[0028] The humidification component and electrical device provided in this application embodiment, in which the second support is in a first state and closed relative to the first support, with the filter and the evaporative cooling pad facing each other. Air can then pass through the filter, which captures dust, particles, and other pollutants, turning the airflow into clean air. This clean air then passes through the evaporative cooling pad, where moisture evaporates rapidly, increasing the humidity and resulting in high-humidity clean air. Alternatively, air can first pass through the evaporative cooling pad, where moisture evaporates rapidly, creating high-humidity air, which then passes through the filter to obtain high-humidity clean air, improving indoor air quality. In this process, the humidification component simultaneously purifies and humidifies the air, reducing the space occupied by multiple devices used at the same time, and lowering operating costs and complexity. By first filtering the air to become clean air before passing it through the evaporative cooling pad, pollutants in the air can be effectively reduced or prevented from adhering to the pad, greatly reducing the possibility of mold growth and ensuring user health. It also prevents mold spores from entering the water system of the electrical device with the moisture from the evaporative cooling pad and contaminating the water source.

[0029] The electrical device provided in this application includes the above-mentioned humidification component. After the air is purified by the filter and humidified by the wet curtain, high-humidity clean air can be obtained. Therefore, it naturally has the technical effects of the above-mentioned humidification component. Attached Figure Description

[0046] 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.

[0047] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0048] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. 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 device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0049] While some electrical appliances on the market offer humidification or purification functions, they are typically single-function and space-consuming, requiring users to purchase multiple devices to meet their needs, increasing costs and complexity. For example, if a user wants to use a humidifier or air cooler in a dry season or environment, the evaporative cooling pad will be directly exposed to the air. During operation, these appliances draw in large amounts of indoor air. Since indoor air contains dust, particles, and other pollutants, these pollutants adhere to the evaporative cooling pad. High humidity environments easily breed mold, bacteria, and other microorganisms. These microorganisms can grow and multiply on the filter under humid conditions, especially when the filter surface has dust, dirt, or other organic matter as a nutrient source, greatly increasing the likelihood of mold growth. Mold spores can then enter the air with the airflow, affecting the user's health. Furthermore, mold spores may enter the appliance's water system with the moisture, contaminating the water source.

[0050] To address the technical problems of existing humidifying or purifying electrical products having limited functionality, large space requirements, and the need for users to purchase multiple devices to meet their needs, which increases usage costs and complexity, this application provides a humidifying component and electrical device that simultaneously purifies and humidifies the air. This reduces the space occupied by multiple devices, lowers usage costs and complexity, and effectively reduces or prevents airborne pollutants from adhering to the evaporative cooling pad, greatly reducing the possibility of mold growth and thus ensuring user health. Furthermore, it prevents mold spores from entering the water system of the electrical device along with the moisture from the evaporative cooling pad and contaminating the water source.

[0051] Figure 1 and Figure 2A humidification assembly 1 provided in this application includes a first support 11 and a second support 13. A wet curtain 12 is disposed on the first support 11. The second support 13 is disposed on the first support 11 and a filter element 14 is disposed on the second support 13. The second support 13 has a first closed state relative to the first support 11. In the first state, air can be filtered by the filter element 14 and then pass through the wet curtain 12 to form high-humidity clean air; or, air can be humidified by the wet curtain 12 and then pass through the filter element 14 to form high-humidity clean air.

