Description

Technical Field

[0001] This utility model relates to the field of water level detection technology, specifically to a sewage tank and a floor scrubbing machine. Background Technology

[0002] Most existing floor cleaning equipment is equipped with a set of vertical columnar electrodes. During the wastewater recycling process, depending on the needs and usage habits of different users, the body of the floor scrubber may rotate left and right around its own axis to increase the cleaning range. At this time, the wastewater will concentrate on one side of the wastewater tank, and the wastewater may only be in contact with one electrode, which will prevent the water full alarm from being triggered. In severe cases, it may damage the vacuum motor. Utility Model Content

[0003] The purpose of this invention is to provide a sewage tank to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a sewage tank, comprising a tank body, a tank cover, and a liquid level detection component. The liquid level detection component is disposed on the tank body and / or the tank cover and is used to detect the water level inside the tank. The liquid level detection component includes a first electrode and a second electrode, the first electrode and the second electrode having opposite polarities. The first electrode extends downward along the length direction of the tank body, and the end of the first electrode is set in an arc shape along the circumference of the tank body.

[0005] The end of the first electrode is arranged in a circular shape along the circumference of the box.

[0006] The end of the first electrode is set in a semi-circular shape along the circumference of the box.

[0007] The second electrode extends downward along the length of the box, and the end of the first electrode and the end of the second electrode are at the same height.

[0008] The second electrode extends downward along the length of the housing, and the end of the second electrode is located below the end of the first electrode.

[0009] The second electrode is located at the bottom of the housing.

[0010] The second electrode is located in the middle of the housing and is equidistant from the arc-shaped end of the first electrode.

[0011] The second objective of this utility model is to provide a floor scrubbing machine, including a machine body and a wastewater tank detachably connected to the machine body, wherein the wastewater tank is the wastewater tank as described above.

[0012] Compared with the prior art, the beneficial effects of this utility model are: by setting the first electrode with an arc-shaped end, the liquid level detection component can still operate sensitively during the left and right rotation and tilting operation of the floor scrubber, avoiding the situation where sewage concentrates on one side of the sewage tank and sewage can only contact one electrode, thereby effectively protecting the vacuum motor and maintaining the normal operation of the floor scrubber.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1:

[0019] Please see Figures 1-3The present invention provides the following technical solution: a sewage tank 100, characterized in that it includes a tank body 110, a tank cover 120, and a liquid level detection component 130. The liquid level detection component 130 is disposed on the tank cover 120 and is used to detect the water level in the tank body 110. The liquid level detection component 130 includes a first electrode 131 and a second electrode 132. The first electrode 131 and the second electrode 132 have opposite polarities. The first electrode 131 extends downward along the length direction of the tank body 110, and the end 1311 of the first electrode 131 is set in an arc shape along the circumference of the tank body 110. This allows the sewage tank 100 to rotate left and right or tilt during operation, so that no matter which side the sewage is concentrated on, the sewage can contact the first electrode 131 and the second electrode 132. This makes the liquid level detection component 130 operate sensitively and avoids the situation where the sewage can only contact one electrode when it is concentrated on one side of the sewage tank 100. This effectively protects the vacuum motor and maintains the normal operation of the floor scrubber. In other embodiments, the liquid level detection component 130 may be disposed on the housing 110, and there is no limitation on this.

[0020] In one embodiment, the end 1311 of the first electrode 131 is arranged in a ring shape along the circumference of the housing 110. The ring shape provides a higher accuracy for liquid level detection compared to the arc shape.

[0021] In another embodiment, the end 1311 of the first electrode 131 is configured as a semi-circular ring along the circumference of the housing 110. The semi-circular ring shape is less expensive than a circular ring shape, while still maintaining the accuracy of liquid level detection. This invention does not limit the specific arc shape of the end 1311 of the first electrode 131.

[0022] The second electrode 132 extends downward along the length of the tank 110, and the end 1311 of the first electrode 131 and the end of the second electrode 132 are at the same height. If the end of the second electrode 132 is located further away from the bottom of the tank 110, even if the first electrode 131 is in contact with the sewage, the second electrode 132 cannot be in contact with the sewage, and the two electrodes cannot be connected, so accurate liquid level detection cannot be performed.

[0023] In another embodiment, the second electrode 132 is located in the middle of the tank 110, extending downwards along the length of the tank 110, with its end below the end 1311 of the first electrode 131. Based on the previous embodiment, since the second electrode 132 is located in the middle of the tank 110, rather than on its side, when the tank 110 is tilted to one side, there may be a situation where only the first electrode 131 is in contact, but the electrode 132 is not. In this case, setting the end of the second electrode 132 below the end 1311 of the first electrode 131 ensures that both the end of the second electrode 132 and the end 1311 of the first electrode 131 can simultaneously contact the wastewater, guaranteeing the accuracy of the liquid level detection.

[0024] In yet another implementation, such as Figure 2 As shown, the second electrode 132 is located at the bottom of the tank 110. Once the sewage comes into contact with the first electrode 131, the two electrodes can be connected, making the liquid level detection more accurate.

[0025] In one embodiment, the second electrode 132 is located in the middle of the tank 110, and the distance between the second electrode 132 and the arcuate end 1311 of the first electrode 131 is equal at all points. This avoids the situation where the second electrode 132 is located on the left side of the tank 110, and the sewage tank 100 is tilted to the right, preventing the sewage from simultaneously contacting the first electrode 131 and the second electrode 132, which would lead to inaccurate liquid level detection. In other embodiments, the distance between the second electrode 132 and the arcuate end 1311 of the first electrode 131 can vary slightly and does not need to be completely equal; the ratio between the closest and furthest distances should be less than 2.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
