Description

Technical Field

[0001] This utility model relates to the field of vacuum toilet technology, and further to an adjustable vacuum toilet. Background Technology

[0002] Due to the scarcity of freshwater resources on ships at sea, modern vessels use vacuum toilets to conserve freshwater. Furthermore, vacuum toilets effectively solve drainage problems caused by ship movement. When a ship is sailing on rough seas, the vacuum suction of a vacuum toilet can quickly remove waste, unaffected by the ship's tilt angle, thus providing a more comfortable experience for passengers.

[0003] With the development of the shipbuilding industry, more and more ships are equipped with vacuum toilets, which in turn leads to higher and higher requirements for vacuum toilets. For example, there is a need for precise adjustment of the water volume and air pumping time of the vacuum toilet to avoid excessive water consumption, which would result in waste of fresh water and excessive sewage discharge. However, most marine vacuum toilets on the market at present cannot precisely adjust the sewage discharge time and flushing water volume.

[0004] Therefore, it is necessary to design a vacuum toilet that allows for adjustment of the suction time and flushing water volume at any time to solve the above-mentioned technical problems. Utility Model Content

[0005] In view of the above-mentioned technical problems, the purpose of this utility model is to provide an adjustable vacuum toilet, which can solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides an adjustable vacuum toilet, comprising:

[0007] A vacuum controller, which is used to control the transmission of vacuum negative pressure;

[0008] A flushing water valve assembly is used to flush the toilet bowl. The flushing water valve assembly is connected to the vacuum controller so that the vacuum negative pressure can enter the flushing water valve assembly, thereby enabling the flushing water valve assembly to release high-pressure flushing water to flush the toilet bowl.

[0009] A drain valve assembly is used to drain waste from the toilet bowl. The drain valve assembly is connected to the vacuum controller so that the vacuum negative pressure can enter the drain valve assembly, thereby enabling the drain valve assembly to drain waste from the toilet bowl through vacuum suction.

[0010] Two flow control valves are respectively installed on the flushing water valve assembly and the drain valve assembly. The flow control valves are used to adjust the release amount of vacuum negative pressure in the flushing assembly or the drain valve assembly, so that the flushing water valve assembly and the drain valve assembly can respectively adjust the flushing water volume of the high-pressure flushing water and the duration of vacuum suction by controlling the flow control valves.

[0011] By setting a flow control valve, the system can autonomously control the amount of flushing water and the suction time during sewage discharge when the vacuum toilet is activated. It has the advantages of simple operation, long service life, and reliable quality, thus meeting the diverse needs of different users.

[0012] In some embodiments, the control valve includes a regulating valve body, the regulating valve body having a hollow interior forming a regulating cavity, a first valve core rotatably disposed within the regulating cavity, the first valve core having a flow channel formed thereon, so that the size of the flow channel can be adjusted by rotating the first valve core.

[0013] In some embodiments, the control valve further includes a drive device and a sensor. The drive device is used to control the first valve core. The drive device and the sensor are connected accordingly, and the sensor is disposed in the flushing water valve assembly or the drain valve assembly, so that the drive device can adjust the rotation degree of the first valve core according to the feedback information of the sensor, thereby adjusting the size of the flow channel.

[0014] By installing sensors in the flushing water valve assembly and the drain valve assembly respectively, and connecting the drive device to the first valve core, the water pressure and air pressure in the assembly can be monitored in real time. Then, the working state of the two control valves can be adjusted according to the monitoring results, thereby further realizing the intelligentization of the vacuum toilet in this application.

[0015] In some embodiments, the flushing water valve assembly includes a flushing valve body, which is connected to a first sealing air chamber, which is correspondingly connected to the vacuum controller. The flushing valve body has an inlet and an outlet, and the inlet and outlet are respectively connected to an inlet device and a flushing ring.

[0016] By setting a first sealing air chamber in the flushing valve body, the opening and closing of the flushing valve can be adjusted by controlling the air pressure change of the first sealing air chamber, thereby regulating the flow rate and duration of the flushing water, and also absorbing the water hammer effect generated during the flushing process, thus effectively reducing the impact on pipelines and valves.

[0017] In some embodiments, a first vacuum port is provided on the first sealed gas chamber, and the vacuum controller is connected to the first vacuum port through a one-way delivery pipe, wherein a check valve is provided in the one-way delivery pipe.

[0018] By setting a one-way connection between the vacuum controller and the first sealing chamber, the backflow of the medium between the vacuum controller and the first sealing chamber is effectively prevented, thereby effectively avoiding the backflow of sewage or gas into the vacuum controller, thus protecting the controller from contamination or damage. In addition, a one-way barrier is formed between the vacuum controller and the first sealing chamber, effectively ensuring that the negative pressure generated by the vacuum controller is not lost due to backflow, thus effectively ensuring the normal operation of the vacuum toilet.

