The cleaning robot 2100 may be a sweeping robot, a sweeping and mopping robot, a mopping robot, a handheld vacuum cleaner, a hand-pushed cleaning machine, or a driving cleaning machine.

[0059] Cleaning Robot

[0060] The cleaning robot 2100 includes a main body, on which a cleaning structure is provided, and the cleaning structure may be a sweeping part, a mopping part, a roller brush part, or a combination of any two or more of these parts. The cleaning structure is mainly used to automatically clean the cleaning area, and the 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.

[0061] Garbage collection base station

[0062] See also Figure 1 , Figure 6 , Figure 7 and Fig.17 The garbage recycling base station 1000 includes a base station body 100, a fan 200, a dust collecting component 300, a sensor 700, a dust full detection device 10 and a controller 800, etc.

[0063] See also Figure 8 and Fig.17 The garbage collection base station 1000 includes a base station body 100, on which a carrying part 101 for carrying a cleaning robot 2100 is provided. When the cleaning robot 2100 needs to discharge collected materials, needs to be charged, or needs to be placed after use, it can drive to the carrying part 101 for parking. A dust collection port is provided on the carrying part 101, and the dust collection port and the dust discharge port of the cleaning robot 2100 can be connected to each other. The cleaning robot 2100 discharges the collected materials into the garbage collection base station through the dust discharge port for collection.

[0064] The shape of the base station body is not specifically limited, and can be either regular or irregular. For the convenience of description, the base station body is taken as an example of a roughly L-shaped shape. Figure 1 , Figure 8 and Fig.17 The carrying part 101 of the garbage collection base station 1000 is located in a lower position, and the upper surface of the carrying part 101 is used 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 wheel of the cleaning robot 2100, and a rear wheel positioning groove 103 for placing the rear wheel of the cleaning robot 2100. In particular, in the direction in which the cleaning robot 2100 drives onto the carrying part 101, the groove width of the front wheel positioning groove 102 gradually decreases, which guides the movement of the front wheel. A charging electrode 104 is provided on the carrying part 101, and when the cleaning robot 2100 is parked on the carrying part 101, the cleaning robot 2100 can be charged through the charging electrode 104.

[0065] The base station body 100 is an installation carrier, which has a supporting structure fixed to the ground, a bearing 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.

[0066] See also Figure 3The 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 dust inlet channel 110 and the air extraction channel 140 can be in the shape of a round tube, a square tube or 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 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.

[0067] See also Figure 1 and Figure 3 The 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 inlet and an air outlet, such as a blower, a ventilator, a centrifugal fan, etc., which can generate suction at the air inlet to inhale gas and discharge the inhaled gas 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 other cavities set inside the base station body 100 and separated from the receiving cavity 120. The fan 200 only needs to meet the requirements that its air inlet is connected to the exhaust channel 140 of the base station body 100, and its air outlet can be connected to the outside.

[0068] See also Figure 1 and Figure 3 The dust collecting component 300 can extend from the cavity opening 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.

[0069] 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 clamps, the buckling of the clamps 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, thereby enhancing the sealing effect.

[0070] 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 type sensor 700 or a non-contact type sensor 700; therefore, there are many types of sensors 700, such as a pressure sensitive 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 and cover the cavity opening of the receiving chamber 120.

[0071] The controller 800 is electrically connected to the sensor 700. The controller 800 can be a device such as a computer or a PLC, which can receive the signal of the sensor 700 and control the working state of the fan 200 according to the signal of the sensor 700. For example, when the sensor 700 detects that the dust collecting component 300 leaves its preset position, the dust collecting component 300 is no longer docked with the dust inlet channel 110 and the exhaust channel 140. The controller 800 controls the fan 200 to stop working after receiving the detection result. When the dust collecting component 300 is detected to be located at the preset position, the dust collecting component 300 is docked with the dust inlet channel 110 and the exhaust channel 140. The controller 800 controls the fan 200 to start working after receiving the detection result to complete the garbage collection function. The controller 800 can receive the signal of the sensor 700 through wireless transmission, such as Bluetooth, Wi-Fi, etc., or transmit and receive signals through a wired connection. Of course, the controller 800 can also control other devices electrically connected to it, such as electrically controllable devices such as motors, and the controller 800 can also add components such as switches that are manually controlled.

