Description

Technical Field

[0001] The present application relates to the field of atomization technology, and in particular to an atomization component and an electronic atomizer. Background Art

[0002] Aerosol is a colloidal dispersion system formed by small solid or liquid particles dispersed and suspended in a gas medium. Aerosol can be absorbed by the human body through the respiratory system, providing users with a new alternative absorption method. Atomization device refers to a device that forms an aerosol by heating or ultrasound. Atomizable media include liquid, gel, paste or solid aerosol-generating matrices. Atomizing these media can deliver inhalable aerosols to users, replacing conventional product forms and absorption methods.

[0003] Some atomization devices include a heating element for heating the atomized aerosol-generating substrate. However, in order to prevent the heating element from moving after assembly, the gap between the heating element and its limiting structure is very small. Although this effectively prevents the heating element from moving and causing problems such as leakage, it also causes the contact area between the heating element and the aerosol-generating substrate to be too small, which in turn leads to insufficient liquid supply and other phenomena, affecting the normal use of the atomization device. Utility Model Content

[0004] Based on this, it is necessary to provide an atomization component and an electronic atomizer to address the problem of insufficient liquid supply to the heating element.

[0005] An atomizing assembly, comprising:

[0006] The heating cover has a mounting groove and a lower liquid channel connected to one end of the mounting groove;

[0007] a heating element, which is limitedly located in the installation groove, and has a liquid inlet surface facing the lower liquid channel and a side surface surrounding the liquid inlet surface in a circumferential direction; and

[0008] A sealing member, which is limitedly located in the installation groove and at least partially located on a side of the heating element facing the lower liquid channel, and the sealing member is provided with a connecting groove connecting the lower liquid channel and the liquid inlet surface;

[0009] A liquid storage space is formed between the groove wall of the installation groove and the side surface, and the sealing component partially protrudes from the side surface of the heating element and extends into the liquid storage space.

[0010] In one of the embodiments, two liquid storage spaces are formed between the groove wall of the installation groove and the side surface, and the two liquid storage spaces are respectively located on opposite sides of the heating element in the width direction.

[0011] In one embodiment, the length direction of each of the liquid storage spaces is parallel to the length direction of the heating element.

[0012] In one embodiment, the width of the liquid storage space in a direction perpendicular to the side surface is less than 0.5 mm.

[0013] In one embodiment, the width of the liquid storage space in a direction perpendicular to the side surface is 0.2 mm-0.3 mm.

[0014] In one of the embodiments, at least one auxiliary liquid supply groove is formed on the groove wall of the installation groove, and the liquid storage space is formed between the groove wall of the auxiliary liquid supply groove and the side surface.

[0015] In one embodiment, the sealing member is provided with a plurality of protrusions, and all of the protrusions extend into the liquid storage space.

[0016] In one of the embodiments, the sealing member is provided with two protruding portions, and the two protruding portions protrude from opposite sides of the heating element in the width direction.

[0017] In one of the embodiments, the ratio of the width of the portion of the groove wall of the connecting groove where the protrusion is provided to the height of the groove wall of the connecting groove is greater than 1.

[0018] An electronic atomizer comprises the above-mentioned atomizer assembly, and the electronic atomizer also comprises a battery assembly, wherein the battery assembly is matched with one end of the atomizer assembly and is electrically connected to the atomizer assembly.

[0019] In the above-mentioned atomization assembly, a gap is formed between the side of the heating element and the groove wall of the installation groove. Under the capillary action of the liquid, the gap can absorb the surrounding excess aerosol generating matrix and store it on the side of the heating element, thereby effectively preventing the leakage of the aerosol generating matrix. Moreover, since the gap inside the heating element is smaller, when the heating element needs to be supplied with liquid, the aerosol generating matrix in the above-mentioned gap can flow into the heating element, thereby changing the liquid supply direction of the heating element from a single top surface liquid inlet to top surface liquid inlet and side surface liquid inlet at the same time, thereby significantly increasing the liquid inlet area of ​​the heating element, effectively preventing the occurrence of insufficient liquid supply. Moreover, since the sealing part is protruding, the area of ​​the connecting groove can also be increased, thereby further increasing the liquid supply area. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] 1 and 2, an embodiment of the present application provides an electronic atomizer 100 for heating and atomizing atomized liquid to generate aerosol for use by a user. The above-mentioned aerosol generating substrate includes but is not limited to materials used for medical, health, wellness, and beauty purposes.

