Description

  The present invention relates to a fall detection switch, and more particularly to a fall detection switch that can reduce the cost of materials by controlling the conduction or disconnection of a micro switch using only a pressing member.

  As a conventional fall detection switch, for example, in the new model No. M256575 “Fall detection switch structure” in China, the fall detection switch includes a large sphere, a small sphere, a groove, and a micro switch. The large sphere and the small sphere are accommodated in the groove, and the large sphere is stacked above the small sphere. The groove body is positioned above the microswitch and presses the small sphere to the switching plate of the microswitch through the opening of the groove body. In use, the conventional fall detection switch is mounted in an electric device (for example, an electric heater), and the micro switch is connected to a power supply circuit. The axial direction of the groove is perpendicular to the horizontal ground. The small sphere receives the gravity of the large sphere and presses the switching plate downward, and the switching plate presses the microswitch activator downward, thereby causing the microswitch and the power source to be pressed. Since an open circuit is formed with this circuit, the operation of the electric device can be started.

When the electric device is pushed down or tilted, the groove body is inclined with respect to the horizontal ground, so that the large sphere slides toward one side and comes out of the small sphere. Since the weight of the small sphere cannot push the starter down, a closed circuit is formed between the microswitch and the circuit of the power source, and the electric device stops operating. It is possible to automatically enter a short circuit state (see, for example, Patent Document 1).
Taiwan new model number M256575

  The conventional fall detection switch has the following problems. For example, the activator cannot be pressed by the switching plate unless the small sphere receives gravity below the large sphere. As described above, since the conventional fall detection switch has to control the operation or stop of the electric device using the operation of two spheres, the material cost is relatively high. Have. Thus, the conventional fall detection switch as described above must be further improved.

  The present invention was devised in view of such problems, and the object of the present invention is to reduce the cost of the material by controlling the microswitch to be conductive or nonconductive using only the pressing member. An object of the present invention is to provide a fall detection switch that can be reduced.

  The first object of the present invention is to form an open circuit or a closed circuit between the micro switch and the power source by pressing the micro switch using the pressing member or by releasing it from the micro switch. Therefore, an object of the present invention is to provide a fall detection switch that can reduce the cost of materials.

In order to achieve the above object, the fall detection switch according to the present invention is as follows. That is,
A shell, a microswitch, and a pressing member are included. A retaining member is formed on the inner peripheral wall surface of the shell, and the first housing member and the second housing member are partitioned inside the shell by the retaining member. A through-hole for communicating the first housing space and the second housing member is formed in the latching member, and the first housing space is formed downward from the inner peripheral wall surface of the shell body toward the center of the through-hole. An inclined surface is formed so as to approach. The microswitch is provided in the second housing space of the shell. The micro switch includes a touching portion. The pressing member is housed in the first housing space of the shell and is formed so as to be positioned on the inclined surface of the latching member.

  Referring to FIG. 1, when the fall detection switch according to the embodiment of the present invention is used in an electric device (for example, an electric heater, a drinking water device, an electric fan, and a lighting device), the electric device is tilted to cause danger. Can be prevented. The fall detection switch includes a shell 1, a micro switch 2, and a pressing member 3. The shell body 1 is provided with a main body portion 11, a bottom seat 12, and an upper lid 13, and the one bottom seat 12 and the upper lid 13 are respectively fixed to the bottom end and the upper end of the main body portion 11 corresponding to the shape of the main body portion 11.

  The main body portion 11 is preferably formed of a circular sleeve, and a latch member 111 and a coupling member 112 are formed on the main body portion 11, and the latch member 111 is formed on the inner peripheral wall surface of the main body portion 11. The main body 11 is partitioned from a first housing space 113 and a second housing space 114 that are vertically adjacent to each other, and the hooking member 111 is provided with a through hole 1111 and an inclined surface 1112, and the through hole 1111 is hooked in the axial direction. The inclined surface 1112 passes through the stopper member 111, and is formed so as to extend from the inner peripheral wall surface of the shell 1 to the center and down of the through hole 1111 in the hook member 111, and the hook member 111 further enters the first accommodation space 113. Formed to approach. The coupling member 112 is provided so as to extend from the outer peripheral wall of the shell 1, and the coupling member 112 selectively includes a plurality of screw holes, so that the fall detection switch 2 is connected to the inside of the electric device by the coupling member 112. Can be screwed on.

  Referring again to FIG. 1, the bottom seat 12 of the embodiment of the present invention is preferably constructed by assembling two half members 121 to correspond to each other, and the fine member 2 is sandwiched between the two half members 121. By doing so, the microswitch 2 can be mounted on the bottom seat 12. The microswitch 2 is fixedly installed in the second housing space 114 of the main body 11 by the bottom seat 12, and the microswitch 2 is connected to a circuit of a power supply (not shown) to control the operation state of the electric device. One of the microswitches 2 is close to the through-hole 1111 is provided with a tactile part 21, an elastic member 211 and an activation member 212 are formed on the tactile part 21, one end of the elastic member 211 is fixed to the microswitch 2, The activation member 212 is positioned below the elastic member 211 and formed so as to contact the elastic member, whereby the activation of the micro switch 2 can be controlled.

  Referring to FIG. 1 again, the pressing member 3 according to the embodiment of the present invention is received in the first receiving space 113 and is formed to abut against the latching member 111. The pressing member 3 is selectively spherical. It can be made of a nearly polygonal solid, and in the embodiment of the present invention is made of a metal sphere. A part of the pressing member 3 passes through the through hole 1111 and enters the second accommodation space 114, is brought into contact with the elastic member 211, and presses the touching portion 21 downward due to the gravity of the pressing member 3. Further, the outer diameter of the pressing member 3 is smaller than the inner diameter of the first accommodating space 113, and further, a distance of a distance is formed between the outer peripheral wall surface of the pressing member 3 and the inner peripheral wall surface of the main body 11, thereby making the shell body 1 minute When the inclination occurs, the pressing member 3 can immediately roll along the inclined surface 1112 in the direction of the inclination and can be detached from the tactile portion 21.
