The liquid level switch 502 is installed on the top of the stainless steel water tank 401, and its main function is to detect the liquid level in the water tank in real time. This function is crucial for the heating system, because the water level will directly affect the working efficiency and safety of the heating rod 501. If the water level is too low, the heating rod 501 may be damaged due to dry burning; if the water level is too high, it may cause safety hazards due to water splashing. Therefore, the accurate detection of the liquid level switch 502 provides reliable safety protection for the heating system. The heating system 5 realizes precise control and adjustment of water temperature through the cooperative work of the heating rod 501 and the liquid level switch 502, meeting the diversified needs of the cleaning operation for water temperature. At the same time, this system also ensures the safety and stability of the heating process through the real-time monitoring function of the liquid level switch 502. This design not only improves the efficiency and quality of the cleaning operation, but also prolongs the service life of the heating system 5 and reduces the maintenance cost. Therefore, the heating system 5 plays a crucial role in the semi-automatic mobile cleaning machine.

[0032] The support structure 6 is a key component in the semi-automatic mobile washing machine that ensures the stability and functionality of the device. The detailed structure and working principle of the support structure 6 brings the following technical effects: The upright columns 601 are stably arranged on the left and right sides of the vehicle box shell 2, which serve as the main support points of the support structure 6 and provide a solid support foundation for the entire device. This design not only enhances the stability of the device, but also ensures the safety of the device during movement and operation. The rear mounting column 602 is arranged at the rear of the vehicle box shell 2 and is connected to the upright columns 601 through the connecting bent plate 603. This design not only strengthens the overall rigidity of the support structure 6, but also makes the entire support structure more compact and stable. The connecting bent plate 603 serves as a connecting piece, and its precise machining and installation ensure the firm connection between the upright columns 601, the rear mounting column 602, and the protective plate 8, improving the overall impact resistance of the device. The upper connecting plate 604 is arranged at the top of the support structure 6 and serves as the connection and fixing point of the water spraying device 7 and the protective plate 8, playing a crucial role. The flatness and strength of the upper connecting plate 604 are strictly designed and controlled to ensure that the water spraying device 7 can be stably installed on it and maintain a stable posture during operation. This design not only improves the efficiency and quality of the cleaning operation, but also prolongs the service life of the water spraying device 7. In summary, the support structure 6 realizes the stable support and precise connection of the components of the semi-automatic mobile washing machine through the cooperation of the upright columns 601, the rear mounting column 602, the connecting bent plate 603, and the upper connecting plate 604. This design not only improves the stability and safety of the device, but also ensures the efficient operation of the cleaning operation.

[0033] The water spraying device 7 is the core executive component of the semi-automatic mobile cleaning machine. Its detailed structure and working principle bring the following technical effects: the water spraying pipe 701, as the main component of the water spraying device 7, is tightly connected with the water pump outlet pipeline of the water pipeline system 4 through the pipeline. This design ensures that the water pumped by the water pump can flow smoothly into the water spraying pipe 701, providing a stable water source for subsequent water spraying operations. On the water spraying pipe 701, several water spraying nozzles 702 are carefully installed and directed towards the surface to be cleaned. The design of these water spraying nozzles 702 takes into account cleaning efficiency and cleaning effect, and they can spray the water pumped by the water pump at a certain pressure and angle. When the water pump starts and delivers water, the water flows through the water spraying pipe 701 to each water spraying nozzle 702, and then is sprayed in the form of high-speed, high-pressure water flow onto the surface to be cleaned. This spraying method not only effectively removes dirt and impurities on the surface, but also realizes comprehensive and uniform cleaning of different shapes and materials of the surface to be cleaned by adjusting the angle and number of the water spraying nozzles 702. The working principle of the water spraying device 7 embodies the concept of efficient and energy-saving cleaning. By precisely controlling the water pressure of the water pump and the design of the water spraying nozzles 702, the water spraying device 7 can maximize the saving of water resources and energy while ensuring the cleaning effect. In addition, the direction and angle of the water spraying nozzles 702 are adjustable, so that the water spraying device 7 can adapt to the needs of different cleaning scenes, improving the versatility and flexibility of the equipment.

