Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vacuum sewage discharge, in particular to a vacuum suction device, a vacuum toilet and a building cabin. BACKGROUND

[0002] In order to work or live in high-altitude areas, an insulation cabin is usually set up to provide an environment for work or life. The existing insulation cabin needs to be installed in an area above an altitude of 4000 meters. In the case of no pressure increase, the atmospheric pressure outside is only 0.5-0.6 of sea level. The temperature in the high-altitude area is relatively low, and it is easy to cause pipe freezing and other adverse conditions. In addition, the insulation cabin on the plateau is also prone to power failure, freezing, alternating cold and hot and other adverse conditions. These conditions will affect the normal use of various functional structures provided in the insulation cabin, such as the normal use of the vacuum toilet, and cannot meet the current use requirements for the plateau environment. SUMMARY

[0003] Therefore, the purpose of the embodiments of the present application is to provide a vacuum suction device, a vacuum toilet and a building cabin to improve the problem that the vacuum toilet in the existing insulation cabin cannot be used normally.

[0004] In order to solve the above problems, in a first aspect, the embodiments of the present application provide a vacuum suction device, which comprises a controller, a first vacuum pump, a second vacuum pump and a vacuum tank assembly. The controller is connected to the first vacuum pump and the second vacuum pump. The controller is used to determine a vacuum pump switching mode according to acquired temperature information, and control the first vacuum pump or the second vacuum pump to work based on the vacuum pump switching mode. The vacuum tank assembly is connected to the first vacuum pump and the second vacuum pump. The first vacuum pump and the second vacuum pump are used to control the vacuum degree of the vacuum tank assembly. The vacuum tank assembly is used to perform vacuum suction treatment on the connected water-using device based on the vacuum degree.

[0005] In the implementation process, two independent vacuum pumps are arranged in the vacuum suction device, and a controller connected with the two vacuum pumps determines a vacuum pump switching mode suitable for the current temperature environment according to the acquired temperature information, so as to control the first vacuum pump or the second vacuum pump to work in the determined vacuum pump switching mode. The vacuum pump is connected with a vacuum tank assembly, and when the first vacuum pump or the second vacuum pump works, the vacuum degree of the vacuum tank assembly can be controlled, so that the vacuum tank assembly can perform vacuum suction treatment on the externally connected water-using device based on the change of the vacuum degree. By switching the working of the two vacuum pumps according to the actual temperature condition by the controller, the damage caused by long-term high-frequency work of the vacuum pump is effectively reduced, thereby improving the service life of the vacuum suction device, and in the case that one of the vacuum pumps is abnormally affected by the environment, the vacuum suction device can still provide normal vacuum suction function for the externally connected water-using device, meeting the suction and cleaning requirements in various scenes.

[0006] Optionally, the first vacuum pump is a freeze-proof vacuum pump provided with a freeze-proof assembly. The freeze-proof assembly includes a clamp and a braided elastic pipeline.

[0007] In the implementation process, in order to cope with the low temperature condition in the plateau and other application scenarios, considering the adverse effects of low temperature condition on the pipeline, the first vacuum pump can be a freeze-proof vacuum pump provided with a freeze-proof assembly, so as to absorb the ice expansion space in the low-temperature icing condition through the freeze-proof assembly such as the clamp and the braided elastic pipeline, thereby reducing the damage of the first vacuum pump in the low-temperature condition, prolonging the service life of the first vacuum pump, and being suitable for various low-temperature application scenarios.

[0008] Optionally, the controller is specifically used for: preprocessing the temperature information to obtain temperature data; if it is determined that the temperature data is lower than or equal to a preset low-temperature threshold, the vacuum pump switching mode determined by the controller is a low-temperature switching mode; if it is determined that the temperature data is greater than or equal to a preset normal-temperature threshold, the vacuum pump switching mode determined by the controller is a normal-temperature switching mode.

