Description

Technical Field

[0001] This application relates to the field of shower equipment technology, and in particular to a shower device. Background Technology

[0002] Existing shower systems using remote switching technology do not have a function to stop the water flow (a function that is currently in high demand among users). If a second water outlet device with a water stop function is simply added to work with it, the second water outlet device will only stop the water flow, while the first water outlet device will continue to flow normally. This fails to meet the need for water stoppage, resulting in a single function of the shower system and inconvenience for users. Utility Model Content

[0003] This application provides a shower device. It solves the problem that existing shower devices have limited functionality, causing inconvenience for users. The technical solution is as follows:

[0008] The switching valve responds to different water outlet states of the control valve and switches to different states so that the first outlet is in different water outlet states;

[0009] When the control valve is in the water interruption state, the control valve is configured such that the water interruption channel is connected to the liquid outlet of the control valve, and the switching valve responds to this state by controlling the first liquid outlet to be in the no-water state.

[0011] The switching valve includes: a switching valve seat and a switching valve core movably disposed within the switching valve seat. The switching valve has a first water inlet that can communicate with a first liquid outlet and a second water inlet that can communicate with a control valve. When the control valve is operated to switch the water outlet state, it changes the fluid pressure in the fluid cavity between the switching valve and the control valve. This change in fluid pressure directly or indirectly drives the movement of the switching valve core and changes the on / off state of the first water inlet and / or the second water inlet.

[0012] The switching valve core is equipped with a flow passage, which is always connected to the control valve.

The pause water valve core cooperates with the valve seat to form a pause water channel, and the pause water channel is connected to the liquid outlet of the control valve, so that the liquid outlet of the control valve is in a paused water discharge state.

[0025] The operating unit operates the reset valve core to disengage both the normal water flow valve core and the pause water flow valve core from the stabilizing component.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0060] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0061] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0062] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0063] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 This is a schematic diagram of the structure of a shower device provided in an embodiment of this application. Figure 2 yes Figure 1 The cross-sectional view of the shower unit shown is as follows. Figure 3 yes Figure 2 A magnified view of a portion at point A. Figure 4 yes Figure 2 A partially enlarged schematic diagram at point B. The shower device may include: a water pipe 10, a first water outlet device 20, a second water outlet device 30, a switching valve 40, and a control valve F.

[0064] The water pipe 10 has a water inlet end, and the first water outlet device 20 and the second water outlet device 30 are located at opposite ends of the water inlet end, respectively. The first water outlet device 20 has a first liquid outlet t1. Here, the first water outlet device 20 can be a fixed shower, and the second water outlet device 30 can be a handheld shower.

[0065] The switching valve 40 is installed inside the water pipe 10 and near the water inlet. The switching valve 40 is used to control the flow of liquid from the water inlet to the first outlet t1 and / or the control valve F.

[0066] The control valve F is installed at the bottom of the water pipe 10 and has a control valve outlet t. The control valve F is configured to control the control valve outlet t to be in different water discharge states, including at least a no-discharge state, a normal water discharge state, and a water-stopped state when the water flow rate at the control valve outlet is less than that in the normal water discharge state. Here, the control valve outlet t can be connected to the second water discharge device 30.

[0067] Among them, the switching valve 40 responds to different water outlet states of the control valve F and switches to different states so that the first outlet t1 is in different water outlet states.

[0068] When the control valve F is in the water interruption state, the control valve F is configured to connect the water interruption channel with the control valve outlet t, and the switching valve 40 responds to this state to control the first outlet t1 to be in the no-water state.

