Description

  The present invention relates to a diffuser that vaporizes and diffuses a drug.

  Conventionally, a diffuser has been used when vaporizing and releasing a liquid medicine contained in a medicine bottle (for example, Patent Document 1).

  The diffuser body of the diffuser is provided with a heater for heating the suction core of the set medicine bottle, and configured to heat the medicine sucked up by the suction core and increase the transpiration efficiency. Has been.

An air inlet is provided in the lower part of the side surface of the diffuser body, and is configured to take air from below from the heater. Thereby, the air taken in from the air intake port is heated by the heater to generate an updraft, and can be diffused from the transpiration port established in the upper part.
JP 2002-200155 A

  However, in such a diffuser, the path length from the air inlet to the heater is long, and the circulation efficiency is poor.

  This invention is made | formed in view of such a conventional subject, and it aims at providing the diffuser which can improve the circulation efficiency of air.

In the diffusion device of the present invention to solve the above problems, the diffuser body container body is set, a heating unit for heating the wicking core of said container body, and transpiration from the wicking core In a diffuser provided with a volatilization hole for volatilizing the drug to the outside and an air intake for taking air into the diffuser body, the air intake is at a height position where the heating unit is provided. while Ru is provided between the height position where the volatilization hole is provided, in the diffuser body, a slide plate for varying the opening area of intake the air by sliding along the inner surface of the diffuser body Provided on the slide plate is a facing surface that faces the inner surface and forms a flow path between the inner surface and is disposed between the air intake and the heating unit by the facing surface. Constructed a baffle.

  In other words, the air intake for taking air into the diffuser body is provided between the height position of the heating section for heating the suction core of the container body and the height position of the volatilization hole. Compared to the case where the inlet is provided below the diffuser body, the distance from the air intake to the heating unit can be shortened.

  For this reason, the path length from the air intake port to the heating unit can be shortened, and the circulation efficiency until the air taken in from the air intake port is heated by the heating unit and released from the volatilization hole is increased. .

Further , a baffle plate is provided between the air intake and the heating unit, and even when a foreign object is inserted into the air intake, contact with the heating unit is prevented. .

Further , the diffuser body is provided with a slide plate that is slid along the inner surface of the diffuser body, and the opening area of the air intake port can be varied by the slide plate. Thereby, the amount of air taken in from the air intake is adjusted, and accordingly, the volatilization amount is adjusted from the volatilization hole.

  The slide plate is provided with a facing surface that is opposed to the inner side surface and forms a flow path between the inner side surface in the open state of the air intake port. A baffle plate is configured.

  Thereby, space saving is achieved compared with the case where the slide plate and the baffle plate are individually provided.

  Moreover, the baffle plate can be slid together with the slide plate by providing the slide plate with the baffle plate that can be a sliding obstruction factor of the slide plate. Thereby, the slide plate can be slid while maintaining the foreign matter insertion preventing effect by the baffle plate.

Above there was to the present onset light diffuser described, by shortening the path length from the air intake to the heating unit, the air taken from the inlet the air is heated by the heating unit volatilization Circulation efficiency up to discharge from the hole can be increased.

  Thereby, volatilization efficiency can be improved.

Further, between the front Symbol air inlet and the heating unit, by providing the baffle plate, even when the foreign object is inserted into inlet the air is possible to prevent contact to the heating unit it can.

  Thereby, the generation | occurrence | production of the disorder | damage | failure which may arise in the said heating part and its periphery can be prevented beforehand.

Furthermore, it is possible in this that by sliding the slide plate for varying the opening area of the air intake to adjust the amount of air taken in from intake the air.

  Thereby, the volatilization amount from the said volatilization hole can be adjusted.

  And since the said baffle plate was comprised by providing the opposing surface which forms a flow path between this slide plate in the said slide plate while facing the inner surface of the said diffuser main body, the said slide plate and the said Space saving can be achieved compared with the case where a baffle plate is provided separately.

  In addition, the baffle plate can be slid together with the slide plate by providing the slide plate with the baffle plate that can be a sliding obstruction factor of the slide plate. Thereby, the slide plate can be freely slid while maintaining the foreign matter insertion preventing effect by the baffle plate.
