Description

Technical Field

[0001] The utility model belongs to the technical field of faucets for automatically controlling waterway switching (waterway switching by key operation on an operation panel), and particularly relates to a two-inlet and four-outlet electric valve for an intelligent toilet. Background Art

[0002] There are two main methods for controlling the water flow of existing faucets. One is to manually control the water flow through the valve handle, and the other is to control the water flow by sending and receiving signals through the sensing component to control the electric control switch, such as the solenoid valve switch. Since the induction faucet can turn the faucet on and off without touching the faucet body, it is not only convenient to use, but also helps to keep the faucet surface clean. There are two modes of induction faucets. One is the long water flow mode, which turns on the faucet by sensing once and turns off the faucet by sensing again. The other is the induction water flow mode, which sets the conditions for turning on the faucet. It turns on when the conditions are met and turns off when the conditions are not met. For example, the faucet is turned on when an object is sensed at the predetermined position, and the faucet is turned off when no object is sensed at the predetermined position; or, the faucet is turned on when the faucet handle or the water outlet is detected to have left the predetermined position, and the faucet is turned off when the faucet handle or the water outlet is detected to be at the predetermined position.

[0003] For example, the Chinese invention patent application "A Kind of Induction Faucet Valve Core" with application number CN2202110211437.X (publication number CN112833221A) discloses such a valve core structure. However, this valve core still has the defect that it cannot sense water after the electromagnetic valve switch is damaged. The function of the electromagnetic valve switch is to open and close the water path, that is, to control the water flow through induction. If the water path is to be switched, the valve stem must be manually operated to drive the moving valve plate to rotate. Therefore, this valve core is only suitable for induction faucets.

[0004] In response to this situation, a ceramic conversion valve core was later developed that directly manipulates the buttons set on the operation panel to switch the water path. For details, please refer to the Chinese utility model patent "One-inlet and three-outlet electric ceramic conversion valve core" with application number CN 202121888849.9 (publication number CN216158358U), which includes a valve housing, a fixed valve plate, a moving valve plate, a rotor and a motor, etc. The valve housing is provided with a first water outlet channel, a second water outlet channel, a third water outlet channel and a water inlet channel, the fixed valve plate is fixed in the valve housing, the fixed valve plate is provided with a first water outlet hole, a second water outlet hole and a third water outlet hole, the moving valve plate is arranged in the valve housing, and a switching hole is opened on the moving valve plate. The rotation of the valve plate can make the switching hole communicate with the first water outlet hole, the second water outlet hole or the third water outlet hole, and the water inlet channel is connected with the inner cavity of the valve shell above the moving valve plate. The rotor is arranged in the valve shell, and the lower end of the rotor is connected to the moving valve plate. A first sealing member is provided between the outer periphery of the rotor and the inner cavity wall of the valve shell. The motor is fixed on the top of the valve shell, and the output shaft of the motor extends into the valve shell and is connected to the rotor. Since the valve core adopts a motor to directly drive the moving valve plate to rotate, it can realize automatic control switching of multiple water channels without manual drive.

[0005] However, there is a problem with this type of valve core. Since this type of valve core is generally used in smart toilets, with the continuous development of smart toilets, this type of valve core with only one inlet and three outlets can no longer meet the requirements, especially in the actual application of smart toilets. In order to make splash prevention or flushing cleaner, it is often necessary to form foam in the water flow, and to form foam, gas needs to enter the water flow to cooperate in this realization.

[0006] Therefore, how to provide a ceramic valve core for smart toilets that has a reasonable and compact structural design, has both a water inlet channel and an air inlet channel to better form foam, and has four water outlet channels to meet more needs is an urgent problem that technicians in this field need to solve.
