Description

[Technical field]

[0001] The present invention relates generally to atomizers, and more particularly to an atomization module and an electronic atomization device including an atomization module. [Background technology]

[0002] In the present invention, atomization refers to the process of atomizing a liquid into an aerosol so that a person can inhale it through the mouth or nose. Atomization is widely used in e-cigarettes, medical products, entertainment products, etc., but traditional atomization devices generally have the following problems: - The liquid flow passage of the liquid storage chamber is too long and narrow, which easily causes the problem of insufficient supply of atomized liquid. - The nebulizer touches the battery rod, which is prone to oxidation and becoming covered with liquid condensation after long-term use, resulting in poor electrical contact. The nebulizer is also unstable and prone to shaking. - The air passage is not rationally designed, which affects the user experience. The atomizer and the battery rod do not form a closed air passage. When the atomized aerosol is exchanged with the outside air, the gap between the atomizer and the battery rod is prone to producing noise. - The atomization chamber is too large and does not match the front and rear air passages, which results in the aerosol not being able to leave the chamber effectively during use and excessive condensation. Since the oil cup and the atomizing assembly are sealed by interference fit and there is no guide groove therebetween, it is difficult to assemble the oil cup with the atomizing assembly.

[0022] The implementation of the present invention is described by the following specific embodiments, and those skilled in the art can easily understand other advantages and effects of the present invention from the details disclosed herein. The present invention can also be implemented or applied in other different ways, and the details of the present specification can be modified or changed in various ways based on different perspectives and applications without departing from the spirit of the present invention.

[0023] Please refer to the attached drawings. It should be noted that the drawings provided in this embodiment are only for explaining the basic concept of the present invention, so the drawings only show the parts related to the present invention, and do not show the number, size and shape of the parts actually implemented. The types, numbers and proportions of the parts actually implemented can be changed randomly, and the pattern of the arrangement of the parts can also be more complicated. Unless specified, the terms "upper", "lower", "left" and "right" used in this specification are all from the perspective of the person who sees the attached drawings.

[0024] The atomizing device of the present invention includes a liquid storage chamber, an atomizing element, and other main components, and is used to form a complete atomizing device after being assembled with a battery rod. The battery rod generally refers to a part of the atomizing device other than the atomizing device, and one of its functions is to supply power to the atomizing device after being combined with the atomizing device. Since the battery rod is not a novelty of the present invention, the structure of the battery rod is not described here.

[0025] Please refer to Fig. 1, which is an exploded view of one embodiment of the present invention. The atomizing device 1 includes an outer shell 11 and a bottom cover 12. The outer shell 11 is composed of two parts. The upper part is a suction nozzle 111, and the lower part is an assembly 112. The suction nozzle 111 is an outlet for the aerosol for the user to inhale directly into the mouth, nose, or other types of inhalers. The assembly 112 is used to connect to a battery rod (not shown).

[0026] In this embodiment, the outer diameter of the assembly part 112 is slightly smaller than the joint between the upper and lower parts of the nebulizer 1, so that the nebulizer 1 is inserted into the battery rod. Preferably, a sealing ring 113 is provided at the joint between the upper and lower parts of the outer shell 11, forming an airtight seal between the nebulizer 1 and the battery rod to prevent air leakage. Therefore, the outside air can be thoroughly mixed with the nebulizer liquid, and problems such as abnormal noise and low sensitivity of the air pressure switch due to leakage from the gap are avoided, the connection between the nebulizer and the battery rod is stable, and the shaking of the nebulizer after assembly is avoided. The outer shell 11 and the bottom cover 12 define an internal cavity that encloses the nebulizer element, the reservoir chamber, the air passage, etc. For illustration of each part, please refer to the following Figures 2a and 2b.

