Abstract
Description
Technical Field
[0001] The utility model relates to a smoking device, and more specifically, to a smoking device. Background Art
[0002] The smoking device is an uncapped tank for containing gas. An air tank is arranged in the tank, and tobacco is directly contained in the air tank. It is directly ignited from the outer shell, and the heat is conducted from the outer shell to the tank body. The tank body transfers the heat to the air tank, thereby igniting the tobacco in the air tank to release gas, and the gas escapes from the smoke outlet.
[0003] Currently, since the smoking device on the market cannot control the opening and closing of the smoke outlet, it cannot control the escape and interruption of cigarette gas. Therefore, the size of the smoking device can only be made small, and the air tank needs to be frequently replaced, making the smoking device inconvenient to use. Summary of the Utility Model
[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a smoking device. The utility model can control the escape and closing of cigarette gas, and can also control the flow rate of the escaped cigarette gas, so that the air tank does not need to be frequently replaced, making it more convenient for users.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A smoking device, comprising an outer shell and a cigarette holder. An air tank is arranged in the outer shell. A control valve is installed between the outer shell and the cigarette holder. The control valve includes a valve body, a valve core and an operating member. The valve body is provided with a smoke inlet, a receiving cavity and a smoke outlet. The smoke inlet and the smoke outlet are communicated with the receiving cavity. One end of the smoke inlet of the valve body is communicated with the inner cavity of the outer shell. The cigarette holder is communicated with the smoke outlet of the valve body. The operating member is connected to the outer end of the receiving cavity and cooperates with the valve core.
[0006] By adopting the above technical solution, by driving the operating member to cause the valve core to move to control the conduction or closing between the smoke inlet and the smoke outlet, the size of the smoking device can be made larger, so that the user reduces the number of times of replacing the air tank and uses it more conveniently.
[0007] The utility model is further provided as: The operating member includes a handwheel and a screw rod portion arranged on the handwheel. The screw rod portion is threadedly connected with the inner wall of the receiving cavity. The valve core is a steel ball.
[0008] By adopting the above technical solution, by tightening and loosening the screw rod portion, the opening and closing of the steel column for controlling the smoke inlet and the flow rate of the smoke outlet are controlled.
[0009] The utility model is further provided as: A third sealing ring for forming a sealing fit with the inner wall of the receiving cavity is arranged on the outer periphery of the screw rod portion.
[0010] By adopting the above technical solution, good sealing performance is ensured between the operating part and the valve body to prevent gas from escaping from the connection between the operating part and the valve body.
[0011] The present utility model is further configured as: the outer shell includes an upper shell and a lower shell, the upper shell and the lower shell are connected by threads, and a second sealing ring is provided at the threaded end of the lower shell.
[0012] By adopting the above technical solution, the gas cylinder can be conveniently replaced, and good sealing performance can be ensured between the upper and lower shells to prevent gas from escaping from between the upper and lower shells.
[0013] The present utility model is further configured as: one end of the smoke inlet of the valve body is connected to the outer shell by threads, and a third sealing ring is provided at the end of the threaded part of the outer shell.
[0014] By adopting the above technical solution, good sealing performance is ensured between the valve body and the outer shell to prevent gas from escaping from the connection between the valve body and the outer shell.
[0015] The present utility model is further configured as: the cigarette holder is inserted into one end corresponding to the smoke outlet of the valve body, and a limiting step for forming a stroke limit for the cigarette holder is provided on the valve body.
[0016] By adopting the above technical solution, the limiting step ensures that the installation position of the cigarette holder will not shift. If installed too shallowly, the cigarette holder is likely to become loose, and if installed too deeply, it is likely to damage the cigarette holder.
[0017] The present utility model is further configured as: a fourth sealing ring for forming a sealing fit with the inner wall of the cigarette holder is installed on the outer periphery of the valve body.
[0018] By adopting the above technical solution, good sealing performance is ensured between the valve body and the cigarette holder to prevent gas from escaping from the connection between the valve body and the cigarette holder.
[0019] The present utility model is further configured as: the cigarette holder is a straight-mouth cigarette holder or a bent-mouth cigarette holder.
[0020] By adopting the above technical solution, different cigarette holders meet the holding habits of different people when smoking.
[0021] The present utility model is further configured as: a criss-crossed groove part is circumferentially arranged on the side wall of the outer shell.
[0022] By adopting the above technical solution, not only the aesthetic degree of the cigarette smoking device is increased, but also it is not easy to slip when used by the user in the hand.
[0023] The present utility model is further configured as: knurling is provided on the hand wheel.
[0024] By adopting the above technical solution, it is easier for the user to rotate the hand wheel and no slipping phenomenon will occur. BRIEF DESCRIPTION OF THE DRAWINGS
