Description

Technical Field

[0002] The prior art discloses an electronic atomization device, which is generally composed of a heating element, a battery, a control circuit and other parts. The heating element is the core component of the electronic cigarette, and its characteristics determine the atomization effect and the user experience.

[0003] Cotton core heating element core is an existing heating element, most of which are metal heating wires wrapped around cotton ropes or fiber ropes. The liquid aerosol to be atomized is absorbed by both ends of the cotton rope and then transferred to the central heating wire for heating and atomization. Due to the limited area at the end of the cotton rope, the liquid adsorption and transmission efficiency are low. In addition, the cotton rope structure has poor stability, and is prone to dry burning, carbon deposition, and burnt smell after multiple thermal cycles.

[0004] Porous ceramic heating element is another widely used heating element, which consists of two parts: porous ceramic substrate and metal heating film. The porous ceramic provides liquid conduction and storage functions, and the metal heating film realizes the heating and atomization of the liquid aerosol generation matrix. However, it is difficult to accurately control the position distribution and size accuracy of the micropores in porous ceramics prepared by high-temperature sintering.

[0005] In order to solve the above problems, researchers have tried to replace the disordered porous structure with a straight microporous structure. However, straight through hole heating elements, especially thin straight through hole heating elements, are prone to noise. Summary of the invention

[0006] Based on this, it is necessary to provide an electronic atomization device and a control method and device thereof that can reduce the noise of the through-hole heating element in order to address the above-mentioned technical problems.

[0027] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] The inventors found that through-hole heaters are easier to take in air than heaters with disordered porous structures, and the process of taking in air produces a sound similar to boiling water. If low-frequency and consistent boiling continues, it will also cause vibration and noise, affecting the user experience. The through-hole heater here refers to a hole that penetrates the substrate with a basically straight center line.

[0029] like Figure 1As shown, the heating element 130 is a thin heating element (a thin heating element refers to a heating element with a thickness of less than 3 mm), including a ceramic substrate 131, a heating film 132 and an electrode 133, wherein the ceramic substrate 131 has a relative atomization surface 1311 and a liquid absorption surface 1312, and a plurality of straight micropores 1313 are arranged on the ceramic substrate 131, and the straight micropores 1313 are through holes penetrating the ceramic substrate 131, and the straight micropores 1313 connect the liquid absorption surface 1312 and the atomization surface 1311.

[0030] The through micropores 1313 are used to guide the atomized matrix from the liquid absorption surface 1312 to the atomization surface 1311. That is, the atomized matrix in the electronic atomization device flows to the liquid absorption surface 1312 of the ceramic substrate 131 through the lower liquid channel, and is guided to the atomization surface 1311 by the capillary force of the through micropores 1313; that is, the atomized matrix flows from the liquid absorption surface 1312 to the atomization surface 1311 under the action of gravity and / or capillary force, and the atomized matrix is ​​heated and atomized on the atomization surface 1311 of the heating element 130 to generate aerosol.

[0031] However, during use, the inventor found that Figure 1 The heating element 130 shown will cause problems of high noise and vibration. The matrix is ​​as follows: the electronic atomization device uses a constant power 100HZ pulse heating method for atomization. The pulse method means that it is not a continuous power output, but an output in the form of a duty cycle, which is convenient for adjusting the duty cycle to adjust the output power. For example, when the output power is 15w, if you want to achieve a constant power output of 7.5w, adjust the duty cycle to 50%. At this time, 50% of the time, the heating element 130 is heated normally, and 50% of the time, the heating element 130 is not heated. The replenishment of the atomization matrix will cause the heating film 132 in the heating element 130 to cool down during the unheated time. This pulse control method can ensure that the problem of the heating element 130 will not be too high, but the constant power pulse control method is prone to instantaneous high power. And instantaneous high power will cause the boiling phenomenon of the atomization matrix.

[0032] In order to better understand the phenomenon of explosive boiling, the phenomenon of explosive boiling is first explained: during the heating process, pulse control will lead to instantaneous high power. At this time, the high power will cause the heating element 130 to heat up quickly and heat the atomized matrix to quickly reach the boiling point. Due to the lack of a vaporization core, there is no boiling but the temperature continues to rise to form an overheated liquid. Once this overheated liquid is triggered to boil (it can be triggered by changes in the external environment, such as shaking), it will be very violent, that is, it will form a violent boiling. The vaporization core refers to something that can trigger the boiling of the liquid, such as bubbles. If a zeolite with many tiny pores is used for heating, the air in the pores will escape due to the heat to form small bubbles. These small bubbles can serve as vaporization centers, so that the solution can boil in time after the temperature reaches the boiling point, and the solution temperature will not rise again, and no overheated liquid will be generated, and there will be no violent boiling. According to the above description, it can be seen that the smoother the surface of the heating film, the easier it is to form a violent boiling phenomenon.