[0037] The electronic atomizer 100 provided in the embodiment of the present application includes an atomizer assembly 20 and a battery assembly 40. The battery assembly 40 is electrically connected to the atomizer assembly 20 to provide electrical energy to the atomizer assembly 20. The atomizer assembly 20 is used to store atomized liquid and heat the atomized liquid under the action of the electrical energy of the battery assembly 40 to generate an aerosol for the user to take.

[0038] In the present embodiment, the atomizer assembly 20 includes a liquid storage chamber 214 and an atomizer core 23. The atomizer core 23 is detachably connected to the battery assembly. The atomizer assembly 20 is an independent component. After the atomizer medium in the liquid storage chamber 214 is used up, a new atomizer assembly 20 can be replaced. In other embodiments, the atomizer assembly 20 and the battery assembly 40 can also be fixedly connected, and the atomizer assembly 20 and the battery assembly 40 are not detachable. Alternatively, the atomizer core 23 of the atomizer assembly 20 can also be fixed to the battery assembly 40, and the part of the atomizer assembly 20 with the liquid storage chamber 214 can be detached to replace the atomizer medium in the liquid storage chamber 214 after use, and the atomizer core 2 can be not disassembled together with the part with the liquid storage chamber 214 to reduce the user's use cost.

[0039] Please continue to refer to FIG. 2 . The atomizer assembly 20 includes a housing 21 and an atomizer core 23 . The housing 21 is a shell-like structure with one end open. The atomizer core 23 is accommodated in the open end of the housing 21 . The other end of the housing 21 is provided with an exhaust pipe 212 and a liquid storage chamber 214 surrounding the exhaust pipe 212 in a circumferential direction. One end of the exhaust pipe 212 is matched with the atomizer core 23 . The other end of the exhaust pipe 212 extends to the closed end of the housing 21 . An exhaust channel 212a is formed in the exhaust pipe 212 to connect the atomizer core 23 and the external atmosphere. The liquid storage chamber 214 is used to store the atomizer liquid. The atomizer liquid in the liquid storage chamber 214 can flow into the atomizer core 23 and be heated and atomized by the atomizer core 23 . The aerosol generated by the atomization can flow out of the housing 21 through the exhaust channel 212a for the user to take. The battery assembly 40 is matched with the side of the atomizer assembly 20 where the atomizer core 23 is provided. The battery assembly 40 is electrically connected to the atomizer core 23 to supply power to the atomizer core 23 .

[0040] In the following embodiments, the height direction of the shell 21 is defined as the first direction (i.e., the Z direction in FIG. 2 ), the length direction of the shell 21 is defined as the second direction (i.e., the X direction in FIG. 2 ), and the width direction of the shell 21 is defined as the third direction (i.e., the Y direction in FIG. 3 ). The first direction, the second direction, and the third direction intersect with each other. As a preferred embodiment, the first direction, the second direction, and the third direction are perpendicular to each other.

[0041] Please refer to Figures 2 to 5, the atomizer core 23 includes a heating cover 232, a heating element 234 and a conductive electrode 236. The heating cover 232 is a hollow shell-like structure, and a mounting groove 2325 is provided at one end of the heating cover 232 away from the exhaust channel 212a in the first direction, and a liquid inlet cavity 2321 and two lower liquid channels 2323 are provided at one end of the heating cover 232 close to the exhaust channel 212a in the first direction. The liquid inlet cavity 2321 is located at the center of the heating cover 232, and the two lower liquid channels 2323 are respectively located at opposite sides of the liquid inlet cavity 2321 in the second direction, and the liquid inlet cavity 2321 and the two lower liquid channels 2323 are respectively connected to the mounting groove 2325. The heating element 234 is confined in the mounting groove 2325 , and the conductive electrode 236 is supported on the side of the heating element 234 away from the liquid inlet cavity 2321 . The conductive electrode 236 is electrically connected to the heating element 234 and presses the heating element 234 , thereby firmly confining the heating element 234 in the mounting groove 2325 .

[0042] In this way, the two lower liquid channels 2323 are respectively connected to the liquid storage chamber 214, and the atomized liquid in the liquid storage chamber 214 can flow into the heating element 234 of the mounting groove 2325 through the lower liquid channel 2323 and the liquid inlet chamber 2321. The heating element 234 can heat the atomized liquid under the action of the electric energy of the conductive electrode 236 to generate aerosol, and the aerosol enters the exhaust channel 212a.

