Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a fan. Background Art

[0002] The design of traditional fans often focuses on basic air circulation functions. Although the fan blade structure can effectively promote indoor air circulation, it is also easy to become a gathering place for particulate matter such as dust and hair. Over time, these accumulated dirt not only reduces the operating efficiency of the fan, but may also blow the accumulated dust and other tiny substances towards the user during operation, thereby affecting the user's respiratory health.

[0003] Although there are fan products with air purification functions on the market, the purification effect of such fan products is relatively low, and the design may be too complicated, causing users to face difficulties in assembly and disassembly during cleaning and maintenance. Utility Model Content

[0004] The present application provides a fan to solve the technical problems that existing fan products have relatively low purification effects and may be too complicated in design, resulting in users facing difficulties in assembly and disassembly during cleaning and maintenance.

[0005] In a first aspect, the present application provides a fan, the fan comprising a fan body, an air inlet cover and a filter;

[0006] Among them, the fan body has an air inlet side and an air outlet side arranged opposite to each other, the air inlet cover is detachably installed on the air inlet side of the fan body, and the air inlet cover and the fan body together enclose a accommodating space; the filter is installed in the accommodating space, and the opposite sides of the filter are respectively arranged opposite to the fan body and the air inlet cover.

[0007] A further technical solution is that the fan body is provided with a first magnetic part, the air inlet cover is provided with a second magnetic part, and the second magnetic part cooperates with the first magnetic part by magnetic attraction, so that the air inlet cover can be detachably installed on the fan body.

[0008] A further technical solution is that the first magnetic component is a magnet and the second magnetic component is a screw.

[0009] A further technical solution is that the fan also includes a limiting structure, which is connected to the fan body or the air inlet cover and is used to limit the filter screen in the accommodating space.

[0010] A further technical solution is that the limiting structure includes a limiting side wall, which is connected to the air inlet cover body, surrounds the outer circumference of the filter screen and fits against the outer circumferential wall of the filter screen to limit the radial movement of the filter screen along the fan body.

[0011] A further technical solution is that the limiting structure includes a limiting buckle, which is connected to the air inlet cover and is used to limit the axial movement of the filter screen along the fan body.

[0012] A further technical solution is that the limiting structure and the air inlet cover are integrally formed.

[0013] A further technical solution is that a first guide portion is provided on the outer periphery of the fan body, a second guide portion is convexly provided on the air inlet cover, the second guide portion cooperates with the first guide portion for guiding, and both the first guide portion and the second guide portion extend along the axial direction of the fan body.

[0014] A further technical solution is that the first guide portion includes a guide groove, the second guide portion includes a guide rib, the guide rib and the guide groove both extend along the axial direction of the fan body, and the guide rib is slidably located in the guide groove.

[0015] A further technical solution is that the filter is a HEPA filter.

[0016] The beneficial effect of the present application is as follows: Different from the prior art, the present application sets a filter in the fan. Since the filter can effectively intercept pollutants such as dust, hair, pollen, and tiny particles in the air, as the fan runs, when the air inhaled on the air inlet side passes through the filter, these dust, hair and other particulate matter will be blocked or adsorbed by the filter, thereby purifying the air and preventing the fan from blowing accumulated dust and other tiny substances toward the user during operation. At the same time, it also avoids the accumulation of pollutants inside the fan, which may cause the wind to weaken or the noise to increase, thereby maintaining efficient wind output and improving the user experience. The filter can also protect the internal mechanical structure of the fan, such as the motor, blades, etc., from being disturbed by impurities such as dust, thereby reducing the maintenance frequency of the fan and extending the service life of the fan.

[0017] In addition, the present application arranges an air inlet cover that can be detachably installed on the air inlet side of the fan body, and the filter is installed in the accommodating space formed by the air inlet cover and the fan body. In this way, when the filter reaches the end of its service life or is severely contaminated and needs to be replaced, the user can easily disassemble the air inlet cover and directly remove the filter for cleaning or replacement without complicated disassembly of the fan body, thereby improving the convenience of product use.

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0024] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention may repeat reference numbers 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.

[0025] The design of traditional fans often focuses on basic air circulation functions. Although the fan blade structure can effectively promote indoor air circulation, it is also easy to become a gathering place for particulate matter such as dust and hair. Over time, these accumulated dirt not only reduces the operating efficiency of the fan, but may also blow the accumulated dust and other tiny substances towards the user during operation, thereby affecting the user's respiratory health.

[0026] Although there are fan products with air purification functions on the market, the purification effect of such fan products is relatively low, and the design may be too complicated, causing users to face difficulties in assembly and disassembly during cleaning and maintenance.

