[0003] This application claims priority to Chinese Patent Application No. 202511016641.0, filed on July 23, 2025, entitled “Shower Equipment”, the entire contents of which are incorporated herein by reference. Technical Field

[0004] This application relates to the field of shower equipment technology, and in particular to a switching valve and a shower equipment. Background Technology

[0005] Currently, combination shower heads that use remote water path switching technology, consisting of an overhead shower and a head shower, typically only have the function of spraying water from the overhead shower and water from the head shower, lacking a function to stop the water flow, making their functionality relatively limited. Simply replacing the overhead shower with a handheld shower head that has a water stop function will only cause the handheld shower head to stop spraying water, while the overhead shower will continue to spray water normally, failing to achieve the desired water stop function. Summary of the Invention

[0006] According to various embodiments of this application, a switching valve and a shower device are provided.

[0007] On one hand, a switching valve is provided, including a switching valve seat with a water distribution chamber. The switching valve seat is provided with a first outlet, a first water passage chamber and a second water passage chamber that can communicate with the water distribution chamber. Water flow from the water distribution chamber can flow out from the first outlet through the second water passage chamber. A movable switching valve core is provided inside the switching valve seat. The switching valve core is provided with a first sealing part and a second sealing part. A second sealing surface that can maintain a sealing fit with the second sealing part is formed on the inner circumference of the second water passage chamber. A first sealing surface that can maintain a sealing fit with the first sealing part is formed on the inner circumference of the first water passage chamber. The cross-sectional area of ​​the first sealing part is smaller than the cross-sectional area of ​​the second sealing part. It also includes a flow port. When the second sealing part is in contact with the second sealing surface, water flow from the water distribution chamber can flow out from the first outlet through the flow port.

[0008] In one embodiment, the first outlet is also connected to a control valve that can pass water. The control valve has a state when water flows at a small flow rate. When water flows at a small flow rate, the control valve forms a pause water channel that can pass water. The water passage area of ​​the pause water channel is larger than the water passage area of ​​the outlet, so that the water flow can drive the switching valve core to move, and the second sealing part can release the sealing engagement with the second sealing surface.

[0009] In one embodiment, the control valve also has a non-water discharge state and a normal water discharge state; when the control valve is in the non-water discharge state, the water flow can drive the switching valve core to move, releasing the sealing fit between the first sealing part and the first sealing surface.

[0010] When the control valve is in normal water discharge state, the water flow can drive the switching valve core to move, releasing the sealing fit between the second sealing part and the second sealing surface.

[0011] In one embodiment, when the first sealing part is sealed to the first sealing surface, the second sealing part can be sealed to the second sealing surface, or the second sealing part can be unsealed to the second sealing surface.

[0073] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. 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

[0074] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0075] 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.

[0076] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0077] 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 this application. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0078] Referring to Figures 1 to 7 of the specification, a switching valve 300 includes a switching valve seat 301 with a water distribution chamber 3010. The switching valve seat is provided with a first outlet 3013, a first water passage chamber 3011 and a second water passage chamber 3012 that can communicate with the water distribution chamber. Water from the water distribution chamber can flow out from the first outlet through the second water passage chamber. A movable switching valve core 302 is provided inside the switching valve seat. The switching valve core can also be a plug, which is used to control whether water flows out of the two water passage chambers. The switching valve core is provided with a second sealing part M2 and a first sealing part M1. A second sealing surface K21 that can maintain a sealing fit with the second sealing part is formed on the inner circumference of the second water passage chamber. A first sealing surface K11 that can maintain a sealing fit with the first sealing part is formed on the inner circumference of the first water passage chamber. The first sealing surface and the first sealing part cooperate to form a first water passage K1. The second sealing surface and the second sealing part cooperate to form a second water passage K2. The cross-sectional area S2 of the second sealing part is larger than the cross-sectional area S1 of the first sealing part. The switching valve also includes a flow port K3. When the second sealing part is engaged with the second sealing surface, the water flow in the water distribution chamber can flow out from the first outlet through the flow port.

