The side of the absorbent liquid 51 in contact with the heating element 52 forms an atomization surface 331. The absorbent liquid 51 absorbs liquid matrix from the liquid storage chamber 110 and conducts the liquid matrix to the heating element 52. The heating element 52 heats and atomizes the liquid matrix adsorbed by the absorbent liquid 51 after being energized. In some embodiments, the absorbent liquid 51 may be made of porous materials such as porous ceramics and absorbent cotton, so that a large number of micropores are formed inside the absorbent liquid 51 and have a certain porosity. Through the capillary action of the micropores, the absorbent liquid 51 can absorb and cache the liquid matrix.
在本实施例中，吸液体51为呈长方形板状的多孔陶瓷并可沿竖直方向设置，吸液体51上沿竖直方向设置的一个表面界定出雾化面331。在其他实施例中，吸液体51也可与竖直方向呈一定夹角倾斜设置，相应地，吸液体51上与竖直方向呈夹角设置的一个表面界定出雾化面331。In this embodiment, the liquid absorbing body 51 is a porous ceramic in the shape of a rectangular plate and can be arranged in the vertical direction, and a surface of the liquid absorbing body 51 arranged in the vertical direction defines the atomization surface 331. In other embodiments, the liquid absorbing body 51 can also be arranged at a certain angle to the vertical direction, and accordingly, a surface of the liquid absorbing body 51 arranged at an angle to the vertical direction defines the atomization surface 331.
基座30可包括基部32、由基部32向下延伸的连接部31以及由基部32向上延伸的延伸部33。基部32至少部分嵌置于筒状外壳11的下端开口处，基部32的横截面外轮廓的形状与筒状外壳11的横截面内轮廓的形状相适配，使得基部32的外周面与筒状外壳11的内周面密封配合，以防止漏液。具体地，在本实施例中，基部32的横截面外轮廓大致呈圆形。在一些实施例中，基部32上还可套设有一密封圈34，密封圈34可采用硅胶等弹性材料制成，通过密封圈34提高基部32与筒状外壳11之间的密封性。在本实施例中，密封圈34为O型密封圈，基部32的外周面还可内凹形成有一用于供密封圈34套装的凹槽324，方便密封圈34的安装固定。The base 30 may include a base 32, a connecting portion 31 extending downward from the base 32, and an extending portion 33 extending upward from the base 32. The base 32 is at least partially embedded in the lower end opening of the cylindrical shell 11, and the shape of the outer contour of the cross section of the base 32 is adapted to the shape of the inner contour of the cross section of the cylindrical shell 11, so that the outer peripheral surface of the base 32 is sealed with the inner peripheral surface of the cylindrical shell 11 to prevent leakage. Specifically, in the present embodiment, the outer contour of the cross section of the base 32 is roughly circular. In some embodiments, a sealing ring 34 may be sleeved on the base 32, and the sealing ring 34 may be made of elastic materials such as silicone, and the sealing ring 34 improves the sealing between the base 32 and the cylindrical shell 11. In the present embodiment, the sealing ring 34 is an O-type sealing ring, and the outer peripheral surface of the base 32 may also be concave to form a groove 324 for the sealing ring 34 to be set, so as to facilitate the installation and fixation of the sealing ring 34.
