[0049] Further, the system can also be provided with a display device, which can be a touch display screen 1 connected with the main control board 2, for displaying the negative pressure monitored by the pressure sensor 4 and the air quality information monitored by the air quality sensor 6.

[0050] Embodiment 2

[0051] Based on the pressure storage smoke exhaust purification system in Embodiment 1, this embodiment provides a pressure storage smoke exhaust purification system, as shown in the figure, which includes a display device, a control assembly, an air inlet 31, a negative pressure filter container 33, a drying module 34, a negative pressure device 35, an air filter 36, an air outlet 37, an air quality sensor 6, a disposable filter 8, and a UV lamp 7. Figure 2

[0052] Specifically, under the action of the negative pressure device 35, the gas enters the pressure storage smoke exhaust purification system from the air inlet 31, passes through the disposable filter 8, enters the negative pressure filter container 33 above the liquid level through the air inlet pipe 332, the negative pressure filter container 33 in this embodiment can be a negative pressure filter bottle, then exits the negative pressure filter container 33 through the air outlet pipe 333 to enter the drying module 34, and then is sucked into the negative pressure device 35, continues to pass through the air filter 36, after leaving the air filter 36, collects information through the air quality sensor 6 and receives sterilization by the UV lamp 7, and is discharged from the pressure storage smoke exhaust purification system through the air outlet 37.

[0053] Among them, the air inlet 31, the negative pressure filter container 33, the drying module 34, the negative pressure device 35, the air filter 36, and the air outlet 37 are connected through air path hoses, the air quality sensor 6 is arranged after the air filter 36, and can be arranged between the air filter 36 and the air outlet 37, or arranged at the air outlet 37.

[0054] Specifically, in this embodiment, the display device is a touch display screen 1, the control assembly includes a main control board 2, a pressure sensor 4, and an electromagnetic valve 32, the touch display screen 1 is connected with the main control board 2 through a serial port, the main control board 2 is connected with the electromagnetic valve 32, the negative pressure device 35 in the air path assembly, and the pressure sensor 4 through a circuit, and the pressure sensor 4 communicates with the air above the negative pressure filter container 33 in the air path assembly. Among them, the electromagnetic valve 32 is arranged at the air inlet pipe 332 of the negative pressure filter container 33 as a switch of the air inlet pipe 332.

[0055] Specifically, the process of the pressure storage smoke exhaust purification system in this embodiment for exhaust is as follows: ​

[0056] When the electromagnetic valve 32 is closed, the negative pressure device 35 is opened to draw air, and a negative pressure is gradually formed above the liquid surface of the negative pressure filter container 33. After a preset time, the electromagnetic valve 32 is opened, because the pressure in the negative pressure filter container 33 is significantly lower than the atmospheric pressure, the surgical smoke is filtered into the sterilization liquid in the negative pressure filter container 33 from the exhaust port 37, and then the pressure in the liquid surface of the negative pressure filter container 33 is balanced. At this time, because the negative pressure device 35 continues to draw air, the surgical smoke above the liquid surface of the negative pressure filter container 33 is absorbed by the drying module 34, and then enters the air filter 36 through the negative pressure device 35 to further filter out particulate matter and harmful gases, and then the information is collected by the air quality sensor 6, and then discharged from the exhaust port 37.

[0057] Further, the opening and closing of the electromagnetic valve 32 and the operation of the negative pressure device 35 are controlled by the main control board 2, and the main control board 2 receives the instructions received by the touch display screen 1 and controls through electrical signals. Preferably, the negative pressure device 35 can also be opened or closed by a foot switch.

[0058] Further, during the smoke exhaust process, the air above the liquid surface of the negative pressure filter container 33 is connected to the pressure sensor 4, and the pressure is monitored in real time. In this embodiment, the air above the liquid surface of the negative pressure filter container 33 is connected to the pressure sensor 4 through a pressure measuring pipe 331. The pressure information monitored by the pressure sensor 4 and the air quality information monitored by the air quality sensor 6 are both sent to the main control board 2, and the main control board 2 converts these information into visual information and sends it to the touch display screen 1 for display, so that the user can input instructions according to these information.

[0059] Further, the process of filtering the surgical smoke by the negative pressure filter container 33 is based on that the sterilization liquid in the liquid surface of the negative pressure filter container 33 can filter and eliminate the particulate matter and part of the harmful gases contained in the inhaled smoke. Preferably, the negative pressure filter container 33 is washable and easy to clean.

