Description

Technical Field

[0001] The utility model relates to the technical field of vacuum toilets, in particular to a non-electrically driven vacuum toilet system. Background Art

[0002] A vacuum toilet is a toilet that creates a vacuum in the entire toilet system. There is a flush valve on the passage leading to each toilet that isolates it from the system. When the toilet is flushed, this valve opens, relying on the pressure difference between the atmospheric pressure to clean the dirty water in the toilet.

[0003] A vacuum toilet is a system that creates a vacuum for the entire system. Each toilet in the system must be isolated from the system by an isolation valve. When flushing the toilet, this valve is opened to remove the contents of the toilet by relying on the pressure difference with atmospheric pressure. An ordinary toilet consumes 6 liters of water per flush, while a vacuum toilet only consumes 0.61 liters. The vacuum system is maintained by the automatic operation of a vacuum source. A vacuum toilet is generally maintained by a vacuum source and a controller that forms a pressure difference with atmospheric pressure to remove the contents of the toilet. At the same time, the controller controls the water inlet valve to open and flush the toilet. In existing vacuum toilet systems, each unit is relatively independent, with a large number of components and specifications, and most of the components are electrically driven.

[0048] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0049] Example:

[0050] like Figure 1 A non-electrically driven vacuum toilet system is shown, comprising a controller A, a trigger switch B, a water valve C and a vacuum valve D. The trigger switch is connected to the controller to control the opening and closing of the controller; the water valve is connected to the passage between tap water and the toilet, the vacuum valve is connected to the passage between the vacuum station and the toilet, and the two output ends of the controller are respectively connected to the water valve and the vacuum valve to control the opening and closing of the water valve and the vacuum valve respectively; when the water valve is opened, the toilet E starts to be cleaned and replenished with water; when the vacuum valve is opened, the dirty water in the toilet is pumped away.

[0051] In this embodiment, the output port of the trigger switch is connected to the first control terminal A1 of the controller; the controller includes a first output terminal A4 and a second output terminal A5, the first output terminal A4 is connected to the third control terminal D1 of the vacuum valve, and the second output terminal A5 is connected to the second control terminal C2 of the water valve; the water valve includes an inlet pipe C4 and an outlet pipe C5, the inlet pipe is connected to tap water, and the outlet pipe is connected to the toilet E; the inlet end D2 of the vacuum valve is connected to the toilet E, and its outlet end D3 is connected to the vacuum station.

[0052] The controller also includes a vacuum channel A2, which is connected to the vacuum station.

[0053] The vacuum valve is used to control the connection between the toilet and the vacuum station, and the water valve is used to control the flushing and water replenishment of the toilet.

[0054] Press the trigger switch B, and the output port B4 of the trigger switch will pass air to the first control terminal A1 of the controller A, and the controller A will be turned on. The first output terminal A4 and the second output terminal A5 of the controller will output vacuum negative pressure at the same time. When the first output terminal A4 and the second output terminal A5 are both at vacuum negative pressure, the water valve C and the vacuum valve D will be opened at the same time. Then, the vacuum valve will be opened, the dirty water in the toilet will be pumped away, the water valve will be opened, and the toilet will start to flush and replenish water.

[0055] The structures and operating principles of the controller A, trigger switch B, water valve C and vacuum valve D are described below:

[0056] like Figure 10-11 As shown, the trigger switch B includes a switch housing B1 and a trigger mechanism B2. The trigger mechanism is arranged in the switch housing. The trigger mechanism includes a button assembly and a first plug B3. The button assembly is installed in the switch housing and its lower end is deep in the switch housing. The first plug is arranged near the output port B4 of the switch housing. A magnetic attraction assembly is provided between the button assembly and the first plug. When the button assembly is forced to move toward the first 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 first plug away from the output port of the trigger switch and moving toward the button assembly.

[0057] Specifically, a connecting port B5 is provided inside and in the middle of the switch housing, which divides the interior of the switch housing into a first inner chamber b1 and a second inner chamber b2. The button assembly is arranged in the first inner chamber, and the first plug is arranged in the second inner chamber; the output port B4 of the trigger switch 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 first plug.

