Description

Technical Field

[0001] This utility model relates to the field of household cleaning equipment, specifically to an air-purifying sweeping robot with multiple filtration functions. Background Technology

[0002] As modern people increasingly pursue a higher quality of life, home cleaning and air purification have become key areas of focus. In today's fast-paced world, people's requirements for their living environment go beyond basic comfort, encompassing health, safety, and environmental protection. Consequently, the market demand for comprehensive household appliances that can efficiently clean floors and thoroughly purify the air is growing.

[0003] Traditional robotic vacuum cleaners are mainly used to clean dust and debris from the floor, but their functions are relatively limited and they are not effective in dealing with airborne particulate matter, allergens, bacteria, viruses, and other pollutants. On the other hand, although standalone air purifiers can improve air quality in specific areas, they are usually fixed in one location and cannot achieve whole-house air purification coverage. Therefore, we offer a robotic vacuum cleaner with multiple filtration functions. By combining the advantages of both, we hope to provide users with a more comprehensive solution for indoor environment and air quality. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, an air-purifying sweeping robot with multiple filtration functions is provided.

[0005] The technical solution is: an air-purifying robotic vacuum cleaner with multiple filtration functions, comprising a robotic vacuum cleaner body, which is the main assembly of this device and is based on existing vacuum cleaning technology; it also includes a filter frame, a pre-filter layer, a high-efficiency air filter layer, an activated carbon filter layer, an ultraviolet lamp, and an electric fan. A cavity is formed on one side of the robotic vacuum cleaner body's shell, and a filter frame is assembled within this cavity. The surface of the filter frame has densely packed filter holes, and a pre-filter layer is disposed on the inner wall of the filter frame close to the filter holes. The system includes a pre-filter layer for initial filtration of larger particles, an inner high-efficiency air filter layer for capturing fine particles, and an activated carbon filter layer for adsorbing gaseous pollutants from the air. An ultraviolet lamp is also mounted inside the filter frame via a power supply socket. A ventilation opening is located at the top of the robot vacuum cleaner's housing near the filter frame, and an electric fan is installed at this ventilation opening, with the fan's air inlet facing inwards towards the filter frame.

[0006] Furthermore, the filter frame is modularly and detachably assembled into the housing cavity of the robot vacuum cleaner body. The filter frame has a latch, and the inner wall of the housing cavity of the robot vacuum cleaner body is provided with a buckle for locking the latch of the filter frame. The buckle allows the filter frame to be easily disassembled and assembled in the housing cavity of the robot body, facilitating the maintenance and replacement of the filter components inside the filter frame.

[0007] Furthermore, the fastening component includes a wedge block, a contact plate, a support plate, and an electric push rod. A groove is provided on the shell of the robot vacuum body near the cavity. A support plate is fixedly installed within the groove of the robot vacuum body's shell. The support plate is slidably connected to the wedge block via a guide rod. A spring is provided between the support plate and the wedge block. A contact plate is fixedly installed at the end of the guide rod of the wedge block. An electric push rod is also fixedly installed within the groove of the robot vacuum body's shell. The push rod of the electric push rod contacts the contact plate on the wedge block. Under the action of the spring, the wedge block can engage with the corresponding slot on the filter frame, allowing the filter frame to be securely mounted on the robot vacuum body. The electric push rod, in conjunction with pressing the contact plate, can easily disengage from the lock on the filter frame slot.

[0008] Furthermore, the top of the body of the sweeping robot is provided with an outer shell, which is used to protect the electric fan. Air outlets are evenly spaced on the side wall of the outer shell, and each air outlet is provided with a filter screen.

[0009] Furthermore, a locking block is fixed at the bottom of the outer shell, and a slot adapted to the locking block is opened on the top shell of the robot vacuum body. The outer shell slides into the slot on the robot vacuum body shell through the locking block, so that the outer shell can be easily installed and removed from the robot vacuum body.

[0010] Furthermore, it also includes anti-slip textures. The outer casing has a ring of anti-slip textures on its side wall in the circumferential direction. The anti-slip textures increase the friction when the casing is twisted, making it easier for users to maintain the casing.

[0011] The beneficial effects are as follows: 1. By integrating a filter frame and an electric fan into the body of the sweeping robot, and in conjunction with the pre-filter layer, high-efficiency air filter layer, activated carbon filter layer and ultraviolet lamp inside the filter frame, the present invention can perform multiple filtrations on pollutants in the air drawn into the filter frame, so that the sweeping robot can efficiently purify the air while cleaning the floor.

[0012] 2. The filter frame of this utility model adopts a modular design, using a buckle composed of wedge blocks, contact plates, support plates and electric push rods to achieve stable assembly while providing a convenient unlocking method, thus enhancing the user experience.

