Description

TECHNICAL FIELD

[0001] The present application relates to the field of electronic cigarettes, and in particular to a power type clear oil electronic cigarette. BACKGROUND

[0002] In existing electronic cigarette technology, it is a common implementation to use a pumping device to send oil to the atomizing core for completion. In this design, the oil tank is usually set to a certain micro-negative pressure state to prevent oil leakage and maintain stable supply of oil. The pumping device sends oil from the oil tank to the atomizing core by mechanical force, and generates smoke after heating. However, this simple pumping method has exposed some problems in actual application, especially in the management of oil tank negative pressure and pumping efficiency.

[0003] Current clear oil electronic cigarette products need to set or reserve an air inlet or hole in the oil tank to balance the air pressure after output in order to ensure the output of oil. However, the existence of the air inlet or hole makes the oil tank have the possibility of oil leakage, and this situation often occurs in actual use. In addition, since the oil tank is directly connected with the outside, it is easy to cause oxidation of the oil, affect the taste, and even cause the oil to deteriorate. In order to avoid these problems, the oil tank is generally kept in a certain micro-negative pressure state, and a relatively stable supply is achieved by preventing oil leakage. However, during pumping, the pressure in the oil tank changes as the oil is pumped out. If these accumulated gases are not compensated or handled in time, the pressure inside the oil tank may be lower than the outside pressure, resulting in an increase in pressure difference, which affects the smoothness of pumping. This pressure difference not only can cause discontinuous or unstable pumping, but also can cause the pumping amount to be unmatched with the preset amount, thereby affecting the use experience and performance of the electronic cigarette.

[0004] In order to solve this problem, the existing technology usually uses an air inlet valve or air inlet device to compensate for the gas to balance the pressure difference between the inside and outside of the oil tank. This method can to some extent alleviate the problem of insufficient pressure in the oil tank, but its disadvantage is that the setting of the air inlet device destroys the micro-negative pressure state of the oil tank, thereby reducing the sealing performance of the oil tank, increasing the risk of oil leakage, and also making the oil more likely to oxidize and deteriorate due to contact with air. Some electronic cigarettes even use a double pump body design to control the air inlet and outlet respectively to adjust the pressure, so as to achieve more accurate control of gas and oil. Although this design is effective in function, it greatly increases the cost and complexity of the equipment, reduces the efficiency of industrial production and the market competitiveness of the product.

[0005] Therefore, the deficiencies of the prior art mainly manifest in three aspects: first, the precision and stability of the oil tank pressure control are insufficient, and the pumping is not smooth or inconsistent; second, the introduction of the air inlet device leads to the decline of the sealing performance of the oil tank, the risk of oil leakage increases, and the use effect is affected; third, the complex structure (such as double pump body) used in the prior art to improve the performance is effective in function, but greatly increases the production cost and technical complexity, which restricts the popularization of electronic cigarette products.

[0006] In order to solve the above technical problems, it is particularly important to develop a new technology that can effectively control the negative pressure in the oil tank, avoid oil oxidation and leakage, and at the same time, does not increase additional production cost. Content of the utility model

[0007] The purpose of the present application is to at least overcome one deficiency of the prior art, provide a power type clear oil electronic cigarette, which uses a double delivery peristaltic pump to realize accurate and stable oil pumping, not only meets the needs of industrial production, but also improves the use experience of consumers, and promotes the development of the electronic cigarette industry to a more efficient and intelligent direction.

[0008] To achieve the above-mentioned purpose, the present application discloses a power type clear oil electronic cigarette, which comprises a body with an oil tank, an atomizing core located in the body, and a peristaltic pump connected to the oil tank and used for supplying oil to the atomizing core. The peristaltic pump comprises a first hose and a second hose with opposite delivery directions and a pumping rotor cooperating with the first hose and the second hose. When the pumping rotor rotates, it synchronously and reversely extrudes the first hose and the second hose, realizing synchronous and reverse pumping. The first hose is connected to the oil tank and connected to the atomizing core by direct or indirect means, delivering oil from the oil tank to the atomizing core for atomization. The second hose is used for pumping equal-volume gas, liquid or gas-liquid mixture into the oil tank, balancing the pressure in the oil tank and ensuring stable pumping.

