Referring to fig. 1, the present embodiment provides a cleaning apparatus, including: a body 110, a main body assembly 300 provided on the body 110, a floor brush unit 120 provided on a distal end of the body 110, and a handle 130 provided on a proximal end of the body 110.

The terms "proximal" and "distal" are relative to the user. The term "proximal" refers to a portion that is relatively close to the user, and the term "distal" refers to a portion that is relatively far from the user.

In one exemplary scenario, the cleaning apparatus is an upright cleaner for cleaning a floor surface. The floor brush unit 120 is provided with a dust suction port (not shown), which sucks up dirt (dust, debris, hair, etc.) on the floor to be cleaned under the action of the main unit 300. Hereinafter, the cleaning apparatus will be mainly explained as an upright type cleaner.

In the present embodiment, the body 110 has an elongated rod shape. The main body 110 is provided with at least one outlet communicating with the dust suction port. The main body 110 is hollow to form a dust collecting channel (not shown). The dust suction passage is used to communicate the outlet of the main body 110 with the dust suction port of the floor brush unit 120. The outlet is provided on a side wall of the dust suction passage, or the outlet is provided on a side wall of the main body 110.

Referring to fig. 2 and 3, the main unit assembly 300 at least includes a dust-air separating unit 320, a dust inlet structure for allowing the dust air to flow into the dust-air separating unit 320, and a main motor (not shown) for generating a negative pressure to allow the dust air to flow into the dust-air separating unit 320 through the dust inlet structure. Wherein, the dust inlet structure at least comprises a dust inlet.

Further, the main unit assembly 300 further includes an air inlet pipe 310 for delivering the dust and gas to the dust and gas separating unit 320, and the air inlet pipe 310 is provided with a dust and gas separating passage (not shown) communicated with the dust and gas separating unit 320. The main motor is used to generate a negative pressure in the dust-gas separation channel, so that the dust gas enters the dust-gas separation unit 320 through the dust-gas separation channel. Wherein, the dust-gas inlet is disposed on the dust-gas separation channel (inlet pipe 310) of the main unit 300.

In the present embodiment, the main unit assembly 300 is detachably provided to the body main body 110. The main unit assembly 300 has a first state mounted on the body 110 and a second state separated from the body 110. The first state in which the main unit assembly 300 is mounted on the main body 110 is a state in which the main unit assembly 300 is integrally formed with the main body 110. The second state in which the main unit 300 is separated from the main unit body 110 is a state in which the main unit 300 is detached from the main unit body 110.

When the mainframe assembly 300 is in the first state, the intake duct 310 is mounted on the outer wall of the body main body 110, thereby allowing the mainframe assembly 300 to be mounted on the body main body 110. At this time, the dust and air separating passage of the main unit 300 and the dust suction passage of the main body 110 are arranged side by side. The dust inlet of the main unit assembly 300 communicates with the outlet of the main body 110 to allow dust to enter the dust-air separating unit 320 through the dust suction port of the floor brush unit 120.

When the main unit assembly 300 is in the second state, the main unit assembly 300 is separated from the main body 110, and the dust air inlet is separated from the outlet of the main body 110, and at this time, the dust air directly flows into the dust air separating unit 320 through the dust air inlet structure. Wherein, when the main unit 300 is separated from the main body 110, the main unit 300 can be used as a hand-held cleaner.

In the present embodiment, referring to fig. 2, the dust inlet structure of the main assembly 300 includes two dust inlets, namely a first dust inlet 311 and a second dust inlet 312, which are disposed on the dust-air separation channel. That is, the air inlet pipe 310 is provided with the first dust and air inlet 311 and the second dust and air inlet 312. The first dust inlet 311 and the second dust inlet 312 can be used for switching the air path according to the state that the main unit assembly 300 is mounted on the main body 110 or separated from the main body 110, and the air conditioner has the advantage of convenience in use.

Wherein, when the main unit assembly 300 is in the first state, one of the first dust and air inlet 311 and the second dust and air inlet 312 is in an open state to communicate with the outlet on the main body 110, and the other dust and air inlet side is in a closed state. When the main unit assembly 300 is in the second state, at least one of the first dust inlet 311 and the second dust inlet 312 is in an open state for the external dust to enter the dust-gas separating unit 320.

