DETAILED DESCRIPTION

[0028] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0029] See also Figure 1 In the present embodiment, a self-locking dust box for an intelligent cleaning device comprises a dust box support 1, which is mounted on the bottom of the intelligent cleaning device (such as an intelligent sweeping robot) and assembled with the dust box body 2 to realize the rapid installation and disassembly of the dust box body 2; the dust box body 2 is detachably fixed on the dust box support 1 to collect and store garbage, and when the garbage collection reaches a certain level, it can be easily and quickly removed from the dust box support 1 to clean up the garbage. At the same time, when replacing the scraping strip 22, there is no need to turn over the entire intelligent cleaning device. It is only necessary to remove the dust box body 2 and replace the scraping strip 22 separately, which is easy to operate. The dust box body 2 and the dust box support 1 are both made of plastic.

[0030] Figure 2The structure diagram of the dust box support 1 of the present embodiment is shown. The two sides of the dust box support 1 form side panels 11 that are perpendicular to the top surface and extend downward. The two side panels 11 and the top surface of the dust box support 1 are enclosed together to form a mounting groove 14 for the dust box body 2 to be installed. A sealing strip is pasted on the edge of the top surface. When the dust box body 2 is installed in the mounting groove 14, the upper opening of the dust box body 2 is sealed with the top surface of the dust box support 1 through the sealing strip to prevent the negative pressure in the dust box body 2 from leaking. The top surface of the dust box support 1 is provided with a negative pressure port 16, which is used to connect a negative pressure fan. When the dust box body 2 is assembled on the dust box support 1, the negative pressure fan can generate negative pressure in the dust box body 2, so that the external dirt is sucked into the box to achieve a cleaning effect.

[0031] The dust box body 2 is detachably fixed in the mounting groove 14 of the dust box support 1 by side sliding. In order to realize directional sliding, guide grooves 12 are provided on the inner walls of the side plates 11 on both sides of the dust box support 1. The rear end of the guide groove 12 is open and extends from the back to the front to form a triangular structure of the guide groove 12. Guide convex strips 211 with the same shape as the guide groove 12 and capable of fitting with each other are provided on both sides of the dust box body 2. When the dust box body 2 is installed, the front end of the guide convex strip 211 is aligned with the rear end opening position of the guide groove 12, and a forward force is applied to gradually buckle the dust box body 2 into the guide groove 12 along the inner wall of the guide groove 12, so as to realize the side sliding installation of the dust box body 2.

[0032] Figure 3 , 4 5 are schematic diagrams of the structure of the dust box body 2 from different angles. In the present embodiment, the dust box body 2 is a long strip box body, and the dust box body 2 has a box slot 28 with a top opening. The sucked dirt is stored in the box slot 28. A dust suction port 27 connected to the box slot 28 is provided on the front side wall 21 of the dust box body 2. When the garbage dust box body 2 is assembled at the bottom of the dust box support 1, the negative pressure port 16 of the dust box support 1, the box slot 28 and the dust suction port 27 are connected to each other, so that external dirt enters the box slot 28 through the dust suction port 27, and is filtered by a filtering device (not shown in the figure) and collected in the box slot 28.

[0033] The guide ridges 211 are fixedly mounted on the outside of the side walls 21 on both sides of the dust box body 2. The shape of the guide ridges 211 is consistent with the shape of the guide grooves 12 on the side panels 11 on both sides of the dust box support 1 and cooperates with each other. When the dust box body 2 is assembled in a side-sliding manner, the outer end surfaces of the side walls 21 of the dust box body 2 are close to the inner end surfaces of the side panels 11 of the dust box support 1, and the front ends of the guide ridges 211 enter through the rear end openings of the guide grooves 12. Under the action of external force, the dust box body 2 is pushed forward so that the dust box body 2 is positioned in the mounting groove 14 of the dust box support 1.

[0034] The two sides of the bottom of the dust box body 2 are recessed upward to form wheel grooves 231. The running wheels 23 are rotatably arranged in the wheel grooves 231 on both sides of the dust box body 2. When the dust box body 2 is in the assembled state, the running wheels 23 are in rolling contact with the ground. During the cleaning process of the intelligent cleaning device, the running wheels 23 often cannot work normally due to entanglement with filaments such as hair, and need to be disassembled for inspection or replacement. In this way, the running wheels 23 and the dust box body 2 form an integrated structure. When the dust box body 2 is disassembled, the running wheels 23 can be disassembled together, which is convenient for disassembly and replacement of the running wheels 23.

[0035] The scraping strip 22 is made of rubber and has certain deformation ability and wear resistance. The scraping strip 22 is obliquely arranged at the lower edge of the front end of the dust box body 2, and is used to scrape away the dirt on the ground when the dust box body 2 moves forward with the intelligent cleaning device. The scraped dirt enters the dust suction port 27 along the inclined surface of the scraping strip 22 and is sucked into the box groove 28.