[0034] The cleaning rolling device 9 is a key component in the semi-automatic mobile cleaning machine that realizes the cleaning function. The detailed structure and working principle bring technical effects, combined with the action of the support structure 6, which can be described as follows: the roller drive 901 as the power source of the cleaning rolling device 9, built-in high-efficiency drive motor. When the motor starts, it will provide sufficient rotary power for the roller drive 901, so that it can rotate smoothly and continuously. This rotating action is the basis for the work of the cleaning rolling device 9, which drives the porous nylon-silk rubber sheet 902 installed on the outer surface of the roller drive 901 to rotate together, thereby realizing the physical friction and cleaning effect on the surface to be cleaned. The porous nylon-silk rubber sheet 902 is the component of the cleaning rolling device 9 that directly contacts the surface to be cleaned. Its design takes into account both cleaning effect and protection of the surface to be cleaned. The porous structure allows the rubber sheet to better absorb and carry water during rotation, while the nylon silk enhances the cleaning ability and wear resistance of the rubber sheet. When the roller drive 901 rotates, these rubber sheets act like countless small brushes, constantly brushing the surface to be cleaned, effectively removing dirt and impurities. The upper connecting piece 903 tightly connects the cleaning rolling device 9 with the support structure 6. This design not only ensures the stability of the cleaning rolling device 9 during operation, but also makes the entire cleaning machine more compact and reasonable in structure. The support structure 6 provides the necessary support and fixation for the cleaning rolling device 9, so that the cleaning rolling device 9 can maintain a stable posture and high cleaning efficiency in various operating environments. The lower connecting plate 904 is fixed below the vehicle body base 101, providing another stable support point for the cleaning rolling device 9. This design further enhances the stability and reliability of the cleaning rolling device 9, so that it can always maintain a smooth rotation and cleaning action during operation.

[0035] The upper connecting piece (903) is provided with a long slot hole 907; the technical effects brought by this design, combined with the effect of the support structure 6, can be described as follows: enhance the cleaning effect: by adjusting the inclination angle of the roller drive 901 through the long slot hole 907, the rubber sheet 902 with multiple holes and nylon filaments can be more closely attached to the surface to be cleaned. The improvement of this degree of fit helps to enhance the cleaning effect, so that dirt and impurities are more easily removed. Adapt to different cleaning scenes: different cleaning scenes have different requirements for the cleaning rolling device 9. The design of the long slot hole 907 makes the roller drive 901 able to adjust the inclination angle according to the actual needs, so as to adapt to different cleaning surfaces and cleaning needs. This flexibility improves the versatility and practicality of the cleaning rolling device 9. Optimize the stress of the support structure: when the roller drive 901 is inclined forward, the support structure 6 needs to bear forces in different directions and sizes. Reasonable support structure design can ensure that these forces are effectively dispersed and transmitted, so as to avoid local stress concentration and structural damage. The design of the long slot hole 907 makes the inclination angle of the roller drive 901 adjustable, which helps to optimize the stress of the support structure and improve the stability and durability of the whole cleaning machine. Improve the operation convenience: the long slot hole 907 makes it easy for the operator to adjust the inclination angle of the roller drive 901, without the need for complex disassembly and reassembly work. This design improves the operation convenience of the cleaning machine, reduces the operation difficulty and time cost.

[0036] The rubber plate 905 and the stainless steel tray 906 installed on the bottom side of the porous rubber sheet with nylon filaments 902 are key designs to ensure safety and stable operation of the cleaning rolling device 9. The working principle of this design and the technical effects it brings can be elaborated as follows: Preventing nylon filaments from winding into gaps: During the rotation of the roller, the porous rubber sheet with nylon filaments 902 will continuously contact and rub against the surface to be cleaned. Without effective protection measures, nylon filaments may be wound into the gap between the roller and the vehicle base 101 due to friction or external forces, causing equipment damage or nylon filament breakage. The installation of the rubber plate 905 and the stainless steel tray 906 effectively prevents this from happening, as they form a physical barrier to ensure that nylon filaments do not wind into the gap. Protecting the roller and the base: The rubber plate 905 has good elasticity and wear resistance, and it can make slight contact with the vehicle base 101 during the rotation of the roller, thereby acting as a buffer and reducing wear. This helps to prolong the service life of the roller and the base, reducing wear and noise caused by friction. The stainless steel tray 906 provides more robust support and protection. Its rigidity and corrosion resistance ensure that nylon filaments do not directly contact the base, even in harsh cleaning environments, thereby avoiding equipment damage caused by corrosion or wear. Optimizing cleaning effect: The installation of the rubber plate 905 and the stainless steel tray 906 also helps to optimize the cleaning effect. They ensure that the porous rubber sheet with nylon filaments 902 can always maintain a stable position and will not be offset or deformed due to external forces. This allows nylon filaments to be more evenly distributed on the surface to be cleaned, improving the coverage and efficiency of cleaning. Enhancing the stability of the support structure: The rubber plate 905 and the stainless steel tray 906, as part of the cleaning rolling device 9, are closely connected with the support structure 6. Their presence enhances the overall stability of the support structure, allowing the roller to run more smoothly during rotation, reducing noise and wear caused by vibration or shaking.
