Abstract: A single smart health device able to monitor all physiological aspects of a human body includes a body fluid detection module, a temperature detection module, an electrocardiogram detection module, and a control module. The body fluid detection module tests and detects amounts of biological substances in body fluids. The temperature detection module detects a temperature of the human body. The electrocardiogram detection module detects a heart rate of the human body. The control module is electrically connected to the body fluid detection module, the temperature detection module, and the electrocardiogram detection module, and obtains the detected amounts of biological substances, the detected temperature, and the detected heart rate.

Abstract: A convenient self-locking blood pressure cuff facilitating one-handed use by a user taking his own blood pressure includes a cuff belt, a casing assembly, and a self-locking structure. The self-locking structure is received in the casing assembly. The self-locking structure includes a core shaft, a locking assembly, and a pressing assembly. The core shaft is slidably connected to the casing assembly. The locking assembly and the pressing assembly are wrapped around the core shaft. The locking assembly can rotate when a free end of the cuff belt moves with respect to the casing assembly. The locking assembly can further press against the cuff belt when the core shaft slides in the casing assembly. The pressing assembly presses against the locking assembly to prevent the locking assembly from rotating back.

Abstract: A clip-on strap assembly includes a watch strap with a groove and two mounting holes, a base disposed in the groove and including a midpoint connecting portion, two movable members movably on the base and located on opposite sides of the connecting portion, two snap hooks disposed on ends of the movable members, two elastic members disposed between the movable members and the connecting portion, and two pressing members disposed on the movable members and accommodated in the two mounting holes. The pressing members can bear against the elastic members. The snap hooks can engage with or be disengaged from the two buckles. The watch strap is clipped to or unclipped from the watch head merely by only pressing the two pressing members, facilitating the replacement of the watch strap.

Abstract: A rear cover assembly structure of an air purifier allows for rapid opening and demounting of a rear cover and includes a housing, the rear cover, a hooking mechanism, and a magnetic connection mechanism. The rear cover can be assembled on or detached from the housing by the hooking mechanism and the magnetic connection mechanism. The hooking mechanism includes a groove set on the housing and a shaft set on rear cover. The shaft being set in the groove or separated from the groove respectively locks or unlocks the hooking mechanism. The magnetic connection mechanism includes a magnetic assembly set on the housing and a metal sheet set on the rear cover, the metal sheet is attracted to the magnetic assembly. The metal sheet is set on the housing by a fixed structure of the housing.

Abstract: An icon display structure includes a display panel including a silkscreen interlayer, a diffusion sheet, and a light source. The diffusion sheet includes a light transmission zone. The silkscreen interlayer includes a silkscreen icon and defines a hollow icon. The silkscreen icon is aligned with the hollow icon and appears directly on the display panel. The light transmission zone of the diffusion sheet is aligned with the silkscreen icon and the hollow icon. The light source is positioned behind the diffusion sheet. The light source emits light and the light transmits through the light transmission zone and the hollow icon to light up the silkscreen icon on the display panel.

Abstract: An electronic device includes an imaging light assembly including a display panel, a circuit board, a light source, and a light cover. The light source is mounted and electrically coupled to the circuit board. The light cover is mounted to a rear surface of the display panel and covers the light source. The light source emits light to the light cover. The light cover includes at least one projection lens located between the light cover and the display panel. The at least one projection lens focuses the light emitted by the light source and projects the focused light to the display panel. The focused light projected to the display panel projects an image of a design of the projection lens.

Abstract: A filter cleaning mechanism includes a sliding rail, a filter, a dust box, a cleaning device, and a driver. The filter is mounted to the sliding rail. The dust box is mounted to a bottom of the sliding rail. The cleaning device is mounted in front of the filter and above the dust box. The cleaning device includes a cleaning brush and a screen. The driver is mounted to a side of the sliding rail and is electrically coupled to the cleaning device. The driver moves up and down along the sliding rail. The cleaning brush and the screen move along with the driver up and down the sliding rail. The driver drives the cleaning brush to brush the filter. The screen blocks the front of the filter while the cleaning brush brushes the filter.
