Brief Description of the Drawings

[0015] Figure 1 It is a schematic structural diagram of a cap structure with multiple wires of the present utility model.

[0016] Wherein: wire 1, bell tube 2, exhaust pipe 3. Detailed Embodiment

[0017] The present utility model will be further clearly and completely described below in conjunction with the drawings and the detailed embodiment. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restricts the present utility model and its application or use. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present utility model.

[0018] It should be noted that the terms used here are only for describing the detailed embodiment, rather than intending to limit the exemplary embodiments according to the present application. As used here, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or their combinations.

[0019] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present utility model. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0020] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" are generally based on the orientation or positional relationships shown in the drawings. These are only for the convenience of describing the present utility model and simplifying the description. Without contrary statements, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the protection scope of the present utility model; the orientation words "inner, outer" refer to the inside and outside relative to the contour of each component itself.

[0021] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above-mentioned" can be used here to describe the spatial positional relationships between a device or feature shown in the drawings and other devices or features. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation described in the drawings for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0022] In addition, it should be noted that the use of words such as "first", "second", etc. to limit components is only for the convenience of differentiating the corresponding components. Without additional statements, the above words have no special meanings. Therefore, they should not be construed as limiting the protection scope of the present utility model.

Specifically, both the horn tube 2 and the exhaust pipe 3 are made of hard glass material. The top end of the horn tube 2 is hermetically sealed together with the upper ends of the guide wires 1 and the exhaust pipe 3. The lower end of the horn tube 2 is turned outwards into a horn shape. The upper end of the exhaust pipe 3 does not protrude from the top surface of the horn tube 2. The lower end of the exhaust pipe 3 extends to the outside of the bottom surface of the horn tube 2. Further, a first air hole and a second air hole which are communicated with each other are respectively arranged at the upper and lower ends of the exhaust pipe 3, and the first air hole is communicated with the outside of the top surface of the horn tube 2.

[0024] The guide wire 1 includes a power-on guide wire and a functional guide wire. At least two of each of the power-on guide wire and the functional guide wire are provided, and the power-on guide wires are located outside the functional guide wires.
