[0018] From the above description of the present application, the present application has the following beneficial effects relative to the prior art:

[0019] 1. The transmission member is arranged between the push button and the rotating member. When the push button slides, the driving force of the push button in the sliding direction is converted into a force for driving the rotating member to rotate along the first axis through the transmission member, so that the rotating member can be driven to rotate by the sliding of the push button to change the communication state of the water passage and the water outlet channel. In the process of rotation, the pushing force is not affected by the water pressure, and the initial pushing force can be maintained at all times.

[0020] 2. The push button is fixedly connected with the transmission member. When the push button slides, the transmission member is driven to slide together. The transmission member is in screw cooperation with the rotating member, and the rotating member is axially limited in the accommodating cavity and cannot slide along the first direction. When the transmission member slides, only the rotating member can be driven to rotate to change the communication state of the water passage and the water outlet channel. Through the screw cooperation between the push button and the rotating member, the push button drives the rotating member to rotate by sliding, and in the process of rotation, the pushing force is not affected by the water pressure, and the initial pushing force can be maintained at all times.

[0021] 3. The first protrusion and the groove extending in a spiral shape are arranged on the outer wall of the rotating member, and the screw part matched with the side wall inclined surface of the first protrusion or the groove is arranged on the transmission member, so as to realize the screw cooperation between the rotating member and the transmission member with a simple structure.

[0022] 4. The water outlet end of the water passage is provided with the first water passage and the second water passage arranged on the rotating member in the circumferential direction. Since the first water passage and the second water passage are connected and communicated with each other, and the opening size of the second water passage gradually decreases away from the first water passage, the rotating member is arranged in this way, so that the size of the water flow is a gradual process during rotation adjustment.

[0023] 5. The second water passage is arranged on both sides of the first water passage, so that the rotating member can realize the gradual change effect of the water flow whether it rotates clockwise or counterclockwise.

[0024] 6. The first seat body and the second seat body are detachably connected and surrounded by each other to form the accommodating cavity and the sliding hole, so as to facilitate the installation of the rotating member and the push button.

[0025] 7. The two ends of the rotating member abut against the cavity walls at both ends of the accommodating cavity, so as to realize the axial limiting arrangement of the rotating member in the accommodating cavity with a simple structure.

[0026] 8. The second protrusion and the third protrusion are arranged at two ends of the rotating member body respectively, and the second protrusion and the third protrusion abut against the cavity wall at two ends of the accommodating cavity respectively, so that the rotating member is arranged in the accommodating cavity in the axial limiting mode. The second protrusion and the third protrusion are arranged, so that the contact area between the rotating member and the cavity wall of the accommodating cavity is small, and the area of abrasion caused by the friction force when the rotating member rotates is also small. The rotating member body is not easy to be abraded, and the normal use of the valve is not affected.

[0027] 9. The first sealing member and the second sealing member are arranged, so that when the rotating member is arranged in the accommodating cavity, the first sealing member and the second sealing member abut against the cavity wall of the accommodating cavity, and the accommodating cavity is divided to form the water outlet cavity, the rotating cavity and the water inlet cavity. The water inlet end of the water passing channel is located in the water inlet cavity, the water outlet end of the water passing channel is located in the water outlet cavity, and the sliding hole is communicated with the rotating cavity. In this way, the rotating cavity is in a sealed state with the water outlet cavity and the water inlet cavity, so that the rotating cavity is completely isolated from water, and the push button is not affected by the water pressure when sliding.

[0028] 10. The water outlet cavity comprises the first groove and the first hole, and the width of the first groove gradually decreases along the direction away from the first hole in the direction perpendicular to the first direction. The part of the rotating member body located in the water outlet cavity is matched with the water outlet cavity. In this way, the gap between the water outlet cavity and the end surface of the rotating member is as small as possible, and if the water flowing out of the water outlet end of the water passing channel leaks into the water outlet cavity, the water outlet cavity will not accumulate too much water.

[0029] 11. The water outlet device comprises the valve described above, and has all the beneficial effects of the valve. BRIEF DESCRIPTION OF DRAWINGS

[0065] Example 1:

[0066] like Figures 1 to 12 As shown, the valve includes a valve body 100, a rotating component 3, a push button 4, a transmission component 10, a first sealing component 5, a second sealing component 6, and a fixing component.