[0079] In some embodiments, the first outlet is also connected to a control valve F that allows water to pass through. The control valve has three states: a water-stopped state (i.e., low-flow water passage), a normal water-outflow state (i.e., high-flow water passage), and a no-water-outflow state. When the control valve is in the low-flow water passage state, it forms a water-stopped water passage F01. The cross-sectional area S4 of the water-stopped water passage is larger than the cross-sectional area S3 of the outlet, so that the water flow can drive the switching valve core to move and disengage the second sealing part from the second sealing surface. At this time, due to the difference in cross-sectional area, the water flow at the outlet cannot meet the flow requirements of the downstream end. In order to compensate for the downstream water flow, the water flow will cause the switching valve core to move (it can make a small displacement from the sealed state), causing the second sealing part to slightly separate from the second sealing surface, forming a water passage gap K22, which compensates for the difference in water passage area between S4 and S3, and prevents the water flow from disengaging the first sealing part from the first sealing surface after the second sealing part and the second sealing surface have sealed together, thus preventing a mis-switching situation.

[0080] It should be explained that the first water outlet can be connected to both the water distribution chamber and the outside world. Here, the outside world refers to the part other than the switching valve, which may include other water outlet devices, such as a top spray shower. When the first water outlet is open, the water flow in the water distribution chamber flows through the first water outlet to the top spray shower and is sprayed into the atmosphere by the top spray shower; or, the first water outlet can directly serve as a drain outlet connected to the atmosphere, that is, the water flow in the water distribution chamber is directly discharged into the atmosphere through the first water outlet.

[0081] It is understood that the control valve and the switching valve are connected. In some embodiments, the control valve can be connected to the switching valve seat via a connecting pipe, and the interior of the connecting pipe forms a fluid cavity between the switching valve and the control valve.

[0082] In one application, the control valve can have two switching shafts F02. The one on the left in the diagram is used to switch between high and low flow rates, while the one on the right is used to cut off the water flow. In another application, the control valve can be a combination of button control and toggle control. The button is used to cut off the water flow, and the toggle is used to switch between high and low flow rates, or vice versa. In yet another application, the control valve can be configured to cut off the water flow and switch between high and low flow rates by rotating the toggle.

[0083] In some embodiments, the control valve also has a non-discharge state and a normal discharge state; when the control valve is in the non-discharge state, the water flow can drive the switching valve core to move, releasing the sealing fit between the first sealing part and the first sealing surface. At this time, the second sealing part and the second sealing surface are in a sealing fit state; when the control valve is in the normal discharge state, the water flow can drive the switching valve core to move, releasing the sealing fit between the second sealing part and the second sealing surface, while the first sealing part and the first sealing surface are in a sealing fit state.

[0084] In some embodiments, when the first sealing part is sealed to the first sealing surface, the second sealing part can be sealed to the second sealing surface, or the second sealing part can be unsealed to the second sealing surface. In use, the two sealing parts cannot be released at the same time, that is, the second water outlet and the first water outlet cannot pass water at the same time.

[0085] In some embodiments, the flow port can be provided on at least one of the switching valve seat and the switching valve core.

[0086] In some embodiments, the flow port is provided on the second sealing part and also includes a pin 303. The pin can be inserted into the flow port, which can ensure that the scale remaining in the flow port can be automatically cleaned during use, ensuring smooth water flow. At this time, S3 should be the minimum cross-sectional area that the first water passage hole can allow water to flow through after deducting the space occupied by the pin.

[0087] Referring to Figure 8, in some embodiments, a water passage 3014 is also provided inside the switching valve seat, and the flow port is located at the switching valve seat at the rear end of the second water outlet, so that the water distribution chamber can flow out from the first water outlet through the water passage and the flow port.

[0088] In a specific application, the first water outlet can be connected to the second water outlet device, and the first water inlet can be connected to the first water outlet device; the second water outlet device can be a handheld shower head, and the first water outlet device can be an overhead shower head; the two water outlet devices are not shown in the figure; the switching valve in this application can also be integrated into the first water outlet device.

