- the side wall of the air outlet is relatively long; and when smoke passes through the air outlet, the smoke hits the side wall of the air outlet, and the ceramic on the side wall of the air outlet absorbs large-particle e-liquid droplets, thereby preventing the user from inhaling e-liquid droplets and improving the taste of smoke.

- E-liquid can be stored in these e-liquid storing gaps (that is, the e-liquid is in direct contact with the surface of the ultrasonic atomizing sheet), and the bottom surface of the e-liquid storing cotton placed in the placement groove is flush with the rough surface, so that the e-liquid on the rough surface can be absorbed by the e-liquid storing cotton, and the e-liquid on the e-liquid storing cotton can be stored by the rough surface.
- the oscillation frequencies and intensities at different positions of the same ultrasonic atomizing sheet are different, that is, the efficiencies of atomizing e-liquid into smoke at different positions of the same ultrasonic atomizing sheet are different.
- the e-liquid storing cotton has relatively strong capacity of storing e-liquid, that is, the e-liquid storing cottonstores much e-liquid, while the e-liquid guide ceramic stores a little e-liquid, so the e-liquid storing cotton and the rough surface respectively abut against different positions of the ultrasonic atomizing sheet to avoid the phenomenon of partial dry burning of the ultrasonic atomizing sheet.

Abstract
Description
- The present invention relates to electronic cigarettes, in particular to an ultrasonic atomizer and an e-liquid guide ceramic.
- Existing ultrasonic electronic cigarette atomizers generally guide e-liquid by means of direct communication of e-liquid guide cotton and an e-liquid cartridge. Using such e-liquid guide cotton will cause the following problems:
- 1. When the temperature of e-liquid in the e-liquid cartridge increases with the progress of ultrasonic atomization, the viscosity of e-liquid decreases, so that the flow rate of e-liquid on the e-liquid guide cotton rapidly increases, the e-liquid guide amount of the e-liquid guide cotton increases, and excessive e-liquid is supplied to the ultrasonic atomizing sheet, easily causing the problem that the ultrasonic atomizing sheet is soaked in e-liquid and other problems;
- 2. After the e-liquid guide cotton absorbs e-liquid, the pore size of the e-liquid guide cotton increases. When the temperature of the e-liquid increases with the progress of ultrasonic atomization and its viscosity decreases, the increase in the pore size of the e-liquid guide cotton also increases the e-liquid guide rate of the e-liquid guide cotton, which then easily causes the phenomenon that the ultrasonic atomizing sheet is soaked in the e-liquid, resulting in insufficient atomization of the e-liquid with the ultrasonic atomizing sheet and feeling of inhaling large smoke particles, so the user may feel himself/herselfinhaling e-liquid, with poor experience.
- In addition, when the ultrasonic atomizing sheet operates, the oscillation frequencies and intensities at different positions of the same ultrasonic atomizing sheet are different, that is, the efficiencies of atomizing e-liquid into smoke at different positions of the same ultrasonic atomizing sheet are different, so the phenomenon of partial dry burning easily occurs. For example, the atomization efficiency at the center of the ultrasonic atomizing sheet is the highest, so the e-liquid at the center of the ultrasonic atomizing sheet is easily consumed, resulting in dry burning at the center of the ultrasonic atomizing sheet. After the ultrasonic atomizing sheet operates for a period of time, when the e-liquid guide rate of the e-liquid guide cotton increases, the ultrasonic atomizing sheet is easily soaked in e-liquid; and when the ultrasonic atomizing sheet is restarted after being stopped for a period of time, the e-liquid guide rate of the e-liquid guide cotton decreases, and the phenomenon of dry burning easily occurs at the center of the ultrasonic atomizing sheet to affect the taste of smoke.
- The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art that the ultrasonic atomizing sheet is prone to partial dry burning or being soaked in e-liquid, and to provide an ultrasonic atomizer which has a stable e-liquid guide rate and can avoid the phenomenon that an ultrasonic atomizing sheet is partially burnt or soaked in e-liquid.
- In order to solve the above technical problems, the present invention provides an ultrasonic atomizer, including an e-liquid guide assembly, wherein the e-liquid guide assembly includes an e-liquid guide ceramic and e-liquid storing cotton, the lower surface of the e-liquid guide ceramic is configured as a rough surface which is uneven, the middle part of the rough surface is provided with a placement groove which is recessed, the e-liquid storing cotton is placed in the placement groove, the bottom surface of the e-liquid storing cotton is flush with the bottom surface of the rough surface, and both the rough surface and the e-liquid storing cotton are abutted against the middle part of an atomizing surface of an ultrasonic atomizing sheet, so that a partial e-liquid storing gap isformed at the place of contact of the rough surface and the ultrasonic atomizing sheet.