[0058] 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 switch housing. The button is movably mounted on the button mounting seat. The lower end of the button passes through the button mounting seat and extends into the switch housing. The lower end and middle part of the button has a tubular first mounting portion B61, and the first mounting portion of the button can move back and forth in the first inner chamber. Preferably, in this embodiment, the first magnetic suction component B9 is fixedly mounted on the first mounting portion.

[0059] 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 then penetrates into the switch housing.

[0060] The user manually presses the button, and the button moves downward to squeeze 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.

[0061] Preferably in this embodiment, the first magnetic attraction member is threadedly connected to the first mounting portion.

[0062] When the user manually presses the button and the button moves downward under the force, the top of the button presses the first spring downward, and the first 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 first 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 of the plug to move 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 first plug to move upward. The first 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 first plug instantly leaves the output port of the trigger switch.

[0063] In this embodiment, in order to prevent the button from detaching from the button mounting seat, a stopper B62 is provided outside the first mounting portion of the button, and the stopper is fixedly mounted on the side wall of the first 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 first mounting portion of the button.

[0064] Due to the limitation of the limiter and the connecting port, the tubular first mounting portion of the button can only move within the first inner chamber. When moving upward, the limiter and the button mounting seat abut against each other to prevent the button from moving further upward; when moving downward, the tubular first mounting portion and the connecting port abut against each other to prevent the button from moving further downward.

[0065] Specifically, the second inner chamber is provided with a second magnetic component B10 and a first plug B3. The second magnetic component is installed on the magnet seat B14. The lower end of the magnet seat is connected to the first 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), the first plug will be driven to move up instantly away from the output port of the trigger switch, and will stop when the first magnetic component and the second magnetic component are adsorbed.

[0066] The second inner chamber is also provided with a second spring B11 for driving the first plug to return to its original position. The second spring is provided between the connecting port and the second magnetic attraction component. When the first plug moves up away from the output port of the trigger switch, the second spring is squeezed. When the first 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 first plug to move downward back to the output port of the trigger switch.

[0067] Specifically, the output port of the trigger switch is connected to the first gas channel B12 and the second gas channel B13. When the first plug is pressed against the output port of the trigger switch, the first gas channel and the second gas channel are not connected; when the first plug leaves the output port of the trigger switch, the first gas channel and the second gas channel are connected.

[0068] In this embodiment, the first gas channel is an atmospheric channel. In actual use of this embodiment, the second gas channel is connected to a controller. In this embodiment, the controller is actually controlled by connecting the first gas channel and the second gas channel.

[0069] In this embodiment, the first plug is a rubber plug.

[0070] 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 magnets, and the magnetic poles of the two magnets that are close to each other are opposite.

[0071] The action process of triggering the switch is:

[0072] In the initial state, the first gas channel is connected to the air, and the second gas channel is connected to the controller. At this time, the button does not move downward, the first spring is not compressed, the first plug abuts against the output port of the trigger switch, and the second spring is not compressed;

[0073] 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 first 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 first 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. When the magnetic attraction force gradually increases to a certain extent (at a preset distance, the magnetic attraction force gradually increases to overcome the resistance of the plug moving up), the second magnetic member will drive the first plug to move up. The first plug moves up instantly under the action of the larger magnetic attraction force, and the second spring is compressed. The first plug stops moving up after the first magnetic member and the second magnetic member are attracted, and the first plug completely leaves the output port of the trigger switch. At this time, the first gas channel and the second gas channel are connected, and the second gas channel is connected to the air and transmitted to the downstream controller;

[0074] Since the first spring and the second spring are compressed to the maximum, they will respectively generate maximum rebound forces to act on the first magnetic component and the second magnetic component, 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 the button is not acted upon by external force, the rebound force of the first spring and the rebound force of the second spring will separate the button from the first plug.

[0075] In the vacuum toilet system, by pressing the button once, the first plug opens the output port and then closes the output port; by pressing the button for a long time, the first plug opens the output port and keeps the output port open. Specifically, in this embodiment, by pressing the button once, the first plug opens the output port, and the toilet is filled with water to start flushing; by pressing the button for a long time, the first plug opens the output port and keeps the output port open, and the toilet is constantly filled with water for flushing.