[0089] In some embodiments, the water flow from the first outlet can flow out through the second outlet device after passing through a control valve, which can be integrated into the second outlet device; the water flow in the water distribution chamber can maintain communication with the first outlet through the flow port.

[0090] More specifically, this application describes a remote switching structure, mainly comprising: a switching valve seat with a second sealing surface and a first sealing surface, both arranged along the axis of the switching valve seat, the two sealing surfaces having a certain length on the axis; and a switching valve core with a second sealing part and a first sealing part, which can respectively seal and cooperate with the second sealing surface and the first sealing surface of the switching valve seat. When the sealing part of the switching valve core moves on the sealing surface of the switching valve seat, the sealing part and sealing surface at the corresponding position are always in a sealed state. It also includes a control valve that cooperates with the switching module. Wherein: 1. The cross-sectional area of ​​the sealing part S2 > S1; 2. The flow cross-sectional area S3 < the flow cross-sectional area S4; 3. The flow cross-sectional area S3 is less than 5 square millimeters. The two ends of the switching valve seat are fluidly connected to a second water outlet device and a first water outlet device, respectively. A control valve is provided during the connection to the second water outlet device, and the control valve can switch between three states: 1. High flow rate; 2. Low flow rate; 3. No water (i.e., no water flow).

[0091] In this application: when the control valve is in the normal water outlet state, the water pressure on the second sealing part of the switching valve core is greater than the water pressure on the first sealing part, causing the switching valve core to move towards the second sealing part. The second sealing part and the second sealing surface disengage from their sealing contact, and the water in the water distribution chamber flows to the second water outlet device.

[0092] During the switching valve core's movement, there may be a situation where both the second sealing part and the first sealing part of the switching valve seat and the switching valve core are in a sealed engagement state, at which point neither of the two water outlet devices will discharge water.

[0093] When the control valve is in a low-flow state, since S4>S3, most of the water flowing through S3 will be discharged through S4. The switching valve core will not be in the middle state. At this time, the water pressure on the second sealing part of the switching valve core is greater than the water pressure on the first sealing part. The switching valve core moves towards the second sealing part, so that the second sealing part and the second sealing surface are slightly separated from the sealing. The water flow in the water distribution chamber is slightly transmitted to the second water outlet device.

[0094] When the control valve is closed and water is not flowing, and the switching valve is in the first outlet position, the water in the water distribution chamber no longer flows with the second outlet. With the flow port connected, the water pressure on both sides of the water distribution chamber and the switching valve seat is balanced by the water pressure on both sides of the first outlet, and the water pressure on both sides of the second sealing part of the switching valve core cancels each other out. At this time, there is pressure only in the first sealing part of the switching valve core. Under the action of the water pressure on the first sealing part, the valve core moves towards the first sealing part, causing the first sealing part and the first sealing surface to disengage and seal. The water in the water distribution chamber flows to the first outlet device, and the second outlet device does not flow.

[0095] Please refer to Figure 9, which is a structural schematic diagram of a shower device provided in an embodiment of this application. Figure 10 is a partially enlarged schematic diagram of point A in Figure 9, and Figure 11 is a partially enlarged schematic diagram of point B in Figure 9. The shower device may be provided with a fluid inlet R, and the shower device may include: a first water outlet device 100, a second water outlet device 200, a switching valve 300, and a control valve F.

[0096] The first water outlet device 100 is equipped with a first fluid outlet t1. For example, the first water outlet device 100 may be a stationary shower.

[0097] The second water outlet device 200 is equipped with a second fluid outlet t2. For example, the second water outlet device 200 can be a handheld shower. The first water outlet device 100 and the second water outlet device 200 are connected by a connecting pipe L.

[0098] A switching valve 300 is located downstream of the fluid inlet R of the shower equipment. The switching valve 300 is used to control the flow of fluid from the fluid inlet R to at least one of the first fluid outlet t1 and the second fluid outlet t2.

[0099] The control valve F is located in the second water outlet device 200 and is configured to control the second fluid 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 fluid outlet is less than that of the normal water outlet state.

[0100] The switching valve 300 responds to different outlet states of the control valve F and switches to different states so that the first fluid outlet t1 is in different outlet states.

