Abstract
The utility model discloses a magnetic induction switch for a casing of an audio book for children, which is designed to solve the problem that a power supply can be opened or closed when the audio book for children is opened or closed. The utility model adopts the method of the combination of a magnetic latch and a dry reed pipe. The utility model comprises a small magnet, a box cover, a bottom plate, a small iron plate, the dry reed pipe and a power supply control circuit, wherein the small magnet is fixed at the external end of the box cover, the small iron plate and the dry reed pipe are orderly installed on the bottom plate, and the dry reed pipe is connected with the power supply control circuit. When the magnetic latch is opened or closed, the utility model leads to the action of the dry reed pipe to control the on-off of a power supply. By using a simple method, the utility model solves the problem of opening and closing of the latch and the power supply of the box cover of the audio book for children, which results in more convenient opening and closing of the audio book for children. The utility model is used for children teaching toys.
Description
Technical field
The utility model is a kind of switching device of children voice material, be a kind of be the casing breech lock, be again the magnetic induction switch of power supply, be the automatic switch of electronic instruction toy.
Background technology
All need to open the breech lock of casing before known children voice material uses, press mains switch again, finishing using also needs the powered-down switch.Operating just has more two steps always, also is a difficult point to the child, and presses switch for a long time, also may cause certain part loose contact.Casing is taked the closed type structure mostly, the open and close of bolt-lock type floatless switch control machine shell.Latch switch often causes the complexity in the use for various reasons for child user, and extra mains switch has increased the difficulty of using undoubtedly.
Summary of the invention
The purpose of this utility model provides a kind of children voice material casing magnetic induction switch.This automatic switch is a kind of magnetic latch of casing, is again mains switch.Children as long as open magnetic latch simply gently, are about to power connection, operation that need not be special in use.
The utility model is achieved in that children voice material casing magnetic induction switch, it is characterized in that: comprising: small magnet, lid, collet, small iron plate, tongue tube, power control circuit; Described small iron plate and tongue tube are installed on collet side by side.Described tongue tube is connected with the circuit of control power supply.
The children voice material external form is chest of picture usually, is made up of collet and lid, in the outer end of lid, fix a small magnet, fixed a slice small iron plate on the correspondence position of collet, its effect is the magnetic line of force closure that makes small magnet when lid is closed, and plays the effect of the tight lid of door bolt.Fixed a tongue tube on the next door of small iron plate, small iron plate and tongue tube are installed on collet side by side.When lid is closed, the tongue tube closure, control circuit ends, and power circuit cuts out.Magnetic latch is as long as firmly just can open gently, and when lid was opened, magnet was away from tongue tube, and tongue tube is opened, and the control circuit conducting makes power supply opening.Lid is automatic energized when opening, and it is very convenient to operate, and is fit to the needs of child teaching toy.
The beneficial effects of the utility model are: use a kind of simple method to solve the breech lock and the mains switch problem of children voice material lid, make the children voice material switch more convenient.
Below in conjunction with accompanying drawing or embodiment the utility model is described further.
Description of drawings
Fig. 1 is the position view of the utility model on children voice material;
Fig. 2 be the utility model when the lid closed condition in Fig. 1 the A-A cutaway view Amplified image;
Fig. 3 be the utility model when the lid closed condition in Fig. 2 the B-B cutaway view.
Specific embodiment
Fig. 1,2,3 is position view and lid the cutaway view when closing of children voice material casing magnetic induction switch on the children voice material casing.Among the figure: 1 small magnet, 2 lids, 3 collets, 4 small iron plates, 5 tongue tubes, 5.1 tongue tube lead-out wires.
Children voice material external form in the present embodiment is as a chest, form by collet 3 and lid 2, outer end at lid 2, fix a small magnet 1, on the correspondence position of collet, fixed the small iron plate 4 of a slice U type, the purpose that is made into the U type is the magnetic line of force closure that makes small magnet when lid is closed, and plays the effect of the tight lid of door bolt, as shown in Figure 3.Fixed a tongue tube 5 on the next door of small iron plate 4, the lead-out wire 5.1 of tongue tube 5 is connected on the circuit of a control power supply.Control circuit ended when the control circuit logical relation was designed to reed switch conduction, power-off; Control circuit turn-on when tongue tube ends, power supply opening.Like this when lid is closed, tongue tube 5 conducting under the effect of magnet, the control circuit that tongue tube lead-out wire 5.1 connects ends power-off.Magnetic latch is as long as firmly just can open gently, and when lid 2 was opened, small magnet 1 was away from tongue tube 5, and tongue tube 5 has not had magneticaction and ended control circuit conducting, power connection.Lid is automatic energized when opening, and it is very convenient to operate, and is fit to the needs of child teaching toy.
