Description

Technical Field

[0001] The present application relates to the field of electronic cigarettes, and in particular to a jet atomization electronic cigarette. Background Art

[0002] Traditional electronic cigarettes on the market currently generally have the problem of high-temperature atomization, which can easily lead to adverse conditions such as sintering, oxidation and taste changes of the e-liquid, seriously affecting the user experience. During the high-temperature atomization process, the components in the e-liquid are prone to chemical reactions, producing unpleasant tastes and harmful substances. Users often feel a tingling sensation and discomfort in the throat during use.

[0003] In order to solve the problems caused by high-temperature atomization, some industry insiders have tried to use ultrasonic atomization technology. Ultrasonic atomization atomizes the e-liquid through high-frequency vibration. In theory, it can be atomized at a lower temperature, thus avoiding the adverse effects of high temperature. However, ultrasonic atomization technology still has many shortcomings in practical applications. First, the ultrasonic atomization effect is relatively poor, and it is impossible to achieve the ideal atomization effect. It is difficult for users to obtain a uniform and sufficient amount of smoke when using it. Secondly, the efficiency of ultrasonic atomization is low. Under the same amount of smoke, ultrasonic atomization requires higher power consumption. For example, under the premise of achieving the same amount of smoke, the heating network atomization only requires 10 watts of power, while ultrasonic atomization requires 20 watts of power. This not only increases the energy consumption of electronic cigarettes, but also shortens the service life of the battery. In addition, the structure of ultrasonic atomization is large, which makes the design of electronic cigarettes bulky and not conducive to portability. Finally, it is difficult to accurately control the amount of atomization with ultrasonic atomization, resulting in unstable user experience. Most importantly, ultrasonic atomization generates room temperature mist, which has a poor taste when inhaled, and it is difficult to meet users' high-quality requirements for the taste and temperature of electronic cigarettes.

[0004] In summary, the existing technologies have obvious deficiencies in high-temperature atomization and ultrasonic atomization, and these problems need to be solved urgently to improve the overall user experience and product performance of electronic cigarettes. Utility Model Content

[0005] The purpose of the present application is to overcome at least one of the shortcomings of the prior art and to provide a jet atomization electronic cigarette, which realizes atomization with a high-pressure nozzle and adjusts the taste temperature using a heating network, thereby maintaining the original taste of the e-liquid and providing a more stable and consistent atomization effect.

[0006] To achieve the above-mentioned purpose, the present application discloses a jet atomization electronic cigarette, including an electronic cigarette body, a jet atomization component, and a heating net, wherein the electronic cigarette body has an oil tank, a working channel, a battery, and a control board connected to the battery; the heating net is installed in the working channel and close to the upper end outlet, the heating net is connected to the control board, and is powered and controlled by the control board; the jet atomization component is divided into a piston pump and a driving part, wherein the piston pump is located in the oil tank, the driving part is located outside the oil tank, and at least the driving rod of the driving part extends into the oil tank to drive the piston pump to work; the piston pump has an oil inlet close to the bottom of the oil tank and an atomization nozzle extending into the working channel and located below the heating net, and when the piston pump is working, oil is sucked from the oil tank and sprayed out from the atomization nozzle.

[0007] In some embodiments, the channel near the outlet of the atomizing nozzle is a tapered channel to pressurize the output oil.

[0008] In some embodiments, the driving part includes a motor, an eccentric wheel driven to rotate by the motor, and a driving rod connected to and cooperated with the eccentric wheel, and the reciprocating driving rod drives the piston pump to move.

[0009] In other embodiments, the driving unit is a screw motor.

[0010] In some embodiments, the upper end of the working channel is connected to the mouthpiece, and the lower end is connected to the outside.

[0011] In some embodiments, the oil tank has an openable oil filling hole.

[0012] In some embodiments, an inhalation sensor for sensing the negative pressure value of the working channel is disposed in the electronic cigarette body, and the inhalation sensor is connected to the control board.

[0013] In some embodiments, the heating temperature of the heating grid is lower than 90°C.

[0014] In some embodiments, the oil tank is a flexible structure that dynamically compensates for internal pressure changes during liquid output through deformation, thereby ensuring a stable liquid supply.

[0015] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0016] 1. No high-temperature atomization: This design uses jet atomization instead of traditional high-temperature atomization, thus avoiding the impact of high temperature on the oil. This not only reduces the damage to the components of the e-liquid, but also better preserves the original flavor and taste of the oil.