[0101] When the control valve F is in the water-stopped state, the control valve F is configured to connect the water-stopped channel with the second fluid outlet t2, and the switching valve 300 responds to this state to control the first fluid outlet t1 to be in the non-water-discharging state.

[0102] By installing a switching valve 300 downstream of the fluid inlet R of the shower equipment and a control valve F inside the second water outlet device 200, the control valve F can control the second fluid outlet t2 of the second water outlet device 200 to be in different water outlet states, and in conjunction with the switching valve 300, control the first fluid outlet t1 of the first water outlet device 100 to be in different water outlet states. That is, when the second water outlet device 200 is in a paused water outlet state (small flow or dripping state, not a complete cutoff), the first fluid outlet t1 of the first water outlet device 100 is in a no-water-supply state; when the second water outlet device 200 is in a normal water outlet state, the first fluid outlet t1 of the first water outlet device 100 is in a no-water-supply state; when the second water outlet device 200 is not discharging water, the first fluid outlet t1 of the first water outlet device 100 is in a water-supply state. This enriches the functions of the shower equipment and greatly facilitates the user's flexibility and convenience.

[0103] In summary, this application provides a shower device that may include: a first water outlet device, a second water outlet device, a switching valve, and a control valve. By installing a switching valve downstream of the fluid inlet of the shower device and a control valve within the second water outlet device, the control valve can control the second fluid outlet of the second water outlet device to be in different water outlet states, and in conjunction with the switching valve, control the first fluid outlet 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, not complete shut-off), the first fluid outlet of the first water outlet device is in a no-water-supply state; when the second water outlet device is in a normal water outlet state, the first fluid outlet of the first water outlet device is in a no-water-supply state; and when the second water outlet device is not discharging water, the first fluid outlet of the first water outlet device is in a water-supply state. This enriches the functionality of the shower device and greatly enhances the user's flexibility and convenience.

[0104] In some embodiments, please refer to Figures 10, 12, and 13. Figure 12 is a partial structural schematic diagram of a first water outlet device provided in an embodiment of this application, and Figure 13 is a partial structural schematic diagram of a second water outlet device provided in an embodiment of this application. The second water outlet device 200 is equipped with an operating part for switching the water outlet state of the control valve F. The switching valve 300 includes: a switching valve seat 301, and a switching valve core 302 movably disposed in the switching valve seat 301. The switching valve 300 is equipped with a first water outlet K1 that can communicate with a first fluid outlet t1, and a second water outlet K2 that can communicate with a second fluid outlet t2. When the control valve F is operated to switch the water outlet state, the fluid pressure in the fluid cavity between the switching valve 300 and the control valve F is changed. This fluid pressure change directly or indirectly drives the movement of the switching valve core 302 and changes the on / off state of at least one of the first water outlet K1 and the second water outlet K2.

[0105] The switching valve core 302 is equipped with a flow port 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.

[0106] In some embodiments, the switching valve core 302 has a first sealing portion M1 and a second sealing portion M2 disposed opposite to each other, wherein the cross-sectional area of ​​the first sealing portion M1 is smaller than the cross-sectional area of ​​the second sealing portion M2. The inner wall of the switching valve seat 301 cooperates with the first sealing portion M1 to form a first water passage K1, and the inner wall of the switching valve seat 301 cooperates with the second sealing portion M2 to form a second water passage K2. A through hole is formed on the second sealing portion M2 to form a flow passage K3.

[0107] 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 300 and the control valve F, due to the difference in area between the first sealing part M1 and the second sealing part M2, the switching valve core 302 will move to change the on / off state of at least one of the first water inlet K1 and the second water inlet K2 when the pressure on the first sealing part M1 and the second sealing part M2 is different. Here, when the second water outlet device 200 is in the normal water outlet state, the first water inlet K1 is disconnected and the second water inlet K2 is open; when the second water outlet device 200 is in the water stop state, the first water inlet K1 is disconnected and the second water inlet K2 is disconnected from the control valve F or connected with a flow coefficient less than or equal to the flow coefficient of the water stop channel; when the second water outlet device 200 is in the no-water-out state, the second water inlet K2 is disconnected and the first water inlet K1 is open.

