Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaner hoses, in particular to a vacuum cleaner hose that can be quickly connected. Background Art

[0002] A vacuum cleaner is mainly composed of three parts: dust collection, dust collection, and dust filtration. It generally includes a series commutator motor, a centrifugal fan, a dust filter (bag), and dust collection accessories. The vacuum cleaner can remove dust mainly because its "head" is equipped with an electric exhaust fan. There is a wind impeller on the rotating shaft of the exhaust fan. After power is turned on, the exhaust fan will generate a high suction and pressure at a speed of 500 revolutions per second. Under the action of suction and pressure, the air is discharged at a high speed, and the air in the dust collection part of the front end of the fan continuously replenishes the air in the fan, causing an instantaneous vacuum inside the vacuum cleaner, forming a negative pressure difference with the external atmospheric pressure. Under the action of this pressure difference, dust-containing air is inhaled. Dust and other debris enter the dust filter bag through the carpet or floor brush, long pipe, elbow, hose, and hose connector in turn. Dust and other debris are retained in the dust filter bag. After the air is purified by the filter, it is discharged from the tail of the body.

[0003] When using the existing vacuum cleaner hose, it is not convenient for users to quickly connect the hose to other accessories (such as a round suction nozzle, an extension tube, and a floor brush, etc.). A straight tube is commonly fixed to the hose head, and the straight tube is directly plugged into the connection hole of other accessories. After multiple plugging and unplugging, the connection is likely to become loose, resulting in air leakage or other accessories falling off, affecting normal use.

[0004] Therefore, the existing technology has defects and needs to be improved. Utility Model Content

[0005] The purpose of the utility model is to solve the problems in the prior art that it is inconvenient for users to quickly replace other accessories and the connection is easy to loosen, and to propose a vacuum cleaner hose that can be quickly connected.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A quick-connect vacuum cleaner hose comprises a first pipe, one end of which is fixedly provided with a second pipe via a bellows, and further comprising: a fixing plate for connecting to the negative pressure end of the vacuum cleaner, fixedly provided on the other end of the first pipe; a fixing seat for connecting an accessory, fixedly provided on the end of the second pipe away from the bellows, an adapter seat being rotatably provided on the fixing seat, and a limiting portion being provided on the adapter seat for limiting the falling off of the accessory.

[0008] In order to facilitate the connection of other accessories with the adapter seat, preferably, a rotating groove is opened in the fixed seat, and an annular seat is rotatably arranged in the rotating groove. One end of the annular seat extending out of the rotating groove is fixedly connected to the adapter seat, and a first sealing ring is fixedly arranged on the annular seat, and the first sealing ring is abutted against the inner wall of the rotating groove. A plug-in tube is fixedly arranged on the end of the adapter seat away from the fixed seat, and a second sealing ring is fixedly arranged on the outer wall of the plug-in tube.

[0009] In order to prevent the accessory from loosening or falling, the limiting part further includes a card tube fixedly arranged on the plug-in tube, a limiting slot is provided on the card tube, a baffle is fixedly provided at the mouth of the limiting slot, and a limiting block is fixedly provided in the accessory to engage with the limiting slot.

[0010] In order to achieve quick assembly and disassembly, the limiting portion further includes a magnetic ring fixedly arranged on the adapter seat, and a magnetic block magnetically attracted to the magnetic ring is fixedly arranged on the end face of the accessory connecting pipe.

[0011] Furthermore, the limiting portion includes a clamping block fixedly arranged on the adapter seat, and a clamping groove in an annular structure is provided on the end surface of the accessory connecting pipe, and the clamping block is engaged with the clamping groove.

[0012] Preferably, a plug-in plate is fixedly provided at one end of the fixing plate away from the first pipe, a guide groove is provided on the plug-in plate, and a connecting groove is provided on the end of the fixing plate close to the first pipe, and a limit block is slidably provided on the vacuum cleaner, and the limit block extends into the connecting groove.

[0013] Compared with the prior art, the present invention provides a vacuum cleaner hose that can be quickly connected, which has the following beneficial effects:

[0014] 1. This quick-connect vacuum cleaner hose can reduce the twisting of the bellows by rotating an adapter on the fixed base. A plug-in tube is fixed on the adapter to facilitate plug-in connection with other accessories. A clamping tube is fixed on the plug-in tube to improve the connection effect between the plug-in tube and the accessories, reduce the risk of accessories loosening or even falling off, and realize quick replacement of other accessories, improving the user experience.

[0015] 2. The quick-connect vacuum cleaner hose is conveniently connected to accessories by fixing a plug-in tube on the adapter. In addition, a second sealing ring is fixed on the plug-in tube, which not only improves the sealing effect between the accessory connecting pipe and the plug-in tube, but also increases the friction between the plug-in tube and the inner wall of the connecting pipe, further improving the connection strength and reducing the risk of loosening.

[0016] The parts not involved in this device are the same as the existing technology or can be implemented by using the existing technology. The utility model is convenient for plugging and connecting with other accessories by fixing a plug-in tube on the adapter, and a card tube is fixed on the plug-in tube, which can improve the connection effect between the plug-in tube and the accessories, reduce the risk of the accessories loosening or even falling off, and can realize the rapid replacement of other accessories, thereby improving the user experience.
