DETAILED DESCRIPTION

[0045] In order to make the above objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the drawings. In the following description, a large number of specific details are set forth in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0046] The present application provides a water outlet switching mechanism in some embodiments, as shown in Figure 1 The water outlet switching mechanism can be applied to a water outlet device 10, such as a shower.

[0047] As shown in Figures 1 to 4 The water outlet switching mechanism includes a mechanism body 11 and a switching unit 20. The mechanism body 11 has a water flow passage. The switching unit 20 includes a switching piece 21, an elastic reset piece 22, a pressing piece 23 and a push block 24.

[0048] The switching piece 21 is slidably fitted on the mechanism body 11 in a first direction to control the water flow passage on and off. In some specific embodiments, the switching piece 21 is a rod-shaped structure, and the axial direction of the switching piece 21 is parallel to the first direction. The switching piece 21 slides back and forth in its own axial direction relative to the mechanism body 11 to switch the water flow passage on and off.

[0049] The elastic reset member 22 acts between the switching member 21 and the mechanism body 11 to enable the switching member 21 to slide in the first direction to block the water flow passage. For example, the elastic reset member 22 directly acts between the switching member 21 and the mechanism body 11, so that the switching member 21 is capable of sliding to the position of blocking the water flow passage under the elastic force of the elastic reset member 22. Alternatively, the elastic reset member 22 indirectly acts between the mechanism body 11 and the switching member 21, which means that the elastic reset member 22 transmits the acting force to the mechanism body 11 or the switching member 21 through an intermediate element. For example, the pressing member 23 can be used as the intermediate element to transmit the acting force of the elastic reset member 22 to the mechanism body 11.

[0050] The pressing member 23 is arranged on the mechanism body 11, and the pressing direction of the pressing member 23 is consistent with the first direction. As shown by the arrow F1 in Figure 5 、 Figure 8 and Figure 10 , the first direction is from top to bottom in the view angle.

[0051] As shown in Figures 2 to 4 , the push block 24 has a first inclined surface 2421 intersecting with the first direction, and the push block 24 is in sliding fit with the switching member 21, and the sliding direction of the push block 24 intersects with the first direction. The push block 24 has a second inclined surface 2411 arranged along the direction in which the push block 24 slides relative to the switching member 24, and the switching member 21 pushes against the second inclined surface 2411 when the switching member 21 slides in the first direction. The inclination directions of the second inclined surface 2411 and the first inclined surface 2421 relative to the first direction are opposite. It can be understood that the normal vector of the first inclined surface 2421 can be decomposed into a sub-vector perpendicular to the first direction, which is the first sub-vector. The normal vector of the second inclined surface 2411 can be decomposed into a sub-vector perpendicular to the first direction, which is the second sub-vector. The directions of the first sub-vector and the second sub-vector are opposite. Therefore, when the switching member 21 slides in the first direction, the moving direction of the push block 24 is opposite to the moving direction of the push block 24 when the pressing member 23 presses against the first inclined surface 2421.

[0052] When the switching member 21 slides in the first direction to block the water flow passage, the push block 24 slides relative to the limiting portion 16 to the position where the first inclined surface 2421 is located on the pressing path of the pressing member 23.

[0053] As shown in Figure 6 、 Figure 7 、 Figure 9 and Figure 11As shown, the mechanism body 11 also has a limiting part 16, which limits the push block 24 in the first direction. Under the limiting action of the limiting part 16, when the switching member 21 or the pressing member 23 moves along the first direction to apply force to the push block 24, the push block 24 cannot slide in the first direction. Therefore, the push block 24 slides relative to the switching member 21 or the pressing member 23, and the state is switched. In the water outlet device 10, the limiting part 16 can be part of the spray gun body.

[0054] Specifically, such as Figure 3 As shown, when the pressing member 23 is not pressed, the switching member 21 will slide along the first direction to the position of blocking the water flow channel under the action of the elastic reset member 22, and at this time, the first inclined surface 2421 of the push block 24 is located on the pressing path of the pressing member 23. When the switching member 21 slides along the first direction, the limiting part 16 prevents the push block 24 from sliding along the first direction, while the push block 24 can slide relative to the switching member 21, and the sliding direction intersects with the first direction. Therefore, the push block 24 can slide relative to the mechanism body 11 along the second direction. Figure 3 The direction indicated by the middle arrow F2 is the second direction. Figure 3 The diagram shows the structure when the switching element 21 blocks the water flow channel and the push block 24 has slid along the second direction to the first inclined surface 2421 located on the pressing path of the pressing element 23.

