As shown in fig. 3 to 9, the sump 200 includes a tank body 1, a float block 2, a magnetic member 3, and a hall switch 4. A sewage cavity 10 is defined in the box body 1, the box body 1 is provided with a water inlet 11, and sewage enters the sewage cavity 10 through the water inlet 11 to be stored. The floating block 2 is floatably disposed in the sewage chamber 10 in a vertical direction, that is, the floating block 2 may rise or fall with the sewage level in the sewage tank 200.

One of the magnetic part 3 and the Hall switch 4 is arranged on the floating block 2, the other one of the magnetic part 3 and the Hall switch 4 is fixed with the relative position of the box body 1, when the floating block 2 reaches the upper limit position under the action of buoyancy, the magnetic part 3 triggers the Hall switch 4, the Hall switch 4 generates a sensing signal, and the sensing signal is used for giving a prompt or powering off the cleaning device.

The embodiment of the utility model provides a cleaning device's sewage case has sewage water level detection function, through set up floatable floating block in the box, make floating block drive magnetic part or hall switch along with rising or reducing of sewage intracavity sewage water level and fluctuate, thereby when sewage capacity reaches the upper limit, the floating block reachs extreme position, magnetic part triggers hall switch, send prompt signal or with cleaning device outage stop work, with the suggestion user pour the sewage of sewage incasement, avoid because sewage is excessive to lead to cleaning device to damage or clean the effect not good, the detection effect of sewage case is reliable, moreover, the steam generator is simple in structure, the cost is lower.

In some embodiments, as shown in fig. 4, the magnetic member 3 is provided on the floating block 2, and the hall switch 4 is provided outside the housing 1, and when the floating block 2 reaches the upper limit position, the magnetic member 3 is horizontally opposed to the hall switch 4, and when the magnetic member 3 is horizontally opposed to the hall switch 4, the magnetic member 3 activates the hall switch 4.

In other embodiments, the hall switch 4 may also be disposed on the floating block 2, the magnetic member 3 is disposed at a corresponding position of the case 1, when the floating block 2 reaches the upper limit position, the magnetic member 3 is opposite to the hall switch 4 in the horizontal direction, and when the magnetic member 3 is opposite to the hall switch 4 in the horizontal direction, the magnetic member 3 triggers the hall switch 4.

Since the hall switch 4 needs to be connected to a circuit, it is preferable to adopt a scheme in which the magnetic member 3 is provided on the floating block 2 and the hall switch 4 is provided outside the case 1.

Further, as shown in fig. 6, the floating block 2 includes a housing 21, the housing 21 has a sealed cavity 211 therein, and the magnetic member 3 is provided in the sealed cavity 211 and is disposed adjacent to the hall switch 4 in the horizontal direction. That is, the magnetic member 3 is provided inside the floating block 2, and in order to make the trigger effect more sensitive, the magnetic member 3 is provided close to the hall switch 4 in the sealed chamber. As an example, as shown in fig. 4 and 6, the magnetic member 3 may abut against an inner wall surface of the housing 21 close to the side wall of the hall switch 4.

In some embodiments, the tank 1 includes a body 12 and a tank cover 13, and the tank cover 13 is connected to a top of the body 12 and defines the sewage chamber 10 together with the body 12.

Specifically, as shown in fig. 6, the cover 13 is fastened to the top of the body 12. The box cover 13 is provided with an air suction opening 131, the air suction opening 131 is used for sucking air to enable sewage to enter the sewage cavity 10 from the water inlet 11, the air suction opening 131 can be connected with a suction assembly 130 (such as a vacuum pump), and negative pressure can be formed in the sewage cavity 10 by sucking air from the air suction opening 131. The bottom of the body 12 has a water inlet 121, a water inlet pipe 14 extending in a vertical direction is provided in the body 12, the bottom of the water inlet pipe 14 is communicated with the water inlet 121, the top of the water inlet pipe 14 is communicated with the water inlet 11, or the top of the water inlet pipe 14 is configured as the water inlet 11 of the tank 1. In the embodiment shown in fig. 6, the water inlet 121 is disposed at the middle of the bottom of the body 12, the water inlet pipe 14 is disposed at the middle of the body 12, and only the bottom of the water inlet pipe 14 is connected to the body 12. It will be appreciated that the height of the inlet pipe 14 is related to the maximum limit level of the waste water tank 200, and the maximum limit level of the waste water tank 200 should be lower than the top of the inlet pipe 14, i.e. lower than the inlet 11, otherwise the waste water in the waste water tank 200 will flow backward from the inlet 11 and affect the cleaning effect.

The suction assembly 130 is connected to the suction opening 131 to suck air through the suction opening 131, so that a negative pressure is formed in the sewage chamber 10, and the air drives the sewage to flow into the water inlet pipe 14 from the water inlet 121 together, and flow upward along the water inlet pipe 14, and flow into the sewage chamber 10 from the top of the water inlet pipe 14, that is, from the water inlet 11. Subsequently, the sewage remains in the sewage chamber 10 due to gravity, and the air is drawn out from the suction opening 131. The liquid level in the sewage chamber 10 gradually rises along with the increase of the volume of the sewage, and drives the floating block 2 to gradually move upwards.

Further, when the floating block 2 reaches the upper limit position, the top of the floating block 2 blocks the pumping port 131. That is, when the sewage in the sewage tank 200 reaches the maximum capacity, the top of the floating block 2 can block the suction opening 131, so as to avoid the damage of the equipment caused by the sewage being drawn into the pump through the suction opening 131 by the negative pressure at the suction opening 131. As shown in fig. 6, the top of the float 2 closes the suction opening 131.