[0069] In this embodiment, a switching valve 40 is installed near the inlet end of the water pipe 10, and a control valve F is installed at the bottom of the water pipe 10. The control valve F can control the outlet t of the control valve to be in different water outlet states, and works with the switching valve 40 to control the first outlet t1 of the first water outlet device 20 to be in different water outlet states. That is, when the outlet t of the control valve is in a paused water outlet state (small flow or dripping state, not a complete cut-off), the first outlet of the first water outlet device is in a no-water-supply state; when the outlet t of the control valve is in a normal water outlet state, the first outlet t1 of the first water outlet device 20 is in a no-water-supply state; and when the outlet t of the control valve is in a no-water-supply state, the first outlet t1 of the first water outlet device 20 is in a water-supply state. In addition, the first water outlet device 20 is close to the water channel supplying the water to the first water outlet device 20, eliminating the need for a complex water intake mechanism and reducing costs.

[0070] In summary, this application provides a shower device that may include: a water pipe, a first water outlet device, a second water outlet device, a switching valve, and a control valve. By installing a switching valve near the inlet end of the water pipe and a control valve at the bottom of the water pipe, the control valve can control the outlet of the control valve to be in different water outlet states, and in conjunction with the switching valve, control the first outlet of the first water outlet device to be in different water outlet states. That is, ultimately, when the outlet of the control valve is in a paused water outlet state (small flow or dripping, not complete shut-off), the first outlet of the first water outlet device is in a no-water-supply state; when the outlet of the control valve is in a normal water outlet state, the first outlet of the first water outlet device is in a no-water-supply state; and when the outlet of the control valve is not discharging water, the first outlet of the first water outlet device is in a water-supply state. Furthermore, the first water outlet device is close to the water channel supplying the first water outlet device, eliminating the need for a complex water intake mechanism and reducing costs.

[0071] Optional, please refer to Figure 2 and Figure 5 , Figure 5 This is a partial structural schematic diagram of a shower device provided in an embodiment of this application. The bottom of the water pipe may be equipped with an operating part for switching the water outlet device of the control valve. The switching valve 40 may include: a switching valve seat 41, and a switching valve core 42 movably disposed within the switching valve seat 41. The switching valve 40 has a first water outlet K1 that can communicate with a first liquid outlet t1, and a second water outlet K2 that can communicate with the control valve F. When the control valve F is operated to switch the water outlet state, it changes the fluid pressure in the fluid cavity between the switching valve 40 and the control valve F. This change in fluid pressure directly or indirectly drives the movement of the switching valve core 42 and changes the on / off state of the first water outlet K1 and / or the second water outlet K2.

[0072] The switching valve core 42 is equipped with a flow passage K3, which is always connected to the control valve F. When the control valve F is in the water interruption state, the second water outlet K2 is disconnected from the control valve F or connected in a state where the flow coefficient is less than or equal to the flow coefficient of the water interruption channel.

[0073] Please refer to the following in this application: Figure 4 , Figure 5 and Figure 6 , Figure 6 This is a cross-sectional view of a switching valve core provided in an embodiment of this application. The switching valve core 42 may have a first sealing portion 421 and a second sealing portion 422 disposed opposite to each other. The first sealing portion 421 can cooperate with the inner wall of the switching valve seat 41 to form a first water passage K1, and the second sealing portion 422 can cooperate with the inner wall of the switching valve seat 41 to form a second water passage K2. The cross-sectional area S1 of the first sealing portion 421 is smaller than the cross-sectional area S2 of the second sealing portion 422, and the second sealing portion 422 may have a through hole forming a flow passage K3.

[0074] In this situation, when the control valve F is operated to switch the water outlet state, changing the fluid pressure in the fluid cavity between the switching valve 40 and the control valve F, due to the difference in area between the first sealing part 421 and the second sealing part 422, the switching valve core 42 will move to change the on / off state of the first water outlet K1 and / or the second water outlet K2 when the pressure on the first sealing part 421 and the second sealing part 422 is different. Here, when the control valve outlet t is in the normal water outlet state, the first water outlet K1 is disconnected and the second water outlet K2 is open; when the control valve outlet t is in the water pause state, the first water outlet K1 is disconnected and the second water outlet K2 is disconnected from the control valve F or connected with a flow coefficient less than or equal to the flow coefficient of the paused water channel; when the control valve outlet t is in the no-water-out state, the second water outlet K2 is disconnected and the first water outlet K1 is open.

