Description

Technical Field

[0001] This invention relates to the field of bathroom fixtures, and in particular to a new type of time-delay faucet. Background Technology

[0002] The invention of time-delay faucets was to prevent users from forgetting to turn off the tap or wasting water resources by using water for a long time. However, existing time-delay faucets have a relatively complex structure, or are difficult to disassemble and assemble. Time-delay faucets are generally used in public places such as hotels and shopping malls. If the product is damaged, it is not easy to be discovered, and the repair cost is high. In addition, existing time-delay faucets have many components and complex structures. In order to ensure the stability and durability of their time-delay components, they generally need to be assembled with a pure copper water-passing body. Therefore, the cost is high and the manufacturing process is relatively limited. Summary of the Invention

[0003] The primary objective of this invention is to develop a time-delay faucet that is simple in structure and easy to assemble and disassemble. The second objective of this invention is to provide a time-delay faucet that can use a plastic water channel, has a lower cost, and a simpler manufacturing process.

[0004] To achieve the purpose of this invention, a novel time-delay faucet is disclosed, comprising a main body shell, wherein the main body shell has a side water outlet shell; An internally conductive plastic core is built into the main body shell. The plastic core has a side wall water outlet. The water outlet is sealed with a water outlet pipe that extends along the inside of the side water outlet shell. The bottom of the plastic core is the water inlet channel. A time-delay assembly includes, from bottom to top, a time-delay cup, a bushing with a water passage gap, a sealing gasket, a valve core seat, and a time-delay handwheel movably sleeved above the valve core seat. The valve core seat is locked to the upper part of the main body shell and simultaneously sealed to the upper outer wall of the plastic core to achieve position fixation. A time-delay spring is provided between the time-delay handwheel and the valve core seat. The delay sleeve cup is hung inside the plastic core, and its side wall has a water inlet. A delay sealing gasket is fixedly fitted below a delay screw, which is close to the side wall of the delay sleeve cup and can be displaced with the side wall of the delay sleeve cup under axial force. A sealing ring is fixedly fitted above the delay screw, and the upper part of the delay screw can movably pass through the bushing, sealing gasket, valve core seat, and delay spring, and is further fixed to the delay handwheel. The delay screw can movably seal through the sealing gasket; the delay spring is fully extended or slightly compressed. The contraction causes the delay screw to move upwards, allowing the sealing ring to be placed against the bushing for a tight seal. The diameter of the portion of the delay screw corresponding to the bushing is smaller than that of the bushing. When the delay handwheel is tightened, the delay spring is compressed, and the sealing ring moves downwards away from the bushing. This allows water to flow from the bottom of the plastic core through the inlet on the side wall of the delay sleeve cup, and then through the gap between the bushing and the delay screw, further flowing into the outlet pipe through the water passage of the bushing to achieve water outlet. As the delay spring returns to its extended state, the sealing ring closes the outlet against the bushing.

[0005] Furthermore, the bottom of the bushing is an annular base, and the annular base is provided with several extended support bars at intervals. The interval between each pair of extended support bars is the water passage interval. The water passage interval forms an arc-shaped groove slope at the annular base so that after passing through the water passage interval of the bushing, the water flows along the arc-shaped groove slope into the outlet pipe, thereby ensuring a smooth water flow.

[0006] Furthermore, the upper wall of the plastic core is configured as a double-layer wall at the water outlet to form a water outlet partition. The inner wall of the double-layer wall is completely used to hang the delay sleeve cup, and the outer wall is provided with the water outlet. The outer wall is sealed and fitted by the valve core seat.

[0007] Furthermore, the valve core seat is a seat body with a central through-hole, wherein a transverse annular partition is provided inside, dividing it into an upper seat body and a lower seat body. The lower seat body has a double-layered annular wall extending downward longitudinally, namely an inner annular wall and an outer annular wall. The inner annular wall surrounds the mounting cavity, allowing the sealing gasket and the delay support strip of the bushing to be built into and fixed therein, and the inner annular wall abuts against the outer upper wall of the annular base of the bushing; the outer annular wall is locked to the upper part of the main body shell, and at the same time seals and fits with the upper outer wall of the plastic core to achieve position fixation; thereby ensuring that the lower wall of the annular base of the bushing is partially sealed and clamped with the delay cup.