[0076] like Figure 2-Figure 9 As shown, the controller A includes a first control terminal A1, a vacuum channel A2, an air channel A3, a first output terminal A4, a second output terminal A5 and a switching component A7. The vacuum channel is connected to the vacuum station, and air is passed into the air channel. The first control terminal passes gases of different pressures to control the action of the switching component. When normal pressure air is passed into the first control terminal, the switching component is actuated to connect the first output terminal and the second output terminal of the controller to the vacuum channel. When the first control terminal is under vacuum negative pressure, the switching component is actuated to connect the first output terminal of the controller to the air channel.

[0077] Specifically, the controller also includes a first air cavity a1, a second air cavity a2, a third air cavity a3, a fourth air cavity a4, and a fifth air cavity a5. The first air cavity is connected to the first control end, the second air cavity is connected to the vacuum channel, the third air cavity is connected to the vacuum channel, the fourth air cavity is connected to the first output end of the controller, and the fifth cavity is connected to the second output end of the controller.

[0078] It should be noted that before the utility model is connected to the vacuum system, that is, the vacuum channel A2 is not connected to the vacuum station, at this time, the first air cavity a1 is at atmospheric pressure, the second air cavity a2 is at atmospheric pressure, the third air cavity a3 is at atmospheric pressure, the fourth air cavity a4 is at atmospheric pressure, and the fifth air cavity a5 is at atmospheric pressure. When the controller is connected to the vacuum system, the vacuum channel A2 is connected to the vacuum negative pressure, and a large amount of vacuum negative pressure quickly flows into the second air cavity a2, forming an air pressure difference with the first air cavity a1, and the switching component A7 moves downward from the air conduction position T2 to the vacuum conduction position T1, and the vacuum negative pressure The pressure gradually enters the fourth air cavity a4 and the fifth air cavity a5 from the vacuum channel A2 through the third air cavity a3, and the fourth air cavity and the fifth air cavity are transformed into a vacuum negative pressure state; in this process, the first air cavity a1 also gradually enters a vacuum negative pressure state, and when the air pressure between the first air cavity and the second air cavity is balanced, the switching component gradually moves from the vacuum conduction position T1 to the air conduction position T2, and when the first air cavity is completely converted to a vacuum negative pressure, the moving shaft stops moving; after the moving shaft stops moving, the controller is in a stable state after the first access to the vacuum system, and when the first control end is connected to the atmospheric pressure, the controller will start. In other words, when the controller is connected to the vacuum system, it will start once immediately. Compared with the existing controllers on the market, the utility model starts once more than the prior art products.

[0079] After the controller is connected to the vacuum system and started for the first time, it is in a stable state, that is, a normal state. The switching component does not operate. The first air cavity a1 is in a vacuum negative pressure state, the second air cavity a2 is in a vacuum negative pressure state, the third air cavity a3 is in a vacuum negative pressure state, the fourth air cavity a4 is in a normal pressure state, and the fifth air cavity a5 is in a normal pressure state. The first output end of the controller does not output vacuum negative pressure, and the second output end of the controller does not output vacuum negative pressure.

[0080] Specifically, a check valve A8 is provided between the fourth air cavity a4 and the fifth air cavity a5. When the fourth air cavity is connected to the vacuum channel, the check valve opens, and the fourth air cavity a4, the fifth air cavity a5, the first output end A4 of the controller, and the second output end A5 of the controller are all in a vacuum state; when the fourth air cavity is connected to the air channel, the check valve does not operate.

[0081] Specifically, the switching component A7 includes a diaphragm A71, a movable shaft A72 and a spring A73. The diaphragm is arranged between the first air cavity and the second air cavity, and the first air cavity and the second air cavity are not connected to each other. The spring is arranged in the second air cavity and connected to the diaphragm. The head end of the movable shaft is located in the second air cavity and connected to the diaphragm, and the end thereof passes through the third air cavity and is located in the fourth air cavity. The first air cavity and the second air cavity form an air pressure difference, which can drive the diaphragm to deform, so as to drive the movable shaft to move synchronously. The end of the movable shaft moves back and forth between the vacuum conduction position T1 between the vacuum channel and the fourth air cavity and the air conduction position T2 between the air channel and the fourth air cavity.

