[0022] See Figure 1 , which shows a schematic example of a cleaning device. The cleaning device 100 is suitable for cleaning soft material surfaces such as sofas and carpets. The cleaning device 100 includes a horizontal main body 1, a cleaning head 2, and a flexible tube assembly 3 provided between the horizontal main body 1 and the cleaning head 2.

[0023] The horizontal main body 1 can be supported on a plane and is configured to be carried by an operator as needed. The horizontal main body 1 includes a horizontal housing 11 that can be supported on a plane, and multiple components are supported on the horizontal housing 11, such as a fluid delivery system and a recovery system; the fluid delivery system is used to deliver cleaning fluid to the surface to be cleaned, and the recovery system is used to recover fluid and debris from the surface to be cleaned and store the recovered fluid and debris.

[0024] The cleaning head 2 is configured as a cleaning head that can be held by the user so that it can be moved along the surface to be cleaned under the carrying of the operator.

[0025] The cleaning head 2 is attached to one end of the flexible tube assembly 3, and the other end of the flexible tube assembly 3 is connected to the horizontal housing of the horizontal main body 1.

[0026] See Figure 2 , the fluid delivery system includes a liquid supply tank 4 for storing liquid and a pump mechanism 5 that is in fluid communication with the liquid supply tank 4. The liquid stored in the liquid supply tank 4 may include, but is not limited to, water, a solution including water and a cleaning agent. The pump mechanism 5 can continuously output the liquid in the liquid supply tank 4 during operation.

[0027] In some embodiments, the fluid delivery system may also optionally be configured with a steam boiler for heating the liquid from the liquid supply tank into a hot fluid or steam for external output. The steam boiler should generally be arranged downstream of the pump mechanism.

[0028] The recovery system includes a recovery tank 6 and a suction motor assembly 7 that is in fluid communication with the recovery tank 6. The suction motor assembly 7 includes a suction end 71 and an exhaust end 72. The suction motor assembly 7 can generate suction power to send the waste liquid and debris from the surface to be cleaned together with air to the recovery tank 6. The waste liquid and debris will remain at the recovery tank 6, and the air will flow from the suction end 71 of the suction motor assembly 7 to the exhaust end 72 and be discharged. The core components of the suction motor assembly 7 include a motor and an impeller component that can be driven by the motor to rotate. Since the suction motor assembly is a relatively common component in a suction cleaning device, it will not be described in detail here.

[0029] The cleaning head 2 includes a suction nozzle 21, a nozzle 22, and a cleaning element 23 for friction with the surface to be cleaned. The suction nozzle 21 is in fluid communication with the recovery tank 6 through a recovery pipeline 31 in the flexible pipe assembly 3. The nozzle 22 is in fluid communication with the liquid outlet of the pump mechanism 5 through another liquid delivery pipeline 32 in the flexible pipe assembly 3.

[0030] See Figures 3-4 As shown, the pump mechanism 5 is a pneumatic pump water assembly, which is composed of a pneumatic part 501 and a water pump part 502.

[0031] The pump mechanism 5 includes a housing assembly 51. The housing assembly 51 includes a first housing 511 that defines the pneumatic part 501 and a second housing 512 that defines the water pump part 502. The first housing 511 and the second housing 512 are fixed to each other by a fixing seat 52.

[0032] As Figure 4 , Figure 5As shown, there is a first chamber 53 inside the first housing 511. The first housing 511 is also provided with an air inlet 531 and an air outlet 532 that are in fluid communication with the first chamber 53. In this embodiment, the first housing 511 is composed of a first housing member 5111 and a second housing member 5112. Among them, both the air inlet 531 and the air outlet 532 are formed on the first housing member 5111. A second chamber 54 is defined inside the second housing 512. The second housing 512 is provided with a liquid inlet 541 and a liquid outlet 542 that are in fluid communication with the second chamber 54. In this embodiment, the second housing 512 is composed of a third housing member 5121 and a fourth housing member 5122. Among them, both the liquid inlet 541 and the liquid outlet 542 are formed on the third housing member 5121. The first chamber 53 and the second chamber 54 will be isolated from each other.

