Description

Technical Field

[0001] The invention relates to the technical field of valves, in particular to a convenient-to-use handheld showerhead and a stop valve thereof. Background Art

[0002] A stop valve is a valve that can control the flow of water. It is usually installed in the middle of hot and cold water pipes. The stop valve relies on blocking the hot and cold water inlet ends, and regulates the outflow of hot and cold water by the interception area of ​​the two water inlets, thereby controlling and cutting off the flow. The stop valve can be used in conjunction with a handheld shower in the bathroom to regulate the water temperature.

[0003] However, the existing stop valve needs to ensure that the hot and cold water inlet ends are on the same side or on opposite sides before it can be installed and used. When the position is wrong during the water pipe construction or there is a problem with the position of the reserved space for the water pipe, the two water inlet ends of the hot and cold water are prone to be distributed in a tilted state, and the two tilted water inlet ends do not conform to the pipe connection position of the stop valve, resulting in the problem that the stop valve and the two tilted water inlet ends are not easy to install and connect. The handheld showerhead connected to the stop valve hose can adjust the water outlet mode, and the showerhead can be rotated to adjust the showerhead spray position through the fixed seat. However, for people with larger body sizes, the length of the handheld showerhead is too short, and the showerhead sprays at 90 degrees to the handheld position. When people with larger body sizes use it, the showerhead cannot spray to the back due to the length of the arm movement, resulting in inconvenience in use. Summary of the invention

[0033] like Figures 1 to 7 As shown, the present invention proposes a stop valve, including a thermostatic mechanism 2, a flow pipe 3, a movable block 4 and a water diversion pipe 5, wherein the thermostatic mechanism 2 is arranged on a wall, the water diversion pipe 5 is arranged on the wall and connected to a water supply pipe, the flow pipe 3 is arranged on the left side of the thermostatic mechanism 2, two water diversion pipes 5 are provided, and are respectively connected to the upper and lower sides of the thermostatic mechanism 2, the movable block 4 rotates at the right end of the thermostatic mechanism 2, and a handle 29 is provided at the outer end of the thermostatic mechanism 2, and the rotation of the movable block 4 drives the handle 29 at the outer end of the thermostatic mechanism 2 to rotate;

[0034] The thermostatic mechanism 2 is provided with a movable mechanism 21, a round rod 22, a cut-off mechanism 23, a first water inlet pipe 24, a shell 25, a working spring 26, a piston 27 and a protective spring 28. The movable mechanism 21 and the first water inlet pipe 24 are respectively connected to the two water diversion pipes 5 corresponding to the pipeline. A first convex structure is provided on the inner side of the shell 25. The left end of the working spring 26 is fixed at the first convex structure on the inner side of the shell 25. The other end of the working spring 26 is arranged on the bearing on the outer side of the round rod 22. When the round rod 22 rotates to the left, the bearing is driven to compress the working spring 26. The protective spring 28 is arranged on the side of the piston 27. The left and right ends of the protective spring 28 are provided with sealing rings, and the sealing ring of the protective spring 28 is sealed and movable inside the shell 25. The handle 29 is arranged at the outer end of the round rod 22. The piston 27 is located on the outer side of the round rod 22, and the outer side of the piston 27 is sleeved on the inner side of the shell 25. When the round rod 22 rotates, the round rod 22 drives the piston 27 to rotate and translate in the shell 25.

[0035] The cut-off mechanism 23 is arranged on the outside of the round rod 22, and the outer sides of the left and right ends of the cut-off mechanism 23 correspond to the movable mechanism 21 and the water inlet end of the first water inlet pipe 24. Two screws are arranged on the outer side of the shell 25 corresponding to the movable mechanism 21, and the screws spirally push the movable mechanism 21 in the shell 25 and make the movable mechanism 21 press against the inner side of the shell 25. A first track groove is arranged inside the lower side of the shell 25. The first track groove is horizontally arranged corresponding to the movable mechanism 21. The movable mechanism 21 translates in the first track groove, and the inner side of the movable mechanism 21 is sleeved on the corresponding outer side of the cut-off mechanism 23.

[0036] Furthermore, the connection between the inside of the movable block 4 and the handle 29 is in a square state, which has the effect of enabling the movable block 4 to drive the handle 29 to rotate.

[0037] Among them, the movable mechanism 21 is provided with a rubber plate 211, a connecting block 212, a second water inlet pipe 213, an arc plate 214 and a threaded plate 215. The rubber plate 211 is attached to the inner side of the arc plate 214. The threaded plate 215 is connected to the arc plate 214 through the connecting block 212. The arc plate 214 is connected to the water diversion pipe 5 through the second water inlet pipe 213. The threaded plate 215 is sleeved on the outside of the cut-off mechanism 23. The arc plate 214 moves in the first track groove in the shell 25. When the arc plate 214 moves left and right, the threaded plate 215 is sleeved on the outside of the cut-off mechanism 23 and pulls it to move horizontally.

