[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.
[0045] Combine the following Figures 1 to 13 , describing an embodiment of the present application.
[0046] According to an embodiment of the present application, on the one hand, a water outlet component is provided, such as Figure 1 As shown, it includes a first cylinder body 2, a first piston 1, a liquid discharge pipe 3, a blocking member and a one-way valve. The one-way valve can be a duckbill valve 83.
[0047] The first cylinder body 2 is provided with a first liquid port 21 and a second liquid port 22. The first piston 1 is slidably disposed in the first cylinder body 2 to form a piston cylinder, and the first piston 1 can slide along the first cylinder body 2 between a first position and a second position. When the first piston 1 slides to the first position, the first liquid port 21 and the second liquid port 22 are respectively located on the outside of the two ends of the first piston 1, so that the first liquid port 21 is disconnected from the second liquid port 22. When the first piston 1 slides to the second position, the first piston 1 is located on the side of the second liquid port 22 away from the first liquid port 21, so that the first liquid port 21 and the second liquid port 22 are located on the outside of the same end of the first piston 1, and at this time, the first liquid port 21 is connected to the second liquid port 22.
[0048] The blocking member can slide between a first state and a second state. When the blocking member slides to the first state, the blocking member blocks the drain pipe 3, so that the liquid cannot flow from the first liquid port 21 to the drain pipe 3 for discharge. When the blocking member slides to the second state, the blocking member leaves the drain pipe 3, so that the drain pipe 3 is open, and at this time the drain pipe 3 is connected to the first liquid port 21, and the liquid can flow from the first liquid port 21 to the drain pipe 3 for discharge.
[0049] With this arrangement, when the water outlet assembly is used, Figure 1 As shown, the blocking member is normally in the second state, and the first piston 1 is in the first position. The second liquid port 22 is connected to the liquid outlet cavity 81 of the bathing device, so that water can flow from the second liquid port 22 to the liquid outlet cavity 81 of the bathing device, and the liquid outlet cavity 81 is connected to the liquid outlet head 82 of the bathing device through a one-way valve, so that the one-way valve is unidirectional in the direction of flow from the liquid outlet cavity 81 to the liquid outlet head 82, so that water in the liquid outlet cavity 81 can flow to the liquid outlet head 82 through the one-way valve, and gas cannot flow from the liquid outlet head 82 through the one-way valve to the liquid outlet cavity 81 and then flow to the second liquid port 22.
[0050] like Figure 2 As shown, during the process of the blocking member sliding to the first state, water is discharged into the first cylinder body 2 through the first liquid port 21, and the water can push the first piston 1 to slide along the first cylinder body 2 to the second position. Until the first piston 1 slides to the second position, the first liquid port 21 and the second liquid port 22 are connected, so that the water in the first cylinder body 2 can flow out to the liquid outlet cavity 81 through the second liquid port 22, and then be diverted to each liquid outlet head 82 for discharge, thereby realizing the conventional water spraying function of the bathing device.
[0051] When you stop using it, Figure 1 As shown, the first liquid port 21 stops taking in water, the blocking member slides from the first state to the second state, the drain pipe 3 is connected, water can flow from the first liquid port 21 to the drain pipe 3 for discharge, and the first piston 1 slides to the first position.
[0052] During the sliding of the first piston 1, before the second liquid port 22 is still connected to the first liquid port 21, part of the water in the liquid outlet cavity is sucked into the first cylinder body 2 and flows to the drain pipe 3 through the first liquid port 21 for discharge. When the first piston 1 is initially located between the second liquid port 22 and the first liquid port 21, until the first piston 1 slides to the first position, at least part of the water in the liquid outlet cavity is sucked to the side of the first piston 1 in the first cylinder body 2 away from the first liquid port 21. Due to the presence of the one-way valve, negative pressure is formed in the liquid outlet cavity 81, and the one-way valve is pressed and closed, so that water cannot flow out through the one-way valve, ensuring that the water remaining in the liquid outlet cavity 81 will not drip from the liquid outlet head 82, achieving an immediate stop-and-turn effect, and preventing water from continuously dripping to generate noise or dripping on the user's body, causing trouble to the user.
[0053] like Fig.11 As shown, the first piston 1 may include a moving block 11 and a rubber ring 12 . The rubber ring 12 is installed in a mounting groove on the moving block 11 . When the first piston 1 is installed in the first cylinder body 2 , the rubber ring 12 fits against the inner wall of the first cylinder body 2 .
