Description

Technical Field

[0001] This utility model relates to the field of bathroom fixtures technology, and in particular to a water outlet device and a shower head. Background Technology

[0002] A top-mounted shower head is a water jet installed on the ceiling. The design of a top-mounted shower head is mainly to enrich the shower experience by providing a large area of ​​water coverage, so that users can feel a rain-like effect when showering.

[0003] Existing overhead showerheads can switch water flow effects, with the main process being as follows: the water path automatically switches between different effects the instant the water is turned off and on. However, after the water is turned off for a period of time, these overhead showerheads automatically reset and switch back to the initial water flow effect, failing to maintain the effect before the water was turned off. This can be inconvenient for users who intermittently use the same water flow effect over a relatively long period.

[0004] Therefore, there is an urgent need for a water outlet device and a shower head overhead spray to solve the above problems. Utility Model Content

[0005] According to one aspect of this utility model, the objective is to provide a water outlet device that can switch the water outlet effect when the shower head is quickly turned on and off, and maintain the water outlet effect before the water was turned off when the water is turned off and then turned on again after a long period of time. This provides convenience for users in scenarios where they use the same water outlet effect intermittently over a relatively long period of time.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A water outlet device, comprising:

[0008] Waterway switching mechanism;

[0009] The water distribution mechanism, wherein the water path switching mechanism is capable of actuating to drive the water distribution mechanism to actuate;

[0010] The instantaneous switching mechanism and the delayed switching mechanism are respectively capable of driving the waterway switching mechanism to perform opposite actions;

[0011] After the water outlet device, which is in the hot water state, shuts off the water for a period of time, the instantaneous switching mechanism and the delayed switching mechanism sequentially drive the water circuit switching mechanism to keep the water circuit switching mechanism and the water distribution mechanism in the state before shutting off the water.

[0012] When the water outlet device is in the hot water state, it turns off the water and then quickly turns it back on. The instantaneous switching mechanism drives the water path switching mechanism to operate, thereby driving the water distribution mechanism to switch the water outlet effect.

[0013] As a preferred embodiment of the water outlet device provided by this utility model, the water outlet device includes multiple water outlets. The rotation of the water path switching mechanism can drive the water distribution mechanism to operate, so as to selectively open the corresponding water outlet. The instantaneous switching mechanism and the delayed switching mechanism can respectively push the water path switching mechanism to rotate in different directions.

[0014] After the water outlet device, which is in the hot water state, shuts off the water for a period of time, the instantaneous switching mechanism pushes the water circuit switching mechanism to rotate and move away from the water circuit switching mechanism. Then, the delayed switching mechanism pushes the water circuit switching mechanism to rotate, so that the water circuit switching mechanism and the water distribution mechanism remain in the state before the water is shut off.

[0015] When the water outlet device is in the hot water state, it turns the water on quickly after the water is turned off. The instantaneous switching mechanism pushes the water path switching mechanism to rotate, thereby driving the water distribution mechanism to switch the water outlet effect.

[0016] As a preferred embodiment of the water outlet device provided by this utility model, it includes a switching space and a water distribution space, wherein the water path between the switching space and the water distribution space is not connected, the water path switching mechanism is disposed in the switching space, and the water distribution mechanism is disposed in the water distribution space.

[0017] As a preferred embodiment of the water outlet device provided by this utility model, the water outlet device includes multiple pressure chambers, multiple water distribution spaces, and multiple water distribution mechanisms including multiple functional valve shafts. The multiple functional valve shafts are respectively located in the multiple water distribution spaces and correspond one-to-one with the multiple pressure chambers. When the water circuit switching mechanism rotates, it can selectively drive one of the functional valve shafts to move, so that the water in the corresponding pressure chamber flows into the water outlet chamber through the water outlet.