[0108] It should be noted that the water passage area of ​​the pause water channel can be larger than the water passage area of ​​the flow outlet K3.

[0109] In some embodiments, as shown in Figures 11, 13, 14, and 15, Figure 14 is a partial structural schematic diagram of another first water outlet device provided in an embodiment of this application, and Figure 15 is a partial structural schematic diagram of another second water outlet device provided in an embodiment of this application. The control valve F includes: a valve seat 400 and a water distribution valve portion 500 cooperating with the valve seat 400; one of the valve seat 400 and the water distribution valve portion 500 is provided with a water passage hole, and the corresponding other is provided with a water through hole T3. A 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 400 and the water distribution valve portion 500 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.

[0110] 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 400 and the water distribution valve section 500 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.

[0111] For example, referring to Figure 15, after the water distribution valve 500 moves relative to the valve seat 400 to align and connect the normal water passage T2 with the water passage T3, the switching valve core 302 opens the second water passage K2 to seal the first water passage K1. Alternatively, after the water distribution valve 500 moves relative to the valve seat 400 to connect the pause water passage T1 with the water passage T3, the switching valve core 302 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 500 moves relative to the valve seat 400 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.

[0112] For example, referring to Figures 10, 14 and 15, after the water distribution valve 500 moves relative to the valve seat 400 to align and connect the normal water passage T2 with the water passage T3, since the cross-sectional area of ​​the second sealing part M2 is larger than the cross-sectional area of ​​the first sealing part M1, the water pressure on the left side of the second sealing part M2 is greater than the water pressure on the first sealing part M1. Therefore, the switching valve core 302 moves to the right to seal the first water passage K1 through the first sealing part M1, and the second water outlet device 200 outputs normal water, while the first water outlet device does not output water.

[0113] As shown in Figures 12 and 13, after the water distribution valve 500 moves relative to the valve seat 400 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 port K3. Since the water flowing to the second water outlet device 200 through the flow port K3 is drained by the pause water passage, the water pressure on the right side of the second sealing part M2 is almost zero or much less than that on the left side. Because the cross-sectional area of ​​the second sealing part M2 is larger than that of the first sealing part M1, the water pressure on the left side of the second sealing part M2 is greater than that on the first sealing part M1, causing the switching valve core 302 to move to the right. The second sealing part M2 and the second water passage K2 slightly separate to form a water passage gap, so that the first sealing part M1 seals the first water passage K1. The second water outlet device 200 discharges paused water, while the first water outlet device 100 does not discharge water.

[0114] As shown in Figures 10, 11, and 12, when the water distribution valve 500 moves relative to the valve seat 400, causing the pause water passage T1 and the normal water passage T2 to be disconnected from the water passage T3, the water flow to the second water outlet device 200 is blocked. Under the connection of the flow port K3, the forces on both sides of the second sealing part M2 cancel each other out, while the right side of the first sealing part M1 is subjected to water pressure. Therefore, the switching valve core 302 moves to the left to open the first water passage K1. At this time, the first water outlet device 100 outputs water, while the second water outlet device 200 does not output water.

[0115] In some embodiments of this application, referring to FIG16, FIG16 is a partial structural cross-sectional view of a second water outlet device provided in an embodiment of this application. The operating part is a push button 501, the valve seat 400 has a sliding cavity Q1, the water distribution valve part 500 is movably disposed in the sliding cavity Q1, and the side wall of the second water outlet device 200 is provided with a sliding groove N1. The push button 501 is slidably disposed in the sliding groove N1 and connected to the water distribution valve part 500 to control the movement of the water distribution valve part 500. In this way, by pushing the push button 501 to drive the water distribution valve part 500 to move in the sliding cavity Q1, the water passage hole and the water flow hole T3 can be selectively opened and closed, or the opening and closing between the normal water passage hole T2, the paused water passage hole T1 and the water flow hole T3 can be controlled.

