[0055] See also Figure 1 and Figure 17The present invention provides a garbage collection base station 1000 and a cleaning system 2000 including the garbage collection base station 1000. The cleaning system 2000 includes the garbage collection base station 1000 and a cleaning robot 2100. The cleaning robot 2100 can be a sweeping robot, a sweeping and mopping robot, a mopping robot, a handheld vacuum cleaner, a push-type cleaning machine, or even a ride-on cleaning machine. This embodiment uses the cleaning robot 2100 as a sweeping robot for illustration.

[0056] The cleaning robot 2100 includes a main body, on which a cleaning structure is provided. The cleaning structure can be a sweeping component, a mopping component, a roller brush component, or a combination of any two or more of these components. The cleaning structure is mainly used to automatically clean the cleaning area. The cleaned dust, hair, paper scraps and other garbage are collected through the dust collection chamber inside the cleaning robot 2100. The main body of the cleaning robot 2100 is provided with a dust discharge port connected to the dust collection chamber, and the dust discharge port is used to discharge the collected materials in the dust collection chamber.

[0057] Garbage collection base station

[0058] See also Figure 1 、 Figure 6 、 Figure 7 and Figure 17 The garbage recycling base station 1000 includes a base station body 100, a fan 200, a dust collection component 300, a sensor 700, a dust full detection device 10 and a controller 800, etc.

[0059] See also Figure 8 and Figure 17 The waste collection base station 1000 includes a base station body 100, which is equipped with a carrying portion 101 for carrying a cleaning robot 2100. When the cleaning robot 2100 needs to discharge collected materials, charge, or store them after use, it can move to the carrying portion 101 for parking. The carrying portion 101 is provided with a dust collection port, which can be connected to the dust discharge port of the cleaning robot 2100. The cleaning robot 2100 discharges collected materials into the waste collection base station through the dust discharge port for collection.

[0060] The shape of the base station body is not specifically limited, and can be regular or irregular. For the convenience of description, the base station body is roughly L-shaped for explanation. Figure 1 、 Figure 8 and Figure 17The carrying portion 101 of the garbage collection base station 1000 is located in a lower position, and the upper surface of the carrying portion 101 serves as a carrying area for carrying the cleaning robot 2100. The carrying area is provided with a front wheel positioning groove 102 for placing the front wheels of the cleaning robot 2100, and a rear wheel positioning groove 103 for placing the rear wheels of the cleaning robot 2100. In particular, in the direction in which the cleaning robot 2100 drives onto the carrying portion 101, the groove width of the front wheel positioning groove 102 gradually decreases, which guides the movement of the front wheels. A charging electrode 104 is provided on the carrying portion 101. When the cleaning robot 2100 is parked on the carrying portion 101, the cleaning robot 2100 can be charged through the charging electrode 104.

[0061] The base station body 100 is an installation carrier, which has a support structure fixed to the ground, a carrying part 101 that docks with the cleaning robot 2100, and a structure for installing various electronic components. The base station body 100 can be made of metal, ceramics, plastic, wood and other materials.

[0062] See also Figure 3 The base station body 100 is provided with a dust inlet channel 110 and an air extraction channel 140 and a receiving chamber 120 connected to the dust inlet channel 110 and the air extraction channel 140, and the receiving chamber 120 has a cavity opening open to the outside. The dust inlet channel 110 and the air extraction channel 140 can be pipes extending from the base station body 100 to the receiving chamber 120, or can be pipes extending from the base station body 100 to the outside. The shape of the dust inlet channel 110 and the air extraction channel 140 can be a circular tube, a square tube or a through tube of other shapes, which are not specifically limited here. The shape of the receiving chamber 120 can be a cubic cavity, a cylindrical cavity or a cavity of other shapes, and the shape of the cavity opening of the receiving chamber 120 can be a circular cavity opening or a square cavity opening, etc. It can also be a cavity opening of other shapes, which are not listed here one by one. The opening of the accommodating cavity 120 can be located on any one of the front, back, side, or top surfaces of the base station body 100, so that the dust collection component 300 can extend or retract from the front, back, side, or top surface of the base station body 100.

[0063] See also Figure 1 and Figure 3The fan 200 is fixed to the base station body 100 and pneumatically connected to the exhaust channel 140. The fan 200 is an existing device with an air intake and an air outlet, such as a blower, ventilator, centrifugal fan, etc., which can generate suction at the air intake to draw in air and discharge the inhaled air through the air outlet. The fan 200 can be installed on the outer wall of the base station body 100, or it can be installed in another cavity within the base station body 100 that is separated from the receiving cavity 120. The fan 200 only needs to ensure that its air intake is connected to the exhaust channel 140 of the base station body 100 and its air outlet is connected to the outside world.

[0064] See also Figure 1 and Figure 3 The dust collecting component 300 can extend from the cavity mouth or retract into the receiving cavity 120. The dust collecting component 300 can extend from the receiving cavity 120 and be disconnected from the dust inlet channel 110 and the air exhaust channel 140. The dust collecting component 300 can be retracted and installed in the receiving cavity 120 and be sealed and connected with the dust inlet channel 110 and the air exhaust channel 140.