[0009] In the implementation process, considering the change of the initial temperature information and the like, the controller can first preprocess the temperature information to obtain temperature data with higher effectiveness, and then determine a suitable vacuum pump switching mode based on the temperature data. In a case where the temperature data is lower than or equal to a preset low-temperature threshold, it is indicated that a low-temperature condition occurs, and a low-temperature switching mode can be enabled to switch and control the working states of the two vacuum pumps. In a case where the temperature data is greater than or equal to a preset normal-temperature threshold, it is indicated that the temperature is a normal temperature, and a normal-temperature switching mode can be enabled to switch and control the working states of the two vacuum pumps. Different vacuum pump switching modes can be determined according to the actual temperature condition to switch and control the two vacuum pumps, so as to prolong the service life of the two vacuum pumps and ensure the normal function of the vacuum pumping device in an abnormal condition by switching the working modes of the vacuum pumps.

[0010] Optionally, the low-temperature switching mode comprises that a first working time ratio of the first vacuum pump to the second vacuum pump is n:1, n is a positive integer greater than or equal to 2 and less than or equal to 5. The controller is specifically configured to control the second vacuum pump to work once after the first vacuum pump works n times based on the low-temperature switching mode.

[0011] In the implementation process, in a case of the low-temperature switching mode, since the first vacuum pump is a freeze-proof vacuum pump, the first working time ratio between the first vacuum pump and the second vacuum pump can be set to n:1. In the low-temperature switching mode, the first vacuum pump is controlled to work n times, and then the second vacuum pump is controlled to work once, and the cycle is repeated. In this way, the first vacuum pump can adapt to the low-temperature use environment by a high working frequency, and the working load of the first vacuum pump can be reduced by switching the use of the second vacuum pump, so as to provide effective vacuum pump function in a low-temperature condition and prolong the service life of the two vacuum pumps.

[0012] Optionally, the normal-temperature switching mode comprises that a first working time ratio of the first vacuum pump to the second vacuum pump is 1:m, m is a positive integer greater than or equal to 2 and less than or equal to 5. The controller is specifically configured to control the first vacuum pump to work once after the second vacuum pump works m times based on the normal-temperature switching mode.

[0013] In the implementation process described above, in the case of normal temperature switching mode, the second vacuum pump can be set as a vacuum pump with high power and high durability, so that the first working time ratio between the first vacuum pump and the second vacuum pump can be set as 1:m. In the normal temperature switching mode, the second vacuum pump is controlled to work m times, and then the first vacuum pump is controlled to work once, and the cycle is repeated. The high working frequency of the second vacuum pump can meet the use demand in the normal temperature environment, and the switching use of the first vacuum pump reduces the working load of the second vacuum pump due to over frequency, so as to provide effective vacuum pump function in the normal temperature condition and prolong the service life of the two vacuum pumps.

[0014] Optionally, the vacuum tank assembly comprises a first vacuum tank and a second vacuum tank. The first vacuum tank is connected to the first vacuum pump and the second vacuum pump, and the first vacuum tank is connected to the first part of the water-using devices. The second vacuum tank is connected to the first vacuum pump and the second vacuum pump, and the second vacuum tank is connected to the second part of the water-using devices. The first vacuum tank is used for vacuum suction treatment of the first part of the water-using devices based on the first vacuum degree controlled by the first vacuum pump or the second vacuum pump. The second vacuum tank is used for vacuum suction treatment of the second part of the water-using devices based on the second vacuum degree controlled by the first vacuum pump or the second vacuum pump.

[0015] In the implementation process described above, considering the low difference between internal and external air pressure in plateau area and the actual setting of external connection of multiple water-using devices, two vacuum tanks can be provided in the vacuum tank assembly, and the two vacuum tanks are respectively connected to the corresponding two vacuum pumps. The first vacuum tank is connected to the first part of the water-using devices outside, and the second vacuum tank is connected to the second part of the water-using devices outside, so as to control the vacuum degree of different vacuum tanks by the currently working vacuum pump, thereby providing vacuum suction treatment function for different parts of the water-using devices, to meet the water suction cleaning demand of different water-using devices.

[0016] Optionally, the first vacuum tank is connected to the second vacuum tank through a connecting pipeline. In the case that the drainage speed of the first vacuum tank does not meet the preset condition, the second vacuum tank is also used for providing gas to the first vacuum tank through the connecting pipeline. In the case that the drainage speed of the first vacuum tank does not meet the preset condition, the second vacuum tank is also used for providing gas to the first vacuum tank through the connecting pipeline.

