Description
Technical Field
[0001] This utility model relates to the field of atomization technology, and in particular to a power supply device and an atomization device. Background Technology
[0002] Atomizing devices typically include an atomizing unit and a power supply unit. The power supply unit powers the atomizing coil inside the atomizing unit, causing it to heat up and produce atomized vapor for the user to inhale. The power supply unit usually includes a housing and a mounting bracket inside the housing. The mounting bracket is used to mount the circuit board, battery, etc. To prevent the atomizing fluid from dripping onto the circuit board and battery, a seal is usually installed on the mounting bracket. The outer wall of the seal abuts against the inner wall of the housing, dividing the interior of the housing into upper and lower chambers. The atomizing coil is located in the upper chamber, and the circuit board and battery are located in the lower chamber.
[0003] However, existing seals suffer from insufficient strength due to inadequate structural design. After being installed in the housing, they are prone to deformation, resulting in poor sealing. This can lead to gaps between the seal and the housing, allowing the atomizing coil's oil to easily flow into the lower chamber, inevitably causing oil corrosion of the battery and circuit board. Therefore, a higher-strength seal is needed to improve its sealing performance. Utility Model Content
[0004] The main purpose of this utility model is to provide a power supply device that aims to solve the problem that the existing sealing parts are not strong enough and are prone to deformation after being installed in the housing, resulting in poor tightness between them and the housing.
[0005] To achieve the above objectives, the power supply device proposed in this utility model includes:
[0006] The housing assembly has an internal mounting cavity;
[0007] A sealing element is inserted into the mounting cavity. The sealing element includes a sealing ring and a connecting block disposed at the upper end of the sealing ring. The peripheral wall of the connecting block is connected to the inner peripheral wall of the sealing ring so that the sealing element as a whole is a cover shape with the lower end open. The outer peripheral wall of the sealing ring abuts against the peripheral wall of the mounting cavity. The middle part of the connecting block protrudes downward to form a mounting protrusion. A mounting gap is formed between the peripheral wall of the mounting protrusion and the inner peripheral wall of the sealing ring. A reinforcing rib is provided at the mounting gap, with its two ends respectively connecting the sealing ring and the mounting protrusion. The number of reinforcing ribs is at least two, and the at least two reinforcing ribs are arranged along the circumference of the sealing ring.
[0008] The mounting bracket is installed on the housing assembly. The lower end of the mounting bracket seals the opening of the mounting cavity. A battery is installed in the middle. A plug-in ring protrudes from the upper end. The plug-in ring is inserted into the mounting gap. The plug-in ring has a clearance groove corresponding to the position of the reinforcing rib. The reinforcing rib is inserted into the clearance groove.
[0009] Optionally, the number of reinforcing ribs is four, with two reinforcing ribs located on both sides of the first diameter direction of the sealing ring and the other two reinforcing ribs located on both sides of the second diameter direction of the sealing ring, the first diameter direction and the second diameter direction forming an angle.
[0010] Optionally, the upper side of the reinforcing rib is connected to the lower side of the connecting block.
[0011] Optionally, the reinforcing rib is integrally formed with the sealing ring and the connecting block.
[0012] Optionally, the width of the clearance groove gradually increases from the bottom of the groove towards the opening; and / or, the opening wall of the clearance groove is set as a convex arc surface to form an arc-shaped chamfer at the opening wall of the clearance groove.
[0013] Optionally, the sealing ring includes a first part and a second part from top to bottom. The inner diameter of the first part is larger than the inner diameter of the second part, so as to form a limiting groove between the lower side of the connecting block and the inner wall of the first part and the inner wall of the second part. The interior of the limiting groove constitutes a part of the installation gap. The reinforcing rib is connected to the bottom of the limiting groove. The upper end of the insertion ring extends outward to form a limiting protrusion. The limiting protrusion is inserted into the limiting groove to limit the sealing element to the mounting bracket.
[0014] Optionally, the upper end of the mounting bracket is provided with an abutment platform, the abutment platform has a protruding insertion ring on its surface, and the lower end wall of the sealing ring abuts against the surface of the abutment platform.
[0015] Optionally, the outer peripheral wall of the sealing ring is formed with at least two sealing protrusions, which are arranged along the height direction of the sealing ring and abut against the cavity wall of the mounting cavity.
[0016] Optionally, the number of sealing rings is three, including a first sealing ring, a second sealing ring and a third sealing ring from top to bottom. The first sealing ring is disposed near the upper side of the reinforcing rib, the second sealing ring is disposed near the lower side of the reinforcing rib, and the third sealing ring is disposed near the lower end of the sealing ring.
