Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a dust box structure and a cleaning robot. Background Technology

[0002] A cleaning robot (also known as a robotic vacuum cleaner) is an intelligent home appliance that integrates automatic cleaning and vacuuming functions. It uses sensors to perceive the environment and plan its path, achieving unmanned cleaning and greatly improving the convenience of home cleaning. Most existing cleaning robots consist of a dustbin, dust bag, and HEPA filter as one component, and a suction roller brush and suction strips as another. These two components are relatively independent, with the former located at the top and the latter at the bottom, separated by a long pipe. This long pipe makes it easier for residual debris to accumulate, leading to mold and odor, and also increases the likelihood of pipe blockage. Furthermore, the machine needs to be inverted to disassemble and maintain the suction roller brush and suction strips, which is inconvenient and user-unfriendly. Utility Model Content

[0060] like Figure 1-17 As shown, this dust box structure is applied to a cleaning robot and includes a dust box assembly 2 and a dust box compartment assembly 1. The dust box compartment assembly 1 is located inside the cleaning robot body, and the dust box assembly 2 and the dust box compartment assembly 1 are detachably connected.

[0061] The dustbin assembly 1 includes a dustbin body 101, which is a semi-open cavity structure made of sheet metal. The left end of the dustbin body 101 is provided with a suction connector 102 and a roller brush drive structure 103. The outer end of the suction connector 102 is connected to the fan of the cleaning robot through a connecting hose. The roller brush drive structure 103 includes a motor, a synchronous belt pulley set, a spline shaft, etc.

[0062] The dust box assembly 2 includes a dust box body 201. Rollers 12 are provided on both the left and right sides of the bottom of the dust box body 201. The rollers 12 are used for the movement and support of the entire cleaning robot. The dust box body 201 has an overall square cavity structure. The lower ends of the front and rear side walls of the dust box body 101 are respectively bent with flanges 104 that are adapted to the shape of the dust box body 201. The dust box body 201 is set in the dust box body 101 through the two flanges 104. The two flanges 104 can both support the dust box body 201 and serve as guide rails to facilitate the insertion and removal of the dust box body 201.

[0063] A latching assembly 8 is provided between the dust box body 201 and the dust box compartment body 101 for fixing or separating the two. The dust box body 201 can be easily disassembled and assembled by locking or unlocking the latching assembly 8.

[0064] The upper end of the dust box body 201 is provided with a sealing cover 202. One end of the sealing cover 202 is connected to the dust box body 201 through a hinge structure. The sealing cover 202 seals the upper opening of the dust box body 201 by pressing and fastening.

[0065] The bottom of the dust box body 201 is provided with a dust suction port, and a dust suction roller brush 204 is provided inside the dust suction port. The dust suction roller brush 204 is preferably a V-shaped roller brush.

[0066] One end of the suction roller brush 204 is driven to the roller brush drive structure 103 via the roller brush connector 205, and the other end of the suction roller brush 204 is rotatably connected via the roller brush cover 206 with a buckle. The roller brush cover 206 is opened and closed by the buckle, realizing the disassembly and assembly of the suction roller brush 204. The roller brush connector 205 is located on the left side of the bottom of the dust box body 201. One end of the suction roller brush 204 is inserted into one end of the roller brush connector 205, and the other end of the roller brush connector 205 is engaged with the spline shaft in the roller brush drive structure 103. The motor drives the spline shaft to rotate through the synchronous belt pulley set, which in turn drives the roller brush connector 205 engaged with the spline shaft to rotate, and thus the suction roller brush 204 rotates.

[0067] The bottom of the dust box body 201 is provided with a suction strip 208 by means of a rubber strip pressure plate 207 and is located in front of the suction port. The suction strip 208 is L-shaped. The rubber strip pressure plate 207 is fixed to the bottom of the dust box body 201 by screws or other detachable means. That is, the rubber strip pressure plate 207 clamps and fixes one side of the suction strip 208 to the bottom of the dust box body 201, while the other side is perpendicular to the bottom of the dust box body 201. The suction strip 208 is a flexible structure. When cleaning, it sticks to the ground to block dust and garbage without damaging the ground. After a period of use, it will wear out. The screws can be loosened to separate the rubber strip pressure plate 207 from the bottom of the dust box body 201 so that the worn suction strip 208 can be removed and replaced.

[0068] The dust box body 201 is internally provided with a dust bag 209 and a suction bend 210. The inlet of the suction bend 210 corresponds to the suction roller brush 204. Preferably, the inlet of the suction bend 210 is located in the middle of the suction roller brush 204 in the left-right direction. The outlet of the suction bend 210 is detachably connected to one end of the dust bag 209. The other end of the dust bag 209 is sealed by a pipe clamp. Since the dust bag 209 and the suction bend 210 are detachably connected, it is convenient to remove the dust bag 209. The garbage can be emptied by opening the pipe clamp. The dust bag 209 can be reused several times. When it is worn out, a new dust bag 209 can be replaced. In addition, the dust bag 209 can collect and store garbage on the one hand, and filter on the other hand, to prevent dust and other impurities from being sucked into the fan.

