Referring to fig. 1 to 3, an atomizer 10 according to an embodiment of the present utility model includes a mounting sleeve 100, a liquid guiding member 200 and a heat generating member 300. The liquid guide 200 is provided to the mounting sleeve 100 for conducting the nebulizable medium. The heating element 300 is used for heating an nebulizable medium, the heating element 300 comprises a heating element 310 and a heat conducting substrate 320, and the heating element 300 is formed on the heat conducting substrate 320 and is integrally arranged with the heat conducting substrate 320. The heat generating member 300 is provided to the mounting sleeve 100 to keep the liquid guiding member 200 and the heat conducting substrate 320 in contact with each other.

In the above-described atomizer 10, since the heat generating body 310 is formed on the heat conducting substrate 320, the heat generating body 310 can transfer heat to the heat conducting substrate 320. Since the thermally conductive substrate 320 itself is not a direct heating element, it may be shaped to more facilitate attachment to the liquid guide 200. Meanwhile, the heating element 300 and the liquid guide 200 are both arranged on the mounting sleeve 100, so that the heating element 300 and the liquid guide 200 can have stable relative positions through the mounting sleeve 100, and even if the heating element and the liquid guide 200 can keep fit. So set up, can guarantee the effect that generates heat the atomizing of piece 300 heating, make atomizer 10 whole atomization effect better.

In addition, compared with the mode of manually pressing the heating sheet to fix the heating sheet and the liquid guiding cotton in the related art, in the embodiment, the heating piece 300 and the liquid guiding piece 200 are both arranged on the mounting sleeve 100 without manual participation, so that the automation degree is higher, and the automation degree in the production process is convenient to improve.

Further, since the heat conducting substrate 320 is not used as a direct heating element, the heat conducting substrate 320 is more free to design, and can be designed to have a larger contact area with the nebulizable medium, so as to facilitate heating and nebulizing the nebulizable medium. In addition, when the heat generating body 310 in the embodiments heats the nebulizable medium through the heat conducting substrate 320, the temperature of each area on the heat conducting substrate 320 is uniform or can be uniform, so that the heating is more uniform, compared with the wire-shaped and net-shaped heat generating structure.

Further, since the heating body 310 is directly formed on the heat conducting substrate 320 in each embodiment, there is no gap between the two, and the heat conducting performance is good. Compared with the mesh-shaped or wire-shaped heating structure in the conventional technology, the shape of the heating element 310 formed on the heat conducting substrate 320 in each embodiment is more consistent, i.e. is less prone to deformation, so that the heating effect is better.

Taking the heat generating body 310 as an example, the heat generating body 310 may be formed on the heat conducting substrate 320 by chemical deposition, magnetron sputtering, spraying, printing, evaporation, or the like. And, the heating body 310 may be provided with a preset shape by means of etching. Thus, the shape of the heating element 310 can be more uniform and regular, and the occurrence probability of the situation that the local temperature difference is large due to the uneven and irregular specific structure distribution of the heating element 310 is reduced.

In one embodiment, the heating element 310 may include molybdenum (Mo), which has a higher melting point than other materials used as the heating element 310, and is not easy to generate substances harmful to human body when heating. In addition, the temperature detection is easy to realize because of the high resistance temperature coefficient of molybdenum metal. It is understood that feedback adjustment of the atomization effect of the atomizer 10 can be facilitated by detecting the temperature of the heat generating body 310.

Of course, in some embodiments, other heat generating materials may be used for the heat generating body 310, which will not be described herein.

In one embodiment, thermally conductive substrate 320 comprises single crystal silicon, which is convenient to mold and more convenient to manufacture. Meanwhile, the monocrystalline silicon has higher heat conductivity coefficient, and can well conduct heat generated by the heating element 310, so that the probability of the situation that the local temperature difference of the heating element 300 is large is reduced, and the nebulizable medium is heated more uniformly. In addition, compared with ceramic materials, the monocrystalline silicon is not manufactured through a powder sintering process, so that dust does not fall off in the use process, and the aerosol obtained through atomization has better taste.

