Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Please see Figures 1-6 A liquid flow sensing device for a self-service car wash machine includes a sensor body 1, with clamping devices 2 clamped on both sides of the sensor body 1. A balance component 3, a mounting component 4, and two fixing components 5 are sequentially arranged at the bottom of the two clamping devices 2. The sensor body 1 and the balance component 3 always remain parallel.

[0032] The bottom surfaces of the two clamping devices 2 are fixed to the top surface of the balancer 3 and are located on both sides of the balancer 3. There is a gap between the bottom surface of the balancer 3 and the top surface of the mounting part 4 and they are rotatably connected. The two fixing parts 5 penetrate the mounting part 4 vertically and their upper ends are in contact with the bottom surface of the balancer 3. The two fixing parts 5 are located on different sides of the rotation axis of the balancer 3 and the mounting part 4, respectively.

[0033] A torque spring 6 is provided at the point where the balancing component 3 and the mounting component 4 rotate. When the balancing component 3 and the fixing component 5 are parallel, the torque spring 6 has no torque force.

[0034] It should be noted that when the sensor body 1 is not kept horizontal, the device can adjust the angle between the balance component 3 and the mounting component 4 by rotating the fixing parts 5 on both sides, thereby adjusting the sensor body 1 so that the sensor body 1 is kept horizontal, ensuring the measurement accuracy of the sensor body 1 for liquids, and improving car washing efficiency and safety.

[0035] In this embodiment, the balancing component 3 includes a balancing plate 31, a protrusion 32 is provided at the bottom center of the balancing plate 31, and pins 33 are provided at both ends of the protrusion 32. The mounting component 4 includes a convex plate 41, and end blocks 42 are provided on both the front and rear sides of the upper center of the convex plate 41. The pins 33 on the same side are inserted into the end blocks 42.

[0036] It should be noted that the plug-in cooperation between the protrusion 32 in the balancing piece 3 and the end block 42 in the mounting piece 4 not only realizes the preliminary positioning between the balancing piece 3 and the mounting piece 4, but also facilitates the subsequent installation and debugging of the torque spring 6. This plug-in design makes the device more convenient and fast during assembly, while ensuring the stability of the connection.

[0037] In this embodiment, the sliding grooves 34 are arranged on both sides of the bottom of the balancing plate 31, and the spherical end 52 is arranged on the side of the fixing piece 5 close to the balancing piece 3, and the outer surface of the spherical end 52 is in contact with the sliding grooves 34.

[0038] It should be noted that the sliding grooves 34 on the bottom of the balancing plate 31 and the spherical end 52 on the fixing piece 5 cooperate with each other to form an adjustable support structure. When the fixing piece 5 is tightened by the bolt structure, the spherical end 52 will slide in the sliding groove 34 and find the best support point, thereby ensuring the stable rotation of the balancing piece 3 on the mounting piece 4. This design improves the adaptability and stability of the device.

[0039] In this embodiment, each latch 33 is plugged with a torque spring 6, and the torque spring 6 is located between the end block 42 and the protrusion 32.

[0040] It should be noted that the torque spring 6 is provided to provide a certain pre-tightening force between the balancing piece 3 and the fixing piece 5. When the balancing piece 3 is tilted, the torque spring 6 will generate a restoring torque to make the balancing piece 3 and the fixing piece 5 in close contact. This design improves the matching strength of the device, making the sensor body 1 work more stably.

[0041] In this embodiment, the convex plate 41 is provided with a plurality of mounting holes 43 for fixing the mounting piece 4 on both sides.

[0042] It should be noted that the mounting holes 43 facilitate the subsequent fixing and installation of the mounting piece 4 by screws and other fixing components.

[0043] In this embodiment, the fixing piece 5 is a bolt structure, and a circle of anti-skid strips 51 is arranged on the end away from the balancing piece 3.

[0044] It should be noted that the anti-skid strips 51 can improve the friction between the hands and the fixing piece 5, facilitate the rotation of the fixing piece 5, and save the labor of adjusting the sensor body 1 horizontally.

[0045] In this embodiment, the balancing piece 3 is provided with a level 7 parallel to the sensor body 1 on the upper surface.

[0046] It should be noted that the level 7 on the upper surface of the balancing piece 3 is used to monitor the tilting state of the balancing piece 3 in real time, and when the balancing piece 3 tilts, it can be found and corrected in time through the level 7. This design makes the device more convenient and reliable during installation and use.

[0047] In this embodiment, the sensor body 1 is provided with a pipe 8 at both ends, and the two pipes 8 are located outside the two clamping devices 2, and the axis of the pipe 8 and the clamping axis of the clamping device 2 are collinear.

[0048] It should be noted that the pipe 8 axis and the clamping axis of the clamping device 2 are collinear, which not only ensures the connection stability and sealing between the pipe 8 and the sensor body 1, but also reduces the vibration and interference of the pipe 8 during car washing. This design improves the durability and car washing effect of the device.

[0049] In summary: Compared with the unadjustable levelness of the liquid flow sensing device of the traditional self-service car washing machine, the self-service car washing machine liquid flow sensing device, through the combination of the mounting part 4 and the balancing part 3, and with the assistance of the two fixing parts 5, ensures that the sensor body 1 always maintains a horizontal state during installation and use. Specifically, the balancing part 3 and the mounting part 4 are connected in a rotating manner, and are provided with a torque spring 6, the fixing part 5 penetrates the mounting part 4 vertically and contacts the bottom surface of the balancing part 3, and through the rotation difference of the two fixing parts 5, the included angle between the balancing part 3 and the mounting part 4 can be changed, so as to adjust the horizontal state of the sensor body 1, to meet the needs of different use scenarios. When the car washing machine is used on different slope ground, the balancing part 3 can be quickly adjusted to the best position by rotating the fixing part 5, to ensure the levelness of the sensor body 1, and then to ensure the accurate measurement of the liquid flow.

[0050] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
