Description

Technical Field

[0001] The present invention relates to the field of aerosol supply, and particularly to an aerosol supply system. Background Art

[0002] An aerosol supply system refers to a system that internally accommodates aerosol generating materials and generates aerosol by heating rather than burning the aerosol generating materials (such as tobacco) for users to inhale.

[0003] An aerosol supply system generally includes a housing, an atomizer disposed in the housing, a power source, and a controller. The atomizer includes a heating element. The power source supplies power to the heating element under the control of the controller. The heating element is energized to generate heat to heat the aerosol generating materials in the housing, thereby generating aerosol.

[0004] The atomizer includes an atomizer bracket that defines an atomization chamber and a heating element disposed in the atomization chamber. During system assembly, the lead pins of the heating element are led out to be electrically connected to the electrodes outside the atomization chamber, and the electrodes are electrically connected to the power source to achieve power supply from the power source to the heating element. Currently, the connection between the lead pins of the heating element and the electrodes is carried out by welding. However, welding itself is a complex process, resulting in a complex system assembly process; at the same time, welding requires leading the pins out of the atomization chamber, and the required length of the pins is relatively long. To achieve stable welding, certain dimensional requirements are imposed on both the pins and the electrodes, which results in a relatively large overall volume of the system.

[0005] Therefore, there is an urgent need for a new aerosol supply system to solve one or more of the technical problems existing in the above aerosol supply system. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention discloses an aerosol supply system to solve the problems such as complex assembly and large system volume caused by welding between the lead pins of the heating element and the electrodes in the prior art.

[0007] The present invention discloses an aerosol supply system, the system comprising:

[0008] A proximal end and a distal end facing away from each other in the height direction;

[0009] A mouthpiece located at the proximal end;

[0010] A heating element having lead pins;

[0011] An atomizer bracket provided with a limiting hole, the atomizer bracket defining a chamber for accommodating the heating element, and a first opening is formed in the limiting hole;

[0012] An electrode extending into the limiting hole from the first opening and contacting the lead pins in the limiting hole;

[0013] There is a solderless connection between the pin and the electrode.

[0014] In an embodiment of the present invention, a solderless connection is achieved by providing a limiting hole. This solderless connection can specifically be pressure abutment, snap connection, magnetic connection, adhesive connection, elastic interference fit, etc. Compared with the prior art, these connection methods all eliminate the soldering process and simplify the complexity of assembly; and there is no need to make large-size preparations for soldering, so the volume of the system can be correspondingly reduced in design.

[0015] In an embodiment of the above aerosol supply system, the atomizer bracket is further provided with a through hole communicating with the limiting hole. There is an included angle between the axis of the through hole and the axis of the limiting hole. The through hole has a second opening facing away from the limiting hole. The pin is inserted into the through hole from the second opening and at least partially extends into the limiting hole through the through hole. Further, the pin and the electrode are configured to enter the limiting hole from different openings, which improves the flexibility of the position setting of the pin and the electrode, and facilitates the pin and the electrode to enter the limiting hole through their respective closer openings relative to the atomizer bracket, reducing the sizes of the pin and the electrode.

[0016] In an embodiment of the above aerosol supply system, the limiting hole extends along the height direction and has the first opening on the side facing the distal end.

[0017] In an embodiment of the above aerosol supply system, the pin has a first portion extending into and located within the through hole and a second portion extending into and located within the limiting hole. There is a bending angle between the first portion and the second portion.

[0018] In an embodiment of the above aerosol supply system, the side surface of the electrode contacts the side surface of the second portion.

[0019] In an embodiment of the above aerosol supply system, the portion of the electrode inserted into the limiting hole is parallel to the second portion.

[0020] In an embodiment of the above aerosol supply system, in the cross-sectional direction of the limiting hole, the pin has a lateral length that can be exposed within the hole passage of the limiting hole;

[0021] During the process of the electrode extending into the limiting hole, the electrode abuts against the lateral length to bend the pin to form the second portion. Based on the setting of this embodiment, the electrode can abut against the pin while extending into the limiting hole to bend and form the second portion electrically connected to the electrode, without pre-bending the pin in advance, further simplifying the assembly process.

[0022] In one embodiment of the above aerosol supply system, the shapes of the two sides of the second part in contact with the electrode are adapted to each other. For example, adapted concave-convex surfaces, adapted arc surfaces, adapted flat surfaces, etc. By adapting the shapes of the two sides, the contact area between the pin and the electrode can be increased, the tightness of the connection between the pin and the electrode can be improved, and thus the stability of the electrical connection can be improved.

[0023] In one embodiment of the above aerosol supply system, the bending angle of the first part and the second part has a maximum thickness and / or a maximum width. Based on the setting of this embodiment, the strength of the bending part can be improved, the probability of breakage at the bending part can be reduced, and the stability of the electrical connection can be improved.