[0060] The process of drying the surgical smoke filtered by the negative pressure filter container 33 by the drying module 34 is based on that the drying module 34 includes multiple levels of drying pipes, including a first level of drying pipe 341 and a second level of drying pipe 342, and each drying pipe is filled with different drying agents to dry the water vapor in the air after the negative pressure filter container 33, avoid the sterilization liquid from entering the subsequent device to cause damage and pollution, ensure the dry and wet separation in the system to protect the safety of the circuit, prolong the service life of each device, and ensure the smoke exhaust effect. Preferably, the drying module 34 also includes a drying module replacement window 340 for replacement and easy replacement.

[0061] The air quality information collected by the air quality sensor 6 includes the content of particulate matter and organic volatile matter in the exhaust gas, which is used as feedback of whether the smoke exhaust treatment is perfect.

[0062] The air filter 36 further filters the surgical smoke. The air filter 36 includes a fiber layer and an adsorption layer. The fiber layer can capture tiny particles in the air, such as bacteria, viruses, etc. The adsorption layer can absorb and remove harmful gases and odors in the air. The air filter 36 has an air filter replacement window 361. Whether the air filter needs to be replaced is determined according to the air quality information monitored by the air quality sensor 6.

[0063] During the air extraction process of the negative pressure device 35, the power of the negative pressure device 35 can be adjusted, so that the smoke extraction speed can be controlled according to the demand, and more application scenarios are provided for the pressure storage smoke extraction and purification system.

[0064] The disposable filter 8 is arranged at the air inlet 31 to perform primary filtration on the air entering the system. The ultraviolet lamp 7 is arranged at the air outlet 37 to perform secondary sterilization on the air discharged from the system. By arranging the two components, the smoke extraction quality can be further optimized.

[0065] In summary, based on the pressure storage smoke extraction and purification system described in Embodiment 1, the touch display screen 1, the main control board 2, the pressure sensor 4, the pressure measuring pipe 331, the drying module 34, the air filter 36, the air filter replacement window 361, the air quality sensor 6, the ultraviolet lamp 7, and the disposable filter 8 are added. Among them, the addition of multiple filtering links optimizes the filtering effect of the filtering system. The arrangement of the control components and the display device not only makes the information in the smoke extraction process of the system visualized, but also facilitates the user to control the pressure storage smoke extraction and purification system according to the information, and overall improves the smoke extraction efficiency of the pressure storage smoke extraction and purification system.

[0066] Embodiment 3

[0067] The embodiment provides a pressure storage smoke extraction and purification device, which includes a movable cabinet, and the cabinet is internally provided with the pressure storage smoke extraction and purification system described in Embodiment 2. The cabinet meets the demand of the user to move the purification device in the operating room or other places, so that the purification device is more convenient to use and has a wider application scenario.

[0068] Specifically, as shown in Figure 3 the touch display screen 1, a handle, the air inlet 31, the disposable filter 8, the drying module 34, and a roller. The touch display screen 1 is arranged at the top end of the cabinet shell 5. The handle for dragging the cabinet is arranged at one side of the top end of the cabinet shell 5. The air inlet 31 in the form of a long pipe extends from the cabinet shell 5. The disposable filter 8 is arranged at the end of the air inlet 31 close to the cabinet shell 5. The negative pressure filtration container 33 is arranged in the cabinet and connected with the air inlet pipe 332, the air outlet pipe 333, and the pressure measuring pipe 331. The drying module 34 is arranged below the negative pressure filtration container 33 in the cabinet. The roller is arranged at the bottom of the cabinet and used for moving the cabinet.

[0069] like Figure 4 As shown, the chassis also includes an exhaust port 37, a UV lamp 7, an air quality sensor 6, and a foot switch. The exhaust port 37 is designed as an exhaust cavity 371, which houses the UV lamp 7 and air quality sensor 6. The air filter 36 and air filter replacement window 361 are located below the exhaust port 37. The foot switch is located between the rollers at the bottom of the chassis housing 5.

[0070] Furthermore, the chassis also includes a negative pressure device 35 located between the drying module 34 and the air filter 36, a main control board 2 connected to the touch screen 1, a solenoid valve 32 connected to the air intake pipe 332, and a pressure sensor 4 connected to the pressure measuring pipe 331. These components can be placed anywhere within the chassis, provided that the smoke exhaust effect of the pressure-accumulating smoke purifier is not affected and the assembly is reasonable.

