Description

Technical Field

[0001] The present invention relates to the technical field of floor scrubbers, and in particular to a sewage discharge mechanism and a floor scrubber. Background Art

[0002] The main components of a floor scrubber can be divided into a floor brush, sewage tank, clean water tank, main unit, and handle. The working principle is that the water pump pumps the water in the clean water tank to spray it onto the roller brush to wet the roller brush, and the roller brush rotates to achieve a cleaning effect. The vacuum motor in the main unit generates suction, and the sewage is sucked into the pipe through the suction port on the floor brush and sent to the sewage tank. The handle assembly plays a role in control and human-machine interaction.

[0003] A fully automatic base station can be used to automatically clean the sewage tank. During the sewage discharge process of a floor scrubber with a base station, after the entire machine is placed in the base station, the sewage tank needs to open and close the lid automatically. Generally, the automatic opening method of the sewage tank is to flip the lid 90 degrees around the axis. After the lid is opened, a part of the lid is still under the sewage outlet. Therefore, during the sewage discharge process, the lid will be stained with sewage, causing unnecessary pollution.

[0004] The main reason is that after the sealing cover of the sewage tank of the floor scrubber is flipped, part of it is still under the projection surface of the sewage outlet; or, the flip angle of the sealing flap is not enough and can only be flipped 90 degrees, causing the sealing cover of the sewage tank to still be under the sewage outlet.

[0104] When the movable part 20 is in the open state, the preset opening 21 is located in the sewage channel, so that the sewage channel is in a connected state through the preset opening 21; that is, at this time, the preset opening 21 is located between the first end and the second end of the sewage channel, so that the first end and the second end of the sewage channel are connected through the preset opening 21; at this time, the sewage flowing into the sewage channel from the first end of the sewage channel can flow to the second end of the sewage channel through the preset opening 21, and then flow out from the second end of the sewage channel.

[0105] When the movable part 20 is in a closed state, the main body of the movable part 20 is stopped in the sewage channel, so that the sewage channel is in a disconnected state; that is, at this time, the main body of the movable part 20 is located between the first end and the second end of the sewage channel, and the main body of the movable part 20 is stopped between the first end and the second end of the sewage channel, so that the first end and the second end of the sewage channel through the main body of the movable part 20 is in a disconnected state; at this time, the sewage flowing into the sewage channel from the first end of the sewage channel cannot flow to the second end of the sewage channel.

[0106] The sewage discharge mechanism of the present application solves the problem in the prior art that the cover of the floor scrubber will be stained with sewage during the sewage discharge process.

[0107] The sewage discharge mechanism of the present application has the following characteristics: 1. The entire moving structure has few parts and the movement process is simple; 2. It is fully automatic to open and close and easy to operate; 3. The overall structure is simple and effective.

[0108] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0109] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0110] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
