Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of water valve adjustment, in particular to a water regulating valve. BACKGROUND

[0002] The existing bath bucket hot water control system usually adopts a conventional manual water valve (such as a rotary or wrench type valve) to adjust the water temperature and flow. Such valve has simple structure and direct operation, and is generally opened and closed by rotating or pulling the handle. However, since such valve lacks safety protection design for children, children may easily rotate the valve handle due to curiosity or misoperation, resulting in accidental release of high-temperature hot water into the bath bucket. Especially during the bath bucket storage or cleaning process, if the guardian leaves for a short time, the child has a high risk of scalding when touching the valve.

[0003] In the prior art, some water valve products try to limit unauthorized operation by adding a locking device (such as an electronic password lock), but such scheme has the following defects: the electronic lock relies on power supply and circuit maintenance, has high cost and insufficient reliability, the electronic lock usually needs to be installed and used with the corresponding brand of water valve, is difficult to be compatible with the general valve accessories on the market, and has high promotion cost. On the other hand, some families use physical shielding (such as valve protection cover) or remove the handle to reduce the probability of children's accidental touch, but such temporary measures cannot meet the normal use requirements, and have problems such as easy falling off of the shielding device and poor operation experience.

[0004] Therefore, in order to solve the above technical problems, the water regulating valve is provided. UTILITY MODEL CONTENTS

For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0034] As Figure 1 and Figure 2As shown, a water regulating valve 10 comprises a valve body 100, a sleeve 200, and a screwing assembly 300, the sleeve 200 is rotationally provided with a rotating core 400, one end of the rotating core 400 is detachably connected with a valve core 110 of the valve body 100, the other end of the rotating core 400 is provided with a plurality of circumferentially distributed first inclined teeth 500, the screwing assembly 300 comprises a rotating column 310, a sliding core 320, and an elastic member 330, the rotating column 310 is rotationally provided on the sleeve 200, the sliding core 320 is axially slidably provided in the rotating column 310, the end of the sliding core 320 is provided with a plurality of circumferentially distributed second inclined teeth 340, the elastic member 330 is sleeved on the sliding core 320, and the elastic member 330 is in abutment with the rotating column 310 and the sliding core 320 respectively, the elastic member 330 is used for pushing the sliding core 320, so that the second inclined teeth 340 are engaged with the first inclined teeth 500, the rotating column 310 is rotationally driven in a forward direction to synchronously rotate the sliding core 320, so that the second inclined teeth 340 are clamped with the first inclined teeth 500 to drive the rotating core 400 to rotate, thereby driving the valve core 110 of the valve body 100 to rotate, the rotating column 310 is rotationally driven in a reverse direction to synchronously rotate the sliding core 320, so that the second inclined teeth 340 and the first inclined teeth 500 are slid relative to each other, thereby keeping the rotating core 400 stationary.

[0035] It should be noted that the valve body 100 is a water valve structure on the market, specifically, the valve core 110 of the existing valve body 100 is driven by the handle, so that the user drives the valve core 110 to rotate by rotating the handle, thereby opening the valve body 100. The water regulating valve 10 provided by the application is used in cooperation with the valve body 100. Specifically, the handle of the existing valve body 100 is removed, and the valve core 110 of the valve body 100 is exposed outside the valve body 100. The sleeve 200 is sleeved and installed on the outer wall of the valve body 100, wherein the sleeve 200 can be fixedly installed on the valve body 100 by screw locking. The rotating core 400 is sleeved and fixed with the valve core 110 of the valve body 100. It should be noted that, since the valve core 110 of the existing valve body 100 is fixed with the handle, the outer wall of the valve core 110 is usually provided with anti-skid lines. In order to stably fix the rotating core 400 and the valve core 110 and avoid slipping between them, anti-skid lines are also provided on the inner wall of the rotating core 400. In this way, when the rotating core 400 rotates, the valve core 110 is also rotated, thereby closing or opening the valve body 100. Further, a plurality of first inclined teeth 500 are arranged on the end of the rotating core 400 away from the valve core 110. Further, the rotating column 310 can rotate relative to the sleeve 200, the sliding core 320 can slide along the axis of the rotating column 310, the elastic member 330 is in abutment with the sliding core 320 and the rotating column 310, for example, the elastic member 330 is a spiral spring. In this way, under the elastic pushing force of the elastic member 330, the second inclined teeth 340 on the end of the sliding core 320 are engaged with the first inclined teeth 500. It should be noted that the first inclined teeth 500 and the second inclined teeth 340 are identical in structure and opposite in direction, and are engaged with each other.

[0036] The rotating column 310 is a structure facing the user. The user applies an external force to the rotating column 310 to make it rotate in a positive direction or in a reverse direction. Here, the positive direction and the reverse direction are only used to describe that the rotating column 310 has two rotating directions. In one embodiment, the positive direction is clockwise rotation and the reverse direction is counterclockwise rotation. In another embodiment, the positive direction is counterclockwise rotation and the reverse direction is clockwise rotation.

