[0030] The technical solution of the present invention has the following advantages:

[0031] 1. The hand-held cleaner provided by the present invention can perform primary separation on the dirt sucked into the housing by the suction rod through the primary separation module, so that particulate matter and part of the liquid are retained in the primary separation module. A water-vapor separation module is connected to the outlet end of the primary separation module. Through the water-vapor separation module, the liquid sucked into the water-vapor separation module can be intercepted, so that this part of the liquid continues to be retained in the water-vapor separation module, and the gas is discharged.

[0032] 2. In the hand-held cleaner provided by the present invention, the windward plate is arranged opposite to the outlet of the suction rod along the air inlet direction, so that the dirt entering from the suction rod first hits the windward plate. Then, after rebounding, most of the dirt is intercepted in the primary separation module, and the air and a small amount of liquid will further bypass the windward plate and pass through the filter screen under the action of suction, so as to enter the water-vapor separation module.

[0033] 3. In the hand-held cleaner provided by the present invention, the projection of the filter screen along the air inlet direction covers the area where the diversion channel is located, so that the dirt or air must pass through the filter screen before entering the water-vapor separation module, ensuring that solid dirt cannot enter the water-vapor separation module, and only part of the liquid can enter.

[0034] 4. In the hand-held cleaner provided by the present invention, water-vapor diversion holes are provided on the side wall of the separation cover, and the diversion baffle is correspondingly arranged with the water-vapor diversion holes. The diversion baffle can throw the liquid out of the water-vapor diversion holes during the rotation around the axis, so as to perform secondary interception on the liquid and ensure that the air entering the motor is in a dry state.

[0049] Embodiment 1

[0050] Combination Figures 1 - 4 As shown, the handheld cleaner provided in this embodiment includes:

[0051] A housing 60;

[0052] A suction rod 10, which is internally communicated with the housing 60;

[0053] A motor 40, which is arranged in the housing 60 and is adapted to generate negative pressure suction;

[0054] A primary separation module 20, whose inlet end is connected to the suction rod 10, and a filter screen is arranged in the primary separation module 20, which is adapted to perform primary separation on dirt;

[0055] A water-gas separation module 30, which is communicated with the outlet end of the primary separation module 20 and is adapted to intercept liquid and discharge gas.

[0056] Preferably, the suction rod 10 is configured as a hollow rod-shaped structure, one end of which is communicated with the housing 60, and the suction rod 10 is adapted to suck air or dirt into the housing 60 from the other end under the action of the negative pressure suction generated by the motor 40.

[0057] The primary separation module 20 is arranged in the housing 60, or the primary separation module 20 is detachably connected to the housing 60. The inlet end of the primary separation module 20 is connected to the suction rod 10, and the dirt sucked by the suction rod 10 first enters the primary separation module 20. A filter screen is arranged in the primary separation module 20. The filter screen can intercept solid dirt in the primary separation module 20 and can intercept a part of the liquid in the primary separation module 20. Another part of the liquid will pass through the filter screen along with the air flow and enter the water-gas separation module 30.

[0058] Preferably, the filter screen includes: a first filter screen 22 and a second filter screen 23, and the first filter screen 22 and the second filter screen 23 are arranged in a stacked manner. In one implementation form, the first filter screen 22 is made of a metal material or a plastic material, and is provided with a fine mesh structure thereon, which can intercept dirt larger than the mesh diameter; the second filter screen 23 is made of a sponge material, which can further intercept dirt such as particulate matter and dust. However, the second filter screen 23 cannot completely intercept the liquid, and still part of the liquid will pass through the second filter screen 23 and enter the water-gas separation module 30.

[0059] Preferably, a separation cover 32 and a diversion baffle 33 are arranged in the water-air separation module 30, which can further separate the liquid entering the water-air separation module 30, so that the air discharged from the water-air separation module 30 contains as little liquid as possible or no liquid.

[0060] The hand-held cleaner provided in this embodiment can be used to clean small areas of dirty stains with liquid, such as the soup splashed on the tabletop, etc. Through the primary separation module 20 and the water-air separation module 30 provided, solid dirt can be intercepted, and at the same time, the liquid dirt is subjected to two water-air separations. When the liquid dirt passes through the primary separation module 20, most of the liquid can be intercepted, and a small part of the liquid enters the water-air separation module 30 under the action of suction. The water-air separation module 30 further intercepts the liquid, and the separated gas is discharged outside the housing 60 by the motor after secondary filtration.

