Description

Technical Field

[0001] The present invention relates to the field of aerosol matrix atomization, and in particular to an electronic atomization device for atomizing a liquid matrix. Background Art

[0002] Currently, a typical electronic atomization device on the market uses a ceramic heater to heat the liquid matrix. The ceramic heater uses its own porous properties to absorb the liquid matrix and heat it to atomize it to generate an aerosol. However, the ability of a single ceramic heater to absorb liquid and the working power are limited. The total particulate matter (TPM) of the generated aerosol often cannot meet the demand. Therefore, designing two or more ceramic heaters has become a trend.

[0003] In the prior art, the electrical conduction structure of a ceramic heater usually uses an electrode terminal to conduct power between the power source and one of the electrodes of the ceramic heater. If this structure is used when designing a dual ceramic heater, the two ceramic heaters need to be connected to four electrode terminals, which places relatively large requirements on the product structure space and is difficult to achieve within the limited structure space of the electronic atomization device. At the same time, the four electrode terminals also greatly increase the material cost and increase the complexity of assembly. Summary of the invention

[0055] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0056] like Figure 1 As shown, in this embodiment, an electronic atomization device 1 is provided, which can be used to atomize a liquid matrix into an aerosol. The electronic atomization device 1 includes an atomizer 12 and a power supply assembly 11 which are connected to each other.

[0057] The atomizer 12 is used to store the liquid matrix to be used and atomize the liquid matrix to form an aerosol for users to inhale. The liquid matrix can be a liquid medicine, a liquid of plant leaves, or a liquid matrix containing fruit extracts, etc. The atomizer 12 can be used in different fields, such as medical treatment, beauty, electronic aerosol atomization, etc. In some embodiments, the liquid matrix includes a solution containing nicotine salts. As an optional example, the liquid matrix also includes at least one of propylene glycol, glycerol, benzoic acid, and flavoring essences.

[0058] The power supply assembly 11 includes a battery cell (not shown), an airflow sensor (not shown), and a controller (not shown), etc.; the power supply assembly 11 is used to supply power to the atomizer 12 and control the operation of the atomizer 12, so that the atomizer 12 can atomize the liquid matrix to form an aerosol; the airflow sensor is used to detect airflow changes in the electronic atomization device 1, and the controller starts the electronic atomization device 1 according to the airflow changes detected by the airflow sensor.

[0059] The atomizer 12 and the power supply assembly 11 can be integrated or detachably connected, and can be designed according to specific needs. Of course, the electronic atomization device 1 also includes other components in the existing electronic atomization device 1. The specific structures and functions of these components are the same or similar to those in the prior art. For details, please refer to the prior art and will not be repeated here.

[0060] like Figures 2 to 3 As shown, the atomizer 12 includes a housing 2 , a bracket 4 , a base 5 , and a heating structure 3 .

[0061] The shell 2 has a first end 21 and a second end 22 which are opposite to each other in the longitudinal direction and an installation space between the first end 21 and the second end 22. The first end 21 is provided with a suction nozzle 23, and the second end 22 is provided with an opening 24. The bracket 4 is received in the installation space through the opening 24 and is fixedly connected to the inner side surface of the installation space through a first sealing ring 41. The side of the bracket 4 facing the first end 21 cooperates with the inner wall surface of a part of the installation space to form a liquid storage cavity for storing liquid matrix.

[0062] The nozzle 23 extends an air tube 25 toward the second end 22, the bracket 4 and the air tube 25 are butted against each other through a sealing silicone rubber 26, a vent hole 474 is provided at the butting position between the bracket 4 and the air tube 25, and the vent hole 474 and the air tube 25 form an air flow channel for aerosol to pass through. The bracket 4 has a mounting cavity on one side facing the second end 22, the heating structure 3 is accommodated in the mounting cavity, a buffer 42 is provided between the heating structure 3 and the bracket 4, the buffer 42 is made of silicone rubber or thermoplastic elastomer material, and the buffer 42 can also provide sealing in a partial area between the bracket 4 and the heating structure 3.

