[0070] Embodiment 1

[0071] Figure 1The following is a schematic diagram of the exploded view of the shower head provided by the embodiment of the present invention. Figure 1 The present embodiment provides a water outlet device and a shower head. The shower head includes the water outlet device provided in the present embodiment.

[0072] Specifically, the shower head includes a shower housing 10, a water outlet device and a surface cover 50. The water outlet device includes a water inlet mechanism 20, a water diversion body 30, a water diversion seat 40 and a water outlet surface cover 60. The shower housing 10 and the surface cover 50 enclose an installation space, and the water diversion body 30 and the water diversion seat 40 are accommodated in the installation space. The water diversion body 30 is provided with a plurality of water outlet cavities 13 corresponding to a plurality of water outlet effects, and the water inlet mechanism 20 is arranged at the top of the shower housing 10 to connect to a water source. The water diversion seat 40 is arranged below the water diversion body 30 and is provided with a plurality of water outlet holes for water outlet. The water outlet surface cover 60 is arranged below the water diversion seat 40 away from the water diversion body 30, and is provided with a plurality of water outlet nozzles for water outlet, and the number of the water outlet nozzles is greater than the number of water outlet holes on the water diversion seat 40.

[0073] Specifically, the water inlet mechanism 20 includes a water inlet nut 21, a water inlet ball head 22 and a water inlet seat 23. The water inlet seat 23 is arranged at the top of the shower housing 10, the water inlet nut 21 is screwed to the water inlet seat 23, the water inlet ball head 22 is arranged between the water inlet nut 21 and the water inlet seat 23, the water inlet nut 21 and the water inlet seat 23 can compress the water inlet ball head 22, and the water inlet ball head 22 can be threadedly connected to the water inlet pipe (not shown in the figure). The water inlet ball head 22 is movably embedded in the top of the water inlet seat 23, so as to adjust the relative angle between the shower housing 10 and the water inlet nut 21, that is, to adjust the water outlet angle of the shower head.

[0074] Figure 2 A partial structural schematic diagram of a water diversion body provided by an embodiment of the present invention is shown (from an upward perspective); Figure 3 A partial structural schematic diagram of a water diversion body provided by an embodiment of the present invention is shown (from a top view); Figure 5 A bottom view of a shower head provided by an embodiment of the present invention is shown; Fig.10 Show Figure 5 Sectional view along CC direction; Fig.11 Show Fig.10 A partial enlarged view of the structure marked with G. Figure 2-Figure 5 , Fig.10 and Fig.11 In this embodiment, the water outlet device is formed with multiple pressure chambers 1 corresponding to multiple water outlet effects. The water outlet device provided in this embodiment includes a waterway switching mechanism 110, a water diversion mechanism, an instantaneous switching mechanism 200, and a delayed switching mechanism 300. In this embodiment, the waterway switching mechanism 110 is specifically a ratchet, which can be moved to drive the water diversion mechanism to move, so as to selectively open the water outlet of the corresponding pressure chamber 1.

[0075] Specifically, the water outlet device includes a switching space and a water diversion space. The waterway between the switching space and the water diversion space is not connected, the waterway switching mechanism 110 is arranged in the switching space, and the water diversion mechanism is arranged in the water diversion space.

[0076] Specifically, the instantaneous switching mechanism 200 and the delayed switching mechanism 300 can respectively drive the water circuit switching mechanism 110 to perform opposite actions. After the water outlet device in the boiling water state turns off the water, it does not turn on the water again or turns on the water after a period of time. The instantaneous switching mechanism 200 and the delayed switching mechanism 300 successively drive the water circuit switching mechanism 110 so that the water circuit switching mechanism 110 and the water diversion mechanism maintain the state before the water is turned off. The period of time here can be 5 seconds, 10 seconds or other time, which can be designed according to market demand. After the water outlet device in the boiling water state turns off the water, it quickly turns on the water. The instantaneous switching mechanism 200 drives the water circuit switching mechanism 110 to drive the water diversion mechanism to switch the water outlet effect. Through the action of the above-mentioned water diversion mechanism, the water outlet of the pressure chamber 1 can be selected to control the water outlet to achieve different water outlet effects. Through the instantaneous switching mechanism 200, the cyclic switching of the water outlet effect can be achieved when the water outlet device continuously and quickly turns on and off the water. Through the cooperation of the delayed switching mechanism 300 and the instantaneous switching mechanism 200, when the water outlet device is turned off for a long time and then turned on again, the water outlet effect before the water outlet is turned off can be maintained, which provides convenience for users in the use scenario where the user intermittently uses the same water outlet effect for a long period of time. When the water outlet device is flowing, the delayed switching mechanism 300 and the instantaneous switching mechanism 200 are away from the water channel switching mechanism 110, and when the water outlet device is turned off, the delayed switching mechanism 300 and the instantaneous switching mechanism 200 are close to the water channel switching mechanism 110 to realize the rotation action of the water channel switching mechanism 110.

