[0033] In one embodiment, the reference specification Figure 1The present invention provides an adjustable vacuum toilet, comprising a vacuum controller 10, a flushing water valve assembly 30, a sewage valve assembly 20 and a control valve 40, wherein the vacuum controller 10 is used to control the transmission of vacuum negative pressure, the flushing water valve assembly 30 is used to flush the toilet stool 50, the flushing water valve assembly 30 is connected to the vacuum controller 10 correspondingly so that the vacuum negative pressure can enter the flushing water valve assembly 30, and then the flushing water valve assembly 30 releases high-pressure flushing water to flush the toilet stool 50, the sewage valve assembly 20 is used to discharge sewage from the toilet stool 50, and the sewage discharge The valve assembly 20 is correspondingly connected to the vacuum controller 10 so that the vacuum negative pressure can enter the drain valve assembly 20, thereby realizing that the drain valve assembly 20 can discharge the toilet stool 50 through vacuum suction. The two quantity control regulating valves 40 are respectively arranged on the flushing water valve assembly 30 and the drain valve assembly 20. The quantity control regulating valve 40 is used to adjust the release amount of the 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 quantity control regulating valve 40.

[0034] Specifically, the adjustable vacuum toilet mainly includes a toilet body, and the vacuum controller 10, the flushing water valve assembly 30, the drain valve assembly 20 and the quantity control regulating valve 40 are all arranged on the back of the toilet body, wherein the vacuum controller 10 includes a vacuum station, and the vacuum station is mainly used to output vacuum negative pressure. In addition, the vacuum controller 10 is connected to the pneumatic button through an air pipe, so that the vacuum controller 10 can be driven without electricity, and the opening and closing of the vacuum controller 10 can be controlled by the operation button. The vacuum controller 10 has two vacuum output ports, and the two vacuum output ports are respectively connected to the flushing The water valve assembly 30 and the sewage valve assembly 20, the flushing water valve assembly 30 is arranged between the vacuum controller 10 and the toilet body, and 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 stool tank 50 of the toilet through a water pipe, so that tap water can enter the toilet stool tank 50 after passing through the flushing water valve assembly 30, and the sewage valve assembly 20 is arranged at the bottom of the toilet body, one end is connected to the bottom of the toilet stool tank 50, and the other end is connected to the external sewage pipeline, so that the sewage in the toilet can be discharged to the sewage pipeline under the suction action of the sewage valve assembly 20.

[0035] In one embodiment, based on the above embodiment, the quantity control regulating valve 40 includes a regulating valve body, the interior of the regulating valve body is hollow to form a regulating cavity, a first valve core is rotatably arranged in the regulating cavity, and a flow channel is opened on the first valve core 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 arranged in the regulating cavity, and the flow channel on the first valve core is composed of holes, grooves or channels of specific shapes. When the first valve core is rotated, the size of the flow channel can be changed accordingly. The first valve core is connected with a knob 80, so that the user can control the quantity control regulating valve 40 by manually turning the knob 80, thereby controlling the release amount of the 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 air tightness of the quantity control regulating valve 40. The first valve core is connected to the regulating cavity through a reset spring to achieve the first valve core can return to the default position in the absence of external force.

[0037] It should be pointed out that the first valve core can also be telescopically arranged in the regulating cavity, so as to be able to move in and out relative to the regulating cavity to change the size of the flow channel.

[0038] In one embodiment, based on the above embodiment, the quantity control regulating valve 40 also includes a driving device and a sensor, the driving device is used to control the first valve core, the driving device and the sensor are correspondingly connected, and the sensor is correspondingly arranged in the flushing water valve assembly 30 or the sewage valve assembly 20, so that the driving 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.

[0039] Specifically, the driving device is connected to the first valve core through the valve stem, so that the first valve core can perform a predetermined movement under the drive of the driving device. The sensors in the present invention are a water pressure sensor and an air pressure sensor, which are respectively installed in the flushing water valve assembly 30 and the sewage valve assembly 20 to monitor the water pressure and air pressure in the assembly in real time, respectively, and then adjust the working status of the two control valves 40 according to the monitoring results, thereby further realizing the intelligence 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 sealed air chamber. The first sealed air chamber is correspondingly connected to the vacuum controller 10. A water inlet and a water outlet are opened on the flushing valve body. The water inlet and the water outlet are respectively connected to a water inlet device and a flushing ring 70.

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

[0043] Specifically, by setting a check valve 60 between the vacuum controller 10 and the first sealed chamber, a one-way connection between the vacuum controller 10 and the first sealed chamber is achieved, which effectively prevents the backflow of the medium between the vacuum controller 10 and the first sealed chamber, thereby effectively avoiding the backflow of sewage or gas into the vacuum controller 10, thereby protecting the controller from contamination or damage. In addition, a one-way barrier is formed between the vacuum controller 10 and the first sealed chamber, effectively ensuring that the negative pressure generated by the vacuum controller 10 will not be lost due to backflow, thereby effectively ensuring the normal operation of the vacuum toilet.

[0044] It should be pointed out that the one-way delivery pipe can also be set as a one-way valve or a Venturi tube. The specific structure that can achieve one-way flow can be determined according to actual needs and is not limited here.

[0045] In one embodiment, based on the above embodiment, the sewage valve assembly 20 includes a sewage valve body, which is connected to a second sealed air chamber, and the second sealed air chamber is correspondingly connected to the vacuum controller 10. A sewage inlet and a sewage outlet are provided on the sewage valve body, and the sewage inlet and the sewage outlet are respectively connected to the toilet flushing bowl and the external sewage pipeline.

[0046] Specifically, when the drain valve assembly 20 is closed, negative pressure is formed inside the second sealed air chamber to prevent external air from entering the vacuum system; when the drain valve assembly 20 is opened, the second sealed air chamber releases the negative pressure to allow sewage to be discharged quickly. By setting up the second sealed air 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 quickly generated during the next sewage discharge, thereby effectively improving the working efficiency of the vacuum toilet. In addition, it can also effectively prevent sewage or odor from flowing back into the toilet stool 50 or the vacuum pipe, thereby achieving the purpose of optimizing the hygiene level and avoiding cross contamination.

[0047] The specific working principle of the present invention is as follows: after pressing the button 80, the start signal is transmitted to the vacuum controller 10, and the vacuum controller 10 is turned on to send the vacuum negative pressure into the first sealed air chamber of the sewage valve assembly 20 and the second sealed air chamber of the flushing water valve assembly 30. After the flushing water valve assembly 30 is connected to the vacuum negative pressure of the vacuum controller 10, the flushing valve body is opened, and the flushing water enters the flushing ring 70 through the flushing valve body to flush the toilet stool 50. During the flushing process, the vacuum negative pressure in the first sealed air chamber is regulated by the control valve 40 to control the release degree and thus control the flushing force. After the flushing is completed, the second sealed air chamber returns to the closed state. After the sewage valve assembly 20 is connected to the vacuum negative pressure of the vacuum controller 10, the second sealed air chamber forms a negative pressure environment. After opening the sewage valve assembly 20, the sewage in the toilet stool 50 is sucked and then discharged. Subsequently, under the control of the control valve 40, the vacuum negative pressure in the second sealed air chamber is gradually released, thereby achieving the effect of regulating the suction force.

[0048] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