[0052] It should be noted that the evaporative cooling pad 12 can be made of a material with strong water absorption and high evaporation efficiency. Water, under the influence of gravity, permeates downwards along the surface of the cooling pad 12, forming a uniform water film. When air passes through the cooling pad 12, the water evaporates rapidly, turning the airflow into high-humidity air and increasing air humidity. The filter element 14 can be an air filter 141. When air passes through the filter element 14, dust, particles, and other pollutants in the air are captured by the air filter 141, turning the airflow into clean air and achieving the purpose of filtration. It is understandable that, as... Figure 2 As shown, the second support 13 is in the first state, closed relative to the first support 11. At this time, the filter element 14 and the evaporative cooling pad 12 are positioned facing each other. Air can then pass through the filter element 14, which captures dust, particles, and other pollutants, transforming the airflow into clean air. This clean air then passes through the evaporative cooling pad 12, where moisture evaporates rapidly, increasing the humidity and resulting in high-humidity clean air. Alternatively, air can first pass through the evaporative cooling pad 12, where moisture evaporates rapidly, creating high-humidity air. This high-humidity air then passes through the filter element 14, resulting in high-humidity clean air and improving indoor air quality. In this process, the humidification component 1 simultaneously purifies and humidifies the air, reducing the space occupied by multiple devices used simultaneously and lowering operating costs and complexity. The air is first filtered by the filter element 14 to become clean air before passing through the wet curtain 12. This can effectively reduce or prevent pollutants in the air from adhering to the wet curtain 12, greatly reducing the possibility of mold growth on the wet curtain 12, thus ensuring the health of users. At the same time, it can prevent mold spores from entering the water system of the electrical equipment 100 with the moisture from the wet curtain 12 and contaminating the water source.

[0053] The evaporative cooling pad 12 can be made of a material with high water absorption and evaporation efficiency, such as a high-absorption water-based wet film material. The wet film material uses a drip-permeable humidification method. Under the influence of gravity, water seeps downwards along the surface of the cooling pad 12 and is fully absorbed by the polymer wet film material. Due to the excellent water absorption of the wet film material, a uniform water film is formed. When air passes through the cooling pad 12, heat exchange occurs between the water and the air, and the moisture evaporates rapidly, making the airflow high-humidity air, thereby increasing the air humidity and achieving the purpose of humidification.

[0054] In one embodiment, such as Figure 3 As shown, the second bracket 13 is rotatably mounted on the first bracket 11, so that the second bracket 13 has a second state of being unfolded relative to the first bracket 11. The second bracket 13 includes a fixed end 131 and a moving end 132 disposed opposite to each other. The fixed end 131 of the second bracket 13 is rotatably connected to the first bracket 11. The moving end 132 of the second bracket 13 can rotate closer to the first bracket 11 to reach the first state under the action of an external force, or the moving end 132 of the second bracket 13 can rotate away from the first bracket 11 to reach the second state. It should be noted that the external force refers to the user's pushing force or the driving force of the driving component. For ease of explanation, the two sides in the vertical direction are referred to as up and down, respectively. Understandably, the moving end 132 of the second support 13 can be flipped downwards under external force, meaning the moving end 132 of the second support 13 can rotate close to the first support 11 to reach the first state. At this time, the wet curtain 12 and the filter element 14 are positioned facing each other, and air can pass through the filter element 14. The filter element 14 captures dust, particles, and other pollutants in the air, turning the airflow into clean air. Then, the clean air passes through the wet curtain 12, where the moisture evaporates rapidly, increasing the humidity in the clean air, thus obtaining high-humidity clean air. Of course, the air can also first pass through the wet curtain 12, where the moisture evaporates rapidly, turning the airflow into high-humidity air. The high-humidity air then passes through the filter element 14, thus obtaining high-humidity clean air. The moving end 132 of the second support 13 can be flipped upwards under external force, meaning the moving end 132 of the second support 13 can rotate close to the first support 11 to reach the second state. At this time, the second support 13 is unfolded relative to the first support 11, and the wet curtain 12 and the filter element 14 form an angle, providing sufficient operating space between them for convenient maintenance of the water system or replacement of the wet curtain 12.

[0055] In an optional embodiment, such as Figure 4 As shown, the first bracket 11 is provided with a first receiving cavity 111, and the evaporative cooling pad 12 is disposed within the first receiving cavity 111. The connection between the evaporative cooling pad 12 and the first bracket 11 can be fixed by means of locking, snap-fit ​​connection, adhesive connection, etc., and this application does not impose specific limitations here. For example, the bottom of the first bracket 11 is provided with a recessed groove, and one side of the evaporative cooling pad 12 can be embedded in the recessed groove, thereby limiting the position of the evaporative cooling pad 12 in the front-back direction and the vertical direction. The evaporative cooling pad 12 abuts against the inner sidewall of the first bracket 11, thereby limiting the position of the evaporative cooling pad 12 in the horizontal direction.

