At present, a water pump is communicated with a water outlet of a self-suction barrel through a water pipe, and a water inlet of the self-suction barrel is communicated with a water source, such as a water pool and the like. The water pump is typically manually filled into the tank prior to initial operation. The liquid inlet of the self-suction barrel is higher than the water level in the barrel, so that water in the barrel cannot flow back to enter the water tank, and the self-suction barrel can store certain amount of water. And because the height of the liquid outlet of the self-suction barrel is lower than the height of the water surface in the barrel, the water pump can be ensured to be continuously in a water filling state, and the water pump can be ensured to be started at any time. When the water pump is in operation, water in the barrel is pumped away by the water pump, negative pressure occurs in the barrel, and water in the water pool is supplemented into the self-suction barrel under the action of atmospheric pressure, so that certain water can be stored in the barrel. However, most of the self-priming buckets in the market are easily damaged by water pressure at the top of the self-priming bucket when the water pump stops working, and meanwhile, the water level in the self-priming bucket is gradually lowered in the working process of most of the self-priming buckets, so that the pumping capacity of the water pump is reduced, and even the water pump can be damaged in a serious case.

Wherein, the top of the barrel body 10 is provided with a check valve 30, and the check valve 30 is used for discharging the liquid in the barrel body 10 to the outside. The lateral part of the barrel body 10 is provided with a liquid inlet pipe 40 and a liquid outlet pipe 50, the liquid outlet pipe 50 extends into the barrel body 10 to form an extension section 51, the liquid inlet pipe 40 is used for conveying liquid into the barrel body 10, and the liquid outlet pipe 50 is used for discharging the solution in the barrel body 10 to the outside. The pumping tube 20 extends along the axial direction of the tub 10, one end of the pumping tube is communicated with the extension 51, the opposite end is disposed near the top of the tub 10, and the pumping tube 20 is used for pumping the gas in the tub 10.

In practice, the check valve 30 is connected to a liquid collection device such as a liquid collection tank, and the liquid inlet pipe 40 is connected to a liquid source and the liquid outlet pipe 50 is connected to a pump. During operation of the pump, the pump pumps the solution in the barrel body 10 through the liquid outlet pipe 50, and simultaneously the gas in the barrel body 10 is pumped through the pumping pipe 20, so that the occupied space of the gas in the barrel body 10 is reduced, more liquid can be input into the barrel body 10 through the liquid inlet pipe 40, the liquid level of the solution in the barrel body 10 is kept relatively stable, and the pumping amount of the pump is reduced due to the fact that the liquid level is reduced. When the pump stops working, the check valve 30 can buffer the instantaneous strong liquid pressure, that is, the check valve 30 can discharge the solution in the barrel 10 to the outside to buffer the liquid pressure, thereby protecting the top of the self-priming barrel from being damaged.

As shown in fig. 1, the top of the barrel 10 is further provided with a liquid inlet valve 60 and a liquid outlet valve 70, wherein the liquid inlet valve 60 is used for controlling whether to input liquid into the barrel 10, and the liquid outlet valve 70 is used for controlling whether to discharge liquid and/or gas from the barrel 10 to the outside. In practice, before the self-priming bucket is used, in order to exhaust the gas therein, liquid is injected into the bucket body 10 through the liquid inlet valve 60, so as to exhaust the gas to the outside through the liquid outlet valve 70. After the gas is discharged, inlet valve 60 and outlet valve 70 may be closed.

In this embodiment, the check valve 30 is connected to the barrel 10 through the liquid outlet valve 70, that is, when the pressure of the liquid is buffered, the liquid firstly enters the liquid outlet valve 70, then enters the check valve 30, and finally is discharged to the outside through the check valve 30. Of course, in other embodiments, the check valve 30, the liquid outlet valve 70 and the liquid inlet valve 60 may be separately disposed on the top of the barrel 10, and may be disposed according to actual requirements.

As shown in FIG. 1, in order to fix the suction pipe 20, the suction pipe 20 is fixedly connected to the inner wall of the tub 10 by a pipe clamp 80. Of course, in other embodiments, the fixing of the exhaust tube 20 may be achieved by other means, such as welding, etc.

As shown in fig. 1, the tub 10 includes a top cover 10a, a bottom cover 10b, and a tub wall 10c connecting the top cover 10a and the bottom cover 10b, wherein the top cover 10a, the bottom cover 10b and the tub wall 10c are connected by welding, and the top cover 10a and the bottom cover 10b are formed by a CNC machining process. Furthermore, the top cover 10a is provided with the check valve, the liquid inlet valve and the liquid outlet valve, and the barrel wall 10c is provided with the liquid inlet pipe and the liquid outlet pipe. In this embodiment, the barrel body 10 is integrally cylindrical, but in other embodiments, the barrel body 10 may be configured in a square shape according to actual requirements.

As shown in fig. 1, the self-priming bucket further comprises a first connecting flange 90 and a second connecting flange 100, wherein the first connecting flange 90 is connected with the liquid inlet pipe 40, and the second connecting flange 100 is connected with the liquid outlet pipe 50. Through setting up flange, be convenient for advance, the connection and the dismantlement of drain pipe improve assembly efficiency.

The working principle of the self-priming bucket is as follows:

initially, the liquid inlet valve 60 and the liquid outlet valve 70 are opened, liquid is filled into the barrel body 10, and in the process of continuously filling liquid into the barrel body 10, gas in the barrel body 10 is discharged to the outside through the liquid outlet valve 70 and the check valve 30 in sequence. After the gas in the barrel 10 is discharged, the liquid inlet valve 60 is closed, and the liquid outlet valve 70 is still opened. When the pump works, the pump pumps the solution in the barrel body 10 through the liquid outlet pipe 50, and simultaneously the gas near the top in the barrel body 10 is pumped through the pumping pipe 20, so that the liquid level of the solution in the barrel body 10 is stable at a high position. When the pump stops working, the check valve 30 can buffer the instantaneous strong liquid pressure, that is, the check valve 30 can discharge the solution in the barrel 10 to the outside to buffer the liquid pressure, thereby protecting the top of the self-priming barrel from being damaged.

From inhaling bucket, through set up check valve 30 at staving 10 tops to avoid the pump stop work time fluid pressure to the impact at staving 10 tops, avoid the damage at staving 10 tops, the life of bucket is inhaled from the extension son. Meanwhile, the pumping pipe 20 is arranged in the barrel body 10, and the pumping pipe 20 is communicated with the air outlet pipe, so that the pump can pump out the gas in the barrel body 10 during pumping, the occupied space of the gas in the barrel body 10 is reduced, the liquid level of the solution in the barrel body 10 is kept relatively stable, and the problem of liquid level reduction during long-term operation of the self-priming barrel is solved.
