Referring to fig. 5, 6 and 7, in some embodiments, the atomizing base 60 is an integral structure, and the atomizing base 60 can be integrally formed by injection molding. The atomizing base 60 has a top surface 100, a bottom surface 200, and a side peripheral surface 300, and both the top surface 100 and the bottom surface 200 are spaced apart in the axial direction of the atomizing base 60, and both may extend substantially perpendicular to the axial direction of the atomizing base 60. The side circumference 300 is arranged around the central axis of the atomizing base 60, and the top surface 100 is arranged at one end of the side circumference 300, so that the side circumference 300 is connected with the periphery of the top surface 100; the bottom surface 200 is provided at the other end of the side circumferential surface 300, and also connects the side circumferential surface 300 with the periphery of the bottom surface 200.

The sleeve portion 51 of the sealing member 50 is sleeved on the side peripheral surface 300 of the atomizing base 60, and the sleeve portion 51 is pressed between the side peripheral surface 300 and the housing 20, so that the sealing member 50 forms a sealing function on the liquid storage cavity 22, and prevents the atomized matrix from leaking from a gap between the housing 20 and the atomizing base 60. The cover 52 covers and presses against the top surface 100. The top surface 100 is provided with a lower liquid hole 110, the covering part 52 is provided with a communication hole 52b, and two ends of the communication hole 52b are respectively communicated with the liquid storage cavity 22 and the lower liquid hole 110, so that the atomized matrix in the liquid storage cavity 22 can be ensured to be input into the lower liquid hole 110 through the communication hole 52 b.

Along the direction of keeping away from top surface 100, the bore of lower liquid hole 110 can reduce gradually, and colloquially says for lower liquid hole 110 is big end down's toper structure for it is smooth to guarantee to atomize the matrix and get into lower liquid hole 110 smoothly, guarantees to descend the liquid smoothly, can rationally confirm the flow of atomizing matrix in lower liquid hole 110 simultaneously. The atomizing base 60 also has a bore wall surface that defines the boundary of the downcomer bore 110, which is connected to the top surface 100. Obviously, the drainage grooves 111 are communicated with the lower liquid hole 110, when the atomized matrix flows in the lower liquid hole 110, the atomized matrix flows in the drainage grooves 111 at the same time, so that the cross section of the flow cavity where the atomized matrix is located is increased, and the smoothness of the flow of the atomized matrix in the lower liquid hole 110 is further improved.

Referring to fig. 2 and fig. 6, the atomizing base 60 has a receiving cavity 410 therein, the receiving cavity 410 is communicated with the lower liquid hole 110, an opening 411 is formed on a side surface 300 of the receiving cavity 410, and the whole atomizing assembly 30 can be received in the receiving cavity 410 through the opening 411, such that the atomizing assembly 30 is substantially loaded into the atomizing base 60 along a direction perpendicular to a central axis of the atomizing base 60, and in general, the atomizing assembly 30 is loaded along a front-back direction. The atomizing base 60 includes a baffle 430, the baffle 430 extends along an axial direction of the atomizing base 60, and the baffle 430 may define a partial boundary of the accommodating cavity 410, and when the atomizing assembly 30 is accommodated in the accommodating cavity 410, the sealing sleeve 31 of the atomizing assembly 30 abuts against the baffle 430. Due to the abutting effect of the baffle plate 430, the installation of the whole atomization assembly 30 can be well positioned, and the assembly precision and the assembly efficiency of the atomization assembly 30 can be improved.

The atomizing base 60 is further provided with an atomizing cavity 420 therein, the atomizing cavity 420 can be communicated with the accommodating cavity 410, when the atomizing assembly 30 is accommodated in the accommodating cavity 410, a part of space between the atomizing assembly 30 and the atomizing base 60 forms the atomizing cavity 420, and the atomizing surface 32b of the atomizing assembly 30 can define a part of the boundary of the atomizing cavity 420. When atomizing core 32 works, the atomizing substrate in liquid storage cavity 22 permeates into base 32a through lower liquid hole 110, the atomizing substrate permeating into base 32a further reaches atomizing surface 32b, and the heat of the heating element is atomized to form aerosol.