[0037] For the convenience of description, the application takes the clockwise rotation as the forward rotation and the counterclockwise rotation as the reverse rotation as the embodiment for the illustration of the drawings. Thus, when the rotating column 310 rotates clockwise, the rotating column 310 drives the sliding core 320 to rotate, thereby driving the rotating core 400 to rotate, so that the valve core 110 of the valve body 100 can be stably driven to rotate clockwise. Correspondingly, the valve core 110 of the valve body 100 rotates clockwise to be closed. When the rotating column 310 rotates counterclockwise, the second inclined teeth 340 cannot drive the first inclined teeth 500 to rotate again because the second inclined teeth 340 cannot clamp the first inclined teeth 500 again. In the process of rotating the second inclined teeth 340, the sliding core 320 also compresses the elastic member 330, so that each second inclined tooth 340 and each first inclined tooth 500 are sequentially out of position. In this process, the rotating core 400 cannot continue to rotate counterclockwise, that is, the valve core 110 of the valve body 100 cannot continue to rotate counterclockwise. Therefore, the rotating column 310 rotates counterclockwise as invalid rotation, which means that the valve core 110 of the valve body 100 cannot be opened. Correspondingly, when it is necessary to ensure that the rotating core 400 can smoothly drive the valve core 110 to rotate counterclockwise to open the valve body 100, it is necessary to apply an axial pressure to the sliding core 320 to ensure that the second inclined teeth 340 stably engage with the first inclined teeth 500 under the action of an external force. When the rotating column 310 rotates counterclockwise, the second inclined teeth 340 can drive the first inclined teeth 500 to rotate counterclockwise.

[0038] The function principle of the water regulating valve 10 of the application is as follows: when the valve body 100 is in the open state, an external force is applied to the rotating column 310 to make it rotate clockwise, which can drive the valve core 110 to rotate clockwise to close the valve body 100. This action is not limited to adults or children. When the valve body 100 is in the closed state, only an external force is applied to the rotating column 310 to make it rotate counterclockwise. Because the second inclined teeth 340 cannot clamp the first inclined teeth 500, the valve core 110 stably remains stationary, that is, the valve body 100 cannot be opened. Only when an axial pressure is applied to the sliding core 320 to stably engage the second inclined teeth 340 with the first inclined teeth 500, and then an external force is applied to the rotating column 310 to make it rotate counterclockwise, can the valve core 110 rotate counterclockwise to open the valve body 100. Therefore, when a child unintentionally rotates the rotating column 310, the valve body 100 can only be closed in the closed / open state because the child does not apply pressure to the sliding core 320. When the valve body 100 is in the closed state, it cannot be opened, so the child can effectively prevent the child from performing the misoperation of opening. Moreover, the rotating core 400 can be connected with the valve core 110 of any brand of valve body 100 on the market, so the compatibility is better.

[0039] As Figure 2As shown, in an embodiment, the sleeve seat 200 is provided with a sleeve cavity 210 and a rotating cavity 220, the rotating core 400 is located in the rotating cavity 220 near one end of the first inclined tooth 500, and the rotating core 400 is located in the sleeve cavity 210 away from one end of the first inclined tooth 500. The inner side wall of the sleeve cavity 210 is used for sleeving on the outer side wall of the valve body 100, and the rotating column 310 is rotationally arranged in the rotating cavity 220.

[0040] It should be noted that in order to adapt to the valve body 100 installed on the market, the sleeve cavity 210 can be designed as a square, circular or other structure. Ensure that the sleeve cavity 210 can be sleeved and fixed on the outer side wall of the valve body 100. In this way, when the sleeve cavity 210 is sleeved on the valve body 100, the valve core 110 of the valve body 100 can be reliably connected with the rotating core 400.

[0041] As shown in Figure 2 and Figure 3 As shown, in an embodiment, the rotating core 400 includes a core column 410 and a rotating sleeve 420, the core column 410 is rotationally arranged in the sleeve seat 200, and the rotating sleeve 420 is detachably arranged on one end of the core column 410 located in the sleeve cavity 210. The rotating sleeve 420 is used for sleeving with the valve core 110 of the valve body 100, and each first inclined tooth 500 is arranged on one end of the core column 410 located in the rotating cavity 220.

[0042] It should be noted that since the valve core 110 of the valve body 100 on the market has different model diameters, in order to make different models of the valve body 100 can be installed and used, the rotating core 400 is arranged in a structure of the core column 410 and the rotating sleeve 420 combined installation. Specifically, the rotating sleeve 420 is used for sleeving and fixing with the valve core 110, so the rotating sleeve 420 can be replaced with a suitable size structure according to the diameter of the valve core 110. Among them, the rotating sleeve 420 is installed on the core column 410 through a screw, so that the rotating sleeve 420 and the core column 410 are detachably installed.

