Description

Technical Field

[0001] The invention relates to the field of sanitary ware, and in particular to a starting mechanism of a drain valve. Background Art

[0002] Existing drain valves usually include a button, a pull-up piece and a valve core. When draining water, the button is pressed to drive the valve core to open the water outlet of the drain valve through the pull-up piece to drain water. However, when the valve core closes the water outlet, the water pressure of the water tank acts on the valve core. Therefore, when draining water, it is necessary to overcome the gravity of the valve core and the pressure of the water in the water tank acting on the valve core. Therefore, a large operating force is usually required to drive the valve core to move, which makes the operation of the existing starting structure more laborious. Summary of the invention

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] like Figures 1 to 7 As shown, a starting mechanism of a drain valve comprises:

[0037] The drainage body has a water outlet 1301 connected to the water tank drain port. Specifically, the drainage body includes a shell 6, a cover 2 installed above the shell 6, and a base 13 installed below the shell 6, and the side of the base 13 is connected to an overflow pipe 11;

[0038] A valve core is movably disposed in the drainage body and has a sealing portion for opening and closing the water outlet 1301. Specifically, the sealing portion includes a sealing disk 10 installed at the bottom of the valve core and a sealing gasket 9 fixedly installed on the sealing disk 10;

[0039] A lifting member 4, movably disposed in the drainage body, and having a driving part 402 that cooperates with the valve core in transmission;

[0040] The bladder 3 is arranged in the drainage body, and the bladder 3 can expand or contract. Specifically, the bladder 3 is made of soft material;

[0041] A power source, when the power source is turned on, the bladder 3 expands to drive the valve core to open the water outlet 1301 through the lifting member 4.

[0042] In this embodiment, the power source is a water source that supplies water to the bladder 3 .

[0043] In this embodiment, the water source comes from a water inlet mechanism of the toilet (not shown in the figure), and the water inlet mechanism includes a brush ring water channel (not shown in the figure) for supplying water to the brush ring water path, and the cleaning surface of the toilet is flushed through the brush ring water channel, wherein the brush ring water channel includes a diversion channel (not shown in the figure) connected to the bladder body 3. When the water inlet mechanism takes in water, the water in the brush ring water channel flows from the diversion channel into the bladder body 3 to expand the bladder body 3. The opening and closing of the power source controlled by the water inlet mechanism does not require the provision of an independent switch valve, and the structure is simple and cost-saving.

[0044] In this embodiment, when the bladder 3 contracts, the water in the bladder 3 flows from the water diversion channel to the brush ring water channel to flush the toilet cleaning surface, so that the water source can return to the original path to flush the toilet cleaning surface without affecting the flushing water volume of the brush ring water channel.

[0045] In other embodiments, the power source may be an air source for supplying air to the bladder 3 .

[0046] In this embodiment, when the power source is turned off, the valve core is reset under the action of gravity and drives the bag body 3 to shrink through the lifting member 4.

[0047] In this embodiment, a working chamber 602 is provided in the drainage body, and the bladder 3 is arranged in the working chamber 602 to prevent the bladder 3 from interfering with the movement of the valve core, so that the operation is stable.

[0048] In this embodiment, a connector 1 is fixedly connected to the top of the working chamber 602 , and the power source is connected to the capsule 3 through the connector 1 .

[0049] In this embodiment, the lifting member 4 is a swing rod swingably arranged in the drainage body, and the end of the lifting member 4 away from the driving part 402 is a transmission part 401 that cooperates with the sac body 3 in transmission, and the transmission part 401 is located below the sac body 3. Specifically, the bottom of the sac body 3 is connected to a piston 5 that moves under the expansion or contraction of the sac body 3, and the sac body 3 is abutted and cooperated with the transmission 401 through the piston 5.

[0050] In this embodiment, it also includes a float 12 movably arranged in the drainage body. When the float 12 floats up to a first position, it can limit the valve core. When the float 12 falls to a second position, it gives way to the valve core, so that after the valve core opens the water outlet 1301, the valve core is limited by the float 12, so that the valve core remains in the position of opening the water outlet 1301, thereby extending the drainage time and meeting the flushing water volume requirement.

[0051] In this embodiment, the float 12 has a limiting portion 1201, the valve core is provided with a valve stem 7, the sealing portion is arranged at the bottom of the valve stem 7, and the valve stem 7 is provided with a locking portion 702 which cooperates with the limiting portion 1201. Specifically, the upper end of the valve stem 7 is also provided with a socket 701 for the driving portion 402 to extend into, and the driving portion 402 abuts against the upper surface of the socket 701 to drive the valve core to move.

