Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of portable smoke machine, specifically relates to a smoke cartridge structure and smoke machine. BACKGROUND

[0002] The stage smoke machine is used for spraying white gaseous smoke by spraying smoke oil containing chemical components that can be quickly gasified after being heated by a high-temperature heating pipe, so as to achieve a good stage effect. However, the stage smoke machine is large in size and inconvenient to carry, and its use is limited.

The smoke cartridge is provided with an air passage, and the white smoke after atomization is sprayed from the air passage. The host is mainly used for supplying power and air source. The power can be supplied to the smoke cartridge to continuously heat and atomize the smoke cartridge. The air source is mainly used for blowing the smoke cartridge to blow out the white smoke after atomization, forming a spraying effect.

If the liquid guide opening of the liquid guide compartment is set to be small, the atomizing agent with certain viscosity will stick to the side wall and cannot flow into the liquid guide opening. If the liquid guide opening of the liquid guide compartment is set to be large, a large amount of atomizing agent will directly enter the atomization compartment, which is easy to cause the atomizing agent to leak from the air passage.

[0005] However, the existing part machining error and the assembly error between parts are difficult to guarantee the size precision of the liquid guide opening of the liquid guide compartment, resulting in a high rejection rate of the existing smoke cartridge after assembly.

[0034] The lateral wall of inner shell 21 is equipped with through hole 211, and oil leading piece 22 is liquid conducting material, and oil leading piece 22 can guide liquid while blocking through hole 211, and the importation of atomizing agent can be effectively controlled. In the application, through hole 211 is directly formed in the lateral wall of inner shell 21, and the setting of the liquid guiding bin is cancelled, the problems of poor atomizing agent importation and leakage are avoided, and the defective rate of the cartridge structure after assembly is effectively reduced.

[0035] Specifically, the outer shell 12 is made of transparent glass material, which facilitates observation of the liquid condition in the liquid storage bin 14. The connection between the outer shell 12 and the top cover 13 and the connection between the outer shell 12 and the base 11 are both sealed to prevent the liquid in the liquid storage bin 14 from leaking out. In this embodiment, in order to facilitate the installation of the atomization subassembly 2, the base 11 and the outer shell 12 are connected in a detachable manner. That is, after the atomization subassembly 2 is installed inside the outer shell 12, the base 11 is then installed at the bottom end of the outer shell 12 to seal the liquid storage bin 14. The top of the top cover 13 is provided with an oil filling port, which is blocked by a soft rubber plug. When it is necessary to supplement the liquid oil, the soft rubber plug is opened and the oil is filled through the oil filling port. The connection position between the outer shell 12 and the top cover 13 and the connection position between the outer shell 12 and the base 11 are both provided with soft rubber, which seals the connection positions in a soft rubber sealing manner.

[0037] Specifically, the mounting seat 25 and the base 11 are integrally formed by machining. The outer diameter of the mounting seat 25 is smaller than that of the base 11. The mounting seat 25 is provided with a positive connector 26 and a negative connector 27. The positive electrode of the heating element 23 is connected to the positive connector 26, and the negative electrode of the heating element 23 is connected to the negative connector 27.

One end of the inner shell 21 is connected to the air inlet channel 111, and the other end is connected to the mist outlet channel 131. The outer edge of the mounting seat 25 is provided with a connecting table 251. One end of the inner shell 21 is buckled on the connecting table 251 and is in airtight connection with the connecting table 251, preventing the atomizing agent in the liquid storage compartment 14 from directly penetrating in. The outer side of the base 11 is provided with a connecting screw 15. The connecting screw 15 passes through the base 11 into the inside of the support shell 1 and connects the inner shell 21 to fix one end of the inner shell 21 on the connecting table 251, realizing the sealed connection between the inner shell 21 and the connecting table 251. The bottom of the top cover 13 is provided with a threaded interface 132. The mist outlet channel 131 penetrates the threaded interface 132, and the other end of the inner shell 21 is screwed to the threaded interface 132. Through the threaded connection, the inner shell 21 and the threaded interface 132 are tightly connected, so that the smoke is smoothly sprayed out of the mist outlet channel 131.