[0067] like Figures 1 to 4 As shown, the valve body 100 has a receiving cavity 1001 extending along a first direction D1, a sliding hole 1002 communicating with the receiving cavity 1001, a water inlet channel 12, and at least one water outlet channel. In this embodiment, the first direction D1 is as follows: Figure 3 As shown. In actual use, the valve body 100 includes a first seat 1 and a second seat 2. The first seat 1 and the second seat 2 are detachably connected and enclose each other to form a receiving cavity 1001 and a sliding hole 1002, the sliding hole 1002 being located on the side wall of the receiving cavity 1001. A water inlet channel 12 is provided on the first seat 1, and a water outlet channel is provided on the second seat 2; this arrangement facilitates the installation of the rotating component 3 and the push button 4. In this embodiment, the water outlet channel includes a first water outlet channel 21.

[0068] like Figure 5 As shown, the first base 1 includes a first body extending along a first direction D1, a first cavity 11 opening at one end of the first body, and a water inlet channel 12 communicating with the first cavity 11 penetrating the end face of the first body opposite to the opening of the first cavity 11. Figure 3 As shown, the inner wall of the first cavity 11 is provided with an annular first limiting surface 13 and a second limiting surface 14, and both the first limiting surface 13 and the second limiting surface 14 face the opening of the first cavity 11, and the second limiting surface 14 is closer to the water inlet channel 12 than the first limiting surface 13.

[0069] like Figure 5As shown, the side wall of the first cavity 11 is provided with a first notch 15 in communication with the first cavity 11, the first notch 15 extends along the first direction D1 and one end thereof penetrates the end face of the open end of the first cavity 11. The side wall of the first cavity 11 is also symmetrically provided with two first clamping grooves 16. The side wall of the one end of the water inlet channel 12 of the first body is provided with a first protruding rib 17 extending along the first direction D1.

[0070] As shown in Figure 6 and Figure 7 , the second seat body 2 includes a second body extending along the first direction D1, and the second body is internally provided with a first water outlet channel 21 extending along the first direction D1 and a second cavity 22 opening at one end thereof. The water inlet end of the first water outlet channel 21 opens at the side wall of the second cavity 22, and the water outlet end thereof opens at one end of the second body away from the opening of the second cavity 22. As shown in Figure 4 , the inner wall of the second cavity 22 is provided with an annular third limiting surface 23 and a fourth limiting surface 24, and both the third limiting surface 23 and the fourth limiting surface 24 are directed towards the opening of the second cavity 22. The third limiting surface 23 is closer to the opening of the second cavity 22 than the fourth limiting surface 24.

[0071] As shown in Figure 6 and Figure 7 , the end face of the opening end of the second cavity 22 is provided with a first clamping jaw 25 extending along the first direction D1 and a first protruding column 26 with a circular arc cross section. Among them, the number of first clamping jaws 25 is two, and each is matched with a first clamping groove 16. The first protruding column 26 is provided with two, and the two first protruding columns 26 are respectively located on both sides of the first clamping jaw 25. One of the first protruding columns 26 is provided with a second notch 27 extending along the first direction D1. The second notch 27 penetrates the end face of the free end of the first protruding column 26 and extends to the side wall of the second body in communication with the second cavity 22.

[0072] In this embodiment, as shown in Figures 2 to 4 , the opening of the first cavity 11 of the first seat body 1 and the opening of the second cavity 22 of the second seat body 2 are opposite, and they are detachably connected through the clamping and matching of the first clamping jaw 25 and the first clamping groove 16, and the cavity wall of the first cavity 11, the cavity wall of the second cavity 22 and the first protruding column 26 together form a containing cavity 1001. When the first seat body 1 and the second seat body 2 are clamped together, the first protruding column 26 of the second seat body 2 provided with the second notch 27 is located above the first notch 15 of the first seat body 1, and the end face of the first protruding column 26 abuts against the bottom wall of the first cavity 11, so that the inner wall of the second notch 27 and the bottom wall of the first cavity 11 form a sliding hole 1002 in communication with the containing cavity 1001. The first protruding column 26 without the second notch 27 is inserted into the first cavity 11.

