[0041] See Figure 1 、 Figure 2 and Figure 3 The atomizer 10 provided in one embodiment of the present invention can convert electrical energy into thermal energy, thereby atomizing an atomizing matrix within the atomizer 10 to form an aerosol that can be inhaled by the user. The atomizing matrix can be a liquid aerosol-generating matrix such as oil. The atomizer 10 includes a housing 20, an atomizing assembly 30, an electrical connector 40, a sealing member 50, an atomizing seat 60, and a sealing ring 70. The housing 20 is used to accommodate the atomizing assembly 30, the electrical connector 40, the sealing member 50, the atomizing seat 60, and the sealing ring 70.

[0042] In some embodiments, the housing 20 defines an independent inhalation channel 21 and a liquid storage chamber 22. The liquid storage chamber 22 is used to store the liquid atomized matrix. The end of the inhalation channel 21 forms a mouthpiece 21a. When a user inhales through the mouthpiece 21a, the aerosol generated by the atomization of the atomized matrix can pass through the interior of the inhalation channel 21 and reach the mouthpiece 21a for inhalation by the user.

[0043] In some embodiments, the atomization assembly 30 includes a sealing sleeve 31 and an atomization core 32. The sealing sleeve 31 can be made of silicone material. The atomization core 32 includes a base 32a and a heating element. The sealing sleeve 31 is used to be mounted on the base 32a. The sealing sleeve 31 can play the role of supporting the base 32a and ensuring airtightness. The base 32a can be made of a porous ceramic material, so that a large number of micropores are formed inside the atomization core 32 and have a certain porosity. Through the capillary action of the micropores, the atomization core 32 can absorb and cache the atomization matrix. The heating element can be made of metal or alloy material. The heating element can convert electrical energy into thermal energy. The base 32a has an atomization surface 32b. The heating element is arranged on the atomization surface 32b. The atomization matrix soaked in the heating element and the atomization matrix on the atomization surface 32b can absorb heat energy to atomize and form an aerosol.

[0044] See Figure 1 、 Figure 4 and Figure 5 In some embodiments, the electrical connector 40 can be made of metal and alloy materials with low resistivity, and the electrical connector 40 can be integrally formed, which can improve the processing efficiency and subsequent assembly efficiency of the electrical connector 40. The electrical connector 40 includes a penetration portion 41 and a covering portion 42. The penetration portion 41 can be a roughly cylindrical rod-shaped structure, and the covering portion 42 can be a roughly flat disc-shaped structure, so that the cross-sectional dimension of the penetration portion 41 can be smaller than the cross-sectional dimension of the covering portion 42, that is, the diameter of the penetration portion 41 is smaller than the diameter of the covering portion 42. One end of the penetration portion 41 is connected to the edge of the covering portion 42, and the other end of the penetration portion 41 is a free end. When the electrical connector 40 is penetrated into the atomizer seat 60, the free end of the electrical connector 40 abuts against the heating element to achieve an electrical connection between the two, so that the electrical connector 40 can supply power to the heating element. There are two electrical connectors 40, one of which is used as a positive electrode and the other is used as a negative electrode.

[0045] In some embodiments, the sealing member 50 can be made of a silicone material. The sealing member 50 is used to seal the liquid storage chamber 22 to prevent leakage of the atomized matrix in the liquid storage chamber 22. The sealing member 50 includes a sleeve portion 51 and a covering portion 52. The covering portion 52 is generally a flat plate structure, and the sleeve portion 51 is generally a cylindrical structure. The sleeve portion 51 is connected to the periphery of the covering portion 52 and is arranged around the covering portion 52. Obviously, the sleeve portion 51 and the covering portion 52 together form an open cavity. An air guide notch 51a is provided on the sleeve portion 51, and the air guide notch 51a is connected to the open cavity; a through hole 52a is provided on the covering portion 52, and the through hole 52a is also connected to the open cavity. The through hole 52a can be located at the center of the covering portion 52. Obviously, the air guide notch 51a and the through hole 52a are connected to each other through the open cavity.

