Description

Technical Field

[0001] This application relates to the field of vehicle-mounted filtration devices, and in particular to an air filtration device for a vehicle-mounted air purifier. Background Technology

[0002] With the rapid development of the global economy and the significant improvement of residents' living standards, private cars have become the main means of transportation for families. In daily use, cars are relatively enclosed spaces with low utilization rates of their interior space. Moreover, in most cases, car windows and doors are closed, resulting in poor air circulation and the generation of bacteria and odors, which greatly reduces the quality of air inside the car.

[0003] In car usage scenarios, the air inside the car is usually purified by opening the windows and using the external air circulation while driving. However, harmful gases and dust from outside can easily enter the car and cannot remove harmful substances from the small space inside the car. This not only seriously threatens the respiratory health of the driver and passengers, but long-term exposure may also cause chronic diseases, greatly reducing the user experience and comfort during the driving process, and has obvious shortcomings. Utility Model Content

[0004] To improve user comfort while driving, this application provides an air filtration device for an in-vehicle air purifier.

[0005] The air filtration device for a vehicle air purifier provided in this application adopts the following technical solution:

[0006] An air filtration device for a car air purifier includes a base placed in the cup holder of a car. A mounting bracket is mounted on the base, and a power module, a supplementary light bulb, and a photocatalytic filter are sequentially arranged on the mounting bracket away from the base. A lower housing is mounted on the base, covering the photocatalytic filter and the mounting bracket. An upper housing is detachably connected to the lower housing, and a fan is housed within the upper housing. A cover is detachably connected to the upper housing. Multiple air inlets are circumferentially opened on the lower housing, and multiple air outlets are evenly distributed circumferentially on the outer periphery of the cover. The power module provides electrical energy to the supplementary light bulb and the fan.

[0007] By adopting the above technical solution, before driving, the user places the base in the car's cup holder. While driving, the power module provides power to the fan and supplementary light bulbs. The fan rotates and draws polluted air from inside the car into the lower housing through the air inlet. The supplementary light bulbs provide illumination for the photocatalytic filter. When air flows through the photocatalytic filter, the filter produces a catalytic degradation function under the light, effectively decomposing bacteria, odor molecules, and harmful substances such as formaldehyde and benzene in the air, converting them into harmless substances such as carbon dioxide and water, thus purifying the air. The purified clean air is then discharged into the car through the air outlet of the upper housing by the fan, forming a continuous and effective air circulation and purification process, thereby effectively improving the air quality inside the car and enhancing the user's comfort while driving.

[0008] Optionally, the mounting bracket is provided with a negative ion module, which is located on the side of the photocatalytic filter near the base, and the power module is electrically connected to the negative ion module.

[0009] By adopting the above technical solution, when air is introduced through the air inlet, the air first passes through the negative ion module. The negative ions generated by the negative ion module combine with the positively charged harmful particles in the air, causing these particles to settle due to their increased weight. This effectively removes suspended pollutants from the air, reduces the filtration load of the photocatalytic filter, and thus improves the filtration effect of the photocatalytic filter.

[0010] Optionally, the mounting bracket is equipped with a PM2.5 module and a formaldehyde module, which are electrically connected to the power module via a control system.

[0011] By adopting the above technical solution, when the PM2.5 module and formaldehyde module detect that the PM2.5 or formaldehyde concentration exceeds the standard, the control system automatically controls the power module to turn on and start the purification process; when the air is purified to meet the requirements, the control system controls the power module to turn off and terminate the purification process. In this way, the purification process is intelligently and automatically controlled, eliminating the need for manual operation and further improving the convenience and comfort of users.

[0012] Optionally, the lower housing is provided with a mounting groove, and a fragrance module is detachably connected to the mounting groove via a magnetic module.

[0013] By adopting the above technical solution, the fragrance released by the fragrance module can effectively mask residual odors in the car during the air purification process. It works in synergy with the purification function of the photocatalytic filter to further purify the air and improve the comfort of passengers. At the same time, users can quickly replace the depleted fragrance module through the magnetic module, improving the applicability of the filter device.

[0014] Optionally, the upper housing is provided with a display screen, which is used to display formaldehyde concentration, PM2.5 concentration and fan speed parameters.

[0015] By adopting the above technical solution, the display screen allows users to promptly monitor the air quality inside the vehicle and the operation of the filtration device.

[0016] Optionally, the bottom surface of the base is provided with a support seat, and the support seat is evenly provided with multiple support grooves in the circumference. Each support groove is slidably connected with an abutment block. The abutment surface of the abutment block is arc-shaped. Each support groove is provided with a clamping spring. One end of the clamping spring is provided on the inner side wall of the support groove, and the other end is provided on the abutment block. The elastic force of the clamping spring pushes the abutment block to abut against the inner side wall of the water tank. The support seat is provided with a drive assembly that drives the multiple abutment blocks to move into the support groove.