[0072] 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 collecting component 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 collecting component 300 is received in the receiving chamber 120, it is sealed and connected with the dust inlet channel 110 and the air extraction channel 140. A sensor 700 is further provided to detect whether the dust collecting component 300 is installed in a preset position in the receiving chamber 120, so as to ensure that the dust collecting component 300 is properly installed in the receiving chamber 120 when it is received, so that the dust collecting component 300 is accurately connected with the dust inlet channel 110 and the air extraction channel 140, so as to prevent the leakage of garbage and dirt in the receiving chamber 120 when the garbage collection base station 1000 is in operation, thereby increasing the difficulty of cleaning. A controller 800 is provided to receive the signal of the sensor 700 and control the operation state of the fan 200, so as to further improve the intelligence of the garbage collection base station 1000.

[0073] In one embodiment, see Figure 1 and Figure 4a The dust collecting assembly 300 includes a bearing body 310 and a dust collecting bag 320. The bearing body 310 is telescopically mounted in the receiving cavity 120. The bearing body 310 is provided with a receiving cavity 311. The receiving cavity 311 has an installation opening 312 open to the outside. The opening direction of the installation opening 312 is perpendicular to the telescopic direction of the bearing body 310. The dust collecting bag 320 is received in the receiving cavity 311 through the installation opening 312. The bearing body 310 drives the dust collecting bag 320 to extend or be received in the receiving cavity 120 to facilitate its disassembly and cleaning. The bearing body 310 can be made of a certain rigid material, such as metal, plastic, etc., so that it is not easy to deform, which is conducive to carrying the dust collecting bag 320 and preventing it from falling off.

[0074] Among them, the supporting 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; alternatively, the supporting 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 bag 320 is taken out to dump the garbage.

[0075] In other implementations, the carrier body 310 is fixedly connected to the base station body 100 .

[0076] The supporting body 310 with the mounting opening 312 can have 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 be in other shapes, and it only needs to have a storage cavity 311 to support and fix the dust bag 320.

[0077] The dust bag 320 can be just a soft filter bag, or a dust bag 320 in which a supporting skeleton outer shell is provided with a soft filter bag. There are many choices of materials for the dust bag 320, such as water-repellent and oil-proof felt, polyester needle-punched felt, three-proof polyester needle-punched felt, etc. Preferably, the dust bag 320 is made of water-repellent and oil-proof felt, which has dense fabrics, good particle retention and dust filtering effect.

[0078] Further, 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 supporting 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 arranged between the top plate 313 and the bottom plate 314. When the supporting body 310 is retracted into the receiving cavity 120, the top plate 313 covers the cavity opening, and the sealing ring 313a is sealed and fitted between the top plate 313 and the peripheral side wall of the receiving cavity 120.

[0079] The sealing ring 313a can be a hard structure or a soft structure. When a hard structure is selected, it is generally buckled or fitted with the structure set at the periphery of the cavity opening of the receiving cavity 120 to achieve a sealing effect. For example, a circle of grooves is set around the cavity opening of the receiving cavity 120, and the sealing ring 313a is a convex ring that is convexly arranged to fit the groove. When the sealing ring 313a is a soft structure, it can be made of rubber, soft plastic, silicone and other materials, so that it can be squeezed between the top plate 313 and the cavity opening of the receiving cavity 120 and deformed, thereby blocking the surrounding gaps to ensure the sealing effect. The number of sealing rings 313a can be one or more, and is not specifically limited here.