[0073] As shown in Figure 2 and Figure 3As shown, the rotating member 3 is arranged in the accommodating cavity 1001 and is provided with a water passage 333 which is in communication with the water inlet channel 12; the rotating member 3 rotates relative to the valve body 100 about the first axis which is parallel to the first direction D1 to change the communication state of the water passage 333 and the water outlet channel; in this embodiment, the rotating member 3 rotates to change the communication area of the water passage 333 and the water outlet channel.

[0074] Further, as shown in Figure 2 and Figure 3 , along the first direction D1, the rotating member 3 is arranged in the accommodating cavity 1001 in an axial limiting manner, and the outer wall of the rotating member 3 is provided with a first protrusion 336 or a groove which extends in a spiral shape. In this embodiment, the rotating member 3 is taken as an example in which the outer wall of the rotating member 3 is provided with a first protrusion 336 which extends in a spiral shape.

[0075] As shown in Figure 3 , the two ends of the rotating member 3 abut against the cavity walls at the two ends of the accommodating cavity 1001, i.e., the bottom walls of the first cavity 11 and the second cavity 22, respectively, so that the rotating member 3 is arranged in the accommodating cavity 1001 in an axial limiting manner through a simple structure.

[0076] Specifically, as shown in Figure 3 and 8 , the rotating member 3 comprises a second protrusion 31, a third protrusion 32 and a rotating member body 33. The rotating member body 33 extends along the first direction D1 and is a rotary body whose axis is parallel to the first direction D1. The rotating member body 33 is divided into a circular truncated cone segment 331 and a circular cylinder segment 332 along the first direction D1. The end of the rotating member body 33 which is close to the first water outlet channel 21 is the circular truncated cone segment 331, and the rest is the circular cylinder segment 332. The second protrusion 31 and the third protrusion 32 are arranged at the two ends of the rotating member body 33, respectively; specifically, the end face of the rotating member body 33 which is close to the first water outlet channel 21 is provided with the second protrusion 31, and the end face of the rotating member body 33 which is close to the water inlet channel 12 is uniformly provided with a plurality of third protrusions 32 in the circumferential direction. The second protrusion 31 and the third protrusion 32 abut against the cavity walls at the two ends of the accommodating cavity 1001 to arrange the rotating member 3 in the accommodating cavity 1001 in an axial limiting manner. In this embodiment, the second protrusion 31 and the third protrusion 32 are both spherical protrusions. Since the second protrusion 31 and the third protrusion 32 are arranged, the contact area of the rotating member 3 and the cavity wall of the accommodating cavity 1001 is small, the area which is affected by friction and is prone to wear is also small when the rotating member 3 rotates, and the rotating member body 33 is not prone to wear, thereby affecting the normal use of the valve.

[0077] As shown in Figure 3As shown, a water passage 333 is provided on the rotating body 33. The water inlet of the water passage 333 opens at the end of the rotating body 33 near the water inlet 12, and the water outlet of the water passage 333 opens on the side wall of the rotating body 33 near the first water outlet 21. Since the water inlet of the water passage 333 opens at the end of the rotating body 33 near the water inlet 12, and the end face of this end is annular, several third protrusions 32 are evenly distributed circumferentially. When the rotating body 33 rotates, the force on each third protrusion 33 is relatively uniform.

[0078] Among them, such as Figure 8 As shown, the outlet end of the water passage 333 includes a first water inlet 334 and a second water inlet 335 arranged circumferentially on the rotating member 3. The first water inlet 334 and the second water inlet 335 are connected and interconnected. The opening size of the second water inlet 335 gradually decreases in the direction away from the first water inlet 334. The second water inlet 335 is provided so that the water flow is a gradual process when the rotating member 3 is rotated and adjusted. In this embodiment, the second water inlet 335 is provided on both sides of the first water inlet 334, so that the water flow can be gradually changed regardless of whether the rotating member 3 rotates clockwise or counterclockwise. When the rotating member 3 rotates relative to the valve body 100, it changes the communication area between the outlet end of the water passage 333 and the water passage.

[0079] In this embodiment, as Figure 8 As shown, the rotating body 33 has a first protrusion 336 on the outer wall of the cylindrical section 332.

