Description

Technical Field

[0001] The invention relates to an atomizer, in particular to an anti-leakage oil atomizer for electronic cigarettes. Background Art

[0002] With the development of society, people's health awareness is increasing day by day. In particular, it is well known that traditional cigarettes will cause certain harm to the health of smokers themselves and others. Therefore, it is extremely urgent to create a substitute for traditional cigarettes. At present, the more common substitute for traditional cigarettes on the market is electronic cigarettes, which is essentially a device that drives the atomizer through a power source to atomize the smoke oil to form simulated cigarette smoke. Compared with traditional cigarettes, electronic cigarettes can meet the physiological needs of smokers while avoiding harmful substances such as tar, carbon monoxide, and nitrite brought by the burning of traditional cigarettes. In addition, the smoke oil forms an aerosol after atomization, which will be rapidly diluted in the air, and the low-density aerosol is difficult to be absorbed, and will not form second-hand smoke, which will endanger the health of others.

[0003] However, since the oil channel and the air flow channel of traditional electronic cigarette atomizers are interconnected, the oil is easy to leak from the air flow channel when the air flow channel needs to remain unobstructed for suction, causing contamination of the product and outer packaging; the leaked oil may also further contaminate other objects, affecting the user experience.

[0004] In order to solve the problem of oil leakage in the atomizer of the electronic cigarette, Patent Document 1 (CN205611793U) discloses a leak-proof electronic cigarette, including a mouthpiece, a cigarette rod, a liquid storage chamber and an atomizer. The cigarette rod contains a rechargeable lithium battery, and the two ends of the cigarette rod are respectively connected to the atomizer and the LED lamp by threads. The atomizer is arranged between the liquid storage chamber and the cigarette rod, wherein a heating wire is arranged inside the liquid storage chamber, and the heating wire is connected to the rechargeable lithium battery. A plurality of electronic smoke exhaust holes are arranged outside the liquid storage chamber, and a smoke exhaust cavity is arranged around the liquid storage chamber. A lampshade is arranged on the LED lamp, and a sealing ring is arranged between the cigarette rod and the atomizer.

[0005] However, although a sealing ring is provided between the cigarette rod and the atomizer of the electronic cigarette, there is still the problem of smoke oil leaking out of the electronic smoke exhaust hole.

[0006] Patent document 2 (CN205611772U) also discloses an anti-leakage structure of an electronic cigarette and an electronic cigarette. The anti-leakage structure is arranged below the heating and atomizing assembly of the electronic cigarette. The anti-leakage structure is provided with an air intake channel for connecting the internal airflow channel of the electronic cigarette and the external airflow. A accommodating area is provided in the air intake channel. A ball that can reciprocate up and down along the direction of the air intake channel is provided in the accommodating area. An air circulation space is formed between the inner side wall of the accommodating area and the ball. A channel contraction portion is provided at the lower end of the accommodating area. The channel contraction portion can clamp the ball moving downward to close the air intake channel. A stop structure is provided at the upper end of the accommodating area to prevent the ball from closing the air intake channel when moving upward. The opening and closing of the air intake channel is controlled by the lifting and lowering of the ball.

[0007] However, although the electronic cigarette anti-leakage structure and the electronic cigarette are provided with a ball that can move up and down, in order to ensure that the ball can be lifted smoothly during inhalation, its mass should not be too heavy, so there is still a risk of oil leakage.

[0008] Therefore, providing an atomizer with a strong oil leakage prevention effect is a technical problem to be solved urgently in this field. Summary of the invention

[0050] The following specific embodiments illustrate the implementation of the present invention, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this invention are limited to this implementation. On the contrary, the purpose of introducing the invention in conjunction with the implementation is to cover other options or modifications that may be extended based on the claims of the present invention. In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description.

[0051] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] In addition, the terms “upper”, “lower”, “left”, “right”, “top” and “bottom” used in the following description should not be construed as limiting the present invention.

[0053] like Figure 1-3 As shown, the present invention provides an atomizer, including a housing assembly 10, a nozzle assembly 20, a movable assembly 21, an air guide assembly 30, an atomizer assembly 40 and a liquid storage chamber 50. The nozzle assembly 20 includes at least a portion of an aerosol airflow channel, the air guide assembly 30 connects the nozzle assembly 20 and the atomizer assembly 40 for airflow circulation, and the liquid storage chamber 50 is in communication with the atomizer assembly 40. The user can control the opening and closing of the aerosol airflow channel by the displacement of the movable assembly 21.