[0033] The pump mechanism 5 includes a rotating shaft 55, and the rotating shaft 55 is rotatably supported on the first housing 511 and the second housing 512. The rotating shaft 55 extends from the first chamber 53 to the second chamber 54 along the axis X direction, that is, the rotating shaft 55 penetrates into the first chamber 53 and the second chamber 54 at the same time.

[0034] The pump mechanism 5 includes a pneumatic impeller 56. The pneumatic impeller 56 is arranged in the first chamber 53 and supported on the rotating shaft 55. The pneumatic impeller 56 is configured to be driven by the wind blown into the first chamber 53 through the air inlet 531 to drive the rotating shaft 55 to rotate together around an axis X. In this example, the pneumatic impeller 56 includes a first impeller member 561 and a second impeller member 562. As Figure 4 shown, both the first impeller member 561 and the second impeller 562 are fixedly supported on the rotating shaft 55 and are axially opposite to each other. The first impeller member 561 and the second impeller 562 will jointly define a plurality of air ducts 563 distributed circumferentially. In order to enable all the air entering the first chamber 53 to flow along the air inlet 531, a plurality of air ducts 563 and the air outlet 532, a pair of seals 564 are arranged in the first chamber 53; as Figure 5 shown, a pair of seals 564 are respectively arranged at the two rotating supports of the rotating shaft 55 and the first housing 511, and the pair of seals 564 can prevent air from escaping through the two rotating supports of the rotating shaft 55 and the first housing 511.

[0035] The pump mechanism 5 further includes a water pump impeller 57. The water pump impeller 57 is arranged in the second chamber 54 and is simultaneously fixedly supported on the rotating shaft 55. When the water pump impeller 57 is driven to rotate, a flow power will be generated to make the liquid flow from the liquid inlet 541 to the liquid outlet 542. A sealing ring 572 and a seal 573 are arranged in the second chamber 54, and the sealing ring 572 and the seal 573 can effectively prevent the fluid flowing into the second chamber 54 from leaking. A limiting member 574 is also arranged in the second chamber 54, which can effectively prevent the water pump impeller 57 from generating axial displacement.

[0036] Continue as Figure 2 shown, the air inlet 531 is in fluid communication with the exhaust end 72 of the suction motor assembly 7, and the air outlet 532 is in communication with the outside atmosphere; in this way, the air discharged from the exhaust end 72 will be introduced into the first chamber 53 and drive the pneumatic impeller 56 to rotate, and then be discharged to the outside after doing work. The liquid inlet 541 is in fluid communication with the supply tank 4, and the liquid outlet 542 will be in fluid communication with the liquid delivery pipe in the flexible pipe assembly 3. When the rotating shaft 55 is driven to rotate, the water pump impeller 57 will rotate together, so as to realize the transportation of the liquid in the supply tank 4 to the nozzle 22 of the cleaning head 2.

[0037] In addition, the above pump mechanism can also be used in a push-rod type cleaning device; in the push-rod type cleaning device, the cleaning head is a cleaning head that can be supported on the surface to be cleaned, and the cleaning device further includes: a vertical body, a fluid recovery system and a fluid delivery system are supported on the vertical body, and the lower part of the vertical body is rotatably arranged with the cleaning head; and a handle rod assembly, which is connected to the upper part of the vertical body and includes a handle for the user to hold.

[0038] In this application, the pump mechanism is driven by the discharged air of the suction motor assembly, which can work without electric energy. It not only saves energy, but also reduces the manufacturing cost, and can also be used in horizontal and push-rod type cleaning devices equipped with suction motor assemblies.

[0039] The above shows and describes the basic principles, main features and advantages of this application. Those skilled in the art should understand that this application is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of this application.
