[0046] The following will mainly describe the specific structure of the power supply device.

[0047] Reference Figures 1 to 7 In this embodiment of the invention, the power supply device includes:

[0048] The outer casing 100 is open at the bottom, and an installation cavity is formed inside the outer casing 100. The side wall of the outer casing 100 is provided with an movable hole that connects the outside and the installation cavity.

[0049] Mounting bracket 200 is installed in the mounting cavity;

[0050] The battery compartment 300 is movably inserted into the mounting cavity from the lower side of the outer shell 100 and is located on the lower side of the mounting bracket 200. A battery 310 is installed inside the battery compartment 300, and a snap hole 330 is provided on the outer wall of the battery compartment 300.

[0051] The movable block 500 is located in the mounting cavity and can be translated relative to the mounting bracket 200. The lower side of the movable block 500 is provided with a locking arm 510, and one side of the locking arm 510 is provided with a locking protrusion 520.

[0052] Button 400 is installed at one end of the movable block 500 and is movably inserted through the movable hole for the user to press;

[0053] A tension spring 600 is mounted at one end to the movable block 500 and at the other end to the mounting bracket 200, having both a natural state and an extended state. In the natural state, the spring 600 has a locking protrusion 520 engaged with the locking hole 330. When the button 400 is pressed, the button 400 moves the movable block 500, and the tension spring 600 is stretched to its extended state, at which point the locking protrusion 520 is released from its latching engagement with the locking hole 330.

[0054] Specifically, in this embodiment, when the battery compartment 300 is installed on the mounting bracket 200, the tension spring 600 is in its natural state. At this time, the latching protrusion 520 is engaged with the latching hole 330, that is, the latching protrusion 520 and the latching hole 330 are engaged to limit the battery compartment 300 to the mounting bracket 200. When the battery 310 needs to be replaced, press the button 400 to move the movable block 500, which in turn moves the locking arm 510 connected to the movable block 500. When the locking arm 510 moves to the point where the locking protrusion 520 disengages from the locking hole 330, the mounting bracket 200 releases its restriction on the battery compartment 300. At this point, the battery compartment 300 can be pulled out downwards, and then the new battery compartment 300 can be inserted into the mounting cavity at the angle of the locking hole 330 aligned with the locking protrusion 520. After insertion, release the button 400, and the tension spring 600 returns to its natural state. At the same time as the tension spring 600 returns to its natural state, it also moves the movable block 500 to its natural state, which in turn moves the locking protrusion 520 of the locking arm 510 to its natural state, locking it in the locking hole 330. This restricts the new battery compartment 300 within the mounting bracket 200, completing the assembly of the battery compartment 300.

[0055] In practical applications, to facilitate users' perception of whether the battery compartment 300 is inserted in place, a limiting step 340 is formed on the outer wall of the battery compartment 300. When the step surface of the limiting step 340 abuts against the lower end wall of the outer shell 100, the battery compartment 300 is inserted in place. Releasing the button 400 will enable the battery compartment 300 to be automatically installed and limited to the mounting bracket 200.

[0056] The technical solution of this invention involves setting a movable block 500, and using a tension spring 600 to reset the movable block 500. A button 400 is installed on the movable block 500 for user pressing. Pressing the button 400 moves the locking arm 510 on the movable block 500 until the locking protrusion 520 disengages from the locking hole 330, allowing the battery compartment 300 to be pulled out downwards. After inserting the new battery compartment 300 into the mounting cavity, releasing the button 400 resets the tension spring 600, causing the locking protrusion 520 on the locking arm 510 to reposition itself into the locking hole 330, thus securing the battery compartment 300 within the mounting bracket 200 and completing the battery compartment 300 replacement. This allows for easy removal of the battery compartment 300 without strenuous effort, improving the user experience. Furthermore, since the jack arm 510 only needs to move without deformation during the replacement of the battery compartment 300, it will not break, thus ensuring the installation stability of the battery compartment 300 and improving the reliability of the power supply device.