- E-liquid is guided by the e-liquid guide ceramic in the present invention, and the porosity of the e-liquid guide ceramic does not change with temperature changes, so the e-liquid guide rate is constant. In addition, the rough surface of the e-liquid guide ceramic is in contact with the atomizing surface of the ultrasonic atomizing sheet in the present invention, so that a partial e-liquid storing gap is formed at the place of contact of the rough surface and the ultrasonic atomizing sheet. E-liquid can be stored in these e-liquid storing gaps (that is, the e-liquid is in direct contact with the surface of the ultrasonic atomizing sheet), and the bottom surface of the e-liquid storing cotton which is placed in the placement groove is flush with the rough surface, so that the e-liquid on the rough surface can be absorbed by the e-liquid storing cotton and the e-liquid on the e-liquid storing cotton can be stored by the rough surface. When the ultrasonic atomizing sheet operates, the oscillation frequencies and intensities at different positions of the same ultrasonic atomizing sheet are different, that is, the efficiencies of atomizing e-liquid into smoke at different positions of the same ultrasonic atomizing sheet are different.Because the e-liquid storing cotton is in contact with the center of the ultrasonic atomizing sheet where the atomization efficiency is the highest, sufficient e-liquid can be supplied to the center of the ultrasonic atomizing sheet for ultrasonic atomization by means of the strong storage capacity of the e-liquid storing cotton.Even if the e-liquid on the e-liquid storing cotton is consumed, the e-liquid storing cotton can also quickly absorb e-liquid stored in the e-liquid storing gap of the rough surface, so as to ensure the timely replenishment of e-liquid on the e-liquid storing cotton and avoid the phenomenon of dry burning at the center of the ultrasonic atomizing sheet.In addition, the atomization efficiency at the place away from the center of the ultrasonic atomizing sheet is relatively lower than that at the center of the ultrasonic atomizing sheet. In the present invention, the rough surface of the e-liquid guide ceramic is in contact with the place away from of the center of the ultrasonic atomizing sheet to provide e-liquid required for atomization, and the e-liquid on the rough surface can be absorbed by the e-liquid storing cotton, so the place away fromthe center of the ultrasonic atomizing sheet can be prevented from being soaked in e-liquid to affect the atomization efficiency.
- Further, the middle part of the e-liquid guide ceramic is provided with an air outlet that axially penetrates the e-liquid guide ceramic, so that the e-liquid storing cotton is exposed at the bottom of the air outlet. When the ultrasonic atomizing sheet operates, the e-liquid on the ultrasonic atomizing sheet and the e-liquid storing cotton is ultrasonically atomized into smoke, and the smoke is carried out to the user's mouth by the air flowing into the air outlet through an air guide groove. During this process, the atomization efficiency at the center of the ultrasonic atomizing sheet is the highest. Because the e-liquid storing cotton is directly in contact with the center of the ultrasonic atomizing sheet and communicated with the air outlet (that is, the e-liquid storing cotton is exposed at the bottom of the air outlet), the e-liquid on the e-liquid storing cotton can be atomized as soon as possible, and the atomized smoke can be directly discharged to the air outlet channel through the air outlet without being blocked, so that not only can the smoke flow into the air outlet channel at the fastest speed, but also the smoke can be carried out thoroughly. In addition, the side wall of the air outlet is relatively long; and when smoke passes through the air outlet, the smoke hits the side wall of the air outlet, and the ceramic on the side wall of the air outlet absorbs large-particle e-liquid droplets, thereby preventing the user from inhaling e-liquid droplets and improving the taste of smoke.
- Further, the lower surface of the e-liquid guide ceramic is provided with an air guide groove, and the air guide groove is communicated with the bottom of the air outlet, so that air flow can carry the smoke generated by the ultrasonic atomization of the ultrasonic atomizing sheet out to the air outlet.
- Further, a plurality of air guide grooves are radially distributed on the lower surface of the e-liquid guide ceramic, so that air flows into the air outlet from all directions of the atomizing surface of the ultrasonic atomizing sheet, to carry the smoke generated at all positions of the atomizing surface of the ultrasonic atomizing sheet into the air outlet. Further, an e-liquid storing cavity is formed around the periphery of the air outlet, so that the distance between the e-liquid and the ultrasonic atomizing sheet is relative short, and the time for the e-liquid guide ceramic to guide the e-liquid to the ultrasonic atomizing sheet is relative short. Therefore, when the ultrasonic atomizing sheet operates, the e-liquid guide ceramic can quickly supply e-liquid to the ultrasonic atomizing sheet, to ensure continuous ultrasonic atomization on the ultrasonic atomizing sheet, so that each puff of smoke inhaled by the user is equal and the smoke tastes better.
