Description

Technical Field

[0001] This invention belongs to the technical field of atomizing devices, and particularly relates to an atomizer and an electronic atomizing device. Background Technology

[0002] An electronic atomizing device is a device that generates aerosols for user consumption through heating and atomization. The device stores an edible aerosol-generating matrix in a reservoir within the atomizer, and then heats and atomizes the matrix into an edible aerosol using an atomizing component. In related technologies, the atomizing component introduces the aerosol-generating matrix into the reservoir through a liquid guide and exits the aerosol through an airflow channel.

[0003] However, the liquid guiding section is small in size and has limited liquid retention capacity, and the flow rate of the aerosol generating matrix input into the liquid guiding section is not constant. For example, as the atomizing component heats up during use, the temperature in the liquid storage chamber rises, generating greater pressure. The liquid storage chamber tends to supply more aerosol generating matrix into the liquid guiding section. When the liquid guiding section is insufficient to absorb all the input aerosol generating matrix, the excess matrix leaks, affecting the user experience. Summary of the Invention

[0004] In view of this, the present invention provides an atomizer and an electronic atomizing device to solve the technical problem of how to reduce the possibility of leakage of the atomizing component.

[0005] To solve the above problems, the technical solution provided by the embodiments of the present invention is as follows:

[0006] An atomizer includes: a housing having a spaced-apart liquid storage chamber and a temporary storage chamber, both of which are used to store an aerosol generating matrix; an atomizing assembly having an internal airflow channel; the atomizing assembly including a liquid section and a heating element connected to the liquid guiding section, the liquid guiding section being used to input the aerosol generating matrix and disposed within the airflow channel, the liquid guiding section communicating with the liquid storage chamber and spaced apart from the temporary storage chamber; and a liquid guide having a capillary channel, the liquid guide contacting the liquid guiding section, the aerosol generating matrix reciprocating between the liquid guiding section and the temporary storage chamber via the capillary channel.

[0007] In some embodiments, the liquid guide is further provided with a central air channel, which is spaced apart from the capillary channel and communicates with the airflow channel. Both the capillary channel and the central air channel extend from a first end of the liquid guide to a second end of the liquid guide. The first end contacts the liquid guide portion, the second end extends into the temporary storage cavity, and the airflow channel discharges the aerosol in a direction from the second end to the first end.

[0008] In some embodiments, the cross-sectional area of ​​the capillary channel is reduced along the direction from the first end to the second end.

[0009] In some embodiments, the outer wall of the liquid guide is provided with at least one drainage groove, and each drainage groove forms the capillary channel.

[0010] In some embodiments, the depth of the drainage groove is greater than or equal to 0.2 mm and less than or equal to 0.6 mm in the diametrical direction of the central airway; and / or, the width of the drainage groove is greater than or equal to 0.1 mm and less than or equal to 0.6 mm.

[0011] In some embodiments, the liquid guide includes a plurality of fins extending along the extension direction of the central air passage, the fins being parallel to each other and spaced apart, and a flow channel being formed between two adjacent fins; wherein the first end and the second end are the opposite ends of the fins along the extension direction of the central air passage.

[0012] In some embodiments, the liquid guiding portion includes a drainage section adjacent to the liquid guiding portion, wherein the cross-sectional area of ​​the capillary channel decreases from the direction close to the liquid guiding portion to the direction away from the liquid guiding portion.

[0013] In some embodiments, the atomizing assembly further includes: an atomizing tube installed inside the housing, with the liquid storage chamber formed between the atomizing tube and the housing, and the atomizing tube forming the airflow channel; wherein the liquid guiding part and the liquid guiding part are both installed inside the atomizing tube.

[0014] This invention also provides an electronic atomizing device, which includes the aforementioned atomizer and a power supply for supplying power to the atomizer.

[0015] This invention provides an atomizer and an electronic atomizing device. The electronic atomizing device includes an atomizer and a power supply, the power supply being used to power the atomizer. The atomizer includes a housing, an atomizing component, and a liquid guide. The housing has a spaced-apart reservoir and a temporary storage chamber, both used to store aerosol generation matrix. An airflow channel for aerosol circulation is formed inside the atomizing component. The atomizing component includes a liquid guide portion for absorbing the aerosol generation matrix, and a heating element connected to the liquid guide portion. The liquid guide portion is disposed within the airflow channel. The liquid guide portion communicates with the reservoir and is spaced apart from the temporary storage chamber, allowing the liquid guide portion to receive the aerosol generation matrix flowing out of the reservoir. The liquid guide portion has capillary channels, contacting the liquid guide portion, and the aerosol generation matrix reciprocates between the liquid guide portion and the temporary storage chamber via the capillary channels. This design allows for efficient flow of aerosol generation matrix. When the storage chamber is under high pressure and an excessive amount of matrix is ​​supplied to the liquid guide section, the leaked liquid extruded from the guide section can be guided into the temporary storage chamber via capillary channels. This reduces the possibility of leaked liquid accumulating at the guide section and forming a liquid column, as well as the possibility of leaked liquid entering the airflow channel. The atomizer is less prone to leakage, thus improving the user experience. Furthermore, as the matrix on the guide section is consumed, it can absorb leaked liquid from the temporary storage chamber for reuse, resulting in a high utilization rate of the matrix.

