Description

Technical Field

[0001] The invention relates to the technical field of vacuum cleaners, and in particular to a high-efficiency cyclone separation structure of a vacuum cleaner. Background Art

[0002] A vacuum cleaner is a widely used cleaning device. The working principle of a vacuum cleaner is to use an electric motor to drive the blades to rotate at high speed, generate negative air pressure in a sealed shell, and then suck up dust through an external suction pipe.

[0003] Vacuum cleaners can be divided into vertical, horizontal and portable types according to their structures. For example, Chinese patent CN105361799A discloses a vacuum cleaner and an upright vacuum cleaner, which include: a body with a connecting pipe; a floor brush holder, in which a roller brush is installed; a motor cover, which is rotatably installed on the floor brush holder around a first direction, a receiving space is defined inside the motor cover, and an opening is provided on the motor cover, and the connecting pipe is configured to be rotatably connected to the opening around a second axis different from the first direction; a motor, which is arranged in the receiving space and is used to drive the roller brush to rotate relative to the floor brush holder around a third axis parallel to the first axis. In this solution, dust collection and roller brush movement can be controlled simultaneously by one motor, which reduces the difficulty of control, is simple to manufacture, has low cost, and is easy to use. In addition, the body of the vacuum cleaner can have two degrees of freedom in two directions, so that the running direction of the floor brush holder can be controlled by driving the body, such as a handle, in two directions, and the control is simple and convenient. For another example, Chinese patent CN112190174A discloses a handheld vacuum cleaner, which includes a body, a dust cup connected to the body and having cyclone dust removal inside, a motor arranged in the body and located downstream of the dust cup, and a battery arranged in parallel with the motor, wherein the dust cup includes a cyclone chamber and a dust collecting chamber connected to the cyclone chamber via an ash throwing port, and the central axis of the motor passes through the cyclone chamber, while the central axis of the battery passes through the dust collecting chamber. Its advantages are that it can increase the ash storage capacity, improve the filtering performance, conform to ergonomics, and is convenient for users to use.

[0004] When using a handheld vacuum cleaner, due to the size limitation of the vacuum cleaner, the structure of the vacuum cleaner is relatively simple, and dust is mainly separated by filtering through the filter. Therefore, when the handheld vacuum cleaner is used for a long time, dust is easy to adhere to the filter of the vacuum cleaner, resulting in a decrease in the air permeability of the filter, which in turn reduces the suction power of the machine and even causes blockage. Summary of the invention

[0005] The object of the present invention is to provide a high-efficiency cyclone separation structure for a vacuum cleaner to solve the problem of reduced suction and blockage caused by reduced air permeability of a filter when the vacuum cleaner is in use.

[0006] In order to achieve the above object, the present invention adopts the following technical solution: a high-efficiency cyclone separation structure of a vacuum cleaner, comprising:

[0007] A vacuum cleaner host, which has a motor disposed therein;

[0008] A dust cup is detachably mounted on the vacuum cleaner main unit, and an eccentrically arranged air inlet pipe is provided at the end of the dust cup;

[0009] A separation cone is rotatably mounted in the dust cup, and is provided with blades arranged along the circumference of the rotating shaft;

[0010] The filter screen is arranged in the dust cup.

[0011] As a further description of the above technical solution:

[0012] The vacuum cleaner host is provided with a handle, and the handle is provided with a switch button.

[0013] As a further description of the above technical solution:

[0014] The surface of the switch button is provided with a plurality of convex ribs arranged in parallel.

[0015] As a further description of the above technical solution:

[0016] A detachable battery compartment cover is provided at the bottom of the handle.

[0017] As a further description of the above technical solution:

[0018] The surface of the handle is provided with an anti-skid decorative sheet, and the anti-skid decorative sheet is detachably installed on the handle.

[0019] As a further description of the above technical solution:

[0020] The surface of the anti-slip decorative sheet is provided with convex bumps arranged in an array.

[0021] As a further description of the above technical solution:

[0022] The convex hull is hemispherical.

[0023] As a further description of the above technical solution:

[0024] A connector is arranged at the end of the anti-slip decorative sheet, and a socket corresponding to the connector is arranged on the handle.

[0025] As a further description of the above technical solution:

[0026] The battery compartment cover is fixedly mounted on the anti-slip decorative sheet.

[0027] As a further description of the above technical solution:

[0028] A support ring is arranged on the inner wall of the dust cup, and an end face with an arc-shaped cross section is arranged on the support ring, and the end face contacts the separation cone.

[0029] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0030] 1. In the present invention, when the vacuum cleaner is used, the handle of the vacuum cleaner main unit is held and the switch button is pressed, the motor starts to work, the machine generates suction under the rotation of the motor and drives the separation cone to rotate at high speed to generate centrifugal force. When dust is sucked up and enters the dust cup through the air inlet pipe, it will rotate along the dust cup cavity under the action of the centrifugal force of the separation cone, thereby avoiding the phenomenon of too low suction or blocking of the machine due to the decrease in the air permeability of the filter.

[0031] 2. In the present invention, the battery compartment cover is fixedly mounted on the anti-slip decorative sheet, which improves the connection reliability of the anti-slip decorative sheet and the battery compartment cover and prevents the battery compartment cover from falling off. The battery compartment cover and the anti-slip decorative sheet utilize each other's connection to achieve self-locking, and also effectively simplifies the connection structure of the battery compartment cover and the anti-slip decorative sheet.
