Description

A non-contact electronic cigarette heating module and heater technical field

The utility model relates to the technical field of electronic cigarettes, in particular to a non-contact electronic cigarette heating module and a heater.

Background technique

Cigarettes, cigars and other smoking products generate smoke by burning tobacco during use, and the smoke generated by tobacco combustion contains many harmful substances, such as tar, etc. Long-term inhalation of these harmful substances will cause great harm to the human body. With the advancement of science and technology and people's continuous pursuit of healthy life, an electronic cigarette has emerged as a substitute for cigarettes. Among them, a typical e-cigarette solution is to release effective substances in smoking products, such as nicotine, by means of heat not burn.

Heat-not-burn electronic cigarettes mainly use the working principle of low-temperature heating to heat the smoking products to about 300°C, so as to bake out the effective components such as nicotine in the smoking products. Harmful substances such as tar are greatly reduced.

In the related art, heat-not-burn electronic cigarettes generally use a contact heating scheme to bake smoking products, for example, a sword-shaped, needle-shaped and other heating element is inserted into the interior of the smoking product for heating. However, the contact heating scheme has the defect of uneven heating, that is, the temperature of the part that is in direct contact with the heating element is high, while the temperature of the part far from the heating element decreases rapidly, so only the part of the tobacco close to the heating element can be cured. As a result, the shredded tobacco in the smoking product cannot be completely roasted, which not only results in a large waste of shredded tobacco, but also the amount of smoke is insufficient. If the temperature of the heating body is increased to improve the baking efficiency, it is easy to cause the scorched tobacco near the heating body, which will not only affect the taste, but even lead to a large increase in harmful components, affecting the health of the body.

Utility model content

This application is made based on the inventor's knowledge and research on the following issues:

Due to the defect of uneven heating in the contact heating scheme, it will inevitably lead to insufficient baking of the smoking product, which will not only result in a large waste of cut tobacco, but also an insufficient amount of smoke. For this reason, the inventor has found through a lot of research and experiments that the process of smoking itself is a process of air flow. If the temperature of the air flowing into the smoking product is relatively high, the hot air can directly play the role of baking the smoking product. , and since the hot air can penetrate all the tobacco in the curing smoking product relatively completely and uniformly along with the smoking process, the problem of uneven heating can be effectively solved. Therefore, the overall heating effect will be better if the heating is achieved by heating the air and then using the flow of hot air during the smoking process to bake the smoking article.

Most of the heating elements of heat-not-burn electronic cigarettes (HNB) use resistance heating, so the resistance value of the heating elements must be highly consistent to ensure the same effect of each heating element on the heating-not-burn electronic cigarette. However, most of the heating elements use thick film circuit technology, which makes the resistance value deviation of the heating elements produced by screen printing relatively large (usually ±15%). at ±45°C).

In the related art, the heat-not-burn electronic cigarette mainly solves the problem of large error of the printed circuit through temperature calibration. The temperature calibration process has high cost and low efficiency, and the after-sales maintenance cost is high due to the high price of the temperature calibration instrument.

Most of the heating elements of heat-not-burn electronic cigarettes (HNB) use resistance heating, so the resistance value of the heating elements must be highly consistent to ensure that each heating element has the same effect on the heating-not-burn electronic cigarette. However, most of the heating elements use thick film circuit technology, which makes the resistance value deviation of the heating elements produced by screen printing relatively large (usually ±15%). at ±45°C).

In the related art, the heat-not-burn electronic cigarette mainly solves the problem of large error of the printed circuit through temperature calibration. The temperature calibration process has high cost and low efficiency, and the after-sales maintenance cost is high due to the high price of the temperature calibration instrument. Moreover, when the heating body needs to be replaced due to damage, the maintenance effect is poor due to the lack of professional instruments and professional support in the after-sales maintenance.

For this reason, based on years of in-depth research on non-contact electronic cigarette heaters, the applicant has found that a heating module is formed by integrating the heating element and the control circuit on the support shell. , One-to-one matching with the control circuit, to achieve precise control of a single circuit board for a single heating element, to solve the consistency of the heating module and the consistency of the heating module after after-sales replacement.

Further, the outer side walls of the first connecting piece 12 and the second connecting piece 13 are respectively provided with axial limit clamping grooves 14 to cooperate with the clamping ribs 61 provided on the heating base 6 . Specifically, the axial limit slot 14 of the first connecting piece 12 and the second connecting piece 13 is Y-shaped as a whole, and the insertion port diameter of the axial limit slot 14 is relatively large, so that the clamping rib on the heating base 6 can be heated. 61 is introduced into the axial limit slot 14, the insertion end of the axial limit slot 14 is provided with a pin hole 141 for accommodating a pin, and a pin is arranged in the pin hole 141, and the pin can be inserted into the heating base 6 card In the insertion hole 62 of the rib 61 , an inclined guide surface can be provided on the side wall of the insertion hole 62 , and the pin can be introduced into or led out of the insertion hole 62 through the inclined guide surface.

