Description

Technical Field

[0001] This invention is a quick-switching toilet flushing device, belonging to the sanitary ware industry. Background Technology

[0002] Existing toilets generally use the potential energy of water in the tank to flush away waste in the toilet bowl.

[0003] A toilet flush cycle should typically serve three purposes: first, to remove waste from the toilet bowl into the drain pipe; second, to clean the bowl walls to remove any solid or liquid waste deposited or attached to the bowl surface; and third, to replenish the water seal, leaving relatively clean water in the toilet between uses and ensuring sufficient water seal to prevent sewer odors from entering the room.

[0004] To achieve the above objectives, existing technologies generally use two pre-reserved water outlet structures to interact, allowing water in the tank to flow out in batches.

[0005] In existing technologies, there are two types of water outlet structures where the pressure relief holes are not blocked, resulting in a switching delay, which is particularly noticeable when the water tank is short and wide. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a toilet flushing device with rapid switching to solve the problem.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: a quick-switching toilet flushing device, installed in a toilet tank; the flushing device includes a water inlet for water supply, multiple flush ports connected to the water inlet, and a valve unit for switching the water output of the flush ports; the valve unit has chambers respectively connected to the flush ports, and its water inlet pipe is respectively connected to these chambers.

[0008] The valve unit includes individual valve components for controlling the opening and closing of the communication channel between the punch and the chamber, and a linkage switch structure for opening one valve component when the other valve component is closed.

[0009] The device has two flushing ports and two flushing chambers, namely an upper flushing port and a lower flushing port, and an upper chamber and a lower chamber; the upper chamber is first connected to the water inlet and then connected to the lower chamber through a connecting pipe;

[0010] The linkage switch structure switches the valve assembly based on the water level in the toilet tank; the valve assembly includes an upper diaphragm valve; the upper diaphragm valve has a pre-reserved rear chamber; when the upper diaphragm valve is retracted to the rear chamber by the linkage switch structure, the communication channel between the upper flush port and the upper chamber will be opened.

[0011] The valve assembly includes a lower diaphragm valve; a rear chamber for the lower diaphragm valve is reserved on the rear side of the lower diaphragm valve; when the lower diaphragm valve is retracted to the rear chamber by the action of the linkage switch structure, the communication channel between the lower punch and the lower chamber will be opened;

[0012] The linkage switch structure includes an upper pressure relief hole and an upper pressure boosting hole communicating with the rear chamber of the upper diaphragm valve, a lower pressure relief hole communicating with the rear chamber of the lower diaphragm valve, a connecting component for adjusting the internal pressure of the rear chamber of the upper diaphragm valve, and an external component for adjusting the internal pressure of the rear chamber of the lower diaphragm valve.

[0013] When its external component presses against the lower pressure relief hole, the lower diaphragm valve's rear chamber is under positive pressure; the connecting component is installed on the lower diaphragm valve, and when the lower diaphragm valve's rear chamber is under positive pressure, the connecting component will press against the upper pressure boosting hole, and then the upper pressure relief hole will release pressure to the upper diaphragm valve's rear chamber, thereby causing the upper diaphragm valve to retract to the upper diaphragm valve's rear chamber;

[0014] When the external component detaches from the pressure relief hole, the lower diaphragm valve rear chamber is in a pressure relief state, causing the lower diaphragm valve to retract to the lower diaphragm valve rear chamber;

[0015] The flushing device includes a housing for mounting valve assemblies;

[0016] The housing includes a limiting portion for engaging the valve assembly, which causes the valve assembly to be raised in the direction of the water flow, and the raised valve assembly provides sufficient space for retraction under force.

[0017] The width occupied by the upper diaphragm valve post-position chamber and the lower diaphragm valve post-position chamber is equal to half the thickness of the diaphragm valve in the valve assembly.

[0018] Preferably, the water inlet is a water inlet pipe connected to a water pump for pumping water.

[0019] Preferably, the connecting assembly includes a horizontal shaft mounted on the lower diaphragm valve, a spring for holding the horizontal shaft in place, and a first rubber pad located on the horizontal shaft; the first rubber pad will hold the upper pressure port in place.

