When the dust collector is used, garbage such as dust, hair, fruit peels and the like on the ground can enter the dust collection assembly sequentially through the floor brush mechanism, the extension pipe and the filtering and separating assembly under the action of the vacuum source, but the dust collector is limited by the size and the weight of the household dust collector, the power of the vacuum source is not large, so that the suction force generated by the vacuum source is not large enough, and the dust collector often has residual garbage in the floor brush mechanism, the extension pipe and the filtering and separating assembly after cleaning work is finished. If the residual garbage is not cleaned in time, mould, rot and odor can be generated, so that the use of the machine is influenced, and the living environment is polluted.

Therefore, how to recover the garbage remaining in the vacuum cleaner becomes a problem to be solved in the field.

Furthermore, a transition hole is formed in the airflow channel and located between the first opening and the second opening, and the recovery auxiliary assembly is located in the recovery air channel and close to the transition hole.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. It should be apparent that the embodiments described in this application are only some embodiments of the present application, and not all embodiments of the present application. All other embodiments, which can be obtained by a person skilled in the art without making any inventive step based on the embodiments in the present application, are within the scope of protection of the present application.

Fig. 1 is an exploded view of a recovery apparatus a according to an embodiment of the present invention.

In the present embodiment, the recovery device a includes a casing 1, a recovery auxiliary assembly 2, and a recovery tank 3. The housing 1 has an air flow channel 11 and a floor brush base 1011 for receiving a cleaning device B (not shown), the air flow channel 11 has openings at both ends, wherein a first opening 112 of the air flow channel 11 communicates with the outside air, a second opening 111 of the air flow channel 11 is located in the floor brush base 1011, a transition hole 113 is further provided in the air flow channel 11, and the transition hole 113 is located between the first opening 112 and the second opening 111. The recovery auxiliary component 2 is arranged in the shell 1, in particular, the recovery auxiliary component 2 is arranged in the airflow channel 11 and is close to the transition hole 113, and the recovery auxiliary component 2 can close or open the transition hole 113 under the driving of external force. Note that, in the present embodiment, the recovery tub 3 and the airflow passage 11 in the casing 1 do not communicate with each other.

The recovery device a further comprises a suction device (not shown), which may be a vacuum pump or a suction fan, which is in communication with the air flow channel 11, and in particular, may be arranged in the air flow channel 11. When the air suction device is operated, the air suction device can suck the outside air into the air flow channel 11 through the first opening 112 and discharge the outside air out of the air flow channel 11 through the second opening 111, i.e. in the present embodiment, the first opening 112 corresponds to an air inlet and the second opening 111 corresponds to an air outlet.

In practice, the gas flow channel 11 in the housing 1 can be realized by various manufacturing processes, for example, by injecting molten plastic into a mold cavity by an integral molding process to obtain the housing 1 containing the gas flow channel 11.

Alternatively, the housing 1 may be composed of different components, and after the respective components are manufactured, the different components are combined together to obtain the housing 1 including the airflow passage 11. For example, the housing 1 may be divided into the duct upper cover 101, the duct lower cover 102, the bottom cover 103, and the cover 104, and the first opening 112 may be provided on the cover 104 and the second opening 111 may be provided in the duct upper cover 101, and when the duct upper cover 101 and the duct lower cover 102 are combined together, the airflow passage 11 may be formed, while the bottom cover 103 may fix the duct lower cover 102 and the cover 104 together. In practical applications, the first opening 112 may be configured to: the cover 104 is provided with a plurality of pores to form a filter screen structure. The screen structure forms a first opening 112 through which ambient air may enter the airflow passage 11. Further, the bottom cover 103 may be provided with a support structure, which may be used to fix the recovery aid assembly 2 and the suction device.

Optionally, when the air flow channel 11 is formed by the air duct upper cover plate 101 and the air duct lower cover plate 102, an air duct sealing ring 114 may be disposed between the air duct upper cover plate 101 and the air duct lower cover plate 102 to ensure the sealing performance of the air flow channel 11.

In an realizable embodiment, a transition aperture 113 is also provided in the gas flow channel 11, the transition aperture 113 being located between the first opening 112 and the second opening 111. Specifically, a shielding plate having an open-hole structure may be provided at a certain position of the air flow passage 11, so that the transition hole 113 is formed through the shielding plate. The transition hole 113 may divide the air flow passage 11 into two parts, i.e., a part near the second opening 111 (hereinafter referred to as an a duct for convenience of description) and a part near the first opening 112 (hereinafter referred to as a b duct for convenience of description).

The recovery auxiliary assembly 2 is located in the airflow passage 11 and close to the transition hole 113, and the recovery auxiliary assembly 2 can move in the housing 1 under the driving of an external force so as to contact or separate from the transition hole 113. When the recovery aid member 2 is in contact with the transition hole 113, the recovery aid member 2 may completely shield the transition hole 113, thereby closing the transition hole 113; when the recovery aid member 2 is disengaged from the transition hole 113, the transition hole 113 will be reopened.

In one implementable embodiment, the recovery aid assembly 2 includes a transition gland plate 21 and a reciprocator 22. The transition escutcheon plate 21 is connected to the reciprocator 22 and the transition escutcheon plate 21 is linearly reciprocable in a direction orthogonal to the transition aperture 113 under the drive of the reciprocator 22 so that the transition escutcheon plate 21 can contact or disengage the transition aperture 113 and ultimately so that the transition escutcheon plate 21 can close or open the transition aperture 113. It is specifically noted that the cross-sectional area of the transition escutcheon plate 21 is not less than the cross-sectional area of the transition aperture 113 so that the transition escutcheon plate 21 may completely obscure the transition aperture 113 when the transition escutcheon plate 21 is in contact with the transition aperture 113.

Alternatively, the reciprocator 22 may take a variety of configurations. For example, the reciprocating mechanism 22 may be a cam-and-slot arrangement, an eccentric arrangement, or a worm and gear arrangement. The reciprocating mechanism 22 may be disposed inside the housing 1 and connected to a first driving device 23 (e.g., a driving motor), and the first driving device 23 may drive the reciprocating mechanism 22 to move, so that the transition hole cover plate 21 connected to the reciprocating mechanism 22 linearly reciprocates in a direction orthogonal to the transition hole 113.