[0077] Fig.12 Show Figure 5 Cross-sectional view along the DD direction; Fig.13 Show Fig.12 A partial enlarged view of the structure marked as H; Fig.14 Show Fig.12 A partial enlarged view of the structure marked as I. Figure 12-14 The water diversion mechanism includes a plurality of water diversion valve assemblies. The water diversion valve assembly includes a functional valve shaft 120, and the functional valve shaft 120 corresponds to the pressure chamber 1. The water channel switching mechanism 110 rotates to selectively drive the functional valve shaft 120 to open the corresponding water outlet of the pressure chamber 1.

[0078] Specifically, in this embodiment, the water diversion valve assembly is specifically arranged on the water diversion body 30, and also includes a functional valve body 150 and a sealing ring 160. The water diversion body 30 is provided with an installation groove 31, such as Figure 3As shown, the water diversion valve assembly is arranged in the installation groove 31, and the functional valve shaft 120 coaxially and movably penetrates the functional valve body 150, as shown in FIG. Figure 12-14 The sealing ring 160 is disposed around the functional valve shaft 120. When the functional valve shaft 120 moves along the axial direction of the functional valve body 150 in a direction away from the waterway switching mechanism 110, the sealing ring 160 can abut against the side wall of the functional valve body 150, thereby blocking the pressure relief channel 11. Fig.13 When the functional valve shaft 120 moves along the axial direction of the functional valve body 150 toward the direction close to the waterway switching mechanism 110, the sealing ring 160 can be separated from the side wall of the functional valve body 150, thereby opening the pressure relief channel 11, as shown Fig.14 shown.

[0079] Fig.15 Schematic diagram of the waterway switching mechanism mentioned in the first embodiment of the present invention is shown. More specifically, the water diversion valve assembly also includes a movable ball 130. The movable ball 130 corresponds to the functional valve shaft 120 one by one, and is arranged between one end of the functional valve shaft 120 and the waterway switching mechanism 110. The other end of the functional valve shaft 120 is provided with a functional valve shaft elastic element 140, and the waterway switching mechanism 110 is provided with a plurality of control notches 113 along the circumferential direction, such as Fig.15 As shown, when the water circuit switching mechanism 110 rotates to any control slot 113 facing the movable ball 130, the movable ball 130 can move into the control slot 113 under the action of the functional valve shaft elastic element 140, and the functional valve shaft 120 can move close to the water circuit switching mechanism 110 under the action of the functional valve shaft elastic element 140 to open the water outlet of the corresponding pressure chamber 1, as shown in FIG. Fig.14 shown.

[0080] Continue to refer to Figure 1 , Fig.10 and Fig.11 The water distribution mechanism also includes a plurality of pilot valves 400. The pilot valves 400 correspond to the pressure chamber 1 one by one, and the pilot valve 400 includes a pilot valve body 410. The pilot valve body 410 is provided with an annular gap 411. When the shower head sprays water, the water of the water inlet mechanism 20 can first enter the water inlet channel, and then enter the corresponding pressure chamber 1 through the annular gaps 411 of the plurality of pilot valves 400. Since the water inflow of the annular gap 411 is less than the water outflow of the pressure relief channel 11, the movement stroke of the functional valve shaft 120 will be relatively short, and the switching stroke of the functional valve shaft 120 can be shortened.

[0081] Reference Fig.13 and Fig.14The functional valve shaft 120 can control the connection and disconnection between the pressure relief channel 11 and the pressure chamber 1. The water channel switching mechanism 110 rotates to drive the functional valve shaft 120 to realize the connection and disconnection of the pressure relief channel 11, thereby controlling whether the pressure chamber 1 on the pilot valve body 410 is depressurized. When the pressure chamber 1 is depressurized, the pilot valve main channel is opened, and the water in the pilot valve main channel and the pressure relief channel 11 are combined in the downstream water outlet chamber 13.

