Description

Technical Field

[0001] This utility model belongs to the technical field of car washing devices, and particularly relates to a pipe ice crushing mechanism and a car maintenance device. Background Technology

[0002] Currently, the removal of ice debris from the pipes of dry ice cleaning machines primarily relies on high-speed or high-temperature airflow flowing through the entire spray pipe. This technology continuously introduces high-pressure gas or a heated medium into the pipe, utilizing the kinetic or thermal energy of the airflow to break up or sublimate the ice debris, thereby reducing the risk of clogging. To achieve this, existing solutions typically employ a unidirectional airflow delivery system covering the entire pipe path from the dry ice storage end to the nozzle outlet, relying on increased overall airflow intensity to enhance the flushing effect. This design is considered standard practice in the industry and is widely used in most dry ice cleaning equipment.

[0003] However, the aforementioned methods for removing ice debris have significant shortcomings. Because dry ice jetting pipes are generally quite long, and ice debris only concentrates in specific areas (such as bends, joints, or low-velocity sections), traditional high-speed or high-temperature airflows cannot precisely target the critical locations where ice debris forms. Non-directional, global scouring leads to energy dispersion, which is neither effective in removing locally accumulated ice debris nor sustainable due to over-reliance on high-intensity airflow, thus increasing energy consumption and equipment wear. Furthermore, the introduction of high-temperature airflow throughout the process may interfere with the stability of dry ice particles, exacerbating temperature and humidity fluctuations within the pipe and potentially inducing secondary icing. These problems severely restrict the maintenance of pipe flow, directly impacting dry ice cleaning efficiency and the long-term reliability of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a pipeline ice crushing mechanism and a car maintenance device, which aims to solve the technical problem that the existing pipeline de-icing mechanism uses high temperature to enter the pipeline, and the introduction of high temperature airflow throughout the process may interfere with the stability of dry ice particles, aggravate the temperature and humidity fluctuations in the pipeline, and induce the risk of secondary icing.

[0005] To achieve the above objectives, this utility model provides a pipe ice shavings crushing mechanism, comprising a main body, a limiting mechanism, and a spraying mechanism. The main body contains a dry ice gas forming mechanism. The limiting mechanism is disposed on the side wall of the main body and has an open cavity. The pipe portion of the spraying mechanism is bent and stacked on the side wall of the main body. At least a portion of the pipe of the spraying mechanism has a bent section extending into the open cavity, where a heating unit is disposed. The remaining portion of the pipe of the spraying mechanism is a straight pipe.

[0006] Optionally, the main body is provided with a cuboid structure, the side walls of the main body are provided with vertical end faces, the pipe portion of the spraying mechanism is stacked along the side wall of the main body in an S-shape, and the bent portion is formed on both sides of the pipe portion of the spraying mechanism.

[0007] Optionally, the spraying mechanism includes a spray gun, a rigid pipe, and a flexible pipe. There are multiple sets of both the flexible pipe and the rigid pipe. The flexible pipe and the rigid pipe are connected alternately. At least one set of the flexible pipe extends into the main body and is connected to the output end of the dry ice gas forming mechanism. The input end of the spray gun is connected to another set of flexible pipes away from the output end of the dry ice forming mechanism. The bending portion is formed on the flexible pipe.

[0008] Optionally, the rigid pipe includes a straight sleeve and a first transmission pipe. The first transmission pipe is made of a rigid material and its inner wall is coated with a smooth film. The straight sleeve is fitted onto the first transmission pipe. The number of flexible pipes is at least two sets, and the two ends of the first transmission pipe are respectively connected to the corresponding flexible pipes.

[0009] Optionally, the rigid pipe further includes a pulley, which is rotatably connected to the side wall of the straight sleeve, and the straight sleeve can slide against the ground via the pulley.

[0010] Optionally, the rigid pipe further includes a magnetic element disposed on the pulley, and two adjacent sets of rigid pipes are stacked together by magnetic attraction through the magnetic element.

