Description
Technical Field
[0001] This invention relates to the field of atomization technology, and in particular to a power supply device and a method for assembling the power supply device. Background Technology
[0002] The atomizing device includes an atomizing unit and a power supply unit for powering the atomizing unit. The atomizing unit internally comprises a liquid storage chamber, an atomizing chamber, and an atomizing core located within the atomizing chamber. The atomizing chamber and the liquid storage chamber are connected via a liquid inlet, allowing the atomizing core to absorb the oil from the liquid storage chamber. During use, the power supply unit powers the atomizing core, causing it to convert the absorbed oil into an aerosol for the user to inhale. In existing technology, to reduce leakage, a magnetic actuation component is installed within the liquid storage chamber, and an electromagnetic component is placed near the magnetic actuation component in the power supply unit. When the electromagnetic component is energized, the magnetic field generated by the electromagnetic and magnetic actuation components drives the magnetic actuation component to move, opening or closing the liquid inlet, thereby reducing the time the liquid inlet is open and minimizing leakage.
[0003] Since the distance between the electromagnetic component and the magnetic component directly affects the magnitude of the magnetic force, the stability of the electromagnetic component's installation is crucial to ensuring the stability of the magnetic force. However, in existing technologies, the installation stability of the electromagnetic component is poor due to an unreasonable installation design. Summary of the Invention
[0004] The main objective of this invention is to provide a power supply device that addresses the problem of poor installation stability of existing electromagnetic components, which leads to unstable magnetic force.
[0005] To achieve the above objectives, the power supply device proposed in this invention includes: A battery bracket has a battery cavity, and an installation groove is provided on the outer wall of the battery bracket. A wire through hole extending to communicate with the battery cavity is provided at the bottom of the installation groove. An electromagnetic component includes a mounting cover, an electromagnet, and a limiting sleeve. The mounting cover has a receiving groove, and the groove opening wall extends outward to form a limiting flange.

There is a movable gap between the limiting flange and the bottom wall of the mounting groove. The limiting sleeve is fitted onto the mounting cover, and the bottom wall of the limiting sleeve abuts against the limiting flange. The outer peripheral wall of the limiting sleeve abuts against the side wall of the mounting groove. The electromagnet is mounted in the receiving groove, and a first spring is provided between the electromagnet and the mounting groove. The lead wire of the electromagnet passes through the wire hole.
[0006] Optionally, a limiting post is provided at the bottom of the mounting groove, the lower part of the first spring is sleeved on the limiting post, the upper part of the first spring abuts against the lower surface of the electromagnet, and the lower part of the first spring abuts against the bottom wall of the mounting groove, so that the upper part of the electromagnet abuts against the bottom wall of the receiving groove.
[0007] Optionally, the bottom of the mounting groove is provided with a limiting protrusion, the limiting protrusion extends outward and connects to the side wall of the mounting groove, the limiting protrusion and the wire hole are on the same straight line, the limiting flange is provided with a clearance notch corresponding to the limiting protrusion, the clearance notch and the lead wire are on the same straight line, the limiting protrusion is slidably mounted on the clearance notch, the bottom wall of the limiting sleeve abuts against the upper surface of the limiting flange, and the bottom wall of the limiting sleeve abuts against the top wall of the limiting protrusion.
[0008] Optionally, the sidewall of the mounting groove includes a guide section near the groove opening. The radial dimension of the guide section gradually decreases from the groove opening towards the bottom of the groove, so as to form a guide slope on the wall surface of the guide section. The outer peripheral wall of the limiting sleeve forms multiple limiting protrusions extending circumferentially along the limiting sleeve. The multiple limiting protrusions are arranged along the height direction of the limiting sleeve. The limiting protrusions include a first part and a second part from bottom to top. The outer diameter of the first part gradually increases from bottom to top, while the outer diameter of the second part remains consistent from bottom to top.
