Description

Technical Field

[0001] The utility model belongs to the field of hand dryers, and particularly relates to an intelligent hand dryer. Background Art

[0002] Hand dryers are common sanitary cleaning devices on the market. After washing their hands, users place their hands under the air outlet of an automatic hand dryer, which automatically delivers comfortable warm air to quickly dry and dehumidify their wet hands. Patent publication number CN106175547A discloses a hand dryer comprising a base, a housing, a motor, a heating element, a fan, and a control circuit board. The fan includes a hub and cylindrical blades with a first circular port and a second circular port. The fan's air outlet faces the housing's air outlet, and the hub is located on the first port of the fan. The heating element is positioned near the second port of the blade, and the motor is located on the other side of the fan relative to the heating element. The motor's output shaft is connected to the hub and drives the hub to rotate. Existing hand dryers only have a single outlet, requiring them to be mounted entirely on a fixed wall, making installation inconvenient. Furthermore, the air outlet of existing hand dryers is large, resulting in poor airflow and poor air distribution.

[0012] Preferably, a pressure plate for fixing the wall-mounted back panel and the bottom panel is provided between the wall-mounted back panel and the bottom panel, and the pressure plate is fixedly mounted on the bottom panel.

[0013] When the hand dryer needs to be wall-mounted, first secure the wall-mounted back panel to the wall; then install the second wiring socket on the mounting base and connect the second wiring socket to an external power source; a pressure plate is provided on the bottom plate, with a gap between the pressure plate and the bottom plate; when the hand dryer is mounted on the wall-mounted back panel, the top of the wall-mounted back panel is inserted into the gap between the pressure plate and the bottom plate; then, the hand dryer is locked with anti-theft screws, so that the hand dryer can be securely and firmly mounted on the wall-mounted back panel; when the hand dryer is mounted on the wall-mounted back panel, the first wiring socket and the second wiring socket are plugged together, thereby energizing the air outlet motor and the control circuit board; here, the first wiring socket and the second wiring socket are matched male and female plugs, and the two automatically snap together when plugged in. Then, when the user's hands approach the sensing component, the air outlet motor will automatically work.

[0014] Preferably, the built-in wiring seat is fixedly mounted on the base plate, and a second wire pressing buckle is provided on the base plate adjacent to the built-in wiring seat.

[0015] When the hand dryer needs to be directly fixed on the wall, the base plate is fixed on the wall, and then the cover and the base plate are connected; at the same time, the built-in wiring socket is connected to the external power supply. When the user's hands are close to the sensing component, the air outlet motor can automatically work.

[0016] Compared to existing technologies, this utility model has the following advantages: 1. By integrating the wall-mounted backplate and baseplate, the hand dryer can be mounted independently, making installation and removal much easier. 2. The hand dryer is locked in place by anti-theft screws, preventing direct removal of the hand dryer from the wall-mounted backplate; unlocking the screws requires a special wrench, making it safer and more reliable. 3. The hand dryer can be directly fixed to the wall and then connected to an external power source via the first wiring socket, providing greater versatility. BRIEF DESCRIPTION OF THE DRAWINGS
