Description

Technical Field

[0001] This invention relates to the field of bathroom fixtures technology, and in particular to a water outlet device, a shower head, a drive device, and a water circuit switching method. 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 need to use the same water flow effect intermittently over a longer period.

[0004] Therefore, there is an urgent need for a water outlet device, a shower head overhead spray, and a water path switching method to solve the above problems. Summary of the Invention

[0005] According to one aspect of the present invention, the objective is to overcome the shortcomings of the prior art.

[0006] To achieve this objective, the present invention employs one of the following technical solutions: a water outlet device, comprising:

[0007] Waterway switching mechanism;

[0008] The water distribution mechanism is connected to the water path switching mechanism, and the action of the water path switching mechanism drives the action of the water distribution mechanism; and

[0009] The first mechanism and the second mechanism can both drive the waterway switching mechanism to operate.

[0010] The water outlet device shuts off the water and the duration exceeds t. The first mechanism first drives the water circuit switching mechanism to move in the first direction, and then the second mechanism drives the water circuit switching mechanism to move in the second direction. The first direction and the second direction are opposite.

[0011] When the water outlet device shuts off the water and the duration does not exceed t, only the first mechanism drives the water circuit switching mechanism to move in the first direction.

[0012] If the water is shut off and the duration exceeds t, the first and second mechanisms successively drive the water circuit switching mechanism to bring the water distribution mechanism into the state before the water is shut off.

[0013] If the water is shut off and the duration does not exceed t, only the first mechanism drives the water circuit switching mechanism to drive the water distribution mechanism to switch the water output effect.

[0014] The waterway switching mechanism is rotatably configured such that both the first and second mechanisms can push the waterway switching mechanism to rotate, and the directions of rotation are opposite.

[0015] After the first mechanism pushes the waterway switching mechanism to rotate, it disengages from the waterway switching mechanism.

[0016] The first mechanism includes a sliding first shaft, the first shaft is provided with a second protrusion, and a fixed first guide post is also provided. The first shaft moves as follows: firstly, the first shaft acts on the water channel switching mechanism to push the water channel switching mechanism to rotate, and then the second protrusion is pushed by the first guide post to make the first shaft move away from the water channel switching mechanism.

[0017] The first shaft is also provided with a first protrusion and another fixed first guide post. During the movement of the first shaft: firstly, the first protrusion acts on the other first guide post to make the first shaft push the water channel switching mechanism to rotate, and then the second protrusion is pushed by the first guide post.

[0018] The waterway switching mechanism includes a ratchet with circumferential ratchet teeth. Both the first and second mechanisms can engage the circumferential ratchet teeth to drive the waterway switching mechanism to rotate.

[0019] The circumferential ratchet consists of a first circumferential ratchet and a second circumferential ratchet with opposite ratchet directions. The first mechanism and the second mechanism can respectively abut against the first circumferential ratchet and the second circumferential ratchet, and drive the waterway switching mechanism to rotate in opposite directions.

[0020] The circumferential ratchet consists of a first circumferential ratchet and a second circumferential ratchet, both with the same ratchet direction. The first mechanism and the second mechanism can respectively abut against the first circumferential ratchet and the second circumferential ratchet and drive the waterway switching mechanism to rotate in the same direction.

[0021] The first circumferential ratchet is arranged in a ring array, and the second circumferential ratchet is arranged in a ring array, with the number of the first circumferential ratchet and the number of the second circumferential ratchet being equal.

[0022] The first mechanism includes a first control cavity, a first shaft slidably connected to the first control cavity, and a first elastic element. When water enters, the water force exerted by the water in the first control cavity on the first shaft is greater than the elastic force of the first elastic element. The force difference drives the first shaft away from the water switching mechanism. When the water is turned off, the first control cavity drains water, the first elastic element drives the first shaft to reset, and the water switching mechanism is activated by the reset of the first shaft.

[0023] The second mechanism includes a second control chamber, a second shaft slidably connected to the second control chamber, and a second elastic element. When water enters, the water in the second control chamber acts on the second shaft with a force greater than the elastic force of the second elastic element. The force difference drives the second shaft away from the water switching mechanism. When the water is turned off, the second control chamber drains water, and the second elastic element drives the second shaft to reset. The reset of the second shaft drives the water switching mechanism to operate.

[0024] After the water is turned off, the drainage speed of the first control chamber is greater than that of the second control chamber.

[0025] The first control chamber is connected to a first drain valve, through which the first control chamber drains water; the second control chamber is connected to a second drain valve, through which the second control chamber drains water; the drainage speed of the first drain valve is greater than the drainage speed of the second drain valve.

[0026] It includes multiple water outlets, and the water path switching mechanism is rotatably configured. The rotation of the water path switching mechanism drives the water distribution mechanism to open at least one water outlet.

[0027] It includes a switching space and a water distribution space, the water paths between the switching space and the water distribution space are not connected, the water path switching mechanism is set in the switching space, and the water distribution mechanism is set in the water distribution space.

[0028] It includes multiple cavities, and the water distribution space is multiple. The water distribution mechanism includes multiple third shafts, which are located in multiple water distribution spaces and correspond to multiple cavities. When the water path switching mechanism rotates, it can drive the third shafts to move so that the outlet of the corresponding cavity opens.

[0029] The water distribution mechanism includes multiple pilot valves. Each pilot valve is equipped with a sliding third shaft and a main channel. The opening and closing of the main channel is controlled by switching the pilot valves on and off. The opening and closing of the pilot valves is controlled by sliding the third shaft. At least one third shaft is slidable by rotating the water circuit switching mechanism.

