For large areas, manual cleaning is inefficient and consumes a lot of labor costs. Existing automated cleaning equipment has shortcomings such as single function and harmful gas emissions during work, which cannot meet people's needs. As a new type of intelligent cleaning equipment, the floor washing machine is suitable for hard floors. It can clean and dry the sewage at the same time, and take the sewage away from the scene. It has the advantages of environmental protection, high cleaning efficiency, convenient use, and labor saving. It is loved by people. ,with broadly application foreground.

At present, most scrubbers on the market often face water distribution problems when using double brush discs to scrub the floor. When using a scrubber with double brushes, a water pipe needs to be used to divert water from the clean water tank, and then distribute it evenly to the left and right brushes. However, during the working process of the washing machine, the brush plate on one side may work normally, while the brush plate on the other side cannot supply water, which brings great trouble to the cleaning work.

Contents of the invention

The inventor found through research that, due to the low water level of the clean water tank of the washing machine, the pressure difference of the outflowing water flow is very small, which cannot drive the water flow forward, and the process of the water flow from the clean water tank into the brush plate is basically realized by natural flow. Since the shunt pipe connecting the water outlet of the water tank and the brush plate is a hose that cannot be precisely controlled, and the shunt pipe will fluctuate with the brush plate mounting plate during the working process of the scrubber, it is difficult to keep the shunt pipes on the left and right sides completely consistent. height and angle. Therefore, the air in the fresh water tank can easily enter the shunt pipe and stay on the top of its inner wall, and most of the air flows to the shunt pipe on the higher side, so there is often a big difference in the amount of air trapped in the shunt pipes on the left and right sides. The pressure generated by the air at the high point on the inner wall of the shunt pipe on the side with a large amount of trapped air is greater than the pressure difference of the water flow, so it will affect the flow rate of the low-pressure water flow, and even block the pipeline of the shunt pipe, causing the water flow on this side to stop. There is no water supply to one brush plate of the scrubber, so the brush plate on one side is working normally, but the other brush plate has no water supply.

Therefore, the present invention provides a device capable of maintaining the balance of water supply to the brush tray in order to avoid the above-mentioned deficiencies in the prior art.

The purpose of the invention is achieved through the following technical solutions:

The water outlet pipe 12 is connected to the washing machine through the shunt pipe 2. The brush plate of the ground car. The exhaust pipe 13 is located at the top of the intersection of the water inlet pipe 11 and the water outlet pipe 12, and the air in the water flow is discharged through the exhaust pipe. The washing machine is equipped with a corresponding number of water outlet pipes 12 according to the number of brush plates. The washing machine has a double brush plate structure. The left and right brush plates supply water. The shunt pipe 2 is sleeved at the water outlet of the water outlet pipe 12, the left water outlet 121 is correspondingly connected to the left shunt pipe 21, and the right water outlet 122 is correspondingly connected to the right shunt pipe 22, the size of the two water outlets is equal, and the diameter of the two shunt pipes Also, the water flow is equally distributed to the left and right brush plates.

Preferably, the liquid separator 1 is a positive three-way pipe structure with an exhaust pipe formed integrally, the water inlet pipe 11 is the main pipe of the three-way pipe, and the outlet pipe 12 is two horizontal branch pipes of the three-way pipe structure. The water inlet pipe 11 and the water outlet pipe 12 are perpendicular to each other. The water inlet pipe 11 and the water outlet pipe 12 that are perpendicular to each other and arranged on the horizontal plane can ensure that the water flow of each water outlet that is diverted from the water inlet pipe 11 to the water outlet pipe 12 is kept in balance, and is evenly supplied to each brush plate. The exhaust pipe 13 is a cylindrical pipeline with an upward opening, and is vertically arranged on the top of the intersection of the water inlet pipe 11 and the water outlet pipe 12 .

When the floor scrubber is working, the water in the clean water tank flows into the liquid distributor 1 through the water inlet pipe 11, and the water flow is diverted at the intersection of the water inlet pipe 11 and the water outlet pipe 12, and flows to different outlets of the water outlet pipe 12, forming a number corresponding to the number of shunt pipes 2. water branch. At the same time, as shown in FIG. 2 , the air entering the liquid separator 1 with the water flow can be discharged to the outside of the liquid separator 1 through the exhaust pipe 13 instead of staying inside the water outlet pipe 11 and the shunt pipe 2 . When the outlet pipes 12 on the left and right sides of the washing machine cannot maintain the same height and angle, such as the outlet pipe 12 shown in Fig. The air in the shunt pipe 21 flows back from the left water outlet 121 back to the outlet pipe 12, because there is an exhaust pipe 13 at the top of the pipe where the outlet pipe 12 and the inlet pipe 11 meet, and the air can be discharged from the outlet pipe 13 by flowing back to the outlet pipe 12 The device 1 ensures the uniformity and stability of the water flow, thereby maintaining the water supply balance of the brush plate.