[0075] Here, the water passage area of ​​the pause water channel is larger than the water passage area of ​​the flow hole K3.

[0076] In the embodiments of this application, such as Figure 6 As shown, the switching valve 40 may further include a pin 43, which can be inserted into the flow passage K3 and clearance-fitted with it. This ensures that scale remaining in the flow passage K3 can be automatically cleaned during use, guaranteeing smooth water flow. The water passage area of ​​the flow passage K3 should be the minimum cross-sectional area that allows water to flow through after deducting the space occupied by the pin 43.

[0077] Optional, please refer to Figure 4 , Figure 7 and Figure 8 , Figure 7 This is a schematic diagram illustrating the cooperation effect between a valve seat and a water distribution valve according to an embodiment of this application. Figure 8 This is a partial structural schematic diagram of another shower device provided in an embodiment of this application. The control valve F may include: a valve seat 50 and a water distribution valve part 60 that cooperates with the valve seat 50; one of the valve seat 50 and the water distribution valve part 60 is provided with a water passage hole, and the corresponding other is provided with a water through hole T3. The portion of the water passage hole overlaps with the water through hole T3 to form a pause water passage hole, or, if one of the valve seat 50 and the water distribution valve part 60 is provided with a pause water passage hole T1, then the component provided with the pause water passage hole T1 is also provided with a normal water passage hole T2. Here, the water through hole T3 communicates with the pause water passage hole T1 to form a paused water channel.

[0078] Specifically, when the control valve F is in the normal water outlet state, the water inlet hole and the water passage hole T3 are connected; when the control valve F is in the non-water outlet state, the water passage hole T3 is disconnected from both the water inlet hole and the pause water inlet hole T1. It should be noted that when the valve seat 50 and the water distribution valve section 60 are equipped with the pause water inlet hole T1, the normal water inlet hole T2, and the water passage hole T3, the normal water inlet hole T2 is connected to the water passage hole T3 when the control valve F is in the normal water outlet state.

[0079] Example, reference Figure 4 After the water distribution valve section 60 moves relative to the valve seat 50 to align and connect the normal water passage T2 with the water passage T3, the switching valve core 42 opens the second water passage K2 to seal the first water passage K1. Alternatively, after the water distribution valve section 60 moves relative to the valve seat 50 to connect the pause water passage T1 with the water passage T3, the switching valve core 42 seals the first water passage K1, and the second water passage K2 is disconnected from the control valve F or connected with a flow coefficient less than or equal to the flow coefficient of the pause water passage. Alternatively, after the water distribution valve section 60 moves relative to the valve seat 50 to de-connect both the pause water passage T1 and the water passage T2 with the water passage T3, the switching valve core opens the first water passage K1 and closes the second water passage K2.

[0080] For example, after the water distribution valve section 60 moves relative to the valve seat 50 to align and connect the normal water passage T2 and the water flow passage T3, refer to Figure 5 Since the cross-sectional area of ​​the second sealing part 422 is larger than that of the first sealing part 421, the water pressure on the upper side of the second sealing part 422 is greater than that on the first sealing part 421. Therefore, the switching valve core 42 moves downward and seals the first water outlet K1 through the first sealing part 421, and the control valve outlet t discharges normal water, while the first water outlet device 20 does not discharge water.

[0081] like Figure 7 and Figure 8As shown, after the water distribution valve 60 moves relative to the valve seat 50 to align and connect the pause water passage T1 with the water passage T3, the water passage area of ​​the pause water passage T1 is larger than that of the flow passage K3. Since the water flowing to the control valve F through the flow passage K3 is drained by the pause water passage, the water pressure on the lower side of the second sealing part 422 is almost zero or much less than the water pressure on the upper side. Because the cross-sectional area of ​​the second sealing part 422 is larger than that of the first sealing part 421, the water pressure on the upper side of the second sealing part 422 is greater than that on the first sealing part 421, causing the switching valve core 42 to move downward. The second sealing part 422 and the second water passage K2 are slightly separated to form a water passage gap, so that the first sealing part 421 seals the first water passage K1, the control valve outlet t discharges paused water, and the first water outlet device 20 does not discharge water.