[0054] It is understandable that when in use, the user acts on the movable component 21 to displace it, the atomizer is in the open position, the aerosol airflow channel is opened, and the user can perform a suction action; after use, the user acts to restore the movable component 21 to the initial position, the atomizer is in the closed position, and the aerosol airflow channel is closed. The present invention controls the opening and closing of the aerosol airflow channel by displacing the movable component 21, which can effectively prevent the oil leakage problem of the atomizer.

[0055] The displacement of the movable component 21 can be generated by pulling, pressing, or rotating. The pulling method is that the user pulls up the movable component 21 to generate displacement, thereby realizing the opening of the airflow channel. The pressing method refers to setting an elastic component between the movable component 21 and the mounting component of the movable component 21, which can specifically be a spring, a torsion spring, a spring, an air pressure or a hydraulic component. The user presses it to generate axial or radial elastic movement, thereby stimulating the relative displacement of the movable component 21. The rotation method is to produce a relative displacement in the axial direction by screwing the movable component 21 open.

[0056] It should be noted that, in order to more clearly describe the connection relationship between the various components of the atomizer of the present invention, the upstream end and the downstream end of each component are defined according to the flow direction of the airflow. The end through which the airflow flows first is the upstream end, and the end through which the airflow flows later is the downstream end.

[0057] like Figure 1 As shown, the housing assembly 10 is a hollow long strip structure, preferably a hollow cylinder.

[0058] The movable component 21 is movably arranged on the nozzle component 20, preferably, as Figure 1 As shown, the movable assembly 21 is movably arranged outside the downstream end of the suction nozzle assembly 20. The upstream end of the suction nozzle assembly 20 is fixedly connected to the downstream end of the housing assembly 10. Figure 4 As shown, there is at least a gap between the nozzle assembly 20 and the movable assembly 21, which serves as a part of the aerosol airflow channel for airflow to flow. The air outlet of the movable assembly 21 is arranged at the downstream end surface of the movable assembly 21.

[0059] Furthermore, the nozzle assembly 20 further includes a stopper 22. In the open position, the movable assembly 21 abuts against the stopper 22 to open the aerosol airflow channel; in the closed position, the movable assembly 21 separates from the stopper 22 to close the aerosol airflow channel. In the closed position, the upstream end of the movable assembly 21 is sealed with the upstream end of the nozzle assembly 20; the downstream end of the movable assembly 21 is interference-fitted or sealed with the downstream end of the nozzle assembly 20.

[0060] The upstream end of the nozzle assembly 20 can also be arranged inside the housing assembly 10 and fixedly connected thereto. In the closed position, the upstream end of the movable assembly 21 is sealed with the downstream end of the housing assembly 10. The movable assembly 21 and the housing assembly 10 are both made of plastic material, and the material hardness of the movable assembly 21 is lower than that of the housing assembly 10, thereby achieving a close fit between the two.

[0061] The air outlet of the suction nozzle assembly 20 includes an elastic hole arranged at the downstream end of the suction nozzle assembly 20. In the closed position, the movable assembly 21 squeezes the downstream end of the suction nozzle assembly 20, thereby closing the elastic hole.

[0062] like Figure 1 As shown, the air outlet of the suction nozzle assembly 20 also includes a ventilation opening arranged at the side of the suction nozzle assembly 20. The ventilation opening is located between the stopper component 22 and the downstream end of the suction nozzle assembly 20. The downstream end of the suction nozzle assembly 20 is not provided with an air outlet.

[0063] Preferably, if Figure 1 As shown, the upstream end of the movable assembly 21 is provided with a radial flange 23 protruding inwardly, and the downstream end thereof is provided with a radial component 24 protruding inwardly.

