a controller (not shown) electrically connected to the non-contact inductive switch assembly 40;

when the dust bag assembly 20 is installed in the housing 10 and the cover 30 is covered on the housing 10, the contactless trigger 50 can move to a position close to the contactless inductive switch assembly 40 with the cover 30, so that the contactless inductive switch assembly 40 generates a trigger signal;

when the dust bag assembly 20 is detached from the housing 10 or/and the cover 30 is opened with respect to the housing 10, the non-contact inductive switch assembly 40 does not generate a trigger signal;

the controller limits the dust collecting device 200 to start dust collecting operation when the non-contact inductive switch assembly 40 does not generate the trigger signal.

Firstly, when the dust collecting device collects dust, the inserting plate of the dust bag component is inserted into the inserting groove in the shell, and the cover body covers the box body, at the moment, impurities such as dust and the like can be introduced into the dust bag component through the dust inlet channel under the vacuum negative pressure of the dust exhaust fan; when the dust collecting device stops collecting dust, the operator can open the cover to take the dust bag assembly out of the shell, and can put the new dust bag assembly back into the box to wait for the dust collecting device to work.

In this embodiment, the dust bag assembly includes a bag body and an insert plate connected to the bag body. The inserting plate is provided with an opening communicated with the inside of the bag body. When the inserting plate of the dust bag component is inserted into the inserting groove in the shell, the opening is in butt joint with the port of the dust inlet channel, so that the dust inlet channel is communicated with the dust bag component. The bag body is a filter bag, when the dust extraction fan works, the dust inlet channel can introduce airflow into the bag body under the action of vacuum negative pressure, and then the airflow can penetrate through the bag body and enter the exhaust channel to be exhausted, wherein the bag body can play a role in filtering to intercept dust and debris carried in the airflow. The bag body can be made of plastic or paper or composite materials, and is not particularly limited, and can be set by a person skilled in the art according to actual needs.

In this embodiment, the controller is electrically connected to the inductive switch assembly, the controller limits the dust collecting device to perform dust collecting operation according to the non-triggered state of the inductive switch assembly, and the controller releases the limitation on the dust collecting device to start the dust collecting operation according to the triggered state of the inductive switch assembly.

Therefore, before the dust collecting device performs dust collecting action, the non-contact sensing switch assembly is used for detecting whether the dust bag assembly is in place (namely whether the inserting plate of the dust bag assembly is inserted into the slot in the shell) and whether the cover body covers the shell, the detection result is fed back to the controller, and the controller limits or relieves the limitation on the work of the dust collecting device, so that the double detection function of a single sensor can be realized, the number of the sensors is favorably saved, the cost is reduced, the structure is simple, and the use reliability is high.

The mode of mechanical touch is replaced by the mode of non-contact induction control, so that the resistance when the cover body 30 is closed is eliminated, the phenomenon that dust blocks a mechanical structure to move can be avoided, the situation that the cover body 30 is difficult to close can be avoided, holes and grooves in the shell body 10 and the cover body 30 are reduced, and the appearance integrity of a product is better.

Referring to fig. 3, in the present embodiment, the housing 10 is a main body of the dust collecting device 200, and the housing 10 is provided with a dust collecting opening 12, a dust inlet passage 13, an inner cavity, and an exhaust passage 14. The dust collecting port 12 is disposed at an outer side of the housing 10, and the dust collecting port 12 is used for being abutted to a dust discharging port of the cleaning robot 100. The inner cavity is used for accommodating the dust bag assembly 30, the inner cavity has an open end, and the dust bag assembly 30 is detachably mounted in the inner cavity of the housing 10 through the open end. The cover 20 is rotatably connected to the housing 10 to close or open the open end of the inner cavity. One end of the dust inlet channel 13 is communicated with the dust collecting opening 12, and the other end is communicated with the inner cavity. One end of the exhaust channel 14 is communicated with the dust collection cavity, and the other end is communicated with the atmosphere. The dust bag assembly 30 is mounted in the dust chamber and is in communication with the dust inlet passage 13 and the air outlet passage 14. The dust exhaust fan 15 is located in the exhaust passage 14, the dust exhaust fan 15 is used for driving air to flow, and the dust exhaust fan 15 can drive the air in the inner cavity to flow to the exhaust passage 14 to be exhausted to the outside, so as to generate negative pressure in the dust bag assembly 30 and the dust inlet passage 13, so as to suck the garbage in the cleaning robot 100 into the dust bag assembly 30 under the action of the negative pressure, thereby realizing dust collection.

In one embodiment, the non-contact sensing switch assembly 40 includes a movable mechanism 42, a blocking member 44 and a non-contact sensing switch 46, one of the blocking member 44 and the non-contact sensing switch 46 is fixedly connected to the movable mechanism 42, and the other of the blocking member 44 and the non-contact sensing switch 46 is fixedly connected to the housing 10, so that the movable mechanism 42 can move one of the blocking member 44 and the non-contact sensing switch 46 relative to the housing 10;

when the dust bag assembly 20 is installed in the housing 10 and the cover 30 is closed on the housing 10, the blocking member 44 is in a position not blocking the contactless trigger 50 and the contactless sensor switch 46, so as to allow the contactless sensor switch assembly 40 to generate a trigger signal;

when the dust bag assembly 20 is detached from the housing 10 and the cover 30 is closed on the housing 10, the blocking member 44 is located at a position between the non-contact activating member 50 and the non-contact switch 46 to prevent the non-contact switch assembly 40 from generating an activating signal.