In an implementation, the reciprocating mechanism 22 includes a driving member 221 and an intermediate member 222, wherein one end of the intermediate member 222 is connected to the transition hole cover plate 21, and the other end of the intermediate member 222 is connected to the driving member 221, and the intermediate member 222 can rotate under the driving of the driving member 221, so as to drive the transition hole cover plate 21 to reciprocate linearly in a direction orthogonal to the transition hole 113. Taking a crank-slider mechanism as an example, the intermediate piece 222 may be a slider in the crank-slider mechanism, the driving piece 221 may be a crank in the crank-slider mechanism, the intermediate piece 222 and the driving piece 221 are hinged through a connecting rod, and the transition hole cover plate 21 is rigidly connected to the intermediate piece 222, so that the driving piece 221 can drive the transition hole cover plate 21 to make a linear reciprocating motion by driving the intermediate piece 222.

In practical applications, by adjusting the positional relationship among the driver 221, the intermediate piece 222, and the transition escutcheon plate 21, the displacement and path of the transition escutcheon plate 21 can be precisely controlled, such that the transition escutcheon plate 21 can reciprocate linearly in a direction orthogonal to the transition orifice 113, and when the intermediate piece 222 moves to an extreme position, the transition escutcheon plate 21 can just abut against the transition orifice 113 without damaging the structure of the transition orifice 113. The specific structure of the reciprocating mechanism 22 can refer to the existing linear reciprocating structure, and the detailed description of the present application is omitted.

In practical applications, to shorten the movement stroke of the intermediate member 222 and reduce the volume of the reciprocating mechanism 22, the intermediate member 222 may be configured to perform a complete rotation movement under the driving of the driving member 221, that is, the intermediate member 222 may approach the transition hole 113 in a direction orthogonal to the transition hole 113 under the driving of the driving member 221, when the intermediate member 222 moves to the extreme position, the transition hole cover plate 21 just may abut against the transition hole 113 without damaging the structure of the transition hole 113, at this time, if the driving member 221 continues to move, the driving member 221 cannot continue to apply a force to the intermediate member 222, and the intermediate member 222 does not change the current position due to the movement of the driving member 221, in other words, when the driving member 221 completes a complete rotation movement, the intermediate member 222 completes only a half of the complete rotation movement. In a specific implementation, reference may be made to an intermittent linear reciprocating mechanism, and a specially-shaped link or a chute is provided between the intermediate member 222 and the driving member 221, so as to implement a rotation motion of the intermediate member 222 in a non-complete circle.

When the intermediate member 222 cannot perform a full rotation movement under the driving of the driving member 221, the problem of resetting the intermediate member 222 needs to be considered. In an implementable embodiment, the recovery aid assembly 2 further comprises a tension spring 24, one end of the tension spring 24 being connected to the intermediate member 222, the other end of the tension spring 24 being connected to the housing 1. Since the position where the tension spring 24 is connected to the housing 1 is fixed, when the intermediate member 222 moves in the housing 1, the intermediate member 222 exerts a force on the tension spring 24, so that the tension spring 24 is elastically deformed. For the sake of understanding, the present application refers to the position of the intermediate member 222 in the housing 1 where the tension spring 24 is not elastically deformed as the initial position of the intermediate member 222. It should be noted that when the intermediate member 222 is in the initial position, the driving member 221 is simultaneously located at a position where a force can be applied to the intermediate member 222, that is, when the driving member 221 starts to move, the driving member 221 can drive the intermediate member 222 to approach the transition hole 113 from the initial position in a direction orthogonal to the transition hole 113.

When the intermediate piece 222 approaches the transition hole 113 in the direction orthogonal to the transition hole 113 under the driving of the driving piece 221, the tension spring 24 will be stretched by the intermediate piece 222; when the intermediate member 222 moves to the extreme position, as the driving member 221 continues to move, the driving member 221 cannot apply force to the intermediate member 222 any more, and the intermediate member 222 will return to the initial position under the action of the tension spring 24, so that the intermediate member 222 is reset to wait for the next movement cycle to start.

In an implementable embodiment, the recovery aid assembly 2 further comprises a position sensor 26, the position sensor 26 being located on the intermediate piece 222 to detect the position of the intermediate piece 22 in the housing 1. In practical applications, the position sensor 26 may be a hall element, and specifically, a magnetic device may be disposed in the housing 1 near the moving path of the intermediate member 22, so that when the intermediate member 22 moves in the housing 1, the hall element can detect the change of the magnetic field, thereby calculating the position of the intermediate member 22 in the housing 1. Further, the position sensor 26 may also feed back position information of the middleware 22 to a controller (not shown) provided in the recovery device a, so that the controller may adjust the operating state of the recovery device a according to a preset control program. How the controller controls the operating state of the recovery device a will be described later.

Optionally, the reciprocating mechanism 22 is a cam-and-slot arrangement. Specifically, the driving member 221 includes a cam crankshaft 2211 and a bearing 2212, the intermediate member 222 has an annular sliding groove (not shown), one end of the bearing 2212 is connected to the cam crankshaft 2211, the other end of the bearing 2212 is connected to the annular sliding groove, and the output shaft of the first driving device 23 is connected to the cam crankshaft 2211. The annular chute is configured to: when the bearing 2212 makes a circular motion, the bearing 2212 in the annular sliding chute can drive the intermediate member 222 to make a linear reciprocating motion. Thus, when the cam crankshaft 2211 performs a circular motion under the action of the first driving device 23, the cam crankshaft 2211 can simultaneously drive the bearing 2212 to perform a circular motion, and since one end of the bearing 2212 is located in the annular sliding chute, the bearing 2212 slides in the annular sliding chute and applies an acting force to the inner wall of the annular sliding chute, so as to drive the intermediate member 222 to perform a linear reciprocating motion.

Optionally, in order to improve the sealing effect of the transition hole cover plate 21 on the transition hole 113, the recovery auxiliary assembly 2 further includes a cover plate sealing ring 25, the cover plate sealing ring 25 is matched with the outer contour of the transition hole cover plate 21 and is sleeved on the outer peripheral surface of the transition hole cover plate 21, that is, the transition hole cover plate 21 is embedded in the cover plate sealing ring 25. The cover plate sealing ring 25 can be made of rubber and has a fold structure, so that when the transition hole cover plate 21 is in contact with the transition hole 113, the transition hole cover plate 21 can extrude the cover plate sealing ring 25, the fold structure of the cover plate sealing ring 25 is deformed, and a better sealing effect is obtained.