In the present embodiment, the first dust and gas inlets 311 are distributed on the end of the distal end of the dust and gas separation channel; the second dust and gas inlets 312 are distributed on the side walls of the dust and gas separation channel. That is, the first dust and air inlet 311 is located at the free end of the air inlet pipe 310, and the second dust and air inlet 312 is located on the sidewall of the air inlet pipe 310.

Preferably, the main motor and the dust and air separating unit 320 are coaxially installed, the first dust and air inlet 311 is opened in a direction parallel to the axis, and the second dust and air inlet 312 is opened in a direction perpendicular to the axis. When the main unit assembly 300 is in the first state, the second dust inlet 312 is in sealed communication with the outlet of the main body 110, and the first dust inlet 311 is in the closed state.

In the present embodiment, please refer to fig. 4 and 5, the body main body 110 is provided with a first blocking piece 212 extending towards the proximal direction thereof. When the main unit assembly 300 is in the first state, the first blocking member 212 is sealingly inserted into the first dust and air inlet 311, so that the first dust and air inlet 311 is in a closed state. When the main unit assembly 300 is in the second state, the first blocking member 212 exits the first dust and air inlet 311, so that the first dust and air inlet 311 is in the open state.

Specifically, the shape of the first blocking piece 212 is the same or substantially the same as the shape of the first dust and air inlet 311. Preferably, the first dust and air inlet 311 is a circular hole, and the first blocking member 212 is a cylinder shape matching with the first dust and air inlet 311. Of course, the first dust and air inlet 311 and the first blocking member 212 may have other shapes, which are not described in detail herein.

In the present embodiment, please refer to fig. 2 and fig. 3, a second blocking piece 313 is disposed at the second dust and air inlet 312, and the second blocking piece 313 is slidably disposed on the outer wall of the main unit assembly 300 where the second dust and air inlet 312 is located along the length direction of the main body 110.

Preferably, the second blocking member 313 has a plate shape to be fitted to the outer wall of the main unit assembly 300. For example, when the outer wall of the main unit assembly 300 is a cylindrical surface, the second blocking member 313 is a circular arc plate; when the outer wall of the main unit assembly 300 is a flat plate, the second blocking member 313 has a flat plate shape. The above-mentioned length direction means: the distal-to-proximal direction of the body 110, or the proximal-to-distal direction of the body 110.

The position relationship between the second blocking piece 313 and the second dust and air inlet 312 includes the following two types: in the first position relationship, the second blocking element 313 blocks the second dust and air inlet 312, and it can be understood that the second blocking element 313 and the second dust and air inlet 312 are completely overlapped, and at this time, the second dust and air inlet 312 is in a closed state; in a second position, the second blocking member 313 is located at one side of the second dust and air inlet 312, and the second dust and air inlet 312 is completely opened, at this time, the second dust and air inlet 312 is in an open state. Wherein, when the main unit assembly 300 is mounted on the body main body 110,

further, a first switching mechanism 316 is disposed on the host component 300, and the first switching mechanism 316 is used for realizing the sliding action of the second blocking piece 313 on the outer wall of the host component 300. The first switching mechanism 316 is disposed on the air inlet pipe 310 of the mainframe assembly 300, and the first switching mechanism 316 includes a first elastic member 3161 and a valve housing 3162 disposed on an outer wall of the mainframe assembly 300 (on the outer wall of the air inlet pipe 310). The valve housing 3162 is internally hollow to form a mounting cavity extending in the sliding direction of the second blocking member 313. The valve housing 3162 is provided with an opening (not shown) through which the second blocking member 313 is inserted, and the opening of the valve housing 3162 is provided near the second dust and air inlet 312. The first elastic member 3161 is disposed in the mounting cavity, and two ends of the first elastic member 3161 abut against the mounting cavity and the second blocking member 313, respectively. The second blocking member 313 tends to keep closing the second dust and air inlet 312 by the biasing force of the first elastic member 3161.

