Description

Technical Field

[0001] This application relates to the field of humidifier filter technology, and more particularly to a humidifier filter structure. Background Technology

[0002] Humidifiers, as a type of household appliance that can regulate air humidity, are widely used in homes, offices and other places.

[0003] However, most existing humidifiers use a single-function filter structure, which can only achieve basic humidification and cannot effectively filter pollutants such as dust and pollen from the air. Due to the lack of an effective filtration mechanism, pollutants in the air will spread during the humidification process, causing secondary pollution and affecting the user's health. Utility Model Content

[0004] This application provides a humidifier filter structure to solve the technical problem that traditional filter structures lack air purification capabilities.

[0005] This application provides a humidifier filter structure, including:

[0006] A filter support has at least one air inlet on its side wall, and the air inlet is provided with a first mounting groove and a second mounting groove in sequence along the airflow direction;

[0007] A purification filter is detachably embedded in the first mounting slot to filter air pollutants entering the humidifier;

[0008] A humidifying filter is detachably embedded in the second mounting slot for humidifying the filtered air.

[0009] In one possible implementation, four air inlets are provided, and the four air inlets are evenly distributed along the circumference of the filter support.

[0010] In one possible implementation, the first mounting slot includes:

[0011] The first tank is horizontally positioned at the bottom of the filter support;

[0012] Two second grooves extend vertically upward from both ends of the first groove, forming a U-shaped snap-fit ​​structure;

[0013] The bottom and sides of the purification filter are respectively embedded in the first tank and the two second tanks.

[0014] In one possible implementation, the second mounting slot includes:

[0015] The third tank is horizontally positioned at the bottom of the filter support;

[0016] Two fourth grooves extend vertically upward from both ends of the third groove, forming a U-shaped snap-fit ​​structure;

[0017] The bottom and sides of the humidifying filter are respectively embedded in the third tank and the two fourth tanks.

[0018] In one possible implementation, the bottom of the filter support is provided with a water collection tank, and the bottom wall of the filter support is inclined towards the water collection tank from the side closest to the third tank.

[0019] In one possible implementation, the two opposite walls of the third tank are provided with a plurality of spaced-apart water outlets.

[0020] In one possible implementation, a gap exists between the first tank and the third tank, and the bottom of the gap forms a guide surface that slopes from the first tank to the third tank.

[0021] In one possible implementation, a support plate is provided between the two walls of the second tank near the fourth tank.

[0022] The technical solutions provided in this application have the following advantages compared with the prior art:

[0023] The humidifier filter structure provided in this application embodiment has at least one air inlet on the side wall of the filter support, with a first mounting slot and a second mounting slot sequentially arranged along the airflow direction. When the humidifier is running, outside air enters through the air inlet, first passing through the first mounting slot, where a detachable purifying filter filters out pollutants such as dust and pollen. The clean air then enters the second mounting slot, where it is humidified by the detachable humidifying filter, and finally the humidified air is released into the room. This application integrates purification and humidification functions into the same filter structure, and the separate mounting slots allow for independent purification and humidification steps, ensuring that the air is purified before humidification, preventing pollutants from spreading into the air with the water mist, and effectively improving indoor air quality. Furthermore, both the purifying and humidifying filters are detachable, allowing users to easily replace or clean them individually according to usage, reducing operating costs, improving maintenance convenience, and extending filter lifespan.

[0032] 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.

For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The humidifier filter structure may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in this text will be interpreted accordingly.

[0035] In order to solve the technical problem that the filter structure in the prior art lacks air purification, this application provides a humidifier filter structure.

[0036] Figure 1 and Figure 2 A humidifier filter structure is provided as an embodiment of this application. For better description, Figure 1 One of the air inlets conceals the purification filter 2 and the humidification filter 3. The humidifier filter structure of this application includes:

[0037] The filter support 1 has at least one air inlet 103 on its side wall. The air inlet 103 is provided with a first mounting groove 101 and a second mounting groove 102 in sequence along the airflow direction.

[0038] The purification filter 2 is detachably embedded in the first mounting groove 101 and is used to filter air pollutants entering the humidifier;

[0039] The humidifying filter 3 is detachably embedded in the second mounting slot 102 and is used to humidify the filtered air.

[0040] In the above technical solution, when the humidifier is turned on, external air is drawn in from the air inlet 103 by a fan and other power devices. The air first reaches the first mounting slot 101, where the detachable and embedded purification filter 2 quickly takes effect, intercepting and adsorbing various pollutants such as dust and pollen in the air, thus achieving preliminary air purification.

[0041] The purified air continues to move along the airflow direction and enters the second mounting slot 102. The humidifying filter 3 embedded here starts to work, humidifying the purified air to a suitable humidity level, and finally releasing the humidified air into the indoor environment.

