Description

Technical Field

[0001] This utility model relates to the field of drinking water equipment technology, and in particular to a faucet sealing structure, and a water dispenser faucet with a faucet sealing structure. Background Technology

[0002] As a common drinking water supply device in daily life, the sealing reliability of the faucet structure of water dispensers directly affects the user experience and equipment safety. Traditional water dispenser faucets usually use a single sealing ring that contacts the water outlet, achieving a closed seal through the axial compression deformation of the sealing ring.

[0003] However, in practical applications, this type of structure has poor water pressure adaptability. Especially in typical household or commercial scenarios, the water supply system pressure is often around 2 kg. At this pressure, the sealing ring relies on only one-sided compression for fixation, and under long-term water pressure, it is prone to local micro-deformation or misalignment, resulting in the sealing surface not being able to completely fit the water outlet, thus causing leakage. When the water supply pressure exceeds 2 kg due to factors such as pipeline adjustment, instantaneous impact during equipment startup, or water pressure fluctuations in high-rise buildings, such as reaching 3-5 kg ​​or even higher, the balance between radial pressure and axial compression force on the sealing ring is disrupted. This can easily lead to the sealing ring shifting, loosening, or even falling off directly from the installation position. This not only exacerbates the leakage but may also damage other internal components of the faucet due to water flow impact, affecting the normal function of the water dispenser. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a faucet sealing structure in which the sealing rubber ring is installed in an embedded fit on both sides, which can achieve a more stable seal at the water outlet, solve the problems of water leakage under 2 kg water pressure and sealing ring falling off under 2 kg water pressure. Actual tests show that it can withstand water pressure up to 9 kg, ensuring stable sealing under all working conditions and improving the applicability and durability of the faucet.

Combined with the auxiliary push of the elastic element to strengthen the installation, it realizes multi-directional limiting and stable sealing of the sealing rubber ring, effectively preventing the sealing rubber ring from shifting or falling off during water pressure impact or long-term use. It effectively blocks water leakage under low pressure conditions of 2 kg. In actual tests, the sealing rubber ring can withstand impacts of up to 9 kg, preventing deformation, displacement or falling off of the sealing rubber ring during use.

[0026] As a common drinking water supply device in daily life, the sealing reliability of the faucet structure of water dispensers directly affects the user experience and equipment safety. Traditional water dispenser faucets usually use a single sealing ring that contacts the water outlet, achieving a closed seal through the axial compression deformation of the sealing ring.

[0027] However, in practical applications, this type of structure has poor water pressure adaptability. Especially in typical household or commercial scenarios, the water supply system pressure is often around 2 kg. At this pressure, the sealing ring relies on only one-sided compression for fixation, and under long-term water pressure, it is prone to local micro-deformation or misalignment, resulting in the sealing surface not being able to completely fit the water outlet, thus causing leakage. When the water supply pressure exceeds 2 kg due to factors such as pipeline adjustment, instantaneous impact during equipment startup, or water pressure fluctuations in high-rise buildings, such as reaching 3-5 kg ​​or even higher, the balance between radial pressure and axial compression force on the sealing ring is disrupted. This can easily lead to the sealing ring shifting, loosening, or even falling off directly from the installation position. This not only exacerbates the leakage but may also damage other internal components of the faucet due to water flow impact, affecting the normal function of the water dispenser.

[0028] Therefore, such as Figure 1 As shown, the faucet sealing structure proposed in this utility model includes a water-sealing rubber ring 100, a driving block 200 disposed at the bottom of the water-sealing rubber ring 100 and embedded therein, and a pushing block 300 disposed at the top of the water-sealing rubber ring 100 and embedded therein. (Refer to...) Figure 2 A water-sealing adhesive is installed at the water outlet 7021. An elastic element 400 is connected to the side of the push block 300 opposite to the water-sealing adhesive ring 100, pushing the water-sealing adhesive ring 100 towards the side of the drive block 200. In application, the drive block 200 can drive the water-sealing adhesive ring 100 to move upwards and downwards to open and close the water outlet 7021. It should be noted that the upper end of the sealing ring 100 is embedded in the push block 300, and the lower end is embedded in the drive block 200, forming a two-way mechanical fixing structure. Combined with the auxiliary push of the elastic element 400 to strengthen the installation, it achieves multi-directional limiting and stable sealing of the sealing ring 100, effectively preventing the sealing ring 100 from shifting or falling off during water pressure impact or long-term use. It effectively blocks water leakage under low pressure conditions of 2 kg. In actual tests, the sealing ring 100 can withstand impacts of up to 9 kg, preventing deformation, displacement or falling off of the sealing ring 100 during use. Thus, it meets the requirements of low-pressure leak prevention and high-pressure anti-fall-off, significantly improving sealing stability and faucet reliability.

