The power supply device comprises a main body 1, a contact component 2, a first sealing element 4 and a power supply component 3 with a lead 31, wherein the main body 1 is provided with an accommodating groove 13 for accommodating an external load and a battery bin 14 for accommodating the power supply component 3, the accommodating groove 13 and the battery bin 14 are adjacently arranged and are communicated only through a wire passing hole 121, the contact component 2 is installed in the accommodating groove 13 for electrically connecting the external load, the power supply component 3 is accommodated in the battery bin 14, the lead 31 passes through the wire passing hole 121 and is electrically connected with the contact component 2, and the first sealing element 4 blocks a gap between the lead 31 and the wire passing hole 121 so as to completely isolate the accommodating groove 13 and the battery bin 14. In the embodiment, the contact assembly 2 is completely installed in the accommodating groove 13, and the first sealing member 4 is used for sealing the wire passing hole 121 through which the wire 31 passes, so that static sealing between the accommodating groove 13 and the battery compartment 14 is realized, the reliability of the sealing structure is improved, and oil in the accommodating groove 13 is prevented from permeating into the battery compartment 14.
In the present embodiment, as shown in fig. 1 to 4, the main body 1 includes a frame 11 and a partition 12, the frame 11 has a hollow structure, and the frame 11 is erected in the frame 11 and divides the frame 11 into a storage groove 13 and a battery compartment 14. The accommodating groove 13 includes a bottom wall and four side walls, the bottom wall is the partition plate 12, the four side walls are each side wall of the frame body 11, and the four side walls are sequentially connected and vertically connected to the bottom wall to form the accommodating groove 13. Since the housing groove 13 is used to house an external load such as an atomizer, the soot stored in the atomizer or the condensate formed by atomization may leak out and flow into the housing groove 13. In order to prevent the oil from flowing into the battery compartment 14 from the housing groove 13, there is no gap between the bottom wall of the housing groove 13 and the four side walls, that is, no gap between the partition plate 12 and the connecting portion of each side wall of the frame 11. Preferably, the partition plate 12 and the frame body 11 are integrally formed, so that the reliability and compactness of the joint of the partition plate and the frame body are easily ensured, and the problem of other connecting gaps in connecting modes such as screw connection, riveting and clamping is avoided.
In the present embodiment, as shown in fig. 2-3 and 5, the contact assembly 2 includes a holder 21, a first contact member 22, and a second contact member 23. The support 21 may be a square, a cylinder, a polygon or other irregular structure. In this embodiment, the support 21 is a square structure, and includes a top end 211, a bottom end 212, and a side surface 213, where the top end 211 and the bottom end 212 face away from each other, and the side surface 213 is connected to the top end 211 and the bottom end 212, respectively. The bottom end 212 is provided with at least one positioning hole 214 and two slots. Correspondingly, the partition board 12 is provided with at least one positioning column 122 in the accommodating groove 13, the positioning column 122 is matched with the positioning hole 214, and the support 21 is mounted on the partition board 12 (the bottom wall of the accommodating groove 13) through the matching between the positioning hole 214 and the positioning column 122. The at least one positioning hole 214 may be one, two, or more, and each positioning hole 214 is uniformly distributed on one side of the support 21 facing the partition 12, so that each part of the support 21 may obtain a uniform fastening force. For example, when the support 21 has a square structure, two positioning holes 214 may be provided, and the two positioning holes 214 are distributed at two opposite corners; four positioning holes 214 may also be provided, and the four positioning holes 214 are distributed at four corners of the support 21. In practical applications, the number and the positions of the positioning holes 214 can be set according to the shape of the support 21, which is not described herein. Preferably, the positioning post 122 is in interference fit with the positioning hole 214, so as to perform the positioning function and also perform the fastening function, and prevent the support 21 from shaking.
Further, the bottom wall of the receiving groove 13 (i.e. the partition 12) is provided with a groove 123, and the size of the groove 123 is matched with the size of the support 21, so that the support 21 can be completely received in the groove 123. Correspondingly, the at least one positioning column 122 is convexly arranged on the bottom wall of the groove 123. When the holder 21 is fastened in said recess 123, the displacement of the holder 21 in the horizontal direction may also be limited by the side walls of the recess 123. On the other hand, since the holder 21 is entirely received in the recess 123, when the external load is received in the receiving groove 13, the liquid oozed from the external load first flows into the recess 123, and the liquid is prevented from flowing to other portions of the receiving groove 13 by the recess 123.
