Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more specifically, to an antifreeze cleaner. Background Technology

[0002] In cold environments, traditional sweepers face numerous problems during operation. The surface of the sweeping rollers is prone to snow accumulation and ice formation due to low temperatures. This significantly reduces sweeping efficiency and increases the weight of the sweeping rollers after freezing, increasing the load on the drive unit and shortening the equipment's lifespan. Additionally, after prolonged use, a large amount of dust and debris adheres to the surface of the sweeping rollers. If not cleaned promptly, this not only affects the sweeping effect but may also cause equipment malfunctions due to debris entanglement. Currently, the market lacks a highly efficient sweeping device that can effectively prevent ice formation on the sweeping roller surface while also achieving self-cleaning.

[0003] To address the aforementioned problems, this application provides an antifreeze cleaner. Utility Model Content

[0004] The antifreeze cleaner provided in this application adopts the following technical solution:

[0005] An antifreeze sweeper includes a support frame and a sweeping roller. A drive motor is fixedly installed on the support frame, and the output end of the drive motor drives the sweeping roller to rotate through a synchronous belt pulley set. A cleaning rod and a heating tube are arranged on one side of the sweeping roller on the support frame. An air nozzle is fixedly installed on the surface of the heating tube. A fan is fixedly installed on the outer wall of the support frame, and an electric heating wire heating box is installed at the air outlet of the fan. The other end of the electric heating wire heating box is connected to the heating tube.

[0006] Through the above technical solution, the sweeping roller is driven to rotate at high speed by a synchronous belt pulley set. The brush contacts the ground or the sweeping surface to sweep away debris. The synchronous belt drive has the characteristics of smooth transmission and low noise, which is suitable for the continuous operation requirements of the sweeping equipment. The fan draws in ambient air and delivers it to the heating box of the electric heating wire. The air is heated to a set temperature, such as 30-50°C, and then blown out evenly from the air nozzle through the internal channel of the heating tube. The hot airflow directly acts on the surface of the brush of the rotating sweeping roller, raising the local temperature and preventing snow or water vapor from freezing. At the same time, it can dry the brush and avoid debris from adhering in a humid environment. When the sweeping roller rotates, the brush and the surface of the cleaning rod generate relative motion. Through friction and slapping force, the adhering dust, fibers and other debris are peeled off. Since the cleaning rod is parallel to the sweeping roller and of equal length, the entire working surface of the brush can contact the cleaning rod, ensuring that there are no dead corners in the cleaning. The peeled debris falls off by gravity and is cleaned up.

[0007] Furthermore, the air nozzles are provided in multiple locations, and the multiple air nozzles are equidistantly distributed on the surface of the heating tube.

[0008] The above technical solutions effectively prevent freezing and reduce the possibility of the cleaning roller freezing.

[0009] Furthermore, the drive motor, fan, and heating wire heating box are all electrically connected to an external power source via wires.

[0010] The above technical solution ensures that the drive motor, fan, and heating wire heating box can be powered on and operate normally.

[0011] Furthermore, the cleaning rod is arranged parallel to the sweeping roller.

[0012] The above technical solution can be used to clean the sweeping roller.

[0013] Furthermore, the length of the cleaning rod is the same as the length of the sweeping roller.

[0014] The above technical solutions ensure the cleaning range and effectiveness of the sweeping roller.

[0015] Furthermore, the surface of the cleaning roller is provided with a brush.

[0016] The above technical solutions ensure the cleaning effect on the surface to be cleaned.

[0017] In summary, this application includes the following beneficial technical effects:

[0018] The air blown out by the fan is heated by the heating box of the electric heating wire to form hot air. The hot air is blown onto the surface of the sweeping roller through multiple equally spaced air nozzles on the heating tube. In cold environments, the hot air can increase the temperature of the sweeping roller surface, effectively preventing snow from freezing on the sweeping roller surface, ensuring that the sweeper can still operate normally in low-temperature environments, and improving the environmental adaptability of the equipment.

