Problems solved by technology
At present, the gas nozzle and the air guide tube are connected by adhesive and fixed together with a pipe clip. The degree of fixation in this way depends on the quality and uniformity of the adhesive and the tightness of the pipe clip. This requires The workers who operate this process have reached a certain degree of proficiency in operation, so that the sealing quality of the gas nozzle and the air guide tube is closely related to the worker's operating level, making it difficult to control the quality of the seal after fixing
In addition, even if the adhesive has been applied evenly, it will still loosen due to uneven force during use, resulting in air leakage and affecting the detection accuracy of the water level sensor

Embodiment Construction
[0047] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0048] In the description of the present invention, the terms are first defined, the direction close to the axis is "inner", and the direction away from the axis is "outer". The terms are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying the device Or elements must have a certain orientation, be constructed and operate in a certain orientation, and thus should not be construed as limiting the invention.
[0049] refer to Figure 1-Figure 11 , is the first embodiment of a water level sensor proposed by the present invention. The water level sensor in this embodiment is used in a wash...

The invention provides a water level sensor, an assembling method and a washing machine. The water level sensor comprises a sensing head and a gas guide pipe. A gas nozzle is arranged on the sensing head and sleeved with one end of the gas guide pipe in a sealed mode. The water level sensor further comprises a slide ring used for fixing the gas guide pipe. The slide ring is arranged on a limiting structure and located on the outer side of the gas guide pipe. At least one inclined insertion part is arranged on the inner side of the slide ring. The insertion parts are inserted in the pipe wall of the gas guide pipe. The slide ring and the insertion parts are arranged, and therefore fixation between the slide ring and the gas guide pipe can be firm; in this way, even when the gas guide pipe unevenly bears force or bears axial tension in the sue process, the axial force borne by the gas guide pipe is transmitted to the slide ring through the insertion parts, looseness between the gas guide pipe and the gas nozzle is avoided, firmness and the sealing effect are ensured after the gas guide pipe is assembled, and the detection precision of the water level sensor is ensured.
Description
technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a water level sensor, an assembly method of the water level sensor, and a washing machine with the water level sensor. Background technique [0002] The washing machine is provided with a water level sensor for detecting the water level in the washing machine. The water level sensor has a sensing head and an air guide tube. The sensing head has an air nozzle, and one end of the air guide tube is sealed and sleeved on the air nozzle. At present, the gas nozzle and the air guide tube are connected by adhesive and fixed together with a pipe clip. The degree of fixation in this way depends on the quality and uniformity of the adhesive and the tightness of the pipe clip. This requires The workers who operate this process have reached a certain degree of proficiency in operation, so that the sealing quality of the gas nozzle and the air guide tube is closely relate...