[0063] In some embodiments, a silicone plug 27 is sealed at the suction nozzle 23. The silicone plug 27 can prevent air from entering, thereby preventing the liquid matrix from deteriorating. The silicone plug 27 can be removed during use.

[0064] like Fig.13 and Fig.14 As shown, the bracket 4 in this embodiment includes a main body 47 and a bowl-shaped portion 48. The main body 47 has a receiving cavity 471 for accommodating the heating structure 3, and the main body 47 is provided with a liquid guide hole 46 for the liquid matrix to enter the receiving cavity 471; the bowl-shaped portion 48 surrounds the main body 47, and the bowl-shaped portion 48 has an inclined surface or an arc surface connected to the main body 47, and the lowest point of the inclined surface or the arc surface is connected to the liquid inlet 312, which is used to send the remaining liquid matrix to the liquid guide hole 46.

[0065] The bowl-shaped portion 48 of the bracket 4 cooperates with the inner wall surface of a part of the housing 2 to form a liquid storage cavity for storing liquid matrix.

[0066] Because the main body 47 is provided with a liquid guide hole 46 for the liquid matrix to enter the receiving cavity 471, the liquid matrix can enter the receiving cavity 471 accommodating the heating structure 3 through the liquid guide hole 46 in any direction. At the same time, because the bowl-shaped portion 48 surrounds the main body 47, the bowl-shaped portion 48 has an inclined surface or an arc surface connected to the main body 47, and the lowest point of the inclined surface or the arc surface is connected to the liquid inlet 472, which is used to deliver the remaining liquid matrix to the liquid guide hole 46, thereby ensuring that the liquid matrix is ​​transported to the heating structure 3 of the receiving cavity 471 through the liquid guide hole 46 to the greatest extent, ensuring that the amount of liquid matrix in the rear stage can be normally sucked even when the mass is relatively small, thereby greatly improving the utilization rate of the liquid matrix and the user experience.

[0067] like Fig.13 As shown, two grooves 472 are respectively disposed on two opposite sides of the main body 47 , and the liquid guide hole 46 is disposed in the groove 472 .

[0068] When a small amount of liquid matrix remains, the liquid guiding hole 46 is disposed in the groove 472 , so that the liquid guiding hole 46 is at the lowest point, and thus a small amount of liquid matrix can also enter the receiving cavity 471 through the liquid guiding hole 46 .

[0069] like Fig.13 As shown, the groove 73 is provided with a plurality of longitudinally extending bubble guide grooves 473 , and the bubble guide grooves 473 are communicated with the liquid guide hole 46 .

[0070] Since the liquid matrix will be consumed by the heating structure 3 after entering the receiving chamber 471 from the liquid guiding hole 46, a plurality of longitudinally extending bubble guiding grooves 473 are provided in the groove 472, and the bubble guiding grooves 473 are connected to the liquid guiding hole 46. Therefore, the bubbles generated by the liquid guiding hole 46 are guided to float upward by the bubble guiding grooves 473 without hindering the liquid matrix from entering the liquid guiding hole 46.

[0071] like Figure 7 and Figure 8 As shown, the heating structure 3 of this embodiment includes a heating component and an electrode component.

[0072] The heating assembly includes a first heating element 31 and a second heating element 32, wherein the first heating element 31 and the second heating element 32 are both used to heat the liquid matrix from the liquid storage chamber to generate an aerosol, the first heating element 31 has a first contact surface 311, and the second heating element 32 has a second contact surface 321 arranged opposite to the first contact surface 311;

[0073] The electrode assembly includes a first electrode 33 and a second electrode 34 that are spaced apart, at least a portion of the first electrode 33 and at least a portion of the second electrode 34 are clamped between the first heating element 31 and the second heating element 32, and the first electrode 33 is in contact with the first contact surface 311 and the second contact surface 321 at the same time, and the second electrode 34 is in contact with the first contact surface 311 and the second contact surface 321 at the same time, so that a gap is maintained between the first contact surface 311 and the second contact surface 321.

