DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0027] The present application proposes a cleaner 100, a docking station 400 and a cleaning system. By utilizing the original suction assembly 120 of the cleaner 100 for dust collection, an AC motor may not be separately provided in the dust box 200 of the docking station 400, thereby reducing noise and cost.

[0028] In the related art, the docking station 400 can also be used to charge the cleaner 100. When the AC motor is added to the docking station 400, the power supply circuit in the docking station 400 is divided into two parts, one of which is used to power the cleaner 100, and the other of which is used to power the AC motor. Apparently, removing the AC motor can also simplify the layout of the power supply circuit in the docking station 400.

[0029] As shown in FIG. 1 and FIG. 2, an embodiment of the present application provides a cleaner 100.

[0030] In this embodiment, the cleaner 100 is used to connect to the dust box 200, and the dust box 200 is equipped with a dust passage 201. The cleaner 100 includes a cleaner body 110, a suction assembly 120, a dust cup 130 and a duct assembly 140. The cleaner body 110 is equipped with an inlet passage 101; the suction assembly 120 is installed on the cleaner body 110; the dust cup 130 is installed on the cleaner body 130, and an inner cavity of the dust cup 130 is in communication with the inlet passage 101. When the cleaner 100 cooperates with the dust box 200, the inner cavity of the dust cup 130 is in communication with an air inlet of the dust passage 201; the dust cup 130 is equipped with a separation assembly 132, and the separation assembly 132 is equipped with a separation passage 133 in communication with the inner cavity of the dust cup 130; the passage assembly 140 is installed on the cleaning main body 110, and the passage assembly 140 is equipped with a first passage 102 and a second passage 103, the first passage 102 is in communication with the air inlet of the suction assembly 120, and the second passage 103 is in communication with the separation passage 133. When the cleaning main body 100 cooperates with the dust box 200, the first passage 102 is in communication with the air outlet of the dust passage 201, and the second passage 103 is blocked.

[0031] In this embodiment, when the cleaner 100 cooperates with the dust box 200, the dust passage 201 in the dust box 200 is in communication with the inner cavity of the dust cup 130, and is in communication with the suction assembly 120 of the cleaner 100 through the first passage 102. When the cleaner 100 collects dust, the suction assembly 120 is started. Since the second passage 103 is blocked, the air sucked into the inlet passage 101 cannot flow through the separation passage 133 and the second passage 103 after entering the inner cavity of the dust cup 130, and can only flow to the dust passage 201, thereby blowing the garbage in the inner cavity of the dust cup 130 into the dust passage 201, thereby dust collection can be achieved without setting a motor in the dust box 200. Compared with the dust collection scheme of arranging an AC motor in the dust box 200, the noise is reduced, the structure of the dust box 200 is simplified, and the cost is reduced.

[0032] In some embodiments, the cleaner 100 can be a vacuum cleaner host, which is usually a handheld part. Of course, the cleaner 100 can also be a sweeping robot, which is not limited in this embodiment.

[0033] The suction assembly 120 can include a brushless motor and its accessories, etc. The suction assembly 120 is used to provide suction. When the cleaner 100 is used for cleaning, the cleaner 100 can be connected to a cleaning component 300 such as a floor brush, and the inlet passage 101 is in communication with the cleaning component 300, and the cleaning component 300 is placed on the plane to be cleaned. After the suction assembly 120 is started, the garbage on the plane to be cleaned enters the cleaning duct 310 in the cleaning component 300, and then enters the dust cup 130 through the inlet passage 101. The garbage and air are separated in the separation assembly 132 in the dust cup 130. After separation, the garbage is retained in the dust cup 130, and the air enters the second passage 103 and is discharged through the suction assembly 120.

[0034] As shown in FIG. 3, in some embodiments, the dust box 200 may include a box body 210 and a dust bag 220 which is breathable, the box body 210 is equipped with a collection chamber 211, a accommodating chamber 212 and a return air passage 202. The collection chamber 211 has a dust collection port, and an air inlet of the return air passage 202 is in communication with the accommodating chamber 212. When the box body 210 cooperates with the cleaner 100, the collection chamber 211 is in communication with the inner cavity of the dust cup 130 in the cleaner 100, and the air outlet of the return air passage 202 is in communication with the first passage 102 of the cleaner 100; the dust bag 220 is arranged in the accommodating chamber 212, and the bag opening of the dust bag 220 is in communication with the dust collection port.

