DETAILED DESCRIPTION

[0027] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-6 As shown, the present invention provides an air purification and disinfection robot 100, including a robot body 1, a purification device 2 and a disinfection device 3; the robot body 1 is provided with a cavity 11 inside, and an air inlet 12 and an air outlet 13 are provided on the robot body 1, and the air inlet 12 and the air outlet 13 are both connected to the cavity 11; the purification device 2 is arranged inside the cavity 11, and air enters the purification device 2 from the air inlet 12, and the air from the purification device 2 flows out from the air outlet 13; the disinfection device 3 includes a container 31 for disinfectant liquid and at least one spraying member 32, the container 31 is located in the cavity 11, each spraying member 32 is installed on the robot body 1, and the spraying member 32 is connected to the container 31 through a pipeline.

[0029] In the above technical scheme, the specific structure of the robot body 1 and the purification device 2 is not limited. In some embodiments, the robot body 1 can be designed to have the following three features: 1. Sensing function: once a person is detected approaching, the illumination angle of the light on the robot is immediately adjusted to avoid direct illumination of the human body and ensure the safety of the personnel; 2. Environmental protection and energy saving: sodium ion battery monomer technology is adopted, which is environmentally friendly, low cost, and provides energy guarantee with high endurance. At the same time, it has a self-insulating battery management module to adapt to different temperature environments; 3. Multi-scenario applicability: the robot design takes into account the applicability of multiple scenarios and can perform air purification and disinfection operations in various environments such as hospitals, schools, subway stations, and public places. In some embodiments, the robot can cruise autonomously without tracks, that is, based on the robot global positioning technology of laser radar SLAM and the path planning algorithm of improved Q learning, the robot can realize autonomous navigation and obstacle avoidance in complex environments. At the same time, the robot can also perform intelligent operations: the intelligent system software design supports the equipment monitoring center and the environmental monitoring center to realize real-time monitoring and remote control of the robot's working status. The robot in the present application can purify and disinfect the air at the same time, but it is not limited to the fact that the air purification and disinfection must be carried out at the same time. If there is a need, it is also possible to only purify or disinfect the air. The pipeline transports the disinfectant liquid in the container 31 to each spraying member 32. It can be transported by gravity, or it can be because a water pump is installed on the pipeline. For example, when the robot is parked on the ground to work, the side of the robot in contact with the ground is defined as the bottom, and the side away from the ground is defined as the top. Each spraying member 32 is installed at the bottom of the robot body 1. The height of the container 31 is higher than any spraying member 32. When the air needs to be disinfected, turn on the switch on the pipeline, and the disinfectant liquid will flow into the spraying member 32 under the action of gravity. This method saves electricity. At the same time, because the spraying member 32 is installed at the bottom of the robot, it is close to the ground, which prevents the disinfectant liquid from spraying on pedestrians, which is safer. At the same time, in this scenario, the air inlet 12 is also below the robot body 1, and the air outlet 13 is above the robot body 1.

[0030] In the present invention, the purification device 2 and the disinfection device 3 are placed in the robot body 1 at the same time. When disinfection is needed, the disinfectant liquid in the container 31 will flow into each spraying member 32, and the disinfectant liquid will be sprayed into the air through the spraying member 32. The present application can not only purify the air, but also disinfect the air, and has a wide range of applications.

[0031] Furthermore, the spraying member 32 is an atomizing sheet, which can spray the disinfectant liquid into the air in a mist form, which is more uniform. In some embodiments, the number of the spraying members 32 is four, and the four spraying members 32 are arranged at intervals on the outside of the robot body 1. If too many spraying members 32 are arranged, it is inconvenient to install, and if too few are arranged, the spraying force and area are not enough. Setting four is just the right number. Figure 1 As shown, the four spraying members 32 can be installed at the four corners of the robot body 1, and the spraying force is strong and the area is also large.

