[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] The following is combined Figures 1 to 6 The present invention describes the water outlet device 100 provided in the embodiments of the present invention.

[0041] Specifically, the water outlet device 100 includes a first water inlet chamber 1, a second water inlet chamber 2, a first piston 3, a first elastic element 4, a second piston 5, and a second elastic element 6.

[0042] The first water inlet chamber 1 is provided with a water inlet 101 and a first water outlet 102. Optionally, the water inlet 101 is connected to a tap water pipe, and the first water outlet 102 is used to connect to the water outlet cavity 901 of the water outlet plate 9.

[0043] The second water inlet chamber 2 is connected to the first water inlet chamber 1, and the second water inlet chamber 2 is provided with a second water outlet 201. Optionally, the second water inlet chamber 2 is connected to and communicates with the first water inlet chamber 1, and the second water outlet 201 is used to communicate with the water outlet cavity 901 of the water outlet plate 9. For example, the second water outlet 201 and the first water outlet 102 are respectively connected to the corresponding water outlet cavity 901.

[0044] The first piston 3 is movably disposed in the first water inlet chamber 1. The first piston 3 has a gap with the inner wall of the first water inlet chamber 1. For example, the gap between the first piston 3 and the first water inlet chamber 1 can be an annular gap, a semi-annular gap or other types of gap.

[0045] Furthermore, when water is entering through the inlet 101, the first piston 3 moves away from the inlet 101 and closes the first outlet 102. That is, when water is entering through the inlet 101, the pressure of the water flow drives the first piston 3 to move away from the inlet 101, and the first piston 3 closes the first outlet 102, so that the water in the first inlet chamber 1 will not flow out from the first outlet 102.

[0046] The first elastic element 4 is used to drive the first piston 3 to move towards the water inlet 101. For example, the first elastic element 4 is located between the first water inlet chamber 1 and the first piston 3, and the first elastic element 4 can be set as a spring. When the water inlet 101 stops supplying water, the first elastic element 4 drives the first piston 3 to reset, so that the first piston 3 opens the first water outlet 102.

[0047] The second piston 5 is movably disposed in the second water inlet chamber 2 and passes through the second water outlet 201 in parallel; in other words, the second water outlet 201 is located on the movement trajectory of the second piston 5.

[0048] Furthermore, with water entering through inlet 101, the second piston 5 moves away from the axis of the second outlet 201. That is, with water entering through inlet 101, water passes through the first inlet chamber 1 into the second inlet chamber 2, pushing the second piston 5 to move away from the inlet 101 through the second outlet 201, so that the second outlet 201 can communicate with the first inlet chamber 1, thereby allowing water in the second inlet chamber 2 to flow out through the second outlet 201.

[0049] The second elastic element 6 is used to drive the second piston 5 to move towards the side of the second outlet hole 201 closer to the inlet 101. For example, the second elastic element 6 is located between the second inlet chamber 2 and the second piston 5, and the second elastic element 6 can be set as a spring. When the inlet 101 stops supplying water, the second elastic element 6 drives the second piston 5 to move towards the side of the second outlet hole 201 closer to the inlet 101 to reset.

[0050] Furthermore, during the resetting process of the second piston 5, a negative pressure is generated in the space on the side of the second piston 5 away from the water inlet 101. Since the second water outlet 201 is located on the side of the second piston 5 away from the water inlet 101 at this time, the second water inlet chamber 2 can draw water or air from the water outlet plate 9 through the second water outlet 201, so that the water outlet cavity 901 of the water outlet plate 9 forms a negative pressure.

[0051] In this embodiment, during use, the inlet 101 is connected to the tap water pipe, the second outlet 201 is connected to the corresponding outlet cavity 901 of the outlet plate 9, and the first outlet 102 can be connected to the drain cavity 904 of the outlet plate 9 or directly connected to the outside of the shower head.

[0052] refer to Figure 3 As shown in the figure, the curve represents the direction of water flow. When water is entering through inlet 101, water enters the first inlet chamber 1, and the pressure of the water flow drives the first piston 3 to move away from inlet 101. The first piston 3 closes the first outlet hole 102, preventing water in the first inlet chamber 1 from flowing out of the first outlet hole 102. At the same time, water can flow into the second inlet chamber 2 through the gap between the first piston 3 and the inner wall of the first inlet chamber 1.