[0009] Further, one end of the first hose and the second hose is connected to the bottom end of the oil tank.

[0010] Further, a working channel is provided in the body, and the atomizing core is located in the working channel.

[0011] Further, the body is provided with an oil storage cotton core connected to the atomizing core, and the first hose is connected to the oil storage cotton core, so that the first hose indirectly cooperates with the atomizing core through the oil storage cotton core.

[0012] Further, a working oil tank is provided in the body and cooperates with the atomizing core, and the first hose and the second hose are connected to the working oil tank.

[0013] As an optional technical solution, the pumping rotor comprises a rotating disc, at least one set of extrusion wheels arranged on the rotating disc, and a motor driving the rotating disc to rotate. The set of extrusion wheels is composed of two extrusion wheels symmetrically arranged on the rotating disc. When rotating, the two extrusion wheels in the set of extrusion wheels cooperate with the first hose and the second hose respectively to realize the synchronous reverse pumping of the first hose and the second hose. Preferably, the set of extrusion wheels is provided with two sets, and four extrusion wheels are arranged on the rotating disc in a ring shape, with opposite two extrusion wheels being symmetrical.

[0014] As an optional technical solution, the pumping rotor is in an oval shape, and the long axis end of the pumping rotor cooperates with the first hose and the second hose. When rotating, the synchronous reverse pumping of the first hose and the second hose is realized.

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

[0016] 1. Precise and stable oil pumping: Through the design of the double-conveying peristaltic pump, precise and stable oil pumping can be realized, effectively solving the problem of unsmooth or inconsistent pumping in the prior art and improving the use experience of the electronic cigarette.

[0017] 2. Pressure balance in the oil tank: The second hose pumps gas or liquid back to the oil tank, ensuring the balance of the internal and external pressures in the oil tank and avoiding the problem of excessively low internal pressure in the oil tank, thereby effectively improving the continuity and stability of the pumping process.

[0018] 3. Simplified structure and reduced cost: By using the double-conveying peristaltic pump to replace the traditional air inlet valve or double-pump body design, the complexity and cost of adding additional devices are avoided, making the technology meet the needs of industrial production while reducing the manufacturing cost of the product.

[0019] 4. Improved product reliability and market competitiveness: This technology not only improves the precision and efficiency of oil pumping, but also optimizes the control of negative pressure in the oil tank, which helps to improve the overall reliability of the product and enhances the competitiveness of the electronic cigarette in the market.

[0020] 5. Promoting intelligent development: Through more efficient oil and gas control methods, this technology promotes the development of electronic cigarettes towards a more intelligent direction, with great application prospects and market potential.

[0021] The above-listed beneficial effects are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementation methods will be further disclosed in the examples or other description parts of the present application. BRIEF DESCRIPTION OF DRAWINGS

[0031] Referring to the drawings Figure 1 The following embodiments achieve efficient and stable delivery and pressure balance of the electronic cigarette liquid by setting the oil tank 3, the atomizing core 2, the oil storage cotton core and the working channel 8 in the main body 1 and using the peristaltic pump 4 for synchronous reverse pumping.

[0032] It should be particularly noted that the motor drive, the basic working principle of the peristaltic pump, the electronic control and the conventional materials or processing technology involved herein are all known to those skilled in the art or have been in the prior art, and therefore will not be disclosed in detail herein. The structure of the present embodiment and the two pumping rotor forms will be described in detail below, and the corresponding reference numerals of each component are indicated in the text.