[0020] Preferably, the external assembly includes a float, a screw, and a swing arm; the float is mounted on the screw shank by fasteners; the swing arm is snapped onto the end of the screw and a distance is reserved for the swing arm to swing; the swing arm is mounted on the valve unit by a hinge, and a second rubber pad is provided at the lower pressure relief hole of the swing arm to seal the lower pressure relief hole.

[0021] Preferably, the diameter of the upper pressure boosting hole is larger than that of the upper pressure relief hole.

[0022] Beneficial effects

[0023] This invention achieves the switching of two valve components through a corresponding linkage switch structure. The effect is that when one valve component is opened, the other valve component will be closed immediately without delay. The switching speed is fast, there is no waste of water force, and the flushing effect is greatly improved. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] Please see Figure 1-4 A quick-switching toilet flushing device is installed in a toilet tank. Its structure includes a water inlet for water supply, a flushing port connected to the water inlet, and a valve unit for switching the water output from the flushing port. The valve unit has chambers that are respectively connected to the flushing ports, and its water inlet pipe 1 is respectively connected to these chambers to form a communication channel.

[0031] The water inlet is a water inlet pipe 1, which is connected to a water pump 11 for pumping water. The water pump 11 pumps water into the water inlet pipe 1. There are two flushing ports and two chambers, namely an upper flushing port 2 and a lower flushing port 3, and an upper chamber and a lower chamber. The upper chamber is first connected to the water inlet pipe 1 and then connected to the lower chamber through a U-shaped pipe. Thus, the upper chamber and the upper flushing port 2 form a connecting channel A, and the lower chamber and the lower chamber form a connecting channel B.

[0032] The valve unit includes individual valve components for controlling the opening and closing of the communication channel between the punch and the chamber, and a linkage switch structure for opening one valve component when the other valve component is closed.

[0033] The valve assembly includes an upper diaphragm valve 41 disposed in the communication channel A; the upper diaphragm valve 41 has a rear chamber 410 reserved on its rear side; when the upper diaphragm valve 41 is retracted to the rear chamber 410 by the action of the linkage switch structure, the communication channel A between the upper flush port 2 and the upper chamber will be opened, so that the water flow in the water inlet pipe 1 will be discharged smoothly from the upper flush port 2 without being blocked by the upper diaphragm valve 41;

[0034] The valve assembly also includes a lower diaphragm valve 42 disposed in the connecting channel B; a lower diaphragm valve rear chamber 420 is reserved on the rear side of the lower diaphragm valve 42; when the lower diaphragm valve 42 is retracted to the lower diaphragm valve rear chamber 420 by the action of the linkage switch structure, the connecting channel B between the lower flush port 3 and the lower chamber will be opened, so that the water flow in the water inlet pipe 1 will be discharged smoothly from the upper flush port 2 without being blocked by the lower diaphragm valve 42;

[0035] Furthermore, the width occupied by the upper diaphragm valve rear chamber 410 and the lower diaphragm valve rear chamber 420 is approximately equal to half the thickness of the diaphragm valve in the valve assembly. In this way, when the upper diaphragm valve 41 and the lower diaphragm valve 42 are retracted, firstly, sufficient space can be reserved for them to retract so that the water flow can pass smoothly, and secondly, during the reset process (closed valve state), leakage is prevented because the diaphragm valve is not tightly attached to the channel opening.

[0036] The linkage switch structure includes an upper pressure relief hole 4102 and an upper pressure boosting hole 4101 communicating with the upper diaphragm valve rear chamber 410, a lower pressure relief hole 4201 communicating with the lower diaphragm valve rear chamber 420, a connecting component for adjusting the internal pressure of the upper diaphragm valve rear chamber 410, and an external component for adjusting the internal pressure of the lower diaphragm valve rear chamber 420.

[0037] The connecting assembly includes a horizontal shaft 432 mounted on the lower diaphragm valve 42, a spring 431 for pressing against the horizontal shaft 432, and a first rubber pad 433 located on the horizontal shaft 432. The first rubber pad 433 will press against the upper pressure hole 4101. The diameter of the first rubber pad 433 is larger than that of the upper pressure hole 4101 so that it can be completely aligned and covered to seal it. The first rubber pad 433 is snapped onto the horizontal shaft 432 by a concave-convex structure, so that the first rubber pad 433 can be easily replaced after it ages.