[0082] When air is introduced into the first control end (the first control end is turned on), the first air cavity is at normal pressure, and the second air cavity is at vacuum negative pressure. A pressure difference is formed between the first air cavity and the second air cavity. The diaphragm is squeezed by the gas in the first air cavity and deforms and displaces toward the second air cavity. At the same time, the movable shaft is driven to pass through the third air cavity and move toward the inside of the fourth air cavity. The end of the movable shaft gradually leaves the air conduction position T2 and moves toward the vacuum conduction position T1. The vacuum gradually enters the fourth air cavity from the vacuum channel A2 through the third air cavity. The fourth air cavity is transformed into a vacuum negative pressure state. During this process, the movable shaft compresses the spring to the maximum. On the contrary, when the first air cavity gradually restores the vacuum negative pressure, the diaphragm gradually restores its deformation under the reaction force of the spring, and at the same time drives the movable shaft to gradually move from the vacuum conduction position T1 to the air conduction position T2. ​​When the first air cavity is completely restored to the vacuum negative pressure, the movable shaft stops moving.

[0083] In order to maintain a certain amount of water in the toilet, the water valve is opened longer than the vacuum valve. After the vacuum valve is opened to pump out the dirty water in the toilet, the vacuum valve is closed and the water valve remains open to flush the toilet and replenish water.

[0084] In this embodiment, in order to ensure that the dirty water in the toilet is completely pumped out, a first delay mechanism A81 is provided on the passage connecting the first air cavity and the vacuum channel. The first delay mechanism is used to control the connection time between the vacuum channel and the fourth air cavity, thereby controlling the opening time of the vacuum valve.

[0085] In this embodiment, the second output end of the controller is connected to the atmosphere port A10. To ensure that a certain amount of water is maintained in the toilet after flushing, a second delay mechanism A82 is provided on the passage between the second output end of the controller and the atmosphere port. The second delay mechanism is used to control the opening time of the water valve.

[0086] like Figure 7-Figure 9 As shown, the delay mechanism A8, which has the same structure as the first delay mechanism and the second delay mechanism, includes a second plug A83 and a second valve port A84 with a circular cross-section (here, a cross-section perpendicular to the axial direction of the second plug or the second valve port), and the second valve port is arranged on the passage, and the second plug includes a flow limiting portion A831 and a second mounting portion A832, and the second mounting portion is mounted on the controller housing, and the flow limiting portion has an inclined surface A833. When the flow limiting portion of the second plug is screwed into the second valve port, a gap S1 for adjusting the gas flow is formed between the inclined surface and the second valve port.

[0087] Preferably, in this embodiment, the outer periphery of the second mounting portion has threads, and the second plug is mounted on the controller housing via the threads, and the size of the gap S1 between the flow limiting portion and the second valve port is adjusted by rotating the second plug.

[0088] In order to facilitate the accurate calculation of the size of the gas flow, since the amount of gas flow is determined by the size of the gap, the flow limiting part is designed to be cylindrical rather than conical (most of the existing technologies are designed to be conical), and the second valve port is designed to be a matching circular port, and a part of the flow limiting part is cut off to form an inclined surface. When the flow limiting part is located at the second valve port, as the flow limiting part of the second plug is at different depths of the second valve port, gaps of different sizes are formed between the inclined surface and the second valve port. In this way, the amount of water in the toilet can be accurately controlled.

[0089] In order to facilitate understanding of the advantages brought by the inclined surface design, the disadvantages of the conical second plug in the prior art are first introduced here. The conical second plug has different depths in the second valve port, and will form annular gaps of different sizes with the second valve port. In order to accurately calculate the flow rate, the calculation of the annular gap is somewhat cumbersome. In this embodiment, the flow limiting portion is designed to be a cylindrical shape consistent with the radius of the second valve port, and only a part is cut off to form the inclined surface. The part forming the inclined surface will form a gap at the second valve port as shown in the figure. Fig. 9The gap S1 shown in the figure uses the area ratio of the gap to the cross-section of the second valve port. At this time, it is much easier to calculate the flow rate, and it is easier to achieve precise control of the flow rate. Therefore, the designer accurately controls the size of the gap between the flow limiting portion of the second plug and the second valve port through calculation to control the air pressure change time in the first air cavity, thereby controlling the speed of the moving axis of the switching component moving back and forth, and further controlling the air pressure change time in the fourth air cavity.

