The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.
[0101] like Figures 1 to 5 As shown, Figure 1 The diagram shown is a schematic view of a switching mechanism 1 according to an embodiment of the present invention. Figure 2 The diagram shown is a schematic representation of the switching mechanism 1 according to another embodiment of the present invention. Figure 3 The diagram shown is a schematic representation of the switching mechanism 1 according to an embodiment of the present invention from another perspective. Figure 4 The diagram shown is an exploded view of the switching mechanism 1 according to an embodiment of the present invention. Figure 5 The diagram shown is an exploded view of the switching mechanism 1 according to another embodiment of the present invention.
[0102] The switching mechanism 1 of this embodiment includes a housing 100, multiple water valves 200, a swing member 300, an operating member 500, and a linkage member 400. It should be noted that the switching mechanism 1 of this embodiment can be installed on a water outlet device to switch the water outlet state of the device, for example, switching between shower water, massage water, or a mixture of shower water and massage water.
[0103] It is understood that the water outlet device of the present invention can be applied to bathroom shower heads, car wash water guns, kitchen faucets or other suitable application scenarios, and the present invention does not make any special limitations on this.
[0104] The housing 100 has a hollow chamber 101 (e.g. Figure 6 It includes an inlet channel 130 and multiple outlet channels 140 connected to the hollow chamber 101. The inlet channel 130 can be connected to an external water source to supply liquid to the hollow chamber 101.
[0105] The housing 100 may include a base 110 and a water distribution body 120, which are connected to form the hollow chamber 101. That is, the base 110 and the water distribution body 120 are separate structures, which can be connected by bolts, snap-fit connections, etc. Of course, the base 110 and the water distribution body 120 can also be an integral structure, and the present invention does not particularly limit this.
[0106] In this embodiment, the housing 100 includes a base 110 and a water distribution body 120, which are separate structures. A water inlet channel 130 is disposed on the base 110 and connects to the hollow chamber 101, allowing external water to be supplied to the hollow chamber 101 through the water inlet channel 130. Multiple water outlet channels 140 are disposed on the water distribution body 120 to discharge liquid from the hollow chamber 101. Each water outlet channel 140 corresponds to a multiple water valve 200, enabling each water valve 200 to block or open each water outlet channel 140, thus switching the water outlet state.
[0107] Multiple water valves 200 are movably disposed in the hollow cavity 101 and are correspondingly disposed with multiple water outlet channels 140. Each water valve 200 has a blocked state and an open state relative to each water outlet channel 140.
[0108] In this embodiment, there are three water inlet valves 200, and correspondingly, there are also three water outlet channels 140. Of course, the number of water inlet valves 200 and water outlet channels 140 can also be two, four, or other numbers, and the present invention does not limit this.
[0109] Each water valve 200 is movable relative to its corresponding water outlet channel 140, allowing the water valve 200 to switch between a blocked state and an open state relative to the water outlet channel 140. Specifically, when the water valve 200 blocks the water outlet channel 140, the liquid in the hollow chamber 101 cannot flow out from the blocked water outlet channel 140, but can only flow out from the unblocked water outlet channel 140.
[0110] The swing member 300 is oscillatingly disposed within the housing 100 and is linked to multiple water valves 200 to drive each water valve 200 to move, such that when one of the multiple water valves 200 is in the open state, the other water valves 200 are in the closed state. In this embodiment, the oscillating movement of the swing member 300 within the housing 100 can drive each water valve 200 to switch between a closed state and an open state, such that when one water valve 200 is in the open state, the other water valves 200 are in the closed state. Thus, as described above, when a water valve 200 is in the open state, that is, the water outlet channel 140 corresponding to the water valve 200 is not blocked, the liquid in the hollow cavity 101 can flow out from the water outlet channel 140, but cannot flow out from other water outlet channels 140. When the swing member 300 oscillates, it can selectively drive one of the multiple water valves 200 to the open state, while the other water valves 200 are in the closed state. In this way, by swinging the swinging component 300, multiple water outlet channels 140 can be opened in rotation, achieving the effect of switching water outlets.
[0111] An operating element 500 is disposed on the housing 100. A linkage 400 is connected to the operating element 500 and the swinging element 300 so that when the operating element 500 is operated, the swinging element 300 can be driven to swing through the linkage 400.
[0112] like Figures 4 to 7 As shown, Figure 6 What is shown is Figure 3 Sectional view along the middle AA. Figure 7 What is shown is Figure 3 A cross-sectional view along the middle BB.
