Description

Technical Field

[0001] This utility model relates to the field of smart toilet technology, and in particular to a toilet seat assembly and a smart toilet. Background Technology

[0002] Smart toilets are common smart home devices. Existing smart toilets usually use an external power source to power the heating coils and other electrical components in the toilet seat. Although this power supply method is simple to use, it is also limited by the location and number of indoor power outlets, which increases the complexity of installation and maintenance in old house renovations or bathroom installations.

[0003] To address this issue, toilets powered by independent rechargeable power supplies have emerged. This technology utilizes a built-in rechargeable power source as the toilet's independent power source, achieving a power supply method that eliminates the need for an external power source. However, existing independent power supplies typically use a fixed bracket structure to secure the power supply, requiring the use of screws and other fasteners to fix the power supply to the bracket. This fixing method, due to the need to tighten multiple screws, results in a longer installation time, more cumbersome operation, and increased installation difficulty. Furthermore, it is inconvenient to disassemble the power supply for charging. Utility Model Content

Detailed Implementation

[0057] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0058] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0059] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0060] like Figures 1 to 15 As shown, this embodiment discloses a toilet seat assembly, including a base 1, a toilet seat 3 and a power supply device 4. The toilet seat 3 is hinged to the base 1. The base 1 is provided with an upward-opening battery mounting slot 11. The power supply device 4 is installed in the battery mounting slot 11.

[0061] The side wall of the battery mounting slot 11 is provided with a plurality of limiting strips 113, which are spaced apart and installed on the side wall of the battery mounting slot 11. The bottom surface of the battery mounting slot 11 is provided with a plurality of supporting ribs 112 arranged at intervals. The top surfaces of the plurality of supporting ribs 112 are on the same plane and parallel to the horizontal plane. The plurality of limiting strips 113 and the plurality of supporting ribs 112 form a power supply device mounting space. The size of the power supply device mounting space is adapted to the size of the power supply device 4.

[0062] This invention, through the presence of an upward-opening battery mounting groove 11 on the base 1, and the cooperation of several limiting strips 113 and several supporting ribs 112 within the battery mounting groove 11, enables the rapid installation and disassembly of the power supply device 4. The operation is relatively simple, allowing for quick removal of the power supply device 4 for charging. Specifically, the cooperation of the limiting strips 113 restricts the front-back, left-right, and right-side positions of the power supply device 4, while the cooperation of the supporting ribs 112 restricts its vertical position. This fixes the position of the power supply device 4, ensuring a stable installation and preventing displacement. Furthermore, it ensures precise electrical connection between the electrode contacts on the power supply device 4 (i.e., the discharge negative electrode 4232 (P-), the charging negative electrode 4233 (C-), and the charge / discharge positive electrode 4234 (C+ / P+)) and the connection points on the battery mounting groove 11 (the first elastic conductive contact 141, the second elastic conductive contact 142, and the third elastic conductive contact 143).

[0063] Preferably, the supporting rib 112 can be made of a material with high hardness, which can stably support the power supply device 4 in the vertical direction and prevent the power supply device 4 from moving downward.

[0064] Preferably, the limiting strip 113 can be made of a material with a certain degree of elasticity, so that the limiting strip 113 and the power supply device 4 can be assembled by interference fit to form a firm connection.

[0065] In one embodiment, the limiting strip 113 includes a guide portion (not shown in the figure) and a limiting portion (not shown in the figure). The guide portion is installed on the top of the limiting portion, and the guide portion and the limiting portion are smoothly connected. The limiting portions of a plurality of limiting strips 113 and a plurality of supporting ribs 112 form the installation space for the power supply device.

[0066] The cross-sectional area of ​​the guide portion gradually increases from top to bottom, causing the space formed between the guide portions of the plurality of limiting bars 113 to gradually decrease from top to bottom. The guide portion facilitates the rapid installation of the power supply device 4, while the limiting portion ensures the stability after installation, taking into account both convenience and reliability. The cooperation between the guide portion and the limiting portion enables the rapid and reliable installation of the power supply device 4.

