[0027] Example: Figure 1-7 As shown, this utility model discloses an embodiment of a vacuum cleaner with a cyclone separation device, which includes: a body, a cyclone separation device 300 connected to the body, a vacuum motor 400 disposed in the body and located downstream of the cyclone separation device 300, and a battery pack 500 connected to the body and supplying power to the vacuum motor 400.

[0028] The main body is a one-piece injection molded part, including a handle body 100 and a motor body 200 connected to the handle body 100, located above the cyclone separator 300, and housing the vacuum motor 400. The handle body 100 includes a connecting body 120 located at the top and adjacent to the motor body 200, and a battery body 140 located at the bottom and adjacent to the cyclone separator 300, fixing the battery pack 500. The connecting body 120 and the battery body 140 are connected by a handle, which is convenient for the user to hold. The motor body 200 includes a motor body cavity 204 located therein, an air inlet 220 located at the front end of the motor body cavity 204 and guiding the dirty airflow into it, and a motor rear exhaust filter 240 detachably located at the top of the motor body cavity 204 and downstream of the vacuum motor 400.

[0029] The upper end of the cyclone separator 300 extends at least partially into the motor housing cavity 204. It includes a cyclone chamber 304, a mesh cover 320 located within the cyclone chamber 304, a secondary cyclone component 330 located within and downstream of the mesh cover 320, a dust cup cover 340 that covers the bottom of the cyclone chamber 304, a bottom-opening cover 350 located at the bottom of the cyclone chamber 304 and above the dust cup cover 340, and a locking button 308 that engages with one end of the bottom-opening cover 350. The cyclone chamber 304 has a roughly circular cross-section, and the mesh cover 320 is roughly annular with several mesh holes on its outer surface. The secondary cyclone component 330 includes multiple cyclones 332 located at the upper end and a dust collection chamber 336 located at the lower end for collecting dust generated by the cyclones. The dust cup cover 340 includes a cover body 342, a protrusion 344 located within the cyclone chamber 304 and protruding from the surface of the cover body 342 to prevent dust from being stirred up, a positioning hole 345 at one end of the cover body 342, an unlocking end 346 at the other end of the cover body 342, and a pair of rotating shaft arms 348 adjacent to the unlocking end 346 and having a rotating shaft hole. The protrusion 344 is located outside the secondary cyclone component 330 and inside the cyclone separator 300. The protrusion 344 is located between the positioning hole 345 and the unlocking end 346. The projection surface of the mesh cover 320 along the central direction at least partially coincides with the projection surface of the protrusion 344. The protrusion 344 has an inclined surface, which gradually decreases relative to the bottom plane of the dust cup cover 340 in the direction facing the cyclone airflow. The bottom opening cover 350 includes an opening 354, a latching end 356 located at one end of the opening 354, a pivot end 358 located at the other end of the opening 354, and a receiving portion 357 located between the opening 354 and the pivot end 358 and internally capable of at least partially accommodating the unlocking end 346, wherein the cup cover body 342 of the dust cup cover 340 covers the opening 354.

[0030] In this embodiment, a sealing member is further included between the dust cup cover 340 and the bottom opening cover 350, and a magnetic suction member is also included between the dust cup cover 340 and the bottom opening cover 350. A portion of the sealing member can be inserted into the positioning hole 345 for positioning, and the magnetic suction member is used for magnetic locking between the dust cup cover 340 and the bottom opening cover 350.

[0031] In this embodiment, a torsion spring assembly 359 is further included, which is coaxially arranged with the pivot arm 348 and housed in the receiving part 357. The torsion spring assembly 359 includes a shaft inserted into the pivot hole and a torsion spring sleeved on the shaft. The torsion spring assembly 359 provides a torsion spring force to the unlocking end 346, and through the magnetic attraction of the magnetic member, it keeps the dust cup cover 340 reliably covering the opening 354, preventing dust in the cyclone chamber 304 and the dust collection chamber 336 from falling out of the opening 354.

[0032] The vacuum motor 400 is preferably a DC motor, and its center direction coincides with the center direction of the cyclone separator 300. The vacuum motor 400 is located above the cyclone separator 300.

[0033] The battery pack 500 is preferably a lithium battery, but can also be other rechargeable batteries such as nickel-metal hydride batteries.

[0034] During operation, the dirty airflow enters from one end of the air inlet 220 and then tangentially enters the cyclone chamber 304 from the other end of the air inlet 220 to generate a primary cyclone. Due to the height difference between the air inlet 220 and the dust cup cover 340, large dust particles fall onto the cup cover 342 under the action of centrifugal force and gravity of the cyclone. Since the large dust particles will collide with the upstream end of the protrusion 344, which is perpendicular to the cup cover 342, they are easily prevented from rising. Moreover, the dust particles are also easy to walk down the slope to prevent them from rising again, avoid multiple cyclones, and reduce the probability of the mesh cover being blocked. The airflow containing fine dust passes through the mesh of the mesh cover 320 and enters the secondary cyclone component 330. It undergoes secondary cyclone filtration through the cyclone separator 332. The dust after the secondary cyclone falls into the dust collection chamber 336. The dust cup cover 340 also covers the bottom of the dust collection chamber 336, so opening the dust cup cover 340 can simultaneously empty the dust in the cyclone chamber 304 and the dust collection chamber 336.

[0035] The advantages of this invention are: preventing dust, reducing the probability of the mesh cover being blocked, improving cyclone separation performance, and increasing dust removal efficiency.

[0036] The above are merely preferred embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and improvements made by those skilled in the art without departing from the inventive concept of the present utility model should be covered within the protection scope of the present utility model.