[0113] The swing member 300 includes a main body 310 and a first spherical structure 320 disposed at one end of the main body 310. The first spherical structure 320 and the inner wall surface of the hollow cavity 101 form a spherical pair, so that the swing member 300 swings around a sphere center O located in the hollow cavity 101.
[0114] In this embodiment, the water distribution body 120 has a curved concave structure on the side facing the seat 110. The first spherical structure 320 of the swing member 300 and the curved concave structure form a spherical pair, so that the swing member 300 can swing around a sphere center O located in the hollow cavity 101, thereby driving the movement of multiple water valves 200.
[0115] like Figure 4 and Figure 8 As shown, Figure 8 The diagram shown illustrates a switching mechanism 1 according to an embodiment of the present invention, including the removal operation member 500 and the base 110. A plurality of water valves 200 are evenly arranged along the circumferential direction of the sphere center O. In other words, the plurality of water valves 200 surround the body 310 of the swing member 300 and are evenly arranged along the circumferential direction.
[0116] The swing member 300 also includes a plurality of drive units 330, which are disposed on the side of the main body 310 and are respectively linked to a plurality of water valves 200 to drive the plurality of water valves 200 to switch between a blocked state and an open state.
[0117] Multiple drive units 330 also surround the main body 310 and are evenly arranged along the circumferential direction. The multiple drive units 330 are correspondingly arranged with multiple water valves 200 to drive the movement of the multiple water valves 200 respectively. Specifically, as... Figure 8 As shown, in this embodiment, there are three water valves 200. When one of the driving parts 330 of the swing member 300 drives one of the water valves 200 to move upward, since the three driving parts 330 are evenly arranged along the circumferential direction, the other two driving parts 330 will swing in the opposite direction to the movement direction of the one driving part 330, thereby driving the other two water valves 200 to move downward and be in a blocked state.
[0118] In this way, by swinging the swinging member 300, different water valves 200 can be driven to open, while the remaining water valves 200 are blocked.
[0119] like Figure 5 , Figure 7 and Figure 9 As shown, Figure 9 The diagram shown is a schematic representation of a seat 110 according to an embodiment of the present invention. Each water valve 200 includes a first sealing portion 210, a second sealing portion 220, and a connecting portion 230 disposed between the first sealing portion 210 and the second sealing portion 220. In this embodiment, the connecting portion 230 may have a rod-like structure, and the cross-sectional area of the connecting portion 230 is smaller than the cross-sectional area of the first sealing portion 210 and the second sealing portion 220, making the water valve 200 approximately dumbbell-shaped. The cross-sectional areas of the first sealing portion 210 and the second sealing portion 220 are equal.
[0120] like Figure 4 As shown, the driving part 330 of the swing member 300 can be in a semi-annular structure. The driving part 330 can be engaged with the connecting part 230 of the water valve 200 and is disposed between the first sealing part 210 and the second sealing part 220. Both opposite sides of the driving part 330 have protruding structures. When the swing member 300 swings up and down, the two protruding structures of the driving part 330 respectively abut against the first sealing part 210 and the second sealing part 220, causing the water valve 200 to switch between a blocked state and an open state.
[0121] like Figure 9 As shown, the inner wall of the hollow chamber 101 is provided with a plurality of grooves 112, and the plurality of grooves 112 are correspondingly provided with a plurality of water valves 200. The first sealing part 210 can seal with the inner wall of the water outlet channel 140, and the second sealing part 220 can seal with the side wall of the groove 112.
[0122] like Figure 7 As shown, a first sealing element 710 and a first friction surface 810 are provided between the inner wall surface of the first sealing part 210 and the water outlet channel 140, and the first sealing element 710 and the first friction surface 810 are slidably sealed together.
[0123] A second sealing element 720 and a second friction surface 820 are provided between the sidewall of the second sealing part 220 and the groove 112. The second sealing element 720 and the second friction surface 820 are slidably sealed together, and the second sealing part 220 and the groove 112 form a liquid storage cavity 360.
[0124] The water valve 200 also includes a through hole 240, which passes through the first sealing part 210, the connecting part 230 and the second sealing part 220, so that the liquid storage chamber 360 is connected to the water outlet channel 140 through the through hole 240.
