Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a wax applicator for use in 1d skis.

Conventional Structure and Problems Conventionally, in this type of wax applicator, as shown in FIG. A thermostat 1-4 was installed to control the temperature. The melted wax in the melting tank 3 is pulled up into the opening/closing punch 6 by pressing the opening/closing button 6 downward, and the wax is drawn up into the wax outlet hole 7.
I try to make it flow more towards the waxed surface. However, this system using electricity as a heat source can only be used in places with a power source, such as indoors, and is not easy to use as ski equipment that is frequently used outdoors.

However, devices that use solid fuel as a heat source and can be used outdoors are already in use, as shown in Figure 2. In this method, solid fuel 8 is put into a combustion chamber 9 and burned to heat the application section 10 and melt and apply the wax 11. With this configuration, the temperature of the application section 10 cannot be controlled. First, it is difficult to provide the optimum temperature for each type of wax in situations where the ambient temperature changes. In addition, as shown in FIG.
However, none of these devices are equipped with a temperature control mechanism and burn with a flame, which may blow out under windy conditions, making it difficult to burn properly. It was difficult.

Purpose of the Invention The present invention solves these conventional problems and provides a cordless ski that maintains stable combustion and has a temperature control function that allows waxing to be performed at the optimum temperature for each type of wax. A wax applicator is provided.

Structure of the Invention The wax applicator of the present invention includes a tank storing liquefied petroleum gas fuel, a gas flow adjustment valve 19 for controlling the flow rate of gas discharged from the tank, and a gas flow adjustment valve 19 connected to the gas flow adjustment valve. an ejection nozzle, a combustion chamber containing a catalyst for combusting the fuel gas emitted from the gas ejection nozzle, a base serving as a waxing surface and a wax melting tank provided in thermal relationship with the combustion chamber; A temperature adjustment plate having spring properties is attached to the upstream side of the fuel gas flow with respect to the catalyst arrangement position, and one end is attached to the temperature adjustment plate located on the catalyst side, and the other end is in contact with the gas flow rate adjustment valve. The combustion chamber is equipped with a bimetal that has been adjusted and a temperature adjustment rod that adjusts the temperature by displacing the temperature adjustment plate, and the configuration of the temperature adjustment plate, bimetal, and temperature adjustment rod causes catalytic combustion to occur in the combustion chamber. When the base surface temperature rises, the bimetal also heats and bends, and when the set temperature is reached, the gas flow adjustment valve in contact with one end of the bimetal is activated to shut off the gas flow, and when the temperature drops below the set temperature, the gas is turned on again. is used to control the temperature of the base surface. In addition, when the temperature adjustment plate is displaced by operating the temperature adjustment rod, the bimetal connected to it is also displaced at the same time, and the contact status between the gas flow rate adjustment valve and the bimetal ~ changes, making it possible to vary the set temperature. This is what I did.

DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In FIGS. 4 and 5, 14 is a tank for storing liquefied petroleum scum, and 16 is a pressure regulator, which are connected to the tank 14 via a vibrator 16 and a shutoff valve 17. 18 is an opening/closing knob for operating the shutoff valve 17; 19;
is a gas flow rate adjustment valve that controls the gas flow rate in and out of the tank 14, and is connected to the outlet of the pressure regulator 15.

Reference numeral 20 denotes a gas ejection nozzle, which is connected to the gas flow rate adjustment valve 19 via a pipe 21. 22 is an injector, which is arranged to maintain a constant pressure N1# with the gas jet nozzle 20, and following the injector 22, the mixing pipe 2
There are 3. Combustion chamber 2 connected to mixing pipe 23
4 is the wax melting tank 26 and the waxing surface.
gas combustion catalyst 27, porous gas diffusion plate 28
The combustion chamber 24, melting tank 26, and base 26 are thermally connected to each other. The bimetal 29 for temperature control has an L-shape, and one end is welded and attached to the temperature adjustment plate 30 having spring properties, and the other end is brought into close contact with the gas flow rate adjustment valve 19. In addition, the temperature adjustment plate 3
0 is attached to the protrusion 26a on the base surface inside the combustion chamber 24, the tip is exposed outside the combustion chamber 24, and the bimetal 29
The temperature adjustment plate 3Q is installed in such a way that the bimetal 29 is located in the combustion chamber 24, and the bimetal 29 is closer to the catalyst than the temperature adjustment plate 30, and the temperature adjustment plate 3o is installed more uniformly than in the combustion chamber 24. Installed at a distance.

Furthermore, it has a temperature adjustment rod 31 that comes into contact with the temperature adjustment plate 30 outside the combustion chamber and displaces it in the vertical direction, and converts the rotational movement of the temperature adjustment knob 330 into vertical movement via the temperature adjustment screw part 32. I'm taking it. 34 is a spark plug for starting combustion, 35 is a handle, 36 is an opening/closing rod that controls the outflow and stop of melted wax, 37 is an opening/closing rod knob, 38 is a wax outlet hole, 39 is wax, and 40 is an igniter. , 41 is the ignition valve Δ2 attached to the opening/closing knob 18, and 41 is the exhaust gas.