[0027] Therefore, in order to solve the technical problem that the existing switch device can only be used to control the on and off of the current but does not provide additional functions or feedback, the present application provides a fan that can detect and visualize the status of the lamp tube. Please refer to the following embodiments for details.

[0028] Example 1

[0029] See also Figure 1-Figure 4 , Figure 1 This is a schematic diagram of the assembly of a fan according to an embodiment of the present application; Figure 2 An exploded schematic diagram of an embodiment of a fan provided by the present application; Figure 3 A schematic diagram of the structure of the fan body provided in this application; Figure 4 This is a schematic structural diagram of an embodiment of the air inlet cover provided in the present application.

[0030] like Figure 1-Figure 2 As shown, the fan 10 includes a fan body 100 , an air inlet cover 200 and a filter 300 .

[0031] Among them, the fan body 100 has an air inlet side and an air outlet side arranged opposite to each other, the air inlet cover 200 can be detachably installed on the air inlet side of the fan body 100, and the air inlet cover 200 and the fan body 100 together enclose a accommodating space 400; the filter 300 is installed in the accommodating space 400, and the opposite sides of the filter 300 are respectively arranged opposite to the fan body 100 and the air inlet cover 200.

[0032] The fan body 100 can be preferably made of lightweight and durable plastic or metal materials to ensure a stable structure and easy to move. The fan body 100 has an air inlet side and an air outlet side that are arranged opposite to each other. The air inlet side is designed with an interface for installing the air inlet cover 200, and the air outlet side is provided with an air outlet, which can be designed to be multi-directionally adjustable to meet the air supply requirements at different angles.

[0033] The air inlet cover 200 is a detachable component, for example, it is firmly connected to the air inlet side of the fan body 100 by means of buckles, screws or magnets, so that the user can easily disassemble and assemble it without tools. Among them, the surface of the air inlet cover 200 can be designed with fine ventilation holes to ensure air circulation and prevent large foreign objects from entering. The internal structure of the air inlet cover 200 is closely matched with the fan body 100 to form a closed accommodating space 400.

[0034] The receiving space 400 formed by the air inlet cover 200 and the fan body 100 is used to install the filter 300. The filter 300 can be installed stably without being loose or too tight by accurately measuring the specifications of the filter 300 and designing a matching receiving space 400, so as to ensure that the filter 300 is installed stably, and is neither loose nor too tight, so that the user can easily replace it, while ensuring the purification effect and the compactness of the overall structure.

[0035] The filter 300 can be designed as a replaceable structure, and usually uses a high-efficiency HEPA filter or other suitable air purification materials, which can effectively filter dust, pollen, smoke and other tiny particles in the air. The filter 300 is closely attached to the inner wall of the accommodating space 400 to ensure that all air entering the fan 10 must pass through the filter 300, thereby achieving a purification effect.

[0036] In addition, in order to ensure effective filtering performance, the filter 300 usually needs to have a certain thickness and volume, such as a multi-layer HEPA filter or an activated carbon filter layer, which can increase the filtering efficiency, but also takes up a large space. Therefore, the present application forms a receiving space 400 by enclosing the air inlet cover 200 and the fan body 100 together, so that the filter 300 can be installed in the receiving space 400, which can ensure that the filter 300 can form a good seal with the fan body 100 and the air inlet cover 200 after installation, and prevent unpurified air from bypassing the filter 300 and directly entering the fan 10. At the same time, the design of the receiving space 400 also needs to take into account the smoothness of air flow, ensuring that the air will not generate too much resistance when passing through the filter 300, affecting the wind output and energy efficiency of the fan 10.

[0037] Working principle: When the fan 10 is turned on, air is sucked in from the air inlet side, purified by the filter 300, and then pushed by the internal fan of the fan body 100 and sent out through the air outlet to form a circulating airflow. During the whole process, the filter 300 continuously purifies the air.

[0038] In this embodiment, a filter 300 is provided in the fan 10. Since the filter 300 can effectively intercept pollutants such as dust, hair, pollen, and tiny particles in the air, as the fan 10 runs, when the air sucked in from the air inlet side passes through the filter 300, these dust, hair and other particulate matter will be blocked or adsorbed by the filter 300, thereby purifying the air and preventing the fan 10 from blowing the accumulated dust and other tiny substances toward the user during operation. At the same time, it also prevents the accumulation of pollutants inside the fan 10, which may cause the wind force to weaken or the noise to increase, thereby maintaining the high efficiency of the wind force and improving the user experience. In addition, the filter 300 can also protect the internal mechanical structure of the fan 10, such as the motor and blades, from being disturbed by impurities such as dust, thereby reducing the maintenance frequency of the fan 10 and extending the service life of the fan 10.