[0082] Please refer to Figure 2 , Figure 9 and Figure 10 , Figure 9 This is a schematic diagram illustrating the cooperation effect between another valve seat and water distribution valve provided in an embodiment of this application. Figure 10 This is a partial structural schematic diagram of another shower device provided in the embodiments of this application. After the water distribution valve part 60 moves relative to the valve seat 50, causing the pause water passage T1 and the normal water passage T2 to be disconnected from the water passage T3, the control valve outlet t leading to the second water outlet device 30 is not flowing. Under the connection of the flow passage K3, the forces on both sides of the second sealing part 422 cancel each other out, while the lower side of the first sealing part 421 is subjected to water pressure. Therefore, the switching valve core 42 moves upward to conduct the first water passage K1. At this time, the first water outlet device 20 outputs water, while the second water outlet device 30 does not output water.

[0083] There are several possible implementation methods for combining the water distribution valve section and the operating section. The following embodiments of this application illustrate two possible implementation methods as examples:

[0084] The first optional implementation method, such as Figure 9 As shown, the operating part can be a knob 62, the water distribution valve part 60 can be a water distribution plate 61, and the side wall of the water pipe 10 can have a mounting hole for rotatable connection with the knob 62. The water distribution plate 61 is disposed opposite to the valve seat 50 and can have a pause water flow hole T1 and a normal water flow hole T2, or a water passage hole T3.

[0085] For example, the water distribution plate 61 may have a pause water passage hole T1 and a normal water passage hole T2, and the valve seat 50 may have a water passage hole T3. Thus, by rotating the knob 62, the water distribution plate 61 can be rotated so that the pause water passage hole T1 or the normal water passage hole T2 on the water distribution plate 61 aligns and connects with the water passage hole T3 on the valve seat 50. Alternatively, the water distribution plate 61 may have a water passage hole T3, and the valve seat 50 may have a pause water passage hole T1 and a normal water passage hole T2. Thus, by rotating the knob 62, the water distribution plate 61 can be rotated so that the water passage hole T3 on the water distribution plate 61 aligns and connects with the pause water passage hole T1 or the normal water passage hole T2 on the valve seat 50.

[0086] For the second optional implementation method, please refer to... Figure 11 , Figure 12 and Figure 13 , Figure 11 This is a partial structural schematic diagram of another shower device provided in an embodiment of this application. Figure 12 yes Figure 11 The diagram shown illustrates the effect of the shower device in one state. Figure 13 yes Figure 11 The diagram shows the effect of the shower device in another state. The operating part can be a push button 63, and the valve seat 50 can have a sliding cavity Q, the extension direction of which can be parallel to the axis of the water pipe 10. The water distribution valve part 60 is movably disposed in the sliding cavity Q, and the side wall of the water pipe 10 can have a sliding groove C that is slidably connected to the push button 63. The push button 63 is slidably operated in the sliding groove C and connected to the water distribution valve part 60 to control the movement of the water distribution valve part 60. The water distribution valve part 60 can be located in the sliding cavity Q and has a pause water flow hole T1 and a normal water flow hole T2, or a water passage hole T3.