[0033] At the same time, the straight micropores 1313 are easier to enter the air than the porous structure. When the temperature of the liquid is much higher than the boiling point, the saturated vapor pressure of the small bubbles in the straight micropores 1313 will be higher than the external pressure. The preset bubbles will grow and expand rapidly, pushing the straight micropores 1313 to spray to the outside, that is, the liquid spray phenomenon occurs, such as Figure 2 As described above, the air entering the through micropores 1313 forms small bubbles in the holes. During the heating process, the steam in the bubbles increases and expands, and continues to increase from left to right, so that it is ejected from the through micropores 1313, driving other atomized matrices to cause liquid spraying, which will be felt as obvious vibration and noise to the user. Electronic atomization equipment generally adopts a pulse control method, so there will be periodic liquid spraying, which will cause periodic vibration and noise, affecting the suction experience.

[0034] To solve the above problems, the following embodiments are proposed.

[0035] In one embodiment, an electronic atomization device is provided, such as Figure 3 As shown, the electronic atomization device includes:

[0036] The processing module 120, the power module 110 and the heating element 130, the heating element 130 includes a ceramic substrate 131, and the ceramic substrate 131 is provided with a plurality of straight micropores 1313 penetrating the ceramic substrate 131. The straight hole heating element refers to a hole penetrating the substrate with a substantially straight center line, and the micropore refers to a hole with a pore size less than 200um. The axis of the straight micropore 1313 is perpendicular to the ceramic substrate 131, that is, the extension direction of the straight micropore 1313 is perpendicular to the ceramic substrate 131. In this embodiment, the ceramic substrate 131 is in the form of a sheet. It can be understood that the sheet is relative to the block, and the ratio of the length to the thickness of the sheet is greater than the ratio of the length to the thickness of the block; for example, a rectangular sheet. The ceramic substrate 131 can also be in the form of a flat plate, an arc, a cylinder, etc., and is specifically designed according to needs. The other structures of the electronic atomization device are arranged in coordination with the shape of the ceramic substrate 131.

[0037] As an embodiment, the power module 110 can be connected to the processing module 120 and the heating element 130 respectively, and the processing module 120 can send a control instruction to the power module 110 to control the output power and battery frequency of the power module 110. As another embodiment, the power module 110, the processing module 120 and the heating element 130 can be connected in sequence, and the processing module 120 can control the on-off between the processing module 120 and the heating element 130 by realizing its own on-off, thereby realizing the control of the battery frequency of the power module 120. The battery frequency refers to the number of times the direction of the alternating current output by the power module 110 changes within a unit time (1 second).

[0038] The power module 110 is used to provide energy to the heating element 130 and the processing module 120 respectively, so that the processing module 120 and the heating element 130 can work normally.

[0039] In the present application, the heating element 130 is a thin heating element, and the thickness of the ceramic substrate 131 of the heating element 130 ranges from 0.1 mm to 2 mm. The thickness of the ceramic substrate 131 is the distance between the liquid absorption surface 1312 and the atomization surface 1311. When the thickness of the ceramic substrate 131 is greater than 2 mm, it cannot meet the liquid supply demand, resulting in a decrease in the amount of aerosol, and the heat loss caused is large, and the cost of setting the ceramic substrate 131 is high; when the thickness of the ceramic substrate 131 is less than 0.1 mm, the strength of the ceramic substrate 131 cannot be guaranteed, which is not conducive to improving the performance of the electronic atomization device. Preferably, the thickness of the ceramic substrate 131 ranges from 0.3 mm to 0.8 mm, and the appropriate thickness can be selected according to actual needs in the specific implementation.

[0040] The pore size of the through micropores 1313 on the ceramic substrate 131 ranges from 1um to 100um. When the pore size of the through micropores 1313 is less than 1μm, the liquid supply demand cannot be met, resulting in a decrease in the amount of aerosol; when the pore size of the through micropores 1313 is greater than 100μm, the aerosol-generating matrix is ​​likely to flow out of the through micropores 1313, causing liquid leakage. Preferably, the pore size of the through micropores 1313 ranges from 10um to 50um, and a suitable pore size can be selected according to actual needs in specific implementation.

