The present disclosure provides a surface cleaning apparatus for sucking dirt on a surface of an object by suction, and then separating the dirt to remain in the apparatus, and discharging separated clean air, thereby achieving the purpose of cleaning the surface of the object.

The surface cleaning apparatus of the present disclosure comprises a machine body 100 and a dust cup filter device 300, wherein the machine body 100 is provided with a motor assembly 200 and a clean air outlet 104, the clean air outlet 104 being located at the air outlet side of the motor assembly 200, the dust cup filter device 300 being attached to the machine body 100 and being located at the air inlet side of the motor assembly 200. The dust cup filter 300 comprises a first dust cup 301, a second dust cup 302, a cyclone assembly 340 and an air inlet channel 303; the first dust cup 301 is internally provided with a cyclone chamber 304, and the air inlet channel 303 is communicated with the top of the cyclone chamber 304 and is used for allowing external air to enter the cyclone chamber 304; the cyclone assembly 340 is disposed in the cyclone chamber 304, and is configured to generate a cyclone by driving the motor assembly 200 so as to separate dust from air entering the cyclone chamber 304; the second dust cup 302 has a dust collecting chamber 305 therein, and a dust guiding structure 320 for allowing the cyclone dust particles to enter the dust collecting chamber 305 is disposed between the second dust cup 302 and the first dust cup 301. The present disclosure adopts a dual-dust-cup design, so that dust particles in an air flow enter a dust collecting chamber 305 of a second dust cup 302 through a dust guiding structure 320 in a cyclone separation process of the cyclone chamber 304, more cyclone separation spaces are reserved for a first dust cup 301, resistance of the dust particles in the cyclone separation spaces to the air flow is reduced, cyclone separation effect is improved, dust particles entering a filtering component downstream of the air flow are reduced, and suction loss is reduced. In addition, the air inlet channel 303 is communicated with the top of the cyclone chamber 304, and the motor assembly 200 is close to the top of the cyclone chamber 304, so that the airflow path is positioned at the upper part of the first dust cup 301 and close to the motor, the airflow path is shortened, and the suction loss is further reduced.

In the present disclosure, a first airflow inlet 306 communicating with a cyclone chamber 304 is provided on a first dust cup 301, an air inlet channel 303 is at least partially located above a second dust cup 302, and a dust-laden airflow entering the air inlet channel 303 enters the cyclone chamber 304 through the first airflow inlet 306 in a tangential direction for dust-gas separation.

Wherein the air inlet channel 303 is at least partially located above the second dust cup 302, optionally, the air inlet channel 303 bypasses the second dust cup 302 and is connected with the first air flow inlet 306; alternatively, the air inlet passage 303 passes through an upper portion of the dust collection chamber 305 to be connected to the first air flow inlet 306. Further alternatively, the air inlet channel 303 bypasses partly the second dirt cup 302 and partly passes through the upper part of the dirt collection chamber 305 to be connected to the first air flow inlet 306.

Wherein the tangential entry of the airflow into the cyclone chamber 304 means that the airflow enters the cyclone chamber 304 in a direction tangential to the inner wall of the first dirt cup 301. In particular, the air inlet channel 303 has an extension in the tangential direction of the inner wall of the first dirt cup 301 at the first air flow inlet 306, the extension being located on the side of the air inlet channel 303 adjacent to the cyclone chamber 304. Further, the extension section occupies more than one third of the length of the air inlet channel 303, or the air inlet channel 303 may extend along the tangential direction of the inner wall of the first dust cup 301 at the first airflow inlet 306 along the whole length. In this structure, the airflow enters tangentially and is guided to the space between the cyclone assembly 340 and the inner wall of the first dirt cup, the airflow is not blocked by the cyclone assembly 340 at the beginning of entering the cyclone chamber, which is conducive to the formation of cyclone airflow, and the hair and dust in the airflow are not attached to the cyclone assembly 340, which ensures the smoothness of the airflow at the inlet. In addition, the air inlet channel 303 is at least partially arranged above the second dust cup 302, so that space occupation is reduced.