[0125] The first friction surface 810 is the outer peripheral surface of the first sealing part 210 or the inner wall surface of the water outlet channel 140, and the second friction surface 820 is the outer peripheral surface of the second sealing part 220 or the side wall of the groove 112.
[0126] In this embodiment, a first sealing member 710 is sleeved on the outer periphery of the first sealing part 210, through which the first sealing part 210 and the inner wall surface of the water outlet channel 140 are sealed together. A second sealing member 720 is sleeved on the outer periphery of the second sealing part 220, through which the second sealing part 220 and the side wall of the groove 112 are sealed together.
[0127] In this embodiment, the first friction surface 810 is the inner wall surface of the water outlet channel 140. The first sealing member 710 and the first friction surface 810 are slidably sealed together. That is, when the water valve 200 moves up and down, the first sealing member 710 moves up and down with the first sealing part 210, and then seals with the inner wall surface of the water outlet channel 140.
[0128] Similarly, the second friction surface 820 is the side wall of the groove 112, and the second seal 720 and the second friction surface 820 are slidably sealed together. That is, when the water valve 200 moves up and down, the second seal 720 moves up and down with the second sealing part 220, and then seals with the side wall of the groove 112.
[0129] Of course, in other embodiments, the first friction surface 810 can also be the outer peripheral surface of the first sealing part 210, and the first sealing member 710 is fixed in the groove of the water outlet channel 140. When the water valve 200 moves up and down, the first sealing part 210 moves up and down, while the first sealing member 710 remains stationary, ultimately achieving a slidable sealing fit between the outer peripheral surface of the first sealing part 210 and the first sealing member 710.
[0130] The second friction surface 820 can also be the outer peripheral surface of the second sealing part 220, and the second sealing element 720 is fixed in the groove of the side wall of the groove 112. When the water valve 200 moves up and down, the second sealing part 220 moves up and down, while the second sealing element 720 remains stationary, ultimately achieving a slidable sealing fit between the outer peripheral surface of the second sealing part 220 and the second sealing element 720.
[0131] Please continue reading. Figure 7 The contact area between the first seal 710 and the first friction surface 810 is equal to the contact area between the second seal 720 and the second friction surface 820.
[0132] When the water valve 200 is open, the liquid in the hollow chamber 101 can flow to the storage chamber 360 through the through hole 240. In this way, both the side of the first sealing part 210 facing away from the second sealing part 220 and the side of the second sealing part 220 facing away from the first sealing part 210 can be filled with liquid. Since the contact area between the first sealing member 710 and the first friction surface 810 is equal to the contact area between the second sealing member 720 and the second friction surface 820, the water valve 200 is in a state of water pressure balance when it is open.
[0133] Similarly, when the water valve 200 is in the blocked state, it is also in a state of water pressure balance.
[0134] In this way, the water valve 200 is in a state of water pressure balance in both the blocked and open states. When the water valve 200 switches back and forth between the blocked and open states, since both states are in a state of water pressure balance, the water valve 200 moves more smoothly and is not subject to the reaction force of water pressure. This reduces the switching force required by the user to operate the operating component 500, achieving the effect of saving effort.
[0135] like Figure 4 and Figure 5 As shown, the housing 100 includes multiple sets of corresponding first perforations 113 and second perforations 121, and both the first perforations 113 and the second perforations 121 are connected to the hollow cavity 101.
[0136] In this embodiment, there can be three sets of corresponding first perforations 113 and second perforations 121. The first perforations 113 are disposed on the base 110, and the second perforations 121 are disposed on the water distribution body 120. In other words, the base 110 has three first perforations 113, and the water distribution body 120 has three second perforations 121. When the base 110 and the water distribution body 120 are connected, the three first perforations 113 are respectively disposed in relation to the three second perforations 121.
[0137] The linkage 400 includes a plurality of slide rods 410, each slide rod 410 including a rod body 411 and a pressing part 412 connected to the rod body 411. Each rod body 411 is slidably inserted into each set of corresponding first through holes 113 and second through holes 121, and each pressing part 412 presses against different positions of the swing member 300.
[0138] like Figure 6 and Figure 8As shown, in this embodiment, there are three slide rods 410, which are slidably inserted into the corresponding first through hole 113 and second through hole 121. The three slide rods 410 surround the main body 310 of the swing member 300 and are evenly arranged along the circumferential direction, and are located between two adjacent water valves 200. In other words, the three slide rods 410 and the three water valves 200 are arranged alternately in the circumferential direction.