[0024] In one embodiment of the above aerosol supply system, the pin has a first part extending into and located within the through hole and a second part extending into and located within the limiting hole, and the first part and the second part are located in the same plane.

[0025] In one embodiment of the above aerosol supply system, an end face of one of the second part and the electrode contacts a side face of the other.

[0026] In one embodiment of the above aerosol supply system, the part of the electrode inserted into the limiting hole is perpendicular to the second part. Based on the perpendicular setting of this embodiment, the contact area between the pin and the electrode can be increased, and thus the stability of the electrical connection can be improved.

[0027] In one embodiment of the above aerosol supply system, the end face of the second part contacts the side face of the electrode;

[0028] The end face of the second part is recessed to form an open ring, and the electrode is inserted into the open ring. Based on the open ring setting of this embodiment, the electrode ring is surrounded, the stability of the connection is improved, and at the same time, the contact area between the pin and the electrode is increased, and the stability of the electrical connection is improved as a whole.

[0029] In one embodiment of the above aerosol supply system, the opening size of the open ring is set to prevent the electrode from moving out of the opening. Based on this setting, the electrode is tightly ringed within the open ring, and the stability of the connection is improved.

[0030] In one embodiment of the above aerosol supply system, an elastic member is further included, configured to provide a force for the electrode and the pin to tend to approach each other. Based on the elastic member setting of this embodiment, there is a force for the electrode and the pin to tend to approach each other more, and the stability and tightness of the connection between the two are improved.

[0031] In an embodiment of the above aerosol supply system, first and second contact surfaces parallel to each other are formed among the electrode, the pin, and the inner wall of the limiting hole; wherein,

[0032] The electrode contacts the pin on one side surface to form a first contact surface, and contacts the inner wall on the opposite side surface to form a second contact surface, or the pin contacts the electrode on one side surface to form a first contact surface, and contacts the inner wall on the opposite side surface to form a second contact surface;

[0033] The elastic member is located on the first contact surface or the second contact surface.

[0034] In an embodiment of the above aerosol supply system, the elastic member is at least one of the following:

[0035] The elastic member is the limiting hole, and the inner wall surface of the limiting hole is an elastic surface;

[0036] The elastic member is the pin, and the side surface of the pin close to the inner wall surface of the limiting hole is an elastic surface;

[0037] The elastic member is the electrode, and the side surface of the electrode close to the inner wall surface of the limiting hole is an elastic surface.

[0038] In an embodiment of the above aerosol supply system, the elastic member is corrugated.

[0039] In an embodiment of the above aerosol supply system, the pressure between the pin and the electrode is in abutment, or they are elastically connected, or snap-connected, or magnetically connected, or adhesively connected.

[0040] In an embodiment of the above aerosol supply system, it further includes:

[0041] A housing;

[0042] A power source, the power source is arranged in the housing and is configured to supply power to the heating element through the electrode and the pin;

[0043] And the aerosol generating material accommodated in the system.

[0044] Based on the embodiments of the present invention, by providing a limiting hole in the atomizer bracket and limiting the pins of the heating element and the electrodes within the limiting hole, the limiting of the pins and the electrodes is achieved, and a solderless connection is realized based on the limiting effect of the limiting hole. This solderless connection can specifically be pressure abutment, snap connection, elastic interference fit, etc. Compared with the prior art, these connection methods all eliminate the soldering process and simplify the complexity of assembly; and since there is no need to prepare dimensions for soldering, the volume of the system can be correspondingly reduced in design. Further, through the provision of multiple openings and the provision of elastic members, the stability of the solderless connection is improved, and the volume of the system can be further reduced.

[0094] A consumable is an article that comprises or consists of an aerosol - forming material, at least part of which is intended to be consumed by a user during use. The consumable may include one or more other components, such as an aerosol - forming material storage area, an aerosol - forming material delivery component, an aerosol - forming area, a housing, a wrapper, a mouthpiece, a filter, and / or an aerosol modifier. The consumable may also include an aerosol generator, such as a heater, which releases heat during use to cause the aerosol - forming material to form an aerosol. The heater may, for example, comprise a combustible material, a material that can be heated by electrical conduction, or a susceptor.

[0095] A susceptor is a material that can be heated by penetration with a varying magnetic field (such as an alternating magnetic field). The susceptor may be a conductive material such that penetration by the varying magnetic field causes inductive heating of the material. The heating material may be a magnetic material such that penetration by the varying magnetic field causes hysteresis heating of the material. The susceptor may be both conductive and magnetic such that the susceptor can be heated by both heating mechanisms. In this document, a device configured to generate a varying magnetic field is referred to as a magnetic - field generator.