[0019] The rotating sweeping roller contacts the cleaning rod and generates a slapping friction. Since the cleaning rod and the sweeping roller are parallel and of the same length, the brush on the surface of the sweeping roller will make full contact with the cleaning rod during the rotation. Through the friction and slapping between the two, the dust, debris and other objects adhering to the surface of the sweeping roller can be removed, realizing the self-cleaning of the sweeping roller. It eliminates the need for frequent manual cleaning, improves the convenience and efficiency of the equipment, and also reduces the risk of equipment failure caused by debris entanglement.

[0029] Example:

[0030] This application discloses an antifreeze cleaner; please refer to [link / reference]. Figures 1-4The system includes a support frame 1 and a cleaning roller 3. A drive motor 4 is fixedly installed on the support frame 1, and the output end of the drive motor 4 drives the cleaning roller 3 to rotate through a synchronous pulley set 5. A cleaning rod 2 and a heating tube 6 are arranged on one side of the cleaning roller 3 on the support frame 1. An air nozzle 7 is fixedly installed on the surface of the heating tube 6. A fan 8 is fixedly installed on the outer wall of the support frame 1, and an electric heating wire heating box 9 is installed at the air outlet end of the fan 8. The other end of the electric heating wire heating box 9 is connected to the heating tube 6.

[0031] The antifreeze sweeper mainly consists of a support frame 1, a sweeping roller 3, a drive motor 4, a synchronous pulley set 5, a cleaning rod 2, a heating element 6, an air nozzle 7, a fan 8, and a heating element box 9. These components work together through mechanical and electrical connections to achieve antifreeze and self-cleaning functions. The support frame 1 serves as the basic support structure, providing a mounting platform for other components and ensuring overall structural stability. It is constructed using high-strength metal materials such as aluminum alloy or steel. The drive motor 4 is bolted to the side of the support frame 1, ensuring that the motor output shaft is parallel to the axis of the sweeping roller 3. The cleaning rod 2 and the heating element 6 are fixed to the support frame 1, located on the same side of the sweeping roller 3, parallel to each other and maintaining a fixed distance from the axis of the sweeping roller 3. This distance needs to be adjusted according to the brush length. To ensure contact friction, the blower 8 and the heating wire heating box 9 are bolted to the outer wall of the support frame 1. The air outlet of the blower 8 is connected to the input end of the heating wire heating box 9 through a sealed pipe, and the output end of the heating box is connected to the heating tube 6 through a pipe. The pipe connection uses high-temperature resistant sealing material, such as a silicone sealing ring, to prevent air leakage. The cleaning operation is achieved by rotating the brush, which also works with the cleaning rod 2 to complete self-cleaning. The two ends of the cleaning roller 3 are mounted on the bracket of the support frame 1 through bearings, such as deep groove ball bearings, to ensure flexible rotation. The brush is tightly fixed to the surface of the cleaning roller 3, such as by bolts or adhesive strips, and the material is wear-resistant nylon or rubber to adapt to different cleaning scenarios. The driven pulley of the synchronous pulley group 5 is mounted on the shaft at one end of the cleaning roller 3 and connected to the active pulley at the output end of the drive motor 4. The wheels are connected by a synchronous belt to transmit power. The drive motor 4 provides power, which drives the sweeping roller 3 to rotate through the synchronous belt pulley set 5. The output shaft of the drive motor 4 is keyed to the driving pulley, and the driven pulley is keyed to the shaft of the sweeping roller 3. The tension of the synchronous belt is adjusted by the adjusting bolt on the support frame 1 to ensure transmission efficiency and stability. The cleaning rod 2 is a rigid rod-shaped structure, such as metal or hard plastic, fixed at both ends to the support frame 1. The length of the cleaning rod 2 is exactly the same as that of the sweeping roller 3 to ensure that the entire working surface of the sweeping roller 3 is covered and to avoid cleaning blind spots. The heating tube 6 delivers hot air, which is blown evenly onto the surface of the sweeping roller 3 through the air nozzle 7 to prevent freezing. The heating tube 6 is a hollow metal tube with one end closed. The other end is connected to the output pipe of the heating wire heating box 9. The air nozzle 7 consists of multiple tubular structures, equidistantly welded or threaded onto the surface of the heating tube 6, facing the brush direction of the cleaning roller 3 at an angle of 45° to 60° to ensure that hot air covers the entire brush area. The fan 8 provides airflow to the heating wire heating box 9, which heats the air into hot airflow, which is then delivered to the cleaning roller 3 through the heating tube 6 and the air nozzle 7. An air filter can be installed at the air inlet of the fan 8, and the air outlet is connected to the flange at the input end of the heating wire heating box 9 through a pipe. The heating wire heating box 9 contains a spiral heating wire, and its output end is connected to the flange of the heating tube 6 pipe to ensure smooth airflow. When the drive motor 4 is running, it drives the cleaning roller 3 to rotate at high speed through the synchronous pulley set 5.The brush contacts the ground or cleaning surface to remove debris. Synchronous belt drive offers smooth transmission and low noise, suitable for continuous operation of cleaning equipment. Fan 8 draws in ambient air and delivers it to the heating element box 9. The air is heated to a set temperature, such as 30-50°C, and then evenly blown out through the air nozzle 7 via the internal channel of the heating tube 6. The hot airflow directly acts on the surface of the rotating cleaning roller 3 brush, raising the local temperature and preventing snow or moisture from freezing. It also dries the brush, preventing debris from adhering in humid environments. As the cleaning roller 3 rotates, the brush and cleaning rod 2 move relative to each other, using friction and tapping force to peel off adhering dust, fibers, and other debris. Because the cleaning rod 2 is parallel and of equal length to the cleaning roller 3, the entire working surface of the brush can contact the cleaning rod 2, ensuring thorough cleaning. The removed debris falls away due to gravity.

