[0016] Please refer to Figure 1The utility model relates to a kind of pneumatic car interior cleaning tools, including rotating speed regulating valve 1, suction force regulating valve 2, pneumatic motor 3, cleaning brush 4, dust storage box 5, pipeline 6 and dust suction pipe 7, the inlet end of the pipeline 6 is equipped with three-way valve 8, three-way valve 8 divides into two branches with pipeline 6, one branch is connected with pneumatic motor 3 by rotating speed regulating valve 1, another branch is connected with dust storage box 5 by suction force regulating valve 2, suction port 61 is opened on the pipeline between suction force regulating valve 2 and dust storage box 5, the lateral wall of the pneumatic motor 3 is opened symmetrically through hole 31, through hole 31 is fixedly connected dust suction pipe 7, and the side end of dust suction pipe 7 corresponding suction force regulating valve 2 is connected with suction port 61;

[0017] The rotor shaft 32 of the pneumatic motor 3 is hollow shaft, and the two side ends of the rotor shaft 32 extend outward along the dust suction pipe 7 by penetrating through the through hole 31, one end of which extends to the suction port 61, and the diameter of this end is smaller than the diameter of the other end, which is a necked portion 321, and the other end of the rotor shaft 32 is threadedly connected with the brush head of the cleaning brush 4.

[0018] The cleaning brush 4 is composed of a brush head 41 and bristles 42, and the brush head 41 is a hollow structure. A plurality of dust suction holes 411 are arranged at the periphery of the bristles 42 on the surface of the brush head 41. The brush head 41 is threadedly connected with the rotor shaft 32 at the end away from the bristles 42.

[0020] Working principle:

[0021] In specific application, high-pressure gas enters the pipeline 6 through the three-way valve 8. Part of the high-pressure gas in the pipeline drives the pneumatic motor 3 to rotate through the rotating speed regulating valve 1, so that the rotor shaft of the pneumatic motor 3 drives the cleaning brush 4 to rotate. At this time, the dust and other impurities on the surface of the car interior are brushed up.

[0022] The other part of the high-pressure gas in the pipeline passes through the suction force regulating valve 2. By adjusting the suction force regulating valve 2, the flow rate of the high-pressure gas can be adjusted, so that the size of the negative pressure (the size of the suction force) can be adjusted. According to Bernoulli's principle, the greater the flow rate of the gas, the smaller the pressure. Therefore, a negative pressure is formed at the necked portion 321 of the hollow rotor shaft, so that the dust and other impurities brushed up can be sucked into the dust storage box 5.

[0023] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