[0055] When it is necessary to open the water flow channel, such as Figure 4 As shown, when the pressing member 23 is pressed down, the pressing member 23 presses against the first inclined surface 2421, and the push block 24 slides in the opposite direction relative to the limiting part 16 in the second direction. Under the action of the push block 24, the switching member 21 overcomes the elastic force of the elastic reset member 22 and slides in the opposite direction in the first direction, so that the switching member 21 slides to the position where the water flow channel is open.

[0056] The switching of the water flow channel's on / off state is completed. The entire switching process mainly relies on the inclined surface cooperation between the push block 24, the pressing component 23, and the switching component 21. Unless the cooperating parts are worn, the ability to switch the water flow channel's on / off state is generally not lost, and the component cooperation has high reliability. Moreover, the close arrangement of each component makes the overall structure more compact, suitable for installation in small spaces such as shower heads.

[0057] like Figures 2 to 4 As shown, in some embodiments, the push block 24 has a mating portion 241 and two anti-slip portions 242. The mating portion 241 is slidably engaged with the switching member 21, and the two anti-slip portions 242 are respectively connected to both ends of the mating portion 241 along the sliding direction. When the mating portion 241 slides to its limit position relative to the switching member 21 along the sliding direction, the anti-slip portions 242 abut against the switching member 21 to prevent the mating portion 241 from continuing to slide.

[0058] As Figure 3 shown, when the engaging portion 241 slides to the limit position along the second direction, the left side stop portion 242 abuts against the switching piece 21 to prevent the push block 24 from continuing to slide along the second direction.

[0059] As Figure 4 shown, when the engaging portion 241 slides to the limit position along the second direction, the left side stop portion 242 abuts against the switching piece 21 to prevent the push block 24 from continuing to slide along the second direction.

[0060] In particular, in some embodiments, as Figures 2 to 4 shown, the engaging portion 241 is a strip structure, the length direction of the engaging portion 241 is consistent with the sliding direction of the engaging portion 241 relative to the switching piece 21, one end of one stop portion 242 is connected to one end of the engaging portion 241, and one end of the other stop portion 242 is connected to the other end of the engaging portion 241, forming a Z-shaped structure.

[0061] The two ends of the engaging portion 241 are a first end and a second end, respectively, and the first end is arranged downstream of the second end in the first direction. One end of one stop portion 242 is connected to the first end of the engaging portion 241, and the other end of the stop portion 242 extends in the reverse direction of the first direction. One end of the other stop portion 242 is connected to the second end of the engaging portion 241, and the other end of the stop portion 242 extends in the first direction.

[0062] In some embodiments, the surface of the stop portion 242 for abutting against the switching piece 21 is arranged in the first direction.

[0063] Further, in some embodiments, as Figures 2 to 4 shown, the first inclined surface 2421 is formed on one stop portion 242. As Figure 3 shown, when the push block 24 moves to the limit position along the second direction, the left side stop portion 242 abuts against the switching piece 21, and the right side stop portion 242 is arranged spaced apart from the switching piece 21. The normal vector of the first inclined surface 2421 can be decomposed into a sub-vector along the second direction and a sub-vector along the reverse direction of the first direction. Therefore, as Figure 4 shown, when the pressing piece 23 presses the first inclined surface 2421, the push block 24 can slide in the reverse direction of the second direction.

[0064] Alternatively, the push block 24 can also have other shapes, as long as it is slidably engaged with the switching piece 21 along the aforementioned sliding direction, and has a first inclined surface 2421 which is located in the pressing path of the pressing piece 23 when the switching piece 21 is located at the position of blocking the water flow passage.

[0065] For example, in some embodiments, the middle part of the anti-slip part 242 is connected to the mating part 241, or the anti-slip part 242 is a protrusion added to the mating part 241. When the mating part 241 slides to the limit position relative to the switching member 21, the protrusion can abut against the switching member 21 to limit its continued sliding.