[0096] An aerosol modifier is a substance that is typically located downstream of the aerosol - forming area and is configured to modify the generated aerosol, for example, by changing the taste, flavor, acidity, or another property of the aerosol. The aerosol modifier may be provided in an aerosol - modifier release component that is operable to selectively release the aerosol modifier. For example, the aerosol modifier may be an additive or an adsorbent. For example, the aerosol modifier may include one or more of a flavoring, a coloring agent, water, and a carbon adsorbent. For example, the aerosol modifier may be a solid, a liquid, or a gel. The aerosol modifier may be in the form of a powder, a wire, or a granule. The aerosol modifier may be free of filtering material.

[0097] An aerosol generator is a device configured to cause an aerosol to be formed from an aerosol - forming material. In some embodiments, the aerosol generator is a heater configured to subject the aerosol - forming material to thermal energy in order to release one or more volatiles from the aerosol - forming material to form an aerosol. In some embodiments, the aerosol generator is configured to cause an aerosol to be formed from the aerosol - forming material without heating. For example, the aerosol generator may be configured to subject the aerosol - forming material to one or more of vibration, increased pressure, or electrostatic energy.

[0098] The present disclosure relates to an aerosol supply system (which may also be referred to as a vapor supply system), such as an atomizer or an electronic cigarette. In the following description, the term "electronic cigarette" or "e-cigarette" may sometimes be used, but it will be understood that this term may be used interchangeably with aerosol supply system / device and electronic aerosol supply system / device. Additionally, as is common in the art, the terms "aerosol" and "vapor" and related terms such as "evaporation", "atomization", and "aerosolization" are generally used interchangeably.

[0099] An aerosol supply system (e-cigarette) typically (although not always) includes modular components, which include a reusable device portion and a replaceable (disposable / consumable) cartridge component. Generally, the replaceable cartridge component will include aerosol generating material and an evaporator (which may be collectively referred to as an "atomizer"), and the reusable device portion will include a power source (e.g., a rechargeable power source) and a control circuit. It will be understood that these different portions may include additional elements depending on their functions. For example, the reusable device portion will typically include a user interface for receiving user input and displaying operating state characteristics, and the replaceable cartridge device portion includes a temperature sensor for assisting in temperature control in some cases. The cartridge is electrically and mechanically coupled to the control unit for use, for example, using a thread, a bayonet, or a magnetic coupling with appropriately arranged electrical contacts. When the aerosol generating material in the cartridge is depleted, or when the user wishes to switch to a different cartridge with a different aerosol generating material, the cartridge can be removed from the reusable component, and a replacement cartridge can be attached in its place. Systems and devices conforming to this type of two-piece modular configuration are generally referred to as two-piece systems / devices.

[0100] Electronic cigarettes typically have a generally elongated shape. To provide a specific example, some embodiments of the present disclosure will be considered to include such a generally elongated two-piece system with a disposable cartridge. However, it will be understood that the basic principles described herein can equally apply to different configurations, such as a one-piece system or a modular system including more than two components, a refillable device and a single-use disposable item, and other overall shapes, such as those based on the so-called box-mod high-performance devices that typically have a box-like shape. More generally, it will be understood that certain embodiments of the present disclosure are based on an aerosol supply system that is operationally configured to provide functions in accordance with the principles described herein, and the construction aspects of a system configured to provide the functions of certain embodiments of the present disclosure are not of primary importance.

[0101] As described in the background art, the connection between the pins of the current heating element and the electrodes is carried out by welding, resulting in problems such as complex assembly processes and large system volumes. Therefore, the embodiments of the present invention creatively provide a new aerosol supply system, which opens a limiting hole in the atomizer bracket and realizes the solderless connection between the heating element and the electrodes in the limiting hole, so as to reduce the complexity of the assembly process and reduce the volume of the system.

[0102] The structure of the aerosol supply system of the present invention will be introduced in detail below by means of specific embodiments.

[0103] Figure 1 is a three-dimensional structure diagram of the aerosol supply system provided by the embodiment of the present invention. Figure 2 、 3 are cross-sectional views of the aerosol supply system provided by the embodiment of the present invention in different viewing directions. Referring to Figures 1 to 3 shown, the aerosol supply system is an elongated structure extending along the longitudinal axis. The aerosol supply system includes a proximal end and a distal end facing away from each other in the height direction, and a housing 100 extending between the proximal end and the distal end. The housing 100 is provided with a mouthpiece 101 at the proximal end, and an air outlet 102 is opened on the mouthpiece 101. An air inlet 103 is also opened on the housing 100. The air inlet 103 can be arranged at the distal end as shown in Figure 2 、 3 shown, or can be arranged at other positions of the housing 100.

