[0034] The current car air purifiers have limited effect in removing static electricity and usually require the installation of additional equipment to achieve the sterilization function. This not only increases production costs, but also occupies limited space in the car.

[0035] In order to solve this technical problem, the present invention proposes a vehicle-mounted air purifier.

[0036] See also Figure 1 , Figure 2 and Figure 4In one embodiment of the present invention, the vehicle-mounted air purifier comprises a housing 100, a mounting seat 200 and a dual ion generating mechanism 300. The housing 100 encloses a receiving space 103 having an air inlet 101 and an air outlet 102, and the air inlet 101 and the air outlet 102 are arranged at a vertical interval; the mounting seat 200 is accommodated in the receiving space 103 and is arranged between the air inlet 101 and the air outlet 102. A ventilation hole 201 is formed on the mounting seat 200, and the air inlet 101 and the air outlet 102 are connected through the ventilation hole 201; the dual ion generating mechanism 300 is arranged on the mounting seat 200 corresponding to the position of the ventilation hole 201, and the dual ion generating mechanism 300 is used to remove static electricity and sterilize in the air.

[0037] Specifically, the vehicle-mounted air purifier is composed of a housing 100, a mounting base 200 and a dual ion generating mechanism 300. The housing 100 encloses a receiving space 103 having an air inlet 101 and an air outlet 102. The air inlet 101 and the air outlet 102 are arranged at intervals in the vertical direction, thereby ensuring the effective flow of air. The provision of the receiving space 103 allows the air to encounter less resistance during the entry process, greatly improving the air circulation efficiency.

[0038] The mounting seat 200 is located in the accommodating space 103 of the housing 100 and is positioned between the air inlet 101 and the air outlet 102. The ventilation holes 201 arranged thereon enable the air inlet 101 and the air outlet 102 to be effectively connected, so that the air can quickly flow through the ventilation holes 201 to the air outlet 102, thereby ensuring the rapid circulation of air in the vehicle. The arrangement of the ventilation holes 201 can not only optimize the path of air circulation, but also improve the air processing efficiency of the dual ion generating mechanism 300.

[0039] The dual ion generating mechanism 300 is located at the corresponding position of the vent 201 and is responsible for removing static electricity and sterilizing in the air. During the air flow, the dual ion generating mechanism 300 can effectively release negative ions, thereby neutralizing the static electricity in the air and reducing the potential impact of static electricity on items and equipment in the vehicle. In addition, positive ions can also be released. Positive ions interact with bacteria and viruses in the air, destroying their living environment and achieving a sterilization effect. This allows the vehicle-mounted air purifier to simultaneously meet the functions of static electricity removal and sterilization without adding additional equipment, reducing production costs, and reducing the volume of the overall equipment to better adapt to the space inside the vehicle.

[0040] In addition, conventional air purifiers mostly use separate devices to achieve sterilization and static removal, resulting in problems such as large size and heavy weight of the equipment. The present invention can integrate various functions into a relatively compact structure by directly integrating the dual ion generating mechanism 300 on the mounting base 200, which not only simplifies the manufacturing process, but also improves the overall reliability of the equipment.

[0041] In the technical solution provided by the present invention, the problem of limited static electricity removal effect and insufficient sterilization efficiency in the prior art is effectively solved through the dual ion generating mechanism 300. The dual ion generating mechanism 300 releases negative ions and positive ions during the air purification process, which can quickly neutralize static electricity in the air, and effectively remove bacteria and viruses to ensure the cleanliness and safety of the air in the car. It not only reduces the dependence on traditional separate devices and reduces production costs, but also optimizes the overall structure of the equipment and improves space utilization. In addition, the size of the vehicle-mounted air purifier is further reduced, which is more suitable for the limited space in the car. While greatly improving the air quality in the car, it also improves the user's experience of the driving environment.

[0042] Continue to refer to Figure 1 and Figure 2 , and refer to Figure 7 In an embodiment of the present invention, the dual ion generating mechanism 300 includes a negative ion generating module 310, a positive ion generating module 320 and a control module 330, and the negative ion generating module 310 and the positive ion generating module 320 are both electrically connected to the control module 330; the negative ion generating module 310 and the positive ion generating module 320 each include at least one discharge needle, and the discharge needle of the negative ion generating module 310 and the discharge needle of the positive ion generating module 320 are both arranged on the mounting base 200 corresponding to the position of the ventilation hole 201.

