Abstract
Description
Technical Field
[0001] This application relates to the field of humidifier technology, and more particularly to a filter structure for a humidifier. Background Technology
[0002] With the improvement of people's living standards, humidifiers have become an important device for improving indoor air dryness. Most humidifiers on the market currently use the evaporative humidification principle, which involves absorbing moisture through a humidifying filter and then using airflow to evaporate the moisture, thereby achieving the effect of humidifying the air. However, this humidification method has the following technical problems in practical use:
[0003] While humidifier filters absorb moisture, they also trap suspended particles such as dust and hair from the air. When the water pump sprays water onto the filter, these contaminants are washed off and enter the water tank with the returning water, causing water contamination. Long-term accumulation not only produces limescale but can also breed bacteria, affecting the hygiene of the humidifier. Utility Model Content
[0004] This application provides a filter structure for a humidifier to solve the technical problem that contaminants attached to the humidifier filter screen enter the water tank with the return water, causing water quality pollution in the tank.
[0005] This application provides a filter structure for a humidifier, including a bracket, wherein at least one mounting groove is provided on the circumferential sidewall of the bracket, and the mounting groove is used for detachably installing a humidifier filter.
[0006] The mounting groove has several flow guiding notches on its groove wall;
[0007] A water collection tank is located at the bottom of the bracket and is connected to the water tank of the humidifier;
[0008] The opening of the flow guide notch faces the water collection tank, and a filter is provided between the flow guide notch and the water collection tank to filter the liquid flowing from the flow guide notch to the water collection tank.
[0009] In one possible implementation, the bottom wall of the bracket extends obliquely from one end near the mounting groove toward the water collection tank, forming a guide slope.
[0010] In one possible implementation, at least one overflow hole is provided between the flow guide notch and the filter, and the overflow hole is in communication with the water tank.
[0011] In one possible implementation, there are four overflow holes, which are respectively located at the four corners of the bracket.
[0012] In one possible implementation, the bracket is provided with a limiting groove, and the filter is disposed within the limiting groove.
[0013] In one possible implementation, the limiting groove is provided with a plurality of drainage holes, which are connected to the water collection tank.
[0014] In one possible implementation, the bottom wall of the water collection trough is inclined toward the water tank.
[0015] In one possible implementation, the flow guide notches are arranged at equal intervals on the wall of the mounting groove.
[0016] The technical solutions provided in this application have the following advantages compared with the prior art:
[0017] This application provides a humidifier filter structure. A humidifying filter screen is installed in a mounting groove on the circumferential side wall of a support frame. During humidifier operation, the filter screen absorbs and evaporates moisture to achieve humidification. When a water pump sprays water onto the filter screen, suspended particulate contaminants such as dust and hair adsorbed on the screen are washed off and enter the mounting groove with the returning water. A guide notch on the groove wall discharges the contaminant-containing returning water into a collection tank. A filter located between the guide notch and the collection tank filters the returning water, removing contaminants. The filtered water flows into the collection tank, which is connected to the humidifier's water tank, and the water then flows back to the water tank.
[0018] This application solves the problem of water pollution in the water tank of traditional humidifiers by filtering out pollutants in the return water through a filter, reducing scale formation and bacterial growth, and improving the hygiene of the humidifier. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] To address the technical problem in existing technologies where contaminants adhering to the humidification filter enter the water tank with the return water, leading to water quality pollution in the tank.
[0032] Figures 1 to 3 A humidifier filter structure provided in this application includes a bracket 1. At least one mounting groove 101 is provided on the circumferential side wall of the bracket 1. The mounting groove 101 is used for detachably mounting a humidifier filter 102.
[0033] The groove wall of the mounting groove 101 is provided with several flow guiding notches 1011;
[0034] A water collection tank 103 is located at the bottom of the bracket 1 and is connected to the water tank of the humidifier (not shown in the attached drawing);
[0035] The opening of the flow guide notch 1011 faces the water collection tank 103. A filter 2 is provided between the flow guide notch 1011 and the water collection tank 103 to filter the liquid flowing from the flow guide notch 1011 to the water collection tank 103.