[0030] The pilot valve includes a pilot valve body and a pressure relief channel. The pilot valve body moves between an open position and a closed position to control the opening and closing of the pilot valve. The space inside the pilot valve and on the pilot valve body forms a cavity, and the pilot valve body has a gap. The pressure relief channel is connected to the cavity, and the third shaft controls the opening and closing of the pressure relief channel. When the pressure relief channel is open, the cavity is depressurized to drive the pilot valve body to the open position. When the pressure relief channel is closed, the water inlet of the water inlet mechanism enters the cavity through the gap to drive the pilot valve body to the closed position.

[0031] The water distribution mechanism includes a water distribution valve assembly, which includes a sliding third shaft. The water distribution valve assembly is controlled by rotating the water path switching mechanism to drive the third shaft to slide.

[0032] The number of water distribution valve assemblies is multiple, and each water distribution valve assembly is equipped with a water outlet. By rotating the water circuit switching mechanism, at least one of them can drive the third axis to slide, thereby opening the water outlet corresponding to the selected water distribution valve assembly.

[0033] The water distribution valve assembly is provided with at least two water outlets, and the water outlets are switched by sliding the third axis.

[0034] The water path switching mechanism is provided with multiple control slots along the circumference, and the water path switching mechanism rotates to control the sliding of the third axis through the multiple control slots.

[0035] The water distribution valve assembly also includes a movable ball and a third elastic element. The movable ball is located between one end of the third shaft and the water path switching mechanism. The third elastic element abuts against the other end of the third shaft. When the water path switching mechanism rotates to the point where any control slot is directly opposite the movable ball, the movable ball moves to the control slot under the action of the third elastic element, and the third shaft slides to open the corresponding water outlet.

[0036] To achieve this objective, the present invention adopts the following second technical solution: a water outlet device, comprising:

[0037] Waterway switching mechanism;

[0038] The water distribution mechanism is connected to the water circuit switching mechanism. The water distribution mechanism includes multiple pilot valves. The action of the water circuit switching mechanism drives the water distribution mechanism to control the opening and closing of at least one pilot valve.

[0039] The first mechanism is equipped with an elastic element. The first mechanism can drive the water circuit switching mechanism to operate. When the water outlet device turns on the water, the elastic element stores energy under the action of water pressure. When the water outlet device turns off the water, the elastic element releases energy to drive the water circuit switching mechanism to operate.

[0040] The pilot valve is equipped with a sliding third shaft and a main channel. The opening and closing of the main channel is controlled by the opening and closing of the pilot valve, and the opening and closing of the pilot valve is controlled by the sliding of the third shaft. The third shaft is connected to the water circuit switching mechanism. When the water outlet device closes the water, the first mechanism drives the water circuit switching mechanism to operate. The water circuit switching mechanism drives at least one third shaft to slide through transmission.

[0041] To achieve this objective, the present invention adopts the following third technical solution: a shower head top spray, including a shower head housing, a face cover, and the aforementioned water outlet device. The water outlet device further includes a water inlet mechanism and a water distribution body. The shower head housing and face cover enclose an installation space. The water distribution body is provided with multiple water outlet chambers corresponding to multiple water outlet effects. The water inlet mechanism is located on the top of the shower head housing and can realize water inlet into the installation space. The water outlet device is located in the installation space and can discharge water through any of the water outlet chambers.

[0042] To achieve this objective, the present invention adopts the following fourth technical solution: a driving device, comprising:

[0043] Water inlet mechanism;

[0044] Event organizers, event setup; and

[0045] A first mechanism and a second mechanism, both of which can drive the active mechanism to move; both the first mechanism and the second mechanism can connect the water inlet mechanism, the water inlet mechanism shuts off the water and the duration exceeds t, the first mechanism first drives the active mechanism to move in a first direction, and then the second mechanism drives the active mechanism to move in a second direction; when the water is shut off and the duration does not exceed t, only the first mechanism drives the active mechanism to move in the first direction.

[0046] The movable mechanism is rotatably configured to form a rotating mechanism, and both the first mechanism and the second mechanism can drive the rotating mechanism to rotate.

[0047] The first mechanism disengages from the rotating mechanism after pushing it to rotate.

[0048] The rotating mechanism includes a ratchet with circumferential ratchet teeth. The first and second mechanisms can abut against the circumferential ratchet teeth to drive the rotating mechanism to rotate.

[0049] The first mechanism includes a first control cavity, a first shaft slidably connected in the first control cavity, and a first elastic element. When water enters, the water force exerted by the water in the first control cavity on the first shaft is greater than the elastic force of the first elastic element. The force difference drives the first shaft to move away from the rotating mechanism. When the water is turned off, the first control cavity drains water, the first elastic element drives the first shaft to reset, and the reset of the first shaft drives the rotating mechanism to operate.

[0050] The second mechanism includes a second control chamber, a second shaft slidably connected to the second control chamber, and a second elastic element. When water enters, the water force exerted by the water in the second control chamber on the second shaft is greater than the elastic force of the second elastic element. The force difference drives the second shaft to move away from the rotating mechanism. When the water is turned off, the second control chamber drains water, and the second elastic element drives the second shaft to reset. The reset of the second shaft drives the rotating mechanism to operate. After the water is turned off, the drainage speed of the first control chamber is greater than the drainage speed of the second control chamber.

[0051] It also includes a sliding third shaft, and the rotating mechanism is provided with multiple control slots along the circumference. The rotating mechanism rotates to control the sliding of the third shaft through the multiple control slots.

[0052] The third shaft is equipped with a movable ball and a third elastic element. The movable ball is located between one end of the third shaft and the rotating mechanism, and the third elastic element is located at the other end of the third shaft. When the rotating mechanism rotates to the point where any control slot is directly opposite the movable ball, the movable ball moves to the control slot and slides along the third shaft under the action of the third elastic element.

[0053] To achieve this objective, the present invention adopts the following fifth technical solution: the water path switching method of the water outlet device includes:

[0054] S1, Water enters the water outlet device;

[0055] S2. The first mechanism and the second mechanism are away from the water circuit switching mechanism, and the water outlet device outlets water in a certain state, which is defined as the first water outlet state.