[0087] For example, the water distribution valve section 60 may have a pause water passage hole T1 and a normal water passage hole T2, and the valve seat 50 may have a through water hole T3. Thus, by pushing the button 63, the water distribution valve section moves within the sliding cavity Q of the valve seat 50, aligning and connecting the pause water passage hole T1 or the normal water passage hole T2 on the water distribution valve section 60 with the through water hole T3 on the valve seat 50. Alternatively, the water distribution valve section 60 may have a through water hole T3, and the valve seat 50 may have a pause water passage hole T1 and a normal water passage hole T2. Thus, by pushing the button 63, the water distribution valve section 60 moves within the sliding cavity Q of the valve seat 50, aligning and connecting the through water hole T3 on the water distribution valve section 60 with the pause water passage hole T1 or the normal water passage hole T2 on the valve seat 50.

[0088] Please refer to Figure 14 , Figure 15 and Figure 16 , Figure 14 This is a partial structural schematic diagram of a shower device provided in another embodiment of this application. Figure 15 yes Figure 14 A schematic diagram illustrating the effect of the proposed shower device in one state. Figure 16 yes Figure 14 The diagram shows the effect of the shower device in another state. The control valve F may include: valve seat 50, normal water flow valve core F1, water stop valve core F2, and reset valve core F3, as well as a stabilizing element F4, which can reciprocate in one direction to engage or disengage with the valve cores.

[0089] The operating unit is connected to the normal water supply valve core F1, the water stop valve core F2, and the reset valve core F3 respectively, and the operating unit can independently control the normal water supply valve core F1, the water stop valve core F2, or the reset valve core F3.

[0090] The normal water flow valve core F1 of the operating unit cooperates with the stabilizing component F4. The normal water flow valve core F1 cooperates with the valve seat to form a normal water flow channel, and the normal water flow channel is connected to the liquid outlet t of the control valve, so that the liquid outlet t of the control valve is in a normal water flow state.

[0091] The operation unit operates the pause water valve core F2 and the stabilizer F4 to cooperate. The pause water valve core F2 cooperates with the valve seat to form a pause water channel, and the pause water channel is connected to the control valve outlet t, so that the control valve outlet t is in a paused water discharge state.

[0092] The operating unit operates the reset valve core F3, causing both the normal water flow valve core F1 and the pause water flow valve core F2 to disengage from the stabilizing component F4. This disconnects the normal water flow channel and the pause water flow channel from the control valve outlet t, thus placing the control valve outlet t in a non-discharging state. Figure 14 As shown, the reset valve core F3 and the stabilizer F4 can be optionally configured so that the reset valve core F3 will not be locked in place by the stabilizer F4 after it moves. Here, the first liquid outlet t1 is connected to the first water inlet K1.

[0093] like Figure 14 As shown, the operating unit includes a top spray button 70, a pause button 71, and a shower head button 72 arranged sequentially. One end of the top spray button 70 can be connected to the reset valve core F3, one end of the pause button 71 can be connected to the pause water valve core F2, and one end of the shower head button 72 can be connected to the normal water flow valve core F1. The water pipe 10 may have a first connecting hole (not shown in the figure) slidably connected to the top spray button 70, a second connecting hole slidably connected to the pause button 71, and a third connecting hole slidably connected to the shower head button 72.

[0094] The valve seat 50 also has an inlet chamber Q1 and an outlet chamber Q2 connected by a pause water passage T1 or a normal water passage T2. The first end D1 of the reset valve core F3, the first end D2 of the pause water valve core F2, and the first end D3 of the normal water valve core F1 all pass through the valve seat 50 and are located within the inlet chamber Q1. For example, the valve seat 50 may have a support hole k1 that mates with the first end D1 of the reset valve core F3, a transition hole k2 that mates with the first end D2 of the pause water valve core F2, a pause water passage T1 located downstream of the transition hole k2, and a normal water passage T2 that mates with the first end D3 of the normal water valve core F1. It should be noted that the inlet chamber Q1, the normal water passage T2, and the normal water valve core F1 of the valve seat 50 can cooperate to form a normal water passage; the inlet chamber Q1, the transition hole k2, the pause water passage T1, and the pause water valve core F2 of the valve seat 50 can cooperate to form a pause water passage.

