[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figure 1 and Figure 2, an embodiment provided by the utility model: a new type of automotive air-conditioning cold air distribution valve, which includes a housing 1. In the middle of the top wall of the housing 1, a hydraulic rod 3 is fixedly connected. One end of the hydraulic rod 3 is fixedly connected with a displacement ring 4. On the front and rear sides of the displacement ring 4, fixing blocks 5 are fixedly connected. A bolt 6 is threadedly inserted through the right side of the fixing block 5. The left end of the bolt 6 is threadedly connected with a cleaning shell 7. On the inner bottom wall of the cleaning shell 7, a plurality of reset springs 8 are fixedly connected at equal intervals. The top ends of the plurality of reset springs 8 are all fixedly connected with a cleaning sponge 9. On the left ends of the upper and lower sides of the housing 1, one-way valves 11 are communicated; on the left and right sides of the housing 1, flanges 12 are fixedly connected. Inside the flanges 12, a plurality of preset grooves are opened at equal intervals;

[0031] Specifically, when the hydraulic rod 3 is started, one end of it will start to reciprocate. This movement causes the displacement ring 4 to move accordingly. A firm connection is formed between the displacement ring 4 and the cleaning shell 7 through the bolt 6. Therefore, when the displacement ring 4 moves, the cleaning shell 7 will also move synchronously. Inside the cleaning shell 7, the springs 8 are fixed with the cleaning sponge 9. The elastic force design of these springs 8 enables the cleaning sponge 9 to closely fit the outer shell 1 of the valve. The cleaning sponge 9 can ensure full contact and clean without dead angles. During the cleaning process, the cleaning sponge 9 will repeatedly wipe the outer shell 1 of the valve as the displacement ring 4 moves, effectively removing the water droplets and dirt on the surface. The flanges 12 make it convenient to install and fix the valve.

[0032] Refer to Figure 1 and Figure 3 , on the right side of the top wall of the housing 1, an adjusting mechanism 2 is provided. The adjusting mechanism 2 is used to adjust the cold air flow passing effect of the valve. The adjusting mechanism 2 includes a protective shell 201. The bottom wall of the protective shell 201 is fixedly connected to the top wall of the housing 1. On the inner top wall of the protective shell 201, a servo motor 202 is fixedly connected. The output end of the servo motor 202 is fixedly connected with a rotating column 203. On the outer wall of the rotating column 203, an adjusting plate 204 is fixedly connected. On the front and rear sides of the adjusting plate 204, arc-shaped shells 205 are fixedly connected;

[0033] Specifically, when the servo motor 202 works, it will drive the adjusting plate 204 to rotate synchronously. There is a certain gap between the edge of the adjusting plate 204 and the inner wall of the housing 1. By changing the rotation angle of the adjusting plate 204, the size of the gap can be adjusted, thereby controlling the channel area through which the cold air flows, and further achieving the purpose of controlling the flow rate. The arc-shaped shell 205 rotates synchronously with the adjusting plate 204 to form a gradually shrinking channel. The cold air enters from the end with a larger diameter. When passing through the end with a smaller diameter, due to the reduction of the channel, the flow rate will increase significantly, which can effectively increase the flow rate of the cold air and enhance the refrigeration effect.

[0034] Refer to Figure 1 , Figure 2 and Figure 3, sealing plates 206 are fixedly connected to both the upper and lower ends of the outer wall of the rotating column 203, sealing grooves 207 are respectively formed in the upper and lower sides of the inner wall of the outer shell 1, and the outer walls of the two sealing plates 206 are respectively rotatably connected to the corresponding sealing grooves 207; a control switch 14 is fixedly connected to the front side of the outer shell 1, and the control switch 14 is electrically connected to the hydraulic rod 3 and the servo motor 202 respectively; a waterproof cover 15 is arranged on the left side of the control switch 14, and the rear side of the waterproof cover 15 is rotatably connected to the front side of the outer shell 1 through a hinge;

[0035] Specifically, since the outer walls of the two sealing plates 206 are respectively rotatably connected to the corresponding sealing grooves 207, the sealing effect during the rotation of the rotating column 203 is improved. Through the control switch 14 which is electrically connected to the hydraulic rod 3 and the servo motor 202 respectively, the control switch 14 can complete the opening and closing of the device. Through the waterproof cover 15, the control switch 14 can be protected from water. The model of the hydraulic rod 3 used in the present utility model is hydraulic rod GYCD - 110 / 750, and the model of the control switch 14 is control switch lw2.

[0036] Refer to Figure 2 , rubber pads 10 are fixedly connected to the middle parts of the two bolts 6, and the outer shapes of the two rubber pads 10 are both designed in a ring shape; filter discs 13 are fixedly connected to the middle parts of the left and right sides of the outer shell 1, and the external dimensions of the two filter discs 13 match the internal dimensions of the outer shell 1;

[0037] Specifically, through the rubber pads 10, the damage caused by the rotation of the fixing block 5 by the bolts 6 is reduced. Through the filter discs 13, the particulate matter contained in the cold air is effectively reduced.

[0038] Working principle: When starting to clean, by starting the hydraulic rod 3, the displacement ring 4 is driven by one end of the hydraulic rod 3, and then reciprocates along with one end of it, so that the cleaning shell 7 fixedly installed by the bolts 6 also moves accordingly. Thus, the cleaning sponge 9 fixed by the spring 8 inside the cleaning shell 7 completes the cleaning of the valve outer shell 1. Through the elastic force of the multiple springs 8, the cleaning sponge 9 can closely adhere to the outer shell of the valve, improving the cleaning effect and reducing the situation that water droplets are likely to combine with dirt over a long time and then corrode the valve outer shell 1;

[0039] And through the drive of the servo motor 202, the rotating column 203 drives the adjusting plate 204 to rotate, so as to achieve the effect of controlling the flow through by adjusting the gap between the rotation angle of the adjusting plate 204 and the inner wall of the outer shell 1, thereby completing the purpose of controlling the cold air delivery and distribution. At the same time, when the arc-shaped shell 205 rotates following the adjusting plate 204, when the cold air passes from a larger diameter to a smaller diameter, the flow rate is increased due to the decrease in diameter, thereby improving the refrigeration effect.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