[0046] See Figure 5 、 Figure 6 and Figure 7 In some embodiments, the atomizer seat 60 is an integrally formed structure, and the atomizer seat 60 can be integrally formed by injection molding. The atomizer seat 60 has a top surface 100, a bottom surface 200, and a side surface 300. The top surface 100 and the bottom surface 200 are spaced apart along the axial direction of the atomizer seat 60, and both can extend substantially perpendicular to the axial direction of the atomizer seat 60. The side surface 300 is arranged around the central axis of the atomizer seat 60. The top surface 100 is arranged at one end of the side surface 300, so that the side surface 300 is connected to the periphery of the top surface 100; the bottom surface 200 is arranged at the other end of the side surface 300, so that the side surface 300 is also connected to the periphery of the bottom surface 200.

[0047] The sleeve portion 51 of the sealing member 50 is sleeved on the side surface 300 of the atomizing seat 60. The sleeve portion 51 is pressed between the side surface 300 and the housing 20, so that the sealing member 50 forms a sealing effect on the liquid storage chamber 22, preventing the atomized matrix from leaking from the gap between the housing 20 and the atomizing seat 60. The covering portion 52 covers and presses against the top surface 100. The top surface 100 is provided with a lower liquid hole 110. The covering portion 52 may be provided with a connecting hole 52b. The two ends of the connecting hole 52b respectively connect the liquid storage chamber 22 and the lower liquid hole 110, ensuring that the atomized matrix in the liquid storage chamber 22 is input into the lower liquid hole 110 through the connecting hole 52b.

[0048] In the direction away from the top surface 100, the caliber of the lower liquid hole 110 can be gradually reduced. In layman's terms, the lower liquid hole 110 is made to have a tapered structure with a large top and a small bottom, ensuring that the atomized matrix enters the lower liquid hole 110 smoothly, that is, ensuring smooth liquid flow, and at the same time, the flow rate of the atomized matrix in the lower liquid hole 110 can be reasonably determined. The atomizing seat 60 also has a hole wall surface, which defines the boundary of the lower liquid hole 110, and the hole wall surface is connected to the top surface 100. A drainage groove 111 is formed in the hole wall surface. Obviously, the drainage groove 111 is interconnected with the lower liquid hole 110. When the atomized matrix flows in the lower liquid hole 110, the atomized matrix will also flow in the drainage groove 111 at the same time, thereby increasing the cross-section of the flow cavity where the atomized matrix is ​​located, and further improving the smoothness of the flow of the atomized matrix in the lower liquid hole 110.

[0049] See Figure 2 and Figure 6 A receiving chamber 410 is provided in the atomizer seat 60. The receiving chamber 410 and the lower liquid hole 110 are interconnected. The receiving chamber 410 has an open opening 411 on the side circumferential surface 300. The entire atomizer assembly 30 can be received into the receiving chamber 410 from the open opening 411, so that the atomizer assembly 30 is generally installed into the atomizer seat 60 in a direction perpendicular to the central axis of the atomizer seat 60. In layman's terms, the atomizer assembly 30 is installed in the front-to-back direction. The atomizer seat 60 includes a baffle 430, which extends along the axial direction of the atomizer seat 60 and can define a portion of the boundary of the receiving chamber 410. When the atomizer assembly 30 is received in the receiving chamber 410, the sealing sleeve 31 of the atomizer assembly 30 abuts against the baffle 430. The abutting effect of the baffle 430 can effectively position the entire atomizing assembly 30 , thereby improving the assembly accuracy and efficiency of the atomizing assembly 30 .

[0050] An atomizing chamber 420 is also defined within the atomizing seat 60. The atomizing chamber 420 can communicate with the accommodating chamber 410. When the atomizing assembly 30 is accommodated in the accommodating chamber 410, the space between the atomizing assembly 30 and the atomizing seat 60 forms the atomizing chamber 420. The atomizing surface 32b of the atomizing assembly 30 can define a portion of the boundary of the atomizing chamber 420. When the atomizing core 32 is in operation, the atomizing matrix in the liquid storage chamber 22 penetrates into the base 32a through the lower liquid hole 110. The atomizing matrix that has penetrated into the base 32a will further reach the atomizing surface 32b, where the heat from the heating element is atomized to form an aerosol.

