As a preference, the air outlet of the suction motor is connected to the inlet of the blowing pipe through the motor air outlet, the motor air outlet is inside the upper cover, and the air outlet direction of the air suction motor is horizontal , the air intake direction of the suction motor is vertical.

Preferably, the bottom of the vertical valve pipe is provided with several bottom through holes, and the bottom through holes communicate with the dust collection part, and the filter screen cylinder is provided with a filter cover.

The beneficial effects of the utility model are: it can efficiently absorb dust and water, and has a blowing function, which has a strong cleaning ability; it has a suction limiting function, and when the water volume reaches a limited height, the floating valve core will completely move up to block the air inlet interface At this time, it is impossible to continue vacuuming, which can avoid continuous inhalation of garbage and dust when there is too much garbage in the dust collection bucket; from air intake to exhaust, follow a fixed and well-structured channel, without redundant detours, and the connection between pipelines is stable. The air suction capacity of the suction motor can be fully exerted, the relative energy consumption can be reduced, and it is environmentally friendly.

detailed description

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.

In the embodiment shown in Figures 1 and 2, a self-blocking vacuum cleaner structure includes a dust collection bucket 1 and an upper cover 2, and the dust collection bucket is provided with a connecting seat 3 for connecting a dust suction pipe, Described upper cover is provided with exhaust outlet, air blowing pipe 4, is provided with the suction motor 5 of band guide vane in described upper cover, the air outlet of suction motor and the inlet of blowing pipe and the air outlet are both connected, the outlet of the blowing pipe is the blowing outlet, the upper cover is provided with an exhaust cover, the exhaust cover is hinged or clipped to the upper cover, and the exhaust cover is The cover seals the blowing and exhaust port, and the filter cylinder 6 is arranged in the dust collection bucket, the axis of the filter screen cylinder is parallel to the axis of the dust collection bucket, and the distance between the filter screen cylinder and the inner wall of the dust collection bucket is The space between them is the dust collection part 7, and the vertical valve pipe 8 is provided in the filter cylinder, and several communication ports are provided on the vertical valve pipe, and the floating valve pipe that can slide up and down in the vertical valve pipe is provided The valve core 9 is provided with an air inlet port 10 on the upper cover, the upper end of the air inlet port communicates with the air inlet of the suction motor, and the top end of the vertical valve pipe is connected with the lower end of the air inlet port. Required impellers, blades, etc. can be set on the suction motor to improve the suction effect, and the suction motor is the power source for internal air circulation. When the suction motor is working, the air enters the dust bucket from the suction pipe through the connecting seat, then passes through the filter cylinder and enters the air inlet interface, and then is discharged through the suction motor and the air outlet. During this process, dust, garbage, and water are sucked into the dust collection bucket together, but only the air is discharged, while the dust, garbage, water, etc. are left in the dust collection bucket. When the water volume reaches a certain level, the buoyancy will cause the floating valve core to move up. When the water volume reaches a limited height, the floating valve core will completely block the air inlet interface. At this time, the vacuuming cannot continue, and the dust collection bucket needs to be cleaned. , to avoid continuous inhalation of garbage and dust when there is too much garbage in the dust collection bucket, resulting in blockage or damage to the dust collection bucket. In addition, the air blowing pipe can be used not only as an auxiliary air outlet channel, but also as an air blowing channel. The air blowing pipe can be connected to the air pipe to clean the corners and other places.

The air outlet of the suction motor is connected with the inlet of the air blowing pipe through the motor air outlet 12, the air outlet of the motor is in the upper cover, and the air outlet direction of the suction motor is horizontal, so The air intake direction of the described suction motor is vertical.

The bottom of the vertical valve pipe is provided with several bottom through holes, and the bottom through holes communicate with the dust collecting part, and the filter screen cylinder is provided with a filter cover. The through hole is connected with the dust collection part, so when the water in the dust collection part accumulates to a certain height, it will directly affect and enter the vertical valve pipe, driving the floating valve core to move up, and the floating valve core responds faster and more sensitively.
