Description

Gas container removal apparatus for portable gas burner {Gas container jointing apparatus for portable gas burner}

The present invention relates to a detachable device for a gas container of a portable gas burner, and more specifically, to perform the attachment / detachment of a gas container and the point / fire extinguishing and fire control at the same time only with a minimum rotation operation of a control knob for controlling spark ignition and fire power. At the same time, the present invention relates to a gas container detachable device for a portable gas burner having improved structure to reduce the frictional wear between operations in the operation relationship between components for attaching / detaching the gas container.

In general, portable gas burner, a cooking utensil that is widely used regardless of place such as home, outdoor or restaurant, is usually equipped with a gas container fueled with butane, and then closes the gas container to the device by downward operation of the lever. The two-stage ignition method was adopted by turning the control knobs for spark ignition and fire control.

Recently, however, problems and inconveniences inherent in the conventional portable gas burner of the two-stage operation method have been raised, and the attachment / detaching of the gas container, the spark ignition of the burner, and the control of the thermal power are all performed at the same time by only rotating the adjustment knob. There is an example (Registration Utility Model No. 20-0306041) designed to improve the portable gas burner.

Looking at the description of the literature through Figures 1, and 2a, 2b,

In FIG. 1, the portable gas burner (A) has a burner portion (A-1) that occupies an area of approximately 3/4, and a predetermined space portion is provided to mount the gas container (B) on one side thereof, and a container protective cover ( A gas container mounting portion A-2 is provided to protect the gas container B by A-3).

Referring to the gas container mounting portion (A-2) as shown in Figure 2a and 2b in more detail, the control knob 100 protruding eccentrically to the operating rib 101 on one side of the rear surface of the portable gas burner Rotational operation is possible, and a horizontal base plate 102 and a vertical base plate 103 are fixedly positioned at an inner bottom of the gas container mounting portion A-2, and at one side of the horizontal base plate 102. The gas container holder 110 which is slidably coupled to the front and rear movements by the extension piece 111 and is supported by the return spring 112 and seats the gas container at the bottom thereof, while the gas container The cradle 110 is pivotally coupled on the horizontal base plate 102, and one end thereof is coupled by a cam groove 113 and a cam 114 having a predetermined shape by the operation of the operating rib 101 of the adjustment knob 100. If you rotate a certain section A cradle traction link 115 is provided to direct the gas vessel holder 110 to the control knob 100.

On the other hand, the vertical base plate 103 is slidingly coupled by the spring 121 so as to be able to swing in the vertical direction, the locking jaw so as to cover the operating range of the operating rib 101 formed on the adjustment knob 100 on the top And a release link 120 formed of a latch 123 selectively engaged with the position fixing groove 111a of the extension piece 111 to fix the position of the gas container holder 110 towed below. ) And so on.

Accordingly, when the control knob 100 is rotated in the ignition direction when the gas burner is ignited, the holder traction link 115 is first pushed laterally by the operation rib 101 as shown in FIG. 2A, and the traction link 115 ) Rotates about the pivot. At this time, the cam 114 is slid by the change of the position of the cam groove 113, and the cradle traction link 115 including the extension piece 111 has the horizontal base plate 102. Guided on, it moves straight ahead. Meanwhile, at the completion of the towing, the latch 123 of the release link 120 is inserted into the position fixing groove 105 to maintain the towed state. Continuously, the operating rib 101 of the adjustment knob 100 is simply ignited by operating the spark plug 130 out of the range of the cradle traction link 115.

On the contrary, in order to extinguish the control knob 100, the operating rib 101 pushes the locking jaw 122 of the locking and releasing link 120 upward, and at the same time, the latch 123 of the link 120. ) Is released from the position fixing groove 105, and at the same time from the gas flow controller 140 in which the gas vessel holder 110 is returned to its original position, that is, the gas vessel is fixed to the horizontal base plate 102 by the return spring 111. To get away.