[0104] A receiving space and an air passage are formed inside the housing 100. A receiving cavity 200 for receiving an aerosol generating material (such as e-liquid), an atomizer 300, a power source (battery assembly) 400, and a controller (control circuit) 500 are provided in the receiving space. The receiving cavity 200, the atomizer 300, the controller 500, and the power source 400 are arranged substantially along the height direction of the system. The power source 400 is configured to supply power to the heating component in the atomizer 300 under the control of the controller 500. An atomization cavity 310 for receiving the heating component is provided inside the atomizer 300. The atomization cavity 310 is in fluid communication with the receiving cavity 200, and the aerosol generating material in the receiving cavity 200 can enter the atomization cavity 310 and be heated by the heating component.

[0105] The air inlet 103, the atomization cavity 310, and the air outlet 102 are connected to form an air passage inside the housing. When the user sucks, external air enters from the air inlet 103, passes through the atomization cavity 310, takes away the aerosol inside, and then flows out from the air outlet 102 to the user.

[0106] In one embodiment of the present invention, the system further includes a first sealing cover 104 for sealing the air outlet 102 and a second sealing cover 105 for sealing the air inlet 103. When the aerosol supply system is not in use, the first sealing cover 104 and the second sealing cover 105 can be covered to ensure safety and hygiene.

[0107] Referring to Figures 1 to 3 as shown, the housing 100 includes two independent parts, namely an upper housing 110 with a mouthpiece 101 and a lower housing 120. An accommodation chamber 200 and an atomizer 300 are provided in the upper housing 110; a power source 400 and a controller 500 are provided in the lower housing 120. The lower end portion of the upper housing 110 is located within the lower housing 120. In an alternative embodiment, the upper housing 110 and the lower housing 120 are substantially non-overlapping in the height direction of the system, and the lower end of the upper housing 110 is connected to the upper end of the lower housing 120 to form the housing 100.

[0108] In one embodiment, the upper housing 110 and the lower housing 120 are detachably connected so that the aerosol generating material or the atomizer 300 etc. within the upper housing 110 can be replaced or the atomizer 300 can be connected to different power sources 400. It can be understood that in other embodiments, the upper housing 110 and the lower housing 120 are permanently connected once assembled.

[0109] In an alternative embodiment, different from Figures 1 - 3 the structure in which the upper and lower housings are independently arranged as shown, the housing 100 can also be configured as an integrally formed independent structure. From the perspective of internal component assembly and reusability, the arrangement of the upper and lower housings has more advantages than an integrally formed housing.

[0110] In other embodiments of the present invention, the aerosol supply system can be a boxed structure, and the atomizer 300 and the power source 400 can be arranged in a lateral direction extending left and right. The housing 100 can be configured as an integrally formed boxed housing. It can also be configured to include two left and right connected housings, with an accommodation chamber 200 and an atomizer 300 provided in one housing and a power source 400 and a controller 500 provided in the other housing. The two left and right housings can be detachably connected. Of course, in an alternative embodiment, the two left and right housings are permanently connected once assembled.

[0111] The mouthpiece 101 can be integrally formed with the housing 100 or removably separable from the housing 100. The separable mouthpiece 101 helps to clean the mouthpiece 101. In addition, setting the separable mouthpiece 101 can help to access the inside of the housing 100 to facilitate replacing the aerosol generating material within the housing 100.

[0112] The power source 400 is configured to supply power to the atomizer 300 and can specifically be a battery assembly. In other examples, the battery can be replaced by a portable power source (for example, a capacitive power storage device such as a supercapacitor or an ultracapacitor), a mechanical power source (a mechanical power spring or a generator), or an alternative chemical energy source (for example, a fuel cell).

[0113] The aerosol - generating material can be solid, powder or liquid. In one embodiment of the present invention, the accommodation chamber 200 is used to accommodate the liquid aerosol - generating material. As Figures 2 - 3 shown, the accommodation chamber 200 includes an outer wall. The outer wall of the accommodation chamber 200 and the housing 100 can be integrally formed, that is, the outer wall forms a part of the housing 100. The outer wall and the housing 100 can also be two independent components, and the housing 100 is provided outside the outer wall. The outer wall covers at least part of the outside of the atomizer 300, and the accommodation chamber 200 is formed by jointly enclosing the outer wall and part of the surface of the atomizer 300.

[0114] To achieve aerosolization, the liquid aerosol - generating material in the accommodation chamber 200 needs to be transported into the atomization chamber 310. For this purpose, the system further includes a liquid inlet structure 600 for transporting the liquid aerosol - generating material from the accommodation chamber 200 to the atomization chamber 310.