[0069] HEPA filter 211 is inserted into the left side of the interior of the dust box body 201 and is in contact with the dust bag 209. That is, HEPA filter 211 is fixed by the front side wall, rear side wall, left side wall of the dust box body 201, the dust bag 209 and the sealing cover 202. When replacing HEPA filter 211, simply open the sealing cover 202 to pull out the failed HEPA filter 211 and then insert a new HEPA filter 211.

[0070] The dust box body 201 has an air outlet connector 212 on its left end, which corresponds to the HEPA filter 211. The air outlet connector 212 is sleeved on the inner end of the suction connector 102. The HEPA filter 211 further filters dust and other impurities, ensuring that dust and other impurities are not sucked into the fan. In other words, the dust bag 209 acts as the first filter of the fan, and the HEPA filter 211 acts as the second filter of the fan. Through double filtration protection, it is ensured that dust and other impurities are not sucked into the fan.

[0071] like Figure 8 , Figure 9 , Figure 11As shown in this example, in order to further improve the efficiency of the suction roller brush 204 in raising dust and debris, three rows of brush bristle plates 213 are evenly distributed along the circumferential direction on the outer side of the roller of the suction roller brush 204. The brush bristle plates 213 are V-shaped. Together with the V-shaped suction roller brush 204, they "sweep" up dust, debris and other debris from the ground and "raise" them into the airflow. Then, they are sucked into the suction bend 210 and collected by the dust bag 209. In addition, the V-shaped structure of the suction roller brush 204 and the V-shaped brush bristle plates 213 can better gather the debris in the middle of the suction roller brush 204 and prevent it from being scattered to the sides. This facilitates the collection of hair and debris by the inlet of the suction bend 210 and improves the collection efficiency.

[0072] In this example, in order to further improve the sealing performance of the sealing cover 202, a sealing gasket is provided at the edge of the sealing cover 202. The sealing gasket can effectively seal the gap between the sealing cover 202 and the dust box body 201, improve the airtightness, and further improve the dust collection efficiency of the fan. Preferably, the sealing gasket is made of silicone rubber.

[0073] like Figure 6 , Figure 7 , Figure 8 As shown, in this example, in order to further improve the sealing between the air outlet connector 212 and the air intake connector 102, a sealing element 203 is provided on the air outlet connector 212. Preferably, the sealing element 203 is made of silicone rubber. The sealing element 203 is used to seal the gap between the air outlet connector 212 and the air intake connector 102. By setting the sealing element 203, the dust collection efficiency of the fan is further improved.

[0074] In this example, preferably, the inlet end of the suction bend 210 is conical. The conical design can effectively accelerate the airflow and improve the dust carrying capacity.

[0075] like Figure 10 , Figure 12 , Figure 13 As shown, in this example, in order to facilitate the assembly and disassembly of the vacuuming bend 210 and the dust bag 209, a connecting plate 3 is provided at the outlet of the vacuuming bend 210.

[0076] The connecting plate 3 is provided with a first through hole 4 that matches the size of the outlet of the suction bend 210 and is directly corresponding to the outlet of the suction bend 210.

[0077] The front and rear sides of the connecting plate 3 are bent to form snap-fit ​​grooves 5;

[0078] One end of the dust bag 209 is provided with a snap-fit ​​plate 6 that is adapted to the slot. The snap-fit ​​plate 6 is provided with a second through hole 7, and the size of the second through hole 7 is the same as the size of the first through hole 4.

[0079] The snap-fit ​​plate 6 is inserted into the snap-fit ​​groove 5 and the second through hole 7 overlaps and communicates with the first through hole 4. The insertion and removal of the snap-fit ​​plate 6 can facilitate the quick and easy assembly and disassembly of the vacuum tube 210 and the dust bag 209.

[0080] like Figure 14-17 As shown, in this example, preferably, the snap-fit ​​assembly 8 includes a first slot 801 and a second slot 802 disposed on the right side of the front and rear side walls of the dust box body 101;

[0081] A fixing plate 803 is provided at the right end of the dust box body 201, and a separation pull ring 804 is provided on the right side of the fixing plate 803.

[0082] The separating pull ring 804 is provided with a cam rotating part 805 and is mounted on the fixed plate 803 via a rotating shaft. The fixed plate 803 is provided with a third through hole adapted to the cam rotating part 805 (not shown in the figure). A part of the cam rotating part 805 is located in the third through hole.