Referring to fig. 2 and 3 together, fig. 2 is a schematic structural diagram of a cleaning device B (such as a handheld vacuum cleaner, a sweeping robot, etc.) placed on a recycling device a, and fig. 3 is a schematic structural diagram of the cleaning device B separated from the recycling device a. For convenience of description, the cleaning device B is a handheld vacuum cleaner as an example.

In an implementable embodiment, the cleaning device B has a filtering and separating assembly B1, an elongated tube B2, a floor brush mechanism B3 and a dust bucket B4, the recovery bucket 3 is provided with a recovery receiving opening 30, when the cleaning device B is placed on the recovery device a, the floor brush mechanism B3 is located on the floor brush base 1011, and the dust bucket B4 is communicated with the recovery bucket 3 through the recovery receiving opening 30. In practical application, the air duct upper cover plate 101 can be manufactured according to the outer contour of the floor brush mechanism B3, so that the surface shape of the air duct upper cover plate 101 is matched with the outer contour of the floor brush mechanism B3, and the air duct upper cover plate 101 is used as the floor brush seat 1011. The specific location of the second opening 111 on the duct upper deck 101 may be set with reference to the location of the floor brush mechanism B3 on the duct upper deck 101 such that the second opening 111 is located just below the floor brush mechanism B3 when the floor brush mechanism B3 is placed on the duct upper deck 101.

Optionally, the housing 1 is further provided with a floor brush sealing ring 12, so that when the floor brush mechanism B3 is placed on the floor brush base 1011, the floor brush sealing ring 12 can form a closed space between the floor brush base 1011 and the floor brush mechanism B3. Specifically, the ground brush sealing ring 12 can be made of rubber and arranged on the outer peripheral surface of the ground brush seat 1011, and meanwhile, the ground brush sealing ring 12 can extend to the inner part of the ground brush seat 1011 to a specified length, so that when the ground brush mechanism B3 is placed on the ground brush seat 1011, the ground brush sealing ring 12 can wrap the ground brush mechanism B3, and the sealing effect of the ground brush sealing ring 12 is further improved.

In one practical embodiment, a trigger probe 1012 is provided on the floor brush base 1011, the trigger probe 1012 protrudes from the surface of the floor brush base 1011, and the trigger probe 1012 contacts the floor brush mechanism B3 when the floor brush mechanism B3 is placed on the floor brush base 1011. In practical application, the trigger probe 1012 can be arranged at a position where the floor brush base 1011 contacts with the floor brush mechanism B3, a spring is sleeved outside the trigger probe 1012, and when the floor brush mechanism B3 is not placed on the floor brush base 1011, the trigger probe 1012 protrudes out of the outer surface of the floor brush base 1011 under the action of the spring; when the floor brush mechanism B3 is placed on the floor brush holder 1011, the floor brush mechanism B3 contacts the trigger probe 1012 and presses the trigger probe 1012 into the floor brush holder 1011. The trigger probe 1012 can be electrically connected to a controller in the recycling device a, and when the trigger probe 1012 is pressed into the floor brush holder 1011 by the floor brush mechanism B3, the trigger probe 1012 will send a signal to the controller, so that the recycling device a starts a recycling procedure to recycle the garbage remaining in the cleaning device B.

The operation principle of the recovery apparatus a will be described with reference to fig. 1, 2, 4, and 5.

The cleaning device B is placed on the recycling device a, at this time, the dust barrel B4 is communicated with the recycling barrel 3 through the recycling receiving opening 30, the ground brush sealing ring 12 wraps the ground brush mechanism B3, a sealed space is formed between the ground brush seat 1011 and the ground brush mechanism B3, the ground brush mechanism B3 is located above the second opening 111 of the airflow channel 11, the ground brush mechanism B3 presses the trigger probe 1012 into the ground brush seat 1011, the intermediate piece 222 is in an initial position, and the intermediate piece 222 is configured to make an incomplete circle rotary motion under the driving of the driving piece 221.

The trigger probe 1012 sends a signal to the controller in the recovery device a so that the recovery device a starts the recovery process, and the controller controls the suction device in the recovery device a to start operating, the suction device sucks the outside air into the airflow passage 11 through the first opening 112, and the air entering the airflow passage 11 flows through the first opening 112, the transition hole 113 and the second opening 111 in sequence, and enters the floor brush mechanism B3. At the same time, the controller controls the first driving device 23 to start working, the first driving device 23 drives the cam crankshaft 2211 to start rotating, the cam crankshaft 2211 drives the bearing 2212 to make a circular motion, and since one end of the bearing 2212 is located in the annular sliding chute, the bearing 2212 slides in the annular sliding chute and applies a force to the inner wall of the annular sliding chute, so as to drive the intermediate member 222 to start approaching the transition hole 113 along a direction orthogonal to the transition hole 113. When the intermediate member 222 moves in a direction approaching the transition hole 113, the tension spring 24 connected to the intermediate member 222 will be stretched by the intermediate member 222, and thus the intermediate member 222 will be subjected to a force applied by the tension spring 24 in a direction away from the transition hole 113. During the approach of the intermediate piece 222 to the transition hole 113 in a direction orthogonal to the transition hole 113, the transition hole cover plate 21 connected to the intermediate piece 222 will also move in a direction approaching the transition hole 113.

When the transition escutcheon plate 21 is moved into contact with the transition orifice 113, the transition orifice 113 will be closed by the cooperation of the transition escutcheon plate 21 and the cover seal 25. At this time, the air flow passage 11 may be regarded as being divided into two parts which are not communicated with each other by the transition hole cover 21 and the cover sealing ring 25, that is, a part of the air duct (a air duct) near the second opening 111 and a part of the air duct (b air duct) near the first opening 112.

The position sensor 26 can feed back the position data of the intermediate piece 22 in the casing 1 at the moment to the controller in the recovery device a, the controller stores the position data of the intermediate piece 22 when the transition hole cover plate 21 contacts the transition hole 113, and after data comparison, the controller can judge that the transition hole cover plate 21 has closed the transition hole 113, so that the controller can control the first driving device 23 to stop working, so that the cam crankshaft 2211 and the bearing 2212 keep the current positions unchanged, so that the bearing 2212 can maintain the position of the intermediate piece 222 in the casing 1, and the transition hole cover plate 21 keeps the state of closing the transition hole 113.

