Description

Technical Field

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

[0002] The core vacuuming principle of cleaning robots is based on airflow dynamics. A motor drives a fan to generate strong negative pressure, which sucks dust and debris into the machine. The robot usually uses a dust box to store the dust and debris it sucks in. The channel from the suction port to the dust box is called the air duct. However, most existing dust boxes are in a state of unobstructed connection with the air duct. When the cleaning robot sucks in live insects or other live creatures, these creatures may crawl out of the robot through the air duct and return to the room, which is quite inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a dust box structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A dustbin structure, comprising:

[0006] The device comprises a main body, a casing, a dust collection mechanism for collecting and sealing dust, and a flapping mechanism. The main body includes a storage slot with an air duct on one inner wall. The casing is located inside the storage slot, and a rectangular hole is opened on one side of the casing, which is connected to the air duct. The dust collection mechanism is located inside the casing and includes a filter bag with a rubber tube fixedly fitted to the opening. The rubber tube is movably fitted inside the rectangular hole. A U-shaped plate is fixedly connected to one side of the casing, and a plate is positioned above the U-shaped plate. A pressure plate is fixedly connected to the bottom surface of the plate, and tension springs are fixedly connected between both ends of the bottom surface of the plate and the bottom surface of the casing. The rubber tube and the pressure plate are located between the two arms of the U-shaped plate. The flapping mechanism is located inside the casing.

[0007] Furthermore, a rubber ring is fixedly sleeved at one end of the rubber tube, and a groove is provided at the outlet of the air duct, with the rubber ring movably engaged inside the groove.

[0008] Furthermore, the flapping mechanism includes:

[0009] The rotating rod and the convex plate are rotatably connected between opposite sides of the box body, and the convex plate is fixedly connected to the outer wall of the rotating rod.

[0010] Furthermore, both ends of the rotating rod penetrate the side walls of the adjacent box, and both ends of the rotating rod are fixedly connected to cams. Each of the two cams has a slot on one side. The storage slots are fixedly connected to U-shaped frames on opposite sides, and motor boxes are slidably engaged between the two arms of the two U-shaped frames. Each of the two motor boxes contains a drive motor, and the motor ends of the two drive motors are fixedly connected to clips, which are movably engaged in the adjacent slots.

[0011] Furthermore, the box body has movable slots on both sides, and L-shaped guide rods are slidably connected inside the two movable slots. The short arms of the two guide rods are respectively located above the two cams, and the long arms of the two guide rods are fixedly connected to the plate body with support rods.

[0012] Furthermore, a spring is fixedly connected between each motor box and the inner wall of the adjacent storage slot.

[0013] Furthermore, the U-shaped plate has sliding grooves on both adjacent sides of its two arms, and the pressure plate is slidably engaged between the two sliding grooves.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By starting the machine, the two drive motors start synchronously, which in turn drive the two cams and rotating rods to rotate synchronously via the clamps. This causes the two cams to rotate rapidly, moving the two guide rods upward and preventing them from descending. The guide rods then move the plate and pressure plate upward, disengaging them from the rubber tube and clearing the tube. This allows the air duct to discharge debris and dust into the filter bag. After the two drive motors stop operating, the plate and pressure plate are reset by the tension spring, pressing the rubber tube onto the U-shaped plate for sealing. This completely seals the filter bag. When the rotating rod rotates, the convex plate strikes the filter bag, redistributing the dust inside. Combined with the airflow from the air duct, this prevents dust from clogging the filter bag pores, making it easier for users to operate. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 In this embodiment of the utility model, a dust box structure includes:

[0023] The system comprises a main body 100, a housing 200, a dust collection mechanism 300 for collecting and sealing dust, and a flapping mechanism 400. The main body 100 includes a storage slot 101 with an air duct 102 on one inner wall. The housing 200 is located inside the storage slot 101, and a rectangular hole is provided on one side of the housing 200, which is connected to the air duct 102. The dust collection mechanism 300 is located inside the housing 200 and includes a filter bag 310, the opening of which is fixed. A rubber tube 311 is fitted into the rectangular hole. A U-shaped plate 210 is fixedly connected to one side of the box body 200, and a plate 320 is set above the U-shaped plate 210. A pressure plate 321 is fixedly connected to the bottom surface of the plate 320, and tension springs 322 are fixedly connected between the two ends of the bottom surface of the plate 320 and the bottom surface of the box body 200. The rubber tube 311 and the pressure plate 321 are both located between the two arms of the U-shaped plate 210. The flapping mechanism 400 is located inside the box body 200.