[0009] The present invention also proposes a method for assembling a power supply device, comprising the following steps: S1: A battery holder and a first spring are provided. The battery holder has a battery cavity. The outer wall of the battery holder has a mounting groove. The bottom of the mounting groove has a through hole that extends to communicate with the battery cavity. One end of the first spring is installed at the bottom of the mounting groove. S2: Provide a mounting cover and a limiting sleeve, wherein the mounting cover has a receiving groove, and the groove wall of the receiving groove extends outward to form a limiting flange, and the limiting sleeve is fitted onto the mounting cover; S3: A mounting fixture is provided, the mounting fixture including a mounting component, a movable component, a second spring and a magnetic component, the mounting component forming a mounting cavity, the mounting cavity having an opening, the movable component being movably mounted in the mounting cavity, the movable component forming a limiting groove, the magnetic component being inserted into the limiting groove, the movable component having an insertion groove with its opening facing the opening, the second spring being located between the bottom of the mounting cavity and the movable component, and the end of the mounting cover away from its opening being inserted into the insertion groove; S4: Provide an electromagnet and install the electromagnet at the bottom of the receiving groove, so that the electromagnet is fixed to the bottom of the receiving groove under the attraction of the magnetic attractor. S5: Pass the lead wire of the electromagnet through the wire hole from top to bottom, press the mounting component down until the limiting flange abuts against the bottom of the mounting groove, the limiting sleeve is pressed against the bottom of the mounting component and inserted and fixed in the mounting groove, the movable part moves to the cavity opening away from the mounting cavity, and the first spring and the second spring are compressed. S6: Move the installation fixture so that the installation cover is removed from the cavity.
[0010] Optionally, the bottom of the mounting groove is provided with a limiting protrusion, the limiting protrusion is aligned with the wire hole, and the limiting flange is provided with a clearance notch corresponding to the limiting protrusion. Before the step of passing the electromagnet's lead wire through the wire hole from top to bottom, the following steps are included: S5-1: If the clearance notch and the lead wire are aligned in a straight line, align the clearance notch with the limiting protrusion. If the clearance notch and the lead wire are not aligned in a straight line, rotate the electromagnet until the clearance notch and the lead wire are aligned in a straight line, and then align the clearance notch with the limiting protrusion.
[0011] Optionally, the bottom of the mounting groove is provided with a limiting protrusion, and the limiting flange is provided with a clearance notch corresponding to the limiting protrusion. The step of passing the electromagnet's lead wire through the wire hole from top to bottom specifically includes: S5-01: Insert the lead wire of the electromagnet into the bottom of the mounting slot; S5-02: Rotate the mounting fixture until the lead wire of the electromagnet is exposed in the wire hole, and then press down the mounting fixture. If the limiting protrusion cannot enter the clearance notch, continue to rotate the mounting fixture until the limiting protrusion enters the clearance notch.
[0012] Optionally, in step S6, during the upward movement of the mounting fixture, the first spring resets and drives the mounting cover to move upward until the limiting flange abuts against the bottom wall of the limiting sleeve. The electromagnet is pushed to the bottom of the receiving groove by the first spring. The second spring resets and drives the movable member to reset. The movable member moves downward to abut against the cavity wall of the mounting cavity.
[0013] Optionally, the mounting cavity includes a first cavity segment and a second cavity segment in sequence in the direction away from the cavity opening. The radial dimension of the first cavity segment is smaller than that of the second cavity segment, so as to form a limiting step at the connection between the two. The outer wall of the movable member is provided with a locking protrusion that engages with the limiting step, so that after step S6, the mounting assembly limits the movable member to the mounting cavity.
[0014] Optionally, a limiting groove is provided on the side wall of the insertion slot, the limiting groove extending circumferentially along the insertion slot, and the mounting fixture further includes a silicone ring, the silicone ring being installed in the limiting groove and abutting against the outer peripheral wall of the mounting cover.
[0015] In the technical solution of this invention, the limiting sleeve and the limiting flange of the mounting cover abut against each other to limit the mounting cover and prevent it from detaching from the mounting groove. The first spring can fix the electromagnet relatively in the mounting groove of the mounting cover to ensure the stability of the electromagnet installation. On the other hand, because the first spring has elasticity, when the power supply device and the atomizing device are installed and cooperated, the force of the first spring can ensure that the power supply device and the atomizing device fit together properly, thereby ensuring that the electromagnet and the magnetic component always maintain a preset distance, thus ensuring the stability of the magnetic force.

[0021] The following will mainly describe the specific structure of the power supply device.
[0022] Reference Figures 1 to 7 In this embodiment of the invention, the power supply device includes: A battery bracket 100 has a battery cavity 110. The outer wall of the battery bracket 100 has a mounting groove 120. The bottom of the mounting groove 120 has a through hole 121 that extends to communicate with the battery cavity 110. The electromagnetic assembly includes a mounting cover 210, an electromagnet 220, and a limiting sleeve 230. The mounting cover 210 has a receiving groove 211, and the groove opening wall of the receiving groove 211 extends outward to form a limiting flange 212. The mounting cover 210 partially extends into the mounting groove 120, and the groove opening of the receiving groove 211 faces the bottom of the mounting groove 120. There is a movable gap between the limiting flange 212 and the bottom wall of the mounting groove 120. 214, the limiting sleeve 230 is fitted onto the mounting cover 210, the bottom wall of the limiting sleeve 230 abuts against the limiting flange 212, the outer peripheral wall of the limiting sleeve 230 abuts against the side wall of the mounting groove 120, the electromagnet 220 is installed in the receiving groove 211, a first spring 130 is also provided between the electromagnet 220 and the mounting groove 120, and the lead wire 221 of the electromagnet 220 passes through the wire hole 121.
