Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of simulation candle, specifically relates to an improved inductive electronic candle. BACKGROUND

[0002] In some specific scenarios, in order to reduce fire hazards, reduce carbon dioxide emissions, while taking into account the convenience and safety of use, the traditional real candle is gradually replaced by the electronic simulation candle with similar appearance. The LED lamp is used as the light source inside the electronic simulation candle, which has basic lighting function and can be designed and developed to have diversified functions such as observation and entertainment, like electronic flash candle, music candle and simulated kerosene lamp, etc., to meet the use requirements of people in different scenarios.

[0003] For example, the Chinese utility model patent "Electronic simulation flame head and electronic simulation candle" with patent number 201920402400.3 (publication number CN209386167U) contains a simulation flame head body, which encapsulates a first light emitter inside. In the powered state, the control chip can control the LED chip to be partially or fully lit, thereby presenting a dynamic flame burning effect on the simulation flame head body. However, since the power switch is arranged at the bottom of the base, in order to perform the switching operation, the electronic candle must be held as a whole to complete the operation, which is relatively cumbersome. Moreover, since the candle body is made of wax material, the user's hand may feel greasy after holding, which affects the user's experience to some extent.

[0004] In view of the above problems, there is also an electronic candle that does not need to be held to quickly control its light-emitting state. For example, the Chinese utility model patent "Electronic candle with double control mode" with patent number 202322562674.8 (publication number CN20870796U) includes a base, an outer shell, and a simulation flame head with a first light emitter. The outer shell is installed on the base, and the simulation flame head is exposed from the top of the outer shell. The base is equipped with a power supply for the first light emitter and a PCB board for control. By setting a touch switch on the outer surface of the simulation flame head exposed from the top of the outer shell, the user only needs to touch the touch switch with his hand to easily control the opening and closing of the first light emitter of the simulation flame head, effectively avoiding the inconvenience of having to hold the entire electronic candle to operate the bottom control switch, and also reducing the problem of hand greasiness caused by holding the wax outer shell.

[0005] However, this improved product is not perfect. The touch switch for human control in this product is exposed, and the metal touch switch is exposed on the outer surface of the simulation flame head, which affects the aesthetics of the electronic candle to some extent.

[0030] The improved induction electronic candle of the present application will be further described in detail below with reference to the accompanying drawings.

[0031] Figures 1 to 3 The improved induction electronic candle of the present application will be further described in detail below with reference to the accompanying drawings.

[0032] The improved induction electronic candle of the present application will be further described in detail below with reference to the accompanying drawings. Figures 1 to 3As shown in Embodiment 1, the candle body 1 includes an outer shell 11 and a metal sleeve 12. The outer shell 11 is made of wax material to mimic the appearance of a real candle. The metal sleeve 12 is installed inside the outer shell 11, and its internal space forms a battery compartment 1b. The inner sidewall of the lower end of the metal sleeve 12 is machined with an internal thread 12a. The simulated flame head 2 has an installation chamber 2c inside. The touch electrode 2b1 of the touch-sensitive switch 2b is vertically installed in the installation chamber 2c. The touch electrode 2b1 has a spiral spring structure, which can improve the touch sensitivity and also make it easy to remove and position. It is also less likely to shake inside the simulated flame head 3. The light source 2a is a multi-color LED module, which is installed below the touch electrode 2b1. The battery 3 is selected with appropriate specifications to match the battery compartment 1b. The PCB control board 4 integrates a light source driving circuit and a mode control module. The light source driving circuit is used to drive the light source 2a, and the mode control module is electrically connected to the touch-sensitive switch 2b to switch the light emission mode of the light source 2a.

[0033] In addition, depending on the actual light emission requirements, there can be only one light emission body 2a or multiple light emission bodies 2a. Each light emission body 2a can emit light of different colors. By controlling the touch-sensitive switch 2b, multiple light emission bodies of different colors can emit light in turn or at the same time.

