When using the water outlet, such as when using a hand-held shower, if the shower is rotated, the connector and the water supply pipe are often driven to rotate together, making the water supply pipe easy to entangle. In addition, the adjustment of the water flow size of the water outlet and the opening and closing operation of the water flow are usually controlled at the water inlet end of the water supply pipe, which is inconvenient for users during use. An existing technical solution is to adjust the water flow in the water supply pipe. For example, patent CN211779469U provides a hose structure with adjustable water outlet temperature. A through cold water channel and a hot water channel are set in the pipe body, and a ring-shaped hot water channel surrounds the cold water channel, or a ring-shaped cold water channel surrounds the hot water channel. The cold and hot water double water channels are discharged, and a temperature regulating mechanism for adjusting the flow of cold and hot water is set to achieve hot water flow regulation, thereby adjusting the temperature of the outflowing water by controlling the hot water flow.

[0011] Based on Technical Solution Five, Technical Solution Seven is also provided, which further includes a limit block and a first limit sleeve; the inner wall of the sleeve is provided with a first step surface facing the same water outlet direction as the water outlet hole and a second step surface facing the opposite water outlet direction of the water outlet hole; the outer wall of the valve body is provided with a support surface facing the same water outlet direction as the water outlet hole; the limit block abuts the first step surface and is sealingly mounted outside the valve body; the first limit sleeve abuts the second step surface and the support surface is mounted outside the valve body.

[0012] Technical Solution 8, a water outlet device, comprising a water outlet part, a water supply pipe and a connecting part as described in any one of Technical Solutions 4 to 7, wherein the end of the connecting sleeve close to the water outlet hole is configured to be suitable for fixed connection with the water outlet part, and the end of the sealing part close to the water outlet is configured to be suitable for fixed connection with the water supply pipe.

[0013] Based on technical solution eight, technical solution nine is also provided. In technical solution nine, the water supply pipe is a hose, and the end of the connecting sleeve close to the water outlet is threadedly connected to the water outlet piece; the end of the sealing piece close to the water outlet is suitable for being inserted into the water supply pipe.

[0014] Based on Technical Solution Nine, Technical Solution Ten is also provided. Technical Solution Ten also includes a second limit sleeve, and an inner wall of the end of the connecting sleeve away from the water outlet is provided with a limit surface, and the second limit sleeve is arranged outside the water supply pipe and fixed relative to the water supply pipe along the axial direction of the connecting cavity, and the end of the second limit sleeve away from the water outlet is configured to be suitable for abutting against the limit surface to prevent the sealing member from being separated from the threaded cooperation with the connecting cavity.

[0015] Based on technical solutions eight to ten, there is also a technical solution eleven. In technical solution eleven, the water outlet is a hand-held shower.

[0016] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the first technical solution, when the plugging piece rotates and moves axially relative to the valve body, the plugging part blocks the water outlet or opens the water outlet. Since the plugging piece and the valve body are threadedly matched, the plugging piece can stay at several positions relative to the valve body along the axial direction of the connecting cavity. For example, when the plugging piece opens the water outlet, the gap between the plugging piece and the water outlet can be large or small, thereby adjusting the water flow rate. By adopting this technical solution, a new valve core for switching water on and off and adjusting the water flow size can be provided, and only two components are required to realize switching water on and off and adjusting the water flow size, and the structure is simple and practical. This valve core can be used in a water outlet device to realize switching water on and off and adjusting the water flow size, which is convenient for users to operate and low in cost.

[0018] 2. In the second technical solution, the sealing member and the cavity wall of the connecting cavity between the water outlet and the internal thread are sealed to form a water passage cavity connected to the water outlet, thereby preventing water from entering the external thread of the sealing member and the internal thread of the connecting cavity, thereby preventing the external thread and the internal thread from being corroded and damaged.

[0019] 3. In the technical solution three, a water outlet is provided at the end of the water channel away from the water outlet, so as to facilitate the connection of the plugging part with the water pipe and realize axial water inlet, and the structure is simple and practical.

