Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, 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, generating negative air pressure in a sealed housing, and then sucking dust through an external suction pipe.

[0003] Vacuum cleaners can be divided into upright, horizontal and portable types according to their structure. 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 mounted to the floor brush holder around a first direction, a receiving space is defined inside the motor cover, the motor cover has an opening, and the connecting pipe is configured to be rotatably connected to the opening around a second axis different from the first direction; and 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, the 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, which makes the control simple and convenient. For example, Chinese patent CN112190174A discloses a handheld vacuum cleaner comprising a housing, a dust cup connected to the housing and internally performing cyclonic dust removal, a motor disposed within the housing and downstream of the dust cup, and a battery disposed in parallel with the motor. The dust cup includes a cyclonic chamber and a dust collection chamber connected to the cyclonic chamber via an ash ejection port. The central axis of the motor passes through the cyclonic chamber, while the central axis of the battery passes through the dust collection chamber. This device has the advantages of increasing dust storage capacity, improving filtration performance, conforming to ergonomics, and being user-friendly.

[0004] Due to the limited size of handheld vacuum cleaners, their structure is relatively simple, primarily separating dust through a filter. Consequently, over extended periods of use, dust easily adheres to the filter, reducing its air permeability and, in turn, reducing suction power and even causing the machine to clog. Utility Model Content

[0005] The purpose of the utility model is to provide a high-efficiency cyclone separation structure for a vacuum cleaner, so as to solve the problem of reduced suction force and clogging caused by decreased air permeability of the filter when the vacuum cleaner is in use.

[0006] In order to achieve the above-mentioned purpose, 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 inside;

[0008] The dust cup is detachably mounted on the main unit of the vacuum cleaner, 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 circumferentially along the rotating shaft;

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

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

[0012] The vacuum cleaner main body 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 parallel convex ribs.

[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 handle surface is provided with an anti-slip decorative piece, which is detachably mounted 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 provided at the end of the anti-slip decorative piece, and a socket corresponding to the connector is provided 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 provided on the inner wall of the dust cup. An end face with an arc-shaped cross section is provided 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 this utility model, when using the vacuum cleaner, hold the handle of the vacuum cleaner main unit and press the on / off button to start the motor. The motor generates suction and drives the separation cone to rotate at high speed, generating centrifugal force. When dust is sucked into the dust cup through the air inlet pipe, it rotates against the dust cup cavity under the centrifugal force of the separation cone, thus preventing the air permeability of the filter from decreasing, preventing the machine from being blocked or stalled.

[0031] 2. In this utility model, the battery compartment cover is fixedly mounted on the anti-slip decorative sheet, improving the connection reliability between the anti-slip decorative sheet and the battery compartment cover, and preventing the battery compartment cover from falling off. The battery compartment cover and the anti-slip decorative sheet utilize their connection to achieve self-locking, and also effectively simplifies the connection structure of the battery compartment cover and the anti-slip decorative sheet.