[0018] As a preferred embodiment of the water outlet device provided by this utility model, the water path switching mechanism is provided with a first circumferential ratchet and a second circumferential ratchet, the ratchet direction of the first circumferential ratchet and the ratchet direction of the second circumferential ratchet are opposite; the instantaneous switching mechanism and the delayed switching mechanism are arranged opposite to each other, the water path switching mechanism is arranged between the instantaneous switching mechanism and the delayed switching mechanism, the instantaneous switching mechanism can cooperate to abut against the first circumferential ratchet, and the delayed switching mechanism can cooperate to abut against the second circumferential ratchet.

[0020] The instantaneous switching valve shaft passes through the first control chamber, with one end extending toward the water circuit switching mechanism and the other end provided with the instantaneous switching elastic element. When the pressure in the first control chamber increases to a level greater than the elastic force of the instantaneous switching elastic element, the instantaneous switching valve shaft moves away from the water circuit switching mechanism; and / or,

[0021] The delay switching mechanism includes a delay switching valve body, a delay switching valve shaft, and a delay switching elastic element. A second control chamber is formed inside the delay switching valve body. The second control chamber is connected to the water inlet mechanism of the shower head. Water from the water inlet mechanism can enter the second control chamber to increase the pressure in the second control chamber.

[0022] The delay switching valve shaft passes through the second control chamber, with one end extending toward the water circuit switching mechanism and the other end provided with the delay switching elastic element. When the pressure in the second control chamber increases to a level greater than the elastic force of the delay switching elastic element, the delay switching valve shaft moves away from the water circuit switching mechanism.

[0023] As a preferred embodiment of the water outlet device provided by this utility model, the first control chamber is connected to an instantaneous drain valve, and the first control chamber drains water through the instantaneous drain valve;

[0024] The second control chamber is connected to a delayed drain valve, through which the second control chamber drains water;

[0025] The drainage speed of the instantaneous drain valve is greater than that of the delayed drain valve.

[0026] As a preferred embodiment of the water outlet device provided by this utility model, the water outlet device further includes multiple pilot valves, each corresponding to one of the pressure chambers. Each pilot valve includes a pilot valve body with an annular gap. When the instantaneous switching valve shaft moves away from the water circuit switching mechanism, the water inlet of the shower head spray mechanism can enter the corresponding pressure chamber through the annular gap of the multiple pilot valves.

[0027] As a preferred embodiment of the water outlet device provided by this utility model, the water distribution mechanism further includes a movable ball, which corresponds one-to-one with the functional valve shaft and is disposed between one end of the functional valve shaft and the water circuit switching mechanism. The other end of the functional valve shaft is provided with a functional valve shaft elastic element. The water circuit switching mechanism is provided with a plurality of control slots along the circumference. When the water circuit switching mechanism rotates to any of the control slots facing the movable ball, the movable ball moves into the control slot, and the functional valve shaft can move under the action of the functional valve shaft elastic element to open the outlet of the corresponding pressure chamber.

[0028] As a preferred embodiment of the water outlet device provided by this utility model, the water distribution space has multiple water outlets, and a functional valve shaft is provided in the water distribution space. The multiple water outlets are distributed at intervals along the axial direction of the functional valve shaft. The multiple water outlets are opened alternately by moving the functional valve shaft along its axial direction.

[0029] According to another aspect of the present invention, the object is to provide a shower head top spray, including a shower head housing and a face cover, and further including a water outlet device as described in any of the above embodiments.

The water path switching mechanism can actuate to drive the water distribution mechanism. Through the action of the water path switching mechanism, the water distribution mechanism can be driven to actuate, thereby switching the water outlet effect. The instantaneous switching mechanism and the delayed switching mechanism can respectively drive the water path switching mechanism to perform opposite actions. When the water outlet device is in the hot water state and then the water is turned off for a period of time, the instantaneous switching mechanism and the delayed switching mechanism sequentially drive the water path switching mechanism to maintain the water path switching mechanism and the water distribution mechanism in the state before the water was turned off. When the water outlet device is in the hot water state and then the water is quickly turned on again, the instantaneous switching mechanism drives the water path switching mechanism to actuate, thereby driving the water distribution mechanism to actuate and switch the water outlet effect. In other words, this water outlet device can achieve cyclical switching of the water outlet effect when the shower head is continuously and rapidly switched on and off, and maintains the water outlet effect before the water was turned off when the water is turned off and then on again after a long period of time. This provides convenience for users in scenarios where they intermittently use the same water outlet effect over a relatively long period of time. Attached Figure Description

