Example 1

Referring to fig. 1-7, the present invention provides the following technical solutions: a multifunctional control pneumatic control drain valve comprises a button assembly 1, an air pump 2, a drain valve assembly 3, an air escape valve assembly 4, a first pipeline 5 and a second pipeline 6; the air pump 2 is arranged above the drain valve component 3 through an air pump mounting seat, the air release valve component 4 is fixed on one side of the drain valve component 3 through a fastening buckle, a drain valve inner core tube 31 is arranged inside the drain valve component 3, and a half-discharge inner sleeve 32 and a full-discharge inner sleeve 33 which are connected with the drain valve inner core tube 31 are also arranged on the drain valve component 3; the air pump 2 is respectively connected with the button assembly 1, the drain valve assembly 3 and the air escape valve assembly 4 through pipelines; the drain valve assembly 3 and the air release valve assembly 4 are connected with the button assembly 1 through pipelines.

Specifically, the air release valve assembly 4 consists of an air release valve buoy 41, a first pipeline 5 and a second pipeline 6, the first pipeline 5 consists of a first air pipe assembly 51, a rubber piston 52, a spring 53 and a second air pipe assembly 54, and the second pipeline 6 consists of a third air pipe assembly 61, a rubber piston 52, a spring 53 and a second air pipe assembly 54; the air release valve buoy 41 is arranged above the air release valve assembly 4, the first air pipe assembly 51 and the third air pipe assembly 61 are respectively assembled and connected with the second air pipe assembly 54, and a rubber piston 52 and a spring 53 are arranged between the first air pipe assembly 51, the third air pipe assembly 61 and the second air pipe assembly 54; the first air pipe assembly 51 and the third air pipe assembly 61 are connected with the air release valve buoy 41 through the second air pipe assembly 54 through a pipeline on the air release valve assembly 4.

Specifically, the air pump 2 is connected with a first pipeline 5 and a drain valve component 3 through a three-way pipe by an air pipe; the button component 1 is connected with the second pipeline 6 and the drain valve component 3 through a three-way pipe by an air pipe.

When in use:

1. when the water level of the water tank rises, the float assembly (c in the figure 3) in the main body of the air release valve assembly 4 rises along with the water level, and the air release port is tightly pressed (d in the figure 3) and keeps a closed state.

2. Thus, when the pneumatic control button assembly 1 is manually pressed, the air pressure in the button air bag passes through the component tee joint of the second pipeline 6, and the pressure of the air flow is divided into the full-discharge inner sleeve assembly of the drain valve and the air release valve float 41 of the air release valve assembly 4 of the second pipeline 6. At this time, the drain valve inner core tube 31 and the full drain inner sleeve 33 of the drain valve assembly 3 will rise along with the increase of the air pressure to open the drain valve inner core tube 31, and start the draining operation.

3. The rubber piston 52 in the one-way check valve of the second pipeline 6 pushes the one-way valve internal spring 53 to open the closed rubber piston 52 to exhaust (as shown in e in fig. 6) along with the pressure of the air flow. At the moment, the float assembly of the air release valve descends along with the float assembly of the air release valve, and air begins to release after a gap is formed in an air release hole of the body of the air release valve assembly 4. At this time, the inner core tube assembly and the inner sleeve 33 assembly of the drain valve close the drain opening along with the descending, and the draining action is stopped.

4. Meanwhile, the rubber piston 52 is pushed to close by the force of the spring 53 due to the decrease of the air pressure in the one-way check valve of the first pipeline 5 in the opposite direction, and at this time, the exhaust port of the one-way check valve of the first pipeline 5 is kept in a sealed state (as shown in f in fig. 7). The air pressure in the air pipe is not insufficient due to the air leakage of the air control pipeline at the other side, and the control action stability of the hand-waving induction air control loop at the other side of the drain valve is ensured.

Example 2

Please refer to fig. 8-11, which is different from the technical features of embodiment 1: a hand waving induction probe component 7 is arranged on the button component 1; the hand swing induction probe assembly 7 is connected with a controller arranged on the air pump 2 through a signal wire.

When in use:

1. when the water level rises when the water tank is filled with water, the air release valve assembly 4 rises along with the floating cylinder assembly (c in the figure 3) in the main body, the air release port is pressed (d in the figure 3) and keeps a closed state

2. Thus, when the button is sensed by the sensing probe assembly 7 during hand swing, the air pressure pumped by the air pump 2 flows through the member tee joint of the first pipeline 5 to divide the pressure of the air flow to the semi-row inner sleeve assembly and the air escape valve float 41 of the air escape valve assembly 4 of the first pipeline 5; the drain valve inner core tube 31 and the half-drain inner sleeve component of the drain valve component 3 can open the drain valve core along with the rise of air pressure and drain water normally.

3. Meanwhile, the rubber piston member in the one-way check valve of the first pipeline 5 pushes the spring in the one-way check valve to open the closed rubber piston to exhaust (as shown in e in fig. 10) along with the pressure of the airflow, at this time, the air release valve float 41 of the air release valve assembly 4 descends along with the spring, and the air release hole of the body of the air release valve assembly 4 generates a gap and then begins to release air. At this time, the drain valve inner core tube 31 and the half drain inner sleeve 32 of the drain valve assembly 3 close the drain opening along with the descending, and the drain operation is stopped.

4. And the rubber piston 52 is pushed by the one-way check valve inner spring 53 of the reverse second pipeline 6, and the one-way check valve exhaust port of the second pipeline 6 is kept in a sealed state (as shown in f in the above figure 11). The air pressure in the air pipe cannot be insufficient due to the air leakage of the air control pipeline at the other side, and the control action of the hand-press air control loop at the other side of the drain valve component 3 can be stably executed.

The hand-waving induction pneumatic control type drain valve can be used for sensing full drainage within 3 seconds of hand-waving induction and half drainage after 3 seconds of hand-waving induction, and a multifunctional drainage button for full drainage is manually pressed.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
