Description

Technical Field

[0001] The invention belongs to the technical field of bathroom water tank accessories, and in particular relates to a water replenishment amount distribution adjustable device in a toilet water tank accessory and a drain valve with the mechanism. Background Art

[0002] After the existing toilet completes a drainage flushing, it is necessary to replenish water to the water seal at the upper end of the S-bend pipe of the toilet to ensure that the S-bend pipe opening of the toilet is blocked by sufficient water surface, thereby preventing the sewage pipe from being connected to the bathroom, so as to isolate the odor from spreading into the room, and at the same time prevent harmful organisms in the sewage pipe from entering the room through the sewage pipe.

[0003] In the prior art, when the water inlet valve in the toilet water tank replenishes water into the water tank, part of the water inlet is drawn out through the water inlet valve, flows into the overflow pipe of the drain valve through various pipe connections, and finally flows into the water seal of the toilet to provide water for replenishment. Different toilet structures require different amounts of water, resulting in different amounts of water discharged by the two drainage gears of the drain valve, different amounts of water remaining in the toilet water seal, and different amounts of water replenished into the water tank by the water inlet valve, resulting in different amounts of water inlet and replenishment by the water inlet valve, which leads to the need to provide toilets with different gears with replenishment amounts that match the gears.

[0004] One of the technical solutions to the above problems in the prior art is to use throttling plugs of different sizes to partially block the water supply pipe of the water inlet valve. When the blocking area of ​​the throttling plug is larger, the flow cross-section of the water supply pipe is correspondingly smaller, so that the water supply amount is also smaller, and vice versa.

[0005] The second technical solution to the above problem in the prior art is to hang an independent regulating and replenishing water device on the overflow pipe of the drain valve. The water replenishing device adjusts the amount of water replenished to the toilet water seal by blocking the water replenishing pipe. The purpose of adjusting the water replenishing amount is achieved by adjusting different blocking areas to change the flow cross-section of the water replenishing pipe.

[0006] The third technical solution to the above-mentioned problem in the prior art is to hang a float switch mechanism on the overflow pipe of the drain valve. The mechanism has a float that can float up and down with the changes in the water level inside the water tank. The height of the float in the water tank is adjusted by an adjustment ruler on the float itself. A control switch is connected to the upper end of the float, and the water supply pipe channel of the water inlet valve is connected to the switch. When the water level in the water tank changes, the floating height and time of the float of the water supply mechanism at different water level heights in the water tank are different, and the opening time of the water supply switch on the control float is different, thereby achieving the purpose of controlling the amount of water supplied to the water seal of the toilet by the water inlet valve.

[0007] However, the above three solutions all require the use of multiple adjustment mechanisms, and multiple water volume control devices need to be installed on the water inlet valve and the drain valve in the water tank at the same time. Many parts are used, and the installation and operation are cumbersome. It is easy to lose parts and make operating errors, resulting in waste. The water replenishment ratio is also not easy to adjust quickly. Summary of the invention

[0008] The technical problem to be solved by the present invention is to provide an adjustable water replenishment distribution device which is integrated with a drain valve, does not require excessive water replenishment parts, does not require additional installation steps in the water tank, and has a simple and fast adjustment process.

[0009] In order to solve the above problems, the technical solution adopted by the present invention is: a water replenishment amount distribution adjustable device, including a distribution body, the distribution body is provided with a water inlet chamber and a water distribution chamber, the water inlet chamber is provided with a water replenishment inlet, the water distribution chamber is provided with a water replenishment outlet, the replenishment water flows into the water inlet chamber through the water replenishment inlet, is switched by the conversion rod in the water inlet chamber, and then the water volume is adjusted by the adjustment knob on the water distribution chamber, and flows out from the water replenishment outlet. The water replenishment inlet is connected to the water inlet valve through the water replenishment water channel, and the water replenishment outlet is connected to the overflow pipe through the water replenishment pipe and the water replenishment cap, so that the water replenishment water flow is introduced into the water seal of the toilet for water replenishment.