In some atomizing devices, the atomizing base 60 is a base and a top cover which are separately connected, in this way, the base is used for installing the electric connecting piece 40, the liquid outlet 110 is arranged on the top cover, the atomizing assembly 30 is loaded onto the base along a direction approximately parallel to the central axis of the whole atomizing base 60, that is, the atomizing assembly 30 is loaded along the up-down direction, and then the top cover is installed on the base, so that the atomizing assembly 30 is located between the base and the top cover. This results in the atomizer base 60 being formed of at least two parts, namely a base and a cover, which necessarily involves assembly between the base and the cover, thereby affecting the efficiency of installation of the entire atomizer 10. Simultaneously, for guaranteeing the leakproofness of atomizer 10 to gas and liquid, need use more seal part, seal part's installation is equally time-consuming and arduous, also can influence assembly efficiency, and, because tolerance and assembly process's limitation, also can make some seal part can't form fine sealing, thereby lead to the atomizing matrix in the stock solution chamber 22 to leak to atomizing chamber 420 in, and then make the atomizing matrix that leaks to in the atomizing chamber 420 flow outside whole atomizer 10 and form the weeping.

In some embodiments, the atomizing base 60 is integrally formed, so that the whole atomizing base 60 is formed by only one part, and the atomizing assembly 30 is installed in the front-rear direction, which can reduce the collision and obstruction of the atomizing assembly 30 caused by interference in the installation process, so that the installation method is simpler, and the assembly efficiency of the atomizer 10 is improved. Assembly between multiple parts can also be avoided, thereby improving the efficiency of assembly of the atomizer 10. In addition, the arrangement of redundant sealing components is omitted, and the assembly efficiency is improved by omitting the installation of the redundant sealing components; meanwhile, the sealing effect of the parts of the sealing parts cannot be well formed due to the influence of tolerance and assembly process is prevented, the atomized matrix in the liquid storage cavity 22 is prevented from leaking into the atomizing cavity 420, the possibility that the atomized matrix further leaks out of the atomizer 10 is reduced, and the leakage-proof performance of the atomizer 10 is improved.

Referring to fig. 3, 7 and 8, in some embodiments, the side surface 300 is formed with a ventilation slot 330, and the ventilation slot 330 communicates with the outside and the liquid storage chamber 22. When a new release space which is not filled with the atomized matrix is generated in the liquid storage cavity 22 due to the consumption of the atomized matrix, the external gas enters the liquid storage cavity 22 through the ventilation slot 330 to fill the release space, so that the phenomenon of unsmooth liquid discharge of the atomized matrix due to the fact that the air pressure in the liquid storage cavity 22 is smaller than the external air pressure is avoided, and dry burning of the atomization core 32 due to the fact that the consumption speed of the atomized matrix is higher than the supply speed is prevented.

The value of the groove width a of the ventilation groove 330 may range from 0.35mm to 0.5mm, and the specific value of the groove width a may be 0.35mm, 0.4mm, or 0.5mm, etc. The groove depth B of the ventilation groove 330 may range from 0.3mm to 0.5mm, and the specific value of the groove depth B may be 0.3mm, 0.4mm, or 0.5 mm. By providing the groove width a and the groove depth B as described above, the ventilation groove 330 can prevent the flow of the gas, but can prevent the flow of the aerosol substrate, thereby ensuring that the ventilation groove 330 has the function of ventilation and liquid blocking, and reducing the possibility of the aerosol substrate in the reservoir chamber 22 leaking through the ventilation groove 330.

The ventilation groove 330 includes a plurality of ventilation sub-grooves 331 communicating with each other, and the plurality of ventilation sub-grooves 331 are arranged at intervals in the axial direction of the atomizing base 60. The atomizing base 60 also has a bottom wall surface 332 and two side wall surfaces 333, and the bottom wall surface 332 and the two side wall surfaces 333 together define part of the boundary of the scavenging sub-groove 331. The two side wall surfaces 333 are connected to the opposite ends of the bottom wall surface 332, respectively, and are provided at intervals in the axial direction of the atomizing base 60, and of course, the end portions of the side wall surfaces 333 are also connected to the side circumferential surface 300. The distance from the side wall surface 333 to the top surface 100 decreases in the direction in which the bottom wall surface 332 is directed toward the side circumferential surface 300. It is also understood that the distance from the sidewall surface 333 to the top surface 100 decreases in a direction away from the central axis of the atomizing base 60. Thereby, the sidewall surface 333 forms an upward chamfer α in the axial direction of the aerosol base 60, and the chamfer α may provide a greater resistance to the flow of the aerosol base material during the process of flowing the aerosol base material along the air vent 330 from top to bottom, thereby increasing the on-way resistance of the aerosol base material flowing in the air vent 330, decreasing the probability of the aerosol base material entering the air vent 330, and decreasing the flow rate of the aerosol base material in the air vent 330, thereby decreasing the leakage of the aerosol base material in the reservoir 22. On the one hand, the waste of the nebulized matrix is avoided and, on the other hand, the leakage of nebulized matrix from the reservoir 22 further out of the entire nebulizer 10 to form a leakage is avoided.