[0017] In the implementation process, in order to provide more pressure in the plateau environment, considering the difference in use of the two vacuum tanks, the first vacuum tank and the second vacuum tank can be connected through the connecting pipeline. In the case that the drainage speed of the second vacuum tank does not meet the preset condition, that is, the drainage speed is low, the first vacuum tank can provide gas for the second vacuum tank based on the connecting pipeline to improve the drainage speed of the second vacuum tank. Correspondingly, in the case that the drainage speed of the first vacuum tank does not meet the preset condition, that is, the drainage speed is low, the second vacuum tank can provide gas for the first vacuum tank based on the connecting pipeline to improve the drainage speed of the first vacuum tank. When the drainage speed of a vacuum tank is low, the other vacuum tank can help with drainage, effectively improving the drainage speed when the vacuum tank is used, and further improving the efficiency of vacuum suction processing under the condition of providing sufficient suction pressure.

[0018] Optionally, the vacuum tank assembly further comprises a first one-way valve and a second one-way valve. The first one-way valve is connected with the first vacuum tank, and the first one-way valve is used for one-way output of the wastewater discharged by the first vacuum tank. The second one-way valve is connected with the second vacuum tank, and the second one-way valve is used for one-way output of the wastewater discharged by the second vacuum tank.

[0019] In the implementation process, in order to process the wastewater discharged by the two vacuum tanks, a corresponding one-way valve can be connected behind each of the two vacuum tanks to one-way output the wastewater discharged by the two vacuum tanks to the outside for corresponding wastewater treatment through the one-way valve. The limitation of the one-way valve can reduce the adverse situation of wastewater flowing back to the vacuum tank.

[0020] In a second aspect, the embodiments of the present application also provide a vacuum toilet, comprising a water using device and the vacuum suction device according to any one of the preceding embodiments. The water using device is connected with the vacuum suction device. The water using device is provided with a water pumping switch, and the vacuum suction device is used for vacuum suction processing of the connected water using device according to feedback information of the water pumping switch.

[0021] In the implementation process, the water using device is provided with a corresponding water pumping switch, so that the vacuum suction device connected therewith is controlled to perform vacuum suction processing on the water using device according to feedback information of the water pumping switch. The vacuum suction technology is used to process wastewater and dirt, effectively reducing the water resources required for cleaning the water using device and reducing the discharge amount of wastewater, and is suitable for various application environments such as plateau and mobile carrier.

[0022] In a third aspect, the embodiments of the present application further provide a building cabin, comprising the vacuum suction device according to any one of the above or the vacuum toilet according to the above.

[0023] To sum up, the embodiments of the present application provide a vacuum suction device, a vacuum toilet and a building cabin, which can switch the working of two vacuum pumps according to the actual temperature condition, effectively reducing the damage caused by long-term high-frequency working of the vacuum pump, thereby prolonging the service life of the vacuum suction device, optimizing the use effect of the vacuum toilet and meeting the use requirements of the building cabin.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0028] The existing thermal cabin needs to be installed in an area above 4000 meters above sea level. In the case of no supercharging, the external atmospheric pressure is only 0.5-0.6 of sea level. The temperature in the high-altitude area is low, and it is easy to cause freezing and other adverse conditions. Moreover, the thermal cabin on the plateau is also prone to power failure, freezing, alternating cold and hot, and other adverse conditions, which will affect the various functional structures arranged in the thermal cabin, for example, the freezing of the pipeline of the vacuum toilet in the low-temperature condition, and because of the use in the plateau environment, the external atmospheric pressure is low, the vacuum pressure difference is small, and more time is needed to achieve the same effect as the use on the plain, which increases the running time of the device, increases the water retention, and increases the use frequency, which causes the device to be damaged due to overuse, thereby affecting the normal use of the vacuum toilet and failing to meet the current use requirements for the plateau environment.

[0029] To solve the above problems, the embodiment of the present application provides a vacuum suction device, a vacuum toilet and a building cabin, which can switch the operation of the two vacuum pumps according to the actual temperature condition, effectively reducing the damage caused by the long-term high-frequency operation of the vacuum pump, thereby improving the service life of the vacuum suction device, optimizing the use effect of the vacuum toilet, and meeting the use requirements of the building cabin.