However, the gas container detachment device of the conventional portable gas burner can provide the convenience of operation because the operation state of the gas container can be attached / detached and the ignition and the fire extinguishing is performed only once at a time. In addition, the coupling relationship between the components is complicated, the frictional coupling and the noise is severe in the sliding coupling portion, and the conventional design described above converts the rotational motion into a linear motion as the cam moves along the cam curve. Because of the way to pull the container, there was a problem that not only the friction wear but also the operating load is not easy to operate.

In addition, the conventional design, as mentioned above, because the gam is sliding on the cam curve, if a continuous fatigue wear occurs in the sliding part, the deformation occurs on the cam or cam curve surface, the operation problem that does not properly install the gas container And problems such as leaking gas in the container.

In addition, because the cradle traction link for towing the gas container cradle is a cam type that moves along the cam curve, there is a problem that the adjustment knob must be rotated more than necessary to tow to the desired straight distance of the gas container cradle. There was also a problem that the operation ribs that interfere with the cradle traction link by the control knob operated above is worn by the phenomenon that the end of the cradle traction link is scratched.

Therefore, the present invention has been devised to solve the above problems, and its purpose is to perform the attachment / detachment of the gas container and the point / extinguishing and fire control at the same time only with the minimum rotation operation of the control knob for spark ignition and fire control. In addition, the present invention provides a gas container detachable device for a portable gas burner having an improved structure to reduce the frictional wear between the operation in the operation relationship between the components for attaching and detaching the gas container to perform the operation more smoothly.

The configuration of the present invention is the operation rib 11 formed eccentrically protruding on one side of the rear side of the adjustment knob 10 is attached / detached and the point / In the gas container detachable device of the portable gas burner to perform a fire extinguishing and fire control at the same time,

3 to 5, the control knob 10 for ignition and flame control is mounted to the lower portion of the gas container mounting portion 1, and also to the rear side of the control knob 10 An operating rib track groove 22 having a circular locus formed therein is formed to enable rotational movement of the protruding actuated rib 12, and an L-shaped base plate 20 having a gas flow controller 70 fixed thereto is provided. . In addition, the spark plug 60 is disposed on one side of the base plate 20 so as to face the linear movement direction of the slider 50 to be described later.

In addition, the rear of the base plate 20 is slidingly coupled with the portable gas burner main body to allow a predetermined distance linear movement by the sliding guide 32, the return spring 34 having a predetermined elastic force is installed in the bottom, gas A gas container holder 30 is provided to seat the container.

In addition, the rear side of the gas vessel holder 30 is provided with a leaf spring 38 to reduce the frictional load caused by the gas vessel mounted in the over-load (over-load) of the gas vessel holder 30 towed.

Meanwhile, a first eccentric rib is pivotally coupled to the bottom of the base plate 20 so as to be rotatable from a rotation center point, and eccentrically pivotally coupled to the traction link 36 formed from the gas container holder 30. The rotating piece 40 which has 42 is comprised. On the other hand, the rotary piece 40 is formed with a second eccentric rib 43 of the same shape as the rib at a position orthogonal to the first eccentric rib 42, the second eccentric rib 43 will be described later This will be described again in the description of the slider 50.

On the other hand, it is located on the base plate 20 so as to be close to the operating rib 12 of the adjustment knob 10 and at the same time facing the spark plug 60 installed on one side of the base plate 20, the base The actuating pin 46 is formed in the clearance hole 44 of the second eccentric rib 43 of the rotating piece 40, which passes through the rotating piece operating hole 24 of the plate 20 and is orthogonal to the pivot point of the traction link 36. ) Is coupled to one end, the interlocking movement of the operation ribs 12 of the control knob 10 (ignition) is interfering with the linear movement at the same time the rotation piece 40 to interlock the gas vessel holder 30 to the gas flow controller A slider 50 having a locking rib 52 is provided to be pulled toward the 70. The locking rib 52 is provided with an ignition hole 52a to contact the ignition end of the ignition plug 60 facing the operation rib 12 during the ignition operation.

