Technical Field

[0001] This utility model relates to the field of smoke generating equipment, and in particular to a smoke generating device. Background Technology

[0002] To adapt to the shooting needs of various scenarios and improve shooting effects, portable small fog machines, which are different from large fog machines, have appeared on the market.

[0003] Existing portable vaporizers primarily rely on a vapor generator to produce vapor, with e-liquid entering the atomizing chamber of the vapor generator for atomization. During atomization, some of the vapor liquefies after moving away from the heating wire, collecting on the absorbent cotton and dripping down. This accumulated e-liquid dripping into the air intake pipe can clog it and easily damage the air pump. Utility Model Content

[0004] The purpose of this invention is to provide a smoke generator with an oil-leakage prevention structure, which can significantly reduce the probability of smoke oil entering the air intake pipe.

[0005] This utility model provides a smoke generating device, including a base, a heating wire, and a fixing assembly for fixing the heating wire. The smoke generating device includes an air inlet pipe and a guide protrusion, wherein the guide protrusion is fitted to the air inlet pipe and is disposed on the outside of the air inlet pipe. The height of the guide protrusion near the upper end face of the heating wire is higher than or equal to the height of the air inlet pipe near the top end of the heating wire. The guide protrusion is provided with a sloped guide portion for guiding liquid.

[0006] Preferably, the air guide and the air intake pipe are coaxially arranged.

[0007] Preferably, the guide portion extends downward at an angle from the side near the air intake pipe to the side away from the air intake pipe, and the lower end of the guide portion protrudes from the outer wall of the air intake pipe.

[0008] Preferably, the guide boss and the air intake pipe are mounted on the base, and the base is provided with at least one connecting hole penetrating the base.

[0009] Preferably, the heating wire is disposed above the flow guide protrusion, and both ends of the heating wire are fixed to the base.

[0010] Preferably, the smoke generating device further includes an upper cover, a housing, and a bottom cover connected in sequence, with a smoke outlet extending from the middle of the upper cover away from the housing, and the upper cover forming at least one oil inlet around the smoke outlet.

[0011] Preferably, the shell has a hollow interior forming a first cavity, an atomizing chamber is provided in the first cavity, the atomizing chamber has a hollow interior forming a second cavity, the first cavity and the second cavity are connected through the connecting hole, the smoke outlet is connected to the second cavity, and the oil inlet is connected to the first cavity.

[0012] Preferably, the base is disposed at the bottom of the second cavity and partially encloses the second cavity.

[0013] Preferably, the smoke generating device further includes an air supply component, which is disposed at the bottom end of the air inlet pipe and is used to supply air to the air inlet pipe.

[0014] Preferably, the bottom cover extends downward from the middle to form a connector, and the outer wall of the connector is threaded for connection with the smoke machine.

[0015] As described above, the smoke generator of this invention adds a guide protrusion above the air inlet pipe, with the guide protrusion, rather than the air inlet pipe, having a guide portion. The air inlet pipe does not protrude beyond the guide protrusion, and the guide portion of the guide protrusion is wider, significantly improving the oil guiding effect and reducing the probability of e-liquid entering the air inlet pipe.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Please see Figure 1 and Figure 2 A smoke generating device 100 is used to generate smoke when installed on a smoke generator. The smoke generating device 100 includes, from top to bottom, an upper cover 10, a housing 30, and a bottom cover 50. Further, the housing 30 has a hollow interior forming a first cavity 31, within which an atomizing chamber 33 is disposed, and the atomizing chamber 33 has a hollow interior forming a second cavity 331. The inner walls of the atomizing chamber 33 and the first cavity 31 are spaced apart, meaning the outer wall of the atomizing chamber 33 and the inner wall of the first cavity 31 do not contact each other. An air intake assembly 40 is disposed in the second cavity 331 near the bottom cover 50. A heating wire 35 is disposed above the air intake assembly 40 and is fixed by a fixing assembly.

