Detailed descriptions of known functions and known components are omitted in the present application in order to keep the following description of the embodiments of the present application clear and concise.

Referring to fig. 1 to 10, the embodiment of the application provides a cleaning head of a cleaning device, which comprises a housing 1 and a cleaning roller module 2 arranged on the housing 1.

The housing 1 is provided with a fitting chamber 12. The cleaning roller module 2 mounted on the housing 1 can be partially accommodated in the mounting chamber 12. For a cleaning head of a cleaning device employing a vacuum suction function, a suction port 13 for communicating with a fan is also provided on the housing 1. Under the action of the blower, the gas in the fitting chamber 12 is drawn away, thereby generating a negative pressure in the fitting chamber 12. The cleaning roller module 2 of the housing 1 is exposed to one side of the assembly chamber 12 to form a cleaning inlet. Dirt such as dust enters the assembly chamber from the cleaning inlet under the effect of the negative pressure and is output from the suction connection 13.

In the embodiment of the present application, the housing 1 includes a housing main body 11 and a first connection seat 14 and a second connection seat 15 oppositely disposed on the housing main body 11. The first and second coupling seats 14 and 15 are used to assemble the cleaning roller module 2 to the housing 1.

In the embodiment of the present application, the cleaning roller module 2 includes a driving assembly 21 and a hollow roller 22. The driving assembly 21 is fitted in the roller 22 for driving the roller 22 to rotate relative to the driving assembly 21. The cleaning roller module 2 is detachably connected with the shell 1. The cleaning roller module 2 as a whole can be assembled on the housing 1 or disassembled from the housing 1, and compared with the situation that the roller 22 is disassembled independently to move the whole axial length, the cleaning roller module 2 of the embodiment of the application only needs to move a smaller distance in the axial direction. The assembly and the disassembly are more convenient and faster, and the working efficiency is improved. Meanwhile, the cleaning roller module 2 is integrated, so that the situation that broken garbage such as hair enters the driving assembly 21 can be effectively reduced, and the cleanness and the high efficiency of the driving assembly 21 are guaranteed.

In the embodiment of the present application, the housing 1 is provided with a first connecting seat 14 and a second connecting seat 15, which are respectively used for matching with two ends of the cleaning roller module 2, so as to assemble the cleaning roller module 2 on the housing 1. Wherein, at the first end of the cleaning roller module 2, the driving component 21 is circumferentially and fixedly connected with the first connecting seat 14. At the second end of the cleaning roller module 2, the roller 22 is rotatably engaged with the second connecting seat 15. The roller 22 is rotatably engaged with the second connecting seat 15, the driving assembly 21 is circumferentially fixed with the first connecting seat 14, when the driving assembly 21 drives the roller 22 to rotate, the driving assembly 21 is fixed relative to the housing 1, and the roller 22 can rotate around an axis.

In the embodiment of the present application, in order to facilitate the detachment of the cleaning roller module 2, at least one of the first connecting seat 14 and the second connecting seat 15 can provide a moving space required when the cleaning roller module 2 is detached. One of the first and second coupling seats 14 and 15, which can provide a moving space required when the cleaning roller module 2 is disassembled, serves as a movable coupling seat. The articulated joints are movable relative to the housing body 11 to provide axial movement space for fitting or removing the scrub roller from the housing 1. One of the first connecting seat 14 and the second connecting seat 15 is a movable connecting seat, which can provide a moving space for the cleaning roller module 2 to be disassembled and assembled. In an exemplary embodiment, only the second connector holder 15 may be a movable connector holder.

Referring to fig. 2, 5 and 6, in the cleaning head of the cleaning apparatus provided in the embodiment of the present application, the cleaning roller module 2 includes a hollow roller 22 and a driving assembly 21 fitted in the roller 22. The driving assembly 21 is used for driving the roller 22 to rotate relative to the driving assembly 21. The cleaning roller module 2 is detachably connected to the housing 1 as a whole. In the embodiment of the application, the roller 22 and the driving component 21 form the cleaning roller module 2, and when the cleaning roller module 2 is assembled on the shell 1 or removed from the shell 1, only smaller axial displacement is needed, so that the assembly and the disassembly are more convenient and rapid.

In the embodiment of the present application, the specific manner of moving the movable connecting seat relative to the housing main body 11 is not limited. Referring to fig. 3 and 4, in an exemplary embodiment, the movable connection seat may be removable from the housing 1, thereby providing a space required when the cleaning roller module 2 is assembled to or removed from the housing 1. Referring to fig. 10, in another exemplary embodiment, the movable connection seat may also have a movable portion 32 capable of moving along the rotation axis of the drum 22 relative to the housing 1. By the movable portion 32 moving along the rotational axis of the drum 22, a space required when the cleaning roller module 2 is fitted to or removed from the housing 1 is provided.

