[0049] The following is a preferred embodiment and is described in more clearly and completely in conjunction with the accompanying drawings for the present utility model.

[0050] This embodiment provides a test device for the discharge performance of an ignition pin, and the specific structure is as Figure 1 、 Figure 2 and Figure 3 shown. The test device for the discharge performance of an ignition pin includes:

[0051] A first platform 1, the first platform 1 is provided with a plurality of receiving portions 11 for receiving the ignition pins 10, the plurality of receiving portions 11 are spaced apart, and the receiving portion 11 has a receiving hole 111 with an adjustable diameter;

[0052] The second platform 2 is provided with a plurality of mounting parts 21 for accommodating the ignition cap 20. The mounting parts 21 correspond to the accommodating parts 11 one by one. The plurality of mounting parts 21 can adjust the height of the ignition cap 20 from the ignition needle 10 as a whole or individually;

[0053] An oscilloscope 3, the oscilloscope 3 is connected to the ignition needle 10 through a wire, and the oscilloscope 3 is arranged on the side of the first platform 1.

[0054] Specifically, both the first platform 1 and the second platform 2 are flat plates. The first platform 1 is located above the second platform 2. A plurality of accommodating parts 11 are arranged at intervals on the first platform 1. The accommodating parts 11 have accommodating holes 111. The accommodating holes 111 are used to accommodate the side part of the ignition needle 10. And the accommodating parts 11 can be used to fix ignition needles 10 of different sizes on the first platform 1 by adjusting the diameter of the accommodating holes 111. It can be understood that the part of the ignition needle 10 for discharging is the end with a smaller size, while the end with a larger size is used to be connected to the oscilloscope 3 through a wire. When the ignition needle 10 discharges to the ignition cap 20, the ignition cap 20 needs to be arranged above the end with a smaller size of the ignition needle 10 to simulate the discharging process between the ignition needle 10 and the ignition cap 20 in a gas stove. By setting the first platform 1 to batch accommodate a plurality of ignition needles 10, and the diameter of the accommodating holes 111 of the accommodating parts 11 can be adjusted to be suitable for ignition needles 10 of different sizes. After a plurality of ignition needles 10 of the same batch are all installed in the accommodating parts 11, centralized testing is carried out through the oscilloscope 3 to ensure that factors such as temperature, humidity, and testing time are the same, and reduce the influence of the environment or other factors on the discharging performance test of the ignition needle 10.

[0055] It should be noted that in this embodiment, the accommodating part 11 is located at the bottom of the first platform 1 to be away from the end with a smaller size of the ignition needle 10, that is, away from the discharging end of the ignition needle 10, so as to reduce the influence on the discharging performance test of the ignition needle 10. And, the mounting part 21 provided on the second platform 2 extends towards the first platform 1. After the ignition cap 20 is installed on the mounting part 21, the height of the ignition cap 20 from the ignition needle 10 can be adjusted through the mounting part 21 to realize setting the ignition cap 20 on the top of the discharging end of the ignition needle 10, and at the same time keep the distances between a plurality of ignition needles 10 and the ignition cap 20 at the same height to batch test the consistency and stability of the discharging performance of the ignition needle 10. In this embodiment, the first platform 1 is taken as an example of a rectangular plate for illustration, but it is not limited thereto. A plurality of accommodating parts 11 are arranged at intervals on the side edges in the length direction of the rectangular plate, and the plurality of accommodating parts 11 are arranged in a "one" shape. The mounting parts 21 correspond to the accommodating parts 11 and are arranged in a "one" shape to realize batch testing of a plurality of ignition needles 10. Of course, in other embodiments, the first platform 1 can also be a circular plate, and the plurality of accommodating parts 11 are arranged in a fan shape around the center of the circle, which can also realize batch testing of the ignition needle 10. Details are not described herein too much.

[0056] In this embodiment, an igniter and a switch connected to the oscilloscope 3 are further provided on the second platform 2. Both the igniter and the switch are structures used to turn on the ignition needle 10 in the prior art. This embodiment does not improve them. The igniter and the switch are sequentially connected to the oscilloscope 3 through wires. This is the prior art and will not be elaborated here.