It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the directions under normal use, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use.

[0030] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0031] This invention provides an atomizer 10 and an electronic atomization device. The electronic atomization device includes an atomizer 10, which stores an aerosol-generating matrix. The atomizer 10 is used to atomize the aerosol-generating matrix into an aerosol. The aerosol-generating matrix includes, but is not limited to, e-liquid, chemical liquids, and plant sap. The atomizer 10 can be applied in medical, beauty, and electronic aerosolization scenarios. It should be noted that the application scenario type of this invention does not limit the structure of the atomizer 10 and the electronic atomization device.

[0032] like Figures 1-4 As shown, this invention provides an atomizer 10, which includes a housing 1, an atomizing component 2, and a liquid guide 3. The housing 1 has a spaced-apart storage chamber 11 and a temporary storage chamber 12, both used to store aerosol generating matrix. When the atomizer 10 is just filled with aerosol generating matrix, the aerosol generating matrix is ​​preferentially stored in the storage chamber 11. An airflow channel 21 is formed inside the atomizing component 2 to allow aerosol flow. The atomizing component 2 includes a liquid guide portion 22 disposed within the airflow channel 21 and a heating element 23 connected to the liquid guide portion 22. The extending direction of the liquid guide portion 22 is the same as the extending direction of the airflow channel 21, which can be simply understood as the liquid guide portion 22 being placed longitudinally relative to the airflow channel 21. The liquid guide portion 22 communicates with the storage chamber 11 to input the aerosol generating matrix into the storage chamber 11, that is, the liquid guide portion 22 itself has the functions of guiding and locking liquid.

[0033] Specifically, such as Figure 3 As shown, the liquid guiding part 22 can generally be porous ceramic or oil-retaining cotton, which can be used to adsorb and store the aerosol generating matrix. The liquid guiding part 22 can be a hollow component or a solid component that has both adsorption and liquid guiding functions. It is understood that the heating element 23 can heat and atomize the aerosol generating matrix into aerosol. The heating element 23 can be a heating wire, heating film, or mesh coil. The heating element 23 can be located outside the liquid guiding part 22, or inside the liquid guiding part 22 when the liquid guiding part 22 is hollow. This application does not limit the specific positions of the liquid guiding part 22 and the heating element 23, as long as the heating element 23 is connected to the liquid guiding part 22. When current passes through the heating element 23, the heating element 23 generates heat, based on the principle of the electro-effect. The heat is transferred to the liquid guiding part 22, causing the liquid guiding part 22 to heat up, thereby atomizing the aerosol generating matrix in the liquid guiding part 22 into aerosol, based on the principle of the thermal effect. In the embodiment shown in the schematic diagram of this application, the liquid guiding part 22 is hollow, and the inner wall of the liquid guiding part 22 forms an atomizing cavity 221 that communicates with the airflow channel 21. The heating element 23 is disposed in the atomizing cavity 221, and the aerosol is generated in the atomizing cavity 221 and diffuses into the airflow channel 21.

[0034] As the background technology indicates, based on the gas law, under the same conditions, temperature and pressure are positively correlated. When an electronic atomizing device moves from a low-temperature environment to a high-temperature environment, or after continuous heating by the heating element, the temperature of the liquid storage chamber increases. The gas in the liquid storage chamber expands, forcing the aerosol generation matrix through the liquid guide. However, the liquid guide, limited by its own volume, has limited liquid-locking capacity. When the liquid guide is insufficient to absorb all the aerosol generation matrix squeezed out from the liquid storage chamber, some aerosol generation matrix will seep out, resulting in leakage. This leakage easily accumulates at the liquid guide, forming a liquid column, which then causes leakage when the user obtains the aerosol. Leakage can also easily seep into the airflow channel and then flow out of the atomizer, affecting the user's taste and experience of obtaining the aerosol.