[0095] Pressing the top spray button 70 causes the stabilizer F4 to move in a direction perpendicular to the movement direction of the top spray button 70, so that the first end D2 of the pause water valve core F2 is sealed to the transition hole k2 and the first end D3 of the normal water valve core F1 is sealed to the normal water passage T2. Pressing the pause button 71 causes the stabilizer F4 to move in a direction perpendicular to the movement direction of the pause button 71, and after the first end D2 of the pause water valve core F2 engages with the stabilizer F4, the pause water channel is opened, the first end D3 of the normal water valve core F1 is sealed to the normal water passage T2, and the first end D1 of the reset valve core F3 abuts against the support hole k1. Pressing the shower button 72 causes the stabilizer F4 to move in a direction perpendicular to the movement direction of the shower button 72, and after the first end D3 of the normal water valve core F1 engages with the stabilizer F4, the normal water passage is opened, and the first end D2 of the pause water valve core F2 is sealed at the transition hole k2, so that the pause water passage T1 is not open.

[0096] For example, the operating unit may further include: a first spring 67, a second spring 68, and a third spring 69. The two ends of the first spring 67 can respectively abut against the valve seat 50 and the end of the reset valve core F3 away from the top spray button 70; the two ends of the second spring 68 can respectively abut against the valve seat 50 and the end of the pause valve core F2 away from the pause button 71; the two ends of the third spring 69 can respectively abut against the valve seat 50 and the end of the normal flow valve core F1 away from the shower head button 72. The stabilizing component F4 includes: a stabilizing component body 65 and a stabilizing component spring 66. The two ends of the stabilizing component spring 66 can respectively abut against the valve seat 50 and the stabilizing component body 65.

[0097] Please refer to the following in this application: Figure 17 , Figure 17This is a schematic diagram of the structure of a stabilizer body provided in an embodiment of this application. For example, the stabilizer body 65 may have a first abutting portion that mates with the first end D1 of the reset valve core F3, a second abutting portion that mates with the first end D2 of the stop water valve core F2, and a third abutting portion that mates with the first end D3 of the normal water flow valve core F1. The stabilizer body 65 may also have a first locking portion adjacent to the second abutting portion and a second locking portion adjacent to the third abutting portion.

[0098] The first end D2 of the pause valve core F2 may have a third engaging portion that mates with the first engaging portion, and the first end D3 of the normal flow valve core F1 may have a fourth engaging portion that mates with the second engaging portion. Here, the first abutting portion, the second abutting portion, and the third abutting portion may all have a first abutting slope, and the first end D1 of the reset valve core F3, the first end D2 of the pause valve core F2, and the first end D3 of the normal flow valve core F1 may all have a second abutting slope that mates with the first abutting slope.

[0099] For example, pressing the top spray button 70 causes the first end D1 of the reset valve core F3 to abut against the first contact portion of the stabilizer body 65, pushing the stabilizer body 65 to move. This causes the third locking portion on the first end D2 of the pause water valve core F2 to disengage from the first locking portion of the stabilizer body 65, and the fourth locking portion on the first end D3 of the normal water valve core F1 to disengage from the second locking portion of the stabilizer body 65. Thus, under the elastic force of the second spring 68, the first end D2 of the pause water valve core F2 is sealed to the pause water passage T1, cutting off the transition hole k2. Under the elastic force of the third spring 69, the first end D3 of the normal water valve core F1 is sealed to the normal water passage. The elastic force of the first spring 67 allows the first end D1 of the reset valve core F3 to return to its initial position.

[0100] Pressing the pause button 71 causes the first end D2 of the pause water valve core F2 to abut against the second contact portion of the stabilizer body 65, pushing the stabilizer body 65 to move. This causes the third locking portion on the first end D2 of the pause water valve core F2 to engage with the first locking portion of the stabilizer body 65, opening the pause water passage. Meanwhile, under the elastic force of the third spring 69, the first end D3 of the normal water valve core F1 is sealed to the normal water passage.

