The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings. It is to be understood that the embodiments described herein are illustrative only and are not limiting upon the present invention.

Referring to fig. 1-3, in an embodiment of the present invention, a vacuum cleaner 100 includes a body assembly (not numbered), and a floor brush assembly 3 in fluid communication with the body assembly.

The up-down direction is not defined in a state where the cleaner 100 is normally placed, and may be referred to as the U direction in fig. 1. Specifically, the machine body assembly comprises a handle assembly 4, a power assembly 1 and a dust and air treatment assembly 2 which are arranged along the top-down direction. The power assembly 1 has a cylindrical housing, and the handle assembly 4 interferes with the upper end surface of the housing of the power assembly 1 and is fixedly held by the upper end surface and the body of the power assembly 1.

Referring further to fig. 1, the handle assembly 4 includes a grip portion 41 for facilitating gripping by a user and an extension tube 42 connected to the grip portion 41, the extension tube 42 extending downwardly and interfering with an upper end surface of the housing of the power assembly. Preferably, the extension tube 42 penetrates from the upper end surface and forms a holding with the power module 1. Preferably, the extension tube 42 is a telescoping tube. Preferably, the handle assembly 4 is provided with an electrical switch assembly 43, which may include a power switch, etc., and the electrical switch assembly 43 may be electrically connected with the power assembly 1 in a wired or wireless manner. Preferably, the handle assembly 4 is also provided with a physical switch 45 for switching the extension tube to the extended or retracted state. In other embodiments, the gripping portion of the handle assembly 4 and the extension tube may be a single gripping entity that directly interferes with the upper end surface.

In this embodiment, the floor brush assembly 3 includes a floor brush body, a brush roller disposed inside the floor brush body, a driving motor (not shown) for driving the brush roller, and a connecting member 5 pivotally movable relative to the floor brush body, wherein the floor brush body includes a receiving cavity for receiving the brush roller and an air inlet passage communicated with the receiving cavity. The air inlet channel penetrates through the floor brush body and the connecting piece 5. In other embodiments, the floor brush assembly 3 may be provided without the brush roller or the driving motor, and only the suction opening facing the bottom surface is opened, so that the surface cleaning mode is a pure suction mode.

Referring to fig. 2 and 3, the dust-air processing assembly 2 at least includes a dust cup 21 and a dust-air separating unit (not numbered) disposed at a middle position of the dust cup 21. In the preferred embodiment, the dirt and gas separation unit is fixedly connected relative to the power assembly 1, and the dirt cup 21 is removably connected relative to the dirt and gas separation unit.

The dust cup 21 includes a cylindrical cup body (not numbered) extending vertically and a dust cup cover 212 engaged with the cup body, and the dust cup cover 212 is disposed at the bottom of the dust and air processing assembly 2 and pivotally connected to the cup body. In the above preferred embodiment, after the body assembly is separated from the floor brush assembly 3, the dust cup cover 212 or the cup body can be opened or detached separately, that is, the user can open the dust cup cover separately according to the need of cleaning to clean the inside of the dust cup, or directly detach the cup body to clean the inside of the dust cup, optionally, the cup body is connected with the dust-air separation unit through the way of screw clamping.

As further shown in fig. 4 and 5, the flow direction of the air flow during normal operation of the vacuum cleaner defines an upstream and a downstream, the upstream of the dust and air processing assembly 2 at least includes a first air flow channel 61 and a second air flow channel 62, and when the vacuum cleaner is in operation, the first air flow channel 61 and the second air flow channel 62 are respectively opposite to the flow/blocking state of the dust and air processing assembly 2. That is, when the vacuum cleaner is in operation, the first air flow channel 61 and the dust and air processing assembly 2 are in a flow state, and the second air flow channel 62 and the dust and air processing assembly 2 are in a blocking state. It should be noted that in other embodiments, the first airflow channel 61 and the second airflow channel 62 can be selectively blocked off simultaneously when the vacuum cleaner is in the storage state, i.e. the non-operation state.