[0065] The dust collecting component 300 can adsorb or intercept dust, garbage, etc. in the air entering the receiving chamber 120, and finally achieve air filtration. The sealed connection between the dust collecting component 300 and the dust inlet channel 110, and the sealed connection between the dust collecting component 300 and the air extraction channel 140 can be accurately docked by setting the positions of the ports of the dust inlet channel 110 and the air extraction channel 140, the shape and position of the cavity opening of the receiving chamber 120, and the shape of the dust collecting device. A docking structure can be provided at the docking point between the dust collecting component 300 and the dust inlet channel 110 and the air extraction channel 140 to enhance the sealing of the docking, such as mutually buckled snap rings. The buckling of the snap rings enhances the stability of the docking and ensures good sealing; for example, by adding other deformable components, they can be squeezed and deformed to fit tightly together, thereby enhancing the sealing effect.

[0066] See also Figure 6 and Figure 7 , the sensor 700 detects whether the dust collecting component 300 is installed in the preset position in the receiving chamber 120. The sensor 700 can be a contact sensor 700 or a non-contact sensor 700; therefore, there are many types of sensors 700 to choose from, such as a pressure sensor, a Hall sensor, a magnetic field sensor or a mechanical contact switch. Specifically, the magnetic field sensor can be installed on the base station body 100 to detect the distance between the dust collecting component 300 and its corresponding preset position. It should be noted that the preset position refers to the position where the dust collecting component 300 is received in the receiving chamber 120, and is connected to the dust inlet channel 110 and the exhaust channel 140, and can seal the opening of the receiving chamber 120.

[0067] The controller 800 is electrically connected to the sensor 700. The controller 800 can be a computer or a PLC device. It can receive signals from the sensor 700 and control the working state of the fan 200 according to the signals from the sensor 700. For example, when the sensor 700 detects that the dust collecting component 300 has left its preset position, the dust collecting component 300 is no longer connected to the dust inlet channel 110 and the air extraction channel 140. The controller 800 controls the fan 200 to stop working upon receiving the detection result. When the dust collecting component 300 is detected to be in the preset position, the dust collecting component 300 is connected to the dust inlet channel 110 and the air extraction channel 140. After receiving the detection result, the controller 800 can control the fan 200 to start working according to the dust collection signal to complete the garbage collection function. The controller 800 can receive the signal from the sensor 700 through wireless transmission, such as Bluetooth, Wi-Fi, etc., or through a wired connection to transmit and receive signals. Of course, the controller 800 can also control other devices electrically connected to it, such as motors and other electrically controllable devices. The controller 800 can also add components such as switches that are manually controlled.

[0068] By providing a receiving cavity 120 with an open cavity on the base station body 100 of the garbage recycling base station 1000, a dust collecting component 300 is provided which can extend out of the receiving cavity 120 through the cavity or be received into the receiving cavity 120, thereby realizing a drawer-like removal and storage method for the dust collecting component 300 that needs to be cleaned, thereby facilitating the cleaning of the dust collecting component 300. At the same time, when the dust collection assembly 300 extends out of the receiving chamber 120, it is disconnected from the dust inlet channel 110 and the air extraction channel 140. When the dust collection assembly 300 is retracted into the receiving chamber 120, it is sealed and connected to the dust inlet channel 110 and the air extraction channel 140. A sensor 700 is further provided to detect whether the dust collection assembly 300 is installed in a preset position within the receiving chamber 120. This ensures that the dust collection assembly 300 is properly installed in the receiving chamber 120 when retracted, so that the dust collection assembly 300 is accurately connected to the dust inlet channel 110 and the air extraction channel 140, preventing garbage and dirt from leaking out of the receiving chamber 120 during operation of the garbage collection base station 1000, which increases the difficulty of cleaning. A controller 800 is provided to receive signals from the sensor 700 and control the operating status of the fan 200, further improving the intelligence of the garbage collection base station 1000.

[0069] In one embodiment, see Figure 1 and Figure 4aThe dust collection assembly 300 includes a supporting body 310 and a dust bag 320. The supporting body 310 is retractably mounted in the receiving chamber 120. The supporting body 310 is provided with a receiving chamber 311, and the receiving chamber 311 has an externally open mounting opening 312. The mounting opening 312 is perpendicular to the direction of extension and contraction of the supporting body 310. The dust bag 320 is received in the receiving chamber 311 through the mounting opening 312. The supporting body 310 drives the dust bag 320 to extend or retract into the receiving chamber 120, facilitating its removal and cleaning. The supporting body 310 can be made of a relatively rigid material, such as metal or plastic, so that it is not easily deformed, which helps to support the dust bag 320 and prevent it from falling off.