[0053] Furthermore, the water entering the second inlet chamber 2 pushes the second piston 5 to move towards the side of the second outlet hole 201 away from the inlet 101, so that the second outlet hole 201 can communicate with the first inlet chamber 1, thereby allowing the water in the second inlet chamber 2 to flow out through the second outlet hole 201. The water flowing out of the second outlet hole 201 flows out through the outlet cavity 901 of the outlet plate 9, so that the shower head can spray water.

[0054] refer to Figure 4 As shown in the figure, the curve in the figure represents the direction of water. When the water inlet 101 stops flowing, the first elastic element 4 drives the first piston 3 to move towards the water inlet 101 and then reset, so that the first piston 3 opens the first water outlet 102, so that the water on the side of the first piston 3 away from the water inlet 101 can be quickly discharged through the first water outlet 102.

[0055] Furthermore, the second elastic element 6 drives the second piston 5 to move and reset towards the side of the second water outlet 201 near the water inlet 101. Water on the side of the second piston 5 near the water inlet 101 enters the first water inlet chamber 1 under the pushing action of the second piston 5 and is discharged through the first water outlet 102, so that the second piston 5 can move smoothly.

[0056] At the same time, during the resetting process of the second piston 5, a negative pressure is generated in the space on the side of the second piston 5 away from the water inlet 101. Since the second water outlet 201 is located on the side of the second piston 5 away from the water inlet 101 at this time, the second water inlet chamber 2 can draw water or air from the water outlet plate 9 through the second water outlet 201, so that the water outlet cavity 901 of the water outlet plate 9 forms a negative pressure, and is discharged from the first water outlet 102 to prevent water from dripping from the water outlet cavity 901.

[0057] With this configuration, when water is introduced, the hydraulic force drives the first piston 3 and the second piston 5 to move, the first water outlet 102 closes, and water flows out of the second water outlet 201. When water introduction stops, the first elastic element 4 and the second elastic element 6 respectively drive the first piston 3 and the second piston 5 to reset, so that the first water outlet 102 drains water outward, and the second water inlet chamber 2 forms a negative pressure under the action of the second piston 5, which draws water and air from the water outlet plate 9 to prevent the water outlet plate 9 from dripping.

[0058] refer to Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the water outlet device 100 further includes a sealing ring 7. One end of the sealing ring 7 is connected to the end of the first piston 3 away from the water inlet 101, and the other end of the sealing ring 7 forms an flared opening in the direction away from the first piston 3 and abuts against the inner wall of the first water inlet chamber 1.

[0059] For example, the sealing ring 7 is configured as a conical ring, with the constricted end of the sealing ring 7 connected to the end of the first piston 3 away from the water inlet 101, and the flared end of the sealing ring 7 extending away from the first piston 3 and abutting against the inner wall of the first water inlet chamber 1.

[0060] In this embodiment, when water is entering through the inlet 101, the water entering the first inlet chamber 1 from the inlet 101 acts on the outer wall of the sealing ring 7, driving the sealing ring 7 to deform inward, thereby causing the sealing ring 7 to separate from the inner wall of the first inlet chamber 1, so that the water can pass through the sealing ring 7 and enter the second inlet chamber 2.

[0061] Understandably, by setting the sealing ring 7, the contact area between the sealing ring 7 and the water flow is larger without affecting the water flow into the second water inlet chamber 2. Therefore, when water is entering through the water inlet 101, the sealing ring 7 is subjected to a greater thrust from the water flow, which enables the sealing ring 7 to assist the first piston 3 in better resisting the elastic force of the first elastic element 4, so that the first piston 3 can reliably seal the first water outlet 102.

[0062] Additionally, refer to Figure 4As shown, since the sealing ring 7 has a sealing effect with the inner wall of the first water inlet chamber 1, when the first elastic member 4 drives the first piston 3 to move towards the water inlet 101, the side of the first piston 3 away from the water inlet 101 can form a certain negative pressure effect, so that the water outlet chamber 901 connected to the first water outlet 102 forms a negative pressure effect, reducing the dripping problem.

