Description

A kind of safe tap water tap

technical field

The utility model belongs to the field of safety water faucets, in particular to a safety water faucet.

Background technique

The faucets used at present are all instant-on and ready-to-use types. Water will flow out as soon as you turn it on, and stop the water as soon as you turn it off. In many occasions where tap water is used, running water often occurs. The main reason is that the faucet is usually turned on when there is no water. This not only wastes water resources and causes economic losses, but also brings troubles to users and the residents downstairs, and affects the relationship between neighbors. Therefore, there is a need for a safety faucet that can avoid running water, that is, when there is water, it can be operated normally and is no different from an ordinary faucet; when there is no water, the faucet will automatically close and return to the original position;

At present, there are faucets with this function in the market, but the work is not accurate, and there are requirements for use, such as sitting and standing installation, relying on gravity, etc.; some need to be connected to electricity, and the sensor senses whether there is water, and then controls the lock wait.

Contents of the invention

The purpose of this utility model is to provide a safe running water faucet to solve the above-mentioned problems in the prior art.

In order to achieve the above purpose, the utility model provides a safe tap water faucet, comprising:

Water inlet, valve body and water outlet;

Wherein, the valve body is arranged between the water outlet and the water inlet;

The valve body includes a valve shell and a valve spool, the valve spool is located inside the valve shell, the valve spool is connected to the upper inner surface of the valve shell through a return spring, and a pressing handle is arranged above the valve shell , the pressing handle is connected to the valve spool through a connecting rod, and a locking structure is arranged on the right side of the valve spool.

Optionally, the locking structure is an integral right-angle bending structure, and a fixed shaft is arranged at a corner point of the locking structure, and the locking structure moves through the fixed shaft.

Optionally, the return spring is used to make the valve core move downward.

Optionally, the inner surfaces of the left side of the valve core and the left side of the valve casing are frosted and contact each other.

The technical effect of the utility model is:

The design of the safe tap water faucet provided in the utility model can be operated normally when there is water, which is no different from the ordinary faucet; when there is no water, it will automatically close and return to the original position; The handle of the valve body can be adjusted arbitrarily; at the same time, the utility model does not use electrical control to complete it, but is completed by a simple mechanical mechanism; the utility model has no requirements for the installation position and direction, and does not need to be connected to electricity, etc., with low cost and reliable operation , Easy to install, has a good promotion prospect.

Detailed ways

It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

Embodiment one

As shown in Figures 1-2, a safe tap water tap is provided in this embodiment, including:

Water inlet, valve body and water outlet;

Wherein, the valve body is arranged between the water outlet and the water inlet;

The valve body includes a valve casing 2 and a valve spool 5, the valve spool 5 is located inside the valve casing 2, the valve spool 5 is connected to the upper inner surface of the valve casing 2 through a return spring 3, the A pressing handle 1 is arranged above the valve housing 2, and the pressing handle 1 is connected with the valve core 5 through a connecting rod, and a locking structure 4 is arranged on the right side of the valve core 5.

It can be implemented that the locking structure 4 is an overall right-angle bending structure, and a fixed shaft is arranged on a corner point of the locking structure 4, and the locking structure 4 moves through the fixed shaft.

It can be implemented that the return spring 3 is used to make the valve core 5 have a tendency to move downward.

It can be implemented that the inner surfaces on the left side of the valve core 5 and the left side of the valve housing 2 are frosted surfaces and are in contact with each other.

When the push handle 1 is lifted, as shown in Figure 2, the valve body is in an open state, and when the push handle 1 is pressed, the valve body is in a closed state; Can be changed by pressing handle 1;

The locking structure 4 is a device used to maintain the state of the valve spool 5. When there is water in the pipeline, the valve spool 5 is in an open state, and the flow of water will generate a leftward force on the locking structure 4, locking The corner point of the structure 4 is provided with a fixed axis, and the locking structure 4 moves around the fixed axis, and is stationary or tilted. When it is stationary, there is no force, and the flow of water will generate a leftward force on the locking structure 4. At this time The locking structure 4 will be tilted, so that there will be an upward force F2 on the valve core 5, which is opposite to the force F1 of the spring acting on the valve core 5; the left contact part of the valve core 5 and the valve body is a frosted surface , to increase its friction force, when there is water, the water has a leftward pressure on the valve core 5, so that the valve core 5 and the valve body have a friction force F3, when the valve body is in the position shown in Figure 2, the The direction of the friction force F3 is upward, opposite to the spring force; in summary, it can be seen that F1=F2+F3, so that when there is water, the water output can be arbitrarily controlled through the safety faucet. When there is no water, there is no leftward pressure on the valve spool 5, so there is no friction force F3, and at the same time, the locking structure 4 has no water force to the left, so there is no upward force F2 on the valve spool 5 ; To sum up, when there is no water in the pipeline, F2=0, F3=0, so after the handle is lifted, the valve body will automatically return to its original position (that is, the closed state) under the action of F1 force. It can be seen that the valve body can operate normally when there is water, and when there is no water, the valve body automatically returns to the original position (closed state), so as to prevent the occurrence of water leakage.

The safe tap water faucet provided in the utility model can operate normally when there is water, which is no different from the ordinary faucet; when there is no water, it will automatically close and return to the original position; The body presses the handle 1 to adjust arbitrarily; at the same time, the utility model does not use electrical control to complete, but is completed by a simple mechanical mechanism; the utility model has no requirements for the installation position and direction, and does not need to be connected to electricity, etc., low cost and easy to operate The utility model has the advantages of reliability, convenient installation and good promotion prospect.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any person familiar with the technical field can easily think of All changes or replacements should fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope of the claims.