[0115] Figure 4 It is a partial structural diagram of the aerosol supply system provided by the embodiment of the present invention, in which the liquid inlet structure 600 is shown. Referring to Figures 2 - 4 shown, the liquid inlet structure 600 provided by the embodiment of the present invention includes a support frame 610, a liquid inlet channel 620, a first liquid inlet hole 630 and an air exchange hole 640. The liquid inlet channel 620 is communicated with both the accommodation chamber 200 and the atomization chamber 310.

[0116] A liquid guiding groove 622 and an annular groove 621 that communicate with each other are formed on the support frame 610. It can be understood that the annular groove 621 is provided on the upper surface of the support frame 610, and this upper surface faces the accommodating cavity 200. The liquid guiding groove 622 can be composed of multiple parts, and at least part of the liquid guiding groove 622 extends along the longitudinal direction of the aerosol supply system, and the annular groove 621 extends along the transverse direction of the aerosol supply system. The liquid guiding groove 622 and the annular groove 621 are formed as the above-mentioned liquid inlet passage 620. The part of the liquid guiding groove 622 that extends along the longitudinal direction of the aerosol supply system is arranged adjacent to the atomizing cavity 310 along the transverse direction of the system. The liquid guiding groove 622 has a first side wall 6211 for enclosing one side of the atomizing cavity 310, and both the first liquid inlet hole 630 and the air exchange hole 640 are provided on the first side wall 6211 and penetrate through the first side wall 6211. Both the first liquid inlet hole 630 and the air exchange hole 640 communicate the liquid guiding groove 622 with the atomizing cavity 310. The aerosol generating material in the accommodating cavity 200 sequentially enters the atomizing cavity 310 through the liquid guiding groove 622 and the first liquid inlet hole 630. The air exchange hole 640 is configured to communicate with the external atmosphere of the aerosol supply system. Therefore, during the use of the system, when the internal pressure of the accommodating cavity 200 becomes smaller as the aerosol generating material is consumed, due to the pressure difference, the external atmosphere will enter the atomizing cavity 310 from the outside, then enter the liquid guiding groove 622 through the air exchange hole 640, and then enter the accommodating cavity 200 through the liquid guiding groove 622 to maintain the hydraulic balance of the accommodating cavity 200.

[0117] In a preferred embodiment of the present invention, along the height direction of the system, the air exchange hole 640 is arranged above the first liquid inlet hole 630, so that the bubbles generated in the aerosol generating material are not easily stuck at the first liquid inlet hole 630, preventing the first liquid inlet hole 630 from being blocked, enabling the aerosol generating material to smoothly enter the atomizing cavity 310 from the accommodating cavity 200, and avoiding affecting the use of the system.

[0118] Furthermore, the system further includes a second airway seal 700 for sealing between the support frame 610 and the accommodating cavity 200. Specifically in implementation, the shape and size of the second airway seal 700 are adapted to the size and shape of the end of the support frame 610 close to the accommodating cavity 200, and no specific limitation is made here. The outer wall of the accommodating cavity 200 covers the periphery of the second airway seal 700, and the part of the outer wall in contact with the second airway seal 700 is in interference fit. In this way, the aerosol generating material in the accommodating cavity 200 can be prevented from leaking and contaminating other components such as the battery assembly in the aerosol supply system. At the same time, in order to achieve the fluid communication between the accommodating cavity 200 and the liquid guiding groove 622, a second liquid inlet hole 710 is opened on the second airway seal 700, so that the aerosol generating material in the accommodating cavity 200 can enter the liquid guiding groove 622 through the second liquid inlet hole 710.

[0119] Figure 5It is a schematic three-dimensional structure diagram of an atomizer of an aerosol supply system provided by an embodiment of the present invention. Figure 6 It is an exploded view of an atomizer of an aerosol supply system provided by an embodiment of the present invention. Figure 7 It is a structural diagram of a heating element provided by an embodiment of the present invention. Referring to Figure 2 、 5 As shown in FIGS. 8-7, the atomizer 300 includes an atomization chamber 310, an atomizer bracket 320 forming the atomization chamber 310, an airway member 330, and a heating assembly disposed inside the atomization chamber 310. As shown in Figure 5 、 6 As shown, the atomizer bracket 320 includes a structural member 321 and a support frame 610 that cooperates with it to form the atomization chamber. The support frame 610 is formed with a receiving groove 611, and the airway member 330 is assembled in the receiving groove 611. The heating assembly is clamped and fixed in the receiving groove 611 by the support frame 610 and the airway member 330. Both the heating assembly and the airway member 330 are connected to the structural member 321 and the support frame 610.

[0120] As shown in Figure 6 As shown, the heating assembly includes a stacked heating element 341 and an oil guiding body 342. An airway is formed between the airway member 330 and the heating element 341. The oil guiding body 342 is disposed on the side of the heating element 341 away from the airway, and the oil guiding body 342 is disposed in a fitting manner on the wall of the support frame 610 provided with a first liquid inlet hole 630.