[0051] In some atomizer devices, the atomizer seat 60 is connected to a base and a top cover in a separate manner. For this type of split connection method of the atomizer seat 60, the base is used to install the electrical connector 40, the lower liquid hole 110 is opened on the top cover, and the atomizer assembly 30 is installed on the base in a direction roughly parallel to the central axis of the entire atomizer seat 60. That is, the atomizer assembly 30 is installed in the vertical direction, and then the top cover is installed on the base so that the atomizer assembly 30 is located between the base and the top cover. This will result in the atomizer seat 60 being composed of at least two parts, the base and the top cover, which will inevitably involve assembly between the base and the top cover, thereby affecting the installation efficiency of the entire atomizer 10. At the same time, in order to ensure the sealing performance of the atomizer 10 for gas and liquid, more sealing components are required. The installation of the sealing components is also time-consuming and laborious, which will also affect the assembly efficiency. Moreover, due to the limitations of tolerances and assembly processes, some sealing components may not be able to form a good seal, thereby causing the atomized matrix in the liquid storage chamber 22 to leak into the atomizing chamber 420, and then causing the atomized matrix leaked into the atomizing chamber 420 to flow out of the entire atomizer 10 and form liquid leakage.

[0052] In some embodiments, the atomizer seat 60 adopts an integrally formed connection method, so that the entire atomizer seat 60 is composed of only one part, and the atomizer assembly 30 is installed in the front-to-back direction, which can reduce the bumps and obstructions caused by interference during the installation of the atomizer assembly 30, making the installation method simpler and improving the assembly efficiency of the atomizer 10. It can also avoid the assembly between multiple parts, thereby improving the assembly efficiency of the atomizer 10. In addition, the setting of redundant sealing components is also eliminated, and the assembly efficiency is improved by omitting the installation of redundant sealing components; at the same time, it prevents some sealing components from failing to form a good sealing effect due to tolerances and assembly processes, avoids the atomizer matrix in the liquid storage chamber 22 from leaking into the atomizer chamber 420, reduces the possibility of the atomizer matrix further leaking outside the atomizer 10, and improves the anti-leakage performance of the atomizer 10.

[0053] See Figure 3 、 Figure 7 and Figure 8 In some embodiments, a ventilation groove 330 is formed on the side surface 300, which connects the outside world with the liquid storage chamber 22. When the atomized matrix is ​​consumed and a new release space is generated in the liquid storage chamber 22 that is not filled with atomized matrix, the outside air will enter the liquid storage chamber 22 through the ventilation groove 330 to fill the release space, thereby preventing the air pressure in the liquid storage chamber 22 from being lower than the outside air pressure, resulting in a phenomenon of poor liquid discharge of the atomized matrix, and preventing the atomizer core 32 from drying out due to the atomized matrix consumption rate being higher than the supply rate.

[0054] The value range of the groove width A of the ventilation groove 330 can be 0.35mm to 0.5mm, and the specific value of the groove width A can be 0.35mm, 0.4mm or 0.5mm, etc. The value range of the groove depth B of the ventilation groove 330 can be 0.3mm to 0.5mm, and the specific value of the groove depth B can be 0.3mm, 0.4mm or 0.5mm, etc. By setting the groove width A and the groove depth B as above, the ventilation groove 330 does not hinder the flow of gas, but can hinder the flow of the atomized matrix, ensuring that the ventilation groove 330 has the function of ventilation and liquid resistance, reducing the possibility of the atomized matrix in the liquid storage chamber 22 leaking through the ventilation groove 330.

[0055] The ventilation groove 330 includes a plurality of mutually connected ventilation sub-grooves 331, and the plurality of ventilation sub-grooves 331 are arranged at intervals along the axial direction of the atomizing seat 60. The atomizing seat 60 also has a bottom wall 332 and two side walls 333, and the bottom wall 332 and the two side walls 333 jointly define the partial boundary of the ventilation sub-grooves 331. The two side walls 333 are respectively connected with the opposite ends of the bottom wall 332 and are arranged at intervals along the axial direction of the atomizing seat 60. Of course, the end of the side wall 333 is also interconnected with the side circumferential surface 300. Along the direction of the bottom wall 332 pointing to the side circumferential surface 300, the distance between the side wall 333 and the top surface 100 is reduced. It can also be understood that along the direction away from the central axis of the atomizing seat 60, the distance between the side wall 333 and the top surface 100 is gradually reduced. As a result, the side wall surface 333 forms an upward chamfer α in the axial direction of the atomizer seat 60. When the atomized matrix flows from top to bottom along the ventilation groove 330, the chamfer α can constitute a greater resistance to the flow of the atomized matrix, thereby increasing the resistance along the flow of the atomized matrix in the ventilation groove 330, reducing the probability of the atomized matrix entering the ventilation groove 330 and slowing down the flow speed of the atomized matrix in the ventilation groove 330, thereby reducing the leakage of the atomized matrix in the liquid storage chamber 22. On the one hand, this avoids the waste of the atomized matrix, and on the other hand, it prevents the atomized matrix leaking from the liquid storage chamber 22 from further leaking out of the entire atomizer 10 and causing liquid leakage.