[0067] In one embodiment, the toilet seat 3 includes a seat body 31, a bottom cover 33, and a heating device 34. The seat body 31 is hinged to the base 1, and the seat body 31 is connected to the bottom cover 33. A receiving cavity 35 is formed between the seat body 31 and the bottom cover 33. The heating device 34 is installed in the receiving cavity 35, and the heating device 34 abuts against the inner wall of the seat body 31.

[0068] The bottom of the heating device 34 is provided with a heat insulation layer 342.

[0069] Since the top surface of the heating device 34 abuts against the inner wall of the seat body 31, and the bottom of the heating device 34 is provided with a heat insulation layer 342, it can effectively block the heat from being transferred to non-target areas (i.e. downwards), reduce heat loss, and allow the heat generated by the heating device 34 to be transferred upwards to the seat body 31, thereby achieving precise heating of the top of the seat body 31. This can increase the heating rate of the surface of the seat body 31, allowing the surface of the seat body 31 to heat up quickly and shortening the time it takes for the surface of the seat body 31 to reach the target temperature.

[0070] In one embodiment, the heating device 34 includes two symmetrically arranged and electrically connected electric heating films 341, each of which has a heat insulation layer 342 at its bottom, and the two electric heating films 341 are respectively bonded to the inner walls of the left and right sides of the seat body 31.

[0071] The heating film 341 includes an adhesive layer 3411, a first insulating layer 3412, a heating layer 3413, and a second insulating layer 3414 arranged sequentially. In actual assembly, the heating film 341 is firmly adhered to the inner wall surfaces of the left and right sides of the seat ring body through the adhesive layer 3411. This installation method ensures that the heating film 341 is in close contact with the seat ring surface, which can maximize the heat conduction efficiency.

[0072] The heating layer 3413 includes an adhesive layer 34131 and a heating element 34132 embedded within the adhesive layer 34131. The heating element 34132 is arranged in a serpentine pattern within the adhesive layer 34131. The adhesive layer 34131 is made of adhesive material, which not only securely fixes the heating element 34132 but also effectively achieves a tight connection between the heating layer 3413, the first insulating layer 3412, and the second insulating layer 3414. This allows the first insulating layer 3412, the heating layer 3413, and the second insulating layer 3414 to form a sealed and highly insulating sandwich structure, which significantly prevents external moisture from contacting the heating element 34132 and greatly enhances the overall insulation performance, thereby ensuring the safe and stable operation of the heating device.

[0073] Preferably, the adhesive material 34131 is selected from materials with good thermal stability and insulating properties. In some embodiments, the adhesive material 34131 may be a high-temperature resistant epoxy resin, but is not limited thereto.

[0074] Preferably, the electric heating film 341 is arc-shaped; the symmetrical and double-arc design not only allows the electric heating film 341 to better fit the shape of the toilet seat, but also allows the two electric heating films 341 to be installed inside the toilet seat, which can more accurately match the human contact area, so that the human contact area on the toilet seat can be heated quickly, reducing heat loss and improving heating efficiency.

[0075] In one embodiment, the heating element 34132 includes a first heating wire 341321 and a second heating wire 341322. The starting end of the first heating wire 341321 and the starting end of the second heating wire 341322 are connected, forming a first bonding area 341323 at the connection point; the ending end of the first heating wire 341321 and the ending end of the second heating wire 341322 are connected, forming a second bonding area 341324 at the connection point.

[0076] The first heating wire 341321 and the second heating wire 341322 are arranged in a serpentine manner in the front and rear regions of the adhesive layer 34131, respectively.

[0077] The first heating wire 341321 and the second heating wire 341322 are arranged in a serpentine pattern at different locations on the adhesive layer 34131, covering the entire heating layer 3413. This arrangement enables large-area uniform heating, distributing heat evenly across the area covered by the heating layer 3413, preventing localized overheating or underheating, improving heating uniformity and stability, and enhancing the overall performance and reliability of the heating device. The serpentine arrangement allows for increased heating wire length within a limited space, thereby increasing heating power and heating speed without significantly increasing volume. It also effectively utilizes space, resulting in a more compact heating element structure. Furthermore, this arrangement increases the contact area between the heating element 34132 and the inner wall of the seat ring, facilitating rapid heat dissipation and improving heat dissipation efficiency, thus enabling the upper surface of the seat ring to quickly reach the target temperature.

