Abstract

PURPOSE:To permit to maximize the supplying amount of gas quickly by a simple structure by a method wherein the title cock device is provided with a cock body, accommodating a pivotable type needle for regulating the supplying amount of gas, and a cock arm, moving a fire regulating lever from the position of weak to the position of strong while operating in conjunction with a fire extinguishing button. CONSTITUTION:When a fire regulating lever 5 is operated to regulate the supplying amount of gas to the weakest position, a needle 9 is abutted against a cock body 8 and the gas flows through only a small hole 13 in the needle 9. Next, when a fire extinguishing button 2 is pushed to stop the supply of the gas, a cock arm 4 is operated in conjunction with a pushing section 14 to pivot the fire regulating lever 5 to the position of strong. According to this method, the needle 9 is pivoted and a gap 10 is formed between the cock body 8 and the tip end of the needle 9 and the needle is stopped at a position to maximize the supplying amount of gas. Accordingly, burning condition may be brought quickly and smoothly upon igniting a gas instrument.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a gas appliance plug device for supplying gas to a gas burner such as a gas staple.

Conventional technology 1: In a gas appliance plug device for home use, an operating shaft with a cup housed in the cock body is moved in the axial direction by an operating lever to open and close the gas passage. Many coverings are used.

An example of the conventional gas appliance plug device described above will be described below with reference to the drawings.

FIG. 5 shows a cross section of a conventional gas appliance plug device. In Fig. 5, 21 is an operating knob, 22 is a guide plate, 23 is an operating lever, 24 is a main valve which also serves as a bypass valve (hereinafter referred to as the main valve), 25 is an intermediate valve, and 26 is an opening valve. It is. In such a configuration, the operation knob 21
When pressed, the guide plate 22 is pressed, the main valve 24 opens, and gas flows. Thereafter, the amount of gas is adjusted to an arbitrary value using the operating lever 23.

Problems to be Solved by the Invention However, the conventional configuration as described above has a drawback in that the main valve 24, the middle valve 25, and the weak valve 26 are required to adjust the firepower. Also, if you try to ignite the fire after the fire is extinguished with a little less than 0 gas, a backfire phenomenon will occur if the gas amount remains low. Therefore, the main valve 24 requires the formation of a bypass passage in order to maximize the amount of gas supplied at the time of ignition, which poses a problem in that it not only becomes structurally complicated but also becomes a cause of failure.

The present invention solves these problems, and provides a gas appliance plug device that can reduce assembly time and the number of parts by simplifying the structure and ensure quality. It is.

Means for Solving the Problems In order to solve the above-mentioned problems, the gas appliance plug device of the present invention includes a lock body with a built-in rotary needle for adjusting the amount of gas, and a screw body for rotating the needle. The cock arm is provided with a fire power adjustment lever and a cock arm that is linked to a fire extinguishing button and moves the fire power adjusting lever to a strong position by operating the fire extinguishing button when the fire power adjusting lever is in a low position. be.

Effect of the present invention With the above-described configuration, when the fire extinguishing button is pressed, the cock arm moves the fire power adjustment lever to the strong position in conjunction with this, thereby making it possible to maximize the gas spacing.

Example The following is a gas example of an example of the present invention. ! The shell plug device will be explained with reference to the drawings.

FIG. 3 is a diagram showing the flow of gas, and the following explanation will be given based on this FIG. 3. FIG. 3 (A>) shows a state in which the gas is stopped; at this time, there is a gap 10 between the tip of the needle 9 and the cock body 8. That is,
It is in a stopped state with the maximum amount of gas flowing. FIG. 3(B) is a state diagram when the ignition button 1 is pressed, and gas is flowing into the main gas passage 11 and the pilot gas passage 12. Figure 3 (C) shows when the ignition button 1 is released after ignition, and the main gas passage 1
Gas is flowing only in 1.

FIG. 4(B) shows a diagram when the user arbitrarily operates the heating power adjustment lever 5 to set the temperature to the weakest gas level. At this time, the needle 9 is in pressure contact with the cock body 8, and gas only flows through the small hole 13 inside the needle 9. Next, when the fire extinguishing button 2 shown in FIG. 1 is pressed in an attempt to stop the gas, the cock arm 4 interlocks with the pressed portion 14 of the fire power adjustment lever 5 and rotates the fire power adjustment lever 5 to the strong position. As a result, the state shown in FIG. 4(A) (same state as in FIG. 3(A)) is restored.

In addition, as shown in FIGS. 1 and 2, the fire power adjustment lever 5
The cock arm 4 is configured to be rotatable around a fixing pin 7 and rotates around a bottle 13 in conjunction with the extinguishing button 1.
The firepower adjustment lever 5 is configured to rotate when the user presses the pressed portion 14 . , 3 is a frame body, and 6 is a fixing metal fitting.

Effects of the Invention As described above, the present invention works in conjunction with the suppression of the fire extinguishing button, the tsuku arm pushes the firepower adjustment lever, the needle rotates, and the fire is cocked)! ; Since it forms a gap between f and the tip of the needle and stops at the position where the gas gap is maximized, it is possible to provide a product with a small number of parts and with fewer failures in terms of quality. 8゛, Practical 1 It is extremely right-handed.
