Description

Touch faucet

The invention relates to a faucet, in particular to a touch faucet for switching water by pressing and touching.

The water-saving valve of early infrared induction has been developed in many patented technical literatures because of its high cost, complicated structure and high failure rate, and the development of touch-type water-saving valves, water-saving devices or water-saving switches. For example, the non-self-closing water-saving valves disclosed in the Republic of China certificate numbers M432670 and I228578, and the self-closing water-saving valves disclosed in the Republic of China certificate numbers I369459, M452280 and M382408. The common feature of the water saving valve is that it can be installed at the water outlet of the faucet, and both have an actuating element protruding below the water saving valve for the user to be moved upward and displaced into a rod shape, when the faucet is opened In the state, as long as the user touches the actuating element upwards, the water saving valve can be opened, so that the water flows through the water saving valve, and then the water is sprayed downward, and the internal structure design of the water saving valve can be used to save water. The function.

The difference between the above-mentioned non-closed water-saving valve and the self-closing water-saving valve is that the non-self-closing water-saving valve must also be activated to close the water stop function by touching the actuating element again in the water discharge state. The self-closing water-saving valve can automatically close the water-stopping valve after a period of water discharge by the gradual action of the water pressure.

A water-saving valve similar to that disclosed in the above-mentioned patent documents can also be seen on the market, for example, one touch 3M water-saving valve series which has been widely adopted by many users in the Taiwan market. The product can be installed at the water outlet of a general faucet, and the water can also be switched by a push-type touch operation.

Although the above water saving valve has the advantages of convenient installation operation, water saving and simple structure, the user must directly touch the actuating element of the water saving valve, which also becomes the biggest disadvantage, because when the user touches the actuating element, It means that the dirt on the hand is simultaneously contaminated on the actuating element. From the above patent documents and existing products, it is clear that the water flowing through the water valve of the province is usually flushed and flows through the actuating element to make it dirty. As the water flow is washed away, it pollutes the water. Therefore, these water-saving valves cannot be used in certain water environments because they cannot pass the relevant regulations on water sanitation in some countries.

The switch water system of the traditional faucet controls the water output by one hand to drive the water shaft, or adjusts the temperature of the water outlet. However, the operation control of the mandrel is driven by the handle, and the operation agility and convenience are affected due to the large stroke. . In addition, its operating space is large, if it is too close to the wall or the space is narrow, it is not conducive to installation. The handle area is usually not placed in the operating range of the handle, so the space available for use is greatly limited. The control structure of the handle and the mandrel also affects the aesthetics and texture of the design, which is not conducive to enhancing the added value of the product.

The present invention provides a touch faucet comprising a faucet body having a water inlet end, a water outlet end, and a water flow passage between the water inlet end and the water outlet end; a positioning cylinder holder fixed to the faucet The water outlet end of the body is provided with at least one water passing hole and a through hole; a water saving valve is disposed between the water outlet end of the faucet body and the positioning cylinder seat, and an operating valve stem is disposed thereon. Being displaced to activate the water saving valve to allow water to pass through the water saving valve; an actuating rod having a top position limited to the inside of the positioning cylinder seat, and a a sliding rod portion connected to the top position and accessible from the through hole of the positioning cylinder seat; the operating rod can be driven to actuate the displacement of the operating valve stem of the water saving valve; a pressing cover having An end wall, a surrounding wall extending from the end wall, and an inner space defined between the end wall and the surrounding wall; the end wall and the slide portion of the actuating rod Interlocking with each other; the surrounding wall and the positioning cylinder seat are slidably sealed with each other; the pressing cover can define a water-passing chamber together with the positioning cylinder and the actuating rod to communicate the water a hole; the water wall of the surrounding wall is further provided with a water outlet to communicate with the water passing chamber.

The present invention also provides a touch faucet comprising: a faucet housing having a mounting chamber having a mounting opening at a top end thereof; a temperature control valve mountable from a top end of the faucet housing Connected to the installation chamber, having a water inlet portion for the inflow of cold and hot water, a mixing chamber for mixing the cold and hot water in a predetermined ratio to form a mixed water, and one for the a water outlet portion from which the mixed water flows out; a water saving valve can be fixed to the water outlet portion of the temperature control valve, and an operating valve stem is disposed thereon, which can be touched and displaced to open the water saving valve from the mixing The mixed water of the chamber passes through the water saving valve and flows out from the water outlet portion; a pressing button has an actuating portion that can penetrate into the water outlet portion of the temperature control valve and can be pressed along the water outlet portion An axis X displacement to sense the displacement of the operating valve stem of the water saving valve.

The touch faucet provided by the invention is installed in a faucet with or without a temperature adjustment function by using a touch type water saving valve, and is provided with a pressing cover or a pressing button which can be touched by a user. The water valve of the province is touched, so that the faucet can have the function of touch-switching water, which can effectively replace the operation mode of the traditional mandrel and achieve the effect of water saving. More importantly, it is possible to prevent the user from directly touching the water saving valve. And to ensure that the water flow through the provincial water valve will not be contaminated, in line with the health and related countries' regulatory requirements. In addition, it is also possible to change the direction of the water outlet, which will result in different effluent and jet patterns compared to the water-saving valves that are commonly installed in the faucet outlet.
