Description

Atomizing core micropore ceramic heater and use this heater's atomizing core

Technical Field

The utility model relates to an electric heater structure, in particular to suction-type vapour fog generating device's heater for atomizing core.

The utility model discloses still relate to the suction-type vapour fog generating device atomizing core that uses above-mentioned structure heater.

Background

The inhalation type aerosol generating device used at present is a device which uses electric heating to atomize special liquid. The device can be used in the fields of inhalation therapy and the like, but is also an inhalation type steam fog generating device commonly called as 'electronic cigarette' which is most used. It includes the atomizer, and the atomizer is inside to set up heating atomization part.

As shown in figure 1, the atomization core is a relatively traditional atomization core structure, the atomization core is firstly provided with an atomization core outer cylinder 12, the atomization core outer cylinder 12 is generally cylindrical, the upper end of the atomization core outer cylinder 12 is provided with a steam fog outlet 11, the lower end of the atomization core outer cylinder is provided with an air inlet 17 and a connecting electrode 16, and the cylinder wall of the atomization core outer cylinder 12 is provided with a radial smoke inlet 15. The atomizing core outer cylinder 12 is internally provided with oil guide cotton 14 and a heating wire 13, one side of the oil guide cotton 14 is tightly attached to the inner wall of the outer cylinder 12 and communicated with a smoke liquid inlet 15, the other side of the oil guide cotton 14 is wound on the spring-shaped spiral heating wire 13, and two ends of the heating wire 13 are connected with an electrode 16. During the use, arrange this atomizing core in storing up the oil storage storehouse of storing the tobacco juice, with heater 13 and power switch-on, heater 13 produces the heat, with its adsorbed tobacco juice of leading oily cotton 14 atomizing of being close to, the tobacco juice atomizing is taken away along with the air current of breathing in, and the tobacco juice of atomizing core outside then constantly supplies into through leading oily cotton 14, realizes the purpose of continuous atomizing.

However, such conventional atomizing cores have the following drawbacks:

1. the heating wire 13 of the atomizing core with the structure is directly contacted with the oil guide cotton 14, when the heating wire 13 is heated at a high temperature for a long time, in addition to the fact that the heating wire 13 is easy to age and become brittle, the oil guide cotton 14 is denatured at a high temperature by heating for a long time, the adsorption capacity is reduced, and the atomizing effect is deteriorated.

2. Since the oil guide cotton 14 directly contacts the heating wire 13, in case the smoke liquid is exhausted and cannot be replenished in time, the temperature of the oil guide cotton 14 rises suddenly due to no smoke liquid supply, so that the oil guide cotton 14 is burnt and carbonized, and even the oil guide cotton 14 is ignited and burnt.

3. Because the adsorption capacity of the oil guide cotton 14 is generally fixed, the oil guide cotton 14 needs to be directly communicated with the oil storage bin, and after the adsorption capacity of the oil guide cotton 14 is saturated, smoke liquid seeps out and drips from the other side of the oil guide cotton 14, namely one side of the heating wire 13, and leaks out of the air inlet 17, so that the atomization core leaks oil.

4. The oil guide cotton 14 is contacted with smoke liquid of an external oil storage bin through the atomizing core outer cylinder 12, the atomizing core outer cylinder 12 is generally made of metal materials, the heat conductivity is good, and after the heating wire 13 is electrified and heated, the oil guide cotton 14 and the atomizing core outer cylinder 12 are also heated, so that the heat loss in a non-atomizing area is caused.