[0056] S3. The water outlet device shuts off the water, and the selection is based on whether the water shut-off duration exceeds t:

[0057] If the time exceeds t, the first mechanism first drives the water path switching mechanism to move in the first direction and drives the water distribution mechanism to switch to the second water outlet state. Then the second mechanism drives the water path switching mechanism to move in the second direction and drives the water distribution mechanism to return to the first water outlet state.

[0058] If the time limit is not exceeded, only the first mechanism drives the water circuit switching mechanism to move and causes the water distribution mechanism to move in the first direction to switch to the second water outlet state.

[0059] The beneficial effects of this invention are as follows: The water outlet device includes a water path switching mechanism, a water distribution mechanism, a first mechanism, and a second mechanism. The water path switching mechanism can operate to drive the water distribution mechanism, thereby switching the water outlet effect. If the water is turned off and the water-off duration exceeds t, the first mechanism first drives the water path switching mechanism to move in the first direction, and then the second mechanism drives the water path switching mechanism to move in the second direction; if the duration does not exceed t, only the first mechanism drives the water path switching mechanism. Therefore, the water distribution mechanism can be controlled by whether the duration exceeds t, thus providing convenience for the user.

[0060] The first and second mechanisms can drive the water path switching mechanism to perform opposite actions. If the water shut-off time exceeds t, the first and second mechanisms drive the water path switching mechanism sequentially to maintain the water path switching mechanism and the water distribution mechanism in the state before the water shut-off. If the water shut-off time does not exceed t, only the first mechanism drives the water path switching mechanism to activate the water distribution mechanism and switch the water output effect. In other words, the water outlet device can achieve cyclical switching of the water output effect when the shower head and overhead spray are continuously and rapidly switched on and off (water shut-off time not exceeding t). When the water is turned on again after a long period of shutdown (water shut-off time exceeding t), it maintains the water output effect before the water shut-off. This provides convenience for users who intermittently use the same water output effect over a relatively long period. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0091] Example 1

[0092] Reference 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.

[0093] 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 various 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 41 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 outlet nozzles 61 for water outlet; the number of water outlet nozzles 61 is greater than the number of water outlet holes on the water distribution base 40.

[0094] 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 in 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 to the inlet pipe (not shown in the figure). The inlet ball head 22 is movably embedded in the top of the inlet seat 23, which facilitates the adjustment of the relative angle between the shower head housing 10 and the inlet ball head 22, that is, the adjustment of the water outlet angle of the shower head.

[0095] Reference Figures 2-5 , Figure 10 and Figure 11 The water outlet device has multiple cavities 1 corresponding to multiple water outlet effects, and each cavity 1 has a corresponding water outlet 12, which is connected to a water outlet chamber 13. The water outlet device in this embodiment includes a water path switching mechanism 110, a water distribution mechanism, a first mechanism 200, and a second mechanism 300. In this embodiment, the water path switching mechanism 110 is rotatable and includes a ratchet, which can actuate to drive the water distribution mechanism to open at least one of the corresponding cavity 1's water outlets.

[0096] 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 located in the switching space, and the water distribution mechanism is located in the water distribution space.

[0097] The first mechanism 200 and the second mechanism 300 can respectively drive the water path switching mechanism 110 to perform opposite actions. When the water outlet device in the open state turns off the water and then does not turn it back on, or turns it back on after a certain period (i.e., the water is turned off and the duration exceeds a predetermined time t), the first mechanism 200 and the second mechanism 300 sequentially drive the water path switching mechanism 110, keeping the water path switching mechanism 110 and the water distribution mechanism in their pre-turn-off state. Specifically, the first mechanism 200 first drives the water path switching mechanism 110, causing the water distribution mechanism to switch, changing the water outlet state. Then, the second mechanism 300 drives the water path switching mechanism 110, causing the water distribution mechanism to reset, and then switching back to the original water outlet state (pre-turn-off state). t can be 5 seconds, 10 seconds, or other times, and can be designed according to market demand. When the water outlet device in the open state turns off the water and then quickly turns it back on (i.e., the water is turned off and the duration does not exceed the predetermined time t), only the first mechanism 200 drives the water path switching mechanism 110 to activate, causing the water distribution mechanism to switch the water outlet effect. In this embodiment, the first mechanism 200 is an instantaneous switching mechanism, and the second mechanism 300 is a delayed switching mechanism. Through the operation of the aforementioned water distribution mechanism, at least one of the control chambers 1 can be selected to control water flow to achieve different water flow effects. The first mechanism 200 enables cyclical switching of water flow effects during continuous and rapid switching of the water outlet (within t). The cooperation of the second mechanism 300 and the first mechanism 200 maintains the water flow effect before it was turned off when the water outlet is turned off and then back on for a long period (exceeding t), providing convenience for users who intermittently use the same water flow effect over a longer period. When the water outlet is flowing, the second mechanism 300 and the first mechanism 200 are away from the water flow switching mechanism 110, and the water flow switching mechanism 110 remains stationary. When the water outlet is turned off, the first mechanism 200 and the second mechanism 300 move closer to the water flow switching mechanism 110 sequentially, or only the first mechanism 200 moves closer to the water flow switching mechanism 110 to drive its rotation.

[0098] Reference Figures 12-14 The water distribution mechanism includes multiple water distribution valve assemblies. Each water distribution valve assembly includes a third shaft 120, which corresponds to the cavity 1. The water path switching mechanism 110 rotates, which can selectively drive the third shaft to open the outlet of the corresponding cavity 1. In this embodiment, the third shaft 120 is a functional valve shaft.