[0056] See Figure 2 and Figure 3 The sealing ring 70 may be an O-ring. The sealing ring 70 and the sealing member 50 are spaced axially apart from each other along the atomizer seat 60, such that the sealing ring 70 is closer to the bottom surface 200 than the sealing member 50. The sealing ring 70 is sleeved on the atomizer seat 60 and pressed between the side surface 300 and the housing 20. The provision of the sealing ring 70 further ensures the sealing performance of the atomizer 10 for gas and liquid.

[0057] See Figure 5 、 Figure 9 and Figure 10In some embodiments, the bottom surface 200 of the atomizer seat 60 is provided with an air inlet hole 210, an air inlet groove 220, and a mounting hole 230. The mounting hole 230 is interconnected with the atomizing chamber 420. The penetration portion 41 of the electrical connector 40 is penetrated through the mounting hole 230 to electrically connect with the heating element of the atomizer core 32. The penetration portion 41 can have an interference fit with the mounting hole 230, so that the electrical connector 40 can be fixed to the atomizer seat 60 by riveting. The depth of the recess of the air inlet hole 210 is greater than the depth of the recess of the air inlet groove 220, and the air inlet hole 210 and the air inlet groove 220 are interconnected. The air inlet 210 is formed with a mounting opening 211 on the bottom surface 200. The entire mounting opening 211 and at most a portion of the air inlet groove 220 are covered by the covering portion 42 of the electrical connector 40. That is, the covering portion 42 can cover only the mounting opening 211 or the mounting opening 211 and a portion of the air inlet groove 220. When the covering portion 42 covers only the mounting opening 211, a portion of the air inlet 210 forms an air inlet gap between the atomizer seat 60 and the covering portion 42. When a user inhales, external air enters the air inlet 210 through this air inlet gap. When the covering portion 42 covers the mounting opening 211 and a portion of the air inlet groove 220, a portion of the air inlet 210 and the air inlet groove 220 together form an air inlet gap between the atomizer seat 60 and the covering portion 42. External air also enters the air inlet 210 through this air inlet gap. After the electrical connector 40 is installed, the surface of the cover portion 42 can be flush with the bottom surface 200. Given that there are two electrical connectors 40, there are two air inlet holes 210 and two air inlet grooves 220. The two air inlet holes 210 are symmetrically arranged relative to the central axis of the atomizer seat 60, and the two air inlet grooves 220 are also symmetrically arranged relative to the central axis of the atomizer seat 60.

[0058] See Figure 6 、 Figure 7 and Figure 8 In some embodiments, the side surface 300 includes a first side surface 310 and a second side surface 320, and the first side surface 310 and the second side surface 320 are spaced apart along the axial direction perpendicular to the atomizer seat 60, for example, the first side surface 310 and the second side surface 320 are spaced apart along the front-to-back direction. A first air guide hole 311 is provided on the first side surface 310, and the first air guide hole 311 is directly connected to the atomizer chamber 420. A guide groove 312 is provided on the first side surface 310, and the number of the guide grooves 312 is two, and both guide grooves 312 extend roughly in the left-right direction. One end of each of the two guide grooves 312 is connected to the first air guide hole 311, and the other end of each of the two guide grooves 312 is connected to a different air inlet 210, and the two guide grooves 312 are symmetrically arranged relative to the first air guide hole 311, that is, the two guide grooves 312 are symmetrically arranged relative to the connection point between the two.