[0013] 3. The outer shell of this utility model not only protects the electric fan, but also ensures smooth ventilation and prevents foreign objects from entering by using evenly spaced air outlets and filters. The outer shell is also easy to disassemble and maintain by the cooperation of the locking block at the bottom of the shell with the locking groove on the shell. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] A robotic vacuum cleaner with multiple filtration functions, such as Figures 1-6As shown, the device includes a robotic vacuum cleaner body 1, which serves as the main assembly of the device and utilizes existing robotic vacuum cleaning technology. It also includes a filter frame 2, a pre-filter layer 3, a high-efficiency air filter layer 4, an activated carbon filter layer 5, an ultraviolet lamp 6, and an electric fan 8. A chamber is located on one side of the robotic vacuum cleaner body 1. The filter frame 2 is installed within this chamber, and its surface has densely packed filter holes. A pre-filter layer 3 is located on the inner wall of the filter frame 2, close to the filter holes. This pre-filter layer 3 is used for initial filtration of larger particles (such as dust, hair, and fibers). An high-efficiency air filter layer 4 is located inside the pre-filter layer 3, which is used to capture fine particles (pollen, dust mites, mold spores, and bacteria). Activated carbon is located inside the high-efficiency air filter layer 4. The filter layer 5, an activated carbon filter layer 5, is used to adsorb gaseous pollutants (organic compounds, odors, and smoke, etc.) in the air. The filter frame 2 is also equipped with an ultraviolet lamp 6 through a power supply base 61. The top of the robot body 1 has a vent located at the filter frame 2. An electric fan 8 is installed at this vent. The air inlet of the electric fan 8 faces the inside of the filter frame 2. During the cleaning process, the robot body 1 draws air into the filter frame 2 through the electric fan 8, so that the bad air from the outside is continuously drawn into the filter frame 2. It is filtered in sequence by the pre-filter layer 3, the high-efficiency air filter layer 4, and the activated carbon filter layer 5, and sterilized by the ultraviolet lamp 6. The filtered fresh air is then discharged from the top of the robot body 1 by the electric fan 8. Thus, the robot body 1 can purify the air while cleaning the floor.

[0023] like Figure 2 , Figure 3 and Figure 5 As shown, the filter frame 2 is modularly and detachably assembled inside the shell cavity of the robot body 1. The frame of the filter frame 2 has a latch 7. The inner wall of the shell cavity of the robot body 1 is provided with a fastener for locking the latch 7 of the filter frame 2. The fastener allows the filter frame 2 to be easily disassembled and assembled in the shell cavity of the robot body, facilitating the maintenance and replacement of the filter components inside the filter frame 2.

[0024] like Figure 4 , Figure 5 and Figure 6As shown, the fastener includes a wedge block 9, a contact plate 91, a support plate 10, and an electric push rod 12. A groove is provided on the shell of the robot body 1 near the cavity. The support plate 10 is fixedly installed in the groove of the robot body 1. The wedge block 9 is slidably connected to the support plate 10 via a guide rod. A spring 11 is provided between the support plate 10 and the wedge block 9. The contact plate 91 is fixedly installed at the end of the guide rod of the wedge block 9. An electric push rod 12 is also fixedly installed in the groove of the robot body 1. The push rod of the electric push rod 12 contacts the contact plate 91 on the wedge block 9. Under the action of the spring 11, the wedge block 9 can be engaged into the corresponding slot 7 on the filter frame 2, so that the filter frame 2 is securely assembled onto the robot body 1. With the electric push rod 12 pressing the contact plate 91, the electric push rod 12 can easily disengage from the locking of the slot 7 on the filter frame 2.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, the top of the body shell of the sweeping robot 1 is provided with an outer shell 13, which is used to protect the electric fan 8. Air outlets are evenly spaced on the side wall of the outer shell 13, and each air outlet of the outer shell 13 is provided with a filter screen 14. A locking block 16 is fixed at the bottom of the outer shell 13, and a slot 17 adapted to the locking block 16 is opened on the top shell of the sweeping robot 1. The outer shell 13 is slidably inserted into the slot 17 on the shell of the sweeping robot 1 through the locking block 16, so that the outer shell 13 can be easily installed and removed from the sweeping robot 1.

[0026] like Figure 1 As shown, it also includes anti-slip texture 15. A ring of anti-slip texture 15 is provided around the side wall of the outer shell 13. The anti-slip texture 15 increases the friction when the outer shell 13 is twisted, making it easier for users to maintain the outer shell 13. The ultraviolet lamp 6, electric fan 8, and electric push rod 12 are all electrically connected to the battery inside the robot vacuum cleaner body 1 via the controller. The ultraviolet lamp 6, electric fan 8, and electric push rod 12 are all existing technologies, and their specific structures, working principles, and electrical connections are not detailed here.

[0027] When this air-purifying robotic vacuum cleaner is cleaning the floor, the electric fan 8 generates a negative pressure airflow at the top, drawing surrounding air into the filter frame 2 through the inlet of the housing chamber. The air first passes through the pre-filter layer 3, whose dense fiber structure can intercept large particulate pollutants such as dust and hair. The airflow then penetrates the high-efficiency air filter layer 4, which efficiently captures airborne particles, including pollen, bacteria, and other suspended particles. After physical filtration, the air continues to pass through the activated carbon filter layer 5. The porous structure of the activated carbon filter layer 5 removes formaldehyde, odors, and volatile organic compounds through chemical adsorption. Finally, the air, after multiple layers of filtration, enters the filter frame 2. At this time, the ultraviolet lamp 6 continuously purifies the air within the filtration channel. Irradiation sterilization destroys the DNA structure of microorganisms to kill residual pathogens. The purified air flows through the electric fan 8 and the honeycomb-shaped air outlet of the outer casing 13 and is evenly discharged. The filter screen 14 attached to the air outlet of the outer casing 13 can prevent external dust from entering the electric fan 8 and causing pollution. When it is necessary to remove the filter components inside the filter frame 2 for maintenance, simply activate the electric push rod 12. The push rod of the electric push rod 12 extends and presses the contact plate 91, causing the wedge block 9 to disengage from the locking of the filter frame 2's latch 7, and the filter frame 2 can be easily removed. When the filter screen 14 on the outer casing 13 needs to be cleaned, simply rotate and twist the outer casing 13 on the top of the robot body 1 to disengage the latch 16 and the slot 17 of the outer casing 13 for easy removal.

[0028] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