[0032] In the technical solution of the utility model, the purification device 2 includes three filter layers 21 stacked in sequence along the direction from the air inlet 12 to the air outlet 13, the filter layer 21 close to the air inlet 12 is a preliminary filter layer 211, the filter layer 21 close to the air outlet 13 is an activated carbon filter layer 213, and the electrostatic filter layer 212 is located between the preliminary filter layer 211 and the activated carbon filter layer 213. Exemplarily, when the robot is parked on the ground to work, the side of the robot in contact with the ground is defined as the bottom, and the side away from the ground is defined as the top. Then, the three filter layers 21 are stacked in sequence from bottom to top, the bottom one is the preliminary filter layer 211, the middle one is the electrostatic filter layer 212, and the top one is the activated carbon filter layer 213. The material of the preliminary filter layer 211 is polyurethane filter cotton. The main purpose of setting the preliminary filter layer 211 is to filter large particle pollutants such as sand, mosquitoes and catkins inhaled from the outdoors; the electrostatic filter layer 212 will generate high voltage The electrostatic field filters dust particles and oil fume particles. When dust particles in the air pass through the high-voltage electric field, corona discharge occurs at the cathode and the gas is ionized. At this time, the negatively charged gas ions move toward the anode under the action of the electric field force, and collide with the dust particles during the movement, so that the dust particles are charged. The charged dust particles also move toward the anode under the action of the electric field force, and release the electrons they carry after reaching the anode. The dust particles are deposited on the anode plate. When the oil fume exhaust gas passes through this high-voltage electric field, the oil fume particles are charged in a very short time due to collision and capture of gas ions, and move toward the positive dust collecting plate under the action of the electric field force, thereby achieving the separation effect: the activated carbon filter layer 213 has a large specific surface area and rich pore structure after undergoing high-temperature activation and special pore manufacturing process. These pore structures match the molecular size of harmful gases and can be used to specifically adsorb dozens of harmful gases such as formaldehyde. Activated carbon has a wide range of functions and has seven effects: absorbing taste, detoxification, deodorization, dehumidification, mildew prevention, sterilization, and purification.

[0033] It can be understood that a support portion 4 is provided in the cavity 11, and the three filter layers 21 are all snap-connected with the support portion 4, wherein the specific structure of the snap-connection is not limited. In some embodiments, a block 214 is provided on both sides of each filter layer 21, and a slot 41 is provided on the support portion 4. The block 214 is snap-connected with the slot 41, and the filter layer 21 is conveniently and quickly replaced. In some embodiments, the support portion 4 can be a box body. If the direction perpendicular to the ground is taken as the vertical direction, the top and bottom of the box body are open, the bottom opening is connected to the air inlet 12, and the top opening is connected to the air outlet 13. The three filter layers 21 are all arranged in the box body.

[0034] It is understandable that the purification device 2 also includes a fan 22, and the fan 22 is arranged between the activated carbon filter layer 213 and the air outlet 13 to blow air toward the air outlet 13. In some technical schemes, the disinfection device 3 also includes a plurality of ultraviolet lamps 33 arranged between the activated carbon filter layer 213 and the air outlet 13 and on the robot body 1, which can kill bacteria and further purify the air. The specific number of the plurality of ultraviolet lamps 33 is not limited, for example, it can be 1, 2, 3, etc.

[0035] like Figure 1 As shown, the number of the multiple ultraviolet lamp tubes 33 on the robot body 1 is four, and the four ultraviolet lamp tubes 33 form an ultraviolet matrix. The air purification and disinfection of the present application combines the hot cathode ultraviolet lamp matrix and the Al2O3 reflective cover (a reflective layer is applied on the top layer of the ultraviolet lamp tubes 33 in the purification device 2, that is, the cavity 11) disinfection technology to kill pathogenic microorganisms in the space in all directions without dead ends. At the same time, the atomizer sheet atomizes the disinfectant into micron-sized particles, achieving comprehensive coverage disinfection.

[0036] It is understandable that an air pump is provided between the air inlet 12 and the preliminary filter layer 211 for drawing external air from the air inlet 12 into the cavity 11 .

[0037] During use, when the air needs to be purified and disinfected, the robot is controlled to start the purification device 2 and the disinfection device 3, and the disinfectant in the container 31 flows into each spraying piece 32 through the pipeline for spraying. At the same time, air enters the cavity 11 from the air inlet 12, and passes through the three filter layers 21 in turn, and is guided by the fan 22 to reach the outside from the air outlet 13. At the same time, the robot body 1 and the ultraviolet lamp 33 in the cavity 11 also play a sterilization role.

[0038] The above description is only a preferred embodiment of the present invention and is 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.
