Description

Technical Field

[0001] This invention relates to the field of cigarette substitute technology, and in particular to a precision e-cigarette. Background Technology

[0002] Electronic atomizing devices are electronic products that mimic cigarettes, atomizing e-liquid into vapor for users to inhale. Due to their similar taste and ease of use to cigarettes, electronic atomizing devices have been rapidly promoted and used.

[0003] Existing electronic atomizing devices generally consist of a battery-operated main unit and an atomizer. The atomizer is the vapor-generating part of the device, containing e-liquid that vaporizes at high temperatures to form vapor. The battery-operated main unit is the control center and power supply unit of the device. The coil is usually immersed in e-liquid or wrapped in a wicking pad. E-liquid is drawn into the heating coil through the wicking pad via wicking holes, where capillary action provides the wicking pad. When electricity is applied, the heating coil generates high-temperature vaporization of the e-liquid. Throughout the coil's lifespan, controlling the wicking speed is crucial. Too fast a wicking speed will result in gurgling sounds during vaping, or even e-liquid entering the mouth; too slow a wicking speed may cause the coil to burn, producing a burnt taste and resulting in a poor vaping experience. Furthermore, the wicking speed also affects the atomization temperature, indirectly impacting the flavor.

[0004] However, the capillary force of the wicking cotton in the atomizer core can be affected by factors such as temperature, assembly method, and manufacturing tolerance, which may lead to unstable oil intake and oil retention, resulting in problems such as oil leakage and inconsistent taste. Summary of the Invention

[0005] Therefore, it is necessary to provide a precision e-cigarette that offers stable oil supply, prevents leakage, and allows for precise control of the inhalation experience, addressing the above issues.

[0006] A precision-supply electronic cigarette includes an atomizer, a battery unit, and a housing. The atomizer is adapted to the battery unit and is housed within the housing. The housing has a mouthpiece, and the atomizer communicates with the mouthpiece. The atomizer contains an oil storage chamber and an atomizing component, and the oil storage chamber has an oil guide hole. The cigarette also includes an e-liquid control mechanism, which connects the oil storage chamber and the atomizing component. The e-liquid control mechanism includes an oil inlet channel, a control component, a power component, and an oil outlet channel. The oil inlet channel and the oil outlet channel are respectively connected to the oil storage chamber and the oil guide hole.

The rotor is fixed to the inner wall of the first housing, and the roller is fixed to one end of the rotor. The rotor drives the roller to move. A section of the oil inlet channel and a section of the oil outlet channel are both housed within the first housing and are connected. The roller moves along the oil inlet channel and the oil outlet channel housed inside the first housing.

[0008] In one embodiment, the power component is a motor, the battery host is provided with a main control board, the main control board is electrically connected to the motor, the motor drives the rotor to rotate, and the main control board controls the operating speed of the motor.

[0009] In one embodiment, the e-liquid control mechanism is a peristaltic pump, and the main control board is provided with at least an e-liquid increase control key and an e-liquid decrease control key. The motor increases or decreases its operating speed according to the prompts of the main control board.

[0010] In one embodiment, the motor is equipped with nine operating speeds, V1 to V9, corresponding to nine pumping flow rates of the peristaltic pump, A1 to A9. The factory setting is that the motor operating speed is V5 and the peristaltic pump pumping flow rate is A5.

[0011] In one embodiment, the e-liquid control mechanism further includes a display component, which includes a flexible circuit board and a display screen. The display screen is disposed on the outer wall of the housing. The flexible circuit board is electrically connected to the main control board. The display screen can be set with a pump flow setting key, an e-liquid increase touch key, an e-liquid decrease touch key, and the current pump flow level.

[0012] In one embodiment, a one-way valve assembly is further included at the bottom of the oil storage chamber. The one-way valve assembly includes a second housing, a seat, an elastic element, and a sealing element. The seat is located at one end of the second housing near the oil storage chamber. An air inlet is provided at the end of the second housing away from the oil storage chamber. An air outlet is provided at the seat. The elastic element and the sealing element are located within the cavity formed by the second housing and the seat. The sealing element is located at the air inlet. The two ends of the elastic element are respectively connected to the sealing element and the seat.

[0013] In one embodiment, the second housing and the base are connected by a threaded connection, a snap-fit ​​connection, or an interference fit, the elastic element is a spring or a sheet, and the sealing element is a sealing ball.

[0014] The aforementioned precision-feed e-cigarettes offer at least the following advantages:

[0015] This e-cigarette features an e-liquid control mechanism that directs e-liquid from the reservoir through inlet and outlet pipes to the wicking hole, and finally to the atomizing component.

