Abstract
Description
Technical Field
[0001] This utility model belongs to the field of car cleaning technology, and in particular relates to a multi-angle telescopic nozzle dry ice cleaning device. Background Technology
[0002] Existing dry ice cleaning devices for car washing typically integrate omnidirectional rotation and telescopic functions at their output end. The omnidirectional rotation function is achieved through flexible tubing and a multi-directional hinged structure, allowing operators to flexibly adjust the spray angle to suit complex surfaces. The telescopic function relies on a spiral or coiled tubing design, with a mechanical extension and retraction mechanism controlling the tubing length to expand the cleaning coverage. These devices transport dry ice particles via a gas-solid two-phase flow, combining low-temperature impact and physical abrasion effects to complete the cleaning operation, and are widely used for removing stubborn dirt from engine compartments, wheel hubs, and other areas.
[0003] However, the existing methods for implementing the telescopic function have significant drawbacks. Coiled or wound pipes are continuously subjected to tension and bending stress during repeated unwinding and rewinding, which can easily lead to pipe fatigue damage, inner wall wear, and even rupture, affecting the continuity and stability of dry ice delivery. Furthermore, uneven stress during rewinding can cause localized deformation or twisting, further exacerbating the risk of particle blockage, increasing equipment maintenance costs, and reducing long-term reliability. Utility Model Content

[0008] Optionally, the sliding assembly includes a guide rail pair and a movable seat.

[0010] Optionally, the open cavity has a fixed tube, which is fixedly disposed in the open cavity and extends along the length of the open cavity. One end of the fixed tube is connected to the movable tube, and the other end of the fixed tube extends to the opening position of the open cavity and is located on one side of the end of the cable chain.

