Referring to fig. 1-2, an embodiment of the present utility model provides an atomizer 100, which includes an oil cup 10 and an atomization assembly 20, wherein the lower end of the oil cup 10 is opened, an air suction hole 11 is formed at the upper end for a user to suck and use, an air duct 12 is formed at the upper end of the oil cup 10 along the edge of the air suction hole 11, and a liquid storage cavity 13 for storing atomized liquid is formed between the air duct 12 and the inner wall of the oil cup 10.

The atomizing subassembly 20 is installed to the lower extreme opening of oil cup 10, including heating support 22, heating subassembly and oil cup support 21, the top of heating support 22 is equipped with location boss 224, heating subassembly includes liquid guide 24 and heat-generating body 23, liquid guide 24 includes connecting portion 243 and first liquid guide portion 241, connecting portion 243 is equipped with the locating hole 244 with location boss 224 adaptation, connecting portion 243 installs in the top of heating support 22 through the cooperation of locating hole 244 and location boss 224, one side of heating support 22 is located in the subsides of first liquid guide portion 241, heat-generating body 23 is held and is positioned between heating support 22 and first liquid guide portion 241.

The oil cup support 21 is provided with a mounting cavity 2101 with an opening at the bottom and used for mounting the heating support 22 and the heating component, the oil cup support 21 is sleeved on the heating support 22 from top to bottom, so that the heating support 22 and the heating component are mounted in the mounting cavity 2101 of the oil cup support 21, and a positioning boss 224 of the heating support 22 and a connecting part 243 of the liquid guide 24 are tightly attached to the top wall of the mounting cavity 2101, so that the connecting part 243 is fixedly clamped between the top of the heating support 22 and the top wall of the mounting cavity 2101, and meanwhile, the first liquid guide part 241 is additionally clamped between the outer side wall of the heating support 22 and the inner side wall of the mounting cavity 2101. The oil cup support 21 is provided with a liquid inlet channel contacted with a liquid guide 24, and the liquid guide 24 is used for guiding atomized liquid in the liquid storage cavity 13 to the heating body 23 so as to heat and atomize the atomized liquid through the heating body 23.

In this embodiment, the connection portion 243 and the first liquid guiding portion 241 in the liquid guiding portion 24 are generally in an inverted L-shaped structure, so that the liquid guiding portion 24 is suspended by the connection portion 243 and mounted on the heat generating support 22, when the heat generating support 22 is assembled into the oil cup support 21, the first liquid guiding portion 241 of the liquid guiding portion 24 is prevented from being separated and deformed due to extrusion of the oil cup support 21 along the assembling direction.

Specifically, an atomization cavity 221 is formed on one side of the heating support 22 corresponding to the first liquid guiding portion 241, and an air outlet 225 communicated with the atomization cavity 221 is formed on the positioning boss 224; in this embodiment, the top end of the oil cup holder 21 is formed with a first mounting portion 215, a mounting channel 216 corresponding to the air outlet 225 is formed in the first mounting portion 215, and one end of the air duct 12, which is far away from the air suction hole 11, is inserted into and connected to the mounting channel 216, and is hermetically connected to the inner wall of the mounting channel 216 through a first sealing member 25, so that the inside of the air duct 12 is communicated with the atomizing chamber 221. When the user sucks, the aerosol generated in the atomizing chamber 221 after the heating body 23 is heated may be introduced into the suction hole 11 through the air outlet 225 and the air guide pipe 12 and sucked by the user.

Of course, the air outlet 225 of the atomizing chamber 221 is disposed on the positioning boss 224 in this embodiment only to make the structure of the atomizing assembly 20 more reasonable and compact; in other embodiments, the location of the air outlet 225 on the heat generating bracket 22 may also be set according to the position of the air duct 12 of the oil cup 10.