The inner diameter of the clearance hole 44 of the second eccentric rib 43 of the rotating piece 40 is formed larger than the diameter of the operating pin 46, the reason for the operation according to the rotational movement of the rotating piece 40 The pin 46 allows linear movement on the rotating piece operating slot 24 in a certain section, and unlike the conventional cam method, improves the traction responsiveness of the gas container holder and adjusts the knob as shown in FIG. Friction wear occurs as the operating rib 12 of the adjusting knob 10 is out of the slider 50 by inducing the rotational track α of the operating rib 12 of the present invention to be significantly reduced as compared with the conventional art. This is to solve the problem.

In addition, the slider 50 and the base plate are slidably coupled to the other side of the slider 50 by the elastic spring 55 when the gas container holder 30 reaches the maximum traction point when ignition. A rocker for determining a moving position of the slider 50 by forming a through hole 57 and a lock hole 58 in the slider 50 and the base plate 20 so that they can be engaged while being simultaneously passed through the 20. 53 and the locker 53, the release piece 54 for interfering with the operating ribs 12 at the time of fire extinguishing to release the locker 53 in the engaged state to return to the original position is integrally formed.

Referring to the operating state of the subject innovation configured as described above are as follows.

As shown in FIG. 5A, when the control knob 10 is rotated in the same direction as the arrow to operate in the fired state of the gas burner as shown in FIG. 5B, the operating rib 12 of the control knob 10 draws a rotational trajectory. At this time, the operating rib 12 is encountered at the inner end of the locking rib 52 of the slider 50 lying on the range of the trajectory, the user is a return spring which is carried in the gas container holder 30 When the operating rib 12 is moved by a force that overcomes the elastic force of the 34, the slider 50 moves linearly toward the spark plug 60, and at the same time, the operation pin 46 interlocked with the rotary piece operating hole 24 Move along.

As the operation pin 46 moves linearly, the rotating piece 40 is rotated by a clearance hole 44 of the second eccentric rib 43, and is connected to the first eccentric rib 42. The gas container holder 30 is linearly moved by the sliding guide 32 by the traction link 36.

Thereafter, when the slider 50 reaches the maximum linear movement point by the operating rib 12, the through hole 57 formed on the slider 50 and the lock hole 58 formed on the base plate 12 face each other. At the same time, the elastic force of the elastic spring 55 is actuated so that the rocker 53 slidingly coupled to the other side of the slider 50 is inserted into the through hole 57 and the lock hole 58 in turn. Not shown) and the gas flow controller 70 to maintain a close contact state.

At the same time, if the adjustment knob 10 is moved further in the same rotation direction in the above state, the operation rib 12 protrudes through the ignition hole 52a of the locking rib 52 without departing from the range of the slider 50. Touching the spark plug 60 is to ignite the burner.

If you want to extinguish from the above, move the control knob 10 in the direction of extinguishing the fire (opposite direction of the arrow), the flame is extinguished while the actuating rib 12 has a release piece 54 integral with the rocker 53. At this time, the locker 53 is released from the lock hole 58 on the side of the base plate 20 and the locking state is released. At the same time, the gas container holder 30 is returned by the return spring 32 as shown in FIG. 4A. It will return to its original position.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

Applying the configuration of the present invention as described above, the operation state of the gas container attachment / desorption and ignition and extinguishing is not only made continuously at a time, but also the components and their organic coupling relationship is simple, in particular, the present invention is a gas Since the traction operation configuration of the container holder is a rotational method rather than a cam and cam curve, the working load is much reduced and frictional wear is significantly reduced, so that even if fatigue wear is continuously applied to the parts, wear deformation between the configurations is achieved. It is minimized to solve the problem that the gas leaks in the gas container during operation, and also compared to the conventional cam method, the traction responsiveness of the gas container cradle is good, because the operation range of the adjustment knob can be minimized, the operability is improved.

In addition, since the leaf spring is additionally configured at the rear of the gas container holder, there is an effect of reducing the frictional load caused by the gas container when the holder is overloaded.

In addition, since most of the operating relationship (rotating piece, etc.) for the traction is installed in the base plate bottom, there is an aesthetically superior effect compared to the prior art.
