Description

Technical Field

[0001] The invention relates to the technical field of engine cleaning, and in particular to a dry ice cleaning machine for carbon deposits on automobiles. Background Art

[0002] Cleaning carbon deposits from automobile engines is an important step in maintaining engine performance. A dry ice carbon cleaning machine is a professional device that uses dry ice to clean carbon deposits. The dry ice carbon cleaning machine uses high-pressure air to spray dry ice particles onto the working surface that needs to be cleaned (such as the intake duct of an automobile engine, the throttle, etc.). It uses the characteristics of rapid sublimation of dry ice at room temperature and pressure to absorb surrounding heat and produce a low-temperature effect. This low-temperature effect can freeze and embrittle the carbon deposits and colloids attached to the surface, and the embrittled carbon deposits become easy to peel off. At the same time, the dry ice particles vaporize at the moment of impact, and the volume expands nearly 800 times, generating a strong peeling force to completely remove the carbon deposits from the surface of the object.

[0003] The tube of the dry ice blasting machine is usually called the dry ice blasting tube or dry ice cleaning tube. This tube plays a key role in the dry ice blasting machine, responsible for delivering dry ice particles and compressed air to the nozzle to achieve the cleaning operation.

[0004] When using the dry ice cleaning machine for carbon deposits on cars, the diameter of the spray pipe is relatively thick. When dragging, part of the pipe body touches the ground, and the pipe near the nozzle end is lifted by the user.

[0018] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0019] like Figure 1-Figure 8The dry ice cleaning machine for carbon deposits on automobiles shown in the figure comprises a machine body 1, a spray pipe 2 is fixedly connected to the front surface of the machine body 1, a nozzle 3 is fixedly connected to the front end of the spray pipe 2, a sleeve 4 is solidly sleeved on the outer surface of the spray pipe 2, a tooth plate 6 is fixedly embedded on the upper surface of the sleeve 4, a sliding sleeve 5 is slidably sleeved on the outer surface of the sleeve 4, a guide groove 7 is opened on the inner side of the sliding sleeve 5, the guide groove 7 is slidably sleeved on the outer side of the tooth plate 6, a T-shaped plate 8 is slidably inserted on the inner top surface of the guide groove 7 through a first elastic mechanism, and the T-shaped plate 8 is slidably sleeved on the inner top surface of the guide groove 7. The lower end is clamped into the surface of the toothed plate 6, the upper side of the front surface of the sliding sleeve 5 is slidably connected with the lifting plate 11 through a second elastic mechanism, the front end of the T-shaped plate 8 is slidably matched with the T-shaped plate 8, the two side surfaces of the lifting plate 11 are rotatably connected with claws 23, the two side surfaces of the sliding sleeve 5 are rotatably connected with the second rotating shaft 26, the outer surface of the second rotating shaft 26 is fixedly sleeved with a ratchet 24, one end of the claw 23 is clamped into the surface of the ratchet 24, and the outer surface end of the second rotating shaft 26 is fixedly sleeved with a support mechanism; After the lifting plate 11 moves upward, the lower end of the T-shaped plate 8 is separated from the surface of the toothed plate 6 , and one end of the claw 23 is separated from the surface of the ratchet 24 .

[0020] Obviously, the protruding teeth on the surface of the ratchet wheel 24 and the tooth plate 6 are designed as ratchet teeth, ensuring that when contacting with the ratchet teeth, it can only slide across the surface in one direction.

[0021] like Figure 3 , Figure 4 As shown, a first slide groove 9 is provided on the inner side of the sliding sleeve 5 corresponding to the upper side of the guide groove 7, and the elastic mechanism includes a first compression spring 10 fixedly connected to the upper surface of the T-shaped plate 8, and the upper end of the first compression spring 10 is fixedly connected to the inner top surface of the first slide groove 9, and the upper end of the T-shaped plate 8 slides into the inner side of the first slide groove 9. When the T-shaped plate 8 is pushed up, it will move up along the inner side of the first slide groove 9 and squeeze the first compression spring 10.

[0022] A second slide groove 12 is provided at the lower edge of the rear surface of the lifting plate 11, and the rear end of the second slide groove 12 is connected to the first slide groove 9. A guide column 13 is fixedly connected to the inner side of the second slide groove 12, and the upper end of the T-shaped plate 8 is slidably sleeved on the outer surface of the guide column 13. When the T-shaped plate 8 moves upward, it will slide relatively along the surface of the guide column 13. The design of the second slide groove 12 can make the lifting plate 11 not interfere with the upward movement of the T-shaped plate 8, but can drive the T-shaped plate 8 to move upward synchronously.

