Abstract

PURPOSE:To facilitate replacement of a heater, by detachably holding the other ends of connector pins by connectors which are fitted to a main body, as well as to hold a heater by one ends of connector pins which are insulatedly held by a heater holder incorporatig a burner. CONSTITUTION:Connector pins 23 are electrically insulatedly held by a heater holder 18, which is provided to the end part of the case 1 of a main body, in which a tank 3 to store combustible gas, fitted with a nozzle 7, is incorporated in a portable combustion apparatus, used for a dressing tool to curl one's hair, for instance. The heater holder 18 is made of an electrically insulating material, having a burner 9 inside of it, which is connected to the nozzle 7. The other ends of pins 23 are elastically held detachably, by connectors 26 which are fitted to the case 1, by the intermediary of elastic pieces 26', as well as to hold a heater 19 by one end of the pins 23. Gas from the tank 3, passing through the nozzle 7, can be injected from a burner 9, mixed with the air, fed from an intake port 10. A heater unit C can easily be replaced by pulling out the pins 23.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a combustion device used in portable equipment, etc., which allows a heater to be attached and detached, improves its replaceability, and facilitates repair and cleaning.2-7 It is.

An embodiment of the present invention will be described below with reference to the accompanying drawings. The figure shows a beauty device for curly hair.
It consists of a main body housing functional parts and a curling part B that curls the hair. The main body case 1 is covered with a main body cover 2, and inside there is a tank 3 for storing combustible gas and a pressure regulator 4 for controlling the gas pressure.
is installed. A nozzle stand 5 is attached to the pressure regulator 4, and a nozzle 7 is provided via a nozzle holder 6. The nozzle 7 is connected to a burner 9 via a pipe 8. The burner 9 is provided with an intake port 1o to take in outside air. In the main case 1,
The switch knob 12 attached to the switch base 11 is pushed up by a spring 13, and the switch terminal 14, which moves up and down in accordance with the vertical movement of the switch knob 12, is also attached to the switch base 11. There is. The switch terminal 14 has a contact portion 15 at its tip, and faces the dedicated portion 17 of the switch board 16.S, -:.

Ru.

In the above configuration, the combustible gas discharged from the tank 3 passes through the pressure regulator 4 and is sent to the nozzle stand 6. It passes through the nozzle holder 6 and comes out from the nozzle 7. The combustible gas is supplied by moving the switch base 11 forward and pulling the nozzle 7 forward to open the valve.

The combustible gas discharged from the nozzle 7 enters the burner 9 through the pipe 8, takes in air through the intake port 10 by the Venturi effect, and is ejected from the burner 9 as a mixture of air and combustible gas. .

The tip of the burner 9 is located in a heater holder 18 formed into a multi-cylindrical shape made of electrically insulating material provided at the end of the main body case 1. Therefore, the mixed gas passes through the heater holder 18 to the first end of the heater holder 18.
This corresponds to catalyst 2o.

The first catalyst 2o and the second catalyst 21 are held by a catalyst holder 22, and a heater 19 is located between them.

The heater 19 is insulated and supported by the heater holder 18 (connector bin 2317) - supported at the blade end b
Ru. The other end of the connector bin 23 is the heater holder 1
8, and its protruding end is received by a connector 26 attached to the main body case 1. The connector 26 has an elastic piece 26', and elastically supports the connector pin 23 in a detachable manner. Then, the heater 19 moves the switch base 11 forward to pull up the nozzle 7 that opens and closes the combustible gas, and when the switch knob 12 is pushed down, the contact part 15 of the switch terminal 14 moves downward, and the switch board 16 becomes conductive. 17 and connects the connector pin 23. Connector 26. A closed circuit is formed through the lead wire 27, and the mixed gas is raised to a temperature at which the mixed gas is catalytically combusted by the heater 19. The mixed gas is passed through the heater 19 and the 16th catalyst 2o whose temperature has been raised and the second catalyst 2.
1, the catalyst is combusted and generates thermal energy, which increases the temperature of the curl pipe 24 placed on the outside.
Then, the temperature of the brush 25 outside the pipe is raised to a temperature suitable for curling the hair. The exhaust gas after combustion is discharged to the outside through the opening 29 of the curl pipe 240 and the curler clip 28.

Note that there is a terminal 3 inside the main body cover 2 in parallel with the tank 3.
A battery 30 is installed between 1.32 and 32.

The terminal 32 is connected to a heater circuit via a lead wire 33. A cap 36 is removably provided at the end of the main body cover 2, and a cylinder insertion port 37 is provided in the cap 36 facing the combustible gas injection part 36. The cap 36 is attached to the mounting portion 3 by compressing the gripping portion 39.
8 to attach and detach the main body cover 2. The cylinder 4o is used to inject gas into the tank 3 by inserting its nozzle 41 into the insertion port 37. A combustible gas diffusion member 43 is provided inside the heater holder 18 and has a plurality of holes 44 .

A portion of the heater will be explained in detail with reference to FIG.

The heater 19 is a ceramic ring heater boulder 18
After being inserted into the connector bin 22, it is fixed by welding to the connector bin 22, which is fixed with a heat-resistant adhesive 46.
2 can be freely inserted into the connector 26 fixed to the main body case 1 by the elasticity of the elastic piece 26' so that it is always electrically connected, and can be freely removed so that the heater unit part C can be replaced. It has become. by this,
Since the ζ-tar 19, the first catalyst 2o, and the second catalyst 21 can be freely replaced and inserted without changing their positional relationship, the heating performance is stable and the heater is resistant to impact. No force is applied directly to the wire, reducing the risk of wire breakage. Further, a diffusion member 43 is provided in the mixed gas passage of the heater holder 18, but this is provided so that the combustible gas hits the first catalyst 20 after being sufficiently mixed with air.

As is clear from the above embodiments, the combustion apparatus of the present invention has the following features:
Since a portion of the heater can be freely attached and detached, it is easily replaceable and easy to repair and clean, making it extremely effective as a combustion device.