Since the air suction device is continuously operated in the above process, when the transition hole 113 is closed, the air in the b duct will be continuously accumulated, so that the air pressure in the b duct is increased, and thus the air pressure in the b duct will be greater than the air pressure in the a duct.

After the transition hole cover 21 closes the transition hole 113 for a certain period of time, the controller may control the first driving device 23 to resume operation, and the cam crankshaft 2211 and the bearing 2212 will resume movement. Due to the special structure of the annular chute, when the bearing 2212 moves to the highest point of the annular chute under the driving of the cam crankshaft 2211, the bearing 2212 will not apply an acting force on the inner wall of the annular chute any more, so the intermediate piece 222 will move in the direction away from the transition hole 113 under the action of the tension spring 24, thereby driving the transition hole cover plate 21 connected with the intermediate piece 222 to be separated from the transition hole 113, meanwhile, the cover sealing ring 25 will also be separated from the transition hole 113, the transition hole 113 will be reopened, the air duct a and the air duct b are re-communicated, and since the air pressure of the air duct b is greater than that of the air duct a, the air in the air duct b will rapidly enter the air duct a.

Since the air in the air duct B rapidly enters the air duct a in a short time and the volume of the air duct a is fixed, the air flow rate in the air duct a is increased, and correspondingly, the speed of the air in the air duct a entering the floor brush mechanism B3 through the second opening 111 is increased, which is equivalent to increasing the speed of the air entering the cleaning device B, so that the air entering the cleaning device B can have a better scouring effect on the garbage remained in the cleaning device B. The air entering the cleaning device B flows through the floor brush mechanism B3, the lengthening pipe B2, the filtering and separating assembly B1 and the dust barrel B4 in sequence and finally enters the recovery barrel 3 through the recovery receiving port 30, and in the flowing process of the air, the residual garbage in the cleaning device B enters the recovery barrel 3 together, so that the effect of recovering the residual garbage in the cleaning device B is realized, and the phenomenon of mildew generation or rotting and smelling caused by untimely cleaning of the residual garbage is avoided.

When the intermediate member 222 moves to the initial position under the action of the tension spring 24, the intermediate member 222 will remain stationary, and the bearing 2212 continues to move under the action of the cam crankshaft 2211 until the bearing 2212 exerts a force on the inner wall of the annular chute again, so as to drive the intermediate member 222 to start the next movement cycle.

It should be noted that, during the actual usage, the user can also determine whether the transition hole 113 is closed by the transition hole cover 21 according to the sound emitted by the recovery device a. For example, when the transition hole cover 21 closes the transition hole 113, as the air suction device continues to work, the air accumulated in the b air duct will increase, and accordingly, the air pressure in the b air duct will increase, and the air suction device will need more power when sucking the outside air into the b air duct, so that the noise generated by the air suction device will increase, and the user can determine whether the transition hole 113 has been closed through the change of the noise of the air suction device. When the user manually controls the recovery state of the recovery device a, the open/close state of the transition hole 113 may be controlled using the above-described determination method to prevent the suction device from being damaged due to an excessively high load.

Because the air pressure in the b air duct is greater than the air pressure in the a air duct, when the transition hole cover plate 21 is separated from the transition hole 113, the air in the b air duct will prevent the transition hole cover plate 21 from moving in a direction away from the transition hole 113, and at the moment when the transition hole cover plate 21 is separated from the transition hole 113, an excessive pressure difference between the a air duct and the b air duct may cause the air flow in the air flow channel 11 to form a strong impact effect on the transition hole cover plate 21, which may cause the transition hole cover plate 21 to shake, causing the transition hole cover plate 21 to be unable to move stably, and at the same time, the impact effect may also affect the driving member 221 and the first driving device 23, causing the load of the driving member 221 and the first driving device 23 to be excessive, and causing the failure of the recovery device a. Therefore, in practical applications, consideration needs to be given to reducing the impact effect of the airflow on the transition escutcheon plate 21 and reducing the resistance of the air in the b-duct to the transition escutcheon plate 21.

In an implementation, the recovery assistance component 2 further comprises a fixing member 27, wherein the side of the middle member 222 facing the transition hole 113 has a protrusion 2221, the fixing member 27 is connected with the transition hole cover plate 21, and when the fixing member 27 is connected with the transition hole cover plate 21, a cavity with an open structure can be formed between the fixing member 27 and the transition hole cover plate 21, and the protrusion 2221 can enter the cavity through the open structure, so that a part of the protrusion 2221 (for convenience, the part of the structure is referred to as a contact part) is located in the cavity. The cavity is configured such that the length of the cavity is greater than the length of the contact portion in a direction orthogonal to the transition hole 113, so that the contact portion can move in the cavity in a direction orthogonal to the transition hole 113. It should be noted in particular that the fixing member 27 also has a blocking structure to prevent the contact portion from being disengaged from the above-mentioned open structure of the cavity when the contact portion moves in the cavity in a direction orthogonal to the transition hole 113. The transition escutcheon plate 21 is provided with a pressure relief hole 211, and the pressure relief hole 211 is located in the projection range of the projection 2221 of the transition escutcheon plate 21, i.e. when a contact portion in the projection 2221 contacts the transition escutcheon plate 21, the contact portion can close the pressure relief hole 211.

Optionally, the recovery sub-assembly 2 further comprises an intermediate sealing ring 28, wherein the intermediate sealing ring 28 is connected with a side of the protrusion 2221 facing the transition hole 113, that is, the intermediate sealing ring 28 is connected with a contact portion in the protrusion 2221, so as to improve the sealing performance of the contact portion on the pressure relief hole 211.

The fixing member 27, the transition hole cover plate 21 having the pressure relief hole 211, the middle piece 222 having the protrusion 2221, and the middle piece sealing ring 28 together constitute a pressure relief mechanism, which can reduce the impact effect of the airflow on the transition hole cover plate 21 and the resistance of the air in the air duct to the transition hole cover plate 21 when the transition hole cover plate 21 is separated from the transition hole 113.

The operation principle of the recovery apparatus a will be described with reference to fig. 1, 2, 6, and 7.