[0042] Understandably, this application rationally separates the purification and humidification functions by sequentially setting a first mounting slot 101 and a second mounting slot 102 along the airflow direction at the air inlet 103. This design ensures that the air is purified first to remove pollutants before humidification, avoiding the problem of pollutants spreading into the air with water mist in traditional humidifiers due to a lack of purification function. This significantly improves indoor air quality and provides users with a healthier and more comfortable breathing environment.

[0043] Meanwhile, both the purification filter 2 and the humidifying filter 3 are detachably embedded in their respective mounting slots. This design allows users to easily and quickly remove the filters from their mounting slots for cleaning, replacement, or other maintenance operations, depending on their actual usage. For example, if the purification filter 2's purification effect decreases due to the adsorption of a large amount of pollutants, or the humidifying filter 3's performance deteriorates due to long-term use, the filters can be easily removed. This convenient maintenance method not only reduces operating costs and extends the filter's lifespan but also ensures that the humidifier always maintains good working condition, providing users with continuous and stable humidification and purification effects.

[0044] In one possible implementation, four air inlets 103 are provided, evenly distributed around the circumference of the filter support 1. When the humidifier is started, the fan operates to generate suction, driving external air to enter simultaneously through the four evenly distributed air inlets 103 around the circumference of the filter support 1. The four air inlets 103 form a multi-channel air intake pattern, allowing air to converge into the interior of the filter support 1 from various directions.

[0045] Understandably, the simultaneous intake of air through four inlets 103 significantly increases the surface area of ​​the airflow path into the humidifier, resulting in a substantial increase in air volume compared to a single inlet 103. Within the same timeframe, more air can enter the humidifier for purification and humidification, thereby accelerating indoor air circulation, rapidly increasing indoor humidity and purification levels, and allowing users to enjoy a comfortable and healthy indoor environment more quickly.

[0046] It should be noted that the angle between two adjacent air inlets 103 is 90°. This design ensures that the humidifier can draw in air regardless of its location in the room, guaranteeing stable and efficient operation in various environments. This expands the humidifier's applicability and enhances its market competitiveness.

[0047] Please refer to this again. Figure 1 In one possible implementation, the first mounting slot 101 includes:

[0048] The first tank 1011 is horizontally positioned at the bottom of the filter support 1;

[0049] Two second grooves 1012 extend vertically upward from both ends of the first groove 1011 to form a U-shaped snap-fit ​​structure;

[0050] The bottom and sides of the purification filter 2 are respectively embedded in the first groove 1011 and the two second grooves 1012.

[0051] The U-shaped snap-fit ​​structure provides three-sided support (bottom and sides) for the purification filter 2, greatly enhancing the stability of the filter installation. Even during long-term operation of the humidifier, facing continuous airflow impact and possible slight vibrations, the purification filter 2 can always remain in the correct position, ensuring stable purification function and avoiding problems such as air leakage or reduced purification effect due to filter displacement.

[0052] This snap-fit ​​structure ensures installation stability while also prioritizing user convenience. Specifically, when the purification filter 2 needs cleaning or replacement due to excessive adsorption of pollutants, the user simply needs to gently lift the filter 2 upwards to easily remove it from the U-shaped snap-fit ​​structure. The operation is simple and quick, requiring no complicated tools or professional assistance, thus reducing user costs and maintenance difficulties.

[0053] Meanwhile, the second mounting slot 102 includes:

[0054] The third tank 1021 is horizontally set at the bottom of the filter support 1;

[0055] Two fourth grooves 1022 extend vertically upward from both ends of the third groove 1021 to form a U-shaped snap-fit ​​structure;

[0056] The bottom and sides of the humidifying filter 3 are respectively embedded in the third groove 1021 and the two fourth grooves 1022.

[0057] The third groove 1021, horizontally arranged at the bottom of the filter support 1, provides a stable support platform for the bottom of the humidifying filter 3, ensuring its secure placement. Two fourth grooves 1022, extending vertically upwards from both ends of the third groove 1021, together with the third groove 1021, form a U-shaped snap-fit ​​structure. During installation, the bottom of the humidifying filter 3 is embedded in the third groove 1021, and the sides are embedded in the corresponding fourth grooves 1022, forming a stable installation. When the humidifying filter 3 experiences performance degradation due to prolonged use (such as insufficient humidification or scale buildup on the filter surface) or requires cleaning, the user can easily detach it from the U-shaped snap-fit ​​structure by gently lifting it upwards, without the need for specialized tools, facilitating cleaning, replacement, and other maintenance. This convenient maintenance method not only reduces user costs but also extends the lifespan of the humidifying filter 3 and minimizes equipment downtime caused by filter problems.

[0058] Please refer to this again. Figure 2 In one possible implementation, the bottom of the filter support 1 is provided with a water collection tank 104, and the bottom wall of the filter support 1 is inclined towards the water collection tank 104 from the side near the third tank 1021.

