Abstract

This utility model relates to the field of air purifier technology and discloses an air purifier structure that allows observation of internal hair adsorption. The structure includes a main frame composed of a front shell, a rear shell, and a middle frame. A transparent observation window is integrated on the front of the front shell, and a pull-out dust collection plate and a separating filter plate form a dual filtration system. The filter and fan blades are coaxially connected and mounted on a motor bracket to ensure operational stability.

The visual structure enables real-time monitoring of hair accumulation.

Description

Technical Field

[0001] This utility model relates to the field of air purifier technology, specifically to an air purifier structure that allows observation of the internal hair adsorption situation. Background Technology

[0002] An air purifier is a household appliance that purifies indoor air and improves air quality through technologies such as filtration, adsorption, and decomposition. The core functions of an air purifier are: removing particulate matter: effectively filtering PM2.5, pollen, dust, pet hair, and other tiny particles (mainly HEPA filters); adsorbing harmful gases: activated carbon filters adsorb formaldehyde, TVOC (from renovations), and odors (such as smoke and pet odors); sterilizing and disinfecting: some models are equipped with ultraviolet (UV-C) or plasma technology to kill bacteria and viruses; alleviating allergies: reducing allergens (such as dust mites and mold spores), making it suitable for people with allergies. The working principle of an air purifier is: it draws in air through a fan, filters it through multiple layers of filters, and then discharges clean air.

[0003] Traditional air purifiers often lack a clear design, making it difficult for users to directly observe the internal filter's operation. This leads to problems like hair buildup causing duct blockage and reduced purification efficiency, which are often only discovered after the device's performance has noticeably declined. This design flaw not only increases maintenance costs for regular cleaning but also can shorten the overall lifespan of the device due to structural wear. This is especially problematic for pet-owning households or environments with a lot of hair, where the conflict between maintenance frequency and purification efficiency is even more pronounced. Current air purifiers primarily rely on complete filter replacement for cleaning, which increases operating costs and makes it difficult to thoroughly remove hair fibers adhering to the filter surface, thus affecting continuous filtration. Therefore, this paper proposes an air purifier structure that allows users to observe the internal hair adsorption status. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an air purifier structure that allows observation of internal hair adsorption, thereby solving the aforementioned technical problems of difficulty in directly observing the working status of the internal filter and the reliance on complete filter replacement for cleaning.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an air purifier structure that allows observation of internal hair adsorption, comprising:

[0008] The front shell and a transparent cover located in the center of the front of the front shell are provided. A rear shell is installed on the back of the front shell. A middle frame is added between the front shell and the rear shell. A top cover is installed on the upper surface of the middle frame. An operation panel, a control board, an LED board and a light-transmitting cover are respectively installed on the upper and lower surfaces of the top cover. A first air inlet and a second air inlet are respectively installed on the lower sides of the front shell and the rear shell. A handle is installed on the upper sides of both the front shell and the rear shell. A sensor cover is installed on the surface of the rear shell.

[0009] A filter screen is located at the front end of the inner cavity between the front and rear shells, and a fan blade is added to the back of the filter screen. A motor bracket is installed in the inner cavity between the front and rear shells, and a motor is installed on the surface of the motor bracket. The motor and the fan blade are coaxially connected.

[0010] A dust collection plate is positioned below the filter and is slidably connected to the front and rear shells. A separation filter plate is connected to the center of the dust collection plate's inner cavity. A fan is connected to the air outlet on the back of the dust collection plate, and a scraper is slidably connected to the front of the filter, slidingly adhering to the filter. Handles are installed on both sides of the scraper, extending outwards through the inner walls of the front and rear shells. Air enters the purifier's inner cavity simultaneously through the first and second air inlets located at the lower sides of the front and rear shells. The incoming airflow first contacts the filter, which physically blocks large particulate pollutants such as hair and fibers, achieving primary purification. The airflow after primary filtration is driven by the motor and forms a directional airflow through the fan blades, exiting from the air outlet of the rear shell. Users can directly observe the hair accumulation on the filter surface through the transparent cover in the center of the front of the front shell. When the amount of hair adsorbed on the filter surface reaches a preset threshold, the user can manually push the scraper along the filter surface by holding the handle. The close fit design between the scraper and the filter ensures that the accumulated hair is removed. Hair is scraped into the inner cavity of the dust collection plate. The fan starts, adsorbing the hair onto the separation filter plate. The fan then exhausts air outward. The fan has an independent switch and power supply. When the scraper moves along the filter screen, the fan is stopped. When the scraper finishes scraping, the fan starts, which avoids affecting the scraping operation of the filter screen. Pull the dust collection plate outward to separate it from the sliding track between the front and rear shells. The separation filter plate can be disassembled for cleaning or replacement. An outer cover can be added to the surface of the handle, allowing it to slide and fit against the surfaces of the front and rear shells, preventing outside air from directly entering the air purifier through the handle's movement groove.

