DETAILED DESCRIPTION
[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.
[0045] The embodiments of the present application are described below in combination with Figures 1 to 13 .
[0046] According to the embodiments of the present application, in one aspect, a water outlet assembly is provided, as shown in Figure 1 , which comprises a first cylinder 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 2 is provided with a first liquid port 21 and a second liquid port 22. The first piston 1 is slidably arranged in the first cylinder 2 to form a piston cylinder, and the first piston 1 can slide along the first cylinder 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 located outside the two ends of the first piston 1 respectively, 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 outside the same end of the first piston 1, and at this time the first liquid port 21 is connected with 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 liquid discharge pipe 3, so that the liquid cannot flow from the first liquid port 21 to the liquid discharge pipe 3 for discharge. When the blocking member slides to the second state, the blocking member leaves the liquid discharge pipe 3, so that the liquid discharge pipe 3 is connected, at this time the liquid discharge pipe 3 is connected with the first liquid port 21, and the liquid can flow from the first liquid port 21 to the liquid discharge pipe 3 for discharge.
[0049] In this way, when the water outlet assembly is used, as shown in Figure 1 the normal state, the blocking member is 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. The liquid outlet cavity 81 is connected to the liquid outlet head 82 of the bathing device through the one-way valve, so that the one-way valve is unidirectionally open in the direction of water flowing from the liquid outlet cavity 81 to the liquid outlet head 82, and thus water in the liquid outlet cavity 81 can flow to the liquid outlet head 82 through the one-way valve, while air cannot flow from the liquid outlet head 82 to the liquid outlet cavity 81 through the one-way valve and then to the second liquid port 22.
[0050] As shown in Figure 2 , in the process of sliding the blocking member to the first state, water is discharged into the first cylinder 2 through the first liquid port 21, and the water can push the first piston 1 to slide along the first cylinder 2 to the second position. When 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 2 can flow out to the liquid outlet cavity 81 through the second liquid port 22, and then be distributed to each liquid outlet head 82 for discharge, thereby realizing the normal water spraying function of the bathing device.
[0051] When the use is stopped, as shown in Figure 1 , the first liquid port 21 stops water inflow, the blocking member slides from the first state to the second state, and the drain pipe 3 is open, so that 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] In the process of sliding 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 2 and flows to the drain pipe 3 through the first liquid port 21 for discharge. In the process of the first piston 1 starting to be located between the second liquid port 22 and the first liquid port 21 and sliding to the first position, at least part of the water in the liquid outlet cavity is sucked into the first cylinder 2 on the side of the first piston 1 away from the first liquid port 21. Due to the presence of the one-way valve, a negative pressure is formed in the liquid outlet cavity 81, and the one-way valve is tightly closed, so that water cannot flow out through the one-way valve, and thus the water remaining in the liquid outlet cavity 81 cannot drip from the liquid outlet head 82, achieving the effect of stopping immediately after stopping, and avoiding noise caused by continuous dripping or dripping on the user's body, which causes disturbance to the user.
[0053] As shown in Figure 11 , the first piston 1 can include a moving block 11 and a rubber ring 12, and the rubber ring 12 is installed in the installation groove on the moving block 11. When the first piston 1 is installed in the first cylinder 2, the rubber ring 12 is attached to the inner wall of the first cylinder 2.
[0054] As an optional embodiment, as shown in Figure 1 and Figure 2As shown, the water outlet assembly also includes a first elastic element 4. The first end of the first elastic element 4 is connected to the first piston 1, and the second end of the second elastic element 7 is connected to the first cylinder 2. Normally, the first piston 1 is located in the first position. During use, when the water flow and pressure drive the first piston 1 to slide towards the second position, the first elastic element 4 undergoes elastic deformation. Under the action of the first elastic element 4, the first piston 1 tends to slide towards the first position. After the driving force on the first piston 1 is removed, the first elastic element 4 rebounds, and the first piston 1 can slide from the second position back to the first position.
[0055] The first elastic element 4 can be a spring. A mounting post 23 is provided inside the first cylinder 2. The first end of the first elastic element 4 is connected to the end of the first piston 1 near the second liquid port 22, and the second end is sleeved on the mounting post 23. Thus, when the first piston 1 is driven to slide to the second position, the first elastic element 4 is compressed. After the driving force on the first piston 1 is released, the first elastic element 4 rebounds, pushing the first piston 1 to slide from the second position back to the first position.
