[0024] The artificial Christmas tree of the utility model reduces wiring and simplifies the circuit by arranging a wireless power supply device on the tree body.

[0025] Specifically, see Figure 1 The artificial Christmas tree of the utility model comprises a base 10, a tree unit 20, a wireless power supply unit 30 and a light set 40. The base 10 is set on the ground and supports the tree unit 20 extending upward. The wireless power supply unit 30 is arranged on the tree unit 20 in the up-down direction, and the light set 40 is hung on the tree unit 20 and electrically connected to the wireless power supply unit 30.

[0026] The tree unit 20 includes at least one tree assembly 21, and the tree assembly 21 includes a main rod 211, a mounting seat 212, and a branch 213. The main rod 211 is fixed above the base 10 and extends in the up-down direction. A plurality of mounting seats 212 are sleeved outside the main rod 211 and arranged in the up-down direction. A plurality of branches 213 are inserted circumferentially on each mounting seat 212, one end of the branch 213 is hinged to the mounting seat 212, and the other end can rotate around the axis in a direction away from or close to the main rod 211. The light group 40 is hung on the branch 213. The same light group 40 can be connected between different branches 213 and then connected to the wireless power-on unit 30, or a group of light groups 40 are hung on each branch 213, and each group of light groups 40 is electrically connected to the wireless power-on unit 30. Further, the number of the tree assembly 21 is more than two, and different tree assembly 21 are arranged in the up-down direction. In adjacent tree assemblies 21, the bottom of the main pole 211 of the upper tree assembly 21 is inserted into the top of the main pole 211 of the lower tree assembly 21, and the main pole 211 at the bottom is inserted into the base 10, so as to sequentially splice artificial Christmas trees of different heights.

[0027] The wireless power-on unit 30 includes a power supply wire 31, at least one wireless transmitting module 32 and at least one wireless receiving module 33. In the wireless power-on unit 30 located at the bottom, one end of the power supply wire 31 is close to the base 10 and electrically connected to the DC power supply 100, and the other end is electrically connected to the wireless transmitting module 32. The wireless transmitting module 32 and the wireless receiving module 33 are installed on the main pole 211 and are close to each other. The wireless receiving module 33 is electrically connected to at least one group of light groups 40 to power them. The wireless transmitting module 32 is provided with a wireless transmitting coil 321 and a transmitting module 322 electrically connected to the wireless transmitting coil 321, and the wireless receiving module 33 is provided with a wireless receiving coil 331 and a receiving module 332 electrically connected to the wireless receiving coil 331. When the DC power supply 100 is turned on and generates an AC signal through the oscillation circuit, the wireless transmitting coil 321 is energized and generates an alternating magnetic field. The wireless receiving coil 331 is affected by the alternating magnetic field generated by the wireless transmitting coil 321 and converts electromagnetic energy into electrical energy to power the light group 40. Since no cables are required between the wireless transmitting module 32 and the wireless receiving module 33, electrical energy can be transmitted as long as it is within the magnetic field range, thereby reducing the number of cables on the artificial Christmas tree and simplifying the wiring. In addition, in this embodiment, the wireless power-on unit 30 is configured to supply power to the light group 40. However, according to actual needs, other electrical devices on the artificial Christmas tree, such as motors, can also be electrically connected to the wireless receiving module 33, and the wireless power-on unit 30 supplies power to other electrical devices.

The power supply wire 31 of the lowest wireless power-on unit 30 is connected to the DC power supply 100. When the DC power supply 100 is turned on, the lowest wireless transmitting module 32 generates an alternating magnetic field, the lowest wireless receiving module 33 generates electrical energy, and supplies power to the wireless transmitting module 32 above it, and the wireless transmitting module 32 above it generates an alternating magnetic field, so that the upper wireless receiving module 33 generates electrical energy at the same time, and each wireless power-on unit 30 is powered on in turn, so that the light group 40 on the entire artificial Christmas tree lights up. Setting up multiple wireless power-on units 30 can facilitate setting circuits according to the locations of electrical equipment such as the light group 40, thereby reducing the length of cables.

[0029] Furthermore, the wireless transmitting module 32 and the wireless receiving module 33 in the same wireless power-on unit 30 are respectively located between two adjacent tree body components 21, wherein the wireless transmitting module 32 is located at the top of the lower main pole 211, and the wireless receiving module 33 is located at the bottom of the upper main pole 211. When the bottom of the upper main pole 211 is inserted into the top of the lower main pole 211, the wireless transmitting module 32 and the wireless receiving module 33 are close to each other, thereby reducing the number of required wireless power-on units 30.

[0030] Further, in one embodiment, the wireless power supply unit 30 is built-in, and the main rod 211 is a hollow cylinder. The wireless transmitting coil 321 and the wireless receiving coil 331 are respectively arranged inside the main rod 211, the wireless transmitting coil 321 is coiled around an axis extending up and down on the outside of the transmitting module 322, and the wireless receiving coil 331 is coiled around an axis extending up and down on the outside of the receiving module 332.

The outer wall of the main rod 211 is provided with a through hole 211A connected to the inside thereof, and the cable of the light group 40 can be connected to the inside of the main rod 211 from the outside through the through hole 211A. In this embodiment, the wireless power supply unit 30 also includes a connector 34, one end of which is electrically connected to the wireless receiving coil 331 through a cable, and the other end is located outside the main rod 211 and is threadedly connected to the cable connector of the light group 40.

[0031] In another embodiment, the wireless power supply unit 30 is external, and further includes two or more shells 35 with openings at one end, the shells 35 are sleeved on the outside of the main rod 211, and there is a gap between the inner wall and the outer wall of the main rod 211, the wireless transmitting coil 321 is wound around the axis extending up and down between the inner side of the lower shell 35 and the outer side of the lower main rod 211, the transmitting module 322 is arranged on one side of the wireless transmitting coil 321, and is located between the wireless transmitting coil 321 and the shell 35; the wireless receiving coil 331 is wound around the axis extending up and down between the inner side of the upper shell 35 and the outer side of the upper main rod 211, and the receiving module 332 is arranged on one side of the wireless receiving coil 331, and is located between the wireless receiving coil 331 and the shell 35. In this embodiment, the cross-sectional outer contour of the main rod 211 is circular, the shell 35 is wound around the outer side of the main rod 211, and a connecting hole 341 communicating with the interior thereof is provided on the shell 35. When in use, the openings of the upper shell 35 and the lower shell 35 are opposite to each other. After the two shells 35 are combined to form a box body, the wireless transmitting coil 321 and the wireless receiving coil 331 are sealed in the two shells 35, and the cable of the lamp group 40 is connected to the inside of the shell 35 through the connecting hole 351.

[0032] In addition, on the same artificial Christmas tree, external wireless power-on units 30 may be provided on some of the main poles 211 as needed, internal wireless power-on units 30 may be provided on other main poles 211, or all of the main poles 211 may be provided with external wireless power-on units 30, or all of the main poles 211 may be provided with internal wireless power-on units 30.
