Description

Technical Field

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

[0002] A floor scrubber is a cleaning appliance that integrates vacuuming, mopping, and scrubbing. It is suitable for handling mixed dry and wet waste, and is especially suitable for families with pets, children, or those who frequently need deep cleaning, as well as commercial places such as shopping malls and restaurants. It can simultaneously perform vacuuming, mopping, and self-cleaning roller brush, saving time and effort.

[0003] The prior art (Chinese patent publication number: CN217510391U, publication date: 2022-09-30) discloses a roller brush box for a floor scrubber, comprising: a box body, the box body having a mounting cavity for mounting the roller brush, and a suction port communicating with the mounting cavity; and a scraper strip disposed in the box body for contacting the roller brush, the scraper strip being distributed along the length of the roller brush, the scraper strip being arranged in a V-shape or U-shape, and the middle position of the scraper strip being opposite to the suction port. The provided roller brush box for the floor scrubber, through the V-shaped or U-shaped scraper strip, allows debris or wastewater on the roller brush to be completely gathered along the V-shaped or U-shaped scraper strip to the suction port, enabling the debris or wastewater to be completely sucked into the dust box from the suction port, thereby effectively improving the cleaning efficiency of the floor scrubber.

[0004] While existing technology allows garbage or sewage to be completely sucked into the dust box through the suction port, the water level inside the sewage tank changes when the user holds the cleaning machine after it has been filled with sewage. As a result, the water can flow back through the air intake channel to the suction motor, causing damage to the device.

[0005] Therefore, we proposed a structure to prevent water backflow in the cleaning machine in order to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this utility model is to provide a structure to prevent water backflow in a cleaning machine, so as to solve the problem mentioned in the background art that when the sewage tank of the cleaning machine is filled with sewage, the water level inside the sewage tank changes when the user holds the cleaning machine body for use. As a result, the water will backflow through the air inlet channel to the suction motor, thereby damaging the device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a backflow prevention structure for a cleaning machine, including an anti-backflow component installed inside the cleaning machine body. The anti-backflow component includes an air inlet channel providing a channel for wind power delivery and a sewage tank for holding sewage. The anti-backflow mechanism can prevent water backflow through the cooperation of the sewage tank and the air inlet channel.

[0008] Furthermore, the cleaning machine body has an internal rear side equipped with a suction motor that can provide adsorption force to water, and the output end of the suction motor is connected to the sewage tank through an air inlet channel.

[0009] Furthermore, the air inlet channel is inclined toward the upper end of the cleaning machine body, and the air inlet of the air inlet channel is close to the top of the sewage tank, and the sewage tank is located on the lower side of the cleaning machine body.

[0010] Furthermore, a soft rubber waterproof board that can buffer the water is installed below the upper water inlet of the sewage tank.

[0011] Furthermore, the lower side of the wastewater tank extends towards the handle of the cleaning machine body, and the lower side of the wastewater tank has a trapezoidal structure.

[0012] Furthermore, the width of the wastewater tank is greater than the maximum width of the cleaning machine body.

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

[0014] 1. The wastewater tank is moved back towards the handle of the cleaning machine body to increase its water storage capacity. When the user holds the handle of the cleaning machine body to use the device, both the cleaning machine body and the wastewater tank are in a vertical position. The wastewater tank can hold more water through its extension structure near the handle, thereby reducing the height of the water level and further reducing the occurrence of water backflow.

[0015] 2. The cleaning machine body is equipped with a soft rubber waterproof plate inside, which can buffer the impact of the water being sucked in. The impact of the water is reduced by the soft rubber waterproof plate, so that when the water comes into contact with the sewage, the splashing water is smaller and the overall fluctuation of the sewage is also smaller. This further prevents the water from shaking too much and causing backflow.

[0016] 3. The air inlet of the air inlet channel for gas delivery is located close to the top of the sewage tank. When the suction motor is running, its suction power can be used to perform suction operations through the air inlet channel. At the same time, the distance between the air inlet channel and the water surface inside the sewage tank is relatively far, thereby further preventing water from flowing back and causing water to enter and damage the suction motor.