[0017] By adopting the above technical solution, before placement, the worker first moves multiple abutment blocks into the support groove using the drive component. Then, the base is placed in the water cup slot and the control of the drive component is canceled. Under the action of the elastic spring, the abutment blocks are automatically pushed against the inner wall of the water tank, thereby achieving effective support for the filter device in the water cup slot. This reduces the possibility of the base shaking and shifting due to bumps during vehicle travel, improves the stability of the air purification process, and makes the filter device suitable for water cup slots of different sizes, thus improving the applicability of the filter device.

[0018] Optionally, the outer periphery of the support base is provided with a rotating groove, and the driving assembly includes a rotating ring rotatably connected in the rotating groove. The rotating ring is provided with connecting ropes corresponding to the plurality of abutment blocks one by one, and the ends of the connecting ropes extend into the support groove and are disposed on the abutment blocks.

[0019] By adopting the above technical solution, the worker rotates the rotating ring, which pulls the connecting rope to move within the rotating groove. Since the total length of the connecting rope does not change, the movement of the connecting rope will pull the abutment block to move into the support groove, thus making it easier for the worker to place the base into the cup groove and improving the user's ease of operation.

[0020] Optionally, each of the support grooves is provided with a guide post, the abutment block is provided with a guide hole that slides with the guide post, and the clamping spring is sleeved on the outer surface of the guide post.

[0021] By adopting the above technical solution, the sliding fit between the guide post and the guide hole provides guidance and stable support for the sliding of the abutment block, effectively reducing the possibility of the abutment block shifting or tilting during movement, ensuring that the abutment block can smoothly abut against the inner wall of the cup holder along a straight line, making the base more evenly stressed and improving the stability after installation.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This embodiment of the application sets up a power module, supplementary light beads, and a photocatalytic filter. The power module provides power to the fan and supplementary light beads. The fan rotates and draws the polluted air in the car into the lower housing through the air inlet. The supplementary light beads provide light conditions for the photocatalytic filter. When the air flows through the photocatalytic filter, the photocatalytic filter produces a catalytic degradation function under the action of light, thereby purifying the air. The purified clean air is then discharged into the car through the air outlet of the upper housing by the fan, forming a continuous and effective air circulation purification process, thereby effectively improving the air quality in the car and improving the comfort of the user when driving and riding in the car.

[0024] 2. This application sets up a drive component and multiple abutment blocks. The clamping spring automatically pushes the abutment blocks against the inner wall of the water tank under the action of elasticity, thereby achieving effective support of the filter device in the water cup tank. This reduces the possibility of the base shaking and shifting due to bumps during vehicle operation, improves the stability of the air purification process, and makes the filter device suitable for water cup tanks of different sizes, thus improving the applicability of the filter device.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses an air filtration device for a vehicle air purifier.

[0032] Reference Figure 1 and Figure 2 An air filtration device for a car air purifier includes a base 1, a lower housing 2 detachably connected to the base 1, an upper housing 3 detachably connected to the end of the lower housing 2 away from the base 1, and a cover 31 detachably connected to the end of the upper housing 3 away from the lower housing 2. In this embodiment, the detachable connections are all achieved through the snap-fit ​​engagement of elastic buckles in the prior art. The base 1, upper housing 3, lower housing 2, and cover 31 together form the outer shell of the filtration device. Before driving, the user places the filtration device in the car's cup holder.

[0033] Reference Figure 1 and Figure 2 A mounting bracket 4 is fixedly connected to the base 1. The mounting bracket 4 is equipped with a power module 5, a supplementary light bulb 6 and a photocatalytic filter element 7 in sequence along the direction away from the base 1. The supplementary light bulb 6 provides light conditions for the catalytic reaction of the photocatalytic filter element 7. The lower housing 2 covers the outer surface of the photocatalytic filter element 7 and the mounting bracket 4. A fan 8 is installed inside the upper housing 3. The power module 5 is used to provide power to the supplementary light bulb 6 and the fan 8.

[0034] Reference Figure 1 and Figure 2 The mounting bracket 4 is fixedly installed with a negative ion module 9, a formaldehyde module 10 and a PM2.5 module 11. The negative ion module 9 is located on the side of the photocatalytic filter 7 near the base 1. The power module 5 is electrically connected to the negative ion module 9, the formaldehyde module 10 and the PM2.5 module 11. The PM2.5 module 11 and the formaldehyde module 10 are electrically connected to the power module 5 through a control system.

[0035] Reference Figure 1 and Figure 2 The lower housing 2 has multiple air inlets 21, which are evenly distributed in an array around the surface of the lower housing 2. When the filter device is placed inside the water cup, the lowest air inlet 21 is higher than the height of the water cup. The outer periphery of the cover 31 has multiple air outlets 311 evenly distributed at equal intervals.

[0036] When PM2.5 module 11 and formaldehyde module 10 detect that PM2.5 or formaldehyde concentration exceeds the standard, the control system automatically controls the power module 5 to turn on. The power module 5 drives the fan 8, the supplementary light column and the negative ion module 9 to run. The fan 8 rotates and draws the polluted air in the vehicle into the lower housing 2 through the air inlet 21. The polluted air first comes into contact with the negative ion module 9. The negative ions generated by the negative ion module 9 combine with the positively charged harmful particles, causing these particles to settle due to the increase in weight, thereby removing suspended pollutants in the air.