[0023] In this embodiment, the limiting sleeve 230 abuts against the limiting flange 212 of the mounting cover 210 to limit the mounting cover 210 and prevent the mounting cover 210 from detaching from the mounting groove 120. The first spring 130 can fix the electromagnet 220 relatively in the mounting groove of the mounting cover 210 to ensure the stability of the electromagnet 220. On the other hand, since the first spring 130 has elasticity, when the power supply device and the atomizing device are installed and cooperated, the force of the first spring 130 can ensure that the power supply device and the atomizing device fit together, thereby ensuring that the electromagnet 220 and the magnetic component always maintain a preset distance, thereby ensuring the stability of the magnetic force.
[0024] In some embodiments, a limiting post 122 protrudes from the bottom of the mounting groove 120. The lower part of the first spring 130 is sleeved on the limiting post 122, the upper part of the first spring 130 abuts against the lower surface of the electromagnet 220, and the lower part of the first spring 130 abuts against the bottom wall of the mounting groove 120, so that the upper part of the electromagnet 220 abuts against the bottom wall of the receiving groove 211. The limiting post 122 can limit the first spring 130, preventing the first spring 130 from shifting or tilting, and ensuring the stability and reliability of the first spring 130. The first spring 130 is in a slightly compressed state, which ensures that the electromagnet 220 is clamped between the bottom wall of the receiving groove 211 and the first spring 130, ensuring the stability of the first spring 130, and also avoiding the problem of the first spring 130 easily failing due to long-term excessive compression.
[0025] To further limit the first spring 130, in some embodiments, the outer wall of the limiting post 122 is provided with limiting ribs 123 extending along the extending direction of the limiting post 122. The limiting ribs 123 contact the first spring 130, and there are multiple limiting ribs 123 arranged at intervals along the circumference of the limiting post 122. It can be understood that if the entire limiting post 122 is in contact with the first spring 130, the contact area is large, which may easily hinder the extension and retraction of the first spring 130. However, the setting of the limiting ribs 123 results in a smaller contact area with the first spring 130, which not only ensures that the first spring 130 is limited, but also minimizes the obstruction to the extension and retraction of the first spring 130, ensuring the smooth extension and retraction of the first spring 130.
[0026] In some embodiments, the bottom of the mounting groove 120 is provided with a limiting protrusion 124, the limiting protrusion 124 extends outward and connects to the side wall of the mounting groove 120, the limiting protrusion 124 and the wire hole 121 are located on the same straight line, the limiting flange 212 is provided with a clearance notch 213 corresponding to the limiting protrusion 124, the clearance notch 213 and the lead wire 221 are located on the same straight line, the limiting protrusion 124 is slidably mounted on the clearance notch 213, the bottom wall of the limiting sleeve 230 abuts against the upper surface of the limiting flange 212, and the bottom wall of the limiting sleeve 230 abuts against the top wall of the limiting protrusion 124. In this embodiment, "both are on the same straight line" means that their centers are on the same straight line. The limiting protrusion 124 and the clearance notch 213 are provided so that the battery bracket 100 can limit the mounting cover 210, preventing the mounting cover 210 from rotating arbitrarily and ensuring the relative stability of the electromagnetic component. It is worth mentioning that the limiting protrusion 124 can be adapted to fit into the clearance notch 213 to almost completely restrict the circumferential rotation of the mounting cover 210. Alternatively, the length of the clearance notch 213 can be slightly greater than the length of the limiting protrusion 124, so that the limiting protrusion 124 can enter the clearance notch 213 more smoothly, improving the ease of installation of the mounting cover 210. In this case, the mounting cover 210 can rotate slightly circumferentially, but it will not affect the distance between the electromagnet 220 and the magnetic component.