[0008] Furthermore, the external water source is sealed and connected to the bottom of the plastic core via an external spiral tube.

[0009] Furthermore, the time-delay sealing gasket is a Y-shaped annular sealing gasket. The outwardly inclined annular portion of the Y-shape abuts against the side wall of the time-delay sleeve cup, allowing it to move upward or downward under axial force while sealing. This ensures the time-delay spring returns to its extended state. The time-delay sealing gasket is pushed by the time-delay spring and slowly moves upward against the side wall of the time-delay sleeve cup. When the sealing ring abuts against the bushing, the water outlet is closed, ultimately achieving the effect of delayed water outlet.

[0010] With the above structure, the main shell of this patent does not need to be made of copper. It can also be made of zinc alloy or gold-plated low-cost shell. As long as the material of its internal plastic core and water outlet pipe meets the national standard for water passage, such as water-passable plastic material, it is acceptable. In the actual assembly process, it is only necessary to disassemble the delay screw and delay handwheel (unscrew), and then remove the valve core seat. Then, the extension screw and other accessories can be directly removed, thus achieving disassembly. The assembly process is also simple and easy. This structural design can not only ensure the stability of the delay, but also achieve the technical effect of low cost and easy assembly. Attached Figure Description

[0013] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1-8As shown, a new type of time-delay faucet includes a main body shell 1, wherein the main body shell 1 has a side water outlet shell 11; A plastic core 2, internally connected to the main body shell 1, has a corresponding side wall water outlet 21. A water outlet 22 is sealed within the outlet 21 and extends along the interior of the side water outlet shell 11. A water outlet assembly 8 is fixed to the outer end of the water outlet 22. The external water source is sealed and connected to the lower part of the plastic core 2 via an external threaded pipe 4, forming a water inlet path 23. Figure 7-8 As shown, the external screw tube 4 simultaneously screws the internal plastic core 2 and the external main body shell 1, achieving simultaneous sealing and fixation with both. The main body shell 1 and the plastic core 2 are fixed to the table surface by a mounting base 5, a washer 6, a nut 7, etc.

[0015] The upper wall of the plastic core 2 is configured as a double-layer wall at the water outlet 21 to form a water outlet partition 24, wherein the outer wall 26 of the double-layer wall of the plastic core 2 is used to set the water outlet 21. A delay component 3, comprising, from bottom to top, a delay sleeve 31, a bushing 32 with a water passage gap 321, a sealing gasket 39, a valve core seat 33, and a delay handwheel 34 movably fitted above the valve core seat 33. The valve core seat 33 is locked to the upper part of the main body shell 1 and simultaneously sealed to the upper outer wall 26 of the plastic core 2, thereby fixing its position. Figure 7-8 As shown; a delay spring 35 is provided between the delay handwheel 34 and the valve core seat 33; The delay sleeve 31 is hung on the inner wall 25 of the double-layer wall of the plastic core 2, and its side wall has a water inlet 311. A delay sealing washer 37 is fixedly sleeved below a delay screw 36, which is close to the inner side wall of the delay sleeve 31 and can be displaced with the side wall of the delay sleeve 31 under axial force. A sealing ring 38 is fixedly sleeved above the delay sealing washer 37 on the delay screw 36 (in this embodiment, it is designed that an annular groove is opened on the side wall of the delay screw 36 to embed the sealing ring 38 into the annular groove for fixed sleeve). At the same time, the upper part of the delay screw 36 movably passes through the bushing 32, sealing gasket 39, valve core seat 33 and delay spring 35 and is further fixed to the delay handwheel 34. The delay screw 36 movably seals through the sealing gasket 39; Figure 8 As shown, the time-delay spring 35 expands or slightly compresses, causing the time-delay screw 36 to rise, and the sealing ring 38 abuts against the lower part of the bushing 32 to achieve a tight seal; the diameter of the portion of the time-delay screw 36 corresponding to the bushing 32 is smaller than that of the bushing 32; as Figure 7As shown, when the delay handwheel 34 is tightened, the delay spring 35 is compressed, and the sealing ring 38 moves downward away from the bushing 32. This allows water to flow from below the plastic core 2 through the inlet 311 on the side wall of the delay sleeve cup 31, and then through the gap 361 between the bushing 32 and the delay screw 36, further flowing into the outlet pipe 22 through the water passage 321 of the bushing 32 to achieve water output. As the delay spring 35 returns to its extended state, the sealing ring 38 presses against the bushing 32, returning to its original position. Figure 8 Status: Water outlet shut off.

