Recent studies have also shown that aerosol transmission is the main route of transmission of the coronavirus. Omicron has a very strong transmission power, and preventing air transmission is the top priority.
Aerosol refers to a system composed of solid or liquid particles suspended in a gas medium with a diameter of between 0.001 and 100 μm. The coronavirus with a diameter of about 0.1 μm can attach to dust and droplets, or "airborne" in the form of aerosols on droplet nuclei that lose moisture.
The air disinfection robot equipment produced by BooCax, as a developer of new disinfection technology can instantly disinfect rooms and public environments in one process, which can reduce the infection rate of coronavirus caused by aerosol transmission. The main working principle is to send the atomized acidic disinfection water mist into the air to make it fully diffuse, and the disinfectant with a certain concentration can sterilize the suspended particles (aerosol) in the air; the suspended particles absorb the supersaturated water mist. Afterwards, the sedimentation is accelerated due to gravity, and at the same time it plays a role in air purification. Disinfection robots disinfect public places with huge traffic such as shopping malls, airports, office buildings and other areas, mainly because of automation and significant cost savings by reducing cleaning personnel, and more importantly, it can effectively block the aerosol of the coronavirus spread, greatly reducing the cross-infection rate in dense populations.
Recently, a cluster of epidemics occurred in Beijing, the capital of China. During the May 1st long holiday when the "epidemic" war in the capital Beijing was in progress, a number of BooCax air disinfection and disinfection robots were urgently "on duty" at Beijing North Railway Station, serving Beijing Zhang, Beijing Bao, and suburban areas. Passengers on Huairou, Miyun and other lines travel normally, providing a strong epidemic prevention guarantee. Beijing North Railway Station is an important part of the capital railway hub, with a total construction area of about 21,400 square meters. There are 3 ticket halls, with six floors above ground and two underground floors. It is connected to Beijing Metro Line 2/4/13 for transfer. The flow of people and vehicles is huge, and the epidemic prevention environment is extremely complicated.
The disinfection robot in Beijing North Railway Station "on duty" this time is a 2022 new product of Bubble Fish independently developed by the company. It has the following characteristics:
1. Small and flexible body design
The newly upgraded 2nd-generation Bubble Fish atomization and disinfection robot adopts a more compact whole machine design, which improves the passability of the body to the narrowest passing width of 60 cm; at the same time, it greatly reduces the risk of collision caused by various accidents, and relatively improves the safety of use .
2. Possess the capability of terminal disinfection of hospital infection
BooCax Bubble Fish disinfection robot can use H2O2-based high-performance disinfectant to sterilize all indoor air; the disinfection principle is to atomize the hydrogen peroxide Disinfection solution "floats" in the air, which can kill a large number of pathogenic microorganisms, and plays a role in disinfection on various surfaces, especially on hidden surfaces that cannot be cleaned, so it can prevent infection and greatly reduce disinfection costs. , is a good choice to reduce the incidence of nosocomial infection.
At the same time, the products of hydrogen peroxide atomization and disinfection are water and oxygen, and there will be no residual liquid medicine, and will not cause damage to the equipment in the ward, department, and operating room;
3. Add visual obstacle avoidance and intelligent navigation to build a map
The upgraded atomization disinfection robot greatly improves the flexibility of the robot's own movement. Once an obstacle less than 30 cm in front is detected, it can quickly adjust the direction, avoid the obstacle and continue the disinfection work, which indirectly improves the indoor disinfection operation environment. Adaptability to better ensure the ability to implement intelligent disinfecting.
4. Supporting chlorine dioxide, hydrogen peroxide (concentration<8%), hypochlorous acid and other disinfectants
Air disinfection, environmental disinfection; no pollution, no residue
The stock solution, directly loaded for use, is food-grade safe; the loading amount is determined by the disinfecting area
Air disinfection, environmental disinfection; no pollution, no residue, in addition to sterilization, it can also remove odors
Concentration: The effective chlorine content of the disinfectant after being diluted into clean water for activation is 100~500mg (according to the manufacturer's ratio).
When spraying is used for air disinfection and surface disinfection, the concentration of the disinfectant is recommended to be no less than 250mg/L, and the action time is recommended to be no less than 30 minutes. (The higher the concentration, the stronger the disinfection power.)

Disinfection and sterilization of CDC, ward and isolation area
Laboratory disinfection, biological safety cabinet sterilization
Nucleic acid detection PCR laboratory disinfection, accounting for aerosol removal
5.12L capacity solution tank, spray volume up to 2.6L/h (adjustable)
Compared with other types of spray disinfection robots from BooCax, the Bubble Fish autonomous disinfection robot has a small body, but it can still have a water tank capacity of 12L, which is comparable to the industry's first capacity. The adjustable spray volume button design also fully meets different requirements. Spray volume required at disinfection level .
6. The fully charged state can work continuously for 1.6h~2.8h hours (measured data)
The 2002 version of the "Disinfection Technical Specifications" stipulates that in the case of the ultra-low volume spray disinfection method, the action time needs 30-60 minutes to achieve the disinfection effect. The Bubble Fish disinfection robot needs 3 hours to be fully charged each time, and the longest battery life is 2.8 hours. , fully meet the needs of disinfection time, and can achieve the best disinfection effect.
7. The disinfection ability can cover 500m³ space without dead ends, which is equivalent to the workload of 2-3 epidemic prevention personnel
The original disinfection is mainly manual disinfection. The limited human and physical energy and disinfection tools make the disinfection work relatively slow and the disinfection effect cannot be guaranteed. The new bubble fish disinfection robot is 360-degree rotation, autonomous movement and APP. It can record disinfection logs and other functions, which greatly improves the efficiency of disinfection. There is no doubt that a disinfection robot can replace the workload of 2-3 epidemic prevention personnel, and it can reduce the cross-infection rate caused by manual disinfection.
8. It can be recharged automatically when the battery is low, and no manual participation is required in the whole process of disinfection
The robot APP independently developed by BooCax can fully operate the robot's construction map, route deployment, switching map, disinfection log tracking, setting timed disinfection/instant disinfection work including troubleshooting, etc.; during the disinfection process, no manual participation is required, and it is intelligent and efficient. And it is a good helper for air disinfection in major public environments.
According to the professional testing results of the Beijing Academy of Science and Technology, the average atomization particle value of the new Bubble Fish is 4.23 μm, which is much higher than the average atomization technology average of 10 μm for competing products in the industry. The size of the particle value is one of the core indicators to measure the disinfecting performance of the robot. The disinfecting robot generally works indoors, and the air temperature, humidity and airflow are relatively stable. Referring to the principle of Brownian motion, the floating time in the air is longer, as shown in the following table. ; As the particle size becomes smaller, the number of particles per milliliter of disinfectant increases significantly, and the medicament is fully utilized. Small particles of disinfectant diffuse faster indoors, and the longer the floating time is, the longer it will hit the new coronavirus in the air. The probability is also increasing exponentially, and the disinfecting will be more thorough.
More robots serving global markets
BooCax's sanitation robot is now on the market, and we have produced and sold a lot, said Zhang, COO. "We have received many orders from domestic hospitals, subways, schools and other scenarios, but the delivery time is longer - four weeks." The new robot has CE certification, CMA report, including PICC insurance, fully guaranteeing customers' safety Benefit;
In addition, in order to meet the needs of special professional scenarios, the BooCax team has also developed a 254nm UV disinfection robot.