[0074] Since the first heating element 31 and the second heating element 32 are respectively provided with the first contact surface 311 and the second contact surface 321 which are parallel and opposite to each other, the first electrode 33 and the second electrode 34 are arranged at intervals with a gap between the first contact surface 311 and the second contact surface 321, the first electrode 33 contacts the first contact surface 311 and the second contact surface 321, and the second electrode 34 contacts the first contact surface 311 and the second contact surface 321, so that when the two electrodes are respectively connected to the positive and negative poles of the battery cell, the first heating element 31 and the second heating element 32 can be powered, so that the two heating elements can be electrically heated. Compared with the existing two heating ceramics which need to connect four electrodes to complete the electrical heating, the two heating elements of the present invention only need two electrodes to complete the electrical heating, thereby reducing the space occupied by the heating structure 3, and the assembly is also simpler, while reducing the material cost and production assembly cost of the electrode.

[0075] like Figure 7 As shown, the first electrode 33 and the second electrode 34 extend substantially parallel to the first contact surface 311 or the second contact surface 321 .

[0076] The first contact surface 311 and the second contact surface 321 serve as atomizing surfaces corresponding to the two heating elements, and the atomizing surfaces are longitudinally arranged parallel to the electrode direction, which is beneficial to reducing the lateral installation space in the atomizer 12; the gap between the atomizing surfaces of the two heating elements serves as an aerosol release space and provides airflow to pass through, effectively reducing the retention of aerosol.

[0077] In some embodiments, Figures 7 to 9 As shown, the first heating element 31 and the second heating element 32 may include a liquid-conducting substrate 313 made of a porous ceramic material and a heating unit 314 formed on the liquid-conducting substrate 313. The heating unit 314 may be a heating circuit formed on the surface of the liquid-conducting substrate 313 by printing or deposition of a resistor paste, or may be a heating sheet or heating net mounted and cured on the surface of the liquid-conducting substrate 313. In some examples, the liquid-conducting substrate 313 of the first heating element 31 or the second heating element 32 is configured in a flat plate shape. The first electrode 33 and the second electrode 34 are columns made of a conductive material, and the conductive material may be gold, silver, copper, or the like.

[0078] The first heating element 31 includes a first heating unit located on the first contact surface 311 , and the second heating element 32 includes a second heating unit located on the second contact surface 321 . The first heating unit and the second heating unit are connected in parallel between the first electrode 33 and the second electrode 34 .

[0079] like Figure 6 , Fig.11 , Fig.12As shown, the heating structure 3 of this embodiment also includes a sealing member 35 having a fixing groove 351 inside, the sealing member 35 has a top end and a bottom end opposite to each other in the longitudinal direction, the sealing member 35 is provided with a mounting opening at the top end, and the sealing member 35 is provided with an airway window 352 penetrating the fixing groove 351 at the bottom end, the first heating member 31 and the second heating member 32 can be installed in the fixing groove 351 at intervals through the mounting opening, the first electrode 33 and the second electrode 34 pass through the airway window 352 and partially extend into the fixing groove 351.

[0080] It should be noted that the sealing member 35 can be made of silicone material or thermoplastic elastomer.

[0081] The base 5 closes the opening 24 of the shell 2 and is provided with a fixing hole 51 and a fixing protrusion 52. The first electrode 33 and the second electrode 34 pass through the fixing hole 51. The seal 35 is provided with a fixing recess 45 at the bottom end. The fixing recess 45 and the fixing protrusion 52 are matched with each other.