[0035] like Figure 3 As shown, in this embodiment of the invention, the liquid guiding section 22 is spaced apart from the temporary storage chamber 12. Therefore, when the pressure of the liquid guiding section 22 and the liquid storage chamber 11 is balanced, the aerosol generation matrix preferentially flows to the liquid guiding section 22. The liquid guiding section 3 is provided with capillary channels 31 (see reference). Figure 5 The liquid guide 3 contacts the liquid guide section 22, and the liquid guide 3 guides the aerosol generating matrix to move between the liquid guide section 22 and the temporary storage chamber 12 through the capillary channel 31. When the liquid storage chamber 11 is under high pressure and an excessive amount of aerosol generating matrix is ​​supplied to the liquid guide section 22, the leaked liquid squeezed out from the liquid guide section 22 can be guided into the temporary storage chamber 12 for storage through the capillary channel 31, reducing the possibility of the leaked liquid accumulating at the liquid guide section 22 to form a liquid column, and also reducing the possibility of the leaked liquid flowing into the airflow channel 21, thereby reducing the possibility of the atomizer 10 sucking up the liquid.

[0036] It is understandable that capillary action occurs at the liquid guiding section 22 and the liquid guiding section 3, respectively, in the aerosol generating matrix. Capillary action, also known as capillary phenomenon, refers to the phenomenon where a liquid rises or falls within a narrow tubular object due to the difference between cohesive and adhesive forces. Simply put, the micropores in the liquid guiding section 22 and the capillary channels 31 in the liquid guiding section 3 can both generate attractive forces that cause the aerosol generating matrix to flow.

[0037] like Figure 3As shown, to facilitate understanding of the flow process of the aerosol generating matrix between the liquid guiding section 22 and the temporary storage chamber 12, it is assumed that the atomizer 10 is in a set scenario. In this set scenario, the pressure in the liquid storage chamber 11 is continuously high, meaning that the liquid storage chamber 11 continuously supplies an excessive amount of aerosol generating matrix to the liquid guiding section 22. At this time, the micropores on the liquid guiding section 22 are not empty, so the liquid guiding section 22 continuously expels liquid, which flows into the temporary storage chamber 12 under the attraction of the capillary channel 31. When the user inhales aerosol, the aerosol generating matrix on the liquid guiding section 22 is consumed with the user's use, and some of the micropores on the liquid guiding section 22 become empty. The liquid in the temporary storage chamber 12 flows back into the liquid guiding section 22 through the capillary channel 31. In other words, under the set scenario and when the user uses the atomizer 10 to obtain aerosol, the aerosol generating matrix can flow back and forth between the liquid storage chamber 11 and the temporary storage chamber 12 through the capillary channel 31, and the temporary storage chamber 12 dynamically stores liquid. Understandably, under normal usage scenarios, the capillary channel 31 can balance the pressure between the liquid storage chamber 11 and the liquid guiding part 22. Furthermore, with the use of the aerosol generation matrix, the possibility of the pressure in the liquid storage chamber 11 being under continuous high pressure is relatively small. Therefore, under normal circumstances, the volume of leakage is smaller than the volume of the temporary storage chamber 12.

[0038] An atomizer 10 provided in this embodiment of the invention includes a housing 1, an atomizing component 2, and a liquid guide 3. The housing 1 has a spaced-apart storage chamber 11 and a temporary storage chamber 12, both used to store aerosol generation matrix. An airflow channel 21 is formed inside the atomizing component 2 for the flow of aerosols and external atmosphere. The atomizing component 2 includes a liquid guide section 22 for absorbing the aerosol generation matrix, and a heating element 23 connected to the liquid guide section 22. The liquid guide section 22 is coaxially disposed within the airflow channel 21. The liquid guide section 22 communicates with the storage chamber 11 and is spaced apart from the temporary storage chamber 12. The liquid guide section 22 can receive the aerosol generation matrix flowing out of the storage chamber 11. When the pressure of the liquid guide section 22 and the storage chamber 11 is balanced, the aerosol generation matrix will not flow into the temporary storage chamber 12, which is spaced apart from the liquid guide section 22. The liquid guide 3 has a capillary channel 31, which contacts the liquid guide section 22. The aerosol generating matrix moves back and forth between the liquid guide section 22 and the temporary storage chamber 12 via the capillary channel 31. When the temperature of the liquid storage chamber 11 rises and it has high pressure, the liquid storage chamber 11 supplies an excessive amount of aerosol generating matrix to the liquid guide section 22. The liquid guide section 22 has limited liquid retention capacity and is insufficient to absorb all the aerosol generating matrix flowing out of the liquid storage chamber 11. Some of the aerosol generating matrix is ​​squeezed out of the liquid guide section 22, forming leakage. The leakage can be guided into the temporary storage chamber 12 for storage via the capillary channel 31, reducing the possibility of leakage accumulating at the liquid guide section 22 and forming a liquid column, which could generate noise when the user obtains aerosol. It also reduces the possibility of leakage into the airflow channel 21 and flowing out of the atomizer 10 via the airflow channel 21. The possibility of leakage in the atomizer 10 is relatively small. As the aerosol generation matrix on the liquid guiding section 22 is consumed, the liquid guiding section 22 can absorb the leakage in the temporary storage chamber 12. The leakage can be atomized into aerosol at the liquid guiding section 22, which improves the utilization rate of the atomizer 10 of the aerosol generation matrix.

