The following describes a specific implementation of the present invention in more detail with reference to specific embodiments:

example one

Referring to fig. 1, 3 and 5, an embodiment of the present invention provides a dust collecting apparatus, which includes a housing 100, a dust bag assembly 200 detachably installed in the housing 100, a cover 300 capable of covering or uncovering the housing 100, and a trigger structure 400, a detection switch 500 and a controller (not shown in the drawings) all disposed in the housing 100, wherein the trigger structure 400 is movably movable between an initial position and a trigger position, the trigger structure 400 does not trigger the detection switch 500 at the initial position, and the trigger structure 400 triggers the detection switch 500 at the trigger position; when the dust bag assembly 200 is installed in the box body 100 and the box cover 300 covers the box body 100, the dust bag assembly 200 and the box cover 300 respectively push the trigger structure 400, so that the trigger structure 400 moves from an initial position to a trigger position and triggers the detection switch 500; the controller is electrically connected to the detection switch 500, and the controller restricts the operation of the dust collecting device according to the non-activated state of the detection switch 500, and releases the restriction of the operation of the dust collecting device according to the activated state of the detection switch 500.

First, when the dust collecting apparatus is operated, the dust bag assembly 200 is placed in the box 100, and the box cover 300 covers the box 100, and at this time, impurities such as dust can be introduced into the dust bag assembly 200 through the dust suction pipe 121 of the box 100; when the dust collecting device is suspended, the operator may open the cover 300 and the box 100, then take the dust bag assembly 200 out of the box 100, clean the impurities in the dust bag assembly 200, and after the cleaning is completed, put the dust bag assembly 200 back into the box 100 to wait for the dust collecting device to work.

Therefore, before the dust collecting device works, the present embodiment performs the related detection of whether the dust bag assembly 200 is in place (i.e. whether the dust bag assembly 200 is put back into the box 100) and whether the box cover 300 covers the box 100 through the trigger structure 400 and the detection switch 500, and feeds back the detection result to the controller, and the controller restricts or releases the restriction on the dust collecting device. Simple structure, performance is preferred.

Specifically, as shown in fig. 3, 4, and 5, when the dust bag assembly 200 is first placed back into the box 100 and the box cover 300 is closed over the box 100, the trigger structure 400 is pushed by the dust bag assembly 200 and the box cover 300 to move from the initial position to the trigger position, the trigger structure 400 triggers the detection switch 500 at the trigger position, the controller releases the limitation on the operation of the dust collecting device after obtaining a signal indicating that the detection switch 500 is in the trigger state, and at this time, the dust collecting device is allowed to operate or suspend as needed.

On the contrary, as shown in fig. 6, when the cover 300 is opened and/or the dust bag assembly 200 is taken out from the box 100, the trigger structure 400 cannot be pushed by the dust bag assembly 200 and the cover 300, so that the trigger position cannot be reached, and the detection switch 500 cannot be triggered, during which the detection switch 500 is in an unfired state, and the controller can continuously limit the operation of the dust collecting apparatus until the dust bag assembly 200 is put back into the box 100 and the cover 300 covers the box 100, during which the signal that the detection switch 500 is in the unfired state is obtained.

To sum up, in the dust collecting apparatus according to the embodiment of the present invention, when the box cover 300 is opened and the box 100 and/or the dust bag assembly 200 is taken out of the box 100, the detection switch 500 is in the non-triggered state, and the controller continuously limits the operation of the dust collecting apparatus while the detection switch 500 is in the non-triggered state; when the dust bag assembly 200 is first placed back into the box 100 and the box cover 300 is then closed over the box 100, the trigger structure 400 is pushed by the dust bag assembly 200 and the box cover 300, so that the trigger structure 400 moves from the initial position to the trigger position and triggers the detection switch 500, and then the controller can release the limitation on the operation of the dust collecting device after obtaining a signal that the detection switch 500 is in the trigger state, and allow the dust collecting device to operate or suspend operation as required. Therefore, the dust collecting device provided by the embodiment of the utility model can realize the relevant detection of whether the dust bag assembly 200 is in place and whether the box cover 300 covers the box body 100 through the trigger structure 400 and the detection switch 500, and then limit or release the limitation of the dust collecting device to work through the controller based on the state of the detection switch 500, so that the dust collecting device has the advantages of simple structure and high detection accuracy, and can basically avoid the situation that the dust collecting device cannot normally work due to the fact that the dust bag assembly 200 is in place but the box cover 300 is not covered, thereby having better service performance.

