Description

Technical Field

[0001] The utility model relates to the field of flush toilets, in particular to a ceramic chip water-sealing toilet inlet valve. Background Technique

[0002] A flush toilet is a common device in modern family bathrooms. It utilizes the principles of gravity and kinetic energy of water. The water in the water tank quickly flushes into the toilet bowl, forming a strong impact force to effectively wash away dirt. This toilet design aims to maintain the cleanliness and hygiene of the bathroom and improve the quality of life. Flush toilets are not only convenient to use, but also with the progress of technology, many products have added intelligent functions such as water saving, odor prevention, and heated seat rings, making the use experience more comfortable and environmentally friendly.

[0003] The toilet inlet valve is an important component in a flush toilet, responsible for controlling the flow rate and speed of water entering the water tank to ensure that the water tank can maintain an appropriate water level for flushing.

[0004] The current toilet inlet valve usually uses a sealing gasket with a sealed opening to control the water inlet of the toilet. However, the sealing gasket has a certain elasticity, so it has relatively high requirements for water pressure. When the water pressure is low, the water may not be able to pass through the opening of the sealing gasket. But when the water pressure is increased, the water may directly flush open the opening at the top of the sealing gasket, resulting in continuous water inflow inside the toilet water tank. Therefore, the sealing gasket needs the water inlet pressure to be within a certain range to ensure normal operation, which is rather troublesome to use. For this reason, a ceramic chip water-sealing toilet inlet valve is proposed to solve the above problems. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a ceramic chip water-sealing toilet inlet valve, aiming to improve the problem that the sealing gasket in the prior art needs the water inlet pressure to be within a certain range to ensure normal operation.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Refer to Figures 1 - 3 As shown in the figure, an embodiment provided by the present invention: A water inlet valve for a ceramic chip sealed water toilet includes a water outlet pipe 1. The bottom of the water outlet pipe 1 has a relatively low opening, which can prevent water from splashing and reduce the sound of adding water when adding water inside the water tank. A sliding sleeve 2 is arranged on the outer periphery of the water outlet pipe 1. By adjusting the position of the sliding sleeve 2, the position of the float box 3 can be adjusted. The sliding sleeve 2 is fixedly connected to the float box 3 on the right side. A float 4 is slidably connected inside the float box 3. The float box 3 is used to limit the lowest position of the float 4. A float rod 5 is arranged inside the float 4. The top of the float rod 5 is connected by a pin to a connecting rod 6 for connection. A sliding groove is arranged at the outer hinged end of the connecting rod 6 to facilitate the sliding of the pin. The bottom of the inner end of the connecting rod 6 is fixedly connected to a supporting column 7. The bottom of the supporting column 7 is fixedly connected to a ceramic plug core 8. The bottom of the ceramic plug core 8 contacts a water passing core 9. There is a good sealing performance between the ceramic plug core 8 and the water passing core 9. When the ceramic plug core 8 abuts against the top of the water passing core 9, water cannot pass through. An inlet hole 10 for facilitating water inlet is opened inside the water passing core 9.

[0037] Refer to Figures 2 - 3, a water inlet assembly is fixedly connected to the outer periphery of the water passing core 9. The water inlet assembly is used to connect to an external water pipe to add water into the water tank. The water inlet assembly includes a fixing seat 11 that serves as a fixing connection. The fixing seat 11 is fixedly connected to the water passing core 9 inside. The top of the fixing seat 11 is fixedly connected to a connecting seat 12 that serves as a fixing connection. The bottom of the connecting seat 12 is fixedly connected to the top of the water outlet pipe 1. A water outlet hole 13 is provided on the outer periphery of the fixing seat 11. There are several groups of water outlet holes 13, which are evenly distributed in a ring inside the fixing seat 11. The water outlet holes 13 are located above the water passing core 9. After the water enters through the water inlet hole 10 inside the water passing core 9, it is discharged into the water outlet pipe 1 through the water outlet holes 13. The bottom of the fixing seat 11 is fixedly connected to a water inlet pipe 14, and the bottom of the water inlet pipe 14 is connected to an external water network. A protective cover 15 is detachably connected to the top of the water inlet assembly. The bottom of the protective cover 15 is detachably connected to the outer periphery of the connecting seat 12. The inner end of the connecting rod 6 is hinged to the bottom of the protective cover 15, so that the pressure of the connecting rod 6 on the ceramic plug core 8 is relatively large, ensuring the sealing performance. A through groove 16 is provided on the right side of the protective cover 15, and the connecting rod 6 is arranged inside the through groove 16.