[0043] Furthermore, the heating element 234 is a cubic structure and can be formed of a high temperature resistant porous material such as porous glass, porous ceramic or honeycomb ceramic. The length direction of the heating element 234 is parallel to the second direction, the width direction of the heating element 234 is parallel to the third direction, and the thickness direction of the heating element 234 is parallel to the first direction. The surface of the heating element 234 facing the conductive electrode 236 is covered with a metal material or an alloy material, wherein the alloy material can be selected from iron-chromium alloy, iron-chromium-aluminum alloy, iron-chromium-nickel alloy, chromium-nickel alloy, titanium alloy, stainless steel alloy, etc. The above metal heating element 234 or alloy heating element 234 is formed on one side of the heating element 234 by die stamping, casting, mechanical weaving, chemical etching or screen printing to form a heating surface. The surface of the heating element 234 facing the liquid inlet cavity 2321 and the lower liquid channel 2323 forms a liquid inlet surface 2341, and the side surface of the heating element 234 forms a side surface 2343 surrounding the liquid inlet surface 2341 along the circumferential direction. Since the liquid inlet surface 2341 of the heating element 234 is arranged toward the lower liquid channel 2323 , the atomized liquid flowing out of the lower liquid channel 2323 enters the heating element 234 from the liquid inlet surface 2341 .

[0044] As described in the background technology, in order to prevent the movement of the heating element 234 during assembly, which may cause the atomized liquid to leak from the gap between the heating element 234 and the groove wall of the mounting groove 2325, or cause poor contact between the heating element 234 and the conductive electrode 236, the designed gap between the heating element 234 and the groove wall of the mounting groove 2325 is very small, so the atomized liquid mainly enters the heating element 234 through the liquid inlet surface 2341. When the liquid inlet surface 2341 does not contact the atomized liquid for a long time due to the presence of bubbles or other reasons, it is easy to cause insufficient liquid supply to the heating element 234. Moreover, during the normal use of the electronic atomizer 100, the atomized liquid in the liquid storage chamber 214 will flow into the liquid inlet chamber 2321 through the air flow channel. If this part of the atomized liquid is not used, it will leak through the exhaust channel 212a, thereby affecting the user's experience.

[0045] Based on the above problems, as shown in Figures 3 to 6, a liquid storage space is formed between the groove wall of the mounting groove 2325 and the side 2343 of the heating element 234. In this way, a gap is formed between the side 2343 of the heating element 234 and the groove wall of the mounting groove 2325. Under the capillary action of the liquid, the gap can absorb the surrounding excess atomized liquid to be stored in the side 2343 of the heating element 234, thereby effectively preventing the leakage of the atomized liquid. Moreover, since the gap inside the heating element 234 is smaller, when the heating element 234 needs to be supplied with liquid, the atomized liquid in the above gap can flow into the heating element 234, so that the liquid supply direction of the heating element 234 is changed from a single top surface liquid inlet to a top surface liquid inlet and a side surface liquid inlet at the same time, thereby significantly increasing the liquid inlet area of ​​the heating element 234, effectively preventing the occurrence of insufficient liquid supply.

[0046] Specifically in some embodiments, two liquid storage spaces are formed between the groove wall of the installation groove 2325 and the side surface 2343 of the heating element 234. The two liquid storage spaces are respectively located on opposite sides of the width direction of the heating element 234, and the length direction of each liquid storage space is parallel to the length direction of the heating element 234, so that the cross-sectional area of ​​the liquid storage space perpendicular to the third direction is larger, thereby further increasing the liquid inlet area of ​​the heating element 234.

[0047] It can be understood that the number, position and shape of the liquid storage space are not limited thereto, and can be set as needed to meet different liquid supply requirements, and the liquid storage spaces can be interconnected through the gap between the groove wall of the mounting groove 2325 and the side 2343 of the heating element 234. For example, in some embodiments, a plurality of liquid storage spaces are formed between the groove wall of the mounting groove 2325 and the side 2343 of the heating element 234, and the plurality of liquid storage spaces are arranged at intervals along the circumference of the mounting groove 2325.

[0048] Further, in some embodiments, since the liquid storage space can only absorb and store the surrounding excess atomized liquid by capillary force, the width h of the liquid storage space in the direction perpendicular to the side 2343 of the heating element 234 cannot be too large. Specifically, the width h of each liquid storage space (as shown in FIG. 4 ) is less than 0.5 mm. As a preferred embodiment, the width h of each liquid storage space is 0.2 mm-0.3 mm, so as to achieve the best liquid absorption and storage effect.

[0049] It is understood that the specific formation method of the liquid storage space is not limited. In some embodiments, the groove wall of the installation groove 2325 is provided with at least one auxiliary liquid supply groove 2325b, and the liquid storage space is formed between the groove wall of the auxiliary liquid supply groove 2325b and the side surface 2343 of the heating element 234. In other embodiments, the groove wall of the installation groove 2325 is concave inward as a whole to form the liquid storage space.