[0083] The right end of the dust box body 201 is provided with a storage groove, which is not shown in the figure. When the dust box body 201 is completely located inside the dust box compartment body 101, the front and rear ends of the storage groove correspond to the first slot 801 and the second slot 802 respectively. The front and rear sides of the storage groove are provided with a first card plate 808 and a second card plate 809 respectively. The first card plate 808 and the second card plate 809 have the same structure.

[0084] A pressing plate 810 is provided between the first plate 808 and the second plate 809. The pressing plate 810 is always in sliding contact with the cam rotating part 805. The pressing plate 810 is provided with two guide holes located on the front and rear sides of the cam rotating part 805.

[0085] The right end of the dust box body 201 is provided with two guide rods 811, which are located in two guide holes respectively. The cooperation between the guide holes and the guide rods 811 allows the extrusion plate 810 to move left and right in a straight line.

[0086] The first mounting plate 812 is provided at one end of the first plate 808 near the extrusion plate 810 and the two are perpendicular to each other. The first mounting plate 812 is vertically arranged on the left side of the first plate 808. A first compression spring 806 is provided between the first mounting plate 812 and the front side wall of the dust box body 201. The second mounting plate 809 is provided at one end of the second plate 809 near the extrusion plate 810 and the two are perpendicular to each other. The second mounting plate is vertically arranged on the left side of the second plate 809. A second compression spring 807 is provided between the second mounting plate and the rear side wall of the dust box body 201.

[0087] The rear end face of the first clamping plate 808 and the front end face of the pressing plate 810 are both chamfered, and their chamfered surfaces slide against each other. The front end face of the second clamping plate 809 and the rear end face of the pressing plate 810 are both chamfered, and their chamfered surfaces slide against each other. When the separating pull ring 804 rotates clockwise to be parallel to the fixed plate 803, the tip of the cam rotating part 805 abuts against the pressing plate 810. During the rotation of the cam rotating part 805, the cam rotating part 805 pushes the pressing plate 810 to move to the left along the guide rod 811, thereby pushing the first clamping plate 808 and the second clamping plate 809 to extend outward. At this time, the first compression spring 806 and the second compression spring 807 are compressed simultaneously, causing the first clamping plate 808 to extend outward. The front end of the 08 is located in the first slot 801, and the front end of the second slot 809 is located in the second slot 802 to achieve locking. When the separation pull ring 804 rotates 90 degrees clockwise, that is, when the separation pull ring 804 is perpendicular to the fixed plate 803, during the rotation of the cam rotating part 805, the tip of the cam rotating part 805 gradually disengages from the extrusion plate 810. The first compression spring 806 and the second compression spring 807 restore their deformation, push the first slot 808 and the second slot 809 to move inward and push the extrusion plate 810 to move to the right along the guide rod 811 until the first slot 808 and the second slot 809 are completely disengaged from the first slot 801 and the second slot 802, thereby unlocking and allowing the dust box body 201 to be pulled out.

[0088] In addition, a first limiting plate 9 is provided at both the upper and lower ends of the first card plate 808. The first limiting plate 9 is located on the left side of the first card plate 808 and the two are perpendicular to each other. When the front end of the first limiting plate 9 contacts the front side wall of the dust box body 201, the front end of the first card plate 808 is just inside the first card slot 801 and will not protrude to the outside of the first card slot 801. A second limiting plate 10 is provided at both the upper and lower ends of the second card plate 809. The second limiting plate 10 is located on the left side of the second card plate 809 and the two are perpendicular to each other. When the rear end of the second limiting plate 10 contacts the rear side wall of the dust box body 201, the rear end of the first card plate 808 is just inside the second card slot 802 and will not protrude to the outside of the second card slot 802. By setting the limiting plates, the excessive protrusion of the first card plate 808 or the second card plate 809 can be effectively avoided.

[0089] like Figure 8 , Figure 9 As shown in this example, preferably, the lower surface of the roller brush cover 206 is inclinedly provided with an L-shaped scraper 11 by screws. One end of the scraper 11 extends to the edge of the suction port. The scraper 11 is made of the same material as the suction strip 208. The scraper 11 can collect and guide the garbage in the area outside the suction port to the suction port, which is convenient for the suction roller brush 204 to collect, effectively increasing the cleaning area and improving cleaning efficiency.

[0090] In this example, preferably, the dust bag 209 is made of H12 meltblown material, which has a filtration efficiency of up to 99.9% (0.3μm-PFE).

[0091] In this example, preferably, the HEPA 211 is made of washable HEPA and has a filtration efficiency of over 95% (0.3μm-PFE).

[0092] This utility model also provides a cleaning robot, including the dust box structure described in any one of the above.

[0093] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