[0029] Refer to Figure 1In some embodiments of this utility model, an embedding groove 101 matching the shape of the driving block 200 is provided at the bottom of the sealing rubber ring 100, so that the driving block 200 can be accurately embedded into the bottom of the sealing rubber ring 100, forming a stable directional fit structure. Specifically, the matching design of the embedding groove 101 and the driving block 200 ensures that the driving block 200 and the sealing rubber ring 100 are tightly fitted in the axial and radial directions, preventing the driving block 200 from shaking or shifting within the sealing rubber ring 100, thereby improving the transmission stability of the driving block 200 to the sealing rubber ring 100; at the same time, this embedded fit can efficiently transmit the lifting and lowering motion of the driving block 200 to the sealing rubber ring 100, ensuring that the sealing rubber ring 100 maintains an accurate opening and closing position when moving synchronously with the driving block 200, thereby precisely controlling the opening and closing state of the water outlet 7021 and enhancing the operational reliability of the faucet sealing structure.

[0030] In some embodiments, the depth of the mounting groove is less than the thickness of the driving block, and the driving block is partially embedded in the mounting groove (not shown in the figure). In some embodiments, the depth of the mounting groove is equal to the thickness of the driving block, and the driving block is precisely embedded in the mounting groove (not shown in the figure). In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the depth of the mounting groove 101 is greater than the thickness of the driving block 200, so that after the driving block 200 is embedded in the sealing ring 100, a certain gap space is maintained in the mounting groove 101. It should be noted that this gap not only provides elastic buffer margin for the fit between the driving block 200 and the sealing ring 100, but also absorbs stress through the gap when the component is slightly deformed due to water pressure impact or temperature change, avoiding damage to the driving block 200 and the sealing ring 100 due to excessive compression. At the same time, the redundant design in the depth direction further reduces the risk of the driving block 200 coming out of the mounting groove 101. Even under high water pressure or frequent operation conditions, the driving block 200 can still be stably placed in the mounting groove 101 and maintain a reliable connection with the sealing ring 100, thereby improving the long-term durability and deformation resistance of the structure. Optionally, the mounting groove 101 is circular in the thickness direction section of the sealing ring 100. Utilizing the symmetry of the circular cross-section, the force distribution on the driving block 200 within the mounting groove 101 is more uniform. Understandably, the circular structure eliminates the localized stress concentration problems that may be caused by sharp corners or irregular cross-sections, ensuring a stable fit between the driving block 200 and the sealing ring 100 at any rotation angle, avoiding transmission jamming or sealing failure due to assembly angle deviations. Simultaneously, the circular mounting groove 101 has a simple manufacturing process and good consistency, enabling standardized manufacturing to guarantee the matching accuracy between each mounting groove 101 and the driving block 200, further improving the assembly efficiency and overall reliability of the faucet sealing structure.

[0031] Refer to Figure 1In some embodiments of this utility model, the top of the sealing rubber ring 100 is provided with an annular protrusion 102, and the bottom of the push block 300 is provided with a positioning groove 301. The annular protrusion 102 abuts against the groove wall of the positioning groove 301, increasing the contact friction and limiting constraint between the two, preventing the sealing rubber ring 100 from radially sliding or axially shifting below the push block 300. At the same time, the cooperation between the annular protrusion 102 and the positioning groove 301 can accurately position the installation position of the sealing rubber ring 100, ensuring that the sealing surface of the sealing rubber ring 100 and the outlet 7021 always maintain the correct angle and contact pressure, thereby improving the pushing stability of the push block 300 on the sealing rubber ring 100 and further strengthening the sealing effect. Optionally, the circumferential surface of the positioning groove 301 is conical, so that the positioning groove 301 at the bottom of the push block 300 and the annular protrusion 102 at the top of the sealing rubber ring 100 form an adaptive guiding cooperation. It is easy to understand that the conical circumference can guide the annular protrusion 102 to slide smoothly into the positioning groove 301, reducing assembly difficulty and reducing wear on the sealing ring 100 during installation; at the same time, the conical structure will have a tightening tendency towards the center when under force, further increasing the contact pressure between the annular protrusion 102 and the groove wall of the positioning groove 301, enhancing the limiting effect between the two, and preventing the sealing ring 100 from coming out of the positioning groove 301 during high water pressure or frequent operation, thereby improving the stability and sealing reliability of the connection between the push block 300 and the sealing ring 100.

