Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, and particularly relates to a fabric cleaning machine with a gas-liquid separation function. Background Art

[0002] A handheld cleaning machine can clean fabric products such as carpets, fabric sofas, and curtains. Its cleaning process is usually to spray a cleaning liquid or clean water containing a cleaning agent onto the surface of the fabric product. After the surface of the fabric product is wetted, the user starts the negative pressure component, and the suction port of the fabric cleaning machine absorbs the water stains and dirt on the surface of the fabric product into the sewage tank. The gas-liquid separator in the sewage tank separates the sewage and gas, so that the sewage stays in the sewage tank and the gas is discharged to realize the cleaning and sewage collection process; however, during the use of the existing fabric cleaning machine, due to incomplete gas-liquid separation, part of the sewage will enter the motor component along with the gas, causing damage to the motor component, and there is room for improvement. Summary of the Utility Model

[0003] The utility model aims to overcome the above-mentioned defects in the prior art and provides a fabric cleaning machine with a gas-liquid separation function. Through the guiding action of the outlet section of the air inlet channel, the inhaled air flow can directly impact the top wall of the sewage tank, and the liquid therein can flow down along the flow plate to realize preliminary gas-liquid separation; then the air flow passes through the gas-liquid separation box in front of the output port and realizes secondary gas-liquid separation under the action of the zigzag channel in the gas-liquid separation box, thereby realizing complete gas-liquid separation and effectively ensuring the stability of the operation of the motor component.

[0004] To achieve the above object, the utility model provides a fabric cleaning machine with a gas-liquid separation function, including:

Detailed implementation

[0021] The following combines the drawings to describe in detail a specific implementation of the present utility model, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation.

[0022] A fabric cleaning machine with a gas-liquid separation function according to the present utility model is as Figure 1 and Figure 2 shown, including a main body 10 and a sewage tank 20 detachably installed on the main body 10; an installation notch 11 is provided on the corresponding lateral side of the main body 10, and the installation notch 11 includes a support wall that cooperates with the sewage tank 20, and an air inlet 12 and an air outlet 13 are longitudinally spaced at the upper end of the support wall. An operating handle 15 is connected to the main body 10 and a motor assembly is arranged inside it. An air inlet channel 14 is constructed between the connection port of the operating handle 15 and the air inlet 12 inside the main body 10, and an air outlet channel is constructed between the inlet of the motor assembly and the air outlet 13 inside it; the sewage tank 20 is embedded in the installation notch 11 of the main body 10. The sewage tank 20 has a mating wall that fits with the support wall, and an input port 31 and an output port 32 that are respectively docked and communicated with the air inlet 12 and the air outlet 13 are provided on the mating wall. A gas-liquid separation structure is also arranged in the sewage tank 20. In this way, when the motor assembly of the main body 10 works, suction can be generated at the operating handle 15 to suck the dirt on the surface to be cleaned into the sewage tank 20, and the suction air flow with dirt is subjected to gas-liquid separation under the action of the gas-liquid separation structure in the sewage tank 20 to isolate the dirt in the sewage tank 20.

[0023] In this embodiment, a primary gas-liquid separation structure is provided in front of the input port 31 in the sewage tank 20, and a secondary gas-liquid separation structure is provided in front of the output port 32. In this way, complete gas-liquid separation can be achieved through secondary separation, effectively avoiding water vapor from entering the motor and ensuring the stability of the motor operation.

[0024] Specifically as Figure 1 and Figure 3As shown, a horizontally extending baffle 433 is provided between the input port 31 and the output port 32 corresponding to the sewage tank 20. This baffle 433 is used to divide the inner cavity of the sewage tank 20 so that the air flow flowing in from the input port 31 needs to bypass the baffle 433 before flowing out from the output port 32. The air inlet passage 14 includes an outlet section 141 that is connected to the air inlet 12 and extends obliquely upward. A flow-along plate 42 is provided in front of the projection area where the top wall of the sewage tank 20 extends corresponding to the outlet section 141. In this way, the inhaled air flow can directly impact the top wall of the sewage tank 20 under the guiding action of the outlet section 141, and the liquid therein will flow down along the flow-along plate 42 to achieve preliminary gas-liquid separation. Preferably, the wall surface within the projection area where the top wall of the sewage tank 20 extends corresponding to the outlet section 141 is an arc surface structure or an inclined surface structure suitable for guiding the fluid flow towards the flow-along plate 42. In this way, the preliminarily separated liquid can flow down along the flow-along plate 42 better.

[0025] Specifically, as Figure 3 and Figure 4 shown, a gas-liquid separation box 43 is provided in front of the output port 32 corresponding to the sewage tank 20. A guide outlet 432 is provided on the rear wall of the gas-liquid separation box 43 opposite to the mating wall, and a guide inlet 431 is provided on its front wall. At the same time, at least one baffle 433 is also provided in the gas-liquid separation box 43 so that a zigzag channel is formed between the guide inlet 431 and the guide outlet 432 in the box. In this way, the air flow flows in a zigzag manner in the gas-liquid separation box 43 and continuously hits the wall to achieve secondary gas-liquid separation. Preferably, the openings formed by the zigzag channel corresponding to the flow direction on the gas-liquid separation box 43 are arranged in a vertically offset manner. In this way, a zigzag flow is also formed in the vertical direction, which can further improve the gas-liquid separation effect. At the same time, the guide inlet 431 is preferably arranged at the upper end of the front wall of the gas-liquid separation box 43. Preferably, a baffle 44 extending longitudinally and connected to the partition plate 41 is provided in front of the gas-liquid separation box 43 on the top wall of the sewage tank 20. The lower end of the baffle 44 extends below the lower edge of the guide inlet 431. At the same time, preferably, the lower end of the partition plate 41 is lower than the lower end of the flow-along plate 42, and the lower end of the flow-along plate 42 is lower than the lower end of the baffle 44.

[0026] In this embodiment, as Figure 3 shown, the sewage tank 20 includes a box body 30 with an open upper end and a top cover 40 covering the upper port of the box body 30. The partition plate 41, the gas-liquid separation box 43, the flow-along plate 42, and the baffle 44 are all provided on the top cover 40. First ribs 33 and second ribs 34 that cooperate with the partition plate 41 and the gas-liquid separation box 43 are respectively provided on the mating wall of the box body 30. In this way, by engaging and connecting the first ribs 33 with the partition plate 41, it can be avoided that the air flow directly flows through the gap between the partition plate 41 and the mating wall. At the same time, by engaging and connecting the gas-liquid separation box 43 with the second ribs 34, it can be avoided that the air flow directly flows through the gap between the gas-liquid separation box 43 and the mating plate.

[0027] Compared with the prior art, the utility model has a simple and reasonable structure. Through the guiding effect of the outlet section of the air inlet channel, the inhaled air flow can directly impact on the top wall of the sewage tank, and the liquid therein can flow down along the flow plate, thus realizing preliminary gas-liquid separation. Then, the air flow passes through the gas-liquid separation box in front of the output port and realizes secondary gas-liquid separation under the action of the folded line channel in the gas-liquid separation box, so as to realize the complete separation of gas and liquid under the action of secondary separation, avoid water vapor from entering the motor assembly, and ensure the stability of the operation of the motor assembly.

[0028] The above only discloses the embodiments of the utility model. However, the utility model is not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the utility model.