[0082] like Figures 3 to 5 As shown, the base 5 is also provided with an air inlet 53, a first liquid injection hole 54, a first buckle 55 and a second buckle 56. When the user inhales into the nozzle 23, the gas enters the heating structure 3 through the air inlet 53. The bracket 4 is provided with a second liquid injection hole 44 at a position corresponding to the first liquid injection hole 54, the first liquid injection hole 54 and the second liquid injection hole 44 are connected to the liquid storage chamber, and the first liquid injection hole 54 is provided with a magnetic element 510, and the second liquid injection hole 44 is provided with a sealing plug 57, and the inner wall of the second liquid injection hole 44 is provided with a plurality of grooves, and an air replenishment channel is defined between the sealing plug 57 and the inner wall groove of the second liquid injection hole 44, and the position of the air replenishment channel is far away from the lower liquid channel of the ceramic heating element, so as to avoid the air channel gathering in the lower liquid channel to prevent the liquid from flowing to the ceramic heating element. The magnetic element 510 can be a ferromagnetic material, which is used to connect the atomizer 12 to the power supply assembly 11 through magnetic attraction, so as to maintain the conduction of the electrode.

[0083] The sealing plug 57 is used to prevent the liquid matrix from flowing out of the first injection hole 54 and the second injection hole 44. After the liquid matrix is ​​consumed, the user can open the sealing plug 57 and the magnetic element 510 to replenish the liquid matrix into the liquid storage cavity through the first injection hole 54 and the second injection hole 44. The bracket 4 is provided with a clamping groove 43 at a position corresponding to the first clamp 55, and the first clamp 55 is clamped with the clamping groove 43, so that the bracket 4 is firmly fixed in the installation cavity. The housing 2 is provided with a bayonet 28 at a position corresponding to the second clamp 56, and the second clamp 56 is clamped with the housing 2, so that the base 5 is fixed with the housing 2, and the outer periphery of the base 5 is sealed with the inner side of the housing 2 through the second sealing ring 58.

[0084] The assembly process of the heating structure 3 is as follows: first, the sealing member 35 is installed on the base 5, and the first electrode 33 and the second electrode 34 pre-assembled on the base 5 extend into the fixing groove 351 from the airway window 352 of the sealing member 35, and then the two first heating members 31 and the second heating members 32 are installed into the fixing groove 351 from the top of the fixing groove 351 and contact the first electrode 33 and the second electrode 34 in the middle, and finally, they are assembled with the bracket 4 together with the base 5.

[0085] Compared with the method of first installing the heating component into the sealing member 35 and then installing the electrode component, the advantage of the above-mentioned installation sequence of the heating structure 3 is that it can prevent the first electrode 33 and the second electrode 34 from hitting the bottom end surfaces of the first heating element 31 and the second heating element 32 when extending into the fixing groove 351, causing damage or displacement of the first heating element 31 and the second heating element 32.

[0086] like Fig.11 and Fig.12 As shown, in some embodiments, the sealing member 35 is provided with a separation rib 353 in the fixing groove 351 , and the separation rib 353 is located between the first heating member 31 and the second heating member 32 for separating the first heating member 31 from the second heating member 32 .

[0087] Two separation ribs 353 are provided, and are respectively located at the two lateral ends of the fixing groove 351. The two sides of the separation rib 353 are respectively in contact with the first heating element 31 and the second heating element 32, so as to separate the first heating element 31 from the second heating element 32. During the installation process of the first heating element 31 and the second heating element 32, the separation rib 353 can also play a guiding role, guiding the first heating element 31 and the second heating element 32 to be installed in the fixing groove 351, and fixing the positions of the first heating element 31 and the second heating element 32.

[0088] like Figure 8 As shown, the first electrode 33 and the second electrode 34 both include a first section 331 and a second section 332 sequentially connected along the longitudinal direction, the first section 331 contacts the heating component, and at least a portion of the second section 332 avoids the heating component.

[0089] The first electrode 33 and the first section 331 of the second electrode 34 are in contact with the heating assembly, thereby completing the connection between the electrode assembly and the heating assembly, and the battery cell supplies power to the heating assembly through the electrode assembly.