[0043] Specifically, the negative ion generating module 310 and the positive ion generating module 320 are both electrically connected to the control module 330 to ensure information transmission and operation coordination between the modules. The control module 330 is responsible for regulating and managing the working states of the negative ion generating module 310 and the positive ion generating module 320, thereby optimizing the release efficiency and release timing of the ions, so that the negative ion generating module 310 and the positive ion generating module 320 do not work at the same time, avoiding electrical neutralization, so as to achieve static electricity removal and sterilization effects.

[0044] More specifically, the negative ion generating module 310 and the positive ion generating module 320 each include at least one discharge needle, and the discharge needle of the negative ion generating module 310 and the discharge needle of the positive ion generating module 320 are both correspondingly arranged at the position of the ventilation hole 201. When the air passes through the ventilation hole 201, the negative ions and the positive ions can effectively come into contact with the flowing air, quickly neutralize the static electricity in the air, and kill the bacteria and viruses in the air. The air in the car is made fresh and safe, and the comprehensive performance of the vehicle-mounted air purifier in terms of static electricity removal and sterilization is effectively improved.

[0045] As an optional implementation, the discharge needle of the negative ion generation module 310 releases negative ions through electric current and mixes with the flowing air, thereby neutralizing the positive charge in the air and reducing the accumulation of static electricity. The discharge needle of the positive ion generation module 320 releases positive ions to enhance the oxidizing property in the airflow so as to effectively kill bacteria and viruses. The two work together to significantly improve the air quality in the car.

[0046] As another optional implementation, according to the signal adjustment of the control module 330, the discharge period of the negative ion and positive ion generating module 320 can be adjusted according to the real-time monitoring data of the air quality in the vehicle, so as to more intelligently meet the air purification needs in different situations. It can ensure that a better air treatment effect can be achieved in various usage scenarios, thereby enhancing the user experience.

[0047] Continue to refer to Figure 7 In an embodiment of the present invention, the negative ion generating module 310 and the positive ion generating module 320 are both electrically connected to the high voltage power supply module 400; the dual ion generating mechanism 300 also includes at least one electric field sensing module 800, at least one electric field sensing module 800 is installed on the mounting seat 200 at intervals along the horizontal direction, at least one electric field sensing module 800 is electrically connected to the control module 330, and at least one electric field sensing module 800 is used to sense the amount of charge in the accommodating space 103 and generate an induction signal accordingly; the control module 330 is used to control the negative ion generating module 310 and / or the positive ion generating module 320 to start according to the position of the electric field sensing module 800 corresponding to the induction signal, and correspondingly discharge the discharge needle of the negative ion generating module 310 and / or the discharge needle of the positive ion generating module 320.

[0048] It should be noted that the electric field sensing module 800 can be an electric field strength sensor or an electrostatic sensor such as an electrostatic voltage sensor (ESD sensor) in the prior art. The control module 330 includes a microcontroller (MCU), an ADC converter and a PWM controller in the prior art (used to use a PWM (pulse width modulation) signal to adjust the output power of the high-voltage power supply module 400, thereby controlling the discharge intensity of the discharge needle).

[0049] Specifically, the discharge needle of the negative ion generation module 310 and the discharge needle of the positive ion generation module 320 are both electrically connected to the high voltage power supply module 400. The negative ion generation module 310 and the positive ion generation module 320 both obtain power support through the high voltage power supply module 400 to provide the required high voltage excitation for the discharge needle to release negative ions and positive ions.

[0050] More specifically, multiple electric field sensing modules 800 are installed on the mounting base 200 at intervals along the horizontal direction, and the multiple electric field sensing modules 800 are electrically connected to the control module 330 respectively. The electric field sensing modules 800 are used to sense the amount of charge in the accommodation space 103, thereby providing a real-time charge detection function in the vehicle environment, and can timely measure the changes in the electric field in the vehicle and generate corresponding sensing signals. The control module 330 can monitor the charge status in the vehicle in real time based on the feedback of these sensing signals.

[0051] As an optional implementation, when the electric field sensing module 800 senses that the amount of static charge in the accommodation space 103 exceeds a preset threshold, the control module 330 will issue instructions to the negative ion generating module 310 and / or the positive ion generating module 320 to start the corresponding module to release ions. Specifically, the control module 330 can select an appropriate discharge needle for discharge according to the intensity and characteristics of the sensing signal, thereby quickly neutralizing the excess static charge and ensuring a stable in-vehicle environment. Among them, the preset threshold is 200V to 300V. For conventional static charges inside the vehicle, a preset threshold of 200V to 300V can effectively neutralize static electricity without frequently triggering the system.