[0078] Preferably, the materials of the first heating wire 341321 and the second heating wire 341322 are one of graphene, a metallic element, and a metal alloy. In some embodiments, the metallic element may be copper, and the metal alloy may be a nickel-chromium alloy, an iron-chromium-aluminum alloy, a copper-nickel alloy, etc.

[0079] Preferably, the materials of the first insulating layer 3412 and the second insulating layer 3414 are both PET film or PI film.

[0080] PI film, or polyimide film, is a high-performance film material with excellent high-temperature resistance, radiation resistance, chemical corrosion resistance, and electrical insulation properties. It can be used for a long time in a temperature range of -269℃ to 400℃.

[0081] In some embodiments, the adhesive layer 3411 is made of double-sided adhesive.

[0082] Preferably, the thickness of the heating film 341 is 0.24mm to 0.8mm. This thickness range allows for rapid heat conduction, enabling the heat generated by the heating film 341 to be quickly transferred to the upper surface of the toilet seat, further shortening the heating waiting time and avoiding the heating lag caused by excessive thickness. Furthermore, this thickness range maintains sufficient mechanical strength, ensuring that the heating film does not deform or crack during long-term use, while also maintaining good flexibility to adapt to the curved surface of the toilet seat.

[0083] In some embodiments, the heat insulation layer 342 is made of one of the following materials: a nano-aerogel film, a microporous polyimide film, and a porous vacuum silicon film. These materials all have good heat insulation and high temperature resistance properties, can effectively block heat transfer to non-target areas (i.e., downward transfer), and have a certain degree of flexibility to adapt to curved seat rings.

[0084] In one embodiment, the area of ​​the seat body 31 that comes into contact with the human body is a heating part 311, and the remaining area is a non-heating part. The wall thickness of the heating part 311 is less than the wall thickness of the non-heating part.

[0085] Preferably, the toilet seat 3 further includes a support base 32, which is installed in the receiving cavity 35. The bottom surfaces of the heating device 34 and the heating part 311 abut against each other, the top surface of the support base 32 abuts against the heating device 34, and the bottom of the support base 32 is connected to the bottom cover 33.

[0086] This invention improves the overall structure of the toilet seat 3 by incorporating a thin heating element 311 within the seat body 31. Due to the thinness of the heating element 311 and the close contact between the heating device 34 and the bottom surface of the heating element 311, heat transfer efficiency is effectively enhanced, allowing the surface of the seat body 31 to heat up quickly and reach a comfortable temperature (30-40°C). This significantly shortens the heating time of the seat surface and improves the user experience. Furthermore, by providing a support seat 32 within the receiving cavity 35, with one end extending to the heating device 34 and the other end extending to the bottom cover 33, the thin heating element 311 is supported, and the overall strength and rigidity of the toilet seat 3 are improved. This allows the toilet seat to withstand greater external forces and loads without deformation or damage, thereby extending the service life of the toilet seat.

[0087] In one embodiment, the heating element 311, the heating film 341, and the support base 32 are shaped to match each other, with the top surface of the heating film 341 abutting against the bottom surface of the heating element 311, and the top surface of the support base 32 abutting against the bottom surface of the heat insulation layer 342.

[0088] Preferably, the thickness of the heating part 311 (i.e. the wall thickness of the heating part) is ≤2mm; within this thickness range, the heat transfer speed can be effectively improved, so that the surface of the seat body 31 can be heated quickly.

[0089] In one embodiment, the thickness of the heating part 311 is 0.4mm to 1.5mm, which can further improve the heat transfer speed, so that the surface of the seat body 31 can be heated up quickly and reach a comfortable temperature (30 to 40°C), further shortening the time for the surface of the seat body 31 to reach the target temperature, and further improving the user's comfort and experience.

[0090] It should be noted that the thickness of the heating part 311 should not be less than 0.4 mm. If the thickness is too thin, the heating part 311 will be difficult to form during the preparation of the seat body 31, which will reduce the pass rate of the seat body 31 production.

[0091] In one embodiment, the thickness of the heating part 311 is 0.4 mm to 1 mm. By further reducing the thickness of the heating part 311, the heat transfer speed can be further improved, so that the surface of the seat body 31 heats up more quickly and reaches a comfortable temperature (30 to 40°C), and the time for the surface of the seat body 31 to reach the target temperature is further shortened.

