Further, the negative pressure air suction device comprises an air suction cover arranged above the dining position and a fan connected with the air suction cover.
Further, the dining table separating device is used for separating adjacent dining tables.
Further, the meal position isolating device is an isolating plate.
Further, the harmful bacteria and virus protection device also comprises a bracket for supporting the air suction cover.
Further, the harmful bacteria or/and viruses removing device is a filtering device which removes harmful bacteria or/and viruses by adopting a filtering mode, or the harmful bacteria or/and viruses removing device is a high-temperature sterilizing device which kills the harmful bacteria or/and viruses through high temperature.
The invention has the beneficial effects that:
1. according to the method and the device for protecting harmful bacteria and viruses during dining, the dining positions adjacent to each other are isolated by the dining position isolation device, and the negative pressure is formed at the dining positions, so that the droplets or aerosol generated by the dining personnel are quickly sucked into the exhaust pipe above the dining positions, the droplets or aerosol with harmful bacteria or/and viruses are prevented from being diffused to the periphery, and the problem that the aerosol or aerosol generated by the dining personnel carrying the viruses or harmful germs infect other people or food nearby is avoided.
2. According to the method and the device for protecting harmful bacteria and viruses during dining, harmful bacteria and/or viruses contained in the air are eliminated by filtering or killing the air sucked into the pipeline at high temperature, and the sterilized air is discharged at a place far away from a dining environment, so that the technical problem that the air flow near a dining position is disordered due to the fact that the sterilized air is discharged from the accessories of the dining position, and the air near the dining position is further sucked away by the negative pressure air suction device is solved.

Detailed Description
The invention is further described below with reference to the figures and examples.
According to the method for preventing the harmful bacteria and the viruses during dining, low air pressure is generated at the dining position to suck air at the dining position into the exhaust pipe, the harmful bacteria or/and the viruses contained in the air in the exhaust pipe are eliminated in a filtering or killing mode, and finally the air after the harmful bacteria or/and the viruses are eliminated in the exhaust pipe is exhausted in the environment far away from the dining position.
The device for protecting harmful bacteria and viruses during dining in the embodiment comprises a negative pressure air suction device 1 arranged at a dining position, an exhaust pipe 2 connected with the negative pressure air suction device, and a harmful bacteria or/and virus eliminating device 3 connected with the exhaust pipe.
The device for preventing harmful bacteria and viruses during dining in the embodiment further comprises a dining position isolating device 4 for isolating adjacent dining positions. The meal position isolating device is an isolating plate, the shape of the isolating plate can be designed according to the number of the dining table and the meal positions, and the isolating plate can be a Chinese character 'Wang' shaped isolating plate, an I-shaped isolating plate and the like. The isolation plate can prevent the spray and aerosol generated by diners from diffusing to the adjacent dining positions.
In this embodiment, negative pressure getter device is including setting up the cover 11 of breathing in above the position of having dinner and the fan 12 of being connected with the cover of breathing in, utilizes the fan to produce the negative pressure, and the cover of breathing in is located personnel's of having dinner head top, can be with the quick suction blast pipe of airflow around the personnel of having dinner, and the flow direction of locating the airflow at the position of having dinner is from upwards down, consequently has avoided the spray or the aerosol that personnel of having dinner produced to diffusion all around to the effect of isolation protection has been played.
In this embodiment, the negative pressure suction device further includes a support 5 for supporting the suction hood, and the support facilitates installation of the negative pressure suction device.
In this embodiment, the harmful bacteria or/and viruses removing device is a filtering device that removes harmful bacteria or/and viruses by filtering.
