Description

Technical Field

[0001] The present invention relates to an atomizing device, and more particularly to an electronic atomizing device and an atomizer and a liquid discharge control mechanism thereof. Background Art

[0002] The liquid atomizing medium of the electronic atomizing device in the related technology is generally controlled by gravity and the capillary tension of the heating component. After the user unpacks the package for use, the heating component is connected to the outside air. During use, the aroma and flavor of the liquid atomizing medium will gradually evaporate over time. When the temperature of the electronic atomizing device rises during atomization, the volatilization of the aroma and flavor will be accelerated, making the taste of the liquid atomizing medium inconsistent before and after inhalation, and the aroma in the later stage will be significantly reduced. As the amount of liquid atomizing medium in the electronic atomizing device increases, the aroma restoration degree before and after will be significantly different.

Of course, it can be understood that in some other embodiments, the heating structure 232 may not be limited to a heating wire or a heating film.

[0051] Further, in some embodiments, the atomization assembly 20 further includes a liquid absorbing member 24, which can be a liquid absorbing cotton, which can be arranged in the atomization seat 22 and located on the side of the porous body 231 opposite to the heating structure 232, and the liquid atomization medium transported from the second liquid storage chamber 2223 can be stored by the liquid absorbing member 24 and output to the porous body 231.

[0052] Further, in some embodiments, the atomization assembly 20 further includes a first seal 25, which is sleeved on the atomization seat 22.

[0055] Further, in some embodiments, the liquid lowering control mechanism 30 may include a blocking member 31 and a driving assembly 32. In some embodiments, the blocking member 31 may be disposed in the first liquid storage chamber 13. Of course, it can be understood that in other embodiments, the blocking member 31 may not be limited to being disposed in the first liquid storage chamber 13. The driving assembly 32 may be connected to the blocking member 31, and may be driven by the blocking member 31 to move in a first direction to block the second liquid storage chamber 2223, or to move in a second direction to open the second liquid storage chamber 2223. In some embodiments, the first direction may be a direction toward the atomizer seat 22, and the second direction may be a direction away from the atomizer seat 22.

[0056] Further, in some embodiments, the liquid lowering control mechanism 30 may include a blocking member 31 and a driving assembly 32. The blocking member 31 may be disposed in the first liquid storage chamber 13, and may reciprocate along the liquid lowering direction of the first liquid storage chamber 13, thereby isolating the first liquid storage chamber 13 and the second liquid storage chamber 2223 or connecting the first liquid storage chamber 13 and the second liquid storage chamber 2223. The driving assembly 32 may be mounted on the atomizing seat 22, and may be connected to the blocking member 31. The driving assembly 32 may drive the blocking member 31 to move along the first direction, thereby isolating the first liquid storage chamber 13 and the second liquid storage chamber 2223, that is, it may move along the direction close to the atomizing seat 22 to isolate the first liquid storage chamber 13 and the second liquid storage chamber 2223, specifically, it may move downward along the axial direction of the lower liquid hole 2222, thereby isolating the first liquid storage chamber 13 and the second liquid storage chamber 2223. In some embodiments, the driving component 32 can drive the sealing member 31 to move in the second direction, thereby connecting the first liquid storage chamber 13 and the second liquid storage chamber 2223; that is, it can move in a direction away from the atomizer seat 22, thereby connecting the first liquid storage chamber 13 with the second liquid storage chamber 2223, and then the liquid atomization medium in the first liquid storage chamber 13 can be transported from the second liquid storage chamber 2223 to the heating component 23. Specifically, the sealing member 31 can move upward along the axial direction of the lower liquid hole 2222 so that the first liquid storage chamber 13 is connected to the lower liquid hole 2222.