[0020] 4. In technical solution four, the present invention provides a connecting piece, which includes the above-mentioned valve body and connecting sleeve, so that the connecting piece can turn water on and off and adjust the water flow, and the structure is simple and practical; using this technical solution, only when the elastic buckle is inserted into the slot, the connecting sleeve and the valve body are relatively fixed, and the blocking piece can be rotated and axially moved relative to the valve body to open and close the water outlet; when the elastic buckle is not inserted into the slot, rotating the blocking piece or the valve body will cause the blocking piece and the valve body to rotate synchronously, thereby allowing the connecting sleeve to rotate freely relative to the valve core, and in order to insert the elastic buckle into the slot, the elastic buckle needs to be pressed. Therefore, when the present technical solution is in use, the water outlet hole can be opened and closed and the water flow rate can be adjusted only by continuously pressing the elastic buckle so that the elastic buckle is inserted into the slot of the valve body and rotating the sealing piece or the connecting sleeve. A single pressing operation or a rotating operation cannot open and close the water outlet hole and adjust the water flow rate, thereby avoiding misoperation. Moreover, the connecting sleeve can rotate relative to the valve core under a single rotating operation. Such a connecting piece can be applied to a water outlet device, which can realize the operation of turning water on and off and adjusting the water flow rate on the connecting piece, and can also enable the connecting piece to rotate relative to the valve body, thereby creating conditions for preventing the water supply pipe from being entangled.

[0021] 5. In the fifth technical solution, the through hole is formed in the sleeve body, and the elastic buckle is formed in the pressing sleeve. The structure is simple and practical, and is easy to produce and process.

[0022] 6. In technical solution six, a first annular groove is provided on the outer wall of the sleeve body, the pressing sleeve is clamped with the first annular groove, and the elastic buckle is always inserted in the through hole. The connection between the pressing sleeve and the sleeve body is more stable, and it is convenient to make the elastic buckle face the through hole during installation.

[0023] 7. In technical solution seven, a limit block and a first limit sleeve are provided. The limit block abuts the first step surface and is sealingly sleeved outside the valve body. The first limit sleeve abuts the second step surface and the support surface. The cooperation between the limit block and the first step surface limits the movement of the valve body in the direction opposite to the water outlet direction of the water outlet. The cooperation between the first limit sleeve and the second step surface and the support surface limits the movement of the valve body in the same direction as the water outlet direction of the water outlet. This achieves that the valve body and the sleeve are relatively fixed along the axial direction of the connecting cavity when in use. This not only has a simple structure, but is also easy to produce and process.

[0024] 8. In technical solution eight, the present invention provides a water outlet device, which includes the above-mentioned connection structure, water outlet parts and water supply pipe. The structure is simple and practical. When it is necessary to adjust the water outlet flow or turn on and off the water, the elastic buckle is pressed and the elastic buckle is inserted into the card slot of the valve body, and the connecting sleeve is relatively fixed to the valve body, and the end of the connecting sleeve close to the water outlet hole is fixed to the water outlet part, and the water outlet part is also relatively fixed to the connecting sleeve, so that one of the water outlet part and the water supply pipe is fixed, and the other is rotated, and the plug of the blocking part is rotated relative to the valve body and axially moved to open and close the water outlet hole, and the water outlet hole is opened and closed. The user can turn water on and off and adjust the water flow at a position close to the water outlet, which is more convenient to use, and a single pressing operation or rotating operation cannot open or close the water outlet and adjust the water flow, thereby avoiding misoperation; and during use, when only the water outlet needs to be rotated, the elastic buckle is not pressed, the water outlet and the connecting sleeve rotate synchronously to form a unit, and the valve core and the water supply pipe are fixed to form another unit, and the two units rotate relative to each other, avoiding entanglement of the water supply pipe; in addition, the water outlet device of the present technical solution has a simple and practical structure and is easy to produce and process.