- Further, a plurality of reinforcing ribs are arranged in the e-liquid storing cavity, and the reinforcing ribs are radially distributed on the periphery of the air outlet, where the reinforcing ribs support the side wall of the air outlet to increase the strength of the overall structure of the e-liquid guide ceramic.
- Further, the vertical distance between the bottom surface of the e-liquid storing cavity and the ultrasonic atomizing sheet is 0.5 mm to 8 mm. Because the distance between the bottom surface of the e-liquid storing cavity and the ultrasonic atomizing sheet is related to the transfer rate of e-liquid: the shorter the distance, the shorter the e-liquid transfer time, and the faster the e-liquid transfer; and the longer the distance, the longer the e-liquid transfer time, and the slower the e-liquid transfer. Therefore, the purpose of controlling the e-liquid transfer time and e-liquid transfer rate can be achieved by controlling the distance between the bottom surface of the e-liquid storing cavity and the ultrasonic atomizing sheet. In the present invention, the vertical distance between the bottom surface of the e-liquid storing cavity and the ultrasonic atomizing sheet is 0.5 mm to 8 mm, so that e-liquid can be transferred to the ultrasonic atomizing sheet by the e-liquid guide ceramic in time, while the ultrasonic atomizing sheet is not soaked in the e-liquid, thereby avoiding dry burning of the ultrasonic atomizing sheet due to little e-liquid, and avoiding the phenomenon that the ultrasonic atomizing sheet is soaked in e-liquid due to excessive e-liquid.
- Further, the ultrasonic atomizer includes an e-liquid storing assembly with an e-liquid cartridge and an atomizing assembly, the e-liquid guide assembly and the atomizing assembly are sequentially installed at the bottom of the e-liquid storing assembly, an air outlet channel communicated with a suction nozzle is provided in the e-liquid storing assembly, an air inlet channel communicated with outside air is provided in the atomizing assembly, and the air inlet channel is communicated with the air outlet channel through the air guide groove and the air outlet on the e-liquid guide ceramic. Based on the same inventive concept, the present invention provides an e-liquid guide ceramic, the lower surface of the e-liquid guide ceramic is configured as a rough surface which is uneven, and the middle part of the rough surface is recessed to form a placement groove for placing the e-liquid storing cotton.
- When the e-liquid guide ceramic of the present invention is used, the rough surface of the e-liquid guide ceramic is in contact with the ultrasonic atomizing sheet, so that partial e-liquid storing gaps are formed at the place of contact of the rough surface and the ultrasonic atomizing sheet. E-liquid can be stored in these e-liquid storing gaps (that is, the e-liquid is in direct contact with the surface of the ultrasonic atomizing sheet), and the bottom surface of the e-liquid storing cotton placed in the placement groove is flush with the rough surface, so that the e-liquid on the rough surface can be absorbed by the e-liquid storing cotton, and the e-liquid on the e-liquid storing cotton can be stored by the rough surface. The oscillation frequencies and intensities at different positions of the same ultrasonic atomizing sheet are different, that is, the efficiencies of atomizing e-liquid into smoke at different positions of the same ultrasonic atomizing sheet are different. Meanwhile, the e-liquid storing cotton has relatively strong capacity of storing e-liquid, that is, the e-liquid storing cottonstores much e-liquid, while the e-liquid guide ceramic stores a little e-liquid, so the e-liquid storing cotton and the rough surface respectively abut against different positions of the ultrasonic atomizing sheet to avoid the phenomenon of partial dry burning of the ultrasonic atomizing sheet. For example, when the atomization efficiency at the center of the ultrasonic atomizing sheet is the highest, the e-liquid storing cotton abuts against the center of the ultrasonic atomizing sheet, so the e-liquid storing cotton supplies enough e-liquid to produce atomized e-liquid required for each puff. If the e-liquid on the e-liquid storing cotton is easily consumed, the e-liquid stored in the gaps of the rough surface can be quickly absorbed by the e-liquid storing cotton, which can ensure the timely replenishment of e-liquid on the e-liquid storing cotton.