[0034] The metal spring 4a on the PCB control board 4 is used to contact the inner wall of the metal sleeve 12 to ensure stable circuit connection. The bottom cover 5 is provided with a connecting part 5b, and the outer periphery of the connecting part 5b is machined with an external thread 5b1, which cooperates with the internal thread 12a of the metal sleeve 12 to achieve a detachable connection; the outer periphery of the connecting part 5b is also formed with a conductive sheet 5a, and a groove 5c is opened on the lower end face of the bottom cover 5. The control switch 6 is installed in the groove 5c, and its pressing part 6a protrudes from the bottom of the groove 5c. The height of the pressing part 6a is lower than the depth of the groove 5c to prevent the control switch from being accidentally activated when the electronic candle is placed normally.

[0035] The connection and assembly process of each component in Example 1 is as follows: (Refer to...) Figure 2 and Figure 3As shown, first, place the PCB control board 4 into the control cavity 1a inside the candle body 1, so that the metal spring 4a holds it against the inner wall of the metal sleeve 12, completing the initial fixing of the PCB control board 4 and the preparation for circuit connection. Place the battery 3 into the battery compartment 1b formed by the metal sleeve 12, ensuring that the battery is installed firmly and the positive and negative terminals are connected correctly. Connect the touch-sensitive switch 2b and the light-emitting element 2a to the PCB control board 4 through wires. The wires are led out from inside the simulated flame head 2, pass down through the wire hole 1c at the top of the candle body 1, and connect to the corresponding interface of the PCB control board 4. Install the simulated flame head 2 on the top of the candle body 1, ensuring that the installation is firm and the appearance is flat. Finally, align the connecting part 5b of the bottom cover 5 with the lower end of the metal sleeve 12, rotate the bottom cover 5 so that the external thread 5b1 and the internal thread 12a fit tightly until it is installed in place. At this time, the conductive piece 5a is in good contact with the metal sleeve 12, and the control switch 6 is electrically connected to the PCB control board 4. The entire electronic candle assembly is complete.

[0036] The working principle of the touch-sensitive switch in Example 1 is as follows: The touch electrode 2b1 of the touch-sensitive switch 2b is the sensing component of the capacitive touch switch. When a human touches or approaches the outer surface of the simulated flame head, the human electric field will interact with the touch electrode 2b1. Since the human body itself is a conductor, the proximity of the human body will cause the electric field distribution around the touch electrode 2b1 to change, resulting in a change in the capacitance value of the touch electrode 2b1. This capacitance change is detected by the circuit inside the touch-sensitive switch 2b, thereby generating an electrical signal. This electrical signal is transmitted to the PCB control board 4 through the wire. After receiving the signal, the mode control module on the PCB control board 4 controls the light source driving circuit according to the preset program to realize the control of the opening, closing or light emission mode switching of the light-emitting body 2a.

The upper shell 13 has a cylindrical shape, and the base 14 is located at the bottom of the upper shell 13. A simulated flame head 2 is installed on the top of the upper shell 13. Inside the simulated flame head 2, there is a touch electrode 2b1 of a touch-sensitive switch 2b and a light-emitting element 2a. The touch electrode 2b1 is also a spiral spring structure, and the light-emitting element 2a is a multi-color LED module. The battery 3 is placed in the battery box 7a of the base 14 to power the electronic candle. The PCB control board 4 is installed on the base 14 and integrates a light source driving circuit and a mode control module for controlling the light-emitting mode of the light-emitting element 2a and driving it to emit light. The base 14 has a battery box 7a for holding the battery 3; the base 14 also integrates a control switch 6, which is electrically connected to the PCB control board 4 to realize the conduction or disconnection of the control circuit.

[0040] The connection and assembly process of each component in Example 2 is as follows: Install the PCB control board 4 on the base 14, and electrically connect the control switch 6 to the PCB control board 4. Place the battery 3 into the battery box 7a, ensuring that the battery 3 is installed correctly and the positive and negative terminals are connected correctly. Connect the touch-sensitive switch 2b and the light-emitting element 2a to the PCB control board 4 through wires. The wires are led out from inside the simulated flame head 2, extend downwards along the inside of the candle body 1 to the base 14, and connect to the corresponding interface of the PCB control board 4. Install the simulated flame head 2 on the top of the candle body 1, ensuring that the installation is firm and the appearance is harmonious. Finally, connect the bottom of the candle body 1 to the base 14, ensuring a tight connection so that the entire electronic candle forms a complete structure. The working principle of the touch-sensitive switch in Example 2 is the same as that in Example 1.