The cleaning device B is placed on the recycling device a, at this time, the dust barrel B4 is communicated with the recycling barrel 3 through the recycling receiving opening 30, the ground brush sealing ring 12 wraps the ground brush mechanism B3, a sealed space is formed between the ground brush base 1011 and the ground brush mechanism B3, the ground brush mechanism B3 is located above the second opening 111 of the airflow channel 11, the ground brush mechanism B3 presses the trigger probe 1012 into the ground brush base 1011, the intermediate piece 222 is in the initial position, the protruding portion 2221 of the intermediate piece 222 is partially located in the cavity formed by the fixing piece 27 and the transition hole cover plate 21 (i.e. the contact portion in the protruding portion 2221 is located in the cavity formed by the fixing piece 27 and the transition hole cover plate 21), and the intermediate piece 222 is configured to make an incomplete rotation movement under the driving of the driving piece 221.

The trigger probe 1012 sends a signal to a controller in the recovery apparatus a so that the recovery apparatus a starts the recovery process, and the controller controls an air suction device in the recovery apparatus a to start operating, which sucks the outside air into the air flow path 11 through the first opening 112. At the same time, the controller controls the first driving device 23 to start working, the first driving device 23 drives the cam crankshaft 2211 to start rotating, the cam crankshaft 2211 drives the bearing 2212 to make a circular motion, and since one end of the bearing 2212 is located in the annular sliding chute, the bearing 2212 slides in the annular sliding chute and applies a force to the inner wall of the annular sliding chute, so as to drive the intermediate member 222 to start approaching the transition hole 113 along a direction orthogonal to the transition hole 113. When the intermediate member 222 moves in a direction approaching the transition hole 113, the tension spring 24 connected to the intermediate member 222 will be stretched by the intermediate member 222, and thus the intermediate member 222 will be subjected to a force applied by the tension spring 24 in a direction away from the transition hole 113.

During the process that the intermediate piece 222 approaches the transition hole 113 in the direction orthogonal to the transition hole 113, the contact portion located in the cavity will approach the transition hole 113 in the direction orthogonal to the transition hole 113, and since the length of the cavity in the direction orthogonal to the transition hole 113 is fixed, after the contact portion moves a certain distance, the contact portion will contact the transition hole cover plate 21 and push the transition hole cover plate 21 to approach the transition hole 113 in the direction orthogonal to the transition hole 113, and at this time, the pressure relief hole 211 on the transition hole cover plate 21 will be sealed by the intermediate piece sealing ring 28 on the contact portion.

After the transition hole cover 21 closes the transition hole 113 for a certain period of time, the controller may control the first driving device 23 to resume operation, and the cam crankshaft 2211 and the bearing 2212 will resume movement. Due to the special structure of the annular chute, when the bearing 2212 moves to the highest point of the annular chute under the driving of the cam crankshaft 2211, the bearing 2212 will not apply an acting force on the inner wall of the annular chute any more, so the intermediate piece 222 will move in the direction away from the transition hole 113 under the action of the tension spring 24, so that the contact portion and the intermediate piece sealing ring 28 connected to the contact portion move in the direction away from the transition hole 113 at the same time, the pressure relief hole 211 on the transition hole cover plate 21 will be opened, the air in the air duct b will enter the air duct a through the pressure relief hole 211, and thus the air pressure in the air duct b will decrease, thereby reducing the air pressure difference between the air duct a and the air duct b. Accordingly, the impact effect of the air flow in the air flow passage 11 on the transition escutcheon plate 21, and the resistance of the air in the b duct to the transition escutcheon plate 21, will also be reduced.

As the contact portion continues to move in the direction away from the transition hole 113, the contact portion will contact with the blocking structure in the fixing member 27, so as to push the fixing member 27 to move in the direction away from the transition hole 113, because the fixing member 27 is connected with the transition hole cover plate 21, the fixing member 27 will drive the transition hole cover plate 21 to move in the direction away from the transition hole 113, and finally the transition hole cover plate 21 and the cover sealing ring 25 are simultaneously separated from the transition hole 113, the transition hole 113 will be reopened, the air duct a and the air duct b are re-communicated, because the air pressure of the air duct b is still greater than the air pressure of the air duct a, the air in the air duct b will rapidly enter the air duct a.

When the intermediate member 222 moves to the initial position under the action of the tension spring 24, the intermediate member 222 will remain stationary, and the bearing 2212 continues to move under the driving of the cam crankshaft 2211 until the bearing 2212 exerts a force on the inner wall of the annular chute again, so that the intermediate member 222 is driven to start the next movement cycle.

Therefore, since the recovery device a is provided with the pressure relief mechanism, when the transition hole cover plate 21 and the cover sealing ring 25 are separated from the transition hole 113, the impact effect of the air flow in the air flow channel 11 on the transition hole cover plate 21 can be weakened, so that the motion of the transition hole cover plate 21 is more stable, and the load of the driving element 221 and the first driving device 23 is not suddenly increased.

In the above embodiment, the recycling bin 3 is not communicated with the air flow channel 11 in the housing 1, the air suction device is disposed outside the recycling bin 3 and is communicated with the air flow channel 11, the air suction device can suck the outside air into the air flow channel 11 through the first opening 112, the air entering the air flow channel 11 sequentially flows through the second opening 111, the floor brush mechanism B3, the lengthened pipe B2, the filtering and separating assembly B1 and the dust bin B4 and finally enters the recycling bin 3, and from the analysis of the overall flow condition of the air flow, it can be regarded as that the residual garbage in the cleaning device B is blown into the recycling bin 3 by the air flow. In another practical embodiment, the recycling bin 3 can be communicated with the airflow channel 11 in the casing 1, and an air suction device can be arranged in the recycling bin 3, the air suction device can suck the air in the cleaning device B into the recycling bin 3, and the recycling bin 3 is also provided with an air outlet which is communicated with the outside air, so that after the air in the cleaning device B is sucked into the recycling bin 3 by the air suction device, the air can enter the outside air through the air outlet, and the whole process can be regarded as that the residual garbage in the cleaning device B is sucked into the recycling bin 3 by the airflow, and the detailed description of the embodiment will be given below.