[0070] Among them, the carrying body 310 can be separated from the receiving chamber 120, so as to facilitate the removal of the dust collecting component 300 for dumping garbage; or, the carrying body 310 and the receiving chamber 120 are inseparable, the dust collecting component 300 is extended a certain distance from the receiving chamber 120, and then the dust collecting bag 320 is taken out to dump garbage.

[0071] The supporting body 310 with the mounting opening 312 has various shapes, such as a drawer box shape with one side open, or a ring box shape with two opposite sides open. The supporting body 310 can also have other shapes, and it only needs to have a storage cavity 311 to meet the needs of supporting and fixing the dust bag 320.

[0072] The dust bag 320 can be a soft filter bag alone, or it can be a combination of a supporting frame and a soft filter bag. The dust bag 320 can be made of a variety of materials, such as water-repellent and linoleum-proof felt, polyester needle-punched felt, and triple-proof polyester needle-punched felt. Preferably, the dust bag 320 is made of water-repellent and linoleum-proof felt, which has a dense weave, good particle retention, and excellent dust filtration performance.

[0073] Furthermore, in order to enhance the sealing performance between the carrier body 310 and the cavity opening of the receiving cavity 120, please refer to Figure 4a and Figure 5 The carrying body 310 is provided with a top plate 313 and a bottom plate 314 arranged opposite to the top plate 313, and a sealing ring 313a installed on the peripheral side of the top plate 313. A receiving cavity 311 is provided between the top plate 313 and the bottom plate 314. When the carrying body 310 is retracted into the receiving cavity 120, the top plate 313 covers the cavity opening, and the sealing ring 313a is sealed between the top plate 313 and the peripheral side wall of the receiving cavity 120.

[0074] The sealing ring 313a can be a hard or soft structure. When a hard structure is selected, it is generally fastened or fitted with the structure provided around the opening of the receiving cavity 120 to achieve a sealing effect. For example, the opening of the receiving cavity 120 is surrounded by a groove, and the sealing ring 313a is a raised ring that adapts to the groove. When a soft structure is selected for the sealing ring 313a, it can be made of rubber, soft plastic, silicone, etc., so that it can be squeezed between the top plate 313 and the opening of the receiving cavity 120 and deform, thereby blocking the surrounding gap to ensure a sealing effect. The number of sealing rings 313a can be one or more, and is not specifically limited here.

[0075] To enhance the sealing and the stability of the connection between the carrier body 310 and the receiving cavity 120, please refer to Figure 1 and Figure 2 , at least one card slot 121 is formed on the cavity wall of the receiving cavity 120; the garbage collection base station 1000 also includes at least one active card buckle 400 and an elastic reset switch 500, and several active card buckles 400 are movably installed on the carrying body 310; the elastic reset switch 500 is installed on the side of the carrying body 310 opposite to the bottom of the receiving cavity 120, and it acts on several active card buckles 400 to switch several active card buckles 400 between a locked position and an unlocked position, wherein the active card buckle 400 is engaged with the card slot 121 in the locked position, and the active card buckle 400 is separated from the card slot 121 in the unlocked position.

[0076] The position of the card slot 121 can be close to the cavity opening of the receiving cavity 120, or it can be not close to the cavity opening of the receiving cavity 120. The shape of the card slot 121 can be a groove that is vertically recessed perpendicular to the cavity wall of the receiving cavity 120, or it can be a groove recessed at other angles to the cavity wall of the receiving cavity 120, such as 60° or 80°. The card slot 121 can be a strip groove, a circular groove or a groove of other shapes without specific restrictions. Of course, the shape of the end of the movable buckle 400 close to the card slot 121 is adapted to the shape of the card slot 121. The elastic reset switch 500 can be a structure composed of plastic, rubber, spring or a combination of such elastic materials.

[0077] To ensure the stable and smooth operation of the active buckle 400, please refer to Figure 5 A surface of the carrier body 310 away from the bottom of the accommodating cavity 120 is provided with a clearance groove 340 and at least one guide channel 360 connected to the clearance groove 340. At least one movable buckle 400 is movably installed in the corresponding at least one guide channel 360, and the elastic reset switch 500 is connected to the end of at least one movable buckle 400 extending into the clearance groove 340.

[0078] The shape of the give way groove 340 can be a strip groove, a square groove or a groove of other shapes. The shape of the guide channel 360 connected to the give way groove 340 is adapted to the shape of the movable buckle. The inner wall of the guide channel 360 can be additionally provided with an oil guide groove connected to the limit groove to facilitate the addition of lubricating oil into the guide channel 360, so as to improve the smoothness of the cooperation between the movable buckle and the guide channel 360.

[0079] Further, see Figure 1 and Figure 2 The at least one latching slot 121 includes two latching slots 121 disposed opposite each other, the at least one movable buckle 400 includes two movable buckles 400 disposed opposite each other, the at least one guide channel 360 includes two guide channels 360 disposed opposite each other, the clearance groove 340 is located between the two guide channels 360, and the elastic reset switch 500 includes two elastic arms 510 disposed in parallel and a connecting arm 520 connecting the two elastic arms 510. The two elastic arms 510, located away from the connecting arm 520, are respectively connected to the ends of the movable buckles 400 on the corresponding sides. This arrangement further strengthens the secure fit between the carrier body 310 and the receiving cavity 120 and facilitates the application of force by the elastic reset switch 500 to the movable buckle 400.