When the dust bag assembly 20 is installed in the housing 10 and the cover 30 is not covered on the housing 10, the distance between the contactless trigger 50 and the contactless sensor switch 46 is too far, and the contactless trigger 50 does not trigger the contactless sensor switch 46 to generate a trigger signal.

Specifically, in one embodiment, the non-contact inductive switch 46 is a hall switch, and the non-contact trigger 50 is a magnetic element. The non-contact type inductive switch 46 may be an infrared inductive switch, and the non-contact type triggering member 50 may trigger the infrared inductive switch. In the present embodiment, the non-contact inductive switch 46 is a hall switch, the non-contact trigger 50 is a magnetic member, and the blocking member 44 is a magnetic shielding sheet. When the dust bag assembly 20 is installed in the housing 10 and the cover 30 is covered on the housing 10, the movable mechanism 42 drives the blocking member 44 or the non-contact inductive switch 46 to move, and when the blocking member 44 is located at a position where the non-contact trigger 50 and the non-contact inductive switch 46 are not blocked, the non-contact inductive switch assembly 40 can generate a trigger signal, and the controller controls the dust bag assembly 20 to operate. For example, the output voltage of the hall switch changes due to the influence of the intensity of the magnetic field. Under normal conditions, when the Hall switch is not influenced by a magnetic field with enough strength, the output voltage is 3.3V, otherwise, 0V is output; the movable mechanism 42 of the present embodiment determines whether to move the blocking member 44 according to whether the dust bag assembly 20 is inserted and whether the cover 30 is closed, so as to correlate the change of the hall switch voltage, thereby controlling whether the dust bag assembly 20 can enter the working state.

In one embodiment, the movable mechanism 42 is movably connected to the housing 10, and the dust bag assembly 20 is mounted in the housing 10 to push the movable mechanism 42 to a first position, such that the blocking member 44 is disposed in a staggered manner with respect to the non-contact sensor switch 46;

the dust bag assembly 20 is detached from the housing 10 and pushed back to allow the movable mechanism 42 to automatically return to the second position under the action of the elastic element 424, so that the blocking member 44 blocks the non-contact sensor switch 46. The movable mechanism 42 is in the first position or the second position, respectively, depending on whether the dirt bag assembly 20 is mounted within the housing 10.

Referring to fig. 4 to 6, in an embodiment, a slot 12 is disposed in the housing 10, the movable mechanism 42 is provided with a force-receiving portion 426, and when the movable mechanism 42 is located at the second position, the force-receiving portion 426 at least partially extends into the slot 12; the dust bag assembly 20 is provided with an insertion plate 22, and the insertion plate 22 is movably inserted into the insertion slot 12 to push the movable mechanism 42 to integrally move to the first position through the force-receiving portion 426. When the dust bag assembly 20 is installed in the housing 10, the inserting plate 22 is inserted into the inserting slot 12, and in the process of inserting the inserting plate 22 into the inserting slot 12, the force-receiving portion 426 can be pushed to move, so that the movable mechanism 42 moves from the second position to the first position, when the movable mechanism 42 is located at the first position, the blocking member 44 and the non-contact inductive switch 46 are arranged in a staggered manner, when the cover 30 is also covered on the housing 10, the blocking member 44 cannot block the non-contact trigger 50 and the non-contact inductive switch 46, and the non-contact inductive switch 46 can generate a trigger signal. When the dust bag assembly 20 is not mounted in the housing 10, the movable mechanism 42 is in the second position, and the non-contact sensor switch 46 does not generate a trigger signal regardless of whether the cover 30 is closed on the housing 10. At this time, the force-receiving portion 426 extends at least partially into the slot 12, and if the dust bag assembly 20 is installed in the housing 10, the inserting plate 22 can push the portion of the force-receiving portion 426 located in the slot 12 to move the movable mechanism 42. The dust bag assembly 20 triggers the stress part 426 through the inserting plate 22, finally, the non-contact inductive switch 46 is controlled to send out a trigger signal, an additional control structure is not needed, automatic control can be performed according to whether the dust bag assembly 20 is installed, the covering resistance of the cover body 30 is not increased, the cover body 30 and the shell body 10 are not difficult to close, the inserting plate 22 and the stress part 426 are not influenced by accumulated dust, and the trigger function is stable and reliable.

The first cavity 14 and the second cavity 16 are separated by the isolation bracket 146, so that the dust bag assembly 20 and the non-contact inductive switch assembly 40 can be independent of each other without mutual interference and errors can be avoided. Specifically, the force-receiving portion 426 is a wedge-shaped block, a portion of which passes through the opening 1462, such that when the dirt bag assembly 20 is loaded into the first cavity 14, the dirt bag assembly 20 presses against the wedge-shaped block, such that the wedge-shaped block moves from the opening 1462 toward the second cavity 16, thereby moving the movable mechanism 42 from the second position to the first position.