[0036] In the above technical solution, during the operation of the humidifier (not shown in the attached drawings), the humidifying filter 102 is installed in the mounting groove 101 on the circumferential side wall of the bracket 1, utilizing its adsorption properties to absorb moisture while simultaneously intercepting suspended particles such as dust and hair in the air. When the water pump (not shown in the attached drawings) sprays water onto the humidifying filter 102, the contaminants attached to the humidifying filter 102 are washed off, forming return water containing contaminants.
[0037] After the return water enters the installation tank 101, it flows out along the guide notch 1011 on the tank wall, which faces the water collection tank 103. During the flow of the return water from the guide notch 1011 to the water collection tank 103, it passes through the filter 2 located between the two. The filter 2 intercepts suspended particulate pollutants such as dust and hair in the return water. The filtered water then flows into the water collection tank 103, which is connected to the humidifier's water tank. The filtered water ultimately returns to the water tank, completing the entire water cycle.
[0038] This application utilizes a filter 2 installed between the flow guide notch 1011 and the water collection tank 103 to intercept suspended particulate pollutants such as dust and hair in the return water, preventing these pollutants from entering the water tank, effectively purifying the water quality in the tank, reducing the risk of scale formation and bacterial growth, and providing users with a healthier and cleaner humidification environment.
[0039] Improved water quality in the tank reduces scale buildup, lowers the likelihood of bacterial growth, and enhances the hygiene of the humidifier, providing users with a healthier indoor humidification environment.
[0040] Meanwhile, the humidifying filter 102 can be detachably installed in the mounting slot 101, which makes it convenient for users to replace or clean the humidifying filter 102 regularly, ensuring the filtration effect and humidification performance of the humidifying filter 102 and extending the service life of the humidifier.
[0041] It should be noted that the bottom wall of the bracket 1 extends at an angle from the end near the mounting groove 101 toward the water collection tank 103, forming a guide slope. During the operation of the humidifier, the water pump sprays water onto the humidifying filter 102, washing away dust, hair, and other contaminants adsorbed on the filter 102. The return water containing contaminants flows out through the guide opening 1011 in the wall of the mounting groove 101 and then flows toward the bottom wall of the bracket 1. Since the bottom wall of the bracket 1 extends at an angle from the end near the mounting groove 101 toward the water collection tank 103, forming a guide slope, the return water will naturally flow toward the water collection tank 103 under the action of gravity along this guide slope.
[0042] In other words, the guide slope provides a clear flow direction for the return water, and the water can flow smoothly and quickly to the water collection tank 103 by using gravity. This avoids water accumulation in local areas of the bottom wall of the support 1 and effectively prevents water overflow or water accumulation from damaging other components inside the humidifier due to poor water flow.
[0043] The fast-flowing water can enter the subsequent filtration stage more promptly, enabling filter 2 to filter pollutants in the return water in a timely manner. This reduces the time that pollutants stay on the bottom wall of support 1, lowers the risk of re-contamination, and thus improves the efficiency of the entire filtration structure in treating return water.
[0044] Please refer to Figure 1 and Figure 3 In one possible implementation, at least one overflow hole 104 is provided between the flow guide notch 1011 and the filter 2, and the overflow hole 104 is connected to the water tank. Since at least one overflow hole 104 is provided between the flow guide notch 1011 and the filter 2, and the overflow hole 104 is connected to the water tank, when the filter 2 is blocked or too much water flows out from the flow guide notch 1011, the excess water will flow directly into the water tank through the overflow hole 104, preventing the water in the collection tank 103 from continuing to accumulate.
[0045] Understandably, the overflow hole 104 provides an additional drainage channel for the water collection tank 103. When the filter 2 is clogged or too much water flows out from the guide notch 1011, the overflow hole 104 can drain the excess water in time, preventing water from overflowing into other parts of the humidifier or the external environment, avoiding problems such as short circuits and equipment damage that may be caused by water overflow, and ensuring the safe operation of the humidifier.
