[0002] Night lights are common small indoor lights. Because of their soft light, they are often used at night. When turned on, they not only have the function of night lighting, but also will not affect other people's rest.

[0003] There are many existing technologies for smart night lights, such as:

[0004] Chinese patent announcement number CN211952568U discloses an intelligent induction night light, which includes a base, a light strip, a circuit board and a battery. A light guide plate is arranged at the lower end of the base, a diffusion plate is arranged on the top of the light guide plate, the light strip is arranged in a ring shape on the wall of the base, and lamp beads are arranged on the edge wall of the light strip corresponding to the diffusion plate, the circuit board and the battery are arranged above the diffusion plate, and the battery and the light strip are connected to the battery through wires, and a sensing probe is fixed at the bottom of the circuit board, and the sensing probe passes through the diffusion plate and the light guide plate and extends to the outside of the base. By arranging the light strip in a ring shape on the wall of the base, and the lamp beads on the light strip are directed to the edge wall of the corresponding diffusion plate, the lighting intensity of the night light is enhanced, and this structure facilitates the installation of the lamp group and improves production efficiency; by fixing the sensing probe at the bottom of the circuit board, the human body can be automatically sensed and the light can be turned on at night or in a dark space, providing people with the necessary lighting function at night, and facilitating getting up and falling asleep at night.

[0005] Existing night lights can only be controlled by manual switches, which is inconvenient to use.

[0006] In view of this, we propose an intelligent night light, which realizes that the night light automatically turns off when the user lies down and automatically turns on when the user sits up through the pressure sensing module, signal processing module and signal output module arranged in the pressure sensing pad. In addition, the wire wrapped around the winding assembly is limited by the set limit component, thereby preventing the risk of the wire falling off and electric shock caused by accidental pulling by the user. Utility Model Content

[0007] The purpose of the utility model is to provide an intelligent night light to solve the problems raised in the above background technology.

[0008] To achieve the above-mentioned purpose, the utility model provides an intelligent night light, including a pressure sensing pad, a light bulb and a wire, the pressure sensing pad and the light bulb are electrically connected through the wire, a winding assembly is provided between the pressure sensing pad and the light bulb, the winding assembly is used to wind the wire between the pressure sensing pad and the light bulb, one end of the winding assembly is coaxially connected to a limiting assembly, the limiting assembly is used to limit the relative length of the wire between the pressure sensing pad and the light bulb, and prevent the wire from falling off at the joint between the pressure sensing pad and the light bulb, and at least a pressure sensing module, a signal processing module and a signal output module are provided inside the pressure sensing pad.

[0009] As a further improvement of the technical solution, the winding assembly includes a pair of spaced-apart limit bolts, a rotating shaft is rotatably connected between the limit bolts, and a winding drum is fixedly connected to the periphery of the rotating shaft.

[0010] As a further improvement of the present technical solution, the limit assembly includes a ratchet coaxially connected to the rotating shaft and a limit frame fixedly connected to the inner ring of the winding drum. The inner ring of the limit frame is rotatably connected to a plurality of ratchets, and the ends of the plurality of ratchets away from the limit frame are clamped with the outer ring of the ratchet.

[0011] As a further improvement of the technical solution, a torsion spring is provided between the rotating shaft and the winding drum, the inner ring of the torsion spring is fixedly connected to the outer ring of the rotating shaft, and the outer ring of the torsion spring is fixedly connected to the inner ring of the winding drum.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. In the intelligent night light, the pressure sensing module, signal processing module and signal output module are arranged in the pressure sensing pad, so that the night light is automatically turned off when the user lies down and automatically turned on when the user sits up.

[0014] 2. In the smart night light, a limiting component is provided to limit the wire wound on the winding component, thereby preventing the risk of the wire falling off and electric shock caused by accidental pulling by the user.

[0015] 3. In this smart night light, a rubber anti-slip layer is set on the surface of the pressure sensing pad to prevent the pressure sensing pad from sliding from the head of the user's bed to the foot of the bed. As a result, when the user sits up, the pressure sensing module cannot sense the pressure change on the surface of the pressure sensing pad, which in turn causes the light bulb to be unable to receive the trigger switch signal sent by the signal output module, and the light bulb cannot be turned on automatically.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example

[0029] See also Figure 1-Figure 4As shown, the present embodiment provides an intelligent night light, including a pressure sensing pad 10, a light bulb 20 and a wire 30. The pressure sensing pad 10 and the light bulb 20 are electrically connected through the wire 30. A winding assembly 40 is provided between the pressure sensing pad 10 and the light bulb 20. The winding assembly 40 is used to wind the wire 30 between the pressure sensing pad 10 and the light bulb 20. One end of the winding assembly 40 is coaxially connected to a limiting assembly 50. The limiting assembly 50 is used to limit the relative length of the wire 30 between the pressure sensing pad 10 and the light bulb 20 to prevent the wire 30 from falling off at the joint between the pressure sensing pad 10 and the light bulb 20. At least a pressure sensing module, a signal processing module and a signal output module are provided inside the pressure sensing pad 10; the pressure sensing module, the signal processing module and the signal output module All of them are prior art, and their working principles are as follows: the pressure sensing module is responsible for converting the pressure applied to the sensor into an electrical signal, such as a resistance value, a capacitance value or an electrical signal in other forms; the signal processing module receives the electrical signal from the pressure sensing module, and processes it to ensure that the output signal is stable and accurate. In this case, the signal processing circuit amplifies, filters and linearizes the signal from the sensing element to ensure that the operation of the bulb 20 switch can accurately respond to the pressure change applied to the sensor; the signal output module converts the processed electrical signal into a form that can be read by an external system or device. In this case, the signal output module converts the processed signal into a signal format compatible with the bulb 20 switch control circuit.

