A first ventilation grille and a second ventilation grille are provided on both sides of the protective cover plate respectively. An air inlet shell is provided at the opening of the main air inlet, and the air inlet shell is connected to the protective plate, the first ventilation grille and the second ventilation grille.

[0006] The air inlet adjustment structure includes a first air inlet damper and a second air inlet damper, both of which are connected to the fixed shell rotating shaft, a baffle is provided in the middle of the total air inlet, one side of the baffle forms the first air inlet, and the other side of the baffle forms the second air inlet, the first air inlet damper shields the first air inlet, and the second air inlet damper shields the second air inlet, and the first air inlet damper and the second air inlet damper are connected to an adjustment unit.

[0007] The adjustment unit includes a first lever, a second lever and a dial, the first lever is connected to one end of the first air inlet damper, the second lever is connected to the second air inlet damper, a track groove structure is provided on the dial, and the first lever and the second lever are located in the track groove structure.

[0008] The track groove structure includes a first track groove and a second track groove. One end of the first shift rod is connected to a first connecting rod, and one end of the first connecting rod is embedded in the first track groove. One end of the second shift rod is connected to a second connecting rod, and one end of the second connecting rod is embedded in the second track groove.

[0009] The dial includes a rotating column, a rotating ring is sleeved on the rotating column, a connecting plate is provided between the rotating ring and the rotating column, a first arc plate and a second arc plate are connected to the rotating ring, the first track groove is opened on the first arc plate, and the second track groove is opened on the second arc plate.

[0010] The first air inlet damper includes a first air shield plate, and both ends of the first air shield plate are connected to first fan-shaped plates. The second air inlet damper includes a second air shield plate, and both ends of the second air shield plate are connected to second fan-shaped plates.

[0011] The first wind shield is provided with a first air guide groove at a distance from the back thereof, and the second wind shield is provided with a second air guide groove at a distance from the back thereof.

[0012] Limiting plates are provided at both ends of the protective sleeve, and the limiting plates abut against the air filter element.

[0013] A method for using an air intake mechanism of an automobile air conditioner, specifically comprising:

[0014] In full external circulation mode, turn the dial to adjust the first air inlet damper to cover the first ventilation grille, and adjust the second air inlet damper to cover the second ventilation grille, and air enters through the first air inlet and the second air inlet;

[0015] In the first half-internal circulation and half-external circulation mode, turn the dial to adjust the first air inlet damper to cover the first ventilation grille, and adjust the second air inlet damper to cover the second air inlet. Air enters from the first air inlet and the second ventilation grille.

[0016] In the second half-internal circulation and half-external circulation mode, turn the dial to adjust the first air inlet damper to cover the first air inlet, and adjust the second air inlet damper to cover the second ventilation grille, and air enters from the second air inlet and the first ventilation grille;

[0017] Full internal circulation mode; adjust the first air inlet damper to cover the first air inlet, adjust the second air inlet damper to cover the second air inlet, and the air enters through the first ventilation grille and the second ventilation grille.

[0018] The technical effect of the present invention is: by turning the dial, the direction of the first air inlet damper and the second air inlet damper is adjusted to realize the switching of four modes: full external circulation mode, first half internal circulation and half external circulation mode, second half internal circulation and half external circulation mode, and full internal circulation.

[0019] In full external recirculation mode, turning the dial activates the adjustment unit, causing the first air intake flap to cover the first vent grille, and the second air intake flap to cover the second vent grille, completely blocking the air circulation path inside the vehicle. Air is forced to enter only through the first and second air inlets, ensuring that all incoming air comes from the outside environment. When the outside air is fresh, full external recirculation mode can quickly introduce a large amount of fresh air to refresh the air inside the vehicle.

[0020] In the first half-internal circulation, half-external circulation mode, the air intake path is split in two: one portion is introduced through the first air inlet, while the other portion is circulated through the second ventilation grille, achieving a mixed intake of air from both inside and outside. When the outside air is somewhat polluted, this mode allows for the introduction of an appropriate amount of fresh air while reducing the amount of polluted air entering, while also utilizing the purified air inside the vehicle for recirculation.