[0046] In one possible implementation, there are four overflow holes 104, each located at one of the four corners of the bracket 1. The simultaneous operation of all four overflow holes 104 significantly increases the total drainage area, thereby enhancing drainage capacity. In the event of an abnormally high water volume, excess water can be drained more quickly, effectively preventing overflow and ensuring the stable operation of the humidifier's internal water circulation system.
[0047] Please refer to Figure 2 In one possible implementation, the bracket 1 is provided with a limiting groove 105, and the filter 2 is disposed within the limiting groove 105. When installing the filter 2, the filter 2 is placed within the limiting groove 105. The shape and size of the limiting groove 105 match the filter 2, thus fixing and positioning the filter 2. During the operation of the humidifier, the return water flows out from the guide notch 1011 and flows along a preset path to the filter 2. Since the filter 2 is stably disposed within the limiting groove 105, it can be ensured that the return water always passes accurately through the filter 2 for filtration. The filtered water then flows into the water collection tank 103 and finally returns to the water tank.
[0048] In other words, the limiting groove 105 can accurately position the filter 2, preventing it from shifting or shaking during use. This ensures that the return water passes through the filter 2 evenly and fully, allowing the filter 2 to effectively intercept suspended particulate pollutants such as dust and hair in the return water, ensuring the stability and reliability of the filtration effect, and thus maintaining the cleanliness of the water in the tank.
[0049] Meanwhile, the limiting groove 105 is provided with several drain holes 1051, which are connected to the water collection tank 103. The filtered water will accumulate in the limiting groove 105. Since the limiting groove 105 is provided with several drain holes 1051 and the drain holes 1051 are connected to the water collection tank 103, the water accumulated in the limiting groove 105 will flow into the water collection tank 103 through these drain holes 1051 under the action of gravity, and finally flow back to the water tank to complete the water circulation.
[0050] Understandably, the drain hole 1051 is designed to promptly drain the filtered water from the limiting groove 105, preventing water from accumulating within it. This helps maintain the normal operation of the filter structure, preventing the filter 2 from being submerged in water for too long due to water accumulation, which would affect the filtration effect. It also prevents water from overflowing the limiting groove 105 and damaging other components inside the humidifier.
[0051] In one possible implementation, the bottom wall of the water collection tank 103 is inclined toward the water tank. The inclined bottom wall provides a clear flow direction for the water, allowing the water to flow into the water tank quickly and smoothly using gravity. Compared to a horizontal bottom wall, this reduces the residence time of the water in the collection tank and improves the efficiency of water circulation.
[0052] Meanwhile, the sloping bottom design effectively prevents water accumulation in the water collection tank 103. If the bottom wall were horizontal, some water might remain in the water collection tank 103 when the water flow is obstructed, which could easily lead to bacterial growth and scale buildup over time. The sloping bottom wall, however, ensures complete drainage, reducing the risk of water accumulation and maintaining a clean and hygienic internal environment for the humidifier.
[0053] In one possible implementation, the guide notches 1011 are arranged at equal intervals on the wall of the mounting groove 101. The equally spaced guide notches 1011 ensure that the return water is evenly distributed and flows out within the mounting groove 101, avoiding localized water concentration or obstruction. This allows the return water to flow more evenly to the filter 2, enabling the filter 2 to fully perform its filtration function, improving the interception efficiency of pollutants such as dust and hair in the return water, thereby enhancing the overall filtration performance of the filter structure.
[0054] For example, if the flow guide notches 1011 are not evenly arranged, excessive water flow in some areas may overload the filter 2 locally, while insufficient water flow in other areas will result in some areas of the filter 2 not being fully utilized, thus reducing filtration efficiency. The flow guide notches 1011 arranged at equal intervals can avoid this situation.
[0055] Uniformly discharged return water reduces the impact on subsequent filter structures and the water collection tank 103. Uneven water flow may cause localized excessively high water velocity, resulting in significant impact on the filter 2 and water collection tank 103, which may damage these components over time. The evenly spaced guide notches 1011 ensure a smooth and uniform water flow, reducing this impact risk and extending the equipment's lifespan.