[0101] Pressing the handheld shower button 72 causes the first end D3 of the normal water flow valve core F1 to abut against the third contact portion of the stabilizer body 65, pushing the stabilizer body 65 to move. This causes the fourth locking portion on the first end D3 of the normal water flow valve core F1 to engage with the second locking portion of the stabilizer body 65, opening the normal water flow hole. Meanwhile, the third locking portion on the first end D2 of the pause water valve core F2 disengages from the first locking portion of the stabilizer body 65 and returns to its initial position under the action of the second spring 68, sealing the transition hole k2 and cutting off the pause water flow hole. Here, after moving, the stabilizer body 65 moves in the opposite direction under the action of the stabilizer spring 66.

[0102] Optional, such as Figure 1 As shown, the shower device also includes: an upper pipe 80 connected to the top of the water pipe 10 and a hose 90 connected to the control valve outlet at the bottom of the water pipe 10. The first water outlet device 20 can be connected to the water pipe 10 through the upper pipe 80, and the second water outlet device 30 can be connected to the water pipe 10 through the hose 90.

[0103] In this embodiment, a slide 12 may be provided on the outer side of the water pipe 10, and a mating part 121 may be provided on the slide 12 that can be detachably engaged with the second water outlet device 30. In this way, the mating part 121 facilitates the support and use of the second water outlet device 30.

[0104] This application also provides another shower device, please refer to... Figure 18 , Figure 19 , Figure 20 and Figure 21 , Figure 18 This is a schematic diagram of another shower device provided in an embodiment of this application. Figure 19 yes Figure 18 The diagram shows a cross-sectional view of a second water outlet device in a shower apparatus. Figure 20 yes Figure 18 A cross-sectional view of another second water outlet device of the shower unit is shown. Figure 21 yes Figure 20 A cross-sectional view of another second water outlet device of the shower apparatus is shown. The shower apparatus may include: a water pipe 10, a first water outlet device 20, a second water outlet device 30, a switching valve 40, and a control valve F.

[0105] The water pipe 10 has an inlet end, and a first water outlet device 20 and a second water outlet device 30 are located at opposite ends of the inlet end. The first water outlet device 20 has a first outlet t1, and the second water outlet device 30 has a second outlet t2. Here, the first water outlet device 20 is a fixed shower, and the second water outlet device 30 is a handheld shower. A switching valve 40 is installed inside the water pipe 10 and near the inlet end. The switching valve 40 is used to control the flow of liquid from the inlet end to the first outlet t1 and / or the second outlet t2.

[0106] The control valve F is installed in the second water outlet device 30 and is configured to control the second outlet t2 to be in different water outlet states, including at least the no water outlet state, the normal water outlet state, and the water stop state when the water flow rate of the second outlet is less than that of the normal water outlet state.

[0107] Specifically, the switching valve 40 switches to different states in response to different water outlet states of the control valve F, so that the first outlet t1 is in different water outlet states. When the control valve F is in the water stop state, the control valve F is configured to connect the water stop channel with the second outlet t2, and the switching valve 40 responds to this state to control the first outlet t1 to be in the no-water state.

[0108] In this embodiment, a switching valve 40 is installed near the inlet end of the water pipe 10, and a control valve F is installed in the second water outlet device. The control valve F can control the second fluid outlet t2 of the second water outlet device to be in different water outlet states, and cooperates with the switching valve to control the first liquid outlet t1 of the first water outlet device to be in different water outlet states. That is, when the second water outlet device is in a paused water outlet state (small flow or dripping state, not a complete cut-off), the first liquid outlet t1 of the first water outlet device 20 is in a no-water-supply state; when the second water outlet device 30 is in a normal water outlet state, the first liquid outlet t1 of the first water outlet device 20 is in a no-water-supply state; when the second water outlet device 30 is in a no-water-supply state, the first liquid outlet t1 of the first water outlet device 20 is in a water-supply state.