[0038] In this embodiment, the assembly process of the cartridge structure is as follows:

[0039] First, the heating element 23 is installed on the positive connector 26 and the negative connector 27. After assembly, one end of the inner shell 21 is buckled on the connecting table 251 of the mounting seat 25. The inner shell 21 is rotated so that the screw holes on the inner shell 21 are opposite the screw holes on the base 11. Then the connecting screw 15 is installed. The connecting screw 15 passes through the base 11 into the screw hole of the inner shell 21. The connecting screw 15 is locked to fix one end of the inner shell 21 on the connecting table 251.

[0040] Then the oil guiding element 22 is installed. The oil guiding element 22 is a flexible fiber fabric material with good temperature resistance or a solid material with small gaps. The oil guiding element 22 passes through the through hole 211 of the side wall of the inner shell 21 and connects the heating element 23. After installation, the oil guiding element 22 is tightly squeezed and can block the through hole 211 to prevent the atomizing agent from directly penetrating from the through hole 211.

[0041] Finally, the above-mentioned partially assembled parts are installed with the top cover 13 and the outer shell 12. Since the outer shell 12 and the top cover 13 are fixedly connected and cannot be disassembled, in order to prevent the two from separating, the two are glued after being assembled with interference fit to strengthen the connection stability between the two. When the above-mentioned partially assembled parts are installed, the end of the inner shell 21 is directed towards the open end of the outer shell 12, and the threaded end of the inner shell 21 is ensured to be aligned with the threaded interface 132, and then screwed. After the inner shell 21 is screwed and connected with the threaded interface 132, the base 11 also completes the snap-fit installation with the outer shell 12, and at this time the cartridge structure is completed.

[0042] The heating element 23 is an electrically resistive wire made of a metal with good heat resistance. The resistance value of the electrically resistive wire is 0.05 to 25 ohms, for example: the electrically resistive wire is made of stainless steel or nickel alloy or tungsten wire. The shape of the electrically resistive wire is spiral or tubular or reticular or sheet, which can be designed according to actual conditions. Due to the separation effect of the inner shell 21, the liquid storage chamber 14 and the atomization chamber 24 are two independent spaces, the atomizing agent in the liquid storage chamber 14 is supplied to the heating element 23 through the oil guiding element 22, and the heating element 23 only heats the limited atomizing agent on the oil guiding element 22, effectively reducing the heating load of the heating element 23, and the product realizes instantaneous atomization and low power consumption.

[0043] The oil guiding element 22 is a flexible fiber fabric material with good temperature resistance or a solid material with micro voids. It can penetrate the atomizing agent from the wetter side to the drier side through the capillary principle. Common flexible fabric materials are, for example: cotton, glass fiber, asbestos, etc. Solid materials with micro voids are, for example: porous ceramics with rich voids, diatom mud, gypsum, cement, etc. Since the oil supply scheme adopts the capillary principle, the atomizing agent in the liquid storage chamber 14 continuously penetrates into the heating element 23 under the action of negative pressure and penetration, continuously repeating the atomization process.

[0044] In this embodiment, the heating element 23 is spiral-shaped and encloses a through hole, and the oil guiding element 22 adopts a cotton core, which passes through the through hole, and the heating element 23 wraps the main body of the cotton core. The cotton core continuously adsorbs the atomizing agent from the liquid storage chamber 14 to the heating element 23 position for heating and vaporization to generate smoke. In order to increase the atomization amount of the atomizing agent, two through holes 211 are provided on the side wall of the inner shell 21 in opposite positions. The oil guiding element 22 passes through the heating element 23 and is fixed on the heating element 23, and the two ends of the oil guiding element 22 pass through the corresponding through holes 211 and block the through holes 211. In order to facilitate the installation of the oil guiding element 22, the through hole of the heating element 23 is aligned with the through hole 211 of the inner shell 21, and then the oil guiding element 22 passes through the through hole 211 and the through hole. In order to make full use of the atomizing agent at the bottom of the liquid storage chamber 14, at least one end of the oil guiding element 22 extends to the bottom of the liquid storage chamber 14, facilitating the absorption of the atomizing agent at the bottom of the liquid storage chamber 14.