When needed, the control mechanism can maintain a stable e-liquid supply. Furthermore, to cater to different user preferences, the control mechanism can regulate the e-liquid output from the reservoir, allowing for precise control of the vapor production volume based on the e-liquid quantity.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Please see Figure 1 This is a schematic diagram of the structure of a precision fuel-supply electronic cigarette in one embodiment.

[0025] A precision e-cigarette includes an atomizer 10, a battery main unit 20, and a housing 30. The atomizer 10 is an aerosol generating device for the e-cigarette, used to generate heat when powered on, so that the e-liquid inside 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 e-cigarette. The battery provides power to the entire circuit of the e-cigarette, enabling the control center to power and control the operation of various components in the circuit, so that the atomizer 10 can be powered and heated. The atomizer 10 is adapted to the battery main unit 20, and both the atomizer 10 and the battery main unit 20 are housed within the housing.

[0026] For details, please refer to Figure 2 , Figure 4 The housing 30 is provided with a mouthpiece 32, and the atomizer 10 is connected to the mouthpiece 32. The atomizer 10 is provided with an oil storage chamber 12 and an atomizing component 14, and the oil storage chamber 12 is provided with an oil guide hole 122. It also includes an e-liquid control mechanism 16, which connects the oil storage chamber 12 and the atomizing component 14. The e-liquid control mechanism 16 includes an oil inlet channel 162, a control component 164, a power component 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 component 165 provides power to the control component 164, and the power component 165 is electrically connected to the battery host 20. The battery host 20 controls the opening and closing of the oil storage chamber 12 and the oil guide hole 122 and the oil output of the oil storage chamber 12 through the control component 164.

[0027] The e-cigarette uses an e-liquid control mechanism 16 to direct the e-liquid in the reservoir 12 through the inlet and outlet pipes to the wicking hole 122, and finally to the atomizing component 14. The atomizing component 14 then atomizes the e-liquid at high temperature to produce vapor. When the e-cigarette is not in use, the control mechanism 164 can control the separation between the inlet and outlet pipes, preventing the e-liquid in the reservoir 12 from leaking out and ensuring stable e-liquid supply. When the e-cigarette needs to be used, the control mechanism 164 can control the connection between the inlet and outlet pipes to ensure a stable e-liquid supply. Furthermore, to cater to different users' varying vaping preferences, the control mechanism 164 can also control the e-liquid output from the reservoir 12, allowing different amounts of e-liquid to correspond to different amounts of vapor, thus enabling precise control of the vaping experience.

[0028] In this embodiment, the control component 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. The rotor drives the roller to move. 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 are connected. The roller moves along the oil inlet channel 162 and the oil outlet channel 166 housed within the first housing. During operation, the e-liquid in the oil storage chamber 12 enters the e-liquid control mechanism 16 through the oil inlet channel 162 and flows out through the oil outlet channel 166 to the oil guide hole 122. Preferably, one end of the oil inlet channel 162 and one end of the oil outlet channel 166 are connected, and both the oil inlet channel 162 and the oil outlet channel 166 are flexible hoses. The roller rotates repeatedly along the oil inlet channel 162 to the oil outlet channel 166 as driven by the rotor, thereby allowing the e-liquid to flow through the oil inlet channel 162 and the oil outlet channel 166. Furthermore, when not in use, the control component 164 can control the separation between the oil inlet channel 162 and the oil outlet channel 166. The oil outlet speed and quantity are controlled by the rotation speed of the rotor.

[0029] In this embodiment, the power component 165 is a motor, and the battery main unit 20 is equipped with a main control board 22. The main control board 22 is electrically connected to the motor, and the motor drives the rotor to rotate. The main control board 22 controls the operating speed of the motor. Since the motor drives the rotor to rotate, the rotation speed of the motor determines the rotation speed of the rotor. When it is necessary to adjust the smoking experience according to different users' smoking habits, the rotation speed of the motor can be increased or decreased to achieve the adjustment effect. The rotation speed of the motor is controlled by the main control board 22 of the battery main unit 20.

[0030] Preferably, the e-liquid control mechanism 16 is a peristaltic pump, and the main control board 22 is equipped with at least an e-liquid level increase control button and an e-liquid level decrease control button. The motor speed is increased or decreased according to the prompts of the main control board 22. In use, the motor speed is controlled by pressing the e-liquid level increase control button or the e-liquid level decrease control button. Of course, in other embodiments, it can also be a mechanical pump, a diaphragm pump, a piezoelectric pump, a micro pump, or a rotary pump, etc.

