[0002] In existing technologies, household nightlights typically have limited functionality and a fixed light angle, making them difficult to flexibly adapt to different lighting needs in various usage scenarios. Traditional nightlights on the market may not be able to simultaneously illuminate a corner of a room or adjust the light direction to avoid direct light into the eyes. Furthermore, traditional nightlights are not designed with user-friendliness in mind, failing to allow users to freely adjust the direction of the light.

[0003] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model proposes a night light with a lamp head that can rotate freely and flexibly, so as to achieve adjustable illumination angle.

[0005] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0006] A rotatable and adjustable night light includes a lamp head, a middle connector, a wire, and a plug. One end of the wire is connected to the plug, and the other end passes through the middle connector and connects to the lamp head. The lamp head is connected to the plug via the middle connector. The lamp head has a first annular nesting part. The middle connector includes a connecting sleeve and a rotating accessory. One end of the connecting sleeve has a second annular nesting part that fits into the first annular nesting part. The first and second annular nesting parts fit together. The rotating accessory has a perforated annular groove. One end of a hook passes through the perforated annular groove and is fixed to the lamp head. The other end of the hook is attached to the rotating accessory. The rotating accessory is fixed between the plug and the connecting sleeve.

Detailed Implementation

[0024] The following will be combined with the appendix Figure 1 To be continued Figure 6 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0025] It should be noted that, in the embodiments of this utility model, the directions shown in the accompanying drawings shall prevail, such as front and back. Figure 1 For the sake of accuracy, the specific details should be as follows: Figure 1 The left side is the front. Figure 1 The right side is the rear; at the same time, as Figure 2 As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly.

[0026] refer to Figure 1 and Figure 2 The night light in this embodiment includes a lamp head 1, an intermediate connector 2, and a plug 3.

[0027] The lamp head 1 has a long, annular cavity structure, which reduces material usage and achieves an aesthetically pleasing effect. Of course, the shape of the lamp head 1 is not limited to annular cavity structure; depending on the application scenario, a circular or square structure can also be used. The lamp head 1 is rotatably connected to the plug 3 via the intermediate connector 2. The lamp head 1 is composed of multiple parts, specifically including a main body upper cover 11, a circuit board 12, a lampshade 13, a main body lower cover 14, and a button 15. The main body upper cover 11, lampshade 13, and main body lower cover 14 are made of plastic and are flexible. The main body upper cover 11 has a button hole 111 for the button 15 to be exposed, and the main body upper cover 11 is fixed to the lampshade 13 by a slot and a buckle. The circuit board 12 is fixed between the lampshade 13 and the main body lower cover 14, and the circuit board 12 has LED beads 121. The lampshade 13 and the main body lower cover 14 are fixedly connected by a slot and a buckle, and the main body upper cover 11 and the lampshade 13 are also fixedly connected by a slot and a buckle. The lampshade 13 is typically made of transparent or semi-transparent plastic. The circuit board houses a control module, a light source module, a power supply module, and a light sensor module. The control module, acting as the system control center, processes external commands and sends switch and brightness signals to the light source module. The power supply module continuously supplies power to both the control module and the light source module. The light sensor module detects the ambient light intensity and sends feedback to the control module, which then sends a new brightness signal to the light source module based on the received brightness signal.

[0028] The intermediate connector 2 includes a connecting sleeve 21 and a rotating accessory 22. The connecting sleeve 21 has an outer ring shape and a generally hollow internal structure. The hollow structure of the connecting sleeve 21 has a limiting part that divides the connecting sleeve 21 into an upper space and a lower space. The upper space forms a circular nested part 215, and a limiting post 212 is also provided within this upper space. The rotating accessory 22 is located in the lower space. The limiting part of the connecting sleeve has several slots 214 on one side of the lower space, and the rotating accessory 22 has buckles 223. During assembly, the rotating accessory 22 is secured between the limiting part and the plug 3, and simultaneously, the buckles 223 on the rotating accessory 22 engage with the slots 214 in the limiting part. This structure allows the rotating accessory 22 to be securely assembled within the connecting sleeve 21. The secure assembly of the rotating accessory further ensures more stable operation of the connecting component within the rotating part. The rotating accessory has an overall circular structure, and the central axis of the rotating accessory 22 coincides with the central axis of the connecting sleeve 21. In other embodiments, the rotating accessory is not limited to being circular; it can also be square or rectangular. As long as the central axis of the rotating accessory 22 coincides with the central axis of the connecting sleeve 21, the relative rotation between the intermediate connecting piece 2 and the lamp head 1 can be well achieved.