进气通道320可沿纵向形成于基部32上，其可包括第一进气道321以及设置于第一进气道321的***的多个第二进气道322。第一进气道321的进气面积（即横截面积）大于各第二进气道322的进气面积（即横截面积）。第一进气道321的主要作用为，第一进气道321中的气流进入雾化腔330后将雾化腔330内的烟气带出至出气通道120。第一进气道321的中心线与雾化面331之间具有一定的距离，一方面使得第一进气道321中的气流不直接吹向雾化面331，避免降低雾化面331的表面温度而影响雾化，另一方面能够给从雾化面331射出的烟气发展空间，避免直接将烟气液滴冲回雾化面331。在一些实施例中，第一进气道321的中心线与雾化面331之间的距离可以为0.3mm~1.8mm。The air inlet channel 320 may be formed on the base 32 in the longitudinal direction, and may include a first air inlet channel 321 and a plurality of second air inlet channels 322 arranged on the periphery of the first air inlet channel 321. The air inlet area (i.e., cross-sectional area) of the first air inlet channel 321 is greater than the air inlet area (i.e., cross-sectional area) of each second air inlet channel 322. The main function of the first air inlet channel 321 is that the airflow in the first air inlet channel 321 brings the smoke in the atomizing chamber 330 out to the air outlet channel 120 after entering the atomizing chamber 330. There is a certain distance between the center line of the first air inlet channel 321 and the atomizing surface 331. On the one hand, the airflow in the first air inlet channel 321 does not blow directly to the atomizing surface 331, avoiding lowering the surface temperature of the atomizing surface 331 and affecting atomization. On the other hand, it can provide space for the smoke ejected from the atomizing surface 331 to develop, avoiding directly flushing the smoke droplets back to the atomizing surface 331. In some embodiments, the distance between the center line of the first air inlet 321 and the atomizing surface 331 may be 0.3 mm to 1.8 mm.
第一进气道321的横截面形状不受限制，其可以为矩形、圆形、椭圆形等各种规则或不规则形状。在一些实施例中，第一进气道321的横截面形状可与雾化腔330的横截面形状相同或相似，有利于更加充分地带走雾化腔330内的烟气。具体地，在本实施例中，雾化腔330的横截面形状为类矩形，第一进气道321的横截面形状也为类矩形。The cross-sectional shape of the first air inlet 321 is not limited, and it can be various regular or irregular shapes such as rectangle, circle, ellipse, etc. In some embodiments, the cross-sectional shape of the first air inlet 321 can be the same as or similar to the cross-sectional shape of the atomizing chamber 330, which is conducive to more fully taking away the smoke in the atomizing chamber 330. Specifically, in this embodiment, the cross-sectional shape of the atomizing chamber 330 is a quasi-rectangular shape, and the cross-sectional shape of the first air inlet 321 is also a quasi-rectangular shape.
多个第二进气道322可以围绕成一圈排布，且可靠近雾化腔330的腔壁设置。该多个第二进气道322的作用有：第一，由该多个第二进气道322进入雾化腔330的气流可以在烟气和雾化腔330的腔壁之间形成气流屏障以形成气帘，该气帘能够减少或避免烟气撞击在雾化腔330的腔壁上而形成的冷凝，从而减少烟气损失，提高传输效率；第二，该多个第二进气道322的气流可包裹第一进气道321形成的烟气气流，达到聚拢烟气、避免烟气发散的作用，从而提高烟气浓度，同时使较小粒径的液滴有机会结合成较大粒径的液滴；第三，在相同流量下，该多个第二进气道322能够起到减速气流的作用，有利于烟气混合（单位体积空气中气溶胶含量高）及液滴融合；第四，该多个第二进气道322还能够使得烟气入嘴分布相对均匀。The plurality of second air inlets 322 can be arranged in a circle and can be arranged close to the wall of the atomizing chamber 330. The functions of the plurality of second air inlets 322 are as follows: first, the airflow entering the atomizing chamber 330 from the plurality of second air inlets 322 can form an airflow barrier between the smoke and the wall of the atomizing chamber 330 to form an air curtain, which can reduce or avoid condensation formed by the smoke hitting the wall of the atomizing chamber 330, thereby reducing smoke loss and improving transmission efficiency; second, the airflow of the plurality of second air inlets 322 can wrap the smoke airflow formed by the first air inlet 321, so as to gather the smoke and prevent the smoke from dispersing, thereby increasing the smoke concentration and giving droplets of smaller particle size the opportunity to combine into droplets of larger particle size; third, at the same flow rate, the plurality of second air inlets 322 can play the role of decelerating the airflow, which is beneficial to smoke mixing (high aerosol content per unit volume of air) and droplet fusion; fourth, the plurality of second air inlets 322 can also make the smoke inlet distribution relatively uniform.
