In this embodiment, a power cord is provided to connect the impeller drive motor 513 and the brushroll drive motor 217, and the power cord may extend from the handle of the body housing 100 to allow the plug of the power cord 106 to engage a power jack for power.

In the illustrated embodiment, the control means may be provided on the grip 101 of the body housing 100 with the control knob 105 of the control means located on the upper side of the front end of the grip 101 so that the user can conveniently operate the control knob 105 by moving the thumb in a state of holding the grip 101. In addition, the operating handle 604 of the fluid delivery device 600 may be disposed below the front end of the handle 101, and the user may conveniently control the cleaning liquid to be sprayed outward by hooking the operating handle 604 with the index finger in a state of holding the handle 101.

In the cleaning machine provided by the embodiment, the water-air separation device 500 is arranged at the front side of the handle 101, the recovery device 300 is connected with the rear side of the handle 101, and the front side of the handle 101 is closer to the center of gravity of the cleaning machine than the rear side of the handle 101. The front side of the fluid delivery device 600 is adjacent to the nozzle device 200 and the back side of the fluid delivery device 600 is adjacent to the front side of the handle 101. At the front side of the cleaning machine, the liquid storage tank 602, the suction nozzle device 200 and the water-gas separation device 500 are distributed in a triangular shape, the liquid storage tank 602, the suction nozzle device 200 and the water-gas separation device 500 are parts with larger mass, the triangular layout enables the structure to be compact as a whole, the size of the cleaning machine is reduced, and meanwhile, the gravity center of the cleaning machine is ensured to be concentrated at the front side of the whole machine. This embodiment makes the holistic focus of cleaning machine lean on before through to each parts of cleaning machine rationally distributed, and when the handheld cleaning machine of user was treated clean the surface, only need exert less power and can make suction opening 205 contact treat clean the surface, and the operation is more laborsaving.

Further, the suction nozzle unit 200, the deflector 400, and the recovery unit 300 are arranged in a straight line along the length direction of the washing machine. The bottom surface of the body housing 100 forms an angle with the bottom surface of the recovery device 300 and the bottom surface of the suction nozzle device 200, respectively, and when the cleaning machine is supported on a support surface by the bottom surface of the body housing 100, the bottom surface of the recovery device 300 and the bottom surface of the suction nozzle device 200 are both located away from the support surface. Specifically, the included angle between the bottom surface of the machine body casing 100 and the bottom surface of the recovery device 300 is 5 to 25 °. The included angle between the bottom surface of the body housing 100 and the bottom surface of the suction nozzle device 200 is 15-40 deg. The structure design reduces the contact area between the bottom surface and the supporting surface of the cleaning machine, thereby saving labor in operation, and the design that the suction nozzle device and the recovery device are inclined towards two sides can keep the machine body balanced, can also lead the suction nozzle to be ventilated and dried, and avoids the generation of peculiar smell in the fluid channel inside the cleaning machine.

Variations in the mass of the liquid in the tank 602 and the sump 301 affect the centre of gravity of the washing machine. Specifically, when the recovery device 300 does not store liquid, the center of gravity of the cleaning machine is located at the water-gas separation device 500; as the volume of the liquid stored in the recovery device 300 increases, the center of gravity of the washer moves from the water and air separating device 500 to the front side of the handle 101. When the tank 602 containing the fluid is mounted to the fluid delivery device docking portion 102, the center of gravity of the washer moves along the direction of extension of the tank 602 to the water-gas separation device 500 as the washer uses less fluid in the tank 602.

In a use situation, when the user holds the handle 101, uses the washing machine, or takes the washing machine, the center of gravity of the washing machine is located between the holding portion of the handle 101 and the nozzle device 200. As the volume of the liquid stored in the recovery device 300 increases, the center of gravity of the cleaning machine moves toward the grip portion of the handle 101.

The cleaning machine that this embodiment provided sets up water and gas separator in the handle front side, and recovery unit sets up in the handle rear side, can make the cleaning machine naturally lean forward when the guarantee cleaning machine grips the equilibrium, both can ensure the vacuum of front end suction nozzle device suction inlet, makes the cleaning machine use the operation more laborsaving again. In addition, because the recovery device is arranged behind, the design of the recovery device is less limited, and the sewage storage capacity of the recovery device is increased.