[0063] refer to Figure 3 and Figure 4 As shown, in some embodiments provided by this utility model, the first water inlet chamber 1 is provided with a drain pipe 8.

[0064] Specifically, one end of the drain pipe 8 is located outside the first water inlet chamber 1, and the other end of the drain pipe 8 is located inside the first water inlet chamber 1. The end of the drain pipe 8 located inside the first water inlet chamber 1 is located on the side of the first piston 3 away from the water inlet 101 and extends toward the first piston 3. The cavity of the drain pipe 8 forms a first water outlet 102. Correspondingly, when water is entering through the water inlet 101, the first piston 3 abuts against the opening of the drain pipe 8.

[0065] In this embodiment, when water is introduced, the first piston 3 closes the drain pipe 8 opening, preventing water from flowing out of the first outlet hole 102, so that water can only flow to the second inlet chamber 2 through the gap between the first piston 3 and the inner wall of the first inlet chamber 1, thereby ensuring that the water flows along the designed path and achieves the specific function.

[0066] The first piston 3 abuts against the opening of the drain pipe 8. Compared to other simple sealing methods, this structure, which directly abuts against the opening, can achieve a better seal. When water is entering through the inlet 101, it can more effectively prevent water in the first inlet chamber 1 from flowing out through the first outlet hole 102, thus improving the reliability and stability of the device.

[0067] One end of the drain pipe 8 is located outside the first water inlet chamber 1, and the other end is located inside the first water inlet chamber 1 and extends toward the first piston 3. This layout makes reasonable use of the space of the first water inlet chamber 1, making the connection and cooperation between the components more compact, which is conducive to the miniaturization and integration design of the entire water outlet device 100.

[0068] Furthermore, a shoulder is provided on the outer wall of the end of the drain pipe 8 facing the first piston 3, and the first elastic member 4 is fitted on the outside of the drain pipe 8, with one end of the first elastic member 4 abutting against the shoulder and the other end abutting against the first piston 3.

[0069] In this embodiment, the first elastic element 4 moves axially along the drain pipe 8 to avoid skewing or jamming, ensuring the linear movement of the first piston 3 and improving sealing reliability. Furthermore, directly using the drain pipe 8 as the spring guide shaft reduces the number of parts.

[0070] In addition, this arrangement makes full use of the outer wall space of the drain pipe 8, and the first elastic element 4 is fitted on it. No additional space is needed to install the elastic element, making the structure of the entire water outlet device 100 more compact and the space utilization rate higher, which is conducive to realizing the miniaturization design of the device.

[0071] refer to Figures 2-4 As shown, in some embodiments provided by this utility model, the second piston 5 includes a piston body 501 and a sealing member 502 fitted on the outside of the piston body 501.

[0072] There is a gap between the piston body 501 and the inner wall of the second water inlet chamber 2, and the seal 502 abuts against the inner wall of the second water inlet chamber 2. The seal 502 can be a sealing ring.

[0073] Furthermore, the second water outlet 201 is provided on the side wall of the second water inlet chamber 2. When water is entering through the water inlet 101, the piston body 501 abuts against the end of the second water inlet chamber 2 away from the first water inlet chamber 1, and the seal 502 is located on the side of the second water outlet 201 away from the first water inlet chamber 1.

[0074] In this embodiment, when water enters through the inlet 101, the piston body 501 can abut against the end of the second inlet chamber 2 away from the first inlet chamber 1 under water pressure. At this time, the seal 502 is located on the side of the second outlet 201 away from the first inlet chamber 1, so that the second outlet 201 is connected to the first inlet chamber 1, and the normal water outlet function is realized.

[0075] When water intake stops at inlet 101, piston 501 resets under the action of second elastic element 6, causing second inlet chamber 2 to draw water or air from outlet plate 9 through second outlet hole 201, preventing outlet plate 9 from dripping. This design allows for flexible control of the water flow channel opening and closing according to the water intake status, meeting functional requirements under different working conditions.

[0076] The seal 502 abuts against the inner wall of the second water inlet chamber 2, which can effectively prevent water from leaking from the gap between the seal 502 and the inner wall of the second water inlet chamber 2, ensuring that the water flows along the designed path.

