[0002] Service robots are a young member of the robot family and there is no strict definition yet. Different countries have different understandings of service robots. They can be divided into professional service robots and personal / family service robots. Service robots have a wide range of applications and are mainly engaged in maintenance, repair, transportation, cleaning, security, rescue, monitoring and other tasks.

[0003] The air filtration system in a service robot generally refers to a system used to filter pollutants and particulate matter from the air inside the robot. Robots usually come into contact with the environment through movement, operation, and interaction, which may cause dust, bacteria, pollen, and other pollutants in the air to enter the robot. The main function of the air filtration system is to remove pollutants from the air inside the robot through filters, thereby purifying the air and providing a cleaner and healthier working environment. This helps prevent contamination of the robot's internal components, reduce the robot's failure rate, and improve the robot's work efficiency.

[0004] HEPA is a highly efficient filter material commonly used in air filters. In the air outlet filtration system of a service robot, HEPA filter material can be used to filter pollutants and particulate matter from the air inside the robot. By installing HEPA filters at the air outlet of a service robot, the air inside the robot can be effectively purified, providing a healthier and cleaner working environment. This helps protect the robot's internal components from contamination and damage, extends the robot's service life, and improves the robot's safety in public places.

[0050] See also Figures 1 to 10 The present invention provides a quick-disassembly and replacement air outlet filter system, comprising:

[0051] like Figure 1 and Figure 5As shown, a Hypa component 1 for filtering gas is used to filter dust and debris in the gas when the gas passes through the Hypa component 1. The Hypa component 1 includes a Hypa frame 101, which is a rectangular frame. A Hypa filter paper 102 is installed in the Hypa frame 101. The Hypa frame 101 is used to fix the Hypa filter paper 102, so that the Hypa filter paper 102 can filter the air. The Hypa component 1 is not integrated. When replacing, the Hypa component 1 is taken out, and the Hypa filter paper 102 therein is replaced separately, which effectively reduces the replacement cost. A Hypa sealing strip 103 is provided on the outside of the Hypa frame 101. The Hypa sealing strip 103 is made of rubber material and has good elasticity and sealing. The Hypa sealing strip 103 is used to strengthen the sealing of the Hypa component 1 after installation to prevent air from overflowing, thereby preventing dust from remaining in the gap. A handle 104 is also fixedly connected to one side of the Hypa frame 101. The handle 104 is arranged in an arc shape, so that it is convenient to put a finger therein to pull it. The arrangement of the handle 104 facilitates pulling the Hypa frame 101 to remove the Hypa component 1. Both sides of the Hypa frame 101 are provided with inclined surfaces 1011. The inclined surface 1011 is located at a higher position near one end of the handle 104. The arrangement of the inclined surface 1011 facilitates the positioning of the Hypa component 1 during installation, so that the installation position is accurate. The bottom of the Hypa frame 101 is arranged as a bottom surface 1012. The bottom surface 1012 is provided with an opening to facilitate the circulation of air. The circulating air will pass through the Hypa filter paper 102, and the dust and debris in the air will be filtered, so that the air is purified.

[0052] like Figure 1 and Fig.10As shown, a Hypa support 3 is used to place the Hypa component 1. The Hypa support 3 is connected to the air outlet system for filtering, and the Hypa component 1 is installed in the Hypa support 3. The Hypa support 3 includes a Hypa support body 301. The Hypa support body 301 is provided with an inclined surface corresponding to the bottom surface 1012 of the Hypa component 1, so that the Hypa component 1 is installed as a whole at an angle after installation. A cylindrical pin 302 is installed in the middle position below the edge of the Hypa support body 301. The cylindrical pin 302 is provided with an internal thread to facilitate the installation of other components. The setting of the cylindrical pin 302 is convenient for fixing the cross plate body 201, so that the connection is a whole. A square hole 303 is opened on each side of the edge of the Hypa support body 301. The square hole 303 is opened in a rectangular shape and has rounded corners, which reduces wear and is more beautiful. A guide block 304 is provided in the main body 301 of the Hypa support. The guide block 304 is tilted and fixedly installed in the main body 301 of the Hypa support. The guide block 304 cooperates with the inclined surface 1011 to facilitate the installation of the Hypa component 1. Multiple sets of fixing columns 305 are installed on the outside of the main body 301 of the Hypa support for fixing the Hypa support 3, so that the whole can be installed on the air outlet system of the robot by bolts, and it is convenient to use tools to disassemble and maintain it. Multiple sets of ventilation holes 306 are provided in the main body 301 of the Hypa support for air circulation, and the air is filtered clean by the Hypa filter paper 102 when it is discharged.