[0065] Example 1

[0066] Figure 1 An exploded view of the overhead shower provided in Embodiment 1 of this utility model is shown. (Refer to...) Figure 1 This embodiment provides a water outlet device and a shower head overhead spray. The shower head overhead spray includes the water outlet device provided in this embodiment.

[0067] Specifically, the overhead shower includes a shower housing 10, a water outlet device, and a faceplate 50. The water outlet device includes a water inlet mechanism 20, a water distribution body 30, a water distribution base 40, and a water outlet faceplate 60. The shower housing 10 and faceplate 50 form an installation space, within which the water distribution body 30 and water distribution base 40 are housed. The water distribution body 30 has multiple water outlet chambers 13 corresponding to the multiple water outlet effects. The water inlet mechanism 20 is located on top of the shower housing 10 to connect to a water source. The water distribution base 40 is located below the water distribution body 30 and has multiple water outlet holes for water outlet. The water outlet faceplate 60 is located below the water distribution base 40, away from the water distribution body 30, and has multiple water nozzles for water outlet; the number of water nozzles is greater than the number of water outlet holes on the water distribution base 40.

[0068] More specifically, the water inlet mechanism 20 includes an inlet nut 21, an inlet ball head 22, and an inlet seat 23. The inlet seat 23 is located on the top of the shower head housing 10, the inlet nut 21 is screwed onto the inlet seat 23, and the inlet ball head 22 is disposed within the inlet nut 21 and the inlet seat 23. The inlet nut 21 and the inlet seat 23 can press the inlet ball head 22 tightly, and the inlet ball head 22 can be threaded onto the inlet pipe (not shown in the figure). The inlet ball head 22 is movably embedded in the top of the inlet seat 23, facilitating the adjustment of the relative angle between the shower head housing 10 and the inlet nut 21, i.e., adjusting the water outlet angle of the shower head's overhead spray.

[0069] Figure 2 A partial structural schematic diagram (from below) of the water distribution body provided in Embodiment 1 of this utility model is shown. Figure 3 A partial structural schematic diagram (top view) of the water distribution body provided in Embodiment 1 of this utility model is shown. Figure 5 This is a bottom view of the overhead shower provided in Embodiment 1 of this utility model; Figure 10 Show Figure 5 A cross-sectional view along the CC direction; Figure 11 Show Figure 10 A magnified view of the structure labeled G in the middle. (Refer to...) Figures 2-5 , Figure 10 and Figure 11 In this embodiment, the water outlet device has multiple pressure chambers 1 corresponding to multiple water outlet effects. The water outlet device provided in this embodiment includes a water path switching mechanism 110, a water distribution mechanism, an instantaneous switching mechanism 200, and a delayed switching mechanism 300. In this embodiment, the water path switching mechanism 110 is specifically a ratchet, which can be activated to drive the water distribution mechanism to selectively open the outlet of the corresponding pressure chamber 1.

[0070] Specifically, the water outlet device includes a switching space and a water distribution space. The water path between the switching space and the water distribution space is not connected. The water path switching mechanism 110 is disposed in the switching space, and the water distribution mechanism is disposed in the water distribution space.

