Description

Technical Field

[0001] The utility model relates to the technical field of disinfection equipment, in particular to a liquid level detection system for disinfection equipment. Background Art

[0002] Disinfection refers to a method that kills pathogenic microorganisms, but not necessarily bacterial spores. Chemical methods are usually used to achieve the effect of disinfection. Chemical drugs used for disinfection are called disinfectants. Sterilization refers to a method that kills all microorganisms (including bacterial spores) on an object. Physical methods are usually used to achieve the purpose of sterilization.

[0003] The Chinese utility model patent with application number: 202010271462.2 discloses a disinfection robot and a disinfection method for the disinfection robot. However, this type of disinfection robot does not have a liquid level detection device, that is, it is unable to detect the remaining amount of disinfectant in the disinfection box, and manual detection of the disinfectant is required. Since the disinfectant will corrode the liquid level sensor, the existing liquid level sensor cannot be used in the liquid level detection device of this type of disinfection robot. In addition, since the disinfection robot will move during the disinfection process, the disinfectant inside the disinfection box will fluctuate with the movement of the robot, resulting in low accuracy and large errors in the liquid level detection device. Most liquid level detection devices are arranged at a single point, resulting in low accuracy in the detection result, which is not suitable for disinfection robots that need to perform mobile operations.

[0004] After searching the existing Chinese patents: a liquid level detection device for disinfection equipment (Announcement No.: CN216283802U), including an atomizer box assembly, the interior of the atomizer box assembly is a hollow structure, and also includes a support assembly, a liquid level detection assembly, a wave-proof assembly and a mounting assembly. The support assembly is located inside the atomizer box assembly, the liquid level detection assembly is located at the bottom of the support assembly, the wave-proof assembly is located at the bottom of the inner side of the support assembly and is located on the outside of the liquid level detection assembly, and the mounting assembly is located on the upper part of the support assembly. The beneficial effect of the utility model is that a support assembly is provided to avoid contact between the liquid level sensor and the liquid, and to prevent the disinfection liquid from corroding the sensor, thereby causing inaccurate liquid level detection. A liquid level detection assembly is provided to perform liquid level detection through a multi-point layout structure to ensure high detection accuracy and small detection error. A wave-proof assembly is provided to reduce the fluctuation of the liquid inside the equipment when it moves, thereby improving the accuracy of liquid level detection. An mounting assembly is provided to stably connect the equipment to the disinfection equipment.

[0005] Although the above patent sets a sensor receiving block so that a liquid level sensor is fixed inside the sensor receiving block, thereby avoiding contact between the liquid level sensor and the liquid and preventing the disinfectant liquid from corroding the sensor, there is a disadvantage that the sensor receiving block on which the liquid level sensor is fixed is fixedly connected to the atomizer box base. In this way, when the liquid level sensor in the sensor receiving block fails or malfunctions, the sensor receiving block cannot be easily replaced from the atomizer box base, and the installation is also very inconvenient.

[0006] Therefore, it is necessary to invent a liquid level detection system for disinfection equipment to solve the above problems. Utility Model Content