[0038] Among them, the cut-off mechanism 23 is provided with a sliding rod 231, a circular hole 232, a cylindrical block 233, a circular ring plate 234 and a hollow tube 235. The four circular holes 232 are arranged in a ring in the cylindrical block 233. The circular ring plate 234 moves on the inside of the shell 25. When the round rod 22 rotates and moves, the cylindrical block 233 on the outside of the round rod 22 is driven to rotate and move, and the circular ring plate 234 at the right end of the cylindrical block 233 closes the first water inlet pipe 24.

[0039] In addition, a second protrusion structure is provided at the left end of the hollow tube 235. The second protrusion structure moves by friction on the inner side of the shell 25, and the second protrusion structure moves to the right to the connecting block 212 to form an annular space that blocks the second water inlet pipe 213, and the size of the annular space is adjusted as the second protrusion structure moves.

[0040] In addition, the six sliding rods 231 are arranged in a circular array on the inner side of the hollow tube 235, and the outer side of the cylindrical block 233 is provided with a second track groove corresponding to the sliding rod 231. The sliding rod 231 translates in the second track groove. The outer side of the hollow tube 235 is provided with a spiral pattern. When the cut-off mechanism 23 rotates following the round rod 22, the hollow tube 235 rotates on the inner side of the threaded plate 215.

[0041] In the present invention, the cold and hot water of the first water inlet pipe 24 are respectively introduced into the first water inlet pipe 24 and the second water inlet pipe 213 in the movable mechanism 21 from the two water guide pipes 5, and the movable block 4 is manually rotated, and the movable block 4 drives the handle 29 to rotate, so that the handle 29 drives the round rod 22 to rotate, and the piston 27 is threadedly rotated and translated on the inner side of the shell 25, so that the round rod 22 moves while rotating. At this time, the round rod 22 compresses the working spring 26, and under the rotation and movement of the round rod 22, the circular plate 234 in the cut-off mechanism 23 moves frictionally in the shell 25, so the circular plate 234 is located to intercept and block the inlet end of the first water inlet pipe 24, and the cylindrical block 233 follows the round rod 22. During rotation and translation, the cylindrical block 233 drives the hollow tube 235 to rotate through the sliding rod 231, and causes the hollow tube 235 to rotate on the threaded plate 215. At the same time, the second protrusion structure of the hollow tube 235 rubs in the shell 25. After the hollow tube 235 moves to the corresponding position of the second water inlet pipe 213, the water flowing therein is intercepted. Therefore, the movement of the round rod 22 drives the annular plate 234 and the hollow tube 235 to intercept the water flowing in the first water inlet pipe 24 and the second water inlet pipe 213 respectively. When the annular plate 234 moves to the left, the opening of the first water inlet pipe 24 is increased, and the opening of the hollow tube 235 to the second water inlet pipe 213 is reduced, thereby achieving the effect of adjusting the water output of the two water diversion pipes 5.

[0042] In the present invention, before the water guide pipe 5 is connected to the thermostatic mechanism 2, the first water inlet pipe 24 is used as a reference point, and the second water inlet pipe 213 is moved according to the position of one of the water guide pipes 5, thereby pushing the arc plate 214 to move in the first track groove in the shell 25, thereby driving the threaded plate 215 connected to the connecting block 212 to move horizontally. At this time, the threaded plate 215 is driven to move horizontally through the spiral pattern on the outside of the hollow tube 235, and pulls the sliding rod 231 on the inside of the hollow tube 235 to move horizontally in the second track groove corresponding to the outside of the column block 233, so that the movement of the arc plate 214 does not affect the rotation of the column block 233 to drive the hollow tube 235. The core tube 235 rotates with the threaded plate 215, and after the arc plate 214 moves, the two screws on the outside of the shell 25 move in the inner thread of the shell 25, and the screws push the outside of the arc plate 214 inward and make the rubber plate 211 press against the first track groove of the shell 25 to form a seal, thereby achieving the fixing effect after the arc plate 214 moves, so as to adjust the position according to the pipe connection between the lower end of the second water inlet pipe 213 and one of the water diversion pipes 5, so as to facilitate the horizontal connection of the thermostatic mechanism 2 with its pipe when the two water diversion pipes 5 are inclinedly distributed, thereby preventing the problem that it is difficult to install and connect the thermostatic mechanism 2 when the two water diversion pipes 5 are inclined.

