Description

Technical Field

[0001] This utility model relates to the field of cleaning machine technology, specifically to a water-blocking structure for a cleaning machine. Background Technology

[0002] A cleaning machine is a multi-functional cleaning device widely used in homes, businesses, and industries. It uses a vacuum motor to create a vacuum in the wastewater tank, and a squeegee pulls the wastewater through a suction pipe back into the tank, achieving simultaneous cleaning and drying.

[0003] The prior art (Chinese patent publication number: CN216724468U, publication date: 2022-06-14) discloses a wastewater tank for a floor scrubber and a floor scrubber. The wastewater tank includes: a housing with an inner cavity, an air inlet and an air outlet respectively communicating with the inner cavity, the air outlet being connected to the suction fan of the floor scrubber; and a baffle assembly, including a baffle movably disposed in the housing for opening or closing the air inlet, and an elastic member connecting the housing and the baffle. The baffle can open the air inlet under the suction force of the suction fan, and the baffle can reset under the force of the elastic member to close the air inlet. The provided wastewater tank for a floor scrubber automatically opens the air inlet when the floor scrubber is working and automatically closes the air inlet when the floor scrubber stops working, ensuring that wastewater or solid particles collected in the tank will not overflow from the air inlet when the floor scrubber is picked up or moved by the user. This provides a good user experience and is simple in structure and low in cost.

[0004] While existing floor scrubbers automatically close the air inlet when they stop working to reduce wastewater overflow, they cannot buffer or block the water during use. After the water enters the wastewater tank through the flow channel, the wastewater will still seep into the motor through the air channel due to the suction of the external motor, thus damaging the motor. This has certain limitations.

[0005] Therefore, we proposed a water-blocking structure for the cleaning machine to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this utility model is to provide a water-blocking structure for a cleaning machine, in order to solve the problem mentioned in the background art that the cleaning machine cannot buffer or block the water during use. After the water enters the sewage tank through the flow channel, the sewage will still seep into the motor through the air duct due to the suction of the external motor, thereby damaging the motor. This presents certain limitations.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a water-blocking structure for a cleaning machine, comprising a soft rubber water-blocking plate and a fixed water-blocking plate disposed inside the housing. The fixed water-blocking plate is fixedly connected to the inner side of the housing, and a guide plate is fixedly connected inside the housing. A return flow baffle is fixedly connected to the lower end of the guide plate. The soft rubber water-blocking plate is disposed on the return flow baffle. Through the cooperation between the soft rubber water-blocking plate and the fixed water-blocking plate, the impact force of water drawn into the housing can be buffered, thereby further blocking water vapor.

[0008] Furthermore, the inner side of the shell is provided with a water inlet channel for water flow, and the outer end of the water inlet channel extends to the outer side of the shell to form a channel opening. The shell is also provided with a sewage tank for holding sewage.

[0009] Furthermore, the inner port of the flow channel is located on the upper surface of the guide plate, and the guide plate is arranged in an arc shape when viewed from the side, and the end of the guide plate is located obliquely above the fixed baffle plate.

[0010] Furthermore, the fixed baffle plate has a horizontally arranged "S" shape in side view, which can reduce the impact force of water entering the shell.

[0011] Furthermore, a suction duct for gas flow is formed between the return baffle and the housing, and the upper end of the soft rubber baffle is in contact with the inner wall of the suction duct.

[0012] Furthermore, the soft rubber baffle is made of elastic material and has gaps for gas to pass through. The soft rubber baffle can reduce the amount of water vapor drawn into the external motor through the air intake duct.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The shell is equipped with a fixed baffle plate located on the lower side of the guide plate. When water is sucked into the water inlet by the suction of the external motor, the guide plate will initially guide the water so that the water can flow accurately to the top of the fixed baffle plate.

[0015] After being guided by the arc-shaped baffle, the water falls onto the fixed baffle. The fixed baffle, which is set in an "S" shape, can catch the water in one go, thereby reducing the impact force on the water when it is sucked into the sewage tank. This also reduces the phenomenon of water splashing up and being sucked in by the wind force of the motor.