[0017] 2. Temperature control improves experience: The design of the heating net can increase the temperature of the smoke, making the smoke warmer after atomization, improving the user experience. At the same time, the precise control of the heating net can ensure the stability of the smoke temperature, further enhancing the comfort of use.

[0018] 3. Efficient oil supply: The design of the piston pump enables the electronic cigarette to efficiently absorb oil from the oil tank and spray it through the atomizing nozzle, achieving continuous and stable oil supply and ensuring a smooth and stable atomization process.

[0019] The above-listed beneficial effects are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementations will be further disclosed in the examples or other description parts of this application. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1 As shown, this embodiment discloses an exemplary structure of a jet atomization electronic cigarette. In terms of structural composition, the electronic cigarette includes an electronic cigarette body 1, a jet atomization component 2 and a heating net 3.

[0027] Specifically, the electronic cigarette body 1 is mainly composed of a shell 101, which is made of high-strength plastic or metal material, providing structural support and external protection for the electronic cigarette as a whole. An oil tank 102 and a working channel 103 are formed in the shell 101, and a battery (not shown in the figure) and a control board (not shown in the figure) are installed in the shell 101.

[0028] In this embodiment, the battery is located inside the housing 101 to provide power for the electronic cigarette. The control board is connected to the battery and is responsible for the overall operation control of the electronic cigarette, including the start-up of the spray atomization component 2 and the temperature adjustment of the heating network 3.

[0029] In most applications, the battery is a rechargeable lithium battery. Correspondingly, the electronic cigarette body 1 is provided with a charging interface connected to the control board, and the lithium battery is charged through the charging interface.

[0030] In this embodiment, the oil tank 102 is used to store oil. To meet the needs of its normal operation, the oil tank 102 is a non-fully sealed structure to facilitate the needs of oil drainage and air pressure compensation.

[0031] In some embodiments, the oil tank 102 is designed to be a fully sealed structure. To meet the needs of its normal operation, the oil tank 102 is a flexible structure that dynamically compensates for internal pressure changes during liquid output through deformation, thereby ensuring a stable liquid supply.

[0032] Specifically, as a structural requirement for realizing a non-fully sealed structure, an air inlet hole (not shown in the figure) for compensating air pressure is provided on the oil tank 102 at a position away from the liquid surface.

[0033] It is understandable that in order to prevent oil from overflowing, the air inlet is designed as a one-way air inlet, and a one-way valve-like structure is made of silicone material. This one-way valve can allow air to enter the oil tank when needed, but prevent oil from overflowing from the air inlet.

[0034] In addition, in order to increase the service life of the electronic cigarette, in some embodiments, the oil tank 102 is refillable, and the refilling structure of the oil tank 102 includes an openable oil filling hole (not shown in the figure), which is located on the top or side of the oil tank 102, so that the user can easily refill the oil. The oil filling hole is equipped with a sealing cover, which is opened for oil filling during use, and then closed after completion to ensure the sealing of the oil tank and the preservation of the oil.

[0035] The oil filling action is as follows:

[0036] When the user finds that the oil in the oil tank 102 is insufficient, he first needs to open the sealing cover of the oil filling hole. The sealing cover is usually designed as a screw cover or a flip cover, which is convenient for the user to operate.

[0037] After opening the sealing cover, the user injects the atomized oil into the oil tank 102 through the oil filling hole. During the oil filling process, there are two structures: with an air inlet hole and without an air inlet hole.

[0038] There is an air inlet structure: the air inlet for compensating air pressure allows air to enter the oil tank 102, thereby preventing oil overflow or difficulty in oil filling due to the difference in internal and external pressures caused by oil filling.

[0039] Structure without air inlet holes: The oil tank 102 dynamically compensates for the internal pressure change during liquid output through deformation, thereby ensuring a stable liquid supply.

[0040] After the oil filling is completed, the user needs to replace the sealing cover to ensure the sealing of the oil tank 102 and prevent oil leakage and contamination.

[0041] After the oil filling is completed and the sealing cover is closed, the oil in the oil tank 102 is sufficient and the electronic cigarette can return to normal working state.