[0082] Specifically, the pilot valve 400 further includes an opening and closing elastic element 420, which is coaxial with the pilot valve body 410 and is disposed against each other, and is specifically disposed above the pilot valve body 410. When the water in the pressure chamber 1 flows out through the corresponding pressure relief channel 11 for pressure relief, the opening and closing elastic element 420 is compressed under the action of the water pressure, and at this time, the water in the pilot valve main flow channel corresponding to the pressure chamber 1 and the pressure relief channel 11 are combined and discharged downstream.

[0083] More specifically, the opening and closing elastic element 420 is provided with a dredging rod 421, which can extend into the annular gap 411. When the pilot valve body 410 moves under the action of the water pressure change in the pressure chamber 1, the dredging rod 421 can be extended and retracted in the annular gap 411. Through the dredging rod 421, scale or impurities in the annular gap 411 can be cleared during each compression and recovery process of the opening and closing elastic element 420, so as to prevent the annular gap 411 from being blocked.

[0084] Figure 6 Show Figure 5 Sectional view along AA direction, Figure 8 Show Figure 5 Cross-sectional view along the BB axis. Figure 1 , Figure 3 , Figure 6 and Figure 8 , the instantaneous switching mechanism 200 and the delayed switching mechanism 300 can respectively push the water circuit switching mechanism 110 to rotate in different directions. After the shower head in the on-water state is turned off for a period of time, the instantaneous switching mechanism 200 and the delayed switching mechanism 300 successively push the water circuit switching mechanism 110 to rotate, so that the water circuit switching mechanism 110 maintains the state before the water is turned off. It should be noted that after the instantaneous switching valve shaft 220 completes the driving of the water circuit switching mechanism 110, it can move away from the water circuit switching mechanism 110 and separate from the first annular ratchet 111, so that the delayed switching valve shaft 320 can drive the water circuit switching mechanism 110 later. After the shower head in the on-water state is turned off, the water is quickly turned on, and the instantaneous switching mechanism 200 pushes the water circuit switching mechanism 110 to rotate and switch the water effect.

[0085] Specifically, the waterway switching mechanism 110 is provided with a first annular ratchet 111 and a second annular ratchet 112. Fig.15 As shown. The ratchet direction of the first annular ratchet 111 is opposite to the ratchet direction of the second annular ratchet 112. The instantaneous switching mechanism 200 and the delayed switching mechanism 300 are arranged opposite to each other, and the waterway switching mechanism 110 is arranged between the instantaneous switching mechanism 200 and the delayed switching mechanism 300. The instantaneous switching mechanism 200 can be matched and abutted against the first annular ratchet 111, and the delayed switching mechanism 300 can be matched and abutted against the second annular ratchet 112.

[0086] More specifically, the instantaneous switching mechanism 200 includes an instantaneous switching valve body 210, an instantaneous switching valve shaft 220, an instantaneous switching elastic element 230 and a first spring seat 260. A first control chamber 211 is formed inside the instantaneous switching valve body 210, and the first control chamber 211 is connected to the water inlet mechanism 20 of the shower head. The water inlet of the water inlet mechanism 20 can enter the first control chamber 211 to increase the pressure of the first control chamber 211. The first spring seat 260 is fixedly arranged on the water diversion seat 40, and one end of the instantaneous switching elastic element 230 abuts against the first spring seat 260. The instantaneous switching valve shaft 220 passes through the first control chamber 211, one end of which extends toward the water circuit switching mechanism 110, and the other end of which is provided with the instantaneous switching elastic element 230, and one end of the instantaneous switching elastic element 230 away from the water circuit switching mechanism 110 abuts against the first spring seat 260.

[0087] Reference Figure 6 After water flows through the water outlet device, the instantaneous switching valve shaft 220 is affected by the first area difference between the first sealing ring 212 between it and the instantaneous switching valve body 210 and the sealing ring arranged on its own peripheral side. When there is water in the first control chamber 211, and the product of the pressure in the first control chamber 211 and the first area difference is greater than the elastic force of the instantaneous switching elastic element 230, the instantaneous switching valve shaft 220 moves away from the water path switching mechanism 110.

