Description

Technical Field

[0001] The present application relates to an electronic cigarette, and in particular to an electronic cigarette with a press-type quantitative oil supply. Background Art

[0002] There are two main types of oil supply systems for existing electronic cigarettes: automatic oil supply and manual oil supply. The automatic oil supply system relies on built-in sensors and electronic control systems to automatically adjust the oil supply by detecting the inhalation action. The advantages of this system are good user experience and no manual operation is required. The disadvantages are that the system is complex and costly. The manual oil supply system mainly relies on the user to press or rotate the oil supply control device to adjust the oil supply. The advantages of the manual oil supply system are simple structure and low cost, and users can flexibly adjust the oil supply according to personal needs. However, the existing manual oil supply system also has some significant disadvantages. For example, due to improper user operation or unreasonable design of the control device, excessive or insufficient oil supply may occur, affecting the user experience. At the same time, the manual oil supply system has poor sealing and is prone to oil leakage, resulting in a shortened service life of the equipment and inconvenience for the user.

[0003] Although the existing automatic oil supply system provides a good user experience, its complex structure and high cost make it difficult to be widely popularized in the market. Especially for users who try e-cigarettes for the first time and users with limited financial resources, the high cost of the automatic oil supply system has become a major obstacle for them to choose e-cigarettes. In addition, the automatic oil supply system relies on the electronic control module and is easily affected by the external environment (such as temperature and humidity), resulting in system failure or instability.

[0004] In summary, based on the existing technology, developing a new push-type quantitative oil supply electronic cigarette has important significance and value. 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 an electronic cigarette with a press-type quantitative oil supply, which has low cost, simple structure, can effectively prevent oil leakage and can provide precise oil supply control, ensuring that the amount of oil used each time is consistent, thereby improving the user experience.

[0006] To achieve the above-mentioned purpose, the present application discloses an electronic cigarette with a press-type quantitative oil supply, comprising an electronic cigarette body provided with a working channel, an oil storage tank located in the electronic cigarette body, a working oil tank located in the electronic cigarette body and cooperating with the oil storage tank, a press-type oil supply assembly cooperating with the oil storage tank, an atomizing core installed in the working channel, and a battery and a control board installed in the electronic cigarette body, wherein:

[0007] The working oil tank is directly / indirectly connected to the atomizer core to supply oil to the atomizer core, and the atomizer core is electrically connected to the control board;

[0008] The battery is electrically connected to the control panel; the working oil tank is directly / indirectly connected to the outside;

[0009] The working oil tank is provided with at least one oil outlet at a preset height, and the oil outlet is connected to the bottom of the fully sealed working oil tank through a pipeline / channel;

[0010] The push-type oil supply assembly is connected to the oil storage tank and pressurizes the oil storage tank when pressed to reset, thereby replenishing oil to the working oil tank;

[0011] The push-type oil supply assembly includes a plunger, a sealed cavity located in the electronic cigarette body and used to accommodate the plunger, and the plunger and the inner wall surface of the sealed cavity are slidably sealed to separate the sealed cavity into an upper oil area and a lower gas area. When the plunger moves, the volume ratio of the oil area and the gas area is adjusted;

[0012] A working hole is provided on the oil area, and the working hole is connected to the bottom of the working oil tank through another pipeline / channel;

[0013] The plunger part extends out of the sealed cavity and is connected to a pressing part which is exposed on the electronic cigarette body and has an elastic reset function. The downward movement and reset of the pressing part drive the plunger to reciprocate in the sealed cavity.

[0014] Furthermore, the atomizer core is connected and matched with the working oil tank through the oil storage cotton.

[0015] Furthermore, the maximum volume of the oil zone is smaller than the volume of the working oil tank.

[0016] Furthermore, the working oil tank is annular and located outside the working channel; the annular working oil tank is located inside the oil storage tank.

[0017] Furthermore, the upper end of the working channel is connected to the suction nozzle installed on the electronic cigarette body, and the lower end is directly / indirectly connected to the outside.

[0018] Furthermore, an inhalation sensing device electrically connected to the control main board is installed in the electronic cigarette body, and the inhalation sensing device is installed in the working channel or in an auxiliary channel connected to the working channel.

[0019] Furthermore, the working oil tank and the working channel are formed by two coaxial pipes with different diameters passing through the oil storage tank, wherein the small-diameter pipe close to the inner side forms the working channel, and the small-diameter pipe and the large-diameter pipe are spaced apart to form the working oil tank.

[0020] Furthermore, the oil storage tank is provided with an openable and closable liquid filling port with a sealing plug, and oil is manually added to the oil storage tank through the oil filling port.

