Description
Technical field
The utility model relates to lighter parts, specifically a kind of gas flow control device of lighter.
Background technology
The gas flow of tradition lighter controls, a foam being provided with central through hole is set by the bottom of white screw and T-shaped aluminium holder two parts are formed, by being just rotated counterclockwise white screw, to being clipped in bottom white screw and foam volume between the holder of T-shaped aluminium carries out extruding and loosens, thus reach the object that the gas flow of lighter is controlled, it is simple that this device seems structure, but flare control effects is not perfect, and assembly technology is also quite loaded down with trivial details.
Utility model content
The utility model object is the defect existed for overcoming above-mentioned prior art, provides a kind of gas flow control device that reliably can control the lighter of flare.
The defect that the utility model exists to overcome above-mentioned prior art, the technical scheme taked is as follows: the gas flow control device of this lighter is by housing 1, filter mechanism of qi structure 2, filter mechanism of qi structure fixture 3 and foam sealing gasket 4 four part compositions, the profile of housing 1 is column structure, inside is provided with columniform dark cavity, upper end open, base plate center, lower end is provided with through hole, filter mechanism of qi structure fixture 3 is cylindrical, the trickle through hole that columniform center is provided with, filter mechanism of qi structure fixture 3 has been pressed into inside the inner chamber of housing 1 from the upper open end of housing 1 completely, the outer cylinder of filter mechanism of qi structure fixture 3 and the chamber wall of housing 1 inner chamber pass through interference fit, the filter mechanism of qi structure 2 of disc is pressed between the lower end base plate of housing 1 and the bottom surface of filter mechanism of qi structure fixture 3, housing 1 inside forms new scrobicula chamber, a slice foam sealing gasket 4 is set in scrobicula chamber, four Assembly of the parts form an entirety together.With this device together with exhaust valve for lighter with the use of, air outlet valve is responsible for the cut out manipulating combustion gas, gas flow control device controls the height of flare, the effect of foam sealing gasket 4 is that the gas both maintained between gas flow control device and air outlet valve effectively transmits, and prevents again gas side leakage between which.We also can replace foam sealing gasket 4 with ring-shaped rubber pad, but effect can a little almost.We also can coordinate with air outlet valve gas flow control device by connecting, become one, become a part, be convenient to the final assembly of lighter, improve efficiency of installing software.
We are further provided with guiding gutter in bottom, housing bottom surface, are convenient to pour in down a chimney inflation to lighter.
The beneficial effects of the utility model are: because filter mechanism of qi structure 2 is made up of poromerics, so when circulation area is fixing, flare height is constant, so just can improve the quality of flare and promote the efficiency of assembling of lighter, if unclamp foam sealing gasket 4 simultaneously, just can pour in down a chimney from the needle top of air outlet valve to lighter inflation, and then compress foam sealing gasket 4, which offers a saving the expense of equipped intake valve.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model specific embodiment structure sectional view;
Accompanying drawing 2 is the utility model specific embodiment STRUCTURE DECOMPOSITION figure;
Accompanying drawing 3 is the structural representation of the assembly relation of the utility model specific embodiment and air outlet valve.
Detailed description of the invention
As accompanying drawing 1, 2, shown in 3, the utility model is by housing 1, filter mechanism of qi structure 2, filter mechanism of qi structure fixture 3 and foam sealing gasket 4 four part compositions, the profile of housing 1 is column structure, inside is provided with columniform dark cavity 11, upper end open, base plate center, lower end is provided with through hole 12, the sectional area of through hole 12 is valid circulation area of filter mechanism of qi structure 2, its size is directly proportional with flare height, filter mechanism of qi structure fixture 3 is cylindrical, the trickle through hole 31 that columniform center is provided with, filter mechanism of qi structure fixture 3 has been pressed into inside the inner chamber of housing 1 from the upper open end of housing 1 completely, the outer cylinder of filter mechanism of qi structure fixture 3 and the chamber wall of housing 1 inner chamber pass through interference fit, the filter mechanism of qi structure 2 of disc is pressed between the lower end base plate of housing 1 and the bottom surface of filter mechanism of qi structure fixture 3, and sealant is formed on the lower end base plate of annular, the sectional area of central through hole 12 constitutes gas flow and leads to effective area, size decides the height of flare, after filter mechanism of qi structure fixture 3 is pressed into housing 1 cavity, the scrobicula chamber that inner formation is new, a slice foam sealing gasket 4 is set in scrobicula chamber, foam sealing gasket 4 adopts the ventilating structure of perforate, it external diameter be a bit larger tham the internal diameter of cavity 11, one is formed after making four Assembly of the parts.When specifically using, the utility model device is supporting with air outlet valve, air outlet valve 5 is responsible for the cut out of manipulation combustion gas, gas flow control device controls the height of flare, foam sealing gasket 4 is connected to air outlet valve with gas flow control device as bridge, its effect is that the gas both maintained between gas flow control device and air outlet valve effectively transmits, and prevents again gas side leakage between which.In lighter assembling gas replenishment process, before inflation, foam sealing gasket 4 remains releasing orientation, it is inner that combustion gas has entered into gas box by the outer peripheral face-guiding gutter 13 of the side-housing 1 of foam sealing gasket 4, substitute the bad for the good after gas, rotate the external screw thread 51 of air valve 5, the bottom aluminium seat 52 of air outlet valve 5 has entered in cavity 11, compression foam sealing gasket 4, arrive certain degree of depth, very thin (see figure 3) is become after foam sealing gasket 4 is compressed, act on the gasket seal 4 developed into, because foam two is all provided with central through hole, so central shaft to foam more much lower than the density of the foam in the annular location of surrounding, allow that combustion gas is from axially passing through.We can replace foam sealing gasket 4 with rubber blanket, but center must be provided with through hole, and the effect of use there is not foam desirable yet.The convex tendon interference fit that we further can follow the inwall of cavity 11 to arrange by the external diameter of the aluminium seat 52 bottom air outlet valve gas flow control device and air outlet valve, become one, become a part, so just to be more convenient for the final assembly of lighter, improve efficiency of installing software, the mode that the external diameter of the aluminium seat 52 bottom certain air outlet valve connects with the inwall of cavity 11 also has a lot of mode, both be not easy to come off as long as meet, combustion gas aluminium can be allowed again just passable by these two conditions of gap between the outer peripheral face of aluminium seat 52 and the inwall of cavity 11 smoothly.
We further arrange guiding gutter 13 in bottom, housing bottom surface, it is more smooth and easy that Main Function pours in down a chimney gas replenishment process to lighter exactly, and it is inner that fuel gas is that the outer peripheral face-guiding gutter 13 of gap-housing 1 between the outer peripheral face of bottom small through hole-unpressed foam sealing gasket 4-aluminium seat 52 of air-out needle mouth-fluid sealant nail-air outlet valve by air outlet valve and the inwall of cavity 11 has entered into gas box.