[0057] Further, in some embodiments, the blocking member 31 may include a sealing portion 311, and the sealing portion 311 may be substantially elliptical. Of course, it can be understood that in some other embodiments, the sealing portion 311 may not be limited to being elliptical. The sealing portion 311 can be used to cover the two lower liquid holes 2222; in some embodiments, the sealing portion 311 is provided with an avoidance hole 3111; the avoidance hole 3111 can be arranged corresponding to the vent hole 2221 of the atomizer seat 22. The avoidance hole 3111 can be located at the center of the sealing portion 311. In some embodiments, the blocking member 31 may also include a positioning portion 312, which may be protrudingly arranged on a side of the sealing portion 311 opposite to the atomizer seat 22, and one of the lower liquid holes 2222 is arranged correspondingly. When the sealing portion 311 seals the two lower liquid holes 2222, the positioning portion 312 can be inserted into the corresponding lower liquid hole 2222, thereby playing a role in positioning and fixing. In some embodiments, the positioning portion 312 may be columnar. Of course, it is understandable that in some other embodiments, the positioning portion 312 may not be limited to a columnar shape. In some embodiments, the blocking member 31 further includes a connecting portion 313, which may be arranged on the sealing portion 311. Specifically, it may be located on the side of the sealing portion 311 that is opposite to the positioning portion 312. The connecting portion 313 may be columnar, and a connecting through hole 3131 is provided on the inner side thereof, and the connecting through hole 3131 may be plugged into the push rod 321 of the driving assembly 32. In some embodiments, the blocking member 31 may be a sealing silicone. Of course, it is understandable that in some other embodiments, the blocking member 31 may not be limited to a silicone material.

[0058] Further, in some embodiments, the drive assembly 32 may include a push rod 321 and a drive structure 322. The push rod 321 may be connected to the blocking member 31, and both ends may pass through the through hole 2224 of the atomizer seat 22. Specifically, the push rod 321 may be inserted into the connecting through hole 3131 of the connecting portion 313. In some embodiments, the push rod 321 may form an integral structure with the blocking member 31. Specifically, the push rod 321 may form an integral structure with the blocking member 31 by injection molding. Of course, it is understandable that in some other embodiments, the push rod 321 is not limited to being formed into an integral structure by injection molding with the blocking member 31. In some embodiments, the drive structure 322 is connected to the push rod 321, and specifically, a section of the push rod 321 passing through the lower part of the atomizer seat 22 is provided with an annular groove 3211, and the groove 3211 can be used to connect the drive structure 322. The driving structure 322 can drive the push rod 321 to reciprocate along the axial direction of the through hole 2224 , thereby isolating or connecting the first liquid storage chamber 13 and the second liquid storage chamber 2223 .

[0059] Further, in some embodiments, in some embodiments, the drive structure 322 can be installed in the lower part of the atomizing seat 22, and is located between the atomizing seat 22 and the atomizing base 21, and can be clamped and fixed by the atomizing seat 22 and the atomizing base 21. Specifically, the drive structure 322 can be installed in the atomizing chamber 2210, and is located below the heating component 23, and a set distance is set between the heating component 23. Specifically, the drive structure 322 can be located below the heating structure 232, and the distance between the heating structure 232 is set to within 3mm, which can facilitate the heat deformation of the drive structure 322. It is understandable that in some other embodiments, the set distance may not be limited to less than 3mm. Of course, it is understandable that in some other embodiments, the drive structure 322 may also be located above the heating component 23, and a set distance may be set between the heating component 23. Of course, it can be understood that in some other embodiments, the driving structure 322 may not be limited to being set in the atomization chamber 2210, and may not be limited to being set in the atomization shell 10. The driving structure 322 may be extended from the atomization shell 10 or the atomization base 21, or directly set on the outside of the atomization shell 10 or the atomization base 21.