[0116] In this case, push-button 501 control is used, which is ergonomic and has a simple program. Simply push the button to the desired water flow mode to achieve the desired result in one step. Here, the water distribution valve 500 can be equipped with a pause water flow hole T1 and a normal water flow hole T2, and the valve seat 400 can be equipped with a flow passage hole T3; alternatively, the water distribution valve 500 can be equipped with a flow passage hole T3, and the valve seat 400 can be equipped with a pause water flow hole T1 and a normal water flow hole T2.

[0117] For example, as shown in Figure 16, the valve seat 400 may have a water passage hole T3, and the water distribution valve portion 500 may have a pause water passage hole T1 and a normal water passage hole T2 arranged along the sliding direction of the water distribution valve portion 500. In one implementation in some embodiments, the outer wall of the water distribution valve portion 500 may have two first sealing grooves N2 distributed on both sides of the pause water passage hole T1, and the water distribution valve portion 500 may include a first sealing member 503 installed in the first sealing groove N2, and the normal water passage hole T2 may be located at the bottom of the water distribution valve portion 500.

[0118] In another implementation in some embodiments, please refer to FIG17, which is a partial structural cross-sectional view of another second water outlet device provided in an embodiment of this application. The inner wall of the valve seat 400 may have a second sealing groove N3, a third sealing groove N4, and a fourth sealing groove N5 arranged along the extension direction of the sliding cavity Q1, and further includes: a second sealing member 504 installed in the second sealing groove N3, a third sealing member 505 installed in the third sealing groove N4, and a fourth sealing member 506 installed in the fourth sealing groove N5. The water passage hole T3 in the valve seat 400 is distributed between the second sealing groove N3 and the third sealing groove N4. The water distribution valve part 500 may have a pause water passage hole T1 and a normal water passage hole T2 arranged along the sliding direction of the water distribution valve part 500. For example, the above-mentioned sealants may be annular sealing rings.

[0119] In some embodiments, please refer to FIG18, which is a partial structural cross-sectional view of another second water outlet device provided in this application embodiment. The control valve F may include: a valve seat 400, a normal water flow valve core F1, a water stop valve core F2, a reset valve core F3, and a stabilizing element F4. The stabilizing element F4 can reciprocate in one direction to engage or disengage with the aforementioned valve cores. The operating unit can be connected to the normal water flow 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 flow valve core F1, the water stop valve core F2, and the reset valve core F3.

[0120] When the operating unit operates, the normal flow valve core F1 cooperates with the stabilizing component F4. The normal flow valve core F1 cooperates with the valve seat 400 to form a normal flow channel, which is connected to the second fluid outlet t2, thus keeping the second fluid outlet t2 in a normal water outflow state. When the operating unit operates, the stop flow valve core F2 cooperates with the stabilizing component F4. The stop flow valve core F2 cooperates with the valve seat 400 to form a stop flow channel, which is connected to the second fluid outlet t2, thus keeping the second fluid outlet t2 in a stopped flow state.

[0121] 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 element F4. This disconnects the normal water flow channel and the pause water flow channel from the second fluid outlet t2, placing the second fluid outlet t2 in a non-discharging state. As shown in Figure 18, the reset valve core F3 and the stabilizing element F4 can be optionally configured so that the reset valve core F3 is not locked in place by the stabilizing element F4 after movement. Here, the first fluid outlet t1 is connected to the first water inlet K1.

[0122] As shown in Figure 18, the operating unit includes a top spray button 514, a pause button 515, and a shower button 516 arranged sequentially. One end of the top spray button 514 can be connected to the reset valve core F3, one end of the pause button 515 can be connected to the pause water valve core F2, and one end of the shower button 516 can be connected to the normal water flow valve core F1. The second water outlet device 200 may have a first connection hole (not shown in the figure) slidably connected to the top spray button 514, a second connection hole slidably connected to the pause button 515, and a third connection hole slidably connected to the shower button 516.

[0123] The valve seat 400 also has an inlet chamber Q2 and an outlet chamber Q3 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 400 and are located within the inlet chamber Q2. For example, the valve seat 400 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, normal water passage T2, and normal water valve core of the valve seat cooperate to form a normal water passage; the inlet chamber, transition hole k2, pause water passage T1, and pause water valve core F2 of the valve seat cooperate to form a pause water passage.

