Description

Technical Field

[0001] This utility model relates to the field of interface technology, and in particular to interface structures for vacuum cleaners. Background Technology

[0002] With the development of home appliance technology, vacuum cleaners, as a common cleaning tool, have been widely used in both home and commercial environments. Existing vacuum cleaners typically use various connectors and hoses for connection, but these hoses and connectors require disassembly for cleaning. Chinese patent "CN201820105573.4" discloses a vacuum cleaner that achieves cleaning by self-cleaning and improving sealing, reducing the number of times the pipe needs to be disassembled. However, it still cannot solve the practical problem of easy disassembly and quick replacement of quick connectors.

[0003] Therefore, a new interface structure for vacuum cleaners is needed to solve the above problems. Utility Model Content

When the connector unit is inserted into the mounting hole, the flange abuts against the inclined surface to expand the lower ends of the support arms outwards. When the flange passes the limiting head, the connector unit is limited by the limiting head. When the control unit is pressed down, the support arms are acted upon by the outer wall of the interface unit to expand the lower ends of the support arms outwards.

[0006] In the above scheme, preferably, the mounting hole includes a first segment and a second segment with different diameters, and the flange slides on the first segment against the second segment to achieve a limiting position.

[0007] In the above scheme, preferably, the perforations are symmetrically arranged on the interface unit, and the limiting heads are symmetrically arranged on the control unit.

[0008] In the above scheme, preferably, the control unit further includes a pressing block, which is located at the upper end of the support arm, and the interface unit is provided with a sliding groove that cooperates with the pressing block.

[0009] In the above scheme, preferably, the support arm is arc-shaped, the distance between the lower ends of the inner walls of the two support arms is appropriate to the outer diameter of the cylindrical part of the interface unit, and the distance between the upper ends of the inner walls of the two support arms is smaller than the outer diameter of the cylindrical part of the interface unit.

[0010] In the above scheme, preferably, the interface unit includes a first ring plate and a second ring plate, and the control unit is installed between the first ring plate and the second ring plate.

[0011] In the above scheme, preferably, the inclined surface is oriented towards the outer end of the mounting hole, and the flange is inserted to cooperate with the inclined surface.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1-6 The system includes a vacuum cleaner body 1, wherein the vacuum cleaner body 1 needs to be provided with an interface unit 2 and a connector unit 18 for the external passage. In this embodiment, the interface unit 2 connects the inside and outside of the vacuum cleaner body 1.

[0023] The interface unit 2 is located within the vacuum cleaner body 1 and connected thereto. The interface unit 2 includes a mounting plate 8, which is perpendicular to the interface unit body. In this embodiment, the mounting plate 8 is quadrilateral, and a connecting piece 9 extends from the mounting plate 8. The connecting piece 9 is parallel or nearly parallel to the interface unit 2 box, and the connecting piece 9 can be locked in the vacuum cleaner body 1 with a fixing member, which can be a screw.

[0024] The other part of the interface unit 2 is located on the outside of the vacuum cleaner body and is used in conjunction with the connector unit. The two are locked in a first state or unlocked in a second state through the control unit 3.

[0025] Specifically, the interface unit 2 is provided with a first annular plate 10 and a second annular plate 11, both of which have a diameter larger than that of the main body of the interface unit. Therefore, a certain space is left between them to form a cylindrical part 12, which is used to control the specific activities of the control unit 3.

[0026] Meanwhile, the control unit 3 includes two support arms 7 distributed on the left and right. The lower end of the support arm 7 is provided with a limiting head. The limiting head 4 provided at the lower end of the support arm 7 is positioned towards the support arm 7 to form a hook. The limiting head and the support arm 7 are symmetrically arranged in the control unit 3, wherein the outer wall of the support arm is arc-shaped, and the distance between the inner walls needs to be adapted to the cylindrical part 12.

[0027] Specifically, the distance between the lower ends of the inner walls of the two support arms 7 is adapted to the outer diameter of the cylindrical portion 12 of the interface unit 2. That is, the lower ends of the inner walls of the two support arms 7 are in contact with the cylindrical portion 12 without external force. Moreover, the distance between the upper ends of the inner walls of the two support arms 7 is smaller than the outer diameter of the cylindrical portion 12 of the interface unit 2. That is, when the lower ends of the inner walls of the support arms 7 are in contact with the cylindrical portion 12, there is still extra space between the upper ends of the inner walls of the two support arms 7 and the cylindrical portion 12.

[0028] The interface unit 2 also includes a through hole 5 corresponding to the limiting head 4. The limiting head 4 is set through the through hole 5. At the same time, the limiting head 4 or the supporting arm 7 is in an unlocked first state or a locked second state according to the position of the supporting arm 7. Specifically, there is a gap between the upper end of the two supporting arms 7 and the cylindrical part 12. When the control unit 3 is pressed and moved towards the cylindrical part 12, the two supporting arms 7 expand outward at the same time to make the limiting head 4 disengage from the through hole 5, so as to realize the unlocked first state.

[0029] Meanwhile, when the control unit 3 is in a state without external force, the limiting head 4 is placed through the through hole 5, that is, the lower ends of the two support arms 7 are reset to achieve the second locked state. In the embodiment, the material of the control unit is a deformable material, which can be a plastic part. Therefore, the support arms 7 can be reset in the state without external force.

[0030] The control unit 3 also includes a pressing block 6 located above the two support arms. The first annular plate 10 includes a sliding groove that cooperates with the pressing block. The pressing block is slidably disposed in the sliding groove to control the displacement of the control unit 3, that is, the pressing block 6 realizes the change between unlocking and locking.

[0031] The interface unit also includes a mounting hole 14, which includes a first segment and a second segment with different diameters, i.e., the diameter of the first segment is larger than that of the second segment. The through hole 5 is provided on the first segment and communicates with the mounting hole. The mounting hole 14 is used for the insertion and engagement of the connector unit 18.

[0032] The connector unit further includes a flange 16 with a diameter larger than that of the connector unit body. The flange 16, in conjunction with a limiting head, controls the two support arms. The limiting head is provided with... The flange slides on the first section against the second section to achieve a limiting position with the inclined surface 15. The inclined surface 15 is set towards the first annular plate 10, that is, the inclined surface 15 is set towards the outer end of the mounting hole 8. When the flange 16 slides in the mounting hole 14, the flange 16 and the inclined surface 15 cooperate, that is, the flange 16 and the inclined surface 15 abut against each other to make the lower end of the support arm 7 expand outward to be in the unlocked first state. At the same time, when the flange 16 passes the limiting head 4, the support arm 7 is limited by the limiting head 4 under the action of the material.

[0033] Meanwhile, the connector unit 18 also includes a locking block 17 with a diameter larger than that of the connector unit body. The locking block 17 is used to restrict the movement of the connector unit, that is, the locking block 17 stops at the interface unit 2 at the end of the movement.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