[0080] The elastic arm 510 is a structure that can deform under stress. This deformation drives the movable buckle 400 to move, thereby controlling whether the movable buckle 400 is engaged with the slot 121. The elastic arm 510 can be made of a variety of materials, such as metal, plastic, or rubber. It is worth noting that thinner metal plates, such as thin iron or aluminum plates, are more susceptible to deformation under stress. The connecting arm 520 can be made of the same material as the elastic arm 510, or a different material. The connecting arm 520 and the elastic arm 510 can be integrally formed, or they can be manufactured separately and connected together by bolting, riveting, or welding.

[0081] To prevent the elastic arm 510 from being insufficiently elastic or losing its elasticity due to long-term use, which may result in the movable buckle 400 being unable to be reset, please refer to Figure 5 The elastic reset switch 500 also includes a reset spring 530 located within the clearance groove 340 and elastically connected to the two movable clips 400. The ends of the two movable clips 400 extending into the clearance groove 340 are each provided with a snap-fitting protrusion 410. The two snap-fitting protrusions 410 are mounted between two elastic arms 510. Under the action of the reset spring 530 on the movable clip 400, the two snap-fitting protrusions 410 engage with the corresponding elastic arms 510. This spring is a compression spring, and the materials and processing techniques used in conventional springs are all within the scope of protection of the present invention.

[0082] In one embodiment, see Figure 4bThe dust collection assembly 300 includes a dust collection body 301, which is retractably mounted in the receiving chamber 120. The dust collection body 301 is provided with an air inlet 301a corresponding to the dust inlet channel 110 and a filter 301b corresponding to the exhaust channel 140, as well as a dust collection chamber 301c connecting the air inlet 301a and the filter 301b. The dust collection chamber 301c is connected to the dust inlet channel 110 via the air inlet 301a, and the dust collection chamber 301c is connected to the exhaust channel 140 via the filter 301b. The filter 301b can be a device with a filtering structure such as cloth fabric, metal fabric, or HEPA, which can be connected to the exhaust channel 140 so that clean air filtered by it can be extracted. The shape and size of the filter 301b can be customized as needed. In one embodiment, the filter 301b is a filter bag, that is, the filter 301b has an air inlet 301a and a dust collection chamber 301c. The filter 301b is fixed to the carrier body 301. The filter 301b and the carrier body 301 can be separated from the receiving chamber 120 together to dump waste. The carrier body 301 or the filter 301b can be provided with a flap, which can be opened to dump waste. In another embodiment, the filter 301b is a filter screen, and the carrier body 301 has an air inlet 301a and a dust collection chamber 301c.

[0083] In one embodiment, see Figure 3 The receiving chamber 120 has a cavity opening 122 and a cavity bottom 123 that are arranged relatively to each other. The cross-sectional area of the receiving chamber 120 is gradually reduced from the cavity opening 122 to the cavity bottom 123. The shape of the dust collecting component 300 is adapted to the shape of the receiving chamber 120. Such an arrangement enables the dust collecting component 300 to be fitted with the inner wall of the receiving chamber 120 to prevent leakage of air containing dirt. Moreover, the dust collecting component 300 and the inner wall of the receiving chamber 120 are matched in an inclined surface, which can reduce the mutual friction between the two during the process of the dust collecting component 300 extending or being retracted into the receiving chamber, thereby reducing its loss. The matching of the inclined surface also has a certain centering effect, which can make the dust collecting component 300 more accurately docked with the dust inlet channel 110 and the air extraction channel 140, thereby ensuring good sealing of the garbage collection base station 1000.

[0084] In one embodiment, see Figure 1 、 Figure 2 and Figure 5The dust collecting assembly 300 is provided with two elastic plates 330 arranged in parallel on one side of the bottom of the receiving chamber 120. The surfaces of the two elastic plates 330 facing the wall of the receiving chamber 120 are both provided with stop protrusions 331. The wall of the receiving chamber 120 adjacent to the cavity opening 122 is correspondingly provided with two mating protrusions 130, which can mate with the corresponding stop protrusions 331. This arrangement can limit the position of the dust collecting assembly 300. When the dust collecting assembly 300 moves away from the receiving chamber 120, the stop protrusions 331 and the mating protrusions 130 form a locking position to prevent the dust collecting assembly 300 from continuing to move. This can ensure that the dust collecting assembly 300 remains extended relative to the receiving chamber 120, making it easier for the user to remove the dust bag of the dust collecting assembly 300 and preventing the operator from using excessive force and completely pulling the dust collecting assembly 300 out of the receiving chamber 120. However, when it is necessary to remove the dust collecting component 300, a greater force is applied to the dust collecting component 300, and the mating protrusion 130 will squeeze the stop protrusion 331, or the elastic plate 330 can be directly applied with force to drive the elastic plate 330 to deform in a direction away from the mating protrusion 130, so that the stop protrusion 331 can move to the top of the mating protrusion 130.