[0080] like Figure 3 and Figure 9 As shown, the push button 4 is slidably disposed in the sliding hole 1002 along the first direction D1. Specifically, the push button 4 includes an operating body 41 and a second claw 42 fixedly connected to each other. The second claw 42 is fixedly connected to the bottom wall of the operating body 41.

[0081] like Figure 2 and Figure 3 As shown, the transmission component 10 is positioned between the push button 4 and the rotating component 3, so that when the push button 4 slides, it drives the rotating component 3 to rotate around the first axis. In this embodiment, by setting the transmission component 10 between the push button 4 and the rotating component 3, when the push button 4 slides, the driving force of the push button 4 along the sliding direction is converted into a force that drives the rotating component 3 to rotate along the first axis through the transmission component 10. This allows the rotating component 3 to be rotated by the sliding of the push button 4, changing the connection state between the water passage 333 and the water outlet. During the rotation process, the thrust is not affected by the water pressure and can always maintain the initial thrust.

[0082] Specifically, such as Figure 2 and Figure 3As shown, the transmission member 10 is fixedly connected with the push button 4, and is driven to slide along the first direction by the push button 4; and the transmission member 10 is screwedly connected with the rotating member 3. The transmission member 10 is provided with a screw portion 102 which is matched with the first protrusion 336, so that the screw connection between the rotating member 3 and the transmission member 10 is realized by simple structure. In the embodiment, the screw portion 102 is matched with the first protrusion 336.

[0083] In actual use, as shown in Figure 9 The transmission member 10 includes a fixed portion 101 and a screw portion 102. The fixed portion 101 includes a plate body 1011 and a second protrusion 1012. The plate body 1011 extends along the first direction D1. The second protrusion 1012 is fixedly connected with the middle portion of the plate body 1011 at one end, and is fixedly connected with the outer wall of the screw portion 102 at the other end. The second protrusion 1012 is provided with a second clamping groove 1013 which penetrates the plate body 1011. The screw portion 102 is annular, and is sleeved on the rotating member 3. The inner wall of the screw portion 102 is provided with a screw groove 1021 which is matched with the first protrusion 336 on the rotating member 3. When the screw portion 102 is sleeved on the rotating member 3, the second protrusion 1012 partially extends out of the sliding hole 1002 of the valve body 100, and the plate body 1011 is located outside the sliding hole 1002. The first protrusion 17 on the first seat body 1 is located below the plate body 1011, and the first protrusion 17 is arranged to reduce the gap between the plate body 1011 and the first seat body 1, so as to avoid the shaking of the transmission member 10.

[0084] It should be understood that the screw connection between the transmission member 10 and the rotating member 3 is not limited to the connection mode in the embodiment. For example, the first protrusion 336 on the rotating member 3 is replaced by a screw-shaped groove, and the screw groove 1021 on the transmission member 10 is replaced by a protrusion which extends in a screw shape. As long as the transmission member 10 and the rotating member 3 are matched in the circumferential direction, and the matching in the circumferential direction can drive the rotating member 3 to rotate when the transmission member 10 slides along the axial direction of the rotating member 3, it should be within the protection scope of the present application.

[0085] As shown in Figure 3 and Figure 4As shown, the first seal 5 and the second seal 6 are sleeved on the rotating member 3. When the rotating member 3 is arranged in the accommodating cavity 1001, the first seal 5 and the second seal 6 abut against the cavity wall of the accommodating cavity 1001, so as to divide the accommodating cavity 1001 into the water outlet cavity 1003, the rotating cavity 1004 and the water inlet cavity 1005 arranged along the first direction D1. The cavity between the first seal 5 and the second seal 6 of the accommodating cavity 1001 forms the rotating cavity 1004, and the sliding hole 1002 communicates with the rotating cavity 1004. The cavity between the end of the accommodating cavity 1001 close to the first water outlet 21 and the first sealing ring forms the water outlet cavity 1003, and the water inlet end of the first water outlet 21 is opened on the side wall of the water outlet cavity 1003. The cavity between the end of the accommodating cavity 1001 close to the water inlet end and the second seal 6 forms the water inlet cavity 1005. The water inlet channel 12 is opposite to the water inlet cavity 1005. The water inlet end of the water passing channel 333 is located in the water inlet cavity 1005, and the water outlet end is located in the water outlet cavity 1003.