[0010] Preferably, the conversion rod is sleeved on the fixed column in the water inlet chamber to form a rotational connection with the fixed column, and sealing surfaces are respectively provided at both ends of the conversion rod, and the sealing surfaces include full-row sealing surfaces and half-row sealing surfaces. The switching piston rod includes a full-row switching piston rod and a half-row switching piston rod. The heads of the full-row switching piston rod and the half-row switching piston rod are respectively provided with full-row pins and half-row pins, and the full-row pins are sleeved in the full-row pin grooves on the conversion rod; the half-row pins are sleeved in the half-row pin grooves on the conversion rod, and the switching piston rod drives the sealing surfaces at both ends of the conversion rod to perform reciprocating motion.

[0011] Preferably, the water diversion chamber is provided with two water inlet holes connected to the water inlet chamber, namely, a full-row water inlet hole and a half-row water inlet hole. The full-row water inlet hole and the half-row water inlet hole are respectively provided with water replenishment ports connected to the water inlet chamber and the water diversion chamber, namely, a full-row water replenishment port and a half-row water replenishment port. The full-row water inlet hole and the half-row water inlet hole are respectively installed with rotatable adjustment knobs, and the adjustment knobs are provided with adjustment ports coordinated with the water replenishment ports.

[0012] Preferably, a convex point is provided on the lower end surface of the adjusting knob, and a plurality of positioning grooves are provided on the upper end surface of the water inlet hole. The convex point is matched with the positioning groove, and the size of the convex point is slightly smaller than the size of the positioning groove.

[0013] Another technical problem to be solved by the present invention is to provide a drain valve with an adjustable water replenishment amount distribution device, including the adjustable water replenishment amount distribution device and a button for driving the adjustable water replenishment amount distribution device, and the adjustable water replenishment amount distribution device and the button are integrated into one.

[0014] Preferably, the button includes a full-row button and a half-row button. A full-row button driving surface is provided at the bottom of the full-row button, and a half-row button driving surface is provided at the bottom of the half-row button. The half-row button driving surface fits and slides with the half-row piston push surface at the tail of the half-row switching piston rod; similarly, the full-row button driving surface fits and slides with the full-row button push surface at the tail of the full-row switching piston rod. That is, the button transmits the downward force to the switching piston rod through the button driving surface, so that the downward movement of the button is converted into the lateral movement of the switching piston rod, and the forward linear movement of the switching piston rod drives the conversion rod connected to the piston rod to perform selective rotational movement, so that the two sealing surfaces of the conversion rod change their relative positions relative to the two water inlet holes, and one sealing surface seals and covers while the other sealing surface gives way and opens, so as to realize the switching of the flow of different water inlet holes.

[0015] It can be seen that the adjusting knob on the distribution body is not directly connected to the water flow of the water inlet valve. After the water flow of the water inlet valve enters the water inlet chamber, it reaches the water distribution chamber after being adjusted by the flow area of ​​the adjusting knob. The water supply pipe is not directly connected to the adjusting knob. It passes through the water distribution chamber and the water supply outlet and then flows into the overflow pipe. The adjusting knob is respectively connected to the water inlet chamber and the water distribution chamber, so that the water distribution chamber and the water inlet chamber are not directly connected together.

[0016] The size of the protrusion of the adjusting knob is slightly smaller than the design of the positioning groove of the distribution body. The purpose is that when the adjusting knob is turned, the protrusion slides in and out of the positioning groove, so that the adjusting knob produces a small up and down motion feedback.

[0017] Due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0018] 1. Without directly changing the cross-section of the water supply port of the water inlet valve, the amount of water supply can be adjusted by only adjusting the position of the adjusting knob of the water supply amount distribution adjuster on the drain valve. The structure is simple and the influence of pressure fluctuations caused by direct blockage of the water supply port of the water inlet valve on the water supply amount can be avoided, and the water supply amount is stable.