[0017] This utility model also proposes an atomizing device, including an atomizing apparatus and the aforementioned power supply device, wherein the power supply device is used to provide electrical energy to the atomizing apparatus.
[0018] The technical solution of this utility model features reinforcing ribs between the sealing ring and the mounting protrusion. These ribs and the mounting protrusion provide support to the sealing ring, increasing its strength. Consequently, during the installation process, the sealing ring is less prone to folding or buckling, ensuring structural stability. After the seal and mounting bracket are in place, the outer circumferential wall of the sealing ring tightly abuts against the circumferential wall of the mounting cavity, improving the sealing effect. Furthermore, the reinforcing ribs and clearance grooves further limit the mutual positioning of the seal and mounting bracket, preventing rotation and facilitating user observation of the installation angle, thus improving the ease of installation.

[0032] The following will mainly describe the specific structure of the power supply device.
[0033] Reference Figures 1 to 5 In this embodiment of the utility model, the power supply device includes:
[0034] The housing assembly 100 has an internal mounting cavity 101;
[0035] A sealing element 200 is inserted into the mounting cavity 101. The sealing element 200 includes a sealing ring 210 and a connecting block 220 disposed on the upper end of the sealing ring 210. The peripheral wall of the connecting block 220 is connected to the inner peripheral wall of the sealing ring 210, so that the sealing element 200 is generally open at the lower end. The outer peripheral wall of the sealing ring 210 abuts against the peripheral wall of the mounting cavity 101. The middle part of the connecting block 220 protrudes downward to form a mounting protrusion 221. A mounting gap 201 is formed between the peripheral wall of the mounting protrusion 221 and the inner peripheral wall of the sealing ring 210. A reinforcing rib 230 is provided at the mounting gap 201, with its two ends respectively connecting the sealing ring 210 and the mounting protrusion 221. The number of reinforcing ribs 230 is at least two, and at least two reinforcing ribs 230 are arranged along the circumference of the sealing ring 210.
[0036] Mounting bracket 300 is installed on the housing assembly 100. The lower end of the mounting bracket 300 seals the opening of the mounting cavity 101. A battery 400 is installed in the middle. A plug-in ring 320 is protruding from the upper end. The plug-in ring 320 is inserted into the mounting gap 201. The plug-in ring 320 has a relief groove 321 corresponding to the position of the reinforcing rib 230. The reinforcing rib 230 is inserted into the relief groove 321.
[0037] Specifically, in this embodiment, the housing assembly 100 can be composed of an outer shell 110 and an inner tube 120, with the outer shell 110 fitted over the inner tube 120. When assembling the atomizing device, the sealing element 200 is first installed on the mounting bracket 300 with the reinforcing rib 230 aligned with the clearance groove 321. At this time, the insertion ring 320 is inserted into the mounting gap 201, and the reinforcing rib 230 is inserted into the clearance groove 321, thus limiting the sealing element 200 and the mounting bracket 300 to prevent relative offset and rotation. Then, the sealing element 200 and the mounting bracket 300 are inserted together from the bottom of the housing assembly 100 into the mounting cavity 101.
[0038] The technical solution of this utility model, due to the reinforcing rib 230 between the sealing ring 210 and the mounting protrusion 221, allows the sealing ring 210 to be supported by the reinforcing rib 230 and the mounting protrusion 221, thus improving the strength of the sealing ring 210. Therefore, during the process of the sealing element 200 being inserted into the mounting cavity 101 and abutting against the cavity wall of the mounting cavity 101, the sealing ring 210 is less likely to fold or buckle, ensuring the structural stability of the sealing element 200. Thus, after the sealing element 200 and the mounting bracket 300 are installed in place, the outer peripheral wall of the sealing ring 210 abuts tightly against the peripheral wall of the mounting cavity 101, thereby improving the sealing effect of the sealing element 200. Furthermore, the setting of the reinforcing rib 230 and the clearance groove 321 further limits the mutual positioning of the sealing element 200 and the mounting bracket 300, preventing rotation between them, and also facilitates the user's observation of the installation angle, thereby improving the convenience of installing the sealing element 200 onto the mounting bracket 300.
[0039] The number of reinforcing ribs 230 can be three, four, five, or other numbers. In some embodiments, the number of reinforcing ribs 230 is four, with two reinforcing ribs 230 respectively disposed on both sides of the first diameter direction of the sealing ring 210, and the other two reinforcing ribs 230 respectively disposed on both sides of the second diameter direction of the sealing ring 210, the first diameter direction and the second diameter direction forming an angle. In this way, the sealing ring 210 is subjected to balanced forces during the process of the sealing member 200 being inserted into the mounting cavity 101 and abutting against the cavity wall of the mounting cavity 101, thereby further ensuring that the sealing ring 210 is not prone to folding or bending, ensuring the structural stability of the sealing member 200, and ensuring that after the sealing member 200 is installed in place, the outer peripheral wall of the sealing ring 210 abuts tightly against the peripheral wall of the mounting cavity 101, further improving the sealing effect of the sealing member 200.