[0054] As an optional embodiment, Figure 1 and Figure 2As shown, the water outlet assembly also includes a first elastic member 4. The first end of the first elastic member 4 is connected to the first piston 1, and the second end of the second elastic member 7 is connected to the first cylinder 2. Under normal conditions, the first piston 1 is located at the first position. When in use, when the water flow and water pressure drive the first piston 1 to slide to the second position, the first elastic member 4 generates elastic deformation. At this time, under the action of the first elastic member 4, the first piston 1 has a tendency to slide to the first position. After the driving force on the first piston 1 is cancelled, the first elastic member 4 rebounds, and the first piston 1 can slide from the second position to the first position.
[0055] The first elastic member 4 may be a spring, and a mounting column 23 is provided in the first cylinder body 2. The first end of the first elastic member 4 is connected to the end of the first piston 1 close to the second liquid port 22, and the second end is sleeved on the mounting column 23. In this way, when the first piston 1 is driven to slide to the second position, the first elastic member 4 is compressed. After the driving force on the first piston 1 is canceled, the first elastic member 4 rebounds and pushes the first piston 1 to slide from the second position to the first position.
[0056] Specifically, after water enters the first cylinder 2 from the first liquid port 21, it pushes the first piston 1 to slide from the first position to the second position, until the first piston 1 slides to the second position, the first piston 1 slides to the side of the second liquid port 22 away from the first liquid port 21, and the first elastic member 4 is compressed. The water in the first cylinder 2 can be discharged to the liquid outlet cavity 81 through the second liquid port 22, and then divided to each liquid outlet head 82 for discharge, realizing a conventional water spraying function.
[0057] After the first liquid port 21 stops inflowing water, the first piston 1 is no longer pushed by the water. The blocking member is slid to the second state, and the drain pipe 3 is open. The first elastic member 4 rebounds and pushes the first piston 1 to slide from the second position to the first position. In this process, the water on the side of the first piston 1 close to the first liquid port 21 is pushed by the first piston 1 and flows from the first liquid port 21 to the drain pipe 3 for discharge.
[0058] With such arrangement, the first piston 1 is automatically pushed to slide from the second position to the first position after water is cut off, without manual operation, and is more convenient to use.
[0059] As an optional embodiment, Figure 1 and Figure 2 As shown, the water outlet assembly further includes a second cylinder body 6, which is provided with a third liquid port 61 and a fourth liquid port 62. The fourth liquid port 62 is connected to the first liquid port 21, and one end of the connecting pipe 9 extends into the second cylinder body 6 and is connected to the fourth liquid port 62, and further connected to the first liquid port 21.
[0060] The blocking member includes a second piston 5, which is slidably disposed in the second cylinder body 6 to form a piston cylinder, and the second piston 5 is always located between the third liquid port 61 and the fourth liquid port 62. That is, the second piston 5 can slide along the second cylinder body 6 in the area between the third liquid port 61 and the fourth liquid port 62, thereby sliding between the third position and the fourth position. When the second piston 5 slides to the fourth position, the second piston 5 abuts against one end of the discharge pipe 3 extending into the second cylinder body 6 and blocks the discharge pipe 3, and the blocking member is in the first state; when the second piston 5 slides to the third position, the second piston 5 leaves one end of the discharge pipe 3 extending into the second cylinder body 6, so that the discharge port is conductive, and the blocking member is in the second state.
[0061] For the second piston 5, its first end is close to the third liquid port 61, and its second end is close to the fourth liquid port 62. When the pressure on the first end of the second piston 5 is greater than the pressure on the second end, water can flow from the first end of the second piston 5 through the second piston 5 to the second end.
[0062] The second piston 5 can be a one-way piston cup, which is a special sealing element widely used in gas or liquid transmission systems. Fig.12 As shown, the second piston 5 includes a piston body 51 and a flange 52 obliquely arranged on the piston body, and the inclination direction of the flange 52 is the direction in which the second piston 5 slides from the third position to the fourth position. The flange 52 can be deformed and fits with the inner wall of the second cylinder body 6 under normal conditions. When the water pressure at the first end of the second piston 5 is greater than the water pressure at the second end, the flange 52 is deformed and leaves the inner wall of the second cylinder body 6 to form a gap 521, so that water can flow from the first end of the second piston 5 to the second end of the second piston 5 through the gap 521.