[0052] As another optional implementation, if the electric field sensor module 800 senses that the charge in the accommodation space 103 is too low, the control module 330 can choose to stop the release of negative ions or positive ions, avoiding unnecessary energy consumption and the problem of excessive ions, and maintaining the efficient controllability of ion generation. This adjustment mechanism enables the vehicle air purifier to dynamically adjust its working state according to the actual charge situation, thereby improving the accuracy and effectiveness of purification.

[0053] Continue to refer to Figure 1 and Figure 2 , and refer to Figure 3 In an embodiment of the present invention, the vehicle-mounted air purifier further includes a cleaning mechanism 500, which is mounted on the mounting seat 200, and the discharge needle of the negative ion generating module 310 and the discharge needle of the positive ion generating module 320 are both arranged opposite to the cleaning mechanism 500, and the discharge needle of the negative ion generating module 310 and the discharge needle of the positive ion generating module 320 can move relative to the cleaning mechanism 500 in a horizontal direction, so that the cleaning mechanism 500 can contact the discharge needle of the negative ion generating module 310 and the discharge needle of the positive ion generating module 320.

[0054] Specifically, the cleaning mechanism 500 is mounted on the mounting base 200 and is arranged opposite to the discharge needles of the negative ion generating module 310 and the positive ion generating module 320. Specifically, the discharge needles of the negative ion generating module 310 and the discharge needles of the positive ion generating module 320 can move relative to the cleaning mechanism 500 in the horizontal direction, thereby ensuring that the cleaning mechanism 500 can contact the discharge needles when working, and effectively remove dirt and dust on the surface thereof.

[0055] More specifically, when the vehicle-mounted air purifier is working, the cleaning mechanism 500 will automatically move according to a preset program or sensor signal and contact the surface of the discharge needle, and can remove dust and dirt accumulated on the discharge needle when the dual ion generating mechanism 300 is working, ensuring that the effect of ion release is not affected.

[0056] As an optional embodiment, the cleaning mechanism 500 can be configured to automatically move to the discharge needle position at a specific time interval, remove dust and dirt by rubbing the surface of the discharge needle, thereby keeping the needle tip clean. At the same time, the activity of the cleaning mechanism 500 does not affect the release process of negative ions and positive ions, ensuring that the purifier continues to work efficiently.

[0057] As another optional embodiment, the cleaning mechanism 500 can be combined with the electric field sensing module 800. When the electric field sensing module 800 detects that the charge response of the discharge needle becomes weaker, indicating that the efficiency of current release is reduced, the cleaning mechanism 500 will be triggered to clean to restore the optimal working state of the dual ion generating mechanism 300. This automatic cleaning mechanism not only improves the convenience of use of the device, but also significantly extends the effective service life of the ion generating module.

[0058] This embodiment uses the cleaning mechanism 500 to enable the vehicle-mounted air purifier to automatically clean the discharge needles of the negative ion generating module 310 and the positive ion generating module 320, thus overcoming the cleaning difficulty in the prior art. The continuous effectiveness of the ion release of the dual ion generating mechanism 300 is ensured, the working efficiency of the air purifier is improved, and thus the air quality and user experience in the vehicle are further improved. At the same time, the cleaning mechanism 500 also makes the equipment maintenance simpler, ensuring its long-term and reliable use.

[0059] In an embodiment of the present invention, the cleaning mechanism 500 includes a first sliding seat 510, a cleaning brush 520 and a first driving member 530. The discharge needle of the negative ion generating module 310 and the discharge needle of the positive ion generating module 320 are both arranged opposite to the first sliding seat 510. The first sliding seat 510 can be slidably installed on the mounting seat 200 in a horizontal direction. The cleaning brush 520 can be rotatably installed on the side of the first sliding seat 510 facing the discharge needle of the negative ion generating module 310 and the discharge needle of the positive ion generating module 320. The first driving member 530 is installed on the mounting seat 200. The output end of the first driving member 530 is connected to the first sliding seat 510. The first driving member 530 is electrically connected to the control module 330. The control module 330 is also used to control the first driving member 530 to drive the first sliding seat 510 to move in the horizontal direction so that the cleaning brush 520 contacts the discharge needle of the negative ion generating module 310 and the discharge needle of the positive ion generating module 320.