In the present embodiment, referring to fig. 5, a first toggle member 213 is disposed on an outer wall of the main body 110, and the first toggle member 213 is configured to push the second blocking member 313 in a direction toward the proximal end of the main body 110 when the main unit 300 is mounted on the main body 110 (in the first state).

The first toggle member 213 and the first elastic member 3161 are distributed on two sides of the second blocking member 313, and the first toggle member 213 applies a toggle force opposite to the biasing force to the second blocking member 313 to force the second blocking member 313 to slide and retract into the mounting cavity, so as to open the second dust and air inlet 312.

In the present embodiment, when the main unit assembly 300 is removed from the main unit body 110 (in the second state), the second blocking member 313 extends out of the installation cavity under the action of the first elastic member 3161 and blocks the second dust and air inlet 312, so as to close the second dust and air inlet 312. At this time, the first blocking piece 212 exits the first dust and gas inlet 311, and the first dust and gas inlet 311 is in an open state. Thus, the main unit assembly 300 may suck the dust gas through the first dust gas inlet 311.

It is to be understood that when the main unit assembly 300 is in the second state, the first dust gas inlet 311 and the second dust gas inlet 312 may be in the open state. In the above case, the first dust gas inlet 311 is used to suck the dust gas; the second dust and air inlet 312 is connected to the outside atmosphere, and can reduce the suction force at the first dust and air inlet 311.

In the present embodiment, please refer to fig. 1, the cleaning apparatus further includes a traveling frame 200 disposed on the main body 110, and the main unit assembly 300 is disposed on the main body 110 through the traveling frame 200. Specifically, the air inlet pipe 310 of the main unit assembly 300 cooperates with the traveling carriage 200 such that the main unit assembly 300 is held on the traveling carriage 200 in the first state. As can be seen from the above, the main unit assembly 300 is detachably coupled to the body main body 110 by being detachably mounted to the traveling frame 200.

As shown in fig. 4, the traveling frame 200 is provided with a dust and air port structure communicated with the dust suction port, and the dust and air port structure at least includes a dust and air port 230. When the main unit assembly 300 is in the first state, the outlet of the main body 110 is in sealed communication with the second dust inlet 312 through the dust outlet 230.

As shown in fig. 4, the traveling carriage 200 includes a loading portion 210 for cooperating with an air inlet pipe 310 of the main unit assembly 300 to hold the main unit assembly 300 on the traveling carriage 200, and a connecting portion 220 disposed on the loading portion 210 for connecting with the main body 110.

In this embodiment, the sidewall of the air inlet pipe 310 of the main body assembly 300 is slidably disposed on the loading portion 210 along the lengthwise direction of the body main body 110. The longitudinal direction refers to a proximal to distal direction, or a distal to proximal direction.

Specifically, the cross section of the side wall 215 is one of arc, circular arc and broken line, so as to form an accommodating space for accommodating the air inlet pipe 310 with the bottom end plate 211. The bottom end plate 211 is disposed along an extending direction perpendicular to the loading portion 210, and is used for limiting the position of the main body assembly 300 in the longitudinal direction of the main body 110. In the first state, the distal end of the host module 300 abuts against the bottom plate 211, and the bottom plate 211 at least partially bears the weight of the host module 300.

Further, the first toggle member 213 and the dust port 230 are disposed on the side wall 215 of the loading portion 210. The first stirring member 213 is located above the dust outlet 230, and the first stirring members 213 are distributed along a direction (vertical direction) perpendicular to the installation direction of the host assembly 300. The first toggle member 213 is an elongated protrusion. In the present embodiment, during the installation of the main unit 300 on the traveling carriage 200, the second blocking member 313 is pushed open by the traveling carriage 200, so that the dust air flows into the dust-air separating unit 320 through the dust suction opening, the dust-air opening structure (the dust air opening 230) and the dust-air inlet structure.