[0035] In this embodiment, the collection chamber 211, the accommodating chamber 212, the dust bag 220 and the return air passage 202 form the dust passage 201. The garbage and air in the dust cup 130 enter the dust bag 220 through the collection chamber 211, and the air passes through the dust bag 200 and enters the accommodating chamber 212, and then enters the return air passage 202.

[0036] In some embodiments, the bottom cover 131 of the dust cup 130 is designed to be openable and closable, and is equipped with a locking block 135. The locking block 135 can be used to open the bottom cover 131. A protrusion 213 can be correspondingly provided in the collection chamber 211 of the dust box 200. When the cleaner 100 cooperates with the dust box 200, the protrusion 213 abuts against the locking block 132, and the bottom cover 131 is opened, so that the inner cavity of the dust cup 130 is in communication with the collection chamber 211.

[0037] In some embodiments, the position of the air inlet of the first passage 102 on the cleaner 100 corresponds to the position of the air outlet of the return air passage 202 on the box body 210, so that when the cleaner 100 cooperates with the dust box 200, the air inlet of the first passage 102 can be in communication with the air outlet of the return air passage 202, and the first passage 102 and the return air passage 202 are communicated.

[0038] When the cleaner 100 is separated from the dust box 200, the first passage 102 is closed and the second passage 103 is opened. The cleaner 100 can be used for cleaning when it is separated from the dust box 200, and the operation mode under cleaning can refer to the aforementioned.

[0039] In this embodiment, the passage assembly 140 is used to open or close the first passage 102 to achieve passage switching. When the first passage 102 is opened, the air flow can flow from the first passage 102 to the suction assembly 120; when the first passage 102 is closed, the first passage 102 does not allow the air flow to pass through.

[0040] In some embodiments, the passage assembly 140 can switch the passage under the operation of the user, or, the passage assembly 140 can switch passage by cooperating with the corresponding structure of the dust box 200 or not.

[0041] It can be understood that when the cleaner 100 cooperates with the dust box 200, the suction assembly 120 is started, and the air enters the dust cup 130 from the inlet passage 101 and then flows to the collection chamber 211. At this time, the garbage in the dust cup can be blown to the collection chamber 211 due to the flow of air, thereby improving the garbage collection efficiency. The garbage enters the dust bag 220 through the collection chamber 211 and is intercepted. The airflow passes through the dust bag 200 and enters the accommodating chamber 212, and then enters the return air passage 202; then the airflow is discharged through the first passage 102 and the suction assembly 120.

[0042] In some embodiments, when the cleaner 100 cooperates with the dust box 200, it may not be connected to the cleaning assembly 300. At this time, when the cleaner 100 collects dust, the airflow in the environment directly enters from the air inlet of the inlet passage 101.

[0043] In some embodiments, when the cleaner 100 cooperates with the dust box 200, it may be connected to the cleaning assembly 300. At this time, when the cleaner 100 collects dust, the airflow in the environment passes through the cleaning passage 310 in the cleaning assembly 300 and then enters the inlet passage 101.

[0044] In some embodiments, the separation assembly 132 may include a cyclone cone and a filter net. When the cleaner 100 is used for cleaning, the garbage enters the dust cup 130 together with the airflow. The separation assembly 132 separates the garbage from the airflow, and the garbage is retained in the inner cavity of the dust cup 130. The airflow passes through the cyclone cone and the filter net to enter the suction assembly 120, and the gas flow of the cyclone cone and the filter net forms a separation passage 133, and an outlet of the cyclone cone is the outlet of the separation passage 133. The structure and principle of the cyclone cone belongs to mature technology, and this embodiment will not be repeated here.

[0045] In this embodiment, when the cleaner 100 collects dust, the second passage 103 is in a blocked state, that is, the airflow in the dust cup 130 cannot pass through the second passage 103. Therefore, when the cleaner 100 cooperates with the dust box 200 and collects dust, the suction assembly 120 is started, and the air sucked into the inlet passage 101 enters the dust box 200 through the bottom of the dust cup 130. Since all the air volume is used for dust collection, the dust collection efficiency is improved.