[0061] The hand-held cleaner provided in this embodiment can perform primary separation on the dirt sucked into the housing 60 by the suction rod 10 through the primary separation module 20, so that the particulate matter and part of the liquid are retained in the primary separation module 20. A water-air separation module 30 is connected to the outlet end of the primary separation module 20. Through the water-air separation module 30, the liquid sucked into the water-air separation module 30 can be intercepted, so that this part of the liquid continues to be retained in the water-air separation module 30, and the gas is discharged. Through two-stage separation, the liquid can be retained in the primary separation module 20 and the water-air separation module 30, and will not enter the motor, thus ensuring the safe operation of the motor and achieving the purpose of cleaning the dirty stains with liquid.

[0062] Preferably, the suction head of the suction rod 10 can have various selection forms. For example, a suction head with a roller brush that can be used for dragging suction, a suction head with a brush that can be used for sweeping suction, a suction head that can scrub while sucking, and so on.

[0063] Preferably, when the primary separation module 20 is detachably connected to the housing 60, the primary separation module 20 can be detached by rotating a certain angle. At the same time, the filter screen can be taken out for rinsing, the collected particulate debris can be poured out, and after rinsing, it can be rotated and reinstalled, and can be used repeatedly for multiple cycles.

[0064] Specifically, the primary separation module 20 includes: a windward plate 21, which is arranged opposite to the outlet of the suction rod 10 along the air inlet direction;

[0065] The windward plate 21 is adapted to separate the filter screen and the suction rod 10 along the air inlet direction.

[0066] The hand-held cleaner provided in this embodiment has the windward plate 21 disposed opposite to the outlet of the suction rod 10 along the air inlet direction, such that the dirt entering from the suction rod 10 first impacts on the windward plate 21. Then, after rebounding, most of the dirt is intercepted within the primary separation module 20, while the air and a small amount of liquid will, under the action of suction, further bypass the windward plate 21 and pass through the filter screen, thereby entering the water-air separation module 30.

[0067] Specifically, the primary separation module 20 further includes:

[0068] A diversion unit 24 is disposed at one end of the filter screen facing away from the windward plate 21, and a diversion channel 241 suitable for liquid flow is provided on the diversion unit 24;

[0069] The projection of the filter screen along the air inlet direction covers the area where the diversion channel 241 is located.

[0070] The diversion unit 24 is disposed at one end of the filter screen facing away from the windward plate 21, and a diversion channel 241 suitable for liquid flow is provided on the diversion unit 24, thereby connecting the primary separation module 20 and the water-air separation module 30 through the diversion unit 24.

[0071] For the hand-held cleaner provided in this embodiment, the projection of the filter screen along the air inlet direction covers the area where the diversion channel 241 is located, such that before the dirt or air enters the water-air separation module 30, it must first pass through the filter screen, ensuring that solid dirt cannot enter the water-air separation module 30, and only a part of the liquid can enter.

[0072] Preferably, a retaining ring is further provided between the primary separation module 20 and the water-air separation module 30. The retaining ring is preferably disposed on the outer peripheral side of the diversion unit 24, such that the liquid dirt can only enter the water-air separation module 30 through the diversion channel 241 and cannot enter through other areas; meanwhile, the sealing effect can be ensured, and dirt leakage to the external environment can be avoided.

[0073] Specifically, the primary separation module 20 further includes:

[0074] A dirt collection box 25 is connected to the suction rod 10. A retaining structure is formed by the convex connection part between the dirt collection box 25 and the suction rod 10, and the retaining structure is suitable for preventing the dirt from entering the suction rod 10 in the reverse direction along the air inlet direction.

[0075] The dirt collection box 25 can collect the dirt intercepted by the filter screen. Meanwhile, a retaining structure is formed by the convex connection part between the dirt collection box 25 and the suction rod 10, and the retaining structure is suitable for preventing the dirt from entering the suction rod 10 in the reverse direction along the air inlet direction, thereby avoiding the dirt from returning to the external environment and ensuring the cleaning effect.

[0076] Specifically, the water-vapor separation module 30 includes:

[0077] A separation cover 32, a water-vapor inlet 321 is provided at a first end of the separation cover 32 along the air inlet direction, and the water-vapor inlet 321 is communicated with at least a part of the diversion channel 241; an exhaust outlet is provided at a second end of the separation cover 32 along the air inlet direction.

[0078] A water-vapor diversion hole 322 is provided on the side wall of the separation cover 32, and the water-vapor diversion hole 322 is adapted to discharge the liquid to the outside of the separation cover 32.