Referring to fig. 2 and 3, seal ring 70 may be an O-ring 70, with seal ring 70 and seal 50 spaced axially along atomizing base 60 such that seal ring 70 is closer to bottom surface 200 than seal 50. The sealing ring 70 is sleeved on the atomizing base 60 and pressed between the side surface 300 and the housing 20, and by providing the sealing ring 70, the sealing performance of the atomizer 10 against gas and liquid can be further ensured.

Referring to fig. 5, 9 and 10, in some embodiments, the bottom surface 200 of the atomizing base 60 is provided with an air inlet 210, an air inlet slot 220 and a mounting hole 230, the mounting hole 230 is communicated with the atomizing chamber 420, a penetrating portion 41 of the electrical connector 40 is penetrated in the mounting hole 230 so as to be electrically connected with the heating element of the atomizing core 32, and the penetrating portion 41 can be in interference fit with the mounting hole 230, so that the electrical connector 40 can be fixed on the atomizing base 60 by riveting. The depth of the depression of the intake hole 210 is greater than the depth of the depression of the intake groove 220, and the intake hole 210 and the intake groove 220 are communicated with each other. The air intake holes 210 are formed with mounting openings 211 on the bottom surface 200, and the entire mounting openings 211 and at most a part of the air intake grooves 220 are covered with the covering portions 42 of the electric connection members 40, that is, the covering portions 42 may cover only the mounting openings 211 and may also cover the mounting openings 211 and a part of the air intake grooves 220. When the cover portion 42 covers only the mounting opening 211, a portion of the air intake hole 210 forms an air intake gap between the atomizing base 60 and the cover portion 42, through which the external air enters into the air intake hole 210 when the user sucks. When the cover portion 42 covers the mounting opening 211 and a part of the air inlet groove 220, a part of the air inlet hole 210 and a part of the air inlet groove 220 together form an air inlet gap between the atomizing base 60 and the cover portion 42, and the outside air also enters the air inlet hole 210 through the air inlet gap. The surface of cover portion 42 may be flush with bottom surface 200 after electrical connector 40 is installed. Considering that the number of the electrical connectors 40 is two, the number of the air inlet holes 210 and the number of the air inlet slots 220 are two, the two air inlet holes 210 are symmetrically arranged relative to the central axis of the atomizing base 60, and the two air inlet slots 220 are also symmetrically arranged relative to the central axis of the atomizing base 60.

Referring to fig. 6, 7, and 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 from each other in an axial direction perpendicular to the atomizing base 60, for example, the first side surface 310 and the second side surface 320 are spaced apart from each other in a front-rear direction. First air-guide hole 311 has been seted up on first side 310, and first air-guide hole 311 directly communicates with atomizing chamber 420, and guiding gutter 312 has been seted up to first side 310, and the quantity of guiding gutter 312 is two, and two guiding gutters 312 all extend along left right direction roughly. One end of each of the two guiding grooves 312 is communicated with the first air vent 311, the other end of each of the two guiding grooves 312 is communicated with a different air inlet 210, and the two guiding grooves 312 are symmetrically arranged relative to the first air vent 311, that is, the two guiding grooves 312 are symmetrically arranged relative to the communication position of the two guiding grooves 312.