[0085] The elastic plate 330 can be made of a variety of materials, such as metal, plastic, or rubber. Each elastic plate 330 can have one or more stop protrusions 331. The number of mating protrusions 130 on the inner wall of the receiving cavity 120 opposite the elastic plate 330 corresponds to the number of stop protrusions 331. The stop protrusions 331 and the mating protrusions can be round, bar-shaped, or other shapes, without specific limitation.

[0086] In one embodiment, see Figure 2 and Figure 5 Each of the two elastic plates 330 is provided with a clearance hole 332. The garbage collection base station 1000 further includes a movable lock 600, which includes two movable plates 610 and an elastic return member 620. One end of each movable plate 610 extends from the corresponding clearance hole 332. The two ends of the elastic return member 620 are respectively connected to the ends of the two movable plates 610 away from the corresponding clearance hole 332 to elastically support the two movable plates 610. This arrangement allows the dust collection assembly 300 to have a fixed position extending out of the receiving chamber 120, freeing the operator's hands and facilitating the cleaning of dust and dirt.

[0087] When the dust collecting assembly 300 is moved away from the receiving chamber 120, the two movable plates 610 are squeezed by the mating protrusion 130 and shrink toward each other. When the two movable plates 610 move to above the mating protrusion 130 and are no longer squeezed, the two movable plates 610 extend back due to the action of the elastic reset member 620. When the force applied to the dust collecting assembly 300 away from the receiving chamber 120 is removed, due to the action of gravity, the two movable plates 610 abut against the mating protrusion 130 to form a locking position, thereby fixing the position of the dust collecting assembly 300.

[0088] It should be noted that the clearance hole 332 can be a circular hole, a square hole or a hole of other shapes, and the end of the movable plate 610 adjacent to the clearance hole 332 is adapted to the shape of the clearance hole 332. The elastic return member 620 can be a spring, or it can be an elastic rubber component.

[0089] In one embodiment, see Figure 2 and Figure 5 The movable plate 610 includes a first section 611 and a second section 611 connected in sequence. The width of the first section 611 is smaller than that of the second section 611. The first section 611 is loosely fitted with the clearance hole 332. The end of the second section 611 adjacent to the first section 611 abuts against the elastic plate 330, and the end of the second section 611 away from the first section 611 is connected to the elastic return member 620. This arrangement allows for precise control of the travel of the movable plate 610 and prevents the elastic return member 620 from causing damage to the inner wall of the receiving chamber 120 when the movable plate 610 is reset.

[0090] The second section 611 can be wider than the first section 611 as a whole or wider than the first section 611 by protruding on one side. The second section 611 can be connected to the elastic reset element 13a by detachable snap connection or fixed connection by welding.

[0091] In one embodiment, see Figure 5 The surface of the dust collection assembly 300, away from the opening 122 of the receiving chamber 120, further includes projecting pivoting platforms 350 positioned opposite each other. The two pivoting platforms 350 are located between the two elastic plates 330 and are pivotally connected to the center of the corresponding movable plate 610. This arrangement enhances the stability of the connection between the movable lock 600 and the dust collection assembly 300. The pivoting platform 350 and the movable plate 610 can be a rigid connection via a plug-in shaft or a flexible connection via a hinge, as long as it provides a secure connection to the movable lock 600 without hindering its movement.

[0092] In one embodiment, see Figure 6 and Figure 7In order to make the garbage collection base station 1000 more automated and intelligent, the garbage collection base station 1000 also includes a lifting mechanism 900. The lifting mechanism 900 is installed on the base station body 100. The lifting mechanism 900 is connected to the dust collecting component 300 to drive the dust collecting component 300 to rise and fall.

[0093] The lifting mechanism 900 includes a gear 910, a rack 920, and a motor 930. The rack 920 is mounted on the outer surface of the dust collection assembly 300 and extends along the bottom 123 of the receiving chamber 120 toward the opening 122 of the receiving chamber 120. The motor 930 is mounted on the base station body 100. The gear 910 is connected to the output shaft of the motor 930. The gear 910 is entirely or partially located within the receiving chamber 120 and is meshed with the rack 920. In other embodiments, the lifting mechanism 900 may also be in the form of a screw thread mechanism, a connecting rod mechanism, or the like.

[0094] Of course, the motor 930 of the lifting device can also be electrically connected to the controller 800, and the position of its movement can be detected by the sensor 700 to achieve its automatic operation.

[0095] Dust full detection device

[0096] See also Figure 1 and Figure 9 The waste collection base station 1000 also includes a dust full detection device 10. The dust full detection device 10 is fixed to the base station body 100 and is used to detect whether the dust collection assembly 300 meets the preset dust full condition and generate a dust full signal when the dust collection assembly 300 meets the preset dust full condition. The controller 800 of the waste collection base station 1000 is electrically connected to the dust full detection device 10 and the fan 200. The controller 800 is used to receive the dust full signal from the dust full detection device 10 and control the fan 200 to stop operating based on the dust full signal from the dust full detection device 10.

