Description

Faucet water flow adjustment prompt structure (2)

The invention relates to a faucet structure, in particular to a faucet water supply flow adjustment prompting structure.

Press, the faucet is an essential device in people's daily life. It is used to control the size and switch of the water flow. It is mainly used in bathroom and kitchen equipment. The conventional faucet has a faucet body, and the faucet body is provided with a water outlet pipe. A water control valve is installed on the faucet body, and a handle is installed on the faucet body. The handle is connected with the water control valve, and the water supply flow of the faucet can be adjusted by rotating the handle to link the water control valve.

However, when this conventional faucet is used, its water supply flow rate does not have a segmented adjustment function, and it is difficult to effectively control the rotation angle of the handle. Most of the time, it is first turned to the maximum water output state, and then adjusted back to the required flow rate. Not only is it inconvenient to use, but it also easily causes unnecessary waste of water resources during the adjustment process, resulting in poor practicality.

In view of the above-mentioned shortcomings of conventional faucets, the creator thought about the idea of creation. After many discussions and trial samples, and many revisions and improvements, he came up with this creation.

The handle 40 is provided with a set of connection holes 41 , and the set of connection holes 41 is engaged and locked with the assembly section 221 at the upper end of the control valve stem 22 , so that the handle 40 is linked with the control valve stem 22 and can be driven by the handle 40 The control valve stem 22 rotates.

During use, as shown in Figures 9 and 10, the handle 40 drives the control stem 22 of the water control valve 20 to rotate, and the control stem 22 links the rotating member 28 to disengage the slot 281 at the bottom of the rotating member 28. The locating piece 27 is pushed downward by the rotating member 28 to compress the elastic member 26, and the rotating member 28 continues to rotate until the other slot 281 at the bottom corresponds to the convex engaging portion 271 of the positioning piece 27. , the positioning piece 27 is pushed upward by the elastic member 26, so that another slot 281 at the bottom of the rotating member 28 engages with the protruding portion 271 of the positioning piece 27 for positioning. In this way, a segmented positioning function is formed, which is convenient for use. The user adjusts the water supply flow of the faucet and provides the user with adjustment prompt effects.

When you want to adjust the water flow rate of the faucet, as shown in Figure 11, the handle 40 drives the control stem 22 of the water control valve 20 to rotate to the first position, and the water stopper 24 is controlled to separate from the water inlet of the faucet body 10 hole 112, allowing the water inlet hole 112 to conduct, and at the same time, the lifting member 23 rises, and the positioning piece 27 is first pushed downward by the rotating member 28 to compress the elastic member 26, so that the slot 281 at the bottom of the rotating member 28 is separated from the protrusion of the positioning piece 27. When the rotating member 28 rotates to a predetermined position, the positioning piece 27 is pushed upward by the elastic member 26, so that the protruding clamping portion 271 of the positioning piece 27 engages with the corresponding slot 281 of the rotating member 28. , the first sound is emitted, providing a prompt to open the first section of water outlet, so that at least one first water outlet hole 215 is connected, at least one second water outlet hole 216 and at least one third water outlet hole 217 are blocked by the lifting member 23, thereby allowing water flow The water enters the valve chamber 11 through the water inlet hole 112 of the faucet body 10, flows out through at least one first water outlet hole 215 of the valve seat 21, and water is discharged from the water outlet of the faucet body 10 with a small water supply flow rate.

When you want to adjust the flow rate of water in the faucet, as shown in Figure 12, the handle 40 drives the control stem 22 of the water control valve 20 to rotate to the second position, and the lifting member 23 is controlled to continue to rise. Through the positioning piece 27 The elastic member 26 is first pushed downward by the rotating member 28 so that the slot 281 at the bottom of the rotating member 28 is separated from the protruding portion 271 of the positioning piece 27. When the rotating member 28 rotates to a predetermined position, the positioning piece 27 is elastically pressed again. The member 26 is pushed upwards, so that the protruding portion 271 of the positioning piece 27 is engaged with the corresponding slot 281 of the rotating member 28, and a second sound is emitted, providing a prompt to start the second stage of water discharge, so that at least one first The water outlet hole 215 and at least one second water outlet hole 216 are connected, and the at least one third water outlet hole 217 is blocked by the lifting member 23, so that the water flow enters the valve chamber 11 through the water inlet hole 112 of the faucet body 10, and passes through at least one of the valve seat 21. A first water outlet hole 215 and at least a second water outlet hole 216 flow out, and water is discharged from the water outlet of the faucet body 10 at a medium water supply flow rate.

When it is desired to adjust the maximum water flow rate of the faucet, as shown in Figure 13, the handle 40 drives the control stem 22 of the water control valve 20 to rotate to the third position, and the lifting member 23 is controlled to continue to rise. Through the positioning piece 27 The elastic member 26 is first pushed downward by the rotating member 28 so that the slot 281 at the bottom of the rotating member 28 is separated from the protruding portion 271 of the positioning piece 27. When the rotating member 28 rotates to a predetermined position, the positioning piece 27 is elastically pressed again. The member 26 is pushed upwards, so that the protruding portion 271 of the positioning piece 27 is engaged with the corresponding slot 281 of the rotating member 28, and a third sound is emitted to provide a prompt for opening the third section of water outlet, so that at least one first The water outlet hole 215, at least one second water outlet hole 216, and at least one third water outlet hole 217 are all connected, so that the water flow enters the valve chamber 11 through the water inlet hole 112 of the faucet body 10, and passes through at least one first water outlet of the valve seat 21. The hole 215, at least one second water outlet hole 216 and at least one third water outlet hole 217 flow out, and water is discharged from the water outlet of the faucet body 10 with a large water supply flow rate.

From the structure of the above specific embodiment, the following benefits can be obtained:

1. The faucet water supply flow adjustment prompt structure of the present invention can be positioned by engaging the plurality of slots 281 of the rotating member 28 with at least one protruding catch portion 271 of the positioning piece 27 when the control valve stem 22 is rotated to control the water outlet of the faucet, thereby providing a precise positioning. The segmented positioning function and adjustment sound prompts, combined with the plurality of water outlets (at least one first water outlet 215, at least one second water outlet 216 and at least one third water outlet 217) located at different heights, facilitate easy and quick adjustment by the user. The required water output can improve the convenience of use and save water.

2. The water supply flow adjustment prompt structure of the faucet of this invention, the water control valve 20 and the lock cover 30 can be directly applied to existing faucets, taking into account both practicality and cost.