[0027] 2a is a longitudinal cross-sectional view along the line AA in the embodiment of FIG. 1 in an assembled state. There is an air passage 13 in the cavity, and the upper part of the air passage is connected to the suction nozzle, and a liquid storage chamber 14 for storing the atomized liquid is formed between the outer wall of the air passage 13 and the outer shell 11. The atomizing element bracket 3 is provided below the air passage 13, has a convex shape like a convex, and has an opening 31 at its top. The opening 31 communicates with the air passage 13 to form an airtight connection. For example, a silica gel pad is provided on the upper part of the bracket 3, and the silica gel pad contacts the lower part of the air passage 13 to form an airtight connection. The atomizing element mounting groove is provided below the bracket 3 to accommodate the atomizing element assembly 4. The shoulder of the convex-shaped bracket 3 forms an inlet 32 ​​of the atomized liquid flow path and is connected to the atomizing element assembly 4, so that the atomized liquid in the liquid storage chamber 14 can directly reach the atomizing element assembly 4. The atomized liquid is highly viscous because it is mainly composed of PG (propylene glycol) and VG (vegetable glycerin). The convex atomizing element bracket 3 widens the entrance of the atomized liquid flow path, shortens the atomized liquid flow path, and improves the passing capacity of the atomized liquid, which can reduce the problem of insufficient liquid supply compared to the conventional flat design.

[0028] Preferably, the inner wall of the outer shell 11 is set in a structure with a small upper end and a large lower end, and the inner diameter of the outer shell above the boundary surface 114 is smaller than the inner diameter below the boundary surface 114. Such a design plays a role of a guide in the assembly of the atomizing element bracket 3 and the bottom cover 12, making the assembly easier and more conducive to providing a sealing structure and forming a seal. FIG. 3 shows an embodiment structure of the atomizing element assembly 4 of the present invention, which includes a sealing sleeve 41, a straightening cotton 43, and a heating unit 44. The heating unit 44 is provided below the straightening cotton 43, contacts the straightening cotton 43, and is tightly fitted with the cotton, heating the atomized liquid in the straightening cotton 43 to atomize the liquid. The sealing unit 41 can be made of silica gel, covers the straightening cotton 43 and the heating unit 44, seals the atomizing element bracket at the top, and has an inlet 411 for the atomized liquid. The sealing unit 41 allows the atomized liquid to reach the lower straightening cotton 43 only through the atomized liquid inlet 411. Preferably, a rigid middleware 42 is provided between the upper sealing sleeve 41 and the lower straightening cotton 43 to ensure that the upper sealing sleeve 41 and the lower straightening cotton 43 are flat and not deformed.

[0029] The electrode 5 is provided below the atomizing element assembly 4 and is attached on the bottom cover 12. For details of their structure and assembly relationship, please refer to Figure 4. Figure 4 is an exploded view of the bottom cover 12, the electrode 5 and related parts.

[0030] In order to make the atomizing element bracket more stable, a buckle hole 123 may be provided on the side wall of the bottom cover 12, and the buckle hole 123 matches with the buckle hole 3b2 (see FIG. 6) of the atomizing element bracket 3 when installed. The electrode 5 adopts a crown spring terminal, and the crown spring terminal includes a cavity 51 therein, and the cavity 51 includes a crown spring 52. The crown spring 52 protrudes inward and can be elastically deformed outward. When the electrode 5 including the crown spring terminal is fitted with the electrode in the battery rod, the contact area is larger and the contact is tighter than the contact point, so that the poor contact of the electrode can be avoided and the reliability can be improved. The terminal 5 and the mounting hole 125 of the bottom cover 12 form an interference fit with the lower part of the terminal 5 and are connected with the bottom cover 12 by riveting pressure. After installation, the lower part of the terminal 5 is flush with the lower surface of the bottom cover 12.

[0031] The bottom cover 12 includes a convex base 126 for mounting the condensate absorbing cotton 6. After installation, the upper surface of the condensate absorbing cotton 6 is pressed and fixed by the lower surface of the atomizing element bracket 3. The condensate absorbing cotton 6 is used to absorb condensed aerosol and water vapor. The side wall of the bottom cover 12 is provided with a groove 122 for mounting a sealing ring 121, which forms a tight fit with the inner surface of the assembly part 112 to form a seal, ensuring that the atomized liquid and condensed liquid do not leak. An air intake 127 is provided below the bottom cover 12. When negative pressure is generated at the suction nozzle by suction, the outside air enters the atomizing device, mixes with the aerosol generated after atomization, and is discharged from the atomizing device through the air passage 13 and the suction nozzle. By providing the air intake 127 below the bottom cover 12, the atomizing device can be made more compact and the air passage more rational. In an embodiment that does not pursue this effect, the air intake may be provided on the outer shell.

[0032] With the decrease of the atomized liquid, it is necessary to timely replenish the air in the liquid storage chamber, otherwise the negative pressure in the liquid storage chamber may become excessive, which may affect the fluid supply. In a more preferred embodiment of the present invention, the atomizing element bracket 3 is divided into two parts, as shown in Figures 5 to 7, and includes an upper bracket sealing structure 3a and a lower bracket 3b. Please refer to Figures 6 to 7 for the specific structures of the bracket sealing structure 3a and the bracket 3b.