[0032] Please see Figure 1 , Figure 2 and Figure 3 Multiple air nozzles 7 are provided, and the multiple air nozzles 7 are equidistantly distributed on the surface of the heating tube 6. The multiple air nozzles 7 can fully heat the cleaning roller 3, effectively prevent freezing, and reduce the possibility of the cleaning roller 3 freezing.

[0033] Please see Figure 1 and Figure 2 The drive motor 4, fan 8 and heating wire heating box 9 are all electrically connected to an external power source via wires, which is a common circuit connection structure and will not be described in detail here.

[0034] Please see Figure 1 and Figure 2 The cleaning rod 2 is set parallel to the sweeping roller 3, ensuring that the cleaning rod 2 can fully clean the attached substances on the sweeping roller 3 without the need for an additional cleaning structure, making the structure simple.

[0035] Please see Figure 1 and Figure 2 The cleaning rod 2 is the same length as the sweeping roller 3, and has a significant cleaning effect on the sweeping roller 3. The sweeping roller 3 has a strong self-cleaning ability.

[0036] Please see Figure 1 , Figure 2 and Figure 3 The surface of the sweeping roller 3 is equipped with a brush made of rubber, which can clean the surface of the object being swept.

[0037] The implementation principle of this embodiment is as follows: When in use, an external power source is connected, and the drive motor 4, fan 8, and heating wire heating box 9 begin operation. The drive motor 4 drives the cleaning roller 3 to rotate via the synchronous pulley group 5. The brushes on the surface of the cleaning roller 3 clean the area that needs cleaning. Simultaneously, the fan 8 blows air into the heating wire heating box 9. After the air is heated, it is blown onto the surface of the cleaning roller 3 through the air nozzle 7 on the heating tube 6. The hot air heats the surface of the cleaning roller 3, preventing snow from freezing. During the rotation of the cleaning roller 3, its surface contacts the cleaning rod 2, generating a tapping friction. The cleaning rod 2 removes debris adhering to the surface of the cleaning roller 3, achieving self-cleaning of the cleaning roller 3. Through the coordinated work of the various components, this antifreeze cleaner can operate normally in cold environments and achieve self-cleaning, improving cleaning efficiency and equipment reliability.

[0038] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