[0056] In an optional embodiment, such as Figure 5As shown, the second support 13 is provided with a second receiving cavity 133, and the filter element 14 is disposed within the second receiving cavity 133. The side of the second support 13 facing away from the first support 11 is called the front side, and the side of the second support 13 facing the first support 11 is called the back side. The front and back sides of the second support 13 may also be provided with transverse reinforcing ribs 134 and longitudinal reinforcing ribs 135. The two ends of the transverse reinforcing ribs 134 are respectively connected to the second support 13, and the two ends of the longitudinal reinforcing ribs 135 are respectively connected to the second support 13. The transverse reinforcing ribs 134 and longitudinal reinforcing ribs 135 not only improve the structural strength of the second support 13, but also provide support for the filter element 14.

[0057] In some embodiments, such as Figure 1 As shown, the orthographic projection of the filter element 14 on the vertical plane at least partially covers the orthographic projection of the evaporative cooling pad 12 on the vertical plane. It should be noted that the evaporative cooling pad 12 can be inclined relative to the vertical plane or parallel to the vertical plane; the filter element 14 can be inclined relative to the vertical plane or parallel to the vertical plane.

[0058] In a preferred embodiment, both the evaporative cooling pad 12 and the filter element 14 are parallel to the vertical plane, allowing water to penetrate downwards along the surface of the evaporative cooling pad 12 more quickly under gravity, forming a uniform water film. The orthographic projection of the filter element 14 on the vertical plane at least partially covers the orthographic projection of the evaporative cooling pad 12 on the vertical plane. It is understood that when the second support 13 is in the first state, the overlapping area of ​​the orthographic projections of the filter element 14 and the evaporative cooling pad 12 on the vertical plane ensures that the air can be simultaneously purified by the filter element 14 and humidified by the evaporative cooling pad 12, thereby obtaining high-humidity clean air, improving indoor air quality, and ensuring the user's health.

[0059] In a more preferred example, the orthographic projection of the filter element 14 on the vertical plane completely covers the orthographic projection of the evaporative cooling pad 12 on the vertical plane. When air forms an airflow under negative pressure, the airflow first passes through the filter element 14, which captures dust, particles, and other pollutants in the air, turning the airflow into clean air. Then, the clean air passes through the evaporative cooling pad 12, where moisture evaporates rapidly, increasing the humidity of the clean air and thus obtaining high-humidity clean air. In this way, the cleanliness of indoor air can be guaranteed, while effectively reducing or preventing pollutants in the air from adhering to the evaporative cooling pad 12, greatly reducing the possibility of mold growth on the evaporative cooling pad 12, further ensuring the health of users, and preventing mold spores from entering the water system of the electrical equipment 100 with the moisture from the evaporative cooling pad 12 and contaminating the water source.

[0060] The first support 11 can be configured as a square frame, or as a circular frame, or even as an irregularly shaped frame; this application does not impose specific limitations herein. For example, as... Figure 1 As shown, when the first support 11 is set as a square frame, the second support 13 can also be set as a square frame accordingly, so that the orthographic projection of the filter element 14 in the vertical direction covers as much as possible the orthographic projection of the wet curtain 12 in the vertical direction. Of course, the shape of the second support 13 may not match the shape of the first support 11.

[0061] In one embodiment, such as Figure 4 and Figure 6 As shown, a water pipe 15 is provided on the first support 11, and the outlet of the water pipe 15 is connected to the wet curtain 12 to provide water to the wet curtain 12. A mounting part 16 is provided on the fixed end 131 of the second support 13, and the mounting part 16 is rotatably connected to the water pipe 15 or the first support 11. To facilitate water immersion in the wet curtain 12, the water pipe 15 is preferably located at the top of the first support 11, and an outlet is provided at the bottom of the water pipe 15. Multiple outlets can be provided, allowing water to be delivered to the top of the wet curtain 12 through the outlets. Under the action of gravity, the water penetrates downwards along the surface of the wet curtain 12 and is fully absorbed by the polymer wet film material. Due to the excellent water absorption of the wet film material, a uniform water film is formed. When air passes through the wet curtain 12, the water and air exchange heat, and the water evaporates rapidly, making the airflow high-humidity air, thereby increasing the air humidity and achieving the purpose of humidification.