[0090] Correspondingly, the second valve port of the first delay mechanism is arranged on the passage connecting the first air cavity and the vacuum channel, and the second plug of the first delay mechanism is threadedly installed in the controller housing, and its flow limiting part is located in the second valve port and a gap S1 for adjusting the gas flow is formed between the second valve port and the second valve port. Since the outer periphery of the second mounting part has threads, it is convenient to use the number of threads to adjust the depth of the second plug in the second valve port, that is, different numbers of threads correspond to different depths of the second plug in the second valve port, and different depths correspond to gaps of different sizes, so the gap between the flow limiting part and the second valve port can be controlled. The size of the gap determines the amount of gas flux per unit time. When the flow rate is constant, the larger the gap, the more gas flow passes through in the same time, and the faster the time for the gas to fill the first air cavity is; the smaller the gap, the less gas flow passes through in the same time, and the slower the time for the gas to fill the first air cavity is; and the speed of the air pressure change in the first air cavity affects the switching speed of the switching component, and then affects the air pressure change time of the fourth air cavity, thereby achieving the control of the opening time of the vacuum valve.

[0091] Similarly, the second valve port of the second delay mechanism 7 is arranged on the passage between the second output end of the controller and the atmosphere port. By calculating the gap between the second plug of the second delay mechanism and the second valve port and adjusting the depth of the second plug, the opening time of the water valve can be accurately controlled.

[0092] The vacuum valve and the water valve are opened at the same time, and the dirty water in the toilet is pumped out and the water is replenished and flushed at the same time. After the dirty water in the toilet is pumped out, the vacuum valve is closed. At this time, the water valve remains open, and the toilet continues to be replenished with water and a certain amount of water is maintained in the toilet.

[0093] In order to ensure the air tightness of the air cavity, sealing rings (A91, A92) are respectively provided at the end of the moving shaft and the air conduction position T2 and at the end of the moving shaft and the vacuum conduction position T1.

[0094] In this embodiment, preferably, the diaphragm is a planar rubber diaphragm.

[0095] The controller's action process is:

[0096] The controller will start once immediately after being connected to the vacuum system, and then it will be in a stable state, that is, the switching component will not operate;

[0097] When in a stable state, the switching component does not operate, the first air cavity and the second air cavity are both in a vacuum negative pressure state, the first output end of the controller does not output a vacuum negative pressure, and the second output end of the controller does not output a vacuum negative pressure; when the first control end is opened and a large amount of air is quickly filled, the first air cavity is converted to a normal pressure state, while the second air cavity is in a vacuum negative pressure state, the air pressure balance between the first air cavity and the second air cavity is broken to form an air pressure difference, the diaphragm of the switching component undergoes a deformation displacement toward the inside of the second air cavity, and drives the moving shaft to displace synchronously, the end of the moving shaft moves from the air conduction position T2 between the air channel and the fourth air cavity to the vacuum conduction position T1 between the vacuum channel and the fourth air cavity, the fourth air cavity is filled with a vacuum negative pressure, the first output end of the controller outputs a vacuum negative pressure, and at the same time, the check valve is opened under vacuum pressure, the fifth air cavity is also filled with a vacuum negative pressure, and the second output end of the controller outputs a vacuum negative pressure, thereby, the first control end realizes the simultaneous opening of the vacuum valve and the water valve;

[0098] At this time, the first delay mechanism controls the vacuum channel to continuously input a small amount of vacuum negative pressure into the first air cavity. The duration of the first delay mechanism determines the time for the moving axis to move from the vacuum conduction position T1 to the air conduction position T2, which is also the time for the vacuum negative pressure in the fourth air cavity to be converted to normal pressure, that is, the opening time of the vacuum valve;

[0099] When the fourth air cavity is at normal pressure, the check valve does not open, and the fifth air cavity is still at a vacuum negative pressure state. The second delay mechanism controls the atmosphere port to continuously supply air to the fifth air cavity. The duration of the second delay mechanism determines the time for the fifth air cavity to be converted from vacuum negative pressure to normal pressure, which is also the time for the vacuum negative pressure output at the second output end of the controller. Under the action of the second delay mechanism, the vacuum negative pressure output time of the second output end of the controller is longer than the vacuum negative pressure output time of the first output end of the controller, that is, the opening time of the water valve is longer than the opening time of the vacuum valve.