[0080] To enhance the sealing and the stability of the combination between the carrier body 310 and the receiving cavity 120, further, 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 buckle 400 and an elastic reset switch 500, and several active 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 buckles 400 to switch several active buckles 400 between a locked position and an unlocked position, wherein the active buckle 400 is engaged with the card slot 121 in the locked position, and the active buckle 400 is separated from the card slot 121 in the unlocked position.

[0081] 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 that is 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 such elastic materials.

[0082] 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.

[0083] 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.

[0084] For further information, see Figure 1 and Figure 2 , at least one slot 121 includes two slots 121 arranged opposite to each other, at least one active buckle 400 includes two active buckles 400 arranged opposite to each other, at least one guide channel 360 includes two guide channels 360 arranged opposite to 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 arranged in parallel and a connecting arm 520 connecting the two elastic arms 510, and the positions of the two elastic arms 510 away from the connecting arm 520 are respectively connected to the ends of the active buckles 400 on the corresponding sides. Such a configuration can further enhance the stability of the cooperation between the bearing body 310 and the receiving cavity 120, and also facilitate the elastic reset switch 500 to apply force to the active buckle 400.

[0085] The elastic arm 510 is a structure that can be deformed when subjected to force. It drives the movable buckle 400 to move by deformation, and then controls whether the movable buckle 400 is engaged with the card 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 are prone to deformation when subjected to force, such as thin iron plates or aluminum plates. 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 made separately and connected together by bolt connection, riveting or welding.

[0086] To prevent the elastic arm 510 from being insufficiently elastic or losing its elasticity due to long-term use, so that the movable buckle 400 cannot be reset, please refer to Figure 5 The elastic reset switch 500 further includes a reset spring 530 located in the clearance groove 340 and elastically connected to the two movable buckles 400. The ends of the two movable buckles 400 extending into the clearance groove 340 are both provided with a clamping protrusion 410. The two clamping protrusions 410 are installed between the two elastic arms 510. The two clamping protrusions 410 fit with the corresponding elastic arms 510 under the action of the reset spring 530 on the movable buckle 400. The reset spring 530 is a compression spring, and the materials and processing technology used by the conventional springs are within the protection scope of the present invention.

[0087] In one embodiment, see Figure 4b The dust collecting assembly 300 includes a dust collecting body 301, which is telescopically mounted on the receiving chamber 120. The dust collecting body 301 is provided with an air inlet 301a corresponding to the dust inlet channel 110 and a filter screen 301b corresponding to the air extraction channel 140, and a dust collecting chamber 301c connecting the air inlet 301a and the filter screen 301b. The dust collecting chamber 301c is connected to the dust inlet channel 110 via the air inlet 301a, and the dust collecting chamber 301c is connected to the air extraction channel 140 via the filter screen 301b. The filter screen 301b can be a device with a filtering structure such as a cloth fabric or a metal fabric, which can be connected to the air extraction channel 140 so that the clean air filtered by it can be extracted. The dust collecting assembly 300 can be separated from the receiving chamber 120, so that it is convenient for the user to take out the dust collecting assembly 300 to dump garbage. The dust collecting body 301 is provided with an openable flip cover, so as to facilitate opening the flip cover and collecting the garbage inside the dust collecting body 301 .

[0088] The shape and size of the filter 301b can be set 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 collecting chamber 301c. The filter 301b is fixed to the carrier body 301, and the filter 301b and the carrier body 301 can be separated from the receiving chamber 120 together to dump garbage. The carrier body 301 or the filter 301b can be provided with a flap, so that the flap can be opened to dump garbage. In another embodiment, the filter 301b is a filter screen plate, and the carrier body 301 has an air inlet 301a and a dust collecting chamber 301c.

[0089] In one embodiment, see Figure 3 The receiving chamber 120 has a cavity opening 122 and a cavity bottom 123 that are arranged relatively, and the cross-sectional area of ​​the receiving chamber 120 is gradually reduced from the cavity opening 122 to the cavity bottom 123, and 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 the leakage of air with dirt, and the dust collecting component 300 and the inner wall of the receiving chamber 120 are matched with an inclined surface, which can reduce the mutual friction between the two during the process of the dust collecting component 300 extending or being received 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 the good sealing of the garbage collection base station 1000.