[0062] The mounting part 16 can be rotatably connected to the water pipe 15, and the mounting part 16 can also be rotatably connected to the first bracket 11. The moving end 132 of the second bracket 13 can rotate close to the first bracket 11 to reach the first state, so that the wet curtain 12 and the filter element 14 are set facing each other. The air can be purified by the filter element 14 to obtain clean air. Then, the clean air passes through the wet curtain 12 to increase the humidity in the clean air, thereby obtaining high humidity clean air. Alternatively, the moving end 132 of the second bracket 13 can rotate away from the first bracket 11 to reach the second state. At this time, the second bracket 13 is unfolded relative to the first bracket 11, and the wet curtain 12 and the filter element 14 form an angle. There is enough operating space between the two to facilitate the inspection and maintenance of the water system or the replacement of the wet curtain 12.

[0063] Of course, if the filter element 14 needs to be replaced, the mounting part 16 can also be removed from the water pipe 15 or the first bracket 11.

[0064] In some embodiments, such as Figure 7As shown, the mounting part 16 includes a hook 161, which includes a connected support section 1611 and a connecting section 1612. A first groove 1613 is provided on the side of the connecting section 1612 away from the support section 1611, and the first groove 1613 connects to the outer periphery of the water pipe 15. By engaging the first groove 1613 with the outer periphery of the water pipe 15, a rotatable connection between the mounting part 16 and the water pipe 15 can be achieved. When the user pulls the second bracket 13, causing the moving end 132 of the second bracket 13 to rotate upwards about the second water pipe axis, the moving end 132 of the second bracket 13 moves away from the first bracket 11 to reach a second state. Sufficient operating space exists between the first bracket 11 and the second bracket 13, facilitating the replacement of the wet curtain 12 or checking for blockages in the water system. When the user pulls the second bracket 13, causing the moving end 132 of the second bracket 13 to rotate downwards around the second water pipe axis, the moving end 132 of the second bracket 13 approaches the first bracket 11 and reaches the first state. At this time, air can pass through the filter element 14 and the wet curtain 12 in sequence, or air can pass through the wet curtain 12 and the filter element 14 in sequence, so as to simultaneously achieve the functions of filtration and humidification. Due to the support section 1611, in the first state, the side of the second bracket 13 facing the wet curtain 12 has a certain distance from the side of the wet curtain 12 facing the filter element 14, thereby avoiding interference between the filter element 14 and the wet curtain 12 during the rotation of the second bracket 13.

[0065] Optionally, the first groove 1613 can be configured as an arc shape, and the radius of curvature of the arc-shaped first groove 1613 is adapted to the radius of the water pipe 15 so as to stably attach the mounting part 16 to the water pipe 15. If the filter element 14 needs to be replaced, the mounting part 16 can also be removed from the water pipe 15.

[0066] Furthermore, the connection between the support section 1611 and the connecting section 1612 can be smoothly transitioned to avoid stress concentration at the connection between the support section 1611 and the connecting section 1612. At the same time, it can also prevent the connection between the support section 1611 and the connecting section 1612 from being too sharp and injuring the user, thereby improving the safety of using the humidification component 1.

[0067] In a preferred embodiment, such as Figure 4 and Figure 5As shown, multiple hooks 161 are provided, spaced apart. Multiple annular grooves 151 are provided on the outer periphery of the water pipe 15, and these grooves correspond one-to-one with the first grooves 1613 of the multiple hooks 161. Providing multiple hooks 161 connected to the water pipe 15 improves the stability of the connection between the hooks 161 and the water pipe 15, resulting in a more even distribution of force on the first support 11. When installing the second bracket 13, the first groove 1613 of the hook 161 is aligned with the annular groove 151 of the water pipe 15. The annular groove 151 serves a positioning function, facilitating alignment during installation and preventing the second bracket 13 from shifting horizontally relative to the first bracket 11. When the second bracket 13 reaches the first state, the filter element 14 and the wet curtain 12 can be positioned facing each other, and the orthographic projection of the filter element 14 on the vertical plane will not shift with the orthographic projection of the wet curtain 12 on the vertical plane. This ensures that the air passing through the wet curtain 12 is essentially clean airflow, minimizing contact between airborne dust, particles, and other pollutants and the wet curtain 12. Simultaneously, the annular groove 151 also serves a limiting function; when the first groove 1613 of the hook 161 is engaged with the annular groove 151 of the water pipe 15, it restricts the second bracket 13 from sliding horizontally.