The two slots have the same structure and are U-shaped slots, each slot includes a closed end 205 and an open end 204, the closed end 205 is located in the end face of the bottom end 212, and the open end 204 extends from the end face of the bottom end 212 to the side face to form a channel for the contact assembly 2 to extend out of the support 21. When the seat 21 is fastened to the partition 12, the inner wall of the slot and the partition 12 enclose a first mounting cavity 24 and a second mounting cavity 25. Further, the two slots are arranged independently of each other and respectively marked as a first slot 215 and a second slot 216, so that when the support 21 is fastened to the partition 12, the first slot 215 and the second slot 216, which are independent of each other, respectively enclose a first mounting cavity 24 and a second mounting cavity 25, which are independent of each other, with the partition 12, so that when the subsequent first contact member 22 and the subsequent second contact member 23 are respectively mounted in the corresponding mounting cavities, the problem of short circuit caused by mutual contact can be avoided.
In the present embodiment, the first contact member 22 is used for electrically connecting with the positive electrode of the power supply component 3, and the second contact member 23 is used for electrically connecting with the negative electrode of the power supply component 3. Namely, the leads 31 are respectively led out from the positive pole and the negative pole of the power supply component 3, and the first contact member 22 and the second contact member 23 are respectively electrically connected with the corresponding leads 31. The first contact member 22 and the second contact member 23 are identical in structure and each include a contact column 201, a wiring board 203 and an elastic member 202. The contact column 201 vertically passes through the top end 211 of the support 21, and has one end received in the support 21 (i.e. in the corresponding mounting cavity) and the other end extending out of the support 21 from the top end 211 for electrical contact with an external load.
One end of the elastic element 202 is connected to one end of the contact column 201 accommodated in the support 21, and the other end of the elastic element is elastically abutted to the partition plate 12, and the elastic element 202 may be sleeved on the periphery of the contact column 201 or an accommodating space for accommodating the elastic element 202 may be provided in the contact column 201 along the axial direction. In practical applications, the elastic member 202 may be a spring, a leaf spring, or other elastic structure. When the seat 21 is fastened to the separator 12, the elastic member 202 is compressed by the contact column 201, and is in a pre-compressed state; when the atomization device is installed in the accommodating groove 13, the anode contact and the cathode contact of the atomization device are respectively in contact with the corresponding contact posts 201, and the contact posts 201 are pressed, the contact posts 201 move downwards, and the elastic member 202 is continuously compressed, so that the atomization device is elastically abutted against the two contact posts 201, and stable electric contact is formed. Preferably, the exposed surface of the contact column 201 is in a rounded arc structure, which facilitates the contact column 201 to make smooth contact with the atomization device.
The wiring board 203 includes a limiting portion 2031, a guiding portion 2032, and a wiring portion 2033, wherein the limiting portion 2031 is vertically connected to the guiding portion 2032, and the guiding portion 2032 is vertically connected to the wiring portion 2033, so that the wiring board 203 has a zigzag structure. The position limiting portion 2031 is provided with a through hole (not shown) through which the contact post 201 is sleeved. The position limiting portion 2031 is located above the elastic member 202, when the contact post 201 is not pressed by an external load, because the elastic member 202 is in a pre-pressing state and applies an upward force to the contact post 201, the contact post 201 has a tendency of moving upward, and the position limiting portion 2031 also has a tendency of moving upward under the driving of the contact post 201, so that the position limiting portion 2031 is pressed upward toward the inner wall of the slot and abuts against the inner wall of the slot. Since the position-limiting portion 2031 is fastened to the contact post 201, the position-limiting portion 2031 can limit the upward movement of the contact post 201, and prevent the contact post 201 from being ejected out of the support 21 by the elastic member 202.
Further, the guiding portion 2032 is accommodated in the slot, and forms a space for accommodating the elastic member 202 with the slot. Preferably, the guiding portion 2032 is an arc-shaped plate, and the slot is disposed in an arc-shaped slot of the arc-shaped plate in mirror symmetry. The radian of arc and the external diameter looks adaptation of spring to the spring holding can fix a position the spring through arc and arc when the fluting, plays the effect of direction simultaneously, avoids the spring to take place great swing at flexible in-process, thereby influences the stability of contact post 201 and external load electrical contact, causes contact failure's problem.
One end of the wiring board 203 is connected to the guide portion 2032 and extends out of the support 21 from the open end 204 of the slot for soldering the wire 31. Since the wiring board 203 of the first contact assembly 2 and the wiring board 203 of the second contact assembly 2 extend out of the support 21 from the corresponding slots, and both the wiring boards 203 can move up and down under the action of the corresponding elastic members 202, the problem of short circuit caused by mutual contact of the two wiring boards 203 in the process of moving up and down is solved. A first extension of the first slot 215 extending from the closed end 205 to the open end 204 does not intersect a second extension of the second slot 216 extending from the closed end 205 to the open end 204. Preferably, the open end 204 of the first slot 215 and the open end 204 of the second slot 216 are arranged away from each other, which allows the two terminal plates 203 to project from the support 21 completely from opposite directions, thereby avoiding the possibility of contact between the two terminal plates 203 and facilitating subsequent soldering of the wires 31 and the wire management.
