Description

Technical Field

[0001] This utility model relates to the field of vacuum negative pressure system technology, and in particular to an integrated intelligent vacuum negative pressure system that integrates a sterilization device. Background Technology

[0002] Since vacuum negative pressure systems are generally connected to various wards and operating rooms in hospitals through pipelines, and the vacuum negative pressure gas is used to remove patients' waste, exhaust gas, or waste liquid, the gas extracted by the vacuum negative pressure system contains germs and harmful substances. According to regulations from hospitals and relevant national departments, the exhaust gas discharged from the hospital's vacuum negative pressure system contains germs and harmful substances and cannot be directly discharged into the atmosphere to avoid secondary pollution. The gas discharged from the vacuum negative pressure system must be sterilized and purified by a sterilization device before it can be discharged into the atmosphere.

[0003] Existing vacuum negative pressure systems are all fixed on simple frames, with internal components exposed, which is not aesthetically pleasing. Modern industrial products not only pursue high quality but also have higher requirements for appearance. Therefore, we designed an integrated vacuum negative pressure system with a casing. This solution houses all components within a single, unified casing. Compared to the previous exposed vacuum negative pressure units, this integrated vacuum negative pressure system with a casing has a much simpler and more aesthetically pleasing appearance.

[0004] Hospital regulations and relevant national regulations stipulate that gases emitted from hospital vacuum negative pressure systems must be sterilized before being released outdoors. Therefore, sterilization devices are essential equipment for vacuum negative pressure systems. Existing sterilization devices are separate from the vacuum negative pressure system, requiring independent installation and control. Installation necessitates rewiring and piping, drilling, connecting power and signal lines, soldering, and other complex procedures, making installation cumbersome and hindering integrated management with the vacuum negative pressure system. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an integrated intelligent vacuum negative pressure system that integrates a sterilization device. The integrated design makes the structure more compact and the appearance more beautiful. The sterilization device and the vacuum negative pressure system are integrated into one device, which reduces the trouble of installing the sterilization device and wiring and piping externally. It also facilitates the centralized control and management of the negative pressure system and the sterilizer, and is also convenient for maintenance and installation.

[0006] To address the aforementioned technical problems, this utility model provides an integrated intelligent vacuum negative pressure system that incorporates a sterilization device, comprising a vacuum pump, a sterilization filter, a sterilization device, an industrial control computer, vacuum pipes, and a housing. The vacuum pump has a vacuum pump inlet, a vacuum pump outlet, a check valve, and an air filter at its upper end. The housing has an inlet at its upper end, which is connected to the sterilization filter via a vacuum pipe. The sterilization filter is connected to the air filter at the upper end of the vacuum pump, the vacuum pump inlet, and the check valve via a vacuum pipe, and is located within the housing cavity. The vacuum pump outlet is connected to the sterilization device via a vacuum pipe and outputs through the housing outlet. The upper end of the housing is equipped with audible and visual alarm lights, and the industrial control computer is located inside. The industrial control computer is connected to the audible and visual alarm lights, the vacuum pump, and the sterilization device via wires.

[0007] Preferably, the top of the housing is provided with one or more cooling fans, which are connected to the industrial control computer via wires.

[0008] Preferably, the lower end of the outer casing is provided with an air inlet slot, which is arranged in an equidistant vertical line.

[0009] Preferably, the internal connecting components of the housing are provided in multiple sets and are connected to each other through vacuum pipes; each set of components is equipped with a vacuum pump inlet and outlet with a vacuum valve.

[0010] Preferably, the sterilization device is equipped with filtration, ultraviolet sterilization, ozone sterilization, high-temperature sterilization, and negative ion purification treatment.

[0011] Using the above technical solution, this utility model provides an integrated intelligent vacuum negative pressure system that incorporates a sterilization device. The air inlet of the outer shell is connected to a vacuum storage tank via a pipe, and the vacuum storage tank is then connected to the gas-using equipment via a pipe to provide a vacuum negative pressure gas source for the equipment requiring vacuum negative pressure. When the vacuum pump is running, the vacuum pump inlet begins to draw in air, which sequentially passes through the inlet, vacuum pipe, sterilization filter, air filter, and check valve into the vacuum pump. Then, the gas discharged from the vacuum pump outlet enters the sterilization device through a pipe. The sterilization device filters, sterilizes, ozone sterilizes, sterilizes at high temperature, and purifies the vacuum negative pressure gas, and then discharges the sterilized and purified gas outdoors through the exhaust port.

[0012] The industrial control computer automatically controls and monitors the operation of vacuum pumps, sterilization devices, and cooling fans. It records and displays the running time, real-time flow rate, real-time vacuum pressure, flow rate curves, operation records, alarm records, and machine information for each vacuum unit. The system also allows for manual parameter settings, enabling fully automatic or manual operation for convenient equipment maintenance and debugging. The upper and lower pressure limits can be manually set; the vacuum pump starts when the pressure in the pipeline is below the lower limit and stops when the pressure exceeds the upper limit. The system features automatic monitoring and alarm functions. When a fault is detected, an audible and visual alarm will sound, alerting personnel to address the problem. It can also manage the operation of the internal sterilization devices and display their operating status.