[0011] Optionally, the limiting mechanism includes two sets of C-shaped frames, which are symmetrically distributed at both ends of the side wall of the main body. The opposite ends of the two sets of C-shaped frames are provided with grooves for accommodating the bent portion. The two sets of grooves are formed into the open cavity, and the heating unit is disposed on the side wall of the groove.

[0012] Optionally, the heating unit is an electric heating element, an electric heating tube, or an electric heating wire.

[0013] Optionally, the bending portion is made of a thermally conductive metal material and is configured in the shape of a corrugated tube.

[0014] To achieve the above objectives, this utility model provides an automobile maintenance device, including the aforementioned pipe ice crushing mechanism.

[0015] The pipe ice shredding mechanism and automotive maintenance device provided in this utility model embodiment have at least one of the following technical effects: By embedding the bent part of the spraying mechanism into an open cavity and configuring a heating unit, it is possible to precisely target and heat the pipe bend areas where ice shards easily accumulate, directly destroying the ice shard structure and accelerating its sublimation and elimination, avoiding the energy waste and secondary icing risk caused by the global scouring of high-speed / high-temperature airflow in traditional solutions. This dry ice cleaning machine retains the conventional structural stability of the main pipe body while achieving efficient de-icing through localized thermal intervention, significantly reducing system energy consumption and pipe wear, while simplifying equipment maintenance procedures and effectively ensuring the continuity of the dry ice spraying process and the stability of cleaning efficiency.

[0028] The embodiments of this utility model are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The following description is based on the accompanying drawings. Figures 1-5 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

[0029] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. 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.

[0031] 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.

[0032] In one embodiment of this utility model, such as Figures 1-5As shown, an automotive maintenance device is provided, including a pipe ice shredding mechanism. The pipe ice shredding mechanism includes a main body 100, a limiting mechanism 200, and a spraying mechanism 300. A dry ice gas forming mechanism is disposed within the main body 100. The limiting mechanism 200 is disposed on the side wall of the main body 100 and has an open cavity 400. The pipe portion of the spraying mechanism 300 is bent and stacked on the side wall of the main body 100. At least a portion of the pipe of the spraying mechanism 300 has a bent portion that extends into the open cavity 400. A heating unit 500 is disposed within the open cavity 400. The remaining portion of the pipe of the spraying mechanism 300 is a straight pipe.

[0033] By embedding the bent portion of the spraying mechanism 300 into the open cavity 400 and configuring a heating unit 500, precise directional heating can be applied to the pipe bends where ice easily accumulates, directly disrupting the ice structure and accelerating its sublimation and elimination. This avoids the energy waste and risk of secondary icing caused by the global scouring of high-speed / high-temperature airflow in traditional solutions. This dry ice cleaning machine retains the conventional structural stability of the main pipe body 100 while achieving efficient de-icing through localized thermal intervention, significantly reducing system energy consumption and pipe wear. It also simplifies equipment maintenance procedures and effectively ensures the continuity of the dry ice spraying process and the stability of cleaning efficiency.

[0034] like Figures 1-5 As shown, in another embodiment of this utility model, the main body 100 is arranged in a cuboid structure, the sidewalls of the main body 100 are arranged with vertical end faces, and the pipe portion of the spraying mechanism 300 is stacked along the S-shape extending direction of the sidewalls of the main body 100. The bent portion is formed on both sides of the pipe portion of the spraying mechanism 300. When dry ice gas is transported through the S-shaped pipe, the flow velocity in the bending area decreases, and ice chips preferentially accumulate in the bending portion; the heating unit 500 directly applies heat energy to the bending portion through the open cavity 400, causing the ice chips to sublimate rapidly; the S-shaped stacking design optimizes space utilization, and at the same time, by directional heating of the bending area, it improves the efficiency of ice chip removal, avoids overall pipe deformation due to heat, and ensures the compactness and stability of the equipment.

