In the present application, where the contrary is not intended, the use of directional words such as "upper, lower, top and bottom" is generally with respect to the orientation shown in the drawings, or with respect to the component itself in the vertical, perpendicular or gravitational direction; likewise, for ease of understanding and description, "inner and outer" refer to the inner and outer relative to the profile of the components themselves, but the above directional words are not intended to limit the invention.

Example 1

Referring to fig. 1, the present embodiment provides a cleaning mechanism 10, which is suitable for being installed with a negative pressure generator of a cleaning device to clean a surface to be cleaned, so that dirt on the surface to be cleaned is separated from the surface to be cleaned under the negative pressure of the negative pressure generator. The surface to be cleaned may be a floor surface, a wall surface, or a surface of an object to be cleaned, which is not specifically limited herein and is determined according to actual conditions.

In order to facilitate the cleaning of the narrow gap space such as the bottom of the sofa or the corner or the like by the user during the cleaning work, so as to improve the cleaning efficiency of the cleaning mechanism 10, the cleaning device is provided with an auxiliary cleaning mechanism 20 for cleaning the narrow gap space.

The auxiliary cleaning mechanism 20 can be independently arranged, and at this time, when the narrow gap space needs to be cleaned, the user can detach the cleaning mechanism 10 from the negative pressure generator and mount the auxiliary cleaning mechanism 20 with the negative pressure generator. However, the above-described operation causes the user to frequently attach and detach the cleaning mechanism 10 and the auxiliary cleaning mechanism 20, and therefore, the auxiliary cleaning mechanism 20 detachably attached to the cleaning mechanism 10 is carried along.

Referring to fig. 3 to 5, the cleaning mechanism 10 includes a housing 1, the housing 1 has a receiving cavity 13, and the receiving cavity 13 is adapted to detachably mount an auxiliary cleaning head 201 of the auxiliary cleaning mechanism 20, so as to detachably mount the auxiliary cleaning mechanism 20 and the cleaning mechanism 10.

In the prior art, the auxiliary cleaning head 201 and the cleaning mechanism 10 are usually assembled and disassembled by the engagement of the groove and the projection. For example, the auxiliary cleaning head 201 is provided with a projection, and the accommodating cavity 13 is provided with a groove. At this time, the accommodating chamber 13 of the housing 1 is completely opened to facilitate the installation and removal of the cleaning head 201 and the accommodating chamber 13. When the auxiliary cleaning mechanism 20 is installed in the abutting connection with the cleaning mechanism 10, the auxiliary cleaning head 201 can be installed in the accommodating cavity 13 only by engaging the protrusion with the groove. However, the grooves and the protrusions need to be accurately butted during the installation process, and a large force needs to be applied to separate the auxiliary cleaning mechanism 20 from the cleaning mechanism 10 during the disassembly and assembly process, which is inconvenient.

In order to solve the above technical problem, the cleaning mechanism 10 further includes a telescopic assembly 3 and a locking assembly 2, the telescopic assembly 3 is disposed at the bottom of the accommodating cavity 13, and the locking assembly 2 is connected with the housing 1. The lock assembly 2 is disposed at the rear side of the accommodation chamber 13 with the moving direction of the cleaning mechanism 10 as the front side. It should be noted that, in the present embodiment, when the auxiliary cleaning head 201 is located in the accommodating cavity 13, the front side of the accommodating cavity 13 abuts against the front side of the auxiliary cleaning head 201. Therefore, when the locking assembly 2 applies a locking force to the rear side of the auxiliary cleaning head 201, the auxiliary cleaning head 201 can be locked in the receiving chamber 13.

Wherein, the front side of the accommodating cavity 13 is provided with an insertion opening arranged towards the rear side for the front side of the auxiliary cleaning head 201 to be inserted into the insertion opening, so that the front side of the auxiliary cleaning head 201 is abutted against the front side of the accommodating cavity 13.

As described above, the receiving chamber 13 is formed on the housing 1, and therefore, the housing 1 has the protrusion provided at the front portion of the receiving chamber 13, which is located above the front portion of the receiving chamber 13 and matches with the outer shape of the auxiliary cleaning head 201 to receive the front portion of the auxiliary cleaning head 201 and prevent the front portion of the auxiliary cleaning head 201 from moving within the receiving chamber 13. Meanwhile, the rear side portion of the accommodating chamber 13 is opened to facilitate the disassembly and assembly of the auxiliary cleaning head 201 and the accommodating chamber 13. That is, the housing 1 is not provided above the rear portion of the accommodation chamber 13.

