Cleaning member for indoor vertical surface and ceiling and cleaning machine thereof

Technical Field

The invention relates to the technical field of household indoor washing and cleaning, in particular to a cleaning member for indoor vertical surfaces and ceilings and a cleaning machine thereof.

Background

The existing household cleaning machines are often used for cleaning the indoor floor, and are also called as sweeping robots. The prior art lacks a cleaning machine for cleaning the indoor vertical face and the ceiling, and cleaning the indoor vertical face and the ceiling is mainly carried out by manually using tools such as a broom, a mop and/or a brush. The mode has large workload, low efficiency and unsatisfactory cleaning effect.

Therefore, it is necessary to design a cleaning machine capable of cleaning an indoor vertical surface and a ceiling, which can release the manpower to the greatest extent, thereby realizing cleaning of the indoor vertical surface and the ceiling.

Disclosure of Invention

In view of the above, the present invention provides a cleaning machine capable of cleaning an indoor vertical surface and a ceiling, which can release manpower to the greatest extent, thereby cleaning the indoor vertical surface and the ceiling.

The first aspect of the present invention discloses a cleaning member for indoor facades and ceilings, comprising: a cleaning housing which is a cylindrical housing having a hollow interior; the side wall of the cleaning shell is provided with an open slot extending in the length direction of the cleaning shell; a driving lever which is built in the cleaning housing; the driving rod is a cylindrical cam body, and the outer peripheral surface of the driving rod is provided with a curve outline; a follower extending from the open slot into the cleaning housing, and an end of the follower within the cleaning housing being in contact engagement with the curved profile of the drive rod; a cleaning execution unit attached to the driven member at an outer side of the cleaning housing; the driving rod can be operated to rotate around the axis of the driving rod relative to the cleaning shell, and the guiding and limiting of the driven member are formed by means of the opening groove, so that the rotary motion of the driving rod can be converted into the linear motion of the driven member along the opening groove in the length direction of the cleaning shell, and the cleaning of the cleaning execution unit to different positions can be realized.

By means of the limit of the driven member (or called as a push rod of a cylindrical cam) by the open slot on the cleaning shell and the contact fit of the end of the driven member positioned in the cleaning shell and the curve outline of the driving shaft, when the driving shaft is driven to rotate, the rotation motion of the driving shaft can be converted into the linear motion of the driven member along the open slot in the length direction of the cleaning shell; since the cleaning execution unit is attached to the follower, this enables the cleaning execution unit to be driven to different positions in the length direction of the housing, thereby achieving cleaning of different positions (or "different heights").

Moreover, based on the structural design of the invention, the driven piece is inserted into the cleaning shell from the opening groove on the cleaning shell, so that the opening groove on the cleaning shell has guiding and limiting functions on the driven piece, and meanwhile, the end part of the driven piece positioned in the cleaning shell keeps constant contact fit with the curve contour of the driving shaft, so that the driven piece can be driven to conduct guiding displacement along the opening groove, is not easy to fall off, and has good working stability.

According to the cleaning member disclosed in the first aspect of the invention, the curved profile is configured to enable the follower to reciprocate linearly along the open groove in the length direction of the cleaning housing with continuous rotation of the drive lever.

This makes the driving of the movement of the cleaning execution unit in the present invention simple and easy to execute.

This can be achieved by providing a hyperbola on the drive rod, i.e. a first curve extending in a curved manner from the starting end (also referred to as the lower end) of the drive rod towards the end (also referred to as the upper end) of the drive rod on the outer circumferential surface of the drive rod, and a second curve formed at the end of the drive rod starting from the end point of the first curve at the end of the drive rod towards the starting end of the drive rod, i.e. the first curve and the second curve are connected at a location near the end of the drive rod, but are both free ends near the starting end of the drive rod. That is, the follower can be moved along the open slot from the beginning to the end of the drive rod by means of a first curve and then moved along the open slot from the end to the beginning of the drive rod by means of a second curve.

Fig. 19 shows a schematic structural view of the rotation and elevation driving mechanism.