[0042] In this embodiment, the working channel 103 is an important component of the electronic cigarette body, which is used to smoothly transmit the atomized smoke to the mouthpiece for the user to inhale. The working channel 103 is a circular channel with a smooth inner wall to reduce air flow resistance and oil mist condensation and turbulence during the transmission of oil mist.

[0043] It should be noted that the working channel 103 is not directly connected to the oil tank 102 .

[0044] In order to realize automatic operation, an inhalation sensor directly or indirectly connected to the working channel 103 is provided in the electronic cigarette body 1. The inhalation sensor is connected to the control board to realize inhalation sensing and provide a work start signal to the control board.

[0045] In this embodiment, the heating net 3 is installed in the working channel 103 and close to the upper end outlet, and is powered and controlled by the control panel. The heating net 3 is mainly used to increase the temperature of the smoke to ensure that the inlet temperature is suitable when inhaled.

[0046] The temperature of the heating network 3 can be adjusted by the control panel, but not exceeding 90°C to ensure the user's comfortable experience.

[0047] The heating net 3 is made of a metal material with high thermal conductivity, which can heat up quickly and evenly, and optimize the smoke temperature through precise temperature control.

[0048] It should be understood that the heating net 3 is powered and heated by the control board, and its main function is different from the heating work of the traditional atomizer core. The heating work of the traditional atomizer core is mainly to atomize the oil, while the heating work of the heating net 3 is to increase the temperature of the smoke so that the inlet temperature when the user inhales is suitable and adjustable, but not exceeding 90°C. The position design of the heating net 3 is reasonable to ensure that the heated smoke is evenly distributed and no local overheating occurs, thereby providing a more comfortable smoking experience.

[0049] In this embodiment, the spray atomization assembly 2 is composed of a piston pump 201 and a driving unit 202. The piston pump 201 is located in the oil tank 102, and its oil inlet is close to the bottom of the oil tank 102. The atomization nozzle 203 partially extends into the working channel 103 and is located below the heating network 3.

[0050] More specifically, the driving unit 202 is located outside the oil tank 102 .

[0051] In practical applications, the driving part 202 generally has two structures, one is a braided wheel structure, and the other is a screw structure.

[0052] The eccentric wheel structure includes a motor, an eccentric wheel and a driving rod. The motor drives the eccentric wheel to rotate, causing the driving rod to reciprocate, thereby driving the piston pump 201 to work.

[0053] In the screw structure, the driving part 202 is a screw motor.

[0054] It should be understood that the atomization principle of the piston pump 201 is based on the combined effect of fluid mechanics and gas dynamics. Specifically, the piston pump 201 draws the oil in the oil tank 102 into the pump body through the pressure difference generated by the reciprocating motion, and sprays it out at a high speed through the atomizing nozzle 203. When the oil passes through the atomizing nozzle 203, the oil is subjected to the shear force from the inner wall of the atomizing nozzle 203 and the airflow, and quickly splits into fine droplets. These droplets form oil mist in the working channel 103, and are then driven out of the working channel 103 by the negative pressure of the user's inhalation.

[0055] As a structural optimization, the outlet channel of the atomizing nozzle 203 is designed as a conical channel, and the output oil is pressurized through the conical structure to improve the atomization effect. The design of the conical channel helps to increase the injection speed and shear force of the oil, thereby forming more uniform and fine droplets.

[0056] Based on the above structure, the working steps of this embodiment are as follows: When the user inhales, the inhalation sensor senses the negative pressure change in the working channel 103 and transmits the signal to the control board. The control board starts the motor in the spray atomization component 2 to start working. The driving rod of the driving unit drives the piston in the piston pump 201 to move backward, a negative pressure is formed in the pump body, and the oil in the oil tank is sucked into the pump body through the oil inlet. The pump body is filled with oil and is ready for the atomization operation. The driving rod continues to reciprocate, and when the piston moves forward, the oil in the pump body is squeezed and sprayed out at a high speed through the atomization nozzle 203. During the spraying process, the oil is subjected to the shear force inside the nozzle, forming fine droplets, entering the working channel 103 and forming oil mist. The oil mist is sent out in the working channel 103 through the inhalation negative pressure and is inhaled by the user through the cigarette holder. In this process, the heating net 3 plays a role in increasing the temperature of the smoke to ensure that the inlet temperature is suitable during inhalation.

[0057] This embodiment realizes efficient atomization of the electronic cigarette through the cooperation of the spray atomization component 2 and the heating net 3, providing a good user experience.