[0090] At least a portion of the second section 332 avoids the heating assembly, and when passing through the airway window 352, it may or may not collide with the inner wall of the airway window 352. Figure 5As shown, the inner wall of the airway window 352 can be provided with a plurality of protrusions 354, and the plurality of protrusions 354 are arranged in a ring at the edge of the airway window 352, and a plurality of capillary grooves 360 are formed between adjacent protrusions 354, and the capillary grooves 360 extend from the bottom wall of the fixed groove 351 to the bottom end of the seal 35, and the capillary grooves 360 extend toward both sides to form an arc, thereby guiding the liquid matrix from the infiltration in the above heating component or the condensation in the atomization chamber to the fiber absorption element 361 in the base 5, and the fiber absorption element 361 is used to retain a small amount of liquid matrix to prevent it from leaking to the outside of the electronic atomization device 1. As a suitable example, the fiber absorption element 361 includes fiber cotton. At the same time, when the first electrode 33 and the second electrode 34 extend into the fixed groove 351, the friction between the electrode assembly and the inner wall of the airway window 352 is reduced, and the first electrode 33 and the second electrode 34 are conveniently extended into the fixed groove 351.

[0091] Furthermore, if Figure 8 As shown, the diameter of the first section 331 is greater than the diameter of the second section 332 .

[0092] The diameter of the first section 331 is larger than the diameter of the second section 332, which can strengthen the electrical contact area between the first section 331 and the heating assembly, and maintain good contact between the electrode assembly and the heating assembly. Since the diameter of the second section 332 is smaller than the diameter of the first section 331, the downward conduction of heat can be reduced. At the same time, after the bracket 4 and the base 5 are installed, an atomization chamber is formed at the position of the fixing hole 51 and the vent, and the second section 332 is located in the atomization chamber, so the occupation of the atomization chamber space by the electrode assembly can be reduced, which is conducive to reducing the obstruction of the electrode assembly to the airflow.

[0093] Furthermore, if Figure 8 As shown, the first electrode 33 and the second electrode 34 further include a third section 333 connected to the second section 332 along the longitudinal direction. The third section 333 is fixed in the fixing hole 51 so that the electrode assembly can be fixedly mounted on the base 5 .

[0094] It is understandable that the diameter of the third section 333 may be greater than or equal to the diameter of the second section 332. Preferably, the diameter of the third section 333 is greater than the diameter of the second section 332, so that the third section 333 can better abut against the inner wall of the fixing hole 51, thereby strengthening the fixation of the electrode assembly and the base 5.

[0095] It should be noted that the first section 331 , the second section 332 and the third section 333 may be integrally formed of a conductive material.

[0096] Furthermore, if Figure 8As shown, the end of the third section 333 is laterally extended with a fourth section 334, and the fourth section 334 is laterally extended into a plate shape. By providing the plate-shaped fourth section 334, the connection area between the first electrode 33 (the second electrode 34) and the power supply is increased, and the connection between the power supply and the electrode assembly is facilitated.

[0097] Furthermore, the base 5 is provided with a receiving groove 59 on a side facing the second end 22 , and the receiving groove 59 is used to accommodate the fourth section 334 , thereby preventing the fourth section 334 from protruding from the bottom surface of the base 5 , thereby preventing the electrode assembly from being damaged.

[0098] like Figure 8 As shown, in some embodiments, the end of the first section 331 is configured to be tapered.

[0099] In the present embodiment, the electrode assembly and the heating assembly extend into the fixing groove 351 in opposite directions, and the electrode assembly contacts the heating assembly. Therefore, when the heating structure 3 is installed, in order to avoid the end of the electrode assembly extending into the fixing groove 351 from colliding with the end of the heating assembly extending into the fixing groove 351, causing damage or displacement of the electrode assembly and the heating assembly after installation, a cone is provided at the end of the first section 331 to avoid the end of the electrode assembly extending into the fixing groove 351 from colliding with the end of the heating assembly extending into the fixing groove 351.

