Detailed Description

In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the invention, whereby the invention is not limited to the specific embodiments disclosed below.

Referring to fig. 1, 2, 3, 4, 5 and 6, the present application provides an atomizing assembly 11, which includes an atomizing portion 200 and a supporting portion 100. Specifically, the support portion 100 has a substantially hollow tubular shape, and may have a shape of a cylindrical tube, an elliptical tube, a square tube, or the like, and the shape of the base body is described herein for clarity of illustration, and is not limited to the shape of the support portion 100. The support portion 100 is provided with a hollow pipe 110 penetrating in the axial direction. The side peripheral wall of the hollow pipe 110 is provided with a feed hole 120 for conveying the atomizing medium, which can be considered as a wall of the hollow tubular support 100 through which the feed hole 120 is provided. The atomizing medium may be a material capable of transmitting and supplying volatile components, such as smoke oil, etc., through the atomizing area 200.

The atomizing unit 200 is disposed in the hollow pipe 110 of the support unit 100 and covers the feed hole 120, which may be considered that the support unit 100 is sleeved on the outer circumferential surface 201 of the atomizing unit 200 through the hollow pipe 110, that is, the atomizing unit 200 is disposed on the inner wall surface of the side circumferential wall of the hollow pipe 110, and the outer circumferential surface of the atomizing unit 200 seals the feed hole 120. As shown in fig. 3 and 7, the atomizing unit 200 and the inner peripheral surface 111 of the hollow tube 110 of the support unit 100 form a gas passage 130, that is, at least a part of the outer peripheral surface 201 of the atomizing unit 200 and the inner wall surface of the side peripheral wall of the hollow tube 110 form a gas passage 130, and the gas passage 130 extends in the axial direction of the support unit 100. The atomizing part 200 is in contact with the atomizing medium through the feed hole 120 to transfer the atomizing medium to the outer peripheral surface 201 of the atomizing part 200, i.e., from the outer peripheral surface 201 of the atomizing part 200 into the gas passing passage 130.

As shown in fig. 1 to 7, the support portion 100 is provided so as to be able to suppress transmission of the atomized medium from the outer wall surface 101 of the support portion 100 or the inside of the support portion 100 to the inner peripheral surface 111 of the hollow pipe 110. For example, in some embodiments, the support 100 is made of a non-porous material and the atomizing portion 200 is made of a porous material having a certain porosity. As another example, in other embodiments, both the support portion 100 and the atomizing portion 200 are made of a porous material having a certain porosity, and the porosity of the support portion 100 is lower than that of the atomizing portion 200. It will be appreciated that the atomizing area 200 is made of a porous material into which an atomizing medium such as tobacco tar can penetrate for delivery. If the support 100 is made of a non-porous material or a porous material having a low porosity, it is difficult for an atomized medium such as tobacco tar to penetrate into the support 100 and be transferred inside. In addition, the advantages of such an arrangement include that the support portion 100 has a lower porosity and a higher compressive strength, which can significantly enhance the overall structural strength of the atomizing assembly 11, and facilitate assembly of the product.

The porous material may be ceramic, glass, or the like, and more specifically, zirconia, silica, alumina, or the like may be preferable. The porous material from which the atomizing part 200 is made may have a porosity ranging from 20% to 80%, and preferably, the porous material from which the atomizing part 200 is made may have a porosity ranging from 40% to 80%. The porosity of the porous material of the atomizing part 200 can be adjusted according to the composition of the smoke liquid, for example, when the viscosity of the atomizing medium such as the smoke oil is large, the porous material with high porosity can be selected to be used for the atomizing part 200 so as to ensure the liquid guiding effect. The porosity of the support portion 100 is preferably 20% or less, and in principle, the lower the porosity of the support portion 100 is, the better.

The atomizing core of traditional electron cigarette can form a plurality of liquid drops in the atomizing core along with the influence of time and gravity at actual course of working, and the liquid drop can constantly collect and not drip under the effect of surface tension, and then the condition that the atomizing core probably takes place to block up, and the miaow head inside the electron cigarette can not detect the air current and change when then the user pumps to lead to the unable work of atomizing core.