[0088] It should be noted that when the instantaneous switching valve shaft 220 is away from the water channel switching mechanism 110 , the water inlet of the water inlet mechanism 20 can enter the corresponding pressure chamber 1 through the annular gaps 411 of the plurality of pilot valves 400 .

[0089] More specifically, the time-delay switching mechanism 300 includes a time-delay switching valve body 310, a time-delay switching valve shaft 320, a time-delay switching elastic element 330 and a second spring seat 360. A second control chamber 311 is formed inside the time-delay switching valve body 310, and the second control chamber 311 is connected to the water inlet mechanism 20 of the shower head. The water inlet of the water inlet mechanism 20 can enter the second control chamber 311 to increase the pressure of the second control chamber 311. The time-delay switching valve shaft 320 passes through the second control chamber 311, one end of which extends toward the water circuit switching mechanism 110, and the other end of which is provided with the time-delay switching elastic element 330. The second spring seat 360 is fixedly provided on the water diversion seat 40, and one end of the time-delay switching elastic element 330 away from the water circuit switching mechanism 110 abuts against the second spring seat 360.

[0090] Continue to refer to Figure 6 After water flows through the water outlet device, the delayed switching valve shaft 320 is affected by the second area difference between the second sealing ring 312 between it and the delayed switching valve body 310 and the sealing ring arranged on its own side. When there is water in the second control chamber 311, and the product of the pressure in the second control chamber 311 and the second area difference is greater than the elastic force of the delayed switching elastic element 330, the delayed switching valve shaft 320 moves away from the water path switching mechanism 110.

[0091] Figure 4 yes Figure 3 The enlarged view of the structure marked with J in FIG. Figure 3 and Figure 4 , the instantaneous switching mechanism 200 also includes a plurality of first guide posts 250. The plurality of first guide posts 250 are arranged at intervals, and the instantaneous switching valve shaft 220 is located between the plurality of first guide posts 250, and the first guide posts 250 can provide guidance for the movement of the instantaneous switching valve shaft 220. The first protrusion 221 and the second protrusion 222 are respectively arranged on opposite sides of the instantaneous switching valve shaft 220, the first protrusion 221 corresponds to one first guide post 250, and the second protrusion 222 corresponds to another first guide post 250. When the water outlet device turns off the water, the first protrusion 221 acts on the corresponding first guide post 250, so that the head of the instantaneous switching valve shaft 220 abuts against the first annular ratchet 111, and drives the waterway switching mechanism 110 to rotate through a certain angle. Then the second protrusion 222 acts on the corresponding first guide column 250 to make the head of the instantaneous switching valve shaft 220 disengage from the first annular ratchet 111 , and only then can the delayed switching valve shaft 320 act on the waterway switching mechanism 110 later.

[0092] Similarly, the time-delay switching mechanism 300 further includes a second guide column 350 , which can provide guidance for the movement of the time-delay switching valve shaft 320 .

[0093] That is to say, the first guide column 250 and the second guide column 350 can respectively ensure the stability and accuracy of the instantaneous switching valve shaft 220 and the delayed switching valve shaft 320 during operation.

[0094] Figure 7 Show Figure 6 A partial enlarged view of the structure marked as E; Fig. 9 Show Figure 8 A partial enlarged view of the structure marked with F. Figure 2 and Figure 6-Figure 9 The first control chamber 211 is connected to an instantaneous drain valve 240, through which the first control chamber 211 drains water at a very fast speed. After the water is turned off, the instantaneous switching valve shaft 220 approaches and pushes the waterway switching mechanism 110 to rotate under the action of the instantaneous switching elastic element 230. The second control chamber 311 is connected to a delayed drain valve 340, through which the second control chamber 311 drains water at a slower speed. The delayed switching valve shaft 320 can approach and push the waterway switching mechanism 110 to rotate under the action of the delayed switching elastic element 330. The drainage speed of the instantaneous drain valve 240 is greater than the drainage speed of the delayed drain valve 340.