[0121] The oil guiding body 342 is used to transport the liquid aerosol generating material in the receiving chamber 200 to the heating element 341. In an embodiment of the present invention, the oil guiding body 342 can be an oil guiding body such as cotton or ceramic to achieve oil guiding. In one embodiment of the present invention, the oil guiding body 342 can be a multi-layer porous structure.

[0122] As an illustrative but non-limiting example, the oil guiding rate of the side of the oil guiding body 342 close to the heating element 341 is lower than the oil guiding rate of the side away from the heating element 341, and the oil absorption rate of the side of the oil guiding body 342 close to the heating element 341 is higher than the oil absorption rate of the side away from the heating element 341, so that the oil guiding rate of the part of the oil guiding body 342 close to the heating element 341 is higher, improving its oil guiding efficiency, while the oil absorption rate of the part away from the heating element 341 is higher, increasing the oil absorption amount at the heating element 341.

[0123] In an embodiment of the present invention, a plurality of grooves are provided on the surface of the airway member 330 to collect the condensate formed after the aerosol condenses in the atomization chamber 310 and prevent the condensate from leaking outside the atomization chamber 310.

[0124] In an embodiment of the present invention, as shown in Figure 7As shown, the heating element 341 is a heating mesh. The mesh holes of the heating mesh are any one of circular or polygonal shapes. The heating element 341 includes a main body portion 3411 and pins 3412 extending from the main body portion. The heating element 341 is integrally flat, and the main body portion 3411 extends along the height direction of the system. Both pins 3412 are L-shaped and semi-enclose the main body portion 3411 in the diagonal direction. The pins 3412 of the heating element 341 can be in the shape of columns or sheets, etc.

[0125] As an illustrative but non-limiting example, the two pins 3412 of the heating element 341 can be the same or different. As Figure 7 shows, in an embodiment of the present invention, the two pins 3412 have different shapes.

[0126] As Figures 5 - 6 shown, the atomizer 300 further includes a base assembly 350, which is detachably assembled on the atomizer bracket 320 to define the bottom surface of the atomization chamber 310. The base assembly 350 is provided with an electrode hole for the electrode 352 to pass through and extend towards the atomization chamber 310.

[0127] As Figure 6 shown, the base assembly 350 includes an atomization chamber bottom cover 353 and a first airway seal 354 provided on the side of the atomization chamber bottom cover 353 facing the atomization chamber 310. Corresponding electrode holes are provided on both the atomization chamber bottom cover 353 and the first airway seal 354 for the electrode 352 to pass through.

[0128] The power supply 400 is electrically connected to the heating element 341 through the connection between the electrode 352 and the pin 3412. Figure 8 is a schematic diagram of the contact between the electrode and the pin of the aerosol supply system provided by the embodiment of the present invention in the limiting hole. Figure 9 is a schematic diagram of the pin of the aerosol supply system provided by the embodiment of the present invention in the limiting hole. Figure 10 is a schematic diagram of the contact between the electrode and the pin of the aerosol supply system provided by the embodiment of the present invention. Referring to Figures 8 - 10 shown, a limiting hole 800 is provided on the atomizer bracket. The limiting hole 800 can be specifically provided on the support frame 610. A first opening 810 is provided on the limiting hole 800. The electrode 352 enters the limiting hole 800 through the first opening 810, and the pin 3412 also extends into the limiting hole 800. The electrode 352 and the pin 3412 are connected without soldering in the limiting hole 800.

[0129] In an embodiment of the present invention, the electrode 352 extends from the distal end to the proximal end, and the pin 3412 extends from the proximal end to the distal end. At this time, the first opening 810 is provided on the side of the support frame 610 facing the distal end so that the electrode 352 can directly extend into the first opening 810.

[0130] Of course, in other embodiments of the present invention, the first opening 810 may be provided at other positions of the support frame 610. For example, the first opening 810 is provided on the side of the support frame 610 facing the proximal end. At this time, the electrode can extend from the distal end to the proximal end and bend into the first opening 810.

[0131] In another embodiment of the present invention, the power supply 400 and the atomizer 300 are arranged substantially along the transverse direction of the system, and both the heating element 341 and the electrode 352 extend substantially along the transverse direction of the system, and the heating element 341 is basically laid flat in the atomization chamber 310. At this time, the limiting hole 800 can be arranged along the transverse direction of the system.

[0132] Compared with the electrode 352, the pin 3412 is more easily bent. Therefore, in the embodiment of the present invention, the first opening 810 is preferably provided at one end of the atomizer bracket 320 facing the electrode 352.

[0133] Considering that there are various possible arrangement ways for the power supply 400, the atomizer 300, the heating element 341 and the electrode 352, the extending direction of the limiting hole 800 and the orientation of the first opening 810 in the present invention can be set according to specific needs. The present invention does not make specific limitations on this.

