Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, specifically to a water outlet device. Background Technology

[0002] In existing showerhead designs, the suction mechanism and the instant-off mechanism are usually two separate designs, each serving a different function. Achieving both functions simultaneously often requires a complex structural design and more components, leading to increased costs and reduced reliability. Currently, most showerhead products on the market only have a single instant-off or suction function, rarely combining both. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned defects or problems in the background technology and provide a water outlet device that, while keeping the number of parts simplified, successfully integrates multiple functions such as water flow, air intake and spraying, and instant shut-off.

[0004] To achieve the above objectives, the various embodiments of this utility model adopt the following technical solutions, but are not limited to the following solutions:

[0005] The first technical solution relates to a water outlet device, including a water outlet section having a water outlet channel extending along the water outlet direction and an elastically deformable section for forming at least part of the water outlet channel; and a venting section having an air inlet channel communicating with the atmosphere. The venting section passes through the elastically deformable section and extends into the water outlet channel, so that the air inlet channel communicates with the water outlet channel. When water enters the water outlet device, the elastically deformable section deforms under water pressure, causing water to flow into the water outlet channel through the gap between the elastically deformable section and the venting section, and driving air from the air inlet channel into the water outlet channel, so that air and water mix to form bubble water. When the water outlet device stops entering water, the elastically deformable section returns to its original shape and abuts against the venting section, preventing water in the water outlet device from leaking out of the water outlet channel.

[0006] The second technical solution is based on the first technical solution, wherein the elastic deformation part protrudes radially relative to the inlet of the water outlet channel and abuts against the side wall of the venting part, and forms an interference fit with the venting part so that the water in the water outlet device will not leak under the action of no water pressure.

[0007] The third technical solution is based on the second technical solution, wherein the inner circumference of the elastic deformation part protrudes radially into the water outlet channel to form an annular flange, and the annular flange abuts against the venting part under no water pressure to form a circumferential interference fit seal.

[0008] The fourth technical solution is based on the third technical solution, wherein the inlet of the water outlet channel is provided with an axially protruding annular wall, the elastic deformation part is sleeved on the annular wall, and the elastic deformation part at the annular flange protrudes axially toward the water outlet channel relative to the annular wall to form an arc-shaped structure that accommodates the annular wall.

[0009] The fifth technical solution is based on the fourth technical solution, in which the highest part of the arc-shaped structure remains in a non-contact state with other parts of the water outlet device.

[0010] The sixth technical solution is based on the first technical solution, wherein the inner wall of the outlet of the water outlet channel is provided with a narrowing section, and the cross-sectional area of ​​the narrowing section gradually decreases along the water outlet direction.

[0011] The seventh technical solution is based on the sixth technical solution, wherein the part of the venting section that passes through the elastic deformation section and extends to the water outlet channel is an inverted cone structure, and the outlet of the air inlet channel faces the narrowing section.

[0012] The eighth technical solution is based on any one of the first to seventh technical solutions, including a water inlet component and a water outlet component, which includes a top cover, a water outlet cover and a face cover. The top cover is provided with at least one vent, and the air inlet of the air inlet channel is located on the surface of the top cover. The water outlet cover is provided with at least one water outlet, which is an elastically deformable part. The outlet of the elastically deformable part forms a narrow section. The face cover is provided with at least one installation channel, and the water outlet is at least partially embedded in the installation channel to form a water outlet channel. The water outlet channel and the water outlet form a water outlet, and the vent, the water outlet, and the water outlet channel correspond one-to-one.

[0013] The ninth technical solution is based on the eighth technical solution, wherein the upper cover is provided with a receiving groove facing the water outlet cover and corresponding to the water outlet to accommodate the protruding water outlet.

[0014] The tenth technical solution is based on the eighth technical solution. The water inlet component includes a ball head, a water-saving plate, a receiving component, a friction ring, and a cap. The ball head has a water inlet channel inside. The water-saving plate and the receiving component are installed in the water inlet channel of the ball head in sequence. The ball head is fitted into the cap through the friction ring. The cap is threadedly connected to the upper cover.