[0124] Pressing the top spray button 514 causes the stabilizer F4 to move in a direction perpendicular to the movement direction of the top spray button 514, 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 515 causes the stabilizer F4 to move in a direction perpendicular to the movement direction of the pause button 515, 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 is sealed at the support hole k1. Pressing the shower button 516 causes the stabilizer F4 to move in a direction perpendicular to the movement direction of the shower button 516, 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.

[0125] For example, the operating unit also includes: a first spring 511, a second spring 512, and a third spring 513. The two ends of the first spring 511 can respectively abut against the valve seat 400 and the end of the reset valve core F3 away from the top spray button 514; the two ends of the second spring 512 can respectively abut against the valve seat 400 and the end of the pause water valve core F2 away from the pause button 515; the two ends of the third spring 513 can respectively abut against the valve seat 400 and the end of the normal water flow valve core F1 away from the shower head button 516. The stabilizing component F4 includes: a stabilizing component body 509 and a stabilizing component spring 510. The two ends of the stabilizing component spring 510 can respectively abut against the valve seat 400 and the stabilizing component body 509.

[0126] For example, the stabilizer body 509 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 509 may also have a first locking portion disposed adjacent to the second abutting portion and a second locking portion disposed adjacent to the third abutting portion.

[0127] 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.

[0128] For example, pressing the top spray button 514 causes the first end D1 of the reset valve core F3 to abut against the first contact portion of the stabilizer body 509, pushing the stabilizer body 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, 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. Thus, under the elastic force of the second spring 512, 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 513, 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 511 allows the first end D1 of the reset valve core F3 to return to its initial position.

[0129] Pressing the pause button causes the first end D2 of the pause water valve core F2 to abut against the second contact part of the stabilizer body, pushing the stabilizer body to move. This causes the third locking part on the first end D2 of the pause water valve core F2 to engage with the first locking part of the stabilizer body, opening the pause water passage. Meanwhile, under the elastic force of the third spring 513, the first end D3 of the normal water valve core F1 is sealed to the normal water passage.

[0130] Pressing the handheld shower button causes the first end D3 of the normal water flow valve core F1 to abut against the third contact part of the stabilizer body, pushing the stabilizer body to move. This causes the fourth locking part on the first end D3 of the normal water flow valve core F1 to engage with the second locking part of the stabilizer body, opening the normal water flow hole. Meanwhile, the third locking part on the first end D2 of the pause water valve core F2 disengages from the first locking part of the stabilizer body and returns to its initial position under the action of the second spring 512, sealing the transition hole k2 and cutting off the pause water flow hole.

[0131] In other implementations, referring to FIG19, FIG19 is a partial structural cross-sectional view of another second water outlet device provided in an embodiment of the present application. The operating part can be a knob 508, and the side wall of the second water outlet device 200 can have a mounting hole that is rotatably connected to the knob 508. The water distribution valve part 500 can be a water distribution plate 507, which is disposed opposite to the valve seat 400 and can have a pause water flow hole T1 and a normal water flow hole T2, or a water passage hole T3.

[0132] For example, the water distribution plate 507 may have a pause water passage hole T1 and a normal water passage hole T2, and the valve seat 400 may have a water passage hole T3. Thus, by rotating the knob 508, the water distribution plate 507 can be rotated so that the pause water passage hole T1 or the normal water passage hole T2 on the water distribution plate 507 aligns and connects with the water passage hole T3 on the valve seat 400. Alternatively, the water distribution plate 507 may have a water passage hole T3, and the valve seat 400 may have a pause water passage hole T1 and a normal water passage hole T2. Thus, by rotating the knob 508, the water distribution plate 507 can be rotated so that the water passage hole T3 on the water distribution plate 507 aligns and connects with the pause water passage hole T1 or the normal water passage hole T2 on the valve seat 400.