[0033] 6 is a cross-sectional view of the atomizing element bracket 3, and FIG. 7 is a three-dimensional view of the atomizing element bracket 3. The bracket sealing structure 3a includes a sealing frame 3a1, which has an arc-shaped cross section protruding from the surface of the sealing structure 3a. After assembly, it fits tightly with the inner wall of the mounting part 112 to form a seal with the inner wall of the mounting part 112 to prevent the atomizing liquid from leaking. The sealing structure 3a is provided with an elastic sealing gasket 3a2 made of silica gel or rubber at the part that contacts the bracket 3b. The part has a liquid guide surface 3b1 that extends downwardly, which enlarges the atomizing liquid flow path and ensures sufficient liquid supply.

[0034] Due to the convex design of the bracket 3b, the aperture of the lower atomization chamber 3b3 is larger than the aperture of the top opening 31, i.e., the aperture of the air passage 13. The bracket 3b is provided with an inclined surface at the front and / or rear, which forms an aerosol flow path 3b5 between the opening 31 and the atomization chamber 3b3. In addition, the lower end of the aerosol flow path 3b5 is larger and the upper end is smaller. During inhalation, the flow in the air passage 13 accelerates, and the mouth of the air passage is subjected to a larger negative pressure due to the Venturi effect, so that more aerosol can enter the air passage 13 and the condensation of liquid is reduced. The aerosol flow path during inhalation is indicated by arrow A in FIG. 2b. The air flow path is indicated by arrow B in FIG. 2b.

[0035] More preferably, an air passage 3b4 is provided on the side wall of the bracket 3b. An upper opening 3b7 of the air passage 3b4 is covered by a sealing gasket 3a2, and a lower opening 3b6 is open so that air can be replenished into the liquid storage chamber in a timely manner when the amount of atomized liquid in the liquid storage chamber is low. More preferably, the air passage 3b4 is provided to have a return shape such as a loop or a labyrinth shape, and the loop structure can lengthen the air passage 3b4 and narrow the aperture of the air passage. Even if a small amount of atomized liquid leaks into the air passage from the opening 3b5, the viscosity of the atomized liquid prevents it from flowing out of the air passage, thereby avoiding leakage of the atomized liquid.

[0036] In summary, the atomizing device of the present invention has a shorter and wider flow path for the atomized liquid from the reservoir chamber to enter the atomizing element assembly, and the design of the atomizing element bracket in the particularly preferred embodiment makes it easier for the atomized liquid to reach the straightening cotton, and the air in the reservoir chamber can be replenished in a timely manner, so as to avoid the problem of insufficient liquid supply. The design of the seal and condensed water absorption cotton provided in the atomized liquid flow path can avoid the leakage of the atomized liquid. At the same time, the rational design of the air flow path can make the atomized aerosol thoroughly mix with the air, improving the effect during use.

[0037] The above-mentioned embodiments are illustrative of the principles and effects of the present invention, but do not limit the present invention. Those skilled in the art may modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. For example, in the above-mentioned embodiment, the liquid inlet 115 (see FIG. 2) for injecting the atomizing liquid is provided on the outer shell, but this does not constitute a patent limitation. The principle of the present invention is also applicable to a closed-type atomizing device and a disposable-type atomizing device, or an oil filling port provided at a different position from the embodiment of the present invention, and this change is a conventional choice in the field and does not require creative work. The atomizing device of the present invention is plugged into the battery rod, but this connection is not essential, and various conventional connection methods such as screws and snaps can also be adopted. The size ratio between the suction nozzle and the mounting part can also be changed, and these changes do not affect the technical effect of the present invention. The rivet connection between the crown spring terminal 5 and the bottom cover 12 can also be replaced with a screw connection. In this embodiment, air is exchanged between the atomizing device and the outside by suction through the suction nozzle. In some applications, air exchange can also be achieved by injecting air into the air intake or discharging air from the suction nozzle, which are considered equivalent to the principle of the present invention. Therefore, all equivalent modifications or alterations made by a person having common knowledge in the technical field to which the present invention pertains without departing from the spirit and technical idea revealed by the present invention still fall within the scope of the claims of the present invention.
