Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted devices, in particular to an air intake device of a vehicle-mounted air conditioner. Background Art

[0002] The vehicle air conditioner is composed of a compressor, a condenser, a throttling element, an evaporator, a fan and necessary control components. It is an air conditioning system used to adjust the temperature and humidity in the vehicle and provide a comfortable environment for the passengers. When the compressor is working, the compressor inhales the low-temperature and low-pressure gaseous refrigerant from the evaporator. After compression, the temperature and pressure of the refrigerant increase and are sent to the condenser. In the condenser, the high-temperature and high-pressure gaseous refrigerant transfers heat to the air outside the vehicle passing through the condenser and liquefies into liquid. When the liquid refrigerant flows through the throttling device, the temperature and pressure decrease and enter the evaporator. In the evaporator, the low-temperature and low-pressure liquid refrigerant absorbs the heat of the air inside the vehicle passing through the evaporator and evaporates into gas. The gas is sucked into the compressor for the next cycle. In this way, through the circulation of the refrigerant in the system, the heat of the air inside the vehicle is continuously absorbed and discharged into the air outside the vehicle, so that the temperature of the air inside the vehicle gradually decreases. The internal circulation can improve the air conditioning effect, which is equivalent to re-cooling the cold air in the room. Of course, the air conditioning effect is better. However, long-term use of the internal circulation will reduce the air quality in the car, which may make people feel dizzy. You should use the external circulation for a few minutes after turning on the internal circulation for a while, so that fresh air can enter the car and improve the air quality. If the air conditioner's internal and external circulation switch is a mechanical lever instead of a button, you can put the lever in the middle of the internal and external circulation to allow an appropriate amount of air outside the car to enter, which can improve both the air quality and the air conditioning effect. In addition, when using the air conditioner to defrost and defog, it is effective to use the external circulation.

[0003] The application number is CN202120277994.7, which discloses an electric truck air conditioning device with an air purification function, and relates to the field of vehicle air conditioning technology, specifically an electric truck air conditioning device with an air purification function, including a vehicle exhaust box, the front of which is movably connected to a wind deflector, and the rear of which is fixedly connected to an air conditioning pipe. Through the coordinated arrangement of the vehicle exhaust box and the vehicle air conditioning purifier, the electric truck air conditioning device with an air purification function has the effect of integrating the purifier at the air outlet of the vehicle air conditioning to purify the blown air conditioning air again and thus improve the air quality in the cockpit. Through the coordinated arrangement of the electric valve and the vehicle air conditioning purifier, the electric truck air conditioning device with an air purification function has the effect of purifying the air inside the cockpit even if the air conditioning is not turned on, and the purifier is built into the vehicle exhaust box and does not occupy the cockpit space.

[0004] Although the above-mentioned utility model, through the coordinated arrangement of the vehicle-mounted exhaust box and the vehicle-mounted air-conditioning purifier, enables the electric truck air-conditioning device with air purification function to integrate the purifier at the air outlet of the vehicle-mounted air-conditioning to purify the blown air-conditioned air again and thus improve the air quality in the cockpit, and through the coordinated arrangement of the electric valve and the vehicle-mounted air-conditioning purifier, enables the electric truck air-conditioning device with air purification function to purify the air inside the cockpit even if the air-conditioning is not turned on and the purifier is built into the vehicle-mounted exhaust box and does not occupy the cockpit space, but there is a disadvantage that when the device is in use, the air entering it has not yet been filtered, which will cause the subsequent purification efficiency to be reduced.

[0005] Therefore, it is necessary to install a convenient filter component on the device, so that a certain convenient filtering connection method can be provided when the device is used. This can not only provide the effect of filtering and purifying the air, but also make the installation more convenient and the disassembly is also convenient. Utility Model Content
