[0025] Example 1: like Figure 1 As shown, this embodiment proposes a portable night light, including: The housing assembly includes a first housing 11, a receiving cavity is provided inside the first housing 11, and a first opening 111 and a second opening 112 are provided at both ends of the first housing 11. A light source assembly is disposed within the accommodating cavity, with its emitting surface facing the first opening 111; and The battery assembly includes a first magnetic housing 31, a second magnetic housing 32, and a battery box 33. The first magnetic housing 31 is disposed at the second opening 112. The first magnetic housing 31 is provided with a first magnetic surface 311, and the second magnetic housing 32 is provided with a second magnetic surface 321. The first magnetic surface 311 and the second magnetic surface 321 are aligned and magnetically attracted. The second magnetic surface 321 is provided with a charging base 322, the first magnetic surface 311 is provided with a charging channel 312, and the battery assembly is provided on a surface of the first magnetic housing 31 away from the first magnetic surface 311. The battery assembly is aligned with the charging channel 312 so that when the first magnetic surface 311 and the second magnetic surface 321 are in contact, the charging base 322 connects to the charging channel 312 to charge the battery assembly.

[0026] Specifically, the housing assembly includes a first housing 11, which can be configured with an outwardly convex arc-shaped sidewall to form an internal accommodating cavity. The accommodating cavity has a first opening 111 and a second opening 112. The first opening 111 is for light transmission, and the second opening 112 is for power connection. The first housing 11 can be configured as a semi-transparent housing, allowing light to partially pass through the first housing 11 and through the first opening 111. The light source assembly generates light, allowing light to partially pass through the first housing 11 and through the first opening 111. To address the problem of the night light needing to be plugged in and the difficulty of plugging and unplugging it, a battery assembly is provided. The battery assembly includes a first magnetic surface 311 and a second magnetic housing 32 with a second magnetic surface 321. At least one side of the first magnetic surface 311 and the second magnetic surface 321 is provided with a magnet; the other side can be a magnet or metal, allowing the first magnetic surface 311 and the second magnetic surface 321 to attract each other. A charging base 322 is provided on the second magnetic surface 321, and a charging slot 312 is provided on the first magnetic surface 311. The battery assembly is located on the surface of the first magnetic housing 31 away from the first magnetic surface 311, and is aligned with the charging slot 312. In use, when the first magnetic surface 311 and the second magnetic surface 321 are in contact, the charging base 322 connects to the charging slot 312 to charge the battery assembly. This method allows the second magnetic housing 32 to be connected to a socket at one end via a wire, with the other end supplying power to the charging base 322. This enables the second magnetic housing 32 to be moved to any location without relying on a socket. Simultaneously, the night light body is connected and disconnected magnetically, solving the problem of difficulty in plugging and unplugging the night light from the socket.

[0027] Furthermore, the battery assembly can be an energy storage battery. After the nightlight body is charged by being attracted to the first magnetic housing 31 and the second magnetic housing 32, the first magnetic housing 31 can be detached, allowing the nightlight light source 22 to be moved to other positions. The second magnetic housing 32 can also contain an energy storage battery. After charging the energy storage battery within the second magnetic housing 32, the second magnetic housing 32 can supply power independently without being connected to a socket. This, combined with the energy storage battery within the battery assembly, allows the nightlight to be powered without a socket, and the second magnetic housing 32 can function as a power supply compartment.

[0028] The housing assembly includes a first housing 11, which has a receiving cavity inside. The housing assembly has a first opening 111 and a second opening 112 at both ends. A light source assembly is disposed within the receiving cavity, with its light-emitting surface facing the first opening 111. A battery assembly includes a first magnetic housing 31, a second magnetic housing 32, and a battery compartment 33. The first magnetic housing 31 is located at the second opening 112 and has a first magnetic surface 311. The second magnetic housing 32... The device is equipped with a second magnetic surface 321, which is aligned with and magnetically attracted to the first magnetic surface 311 and the second magnetic surface 321. A charging base 322 is mounted on the second magnetic surface 321, and a charging slot 312 is provided on the first magnetic surface 311. The battery assembly is positioned on the surface of the first magnetic housing 31 away from the first magnetic surface 311, aligned with the charging slot 312. This arrangement ensures that when the first magnetic surface 311 and the second magnetic surface 321 are in contact, the charging base 322 connects to the charging slot 312 to charge the battery assembly. This battery assembly eliminates the need for the night light to be plugged into a power outlet, and avoids the problem of difficulty in plugging and unplugging the night light.

[0029] Example 2: like Figures 2-11 As shown, this embodiment further explains and optimizes the structure proposed in Embodiment 1: In some embodiments, the battery assembly includes a voice component disposed within the battery compartment 33 to recognize voice and control the light source assembly.

[0030] Specifically, by setting up a voice component (not shown in the figure), which is also a voice recognition module, the night light can recognize voice and execute functions. The voice component is set in the battery box 33 or in the accommodating cavity, so that the night light can be controlled by voice without electronic devices such as switches. It also has a built-in personalized adjustment function, which executes the corresponding function by recognizing voice, making the night light more intelligent.

[0031] In some embodiments, a charging port 323 is provided on one side of the second magnetic housing 32, and the charging port 323 is electrically connected to the charging base 322.

[0032] Specifically, the charging port 323, which can be a Type-C port, is electrically connected to the charging base 322. A plug and a Type-C charging cable can then be connected from the socket to the charging port 323 to supply power to the charging base 322. This avoids the need for the night light to be directly plugged into the socket, which not only occupies space around the socket but also makes the night light's usage dependent on the socket's location.

