Abstract: A split-type range hood having guiding hook grooves for a pressure dispersion tray includes a range hood body and the pressure dispersion tray. The range hood body includes a chassis. A smoke collecting guide tank upwardly recesses from a bottom of the chassis. An inner wall of the smoke collecting guide tank has two guiding hook grooves that are spaced apart from each other. Each guiding hook groove has a trapezoidal opening and a left narrow slit and a right narrow slit extending outwardly from a bottom edge of the trapezoidal opening. A distance between the left narrow slit and the right narrow slit is defined as a length of each guiding hook groove. A frame of the pressure dispersion tray has two mounting hooks that are spaced apart from each other, and are capable of being movably snapped onto the guiding hook grooves.

Abstract: A split-type range hood having an optimal configuration of a smoke-collecting case includes a housing and the smoke-collecting case. The housing has an upper wall, a lower wall, and an intake port. The smoke-collecting case covers on the intake port. The smoke-collecting case has an outer box and a covering lid. The outer box is fixed to a periphery of the intake port. The covering lid is fixedly connected to a top portion of the outer box. The covering lid has an outlet port that fluidly connects the smoke-collecting case to the intake port of the housing. A height of the smoke-collecting case is between 5 cm and 7 cm.

Abstract: A flipper-type electronics cabinet includes a cabinet body, two first sliding rails, two second sliding rails, two third sliding rails, a carrying tray, a door plate, an accommodating tray, and a circuit controlling device. The circuit controlling device is disposed in the cabinet body and includes a controlling interface, a controller, a master switch circuit, a first switch circuit, and a second switch circuit. The controlling interface includes a master switch key, a first switch key, and a second switch key. The controller enters an operation or standby mode according to the master switch signal received. When the controller enters the standby mode, the master switch circuit is switched-off, and when the controller enters the operation mode, the master switch circuit is switched-on. When the controller enters the operation mode, the controller is used to respectively control the first and second switch circuits to be switched-on or switched-off.

Abstract: A drawer-type electronics cabinet includes a cabinet body, two sliding rails, a carrying tray, a door plate, and a circuit controlling device. The circuit controlling device is disposed in the cabinet body and includes a controlling interface, a controller, a master switch circuit, a first switch circuit, and a second switch circuit. The controlling interface includes a master switch key, a first switch key, and a second switch key. The controller enters an operation or standby mode according to the master switch signal received by the controller. When the controller enters the standby mode, the master switch circuit is switched-off, and when the controller enters the operation mode, the master switch circuit is switched-on. When the controller enters the operation mode, the controller is used to respectively control the first and second switch circuits to be switched-on or switched-off according to the received first and second switch signals.