[0099] In this embodiment, the water distribution valve assembly is disposed on the water distribution body 30, and it 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 third shaft 120 is coaxially and movably inserted through the functional valve body 150, as shown. Figures 12-14 As shown. The sealing ring 160 is disposed around the third shaft 120. When the third 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 channel 11, as shown. Figure 13 As shown; when the third shaft 120 moves along the axial direction of the functional valve body 150 toward 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 channel 11, as shown. Figure 14 As shown.

[0100] like Figure 3 As shown, the water distribution valve assembly also includes a movable ball 130. Each movable ball 130 corresponds to a third shaft 120 and is located between one end of the third shaft 120 and the water path switching mechanism 110. The other end of the third shaft 120 is provided with a third elastic element 140, which is a functional valve shaft elastic element. The water path switching mechanism 110 has multiple control slots 113 arranged in a circumferential array, with a tooth between each pair of adjacent control slots 113. When the movable ball corresponds to the tooth, the third elastic element 140 is compressed and stores energy, such as... Figure 15 As shown, when the water path switching mechanism 110 rotates from the convex tooth to the point where any control slot 113 is directly opposite the movable ball 130, the movable ball 130 moves into the control slot 113 under the action of the third elastic element 140. Simultaneously, the third shaft 120 moves towards the water path switching mechanism 110 to open the pressure relief channel 11 and thus open the outlet 12 of the corresponding cavity 1. Figure 14 As shown.

[0101] Reference Figure 1 , Figure 10 and Figure 11The water distribution mechanism also includes multiple pilot valves 400. Each pilot valve 400 corresponds to a cavity 1, and the cavity 1 constitutes the pressure chamber of the pilot valve 400. The pilot valve 400 includes a pilot valve body 410, and the space above the pilot valve body 410 within the pilot valve 400 constitutes the aforementioned pressure chamber. The pilot valve is opened and closed by moving the pilot valve body 410 between the open and closed positions. The pilot valve body 410 has a gap 411. When water enters the shower head, the water from the water inlet mechanism 20 first enters the water inlet channel 201, and then enters the corresponding pressure chamber through the gaps 411 of the multiple pilot valves 400 (such as entering the gap 411 from the annular cavity 401 of the water inlet channel 201). At this time, the pilot valve body 410 moves downward to the closed position under the water pressure of the pressure chamber (the pressure chamber is not depressurized), thereby blocking the annular cavity 401 and the outlet 12. Since the water inlet volume of the gap 411 is less than the water outlet volume of the pressure relief channel 11, the pressure relief speed is greater than the water inlet speed relative to the water inlet and pressure relief. Therefore, the movement stroke of the third shaft 120 is shorter, thus shortening the switching stroke of the third shaft 120.

[0102] Reference Figure 13 and Figure 14 One end of the pressure relief channel 11 is connected to the pressure chamber, and the third shaft 120 can control the opening and closing of the pressure relief channel 11. The rotation of the water circuit switching mechanism 110 drives the third shaft 120 to control the opening and closing of the pressure relief channel 11, thereby controlling whether the pressure chamber of the pilot valve 400 is depressurized, and thus controlling the opening and closing of the pilot valve 40. Before depressurization, under the action of water pressure in the pressure chamber (specifically, the water pressure force of the pressure chamber + the elastic force of the opening and closing elastic element 420 - the water pressure force of the annular cavity 401), the main flow channel 403 of the pilot valve is closed. At this time, the corresponding outlet 12 of the pilot valve and the inlet mechanism 20 are disconnected (blocked). When the pressure chamber is depressurized (specifically, the water pressure force of the annular cavity 401 - the elastic force of the opening and closing elastic element 420), the main flow channel 403 of the pilot valve opens. At this time, the outlet 12 corresponding to the pilot valve and the water inlet mechanism 20 (such as the annular cavity 401 of the water inlet flow channel 201) are connected. The water in the main flow channel 403 of the pilot valve and the pressure relief channel 11 converge downstream, such as in the downstream outlet cavity 13, resulting in the water output effect corresponding to the outlet cavity 13. The water path switching mechanism 110 controls the sliding of the third axis of at least one selectable water distribution valve assembly to open the pressure relief channel 11 of the pilot valve corresponding to the selectable water distribution valve assembly, thereby releasing pressure in the pressure chamber of the pilot valve corresponding to the selectable water distribution valve assembly, opening the pilot valve corresponding to the selectable water distribution valve assembly, and connecting the outlet and inlet mechanism of the selectable pilot valve to discharge water from the outlet chamber 13 of the selectable pilot valve, thus achieving the corresponding water discharge effect. However, this is not a limitation; the water path switching mechanism 110 can also drive the water distribution plate to rotate, directly achieving water path switching by rotating the water distribution plate (which has water passage holes, and the water distribution body has multiple water distribution holes, with the water passage holes aligned or staggered to select one water distribution hole, from which water is discharged).

[0103] The pilot valve 400 also includes an opening and closing elastic element 420, which is coaxial with and abuts against the pilot valve body 410. The opening and closing elastic element 420 is located above the pilot valve body 410, i.e., within the pressure chamber. When the water in the pressure chamber flows out through the corresponding pressure relief channel 11 to relieve pressure, the opening and closing elastic element 420 is compressed under the action of water pressure. The water pressure force in the annular cavity 401 is greater than the elastic force of the opening and closing elastic element 420. At this time, the pilot valve body 410 moves upward to the open position under the action of water pressure. The water in the pilot valve main channel 403 and the pressure relief channel 11 corresponding to this pressure chamber merge and flow out downstream.