[0011] Preferably, positioning grooves are provided on both sides of the inner wall of the dust collection plate, and positioning protrusions are installed on both sides of the filter screen. The positioning protrusions on both sides of the filter screen are inserted into the corresponding positioning grooves on the inner wall of the dust collection plate, and the precise docking of the filter screen and the dust collection plate is achieved through geometric positioning.

[0012] Preferably, the positioning protrusion and the positioning groove are positioned and shaped correspondingly, and the positioning protrusion and the positioning groove are inserted and connected. The cross-sectional shape of the positioning protrusion and the groove shape of the positioning groove are perfectly matched to form a gapless insertion fit.

[0013] Preferably, a guide pipe is installed at the center of the bottom of the inner cavity of the dust collection plate, and the air outlet of the guide pipe is connected to the air inlet of the fan. The guide pipe at the bottom of the inner cavity of the dust collection plate vertically guides the airflow intercepted by the filter plate to the air inlet of the fan, forming a straight airflow channel.

[0014] Preferably, both sides of the vertical guide pipe are connected to horizontal guide pipes, and air inlets are evenly distributed on the upper surfaces of both the vertical and horizontal guide pipes. The horizontal guide pipes on both sides of the vertical guide pipe collect airflow through the evenly distributed air inlets, forming a lateral diffusion air intake pattern.

[0015] Preferably, guide rods are connected to both sides of the back of the dust collection plate, and a connecting plate and a return spring are respectively sleeved on the surface of the guide rod. The connecting plate is connected to the scraper and the handle, and the two ends of the return spring are connected to the surfaces of the guide rod and the connecting plate, respectively. The scraper is slidably connected to the guide rod through the connecting plate. The return spring is compressed when the handle pushes the scraper, and after the external force is released, the spring force drives the scraper to automatically return to its original position.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides an air purifier structure that allows observation of the internal hair adsorption situation, and has the following beneficial effects:

[0018] 1. The air purifier structure allows users to observe the internal hair adsorption status. The integrated design of the transparent cover and front shell allows users to directly observe the hair adsorption status of the filter and dust collection plate area. Users can monitor the internal dirt accumulation in real time without disassembling the device. This visualization function not only makes it easier for users to clean and maintain in a timely manner and avoid airflow blockage or reduced purification efficiency caused by hair accumulation, but also extends the overall service life of the device by reducing unnecessary disassembly operations.

[0019] 2. The air purifier features an internal structure that allows observation of hair adsorption. The axial connection between the filter and the fan blades ensures the coaxiality of the core air purification components. Combined with the rigid fixation of the motor bracket, this effectively reduces vibration and noise during operation. The sliding scraper added to the back of the filter is externally controlled via a handle. Users can manually push and pull to remove hair fibers adhering to the filter surface, avoiding the cost of frequent filter replacements required by traditional purifiers, while maintaining high-efficiency filtration performance over long-term use.

[0020] 3. The air purifier structure allows observation of internal hair adsorption. The combination design of the dust collection plate and the separation filter plate creates a dual hair interception mechanism. The dust collection plate achieves rapid dumping of large particles of dirt through a sliding pull structure, while the separation filter plate provides secondary blocking for fine hair, preventing the collected dirt from being rolled up again by the airflow. The directional airflow channel formed by the matching fan not only ensures the smooth discharge of purified air, but also enhances the adsorption stability of hair and other impurities through the negative pressure effect.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides a technical solution: an air purifier structure that allows observation of internal hair adsorption, comprising: (See details) Figure 1 and Figure 2 The front shell 2 and the transparent cover 1 set in the center of the front of the front shell 2 are provided. The back shell 16 is installed on the back of the front shell 2. A middle frame 4 is added between the front shell 2 and the rear shell 16. A top cover 11 is installed on the upper surface of the middle frame 4. An operation panel 12, a control board 10, an LED board 9 and a light-transmitting cover 8 are respectively added to the upper and lower surfaces of the top cover 11. A first air inlet 7 and a second air inlet 15 are respectively installed on the lower sides of the front shell 2 and the rear shell 16. A handle block 13 is installed on the upper sides of both the front shell 2 and the rear shell 16. A sensor cover plate 17 is installed on the surface of the rear shell 16.

[0031] The filter screen 3 is located at the front end of the inner cavity between the front shell 2 and the rear shell 16, and a fan blade 14 is added to the back of the filter screen 3. A motor bracket 6 is installed in the inner cavity between the front shell 2 and the rear shell 16, and a motor 5 is installed on the surface of the motor bracket 6. The motor 5 and the fan blade 14 are coaxially connected.