[0036] See also Figure 5 and Figure 6 An oblique slot 221 for inserting the scraper strip 22 is provided at the lower edge of the front end of the dust box body 2. The oblique slot 221 extends along the length direction of the dust box body 2 and has an opening at its bottom. The scraper strip pressing plate 222 is fixed to the bottom opening of the oblique slot 221 by bolts. When the scraper strip pressing plate 222 is fixed to the dust box body 2, the scraper strip 22 is positioned between the scraper strip pressing plate 222 and the dust box body 2. A part of the scraper strip 22 is obliquely inserted into the oblique slot 221, and the other part thereof extends obliquely downward to the outside of the oblique slot 221 and is pressed and fixed by the scraper strip pressing plate 222. When the scraper strip 22 needs to be disassembled and replaced, first quickly remove the dust box body 2 from the dust box support 1, and directly pull the dust box body 2 from the front to the back along the guide groove 12. After cleaning the dirt in the box groove 28 of the dust box body 2, turn it over, unscrew the fixing bolts (not shown in the figure) between the scraper strip pressing plate 222 and the dust box body 2, remove the scraper strip pressing plate 222, and finally take the scraper strip 22 out of the oblique slot 221. During installation, the installation can be completed by performing the reverse process of the above disassembly process, which will not be described here.

[0037] A locking structure is provided between the dust box body 2 and the dust box support 1, which can lock the dust box body 2 in the mounting groove 14 of the dust box support 1. When the dust box body 2 needs to be removed, the locking structure can release the dust box body 2. The dust box body 2 is locked and fixed and released for disassembly under the action of the locking structure to achieve the purpose of quick disassembly.

[0038] Combination Figure 4 and Figure 7 , Figure 4FIG. 2 is a schematic diagram showing the assembly of the locking structure and the dust box body 2. Figure 7 A schematic diagram of the mating state of the locking structure is shown. The locking structure is arranged on the rear side of the dust box body 2 (i.e., the side away from the scraper strip 22), and includes a sliding cover 24 and two locking rods 25a, 25b. The sliding cover 24 is slidably arranged at the middle position of the rear end of the dust box support 1, and a spring 243 is arranged between the two. The spring 243 applies an upward extrusion force to the sliding cover 24, so that in a normal state, the sliding cover 24 is squeezed and lifted upward. A second latch 241 is arranged at the top of the sliding cover 24, and correspondingly, a second locking hole 15 is opened at the top of the mounting groove 14 on the dust box support 1. In the locked state, the spring 243 lifts the sliding cover 24 upward and allows the second latch 241 to be inserted into the second locking hole 15. The locking rods 25a and 25b are located on both sides of the sliding cover 24 and are respectively slidably arranged on the dust box body 2 laterally. The outer ends of the two locking rods 25a and 25b (i.e., the ends away from the sliding cover 24) have first latches 25a1 and 25b1. Correspondingly, a first locking hole 13 is opened on the side plate 11 of the dust box support 1. When the locking rods 25a and 25b are displaced outward, the first latches 25a1 and 25b1 can be inserted into the first locking hole 13. When the locking rods 25a and 25b are displaced inward, the first latches 25a1 and 25b1 are separated by the first locking hole 13. The inner ends of the two locking rods 25a, 25b (i.e., the side close to the sliding cover 24) extend into the sliding cover 24 and always abut against the guide slope 242 at the inner end of the sliding cover 24. The guide slope 242 tilts outward from top to bottom and realizes the linkage between the sliding cover 24 and the locking rods 25a, 25b. At the same time, the force of the spring 243 is transmitted to the position of the locking rods 25a, 25b. The linkage operation is specifically as follows: in the locked state, the sliding cover 24 is located in the upward position under the squeezing action of the spring 243, and the inner ends of the locking rods 25a and 25b abut against the lower ends of the guiding inclined surfaces 242, that is, the locking rods 25a and 25b are located at the outer maximum position. When the dust box body 2 and the dust box support 1 are in the assembled state, the second latch 241 at the top of the sliding cover 24 is inserted into the second locking hole 15 at the top of the mounting groove 14 of the dust box support 1, and the first latches 25a1 and 25b1 at the outer ends of the locking rods 25a and 25b are inserted into the first latches 25a1 and 25b1 inside the side plates 11 on both sides of the dust box support 1. When unlocking, a thrust is applied to the two locking rods 25a, 25b toward the sliding cover 24, and the locking rods 25a, 25b slide inward to the minimum lateral position, and their inner ends follow the upper end of the guide slope 242, and push the sliding cover 24 downward under the action of the guide slope 242, and the spring 243 is compressed. At this time, the first latch 25a1, 25b1 is separated from the first locking hole 13, and the second latch 241 is separated from the second locking hole 15, thereby releasing the dust box body 2, and then the dust box body 2 can be pulled out from the dust box support 1 from front to back.

[0039] Recombination Figure 4 In this embodiment, two mounting grooves are provided on the rear end surface of the dust box support 1, and the lock rods 25a and 25b are respectively slidably arranged in the mounting grooves. A baffle plate 26 is provided at the front end of the mounting groove, and an extension hole 261 is provided on the baffle plate 26. The paddles 25a3 and 25b3 fixed on the lock rods 25a and 25b extend outwards from the extension holes 261 on the two baffle plates 26. When unlocking is required, fingers are buckled on the two paddles 25a3 and 25b3 and an inward thrust is applied, thereby driving the two lock rods 25a and 25b to slide toward each other to achieve unlocking.

[0040] The middle section of the locking rods 25a, 25b is provided with transversely extending strip guide grooves 25a2, 25b212, and limiting columns (not shown) are fixed on the inner walls of the mounting grooves. The limiting columns are positioned in the strip guide grooves 25a2, 25b212, thereby limiting the transverse sliding range of the locking rods 25a, 25b and improving the sliding stability.