[0068] In this embodiment, the installation process of the second bracket 13 is as follows: First, align the hook 161 of the second bracket 13 with the annular groove 151 of the water pipe 15, and forcefully snap the hook 161 of the second bracket 13 into the annular groove 151 of the water pipe 15. When a "click" sound is heard, it indicates that the installation is in place. Then, apply force to make the moving end 132 of the second bracket 13 rotate downward around the water pipe 15 until the filter element 14 of the second bracket 13 is set facing the wet curtain 12 of the first bracket 11.

[0069] In an embodiment not shown in the figure, a first magnetic part is provided on the first groove 1613, and a second magnetic part is provided on the outer periphery of the water pipe 15. The first magnetic part and the second magnetic part have a magnetic force that attracts each other. The first magnetic part and the second magnetic part can be set as arc-shaped magnetic sheets made of magnetic material. The mutual attraction between the first magnetic part and the second magnetic part can improve the installation stability of the second bracket 13. If the humidification component 1 is affected by external force during operation, causing the second bracket 13 to shift in the horizontal direction relative to the first bracket 11, the magnetic force between the first magnetic part and the second magnetic part will cause the mounting part 16 to tend to return to the initial installation position. This can prevent the second bracket 13 from shifting in the horizontal direction relative to the first bracket 11, so that the filter element 14 and the wet curtain 12 can be set facing each other, and the orthographic projection of the filter element 14 on the vertical plane will not be offset from the orthographic projection of the wet curtain 12 on the vertical plane, thereby ensuring that the air passing through the wet curtain 12 is basically clean airflow.

[0070] Furthermore, a first clearance portion 112 is provided on the side of the first bracket 11 near the mounting portion 16 to prevent interference between the hook 161 and the first bracket 11 during the rotation of the second bracket 13. Figure 4 As shown, the first clearance portion 112 can be configured as a through groove, that is, a through groove is provided on the side of the first bracket 11 near the mounting portion 16. The through groove corresponds to the hook 161. During the rotation of the second bracket 13, the end of the hook 161 near the first bracket 11 can rotate through the through groove, thereby avoiding interference between the hook 161 and the first bracket 11. If there are multiple hooks 161, then there are correspondingly multiple first clearance portions 112, with each first clearance portion 112 corresponding to a hook 161.

[0071] In an embodiment not shown in the figure, the mounting part 16 may include a first connecting plate and a hinge. The first connecting plate is disposed on the second bracket 13. The hinge has an intersecting first surface and a second surface. The first surface of the hinge can be connected to the first connecting plate by screws, and the second surface of the hinge can be connected to the first bracket 11 by screws. With this structure, a rotatable connection can be achieved between the mounting part 16 and the first bracket 11. The hinge may be a damping hinge, and the second surface of the damping hinge can be connected to the top of the first bracket 11. The hinge axis of the damping hinge is parallel to the horizontal direction. When the user pulls the second bracket 13, causing the moving end 132 of the second bracket 13 to flip upwards, the moving end 132 of the second bracket 13 moves away from the first bracket 11 to reach a second state. There is sufficient operating space between the first bracket 11 and the second bracket 13, facilitating the replacement of the wet curtain 12 or checking for blockages in the water system. When the user pulls the second bracket 13, causing the moving end 132 of the second bracket 13 to flip downwards, the moving end 132 of the second bracket 13 approaches the first bracket 11 and reaches the first state. At this time, air can pass through the filter element 14 and the wet curtain 12 in sequence, or air can pass through the wet curtain 12 and the filter element 14 in sequence, so as to simultaneously achieve the functions of filtration and humidification, and obtain high-humidity clean air. Of course, the second side of the hinge can also be connected to the side of the first bracket 11 by screws. The hinge axis of the damping hinge is parallel to the vertical direction, so that the moving end 132 of the second bracket 13 can rotate left and right around the vertical direction. Due to the first mounting plate, in the first state, the side of the second bracket 13 facing the wet curtain 12 is a certain distance away from the side of the wet curtain 12 facing the filter element 14, thereby avoiding interference between the filter element 14 and the wet curtain 12 during the rotation of the second bracket 13.

