[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] See attached Figure 1As shown, an embodiment of the utility model discloses a vehicle-mounted air purifier, including a housing 1, a filter 2, a fan 3, a petal-shaped opening and closing purification hole 4, a controller 5, a top screen 6, a negative ion generator 7, an information sensor device 8 and a battery 9.

[0037] Among them, refer to the attached Figure 2 As shown, the fan 3, the petal-shaped opening and closing purification hole 4, the top screen 6, the negative ion generator 7, the information sensor device 8, and the battery 9 are all electrically connected to the controller 5. Figure 1 As shown, the top screen 6 is movably installed on the top of one end of the casing 1; below the top screen 6 is the opening and closing purification hole 4; and the opening and closing purification hole 4, the filter 2, the fan 3, the negative ion generator 7, the information sensor device 8, the controller 5 and the battery 9 are installed in the casing 1 in sequence from top to bottom.

[0038] Specifically, the fan 3 is used to circulate and draw air, so that the air passes through the filter 2 for purification; the controller 5 is responsible for controlling the operation of the entire air purifier, monitoring the air quality, and adjusting the speed of the fan 3, the opening and closing state of the petal-shaped opening and closing purification hole 4 and the operation of the negative ion generator 7 as needed; the top screen 6 is an interactive display screen that is movably installed above the housing 1, which is used to display the current air quality information, operation mode and other related information; the negative ion generator 7 releases negative ions to effectively remove harmful substances such as bacteria, viruses, and odors in the air; the information sensor device 8 is used to monitor the data of the in-vehicle environment, and transmits signals such as air quality, temperature, and humidity to the controller, which processes the data and then controls the fan speed and the opening and closing state of the petal-shaped opening and closing purification hole; the battery 9 is used to power each component. In a specific implementation, for example, the controller uses a single-chip microcomputer STC89C52, which has the advantages of low power consumption and high performance.

[0039] In this embodiment, refer to the attached Figure 3 As shown, the housing 1 includes an upper housing and a lower housing, and the upper housing and the lower housing are slidably connected. When the two slide against each other, a fence-like air outlet is revealed, surrounding the body; the air outlet corresponds to the position of the petal-shaped opening and closing purification hole 4.

[0040] Specifically, the design of the petal-shaped opening and closing purification hole 4 not only makes it convenient for users to replace and clean the filter, but also ensures the sealing of the air purifier. The purification hole is opened when the air purifier is working and closed when it is not working, which can effectively protect the internal components, extend the service life of the air purifier, and improve the convenience of use and maintenance efficiency of the air purifier.

[0041] Working principle: The size and shape of the petal-shaped opening and closing purification hole have an important influence on air flow and noise generation. By rationally designing the size and shape of the hole, air flow can be optimized and turbulence and noise can be reduced. Appropriately reducing the size of the hole can limit the air flow and thus reduce noise. At the same time, using a suitable shape, such as a circular, oval or a specific special-shaped hole, can further improve the air flow characteristics and reduce noise.

[0042] Reference Figure 4a-4c As shown in the figure, its structural design draws on the natural shape of petals, and the petal-shaped contour is designed biomimetically. This contour can guide the air to flow more evenly through the inside of the purifier, reducing turbulence and noise. Drive mode: In order to adapt to different air flow requirements, a flexible opening and closing mechanism is designed. The opening and closing angles of the petals are controlled by the controller in an electric way to achieve dynamic adjustment of air flow and purification effect; the opening and closing state of the petals can also be automatically adjusted according to air quality, environmental conditions and user needs to achieve the best noise reduction effect. There are 3 opening and closing states, namely Figure 4a 30° opening and closing, Figure 4b 60° opening and closing Figure 4c 90° opening and closing.

[0043] In this embodiment, a charging port is provided on the lower housing, and is used with a 12V power adapter to ensure that the air purifier can continue to work even when the car is turned off. It can be used not only in the car, but also in other places where air purification is required.

[0044] In this embodiment, the housing 1 is made of flame-retardant ABS plastic and / or aluminum alloy material, which has good texture and durability, and combined with the electroplating process, the quality of the entire air purifier is effectively improved.

[0045] In this embodiment, the filter 1 is one or more of a HEPA filter, an activated carbon filter, a photocatalyst filter and an electrostatic filter.