Alternatively, the controller may be a Microcontroller Unit (MCU), for example, the controller may be an ARM Cortex-M4-32 bit Microcontroller, which is not limited in this embodiment.

Optionally, the detection switch 500 is pressed by the trigger structure 400 to switch from the un-triggered state to the triggered state when the trigger structure 400 is in the triggered position. Specifically, when the trigger structure 400 reaches the trigger position, the trigger structure 400 may press against the detection switch 500 to switch the detection switch 500 from the non-trigger state to the trigger state; conversely, when the trigger structure 400 is moved away from the trigger position, the detection switch 500 is released from being pressed and is switched from the trigger state back to the non-trigger state. By such an arrangement, the detection switch 500 can be switched between the non-triggered state and the triggered state simply, accurately and immediately, the sensitivity of state switching of the detection switch 500 can be improved, and the detection accuracy can be further improved.

Optionally, the detection switch 500 may be a micro switch, and thus, the trigger structure 400 may switch the state of the detection switch 500 between the non-triggered state and the triggered state with a very small force, so that the state switching operation of the detection switch 500 is sensitive and immediate, thereby improving the detection accuracy and sensitivity of "whether the dust bag assembly 200 is in place" and "whether the box cover 300 covers the box body 100", and further improving the usability of the dust collecting device.

Of course, in other possible embodiments, the detection switch 500 may be toggled by the trigger structure 400 to switch from the un-triggered state to the triggered state. The detection switch 500 may be a hall sensor, a push button switch, a boat-type switch, a toggle switch, or a toggle switch, etc., which is not limited in this embodiment.

Referring to fig. 3, 4 and 5, in the present embodiment, the trigger structure 400 can move to the preparation position, the preparation position is located between the initial position and the trigger position, and the trigger structure 400 does not trigger the detection switch 500 in the preparation position; the dust bag assembly 200 is installed in the box 100 to push the trigger structure 400 to move from the initial position to the ready position, so that the cover 300 covers the box 100 to push the trigger structure 400 to continue to move from the ready position to the trigger position.

Specifically, the dust bag assembly 200 is first placed back into the box 100, at this time, the trigger structure 400 is pushed by the dust bag assembly 200 to move from the initial position to the preparation position, then the box cover 300 covers the box 100, the trigger structure 400 is pushed by the box cover 300 to move from the preparation position to the trigger position, the trigger structure 400 can trigger the detection switch 500 at the trigger position, the controller releases the limitation on the operation of the dust collecting device after obtaining the signal that the detection switch 500 is in the trigger state, and allows the dust collecting device to operate or suspend operation as required.

If the dust bag assembly 200 is not placed back into the box 100, the trigger structure 400 cannot reach the ready position, and at this time, even if the box cover 300 is closed to the box 100, the box cover 300 cannot push the trigger structure 400 which is not in the ready position, and the trigger structure 400 cannot trigger the detection switch 500, during which time, the controller keeps limiting the dust collecting device from working based on the non-triggered state of the detection switch 500 until the dust bag assembly 200 is placed back into the box 100 and the box cover 300 is closed to the box 100.

Therefore, by adopting the scheme, the detection accuracy of whether the dust bag assembly 200 is in place and whether the box cover 300 covers the box body 100 can be further improved, the misjudgment risk is reduced, the dust collecting device can normally work as required, and the use performance is improved.

Referring to fig. 2, 4 and 5, in the present embodiment, the triggering structure 400 is provided with a first force-receiving portion 410, the first force-receiving portion 410 is located at a side of the triggering structure 400 close to the dust bag assembly 200, the dust bag assembly 200 is provided with a clamping plate 210 detachably connected to the box body 100 and a first pushing portion 211 attached to the clamping plate 210, and the first pushing portion 211 moves to an initial position with the clamping plate 210 installed in the box body 100 to push the first force-receiving portion 410 to move from the initial position to a ready position; the trigger structure 400 is provided with a second force-receiving portion 420, the second force-receiving portion 420 is located on one side of the trigger structure 400 close to the top of the box 100, one side of the box cover 300 close to the top of the box 100 is provided with a second thrust portion 310, and the second thrust portion 310 moves to the preparation position along with the cover 300 covering the top of the box 100 to push the second force-receiving portion 420 to move from the preparation position to the trigger position.

