Description

Technical Field

[0001] The present application relates to the field of cleaning technology, and in particular to a portable cleaning device. Background Art

[0002] When cleaning hard surfaces such as glass, various water-absorbing cleaners are often used. This type of cleaner uses a motor to generate suction to suck dust and small water droplets from the hard surface through a suction nozzle, and can absorb the dust and water droplets into a accommodating cavity. For example, Chinese patent document CN103445717B discloses a portable hard surface suction device, which has a suction nozzle, a rotating body, and a separation device. When the air mixture flows onto the rotating body, the liquid rotates with the rotating body and generates centrifugal force. Under the action of this centrifugal force, the liquid enters the water collection container through the gap in the suction channel, while the air is discharged through the suction channel, thereby achieving the separation of liquid and air. In this solution, the structure of the water-gas separation device is complex, and the liquid in the air flow is thrown into the water collection container by rotation. In addition, the capacity utilization rate of the water collection container is not high, and the liquid cannot be effectively thrown into the water collection container.

[0003] Therefore, the existing window washing device needs to be improved. Summary of the Invention

[0040] The above scheme is further described below with reference to specific examples. It should be understood that these examples are intended to illustrate the present application and are not intended to limit the scope of the present application. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer. The implementation conditions not specified are generally those used in routine experiments.

[0041] Unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should have the usual meanings understood by persons with ordinary skills in the field to which this application belongs. "Include" or "including" and other similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and other similar words are not limited to direct physical or mechanical connections, but may be indirect connections. "Up", "down", "left", "right" and the like are only used to indicate relative position relationships. When the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0042] The present application discloses a portable cleaning device, which includes: a main body, one side of which is connected to a suction nozzle assembly, the main body having a cavity therein for accommodating a water collection container, the main body further comprising: a suction pipe, a gas-liquid separation module that also serves as a gravity module, a fan assembly, and a drive motor, wherein the suction pipe and the gas-liquid separation module are located in the cavity of the water collection container, one side end of the suction pipe at least partially passes through the water collection container to connect to the suction duct of the suction nozzle assembly, the other end of the suction pipe is connected to the gas-liquid separation module, the liquid separation module is provided with a protrusion, the protrusion is provided with a water outlet, the liquid separation module is connected to the air outlet pipe, the air outlet pipe is connected to the fan assembly, and the fan assembly is connected to the drive motor. Based on the drive of the drive motor, the gas separated by the gas-liquid separation module is discharged from the air outlet on the main body under the guidance of the fan assembly. The gas-liquid separation module is configured with a gravity module, and due to the effect of the center of gravity, the water outlet will always face downward. In this way, when the window washing device is in operation, the water vapor mixture is sucked in from the suction port and passes through the channel to the gravity module. When the water vapor mixture enters the front channel, it will hit the wall set on the gravity pendulum block. The water vapor condenses into water as a tangible substance. After hitting the wall, it will adhere to the wall and flow into the device through the water outlet along the wall. After passing through the water outlet, the gas will turn and enter the air outlet duct, and then be discharged from the body of the window washing device. With such a design, no matter what the working state is, water will be injected into the dirty water device through the gravity module at the first time to achieve water / vapor separation. Because the gravity pendulum block is placed in the center of the device (in the middle), the window washing device can absorb water to the maximum amount of water marked on the water tank regardless of its working posture. The portable cleaning device is used for washing (glass) windows.

[0043] Next, the portable cleaning device proposed in this application will be described with reference to the accompanying drawings.

[0044] like Figure 1 is a schematic diagram showing the three-dimensional structure of a portable cleaning device according to an embodiment of the present application;

[0045] The window washing device 100 comprises:

[0046] The main body 120 is connected to a nozzle assembly 130 on one side, and a handle 100 is disposed on the side opposite the nozzle assembly 130. A cover 120a is provided on the main body 120. Preferably, the cover 120a is made of a transparent material so that the user can easily check the water collection status. In one embodiment, a graduated scale 120b is provided on the cover 120a to indicate the water level in the water collection container to the user, prompting the user to pour out the water promptly.

[0047] The schematic diagram of the window washing device at one viewing angle is as follows Figure 2 and Figure 3 As shown,

[0048] The nozzle assembly 130 includes a connection portion 131, which is connected to the main body 120. The main body 120 is provided with a drain chute, which is provided with a sealing member 121. The main body 120 is provided with an air outlet 126b and a control module 129 (the control module 129 is a switch / button).

[0049] The following combination Figure 4 To describe the internal structure of the window washing device, Figure 4 for Figure 3 Schematic diagram of the cross section of AA;

[0050] The main body 120 has a cavity 125 for installing a water collection container 140. The main body 120 also has a suction pipe 122, a gas-liquid separation module 123, a fan assembly and a drive motor 127.

[0051] The suction pipe 122 and the gas-liquid separation module 123 are located in the cavity of the water collection container 140.

