Abstract

The utility model discloses a waterproof remote controller, which can be used for the remote control of an electric appliance in a bathroom or the remote control of an electric appliance used outdoors. A control circuit of the remote controller is mounted in a waterproof plastic shell; a remote-control control chip and eight capacitive touch inductive keys are arranged on the control circuit; one 3V button cell supplies a power supply to the circuit; and one shock inductive switch is connected with an input pin of the control chip. The waterproof remote controller also comprises an infrared transmitting tube used for transmitting an infrared remote control signal. The waterproof plastic shell is divided into an upper casing and a lower casing, and a rubber sealing ring is arranged at a joint between the upper casing and the lower casing to prevent water seepage. A circular cell cover is also arranged on the lower casing, and a sealing ring is also arranged at a joint between the cell cover and the lower casing. The whole remote controller adopts a full-hermetic design, and when the waterproof remote controller is in use, a corresponding remote control instruction can be triggered so long as a finger slightly touches a key position on a plastic panel of the remote controller.

Description

The waterproof telepilot

Affiliated technical field

The utility model belongs to a kind of electronic control circuit, relates to a kind of waterproof telepilot, is used for the device of remote control home appliance.

Background technology

At present, its keyswitch of domestic electrical equipment remote controller that the most generally uses partly is generally conducting resinl formula switch, does not possess waterproof requirement.Along with the household electrical appliance kind is more and more, occurred in a lot of bathrooms or the electrical equipment of outdoor use.Especially the electrical equipment that uses of bathroom, because humid environment, the switch of some electrical equipment is contained in the bathroom and is absolutely unsafe, and does not possess water-proof function and also damages easily if use a teleswitch.

The utility model content

The technical matters that the utility model will solve is: a kind of hand-held remote control unit of all-sealed structure is provided, can prevents that the water that sprays is penetrated on the circuit board of telepilot.Power consumption is extremely low during the telepilot standby.Therefore this telepilot need its internal circuit be in dormant state to reduce power consumption, once staff will get into mode of operation from dormant state after picking up telepilot automatically when not using.Need a vibration inductive device to detect picking up of staff.

The technical scheme that addresses the above problem is: the utility model is provided with the control chip of low-power consumption and the capacitance type touch key that is connected with the control chip input end, is used for the remote control input.An infrared transmitting tube that is connected with the control chip output terminal is used to launch telecommand.The vibration sensing switch that is connected with the control chip input end in addition is used for control chip is waken up from power-down mode.The junction of telepilot shell has O-ring seal to prevent that water is penetrated on the circuit of the inside.A pin of the vibration sensing switch here is connected with the control chip input end, and connects the pull-up resistor of a 3M ohm.Another pin earth terminal.Its inner contact of vibration sensing switch is a spring structure; Be generally off-state, vibrations a little will make its inner spring contact connect, as long as staff rocks the telepilot vibration switch and will connect; Control chip input pin level is changed, controller is waken up from power-down mode.Use the capacitance touch induction as remote keying, capacitance type touch key is that the circle on the remote control circuit plate is covered the copper plane, and it is connected with the control chip input end through a resistance.The circle of capacitance type touch key is covered the copper plane and is contacted with the bottom of telecontrol panel; Telecontrol panel is the waterproof plastic plate of 1 millimeter to 5 millimeters of thickness; Because capacitance type touch key can be sensed the approaching of finger being separated with under the situation of certain thickness plastic plate, therefore can accomplish the circuit of telepilot is sealed in the enclosure fully.The utility model is because all-sealed structure, thereby well solved domestic electrical equipment remote controller in the bathroom or the waterproof problem of outdoor use, makes the remote control household electrical appliances promptly convenient safety again that becomes.

Embodiment

U1 is a control chip among Fig. 2, and SW1 is a vibration sensing switch, and DS1 is an infrared-emitting diode, and button 1 to button 8 covers copper face for the circle of capacitance touch induction.

In Fig. 2, CR2025 is the 3V button cell, for control chip provides power supply.Vibration sensing switch SW1 is connected with control chip input end PC0; When telepilot during by static placement vibration sensing switch be normal ON state; The PC0 port is a high level; Surpass 2 fens kind control chip U1 and will get into power-down mode if continue high level, at this moment the power consumption electric current of entire circuit will can be above 1 microampere.When staff is picked up telepilot or rocked telepilot, vibration switch closes in the time of will opening when rocking, and the PC0 port will detect the level of height conversion, and control chip input pin level is changed, and wakes controller up the entering mode of operation from power-down mode.In mode of operation, controller every at a distance from 125 milliseconds will the run-down touch induction keyboard, will start infrared-emitting diode emission infrared remote control through the PC1 port and instruct once detected the touch sensible button.
