As shown in fig. 20, the atomizing element 30 extends into the liquid guiding groove 14 of the liquid guiding element 10, where the liquid guiding groove 14 is composed of two bone positions 141 arranged at intervals on opposite sides, a plurality of bone positions 141 can be provided on the liquid guiding element 10, the bone positions 141 are a part of the liquid guiding element 10, because the size of the bone positions 141 is smaller than that of the main body portion 10 'of the atomizing liquid guiding element, the liquid in the liquid guiding element 10 is guided along the bone positions 141 downward along the main body portion 10' of the liquid guiding element, the atomizing element 30 is closely arranged on the side of the bone positions 141, and the atomizing element 30 absorbs the liquid on the surface of the bone positions 141 by the surface tension of the liquid.

As shown in fig. 21 and 22, the atomizing element 30 integrally extends into the liquid guiding groove 14 of the liquid guiding element 10, the atomizing element 30 is welded to the conductive sheet 20, the elongated portion 142 (generally flat) integrally extends below the main body portion 10' of the liquid guiding element, the liquid guiding groove 14 is located in the elongated portion 142, the atomizing element 30 integrally extends into the liquid guiding groove 14 of the elongated portion 142, the two conductive sheets 20 are respectively located at two ends of the elongated portion 142, the atomizing element 30 integrally extends into the liquid guiding groove 14 of the elongated portion 142 during assembly, and then the atomizing element 30 is welded to the two conductive sheets 20, preferably, the connection is formed between the welding portion 301 of the atomizing element 30 and the heating main body portion 302 extending into the liquid guiding groove 14 through the relatively small narrow portion 303, so as to ensure that the heating main body portion 302 heats and atomizes the liquid. In the actual design and manufacture, since the liquid guiding groove 14 penetrates through the bottom, the top, the left side and the right side of the elongated portion 142, one direction of the liquid guiding groove 14 can be blocked according to other requirements such as airflow or taste, so that the atomizing gas can escape/diffuse from the rest three directions of the liquid guiding groove and the micropores of the liquid guiding element 10, and of course, the multiple directions of the liquid guiding groove 14 can be blocked so that the atomizing gas can escape/diffuse from the rest other directions and the micropores of the liquid guiding element 10; or the liquid guiding groove can be completely blocked in four directions, and the atomizing gas can completely escape from the micropores of the liquid guiding element 10. Microporous materials or solid materials can be selected to block the through sides (mainly referring to the four directions) of the liquid guide groove 14, when solid materials are selected to block some through sides of the liquid guide groove 14, the air flow of those sides is equivalently completely blocked, and when microporous materials are selected to block some through sides of the liquid guide groove 14, the air flow of those sides which are blocked is equivalently changed. The blocking and positioning mode can be tight blocking and positioning, bonding and fixing, welding and fixing and the like.

The atomizing element 30 partially or wholly extends into the liquid guiding groove 14 of the liquid guiding element 10, so that the occurrence of a frying liquid phenomenon (generally, a frying oil phenomenon) is effectively avoided. In order to further increase the atomization area, it is also conceivable to add heat conduction insulation sheets on both sides of the atomization element 30.

As shown in fig. 7 to 8, the conductive plate 20 is fixed on the liquid guiding element 10 to form a non-detachable part (e.g. sintered), a blind hole-free liquid guiding material piece 40 is placed at the liquid guiding groove 14 of the liquid guiding element 10 or below the liquid guiding groove 14, the conductive plate 20 extends downward to form an atomizing element mounting position 21 and a power supply connecting position 22, the atomizing element 30 is fixed on the atomizing element mounting position 21 of the conductive plate 20 by spot welding, and the liquid enters the atomizing element 30 from the liquid guiding groove 14 of the liquid guiding element 10 through the blind hole-free liquid guiding material piece 40. In the third embodiment, the structure of the atomizing element 30 can be substantially the same as that of the first embodiment, so that the two extending liquid guiding portions 32 at the left and right ends of the atomizing element 30 can also extend into the liquid guiding slots 14 at the left and right ends for fixing, and can also convey the liquid into the atomizing element 30.