[0043] Based on the above-mentioned stop valve, the present invention further proposes a convenient hand-held shower, comprising a sprayer 1, a hose 6 and a fixing seat 7, wherein the hose 6 is connected to the lower end of the flow pipe 3, and the fixing seat 7 is arranged on the wall, the sprayer 1 is engaged in the fixing seat 7, and the lower end of the sprayer 1 is connected to the hose 6, the sprayer 1 is provided with a limit plate 11, a spray head 12, a sealing member 13, a rotating mechanism 14, a water-passing plate 15, a telescopic tube 16 and a water spraying plate 17, wherein the water spraying plate 17 is arranged on the sprayer Inside the head 12, there are two limit plates 11, which are symmetrically arranged on the side of the spray head 12, and the limit plates 11 are limited inside the water-passing plate 15. The rotating mechanisms 14 arranged on both sides of the spray head 12 slide at the corresponding positions on the inner side of the water-passing plate 15. Both ends of the telescopic tube 16 are sealed and connected between the spray head 12 and the inside of the water-passing plate 15. The outer end of the sealing member 13 is arranged at the pipe connection between the outer end of the water-passing plate 15 and the hose 6. When the spray head 12 is stretched outward, the spray head 12 stretches and extends the telescopic tube 16.

[0044] In addition, the right end of the spray head 12 is a convex structure, which corresponds to the concave structure of the left end of the water-passing plate 15. The sealed channel inside the water-passing plate 15 is connected to the spray head 12 through the telescopic tube 16. The water flows from the hose 6 into the water-passing plate 15, and flows through the telescopic tube 16 into the spray head 12, and the water is sprayed out at the water spray plate 17.

[0045] Among them, the limiting plate 11 is provided with a plastic plate 111, a slide groove 112 and a connecting plate 113, a semicircular bar is provided on the outer side of the connecting plate 113, and a corresponding third track groove is provided on the inner side of the plastic plate 111 corresponding to the semicircular bar. The semicircular bar is limited by the third track groove on the inner side of the plastic plate 111, and the slide groove 112 is provided on the inner side of the water passing plate 15 corresponding to the rotating mechanism 14. When the connecting plate 113 is pulled outward by the spray head 12, the semicircular bar outside the connecting plate 113 squeezes the inner side of the plastic plate 111 and causes the plastic plate 111 to elastically deform on the side of the water passing plate 15.

[0046] The rotating mechanism 14 is provided with a rotating rod 141, a ball block 142, a cylinder 143 and a slider 144. A layer of rubber material is provided on the inner side of the cylinder 143. The ball block 142 is arranged in a ring array on the rubber material on the inner side of the cylinder 143. The slider 144 slides correspondingly in the slide groove 112. The spray head 12 rotates with the outer side of the rotating rod 141, and the rotating rod 141 rotates and presses the ball block 142.

[0047] In addition, the outer side of the rotating rod 141 is an arc-shaped structure, and the arc-shaped structure corresponds to the spaced circular array arrangement of the two ball blocks 142. When the rotating rod 141 is rotated by the spray head 12, the arc-shaped structure on the outer side of the rotating rod 141 is driven to squeeze the ball block 142 laterally, and the rubber material on the inner side of the cylinder 143 elastically blocks the ball block 142 from being pressed, so that when the rotating rod 141 rotates an arc angle, it is elastically blocked by the rubber material, and then the rotating rod 141 is limited when it rotates with the spray head 12.

[0048] In the present invention, after being mixed and temperature-controlled in the constant temperature mechanism 2, the hot and cold water flows from the circulation pipe 3 to the hose 6, and the mixed water flows from the water-passing plate 15 to the telescopic tube 16 to the spray head 12 at the left end, and the water is sprayed out through the water spraying plate 17. When the sprayer 1 is held, the spray head 12 is stretched outward, so that the spray head 12 pulls the telescopic tube 16 to extend and extend, and then the spray head 12 drives the semicircular strips on the outer side of the connecting plate 113 to squeeze the plastic plate 111, so that the semicircular strips are pressed outward at the third track groove position on the inner side of the plastic plate 111. At this time, the plastic plate 111 moves elastically outward and provides space for the movement of the connecting plate 113. After the spray head 12 is extended, the semicircular strips on the outer side of the connecting plate 113 are on the third track groove on the inner side of the plastic plate 111. The position of the groove is limited and fixed, and when the spray head 12 is stretched and extended outward, the cylinder 143 on the outside of the rotating rod 141 is driven to move, and the slider 144 is slid and translated in the slide groove 112 at the corresponding position on the inner side of the water-passing plate 15. After the extension is completed, the spray head 12 can be rotated to make the slider 144 block the rotation of the cylinder 143, so that the arc structure on the outside of the rotating rod 141 squeezes the ball block 142 and rotates. After the rotation of the rotating rod 141 is completed, the rubber material on the inside of the cylinder 143 elastically presses the ball block 142, and the ball block 142 is limited and fixed to the arc structure on the outside of the rotating rod 141. Through the extension and rotation of the spray head 12, it is convenient for users to adjust the length and angle according to needs, extend the handheld length, and facilitate users to spray the back.

[0049] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