[0064] Specifically, when the movable component 21 moves axially upward relative to the suction nozzle assembly 20, so that the radial flange 23 of the movable component 21 abuts against the stopper component 22 of the suction nozzle assembly 20, the atomizer is in the open position and the aerosol airflow channel is opened. At this time, the airflow channel is unobstructed, which can ensure the normal operation of the suction function. When the movable component 21 moves axially downward relative to the suction nozzle assembly 20, so that the upstream end of the movable component 21 is sealed with the upstream end of the suction nozzle assembly 20, the aerosol airflow channel is closed. At this time, the radial component 24 of the movable component 21 is interference-fitted or sealed with the downstream end of the suction nozzle assembly 20, and the liquid storage chamber 50 is relatively negatively pressurized, thereby preventing the leakage of the smoke oil.

[0065] Furthermore, a horizontally placed hollow ring 25 is provided on the suction nozzle assembly 20, and air flow can enter from the upstream end of the shell assembly 10, pass through the atomization assembly 40, the air guide assembly 30 and the hollow ring 25 from bottom to top, and be discharged from the air outlet on the movable assembly 21, thereby eliminating the risk of large condensed oil droplets being inhaled into the mouth of the smoker.

[0066] The atomizing assembly 40 is disposed at the lower end of the housing assembly 10, and includes a heating component 42 and a liquid guiding component 41. The heating component 42 can be a metal heating wire, a ceramic heating element, or a metal sintering point heating element. The liquid guiding component 41 has a certain liquid absorption capacity and can be made of ceramic, a low-foaming high-temperature resistant polymer, or sintered metal powder.

[0067] The liquid storage chamber 50 is surrounded by the inner wall of the shell assembly 10 , the upstream end of the nozzle assembly 20 , the outer wall of the air guide assembly 30 and the downstream end of the atomization assembly 40 .

[0068] Furthermore, an end cap 60 is provided on the outside of the heating component 42, on which a through hole 61 is provided, and a liquid infusion interlayer 70 is provided on the outside of the end cap 60. The liquid in the liquid storage cavity 50 flows to the liquid guiding component 41 through the infusion hole 51 at the bottom thereof, the liquid infusion interlayer 70 and the through hole 61, and is then absorbed by the liquid guiding component 41. Among them, the liquid infusion interlayer 70 can store a small amount of liquid, which can be used to replace the liquid storage cotton, thereby avoiding the problem of uneven adsorption of the liquid storage cotton. Preferably, the gap range of the liquid infusion interlayer 70 is 0.2 mm to 2 mm. The liquid guiding component 41 can absorb the smoke oil, and through the buffering effect of the liquid infusion interlayer 70, the flow rate of the smoke oil flowing out of the infusion hole 51 to the liquid guiding component 41 is effectively controlled.

[0069] The heating component 42 may be disposed in the cavity of the liquid-conducting component 41, or may be pre-buried inside the liquid-conducting component 41, or may be wrapped around the outside of the liquid-conducting component 41. Figure 1 As shown, the heating component 42 is disposed in the cavity of the liquid guiding component 41, and the outer side of the heating component 42 abuts against the inner side of the cavity of the liquid guiding component 41. When the heating component 42 is in working state, it atomizes the tobacco oil absorbed by the liquid guiding component 41, and the tobacco oil moves upward after atomization, passes through the air guiding component 30, and is then inhaled into the mouth of the user at the air outlet at the downstream end of the movable component 21.

[0070] Furthermore, a leak-proof rubber plug 80 is provided between the liquid guide component 41 and the end surface of the housing assembly 10. The leak-proof rubber plug 80 has elastic deformation and its material can be silicone or thermoplastic polyurethane elastomer rubber (TPU). Its top is arc-shaped and has a slit for controlling the opening and closing of the airflow channel. Figure 5a As shown, under normal conditions, the slit is closed to prevent the condensed oil droplets from leaking out. Even if a small amount of oil is accumulated on it, the oil will be atomized when the heating element 42 is in operation and the inhalation is performed. Figure 5b As shown, when the suction action is performed, the leak-proof rubber plug 80 is compressed, the slit opens, and air flows. When the suction action stops, the leak-proof rubber plug 80 returns to its original state. This structural design can achieve self-balance of the internal air pressure. The leak-proof rubber plug 80 is only opened when it is pressed during suction, thereby preventing the risk of oil leakage when the atomizer is placed normally.

[0071] In summary, the above embodiments provided by the present invention are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