Optionally, an inner groove 15 is provided on the upper end surface of the support shell 1 , and an accommodation hole 11 for accommodating the ceramic heating element 2 is provided at the bottom of the inner groove 15 . Optionally, the support shell 1 is made of polyether ether ketone (PEEK), so that the support shell 1 has a higher melting point, the thermal deformation temperature under load is as high as 316°C, and the instantaneous use temperature can reach 300°C, so that the support shell 1 has excellent performance. excellent sliding properties, high chemical stability and hydrolysis resistance, flame retardancy. Optionally, a wire hole 16 is provided in the support shell 1 to pass a connection wire connecting the control circuit 5 and the heating circuit 22 . Optionally, the support shell 1 is provided with an accommodating groove 17 along the circumferential direction, so as to provide a sealing ring 18, so as to ensure the tightness of the assembly.

As shown in FIG. 2 to FIG. 3 , the ceramic heating element 2 is placed in the accommodating hole 11 . The ceramic heating body 2 includes a heating body 21 and a heating circuit 22, the heating body 21 is cylindrical, and the heating body 21 is provided with a porous channel 211, and the heating circuit 22 is arranged on the heating body 21 to heat the air passing through the porous channel 211. . That is to say, the heating circuit 22 performs a heating operation after being energized, thereby heating the air passing through the porous channel 211 and realizing the function of uniform heating of the air.

Optionally, the heating body 21 may be cylindrical or polygonal, such as prism, square, pentagonal, etc., which is not specifically limited in the present invention. As an embodiment, the heating body 21 is a cylinder, and the porous channel 211 is arranged in the heating body 21 in the axial direction.

In addition, the heating circuit 22 is printed on the outer surface of the heating body 21 in the form of a thick film circuit, for example, in the form of a heating wire that surrounds the outer surface of the heating body 21 and is integrated with the heating body 21 . The printing material of the heating circuit 22 includes silver, tungsten or molybdenum manganese. Specifically, the outer wall of the cylindrical honeycomb ceramic heating body 21 is heated by printing the heating silver paste thick film heating circuit 22. Since the ceramic heating body 21 adopts a porous honeycomb structure, the heating surface area of the heating body 2 can be greatly increased. Through experiments It is verified that the air can be heated to more than 300 ℃ only by heating the heating body 21 to about 380 ℃, and because the ceramic heating body 21 has a high heat capacity, a gas flow such as 50ml of air is drawn through the ceramic heating body at each port. After 2, its temperature decreased less, only decreased by 20-30℃.

When the heating circuit 22 is printed on the outer surface of the heating body 21 in the form of a thick film circuit, its heating resistance is generally a PTC thermistor, that is, the resistance increases as the temperature rises. The temperature and resistance correspond, so the temperature of the ceramic heating element 2 can be characterized by measuring the resistance value of the resistance. In this way, under the constant voltage power supply of the DC power supply, the self-compensation effect of the thick film heating circuit (the heating body cools down, the resistance value decreases, the current increases, and the power increases) can pull the heating body temperature back to the original temperature within a few seconds. , and when there is no airflow, the temperature of the heating element can remain stable without fluctuation.

Therefore, in the embodiment of the present invention, the heating body 21 adopts the honeycomb structure, so that the ceramic heating body 2 can provide sufficient heat capacity, so that the temperature effect of the airflow on the heating body 2 during the simulated smoking process is very small, so that no need Power compensation is performed, and the effect of heating air required for smoking cigarettes can be achieved by self-adjustment. In addition, the heating circuit 22 printed on the heating body 21 in the form of a thick film circuit has a clear thermal effect, the resistance will increase with the increase of temperature, and the resistance will decrease when the temperature decreases, and it can be used as a thermal sensor by itself. Therefore, No temperature sensor is required to control the heating element temperature.

Optionally, the through holes of the porous channel 211 are circular holes or polygonal holes. And, as an embodiment, the through holes of the porous channel 211 may be regularly distributed in the heating body 21 . Optionally, when the heating body 21 is a cylinder, the through holes of the porous channel 211 can be evenly distributed along the circumferential direction. Alternatively, when the through holes of the porous channel 211 are polygonal holes, they can be distributed in the cylinder in a center-symmetric manner. It can be understood that the distribution of the through holes of the porous channel 211 is not limited, as long as the heating body 21 can be defined as a porous honeycomb structure.

Optionally, the heating body 21 is made of alumina ceramics, aluminum nitride ceramics, silicon nitride ceramics, silicon carbide ceramics, beryllium oxide ceramics or zirconia ceramics. Wherein, the alumina content in the alumina ceramic is greater than 99%, and the density of the alumina ceramic is not less than 3.86 g/cm ³ .