[0056] Specifically, after water enters the first cylinder 2 through the first liquid port 21, it pushes the first piston 1 to slide from the first position to the second position. When the first piston 1 slides to the second position, it slides to the side of the second liquid port 22 away from the first liquid port 21, and the first elastic element 4 is compressed. The water in the first cylinder 2 can be discharged through the second liquid port 22 to the liquid outlet chamber 81, and then distributed to each liquid outlet head 82 for discharge, realizing the conventional water spraying function.
[0057] After the first liquid inlet 21 stops receiving water, the first piston 1 is no longer pushed by the water. The sealing member is slid to the second state, and the drain pipe 3 is opened. The first elastic member 4 rebounds, pushing the first piston 1 from the second position to the first position. During this process, the water on the side of the first piston 1 closest to the first liquid inlet 21 is pushed by the first piston 1 and flows from the first liquid inlet 21 to the drain pipe 3 for discharge.
[0058] This design allows the first piston 1 to automatically slide from the second position to the first position after a water outage, eliminating the need for manual operation and making it more convenient to use.
[0059] As an optional embodiment, such as Figure 1 and Figure 2 As shown, the water outlet assembly also includes a second cylinder 6, which has 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 6 and is connected to the fourth liquid port 62, and then to the first liquid port 21.
[0060] The blocking member comprises a second piston 5, which is slidably arranged in a second cylinder 6 to form a piston cylinder, and the second piston 5 is always located between a third liquid port 61 and a fourth liquid port 62. That is, the second piston 5 can slide along the second cylinder 6 in the region between the third liquid port 61 and the fourth liquid port 62, thereby sliding between a third position and a fourth position. When the second piston 5 slides to the fourth position, the second piston 5 abuts against one end of the drain pipe 3 extending into the second cylinder 6 and blocks the drain 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 the one end of the drain pipe 3 extending into the second cylinder 6, so that the drain port is open, and the blocking member is in the second state.
[0061] For the second piston 5, a first end thereof is close to the third liquid port 61, and a second end thereof 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 of the second piston 5, water can flow from the first end of the second piston 5 to the second end of the second piston 5 through the second piston 5.
[0062] The second piston 5 can be a one-way piston cup, which is a special sealing element and is widely used in gas or liquid transmission systems. As shown in Figure 12 The second piston 5 comprises a piston body 51 and a flange 52 obliquely arranged on the piston body, and the oblique direction of the flange 52 is the sliding direction of the second piston 5 from the third position to the fourth position. The flange 52 can be deformed and is normally attached to the inner wall of the second cylinder 6, and when the water pressure on the first end of the second piston 5 is greater than the water pressure on the second end of the second piston 5, the flange 52 is deformed and leaves 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.
[0063] When the second piston 5 slides to the fourth position, the second piston 5 abuts against one end of the drain pipe 3 extending into the second cylinder 6 and blocks the drain pipe 3, and as water continues to enter, the second piston 5 cannot continue to slide, resulting in that the water pressure on the first end of the second piston 5 is greater than the water pressure on the second end, the flange 52 is deformed and leaves the inner wall of the second cylinder 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 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 in communication with 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.
[0065] When water enters the second cylinder 6 through the third liquid port 61, it pushes the second piston 5 to slide to the fourth position. When the second piston 5 slides to the fourth position, it abuts against the liquid discharge pipe 3 and blocks the end of the liquid discharge pipe 3 that extends into the second cylinder 6, i.e., 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 that the water pressure on the first end of the second piston 5 is greater than that on the second end, so that the flange 52 deforms and leaves 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 liquid discharge 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] When water enters the first cylinder 2 through the first liquid port 21, it pushes the first piston 1 to slide along the first cylinder 2 to the second position. When 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 2 can be discharged to the liquid outlet chamber 81 through the second liquid port 22, and then divided to the liquid outlet heads 82 of the bathing device to be discharged, realizing the normal water spraying function.