To explain the operation in the above configuration, when the opening/closing knob 18 is rotated, the shutoff valve 17 is operated, and the liquefied petroleum gas in the tuck 14 is guided into the 1-force regulator 15 through the pipe 16. The vapor pressure of liquefied petroleum gas changes with changes in room temperature, reaching 7 to 8 y/ad at 40° C. atmosphere. Therefore, in order to obtain stable/-8 combustion, a constant secondary pressure is obtained by the pressure regulator 16. The gas that has passed through the pressure regulator 15 passes through the gas flow rate adjustment valve 19.
, the gas is ejected from the nozzle 20 following the pipe 21.

200 cc/min to 300 cc/min is required for the output of scum n6, and the secondary pressure of the pressure regulator 15 is 0.3 to 9/min.
crj, 0.2rtr as the hole diameter of the gas jet nozzle 20
m~0.3mmfi is suitable. When the gas discharged from the gas jet nozzle 20 passes through the injector 22, it simultaneously sucks in surrounding air, and while passing through the mixing pipe 23, the gas and air are mixed and enter the combustion chamber 24. After the mixed gas is divided into a uniform gas flow by the diffusion plate 28 of the combustion chamber 24, it passes through the catalyst 27 having a large number of through holes. At this time, after opening the shutoff valve 17 during the operation of rotating the opening/closing knob 18 described above, the ignition device 40 is activated via the ignition arm 41 attached to the opening/closing knob 18 with a slight time delay. , a spark plug 34 generates a spark. The sparks form flames on the numerous holes on the surface of the catalyst 27.

The catalyst 27 is heated by this flame combustion, and catalytic combustion starts in a short time, and at the same time, the flame combustion disappears. The combustion gas passes under the melting tank 25 and exits from the exhaust gas 42. Temperature control is performed by the above-mentioned temperature adjustment plate 3o, bimetal 29, and temperature adjustment rod 32. After ignition, when the catalyst 27 burns, the base 26 is heated, and the bimetal 29 is heated through the humidity adjustment plate 30 by heat conduction. heated. On the other hand, the bimetal 29 is heated by the radiant heat from the catalyst 27, and the bimetal 29 is bent by both of them.

When the bimetal 29 is heated, the horizontal part of the L-shape bends downward, so the vertical part of the L-shape is displaced in the direction opposite to the combustion chamber 24, and the gas flow rate adjustment valve 19 is moved. It has a pushing effect. The gas flow control valve 19 is the seventh
It has a configuration as shown in the figure, and the displacement of the bimetal 29 causes the spring 43 to be displaced in the compression direction, and the Q1) ring 44 closes the flow path to allow the gas flow. When the temperature of the combustion chamber 24 decreases, the bimetal 29 is displaced in its original direction, and the gas flow resumes.
to control the temperature. When changing the set temperature of the base 26, rotate the degree adjustment knob 33.

In conjunction with this, the temperature adjustment screw portion 32 is displaced in the vertical direction, and therefore the temperature adjustment rod 31 that is attached to the temperature adjustment screw portion 32 by τJ also moves, displacing the temperature adjustment plate 30 in the 1-F direction. . At this time, the bimetal 29 is
It is welded to 0 and is displaced at the same time. As a result, the gap distance between the gas flow rate adjustment valve 19 and the bimetal 29 changes, and the set temperature of the base 26 surface can be changed. When the temperature W' of the melting tank 26 rises and the wax inside melts and becomes liquid, the opening/closing rod 3 can be opened by pressing the opening/closing rod knob 37.
6, and the external hewanox flows out from the wax outflow hole 38.

In the embodiment described above, the temperature adjustment plate 30 and the bimetal 29 may be installed on the downstream side of the gas flow with respect to the catalyst 27 in the combustion chamber 24, that is, on the upper part of the catalyst. This is because moisture generated by combustion comes into contact with the bimetal 29 and causes the bimetal 29 to corrode.

Is it necessary to install it on the upstream side of the gas flow? Furthermore, by locating the bimetal 29 closer to the catalyst 27 than the temperature adjustment plate 30 and on the upper side, the bimetal 29 can easily receive radiant heat from the catalyst 27. If this heat sensitivity is poor, the response of the bimetal 29 is delayed, and when the bimetal 29 is activated to cause the gas to flow out again from the state where the gas flow has been stopped, the catalyst 27 may become too cold and re-combustion may not occur.

Effects of the Invention As is clear from the above examples, the wax applicator of the present invention uses liquefied petroleum gas as fuel, and can be used anywhere, even outdoors, compared to conventional systems that use electricity as a heat source. Along with this, there is also a temperature adjustment board.

By combining bimetal and temperature control rods and considering their arrangement, it is possible to control the temperature of the base surface reliably and with good responsiveness, which was not possible with conventional cordless wax applicators. It is possible to apply wax according to the conditions.