[0100] As long as the operator controls the gas flow inflow time of the first delay mechanism and the second delay mechanism, the operator can accurately control the time when the first output end and the second output end of the controller output the vacuum pressure, thereby controlling the opening time of the vacuum valve and the water valve.

[0101] The trigger switch is turned on, the second gas channel is connected to the air and air is introduced into the first control end of the downstream controller, the switching component inside the controller starts to act, the first output end of the controller outputs vacuum negative pressure to the vacuum valve, the vacuum valve opens to connect the toilet and the vacuum station, and the dirty water in the toilet is pumped out, and at the same time, the second output end of the controller outputs vacuum negative pressure to the water valve, the water valve opens, flushes the toilet and replenishes water; the first control end closes the air supply, under the action of the first delay mechanism, the vacuum valve slowly closes, and under the action of the second delay mechanism, the water valve lags behind the vacuum valve and slowly closes.

[0102] like Figure 12-13As shown, the water valve C includes a valve body C1, a first elastic diaphragm C3, a water inlet pipe C4 and a water outlet pipe C5, the first elastic diaphragm cover is arranged on the upper end of the valve body, and the water inlet pipe and the water outlet pipe are both arranged on the lower end of the valve body; a button C6 and a valve core C7 are arranged in the valve body, the valve core is movably installed on the valve body, the top of the button is fixedly connected to the middle part of the first elastic diaphragm, the button protrudes from the upper end of the valve body, the first elastic diaphragm is deformed to drive the button to move in the valve body, the button is provided with a permanent magnet C8, the permanent magnet moves up and down in the valve body with the button and can link the valve core to move accordingly, thereby controlling the cut-off and conduction between the water inlet pipe and the water outlet pipe; the valve body is also provided with a second control end C2 of the water valve, the second control end C2 is connected to the second output end A5 of the controller, and is used to drive the first elastic diaphragm to deform and restore the deformation.

[0103] The valve body is started, that is, vacuum negative pressure is applied to the second control end of the water valve, and an air pressure difference is formed between the outside and the inside of the valve body. The first elastic diaphragm is deformed toward the inside of the valve body and drives the button to move downward. Since a permanent magnet is provided on the button, as the button moves downward, the magnetic adsorption force of the permanent magnet on the valve core (in this embodiment, the valve core is an iron core or the outside of the valve core is wrapped with a layer of carbon steel that can be adsorbed by the permanent magnet) becomes greater and greater. When the magnetic adsorption force gradually increases to a certain extent (the magnetic adsorption force can overcome the resistance of the valve core to move upward), the valve core will be driven to move upward. The valve core moves upward instantly under the action of a larger magnetic adsorption force, and stops after being adsorbed by the permanent magnet across the valve core cavity.

[0104] Specifically, a flow channel structure is provided between the water inlet pipe C4 and the water outlet pipe C5, and the flow channel structure includes a second elastic diaphragm C9 and a water flow port C91 and a first valve port C92 provided on the second elastic diaphragm. A sealed transition chamber C11 is formed between the valve body and the second elastic diaphragm. The water flow port is provided between the transition chamber and the water inlet pipe, that is, the tap water in the water inlet pipe can freely enter the transition chamber. The first valve port is provided between the transition chamber and the water outlet pipe, that is, when the first valve port is opened, the tap water in the transition chamber can freely enter the water outlet pipe; the valve core can move away from or close to the first valve port under the linkage of the button; since the tap water can freely enter the transition chamber C11 from the water inlet pipe along the water flow port C91, when the first valve port C92 is connected, the tap water in the transition chamber flows from the first valve port into the water outlet pipe and then into the toilet.

