Description

Technical Field

[0001] This utility model relates to the field of decorative Christmas tree technology, and in particular to an environmentally friendly and energy-saving Christmas tree. Background Technology

[0002] To achieve energy conservation, most existing Christmas tree decorations are equipped with solar panels. These panels convert solar energy into electrical energy, which then powers the LED lights inside the Christmas tree.

[0003] However, in existing technologies, solar panels are directly combined with decorative Christmas trees without being decorated or hidden, making the solar panels visually obtrusive and reducing the aesthetics and visual appeal of the decorative Christmas trees. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where solar panels reduce the aesthetics and visual appeal of decorative Christmas trees, and to propose an environmentally friendly and energy-saving Christmas tree.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design an environmentally friendly and energy-saving Christmas tree, including the Christmas tree body and also including:

[0007] An energy-saving decorative component includes a first hemisphere and a second hemisphere with an opening on one side. The openings of the first hemisphere and the second hemisphere are rotatably connected by a connecting shaft. The second hemisphere can be rotatably nested inside the first hemisphere. A solar panel is fixedly installed at the opening of the second hemisphere by a mounting bracket.

[0008] Preferably, a spline pin is provided at one end of the connecting shaft located inside the second hemisphere, so that when the connecting shaft rotates, the second hemisphere can be rotated along the connecting shaft through the spline pin.

[0009] Preferably, it further includes a rotary drive assembly, which includes a motor housing. The connecting shaft has a first slot at one end located on the outer side of the first hemisphere, and a second slot is formed around the connecting shaft on the outer end face of the first hemisphere. One end of the motor housing can be inserted into the interior of the second slot. A drive motor is fixedly installed inside the motor housing, and the output shaft of the drive motor is connected to the first slot in a transmission manner.

[0010] Preferably, a light sensor is nested on the outer end face of the second hemisphere, and the light sensor is used to control the start and stop of the drive motor.

[0011] Preferably, a brush bristle is installed on one side of the opening of the first hemisphere, and the end of the brush bristle slides in contact with the outer surface of the solar panel.

[0012] Preferably, a sealing gasket is nested at the opening of the first hemisphere, and the sealing gasket slides against the outer surface of the second hemisphere.

[0013] Preferably, the outer wall of the first hemisphere is provided with a drainage hole.

[0014] The environmentally friendly and energy-saving Christmas tree proposed in this utility model has the following advantages:

[0015] The first and second hemispheres can be used to conceal the solar panels, allowing the decorative balls on the Christmas tree to be integrated with the solar panels. In the dark, the first and second hemispheres rotate via a connecting shaft to form a spherical structure, enhancing the visual appeal. During the day, when there is ample sunlight, the first and second hemispheres rotate via the connecting shaft to form a hemispherical structure, allowing the solar panels to face the sunlight directly, thus achieving photoelectric conversion and energy saving.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0022] Reference Figure 1 , Figure 3An environmentally friendly and energy-saving Christmas tree includes a Christmas tree body 1 and an energy-saving decorative component. The energy-saving decorative component includes a first hemisphere 2 and a second hemisphere 3 with an opening on one side. The openings of the first hemisphere 2 and the second hemisphere 3 are rotatably connected by a connecting shaft 4. The second hemisphere 3 can be rotatably nested inside the first hemisphere 2. A solar panel 12 is fixedly installed at the opening of the second hemisphere 3 by a mounting bracket 11.

[0023] Furthermore, refer to Figure 4 A spline pin 5 is provided at one end of the connecting shaft 4 located inside the second hemisphere 3. When the connecting shaft 4 rotates, the second hemisphere 3 can be rotated along the connecting shaft 4 through the spline pin 5.

[0024] Furthermore, refer to Figure 3 , Figure 4 It also includes a rotary drive assembly, which includes a motor housing 8. A first slot 6 is provided at one end of the connecting shaft 4 located outside the first hemisphere 2. A second slot 7 is provided around the connecting shaft 4 on the outer end face of the first hemisphere 2. One end of the motor housing 8 can be inserted into the interior of the second slot 7. A drive motor 9 is fixedly installed inside the motor housing 8. The output shaft of the drive motor 9 is connected to the first slot 6 in a transmission manner.

[0025] Furthermore, refer to Figure 2 A light sensor 13 is nested on the outer end face of the second hemisphere 3. The light sensor 13 is used to control the start and stop of the drive motor 9. A control circuit board is also provided inside the motor housing 8. The drive motor 9 and the light sensor 13 are both electrically controlled through the control circuit board. A brush 16 is installed on one side of the opening of the first hemisphere 2. The end of the brush 16 slides in contact with the outer surface of the solar panel 12.

[0026] Furthermore, a sealing gasket 15 is nested at the opening of the first hemisphere 2, and the sealing gasket 15 slides against the outer surface of the second hemisphere 3. A drainage hole 14 is provided through the outer wall of the first hemisphere 2.

[0027] Working principle:

[0028] Reference Figure 3 In the figure, there are two sets of connecting shafts 4. The two sets of connecting shafts 4 are respectively placed at the left and right ends of the first hemisphere 2. Both sets of connecting shafts 4 have a spline pin 5 and a first slot 6 structure. The outer wall of the first hemisphere 2 is provided with a second slot 7 on the periphery of the two sets of connecting shafts 4. Therefore, in use, the motor housing 8 can be connected to any set of second slots 7, and the output end of the drive motor 9 can be connected to the first slot 6 for transmission. After the motor housing 8 and the second slot 7 are installed, the Christmas tree body 1 can be hooked on the hook 10 provided on the motor housing 8.

[0029] In one usage, the first hemisphere 2 and the second hemisphere 3 form a spherical structure in the initial state. The sealing gasket 15 is used to fill the gap between the first hemisphere 2 and the second hemisphere 3 to reduce liquid intrusion. However, this approach cannot completely prevent liquid intrusion. Therefore, a drain hole 14 for draining liquid is provided in the first hemisphere 2.

[0030] When the light sensor 13 receives sunlight, it transmits the light signal to the control circuit board recessed inside the motor housing 8. When the sunlight intensity exceeds the threshold set inside the control circuit board, the control circuit board controls the drive motor 9 to start. The output end of the drive motor 9 drives the connecting shaft 4 to rotate through the first slot 6. Since the connecting shaft 4 has a spline pin 5 at one end inside the second hemisphere 3, when the connecting shaft 4 rotates, it can drive the second hemisphere 3 to rotate through the spline pin 5. The second hemisphere 3 rotates accordingly until the combination of the first hemisphere 2 and the second hemisphere 3 forms a hemispherical structure, or the solar panel 12 faces the direction of direct sunlight. At this time, the solar panel 12 receives light and converts it into electrical energy. This electrical energy can power the LED lights installed in the first hemisphere 2 and the second hemisphere 3, and can also charge the battery installed in the second hemisphere 3 so that the battery can power the drive motor 9 and the LED lights when the light is poor.

[0031] While the second hemisphere 3 rotates, the bristles 16 can come into contact with the solar panel 12 and clean it. Since the Christmas tree is set up in winter, the bristles 16 can also brush away the snow on the surface of the solar panel 12. When the power generation of the solar panel 12 decreases, the second hemisphere 3 can be rotated and the light intensity can be re-determined by the light sensor 13. If the light sensor 13 determines that the light intensity is high, the drive motor 9 can be cycled to control the rotation of the second hemisphere 3, so that the bristles 16 can clean the solar panel 12.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