[0072] In an embodiment not shown in the figure, the mounting part 16 may include a second connecting plate and a pin. The second connecting plate is disposed on the first bracket 11, and a third connecting plate is disposed on the first bracket 11. The third connecting plate is provided with a rotating groove, and the pin is rotatably connected to the rotating groove, thereby realizing the rotatable connection between the mounting part 16 and the first bracket 11. The third connecting plate may be disposed on the top of the first bracket 11, and the axis of the pin is parallel to the horizontal direction. When the user pulls the second bracket 13, causing the moving end 132 of the second bracket 13 to flip upward, the moving end 132 of the second bracket 13 moves away from the first bracket 11 and reaches a second state. There is sufficient operating space between the first bracket 11 and the second bracket 13, which facilitates the replacement of the wet curtain 12 or the inspection of whether the water system is blocked. When the user pulls the second bracket 13, causing the moving end 132 of the second bracket 13 to flip downwards, the moving end 132 of the second bracket 13 approaches the first bracket 11 and reaches the first state. At this time, air can pass through the filter element 14 and the wet curtain 12 in sequence, or air can pass through the wet curtain 12 and the filter element 14 in sequence, so as to simultaneously achieve the functions of filtration and humidification, and obtain high-humidity clean air. Of course, the third connecting plate can also be set on the side of the first bracket 11, with the axis of the pin parallel to the vertical direction, so that the moving end 132 of the second bracket 13 can rotate left and right around the vertical direction. Due to the provision of the second mounting plate, in the first state, the side of the second bracket 13 facing the wet curtain 12 is at a certain distance from the side of the wet curtain 12 facing the filter element 14, thereby avoiding interference between the filter element 14 and the wet curtain 12 during the rotation of the second bracket 13.

[0073] In some embodiments, such as Figure 4 and Figure 5As shown, the first bracket 11 is provided with a first positioning ear 113, and the second bracket 13 is provided with a second positioning ear 136 that cooperates with the first positioning ear 113. The first positioning ear 113 may be provided with a second groove. When the moving end 132 of the second bracket 13 approaches the first bracket 11 and reaches the first state, the second positioning ear 136 can be embedded and connected to the second groove of the first positioning ear 113 to realize the positioning of the second bracket 13. Optionally, if the moving end 132 of the second bracket 13 can be flipped up and down relative to the first bracket 11, two first positioning ears 113 can be provided, respectively located on both sides of the horizontal direction, i.e., on the left and right sides of the first bracket 11. Two second positioning ears 136 are also provided, and the two second positioning ears 136 are connected one-to-one with the first positioning ears 113, thereby limiting the displacement of the second bracket 13 in the horizontal direction. That is, after the second bracket 13 reaches the first state, it will not move left or right relative to the first bracket 11, and the orthographic projection of the filter element 14 on the vertical plane will not deviate from the orthographic projection of the wet curtain 12 on the vertical plane, thereby ensuring that the air passing through the wet curtain 12 is basically clean airflow. The two first positioning ears 113 have different lengths in the horizontal direction. Through the above-mentioned foolproof design, users can easily identify the front and back of the second bracket 13. Optionally, if the moving end 132 of the second support 13 can rotate left and right relative to the first support 11, two first positioning ears 113 can be provided, with the two first positioning ears 113 respectively located on both sides of the vertical direction, that is, on the upper and lower sides of the first support 11. Two second positioning ears 136 are also provided, and the two second positioning ears 136 are connected one-to-one with the first positioning ears 113, thereby limiting the displacement of the second support 13 in the vertical direction. The orthographic projection of the filter element 14 on the vertical plane will not deviate from the orthographic projection of the wet curtain 12 on the vertical plane, thereby ensuring that the air passing through the wet curtain 12 is basically clean airflow. Of course, the number of first positioning ears 113 can also be three, four, etc., which will not be elaborated here.