[0013] The internal vacuum negative pressure system consists of multiple vacuum pump sets (the system can contain two or more other vacuum pumps of any number). Through individual operation, a one-in-one-backup design (or two-in-one-backup, or multiple-in-one-backup) is implemented. Each vacuum pump has vacuum valves at its inlet and outlet. When one vacuum pump malfunctions and requires maintenance, another backup vacuum pump can be activated. Closing the vacuum valves at the inlet and outlet of the pump under maintenance will not affect the operation of the backup pump, ensuring a continuous and stable supply of vacuum negative pressure gas to the hospital. This provides a safety guarantee for the hospital's vacuum negative pressure gas usage and reduces the occurrence of medical accidents.

[0014] Because the components of this vacuum negative pressure system are installed in an integrated housing, and the airflow inside the housing is poor, the housing will affect the heat dissipation of the internal vacuum pump and other components to a certain extent. Therefore, this solution adds one or more cooling fans to the top of the housing. These cooling fans quickly exhaust the heat inside the housing to the outside, and ambient air from outside the housing enters the housing through a slot at the bottom, thus forming a circulation and achieving the purpose of cooling the vacuum pump and internal components. The device has a simple structure and is easy to use. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and examples.

[0023] like Figure 1 , 2 As shown in Figures 3 and 4, an integrated intelligent vacuum negative pressure system that integrates a sterilization device includes a vacuum pump 201, a sterilization filter 202, a sterilization device 203, an industrial control computer 204, a vacuum pipeline 205, and a housing 207.

[0024] The upper end of the vacuum pump 201 is provided with a vacuum pump inlet 101, a vacuum pump exhaust port 102, a check valve 103, and an air filter 104;

[0025] An air inlet 208 is provided at the upper end of the outer casing 207, and the air inlet 208 is connected to the sterilization filter 202 through a vacuum pipe 205. The sterilization filter 202 is connected to the air filter 104 at the upper end of the vacuum pump 201 through the vacuum pipe 205, and is connected to the vacuum pump inlet 101 and the check valve 103, and is located inside the cavity of the outer casing 207. The vacuum pump exhaust port 102 is connected to the sterilization device 203 through the vacuum pipe 205, and is output through the exhaust port 209 of the outer casing 207. When the vacuum pump 201 is running, the vacuum pump inlet... When the air inlet 101 starts to draw in air, the gas will sequentially pass through the housing air inlet 208, vacuum pipe 205, sterilization filter 202, air filter 104, and check valve 103 into the vacuum pump 201. Then, the gas discharged from the vacuum pump exhaust port 102 will enter the sterilization device 203 through the pipe. The sterilization device 203 will filter, ultraviolet sterilize, ozone sterilize, high temperature sterilize, and negative ion purify the vacuum negative pressure gas drawn in. Then, the sterilized and purified gas will be discharged to the outside through the exhaust port 209.

[0026] The upper part of the outer casing 207 is equipped with audible and visual alarm lights 210, and the inner side is equipped with an industrial control computer 204. The system has automatic monitoring and alarm functions. When the equipment detects a fault, the audible and visual alarm lights will emit an audible and visual alarm to remind the staff to handle the equipment fault.

[0027] The industrial computer 204 is connected to the audible and visual alarm light 210, the vacuum pump 201, and the sterilization device 203 via wires;

[0028] The device has two or more sets of internal connecting components, with one set for use and one set for backup (or two sets for use and two sets for backup, or multiple sets for use and multiple sets for backup). Each vacuum pump has a vacuum valve at its inlet and outlet. When one vacuum pump malfunctions and needs maintenance, another backup vacuum pump can be turned on. After the vacuum valves at the inlet and outlet of the vacuum pump under maintenance are closed, the use of the backup vacuum pump will not be affected, ensuring a continuous and stable supply of vacuum negative pressure gas to the hospital, providing safety assurance for the hospital's vacuum negative pressure gas use, and reducing the occurrence of medical accidents.

[0029] Preferably, the top of the housing 207 is provided with one or more cooling fans 212, which are connected to the industrial control computer 204 via wires. Since the airflow inside the housing is relatively poor, the housing can affect the heat dissipation of the internal vacuum pump and other components to some extent. Therefore, this solution adds one or more cooling fans to the top of the housing. These fans quickly exhaust the heat inside the housing to the outside, while ambient air from outside enters the housing through the air inlet, thus forming a circulation and achieving the purpose of cooling the vacuum pump and internal components.