[0025] 9. In technical solution nine, the water supply pipe is a hose, and the end of the connecting sleeve close to the water outlet is threadedly connected to the water outlet part. The structure is simple and practical, and is easy to produce, process and disassemble; the end of the sealing part close to the water outlet is suitable for being inserted into the water supply pipe, which is easy to disassemble.

[0026] 10. In technical solution 10, a second limiting sleeve is provided, which can prevent the blocking member from being separated from the threaded engagement with the connecting cavity, and the structure is more stable.

[0027] 11. In technical solution XI, the water outlet is a hand-held shower. During showering, if you only need to adjust the position of the hand-held shower, there is no need to press the elastic buckle, thereby preventing the water supply hose from being entangled. If you need to adjust the water flow rate and turn the water on and off, continue to press the elastic buckle and rotate the connecting sleeve until the elastic buckle is inserted into the slot, then hold the connecting sleeve or the hand-held shower and rotate the water supply pipe.

[0050] See also Figure 1-2 , Figure 1-2 A valve core 100 is shown, and the valve core 100 includes a valve body 110 and a blocking member 120 .

[0051] like Figure 1-2 and Figure 6-8 As shown, the valve body 110 is provided with a connecting cavity 114 and a water outlet 1131 located at the end of the connecting cavity 114, and the cavity wall of the connecting cavity 114 is provided with an internal thread. In this embodiment, the valve body 110 includes a first section 111, a second section 112 and a third section 113 connected in sequence, the outer diameter of the first section 111 of the valve body 110 is greater than the outer diameter of the second section 112 of the valve body 110, the outer diameter of the second section 112 of the valve body 110 is greater than the outer diameter of the third section 113 of the valve body 110, and a plane between the first section 111 and the second section 112 that is perpendicular to the axis of the connecting cavity 114 forms a support surface 1111.

[0052] The water outlet hole 1131 is formed at the end of the third section 113 of the valve body 110, the connecting cavity 114 is formed in the first section 111 of the valve body 110, the second section 112 of the valve body 110 and the third section 113 of the valve body 110, and the internal thread is formed on the inner wall of the first section 111 of the valve body 110, wherein the wall of the first section 111 of the valve body 110 is also provided with a groove 1112 that passes through the inside and outside of the valve body 110; the outer wall of the third section 113 of the valve body 110 is also provided with a second annular groove 1132 near the water outlet hole 1131.

[0053] In this embodiment, the inner wall of the third section 113 of the valve body 110 is provided with a first annular protrusion 1133 at the water outlet 1131, and the first annular protrusion 1133 is provided with a sealing surface 11331 and a guide surface 11332 connected to each other. The sealing surface 11331 is parallel to the axial direction of the connecting cavity 114, and the guide surface 11332 is inclined relative to the axial direction of the connecting cavity 114 and faces the connecting cavity 114, and the guide surface 11332 is conical.

[0054] The plugging member 120 has a plugging portion 121 at one end and an inserting portion 122 at the other end. The outer wall of the middle portion of the plugging member 120 has an external thread. The sealing sleeve on the outer wall of the plugging member 120 between the plugging portion 121 and the external thread is provided with a first sealing ring 123. Similarly, the outer periphery of the plugging portion 121 is also sleeved with a second sealing ring 1211. The plugging member 120 has a water passage 124. The water passage 124 has a water opening 1241 at the end away from the plugging portion 121, that is, the water opening 1241 is provided at the end of the inserting portion 122. The water passage 124 has a water opening 1242 on the outer wall between the plugging portion 121 and the first sealing ring 123 of the plugging member 120. In this embodiment, the outer diameter of the plugging member 120 at the water opening 1242 is smaller than the outer diameter of the plugging member 120 at the first sealing ring 123.

[0055] It should be understood that the first sealing ring 123 and the second sealing ring 1211 are both installed in the annular groove on the outer wall of the blocking member 120 during specific installation, so as to be fixed axially relative to the blocking member 120 .

