Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The experimental methods used in the following examples are conventional methods unless otherwise specified, and materials, reagents and the like used therein are commercially available without otherwise specified.

As described in the background art, most cleaning machine manufacturers use fixed liquid level switches, electrode type liquid level switches, tuning forks, capacitive liquid levels, and other detection methods in the conventional liquid storage tanks from the economic viewpoint. However, when the cleaning condition needs to be adjusted, the fixed liquid level switch needs to be opened again for fixing, the electrode type liquid level switch needs to replace electrode rods with different lengths, and the liquid levels such as a tuning fork type liquid level switch and a capacitance type liquid level switch also need to be opened again for installation, so that great inconvenience is brought.

In order to solve the problem, the utility model provides a liquid level detection device floats, including pole setting, hollow floater 3, floater fall tube 4, the liquid level detection pipe 5 and at least one inductive switch 7 float.

Referring to fig. 1, the front surface of the upright is provided with a sliding groove 10, and the back surface of the floating liquid level detecting tube 5 is fixedly provided with a sliding rail, so as to be slidably connected in the sliding groove 10. The top of the floating ball lifting pipe 4 is connected with the floating liquid level detection pipe 5, and the bottom is connected with the hollow floating ball 3. Preferably, the bottom of the vertical rod is fixed with a lifting pipe guide plate 2, a guide hole is formed in the lifting pipe guide plate 2, and the floating ball lifting pipe 4 penetrates through the guide hole. Thus, along with the lifting of the liquid level, the hollow floating ball 3 can drive the floating ball lifting pipe 4 and the floating liquid level detection pipe 5 to lift together. In the lifting process, the upper part is guided by the chute 10 of the upright rod, and the lower part is guided by the lifting pipe guide plate 2, so that the problem of unsmooth lifting is avoided. In this embodiment, common industry aluminium alloy 1 is selected for use to the pole setting, utilizes aluminium alloy 1 characteristics in recess all around, plugs into a slide rail in the recess, again in slide rail external connection liquid level detection pipe 5 can that floats.