Compared to the conventional electronic cigarette, the atomization assembly 11 of the present application at least has the following advantages:

first, the atomized medium may contact the atomizing part 200 through the feed hole 120, and the atomizing part 200 may transfer the atomized medium therein, and a part of the atomized medium may be transferred into the gas passing channel 130 and atomized in the gas passing channel 130 to form aerosol for suction. It should be emphasized that, as shown in fig. 1, 2 and 3, the air passage 130 is formed by enclosing the atomizing unit 200 with the inner peripheral surface 111 of the hollow pipe 110 of the support unit 100, that is, a part of the air passage 130 is the atomizing unit 200, and the other part is the support unit 100, so that only part of the outer peripheral surface of the atomizing unit 200 will transmit the atomized medium into the air passage 130, while the support unit 100 can inhibit the transmission of the atomized medium from the outer wall surface of the support unit 100 or the inside of the support unit 100 to the inner peripheral surface of the hollow pipe 110, in particular, inhibit the transmission of the atomized medium to the inner peripheral surface of the support unit 100 of the hollow pipe, so that the air passage 130 is prevented from being blocked due to too high an amount of the atomized medium to be introduced into the air passage 130 per unit time, and at the same time, the possibility that the liquid film is formed by the aggregation of the inner peripheral droplets of the pipe of the air passage 130 due to the surface tension, thereby blocking the air passage 130 is reduced, and the conduction of the air passage 130 is ensured. In this way, when the user sucks, the relevant equipment can always detect the change of the air flow through the air passage 130, and when the change of the air flow is detected, the atomization assembly 11 can normally start to work;

Secondly, compare in addition add parts such as sensing pipeline that are used for detecting the air current and change, the scheme of this application can be regarded as to the transformation of atomizing core structure, avoids the gas passage 130 to be stopped up through the quantity of the atomizing medium that the control got into in the gas passage 130, and technology and structure are simpler on the one hand, can reduce manufacturing cost and manufacturing degree of difficulty, and on the other hand has practiced thrift the inner space of product, is favorable to realizing simplifying, the miniaturization of product, more is favored by the user.

In some of these embodiments, the atomizing portion 200 and the support portion 100 may be integrally sintered. The atomization part 200 and the supporting part 100 are directly sintered into a whole, so that the structure is more reliable, the assembly efficiency is effectively improved, and the automatic production is convenient. Sintering may be to bond green solid particles of porous materials such as ceramics with each other at high temperature, grow grains, gradually decrease voids (pores) and grain boundaries, shrink the total volume by mass transfer, increase the density, and finally become a compact polycrystalline sintered body having a certain microstructure. It should be noted that, the non-porous material and the porous material may be connected by sintering, and this process does not generate harmful substances, so that the safety of the atomizing core may be ensured.

Referring to fig. 3, 4 and 6, in some embodiments, the atomizing part 200 is provided with an atomizing chamber 210 penetrating therethrough, the atomizing chamber 210 is juxtaposed with the gas passing channel 130, and the gas passing channel 130 and the atomizing chamber 210 are both disposed along the axial direction of the supporting part 100. The atomizing portion 200 separates the atomizing chamber 210 from the gas passage 130, which may be regarded as the atomizing chamber 210 being not in communication with the gas passage 130 in the radial direction. The beneficial effects of this setting include at least:

firstly, the atomizing part 200 can guide the atomized medium part transferred in the atomizing cavity 210 into the atomizing cavity 210, and when the atomizing cavity 210 and the gas passing channel 130 are in a conducting state, aerosol can be generated by the atomizing cavity and the gas passing channel, so that the concentration of the aerosol and the suction taste of a user are ensured;

secondly, compared to the gas passing channel 130, the atomizing chamber 210 is substantially formed by the independent enclosing of the atomizing part 200, so that the atomizing medium in the atomizing chamber 210 may be supplied more and more rapidly by the atomizing part 200; in extreme cases, even if the atomizing cavity 210 is blocked due to too much atomizing medium in the atomizing cavity 210, the air passage 130 can be kept in a conducting state, the air passage 130 can always detect the change of air flow when the user sucks, the atomizing assembly 11 can start to work when the change of air flow is detected, and meanwhile, the atomizing cavity 210 is promoted to be blocked and accumulated with atomizing medium for atomizing, so that the atomizing cavity 210 is conducted again;

Third, when the atomizing chamber 210 is blocked by the atomizing medium, the atomizing assembly 11 just starts to work when the user just starts to suck, the atomizing chamber 210 may be in a non-conducting state, and the atomizing chamber 210 may not generate aerosol at the first time; however, the unblocked gas passage 130 has a certain amount of atomized medium therein, and can be atomized to form a certain amount of aerosol in the first time to immediately supply the suction of the user, so as to ensure better user experience.