[0104] The opening and closing elastic element 420 includes a spiral segment, which is also connected to a drain rod 421. The drain rod 421 can extend into the gap 411. When the pilot valve body 410 moves under the action of water pressure changes in the pressure chamber, the spiral segment can be compressed, and the pilot valve body 410 can slide, allowing the drain rod 421 to slide in the annular gap 411. Through each compression and recovery process of the opening and closing elastic element 420, the drain rod 421 removes scale or impurities from the gap 411, preventing blockage. The pilot valve body 410 may include a diaphragm 4001 and a vertically movable valve seat 4002. The valve seat 4002 is mounted in the middle region of the diaphragm 4001, and the periphery of the diaphragm 4001 is fixed. The gap 411 is fixedly passed through the valve seat 4002 and the diaphragm 4001.

[0105] Reference Figure 1 , Figure 3 , Figure 6 and Figure 8 The first mechanism 200 and the second 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 (t) while in the hot water state, the first mechanism 200 and the second mechanism 300 successively 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 first shaft 220 completes the drive of the water path switching mechanism 110, it can disengage from the water path switching mechanism 110, such as separating from the first circumferential ratchet 111, so that the second shaft 320 can drive the water path switching mechanism 110 in the future. The disengagement or non-disengagement achieves the engagement / disengagement state. After the shower head is turned off while in the hot water state, it is quickly turned on again (less than t), and the first mechanism 200 pushes the water path switching mechanism 110 to rotate, switching the water output effect.

[0106] The waterway switching mechanism 110 is equipped with a first circumferential ratchet 111 and a second circumferential ratchet 112, such as Figure 15As shown. The ratchet direction of the first circumferential ratchet 111 is opposite to that of the second circumferential ratchet 112. The first mechanism 200 and the second mechanism 300 are arranged opposite to each other, and the water channel switching mechanism 110 is disposed between the first mechanism 200 and the second mechanism 300. For example, the first mechanism 200 and the second mechanism 300 are respectively arranged on both sides of the water channel switching mechanism 110 (e.g., respectively arranged on the left and right sides), and located on the same side of the rotation axis (e.g., both located on the front side, or both located on the rear side). The first mechanism 200 can cooperate to abut against the first circumferential ratchet 111, and the second mechanism 300 can cooperate to abut against the second circumferential ratchet 112, so that the first mechanism 200 and the second mechanism 300 drive the water channel switching mechanism 110 to rotate in opposite directions. In this embodiment, the number of the first circumferential ratchet 111 and the second circumferential ratchet 112 is equal, so each time the first mechanism 200 and the second mechanism 300 approach the water channel switching mechanism 110 (approaching the position), they can drive the water channel switching mechanism 110 to rotate. However, other arrangements can also be adopted, such as the first mechanism and the second mechanism being located on the same side of the waterway switching mechanism 110 and arranged on both sides of the rotation axis, with the two mechanisms driving the ratchet to rotate in opposite directions.

[0107] The first mechanism 200 includes a first valve body 210, a first shaft 220, a first elastic element 230, and a first spring seat 260. In this embodiment, the first valve body 210 is an instantaneous switching valve body, the first shaft 220 is an instantaneous switching shaft, and the first elastic element 230 is an instantaneous switching elastic element. A first control chamber 211 is formed inside the instantaneous switching valve body. The first control chamber 211 is connected to the water inlet mechanism 20 of the shower head, allowing water from the water inlet mechanism 20 to enter the first control chamber 211 and increase its pressure. The first spring seat 260 is fixedly mounted on the water distribution seat 40, and one end of the instantaneous switching elastic element abuts against the first spring seat 260. The instantaneous switching shaft passes through the first control chamber 211, with one end extending toward the water path switching mechanism 110. This extension extends beyond the first control chamber 211 but does not pass through water. The water path switching mechanism 110 is not connected to the water inlet mechanism 20, meaning the instantaneous switching shaft does not extend into the water inlet channel of the water inlet mechanism. The other end is provided with an instantaneous switching elastic element, the end of which, away from the water path switching mechanism 110, abuts against the first spring seat 260. In this specific embodiment, the instantaneous switching shaft is isolated from the water inlet channel 201. (Refer to...) Figure 6After the water outlet device is energized, the instantaneous switching shaft is subjected to the first area difference between the first sealing ring 212 between itself and the instantaneous switching valve body and the sealing ring 213 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, that is, the water pressure force exerted by the water on the first shaft 220 is greater than the elastic force exerted by the first elastic element 230 on the first shaft 220, this force difference drives the instantaneous switching shaft to move away from the water circuit switching mechanism 110. It should be noted that when the instantaneous switching shaft moves away from the water circuit switching mechanism 110, the water inlet mechanism 20 can enter the corresponding pressure chamber through the gaps 411 of the multiple pilot valves 400 respectively.

[0108] The second mechanism 300 includes a second valve body 310, a second shaft 320, a second elastic element 330, and a second spring seat 360. In this embodiment, the second valve body 310 is a time-delay switching valve body, the second shaft 320 is a time-delay switching shaft, and the second elastic element 330 is a time-delay switching elastic element. A second control chamber 311 is formed inside the time-delay switching valve body. The second control chamber 311 is connected to the water inlet mechanism 20 of the shower head, and the water inlet mechanism 20 can enter the second control chamber 311 to increase the pressure in the second control chamber 311. The water outlet device includes a water-passing zone and a non-water-passing zone. The delayed switching shaft passes through the second control cavity 311, with one end extending towards the water path switching mechanism 110. This extension extends outside the second control cavity 311 but does not pass through water. The water path switching mechanism 110 is not connected to the water inlet mechanism 20, meaning the delayed switching shaft does not extend into the water inlet channel of the water inlet mechanism. The water inlet channel, water distribution mechanism, etc., are located in the water-passing zone, while the water path switching mechanism 110 is located in the non-water-passing zone. After the water flows in from the water inlet channel, it goes directly to the water distribution mechanism without passing through the water path switching mechanism 110, thus avoiding pressure division by the water path switching mechanism 110. In this way, the water flows from the water inlet channel to the first control cavity 211 and the second control cavity 311, generating a water force on the first shaft 220 and the second shaft 320. The starting water pressure will be significantly lower than when the water path switching mechanism 110 is located in the water-passing zone. The other end is provided with a delayed switching elastic element, and the second spring seat 360 is fixedly mounted on the water distribution seat 40. The end of the delayed switching elastic element away from the water path switching mechanism 110 abuts against the second spring seat 360. In this specific embodiment, the delayed switching shaft is isolated from the water inlet channel 201. (Refer to...) Figure 6 After the water outlet device is filled with water, the delay switching shaft is subjected to the second area difference between the second sealing ring 312 between it and the delay switching valve body and the sealing ring 313 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, that is, the water pressure force of the water acting on the second shaft 320 is greater than the elastic force of the second elastic element 330 acting on the second shaft 320, the force difference drives the delay switching shaft to move away from the water circuit switching mechanism 110.