[0079] Preferably, the separation cover 32 is configured as a rotating body structure formed around a central axis.

[0080] Specifically, the water-vapor separation module 30 further includes:

[0081] A diversion baffle 33, the diversion baffle 33 is disposed opposite to the water-vapor inlet 321, and the projection of the water-vapor inlet 321 along the air inlet direction falls within the coverage of the diversion baffle 33;

[0082] The diversion baffle 33 is correspondingly disposed with the water-vapor diversion hole 322, and the diversion baffle 33 is adapted to throw the liquid out of the water-vapor diversion hole 322 during the rotation around the axis.

[0083] Preferably, the water-vapor inlet 321 is configured as a reduced opening structure relative to other parts of the separation cover 32. On the one hand, it can reduce the probability of liquid entering the separation cover 32 as much as possible while ensuring smooth air inlet. On the other hand, when the water-vapor inlet 321 cooperates with the diversion baffle 33, it can ensure that the projection of the water-vapor inlet 321 falls within the coverage of the diversion baffle 33, so that the liquid is completely intercepted by the diversion baffle 33.

[0084] Preferably, the diversion baffle 33 is connected to the motor shaft 41 of the motor 40, and can be rotated by the drive of the motor shaft; a water-vapor diversion hole 322 is provided on the side wall of the separation cover 32, and the diversion baffle 33 is correspondingly disposed with the water-vapor diversion hole 322. The diversion baffle 33 can throw the liquid out of the water-vapor diversion hole 322 during the rotation around the axis, so as to perform secondary interception of the liquid and ensure that the air entering the motor is in a dry state.

[0085] Preferably, the diversion baffle 33 is configured as a bowl-shaped structure, with a concave middle part and a raised edge, so as to facilitate the collection of liquid and prevent the liquid from flowing to the exhaust outlet on the back side of the diversion baffle 33.

[0086] Preferably, a gap is provided between the circumferential edge of the diversion baffle 33 and the inner wall of the separation cover 32. Thus, the diversion baffle 33 intercepts most of the liquid, while the gas can pass through the gap, reducing the probability of the liquid flowing from the gap to the exhaust outlet.

[0087] Specifically, the water-gas separation module 30 further includes: a water collection box 31, which is arranged outside the separation cover 32 and is adapted to collect the liquid discharged from the water-gas diversion holes 322.

[0088] Preferably, a scale mark is provided on the water collection box 31. The sewage is collected in the water collection box 31. When the sewage reaches a certain warning line scale, it will remind the user to pour out the dirty water in the water collection box 31.

[0089] Preferably, the water collection box 31 is detachably connected to the housing 60 and can be opened and installed by rotating a certain angle, which is convenient for flushing the water collection box 31.

[0090] Specifically, the water-gas separation module 30 further includes:

[0091] An exhaust filter screen 34, which is arranged in the separation cover 32, and the exhaust filter screen 34 is arranged on the side away from the water-gas inlet 321 with respect to the diversion baffle 33.

[0092] The exhaust filter screen 34 serves as the last filtering structure, which can intercept the remaining fine liquid and allow the air to pass through the exhaust filter screen 34, ensuring the cleanliness of the air entering the motor 40.

[0093] A motor shaft through hole 341 is formed on the exhaust filter screen 34, which facilitates the motor shaft 41 to pass through the motor shaft through hole 341 and be connected to the diversion baffle 33.

[0094] Specifically, the water-gas separation module 30 further includes:

[0096] Exhaust holes 351 are provided on the sealing ring 35, and the exhaust holes 351 are communicated with the exhaust filter screen 34.

[0097] The exhaust holes 351 are arranged facing the exhaust filter screen 34, so that the air filtered by the exhaust filter screen 34 passes through the exhaust holes 351 and enters the motor 40.

[0098] The other areas of the sealing ring 35 are connected to the housing, which can ensure the sealing effect and prevent the liquid from entering the motor 40 from other areas.

[0099] Specifically, the handheld cleaner further includes: an exhaust slot 61 disposed on the housing 60, and the exhaust slot 61 is adapted to discharge the air sucked by the suction rod 10.

[0100] The air that has passed through the primary separation module 20 and the water-air separation module 30 is discharged from the exhaust slot 61 to ensure smooth ventilation.

[0101] Preferably, the handheld cleaner further includes a battery 50 that can provide electrical energy for the operation of the handheld cleaner.

[0102] Obviously, the above embodiments are merely examples for clear illustration and are not limitations on the implementation manners.