[0015] As can be seen from the above description of the various embodiments of the present utility model, compared with the prior art, the various embodiments of the present utility model have the following beneficial effects:

[0016] In the first technical solution and related embodiments, the water outlet device, through the cooperation of the water outlet section and the venting section, successfully integrates multiple functions such as water supply, air intake shower, and instant shut-off while maintaining a streamlined number of parts. When water is supplied, the water pressure causes the elastic deformation section to undergo elastic deformation. The elastic deformation section is then pushed towards the water outlet by the water pressure, gradually separating from the venting section to form a gap. This gap creates a negative pressure ratio at the point where the water outlet area suddenly increases, attracting external gas through the air intake channel of the venting section, forming an independent gas-liquid mixing channel. This results in the water sprayed from the water outlet being rich in gas, providing a unique shower experience. After the water is turned off, the elastic deformation section naturally contracts due to the loss of water pressure, re-cooperating with the venting section to immediately stop the water flow. Simultaneously, the air intake channel remains connected to the external atmosphere, ensuring that the internal air can be smoothly discharged when the elastic deformation section rebounds, achieving internal and external force balance and avoiding the problem of difficulty in the water outlet's rebound.

[0017] In the second technical solution and related embodiments, the elastic deformation part of the water outlet device is designed to protrude relative to the inlet of the water outlet channel and form an interference fit with the venting part, forming an effective sealing barrier. Under the action of no water pressure, that is, when the device is in a non-working state or a water stop state, this sealing barrier can prevent the water in the water outlet device from leaking to the outside.

[0018] In the third technical solution and related embodiments, the annular flange enhances the circumferential interference fit sealing between the elastic deformation part and the venting part.

[0019] In the fourth flow technology solution and related embodiments, the annular wall plays a role in limiting the degree of elastic deformation of the elastic deformation part, effectively preventing the elastic deformation part from undergoing excessive deformation due to excessive water pressure, and ensuring the stability and durability of the water outlet device.

[0020] In the fifth technical solution and related embodiments, the elastic deformation part protrudes and forms an arc-shaped structure facing the annular wall, and the highest part of the arc-shaped structure does not contact the shell, thus optimizing the elastic deformation part's response to water pressure. Specifically, when water flows through, the water pressure will act on the arc-shaped structure of the elastic deformation part, making it easier and more uniform for the elastic deformation part to undergo elastic deformation along the water outlet direction.

[0021] In the sixth technical solution and related embodiments, the narrowing section can effectively slow down the speed of water flow through the water outlet channel, providing sufficient time for externally introduced gas to fully mix with the water flow inside the water outlet. This not only enhances the uniformity of gas-liquid mixing but also further improves the water spray effect, bringing users a more delicate and gas-rich shower experience.

[0022] In the seventh technical solution and related embodiments, the inverted conical structure design causes the cross-section of the venting section to gradually decrease within the water outlet channel. When water flows through the device, the water pressure acts on the elastic deformation section, causing it to undergo elastic deformation and move towards the water outlet direction. As the elastic deformation section gradually separates from the inverted conical outer wall of the venting section, the cross-section of the water outlet channel suddenly increases at a certain position. This change leads to the generation of a negative pressure effect in that area. The negative pressure effect is the result of a sudden decrease in water flow velocity and an increase in static pressure. It forms a low-pressure area that effectively attracts external gas through the air inlet channel into the water outlet channel.

[0023] In the eighth technical solution and related embodiments, the water outlet device can quickly form a gas-liquid mixing channel when receiving water pressure, spraying out gas-rich water droplets to bring a unique shower experience. When the water pressure disappears, the water outlet immediately resets, re-forming an interference fit with the vent, achieving instant shut-off.

[0024] In the ninth technical solution and related embodiments, the receiving tank allows water to converge there to apply pressure to the protruding part of the water outlet.

[0025] In the tenth technical solution and related embodiments, the ball head is provided with a water inlet channel, and the water-saving plate and the receiving part are installed in the water inlet channel in sequence to effectively regulate and control the flow rate and pressure of the water flow, ensure the stability and uniformity of the water flow, and prevent the negative impact that excessive water pressure may cause to the water outlet, such as excessive deformation or damage.

