Detailed Description

Firstly, the design of the invention is designed originally, in the daily water use process of people, the condition that a water tap is forgotten to be closed often occurs, which causes waste of water resources, in order to solve the problem, a plurality of water taps with a time delay function appear on the market at present, the purpose of saving water is achieved by automatically closing after a period of time, but the time delay water taps all have fixed time delay time, the time is set by manufacturers and preset in products, and for the condition that different time delays are needed, corresponding products do not exist in the market at present.

The most core function of the invention is to realize the artificial control of the delay time of the water faucet, thereby meeting the requirements of people on the water delay time under different conditions.

The invention has the basic principle that the valve core 2 of the water tap is driven to move up and down by a common delayer or a timing switch 3 on the market, and the purpose of blocking or communicating the water inlet pipe and the water outlet pipe of the water tap is achieved by the up-and-down movement of the valve core 2. In order that the detailed structure of the present invention will be apparent to those skilled in the art, the following detailed description will be made with reference to the accompanying drawings 1-2:

firstly, explaining the overall structure of the water faucet, wherein a cavity is reserved in the water faucet, a valve core 2 and a component for controlling the action of the valve core 2 are placed in the cavity, and the control component is specifically that a timing switch 3 is arranged at the top of the valve core 2, the timing switch 3 is used for setting time and rotates when the preset time is reached, and then the valve core 2 is pressed downwards to fall; the bottom of the valve core 2 is provided with a spring 4 which keeps the valve core 2 to have upward movement tendency, the spring 4 is always in a compressed state, and when the timing switch 3 does not press the valve core 2 any more, the spring 4 can push the valve core 2 to move upwards; the specific structure of the valve core 2 of the water tap is that the valve core 2 is of a plunger type structure as a whole, the structure of the valve core 2 can be divided into an upper part, a middle part and a lower part, wherein a ring groove 201 for water flow to pass through is formed in the middle part, sealing rings 203 are arranged on the upper part and the lower part, the sealing rings 203 are used for sealing the gap between the valve core 2 and the inner cavity of the water tap, the water flow is prevented from entering the positions of the timing switch 3 and the spring 4 through the middle position of the valve core 2, meanwhile, in order to plug the water flow by the valve core 2, the sealing rings 203 positioned on the lower part of the valve core 2 are wide strip-shaped sealing rings 203, so that in the process that the valve core 2.

In order to facilitate the installation of the sealing ring 203, a sealing groove 202 is formed in the outer annular surface of the valve core 2 and used for clamping the sealing ring 203 in the sealing groove 202, so that the movement of the sealing ring 203 in the action process of the valve core 2 is limited; for the ribbon-shaped sealing ring 203 with a large width, in order to facilitate the installation of the ribbon-shaped sealing ring, an end cover 204 which can be disassembled by threads is arranged at the bottom of the valve core 2, when the ribbon-shaped sealing ring 203 needs to be installed or replaced, the end cover 204 is screwed off, the ribbon-shaped sealing ring 203 is sleeved into the position of the sealing groove 202 from the bottom of the valve core 2, and then the end cover 204 is screwed on, so that the assembling process of the ribbon-shaped sealing ring 203 can be conveniently completed.

The following describes a specific structure of the timer switch 3, which is formed by matching an existing timer 301 with a cam 302, the timer 301 can set time by a manual knob (the timer 301 is similar to a washing knob of a washing machine and a time setting knob of a microwave oven, and can be directly customized by a manufacturer), the cam 302 is fixed with a rotating shaft at the center, and the cam 302 is driven to rotate when the timer 301 automatically times. The specific control mode is as follows: the cam 302 is not contacted with the top of the valve core 2 under the normal condition, at this time, the valve core 2 is positioned at the upper position of the inner cavity of the water faucet shell 1 under the action of the spring 4, when the timer 301 is rotated manually, the cam 302 is driven to rotate, the cam 302 presses down the valve core 2, the valve core 2 moves downwards, the ring groove 201 reaches the position of the water inlet and the water outlet, at this time, the water inlet and the water outlet are communicated, the water faucet has water flow, and along with the continuous time, the timer 301 automatically rotates and recovers, simultaneously, the cam 302 is driven to rotate, the cam 302 is gradually separated from the valve core 2, the valve core 2 rises under the action of the spring 4 at the bottom of the valve core 2, the annular sealing ring 203 of the valve core 2 reaches the position of the water inlet and the water outlet to seal the water inlet and the water outlet, so that the water flow is cut off, in the process, the rotating time of the timer 301 can be, therefore, the purpose that the water faucet delays in any time period is achieved.

On the basis of the above mechanism, in order to facilitate the replacement of the spring 4, a spring hole 401 which is convenient for taking out and replacing the spring 4 is formed at the bottom of the faucet shell 1, and a spring cap 402 which is used for covering the spring hole 401 is connected to the corresponding position of the spring hole, when the spring 4 needs to be replaced, the spring cap 402 at the bottom of the faucet is only required to be opened, and then the spring 4 in the spring hole 401 is replaced.

The overall working principle of the invention is as follows;

the water tap is in a closed state in a normal state, at the moment, the valve core 2 is positioned at the upper part of the inner cavity of the shell 1, the water inlet pipe and the water outlet pipe are blocked by the strip-shaped sealing ring 203, and water flow is interrupted;

when water needs to be used, the timer 301 is manually rotated, the central shaft of the timer 301 drives the cam 302 to rotate, and the protruding part of the cam 302 presses down the valve core 2 when the cam 302 rotates, so that the position of the annular groove 201 in the middle of the valve core 2 reaches the positions of the water inlet pipe and the water outlet pipe, at the moment, the water inlet pipe and the water outlet pipe are communicated, and the water tap discharges water;

in the process of water flow, the timer 301 continuously rotates until the timer recovers, meanwhile, the cam 302 is driven to rotate, the protruding part of the cam 302 can gradually separate from the valve core 2, the valve core 2 rises under the action of the spring 4 at the bottom of the valve core until the belt-shaped sealing ring 203 at the lower part seals the water inlet and outlet pipe, and the water flow stops;

in the process, the set time of the timer 301 can be artificially defined, so that the time interval for returning after the valve core 2 is pressed down is defined, the water flow circulation time is further determined, and thus, the function of delaying in any time period is realized.

The technical solutions described above only represent the preferred technical solutions of the present invention, and some possible modifications to some parts of the technical solutions by those skilled in the art all represent the principles of the present invention, and fall within the protection scope of the present invention.