[0059] The guide groove 312 includes a first guide section 312a and a second guide section 312b that are interconnected. The first guide section 312a is directly connected to the first air guide hole 311, that is, the first guide section 312a is connected to the atomizing chamber 420 through the first air guide hole 311, and the second guide section 312b is directly connected to the air inlet 210, and the highest position of the second guide section 312b is higher than the highest position of the first guide section 312a. For example, with the axial direction of the atomizing seat 60 as the reference direction, the second guide section 312b is further away from the bottom surface 200 relative to the first guide section 312a, so that the height at which the second guide section 312b is located is higher than the height at which the first guide section 312a is located. The first guide section 312a extends along a first direction, and the first direction can be a horizontal direction. The second guide section 312b extends along a second direction, and the second direction is arranged at an angle to the first direction, and the second direction can be a vertical direction perpendicular to the first direction.

[0060] A second air guide hole 321 is provided on the second side surface 320, and the second air guide hole 321 is interconnected with the atomizing chamber 420. When the seal 50 is installed on the atomizing seat 60, the air guide notch 51a on the seal 50 corresponds to the second air guide hole 321 and is interconnected. A third air guide hole 120 is provided on the top surface 100, and the third air guide hole 120 is interconnected with the second air guide hole 321. When the seal 50 is installed on the atomizing seat 60, the through hole 52a on the seal 50 corresponds to the third air guide hole 120 and is interconnected. The central axis of the third air guide hole 120 can coincide with the central axis of the atomizing seat 60, that is, the third air guide hole 120 is centered, and a portion of the housing 20 is inserted in the through hole 52a and the third air guide hole 120, so that the third air guide hole 120 is interconnected with the air inlet channel 21.

[0061] When a user draws air at the mouthpiece 21a, ambient air passes through the air inlet groove 220, the air inlet hole 210, the second air guide section 312b, the first air guide section 312a, the first air guide hole 311, the atomizing chamber 420, the air guide gap 51a, the second air guide hole 321, the third air guide hole 120, and the air inhalation channel 21 to reach the mouthpiece 21a. Therefore, the air inlet groove 220, the air inlet hole 210, the air guide groove 312, the first air guide hole 311, the atomizing chamber 420, the air guide gap 51a, the second air guide hole 321, the third air guide hole 120, and the air inhalation channel 21 together form an air flow channel for air circulation. Figure 3 、 Figure 4 、 Figure 5 and Figure 7 The dashed arrows indicate the flow path of the gas.

[0062] Typically, the aerosol remaining in the atomizing chamber 420 will form condensate after cooling, and the atomized matrix in the atomizing core 32 may also drip into the atomizing chamber 420. Therefore, a certain amount of condensate and atomized matrix will be stored in the atomizing chamber 420, and the condensate and atomized matrix together form leakage liquid. For a traditional atomizer 10, either the leakage liquid will leak out of the atomizer 10 along the air flow channel. Or an additional liquid absorption component is provided to absorb the leakage liquid, which increases the difficulty of assembling the atomizer 10 and makes the structure of the atomizer 10 too complicated.

[0063] The atomizer 10 of the above embodiment can achieve at least the following beneficial effects:

[0064] First, gas is fed into the atomizing chamber 420 through the air intake gap between the atomizing seat 60 and the electrical connector 40. Due to the adhesion and blocking effects of the electrical connector 40, leaked liquid from the atomizing chamber 420 flowing into the air intake hole 210 is unlikely to leak out of the atomizer 10 through this air intake gap, thereby improving the anti-leakage performance of the atomizer 10. Furthermore, the covering portion 42 of the electrical connector 40 covers the mounting opening 211 of the air intake hole 210. The obstruction of the covering portion 42 makes it difficult, or even impossible, for small amounts of leaked liquid to leak out of the atomizer 10 through the air intake gap, further ensuring the anti-leakage performance of the atomizer 10. Therefore, by fully utilizing the adhesion and blocking effects of the electrical connector 40 itself, leaked liquid can be prevented from flowing out of the atomizer 10, eliminating the need for additional liquid-absorbing components. This simplifies the structure of the atomizer 10 and improves its assembly efficiency.