The guiding groove 312 includes a first guiding section 312a and a second guiding section 312b which are communicated with each other, the first guiding section 312a is directly communicated with the first air guide hole 311, that is, the first guiding section 312a is communicated with the atomizing cavity 420 through the first air guide hole 311, the second guiding section 312b is directly communicated with the air inlet hole 210, and the highest position of the second guiding section 312b is higher than that of the first guiding section 312 a. For example, with the axial direction of the atomizing base 60 as a reference direction, the second flow guiding section 312b is farther away from the bottom surface 200 relative to the first flow guiding section 312a, so that the second flow guiding section 312b is located at a higher height than the first flow guiding section 312 a. The first flow guiding section 312a extends along a first direction, which may be a horizontal direction, and the second flow guiding section 312b extends along a second direction, which forms an included angle with the first direction, and which may be a vertical direction perpendicular to the first direction.

The second side surface 320 is provided with a second air hole 321, the second air hole 321 is communicated with the atomizing chamber 420, and when the sealing member 50 is mounted on the atomizing base 60, the air guide notch 51a of the sealing member 50 is communicated with the second air hole 321 correspondingly. The top surface 100 is opened with a third air hole 120, the third air hole 120 is communicated with the second air hole 321, and when the sealing element 50 is mounted on the atomizing base 60, the through hole 52a of the sealing element 50 is communicated with the third air hole 120 correspondingly. The central axis of the third air-guide hole 120 may coincide with the central axis of the atomizing base 60, that is, the third air-guide hole 120 is centrally disposed, and a portion of the housing 20 is inserted into the through-hole 52a and the third air-guide hole 120, so that the third air-guide hole 120 and the suction passage 21 communicate with each other.

When a user sucks at the nozzle opening 21a, the external air sequentially passes through the air inlet slot 220, the air inlet hole 210, the second flow guiding section 312b, the first flow guiding section 312a, the first air guide hole 311, the atomizing chamber 420, the air guide notch 51a, the second air guide hole 321, the third air guide hole 120 and the air suction channel 21 to reach the nozzle opening 21 a. Therefore, the air inlet slot 220, the air inlet hole 210, the guiding slot 312, the first air guide hole 311, the atomizing cavity 420, the air guide notch 51a, the second air guide hole 321, the third air guide hole 120 and the air suction channel 21 together form an air flow channel for air circulation. The flow path of the gas is indicated by the dashed arrows in fig. 3, 4, 5 and 7.

Typically, the aerosol remaining in the aerosolizing chamber 420 will form a condensate upon cooling, and the aerosolizing substrate in the aerosolizing wick 32 may also drip into the aerosolizing chamber 420, and thus, the aerosolizing chamber 420 will store some condensate and aerosolizing substrate that together form a spill. With conventional atomizers 10, either the leakage liquid will leak out of the atomizer 10 along the airflow path. Or an additional liquid absorbing component is arranged to absorb the leaked liquid, which increases the assembly difficulty of the atomizer 10 and also makes the structure of the atomizer 10 too complicated.

With the atomizer 10 of the above embodiment, at least the following advantageous effects can be achieved:

first, gas is input into the atomizing chamber 420 through the air inlet gap between the atomizing base 60 and the electrical connecting member 40, so that leakage liquid flowing into the air inlet hole 210 from the atomizing chamber 420 is difficult to leak out of the atomizer 10 through the air inlet gap under the adhering and blocking effects of the electrical connecting member 40, thereby improving the leakage prevention performance of the atomizer 10. Further, the covering portion 42 of the electrical connector 40 covers the mounting opening 211 of the air intake hole 210, and a small amount of leakage liquid flowing out of the air intake hole 210 is difficult to leak out of the atomizer 10 even from the air intake gap due to the blocking effect of the covering portion 42, so that the leakage-proof performance of the atomizer 10 is further ensured. Therefore, the adhesion and blocking effects of the electrical connector 40 itself are fully utilized to prevent leakage liquid from flowing out of the atomizer 10, and no other liquid suction member is required, thereby simplifying the structure of the atomizer 10 and improving the assembly efficiency of the atomizer 10.

