[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0032] It should be noted that the left, right, up, down, front, back and other orientation terms in the embodiments of the utility model are only relative concepts or are referenced to the normal use state of the product, i.e. the advancing direction of the product, and should not be considered as limiting.

[0033] Finally, it needs to be noted that when a component is referred to as "on" or "disposed on" another component, it can be directly on the other component or can be present in the middle of other components. When a component is referred to as "connected to" another component, it can be directly connected to the other component or can be present in the middle of other components.

[0034] As Figures 1 to 7 shown, a smoking mouthpiece is installed at the end of the barrel, and the smoking mouthpiece comprises a connecting part 1, a smoking mouthpiece body 2, a smoking mouthpiece slope 3, and a high-temperature-resistant transparent glass cover 4. The connecting part 1 is elastically connected to the elbow 6. The circumference of the smoking mouthpiece body 2 contains a smoking hole 12, and the high-temperature-resistant transparent glass cover 4 is installed above the smoking hole 12 and connected to the smoking mouthpiece body by high-temperature-resistant glue 5. Specifically, the high-temperature-resistant transparent glass cover 4 comprises a glass inclined plate at the top and glass side plates on the left and right sides. The bottom end surface of the high-temperature-resistant transparent glass cover 4 composed of the glass inclined plate and the glass side plates on the left and right sides is fixedly connected to the smoking mouthpiece body 2 around the smoking hole 21 by high-temperature-resistant glue 5, and the opening of the high-temperature-resistant transparent glass cover 4 faces the head end of the smoking mouthpiece body 2. The high-temperature-resistant transparent glass cover 4 and the smoking hole 12 form a smoking port with a focused smoking area, improving the smoking effect. The high-temperature-resistant transparent glass cover 4 is made of transparent high-temperature-resistant material, reducing the shielding and facilitating the observation of the operation during the welding process.

[0035] In the embodiment, the connecting part 1 of the new smoking mouthpiece is elastically connected to the elbow 6 by the claw 12 and the elastic snap ring 11, which helps to quickly install and disassemble the smoking mouthpiece.

[0036] Preferably, the elastic connection can adjust the smoking port to the position where smoke is generated in the axial and circumferential directions according to different use scenarios, improving the smoking effect.

[0037] In the embodiment, the new smoking mouthpiece body 2 and the high-temperature-resistant transparent glass cover 4 are installed above the smoking hole 12 and connected to the smoking mouthpiece body by high-temperature-resistant glue 5. The high-temperature-resistant transparent glass cover 4 and the smoking hole 12 form a smoking port with a focused smoking area, and the elongated eaves 41 of the transparent glass cover block the air other than smoke from entering the smoking mouthpiece, further strengthening the suction of smoke.

[0038] Further, the new smoking mouthpiece body 2 and the high-temperature-resistant transparent glass cover 4 form a variable cross-section smoking channel, with the largest opening at the front end and the smallest cross-section in the middle. The large opening at the front end is conducive to the suction of the smoke coverage, and the small cross-section in the middle increases the negative pressure of the channel, improving the smoking effect.

[0039] Preferably, the high-temperature-resistant transparent glass cover 4 is made of transparent high-temperature-resistant material, reducing the shielding and facilitating the observation of the operation during the welding process.

[0040] In the embodiment, the slope surface 3 of the cigarette holder is a large slope surface, which reduces the shielding of the cigarette mouth, increases the smoothness of the path of the smoke dust being inhaled into the cigarette mouth, and improves the smoking effect.

[0041] In the embodiment, the outer diameter of the cigarette holder body ranges from 20 to 50 mm. The material of the cigarette holder body is preferably aluminum, and secondarily includes but is not limited to copper, steel, ceramic, glass, etc. The width of the high-temperature-resistant transparent glass cover ranges from 10 to 50 mm. The material of the high-temperature-resistant transparent glass cover body is preferably glass, and secondarily includes but is not limited to copper, steel, ceramic, aluminum, etc. The angle of the glass inclined plate ranges from 5° to 60°.

[0042] The above only describes the preferred embodiments of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
