In some embodiments, the electrode column 15 is used for electrical connection with the positive electrode of the battery device 2 , and the base 11 is used for electrical connection with the negative electrode of the battery device 2 , thereby forming an electrical circuit. After allowing the current to come out through the positive electrode of the battery device 2, it passes through the electrode column 15 and the second electrode claw 18 in sequence, and reaches the lower end of the atomizing assembly 14, penetrates the atomizing assembly 14 and makes the atomizing assembly 14 heat up, and then reaches the atomizing assembly. 14 , and then return to the negative electrode of the battery device 2 after passing through the first electrode claw 17 , the ventilation pipe 12 and the base 11 in sequence. It can be understood that, in some embodiments, the electrode column 15 and the base 11 can also be electrically connected to the negative electrode and the positive electrode of the battery device 2 respectively, and in this case, the direction of the current is opposite to the above-mentioned direction.

As shown in FIGS. 6 and 7 , in some embodiments, the base 11 may be integrally formed with a metal material, which may include a circular base 111 , a first mounting cylinder 112 longitudinally disposed on the upper surface of the base 111 , and The second installation cylinder 113 is longitudinally disposed on the bottom surface of the base 111 , and a longitudinal through hole 1110 is formed in the middle of the base 111 , and the through hole 1110 connects the first installation cylinder 112 and the second installation cylinder 113 . The outer wall surface of the second installation cylinder 113 forms a screw structure 1131 for screwing the upper end of the battery device 2 , and the inner wall surface is formed with an installation ring 1132 that cooperates with the insulating sealing ring 16 .

The first pipe section 121 defines the above-mentioned atomization cavity 120 , and the above-mentioned liquid inlet holes 122 may be multiple, and are uniformly formed in the circumferential direction of the side wall of the first pipe section 121 . A stop ring 1231 extending toward the central axis may be provided on the inner wall surface of the second pipe section 123 near the first pipe section 123 to provide an axial resisting force to the first electrode claw 17 . The end surface of the blocking ring 1231 close to the first electrode claw 17 may be a plane perpendicular to the central axis of the second pipe section 123 , and the end surface away from the first electrode claw 17 may be a trumpet-shaped conical surface. The outer diameter of the third pipe section 125 is adapted to the inner diameter of the first installation barrel 112 , so that the third pipe section 125 is longitudinally embedded in the first installation barrel 112 and tightly fitted with the first installation barrel 112 . The height of the third pipe section 125 is equivalent to the height of the first installation barrel 112 . In some embodiments, in order to facilitate the embedding of the third pipe section 125 into the first installation cylinder 112, a guide portion 1251 is formed inwardly on the outer wall surface of the third pipe section 125 near the lower end, and the outer diameter of the guide portion 125 is smaller than A mounting barrel 112 .

In some embodiments, the casing 13 can be made of a transparent material, and its inner diameter is adapted to the outer diameter of the first installation cylinder 112, so that the lower end of the casing 13 can be sleeved on the first installation cylinder 112 in the axial direction, And tightly fit with the first installation barrel 112 . The upper end surface of the housing 13 may be slightly lower than the upper end surface of the second pipe section 123 so as to be better matched with the suction nozzle assembly 20 . The above-mentioned liquid storage cavity 130 is defined between the inner wall surface of the casing 13 and the inner wall surfaces of the first pipe section 121 and the second pipe section 123 , and an annular liquid injection is formed between the upper end of the casing 13 and the upper end of the second pipe section 123 mouth 132.

In some embodiments, the atomizing assembly 14 may include a cylindrical atomizing core 141 arranged longitudinally, a first sealing ring 142 sleeved on the upper end of the atomizing core 141 , and a second sealing ring sleeved at the lower end of the atomizing core 141 143.

The first sealing ring 142 may have an L-shaped cross section for sealing the gap between the upper end of the atomizing core 141 and the upper end of the first pipe section 121 . In some embodiments, the first sealing ring 142 may include a cylindrical first sealing portion 1421 and an annular second sealing portion 1423 connected to the upper end edge of the first sealing portion 1421. The first sealing portion 1421 is sleeved on the On the outer wall surface of the upper end of the atomizing core 141 , the second sealing portion 1423 covers the upper end surface of the atomizing core 141 . The inner diameter of the second sealing portion 1423 is preferentially larger than the aperture of the atomizing core 141 , so that when the first electrode claw 17 cooperates with the atomizing core 141 , it will not be blocked by the second sealing portion 1423 .