[0032] A dust collection plate 30 is disposed below the filter screen 3 and is slidably connected to the front shell 2 and the rear shell 16. A separation filter plate 19 is connected to the center of the inner cavity of the dust collection plate 30, and a fan 18 is connected to the air outlet end on the back of the dust collection plate 30. A scraper 27 is slidably connected to the front of the filter screen 3 and is slidably attached to the filter screen 3. A handle 28 is installed on both sides of the scraper 27 and extends outward through the inner wall of the front shell 2 and the rear shell 16. Air enters the purifier cavity simultaneously through the first air inlet screen 7 and the second air inlet screen 15 located on the lower sides of the front shell 2 and the rear shell 16. The incoming airflow first contacts the filter screen 3, which physically blocks large particulate pollutants such as hair and fibers, achieving primary purification. The airflow after primary filtration is driven by the motor 5 and forms a directional airflow through the fan blade 14, and is discharged from the air outlet of the rear shell 16. The user can directly observe the hair accumulation on the surface of the filter screen 3 through the transparent cover 1 in the center of the front of the front shell 2. When the adsorption amount on the surface of the filter screen 3 reaches the preset threshold, the user can manually push the scraper 27 along the surface of the filter screen 3 by holding the handle 28. The close fit design of the scraper 27 and the filter screen 3 ensures that the accumulated hair is scraped off into the inner cavity of the dust collection plate 30. The fan 18 is started, adsorbing the hair and other pollutants onto the separation filter plate 19. The fan 18 then... Air is exhausted outwards, and the fan 18 has an independent switch and independent power supply. When the scraper 27 moves along the filter screen 3, the fan 18 is in a stopped state. When the scraper 27 finishes scraping, the fan 18 is in a started state, which can avoid affecting the scraping operation of the filter screen 3. Pull the dust collection plate 30 outwards to make it separate from the sliding track of the front shell 2 and the rear shell 16. The filter plate 19 can be disassembled for cleaning or replacement. At the same time, an outer cover can be added to the surface of the handle 28 so that the outer cover slides and fits against the surface of the front shell 2 and the rear shell 16. This can prevent outside air from directly entering the air purifier through the moving groove of the handle 28. The working status of the filter screen 3 can be observed in real time through the transparent cover 1, avoiding the problem of traditional purifiers requiring the shell to be disassembled to judge the degree of pollution of the filter screen 3. The combination design of the scraper 27 and the handle 28 shortens the cleaning time of the filter screen 3 surface.

[0033] Please see Figure 3 and Figure 4The dust collection plate 30 has positioning grooves 21 on both sides of its inner wall, and positioning protrusions 20 are installed on both sides of the filter screen 3. The positioning protrusions 20 on both sides of the filter screen 3 are inserted into the corresponding positioning grooves 21 on the inner wall of the dust collection plate 30. Through geometric positioning, the filter screen 3 and the dust collection plate 30 are precisely connected. This structure can prevent the filter screen 3 from shifting laterally under the impact of airflow, ensure that the distance between the filter screen 3 and the separating filter plate 19 is constant, avoid hair leakage caused by assembly errors, and simplify the disassembly and assembly process of the filter screen 3. The positioning protrusions 20 and the positioning grooves 21 are corresponding in position and shape, and the positioning protrusions 20 and the positioning grooves 21 are inserted and connected. The cross-sectional shape of the positioning protrusions 20 and the groove shape of the positioning grooves 21 are perfectly matched to form a gapless insertion fit. This design eliminates the movement gap at the connection between the filter screen 3 and the dust collection plate 30, prevents unfiltered airflow from bypassing the filter screen 3 and directly entering the dust collection plate 30, and ensures the reliability of the dual-stage filtration system. A guide vertical pipe 22 is installed at the center of the bottom of the inner cavity of the dust collection plate 30, and the air outlet of the guide vertical pipe 22 is connected to the air inlet of the fan 18. The guide vertical pipe 22 at the bottom of the inner cavity of the dust collection plate 30 vertically guides the airflow intercepted by the separation filter plate 19 to the air inlet of the fan 18, forming a straight airflow channel. The vertical guide design reduces the energy loss caused by airflow turning, improves the air intake efficiency of the fan 18, and reduces the vibration noise generated by airflow impact. Both sides of the air inlet of the guide vertical pipe 22 are connected to guide horizontal pipes 23, and air inlet holes 24 are evenly opened on the upper surface of the guide vertical pipe 22 and the guide horizontal pipe 23. The guide horizontal pipes 23 on both sides of the guide vertical pipe 22 collect airflow through the evenly distributed air inlet holes 24, forming a horizontal diffusion air intake mode. This structure expands the effective air intake area of ​​the dust collection plate 30, avoids the phenomenon of excessive local wind speed caused by single-point air intake, and improves the uniformity of hair adsorption of the separation filter plate 19.