[0097] In addition, the controller 800 is electrically connected to the dust full detection device 10. The controller 800 is further configured to control the lifting mechanism 900 to drive the dust collection assembly 300 to rise when receiving a dust full signal from the dust full detection device 10. Thus, on the one hand, the controller 800 can control the fan 200 to stop operating when the sensor 700 detects that the dust collection assembly 300 has left a preset position within the receiving chamber 120, thereby promptly shortening the dust extraction time. On the other hand, the user can intuitively know from the raised dust collection assembly 300 that the dust collection assembly 300 is full of garbage and needs to be dumped.

[0098] Specifically, when the controller 800 receives the dust full signal, it sends an instruction to start the motor 930 in the lifting mechanism 900 to control the output shaft of the motor 930 to rotate, and the gear 910 connected to the output shaft of the motor 930 rotates accordingly. The rotating gear 930 cooperates with the corresponding meshing rack 920 to drive the dust collecting component 300 fixedly connected to the rack 920 to rise. After the dust collecting component 300 rises, it extends out of the receiving cavity 120 to facilitate the operator to clean it.

[0099] In the above description of the dust collecting assembly 300, the dust collecting assembly 300 may include a carrying body 310 and a dust collecting bag 320 (e.g. Figure 15 As shown, the carrier body 310 is provided with a storage cavity 311, and the dust bag 320 is installed in the storage cavity 311 to collect waste. Alternatively, the dust collection assembly 300 includes the dust collection body, and the dust collection cavity is directly provided in the dust collection body to collect waste. The following mainly explains the preferred dust collection assembly 300 including the carrier body 310 and the dust bag 320.

[0100] Whether the preset dust full condition is met can be understood as follows:

[0101] When the dust collecting assembly 300 continuously absorbs collected material and the total weight of the collected material continuously increases, when the weight exceeds a certain preset weight value, the dust collecting assembly 300 can be considered to have met the preset dust full condition. Alternatively, when the dust collecting assembly 300 continuously absorbs collected material, causing the air flow resistance within the dust collecting assembly 300 to increase, thereby significantly reducing the dust suction force within the dust inlet channel 110, the dust collecting assembly 300 can be considered to have met the preset dust full condition.

[0102] The means for detecting whether the dust collecting assembly 300 meets the preset dust full condition are:

[0103] A weight determination method is used. If the dust-full detection device 10 is a pressure detection device, the pressure detection device is installed in the storage cavity 311, and the pressure detection device is used to sense the weight of the dust bag 320. A weight threshold is preset in the pressure detection device. When the weight sensed by the pressure detection device is greater than the threshold, the pressure detection device sends a dust-full signal to the controller 800. The controller 800 is installed on the base station body 100. The controller 800 is electrically connected to the pressure detection device and the fan 200 at the same time. When the controller 800 receives the dust-full signal from the pressure detection device, the controller controls the fan 200 to stop working. The electrical connection between the components can be a wire connection or a wireless connection.

[0104] The judgment method adopts the change of air pressure. Figure 13aFor example, the dust fullness detection device 10 includes a pipe 11, a sensing component 12, and a floating component 13. The pipe 11 has a connecting end 11a and a free end 11b. The connecting end 11a of the pipe 11 is connected to the storage chamber 311, and the free end 11b of the pipe 11 is located away from the storage chamber 311. The sensing component 12 is fixed to the connecting end 11a or the free end 11b of the pipe 11.

[0105] The floating assembly 13 is movably mounted within the duct 11 and can move between the connection end 11a and the free end 11b in response to changes in air pressure within the storage chamber 311. When the dust bag 320 meets a preset dust full condition, the floating assembly 13 responds to the negative pressure within the storage chamber 311 and moves closer to the connection end 11a relative to the sensing assembly 12, triggering the sensing assembly 12 to generate a dust full signal. In other embodiments, the dust full detection device 10 can also be an air pressure sensor.

[0106] The sensing component 12 may be used in various ways, such as a light sensor, a Hall sensor 12c or a pressure sensor 12d.

[0107] When the dust bag 320 meets the preset dust full condition, the floating assembly 13 moves from the first position to the second position.

[0108] The sensing component 12 includes a light emitter 12a and a light receiver 12b disposed relative to the light emitter 12a. The floating component 13 blocks the light signal between the light emitter 12a and the light receiver 12b in the first position, and does not block the light signal between the light emitter 12a and the light receiver 12b in the second position.

[0109] Alternatively, the sensing component 12 includes a Hall sensor 12c, and the floating component 13 is disposed adjacent to the Hall sensor 12c at the first position and away from the Hall sensor 12c at the second position;

[0110] Alternatively, the sensing component 12 includes a pressure sensor 12d, and the floating component 13 contacts the pressure sensor 12d in the first position and is away from the pressure sensor 12d in the second position.

