Description

Technical Field

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

[0002] Atomizers are used to heat and atomize a liquid aerosol matrix to produce an inhalable aerosol. Atomizers typically include an atomizer and a power supply. The atomizer primarily stores the liquid matrix and, when powered, atomizes it through a heating element.

[0003] At present, an atomizer usually includes a liquid storage chamber, a heating element, an air outlet pipe, a nozzle and a sealing plug. The atomized gas generated by heating and atomizing by the heating element is transmitted to the nozzle through the air outlet pipe. The sealing plug is arranged at the end of the air outlet pipe to avoid liquid and air leakage; the sealing plug is generally connected to the air outlet pipe by plugging. However, since the wall of the air outlet pipe is thin, the end of the air outlet pipe is sharp; when the air outlet pipe and the sealing plug are plugged in, the contact support area between the two is too small, which can easily cause the air outlet pipe to scrape the sealing plug or destroy the sealing plug structure. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide an atomizer and an atomizing device, aiming to solve the problem that when the outlet pipe of the existing atomizer is connected to the sealing plug, the outlet pipe may easily scratch the sealing plug or destroy the sealing plug structure due to the small contact support area between the two.

[0005] To achieve the above objectives, the technical solution adopted in this application is:

[0006] In a first aspect, an embodiment of the present application provides an atomizer, comprising a shell assembly, a support member, and a sealing member; an air outlet pipe is provided in the shell assembly; the sealing member is provided in the shell assembly, the sealing member has an insertion hole, and the sealing member forms an abutment surface in the insertion hole, the support member is provided at the top end of the air outlet pipe, and the top end of the support member has a supporting surface for abutting against the abutment surface.

[0007] The beneficial effect of the present application is that: a support member is provided on the air outlet pipe of the atomizer, and the top end of the support member has a supporting surface. The support member has a good contact area with the sealing member through the supporting surface. When the support member and the sealing member are squeezed and contacted with each other, the force is evenly dispersed, and then the support member can provide better support, thereby preventing the seal and the air outlet pipe from being directly squeezed and contacted during the assembly process, causing the air outlet pipe to scrape the seal or destroy the seal structure.

[0008] In some embodiments, the support member includes a main body for being sleeved with the air outlet pipe and a convex ring provided on the outer side surface of the main body near the top, and the convex ring protrudes outward from the main body in the circumferential direction; the main body is sleeved inside the air outlet pipe, and the convex ring is facing away from the support surface end and abuts against the top of the air outlet pipe.

[0009] By adopting the above technical solution, the main body is sleeved inside the air outlet pipe, and only the convex ring is exposed outside, which does not affect the plug-in relationship between the air outlet pipe and the seal; the convex ring can isolate the top of the seal from the seal.

[0010] In some embodiments, the outer edge of the top end of the protruding ring is provided with a rounded corner.

[0011] By adopting the above technical solution, a rounded corner is provided at the top of the convex ring, so that the edge of the convex ring is rounded, thereby improving contact safety.

[0012] In some embodiments, the outer diameter of the protruding ring is equal to the outer diameter of the air outlet pipe.

[0013] By adopting the above technical solution, the outer wall of the convex ring and the outer wall of the outlet pipe are on the same plane, and the structural integrity is good; the support member will not increase the structural size of the outlet pipe in the radial direction, and the structural integrity is good.

[0014] In some embodiments, the support member has a through hole extending therethrough, and the aperture of the through hole gradually increases from the top end to the bottom end of the support member.

[0015] By adopting the above technical solution, the aperture of the through hole closer to the top of the support member is smaller, which is beneficial to increasing the area of ​​the supporting surface of the support member, so that the contact between the support member and the sealing member has better support; the aperture of the through hole closer to the bottom of the support member is larger, which is beneficial to the rapid entry of the atomized gas in the outlet pipe into the through hole, thereby increasing the output of the atomized gas.

[0016] In some embodiments, the seal also has an air hole, one end of the air hole extends to the abutment surface to connect the air hole with the through hole; the other end of the air hole extends to the top of the seal; the aperture of the air hole is smaller than the aperture of the plug hole.

[0017] By adopting the above technical solution, the through hole is connected to the outside of the sealing member through the air hole; and the plug hole does not penetrate the sealing member so that an abutting surface is formed inside the sealing member.