一般而言，在流量固定的情况下，增大第二进气道322的进气面积，则会导致进气速度下降，有利于烟气混合及液滴融合，但进气速度过小则会导致气帘流速过小，影响气流屏障的效果。此外，第二进气道322的进气面积过小，还会导致抽吸时的气流阻力太大，抽吸体验不佳。在一些实施例中，该多个第二进气道322的总进气面积与第一进气道321的进气面积之比可以为0.5~6。Generally speaking, when the flow rate is fixed, increasing the intake area of the second air inlet duct 322 will cause the intake speed to decrease, which is beneficial to smoke mixing and droplet fusion, but if the intake speed is too low, the air curtain flow rate will be too low, affecting the effect of the airflow barrier. In addition, if the intake area of the second air inlet duct 322 is too small, it will also cause too much airflow resistance during suction, resulting in a poor suction experience. In some embodiments, the ratio of the total intake area of the multiple second air inlet ducts 322 to the intake area of the first air inlet duct 321 can be 0.5~6.
第二进气道322的横截面形状不受限制，其可以为矩形、圆形或椭圆形等各种规则或不规则形状。多个第二进气道322围绕成的形状也不受限制，例如，其可围绕成矩形、圆形或椭圆形等等。在一些实施例中，多个第二进气道322围绕成的形状可与第一进气道321的横截面形状以及雾化腔330的横截面形状相同或相似，在雾化腔330的腔壁面形成的气流屏障效果较好，且烟气入嘴分布更均匀。在本实施例中，各第二进气道322的横截面形状均为圆形且具有相同的孔径，且多个第二进气道322的连线形成一个类矩形。在其他实施例中，该多个第二进气道322也可具有不同的横截面形状和/或不同的横截面积。The cross-sectional shape of the second air inlet 322 is not limited, and it can be various regular or irregular shapes such as rectangle, circle or oval. The shape formed by the multiple second air inlets 322 is also not limited, for example, it can be surrounded by a rectangle, circle or oval, etc. In some embodiments, the shape formed by the multiple second air inlets 322 can be the same or similar to the cross-sectional shape of the first air inlet 321 and the cross-sectional shape of the atomizing chamber 330, and the airflow barrier formed on the cavity wall of the atomizing chamber 330 has a better effect, and the smoke inlet is more evenly distributed. In this embodiment, the cross-sectional shape of each second air inlet 322 is circular and has the same aperture, and the connection line of the multiple second air inlets 322 forms a quasi-rectangular shape. In other embodiments, the multiple second air inlets 322 may also have different cross-sectional shapes and/or different cross-sectional areas.
第一进气道321的上端具有第一出气口3210，第一进气道321中的气流通过第一出气口3210流入至雾化腔330。第二进气道322的上端具有第二出气口3220，第二进气道322中的气流通过第二出气口3220流入至雾化腔330。该第一出气口3210可凸出于第二出气口3220设置，即第一出气口3210所在的第一端面3211的位置高于第二出气口3220所在的第二端面3221的位置。由于第一进气道321的横截面积大于第二进气道322的横截面积，第一出气口3210凸出设置可以避免冷凝液从横截面积更大的第一出气口3210漏出。The upper end of the first air inlet 321 has a first air outlet 3210, and the airflow in the first air inlet 321 flows into the atomizing chamber 330 through the first air outlet 3210. The upper end of the second air inlet 322 has a second air outlet 3220, and the airflow in the second air inlet 322 flows into the atomizing chamber 330 through the second air outlet 3220. The first air outlet 3210 can be arranged protruding from the second air outlet 3220, that is, the position of the first end face 3211 where the first air outlet 3210 is located is higher than the position of the second end face 3221 where the second air outlet 3220 is located. Since the cross-sectional area of the first air inlet 321 is larger than the cross-sectional area of the second air inlet 322, the protruding arrangement of the first air outlet 3210 can prevent the condensate from leaking from the first air outlet 3210 with a larger cross-sectional area.