[0034] Please see Figure 5 , Figure 6 and Figure 7 Guide rods 25 are connected to both sides of the back of the dust collection plate 30. A connecting plate 26 and a return spring 29 are respectively fitted onto the surface of the guide rods 25. The connecting plate 26 is connected to the scraper 27 and the handle 28, respectively. The two ends of the return spring 29 are connected to the surfaces of the guide rods 25 and the connecting plate 26, respectively. The scraper 27 is slidably connected to the guide rods 25 via the connecting plate 26. The return spring 29 is compressed when the handle 28 pushes the scraper 27. After the external force is released, the spring force drives the scraper 27 to automatically return to its original position. This mechanism enables the scraper 27 to complete a bidirectional cleaning action with a single manual operation: scraping hair on the outward trip and resetting for standby on the return trip. This reduces repetitive operation steps for the user and avoids indentations on the filter screen 3 caused by the scraper 27 remaining stationary for extended periods.

[0035] In this scheme, air enters the purifier cavity simultaneously through the first air inlet screen 7 and the second air inlet screen 15 set on the lower part of both sides of the front shell 2 and the rear shell 16. The incoming airflow first contacts the filter screen 3, and the filter screen 3 intercepts large particulate pollutants such as hair and fibers through physical barrier, thus completing the primary purification.

[0036] The airflow that has passed through the primary filter is driven by the motor 5 and forms a directional airflow through the fan blade 14. The airflow flows along a preset path and is discharged from the air outlet of the rear shell 16.

[0037] Users can directly observe the hair accumulation on the surface of the filter screen 3 through the transparent cover 1 in the center of the front of the front shell 2, and judge the degree of pollution of the filter screen 3 without disassembling the shell;

[0038] When the amount of hair adsorbed on the surface of the filter screen 3 reaches the preset threshold, the user holds the handle 28 and manually pushes the scraper 27 to slide along the surface of the filter screen 3. The scraper 27 and the filter screen 3 are designed to fit together to ensure that the accumulated hair is scraped into the inner cavity of the dust collection plate 30. At the same time, the return spring 29 is compressed.

[0039] After the scraping operation is completed, the blower 18 starts with an independent switch to adsorb contaminants such as hair onto the separation filter plate 19 and exhausts air outward through an independent power supply. When the scraper 27 moves, the blower 18 is in a stopped state to avoid interfering with the scraping operation. After the operation is completed, the blower 18 resumes operation.

[0040] Users can pull out the dust collection plate 30 to disengage it from the sliding track between the front shell 2 and the rear shell 16, clean the inner cavity of the dust collection plate 30, and remove the filter plate 19 for cleaning or replacement to ensure long-term filtration performance.

[0041] The positioning protrusions 20 on both sides of the filter screen 3 are inserted into the positioning grooves 21 on the inner wall of the dust collection plate 30. Through geometric positioning, the filter screen 3 and the dust collection plate 30 are precisely connected. This design prevents the filter screen 3 from shifting laterally under the impact of airflow, ensures that the distance between the filter screen 3 and the separation filter plate 19 is constant, and avoids hair leakage.

[0042] The guide vertical pipe 22 at the bottom of the inner cavity of the dust collection plate 30 vertically guides the airflow intercepted by the separation filter plate 19 to the air inlet of the fan 18, forming a straight airflow channel, reducing energy loss and vibration noise. The guide horizontal pipes 23 on both sides of the guide vertical pipe 22 collect the airflow through the surface air inlet holes 24, forming a horizontal diffusion air inlet mode, expanding the effective air inlet area, and improving the uniformity of hair adsorption of the separation filter plate 19.

[0043] The scraper 27 is slidably connected to the guide rod 25 via the ring plate 26. After the external force is released, the reset spring 29 drives the scraper 27 to automatically return to its original position. This mechanism enables a single manual operation to complete the bidirectional cleaning action, scraping hair in the outgoing direction and resetting in the return direction, reducing repeated operation steps and avoiding indentations on the surface of the filter screen 3.

[0044] The positioning protrusion 20 and the positioning groove 21 are seamlessly connected to eliminate the gap at the connection between the filter screen 3 and the dust collection plate 30, preventing unfiltered airflow from bypassing the filter screen 3 and directly entering the dust collection plate 30, thus ensuring the reliability of the dual-stage filtration system. The outer cover plate added to the surface of the handle 28 slides and fits against the surfaces of the front shell 2 and the rear shell 16, preventing outside air from entering the purifier through the moving groove of the handle 28.