[0041] The ratio of the thickness of the ceramic substrate 131 to the aperture of the through micropores 1313 is in the range of 50:1 to 3:1, so as to improve the liquid supply capacity. When the ratio of the thickness of the ceramic substrate 131 to the aperture of the through micropores 1313 is greater than 50:1, the atomization matrix supplied by the capillary action of the through micropores 1313 is difficult to meet the atomization demand, which is not only easy to cause dry burning, but also the amount of aerosol generated by a single atomization decreases; when the ratio of the thickness of the ceramic substrate 131 to the aperture of the through micropores 1313 is less than 3:1, the aerosol generation matrix is ​​easy to flow out of the through micropores 1313, causing waste, resulting in a decrease in atomization efficiency, and then reducing the total aerosol amount. Preferably, each of the through micropore arrays is arranged on the ceramic substrate, and the ratio of the hole center distance of the through micropores to the aperture is in the range of 3:1 to 1.5:1, which can be selected according to actual needs in the specific implementation.

[0042] The thickness of the heating film 132 is 200nm-5μm; the material of the heating film 132 is one or more of aluminum or its alloy, copper or its alloy, silver or its alloy, nickel or its alloy, chromium or its alloy, platinum or its alloy, titanium or its alloy, zirconium or its alloy, palladium or its alloy, iron or its alloy, gold or its alloy, molybdenum or its alloy, niobium or its alloy, tantalum or its alloy. Preferably, the thickness of the heating film 132 is 200nm-10μm; the material of the heating film 132 is one or more of stainless steel, nickel-chromium-iron alloy, and nickel-based corrosion-resistant alloy. The heating film 132 allows the corresponding straight-through micropores 1313 to be exposed.

[0043] The processing module 120 is used to control the power module 110 to provide energy to the heating element 130 at a frequency of 20 kHz to 30 MHz when the heating element 130 is heated.

[0044] When the user draws on the electronic atomization device, the processing module 120 detects the puffing action through the airflow sensor in the electronic atomization device. As an embodiment, after detecting the puffing action, the airflow sensor sends information that the electronic atomization device is being puffed to the processing module 120, or the processing module 120 obtains the signal detected by the airflow sensor, and detects whether the electronic atomization device is being puffed according to the signal detected by the airflow sensor. As another embodiment, the user can also trigger the heating start signal / puff start signal through the physical / virtual button in the electronic atomization device, so that the processing module 120 detects that the electronic atomization device is being puffed.

[0045] After detecting that the electronic atomization device is being inhaled, the power module 110 is controlled to provide energy to the heating element 130, so that the heating element 130 is heated. In the process of controlling the power module 110 to provide energy to the heating element 130, the power module 110 is controlled to provide energy to the heating element 130 in a high-frequency manner. High frequency means that the pulse frequency of the power module 110 is greater than or equal to 20000Hz. The human ear's perception range is mostly in the frequency of 20-20kHz, and high-frequency noise is harsh, especially the sound between 2kHz and 4kHz, which makes the user most uncomfortable.

[0046] When the same heating element 130 is used and the control power module 110 is tested at different frequencies, the obtained results are shown in the following table:

[0047]

[0048]

[0049] According to the test results, after exceeding 16kHz, the noise is basically very small, so the frequency range of the power supply module 110 controlled by the present application is 20kHz to 30MHz.

[0050] In addition, since a certain degree of un-atomized atomized matrix is ​​mixed in the atomized atomized matrix (i.e., aerosol), when the user inhales, the gas mixed with the un-atomized atomized matrix and the atomized atomized matrix can be improved in terms of sweetness and other tastes. Therefore, if the frequency is too high, the situation of liquid spraying is basically eliminated, which will affect the taste. After many tests, it was found that after adopting a frequency higher than 100kHz, the taste of some atomized matrices will become lighter. Therefore, the present application preferentially controls the frequency range of the power module 110 to be 20kHz to 100kHz.

[0051] The electronic atomization device includes: a processing module, a power module and a heating element, wherein the heating element includes a ceramic substrate, and the ceramic substrate is provided with a plurality of straight-through micropores penetrating the ceramic substrate; the processing module is used to control the power module to provide energy to the heating element in a high-frequency manner when the heating element is heated. In the above manner, the present application controls the power module to provide energy in a high-frequency manner when the heating element is heated, so that the vibration frequency of the heating element exceeds the normal perception range of humans, thereby reducing the noise caused by the vibration of the heating element.

[0052] As an example, Figure 4 As shown, the heating element 130 includes a first sub-heating element 1301 and a second sub-heating element 1302, and the first sub-heating element 1301 and the second sub-heating element 1302 are both provided with a plurality of straight micropores 1313 penetrating the ceramic substrate (the straight micropores 1313 on the second sub-heating element 1302 are not shown in the figure), and the straight micropores 1313 on the first sub-heating element 1301 and the straight micropores 1313 on the second sub-heating element 1302 can be connected to facilitate the atomization matrix from the liquid absorption surface of the second sub-heating element 1302 to the atomization surface of the first sub-heating element 1301.