[0030] Working principle: When the smart night light provided by the utility model is used, the limit component 50 is set to limit the relative length of the wire 30 between the pressure sensing pad 10 and the bulb 20 to prevent the wire 30 from falling off at the joint between the pressure sensing pad 10 and the bulb 20. The torsion spring 60 set between the rotating shaft 42 and the winding drum 43 is used to automatically drive the winding assembly 40 to reset when the limit component 50 on the winding assembly 40 is removed.

[0031] In order to adjust the relative length of the wire 30 between the pressure sensing pad 10 and the light bulb 20, the winding assembly 40 includes a pair of spaced-apart limit bolts 41, a rotating shaft 42 is rotatably connected between the limit bolts 41, and a winding drum 43 is fixedly connected to the outer periphery of the rotating shaft 42; the winding drum 43 is used to wind the excess length of the wire 30 around the surface, and then the relative length of the loose wire 30 is adjusted by rotating the winding drum 43 forward and reversely around the rotating shaft 42.

[0032] Considering the need to prevent the joints between the wire 30 and the pressure sensing pad 10 and the light bulb 20 from falling off due to accidental pulling, the limiting assembly 50 includes a ratchet 51 coaxially connected to the rotating shaft 42 and a limiting frame 53 fixedly connected to the inner circle of the winding drum 43. The inner circle of the limiting frame 53 is rotatably connected with a plurality of ratchets 52, and the ends of the plurality of ratchets 52 away from the limiting frame 53 are all engaged with the outer circle of the ratchet 51; the ratchet 51 is fixed by a central axis, and its outer circle has a series of ratchets arranged at even intervals. When an external force acts on the ratchet 51, the ratchets will start to rotate under the action of torque. The special shape of the ratchets makes them only rotate in one direction and are blocked in the other direction. When the ratchet 51 rotates, they will pass through the ratchets adjacent to them one by one. This transmission method effectively transmits the input torque to the next ratchets to achieve power transmission. This transmission method of transmitting only one ratchet at a time makes the ratchet 51 have higher accuracy and stability when transmitting power. Therefore, the winding drum 43 can only drive the wire 30 to rotate forward, loosening the wire 30 originally wound on the winding drum 43. When the winding drum 43 has a tendency to reverse, the ratchet 52 will lock the position of the ratchet wheel 51 to prevent the winding drum 43 from tightening the loosened wire 30.

[0033] In order to automatically reset the winding assembly 40 when the restriction of the limit assembly 50 on the winding assembly 40 is removed, a torsion spring 60 is provided between the rotating shaft 42 and the winding drum 43, and the inner circle of the torsion spring 60 is fixedly connected to the outer circle of the rotating shaft 42, and the outer circle of the torsion spring 60 is fixedly connected to the inner circle of the winding drum 43; if the winding drum 43 is accidentally pulled, the wire 30 is driven to rotate around the rotating shaft 42 at a certain angle, causing the torsion spring 60 to be tightened. After the restriction of the pawl 52 on the ratchet wheel 51 is removed, the winding drum 43 is reversed and reset around the rotating shaft 42 under the action of the restoring force of the torsion spring 60.

[0034] When the smart night light provided in the utility model is used, the limit assembly 50 is set to limit the relative length of the wire 30 between the pressure sensing pad 10 and the bulb 20 to prevent the wire 30 from falling off at the joint between the pressure sensing pad 10 and the bulb 20. Specifically, the wire 30 with excess length is wound on the surface of the winding drum 43, and then the relative length of the loosened wire 30 is adjusted by rotating the winding drum 43 forward and reversely around the rotating shaft 42; in addition, the winding drum 43 can only drive the wire 30 to rotate forward to loosen the wire 30 originally wound on the winding drum 43, and the winding drum 43 has a reverse rotation. When the turning trend is, the position of the ratchet 51 is stuck by the pawl 52 to prevent the winding drum 43 from tightening the loosened wire 30; the torsion spring 60 arranged between the rotating shaft 42 and the winding drum 43 is used to automatically drive the winding assembly 40 to reset when the restriction of the limit assembly 50 on the winding assembly 40 is removed. Specifically, if the winding drum 43 is accidentally pulled, it drives the wire 30 to rotate around the rotating shaft 42 for a certain angle, causing the torsion spring 60 to be tightened. After the restriction of the ratchet 52 on the ratchet 51 is removed, the winding drum 43 is reversed and reset around the rotating shaft 42 under the action of the restoring force of the torsion spring 60.
