Description

FIELD OF THE INVENTION [0001] The present invention relates to a combustion apparatus, and more particularly to an air intake device for a combustion apparatus.

BACKGROUND OF THE INVENTION [0002] With the development of science and technology and the improvement of living standards, a combustion apparatus has become a dynamic tool in modern technology. However, the fuel that provides power for the combustion apparatus comes from petroleum. Petroleum is not an inexhaustible natural resource and may be exhausted sometime. Fuel combustion also produces exhaust emission to result in air pollution. The concept of environmental protection is becoming more and more popular. The earth's energy is also increasingly scarce. However, fuel is still the main power fuel for the current combustion apparatus. The formation of petroleum is not a short period of time. Therefore, in order to extend the service life of petroleum and reduce the air pollution caused by the use of fuel, it is the most direct way to increase the combustion efficiency.

[0003] A conventional combustion device includes a combustion chamber. The combustion chamber is connected to an intake pipe. The intake pipe guides the outside air into the combustion chamber for explosion combustion with the fuel so as to generate power. However, explosion combustion of air and fuel is often incomplete. Poor combustion leads to a lot of exhaust gas. Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.

SUMMARY OF THE INVENTION [0004] The primary object of the present invention is to provide an air intake device for a combustion apparatus. Through the negative pressure of the combustion apparatus to guide the outside air into the air intake device, the kinetic energy of the gas molecules in the air is increased through hitting and friction so as to achieve an effect of supporting combustion, and therefore the combustion is more thorough and exhaust emission is reduced.

[0005] In order to achieve the aforesaid object, the air intake device of the present invention comprises a housing and a plurality of partition plates. The housing has a hollow tubular shape. Two ends of the housing are provided with an air inlet and an air outlet respectively along an axial direction of the housing. The partition plates are separated by a plurality of air chambers. The partition plates are arranged within the housing along the axial direction of the housing and perpendicular to an axis of the housing. Each of the partition plates is provided with at least one air hole. The air holes of every adjacent two of the partition plates are arranged in a staggered manner. The air chambers communicate with the air holes of the partition plates to form an air guide channel.

[0006] The air outlet is connected with an air nozzle. The air nozzle is connected to an intake tube. The intake tube is connected to an air return port of a combustion apparatus. When the combustion apparatus is actuated, the air intake device generates a negative pressure to guide the outside air through the air inlet to pass through the filtration medium and enter the housing. When the air passes through the air guide channel, the frequency of gas molecules in the air hitting the partition plates is greatly increased, such that the kinetic energy of the gas molecules in the air is increased through hitting and friction so as to achieve an effect of supporting combustion, and therefore the combustion is more thorough and the exhaust emission is reduced.

[0008] FIG. 2 is an exploded view in accordance with an embodiment of the present invention; and [0009] FIG. 3 is a schematic view in accordance with an embodiment of the present invention, showing the flow of air when in use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0010] Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

[0011] FIG. 1 is a perspective view in accordance with an embodiment of the present invention. FIG. 2 is an exploded view in accordance with an embodiment of the present invention. The present invention discloses an air intake device 100 for a combustion apparatus. The air intake device 100 comprises a housing 10 and a plurality of partition plates 20.

[0012] The housing 10 has a hollow tubular shape. Two ends of the housing 10 are provided with an air inlet 11 and an air outlet 12 respectively along the axial direction of the housing 10. Afilter medium 13 is arranged at a position of the housing 10 corresponding to the air inlet 11. The air outlet 12 is connected with an air nozzle 14.

[0013] The partition plates 20 each have a cone shape and are tilted downwards and outwards from a center thereof. The partition plates 20 are separated by a plurality of air chambers 21. The partition plates 20 are arranged within the housing 10 along the axial direction of the housing 10 and perpendicular to the axis of the housing 10. In addition, each partition plate 20 is provided with a protruding ring 22 extending downwards from an outer periphery thereof. A lower end of the protruding ring 22 has a flange 23 extending outwards. An outer periphery of the flange 23 abuts against an inner wall of the housing 10. Each partition plate 20 is provided with at least one air hole 24. The air holes 24 of every adjacent two of the partition plates 20 are arranged in a staggered manner, such that the air chambers 21 communicate with the air holes 24 to form an air guide channel.

[0014] FIG. 3 is a schematic view in accordance with an embodiment of the present invention when in use. The air intake device 100 is connected to an intake tube 200 through the air nozzle 14, and is further connected to an air return port of a combustion apparatus through the intake tube 200. When the combustion apparatus is actuated, a negative pressure is generated in the housing 10 to guide the outside air through the air inlet 11 to pass through the filter medium 13, thereby blocking the foreign particles and suspended particles in the air, so that the clean air enters the housing 10 through the air inlet 11.

[0015] The adjacent partition plates 20 are stacked on each other with the protruding rings 22 so that the partition plates 20 form a multi-layer structure. The air will collide with the partition plates 20 when the air flows. The outer periphery of the flange 23 abuts against the inner wall of the housing 10 so that the partition plates 20 are tightly disposed in the housing 10 without shaking.

[0016] The partition plates 20 are separated by the air chambers 21. The partition plates 20 are arranged within the housing 10 along the axial direction of the housing 10 and perpendicular to the axis of the housing 10. The air chambers 21 communicate with the air holes 24 to form the air guide channel. The partition plates 20 each have a cone shape and are tilted downwards and outwards from the center thereof. The air guide channel is tortuous. When the negative pressure of the combustion apparatus directs the air to enter the air intake device 100 and pass through the air guide channel, the frequency of gas molecules in the air hitting the partition plates 20 is greatly increased, such that the kinetic energy of the gas molecules in the air is increased through hitting and friction so as to achieve an effect of supporting combustion, and therefore the combustion is more thorough and the exhaust emission is reduced.

[0017] Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
