Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a connection hose that is provided to connect a suction device to a suction barber tool that sucks hair debris at the same time as cutting hair.

[Conventional technology]

A suction barber tool in which a suction vibrator is attached to a barber tool body such as an electric hair clipper with its suction port facing the blade of the barber tool body, and a suction device such as a vacuum cleaner used in general households. is connected with a connecting hose so that the suction force of the suction device sucks up the cut hair waste at the same time as the hair is cut by the barber tool itself.
This method is known from Japanese Utility Model Publication No. 15 and Japanese Utility Model Application Publication No. 60-63172. In these conventional examples, there is no description of the specific structure of the connection hose, and
The suction port of the suction pipe provided in the suction hairdressing tool is elongated and narrowed along the blade of the suction hairdressing tool so as to face the blade.

[Problem that the invention seeks to solve]

The narrowed suction port as described above limits the amount of air that is sucked into the suction device along with the cut hair, but the amount of air sucked in by vacuum cleaners and other devices used as suction devices is quite large. , the air volume is insufficient for a vacuum cleaner, etc. In addition, since insufficient air volume causes the temperature of the motor of a vacuum cleaner to rise abnormally, there is a problem in that it is difficult to use the suction hairdressing tool for a long time to avoid such a situation. Note that if you make the suction port of the suction pipe larger, the above problem will not occur, but if you do that,
The suction performance of the cut hair becomes much worse, and
This is not a practical measure because the suction barber tool becomes larger and becomes difficult to handle.

[Means for solving problems]

In order to solve the above-mentioned conventional problems, the first invention according to the present application provides, at one end of the flexible hose body, a fitting tube that fits and connects to the hose connection part of the suction barber tool. In addition, a fitting cylinder is provided at the other end of the hose body to be fitted and connected to the suction end of the suction device, and at least one of these fitting cylinders is provided with suction means.

In addition to solving the above-mentioned conventional problems, the second invention according to the present application is to ensure a necessary suction air volume regardless of variations in dimensions of the fitting tube and the member fitting thereto. A fitting tube is provided at one end of the flexible hose body to fit and connect to the hose connection portion of the suction barber tool, and the other end of the hose body is provided to fit into the suction end portion of the suction device. At least one of these two fitting tubes is provided with a suction means, and the outer surface of one of the fitting tubes is provided with a hose connection portion of the above-mentioned suction hairdressing tool that is fitted therein. Alternatively, the suction device may include a stopper portion that limits fitting with the suction portion of the suction device to a depth at which at least a portion of the suction means is exposed.

[Effect]

The connection hose of the first and second inventions according to the present application has one fitting tube fitted into the hose connection part of the suction barber tool, and the other end fitting tube fitted into the suction end of the suction device. When the suction barber tool and the suction device are connected, the suction means provided in at least one of the fitting tubes is located downstream of the narrowed suction port of the suction barber tool. be done. Therefore, when the suction device is operated, apart from the air sucked in from the narrowed suction port of the suction barber tool,
Air is sucked into the connecting hose from the outside through the suction means, thereby making up for the lack of air sucked in through the constricted suction port, making it possible to use the suction hairdressing tool for a long period of time. In addition, since the connection hose of the second invention according to the present application is provided with a stopper part, if there are variations in the dimensions of the hose connection part or the suction end part that fits into the fitting tube provided with the stopper part, In this case, positioning through contact with the stopper portion can prevent the intake means from being fitted too deeply, where the intake means is completely closed, and at least a portion of the intake means can be exposed to ensure replenishment of the intake air volume.