[0095] Specifically, Figure 7 As shown, the delayed drain valve 340 drains water through the drain gap 341, as shown in FIG. Fig. 9 As shown, the instantaneous drain valve 240 drains water through the drain channel 241. The inner diameter of the drain channel 241 is much larger than the inner diameter of the drain gap 341, so the drainage speed of the drain channel 241 is greater than the drainage speed of the drain gap 341. When the shower head is turned on and then turned off, the delayed switching valve shaft 320 and the instantaneous switching valve shaft 220 will reset close to the water path switching mechanism 110, and their reset speeds are related to the drainage speeds of the delayed drain valve 340 and the instantaneous drain valve 240, respectively. Since the drainage speed of the delayed drain valve 340 is much smaller than the drainage speed of the instantaneous drain valve 240, the instantaneous switching valve shaft 220 can reset faster, that is, when the water is turned on and off continuously and quickly, the water path switching mechanism 110 can be continuously controlled by the instantaneous switching valve shaft 220 and then rotated, thereby continuously switching the water discharge effect. When the shower head in the open water state is turned off for a long time, the delayed drain valve 340 realizes drainage, and the delayed switching valve shaft 320 will be reset under the action of the delayed switching elastic element 330. After the water path switching mechanism 110 is driven by the instantaneous switching valve shaft 220 to rotate clockwise by a certain angle, it is driven by the delayed switching valve shaft 320 to rotate counterclockwise by the same angle, so that the water path switching mechanism 110 remains in the state before the water is turned off, that is, the water outlet effect before the water is turned off is maintained.

[0096] This embodiment also provides a water channel switching method, which implements the switching of water outlet effects based on the water outlet device provided in this embodiment. The water channel switching method specifically includes the following steps:

[0097] Step S1, turning on the shower head and letting water in through the water inlet mechanism 20;

[0098] Step S2, the instantaneous switching mechanism 200 and the delayed switching mechanism 300 can be away from the water channel switching mechanism 110 when water is flowing into the water outlet device, and water flows into the pressure chamber 1. At this time, the water channel switching mechanism 110 selectively controls one pressure chamber 1 to discharge water, thereby achieving a water outlet effect;

[0099] Step S3, the water outlet device in the boiling water state turns off the water, the instantaneous switching mechanism 200 and the delayed switching mechanism 300 successively drive the water circuit switching mechanism 110, so that the water circuit switching mechanism 110 rotates in two opposite directions at the same angle successively to maintain the state before the water is turned off, so that the water outlet state before the water is turned off can be maintained when the water is turned on next time.

[0100] The water outlet device in the boiling water state turns off the water and then quickly turns on the water again. At this time, the delayed switching mechanism 300 is still separated from the water circuit switching mechanism 110 and cannot control the water circuit switching mechanism 110. At this time, only the instantaneous switching mechanism 200 drives the water circuit switching mechanism 110 to rotate a certain angle, and the water circuit switching mechanism 110 is actuated to control the water discharge of the other pressure chamber 1, thereby realizing the switching of the water outlet effect.

[0101] Embodiment 2

[0102] This embodiment provides a water outlet device, and the difference between this embodiment and the first embodiment is only in the specific water distribution method of the water distribution mechanism.

Figure 1 ; Fig.16 A partial structural cross-section of a shower head provided in the second embodiment of the present invention is shown. Figure 2 . Reference Fig.15 and Fig.16The water outlet device provided in this embodiment is not provided with the pressure chamber 1 in the first embodiment, and the water inlet mechanism 20 is directly connected to the water flow channel 14. The water flow channel 14 corresponds to a plurality of water outlets 12, and the plurality of water outlets 12 correspond one by one to a plurality of water outlet chambers 13. Different water outlet chambers 13 correspond to different water outlet effects. The water channel switching mechanism 110 rotates to drive the water diversion mechanism to operate. In this embodiment, there are two water outlets 12 corresponding to the water flow channel 14. The two water outlets 12 are spaced apart in the axial direction of the functional valve shaft 120. Through the movement of the water diversion mechanism along this straight line, the two water outlets 12 can be alternately opened, thereby realizing the switching of the water outlet effect.

[0104] Specifically, the water diversion mechanism includes a water diversion valve assembly. The structure of the water diversion valve assembly can be the same as that in the first embodiment. The functional valve shaft 120 is arranged in the water diversion space. The water channel switching mechanism 110 rotates to drive the functional valve shaft 120 to perform a linear motion along its axial direction. Fig.15 and Fig.16 The two positions are switched to alternately open the water outlet 12 of the water flow channel 14 to achieve switching of the water outlet effect.