Based on the above structure, when the dust bag assembly 200 is placed back into the box 100 and the clamping plate 210 is installed in place, the first pushing portion 211 can push the first force-receiving portion 410 relatively, so that the triggering structure 400 moves from the initial position to the ready position; then, the cover 300 covers the box 100, and the second pushing portion 310 can push the second force-bearing portion 420 relatively, so that the trigger structure 400 moves from the preparation position to the trigger position, and the detection switch 500 is triggered. Therefore, by adopting the above scheme, the activities of the dust bag assembly 200 and the case cover 300 and the trigger structure 400 can be reliably associated, the structure is simple, the detection accuracy can be further improved, the misjudgment risk is reduced, and the use performance is further improved.

Referring to fig. 1, 4 and 6, in the present embodiment, the box 100 is provided with a mounting sidewall 122 and a slot 1221 formed on the mounting sidewall 122, the first force-receiving portion 410 is disposed through the mounting sidewall 122 at an initial position, and the clamping plate 210 is detachably mounted in the slot 1221 and attached to the mounting sidewall 122 to push the first force-receiving portion 410 to contract relative to the mounting sidewall 122.

By adopting the above scheme, the clamping plate 210 can be quickly and accurately mounted in place through the matching of the clamping plate 210 and the clamping groove 1221, so that the dust bag assembly 200 can be conveniently guided to be placed in place, and the first thrust portion 211 can be conveniently and relatively pushed against the first stress portion 410 to enable the trigger structure 400 to be moved from the initial position to the preparation position. Thus, the convenience of assembling the dust bag assembly 200 with the housing 100 can be improved, and the reliability of the association of the movement of the dust bag assembly 200 with the trigger structure 400 can be improved.

Referring to fig. 3, 4 and 6, in the present embodiment, at least one of the first force receiving portion 410 and the first thrust portion 211 is provided with a first guide surface 411, the first guide surface 411 is disposed obliquely with respect to a predetermined horizontal direction, and the first guide surface 411 is used for guiding the first thrust portion 211 to apply a first horizontal thrust to the first force receiving portion 410.

By adopting the above scheme, during the process that the dust bag assembly 200 is put into the box body 100 from top to bottom, the first pushing portion 211 can achieve transitional pushing fit with the first force-receiving portion 410 along the first guide surface 411, and gradually push the first force-receiving portion 410 to contract relative to the mounting sidewall 122, so as to cause the trigger structure 400 to move from the initial position to the ready position. Therefore, based on the arrangement of the first guide surface 411, the risk of the first thrust portion 211 and the first force receiving portion 410 being stuck in cooperation can be effectively reduced, the reliability of the association between the dust bag assembly 200 and the trigger structure 400 can be improved, the smoothness of the trigger structure 400 can be improved, and the usability can be improved.

Wherein, the first guide surface 411 provided on the first force receiving portion 410 faces upward and toward the first thrust portion 211; and the first guide surface provided to the first thrust portion 211 is directed downward and toward the first force receiving portion 410.

Referring to fig. 2, 4 and 5, in the present embodiment, at least one of the second force receiving portion 420 and the second thrust portion 310 is provided with a second guiding surface 421, the second guiding surface 421 is disposed obliquely with respect to the predetermined horizontal direction, the second guiding surface 421 is used for guiding the second thrust portion 310 to apply a second horizontal thrust to the second force receiving portion 420, and the second horizontal thrust is in accordance with the first horizontal thrust.

Based on the arrangement of the second guiding surface 421, in the process that the dust bag assembly 200 is placed in the box body 100 and the box cover 300 gradually covers the box body 100, the second pushing portion 310 can achieve transitional pushing and pushing cooperation with the second force receiving portion 420 along the second guiding surface 421, and gradually push the second force receiving portion 420 to move from the preparation position to the triggering position, so that the risk of jamming occurring in cooperation between the second pushing portion 310 and the second force receiving portion 420 can be effectively reduced, the reliability of the association of the movement of the box cover 300 and the triggering structure 400 can be improved, the degree of smoothness of the movement of the triggering structure 400 can be improved, and further the usability of the movement can be improved.

And through the arrangement that the direction of the second horizontal thrust is consistent with that of the first horizontal thrust, the moving path from the initial position, the preparation position to the trigger position of the trigger structure 400 is basically in a straight line, so that the moving smoothness of the trigger structure 400 can be further improved, the reset of the trigger structure 400 is particularly convenient, the risk of clamping stagnation of the trigger structure 400 is favorably reduced, and the reliability and the usability can be improved.

Referring to fig. 1, 4 and 5, in the present embodiment, the first pushing portion 211 is protruded on a side of the clamping plate 210 close to the trigger structure 400, and/or the second pushing portion 310 is protruded on a side of the cover 300 close to the trigger structure 400.