Secondly, when the leakage liquid in the atomizing cavity 420 enters the first guiding groove 312 through the first air guiding hole 311, the height of the second guiding section 312b is higher than the height of the first guiding section 312a, so that the liquid level in the first guiding section 312a is difficult to reach the connection between the second guiding section 312b and the air inlet hole 210, and then the leakage liquid in the first guiding section 312a is difficult to flow into the air inlet hole 210 through the second guiding section 312b, thereby further reducing the possibility that the leakage liquid leaks out of the atomizer 10 from the air inlet gap. The length of the first flow guiding section 312a may be greater than that of the second flow guiding section 312b, so that the first flow guiding section 312a has a larger volume than the second flow guiding section 312b, and thus the first flow guiding section 312a can store more leakage liquid, and the leakage liquid is prevented from flowing into the air inlet hole 210 and leaking out of the atomizer 10. When the atomizer 10 is inverted so that the nozzle opening 21a faces downward, the second flow guiding section 312b may also play a role in storing leakage liquid to a certain extent, so as to prevent leakage liquid from flowing out of the nozzle opening 21a and causing leakage.

Thirdly, when a user sucks, the external air enters the atomizer 10 from the first air guide holes 311 to carry the aerosol to flow into the air suction channel 21 from the second air guide holes 321, in short, the air enters from one side of the atomizing base 60 to carry the aerosol to flow out from the other side of the atomizing base 60, so that the pressure formed by the air is more concentrated, the air carries more aerosol as far as possible to leave the atomizing cavity 420 to enter the air suction channel 21 to be absorbed by the user, and on one hand, the suction concentration of the aerosol can be increased, so that the user forms a stronger suction taste. On the other hand, the amount of aerosol remaining in the atomizing chamber 420 can be reduced as much as possible, and excessive condensate formed in the atomizing chamber 420 due to the remaining excessive aerosol is prevented, so that the formation of leakage liquid is fundamentally reduced from the source, and the leakage prevention performance of the atomizer 10 is finally improved.

Referring to fig. 11, for the assembly of the atomizer 10, a completely new assembly method can be adopted, which mainly comprises the following steps:

in the first step, the sealing sleeve 31 is sleeved on the atomizing core 32, so that the two forms the atomizing assembly 30.

Secondly, the atomizing base 60 is formed by injection molding, and the receiving cavity 410 is opened on the side surface 300 of the atomizing base 60, so that the receiving cavity 410 forms an opening 411 on the side surface 300. Of course, the order of the first and second steps may be reversed.

In the third step, the atomizing assembly 30 is loaded into the accommodating chamber 410 from the opening 411, that is, from the side where the side circumferential surface 300 is located, into the accommodating chamber 410.

Fourthly, the electric connecting piece 40 is arranged in the atomizing base 60 in a riveting and pressing mode and is abutted with the atomizing core 32, so that the electric connecting piece 40 is electrically connected with the atomizing core 32.

In the fifth step, the sealing member 50 and the sealing ring 70 are mounted on the atomizing base 60. Of course, the order of the fourth step and the fifth step may be reversed.

Sixth, the atomizing base 60, with the atomizing assembly 30, the electrical connector 40, the sealing sleeve 31 and the sealing member 50 installed, is installed into the housing 20.

Therefore, because the atomizing base 60 is integrally formed, the atomizing assembly 30 can be loaded into the accommodating cavity 410 from the opening 411 on the side circumferential surface 300, on one hand, the collision and obstruction caused by interference in the installation process of the atomizing assembly 30 are reduced, the installation mode is simpler, and the assembly efficiency of the atomizing assembly 30 and the atomizer 10 is improved. On the other hand, the number of parts forming the atomizing base 60 is reduced, and the sealing parts used among the parts are also reduced, so that the installation of redundant parts and sealing parts is reduced, and the assembly efficiency of the atomizer 10 is further improved. On the other hand, the sealing member can be prevented from failing to form a good sealing effect due to the influence of tolerance and assembly process, leakage liquid generated in the atomizing chamber 420 is reduced, and the leakage-proof performance of the atomizer 10 is improved.

The utility model also provides an electronic atomization device, this electronic atomization device include atomizer 10 and power, and the power passes through electric connector 40 and supplies power to atomizing core 32. Because the atomizer 10 has good leakage-proof performance, leakage liquid can be effectively prevented from entering the power supply to corrode the power supply, and the service life and the use safety of the power supply are improved. Meanwhile, the atomizer 10 has high assembly efficiency, and the assembly efficiency of the electronic atomization device can be improved, so that the manufacturing cost of the electronic atomization device is reduced.