[0057] In another embodiment, the height of each mounting portion 21 is adjustable and the heights of the ignition caps 20 on each mounting portion 21 may be different. In this way, for the ignition needles 10 of the same batch, on the basis of maintaining a fixed height with the ignition caps 20, the discharge performance of the ignition needles 10 and the ignition caps 20 at different heights is further tested to obtain more discharge parameters of the ignition needles 10 while ensuring that other factors such as the environment are consistent. The above data can be used for the design improvement of the ignition needles 10 to improve the R & D efficiency. It can be understood that the mounting portion 21 can be a telescopic hydraulic rod or a rod driven by a servo motor to adjust the height. This is the prior art and will not be elaborated here.

[0058] As Figure 1 and Figure 3 shown, in this embodiment, a connecting portion 4 is further provided on the second platform 2. The connecting portion 4 is located between the mounting portion 21 and the ignition cap 20. The connecting portion 4 has a plurality of connecting holes 41. The plurality of connecting holes 41 correspond to the plurality of receiving portions 11 one by one, and the heights of the plurality of connecting holes 41 are kept consistent.

[0059] Specifically, the mounting portion 21 is arranged on the second platform 2 and the mounting portion 21 is in a conical structure. The conical structure has a mounting hole to accommodate the connecting portion 4. A plurality of connecting holes 41 are provided on the connecting portion 4 to accommodate a plurality of ignition caps 20. The connecting portion 4 is inserted and connected with the mounting portion 21 so as to replace the connecting portions 4 with different heights, so that the heights of the plurality of ignition caps 20 on the integral structure connecting portion 4 are uniformly adjusted and kept consistent. During the test, the user can move the connecting portion 4 as a whole and drive the adjustment of the heights of the plurality of ignition caps 20 to realize the overall adjustment of the heights of the plurality of ignition caps 20.

[0060] Further, the connecting portion 4 includes a connecting rod 42 and a plurality of sleeves 43. The plurality of sleeves 43 are sequentially arranged on the connecting rod 42. The connecting holes 41 are located on the sleeves 43. The two ends of the connecting rod 42 are correspondingly inserted into the mounting portion 21.

[0061] Specifically, both ends of the connecting rod 42 extend towards the second platform 2 and are inserted into the mounting portion 21, thereby maintaining the height of the overall structure of the connecting portion 4 and the stability of the connecting portion 4. The sleeve 43 is a sleeve structure in the prior art and is used to accommodate the ignition cap 20. One end of the ignition cap 20 is inserted into the sleeve 43 and is positioned by abutting the other end of the ignition cap 20 against the end of the sleeve 43. The extending direction of the connecting rod 42 is the same as the arrangement direction of the plurality of accommodating portions 11. During the test, the user can grasp both ends of the connecting rod 42 or the rod body of the connecting rod 42 to drive the plurality of ignition caps 20 mounted on the connecting portion 4 to move as a whole, and make the heights of the plurality of ignition caps 20 consistent. When the heights of the plurality of ignition caps 20 need to be adjusted, only the height of the connecting rod 42 needs to be adjusted, which simplifies the steps of batch height adjustment of the ignition caps 20 and improves the test efficiency.

[0062] In this embodiment, the first platform 1 is made of an insulating material.

[0063] Specifically, the first platform 1 can be made into a flat plate by plastic material, glass material or ceramic material. The above materials are solid materials used for insulation in the prior art and will not be elaborated here. By setting the first platform 1 as an insulating plate, compared with the first platform 1 made of metal material during the test, the conductivity of the ignition needle 10 during the discharge performance test is reduced, the interference of the peripheral environment of the ignition needle 10 on the test result is avoided, and the test accuracy is improved.

[0064] In this embodiment, a weight reduction hole 12 is provided on the first platform 1, and the accommodating portion 11 is provided near the edge of the first platform 1, and the weight reduction hole 12 is located in the middle area of the first platform 1.

