[0027] See attached Figure 1 As shown, the utility model provides a technical solution: a negative pressure suction disinfection system, comprising a sub-cylinder 10, a suction pipeline 20, a negative pressure pipeline 30 and an ozone generator 40; the suction pipeline 20 comprises a vacuum pump 21, a control valve 22 and a first filter 23 which are sequentially connected through a first suction pipeline 201, the output end of the vacuum pump 21 is connected to the exhaust pipeline 202, and the first filter 23 is connected to the sub-cylinder 10 through a second suction pipeline 203; the negative pressure pipeline 30 comprises at least one negative pressure suction terminal 31, and at least one negative pressure suction terminal 31 is connected to the negative pressure pipeline 301 through a negative pressure pipeline 301; the ozone generator 40 is connected to the sub-cylinder 10 through an ozone pipeline 401.

[0028] Illustratively, the vacuum pump 21 , the control valve 22 , the first filter 23 and the suction line 20 may be one or more.

[0029] According to this embodiment, during routine disinfection, the control valve 22 is in an open state, and the vacuum pump 21 draws the first suction pipe 201, the second suction pipe 203 and the negative pressure pipe 301 to negative pressure. The gas in the ward is sucked into the first filter 23, and after the gas is filtered by the first filter 23, the waste gas is discharged through the exhaust pipe 202. During the disinfection of each pipeline, the control valve 22 is in a closed state, and the ozone generator 40 generates ozone gas. The ozone gas flows into the second suction pipe 203, the first suction pipe 201 and the negative pressure pipe 301 through the ozone pipe 401, and the bacteria and viruses remaining in each pipeline can be disinfected and killed, and the residual bacteria, viruses and droplets are prevented from being discharged into the atmosphere. After the residual bacteria and viruses are disinfected, the control valve 22 is opened and the vacuum pump 21 is started, so that the waste gas can be discharged through the exhaust pipe 202.

[0030] Refer to the attached Figures 1-2 As shown, in some embodiments, the suction line 20 includes a second filter 24 , the second filter 24 is connected to the first suction pipe 201 , and the second filter 24 is located between the control valve 22 and the first filter 23 .

[0031] According to this embodiment, during routine disinfection, the double filter configuration can filter both bacteria and viruses in the gas and droplets in the gas, thereby preventing bacteria, viruses, droplets, etc. from being discharged into the atmosphere.

[0032] Refer to the attached Figures 1-2 As shown, in some embodiments, the suction pipeline 20 may further include a buffer tank 25 , the buffer tank 25 is connected to the second suction pipeline 203 , and the buffer tank 25 is connected to the sub-cylinder 10 through the third suction pipeline 204 .

[0033] According to this embodiment, the buffer tank 25 is pumped to negative pressure by the vacuum pump 21. During routine disinfection, the negative pressure of the buffer tank 25 is consumed to maintain negative pressure in the first suction pipe 201, the second suction pipe 203 and the negative pressure pipe 301, thereby sucking the gas in the ward. In this way, the buffer tank 25 plays a buffering role for the vacuum pump 21, preventing the vacuum pump 21 from being started and stopped continuously.

[0034] Refer to the attached Figures 1-2 As shown, in some embodiments, the suction pipeline 20 may further include a control cabinet 26 , the control valve 22 is a solenoid valve, and the vacuum pump 21 and the solenoid valve are both electrically connected to the control cabinet 26 .

[0035] According to this embodiment, the control cabinet 26 can control the vacuum pump 21 and the solenoid valve to realize automatic opening and closing of the vacuum pump 21 and automatic opening and closing of the solenoid valve.

[0036] Refer to the attached Figure 1 and 3 As shown, in some embodiments, the suction pipeline 20 may further include a negative pressure sensor 27 , and the negative pressure sensor 27 is connected to the buffer tank 25 through a connecting pipe 251 , and the negative pressure sensor 27 is electrically connected to the control cabinet 26 .

[0037] According to this embodiment, the negative pressure sensor 27 is used to detect the pressure of the buffer tank 25. When the buffer tank 25 reaches the first preset negative pressure threshold, the control cabinet 26 controls the vacuum pump 21 to stop working, thereby preventing the buffer tank 25 from being over-pressurized and causing a safety accident. When the buffer tank 25 is lower than the second preset negative pressure threshold, the control cabinet 26 controls the vacuum pump 21 to start working, so that the pressure of the buffer tank 25 is maintained at the first preset negative pressure threshold, so that the first suction pipe 201, the second suction pipe 203 and the negative pressure pipe 301 can perform the disinfection work normally.

[0038] Refer to the attached Figure 1 and 3 As shown, in some embodiments, the suction pipeline 20 may further include a negative pressure gauge 28 , which is connected to the connecting pipeline 251 .

[0039] According to this embodiment, the negative pressure meter 28 is used to display the current negative pressure value, so that the staff can timely understand the operating status of the buffer tank 25. When the buffer tank 25 fails, it is convenient for the staff to perform maintenance in time.

[0040] Refer to the attached Figure 1 As shown, in some embodiments, the negative pressure pipeline 30 may further include an ozone concentration detector 32 , which is connected to a negative pressure suction terminal 31 , and the ozone concentration detector 32 is communicatively connected to the ozone generator 40 .

[0041] Exemplarily, the ozone concentration detector 32 can communicate with the ozone generator 40 via a wireless network. For example, the ozone concentration detector 32 can communicate with the ozone generator via a 4G network or a 5G network.

[0042] According to this embodiment, the ozone concentration detector 32 is used to detect the ozone concentration of each pipeline. After the ozone concentration detector 32 transmits the ozone concentration back to the ozone generator 40, the ozone generator 40 can control the ozone flow and working time of each pipeline.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