Further, the first plugging member 212 is disposed on the bottom end plate 211. When the main unit 300 is held on the traveling frame 200, the first blocking member 212 is inserted into the first dust inlet 311 in a sealing manner, and the bottom end plate 211 blocks the first dust inlet 311, so that the first dust inlet 311 is closed, and the distal end of the main unit 300 abuts against the bottom end plate 211.

In the present embodiment, in order to enable the main unit assembly 300 to be conveniently mounted on the traveling frame 200 and be better retained on the traveling frame 200, please refer to fig. 5 in combination with fig. 6, one of the loading portion 210 and the air inlet pipe 310 is provided with a slot 214 extending along the longitudinal direction of the main body 110, and the other is provided with a locking rib 315 matching with the slot 214. The locking groove 214 and the locking rib 315 are used for limiting the installation between the main frame assembly 300 and the traveling rack 200.

Specifically, as shown in fig. 5 and fig. 6, the two side edges of the side surrounding plate 215 of the loading portion 210 along the longitudinal direction of the main body 110 are provided with bending portions 2141, and the bending portions 2141 form the locking grooves 214 at the two side edges of the side surrounding plate 215. Wherein, the outer wall of the air inlet pipe 310 is provided with a clamping rib 315 matched with the clamping groove 214.

Preferably, the side wall 215 has an arc-shaped cross section, which is a cross section perpendicular to the longitudinal direction of the fuselage main body 110. The cross-sectional shape of the slot 214 in the cross-section is generally "V" shaped. The cross-sectional shape of the latching rib 315 on the cross-section corresponds to the cross-sectional shape of the latching groove 214.

In the process of installing the mainframe assembly 300, first, the locking ribs 315 on the outer wall of the air inlet pipe 310 are aligned with the locking grooves 214 on the side enclosing plates 215 to achieve installation and positioning, and then, the air inlet pipe 310 of the mainframe assembly 300 is inserted into the accommodating space of the loading portion 210 from top to bottom. In the above process, the host module 300 can be smoothly installed on the traveling crane rack 200 through the clamping and matching between the clamping groove 214 and the clamping rib 315, after the host module 300 is installed in place, the first blocking piece 212 is hermetically inserted into the first dust and air inlet 311, and the end part (free end part) of the far end of the air inlet pipe 310 abuts against the bottom end plate 211.

In the present embodiment, the host unit 300 further includes a battery pack (not shown) for supplying power to the host motor. After the main unit assembly 300 is mounted on the traveling frame 200, the battery pack, the main motor, and the dust and air separating unit 320 are sequentially distributed on the main unit assembly 300 in a direction from the proximal end to the distal end of the main body 110 (a direction from the top to the bottom), or the dust and air separating unit 320, the main motor, and the battery pack are sequentially distributed on the main unit assembly 300.

Wherein, when the battery pack, the main motor and the dust-air separating unit 320 are sequentially disposed on the main assembly 300 in a direction from top to bottom, the main assembly 300 has an advantage of simple and compact structure. When the dust-air separating unit 320, the main motor and the battery pack are sequentially distributed on the main unit assembly 300 in the direction from top to bottom, the main unit assembly 300 can be better held on the traveling frame 200, and has the advantage of stable and reliable operation.

In this embodiment, please refer to fig. 9, the cleaning apparatus further includes a driving unit 400, and the driving unit 400 is configured to drive the traveling carriage 200 to move up and down on the body 110. The driving unit 400 at least includes a driving motor 420, and the battery pack of the host assembly 300 is used for supplying power to the driving motor 420 to drive the traveling carriage 200 to slide on the body 110. In the present embodiment, the driving unit 400 is a mechanism having a linear reciprocating function, such as a rack and pinion mechanism, a screw mechanism, and a linear module mechanism.

Referring to fig. 1, 7 and 8, the traveling frame 200 is disposed on the body 110 in a liftable manner by the driving unit 400. Wherein the running carriage 200 has at least a first working position and a second working position in the longitudinal direction of the fuselage body 110. In this embodiment, the traveling frame 200 is disposed between the first operating position and the second operating position of the body 110 in a liftable manner along the longitudinal direction of the body 110. Thus, the cleaning apparatus can change the positions of the traveling carriage 200 and the main unit assembly 300 according to the external environment, thereby achieving cleaning in both open and non-open environments. The open environment refers to the floor of a living room or a bedroom, and the non-open environment refers to the areas such as the bottom of a sofa, the bottom of a table and the like.

