DETAILED DESCRIPTION

[0027] like Figures 1 to 8 As shown, the present invention discloses a new energy vehicle air conditioning filter structure, including an air inlet cylinder 1, a sliding ring 2 slidably arranged at the front end of the air inlet cylinder 1, a filter screen 3 flatly installed on the sliding ring 2, and a fixed ring 4 fixedly arranged at the rear end of the air inlet cylinder 1. The front end of the air inlet cylinder 1 forms an air inlet of the air conditioner, which is used to inhale the air in the car. The front end mentioned here is the end close to the inside of the car. The sliding ring 2 is in a circular ring shape, and its outer side is in sliding and sealing cooperation with the inner wall of the air inlet cylinder 1. The filter screen 3 occupies the entire internal space of the sliding ring 2, and is made of hard stainless steel material. The fixed ring 4 is mainly used to limit the sliding position of the sliding ring 2, which is convenient for the subsequent disassembly and maintenance of the sliding ring 2.

[0028] Furthermore, the front end of the air inlet duct 1 disclosed in the present invention forms a straight pipe section that slides with the sliding ring 2, thereby facilitating the cooperation with the sliding ring 2. Of course, the rear end shape of the air inlet duct 1 can be selected as needed, which should be understandable to those skilled in the art.

[0029] Among them, a rotating dust removal structure is installed on the inner side of the filter screen 3 of the present invention, and an elastic recovery device 5 and a trigger device are provided between the sliding ring 2 and the fixed ring 4. The trigger device is used to start the rotating dust removal structure to remove dust after the sliding ring 2 is displaced toward the fixed ring 4, and the elastic recovery device 5 is used to drive the sliding ring 2 to return to its original position after relative displacement occurs between the sliding ring 2 and the fixed ring 4. In some other embodiments, the trigger device is electrically controlled, and receives a signal through a pressure sensor or a displacement sensor, and the signal is transmitted to a controller, thereby controlling the rotating dust removal structure to act.

[0030] Specifically, the rotary dust removal structure includes a central rotary support 6, three scrapers 7 evenly spaced along the circumference of the central rotary support 6 and installed on the outside of the central rotary support 6, a rotary drive device driving the central rotary support 6 to rotate, and a dust collection assembly installed on the air inlet cylinder 1 and corresponding to the scraper 7. The central rotary support 6 is coaxially installed at the center of the air inlet cylinder 1, and the scraper 7 is in a straight plate shape, and the scraper 7 contacts the inner side of the filter 3. During use of the device of the present invention, the rotary drive device can drive the central rotary support 6 and the scraper 7 to rotate, and under the scraping action of the scraper 7, impurities or dust on the surface of the filter 3 can be lifted, reducing the adhesion of impurities to the filter 3, and then sucked out under the action of the dust collection assembly, playing a role of regular cleaning.

[0031] In this embodiment, the central rotating support 6 includes a central tube 8, three scraper supports 9 evenly spaced along the circumference of the central rotating support 6 and installed on the outside of the central tube 8, the scraper supports 9 are used to install the scrapers 7, and the scrapers 7 are connected to the scraper supports 9 one by one. A guide rod 10 is fixed to the center of the filter 3, and the guide rod 10 is in sliding and sealing cooperation with the outer end of the central tube 8. When the filter 3 is displaced along the axial direction, it can be guided by the guide rod 10 to reduce the situation that the sliding ring 2 is stuck in the air inlet tube 1 due to deflection, and the stability of the device can be improved. It can be understood by those skilled in the art that the cross-sectional area of ​​the scraper support 9 is small to reduce wind resistance as much as possible.

[0032] In this embodiment, a main channel 11 extending along the length direction of the scraper 7 is provided on the inner side of the scraper 7, and the main channel 11 is close to the lower end of the scraper 7. A plurality of dust suction holes 12 connected to the main channel 11 are provided on the surface of the scraper 7 at the same time. The dust suction holes 12 are connected to the central tube 8 through a telescopic pipe, and the dust suction assembly includes a negative pressure pipe 13 connected to the inner end of the central tube 8. The negative pressure pipe 13 can be connected to a negative pressure fan to provide negative pressure to the dust suction holes 12, thereby adsorbing the dust on the filter 3. There are multiple groups of dust suction holes 12 evenly spaced, which can improve the dust adsorption capacity. The adsorption capacity is strong enough to prevent dust from entering the subsequent air-conditioning system. Of course, the filter 3 disclosed in the present invention only has the effect of preliminary filtering, and other multiple groups of filtering structures similar to filter elements can also be set at the rear end of the device.