在本实施例中，第一端面3211、第二端面3221均形成于基部32上，第一端面3211、第二端面3221界定出雾化腔330的至少部分底边界。雾化腔330在基部32上的正投影覆盖第一出气口3210和多个第二出气口3220。基部32的上端面还可下凹形成有一储液槽323，该储液槽323可用于容纳一定量的冷凝液，以减少漏液。第一端面3211和/或第二端面3221可向储液槽323倾斜设置，以利于将第一端面3211和/或第二端面3221上的冷凝液在重力的作用下引导至储液槽323中，减小冷凝液从第一出气口3210和/或多个第二出气口3220漏出。具体地，在本实施例中，第一端面3211、第二端面3221均为平面且朝向储液槽323倾斜设置。可以理解地，在其他实施例中，第一端面3211和/或第二端面3221也可以为倾斜设置的曲面。In the present embodiment, the first end face 3211 and the second end face 3221 are both formed on the base 32, and the first end face 3211 and the second end face 3221 define at least part of the bottom boundary of the atomizing chamber 330. The orthographic projection of the atomizing chamber 330 on the base 32 covers the first air outlet 3210 and the plurality of second air outlets 3220. The upper end face of the base 32 may also be concave to form a reservoir 323, which may be used to accommodate a certain amount of condensate to reduce leakage. The first end face 3211 and/or the second end face 3221 may be tilted toward the reservoir 323, so as to facilitate guiding the condensate on the first end face 3211 and/or the second end face 3221 to the reservoir 323 under the action of gravity, thereby reducing the leakage of condensate from the first air outlet 3210 and/or the plurality of second air outlets 3220. Specifically, in this embodiment, the first end surface 3211 and the second end surface 3221 are both planes and are inclined toward the liquid storage tank 323. It can be understood that in other embodiments, the first end surface 3211 and/or the second end surface 3221 can also be inclined curved surfaces.

The extension portion 33 and the liquid storage tank 323 can be respectively located at two opposite radial sides of the base 32. The extension portion 33 has a first side 332 and a second side 333.

The second side surface 333 may also be concave to form a plurality of liquid storage channels 336, and the condensate leaked to the second side surface 333 may be stored in the plurality of liquid storage channels 336 to reduce leakage. Specifically, each liquid storage channel 336 extends along the circumference of the second side surface 333, and the plurality of liquid storage channels 336 are evenly spaced and arranged in the vertical direction. Preferably, the liquid storage channel 336 is a capillary channel, which can absorb the condensate on the second side surface 333 into the liquid storage channel 336 by capillary force.

It can be understood that in other embodiments, a porous structural member such as a liquid-absorbing cotton may also be arranged in the leakproof liquid chamber 812 to store the condensate, and at this time, the capillary groove 8121 may or may not be arranged in the leakproof liquid chamber 812.