[0109] Reference Figure 3 and Figure 4 The first mechanism 200 also includes a plurality of first guide posts 250, such as two first guide posts 250. The plurality of first guide posts 250 are spaced apart, and the first shaft 220 is located between the plurality of first guide posts 250. The first guide posts 250 provide guidance for the movement of the first shaft 220. A first protrusion 221 and a second protrusion 222 are respectively provided on opposite sides of the first shaft 220, with the first protrusion 221 in front and the second protrusion 222 behind. The first protrusion 221 corresponds to one first guide post 250, and the second protrusion 222 corresponds to the other first guide post 250. After the water outlet is shut off, the movement of the first shaft 220 proceeds as follows: First, the first protrusion 221 interacts with the corresponding first guide post 250, causing the head of the first shaft 220 to abut against the first circumferential ratchet 111, and driving the water path switching mechanism 110 to rotate through a certain angle; then, the second protrusion 222 interacts with the corresponding first guide post 250, pushing the first shaft 220 outward so that the head of the first shaft 220 disengages from the first circumferential ratchet 111. Only then can the second shaft 320 subsequently operate on the water path switching mechanism 110. Similarly, the second mechanism 300 also includes a second guide post 350, which provides guidance for the movement of the second shaft 320. In other words, the first guide post 250 and the second guide post 350 respectively ensure the stability and accuracy of the first shaft 220 and the second shaft 320 during operation.

[0110] Reference Figure 2 and Figures 6-9 The first control chamber 211 is connected to a first drain valve 240. After the water is turned off, the first control chamber 211 drains water quickly through the first drain valve 240. Under the action of the first elastic element 230, the first shaft 220 approaches and pushes against the water path switching mechanism 110 to rotate. The second control chamber 311 is connected to a second drain valve 340. The second control chamber 311 drains water slowly through the second drain valve 340. The second shaft 320 can approach and push against the water path switching mechanism 110 to rotate under the action of the second elastic element 330. The drainage speed of the first drain valve 240 is greater than that of the second drain valve 340. The first drain valve 240 is an instantaneous drain valve, and the second drain valve 340 is a delayed drain valve.

[0111] like Figure 7 As shown, the delayed drain valve drains water through the drain gap 341, as... Figure 9As shown, the instantaneous drain valve drains water through the drain channel 241. The drain area of ​​the drain channel 241 is much larger than that of the drain gap 341, therefore the drain speed of the drain channel 241 is much greater than that of the drain gap 341. When the water is turned off after the shower head sprays water, both the delay switching shaft and the instantaneous switching shaft will return to their original positions near the water circuit switching mechanism 110 under the action of the elastic element. Their return speeds are related to the drain speeds of the delay drain valve and the instantaneous drain valve, respectively. Since the drain speed of the delay drain valve is much smaller than that of the instantaneous drain valve, the instantaneous switching shaft can return to its original position more quickly. That is, when the water is switched on and off continuously and rapidly (within t), the instantaneous drain valve drains water, and the water circuit switching mechanism 110 can be continuously controlled and rotated by the instantaneous switching shaft, thereby continuously switching the water output effect. During this process, the delay drain valve has not yet finished draining, the delay switching shaft has not yet returned to its original position, and it does not act on the water circuit switching mechanism. When the shower head is in the hot water state and the water shut-off time is relatively long (exceeding t), the instantaneous drain valve drains water, and the water circuit switching mechanism 110 is driven by the instantaneous switching shaft to rotate clockwise by a certain angle, switching the water output effect. The delayed drain valve drains water, and the delayed switching shaft is reset under the action of the delayed switching elastic element. After the water is drained, the delayed switching shaft is reset to its original position, and the water circuit switching mechanism 110 is driven by the delayed switching shaft to rotate counterclockwise by the same angle, switching back to the original water output effect, so that the water circuit switching mechanism 110 maintains the state before the water shut-off, that is, maintains the water output effect before the water shut-off.

[0112] like Figure 9 As shown, the first drain valve 240 connects to the first control chamber 211 and cooperates with the drain channel 241. It includes a first movable valve 242 and a first elastic body 243 that abuts against the first movable valve 242. When the water is turned on, the water flow opens the first movable valve 242. The force exerted by the water on the first movable valve 242 is greater than the elastic force of the first elastic body 243, causing the first movable valve to move downward to seal the drain channel 241. The water flows into the first control chamber 211. When the water is stopped, the water force decreases or disappears, and the elastic force of the first elastic body 243 drives the first movable valve 242 to move upward to open the drain channel 241, allowing the first control chamber 211 to drain water quickly. Depending on the needs, the second drain valve 340 can be configured with the same structure as the first drain valve, the only difference being that the second drain valve has a smaller drainage area and a slower drainage speed. However, the following explanation uses other structures as examples.