Referring to fig. 8 and 9 together, in the present embodiment, the recycling apparatus a still includes a housing 1, a recycling auxiliary assembly 2, and a recycling bin 3. The housing 1 is provided with an air flow channel 11, a first opening 112 of the air flow channel 11 is communicated with the recycling bin 3 and is communicated with the outside air through an air outlet arranged in the recycling bin 3, a second opening 111 of the air flow channel 11 is positioned in the floor brush seat 1011, a transition hole 113 is further arranged in the air flow channel 11, the transition hole 113 is positioned between the first opening 112 and the second opening 111, the recycling auxiliary component 2 is positioned in the air flow channel 11 and is close to the transition hole 113, and the recycling auxiliary component 2 can close or open the transition hole 113 under the driving of external force. The air suction device is disposed in the recycling bin 3, and when the air suction device is operated, the air suction device can suck the air in the cleaning device B into the air flow channel 11 through the second opening 111 and into the recycling bin 3 through the first opening 112, where the second opening 111 is equivalent to an air inlet and the first opening 112 is equivalent to an air outlet. Be provided with filtering component and gas vent in the recycling bin 3, the air current that gets into in the recycling bin 3 can be filtered by above-mentioned filtering component, and rubbish such as hair, dust will be retained in recycling bin 3 like this, and the air current after the filtration will get into the outside air through the gas vent in, and prior art can be referred to the concrete structure of above-mentioned filtering component and gas vent, and the here is no longer repeated.

Regarding the specific structure of the recovery auxiliary component 2, the present embodiment is the same as the above-mentioned embodiment in which the recovery bucket 3 and the airflow channel 11 are not communicated with each other, and detailed description is omitted here, and only different parts of the two embodiments will be described in detail below.

In this embodiment, the casing 1 may be divided into an upper air duct cover 101, a lower air duct cover 102, a bottom cover 103, and a cover 104, when the upper air duct cover 101 and the lower air duct cover 102 are combined together, the airflow path 11 may be formed, the bottom cover 103 may fix the lower air duct cover 102 and the cover 104 together, the second opening 111 is located in the upper air duct cover 101, and the first opening 112 is disposed on the cover 104 and located at a position where the cover 104 is connected to the recycling bin 3. Accordingly, the recycling bin 3 is provided with a docking member at a position corresponding to the first opening 112, and the docking member can communicate the recycling bin 3 with the airflow channel 11, so that the airflow can enter the recycling bin 3 through the airflow channel 11. It should be noted that the position of the first opening 112 in fig. 8 and 9 is only schematic, and in practical applications, the specific position of the first opening 112 on the cover 104 can be adjusted according to practical structures, so long as the recycling bin 3 can be communicated with the airflow channel 11 through the first opening 112.

In an implementable embodiment, when the air suction device is operated, the air suction device can draw the air in the recycling bin 3 out and discharge the air into the outside air through the air outlet arranged on the recycling bin 3, and the air in the air flow channel 11 will also flow through the recycling bin 3 and be drawn out by the air suction device because the first opening 112 of the air flow channel 11 is communicated with the recycling bin 3, so that the air pressure in the air flow channel 11 is lower than that of the outside air, and the outside air will enter the air flow channel 11 through the second opening 111 and then enter the recycling bin 3 through the first opening 112 under the action of the pressure difference.

Alternatively, the airflow passage 11 may be configured to gradually converge from the first opening 112 to the second opening 111, that is, the cross-sectional area of the first opening 112 is the largest, and the cross-sectional area of the air duct between the first opening 112 and the second opening 111 is gradually reduced, and when reaching the second opening 111, the cross-sectional area of the second opening 111 is the smallest. In this way, the flow rate of the air flow generated by the suction means is maximized at the second opening 111, so that the suction effect of the recovery means a on the residual waste can be increased.

The operation principle of the recovery apparatus a will be described with reference to fig. 1, 2, 8 and 9.

The cleaning device B is placed on the recycling device a, at this time, the ground brush sealing ring 12 wraps the ground brush mechanism B3, the ground brush mechanism B3 is located above the second opening 111 of the airflow channel 11, and the ground brush mechanism B3 presses the trigger probe 1012 into the ground brush seat 1011, and the intermediate member 222 is configured to make an incomplete revolution movement under the driving of the driving member 221. The recovery device a starts the recovery process, the suction device in the recovery tub 3 starts to be started, so that a negative pressure is generated in the airflow path 11, and the gas in the floor brush mechanism B3 flows through the second opening 111, the transition hole 113 and the first opening 112 in sequence, enters the recovery tub 3, and is then discharged into the outside air through the exhaust port provided in the recovery tub 3.

When the intermediate member 222 is at the initial position, the first driving device 23 drives the cam crankshaft 2211 to rotate, the cam crankshaft 2211 drives the bearing 2212 to make a circular motion, and since one end of the bearing 2212 is located in the annular sliding chute, the bearing 2212 slides in the annular sliding chute and applies a force to the inner wall of the annular sliding chute, so as to drive the intermediate member 222 to approach the transition hole 113 in a direction orthogonal to the transition hole 113. Meanwhile, when the intermediate member 222 moves in a direction approaching the transition hole 113, the tension spring 24 connected to the intermediate member 222 will be stretched by the intermediate member 222, and thus the intermediate member 222 will receive a force applied by the tension spring 24 in a direction away from the transition hole 113. During the approach of the intermediate piece 222 to the transition hole 113 in a direction orthogonal to the transition hole 113, the transition hole cover plate 21 connected to the intermediate piece 222 will also move in a direction approaching the transition hole 113.

Since the air suction device is continuously operated in the above process, after the transition hole 113 is closed, the air in the air duct b will be sucked into the recycling bin 3, and the air in the air duct a will not be sucked into the recycling bin 3 because the air in the air duct a is blocked by the transition hole cover plate 21 and the cover plate sealing ring 25, so that the air pressure in the air duct a will be greater than the air pressure in the air duct b.

After the transition hole cover 21 closes the transition hole 113 for a certain period of time, the controller may control the first driving device 23 to resume operation, and the cam crankshaft 2211 and the bearing 2212 will resume movement. Due to the special structure of the annular chute, when the bearing 2212 moves to the highest point of the annular chute under the driving of the cam crankshaft 2211, the bearing 2212 will not apply an acting force on the inner wall of the annular chute any more, so the intermediate piece 222 will move in the direction away from the transition hole 113 under the action of the tension spring 24, thereby driving the transition hole cover plate 21 connected with the intermediate piece 222 to be separated from the transition hole 113, meanwhile, the cover sealing ring 25 will also be separated from the transition hole 113, the transition hole 113 will be reopened, the air duct a and the air duct b are re-communicated, and since the air pressure of the air duct a is greater than that of the air duct b, the air in the air duct a will rapidly enter the air duct b.