[0063] When the second piston 5 slides to the fourth position, the second piston 5 abuts against one end of the discharge pipe 3 extending into the second cylinder body 6 and closes the discharge pipe 3. As water continues to enter, the second piston 5 cannot continue to slide, resulting in the water pressure at the first end of the second piston 5 being greater than that at the second end. The flange 52 is deformed and leaves the inner wall of the second cylinder body 6 to form a gap 521, so that water can pass through the gap 521 between the flange 52 and the inner wall of the second cylinder body 6.
[0064] In this way, when the water outlet assembly is used, the blocking member is in the second state, the first piston 1 is in the first position, the second piston 5 is in the third position, and the second liquid port 22 is connected to the liquid outlet chamber 81 of the bathing device, so that water can flow from the second liquid port 22 to the liquid outlet chamber 81 of the bathing device.
[0065] Water enters the chamber located outside the first end of the second piston 5 in the second cylinder 6 through the third liquid port 61. As the water continues to enter, it pushes the second piston 5 to slide toward the fourth position. When the second piston 5 slides to the fourth position, the second piston 5 abuts against the drain pipe 3 and seals the end of the drain pipe 3 extending into the second cylinder 6, that is, the blocking member slides to the first state. At this time, water continues to enter, but the second piston 5 cannot continue to slide, resulting in the water pressure on the first end of the second piston 5 being greater than the water pressure on the second end, causing the flange 52 to deform and leave the inner wall of the second cylinder 6 to form a gap 521, so that water can flow from the first end of the second piston 5 to the second end of the second piston 5 through the gap 521. Because the drain pipe 3 is blocked by the second piston 5, water can flow out from the fourth liquid port 62 to the first liquid port 21.
[0066] Water is discharged into the first cylinder body 2 through the first liquid port 21, pushing the first piston 1 to slide along the first cylinder body 2 to the second position, until the first piston 1 slides to the second position, and the first piston 1 slides to the side of the second liquid port 22 away from the first liquid port 21. At this time, the first liquid port 21 and the second liquid port 22 are connected, so that the water in the first cylinder body 2 can be discharged to the liquid outlet cavity 81 through the second liquid port 22, and then diverted to each liquid outlet head 82 of the bathing device for discharge, thereby realizing a conventional water spraying function.
[0067] When the device is not in use, water stops entering the third liquid port 61. The second piston 5 is slid to the third position to open the liquid discharge pipe 3, and the first piston 1 is slid to the first position.
[0068] During the sliding process of the first piston 1, before the second liquid port 22 is still connected to the first liquid port 21, part of the water in the liquid outlet chamber 81 is sucked into the first cylinder body 2 and flows to the liquid discharge pipe 3 through the first liquid port 21 for discharge. When the first piston 1 is initially located between the second liquid port 22 and the first liquid port 21, until the first piston 1 slides to the first position, at least part of the water in the liquid outlet chamber 81 is sucked to the side of the first piston 1 in the first cylinder body 2 away from the first liquid port 21; the water on the side of the first piston 1 away from the second liquid port 22 flows to the liquid discharge pipe 3 through the first liquid port 21 for discharge.
[0069] When the first piston 1 slides from the second position to the first position, due to the presence of the one-way valve, negative pressure is formed in the liquid outlet chamber 81, and the one-way valve is pressed closed, so that water cannot flow out through the one-way valve, thereby ensuring that the water remaining in the liquid outlet chamber 81 will not drip from the liquid outlet head 82, thereby preventing water from continuously dripping and generating noise or dripping on the user's body, causing trouble to the user.
[0070] As an optional embodiment, Figure 1 and Figure 2As shown, the water outlet assembly further includes: a second elastic member 7. The first end of the second elastic member 7 is connected to the second piston 5, and the second end of the second elastic member 7 is connected to the second cylinder 6. Normally, the second piston 5 is located at the third position. When the second piston 5 is driven to slide to the fourth position, the second elastic member 7 generates elastic deformation. At this time, under the action of the second elastic member 7, the second piston 5 has a tendency to slide to the third position; after the driving force on the second piston 5 is canceled, the second elastic member 7 rebounds, which can push the second piston 5 to slide from the fourth position to the third position.