[0139] Meanwhile, in the circumferential direction, the position where the swing member 300 is pressed by the pressing part 412 of the slide rod 410 is located between adjacent drive parts 330. That is, along the circumferential direction of the swing member 300, the three drive parts 330 and the three positions pressed by the pressing part 412 of the slide rod 410 are arranged alternately in sequence.
[0140] Thus, when one of the three sliding rods 410 moves downward, the pressing part 412 of that sliding rod 410 presses against the swing member 300, causing the swing member 300 to swing. Due to the relative positional relationship of the sliding rod 410, the water valve 200, and the driving part 330 of the swing member 300, the swing member 300, through the driving part 330, drives the water valve 200, which is opposite to the sliding rod 410, to move upward, while pressing down the other water valves 200, so that the water valve 200 opposite to the sliding rod 410 is in the open state, while the other water valves 200 are in the closed state.
[0141] When the other slide bars 410 move, the movement of the water valve 200 is similar to that described above, and will not be repeated here.
[0142] like Figure 6 As shown, one end of the rod 411 can be slidably sealed with the first through hole 113, and the other end of the rod 411 can be slidably sealed with the second through hole 121.
[0143] A third seal 730 and a third friction surface 830 are provided between the rod body 411 and the hole wall of the first through hole 113, and the third seal 730 and the third friction surface 830 are slidably sealed together.
[0144] A fourth seal 740 and a fourth friction surface 840 are provided between the rod body 411 and the hole wall of the second through hole 121, and the fourth seal 740 and the fourth friction surface 840 are slidably sealed together.
[0145] The third friction surface 830 is the outer wall of the rod 411 or the wall of the first through hole 113, and the fourth friction surface 840 is the outer wall of the rod 411 or the wall of the second through hole 121.
[0146] Continue reading Figure 6In this embodiment, the third friction surface 830 is the outer wall of the rod 411. A third sealing element 730 is sleeved on the outside of the rod 411, and the third sealing element 730 and the outer wall of the rod 411 are slidably sealed together. The third sealing element 730 is disposed in a groove in the wall of the first through hole 113. When the rod 411 moves up and down, the third sealing element 730 does not move with the rod 411.
[0147] The fourth friction surface 840 is the outer wall of the rod 411. A fourth sealing element 740 is fitted onto the outside of the rod 411, and the fourth sealing element 740 and the outer wall of the rod 411 are slidably sealed together. The fourth sealing element 740 is disposed in a groove in the wall of the second through hole 121. When the rod 411 moves up and down, the fourth sealing element 740 does not move with the rod 411.
[0148] Of course, in other embodiments, the third friction surface 830 can also be the wall of the first through hole 113, and the fourth friction surface 840 can also be the wall of the second through hole 121. Correspondingly, slots are respectively provided at both ends of the rod 411 to accommodate the third seal 730 and the fourth seal 740. When the rod 411 moves up and down, it can drive the third seal 730 and the fourth seal 740 to move together, and slidably seal with the walls of the first through hole 113 and the second through hole 121, respectively.
[0149] The contact area between the third seal 730 and the third friction surface 830 is equal to the contact area between the fourth seal 740 and the fourth friction surface 840. Thus, each slide rod 410 is in a state of water pressure balance, meaning that regardless of its position, the slide rod 410 can remain in that position without moving up or down.
[0150] like Figure 4 and Figure 6 As shown, each rod 411 has a locking part 420 at one end, and the operating member 500 has multiple locking slots 501, with each locking part 420 being movably locked into each locking slot 501.
[0151] like Figure 3 and Figure 12As shown, the operating component 500 includes multiple independently configured operating buttons 510, each with a snap-fit groove 501. When the operator presses one of the operating buttons 510, the button and the connected slide rod 410 move. During the downward movement of the slide rod 410, the pressing part 412 of the slide rod 410 presses down against the mating part 370 of the swing component 300, causing the swing component 300 to swing to one side. This causes one of the driving parts 330, which is opposite to the mating part 370, to drive the corresponding water valve 200 upward to achieve water flow. During the swing of the swing component 300, the remaining water valves 200 move downward under the drive of the remaining driving parts 330 to achieve water stop. At the same time, during the swing of the swing component 300, the remaining mating parts 370 of the swing component 300 can drive the remaining slide rods 410 upward, thereby driving the other operating buttons 510 upward and returning them to their initial positions.