[0053] like Figure 7 and Figure 8As shown, a Hypa locking rod 2 is used to fix the Hypa component 1 on the Hypa support 3. The Hypa locking rod 2 is installed on the Hypa support 3. The Hypa locking rod 2 is used to limit the Hypa component 1 after it is installed. The Hypa locking rod 2 includes a horizontal plate body 201. The horizontal plate body 201 is generally a rectangular plate with rounded edges. The horizontal plate body 201 is made of plastic material and has a certain elasticity. It will deform after being subjected to pressure, and return to its original state after the external force is removed due to its elasticity. There is a square protrusion 202 above each end of the horizontal plate body 201. The top of the square protrusion 202 is rounded and has a guiding function. The square protrusion 202 drives the end of the horizontal plate body 201 to move downward after being subjected to external force. A circular sleeve 203 is arranged below the middle of the horizontal plate body 201. The horizontal plate body 201 is fixedly installed by the circular sleeve 203, and is easy to disassemble and replace after damage. The circular sleeve 203 is sleeved on the outside of the cylindrical pin 302, wherein a fastening screw 4 is threadedly connected thereto. The fastening screw 4 is used to fix the circular sleeve 203 on the outside of the cylindrical pin 302 after installation. After installation using the fastening screw 4, the circular sleeve 203 can be removed from the cylindrical pin 302. The removal and installation are simple, and it is convenient to replace the horizontal plate body 201 after it is damaged. A groove 204 is provided on both sides of the circular sleeve 203 below the horizontal plate body 201, so that when the horizontal plate body 201 is deformed, it can be deformed around the groove 204, so that the two ends of the horizontal plate body 201 bend downward without causing the horizontal plate body 201 to break. The square protrusion 202 is slidably arranged in the square hole 303, and the square protrusion 202 protrudes from the upper surface of the edge of the main body 301 of the Hypa support, so that the Hypa component 1 will contact the square protrusion 202 during installation, thereby squeezing the square protrusion 202 downward, and the square protrusion 202 will limit the Hypa component 1 after it is reset to prevent the Hypa component 1 from falling off. The horizontal plate body 201 is inclined, and the side of the horizontal plate body 201 close to the Hypa component 1 is lower, so that the Hypa component 1 can be slidably installed in the Hypa support 3.

[0054] Working principle:

[0055] First, place the bottom surface 1012 of the Hypa component 1 on the inclined surface of the Hypa support body 301, and push it toward the direction close to the Hypa support body 301. The bottom surface 1012 of the Hypa frame 101 will contact the square protrusion 202 on the Hypa locking rod 2. Continue to push. At this time, due to the rounded corner setting of the square protrusion 202, the square protrusion 202 will be squeezed, so that the square protrusion 202 slides downward in the square hole 303. Since the cross plate body 201 is elastic, the two ends of the cross plate body 201 will elastically deform downward around the groove 204. At this time, the top of the square protrusion 202 slides and contacts the bottom surface 1012. Continue to push, and at this time, it is guided in by the inclined surface 1011 and the guide block 304 until the Hypa component 1 completely enters the Hypa support body 301. At this time, the entire Hypa component 1 passes over the square protrusion 202, and the horizontal plate body 201 will naturally rebound and reset due to its own elastic force. At the same time, the square protrusion 202 will be stuck behind the Hypa component 1, so that the installation of the Hypa component 1 is firm. Then use bolts to fix the Hypa support body 301 to the ventilation system on the robot. After the robot is started, it inhales air, and the air will inevitably be filtered through the Hypa filter paper 102, so that the filtered air does not contain dust and debris, effectively cleaning the environment. At the same time, due to the setting of the Hypa sealing strip 103, the air will not leak from the gap at the connection, so that dust will not remain in the gap, so that the connection remains clean.

[0056] When the Hepa filter paper 102 in the Hepa component 1 needs to be replaced, the position of the handle 104 is pulled by hand so that the handle 104 moves away from the Hepa support 3, and the Hepa component 1 can be pulled out of the Hepa lock rod 2. At this time, the bottom surface 1012 of the Hepa component 1 will hit the square protrusion 202. Pull out the Hepa component 1 with force. Since the upper surface of the square protrusion 202 has rounded corners, it can play a guiding role, forcing the square protrusion 202 to press down again. The two ends of the cross plate body 201 are elastically deformed downward around the groove 204, and the square protrusion 202 moves to the square hole 303, so that the Hepa component 1 can pass through the square protrusion 202 position, so that the Hepa component 1 can be smoothly separated from the Hepa support 3. Finally, the Hepa filter paper 102 in the Hepa component 1 can be directly replaced, avoiding the replacement of the Hepa component 1 as a whole, and effectively reducing the cost of replacement. Without using traditional elastic elements such as springs, the elastic deformation of the plastic parts themselves is used to simplify the structural design, make the operation more convenient, and realize the rapid replacement of Hepa.