[0071] The second elastic member 7 may be a spring. The first end of the second elastic member 7 is connected to the end of the second piston 5 close to the fourth liquid port 62, and the second end of the second elastic member 7 is sleeved on the discharge pipe 3 and connected to the inner wall of the second cylinder 6. In this way, when the second piston 5 is driven to slide to the fourth position, the second elastic member 7 is compressed until the second piston 5 slides to the fourth position, the second piston 5 abuts against the discharge pipe 3 and blocks the discharge pipe 3, and the blocking member is in the first state; after the driving force on the second piston 5 is canceled, the second elastic member 7 rebounds and pushes the second piston 5 to slide from the fourth position to the third position, at which time the second piston 5 leaves the discharge pipe 3, the discharge pipe 3 is connected, and the blocking member is in the second state.
[0072] Specifically, after water enters the second cylinder body 6 from the third liquid port 61, it pushes the second piston 5 to slide to the fourth position, and the second elastic member 7 is compressed until the second piston 5 slides to the fourth position, at which time the second piston 5 blocks the discharge pipe 3. As water continues to enter, the second piston 5 cannot continue to slide, resulting in the water pressure at the first end of the second piston 5 being greater than that at the second end. The flange 52 is deformed and leaves the inner wall of the second cylinder body 6 to form a gap 521, so that water can pass through the gap 521 between the flange 52 and the inner wall of the second cylinder body 6, thereby being able to flow to the fourth liquid port 62.
[0073] After the third liquid port 61 stops taking in water, the second piston 5 is no longer subjected to the thrust of the water. At this time, the second elastic member 7 rebounds and generates a thrust on the second piston 5 toward the third liquid port 61. The second elastic member 7 pushes the second piston 5 to slide from the fourth position to the third position and leave the discharge pipe 3, so that the discharge pipe 3 is conductive.
[0074] With this arrangement, when water inlet stops, no external force is required to push the second piston 5 away from the discharge pipe 3, and the operation is smoother.
[0075] According to an embodiment of the present application, on the other hand, a bathing device is also provided. Figures 3 to 10 As shown, it includes a device body 8 and any of the above water outlet components. The bathing device can be a shower head, and the device body 8 is a shower head body.
[0076] The device body 8 is provided with a liquid outlet cavity 81 and a plurality of liquid outlet heads 82. The liquid outlet cavity 81 is connected to each liquid outlet head 82 through a one-way valve, so that the one-way valve is unidirectional in the direction of flow from the liquid outlet cavity 81 to the liquid outlet head 82, so that water in the liquid outlet cavity 81 can flow to the liquid outlet head 82 through the one-way valve, and gas cannot flow from the liquid outlet head 82 through the one-way valve to the liquid outlet cavity 81 and then flow to the second liquid port 22. The second liquid port 22 of the water outlet assembly is connected to the liquid outlet cavity 81, and water is discharged from the second liquid port 22 of the water outlet assembly into the liquid outlet cavity 81 and then sprayed out from each liquid outlet head 82.
[0077] The technical effect brought by the bathing device is consistent with that of the water outlet component, so it will not be repeated.
[0078] The device body 8 is also provided with a water inlet structure, and the third liquid port 61 of the water outlet assembly is connected to the water inlet structure, so that water can flow into the third liquid port 61 through the water inlet structure.
[0079] As an optional embodiment, Fig. 9 , Fig.10 and Fig.13 As shown, the one-way valve is set as a duckbill valve 83, and a plurality of duckbill valves 83 are provided. Each duckbill valve 83 is connected to the liquid outlet cavity 81, so that the second liquid port 22 of the water outlet assembly is connected to the duckbill valve 83 through the liquid outlet cavity 81. The water entering the liquid outlet cavity 81 from the second liquid port 22 can be discharged through each duckbill valve 83 respectively, and each liquid outlet head 82 is correspondingly connected to a duckbill valve 83, so that the liquid outlet heads 82 are connected to the liquid outlet cavity 81 one by one through the duckbill valve 83, so that the water discharged from each duckbill valve 83 can be discharged from a corresponding liquid outlet head 82, so that after the water enters the liquid outlet cavity 81, it is discharged from each duckbill valve 83 respectively, and then discharged from each liquid outlet head 82 for the user to shower.