[0030] Optionally, the vacuum suction device provided by the embodiment of the present application can not only be arranged in the vacuum toilet, but also can be arranged in various environments such as a washbasin and a bathroom. The vacuum toilet, the washbasin and the bathroom can be arranged in the building cabin, such as the thermal cabin arranged on the plateau, and can also be arranged in a mobile carrier such as an airplane, a high-speed train and a ship.

[0031] Please refer to Figure 1 , Figure 1 The structure schematic diagram of the vacuum suction device provided by the embodiment of the present application can include a controller 110, a first vacuum pump 121, a second vacuum pump 122 and a vacuum tank assembly 130.

[0032] The controller 110 is connected to the first vacuum pump 121 and the second vacuum pump 122, and the controller 110 is used to determine the vacuum pump switching mode according to the acquired temperature information, and control the first vacuum pump 121 or the second vacuum pump 122 to work based on the vacuum pump switching mode. Two independent vacuum pumps are arranged in the vacuum suction device, and the controller 110 connected to the two vacuum pumps determines the vacuum pump switching mode suitable for the current temperature environment according to the acquired temperature information, so as to control the first vacuum pump 121 or the second vacuum pump 122 to work through the determined vacuum pump switching mode.

[0033] Optionally, the controller 110 may be a low-cost control device such as a single-chip microcomputer or a PLC (Programmable Logic Controller) that can realize a control switching function. The first vacuum pump 121 and the second vacuum pump 122 may include various types of vacuum pumps such as a dry screw vacuum pump, a liquid ring vacuum pump, a rotary vane vacuum pump, a diaphragm vacuum pump, a centrifugal vacuum pump, or a combination pump composed of various types of vacuum pumps.

[0034] It should be noted that the temperature information may be data detected by a temperature sensor connected to the controller 110, or may be temperature information obtained by the controller 110 from weather information at the geographic location of the vacuum suction device from the cloud or other terminal devices (such as mobile phones). Temperature information can be detected and obtained regularly to improve the real-time and effectiveness of the vacuum pump switching mode.

[0035] The vacuum tank assembly 130 can be connected to the first vacuum pump 121 and the second vacuum pump 122 through a pipeline. The first vacuum pump 121 and the second vacuum pump 122 are used to control the vacuum degree of the vacuum tank assembly 130. The vacuum tank assembly 130 is used to vacuum the connected water-using device 200 based on the vacuum degree. When the first vacuum pump 121 or the second vacuum pump 122 is working, the vacuum degree of the vacuum tank assembly 130 can be controlled so that the vacuum tank assembly 130 can vacuum the externally connected water-using device 200 based on the change in the vacuum degree.

[0036] Optionally, the degree to which the first vacuum pump 121 and the second vacuum pump 122 control the vacuum degree of the vacuum tank assembly 130 can be adjusted and set according to the air pressure of the external environment, the length of the pipeline, and the viscosity of the waste during discharge. For example, when the vacuum degree reaches -0.5~-0.9 bar, the vacuum assembly can achieve vacuum suction processing.

[0037] For example, the water-using device 200 connected to the outside of the vacuum suction device can be a toilet pit, a toilet, a washbasin, a bathtub in a bathroom, etc. The first vacuum pump 121 and the second vacuum pump 122 can be connected to corresponding water storage tanks to provide the water-using device 200 with the liquid required for cleaning.

[0038] based on Figure 1 In the embodiment shown, the controller 110 switches the operation of the two vacuum pumps according to the actual temperature conditions, thereby effectively reducing the damage caused by long-term high-frequency operation of the vacuum pumps, thereby improving the service life of the vacuum suction device. In addition, in the event of an abnormality caused by environmental influences on a certain vacuum pump, the vacuum suction device can still provide normal vacuum suction function for the externally connected water-using device 200, thereby meeting the suction and cleaning needs in various scenarios.

[0039] Optionally, in order to cope with the low temperature situation existing in the application scene such as plateau, considering the adverse effects of low temperature on the pipeline, the first vacuum pump 121 can be a freeze-proof vacuum pump with a freeze-proof component. The freeze-proof component can include a hoop and a braided elastic pipeline. In the case of ice freezing at low temperature, the ice expansion space under low temperature freezing can be absorbed by the freeze-proof component such as the hoop and the braided elastic pipeline, and the pipeline connection and sealing function can be realized, thereby reducing the damage of the first vacuum pump 121 under low temperature condition (such as pipeline rupture, pipeline freezing, etc.), to prolong the service life of the first vacuum pump 121, and be suitable for various low temperature application scenes.