[0019] In some embodiments, the drain valve assembly includes a drain valve body, which is connected to a second sealing chamber. The second sealing chamber is correspondingly connected to the vacuum controller. The drain valve body has an inlet and an outlet, which are respectively connected to the toilet flushing basin and an external sewage pipe.

[0020] By setting a second sealed air chamber, a sealed space can be formed inside the drain valve body when the drain valve assembly is closed, thereby ensuring that sufficient suction can be generated quickly during the next drain, thus effectively improving the working efficiency of the vacuum toilet. In addition, it can also effectively prevent sewage or odors from flowing back into the toilet bowl or vacuum pipe, thereby optimizing the level of hygiene and avoiding cross-contamination.

[0021] Compared with the prior art, the adjustable vacuum toilet provided by this utility model has the following beneficial effects:

[0022] 1. The adjustable vacuum toilet provided by this utility model, by setting a control valve, realizes the autonomous control of the flushing water volume and the suction time during sewage discharge when the vacuum toilet is started for flushing. It has the advantages of simple operation, long service life and reliable quality, and can meet the diverse needs of different users.

[0023] 2. The adjustable vacuum toilet provided by this utility model, by setting a vacuum controller and a first sealing chamber in a one-way connection, effectively prevents the backflow of the medium between the vacuum controller and the first sealing chamber, thereby effectively avoiding the backflow of sewage or gas into the vacuum controller, thus protecting the controller from contamination or damage. In addition, it also forms a one-way barrier between the vacuum controller and the first sealing chamber, effectively ensuring that the negative pressure generated by the vacuum controller is not lost due to backflow, thus effectively ensuring the normal operation of the vacuum toilet.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] In one embodiment, refer to the appendix to the specification. Figure 1 This utility model provides an adjustable vacuum toilet, comprising a vacuum controller 10, a flushing water valve assembly 30, a drain valve assembly 20, and a flow control valve 40. The vacuum controller 10 controls the transmission of negative vacuum pressure. The flushing water valve assembly 30 is used to flush the toilet bowl 50. The flushing water valve assembly 30 is connected to the vacuum controller 10 to allow negative vacuum pressure to enter the flushing water valve assembly 30, thereby releasing high-pressure flushing water to flush the toilet bowl 50. The drain valve assembly 20 is used to drain waste from the toilet bowl 50. The drain valve assembly 20 is connected to the vacuum controller 10 so that the vacuum negative pressure can enter the drain valve assembly 20, thereby enabling the drain valve assembly 20 to discharge sewage from the toilet bowl 50 through vacuum suction. Two control valves 40 are respectively installed on the flushing water valve assembly 30 and the drain valve assembly 20. The control valves 40 are used to adjust the release amount of vacuum negative pressure in the flushing assembly or the drain valve assembly 20, so that the flushing water valve assembly 30 and the drain valve assembly 20 can respectively adjust the flushing water volume of the high-pressure flushing water and the duration of vacuum suction by controlling the control valves 40.

[0034] Specifically, the adjustable vacuum toilet mainly includes a toilet body. The vacuum controller 10, flushing water valve assembly 30, drain valve assembly 20, and flow control valve 40 are all located on the back of the toilet body. The vacuum controller 10 includes a vacuum station, which is mainly used to output negative vacuum pressure. The vacuum controller 10 is connected to a pneumatic button via an air pipe, enabling the vacuum controller 10 to operate without electricity. This allows the vacuum controller 10 to be controlled by the button to turn on and off. The vacuum controller 10 has two vacuum output ports, each connected to the flushing... The flushing water valve assembly 30 and the drain valve assembly 20 are provided. The flushing water valve assembly 30 is located between the vacuum controller 10 and the toilet body. One end of the flushing water valve assembly 30 is connected to the water inlet device through a water pipe, and the other end is connected to the toilet bowl 50 through a water pipe, so that tap water can enter the toilet bowl 50 after passing through the flushing water valve assembly 30. The drain valve assembly 20 is located at the bottom of the toilet body. One end is connected to the bottom of the toilet bowl 50, and the other end is connected to the external drain pipe, so that the sewage in the toilet can be discharged to the drain pipe under the suction action of the drain valve assembly 20.

[0035] In one embodiment, based on the above embodiment, the control valve 40 includes a control valve body, the inside of which is hollow to form a control cavity, and a first valve core is rotatably disposed inside the control cavity. The first valve core has a flow channel, so that the size of the flow channel can be adjusted by rotating the first valve core.