Referring to fig. 16 to 19, in the cleaning machine of the present invention, the cleaning consumable cleaning unit 4 includes: a water container 401; a cleaning cylinder 402 arranged in the water container 401, a gap is arranged between the cleaning cylinder 402 and the water container 401, and a plurality of water holes for water to enter and exit are formed in the side wall of the cleaning cylinder 402; a rotating member 404 disposed within the cleaning cartridge 402 and operable to generate a rotation for swirling a body of water within the cleaning cartridge 402 to spin clean the cleaning consumables; a cleaning tray 403 is disposed in the cleaning cylinder 402 and is operable to be lifted up and down for being lifted up to approach the top cover of the cleaning cylinder 402 or the water container 401 after the completion of the rotary cleaning, so as to squeeze out water from the cleaning consumable after the rotary cleaning.

The steam case of the high-temperature steam generating unit 5 is attached to the main body casing of the machine main body, and water passage holes are provided at corresponding positions of the steam case and the main body casing. In specific use, water can be added through the water inlet portion 504 of the high temperature steam generating unit 55, and the added water can enter the main body housing through the steam housing, and then enter the water container 401 of the cleaning consumable cleaning unit 4 through the main body housing.

In a preferred embodiment, a water passage may be formed directly between the steam housing and the water container 401, so that the added water body can directly enter the water container 401 through the steam housing without re-entering the main housing.

The cleaning consumable cleaning unit 4 can work in an electrically controlled manner, and its specific control principle can be realized by the existing controller with a control chip, which belongs to the prior art and is not described here again.

When the cleaning consumable cleaning unit 4 is required to perform work, first, a cleaning consumable (e.g., a cleaning cloth or a cleaning brush body detached from a cleaning brush head) to be cleaned is placed on the cleaning tray 403, and then the cleaning consumable cleaning unit 4 is started. First, the rotating member 404 is operated to rotate, and the water body in the cleaning cartridge 402 is rotated by the rotation of the rotating member 404, thereby generating a vortex, and cleaning consumables on the cleaning tray 403 are cleaned by the rotating water body. After the cleaning is completed, the rotating member 404 is controlled to stop rotating. The cleaning tray 403 can then be controlled to be raised so that the cleaning tray 403 approaches the top cover of the water container 401. When the distance between the cleaning tray 403 and the water container 401 gradually becomes smaller, the cleaning consumable can be squeezed out by means of the top cover of the water container 401. After the squeezing out of the water is completed, the cleaning tray 403 can be controlled to descend downward. After the cleaning consumable member stops working, the user can open the cover body to take out the cleaning consumable which has been cleaned and has been squeezed out of the water on the cleaning tray 403.

In the present invention, the cleaning consumable cleaning unit 4 comprises a rotation and lifting driving mechanism, which comprises a clutch device 405 comprising an outer driven transmission member 406, a driving transmission member 407 and an inner driven transmission member 408 which are coaxially arranged in an inner sleeve; the driving transmission member 407 is located between the outer driven transmission member 406 and the inner driven transmission member 408, and the driving transmission member 407 is configured to form a power transmission with the outer driven transmission member 406 in forward rotation and to form a power transmission with the inner driven transmission member 408 in reverse rotation; the rotary member 404 is attached to an outer driven transmission 406.

