Description

Technical Field

[0001] The invention relates to a power supply device of an electronic cigarette and an electronic cigarette using the power supply device. Background Art

[0002] Electronic cigarettes, also known as e-cigarettes, are mainly used to quit smoking and replace traditional cigarettes. They have a similar appearance and taste to traditional cigarettes, and even have more flavors than traditional cigarettes. They can also inhale smoke, taste and feel like traditional cigarettes. Because electronic cigarettes do not have other harmful ingredients such as tar and suspended particles in traditional cigarettes, they are gradually replacing traditional cigarettes in the market.

[0003] At the same time, in order to simulate the inhalation feeling of a real cigarette, existing electronic cigarettes usually use an airflow trigger to control the power supply device to supply power to the atomizer device. By directly connecting the induction air path of the airflow trigger with the working air path of the atomizer device or with the suction port, when the user inhales, the airflow in the induction air path is drawn out, thereby triggering the airflow trigger to supply power to the power supply device.

[0004] However, when the induction gas path is connected to the working gas path of the atomizer, the smoke liquid and condensed water in the atomizer are likely to leak into the trigger through the induction gas path, thereby causing the trigger to be contaminated and damaged. Summary of the invention

[0005] The main purpose of the present invention is to provide a power supply device for an electronic cigarette, aiming to prevent the smoke liquid from leaking into the trigger, causing the trigger to be contaminated and damaged.

[0006] To achieve the above-mentioned purpose, the power supply device proposed in the present invention includes a main body and a trigger. The main body is provided with an induction gas circuit connected to the outside world. The trigger is accommodated in the induction gas circuit, and is triggered when the trigger senses the change of air pressure in the induction gas circuit, and transmits a control signal to the electronic components inside the main body. The main body is also provided with an oil collecting tank. When the electronic cigarette is in use, the oil collecting tank is located at the lower end of the induction gas circuit along the gravity direction and is connected to the induction gas circuit.

[0007] Optionally, the intersection of the oil collecting tank and the sensing air path is located between a first position where the sensing air path is provided with a trigger and a second position where the sensing air path is connected to the outside.

[0008] Optionally, the induction gas path includes a first section connected to the outside and a second section connected to the trigger, a bend transition is arranged between the first section and the second section, and the oil collecting tank is located at the intersection of the first section and the second section.

[0009] Optionally, a bending portion is further provided at one end of the first section communicating with the outside.

[0010] Optionally, the first section and the second section are arranged in transition with an arc surface or an inclined surface, and the notch of the oil collecting groove is at least partially located directly below the bottom end of the arc surface or the inclined surface.

[0011] Optionally, a vertical oil-blocking portion is further provided at the junction of the arc surface or the inclined surface and the second section, and the oil collecting groove is at least partially arranged opposite to the oil-blocking portion.

[0012] Optionally, the second section is arranged horizontally or the second section is arranged obliquely, and an end of the second section away from the first section is higher than an end connected to the first section.

[0013] Optionally, an area enclosed by the notch of the oil collecting groove is greater than or equal to a cross-sectional area of ​​the first section facing the oil collecting groove.

[0014] Optionally, an oil suction piece is also provided in the oil collecting tank.

[0015] Optionally, the thickness of the oil absorbing member is smaller than the depth of the oil collecting groove.

[0016] The present invention also provides an electronic cigarette, including an atomizing device and a power supply device of the electronic cigarette. When the atomizing device is installed on the power supply device, it establishes an electrical connection with the power supply device. When the user inhales, the airflow in the inductive air path is drawn out to trigger the trigger, driving the power supply device to supply power to the atomizing device. The power supply device includes a main body and a trigger. The main body is provided with an inductive air path connected to the outside. The trigger is accommodated in the inductive air path, and the trigger is triggered when it senses the change of air pressure in the inductive air path, transmitting a control signal to the electronic components inside the main body. It is characterized in that the main body is also provided with an oil collecting tank, which is located at the lower end of the inductive air path along the gravity direction and is connected to the inductive air path.

[0017] The power supply device of the electronic cigarette of the technical solution of the present invention is provided with an oil collecting groove at the lower end of the induction gas path along the gravity direction, and the oil collecting groove is connected with the induction gas path. When smoke liquid or condensed water leaks along the induction gas path, it slides down and gathers in the oil collecting groove under the action of gravity, thereby effectively preventing the smoke liquid from damaging the trigger.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).

