Description

Technical Field

[0001] This utility model relates to a toilet flushing tank operating mechanism, specifically a concealed toilet flushing tank operating mechanism. Background Technology

[0002] Wall-hung toilets are suspended from the ground, saving space compared to traditional floor-mounted toilets and making bathroom cleaning easier. The water tanks of wall-hung toilets are typically embedded in the wall for concealed installation, allowing for more flexible use of limited bathroom space and thus gaining widespread popularity.

[0003] Existing built-in toilet tanks typically use mechanical mechanisms to connect the control switch and the flush valve. These mechanical connections often employ complex structures such as linkages or gears to transmit force. This results in a large installation space for the tank, numerous small parts, and a complex mechanical connection structure, making installation and maintenance difficult. Especially within the already confined space of the tank, technicians often need more time to adjust or debug, hindering its widespread adoption.

[0004] Traditional linkage or gear connections for power transmission often experience friction and wear during the transmission process, leading to reduced transmission efficiency and potential operational issues such as jamming or malfunction, resulting in an unsmooth driving experience. Furthermore, linkage or gear transmissions require significant force from the user, offering limited flexibility and a poor overall toilet user experience. Utility Model Content

[0010] The piston rod is equipped with an upper vent groove. One end of the guide tube connects to the upper vent groove, and the other end connects to the lower vent groove. Pressing the drive device pushes the piston rod to move and generate compressed gas. The compressed gas drives the sliding sleeve to extend through the air guide tube, pushing the airbag to inflate. The sliding sleeve then pushes the valve stem of the drain valve to open, thus flushing the toilet.

[0011] The inner end of the main cylinder protrudes to form a connecting pipe, and the upper vent groove passes through the connecting pipe; the air guide pipe is fitted onto the outside of the connecting pipe and connected to it.

[0012] The drive device also includes a drive button, which covers the end face of the piston rod and is embedded in the drive hole.

[0013] The piston rod is fitted with a spring on its outer ring. One end of the spring presses against the end face of the piston rod, and the other end presses against the main cylinder. The spring generates a thrust, pushing the piston rod outward and resetting the drive device.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings. A concealed toilet flushing tank operating mechanism includes a housing 1 and a water tank 2 embedded therein, a drive hole 11 is provided through the end face of the housing 1, and a drive device 3 is embedded in the drive hole 11;

[0022] The water tank 2 is equipped with an airbag device 4, and the drive device 3 is connected to the airbag device 4 through the air guide pipe 8.

[0023] The airbag device 4 includes an airbag cylinder 41 and a sliding sleeve 42 built into it. The top of the sliding sleeve 42 is connected to a drain valve. The airbag cylinder 41 is hollow to form a lower movable groove 46, and the sliding sleeve 42 is telescopically installed in the lower movable groove 46. The drive device 3 includes a main cylinder 31 and a piston rod 32 built into it. The main cylinder 31 is hollow to form an upper movable groove 36, and the piston rod 32 is telescopically installed in the upper movable groove 36.

[0024] The sliding sleeve 42 is equipped with a lower air inlet pipe 43. The bottom of the lower air inlet pipe 43 is provided with a lower air passage groove 45. The airbag 44 is fitted and clamped between the lower air inlet pipe 43 and the sliding sleeve 42, and is connected to the lower air inlet pipe 43.

[0025] The piston rod 32 is provided with an upper vent groove 34. One end of the conduit is connected to the upper vent groove 34, and the other end is connected to the lower vent groove 45. Pressing the drive device 3 pushes the piston rod 32 to move and generate compressed gas. The compressed gas drives the sliding sleeve 42 to extend through the air guide pipe 8, pushing the air bag 44 to inflate. The sliding sleeve 42 pushes the valve stem 5 of the drain valve to open, realizing toilet flushing.

[0026] The inner end of the main cylinder 31 protrudes to form a connecting pipe 9, and the upper vent groove 34 passes through the connecting pipe 9; the air guide pipe 8 is fitted onto the outside of the connecting pipe 9 and connected to it.

[0027] The drive device 3 also includes a drive button 33, which covers the end face of the piston rod 32 and is embedded in the drive hole 11.

[0028] A spring 35 is installed on the outer ring of the piston rod 32. One end of the spring 35 presses against the end face of the piston rod 32, and the other end presses against the main cylinder 31. The spring 35 generates a thrust, pushing the piston rod 32 outward, and the drive device 3 resets.

[0029] Working principle: In the drive mechanism of the toilet flush tank, the drive device and the airbag device are connected by an air guide pipe. The mechanical transmission between the drive device and the airbag device is converted into pneumatic transmission by the air guide pipe, which simplifies the structure of the entire operating mechanism, reduces the number of parts, and avoids the cumbersome mechanical transmission structure of traditional linkage or gear.

[0030] The drive unit includes a main cylinder and a piston rod built into it. An upper movable groove is formed in the hollow main cylinder, and the piston rod is telescopically installed in the upper movable groove. When the user presses the drive button, it pushes the piston rod downward along the upper movable groove, compressing the air inside the main cylinder. The compressed gas is conducted through the upper vent groove to the air guide tube and then to the airbag device.

[0031] The airbag device includes an airbag cylinder and a sliding sleeve built into it. A lower movable groove is formed inside the hollow airbag cylinder, and the sliding sleeve is telescopically installed in the lower movable groove. Compressed gas enters the lower air inlet pipe through the lower vent groove, causing the airbag to inflate and simultaneously pushing the sliding sleeve outward along the lower movable groove. The sliding sleeve presses against and pushes the valve stem of the drain valve, opening the drain valve and realizing the flushing operation. The airbag device design reduces the number of parts, reduces the space occupied inside the flushing tank, has a more compact structure, a larger water capacity, and is easier to install.

[0032] When the user finishes pressing the flush button, the gas inside the airbag is gradually released. The sliding sleeve automatically resets under the thrust of the retracting airbag, retracting inwards to return the airbag to its initial state and close the drain valve, ready for the next flush. The reset process of the sliding sleeve is smooth and reliable, requiring no manual intervention and improving the automation of the flushing process.

[0033] Simultaneously, the piston rod retracts inward under the action of the spring, resetting and awaiting the user's next press. The button design is simple and intuitive, making operation easy. Users only need to lightly press the drive button to start the flushing operation, facilitating operation for people of different physical abilities, increasing user comfort and convenience, and making operation easier and less strenuous.

[0034] Compared to traditional mechanical transmission, pneumatic drive allows for rapid and powerful opening of the drain valve, ensuring flushing operation and avoiding unnecessary delays or excessive movement. Simultaneously, pneumatic drive provides more precise control over the flushing process, with smooth gas compression and release enhancing the fluidity and reliability of the flushing operation.

[0035] Using pneumatic drive not only simplifies the traditional mechanical drive method, but also reduces wear and tear on parts during the pneumatic drive process, avoiding traditional wear and tear problems, and improving the service life and flushing efficiency of the flushing tank. Therefore, it can be widely promoted.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
