Description

Technical Field

[0001] The invention particularly relates to an ultrasonic atomization core and an ultrasonic atomizer. Background Art

[0002] The existing ultrasonic atomizer core includes an atomizer sleeve, in which an ultrasonic atomizer sheet and oil-conducting cotton connected to the outside and the atomizing surface of the ultrasonic atomizer sheet are arranged. When working, the oil-conducting cotton guides the external liquid smoke-producing material to the ultrasonic atomizer sheet for atomization to generate smoke.

[0003] Existing ultrasonic atomizer sheets are generally planar in shape, and the temperature at the center is relatively high, which can easily burn holes in the oil-conducting cotton in contact with it and cause dry burning, affecting the atomization effect. The service life of the oil-conducting cotton and the ultrasonic atomizer sheet is short. At the same time, the planar ultrasonic atomizer sheet does not have the effect of accumulating energy, requires a large working power, and has a low power endurance. In addition, when the atomizer core is installed in the atomizer housing, the cylindrical elastic electrode of the atomizer directly abuts against the center of the ultrasonic atomizer sheet, and a slight force during assembly will cause the ultrasonic atomizer sheet to crack. Summary of the invention

[0004] The existing ultrasonic atomizer sheet is generally planar, and the temperature at the center is relatively high, so it is easy to burn holes in the oil-conducting cotton in contact with it and dry burn it, affecting the atomization effect, and the service life of the oil-conducting cotton and the ultrasonic atomizer sheet is short. At the same time, the planar ultrasonic atomizer sheet does not have the effect of accumulating energy, requires a large working power, and has a low power supply endurance. In addition, when the atomizer core is installed in the atomizer housing, the cylindrical elastic electrode of the atomizer directly abuts against the center of the ultrasonic atomizer sheet, and a little force during assembly will cause the ultrasonic atomizer sheet to top crack. The purpose of the present invention is to provide an ultrasonic atomizer core and an ultrasonic atomizer in view of the deficiencies of the above-mentioned prior art, wherein the ultrasonic atomizer sheet has a fast liquid guiding speed, is not easy to burn through or dry burn the oil-conducting cotton, has a good atomization effect, and has a long service life of the oil-conducting cotton and the ultrasonic atomizer sheet; the ultrasonic atomizer sheet can effectively accumulate energy to atomize and produce smoke, requires a relatively low working power, and has a strong power supply endurance; the ultrasonic atomizer sheet is evenly stressed during assembly and is not easy to break.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] An ultrasonic atomization core comprises an atomization sleeve, wherein an ultrasonic atomization sheet and oil-conducting cotton connected to the outside and the atomization surface of the ultrasonic atomization sheet are arranged in the atomization sleeve, and the structural characteristics are that the ultrasonic atomization sheet is spherical, the oil-conducting cotton has a spherical portion, the curvature of the spherical portion of the oil-conducting cotton is greater than or equal to the curvature of the spherical ultrasonic atomization sheet, and the convex surface of the spherical portion of the oil-conducting cotton is in contact with the concave surface of the ultrasonic atomization sheet.

[0007] By means of the above structure, since the ultrasonic atomizer is spherical, the oil-conducting cotton has a spherical portion in contact with the concave surface of the ultrasonic atomizer, so the oil-conducting cotton makes the liquid conduction speed faster on the contact surface of the spherical portion through its own spherical curvature, and the liquid smoke-producing material flows to the center of the ultrasonic atomizer faster, so that the center of the ultrasonic atomizer with a higher temperature can replenish the liquid in time, and the temperature of the center of the ultrasonic atomizer can be reduced to prevent the center of the ultrasonic atomizer from being too high and burning through the oil-conducting cotton there. The ultrasonic atomizer will not dry burn and stop working, and the atomization effect is good. The oil-conducting cotton and the ultrasonic atomizer have a long service life. At the same time, the contact area between the oil-conducting cotton and the ultrasonic atomizer in spherical contact is larger, and the amount of smoke generated by atomization is more, and the amount of smoke is guaranteed, which meets the user's demand for smoke and improves the user experience. In addition, since the spherical ultrasonic atomizer has the function of focusing energy, the required working power is lower and the power supply has a strong endurance.

[0008] Since the ultrasonic atomizer is spherical, the oil-conducting cotton has a spherical portion in contact with the concave surface of the ultrasonic atomizer. Therefore, when the ultrasonic atomizer is working, the ultrasonic atomizer generates high-frequency oscillations to scatter the liquid smoke-producing substance on the concave surface of the ultrasonic atomizer and splash onto the edge of the concave surface. Therefore, a lot of droplets will accumulate on the concave surface, so the droplets can easily flow back to the concave surface and participate in atomization again, saving liquid smoke-producing substance and reducing the cost of use.