[0040] For example, the braided elastic pipeline can include a braided rubber tube and other hose devices.

[0041] Optionally, in some application scenarios with high-frequency vacuum suction requirements, for example, the vacuum suction device is arranged in the toilet, pit and other situations of public toilet, in order to meet the high-frequency use requirements, the second vacuum pump 122 can be set as a vacuum pump with high power and high durability.

[0042] Optionally, in some long-time low-temperature application scenarios, the second vacuum pump 122 can also be set as a freeze-proof vacuum pump with a freeze-proof component to adapt to the long-time low-temperature environment.

[0043] It should be noted that the controller 110 is specifically configured to: pre-process the temperature information to obtain temperature data; if it is determined that the temperature data is lower than or equal to a preset low temperature threshold, the controller 110 determines that the vacuum pump switching mode is a low temperature switching mode; if it is determined that the temperature data is greater than or equal to a preset normal temperature threshold, the controller 110 determines that the vacuum pump switching mode is a normal temperature switching mode.

[0044] Optionally, considering the change of the initial temperature information and the like, the controller 110 can first pre-process the temperature information to obtain temperature data with higher effectiveness, and then determine the appropriate vacuum pump switching mode based on the temperature data. The pre-processing method can include summing and mean processing a plurality of temperature information collected within a certain time period, for example, five minutes, to obtain the corresponding average temperature as the temperature data.

[0045] Optionally, in the case that the temperature data is less than or equal to the preset low-temperature threshold, it is characterized that the low-temperature condition occurs, and the low-temperature switching mode can be enabled to switch and control the working states of the two vacuum pumps; in the case that the temperature data is greater than or equal to the preset normal-temperature threshold, it is characterized that the temperature is normal temperature, and the normal-temperature switching mode can be enabled to switch and control the working states of the two vacuum pumps. Different vacuum pump switching modes can be determined according to the actual temperature condition to switch and control the two vacuum pumps, so as to prolong the service life of the two vacuum pumps and ensure the normal function of the vacuum pumping device in abnormal conditions by switching the working mode of the vacuum pump.

[0046] It should be noted that, if the current is the low-temperature switching mode, the low-temperature switching mode can be used all the time until the real-time determined temperature data is greater than or equal to the preset normal-temperature threshold, and then the normal-temperature switching mode is switched to. Correspondingly, if the current is the normal-temperature switching mode, the normal-temperature switching mode can be used all the time until the real-time determined temperature data is less than or equal to the preset low-temperature threshold, and then the low-temperature switching mode is switched to.

[0047] For example, the low-temperature threshold and the normal-temperature threshold can be set and modified according to the actual situation of the environment, for example, the low-temperature threshold can be set to 1-5 degrees Celsius, and the normal-temperature threshold can be set to 15-20 degrees Celsius, etc.

[0048] Optionally, the low-temperature switching mode can include that the first working time ratio of the first vacuum pump 121 to the second vacuum pump 122 is n:1, n is a positive integer greater than or equal to 2 and less than or equal to 5. The controller 110 is specifically configured to: based on the low-temperature switching mode, control the first vacuum pump 121 to start working n times, and then switch to control the second vacuum pump 122 to start working 1 time. In the case of the low-temperature switching mode, since the first vacuum pump 121 is a freeze-proof vacuum pump, the first working time ratio between the first vacuum pump 121 and the second vacuum pump 122 can be set to n:1. In the low-temperature switching mode, the first vacuum pump 121 is controlled to start working n times, and then the second vacuum pump 122 is switched to control to start working 1 time, which is repeated in this way. The higher working frequency of the first vacuum pump 121 can adapt to the low-temperature use environment, and the switching use of the second vacuum pump 122 can reduce the working load of the first vacuum pump 121 due to over-frequency, so as to provide effective vacuum pump function in the low-temperature condition and prolong the service life of the two vacuum pumps.