[0074] In one exemplary embodiment, such as Figure 4 and Figure 7As shown, the first bracket 11 is provided with a first buckle 114, and the second bracket 13 is provided with a second buckle 137 connected to the first buckle 114. When the moving end 132 of the second bracket 13 approaches the first bracket 11 and reaches the first state, the first buckle 114 and the second buckle 137 engage and connect, thereby limiting the position of the second bracket 13. Optionally, if the moving end 132 of the second bracket 13 can be flipped up and down relative to the first bracket 11, two first buckles 114 can be provided, with the two first buckles 114 respectively provided on both sides of the horizontal direction, that is, on the left and right sides of the first bracket 11. Two second buckles 137 are also provided, and the two second buckles 137 are connected to the first buckles 114 one by one, thereby limiting the displacement of the second bracket 13 in the horizontal direction. That is, after the second bracket 13 reaches the first state, the second bracket 13 will not move left or right relative to the first bracket 11, nor will the second bracket 13 move back and forth relative to the first bracket 11. The orthographic projection of the filter element 14 on the vertical plane will not deviate from the orthographic projection of the wet curtain 12 on the vertical plane, thereby ensuring that the air passing through the wet curtain 12 is basically clean airflow. Optionally, if the moving end 132 of the second bracket 13 can rotate left and right relative to the first bracket 11, two first buckles 114 can be provided, with the two first buckles 114 respectively located on both sides of the vertical direction, that is, on the upper and lower sides of the first bracket 11. Two second buckles 137 are also provided, and the two second buckles 137 are connected to the first buckles 114 one-to-one, thereby limiting the displacement of the second bracket 13 in the vertical direction. The orthographic projection of the filter element 14 on the vertical plane will not deviate from the orthographic projection of the wet curtain 12 on the vertical plane, thereby ensuring that the air passing through the wet curtain 12 is basically clean airflow. Of course, the number of first buckles 114 can also be three, four, etc., which will not be elaborated here.

[0075] This embodiment can also be combined with the foregoing embodiments. For example, in a preferred embodiment, the first bracket 11 is provided with a first positioning ear 113, the second bracket 13 is provided with a second positioning ear 136 that cooperates with the first positioning ear 113, the first bracket 11 is provided with a first buckle 114, and the second bracket 13 is provided with a second buckle 137 that connects to the first buckle 114. In this way, the orthographic projection of the filter element 14 on the vertical plane can be avoided to the greatest extent possible from the orthographic projection of the wet curtain 12 on the vertical plane, thereby ensuring that the air passing through the wet curtain 12 is essentially a clean airflow.

[0076] In this embodiment, the installation process of the second bracket 13 is as follows: First, align the hook 161 of the second bracket 13 with the annular groove 151 of the water pipe 15, and forcefully engage the hook 161 of the second bracket 13 into the annular groove 151 of the water pipe 15. A "click" sound indicates that the installation is in place. Next, apply force to make the moving end 132 of the second bracket 13 rotate downwards around the water pipe 15 until the second positioning ear 136 of the second bracket 13 is embedded in the second groove of the first positioning ear 113, and the second buckle 137 of the second bracket 13 is engaged with the first buckle 114 of the first bracket 11. If it is necessary to disassemble the second bracket 13, apply force to make the moving end 132 of the second bracket 13 rotate upwards around the water pipe 15. The second buckle 137 separates from the first buckle 114, and the second positioning ear 136 separates from the first positioning ear 113; then, the hook 161 of the second bracket 13 is removed from the annular groove 151 of the water pipe 15, so that the filter element 14 can be easily replaced.

[0077] In one embodiment, the humidification component 1 includes a water pump. The outlet of the water pump is connected to a water pipe 15 via a pipeline, and the inlet of the water pump is connected to a water storage tank or an external water system. When the inlet of the water pump is connected to the water storage tank, the water stored in the tank can enter the water pipe 15 through the pipeline, and then enter the wet curtain 12 through the outlet of the water pipe 15. Under the action of gravity, the water permeates downwards along the surface of the wet curtain 12, forming a uniform water film. When clean air passes through the wet curtain 12, the moisture evaporates rapidly, making the airflow high-humidity clean air, thereby increasing the air humidity. When the inlet of the water pump is connected to an external water system, an external water source can enter the water pipe 15 through the pipeline, and then enter the wet curtain 12 through the outlet of the water pipe 15. Under the action of gravity, the water permeates downwards along the surface of the wet curtain 12, forming a uniform water film. When clean air passes through the wet curtain 12, the moisture evaporates rapidly, making the airflow high-humidity clean air, thereby increasing the air humidity.