[0046] Specifically, the HEPA filter (high-efficiency particulate air filter) has a prominent air purification function and can effectively remove PM2.5, smoke, dust and other fine particles in the air, with a filtration efficiency of up to 99.97%; the activated carbon filter has a prominent odor elimination function and can effectively remove harmful gases such as formaldehyde, benzene, TVOC (total volatile organic compounds) in the air; the photocatalyst filter has a prominent sterilization function, using ultraviolet rays to irradiate the surface of the photocatalyst to produce an oxidation reaction, which can decompose organic pollutants and bacteria; the electrostatic filter uses the principle of electrostatic adsorption to effectively capture and remove fine particles and dust in the air. According to the specific application requirements and air quality conditions, you can choose to use a single filter or combine multiple filters to achieve a more comprehensive and efficient air purification effect.

[0047] In this embodiment, the information sensing device 8 includes an optical dust sensor SM-PWM-01A, a temperature and humidity sensor DHT11, an audio and visual alarm module and a harmful gas sensor MQ5.

[0048] Specifically, harmful gas sensors can detect pollutant content in the air inside the car, such as PM2.5, CO2, TVOC, etc. By monitoring these indicators, the freshness and pollution level of the air inside the car can be evaluated; temperature and humidity sensors can measure the temperature and humidity inside the car, reflecting the comfort and environmental conditions inside the car; optical dust sensors can detect dust concentration inside the car, including fine particles and dust in the air, etc. The data of the dust sensor can provide the cleanliness and purification needs of the air inside the car; the sound and light alarm module can, for example, give voice or light reminders when the air quality inside the car exceeds the standard. By setting these information sensing devices and sending the collected data information to the controller, the wind speed and working mode can be adjusted intelligently.

[0049] For example, the working modes include: strong wind mode, weak wind mode, sleep mode and manual mode.

[0050] 1. Strong Wind Mode: In this mode, the purifier will run at maximum power. The petal-shaped opening and closing purification holes will be fully opened at 90° to maximize air flow. The fan speed will be adjusted to the highest to ensure that the air can be circulated and purified quickly.

[0051] This mode is suitable for situations where there are large amounts of pollutants in the air that need to be removed quickly.

[0052] 2. Low wind mode: In low wind mode, the power of the purifier will be reduced. The petal-shaped opening and closing purification holes will open at 60°, and the opening and closing degree will be reduced, thereby reducing the air flow. The fan speed will be lowered to produce a softer airflow.

[0053] This mode is suitable for situations where a quieter environment is required or strong airflow is not required.

[0054] 3. Sleep mode is usually designed for nighttime use.

[0055] The petal-shaped opening and closing purification hole opens at 30°, with extremely low noise level. The fan speed will be very low and may even change periodically to maintain air circulation but avoid disturbing sleep.

[0056] The top screen brightness will be turned off and dimmed to further reduce distractions. This mode is designed to provide a comfortable sleeping environment while still maintaining a certain air purification effect.

[0057] In another embodiment, the vehicle-mounted air purifier may also be provided with a wireless communication module, which is electrically connected to the controller 5 and connected to the remote terminal via wireless communication, that is, it can receive control instructions from the remote terminal and can also feedback relevant parameters of the real-time working status, such as wind speed or working mode adjustment instructions, air quality report feedback, control quality degradation warning and filter replacement reminder, etc., making user operation more convenient and improving the intelligence level of the air purifier.

[0058] The wireless communication module can be any one of a WIFI module, a public mobile communication network communication module, a Bluetooth module, and a near field communication module. The module is selected according to specific needs during actual application and is not specifically limited here. Among them, the public mobile communication network communication module can be a 2G, 3G, 4G, 5G communication module of various standards, and the near field communication module can be an NFC (Near Field Communication) module, etc.

[0059] The working principle of a vehicle-mounted air purifier provided by the embodiment of the utility model is as follows:

[0060] The user wakes up the purifier by touching the top screen or sending a control command through a remote terminal. The controller drives the motor to move the upper casing upward, opening the purification hole, and the fan, negative ion generator and information sensor device start working; the information sensor device collects the air data in the car in real time, and sends the collected information to the controller for processing to obtain an air quality report, and at the same time sends the air quality report to the top screen and the remote terminal for display; according to the air quality report, the controller automatically controls the fan to adjust the wind speed and working mode, or the user sends the wind speed and working mode adjustment command to the controller through the remote terminal for execution, thereby realizing the intelligent control and adjustment of the vehicle-mounted air purifier, which can not only provide a more convenient and comfortable use experience, but also improve the air purification effect in the car; the specific products produced are stylish and exquisite in appearance, combining aesthetics and practicality.

[0061] It is worth noting that the program used by the vehicle air purifier in this embodiment to achieve the corresponding functions is already available, and those skilled in the art only need to simply integrate and modify it according to the actual situation.
