Description

Technical Field

[0001] This utility model belongs to the field of timing lighting fixtures, and specifically relates to an electronic hourglass. Background Technology

[0002] A traditional hourglass is a timekeeping instrument consisting of two hollow glass spheres connected by a pipe. The time it takes for sand, which fills the upper sphere, to flow through the pipe into the lower sphere is measured, thus creating a constant timekeeping system. Furthermore, combining the hourglass with decorative lighting fixtures can achieve the effect of timed illumination, making it convenient for various occasions.

[0003] For example, Chinese patent document CN216243994U, published on April 8, 2022, discloses a pressure-sensitive hourglass sleep aid lamp, comprising: an hourglass body, including an upper hourglass body and a lower hourglass body connected to each other, with flowing sand moving between the upper and lower hourglass bodies; a lower cover is provided on the side of the lower hourglass body away from the upper hourglass body, and a light is provided on the lower cover, located inside the lower hourglass body; a pressure sensor for detecting the pressure on the lower cover is connected to the lower cover, and the light is electrically connected to the pressure sensor; a wireless Bluetooth speaker for playing preset audio is provided in the lower cover, with the switch, indicator light, and sound outlet of the wireless Bluetooth speaker all located on the side of the lower cover, and the wireless Bluetooth speaker is electrically connected to the pressure sensor; wherein the brightness of the light and the volume of the wireless Bluetooth speaker decrease as the pressure detected by the pressure sensor increases. This utility model can automatically reduce the brightness of the light as the user gradually falls asleep, providing a better sleep aid effect.

[0004] However, the timekeeping function in the aforementioned hourglass is achieved by the flow of sand within the hourglass itself. The brightness of the light and the volume control of the wireless Bluetooth speaker are also achieved through the interaction of the sand flow and a pressure sensor within the hourglass. The timekeeping method of the hourglass based on sand is not very accurate. Moreover, the brightness of the light and the volume control of the wireless Bluetooth speaker are also achieved through the interaction of sand and a pressure sensor, resulting in a relatively complex structure and high cost, which is not conducive to the widespread adoption of hourglasses.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] A traditional hourglass is a timekeeping instrument consisting of two hollow glass spheres connected by a pipe. The time it takes for sand, which fills the upper sphere, to flow through the pipe into the lower sphere is measured, thus creating a constant timekeeping system. Furthermore, combining the hourglass with decorative lighting fixtures can achieve the effect of timed illumination, making it convenient for various occasions.

[0033] For example, Chinese patent document CN216243994U, published on April 8, 2022, discloses a pressure-sensitive hourglass sleep aid lamp, comprising: an hourglass body, including an upper hourglass body and a lower hourglass body connected to each other, with flowing sand moving between the upper and lower hourglass bodies; a lower cover is provided on the side of the lower hourglass body away from the upper hourglass body, and a light is provided on the lower cover, located inside the lower hourglass body; a pressure sensor for detecting the pressure on the lower cover is connected to the lower cover, and the light is electrically connected to the pressure sensor; a wireless Bluetooth speaker for playing preset audio is provided in the lower cover, with the switch, indicator light, and sound outlet of the wireless Bluetooth speaker all located on the side of the lower cover, and the wireless Bluetooth speaker is electrically connected to the pressure sensor; wherein the brightness of the light and the volume of the wireless Bluetooth speaker decrease as the pressure detected by the pressure sensor increases. This utility model can automatically reduce the brightness of the light as the user gradually falls asleep, providing a better sleep aid effect.

[0034] However, the timekeeping function in the aforementioned hourglass is achieved by the flow of sand within the hourglass itself. The brightness of the light and the volume control of the wireless Bluetooth speaker are also achieved through the interaction of the sand flow and a pressure sensor within the hourglass. The timekeeping method of the hourglass based on sand is not very accurate. Moreover, the brightness of the light and the volume control of the wireless Bluetooth speaker are also achieved through the interaction of sand and a pressure sensor, resulting in a relatively complex structure and high cost, which is not conducive to the widespread adoption of hourglasses.

Through dual-light source synchronous compensation technology, it achieves a lighting effect of brightness shift and constant total brightness. It can not only complete accurate timing, but also simulate the use scenario of an hourglass with sand.