[0060] like Figure 6As shown, further, in some embodiments, the drive structure 322 may include at least one elastic sheet, specifically, it may include two elastic sheets, the elastic sheet may include a first elastic sheet 3221, the first elastic sheet 3221 may be in the shape of a longitudinal sheet, the first elastic sheet 3221 may be installed in the atomization chamber 2210, and may be located below the heating component 23, and a set distance is set with the heating component 23, and the set distance may be greater than zero and less than three millimeters. In some embodiments, the first elastic sheet 3221 may be connected to the push rod 321, specifically, the end of the first elastic sheet 3221 may be connected to the slot 3211 of the push rod 321, and may abut against the upper end wall of the slot 3211. In some embodiments, the first elastic sheet 3221 may be a metal sheet susceptible to thermal deformation. When the heating component 23 is heated to the first set temperature, the first elastic sheet 3221 may be deformed by heat, driving the push rod 321 to move in the second direction to connect the first liquid storage chamber 13 and the second liquid storage chamber 2223. Specifically, when the heating component 23 is heated to the first set temperature, the first elastic sheet 3221 may be bent, and its end may be tilted toward the side close to the heating component 23, thereby moving the push rod 321 in the second direction (away from the atomizer seat 22), so that the first liquid storage chamber 13 can be connected with the second liquid storage chamber 2223. When the heating component stops heating and cools to the second set temperature, or the electronic atomization device places the heating component at or below the second set temperature, the first elastic sheet 3221 may be reset to drive the push rod 321 to move in the first direction (moving in the direction close to the atomizer seat 22) to separate the first liquid storage chamber 13 and the second liquid storage chamber 2223. Specifically, when the heating component 23 is at or below the second set temperature, the end of the first elastic sheet 3221 can be bent toward the side away from the heating component 23 and restored, so that it can abut against the lower end wall of the slot 3211, and then drive the push rod 321 to move in the first direction, driving the blocking member 31 to block the lower liquid hole 2222. Among them, the first set temperature and the second set temperature can be the same. Of course, it can be understood that in some other embodiments, the first set temperature and the second set temperature can also be different. In some embodiments, the first set temperature and the second set temperature can preferably be 60 degrees.

[0061] When the liquid atomized medium is stored, because the temperature used is lower than the operating temperature of the first elastic sheet 3221 (lower than 60 degrees), the blocking member 31 is always in a closed state, and the blocking member 31 can seal the lower liquid hole 2222, and the liquid atomized medium cannot flow out of the first liquid storage chamber 13. When the user inhales, the heating structure 232 on the heating component 23 generates heat, and the temperature in the atomization chamber 2210 rises to 60 degrees, and the first elastic sheet 3221 is deformed, thereby moving the push rod 321 to drive the blocking member 31 upward, so that the liquid atomized medium can flow from the first liquid storage chamber 13 to the lower liquid hole 2222.

[0062] Furthermore, in some embodiments, the elastic sheet further includes a second elastic sheet 3222; the second elastic sheet 3222 can be used for mounting and positioning the first elastic sheet 3221, one end of which can be connected to the first elastic sheet 3221 and stacked with the first elastic sheet 3221. In some embodiments, the second elastic sheet 3222 can be disposed in the atomizing chamber 2210 and clamped and fixed by the atomizing seat 22 and the atomizing base 21.

[0063] In some embodiments, the first elastic sheet 3221 and the second elastic sheet 3222 may have the same structure. The elastic sheet may include a sheet-like body 322a and a positioning protrusion 322b; the sheet-like body 322a may be roughly elliptical; of course, it can be understood that in some other embodiments, the sheet-like body 322a may not be limited to being elliptical. One end of the first elastic sheet 3221 may be connected to the sheet-like body 322a of the second elastic sheet 3222, and the other end may form a free end for moving the push rod 321. The positioning protrusion 322b may be arranged at one end of the long axis of the sheet-like body 322a, and it may be arranged to protrude along the long axis direction. The positioning protrusion 322b may be used for positioning the push rod 321. In some embodiments, the positioning protrusion 322b is provided with a positioning bayonet 322c, and the positioning bayonet 322c may be opened in the long axis direction of the sheet-like body 322a, and the positioning bayonet 322c may be inserted into the push rod 321. The width dimension of the positioning bayonet 322c may be larger than the outer diameter of the push rod 321, so as to facilitate the axial reciprocating motion of the push rod 321 along the lower liquid hole 2222. In some embodiments, an airflow hole 322d may be provided on the sheet body 322a; the airflow hole 322d may be located in the middle of the sheet body 322a, and may be provided through the thickness direction of the sheet body 322a. There may be multiple airflow holes 322d, and the airflow holes 322d may allow the airflow of the air inlet hole 2111 to enter the atomizing chamber 2210. In some embodiments, a through hole 322e may be provided on the sheet body 322a, and there may be two through holes 322e, and the two through holes 322e may be provided at intervals and located on both sides of the airflow hole 322d, and the two through holes 322e may allow the electrode 27 to pass through, and they may be provided one-to-one with the electrode 27. In some embodiments, a square hole 322f may be further provided on the sheet body 322a; the square hole 322f may be located between the through hole 322e and another through hole 322e, and may be used for the support arm 2121 on the atomizing base 21 to pass through.