[0092] Specifically, the thickness of the heating part 311 is exemplarily 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, or 1mm, but is not limited thereto.

[0093] In one embodiment, the heating part 311 is provided on the left and right sides of the seat body 31 respectively;

[0094] The bottom surface of the seat body 31 in the area corresponding to the heating part 311 is recessed upward to form a heating groove 312, that is, the upper wall of the heating groove 312 is the bottom surface of the heating part 311, and the electric heating film 341 is installed in the heating groove 312.

[0095] Preferably, the heating film 341 is adhered to the bottom surface of the heating part 311 by means of adhesive, which can achieve close contact, reduce energy loss, and improve the heat transfer effect.

[0096] In one embodiment, the support base 32 includes a support panel 321 and a support portion 322, the support portion 322 being mounted on the bottom of the support panel 321, and the bottom of the support portion 322 being connected to the bottom cover 33.

[0097] The shape of the support panel 321 matches the shape of the heating groove 312. The top of the support panel 321 extends into the heating groove 312, and the top surface of the support panel 321 abuts against the bottom surface of the heating device 34. The support base 32 of this embodiment can stably support the heating part 311 and improve the overall strength and rigidity of the toilet seat.

[0098] In one embodiment, the support portion 322 is composed of a plurality of reinforcing ribs. By rationally designing the layout and shape of the reinforcing ribs, the amount of material used can be reduced while ensuring the strength and rigidity of the toilet seat. Because the reinforcing ribs can significantly improve the strength and rigidity of the toilet seat without increasing the overall thickness of the toilet seat, lightweight design can be achieved, production costs can be reduced, and it is also beneficial to resource conservation and environmental protection.

[0099] In one embodiment, the seat body 31 has a snap-fit ​​portion 313 on the outer periphery of the heating groove 312, and the bearing panel 321 has a limiting groove 3211 on the outer periphery. The snap-fit ​​portion 313 and the limiting groove 3211 are snapped together. Through the cooperation of the snap-fit ​​portion 313 and the limiting groove 3211, displacement of the support seat 32 can be effectively prevented, thereby achieving a better support effect, avoiding deformation or damage to the heating part 311, further improving the overall strength and rigidity of the toilet seat, and extending the service life of the toilet seat.

[0100] Preferably, the electrothermal film 341 is a graphene electrothermal film or a metal electrothermal film.

[0101] In one embodiment, the battery mounting groove 11 is provided with a drain hole 111, and the bottom surface of the battery mounting groove 11 is inclined from the side away from the drain hole 111 to the side close to the drain hole 111, forming a directional drainage slope.

[0102] The base 1 is provided with a drainage groove 12, which is located on the outer periphery of the battery mounting groove 11, and the drainage groove 12 is connected to the drainage hole 111;

[0103] The power supply device 4 includes a cover 41 and a power supply body 42. The cover 41 is installed on the top of the power supply body 42. The cover 41 protrudes around the power supply body 42. The bottom surface of the cover 41 is provided with a protruding guide portion 411 that cooperates with the drainage groove 12. The protruding guide portion 411 is inserted into the drainage groove 12.

[0104] This invention incorporates a drainage design in the battery mounting slot 11. The inclined bottom surface of the battery mounting slot and the drainage hole work together to actively guide water into the slot and prevent water retention. This effectively protects the power supply device 4, preventing short circuits and electrode oxidation, ensuring stable operation of functions such as seat heating and warm air drying in the smart toilet, and extending the lifespan of the power supply device 4. Furthermore, the top surface of the supporting rib 112 is parallel to the horizontal plane, ensuring the power supply device 4 is securely installed and not easily shaken or shifted. This facilitates precise contact between the electrode contacts on the power supply device 4 and the connection contacts on the battery mounting slot 11, ensuring reliable electrical connections without affecting the drainage function, thus balancing stability and waterproofing. Due to the drainage and supporting rib designs in the battery mounting slot 11, the power supply device 4 can be directly inserted into the slot. When charging is needed, simply pull the power supply device 4 out of the slot, greatly reducing the difficulty and complexity of installation and disassembly. Therefore, it can ensure that the independent power supply 4 is easy to install while also maintaining good waterproof performance.

