Technical Field

[0001] The present application relates to the field of igniter technology, and in particular to an ignition needle assembly and a gas device. Background Art

[0002] The ignition needle can use the electromagnetic induction principle or piezoelectric discharge principle to generate an arc or spark, which then ignites the gas to complete ignition. However, the ionization arc range generated by the ignition needle in the prior art is small, so the probability of ignition is not very high.

[0003] In summary, the probability of the ignition needle in the prior art igniting the flammable gas is not particularly high, and the convenience of igniting the flammable gas is poor, which in turn leads to a poor user experience, so there is room for further improvement. Utility Model Content

[0004] In view of this, the present application provides an ignition needle assembly and a gas device, which can enable the user to have a higher probability of igniting flammable gas when igniting flammable gas, thereby improving the convenience of igniting flammable gas and improving the user's experience of using the ignition needle.

[0005] In order to enhance the convenience of igniting flammable gases and improve the user's experience in using an ignition needle, the present application provides an ignition needle assembly.

[0006] The present application provides an ignition needle assembly adopting the following technical solution:

[0007] An ignition needle assembly comprises an ignition needle and an ignition cap, wherein the ignition needle is electrically connected to the ignition cap; a through hole is formed on the ignition cap, and the ignition cap is sleeved on the ignition needle through the through hole.

[0008] By adopting the above technical solution, the ignition needle is electrically connected to the ignition cap, so that the discharge area of ​​the ignition needle assembly is not only the needle end of the ignition needle, but also includes the ignition cap, thereby expanding the overall discharge area of ​​the ignition needle assembly, thereby increasing the probability of the ignition needle assembly igniting flammable gas, improving the convenience of igniting flammable gas, and improving the user's experience of using the ignition needle. The ignition needle and the ignition cap are socketed so that the ignition needle is at least partially located in the ignition cap, and because the ignition needle and the ignition cap are electrically connected, the discharge areas of the ignition needle and the ignition cap are consistent, which facilitates the ignition of the accumulated flammable gas by the discharge of the ignition needle or the ignition cap.

[0009] Preferably, the ignition cap is in the shape of a disk, a bowl, or a trumpet.

[0010] By adopting the above technical solution, the disc-shaped, bowl-shaped, and trumpet-shaped ignition caps have excellent discharge effects, and the bowl-shaped and trumpet-shaped ignition caps also have excellent effects of gathering flammable gas and accommodating the rebound of flammable gas airflow, making it easier for the gathered flammable gas to be ignited by the ignition needle or the ignition cap discharge.

[0011] Preferably, the ignition cap has a cavity, and the free end of the ignition needle is at least partially located outside the cavity of the ignition cap.

[0012] By adopting the above technical solution, the ignition cap can gather part of the flammable gas, which makes it easier for the ignition needle inside the ignition cap and the ignition cap itself to discharge and ignite the flammable gas, which is beneficial to improving the efficiency of the ignition needle assembly in igniting the flammable gas and improving the user's experience of using the ignition needle. The ignition needle is at least partially located outside the cavity of the ignition cap, so that the discharge area of ​​the ignition needle and the ignition cap is set to an arc shape, so that the range of discharge and ignition of the ignition needle and the ignition cap is not only wide due to the spatial range of the discharge cap, but also has a certain depth, so that the ignition needle assembly has richer ignition capabilities when dealing with burners of various shapes.

[0013] Preferably, the cavity formed by the ignition cap is conical.

[0014] By adopting the above technical solution, by setting the cavity of the ignition cap into a cone shape, the flammable gas from the burner is discharged through the burner and mixed with oxygen in the air. After reaching the ignition cap of the ignition needle, the mixed flammable gas will diffuse in a cone shape inside the ignition cap, thereby forming an airflow rebound, which makes it easier for the accumulated flammable gas to be ignited by the ignition needle or the ignition cap by discharge, which is beneficial to improving the efficiency of the ignition needle assembly in igniting the flammable gas and improving the user experience of using the ignition needle.

[0015] Preferably, the cavity includes a conical portion and a cylindrical portion, the conical portion is communicated with the cylindrical portion, and the cylindrical portion is arranged near the free end of the ignition needle.

[0016] By adopting the above technical solution, the ignition cap can gather more flammable gas through the cylindrical part, and the flammable gas can be diffused in a cone shape inside the ignition cap through the conical part, thereby forming an airflow rebound, which makes it easier for the flammable gas to be ignited by the ignition needle or the ignition cap through discharge, which is beneficial to improving the efficiency of the ignition needle assembly in igniting the flammable gas and improving the user experience of using the ignition needle.

[0017] Preferably, the free end of the ignition needle is located at the central axial position of the ignition cap.