By adopting the above scheme, the pushing of the trigger structure 400 can be reliably and conveniently realized through the convex first thrust part 211 and/or the convex second thrust part 310, based on which, the reliability of the association between the dust bag assembly 200 and/or the box cover 300 and the activity of the trigger structure 400 can be further improved, and the activity stroke of the trigger structure 400 can be ensured and even prolonged, thereby further improving the service performance.

Referring to fig. 3, 4 and 5, in the present embodiment, the first pushing portion 211 pushes the first force-receiving portion 410 to move from the initial position to the preparation position along a first direction, and the second pushing portion 310 pushes the second force-receiving portion 420 to move from the preparation position to the triggering position along a second direction, wherein the first direction and the second direction are the same predetermined horizontal direction.

By adopting the above scheme, the moving path from the initial position, the preparation position to the trigger position of the trigger structure 400 is substantially a straight line, so that the moving smoothness of the trigger structure 400 can be further improved, especially, the reset of the trigger structure 400 is convenient, the risk of clamping stagnation of the trigger structure 400 is favorably reduced, and the reliability and the usability can be improved.

Referring to fig. 2, 4 and 5, in the present embodiment, the trigger structure 400 is convexly provided with a third pushing portion 450 for abutting against the detection switch 500.

By adopting the above scheme, the trigger structure 400 can reliably and continuously press the detection switch 500 through the third thrust portion 450 at the trigger position, so that the detection switch 500 maintains the trigger state, and the usability is better.

Optionally, the detection switch 500 is disposed on a side of the trigger structure 400 away from the case cover 300, so as to facilitate the horizontal space occupation of the trigger structure 400 and the detection switch 500, thereby facilitating the miniaturization design of the dust collecting device.

Referring to fig. 1, 4 and 5, in the present embodiment, the dust collecting apparatus further includes an elastic member 600, and the elastic member 600 elastically connects the trigger structure 400 and the box 100 to provide an elastic restoring force for the trigger structure 400 to move toward the initial position.

Here, while the trigger structure 400 moves from the initial position to the ready position and then from the ready position to the trigger position, the elastic member 600 elastically deforms and stores the elastic restoring force that moves the trigger structure 400 in the direction approaching the initial position when the pushing is released.

Specifically, the box cover 300 opens the box body 100 first, the box cover 300 releases the pushing of the trigger structure 400, the elastic force of the elastic member 600 can urge the trigger structure 400 to return from the trigger position to the preparation position, at this time, the detection switch 500 is already switched from the trigger state to the non-trigger state, then, the dust bag assembly 200 is taken out from the box body 100 again, the dust bag assembly 200 releases the pushing of the trigger structure 400, the elastic force of the elastic member 600 can further urge the trigger structure 400 to return from the preparation position to the initial position, during which, the detection switch 500 always maintains the non-trigger state, the controller maintains and limits the dust collecting device to work based on the non-trigger state of the detection switch 500 until the dust bag assembly 200 is put back to the box body 100 first and the box cover 300 covers the box body 100 again.

Therefore, by adopting the above-mentioned scheme, the trigger structure 400 can instantly move toward the initial position when the box cover 300 is released from pushing the trigger structure 400 by the elastic restoring force of the elastic member 600, so that the trigger detection switch 500 can be instantly released to instantly switch the detection switch 500 back to the non-triggered state, and the controller can instantly limit the operation of the dust collecting device, thereby improving the usability. The elastic restoring force of the elastic member 600 can also cause the trigger structure 400 to reset to the initial position, so that the trigger structure 400 and the detection switch 500 can be conveniently re-associated to detect whether the dust bag assembly 200 is in place or not and whether the box cover 300 covers the box body 100 or not, thereby improving the detection accuracy, ensuring that the dust collecting device can normally work as required and improving the use performance.

Referring to fig. 1, 3 and 4, in the present embodiment, the box 100 includes a box body 110, a dust bag holder 120 installed in the box body 110, and a detecting holder 130 connected to one side of the dust bag holder 120 away from the dust bag assembly 200, wherein the detecting holder 130 is provided with a limiting hole 131; the triggering structure 400 includes a triggering body 430 and a guiding post 440 connected to a side of the triggering body 430 away from the dust bag assembly 200, the guiding post 440 is slidably fitted in the limiting hole 131, and the elastic member 600 elastically connects the triggering body 430 and the detecting bracket 130.