[0077] Optionally, the end of the second water inlet chamber 2 away from the first water inlet chamber 1 is provided with an end cap, and the second elastic member 6 is disposed between the end cap and the second piston 5.

[0078] Furthermore, a guide post is provided on the inner side of the end cap, and the second elastic element 6 is fitted on the guide post. The guide post can radially limit the second elastic element 6, preventing the second elastic element 6 from shifting or tilting. This helps to ensure that the elastic force of the second elastic element 6 can be accurately transmitted to the second piston 5 along the predetermined direction, making the movement of the second piston 5 more stable and accurate, and avoiding abnormal movement of the second piston 5 due to the shift of the elastic element, which would affect the normal operation of the water outlet device 100.

[0079] Accordingly, the piston body 501 has a clearance hole at one end near the end cap, which is used for the guide post and the second elastic element 6 to extend into. The clearance hole provides space for the guide post and the second elastic element 6 to extend into, so that the piston body 501 can achieve a precise fit with the end cap, the guide post and the second elastic element 6.

[0080] This design ensures accurate relative positions between components. For example, it ensures that the second piston 5 will not interfere with the guide post or the second elastic element 6 during movement, thereby ensuring the stability and reliability of the entire water outlet device 100.

[0081] In some embodiments provided by this utility model, both the first water inlet chamber 1 and the second water inlet chamber 2 are configured as pipe structures, and the first water inlet chamber 1 and the second water inlet chamber 2 are connected by insertion, that is, they are coaxially arranged. Optionally, a sealing ring is provided between the first water inlet chamber 1 and the second water inlet chamber 2, thereby improving the sealing effect between the first water inlet chamber 1 and the second water inlet chamber 2.

[0082] In this embodiment, the pipe structure has a regular shape, is easy to design and manufacture, and the plug-in connection method is simple, effectively utilizing space and making the overall structure more compact. Furthermore, the plug-in connection requires no additional complex tools or installation processes, allowing operators to quickly connect the first water inlet chamber 1 and the second water inlet chamber 2, reducing installation costs and time.

[0083] In addition, by connecting the first water inlet chamber 1 and the second water inlet chamber 2 by inserting them together, it is convenient to install the first piston 3 and the second piston 3 into the first water inlet chamber 1 and the second water inlet chamber 2 respectively.

[0084] In addition, if one of the water inlet chambers malfunctions or requires maintenance, the plug-in connection makes disassembly relatively convenient. The two water inlet chambers can be easily separated to repair or replace a single water inlet chamber without affecting other components, thus improving maintenance efficiency and reducing maintenance costs.

[0085] This utility model embodiment also provides a shower head.

[0086] Specifically, the shower head includes a water outlet plate 9 and a water outlet device 100 as described above.

[0087] The water outlet plate 9 includes a water outlet cavity 901 and a water outlet hole 902. The second water outlet hole 201 is connected to the water outlet cavity 901, and the water outlet cavity 901 is provided with the water outlet hole 902. For example, the water outlet cavity 901 is provided with multiple water outlet holes 902.

[0088] That is, the water flowing out of the second water outlet 201 enters the corresponding water outlet chamber 901 and is sprayed out from the water outlet 902 of the water outlet chamber 901.

[0089] It should be noted that the shower head includes the water outlet device 100, and therefore also includes all the advantages of the water outlet device 100 mentioned above, so it will not be elaborated further.

[0090] Optionally, the second water inlet chamber 2 is provided with a connector at the position corresponding to the second water outlet 201. The connector is inserted into the water outlet plate 9 and communicates with the corresponding water outlet cavity 901 of the water outlet plate 9.

[0091] Optionally, the second water inlet chamber 2 is connected to the water outlet plate 9 to improve the connection strength between the two and prevent them from separating. For example, the second water inlet chamber 2 can be connected to the water outlet plate 9 by bonding, screwing, welding or riveting.

[0092] In some embodiments provided by this utility model, the water outlet plate 9 further includes a drainage cavity 904 and a drainage hole 905. The first water outlet 102 is connected to the drainage cavity 904, and the drainage cavity 904 is provided with the drainage hole 905.