[0060] During the operation of the vehicle-mounted air purifier, the discharge needle is prone to gradually reduce its ionization effect due to the deposition of dust and other pollutants, resulting in a decrease in static removal and sterilization efficiency. Existing equipment lacks an automatic cleaning mechanism and often requires manual intervention for maintenance and cleaning, which increases the complexity of use and the burden on users. The cleaning mechanism 500 includes a first sliding seat 510, a cleaning brush 520 and a first driving member 530. First, the first sliding seat 510 is arranged relative to the discharge needle of the negative ion generating module 310 and the discharge needle of the positive ion generating module 320 to ensure effective contact during the cleaning process. The first sliding seat 510 can slide freely on the mounting seat 200 in the horizontal direction, so that the cleaning brush 520 can more flexibly contact the discharge needle of the negative ion generating module 310 and the discharge needle of the positive ion generating module 320.

[0061] More specifically, the first sliding seat 510 allows the cleaning brush 520 to fully cover the surface when it approaches and contacts the discharge needle of the negative ion generating module 310 and the discharge needle of the positive ion generating module 320. The cleaning brush 520 is rotatably mounted on the first sliding seat 510. When the first sliding seat 510 moves, the cleaning brush 520 rotates relatively, thereby enhancing its cleaning effect and improving cleaning efficiency.

[0062] As an optional embodiment, the first driving member 530 is mounted on the mounting base 200 and is electrically connected to the control module 330. The control module 330 can control the operation of the first driving member 530 through a preset program or a real-time feedback signal to drive the first sliding base 510 to slide left and right. Each time the air purifier is started, the cleaning mechanism 500 can automatically adjust its position to contact the discharge needle and perform a cleaning action, thereby ensuring the continued effectiveness of the discharge needle.

[0063] As another optional implementation, when the electric field sensor module 800 detects that the performance of the discharge needle has decreased, the control module 330 can start the first driving member 530 to move the cleaning brush 520 and clean it. The self-rotation function of the cleaning brush 520 can more effectively remove the pollutants on the discharge needle, keep the dual ion generating mechanism 300 in the best working state, and ensure that the vehicle-mounted air purifier is always in efficient operation.

[0064] As another optional embodiment, the first sliding seat 510 is a first rack. The first rack is slidably installed in the housing 100 along the horizontal direction, and the first driving member 530 is engaged with the first rack through the first gear. The first driving member 530 drives the first gear to rotate and drives the first rack to slide back and forth in the horizontal direction, thereby driving the cleaning brush 520 to contact and clean the discharge needles of the negative ion generating module 310 and the discharge needles of the positive ion generating module 320.

[0065] In an embodiment of the present invention, the dual ion generating mechanism 300 also includes a second sliding seat and a second driving member. The second sliding seat is arranged opposite to the cleaning mechanism 500. The discharge needle of the negative ion generating module 310 and the discharge needle of the positive ion generating module 320 are both installed on the side of the second sliding seat facing the cleaning mechanism 500. The second driving member is installed on the mounting seat 200. The output end of the second driving member is connected to the second sliding seat. The second driving member is electrically connected to the control module 330. The control module 330 is also used to control the second driving member to drive the second sliding seat to move in the horizontal direction according to the position information, so that the cleaning brush 520 contacts the discharge needle of the negative ion generating module 310 and the discharge needle of the positive ion generating module 320.

[0066] Specifically, the second sliding seat is arranged opposite to the cleaning mechanism 500, and the discharge needle of the negative ion generating module 310 and the discharge needle of the positive ion generating module 320 are both installed on the side of the second sliding seat facing the cleaning mechanism 500, ensuring that the cleaning brush 520 can effectively contact the discharge needle of the ion generating module and the discharge needle of the positive ion generating module 320 during the cleaning process.

[0067] More specifically, similar to the first driving member 530, the second driving member can drive the second sliding seat to move on the horizontal plane. Since the cleaning process is the same, this embodiment only replaces the active displacement of the cleaning mechanism 500 with the active displacement of the dual ion generating mechanism 300, so it will not be repeated.