[0056] The plugging member 120 is inserted into the connecting cavity 114, and the external thread of the plugging member 120 cooperates with the internal thread of the first section 111 of the valve body 110 so that the plugging member 120 is screwed to the valve body 110. The external wall of the plugging member 120 and the cavity wall of the connecting cavity 114 located between the water outlet 1131 and the internal thread are sealed and cooperated to form a water passage cavity, thereby preventing the external thread of the plugging member 120 and the internal thread of the connecting cavity 114 from entering water, thereby preventing the external thread and the internal thread from being corroded and damaged. Specifically, the first sealing ring 123 of the plugging member 120 is sealed and cooperated with the inner wall of the second section 112 of the valve body 110, and the external wall of the plugging member 120 located between the first sealing ring 123 and the end face of the plugging portion 121 has a gap with the inner wall of the second section 112 and the third section 113 of the valve body 110 to form a water passage cavity, and the water passage 124 is always connected to the water passage cavity through the water opening 1242.

[0057] When in use, the blocking member 120 rotates relative to the valve body 110 and then moves axially, and the blocking portion 121 is inserted into or withdrawn from the water outlet 1131. When the blocking portion 121 is inserted into the water outlet 1131, the second sealing ring 1211 on the blocking portion 121 and the sealing surface 11331 of the first annular protrusion 1133 seal and press to close the water outlet 1131. When the blocking portion 121 withdraws from the water outlet 1131, the water passage 124 is connected with the water passage cavity and the water outlet 1131 through the water opening 1242. When it is necessary to increase the water flow rate, the blocking member 120 is rotated upward, such as Figure 7 As shown, the gap between the blocking portion 121 and the guide surface 11332 of the first annular protrusion 1133 is reduced. The setting of the guide surface 11332 facilitates the blocking portion 121 to be inserted into the water outlet 1131.

[0058] It can be seen from the above technical scheme that when the blocking piece 120 rotates and moves axially relative to the valve body 110, the blocking portion 121 blocks the water outlet 1131 or opens the water outlet 1131. Since the blocking piece 120 and the valve body 110 are threadedly matched, the blocking piece 120 can stay at several positions relative to the valve body 110 along the axial direction of the connecting cavity 114. For example, when the blocking piece 121 opens the water outlet 1131, the gap between the blocking piece 121 and the guide surface 11332 can be large or small, thereby adjusting the water flow rate; the water channel 124 is provided with a water outlet 1241 at the end away from the water outlet 1131, which is convenient for connecting the blocking piece 120 with the water pipe to realize axial water inlet, and the structure is simple and practical. By adopting this technical solution, a new valve core 100 for turning water on and off and adjusting the water flow size can be provided, and only two components are required to realize turning water on and off and adjusting the water flow size, and the structure is simple and practical; this valve core 100 can be used in a water outlet device to realize turning water on and off and adjusting the water flow size, which is convenient for users to operate and low cost.

[0059] like Figure 3-4 As shown, the present invention also provides a connecting piece, which includes the valve core 100, the connecting sleeve 200, the limiting block 300 and the first limiting sleeve 400 in the above embodiment.

[0060] The connecting sleeve 200 includes a sleeve body 210 and a pressing sleeve 220 .

[0061] like Figure 3-4 and Figure 6-8As shown, the sleeve 210 has openings at both ends, and an inner wall at one end of the sleeve 210 is formed with an internal thread. The inner wall of the sleeve 210 is provided with a second annular protrusion 211 and a third annular protrusion 212 at intervals along the axial direction. In this embodiment, the third annular protrusion 212 is formed on the inner wall at the other end of the sleeve 210, and the second annular protrusion 211 is close to the internal thread of the sleeve 210. The end surface of the second annular protrusion 211 facing the side where the internal thread is located forms a first step surface 2111, the end surface of the second annular protrusion 211 facing the side where the third annular protrusion 212 is located forms a second step surface 2112, and the end surface of the third annular protrusion 212 facing the side where the internal thread is located forms a limiting surface 2121. A first annular groove 213 is provided on the outer wall at the other end of the sleeve 210, and a through hole 214 is provided on the wall of the sleeve 210. In this embodiment, the through hole 214 is partially located on the wall of the first annular groove 213 and partially located outside the first annular groove 213.