[0090] In one embodiment, see Figure 1 , Figure 2 and Figure 5 , two elastic plates 330 are convexly arranged in parallel on one side of the bottom of the receiving chamber 120 of the dust collecting component 300, and the surfaces of the two elastic plates 330 facing the cavity wall of the receiving chamber 120 are convexly provided with stop protrusions 331; two matching protrusions 130 are correspondingly arranged on the cavity wall of the receiving chamber 120 adjacent to the cavity opening 122, and the two matching protrusions 130 can match with the corresponding stop protrusions 331. Such an arrangement can limit the position of the dust collecting component 300. When the dust collecting component 300 moves away from the receiving chamber 120, the stop protrusion 331 and the matching protrusion 130 form a card position to prevent the dust collecting component 300 from continuing to move, so that the dust collecting component 300 can be kept in a state of extending relative to the receiving chamber 120, which is convenient for users to take out the dust bag of the dust collecting component 300, and prevents the operator from using excessive force to completely pull the dust collecting component 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.

[0091] The elastic plate 330 may be made of a variety of materials, such as metal, plastic or rubber. There may be one or more stop protrusions 331 on each elastic plate 330, and the number of the matching protrusions 130 on the inner wall of the receiving cavity 120 opposite to the elastic plate 330 corresponds to the number of the stop protrusions 331. The stop protrusions 331 and the matching protrusions may be round dot protrusions, bar protrusions, etc., which are not specifically limited here.

[0092] In one embodiment, see Figure 2 and Figure 5 , the two elastic plates 330 are both provided with a clearance hole 332, the garbage collection base station 1000 also includes a movable lock 600, the movable lock 600 includes two movable plates 610 and an elastic reset member 620, one end of the two movable plates 610 extends from the corresponding clearance holes 332, and the two ends of the elastic reset member 620 are respectively connected to the ends of the two movable plates 610 away from the corresponding clearance holes 332, so as to elastically support the two movable plates 610. This arrangement can provide the dust collection assembly 300 with a fixed position extending out of the receiving cavity 120, freeing the hands of the operator and facilitating the operator to clean dust and dirt.

[0093] When the dust collecting component 300 moves away from the receiving chamber 120, the two movable plates 610 are squeezed by the matching protrusions 130 and shrink toward each other. When the two movable plates 610 move to the top of the matching protrusions 130 and are no longer squeezed, the two movable plates 610 extend back due to the action of the elastic reset members 620. When the force applied to the dust collecting component 300 away from the receiving chamber 120 is removed, due to the action of gravity, the two movable plates 610 abut against the matching protrusions 130 to form a locking position, thereby fixing the position of the dust collecting component 300.

[0094] It should be noted that the clearance hole 332 may be a circular hole, a square hole or a hole of other shapes, and one end of the movable plate 610 adjacent to the clearance hole 332 is configured to match the shape of the clearance hole 332. The elastic reset member 620 may be a spring, or an elastic rubber member.

[0095] 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 the width of the second section 611, the first section 611 is clearance-matched 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 reset member 620. This arrangement can accurately control the travel of the movable plate 610, and prevent the movable plate 610 from hitting the inner wall of the receiving cavity 120 when it is reset due to the action of the elastic reset member 620, causing damage to the inner wall of the receiving cavity 120.

[0096] The second section 611 may be wider than the first section 611 as a whole, or may be wider than the first section 611 by protruding on one side, which is not specifically limited here. The second section 611 may be connected to the elastic reset element 13a by detachable clamping or fixed connection by welding.