[0021] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0022] 1. Oil supply stability and accuracy: The push-type oil supply assembly ensures that the oil supply can be accurately controlled every time it is pressed, avoiding the problem of too much or too little oil supply during manual adjustment. The sliding seal between the plunger and the inner wall of the sealing cavity further improves the stability of the oil supply.

[0023] 2. Anti-leakage design: By using the air pressure principle through sealing, an effective anti-leakage design is achieved. The fully enclosed oil storage tank is connected to the working oil tank through the oil outlet, reducing the risk of oil leakage. The design of the sealed cavity and the application of the air pressure principle enhance the stability and service life of the anti-leakage.

[0024] 3. Simplify operation and improve user experience: The design of the pressing part allows users to supply oil by simply pressing, which is easy to operate and improves the user experience.

[0025] 4. Enhance product competitiveness: The simple structure reduces production and maintenance costs, improves oil supply stability and user experience, makes the product more competitive in the market and attracts more users.

[0026] 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

[0035] like Figures 1 to 3 As shown, this embodiment discloses an exemplary structure of an electronic cigarette with a press-type quantitative oil supply, and its structure is as follows:

[0036] The electronic cigarette body 1 is made of high-strength ABS material, which has good durability and safety. An independent working channel 4 is designed inside to guide smoke and accommodate other components.

[0037] In this embodiment, the oil storage tank 2 is located inside the electronic cigarette body 1 and is made of transparent glass material, which is convenient for the user to observe the change of oil amount.

[0038] The working oil tank 3 and the oil storage tank 2 are additionally arranged in the electronic cigarette body 1, and the volume of the oil storage tank 2 is larger than that of the working oil tank 3, ensuring that enough electronic cigarette oil can be stored to meet long-term use.

[0039] The working oil tank 3 is provided with an oil replenishing hole 7 at a preset height, and the oil replenishing hole 7 is used as a reference to achieve oil / gas communication with the oil storage tank 2.

[0040] More specifically, the working oil tank 3 and the working channel 4 are composed of two coaxial and concentric pipes passing through the oil storage tank 2. The pipes are made of oil-resistant polymer transparent plastic material and have good corrosion resistance and sealing properties. The small-diameter pipe near the inside forms the working channel 4, and the large-diameter pipe outside cooperates with the small-diameter pipe to form the working oil tank 3.

[0041] The oil filling hole 7 of the working oil tank 3 is located in the upper middle part of the large diameter pipe, ensuring that the oil enters the working oil tank 3 smoothly from the oil storage tank 2 and ensures a stable supply of oil to the atomizing core 6. The working oil tank 3 is designed in an annular shape, and the annular structure helps to maintain uniform distribution of oil during use.

[0042] In this embodiment, the oil replenishing hole 7 is connected to the bottom of the working oil tank 3 through the channel 15, ensuring the smooth flow of oil and the full utilization of the oil in the oil storage tank 2.

[0043] In some embodiments, an oil filling port (not shown in the figure) is provided on the top of the oil storage tank 2 to facilitate the user to refuel, and is equipped with a sealing cover to prevent oil leakage.

[0044] In this embodiment, the push-type oil supply assembly 5 includes a plunger 9 and a sealed cavity 10 located in the electronic cigarette body 1 .

[0045] More specifically, the inner cavity of the sealing cavity 10 is cylindrical, and the plunger 9 slides and seals with the inner wall of the sealing cavity 10 to separate the sealing cavity 10 into an upper oil area 11 and a lower gas area 12. When the plunger 9 moves, the volume ratio of the oil area 11 and the gas area 12 changes synchronously.

[0046] More specifically, the plunger 9 contacts the inner wall of the sealing cavity 10 by means of a rubber ring / rubber member, and has high strength and wear resistance. The plunger 9 partially extends out of the sealing cavity 10 and is connected to the pressing portion 13 exposed on the electronic cigarette body 1 .

[0047] The pressing portion 13 realizes a reset function through a reset spring 14 , and drives the plunger 9 to reciprocate in the sealing cavity 10 when pressed.

[0048] The oil area 11 is connected to the oil storage tank 2 through at least one working hole 8. The working hole 8 is located at the upper part of the oil area 11 and is connected to the bottom of the oil storage tank 2 through another channel 15 to ensure smooth flow of oil / gas exchange between the oil area 11 and the oil storage tank 2.

[0049] The gas zone 12 is connected to the external space, and gas exchange with the outside is achieved through the small holes at the bottom.

[0050] In this embodiment, the atomizer core 6 is installed in the working channel 4 and is made of ceramic material or alloy material with high thermal conductivity.