[0043] As shown in Figure 3 In order to avoid the rotating sleeve 420 and the core column 410 from rotating with each other, a clamping groove 411 is formed on one of the core column 410 and the rotating sleeve 420, and a clamping block 430 is arranged on the other one. The clamping block 430 is adaptively inserted into the clamping groove 411, so that the core column 410 stably drives the rotating sleeve 420 to rotate.

[0044] As shown in Figure 2 In an embodiment, an insertion slot 421 is formed on one end of the rotating sleeve 420 away from the core column 410, and the valve core 110 of the valve body 100 is used for inserting into the insertion slot 421.

[0045] It should be noted that the slot 421 and the valve core 110 are adaptively installed, for example, the outer side wall of the valve core 110 is usually provided with anti-skid lines, and correspondingly, the inner side wall of the slot 421 is also provided with corresponding anti-skid lines, so that the valve core 110 and the slot 421 are adaptively and stably inserted and fixed.

[0046] As shown in Figure 2 and Figure 3 In an embodiment, the first inclined tooth 500 has a straight surface 510 and an inclined surface 520, the straight surface 510 coincides with the axis of the rotating core 400, and the included angle between the inclined surface 520 and the straight surface 510 is greater than 1° and less than 90°.

[0047] It should be noted that the structure of the second inclined tooth 340 is the same as that of the first inclined tooth 500, so that when the second inclined tooth 340 rotates forward, the straight surface 510 of the second inclined tooth 340 will push the straight surface of the first inclined tooth 500, so that the second inclined tooth 340 can stably clamp the first inclined tooth 500 to rotate synchronously. When the second inclined tooth 340 rotates reversely, the inclined surface 520 of the second inclined tooth 340 pushes the inclined surface of the first inclined tooth 500, so that the second inclined tooth 340 will slide relative to the first inclined tooth 500, at this time the elastic member 330 is compressed, so that the second inclined tooth 340 will only idle, and will not drive the first inclined tooth 500 to rotate. In an embodiment, the included angle A between the inclined surface 520 and the straight surface 510 is 55°-70°. Further, in an embodiment, the included angle A between the inclined surface 520 and the straight surface 510 is 60°-70°. Further, in an embodiment, the included angle A between the inclined surface 520 and the straight surface 510 is 65°.

[0048] As shown in Figure 2 and Figure 4 In an embodiment, the outer side wall of the sliding core 320 is provided with a guide protrusion 350, the axis of the rotating column 310 is provided with a sliding hole 311, the inner side wall of the sliding hole 311 is provided with a guide groove 312, the sliding core 320 is arranged in the sliding hole 311, and the guide protrusion 350 is slidably arranged in the guide groove 312.

[0049] It should be noted that in order to ensure that the sliding core 320 only slides along the axial direction of the rotating column 310 and does not rotate relative to the rotating column 310, the guide protrusion 350 is arranged on the sliding core 320, and correspondingly, the guide groove 312 is arranged on the rotating column 310, and the guide protrusion 350 is adaptively and slidably arranged in the guide groove 312. In an embodiment, the guide protrusion 350 is provided with two, and the two guide protrusions 350 are located on opposite sides of the sliding core 320. Correspondingly, the guide groove 312 is provided with two, and the two guide protrusions 350 are respectively slidably arranged in the two guide grooves 312.

[0050] As shown in Figure 2As shown, in one embodiment, the top of the slide core 320 is located inside the slide hole 311. It should be noted that the slide core 320 is located inside the slide hole 311, which further improves the safety of the slide core 320 and prevents children from accidentally pressing the slide core 320.

[0051] like Figure 1 and Figure 2 As shown, in one embodiment, the screwing assembly 300 further includes a top post 360, which is used to insert into the sliding hole 311 to press against the sliding core 320.

[0052] It should be noted that the top post 360 is inserted into the outer wall of the rotating post 310. When needed, the top post 360 is removed and inserted into the sliding hole 311 to press against the sliding core 320.

[0053] like Figure 1 and Figure 2 As shown, in one embodiment, a handle 370 is provided on the outer side wall of the rotating column 310. The handle 370 extends outward along the radial direction of the rotating column 310, and the top column 360 is detachably provided on the end of the handle 370 away from the rotating column 310.

[0054] This allows the user to apply external force to the rotating column 310 via the handle 370. Furthermore, in one embodiment, the top column 360 is provided with external threads, and the tail end of the handle 370 is provided with a threaded hole. Therefore, the top column 360 can be screwed tightly onto the tail end of the handle 370. When it is necessary to open the valve body 100, the top column 360 is removed from the handle 370, the top column 360 is pressed against the sliding core 320, and the rotating column 310 is rotated via the handle 370.

[0055] Thus, the water regulating valve 10 of this application can be used in conjunction with the valve body 100 available on the market, with good compatibility and can effectively prevent children from accidentally opening it, ensuring high safety. At the same time, it does not affect normal use and can be safely installed in bathtubs that need to release high-temperature hot water.