Specifically, the first air flow channel 61 is in fluid communication with the aforementioned floor brush assembly 3. In this embodiment, the first air flow channel 61 includes a first air duct penetrating through the dust cup cover 212 at the bottom of the dust cup and a flow guiding chamber 250 fluidly connected to the first air duct, the flow guiding chamber 250 has a flow guiding opening facing the upstream of the dust and air processing assembly 2, and the flow guiding chamber 250 guides the air flow in the first air duct to the upstream of the dust and air processing assembly 2 through the flow guiding opening. The air inlet passage of the floor brush assembly 3 is in fluid communication with the first air duct. It should be noted that in this embodiment, the first air duct is disposed at the middle position of the dust and air processing assembly 2 mainly in consideration of the aesthetic property of the overall layout of the cleaner body, and in other embodiments, the first air duct may be disposed along the outer side of the dust and air processing assembly 2, in which case the flow guide cavity passes through the outer shell of the dust and air processing assembly 2 to enter the upstream (not shown) of the dust and air processing assembly 2.

The second air flow path 62 is provided independently of the aforementioned first air flow path 61. The vacuum cleaner of the present invention includes at least one surface treatment attachment (not shown) which may typically be a pet brush, a flatus brush, a mite removing brush, or the like. The second airflow passage 62 may be in fluid communication with the accessories. Since the accessories are also required to be operated by the vacuum cleaner during daily cleaning, but in actual use, the frequency of the accessories is much lower than that of the floor brush assembly 3, the accessories are detachably arranged with the second airflow channel 62, and when the accessories are required to be used, a user can connect the accessories to the second airflow channel 62 for use. Through setting up two independent wind channels, on the one hand, all need the user to demolish the scrubbing brush subassembly when having avoided using the annex at every turn, on the other hand, because the work situation difference of above-mentioned annex and scrubbing brush has decided these annex and has needed bigger flexibility, sets up independent wind channel for these annexs, can be when optimizing the overall layout of organism better, do not influence the holistic pleasing to the eye of organism. Alternatively, the attachments may be directly connected to the second airflow passage 62, or may be indirectly connected to the second airflow passage 62 through bellows, hoses, and the like.

Specifically, in this embodiment, the second airflow channel 62 extends upward along the body assembly and penetrates into the body of the power assembly 1 from the inside of the body assembly, so as to provide an airflow opening (opening portion) at the upper half side of the entire body assembly to facilitate access to the accessories. The airflow opening may be provided in a side wall of the body assembly or an end wall of the body assembly remote from the floor brush assembly, the attachment being directly or indirectly connectable to the airflow opening. Because the accessory is usually held by a user when in actual use, and the height of the object to be processed facing the accessory is higher than the ground, the access position of the accessory is lifted, and the operation of the user can be more convenient. In this embodiment, a second airflow channel 62 extends along the body assembly in a direction away from the floor brush assembly 3. To allow for aesthetics of the overall arrangement, the second air flow passage 62 may extend to the end of the power module 1 and interface with the handle module as described above. Of course, in other embodiments, the airflow opening of the second airflow path 62 may be hidden in the housing of the body assembly, and a removable flap may be correspondingly left on the housing, and when the accessory is docked, the flap may be removed to dock with the second airflow path.

In this embodiment, the gripping portion of the handle assembly is removably connected to an extension tube that is at least partially in fluid communication with the second airflow passageway 62, so that the second airflow passageway 62 may be connected directly to the accessory or indirectly to the accessory via the extension tube.

Except for the situation described in the above embodiment, the second airflow channel may also be disposed to extend along the housing of the body assembly, and the other arrangements are similar to the situation of the above embodiment except for differences in appearance, so that detailed description is omitted here.

Referring to fig. 4 and 5, the vacuum cleaner of the present invention further includes a switching device (arrangement) to keep the blocking/flowing states of the first air flow channel 61 and the second air flow channel 62 opposite to each other when the vacuum cleaner is in operation. Since such a switching arrangement may have a plurality of schemes, it will be described below in terms of different embodiments.