[0032] Furthermore, refer to Figure 1 In some embodiments of this utility model, the upper surface of the push block 300 is provided with an aligning conical surface 302, and the elastic element 400 is a compression spring, with one end of the compression spring abutting against the aligning conical surface 302. Similarly, the tilt angle of the aligning conical surface 302 can guide the axial force of the compression spring to act more concentratedly on the central area of ​​the push block 300, avoiding uneven force distribution on the sealing ring 100 caused by spring force dispersion; at the same time, the compression spring provides a continuous and stable pushing force through elastic deformation, which, together with the guiding effect of the aligning conical surface 302, ensures that the push block 300 always pushes the sealing ring 100 with uniform pressure, keeping the sealing ring 100 in close contact with the outlet 7021, thereby improving the pushing efficiency and sealing stability of the elastic element 400 on the sealing ring 100, and further optimizing the low-pressure leak-proof performance. In some manufacturing applications, the push block 300 is a spacer sheet, which forms a concave-convex structure through central pressing, that is, conical surfaces are formed on both the upper and lower surfaces.

[0033] Refer to Figure 2 and Figure 3The water dispenser faucet according to an embodiment of the present invention includes a faucet sealing structure, a pull rod 500, and a handle 510. Specifically, a push block 300, a water-sealing rubber ring 100, and a driving block 200 are arranged sequentially along the axial direction of the pull rod 500. The push block 300 and the water-sealing rubber ring 100 are sleeved on the pull rod 500, and the driving block 200 is fixedly connected to the pull rod 500. The handle 510 is connected to the end of the pull rod 500 away from the driving block 200, and the handle 510 is used to drive the pull rod 500 and the driving block 200 to move up and down. This achieves precise control of the water outlet 7021 through mechanical linkage. Users only need to operate the handle 510 to complete the on / off action, which is simple to operate and has a rapid response. At the same time, the axial arrangement and sleeved connection of each component makes the structure more compact, reduces space occupation, and improves the integration and practicality of the water dispenser faucet.

[0034] Refer to Figure 2 and Figure 3In some embodiments of this utility model, the pull rod 500 is provided with a sealing ring 520 and a recessed insert 530, further improving the sealing performance and structural stability of the faucet. The sealing ring 520 is located at the end of the elastic element 400 opposite to the water-sealing ring 100, effectively sealing the top of the pull rod 500 and preventing water leakage along the outer wall of the pull rod 500 to the outside of the faucet. The recessed insert 530 is located between the sealing ring 520 and the elastic element 400, and is embedded in the sealing ring 520. This provides positioning support for the sealing ring 520, preventing it from shifting or deforming under water pressure. The embedded fit also enhances the tightness of the connection between the recessed insert 530 and the sealing ring 520, avoiding sealing failure caused by high-pressure water flow impact. This ensures the sealing reliability of the pull rod 500 area and extends the service life of the faucet. In some embodiments, the concave insert 530 and the push block 300 have the same structure and are symmetrically arranged at both ends of the elastic member 400. The opposite end can play a self-guiding and positioning role for both ends of the elastic member 400, and the opposite end is firmly embedded with the sealing ring 520 and the water sealing ring 100 respectively. Furthermore, the water dispenser faucet includes a main body 700 and a locking cover 600. The locking cover 600 is threaded onto the top of the main body 700. The pull rod 500 is vertically slidably mounted on the locking cover 600. The handle 510 is located on the outside of the locking cover 600 and is used to drive the pull rod 500 to move vertically. A horizontally arranged water inlet chamber 701 is provided in the middle of the main body 700, and a vertically arranged water outlet chamber 702 is provided at the bottom of the main body 700. The elastic element 400, the push block 300, the water sealing ring 100, and the driving block 200 are all provided inside the main body 700. The water sealing ring 100 is used to open and close the top of the water outlet chamber 702. Overall, a complete pressure-bearing and control system is formed, which enables stable water output when the water flows from the inlet chamber 701 to the outlet chamber 702 through the precise opening and closing control of the sealing rubber ring 100. At the same time, the threaded connection between the main body 700 and the locking cover 600 enhances the overall structural stability and can withstand water pressure impacts of up to 9 kg, ensuring the safe and reliable operation of the water dispenser faucet under high pressure.