[0066] Alternatively, the first inclined surface 2421 may also be formed at other locations of the push block 24, without specific restrictions here.

[0067] Furthermore, in some embodiments, such as Figure 2 As shown, the switching component 21 is provided with a guide groove 211, and the push block 24 is slidably engaged in the guide groove 211, so that the two can slide in the aforementioned sliding direction.

[0068] Specifically, such as Figures 2 to 4 As shown, the mating part 241 is slidably fitted in the guide groove 211, and the sidewall of the guide groove 211 is arranged along the direction in which the mating part 241 slides relative to the switching member 21. When the switching member 21 slides back and forth along the first direction, the sidewall of the guide groove 211 provides a thrust to the mating part 241, causing the push block 24 to slide back and forth along the second direction.

[0069] In some embodiments, the switching member 21 is a rod-shaped structure, and the sidewall arrangement direction of the guide groove 211 intersects the axial direction of the rod-shaped structure. When the switching member 21 slides along the first direction, the sidewall of the guide groove 211 pushes against the push block 24, and the push block 24 slides relative to the switching member 21 along the arrangement direction of the sidewall of the guide groove 211.

[0070] The guide groove 211 provided on the switching component 21 has a slot, such as Figures 2 to 4 As shown, the pusher block 24 can be directly pressed into the guide groove 211 from the slot, making installation convenient.

[0071] Optionally, the switching member 21 and the push block 24 can also be slidably engaged in other ways, such as by providing a through hole in the switching member 21, with part of the push block 24 inserted into the through hole, and the through hole's through direction being the sliding direction of the push block 24 relative to the switching member 21. Specifically, in one embodiment, the mating part 241 is inserted into the through hole.

[0072] Furthermore, such as Figures 5 to 13 As shown, in some embodiments, the water outlet switching mechanism further includes a decorative shell 25, which is assembled in the mechanism body 11. The decorative shell 25 has a first insertion hole 251. The switching member 21 is inserted into the first insertion hole 251 along the first direction. The switching member 21 fits against the hole wall of the first insertion hole 251, and the hole wall of the first insertion hole 251 covers the slot of the guide groove 211.

[0073] When assembling, the push block 24 can be assembled into the guide groove 211 first, and then the switching piece 21 with the push block 24 assembled is inserted into the first insertion hole 251. After the switching piece 21 is inserted into the first insertion hole 251, the hole wall of the first insertion hole 251 covers the slot of the guide groove 211, thereby limiting the push block 24 in the guide groove 211.

[0074] In some embodiments, as shown in Figure 1 , Figure 5 , Figure 8 and Figure 10 , the decorative shell 25 is fixed relative to the mechanism body 11 in the first direction. The switching piece 21 is slidable in the first insertion hole 251, and the guide groove 211 is located in the first insertion hole 251. As shown in Figure 12 and Figure 13 , the hole wall of the first insertion hole 251 is provided with a plurality of relief notches 252 arranged in the axial direction, and the push block 24 slides along the relief notches 252 when the switching piece 21 slides in the first insertion hole 251.

[0075] When the switching piece 21 slides back and forth relative to the mechanism body 11 in the first direction, the switching piece 21 is always inserted into and slides in the first insertion hole 251, and a part of the push block 24 extends out of the first insertion hole 251 from the relief notches 252. The push block 24 slides synchronously along the relief notches 252 when the switching piece 21 slides.

[0076] Further, in some embodiments, the part of the push block 24 provided with the first inclined surface 2421 is located outside the first insertion hole 251, and the part of the pressing piece 23 for pressing against the first inclined surface 2421 is located outside the first insertion hole 251.

[0077] As shown in Figure 12 and Figure 13 , in some embodiments, the decorative shell 25 further has a plurality of limiting lugs 253 arranged one-to-one with the relief notches 252. Each of the limiting lugs 253 has a pressing channel 254 arranged in the first direction, and the relief notches 252 communicate the pressing channels 254 with the first insertion hole 251. The part of the push block 24 provided with the first inclined surface 2421 is located in the pressing channel 254, the part of the pressing piece 23 for pressing against the first inclined surface 2421 is located in the pressing channel 254, and the part of the pressing piece 23 can slide in the pressing channel 254.