In order to overcome the above-mentioned drawbacks, the present inventors have devised a heater and an atomizing wick using a microporous ceramic as an oil guiding medium. The structure shown in fig. 2 is different from the structure shown in fig. 1 in that the ceramic cylinder 24 with a microporous structure is used instead of the oil guide cotton 14, and the microporous ceramic cylinder 24 has micropores, so that the functions of absorbing and transmitting the smoke liquid can be realized. The main structure of the atomizing device is a cylinder 24 made of a microporous ceramic process, a coil spring-shaped heating wire 23 is coaxially embedded on the inner wall of the microporous ceramic cylinder 24, two ends of the heating wire 23 are connected to a power supply through connecting electrode wires 26, the ceramic cylinder 24 serves as an oil guide cotton 14 when being arranged inside the atomizing core outer cylinder 22, the flowing of smoke liquid is realized through a ceramic microporous structure, and the heating atomization of the inner surface of the heating wire 23 is realized. The heater with the structure basically solves the problems of high-temperature denaturation, coking or combustion of the oil guide cotton 14, and also solves the problem of oil leakage to a certain extent due to the controllable diameter of the micropores of the microporous ceramic. Meanwhile, the problem of heat loss can be prevented to a certain extent by controlling the microporous ceramic material. However, due to the structural characteristics thereof, additional drawbacks arise:

1. the manufacturing process is complicated. The heater of the atomizing core is the most easily damaged part, so that the heater needs to be replaced frequently, and in order to reduce the use cost of the atomizing core, the heater needs to be made into a structure which is easy to replace as much as possible, so that the cost is low. It would be desirable to be able to implement mass production automation. However, the heater with such a structure needs to wind the spiral heating wire 23, then manufacture a green body of the microporous ceramic cylinder 24 on the periphery of the spiral heating wire 23, and then sinter and shape the green body, which requires a large amount of manual operation, and is difficult to realize standard production.

2. The heater of this kind of structure is when heating, and the temperature of heater 23 on the inner wall is the highest, and the tobacco juice of other positions is stored inside micropore ceramic drum 24, and the tobacco juice is atomizing suddenly on heater 23's surface when atomizing, and the atomizing of rising temperature suddenly causes the atomizing particle size inhomogeneous, can have big liquid drop to appear even, and the taste is not good when inhaling after the atomizing, and large tracts of land high temperature is atomized suddenly, also can produce the sputter sound of "squeak".

3. Because the heating wire is arranged on the inner wall of the ceramic cylinder 24, the whole inner wall is a heating area and is relatively dispersed, which is not beneficial to the rapid temperature rise of the heating area.

In view of the above, the present inventors have devised a heater for heating an end surface of a microporous ceramic cylinder, which can overcome the above-mentioned drawbacks of the oil-guiding wool, and can overcome the drawbacks of the conventional microporous ceramic heater.

Detailed Description

The present invention will be described in detail with reference to the following embodiments, but the embodiments are only for explaining the technical solutions of the present invention, and any description thereof does not affect the limitation of the protection scope.

Example 1: the present embodiment is the most typical embodiment of the present invention, and the present embodiment is a structure using a thick film printed resistor as a heating wire. As shown in fig. 3 and 4, the main body of the porous ceramic body 4 is a cylindrical porous ceramic body 4, and the porous ceramic body 4 has an axial through hole as a gas flow path 9. This micropore ceramic body 4 has an end face 8, and end face 8 is the ring shape, and the mode that adopts the thick film printing on this ring shape end face 8 is printed and is had metal or alloy thick film terminal surface heater 3, and this thick film terminal surface heater 3 is the plane convolute setting on ring shape end face 8, and the both ends of terminal surface heater 3 respectively set up a connection electrode 31, and connection electrode 31 is the metal electrode, and is pre-buried inside micropore ceramic body 1, fixed setting. The connection electrode 31 is provided with an electrode connecting wire 6 for connecting with an external power supply respectively, and the power connecting wire 6 is embedded in the microporous ceramic body 1 and integrally formed with the ceramic body 1.