It should be noted that, when the above embodiment refers to the air passage 130 and the atomizing chamber 210, the number of the air passage 130 and the atomizing chamber 210 is not specifically limited, and it is understood that at least one air passage 130 and at least one atomizing chamber 210 may be provided.

Specifically, in the embodiment shown in fig. 3 and 4, the atomizing chamber 210 is provided one, the air passing passages 130 are provided two at opposite sides of the atomizing chamber 210, respectively, and each air passing passage 130 is radially separated from the atomizing chamber 210 by a side peripheral wall of the atomizing part 200.

In other embodiments, only one gas passing channel 130 may be provided, and a plurality of atomizing chambers 210 may be provided on the atomizing part 200.

In other embodiments, only one overgas passage 130 and one nebulization chamber 210 may be provided.

In other embodiments, the number of the air passing channels 130 and the atomizing chambers 210 may be multiple.

For example, in the embodiment shown in fig. 6, 7 and 8, the heating element 400 is buried in the atomizing area 200 and is located between the gas passing passage 130 and the atomizing chamber 210. This is considered to be that the heat generating element 400 is buried in the wall body of the atomizing area 200 surrounding the side peripheral wall forming the atomizing chamber 210, that is, the heat generating element 400 is not exposed to the gas passing passage 130 and the atomizing chamber 210, and at this time, the inner peripheral surface of the atomizing chamber 210 and the outer peripheral surface of the portion of the atomizing area 200 exposed to the gas passing passage 130 are considered to be main atomizing areas, that is, the atomizing chamber 210 and the gas passing passage 130 are both main atomizing passages.

In some embodiments, as shown in fig. 9, the heating body 400 is at least partially exposed within the overgas passage 130. For example, the heat generating body 400 protrudes into the gas passing passage 130 but does not contact the inner peripheral surface of the gas passing passage 130. For another example, the heating element 400 is laid on the inner peripheral surface of the gas passing passage 130. For another example, the heating element 400 is embedded in the inner circumferential surface of the gas passing channel 130, that is, only a part of the heating element 400 is located on the inner circumferential surface of the gas passing channel 130, and only a part of the heating element 400 is exposed in the gas passing channel 130. In such embodiments, the overgas passage 130 may be considered as the primary atomizing area.

In some embodiments, the heat-generating body 400 is at least partially exposed within the nebulizing chamber 210. For example, the heat generating body 400 protrudes into the atomizing chamber 210 but does not contact the inner circumferential surface of the atomizing chamber 210. For another example, the heating body 400 is laid on the inner circumferential surface of the atomizing chamber 210. For another example, the heating element 400 is embedded in the inner peripheral surface of the atomizing chamber 210, that is, only a part of the heating element 400 is located above the inner peripheral surface of the atomizing chamber 210, and only a part of the heating element 400 is exposed in the atomizing chamber 210. In such embodiments, the nebulization chamber 210 may be considered as the primary nebulization region.

Referring to fig. 1, 2, 5, 6, 10, 11, 14 and 15, in some embodiments, a material guiding portion 220 is further disposed on a side of the atomizing portion 200 facing the feeding hole 120, which may be considered as that the outer circumferential surface of the atomizing portion 200 protrudes outwards in a radial direction to form the material guiding portion 220, and the material guiding portion 220 faces the feeding hole 120, and the material guiding portion 220 is embedded in the feeding hole 120 and covers the whole feeding hole 120, and the material guiding portion 220 is used for contacting with the atomized medium and transmitting the atomized medium to the atomizing portion 200. Both the material guiding part 220 and the atomizing part 200 are made of porous materials with certain porosity, the porosity of the material guiding part 220 is higher than that of the atomizing part 200, the atomizing part 200 and the material guiding part 220 made of porous materials are in a porous shape at a microscopic level, and atomized media such as tobacco tar can be transported in the atomized media by capillary action. On the one hand, since the porosity of the material guiding portion 220 is higher, the speed of the material guiding portion 220 absorbing and conducting the atomized medium is faster, that is, the material guiding portion 220 can increase the speed of the atomized medium transferred to the atomized portion 200, so as to avoid the dry burning of the atomized portion 200 due to insufficient atomized medium; on the other hand, if the porosity of the atomizing part 200 is low, the conduction rate of the atomizing medium in the atomizing part 200 is reduced, so that the condition that the atomizing medium is too fast transferred into the atomizing cavity 210 to leak liquid, block the atomizing cavity and the like can be avoided.

