1261100 V. Invention description (6) The fifth figure), due to the opening of the body, the metal mesh 119 (please refer to the cylindrical metal mesh 丨9 open, / ^ Meng network 1 1 9 The round metal mesh 1 20 at the end is denser, so it can effectively suppress the Γ/, the resistance and the radial direction of the mesh around the circular metal mesh (2) is 1: body: !, * most of the mixed gas is facing the device 30 When the mixture is ignited and the ignition switch 42 is ignited, the surrounding of the ignition 1 15 is started to enter the flame, and the flame is continuously burned from the combustion chamber when the flame is burned. By the blower 20, the *$ sister's Θ, u rise, for the first time, when the carambola belt 厶Γ, i" over the peach-shaped metal foil 11 3 passage 11 8 metal foil 113埶, 丹片片113 has a good heat exchange rate, taking away the domain, reducing one oxygen;; = a small amount of gas gas is sufficient to obtain a safe and household can raise the temperature of hot air again, free of open flame There are two:::=: / Touch: 14 can avoid the air outlet 14. * The flame that is still burning in the bay piece 113 Among them, the mixture needs to have a good mixing ratio, which can be widely obtained: good, burning rate, and the oxygen content in the combined gas is too low. Z砀δ is again burned to the suction port around 11 5 11 7 The timely replenishment space _: is based on the principle that the constriction 116 of the mixing chamber 112 is tapered, so that the air suction port 11 7 is sucked and mixed with the gas, and enters the combustion chamber 11 5 for stable combustion.

Page 10 1261100 V. INSTRUCTIONS (7) Flow rate; since the metal foil crucible 3 in the heating chamber 111 has a good thermal conductivity 'can be rapidly heated by the combustion chamber 1 15 after ignition, in the heating chamber If the flame in 111 is incompletely burned, it will produce toxic carbon monoxide, which is harmful to the human body. In order to completely burn the flame, the catalyst 丨丨4 can achieve this purpose. 'The catalyst 11 4 can be chemically oxidized with the gas in the combustion. The reaction converts the burned gas into non-toxic carbon dioxide to form a safe gas discharge, and the catalyst 11 4 can prevent the occurrence of open flame, effectively preventing the flame from leaking out of the gas outlet 14 . In addition to the front of the 11 can make the delivery more dissipative; the device 2 3 is closed to maintain a high temperature and low heating rate, so, after that, it is not easy to send the 60 system, the design of the blower 20 will The motor 21 is located on one side of the pipe portion, so that the blade 22 is located on one side of the rear of the pipe portion 11, so that the wind output from the fan 20 is relatively gentle, and the gas emitted from the nozzle 5 is easily ignited by the ignition device 30. Without being subjected to a strong wind blowing blower 20, a temperature sensor 2 is connected to the temperature sensing device 2, and the temperature sensing device is mounted on the tube portion U near the heating chamber 111. When the power switch 41, the nozzle 5^0 is stopped. The air jet, the heating chamber 丨丨} ends the combustion process and remains hot. At this time, the temperature sensor 2 3 senses that the heating chamber is working and the blower 20 is energized, so that the blower 2 〇 operates to maintain the air supply to lower the temperature of the chamber 111. Since the metal foil 113 has a good heat conduction, the cold air can be quickly absorbed to cool down, and the heating chamber is cooled, ", and the temperature sensor 2 senses the heating chamber 丨丨i to reach a certain cold two to send the blower 20 Power outage, weeping a design makes * invention more There is also a risk of burns. π π and with reference to the sixth figure, which is another preferred embodiment of the present invention, has a ring shape, and also has a plurality of nozzle holes 6 丨, the ring shape = j

1261100 V. DESCRIPTION OF THE INVENTION (8) The gas body sprayed from the periphery of the head 60 and the middle 6 1; the gas sprayed from the nozzle hole 71 in the seventh figure, the gas of the present invention, Not only can it be light and short, it reduces the invention. As described above, the present invention has a plurality of nozzle holes, a gas mixed with a large amount of oxygen, and can be sufficiently filled when burned, which is a very special. 2. The invention can be designed into different air. Fully mixed 3. The design of the present invention does not occupy a space that is lighter and shorter, and the present invention has been used by those skilled in the art to be effective in the state in which the nozzle of the present invention is placed in the state of the nozzle. The design of the sprinkler head is provided with a full-filled van. In the detailed example of the example, the vacant part can be effectively mixed with the air body, and the production of the ejector nozzle 70 is an effective mixing of the surrounding gas of the intersection and the nozzle 70, with a porous nozzle 5 〇 Knowing the warmth of the wind, it can take up space and be easy to carry. It can be concluded that the gas hot air works through the average sub-area and uniformly forms a good complete combustion, with a safe Covas hot air shape, and burns gas. Gas heat can still be supplied to facilitate the best implementation of the airflow from the best implementation, but can be mixed with the spray hole south of the shape of the combustion gas, which has a supply of air, the fish can produce a high mixing ratio The combustion to supply the high mixing ratio makes the design of the body 10 more, so it is one of the most advanced advantages: the improved one, in which the nozzle hole on the nozzle is simultaneously sprayed into the mixing chamber and the air. The combustion gas, which is improved in the production of carbon monoxide, wherein the nozzle has a plurality of nozzle holes to obtain and improve, wherein the nozzle gas can be described by the body design pattern. Familiar with more changes without having to deviate from this