[0071] Specifically, the instantaneous switching mechanism 200 and the delayed switching mechanism 300 can respectively drive the water path switching mechanism 110 to perform opposite actions. When the water outlet device in the hot water state shuts off and then doesn't turn on again, or waits a certain period before turning on again, the instantaneous switching mechanism 200 and the delayed switching mechanism 300 sequentially drive the water path switching mechanism 110 to maintain the water path switching mechanism 110 and the water distribution mechanism in the state before the water was shut off. This period can be 5 seconds, 10 seconds, or other times, and can be designed according to market demand. When the water outlet device in the hot water state shuts off and then quickly turns on again, the instantaneous switching mechanism 200 drives the water path switching mechanism 110 to activate the water distribution mechanism and switch the water output effect. Through the action of the water distribution mechanism, water can be selectively controlled from pressure chamber 1 to achieve different water output effects. The instantaneous switching mechanism 200 enables cyclical switching of water output effects when the water outlet device continuously and rapidly switches on and off. By coordinating the delay switching mechanism 300 and the instantaneous switching mechanism 200, the water flow effect before the water outlet was turned off can be maintained when the water outlet is turned off and then back on for an extended period. This provides convenience for users who need to use the same water flow effect intermittently over a relatively long period. When the water outlet is flowing, the delay switching mechanism 300 and the instantaneous switching mechanism 200 are located away from the water path switching mechanism 110. When the water outlet is turned off, the delay switching mechanism 300 and the instantaneous switching mechanism 200 are located closer to the water path switching mechanism 110, thereby rotating the water path switching mechanism 110.

[0072] Figure 12 Show Figure 5 Sectional view along the DD direction; Figure 13 Show Figure 12 A magnified view of a section marked H; Figure 14 Show Figure 12 A magnified view of the structure marked "I" in the middle. (Refer to...) Figures 12-14 The water distribution mechanism includes multiple water distribution valve assemblies. Each water distribution valve assembly includes a functional valve shaft 120, which corresponds to the pressure chamber 1. When the water circuit switching mechanism 110 rotates, it can selectively drive the functional valve shaft 120 to open the outlet of the corresponding pressure chamber 1.

[0073] Specifically, in this embodiment, the water distribution valve assembly is specifically disposed on the water distribution body 30, and also includes a functional valve body 150 and a sealing ring 160. The water distribution body 30 is provided with a mounting groove 31, such as... Figure 3 As shown, the water distribution valve assembly is disposed in the mounting groove 31, and the functional valve shaft 120 is coaxially and movably inserted through the functional valve body 150, as shown. Figures 12-14As shown. The sealing ring 160 is arranged around the functional valve shaft 120. When the functional valve shaft 120 moves along the axial direction of the functional valve body 150 away from the water circuit switching mechanism 110, the sealing ring 160 can abut against the side wall of the functional valve body 150, thereby blocking the pressure relief passage 11, as shown. Figure 13 As shown; when the functional valve shaft 120 moves along the axial direction of the functional valve body 150 toward the direction close to the water circuit switching mechanism 110, the sealing ring 160 can disengage from the side wall of the functional valve body 150, thereby opening the pressure relief passage 11, as shown. Figure 14 As shown.

[0074] Figure 15 A schematic diagram of the water circuit switching mechanism according to Embodiment 1 of this utility model is shown. More specifically, the water distribution valve assembly also includes a movable ball 130. Each movable ball 130 corresponds to a functional valve shaft 120 and is disposed between one end of the functional valve shaft 120 and the water circuit switching mechanism 110. The other end of the functional valve shaft 120 is provided with a functional valve shaft elastic element 140. The water circuit switching mechanism 110 is provided with a plurality of control slots 113 along its circumference, such as... Figure 15 As shown, when the water circuit switching mechanism 110 rotates to the position where any control slot 113 is directly opposite the movable ball 130, the movable ball 130 can move into the control slot 113 under the action of the elastic element 140 of the functional valve shaft. The functional valve shaft 120 can then move closer to the water circuit switching mechanism 110 under the action of the elastic element 140 of the functional valve shaft, thereby opening the outlet of the corresponding pressure chamber 1. Figure 14 As shown.