More specifically, as shown in fig. 2 and 6, in an embodiment, a side of the guide portion 220 facing away from the atomizing portion 200 is flush with an outer circumferential surface of the support portion 100. In another embodiment, as shown in fig. 10 and 11, the thickness of the guide part 220 may be smaller than the thickness of the side circumferential wall of the support part 100. In another embodiment, as shown in fig. 14 and 15, an end of the guiding portion 220 away from the supporting portion 100 protrudes from the outer peripheral surface of the supporting portion 100.

Referring to fig. 12 and 13, in some embodiments, the atomizing assembly 11 further includes an atomizing sleeve 300 sleeved on the outer peripheral surface of the supporting portion 100, and a through hole 310 is disposed on a side peripheral wall of the atomizing sleeve 300, the through hole 310 is in communication with the feeding hole 120, and the through hole 310 is used for allowing an atomizing medium to enter the feeding hole 120 to contact with the atomizing portion 200.

Further, as shown in fig. 14, 15, 16, 17 and 18, in some embodiments, the guiding portion 220 is disposed through the feeding hole 120, and the guiding portion 220 at least partially protrudes into the through hole 310. The atomizing part 200 is connected with the material guiding part 220, and the material guiding part 220 passes through the feeding hole 120 and stretches into the through hole 310 of the atomizing sleeve 300, so that the atomizing part 200 can be matched and connected with the atomizing sleeve 300 through the material guiding part 220, the tightness and the firmness of the atomizing sleeve 300, the supporting part 100 and the atomizing part 200 are enhanced, the loosening is not easy, and meanwhile, the assembly is easier.

For example, as shown in fig. 16, in some embodiments, the material guiding portion 220 does not protrude from the outer circumferential surface of the atomizing sleeve 300, and the thickness of the material guiding portion 220 is smaller than the sum of the thicknesses of the supporting portion 100 and the atomizing sleeve 300.

As another example, as shown in fig. 17, in some of the embodiments, a side of the guide portion 220 facing away from the atomizing portion 200 is flush with an outer circumferential surface of the atomizing sleeve 300.

As another example, as shown in fig. 18, in some of the embodiments, an end of the guide portion 220 remote from the atomizing portion 200 protrudes from the outer circumferential surface of the atomizing sleeve 300. When the outer peripheral surface of the atomizing sleeve 300 is filled with the atomizing medium, such as the storage bin storing the atomizing medium is disposed near the through hole 310 on the outer side of the atomizing sleeve 300, the guide portion 220 protruding out of the atomizing sleeve 300 is equivalent to directly extending into the atomizing medium, so that the contact area between the guide portion 220 and the atomizing medium can be increased, and the speed of the guide portion 220 for absorbing and conveying the atomizing medium can be increased.

In some of these embodiments, the pilot 220 fills the entire feed hole 120 in the cross-section of the feed hole 120, i.e., the pilot 220 obscures the entire feed hole 120.

It is understood that the number of the feed holes and the guide portions 220 is not limited in this application.

For example, in some embodiments, the feed aperture 120 and the pilot 220 may each be provided as one.

As another example, in other embodiments, the feeding holes 120 and the guiding portions 220 may be provided in plural numbers, and the guiding portions 220 correspond to the feeding holes 120 in number and position one by one. More specifically, as shown in the embodiment of fig. 9, 10 and 11, two sides of the atomizing sleeve 300 are respectively provided with one feeding hole 120, and correspondingly, two sides of the atomizing part 200 are respectively protruded to form one guiding part 220, wherein one guiding part 220 extends into one feeding hole 120, and the other guiding part 220 extends into the other feeding hole 120.