With reference to fig. 26-27, the operation of the washer is as follows:

a user holds the handle 101 of the cleaning machine, places a thumb on the control button 105 on the handle 101, hooks the operating handle 604 with the index finger and/or the middle finger, applies force to the operating handle 604 through the index finger and/or the middle finger to enable the operating handle 604 to be close to the handle 101, rotates the connecting end 636 of the operating handle 604 by taking the abutting shaft 635 as a fulcrum to squeeze the operating rod 609, enables the front end of the operating rod to be pushed towards the interior of the pump shell 608, squeezes cleaning liquid in the pump, and enables the cleaning liquid to be sprayed on a cleaning surface from the spray head 601. A suction opening 205 of the cleaning machine is moved to a cleaning surface, a control button 105 is pressed to start an impeller driving motor 513 and a brush roll driving motor 217, the impeller driving motor 513 drives an impeller 512 to rotate, so that a fluid channel formed by sequentially connecting the suction opening 205, an air guide pipe 204, an air inlet channel 401, an air inlet pipe 302, an air outlet pipe 303, a dirt storage cavity 304, an air return channel 402, a separation cavity 509, an isolation cavity 506 and an air outlet 325 generates negative pressure, liquid and debris near the suction opening 205 are sucked into the suction opening 205 together with air, the brush roll driving motor 217 drives a brush roll 215 to rotate, and scraping blades and/or bristles on the brush roll 215 stir the surface to be cleaned, so that the liquid and the debris on the cleaning surface are sucked into the suction opening 205 more easily.

After entering the suction port 205, the fluid with the liquid and debris passes through the air guide pipe 204, the air inlet channel 401 and the air inlet pipe 302 in sequence and reaches the dirt storage tank 301, most of the liquid and debris are deposited at the lower part of the dirt storage tank 301, and the first water-air separation is completed. The separated fluid sequentially passes through the air outlet pipe 303 and the air return channel 402 to enter the separation cavity 509, under the action of centrifugal force generated by rotation of the impeller 512, liquid in the fluid is thrown onto the inner wall of the shell, and flows into the flow guide groove 537 along the inner wall of the shell 501, enters the air inlet channel 401 through the water return pipe communicated with the flow guide groove 537, and is sucked into the dirt storage cavity 304 again to complete secondary water-gas separation. The separated fluid further passes through the partition 503, the isolation cavity 506, the wind shielding mechanism 508, the shell air outlet 507 and the shell air outlet 104 and is discharged out of the cleaning machine, and in the process, the fluid is blocked by the partition 503, the inner wall of the isolation cavity 506 and the wind shielding mechanism 508, so that liquid in the fluid is condensed on the partition 503, the inner wall of the isolation cavity 506 and the wind shielding mechanism 508 and further converged into the flow guide groove 537 in the separation cavity 509 and enters the air inlet channel 401 along the water return pipe, and the third water-gas separation is completed. In the embodiment, the water-gas separation effect is improved through the water-gas separation for three times, so that the liquid content in the fluid discharged from the cleaning machine is greatly reduced.

When the cleaning machine of the embodiment is used on an inclined plane, the liquid in the dirt storage tank 301 may be concentrated at the front, the rear, the upper part or even the lower part of the dirt storage tank 301, and because the outlet of the air inlet pipe 302 and the inlet of the air inlet pipe 303 are both positioned in the middle upper region of the dirt storage tank 301 and keep a certain distance from each inner wall of the dirt storage tank 301, the cleaning machine can be used at any angle without the liquid in the dirt storage tank 301 easily entering the air inlet pipe 302 or the air outlet pipe 303, which is beneficial to reducing the accumulated liquid in the separation cavity 509 and the isolation cavity 506 and improving the safety of the impeller driving motor 513. Further, even if the liquid content of the fluid in the separation chamber and the isolation chamber is large or water is accumulated for a short time, the impeller driving motor 513 can be prevented from entering water because the electrified parts on the impeller driving motor 513 and the impeller 512 are subjected to waterproof treatment. In addition, by arranging a plurality of water return holes in the flow guide groove 537 in the circumferential direction, when the cleaning machine is used in different inclined angles, the liquid in the flow guide groove 537 can be guided into the air intake channel 401.

After the washing is completed, the impeller drive motor 513 and the brush roller drive motor 217 are stopped by pressing the control button 105. The recovery device 300 is detached from the cleaning machine, the drain plug 317 is pulled out, and the liquid in the dirt storage tank 301 is poured out to complete the dirt disposal.