[0037] After initial filtration, the air flows to the photocatalytic filter element 7. Under the action of light, the photocatalytic filter element 7 generates a catalytic degradation function, which can effectively decompose bacteria, odor molecules, and harmful substances such as formaldehyde and benzene in the air, converting them into harmless substances such as carbon dioxide and water, thereby purifying the air. The purified clean air is then discharged into the car through the air outlet 311 of the upper housing 3 by the fan 8, forming a continuous and effective air circulation purification process, thereby effectively improving the air quality in the car and improving the comfort of the user when driving. When the air in the car is purified to the standard, the control system controls the power module 5 to shut down, and the purification process ends.

[0038] Reference Figure 1 and Figure 2 The top of the upper housing 3 is equipped with a display screen 12, which allows users to obtain formaldehyde concentration, PM2.5 concentration and fan speed parameters, so that users can keep track of the air quality inside the vehicle and the operation of the filtration device.

[0039] Reference Figure 1 and Figure 2 The lower housing 2 has an installation groove 22 along its length. A fragrance module 14 is detachably connected to the installation groove 22 via a magnetic suction module 13. During the air purification process, the fragrance released by the fragrance module 14 can effectively mask the residual odor in the car. It works in synergy with the purification function of the photocatalytic filter 7 to further purify the air and improve the comfort of the passengers.

[0040] The implementation principle of the air filtration device of the vehicle air purifier in this application embodiment is as follows: When driving, the power module 5 provides power to the fan 8 and the supplementary light bulb 6. The fan 8 rotates and draws the polluted air in the car into the lower housing 2 through the air inlet 21. The supplementary light bulb 6 provides light conditions for the photocatalytic filter 7. When the air flows through the photocatalytic filter 7, the photocatalytic filter 7 produces a catalytic degradation function under the action of light, which can effectively decompose bacteria, odor molecules and harmful substances such as formaldehyde and benzene in the air, and convert them into harmless substances such as carbon dioxide and water, thereby purifying the air. The purified clean air is then discharged into the car through the air outlet 311 of the upper housing 3 by the fan 8, forming a continuous and effective air circulation purification process, thereby effectively improving the air quality in the car and improving the comfort of the user when driving. Example

[0041] Reference Figure 3 and Figure 4 The difference between this embodiment and Embodiment 1 is that a support base 15 is fixedly installed on the bottom surface of the base 1. The support base 15 is cylindrical and has a plurality of support grooves 16 evenly distributed around its circumference. In this embodiment, there are three support grooves 16. Each support groove 16 is slidably connected to an abutment block 161, and the abutment surface of the abutment block 161 is arc-shaped.

[0042] Reference Figure 3 and Figure 4 Each support groove 16 is fixedly installed with a guide post 162. The guide post 162 is parallel to the radial direction of the support base 15. The abutment block 161 is provided with a guide hole (not shown in the figure) that slides with the guide post 162. A clamping spring 163 is sleeved on the outer surface of the guide post 162. One end of the clamping spring 163 is fixedly connected to the inner wall of the support groove 16, and the other end is fixedly connected to the abutment block 161. The elastic force of the clamping spring 163 pushes the abutment block 161 to abut against the inner wall of the water tank.

[0043] Reference Figure 3 and Figure 4 A rotating groove 17 is provided on the outer periphery of the support base 15. The rotating groove 17 is located above the support groove 16. A drive assembly 18 is provided inside the support base 15. Specifically, the drive assembly 18 includes a rotating ring 181 rotatably connected in the rotating groove 17. A connecting ring (not shown in the figure) is fixedly connected to the rotating ring 181. A connecting groove (not shown in the figure) is provided on the inner side wall of the rotating groove 17 to rotatably cooperate with the connecting ring. A connecting rope 182 corresponding to a plurality of abutment blocks 161 is fixedly connected to the rotating ring 181. The end of each connecting rope 182 extends into the support groove 16 and is fixedly connected to the abutment block 161.

[0044] The implementation principle of Example 2 is as follows: Before placement, the worker rotates the rotating ring 181, which pulls the connecting rope 182 to move within the rotating groove 17. Since the total length of the connecting rope 182 does not change, the movement of the connecting rope 182 will pull the abutment block 161 to move into the support groove 16. At this time, the worker places the base 1 in the water cup groove and then releases the force on the rotating ring 181. Under the action of the elastic force, the retaining spring 163 automatically pushes the abutment block 161 to abut against the inner wall of the water tank, thereby achieving effective support of the filter device in the water cup groove. This reduces the possibility of the base 1 shaking and shifting due to bumps during vehicle travel, improves the stability of the air purification process, and makes the filter device suitable for water cup grooves of different sizes, thus improving the applicability of the filter device.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