[0097] In one embodiment, see Figure 5 The surface of the dust collecting assembly 300 away from the cavity opening 122 of the receiving cavity 120 is also provided with a convex pivoting platform 350 which is arranged opposite to each other. The two pivoting platforms 350 are located between the two elastic plates 330, and the two pivoting platforms 350 are respectively pivoted to the middle of the corresponding movable plate 610. Such a configuration can enhance the stability of the connection between the movable lock 600 and the dust collecting assembly 300. The pivoting of the pivoting platform 350 and the movable plate 610 can be a rigid pivoting connection through a plug-in shaft, or a flexible pivoting connection through a hinge or the like, which only needs to satisfy the function of connecting the movable lock 600 firmly without hindering its movement.

[0098] In one embodiment, see Figure 6 and Figure 7 In 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, which is installed on the base station body 100, and the lifting mechanism 900 is connected to the dust collecting component 300 to drive the dust collecting component 300 to rise and fall.

[0099] 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 collecting assembly 300, and the rack 920 extends along the cavity bottom 123 of the receiving cavity 120 toward the cavity opening 122 of the receiving cavity 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 in the receiving cavity 120, and is meshed with the rack 920. In other embodiments, the lifting mechanism 900 can also be a screw thread matching mechanism, or a connecting rod mechanism, etc.

[0100] 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.

[0101] Dust detection device

[0102] See also Figure 1 and Fig. 9The garbage collection base station 1000 further includes a dust full detection device 10, which is fixed to the base station body 100 and is used to detect whether the dust collection component 300 meets the preset dust full condition, and generates a dust full signal when the dust collection component 300 meets the preset dust full condition. The controller 800 of the garbage collection base station 1000 is electrically connected to the dust full detection device 10 and the fan 200, and the controller 800 is used to receive the dust full signal of the dust full detection device 10, and control the fan 200 to stop working according to the dust full signal of the dust full detection device 10.

[0103] In addition, in one embodiment, the controller 800 is electrically connected to the dust full detection device 10, and the controller 800 is also used to control the lifting mechanism 900 to drive the dust collection component 300 to rise according to the dust full signal of the dust full detection device 10 when receiving the dust full signal of the dust full detection device 10. Therefore, on the one hand, the controller 800 can detect that the dust collection component 300 leaves the preset position in the receiving chamber 120 according to the sensor 700, and control the fan 200 to stop working, thereby shortening the dust extraction time in time; on the other hand, the user can intuitively know from the raised dust collection component 300 that the dust collection component 300 is full of garbage and needs to be dumped.

[0104] Specifically, when the controller 800 receives the dust full signal, it sends a command 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.

[0105] 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 (eg, Fig.15 As shown in the figure, a storage chamber 311 is provided in the carrier body 310, and a dust collecting bag 320 is installed in the storage chamber 311 to collect garbage; or the dust collecting assembly 300 includes a dust collecting body, and a dust collecting chamber is directly provided in the dust collecting body, and the dust collecting chamber collects garbage. The following mainly explains that the dust collecting assembly 300 includes a carrier body 310 and a dust collecting bag 320.

[0106] The understanding of whether the preset dust full condition is met can be:

[0107] When the dust collecting component 300 continuously inhales the collected matter, the total weight of the collected matter continuously increases. When the weight exceeds a certain preset weight value, it can be considered that the dust collecting component 300 has met the preset dust full condition. Alternatively, when the dust collecting component 300 continuously inhales the collected matter, the gas flow resistance in the dust collecting component 300 increases, thereby greatly reducing the dust suction force in the dust inlet channel 110. At this time, it can be considered that the dust collecting component 300 has met the preset dust full condition.

[0108] The means for detecting whether the dust collecting assembly 300 meets the preset dust full condition are:

[0109] A weight determination method is adopted. 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. The controller is installed on the base station body 100, and the controller is electrically connected to the pressure detection device and the fan 200 at the same time. When the controller receives the dust full signal from the pressure detection device, the controller controls the fan 200 to stop working. Among them, the electrical connection between the components can be a wire connection or a wireless connection.