As shown in fig. 24 to 27, which show specific structures of the sixth and seventh embodiments of the atomizing core, the liquid guide groove 14 penetrates the liquid guide member 10 from top to bottom, the atomizing main body portion 31 (also referred to as a heat generating main body portion 302) extends into the liquid guide groove 14, and the atomizing gas cooling holes 13 are located at the side of the liquid guide groove 14.

In actual design, the liquid guiding groove 14 may be located slightly upward, as shown in fig. 26 and 27, the liquid guiding groove 14 extends upward from the bottom of the liquid guiding element 10 to penetrate the liquid guiding element 10, and the height of the liquid guiding groove 14 is greater than the height of the main body 10' of the mist liquid guiding element. Normal temperature gas is transported upwards through the atomizing gas cooling holes 13, liquid is heated into atomizing gas by the atomizing elements 30 and then transported upwards, and the atomizing gas and the normal temperature gas are mixed and cooled.

When the vent groove 11 at the top of the liquid guiding element 10 is filled with liquid and the vent groove 11 is sealed by the liquid, negative air pressure is formed in the liquid storage cavity 60 to prevent the liquid in the liquid storage cavity 60 from continuously seeping outwards, thereby achieving the purpose of preventing liquid leakage. Especially, through increasing liquid blocking bone 12, can plug up unnecessary liquid (for example tobacco tar) that oozes out, on the one hand, avoid liquid to leak outward (for example leak into air cock passageway 50 etc.), on the other hand promotes the liquid plane height around air channel 11, makes the plane of unnecessary liquid that oozes out exceed air channel 11, plugs up the air and gets into stock solution chamber 60, more does benefit to and stops the interior liquid of stock solution chamber 60 and continue toward the exosmosis, reaches the purpose of negative pressure leak protection liquid better.

And, please refer to fig. 12 to 16, which show the process of assembling the atomizer by the manufacturer, the state of the atomizer shown in fig. 16 is the state of the atomizer during storage, transportation and sale, at this time, the atomizing core 100 is not communicated with the liquid storage cavity 60, and the liquid storage cavity 60 is in a sealed state, so as to prevent the occurrence of liquid leakage. Fig. 17 to 19 show that after the terminal receives the atomizer product, the product is inverted, the liquid leakage preventing and atomizing core storing accessory 95 is firstly pulled out, then the atomizing core 100 with the power supply connecting seat 101 is taken out and is installed in the space surrounded by the lower sealing ring portion 93, the atomizing core 100 is sealed and installed, the atomizing core 100 is cut off from the extension arm 94, the liquid leakage preventing and atomizing core storing accessory 95 is removed, the state of the atomizer is as shown in fig. 10, and then the power supply and control device 70 (also referred to as a module where the lower housing is located) is assembled at the lower end of the structure shown in fig. 10, so that the atomizer product can be formed for the user to use.

As shown in fig. 23, air is introduced from a gap between the inner edge of the lower end of the lower sealing ring portion 93 and the outer edge of the lower end of the power supply connecting seat 101, the air enters the internal air passage 1012 of the power supply connecting seat 101 through the first side hole 1011 of the power supply connecting seat 101, and the air is conveyed upwards in the internal air passage 1012, then enters the bottom of the atomizing core 100 through the second side hole 1013, and then passes through the atomizing core 100 upwards. The arrows in fig. 23 indicate the direction of the gas flow, and it can be seen that the gas flow is gradually and sectionally close to the bottom of the atomizing core 100, and for the atomizing core 100, the gas inlet side can form a confluence potential, so that the gas delivery is smoother, and the sufficient atomization is facilitated.

Preferably, a check valve (e.g., a silicone check valve) is installed in the air intake direction, generally between the air inlet and the atomizing core 100, and the check valve is opened under the action of the air pressure difference during air intake and closed under the action of the elasticity of the silicone when air is not admitted, so as to prevent the liquid or condensate exploded from the atomizing core 100 from flowing out, as shown in fig. 10.

Or, air is introduced from two sides below the atomizing core 100, an accommodating cavity is arranged below the atomizing core 100 to accommodate liquid or condensate fried by the atomizing core 100, and the air inlet positions at two sides are higher than the inner bottom surface of the accommodating cavity, as shown in fig. 23.