[0057] There are several options for the snap-fit ​​mechanism where the protrusion 520 is engaged with the hole 330, for example, referring to... Figure 4 In one embodiment, the latching arm 510 passes through the latching hole 330 and is movable along the length of the latching hole 330. The latching protrusion 520 is located on the side of the latching arm 510 facing the button 400. In its natural state, the latching arm 510 is close to or in contact with the end of the latching hole 330 near the button 400, and the latching protrusion 520 is located below the side of the latching hole 330 to engage with the outer wall of the latching hole 330. In its extended state, the latching arm 510 is close to or in contact with the end of the latching hole 330 away from the button 400, and the latching protrusion 520 is located directly below the latching hole 330. At this time, the latching protrusion 520 is released from its latching engagement with the latching hole 330, and the user can pull down the battery compartment 300 to remove it. (Refer to...) Figure 9 In another embodiment, the inner sidewall of the card hole 330 is provided with a card groove 331, which extends along the length direction of the card hole 330. In the natural state, the spring 600 has the card protrusion 520 inserted into the card groove 331. In the extended state, the spring 600 has the card protrusion 520 withdrawing from the card groove 331 to release the snap-fit ​​engagement with the card hole 330.

[0058] Furthermore, the latching arm 510 includes a connecting portion and a through portion in sequence along its extension direction. The connecting portion is connected to the movable block 500, and the through portion passes through the latching hole 330. The width of the connecting portion is greater than the width of the through portion, and the width of the connecting portion gradually decreases from the end connected to the movable block 500 towards the end connected to the through portion. Setting the width of the connecting portion to be larger results in a larger connection area between the latching arm 510 and the movable hole, thereby ensuring the strength of the latching arm 510 and allowing for a more stable engagement with the latching hole 330 of the battery compartment 300. This ensures that the battery compartment 300 is securely positioned within the mounting bracket 200, improving the installation stability of the battery compartment 300.

[0059] In some embodiments, the movable block 500 is located on the upper side of the mounting frame 200 and moves along its own length. The upper side of the mounting frame 200 is provided with a plurality of support blocks 210 and a limiting arm 220. The plurality of support blocks 210 are located below the movable block 500 to support the movable block 500. The plurality of limiting arms 220 are respectively disposed on both sides of the movable block 500 in the width direction. Each limiting arm 220 has a limiting protrusion 221 protruding on the side facing the movable block 500. The limiting protrusion 221 is located above the movable block 500 and is close to or in contact with the movable block 500. The mounting frame 200 is provided with a through hole 201, and the clamping arm 510 passes through the through hole 201. That is, in this embodiment, the support block 210 is used to support the movable block 500, and there are multiple support blocks 210, so that the movable block 500 is subjected to balanced forces and the stability of the movable block 500's translation is guaranteed. The setting of the limiting protrusion 221 can prevent the movable block 500 from shifting during translation and also prevent the movable block 500 from tilting upward, thereby ensuring that the movable block 500 moves along the preset path to reliably and stably drive the clamping arm 510 to move.

[0060] Furthermore, a stop 230 protrudes from the upper side of the mounting bracket 200, away from the button 400. When the tension spring 600 is extended, the end of the movable block 500 away from the button 400 contacts the stop 230. The end of the movable block 500 facing the button 400 includes a mounting portion with a mounting hole. The button 400 includes a pressing portion and a plug protruding from one side of the pressing portion. The plug is inserted into the mounting hole, and the pressing portion is for user pressing. Thus, when the user presses the button 400 and feels the movable block 500 being blocked by the stop 230, it indicates that the movable block 500 has moved into position. At this point, the latch 520 has released its engagement with the latch hole 330, allowing the battery compartment 300 to be removed for replacement. In other words, the stop 230 improves the efficiency of replacing the battery compartment 300, thereby enhancing the user's operating experience. To improve the stability of the button 400 installation, adhesive can be applied between the button 400 and the mounting part to bond the button 400 to the mounting part. Furthermore, the size of the mounting part is larger than the size of the pressing part and the movable hole, so that the movable block 500 is confined within the mounting cavity. In this way, the button 400 is also confined, preventing the button 400 from detaching from the outer casing 100.

[0061] In some embodiments, the movable block 500 has a receiving hole 540 extending through its upper and lower sides in the middle. The mounting bracket 200 has a first mounting post 240 near the button 400, which passes through the receiving hole 540. The wall of the receiving hole 540 has a connecting block connecting its opposite side walls. A second mounting post 530 is provided on the connecting block, located on the side of the first mounting post 240 away from the button 400. The two ends of the tension spring 600 are respectively sleeved on the first mounting post 240 and the second mounting post 530. This ensures the tension spring 600 is securely installed, improving its operational reliability. Furthermore, the tension spring 600 is also accommodated in the receiving hole 540, improving the overall compactness of the atomizing device.