As can be seen from the foregoing, the auxiliary cleaning head 201 is detachably mounted in the accommodating chamber 13, and thus the auxiliary cleaning head 201 and the accommodating chamber 13 can be switched between the locked state and the unlocked state.

When the cleaning device is in a locked state, the auxiliary cleaning head 201 is embedded into the accommodating cavity 13, the telescopic assembly 3 is pressed by the auxiliary cleaning head 201 to store energy, and the locking assembly 2 applies locking force to the rear end of the auxiliary cleaning head 201 to force the auxiliary cleaning head 201 to be kept in the accommodating cavity 13; when the cleaning head is in the unlocking state, the locking assembly 2 cancels the locking force, and the auxiliary cleaning head 201 is popped upwards from the accommodating cavity 13 by the elastic force generated by the stored energy released by the telescopic assembly 3.

It can be seen that the locking assembly 2 is arranged at the rear side of the accommodating cavity 13, so that the locking assembly 2 can lock the auxiliary cleaning head 201 installed in the accommodating cavity 13, and the installation between the auxiliary cleaning head 201 and the accommodating cavity 13 is more stable. In addition, in the installation process, a part of the auxiliary cleaning head 201 does not need to be aligned with a part of the accommodating cavity 13, and the operation of a user is convenient.

Simultaneously, be provided with flexible subassembly 3 in holding chamber 13, this flexible subassembly 3 when locking subassembly 2 will assist cleaning head 201 and hold chamber 13 and remove the locking, the elasticity that its energy storage produced can provide the auxiliary force for the dismantlement of assisting cleaning head 201 and holding chamber 13, and it is more laborsaving convenient to dismantle.

In one embodiment, the locking force is a holding force, and the holding force is suitable for limiting the auxiliary cleaning head 201 to move away from the accommodating cavity 13 so as to be separated from the accommodating cavity 13.

Specifically, the locking assembly 2 includes a force applying member 21 movable relative to the housing 1 and a holding member 22 connected to the force applying member 21, and the holding member 22 moves along with the movement of the force applying member 21 and then holds or separates from the rear end of the auxiliary cleaning head 201 embedded in the accommodating cavity 13, so as to switch the auxiliary cleaning head 201 between the locking state and the unlocking state.

For example, the driving force drives the force applying member 21 to move towards a side away from the housing 1 to drive the abutting member 22 to separate from the rear side of the accommodating cavity 13, and at this time, the auxiliary cleaning head 201 is installed in the accommodating cavity 13 and is in an unlocked state. The force applying member 21 moves toward a side close to the housing 1 until the abutting member 22 is brought into abutment with the rear side of the auxiliary cleaning head 201, so as to be in a locked state.

The force application member 21 moves under the action of the driving force, so that the force application member 21 can reset when the driving force is removed, the locking assembly 2 further comprises a first elastic member 23, the first elastic member 23 is connected with the force application member 21 and the shell 1, and always applies elastic force to the force application member 21, so that the force application member 21 drives the abutting member 22 to tend to keep abutting against the rear end of the auxiliary cleaning head 201.

As can be seen from the foregoing, the urging member 21 is movable relative to the housing 1. For example, the force applying member 21 can rotate relative to the housing 1 through the rotating shaft 24, and the first elastic member 23 is sleeved on the rotating shaft 24. At this time, the first elastic member 23 is a torsion spring.

The first end of the first elastic element 23 abuts against the shell 1, and the second end of the first elastic element 23 abuts against the force application element 21; the force applying member 21 rotates under the action of the driving force, the second end rotates towards the first end to enable the first elastic member 23 to store energy, the driving force is cancelled, and the force applying member 21 resets under the elastic action of the elastic member.

For another example, the biasing member 21 is movable relative to the housing 1, one end of the first elastic member 23 is connected to the housing 1, and the other end of the first elastic member 23 is connected to the biasing member 21. At this time, the first elastic member 23 is a tension spring or a compression spring.

The urging member 21 is moved in a direction away from the housing 1 by the driving force to deform the first elastic member 23, and after the driving force is cancelled, the urging member 21 is moved toward the housing 1 by the elastic force to be reset.

In another embodiment, the locking force may also be a plugging force. Accordingly, in this embodiment, the locking assembly 2 includes a plug member which is provided on the housing 1 at the rear side of the accommodating chamber 13 and is rotatably connected to the housing 1. In order to fix the auxiliary cleaning head 201 in the accommodating cavity 13, a slot is arranged on one of the auxiliary cleaning head 201 and the plug-in unit, and a plug-in sheet matched with the slot in an insertion manner is arranged on the other of the auxiliary cleaning head 201 and the plug-in unit. When the auxiliary cleaning head 201 is placed in the accommodating cavity 13, the slot and the insertion sheet are aligned, so that the alignment is not required to be adjusted manually by a user, and the auxiliary cleaning head 201 is conveniently installed and fixed in the accommodating cavity 13 by the user.

