Specifically, referring to fig. 4 and 5, in a first implementation manner, the support member 141 may include a first support member 1411, a second support member 1412 and a third support member 1413, wherein the first support member 1411 is disposed around a sidewall of the side of the light shield 14 close to the light shield 13, the third support member 1413 is disposed around a sidewall of the side of the light shield 14 far from the light shield 13, and the second support member 1412 is located between the first support member 1411 and the second support member 1412. It should be noted that the number of the supporting members 141 is not further limited in this embodiment.

Specifically, during assembly, the nixie tubes 122 with smaller specifications can abut against the first support 1411, and the nixie tubes 122 with larger specifications can abut against the third support 1413, so that the nixie tubes 122 with different specifications can be assembled.

Specifically, the cross section of the supporting member 141 is rectangular along a direction from one side wall of the light shield 14 to the opposite side wall of the light shield 14, wherein in the embodiment, referring to fig. 13, the length of the first supporting member 1411 may be in a range of 10-20mm, and the width of the first supporting member 1411 may be in a range of 5-12 mm; the length of the second support 1412 ranges from 12-30mm, the width of the second support 1412 ranges from 7-16 mm; the length of the third support 1413 ranges from 14-60mm and the width of the third support 1413 ranges from 10-25 mm.

Specifically, the length of the first support 1411 may range from L1, wherein L1 may be 10mm, L1 may be 15mm, L1 may be 20mm, and the width of the first support 1411 may range from D1, wherein D1 may be 5mm, D1 may be 10mm, and D1 may be 12 mm.

The length of the second support 1412 may range from L2, wherein L2 may be 12mm, L2 may be 20mm, L2 may be 30mm, and the width of the second support 1412 may range from D2, wherein D2 may be 7mm, D2 may be 10mm, and D2 may be 16 mm.

The length range and the width range of the first support 1411, the second support 1412 and the third support 1413 are limited, so that the nixie tubes 122 with different specifications can be adapted during the assembly process; on the other hand, the nixie tube 122 can be ensured to abut against the support 141, so that the problem that the nixie tube 122 falls off from the support 141 can be avoided.

Secondly, by limiting the length range and the width range, that is, the supporting member 141 has a certain thickness, it is beneficial to improve the supporting force of the supporting member 141, so as to support and limit the nixie tube 122 to the maximum extent, and avoid the problem that the nixie tube 122 falls off from the supporting member 141.

Specifically, in a direction in which the extending direction of the supporting members 141 is parallel to the circuit board 12, the length of the first supporting member 1411 is smaller than that of the second supporting member 1412, the length of the second supporting member 1412 is smaller than that of the third supporting member 1413, and the length difference range between the adjacent supporting members 141 is greater than 1 mm;

in a direction perpendicular to the circuit board 12 in the extending direction of the support members 141, the width of the first support member 1411 is smaller than the width of the second support member 1412, the width of the second support member 1412 is smaller than the width of the third support member 1413, and the width difference range between the adjacent support members 141 is greater than 1 mm.

By defining the length difference and the width difference between the adjacent supporters 141, on one hand, it is ensured that the nixie tube 122 can have enough space to fit on the corresponding supporter 141; on the other hand, the problem that the nixie tubes 122 interfere with each other during assembly can be prevented.

In a possible implementation manner, a plurality of abutting steps can be arranged on the nixie tube 122, each abutting step is provided with a step surface, wherein the number of abutting steps is not further limited, and the nixie tube 122 is provided with a plurality of step surfaces related to which support 141 the nixie tube 122 abuts.

Specifically, when the nixie tube 122 is provided with a step surface, the nixie tube 122 may correspondingly abut against any one of the first support 1411, the second support 1412 and the third support 1413; when the nixie tube 122 is provided with two step surfaces, the nixie tube 122 can correspondingly abut against the first support 1411 and the second support 1412, or the second support 1412 and the third support 1413; when the nixie tube 122 is provided with three step surfaces, the nixie tube 122 can be correspondingly abutted against the first support 1411, the second support 1412 and the third support 1413 at the same time, so that the universality of the nixie tube 122 can be further improved and the user experience can be improved during assembly.

In one possible implementation, the light shield 14 is provided with a light-conducting coating on its inner wall; one surface of the light shield 14 close to the display part 20 is of an opening structure; alternatively, the surface of the light shield 14 adjacent to the display unit 20 is a light-transmitting surface.

When the end face of the light shield 14 close to the display portion 20 is an opening structure, the nixie tube 122 can penetrate out of the opening under the action of the supporting member 141, so that the light emitted by the light emitting end of the nixie tube 122 is emitted to the display portion 20 through the light shield 14 and is displayed outside the housing 10, and therefore a user can more easily identify the end face when using the nixie tube.

When the end surface of the light shield 14 close to the display portion 20 is a transparent surface, light emitted from the light emitting end of the nixie tube 122 can be directly emitted to the display portion 20 through the transparent surface and displayed outside the housing 10, so that a user can more easily identify the use state of the induction cooker (e.g., power on, power off, etc.) or the working mode of the induction cooker (e.g., heating, heat preservation, stir-frying, boiling water, etc.) when using the induction cooker.

When the light shield 14 is provided with a light guide coating on the inner wall surface close to the display portion 20, the light emitted from the light emitting end of the nixie tube 122 passes through the light guide coating and is emitted to the display portion 20.

In a possible implementation manner, referring to fig. 9, a clasp 131 protruding toward the circuit board 12 may be disposed on an outer wall of the light shielding member 13, and an opening 121 may be disposed on the circuit board 12 at a position corresponding to the clasp 131, so that the clasp 131 is engaged in the opening 121 during assembly, thereby completing the assembly between the light shielding member 13 and the circuit board 12, which is simple and convenient for a user to operate.
