Description

Technical Field

[0001] The invention relates to an electronic cigarette atomizer, in particular to an electronic cigarette oil leakage-proof atomizer. 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, 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 component 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 part is provided at the lower end of the accommodating area. The channel contraction part 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 electronic cigarette atomizer with a strong anti-leakage effect is a technical problem to be solved urgently in the art. 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 mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected 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] The present invention provides an anti-leakage oil atomizer for an electronic cigarette, comprising: a suction nozzle 110, an oil storage component, a heating component and a shell. The suction nozzle 110 is provided with an air outlet 111. The number of the air outlets 111 can be one or more. Preferably, two air outlets 111 are symmetrically provided. The oil storage component comprises an oil storage chamber 121 and an end cover 122, wherein the oil storage chamber 121 is provided with an oil outlet 123, and the end cover and the oil outlet 123 match. The heating component is used to atomize the fluid in the oil storage chamber 121. An air flow channel is provided in the shell, and the air flow channel is connected to the air outlet 111.

[0054] Among them, the end cover 122 and the oil outlet 123 can move relatively, so that the cooperation between the oil outlet 123 and the end cover 122 is in a maintained state or a released state; in the maintained state, the oil outlet 123 is closed; in the released state, the oil outlet 123 is opened, and the fluid flows out from the oil outlet 123 and is heated and atomized by the heating component, and the atomized aerosol reaches the air outlet 111 through the air flow channel.

[0055] Furthermore, the heating component includes a heating shell, which is fixed to the end cover 122 and can move relative to the oil outlet 123 .

[0056] Furthermore, the atomizer may also include a power supply component 140, which has electrodes and an insulator, and is provided with an air inlet 141. The shell is specifically a hollow long strip structure, in which the suction nozzle 110, the oil storage component, the heating shell and the power supply component 140 are arranged from top to bottom, the heating shell and the power supply component 140 are fixed to the shell, and the inner wall of the shell and the outer wall of the heating shell and the oil storage cavity form at least a part of the air flow channel.

[0057] Specifically, the oil storage chamber 121 is fixedly connected to the suction nozzle 110, and the suction nozzle 110 and the oil storage chamber 121 move axially together, so that the cooperation between the oil outlet 123 and the end cover 122 is in a maintained state or a released state, thereby controlling the closing or opening of the oil outlet 123. The oil storage chamber 121 includes two coaxial hollow circular tubes connected by circular ring end faces. Among them, the oil outlet 123 is arranged on a hollow circular tube with a smaller diameter. The material of the oil storage chamber 121 and the end cover 122 can be plastic, as long as the hardness of the material of the oil storage chamber 121 is lower than the hardness of the material of the end cover 122, or one of the oil storage chamber 121 and the end cover 122 can be made of soft rubber material, and sealing is achieved by deformation when matched.

[0058] There are many ways to achieve the movement of the oil storage chamber 121. For example, by pulling, pressing, or rotating. Among them, the pulling method is that the user pulls up the suction nozzle 110, and the suction nozzle 110 and the oil storage chamber 121 move upward together, so that the cooperation between the oil outlet 123 and the end cover 122 is in a released state, and the oil outlet 123 is opened, that is, the oil passage is opened. At this time, if a downward pulling action is performed, the suction nozzle 110 and the oil storage chamber 121 move downward together, so that the cooperation between the oil outlet 123 and the end cover 122 is in a maintained state again, and the oil outlet 123 is closed, that is, the oil passage is closed; the pressing method refers to setting an elastic component inside the suction nozzle 110, which can specifically be a spring, a torsion spring, a spring, a pneumatic or hydraulic component. The user's pressing generates axial or radial elastic movement, thereby stimulating the relative displacement of the suction nozzle 110 and moving it together with the oil storage chamber 121; the rotation method is to screw the suction nozzle 110 open, thereby generating a relative displacement in the axial direction and moving it together with the oil storage chamber 121.

[0059] The heating shell is provided with a heating element 133 and a buffer oil storage body 134 connected to the heating element 133, and a through hole 135 is provided on the heating shell. There may be one or more through holes 135. The heating shell may also include a heating outer shell 131 and a heating inner shell 132. The heating outer shell 131 is fixed to the end face of the oil storage assembly. Preferably, matching through holes 135 are provided on both sides of the heating outer shell 131 and the heating inner shell 132. When the matching between the oil outlet 123 and the end cover 122 is in a maintained state, the end face of the heating outer shell 131 abuts against the end face of the circular ring. Among them, the heating outer shell 131 is provided with a buffer oil storage body 134, a heating element 133 and a heating inner shell 132 from top to bottom; preferably, the heating shell is movably sealed and connected to the oil outlet 123 end of the oil storage cavity 121.

[0060] The heating element 133 may be a metal heating wire, a ceramic heating element, or a metal sintering point heating element. The material of the buffer oil storage body 134 may be ceramic, fiber, or low-foaming high-temperature resistant resin. Among them, low foaming generally refers to a material with a foaming multiple of less than 2 times. High temperature resistance refers to the ability to withstand the temperature required for atomizing the oil in the electronic cigarette.

[0061] Furthermore, a leak-proof rubber plug 136 is provided in the heating inner shell 132, which has elastic deformation, and a slit is provided on the top of the leak-proof rubber plug 136 to control the opening and closing of the airflow of the air inlet 141 on the power supply component of the atomizer. Figure 4a As shown in the figure, under normal conditions, the slit is closed to prevent the oil from leaking out. Figure 4b As shown, when the suction action is performed, the leak-proof rubber plug 136 is compressed, the slit opens, the air flow is unidirectional, and the reverse flow of liquid is prevented. When the suction action stops, the leak-proof rubber plug 136 returns to its original state. This structural design can achieve self-balance of the internal air pressure. The leak-proof rubber plug 136 is only opened under pressure during suction, thereby preventing the risk of oil leakage when the atomizer is placed normally. The material of the leak-proof rubber plug 136 can be silicone or thermoplastic polyurethane elastomer.

[0062] Furthermore, a hydrophobic polymer film 113 is provided on the end surface of the oil storage chamber 121 where the oil outlet 123 is not provided, and the film is air-permeable but not water-permeable. The hydrophobic polymer film 113 may be a fiber combination or a film with micropores. Preferably, the thickness range thereof does not exceed 1 mm. The hydrophobic polymer film 113 is fixed to the suction nozzle 110 through the perforated pressing plate 112. The hydrophobic polymer film 113 may be fixed to the perforated pressing plate 112 by a compression installation method, or may be packaged inside the perforated pressing plate 112 by an integrated method.

[0063] During use, gas enters from the air inlet 141 of the lower power supply component 140, and the slit of the leak-proof rubber plug 136 opens, allowing the gas to enter the atomization area. The mist generated by the heating element 133 flows out from the through holes 135 on the sides of the heating outer shell 131 and the heating inner shell 132, flows through a part of the air flow channel to the air outlet 111 of the suction nozzle 110, and is inhaled into the mouth of the user.

[0064] During the inhalation process, the heating element 133 atomizes and consumes the tobacco oil adsorbed in the slow-moving oil storage body 134. When the oil circuit is open, the liquid in the oil storage chamber 121 flows downward and is adsorbed by the slow-moving oil storage body 134. The gas passes through the hydrophobic polymer film 113 at the upper end of the oil storage chamber 121 and enters the oil storage chamber 121, thereby maintaining the pressure balance in the oil storage chamber 121.

[0065] The airflow trajectory is non-linear, thus effectively avoiding the risk of oil droplets being brought out and inhaled into the mouth.

[0066] 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.
