Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaner floor brushes, in particular to a flat joint structure of a floor brush. Background Art

[0002] When a vacuum cleaner floor brush is in use, it is usually connected to the vacuum cleaner body through an extension tube. When the joint of the extension tube is connected to the vacuum cleaner body, electric power is transmitted to the floor brush through a conductive terminal. For example, Chinese Patent CN109805827B discloses a mini vacuum cleaner with electric conduction to the floor brush and a cyclone dust separation structure. The mini vacuum cleaner includes a main machine assembly, a dust cup assembly, an extension tube assembly, and a lower body assembly connected in sequence. Terminal contact parts are provided at the connection parts between the main machine assembly, the dust cup assembly, and the extension tube assembly. The terminal groups above and below the extension tube assembly are connected by wires. After the lower body assembly is buckled with the extension tube assembly, the terminals thereon are in contact with the terminals on the extension tube assembly. A cyclone dust separation structure is provided inside the dust cup assembly.

[0003] The extension tube of the existing vacuum cleaner floor brush is usually a round tube, and the conductive terminal is located in the joint housing at the end of the extension tube to protect the conductive terminal. When the joint at the end of the extension tube is inserted into the vacuum cleaner body, it is not easy to align and contact the conductive terminal with the conductive sheet on the vacuum cleaner body, resulting in inconvenient use of the floor brush. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a flat joint structure of a floor brush to solve the problem of inconvenient alignment between the conductive terminal of the existing circular extension tube and joint of the vacuum cleaner floor brush and the vacuum cleaner body.

A pressing part is provided on the surface of the lock catch plate. A spring is provided on the back of the lock catch plate, and the position of the spring corresponds to the pressing part. A locking tongue part is also provided on the surface of the lock catch plate. Symmetrically arranged conductive terminals are provided on both sides of the receiving seat.

[0008] As a further description of the above technical scheme:

[0009] The housing includes an inner housing and an outer housing. One end of the inner housing extends into the extension tube, and the outer housing is fixedly installed on the inner housing. A clamping block is provided on the inner housing, and a through hole corresponding to the clamping block is provided on the extension tube.

[0010] As a further description of the above technical solution:

[0011] The outer housing is fixedly installed on the inner housing through bolts, and countersunk holes for installing bolts are provided on the outer housing.

[0012] As a further description of the above technical solution:

[0013] The pressing part is in the shape of a frustum of a cone with a narrower upper part and a wider lower part.

[0014] As a further description of the above technical solution:

[0015] Symmetrically arranged side baffles are provided on both sides of the lock catch plate, and connecting heads are provided on the side baffles. The connecting heads pass through the mounting through holes on the side wall of the storage seat.

[0029] Embodiment 1

[0030] Please refer to Figures 1-4 , the present invention provides a technical solution: a flat joint structure of a floor brush, including:

[0031] A floor brush body 1, on which an extension pipe 11 is provided, and the cross-section of the extension pipe 11 is rectangular;

[0032] A connector 2, which includes a housing 21, a lock catch plate 22 and a conductive terminal 23. The housing 21 is detachably installed at the end of the extension pipe 11. A receiving seat 211 for placing the lock catch plate 22 is provided on the housing 21. The lock catch plate 22 is rotatably installed in the receiving seat 211. A pressing part 221 is provided on the surface of the lock catch plate 22. A spring is provided on the back of the lock catch plate 22, and the position of the spring corresponds to the pressing part 221. A lock tongue part 222 is also provided on the surface of the lock catch plate 22. Symmetrically arranged conductive terminals 23 are provided on both sides of the receiving seat 211.

[0033] The floor brush body 1 is connected to the vacuum cleaner body through the connector 2 at the end of the extension tube 11, and power is supplied through the conductive terminal 23 on the connector 2. During the assembly of the connector 2 and the vacuum cleaner body, the lock plate 22 is pressed downward by the inclined surface of the lock tongue portion 222 as the connector 2 is plugged in and assembled. After the connector 2 is plugged in, the lock tongue portion 222 is reset upward under the action of the spring to achieve locking. On the contrary, the pressing portion 221 is pressed downward to unlock and the connector 2 is pulled out.

[0034] The shell 21 includes an inner shell 212 and an outer shell 213. One end of the inner shell 212 extends into the extension tube 11. The outer shell 213 is fixedly mounted on the inner shell 212. A block 2121 is provided on the inner shell 212. A through hole 111 corresponding to the block 2121 is provided on the extension tube 11.

[0035] The extension tube 11 extends between the inner shell 212 and the outer shell 213, is sleeved on the inner shell 212, and is engaged with the block 2121 on the extension tube 11 through the through hole 111, thereby hiding the installation structure of the connector 2 and effectively preventing the connector 2 from being separated from the extension tube 11.

[0036] The outer shell 213 is fixedly mounted on the inner shell 212 by bolts. The outer shell 213 is provided with countersunk holes 2131 for mounting the bolts, so that the inner shell 212 and the outer shell 213 can be detachably mounted, which is convenient for maintenance.

[0037] The pressing portion 221 is a truncated cone-shaped structure that is narrow at the top and wide at the bottom, so as to avoid interference between the pressing portion 221 and the receiving seat 211 when the locking plate 22 is pressed to unlock or reset, thereby ensuring a smooth unlocking process.

[0038] Symmetrically arranged side baffles 223 are provided on both sides of the lock plate 22. Connectors are provided on the side baffles 223. The connectors are passed through mounting holes 2111 on the side walls of the storage seat 211. The lock plate 22 is triangular to avoid affecting the rotation of the lock plate 22 when it is pressed down or reset upward.

[0039] The end of the locking plate 22 is provided with a notch 2231, and the notch 2231 is provided at the end of the side baffle 223. The side baffle 223 at the connector is separated from the locking plate 22, which is convenient for the deformation of the side baffle 223 at this location and for the installation and removal of the locking plate 22.

[0040] Working principle: The floor brush body 1 is plugged and assembled with the vacuum cleaner body through the connector 2 at the end of the extension tube 11. The extension tube 11 has a flat tube structure, and the connector 2 is correspondingly a flat connector, which is convenient for clarifying the position of the conductive terminal 23 on the connector 2 and aligning the conductive terminal 23 with the corresponding position of the vacuum cleaner body to avoid misoperation. On the other hand, the conductive terminals 23 are arranged on both sides of the receiving seat 211, so that the receiving seat 211 can effectively ensure the alignment of the conductive terminals 23 and effectively protect the conductive terminals 23 to avoid damage to the conductive terminals 23.

[0041] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