[0016] 2. The upper part of the soft rubber baffle is in contact with the inner side of the water inlet channel. When the external motor performs suction operation, its air force will be drawn into the air duct through the gap reserved on the soft rubber baffle. At the same time, the soft rubber baffle will also block water vapor, reducing the occurrence of water vapor being drawn into the external motor.

[0017] 3. The combination of soft rubber baffles and fixed baffles provides double protection against water entering the sewage tank, further reducing the entry of water vapor and preventing it from being sucked into the air intake duct or even flowing to the external motor.

[0024] Example 1: As Figure 1 and Figure 2The technical solution shown herein provides the following technical solution: a water-blocking structure for a cleaning machine, disclosing a soft rubber water-blocking plate 1 and a fixed water-blocking plate 2. The soft rubber water-blocking plate 1 and the fixed water-blocking plate 2 prevent water vapor from being drawn into the air intake duct 6, or even flowing to the external motor. The soft rubber water-blocking plate 1 and the fixed water-blocking plate 2 are installed inside the housing 3. The fixed water-blocking plate 2 is fixedly connected to the inner side of the housing 3, and a guide plate 8 is fixedly connected inside the housing 3. A return flow baffle 7 is fixedly connected to the lower end of the guide plate 8. The soft rubber water-blocking plate 1 is installed on the return flow baffle 7. The soft rubber baffle 1 and the fixed baffle 2 work together to buffer the impact of water entering the housing 3, thereby further blocking water vapor. The inner side of the housing 3 is provided with a water inlet channel 9 for water flow, and the outer end of the water inlet channel 9 extends to the outer side of the housing 3 to form a flow channel opening 5. The housing 3 is provided with a sewage tank 4 for holding sewage. The inner port of the flow channel opening 5 is located on the upper surface of the guide plate 8, and the guide plate 8 is arranged in an arc shape when viewed from the side. The end of the guide plate 8 is located diagonally above the fixed baffle 2.

[0025] The housing 3 has a fixed baffle 2 located on the lower side of the guide plate 8. When water is sucked into the inlet channel 9 from the flow port 5 by the suction of the external motor, the guide plate 8 will initially guide the water, so that the water can flow accurately to the top of the fixed baffle 2. The setting of the soft rubber baffle 1 and the fixed baffle 2 can provide double protection and block the water entering the sewage tank 4, further reducing the entry of water vapor and preventing water vapor from being sucked into the air intake duct 6 or even flowing to the external motor.

[0026] Example 2: Figure 2 and Figure 3 The present invention provides the following technical solution: a water-blocking structure for a cleaning machine, which discloses a fixed water-blocking plate 2. The fixed water-blocking plate 2 can reduce the impact force on the water when it is sucked into the sewage tank 4. The fixed water-blocking plate 2 has a horizontally arranged "S"-shaped structure in side view. The fixed water-blocking plate 2 can reduce the impact force on the water entering the shell 3. A suction duct 6 for gas flow is formed between the return baffle 7 and the shell 3. The upper end of the soft rubber water-blocking plate 1 is attached to the inner wall of the suction duct 6.

[0027] After the water is guided by the arc-shaped guide plate 8, it will fall onto the fixed baffle plate 2. The fixed baffle plate 2, which is set in an "S" shape, can catch the water in one go, thereby reducing the impact force on the water when it is sucked into the sewage tank 4, reducing the direct flow of water into the sewage tank 4, and preventing the phenomenon of water splashing up and being sucked in by the wind force of the motor.

[0028] Example 3: Figure 2 and Figure 4The present invention provides the following technical solution: a water-blocking structure for a cleaning machine, which discloses a soft rubber water-blocking plate 1. The soft rubber water-blocking plate 1 can block water vapor. The soft rubber water-blocking plate 1 is made of elastic material and has gaps on it for gas to pass through. The soft rubber water-blocking plate 1 can reduce the amount of water vapor drawn into the external motor through the air intake duct 6.

[0029] The upper part of the soft rubber baffle 1 is in contact with the inner side of the water inlet channel 9. When the external motor performs suction operation, its air force will enter the air duct 6 through the gap reserved on the soft rubber baffle 1. At the same time, the soft rubber baffle 1 will also block water vapor, reducing the phenomenon of water vapor being sucked into the external motor.