[0152] like Figures 4 to 6 As shown, a second recess 430 is provided between the rod body 411 and the locking part 420; the switching mechanism 1 also includes a plurality of second positioning components 620; the outer wall of the housing 100 is provided with a plurality of second receiving grooves 150, and the plurality of second positioning components 620 are respectively housed in the plurality of second receiving grooves 150 and can be respectively positioned in the plurality of second recesses 430 to position the slide rod 410 in the pressed state. By setting the second positioning components 620 and cooperating with the second recesses 430 of the slide rod 410, the slide rod 410 can be reliably held in the pressed position.
[0153] Furthermore, the second positioning component 620 includes a second positioning pin 621 and a second elastic member 622. The second elastic member 622 abuts against the second positioning pin 621 and the groove wall of the second receiving groove 150, respectively, so that the second positioning pin 621 can be retractably accommodated in the second receiving groove 150. When the slide rod 410 needs to be positioned, under the action of the second elastic member 622, one end of the second positioning pin 621 is engaged in the second recess 430 of the slide rod 410 to achieve the positioning function.
[0154] like Figures 4 to 6 As shown, the main body 310 of the oscillating member 300, away from the first spherical structure 320, has a second spherical structure 340 at its other end. The second spherical structure 340 and the inner wall surface of the hollow cavity 101 form a spherical pair. When the oscillating member 300 oscillates within the hollow cavity 101, the spherical pairs formed by the first spherical structure 320 and the second spherical structure 340 with the hollow cavity 101 allow the oscillating member 300 to oscillate smoothly. The first spherical structure 320 and the second spherical structure 340 are concentrically arranged.
[0155] like Figure 9 As shown, the inner wall surface of the hollow cavity 101 is provided with a plurality of first recesses 111.
[0156] Return to the reference Figures 4 to 6 The second spherical structure 340 is provided with a first receiving groove 350. The switching mechanism 1 also includes a first positioning component 610, which is housed in the first receiving groove 350 and can be selectively positioned in multiple first recesses 111 so that when different water valves 200 are in the open state, the first positioning component 610 positions the swing member 300 at different positions. By positioning the first positioning component 610 in multiple first recesses 111, the accuracy of the movement of the swing member 300 can be ensured. When the first positioning component 610 is positioned in one of the first recesses 111, the swing positioning function can be achieved.
[0157] Furthermore, the first positioning component 610 includes a first positioning pin 611 and a first elastic member 612. The two ends of the first elastic member 612 abut against the first positioning pin 611 and the bottom wall of the first receiving groove 350, respectively, so that the first positioning pin 611 can be retractably accommodated in the first receiving groove 350. When the swing member 300 swings to the set position, the first positioning pin 611, under the action of the first elastic member 612, can be engaged in the first recess 111 and emit a "click" sound to indicate to the operator that the swing member 300 has swung to the set position.
[0158] like Figure 10 and Figure 11 As shown, Figure 10 The diagram shown is a schematic diagram of a switching mechanism 1 according to another embodiment of the present invention. Figure 11 What is shown is Figure 10 A cross-sectional view along the CC axis. The outer wall of the housing 100 is provided with a ball head structure 160, which forms a spherical pair with the operating member 500, so that the operating member 500 can swing around the ball head structure 160 to press down multiple slide rods 410 respectively.
[0159] In another aspect, the present invention provides a water outlet device, including the switching mechanism 1 of any of the above embodiments.

[0160] In summary, the switching mechanism 1 and the water outlet device of the present invention have at least the following advantages and beneficial effects:
[0161] The switching mechanism 1 of this invention includes a housing 100, multiple water valves 200, a swing member 300, an operating member 500, and a linkage member 400. The linkage member 400 is linked to the operating member 500 and the swing member 300. The swing member 300 is movably disposed within the housing 100 and is linked to the multiple water valves 200. When the operating member 500 is operated, the linkage member 400 drives the swing member 300 to swing, so that when one of the multiple water valves 200 is in an open state, the other water valves 200 are in a closed state, achieving the effect of switching the water output. Compared with the technical solutions of switching mechanisms in related technologies, the switching mechanism 1 of this invention has the advantages of fewer components and a simpler structure.
[0162] Meanwhile, through the swing of the swing member 300 and the multiple water valves 200 linked to it, and the design that the contact area between the sealing element of the water valve 200 and the friction surface is equal, the switching force of the switching mechanism 1 in this embodiment of the invention is not affected by water pressure, and the switching is more labor-saving.
