[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] Reference Figures 1-6 The present invention provides a car washing device for small and medium-sized car washes, comprising:

[0044] Grip 1;

[0045] The outer shell 2 is hinged to the handle 1 through a hinge seat 3. The bottom of the outer shell 2 is rotatably connected to the filter plate 4 through a bearing. The bottom surface of the filter plate 4 is fixedly connected to a mop belt 5. The filter plate 4 is fixedly connected to a transmission ring 6.

[0046] A communication hose 7 is connected to the inner cavity of the outer shell 2 and is used to be connected to a foam source;

[0047] Multiple wheel mechanisms are circumferentially arranged at the bottom end of the outer shell 2, and the multiple wheel mechanisms are in transmission cooperation with the transmission ring 6;

[0048] The stirring mechanism is arranged in the inner cavity of the outer shell 2, and the stirring mechanism is in transmission cooperation with the transmission ring 6;

[0049] When the wheel 8 in the wheel mechanism rotates, the filter plate 4 and the stirring mechanism can be rotated through the transmission ring 6 .

[0050] By connecting the connecting hose 7 with the foam source, the foam can flow into the inner cavity of the outer shell 2 and flow out through the filter plate 4. It is only necessary to hold the handle 1 to bring the wheel 8 in the multiple wheel body mechanism into contact with the car body and then perform a push-pull action to make the wheel 8 rotate and rotate the filter plate 4 and the stirring mechanism through the transmission ring 6. The stirring mechanism stirs the foam in the inner cavity of the outer shell 2 to accelerate the mixing of the foam. At the same time, the filter plate 4 drives the mop belt 5 to rotate synchronously. The rotating mop belt 5 effectively improves the scrubbing effect, forming a synchronous implementation of foam spraying and scrubbing, effectively reducing labor intensity, shortening car washing time, and improving the efficiency of car washing.

[0051] Furthermore, the foam source is an external pump and a foam generating device.

[0052] In one embodiment of the present invention, the wheel mechanism includes:

[0053] The mounting box 9 is fixedly connected to the bottom wall of the outer shell 2. A worm 10 is rotatably connected to the mounting box 9. Both ends of the worm 10 extend out of the mounting box 9 and are fixedly connected to the runner 8.

[0054] A groove is formed on the bottom wall of the outer shell 2 and is connected to the inner cavity of the outer shell 2;

[0055] The first connecting rod 12 is rotatably connected in the groove through a bearing. One end of the first connecting rod 12 extends into the installation box 9 and is fixedly connected to a worm gear 13. The worm gear 13 is engaged with the worm 10. The first connecting rod 12 is transmitted and matched with the transmission ring 6 through the transmission group.

[0056] In one embodiment of the present invention, the transmission group comprises:

[0057] The first ring gear 14 is circumferentially fixedly connected to the transmission ring 6;

[0058] The plurality of first gears 15 are fixedly connected to the plurality of first connecting rods 12 one by one, and the first gears 15 are meshed with the first ring gear 14 .

[0059] The rotation of the rotating wheel 8 causes the worm 10 to drive the worm wheel 13 to rotate, thereby the worm wheel 13 drives the first connecting rod 12 to rotate, and then the first gear 15 on the first connecting rod 12 drives the first ring gear 14 to rotate, so that the transmission ring 6 rotates, and the transmission ring 6 drives the filter plate 4 to rotate synchronously.

[0060] In a worm gear transmission, the worm 10 acts as a driving member, and its rotation drives the worm wheel 13 (driven member) to rotate, thereby achieving effective transmission of motion and power.

[0061] In one embodiment of the present invention, the stirring mechanism comprises:

[0062] The second ring gear 16 is fixedly connected to the transmission ring 6;

[0063] The second gear 17 is rotatably connected to the inner cavity of the outer shell 2 through a bearing and a second connecting rod 18, and the second gear 17 is meshed with the second ring gear 16;

[0064] The third gear 19 is rotatably connected to the axis center of the inner cavity of the outer shell 2 through a bearing and a third connecting rod 20, and the third gear 19 is meshed with the second gear 17;

[0065] The stirring blade 21 is disposed on the third connecting rod 19 .

[0066] When the transmission ring 6 rotates, it drives the second gear ring 16 to rotate synchronously, thereby driving the second gear 17 and the third gear 19 to rotate in sequence through the rotation of the second gear ring 16, and then the third gear 19 drives the stirring blade 21 to rotate through the third connecting rod 20 to stir the foam in the outer shell 1.

[0067] In one embodiment of the present invention, a reciprocating thread groove 22 is provided on the second connecting rod 18, and a reciprocating sleeve 23 is provided on the reciprocating thread groove 22 for transmission. A fourth connecting rod 24 is fixedly connected to the reciprocating sleeve 23, and a sliding sleeve 25 is rotatably connected to the fourth connecting rod 24 through a bearing. The sliding sleeve 25 is slidably fitted on the third connecting rod 20, and the sliding sleeve 25 is fixedly connected to the stirring blade 21. The inner side wall of the sliding sleeve 25 is provided with a latch tooth 26, and the side wall of the third connecting rod 20 is provided with a latch groove 27. The latch tooth 26 is meshed with and slidably fitted with the latch groove 27.

[0068] When the second connecting rod 18 rotates with the second gear 17, the reciprocating thread groove 22 and the reciprocating sleeve 23 are coupled to each other, so that the reciprocating sleeve 23 drives the sliding sleeve 25 to move up and down through the fourth connecting rod 24. Since the sliding sleeve 25 is engaged with the third connecting rod 20 through the slot 27 and the tooth 26, the sliding sleeve 25 keeps rotating synchronously with the third connecting rod 20 while sliding, so that the sliding sleeve 25 drives the stirring blade 21 to rotate and move up and down, which not only effectively improves the stirring efficiency but also can squeeze the foam toward the filter plate 4, so as to facilitate the discharge of the foam.

[0069] In one embodiment of the present invention, the stirring blade 21 is spiral and has a plurality of through holes 28 .

[0070] The spiral stirring blades 21 can effectively guide the foam toward the filter plate 4 , and a plurality of through holes 28 are provided to improve the circulation effect of the foam in the inner cavity of the outer shell 1 .

[0071] In one embodiment of the present invention, the third connecting rod 20 is fixedly connected to a brush plate 29 , and the brush plate 29 abuts against the filter plate 4 .

[0072] Due to the transmission through the second gear 17 and the third gear 19, the third connecting rod 20 rotates in the opposite direction to the filter plate 4, so that the third connecting rod 20 drives the brush plate 29 to clean the filter plate 4 in the opposite direction to avoid clogging of the filter plate 4.

[0073] In one embodiment of the present invention, the brush plate 29 and the third connecting rod 20 are connected via a plurality of spring telescopic rods 30 .

[0074] A plurality of spring-loaded telescopic rods 30 enable the brush plate 29 to maintain contact with the filter plate 4 .

[0075] In one embodiment of the present invention, a plurality of support rings 31 are provided on the handle 1 , and the connecting hose 7 is passed through the plurality of support rings 31 .

[0076] In one embodiment of the present invention, a protective pad is provided circumferentially on the rotating wheel 8 to avoid damaging the vehicle surface.