[0046] As shown in Fig. 1 to Fig. 5, in some embodiments, the passage assembly 140 includes a passage body 150 and a sealing assembly 160. The passage body 150 is installed on the cleaner 100. The passage body 150 is equipped with a communicating cavity 151. The communicating cavity 151 is equipped with a first opening 152, a second opening 153 and a third opening 154. The first opening 152 is in communication with the air inlet of the suction assembly 120, the second opening 153 is in communication with the separation passage 132, and the third opening 154 is used to be in communication with the dust passage 201; the sealing assembly 160 is flexibly installed on the passage body 150. When the cleaner 100 cooperates with the dust box 200, the sealing assembly 160 opens the third opening 154, and the second opening 153 is closed by the sealing assembly 160 or by the tube body of the dust passage 201.

[0047] In this embodiment, the first opening 152, the communicating cavity 151 and the third opening 154 form the first passage 102, and the first opening 152, the communicating cavity 151 and the second opening 153 form the second passage 103. When the sealing component 160 closes the third opening 154, the second opening 153 is opened at the same time, the first passage 102 is blocked, and the second passage 103 is opened; when the first sealing component 160 opens the third opening 154, the second opening 153 is closed at the same time, the first passage 102 is opened, and the second passage 103 is blocked.

[0048] As shown in FIGS. 4 and 5, in some embodiments, the sealing assembly 160 includes an elastic member 161, a sealing plate 162 and a driving member 163, and the elastic member 161 is installed in the communicating cavity 151; the sealing plate 162 is connected to the elastic member 161, the sealing plate 162 has a first sealing part and a second sealing part, the driving member 163 is connected to the sealing plate 162, and when the cleaner 100 cooperates with the dust box 200, the driving member 163 cooperates with the driving portion 215 provided on the dust box 200 to drive the first sealing part to seal the second opening 153 and drive the second sealing part to unseal the third opening 154.

[0049] As shown in FIGS. 4 and 5, the sealing plate 162 is under the action of the elastic member 161 and is not driven by other components (that is, the driving member 163 is not subjected to external force). The second opening 153 is opened and the third opening 154 is closed. The elastic member 161 may be a spring.

[0050] In some embodiments, the second opening 153 and the third opening 154 may also be equipped with a sealing ring. When the first sealing part closes the second opening 153, or when the second sealing part closes the third opening 154, the sealing ring can improve the sealing effect.

[0051] In this embodiment, the dust box 200 is equipped with a driving part 215, and the driving part 215 is used to push the driving member 163. When the cleaner 100 cooperates with the dust box 200, the driving part 215 contacts the driving member 163, so that the driving member 163 drives the sealing plate 162 to move, thereby realizing the passage switching.

[0052] In some embodiments, the driving part 215 can also be operated by the user, for example, the driving part 215 can be operated to contact the driving member 163, so as to manually realize the passage switching.

[0053] In some embodiments, the sealing plate 162 can also use a sealing part to seal the second opening 153 or the third opening 154. That is, the sealing plate 162 moves to cover the second opening 153 to close it, and the third opening 154 is opened; or the sealing plate 162 moves to cover the third opening 154 to close it, and the second opening 153 is opened.

[0054] In some embodiments, the driving part 215 is arranged in the dust passage 201, and the passage body 150 is equipped with an extension passage 155 extending from the third opening 154 to a joint with the dust box 200; the driving member 163 includes a top rod, which is connected to the sealing plate 162 and is placed in the extension passage 155. When the cleaner 100 cooperates with the dust box 200, the extension passage 155 is in communication with the air outlet of the dust passage 201, and the top rod abuts against the driving part 215, and the first sealing part closes the second opening 153, and the second sealing part opens the third opening 154.

[0055] In some embodiments, when the cleaner 100 cooperates with the dust box 200, the cleaner 100 is located above the dust box 200. At this time, a joint with the dust box 200 is a downward direction. The extension passage 155 extends downward from the third opening 154, and the top rod is vertically arranged in the extension passage 155.