In a preferred embodiment, as shown in fig. 3, the liquid guiding body 24 further includes a second liquid guiding portion 242, and the connecting portion 243 is connected between the first liquid guiding portion 241 and the second liquid guiding portion 242, that is, the liquid guiding body 24 has a substantially inverted U-shaped structure and is inverted on the heat generating bracket 22, so that the first liquid guiding portion 241 and the second liquid guiding portion 242 are respectively attached to two sides of the heat generating bracket 22, and the attaching effect between the liquid guiding body 24 and the heat generating bracket 22 is further improved.

The liquid inlet channel includes a first liquid inlet slot 211 and a second liquid inlet slot 213 respectively opened on two opposite outer sidewalls of the oil cup support 21, a first liquid inlet 212 connected with a first liquid guiding portion 241 is opened in the first liquid inlet slot 211, and a second liquid inlet 214 connected with a second liquid guiding portion 242 is opened in the second liquid inlet slot 213, as shown in fig. 4. The upper ends of the first liquid inlet tank 211 and the second liquid inlet tank 213 are both communicated with the liquid storage cavity 13, so that the liquid guide 24 is contacted with the atomized liquid in the two liquid inlet ports, and thus, by arranging the two liquid guide parts of the liquid guide 24 at different sides of the heating support 22, when only the second liquid guide part 242 contacts the atomized liquid, the atomized liquid absorbed by the second liquid guide part 242 can be conducted into the first liquid guide part 241 through the connecting part 243, and when the connecting part 243, one of the first liquid guide part 241 and the second liquid guide part 242 contacts the atomized liquid, the other two parts can absorb and store the atomized liquid, compared with the structure that only one side liquid guide part is used for guiding liquid in the prior art, so that the situation that the heating body 23 is dry-burned due to the fact that the atomized liquid is not absorbed by the liquid guide part when the atomizer 100 is not used at a different angle is avoided.

Preferably, as shown in connection with FIG. 5, the inner side wall of the mounting cavity 2101 is provided with a draft inclined surface 2102 at one end close to the opening; in this way, when the liquid guide 24 and the heat generating bracket 22 are assembled in the liquid guide mounting chamber 2101, the pressing action of the inner side wall of the mounting chamber 2101 on the liquid guide 24 is reduced.

The outer wall of the oil cup support 21 is provided with an annular groove 218 below the first liquid inlet groove 211 and the second liquid inlet groove 213, an annular second sealing piece 26 is arranged in the annular groove 218, and when the oil cup support 21 is installed in the oil cup 10, sealing connection with the inner wall of the oil cup 10 is realized through the second sealing piece 26.

Further, the liquid passing area of the first liquid inlet 212 is larger than that of the second liquid inlet 214, so that the liquid feeding rate of the first liquid guiding portion 241 for the heating body 23 is ensured, meanwhile, different liquid feeding rates are realized due to different liquid passing areas, and meanwhile, the external atmosphere can return air to the liquid storage cavity 13 through the second liquid inlet 214 due to the differential speed of the fluid between the first liquid inlet 212 and the second liquid inlet 214.

It will be appreciated that, since only the first liquid guiding portion 241 is in direct contact with the heating element 23 in the first liquid guiding portion 241 and the second liquid guiding portion 242, when the heating element heats and atomizes the atomized liquid on the first liquid guiding portion 241, the consumption of the atomized liquid on the first liquid guiding portion 241 and the consumption of the atomized liquid on the second liquid guiding portion 242 are inconsistent, so that the first liquid inlet 212 and the second liquid inlet 214 have different liquid discharging rates, that is, the first liquid inlet 212 is faster, and the second liquid inlet 214 is slower, so that the external atmosphere can conveniently return air from the second liquid inlet 214 to the liquid storage cavity 13 by virtue of the flow rate difference. In one embodiment, the opposite sides of the heating support 22 are respectively formed with accommodating grooves 222 adapted to the first liquid guiding part 241 and the second liquid guiding part 242; during assembly, the connecting portion 243 is firstly mounted on the top of the heating bracket 22 through the cooperation of the positioning hole 244 and the positioning boss 224, and then the first liquid guiding portion 241 and the second liquid guiding portion 242 at the two ends are respectively bent downwards and then mounted in the accommodating grooves 222 at the two sides of the heating bracket 22, so that the assembly is convenient and quick.