The conducting opening 324 of the dust guiding structure 320 and the first airflow inlet 306 are arranged close to each other, and the conducting opening 324 and the first airflow inlet 306 are located on the same side of the first dust cup 301 in the axial direction. Preferably, the through opening 324 and the first airflow inlet 306 are both located axially above the first dirt cup 301. There is at least a portion of the airflow along the airflow path, and the actual distance of movement from the first airflow inlet 306 to the through opening 324 is less than or equal to the full circumferential distance of the at least a portion of the airflow along the airflow path. Wherein the through opening 324 is located at a position where the airflow from the first airflow inlet 306 is less than one revolution in the cyclone chamber 304. The airflow flows in the space between the inner wall of the first dust cup 301 and the cyclone assembly 340, one cyclone circle refers to that the airflow winds around the inner wall of the first dust cup or the cyclone assembly, and the cyclone is not enough that the first airflow inlet 306 and the conducting port 324 are arranged on the same circle of the cyclone path, and the airflow flows out from the conducting port 324 after entering the cyclone chamber 304 from the first airflow inlet 306 and winding around the inner wall of the first dust cup 301 or the cyclone assembly 340 for less than one circle. The conducting port 324 can be arranged at 1/4 or 1/2 or 3/4 of the circle of the cyclone by taking the first air flow inlet 306 as a starting point, and can also be arranged at any position with less than the circle of the cyclone. Unlike prior art schemes in which the cyclone separation effect is improved by increasing the spatial distance between the inlet and outlet of the dust cup, the present disclosure provides the first airflow inlet 306 and the conduit 324 in close proximity, which enables hair to enter the dust chamber 305 without multiple cyclone filtration in the cyclone chamber, preventing the hair from being entangled on the cyclone assembly 340 due to multiple cyclone filtration, and in addition, dust falling in the cyclone chamber 304 due to insufficient cyclone separation is lifted up and re-enters the dust chamber 305 with the continued cyclone. Compared with the scheme of increasing the space distance between the dust cup inlet and the dust cup outlet in the prior art, the cyclone assembly 340 can reduce and avoid the winding of hair, reduce the blocking risk of the filtering piece and can obtain better dust-gas separation effect.

The cyclone assembly 340 comprises a third dust cup 341, a cyclone screen 342, a cyclone cone 343, an adjusting ring 344 and a cyclone upper cover 345, wherein the third dust cup 341 is vertically arranged in the cyclone chamber 304, the cyclone upper cover 345 covers the top opening of the third dust cup 341, the cyclone screen 342 surrounds the outer wall of the third dust cup 341, the upper end of the cyclone screen 342 is connected with the cyclone upper cover 345, the lower end of the cyclone screen 342 is connected with the third dust cup 341, the cyclone cone 343 is arranged at the top opening of the third dust cup 341, the adjusting ring 344 penetrates through the cyclone cone 343 to enter the third dust cup 341, and the adjusting ring 344 is communicated with an upper cover air outlet 346 of the cyclone upper cover 345.

Specifically, a second airflow inlet 347 is disposed between the cyclone screen 342 and the cyclone cone 343, and the second airflow inlet 347 allows air separated from the air in the cyclone chamber 304 to enter the third dust cup 341. The middle part of the cyclone cone 343 is provided with a through hole, the upper cover air outlet 346 is connected with the upper end opening 351 of the adjusting ring 344 at the through hole, and a third air flow inlet 348 is arranged on one side of the adjusting ring 344 away from the cyclone cone 343. As shown in fig. 3, the third air inlet 348 is a plurality of holes formed in the sidewall of the adjusting collar 344. The third dust cup 341 has a separation space 349 and a dust collecting space 350 inside, the separation space 349 is close to the cyclone upper cover 345, the dust collecting space 350 is close to the bottom of the first dust cup 301, and the cyclone screen 342 surrounds the separation space 349. Wherein the separation space 349 and the dust collecting space 350 are substantially cylindrical, the diameter of the dust collecting space 350 is smaller than that of the separation space 349, and a transition portion of the separation space 349 and the dust collecting space 350 is an arc surface so as to guide dust particles to fall into the dust collecting space 350 from the separation space 349 while preventing cyclone generated in the upper separation space 349 from agitating dust particles collected in the lower dust collecting space 350.

The motor assembly 200 operates to cause the separation space 349 of the third dust cup 341 and the cyclone chamber 304 of the first dust cup 301 to generate cyclone force, the air inlet channel 303 generates suction force, external air flows from the air inlet channel 303 into the first dust cup 301, primary dust-air separation is performed in the cyclone chamber 304, dust particles after the primary dust-air separation enter the dust collection chamber of the second dust cup 302 through the dust guide structure 320, air after the primary dust-air separation enters the third dust cup 341 through the cyclone screen 342, the second air flow inlet 347 and the cyclone cone 343, secondary cyclone separation is performed in the separation space 349, the dust particles after the secondary cyclone separation fall into the dust collection space 350 at the bottom of the third dust cup 341, and the air after the secondary cyclone separation enters the upper cover air outlet 346 through the third air flow inlet 348 and the upper end opening 351 on the adjusting ring 344, and then enters the motor assembly 200. As shown in fig. 4, the solid arrows in the figure indicate the flow direction of the air flow, and the broken arrows indicate the flow direction of the dust particles.