[0016] like Figure 3-5 As shown, the bottom of the bushing 32 is an annular base 323. The annular base 323 is provided with several extended support bars 324 at intervals. The interval between each pair of extended support bars 324 is the water passage interval 321. The water passage interval 321 forms an arc-shaped groove slope 325 at the annular base 323, so that after passing through the water passage interval 321 of the bushing 32, the water flows along the arc-shaped groove slope 325 into the water outlet pipe 22, thereby ensuring the smooth flow of water and flowing out from the water outlet pipe 22.

[0017] like Figure 6 As shown, the valve core seat 33 is a seat body with a central through-hole, wherein a transverse annular partition 331 is provided inside, dividing it into an upper seat body 332 and a lower seat body 333. The lower seat body 333 has a double-layered annular wall extending downward longitudinally, namely an inner annular wall 334 and an outer annular wall 335. The inner annular wall 334 surrounds the mounting cavity, allowing the sealing gasket 39 and the extension support strip 324 of the bushing 32 to be built into and fixed therein, and the inner annular wall 334 abuts against the outer upper wall of the annular base 323 of the bushing 32. In this embodiment, the annular base 323 of the bushing 32 and the outer wall 26 of the extension support strip 324 are connected. A stepped edge 3231 is provided, allowing the inner ring wall 334 to abut against the stepped edge 3231 of the annular base 323 of the bushing 32, thereby achieving better positioning and sealing; the outer ring wall 335 is locked to the upper part of the main body shell 1, while the sealing sleeve is placed on the outer wall 26 of the plastic core 2 to achieve position fixation; thereby ensuring that the lower wall of the annular base 323 of the bushing 32 is partially sealed and clamped with the delay cup 31. In this embodiment, a concave ring is provided at the bottom of the annular base 323, which is suitable for a sealing ring to be placed inside the concave ring, so as to ensure that the lower wall of the annular base 323 is sealed and clamped with the extension cup through the sealing ring.

[0018] like Figure 7As shown, a water accumulation space 27 is formed between the valve core seat 33 and the bushing 32, and the water accumulation space 27 is connected to the water outlet partition 24. During use, when the user presses the delay handwheel 34, the delay spring 35 is compressed, and the sealing ring 38 follows the extension screw downwards away from the bushing 32. This allows the water flow below the plastic core 2 to enter through the inlet 311 on the side wall of the delay sleeve cup 31, and then further through the gap 361 between the bushing 32 and the delay screw 36, entering the water accumulation space 27 through the water passage 321 of the bushing 32. The water then flows through the water outlet partition 24 into the water outlet pipe 22 to achieve water outlet. Figure 7 As indicated by the arrow, as the delay spring 35 returns to its extended state, the sealing ring 38 presses against the bushing 32 to close the water outlet. In this embodiment, the delay sealing gasket 37 is a Y-shaped annular sealing gasket. The outwardly inclined annular portion 371 of the Y-shaped cross-section presses against the side wall of the delay cup 31, allowing it to move upward or downward under axial force while sealing. This ensures that during the process of the delay spring 35 returning to its extended state, the delay sealing gasket 37, under the pushing force of the delay spring 35, slowly moves upward against the side wall of the delay cup 31. When the sealing ring 38 presses against the bushing 32, the water outlet is closed, ultimately achieving the effect of delayed water outlet.

[0019] The above embodiments and illustrations are not intended to limit the product form and style of the present invention. Any appropriate changes and modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