[0039] In some embodiments, such as Figure 3 As shown, the cross-sectional area of ​​the flow channel in the liquid guiding section 22 used for inputting the aerosol generating matrix is ​​smaller than that of the capillary channel 31. In other words, the pore size of the micropores in the liquid guiding section 22 is smaller than the cross-sectional area of ​​the capillary channel 31. Based on the formula for the height of liquid rise or fall in capillary action, it is known that the height of liquid rise or fall is negatively correlated with the diameter of the component inserted into the liquid. This can be simply understood as the liquid generating a larger capillary effect at components with smaller diameters. In other words, the capillary force generated by the aerosol generating matrix at the micropores of the liquid guiding section is greater than the capillary force generated in the capillary channel. This can be simply understood as the attraction of the liquid guiding section 22 to the aerosol generating matrix being greater than the attraction of the capillary channel 31 to the aerosol generating matrix.

[0040] Specifically, such as Figure 3As shown, since the liquid-conducting part 22 itself can lock in liquid, it can be understood that the liquid-conducting part 22 is made of porous material. That is, the pore size of the micropores in the liquid-conducting part 22 is on the micrometer scale, and the average pore size of the micropores can be in the range of 20μm to 55μm. For example, the specific value of the pore size is 20μm, 30μm, 45μm, or 55μm, or any other value within the above range. It should be noted that although the aerosol generating matrix can generate capillary action at both the liquid-conducting part 22 and the liquid-conducting part 3, the liquid-conducting part 22 is different from the liquid-conducting part 3. The liquid-conducting part 22 generates capillary action in the aerosol generating matrix through the micropores of the material itself, while the liquid-conducting part 3 generates capillary action in the aerosol generating matrix through the additional capillary channels 31. As the aerosol generating matrix on the liquid guiding section 22 is consumed, the liquid guiding section 22 can absorb the leakage in the temporary storage chamber 12. The leakage into the temporary storage chamber 12 can flow back into the liquid guiding section 22 through the capillary channel 31 and be atomized into aerosol at the liquid guiding section 22. The utilization rate of the aerosol generating matrix is ​​high, which allows the atomizer 10 to consume the aerosol generating matrix more fully, which is conducive to saving energy and can also reduce the frequency of users replacing and / or replenishing the aerosol generating matrix.

[0041] In some embodiments, such as Figure 3 and Figure 5 As shown, the liquid guide 3 also has a central air channel 32 spaced apart from the capillary channel 31. The central air channel 32 is connected to the airflow channel 21. It can be understood that when the liquid guide portion 22 is hollow and forms an atomizing chamber 221, the central air channel 32 is connected to the airflow channel 21 via the atomizing chamber 221. Both the capillary channel 31 and the central air channel 32 extend from the first end 33 of the liquid guide 3 to the second end 34 of the liquid guide 3 (see reference). Figure 5 The first end 33 and the second end 34 are opposite ends in the direction of liquid 3 extension, and the airflow channel 21 discharges aerosol along the direction from the second end 34 to the first end 33. That is to say, the direction from the second end 34 to the first end 33 is the direction of aerosol discharge, and also the direction of gas flow in the airflow channel 21. Figure 3 In this design, the first end 33 can be simply understood as the upper end of the liquid guide 3, and the second end 34 as the lower end of the liquid guide 3. The first end 33 contacts the liquid guide section 22, and the second end 34 extends into the temporary storage chamber 12. The liquid squeezed out from the liquid guide section 22 flows from the first end 33 to the second end 34 and enters the temporary storage chamber 12. That is, the liquid squeezed out from the liquid guide section 22 flows in a downward direction, while the aerosol flows in a downward direction within the liquid guide section 22. The central air channel 32 and the capillary channel 31 are separated, making the gas flow path and liquid flow path on the liquid guide 3 independent. The atmospheric air supplied to the liquid guide section 22 by the central air channel 32 carries the aerosol into the airflow channel 21, and then out of the atomizer 10 via the airflow channel 21. (Refer to...) Figure 5The capillary channel 31 can be a through groove formed on the outer wall of the liquid guide 3, with an open peripheral wall; or it can be a through hole surrounding the central air passage 32, with a closed peripheral wall. Regardless of how the capillary channel 31 is configured, it is always separated from the central air passage 32. The leaked liquid flows within the capillary channel 31, while atmospheric air circulates within the central air passage 32, reducing the possibility of leaked liquid entering the central air passage 32 through the capillary channel 31 and improving the user experience.