[0075] Continue to refer to Figure 1 , Figure 10 and Figure 11 The water distribution mechanism also includes multiple pilot valves 400. Each pilot valve 400 corresponds to one of the pressure chambers 1. Each pilot valve 400 includes a pilot valve body 410 with an annular gap 411. When water enters the shower head, the water from the water inlet mechanism 20 first enters the water inlet channel, and then enters the corresponding pressure chamber 1 through the annular gaps 411 of the multiple pilot valves 400. Since the water inlet volume of the annular gap 411 is less than the water outlet volume of the pressure relief channel 11, the travel of the functional valve shaft 120 is relatively short, which can shorten the switching stroke of the functional valve shaft 120.

[0076] Reference Figure 13 and Figure 14The functional valve shaft 120 can control the connection and disconnection between the pressure relief channel 11 and the pressure chamber 1. The rotation of the water circuit switching mechanism 110 drives the functional valve shaft 120 to open and close 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 main flow channel of the pilot valve is opened, and the water in the main flow channel of the pilot valve and the pressure relief channel 11 merge together in the downstream outlet chamber 13.

[0077] Specifically, the pilot valve 400 also includes an on / off elastic element 420, which is coaxial with and abuts against the pilot valve body 410. The on / off elastic element 420 is specifically located above the pilot valve body 410. When the water in the pressure chamber 1 flows out through the corresponding pressure relief channel 11 to relieve pressure, the on / off elastic element 420 is compressed under the action of water pressure. At this time, the water in the main flow channel of the pilot valve corresponding to the pressure chamber 1 and the pressure relief channel 11 merge and flow out downstream.

[0078] More specifically, the opening and closing elastic element 420 is provided with a clearing rod 421, which can extend into the annular gap 411. When the pilot valve body 410 moves under the action of water pressure changes in the pressure chamber 1, the clearing rod 421 can extend and retract within the annular gap 411. Through the clearing rod 421, scale or impurities in the annular gap 411 can be removed during each compression and recovery process of the opening and closing elastic element 420, preventing the annular gap 411 from becoming clogged.

[0079] Figure 6 Show Figure 5 Sectional view along the AA direction. Figure 8 Show Figure 5 Sectional view along the BB direction. (Refer to...) 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 path switching mechanism 110 to rotate in different directions. After the shower head is turned off for a period of time while in the hot water state, the instantaneous switching mechanism 200 and the delayed switching mechanism 300 sequentially push the water path switching mechanism 110 to rotate, so that the water path switching mechanism 110 remains in the state before the water was turned off. It should be noted that after the instantaneous switching valve shaft 220 completes the drive of the water path switching mechanism 110, it can move away from the water path switching mechanism 110 and separate from the first circumferential ratchet 111, so that the delayed switching valve shaft 320 can subsequently drive the water path switching mechanism 110. When the shower head is turned off and then quickly turned on again while in the hot water state, the instantaneous switching mechanism 200 pushes the water path switching mechanism 110 to rotate, switching the water output effect.

[0080] Specifically, the waterway switching mechanism 110 is provided with a first circumferential ratchet 111 and a second circumferential ratchet 112, such as Figure 15 As shown. The ratchet direction of the first circumferential ratchet 111 is opposite to that of the second circumferential ratchet 112. The instantaneous switching mechanism 200 and the delayed switching mechanism 300 are disposed opposite to each other, and the waterway switching mechanism 110 is disposed between the instantaneous switching mechanism 200 and the delayed switching mechanism 300. The instantaneous switching mechanism 200 can engage with the first circumferential ratchet 111, and the delayed switching mechanism 300 can engage with the second circumferential ratchet 112.

[0081] 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. The instantaneous switching valve body 210 forms a first control chamber 211, which is connected to the water inlet mechanism 20 of the shower head. Water from the water inlet mechanism 20 can enter the first control chamber 211 to increase the pressure within it. The first spring seat 260 is fixedly mounted on the water distribution 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, with one end extending towards the water path switching mechanism 110 and the other end having the instantaneous switching elastic element 230 attached to it. The end of the instantaneous switching elastic element 230 away from the water path switching mechanism 110 abuts against the first spring seat 260.