[0064] The driving structure 322 is a bimetallic structure. During thermal deformation, the driving structure 322 is similar to the suction action of a water pump valve, which can better vibrate the liquid. The driving structure 322 can drive the blocking member 31 to achieve intelligent liquid discharge and automatically adapt to the user's suction habits. One end of the first elastic sheet 3221 can be connected to a side of the through hole 322d provided with the positioning protrusion 322b away from the second elastic sheet 3222; the first elastic sheet 3221 is more susceptible to thermal expansion than the second elastic sheet 3222; the first elastic sheet 3221 produces the maximum deformation size. In some embodiments, the material of the first elastic sheet 3221 and the second elastic sheet 3222 can be selected as an iron-nickel-manganese-copper alloy. It can be understood that in some other embodiments, the material of the first elastic sheet 3221 and the second elastic sheet 3222 is not limited to an iron-nickel-manganese-copper alloy. It can be understood that in some other embodiments, the second elastic sheet 3222 can be omitted.

[0065] Further, in some embodiments, the driving structure 322 may be one, and of course, it can be understood that in other embodiments, the driving structure 322 may not be limited to one, and in other embodiments, the driving structure 322 may be multiple, and the multiple driving structures 322 may be arranged side by side and at intervals along the movement direction of the push rod 321. By providing multiple driving structures 322, the support force on the push rod 321 can be increased, and the deformation tension can be increased.

[0066] In some other embodiments, the blocking member 31 may also be manually driven to open or close the second liquid storage chamber 2223. Specifically, the driving assembly 32 may be a manually driven structure, which may include a pressing structure, which may be arranged to pass through the electronic atomization device, that is, pass through the atomization shell 10, and may be connected to the blocking member 31. By pressing the pressing structure, the blocking member 31 may be pushed to open the second liquid storage chamber 2223, and loosening the blocking member 31 may reset the blocking member 31 to seal the second liquid storage chamber 2223. In some embodiments, the blocking member 31 may be a wedge-shaped block.

[0067] In some other embodiments, the blocking member 31 may also be designed to be pushed open upwards, the first elastic sheet 3221 and the second elastic sheet 3222 may be reversed, the first elastic sheet 3221 may be located below the second elastic sheet 3222, and the first elastic sheet 3221 may be deformed by bending upwards, thereby driving the blocking member 31 to open the second liquid storage chamber 2223.

[0068] The liquid discharge method of the liquid discharge control mechanism of the present invention separates the liquid atomized medium in the atomization area from the liquid atomized medium in the first storage chamber 13 through the blocking member 31 to separate the first storage chamber 13 and the second storage chamber 2223, so as not to affect the concentration of the aroma and flavor of the liquid atomized medium. During storage, the first storage chamber 13 and the second storage chamber 2223 are in a closed state (the two storage chambers do not flow and affect each other). When the user sucks, the atomization chamber 2210 first sucks the liquid atomized medium in the second storage chamber 2223. When the temperature in the second storage chamber 2223 reaches the first set temperature (i.e., the temperature that can cause the driving structure of the liquid discharge control mechanism to operate), the driving structure automatically pushes open the blocking member 31 to realize intelligent automatic liquid discharge, i.e., the liquid atomized medium flows from the first storage chamber 13 to the second storage chamber 2223, so that the taste of the electronic atomization device is consistent before and after suction. It can also ensure that the liquid atomized medium can be sealed in the first liquid storage chamber 13 when the electronic atomization device is stored. When the user takes a half-inhalation and puts it aside, when the temperature difference or air pressure changes (flying on an airplane), the liquid atomized medium in the first liquid storage chamber 13 will not leak out. When the electronic atomization device is produced, the first liquid storage chamber 13 and the second liquid storage chamber 2223 are both filled with liquid, so as to prevent the atomization chamber 2210 from being dry-burned.

[0069] It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the coverage of the claims of the present invention.
