Description

Technical Field

[0001] The utility model relates to the technical field of cigarette substitutes, in particular to an electronic cigarette with precise oil supply. Background Art

[0002] An electronic atomizer is an electronic product that mimics cigarettes and can atomize tobacco oil into smoke for users to inhale. Due to the similar taste and convenience of inhalation as cigarettes, electronic atomizers have been rapidly promoted and used.

[0003] Existing electronic atomizer devices typically consist of a battery-powered main unit and an atomizer. The atomizer is the vapor-generating part of the device, storing e-liquid. High temperatures cause the e-liquid to atomize and form smoke. The main unit serves as the control center and power supply for the device. The atomizer core is typically soaked in e-liquid or wrapped in a reservoir. The e-liquid flows through the oil inlet holes in the core, where it is drawn to the heating wire by capillary force provided by the oil-conducting cotton. Power is then applied to the heating wire, causing it to produce high-temperature atomized e-liquid. Controlling the oil inlet speed is crucial throughout the lifecycle of the atomizer core. If the atomizer core inlets oil too quickly, a gurgling sound may occur during puffing, or even oil may be drawn into the mouth. If the atomizer core inlets oil too slowly, the core may dry-burn, resulting in a burnt taste and a negative vaping experience. Furthermore, the oil inlet speed of the atomizer core affects the atomization temperature, which indirectly affects the flavor.

[0004] However, the capillary force of the atomizer core oil-guiding cotton will be affected by factors such as temperature, assembly techniques, and manufacturing tolerances, which may lead to unstable oil inflow and oil locking, resulting in oil leakage and unstable taste. Utility Model Content

[0024] See also Figure 1 , is a structural diagram of a precision oil-supply electronic cigarette in one embodiment.

[0025] A precision oil supply electronic cigarette includes an atomizer 10, a battery main unit 20 and a shell 30. The atomizer 10 is the aerosol generating device of the electronic cigarette, which is used to generate heat when powered, so that the tobacco oil in the atomizer 10 forms an aerosol for the user to inhale; the battery main unit 20 is the control center and power supply center of the electronic cigarette. The battery provides electrical energy to the entire electronic cigarette circuit, so that the control center is powered to control the various components in the circuit to operate, so that the atomizer 10 can be powered and heated; the atomizer 10 is compatible with the battery main unit 20, and the atomizer 10 and the battery main unit 20 are both accommodated in the shell.

[0026] For details, please refer to Figure 2 、 Figure 4 The housing 30 is provided with a suction nozzle 32, and the atomizer 10 is connected to the suction nozzle 32. The atomizer 10 is provided with an oil storage chamber 12 and an atomizing assembly 14, and the oil storage chamber 12 is provided with an oil guide hole 122. The atomizer 10 also includes a smoke oil control mechanism 16, through which the oil storage chamber 12 and the atomizing assembly 14 are connected. The smoke oil control mechanism 16 includes an oil inlet channel 162, a control assembly 164, a power assembly 165 and an oil outlet channel 166. The oil inlet channel 162 and the oil outlet channel 166 are respectively connected to the oil storage chamber 12 and the oil guide hole 122. The power assembly 165 provides power to the control assembly 164, and the power assembly 165 is electrically connected to the battery host 20. The battery host 20 controls the connection and disconnection between the oil storage chamber 12 and the oil guide hole 122 and the oil output of the oil storage chamber 12 through the control assembly 164.

[0027] The electronic cigarette is provided with a smoke oil control mechanism 16, so that the smoke oil in the oil storage chamber 12 reaches the oil guide hole 122 after passing through the oil inlet pipe and the oil outlet pipe, and finally reaches the atomizer assembly 14, so that the atomizer assembly 14 can be atomized at high temperature to produce smoke. When the electronic cigarette is not in use, the control component 164 can be used to control the separation between the oil inlet pipe and the oil outlet pipe, so that the smoke oil in the oil storage chamber 12 cannot leak out, the oil locking is stable, and there will be no oil leakage; when the electronic cigarette needs to be used, the control component 164 can be used to control the conduction between the oil inlet pipe and the oil outlet pipe to realize the smoke oil supply, and the oil supply is stable; and in response to the different smoking taste requirements of different users, the control component 164 can also control the oil output of the oil storage chamber 12, so that different smoke oil amounts correspond to different smoke amounts, and precise control of the smoking taste can be achieved.

[0028] In this embodiment, the control assembly 164 includes a first housing, a rotor, and a roller. The rotor is fixed to the inner wall of the first housing, and the roller is fixed to one end of the rotor, driving the roller. A section of the oil inlet channel 162 and a section of the oil outlet channel 166 are both housed within the first housing and connected. The roller moves along the oil inlet channel 162 and the oil outlet channel 166 housed within the first housing. During operation, the oil in the oil storage chamber 12 enters the oil control mechanism 16 through the oil inlet channel 162 and flows out of the oil outlet channel 166 to the oil guide hole 122. Preferably, one end of the oil inlet channel 162 is connected to one end of the oil outlet channel 166, and both the oil inlet channel 162 and the oil outlet channel 166 are flexible tubes. Driven by the rotor, the roller repeatedly rotates and rolls along the oil inlet channel 162 to the oil outlet channel 166, thereby circulating the oil between the oil inlet channel 162 and the oil outlet channel 166. Moreover, when not in use, the control assembly 164 can control the separation between the oil inlet channel 162 and the oil outlet channel 166. The oil outlet speed and oil outlet amount are controlled by the speed of rotation of the rotor.