In one embodiment, the opening 1462 is hidden inside the slot 12, and the opening 1462 is more hidden, so as to prevent the dust bag assembly 20 and the insert board 22 from wearing, but the force-receiving portion 426 is located in the opening 1462, so that the triggering function of the insert board 22 on the force-receiving portion 426 is not affected.

When the dust bag assembly 20 is not installed in the first cavity 14 of the housing 10, the movable bracket 422 is in the second position under the elastic force of the elastic member 424, and when the dust bag assembly 20 is installed in the first cavity 14 of the housing 10, the board 22 of the dust bag assembly 20 can push the force-receiving portion 426, so that the movable bracket 422 compresses the elastic member 424, and the movable bracket 422 is located in the first position, wherein the load-receiving portion 428 is used for installing the blocking member 44 or the non-contact type inductive switch 46. The resilient member 424 serves to reposition and position the movable support 422 in the second position, eliminating the need for manual manipulation and facilitating manipulation control. Specifically, the elastic element 424 is a spring, which is abutted between the movable support 422 and the side wall of the second cavity 16, and further, one end of the spring is fixed on the side wall of the second cavity 16 close to the first cavity 14, and the other end of the spring is connected to the movable support 422.

Referring to fig. 6 to 10, in an embodiment, the housing 10 is provided with two opposite slots 12 and a positioning surface 122 located between the two slots 12, the inserting plate 22 is attached to the positioning surface 122 when being inserted into and matched with the two slots 12, and the moving track of the movable support 422 is parallel to the positioning surface 122.

Referring to fig. 6 to 10, in an embodiment, the slot 12 has an open notch 124, the board 22 is inserted into the slot 12 through the notch 124, the force-receiving portion 426 has a force-receiving surface 4262 facing a side of the notch 124, the force-receiving surface 4262 is disposed obliquely with respect to a lateral moving direction of the moving mechanism 42, and the board 22 pushes the moving mechanism 42 to move laterally through the force-receiving surface 4262. The notch 124 has a guiding function, and the inserting plate 22 can quickly and accurately enter the slot 12 through the notch 124. The inclined force-bearing surface 4262 ensures that the force-bearing part 426 is pushed by the insert plate 22 when the insert plate 22 is in contact with the force-bearing surface 4262, wherein the inclined force-bearing surface 4262 also has a cushioning effect and avoids an excessive impact when the insert plate 22 is in contact with the force-bearing part 426. Specifically, when the force-receiving portion is a wedge, the force-receiving surface 4262 is an inclined surface on the wedge.

Referring to fig. 6 to 10, in an embodiment, the housing 10 has a top surface 18, the top surface 18 is disposed adjacent to the cover 30, the non-contact inductive switch 46 is fixedly connected to the housing 10 and located on a side of the top surface 18 away from the cover 30, a gap is disposed between the non-contact inductive switch 46 and the top surface 18, the blocking member 44 is fixedly connected to the movable bracket 422, and when the blocking member 44 moves to the gap along with the movement of the movable mechanism 42, the blocking member 44 blocks the non-contact inductive switch 46. By providing a gap, it is ensured that no interference or interference occurs when barrier 44 moves between proximity sensitive switch 46 and proximity trigger 50. When the cover 30 is covered on the housing 10, the cover 30 does not affect or damage the contactless sensor switch 46 and the contactless trigger 50.

The non-contact trigger 50 may also be fixedly connected to the movable support 422, and the non-contact inductive switch 46 may be mounted on the cover 30, so as to achieve the same function, and facilitate maintenance and use in various application scenarios.

If the distance between the non-contact inductive switch 46 and the non-contact trigger 50 is too far, the non-contact trigger 50 is not easy to trigger the non-contact inductive switch 46 and not easy to generate a trigger signal; if proximity between proximity sensitive switch 46 and proximity trigger 50 is too close, barrier 44 may fail or cause interference or interference with barrier 44. Therefore, in an embodiment, when the cover 30 is covered on the housing 10, the distance between the non-contact inductive switch 46 and the non-contact trigger 50 is 5mm to 30mm, and when the distance between the non-contact inductive switch 46 and the non-contact trigger 50 is 15mm, the sensing effect is the best, and no interference or interference occurs.

Fig. 2 is a state view of the dust collection device 200 when the dust bag assembly 20 is placed in the first cavity 14 of the housing 10.

When the dust bag assembly 20 is not placed in the first cavity 14 of the housing 10, but the cover 30 covers the housing 10, although the circular magnetic block is close to the hall switch, the movable support 422 is still in the second position because the movable support 422 is not triggered, at this time, the magnetic shielding sheet can isolate the magnetic field of the circular magnetic block, the hall switch is still not affected by the magnetic field of the circular magnetic block, the voltage of the hall switch is not changed, and the dust bag assembly 20 does not work. Fig. 3 is a state view of the dust collection device 200 when the dust bag assembly 20 is not placed in the first cavity 14 of the housing 10.
