Technical Field

The utility model relates to an intelligence squatting pan bath system, concretely relates to intelligence squatting pan bath system's automatically controlled three-way valve.

Background

An intelligent toilet bowl in the bathroom industry generally uses a pulse electromagnetic valve to control the opening and closing of a flushing waterway, when the intelligent toilet bowl is electrified, an electromagnetic coil generates electromagnetic force to lift a closing part from a valve seat, and the valve is opened; when the power is off, the electromagnetic force disappears, the spring presses the closing part on the valve seat, and the valve is closed. It has the following disadvantages: 1. the electromagnetic valve is usually only in two states of opening and closing, the valve core can only be positioned at two extreme positions and cannot be continuously adjusted, and the adjustment precision is limited to a certain extent; 2. meanwhile, the requirement on the cleanliness of water quality is high, so that the waterway cannot be opened or closed normally due to water pollution in the valve or wear and aging of a valve body diaphragm, the failure rate is frequent, a user cannot use the valve normally, and the life quality is seriously affected.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

Referring to fig. 1-7, the present embodiment includes a housing 1, the housing 1 includes an upper housing 11 and a lower housing 12, the upper housing 11 and the lower housing 12 are engaged with each other, a ball valve 2 is disposed between the upper housing 11 and the lower housing 12, and a valve shaft G of the ball valve 2 extends above the upper housing 12 and is connected to an electrically controlled actuator 3. Go up casing 11 and casing 12 inner chamber down and be three way pipe, three way pipe includes inhalant canal C, first exhalant canal A and second exhalant canal B. The ball body 21 of the ball valve 2 is of an irregular inner cavity structure and comprises a first ball body area D1, a second ball body area D2 and a valve body passage area E. When the ball valve 2 is closed, the first ball region D1 completely closes the water inlet passage, and the second ball region D2 completely closes the first water outlet passage. The electrically controlled actuator 3 can control the ball valve 2 to rotate in the housing 1.

The position corresponding to the first water outlet channel A is a lower flushing opening of the closestool, and the position corresponding to the second water outlet channel B is an upper flushing opening of the closestool.

The working process is as follows:

1. in the initial closed state, the first spherical area D1 completely closes the water inlet channel C, no water flows out of the first water outlet channel A and the second water outlet channel B, and no water backflow of the first water outlet channel A and the second water outlet channel B to the water inlet channel C occurs. At this time, no water flows out of the toilet flusher in the toilet.

2. An upper flushing washing opening state: the electric control actuator 3 drives the valve shaft G to rotate clockwise, the second ball area D2 and the first water outlet channel A are always in a closed state, at the moment, water flows out from the water inlet channel C through the valve body channel area E and enters the second water outlet channel B, and at the moment, C-E-B in the attached drawing is in a communicated state. At the moment, the upper flushing port of the closestool flushes water to flush the surface of the inner pot of the closestool, the dirt remained on the surface of the porcelain body flushes into the water storage pot, and the lower flushing port of the closestool does not flush water.

If the water supply is cut off suddenly, the electric control driver 3 springs the valve shaft G back to the initial closing state 1. The electric controller drives the 3 ball valve 2 to rotate by 90 degrees, the spring is pushed to store energy by rotation, the power is automatically cut off when the angle reaches 90 degrees, and the ball valve 2 is reset by the spring.

2-1. instantaneous simultaneous opening state of undershoot and overshoot: the electric control driver 3 continues to drive the valve shaft G to rotate clockwise, water flows out from the water inlet channel C through the valve body channel area E and enters the first water outlet channel B (corresponding to the upper flushing opening of the closestool), C-E-B in the attached drawing is in a communicated state, meanwhile, C-E-A is communicated, the lower flushing water quantity flowing out of the first water outlet channel A is gradually increased, and the upper flushing water quantity flowing out of the second water outlet channel B is gradually reduced. At the moment, water flows out of the flushing opening and the lower flushing opening of the closestool, and dirt is collected towards the direction of the pipeline gradually.

3. The lower flushing brush is in a fully opened state: the electric control driver 3 continues to drive the valve shaft G to rotate clockwise, when the valve shaft G rotates 90 degrees from the initial state, the water inlet channel C is communicated with the valve body channel area E and the first water outlet channel A, the first ball body area D1 and the second water outlet channel B are closed, water completely flows out of the first water outlet channel A, the water volume reaches the maximum, siphoning is generated at the lower water jet of the closestool, and sewage is discharged from the pipeline step by step. At the moment, all water flows out of the lower toilet flushing port, and no water flows out of the upper toilet flushing port.

4, the simultaneous opening state of the down-stroke washing and the up-stroke water replenishing washing: the electric control driver 3 drives the valve shaft G to rotate anticlockwise, the second ball body area D2 gradually closes the first water outlet channel A, water flows out from the water inlet channel C through the valve body channel area E and enters the second water outlet channel B, C-E-B is in a communicated state in the drawing, meanwhile, C-E-A is communicated, along with the continuous rotation of the valve shaft G, the water yield of the first water outlet channel A is gradually reduced, the water yield of the second water outlet channel B is gradually increased, dirt continues to be discharged from a pipeline, the second flushing of the toilet seat surface is started, and at the moment, water flows out of a flushing port and a lower flushing port of the toilet seat.

4-1, an upward water replenishing and fully opening state: the electric control driver 3 drives the valve shaft G to rotate anticlockwise continuously to reach a second ball area D2 and a first water outlet channel A in a completely closed state, at the moment, water flows out from the water inlet channel C through a valve body channel area E and enters a second water outlet channel B, C-E-B is in a communicated state in the drawing, at the moment, siphoning of the closestool is finished, the water seal height is insufficient due to siphoning, water flowing out from the second water outlet channel B is completely supplemented with water to restore the water seal height, at the moment, a flushing port on the closestool is provided with water flowing out, and no water rushes out from a lower flushing port.

5. And (4) recovering the initial off state: the electric control actuator 3 drives the valve shaft G to rotate continuously anticlockwise, and when the valve shaft G rotates anticlockwise for 90 degrees, the first spherical area D1 completely closes the water inlet channel C; neither the first water outlet channel A nor the second water outlet channel B has water flowing out, and the situation that the water in the first water outlet channel A and the water in the second water outlet channel B flows back to the water outlet channel C can not happen, and at the moment, the water outlet channels are restored to the initial closing state.

Various modifications and variations of the present invention may be made by those skilled in the art, and they are still within the scope of the present invention, provided they are within the scope of the claims and their equivalents.

What is not described in detail in the specification is prior art that is well known to those skilled in the art.