在一些实施例中，发热座80上还可形成有换气通道83，该换气通道83将储液腔110与外界大气相连通，用于平衡储液腔110内的压力，解决因储液腔110内负压过大而不能稳定下液的问题。具体地，换气通道83可包括依次连通的第一换气道831、第二换气道832、第三换气道833、第四换气道834，第一换气道831与储液腔110相连通，第四换气道834可与进气通道320相连通。第一换气道831沿横向延伸，其可由发热座80的顶面下凹形成。第二换气道832沿纵向延伸，其可由发热座80的周向一侧面内凹形成。第二换气道832的上端与第一换气道831相连通，下端与第三换气道833相连通。第三换气道833沿横向延伸，其可由发热座80的周向一侧面向内延伸一段长度。第四换气道834沿纵向延伸，其可由发热座80的底面沿纵向向上延伸至与第三换气道833相连通。In some embodiments, a ventilation channel 83 may also be formed on the heating seat 80, and the ventilation channel 83 connects the liquid storage chamber 110 with the outside atmosphere, and is used to balance the pressure in the liquid storage chamber 110, and solve the problem that the liquid cannot be stably discharged due to excessive negative pressure in the liquid storage chamber 110. Specifically, the ventilation channel 83 may include a first ventilation channel 831, a second ventilation channel 832, a third ventilation channel 833, and a fourth ventilation channel 834 that are connected in sequence, the first ventilation channel 831 is connected to the liquid storage chamber 110, and the fourth ventilation channel 834 can be connected to the air inlet channel 320. The first ventilation channel 831 extends in the horizontal direction, and it can be formed by the concave top surface of the heating seat 80. The second ventilation channel 832 extends in the longitudinal direction, and it can be formed by the concave side of the circumferential direction of the heating seat 80. The upper end of the second ventilation channel 832 is connected to the first ventilation channel 831, and the lower end is connected to the third ventilation channel 833. The third air exchange passage 833 extends in the transverse direction and can extend inwardly from one circumferential side surface of the heating seat 80 . The fourth air exchange passage 834 extends in the longitudinal direction and can extend upward from the bottom surface of the heating seat 80 to communicate with the third air exchange passage 833 .
在一些实施例中，雾化主体20还可包括套设于主体部81上的密封套90。密封套90可采用硅胶等弹性材料制成，密封套90密封地设置于壳体10的内壁面以及主体部81的外壁面之间，以密封储液腔110，并将防漏液腔812在主体部81的侧面形成的两个敞开口密封住。密封套90上分别对应下液孔810、通气孔811以及第一换气道831沿纵向贯穿形成有进液孔910、出气孔911以及换气孔913。通气管道12的下端可插置于出气孔911中，且通气管道12的外壁面可与出气孔911的孔壁面密封配合。In some embodiments, the atomizing body 20 may further include a sealing sleeve 90 sleeved on the main body 81. The sealing sleeve 90 may be made of an elastic material such as silicone, and the sealing sleeve 90 is sealingly arranged between the inner wall surface of the housing 10 and the outer wall surface of the main body 81 to seal the liquid storage chamber 110 and seal the two openings formed by the leak-proof liquid chamber 812 on the side of the main body 81. The sealing sleeve 90 is respectively provided with a liquid inlet hole 910, an air outlet hole 911 and an air exchange hole 913 that are formed longitudinally through the lower liquid hole 810, the air vent 811 and the first air exchange channel 831. The lower end of the ventilation pipe 12 can be inserted into the air outlet hole 911, and the outer wall surface of the ventilation pipe 12 can be sealed with the hole wall surface of the air outlet hole 911.
在一些实施例中，密封套90的顶部还可形成有导液面9121，该导液面9121与储液腔110的底部相连通并可朝向进液孔910倾斜设置。具体地，导液面9121可以为倾斜设置的平面或者曲面，且可环绕于出气孔911设置。倾斜设置的导液面9121一方面能够使得导液面9121上的液体基质能够在重力的作用下流向进液孔910，提高导液效果，另一方面还能够使得在雾化器100倾斜抽吸时，液体基质可以沿着导液面9121进入进液孔910中，防止出现在倾斜抽吸时出现缺液的情况。在本实施例中，密封套90的顶面下凹形成有导液槽912，该导液槽912的底面形成导液面9121，从而使得出气孔911所在的平面高于导液面9121，避免导液面9121上的液体基质从出气孔911泄露。可以理解地，在其他实施例中，导液面9121也可形成于主体部81上。In some embodiments, the top of the sealing sleeve 90 may also be formed with a liquid guide surface 9121, which is connected to the bottom of the liquid storage chamber 110 and may be inclined toward the liquid inlet hole 910. Specifically, the liquid guide surface 9121 may be an inclined plane or curved surface, and may be arranged around the air outlet hole 911. The inclined liquid guide surface 9121 can, on the one hand, allow the liquid matrix on the liquid guide surface 9121 to flow to the liquid inlet hole 910 under the action of gravity, thereby improving the liquid guide effect. On the other hand, when the atomizer 100 is tilted for suction, the liquid matrix can enter the liquid inlet hole 910 along the liquid guide surface 9121, thereby preventing the occurrence of a lack of liquid during tilted suction. In this embodiment, the top surface of the sealing sleeve 90 is concave to form a liquid guide groove 912, and the bottom surface of the liquid guide groove 912 forms the liquid guide surface 9121, so that the plane where the air outlet hole 911 is located is higher than the liquid guide surface 9121, thereby preventing the liquid matrix on the liquid guide surface 9121 from leaking from the air outlet hole 911. It can be understood that in other embodiments, the liquid guiding surface 9121 can also be formed on the main body 81.