[0049] Optionally, the normal temperature switching mode can include that the first working time ratio of the first vacuum pump 121 to the second vacuum pump 122 is 1:m, m is a positive integer greater than or equal to 2 and less than or equal to 5. The controller 110 is specifically configured to: based on the normal temperature switching mode, control the second vacuum pump 122 to start working m times, and then switch to control the first vacuum pump 121 to start working 1 time. In the case of the normal temperature switching mode, the second vacuum pump 122 can be set as a vacuum pump with high power and high durability, so the first working time ratio between the first vacuum pump 121 and the second vacuum pump 122 can be set as 1:m. In the normal temperature switching mode, the second vacuum pump 122 is controlled to work m times, and then the first vacuum pump 121 is switched to work 1 time, and the cycle is repeated in this way. The high working frequency of the second vacuum pump 122 can meet the use requirements in the normal temperature environment, and the use of the first vacuum pump 121 can reduce the working load of the second vacuum pump 122 due to over frequency, so as to provide effective vacuum pump function in the normal temperature condition and prolong the service life of the two vacuum pumps.

[0050] Optionally, n and m can be set according to the actual situation of the two vacuum pumps, and can be set as two same values, for example, n=m=3, or can be set as two different values, for example, n=3 and m=4.

[0051] It should be noted that m and n are not set to a large value to reduce the adverse situation of a vacuum pump working too many times in succession.

[0052] It should be noted that in the application scenario of long time low temperature, the application scenarios of the two vacuum pumps are the same, so m and n can also be set to 1 to reduce the damage caused by the use of over frequency of a vacuum pump and other adverse situations through rotation use.

[0053] Optionally, when any vacuum pump generates an abnormal situation and cannot be normally used, the controller 110 can also directly switch to the other vacuum pump for work, and send prompt information to the cloud or terminal device to prompt the abnormal situation of the vacuum pump, so that the staff can handle the abnormal vacuum pump according to the prompt information.

[0054] Optionally, please refer to Figure 2 , Figure 2 Another structure diagram of a vacuum suction device provided by the embodiment of the application is provided. Considering the low difference between the internal and external air pressures in the plateau area and the actual setting situation of connecting a plurality of water using devices 200 to the outside, the vacuum tank assembly 130 can include: a first vacuum tank 131 and a second vacuum tank 132.

[0055] The first vacuum tank 131 is connected with the first vacuum pump 121 and the second vacuum pump 122, the first vacuum tank 131 is connected with the first part of the water-using device 210 in the water-using device 200, the second vacuum tank 132 is connected with the first vacuum pump 121 and the second vacuum pump 122, and the second vacuum tank 132 is connected with the second part of the water-using device 220 in the water-using device 200. The first vacuum tank 131 is used for vacuum suction treatment of the first part of the water-using device 210 based on the first vacuum degree controlled by the first vacuum pump 121 or the second vacuum pump 122, and the second vacuum tank 132 is used for vacuum suction treatment of the second part of the water-using device 220 based on the second vacuum degree controlled by the first vacuum pump 121 or the second vacuum pump 122.

[0056] Optionally, in the case of low atmospheric pressure in the external environment, since the vacuum pump needs to work based on the vacuum negative pressure, low atmospheric pressure may cause insufficient efficiency of the vacuum pump, which is easy to cause the adverse conditions of insufficient suction and reflux. In order to solve this problem, two vacuum tanks can be arranged in the vacuum tank assembly 130, and the two vacuum tanks are respectively connected with the corresponding two vacuum pumps. The first vacuum tank 131 is connected with the first part of the water-using device 210 in the external water-using device 200, and the second vacuum tank 132 is connected with the second part of the water-using device 220 in the external water-using device 200. The vacuum degree of the different vacuum tanks is controlled by the currently working vacuum pump, so as to provide the function of vacuum suction treatment for different parts of the water-using device 200, so as to meet the water cleaning needs of different water-using devices 200.

[0057] For example, compared with the vacuum tank arranged in the plain area, the two vacuum tanks arranged in the application have a larger volume. The vacuum tank can be connected with the vacuum pump and the water-using device 200 through the corresponding vacuum pipeline, so as to realize gas transmission and liquid transmission through the pipeline.