[0093] That is, the water flowing out of the first water outlet 102 enters the corresponding drain chamber 904 and flows out through the drain hole 905 of the drain chamber 904. In this way, the space on the water outlet plate 9 can be fully utilized to form the drain chamber 904 to discharge the water discharged from the first water outlet 102, thereby improving the space utilization rate of the water outlet plate 9 and thus improving the overall structural compactness of the shower head.

[0094] Optionally, the first water inlet chamber 1 is provided with a connector at the position corresponding to the first water outlet 102. The connector is inserted into the water outlet plate 9 and communicates with the corresponding water outlet cavity 901 of the water outlet plate 9.

[0095] Optionally, the first water inlet chamber 1 is connected to the water outlet plate 9 to improve the connection strength between the first water inlet chamber 1 and the water outlet plate 9 and prevent them from separating. For example, the first water inlet chamber 1 can be connected to the water outlet plate 9 by bonding, screwing, welding or riveting.

[0096] In some embodiments provided by this utility model, the shower head also includes a connector 10, a third piston 11, and a third elastic member 12.

[0097] The connector 10 has an inlet end 1001, an outlet end 1002 and a connecting end 1003, and the inlet end 1001, the outlet end 1002 and the connecting end 1003 are connected to each other.

[0098] Specifically, the inlet end 1001 is used to connect to the tap water pipeline, the outlet end 1002 is connected to the inlet 101 of the first inlet chamber 1, and the connection end 1003 is connected to the drain chamber 904. For example, the connection end 1003 is plugged into the outlet plate 9 and connected to the drain chamber 904 in the outlet plate 9.

[0099] The third piston 11 is movably mounted on the connecting end 1003. When water is entering the water inlet end 1001, the third piston 11 moves away from the water inlet end 1001.

[0100] The third elastic element 12 is used to drive the third piston 11 to move towards the water inlet 1001.

[0101] In this embodiment, when water enters the inlet 1001, the pressure inside the connector 10 increases, and the water pressure drives the third piston 11 to move away from the inlet 1001, opening the inlet 101. The water inside the connector 10 enters the interior of the first inlet chamber 1 through the inlet 101.

[0102] Furthermore, when water intake at the inlet 1001 is stopped, the third piston 11 moves towards the inlet 1001; or, when water intake at the inlet 1001 is stopped, the third piston 11 moves away from the drain chamber 904. It is understood that when water intake at the inlet 1001 is stopped, the water pressure decreases, and the third elastic element 12 recovers its deformation, thereby enabling the third piston 11 to perform the aforementioned action.

[0103] As the third piston 11 moves away from the drain chamber 904, a negative pressure is generated in the cavity on the side of the third piston 11 away from the water inlet 1001. This allows the connecting end 1003 to draw water from the drain chamber 904 connected to the first water outlet 102, creating a negative pressure in the drain chamber 904 as well. This prevents water from dripping from the drain hole 905 of the drain chamber 904, thereby further improving the anti-drip effect of the shower head.

[0104] Optionally, the inlet end 1001 and the connecting end 1003 are coaxially arranged, and the outlet end 1002 is arranged on the side wall of the inlet end 1001 or the connecting end 1003.

[0105] Furthermore, when water is entering through the inlet end 1001, the third piston 11 moves away from the inlet end 1001 and opens the outlet end 1002. When water stops entering through the inlet end 1001, the third elastic element 12 drives the third piston 11 to move closer to the inlet end 1001, and the third piston 11 closes the outlet end 1002.

[0106] Optionally, a guide post is provided at the position corresponding to the water outlet plate 9 and the connecting end 1003, and the guide post extends into the interior of the connecting end 1003. The third elastic element 12 is fitted on the guide post, and the guide post can radially limit the third elastic element 12 to prevent the third elastic element 12 from shifting or tilting. This helps to ensure that the elastic force of the third elastic element 12 can be accurately transmitted to the third piston 11 along the predetermined direction, making the movement of the third piston 11 more stable and accurate, and avoiding abnormal movement of the third piston 11 due to the shift of the elastic element.