In a preferred embodiment, the clutch device 405 is a dual ratchet clutch, wherein the driving transmission member 407 and the outer driven transmission member 406 form an outer driving ratchet clutch, and the driving transmission member 407 and the inner driven transmission member 408 form an inner driving ratchet clutch. Specifically, in the outer driving ratchet clutch, the driving member 407 is provided with an outer pawl 421 capable of telescoping, and an outer ratchet 420 is provided on an inner circumferential surface of the outer driven member 406, so that when the driving member 407 is driven to rotate forward, the outer pawl 421 on the driving member 407 is clamped against the outer ratchet 420 on the outer driven member 406, thereby driving the outer driven member 406 to rotate and further driving the rotating member 404 to rotate, and at this time, the driving member 407 is separated from the inner driven member 408, i.e., no transmission is formed between the driving member 407 and the inner driven member 408. An inner ratchet 418 is arranged on the inner side of the driving transmission member 407, and an inner pawl 419 which is matched and can extend and retract by a spring is arranged on the inner driven transmission member 408, when the driving transmission member 407 is driven to rotate reversely (the reverse rotation refers to the direction opposite to the rotation direction of the driving transmission member), the inner ratchet 418 on the driving transmission member 407 is clamped with the inner pawl 419 on the inner driven transmission member 408 to form transmission fit, so that the inner driven transmission member 408 is driven to rotate, and the cleaning tray 403 is driven to lift, and at the moment, the outer driven transmission member 406 is separated from the driving transmission member 407, namely, no transmission is formed between the outer driven transmission member 406 and the driving transmission member 407.

In the present invention, the driving transmission 407 is driven by means of a power device (e.g., a motor, not shown in the drawings), so that only the forward rotation and the reverse rotation of the power device need to be controlled to respectively perform the rotation operation of the rotating member 404 and the lifting operation of the cleaning tray 403.

In the present invention, the rotation and elevation driving mechanism further includes an elevation member including a transmission lever 409, a limit housing 412, a push block 413, and a tray connector 414, wherein a lower end of the transmission lever 409 is attached to the inner driven transmission member 408; the upper lever section of the transmission lever 409 is configured as a cylindrical cam lever body section 410, on the outside of which a lifting curve profile 411 is provided; the limit housing 412 is sleeved outside the cylindrical cam rod body section 410, and a bar-shaped limit groove 417 extending in the length direction thereof is provided on the side wall thereof; the bottom of the limit housing 412 is supported and connected to the side wall of the washing drum 402 by means of a support connection bar 415, and since the washing drum 402 is stationary, the limit housing 412 remains stationary, so that the push block 413 can be guided and limited by means of a bar-shaped limit slot 417 when the transmission lever 409 is rotated; the pushing block 413 extends into the limiting shell 412 from the strip-shaped limiting groove 417, and the end part of the pushing block 413 in the limiting shell 412 is in contact fit with the lifting curve profile 411 of the transmission rod 409; the upper part of the tray connecting piece 414 is fixedly connected with the cleaning tray 403, and the lower part is connected with the pushing block 413; when the inner driven transmission member 408 is driven to rotate, the transmission rod 409 rotates along with it, so that the rotation motion of the cylindrical cam rod body segment 410 is converted into the linear motion of the pushing block 413 along the strip-shaped limiting groove 417 under the guiding and limiting action of the strip-shaped limiting groove 417 on the pushing block 413, and the cleaning tray 403 can be driven to lift.

Preferably, in the present invention, the elevation curve profile 411 is configured to enable the pushing block 413 to reciprocate linearly in the length direction along the bar-shaped limit groove 417 with the continuous rotation of the transmission lever 409. The continuous rotation means that the transmission lever 409 rotates in the same rotation direction, that is, in the case where the transmission lever 409 does not need to change the rotation direction, the pushing block 413 can perform the linear reciprocating motion along the bar-shaped limit groove 417, thereby achieving the up-and-down lifting of the cleaning tray 403. Specifically, the construction of the lifting curve profile 411 may be designed with reference to the curve profile on the aforementioned drive lever.

That is, with the lifting member of the present invention, the lowering return of the cleaning tray 403 can be achieved without the need for the inner driven transmission member 408 to rotate in the opposite direction to the rotation direction thereof.

Furthermore, in a preferred embodiment, the bottom end of the limit housing 412 is mated with the rotating member 404 by means of a bearing element 416, in particular the bearing element 416 comprises an inner ring and an outer ring, the outer ring being attached to the rotating member 404 and the inner ring being connected to the bottom of the limit housing 412. This is so that when the rotating member 404 is operated to rotate, the limit housing 412 does not rotate or interfere, while the limit housing 412 forms a support by means of the rotating member 404.