The second sealing ring 143 may also have an L-shaped cross-section for sealing the gap between the lower end of the atomizing core 141 and the third pipe section 125 . In some embodiments, the second sealing ring 143 may include a cylindrical third sealing portion 1431 and an annular fourth sealing portion 1433 connected to the lower end edge of the third sealing portion 1431. The third sealing portion 1431 is sleeved on On the outer wall surface of the lower end of the atomizing core 141 , the fourth sealing portion 1433 covers the lower end surface of the atomizing core 141 . The middle part of the outer wall surface of the atomizing core 141 may face the liquid inlet hole 122 . A central through hole 1410 is formed in the middle of the atomizing core 141 in a longitudinal direction. The inner diameter of the fourth sealing portion 1433 is preferably larger than the aperture of the atomizing core 141 , so that when the second electrode claw 18 cooperates with the atomizing core 141 , it will not be blocked by the fourth sealing portion 1433 .

In some embodiments, a labyrinth-shaped first ventilation groove 1420 is formed on the inner wall surface of the first sealing ring 142 , and the first ventilation groove 1420 penetrates through the inner wall surfaces of the first sealing portion 1421 and the second sealing portion 1423 . The size of the first ventilation groove 1420 can be designed to be small enough to have capillary force in the use state, so as to adjust the air flow in the liquid storage cavity 130 and the ventilation pipe 12 when the liquid storage cavity 130 is at a relatively large negative pressure The channel is turned on to achieve gas-liquid balance and prevent dry burning. In some embodiments, the second sealing ring 143 may also be provided with a labyrinth-shaped second ventilation groove 1430 on the inner wall surface. It has the same function as the first ventilation groove 1420 . In some embodiments, the first sealing ring 142 and the second sealing ring 143 have the same structure and can be used in common use, thereby facilitating automatic installation and saving the cost of mold opening of the sealing ring.

It is understandable that the first sealing ring 142 and the second sealing ring 143 may alternatively be provided with a ventilation structure, both of which have advantages and disadvantages. When only the first sealing ring 142 has a ventilation structure, if the first ventilation groove 1420 of the first sealing ring 142 leaks liquid, part of the leaking liquid will flow down from the upper end of the atomizing core 141, and be removed by the atomizing core 141 Atomize again after absorption. When only the second sealing ring 143 has a ventilation structure, although possible liquid leakage is easy to flow into the base 11 , the air supply through the second sealing ring 143 is smoother because the air flow direction in the air passage is from bottom to top. In some embodiments, the sealing silica gel of the second sealing ring 143 at the lower end is thicker, that is, the distance from the surface of the second sealing ring 143 in contact with the atomizing core 141 to the surface in contact with the ventilation pipe 12 can be better. The lower end of the atomizing core 141 is sealed by interference fit, so as to avoid liquid leakage. When the two are compared, the comparison is made with the thickness of the corresponding part of the first sealing ring 142 .

Referring to FIG. 8 together, in some embodiments, the atomizing core 141 may include a cylindrical porous body 1411 , a heating element 1412 disposed on the inner wall of the porous body 1411 , a heating element 1412 disposed on the upper end of the inner wall of the porous body 1411 and connected to the heating element 1412 The upper end is electrically connected to the first electrode 1413 , and the second electrode 1414 is disposed at the lower end of the inner wall surface of the porous body 1411 and is electrically connected to the lower end of the heating body 1412 . The porous body 1411 may be a porous ceramic in some embodiments, and may be a small-sized porous body 1411 , which may have a length of 0.8-1.2 cm and an inner diameter of 0.18-0.22 cm in some embodiments.

The heating element 1412 can be made of nickel-chromium alloy, iron-chromium-aluminum alloy, silver-palladium alloy and other materials in some embodiments, printed and sprayed on the inner surface of the body of the porous body 1411, and then formed in the porous body 1411 by sintering. The wall surface, which may include two prolate loop-shaped heating circuits B arranged in parallel in the axial direction of the porous body 1411 and a connecting circuit C connecting the two in series, the length direction of the two heating circuits B is along the length of the porous body 1411. The inner wall surface extends in the circumferential direction so that the whole is C-shaped. The heating body 1412 may further include an upper end line D and a lower end line A connected to the upper end and the lower end, respectively, so as to be electrically connected to the first electrode 1413 and the second electrode 1414, respectively.