[0021] In the second half-internal circulation and half-external circulation mode, air is introduced from outside the car through the second air inlet, and the air inside the car is circulated from the first ventilation grille, which also achieves the mixing of air inside and outside the car. It can not only avoid excessive dirty air, but also ensure the fluidity of the air inside the car, effectively improve the air quality inside the car, and at the same time reasonably distribute the air intake path to optimize the operating efficiency of the air-conditioning system.

[0022] In full internal recirculation mode, air circulates exclusively through the first and second louvers, preventing it from exchanging air with the outside air. When the external environment is harsh, such as during severe smog or dust storms, or when passing through areas with strong odors, such as those near waste treatment plants or chemical plants, full internal recirculation effectively blocks polluted air and odors from entering the vehicle, maintaining clean air inside.

DETAILED DESCRIPTION

[0028] The following is a further detailed description of the specific implementation methods of the present invention through the description of the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0029] like Figures 1 to 3 As shown, an air intake mechanism for an automobile air conditioner includes a fixed housing 1, an air filter element 2 disposed within the fixed housing 1, a main air inlet 3 disposed at one end of the fixed housing 1, and an air intake adjustment structure 4 disposed at one end of the main air inlet 3. The fixed housing 1 serves as the main frame of the air conditioner air intake mechanism, and houses the air filter element 2. The main air inlet 3 is defined at one end of the fixed housing 1, and the air intake adjustment structure 4 is disposed at one end of the main air inlet 3. Air first enters through the main air inlet 3, and is then regulated by a first air intake damper 41 and a second air intake damper 42 through the air intake adjustment structure 4. The first and second air intake dampers 41, 42 are used to select whether to block or not block the air entering from the main air inlet 3, thereby selecting the air intake circulation mode for the air conditioner.

[0030] The air inlet adjustment structure 4 includes a first air inlet damper 41 and a second air inlet damper 42, both of which are connected to the rotating shaft of the fixed housing 1. A baffle 401 is provided in the middle of the main air inlet 3. One side of the baffle 401 forms the first air inlet 301, and the other side of the baffle 401 forms the second air inlet 302. The first air inlet damper 41 blocks the first air inlet 301, and the second air inlet damper 42 blocks the second air inlet 302. The first air inlet damper 41 and the second air inlet damper 42 are connected to an adjustment unit 43. The first air inlet damper 41 and the second air inlet damper 42 are both connected to the fixed housing 1 via a rotating shaft, and the first air inlet damper 41 and the second air inlet damper 42 can rotate around the shaft. A baffle 401 is provided in the middle of the main air inlet 3, dividing the main air inlet 3 into a first air inlet 301 and a second air inlet 302. The main air inlet 3 can be more conveniently blocked by the first air inlet damper 41 and the second air inlet damper 42. The first air inlet damper 41 can be rotated to block the first air inlet 301, and the second air inlet damper 42 can be rotated to block the second air inlet 302. This allows you to change the way air enters and select the air circulation mode of the air conditioner.

[0031] The fixed housing 1 includes a protective cover 101, which is mounted on the air filter element 2. Protective plates 102 are provided at both ends of the protective cover 101. A first ventilation grille 103 and a second ventilation grille 104 are provided on either side of the protective cover 101. An air inlet housing 6 is provided at the opening of the main air inlet 3. The air inlet housing 6 is connected to the protective plates 102, the first ventilation grille 103, and the second ventilation grille 104. The protective cover 101 is mounted on the air filter element 2. Protective plates 102 are provided at both ends of the protective cover 101. A first ventilation grille 103 and a second ventilation grille 104 are provided on either side of the protective cover 101. The protective cover 101, the protective plate 102, the first ventilation grille 103, and the second ventilation grille 104 form a cavity, and the first air inlet damper 41 and the second air inlet damper 42 are located in the cavity. The air inlet housing 6 is provided at the opening of the main air inlet 3. The air inlet housing 6 is connected to the protective plate 102, the first ventilation grille 103, and the second ventilation grille 104, to form a complete fixed and air circulation structure. By rotating the first air inlet damper 41, the first ventilation grille 103 can be blocked. After the first air inlet damper 41 blocks the first ventilation grille 103, air enters through the first air inlet 301. After rotating the first air inlet damper 41 blocks the first air inlet, air enters through the first ventilation grille 103. By rotating the second air inlet damper 42, the second ventilation grille 104 can be blocked, and air enters through the second air inlet 302. By rotating the second air inlet damper 42, the second air inlet 302 can be blocked, and air enters through the second ventilation grille 104.