[0039] In addition, the present application arranges an air inlet cover 200 which can be detachably installed on the air inlet side of the fan body 100, and the filter 300 is installed in the accommodating space 400 formed by the air inlet cover 200 and the fan body 100. In this way, when the filter 300 reaches the end of its service life or is seriously contaminated and needs to be replaced, the user can easily disassemble the air inlet cover 200 by himself, and directly remove the filter 300 for cleaning or replacement without complicated disassembly of the fan 10 body, thereby improving the convenience of product use and further improving the user experience.

[0040] In some embodiments, the fan body 100 is provided with a first magnetic component 110 , and the air inlet cover 200 is provided with a second magnetic component 210 . The second magnetic component 210 is magnetically coupled with the first magnetic component 110 so that the air inlet cover 200 can be detachably installed on the fan body 100 .

[0041] Among them, a first magnetic component 110 can be set inside or at the edge of the fan body 100 near the air inlet side. These magnetic components can be permanent magnets or other types of strong magnetic materials. They are fixed in predetermined positions to ensure that they can provide sufficient suction without affecting the overall appearance and structural strength of the fan 10.

[0042] Exemplarily, the first magnetic member 110 and the second magnetic member 210 may both be magnets; or the first magnetic member 110 is a screw and the second magnetic member 210 is a magnet; or the first magnetic member 110 is a magnet and the second magnetic member 210 is a screw.

[0043] In the first embodiment provided in the present application, it is preferred that the first magnetic member 110 is a magnet and the second magnetic member 210 is a screw.

[0044] By configuring the second magnetic member 210 of the air inlet cover 200 as a screw, the connection stability between the second magnetic member 210 and the air inlet cover 200 can be improved.

[0045] When the user needs to clean the inside of the fan 10 or replace the filter 300, the user only needs to gently rotate or apply a slight pulling force to easily separate the air inlet cover 200 using the magnetic attraction and the mechanical structure of the screws. No additional tools are required, which greatly simplifies the maintenance steps and improves the user experience.

[0046] In addition, there may be a plurality of first magnetic members 110 , a plurality of second magnetic members 210 , and the plurality of second magnetic members 210 respectively correspond to the plurality of first magnetic members 110 .

[0047] For example, Figure 1-Figure 4 As shown, in the embodiment 1 provided in the present application, the fan body 100 has three fixed positions for placing magnets, and the air inlet cover 200, i.e. the rear net, is provided with three screw columns for placing screws.

[0048] In some embodiments, the fan 10 further includes a limiting structure 500 , which is connected to the fan body 100 or the air inlet cover 200 and is used to limit the filter 300 in the accommodating space 400 .

[0049] The limiting structure 500 may be in the form of an elastic buckle, a slide rail and a positioning groove, or a spring-loaded locking device. For example, the edge of the fan body 100 is designed with a circle of positioning grooves that match the size of the filter 300, and the air inlet cover 200 is correspondingly provided with a protruding structure or an elastic buckle that can be inserted into the positioning groove. When the air inlet cover 200 is installed in place, these protruding structures or elastic buckles automatically and tightly combine with the positioning groove, thereby fixing the filter 300 in the accommodating space 400, avoiding displacement caused by vibration or external force during use.

[0050] Alternatively, the edge of the air inlet cover 200 is designed with a circle of positioning grooves that match the size of the filter 300, and the fan body 100 is correspondingly configured with a protruding structure or elastic buckle that can be inserted into the positioning groove. When the fan body 100 is installed in place, these protruding structures or elastic buckles automatically and tightly combine with the positioning grooves, thereby fixing the filter 300 in the accommodating space 400, avoiding displacement caused by vibration or external force during use.

[0051] The limiting structure 500 and the air inlet cover 200 are integrally formed.

[0052] The limiting structure 500 is integrally formed with the air inlet cover body 200 to form a whole. Compared with the structure connected by assembly, the integral molding reduces the number of connection parts and has higher structural strength and stability, thereby reducing the risk of loosening or falling off due to vibration, long-term use or external force impact, and ensuring that the filter 300 can be firmly fixed in place throughout its service life.

[0053] The limiting structure 500 includes a limiting side wall 510 , which is connected to the air inlet cover 200 . The limiting side wall 510 surrounds the periphery of the filter 300 and fits against the outer peripheral wall of the filter 300 to limit the radial movement of the filter 300 along the fan body 100 .

[0054] The limiting side wall 510 is distributed around the periphery of the filter 300 and is integrally formed with the air inlet cover 200 to form an annular structure. The annular limiting side wall 510 is designed with an appropriate inner diameter size to fit the outer peripheral wall of the filter 300, ensuring that after the filter 300 is installed, its edge can be close to the limiting side wall 510, neither causing installation difficulties due to being too tight, nor being too loose to lose the fixing effect.