[0100] Specifically, the heating structure 3 in this embodiment first extends the electrode assembly into the fixed groove 351, so that the end of the first section 331 is set to be conical, so that when the first heating element 31 and the second heating element 32 are installed in the fixed groove 351 and contact the conical surface, they will slide along the conical surface to the side of the first electrode 33 and the second electrode 34, thereby preventing the first heating element 31 and the second heating element 32 from pressing against the first electrode 33 and the second electrode 34.

[0101] like Figure 4 , Figure 5 , Fig.11 As shown, in this embodiment, the seal 35 includes a first portion 355 extending from the bottom end to the top end to form a vertical surface and a second portion 356 having two symmetrical inclined surfaces, and the two inclined surfaces of the second portion 356 are provided with liquid inlet holes 357 connected to the fixing groove 351.

[0102] The second portion 356 with the inclined surface can provide a guide to facilitate the installation of the seal 35 into the installation cavity of the bracket 4. The inner wall of the installation cavity of the bracket 4 also has a corresponding inclined surface, which matches the inclined surface on the second portion 356, ensuring the seal between the bracket 4 and the seal 35. At the same time, the bracket 4 is provided with a liquid guide hole 46 at a position corresponding to the liquid inlet perforation 357, and the liquid inlet perforation 357 is connected to the liquid storage cavity through the liquid guide hole 46.

[0103] like Fig. 9 and Fig.10 As shown, in this embodiment, the first heating element 31 is provided with a third contact surface 312 which is opposite to the first contact surface 311, and the second heating element 32 is provided with a fourth contact surface 322 which is opposite to the second contact surface 321; the third contact surface 312 and the fourth contact surface 322 are used to receive the liquid matrix from the liquid storage chamber through the liquid inlet hole 357.

[0104] The first heating element 31 and the second heating element 32 both include a liquid-conducting substrate 313 and a heating unit 314 combined with the liquid-conducting substrate 313, wherein the liquid-conducting substrate 313 has a micropore array area, wherein the micropore array area has a plurality of micropores extending in a directional manner, and is used to guide the liquid matrix from the third contact surface 312 to the first contact surface 311, and from the fourth contact surface 322 to the second contact surface 321; the micropore array area of ​​the first contact surface 311 and the second contact surface 321 is used as the atomizing area of ​​the atomizing surface, and the area outside the micropore array area in the atomizing surface is the non-atomizing area of ​​the atomizing surface, and the non-atomizing area is arranged around the atomizing area. The heating unit 314 is arranged in the atomizing area, and the electrode is connected to the heating unit 314. In this embodiment, the first heating element 31 and the second heating element 32 can also be a glass substrate, or a dense ceramic substrate.

[0105] In other embodiments, the first heating element 31 and the second heating element 32 both include a porous ceramic matrix and a heating unit 314, wherein the porous ceramic matrix of the first heating element 31 has a first contact surface 311 and a third contact surface 312 opposite to the first contact surface 311, and the heating unit 314 is combined on the first contact surface 311; the porous ceramic matrix of the second heating element 32 has a second contact surface 321 and a fourth contact surface 322 opposite to the second contact surface 321, and the heating unit 314 is combined on the second contact surface 321, and the two heating units 314 on the first contact surface 311 and the second contact surface 321 are connected to the power supply through the two electrodes of the electrode assembly.

[0106] like Fig.11 As shown, a first sealing rib 358 surrounding the first portion 355 is provided on the vertical surface, and a second sealing rib 359 surrounding the liquid inlet through hole 357 is provided on the inclined surface.

[0107] By providing a first sealing rib 358 and a second sealing rib 359 on the vertical surface of the first portion 355, the sealing between the sealing member 35 and the bracket 4 can be strengthened. Meanwhile, a second sealing rib 359 surrounding the liquid inlet through hole 357 is provided on the inclined surface of the second portion 356, thereby strengthening the sealing between the liquid inlet through hole 357 and the bracket 4, thereby preventing the liquid matrix from flowing into the air flow channel from the liquid inlet through hole 357.

[0108] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