[0033] In terms of overall structure, the power-driven clear oil electronic cigarette described in the present embodiment comprises a main body 1, and an oil tank 3, an atomizing core 2, an oil storage cotton core and a working channel 8 arranged inside the main body 1. The oil tank 3 is used for storing the electronic cigarette liquid, and the bottom thereof is connected with a first hose 5 and a second hose 6 respectively to achieve synchronous exchange between the oil liquid and the gas (or liquid): the first hose 5 delivers the oil liquid from the oil tank 3 to the atomizing core 2, and the second hose 6 returns an equal volume of gas or liquid to the oil tank 3, thereby maintaining approximately constant pressure inside the oil tank 3 and avoiding the problems of oil leakage or poor oil supply caused by pressure imbalance in the conventional design.

[0034] In one embodiment, referring to the drawings Figure 1 The atomizing core 2 is arranged in the working channel 8 and indirectly cooperates with the first hose 5 through the oil storage cotton core, so that the oil liquid pumped from the first hose 5 can be smoothly delivered to the atomizing core 2 for atomization. The oil storage cotton core is preferably made of high oil absorption materials such as polyester fiber or nylon fiber, and has a corresponding capillary structure design to effectively release the oil liquid and prevent excessive oil liquid residue during atomization.

[0035] It should be understood that the specific details of the atomizing core 2 and the oil storage cotton core in terms of materials, processes and specific structure are all known to those skilled in the art or belong to the prior art, and therefore will not be described here.

[0036] Referring to the drawings Figure 2 In another alternative embodiment, the first hose 5 can directly cooperate with the atomizing core 2 without using the transition structure of the oil storage cotton core. At this time, the atomized liquid can be delivered to the atomizing core 2 with a shorter path, reducing the absorption loss in the cotton core and improving the delivery efficiency and atomization speed to some extent. Since the oil liquid is not released or filtered by the oil storage cotton core, this design is more simple and suitable for use occasions with higher demand for continuous oil supply.

[0037] But at the same time, it also needs to be noted that in this direct feeding mode, if the oil viscosity is low or the suction frequency is high, the atomizing core 2 is prone to excessive oil supply or liquid overflow, so the peristaltic pump 4 needs to be appropriately speed-adjusted in combination with the actual working conditions and the structural characteristics of the atomizing core 2.

[0038] The technical core of the embodiment is the synchronous reverse pumping principle of the peristaltic pump 4. The peristaltic pump 4 periodically squeezes and releases the first hose 5 and the second hose 6 through the rotation and extrusion of the pumping rotor 7, thereby realizing the return of an equal volume of gas or liquid to the oil tank 3 while pumping oil, so that the oil tank 3 always maintains self-adaptive pressure balance, avoiding the dry burning and oil leakage phenomena commonly seen in traditional electronic cigarettes.

[0039] The peristaltic pump 4 includes a pumping rotor 7, a rotating disc 9, an extrusion wheel 10, and a motor, a bearing assembly, etc. matched therewith. Those skilled in the art have full knowledge of such motor-driven modes, transmission structure designs, and supporting circuits, or they have become prior art, so they will not be disclosed in detail.

[0040] In terms of specific structure, the embodiment provides two different forms of pumping rotors 7 to realize differentiated oil supply requirements and noise control:

[0041] The first rotor structure, referring to the attached Figure 3 The pumping rotor 7 of this structure usually adopts a circular or regular polygon rotating disc 9, with extrusion wheels 10 symmetrically or uniformly distributed at the circumference of the rotating disc 9. The extrusion wheels 10 rotate at high speed with the rotating disc 9 under the drive of the motor, and periodically squeeze and relax the first hose 5 and the second hose 6 in turn, thereby realizing the stable delivery of oil and gas (or liquid). The manufacturing process of this type of rotor structure is relatively mature, easy to assemble, and the regular profile of the rotating disc 9 can reduce the fatigue damage to the hose and maintain a moderate vibration and noise level when in operation, which is suitable for most conventional application scenarios. The number, size, and material of the extrusion wheels 10 can be adjusted according to the actual operating conditions of the electronic cigarette (such as oil viscosity, suction frequency, etc.). These adjustment measures are well-known in the art.