Referring to fig. 3, in one embodiment, the thermally conductive substrate 320 is a porous member for conducting an nebulizable medium. In this manner, the thermally conductive substrate 320 is also capable of conducting the nebulizable medium, while more fully heating and conducting the nebulizable medium. It is understood that the porous member may comprise a capillary material having a fibrous or porous structure. The capillary material forms a plurality of small pores or channels through which the nebulizable medium can be transported or conveyed by capillary action.

In this embodiment, the atomized micropores 322 may be formed in the single crystal silicon by etching. Compared with ceramic materials, the monocrystalline silicon has better porosity, can reduce the occurrence probability of carbon deposition caused by hole blockage in the conductive nebulizable medium, and improves the atomization effect.

With continued reference to FIG. 3, in one embodiment, a side of the thermally conductive substrate 320 facing away from the heat generating body 310 is configured to contact the liquid guide 200 to deliver an nebulizable medium. And, the side of the heat conductive substrate 320 facing away from the heating body 310 is recessed to form a liquid storage cavity 321. The liquid storage cavity 321 can contain the nebulizable medium, so the content of the nebulizable medium at the heating element 300 can be improved through the liquid storage cavity 321, and the problem of insufficient oil supply is avoided.

With continued reference to fig. 3, in one embodiment, the heat generating body 310 includes a heat generating portion 311 and an electrode portion 312, both formed on a heat conducting substrate 320, the electrode portion 312 being capable of being connected to a conductive pin 800, which will be described below. The conductive thimble 800 can provide power to the electrode portion 312, and the heating portion 311 can generate heat under the power to atomize the nebulizable medium to form aerosol. The two electrode portions 312 are respectively connected to both ends of the heat generating portion 311 to form a conductive loop.

With continued reference to fig. 3, in one embodiment, the heat generating portion 311 may be formed on the heat conductive substrate 320 in a reciprocally curved shape. Of course, the heat generating portion 311 may be formed on the heat conducting substrate 320 in other shapes such as a net shape, a comb shape, and a saw tooth shape.

Referring to fig. 4, in one embodiment, the liquid guiding member 200 and the heat generating member 300 are disposed in the mounting sleeve 100. The mounting sleeve 100 comprises a first limiting part 110 and a second limiting part 120, wherein the first limiting part 110 is abutted against one side of the liquid guide piece 200, which is away from the heating piece 300, and the second limiting part 120 is abutted against one side of the heating piece 300, which is away from the liquid guide piece 200. That is, the first limiting portion 110 and the second limiting portion 120 are respectively abutted against the sides of the liquid guiding member 200 and the heat generating member 300 facing away from each other. In this way, by the first stopper 110 and the second stopper 120 being engaged with each other, the liquid guide 200 and the heat generating element 300 can be held and fixed in the mounting sleeve 100, and the heat conductive substrate 320 can be stably bonded to the liquid guide 200.

Referring to fig. 5, in one embodiment, the inner wall of the mounting sleeve 100 is recessed to form a receiving groove 130, and the groove wall of the receiving groove 130 abuts against two opposite sides of the heat generating component 300 with the second limiting portion 120. Thus, the heat generating element 300 can have a stable position in the mounting sleeve 100 through the groove wall of the accommodating groove 130 and the second limiting portion 120.

Specifically, the second limiting portion 120 may be located on a groove wall of the accommodating groove 130 and protruding into the mounting sleeve 100. The groove wall of the accommodating groove 130 and the second limiting portion 120 are respectively abutted against two opposite sides of the heating element 300, so that the heating element 300 has a stable position in the mounting sleeve 100.

Alternatively, the second limiting portion 120 may be located at the bottom of the mounting sleeve 100, and the second limiting portion 120 extends toward the inside of the mounting sleeve 100. The second limiting portion 120 is also convenient to cooperate with the groove wall of the accommodating groove 130 to jointly abut against the heating element 300.

Referring to fig. 2 and 4 again, the atomizer 10 further includes a conductive thimble 800, one end of the conductive thimble 800 abuts against the heating element 300, and the other end of the conductive thimble 800 is used for being connected with a power source to transmit the power of an external power source to the heating element 300, so that the heating element 300 heats. In this embodiment, the accommodating groove 130 is matched with the second limiting portion 120, so that the heating element 300 has a stable relative position, so as to be in abutting fit with the conductive thimble 800.