[0040] In the claims, description and accompanying drawings of this utility model, the terms "comprising," "having," and variations thereof are used to mean "including but not limited to."

[0041] See Figures 1 to 7 ,like Figure 1 As shown, a water outlet device includes an inlet component and an outlet component.

[0042] Water inlet components, such as Figure 1 , Figure 4 and Figure 6 As shown, it includes a ball head 4, a water-saving plate 5, a receiving component 6, a friction ring 8, and a cap 7. The ball head 4 has an inlet channel 41 inside, and the water-saving plate 5 and the receiving component 6 are sequentially installed within the inlet channel 41 of the ball head 4. The ball head 4 is fitted into the cap 7 via the friction ring 8. The ball head 4 serves as the starting point of the water inlet path, responsible for adjusting the water flow direction and controlling the water outlet direction.

[0043] The water-saving plate 5 uses a flow-limiting structure to perform preliminary treatment of the water flow, reducing the water pressure.

[0044] The receiving component 6 is installed inside the ball head 4, positioned behind the water-saving plate 5. Its main function is to fix the axial position of the water-saving plate 5 to prevent it from shifting when subjected to water flow impact or vibration. Furthermore, the receiving component 6 has a guide channel 62 designed to match the water inlet channel 41, effectively guiding the water flow regulated by the water-saving plate 5 smoothly to the downstream components, reducing turbulence and pressure loss. Both ends of the receiving component 6 are sealed to the inside of the ball head 4 by O-rings 61, ensuring smooth water flow from the guide channel 62 of the receiving component 6.

[0045] The friction ring 8 increases friction to ensure the stability of the ball head 4 within the cap 7, preventing unnecessary rotation due to water flow impact. The ball head 4 has an internal water inlet channel 41, within which the water-saving plate 5 and the receiving component 6 are sequentially installed. This effectively regulates and controls the water flow rate and pressure, ensuring the stability and uniformity of the water flow, and also preventing negative impacts on the outlet 20 that could result from excessive water pressure, such as excessive deformation or damage. The water inlet assembly is existing technology and will not be described further.

[0046] Water outlet components, such as Figure 1 As shown, it includes an upper cover 1, a water outlet cover 2, and a face cover 3, which are sequentially fixed together and connected to the water inlet assembly. Specifically, the upper cover 1, the water outlet cover 2, and the face cover 3 are fixed together by screws 16. The upper cover 1 is threadedly connected to the cap 7 of the water inlet assembly.

[0047] The cover 3 has at least one installation channel extending in the water outlet direction, and the inlet of the installation channel has an axially protruding annular wall 31.

[0048] Water outlet cover 2, such as Figure 2 As shown, it is provided with at least one water outlet 20, and the water outlet 20 has a water outlet passage. The water outlet 20 is made of an elastic material. In this embodiment, the water outlet 20 is made of soft rubber material.

[0049] The spout 20 passes through the mounting channel of the faceplate 3 and is at least partially embedded in the mounting channel to form an elastically deformable part. This means that the spout 20 can be partially embedded in the mounting channel of the faceplate 3 or completely embedded in the mounting channel of the faceplate 3. Therefore, the mounting channel and the water outlet passage of the spout 20 together constitute a complete water outlet channel 30, and the water outlet channel 30 and the spout 20 form a water outlet part 21. In this embodiment, the spout 20 is completely embedded in the mounting channel, and the water outlet passage of the spout 20 forms the water outlet channel 30 extending in the water outlet direction.

[0050] like Figure 4 As shown, the inner wall of the outlet of the water outlet channel 30 is provided with a narrowing section 24. The narrowing section 24 is formed by the inward bulging of the inner wall of the outlet of the water nozzle 20, and its cross-sectional area gradually decreases along the water outlet direction. The setting of the narrowing section 24 not only plays a certain role in constraining and guiding the water flow, but also affects the mixing effect of water flow and air during the water outlet process, which helps to form water bubbles of a specific shape.