[0056] In some embodiments, the elastic member 161 is vertically arranged between the first sealing part and the second sealing part of the sealing plate 162, the first sealing part is located above the second opening 153, and the second sealing part is located above the third opening 154. In the first state, the second sealing part covers the third opening 154. The top rod can be connected to the second sealing part of the sealing plate 162. When the cleaner 100 cooperates with the dust box 200, the top rod abuts against the driving portion 215 and moves upward, thereby the second sealing part is lifted and the third opening 154 is opened. At this time, the first sealing part covers the second opening 153 downward, and the second opening 153 is closed.

[0057] It should be noted that when the cleaner 100 is cleaning, if the inlet passage 101 or the separation passage 133 is blocked, the connecting chamber 151 gradually forms a negative pressure. As the negative pressure increases, the second sealing part may be sucked up, the third opening 154 is open, and the connecting chamber 151 restores the atmospheric pressure, thereby protecting the suction assembly 120.

[0058] As shown in FIGS. 6 and 7, in other embodiments, the dust passage 201 on the dust box 200 has a tube body which is extended outward. When the cleaner 100 cooperates with the dust box 200, the sealing component 160 opens the third opening 154, the tube body of the dust passage 201 is inserted into the communicating cavity 151, and the air outlet of the dust passage 201 is in communication with the first opening 152, and the first passage 102 is in communication with the dust passage. At the same time, the tube body of the dust passage 201 can also play a role in isolating the second opening 153, so that the second passage 103 is blocked.

[0059] In some embodiments, the sealing assembly 160 includes a torsion spring 164 and a cover 165, and the torsion spring 164 is mounted on the passage body 150; the cover 165 is connected to the torsion spring 164 and is located outside the third opening 154, and the cover 165 has a contact portion, which is used to abut against the dust box 200 to flip the cover 165.

[0060] In this embodiment, the cover 165 covers the third opening 154 under the action of the torsion spring 164 to close it. The dust box 200 may be equipped with a driving portion 215 corresponding to the position of the contact portion. When the cover 165 abuts against the dust box 200, the driving portion 215 pushes the contact portion to flip the cover 165 outward around the torsion spring 164, thereby opening the third opening 154.

[0061] In some embodiments, the passage assembly 140 is further equipped with a third passage 104 and a switch assembly, the third passage 104 is in communication with the air outlet of the suction assembly 120 and the separation passage 133, and the switch assembly is used to control the third passage 104 to switch between an open state and a closed state.

[0062] It can be understood that after the cleaner 100 cooperates with the dust box 200 and the suction assembly 120 is started, the airflow flows from the air outlet of the suction assembly 120 into the third passage 104, and then flows through the inner cavity of the dust cup 130, the dust passage 201, the first passage 102 in a listed sequence, and finally returns to the suction assembly 120. Thus, the airflow can realize internal circulation between the cleaner 100 and the dust box 200, and play a cleaning effect on the internal components.

[0063] In some embodiments, a filter sponge 134 is provided in the dust cup 130, and the filter sponge 134 is usually arranged at the air outlet of the separation assembly 132 to filter dust. When the cleaner 100 performs internal circulation, the airflow passes through the filter sponge 134 and the separation assembly in a listed sequence, thereby blowing the dust on the filter sponge 134 to the inner cavity of the dust cup 130, and then entering the dust box 200 to clean the filter sponge 134.

[0064] It should be noted that when the cleaner 100 performs internal circulation, the inlet passage 101 needs to be blocked to avoid airflow turbulence in the dust cup 130. The inlet passage 101 can be blocked by covering or filling.

[0065] In some embodiments, the switch component includes a first valve 171 and a second valve 172, the first valve 171 is arranged at the connection between the third passage 104 and the air outlet of the suction assembly 120; the second valve 172 is arranged at the connection between the third passage 104 and the separation passage 133.

[0066] In this embodiment, the first valve 171 and the second valve 172 are used to control the connection and blocking of the third passage 104. When the first valve 171 and the second valve 172 are both open, the third passage 104 is communicated, and when the first valve 171 or the second valve 172 is closed, the third passage 104 is blocked.

[0067] In some embodiments, the first valve 171 can be switched on and off using the air pressure at the air outlet of the suction assembly 120. The second valve 172 can be controlled by the first sealing component 160. When the cleaner 100 cooperates with the dust box 200, the first sealing component 160 simultaneously opens the first passage 102 and the third passage 104, and simultaneously closes the second passage 103.