[0029] The lamp holder 1 is connected to the plug 3 through the intermediate connector 2. One end of the wire 5 is connected to the plug 3, and the other end of the wire 5 passes through the wire hole 222 on the rotating accessory 22, the hollow part 213 of the connecting sleeve 21, and then passes through the lower cover 14 of the main body to connect with the circuit board 12 inside the lamp holder.

[0030] The lower cover 14 of the lamp holder 1 has a first annular nesting portion 141 and a first screw hole 143. The intermediate connector 2 includes a connecting sleeve 21 and a rotating accessory 22. One end of the connecting sleeve 21 has a second annular nesting portion 215 that fits into the first annular nesting portion 141. The second annular nesting portion 215 is fitted inside the first annular nesting portion 141. In this embodiment, the first annular nesting portion 141 protrudes from the lower cover 14, while the corresponding second annular nesting portion 215 is recessed within the connecting sleeve 21. In other embodiments, the first annular nesting portion may be recessed into the lower cover, while the corresponding second annular nesting portion protrudes from the connecting sleeve. (See reference...) Figure 3 and Figure 4 The annular nested part 215 is equipped with a limiting post 212, and the annular nested part 141 is equipped with a limiting beam 142 that matches the limiting post. The matching of the limiting post 212 and the limiting beam 142 prevents excessive rotation between the intermediate connector 2 and the lamp holder 1, which could break the wire. (Reference) Figure 3In a preferred embodiment, the interior of the annular nesting part 141 may also include an annular ring. A circular groove is formed between the outer wall of this annular ring and the inner wall of the annular nesting part 141. Two symmetrical limiting beams 142 are provided in the circular groove, and the limiting post 212 on the connecting sleeve 21 is precisely engaged in the circular groove. When the intermediate connector rotates relative to the lamp head, the limiting post 212 moves within the circular groove. The connecting sleeve 21 is provided with a buckle, and the plug 3 is inserted into the buckle on the connecting sleeve 21, thereby achieving a fixed connection between the plug 3 and the intermediate connector 2. In other embodiments, the plug 3 can also be fixed to the connecting sleeve 21 by screws, or a combination of buckles and screws can be used.

[0031] The rotating accessory 22 is fixed between the plug 3 and the connecting sleeve 21. The rotating accessory 22 has a perforated annular groove. One end of the hook 4 passes through the annular groove 221 and is fixed in the first screw hole 143 of the lower cover 14 of the main body. The other end of the hook 4 is attached to the rotating accessory 22. In this embodiment, the hook is a self-tapping screw. The hook 4 passes through the annular groove 221 and is fixed to the lower cover 14 of the main body, while the rotating accessory 22 is fixed between the plug 3 and the connecting sleeve 21, thus allowing the lamp head to rotate relative to the plug. The light angle can be adjusted by changing the mechanical structure without modifying the power circuit or other modules. Preferably, the annular groove is a pair of symmetrical semicircular arcs, achieving a unique 180° adjustable rotation. Correspondingly, the hook 4 is also a pair of symmetrical hooks.

[0032] The working principle of this utility model is explained below. When the lamp head is rotated, the annular nesting part 141 on the lower cover 14 of the main body of the lamp head rotates relative to the annular nesting part 215 of the connecting sleeve 21. At the same time, since one end of the hook is fixed to the lower cover 14 of the main body of the lamp head, the hook is attached to the end of the rotating accessory and moves in an arc within the annular groove 221 of the rotating accessory 22 as the lamp head rotates. This achieves the relative rotation of the lamp head with respect to the plug. In addition, since one end of the hook is fixed to the lower cover 14 of the main body of the lamp head and the other end of the hook is attached to the rotating accessory, and the rotating accessory is in a mutually fixed state with the connecting sleeve 21, the lower cover 14 of the main body and the connecting sleeve 21 will not detach from each other due to the rotation. When the lamp head and the intermediate connecting part rotate relative to each other, the wire will be pulled to a certain extent, but since we have provided a certain length allowance for the wire, the wire will not be broken.

[0033] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