[0105] Furthermore, the cooperation between the drain groove 12 and the raised guide portion 411 allows water dripping onto the surface of the lid 41 to be quickly guided into the drain groove 12 and discharged through the drain hole 111, preventing water from entering the battery mounting slot 11 and further enhancing waterproof performance. The cooperation between the drain groove 12 and the raised guide portion 411 forms a physical barrier, preventing water from entering the battery mounting slot 11 and enhancing the protective capabilities of the toilet seat assembly.

[0106] In one embodiment, the bottom surface of the battery mounting groove 11 is inclined at an angle of 1° to 15° from the side away from the drain hole 111 to the side closer to the drain hole 111. Within this limited range, the inclination angle effectively drains water from the battery mounting groove 11 and facilitates reliable installation of the power supply device 4. Exemplarily, the inclination angle is 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, or 15°, but is not limited to these.

[0107] More preferably, the bottom surface of the battery mounting groove 11 is inclined at an angle of 2° to 9° from the side away from the drain hole 111 to the side closer to the drain hole 111.

[0108] In one embodiment, the lifting cover 41 includes a first inclined portion 412 and a second inclined portion 413 that are smoothly connected to each other. The first inclined portion 412 is located on the side of the lifting cover 41 that is close to the toilet seat 3. The first inclined portion 412 is inclined from the side away from the toilet seat 3 to the side that is close to the toilet seat 3. The second inclined portion 413 is inclined from the side that is close to the toilet seat 3 to the side that is away from the toilet seat 3.

[0109] The drainage channel 12 includes a first drainage section 121 and a second drainage section 122 disposed on the left and right sides of the battery mounting slot 11. The first drainage section 121 is disposed on the side of the battery mounting slot 11 near the toilet seat 3. The second drainage section 122 is connected to the first drainage section 121. The first drainage section 121 is connected to the drain hole 111.

[0110] When there is water on the surface of the cover 41, the water can flow along the surface of the first inclined portion 412 toward the first drainage section 121 and fall into the first drainage section 121. Since the first drainage section 121 and the drainage hole 111 are connected, the water can be discharged to the outside of the battery mounting slot 11 through the drainage hole 111, preventing water from entering the battery mounting slot 11. Alternatively, the water on the surface of the cover 41 can also flow along the surface of the second inclined portion 413 toward the outside of the base, preventing water on the surface of the cover 41 from entering the battery mounting slot 11.

[0111] This invention uses the first inclined portion 412 and the second inclined portion 413 to guide water from the surface of the cover 41 to the drainage channel or the outside of the base, respectively. This dual waterproof path ensures that no water accumulates in the battery mounting slot 11. The first drainage section 121 and the second drainage section 122 cover multiple directions of the battery mounting slot 11, ensuring all-around drainage and improving waterproof reliability.

[0112] In one embodiment, the base 1 has a drainage groove 13 inside, the drain hole 111 is connected to the input end of the drainage groove 13, and the output end of the drainage groove 13 is connected to the outside of the base 1. Through the cooperation of the drain groove 12, the drain hole 111 and the drainage groove 13, the water accumulated in the battery mounting groove 11 and the water dripping onto the surface of the cover 41 can be discharged to the outside of the base 1, forming a complete drainage path, completely avoiding the water accumulation problem, and ensuring the safety and stability of the power supply device 4.

[0113] In one embodiment, the power supply body 42 includes a top cover 421, a battery housing 422, and a power supply component 423. The battery housing 422 and the top cover 421 are fixedly connected, and a power supply component mounting cavity 424 is formed between the battery housing 422 and the top cover 421. The power supply component 423 is installed in the power supply component mounting cavity 424.

[0114] The lifting cover 41 is fixedly installed on the top of the top cover 421.

[0115] The power supply device 4 of this utility model has an integrated structure, which can improve the safety of the power supply device 4 and facilitate quick installation and removal of the power supply device 4.

[0116] In one embodiment, the power supply unit 423 is provided with a first charging interface 4231, a discharge negative electrode 4232 (P-), a charging negative electrode 4233 (C-), and a charge / discharge positive electrode 4234 (C+ / P+).