[0052] In this embodiment, a cavity 601 is provided in the drainage body, and the cavity 601 has a water inlet 603 connected to the toilet water tank. The float 12 is movably arranged in the cavity 601, and also includes an adjusting member 8 movably installed at the water inlet 603, and the size of the water inlet 603 is adjusted by the adjusting member 8. Specifically, the water inlet 603 is arranged on the bottom wall of the cavity 601, and the adjusting member 8 is an adjusting plate with adjusting teeth. The inner wall of the cavity 601 is correspondingly provided with tooth grooves, and the size of the water inlet 603 is adjusted by rotating the adjusting plate; by setting an independent cavity 601, the float 12 floats up or falls in the cavity 601 to prevent other components in the water tank from interfering with the movement of the float 12, and the operation is stable, and by setting the adjusting member 8 for adjusting the size of the water inlet 603, the water outlet speed of the cavity 601 is adjusted, and then the falling time of the float 12 is controlled, thereby controlling the drainage amount of the drainage body.

[0053] The specific working process of this embodiment is as follows:

[0054] like Figure 4 As shown: Under normal circumstances, when the water tank is full to a preset position, the float 12 in the drainage body floats up, and the valve core is sealed with the water outlet 1301 due to its own gravity and the pressure of the water in the water tank, thereby closing the water outlet 1301 to prevent the water in the water tank from flowing out of the water outlet 1301; at the same time, due to the action of the valve core, the transmission part 401 of the lifting rod supports the bladder 3, and the power source has not been opened at this time, and the bladder 3 shrinks naturally;

[0055] like Figure 5 As shown: when drainage is required, the water inlet mechanism is opened, and water flows into the bladder 3 from the water diversion channel through the joint 1, pushing the bladder 3 open to expand it, and the bladder 3 expands and presses the transmission part 401 of the lifting member 4 to move downward. At this time, the driving part 402 of the lifting member 4 moves upward and drives the valve core to move upward together, so that the sealing part of the valve core opens the water outlet 1301, and the water in the water tank flows out from the water outlet 1301 to the toilet pipeline; at the same time, because the float 12 still remains in a floating state, the locking part 702 of the valve core and the limiting part 1201 of the float 12 are in contact and limited cooperation, so that the valve core remains in a state of opening the water outlet 1301. At this time, even if the water supply to the bladder 3 is stopped, the valve core can still delay falling to achieve the purpose of extending the drainage time;

[0056] like Figure 6 As shown: as the water in the water tank is discharged, the water level drops, and the water in the compartment 601 is slowly discharged from the water inlet 603, and the float 12 slowly falls into an inclined state, so that the limit portion 1201 of the float 12 is separated from the clamping portion of the valve core;

[0057] like Figure 7As shown: when the water inlet mechanism stops supplying water to the bladder 3, the limiting part 1201 of the float 12 is completely separated from the locking part 702 of the valve core, the valve core will fall due to its own gravity, so that the sealing part and the water outlet 1301 are sealed again to prevent the water in the water tank from flowing out of the water outlet 1301; at the same time, the transmission part 401 of the lifting member 4 moves upward to push the bladder 3 upward, squeeze out the water in the bladder 3 to the brush ring water channel of the toilet, and restore the bladder 3 to the contracted state.

[0058] When drainage is completed and the valve core reseals the water outlet 1301, the water level in the water tank rises, and water enters the compartment 601 from the water inlet 603, thereby driving the float 12 to float again, so as to return to the initial water storage pre-drainage state and wait for the next cycle.

[0059] By setting an adjusting member 8 for adjusting the size of the water inlet 603, the water outlet speed of the compartment 601 is adjusted, thereby controlling the falling time of the float 12 and controlling the drainage volume of the drainage body.

[0060] This solution controls the opening and closing of the drain valve by the cooperation of the power source and the bladder 3. There is no need for manual pressing, and the operation is convenient and labor-saving. The opening and closing of the drain valve can be controlled by controlling the expansion or contraction of the bladder 3. The structure is simple and compact.

[0061] The above description shows and describes the preferred embodiments of the present invention. As mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention concept described herein through the above teachings or the technology or knowledge of the relevant field.
