Description

Technical Field

[0001] The present invention relates to the technical field of toilet buttons, and particularly to a pneumatic control button for a vacuum toilet. Background Art

[0002] The interior of a toilet tank mainly consists of components such as a water inlet pipe, a water outlet pipe, a seepage pipe, a water plug (for water inlet and outlet), a float ball, a flushing knob, and a lever. These components work together to achieve the flushing function of the toilet. When a user presses the toilet control button, the button will lift the water plug through a connecting rod or a lever, causing the water in the tank to flow out through the water outlet pipe. As the water flows out, the water level in the tank gradually drops. When the water level drops to a certain extent, the water plug will fall due to gravity, blocking the water outlet and stopping the water discharge. At the same time, the float ball will drop as the water level drops. After the water plug falls, the float ball will gradually rise due to buoyancy, pulling up the inlet valve through a connecting rod or a lever to allow new water to enter the tank. As the water continuously enters, the water level in the tank gradually rises. When the water level rises to a certain height, the float ball will push the connecting rod or the lever to close the inlet valve and stop the water from entering.

[0003] The accuracy and rebound efficiency of existing toilet tank buttons are low, and they cannot rebound quickly and accurately through atmospheric pressure. Due to design defects, material aging, etc., the rebound mechanism of toilet tank buttons causes slow or stuck rebounds, which not only affects the user experience but may also cause continuous flushing or leakage problems. Sometimes, the button cannot return completely to its original position during the rebound process, resulting in the button always being in a semi-pressed state, which not only affects the aesthetics but may also prevent the water in the tank from being completely sealed, causing waste of water resources. The low rebound efficiency causes excessive pressure or wear on mechanical components such as connecting rods and levers under the button, thereby shortening their service life. Toilet tank buttons with low accuracy and rebound efficiency will significantly reduce the user experience, and the resulting continuous flushing or leakage phenomena will cause waste of water resources. Summary of the Invention

[0004] Technical Problem to be Solved

[0005] Aiming at the problem of low accuracy and efficiency of existing toilet control buttons, the present invention provides a pneumatic control button for a vacuum toilet.

[0006] Technical Solution

[0007] To achieve the purpose of high and precise rebound efficiency of the toilet control button, the present invention is realized through the following technical solutions: A pneumatic control button for a vacuum toilet, comprising a button housing and a button connecting rod movably installed inside the button housing. An installation hole is provided on the button connecting rod for connecting a button air plug. The bottom end of the button housing is threadedly connected with a button base. One end surface of the button air plug is fixedly connected to the inner wall of the air chamber of the button base. A button spring is placed inside the air chamber of the button base, and the button spring is used to restore the button connecting rod to its normal state. The button base is provided with a return air hole for restoring the air volume required for pressing the button connecting rod. An installation thread is provided outside the button housing, and a button fixing nut is threadedly connected to the outer surface of the installation thread.

[0008] Further, a button air outlet is opened inside the button base, and a button return air port is opened inside the button base.

[0009] Further, the button air outlet communicates with the air chamber of the button base, and the button return air port communicates with the air chamber of the button base.

[0010] Further, the button fixing nut is used to be fixed on a wall surface or a ceramic body.

[0011] Beneficial effects

[0012] The present invention has the following beneficial effects:

[0013] (1) For this pneumatic control button of the vacuum toilet, by compressing the button air plug through the button connecting rod, the compression and release of the gas form a strong air pulse. When the button connecting rod is released, the button spring pushes the button air plug backward, and the atmosphere enters the air chamber inside the button base from the button return air port to prepare for the next press. The strong air pulse can more effectively drive the sewage discharge system of the vacuum toilet, improving the sewage discharge efficiency. The pulsed sewage discharge method also helps to reduce the waste of water resources.

[0014] (2) For this pneumatic control button of the vacuum toilet, through the close cooperation between the button connecting rod and the button air plug, and the rapid backward pushing action of the button spring, the response speed of the button is very fast. When the button is pressed, the button connecting rod can quickly compress the button air plug and release the gas. When the button is released, the button spring can quickly push the button air plug backward and return to its original position. The highly sensitive button enables the user to easily control the start and stop of the vacuum toilet, improving the convenience of use. The sensitive response also helps to reduce the possibility of misoperation and improve the reliability and stability of the toilet.

[0015] (3) The pneumatic control button of this vacuum toilet is designed with a button spring. When pressing the button, the user needs to apply a certain force to compress the button air plug and release the gas. At the same time, the reverse pushing force of the button spring can also provide a certain feedback force to the user, making the pressing process more comfortable. A comfortable pressing force can reduce the fatigue of the user during use and improve the comfort of use. A reasonable pressing force also helps to protect the components of the toilet from being damaged by excessive extrusion.