[0018] By adopting the above technical solution, the ignition needle can easily ignite the flammable gas discharged from the burner head and also ignite the flammable gas in the ignition cap. Moreover, since the ignition cap also has the ability to ignite flammable gas, the free end of the ignition needle located in the middle axial position of the ignition cap can form an ignition area with the ignition cap that can easily ignite the flammable gas.

[0019] Preferably, the ignition needle includes a connecting portion and a needle tip portion, the connecting portion and the needle tip portion are integrally formed, the ignition cap is sleeved with the connecting portion through a through hole, and the ignition cap is electrically connected to the connecting portion, and the needle tip portion is located at any position in the central axial direction of the ignition cap.

[0020] By adopting the above technical solution, when the ignition needle discharges and ignites the flammable gas, the needle tip of the ignition needle responsible for discharge is located at the center of the ignition cap, which is convenient for igniting the flammable gas discharged from the burner and the flammable gas in the ignition cap.

[0021] Preferably, a piezoelectric igniter is further included, and the piezoelectric igniter is connected to the ignition needle.

[0022] By adopting the above technical solution, when the user presses the piezoelectric lighter, the piezoelectric lighter generates a higher voltage through piezoelectric discharge, thereby causing the ignition needle and ignition cap connected to the piezoelectric lighter to produce discharge, thereby igniting the flammable gas.

[0023] In order to enhance the convenience of igniting flammable gas and improve the user experience of using a gas device, the present application provides a gas device.

[0024] The gas device provided in this application adopts the following technical solution:

[0025] A gas device comprises a gas body and the above-mentioned ignition needle assembly, wherein the ignition needle assembly is connected to the gas body.

[0026] By adopting the above technical solution, the ignition needle assembly can not only be discharged and ignited through the ignition needle, but also be discharged and ignited through the ignition cap, so that the ignition needle assembly has a higher ignition efficiency, and thus the ignition success rate of the gas device is also higher, so that the user's ignition experience is higher, and thus the user's experience of using the gas device is better.

[0027] Preferably, the gas body includes a gas shell, a burner head and a gas tank, the burner head is connected to the gas shell, the gas tank is connected to the burner head, and the ignition needle assembly is connected to the gas shell, so that the ignition position of the ignition needle assembly is aligned with the burner head.

[0028] By adopting the above technical solution, the gas tank guides the flammable gas out through the burner head. After being discharged from the burner head and mixed with oxygen in the air, the flammable gas is discharged and ignited by the ignition needle or ignition cap. The ignition cap can expand the discharge area of ​​the ignition needle, which is beneficial to improve the efficiency of the ignition needle assembly in igniting the gas and improve the user's experience in using the ignition needle.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. The ignition needle is electrically connected to the ignition cap, so that the discharge area of ​​the ignition needle assembly is not only the needle end of the ignition needle, but also includes the ignition cap, thereby expanding the discharge area of ​​the entire ignition needle assembly, thereby increasing the probability of the ignition needle assembly igniting flammable gas, improving the convenience of igniting flammable gas, and improving the user experience of using the ignition needle. The ignition needle and the ignition cap are socketed, so that the ignition needle is at least partially located inside the ignition cap. Since the ignition needle and the ignition cap are electrically connected, the discharge areas of the ignition needle and the ignition cap are consistent, making it easier for the accumulated flammable gas to be ignited by the discharge of the ignition needle or the ignition cap;

[0031] 2. Disk-shaped, bowl-shaped, and trumpet-shaped ignition caps have excellent discharge effects. Bowl-shaped and trumpet-shaped ignition caps also have excellent effects of gathering flammable gas and accommodating the rebound of flammable gas airflow, making it easier for the gathered flammable gas to be ignited by the ignition needle or ignition cap discharge.

The connecting portion 6 passes through the through hole of the ignition cap 2, so that the ignition cap 2 is sleeved on the connecting portion 6, and the connecting portion 6 is electrically connected to the ignition cap 2, and the other end is integrally formed with the needle tip 7. The end of the needle tip 7 that is not involved in the connection is the free end of the ignition needle 1, and the free end of the ignition needle 1 can discharge, thereby playing a role in ignition. Due to the effect of flammable gas, the ignition cap 2 also has a discharge function due to the electrical connection between the ignition needle 1 and the ignition cap 2, which enables the ignition cap 2 to expand the discharge area of ​​the ignition needle 1, thereby increasing the probability of the ignition needle assembly 9 igniting the flammable gas, improving the convenience of igniting the flammable gas, and improving the user's experience of using the ignition needle 1. The free end of the ignition needle 1 is located outside the cavity 3 of the ignition cap 2.