[0117] The base 1 is provided with a first elastic conductive contact 141, a second elastic conductive contact 142, a third elastic conductive contact 143, and a second charging interface 15. The first elastic conductive contact 141, the second elastic conductive contact 142, and the third elastic conductive contact 143 protrude from the side wall surface of the battery mounting groove 11. The first elastic conductive contact 141 is used to electrically connect with the discharge negative terminal 4232 (P-), the second elastic conductive contact 142 is used to electrically connect with the charging negative terminal 4233 (C-), and the third elastic conductive contact 143 is used to electrically connect with the charging / discharging positive terminal 4234 (C+ / P+). Through the design of the first elastic conductive contact 141, the second elastic conductive contact 142, and the third elastic conductive contact 143, the electrical connection between the power supply device 4 and the base 1 can be ensured to be stable and reliable, thereby enabling power supply to the electrical devices and avoiding power supply problems caused by poor contact.

[0118] The second charging interface 15 is disposed on one side of the base 1, and the port of the second charging interface 15 extends to the side of the base 1. The second elastic conductive contact 142 and the third elastic conductive contact 143 are electrically connected to the second charging interface 15 respectively. The second charging interface 15 is used to connect to an external charger to charge the power supply device 4.

[0119] It is worth noting that the toilet seat assembly of this utility model features a dual charging port design, supporting both charging by removing the power supply device 4 and charging directly through the base 1, thus meeting diverse user needs and enhancing usability. Preferably, the first charging port 4231 and the second charging port 15 can be configured for slow charging mode and / or fast charging mode, respectively. For example, in one embodiment, the first charging port 4231 can be configured for slow charging mode, and the second charging port 15 can be configured for fast charging mode.

[0120] Specifically, the base 1 is provided with a main control circuit, and the first elastic conductive contact 141, the second elastic conductive contact 142, the third elastic conductive contact 143 and the second charging interface 15 are electrically connected to the main control circuit respectively.

[0121] In one embodiment, the power supply unit 423 includes a battery pack, a battery mounting bracket, a battery circuit board, and a charging / discharging substrate. The battery pack is mounted on the battery mounting bracket, the battery pack and the battery circuit board are electrically connected, the charging / discharging substrate and the battery circuit board are electrically connected, the discharge negative electrode (P-), the charging negative electrode (C-), and the charging / discharging positive electrode (C+ / P+) are respectively disposed on the charging / discharging substrate, and the first charging interface 4231 is connected to the battery circuit board.

[0122] In one embodiment, the power supply unit 42 further includes a display component 425, which is mounted on the top cover 421. The display component 425 is electrically connected to the power supply unit 423 and is used to provide real-time feedback on the power status of the power supply unit 423 (such as power level, charging and discharging status, etc.).

[0123] The display component 425 includes a plurality of indicator lights 4251, a light-blocking component 4252 and a light guide component 4253. The light-blocking component 4252 is provided with a plurality of indicator light mounting through holes 42521, and the plurality of indicator lights 4251 are respectively installed in the plurality of indicator light mounting through holes 42521.

[0124] The light guide 4253 is installed on the top of the light blocker 4252.

[0126] The light-blocking component 4252 is made of a light-shielding material. Installing the indicator light 4251 within the indicator light mounting through-hole 42521 prevents the light emitted by the indicator light 4251 from scattering in all directions, ensuring that the light emitted by the indicator light 4251 only scatters upwards through the indicator light mounting through-hole 42521. The light guide component 42531 is made of a transparent material such as epoxy resin. Through the light guiding effect of the light guide component 42531, the light emitted by the indicator light 4251 is emitted through the display hole 415. The cooperation of the indicator light 4251, the light-blocking component 4252, and the light guide component 4253 clearly displays the power status (such as battery level and charging / discharging status), enhancing the user's interactive experience. The synergistic effect of the light-blocking component 4252 and the light guide component 4253 prevents light scattering, ensures concentrated display brightness, and allows users to intuitively obtain power information.

[0127] In one embodiment, the power supply device 4 further includes a handle 43 and a rotating component 44. The handle 43 is movably mounted to the cover 41 via the rotating component 44.