[0027] In some embodiments, the sidewall of the mounting groove 120 includes a guide section near the opening of the mounting groove 120. The radial dimension of the guide section gradually decreases from the opening of the mounting groove 120 toward the bottom of the groove, so as to form a guide slope 125 on the wall surface of the guide section. The outer peripheral wall of the limiting sleeve 230 is formed with multiple limiting protrusions 231 extending circumferentially along the limiting sleeve 230. The multiple limiting protrusions 231 are arranged along the height direction of the limiting sleeve 230. The limiting protrusions 231 include a first part and a second part from bottom to top. The outer diameter of the first part gradually increases from bottom to top, and the outer diameter of the second part remains the same from bottom to top. In this embodiment, the guide slope 125 guides the limiting sleeve 230 into the mounting groove 120, improving the smoothness of the installation of the limiting sleeve 230. The multiple limiting protrusions 231 of the limiting sleeve 230 can make the limiting sleeve 230 lock into the groove wall of the mounting groove 120, so that the limiting sleeve 230 is stably installed in the mounting groove 120, thereby limiting the mounting cover 210 and ensuring that the electromagnet 220 and the magnetic component always maintain a preset distance, thereby ensuring the stability of the magnetic force.
[0028] In some embodiments, the limiting sleeve 230 is interference-fitted with the mounting groove 120, and the top wall of the limiting sleeve 230 is flush with the groove opening wall of the mounting groove 120. The interference fit ensures that the limiting sleeve 230 is tightly inserted into the mounting groove 120, guaranteeing the stability of the entire electromagnetic assembly installation. The flushness of the top wall of the limiting sleeve 230 with the groove opening wall of the mounting groove 120 allows the limiting sleeve 230 to be housed within the mounting groove 120, preventing it from interfering with the installation of the power supply device and the atomizing device.
[0029] The present invention also proposes a method for assembling a power supply device, comprising the following steps: S1: A battery bracket 100 and a first spring 130 are provided. The battery bracket 100 forms a battery cavity 110. The outer wall of the battery bracket 100 is provided with a mounting groove 120. The bottom of the mounting groove 120 is provided with a wire hole 121 extending to communicate with the battery cavity 110. One end of the first spring 130 is installed at the bottom of the mounting groove 120. S2: A mounting cover 210 and a limiting sleeve 230 are provided. The mounting cover 210 has a receiving groove 211, and the groove wall of the receiving groove 211 extends outward to form a limiting flange 212. The limiting sleeve 230 is fitted onto the mounting cover 210. (At this time, under the action of gravity, the bottom wall of the limiting sleeve 230 abuts against the upper surface of the limiting flange 212, and the limiting flange 212 limits the limiting sleeve 230 so that it will not fall off the mounting cover 210.) S3: A mounting fixture 300 is provided, the mounting fixture 300 including a mounting assembly 310, a movable member 320, a second spring 330, and a magnetic suction member 340. The mounting assembly 310 forms a mounting cavity 311, the mounting cavity 311 having an opening. The movable member 320 is movably mounted in the mounting cavity 311, the movable member 320 forming a limiting groove 321, and the magnetic suction member 340 being inserted into the limiting groove 321. The movable member 320 is provided with an opening. The second spring 330 is located between the bottom of the mounting cavity 311 and the movable member 320, facing the insertion slot 322 of the cavity opening. The end of the mounting cover 210 away from its slot opening is inserted into the insertion slot 322. (After insertion, the mounting cover 210 together with the limiting sleeve 230 is fixed to the mounting fixture 300. The mounting cover 210 and the limiting sleeve 230 will not fall off the mounting fixture 300 without pulling them forcefully.) S4: Provide an electromagnet 220 and install the electromagnet 220 at the bottom of the receiving groove 211, so that the electromagnet 220 is fixed to the bottom of the receiving groove 211 under the attraction of the magnetic attractor 340; (specifically, the electromagnet 220 is placed into the receiving groove 211 and extends towards the bottom of the receiving groove 211. The electromagnet 220 will move to the bottom of the receiving groove 211 under the attraction of the magnetic attractor 340.) S5: Pass the lead wire 221 of the electromagnet 220 through the wire hole 121 from top to bottom, press the mounting assembly 310 downwards until the limiting flange 212 abuts against the bottom of the mounting groove 120, the limiting sleeve 230 is pressed against the bottom of the mounting assembly 310 and inserted and fixed in the mounting groove 120, the movable part 320 moves away from the cavity opening of the mounting cavity 311, and the first spring 130 and the second spring 330 are compressed; (After the limiting sleeve 230 is pressed into the mounting groove 120 by the mounting assembly 310, the upper end wall of the limiting sleeve 230 is flush with the groove opening wall of the mounting groove 120, and there is a certain distance between