It should be noted that the dust suction pipe 121 for being connected to the dust bag assembly 200 may be integrally formed with the dust bag holder 120, and the trigger structure 400, the detection switch 500 and the elastic member 600 may be assembled to the detection holder 130, and then assembled by detachably connecting the detection holder 130 to the dust bag holder 120. Therefore, the structural arrangement of the case 100 according to the present embodiment can facilitate the improvement of the processing convenience and the assembly convenience of the case 100 and the entire dust collecting device.

It should be further noted that the present embodiment provides a possible assembly implementation example based on the arrangement that the moving path of the triggering structure 400 from the initial position, the preparation position to the triggering position is substantially in a straight line. Specifically, the elastic member 600 is sleeved on the outer peripheral side of the guide post 440, and then the end of the guide post 440 is inserted into the limiting hole 131, based on this, the elastic member 600 elastically abuts between the side of the detection bracket 130 facing the trigger body 430 and the trigger body 430, and based on the insertion fit relationship between the guide post 440 and the limiting hole 131, the moving path of the trigger structure 400 is substantially a straight line.

Therefore, when the dust bag assembly 200 is placed back into the box body 100, the first pushing portion 211 can push the trigger structure 400, so that the trigger structure 400 moves from the initial position to the preparation position along the penetrating direction of the limiting hole 131, then, the box cover 300 covers the box body 100, the second pushing portion 310 can push the second force-receiving portion 420 to continue moving along the same direction, so that the trigger structure 400 further moves from the preparation position to the trigger position, so that the trigger structure 400 can immediately push the detection switch 500, so that the detection switch 500 is switched from the non-trigger state to the trigger state, and the controller immediately releases the limitation on the dust collecting device, and during the period, the elastic member 600 generates compression elastic deformation and stores force.

On the contrary, when the box cover 300 opens the box body 100, the second pushing portion 310 releases the pushing on the second force-receiving portion 420, the elastic member 600 can restore a portion of elastic deformation and urge the triggering structure 400 to instantly return from the triggering position to the preparation position, so as to urge the detecting switch 500 to instantly switch from the triggering state back to the non-triggering state and limit the dust collecting device to work, and then the dust bag assembly 200 is taken out from the box body 100, the first pushing portion 211 releases the pushing on the triggering structure 400, and the elastic member 600 can basically restore the elastic deformation and further urge the triggering structure 400 to return from the preparation position to the initial position, so as to facilitate the next related detection work to be unfolded.

Therefore, by adopting the above scheme, the moving path of the trigger structure 400 can be guided, so that the moving smoothness of the trigger structure 400 can be improved, the reset of the trigger structure 400 is facilitated, the risk of jamming of the trigger structure 400 can be further reduced, and the reliability and the usability can be further improved.

Referring to fig. 1, an embodiment of the utility model further provides a cleaning robot system, which includes a cleaning robot and a dust collecting device.

The cleaning robot can be a household or commercial service robot with the functions of garbage sweeping and garbage storage, such as a sweeper, a sweeping and mopping integrated machine, a floor scrubber and the like. In particular, when the cleaning robot is in operation, impurities such as dust, hair, or paper dust in the cleaning area may be stored in a trash storage chamber inside the cleaning robot. Therefore, after the cleaning robot works for a period of time, the dust outlet of the cleaning robot can be butted with the dust suction port of the dust collecting device, so that when the dust collecting device works, impurities originally stored in the garbage storage chamber inside the cleaning robot can be introduced into the dust bag assembly 200 through the dust suction port and the dust suction pipe 121 of the box body 100, and the transfer and collection of the impurities are completed; when the dust collecting device is suspended, the operator may open the cover 300 and the box 100, then take the dust bag assembly 200 out of the box 100, clean the impurities in the dust bag assembly 200, and after the cleaning is completed, put the dust bag assembly 200 back into the box 100 to wait for the next operation of the dust collecting device.

Example two

The difference between this embodiment and the first embodiment is:

referring to fig. 4 and 5, in the present embodiment, the first pushing portion 211 pushes the first force-receiving portion 410 to move from the initial position to the preparation position along a first direction, and the second pushing portion 310 pushes the second force-receiving portion 420 to move from the preparation position to the triggering position along a second direction, wherein the first direction is a horizontal direction and the second direction is a vertical direction.

By adopting the above scheme, the trigger structure 400 can move from the initial position to the preparation position along the first direction under the pushing action of the first pushing part 211, and then move from the preparation position to the trigger position along the second direction perpendicular to the first direction under the pushing action of the second pushing part 310, and trigger the detection switch 500. The detection switch 500 can be reliably triggered and released by the movement path setting of the trigger position according to the present embodiment.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents or improvements made within the spirit and principle of the present invention should be included in the scope of the present invention.