[0105] Specifically, the specific structure of the valve core movably installed in the valve body is: the bottom center of the valve body is concave to form a valve core cavity C12 with a circular cross-section, the valve core is movably installed in the valve core cavity, and the valve core cavity is connected to the transition cavity.

[0106] In this embodiment, the diameter of the water flow port is smaller than the diameter of the first valve port.

[0107] Specifically, a third spring C13 is further provided in the valve core cavity. The third spring is provided at one end of the valve core away from the first valve port. When the valve core moves upward and away from the first valve port, the third spring is squeezed to make the first valve port conductive.

[0108] Specifically, a fourth spring C14 is further provided in the valve body. The fourth spring is sleeved on the outer periphery of the valve core cavity and is located below the button. When the button moves downward, the fourth spring is squeezed.

[0109] The second output terminal A5 of the controller outputs vacuum to the second control terminal C2 of the water valve, and a pressure difference is formed between the inside and outside of the valve body of the water valve. The first elastic diaphragm C3 is deformed toward the inside of the valve body, driving the button C6 to move downward with the permanent magnet, and at the same time squeezing the fourth spring C14. The valve core moves upward instantly under the magnetic adsorption force of the permanent magnet C8, and stops after being adsorbed by the permanent magnet across the valve core cavity. At this time, the water outlet pipe C4 is connected to the water inlet pipe C5, and tap water in the water outlet pipe flows out to the outside; the second control terminal C2 of the water valve stops evacuating (the second output terminal A5 of the controller does not output vacuum to the second control terminal C2 of the water valve), and under the joint action of the rebound force of the fourth spring C14 and the rebound force of the third spring C13, the button C6 is separated from the valve core C7, and the button resets and moves upward back to the initial position, the valve core moves downward to the first valve port position, the water outlet pipe is not connected to the water inlet pipe, and no water flows out of the water outlet pipe.

[0110] Specifically, the valve body C1 and the first elastic diaphragm C3 form a closed cavity, and the second control end C2 of the water valve is connected to the closed cavity; when the second control end of the water valve is evacuated, the closed cavity is in a vacuum negative pressure state, and the first elastic diaphragm is deformed inwardly, driving the button to squeeze the fourth spring downward; when the second control end of the water valve stops evacuating and is in a normal air pressure state, the closed cavity is in a normal air pressure state, and the first elastic diaphragm recovers its deformation outwardly, and under the combined action of the rebound force of the fourth spring and the deformation recovery force of the first elastic diaphragm, the button moves up and resets.

[0111] In this embodiment, preferably, the permanent magnet is installed at the lower end of the button through a magnet seat, and the permanent magnet is used to generate a magnetic adsorption force on the valve core to drive the valve core to move upward.

[0112] In some embodiments, the valve body includes an upper shell C111, the lower end of which is sealed and connected to a lower shell C122; a button, a permanent magnet, a second control end of the water valve, a first elastic diaphragm, a third spring, a valve core, a valve core cavity, and a fourth spring are all disposed in the upper shell; and a second elastic diaphragm, a water inlet pipe, and a water outlet pipe are all disposed in the lower shell.

[0113] The first elastic diaphragm cover is arranged at the upper end of the upper shell, and the first elastic diaphragm and the upper shell form a closed cavity, the button is arranged in the upper shell and the top thereof is fixedly connected to the middle part of the first elastic diaphragm, the permanent magnet is installed at the lower end of the button through the magnet seat, the bottom center of the upper shell is concave to form a valve core cavity, the fourth spring sleeve is arranged on the outer periphery of the valve core cavity, the valve core is arranged in the valve core cavity and is located outside the closed cavity, the third spring is arranged in the valve core cavity and is located at the end of the valve core away from the first valve port, that is, it is arranged between the valve core and the bottom of the valve core cavity;

[0114] The water inlet pipe and the water outlet pipe are arranged in the lower shell body, the second elastic diaphragm is arranged in the lower shell body, and forms a sealed transition chamber with the upper shell body, the transition chamber is connected with the valve core chamber, the valve core can move back and forth in the valve core chamber and the transition chamber, the second elastic diaphragm is provided with a water flow port and a first valve port, the water flow port is arranged between the transition chamber and the water inlet pipe, the first valve port is arranged between the transition chamber and the water outlet pipe, the tap water enters the transition chamber from the water inlet pipe through the water flow port, and when the first valve port is opened, the tap water in the transition chamber flows into the water outlet pipe through the first valve port.