[0019] 2. Through the conversion action of the conversion rod, the water replenishment volume distribution adjuster is linked with the full-drain and half-drain buttons of the drain valve. The two drainage gears of the drain valve are automatically switched to the required water volume respectively, so that the drain valve can be suitable for the water replenishment needs of different toilets, which improves the use range of the drain valve and avoids waste of water resources.

[0020] 3. Due to the existence of the water inlet chamber and the water diversion chamber, the water flow of the water inlet valve does not flow directly to the adjusting knob, and the water flow out of the adjusting knob does not flow directly to the water supply pipe. When the water flow of the water inlet valve changes, the water inlet chamber can play a certain buffering role due to the water storage in the cavity inside the water inlet chamber. Due to the existence of the water diversion chamber, the water flow of the water supply outlet will not change drastically due to the change of the flow area of ​​the adjusting knob, which will cause the water flow of the water supply pipe to impact the wall of the overflow pipe to produce large splashes and noise, affecting the user's experience.

[0021] Fourth, due to the presence of the convex points on the adjustment knob and the positioning grooves of the distribution body, personnel can get clear feedback when adjusting the water replenishment ratio. BRIEF DESCRIPTION OF THE DRAWINGS

The full-row adjusting knob 21 and the half-row adjusting knob 20 can rotate in the water inlet hole under the action of external force.

[0062] A fixing column 6 and a conversion rod 4 are installed in the water inlet chamber 101. The conversion rod 4 includes a full row of pin grooves 401, a full row of sealing surfaces 403, a half row of pin grooves 402, a half row of sealing surfaces 404 and a fixing hole 405. The conversion rod 4 is mounted on the fixing column 6 through the fixing hole 405 on itself and can rotate on the fixing column 6.

[0063] The distribution body 1 is sealed together with the sealing end cover 3 by ultrasonic welding, and the full-row switching piston rod 7 and the half-row switching piston rod 5 are arranged through the through hole of the sealing end cover 3 and can slide back and forth in the through hole. The full-row switching piston rod 7 and the half-row switching piston rod 5 are respectively provided with a full-row latch 702 and a half-row latch 502 at the head, and the full-row latch 702 is sleeved in the full-row latch groove 401 on the conversion rod 4; the half-row latch 502 is sleeved in the half-row latch groove 402 on the conversion rod 4; the full-row sealing surface 403 and the half-row sealing surface 404 of the conversion rod 4 are made of secondary injection-molded soft rubber material; the full-row switching piston rod 7 and the half-row switching piston rod 5 are installed together through the conversion rod 4, and the full-row sealing surface 403 and the half-row sealing surface 404 are tightly attached to the partition of the water inlet chamber 101.

[0064] A drain valve with an adjustable water replenishment amount distribution device of the present invention comprises a button seat 10, on which a half-row button 8 and a full-row button 9 are installed, and a half-row button driving surface 801 is provided on the half-row button 8, and the half-row button driving surface 801 can be fitted with a half-row piston push surface 501 at the tail of a half-row switching piston rod 5; similarly, a full-row button driving surface 901 is provided on the full-row button 9, and the full-row button driving surface 901 is fitted with a full-row button push surface 701 at the tail of a full-row switching piston rod 7. The half-row button 8 and the full-row button 9 are mounted on the button seat 10 through two springs for rebounding and the buckles of the buttons themselves.

[0065] The water replenishment inlet 12 of the present invention is connected to the water inlet valve (not shown) in the toilet water tank through a water replenishment pipe (not shown). The water replenishment outlet 13 is connected to one end of the water replenishment pipe 15, and the other end of the water replenishment pipe 15 is installed on the water replenishment cap 14, and the water replenishment cap 14 is mounted on the overflow pipe 16. At this time, the water distribution chamber 102 of the adjustable water replenishment amount distribution device 11 is connected to the overflow pipe 16 through the water replenishment outlet 13, the water replenishment pipe 15 and the water replenishment cap 14. The overflow pipe 16 is connected to the water seal through the internal water channel of the toilet, so that the replenishment of the water inlet valve can flow to the water seal of the toilet through the entire drain valve with the adjustable water replenishment amount distribution device 11.