[0018] In some embodiments, the air holes are arranged to overlap with the through holes.

[0019] By adopting the above technical solution, the atomized gas in the through hole can enter the air hole more smoothly.

[0020] In some embodiments, the sealing member is provided with an annular protrusion on the inner wall surface of the plug hole for interference fit with the air outlet pipe.

[0021] By adopting the above technical solution, effective sealing is achieved through the interference fit between the annular protrusion and the air outlet pipe.

[0022] In some embodiments, the shell assembly includes an atomizing shell and a nozzle arranged at the top of the atomizing shell; the air outlet pipe is arranged in the atomizing shell, and the top of the atomizing shell has a liquid injection port surrounding the air outlet pipe, and the sealing member is used to seal the liquid injection port.

[0023] By adopting the above technical solution, the sealing member is sealed at the liquid filling port and plugged into the air outlet pipe, and then the sealing member can form an effective seal between the atomizer shell and the suction nozzle, preventing liquid and air leakage, and improving product reliability.

[0024] In a second aspect, an embodiment of the present application further provides an atomization device, comprising a power supply assembly and the atomizer, wherein the power supply assembly is used to supply power to the atomizer. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The atomizing device is used to heat and atomize a liquid aerosol matrix that can be atomized to generate an aerosol that can be inhaled. The atomizing device generally includes an atomizer and a power supply assembly, wherein the atomizer is mainly used to store the liquid matrix and atomize the liquid matrix through the heating element after power is turned on. The atomizer usually has a liquid storage chamber, a heating element, an air outlet pipe, a mouthpiece and a sealing plug. The atomized gas generated by heating and atomizing by the heating element is transferred to the mouthpiece through the air outlet pipe. The sealing plug is set at the end of the air outlet pipe to avoid liquid and air leakage; the sealing plug is generally connected to the air outlet pipe by plugging, but because the wall of the air outlet pipe is thin, the end of the air outlet pipe is sharp; when the air outlet pipe and the sealing plug are plugged in, the contact support area between the two is too small, which can easily cause the air outlet pipe to scrape the sealing plug or damage the sealing plug structure.

[0046] Based on this, in order to solve the above problems, the present application designs a seal, in which a support member is arranged on the air outlet pipe of the atomizer, and the top end of the support member has a supporting surface. When the support member and the seal are squeezed and contacted with each other, the support member has a good contact area with the seal through the supporting surface, so that the force is evenly dispersed, and then the support member can provide better support, preventing the seal and the air outlet pipe from being directly squeezed and contacted during the assembly process, causing the air outlet pipe to scrape the seal or destroy the seal structure.

[0047] Please refer to Figure 1 、 Figure 2 、 Figure 3The embodiment of the present application provides an atomizer 100, which includes a shell assembly 1, a support member 3 and a sealing member 2; an air outlet pipe 4 is provided in the shell assembly 1; the sealing member 2 is provided in the shell assembly 1, and the sealing member 2 has a plug hole 201 for plugging the air outlet pipe 4, and the sealing member 2 has a contact surface 21 formed in the plug hole 201; the support member 3 is provided at the top end of the air outlet pipe 4, and the top end of the support member 3 has a supporting surface 31 for abutting against the abutment surface 21.

[0048] Specifically, the support member 3 is disposed at the top of the outlet pipe 4. During the insertion of the outlet pipe 4 into the seal 2, the support member 3 prevents the top of the outlet pipe 4 from directly pressing and contacting the seal 2. Due to the thin wall of the outlet pipe 4, direct pressing and contact between the top of the outlet pipe 4 and the seal 2 could easily damage the seal 2, or the outlet pipe 4 could be inserted into the seal 2, damaging the structure of the seal 2. The top of the support member 3 has a supporting surface 31. The support member 3 is inserted into the insertion hole 201 and presses and contacts the abutment surface 21. The support member 3 has a good contact area with the seal 2 through the supporting surface 31, so that the force is evenly distributed, thereby improving the structural stability of the support member 3.

[0049] It is understandable that the support member 3 can be sleeved on the inside of the outlet pipe 4, or on the outside of the outlet pipe 4; this is not limited here, as long as the support member 3 can be stably connected to the outlet pipe 4.