[0068] In some embodiments, the cleaner 100 may also include a third valve 173, which is disposed in the inlet passage 101 and is used to communicate the inlet passage 101 with the outside.

[0069] In this embodiment, the third valve 173 controls the switch through the air pressure difference. When the suction assembly is started, the air pressure in the inlet passage 101 decreases. When the pressure difference with the external air pressure reaches the threshold, the third valve 173 opens; then the air pressure in the inlet passage 101 gradually increases, and the third valve 173 closes, and repeats in sequence.

[0070] When the cleaner 100 collects dust, the airflow of the inlet passage 101 enters from the third valve 173. Since the air release of the third valve 173 is intermittent, the airflow in the cleaner 100 has a sufficiently large impact force at the moment when the third valve 173 is opened, thereby blowing the garbage in the dust cup 130 to the dust box 200, thereby improving the dust collection efficiency.

[0071] As shown in FIG. 8, in some embodiments, the inlet passage 101 and the first passage 102 are located on the same side of the dust cup 130.

[0072] In this embodiment, the first passage 102 can be arranged between the inlet passage 101 and the dust cup 130, and the main bodies of the first passage 102 and the inlet passage 101 are arranged vertically. Since the inlet passage 101 needs to tum when entering the dust cup 130, that is, the connection between the inlet passage 101 and the dust cup includes a horizontally arranged transition section, the position of the first passage 102 in the horizontal direction can overlap with the transition section. In FIGS. 6 and 7, the first passage 102 and the inlet passage 101 are arranged on both sides of the dust cup 130, and it is apparent that the first passage 102 needs to occupy an additional space. However, the arrangement of the first passage 102 in Figure 8 does not occupy additional space, thereby reducing the volume of the cleaner 100.

[0073] Referring to FIG. 9, an embodiment of the present application also provides a docking station 400, which includes a station body 410 and a dust box 200. The dust box 200 is used to connect the cleaner 100 according to the above. The dust box 200 may include the box body 210 and the dust bag 220. The box body 210 is equipped with the collecting chamber 211, the containing chamber 212 and the return air passage 202. The collecting chamber 211 has a dust inlet. The air inlet of the return air passage 202 is in communication with the containing chamber 212. When the box body 210 cooperates with the cleaner 100, the collecting chamber 211 is in communication with the inner cavity of the dust cup 130 in the cleaner 100, and the air outlet of the return air passage 202 is in communication with the first passage 102 of the cleaner 100; the dust bag 220 is arranged in the containing chamber 212, and the bag opening of the dust bag 220 is in communication with the dust inlet.

[0074] In this embodiment, the collecting chamber 211, the containing chamber 212, the dust bag 220 and the return air passage 202 form the dust collecting duct 201. The garbage and air in the dust cup 130 enter the dust bag 220 through the collection chamber 211, and the air passes through the dust bag 200 and enters the accommodating chamber 212, and then enters the return air passage 202.

[0075] In some embodiments, the box body 210 is equipped with a side cover 214 which is openable, and the side cover 214 is used to open or close the accommodating chamber 212.

[0076] It can be understood that the side cover 214 can facilitate the user to replace the dust bag 220 and prevent the garbage in the dust bag 220 from overflowing. A handle can be provided on the outside of the side cover 214 to facilitate the user to operate the side cover 214.

[0077] In some embodiments, when the box body 210 cooperates with the cleaner 100, the bottom cover 131 of the dust cup 130 is in an open state, and the dust box 200 also includes an operating member 230, which has an operating part 231 located outside the box body 210 and an action part 232 located in the collection chamber 211. The operating part 231 is used to drive the action part 232 to push the bottom cover 131 of the dust cup 130 to close.

[0078] In some embodiments, the bottom cover 131 of the dust cup 130 is designed to be openable and closable, and is equipped with a locking block 135. The locking block 135 can be used to open the bottom cover 131. A protrusion 213 can be correspondingly provided in the collection chamber 211 of the dust box 200. When the cleaner 100 cooperates with the dust box 200, the protrusion 213 abuts against the locking block 132, and the bottom cover 131 is opened, so that the inner cavity of the dust cup 130 is in communication with the collection chamber 211.

