Description

Technical Field

[0001] The utility model relates to the field of vacuum cleaners, in particular to a crushing vacuum cleaner. Background Art

[0002] With the increasing improvement of living quality, vacuum cleaners are widely used by people. Whether in families or general construction sites, vacuum cleaners are used for cleaning. The working principle of a vacuum cleaner is that an electric motor drives blades to rotate at high speed, generating air negative pressure in a sealed housing to suck dust debris. Vacuum cleaners can be classified into vertical, horizontal and portable types according to their structures.

[0003] Currently, Chinese Patent Publication No. CN104068789A discloses a vacuum cleaner, which includes a housing, an air inlet and an air outlet provided on the housing, and an electric motor provided in the housing. The housing includes an upper housing and a dust collection container. The upper housing is fixed to the dust collection container. The vacuum cleaner further includes a cyclone filter provided in the housing for filtering the gas entering the vacuum cleaner. The dust collection container is a telescopic dust collection container with variable volume. The dust collection container of this vacuum cleaner is designed as a telescopic dust collection container, so that when the vacuum cleaner is not working, the dust collection container can be compressed to reduce the volume of the vacuum cleaner. At the same time, the adoption of the cyclone filter can keep the air pressure in the dust collection container slightly higher than the air pressure outside the vacuum cleaner when the vacuum cleaner is working, so as to ensure that the volume of the dust collection container will not be compressed when the vacuum cleaner is working, and enable the vacuum cleaner to have a larger dust collection capacity when working.

[0004] However, when the existing vacuum cleaner is used for cleaning the hub hygiene, since lubricating oil is usually used for lubrication on the hub, it is easy to cause the suction pipe to be blocked when removing the cotton that has sucked oil and burst out in the hub, which affects the operation of the vacuum cleaner and may even cause damage to the vacuum cleaner. Summary of the Utility Model

[0005] Therefore, in view of the above problems, the utility model provides a crushing vacuum cleaner to solve the problem that the ordinary vacuum cleaner in the prior art will cause the suction pipe to be blocked when removing the cotton that has sucked oil and burst out in the hub.

[0006] To achieve the above object, the utility model adopts the following technical solutions:

[0007] A crushing vacuum cleaner includes a body and a suction pipe connected to each other; a suction motor and a dust grid bag are arranged in the body; the dust grid bag is respectively connected to the suction pipe and the output end of the suction motor in a communicating manner.

[0008] The suction pipe includes a hose and a straight steel pipe arranged at the front end of the hose; the hose is connected to the body, and a plurality of crushing components are arranged in parallel in the straight steel pipe.

[0009] The crushing assembly includes a rotating shaft arranged in the radial direction of the straight steel pipe. Both ends of the rotating shaft are rotatably connected to the inner wall of the straight steel pipe. A collar is fixedly sleeved in the middle of the rotating shaft, and several blades are circumferentially arranged on the outer wall of the collar.

[0010] A working shell is further arranged on the outer wall of the straight steel pipe. The working shell is hermetically connected to the straight steel pipe, and a placement cavity is formed between the working shell and the straight steel pipe. One end of the rotating shaft penetrates through the straight steel pipe and is fixedly connected with a first bevel gear, and the first bevel gear is located in the placement cavity. A rotating motor is arranged in the placement cavity. The output end of the rotating motor is fixedly connected with a transmission rod, and several second bevel gears matching the first bevel gear are correspondingly arranged on the transmission rod.

[0011] Further, the blades are inclined in the axial direction of the collar. The end of the blade away from the collar extends towards the inner wall of the straight steel pipe, and the width of the blade gradually decreases from the end connected to the collar towards the end away from the collar.

[0012] Further, the angle formed by the plane where the blades are located and the axial direction of the rotating collar is 20° - 70°.

[0013] Further, the blades are symmetrically distributed about the center.

[0014] Further, a cutting edge is arranged on the outer edge of the blade.

[0015] Further, several universal wheels are arranged at the bottom of the machine body.

[0016] Further, a handle is arranged at the connection between the hose and the straight steel pipe, and the handle is sleeved on the dust suction pipe.

[0018] By adopting the foregoing technical solutions, the beneficial effects of the present utility model are:

[0019] By setting up a crushing mechanism, the objects sucked into the straight steel pipe are crushed by the rotating blades, effectively avoiding the blockage of objects such as oil-absorbing cotton in the dust suction pipeline and ensuring the normal operation of the equipment; the blades are inclined in the axial direction of the collar, and the end of the blade away from the collar extends towards the inner wall of the straight steel pipe, ensuring that in the radial cross-section direction of the straight steel pipe, the rotating blades can cover a larger range, guaranteeing the crushing effect of the blades and preventing the sucked objects from getting stuck between the blades and the inner wall of the straight steel pipe; by setting up a handle, users can easily hold the dust suction pipeline, facilitating the operation and movement of the straight steel pipe for dust suction work, and at the same time, the handle also plays a role in stabilizing the connection between the straight steel pipe and the hose; by setting up a shock-absorbing mechanism inside the handle, the vibration of the straight steel pipe caused by the vibration of the rotating motor is buffered by the spring, thus ensuring the user's comfort.

[0024] The present utility model will be further described below in conjunction with the accompanying drawings and the detailed description of the preferred embodiments.

[0025] Refer to Figures 1 to 4 , this embodiment provides a crushing vacuum cleaner, which includes a body 1 and a dust suction pipeline that are connected and communicated; a dust suction motor 11 and a dust grid bag 12 are arranged inside the body 1; the dust grid bag 12 is respectively connected and communicated with the dust suction pipeline and the output end of the dust suction motor 11. The dust suction motor 11 is used to form a negative pressure inside the body 1 to generate suction, so that sundries enter the body 1 through the dust suction pipeline; the dust grid bag 12 is used to collect the absorbed dust, sundries, etc.

[0026] The dust suction pipeline includes a hose 2 and a straight steel pipe 3 arranged at the front end of the hose 2; the hose 2 is connected to the body 1, and a plurality of crushing components are arranged in parallel inside the straight steel pipe 3. The hose 2 is convenient for adjusting the direction of the straight steel pipe 3 and facilitating the movement of the straight steel pipe 3, and can accurately target the area to be cleaned for operation, improving the cleaning efficiency and effect. Preferably, the number of the crushing components is 2 - 5.

A shock absorption mechanism is arranged inside the grip 5, and the shock absorption mechanism includes a plurality of springs 51 evenly arranged inside the grip 5. Two ends of each spring 51 are fixedly connected to the dust suction pipe and the grip 5 respectively. By providing the grip 5, a user can easily hold the dust suction pipe, facilitating the operation and movement of the straight steel pipe 3 for dust suction work. Meanwhile, the grip 5 also plays a role in stabilizing the connection between the straight steel pipe 3 and the flexible hose 2. By arranging the shock absorption mechanism inside the grip 5, the vibration of the straight steel pipe 3 caused by the vibration of the rotary motor 45 is buffered by the springs 51, thus ensuring the comfort of the user during use.