[0029] In this embodiment, the power assembly 165 is a motor. The battery main unit 20 is equipped with a main control board 22. The main control board 22 is electrically connected to the motor, which drives the rotor to rotate. The main control board 22 controls the motor's operating speed. Because the motor drives the rotor, the motor's rotational speed determines the rotor's rotational speed. To adjust the smoking experience to suit different user habits, the motor's rotational speed can be increased or decreased to achieve an adjustment. The motor's rotational speed is controlled by the main control board 22 of the battery main unit 20.

[0030] Preferably, the oil control mechanism 16 is a peristaltic pump, and the main control panel 22 is provided with at least an oil level increase control key and an oil level decrease control key. The motor increases or decreases its operating speed according to the instructions of the main control panel 22. During use, the motor speed is controlled by pressing the oil level increase control key or the oil level decrease control key. Of course, in other embodiments, a mechanical pump, diaphragm pump, piezoelectric pump, micropump, or rotary pump may also be used.

[0031] In this embodiment, the motor is set with nine gears of operating speed, V1 to V9, corresponding to the nine gears of oil pump flow, A1 to A9, of the peristaltic pump. The factory setting is that the motor operating speed is V5 and the peristaltic pump oil flow is A5. When the electronic cigarette is working, the typical flow rate of the atomizer core to consume the oil is T (mg / s), so that the median flow rate of the motor A5 = T, that is, when the user draws, the oil pump motor is defaulted to running at the median speed V5, and the corresponding oil pump flow is A5, i.e., T (mg / s). Of course, the specific gear design of the motor and the corresponding oil pump flow are not limited to 9 gears and can be reduced or increased according to demand.

[0032] See also Figure 4 In this embodiment, the e-liquid control mechanism 16 also includes a display assembly 168, which comprises a flexible circuit board 1682 and a display screen 1684. The display screen 1684 is mounted on the outer wall of the housing 30 and is electrically connected to the main control board 22. The display screen 1684 displays information such as the pump flow rate setting key, the oil level increase and decrease touch keys, the current pump flow rate level, and the battery level. The flexible circuit board 1682 has corresponding touch-sensitive areas corresponding to the touch buttons on the display screen 1684. When a finger touches a touch button on the display screen 1684, the corresponding touch-sensitive area on the flexible circuit board 1682 generates an electrical signal that is transmitted to the main control board 22, creating a similar effect to pressing a button. Users can adjust the pump motor speed and, therefore, the pump flow rate to control the inhalation experience by pressing buttons or touch keys. Specific control method: The user double-clicks the oil pump flow setting button to enter the oil pump flow setting interface. Display screen 1684 shows the current oil pump flow gear. Then, each time the oil volume increase touch button is clicked, the motor speed increases by one gear, and the corresponding oil pump flow increases by one gear and is displayed on display screen 1684. Each time the oil volume decrease touch button is clicked, the motor speed decreases by one gear, and the corresponding oil pump flow decreases by one gear and is displayed on display screen 1684. After setting, click the oil pump flow setting button to save the setting result and exit the setting interface. This is conducive to precise control of oil supply and inhalation taste, and also makes the e-cigarette more fashionable and easier to operate.

[0033] See also Figure 3In this embodiment, a one-way valve assembly 18 is further included, which is arranged at the bottom of the oil storage chamber 12. The one-way valve assembly 18 includes a second shell 182, a seat body 184, an elastic element 186 and a sealing element 188. The seat body 184 is arranged at one end of the second shell 182 close to the oil storage chamber 12, and an air inlet hole 1822 is provided at the end of the second shell 182 away from the oil storage chamber 12. The seat body 184 is provided with an air outlet hole 1842. The elastic element 186 and the sealing element 188 are arranged in the cavity surrounded by the second shell 182 and the seat body 184. The sealing element 188 is arranged at the air inlet hole 1822, and the two ends of the elastic element 186 are respectively connected to the sealing element 188 and the seat body 184. When the electronic cigarette is not in use, there is no negative pressure in the oil storage chamber 12, and the elastic element 186 contacts the sealing element 188, sealing the air inlet 1822. As the electronic cigarette is used, the oil in the oil storage chamber 12 is consumed, and negative pressure forms within the oil storage chamber 12, making it difficult to pump the oil. Under the influence of external atmospheric pressure, the sealing element 188 overcomes the pressure of the elastic element 186 and is lifted, allowing air to enter the oil storage chamber 12, eliminating the negative pressure within the oil storage chamber 12 and allowing smooth oil pumping. This cycle continues, ensuring smooth oil pumping and further ensuring stable oil supply without leaking. Of course, the provision of the base 184 not only facilitates the placement and positioning of the elastic element 186 and the sealing element 188, but also helps prevent oil leakage when there is no negative pressure in the oil storage chamber 12.

[0034] Preferably, the second housing 182 and the seat body 184 are connected by threads, snap connections or interference fits, the elastic element 186 is a spring or a spring, and the sealing element 188 is a sealing ball.

[0035] In this embodiment, the interior of the atomizer 10 is divided into an oil storage chamber 12 and an atomization channel by a partition sleeve. The atomizer assembly 14 is positioned within the atomization channel, and an oil guide hole 122 is provided in the partition sleeve. An oil reservoir may also be provided between the partition sleeve and the bottom of the oil storage chamber 12. The oil reservoir is connected to the oil storage chamber 12 via the oil control mechanism 16 and the oil guide hole 122. The oil reservoir can store a small amount of oil. On the one hand, this helps keep the atomizer assembly 14 moist with a certain amount of oil before pumping oil to prevent burning. On the other hand, it facilitates the provision of more evenly distributed oil guide holes around the periphery of the partition sleeve where the oil guide hole 122 is located, so that the atomizer assembly 14 absorbs the oil more evenly, resulting in a better atomization effect and smoking taste.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described.