[0050] The atomizer 100 of the present application is provided with a support member 3 on the air outlet pipe 4 of the atomizer 100. The support member 3 has a good contact area with the seal 2 through the support surface 31, which can provide good support, thereby preventing the seal 2 and the air outlet pipe 4 from directly squeezing and contacting each other during the assembly process, causing the air outlet pipe 4 to scrape the seal 2 or destroy the structure of the seal 2, thereby improving the contact safety between components.

[0051] Understandably, reference Figure 1 The housing assembly 1 includes a mouthpiece 5, within which is formed a mouthpiece airway 501. The outlet pipe 4 communicates with the mouthpiece airway 501, allowing the aerosol generated by the atomizer 100 to be delivered to the mouthpiece airway 501 through the outlet pipe 4 for smooth inhalation by the user. A seal 2 is disposed between the outlet pipe 4 and the mouthpiece 5. The outlet pipe 4 is inserted into the insertion hole 201 of the seal 2, which communicates with the mouthpiece airway 501. This seal 2 effectively seals the outlet pipe 4 and the mouthpiece airway 501, reducing gas leakage and increasing atomization yield.

[0052] refer to Figure 3-Figure 5In some embodiments, the support member 3 includes a main body 301 for being sleeved with the air outlet pipe 4 and a convex ring 302 provided on the outer side surface of the main body 301 near the top. The convex ring 302 protrudes outward from the main body 301 in the circumferential direction. The main body 301 is sleeved inside the air outlet pipe 4, and the convex ring 302 is in contact with the top of the air outlet pipe 4 at the end facing away from the support surface 31.

[0053] Specifically, the support member 3 is a cylindrical structure, and the main body 301 is sleeved and matched with the air outlet pipe 4; Figure 3 、 Figure 4 The main body 301 is sleeved on the inside of the outlet pipe 4, that is, only the convex ring 302 is exposed to the outside of the outlet pipe 4. The structure is simple and beautiful, and the main body 301 does not increase the size of the outlet pipe 4 in the radial direction, and does not affect the connection between the outlet pipe 4 and the seal 2.

[0054] The main body 301 and the air outlet pipe 4 can be connected and limited by means of, but not limited to, snap connection, interference fit, etc., so that the main body 301 and the air outlet pipe 4 are structurally connected firmly.

[0055] The end of the convex ring 302 facing away from the supporting surface 31 is in contact with the top of the air outlet pipe 4, and the top surface of the main body 301 and the top surface of the convex ring 302 together form the supporting surface 31; then the convex ring 302 can effectively separate the top of the air outlet pipe 4 from the sealing member 2 to prevent the top of the air outlet pipe 4 from being squeezed and contacted with the sealing member 2; through the squeezing contact between the supporting surface 31 of the support member 3 and the sealing member 2, the force can be better dispersed and the structural stability can be improved.

[0056] refer to Figure 4 、 Figure 5 In some embodiments, the outer edge of the top end of the protruding ring 302 is provided with a rounded corner 6.

[0057] It can be understood that when the air outlet pipe 4 is plugged into the sealing member 2, the support member 3 will be in direct contact with the sealing member 2 along the insertion direction of the air outlet pipe 4. By setting a rounded corner 6 on the outer edge of the top of the convex ring 302, the outer edge of the top of the convex ring 302 is rounded, thereby improving contact safety.

[0058] refer to Figure 2 、 Figure 4 The outer diameter of the convex ring 302 is equal to the outer diameter of the outlet pipe 4.

[0059] Specifically, refer to Figure 4 The outer wall of the convex ring 302 is on the same plane as the outer wall of the outlet pipe 4, so the support member 3 does not increase the size of the outlet pipe 4 in the radial direction. The support member 3 is tightly combined with the outlet pipe 4, and the structural integrity is good.

[0060] The size of the plug hole 201 of the sealing member 2 is set according to the outer diameter of the air outlet pipe 4. After the air outlet pipe 4 is plugged into the plug hole 201, the outer wall of the air outlet pipe 4 and the outer wall of the convex ring 302 can fit tightly with the inner wall of the plug hole 201.

[0061] refer to Figure 5 In some embodiments, the support member 3 has a through hole 7 extending therethrough, and the aperture of the through hole 7 gradually increases from the top to the bottom of the support member 3 .