[0115] The action process of the water valve is:

[0116] A vacuum is drawn or normal pressure is maintained at the second control end of the water valve to form a pressure difference between the inside and outside of the valve body or to release the pressure difference, thereby driving the button to move, and then driving the valve core to move, thereby opening or closing the first valve port, that is, the water inlet pipe and the water outlet pipe are connected or cut off, thereby realizing the on-off control of the water valve.

[0117] The first valve port conduction action process: the second output end of the controller evacuates the second control end of the water valve, and a pressure difference is formed between the inside and outside of the valve body. The first elastic diaphragm deforms toward the inside of the valve body, and the driving button moves the permanent magnet downward, while squeezing the fourth spring. The magnetic adsorption force of the permanent magnet on the valve core gradually increases during the downward movement. When the magnetic adsorption force increases to overcome the resistance of the valve core to move upward, the valve core moves upward instantly and stops after being adsorbed by the permanent magnet across the valve core cavity. At this time, the water outlet pipe is connected to the water inlet pipe, and tap water in the water outlet pipe flows into the toilet;

[0118] The first valve port closing action process: the second output end of the controller stops vacuuming the second control end of the water valve, and under the joint action of the rebound force of the fourth spring and the rebound force of the third spring, the button separates from the valve core, the button resets and moves back to the initial position, the valve core moves down to the first valve port position, there is no conduction between the water outlet pipe and the water inlet pipe, no water comes out of the water outlet pipe, the toilet is not flushed, and water is not replenished.

[0119] like Figure 1As shown, the vacuum valve D is a conventional vacuum valve, which has a third control end D1, a water inlet end D2 and a water outlet end D3. The third control end of the vacuum valve is connected to the first output end A4 of the controller, the water inlet end D2 is connected to the toilet E, and the water outlet end D3 is connected to the vacuum station; when the third control end applies vacuum negative pressure, the valve of the vacuum valve opens, the water inlet end and the water outlet end are connected, and the dirty water in the toilet can be pumped out; when normal pressure air is introduced into the third control end, the valve of the vacuum valve is closed, and the water inlet end and the water outlet end are not connected.

[0120] The action process of the utility model is:

[0121] The vacuum toilet system is turned on, and the user manually presses the trigger switch. The output port of the trigger switch passes air to the first control end of the controller, and the controller is turned on. The switching component inside the controller starts to act, and the first output end and the second output end of the controller simultaneously output vacuum negative pressure. When the first output end and the second output end of the controller are at vacuum negative pressure, the water valve and the vacuum valve are opened at the same time, so that the dirty water in the toilet is pumped away, and the toilet starts to flush and replenish water;

[0122] Since the first spring and the second spring of the trigger switch are compressed to the maximum, a maximum rebound force will be generated to act on the first magnetic member and the second magnetic member together, driving the first magnetic member and the second magnetic member to separate and return to the initial position under the action of the maximum rebound force, the trigger switch is closed, and the air supply to the controller is stopped. At this time, the first air cavity of the controller is filled with air, and the first delay mechanism of the controller controls the vacuum channel to continuously apply a small amount of vacuum negative pressure to the first air cavity, so as to control the time when the vacuum negative pressure is output from the first output end of the controller (that is, the time when the vacuum valve is opened); the second delay mechanism controls the atmosphere to continuously supply air to the fifth air cavity, so as to control the time when the vacuum negative pressure is output from the second output end of the controller (that is, the time when the water valve is opened); under the action of the second delay mechanism, the time when the controller controls the water valve to open is longer than the time when the vacuum valve is opened; after the vacuum valve and the water valve are closed in turn, the vacuum toilet system is closed.

[0123] It should be noted that in the vacuum toilet system of the present embodiment, by pressing the button of the trigger switch, the first plug opens the output port, and the toilet starts to flush; by long pressing the button of the trigger switch, the first plug opens the output port and keeps the output port open, and the toilet is constantly replenished with water for flushing.