[0009] The curvature of the spherical portion of the oil-conducting cotton can be greater than or equal to the curvature of the spherical ultrasonic atomizer. When the curvature of the spherical portion of the oil-conducting cotton is equal to the curvature of the spherical ultrasonic atomizer, the liquid smoke-producing substance conducts liquid faster on the spherical contact surface. When the curvature of the spherical portion of the oil-conducting cotton is greater than the curvature of the spherical ultrasonic atomizer, a portion of the liquid smoke-producing substance is retained in the gap between the spherical portion of the oil-conducting cotton and the atomizing surface of the ultrasonic atomizer. Once the liquid smoke-producing substance is replenished, the liquid smoke-producing substance can flow faster to the center of the ultrasonic atomizer through the above-mentioned gap, and the liquid conduction and atomization effects are better.

[0010] As a preferred embodiment, the central axis of the surface of the oil-conducting cotton ball is colinear with the central axis of the ultrasonic atomization sheet.

[0011] Furthermore, it also includes an inner sleeve sleeved in the atomizing sleeve, the oil-conducting cotton also includes a cylindrical portion, the cylindrical portion is connected to the spherical portion to form a cup-shaped structure, the cylindrical portion is clamped between the atomizing sleeve and the inner sleeve, and the atomizing sleeve is provided with a through hole connecting the cylindrical portion with the outside.

[0012] Furthermore, it also includes a cotton pressing structure, one end of which is in contact with the inner sleeve, and the other end of which is in contact with the concave surface of the oil-conducting cotton ball surface.

[0013] The cotton pressing structure can ensure reliable contact between the oil-conducting cotton and the atomizing surface.

[0014] As a preferred embodiment, the cotton pressing structure includes an annular portion and at least three first elastic strands, the fixed ends of the first elastic strands are connected to the annular portion, the free ends of the first elastic strands abut against the oil-conducting cotton ball surface, and the annular portion abuts against the inner sleeve.

[0015] As a preferred embodiment, the first elastic strands are evenly arranged along the circumference of the annular portion, and the free ends of the first elastic strands are arc-shaped and fit with the concave surface of the oil-conducting cotton ball, so that the oil-conducting cotton is evenly stressed.

[0016] Based on the same inventive concept, the present invention also provides an ultrasonic atomizer, comprising a shell, wherein the ultrasonic atomization core is arranged inside the shell.

[0017] Furthermore, the shell is provided with an elastic electrode abutting against the convex surface of the ultrasonic atomization sheet.

[0018] As a preferred embodiment, the elastic electrode includes a cylindrical portion and at least three second elastic strands, the fixed ends of the second elastic strands are connected to the cylindrical portion, and the free ends of the second elastic strands are in contact with the convex surface of the ultrasonic atomization sheet.

[0019] The elastic electrode of the above structure can ensure that the ultrasonic atomizer sheet is subjected to uniform force on all sides, prevent the ultrasonic atomizer sheet from being broken due to force in a single direction, and is easy to assemble.

[0020] As a preferred embodiment, the second elastic strands are evenly arranged on the end surface of the cylindrical portion, and the free ends of the second elastic strands are arc-shaped and fit with the convex surface of the ultrasonic atomization sheet.

[0021] Compared with the prior art, the ultrasonic atomizer sheet in the present invention has a fast liquid conduction speed, is not easy to burn through or dry-burn the oil-conducting cotton, has a good atomization effect, and has a long service life of the oil-conducting cotton and the ultrasonic atomizer sheet; the ultrasonic atomizer sheet can effectively accumulate energy to atomize and produce smoke, requires lower working power, and has a strong power supply endurance; the ultrasonic atomizer sheet is evenly stressed during assembly and is not easy to break.

DETAILED DESCRIPTION

[0032] like Figures 1 to 4 As shown, the ultrasonic atomization core includes an atomization sleeve 1, in which an ultrasonic atomization sheet 2 and an oil-conducting cotton 3 connected to the outside and the atomization surface of the ultrasonic atomization sheet 2 are arranged. The ultrasonic atomization sheet 2 is spherical, and the oil-conducting cotton 3 has a spherical portion 301. The curvature of the spherical portion 301 of the oil-conducting cotton 3 is greater than or equal to the curvature of the spherical ultrasonic atomization sheet 2. The convex surface of the spherical portion 301 of the oil-conducting cotton 3 contacts the concave surface of the ultrasonic atomization sheet 2. The central axis of the spherical portion 301 of the oil-conducting cotton 3 is collinear with the central axis of the ultrasonic atomization sheet 2.

[0033] Since the ultrasonic atomizer sheet 2 is spherical, when the ultrasonic atomizer sheet 2 is working, the ultrasonically atomized liquid smoke-producing material splashes everywhere. When splashed droplets accumulate on the spherical surface of the ultrasonic atomizer sheet 2, the droplets can slide along the spherical surface to the center of the ultrasonic atomizer sheet 2 and be recovered and atomized again; the oil-conducting cotton 3 has a spherical portion 301 in contact with the concave surface of the ultrasonic atomizer sheet 2. When the ultrasonic atomizer sheet 2 is working, the splashed droplets are directly absorbed by the spherical portion 301, thereby making the liquid smoke-producing material of the oil-conducting cotton 3 on the contact surface of the spherical surface More smoke material and liquid smoke-producing material are affected by the gravity generated by the curvature of the spherical surface, making the liquid conduction speed faster. The liquid smoke-producing material flows to the center of the ultrasonic atomizer 2 faster, so that the center of the ultrasonic atomizer 2 with a higher temperature can be replenished with liquid in time, which can reduce the temperature of the center of the ultrasonic atomizer 2 and prevent the center of the ultrasonic atomizer 2 from being too high and burning through the oil-conducting cotton 3. The ultrasonic atomizer 2 will not burn dry, and the working continuity and atomization effect are good. The oil-conducting cotton 3 and the ultrasonic atomizer 2 have a long service life. At the same time, the contact area between the oil-conducting cotton 3 and the ultrasonic atomizer 2 that are in contact with the spherical surface is larger, and the amount of smoke generated by atomization is more. The direction of smoke atomization is as follows: Figure 2 In addition, since the spherical ultrasonic atomization sheet 2 has the function of focusing energy, the required working power is relatively low and the power supply endurance is strong.