Referring to fig. 3 and 4, in some embodiments, the movable coupling seat is detachably coupled to the housing body 11 to provide an axial movement space for the cleaning roller module 2. In the exemplary embodiment, after the movable connecting seat is removed from the housing body 11, the position of the movable connecting seat on the housing 1 is formed as an opening through which the cleaning roller module 2 can move in the axial direction. The movable connection holder detachably connected to the case main body 11 is not limited in the mounting manner. For example, the movable connecting base can be clamped with the shell body 11, connected by a screw piece and the like.

Taking the second connecting seat 15 as an example of a movable connecting seat, when the cleaning roller module 2 is disassembled, the cleaning roller module 2 moves towards the second connecting seat 15, and the movable part 32 is forced to move along the axial direction, so that a space is provided for disassembling the cleaning roller module 2. After moving a certain distance, the driving unit 21 is disconnected from the first connecting seat 14. The cleaning roller module 2 is tilted to form a certain angle with the assembled state, and the cleaning roller module 2 is reversely moved, so that the connection between the roller 22 and the second connecting seat 15 is released, thereby detaching the cleaning roller module 2 from the housing 1.

Referring to fig. 10, in some embodiments, the movable connection seat includes a movable portion 32 and an elastic member 33, the movable portion 32 can move in the axial direction, the elastic member 33 provides a force for keeping the movable portion 32 at the first position, and the movable portion 32 can move in the axial direction against the force of the elastic member 33 to provide an axial movement space for the cleaning roller module 2, and the movable portion 32 is kept at the first position when the cleaning roller module 2 is assembled on the housing 1.

Also taking the second connecting seat 15 as an example of a movable connecting seat, when the cleaning roller module 2 is installed, the roller 22 of the cleaning roller module 2 is connected with the second connecting seat 15 first, and then moves towards the direction of the second connecting seat 15, and the movable part 32 is forced to move along the axial direction, so that a space is provided for assembling the cleaning roller module 2. After moving a certain distance, the driving assembly 21 of the cleaning roller module 2 is opposite to the first connecting seat 14. The cleaning roller module 2 is moved towards the first connecting seat 14, so that the driving component 21 is circumferentially and fixedly connected with the first connecting seat 14, and the cleaning roller module 2 can be kept assembled on the shell 1 under the action of the elastic piece 33.

Referring to fig. 10, in the embodiment of the present application, the movable connection seat may further include a base 31. The base 31 has a slide chamber for accommodating the movable portion 32, and the movable portion 32 can slide along the slide chamber. An elastic member 33 is further disposed in the sliding cavity, and two ends of the elastic member 33 respectively act on the base 31 and the movable portion 32.

The base 31 and the case main body 11 may be of an integral structure or a separate structure. When the base 31 and the housing body 11 are separate structures, the base 31 may be fixedly connected to the housing body 11 by a screw or a snap.

When one of the first connecting seat 14 and the second connecting seat 15 is a movable connecting seat, the other connecting seat and the housing main body 11 may be an integral structure or a separate structure. The connection mode in the split structure includes screw connection, clamping connection and the like, which are not described herein.

Referring to fig. 4, 5 and 7, in some embodiments, there is a circumferential fixing structure between the driving assembly 21 and the first connecting seat 14. In a specific implementation, the connection manner of the driving assembly 21 and the first connection seat 14 may be a spline fit, so as to realize a circumferential fixed connection between the driving assembly 21 and the first connection seat 14. One of the first connecting seat 14 and the driving assembly 21 is formed with a socket portion, and the other is formed with a corresponding connecting portion. The connecting part is a connecting hole which is axially arranged. When the first connecting seat 14 and the driving assembly 21 are connected, the insertion portion is inserted into the connection portion in the axial direction. One of the first connecting seat 14 and the driving assembly 21 is formed with a positioning key 41, and the other is formed with a corresponding positioning groove 42. When the insertion part is inserted into the connection part along the axial direction, the positioning key 41 slides into the positioning groove 42, so that the circumferential fixed connection between the driving assembly 21 and the first connection seat 14 is realized. For example, the first connecting seat 14 is formed with an insertion portion having a positioning groove 42 on an outer peripheral surface thereof. The end of the driving unit 21 connected to the first connecting seat 14 has an axial connecting hole forming connection portion, and the inner circumferential surface of the connection portion has a positioning key 41. When the cleaning roller module 2 moves axially and the connecting portion of the driving assembly 21 is sleeved on the inserting portion of the first connecting seat 14, the positioning key 41 slides into the positioning groove 42 to fixedly connect the driving assembly 21 with the first connecting seat 14 in the circumferential direction. The specific arrangement of the positioning key 41 and the positioning groove 42 will be further described in the following embodiments with reference to the circumferential fixing structure.