[0055] like Figure 4 As shown, the inner side wall of the air inlet cover 200, namely the limiting side wall 510, serves as the first limiting surface of the filter 300, and the first limiting surface fits with the entire side surface of the filter 300 without any gap.

[0056] The limiting side wall 510 is made of the same or compatible material as the air inlet cover 200, ensuring the stability and durability of the overall structure. Through injection molding or mold forming, the limiting side wall 510 is seamlessly connected to the air inlet cover 200, and the edge is smooth and burr-free to avoid scratches that may be caused when installing or removing the filter 300.

[0057] By providing a limiting side wall 510 that is close to the outer periphery of the filter 300, not only can the filter 300 be effectively fixed to prevent it from moving or deflecting during the operation of the fan 10, thereby reducing the noise and energy consumption generated during the operation of the fan 10, but also the obstruction of the surface of the filter 300 can be avoided. In this way, air can pass through every part of the filter 300 and fully utilize the entire area of ​​the filter 300 for purification, thereby ensuring the maximization of the filtering efficiency.

[0058] In some embodiments, the limiting structure 500 includes a limiting buckle 520 , which is connected to the air inlet cover 200 and is used to limit the axial movement of the filter 300 along the fan body 100 .

[0059] There may be a plurality of limit buckles 520 , which are placed at intervals along the circumference of the inner circle of the air inlet cover body 200 .

[0060] When the filter 300 is installed on the air inlet cover 200, the limit buckle 520 will automatically align with the corresponding position of the filter 300. By simply pressing, the buckle can firmly lock the filter 300 to prevent it from sliding or falling out along the axial direction.

[0061] There may be a plurality of limit buckles 520 , which are placed at intervals along the circumference of the inner circle of the air inlet cover body 200 .

[0062] In some embodiments, a first guide portion 120 is provided on the outer periphery of the fan body 100, and a second guide portion 220 is protruding from the air inlet cover 200. The second guide portion 220 is guided and matched with the first guide portion 120, and both the first guide portion 120 and the second guide portion 220 extend along the axial direction of the fan body 100.

[0063] like Figure 3 and Figure 4 As shown, the first guide portion 120 and the second guide portion 220 can be set to be U-shaped. For example, a U-shaped groove can be set on the periphery of the fan body 100, and its structural form matches the first guide portion 120, and the second guide portion 220 protruding from the air inlet cover 200, such as a flange, can be embedded in the U-shaped groove set on the periphery of the fan body 100.

[0064] The guiding cooperation between the first guide portion 120 and the second guide portion 220 ensures that the air inlet cover 200 can be accurately aligned with the fan body 100 each time it is installed, thereby avoiding misalignment or tilting and improving the accuracy and reliability of the overall assembly.

[0065] In some embodiments, the first guide portion 120 may further include a guide groove 121 , and the second guide portion 220 may further include a guide rib 221 . Both the guide rib 221 and the guide groove 121 extend along the axial direction of the fan body 100 , and the guide rib 221 may be slidably located in the guide groove 121 .

[0066] Specifically, the first guide portion 120 can be designed with one or more guide grooves 121, which are evenly arranged along the axial direction of the fan body 100, and their shapes and sizes match the guide ribs 221, and these guide grooves 121 have a certain width and depth, which are sufficient to accommodate the guide ribs 221 on the air inlet cover 200.

[0067] Similarly, the second guide portion 220 of the air inlet cover 200 can be designed with multiple guide ribs 221 protruding at the corresponding position. The height of the guide ribs 221 is consistent and matches the cross-sectional shape of the guide groove 121. It can be rectangular or other shapes to ensure good guidance and stability during sliding, while avoiding assembly difficulties caused by excessive freedom.

[0068] Among them, the end face of the guide rib 221 with the same height is the limiting surface, and one plane of the filter screen 300 is laid flat and matched with the limiting surface of the air inlet cover body 200, i.e., the rear net, and the limiting buckle 520 hooks the other side of the filter screen 300 to fix the filter screen 300 in the limiting structure of the air inlet cover body 200.

[0069] When installing the air inlet cover 200, the user only needs to align the guide rib 221 with the guide groove 121 and gently push it axially, and the guide rib 221 can be inserted into the guide groove 121. When the magnet on the fan body 100 attracts the screws on the air inlet cover 200, it can be installed in place.

[0070] By using the guide ribs 221 in conjunction with the corresponding guide grooves 121 , the installation stability of the air inlet cover 200 and the fan body 100 can be enhanced, deviation during installation can be avoided, and the assembly accuracy can be improved.

[0071] The device embodiments described above are merely illustrative, wherein the units described as separate components may or may not be physically separated, and the components shown as units may or may not be physical units, i.e., they may be located in one place, or may be distributed over multiple network units.