[0082] Reference Figure 6 After the water outlet device is filled with water, the instantaneous switching valve shaft 220 is subjected to the first area difference between the first sealing ring 212 between it and the instantaneous switching valve body 210 and the sealing ring set on its own periphery. 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 circuit switching mechanism 110.

[0083] It should be noted that when the instantaneous switching valve shaft 220 is far away from the water circuit switching mechanism 110, the water inlet of the water inlet mechanism 20 can enter the corresponding pressure chamber 1 through the annular gap 411 of the multiple pilot valves 400 respectively.

[0084] More specifically, the delay switching mechanism 300 includes a delay switching valve body 310, a delay switching valve shaft 320, a delay switching elastic element 330, and a second spring seat 360. The delay switching valve body 310 internally forms a second control chamber 311, which is connected to the water inlet mechanism 20 of the shower head. Water from the water inlet mechanism 20 can enter the second control chamber 311 to increase the pressure in the second control chamber 311. The delay switching valve shaft 320 passes through the second control chamber 311, with one end extending towards the water path switching mechanism 110 and the other end provided with the delay switching elastic element 330. The second spring seat 360 is fixedly mounted on the water distribution seat 40, and the end of the delay switching elastic element 330 away from the water path switching mechanism 110 abuts against the second spring seat 360.

[0085] Continue to refer to Figure 6 After the water outlet device is filled with water, the delay switching valve shaft 320 is subjected to the second area difference between the second sealing ring 312 between it and the delay switching valve body 310 and the sealing ring provided on its own periphery. 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 delay switching elastic element 330, the delay switching valve shaft 320 moves away from the water circuit switching mechanism 110.

[0086] Figure 4 yes Figure 3 A magnified view of the structure marked J in the middle; for a more detailed view, please refer to [link / reference]. Figure 3 and Figure 4 The instantaneous switching mechanism 200 also includes a plurality of first guide posts 250. These first guide posts 250 are spaced apart, and the instantaneous switching valve shaft 220 is located between them. The first guide posts 250 provide guidance for the movement of the instantaneous switching valve shaft 220. A first protrusion 221 and a second protrusion 222 are respectively provided 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 the other first guide post 250. When the water outlet is shut off, the first protrusion 221 interacts with the corresponding first guide post 250, causing the head of the instantaneous switching valve shaft 220 to abut against the first circumferential ratchet 111, and driving the water circuit switching mechanism 110 to rotate through a certain angle. Then the second protrusion 222 interacts with the corresponding first guide post 250, causing the head of the instantaneous switching valve shaft 220 to disengage from the first circumferential ratchet 111. Only then can the delayed switching valve shaft 320 subsequently act on the water circuit switching mechanism 110.

[0087] Similarly, the delay switching mechanism 300 also includes a second guide post 350, which can provide guidance for the movement of the delay switching valve shaft 320.

[0088] In other words, the first guide post 250 and the second guide post 350 can respectively ensure the stability and accuracy of the instantaneous switching valve shaft 220 and the delayed switching valve shaft 320 during operation.

[0089] Figure 7 Show Figure 6 A magnified view of a section marked E in the middle; Figure 9 Show Figure 8 A magnified view of the structure marked F in the middle. (Refer to...) Figure 2 and Figures 6-9 The first control chamber 211 is connected to an instantaneous drain valve 240, which drains water quickly. After the water is turned off, the instantaneous switching valve shaft 220, under the action of the instantaneous switching elastic element 230, approaches and pushes the water circuit switching mechanism 110 to rotate. The second control chamber 311 is connected to a delayed drain valve 340, which drains water at a slower speed. The delayed switching valve shaft 320, under the action of the delayed switching elastic element 330, approaches and pushes the water circuit switching mechanism 110 to rotate. The drainage speed of the instantaneous drain valve 240 is greater than that of the delayed drain valve 340.