[0042] In some embodiments, such as Figure 5 As shown, along the direction from the first end 33 to the second end 34, the cross-sectional area of ​​the capillary channel 31 decreases, meaning that the capillary force generated by the aerosol generating matrix at the capillary channel 31 increases from top to bottom. This can be simply understood as the increased attraction of the guiding liquid 3 to the aerosol generating matrix from top to bottom, allowing the leaked liquid squeezed from the guiding liquid section 22 to accumulate at the lower end of the guiding liquid 3. In other words, the lower end of the guiding liquid 3, where the attraction is greater, can lock in the liquid, facilitating its storage at the second end 34 (lower end) of the guiding liquid 3 and / or within the temporary storage chamber 12. This keeps the leaked liquid away from the guiding liquid section 22, reducing the possibility of it accumulating at the guiding liquid section 22 and forming a liquid column, thereby reducing the likelihood of the atomizer 10 sucking up leaked liquid.

[0043] In some embodiments, such as Figure 5 As shown, at least one drainage groove 35 is provided on the outer wall of the liquid guide 3, and the drainage grooves 35 together form a capillary channel 31. Compared with the embodiment of setting through holes to form a capillary channel 31, the drainage groove 35 has a groove-shaped structure with an open peripheral wall, which provides a larger operating space and is easier to machine.

[0044] Specifically, such as Figure 3 and Figure 5 As shown, when a drainage groove 35 is formed on the outer wall of the liquid guide 3, the processing steps of the capillary channel 31 are simplified, making it easier to form the liquid guide 3. When multiple drainage grooves 35 are formed on the outer wall of the liquid guide 3, each drainage groove 35 guides the leakage flow at multiple positions, and the capillary channel 31 can guide a larger leakage flow rate per unit time, with higher timeliness. This facilitates the rapid flow of leakage from the liquid guide section 22 to the temporary storage chamber 12, and also facilitates the rapid flow of leakage from the temporary storage chamber 12 to the liquid guide section 22.

[0045] In some embodiments, such as Figure 3 and Figure 5 As shown, in the diametrical direction of the central airway 32 ( Figure 5(As shown in the left-right direction), the depth of the drainage groove 35 is greater than or equal to 0.2 mm and less than or equal to 0.6 mm. It can be understood that the depth of the drainage groove 35 represents the radial dimension of the drainage groove 35 in the guiding liquid 3; and / or, the width of the drainage groove 35 is greater than or equal to 0.1 mm and less than or equal to 0.6 mm. It can be understood that the width of the drainage groove 35 represents the spacing between the two side walls forming a single drainage groove 35. Specifically, the depth of the drainage groove 35 can be any other value within the above range, such as 0.2 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.55 mm, 0.6 mm; the width of the drainage groove 35 can be any other value within the above range, such as 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.55 mm, 0.6 mm. Users can set the depth and width of the drainage channel 35 according to actual needs, so that the attraction generated by the drainage channel 35 can guide the leakage at the liquid guide section 22 to the temporary storage chamber 12, and limit the flow rate of leakage supplied by the drainage channel 35 to the temporary storage chamber 12, thereby reducing the possibility of excessive leakage in the temporary storage chamber 12 leaking out of the temporary storage chamber 12 or leaking into the central airway 32.