In one embodiment, the liquid guide 200 is also a porous member. Similar to the thermally conductive substrate 320, the liquid guide 200 may also include a capillary material having a fibrous or porous structure. The capillary material forms a plurality of small pores or channels through which the nebulizable matrix can be transported or conveyed by capillary action.

Since the liquid guide 200 may not serve as a substrate of the heat generating body 310, the liquid guide 200 may have a sponge-like or foam-like structure. Examples of suitable materials include sponge or foam materials, ceramic or graphite-based materials in the form of fibres or sintered powders, foamed metal or plastics materials, for example fibrous materials made from spun or extruded fibres, such as cellulose acetate, polyester or bonded polyolefin, polyethylene, polyester or polypropylene fibres, nylon fibres or ceramics.

Of course, the porous member may comprise any other suitable material or combination of materials.

It can be understood that, since the heater 310 can have a stable relative position in the mounting sleeve 100 by the cooperation of the groove wall of the accommodating groove 130 and the second limiting portion 120, the position between the heater 300 and the liquid guiding member 200 is not unstable even if the liquid guiding member 200 is made of some flexible material.

Referring to fig. 4, in one embodiment, a side of the liquid guiding member 200 facing away from the heat generating member 300 is concavely provided with a liquid collecting hole 210. The liquid collecting holes 210 can intensively contain the nebulizable medium to increase the content of the nebulizable medium at the liquid guiding member 200.

In one embodiment, the mounting sleeve 100 is a soft elastic member. In this way, the heat generating member 300 can be more conveniently locked into the accommodating groove 130. Meanwhile, the soft elastic piece has a movement trend of returning to the original state after deformation, so that the positions of the heating piece 300 and the liquid guide piece 200 can be supported more tightly, and the positions of the heating piece and the liquid guide piece are more stable. The mounting sleeve 100 may be a soft elastic member such as silicone rubber.

Of course, in some embodiments, the mounting sleeve 100 may also be a non-soft elastic member. In this embodiment, the mounting sleeve 100 may include a first mounting portion (not shown) and a second mounting portion (not shown) that are detachably connected, and the heat generating component 300 may be conveniently mounted in the mounting sleeve 100 by separating the first mounting portion from the second mounting portion.

In this manner, the nebulizable medium in the reservoir 410 can be conducted to the liquid guide 200 in the mounting sleeve 100 and conducted to the heat generating element 300 via the liquid guide 200, and the heat generating element 300 can nebulize the nebulizable medium into aerosol for inhalation by the user.

With continued reference to fig. 6 and 7, in one embodiment, the connection seat 500 is provided with a liquid inlet channel 510 that communicates with the mounting sleeve 100, and the liquid inlet channel 510 is further communicated with the oil storage cavity 410. The nebulizable medium in the reservoir 410 can be conducted through the feed channel 510 to the mounting sleeve 100. The number of the liquid inlet channels 510 may be plural so that there is sufficient nebulizable medium at the heat generating element 300. The number of the liquid inlet channels 510 may be two.

The outer circumference of the mounting sleeve 100 is provided with an annular protrusion 140, and the annular protrusion 140 abuts against the cavity wall of the mounting cavity 520. Thus, leakage of nebulizable medium from between the mounting chamber 520 and the outer wall of the mounting sleeve 100 can be avoided by the annular projection 140. It can be understood that the mounting sleeve 100 is a soft elastic member, so that the annular protrusion 140 abuts against the wall of the mounting cavity 520, so that the sealing property between the mounting cavity 520 and the mounting sleeve 100 can be improved, and the nebulizable medium is introduced into the mounting sleeve 100 and is nebulized into aerosol for the user by the heating element 310.

Referring to fig. 2 and 6, in one embodiment, the atomizer 10 further includes a base 600 connected to the connection base 500.

Accordingly, the inside of the oil storage chamber 410 can be sealed relatively by the sealing action of the sealing sleeve 700, and leakage of the nebulizable medium from the gap between the connection seat 500 and the housing 400 can be avoided.

With continued reference to fig. 9, the sealing sleeve 700 may be provided with a first fitting 710 and a second fitting 720.