[0028] Please see Figures 2-4When the e-liquid approaches the heating wire 35, it is atomized into smoke by high temperature and discharged from the smoke outlet 13. During the smoke discharge process, some of the smoke liquefies back into e-liquid and collects above the air intake pipe 43 through the oil-absorbing cotton (not shown). After the e-liquid accumulates to a certain amount, it drips downwards due to gravity. If it drips into the air intake pipe 43, it will block the pipe, causing poor air intake, damage to the air pump, and even affecting the smoke output effect. To solve this problem, this utility model provides an oil-leakage-proof air intake structure. In this embodiment, the air intake assembly 40 includes a base 41, an air intake pipe 43, a guide protrusion 45, and a fixing seat 47. Specifically, one end of the air intake pipe 43 is inserted into the bottom of the base 41 and protrudes from the inner wall of the base 41, while the other end extends through the bottom cover 50 to the outside of the bottom cover 50. That is, the guide protrusion 45 is attached to the air intake pipe 43 and is located on the outside of the air intake pipe 43. It is understood that the guide protrusion 45 can be attached to the air intake pipe 43 by friction or other means. The guide protrusion 45 is fixed to the fixing base 47 and mounted on the base 41. The guide protrusion 45 is provided with an air outlet 451 that passes through the upper and lower end faces of the guide protrusion 45. One end of the air intake pipe 43 is inserted into the air outlet 451, so that the air outlet 451 is connected to the air intake pipe 43. The upper end face 457 of the guide protrusion 45 protrudes relative to the top end 431 of the air intake pipe 43, that is, the height of the upper end face 457 of the guide protrusion 45 near the heating wire 35 is higher than or equal to the height of the top end 431 of the air intake pipe 43 near the heating wire 35. The air intake pipe 43 does not protrude from the upper end face 457 of the guide protrusion 45, thereby avoiding the situation where the air intake pipe 43 is directly exposed to the e-liquid. A guide portion 453 is circumferentially arranged around the air outlet 451, meaning the guide portion 453, air outlet 451, and air inlet pipe 43 are coaxially arranged. The guide portion 453 is used to guide liquid flow, which can be e-liquid or liquid formed by liquefaction of vapor. In this embodiment, the guide portion 453 extends downward at an angle from the side near the air inlet pipe 43 to the side away from the air inlet pipe 43, until the lower end of the guide portion 453 protrudes from the outer wall of the air inlet pipe 43, forming approximately a downwardly sloping surface. It is understood that the guide portion 453 can also be designed in other shapes, depending on actual needs. It is understood that the guide portion 453 can be located at other positions on the guide boss, depending on actual needs. The guide boss 45 can increase the width of the guide portion 453, thus improving the guiding effect of the guide portion 453. When e-liquid drips onto the guide protrusion 45, it flows along the guide section 453 to the surrounding area into the first cavity 31, where it is heated and atomized again by the heating wire 35. This significantly reduces the probability of e-liquid flowing into the air intake pipe 43 and also enables the secondary use of e-liquid.

[0029] Furthermore, this embodiment provides a guide boss 45. Compared to directly providing a guide portion 453 on the intake pipe 43, the guide portion 453 of the guide boss 45 is wider and has a better guiding effect.

[0030] Furthermore, the heating wire 35 is positioned directly above the air outlet 451, ensuring that the air outlet 451 remains at a high temperature during operation. When e-liquid drips into the air intake pipe 43, the high temperature will re-atomize the e-liquid, reducing the probability of e-liquid flowing into the air intake pipe 43. Simultaneously, the guide protrusion 45 increases the distance e-liquid needs to travel to enter the air intake pipe 43, increasing the probability of e-liquid atomization and reducing the probability of e-liquid flowing into the air intake pipe 43.

[0031] Furthermore, the base 41 includes a first fixing part 411, and the guide boss 45 includes a second fixing part 455, with the first fixing part 411 and the second fixing part 455 arranged at intervals relative to each other. The two ends of the heating wire 35 are respectively connected to the first fixing part 411 and the second fixing part 455 and fixed with screws. The connection method using screws and fixing parts 411 and 455 facilitates the connection and replacement of the heating wire 35. It is understood that the fixing method of the heating wire 35 is not limited to this. The base 41 allows the air intake pipe 43, the guide boss 45, and the heating wire 35 to be tightly connected together with a single component, resulting in a compact structure that allows for a smaller, more portable smoke generator 100.