In some embodiments, the first connecting seat 14 has a first conductive terminal 16, the driving assembly 21 has a second conductive terminal 24, the first conductive terminal 16 and the second conductive terminal 24 have a positive electrode and a negative electrode, respectively, and when the cleaning roller module 2 is assembled on the housing 1, the second conductive terminal 24 is electrically connected to the first conductive terminal 16, so that the power supply can provide power for the driving assembly 21. In the embodiment of the present application, the first connecting seat 14 and the driving assembly 21 are respectively provided with a conductive terminal, and when the cleaning roller module 2 is assembled on the housing 1, the conductive terminals arranged on the first connecting seat 14 and the driving assembly 21 are electrically connected, so that the power supply can provide power for the driving assembly 21. The first conductive terminal 16 and the second conductive terminal 24 can be separated from each other without affecting the detachment of the cleaning roller module 2 from the housing 1.

The power source for powering the drive assembly 21 may be a battery. The cleaning equipment is powered by the battery, and is free of cable drag when in operation, so that the cleaning equipment is more convenient to use. The battery as the power source may be various types of rechargeable batteries. Of course, the embodiment of the present application does not exclude an external power source to supply power to the driving assembly 21.

In some embodiments, the electrical connection of the first and second

conductive terminals

16, 24 includes at least one of a mating and an abutting. The splicing or butting electric connection mode is convenient for the disassembly and the assembly of the cleaning roller module 2. As long as the first conductive terminal 16 and the second conductive terminal have opposite positive and negative poles, the first conductive terminal 16 and the second conductive terminal 24 can be electrically connected or disconnected during assembly and disassembly.

In an exemplary embodiment, the positive and negative poles of the first conductive terminal 16 and the second conductive terminal may be electrically connected in the same manner. For example, the positive electrode and the negative electrode are in a plug-in connection mode or in an abutting connection mode.

Of course, the positive and negative electrodes of the first conductive terminal 16 and the second conductive terminal may also adopt different electrical connection modes. For example, one of the positive and negative electrodes is inserted, and the other is abutted.

The specific configuration of the plugging and the specific configuration of the abutment can be exemplified by the following embodiments.

Referring to fig. 8 and 9, in some embodiments, the positive pole and the negative pole of the first conductive terminal 16 and the second conductive terminal 24 are respectively coaxially arranged, and the axis of the positive pole and the axis of the negative pole of the second conductive terminal 24 are collinear with the rotation axis of the cleaning roller module 2. The positive and negative poles of the first conductive terminal 16 and the second conductive terminal 24 are respectively coaxially arranged and are collinear with the rotation axis of the cleaning roller module 2, when the cleaning roller module 2 is assembled, whether the positive pole and the negative pole of the first conductive terminal 16 and the second conductive terminal 24 respectively correspond or not does not need to be considered, after the driving assembly 21 is connected with the first connecting seat 14, the electrode positioned inside is inevitably connected with the electrode positioned inside, and the electrode positioned outside is inevitably connected with the electrode positioned outside.

For example, the first and second

conductive terminals

16 and 24 have a positive pole on the inside and a negative pole on the outside, which are coaxial. After the driving assembly 21 is connected to the first connecting seat 14, the positive electrodes of the first conductive terminal 16 and the second conductive terminal 24 are connected, and the negative electrodes are connected.

In the embodiment of the present application, the electrical connection modes of the coaxially disposed positive and negative electrodes may be the same or different.

Taking the example of the electrodes being plugged, one of the first conductive terminal 16 and the second conductive terminal 24 is configured as a cylindrical structure, and the inner and outer peripheral surfaces of the cylindrical structure respectively form a positive electrode and a negative electrode. The other electrode comprises an electrode hole and an electrode column positioned in the electrode hole, and the inner wall surface of the electrode hole and the outer wall surface of the column body respectively form a positive electrode and a negative electrode. After the driving assembly 21 is connected to the first connecting seat 14, the outer peripheral surface of the cylindrical structure is electrically connected to the inner wall surface of the electrode hole, and the inner peripheral surface of the cylindrical structure is electrically connected to the outer wall surface of the electrode column.

Take one of the positive and negative electrodes as an example, and the other one as an example. The inner part can be a plug. One of the first and second

conductive terminals

16, 24 is an insert and the other is a connector. Such as the manner in which the pins 242 and receptacles 162 are connected. The external one may be an abutment. Specifically, the following examples are provided to illustrate different connection methods for positive and negative electrodes.