[0059] During humidification, the humidifying filter 3 continuously absorbs moisture and delivers humidified air into the room through evaporation. However, some water inevitably remains unevaporated during humidification, such as water droplets dripping from the surface of the humidifying filter 3, water overflowing after the filter becomes saturated, or water that detaches from the filter due to airflow disturbances. This excess water drips to the bottom of the filter support 1. Because the bottom wall of the filter support 1 is inclined towards the water collection tank 104 from the side closest to the third tank 1021, water flows automatically towards the water collection tank 104 under gravity. Ultimately, this water collects in the water collection tank 104 and is temporarily stored, preventing it from accumulating randomly at the bottom of the filter support 1.

[0060] This application, through the design of the water collection tank 104, can promptly collect excess water, effectively preventing water from accumulating at the bottom of the filter support 1 for extended periods. Accumulated water easily breeds bacteria, mold, and other microorganisms, not only producing unpleasant odors but also potentially spreading into the indoor air with the humidifier's airflow, harming human health. Furthermore, accumulated water can corrode metal or plastic components such as the filter support 1, shortening the equipment's lifespan. The water collection tank and sloping bottom wall effectively solve these problems, ensuring a clean internal environment for the humidifier and the safety of the equipment.

[0061] During use, users can choose to empty the water in the water collection tank 104 or reuse it (by recycling it into the water storage tank) depending on the actual situation. For example, a filter cotton can be installed above the water collection tank, and the water filtered by the filter cotton can be recycled into the water tank for secondary use.

[0062] Please refer to this again. Figure 1 In one possible implementation, the two opposite walls of the third tank 1021 are provided with a plurality of spaced-apart water outlets 1021a.

[0063] During the operation of the humidifier, after the humidifying filter 3 absorbs water, some of the excess water will be released from the filter and flow into the third tank 1021 located below it. Since the two opposite tank walls of the third tank 1021 are provided with multiple spaced water outlets 1021a, as the water level in the tank gradually rises, water will be discharged through these water outlets 1021a.

[0064] Specifically, the spaced outlets 1021a allow the water flow to be dispersed, preventing excessive local water flow due to concentrated drainage. As water continuously seeps out from the humidifying filter 3 and enters the third tank 1021, the outlets 1021a continuously guide the water to the water collection tank 104 at the bottom of the filter support 1, ensuring that no water accumulates in the third tank 1021 and maintaining a relatively dry and stable water level within the tank.

[0065] Please refer to this again. Figure 2 In one possible implementation, there is a gap between the first tank 1011 and the third tank 1021, and the bottom of the gap forms a guide surface 105 that slopes from the first tank 1011 to the third tank 1021.

[0066] When moisture accumulates in the third tank 1021 (e.g., the humidifying filter 3 drips a large amount of water, or the third tank 1021 has limited drainage capacity, resulting in a small amount of residual water), due to the gap between the first tank 1011 and the third tank 1021, excess water will not enter the purification filter 2. At the bottom of the gap, a guide surface 105 is formed that slopes from the first tank 1011 to the third tank 1021. Under the action of gravity, the accumulated water will automatically flow along the inclined guide surface 105 to the third tank 1021, and then enter the third tank 1021 through the outlet 1021a.

[0067] After entering the third tank 1021, the water will be further discharged to the designated area such as the water collection tank 104 through the outlet 1021a on another tank wall of the third tank 1021.

[0068] Understandably, the design of the inclined guide surface 105 provides a clear flow direction for water that may accumulate in the gap between the first tank 1011 and the third tank 1021, preventing water from accumulating randomly in the third tank 1021 and its surrounding area. Even if a small amount of water accumulates in the gap between the first tank 1011 and the third tank 1021 due to special circumstances, it can be quickly guided to the third tank 1021 and discharged, effectively preventing water accumulation from causing immersion, corrosion, or other damage to components such as the purification filter 2 and the filter support 1, ensuring the normal operation of the purification function and the service life of the equipment.

[0069] In one possible implementation, a support plate 106 is provided between the two walls of the second tank 1012 near the fourth tank 1022. When the humidifier is started, external air rushes in from the air inlet 103 under the action of a power device such as a fan. At this time, the air first comes into contact with the purification filter 2. Since the airflow has a certain kinetic energy, it will generate a thrust on the purification filter 2 toward the humidification filter 3. The support plate 106 can prevent the purification filter 2 from detaching from the second mounting slot 102 due to the force.

[0070] It should be noted that the end of the humidifying filter 3 away from the third tank 1021 can be inserted into the limiting groove of the spray component 4 to limit the humidifying filter 3, while facilitating the spray holes on the spray component 4 to spray water onto the humidifying filter 3.