[0033] In this embodiment, the telescopic pipe includes a straight outer pipe 14, an L-shaped inner pipe 15 and an L-shaped outer pipe 16, one end of the straight outer pipe 14 is connected to the central pipe 8, the other end of the straight outer pipe 14 is slidably sealed with one end of the L-shaped inner pipe 15, the other end of the L-shaped inner pipe 15 is slidably sealed with the upper end of the L-shaped outer pipe 16, the lower end of the L-shaped outer pipe 16 is connected to the main channel 11, and a support 17 for supporting the L-shaped inner pipe 15 is installed on the scraper 7. The telescopic pipe can adapt to the change of the position of the scraper 7, thereby providing a stable negative pressure adsorption capacity.

[0034] In this embodiment, an upper guide hole 18 is provided on the upper side of the scraper 7, the direction of the axis of the upper guide hole 18 is parallel to the axis of the air inlet tube 1, an upper guide rod 19 is slidably provided in the upper guide hole 18, an upper slider 20 is fixedly connected to the upper guide rod 19, an upper spring 21 is connected between the upper slider 20 and the scraper 7, an inner guide hole 22 is provided on the inner side of the scraper 7, an inner guide rod 23 is slidably provided in the inner guide hole 22, an inner slider 24 is fixedly connected to the inner guide rod 23, and an inner spring 25 is connected between the inner slider 24 and the scraper 7; an opening groove 26 cooperating with the scraper 7 is provided on the scraper support 9, and an upper slide groove 27 and an inner slide groove 28 cooperating with the upper slider 20 and the inner slider 24 are provided on the scraper support 9 at the same time. By setting the above structure for guidance, the scraper 7 can be stably displaced in both radial and axial directions, reducing the possibility of interference with the filter 3. When the scraper 7 rotates, centrifugal force can act on the scraper 7, so that the scraper 7 can move along the radial direction, thereby changing the scraping position and making the dust treatment more comprehensive.

[0035] As a further improvement of the embodiment of the present invention, a soft pad is fixed on the lower side of the scraper 7, and the soft pad is in contact with the filter 3 to reduce the loss of the filter 3. The soft pad and the filter 3 can also be in close contact, so that cleaning is convenient. A brush is provided on the soft pad, which can clean the dust on the filter 3 in all directions. The soft pad and the scraper 7 can be connected in a detachable manner, so that the soft pad can be maintained in time.

[0036] In this embodiment, the rotation drive device includes a support rod 29, a rotating ring 30, a limit seat 31, a gear 32 and a motor 33. The central rotating support 6 is fixedly connected to the rotating ring 30 through the support rod 29. The rotating ring 30 is rotatably matched with the limit seat 31. The limit seat 31 is fixed to the inner wall of the air inlet cylinder 1. The outer side of the rotating ring 30 is meshed with the gear 32, and the gear 32 is connected to the output end of the motor 33. The limit seat 31 can limit the rotating ring 30 to increase the stability of the structure when rotating. By adopting the motor 33 to control the rotation, the control is more convenient.

[0037] In this embodiment, the trigger device includes a lever 34, a switch support 35 and a reset torsion spring 36. The middle part of the switch of the motor 33 is hinged to the switch support 35 and a reset torsion spring 36 is connected between the two. One end of the lever 34 is hinged to the sliding ring 2, and the other end of the lever 34 is hinged to the switch of the motor 33. The triggering is performed in a purely mechanical manner, and the triggering process is more stable.

[0038] In this embodiment, a ring groove 37 is provided on the surface of the rotating ring 30, and an arc groove 38 corresponding to the ring groove 37 is provided on the surface of the limit seat 31. A ball 39 is installed in the space formed by the ring groove 37 and the arc groove 38, which can reduce the friction between the rotating ring 30 and the limit seat 31, making the device smoother during use.

[0039] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