[0086] In actual use, as shown in Figure 3 and Figure 4 The inner diameter of the rotating cavity 1004 is greater than the outer diameter of the rotating member 3 located in the rotating cavity 1004, so as to provide space for installing the transmission member 10. The water outlet cavity 1003 is adapted to the part of the rotating member 3 located in the water outlet cavity 1003. As shown in Figure 4 and Figure 7 The water outlet cavity 1003 includes the first groove 1006 and the first hole 1007 arranged along the first direction D1 and communicating with each other, and the first hole 1007 is closer to the rotating cavity 1004 than the first groove 1006. In the direction perpendicular to the first direction D1, the width of the first groove 1006 gradually decreases in the direction away from the first hole 1007. In this embodiment, the first groove 1006 is in the shape of a circular truncated cone, which is adapted to the circular truncated cone section 331 of the rotating member body 33, and the first hole 1007 is adapted to the part of the cylindrical section 332 of the rotating member body 33 extending into the water outlet cavity 1003. In this way, the gap between the water outlet cavity 1003 and the end surface of the rotating member 3 is as small as possible. If the water flowing out of the water outlet end of the water passing channel 333 leaks into the water outlet cavity 1003, it will not accumulate too much water in the water outlet cavity 1003.

[0087] Specifically, as shown in Figure 3 and Figure 4The first seal 5 is sleeved on the cylindrical section 332 of the rotating member body 33 near the circular truncated cone section 331, and is used to seal the water outlet cavity 1003 and the rotating cavity 1004. The second seal 6 is sleeved on the cylindrical section 332 of the rotating member body 33 near one end of the water inlet channel 12, and is used to seal the water inlet cavity 1005 and the rotating cavity 1004. The first seal 5 and the second seal 6 are arranged to seal the rotating cavity 1004 from the water outlet cavity 1003 and the water inlet cavity 1005, so that the rotating cavity 1004 is completely isolated from water, and water cannot enter the rotating cavity 1004. When the push button 4 drives the transmission member 10 to slide, the rotating cavity 1004 will not be affected by water pressure.

[0088] As shown in Figure 2 The fixed member includes a first fixed member 7 and a second fixed member 8.

[0089] As shown in Figure 3 and Figure 4 The first fixed member 7 is sleeved on the rotating member body 33 and abuts against the first seal 5 and the third limiting surface 23. When the rotating member 3 is placed in the accommodating cavity 1001, the side wall of the first seal 5 abuts against the inner wall of the second cavity 22, and the first seal 5 is clamped between the fourth limiting surface 24 and the first fixed member 7. In this way, the first seal 5 can be prevented from sliding in the first direction D1.

[0090] As shown in Figure 3 and Figure 4 The second fixed member 8 is sleeved on the rotating member body 33 and abuts against the second seal 6 and the first limiting surface 13. When the rotating member 3 is placed in the accommodating cavity 1001, the side wall of the second seal 6 abuts against the inner wall of the first cavity 11, and the second seal 6 is clamped between the second limiting surface 14 and the second fixed member 8. In this way, the second seal 6 can be prevented from sliding in the first direction D1.

[0091] When the valve of the present embodiment is assembled:

[0092] As shown in Figures 1 to 12As shown, firstly, the helical portion 102 of the transmission component 10 is fitted onto the rotating component body 33, and the helical groove 1021 of the helical portion 102 and the first protrusion 336 of the rotating component body 33 are helically engaged. Next, the first sealing member 5, the second sealing member 6, the first fixing member 7, and the second fixing member 8 are fitted onto the rotating component body 33. Then, one end of the rotating component body 33 with the frustum section 331 is inserted into the second cavity 22 of the second seat 2, and the side wall of the first sealing member 5 is placed against the inner wall of the second cavity 22, with the first sealing member 5 sandwiched between the fourth limiting surface 24 and the first fixing member 7. Next, the other end of the rotating body 33 is inserted into the first cavity 11 of the first seat 1. The first slot 16 of the first seat 1 and the first claw 25 of the second seat 2 engage to form the receiving cavity 1001 and the sliding hole 1002. The second protrusion 31 and the third protrusion 32 of the rotating body 33 abut against the cavity walls at both ends of the receiving cavity 1001, and the second protrusion 1012 of the fixing part 101 on the transmission member 10 extends out of the sliding hole 1002. The side wall of the second sealing member 6 abuts against the inner wall of the first cavity 11, and the second sealing member 6 is sandwiched between the second limiting surface 14 and the second fixing member 8. Finally, the second claw 42 of the push button 4 engages with the second slot 1013 on the fixing part 101, and the installation is completed.

