[0033] Figure 1 This is a schematic diagram of the structure of a touch column wax of the utility model. Figure 2 This is a cross-sectional view of the shell of a touch column wax of the utility model. Figure 3 This is an exploded view of a touch sensing element and a circuit board of a touch column wax of the utility model. Figure 4 This is a schematic diagram of the structure of a base of a touch column candle of the utility model. Figure 5 This is a control circuit schematic diagram of a touch sensing element of a touch column wax according to the utility model, such as Figure 1-5As shown, a touch column candle of a preferred embodiment is shown, including a shell 1, a lamp holder 2, a touch sensing element 3, a circuit board 4 and a base 5. The shell 1 is a cylindrical structure with an opening at the bottom and is made of pure wax material. The lamp holder 2 is arranged at the top of the shell 1. The touch sensing element 3 is a circular ring structure and is coaxially bonded to the inner wall of the top of the shell 1, and the inner ring of the touch sensing element 3 extends downward with two contacts 31. The circuit board 4 is arranged below the touch sensing element 3 and is electrically connected to the lamp holder 2. The circuit board 4 has two interfaces 41, and the two contacts 31 are respectively welded at the two interfaces 41 to electrically connect the circuit board 4 to the touch sensing element 3. When a human body touches the top of the shell 1 to the area where the touch sensing element 3 is located, the touch sensing element 3 transmits a sensing signal to the circuit board 4 to open and close the lamp holder 2. The base 5 is arranged at the bottom opening of the shell 1, and a battery (not shown in the figure) electrically connected to the circuit board 4 is installed on the base 5.

[0034] In this embodiment, when in use, by touching or approaching the area where the touch sensing element 3 is located on the top of the shell, the touch sensing element 3 sends a sensing signal to the circuit board 4 to turn on the lamp head 2. When the sensing area on the top of the shell is touched or approached again, the touch sensing element 3 again sends a sensing signal to the circuit board 4 to turn off the lamp head 2.

[0035] In this embodiment, the shell is made of pure wax material, so that the simulation of the candle is more realistic and the user's viewing experience is improved. At the same time, the touch sensing element 3 is directly bonded to the top inner wall of the shell. Since the shell is made of pure wax material, the influence on the sensing sensitivity of the touch sensing element 3 is reduced.

[0036] In this embodiment, the touch sensing element 3 and the circuit board 4 are electrically connected by welding to improve the signal transmission stability between the two.

[0037] Preferably, the two contacts 31 are symmetrically distributed on two sides of the touch sensing element 3 , and the circuit board 4 is distributed along the radial direction of the touch sensing element 3 .

[0038] Furthermore, as a preferred embodiment, the touch sensing element 3 is a metal sheet.

[0039] Further, as a preferred embodiment, the touch sensing element 3 is copper foil.

[0040] Specifically, Figure 5As shown, since the human body can be a conductor, it is regarded as one plate of a capacitor, and the touch sensing element 3 is the other plate of the capacitor. When the hand approaches or holds the area where the touch sensing element 3 is located, the capacity of the capacitor will increase, and an impedance will be generated at this time. After detection and comparison by the detection circuit, the signal is sent to the control chip U2 on the circuit board 4 for judgment and processing, and the control chip U2 outputs a high level to turn on the transistor Q1 on the circuit board 4. After the control chip U1 on the circuit board 43 obtains a low level, it outputs a pulse wave, and the lamp head 2 is turned on and lit. Conversely, when the hand approaches or touches the area where the touch sensing element 3 is located on the top of the shell 1 again, the charge of the capacitor will increase, and an impedance will be generated, causing the sensor vibration circuit inside the control chip U2 to generate a signal. After the signal is compared and amplified by the detection circuit, the signal is input into the control chip U2 for judgment and processing. The control chip U2 outputs a high level to turn on the transistor Q1. After the control chip U1 obtains a low level, the output of the pulse wave is stopped, and the lamp head 2 is turned off.

[0041] Furthermore, as a preferred embodiment, a switch 6 is provided at the bottom of the base 5, and the switch 6 is electrically connected between the circuit board 4 and the battery to control the on / off of the circuit between the circuit board 4 and the battery. When the lamp is not in use, the circuit between the battery and the circuit board 4 is disconnected by the switch 6 to avoid accidental touching of the sensing area to cause the light to turn on, thereby reducing unnecessary waste of battery power.

[0042] Furthermore, as a preferred embodiment, the switch 6 is a hand-push switch 6, which is an existing conventional accessory, and its principle and structure are not described in detail here.

[0043] Furthermore, as a preferred embodiment, the bottom of the base 5 has a battery slot, and the battery is installed in the battery slot.

[0044] Furthermore, as a preferred embodiment, a detachable battery cover 7 is mounted on the notch of the battery slot.

[0045] Furthermore, as a preferred embodiment, the battery cover 7 is connected to the notch of the battery slot via a snap-fit ​​structure.

[0046] Furthermore, as a preferred embodiment, the circuit board 4 and the battery, the battery and the switch 6, and the switch 6 and the circuit board 4 are all connected via wires 8.

[0047] Furthermore, as a preferred embodiment, the touch sensing element 3 is bonded to the top inner wall of the housing 1 by glue.

[0048] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