[0065] Second, when the leaked liquid in the atomizing chamber 420 enters the first guide groove 312 through the first air guide hole 311, the height of the second guide section 312b is higher than the height of the first guide section 312a, making it difficult for the liquid level in the first guide section 312a to reach the connection between the second guide section 312b and the air inlet 210. This makes it difficult for the leaked liquid in the first guide section 312a to flow into the air inlet 210 through the second guide section 312b, further reducing the possibility of the leaked liquid leaking out of the atomizer 10 through the air inlet gap. The length of the first guide section 312a can be greater than the length of the second guide section 312b, so that the first guide section 312a has a larger volume than the second guide section 312b, thereby allowing the first guide section 312a to store more leaked liquid, preventing the leaked liquid from flowing into the air inlet 210 and leaking out of the atomizer 10. When the atomizer 10 is inverted so that the mouthpiece 21 a faces downward, the second guide section 312 b can also store the leaked liquid to a certain extent, thereby preventing the leaked liquid from flowing out of the mouthpiece 21 a and causing leakage.

[0066] Third, when the user inhales, the external gas enters the atomizer 10 from the first air guide hole 311 and carries the aerosol to flow into the inhalation channel 21 from the second air guide hole 321. In short, the gas enters from one side of the atomizer seat 60 to carry the aerosol and flows out from the other side of the atomizer seat 60. In this way, the pressure formed by the gas can be more concentrated, and the gas carries as much aerosol as possible to leave the atomizer chamber 420 to enter the inhalation channel 21 and be absorbed by the user. On the one hand, the aerosol concentration can be increased, so that the user can form a richer inhalation taste. On the other hand, the amount of aerosol remaining in the atomizer chamber 420 can be reduced as much as possible, preventing the formation of excessive condensate due to excessive residual aerosol in the atomizer chamber 420, thereby reducing the formation of leakage liquid from the source and fundamentally, and ultimately improving the anti-leakage performance of the atomizer 10.

[0067] See Figure 11 For the assembly of the atomizer 10, a new assembly method can be used, which mainly includes the following steps:

[0068] In the first step, the sealing sleeve 31 is placed on the atomizing core 32 so that the two together form the atomizing assembly 30 .

[0069] In the second step, an integrally formed atomizer seat 60 is formed by injection molding, and a receiving cavity 410 is opened on the side surface 300 of the atomizer seat 60, so that the receiving cavity 410 forms an open opening 411 on the side surface 300. Of course, the order of the first and second steps can be reversed.

[0070] In the third step, the atomizer assembly 30 is installed into the accommodating cavity 410 from the open opening 411 , that is, from the side where the side surface 300 is located.

[0071] In the fourth step, the electrical connector 40 is inserted into the atomizer seat 60 by riveting and abutted against the atomizer core 32 , so as to achieve electrical connection between the electrical connector 40 and the atomizer core 32 .

[0072] The fifth step is to install the sealing member 50 and the sealing ring 70 on the atomizing seat 60. Of course, the order of the fourth step and the fifth step can be reversed.

[0073] In the sixth step, the atomizer seat 60 equipped with the atomizer assembly 30 , the electrical connector 40 , the sealing sleeve 31 and the sealing member 50 is installed into the housing 20 .

[0074] Therefore, since the atomizer seat 60 is integrally formed, the atomizer assembly 30 can be installed into the accommodating chamber 410 from the open opening 411 on the side circumferential surface 300. On the one hand, this reduces the collisions and obstructions caused by interference during the installation of the atomizer assembly 30, making the installation method simpler and improving the assembly efficiency of the atomizer assembly 30 and the atomizer 10. On the other hand, it reduces the number of parts constituting the atomizer seat 60 and the sealing components used between the various parts, thereby reducing the installation of redundant parts and sealing components, further improving the assembly efficiency of the atomizer 10. On the other hand, it can prevent the sealing components from failing to form a good sealing effect due to tolerances and assembly processes, reduce the leakage generated in the atomizer chamber 420, and improve the anti-leakage performance of the atomizer 10.

[0075] The present invention also provides an electronic atomization device comprising an atomizer 10 and a power supply, which supplies power to an atomizer core 32 via an electrical connector 40. The atomizer 10 exhibits excellent leak-proof properties, effectively preventing leaked liquid from entering the power supply and potentially corroding it, thereby increasing the power supply's service life and safety. Furthermore, the atomizer 10 exhibits high assembly efficiency, thereby increasing the assembly efficiency of the electronic atomization device and reducing its manufacturing cost.
