Description
Technical Field
The utility model relates to a self-closing valve field specifically relates to a time delay case and tap with time delay hole.
Background
At present, the water taps with the automatic closing function in the market mainly include the following two types:
the first is for being provided with infrared sensor's intelligent tap, the start and stop of this kind of tap is controlled through the infrared sensor who sets up on tap, if when people's hand is close infrared sensor, infrared sensor can send first detected signal to the last control chip of tap, make control tap go out water, when people's hand is kept away from infrared sensor, infrared sensor can send the second detected signal to the last control chip of tap, make control tap close, but the shortcoming of this type of product is that infrared sensor needs the standby work that lasts, power consumption is big, high in manufacturing cost, easy damage under the moist environment of electron product simultaneously.
The second type is a water tap with a time-delay valve core, the opening and closing of the water tap is controlled by a mechanical structure in the time-delay valve core, when the valve core component of the time-delay valve core is pressed, the valve core component slides and moves relative to the valve body, a passage is formed between the valve core component and the valve body, water flows out of the water tap through the passage, and meanwhile, a reset spring for resetting the valve core component is compressed for energy storage. When the pressing of the valve core assembly is released, the valve core assembly is reset under the action of the elastic force of the reset spring, so that the passage is closed. And because the valve core assembly can be influenced by the pressure difference in the valve body, the resetting speed of the valve core assembly is slower, and a delayed closing effect is generated, so that after a user releases the pressing on the valve core assembly, the faucet can still keep a water outlet state within a preset time and is automatically closed when the preset time is exceeded. However, the existing time delay valve core has more defects, for example, the valve core has a complex structure and many parts; the delay hole of the inner container cavity is easy to be blocked, and the delay needle is easy to be broken off in the process of repeated movement of the piston rod, and the like. The control stability of the time delay valve core is poor due to the defects, even the time delay valve core cannot accurately control the time delay closing time, and when the time delay closing time is too long, water resources are wasted; when the time delay closure time is short, can't be according to satisfying the user's demand, appear even long-time use back, can appear tap not going out water or case subassembly can't realize the time delay after being pressed and close the scheduling problem when pressing the valve core subassembly.