[0032] The adjustment unit 43 includes a first lever 431, a second lever 432, and a dial 5. The first lever 431 is connected to one end of the first air inlet damper 41, and the second lever 432 is connected to the second air inlet damper 42. The dial 5 is provided with a track groove structure 51, and the first and second levers 431, 432 are located within the track groove structure 51. By rotating the dial 5, the track groove structure 51 is driven, and the first and second connecting rods 513, 514 within the track groove structure 51 follow the track groove structure 51, driving the first and second levers 431, 432 to move. The first lever 431 drives the first air inlet damper 41 to rotate about its axis, thereby controlling the first air inlet damper 41. The second lever 432 drives the second air inlet damper 42 to rotate about its axis, thereby controlling the second air inlet damper 42. By controlling the orientation of the first and second air inlet dampers 41, 42 by the adjustment unit 43, the air circulation mode of the air conditioner is changed. The effective area of air circulation inside and outside is increased, and the structure is simple, the floor space is small, and it can adapt to a variety of vehicle models.

[0033] By coordinating the first air inlet damper 41, the second air inlet damper 42, the first lever 431 and the second lever 432, the direction of the first air inlet damper 41 and the second air inlet damper 42 are changed to change the air conditioning air intake circulation mode.

[0034] The track groove structure 51 includes a first track groove 511 and a second track groove 512. One end of the first lever 431 is connected to a first connecting rod 513, which is embedded in the first track groove 511. One end of the second lever 432 is connected to a second connecting rod 514, which is embedded in the second track groove 512. When the dial 5 is rotated, the first and second track grooves 511, 512 rotate accordingly. When one end of the first track groove 511 abuts the first connecting rod 513, the first connecting rod 513 rotates along with the first track groove 511. The first connecting rod 513, in turn, drives the first lever 431 to rotate, thereby controlling the orientation of the first air inlet damper 41. When one end of the second track groove 512 abuts the second connecting rod 514, the second connecting rod 514 drives the second lever 432 to rotate, thereby controlling the orientation of the second air inlet damper 42.

[0035] The dial 5 includes a rotating column 501, a rotating ring 502 is sleeved on the rotating column 501, a connecting plate 503 is provided between the rotating ring 502 and the rotating column 501, a first curved plate 504 and a second curved plate 505 are connected to the rotating ring 502, a first track groove 511 is provided on the first curved plate 504, and a second track groove 512 is provided on the second curved plate 505. The rotating ring 502 and the rotating column 501 are the main bodies of the dial 5. The arrangement of the rotating ring 502 and the rotating column 501 facilitates rotation. The connecting plate 503 is arranged in a circularly symmetrical manner. One end of the connecting plate 503 is connected to the rotating column 501, and the other end of the connecting plate 503 is connected to the rotating ring 502. The connecting plate 503 connects the rotating ring 502 and the rotating column 501 together to enhance the overall structural strength of the dial 5. The first curved plate 504 is used to open a first track groove 511 to facilitate control of the first air inlet damper 41. The second curved plate 505 is used to open a second track groove 512 to facilitate control of the second air inlet damper 42.

