A smoking set used for heating cigarette sticks with liquid injection

technical field

The invention belongs to the technical field of electronic smoking utensils, and in particular relates to a smoking utensil for injecting liquid into cigarettes and heating them.

Background technique

With the deepening of the tobacco control campaign and the public's awareness of the health hazards of smoking, the development of new tobacco products has received increasing attention. Studies have shown that most of the harmful components in traditional cigarette smoke are produced by pyrolysis, thermal synthesis and other reactions during the high-temperature combustion process of tobacco. The way to generate flue gas can reduce most of the reactions such as pyrolysis and thermal synthesis, and reduce the release of harmful components in the flue gas as a whole. At present, new types of tobacco products at home and abroad mainly include electronic cigarettes, low-temperature non-combustible cigarettes, and snus. Among them, electric heating cigarettes make tobacco products smoke in the form of heat-not-burn, so that users can experience the physiological feeling, psychological perception, and smoking experience of smoking. The method and other aspects are closest to traditional cigarettes, and can meet the smoking needs of users to a certain extent.

Among them, heat-not-burn cigarette products are mainly composed of two parts: cigarette sticks and heating devices. The appearance of cigarette sticks is basically the same as that of ordinary cigarettes, which conforms to the characteristics of heat-not-burn cigarettes.

However, due to the different temperatures under the cigarette, different tastes are produced.

While ordinary cigarettes, when smoked under the condition of heating without burning, their mouthfeel cannot reach the effect after being ignited and smoked, so in order to ensure the mouthfeel, cigarettes used as heated cigarettes are generally specially made, and their internal structure is greatly different from that of ordinary cigarettes. the difference. Conversely, cigarettes used as heated cigarettes cannot achieve the expected taste by lighting and smoking.

Now there is a heated smoking set on the market. After adding additives to ordinary cigarettes, it is smoked in a heat-not-burn manner. The smoking set and the additive-added appliance are two independent parts. In actual use, There are troubles in use and inconvenience in carrying.

Contents of the invention

The object of the present invention is to provide a smoking utensil for heating cigarettes by injecting liquid, which is used to solve the problems of troublesome use and inconvenient carrying caused by structural defects of existing smoking utensils.

For realizing above-mentioned technical purpose, the technical scheme that the present invention adopts is as follows:

A heating chamber is opened on the main body, and a heating chamber is vertically slid in the heating chamber to install the main body. The bottom of the heating cylinder is fixed with a cigarette holder. The inner diameter of the cigarette holder is smaller than the diameter of the cigarette. There is a notch on the main body, the connecting block is located in the notch, the free end of the connecting block is fixedly connected with a push block outside the main body, and the bottom end of the main body is detachably installed with a liquid injection device for quantitative injection of additives. The liquid injection cylinder is equipped with a liquid injection needle in the accommodating cavity, and a section of the liquid injection needle away from the liquid injection cylinder is uniformly provided with a plurality of sets of hole groups, and each group of hole groups includes a number of circumferentially distributed injection holes. There is a liquid hole, and an accommodating cavity for placing a liquid injection cylinder and a liquid injection needle is opened on the main body.

It is further defined that sliders are fixed on both sides of the heating cylinder, sliding grooves are opened on the side walls of both sides of the heating chamber on the main body, and the sliders are located in the sliding grooves. With such a structural design, the sliding connection between the heating cylinder and the main body is completed through the mutual cooperation of the slider and the chute, and then the heating cylinder is vertically slidably installed in the heating chamber of the main body. The structure is simple and the installation is convenient.

It is further defined that a hemispherical groove is formed on the outer wall of the slider, and two threaded holes are formed in the main body in the sliding groove, and a ball plunger is screwed into the threaded holes. With such a structural design, the positioning of the heating cylinder is completed through the mutual matching of the ball plunger and the hemispherical groove, so that when the heating cylinder is pushed to a specific position, it is fixed by the ball plunger, which is more convenient to use.

It is further defined that the liquid injection cylinder includes a partition, an outer cylinder and an inner cylinder, the partition is located in the middle section of the outer cylinder, the inner cylinder is fixed on the partition, and the inner cylinder is located in the outer cylinder In the body, the liquid injection needle is installed on a partition, a liquid tank loaded with an additive liquid is detachably installed between the outer cylinder and the inner cylinder, and an injection channel and an inlet flow are opened on the partition. The injection channel communicates with the inner cylinder and the liquid injection needle, and the first check valve is arranged in the injection channel, and the liquid inlet channel communicates with the injection channel and the liquid chamber, and the liquid inlet channel A second one-way valve is arranged inside, and a piston is slidably installed in the inner cylinder, and the piston is connected with a push-pull rod. With such a structural design, after the liquid injection cylinder is installed on the preset position of the main body, the push-pull rod is pulled to move the push-pull rod to drive the piston to move downward. During this process, the first one-way valve is in a closed state, and the second one-way valve The valve is in the open state, so that the additive in the liquid tank is drawn into the inner cylinder through the liquid inlet channel, until the push-pull rod is pulled to the end; then press the outer cylinder with your fingers, and then push the push-pull rod back, through The push-pull rod drives the piston to move upwards. During this process, the first one-way valve is in the open state, and the second one-way valve is in the closed state, so that the additive in the inner cylinder enters the injection needle through the injection channel, and then from the injection needle. The needle enters the cigarette to complete the addition of additives to the cigarette.

It is further defined that the limit ring is screwed to the end of the inner cylinder away from the partition, the push-pull rod is passed through the limit ring, the push-pull rod is covered with a limit sleeve rod, and the limit sleeve rod is located on the piston. and the limit ring. With such a structural design, the maximum downward movement distance of the piston is limited by the limit ring and the limit sleeve. The limit sleeve rod leans against the limit ring, and then pushes up to the end to ensure the same amount of liquid injection each time; at the same time, it can also prevent the piston from detaching from the inner cylinder, which is more practical; moreover, through the limit sleeve rod The maximum downward movement distance of the piston can be further reduced, and the liquid injection volume standard for a single injection can be modified by replacing the limit sleeve rods with different lengths and sizes, so as to correspond to different cigarettes or different uses The user's usage habits, the scope of application is wider.