[0110] The determination method using air pressure changes. Fig.13a For 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 receiving chamber 311, and the free end 11b of the pipe 11 is arranged away from the receiving chamber 311. The sensing component 12 is fixed to the connecting end 11a or the free end 11b of the pipe 11.

[0111] The floating component 13 can be movably installed in the pipe 11, and can move between the connecting end 11a and the free end 11b in response to the change of air pressure in the storage chamber 311. When the dust bag 320 meets the preset dust full condition, the floating component 13 responds to the negative pressure in the storage chamber 311 and moves closer to the connecting end 11a relative to the sensing component 12, and triggers the sensing component 12 to generate a dust full signal.

[0112] The sensing component 12 may be used in a variety of ways, such as using a light sensor, a Hall sensor 12c or a pressure sensor 12d.

[0113] When the dust bag 320 meets the preset dust full condition, the floating assembly 13 moves from the first position to the second position.

[0114] The sensing component 12 includes a light emitter 12a and a light receiver 12b arranged relative to the light emitter 12a, and 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;

[0115] 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;

[0116] Alternatively, the sensing component 12 includes a pressure sensor 12d, and the floating component 13 contacts the pressure sensor 12d at the first position and is away from the pressure sensor 12d at the second position.

[0117] Specifically, when the sensing component 12 is a light sensor, please refer to Fig.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 shielding plate 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, such as Fig.12 The floating component 13 does not block the optical signal between the optical transmitter 12a and the optical receiver 12b in the second position.

[0118] When the sensing component 12 includes the Hall sensor 12c, the floating component 13 has a certain magnetism. Fig.13a and Fig.13b In operation, the floating component 13 has a first position, in which the floating component 13 is adjacent to the Hall sensor 12c. Fig.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 arranged away from the Hall sensor 12c at the second position, as shown in FIG. Fig.13b shown.

[0119] When the sensing component 12 includes a pressure sensor 12d, see Fig.14a and Fig.14b In operation, the floating assembly 13 has a first position, in which the floating assembly 13 contacts the pressure sensor 12d. Fig.14aWhen 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, and the floating component 13 is away from the pressure sensor 12d at the second position. Fig.14b shown.

[0120] The above several situations adopted by the sensing component 12 belong to the technical solutions of the same concept. In addition, under the concept or basis of the present invention, alternative solutions that can be easily thought of by those skilled in the art belong to the scope of protection of this application. In addition, in the above situation, after the floating component 13 is displaced, it can be reset manually, or a return mechanism can be set to automatically reset. The return mechanism can adopt an elastic return element 13a or a drive mechanism and other implementation schemes. The use of the elastic return element 13a is described in detail below.

[0121] The floating component 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 for the floating member 13b to move away from the connecting end 11a, so that the floating member 13b moves relative to the sensing component 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.

[0122] 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.

[0123] See also Fig.11 , a spring is disposed in the pipe 11, one end of the spring is fixed, and the other end is connected to the floating component 13b. During operation, the floating component 13 has a first position, and the floating component 13 blocks the optical signal between the optical transmitter 12a and the optical receiver 12b in the first position. When the dust bag 320 meets the preset dust full condition, a negative pressure is generated in the storage chamber 311, the floating component 13b moves toward the connecting end 11a of the pipe 11 and compresses the spring, and the floating component 13 moves to the second position, and the floating component 13 does not block the optical signal between the optical transmitter 12a and the optical receiver 12b in the second position. Afterwards, when the negative pressure in the storage chamber 311 is released, the floating component 13b moves to the initial position under the restoring force of the spring.

[0124] Based on this embodiment, there are some parallel solutions or alternative solutions. For example, the spring can be arranged outside the free end 11b of the pipe 11; or the spring is partially located inside the pipe 11 and partially located outside the free end 11b of the pipe 11. The fixed end of the spring is fixed to the connecting end 11a of the pipe 11 or to the free end 11b of the pipe 11, etc.