The first electrode 1413 and/or the second electrode 1414 can be made of materials such as silver, copper, etc., and can be formed on the inner wall surface of the cylindrical porous body 1411 by coating/printing and sintering with silver paste or copper paste, and At least part of it is connected to the heating element 1412 . The first electrode 1413 and/or the second electrode 1414 may be C-shaped in some embodiments, which is usually firstly paste-printed on the heating body 1412 onto the blank of the porous body 1411, then printing or coating the electrode paste, and then Sintered together. In some embodiments, the width of the notch of the first electrode 1413 may be smaller than the width of the conductive portion 173 so as to be in electrical contact with all the conductive portions 173 of the first electrode claws 17 ; the width of the notch of the second electrode 1414 may be smaller than the width of the conductive portion 173 . The width of the portion 183 is adjusted so as to be electrically connected with all the conductive portions 183 of the second electrode claw 18 . It can be understood that the heating body 1412 can also be made of a metal heating sheet in some embodiments, the porous body 1411 is also limited to a porous ceramic material, and other suitable porous body materials are also acceptable. It can be understood that the first electrode 1413 and/or the second electrode 1414 is not limited to the C-shaped distribution at the end of the inner wall surface of the porous body 1411 , but can also be distributed over the entire circumference of the end of the inner wall surface of the porous body 1411 , which is annular.

The above-mentioned arrangement of the first electrode 1413 and/or the second electrode 1414 eliminates the need to drill holes in the porous body 1411, and the internal structure of the porous body 1411 is more complete, controllable and reliable, so the consistency of the product is well guaranteed . In addition, the use of lead wires can be avoided, thereby reducing manufacturing difficulty and production cost. This is particularly evident for the application to the miniaturized porous body 1411 .

In some embodiments, arranging the first electrode 1413 and the second electrode 1414 at both ends of the inner wall of the small-sized porous body 1411 also has many advantages, because the inner wall area of the miniaturized porous body 1411 is very small. There are two electrodes, the area of the two electrodes is too small to establish a stable electrical connection with the electrode connector, and it is also prone to short circuit problems. By arranging the first electrode 1413 and the second electrode 1414 at both ends, the first electrode can be easily The deployment of the first electrode 1413 and the second electrode 1414 can make the area of the first electrode 1413 and the second electrode 1414 larger and facilitate the establishment of a stable electrical connection with the electrode connector.

As shown in FIGS. 6 and 7 , in some embodiments, the electrode column 15 includes a central hole 150 extending upward from the lower end surface, an air outlet hole 152 formed on the side wall of the top, and a slot 154 formed on the side wall surface. The air hole 152 communicates with the central hole 150 for air intake. The engaging groove 154 is used for engaging with the insulating sealing ring 16 . An engaging groove 160 is formed on the outer wall surface of the insulating sealing ring 16 for engaging with the mounting ring 1132 of the base 11 .

The first electrode claw 17 may be made of phosphor bronze or 316 stainless steel in some embodiments, and a gold-plated layer may be provided on the surface thereof. The first electrode claw 17 is preferably made of phosphor bronze material, which has relatively low impedance. The first electrode claw 17 may include a mounting portion 171 embedded in the inner wall surface of the second pipe section 123 , three extending portions 172 connected with the mounting portion 171 , and three conductive portions 173 respectively connected with the three extending portions 172 . . Each extension portion 172 and the corresponding conductive portion 173 form an elastic conductive arm of the first electrode claw 17 . It can be understood that the number of the elastic conductive arms of the first electrode claw 17 is not limited to three, one or more can be used, and having multiple elastic conductive arms can make electrical connection more reliable and assembly more convenient.

The mounting portion 171 can be cylindrical in some embodiments, and has a longitudinal fracture 1710 penetrating through the edges of both sides. The presence of the fracture 1710 can cause deformation during installation, so as to ensure that the mounting portion 171 can better connect with the second pipe section 123 The inner wall is fixed. Specifically, a trumpet-shaped guide surface 1210 is provided at the intersection of the second pipe section 123 and the first pipe section 121 , and the guide surface 1210 is used to guide the first electrode claw 17 into the second pipe section 123 in the axial direction. The mounting portion 171 of an electrode claw 17 exerts a radially inward component force, so that the fracture 1710 of the mounting portion 171 is closed, the outer diameter is reduced, and it can be inserted into the second pipe section 123; after being installed in place, the mounting portion 171 provides A reaction force is applied to the inner wall surface of the second pipe section 123 , so that the second pipe section 123 can be firmly fixed. It can be understood that the mounting portion 171 can also be integrated with the second pipe section 123 in some embodiments. In some embodiments, the mounting portion 171 can also be inserted into the upper end of the central through hole 1410 of the atomizing core 141 in the axial direction, and elastically abutted and fixed with the first electrode 1413 , and the elastic conductive arm can be extended to the ventilation pipe 12 .