[0113] In this embodiment, as Figure 2-3 , Figure 6-10 , Figure 13As shown, the water outlet device is provided with an inlet channel 201, which includes an inlet path 2001, a connecting cavity 2002, a first water inlet 2004, an inlet cavity 2005, a second water inlet 2006, and a third water inlet 2007. One end of the inlet path 2001 is connected to the inlet mechanism 20, and the other end is the inlet 2003 connected to the connecting cavity 2002. The first water inlet 2004 connects the connecting cavity 2002 and the first control cavity 211. The first control cavity 211 is connected to the third water inlet 2007. The third water inlet 2007 is connected to the inlet cavity 2005. The second water inlet 2006 connects the connecting cavity 2002 and the second control cavity 311. After water enters, the water flow can enter the first control chamber 211 via the water inlet mechanism 20, water inlet path 2001, connecting chamber 2002, and first water inlet 2004; the water flow can enter the water inlet chamber 2005 via the water inlet mechanism 20, water inlet path 2001, connecting chamber 2002, first water inlet 2004, first control chamber 211, and third water inlet 2007; and the water flow can enter the second control chamber 311 via the water inlet mechanism 20, water inlet path 2001, connecting chamber 2002, and second water inlet 2006.

[0114] In this embodiment, the water inlet 2003 and the drainage channel 241 are vertically aligned. The first movable valve 242 connects the water inlet 2003 and the drainage channel 241. When the water is turned on, the water flow enters the connecting cavity 2002 through the water inlet 2003 and acts on the first movable valve 242 to move downwards to seal the drainage channel 241. When the water is stopped, the first elastic body 243 resets to open the drainage channel 241 to discharge the water in the first control cavity 211. Drainage: First control cavity 211 -- first water inlet 2004 -- connecting cavity 2002 -- drainage channel 241 to discharge the water in the first control cavity 211.

[0115] like Figure 6-8As shown, the second water inlet 2006 is equipped with the second drain valve 340, which includes a one-way valve and a drain gap 341. Water enters through the flow of water from the connecting chamber 2002 to the second water inlet 2006, causing the one-way valve to open. After opening, the water in the connecting chamber 2002 flows through the second water inlet 2006 and the drain gap 341 into the second control chamber 311. After the water is turned off, the one-way valve resets to close the second water inlet 2006. Because of the drain gap 341, the water in the second control chamber 311 is discharged through the drain gap 341. For example: second control chamber 311 -- drain gap 341 -- connecting chamber 2002 -- drain channel 241. The one-way valve includes a second movable valve 342 and a second elastic body 343 that abuts against the second movable valve 342. The second movable valve 342 is provided with the aforementioned drainage gap 341. The second elastic body 343 includes a spiral section and a straight section extending from the end of the spiral section along a direction parallel to the axis. The straight section is inserted into the drainage gap 341, which serves as a positioning and guiding function to reduce the water flow area and remove scale.

[0116] like Figure 11 As shown, the pilot valve 400 has an outlet 12 and an annular cavity 401. The annular cavity 401 surrounds the outlet 12 and is blocked by a blocking ring 402, which is formed on the water distribution body. When the pilot valve body 410 is sealed and connected to the end face of the blocking ring 402, it blocks the communication between the annular cavity 401 and the outlet 12, and the pilot valve 400 is closed, and the main flow channel 403 of the pilot valve body 410 is closed. When the pilot valve body 410 moves upward away from the end face of the blocking ring 402, the annular cavity 401 and the outlet 12 are closed. With outlet 12 connected, pilot valve 400 opens, and the main flow channel 403 of pilot valve body 410 opens; the inlet chamber 2005 connects to the annular chamber 401 of each pilot valve 400, and each outlet 12 connects to each outlet chamber 13. Therefore, the sequence is: inlet mechanism 20 -- inlet path 2001 -- connecting chamber 2003 -- first connecting port 2004 -- first control chamber 211 -- third connecting port 2007 -- inlet chamber 2005 -- annular chamber 401 -- outlet 12 -- outlet chamber 13. (The last sentence appears to be a separate, unrelated statement.) Figure 13 , 14 As shown, one end of the pressure relief channel 11 is connected to the cavity 1, and the other end is connected to the functional valve body 150. The functional valve body 150 is also provided with a confluence channel that connects to the water outlet cavity 13. The pressure relief channel 11 is opened and closed by sliding the third shaft 120, that is, the opening and closing of the pressure relief channel 11 and the confluence channel are controlled. When it is opened, the pressure is released, and the water flow is along the cavity 1 -- pressure relief channel 11 -- functional valve body 150 -- confluence channel -- water outlet cavity 13 to release pressure.

[0117] This embodiment provides a water path switching method, which achieves switching of water output effect based on the water outlet device of this embodiment. The water path switching method includes:

[0118] Step S1: Turn on the overhead shower and allow water to enter through the water inlet mechanism 20;

[0119] Step S2: Water enters the water outlet device. When water enters the first control chamber of the first mechanism 200 and the second control chamber of the second mechanism 300, under the action of water pressure, the first shaft and the second shaft move away from the water circuit switching mechanism 110. At this time, water exits from one chamber 1 of the water distribution mechanism, realizing a water outlet effect. This water outlet effect is defined as the first water outlet effect (first water outlet state).

[0120] Step S3: Turn off the water outlet device that is in the hot water state and select the appropriate option based on whether the duration exceeds t:

[0121] If the flow exceeds t, the first control chamber 211 and the second control chamber 311 drain water through the first drain valve 240 and the second control valve 340, respectively. First, the first control chamber 211 drains water, and under the action of the first elastic element 230, the first shaft 220 of the first mechanism 200 slides towards the water circuit switching mechanism 110. Approximately when the water is drained, the water circuit switching mechanism 110 is driven to rotate in the forward direction (clockwise or counterclockwise) and drive the water distribution mechanism to switch to the second water outlet state (closing the pilot valve of the first water outlet state and opening the pilot valve of the second water outlet state). The second control chamber 311 drains water, and... Under the action of the second elastic element 330, the second shaft 320 of the second mechanism 300 slides towards the water circuit switching mechanism 110. Approximately when the water is drained, it drives the water circuit switching mechanism 110 to rotate in the opposite direction and drives the water distribution mechanism to move back to the first water outlet state (closing the pilot valve of the second water outlet state and opening the pilot valve of the first water outlet state), and then executes step S1. Since the water draining time of the second control chamber 311 is later than the water draining time of the first control chamber 211, the first shaft 220 first drives the water circuit switching mechanism 110 to rotate in the forward direction, and then the second shaft 320 drives the water circuit switching mechanism 110 to rotate in the reverse direction.