[0079] The position of the bottom cover 131 in the open state is located on the motion track of the action part 232. When the operation part 231 is operated, the action part 232 starts to move, thereby pushing the bottom cover 131 to move toward the bottom direction of the dust cup 130 until the bottom cover 131 covers the dust cup 130.

[0080] In some embodiments, the station body 410 is equipped with an accommodating part 411 and an air release passage 412 in communication with the outside, the air inlet of the air release passage 412 is in communication with the outside, and the air outlet of the air release passage 412 is exposed to the accommodating part 411. The accommodating part 411 is used to place the cleaning component 300, and when the cleaning component 300 is placed, the air release passage 411 is in communication with the cleaning passage 310 in the cleaning component 300; the station body 400 is equipped with the dust box 200 according to the above, and the cleaning component 300 is used to connect the cleaner 100 according to the above.

[0081] In this embodiment, the cleaner 100 can collect dust while being connected to the cleaning component 300. When the cleaner 100 collects dust, the airflow enters from the exhaust channel 412, then enters the cleaning passage 310 in the cleaning component 300, and then enters from the inlet passage 101 of the cleaner 100. In this way, dust collection can be achieved more conveniently. The user can collect dust at any time during the cleaning process of using the cleaner 100 without the need to additionally disassemble or assemble the cleaner 100, thereby improving the user experience.

[0082] According to the docking station 400 of the present application, when the cleaner 100 cooperates with the dust box 200, the dust passage 201 in the dust box 200 is in communication with the suction assembly 120 of the cleaner 100, so that the suction assembly 120 can be used to collect dust, and there is no need to arrange a motor in the dust box 200 or the docking station 400. Compared with the existing dust collecting solution, the structure of the whole machine is simplified and the cost of the whole machine is reduced. Of course, the docking station 400 can also adopt the technical solutions in the above-mentioned embodiments, and also have corresponding technical effects.

[0083] In some embodiments, the docking station 400 also includes a fourth valve 413, which is arranged at the air inlet of the air release passage 412. In this embodiment, the fourth valve 413 is switched by air pressure difference control. When the suction assembly is started, the air pressure in the air release passage 412 decreases. When the pressure difference with the external air pressure reaches a threshold, the fourth valve 413 opens; then the air pressure in the air release passage 412 gradually increases, and the fourth valve 413 closes, and the process is repeated.

[0084] When the cleaner 100 is collecting dust, the airflow enters from the fourth valve 413. Since the air release of the fourth valve 413 is intermittent, the airflow in the cleaner 100 has a sufficiently large impact force at the moment when the fourth valve 413 is opened, thereby blowing the garbage in the dust cup 130 to the dust box 200, thereby improving the dust collection efficiency.

[0085] In other embodiments, the docking station 400 is equipped with a docking portion for docking with the cleaner 100 that is not connected to the cleaning component 300, and the docking portion has an air intake cavity, and the air intake cavity is equipped with a fifth valve (not shown in the figure). When the cleaner 100 is docked with the docking portion, the air intake duct 101 is in communication with the air intake cavity. When the cleaner 100 is collecting dust, the fifth valve intermittently releases air to increase the impact force of the airflow, thereby improving the dust collection efficiency.

[0086] Continuing to refer to FIG. 9, an embodiment of the present application further provides a cleaning system, including a cleaner 100 according to the aforementioned and a docking station 400 according to the aforementioned. Among them, the structures and principles of the cleaner 100 and the docking station 400 can refer to the aforementioned, and this embodiment will not be repeated here.

[0087] According to the cleaning system of the present application, the dust box 200 on the docking station 400 does not need to be equipped with a motor. When the cleaner 100 cooperates with the dust box 200 and performs dust collection, the suction assembly 120 is started, and the air in the inner cavity of the dust cup 130 flows toward the dust box 200, thereby blowing the garbage in the inner cavity of the dust cup 130 into the dust box 200. Compared with the dust collecting solution of setting an AC motor in the dust box 200, the noise is reduced, the structure of the dust box 200 is simplified, and the cost is reduced. Of course, the cleaning system can also adopt the technical solutions in the above-mentioned embodiments, and also have corresponding technical effects.