[0093] When using the valve in this embodiment:

[0094] like Figures 1 to 12 As shown, by pushing the operating body 41 of the push button 4, the push button 4 causes the transmission component 10 to slide along the first direction D1. Since the rotating component 3 is axially limited and installed in the accommodating cavity 1001, the rotating component 3 cannot slide along the axis of the transmission component 10. Furthermore, due to the helical engagement between the rotating component 3 and the transmission component 10, when the rotating component 3 cannot slide, the transmission component 10 will drive the rotating component 3 to rotate, thereby changing the communication area between the water passage 333 and the water outlet. Compared with the sliding adjustment in the prior art, the helical engagement between the push button 4 and the transmission component 10, and the fixed connection between the push button 4 and the transmission component 10, allows the push button 4 to drive the rotating component 3 to rotate through sliding. During the rotation, it is not affected by water pressure and can always maintain the initial thrust.

[0095] Figure 10 This is a schematic diagram of the valve in the first outlet state, at which time the valve has the largest flow rate, the first water inlet 334 is directly opposite the inlet end of the first outlet channel 21, and the connection area between the water inlet channel 333 and the first outlet channel 21 is the largest.

[0096] Figure 11 This is a schematic diagram of the valve in the second water outlet state. At this time, the rotating part 3 has been rotated by a certain angle, and the connection area between the water passage 333 and the first water outlet 21 has become smaller.

[0097] Figure 12 This is a schematic diagram of the valve in the third outlet state, at which point the valve flow rate is at its minimum, and the rotating part 3 completely blocks the inlet end of the first outlet channel 21.

[0098] Example 2:

[0099] like Figure 13 As shown, the main difference between this embodiment and Embodiment 1 is that in this embodiment, the second seat 2 has at least two water outlet channels. The rotating member 3 rotates around the first axis to change the communication relationship between each water outlet channel and the water passage 333 and / or the communication area between the water passage 333 and each water outlet channel. Specifically, in addition to the first water outlet channel 21, the water outlet channel also includes a second water outlet channel 28. The rotating member 3 rotates around the first axis to change the communication relationship between each water outlet channel and the water passage 333 and the communication area between the water passage 333 and each water outlet channel.

[0100] It should be understood that those skilled in the art can, by reasonably setting the positions of each water outlet, achieve only the change in the connection between each water outlet and the water passage 333 when the rotating member 3 rotates, and only the change in the connection area between the water passage 333 and each water outlet when the rotating member 3 rotates. Therefore, these two situations will not be described in detail in this embodiment.

[0101] Among them, such as Figure 13 As shown, the second water outlet 28 is provided on the second base 2 and extends along the first direction D1. The water inlet of the second water outlet 28 opens into the side wall of the water outlet cavity 1003. The water outlet of the second water outlet 28 is away from the opening of the second cavity 22.

[0102] In this embodiment, as Figure 13 As shown, the first water outlet 21 and the second water outlet 28 are symmetrically arranged along an axis of symmetry parallel to the first direction D1.

[0103] like Figure 14 As shown, this embodiment also includes an elastic sealing member 9. The outer wall of the rotating member 3 facing away from the first water outlet 334 is provided with an installation groove 337 for installing the elastic sealing member 9.

[0104] Compared with the valve in Embodiment 1, the installation steps of the valve in this embodiment are different. Before installing the rotating body 33 into the second cavity 22 of the second seat 2, the elastic sealing member 9 needs to be installed on the mounting groove 337; the rest of the installation steps are the same as those of the valve in Embodiment 1.