[0066] In order to adjust the replenishment water flow in the half-row and full-row gears of the double-speed drain valve according to the needs after the product leaves the factory, the replenishment water flow ratio of the replenishment water quantity distributor 11 is designed to be adjustable, that is, the replenishment water flow can be realized in the full-row water inlet hole 1011, the half-row water inlet hole 1021 and the half-row adjusting knob 20, and the full-row adjusting knob 21 of the water diversion chamber 102. The flow area ratio of the half-row water inlet hole 1021 and the full-row water inlet hole 1011 of the water diversion chamber 102 is blocked by adjusting the half-row adjusting port 201 and the full-row adjusting port 211 leading to the adjusting knob, so as to adjust the diversion ratio of the replenishment water flow flowing into the water diversion chamber 102 and flowing to the outside of the replenishment outlet 13.

[0067] The water flow route and the water replenishment switching method of the two gears of this embodiment are as follows:

[0068] When the user presses the full-row button 9 on the drain valve, the full-row button 9 moves in the direction of the compression spring under the action of external force, while the half-row button 8 remains stationary due to the absence of external force; when the full-row button 9 moves to a certain position, the full-row button driving surface 901 on the full-row button 9 contacts the full-row button pushing surface 701 at the tail of the full-row switching piston rod 7, and when the full-row button 9 continues to move with the compression spring, the full-row button driving surface 901 squeezes the full-row button pushing surface 701 due to the action of the external force following the full-row button 9, so that the full-row switching piston rod 7 is squeezed by the full-row button 9 and moves toward the full-row water inlet hole 1011 close to the water inlet chamber 101; at the same time, since the full-row pin slot 401 of the conversion rod 4 is sleeved on the full-row switching piston rod 7 The full-row plug 702 is inserted into the full-row plug 702, so the forward movement of the full-row switching piston rod 7 is driven by the full-row plug 702, so that the conversion rod 4 also begins to rotate in the direction close to the full-row water inlet hole 1011. When the full-row button 9 moves to the final position, the full-row switching piston rod 7 is continuously squeezed by the full-row button 9, driving the full-row sealing surface 403 of the conversion rod 4 to move to the full-row water inlet hole 1011 of the water inlet chamber 101, so that the full-row sealing surface 403 of the switching rod 4 completely covers the full-row water inlet hole 1011 of the water diversion chamber 102, and because the full-row sealing surface 403 itself is made of soft rubber material, the full-row water inlet hole 1011 is completely sealed by the full-row sealing surface 403, so that water cannot flow from the full-row water inlet hole 1011 to the water diversion chamber 102.

[0069] When the user removes the external force, the rebound spring of the full-row button 9 is in a compressed state, driving the full-row button 9 to return to its initial position, and the full-row button driving surface 901 of the full-row button 9 disengages from the full-row button pushing surface 701 of the full-row switching piston rod 7, and the full-row switching piston rod 7 stops moving and remains in the final position, so that the full-row sealing surface 403 stays on the full-row water inlet hole 1011.

[0070] Since the conversion rod 4 can only rotate around the fixed column 6, when the full-row sealing surface 403 of the conversion rod 4 moves toward the full-row water inlet hole 1011, the half-row sealing surface 404 at the other end of the conversion rod 4 moves away from the half-row water inlet hole 1021. When the full-row sealing surface 403 reaches above the full-row water inlet hole 1011, the half-row sealing surface 404 on the conversion rod 4 is completely away from the half-row water inlet hole 1021, resulting in the half-row water inlet hole 1021 without any obstruction, so that the water inlet chamber 101 and the water diversion chamber 102 are connected together through the half-row water inlet hole 1021.