[0058] Optionally, in the case of connecting multiple water-using devices 200 externally, the multiple water-using devices 200 can be divided into the first part of the water-using device 210 and the second part of the water-using device 220, for example, as shown in Figure 2 In the case of having six water-using devices 200, the first part of the water-using device 210 can be three water-using devices 200 numbered 1-3, and the second part of the water-using device 220 can be three water-using devices 200 numbered 4-6.

[0059] Optionally, please continue to refer to Figure 2In order to provide more pressure in the plateau environment, considering the difference in use of the two vacuum tanks, the first vacuum tank 131 can be connected to the second vacuum tank 132 through the connecting pipeline 133, and in the case that the drainage speed of the second vacuum tank 132 does not meet the preset condition, the first vacuum tank 131 is also used to provide gas for the second vacuum tank 132 through the connecting pipeline 133, and in the case that the drainage speed of the first vacuum tank 131 does not meet the preset condition, the second vacuum tank 132 is also used to provide gas for the first vacuum tank 131 through the connecting pipeline 133.

[0060] It should be noted that the preset condition can be set according to actual conditions and requirements, for example, the preset condition can be set to drain 500 milliliters of wastewater per second, or it can also be set to empty the entire vacuum tank within 3 seconds, and in the case that the drainage speed of the second vacuum tank 132 does not meet the preset condition, i.e. the drainage speed is low, the first vacuum tank 131 can provide gas for the second vacuum tank 132 based on the connecting pipeline 133 to increase the drainage speed of the second vacuum tank 132. Correspondingly, in the case that the drainage speed of the first vacuum tank 131 does not meet the preset condition, i.e. the drainage speed is low, the second vacuum tank 132 can provide gas for the first vacuum tank 131 based on the connecting pipeline 133 to increase the drainage speed of the first vacuum tank 131. When the drainage speed of a certain vacuum tank is low, the other vacuum tank can help with drainage, effectively improving the drainage speed when the vacuum tank is in use, and further improving the efficiency of vacuum suction processing under the condition of providing sufficient suction pressure.

[0061] For example, the connecting pipeline 133 can also be provided with a corresponding motor and valve device, and the valve device is used to switch control the conduction between the two vacuum tanks, and the motor is used to control the transmission of the gas. For example, when the drainage speed of the first vacuum tank 131 is low, the valve and the motor are opened, and the motor controls the second vacuum tank 132 to provide gas for the first vacuum tank 131, so that the first vacuum tank 131 can quickly drain wastewater.

[0062] Optionally, the first vacuum tank 131 and the second vacuum tank 132 prefer to meet their own drainage requirements, and only when their own drainage requirements are met will they provide corresponding auxiliary functions for the other vacuum tank.

[0063] Optionally, please continue to refer to Figure 2 In order to process the wastewater discharged by the two vacuum tanks, the vacuum tank assembly 130 can further include a first one-way valve 134 and a second one-way valve 135.

[0064] Among them, the first one-way valve 134 is connected to the first vacuum tank 131, and the first one-way valve 134 is used to unidirectionally output the wastewater discharged from the first vacuum tank 131; the second one-way valve 135 is connected to the second vacuum tank 132, and the second one-way valve 135 is used to unidirectionally output the wastewater discharged from the second vacuum tank 132. Figure 2 The direction of the middle arrow is the one-way output direction of the wastewater. The corresponding one-way valves can be connected after the two vacuum tanks to output the wastewater discharged from the two vacuum tanks to the outside through the one-way valve for corresponding wastewater treatment. The restriction of the one-way valve can reduce the adverse situation of wastewater flowing back to the vacuum tank.

[0067] Optionally, the flush switch 230 may be a flush button or flush key manually controlled by the user, or may be a variety of devices such as a sensor that can automatically detect the user's status to obtain user feedback information.

[0068] Optionally, when the feedback information is that the user presses the flush button or flush key, or the feedback information is that the user is detected to stand up and complete the toilet behavior, the connected vacuum suction device 100 can perform vacuum suction treatment on the water-using device 200 to use vacuum suction technology to treat wastewater and dirt, effectively reducing the water resources required for cleaning the water-using device 200 and reducing the discharge of wastewater, which is suitable for various application environments such as plateaus and mobile carriers.