- Compared with the prior art, the present invention has the following beneficial effects:
- 1. The rough surface of the e-liquid guide ceramic of the present invention is in contact with the ultrasonic atomizing sheet, so that partial e-liquid storing gaps are formed at the place of contact of the rough surface and the ultrasonic atomizing sheet. E-liquid can be stored in these e-liquid storing gaps (that is, the e-liquid is in direct contact with the surface of the ultrasonic atomizing sheet), and the bottom surface of the e-liquid storing cotton placed in the placement groove is flush with the rough surface, so that the e-liquid on the rough surface can be absorbed by the e-liquid storing cotton, and the e-liquid on the e-liquid storing cotton can be stored by the rough surface. The oscillation frequencies and intensities at different positions of the same ultrasonic atomizing sheet are different, that is, the efficiencies of atomizing e-liquid into smoke at different positions of the same ultrasonic atomizing sheet are different, which can avoid the phenomenon of partial dry burning of the ultrasonic atomizing sheet, and achieve supply and demand balance of e-liquid when the ultrasonic atomizing sheet operates or stops.
- 2. E-liquid is guided by the combination of the e-liquid guide ceramic and the e-liquid storing cotton, the e-liquid guide ceramic is directly connected with the e-liquid in the e-liquid cartridge and transfers the e-liquid to the ultrasonic atomizing sheet and the e-liquid storing cotton, and the e-liquid storing cotton only plays a role of e-liquid storage, so the e-liquid guide amount of the e-liquid guide assembly is constant during the ultrasonic atomization, and the ultrasonic atomizing sheet will not be soaked in the e-liquid, which ensures the ultrasonic atomization efficiency and achieves stable smoke amount.
- 3. The center of the e-liquid guide ceramic of the present invention is provided with an air outlet penetrating the e-liquid guide ceramic, the e-liquid storing cotton is exposed at the bottom of the air-outlet, the lower surface of the e-liquid guide ceramic is provided with an air guide groove, the air guide groove is communicated with the bottom of the air outlet, and the air flow can pass by the upper surfaces of the ultrasonic atomizing sheet and the e-liquid storing cotton, so that smoke can be carried out thoroughly and in time.

- The present invention will be further described below with reference to specific preferred embodiments, but the scope of protection of the present invention is not limited thereby.
- For the convenience of description, the relative positional relationships of components, such as upper, lower, left, and right, are described according to the layout directions of the drawings in the specification, and do not limit the structure of this patent.
- As shown in
FIGS. 1 to 6 , an ultrasonic atomizer of this embodiment includes ane-liquid storing assembly 1, ane-liquid guide assembly 2 and anatomizing assembly 3. Thee-liquid guide assembly 2 and theatomizing assembly 3 are sequentially installed at the bottom of thee-liquid storing assembly 1. - The
e-liquid storing assembly 1 includes ahousing 11 and aplug 12 connected to each other. Ane-liquid cartridge 13 is formed byconnecting the housing 11with theplug 12. Theplug 12 is preferably an elastic silica gel plug. - The
e-liquid guide assembly 2 includes an e-liquid guide ceramic 21 ande-liquid storing cotton 22. Thee-liquid storing cotton 22 has a thickness of 0.1 to 1.0 mm. - The middle part of the lower surface of the e-liquid guide ceramic 21 is provided with a
placement groove 211, theplacement groove 211 has the same size as thee-liquid storing cotton 22, and the surface roughness of the placement groove is Ra0.5 to Ra3.5. When thee-liquid storing cotton 22 is placed in theplacement groove 211, the friction force between the e-liquid storingcotton 22 and theplacement groove 211 is relatively large, so thee-liquid storing cotton 22 is placed more firmly. The lower surface of the e-liquid guide ceramic 21 is also configured as arough surface 212, the roughness of therough surface 212 is Ra0.1 to Ra7.5, and therough surface 212 can be polished with small holes or small grooves to form an uneven surface, so that when therough surface 212 is in contact with theultrasonic atomizing sheet 322, certain e-liquid storing gaps that can store e-liquid are formed. Both thee-liquid storing cotton 22 and therough surface 212 are abutted against an atomizing surface of theultrasonic atomizing sheet 322, so that there is e-liquid on the atomizing surface of theultrasonic atomizing sheet 322. - The center of the e-liquid guide ceramic 21 is provided with an