[0036] The first air inlet damper 41 includes a first air shield 411 , with first fan-shaped plates 412 connected to both ends of the first air shield 411 . The second air inlet damper 42 includes a second air shield 421 , with second fan-shaped plates 422 connected to both ends of the second air shield 421 . The first wind shield 411 is the main body of the first air inlet damper 41, and the first wind shield 411 is an arc-shaped structure as a whole. The first wind shield 411 is used to block the first air inlet 301 or the first ventilation grille 103, changing the air entry position. The first fan plate 412 at one end of the first wind shield 411 is used to be connected to the rotating shaft of the fixed shell 1, and the first fan plate 412 at the other end of the first wind shield 411 is used to connect the first lever 431 to rotate, so that the first lever 431 can control the direction of the first air inlet damper 41; the second wind shield 421 is an arc-shaped structure as a whole, and the second wind shield 421 is used to block the second air inlet 302 or the second ventilation grille 104, changing the air entry position, the second fan plate 422 at one end of the second wind shield 421 is used to be connected to the rotating shaft of the fixed shell 1, and the second fan plate 422 at the other end of the second wind shield 421 is used to connect the second lever 432, so that the second lever 432 can control the direction of the second air inlet damper 42.

[0037] First air guide slots 413 are spaced apart on the back of the first windshield 411, and second air guide slots 423 are spaced apart on the back of the second windshield 421. When the first windshield 411 blocks the first air inlet 301 or the first ventilation grille 103, the first air guide slots 413 guide air flow, reducing wind resistance and allowing air to pass more smoothly. When the second windshield 421 blocks the second air inlet 302 or the second ventilation grille 104, the second air guide slots 423 guide air flow, reducing wind resistance and allowing air to pass more smoothly.

[0038] The protective cover 101 is provided with limit plates 7 at both ends, which abut against the air filter element 2. The limit plates 7 are provided at both ends of the protective cover 101 and abut against the air filter element 2. The limit plates 7 fix the air filter element 2 to prevent the air filter element 2 from moving, ensuring that air can be effectively filtered through the air filter element 2 and maintaining the normal operation of the air intake system.

[0039] A method for using an air intake mechanism of an automobile air conditioner, specifically comprising:

[0040] In full external circulation mode, rotating the dial 5 adjusts the first air inlet damper 41 to cover the first ventilation grille 103, and the second air inlet damper 42 to cover the second ventilation grille 104, allowing air to enter through the first air inlet 301 and the second air inlet 302. In full external circulation mode, rotating the dial 5 drives the adjustment unit 43 to operate, causing the first air inlet damper 41 to cover the first ventilation grille 103 and the second air inlet damper 42 to cover the second ventilation grille 104, completely blocking the air circulation path inside the vehicle and forcing air to enter only through the first air inlet 301 and the second air inlet 302, ensuring that the air introduced comes entirely from the outside environment. When the outside air is fresh, such as when driving in the suburbs or in the mountains, full external circulation mode can quickly introduce a large amount of fresh air, refreshing the air inside the vehicle and effectively reducing the carbon dioxide concentration inside the vehicle, preventing drowsiness caused by poor air circulation. It also promptly removes odors from the vehicle, maintaining a fresh air environment and creating a comfortable breathing environment for the driver and passengers.

[0041] In the first half-internal circulation, half-external circulation mode, dial 5 is rotated to adjust the first air inlet damper 41 to block the first vent grille 103, and the second air inlet damper 42 to block the second air inlet 302. Air then enters through the first air inlet 301 and the second air inlet 104. In this mode, the air intake path is split into two: one portion of the air is drawn in through the first air inlet 301 to draw in fresh air from outside, while the other portion of the air is circulated into the vehicle through the second vent grille 104, achieving a mixed intake of air from both inside and outside. When the outside air is somewhat polluted, such as in mild haze or road dust, this mode allows for the introduction of an appropriate amount of fresh air while reducing the amount of polluted air entering. Furthermore, it utilizes purified air within the vehicle for circulation, reducing the load on the air conditioning system while ensuring air freshness, thus saving energy and effectively reducing the entry of pollutants into the vehicle, maintaining relatively good air quality within the vehicle.