[0067] When the use is stopped, the third liquid port 61 stops water inflow. The second piston 5 is slid to the third position to make the liquid discharge pipe 3 conductive, 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 with the first liquid port 21, part of the water in the liquid outlet chamber 81 is sucked into the first cylinder 2 and flows to the liquid discharge pipe 3 through the first liquid port 21. During the process that the first piston 1 starts to be located between the second liquid port 22 and the first liquid port 21 and slides to the first position, at least part of the water in the liquid outlet chamber 81 is sucked into the first cylinder 2 on the side of the first piston 1 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 to be discharged.
[0069] When the first piston 1 slides from the second position to the first position, due to the existence of the one-way valve, a negative pressure is formed in the liquid outlet chamber 81, the one-way valve is pressed to close, so that 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 noise caused by continuous dripping or the water dripping on the user's body, which causes disturbance to the user.
[0070] As an optional embodiment, as shown in FIG. 6, the first piston 1 is provided with a plurality of liquid outlet ports 71, and the liquid outlet chamber 81 is provided with a plurality of liquid outlet heads 82 corresponding to the liquid outlet ports 71. Figure 1 and Figure 2As shown, the water outlet assembly further comprises a second elastic member 7. The first end of the second elastic member 7 is connected with the second piston 5, and the second end of the second elastic member 7 is connected with the second cylinder body 6. In normal state, 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 is elastically deformed. 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 removed, the second elastic member 7 rebounds and can push the second piston 5 to slide from the fourth position to the third position.
[0071] The second elastic member 7 can be a spring. The first end of the second elastic member 7 is connected with 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 drainage pipe 3 and connected with the inner wall of the second cylinder body 6. In this way, when the second piston 5 is driven to slide to the fourth position, the second elastic member 7 is compressed, and when the second piston 5 slides to the fourth position, the second piston 5 abuts against the drainage pipe 3 and blocks the drainage pipe 3, and the blocking member is in the first state. After the driving force on the second piston 5 is removed, the second elastic member 7 rebounds and pushes the second piston 5 to slide from the fourth position to the third position. At this time, the second piston 5 leaves the drainage pipe 3, the drainage pipe 3 is conducted, 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, the second piston 5 is pushed to slide to the fourth position, and the second elastic member 7 is compressed. When the second piston 5 slides to the fourth position, the second piston 5 blocks the drainage pipe 3. As water continues to enter, the second piston 5 cannot continue to slide, resulting in that the water pressure at the first end of the second piston 5 is greater than that at the second end. The flange 52 deforms 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 flowing to the fourth liquid port 62.
[0073] After the third liquid port 61 stops water inflow, the second piston 5 is no longer subjected to the water thrust. At this time, the second elastic member 7 rebounds and generates a thrust to the second piston 5 towards 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 drainage pipe 3, so that the drainage pipe 3 is conducted.
[0074] In this way, when water inflow is stopped, the second piston 5 does not need to be pushed away from the drainage pipe 3 by external force, and the operation is more smooth.
[0075] According to the embodiments of the present application, on the other hand, a bathing device is also provided. As shown in the drawings, Figures 3 to 10 The device body 8 and any of the above water outlet assemblies are included. 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 are arranged. The liquid outlet cavity 81 is connected with each liquid outlet head 82 through a one-way valve. The one-way valve is unidirectional in the direction from the liquid outlet cavity 81 to the liquid outlet head 82, so that the water in the liquid outlet cavity 81 can flow to the liquid outlet head 82 through the one-way valve, and the gas cannot flow to the liquid outlet cavity 81 through the one-way valve from the liquid outlet head 82 to the second liquid port 22. The second liquid port 22 of the water outlet assembly is communicated with the liquid outlet cavity 81. After the water is discharged from the second liquid port 22 of the water outlet assembly into the liquid outlet cavity 81, the water is sprayed from each liquid outlet head 82.
[0077] The technical effects brought by the bathing device are consistent with those of the water outlet assembly, and thus will not be described again.
[0078] The device body 8 is further provided with a water inlet structure. The third liquid port 61 of the water outlet assembly is communicated with the water inlet structure, so that water can be supplied to the third liquid port 61 through the water inlet structure.