[0134] The following embodiments of the present invention provide several forms of solderless connection between the electrode 352 and the pin 3412.

[0135] In an embodiment of the present invention, the contact connection between the electrode 352 and the pin 3412 in the limiting hole 800 can be realized by pressure abutment. At this time, both the electrode 352 and the pin 3412 are in pressure contact with the inner wall surface of the limiting hole 800, and the electrode 352 and the pin 3412 are in pressure contact with each other under the pressure of the inner wall surface. In this way, a stable electrical connection between the electrode 352 and the pin 3412 in the limiting hole 800 is achieved.

[0136] In another embodiment of the present invention, the contact connection between the electrode 352 and the pin 3412 in the limiting hole 800 can be realized by adhesive connection. At least part of the side surfaces of the electrode 352 and the pin 3412 in contact are adhesively connected by an adhesive to achieve the stability of the connection between the electrode 352 and the pin 3412. In a specific embodiment, the adhesive is conductive, and the surface where the electrode 352 and the pin 3412 are adhesively connected is also the electrical connection surface of the two. In another specific embodiment, the electrical connection surface of the electrode 352 and the pin 3412 is a surface other than the adhesively connected surface.

[0137] In another embodiment of the present invention, the contact connection between the electrode 352 and the pin 3412 within the limit hole 800 can be achieved through magnetic attraction connection. By providing magnetic attraction structures or magnetic attraction surfaces on the electrode 352 and the pin 3412, a stable connection between the electrode 352 and the pin 3412 is realized. And outside the magnetic attraction structure or magnetic attraction surface, the side surfaces of the electrode 352 and the pin 3412 can be made to contact to achieve electrical connection.

[0138] In another embodiment of the present invention, the contact connection between the electrode 352 and the pin 3412 within the limit hole 800 can be achieved through snap connection. By providing mating snap structures on the electrode 352 and the pin 3412, a stable connection between the electrode 352 and the pin 3412 is realized. Specifically, the snap structure can be a pin extending from the electrode 352 and a hole provided on the pin 3412 that mates with the pin. Electrical connection is achieved through the snap connection of the pin and the hole and the contact between the side surfaces of the electrode 352 and the pin 3412.

[0139] In another embodiment of the present invention, the contact connection between the electrode 352 and the pin 3412 within the limit hole 800 can also be achieved through elastic connection, which will be described in detail in subsequent embodiments.

[0140] When connecting the electrode 352 and the pin 3412, one or a combination of the above-mentioned methods can be adopted.

[0141] By opening a limit hole in the atomizer bracket, the pins of the heating element and the electrodes are limited within the limit hole, realizing the limitation of the pins and the electrodes, and achieving solderless connection based on the limiting effect of the limit hole. This solderless connection can specifically be pressure abutment, snap connection, elastic interference fit, etc. Compared with the prior art, these connection methods all eliminate the soldering process and simplify the complexity of assembly; and since there is no need to prepare dimensions for soldering, the volume of the system can be designed to be reduced accordingly.

[0142] In the embodiment of the present invention, the pin 3412 and the electrode 352 can enter the limit hole 800 through the same or different openings.

[0143] In one embodiment of the present invention, the pin 3412 and the electrode 352 enter the limit hole 800 through the same opening. As Figure 8 、 9 shown, the support frame 610 is provided with a first opening 810 facing the distal end. The electrode 352 extends into the first opening 810 in the direction from the distal end to the proximal end, and the pin 3412 extends and bends into the first opening 810 in the direction from the proximal end to the distal end. Both the electrode 352 and the pin 3412 enter the limit hole 800 through the first opening 810. The side surface of the pin 3412 contacts and connects with the side surface of the electrode 352 within the limit hole 800. As Figure 10 shows the state when the two are in contact.

[0144] In one embodiment of the present invention, the portion of the electrode 352 inserted into the limiting hole 800 is substantially parallel to the portion of the pin 3412 bent into the limiting hole 800, for example, the angle between the two is set between -5° and 5°. Based on the substantially parallel setting of this embodiment, the contact area between the pin 3412 and the electrode 352 can be increased, thereby improving the stability of the electrical connection.

[0145] In one embodiment of the present invention, the shapes of the two sides of the pin 3412 in contact with the electrode 352 are adapted to each other. For example, adapted concave-convex surfaces, adapted arc surfaces, adapted flat surfaces, etc. By adapting the shapes of the two sides, the contact area between the pin 3412 and the electrode 352 can be increased, improving the tightness of the connection between the two, and thus improving the stability of the electrical connection.

[0146] In one embodiment of the present invention, the bent corner of the pin 3412 has a maximum thickness and / or a maximum width. Based on the setting of this embodiment, the strength of the bent portion can be improved, the probability of breakage at the bent portion can be reduced, and the stability of the electrical connection can be improved.