[0111] Specifically, when the sensing component 12 is a light sensor, please refer to Figure 11, the sensing component 12 includes a light emitter 12a and a light receiver 12b arranged relative to the light emitter 12a. The floating component 13 can be a piston member 131b, or a piston member 131b and a light shield 132b arranged on the piston member 131b. The latter is used in this article. During operation, the floating component 13 has a first position, and the floating component 13 blocks the light signal between the light emitter 12a and the light receiver 12b in the first position. When the dust bag 320 meets the preset dust full condition, the floating component 13 moves to the second position, as shown in FIG. Figure 12 In the second position, the floating component 13 does not block the optical signal between the optical transmitter 12a and the optical receiver 12b.

[0112] When the sensing component 12 includes the Hall sensor 12c, the floating component 13 has a certain degree of magnetism. Figure 13a and Figure 13b In operation, the floating assembly 13 has a first position, in which the floating assembly 13 is adjacent to the Hall sensor 12c. Figure 13a When the dust bag 320 meets the preset dust full condition, the floating component 13 moves from the first position to the second position, and the floating component 13 is set away from the Hall sensor 12c at the second position, as shown. Figure 13b It can be understood that the magnetic flux of the floating component 13 when it is in the first position is greater than the magnetic flux of the floating component 13 when it is in the second position.

[0113] When the sensing component 12 includes a pressure sensor 12d, refer to Figure 14a and Figure 14b In operation, the floating assembly 13 has a first position, in which the floating assembly 13 contacts the pressure sensor 12d. Figure 14a When the dust bag 320 meets the preset dust full condition, the floating component 13 moves from the first position to the second position under the action of negative pressure. The floating component 13 is away from the pressure sensor 12d at the second position. Figure 14b shown.

[0114] The above-described several implementations of the sensing assembly 12 represent technical solutions based on the same concept. Any alternative solutions readily conceivable by those skilled in the art, based on or in accordance with the concepts of the present invention, fall within the scope of protection of this application. Furthermore, in the above-described implementations, after displacement, the floating assembly 13 can be manually reset or automatically reset using a return mechanism. The return mechanism can employ an elastic return element 13a or a drive mechanism. The use of the elastic return element 13a is described in detail below.

[0115] The floating assembly 13 includes an elastic reset element 13a and a floating member 13b. The elastic reset element 13a elastically connects the pipe 11 and the floating member 13b. The elastic reset element 13a provides an elastic force to move the floating member 13b away from the connecting end 11a, so that the floating member 13b moves relative to the sensing assembly 12 in response to a preset negative pressure. The force generated by the preset negative pressure on the floating member 13b is greater than the elastic force.

[0116] The elastic reset element 13a can be a spring or an elastic band. The following specifically illustrates the case where the elastic reset element 13a is a spring and the sensing component 12 is a light sensor 700. Other cases can be referred to accordingly.

[0117] See also Figure 11 A spring is disposed within the pipe 11, with one end of the spring being fixed and the other end being connected to the floating component 13b. During operation, the floating component 13 has a first position, in which the floating component 13 blocks the optical signal between the optical transmitter 12a and the optical receiver 12b. When the dust bag 320 meets a preset dust-filled condition, negative pressure is generated within the storage chamber 311, and the floating component 13b moves toward the connection end 11a of the pipe 11 and compresses the spring, causing the floating component 13 to move to a second position, in which the floating component 13 does not block the optical signal between the optical transmitter 12a and the optical receiver 12b. Subsequently, when the negative pressure within the storage chamber 311 is released, the floating component 13b moves to its initial position under the restoring force of the spring.

[0118] Based on this embodiment, there are several parallel or alternative solutions. For example, the spring can be located outside the free end 11b of the pipe 11; or the spring can be located partially inside the pipe 11 and partially outside the free end 11b of the pipe 11. The fixed end of the spring can be fixed to the connecting end 11a of the pipe 11 or to the free end 11b of the pipe 11, etc.

[0119] In summary, the dust full detection device 10 has been mainly described. However, one thing needs to be mentioned, that is, the communication between the dust full detection device 10 and the storage chamber 311 can be direct or indirect. Direct communication means that the connection end 11a of the pipe 11 is directly connected to the storage chamber 311, and indirect communication means that the connection end 11a of the pipe 11 is connected to the storage chamber 311 through other components, and then through other components. For indirect communication, for example, the above-mentioned exhaust channel 140 is in a connected state with the storage chamber 311, so the connection end 11a of the pipe 11 can be indirectly connected to the storage chamber 311 by connecting the exhaust channel 140. Or as exemplified below, there is a case where an expansion space 30 is provided.

[0120] Dust collection components

[0121] See also Figure 15 The dust collection assembly 300 includes a supporting body 310 and a dust collection bag 320. The supporting body 310 includes a top plate 313, a bottom plate 314 disposed opposite the top plate 313, and a side plate 315 connecting the top plate 313 and the bottom plate 314. The top plate 313, the bottom plate 314, and the side plates 315 enclose a storage chamber 311. The storage chamber 311 has an open installation opening 312, which is oriented perpendicular to the installation or removal direction of the supporting body 310. The connection end 11a of the pipe 11 is connected to the storage chamber 311 through the bottom plate 314, the installation opening 312, or the side plate 315.