[0062] The pressing sleeve 220 is open at both ends, and an elastic buckle 221 is provided on the outer wall thereof extending in a direction parallel to the axis of the pressing sleeve 220. The elastic buckle 221 is parallel to the axis of the pressing sleeve 220 when not under force, and rotates inwards when under force. In this embodiment, the elastic buckle 221 is adapted to the through hole 214, the pressing sleeve 220 is sleeved on the first annular groove 213, and the elastic buckle 221 is always inserted in the through hole 214 so that the pressing sleeve 220 is engaged with the first annular groove 213. The structural design of the connecting sleeve 200 is simple and practical, easy to produce and process, and makes the connection between the pressing sleeve 220 and the sleeve body 210 more stable, and it is convenient to make the elastic buckle 221 face the through hole 214 during installation.

[0063] The limit block 300 includes a steering ring 310, a sealing gasket 320 and a retaining spring 330. The outer wall of the steering ring 310 is provided with a fourth annular protrusion 311 and a fifth annular protrusion 312 extending radially in the axial direction, wherein the extension distance of the fifth annular protrusion 312 is greater than the extension distance of the fourth annular protrusion 311. The inner wall of the steering ring 310 is provided with a third annular groove 313, and a third sealing ring 3131 is sleeved in the third annular groove 313. The inner wall of the sealing gasket 320 is provided with a fourth annular groove 321, wherein the fourth annular groove 321 is clamped with the fourth annular protrusion 311, so that the sealing gasket 320 is clamped with the steering ring 310 in the axial direction, and the retaining spring 330 is placed on the outer groove wall of the third annular groove 313.

[0064] In this embodiment, the first limit sleeve 400 is sleeved on the outer wall of the second section 112 of the valve body 110 and abuts the support surface 1111. The connecting sleeve 200 is sleeved on the outside of the valve body 110 and is relatively fixed to the valve body 110 along the axial direction of the connecting cavity 114, which is mainly achieved by the cooperation between the second annular protrusion 211 and the limit block 300 and the first limit sleeve 400. The limit block 300 abuts the first step surface 2111 and is sealingly sleeved on the outside of the valve body 110. The first limit sleeve 400 abuts the second step surface 2112 and the support surface 1111 and is sleeved on the outside of the valve body 110. When the through hole 214 is opposite to the slot 1112, the elastic buckle 221 is also suitable for being inserted into the slot 1112. Specifically, the turning ring 310 is sealingly sleeved on the outer wall of the valve body 110 near one end of the water outlet 1131, wherein the fourth annular protrusion 311 is closer to the water outlet 1131 than the fifth annular protrusion 312, the fifth annular protrusion 312 abuts against the first step surface 2111, the retaining ring 330 is inserted into the second annular groove 1132 of the valve body 110 and abuts against the outer groove wall of the third annular groove 313, and the third sealing ring 3131 is sealingly pressed against the outer wall of the third section 113 of the valve body 110. The steering ring 310 is restricted by the retaining spring 330 and cannot move upward relative to the valve body 110. At the same time, the steering ring 310 is restricted by the first step surface 2111 and cannot move downward relative to the connecting sleeve 200. Therefore, the steering ring 310 is fixed relative to the sleeve body 210 along the axial direction of the connecting chamber 114, and the valve body 110 is restricted by the retaining spring 330 and cannot move downward relative to the limit block 300; at the same time, the first limit sleeve 400 is restricted by the second step surface 2112 and cannot move upward relative to the connecting sleeve 200, so that the valve body 110 cannot move upward relative to the connecting sleeve 200, thereby achieving the valve body 110 and the sleeve body 210 being relatively fixed along the axial direction of the connecting chamber 114 when in use.