Because the air in the air duct a rapidly enters the air duct B in a short time, the air pressure in the air duct a will rapidly decrease, the air in the floor brush mechanism B3 will rapidly enter the air duct a to replenish the lost air, which is equivalent to increasing the speed of the air in the floor brush mechanism B3 entering the air flow channel 11, i.e. increasing the suction force of the air suction device to the floor brush mechanism B3, meanwhile, because the floor brush mechanism B3 is wrapped by the floor brush sealing ring 12, a closed space is formed between the floor brush seat 1011 and the floor brush mechanism B3, the air outside the cleaning device B will not enter the air flow channel 11, which further increases the suction force of the air suction device to the floor brush mechanism B3, so that the recovery device a can better recover the residual garbage in the floor brush mechanism B3 (the flow direction of the air in the above process can refer to the arrow direction in fig. 9).

Because the filtering and separating assembly B1, the lengthened pipe B2 and the ground brush mechanism B3 in the cleaning device B are communicated, residual garbage in the filtering and separating assembly B1 and the lengthened pipe B2 can be recovered by the recovery device A through the ground brush mechanism B3, so that all residual garbage in the cleaning device B can be recovered by the recovery device A, and the phenomenon that mildew or rot and odor are generated due to the fact that the residual garbage is not cleaned in time is avoided.

Similarly, the recycling device a may also have a pressure relief mechanism, and the specific working principle of the pressure relief mechanism can be referred to the relevant contents in the foregoing embodiments, and will not be described herein again.

The present application additionally provides an implementable embodiment in which the specific structure of the recovery assistance assembly 2 is different from the above-described embodiment.

Referring to fig. 10 and 11 together, the recovery aid assembly 2 includes a transition plate 21, a torsion spring 29, a cam crankshaft 2211, a bearing 2212 and an intermediate piece 222. One end of the torsion spring 29 is connected to the housing 1 and the other end of the torsion spring 29 is connected to the intermediate member 222 so that the intermediate member 222 can rotate about the spring center of the torsion spring 29 by an external force. One end of the intermediate member 222 is connected to the transition hole cover 21, and the other end of the intermediate member 222 is detachably contacted with the bearing 2212, that is, when the bearing 2212 moves to a specific position, the intermediate member 222 can be contacted with the bearing 2212, and when the bearing 2212 continues to move for a certain distance, the intermediate member 222 is separated from the contact with the bearing 2212.

In practical applications, by adjusting the position relationship between the intermediate piece 222 and the torsion spring 29, when the intermediate piece 222 is out of contact with the bearing 2212, the intermediate piece 222 can rotate around the spring center of the torsion spring 29 to approach the transition hole 113 under the action of the torque generated by the torsion spring 29, and then the intermediate piece 222 will drive the transition hole cover plate 21 to rotate around the spring center of the torsion spring 29, and finally the transition hole cover plate 21 abuts against the transition hole 113, so as to shield the transition hole 113. It should be noted that when the transition escutcheon plate 21 abuts the transition orifice 113, the torsion spring 29 still applies a force to the intermediate piece 222 tending to rotate, which force is transmitted to the transition escutcheon plate 21, such that the transition escutcheon plate 21 also tends to move in a direction approaching the transition orifice 113, and the cross-sectional area of the transition escutcheon plate 21 is greater than the cross-sectional area of the transition orifice 113, such that the transition orifice 113 will block the movement of the transition escutcheon plate 21, and the transition escutcheon plate 21 will remain stationary and completely close the transition orifice 113 under the combined action of the transition orifice 113 and the torsion spring 29.

For convenience of description, the position of the intermediate member 222 in the casing 1 when the transition hole cover 21 abuts the transition hole 113 is referred to as a starting position.

In this embodiment, the output shaft of the first drive 23 is connected to the cam crankshaft 2211, while the bearing 2212 is connected to the cam crankshaft 2211. The cam crankshaft 2211 can make a circular motion under the driving of the first driving device 23, and when the cam crankshaft 2211 makes a circular motion under the action of the first driving device 23, the cam crankshaft 2211 can simultaneously drive the bearing 2212 to make a circular motion. The intermediate member 222 is at least partially positioned within the circumferential range of motion of the bearing 2212 such that when the bearing 2212 is moved into position, the intermediate member 222 can contact the bearing 2212, and for ease of description, the configuration of the intermediate member 222 within the circumferential range of motion of the bearing 2212 will be referred to as a protrusion.

It should be noted that the rotation direction of the bearing 2212 in the circular motion is clockwise with reference to the view shown in fig. 10, so that when the bearing 2212 contacts with the extension, the bearing 2212 can drive the middle piece 222 to rotate counterclockwise from the starting position, thereby opening the transition hole 113.

When the bearing 2212 makes a circular motion, the bearing 2212 has a circle center position, in practical application, the bearing 2212 can be in contact with the extending part at a specified position by adjusting the position relationship between the extending part and the circle center, and the opening and closing angle of the transition hole cover plate 21 when the transition hole 113 is opened can be controlled by combining the parameters (such as the torsion direction, the torsion force, the maximum deflection, the free length and the like) of the torsion spring 29 and the distance between the circle center and the transition hole 113 when the bearing 2212 makes the circular motion.

Further, by adjusting the size of the protrusion, and combining the angular velocity of the bearing 2212 during circular motion, the contact time between the bearing 2212 and the protrusion can be controlled, and the duration of the transition hole 113 opening by the transition hole cover 21 can be controlled.

Optionally, the recycling aid assembly 2 further comprises a limit sensor 30, wherein the limit sensor 30 is located in the circular motion range of the bearing 2212 and is in separable contact with the bearing 2212, that is, when the bearing 2212 rotates to a specific position, the bearing 2212 will be in contact with the limit sensor 30, and when the bearing 2212 continues to rotate for a certain angle, the bearing 2212 will be out of contact with the limit sensor 30. When the bearing 2212 is in contact with the limit sensor 30, the limit sensor 30 may be triggered to send an electrical signal to the controller in the recovery device a.

The operation principle of the recovery sub-unit 2 in the present embodiment will be described with reference to fig. 10 and 11.

As shown in fig. 10, the intermediate member 222 is located at the starting position, the bearing 2212 is located at a position not contacting with the protruding portion, the transition hole cover plate 21 is kept at a static state under the cooperation of the transition hole 113 and the torsion spring 29, and the transition hole cover plate 21 completely closes the transition hole 113.