[0122] For further information, see Figure 1 、 Figure 9 、 Figure 10 and Figure 16 The garbage collection base station 1000 includes a dust full detection device 10 and a controller 800. The carrying body 310 is provided with a rib structure 20, a first air vent 50 and a second air vent 60 on the inner surface of the storage chamber 311. The rib structure 20 is used to support the dust bag 320 and isolate the dust bag 320 from the first air vent 50 and the second air vent 60. An air flow channel 70 is formed between the rib structures 20. The air flow channel 70 constitutes a part of the storage chamber 311. The first air vent 50 and the second air vent 60 are both connected to the air flow channel 70. The first vent 50 is pneumatically connected to the dust full detection device 10, and the exhaust channel 70 is connected to the storage chamber 311 via the second vent 60. The controller 800 is electrically connected to the dust full detection device 10 and the fan 200, and controls the working state of the fan 200 according to the signal of the dust full detection device 10. The specific structural form of the dust full detection device 10 can be referred to the previous description and will not be repeated here.

[0123] The dust full detection device 10 is used to detect whether the dust collection assembly 300 meets a preset dust full condition and generate a dust full signal when the dust collection assembly 300 meets the preset dust full condition. The controller 800 is used to receive the dust full signal from the dust full detection device 10 and control the fan 200 to stop operating based on the dust full signal from the dust full detection device 10.

[0124] The rib structure 20 can prevent the dust bag 320 from blocking the first vent 50 and the second vent 60 , so that the fan 200 remains in communication with the storage chamber 311 , and the dust full detection device 10 remains in communication with the storage chamber 311 .

[0125] See also Figure 1 、 Figure 9 、 Figure 10 and Figure 16The bottom plate 314 is provided with a rib structure 20, a first vent 50, and a second vent 60 on the surface near the top plate 313. The rib structure 20 is used to support the dust bag 320 and isolate the dust bag 320 from the first vent 50 and the second vent 60. An air flow channel 70 is formed between the rib structures 20. The air flow channel 70 constitutes a part of the storage chamber 311. The first vent 50 and the second vent 60 are both connected to the air flow channel 70. The connecting end 11a of the pipe 11 is connected to the storage chamber 311 through the first vent 50, and the exhaust channel 140 is connected to the storage chamber 311 through the second vent 60. Optionally, the rib structure 20 is arranged radially along the second vent 60. The air flow channel 70 is also used to guide the airflow around the dust bag 320 to the first vent 50, ensuring that the dust bag 320 continues to collect garbage under the action of vacuum.

[0126] In other embodiments, the rib structure 20, the first vent 50 and the second vent 60 may also be disposed at other positions of the carrier body 310 and may be disposed as required.

[0127] For further information, see Figure 10 The bottom plate 314 is recessed on a surface away from the top plate 313 to form an expansion space 30. The expansion space 30 communicates with the first vent 50. The connecting end 11a of the pipe 11 communicates with the receiving chamber 311 via the expansion space 30 and the first vent 50. It will be appreciated that the separate expansion space 30 communicates with the pipe 11, creating a buffer space between the receiving chamber 311 and the pipe 11. This ensures sufficient space outside the connecting end 11a of the pipe 11 to generate sufficient force to move the floating member 13b when negative pressure is generated.

[0128] Furthermore, the rib structure 20 includes a barrier 40 , which covers the first vent 50 , and a gap is provided between the barrier 40 and the first vent 50 .

[0129] In this embodiment, in order to prevent the dust bag 320 from blocking the first vent 50 after expansion and affecting the operation of the dust full detection device 10, the rib structure 20 preferably further includes a barrier member 40 protruding from the bottom plate 314 near the top plate 313. Figure 16 The barrier 40 covers the first vent 50, and a gap is provided between the barrier 40 and the first vent 50. Furthermore, when the dust bag 320 expands, it directly presses against the barrier 40 for support, and a gap exists between the barrier 40 and the first vent 50, thereby ensuring communication between the first vent 50 and the airflow channel 70. In other embodiments, the barrier 40 may also be provided at other locations on the carrier body 310, and can be provided as needed.

[0130] The waste collection base station 1000 of the present invention includes a dust full detection device 10. The dust full detection device 10 detects whether the dust collection assembly 300 meets a preset dust full condition and generates a dust full signal when the dust collection assembly 300 meets the preset dust full condition. This allows the user to clean the dust bag 320 promptly after receiving the dust full signal. Furthermore, upon receiving the dust full signal generated by the dust full detection device 10, the controller disposed in the base station body 100 controls the fan 200 to stop operating, thereby stopping the dust bag 320 from continuing to collect waste. This prevents problems such as waste leakage that makes waste difficult to clean and may cause malfunctions in the waste collection base station 1000.