[0051] The elastic deformation part protrudes axially toward the water outlet channel 30 relative to the annular wall 31, forming an arc-shaped structure 25 that accommodates the annular wall 31. This arc-shaped structure allows the elastic deformation part to undergo elastic deformation more smoothly when subjected to force, and to quickly recover its deformation after the external force disappears, ensuring the normal operation of the water outlet device.

[0052] Top cover 1, as shown Figure 3 As shown, it is provided with at least one vent 10. The vent 10 is installed at the corresponding position of the water outlet channel 30 and adopts an inverted conical structure design, with the conical head facing the water outlet direction of the water outlet channel 30. Specifically, the vent 10 exhibits an inverted conical needle-like characteristic, with its tip always pointing towards the water outlet direction of the water outlet channel 30. The vent 10 is provided with an air inlet channel 11 that communicates with the atmosphere. The air inlet hole 12 of the air inlet channel 11 is located on the surface of the upper cover 1, and the air outlet hole 13 of the air inlet channel 11 points towards the water outlet direction of the water outlet channel 30. The vent 10 passes through the elastic deformation part and extends into the water outlet channel 30, so that the air inlet channel 11 communicates with the water outlet channel 30, providing a channel for air to enter for subsequent air-water mixing. Specifically, since the water outlet 20 is completely embedded in the water outlet channel 30, the vent 10 passes through the water outlet 20 and extends into the interior of the water outlet 20.

[0053] The number of vents 10, water outlets 20, and water outlet channels 30 are the same, and their positions correspond one-to-one. The upper cover 1 has a receiving groove 15 facing the water outlet cover 2 and corresponding to the water outlet 20 to accommodate the protruding water outlet 20. The vents 10 are located in the middle of the receiving groove 15. The receiving groove 15 allows water to converge there to apply pressure to the protruding part of the water outlet 20.

[0054] Among them, such as Figure 4 As shown, the upper cover 1 has a water passage 14 leading to the water outlets 20. The upper cover 1 and the water outlet cover 2 have water distribution channels 27 surrounding the water outlets 20. The water passage 14 connects to the water inlet channel 41 and leads to the water distribution channels 27, forming a water inlet path. This water outlet device guides the water flow to the water distribution channels 27 by designing the water passage 14 leading to the water outlets 20 on the upper cover 1 and setting the water distribution channels 27 surrounding the water outlets 20 on the upper cover 1 and the water outlet cover 2, thereby evenly distributing the water to each water outlet 20. This design optimizes the water flow path, reduces water flow resistance, and ensures that each water outlet 20 receives a stable and sufficient water supply.

[0055] The cap 7 is connected to the water passage 14 in the upper cover 1 by threads on its outer wall, and the ball head 4 is tightly fixed to the outer wall of the water passage 14 by the sealing ring 43 and the washer 42.

[0056] like Figure 7 As shown, when water enters the water outlet device, the elastic deformation part deforms under the action of water pressure, causing water to flow through the gap between the elastic deformation part and the air vent 10 into the water outlet 20, and driving air from the air inlet channel 11 into the water outlet 20, so that the air and water mix to form bubble water.

[0057] like Figure 5 As shown, when the water outlet device stops receiving water, the elastic deformation part returns to its original shape and abuts against the vent 10, preventing water in the water outlet device from leaking out of the water outlet 20.

[0058] During the deformation movement of the elastic deformation part, the vent 10 remains inside the water outlet 20, playing an effective guiding role and preventing functional failure due to seal misalignment.

[0059] Specifically, the elastically deformable part protrudes radially relative to the inlet of the water outlet channel 30, abutting against the side wall of the venting part 10 and forming an interference fit with the side wall of the venting part 10, so that water in the water outlet device will not leak under no water pressure. The elastically deformable part of the water outlet device is designed to protrude radially relative to the inlet of the water outlet channel 30 and form an interference fit with the venting part 10, forming an effective sealing barrier. Under no water pressure, that is, when the device is in a non-operating state or a water outage state, this sealing barrier can prevent water in the water outlet device from leaking to the outside.