[0078] Specifically, as shown in Figures 5 to 11As shown, in one embodiment, each of the anti-skid portions 242 is located in a corresponding pressing channel 254, and the first inclined surface 2421 is formed on one of the anti-skid portions 242. When the pressing member 23 is pressed along the pressing channel 254, the first inclined surface 2421 is pressed.

[0079] Further, as shown, Figure 2 in some embodiments, the pressing member 23 comprises a pressing leg 231 and a protection leg 232, the pressing leg 231 is slidably inserted into one of the pressing channels 254, and the protection leg 232 is slidably inserted into another of the pressing channels 254. The pressing leg 231 is opposite to the first inclined surface 2421 in the same pressing channel 254. The protection leg 232 is located outside the anti-skid portion 242 in the pressing channel 254.

[0080] As shown, Figures 2 to 4 when the pressing member 23 is pressed, the protection leg 232 is protected by the anti-skid portion 242 in the same pressing channel 254. Here, the inside refers to the side of the protection leg 232 close to the switching member 21. The pressing channel 254 guides the pressing leg 231 and the protection leg 232.

[0081] In some embodiments, the surface of the pressing member 23 opposite to the first inclined surface 2421 is a matching inclined surface 2311, and the angle of the matching inclined surface 2311 is consistent with the angle of the first inclined surface 2421. Specifically, in one embodiment, as shown, Figures 5 to 11 the surface of the pressing leg 231 opposite to the first inclined surface 2421 is the matching inclined surface 2311 with the same angle as the first inclined surface 2421. When the pressing member 23 contacts the first inclined surface 2421, the first inclined surface 2421 and the matching inclined surface 2311 contact each other and slide relative to each other.

[0082] In some embodiments, as shown, Figures 1 to 4 the pressing member 23 can move back and forth within a predetermined range in the first direction relative to the mechanism body 11, and the elastic return member 22 is connected to or abuts against the pressing member 23, so that the mechanism body 11 indirectly limits the movement range of the elastic return member 22, and the elastic return member 22 can provide a force for the switching member 21 to slide in the first direction.

[0083] Specifically, in some embodiments, as shown, Figure 12 the pressing leg 231 and / or the protection leg 232 is provided with an anti-disengagement protrusion 233. As shown, Figure 13 and Figures 2 to 11As shown, the channel wall of the pressing channel 254 is provided with an anti-detachment protrusion 255. The anti-detachment protrusion 255 is located in the opposite direction of the anti-detachment protrusion 233 in the pressing direction, and the elastic reset member 22 acts directly between the pressing member 23 and the switching member 21.

[0084] The decorative shell 25 is fixed relative to the mechanism body 11 in the first direction. The anti-detachment protrusion 255 defines the movement limit of the anti-detachment protrusion 233 in the opposite direction of the pressing direction. Therefore, the pressing member 23 can provide support for the elastic reset member 22 so that the elastic reset member 22 can provide elastic force for the switching member 21.

[0085] The elastic reset member 22 can be a compression spring. One end of the elastic reset member 22 abuts against the pressing member 23, and the other end abuts against the switching member 21. The elastic force direction of the elastic reset member 22 is consistent with the first direction.

[0086] More specifically, such as Figure 1 As shown, in some embodiments, the pressing member 23 further includes a pressing cylinder 234, the pressing foot 231 and the protective foot 232 are both connected to the pressing cylinder 234, the opening of the pressing cylinder 234 faces the same direction as the pressing direction, the switching member 21 is arranged correspondingly to the pressing cylinder 234, the elastic reset member 22 abuts between the bottom wall of the pressing cylinder 234 and the switching member 21, the switching member 21 is provided with a positioning groove 212 at the position where it abuts the elastic reset member 22, and one end of the elastic reset member 22 is inserted into the positioning groove 212.

