiple fine water columns or water mists. These dispersed water flows can cover different areas of the filter member 2, avoiding the situation of uneven local wetting.

[0057] Specifically, the water sprayed from each spraying hole 302 forms a certain wetting area around it, and the wetting areas of multiple spraying holes 302 overlap with each other, so that the entire surface of the filter member 2 can be evenly wetted. The filter member 2 usually has a porous or fibrous structure. When the water sprayed from the spraying hole 302 contacts the surface of the filter member 2, the water will diffuse along the pores or fibers of the filter member 2. This diffusion effect further enhances the uniform distribution of water on the filter member 2, enabling the filter member to adsorb and retain water more fully, providing good conditions for subsequent water mist evaporation.