[0065] During installation, the limit block 300 is sealedly sleeved on the outside of the valve body 110 as a whole. Specifically, the steering ring 310 is first sealedly sleeved on the outside of the valve body 110 and then moved downward for a certain distance. Then, the retaining spring 330 is inserted into the second annular groove 1132 of the valve body 110. Then, the steering ring 310 is moved upward until the outer groove wall of the third annular groove 313 of the steering ring 310 abuts against the retaining spring 330. Then, the fourth annular groove 321 of the sealing gasket 320 is clamped with the fourth annular protrusion 311 of the steering ring 310, so that the sealing gasket 320 and the steering ring 310 are clamped axially. The first limiting sleeve 400 is sleeved on the outer wall of the second section 112 of the valve body 110 and abuts the supporting surface 1111, so that the pressing sleeve 220 is clamped with the first annular groove 213 of the sleeve body 210 and the elastic buckle 221 is always inserted in the through hole 214; then the sleeve body 210 is sleeved outside the valve body 110, and the fifth annular protrusion 312 of the turning ring 310 abuts against the first step surface 2111 of the second annular protrusion 211 of the sleeve body 210 to limit the downward movement of the valve body 110, and the first limiting sleeve 400 abuts against the second step surface 2112 to limit the upward movement of the valve body 110.

[0066] It can be seen from the above technical scheme that the connecting piece includes the above-mentioned valve body 110 and the connecting sleeve 200, so that the connecting piece can turn water on and off and adjust the water flow, and the structure is simple and practical; with the present technical scheme, only when the elastic buckle 221 is inserted into the slot 1112, the connecting sleeve 200 and the valve body 110 are relatively fixed, so that the blocking piece 120 can be rotated and axially moved relative to the valve body 110 to open and close the water outlet 1131; when the elastic buckle 221 is not inserted into the slot 1112, rotating the blocking piece 120 or the valve body 110 will cause the blocking piece 120 and the valve body 110 to rotate synchronously, thereby allowing the connecting sleeve 200 to rotate freely relative to the valve core 100, and in order to insert the elastic buckle 221 into the slot 1112, it is necessary to keep the elastic buckle 221 pressed. Therefore, when the present technical solution is in use, the water outlet hole 1131 can be opened and closed and the water flow rate can be adjusted only by continuously pressing the elastic buckle 221 so that the elastic buckle 221 is inserted into the slot 1112 of the valve body 110 and rotating the blocking member 120 or the connecting sleeve 200. A single pressing operation or a rotating operation cannot open and close the water outlet hole 1131 and adjust the water flow rate, thereby avoiding misoperation. In addition, the connecting sleeve 200 can rotate relative to the valve core 100 under a single rotating operation. Such a connecting piece can be applied to a water outlet device, which can realize the operation of turning water on and off and adjusting the water flow rate on the connecting piece, and can also enable the connecting piece to rotate relative to the valve body 110, thereby creating conditions for preventing the water supply pipe 600 from being entangled.

[0067] like Figure 5 , 9 -10, the present invention also provides a water outlet device, including a water outlet member 500, a water supply pipe 600, a connecting member in the above embodiment and a second limiting sleeve 700.

[0068] The water outlet 500 is a hand-held shower head in this embodiment, and an outer wall of the water inlet end of the hand-held shower head is provided with an external thread.

[0069] The water supply pipe 600 is a hose.

[0070] like Figure 6-10 As shown, in actual application, the second limiting sleeve 700 includes an iron hoop 710 and a limiting ring 720 . The outer wall of the iron hoop 710 is provided with a fifth ring groove 711 . The limiting ring 720 is sleeved in the fifth ring groove 711 and partially extends out of the fifth ring groove 711 .

