Detailed Description

The present invention will be further explained with reference to the drawings and examples.

This embodiment is improved for a scrubber sewage tank.

Referring to fig. 2 and 3, the sump 10 of the floor washing machine includes a tank body 11, a float 12, and a rubber pad 13. The bottom of the box body 11 is provided with a sewage inlet 16 extending towards the inside of the box body 11, the top of the box body 11 is provided with an air suction opening 15, and the inside of the box body 11 is provided with a support 14 corresponding to the air suction opening 15; the float 12 is arranged in the box body 11, and the float 12 is in sliding fit with the bracket 14 and can move towards the pumping hole 15 under the buoyancy action of liquid; the rubber pad 13 is disposed on the top of the float 12, and is used for sealing the air suction port 15.

In this embodiment, a positioning portion is provided on the top of the float 12, and the positioning portion is used to align the rubber pad 13 with the top of the float 12 when the rubber pad 13 is assembled. With further reference to fig. 2, fig. 3, fig. 4, fig. 6, fig. 7, and fig. 8, in this embodiment, the positioning portion is specifically an upward protrusion 122 on the periphery of the float 12, the protrusion 122 is specifically an annular protruding strip, and the height of the protrusion 122 is smaller than the height of the rubber mat 13. During installation, the rubber pad 13 is embedded in the annular convex strip and bonded with the top of the floater 12. Can conveniently, and accurately install cushion 13 in the top of float 12 like this, avoid cushion 13 to glue the phenomenon partially to can guarantee float 12's uniformity and outward appearance. Because the rubber mat 13 is not adhered to the upper limit position, the air suction port 15 (see fig. 5) can be reliably sealed when the floater 12 is at the upper limit position, so that a negative pressure channel can be reliably blocked, and therefore, the reliability of the floater 12 for sealing the air suction port 15 is improved by adding the positioning part of the rubber mat 13 at the top end of the floater 12, the stability of the performance of the whole machine can be improved, and the satisfaction degree of a user can be improved. In addition, the convex strips surround the rubber mat 13, so that the rubber mat 13 is protected, the rubber mat 13 is not easily scratched by the bracket 14 and is not tilted in the movement of the floater 12, and the service life is prolonged.

In light of the above embodiments, it will be understood by those skilled in the art that the rubber pad 13 can be precisely positioned and protected by intermittently providing a plurality of protrusions on the top of the float 12. Furthermore, a protrusion may be provided at other locations (e.g., the center) on the top of the float 12 to provide a positioning function for the rubber pad 13.

With further reference to fig. 2 and 7, two opposite side portions of the float 12 are respectively provided with a sliding block 121, the bracket 14 is provided with a sliding groove 141 corresponding to the sliding block 121, and the sliding block 121 is in sliding fit with the sliding groove 141 to form a guiding mechanism of the float 12. The guide mechanism guides the float 12 to move downwards or upwards, and can improve the reliability of the float 12 in controlling the opening/closing of the air suction opening 15.

The float 12 is a hollow plastic piece in the shape of a cuboid, which can be made by a blow molding process.

The working principle of the sewage tank 10 of the local machine is as follows: during operation, a negative pressure is formed in the box body 11 through the air suction port 15, the flow direction of water vapor is shown by an arrow D in fig. 3, water stains and garbage are sucked into the box body 11 from the sewage inlet 16 through the negative pressure, the floater 12 gradually rises along with the rise of the sewage water level, when the floater 12 rises to the upper limit position, as shown in fig. 4 and 5, the air suction port 15 is sealed through the rubber cushion 13 on the top of the floater 12, on one hand, a negative pressure channel is blocked, so that the water stains and the garbage can not be sucked, on the other hand, the pressure at the end of the air suction port 15 changes, and the pressure sensor detects the pressure change, so that the automatic detection of whether the sewage tank 10 is full of sewage can be realized.

Fig. 9 shows a floor washing machine comprising a body assembly 50, a cleaning head assembly 20 hinged to the bottom end of the body assembly 50, a handle assembly 60 disposed at the top end of the body assembly 50, a clean water tank 40 and a waste water tank 10 detachably mounted to the body, and a charging base 30. The waste water tank 10 is the waste water tank 10 of the above embodiment.

Therefore, the positioning part is added on the top end of the floater 12 of the floor washing machine sewage tank 10 in the embodiment, and on one hand, the positioning part plays a role in positioning the rubber mat 13 to ensure that the assembling position of the rubber mat 13 is accurate, so that the reliability of the floater 12 for sealing the air suction opening 15 is improved, the performance stability of the whole machine can be improved, and the satisfaction degree of a user can be improved; on the other hand, the positioning part plays a role in protecting the rubber mat 13, prevents the edge of the rubber mat 13 from tilting, and prolongs the service life.

The present invention has been described in detail with reference to the specific embodiments, and the detailed description is only for assisting the skilled person in understanding the content of the present invention, and can not be understood as the limitation of the protection scope of the present invention. Various decorations, equivalent changes and the like which are performed on the scheme by the technical personnel in the field under the conception of the invention are all included in the protection scope of the invention.