[0062] Specifically, the aperture size of the through hole 7 is designed to be conically distributed in the axial direction. The closer the through hole 7 is to the top of the support member 3, the smaller the aperture is, which is beneficial to increase the area of ​​the supporting surface 31 at the top of the support member 3, so that the contact between the support member 3 and the seal 2 has better support; and the closer the through hole 7 is to the bottom of the support member, the larger the aperture is, which is beneficial for the atomized gas in the outlet pipe 4 to quickly enter the through hole 7, increase the gas output of the atomized gas, and make the gas flow quickly.

[0063] refer to Figure 1 、 Figure 4 In some embodiments, the seal 2 further has an air hole 202, one end of the air hole 202 extends to the abutting surface 21 to connect the air hole 202 with the through hole 7; the other end of the air hole 202 extends to the top of the seal 2; the aperture of the air hole 202 is smaller than the aperture of the plug hole 201.

[0064] As can be understood, the air hole 202 and the insertion hole 201 extend in the same direction, establishing communication between the insertion hole 201 and the exterior of the sealing member 2 through the air hole 202. Furthermore, the diameter of the air hole 202 is smaller than that of the insertion hole 201, allowing the sealing member 2 to form an abutment surface 21 within the insertion hole 201. The air outlet pipe 4 is inserted into the insertion hole 201, and the support surface 31 of the support member 3 can be positioned and abutted against the abutment surface 21 along the insertion direction, thus providing a positioning function for insertion. The air hole 202 is connected to the insertion hole 201, allowing the atomized gas in the air outlet pipe 4 to smoothly pass through the through hole 7 in the support member 3 and the air hole 202 to the nozzle air passage 501.

[0065] refer to Figure 4 In some embodiments, the air hole 202 is arranged to coincide with the through hole 7 .

[0066] Specifically, the air hole 202 is arranged to overlap with the through hole 7 , that is, the central axis of the air hole 202 overlaps with the central axis of the through hole 7 , which is more conducive to the flow of gas between the through hole 7 and the air hole 202 .

[0067] In some embodiments, the aperture size of the top of the through hole 7 is equal to the aperture size of the bottom of the air hole 202, so that the atomized gas in the through hole 7 can enter the air hole 202 more smoothly, reducing the impact on the atomized gas flow rate.

[0068] refer to Figure 1 、 Figure 4 In some embodiments, the sealing member 2 is provided with an annular protrusion 8 on the inner wall surface of the plug hole 201 for interference fit with the air outlet pipe 4.

[0069] It can be understood that the air outlet pipe 4 is inserted into the insertion hole 201, and the annular protrusion 8 is interference-fitted with the air outlet pipe 4 to achieve effective sealing, thereby reducing air leakage during the atomized gas transmission process.

[0070] refer to Figure 1-Figure 3 In some embodiments, the housing assembly 1 includes an atomizing shell 101 and a nozzle 5 disposed at the top of the atomizing shell 101; the air outlet pipe 4 is disposed in the atomizing shell 101, and the top of the atomizing shell 101 has a liquid injection port 9 surrounding the air outlet pipe 4, and the sealing member 2 is used to seal the liquid injection port 9.

[0071] Specifically, the aerosol matrix can be replenished in the atomizer shell 101 through the liquid injection port 9. The seal 2 is sealed at the liquid injection port 9 and plugged into the air outlet pipe 4. Then, the seal 2 can form an effective seal between the atomizer shell 101 and the suction nozzle 5 to prevent liquid and air leakage, thereby improving product reliability.

[0072] refer to Figure 1 The present application also provides an atomization device 200 , comprising a power supply assembly 10 and the above-mentioned atomizer 100 , wherein the power supply assembly 10 is used to supply power to the atomizer 100 .

[0073] It can be understood that the atomizer 100 is specifically used in the atomizing device 200. The atomizer 100 includes a heating component 11, which is used to heat and atomize the aerosol matrix to generate aerosol atomized gas for the user to inhale. The atomized gas flows through the air outlet pipe 4 to the mouthpiece 5 to reach the user's mouth.

[0074] The power supply assembly 10 includes a battery 1001 electrically connected to the heating assembly 11 , and the battery 1001 is used to supply power to the heating assembly 11 .

[0075] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