In order to limit the moving path of the slider 2. In some embodiments, the cabinet 1 includes a guide case 132, the guide case 132 is connected to the bottom of the cabinet cover 13 and extends downward in a vertical direction from the bottom of the cabinet cover 13, and at least a portion of the floating block 2 is fitted in the guide case 132 and slidably disposed in the vertical direction along the guide case 132. That is to say, in the process that the floating block 2 floats up and down in the vertical direction, at least one part of the floating block is located in the guide shell 132, and the guide shell 132 limits the moving direction of the floating block 2, so that the phenomenon that the magnetic part 3 in the floating block 2 cannot trigger the hall switch 4 due to deflection, turnover and the like of the floating block 2 during floating is avoided.

In the embodiment shown in fig. 8, the guide housing 132 is injection molded integrally with the cover 13. The guide housing 132 includes first and second opposite side walls 1321 and 1322 extending in a vertical direction, and the floating block 2 is located between the first and second side walls 1321 and 1322.

Further, one of the guide shell 132 and the floating block 2 is provided with a guide groove 133 extending in the vertical direction, and the other of the guide shell 132 and the floating block 2 is provided with a guide block 22, and the guide block 22 is fitted in the guide groove 133 and slidably disposed along the guide groove 133. In the embodiment shown in fig. 8, the first side wall 1321 and the second side wall 1322 of the guide shell 132 are each provided with a guide groove 133 therethrough. A portion of an outer wall surface of the floating block 2 opposite to the first side wall 1321 and the second side wall 1322 is outwardly protruded to form a guide block 22, and the guide block 22 is fitted in the corresponding guide groove 133.

As shown in fig. 7, the number of the guide blocks 22 fitted in the guide grooves 133 on the first side wall 1321 is two, and the two guide blocks 22 are arranged at a spacing in the vertical direction. The guide groove 133 has a top wall surface and a bottom wall surface opposed to each other in the vertical direction. In the upper limit position, the upper guide block 22 can abut against the top wall surface of the guide groove 133, and in the lower limit position, the lower guide block 22 can abut against the bottom wall surface of the guide groove 133. A part of the first side wall 1321 protrudes into the guide groove 133 to form a protrusion 134, and the protrusion 134 is located between the top wall surface and the bottom wall surface of the guide groove 133 in the vertical direction. When the floating block 2 is located at the upper limit position, both the guide blocks 22 are located above the protrusion 134, and when the floating block 2 is located at the lower limit position, the protrusion 134 is located between the two guide blocks 22, i.e., the lower guide block 22 is located below the protrusion 134, and the upper guide block 22 is located above the protrusion 134. The protrusion 134 prevents the floating block 2 from being sucked to the upper limit position by the pumping pressure when the water level in the soil chamber 10 is low, thereby causing a false alarm of the full state of the soil tank 200. Specifically, when the water level in the sewage chamber 10 is low, the lower guide block 22 is located below the protrusion 134, and if the floating block 2 is attracted by the suction force to move upwards, the lower guide block 22 abuts against the protrusion 134, so that the magnetic member 3 is prevented from triggering the hall switch 4 when the floating block 2 is attracted to the upper limit position, and a misjudgment signal is sent out. It should be noted that, when the floating block 2 moves upward under the action of normal floating force, the guide block 22 can slide upward from the space at the side of the protrusion 134, that is, the protrusion 134 does not influence the guide block 22 to move upward and downward under the action of floating force.

In some embodiments, as shown in fig. 6, the buoyancy block 2 comprises a housing 21 and a buoyancy material (not shown in the figure), wherein the housing 21 has a sealed cavity 211 therein, and the buoyancy material is filled in the sealed cavity 211. The buoyancy material can enable the floating block 2 to still have buoyancy under the condition that the shell 21 leaks and liquid enters the sealed cavity 211, and the water level detection function of the sewage tank is not influenced.

Alternatively, the buoyant material is a non-absorbent foam, which has buoyancy that enables the buoyancy of the buoyancy block 2 by its own buoyancy in the event of a water leak in the housing 21.

In some embodiments, the waste water tank 200 further includes a residue-separating net 62, and the residue-separating net 62 is disposed in the tank body 1 below the water inlet 11 for filtering impurities in the waste water flowing out of the water inlet 11. Specifically, the sewage that flows out from water inlet 11 will flow to separating sediment net 62 downwards, and the large granule solid in the sewage is separated sediment net 62 and is filtered, and the user can take out the solid filth in separating sediment net 62 earlier when empting the sewage in sewage chamber 10, pours sewage out again, avoids solid filth to block up the sewer.

As an example, as shown in fig. 6, 7 and 9, the sewage tank 200 comprises a slag-isolating piece 6, and the slag-isolating piece 6 comprises a slag-isolating net 62 and a connecting sleeve 61. The connecting sleeve 61 is connected with the slag separation net 62, and the slag separation net 62 is of a semicircular structure and is arranged opposite to the water inlet pipeline 14 with the floating block 2. The connecting sleeve 61 is sleeved on the top of the water inlet pipeline 14 from top to bottom, and sewage flowing out of the water inlet 11 on the top of the water inlet pipeline 14 is in contact with the slag separation net 62. The user can upwards take out the sediment piece 6 from inlet channel 14 to the filth that separates on the sediment net 62 is cleared up, and the dismantlement mode is simple swift.