Further, referring to fig. 7, the first working position is distributed near the distal end of the main body 110; referring to fig. 8, the second operating position is located near the proximal end of the fuselage body 110. Of course, working positions such as a third working position and a fourth working position can be arranged between the first working position and the second working position, and the number of the working positions can be determined according to actual use conditions. In the present embodiment, only the first operating position and the second operating position are provided on the main body 110.

In the present embodiment, the fuselage body 110 is provided with one of the above-mentioned outlets corresponding to the first and second operating positions of the bridge 200, respectively. Referring to fig. 10 to 12, the two outlets are respectively defined as a first outlet 111 and a second outlet 112, wherein the first operating position corresponds to the first outlet 111 and the second operating position corresponds to the second outlet 112.

Further, the first outlet 111 is near the distal end of the body 110, and the second outlet 112 is near the proximal end of the body 110. That is, the first outlet 111 is located at a low position, the second outlet 112 is located at a high position, and the second outlet 112 is disposed above the first outlet 111. When it is desired to clean an open environment, the travel carriage 200 is maintained in the first working position; when the non-open environment needs to be cleaned, the traveling crane frame 200 is kept at the second working position, and at this time, the floor brush unit 120 can conveniently enter the non-open environment for cleaning.

Preferably, the first outlet 111 and the second outlet 112 are located on the extension of the same straight line. For example, when the outer wall of the body main body 110 has a cylindrical shape, the first outlet 111 and the second outlet 112 are located on the same bus line.

In this embodiment, as shown in fig. 10 to fig. 12, a first valve 1111 is slidably disposed at the first outlet 111, a second valve 1121 is slidably disposed at the second outlet 112, and both the first valve 1111 and the second valve 1121 are disposed on the outer wall of the main body 110. The outer wall of the main body 110 is further provided with a first valve adjusting mechanism 113 acting on the first valve 1111 and a second valve adjusting mechanism 114 acting on the second valve 1121.

Referring to fig. 13, the first valve adjusting mechanism 113 includes a first housing 1131 and a first valve compression spring 1132 accommodated in the first housing 1131. The first valve 1111 is biased by the first valve compression spring 1132 to tend to keep closing the first outlet 111.

Specifically, the first casing 1131 is disposed in a hollow manner, and a casing of the first casing 1131 is provided with a first through opening (not shown in the figure) for the first valve 1111 to pass through, and the first through opening is distributed near the first outlet 111 side. Two ends of the first valve compression spring 1132 are respectively abutted against the first casing 1131 and the first valve 1111, and the first valve compression spring 1132 is distributed closer to the far end of the main body 110 of the body than the first valve 1111. When the first outlet 111 is in a closed state, the first valve 1111 extends out of the first housing 1131. The first valve 1111 is provided with a limit convex edge 1112 for limiting, and the limit convex edge 1112 limits the maximum extension amount of the first valve 1111. When the first outlet 111 is in an open state, the first valve 1111 is retracted into the first housing 1131.

In this embodiment, referring to fig. 14, the second valve adjusting mechanism 114 includes a second housing 1141 and a second valve compression spring 1142 accommodated in the second housing 1141. The second valve compression spring 1142 is distributed closer to the proximal end of the body main body 110 than the second valve 1121. The second valve 1121 is biased by the second valve compression spring 1142 to tend to keep closing the second outlet 112. The second valve adjusting mechanism 114 and the first valve adjusting mechanism 113 have the same structure, and are not described in detail herein.

Having fully described the structure of the first and second valve adjustment mechanisms 113 and 114 above, those skilled in the art will appreciate the following movement:

when the host assembly 300 moves to the first working position along with the traveling carriage 200, the end of the distal end of the traveling carriage 200 abuts against the first valve 1111 and applies a toggle force to the first valve 1111 toward the distal end of the body 110, so as to force the first valve 1111 to retract into the first housing 1131, thereby switching the first valve 1111 from the closed state to the open state. That is, in the first operating position, the first valve 1111 opens the first outlet 111, and the second valve 1121 closes the second outlet 112. The air path switching of the dust gas can be realized by arranging the first outlet 111 and the second outlet 112, and the dust gas switching device has the advantage of convenience in use.