The rotation of the plug-in unit is the same as the rotation of the force applying unit 21, and will not be described herein.

In other embodiments, the locking force may also be a clamping force or the like. Correspondingly, in this embodiment, the locking assembly 2 further comprises two clamping members, which may be provided, located at the rear side of the receiving chamber 13 and rotatably connected to the housing 1. The two clamping members form a clamping space to clamp the rear side of the auxiliary cleaning head 201 therein, achieving fixation. Similarly, the rotation mode of the clamping member is the same as the rotation mode of the force applying member 21, and is not described herein again.

As mentioned above, the retractable assembly 3 is disposed at the bottom of the accommodating cavity 13 and is pressed by the auxiliary cleaning head 201 to store energy. Therefore, the housing 1 further has a through hole communicating with the accommodating chamber 13, the through hole is disposed at the bottom of the accommodating chamber 13, and at least a part of the telescopic assembly 3 is disposed in the through hole and is movable in the height direction along the through hole. At least part of the telescopic assembly 3 is accommodated through the through holes, so that even if the telescopic assembly 3 is completely contracted by the abutting pressure of the auxiliary cleaning head 201, one end of the auxiliary cleaning head 201 is still tilted, and the stability of the auxiliary cleaning head 201 and the accommodating cavity 13 after installation is influenced. In the present embodiment, the through hole is provided at the rear side of the accommodation chamber 13 to be disposed close to the locking assembly 2. In other embodiments, the through hole may be disposed at other positions of the accommodating cavity 13, and is not specifically limited herein, depending on the actual situation.

Specifically, the telescopic assembly 3 includes a contact member 31 and a second elastic member 32. Wherein the contact member 31 is movable in the height direction with respect to the accommodating chamber 13, and is adapted to contact with the bottom of the auxiliary cleaning head 201 when the auxiliary cleaning head 201 is inserted into the accommodating chamber 13. Wherein the height direction is a direction vertically perpendicular to the moving direction of the cleaning mechanism 10.

The second elastic member 32 is located between the housing 1 and the contact 31, and is deformed by the movement of the contact 31. The contact piece 31 moves under the pressing action of the auxiliary cleaning head 201 to compress the second elastic piece 32, and when the auxiliary cleaning head 201 is in the unlocking state, the elastic force of the second elastic piece 32 drives the contact piece 31 to reset.

In order to make the overall structure of the cleaning mechanism 10 more compact, the contact member 31 has a cavity 311, the housing 1 further includes a guide member 14 protruding from the inner wall of the housing 1 toward the through hole, one end of the second elastic member 32 is disposed in the cavity 311, and the other end of the second elastic member 32 is fitted over the guide member 14. That is, in the present embodiment, a part of the second elastic member 32 is accommodated in the cavity 311.

In order to further fix the auxiliary cleaning head 201 in the accommodating cavity 13 when the auxiliary cleaning head 201 is installed in the accommodating cavity 13, the cleaning mechanism 10 further comprises a limiting component 4 connected with the housing 1. The position-limiting assembly 4 includes a first position-limiting member 41 and a second position-limiting member 42, the first position-limiting member 41 and the second position-limiting member 42 are respectively disposed at two sides of the accommodating cavity 13 and located at the front side of the locking assembly 2 to prevent the auxiliary cleaning head 201 from being displaced along a first direction, and the first direction is horizontally perpendicular to the moving direction of the cleaning mechanism 10.

Preferably, the first limiting member 41 and the second limiting member 42 are integrally formed with the housing 1, so that the overall structure of the cleaning mechanism 10 is more compact. That is, the first limiting member 41 and the second limiting member 42 are formed by protruding upward from two sides of the housing 1 forming the accommodating cavity 13, and the heights of the first limiting member 41 and the second limiting member 42 do not hinder the assembly and disassembly of the auxiliary cleaning head 201 and the accommodating cavity 13.

That is, the auxiliary cleaning mechanism 20 includes an auxiliary cleaning head 201, and the auxiliary cleaning head 201 is detachably mounted in the housing chamber 13 formed in the housing 1 of the cleaning mechanism 10. In this embodiment, when the auxiliary cleaning head 201 is installed in the accommodating cavity 13, the auxiliary cleaning head and the accommodating cavity are electrically connected in a conventional manner, which is not described herein again.