[0038] The external components include a float 442, a screw 443, and a swing arm 441. The float is mounted on the screw shank with fasteners, which are commonly five-piece components. The position of the float can be adjusted according to the position of the mounting threads to use different water tank levels. The swing arm 441 is snapped into the end of the screw shank with a reserved distance for swinging. The swing arm 441 is hinged to the valve unit, and a second rubber pad 444 is provided at the corresponding lower pressure relief hole 4201 to seal the lower pressure relief hole 4201. The float 442 is preferably filled with foam to provide strong buoyancy to facilitate the sealing of the lower pressure relief hole 4201 by the swing arm 441. Similarly, the swing arm 441 and the second rubber pad 444 are also snapped together with a concave-convex structure for easy replacement after aging.

[0039] The upper diaphragm valve 41 and lower diaphragm valve 42 are structured as follows: an elastic and waterproof annular diaphragm 413, a mounting component 412 installed at the center of the annular diaphragm 413, and a pressure boosting component 411 installed on the mounting component 412. The annular diaphragm 413 is secured to the valve unit housing to prevent it from falling off. A limiting ring is provided along the outer edge of the annular diaphragm 413, and the housing holds this limiting ring to prevent the annular diaphragm 413 from falling off under pressure. The housing can be secured using hardware components such as front and rear clamps, allowing for removal and replacement of the annular diaphragm 413 after aging. The annular diaphragm 413 is raised after installation, providing better elasticity and facilitating repositioning under stress. The mounting component 412... The device is installed at the center of the annular diaphragm by clamping. This clamping method involves setting a protrusion at the center of the annular diaphragm 413, and the mounting part 412 is provided with a groove corresponding to the protrusion, using the concave-convex structure for fixation. The pressure booster 411 is snapped onto the mounting part 412 to form a cavity with only one opening. In this way, when water flows into the cavity during impact, the force can be better transmitted to the upper diaphragm valve 41. The cavity of the pressure booster 411 in the lower diaphragm valve 42 contains a spring 431 and a horizontal shaft 432, which can limit the horizontal shaft 432 so that the first rubber pad 433 on the horizontal shaft 432 can accurately press against the upper pressure boosting hole 4101. The end of the horizontal shaft 432 inserted into the pressure booster 411 has a limiting ring to prevent it from falling out.

[0040] A quick-switch toilet flushing system includes a quick-switch toilet flushing device and a housing 4 for mounting a valve assembly; the housing includes a limiting part for engaging the valve assembly, the limiting part causing the valve assembly to be raised and facing the water flow, and the raised valve assembly will leave enough space for retraction under force; wherein the limiting part is the aforementioned engaging structure for the limiting ring of the annular diaphragm 413.

[0041] Example 1

[0042] When the water tank is full, its float will rise, causing the swing arm 441 to swing and seal the second rubber pad 444 against the lower pressure relief hole 4201. In this way, the lower diaphragm valve rear chamber 420 is under positive pressure, which will block the connecting channel B and keep its lower flushing port 3 closed. At this time, the connecting component on the lower diaphragm valve 42 is pressing against the upper pressure boosting hole 4101. Under the action of water flow, the upper diaphragm valve 41 will retract to the upper diaphragm valve rear chamber 410, and the pressure in the upper diaphragm valve rear chamber 410 will be discharged from the upper pressure relief hole 4102. This will realize the connection of the connecting channel A and allow water to flush the upper flushing port 2.

[0043] Example 2

[0044] When the water level in the tank drops to a point where the buoyancy of the float is insufficient to hold the swing arm 441 against the lower pressure relief port 4201, the lower pressure relief port 4201 opens. The lower diaphragm valve 42, under the force of water, retracts to the lower diaphragm valve 42, thereby opening the connecting channel B to allow water to flush down the flush port 3. During this period, the connecting assembly loses its blockage of the upper pressure boosting port 4101 because the lower diaphragm valve 42 retracts to the lower diaphragm valve rear chamber 420. Since the diameter of the upper pressure boosting port 4101 is larger than that of the upper pressure relief port 4102, the water and air intake from the upper pressure boosting port 4101 into the upper diaphragm valve rear chamber 410 is greater than that from the upper pressure relief port 4102. Thus, the upper diaphragm valve rear chamber 410 is in a positive pressure state, and the connecting channel A is closed.