Specifically, the ceramic heating body 2 includes a honeycomb heating body 21 made of alumina ceramics, a heating circuit 22 and a connecting wire 23 . The center of the honeycomb heating body 21 is provided with a porous channel 211. The porous channel 211 is a uniformly arranged square hole. .

To sum up, according to the ceramic heating body 2 of the embodiment of the present invention, the heating body 21 is provided with a porous channel 211, so that when the heating circuit 22 heats the air passing through the porous channel 211, the distance between the heating body 21 and the air can be increased. The contact area makes the specific surface area of the honeycomb ceramic body large, which can fully heat the air, not only the heating efficiency is high, but also because the ceramic heating body 2 has good thermal conductivity, the purpose of heating the air can be achieved faster, and due to the porous channel The existence of the structure of 211 makes the flow speed of the air limited to a certain extent, and the contact time between the hot air and the smoking product is longer when the smoking product is baked, which slows down the loss of heat and saves energy. During the suction action, the porous shape of the ceramic heating body 2 can simultaneously lock the hot air, reduce the outflow of the hot gas, and further save energy. In addition, due to the high density of the surface of the ceramic heating body 2, the adsorption of soot particles can be effectively prevented, and the effect of preventing peculiar smell can be achieved.

The cavity defined by the smoking article carrier assembly 3 is suitable for placing the smoking article, and the smoking article carrier assembly 3 separates the smoking article from the ceramic heating body 2 .

The heat pipe 31 also has a preheating function. In order to prevent direct contact between the smoking article and the ceramic heating body 2, a baffle 32 needs to be provided at the bottom of the preheating tube 31 or in the defined cavity to play a limiting role. Through repeated experiments, it is found that the baffle 32 can not only effectively isolate the smoking article from the ceramic heating element 2, but also the e-liquid precipitates generated during the smoking process of the smoking article will not condense on the ceramic heating element 2 and the baffle 32. In addition, repeated suction naturally produces a self-cleaning effect, which is not easy to retain odor, and does not require frequent cleaning, which has high use value.

When the ceramic heating body 2 is heating, the guide plate separates the ceramic heating body 2 from the smoking product, which can effectively prevent the ceramic heating body 2 from directly contacting or being too close to the smoking product, thereby preventing the smoking product from approaching the ceramic Part of the heating element 2 is heated over 320°C to cause scorching, and when the user smokes the smoking article, the hot air can quickly flow into the first cavity 331 from the hot air flow hole, which can evenly and quickly bake the smoking article.

Optionally, the baffle 32 is configured as a stepped surface extending centrally along the preheated tube wall. Specifically, as shown in FIG. ---, the number of baffles 32 can be two, and the two baffles 32 are arranged opposite to each other, so that the ceramic heating body 2 can be effectively separated from the smoking article in the cavity 33, which can effectively separate the ceramic heating body 2 from the smoking article. Effectively prevent the ceramic heating element 2 from directly contacting or being too close to the smoking article, thereby preventing the portion of the smoking article close to the ceramic heating element 2 from being heated over 320°C and scorched. In addition, when the user smokes the smoking product, the hot air can quickly circulate from the gap between the two blocking pieces 32, so that the smoking product is evenly and quickly baked.

Optionally, the sealing sleeve 4 is formed of two layers of sleeves, and the two layers of sleeves are sealed to form a sealed cavity 41. The sealed cavity 41 is set in a vacuum to reduce the heat transfer of the ceramic heating element 2 to the outside. .

The main control circuit 64 and the control circuit 5 are powered by wire welding. The five communication lines can be integrated into connectors and connected by plugging.

Optionally, the temperature control curve of the ceramic heating element 2 can be stored in the main control circuit 64, and the main control circuit 64 instructs the control circuit of the heating module 10, for example, at 350°C for 10s, at 340°C for 10s, and the heating module 10 The control circuit is responsible for implementing the temperature control strategy. Alternatively, the temperature control curve is stored on the control circuit 5 of the heating module 10 , the main control circuit 64 is only responsible for issuing commands to turn on and off the control circuit 5 of the heating module 10 , and the entire temperature control process is controlled by the heating module 10 Circuit 5 is completed independently.

To sum up, the heating module 10 is formed by integrating the heating element and the control circuit 5 on the support shell 1 to form the heating module 10. The heating module 10 measures the resistance of the heating module 10 through the instrument during production, and matches the control circuit 5 one-to-one. The precise control of a single heating element by a single circuit board is realized, and the consistency of the heating module 10 and the consistency of the heating module 10 after after-sales replacement are solved. During the long-term use of the heater, e-liquid is accumulated inside the heater, which changes the taste of smoking, so the heating element needs to be replaced. The replacement frequency is low, and the present invention can replace the heating module 10 and the heating substrate 6 separately, thereby reducing the use cost and reducing the waste of resources.
