Technical Field

[0001] This utility model relates to the field of hourglass technology, specifically an hourglass with a built-in windmill. Background Technology

[0002] An hourglass, also known as a sand clock, is a device for measuring time. It consists of two hollow glass spheres connected by a narrow tube. Time is measured by the time it takes for sand to flow from the top hollow glass sphere through the narrow tube into the bottom hollow glass sphere. Once all the sand has flowed into the bottom hollow glass sphere, the hourglass can be inverted to measure the remaining time.

[0003] A search revealed a Chinese utility model patent with publication number CN218197703U, which discloses a new type of hourglass craft. According to its description, when the sand grains fall inside the hourglass, the windmill can rotate with them. The entire piece is made of glass or plastic, making it more beautiful and interesting.

[0004] However, the hourglass in the above patent has the following problems: (1) the windmill cannot emit light during rotation, resulting in poor decorative effect and no lighting; (2) the hourglass is filled with sand grains, which are smoothly stacked inside the hourglass after falling, making it impossible for the grains to explode, resulting in poor decorative effect.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 1-3 An hourglass with a built-in windmill includes a base 1 and an hourglass body 2 mounted on the base. The top of the base 1 is provided with an installation groove 3, and the end of the hourglass body 2 is inserted into the installation groove 3. A magnet 4 is provided in the upper part of the base 1. Iron sand 5 is contained in the hourglass body 2. When the magnet is installed on the base, the iron sand will be attracted to the magnet when it falls, and will explode or form a flower-like shape to enhance the decorative effect.

[0027] A U-shaped rod 6 is connected to one end of the hourglass body 2. A windmill 7 is rotatably connected to the U-shaped rod 6. The windmill 7 is located below the neck of the hourglass body 2. When iron sand falls, it hits the fan blades, thereby driving the windmill to rotate. Each fan blade 8 of the windmill 7 contains an LED 9. A power supply module is located in the base 1. After the hourglass body 2 is installed in the mounting slot 3, all the LEDs 9 and the power supply module form a closed circuit.

[0028] Specifically, the fan blade 8 has a first channel 10, and the U-shaped rod 6 has a second channel 11 connected to the first channel. A first conductive sheet 12 is connected to the bottom surface of one end of the U-shaped rod 6. The first conductive sheet 12 is located outside the hourglass body 2. The LED bead 9 is electrically connected to the first conductive sheet 12 after passing through the first channel 10 and the second channel 11 via a wire. The power supply module includes a control board 13 and a battery 14 installed in the base. The base 1 has a third channel 15, and a second conductive sheet 16 is connected above the third channel 15. The second conductive sheet 16 is electrically connected to the control board 13 and the battery 14 after passing through the third channel 15 via a wire. After the hourglass body 2 is installed in the mounting slot 3, the first conductive sheet 12 and the second conductive sheet 16 are electrically connected. At this time, the LED bead 9, the first conductive sheet 12, the second conductive sheet 16, the battery 14, and the control board 13 form a closed circuit, thereby supplying power to the LED bead. All the LED beads here can be connected in series or in parallel.

[0029] The top surface of the base 1 is provided with a switch 17, which is electrically connected to the control board 13. The LED beads can be turned on or off by using the switch.

[0030] A battery cover 18 is snapped onto the bottom of the base 1. The battery cover facilitates battery replacement.

[0031] In summary, when the iron filings fall, they strike the windmill's blades, causing the windmill to rotate. As the windmill rotates, the LEDs emit light, providing both illumination and a decorative effect. By installing magnets on the base, the falling iron filings are attracted to the magnets and may even explode, further enhancing the decorative effect.

[0032] Example 2

[0033] Based on Example 1, the LED beads 9 inside each leaf 8 are of different colors. Neon lamps can be used here, and each neon lamp has a different color, resulting in a variety of colors and further enhancing the decorative effect.