Referring to fig. 8 and 9, in some embodiments, one of the positive and negative terminals of the first or second

conductive terminal

16 or 24 is the pin 242 or the socket 162 on the inside and the one on the outside includes the annular conductive sheet. For example, the first connector housing 14 has an insertion hole 162 at the inner portion and a first annular conductive sheet 161 at the outer portion, which are coaxially disposed. Correspondingly, the driving assembly 21 has an inner pin 242 and an outer second annular conductive plate 241, which are coaxially disposed. The pin 242 and the socket 162 may be opposite positive poles or opposite negative poles. When the driving assembly 21 is connected to the first connecting base 14, the pin 242 is inserted into the insertion hole 162, and the first annular conductive plate 161 abuts against the second annular conductive plate 241.

In another example, the first connector 14 may have the inner pin 242 and the outer first annular conductive plate 161, which are coaxially disposed. Correspondingly, the driving assembly 21 has a socket 162 corresponding to the pin 242, the socket 162 is disposed coaxially with the driving assembly 21, and another electrode on the driving assembly 21 may be a non-annular conductive sheet, and the distance from the socket 162 is equal to the radius of the first annular conductive sheet 161. When the driving assembly 21 is connected to the first connecting seat 14, there is no requirement for the corresponding relationship between the driving assembly 21 and the first connecting seat 14 in the circumferential direction, and after the driving assembly 21 is connected to the first connecting seat 14, the electrodes of the two are necessarily electrically connected.

In some embodiments, the resilient conductive member 163 is disposed on the annular conductive tab of one of the first conductive terminal 16 and the second conductive terminal 24. The elastic conductive member 163 is provided to ensure stable electrical connection when abutted.

In the embodiment of the present application, the elastic conductive member 163 may be selected from a conductive spring or a conductive elastic sheet.

Referring to fig. 6 and 7, in some embodiments, the first connecting seat 14 has a first guiding structure 141, the driving assembly 21 has a second guiding structure 211, and when the cleaning roller module 2 moves axially to connect the driving assembly 21 to the first connecting seat 14, the driving assembly 21 can rotate to a predetermined position relative to the first connecting seat 14 under the action of the second guiding structure 211 and the first guiding structure 141. In the embodiment of the present application, corresponding guiding structures are respectively disposed on the first connecting seat 14 and the driving component 21, and the driving component 21 moves along the axial direction to be assembled to the first connecting seat 14, so that the guiding structures between the first connecting seat 14 and the driving component 21 act to enable the driving component 21 to rotate to a specific position relative to the first connecting seat 14. This configuration can simplify assembly of the cleaning roller module 2 without regard to whether the first and second

conductive terminals

16 and 24 correspond or not and without regard to whether a circumferential fixing structure (e.g., a key groove structure) between the first connecting seat 14 and the driving assembly 21 corresponds or not, and the driving assembly 21 is guided to a specific corresponding position with respect to the first connecting seat 14 by the guide structure. The position may be a position corresponding to the first and second

conductive terminals

16 and 24, or a position corresponding to a circumferential fixing structure between the first connection seat 14 and the driving assembly 21.

The first guide structure 141 is disposed on the first connecting seat 14, and the second guide structure 211 is disposed on the driving assembly 21, so that the specific configurations of the electrodes on the first conductive terminal 16 and the second conductive terminal 24 can be selected more widely without increasing the assembly difficulty. In the exemplary embodiment, the positive and negative poles are configured as pin 242 receptacles 162. For example, two insertion holes 162 are formed on the first connecting seat 14, and two insertion pins 242 are formed on the driving member 21. Taking the pins 242 on the driving assembly 21 as an example, the positions of the two pins 242 are not particularly required, and may be symmetrically arranged with respect to the axis or randomly arranged. The guide mechanism enables the electrodes on the first and second

conductive terminals

16 and 24 to be aligned.

Referring to fig. 6 and 7, in some embodiments, one of the first guide structure 141 and the second guide structure 211 is a guide groove, and the other is a guide block. In the embodiment shown in fig. 6, the first guiding structure 141 of the first connecting seat 14 is a guiding groove. The two wall surfaces of the guide groove are arranged in opposite spiral shapes, so that the guide groove is gradually reduced along the assembling direction. In this embodiment, the cleaning roller module 2 moves axially, so that when the driving assembly 21 is assembled to the first connecting seat 14, the guide block slides along the wall surface of the guide groove, and the driving assembly 21 rotates relative to the first connecting seat 14 until the guide block slides to the end point of the guide groove.

In the embodiment of the present application, the first guiding structure 141 may be a guiding groove, and the second guiding structure 211 may be a guiding block. The first guide structure 141 may be a guide block, and the second guide structure 211 may be a guide groove. Taking the example where the first connecting seat 14 has an insertion portion and the driving unit 21 has a connection portion, a guide groove is provided on the outer peripheral surface of the insertion portion, and a guide block is provided on the inner peripheral surface of the connection portion.

In the embodiment of the present application, a circumferential fixing structure is provided between the first connecting seat 14 and the driving assembly 21.