[0062] In some embodiments, a main control circuit board 700 located above the mounting bracket 200 is also installed in the mounting cavity. A first electrical connection post 710 protrudes from the lower side of the main control circuit board 700. The mounting bracket 200 is provided with a first through hole for the first electrical connection post 710 to pass through. A connecting circuit board 320 connected to the battery 310 is also provided in the battery compartment 300. A second electrical connection post 321 protrudes from the upper side of the connecting circuit board 320. The compartment wall of the battery compartment 300 is provided with a second through hole for the second electrical connection post 321 to pass through. The second electrical connection post 321 contacts the first electrical connection post 710. In this embodiment, the battery 310 is connected to the main control circuit board 700 by setting the connecting circuit board 320, and the main control circuit board 700 and the connecting circuit board 320 are energized by the electrical connection post. This means that when replacing the battery compartment 300, there is no need to consider the connection between the battery 310 and the main control circuit board 700. The battery can be directly disassembled. After the new battery compartment 300 is installed, the second electrical connection post 321 of the new battery compartment 300 can automatically contact and energize with the first electrical connection post 710 of the main control circuit board 700, thereby finally realizing the energization between the battery 310 and the main control circuit board 700.

[0063] The present invention also proposes an installation method for a power supply device. A main control circuit board 700 located above a mounting bracket 200 is installed within the mounting cavity. A first electrical connection post 710 protrudes from the lower side of the main control circuit board 700. The mounting bracket 200 has a first through hole through which the first electrical connection post 710 passes. A connecting circuit board 320 connected to the battery 310 is also provided within the battery compartment 300. A second electrical connection post 321 protrudes from the upper side of the connecting circuit board 320. The compartment wall of the battery compartment 300 has a second through hole through which the second electrical connection post 321 passes. The second electrical connection post 321 contacts the first electrical connection post 710. The installation method for the power supply device includes the following steps:

[0064] S1: Install the movable block 500 onto the mounting bracket 200; (Specifically, push the movable block 500 downward from above the mounting bracket 200 with the locking arm 510 aligned with the through hole 201. During the pushing process, the movable block 500 presses down on the limiting arm 220, causing the limiting arm 220 to deform outward until the movable block 500 is pushed below the limiting protrusion 221, so that the movable block 500 is limited in the vertical direction by the limiting protrusion 221 and the support block 210.)

[0065] S2: Install the tension spring 600 onto the movable block 500 and the mounting bracket 200 to form a mounting assembly; (specifically, sleeve the two ends of the tension spring 600 onto the first mounting post 240 and the second mounting post 530 respectively.)

[0066] S3: Install the mounting assembly into the mounting cavity at an angle where the first through hole is aligned with the first electrical connection post 710, until the first electrical connection post 710 passes through the first through hole.

[0067] S4: Insert the button 400 through the outer side of the housing 100 into the movable hole, and continue to push the button 400 so that the button 400 is installed at one end of the movable block 500;

[0068] S5: Install the battery compartment 300 onto the mounting bracket 200.

[0069] The step of installing the battery compartment 300 onto the mounting bracket 200 includes:

[0070] S51: Press the button 400, bring the battery compartment 300 close to the mounting bracket 200, so that the protrusion at the lower part of the mounting bracket 200 enters the slot on the upper surface of the battery compartment 300, the locking arm 510 passes through the locking hole 330, the locking protrusion 520 is located directly below the locking hole 330, and the second electrical connection post 321 contacts the first electrical connection post 710;

[0071] S52: Keep the battery compartment 300 in position relative to the mounting bracket 200, release the button 400 until the latch 520 moves to the side and below the latch hole 330, and release the battery compartment 300.

[0072] That is, in this embodiment, the movable block 500 and the tension spring 600 are first installed on the mounting frame 200 to form a mounting assembly, then the mounting assembly is installed in the mounting cavity, and finally the battery compartment 300 is installed on the mounting frame 200.
