Description

Water saving valve

This creation relates to a water saving valve, and more particularly to a water saving valve installed in a faucet or a water outlet.

The water outlet of the faucet installed on the general sink or the counter is separated from the switch, so that the water outlet of the faucet is located above the sink of the sink or the counter, and the switch is located at the edge of the sink. Therefore, when the user washes his hand, he must move the hand that is still full of water to the edge of the sink to operate the switch, close the faucet, and wet the table of the sink or the counter.

For example, there is a faucet on the market, the operating mechanism is a pressing portion, and the pressing portion is disposed at the top of the faucet, and the water switch can be controlled when the pressing portion is pressed downward. However, in addition to the aforementioned disadvantages of easily wetting the sink top, the switch design of the faucet must be pressed or pressed in a specific direction to be opened or closed, so that the elderly or the height is too small to be hooked to the top of the faucet. It is difficult for children, etc., to generate enough force to push the pressing part, making pressing the switch a very difficult behavior.

Therefore, many people now install a water valve at the outlet of the faucet to allow the user to push the water valve from the bottom up to control the opening and closing of the faucet. This will not only wet the sink, but also facilitate the switching of water. However, the pressing direction of such a water valve is still limited, and it is necessary to press from bottom to top to switch, which is inconvenient to use. In addition, since the water is closed from the bottom up, the hand is still under the water outlet and will be in contact with the water outlet, and it will be more likely to be contaminated when the water is opened and the water is closed. Dirt is therefore still a health concern.

In view of this, it is an urgent problem to be solved in the industry to propose a better improvement solution.

The main purpose of this creation is to propose a water-saving valve that can be switched not only from the bottom to the top, but also when the vehicle is pushed in the lateral direction, achieving a convenient and labor-saving effect.

Therefore, the advantage of this creation is that the water saving valve of the present invention provides two different switching water actuating mechanisms, and the user can choose to push the water saving valve vertically or push the water saving valve horizontally. In this way, not only can the hand repeatedly touch the dirt-stained part of the water-saving valve, but also the water can be switched in the most relaxed position according to the needs of use. In addition, the creation also assists the lateral or longitudinal movement of the traverse ring and the longitudinal member through the ring groove and the guiding rib to minimize the resistance and make the user less laborious.

The ratchet teeth 1222 of the operating member 122 are accommodated in the guide groove 411 of the valve seat 121 so as to be vertically movable, so that the ratchet teeth 1222 of the operating member 122 are spaced apart from the ratchet teeth of the valve seat 121.

The abutting rod 123 is received in the through hole 1221 of the operating member 122. The abutting bar 123 forms a plurality of side flaps 1231 and a receiving groove 1232. The side flaps 1231 extend radially from the upper end of the abutting rod 123, so that they can be selectively engaged with the ratchet teeth 1222 of the operating member 122 or the ratchet teeth of the valve seat 121. The accommodating groove 1232 is located at the upper end surface of the urging rod 123. The lower end of the valve stem 124 is received in the receiving groove 1232 of the abutting rod 123, and the upper end is connected to the buffer assembly 13. The cushioning assembly 13 can be used to control the valve body 10 to open or shut off water. The elastic member 125 is connected at one end to the outer casing 111 and at the other end to the operating member 122 to move the operating member 122 downward.

The positioning ring 20 is fixed to the lower end of the outer casing 111 of the valve body 10, and is formed with a ring groove 200, and the ring groove 200 is located on the outer side of the positioning ring 20. Specifically, the positioning ring 20 is formed with a first body 21 and at least a second body 22. The first sheet body 21 has an annular sheet body and is disposed on the outer circumferential surface of the positioning ring 20, and the upper side surface of the first sheet body 21 abuts against the valve body 10.

However, in this embodiment, the number of the second body 22 is a plurality of small pieces, and the positioning ring 20 is disposed on the positioning ring 20. The outer peripheral faces are arranged in a ring shape and spaced apart from each other. The second sheet 22 is disposed at a lower end of the positioning ring 20 and spaced apart from the first sheet 21 . Thereby, the ring groove 200 is formed between the first sheet body 21 and the second sheet body 22.

In the present embodiment, the positioning ring 20 is further formed with a plurality of vent holes 23 extending longitudinally through the positioning ring 20, and the lower ends of the vent holes 23 are aligned with each other between the second sheets 22.

The traverse ring 30 is laterally movably sleeved on the ring groove 200 of the positioning ring 20, that is, the inner diameter of the traverse ring 30 is larger than the outer diameter of the ring groove 200, so that there is a gap between the traverse ring 30 and the ring groove 200. Available for traverse The ring 30 moves laterally. At the same time, the traverse ring 30 is sandwiched between the first piece 21 and the second piece 22, and the outer diameters of the first piece 21 and the second piece 22 are larger than the inner diameter of the traverse ring 30 to prevent The traverse ring 30 falls off. The traverse ring 30 is formed with at least one guide rib 31, and at least one guide rib 31 is located on the outer side of the traverse ring 30. In the present embodiment, the number of the guiding ribs 31 is plural, which extends in the circumferential direction and is spaced apart from each other.

The longitudinal member 40 is sleeved on the traverse ring 30 in a longitudinally movable manner. The longitudinal member 40 can have a longitudinal shifting ring 41 and a mesh plate 42.