[0024] Specifically, the body 100 is the main body of the cleaning robot. When in use, the rubber tube 311 of the filter bag 310 is inserted into the rectangular hole and positioned between the two arms of the U-shaped plate 210. When the air duct 102 ventilates and discharges dust and debris into the filter bag 310 through the rubber tube 311, the pressure plate 321 is moved upward so that it does not contact the rubber tube 311. When the body 100 stops operating, the two tension springs 322 can automatically pull down the plate 320 together with the pressure plate 321, so that the rubber tube 311 is pressed by the pressure plate 321 against the bottom surface of the U-shaped plate 210 for sealing. The rubber tube 311 is relatively long and thin, making it easy to be pressed and sealed by the pressure plate 321, thereby reducing the problem of insects escaping from the dust box. When the filter bag 310 needs to be replaced, the filter bag 310 can be directly removed from the box 200, and then the rubber tube 311 can be manually knotted and discarded, which makes it convenient for users to clean the dust box. Example 1

[0025] like Figure 3-4 As shown, in this embodiment, a rubber ring 312 is fixedly sleeved on one end of the rubber tube 311, and a groove is provided at the outlet of the air duct 102, and the rubber ring 312 is movably engaged inside the groove.

[0026] In this embodiment, the rubber ring 312 is relatively thick. When replacing the filter bag 310, the box 200 can be taken out from the storage groove 101, and the rubber tube 311 on the new filter bag 310 can be passed through the rectangular hole. Then, the rubber ring 312 can be embedded into the groove at the outlet of the air duct 102. The box 200 can then be put back into the storage groove 101, so that the box 200 presses and fixes the rubber ring 312 in the groove, preventing the rubber ring 312 from moving.

[0027] like Figure 3-4 As shown, in this embodiment, the patting mechanism 400 includes:

[0028] The rotating rod 410 and the convex plate 420 are rotatably connected between opposite sides of the box 200. The convex plate 420 is fixedly connected to the outer wall of the rotating rod 410. Both ends of the rotating rod 410 penetrate the side wall of the adjacent box 200, and both ends of the rotating rod 410 are fixedly connected to cams 430. Each of the two cams 430 has a slot 431 on one side. U-shaped frames 440 are fixedly connected to opposite sides of the storage slot 101, and motor boxes 441 are slidably engaged between the two arms of the two U-shaped frames 440. Both motor boxes 441 are equipped with... There is a drive motor, and the motor ends of the two drive motors are fixedly connected to the clamps 442. The clamps 442 are movably engaged in the interior of the adjacent clamps 431. The box body 200 has moving slots on both sides, and L-shaped guide rods 330 are slidably connected inside the two moving slots. The short arms of the two guide rods 330 are respectively located above the two cams 430, and the long arms of the two guide rods 330 are fixedly connected to the plate body 320. A spring spring 443 is fixedly connected between any motor box 441 and the inner wall of the adjacent storage slot 101.

[0029] In practice, after inserting the rubber ring 312 into the groove at the outlet of the air duct 102, the box 200 can be placed into the storage slot 101. The two motor boxes 441 are manually turned, and then the motor boxes 441 are reset by adjacent springs 443, causing the clips 442 on the two motor boxes 441 to engage with the two slots 431 respectively. The filter bag 310 then naturally rests on the rotating rod 410. The two motor boxes 441 are connected to the internal circuitry of the machine body 100, allowing the two motor boxes 441 to start synchronously when the machine body 100 starts. This causes the two drive motors to drive the rotating rod 410 and the two cams 430 to rotate synchronously. When the rotating rod 410 rotates, it can tap the filter bag 310 through the protrusion 420, redistributing the dust inside the filter bag 310. When dust is discharged into the air duct 102, the airflow prevents the dust from clogging the filter holes on the filter bag 310. The two cams 430 rotate rapidly, causing the two L-shaped guide rods 330 to move upward. Because the cams 430 rotate quickly, the two guide rods 330 are quickly moved upward and are not easy to descend. This causes the two guide rods 330 to drive the plate 320 and the pressure plate 321 to disengage from the rubber tube 311 through the support rod, making the rubber tube 311 unobstructed and allowing the dust discharged from the air duct 102 to enter the filter bag 310. After the machine body 100 stops, the two drive motors stop rotating, causing the plate 320 and the pressure plate 321 to be pulled back by the tension spring 322 to press and seal the rubber tube 311. At the same time, the two guide rods 330 press the cams 430 downward. Example 2

[0030] Based on Embodiment 1, a sliding groove is provided to facilitate the movement of the pressure plate 321.

[0031] like Figure 4As shown, in this embodiment, the U-shaped plate 210 has a sliding groove on each of the two adjacent sides, and the pressure plate 321 is slidably engaged between the two sliding grooves.

[0032] In practice, the position of the pressure plate 321 is limited by the sliding groove, making the movement of the pressure plate 321 more stable and preventing the pressure plate 321 from tilting when it moves.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