[0090] Specifically, such as Figure 7 As shown, the delayed drain valve 340 drains water through the drain gap 341, as... Figure 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; therefore, the drainage speed of the drain channel 241 is greater than that of the drain gap 341. When the water is turned off after the shower head sprays hot water, both the delay switching valve shaft 320 and the instantaneous switching valve shaft 220 will approach the water circuit switching mechanism 110 to reset. Their reset speeds are related to the drainage speeds of the delay drain valve 340 and the instantaneous drain valve 240, respectively. Since the drainage speed of the delay drain valve 340 is much smaller than that of the instantaneous drain valve 240, the instantaneous switching valve shaft 220 can reset faster. In other words, when the water is continuously and rapidly switched on and off, the water circuit switching mechanism 110 can be continuously controlled and rotated by the instantaneous switching valve shaft 220, thereby continuously switching the water output effect. When the shower head sprays water for an extended period while in a hot state, the delayed drain valve 340 drains the water. Only then will the delayed switching valve shaft 320 reset under the action of the delayed switching elastic element 330. After being driven clockwise by the instantaneous switching valve shaft 220, the water circuit switching mechanism 110 rotates counterclockwise by the same angle under the driving action of the delayed switching valve shaft 320, thus maintaining the water circuit switching mechanism 110 in the state before the water was turned off, i.e., maintaining the water output effect before the water was turned off.

[0091] This embodiment also provides a water path switching method, which achieves switching of water output effect based on the water outlet device provided in this embodiment. The water path switching method specifically includes the following steps:

[0092] Step S1: Turn on the overhead shower and let water in through the water inlet mechanism 20;

[0093] Step S2: When water enters the water outlet device, the instantaneous switching mechanism 200 and the delayed switching mechanism 300 can move away from the water path switching mechanism 110, and water enters the pressure chamber 1. At this time, the water path switching mechanism 110 selects one of the pressure chambers 1 to control water to exit, thereby achieving a water outlet effect.

[0094] Step S3: When the water outlet device is in the hot water state, the instantaneous switching mechanism 200 and the delayed switching mechanism 300 sequentially drive the water path switching mechanism 110, so that the water path switching mechanism 110 rotates in two opposite directions at the same angle 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 again.

[0095] When the water outlet device is turned off and then quickly turned on again while it is in the hot water state, the delay 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 then the water circuit switching mechanism 110 is activated, which can control the water outlet of the other pressure chamber 1 to achieve the switching of water outlet effect.

[0096] Example 2

[0097] This embodiment provides a water outlet device. The only difference between this embodiment and Embodiment 1 is the specific water distribution method of the water distribution mechanism.

[0098] Figure 15 This diagram shows a partial cross-sectional view of the overhead shower provided in Embodiment 2 of the present invention. Figure 1 ; Figure 16 This diagram shows a partial cross-sectional view of the overhead shower provided in Embodiment 2 of the present invention. Figure 2 . Reference Figure 15 and Figure 16In this embodiment, the water outlet device does not include the pressure chamber 1 found in Embodiment 1. The water inlet mechanism 20 is directly connected to the water flow channel 14. The water flow channel 14 corresponds to multiple water outlets 12, and each water outlet 12 corresponds to a different water outlet chamber 13. Different water outlet chambers 13 correspond to different water outlet effects. The rotation of the water path switching mechanism 110 can drive the water distribution 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 along the axial direction of the functional valve shaft 120. By moving the water distribution mechanism along this straight line, the two water outlets 12 can be opened alternately, thereby achieving the switching of water outlet effects.

[0099] More specifically, the water distribution mechanism includes a water distribution valve assembly, the structure of which can be the same as in Embodiment 1. The functional valve shaft 120 is disposed in the water distribution space. The rotation of the water path switching mechanism 110 can drive the functional valve shaft 120 to perform a linear movement along its axial direction. Figure 15 and Figure 16 Switching between the two positions shown allows for alternating opening of the outlet 12 of the water flow channel 14, thus switching the water flow effect.