The following description is based on the accompanying drawings. Figures 1-3 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0030] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0031] In one embodiment of this utility model, such as Figures 1-3As shown, a multi-angle telescopic nozzle dry ice cleaning device is provided, including a main body 100, a nozzle mechanism 200, and a dry ice gas generating mechanism 300. The main body 100 is provided with an installation cavity 110. The input end of the nozzle mechanism 200 is slidably connected to the main body 100 and extends into the installation cavity 110, while the output end of the nozzle mechanism 200 extends outside the installation cavity 110. The dry ice gas generating mechanism 300 is disposed within the installation cavity 110 and is used to generate dry ice gas for cleaning a preset workpiece. A cable chain 400 is disposed within the installation cavity 110, and a flexible tube 500 distributed along the laying path of the cable chain 400 is disposed within the cable chain 400. The input end of the flexible tube 500 is connected to the output end of the dry ice gas generating mechanism 300, and the other end of the flexible tube 500 is connected to the input end of the nozzle mechanism 200.
[0032] Specifically, by introducing a cable chain 400 structure in conjunction with a flexible tube 500 design, the fatigue damage and deformation of traditional wound pipes caused by continuous tension are effectively solved. The rigid guidance of the cable chain 400 and the adaptive deformation of the flexible tube 500 combine to ensure that the pipe moves smoothly along a preset path during expansion and contraction, avoiding local twisting or stress concentration as in traditional winding methods, and significantly reducing the risk of pipe rupture and dry ice particle blockage. Stable gas-solid two-phase flow is maintained, improving the continuity of cleaning operations and extending the service life of the pipe, effectively overcoming the shortcomings of frequent maintenance and insufficient reliability of existing dry ice cleaning machines.
[0033] like Figures 1-3 As shown, in another embodiment of this utility model, the nozzle mechanism 200 includes a universal nozzle 210 and a sliding assembly 220. The sliding assembly 220 is slidably connected in the mounting cavity 110. The output end of the universal nozzle 210 extends outside the main body 100, and the input end of the universal nozzle 210 is disposed on the output end of the sliding assembly 220. The end of the drag chain 400 is fixedly connected to the output end of the sliding assembly 220. One end of the flexible tube 500 is connected to the output pipe of the dry ice gas generating mechanism 300, and the other end of the flexible tube 500 extends into the sliding assembly 220 and is connected to the pipe of the universal nozzle 210. The universal nozzle 210 can achieve multi-angle free adjustment. Compared with the limitation of traditional dry ice cleaning machines that can only achieve multi-angle adjustment and cannot perform telescopic adjustment, the nozzle structure provided in this embodiment adds telescopic function on the basis of multi-angle adjustment, effectively improving the output range of the nozzle structure.
[0034] like Figures 1-3As shown, in another embodiment of this utility model, the universal nozzle 210 includes a connecting pipe 211 and a spray gun 212. The end of the connecting pipe 211 is disposed on the sliding assembly 220, and the end of the connecting pipe 211 is connected to the flexible tube body 500. The other end of the connecting pipe 211 is connected to the spray gun 212 pipe. The connecting pipe 211 is made of rubber material. The rubber connecting pipe 211 flexibly bends with the angle adjustment of the universal nozzle 210, its elastic deformation adapting to the multi-directional movement of the nozzle, while its low-temperature resistance ensures that the dry ice delivery does not become brittle. Traditional metal or rigid plastic pipes are prone to joint cracking due to rigidity when the nozzle turns. The flexible design of the rubber connecting pipe 211 eliminates this hidden danger, and at the same time, improved sealing reduces dry ice gas leakage, overcoming the shortcomings of insufficient flexibility in traditional nozzles.
[0035] like Figures 1-3 As shown, in another embodiment of this utility model, the sliding assembly 220 includes a guide rail pair 221 and a movable seat 222. The guide rail of the guide rail pair 221 is laid on the side wall of the mounting cavity 110, and the movable seat 222 is fixedly connected to the slider of the guide rail pair 221. A sliding hole is provided on the side wall of the mounting cavity 110, and the end of the movable seat 222 is slidably connected to the sliding hole. The end of the movable seat 222 can extend to the outside of the mounting cavity 110 through the sliding hole. The universal nozzle 210 is fixedly disposed at the end of the movable seat 222 that extends to the outside of the mounting cavity 110. The guide rail pair 221 guides the movable seat 222 to slide along a linear path. The movable seat 222 extends to the outside of the main body 100 through the sliding hole. The drag chain 400 extends and retracts synchronously with the movable seat 222, and the nozzle position is precisely adjusted according to the stroke of the movable seat 222. Traditional hoses are easily deformed by external forces when they are directly exposed and extended. In this embodiment, the guide rail pair 221 and the sliding hole constrain the nozzle extension path to ensure that the pipe swings randomly or bends excessively, thus solving the blockage problem caused by insufficient pipe bending radius in traditional designs.
[0036] like Figures 1-3As shown, in another embodiment of this utility model, the movable seat 222 includes a movable frame 223 and a movable tube 224. The movable frame 223 is fixedly connected to the slider of the guide rail pair 221. The movable tube 224 is fixedly disposed on the movable frame 223 and slidably connected to the sliding hole. The movable frame 223 is provided with an open cavity 225. The guide rail of the guide rail pair 221 is laid facing the sliding hole. The main body 100 of the cable chain 400 is arranged parallel to the guide rail of the guide rail pair 221. The end of the cable chain 400 is bent and extends into the open cavity 225 and is fixedly connected to the inner wall of the open cavity 225. The end of the cable chain 400 is bent into the open cavity 225 of the movable frame 223 and fixed. When the movable seat 222 slides, the main body 100 of the cable chain 400 moves parallel to the guide rail. The bent section adaptively expands and contracts, avoiding interference between the cable chain 400 and the movable frame 223. Traditional coiled pipes are prone to accumulating and tangling during long-stroke extension and retraction. In this embodiment, the coordinated design of the drag chain 400 and the moving frame 223 ensures that the pipe extension and retraction path is strictly synchronized with the nozzle movement trajectory, eliminating pipe twisting or wear caused by path deviation in traditional winding mechanisms.
[0037] like Figures 1-3 As shown, in another embodiment of this utility model, a fixed tube 226 is provided inside the open cavity 225. The fixed tube 226 is fixedly disposed inside the open cavity 225 and extends along the length direction of the open cavity 225. One end of the fixed tube 226 is connected to the moving tube 224, and the other end of the fixed tube 226 extends to the opening position of the open cavity 225 and is located on one side of the end of the cable chain 400. The flexible tube body 500 is connected to the fixed tube 226. The fixed tube 226 passes through the open cavity 225 of the moving frame 223. The flexible tube body 500 is connected to the moving tube 224 through the fixed tube 226. When the moving seat 222 slides, the flexible tube body 500 only moves slightly along the axial direction of the fixed tube 226 to avoid lateral bending. In traditional designs, flexible pipes are prone to lateral swaying when they extend and retract with the nozzle, leading to increased wear on the inner wall. In this embodiment, the movement direction of the flexible pipe 500 is constrained by the fixed pipe 226, reducing unnecessary deformation and solving the problem of unstable particle delivery caused by pipe friction in traditional structures.
[0038] like Figures 1-3As shown, in another embodiment of this utility model, the top of the main body 100 is provided with a mounting hole 700, and the spray gun 212 is snapped into the mounting hole 700. The spray gun 212 is snapped into the main body 100 through the mounting hole 700, and can be directly inserted and removed without the need for tools. The inner wall of the mounting hole 700 is adapted to and limited by the outer contour of the spray gun 212. Traditional spray guns 212 are fixed with bolts, which are cumbersome to replace and are prone to loosening due to vibration. The snap-fit design of this embodiment simplifies the maintenance process, and at the same time, the tight fit prevents the spray gun 212 from shaking during operation, improving the convenience and safety of operation.
[0039] like Figures 1-3 As shown, in another embodiment of this utility model, a roller 800 is provided at the bottom of the main body 100. The roller 800 is installed at the bottom of the main body 100, and rolls when the device is pushed, reducing movement resistance and adapting to the needs of moving in uneven workshop floors or narrow spaces. Traditional dry ice cleaning machines are bulky and lack moving assistance structures, making them difficult to transport. This embodiment achieves flexible movement through the design of the roller 800, solving the problem of limited application scenarios caused by the inconvenience of movement of traditional equipment.
[0040] like Figures 1-3 As shown, in another embodiment of this utility model, the end of the dry ice gas generating mechanism 300 extends to the top of the main body 100, and the air inlet valve 900 of the dry ice gas generating mechanism 300 is disposed at the top of the main body 100. With the air inlet valve 900 of the dry ice gas generating mechanism 300 located at the top of the main body 100, the operator can directly adjust the gas source input from above, and the valve body is perpendicularly connected to the external gas interface. When the conventional air inlet valve 900 is located on the side or bottom of the equipment, operation requires bending over or turning sideways, which can easily lead to accidental contact with other components. This embodiment optimizes human-machine interaction through a top-mounted layout, avoiding the inconvenience and safety hazards of traditional designs.
[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