[0107] Correspondingly, the third piston 11 has a clearance hole at one end near the water outlet plate 9, which is used for the guide post and the third elastic element 12 to extend into. The clearance hole provides space for the guide post and the third elastic element 12 to extend into, so that the piston body 501 can achieve a precise fit with the water outlet plate 9, the guide post and the third elastic element 12.

[0108] This design ensures accurate relative positional relationships between the various components. For example, it ensures that the third piston 11 will not interfere with the guide post or the third elastic element 12 during movement, thereby ensuring the stability and reliability of the entire water outlet device 100.

[0109] In some embodiments of this utility model, there are multiple water outlet devices 100. Thus, multiple water outlet devices 100 mean more water outlet channels, enabling more water to be sprayed simultaneously, thereby increasing the overall water output. Furthermore, water outlet devices 100 at different locations can spray water over a wider area, allowing the body to come into more comprehensive contact with water during showering, improving the comfort and experience of showering.

[0110] In addition, when some water outlet devices 100 malfunction or become clogged, the other water outlet devices 100 can still work normally without affecting the use of the entire shower head, thus improving the flexibility and reliability of the shower head.

[0111] Optionally, the connector 10 is provided with multiple water outlets 1002, each of which is connected to the water inlet 101 of the corresponding water outlet device 100.

[0112] refer to Figure 5As shown, in some embodiments of this utility model, the water outlet cavity 901 corresponding to the second water outlet 201 includes a plurality of water outlet channels 903. The plurality of water outlet channels 903 are radially distributed, and the plurality of water outlet channels 903 are interconnected with each other and connected to the second water outlet 201. Each water outlet channel 903 is provided with a corresponding water outlet 902.

[0113] In this embodiment, multiple radially distributed water outlet channels 903 can achieve the same water outlet function without increasing the overall size of the water outlet cavity 901. This avoids the situation where a single channel occupies a large space, thereby reducing unnecessary space in the water outlet cavity 901 and reducing residual water in the water outlet cavity 901, making the second piston 5 more efficient at absorbing water.

[0114] In some embodiments of this utility model, the shower head further includes a water distribution component 13. The water distribution component 13 is provided with multiple water distribution channels 1301, which are interconnected and connected to the second water outlet 201. Each water distribution channel 1301 is connected to a corresponding water outlet chamber 901. Optionally, the multiple water distribution channels 1301 are arranged radially.

[0115] In this embodiment, the multiple water distribution channels 1301 of the water distribution component 13 can evenly distribute the incoming water flow to each water outlet 901. Through the precise distribution of the water distribution component 13, each water outlet 901 can obtain a stable water supply, avoiding the problem of excessive water flow in some areas and insufficient water flow in other areas. This ensures that each water outlet 902 can obtain a relatively balanced water flow, improving the consistency and comfort of the shower experience.

[0116] Furthermore, the interconnected structure of multiple water distribution channels 1301 reduces the risk of blockage in a single channel. If a minor blockage occurs in one channel, the water can still flow to the corresponding outlet chamber 901 through other connected channels, without affecting the normal operation of the entire shower head.

[0117] Optionally, at least a portion of the water outlet chamber 901 connected to the water distribution element 13 includes a plurality of water outlet channels 903.

[0118] In some embodiments provided by this utility model, the shower head also includes a ball head assembly 14, which is connected to the water inlet 101. Optionally, the ball head assembly 14 is threadedly connected to the water inlet end 1001 of the connector 10.

[0119] The ball head assembly 14 typically allows for flexible rotation within a certain range, enabling the shower head to be easily adjusted after installation according to the user's needs and actual usage scenarios to achieve optimal spray effect and coverage. For example, users can adjust the shower head to a suitable angle to better accommodate users of different heights, or make fine adjustments based on different shower locations, improving the shower head's flexibility and comfort.

[0120] In addition, the threaded connection makes the installation and removal of the ball head assembly 14 and the connector 10 convenient. During the production and assembly of the shower head, workers can quickly screw the ball head assembly 14 onto the inlet end 1001 of the connector 10, improving production efficiency. In later use, if the ball head assembly 14 or the connector 10 is damaged and needs replacement, it can be easily unscrewed for repair or replacement, reducing maintenance costs and difficulty.

[0121] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