The housing 1 includes a main body 11 and a connecting portion 12 connected to the main body 11, the connecting portion 12 is located at a rear side of the main body 11, and an accommodating cavity 13 is formed between a part of the main body 11 and a part of the connecting portion 12. The body 11 connected to the connecting portion 12 has a convex portion protruding upward, and the upper end of the connecting portion 12 is lower than the upper end of the convex portion in the height direction, and the connecting portion 12 communicates with the convex portion, so that an accommodating chamber 13 is formed between the connecting portion 12 and the convex portion.

The connecting portion 12 includes a mounting body 121 and a fixing body 122 having a receiving cavity 123, the receiving cavity 123 has an opening, and the mounting body 121 is received at least partially in the receiving cavity 123 through the opening, thereby achieving mounting with the fixing body 122. Then, the accommodation chamber 13 is formed specifically between the mounting body 121 and the convex portion.

Further, in the present embodiment, the front side of the mounting body 121 is further optionally provided with a protrusion, which is adapted to the shape of the protrusion and is located in the protrusion, so as to further enable the front side of the auxiliary cleaning head 201 mounted in the receiving cavity 13 to abut against the inner wall of the protrusion.

The retractable element 3 of the above embodiment 1 is at least partially accommodated in the accommodating cavity 123 through the through hole, and the position-limiting element 4 of the above embodiment 1 is integrally formed with the fixing body 122.

The main body 11 further has an extension 111, the extension 111 extends from the rear side of the main body 11 to a direction away from the main body 11, and the connection portion 12 is disposed on the extension 111 and movably connected to the main body 11. The movable connection between the connection part 12 and the body part 11 is specifically as follows: the connecting portion 12 is rotatably connected to the extending body 111 to rotate in a first direction, which is horizontally perpendicular to the moving direction. It is noted that when the auxiliary cleaning head 201 is installed in the accommodating cavity 13, the auxiliary cleaning head 201 can rotate along with the accommodating cavity 13 and the connecting portion 12.

A main air duct 15 is formed in the housing 1, and the main air duct 15 is communicated with the accommodating cavity 13. That is, the main duct 15 is formed on the connecting portion 12, and an air outlet of the main duct 15 is provided toward the accommodating chamber 13 and communicates with the accommodating chamber 13. Specifically, the main duct 15 is formed on the mounting body 121, and the main duct 15 communicates with the dirt inlet of the body portion 11.

The auxiliary cleaning head 201 is provided at its bottom with a suction opening 204, the suction opening 204 communicating with the air outlet of the main duct 15. The auxiliary cleaning mechanism 20 further comprises a handheld shell 202 connected with the auxiliary cleaning head 201 and a negative pressure generator arranged in the handheld shell 202, wherein a secondary air duct 203 is formed in the handheld shell 202, the auxiliary cleaning head 201 is further provided with an outlet 205 communicated with the suction port 204, and the outlet 205 is communicated with the inlet end of the handheld shell 202.

Wherein the hand held housing 202 is rotatably connected to the outlet 205 in the moving direction of the cleaning mechanism 10. The connecting part 12 of the cleaning mechanism 10 is rotatably connected with the extending body 111, the handheld shell 202 of the auxiliary cleaning mechanism 20 is rotatably connected with the auxiliary cleaning head 201, and the rotating directions of the two parts are different, so that the overall flexibility of the cleaning device is improved, and when the auxiliary cleaning mechanism 20 is used alone for cleaning, the narrow gap space can be sufficiently cleaned; when the auxiliary cleaning mechanism 20 and the cleaning mechanism 10 are installed for cleaning, the cleaning mechanism 10 is not separated from the surface to be cleaned under the rotating action of the two positions, and the operation of a user is facilitated, so that the overall cleaning efficiency of the cleaning device is ensured.

When the auxiliary cleaning head 201 is installed in the accommodating chamber 13, dirt on the surface to be cleaned enters the main air duct 15 in the housing 1 and enters the auxiliary cleaning head 201 through the air outlet and the suction opening 204 of the main air duct 15. When the auxiliary cleaning head 201 is removed from the accommodating cavity 13, the auxiliary cleaning head 201 cleans the surface to be cleaned directly, and dirt enters the auxiliary cleaning head 201 from the suction opening 204 directly.

In order to facilitate the cleaning of large dirt particles when the auxiliary cleaning mechanism 20 is used alone, the suction opening 204 occupies at least half of the area of the bottom to form a large-area suction opening 204 for large dirt particles to enter. When the auxiliary cleaning mechanism 20 is mounted on the cleaning mechanism 10, and the auxiliary cleaning head 201 is in the locked state to ensure the cleaning efficiency of the cleaning device as a whole, the suction opening 204 completely covers the air outlet of the main air duct 15, so as to prevent the strength of the negative pressure from being weakened by communicating with the main air duct 15.