[0052] One end of the suction pipe 122 at least partially passes through the water collection container 140 and is connected to the suction duct of the suction nozzle assembly 130. The other end of the suction pipe 122 is connected to the gas-liquid separation module 123. The liquid separation module 123 is provided with a water outlet 123a. The gas separated by the liquid separation module 123 enters the air outlet pipe 150. The air outlet pipe 150 is connected to the fan assembly. The gas separated by the liquid separation module 123 is discharged through the guidance of the fan blades 126a of the composite fan 126 of the fan assembly. The fan assembly is connected to the drive motor 127.

[0053] During operation, the window washer device draws a water vapor mixture through the suction port 133 of the suction nozzle 132, passes through the suction pipe 122, and enters the gas-liquid separation module 123. Upon entering the gas-liquid separation module 123, the water vapor encounters the barrier wall 123d provided on the gravity pendulum. The water vapor condenses into tangible water, which adheres to the barrier wall 123d and flows along the barrier wall 123d through the water outlet 123a into the water collection container 140 within the main body 120. The gas then passes through the air outlet 150, the fan, and exits the window washer device through the air outlet 126b. This design utilizes the gravity module within the gas-liquid separation module 123. Due to the swinging action of the gravity module, the water outlet 123a of the gas-liquid separation module 123 always points downward, ensuring rapid outflow of the drawn water into the water collection container, thus achieving rapid water / vapor separation. In this embodiment, the gas-liquid separation module 123 is arranged in the central part (middle) of the main body 120 to maximize the use of the water collection container. In this embodiment, the gas-liquid separation module 123 has a simple structure. Figure 8 As shown:

[0054] The gas-liquid separation module 123 has:

[0055] The first open connection end 123b is rotatably connected to the suction pipe 122.

[0056] The second open connection end 123c is disposed opposite to the first connection end 123b and is used to communicate with the air outlet duct 150.

[0057] The protrusion 124 is located circumferentially outside the gas-liquid separation module 123. This protrusion 124 is provided with a water outlet 123a, which communicates with the first open connection end 123b. (This protrusion 124 is located on one side of the connection end, thus also serving as a gravity module.) In this embodiment, the ratio of the outer diameter of the second open connection end 123c to the outer diameter of the first open connection end 123b is between 1.1 and 1.6. Preferably, the axial projection of the first open connection end 123b lies within the outline of the second open connection end 123c.

[0058] The handle portion 100 is provided with a housing space 111 for accommodating a battery (e.g., a lithium-based battery). A connection portion (not shown) is provided in the housing space 111. The connection portion is connected to a charging terminal 112, through which the battery in the housing space 111 can be charged. Preferably, the handle portion 100 and the main body portion 120 are integrally formed. In one embodiment, the charging terminal 112 is a connection terminal for charging via an external power source. The charging terminal 112 can also be a power receiving module, which is matched with a power transmitting module to achieve wireless charging.

[0059] Next, combine Figure 5-Figure 12 To describe the internal structure of the window washing device in detail,

[0060] The water collection container 140 (see Figure 7 ), is provided with a drain port 142, which is connected to the sewage trough provided on the main body 120, and a cover plate 141, which covers the main body 120.

[0061] The air outlet duct 150 is connected to a composite fan 126, which is equipped with a plurality of blades 126a. The composite fan 126 is connected to a drive motor 127, which is connected to a base 126c. A plurality of spaced protrusions 126d are circumferentially arranged on one side of the base. Driven by the drive motor 127, the composite fan 126 rotates, directing incoming air through the blades and discharging it through the gaps between the protrusions 126d through the air outlet 126b. Preferably, a protective cover 127a is also provided on the outside of the drive motor 127. The gas-liquid mixture flowing from the suction pipe 122 flows into the gas-liquid separation module 123 through the first connection end 123b. Liquid / water molecules condense upon impacting the barrier wall 123d or the barrier wall 123d and the inner wall of the gas-liquid separation module 123. Water, a tangible substance, adheres to the wall upon impact and flows through the water outlet into the water collection container. After exiting through the water outlet, the gas passes through the S- and Z-bends and enters the air outlet duct 150, where it is discharged through the fan through the air outlet 126b. The air outlets 126b are located on both sides of the main body 120 (preferably, symmetrically along the centerline of the main body).

[0062] The main body 120 is equipped with a switch 129, which is electrically connected to a control board 128. The control board 128 is located within the contour of the composite fan 126. In this embodiment, the gas-liquid separation module 123 is rotatably connected to the suction pipe 122. This ensures that the water outlet 123a is always facing downward due to the weight of the module. This ensures that the water in the suctioned water vapor mixture is separated and promptly discharged into the water collection container through the water outlet 123a, regardless of the operating position of the window washer. This simple structure ensures that the water in the suctioned water vapor mixture is separated and promptly discharged into the water collection container through the water outlet 123a.

[0063] The above embodiments are intended only to illustrate the technical concepts and features of this application. Their purpose is to enable those familiar with the art to understand the content of this application and implement it accordingly. They are not intended to limit the scope of protection of this application. Any equivalent changes or modifications made in accordance with the spirit of this application shall be included in the scope of protection of this application.