The first embodiment is as follows:

the first air flow channel 61 comprises the first air duct and a flow guide port for communicating the first air duct to the upstream of the dust and gas processing assembly 2, the second air flow channel 62 comprises a second air duct, and one of the second air duct and the first air duct is movably arranged relative to the other of the second air duct and the first air duct; the first air flow channel 61 and the second air flow channel 62 switch the flow/blocking state by the relative movement of the first air-guide tube and the second air-guide tube. As shown in fig. 4 and 5, a first relative position (fig. 4) and a second relative position (fig. 5) are provided between the first airway tube and the second airway tube, in the first relative position, the first airway tube is communicated with the diversion port, the second airway tube is blocked by the body of the fuselage assembly (optionally, in other embodiments, the second airway tube may also be configured to be blocked by the first airway tube), in the second position, the second airway tube is communicated with the diversion port, and the first airway tube is blocked by the second airway tube (optionally, in other embodiments, the first airway tube may also be configured to be blocked by the body of the fuselage assembly).

When the user is in actual use, the first air duct can be promoted to move relative to the second air duct in a lifting mode, a pulling mode and the like, so that the blocking/flowing state change of the first air flow channel/the second air flow channel is switched. So that when one of the brush assembly 3 or the attachment is in use the other air flow passage is closed, loss of negative pressure is avoided and cleaning of the surface is enhanced.

Example two:

the first air flow channel 61 comprises a first air duct and a flow guiding cavity for fluidly connecting the first air duct to the upstream of the dust and air processing assembly, and the second air flow channel 62 comprises a second air duct, the second air duct is fluidly connected to the flow guiding cavity, and the flow guiding cavity comprises at least a three-way reversing valve (not shown) and a flow guiding opening facing the upstream of the dust and air processing assembly. The three-way reversing valve is respectively connected with the first air duct, the second air duct and the diversion port. The three-way reversing valve can be a manual valve or an electric valve.

When the user actually uses, the first air duct or the second air duct can be switched between the circulation of the first air duct or the second air duct and the flow guide opening in a manual or electric mode. So that when one of the brush assembly 3 or the attachment is in use the other air flow passage is closed, loss of negative pressure is avoided and cleaning of the surface is enhanced.

Example three:

the first air flow channel comprises a first air duct and a first air inlet valve (not shown) capable of blocking the first air duct, and the second air flow channel comprises a second air duct and a second air inlet valve (not shown) capable of blocking the second air duct; the dust collector has a first working state and a second working state, when the dust collector is in the first working state, the first air inlet valve is opened, the second air inlet valve is closed, the first air flow channel is communicated with the dust and air processing assembly, and the second air flow channel is blocked; and in a second working state, the first air inlet valve is blocked, the second air inlet valve is opened, the second air flow channel is communicated with the dust and air processing assembly, and the first air flow channel is blocked. The first air inlet valve and the second air inlet valve can be both manual valves or electric valves.

Unlike the two embodiments above, the first and second air flow passages may share the same flow guide opening to communicate with the upstream of the dust and air treatment assembly; the first air flow channel and the second air flow channel can also be respectively provided with a flow guide opening so as to be communicated with the upstream of the dust and gas processing assembly.

In a preferred embodiment, the first intake valve is an electric valve or a responsive valve. The body assembly at least comprises a storage position and a working position relative to the floor brush assembly 3, as shown in fig. 4 or 5, the dust collector is in a similar storage state, in which the relative position of the body assembly and the floor brush assembly is defined as the storage position, and when the dust collector is not in the storage state, the relative position of the body assembly and the floor brush assembly is defined as the working position. When the body assembly is in a stowed position relative to the floor brush assembly, the first air inlet valve is automatically closed. So that the state changing operation of the first air flow channel and the second air flow channel of the dust collector is simpler and more convenient.

Without being limited to the first, second, third or other preferred embodiments, optionally, the power supply/cut-off state of the floor brush assembly 1 is switched with the flow/blocking state of the first air flow channel, when the first air flow channel flows, the floor brush assembly is in the power supply state, and when the first air flow channel is blocked, the floor brush assembly is in the power cut-off state.
