Technical Field

[0001] The utility model relates to the field of cleaning equipment, and particularly relates to a liquid level detection structure applied to a sewage tank of a cleaning equipment. Background Art

[0002] A sewage tank is usually arranged in a cleaning equipment. In order to avoid the sewage tank from overflowing due to excessive sewage, a liquid level sensor is currently arranged in the sewage tank to detect the liquid level state. Since the cleaning equipment needs to move continuously during use, the sewage in the sewage tank is easy to splash onto the liquid level sensor and send out false signals, seriously affecting the use experience.

[0003] Therefore, aiming at the deficiencies of the existing technology, it is necessary to design a liquid level detection structure applied to a sewage tank of a cleaning equipment to solve the above problems. Summary of the Utility Model

[0004] In order to overcome the above deficiencies in the existing technology, the purpose of the utility model is to provide a liquid level detection structure applied to a sewage tank of a cleaning equipment.

[0005] In order to achieve the above purpose and other related purposes, the technical solution provided by the utility model is: a liquid level detection structure applied to a sewage tank of a cleaning equipment, including a sewage tank, a tank cover is provided at the top opening of the sewage tank, a liquid level sensor is fixedly provided on the bottom side of the tank cover, the detection end of the liquid level sensor is configured as a rod-shaped structure and is sleeved with a splash-proof sleeve, and a detection window is opened on the bottom side of the splash-proof sleeve.

[0006] The preferred technical solution is: a buckling point is provided on the detection end of the liquid level sensor, and a buckling hole corresponding to and matching the buckling point is provided on the splash-proof sleeve.

[0007] The preferred technical solution is: the inner diameter of the splash-proof sleeve is larger than the outer diameter of the detection end of the liquid level sensor.

[0008] The preferred technical solution is: a sealing ring is sleeved on the outer periphery of the tank cover, and the tank cover and the sewage tank are hermetically connected through the sealing ring.

[0009] The preferred technical solution is: a HEPA installation groove is provided on the top side of the tank cover, the bottom of the HEPA installation groove is communicated with the bottom of the tank cover, and a HEPA is detachably installed in the HEPA installation groove.

[0010] The preferred technical solution is: a cover-shaped structure with a side opening is provided at the bottom of the tank cover, and the cover-shaped structure is correspondingly arranged with the bottom of the HEPA installation groove.

[0011] Due to the application of the above technical solution, the beneficial effects of the utility model are:

[0012] The liquid level detection structure applied to the sewage tank of the cleaning equipment proposed by the present utility model solves the problem that the sewage frequently splashes on the detection end of the liquid level sensor and emits false signals. By sleeving a splash-proof sleeve on the detection end of the liquid level sensor and opening a detection window on the bottom side of the splash-proof sleeve, the liquid level sensor in the splash-proof sleeve will only emit a detection signal when the liquid level exceeds the detection window. The structure is ingenious, simple to assemble, and suitable for popularization. Brief Description of the Drawings
