Description

Technical Field

[0001] The present invention relates to the technical field of vacuum cleaners, and more specifically to a fitting connector for the air suction port of a vacuum cleaner. Background Art

[0002] As pets become increasingly important in people's lives, pet grooming and hair care have also become people's daily behaviors. As a result, many pet-related care devices have been invented. For example, the Chinese utility model patent with the publication number CN218736565U discloses a pet hair grooming device connected to a vacuum cleaner with UV disinfection and sterilization functions. During the process of grooming the pet's hair, this pet hair grooming device can not only suck away the pet's loose hair through an external vacuum cleaner, but also disinfect and sterilize the pet's skin and hair and eliminate parasites. In addition, there are also many pet care devices such as pet hair clippers, pet foot grinders, and pet nail clippers with air suction functions. However, the above devices all need to be equipped with a separate vacuum cleaner device to collect garbage or loose hair, and they all need to be powered by the vacuum cleaner device to be used. Moreover, the volume of the vacuuming device is relatively large, increasing the packaging and transportation costs of such products. Although there are also many accessories that are powered by electricity themselves, this requires electrical components such as batteries and main board circuits to be built into each replaceable accessory connected to the vacuum cleaner, which will greatly increase the product cost.

[0003] Nowadays, basically every family already has a vacuum cleaner with strong suction, but its actual utilization rate is not high, and there is no external power supply mechanism to achieve extended functions. If another pet care device with an air suction function is purchased, it will inevitably conflict with the functions of the vacuum cleaner, resulting in unnecessary waste. Summary of the Invention

[0004] In view of this, the present invention provides a fitting connector for the air suction port of a vacuum cleaner, aiming to solve the problems existing in the prior art.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions:

[0006] An accessory connector for a vacuum cleaner suction port, comprising: a double-wire corrugated hose; a first docking head and a second docking head are respectively provided at both ends of the double-wire corrugated hose; a hose housing is sleeved outside the first docking head; a first air duct cavity housing is sleeved inside the hose housing; one end of the first air duct cavity housing is docked with the first docking head; a connection component is provided at one end of the first air duct cavity housing away from the first docking head; a battery and a controller are provided on the outer wall of the first air duct cavity housing; an external accessory housing is sleeved outside the second docking head; a second air duct cavity housing is sleeved inside the external accessory housing; one end of the second air duct cavity housing is docked with the second docking head; an external terminal is provided on the second air duct cavity housing; the external terminal and the battery are respectively connected to both ends of two steel wires inside the double-wire corrugated hose through power lines.

[0007] Preferably, the hose housing includes a first housing and a second housing; the second housing is connected to the first housing by bolts, and the second housing is arranged corresponding to the battery; the first air duct cavity housing is connected to the first housing by bolts.

[0008] Preferably, a first annular groove is formed by inward depression on the outer surface of the first docking head; a first annular boss adapted to the first annular groove is provided on one side of the first housing close to the first docking head; the first housing is sleeved outside the first docking head through the cooperation of the first annular boss and the first annular groove.

[0009] Preferably, a first rotation limit boss is provided on the outer wall of one end of the first docking head close to the first housing; a first stop block corresponding to the first rotation limit boss is provided on the inner wall of the first housing.

[0010] Preferably, the controller includes a control button and a control main board; the control button and the battery are both electrically connected to the control main board.

[0011] Preferably, a USB charging interface electrically connected to the battery is provided on the hose housing.

[0012] Preferably, the connection component includes a threaded sleeve and a soft rubber sleeve; an annular baffle is provided at one end of the first air duct cavity housing away from the double-wire corrugated hose; the threaded sleeve is threadedly connected to the outside of the first air duct cavity housing; the threaded sleeve is arranged on one side of the hose housing away from the double-wire corrugated hose; the soft rubber sleeve is sleeved on the outside of the first air duct cavity housing; the soft rubber sleeve is arranged between the threaded sleeve and the annular baffle.

[0013] Preferably, anti-slip protrusions are provided on the outer wall of one side of the threaded sleeve close to the double-wire corrugated hose.

[0014] Preferably, an installation boss is provided on the outer wall of the second air duct cavity housing; an installation hole is provided inside the installation boss; the external terminal is inserted into the installation hole.

[0015] Preferably, an annular mounting plate is provided on one side of the mounting boss close to the double-wire corrugated hose; the external fitting housing is connected to the side of the annular mounting plate close to the double-wire corrugated hose by bolts.

[0016] The present invention has achieved the following technical effects compared with the prior art:

[0017] 1) The fitting joint of the present invention has a simple structure and is convenient to use. One end can be adapted to the detachable air outlet of a household vacuum cleaner, and the other end can be connected to the air duct of expansion fittings such as a pet clipper, a pet foot grinder, and a pet nail clipper for daily pet care, such as a grooming device disclosed in CN218736565U. Since the fitting joint is itself electrified, it can be adapted to the detachable air outlet of a household vacuum cleaner to meet the work of sucking garbage. In addition, there is no need to set up mechanisms such as a power supply and a main board at the expansion fitting end, and any fitting can be replaced and used.

[0018] 2) By setting a threaded sleeve and a soft rubber sleeve, when in use, one side of the soft rubber sleeve is inserted into the air suction port of the household vacuum cleaner, and the threaded sleeve is rotated. The threaded sleeve squeezes the soft rubber sleeve, causing the soft rubber sleeve to deform and expand, thereby firmly fixing the fitting joint inside the air suction port of the household vacuum cleaner. Thus, the fitting joint can be adapted and fixedly connected to the air suction port of any household vacuum cleaner, ensuring airtightness at the docking position while ensuring docking with the household vacuum cleaner.

[0019] 3) By rotatably sleeving the first housing on the outside of the first docking head and rotatably sleeving the external fitting housing on the outside of the second docking head, relative rotation of the double-wire corrugated hose with the first housing and the external fitting housing can be achieved, thereby improving the operation convenience of the device.

[0020] 4) By setting a first rotation limit boss, a first stop block, a second rotation limit boss, and a second stop block to limit the rotation angle of the double-wire corrugated hose, the power cord can be prevented from being broken when the double-wire corrugated hose is rotated.
