[0023] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0024] Example: Figure 1-4 As shown, the utility model discloses an embodiment of a portable wet vacuum cleaner for preventing liquid backflow, which includes: a body 100 having an air inlet pipe 120, a nozzle 130, and a handle 160, a dust cup 200 connected to the air inlet pipe 120 and located on one side of the handle 160 and detachable, a vacuum generating unit 300 arranged at one end of the handle 160 and connected to the dust cup 200 by air flow, a separator 500 arranged in the dust cup 200 and having a separation chamber 510, a cleaning box 400 arranged at the other end of the handle 160 and connected to the nozzle 130, and a water vapor separation component 600 arranged in the separation chamber 510, a dust cup cover 700 snap-fittedly connected to the upper end of the dust cup 200 and shielding the water vapor separation component 600, a pump 800 arranged in the body 100 and located between the air inlet pipe 120 and the cleaning box 400 and connected to the cleaning box 400, and a power plug 900 electrically connected to the vacuum generating unit 300.

[0025] The body 100 is made of injection molding material and is integrally formed, wherein the air inlet pipe 120 and the nozzle 130 are detachably connected to the body 100, the air inlet pipe 120 is generally in the shape of a figure 7, and when the portable wet vacuum cleaner is placed horizontally, the air inlet direction of the air inlet pipe 120 is horizontal. The body 100 includes a motor part 160 that accommodates the vacuum generating unit 300, and a connecting part 190 that is connected to the motor part 180 at the bottom and is located on one side of the handle 160 and close to the dust cup 200. The body 100 also includes an air outlet pipe 140 that connects the air outlet end of the dust cup 200 to the vacuum generating unit 300, wherein the air outlet pipe 140 is covered by the connecting part 190. The nozzle 130 is located downstream of the pump 800 and adjacent to the air inlet pipe 120.

[0026] The dust cup 200 includes a dust cup handle 220 disposed at the front end of the dust cup 200, which is disposed away from the vacuum generating unit 300. The dust cup 200 is an injection molded part with an upper end opening and a lower end closed and having a dust cup inner cavity. The dust cup cover 700 is used to close the upper end opening of the dust cup 200 and is provided with a filter 720 at the air outlet end, and a connecting pipe 740 connected to the air inlet pipe 120 is provided at the air inlet end. The connecting pipe 740 extends in at least two directions, namely, extending along the inner side wall and extending away from the inner side wall.

[0027] The central axis direction of the vacuum generating unit 300 is parallel to the horizontal direction or intersects with the horizontal direction at a non-right angle. At this time, the portable wet vacuum cleaner in this embodiment is placed horizontally.

[0028] The cleaning box 400 is used to store cleaning liquid and is located at the upper end of the handle 160 .

[0029] The separator 500 is a plastic part with an open upper end and a substantially closed lower end. The separation of water, solids and gas is achieved through the separation chamber 510. The separator 500 also includes a plurality of through holes 520 arranged at the bottom of the separation chamber 510, so that the two ends of the through holes 520 form a dry garbage collection space and a liquid collection space. The separation chamber 510 contains a dry garbage collection space or a fixed garbage collection space, while the outside of the separation chamber 510 of the separator 500 is a liquid collection space. When the portable wet vacuum cleaner is placed horizontally, the dry garbage collection space is located above the liquid collection space.

[0030] The water-gas separation assembly 600 includes a water outlet pipe 640 connected to the connecting pipe 740, a water level detector 620 disposed in the water outlet pipe 640 and extending protruding into the separation chamber 510, an arc-shaped air inlet 660 disposed away from the water outlet pipe 640, and an air outlet pipe 680 having one end connected to the downstream of the arc-shaped air inlet 660 and the other end connected to the filter element 720. The water level detector 620 is close to the center of the dust cup 200, so that there is a gap between the water level detector 620 and at least two side walls of the dust cup 200. When the portable wet vacuum cleaner is placed horizontally, the bottom side wall of the dust cup 200 is roughly flat and placed on a horizontal plane, and there is a gap between the water level detector 620 and the bottom side wall, the front side wall, the rear side wall, and the dust cup cover of the dust cup 200, wherein the distance between the water level detector 620 and the bottom side wall is greater than the distance between the water level detector 620 and the front side wall. The distance between the water level detector 620 and the front side wall is smaller than the distance between the water level detector 620 and the rear side wall. The dust cup handle 220 is located on the front side wall of the dust cup 200. The arc-shaped air inlet 660 is arranged between the air outlet pipe 680 and the rear side wall and guides the air flow to enter. The air inlet end of the arc-shaped air inlet 660 and the water outlet end of the water outlet pipe 640 are in a diagonal position relative to the air outlet pipe 680, thereby ensuring that whether the portable wet vacuum cleaner is placed horizontally or vertically, the air inlet end of the arc-shaped air inlet 660 is higher than the water outlet end of the water outlet pipe 640, preventing liquid from entering the vacuum generating unit 300 to ensure reliable operation. The air outlet pipe 680 is arranged adjacent to the air outlet pipe 680.

[0031] The separator 500 and the water-gas separation assembly 600 are locked by rotating the buckle to form a detachable assembly, which is convenient for removal from the dust cup 200 and more convenient for separate dumping of dry garbage. The remaining sewage is retained at the bottom of the dust cup 200.

[0032] The utility model has the advantages of small size, easy operation, and portability, and is suitable for cleaning in narrow areas.

[0033] The above are only preferred implementations of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technician familiar with the technical field can make several modifications and improvements without departing from the creative concept of the present utility model, which should be included in the protection scope of the present utility model.