[0078] In one embodiment, such as Figure 5 As shown, the filter element 14 includes multiple layers of filter screens 141 with different mesh counts, capable of capturing particles of different sizes. The mesh counts of the multiple filter screens 141 are arranged sequentially from low to high based on the airflow direction. When outside air passes through the multiple filter screens 141, dust, particles, and other pollutants in the air are captured. The mesh counts of the multiple filter screens 141 are arranged sequentially from low to high based on the airflow direction. That is, if the air passes through the filter element 14 first and then through the wet curtain 12, the mesh count of the filter screens 141 closer to the front of the second support 13 will be lower than that of the filter screens 141 farther from the wet curtain 12. If the air passes through the wet curtain 12 first and then through the filter element 14, the mesh count of the filter screens 141 closer to the front of the second support 13 will be higher than that of the filter screens 141 farther from the wet curtain 12. Users can easily install and remove the filter screens 141 for cleaning or replacement as needed.

[0079] like Figure 8 As shown, this application embodiment provides an electrical device 100, including a body and a humidification component 1 as described above. The electrical device 100 is at least one of the following: a cool fan, a humidifier, and an air purifier.

[0080] It should be noted that the main body is specifically the main structure of the electrical device 100, with the first bracket 11 mounted on it. For example, when the electrical device 100 is a fan purifier, the main body is the fan body 2. The fan body 2 uses a high-performance material to make the impeller, ensuring its durability and air driving force. The impeller is installed at the core of the fan purifier and is driven to rotate by a motor, generating a strong airflow. The second bracket 13 is in the first state, closed relative to the first bracket 11. At this time, the filter element 14 and the wet curtain 12 are positioned facing each other. Air can then pass through the filter element 14, which captures dust, particles, and other pollutants in the air, turning the airflow into clean air. This clean air then passes through the wet curtain 12, where moisture evaporates rapidly, increasing the humidity of the clean air and resulting in high-humidity clean air. Alternatively, the air can first pass through the wet curtain 12, where moisture evaporates rapidly, turning the airflow into high-humidity air. This high-humidity air then passes through the filter element 14, resulting in high-humidity clean air and improving indoor air quality. During the above-mentioned operation, the electrical device 100 simultaneously purifies and humidifies the air, reducing the space occupied by multiple devices and lowering the cost and complexity of use.

[0081] In one embodiment, such as Figure 8 As shown, when the electrical device 100 is an air cooler, the air cooler includes a fan body 2, which includes an air inlet side 21 and an air outlet side 22 arranged opposite to each other. A humidifying component 1 is provided on the air inlet side 21 and / or the air outlet side 22 of the fan body 2. For example, the humidifying component 1 can be located on the air inlet side 21 of the fan body 2. When the fan body 2 is working, external air can pass through the filter element 14 and the evaporative cooling pad 12 in sequence to obtain high-humidity clean air. Of course, external air can also pass through the evaporative cooling pad 12 first and then through the filter element 14 to obtain high-humidity clean air, thus improving indoor air quality. Alternatively, the humidifying component 1 can be located on the air outlet side 22 of the fan body 2; or, both the air inlet side 21 and the air outlet side 22 of the fan body 2 are provided with humidifying components 1, so that the air is humidified and purified twice, which can further improve indoor air quality and reduce the probability of mold growth on the evaporative cooling pad 12.

[0082] In one embodiment, such as Figure 9As shown, a cover 3 is provided on the air outlet side 22 of the fan body 2, and an installation cavity 31 is provided between the fan body 2 and the cover 3. The humidifying component 1 is disposed in the installation cavity 31. By placing the humidifying component 1 in the installation cavity 31, the arrangement space between the cover 3 and the fan body 2 is effectively utilized, which can further save the space occupied by the electrical device 100.