[0042] In the second half-internal circulation and half-external circulation mode, turn the dial 5 to adjust the first air inlet damper 41 to cover the first air inlet 301, and adjust the second air inlet damper 42 to cover the second ventilation grille 104, and the air enters through the second air inlet 302 and the first ventilation grille 103; in the second half-internal circulation and half-external circulation mode, the air outside the vehicle is introduced from the second air inlet 302, and the air inside the vehicle is circulated from the first ventilation grille 103, and the air inside and outside the vehicle is mixed. It can avoid excessive inhalation of dirty air and ensure the fluidity of the air inside the vehicle, effectively improve the air quality inside the vehicle, and at the same time reasonably distribute the air intake path to optimize the operating efficiency of the air-conditioning system.

[0043] Full internal circulation mode: adjust the first air inlet damper 41 to block the first air inlet 301, and adjust the second air inlet damper 42 to block the second air inlet 302, and air enters through the first ventilation grille 103 and the second ventilation grille 104. In the full internal circulation mode, air circulates in the vehicle only through the first ventilation grille 103 and the second ventilation grille 104, and is not exchanged with the outside air. When the external environment is harsh, such as encountering severe haze or sandstorms, or passing through areas with strong odors such as garbage disposal plants and chemical plants, the full internal circulation mode can effectively isolate the outside dirty air and odors from entering the vehicle, keeping the air inside the vehicle clean. In addition, when cooling rapidly in summer or heating rapidly in winter, turning on the full internal circulation mode can reduce the loss of hot and cold air, allowing the temperature inside the vehicle to reach the set value faster, improving the cooling and heating efficiency of the air conditioner, and reducing energy consumption.

[0044] Functions and Effects of the Embodiments

[0045] By rotating the dial 5, the directions of the first air inlet damper 41 and the second air inlet damper 42 are adjusted to realize switching among the four modes of full external circulation mode, the first half internal circulation and half external circulation mode, the second half internal circulation and half external circulation mode, and full internal circulation.

[0046] In full external circulation mode, rotating the dial 5 activates the adjustment unit 43, causing the first air inlet damper 41 to cover the first ventilation grille 103 and the second air inlet damper 42 to cover the second ventilation grille 104, completely blocking the air circulation path inside the vehicle and forcing air to enter only through the first air inlet 301 and the second air inlet 302, ensuring that all the air introduced comes from the outside environment. When the outside air is fresh, full external circulation mode can quickly introduce a large amount of fresh air to refresh the air inside the vehicle.

[0047] In the first half-internal circulation, half-external circulation mode, the air intake path is split in two: one portion is introduced through the first air inlet 301 to draw in fresh air from outside the vehicle, while the other portion is circulated into the vehicle through the second ventilation grille 104, achieving a mixed intake of air from both inside and outside the vehicle. When the outside air is somewhat polluted, this mode allows for the introduction of an appropriate amount of fresh air while reducing the amount of polluted air entering, while also utilizing the purified air already circulating within the vehicle.

[0048] In the second half-internal circulation and half-external circulation mode, air is introduced from the second air inlet 302 to the outside air, and the air inside the car is circulated from the first ventilation grille 103, so that the air inside and outside the car are mixed and enter. It can avoid excessive dirty air and ensure the fluidity of the air inside the car, effectively improve the air quality inside the car, and at the same time reasonably distribute the air intake path to optimize the operating efficiency of the air-conditioning system.

[0049] In full internal recirculation mode, air circulates exclusively within the vehicle through the first and second ventilator grilles 103 and 104, without exchanging air with the outside air. When the external environment is harsh, such as during severe smog or dust storms, or when passing through areas with strong odors, such as those near waste treatment plants or chemical plants, full internal recirculation effectively prevents polluted air and odors from entering the vehicle, maintaining clean air inside.
