Description

Technical Field

[0001] The utility model relates to a gas stove accessory, in particular to a double - head ignition device for a gas stove. Background Art

[0002] In modern kitchens, gas stoves are widely used because of their convenience. The ignition device is one of the core components of a gas stove, and its main function is to ignite the gas through an electric spark to start the combustion process.

[0003] Traditional ignition devices usually include an ignition needle. When the ignition needle receives a high - voltage current from the ignition controller, it will generate an electric spark near the gas outlet to ignite the gas. However, the existing ignition systems generally have some defects, especially in terms of the reliability of the ignition needle. The damage of the ignition needle often leads to the failure of the entire ignition system, which is particularly common when the ignition needle is worn due to long - term use or the quality is inconsistent during the manufacturing process.

[0004] Once the ignition needle fails, without a backup ignition mechanism, the gas stove will not be able to generate the necessary electric spark, resulting in the inability to complete ignition. This situation not only seriously affects the convenience of cooking operations but also may cause potential safety risks due to the accumulation of unburned gas. Therefore, it is necessary to make further improvements. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the defects of the existing technology and provide a double - head ignition device for a gas stove with a simple structure, convenient use, and capable of effectively improving its ignition reliability and safety.

[0006] The purpose of the utility model is achieved in the following way: A double - head ignition device for a gas stove includes an insulating base. On the top of the insulating base, a first ignition needle and a second ignition needle extend upward side by side. An insulating sleeve is sleeved on the surfaces of the first ignition needle and the second ignition needle. A high - voltage lead is arranged in the insulating base in parallel with the first ignition needle and the second ignition needle, and the other end of the high - voltage lead is connected to a high - voltage pack through a tail wire.

[0007] Further: The insulating base is in a long - waist shape. The first ignition needle and the second ignition needle are arranged on the upper end surface of the insulating base, and the tail wire is connected to the lower end surface of the insulating base.

[0008] Further: The insulating sleeve is in a cylindrical shape and is sleeved on the columnar surfaces of the first ignition needle and the second ignition needle. The tops of the first ignition needle and the second ignition needle protrude above the top of the insulating sleeve.

[0009] Further: A positioning post extends downward from the bottom of the insulating base, and the tail wire passes through the positioning post and is connected to the first ignition needle and the second ignition needle.

[0010] Further: an inwardly concave connecting snap ring is provided on the column surface of the positioning post.

[0011] Further: the insulating base, the insulating sleeve and the positioning post are integrally formed of ceramic material.

[0012] The beneficial effects of the present utility model are as follows: 1. The structure is simple, the production cost is low, and the market competitiveness is improved.

[0013] 2. By adopting the double - headed ignition needle design, even if one of the ignition needles stops working due to damage or other failures, the other ignition needle can still maintain the ignition function. This redundant design significantly enhances the reliability of the ignition system and ensures that the gas stove can still operate normally even when some components fail.

[0014] 3. In the traditional single - ignition - needle system, any failure of the ignition needle may cause failure to ignite, increasing the risk of gas accumulation. While the double - headed ignition device of the present utility model greatly reduces the safety hazards caused by ignition failure by ensuring that at least one ignition needle is always available, thus increasing the safety during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a schematic structural diagram of the present utility model.

[0016] Figure 2 It is a cross - sectional view of the structure of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following further specifically describes the present utility model with reference to the drawings. A double - headed ignition device for a gas stove includes an insulating base 1. The top of the insulating base 1 extends upward in parallel with a first ignition needle 2 and a second ignition needle 3. An insulating sleeve 4 is sleeved on the surfaces of the first ignition needle 2 and the second ignition needle 3. A high - voltage lead 5 is arranged in the insulating base 1 and is connected in parallel with the first ignition needle 2 and the second ignition needle 3. The other end of the high - voltage lead 5 is connected to a high - voltage pack through a tail wire 6.

[0018] In one example, the insulating base 1 is in a long - waist shape. The first ignition needle 2 and the second ignition needle 3 are arranged on the upper end surface of the insulating base 1, and the tail wire 6 is connected to the lower end surface of the insulating base 1.

[0019] In one example, the insulating sleeve 4 is in a cylindrical shape and is sleeved on the column surfaces of the first ignition needle 2 and the second ignition needle 3. The tops of the first ignition needle 2 and the second ignition needle 3 protrude above the top of the insulating sleeve 4.

[0020] In one example, a positioning post 7 further extends downward from the bottom of the insulating base 1, and the tail wire 6 passes through the positioning post 7 and is connected to the first ignition needle 2 and the second ignition needle 3.

[0021] In one example, an inwardly concave connecting snap ring 8 is provided on the column surface of the positioning post 7.

[0022] In one example, the insulating base 1, the insulating sleeve 4 and the positioning post 7 are integrally formed of ceramic material.

[0023] Working principle: The double - head ignition device for gas stoves of the present utility model mainly consists of an insulating base, two ignition needles, an insulating sleeve, a high - voltage lead wire, its connecting tail wire and a high - voltage package. The following elaborates its working principle in detail:

[0024] 1. Basic function of the ignition needle: The ignition needles (the first ignition needle and the second ignition needle) are key components for igniting gas through electric sparks. When the user starts the gas stove, the high - voltage package receives a signal and generates a high - voltage pulsed current. This high - voltage current is transmitted through the tail wire to the high - voltage lead wire and finally reaches the two ignition needles.

[0025] 2. Generation of electric sparks: After the high - voltage current reaches the ignition needle, due to the tiny gap between the tip of the ignition needle and the burner of the gas stove, the current cannot flow directly through the air. Therefore, high - temperature electric sparks are generated between the tip of the ignition needle and the stove. These electric sparks are sufficient to ignite the gas ejected from the burner, thus starting the combustion process.

[0026] 3. Redundant design of double - head ignition: The unique feature of this device lies in its double - head ignition design. In normal use, the two ignition needles can work simultaneously or separately, providing double protection to ensure high efficiency and success rate of ignition. If one of the ignition needles fails (such as due to long - term wear or manufacturing defects), the other ignition needle can still complete the ignition task independently, ensuring the normal operation of the gas stove. This design significantly increases the reliability and safety of the system.

[0027] 4. Further: In this case, the design of the insulating base and the insulating sleeve is to prevent accidental leakage of high - voltage current and ensure safety during use. The insulating base supports the ignition needle and at the same time isolates the high - voltage current from other metal parts of the gas stove to prevent current misdirection. The insulating sleeve is sleeved around the ignition needle, further enhancing the insulation effect, especially protecting the ignition needle from corrosion or damage in high - temperature and humid environments.

[0028] In addition, in this case, ceramic material is selected to make the insulating base and the positioning post not only because of its high heat resistance and corrosion resistance, but also because ceramic has good insulation performance, which can effectively block high - voltage current and prevent current leakage. In addition, the inwardly concave connecting snap ring in the positioning post design provides a stable fixing method for the connection of this ignition device, ensuring its stability after installation.

[0029] Compared with traditional technologies, the dual-head ignition device for the gas stove of the present utility model has advantages in improving the safety, reliability of use and the durability of maintenance of the equipment. This design fully utilizes the comprehensive advantages of dual-head ignition technology and advanced materials, significantly improving the performance and safety of use of household gas stoves, so it can be widely promoted and used.

[0030] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the claims of the present invention.