在一些实施例中，雾化主体20还可包括绝缘垫70，绝缘垫70可采用硅胶等绝缘弹性耐高温材料制成，雾化芯50经由绝缘垫70抵靠在发热座80上。绝缘垫70一方面能够防止漏液，另一方面可以保护雾化芯50在安装过程中不被挤压破碎。绝缘垫70可呈框状，其内形成有一进液口71，以将下液孔810与吸液体51相连通。绝缘垫70的外轮廓形状可与吸液体51的形状相同或相似，在本实施例中，吸液体51呈长方体片状，绝缘垫70呈长方形框状。In some embodiments, the atomizing body 20 may further include an insulating pad 70, which may be made of an insulating, elastic, and high-temperature resistant material such as silicone, and the atomizing core 50 is abutted against the heating seat 80 via the insulating pad 70. On the one hand, the insulating pad 70 can prevent liquid leakage, and on the other hand, it can protect the atomizing core 50 from being squeezed and crushed during installation. The insulating pad 70 may be frame-shaped, and a liquid inlet 71 is formed therein to connect the lower liquid hole 810 with the liquid absorption liquid 51. The outer contour shape of the insulating pad 70 may be the same as or similar to the shape of the liquid absorption liquid 51. In the present embodiment, the liquid absorption liquid 51 is in the shape of a rectangular sheet, and the insulating pad 70 is in the shape of a rectangular frame.
在一些实施例中，雾化主体20还可包括导液件60，该导液件60设置于吸液体51与下液孔810相连通的一侧，其能够将来自下液孔810中的液体基质快速均匀地传导至吸液体51。导液件60可采用多孔陶瓷、导液棉等多孔材料制成，其可收容于安装腔820中并可呈长方形板状。In some embodiments, the atomizing body 20 may further include a liquid guide 60, which is disposed on a side where the liquid absorbing body 51 is connected to the lower liquid hole 810, and can quickly and evenly conduct the liquid matrix from the lower liquid hole 810 to the liquid absorbing body 51. The liquid guide 60 may be made of porous materials such as porous ceramics and liquid guide cotton, which may be accommodated in the mounting cavity 820 and may be in the shape of a rectangular plate.
在一些实施例中，雾化器100还可包括两个电极组件40，该两个电极组件40用于将发热体52的正极两极与电源装置200电连接。可以理解地，在其他实施例中，电极组件40的数量也可以为一个或两个以上。每一电极组件40均可包括导电片和/或导电柱和/或导线。In some embodiments, the atomizer 100 may further include two electrode assemblies 40, which are used to electrically connect the positive electrodes of the heating element 52 to the power supply device 200. It can be understood that in other embodiments, the number of electrode assemblies 40 may also be one or more than two. Each electrode assembly 40 may include a conductive sheet and/or a conductive column and/or a wire.