[0071] The second limiting sleeve 700 is sleeved outside the water supply pipe 600 and fixed relative to the water supply pipe 600 along the axial direction of the connecting cavity 114. Specifically, after the plugging member 120 is inserted into the water supply pipe 600, the iron hoop 710 tightens the water supply pipe 600, and the limiting ring 720 is sleeved in the fifth annular groove 711 of the iron hoop 710 and partially extends out of the fifth annular groove 711. After the connecting sleeve 200 is sleeved on the valve body 110, the first limiting sleeve 400 and the second limiting sleeve 700 are located between the second annular protrusion 211 and the third annular protrusion 212. One end of the connecting sleeve 200 close to the water outlet hole 1131 is threadedly connected to the water outlet member 500, and the water inlet end of the water outlet member 500 presses against the sealing gasket 320 of the limit block 300. When the water outlet member 500 rotates, it is resisted by the sealing gasket 320 and cannot move axially relative to the connecting sleeve 200. Therefore, the water outlet member 500 and the connecting sleeve 200 are relatively fixed.

[0072] The inserting portion 122 of the blocking member 120 is inserted into the water supply pipe 600 .

[0073] The installation process is as follows:

[0074] First, insert the insertion portion 122 of the blocking member 120 into the water supply pipe 600, then fix the hose with the iron hoop 710 of the second limiting sleeve 700, and sleeve the limiting ring 720 on the fifth ring groove 711 of the iron hoop 710;

[0075] Then, the limit block 300 is sealed and sleeved outside the valve body 110 as described above;

[0076] The first limiting sleeve 400 is disposed on the outer wall of the second section 112 of the valve body 110 and abuts against the supporting surface 1111;

[0077] The pressing sleeve 220 is engaged with the first annular groove 213 of the sleeve body 210, and the elastic buckle 221 of the pressing sleeve 220 is inserted into the through hole 214 of the sleeve body 210;

[0078] Insert the assembled connecting sleeve 200 into the blocking piece 120, screw the valve body 110 and the blocking piece 120 together, and then pull the connecting sleeve 200 upward until the first limiting sleeve 400 and the second limiting sleeve 700 are located between the second annular protrusion 211 and the third annular protrusion 212;

[0079] Finally, the water inlet end of the hand-held shower is screwed to one end of the connecting sleeve 200 close to the water outlet hole 1131 , and the water inlet end of the hand-held shower is in contact with the sealing gasket 320 .

[0080] The usage process is as follows:

[0081] When it is necessary to adjust the water flow rate or turn the water on or off, hold the water supply pipe 600, continue to press the elastic buckle 221 and rotate the connecting sleeve 200 until the elastic buckle 221 is inserted into the card slot 1112, the connecting sleeve 200 is relatively fixed to the valve body 110, the water outlet member 500 is relatively fixed to the connecting sleeve 200, and the water outlet member 500 is rotated. The blocking portion 121 of the blocking member 120 is rotated and axially moved relative to the valve body 110 to open and close the water outlet hole 1131. When it is necessary to increase the water flow rate, the water outlet member 500 is rotated downward. Figure 7 As shown, the gap between the blocking portion 121 and the guide surface 11332 is reduced.

[0082] When adjusting the position of the hand-held shower, just rotate the hand-held shower without pressing the elastic buckle 221. The water outlet 500 and the connecting sleeve 200 rotate synchronously to form a unit, and the valve core 100 and the water supply pipe 600 are fixedly connected to form another unit. The two units rotate relative to each other to avoid the water supply pipe 600 from being entangled.

[0083] It can be seen from the above technical scheme that a single pressing operation or rotating operation cannot open or close the water outlet 1131 and adjust the water flow rate, thereby avoiding misoperation; the water outlet device of the present technical scheme has a simple and practical structure and is easy to produce and process; the water supply pipe 600 is a hose, and the end of the connecting sleeve 200 close to the water outlet 1131 is threadedly connected to the water outlet part 500, which has a simple and practical structure and is easy to produce, process and disassemble; the insertion portion 122 of the sealing member 120 is suitable for being inserted into the water supply pipe 600, which is easy to disassemble; the setting of the second limiting sleeve 700 can prevent the sealing member 120 from being separated from the threaded fit with the connecting cavity 114, and the structure is more stable.

[0084] The description of the above specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Through the enlightenment of the present invention or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent substitutions or other improvements to the embodiments of the present invention or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the present invention.