[0031] In this embodiment, the motor has nine operating speeds, V1 to V9, corresponding to nine pumping flow rates of the peristaltic pump, A1 to A9. The factory default setting is a motor operating speed of V5 and a peristaltic pumping flow rate of A5. The typical flow rate T (mg / s) of e-liquid consumed by the atomizer coil during electronic cigarette operation ensures that the motor's median flow rate A5 = T. That is, when the user inhales, the oil pump motor operates at the median speed V5 by default, corresponding to a pumping flow rate of A5, which is T (mg / s). Of course, the specific motor speed design and corresponding pumping flow rate are not limited to nine levels and can be reduced or increased as needed.

[0032] Please see Figure 4 In this embodiment, the e-liquid control mechanism 16 further includes a display component 168, which includes a flexible circuit board 1682 and a display screen 1684. The display screen 1684 is disposed on the outer wall of the housing 30. The flexible circuit board 1682 is electrically connected to the main control board 22. The display screen 1684 can display functions such as the pump flow setting key, the e-liquid volume increase touch key, the e-liquid volume decrease touch key, the current pump flow level, and the battery level. The flexible circuit board 1682 has corresponding touch sensing areas, which correspond to the touch button positions on the display screen 1684. When a person's finger touches the touch button on the display screen 1684, the corresponding touch sensing area on the flexible circuit board 1682 generates an electrical signal and sends it to the main control board 22, producing a button-like effect. The user can adjust the speed of the e-liquid pump motor by pressing the buttons or touching the buttons, thereby adjusting the pump flow to control the vaping experience. Specific control method: Users can enter the pump flow setting interface by double-clicking the pump flow setting button. The display screen (1684) shows the current pump flow level. Each click of the "increase flow" button increases the motor speed by one level, corresponding to an increase in pump flow, which is also displayed on the 1684 screen. Conversely, each click of the "decrease flow" button decreases the motor speed by one level, also corresponding to a decrease in pump flow, which is also displayed on the 1684 screen. After setting, clicking the pump flow setting button saves the settings and exits the setting interface. This allows for precise control of the e-cigarette supply and inhalation flavor, while also making the e-cigarette more stylish and easier to operate.

[0033] Please see Figure 3In this embodiment, a one-way valve assembly 18 is also provided at the bottom of the oil storage chamber 12. The one-way valve assembly 18 includes a second housing 182, a seat 184, an elastic element 186, and a sealing element 188. The seat 184 is provided at one end of the second housing 182 near the oil storage chamber 12. An air inlet 1822 is provided at the end of the second housing 182 away from the oil storage chamber 12. An air outlet 1842 is provided at the seat 184. The elastic element 186 and the sealing element 188 are provided in the cavity formed by the second housing 182 and the seat 184. The sealing element 188 is provided at the air inlet 1822. The two ends of the elastic element 186 are respectively connected to the sealing element 188 and the seat 184. When the e-cigarette is not in use, there is no negative pressure in the oil reservoir 12, and the elastic element 186 abuts against the sealing element 188, sealing the air inlet 1822. As the e-cigarette is used, the e-liquid in the oil reservoir 12 is consumed, creating a negative pressure inside the oil reservoir 12, making it difficult to pump e-liquid. Under the action of external atmospheric pressure, the sealing element 188 overcomes the pressure of the elastic element 186 and is pushed up, allowing air to enter the oil reservoir 12, thus eliminating the negative pressure and making e-liquid pumping smooth. This cycle continues, ensuring smooth pumping and further guaranteeing the stability of the oil intake while preventing leakage. Of course, the design of the base 184 facilitates the placement and positioning of the elastic element 186 and the sealing element 188, and also helps prevent e-liquid leakage when there is no negative pressure in the oil reservoir 12.

[0034] Preferably, the second housing 182 and the base 184 are connected by threads, snap-fit, or interference fit, the elastic element 186 is a spring or sheet, and the sealing element 188 is a sealing ball.

[0035] In this embodiment, the atomizer 10 is internally divided into an oil storage chamber 12 and an atomization channel by a partition sleeve. The atomization component 14 is placed inside the atomization channel, and the oil guide hole 122 is located in the partition sleeve. An oil storage tank can also be provided between the partition sleeve and the bottom of the oil storage chamber 12. The oil storage tank and the oil storage chamber 12 are connected via the e-liquid control mechanism 16 and the oil guide hole 122. The oil storage tank can store a small amount of e-liquid, which helps to keep the atomization component 14 moist with a certain amount of e-liquid before pumping, preventing it from burning. On the other hand, it also helps to set more uniform and symmetrical oil guide holes on the outer periphery of the partition sleeve where the oil guide hole 122 is located, so that the atomization component 14 absorbs e-liquid more evenly, resulting in better atomization effect and vaping experience.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
