Description

Technical Field

[0001] This utility model relates to the field of automotive interior systems, and specifically to a cabin air purification system with a blower positioned on the side. Background Technology

[0002] Carbon dioxide and water vapor contained in the breath of drivers and passengers can accumulate in the passenger compartment. Too high a concentration of carbon dioxide can significantly reduce the driver's ability to concentrate, and too high a humidity can cause the vehicle's windows (such as the windshield or side windows) to fog up. These factors can all pose unpredictable dangers to the vehicle's occupants.

[0003] Therefore, an air purifier is needed to control cabin humidity to ensure occupant safety. In existing air purifiers, the blower is typically placed directly below the filter for low flow resistance and high uniformity. However, because the blower and filter are stacked together, the overall size of the product is too tall, making it difficult to fit into the flat spaces of many car models, such as under the seats. Therefore, there is an urgent need for a flat, air-purifying device with superior flow resistance and uniformity to adapt to the spaces of more car models. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide a cabin air purification system with a blower positioned on the side.

[0005] Based on the above objectives, this application provides the following technical solution:

[0006] One of the technical solutions of this application provides a cabin air purification system with a blower positioned on the side, comprising the following structure:

[0007] Air inlet housing, heater, adsorption unit, lower housing, blower, air outlet housing, damper mechanism;

[0008] The air inlet housing, lower housing, and air outlet housing together constitute the housing structure of the cabin air purification system with the blower on the side;

[0009] The adsorption unit is detachably installed and fixed between the air inlet housing and the lower housing. After installation, it can achieve the sealing between the blower-side cabin air purification system and the outside world, as well as the separation of the humid side and the dry side of the blower-side cabin air purification system. The humid side is the side that is not adsorbed by the adsorption unit, and the dry side is the opposite. The detachable method is any one of the following: threaded screw connection, snap-fit ​​connection, and plug-in connection.

[0010] The air inlet housing is designed with a system air inlet and a heater mounting structure; the heater is inserted into the heater mounting structure from the outside and then fixedly connected to the heater mounting structure by a threaded screw structure; the heater is located near the system air inlet.

[0011] The blower is detachably fixed to the air outlet housing and is located in the cavity formed between the lower housing and the air outlet housing.

[0012] Furthermore, the system's air inlet is connected to the cockpit.

[0013] Furthermore, the system is equipped with an air filter grille at the air inlet, which can effectively block dust, debris and other contaminants from entering the system, protect the heater and adsorption unit from damage, and extend their service life.

[0014] Furthermore, a system air outlet is integrated at the outlet of the lower housing and the air outlet housing; a system drain outlet is designed on the lower housing near the system air outlet; the system air outlet is connected to the cabin, and the system drain outlet is connected to the outside of the cabin.

[0015] Furthermore, the air outlet housing is designed with a damper mechanism mounting structure; the damper mechanism is mounted on the air outlet housing near the system air outlet via the damper mechanism mounting structure.

[0016] Furthermore, the air outlet housing and the lower housing are respectively designed with mutually cooperating air outlet housing mounting structures; the lower housing is connected to the air outlet housing through the air outlet housing mounting structures.

[0017] Furthermore, the damper mechanism consists of a drive motor, a coupling, and an air outlet flap; the damper mechanism controls the opening and closing of the system air outlet and the system drain outlet through the air outlet flap; the drive motor is connected to the vehicle control system, the control system is electrically connected to the control circuit of the drive motor, and the output shaft of the drive motor is connected to the rotating shaft of the air outlet flap through the coupling to realize transmission; the function of the air outlet flap is to block the system air outlet or the system drain outlet.

[0018] Furthermore, the heater is preferably a PTC heater, which uses a positive temperature coefficient thermistor material and has advantages such as automatic temperature control, rapid heating, and safety and reliability. Its heating power can be adjusted according to the ambient temperature and system requirements to ensure that it can provide suitable heating effects under different operating conditions.

[0019] Furthermore, the blower is preferably a centrifugal blower. Centrifugal blowers have the characteristics of high air pressure, stable air volume, and low noise, ensuring stability and reliability during high-speed rotation.

[0020] Furthermore, the outer sides of the air inlet housing, the lower housing, and the air outlet housing are all provided with several staggered reinforcing ribs.