[0036] Specifically, the first valve core is rotatably disposed in the regulating chamber. The flow channel on the first valve core is composed of holes, grooves or channels of a specific shape. Rotating the first valve core can change the size of the flow channel accordingly. The first valve core is connected to a knob 80 so that the user can manually rotate the knob 80 to control the volume control valve 40, thereby controlling the release amount of vacuum negative pressure in the flushing water valve assembly 30. In addition, the regulating valve body and the first valve core are sealed by a sealing ring to ensure the airtightness of the volume control valve 40. The first valve core is connected to the regulating chamber by a return spring so that the first valve core can return to the default position without external force.

[0037] It should be noted that the first valve core can also be telescopically disposed within the regulating chamber, thereby enabling it to move in and out relative to the regulating chamber to change the size of the flow channel.

[0038] In one embodiment, based on the above embodiment, the control valve 40 further includes a drive device and a sensor. The drive device is used to control the first valve core. The drive device and the sensor are connected accordingly, and the sensor is correspondingly disposed in the flushing water valve assembly 30 or the drain valve assembly 20, so that the drive device can adjust the rotation degree of the first valve core according to the feedback information of the sensor, thereby realizing the adjustment of the size of the flow channel.

[0039] Specifically, the drive device is connected to the first valve core through the valve stem, thereby enabling the first valve core to perform a predetermined movement under the drive of the drive device. The sensors in this invention are a water pressure sensor and a gas pressure sensor, which are respectively installed in the flushing water valve assembly 30 and the drain valve assembly 20 to monitor the water pressure and gas pressure in the assembly in real time. Based on the monitoring results, the working state of the two control valves 40 is adjusted, thereby further realizing the intelligentization of the vacuum toilet in this application.

[0040] In one embodiment, the flushing water valve assembly 30 includes a flushing valve body, which is connected to a first sealing air chamber. The first sealing air chamber is correspondingly connected to the vacuum controller 10. The flushing valve body has an inlet and an outlet, and the inlet and outlet are respectively connected to an inlet device and a flushing ring 70.

[0041] Specifically, by setting a first sealing air chamber in the flushing valve body, the opening and closing of the flushing valve can be adjusted by controlling the air pressure change of the first sealing air chamber, thereby regulating the flow rate and duration of the flushing water. Specifically, when the flushing valve assembly is open, the air pressure inside the first sealing air chamber changes, pushing the valve open and allowing water to flow through. When the flushing valve assembly is closed, the first sealing air chamber returns to negative pressure, pushing the valve closed and preventing water from flowing through. By setting the first sealing air chamber, the water hammer effect generated during the flushing process can also be absorbed, thereby effectively reducing the impact on the pipeline and valve.

[0042] In one embodiment, refer to the appendix to the specification. Figure 1 Based on the above embodiments, a first vacuum interface is provided on the first sealed gas chamber, and the vacuum controller 10 is connected to the first vacuum interface through a one-way delivery pipe, and a check valve 60 is provided in the one-way delivery pipe.

[0043] Specifically, by setting a check valve 60 between the vacuum controller 10 and the first sealing chamber, a one-way connection between the vacuum controller 10 and the first sealing chamber is achieved, effectively preventing the backflow of the medium between the vacuum controller 10 and the first sealing chamber. This effectively avoids the backflow of sewage or gas into the vacuum controller 10, thus protecting the controller from contamination or damage. In addition, it also forms a one-way barrier between the vacuum controller 10 and the first sealing chamber, effectively ensuring that the negative pressure generated by the vacuum controller 10 is not lost due to backflow, thereby effectively ensuring the normal operation of the vacuum toilet.

[0044] It should be noted that a one-way valve or a venturi tube can also be set in the one-way delivery pipe. The specific structure that can achieve one-way flow can be determined according to actual needs, and no limitation is made here.

[0045] In one embodiment, based on the above embodiment, the drain valve assembly 20 includes a drain valve body, which is connected to a second sealing air chamber. The second sealing air chamber is correspondingly connected to the vacuum controller 10. The drain valve body is provided with a drain inlet and a drain outlet, which are respectively connected to the toilet flushing basin and the external drain pipe.

[0046] Specifically, when the drain valve assembly 20 is closed, a negative pressure is formed inside the second sealing chamber, preventing outside air from entering the vacuum system; when the drain valve assembly 20 is opened, the negative pressure in the second sealing chamber is released, allowing sewage to be discharged quickly. By setting the second sealing chamber, a sealed space can be formed inside the drain valve body when the drain valve assembly 20 is closed, thereby ensuring that sufficient suction can be generated quickly during the next sewage discharge, thus effectively improving the working efficiency of the vacuum toilet. In addition, it can also effectively prevent sewage or odors from flowing back into the toilet bowl 50 or vacuum pipe, thereby optimizing the level of hygiene and avoiding cross-contamination.

[0047] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
