For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] The utility model provides a magnetic attraction trigger switch, which is applied to a vacuum toilet system and is used for controlling a water inlet valve and a vacuum valve controller, thereby starting the entire flushing system.

[0025] See also Figure 1-Figure 2As shown, a magnetic trigger switch includes a shell B1 and a trigger mechanism, wherein the trigger mechanism is arranged in the shell, and the trigger mechanism includes a button assembly and a plug B3, wherein the button assembly is installed at the upper end of the shell and its lower end is deeply inserted into the shell, and the plug is arranged near the output port B4 of the shell, and a magnetic attraction assembly is provided between the button assembly and the plug. When the button assembly is subjected to force to move toward the plug to a preset distance, the magnetic adsorption force generated by the magnetic attraction assembly can overcome the resistance of the plug when it moves up, thereby driving the plug to move away from the output port toward the button assembly.

[0026] Specifically, a connecting port B5 is provided in the middle of the shell, and the connecting port divides the interior of the shell into a first inner chamber b1 and a second inner chamber b2. The button assembly is arranged in the first inner chamber, and the plug is arranged in the second inner chamber; the output port is arranged at an end of the second inner chamber away from the connecting port; the magnetic attraction assembly includes a first magnetic attraction component B9 and a second magnetic attraction component B10, and the first magnetic attraction component and the second magnetic attraction component are respectively installed on the button assembly and the plug.

[0027] Specifically, the button assembly includes a button B6 and a button mounting seat B7, the button mounting seat is fixedly connected to the upper end of the shell, the button is movably mounted on the button mounting seat, the lower end of the button passes through the button mounting seat and extends deep into the shell, the lower end and middle part of the button has a tubular mounting portion B61, and the button mounting portion can move back and forth in the first inner chamber; in this embodiment, the first magnetic suction component B9 is fixedly mounted on the mounting portion.

[0028] The button assembly is also provided with a first spring B8 for driving the button to reset. The first spring is sleeved on the outer periphery of the lower end of the button. The first spring is located between the top of the button and the button mounting seat. The lower end of the button passes through the first spring and the button mounting seat in sequence and goes deep into the shell.

[0029] The button moves downward and squeezes the first spring and then stops moving. At this time, the first spring is compressed to the maximum, and the rebound force of the first spring compressed to the maximum drives the button to move upward and return to the initial state.

[0030] Preferably in this embodiment, the first magnetic attraction member is threadedly connected to the mounting portion.

[0031] When the user manually presses the button and the button moves downward under force, the top of the button presses the first spring downward, and the mounting portion of the button moves toward the connecting port and can only move within the first inner chamber. The first magnetic component moves downward with the mounting portion and passes through the connecting port. Due to the mutual attraction magnetic adsorption force generated between the first magnetic component and the second magnetic component, and as the first magnetic component moves downward, the magnetic adsorption force gradually increases. At a preset distance, when the magnetic adsorption force gradually increases to overcome the resistance to the plug moving upward (the resistance is the gravity of the second magnetic component, the magnet seat and the plug), the second magnetic component will be driven to drive the plug to move upward. The plug moves upward instantly under the action of the larger magnetic adsorption force, and stops moving upward after the first magnetic component and the second magnetic component are adsorbed, and the plug quickly leaves the output port.

[0032] In this embodiment, in order to prevent the button from detaching from the button mounting seat, a stopper B62 is provided outside the mounting portion of the button, and the stopper is fixedly mounted on the side wall of the mounting portion of the button. In this embodiment, preferably, the stopper is an annular retaining ring, and the retaining ring is sleeved on the outer peripheral wall of the mounting portion of the button.

[0033] Due to the limitation of the limiting member and the connecting port, the tubular mounting portion of the button can only move within the first inner chamber. When moving upward, the limiting member and the button mounting seat abut against each other to prevent the button from moving further upward; when moving downward, the tubular mounting portion and the connecting port abut against each other to prevent the button from moving further downward.

[0034] Specifically, the second inner chamber is provided with a second magnetic component B10 and the plug B3, the second magnetic component is installed on the magnet seat B14, and the lower end of the magnet seat is connected to the plug. When the first magnetic component gradually approaches the second magnetic component, a gradually increasing magnetic attraction force is generated. At a preset distance, when the magnetic attraction force gradually increases to overcome the resistance of the plug to move upward (the resistance is the gravity of the second magnetic component, the magnet seat and the plug), it will drive the plug to move up instantly away from the output port, and will stop when the first magnetic component and the second magnetic component are adsorbed.

[0035] The second inner chamber is also provided with a second spring B11 for driving the plug to return to its original position. The second spring is arranged between the connecting port and the second magnetic attraction component. When the plug moves up away from the output port, the second spring is squeezed. When the plug stops moving up, the second spring is compressed to the maximum. The rebound force of the second spring compressed to the maximum drives the plug to move downward back to the output port.

[0036] Specifically, the output port is connected to the first interface B12 and the second interface B13. When the plug is pressed against the output port, the first interface and the second interface are disconnected; when the plug is away from the output port, the first interface and the second interface are connected.

[0037] In this embodiment, the first interface is connected to the atmosphere. In actual use of this embodiment, the second interface is connected to a downstream device. In this embodiment, the downstream device is actually controlled by switching the first interface and the second interface.

[0038] In this embodiment, the plug is a rubber plug.

[0039] In this embodiment, the first magnetic attraction member is an iron column and the second magnetic attraction member is a magnet; conversely, it can be understood that the first magnetic attraction member is a magnet and the second magnetic attraction member is an iron column; in some embodiments, the first magnetic attraction member and the second magnetic attraction member are both permanent magnets, and the magnetic poles of the two permanent magnets that are close to each other are opposite.

[0040] The action process of the utility model is:

[0041] In the initial state, the first interface is connected to the air, and the second interface is connected to the downstream controller. At this time, the button does not move downward, the first spring is not compressed, the plug is against the output port, and the second spring is not compressed;

[0042] When the user applies external force to the button, the button begins to move downward under the force, and the top of the button presses the first spring downward. The mounting portion of the button moves toward the connecting port and can only move in the first inner chamber. The first magnetic member moves downward with the mounting portion and passes through the connecting port. Since the first magnetic member and the second magnetic member generate a magnetic attraction force that attracts each other, and as the first magnetic member moves downward, the magnetic attraction force gradually increases. At a preset distance, when the magnetic attraction force gradually increases to overcome the resistance to the plug moving upward (the resistance is the gravity of the second magnetic member, the magnet seat and the plug), the second magnetic member will be driven to drive the plug to move upward. The plug moves upward instantly under the action of the larger magnetic attraction force, and the second spring is compressed by the plug. The plug stops moving upward after the first magnetic member and the second magnetic member are attracted, and the plug completely leaves the output port. At this time, the first interface and the second interface are connected, and the second interface is connected to the air.

[0043] Since the first spring and the second spring are compressed to the maximum, they will generate maximum rebound forces to act on the first magnetic component and the second magnetic component respectively, driving the first magnetic component and the second magnetic component to separate and return to the initial position under the action of the maximum rebound force; that is, when there is no external force on the button, the rebound force of the first spring and the rebound force of the second spring will separate the button from the plug.

[0044] It is worth mentioning that by pressing the button once, the plug opens the output port and then closes the output port; by long pressing the button, the plug opens the output port and keeps the output port open.

[0045] It should be emphasized that the above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