Further, the positioning boss 224 is formed with an upper limit portion 226 protruding toward the two receiving grooves 222, and a lower limit portion 227 protruding toward the bottom of each receiving groove 222. With such a structure, after the liquid guide 24 is assembled to the heat generating bracket 22, the first liquid guide portion 241 and the second liquid guide portion 242 can be respectively stopped and positioned by the upper limit portion 226 and the lower limit portion 227 when being accommodated and mounted in the accommodating groove 222, and the first liquid guide portion 241 and the second liquid guide portion 242 of the liquid guide 24 can be further prevented from being deformed by being extruded along the vertical direction when the heat generating bracket 22 is assembled into the inside of the oil cup bracket 21. It should be noted that, the two side ends of the heating support 22 may also be respectively formed with side limiting portions, and each accommodating groove 222 is formed by jointly enclosing an upper limiting portion 226, a lower limiting portion 227 and the side limiting portions.

It should be understood that the liquid guiding body 24 in this embodiment has a single-layer structure, and may be made of a flexible porous material such as a non-woven fabric, a polymer cotton or a foamed oil absorbent cotton. In other embodiments, the liquid guiding body 24 may also have a multi-layer structure, for example, the inner layer contacting the heating body 23 may be made of a porous ceramic material, and the outer layer is made of a flexible porous material such as non-woven fabric, high molecular cotton or foaming oil absorbing cotton; for another example, the liquid guiding body 24 is formed by overlapping a plurality of layers of non-woven fabrics, the liquid guiding speed of the non-woven fabric layer close to the heating body 23 is sequentially higher than that of the non-woven fabric layer far away from the heating body 23, and the non-woven fabric layer positioned in the middle layer has a saturated liquid absorbing capacity (namely, strong liquid storage capacity) which is higher than that of the non-woven fabric layers at the inner side and the outer side.

In an alternative embodiment, as shown in fig. 6, the top of the oil cup support 21 may be provided with a third liquid inlet 219 contacting with the connection portion 243, so as to improve the liquid feeding efficiency of the liquid guiding body 24 for the heating body 23, and reduce the possibility of dry burning of the heating body 23. In the practical application process, the second liquid inlet 214 and the third liquid inlet 219 can be selectively arranged according to the practical situation, for example, under the condition that the structures of the first liquid inlet 211 and the first liquid inlet 212 are unchanged, the oil cup support 21 can be simultaneously provided with the second liquid inlet 214 and the third liquid inlet 219, and only the third liquid inlet 219 can be arranged without canceling the arrangement of the second liquid inlet 214.

In the present embodiment, at least one of the oil cup holder 21 and the heat generating holder 22 defines at least one air return passage, one end of which communicates directly or indirectly with the first liquid inlet tank 211 and/or the second liquid inlet tank 213, and the other end communicates directly or indirectly with the outside of the atomizer 100. When a user sucks, the atomized liquid in the liquid storage cavity 13 is absorbed by the liquid guide 24 and heated for atomization, so that negative pressure is formed in the liquid storage cavity 13, and when external air is mixed with aerosol, a part of gas enters the liquid storage cavity 13 from the air return channel through the corresponding liquid inlet groove, so that the air pressure in the liquid storage cavity 13 is balanced, and the situation of unsmooth liquid guide is avoided.

Specifically, the air return channel includes an air return channel disposed on the heating support 22 and communicated with the atomizing cavity 221, one end of the air return channel is communicated with the second liquid inlet 214 through the second liquid guiding portion 242, and the other end is communicated with the atomizing cavity 221 or the air inlet of the atomizer 100, so that the first liquid inlet channel 211 is utilized as a main liquid inlet path, the second liquid inlet channel 213 is utilized as an air return path, that is, the air return channel and the liquid outlet channel are separately and independently disposed, and gas-liquid separation is realized. Of course, in other embodiments, the air return tank may also be connected to the first liquid inlet 212 through the first liquid guiding portion 241, and may be specifically set according to actual needs.