As shown in fig. 5 and 6, the sectional structure of the atomizing core and the sectional structure of the heater using the microporous ceramic heater are schematically illustrated. The heater is arranged in the atomizing core outer cylinder 2, and part of the oil guide cotton 14 or the non-woven fabric is separated from the inner wall of the atomizing core, so that not only can oil be guided, but also the heat insulation effect can be achieved. The end face 8 that will set up the terminal surface heater 3 upwards sets up to satisfy the smoking air current and never set up the terminal surface 8 of heater from the terminal surface flow direction that does not set up the heater, increase atomization effect. The end surface 8 provided with the heating wire 3 is arranged upwards, so that the end is in butt joint with the vapor fog outlet 1, the other end is in butt joint with the air inlet 7, and the side wall is in butt joint with the tobacco juice inlet 5 through the oil guide cotton 14.

When the microporous ceramic body is used, the power supply is switched on, the end face heating wire 3 heats, the end face of the microporous ceramic body 1 is rapidly heated, a certain heat insulation effect can be achieved through the composition of the ceramic material, and heat is concentrated in the area of the heating wire 3 as much as possible. The temperature of the end face 8 which generates heat is rapidly raised, the atomization effect is improved, and the steam fog is generated rapidly.

In addition, different temperature gradients may be formed in the microporous ceramic body 1 along the axial direction, and as shown in fig. 6, the first temperature gradient region a is a high temperature region, the second temperature gradient region B is a medium temperature region, and the third temperature gradient region C is a low temperature region. Therefore, different atomization areas can be formed during the atomization of the smoke liquid, for example, the low-temperature area C primarily atomizes the entering smoke liquid into large-particle liquid drops, the medium-temperature area B atomizes the entering smoke liquid into medium-particle liquid drops, and the high-temperature area A can atomize into small-particle liquid drops. The large and medium particles in the low-temperature region C and the medium-temperature region B can be atomized again due to the temperature rise when flowing through the high-temperature region, and are atomized into small particle droplets, so that the atomization effect is better.

Compared with the prior art structure in fig. 2, the atomization surface is arranged on the inner wall of the cylinder 24, when smoke liquid enters along the radial direction of the cylinder, instantaneous high-temperature atomization is carried out on a large area, and the atomized liquid drops are of various sizes, wherein larger particle liquid drops exist and are difficult to atomize again. Has poor taste when being sucked. While fogging creates a large area of "squeak" splash sound.

In the manufacturing process of the heater of the embodiment, after the blank is manufactured, the electrode point 31 and the electrode wire 6 are preset, then sintering is performed, and thick film printing is performed after sintering to form the resistance end face heating wire 3. Therefore, complex manual blank making is not needed, the mechanized mass production of the assembly line can be realized, and the process cost is greatly reduced.

Example 2: the present example differs from example 1 in that the end face heater 3 is not produced by thick film printing. But the patch resistance heating wire printed by the film basically can achieve the aims of improving the atomization effect and reducing the production process cost.

Example 3: the embodiment is a relatively deteriorated embodiment, and is a manufacturing method of using a common resistance heating wire instead of printing a resistance, and laying a resistance wire after the blank is sintered, so that the production cost can be properly reduced, the atomization effect is improved, and the service life of the heating wire is prolonged compared with the prior art. However, in the production of the blank in this embodiment, the resistance wire groove needs to be formed in the end face in advance, and the resistance wire groove is not laid in a plane any more, but is laid in the groove.

Example 4: as shown in FIG. 7, the microporous ceramic heater body of the present embodiment is not a pure cylinder structure, but a profiled cylinder structure, which is composed of a sheet part 400 and a tube part 401, forming a "T" shaped structure. The letter head of the T-shaped letter is used as a sheet-shaped part 400, an end face heating wire 3 is arranged on an end face 8 of the sheet-shaped part, and the main functions of a pipe-shaped part 401 are installation positioning and air passages for air inlet.

The utility model discloses a printing or lay the resistance wire and make on the micropore ceramic body that the sintering was accomplished, therefore need not complicated manual operation and plant the heater in the blank, therefore can greatly reduced process cost, and can mass production, reduction in production cost. Meanwhile, the product with the structure can realize a certain heat insulation effect by controlling the ceramic material, so that the heating area is more concentrated, the heat loss is prevented, and the temperature of the heating area is favorably and quickly improved.