[0133] In this embodiment, the first water outlet device 100 is a fixed shower, and the second water outlet device 200 is a handheld shower. The second water outlet device 200 is detachably mounted on the first water outlet device 100. This detachable connection allows users to meet two different usage needs: either the second water outlet device 200 can be mounted on the first water outlet device for support, or the two can be separated for use in different scenarios.

[0134] As shown in Figure 9, the second water outlet device 200 can have a shower head and a handle that are interconnected. The valve seat 400 and the water distribution valve 500 can both be installed inside the handle. This installation of the valve seat 400 and the water distribution valve 500 inside the handle fully utilizes the internal space of the second water outlet device 200, ensuring that shower outlet modules of different sizes can be used with the shower head, thus improving the flexibility of shower usage.

[0135] For example, please refer to Figure 20, which is a schematic diagram of another shower device provided in an embodiment of this application. The first water outlet device 100 includes a mounting part 101a, and the second water outlet device 200 is provided with a mating part 101b corresponding to the mounting part. The mounting part 101a and the mating part 101b are connected by at least one of a snap-fit ​​structure and a magnetic attraction structure.

[0136] In some embodiments, please refer to Figures 20, 21, 22, and 23. Figure 21 is a partial structural schematic diagram of another first water outlet device provided in an embodiment of this application; Figure 22 is a partial structural schematic diagram of another second water outlet device provided in an embodiment of this application; and Figure 23 is an assembly diagram of the structures shown in Figures 21 and 22. In one connection method, the mounting part 101a has a fixed slide groove c1, a slider buckle A1, and an elastic member A2. The slider buckle A1 is slidably mounted in the fixed slide groove c1, and both ends of the elastic member A2 abut against the side wall of the fixed slide groove c1 and one end of the slider buckle A1, respectively. The mating part 101b has a groove c2 that engages with the other end of the slider buckle A1.

[0137] In another connection method, the mounting part 101a is provided with at least one of a magnet and a magnetic guide 102, and the mating part 101b is provided with at least one of a magnetic guide and a magnet 202 that form a magnetic attraction with the mounting part 101a. In this way, the two can be connected by magnetic attraction, which is convenient for installation and disassembly.

[0138] The snap-fit ​​structure in the embodiments of Figures 20 and 22 can be used in conjunction with magnetic connection.

[0139] In this embodiment of the application, the second water outlet device 200 is provided with a water outlet module 203, which has at least one spray mode, and the control valve F includes a spray switching valve for selecting the spray mode.

[0140] For example, please refer to Figures 24 and 25. Figure 24 is a partially exploded view of a second water outlet device provided in an embodiment of this application, and Figure 25 is another exploded view of the second water outlet device shown in Figure 24. The spray switching valve includes: a fixed bracket 204, a cup 205, and a first elastic member 206. The water outlet module 203 has multiple shower head inlets b1. The fixed bracket 204 is located between the water outlet module 203 and the inner wall of the second water outlet device 200. The cup 205 is fixed on the fixed bracket 204 and contacts the water outlet module 203, and has water passage holes b2 corresponding to the multiple shower head inlets b1. The two ends of the first elastic member 206 abut against the cup 205 and the fixed bracket 204, respectively.

[0141] For example, the fixed bracket 204 can rotate relative to the second water outlet device 200 so that the water inlet b2 is connected to each shower head inlet b1, or the water outlet module 203 can rotate relative to the second water outlet device 200 so that each shower head inlet b1 is connected to the water inlet b2.

[0142] In this application, the fixed bracket 204 may have a fastening mounting groove b3, and the cup 205 may be fitted into the fastening mounting groove b3, with the outer wall of the cup 205 sealingly connected to the inner wall of the fastening mounting groove b3. Thus, after the cup 205 is installed in the fastening mounting groove b3 of the fixed bracket 204, the cup 205 expands when water is passed through it, allowing the outer wall of the cup 205 to make tight contact with the inner wall of the fastening mounting groove b3, ensuring a sealed connection between the cup 205 and the fixed bracket 204. Simultaneously, the first elastic member 206 located on one side of the cup 205 can bring the cup 205 into tight contact with the water outlet module 203, ensuring a sealed connection between the cup 205 and the water outlet module 203.