In this embodiment, two wires 31 are led out from the power supply module 3, one end of each of the two wires 31 is electrically connected to the positive electrode and the negative electrode of the power supply module 3, and the other end of each of the two wires 31 passes through the wire passing hole 121 and extends into the accommodating groove 13. One of the wires 31 is soldered to the wiring board 203 of the first contact assembly 2 and the other wire 31 is soldered to the wiring board 203 of the second contact assembly 2. Thus, the assembly of the power supply line of the power supply device is completed. Since the receiving groove 13 and the battery compartment 14 are only communicated through the wire through hole 121, the first sealing member 4 is disposed in the wire through hole 121 to seal the two wires 31 and the wire through hole 121 and the gap between the two wires 31, so that the receiving groove 13 and the battery compartment 14 can be completely isolated. In practical applications, the first sealing element 4 may be made of a material such as silicone rubber, electronic silicone rubber, or sealing glue.
Further, the length of the two wires 31 extending out of the accommodating groove 13 is greater than the distance between the corresponding wiring board 203 and the wire passing hole 121. That is, when the two wires 31 are connected to the corresponding terminal plates 203, respectively, they are not stretched and are in a natural state or have a margin in length. Thus, when the external load presses the contact column 201 to drive the wiring board 203 to move, since the material of the wire 31 itself is soft, the wire 31 only moves from the end welded to the wiring board 203, and does not drive the portion of the wire 31 sealed at the wire passing hole 121 to move. Therefore, the first sealing element 4 can form static sealing when the two leads 31, the wire through hole 121 and the gap between the two leads 31 are sealed, so that the sealing state is stable and reliable, and the sealing effect is greatly improved.
In this embodiment, referring to fig. 2-3 and fig. 5-6, the power supply device further includes a second sealing member 5, which includes a hard glue portion 51 and a soft glue portion 52. The hard rubber part 51 is made of hard rubber material, such as plastic, engineering plastic stool. The soft rubber portion 52 is made of soft rubber material, such as rubber, silica gel, etc. The soft adhesive part 52 and the hard adhesive part 51 are sequentially accommodated in the accommodating groove 13 from bottom to top. The hard rubber part 51 is a sheet-shaped or plate-shaped structure matched with the accommodating groove 13, and when the hard rubber part 51 is placed in the accommodating groove 13, the side edge of the hard rubber part is attached to the side wall of the accommodating groove 13. In practical application, a plurality of connecting holes are uniformly formed on the hard rubber part 51, corresponding connecting holes are formed on the partition plate 12, and the hard rubber part 51 is fastened on the partition plate 12 by sequentially passing through the connecting holes on the hard rubber part 51 and the partition plate 12 through the connecting piece 6. Since the soft rubber portion 52 has elasticity and high plasticity, the soft rubber portion 52 can be pressed into the receiving groove 13 through the hard rubber portion 51, so that the soft rubber portion 52 is elastically abutted to the partition 12 (the bottom wall of the receiving groove 13) and the four side walls of the receiving groove 13, respectively, and the second sealing member 5 and the receiving groove 13 form a sealing cavity 7. The part of the lead wire 31 extending out of the battery compartment 14, the first sealing member 4 and the wire through hole 121 are all accommodated in the sealing cavity 7. In this way, the liquid flowing out from the external load is blocked outside the sealing cavity 7 by the second sealing element 5, so that a layer of sealing is added on the static sealing layer formed by the first sealing element 4, and the sealing performance of the power supply device is further improved.
Further, the soft rubber part 52 includes a first soft rubber part 521 and a second soft rubber part 522. The first soft rubber portion 521 covers the contact assembly 2, that is, the first soft rubber portion 521 covers the top end 211 of the support 21. Since the two contact posts 201 of the contact assembly 2 extend out of the support 21, the first soft rubber portion 521 is provided with two avoiding holes adapted to the two contact posts 201. Two keep away the position hole interval and set up, and with the interference fit of corresponding contact post 201, can prevent like this that fluid from the periphery of contact post 201 and the clearance between support 21 in flowing into support 21 to the elastic component 202 and the contact post 201 that hold in the corruption support 21 influence electric conductive property.
Further, as shown in fig. 7, since the contact pillar 201 moves up and down under the pressure of the external load, the sealing performance is not affected by the displacement between the contact pillar 201 and the hole wall of the corresponding clearance hole. The two contact columns 201 are respectively provided with a recessed portion (not marked in the figure) along the circumferential direction, and the two avoiding holes are respectively provided with a matched flange. When the first soft rubber part 521 is covered on the contact assembly 2, the flange is accommodated in the recessed part and elastically abuts against the recessed part. In this embodiment, the recess and the flange are engaged to limit the relative displacement between the contact column 201 and the corresponding clearance hole, so as to prevent the first soft rubber portion 521 from failing in sealing.
In this embodiment, the second soft rubber portion 522 is a ring structure, and the size and shape of the outer ring thereof are matched with the size and shape of the accommodating groove 13.