[0046] In some embodiments, such as Figure 5 As shown, the liquid guide 3 includes multiple fins 36 extending along the extension direction of the central air passage 32, i.e., the fins 36 extend along the axial direction of the liquid guide 3. The first end 33 and the second end 34 are the opposite ends of the fins 36 in the axial direction of the liquid guide 3. The fins 36 are parallel to each other and spaced apart in the circumferential direction of the liquid guide 3, and a drainage groove 35 is formed between two adjacent fins 36. Therefore, the "width of the drainage groove 35" mentioned above refers to the minimum distance between two adjacent fins 36. Multiple fins 36 form multiple drainage grooves 35, and each drainage groove 35 surrounds the circumference of the central air passage 32 to guide the leakage flow at multiple locations, increasing the leakage flow rate that the liquid guide 3 can guide per unit time, thereby improving the timeliness of the leakage flow. (Refer to...) Figure 3 This reduces the possibility that the leakage at the liquid guiding section 22 may not be completely or timely flowing into the liquid guiding section 3, and may leak into the atomization chamber 221 or accumulate into a liquid column; it also reduces the possibility that the leakage in the temporary storage chamber 12 may not be completely or timely flowing into the liquid guiding section 22, thus preventing the user from obtaining aerosol in a timely manner.

[0047] In some embodiments, such as Figure 5 and Figure 6As shown, the liquid guiding 3 includes a drainage section 37 adjacent to the liquid guiding portion 22. Within the drainage section 37, the cross-sectional area of ​​the capillary channel 31 decreases from the direction near the liquid guiding portion 22 to the direction away from the liquid guiding portion 22. It can be understood that the flow channel formed by the capillary channel 31 within the drainage section 37 decreases along the top-to-bottom direction. When the capillary channel 31 is configured as a drainage groove 35, the cross-sectional area of ​​the inner wall of the drainage groove 35 formed by the liquid guiding 3 decreases from the first end 33 to the second end 34. The cross-sectional direction is in the diameter direction of the central air passage 32. That is, the cross-sectional area of ​​the drainage groove 35 within the drainage section 37 decreases from top to bottom. It can be understood that the drainage section 37 is the part of the liquid guiding section 3 that is adjacent to the liquid guiding part 22 and has an inclined sidewall. Specifically, the inclined sidewall of the drainage section 37 forms the inner wall of the drainage channel 35 and expands in diameter in the direction from top to bottom, so as to guide the flow of the leaking liquid by using the slope and expand the flow channel area at the connection position of the drainage channel 35 and the liquid guiding part 22, so as to increase the flow rate of the leaking liquid that the drainage channel 35 can guide at the first end 33, and reduce the possibility of the leaking liquid accumulating at the liquid guiding part 22 to form a liquid column or leaking into the airflow channel 21.

[0048] In some possible implementations, such as Figure 5 and Figure 6 As shown, at the position where the liquid guide 3 contacts the liquid guide section 22, the inner wall of the drainage groove 35 is adjacent to the inner wall of the atomizing chamber 221. That is, at the upper end of the drainage section 37, all the gaps in the liquid guide section 22 are within the drainage groove 35, so that the leakage liquid flowing out from each gap in the liquid guide section 22 can flow into the drainage groove 35, further reducing the possibility of leakage liquid accumulating at the liquid guide section 22 to form a liquid column, or leaking into the airflow channel 21.

[0049] In some embodiments, such as Figure 4 and Figure 7As shown, the housing 1 includes an outer shell 13 and a base 14. One end (upper end) of the outer shell 13 has an air outlet 131, which communicates with the airflow channel 21, allowing aerosols to be discharged outside the atomizer 10 via the air outlet 131. The other end (lower end) of the outer shell 13 forms an open opening 132. The base 14 is located at the opening 132 and includes the aforementioned temporary storage chamber 12. The sidewall of the outer shell 13 and the top wall of the base 14 together form a liquid storage chamber 11. The base 14 has a collection tank 141 and / or a liquid storage element that communicates with the capillary channel 31. Both the collection tank 141 and / or the liquid storage element are located within the temporary storage chamber 12 to absorb the aerosol generation matrix in the capillary channel 31 and define the position of the aerosol generation matrix within the temporary storage chamber 12. Specifically, the liquid storage element can be a liquid storage cotton. The base 14 may only have a collection tank 141, only a liquid storage element, or both a collection tank 141 and a liquid storage element. Regardless of which of the aforementioned embodiments is used, the leakage introduced by the capillary channel 31 is stored in the collection tank 141 and / or the storage device, which defines the position of the leakage in the temporary storage chamber 12.