[0016] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0024] Please refer to Figures 1-4, an embodiment of the present invention provides a technical solution: a pneumatic control button for a vacuum toilet, including a button housing 2 and a button link 1 movably installed inside the button housing 2. An installation hole is provided on the button link 1 for connecting a button air plug 3. The bottom end of the button housing 2 is threadedly connected to a button base 4. One end surface of the button air plug 3 is fixedly connected to the inner wall of the air chamber of the button base 4. A button spring 5 is placed in the air chamber of the button base 4. The button spring 5 is used to restore the button link 1 to its normal state. The button base 4 is provided with a return air hole for restoring the air volume required for pressing the button link 1. An installation thread 9 is provided outside the button housing 2. A button fixing nut 6 is threadedly connected to the outer surface of the installation thread 9. The tight fit between the button link 1 and the button air plug 3, as well as the rapid reverse pushing action of the button spring 5, make the response speed of the button very fast. When the button is pressed, the button link 1 can quickly compress the button air plug 3 and release gas. When the button is released, the button spring 5 can quickly reverse push the button air plug 3 and return to its original position. The highly sensitive button enables the user to easily control the start and stop of the vacuum toilet, improving the convenience of use. The sensitive response also helps to reduce the possibility of misoperation and improve the reliability and stability of the toilet.

[0025] A button air outlet 7 is opened inside the button base 4, and a button return air port 8 is opened inside the button base 4. The button air outlet 7 communicates with the air chamber of the button base 4, and the button return air port 8 communicates with the air chamber of the button base 4. The button link 1 compresses the button air plug 3, thereby pressing the gas inside the button base 4 out from the button air outlet 7. During this process, due to the compression and release of the gas, a relatively strong air pulse is formed. When the button link 1 is released, the button spring 5 reversely pushes the button air plug 3, and the atmosphere enters the air chamber inside the button base 4 from the button return air port 8 to prepare for the next press. The relatively strong air pulse can more effectively drive the sewage discharge system of the vacuum toilet, improving the sewage discharge efficiency. The pulsed sewage discharge method also helps to reduce water resource waste.

[0026] The button fixing nut 6 is used to be fixed on the wall surface or ceramic body. First, install the button air plug 3 on the button link 1, put the button link 1 into the button housing 2, and place a spring in the button base 4. Place the button link 1 with the button air plug 3 in the button base 4 with the spring. The button housing 2 is sleeved outside the button link 1 and threadedly connected to the button base 4, thus facilitating installation.

[0027] Workflow of the present invention: First, install the button air plug 3 on the button connecting rod 1, insert the button connecting rod 1 into the button housing 2, place a spring in the button base 4, put the button connecting rod 1 with the button air plug 3 into the button base 4 with the spring, and thread the button housing 2 onto the button connecting rod 1 and connect it to the button base 4. By tightening the thread, ensure a tight connection between the button housing 2 and the button base 4, which is not easy to loosen. Another significant advantage of threaded connection is its convenience in disassembly and assembly. Threaded connection has unified specifications and standards, which makes the connection between different components more standardized, facilitating interchangeability and universality. After being tightened, due to the friction between the threads, threaded connection has a certain self-locking property, which can prevent loosening caused by vibration or external forces. Threaded connection is applicable to the connection of various metal materials and plastic materials, so it can meet the connection requirements between button housings 2 and button bases 4 of different materials and sizes.

[0028] When installing the button housing 2, place the button housing 2 into the installation opening, then screw the button fixing nut 6 onto the button housing 2 through the installation thread 9, and finally insert the button hose onto the button air outlet 7. When pressing the button connecting rod 1, the button connecting rod 1 compresses the button air plug 3, thereby pressing the gas inside the button base 4 out of the button air outlet 7 to start the sewage discharge of the vacuum toilet. When releasing the button connecting rod 1, the button spring 5 pushes the button air plug 3 back, and the atmosphere enters the air chamber inside the button base 4 from the button air return port 8. At this time, the button spring 5 fully expands and the button connecting rod 1 returns to its original state waiting for the next use.

[0029] The button connecting rod 1 compresses the button air plug 3, thereby pressing the gas inside the button base 4 out of the button air outlet 7. During this process, due to the compression and release of the gas, a strong air pulse is formed. When releasing the button connecting rod 1, the button spring 5 pushes the button air plug 3 back, and the atmosphere enters the air chamber inside the button base 4 from the button air return port 8 to prepare for the next press. The strong air pulse can more effectively drive the sewage discharge system of the vacuum toilet, improving the sewage discharge efficiency. The pulsed sewage discharge method also helps to reduce water resource waste.

[0030] The tight fit between the button connecting rod 1 and the button air plug 3, as well as the quick reverse pushing action of the button spring 5, make the response speed of the button very fast. When pressing the button, the button connecting rod 1 can quickly compress the button air plug 3 and release the gas. When releasing the button, the button spring 5 can quickly push the button air plug 3 back and return to its original position. The highly sensitive button enables users to easily control the start and stop of the vacuum toilet, improving the convenience of use. The sensitive response also helps to reduce the possibility of misoperation, improving the reliability and stability of the toilet.

[0031] The design of the button spring 5 is such that when the button is pressed, the user needs to apply a certain amount of force to compress the button air plug 3 and release the gas. At the same time, the reaction force of the button spring 5 can also provide a certain amount of feedback force to the user, making the pressing process more comfortable. A comfortable pressing force can reduce the fatigue of the user during use and improve the comfort of use. A reasonable pressing force also helps to protect the components of the toilet from being damaged by excessive extrusion.