[0050] In some embodiments, the atomizer assembly 20 further includes a seal 238 formed of a material having a certain elasticity, such as silicone. The seal 238 is limited in the mounting groove 2325 and is at least partially disposed on the side of the heating element 234 facing the liquid inlet cavity 2321 and the lower liquid channel 2323. The seal 238 penetrates along the first direction and is provided with a connecting groove 2381 connecting the lower liquid channel 2323 (and the liquid inlet cavity 2321) and the liquid inlet surface 2341. The seal 238 mainly plays a sealing role to prevent the leakage of the atomized liquid in the liquid storage cavity 214. At the same time, the setting of the connecting groove 2381 allows the atomized liquid in the liquid storage cavity 214 to flow smoothly into the heating element 234.

[0051] It can be seen that the size of the cross-sectional area of ​​the connecting groove 2381 perpendicular to the first direction determines the amount of liquid supplied to the heating element 234 per unit time, and in order to increase the amount of liquid supplied per unit time, it is necessary to increase the cross-sectional area of ​​the connecting groove 2381 perpendicular to the first direction. However, if the cross-sectional area of ​​the connecting groove 2381 perpendicular to the first direction is too large, the thickness of the groove wall of the connecting groove 2381 will be too narrow, so that the sealing member 238 is prone to tilt when under pressure, causing the original surface seal to become a line seal, thereby causing the seal to fail.

[0052] Please refer to Figures 4 to 8. In the present application, since a liquid storage space is formed between the groove wall of the installation groove 2325 and the side 2343 of the heating element 234, the sealing member 238 partially protrudes from the side 2343 of the heating element 234 and extends into the liquid storage space. In this way, as the outer dimension of the sealing member 238 perpendicular to the first direction increases, the area of ​​the connecting groove 2381 can also increase accordingly, thereby further increasing the liquid supply area.

[0053] Specifically, a plurality of protrusions 2383 are protruded from the side wall of the sealing member 238 , and all the protrusions 2383 extend into the liquid storage space, thereby further increasing the outer dimension of the sealing member 238 perpendicular to the first direction.

[0054] Specifically, in some embodiments, two auxiliary liquid supply grooves 2325b are provided on the groove wall of the installation groove 2325, and the two auxiliary liquid supply grooves 2325b are respectively located on opposite sides of the width direction of the heating element 234. Correspondingly, a protrusion 2383 is respectively provided on the outer surface of the sealing member 238 on opposite sides in the second direction, and each protrusion 2383 protrudes from the opposite sides of the width direction of the heating element 234, and each protrusion 2383 extends into an auxiliary liquid supply groove 2325b, and the shape of the protrusion 2383 matches the shape of the auxiliary liquid supply groove 2325b. In another embodiment, the groove wall of the installation groove 2325 is provided with only one auxiliary liquid supply groove 232, and the auxiliary liquid supply groove 232 is located on one side in the width direction of the heating element 234, and a protrusion 2383 is respectively provided on the outer surface of the sealing member 238 on one side in the second direction, and the protrusion 2383 extends into the auxiliary liquid supply groove 2325b.

[0055] As a preferred embodiment, the ratio of the width b of the portion of the groove wall of the connecting groove 2381 provided with the protrusion 2383 in the second direction to the height a of the groove wall of the connecting groove 2381 in the first direction is greater than 1, so that the seal 238 is not easily deformed during the assembly process. It can be understood that the specific value of the ratio of the width of the portion of the groove wall of the connecting groove 2381 provided with the protrusion 2383 in the second direction to the height of the groove wall of the connecting groove 2381 in the first direction is not limited, and can be set as needed to meet different sealing requirements.

[0056] It can be understood that the shape, number and arrangement of the protrusions 2383 are not limited thereto. For example, in another embodiment, the seal 238 is provided with a protrusion 2383 on two opposite sides in the length direction and on two opposite sides in the width direction, respectively, and the four protrusions 2383 extend into the four liquid storage spaces respectively.

[0057] The above-mentioned atomization assembly 20 and electronic atomizer 100 effectively increase the liquid supply area of ​​the heating element 234 by forming a liquid storage space and protruding the heating element 234, thereby preventing the aerosol from producing a burnt smell due to insufficient liquid supply. At the same time, the excess atomization liquid around the mounting groove 2325 is reasonably utilized, which can effectively prevent the electronic atomizer 100 from leaking liquid and affecting the user experience of the electronic atomizer 100.

[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