the lower end wall and the limiting flange 212. At this time, the limiting sleeve 230 is installed in place, and the mounting cover 210 extends into the bottom of the mounting groove 120 under the action of the pressing assembly, and drives the first spring 130 to move and be compressed) S6: Move the installation fixture 300 so that the installation cover 210 is removed from the cavity. (During the removal of the installation fixture 300, the first spring 130 gradually resets and drives the installation cover 210 to move upward until the limiting flange 212 abuts against the bottom wall of the limiting sleeve 230. The electromagnet 220 is pushed to the bottom of the receiving groove 211 by the first spring 130. At this time, the limiting sleeve 230 and the electromagnet 220 are also installed in place. At the same time, the second spring 330 resets and drives the movable part 320 to reset. The movable part 320 moves downward to abut against the cavity wall of the installation cavity 311.) In some embodiments, the bottom of the mounting groove 120 is provided with a limiting protrusion 124, the limiting protrusion 124 and the wire hole 121 are located on the same straight line, and the limiting flange 212 is provided with a clearance notch 213 corresponding to the limiting protrusion 124. Before the step of passing the lead wire 221 of the electromagnet 220 through the wire hole 121 from top to bottom, the following steps are included: S5-1: If the clearance notch 213 and the lead wire 221 are aligned in a straight line, align the clearance notch 213 with the limiting protrusion 124. If the clearance notch 213 and the lead wire 221 are not aligned in a straight line, rotate the electromagnet 220 until the clearance notch 213 and the lead wire 221 are aligned in a straight line, and then align the clearance notch 213 with the limiting protrusion 124.
[0030] Specifically, in this embodiment, "the two are on the same straight line" means that the centers of the two are on the same straight line. The avoidance notch 213 and the limiting protrusion 124 are set to facilitate the operator to judge the installation direction of the electromagnetic component, so as to improve the installation convenience of the electromagnetic component.
[0031] In some embodiments, the bottom of the mounting groove 120 is provided with a limiting protrusion 124, and the limiting flange 212 is provided with a clearance notch 213 corresponding to the limiting protrusion 124. The step of passing the lead wire 221 of the electromagnet 220 through the wire hole 121 from top to bottom specifically includes: S5-01: Insert the lead wire 221 of the electromagnet 220 into the bottom of the mounting slot 120; S5-02: Rotate the mounting fixture 300 until the lead wire 221 of the electromagnet 220 is exposed in the wire hole 121, and then press down the mounting fixture 300. If the limiting protrusion 124 cannot enter the clearance notch 213, continue to rotate the mounting fixture 300 until the limiting protrusion 124 enters the clearance notch 213.
[0032] That is, the operator can choose not to visually inspect whether the lead wire 221 is aligned with the wire hole 121. After rotating the installation fixture 300 until the lead wire 221 enters the wire hole 121, the operator can press down on the installation fixture 300. When the operator feels that they cannot press down any further, it means that the limiting protrusion 124 is not aligned with the clearance notch 213 and therefore cannot enter the clearance notch 213. The operator can then continue to rotate the installation fixture 300 until the limiting protrusion 124 enters the clearance notch 213 and then proceed to the next step.
[0033] In some embodiments, the mounting cavity 311 sequentially includes a first cavity segment and a second cavity segment in a direction away from the cavity opening. The radial dimension of the first cavity segment is smaller than that of the second cavity segment, so as to form a limiting step 312 at the connection between the two. The outer wall of the movable member 320 is provided with a locking protrusion 323 that engages with the limiting step 312, so that after step S6, the mounting assembly 310 limits the movable member 320 to the mounting cavity 311. In this way, the movable member 320 is prevented from falling out of the mounting cavity 311, thereby ensuring the integrity of the mounting fixture 300 and the reliability of the use of the mounting fixture 300.
[0034] In some embodiments, a limiting groove is formed on the side wall of the insertion slot 322, the limiting groove extending circumferentially along the insertion slot 322. The mounting fixture 300 further includes a silicone ring 350, which is installed in the limiting groove and abuts against the outer peripheral wall of the mounting cover 210. The silicone ring 350 generates friction with the mounting cover 210, so that during the installation of the electromagnetic component, the mounting cover 210 can be relatively securely inserted into the insertion slot 322 and is not easily dislodged from the mounting fixture 300, thereby facilitating subsequent operations. After the electromagnetic component is installed, the mounting fixture 300 is moved slightly to overcome the friction between the silicone ring 350 and the mounting cover 210, so that the mounting cover 210 can be removed from the insertion slot 322 under the action of external force.
[0035] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
