Background

A vacuum cleaner is a cleaning tool with wide application. The working principle of the dust collector is that a motor is used for driving blades to rotate at a high speed, air negative pressure is generated in a sealed shell, and dust is sucked. Common vacuum cleaners are horizontal type, vertical type, handheld type and the like. The handheld dust collector is widely applied due to small size and convenient carrying and use.

The handheld vacuum cleaner is limited in size and has the disadvantages of low power and insufficient suction strength compared with other types of vacuum cleaners. To improve the cleaning ability of the hand-held cleaner, it is generally provided with a cyclonic separating structure. The cyclone separation structure can separate dust and debris by utilizing the principle of centrifugal force, thereby improving the cleaning capability of the dust collector. However, the air inlet mechanism of the existing cyclone separation structure is too complex, the power of a motor of the dust collector cannot be effectively utilized, and the volume of the whole cyclone separation structure is too large, so that the cleaning capability of the dust collector is influenced.

Therefore, the utility model provides a whirlwind formula air inlet structure of dust catcher, including the dirt cup, the dirt cup includes dirt cup and dirt cup, dirt cup detachable installs on the dirt cup, be provided with filtering mechanism in the dirt cup, filtering mechanism includes the air inlet subassembly, filtering component and filter screen, the air inlet subassembly joint is in the dirt cup, the air inlet subassembly includes intake stack and air-out pipeline, the structure of air-out pipeline is the arc, arrange along the circumference of intake stack, the air current that has debris gets into the intake stack from the intake stack of dirt cup, flow from the air-out pipeline, the filtering component cover is established on the intake stack, filtering component's tip supports on the dirt cup, filtering component includes annular filter screen mounting bracket, the filter screen cover is established on the filter screen mounting bracket.

Further, the air inlet pipeline and the air inlet channel are eccentrically arranged.

Further, a second-stage filter frame is arranged in the filter screen mounting frame.

Furthermore, a sealing ring is sleeved on the end part of the filtering component.

Further, the structure of the sealing ring is trumpet-shaped.

Further, the filter screen is a steel mesh.

The utility model provides a pair of whirlwind formula air inlet structure of dust catcher, the air current that has debris gets into the air inlet pipe of air inlet subassembly by the intake duct of dirt cup lid in, then realizes the rotary motion of air current through the air-out pipeline of air inlet subassembly, and the whirlwind formula air inlet simple structure of dust catcher is direct, effectively improves the utilization efficiency of dust catcher motor power. The rotation of air current makes during bigger debris fall into the dirt cup under the effect of inertial centrifugal force, and when the air current got into the filter assembly on the intake stack, the air current was filtered once more to the filter screen of steel mesh material. The airflow filtered by the filter screen is further filtered by a secondary filter rack in the filter assembly, and the cleaning capability of the dust collector is greatly improved by multi-stage filtration.

The utility model provides a pair of whirlwind formula air inlet structure of dust catcher, the air current that has debris directly gets into the intake stack of air inlet subassembly from the dirt cup to accomplish the rotation of air current through the air-out pipeline of air inlet subassembly, the high-efficient power that utilizes the dust catcher motor.

Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

The first embodiment is as follows:

referring to fig. 1 to 3, which illustrate a cyclone air intake structure of a vacuum cleaner provided by an embodiment of the present invention, the cyclone air intake structure comprises a dust cup, the dust cup comprises a dust cup body 1 and a dust cup cover 2, the dust cup cover 2 is detachably mounted on the dust cup body 1, a filtering mechanism is arranged in the dust cup body 1, the filtering mechanism comprises an air intake component 3, a filtering component 4 and a filter screen 5, the air intake component 3 is clamped in the dust cup body 1, the air intake component 3 comprises an air intake duct 31 and an air outlet duct 32, the air outlet duct 32 is arc-shaped, the air inlet duct 31 is circumferentially arranged, air flow with impurities enters the air inlet duct 31 from the air inlet duct 21 of the dust cup cover 2 and flows out from the air outlet duct 32, the filter assembly 4 is sleeved on the air inlet duct 31, the end part 41 of the filter assembly 4 abuts against the dust cup cover 2, the filter assembly 4 comprises an annular filter screen mounting frame 42, and the filter screen 5 is sleeved on the filter screen mounting frame 42.