[0147] In one embodiment of the assembly of the electrode 352 and the pin 3412, the pin 3412 may have a lateral length exposed in the first opening 810. During the process of the electrode 352 extending into the first opening 810, it abuts against the lateral length of the pin 3412 to bend it and then enters the limiting hole 800 through the first opening 810. Based on the setting of this embodiment, the pin 3412 can be bent while the electrode 352 extends into the limiting hole, without bending the pin 3412 in advance, further simplifying the assembly process.

[0148] In another embodiment of the present invention, the pin 3412 and the electrode 352 can enter the limiting hole through different openings. Figures 11 - 13 FIG. is a schematic diagram of the electrode and the pin of the aerosol supply system provided by the embodiment of the present invention entering the limiting hole through different openings. Figures 11 - 13 It is only used to show the positional relationship of each component and does not limit the specific shape of each component. Refer to Figures 11 - 13 As shown, the atomizer bracket is further provided with a through hole 900 communicating with the limiting hole 800. There is an included angle between the axis of the through hole 900 and the axis of the limiting hole 800. The through hole 900 has a second opening 910 facing away from the limiting hole 800. The pin 3412 is inserted into the through hole 900 from the second opening 910 and at least partially extends into the limiting hole 800 via the through hole 900. The two achieve solderless connection in the limiting hole 800. In this embodiment, the pin and the electrode are configured to enter the limiting hole through different openings, which improves the flexibility of the position setting of the pin and the electrode, and facilitates the pin and the electrode to enter the limiting hole through their respective closer openings relative to the atomizer bracket, reducing the sizes of the pin and the electrode, and thus further reducing the volume of the system.

[0149] As Figure 11 shown, in one embodiment of the present invention, the pin 3412 has a first portion 12 extending into and located within the through-hole and a second portion 11 extending into and located within the limiting hole. There is a bending angle between the first portion 12 and the second portion 11. After the pin 3412 is bent into the limiting hole 800, the side surface of the electrode 352 contacts the side surface of the second portion 11 of the pin 3412.

[0150] In one embodiment of the present invention, the portion of the electrode 352 inserted into the limiting hole 800 is substantially parallel to the second portion 11 of the pin 3412, for example, the angle between the two is set between -5° and 5°. Based on the substantially parallel setting of this embodiment, the contact area between the pin and the electrode can be increased, thereby improving the stability of the electrical connection.

[0151] In one embodiment of the present invention, the shapes of the two side surfaces of the second portion 11 of the pin 3412 in contact with the electrode 352 are adapted to each other. For example, adapted concave-convex surfaces, adapted arc surfaces, adapted flat surfaces, etc. By adapting the shapes of the two side surfaces, the contact area between the pin and the electrode can be increased, the tightness of the connection between the pin and the electrode can be improved, and thus the stability of the electrical connection can be improved.

[0152] In one embodiment of the present invention, the bending angle of the first portion 12 and the second portion 11 of the pin 3412 has a maximum thickness and / or a maximum width. Based on the setting of this embodiment, the strength of the bending portion can be improved, the probability of breakage at the bending portion can be reduced, and the stability of the electrical connection can be improved.

[0153] In one embodiment of the present invention, in the cross-sectional direction of the limiting hole 800, the pin 3412 has a lateral length that can be exposed within the hole of the limiting hole 800; the electrode 352 abuts against this lateral length during the process of extending into the limiting hole 800 to bend the pin 3412 to form the second portion 11. Based on the setting of this embodiment, the electrode 352 can abut against the pin 3412 while extending into the limiting hole 800 to bend and form the second portion 11 electrically connected to the electrode 352, without the need to bend the pin 3412 in advance, further simplifying the assembly process.

[0154] As Figure 12 shown, in another embodiment of the present invention, the pin 3412 has a first portion 12 extending into and located within the through-hole 900 and a second portion 11 extending into and located within the limiting hole 800. The first portion 12 and the second portion 11 are in the same plane. The side surface of the second portion 11 contacts the end surface of the electrode 352.

[0155] As Figure 13As shown, in another embodiment of the present invention, the pin 3412 has a first portion 12 extending into and located within the through hole 900 and a second portion 11 extending into and located within the limiting hole 800. The first portion 12 and the second portion 11 are in the same plane. The end face of the second portion 11 contacts the side face of the electrode 352.

[0156] To increase the stability of the connection, when the end face of the second portion 11 of the pin 3412 contacts the side face of the electrode 352, a recess may be formed in the end face of the second portion 11 to form an open ring, and the electrode 352 is inserted into the open ring. The size of the opening of the open ring may be set to prevent the electrode from moving out of the opening.