[0050] For ease of explanation, such as Figure 3 and Figure 7 As shown, assuming that the base 14 is only equipped with a liquid collection tank 141 (refer to...) Figure 7 Then, the collection tank 141 is connected to the capillary channel 31. Figure 7 In the schematic diagram shown, the base 14 has multiple ribs at the bottom of the temporary storage chamber 12. The ribs are parallel and spaced apart, and a liquid collection groove 141 is formed between two ribs. The side walls of the ribs form the groove walls of the liquid collection groove 141, and the liquid collection grooves 141 are interconnected. When the aerosol generating matrix comes into contact with the groove wall of the liquid collection groove 141, due to the attraction between liquid molecules and the surface tension, the liquid molecules of the aerosol generating matrix arrange themselves on the surface of the groove wall of the liquid collection groove 141 to form a thin film (i.e., a liquid film). The spacing between two adjacent ribs is small, and the adhesion between the aerosol generating matrix and the groove wall surface of the liquid collection groove 141 also keeps the aerosol generating matrix within the liquid collection groove 141, reducing the possibility of leakage flowing arbitrarily within the temporary storage chamber 12 and leaking out of the atomizer 10 or into the central air channel 32.

[0051] It should be noted that, Figure 3 and Figure 7 All Figure 2 A sectional view, but Figure 3 and Figure 6 In different sectional views, Figure 3 for Figure 2 Sectional view along the AA direction. Figure 7 for Figure 2 A cross-sectional view along the CC direction, where the AA direction is perpendicular to the CC direction.

[0052] In some embodiments, such as Figure 7 As shown in the figure, the base 14 includes a mounting part 142 and a liquid storage part 143. The atomizing component 2 is mounted on the mounting part 142, and the liquid storage part 143 forms a temporary storage chamber 12. The liquid 3 extends into the temporary storage chamber 12 through the mounting part 142. That is, the mounting part 142 is located above the temporary storage chamber 12 and is connected to the atomizing component 2. The temporary storage chamber 12 is formed inside the base 14 and has a relatively closed profile. It can be understood that the liquid storage chamber 11 is formed on the top wall of the mounting part 142, and the temporary storage chamber 12 is formed on the bottom wall of the mounting part 142. As long as a sealing structure is set at the connection between the mounting part 142 and the atomizing component 2, the liquid storage chamber 11 and the temporary storage chamber 12 can be separated. That is, under normal use, the aerosol generation matrix in the liquid storage chamber 11 is not likely to flow directly into the temporary storage chamber 12. The structure is simple and easy to set up a sealing structure.

[0053] In some embodiments, such as Figure 7 and Figure 8 As shown, the atomizing assembly 2 includes an atomizing tube 24, a liquid guiding section 22, and a heating element 23. Both the liquid guiding section 22 and the liquid guiding 3 are installed inside the atomizing tube 24. The air outlet 131 is located above the liquid guiding section 22, and the liquid guiding section 22 is located above the liquid guiding 3. (Refer to...) Figure 6 As shown by the solid arrow, the liquid guide 3 flows through the capillary channel 31 in a downward direction, guiding the leakage at the liquid guide section 22 into the temporary storage chamber 12; (Refer to...) Figure 7 As shown by the dashed arrow, the liquid guide 3 is guided by the central air passage 32 in an upward direction, flowing into the atomizing chamber 221. The airflow generated in the atomizing chamber 221 flows upward to the air outlet 131 and is then discharged through the air outlet 131. The atomizing tube 24 simultaneously forms the mounting base for the liquid guide section 22 and the liquid guide 3. The liquid guide 3 can be installed at the same time as the liquid guide section 22, without the need for additional components for installing the liquid guide 3. This simplifies the assembly difficulty of the liquid guide 3 and reduces the difficulty of arranging the internal parts of the atomizing assembly 2.

[0054] In some embodiments, such as Figure 7 and Figure 8As shown, the atomizing tube 24 includes a first atomizing tube 241 and a second atomizing tube 242. The first atomizing tube 241 has a first through hole 2411 communicating with the liquid storage chamber 11. The second atomizing tube 242 is disposed inside the first atomizing tube 241 and has a second through hole 2421 communicating with the first through hole 2411. The liquid guiding part 22 and the liquid guiding part 3 are both snapped into the second atomizing tube 242, and the liquid guiding part 22 is disposed at the second through hole 2421. That is to say, the atomizing assembly 2 separates the airflow channel 21 and the liquid storage chamber 11 through the first atomizing tube 241, and installs the liquid guiding part 22 and the liquid guiding part 3 through the second atomizing tube 242. The atomizing assembly 2 also includes a liquid suction element 25 disposed between the first atomizing tube 241 and the second atomizing tube 242. The liquid suction element 25 has liquid guiding and liquid locking functions. The liquid suction element 25 is used to transfer the aerosol generating matrix to the liquid guiding part 22, so that the aerosol generating matrix in the liquid storage chamber 11 can be consumed more fully by capillary action. It also reduces the possibility of the aerosol generating matrix leaking into the airflow channel 21 due to pressure fluctuations in the liquid storage chamber 11.