[0023] like Figure 5 , Figure 6 , Figure 7As shown, the two sides of the rear surface of the lifting plate 11 extend with snap-in edges 15, and the two side surfaces of the sliding sleeve 5 are respectively provided with side grooves 14, and the snap-in edges 15 slide and snap into the inner side of the side grooves 14, and the upper surface of the lifting plate 11 is fixedly connected with a first concave plate 18, and the inner side of the first concave plate 18 is fixedly connected with a first pull rod 19, and the upper surface of the sliding sleeve 5 is fixedly connected with a second concave plate 20, and the inner side of the second concave plate 20 is fixedly connected with a second pull rod 21. The design of the first pull rod 19 and the second pull rod 21 allows the user to operate with one hand to move the lifting plate 11 upward.

[0024] The second elastic mechanism includes a T-shaped column 16 fixedly connected to the upper surface of the lifting plate 11 near both sides, and the outer surface of the T-shaped column 16 is sleeved with a second compression spring 17, and the upper end of the T-shaped column 16 slides through the upper surface of the sliding sleeve 5. The second compression spring 17 provides elastic force to ensure that the lifting plate 11 can be relatively located at the lower position.

[0025] A first rotating shaft 22 is fixedly passed through one side surface of the clamping claw 23 , and one end of the first rotating shaft 22 is rotatably inserted into the side surface of the lifting plate 11 .

[0026] like Figure 8 As shown, the support leg mechanism includes a connecting leg 25 fixedly sleeved on the outer surface of the second rotating shaft 26, a third rotating shaft 32 is rotatably embedded on the lower surface of the connecting leg 25, a wheel seat 30 is fixedly connected to the lower end of the third rotating shaft 32, a wheel axle 31 is rotatably penetrated through one side of the wheel seat 30, and the two ends of the wheel axle 31 are respectively fixedly connected to the wheel body 29. The wheel body 29 can roll forward and backward, and at the same time, the wheel body 29 can rotate around the third rotating shaft 32 to change the rolling direction.

[0027] like Figure 3 As shown, a stopper 33 is fixedly connected to the upper surface of the sleeve 4 and near the rear of the tooth plate 6. The design of the stopper 33 can ensure that when the sliding sleeve 5 moves backward relative to the sleeve 4, there will be no problem of excessive movement causing the two to separate.

[0028] like Figure 5 As shown, the two side surfaces of the sliding sleeve 5 are respectively fixedly connected with protective covers 27, and a reserved opening 28 is provided on the upper surface of the protective cover 27. The ratchet 24 is located on the inner side of the protective cover 27, and one end of the claw 23 passes through the inner side of the reserved opening 28. The protective cover 27 protects against debris from being entangled on the surface of the ratchet 24 during use, and the reserved opening 28 reserves sufficient rotation space for the claw 23, and does not interfere with the movement of the claw 23.

[0029] During use, the user drags the spray tube 2 and sprays dry ice on the carbon deposit holes through the nozzle 3. During dragging, the spray tube 2 is in a falling state near the rear of the hand grip. At this time, under the action of gravity, the connecting foot 25 and the second rotating shaft 26 rotate forward and downward, and the ratchet 24 also rotates synchronously. The surface of the ratchet 24 can push the claw 23, so that the claw 23 rotates upward with the first rotating shaft 22 as the axis. After the claw 23 rotates, it will be stuck in the surface of the ratchet 24 again under the action of gravity. Therefore, the ratchet 24 can only rotate in one direction, that is, it is guaranteed that in the later use, the connecting foot 25 will not rotate toward the front and upward due to the mutual pushing of the wheel body 29 and the ground, so as to ensure that the wheel body 29 is always in contact with the ground during dragging to assist in dragging the spray tube 2.

[0030] In the process of lifting the nozzle 3, under the action of gravity, the sliding sleeve 5 will slide downward along the lower surface of the sleeve 4. When the T-plate 8 contacts the surface of the tooth plate 6, the T-plate 8 is pushed upward to squeeze the first compression spring 10, thereby ensuring that the sliding sleeve 5 can slide down relatively to move to the bending position of the injection pipe 2 to ensure that the wheel body 29 can contact the ground. When the ground exerts a relatively upward force on the wheel body 29, the lower end of the T-plate 8 is stuck in the surface of the tooth plate 6 and is blocked and will not move upward, thereby ensuring that the wheel body 29 can play a supporting role.

[0031] The user can open his palms, hold the first pull rod 19 and the second pull rod 21, and perform a gripping action, so that the second pull rod 21 moves up relative to the first pull rod 19, the lifting plate 11 moves up, the claw 23 disengages from the surface of the ratchet 24, and the T-shaped plate 8 disengages from the surface of the toothed plate 6. At this time, the connecting foot 25 can be rotated toward the front and upper direction to be reset, or the sliding sleeve 5 can be slid forward along the surface of the sleeve 4 to be reset, so as to facilitate next use.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention.