[0033] In some embodiments, a snap-fit ​​structure 324 is provided on a surface of the second magnetic housing 32 that is away from the charging base 322.

[0034] Specifically, the snap-on structure 324 can be a back-hanging structure, so that the second magnetic housing 32 can be hung on any hook, further improving the convenience of the night light and making it more suitable for various usage scenarios.

[0035] In some embodiments, the light source assembly includes a circuit board 21 and a light source 22. The circuit board 21 is snapped into the second opening 112. The light source 22 and the battery box 33 are disposed on the light-emitting surface 23 of the circuit board 21 near the first opening 111. The battery box 33 is disposed in the middle of the circuit board 21.

[0036] Specifically, the light source assembly includes a circuit board 21 and a light source 22. The light source 22 emits light and is controlled by the circuit board 21. The circuit board 21 is snapped into the second opening 112. The structure of the circuit board 21 can be consistent with the structure of the second opening 112, so that the circuit board 21 can be fixed in the second opening 112 by means of adhesive, snapping, etc. A voice control module can be set on the circuit board 21 so that the night light can be controlled by voice. The light source 22 and the battery box 33 are set on the light-emitting surface 23 of the circuit board 21 near the first opening 111, so that the light source 22 emits light through the first opening 111, or the light shines through the first housing 11. The battery box 33 is set in the middle of the circuit board 21. For example, if the circuit board 21 is circular, the battery box 33 is set at the center of the circle. Multiple light sources 22 are arranged around the battery box 33 so that the light can be more evenly diffused outside the night light.

[0037] In some embodiments, a fixing seat 313 is provided on the surface of the first magnetic housing 31 away from the first magnetic surface 311. The fixing seat 313 is provided with a first fixing hole 314, and the circuit board 21 is provided with a second fixing hole 24. The battery box 33 is fixed on the first magnetic housing 31 through the first fixing hole 314 and the second fixing hole 24.

[0038] Specifically, a fixing seat 313 is provided on the surface of the first magnetic housing 31 away from the first magnetic surface 311. The fixing seat 313 is provided with a first fixing hole 314. The circuit board 21 is provided with a second fixing hole 24. An opening may be provided at the bottom of the battery box 33 housing. Screws pass through the opening at the bottom of the battery box 33 to the second fixing hole 24 and then to the first fixing hole 314 to lock and fix it, so that the fixing seat 313 not only fixes the battery box 33 but also fixes the circuit board 21, so that the entire light source assembly and the battery box 33 are fixed inside the first housing 11.

[0039] In some embodiments, the light source assembly is provided with a retaining ring (not shown in the figure), which is snapped onto the light source 22.

[0040] Specifically, the light source 22 is mounted on the circuit board 21. To prevent the light source 22 from falling off, a retaining ring is provided to fix it to the light source 22 on the circuit board 21, thereby preventing the light source 22 from falling off when the night light is used at different angles.

[0041] In some preferred embodiments, a heat dissipation groove is provided on the second opening 112 of the first housing 11, and the bottom of the heat dissipation groove extends above the light-emitting surface 23.

[0042] Specifically, a heat dissipation groove is provided at the second opening 112 of the first housing 11, and the bottom of the heat dissipation groove extends above the light-emitting surface 23 so that the heat emitted by the light source 22 can be dissipated from the first housing 11 through the inside of the heat dissipation groove.

[0043] In some embodiments, the housing assembly further includes a retaining ring 12 and a top cover 13. The retaining ring 12 is provided with a snap-fit ​​portion 121 and a mounting portion 122. The first opening 111 is provided with a snap-fit ​​platform 1111. The snap-fit ​​platform 1111 is provided with a snap-fit ​​groove 1112. The snap-fit ​​portion 121 is provided with a first snap-fit ​​protrusion 1211 on its outer side, so that the first snap-fit ​​protrusion 1211 extends into the snap-fit ​​platform 1111 from the snap-fit ​​groove 1112. The retaining ring 12 is fixed at the first opening 111 by a knob. The top of the mounting portion 122 is provided with a mounting step 1221, so that the top cover 13 is mounted on the mounting step 1221.

[0044] Specifically, this structure allows the retaining ring 12 and the top cover 13 to be fixed by a knob, so that the retaining ring 12 and the top cover 13 are set as protective components at the first opening 111.

[0045] In some embodiments, the top cover 13 is provided with a plurality of light transmission curves, which are composed of a plurality of light transmission holes 132 arranged together. The top cover 13 is provided with a blocking part 131 at its center, and the light transmission curves are formed by extending from the blocking part 131 to the outside of the top cover 13.

[0046] Specifically, the top cover 13 is provided with multiple light-transmitting curves, which are formed by multiple light-transmitting holes 132 arranged to allow light and voice to pass through the light-transmitting curves. The top cover 13 is provided with a blocking part 131 in the center, and a touch sensor can be provided at the bottom of the blocking part 131 so that the night light can be turned on and off by touching the blocking part 131.

[0047] In some embodiments, the second opening 112 is provided with a plurality of fixed steps 114, and the second magnetic housing 32 is provided with a second snap-fit ​​protrusion 315, which snaps onto the fixed steps 114.

[0048] Specifically, the second opening 112 is provided with multiple fixed steps 114, the second magnetic housing 32 is provided with a second snap-fit ​​protrusion 315, and the first housing 11 can be made of a soft material, such as plastic, so that the second snap-fit ​​protrusion 315 can be snapped onto the fixed steps 114 by deformation.