[0035] like Figures 1-5As shown, in another embodiment of this utility model, the spraying mechanism 300 includes a spray gun 310, a rigid pipe 320, and a flexible pipe 330. Multiple sets of both the flexible pipe 330 and the rigid pipe 320 are connected alternately. At least one set of the flexible pipe 330 extends into the main body 100 and connects to the output end of the dry ice gas forming mechanism. The input end of the spray gun 310 is connected to another set of flexible pipes 330 located away from the output end of the dry ice forming mechanism. The bent portion is formed on the flexible pipe 330. The rigid pipe 320 maintains straight-line transmission stability, while the flexible pipe 330 adapts to external bending. The bent portion is located at the flexible pipe 330, and the heating unit 500 precisely acts on this area. The combination of the rigid and flexible pipes 330 balances transmission stability and operational flexibility. The localized heating design of the flexible pipe 330 effectively reduces the risk of ice buildup and extends the pipe's service life.

[0036] like Figures 1-5 As shown, in another embodiment of this utility model, the rigid pipe 320 includes a straight sleeve 321 and a first transmission pipe 322. The first transmission pipe 322 is made of rigid material and its inner wall is coated with a smooth coating. The straight sleeve 321 is fitted onto the first transmission pipe 322. The number of flexible pipes 330 is at least two sets, and the two ends of the first transmission pipe 322 are respectively connected to the corresponding flexible pipes 330. The smooth coating reduces the friction between dry ice particles and the pipe wall, the straight sleeve 321 provides mechanical protection, and the pulley 323 assists in reducing ground friction when the pipe moves. The smooth inner wall reduces the probability of ice residue adhesion, the sleeve structure enhances the impact resistance of the pipe, and the pulley 323 design improves the ease of equipment movement.

[0037] like Figures 1-5 As shown, in another embodiment of this utility model, the rigid pipe 320 further includes a pulley 323, which is rotatably connected to the side wall of the straight sleeve 321. The straight sleeve 321 can slide against the ground via the pulley 323. The rigid pipe 320 also includes a magnetic component 324, which is disposed on the pulley 323. Adjacent sets of rigid pipes 320 are stacked by magnetic attraction through the magnetic component 324. When the equipment is moved, the pulley 323 rolls to reduce drag resistance; when the equipment is stopped, the magnetic component 324 attracts and fixes the pipe to prevent it from scattering. The pulley 323 and the magnetic component 324 work together to achieve rapid deployment and storage, reducing manual sorting time and improving work efficiency.

[0038] like Figures 1-5As shown, in another embodiment of this utility model, the limiting mechanism 200 includes two sets of C-shaped frames 210. The two sets of C-shaped frames 210 are symmetrically distributed at both ends of the side wall of the main body 100. The opposite ends of the two sets of C-shaped frames 210 are provided with grooves for accommodating the bent portion. The two sets of grooves are formed into the open cavity 400. The heating unit 500 is disposed on the side wall of the groove. After the bent portion is embedded in the groove, the heating unit 500 directly radiates heat to the surface of the pipe, while the C-shaped frame 210 restricts the displacement of the pipe. The groove structure ensures that the heating unit 500 is tightly fitted with the bent portion, resulting in high heat transfer efficiency. The frame reinforcement prevents the pipe from vibrating and shifting.

[0039] like Figures 1-5 As shown, in another embodiment of this utility model, the heating unit 500 is an electric heating element, an electric heating tube, or an electric heating wire; the heating unit 500 generates heat energy after being powered on, and acts on the pipe at the bend through heat conduction or radiation; multiple types of heating units 500 are adapted to different power and scenario requirements, enhancing system compatibility and maintainability.

[0040] like Figures 1-5 As shown, in another embodiment of this utility model, the bending part is made of a thermally conductive metal material and is arranged in the shape of a corrugated pipe. In this embodiment, the bending part is formed on the flexible pipe 330. The thermally conductive metal quickly transfers heat to the ice crystals, and the corrugated structure relieves the stress of thermal expansion and contraction, preventing the pipe from cracking. The corrugated pipe design improves the uniformity of heat conduction and structural durability, while adapting to temperature deformation and reducing thermal stress damage.

[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.