[0060] In this embodiment, the inner circumference of the elastic deformation part protrudes radially inward toward the water outlet channel 30, forming an annular flange 26. The annular flange 26 abuts against the conical outer wall of the venting part 10 under no water pressure, forming a circumferential interference fit seal. The annular flange 26 enhances the circumferential interference fit seal between the elastic deformation part and the venting part 10.

[0061] The elastic deformation portion at the annular flange 26 protrudes axially toward the water outlet channel 30 relative to the annular wall 31, forming an arc-shaped structure 25 that accommodates the annular wall 31. The highest part of the arc-shaped structure 25 remains in non-contact with other parts of the water outlet device; specifically, the highest part of the arc-shaped structure 25 does not abut against the receiving groove 15. This design optimizes the elastic deformation portion's response to water pressure. Specifically, when water flows through, the water pressure acts on the arc-shaped structure 25 of the elastic deformation portion, making it easier and more uniform for the elastic deformation portion to undergo elastic deformation along the water outlet direction. The annular wall 31 limits the degree of elastic deformation of the arc-shaped structure 25, effectively preventing excessive deformation of the arc-shaped structure 25 due to excessive water pressure, ensuring the stability and durability of the water outlet device.

[0062] In this embodiment, since the water outlet 20 completely covers the water outlet channel 30, the inner wall of the outlet of the water outlet 20 bulges to form a narrowing section 24. The narrowing section 24 can effectively slow down the speed of water flow through the water outlet channel 30, providing sufficient time for externally introduced gas to fully mix with the water flow inside the water outlet 20. This not only enhances the uniformity of gas-liquid mixing but also further improves the water spray effect, bringing users a more delicate and gas-rich shower experience.

[0063] In this embodiment, the inverted conical structure design causes the cross-section of the vent 10 within the water outlet channel 30 to gradually decrease. When water flows through the device, the water pressure acts on the elastic deformation part, causing it to undergo elastic deformation and move towards the water outlet direction. As the elastic deformation part gradually separates from the inverted conical outer wall of the vent 10, the cross-section of the water outlet channel 30 suddenly increases at a certain position. This change leads to the generation of a negative pressure effect in that area. The negative pressure effect is the result of a sudden decrease in water flow velocity and an increase in static pressure. It forms a low-pressure area that can effectively attract external gas through the air inlet channel 11 into the water outlet channel 30.

[0064] In this embodiment, the water outlet device, through the cooperation of the water outlet section 21 and the ventilation section 10, successfully integrates multiple functions such as water supply, air intake and shower spray, and instant shut-off while maintaining a streamlined number of parts. When water is supplied, the water pressure causes the elastic deformation section to undergo elastic deformation. The elastic deformation section is then pushed towards the water outlet direction by the water pressure, gradually separating from the ventilation section 10 to form a gap. This gap generates a negative pressure ratio at the point where the water outlet area suddenly increases, attracting external gas to enter through the air intake channel 11 of the ventilation section 10, forming an independent gas-liquid mixing channel. This makes the water sprayed by the water outlet section 21 rich in gas, bringing a unique shower experience. After the water is turned off, the elastic deformation section naturally contracts due to the loss of water pressure, re-cooperating with the ventilation section 10 to immediately block the water flow. At the same time, the air intake channel 11 always remains connected to the outside atmosphere, ensuring that the internal air can be smoothly discharged when the elastic deformation section rebounds, achieving a balance of internal and external forces and avoiding the problem of difficulty in the rebound of the water outlet 20.

[0065] In other embodiments, the outlet end of the water outlet channel 30 can be configured to be suitable for connecting an air suction device. An air suction structure can be provided at the outlet end of the water outlet channel 30 as needed to enhance the gas content in the water spray of the water outlet section 21, creating a richer and more diverse shower experience. For example, a standardized interface structure can be designed at the outlet end of the water outlet channel 30. This interface structure can be a threaded interface, a snap-fit ​​interface, or other connection methods that facilitate quick installation and disassembly. The size and specifications of the interface must match common air suction devices on the market to ensure that users can easily purchase and install a suitable air suction device.

[0066] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