[0051] For example, in some practical applications, the core of the atomizer core 6 is a porous ceramic element made by a high-temperature sintering process, which can quickly heat and evenly atomize the e-liquid.

[0052] In most applications, the atomizer core 6 is connected to the working oil tank 3 through the oil storage cotton. The oil storage cotton is made of organic cotton material and has good oil absorption and oil conduction performance, ensuring a stable supply of oil and good oil conduction performance. The atomizer core 6 is connected to the control mainboard, which is responsible for controlling the heating of the atomizer core 6.

[0053] As the working basis of the electronic cigarette, a lithium-ion battery (not shown in the figure) is also installed in the electronic cigarette body 1 to provide a stable power supply.

[0054] In this embodiment, the battery capacity is 900mAh, which can provide long-term use. The battery is connected to the control mainboard (not shown in the figure) through a wire. The control mainboard realizes inhalation detection through an inhalation sensing device located in the working channel 4 or in an auxiliary channel connected to the working channel 4. The control mainboard detects the user's inhalation action and controls the working state of the atomizer core 6. The control mainboard includes a microprocessor that can accurately control the heating time and temperature of the atomizer core 6 according to the inhalation detection signal to ensure the best atomization effect.

[0055] During the oil supply process, the user presses the external pressing part 13, the plunger 9 moves downward, the volume of the air area 12 in the sealed cavity 10 decreases, the volume of the oil area 11 increases, and the oil in the oil storage tank 2 is sucked into the oil area 11 through the working hole 8. When the pressing part 13 is reset, the plunger 9 moves upward, the volume of the air area 12 increases, the volume of the oil area 11 decreases, and the oil is pressed into the working oil tank 3.

[0056] During the atomization process, the atomizer core 6 is electrically connected to the main control board. The main control board controls the heating of the atomizer core 6 according to the inhalation detection signal. The atomizer core 6 converts the oil into smoke and delivers it to the suction nozzle through the working channel 4.

[0057] It should be understood that, since the maximum volume of the oil area 11 is smaller than the maximum volume of the working oil tank 3 , this can prevent excessive oil replenishment at a single time and overflow from the working oil tank 3 .

[0058] Based on the above structure, this embodiment has three working states according to the liquid level position of the working oil tank 3 and the amount of liquid above the liquid level, as follows.

[0059] 1. When the liquid level exceeds the oil replenishing hole 7 and the oil is flowing back to the oil storage tank 2 through the oil replenishing hole 7: the user presses the pressing part 13, and the plunger 9 moves downward. The oil area 11 sucks oil from the oil storage tank 2, and the oil storage tank 2 sucks oil from the working oil tank 3 through the oil replenishing hole 7 to compensate for the pressure. When the pressing part 13 is reset, the plunger 9 moves upward, and the oil in the oil area 11 is pressed back to the oil storage tank 2. The oil storage tank 2 is in a positive pressure state due to the increase in oil, and an equal amount of oil is squeezed into the working oil tank 3 through the channel 15, and the oil amount remains unchanged.

[0060] 2. When the liquid level exceeds the oil replenishing hole 7 and part of the oil and part of the air flow back to the oil storage tank 2 through the oil replenishing hole 7: the user presses the pressing part 13, and the plunger 9 moves downward. The oil area 11 sucks oil from the oil storage tank 2, and at the same time, the oil storage tank 2 sucks oil from the working oil tank 3 through the oil replenishing hole 7, causing the liquid level of the working oil tank 3 to drop. When it drops below the oil replenishing hole 7, the oil storage tank 2 sucks air to compensate for the pressure. Since air is lighter than oil, it enters above the liquid level of the oil storage tank 2. When the pressing part 13 is reset, the plunger 9 moves upward, and the oil in the oil area 11 is pressed back to the oil storage tank 2. The oil storage tank 2 is in a positive pressure state due to the increase in oil, and an equal amount of oil is squeezed into the working oil tank 3 through the channel 15 to replenish the oil.

[0061] 3. When the liquid level is lower than the oil replenishing hole 7: the user presses the pressing part 13, and the plunger 9 moves downward. The oil area 11 sucks oil from the oil storage tank 2, and the oil storage tank 2 sucks air from the working oil tank 3 through the oil replenishing hole 7 to compensate for the pressure. When the pressing part 13 is reset, the plunger 9 moves upward, and the oil in the oil area 11 is pressed back to the oil storage tank 2. The oil storage tank 2 is in a positive pressure state due to the increase in oil, and an equal amount of oil is squeezed into the working oil tank 3 through the channel 15 to replenish the oil.

[0062] It should be noted that the above three working states are all when there is oil in the oil storage tank 2.

[0063] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.