[0105] When using the valve in this embodiment:

[0106] like Figures 1 to 16As shown, by pushing the push button 4, the driving transmission component 10 of the push button 4 slides along the first direction D1. Since the rotating component 3 is axially limited and installed in the accommodating cavity 1001, the rotating component 3 cannot slide with the push button 4 when the transmission component 10 slides along the axial direction of the rotating component 3. Furthermore, due to the helical fit between the rotating component 3 and the transmission component 10, when the rotating component 3 cannot slide, the transmission component 10 will drive the rotating component 3 to rotate relative to the valve body 100, changing the connection relationship between each water outlet and the water passage 333 and the connection area between the water passage 333 and each water outlet, that is, changing the connection relationship and connection area between the first water outlet 334 and the second water outlet 335 and each water outlet. Compared with the sliding adjustment in the prior art, by the helical fit between the transmission component 10 and the rotating component 3, and by fixing the push button 4 to the transmission component 10, the push button 4 drives the rotating component 3 to rotate by sliding. During the rotation, it will not be affected by water pressure and can always maintain the initial thrust.

[0107] Figure 14 This is a schematic diagram of the valve in the first water outlet state. At this time, the first water inlet 334 is directly opposite the water inlet end of the first water outlet channel 21. The connection area between the water inlet channel 333 and the first water outlet channel 21 is the largest. The elastic sealing member 9 blocks the water inlet end of the second water outlet channel 28. At this time, the valve is in the state of water outlet from the first water outlet channel 21.

[0108] Figure 15 This is a schematic diagram of the valve in the second water outlet state. At this time, the second water outlets 335 on both sides of the first water outlet 334 are connected to the first water outlet 21 and the second water outlet 28 respectively. At this time, the valve is in the state where water is flowing out of both the first water outlet 21 and the second water outlet 28.

[0109] Figure 16 This is a schematic diagram of the valve in the third water outlet state. At this time, the first water outlet 334 is directly opposite the water inlet of the second water outlet 28. The water outlet 333 and the second water outlet 28 have the largest connection area. The elastic sealing member 9 blocks the water outlet of the first water outlet 21. At this time, the valve is in the state of water outlet of the second water outlet 28.

[0110] like Figures 14 to 16 When rotating part 3 rotates at Figure 14 The positions shown and Figure 16 Between the positions shown, the connection area between the water passage 333 and the first outlet 21 and the second outlet 28 changes. Therefore, the valve in this embodiment can both change the connection state between the water passage 333 and each outlet and change the connection area between the water passage 333 and each outlet.

[0111] Based on this embodiment, if only the connection between the water passage 333 and each water outlet channel needs to be changed, then it is only necessary to reduce the area of ​​the water outlet end of the water passage 333, so that... Figure 15In the shown state, the first and second water passages 334 and 335 are not communicated with the first and second water outlets 21 and 28. At this time, the valve has only two states of water outlet of the first water outlet 21 and water outlet of the second water outlet 28.

[0112] If only the communication area of the water passage 333 with each water outlet is to be changed based on the embodiment, the area of the water outlet end of the water passage 333 is only needed to be increased, so that the water passage 333 can be communicated with the first and second water outlets no matter the rotating member 3 is rotated to which position. At this time, the communication area of the first and second water outlets 21 and 28 is changed constantly when the rotating member 3 is rotated.

[0113] It should be understood that based on the valve of the embodiment, the person skilled in the art can also make other improvements so that the valve of the embodiment only changes the communication relationship of the water passage 333 with each water outlet or only changes the communication area of the water passage 333 with each water outlet. It is not limited to the two ways listed above.

[0114] The embodiment makes the function of the valve changed from flow regulation to water outlet state regulation by adding a water outlet based on the embodiment one. It is illustrated that the valve of the application has strong commonality and saves cost. The valve of the embodiment has the rest beneficial effects of the valve of the embodiment one except the difference in function.

[0115] Embodiment three:

[0116] The water outlet device (not shown in the figure) comprises the valve of the embodiment one or two, and the water outlet device is provided with a water inlet pipeline and a water outlet pipeline matched with the water outlet of the valve; the valve is arranged in the water outlet device, the water inlet 12 is communicated with the water inlet pipeline, and the water outlet is communicated with the corresponding water outlet pipeline.

[0117] In the embodiment, the water outlet device can be a shower, a faucet or a spray gun, especially some water outlet devices which can be used by hand. By arranging the valve of the embodiment one or two on the handle, the flow regulation or water outlet state regulation can be realized by the push button 4, and the total switch is not needed to be adjusted, which is more convenient to use.