[0032] Furthermore, the fixing seat 47 completely fits against the guide boss 45, thereby limiting the position of the guide boss 45. It can be understood that the fixing seat 47 can be omitted, and the guide boss 45 can be directly fixed to the base 41.

[0033] Furthermore, the inner diameter of the air inlet pipe 43 should not be less than the diameter of the air outlet 451, so as to reduce the probability of e-liquid flowing into the air inlet pipe 43 while ensuring the airflow velocity of the air outlet 451.

[0034] Furthermore, in some embodiments, the air intake assembly 40 also includes an air supply component (not shown), which is connected to the end of the air intake assembly 40 away from the heating wire 35, i.e., connected to the bottom end of the air intake pipe 43. By supplying air to the air intake pipe 43 with the air supply component, the airflow velocity within the air intake pipe 43 is increased, providing an upward force on the e-liquid, reducing the probability of e-liquid droplets falling into the air intake pipe 43, and simultaneously accelerating the exhaust of smoke from the smoke generator.

[0035] Please see Figure 5 The upper cover 10 is a circular cover with a central portion extending to form a smoke outlet 13, which connects to the first cavity 31. The upper cover 10 has at least one oil inlet 15 surrounding the smoke outlet 13, which connects to the second cavity 331. The upper cover 10 also includes a silicone plug 11 for sealing the oil inlet 15.

[0036] Please see Figure 2The atomizing chamber 33 is shaped like an inverted cover, meaning the upper opening is smaller than the lower opening. The smaller opening of the atomizing chamber 33 is connected to the lower end face of the upper cover 10 and communicates with the smoke outlet 13, while the larger opening is connected to the base 41. The atomizing chamber 33 divides the interior of the shell 30 into a first cavity 31 and a second cavity 331. The first cavity 31 and the second cavity 331 are interconnected. E-liquid is injected into the first cavity 31 through the filling port 15, and then flows into the second cavity 331 through the first cavity 31. The atomizing chamber 33 allows heat to accumulate in the second cavity 331, reducing heat loss and improving the atomization effect. It is understood that the atomizing chamber 33 is preferably made of heat-insulating material to prevent heat from being transferred to the first cavity 31 and reducing the atomization effect.

[0037] Please see Figure 6 The base 41 is a circular base with at least one connection hole 413. The connection hole 413 connects the first cavity 31 and the second cavity 331, and the e-liquid enters the second cavity 331 through the connection hole 413 for atomization.

[0038] Please see Figure 2 The bottom cover 50 is a circular cover, and a connector 51 is provided at its bottom for connecting with the air supply component or control component, etc.

[0039] The housing 30 is an annular housing, preferably made of a transparent material, so that the user can see the amount of e-liquid in the first cavity 31 through the housing 30 and replenish it in time.

[0040] Please see Figure 7 To improve the sealing of the connection between the upper cover 10, the housing 30, and the bottom cover 50, a first sealing strip 17 is provided at the connection between the upper cover 10 and the housing 30, and a second sealing strip 53 is provided at the connection between the bottom cover 50 and the housing 30. In this embodiment, the first sealing strip 17 is a circular rubber ring, and the second sealing strip 53 is a stepped boss-shaped structure. The first sealing strip 17 and the second sealing strip 53 are respectively tightly fitted to the upper and lower ends of the housing 30, and are also tightly fitted to the outer peripheral walls of the upper cover 10 and the bottom cover 50 to prevent e-liquid leakage.

[0041] Furthermore, in order to accelerate the exhaust of smoke from the atomizing chamber 33, the smoke generating device 100 provided in this application can be further connected to a smoke extraction device (not shown), which can be a pump or an axial fan. A third sealing strip 131 is provided on the outer wall of the smoke outlet 13 of the upper cover 10 and the outer wall of the connector. The third sealing strip 131 is used to improve the sealing performance at the connection between the smoke outlet and the smoke extraction device.

[0042] The smoke generator 100 of this invention adds a guide protrusion 45 above the air inlet pipe, and a guide portion 453 is provided on the guide protrusion 45 instead of the air inlet pipe 43. The air inlet pipe 43 does not need to protrude from the guide protrusion, and the guide portion 453 of the guide protrusion 45 is wider, which greatly improves the oil guiding effect and reduces the probability of e-liquid entering the air inlet pipe 43.

[0043] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