[0087] like Figure 5 , Figure 8 , Figure 10 and Figure 5 As shown, in some embodiments, the water outlet switching mechanism includes multiple switching units 20, the water flow channel includes a main water inlet channel and multiple water outlet channels, the switching unit 20 corresponds one-to-one with the water outlet channel, and the switching element 21 is used to control the connection and disconnection between the corresponding water outlet channel and the main water inlet channel.

[0088] When the water outlet switching mechanism includes multiple switching units 20, multiple first insertion holes 251 can be provided in the decorative shell 25, and the first insertion holes 251 correspond one-to-one with the switching component 21. The decorative shell 25 is provided with multiple limiting lugs 253, one pressing foot 231 corresponds to one limiting lug 253, and one protective foot 232 corresponds to one limiting lug 253.

[0089] In the water outlet device 10, one water outlet channel is a shower water channel 111, and another water outlet channel is a vibrating water channel 112. The water outlet device 10 has two water outlet functions. For example... Figure 8As shown, the switching pieces 21 in both switching units 20 are in positions to block the corresponding water flow channels, and the shower water channel 111 and the oscillation water channel 112 are both blocked from the total water inlet channel. Figure 10 As shown, the pressing piece 23 in the right switching unit 20 is pressed down, and the switching piece 21 in the switching unit 20 is in a position to open the water flow channel, and the shower water channel 111 is open to the total water inlet channel. Figure 5 As shown, the pressing piece 23 in the left switching unit 20 is pressed down, and the switching piece 21 in the switching unit 20 is in a position to open the water flow channel, and the oscillation water channel 112 is open to the total water inlet channel.

[0090] As shown in Figure 8 , Figure 10 and Figure 1 , in some embodiments, a plurality of switching units 20 are arranged along the radial direction of the water outlet channel in sequence. A decorative cover 26 is arranged on each pressing piece 23, and the cross section of the decorative cover 26 is semicircular. The decorative cover 26 covers the pressing piece 23 on the inside, improving the appearance.

[0091] Further, as shown in Figure 1 , in some embodiments of the present application, a water outlet device 10 is provided, which comprises a water outlet panel 12 and the water outlet switching mechanism described in any of the above embodiments. The mechanism body 11 is a spray gun body, the water outlet panel 12 has a plurality of water spraying holes, and the water outlet panel 12 is arranged at the water outlet of the water flow channel.

[0092] The water outlet device 10 adopts the water outlet switching mechanism described in any of the above embodiments, and has the effects of high reliability of component cooperation, compact arrangement, and compact overall structure. The water flowing in the water flow channel is sprayed out of each water spraying hole on the water outlet panel 12.

[0093] As shown in Figures 5 to 11 , Figure 1 , in some embodiments, the spray gun body comprises a holding cylinder 13, a spraying cylinder 14, and a water path switching unit 15. The axial direction of the holding cylinder 13 intersects the axial direction of the spraying cylinder 14, one end of the holding cylinder 13 is connected to the cylinder wall of the spraying cylinder 14, and the position of the spraying cylinder 14 where the holding cylinder 13 is connected is provided with a water passing through hole (not shown in the figure), so that the channel in the holding cylinder 13 is in communication with the channel in the spraying cylinder 14. The switching unit 20 and the water path switching unit 15 are both installed in the spraying cylinder 14, the water path switching unit 15 and the spraying cylinder 14 together form the water flow channel, and the limiting part 16 belongs to the water path switching unit 15.