[0042] The second rotor structure, referring to the attached Figure 4In another embodiment, the pumping rotor 7 can be designed as an elliptical or irregular polygonal rotating disc 9, making the contact mode of the extrusion wheel 10 with the first hose 5 and the second hose 6 more flexible. Taking the elliptical rotor as an example, when the rotating disc 9 rotates around the minor axis, the force on the end of the major axis and the hose will change relatively obviously with the angle, and the extrusion amount of oil can be strengthened at a certain period of time, thereby providing higher instantaneous oil supply under high load or rapid pumping, and achieving better atomization effect. The irregular rotor is also based on the principle of changing the rhythm of extrusion on the hose, and can further fine-tune in terms of noise, vibration or flow accuracy. Since the manufacturing and assembly precision of the elliptical or irregular rotor is higher, the person skilled in the art can make comprehensive design in combination with factors such as hose elasticity, rotation speed and oil viscosity. These targeted optimization methods all belong to known or existing technologies, and will not be described here.

[0043] Regardless of the rotor shape, the peristaltic pump 4 supports synchronous reverse extrusion of the first hose 5 and the second hose 6: the first hose 5 delivers oil from the oil tank 3 to the atomizing core 2, and the second hose 6 returns and extracts an equal amount of gas or liquid to the oil tank 3, thereby maintaining the adaptive pressure balance inside the oil tank 3 under various working conditions. During use, the electronic control system (known technology in the art, which will not be described here) can adjust the motor output in real time according to the user's pumping frequency, ambient temperature or oil viscosity, etc., so as to achieve more accurate oil supply speed and atomization control. The oil storage cotton core connected with the first hose 5 can absorb and release oil through the pre-designed capillary structure, reduce the risk of dry burning, and maximize the use of oil. The working channel 8 tightly surrounds the atomizing core 2 to ensure that the smoke quickly converges and flows, avoiding leakage or stagnation. At the same time, through the synchronous reverse pumping design, the oil tank 3 is not prone to leakage or siphoning problems during long-term placement or transportation, and the overall use experience is safer and more stable.

[0044] From the perspective of assembly and maintenance, the above-mentioned first (circular or regular polygonal) and second (elliptical or irregular) rotor structures can be interchangeable or upgraded. For ordinary needs, a circular or regular polygonal rotor structure with simpler manufacturing process can be selected; for scenarios with high requirements for flow accuracy, noise control or atomization efficiency, an elliptical or irregular rotor structure with more targeted can be selected. The person skilled in the art can customize the rotor shape size, the number and material of the extrusion wheel 10, the hose diameter and flexibility according to different use environments and power consumption limits, which all belong to the existing technology or known technology, and will not be described here.

[0045] In summary, the embodiment achieves more efficient and stable transmission and pressure balance of oil and gas (or liquid) by setting the oil tank 3, atomizing core 2, oil storage cotton core and working channel 8 inside the main body 1, and using the peristaltic pump 4 for synchronous reverse pumping. With the two different forms (regular circle / polygon and ellipse / irregular shape) of the pumping rotor 7, the power type clear electronic cigarette can meet the needs of simple manufacturing and high precision oil supply, and has flexibility to adapt to various scenarios. With the synchronous control of the first hose 5 and the second hose 6, the self-adaptive adjustment of the pressure inside the oil tank 3 can be realized without additional pressure regulating device, which greatly reduces the risk of oil leakage and prolongs the service life. For the motor selection, control algorithm, and the design and processing technology of other parts of the peristaltic pump 4, which have not been disclosed in detail in the embodiment, they are all common sense or prior art of those skilled in the art, and will not be described. In summary, the embodiment can be widely used in various use scenarios of electronic cigarettes, effectively avoiding the traditional problems caused by pressure fluctuation or uneven oil supply, and further improving the user experience and safety.

[0046] While exemplary embodiments of the present disclosure have been described, it will be understood by those skilled in the art that various changes and modifications can be made thereto without departing from the spirit and scope of the present disclosure in its broadest form. Therefore, all changes and modifications are intended to be included within the scope of the present disclosure as defined in the appended claims. The present disclosure is defined by the appended claims and their equivalents.