[0065] Specifically, taking the first platform 1 as a rectangular plate for illustration, among them, a plurality of accommodating portions 11 are provided on the edge of the length direction side of the rectangular plate. The main body of the accommodating portion 11 is located at the bottom of the first platform 1, and the accommodating hole 111 is located on the surface of the first platform 1 and penetrates the first platform 1. The weight reduction hole 12 is located in the middle area of the first platform 1 and is spaced from the accommodating hole 111. The depth of the weight reduction hole 12 is less than the thickness of the first platform 1 to reduce the weight of the first platform 1, save insulating materials, and thus reduce the cost of the first platform 1.

[0066] Furthermore, the weight reduction hole 12 penetrates the first platform 1. By making the weight reduction hole 12 penetrate the first platform 1, that is, the depth of the weight reduction hole 12 is consistent with the thickness of the first platform 1, to further reduce the weight and cost of the first platform 1.

[0067] As Figure 2 shown, in this embodiment, a clamping portion 5 is provided in the accommodating hole 111, and the clamping portion 5 is used to move along the radial direction of the ignition needle 10 and abut against the side portion of the ignition needle 10.

[0068] Specifically, one end of the clamping part 5 extends into the accommodation hole 111, and the other end of the clamping part 5 is arranged outside the accommodation hole 111, so as to move along the ignition pin 10 through the clamping part 5, and then abut against the side part of the ignition pin 10, so as to position the ignition pin 10 in the accommodation hole 111. In this embodiment, the clamping part 5 is taken as an example of a bolt for illustration, but it is not limited thereto. A threaded hole is formed in the accommodating part 11 and penetrates into the accommodation hole 111, and the bolt is screwed into the threaded hole to screw and abut against the side wall of the ignition pin 10, so as to position the ignition pin 10 in the accommodation hole 111. By arranging the clamping part 5 to lock the ignition pin 10 in the accommodation hole 111, it is avoided that the height of a certain ignition pin 10 among multiple ignition pins 10 from the ignition cover 20 is different from that of other ignition pins 10 from the ignition cover 20, which affects the test result.

[0069] In other embodiments, the clamping part 5 can also be at least two arc-shaped claws arranged in the accommodation hole 111. The arc-shaped claws can be driven by a servo motor or other driving mechanisms, so as to clamp the side part of the ignition pin 10 and abut against the inner wall of the accommodation hole 111 to realize the positioning of the ignition pin 10 when the ignition pin 10 is placed in the accommodation hole 111.

[0070] It should be noted that the clamping part 5 is made of an insulating material. To reduce the situation that the side part of the ignition pin 10 conducts electricity during the discharge performance test of the ignition pin 10, which interferes with the test result.

[0071] In this embodiment, the ignition pin 10 discharge performance test device further includes an oscilloscope support 31. The oscilloscope 3 is arranged on the oscilloscope support 31, and the oscilloscope support 31 is made of an insulating material.

[0072] Specifically, the oscilloscope support 31 is arranged on the second platform 2. The oscilloscope support 31 includes legs and grooves. There are four legs and they are arranged in pairs. The grooves are used to accommodate the probes of the oscilloscope 3 to ensure the stability of the probes of the oscilloscope 3. By setting the oscilloscope support 31 as an insulating material, it is avoided that the oscilloscope 3 is interfered by the second platform 2 and affects the test result of the discharge performance test of the ignition pin 10.

[0073] In this embodiment, the second platform 2 is made of a conductive metal material. A platform support column 6 is arranged between the first platform 1 and the second platform 2, and the platform support column 6 is made of an insulating material.

[0074] Specifically, the second platform 2 is made of a metal material in the prior art, such as stainless steel. By setting the second platform 2 as a conductive material, the environment where the ignition pin 10 is actually grounded in the bottom box of the gas stove is simulated, so as to improve the accuracy of the test results. In addition, to ensure the accuracy of the discharge performance test of the ignition pin 10, the first platform 1 is arranged above the second platform 2 and supported by a platform pillar 6 made of an insulating material. The insulating material is still made of materials such as glass or ceramic in the prior art to prevent the second platform 2 from conducting electricity to the first platform 1 and affecting the test results. The platform pillar 6 can be connected to the first platform 1 and the second platform 2 by means of bolts. It should be noted that when connecting to the first platform 1, the bolts are still made of insulating materials, while there is no restriction on the connection to the second platform 2.