[0034] The curvature of the spherical portion 301 of the oil-conducting cotton 3 may be greater than or equal to the curvature of the spherical ultrasonic atomizing sheet 2. When the curvature of the spherical portion 301 of the oil-conducting cotton 3 is equal to the curvature of the spherical ultrasonic atomizing sheet 2, the liquid smoke-generating substance conducts liquid faster on the spherical contact surface. Figure 3 As shown, when the curvature of the spherical portion 301 of the oil-conducting cotton 3 is greater than the curvature of the spherical ultrasonic atomization sheet 2, a portion of the liquid smoke-producing material is retained in the gap between the spherical portion 301 of the oil-conducting cotton 3 and the atomizing surface of the ultrasonic atomization sheet 2, so that the liquid smoke-producing material can flow to the center of the ultrasonic atomization sheet 2 faster, and the liquid guiding and atomization effects are better.

[0035] The ultrasonic atomizing core also includes an inner sleeve 4 which is sleeved in the atomizing sleeve 1. The oil-guiding cotton 3 also includes a cylindrical portion 302. The cylindrical portion 302 is connected to the spherical portion 301 to form a cup-shaped structure. The cylindrical portion 302 is sandwiched between the atomizing sleeve 1 and the inner sleeve 4. The atomizing sleeve 1 is provided with a through hole 101 which connects the cylindrical portion 302 with the outside.

[0036] The ultrasonic atomizing core further comprises a cotton pressing structure 5, one end of which abuts against the inner sleeve 4, and the other end of which abuts against the concave surface of the spherical portion 301 of the oil-conducting cotton 3. The cotton pressing structure 5 can ensure that the oil-conducting cotton 3 is in reliable contact with the atomizing surface.

[0037] The cotton pressing structure 5 includes a circular ring portion 501 and four first elastic strands 502. The fixed ends of the first elastic strands 502 are connected to the circular ring portion 501, and the free ends of the first elastic strands 502 abut against the spherical portion 301 of the oil-conducting cotton 3. Each first elastic strand 502 is evenly arranged around the circular ring portion 501. The free ends of the first elastic strands 502 are arc-shaped and fit against the concave surface of the spherical portion 301 of the oil-conducting cotton 3. The circular ring portion 501 abuts against the inner sleeve 4, so that the oil-conducting cotton 3 is evenly stressed.

[0038] like Figures 5 to 9 As shown, the ultrasonic atomizer comprises a shell 6, and the ultrasonic atomization core is arranged inside the shell 6.

[0039] The housing 6 is provided with an elastic electrode 7 which abuts against the convex surface of the ultrasonic atomizing sheet 2 .

[0040] The elastic electrode 7 includes a cylindrical portion 701 and four second elastic strands 702, the fixed end of the second elastic strand 702 is connected to the cylindrical portion 701, and the free end of the second elastic strand 702 is in contact with the convex surface of the ultrasonic atomization sheet 2. Each second elastic strand 702 is evenly arranged on the end face of the cylindrical portion 701, and the free end of the second elastic strand 702 is arc-shaped and fits the convex surface of the ultrasonic atomization sheet 2. The elastic electrode 7 of the above structure can ensure that the ultrasonic atomization sheet 2 is subjected to uniform force all around, prevent the ultrasonic atomization sheet 2 from breaking due to force in a single direction, and is easy to assemble.

[0041] The housing 6 includes a top cover 601 , a base 602 and a bottom cover 603 which are connected in sequence.

[0042] The atomizing core is connected to the top cover 601 through the connecting sleeve 8 and is arranged inside the top cover 601 .

[0043] A rotatable suction nozzle 9 is disposed on the top of the top cover 601. The suction nozzle 9 is provided with an air inlet 901 and an oil injection hole 902.

[0044] An oil tank 10 is provided in the top cover 601. The through hole 101 communicates the cylindrical portion 302302 with the oil tank 10. By rotating the suction nozzle 9, the oil filling hole 902 and the oil through hole 1001 of the oil tank 10 can be aligned or misaligned, thereby opening or closing the oil tank 10 for oil filling operation.

[0045] A sealing gasket 11 is provided between the oil bin 10 and the suction nozzle 9 .

[0046] The ultrasonic atomizer sheet 2 is fixed in the bottom cover 603 via a silicone base 12 .