[0071] The replenishing water flow from the water replenishing port of the water inlet valve flows to the replenishing inlet 12 of the distribution body 1 through the replenishing pipe (not shown) and reaches the water inlet chamber 101. Since only the half-row water inlet holes 1021 are in the state of being connected to the water diversion chamber 102 at this time, the replenishing water flow passes through the half-row water inlet holes 1021 and flows into the water diversion chamber 102 through the half-row adjusting port 201 of the adjusting knob 2; since the water diversion chamber 102 is connected to the overflow pipe 16 of the drain valve through the replenishing pipe 15, the replenishing water flow of the water inlet valve can only flow to the overflow pipe 16 of the drain valve through the half-row water inlet holes 1021, so that when the full-row gear is drained, the full-row replenishment of the water inlet valve is achieved.

[0072] Similarly, when the user presses the half-row button 8, the half-row sealing surface 404 of the conversion rod 4 is driven by the button to move to the half-row water inlet hole 1021, so that the full-row water inlet hole 1011 is always in an open state. At this time, the water flow of the entire drain valve flows through the full-row water inlet hole 1011 to the overflow pipe 16, and finally reaches the water seal of the toilet, so that when the half-row gear is drained, the half-row of the water inlet valve replenishes water separately. The specific movement method is not repeated here.

[0073] From the above movement description, it can be seen that by using buttons of different gears, the water flow channel of that gear can be automatically opened without the customer having to perform any further operations.

[0074] The water replenishment amount adjustment process of this embodiment is as follows:

[0075] In the non-water replenishing state, the adjusting knob 2 is driven to rotate. Since the convex point 200 of the adjusting knob 2 is located in the positioning groove 1033 of the distribution body 1 at this time, under the action of external force, the convex point 200 of the adjusting knob slides out of the positioning groove 1033 of the distribution body 1 along the arc surface away from the bottom surface of the arc, and at the same time drives the adjusting knob 2 to produce a small upward movement. Continue to apply external force, and the adjusting knob 2 continues to drive the convex point 200 to rotate. When the convex point 200 reaches the top of the next positioning groove 1033 of the distribution body 1, the convex point 200 of the adjusting knob 2 is in a state similar to being suspended. Under the action of external force, the convex point 200 moves toward the arc bottom of the positioning groove 1033 at this position, and at the same time, the adjusting knob 2 produces a small downward movement. Similarly, continuing to rotate the adjusting knob 2 can make the adjusting knob 2 form an intermittent up and down movement relative to the surface of the distribution body 1, which is then fed back to the user's sensor system, thereby strengthening the user's judgment on the required adjustment position.

[0076] Taking the half-row water replenishment water volume adjustment as an example, in the initial state, the half-row adjustment port 201 of the half-row adjustment knob 20 and the full-row water replenishment port 1031 of the distribution body 1 are not blocked by anything, that is, the full-row water replenishment port 1031 is completely in an open state, and the water replenishment ratio of the half-row gear is 100%; when the half-row water replenishment ratio needs to be adjusted, the half-row adjustment knob 20 is rotated, and the half-row adjustment knob 20 rotates in the full-row water inlet hole 1011 of the distribution body 1, so that the area of ​​the full-row adjustment port 1031 blocked by the half-row adjustment port 201 is increased, thereby reducing the flow area of ​​the water flow, thereby achieving the goal of reducing the water replenishment ratio of the half-row gear; continue to rotate the half-row knob 20, when the half-row adjustment port 201 of the half-row knob 20 is completely away from the full-row water replenishment port 1031, that is, the full-row water replenishment port 1031 is completely blocked, the water flow is completely closed, and the water replenishment ratio is 0. Rotating the half-row adjustment knob 20 in the opposite direction can increase the flow area of ​​the full-row water replenishment port 1031, thereby obtaining a larger water replenishment ratio for the half-row gear position.

[0077] Similarly, by rotating the full-row adjustment knob 21 , the water flow area of ​​the corresponding half-row adjustment port 1032 can be changed to obtain the corresponding water replenishment ratio.

[0078] The examples of the present invention are described in detail above, but the present invention is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. All changes and improvements made within the scope of the present invention are still within the protection of the present invention.