The longitudinal ring 41 is longitudinally movably sleeved on the traverse ring 30, and the longitudinal ring 41 is formed with at least one guiding groove 411, and at least one guiding groove 411 is located on the inner ring wall surface of the longitudinal ring 41. In the present embodiment, the number of the guide grooves 411 is equal to the number of the guide ribs 31, and the guide ribs 31 are accommodated in the guide grooves 411 so as to be longitudinally movable, respectively. In other words, the guiding grooves 411 are also arranged at intervals from each other.

In the present embodiment, the longitudinally-moving ring 41 of the longitudinal member 40 is further formed with a plurality of stopping portions 412 respectively located at the upper ends of the guiding grooves 411. The stopper portion 412 extends toward the center of the longitudinal movement ring 41 to form a hook shape, so that the guide rib 31 can be prevented from continuing to move upward when the guide rib 31 is moved to the uppermost end of the guide groove 411, thereby causing the longitudinal movement ring 41 to be self-aligned on the traverse ring 30. Fall off.

The stencil 42 is fixed in the longitudinal ring 41 and has a tapered curved surface 421 and a plurality of first flow holes 422. The tapered curved surface 421 of the stencil 42 is located on the upper side of the stencil 42. The tapered curved surface 421 of the stencil 42 is complementary in shape to the tapered curved surface 1223 of the valve body 10 operating member 122, one of which is a concave curved surface and the other is a convex curved surface. In the present embodiment, the tapered curved surface 421 of the mesh plate 42 is concave, and the tapered curved surface 1223 of the operating member 122 is convex.

In the embodiment, the stencil 42 is formed with a plurality of first flow holes 422 distributed on the stencil 42 and distributed around the tapered curved surface 421 of the stencil 42; the longitudinal ring 41 is formed with a plurality of second flows. A hole 413 is distributed around the circumference of the longitudinal ring 41. The first flow hole 422 is a path through which the water flows when the valve body 10 is opened, and the second flow hole 413 is a path through which the air passes, so that the valve body 10 is opened for the air to flow in and the air and water are mixed to achieve a water saving effect.

When in use, the water saving valve of the present invention can be installed in the water outlet of the faucet A, and the faucet A can be kept in the water supply state, and the water-saving valve of the present invention can be used for boiling water or water shut-off. When the user wants to open the water, the stencil 42 can be pressed longitudinally from the bottom to the top, or the traverse ring 30 can be horizontally pushed horizontally, and the purpose of opening or closing the water-saving valve of the present invention can be achieved.

Please refer to FIG. 4 and FIG. 5. If the stencil 42 is pressed longitudinally from the bottom to the top, the tapered curved surface 421 of the upper surface of the stencil 42 pushes the tapered curved surface 1223 of the operating member 122 of the valve body 10, thereby driving the operating member 122 to move upward. When the operating member 122 moves upward, the abutting rod 123 and the valve stem 124 also move upward, and the abutting rod 123 is also rotated by the ratchet teeth 1222 of the operating member 122 and the ratchet teeth of the valve seat 121. The rod 123 and the valve stem 124 are fixed to the upper end. When the valve stem 124 is at the upper end, the valve stem 124 opens the buffer assembly 13 to allow water to flow through the buffer assembly 13 to complete the water opening action.

At this time, since the stencil 42 is fixed to the slewing ring 41, the stencil 42 and the slewing ring 41 move upward along the guide rib 31. Thereby, the resistance between the longitudinal shifting ring 41 and the traverse ring 30 is reduced, and the longitudinal relative movement is kept smooth, and the user only needs to overcome the gravity of the stencil 42, the longitudinal shifting ring 41, the operating member 122, and the elastic member 125. The elasticity can switch the water, which is very light and effortless.

Please refer to FIG. 4 and FIG. 6 next. Similarly, when the user horizontally pushes the traverse ring 30 horizontally, the traverse ring 30 drives the stencil 42 and the slewing ring 41 to move laterally, so that the tapered curved surface 421 of the upper side of the stencil 42 and the cone of the operating member 122 The curved surface 1223 also moves relatively laterally and pushes the operating member 122 upward. When the operating member 122 is moved upward, the valve stem 124 also opens the buffer assembly 13 to allow water to flow through the cushioning assembly 13 to complete the boiling action.

At this time, since the inner diameter of the traverse ring 30 is spaced from the outer diameter of the ring groove 200, the traverse ring 30 can be laterally moved on the ring groove 200. At the same time, the traverse ring 30 is disposed between the first piece 21 and the second piece 22 to minimize the resistance of the traverse ring 30 in the lateral movement, so that the user can effortlessly open the water horizontally.

In summary, the water-saving valve of the present invention provides two different switching water actuating mechanisms, and the user can choose to push the water-saving valve longitudinally or horizontally to push the water-saving valve, which not only avoids repeated touches of the hand. To the part of the water-saving valve that is contaminated with dirt, the water can be switched in the most relaxed position according to the needs of use. In addition, the present invention also assists the lateral or longitudinal movement of the traverse ring 30 and the longitudinal member 40 through the ring groove 200 and the guiding ribs 31 to minimize the resistance and make the user less laborious.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way. Although the present invention has been disclosed above in the preferred embodiment, it is not intended to limit the present invention, and is not in any technical field. A person skilled in the art can make some modifications or modifications to equivalent embodiments by using the above-disclosed technical contents without departing from the technical scope of the present invention. The technical essence of the present invention, any simple modifications, equivalent changes and modifications made to the above embodiments are still within the scope of the present technical solution.