[0030] Preferably, the lower end of the outer casing 207 is provided with an air inlet slot 213, which is arranged in an equal vertical line to facilitate the entry of external gas into the interior of the outer casing.

[0031] Preferably, the housing 207 has multiple sets of internal connecting components, which are connected and communicate with each other through vacuum pipes; each set of components has a vacuum valve 214 at the vacuum pump inlet and outlet for easy maintenance.

[0032] Preferably, the sterilization device 203 is equipped with filtration, ultraviolet sterilization, ozone sterilization, high-temperature sterilization, and negative ion purification treatment.

[0033] In use: The outer casing's air inlet is connected to a vacuum storage tank via a pipe. The vacuum storage tank is then connected to the equipment requiring vacuum pressure via a pipe, providing a vacuum negative pressure source for the equipment. When the vacuum pump is running, the vacuum pump's air inlet begins to draw in air. The gas sequentially passes through the air inlet, vacuum pipe, sterilization filter, air filter, and check valve into the vacuum pump. Then, the gas discharged from the vacuum pump's exhaust port enters the sterilization device through a pipe. The sterilization device filters, sterilizes, ozone sterilizes, sterilizes at high temperature, and purifies the vacuum negative pressure gas it draws in, and then discharges the sterilized and purified gas outdoors through the exhaust port.

[0034] The industrial control computer automatically controls and monitors the operation of vacuum pumps, sterilization devices, and cooling fans. It records and displays the running time, real-time flow rate, real-time vacuum pressure, flow rate curves, operation records, alarm records, and machine information for each vacuum unit. The system also allows for manual parameter settings, enabling fully automatic or manual operation for convenient equipment maintenance and debugging. The upper and lower pressure limits can be manually set; the vacuum pump starts when the pressure in the pipeline is below the lower limit and stops when the pressure exceeds the upper limit. The system features automatic monitoring and alarm functions. When a fault is detected, an audible and visual alarm will sound, alerting personnel to address the problem. It can also manage the operation of the internal sterilization devices and display their operating status.

[0035] The internal vacuum negative pressure system consists of multiple vacuum pump sets (the system can contain two or more other vacuum pumps of any number). Through individual operation, a one-in-one-backup design (or two-in-one-backup, or multiple-in-one-backup) is implemented. Each vacuum pump has vacuum valves at its inlet and outlet. When one vacuum pump malfunctions and requires maintenance, another backup vacuum pump can be activated. Closing the vacuum valves at the inlet and outlet of the pump under maintenance will not affect the operation of the backup pump, ensuring a continuous and stable supply of vacuum negative pressure gas to the hospital. This provides a safety guarantee for the hospital's vacuum negative pressure gas usage and reduces the occurrence of medical accidents.

[0036] Because the components of this vacuum negative pressure system are installed within an integrated housing, and the airflow inside the housing is poor, the housing can negatively impact the heat dissipation of the internal vacuum pump and other components. Therefore, this design adds one or more cooling fans to the top of the housing. These fans rapidly exhaust heat from inside the housing to the outside, while ambient air from outside enters through a slot at the bottom of the housing, creating a circulation that cools the vacuum pump and internal components. The vacuum pump has an air inlet, an air outlet, a check valve, and an air filter at its top. The housing has an air inlet at its top, connected to a sterilization filter via a vacuum pipe. The sterilization filter is connected to the air filter at the top of the vacuum pump via a vacuum pipe, which is also connected to the vacuum pump inlet and the check valve, and is located within the housing cavity. The vacuum pump exhaust port is connected to the sterilization device via a vacuum pipe and outputs through the housing exhaust port. When the vacuum pump is running, the air inlet begins to draw in air, which sequentially passes through the housing inlet, the vacuum pipe, the sterilization filter, and the air filter. The filter and check valve enter the vacuum pump, and the gas discharged from the vacuum pump's exhaust port enters the sterilization device through a pipeline. The sterilization device filters, sterilizes with ultraviolet light, ozone, and high temperature, and purifies the vacuum gas by negative pressure. The sterilized and purified gas is then discharged outdoors through the exhaust port. The upper part of the outer casing is equipped with audible and visual alarm lights, and an industrial control computer is located inside. This system has automatic monitoring and alarm functions. When the equipment detects a fault, the audible and visual alarm lights will emit an audible and visual alarm to remind personnel to handle the equipment malfunction. The industrial control computer is connected to the audible and visual alarm lights, vacuum pump, and sterilization device via wires.

[0037] This utility model provides an integrated intelligent vacuum negative pressure system that integrates a sterilization device. The integrated design makes the structure more compact. The integration of the sterilization device and the vacuum negative pressure system reduces the trouble of installing the sterilization device separately and wiring and piping. It also facilitates centralized control and management of the negative pressure system and the sterilizer, and is easy to maintain and install. The device has a simple structure and is practical and convenient.

[0038] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