[0021] Furthermore, the humidity control system of the blower-side-mounted cabin air purification system has two modes:

[0022] Adsorption Mode (M1): When the temperature and humidity reach the preset values, the blower is turned on, and the system will enter adsorption mode (M1) from standby mode (M0). At this time, the blower will draw air from the cabin through the system air inlet. When the air is drawn in, water molecules and carbon dioxide molecules in the air are absorbed as it passes through the adsorption unit. At the same time, the damper mechanism will open the air outlet and close the drain outlet. The purified air will return to the cabin through the air outlet. The system completes one purification cycle. Through multiple purification cycles, the system achieves the purpose of purifying the entire cabin and ensures that the driver and passengers will not experience fatigue and drowsiness due to excessively high concentrations of carbon dioxide. This reduces the number of times the vehicle's air conditioning defrost is turned on, thereby reducing the energy consumption of the air conditioning system and greatly improving the vehicle's driving range.

[0023] Regeneration Mode (M2): When the water absorption in the adsorption unit is close to saturation, desorption of adsorption unit 3 is required. The system switches from adsorption mode (M1) to regeneration mode (M2). At this time, the heater is activated, and the damper mechanism is switched to close the air outlet and open the drain outlet. The blower will draw air from the cabin through the system air inlet. The air becomes high-temperature air after passing through the heater. When the hot air blows through the adsorption unit, it will carry away the water molecules and carbon dioxide molecules. The high-temperature, high-humidity, and high-carbon dioxide concentration air will be discharged outside the cabin through the drain outlet. The system completes one desorption cycle. After several desorption cycles, the adsorption unit can be reused.

[0024] Compared with the prior art, the present invention has at least the following improvements and beneficial effects:

[0025] (1) Flat design: Compared with traditional air purifiers that place the blower below the filter, this invention places the blower on the side of the filter, reducing the overall height and making the product flatter and easier to fit into more vehicle spaces.

[0026] (2) Lower flow resistance: The present invention has lower flow resistance compared to the blower arrangement of traditional air purifiers.

[0027] (3) Higher uniformity: The arrangement of the blower in this invention has higher uniformity compared to that of traditional air purifiers. Attached Figure Description

[0041] Example 1: A cabin air purification system with a blower positioned on the side

[0042] Combination Figures 1 to 7 The cabin air purification system with a side-mounted blower provided in this embodiment includes the following structural features:

[0043] The shell structure is composed of an inlet shell 1, a lower shell 4, and an outlet shell 6, assembled to form a sealed cavity. Each shell has staggered reinforcing ribs on its outer side to enhance structural strength. The inlet shell 1 has a system air inlet 11, and its inner wall is equipped with an air filter grille to block dust and debris. A heater mounting structure 12 is designed on the outer side of the inlet shell 1, where a PTC heater 2 is fixedly mounted using threaded screws. The lower shell 4 and the outlet shell 6 are connected via an outlet shell mounting structure 16, and the outlet formed by their integration is a system air outlet 13. A system drain outlet 14 is located on the lower shell 4 near the system air outlet 13.

[0044] The adsorption unit 3 is detachably installed between the air inlet housing 1 and the lower housing 4, dividing the cavity into a humid side and a dry side; the humid side is the side where the air has not been adsorbed, and the dry side is the side where the air flows after adsorption and purification. The centrifugal blower 5 is detachably fixed on the air outlet housing 6 and is located in the cavity formed by the lower housing 4 and the air outlet housing 6, and is used to drive the air flow.

[0045] The damper mechanism 7 is installed within the damper mechanism mounting structure 15 on the air outlet housing 6, and includes a drive motor 8, a coupling 9, and an air outlet flap 10. The coupling 9 connects the drive motor 8 to the rotating shaft of the air outlet flap 10, and the rotation of the air outlet flap 10 achieves two state switching: State 1: The flap opens the system air outlet 13 and closes the system drain outlet 14, allowing air to return to the cabin. State 2: The flap closes the system air outlet 13 and opens the system drain outlet 14, expelling high-humidity air from the cabin.

[0046] Functional connection and airflow direction: The system air inlet 11 is connected to the cabin. Air is heated by the heater 2 and enters the humid side inside the shell. The dry air purified by the adsorption unit 3 is driven to the dry side by the blower 5 and discharged through the system air outlet 13 or drain outlet 14. The PTC heater 2 is linked with the centrifugal blower 5 and, in conjunction with the flap switching of the damper mechanism 7, realizes dual-mode operation of adsorption and regeneration.

[0047] In summary, this embodiment ensures cavity sealing and strict isolation between the wet and dry sides through a combination design of detachable mounting structures. The damper mechanism is integrated with the housing structure, and the flap movement is controlled by a single drive motor, simplifying system complexity. The reinforcing rib layout enhances the housing's resistance to deformation and adapts to vehicle vibration environments.

[0048] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