[0026] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include such features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0027] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" 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 an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The present invention provides an electronic cigarette 1000, including an atomizing device 200 and a power supply device 100 for supplying power to the atomizing device 200. In actual application, the atomizing device 200 and the power supply device 100 can be an integral and inseparable electronic cigarette 1000, or a detachably connected split electronic cigarette 1000. In this embodiment, an integral electronic cigarette 1000 is taken as an example.

[0029] The atomizing device 200 is provided with an oil storage chamber 220 and an atomizing gas circuit 210. The atomizing gas circuit 210 is provided with a heating component 230 connected to the oil circuit of the oil storage chamber 220. The atomizing gas circuit 210 is provided with an air inlet and a suction port connected to the external air circuit on the surface of the atomizing device 200. The induction gas circuit 11 is connected to the air inlet. When the user inhales, the external airflow and the airflow in the induction gas circuit 11 are both sucked into the atomizing gas circuit 210 inside the atomizing device 200. The trigger 30 triggers the power supply device 100 to supply power to the heating component 230, so that it generates heat to heat the oil adsorbed from the oil storage chamber 220, thereby gasifying the oil into smoke and mixing with the inhaled airflow to be discharged from the suction port for the user to inhale.

[0030] The power supply device 100 includes a main body 10, and a circuit board and a power supply 70 and an output electrode electrically connected to the circuit board are provided in the main body 10, the output electrode is electrically connected to the heating component 230, and the trigger 30 is electrically connected to the circuit board. It can be understood that in actual application, in order to prevent the oil from flowing arbitrarily in the main body 10, a protective cover made of plastic, silicone or metal material can be provided in the main body 10, and the inductive air path 11 is opened inside the protective cover. For ease of installation, in this embodiment, the protective cover made of silicone material is preferably provided with an inductive air path 11. The trigger 30 can adopt a common negative pressure sensor in the field, which will not be described in detail here. Then the outer peripheral surface of the trigger 30 is interference-fitted in the inductive air path 11, and the trigger area of ​​the trigger 30 is accommodated in the inductive air path 11, so that when the user inhales, the external airflow is not easy to supplement the inductive air path 11 to affect the negative pressure state, thereby causing the insensitive trigger phenomenon.

[0031] It is understandable that, in actual application, in order to prevent oil from causing contamination and damage to the circuit board and the power supply 70, the size of the protective sleeve can be designed to be larger, and an inner cavity for accommodating the battery and the circuit board can be provided in the protective sleeve to wrap the battery and the circuit board, thereby effectively preventing the leakage of smoke liquid from causing damage to the battery or the circuit board.

[0032] refer to Figure 1 to Figure 2The protective sleeve is also provided with an oil collecting groove 12. When the electronic cigarette is in use, the oil collecting groove 12 is located at the lower end of the sensing air path 11 along the gravity direction and is connected to the sensing air path 11. When smoke liquid or condensed water leaks along the sensing air path 11, it slides down and gathers in the oil collecting groove 12 under the action of gravity, effectively preventing the smoke liquid from damaging the trigger 30.

[0033] At the same time, if Figure 1 or Figure 2 As shown, in the embodiment of the present invention, in order to prevent the accumulated smoke liquid and condensed water from flowing back, an oil absorber 50 is further provided in the oil collecting tank 12 in the embodiment of the present invention. The oil absorber 50 can be made of fiber, cotton material, cloth, paper, sponge and related polymer porous materials with oil-absorbing material. The oil absorber 50 is stacked in the oil collecting tank 12 to effectively prevent the phenomenon of oil backflow.

[0034] Specifically, Figure 2 As shown, in the embodiment of the present invention, in order to prevent the amount of smoke liquid leakage per unit time from being large and the oil liquid not being absorbed by the oil absorption member 50 in time, the thickness of the oil absorption member 50 in this embodiment is less than the depth value of the oil collecting groove 12. The space between the oil absorption member 50 and the notch of the oil collecting groove 12 forms an oil collecting space 121. When the amount of smoke liquid leaking per unit time is large, it will temporarily accumulate in the oil collecting space 121 and then be absorbed by the oil absorption member 50. It is prevented that the oil absorption member 50 fills the oil collecting space 121, resulting in a large amount of smoke liquid leakage, and part of the smoke liquid is not absorbed and directly remains in the downstream of the oil collecting groove 12 of the sensing gas path 11, resulting in damage to the trigger 30.