When the main unit assembly 300 moves from the first working position to the second working position along with the traveling carriage 200, the traveling carriage 200 is no longer abutted against the first valve 1111, and at this time, the first valve 1111 slides upward under the biasing force of the first valve compression spring 1132 to close the first outlet 111. When the traveling crane frame 200 moves to the second working position with the main frame assembly 300, the end of the proximal end of the traveling crane frame 200 abuts against the second valve 1121, and applies a pulling force to the second valve 1121 in a direction toward the proximal end of the main body 110, so that the second valve 1121 is switched from the closed state to the open state. That is, in the second operating position, the first valve 1111 closes the first outlet 111, and the second valve 1121 opens the second outlet 112.

In summary, when the traveling carriage 200 and the main unit assembly 300 move to the first working position, the first outlet 111 is in an open state and is communicated with the dust air inlet 230, and the second outlet 112 is in a closed state. When the traveling carriage 200 and the main unit assembly 300 move to the second working position, the second outlet 112 is in an open state and is communicated with the dust air inlet 230, and the first outlet 111 is in a closed state.

That is, when the traveling carriage 200 is operated to the first working position, the dust air sucked through the body main body 110 enters the main unit assembly 300 through the first outlet 111, and when the traveling carriage 200 is operated to the second working position, the dust air sucked through the body main body 110 enters the main unit assembly 300 through the second outlet 112.

In this embodiment, please refer to fig. 9, a brake structure 410 is disposed at an end of a lifting path of the traveling carriage 200, and the brake structure 410 is disposed on an outer wall of the main body 110. The brake structure 410 is used for stopping and limiting the traveling crane frame 200, so that the traveling crane frame 200 is stopped at the first working position or the second working position. Wherein, the brake structures 410 are arranged corresponding to the outlets on the main body 110. In this embodiment, the main body 110 is provided with a first outlet 111 and a second outlet 112, and the number of the braking structures 410 is also two. When the traveling frame 200 travels to the first outlet 111 and the second outlet 112, the brake structure 410 performs a braking limit.

The braking structure 410 includes a braking elastic member, and the end of the traveling frame 200 performs braking by pressing the braking elastic member. The braking elastic element can be a limiting block made of rubber, can also be a hydraulic buffer, and can also be other elastic elements with buffering functions.

In the present embodiment, referring to fig. 1, a control switch 131 is disposed on the handle 130 of the main body 110, and a main switch 330 is disposed on the main assembly 300. The host module 300 further has a main control board (not shown), and the host switch 330 and the main motor are electrically connected to the main control board.

Specifically, the main control board controls the on/off of the main motor. When the main motor is started, negative pressure is generated in the dust-gas separation channel; when the main motor is turned off, the negative pressure in the dust-gas separation channel disappears. The main control board controls the rotation direction of the driving motor 420, thereby implementing the ascending movement or descending movement of the carriage frame 200. A floor brush motor (not shown) is disposed in the floor brush unit 120, and the main control board controls the floor brush motor to be turned on or off.

When the main unit assembly 300 is mounted on the traveling crane frame 200, the control switch 131 and the main unit switch 330 are electrically connected to the main control board, and after the user triggers the control switch 131 or the main unit switch 330, the main control board can control the working states of the main motor, the driving motor 420 and the floor brush unit 120.

When the main unit assembly 300 is separated from the traveling rack 200, the control switch 131 is no longer electrically connected to the main control panel, and the user triggers the control switch 131 to control the operating state of the main motor, so that the main unit assembly 300 is used as a handheld vacuum cleaner alone.

It is to be understood that the above-described embodiments are only some of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments in the present invention, a person skilled in the art can make changes or changes in other different forms without creative work, and all should belong to the protection scope of the present invention.