[0079] As an optional embodiment, as shown in Figure 9 , Figure 10 and Figure 13 , the one-way valve is a duckbill valve 83, and a plurality of duckbill valves 83 are arranged. Each duckbill valve 83 is communicated with the liquid outlet cavity 81, so that the second liquid port 22 of the water outlet assembly is communicated with 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. Each liquid outlet head 82 is communicated with one duckbill valve 83, so that each liquid outlet head 82 is communicated with the liquid outlet cavity 81 through the duckbill valve 83. The water discharged from each duckbill valve 83 can be discharged from one liquid outlet head 82, so that the water entering the liquid outlet cavity 81 is discharged from each duckbill valve 83 and then from each liquid outlet head 82 for the user to take a 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, and a rubber slow-closing check valve. It is a special valve device. Under the condition of no internal pressure, the outlet of the duckbill valve 83 is closed under the elastic action of itself. With the gradual increase of the internal pressure, the outlet of the duckbill valve 83 gradually increases, so that the liquid can be 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 cavity 81 from the second liquid port 22. At this time, with the gradual increase of the pressure in the liquid outlet cavity 81, the water can be discharged from each duckbill valve 83 and then through one liquid outlet head 82.
[0082] After the water supply is stopped, the first piston 1 is pushed to slide from the second position to the first position. During the sliding of the first piston 1, before the second liquid port 22 is still communicated with the first liquid port 21, part of the water in the liquid outlet cavity is sucked into the first cylinder 2 and flows to the liquid discharge pipe 3 through the first liquid port 21 for discharge. During the process that the first piston 1 starts to be 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 into the first cylinder 2 on the side of the first piston 1 away from the first liquid port 21. Due to the existence of the duckbill valve as a one-way valve, negative pressure is formed in the liquid outlet cavity 81, the duckbill valve is pressed to close tightly, water cannot flow out through the one-way valve, and it is ensured that the water remaining in the liquid outlet cavity 81 cannot drip from the liquid outlet head 82, so as to avoid that the water continuously drips to produce noise or drips on the body of the user to cause disturbance to the user.
[0083] As an optional embodiment, as shown in Figure 10 , the bathing device further comprises a liquid discharge head 84, the device body 8 is provided with a liquid discharge cavity 85, the liquid discharge head 84 is communicated with the liquid discharge cavity 85, and the liquid discharge pipe 3 of the water outlet assembly is communicated with the liquid discharge cavity 85 through the connecting pipe 9 at one end extending out of the second cylinder 6. In this way, the water discharged from the liquid discharge pipe 3 can enter the liquid discharge cavity 85 through the pipeline and then be discharged through the liquid discharge port.
[0084] Among them, the liquid discharge head 84 can be provided with two or more, so as to improve the drainage efficiency.
[0085] As an optional embodiment, as shown in Figure 6 and Figure 7 , the water outlet assembly is provided with at least two, which can 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 supplied to the liquid inlet cavity 86 through the water inlet structure.
[0086] The third liquid port 61 of each water outlet assembly is respectively communicated with the liquid inlet cavity 86, so that the water entering the liquid inlet cavity 86 can enter the second cylinder 6 of each water outlet assembly from the corresponding third liquid port 61.
[0087] The second liquid port 22 of each water outlet assembly is respectively communicated with the liquid outlet cavity 81, so that the water discharged from the second liquid port 22 of each water outlet assembly can enter the liquid outlet cavity 81.
[0088] In this way, when the water is supplied, the water enters the liquid outlet cavity 81 through each water outlet assembly, and the water supply efficiency is higher; when the water supply is stopped, the first piston 1 of each water outlet assembly slides from the second position to the first position, so that the negative pressure formed in the liquid outlet cavity 81 is larger, and water dripping from the water outlet head is further avoided.
[0089] As an optional embodiment, as shown in Figures 3 to 6As shown, the bathing device further comprises a handle 10. A water channel is formed in the handle 10, and a switch is arranged on the device body 8. The water channel is communicated with the liquid inlet cavity 86 of the device body 8 through the switch, and is communicated with the third liquid port 61 of the water outlet assembly. In this way, the water channel is connected to a water source. When the switch is opened, water can 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 in sequence. When the switch is closed, water cannot continue to enter the liquid inlet cavity 86, and thus cannot 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 drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the present application.