[0068] As an optional embodiment, an insulating base is provided on the side of the second sliding seat facing the cleaning mechanism 500, and the discharge needle of the negative ion generating module 310 and the discharge needle of the positive ion generating module 320 are both installed on the insulating base.

[0069] As another optional embodiment, the second sliding seat is a second rack. The second rack is slidably installed in the housing 100 along the horizontal direction, and the second driving member is engaged with the second rack through the second gear.

[0071] Specifically, the light source 600 is installed in the housing 100 and corresponds to the position of the air inlet 101. The main function of the light source 600 is to provide lighting and help the user to intuitively understand the dust in the air at the air inlet 101.

[0072] The light source 600 makes the air in the air inlet 101 area more visible by lighting, so that the user can observe the dust particles suspended in the air, which helps to monitor the air quality in real time and provide visual feedback to the user.

[0073] It should be noted that the light source 600 may use a lamp with adjustable brightness to ensure that the dust situation can be clearly displayed under different light conditions.

[0074] This embodiment not only enhances the user experience, but also can remind the user to replace or clean the filter assembly 720 in time when the air quality is poor.

The air purification mechanism 700 is accommodated in the accommodation space 103 , and the air purification mechanism 700 is installed between the mounting seat 200 and the air outlet 102 .

[0076] Specifically, the air purification mechanism 700 is used to ensure efficient air purification. The air purification mechanism 700 is accommodated in the accommodation space 103 and installed between the mounting seat 200 and the air outlet 102. It ensures that the air that has passed through the cleaning mechanism 500 and purified can flow quickly into the vehicle, providing a fresher breathing environment for the user.

[0077] More specifically, the air purification mechanism 700 is located between the mounting base 200 and the air outlet 102, ensuring that the air can flow naturally when passing through the purification mechanism, forming a good air circulation, so that the incoming air is processed by the air purification mechanism 700 while increasing the flow rate, thereby ensuring the air quality in the vehicle.

[0078] Please continue reading Figure 1 , and see Figure 6 In an embodiment of the present invention, the air purification mechanism 700 includes a fan 710 and a filter assembly 720 . The fan 710 is installed between the mounting base 200 and the air outlet 102 , and the filter assembly 720 is installed on the housing 100 at a position corresponding to the air outlet 102 .

[0079] Specifically, the installation position of the filter assembly 720 ensures that the air after static elimination and cleaning can be further filtered to remove fine particles and other impurities.

[0080] It should be noted that the filter component 720 can use multi-layer filter materials in the prior art, such as a HEPA filter or an activated carbon filter, to effectively capture tiny particles and harmful gases.

[0081] More specifically, air enters from the air inlet 101, passes through the ventilation hole 201 of the mounting base 200, and is first eliminated by the dual ion generating mechanism 300 to remove static electricity and sterilize. Then, the air that has undergone preliminary treatment continues to be further purified by the air purification mechanism 700, and finally is finally filtered by the filter assembly 720 to ensure that the air discharged from the air outlet 102 is clean and fresh.

[0082] In an embodiment of the present invention, there are multiple air outlets 102, and the multiple air outlets 102 are arranged on the side wall of the shell 100 at intervals along the circumference of the shell 100; the bottom wall of the shell 100 is provided with multiple installation openings, and the number of the installation openings is consistent with the number of the air outlets 102 and is arranged one-to-one; the filter assembly 720 includes multiple filter elements 721, and the number of the filter elements 721 is consistent with the number of the installation openings and is arranged one-to-one, and each filter element 721 is detachably connected to its corresponding installation opening.

[0083] Specifically, there are multiple air outlets 102 , and the multiple air outlets 102 are distributed on the side wall along the circumference of the shell 100 at intervals, so as to ensure that the purified air is discharged evenly and achieve a better air circulation effect.

[0084] The bottom wall of the housing 100 is provided with a plurality of mounting ports, the number of which is consistent with the number of the air outlets 102, and they are arranged in a one-to-one correspondence. Each mounting port is used to install a corresponding filter assembly 720. The filter assembly 720 includes a plurality of filter elements 721, the number of which is consistent with the number of the mounting ports, and each filter element 721 is detachably connected to its corresponding mounting port for easy installation and replacement. The filter element 721 of each air outlet 102 ensures that each air flow is fully filtered before being discharged, thereby improving the air purification efficiency. In addition, the detachable filter element 721 is convenient for the user to clean or replace, thereby maintaining good performance and extending the life of the equipment.