[0080] The duckbill valve 83 is commonly known as a rubber sewage check valve, also known as a back pressure flexible check valve, a duckbill valve check valve, a rubber check valve, a rubber check valve, a rubber slow closing check valve, etc. It is a special valve device. When there is no internal pressure, the outlet of the duckbill valve 83 closes under its own elasticity; as the internal pressure gradually increases, the outlet of the duckbill valve 83 gradually increases, thereby maintaining the liquid being discharged at a high flow rate.
[0081] In this way, when the first piston 1 is located at the second position, water can continuously enter the liquid outlet chamber 81 from the second liquid port 22. At this time, as the pressure in the liquid outlet chamber 81 gradually increases, water can be discharged from each duckbill valve 83 respectively, and then discharged through a corresponding liquid outlet head 82.
[0082] After the water intake is stopped, the first piston 1 is pushed to slide from the second position to the first position. During the sliding process of the first piston 1, before the second liquid port 22 is still connected with the first liquid port 21, part of the water in the liquid outlet chamber is sucked into the first cylinder body 2 and flows to the drain pipe 3 through the first liquid port 21 for discharge. When the first piston 1 is initially located between the second liquid port 22 and the first liquid port 21, until the first piston 1 slides to the first position, at least part of the water in the liquid outlet chamber is sucked to the side of the first piston 1 in the first cylinder body 2 away from the first liquid port 21. Due to the presence of the duckbill valve as a one-way valve, a negative pressure is formed in the liquid outlet chamber 81, the duckbill valve is pressed and closed, and the water cannot flow out through the one-way valve, ensuring that the water remaining in the liquid outlet chamber 81 will not drip from the liquid outlet head 82, avoiding the water from continuously dripping to generate noise or dripping on the user's body, causing trouble to the user.
[0083] As an optional embodiment, Fig.10 As shown, the bathing device further includes a drain head 84, the device body 8 is provided with a drain cavity 85, the drain head 84 is connected with the drain cavity 85, and one end of the drain pipe 3 of the water outlet assembly extending out of the second cylinder body 6 is connected with the drain cavity 85 through the connecting pipe 9. In this way, the water discharged from the drain pipe 3 can enter the drain cavity 85 through the pipeline, and then be discharged through the drain port.
[0084] Two or more drainage heads 84 may be provided to improve drainage efficiency.
[0085] As an optional embodiment, Figure 6 and Figure 7 As shown, at least two water outlet assemblies are provided, and the number may be two. The device body 8 is provided with a liquid inlet cavity 86, and the water inlet structure is communicated with the liquid inlet cavity 86, so that water can be introduced into the liquid inlet cavity 86 through the water inlet structure.
[0086] The third liquid ports 61 of each water outlet assembly are respectively connected to the liquid inlet chamber 86 , so that the water entering the liquid inlet chamber 86 can enter the second cylinder body 6 of each water outlet assembly from the corresponding third liquid ports 61 .
[0087] The second liquid ports 22 of each water outlet assembly are respectively communicated with the liquid outlet cavity 81 , so that the water discharged from the second liquid ports 22 of each water outlet assembly can enter the liquid outlet cavity 81 .
[0088] With this arrangement, when water is intaken, water enters the liquid outlet chamber 81 through each water outlet component respectively, and the water intake efficiency is higher; when the water intake is stopped, the first piston 1 of each water outlet component slides from the second position to the first position, so that the negative pressure formed in the liquid outlet chamber 81 is larger, further preventing water from dripping from the water outlet head.
[0089] As an optional embodiment, Figures 3 to 6As shown, the bathing device further includes a handle 10. A water channel is provided in the handle 10, and a switch is provided on the device body 8. The water channel is connected to the liquid inlet cavity 86 of the device body 8 through the switch, and thus connected to the third liquid port 61 of the water outlet assembly. In this way, the water channel is connected to the water source. After the switch is turned on, water can sequentially enter the second cylinder body 6 of the water outlet assembly through the water channel, the liquid inlet cavity 86 and the third liquid port 61. After the switch is turned off, water can no longer enter the liquid inlet cavity 86, and thus can no longer enter the second cylinder body 6 of the water outlet assembly.
[0090] Although the embodiments of the present application are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations are all within the scope defined by the present application.