Further, a micro groove 217 is arranged on the groove wall of the first liquid inlet groove 211 and/or the second liquid inlet groove 213, and the first liquid inlet 212 and the second liquid inlet 214 are correspondingly positioned at the bottom of the micro groove 217; the micro-groove 217 extends upwards to the upper part of the first liquid inlet groove 211/the second liquid inlet groove 213 or is directly communicated with the liquid storage cavity 13, so that after air in the air return groove flows back into the liquid inlet groove through the liquid inlet opening, the air can enter the liquid storage cavity 13 along the micro-groove 217, the size of bubbles formed by the air return is reduced, and the situation that the liquid inlet groove is blocked by the bubbles to cause dry burning is prevented.

Further, the second liquid inlet 214 has a level greater than that of the first liquid inlet 212, so that the pressure of the atomized liquid at the second liquid inlet 214 is smaller than that of the atomized liquid at the first liquid inlet 212, and air enters from the second liquid inlet 214 and is limited by the micro-groove 217 to form small bubbles into the liquid storage cavity 13 during air return.

In one embodiment, as shown in fig. 1 and 2, the atomizing assembly 20 further includes a base assembly including a base 28 and an elastic pad 27 stacked on the base 28, the heat generating bracket 22 is mounted to the top end of the elastic pad 27 and protrudes downward to form a second mounting portion 228 passing through the elastic pad 27 and the base 28, and an air inlet hole 229 communicating with the atomizing chamber 221 is formed in the second mounting portion 228; the heating element 23 includes two sheet-shaped electrode portions 231 and a heating portion 232 connected in series between the two fixing portions, wherein the lower ends of the two electrode portions 231 are bent through the portion of the elastic pad 27 to form a conductive portion 233, the conductive portion 233 is clamped and fixed between the elastic pad 27 and the base 28, and an electrode hole 281 for the electrode column to penetrate is formed in the base 28 at a position corresponding to the conductive portion 233. When the atomizer 100 of the present embodiment is assembled to the atomizing device 200, the electrode column in the atomizing device 200 passes through the electrode hole 281 to be abutted to the conductive portion 233, and the elastic pad 27 is utilized to form elastic contact between the electrode column and the conductive portion 233, so that stable electrical connection is ensured, and meanwhile, the welding process is reduced.

As shown in fig. 7, the present utility model also discloses an atomizing apparatus 200, the atomizing apparatus 200 includes a main body and an atomizer 100, and the specific structure of the atomizer 100 refers to the above-described embodiment.

The main body includes a housing 201, a power supply 203, a mounting bracket 202, a controller (not shown) and a microphone switch (not shown) disposed in the housing 201, wherein the power supply 203, the controller and the microphone switch are all fixedly connected with the mounting bracket 202, and the atomizer 100 is mounted on the mounting bracket 202, and can be detachably connected in a plugging or magnetic attraction manner or fixedly connected in a fastening manner, so that the heating element 23 is electrically connected with the power supply 203; the controller is electrically connected with the power supply 203 and the microphone switch respectively, and when a user sucks, the microphone switch is triggered to generate a signal, so that the controller controls the power supply 203 to supply power to the heating body 23 of the atomizer 100 according to the signal, and then the aerosol is generated by heating.

In the foregoing embodiments, the descriptions of the embodiments are emphasized, and for parts of one embodiment that are not described in detail, reference may be made to the related descriptions of other embodiments.

The foregoing is a description of the embodiments of the present utility model, and is not to be construed as limiting the utility model, since modifications in the detailed description and the application scope will become apparent to those skilled in the art upon consideration of the teaching of the embodiments of the present utility model.