[0038] Referring to Figure Figures 4 - 6 , the floating cylinder 4 includes a floating cylinder body 41. A sliding groove 43 is provided at the bottom of the floating cylinder body 41. The outer edge of the float box 3 is slidably connected inside the sliding groove 43. The top of the floating cylinder body 41 is arranged on the outer periphery of the floating rod 5. When the floating cylinder body 41 floats or descends, the floating cylinder body 41 will drive the floating rod 5 to move together. The floating rod 5 is located inside the sliding groove 43. A floating groove 42 is provided at the bottom of the floating cylinder body 41. After the water enters the floating groove 42, it will push the floating cylinder body 41 to rise upward. A water collecting groove 44 is provided at the top of the floating cylinder body 41. A one-way valve assembly is provided on the inner wall of the bottom end of the water collecting groove 44. The one-way valve assembly is used for one-way water passing. The one-way valve assembly includes a sliding sleeve 17. An opening is provided at the bottom end of the sliding sleeve 17. The outer periphery of the sliding sleeve 17 is fixedly connected to the inner wall of the bottom end of the water collecting groove 44. A communication hole 18 is provided on the outer periphery of the sliding sleeve 17. The communication hole 18 connects the inside of the sliding sleeve 17 with the inside of the water collecting groove 44. A floating core 19 is slidably connected inside the sliding sleeve 17. The floating core 19 has buoyancy, and the water can lift the floating core 19.

[0039] Working principle: When there is water inside the toilet tank, the water lifts the float 4 upward, and the float 4 lifts the float rod 5. The float rod 5 drives the outer end of the connecting rod 6 to rise. At this time, the inner end of the connecting rod 6 is pressed downward, driving the column 7 to press downward, and the ceramic plug 8 is firmly pressed on the top of the water core 9. At this time, the water in the water inlet pipe 14 cannot enter the interior of the connecting seat 12 and cannot flow out. When the water is released, the water level drops, driving the float 4 to drop, and the float 4 drives the outer end of the connecting rod 6 to drop, and the inner end of the connecting rod 6 is lifted, driving the top of the column 7 to lift, and the column 7 drives the ceramic plug 8 to slide along the upper left, exposing the water inlet hole 10. At this time, water will enter the interior of the connecting seat 12 from the inside of the water inlet pipe 14, and enter the interior of the water outlet pipe 1 from the inside of the water outlet hole 13, and enter the toilet tank. When there is water in the water tank, the buoyancy of the water will lift the float core 19, and the float core 19 will slide upward along the sliding sleeve 17, allowing water to enter the inside of the water collection tank 44 through the connecting hole 18. When the water level drops, the float core 19 moves downward along the sliding sleeve 17. At the same time, the water in the water collection tank 44 presses the float core 19, making it unable to float up, thereby closing the connecting hole 18. At this time, the water in the water collection tank 44 cannot be discharged, which increases the deadweight of the float 4, allowing the float 4 to drop quickly, thereby quickly opening the water core 9 to discharge water.

[0040] Example 2:

[0041] Reference Figures 7 - 9 The difference between Example 2 and Example 1 is that a left-right symmetrical water inlet hole 10 is opened inside the water core 9, and the top of the water core 9 contacts the ceramic plugging core 8. The ceramic plugging core 8 is formed by two left-right symmetrical fan-shaped connections. When the fan-shaped ceramic plugging core 8 is opposite to the water inlet hole 10, the water inlet hole 10 can be sealed. When the ceramic plugging core 8 is rotated ninety degrees, the water inlet hole 10 can be fully opened. The top of the ceramic plugging core 8 is provided with two groups of left-right symmetrical clamping grooves 20, and a rotating clamping block 21 is clamped inside the clamping groove 20. The top of the rotating clamping block 21 is fixedly connected to a rotating column 22. The outer periphery of the rotating column 22 is rotatably connected to a limit cover 23. The side wall of the limit cover 23 is provided with a through hole that allows water to pass through. The limit cover 23 is fixedly connected to the inside of the connecting seat 12. The top of the rotating column 22 is rotatably connected to a rotating bracket 24. The top of the connecting rod 6 is hinged on the inner wall of the top of the rotating bracket 24. When the water inside the water tank is full, the connecting rod 6 is low inside and high outside. The connecting rod 6 is fixedly connected to a dial rod 25 at the inner bottom end. The dial rod 25 is perpendicular to the connecting rod 6 at ninety degrees. The top outer end of the rotating column 22 is hinged to a dial plate 26. A dial through hole 27 is provided inside the dial plate 26. The inner diameter of the dial through hole 27 is larger than the diameter of the dial rod 25, so that the dial rod 25 has space to move inside the dial through hole 27.

[0042] Working principle: When the water level drops, the buoy 4 drops, the buoy 4 drives the float rod 5 to drop, the float rod 5 drives the outer side of the connecting rod 6 to move downward, the connecting rod 6 rotates along the hinge point with the rotating bracket 24, drives the bottom of the shifting rod 25 to grab and move, the shifting rod 25 slides inside the shifting through hole 27, pushes the shifting plate 26 to rotate, the shifting plate 26 drives the rotating column 22 to rotate, the rotating column 22 drives the rotating locking block 21 to rotate, the rotating locking block 21 drives the ceramic plug core 8 at the top to rotate, the ceramic plug core 8 rotates on the water passing core 9, so that the water inlet hole 10 is exposed, water enters the inside of the limit cover 23 from the inside of the water inlet pipe 14, then flows out from the through hole on the limit cover 23, enters the water outlet pipe 1 through the water outlet hole 13, and then enters the inside of the water tank from the water outlet pipe 1, completing the water injection into the water tank.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