[0055] In some possible implementations, a longer second atomizing tube 242 can be provided so that the inner wall of the second atomizing tube 242 forms an airflow channel 21, which separates the liquid-absorbing element 25 and the airflow channel 21. Alternatively, as shown in the schematic diagram of this application, a shorter second atomizing tube 242 can be provided, with part of the inner wall of the liquid-absorbing element 25 forming the airflow channel 21. It can be understood that the second atomizing tube 242 supports and restricts the position of the liquid-guiding part 22 and the liquid-guiding part 3. Therefore, the structural strength of the second atomizing tube 242 is greater than that of the liquid-absorbing element 25. For example, the second atomizing tube 242 can be made of metal tubing. Reducing the length of the second atomizing tube 242 helps to reduce the weight of the atomizing assembly 2, making it more convenient for the user.

[0056] In some embodiments, such as Figure 7 As shown, the liquid storage section 143 includes a first end face 1431 and an air inlet channel. The air inlet extends through the first end face 1431, which is formed within the temporary storage cavity 12 and away from the liquid guiding section 22. That is, the first end face 1431 forms the bottom surface of the temporary storage cavity 12. The air inlet 1432 connects the atmospheric environment with the temporary storage cavity 12. The air inlet 1432 is used to supply atmospheric air to the central air passage 32.

[0057] Specifically, in some possible implementations, the air inlet 1432 extends into the central air passage 32, that is, the air inlet 1432 is a perforated channel with a certain depth. The perforated channel is coaxially arranged with the central air passage 32 and extends longitudinally within the central air passage 32. The wall of the air inlet 1432 can be used to separate the liquid flow path and the gas flow path, reducing the possibility of liquid leakage into the central air passage 32 or flowing out of the atomizer 10 through the air inlet 1432.

[0058] In some possible implementations, the second end 34 contacts the first end face 1431, which forms a limiting surface for the fluid guiding 3, restricting the degree of freedom of the fluid guiding 3 and reducing the degree of freedom of the fluid guiding 3. Figure 7 The vertical movement is shown. In this embodiment, the liquid guide 3 has an air inlet channel located adjacent to the second end 34, i.e., the air inlet channel is located at the lower part of the liquid guide 3 in the axial direction, which helps to maintain the structural integrity of the capillary channel 31. The air inlet channel is connected to the central air passage 32 and the air inlet 1432 to supply outside air into the central air passage 32. It should be noted that in this embodiment, some outside air enters the temporary storage chamber 12, but because the aerosol generating matrix generates capillary forces at both the liquid collection tank 141 and the capillary channel 31, and each liquid collection tank 141 is connected to the capillary channel 31, and the capillary channel 31 is connected to the liquid guide part 22, the leakage in each liquid collection tank 141 preferentially flows to the liquid guide part 22 through the capillary channel 31, and is less likely to leave the liquid collection tank 141 and enter the central air passage 32.

[0059] In some possible implementations, such as Figure 7 As shown, the second end 34 is spaced apart from the first end face 1431, and the gap between the second end 34 and the first end face 1431 forms an air intake channel that communicates with the central air passage 32 and the air inlet 1432. That is to say, there is no need to make additional openings or holes on the peripheral wall of the liquid guide 3, the capillary channel 31 maintains structural integrity, which facilitates the flow of the aerosol generation matrix into the liquid collection tank 141 through the capillary channel 31.

[0060] like Figure 9 As shown, this embodiment of the invention also provides an electronic atomizing device, which includes the aforementioned atomizer 10. This electronic atomizing device can be an electronic cigarette, an electronic medical atomizer 10, or an electronic beauty atomizer 10, etc. The electronic atomizing device also includes a power supply 20, which is electrically connected to the atomizing component 2 in the atomizer 10. The power supply 20 supplies power to the atomizer 10 to drive the atomizing component 2 (see reference). Figure 7 ) operates. Specifically, the power supply 20 is located in the liquid storage chamber 11 (refer to...) Figure 3 In addition, the power supply 20 and the heating element 23 (refer to) Figure 7 The device is electrically connected to provide power to the heating element 23 and can control the start / stop of the heating element 23 and control its heating power. This application does not limit the specific type of power source 20; for example, the power source 20 can be a lithium battery. This application protects an electronic atomizing device configured with the aforementioned atomizer 10. Since the electronic atomizing device includes the aforementioned atomizer 10, it has the same technical effects, namely, a lower possibility of leakage, higher utilization rate of the aerosol generation matrix, and lower noise during aerosol acquisition.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