具体地，在本实施例中，每一电极组件40均包括用于与发热体52电连接的第一电极41、用于外接电源的第二电极43以及连接第一电极41和第二电极43的电极连接件42。该第一电极41为横向设置的导电柱，其可具有弹性也可不具有弹性。延伸部33上可形成有分别供两个第一电极41插装的两个第一电极孔334。第一电极41的一端插装于第一电极孔334中，另一端抵紧于发热体52上并与发热体52接触导通，从而将雾化芯50经由绝缘垫70抵紧在发热座80上。由于绝缘垫70具有一定的弹性，从而能够吸收挤压应力，避免雾化芯50破裂，并保证第一电极41与发热体52之间电连接的可靠性。此外，由于第一电极41是固定设置在基座30中，其不会出现由于雾化芯50的温度升高而出现形变的问题，从而不会出现电连接失效的问题。可以理解地，在其他实施例中，也可不设置绝缘垫70，此时，第一电极41较佳地具有弹性，从而能够弹性抵紧雾化芯50。Specifically, in the present embodiment, each electrode assembly 40 includes a first electrode 41 for electrically connecting to the heating element 52, a second electrode 43 for an external power supply, and an electrode connector 42 connecting the first electrode 41 and the second electrode 43. The first electrode 41 is a conductive column arranged horizontally, which may be elastic or inelastic. Two first electrode holes 334 for inserting two first electrodes 41 may be formed on the extension portion 33. One end of the first electrode 41 is inserted into the first electrode hole 334, and the other end is pressed against the heating element 52 and is in contact with the heating element 52, so that the atomizer core 50 is pressed against the heating seat 80 via the insulating pad 70. Since the insulating pad 70 has a certain elasticity, it can absorb the extrusion stress, avoid the atomizer core 50 from breaking, and ensure the reliability of the electrical connection between the first electrode 41 and the heating element 52. In addition, since the first electrode 41 is fixedly arranged in the base 30, it will not be deformed due to the increase in the temperature of the atomizer core 50, so that the problem of electrical connection failure will not occur. It is understandable that in other embodiments, the insulating pad 70 may not be provided. In this case, the first electrode 41 is preferably elastic so as to be able to elastically press against the atomizer core 50 .
电极连接件42可以为导电金属片或者导线。第二电极43可以为导电柱并沿纵向设置于基座30中，第二电极43的下端面暴露于基座30的底面，便于与电源装置200中的电极柱抵接并导通。基座30的底面可沿纵向向上延伸形成有两个第二电极孔311以及两个穿孔313。两个第二电极43分别穿设于两个第二电极孔311中。电极连接件42的上端伸入到穿孔313中以与第一电极41连接并导通，电极连接件42的下端从穿孔313中穿出并弯折以与第二电极43连接并导通。基座30的底面还可凹陷形成有导向槽312，该导向槽312将第二电极孔311与穿孔313相连通，电极连接件42的下端弯折部分可从导向槽312中穿过，从而方便该弯折部分的安装固定。The electrode connector 42 may be a conductive metal sheet or a wire. The second electrode 43 may be a conductive column and is disposed in the base 30 in the longitudinal direction. The lower end surface of the second electrode 43 is exposed to the bottom surface of the base 30, so as to be in contact with and conduct with the electrode column in the power supply device 200. The bottom surface of the base 30 may extend upward in the longitudinal direction to form two second electrode holes 311 and two through holes 313. The two second electrodes 43 are respectively penetrated in the two second electrode holes 311. The upper end of the electrode connector 42 extends into the through hole 313 to connect and conduct with the first electrode 41, and the lower end of the electrode connector 42 passes through the through hole 313 and bends to connect and conduct with the second electrode 43. The bottom surface of the base 30 may also be recessed to form a guide groove 312, which connects the second electrode hole 311 with the through hole 313, and the lower end bent portion of the electrode connector 42 may pass through the guide groove 312, thereby facilitating the installation and fixation of the bent portion.