[0094] Specifically, in some embodiments, as shown in Figure 5 , Figure 8 , Figure 10 andFigure 5 As shown, the waterway switching unit 15 comprises a sealing gasket 151, an upper sealing cover 152, a lower sealing cover 153 and a water distribution plate 154. The upper sealing cover 152 and the lower sealing cover 153 are fitted together, and the sealing gasket 151 is located at the fitting position of the upper sealing cover 152 and the lower sealing cover 153. The sealing gasket 151 is provided with a water inlet hole 1511, and the sealing gasket 151 is provided with a first pressure relief cavity 1521 between the sealing gasket 151 and the upper sealing cover 152. The sealing gasket 151 is provided with a second pressure relief cavity 1531 between the sealing gasket 151 and the lower sealing cover 153. The water inlet hole 1511 is communicated with the first pressure relief cavity 1521 and the second pressure relief cavity 1531. The first pressure relief cavity 1521 and the second pressure relief cavity 1531 are respectively located on both sides of the sealing gasket 151. The second pressure relief cavity 1531 is communicated with the water passing through hole. The lower sealing cover 153 is further provided with a water outlet hole 1532. The sealing gasket 151 is movably arranged at the water outlet hole 1532. The water outlet hole 1532 and the second pressure relief cavity 1531 share a side wall, which is a shared side wall. When a gap appears between the sealing gasket 151 and the shared side wall, the second pressure relief cavity 1531 is communicated with the water outlet hole 1532 through the gap. The sealing gasket 151 is provided with a switch hole 1512 at a position corresponding to the water outlet hole 1532. The switching piece 21 is used to block and open the switch hole 1512. When the switch hole 1512 is in an open and conductive state, the first pressure relief cavity 1521 is communicated with the water outlet hole 1532 through the switch hole 1512. The water distribution plate 154 is located downstream of the lower sealing cover 153 and is used to distribute the water flowing out of the water outlet hole 1532 into different downstream channels. The water flowing through the water distribution plate 154 is finally directed to the water outlet panel 12.

[0095] The pipe is communicated with one end of the holding cylinder 13 away from the spraying cylinder 14. The water in the pipe first enters the holding cylinder 13 and then enters the water flow channel from the water passing through hole. Figure 6 As shown, when the switching pieces 21 in the two switching units 20 are all in positions of blocking the corresponding water flow channels, at this time, the sealing gasket 151 abuts against the shared side wall. The switch hole 1512 on the sealing gasket 151 is blocked by the corresponding switching piece 21. The first pressure relief cavity 1521 and the second pressure relief cavity 1531 are both in a cut-off state with the water outlet hole 1532. The water entering the spraying cylinder 14 is intercepted in the first pressure relief cavity 1521 and the second pressure relief cavity 1531. The water pressure difference on both sides of the sealing gasket 151 is small. Figure 7 Figure 8 As shown, the two push blocks 24 are both slid to the limit position relative to the limiting part 16 in the second direction. The first inclined surface 2421 of the two push blocks 24 is located in the pressing direction of the corresponding pressing piece 23.

[0096] As shown, Figure 9 Figure 8 ​​As shown, after the presser 23 corresponding to the shower water passage 111 is pressed down, the push block 24 corresponding to the presser 23 is extruded to slide in the reverse direction of the second direction relative to the limiting portion 16, the switching piece 21 slides in the reverse direction of the first direction against the elastic force of the elastic reset piece 22, and the switching piece 21 is separated from the switch hole 1512. As shown in the initial stage of the reverse sliding of the switching piece 21 in the first direction, the switching piece 21 is separated from the switch hole 1512, and the switching piece 21 is in the first state. Figure 10 As shown, the first pressure relief cavity 1521 communicates with the water outlet hole 1532 through the switch hole 1512, and the water in the first pressure relief cavity 1521 can flow downstream from the switch hole 1512 and the water outlet hole 1532 and finally be sprayed from the water outlet panel 12. As the amount of water in the first pressure relief cavity 1521 decreases, the pressure difference on both sides of the sealing gasket 151 increases, the sealing gasket 151 floats up, a gap appears between the sealing gasket 151 and the common side wall, and the water in the second pressure relief cavity 1531 directly enters the water outlet hole 1532 from the gap, so that the shower water passage 111 is completely communicated with the total water inlet passage.

[0097] Similarly, as shown in Figure 11 and ​ When the presser 23 corresponding to the oscillation water passage 112 is pressed down, the push block 24 corresponding to the presser 23 is extruded to slide in the reverse direction of the second direction relative to the limiting portion 16, the switching piece 21 slides in the reverse direction of the first direction against the elastic force of the elastic reset piece 22, and the switching piece 21 is separated from the switch hole 1512. After the amount of water in the first pressure relief cavity 1521 decreases in the initial stage, a gap appears between the sealing gasket 151 and the common side wall, and the water in the second pressure relief cavity 1531 directly enters the water outlet hole 1532 from the gap, so that the oscillation water passage 112 is completely communicated with the total water inlet passage.