Referring to fig. 4, in some embodiments, the inner circumferential surface of the hollow tube 110 is provided with a barrier layer 140 for inhibiting the transmission of the atomized medium. For example, the barrier layer 140 may be formed by sintering a porous material with low porosity or a non-porous material on the inner circumferential surface of the hollow pipe 110. As another example, the barrier layer 140 may be a liquid impermeable metal tube, an inorganic nonmetallic tube. For another example, the barrier layer 140 may also be a coating having hydrophobic and oleophobic properties, or the like.

In addition, as shown in fig. 19, the present application further relates to an atomizing device 10, which includes a main body 12, a storage cavity, and an atomizing assembly 11 according to any of the foregoing embodiments, wherein the storage cavity is disposed in the main body 12, and is configured to store an atomizing medium and convey the atomizing medium to the atomizing portion 200 through the feed hole 120.

Specifically, as shown in fig. 19, in some of these embodiments, the atomizing device 10 further includes a sensing element 13 disposed within the main body 12, the main body 12 being formed with an air inlet 121 and an air outlet 122; one end of the atomizing chamber 210 is communicated with the air inlet 121, the other end of the atomizing chamber 210 is communicated with the air outlet 122, one end of the air passing channel 130 is communicated with the air inlet 121, the other end of the air passing channel 130 is communicated with the air outlet 122, and the sensing element 13 is used for detecting air flow change of an air flow path between the air inlet 121 and the air outlet 122. The sensing element 13 may be a microphone, etc., and the sensing element 13 may detect a change in airflow, for example, the atomizing chamber 210 is in a conducting state with at least one of the air passing channels 130, when the user sucks from the air outlet 122, a negative pressure occurs on a side of the sensing element 13 near the air outlet 122, and the sensing element 13 may send a signal to start the atomizing device 10 to start working, so as to generate aerosol.

More specifically, as shown in fig. 19, in some embodiments, the sensing element 13 may be disposed between the air outlet 122 and the atomizing assembly 11. In other embodiments, the sensing element 13 may also be disposed between the air inlet 121 and the atomizing assembly 11. As long as the atomizing assembly 11 is not blocked, i.e. at least one of the overair channel 130 and the atomizing chamber 210 is in a conducting state, the sensing element 13 can work normally, so as to drive the heating element 400 of the atomizing assembly 11 to work.

In addition, as shown in fig. 19, the present application also relates to an aerosol-generating device, which includes a power supply device 20 and the atomizing device 10 according to any one of the above embodiments, wherein the power supply device 20 is electrically connected to the heating element 400 to enable the heating element 400 to generate heat.

The above-mentioned atomizing device 10 and the aerosol-generating apparatus may be provided with the atomizing assembly 11 according to the above-mentioned embodiments, and therefore, the following advantages are at least included:

first, the atomized medium may contact the atomizing part 200 through the feed hole 120, and the atomizing part 200 may transfer the atomized medium therein, and a part of the atomized medium may be transferred into the gas passing channel 130 and atomized in the gas passing channel 130 to form aerosol for suction. It should be emphasized that the air passage 130 is formed by enclosing the atomizing unit 200 with the inner peripheral surface 111 of the hollow tube 110 of the support unit 100, that is, a part of the air passage 130 is the atomizing unit 200, and a part of the air passage 130 is the support unit 100, so that only a part of the outer peripheral surface of the atomizing unit 200 transmits the atomized medium into the air passage 130, while the support unit 100 can inhibit the transmission of the atomized medium from the outer wall surface of the support unit 100 or the inside of the support unit 100 to the inner peripheral surface of the hollow tube 110, in particular, inhibit the transmission of the atomized medium to the support unit 100 of the hollow tube, so that the air passage 130 is prevented from being blocked due to excessively high introducing amount of the atomized medium in the air passage 130 per unit time, and the possibility that the liquid drops in the tube inner periphery of the air passage 130 are converged due to surface tension to form a liquid film to block the air passage 130 is reduced, thereby ensuring the conduction of the air passage 130. In this way, when the user sucks, the relevant equipment can always detect the change of the air flow through the air passage 130, and when the change of the air flow is detected, the atomization assembly 11 can normally start to work;
