Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, and more specifically to a gas-liquid separation component and a cleaning machine. Background Art

[0002] The cleaning products currently on the market, such as floor scrubbers, carpet cleaners, and fabric cleaners, usually contain a large amount of moisture in the airflow generated by the suction of the motor when the machine is working. This moisture can easily enter the internal space of the machine, causing the internal electronic control components of the machine to become damp, affecting the operation of the machine's electronic control system or causing faults such as short circuits in components and burning of circuit boards.

[0003] Therefore, it is necessary to reduce the moisture content in the airflow. For example, Chinese patent No. CN218186628U discloses a fabric cleaning machine with a gas-liquid separation function, which includes: a cleaning machine body, which is provided with a motor cavity and a sewage cavity, the motor cavity is provided with a motor, and the sewage cavity is equipped with a sewage tank; a suction head connecting pipe, which is arranged on the cleaning machine body; a gas-liquid separation component, which includes an air inlet pipe and an air outlet pipe, the air inlet pipe and the air outlet pipe are both arranged in the sewage tank, and the suction head connecting pipe, the air inlet pipe, the air outlet pipe and the motor cavity are connected in sequence; a water level sensing component, which includes a sensing part, a magnetic levitation part and a magnetic levitation channel, the magnetic levitation channel is vertically arranged in the sewage tank, the sensing part is movably arranged in the magnetic levitation channel up and down, and the sensing part is arranged in the motor cavity.

[0004] Although this prior art uses an air-liquid separation component to separate the moisture in the inhaled air flow, it sets the air inlet pipe and the air outlet pipe in the sewage tank, resulting in a small accommodating space for the sewage tank. It is only suitable for cleaning a small area, but not for cleaning a large area such as a carpet or floor. In addition, the prior art has a complex structure. The sewage tank is prone to dirt and grime, and the interior must be equipped with an air inlet pipe, an air outlet pipe and a magnetic levitation channel, which makes cleaning and maintenance inconvenient.

[0033] Reference Figure 1-6 A gas-liquid separation component and a cleaning machine according to an embodiment of the utility model are described.

[0034] In one embodiment, Figure 1-5 As shown, a gas-liquid separation component 100 includes a filter 2, a gas-liquid separator 1 and a sewage collection box 3 connected in sequence from top to bottom, and the gas-liquid separator 1 is equipped with an air inlet pipe 4.

[0035] The air inlet pipe 4 includes a middle section pipe body and an outlet end pipe body and an inlet end pipe body respectively connected to the two ends of the middle section pipe body. The outlet end pipe body is installed at the bottom of the gas-liquid separator 1 and is bent downward so that the outlet of the air inlet pipe 4 faces downward and is located above the sewage collection tank 3. The middle section pipe body is tilted downward to pass through the upper part of the rear wall of the sewage collection tank 3, and the inlet end pipe body is connected to the suction pipe at the bottom of the cleaning machine 200.

[0036] The gas-liquid separator 1 is also provided with an air inlet 5 , which is located higher than the outlet of the air inlet pipe 4 . The air inlet 5 is connected to the motor cavity of the cleaning machine 200 through the filter 2 .

[0037] Among them, the outlet of the air inlet pipe 4 faces downward and is located above the sewage collection tank 3, and the position of the air inlet 5 is higher than the outlet end of the air inlet pipe 4. Since the outlet of the air inlet pipe 4 faces downward and is arranged below the air inlet 5 on the gas-liquid separator 1, moisture and garbage will not be sucked into the air inlet 5, but fall into the sewage collection tank 3 under the action of gravity.

[0038] When implementing it, Figure 3 and Figure 5As shown in the figure, the airflow direction inside the washing machine 200, the suction created by the motor in the washing machine 200 when working generates negative pressure, and the negative pressure generates airflow, and the airflow brings the garbage and moisture on the ground into the sewage collection tank 3 through the air inlet pipe 4. The outlet of the air inlet pipe 4 is downward and located above the sewage collection tank 3. The garbage and moisture in the gas-liquid mixture fall downward into the sewage collection tank 3, and the airflow passes through the air outlet upward into the motor cavity and then discharged out of the machine, which can effectively separate the garbage and moisture in the airflow / can effectively separate the garbage and moisture in the airflow into the sewage collection tank 3, preventing the garbage and moisture from entering the machine with the airflow.

[0039] At the same time, the air inlet 5 is arranged above the sewage collection tank 3, which can effectively prevent the sewage in the sewage collection tank 3 from flowing back into the machine during the use of the machine.

[0042] In this embodiment, a grid is provided on the air inlet 5 to further prevent garbage particles from passing through.

[0043] The grid of the air inlet 5 may be a cross-shaped grid, which not only prevents garbage particles from passing through, but also can reinforce the structure of the air inlet 5 to make it more stable.

[0044] In this embodiment, a receiving cavity 11 is provided on the top surface of the shell, and the filter 2 is placed in the receiving cavity 11, which facilitates the installation and replacement of the filter 2 and reduces the space occupied by the gas-liquid separation component 100, making the component structure more compact.

It further filters the airflow that has undergone gas-liquid separation treatment, removes dust particles that have not fallen into the sewage collection box 3, prevents dust from entering the motor cavity, and ensures the safe operation of the cleaning machine 200.

[0046] Among them, HEPA is a high efficiency particulate air filter with very high filtration accuracy, which can filter particles of 0.1 microns and 0.3 microns.

[0047] In this embodiment, by using a HEPA filter with high filtration accuracy to filter the airflow that has undergone gas-liquid separation treatment, dust can be prevented from entering the motor cavity, thereby ensuring the safe operation of the cleaning machine 200.

[0048] In this embodiment, a partition 12 is provided between the outlet of the air intake pipe 4 and the air intake port 5 . The partition 12 is vertically installed on the bottom surface of the base plate to separate the outlet of the air intake pipe 4 from the air intake port 5 to prevent garbage and moisture from entering the air intake port 5 .

[0049] In this embodiment, the partition plate 12 is an integrally formed convex plate, which is arranged around the outlet end tube body, and the end of the convex plate away from the outlet of the intake pipe 4 is an open structure for easy disassembly.

[0050] In this embodiment, the lower portion of the rear wall of the sewage collection tank 3 is concave inward to form a groove, the top surface of the groove is an inclined surface perpendicular to the middle section of the air intake pipe 4 and is provided with a through hole 31 for the middle section of the air intake pipe 4 to pass through. The air intake pipe 4 passes vertically through the top inclined surface of the groove, which can ensure the sealing between the sewage collection tank 3 and the air intake pipe 4 and prevent water overflow.

[0051] In a specific implementation, the air inlet pipe 4 passes through the through hole 31 on the top slope of the groove.
