The utility model is further described below with reference to examples.

Examples: the floor washing machine is also called a floor washing machine and a floor washing and sucking machine, and is a cleaning machine for cleaning hard floor and sucking sewage at the same time and removing the sewage from the site.

Most of the floor washing machines suck sewage on the ground into the sewage tank under the action of the water sucking motor and the scraping belt water accumulation during use, and clean the sewage tank regularly, and most of the floor washing machines are small in volume and limited in water storage capacity, so that the sewage tank needs to be cleaned for many times.

The sewage storage box of the floor washing machine is provided, and according to the scheme, with reference to the accompanying drawings 1-7, the removed sewage can be automatically sucked into the sewage collection box 2 through pumping, pumping is stopped when a certain water level is reached, sewage overflow is avoided, and meanwhile, the disassembly and assembly structure between the whole sewage collection box 2 and the shell 1 is convenient, and the whole sewage storage box is convenient to use.

Specifically, this scheme mainly includes casing 1 and two parts of sewage collection box 2, and sewage collection box 2 demountable installation is on casing 1, and sewage collection box 2 comprises two demountable structures, including whole box body 23 and lid 24 that are rectangular form, the inside cavity of box body 23 and its upper end are equipped with the opening, lid 24 grafting cooperation is in the upper end opening part of box body 23, and the upper end of box body 23 is provided with protruding rail 231 along its circumference survey, lid 24 is provided with seal groove 241 towards the one end of box body 23 and corresponds the track that protruding rail 231 established, when the installation, aim at protruding rail 231 card with seal groove 241 and go into, the cross-section of protruding rail 231 in this scheme is isosceles trapezoid, thereby can provide better sealing environment when seal groove 241 is inlayed, avoid inside sewage to spill over.

And be equipped with two openings in the sewage collection box 2 in this scheme, two openings all communicate with each other with the external world, and arrange along sewage collection box 2 width direction respectively, be close to the side of box body 23 simultaneously, two openings are exhaust tube 21 and inlet tube 22 respectively, exhaust tube 21 passes through the negative pressure pipe and links to each other with the air pump, still be equipped with in the sewage collection box 2 with circuit breaker electric connection's water level monitor 3, water level monitor 3 is including two contacts 31, contact 31's height is less than the mouth of pipe height of exhaust tube 21, circuit breaker control opening and closing of air pump.

In the sewage discharging process, the air pump is started, the air in the box body 23 is pumped out through the negative pressure pipe, the pressure difference is formed between the inside and the outside of the box body 23, and under the negative pressure condition, sewage is sucked out and enters the box body 23 through the water inlet pipe 22.

When sewage is accumulated in the box body 23, the liquid level gradually rises, the water level monitor 3 arranged in the box body 23 senses the maximum water level, and the power supply of the air pump is disconnected through the circuit breaker electrically connected with the water level monitor, so that the air pump stops working, no negative pressure is generated in the box body 23, further the pumping of sewage is stopped, the sewage in the box body 23 cannot exceed the maximum water level, and accordingly overflow cannot occur.

And optionally, if in some full-automatic floor washing machines, still can let the circuit breaker establish with the drive structure that control floor washing machine marched and be connected, when the water level is at maximum, not only stop pumping sewage, whole floor washing machine stop work simultaneously, wait to clear up and carry out work again after the sewage collection box 2, specific electric connection technique is common sense, and this scheme does not have too much description, also does not show air pump, drive structure etc. in the figure.

The monitoring liquid level is two needle-shaped contacts 31 in this scheme to all set up with box body 23 is perpendicular, and contact 31's top can electrically conduct, when the liquid level had fallen beyond contact 31 top, produces little electric current, is connected with the circuit breaker this moment, and the circuit breaker begins work after receiving the outage signal, makes the air pump stop pumping, and in order to guarantee that inlet tube 22 can not produce recoil phenomenon, sewage can suck back in inlet tube 22 promptly, especially keeps the same with inlet tube 22 orificial height with contact 31's top height, and both highly are less than the orificial height of exhaust tube 21, even if reach the maximum liquid level, also can not let exhaust tube 21 take away sewage in the box body 23 and cause the jam.

In order to further avoid that the air exhaust pipe 21 cannot suck water in during operation, one end of the box cover 24 facing the box body 23 is provided with a conical cavity 243, during operation, the conical cavity 243 is sleeved at the upper end of the air exhaust pipe 21 to prevent splashed water from being sucked away, one end of the box cover 24 facing the box body 23 is provided with two baffle plates 242 which are perpendicular to each other, two end surfaces of the two baffle plates 242 and the box body 23 form a rectangular enclosing space, the air exhaust pipe 21 is positioned in the enclosing space, the distance between one end of the two baffle plates 242 facing the box body 23 and the bottom end of the box body 23 is smaller than the distance between the pipe orifice of the water inlet pipe 22 and the bottom end of the box body 23, and further protection is formed on the periphery of the air exhaust pipe 21, and splashed water can be blocked when water flow is large.

Meanwhile, the pipe opening of the water inlet pipe 22 is vertically provided with a guide pipe 221, the guide pipe 221 extends towards the side far away from the exhaust pipe 21, and the water inlet is arranged far away from the exhaust pipe 21, so that the possibility that splashed water liquid enters the vicinity of the exhaust pipe 21 is further reduced.

And adopt buckle formula fixed design between box body 23 and the casing 1 in this scheme, specific two sides that are located box body 23 have offered respectively and have been dodged hole 232, dodge hole 232 and the inside communication of box body 23, and be located casing 1 on elastic hinge have a lug 11, the upper end of lug 11 be the inclined plane and with dodge hole 232 dislocation set to can dodge hole 232 internal rotation and dodge hole 232 looks block when contacting and dodge hole 232.

The other side of the protruding block 11 is exposed at the outer side end of the shell 1, when the box 23 needs to be detached, the protruding block 11 is pressed at the position of the outer side end of the shell 1, at the moment, the protruding block 11 starts to rotate, and one side of the protruding block 11 clamped into the avoiding hole 232 can be tilted to separate from the avoiding hole 232, so that the box 23 can be detached.

The elastic member for elastically rotating the bump 11 is not particularly limited, and may be a torsion spring, etc., in this case, a spring 111 is disposed between the housing 1 and a side of the bump 11 away from the avoiding hole 231 to provide resistance when the bump 11 rotates.

The above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; these modifications or substitutions do not depart from the essence of the corresponding technical solutions from the protection scope of the technical solutions of the embodiments of the present utility model.