Comparing the eighth embodiment shown in fig. 28 to 31 with the fifth embodiment shown in fig. 21, it can be seen that: the liquid guiding components 10 of the two have the same structure, but in the eighth embodiment, the atomizing component 30 is wound around the periphery of the elongated portion 142, and the atomizing component 30 is directly used to contact the elongated portion 142 to absorb liquid, so that the liquid guiding groove 14 can be arranged in the elongated portion 142 to satisfy the requirement of high atomizing efficiency and high power, and the liquid guiding groove 14 can be eliminated when the requirement of atomizing efficiency is not too high and the power is relatively low. Since the main body portion 10' of the liquid guiding element is not in direct contact with the atomizing element 30, the liquid is transmitted to the elongated portion 142 through the main body portion 10' of the liquid guiding element, which is equivalent to that for the liquid guiding element 10, only the elongated portion 142 with a small area is in contact with the atomizing element 30 and is heated and atomized, so that the main body portion 10' of the liquid guiding element can be prevented from generating peculiar smell or other harmful substances at a high temperature, and the product sanitation requirement and the user experience feeling are improved.

And, as shown in fig. 32, it shows a specific structure of the embodiment nine of the atomizing core: the bottom of the main body 10 'of the liquid guiding element is extended with an extension 142, the liquid guiding groove 14 passes through the extension 142 from top to bottom, and the extension 142 is divided into extension parts 142' located at two sides of the liquid guiding groove 14, where the extension parts 142 'at two sides are provided with the atomizing gas cooling holes 13 passing through the extension parts 142' from top to bottom, so that the atomizing gas cooling holes 13 are located at two sides of the liquid guiding groove 14. The atomizing element 30 extends into the liquid guide groove 14.

firstly, the atomization core 100 is designed by innovation, the liquid guide element 10 is provided with a vent groove 11, a liquid blocking bone 12, an atomization gas cooling hole 13 and a liquid guide groove 14, and a gap is kept between an atomization main body part 31 of the atomization element 30 and the liquid guide element 10; alternatively, the atomizing body 31 is not in direct contact with the body portion 10' of the liquid-conducting element; therefore, direct contact between the atomizing element and the liquid guiding element 10 is avoided, peculiar smell or other harmful substances generated by the liquid guiding element 10 at high temperature are avoided, and the product sanitation requirement and the user experience feeling are improved.

Two, because capillary phenomenon, the atomized liquid can be stored up in the liquid guide groove 14, atomization component 30 need not with liquid guide component 10 direct contact, just can absorb the atomized liquid in liquid guide component 10, atomization component 30 is when the heating atomization, high temperature can not appear in liquid guide component 10, do not participate in the atomizing, the shortcoming of current ceramic atomizing core 100 has been avoided completely, give full play to atomization component 30 and adopted the advantage when the porous electrothermal material of imbibition, because do not have atomization component 30 to bury in micropore ceramic the inside, the atomizing area has been increased, the bulk temperature is more balanced, atomization efficiency is higher, atomization effect is better, the taste is purer. Simultaneously because our drain component 10 does not participate in high temperature atomizing in the function, only need satisfy the drain lock liquid function, the temperature is close to ambient temperature, when atomizing gas passes through the atomizing gas cooling hole 13 of drain component 10, the storage is waited atomizing liquid in drain component 10 and can be absorbed partial heat and the large granule in the big atomizing gas, play the effect for atomizing gas cooling, avoid the user to scald the mouth, the condensate of atomizing gas at back end circulation in-process has been reduced, promote user experience and feel, realize heat and large granule cigarette liquid recovery reuse simultaneously, energy-concerving and environment-protective.

Thirdly, the atomization element 30 is not required to be buried in the microporous ceramic along with the sintering of the microporous ceramic, so that the problems of difficult positioning and complex process are solved, and the production cost is favorably controlled.

Fourth, through increasing stifled liquid bone 12, can plug up unnecessary liquid (for example tobacco tar) that oozes out, on the one hand, avoid liquid to leak outward (for example leak into air cock passageway 50 etc.), on the other hand promotes the liquid plane height around the air channel 11, makes the plane of unnecessary liquid that oozes out exceed air channel 11, plugs up the air and gets into stock solution chamber 60, more does benefit to and stops liquid in the stock solution chamber 60 and continue toward oozing, reaches the purpose of negative pressure leak protection liquid better.