[0035] Specifically, Figure 1 or Figure 2 As shown, in the embodiment of the present invention, the intersection of the oil collecting groove 12 and the sensing air path 11 is located between the first position where the sensing air path 11 is provided with a trigger 30 and the second position where the sensing air path 11 is connected to the external teaching, that is, located at the front end of the trigger 30 of the smoke liquid leakage path in the sensing air path 11, so that the leaked smoke liquid must first pass through the oil collecting groove 12 to be absorbed by the oil absorption member 50. This prevents the oil from damaging the trigger device.

[0036] Specifically, Figure 1 or Figure 2As shown, in the embodiment of the present invention, in this embodiment, the induction gas path 11 includes a first section 111 connected to the outside and a second section 112 connected to the trigger 30, the first section 111 is arranged vertically and the second section 112 is arranged horizontally, and the first section 111 and the second section 112 are arranged in a bend transition, and the oil collecting tank 12 is located at the intersection of the first section 111 and the second section 112. When the smoke liquid leaks from the outside from the first section 111, the smoke liquid is affected by gravity and leaks toward the lower end along the vertical first section 111. When the smoke liquid leaks to the bend where it intersects with the second section 112, it gathers and drips into the oil collecting tank 12 located at the lower end of the gravity direction under the influence of gravity. It is not easy to leak into the second section 112 arranged in a horizontal bend. Thereby effectively preventing the leaked smoke liquid from infiltrating into the trigger 30, causing damage to the trigger 30.

[0037] It can be understood that, in actual application, the second section 112 is not limited to a horizontal setting, for example, it can also be inclined, and the end of the second section 112 away from the oil collecting tank 12 is higher than the end intersecting with the oil collecting tank 12, and the trigger 30 is located at a position of the second section 112 away from the oil collecting tank 12, so that the leaked smoke liquid can easily overcome gravity and move upward to the trigger 30 position.

[0038] Specifically, Figure 2 As shown, in the embodiment of the present invention, an arc surface or a wedge-shaped surface transition is adopted between the first section 111 and the second section 112 to form an oil guiding surface 114, and the notch of the oil collecting groove 12 is at least partially located directly below the arc surface or the inclined surface, so that the leaked smoke liquid is guided by the inclined surface or the arc surface, further ensuring that the leaked smoke liquid drips into the oil collecting groove 12.

[0039] Furthermore, if Figure 2 As shown, in an embodiment of the present invention, a vertical oil-blocking portion 115 is further provided at the junction of the arc surface or the inclined surface and the second section 112. The oil-blocking portion 115 can be an oil-blocking block provided on the second section 112 or a step formed by reducing the airflow cross-section of the second section 112. The oil-blocking portion 115 has a certain barrier effect on the leaked smoke liquid, so that the smoke liquid gathers at a lower position of the arc surface or the inclined surface and then drips into the oil collecting tank 12 under the influence of gravity.

[0040] Specifically, Figure 1As shown, in the embodiment of the present invention, a bending portion 113 is further provided at the position where the first section 111 is connected to the outside world, so that the opening of the first section 111 is misaligned with the oil collecting tank 12, so as to prevent the smoke liquid or condensed water from directly dripping into the oil collecting tank 12 and causing splashing. At the same time, by providing the bending portion 113, the relatively lower side of the inner wall of the bending portion 113 forms a trajectory for the flow of the smoke liquid, so the transition section of the arc surface and the inclined surface can be correspondingly provided on the path of its trajectory, so as to ensure that the leaked smoke liquid and condensed water are guided into the oil collecting tank 12.

[0041] Furthermore, if Figure 2 As shown, in an embodiment of the present invention, the area enclosed by the notch of the oil collecting trough 12 is greater than or equal to the cross-sectional area of ​​the first section 111 facing the oil collecting trough 12, and the notch of the oil collecting trough 12 extends toward the second section 112 to ensure that the smoke liquid and condensed water leaked from the first section 111 drip into the oil collecting trough 12.

[0042] The present invention further provides an electronic cigarette 1000, which includes an atomization device 200 and a power supply device 100 for supplying power to the atomization device 200. The specific structure of the power supply device 100 refers to the above embodiment. Since the electronic cigarette 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0043] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