The first dust cup 301 is arranged adjacent to the second dust cup 302, the first dust cup 301 is provided with a first dust guiding opening, the second dust cup 302 is provided with a second dust guiding opening, and the dust guiding structure 320 is communicated with the first dust guiding opening and the second dust guiding opening. In one possible implementation manner, a common side wall 310 is disposed between the first dust cup 301 and the second dust cup 302, the first dust guiding opening and the second dust guiding opening are both disposed on the common side wall 310, and the first dust guiding opening and the second dust guiding opening are mutually overlapped to form a common dust guiding opening 307, and the common dust guiding opening 307 is located in the middle of the common side wall 310. The first dust cup 301 and the second dust cup 302 may be integrally formed or separately formed and then integrally connected. When the first dust cup 301 and the second dust cup 302 are integrally formed, the common side wall 310 and the common dust guide opening 307 are formed, so that the design simplifies the manufacturing process and has high production efficiency.

In one possible implementation, the common sidewall 310 may also be mounted between the first dirt cup 301 and the second dirt cup 302 after being formed, at least in part, as a separate component. As shown in fig. 10, a through hole 313 is provided at the connection between the first dust cup 301 and the second dust cup 302, the through hole 313 penetrates at least through the middle regions of the first dust cup and the second dust cup in the vertical direction, the common side wall 310 can be assembled at the through hole 313 to form a wall shared by the first dust cup and the second dust cup, the common side wall 310 is provided with a common dust guiding opening 307, and the common dust guiding opening 307 is located at the middle region of the first dust cup 301 and the second dust cup 302 in the vertical direction.

The air flow rotates anticlockwise or clockwise in the first dust cup 301, dust particles in the air flow are pushed outwards by the generated centrifugal force, so that the dust particles move along the inner wall of the first dust cup 301 and enter the second dust cup 302 along the dust guide structure 320 at the position of moving to the public dust guide opening 307, effective separation of the dust particles and the air is achieved, and experiments prove that dust particles remained in the first dust cup 301 can enter the second dust cup 302 under the driving of cyclone air flow. Since the dust particles enter the second dirt cup 302 for the most part, not only is the cyclone chamber 304 in the first dirt cup 301 ensured to be large enough, the resistance of the dust particles in the cyclone chamber 304 to the air flow is reduced, but also the dust particles entering the filter element downstream of the air flow are reduced, and the suction loss is greatly reduced.

As shown in fig. 8 and 9, a first air inlet 306 is provided at an upper portion of the first dust cup 301, and the air inlet passage 303 is connected to the first air inlet 306 through an upper portion of the dust collecting chamber 305. The common dust guide 307 is located in the middle of the common side wall 310, specifically, the common dust guide 307 is located between the first airflow inlet 306 and the bottom of the first dust cup 301. In one possible implementation, the first airflow inlet 306 may be provided at the top of the common side wall 310, and the common dust guide 307 may be provided at the middle of the common side wall 310. The external airflow enters the cyclone chamber 304 from the first airflow inlet 306 at the upper part of the first dust cup 301, primary cyclone separation is performed in the cyclone chamber 304, and dust particles after primary cyclone separation enter the dust collecting chamber of the second dust cup 302 from the public dust guide 307 at the middle part.

The present structural design allows the entire airflow path to be located in the middle of the dirt cup filter 300, which is closer to the motor assembly 200 than the lower inlet air, shortening the airflow path length and reducing the suction loss. The dust particle outlet is arranged in the middle section of the dust cup filtering device 300, the dust particle outlet is arranged at the bottom of the cyclone chamber 304 to prevent the dust particles from whirling, the dust particle outlet is arranged at the top of the cyclone chamber 304 to prevent heavier dust particles from falling off from the first dust cup 301 and failing to enter the second dust cup 302, so that the dust particles can be more effectively collected, more space is further reserved for the cyclone chamber 304, cyclone effect is improved, and suction loss is reduced.

The present disclosure also improves space utilization through the rational layout of the first dirt cup 301 and the second dirt cup 302.
