Abstract
Description
Technical Field
[0001] This utility model relates to electric tobacco pipes, and more particularly to a mouthpiece for electric tobacco pipes. Background Technology
[0002] Hookah is a method of smoking tobacco products using a special tool called a "hookah" that filters the tobacco through water (or other liquid). Currently, hookahs used by multiple users have angled mouthpieces. These mouthpieces contain a ball bearing that gravity-seales the smoke passage. During smoking, the ball bearing detaches from the smoke passage under the force of suction. This design allows for both multi-user and individual use without switching, making it convenient. However, due to the automatic sealing structure, multi-mouth hookahs typically achieve smoke extraction by switching internal channels. This switching complicates the internal structure and puts pressure on space-saving design. Summary of the Invention
[0003] The purpose of this utility model is to provide a cigarette holder for an electric hot water bottle that is simple in structure, easy to implement, and can conveniently achieve smoke exhaust for multi-mouth electric hot water bottles.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a mouthpiece for an electric tobacco pipe, the electric tobacco pipe including a body with at least two mouthpiece assemblies, the mouthpiece assembly being horizontally connected to the body via a mouthpiece connector, the mouthpiece connector being connected to a smoking channel within the body, the mouthpiece assembly including an air cavity and a rotatable ball bearing disposed in the middle section of the air cavity, the air cavity being coaxially arranged from the outside to the inside including an external connecting section communicating with the outside, a middle section allowing the ball bearing to move freely, and a frustum-shaped connecting section communicating with the smoking channel with an inner diameter smaller than that of the middle section, the smaller diameter end of the connecting section connecting to the connecting section with an inner diameter smaller than that of the ball bearing, the larger diameter end of the connecting section connecting to the middle section with an inner diameter larger than that of the ball bearing, the inner length of the middle section being much larger than that of the ball bearing.
[0005] As an improvement: a stop is provided at the connection between the external connecting section and the intermediate section to prevent the ball bearings from falling out, and the stop has a vent hole.
[0006] As an improvement: the external connecting section is detachably connected to the air cavity, and a connecting sleeve is also sleeved between the external connecting section and the intermediate section, with the radial surface of one end of the connecting sleeve serving as a door stop.
[0007] As an improvement, the vent is eccentrically positioned on the door stop.
[0008] As an improvement, the inner diameter of the smaller diameter end of the connecting section is larger than the radius of the ball bearing.
[0009] The beneficial effects of this utility model are: the mouthpiece can be used on hookahs with multiple mouthpieces for multiple people to use at the same time, and can also be used to blow smoke, even multiple people blowing smoke, to meet the different needs of users. It has a simple structure and is easy to use. In the non-smoking standby state, the ball bearing, due to the horizontal placement of the mouthpiece, is positioned in the middle section under gravity. Since the diameter of the middle section is larger than the diameter of the ball bearing, a connection is formed above the ball bearing, creating an air passage that is open despite the obstruction of foreign objects. During inhalation, the ball bearing in the user's mouthpiece remains in the middle section, away from the connection point, due to the suction force. Meanwhile, in other mouthpieces not inhaled, the ball bearing, due to the suction force, moves across the connecting section and blocks the connection point, thus sealing the air passage in those mouthpieces. No switching is required; the mouthpieces automatically open and close based on inhalation. When expelling smoke, a gentle blow into the mouthpiece prevents the ball bearing from completely sealing the air passage due to the slope of the frustum-shaped side of the connecting section. The blown air enters the smoking channel, and since other unused mouthpieces are also open due to the lack of suction, the air is expelled from these unused mouthpieces or forms a smoke ring. This exhaust system can be used by one person or multiple people. When multiple people are using it, only one mouthpiece needs to be left as the exhaust port. The mouthpiece will not put pressure on the internal structure of the kettle, and it is highly versatile and compatible.
[0010] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0015] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this utility model discloses an embodiment of a mouthpiece for an electric tobacco pipe. The electric tobacco pipe includes a body 1 with at least two mouthpiece assemblies. This embodiment provides a double-mouthlet electric tobacco pipe, but the mouthpiece of this utility model is also applicable to electric tobacco pipes with multiple mouthpieces or a single mouthpiece, demonstrating strong compatibility. The mouthpiece assembly is horizontally connected to the body of the pipe via a mouthpiece connector 11, which connects to the smoking channel within the pipe body. The mouthpiece assembly includes an air cavity 2 and a rolling ball 3 disposed in the middle section of the air cavity. The horizontally positioned mouthpiece assembly ensures the free rolling of the ball within, and is a non-gravity-driven opening and closing structure. The air cavity is coaxially arranged from the outside to the inside, including an external connecting section 21 that connects to the outside, a middle section 22 that allows the ball to move freely, and a frustum-shaped connecting section 23 that connects to the smoking channel and has an inner diameter smaller than the middle section 22. The smaller diameter end of the frustum-shaped connecting section 23 connects to the connecting section 24, and the inner diameter of this end is smaller than the diameter of the ball bearing. The larger diameter end of the connecting section 23 connects to the middle section, and the inner diameter of this end is larger than the diameter of the ball bearing. The inner length of the middle section 22 is much larger than the diameter of the ball bearing. The angle of the frustum-shaped cone of the connecting section 23 is greater than the angle formed by the tangent of the ball bearing at the connecting opening, so that the slope of the connecting section cannot cause the ball bearing to stop. This taper can be adjusted according to the blowing volume. In this embodiment, the inner diameter of the smaller diameter end of the connecting section 23 is larger than the radius of the ball bearing, so that the opening of the connecting opening is large enough to avoid the situation where the ball bearing is not in place and is closed. That is, the ball bearing can only close the connecting opening after climbing over the slope and reaching the position. Moreover, the ball bearing falls back quickly after the force is released, corresponding to the inhalation and blowing situation at the mouthpiece in real time. To prevent the ball bearing from detaching from the mouthpiece and to reasonably limit the ball bearing's rolling stroke length, this embodiment features a stop 25 at the connection between the outer connecting section 21 and the intermediate section 22 to prevent the ball bearing from detaching. The stop 25 has a vent 26, which is eccentrically positioned on the stop 25. This eccentric positioning prevents the ball bearing from exceeding the connecting section's closing position due to excessive blowing force. For ease of assembly and maintenance, the outer connecting section in this embodiment is detachably connected to the air duct. The stop is also designed with a connecting sleeve end face; that is, a connecting sleeve 27 is fitted between the outer connecting section 21 and the intermediate section 22, with one end of the connecting sleeve forming the stop 25. The outer connecting section and the connecting sleeve are sequentially fitted onto the outward-facing end of the intermediate section 22. This reasonable structure allows for easy smoke extraction with a light breath, resulting in a clear and concise internal structure for the kettle and the entire machine.
[0016] Although the present invention has been disclosed above with specific embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of the appended claims.