When the controller in the recovery device a starts the first driving device 23, the first driving device 23 drives the cam crankshaft 2211 to start clockwise circular motion, and further drives the bearing 2212 to start clockwise circular motion. When the bearing 2212 rotates to the specific position, the bearing 2212 will contact with the protruding part, and as the bearing 2212 continues to rotate, the bearing 2212 will apply a force to the protruding part, and when the force is larger than the torque applied to the intermediate member 222 by the torsion spring 29, the intermediate member 222 will start to rotate counterclockwise, in other words, the counterclockwise rotation of the intermediate member 222 is provided by the bearing 2212. When the intermediate piece 222 rotates counterclockwise, the intermediate piece 222 drives the transition hole cover plate 21 to rotate counterclockwise synchronously, so that the transition hole cover plate 21 and the cover plate sealing ring 25 move in a direction away from the transition hole 113, and finally the transition hole 113 is opened.

When the bearing 2212 rotates clockwise to the position shown in fig. 11, the opening angle between the transition hole cover plate 21 and the transition hole 113 reaches the maximum, the bearing 2212 will be out of contact with the protruding portion, the bearing 2212 will not be able to apply any further force to the protruding portion, and therefore the middle piece 222 will rotate clockwise under the action of the torsion spring 29. When the intermediate piece 222 rotates clockwise, the intermediate piece 222 drives the transition hole cover plate 21 and the cover sealing ring 25 to synchronously rotate clockwise, so that the transition hole cover plate 21 and the cover sealing ring 25 move towards the direction close to the transition hole 113, and finally the transition hole 113 is closed, and the intermediate piece 222 returns to the starting position.

During the process of returning the intermediate member 222 to the starting position, the first driving device 23 continues to operate, so that the bearing 2212 continues to rotate clockwise. When the bearing 2212 rotates to a position in contact with the limit sensor 30, the limit sensor 30 is triggered and the limit sensor 30 will send an electrical signal to the controller in the recovery device a. When the controller receives the electrical signal, the controller may control the first driving device 23 to stop working, so that the bearing 2212 stops rotating, the middle piece 222 is located at the starting position, and the transition hole 113 is closed by the transition hole cover 21 and the cover sealing ring 25.

When the first driving device 23 stops working for a certain period of time, the controller may control the first driving device 23 to start working again, and then the bearing 2212 will start rotating clockwise again, and when the bearing 2212 rotates to a certain angle, the bearing 2212 will be out of contact with the limit sensor 30.

As bearing 2212 continues to rotate, bearing 2212 will again contact the extension, thereby driving the middle piece 222 to rotate counterclockwise from the starting position to begin the next cycle of motion.

It should be noted that during the period of time when the first driving device 23 is deactivated, the suction device in the recovery device a is not deactivated, but always performs the suction operation, thereby changing the air pressure difference across the transition hole 113. In practical application, by adjusting the time length of the first driving device 23 stopping working, the air pressure difference between the two sides of the transition hole 113 can be controlled, so as to achieve better air flow flushing effect, and avoid the problem that the recovery device a breaks down due to overlarge load of the air suction device.

It should be noted that the present embodiment mainly relates to the modification of the recovery auxiliary assembly 2, and the specific structures of other components in the recovery device a, such as the housing 1, the airflow channel 11, the floor brush holder 1011, the trigger probe 1012, the recovery tank 3, etc., can be referred to the related contents in the foregoing embodiments, and will not be described again here.

When the second driving device 5 is of a cam structure or an eccentric wheel structure, the second driving device 5 may be disposed inside the floor brush holder 1011 and located near the second opening 111 in the floor brush holder 1011, the second driving device 5 is connected to an output shaft of the driving motor 50, and the driving motor 50 may drive the second driving device 5 to move, so that the cutting member 4 connected to the second driving device 5 reciprocates in a direction parallel to the axial direction of the rolling brush B31. It should be noted that the axial direction parallel to the rolling brush B31 in the present application is determined by the positional relationship of the rolling brush B31 with respect to the floor brush holder 1011 when the floor brush mechanism B3 is placed on the floor brush holder 1011.

The second driving means 5 may also be a linear reciprocating motor which may be provided inside the floor brush base 1011 and arranged in an axial direction parallel to the roll brush B31 and to which the cutter 4 is connected, and by which the cutter 4 is linearly reciprocated in the axial direction of the roll brush B31.

When the second driving means 5 moves, the cam 51 may slide in the cam guide groove 412, and then the comb 41 may be driven to reciprocate linearly in the axial direction of the roller brush B31, and the cutting edges at both sides of the comb teeth 411 may cut off the hairs wound around the roller brush B31. It should be noted that the comb teeth 411 on the comb 41 may also be configured as a single-sided cutting edge, and the cam structure may refer to the existing linear reciprocating mechanism, which is not described herein in detail.

Referring to fig. 15 and 16, in an embodiment, the comb guide 42 has a plurality of cutting teeth 421 protruding outwards, the sliding groove 414 of the comb 41 has a notch 413, the notch 413 is configured such that when the comb 41 is sleeved on the comb guide 42, the cutting teeth 421 of the comb guide 42 can protrude from the notch 413, and the cutting teeth 421 protruding from the notch 413 are tightly attached to the comb teeth 411. Since the comb 41 can reciprocate along the comb guide 42 and the comb guide 42 is fixed in the floor brush holder 1011, when the comb 41 reciprocates along the comb guide 42 by the second driving means 5, the comb teeth 411 and the cutter 421 can make an alternate motion, and a shearing force can be formed between the comb teeth 411 and the cutter 421 to further improve the cutting effect of the comb teeth 411 on the hair wound on the roll brush B31.

Thus, the roller brush B31 and the cutter 4 can be operated simultaneously, and the cutter 4 can cut off all the hairs entangled on the surface of the roller brush B31 as the roller brush B31 rotates, and the cut hairs will fall off the roller brush B31 and eventually be sucked away by the cleaning device B.

It should be noted that when the floor brush motor in the floor brush mechanism B3 is started, the vacuum source in the cleaning device B may not be activated, and the suction device in the recovery device a may be activated. Thus, the hair falling off the roller brush B31 is sucked into the recovery tub 3 by the recovery device a.