[0122] If the time limit is not exceeded, the first control chamber 211 and the second control chamber 311 drain water through the first drain valve 240 and the second control valve 340 respectively. The first control chamber 211 drains water and, under the action of the first elastic element 230, the first shaft 220 of the first mechanism 200 slides toward the water path switching mechanism 110, driving the water path switching mechanism 110 to rotate in the forward direction and driving the water distribution mechanism to switch to the second water outlet effect. (At this time, the water in the second control chamber 311 is not completely drained, and the second shaft does not slide or does not slide to drive the water path switching mechanism to reverse.) Then, step S1 is executed.

[0123] When the water outlet device is turned off while the water is in the hot state, the instantaneous switching mechanism and the delayed switching mechanism sequentially drive the water circuit switching mechanism 110, causing the water circuit switching mechanism 110 to rotate in two opposite directions at the same angle to maintain the state before the water was turned off. This ensures that the water outlet state before the water was turned off can be maintained when the water is turned on again, providing convenience for the user.

[0124] When the water outlet device in the hot water state is turned off and then quickly turned on again, the delay switching mechanism 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 drives the water circuit switching mechanism 110 to rotate a certain angle, controlling one chamber to turn off the water and the other chamber to open the water, thus achieving the switching of the water outlet effect.

[0125] This embodiment uses two water output effects as an example for illustration, but it is not limited to this; three or four water output effects can also be applied.

[0126] Example 2

[0127] This embodiment provides a water outlet device. The difference between this embodiment and Embodiment 1 is that the specific water distribution method of the water distribution mechanism is different.

[0128] Reference Figure 15 and Figure 16 The water outlet device provided in this embodiment does not have the pressure chamber of Embodiment 1. The water distribution body has a water flow channel 14, which is connected to the water inlet mechanism 20. The water flow channel 14 is connected to multiple water outlets 12, and each water outlet 12 corresponds to a 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 move. 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 third axis 120. By moving the water distribution mechanism along this straight line, the two water outlets 12 are opened alternately, thereby achieving the switching of water outlet effects.

[0129] The water distribution mechanism includes a water distribution valve assembly, the structure of which can be the same as in Embodiment 1. A third shaft 120 is disposed in the water distribution space. The rotation of the water path switching mechanism 110 can drive the third shaft 120 to perform a linear motion along its axial direction within the water flow channel 14. This is achieved through the third shaft... Figure 15 and Figure 16 The two positions shown are switched to alternately open the water outlet 12, thereby switching the water output effect. This embodiment uses two water outlets as an example for explanation, but it is not limited to this. Multiple water outlets can be set at intervals along the sliding direction. The water path switching mechanism 110 is provided with corresponding multi-level protrusions. The outer diameters of the multi-level protrusions are not equal. Then, the multi-level protrusions control different positions at the third axis, so that water is output from the water outlets at different positions, thereby switching different effects.

[0130] Example 3

[0131] This embodiment provides a water outlet device. The difference between this embodiment and Embodiment 1 is that the water outlet device only has a first mechanism. The water distribution mechanism includes multiple pilot valves. Each pilot valve is equipped with a sliding third shaft and a main flow channel 403. The opening or closing of the pilot valve controls the connection or disconnection of the water inlet mechanism and the main flow channel 403 of the water outlet device, i.e., controls the connection or disconnection of the annular cavity and the water outlet. The sliding of the third shaft controls the opening and closing of the pilot valves. At least one of the water path switching mechanisms rotates, causing the third shaft to slide. The selected pilot valve opens, connecting its main flow channel and the water inlet mechanism, allowing water to flow from its main flow channel, outlet, and water outlet cavity. The ratchet of the water path switching mechanism only has a first circumferential ratchet tooth. The first shaft of the first mechanism engages with the first circumferential ratchet tooth, and the third shaft is connected to the water path switching mechanism. The structure and connection of the pilot valve, the first mechanism, and the third shaft can be referred to Embodiment 1.

[0132] Example 4

[0133] This embodiment provides a driving device. The difference between this embodiment and Embodiment 1 is that the water circuit switching mechanism is rotatable and therefore a movable mechanism in this embodiment. The driving device includes a water inlet mechanism, a movable mechanism, a first mechanism, and a second mechanism. The first and second mechanisms can respectively drive the movable mechanism to operate. Both the first and second mechanisms can connect the water inlet mechanism. When the water inlet mechanism shuts off the water and the duration exceeds t, the first mechanism first drives the movable mechanism to rotate forward, and then the second mechanism drives the movable mechanism to rotate in reverse. When the water is shut off and the duration does not exceed t, only the first mechanism drives the movable mechanism to rotate forward. The rotation of the movable mechanism or its rotation followed by a reset can be controlled by the on / off time of the water inlet mechanism. The structure of the movable mechanism, the first mechanism, and the second mechanism can be referred to in Embodiments 1 and 3.

[0134] If necessary, a sliding third axis may also be included. The movable mechanism is provided with multiple control slots along the circumference. The rotation of the movable mechanism drives the third axis to slide through the multiple control slots. The sliding of the third axis can be controlled by the on and off time of the water inlet mechanism. The sliding control of the third axis can be referred to Embodiment 1.