[0040] In some embodiments, the upper side of the reinforcing rib 230 is connected to the lower side of the connecting block 220. It is understood that, compared to the reinforcing rib 230 being suspended between the sealing ring 210 and the mounting protrusion 221, the connection of the upper side of the reinforcing rib 230 to the lower side of the connecting block 220 allows the reinforcing rib 230 to be supported by the connecting block 220. This increases the strength of the reinforcing rib 230, thereby indirectly increasing the strength of the sealing ring 210, thus improving the reliability of the seal 200 and its sealing effect. There are many other ways to increase the strength of the sealing ring 210. For example, in other embodiments, the reinforcing rib 230 is integrally formed with the sealing ring 210 and the connecting block 220. This allows the various parts of the seal 200 to support each other, making the overall structure of the seal 200 more robust, thereby improving the reliability of the seal 200 and its sealing effect.
[0041] In some embodiments, the width of the clearance groove 321 gradually increases from the bottom of the groove towards the opening. This makes the clearance groove 321 wider at the top and narrower at the bottom, facilitating the insertion of the reinforcing rib 230 into the clearance groove 321, thereby improving the ease of installing the seal 200 onto the mounting bracket 300. In some embodiments, the opening wall of the clearance groove 321 is provided as a convex arc surface, forming an arc-shaped chamfer 322 at the opening wall of the clearance groove 321. Compared to a straight chamfer, the surface of the arc-shaped chamfer 322 is smoother, thus reducing the obstruction of the groove wall of the clearance groove 321 to the reinforcing rib 230, facilitating the insertion of the reinforcing rib 230 into the clearance groove 321, thereby improving the ease of installing the seal 200 onto the mounting bracket 300.
[0042] In some embodiments, the sealing ring 210 comprises a first part and a second part from top to bottom. The inner diameter of the first part is larger than the inner diameter of the second part, forming a limiting groove 202 between the lower side of the connecting block 220 and the inner walls of the first and second parts. The interior of the limiting groove 202 constitutes a portion of the mounting gap 201. The reinforcing rib 230 is connected to the bottom of the limiting groove 202. The upper end of the insertion ring 320 extends outward to form a limiting protrusion 323, which is inserted into the limiting groove 202 to limit the sealing member 200 within the mounting bracket 300. This prevents the sealing member 200 from moving up and down relative to the mounting bracket 300, ensuring the stability of the sealing member 200 installation and thus improving the sealing effect of the sealing member 200. There are many other ways to improve the stability of the seal 200 mounted on the mounting bracket 300. For example, in some embodiments, the upper end of the mounting bracket 300 is provided with an abutment platform 310, and the insertion ring 320 protrudes from the platform surface of the abutment platform 310. The lower end wall of the sealing ring 210 abuts against the platform surface of the abutment platform 310. In this way, the seal 200 is supported by the mounting bracket 300, improving the installation reliability and stability of the seal 200, thereby improving the sealing effect of the seal 200.
[0043] In some embodiments, at least two sealing protrusions are formed on the outer peripheral wall of the sealing ring 210. The at least two sealing protrusions are arranged along the height direction of the sealing ring 210, and the sealing protrusions abut against the cavity wall of the mounting cavity 101. Specifically, there are three sealing protrusions, which are arranged from top to bottom as a first sealing protrusion 211, a second sealing protrusion 212, and a third sealing protrusion 213. The first sealing protrusion 211 is disposed near the upper side of the reinforcing rib 230, the second sealing protrusion 212 is disposed near the lower side of the reinforcing rib 230, and the third sealing protrusion 213 is disposed near the lower end of the sealing ring 210. That is, in this embodiment, the first sealing ring 211 and the second sealing ring 212 correspond to the upper and lower sides of the reinforcing rib 230, so that the reinforcing rib 230 can support the first sealing ring 211 and the second sealing ring 212, improve the strength of the first sealing ring 211 and the second sealing ring 212, thereby improving the tightness of the first sealing ring 211 and the second sealing ring 212 against the cavity wall of the mounting cavity 101, and ultimately improving the sealing effect of the first sealing ring 211 and the second sealing ring 212. The setting of the third sealing ring 213 increases the sealing area, further improving the sealing effect of the sealing element 200.