[0125] In summary, the dust full detection device 10 is mainly described. However, one thing needs to be mentioned, that is, the dust full detection device 10 is connected to the storage chamber 311 either directly or indirectly. Direct connection means that the connection end 11a of the pipe 11 is directly connected to the storage chamber 311, and indirect connection 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 connection, for example, the above-mentioned air extraction 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 air extraction channel 140. Or as exemplified below, there is a case where an expansion space 30 is provided.

[0126] Dust collection components

[0127] See also Fig.15 The dust collecting assembly 300 includes a bearing body 310 and a dust collecting bag 320. The bearing body 310 includes a top plate 313, a bottom plate 314 arranged opposite to 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 plate 315 are arranged to form a storage chamber 311. The storage chamber 311 has an open installation opening 312. The installation opening 312 is perpendicular to the installation direction or disassembly direction of the bearing 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.

[0128] For further information, see Figure 1 , Fig. 9 , Fig.10 and Fig.16 The garbage collection base station 1000 includes a dust full detection device 10 and a controller 800. The bearing 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 air 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 air 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.

[0129] The dust full detection device 10 is used to detect whether the dust collecting assembly 300 meets the preset dust full condition, and generates a dust full signal when the dust collecting assembly 300 meets the preset dust full condition. The controller 800 is used to receive the dust full signal of the dust full detection device 10, and control the fan 200 to stop working according to the dust full signal of the dust full detection device 10.

[0130] 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 and the storage chamber 311 remain in communication, and the dust full detection device 10 and the storage chamber 311 remain in communication.

[0131] See also Figure 1 , Fig. 9 , Fig.10 and Fig.16 , wherein the surface of the bottom plate 314 near the top plate 313 is provided with a rib structure 20, a first vent 50 and a second vent 60. 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, and 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 air extraction 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 air flow around the dust bag 320 to the first vent 50, so as to ensure that the dust bag 320 continues to collect garbage under the action of vacuum.

[0132] 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.

[0133] Furthermore, the bottom surface of the carrier body 310 is sunken to form an expansion space 30, the expansion space 30 is connected to the first vent 50, and the dust full detection device 10 is connected to the storage chamber 311 through the expansion space 30 and the first vent 50. Fig.10The bottom plate 314 is formed with an expansion space 30 on the surface of the side away from the top plate 313, and the expansion space 30 is connected to the first vent 50. The connecting end 11a of the pipe 11 is connected to the receiving chamber 311 through the expansion space 30 and the first vent 50. It can be understood that a separate expansion space 30 is provided to communicate with the pipe 11, and a buffer space is formed between the receiving chamber 311 and the pipe 11, so as to ensure that there is a large enough space outside the connecting end 11a of the pipe 11, so that there is enough force to move the floating member 13b when negative pressure is formed.

[0134] Furthermore, the rib structure 20 includes a barrier 40 , the barrier 40 covers the first vent 50 , and a gap is provided between the barrier 40 and the first vent 50 .

[0135] In this embodiment, in order to prevent the dust bag 320 from blocking the first vent 50 after expansion, thereby 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, such as Fig.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 is expanded, it is directly pressed on the barrier 40 for support, and there is a gap between the barrier 40 and the first vent 50, thereby ensuring that the first vent 50 is connected to the air flow channel 70. In other embodiments, the barrier 40 can also be set at other positions of the carrier body 310, which can be set as needed.

[0136] The garbage collection base station 1000 of the present invention includes a dust full detection device 10, which detects whether the dust collection component 300 meets the preset dust full condition, and generates a dust full signal when the dust collection component 300 meets the preset dust full condition, so that the user can clean the dust bag 320 in time after receiving the dust full signal. In addition, after receiving the dust full signal generated by the dust full detection device 10, the controller set in the base station body 100 controls the fan 200 to stop working, so as to stop the dust bag 320 from continuing to collect garbage, so as to avoid the problem that the garbage is difficult to clean due to garbage leakage and the possible malfunction of the garbage collection base station 1000.