[0071] Specifically, the process of exhausting smoke by the pressure-accumulated smoke purifier includes: before the operation begins, the chassis of the pressure-accumulated smoke purifier is moved to a position where the air inlet pipe 332 can easily absorb surgical smoke. When the solenoid valve 32 is closed, the negative pressure device 35 is opened to extract air, and a negative pressure is gradually formed above the liquid surface of the negative pressure filter container 33. After a preset time, the solenoid valve 32 is opened. Because the pressure in the negative pressure filter container 33 is significantly lower than the atmospheric pressure, the surgical smoke instantly enters the chassis from the air inlet 31, enters the disinfectant liquid in the negative pressure filter container 33 through the air inlet pipe 332, and is filtered. After that, it enters the air above the liquid surface to balance the pressure. At this time, because the negative pressure device 35 continues to extract air, the surgical smoke above the liquid surface of the negative pressure filter container 33 absorbs moisture through the drying module 34, passes through the negative pressure device 35, enters the air filter element 36, and further filters out particulate matter and harmful gases. Then, after the air quality sensor 6 collects information, it is discharged from the exhaust port 37.

[0072] Furthermore, during surgery, the user can use the touchscreen display 1 on the chassis to monitor the negative pressure within the negative pressure filter container 33 and the final air quality after smoke extraction. This allows the user to control the pressure-accumulated smoke extraction and purification system by inputting instructions or pressing a foot switch based on smoke extraction requirements. The user can also adjust the position of the chassis, and thereby the position of the air inlet 31 for surgical smoke intake, to ensure optimal smoke extraction performance.

[0073] Example 4

[0074] This embodiment provides a pressurized smoke exhaust purification method based on the pressurized smoke exhaust purification system of embodiment 1, which specifically includes any one or a free combination of three working modes, wherein the three working modes are normal working mode, preparatory working mode and circulating pressure storage working mode.

[0075] Among them,Figure 5 As shown in FIG, the process of the preparatory working mode includes:

[0076] S501 , close the on / off solenoid valve 32 of the intake pipe.

[0077] S502: Turn on the negative pressure device 35 to accumulate pressure.

[0078] S503: Open the switch solenoid valve 32 of the air intake pipe to exhaust smoke.

[0079] Specifically, the negative pressure device 35 is turned on to extract air while the solenoid valve 32 is closed for a preset time, so that the air pressure above the liquid level of the negative pressure filter container 33 is negative pressure. When the air needs to be exhausted, the solenoid valve 32 is opened, and the air inlet pipe 332 of the negative pressure filter container 33 draws air from the air inlet 31. After a period of transition, it enters the normal working mode. This mode can achieve the effect of instantly clearing a large amount of surgical smoke.

[0080] like Figure 6 As shown, the normal working mode process is similar to the common smoke exhaust equipment working mode, including:

[0081] S601: Open the on / off solenoid valve 32 of the intake pipe.

[0082] S602: Start the negative pressure device 35 to exhaust smoke.

[0083] like Figure 7 As shown in FIG, the process of the cyclic pressure storage working mode includes:

[0084] S701. Turn on the negative pressure device 35.

[0085] S702: Control the opening and closing of the air intake pipe according to an open-close cycle to exhaust smoke.

[0086] Specifically, the user is first required to pre-set the opening and closing cycle of the solenoid valve 32 on the touch screen 1, that is, the solenoid valve 32 is opened for a period of time and then closed for a period of time, and the negative pressure device 35 is kept open to perform the opening and closing cycle of the solenoid valve 32. This working mode is equivalent to periodically closing the solenoid valve 32 briefly in the normal working mode. During the time when the solenoid valve 32 is briefly closed, a large negative pressure is formed above the liquid level of the negative pressure filter container 33, so that when the solenoid valve 32 is opened again, the surgical smoke can be quickly inhaled for smoke exhaust treatment. Compared with the working modes of other smoke exhaust equipment, this mode can increase the smoke exhaust speed by 30% at the same smoke exhaust flow rate. Preferably, based on actual test data, in the opening and closing cycle of the solenoid valve 32, the opening time of the solenoid valve 32 should be much greater than the closing time, so as to ensure the working efficiency of the pressure storage smoke exhaust purification system over a long period of time.

[0087] The smoke purification system and the purifier provided by the utility model can form negative pressure in the negative pressure filtering container, inhale the balanced pressure of the surgical smoke during use, and can realize more efficient smoke exhaust and reduce the harm of the surgical smoke.

[0088] It should be noted that, according to the needs of implementation, each step / component described in the present application can be split into more steps / components, or two or more steps / components or part of the operation of the steps / components can be combined into a new step / component, to achieve the purpose of the utility model.

[0089] The size of the serial number of each step in the above embodiment does not mean the order of execution, and the execution order of each process should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0090] It should be understood that, for those skilled in the art, improvements or changes can be made according to the above description, and all these improvements and changes shall belong to the protection scope of the claims attached to the utility model.