air outlet 214 penetrating thee-liquid guide ceramic 21. The diameter of theplacement groove 211 is greater than that of theair outlet 214, so a part of thee-liquid storing cotton 22 is exposed at the bottom of theair outlet 214 and is not blocked. Therefore, when theultrasonic atomizing sheet 322 operates, e-liquid is atomized to produce a largest amount of smoke with the fastest speed at this part. The other part of thee-liquid storing cotton 22 is abutted against theultrasonic atomizing sheet 322 by theplacement groove 211, which prevents thee-liquid storing cotton 22 from skewing or wrinkling to affect the e-liquid guide effect after thee-liquid storing cotton 22 is in contact with theultrasonic atomizing sheet 322. A plurality ofair guide grooves 213 are radially distributed on the lower surface of the e-liquid guide ceramic 21, and theair guide grooves 213 penetrate therough surface 212 and theplacement groove 211 until theair guide grooves 213 are communicated with the bottom of theair outlet 214. When air flows through theair guide grooves 213, the air flow will bring the smoke generated from the surface of therough surface 212 and the surface of thee-liquid storing cotton 22 in theplacement groove 211 into theair outlet 214, and finally the smoke is inhaled by a user. - An
e-liquid storing cavity 215 is formed in the e-liquid guide ceramic 21, and thee-liquid storing cavity 215 is formed around the periphery of theair outlet 214. After the e-liquid guide ceramic 21 is assembled with thee-liquid storing assembly 1, thee-liquid storing cavity 215 is communicated with thee-liquid cartridge 13, that is, e-liquid is stored in thee-liquid storing cavity 215, so that the direct contact area between the e-liquid and the e-liquid guide ceramic 21 is relative large, thereby increasing the e-liquid guide rate of thee-liquid guide ceramic 21. A reinforcingrib 216 is arranged inside thee-liquid storing cavity 215, which can not only increase the contact area between the e-liquid guide ceramic 21 and the e-liquid, but also make the internal structure of the e-liquid guide ceramic 21 stronger, facilitate assembly, and improve assembly efficiency and yieldrate. - The vertical distance between the bottom end of the
e-liquid storing cavity 215 and theultrasonic atomizing sheet 322 is 0.5 mm to 8 mm, so that the e-liquid in thee-liquid storing cavity 215 is as close as possible to the atomizing surface of theultrasonic atomizing sheet 322. However, the time required for the e-liquid guide ceramic 21 to transfer the e-liquid to the atomizing surface of theultrasonic atomizing sheet 322 is short. Therefore, the shorter the vertical distance between the bottom end of thee-liquid storing cavity 215 and theultrasonic atomizing sheet 322 is, the faster the transfer of e-liquid is; and the longer the distance is, the slower the transfer of e-liquid is. When theultrasonic atomizing sheet 322 operates, the shorter the e-liquid supply distance is, the faster the e-liquid supply is,to avoid dry burning of theultrasonic atomizing sheet 322 and to achieve more stable smoke amount. - The
atomizing assembly 3 includes abottom cover 31 made of a conductive material, and anatomizing head 32 arranged in thebottom cover 31. - The atomizing
head 32 includes a conductivehollow atomizing sleeve 321, and theultrasonic atomizing sheet 322 and aninsulating seat 323 are sequentially arranged in the inner cavity of theatomizing sleeve 321 from top to bottom. Anelectrode assembly 324 is arranged at the middle part of the insulatingseat 323. The upper end of theatomizing sleeve 321 is connected to an upper surface electrode of theultrasonic atomizing sheet 322 in an abutting manner, the lower end of theatomizing sleeve 321 is covered at the bottom of the insulatingseat 323 as a first electrode connection terminal, a lower surface electrode of theultrasonic atomizing sheet 322 is electrically connected to theelectrode assembly 324, and theelectrode assembly 324 serves as a second electrode terminal. - Both of the
rough surface 212 of the e-liquid guide ceramic 21 and thee-liquid storing cotton 22 are placed on theultrasonic atomizing sheet 322. Anair outlet channel 14 is provided in thee-liquid storing assembly 1, theatomizing assembly 3 is provided with anair inlet channel 33, and theair inlet channel 33 is communicated with theair outlet channel 14 through theair guide groove 213 and theair outlet 214 on thee-liquid guide ceramic 21. - When this embodiment is used, the user inhales from a suction nozzle of the
air outlet channel 14 of thee-liquid storing assembly 1, making outside air enters from theair inlet channel 33 into theair outlet channel 14 through theair guide groove 213 and theair outlet 214 on the e-liquid guide ceramic 21.E-liquid is transferred from the e-liquid cartridge 13to the ultrasonic atomizing sheet 322throughthe e-liquid guide assembly 2.Theultrasonic atomizing sheet 322 is electrically connected to an external power supply through theatomizing sleeve 321 and theelectrode assembly 324 to implement ultrasonic atomization, and smoke on theultrasonic atomizing sheet 322 and thee-liquid storing cotton 22 which is generated by ultrasonic atomization is carried out by the air flow to pass through theair outlet 214 and theair outlet channel 14 and enter to the user's mouth and is inhaled. - The forgoing descriptions are only preferred embodiments of the present application, and do not limit the present application in any form.
