Abstract
Description
[Technical field]
[0001] [Background technology]
[0002] There is no cheap switch that has a simple structure where the switch is turned on when the door is opened and not activated when the door is closed, and the switch is turned on when the door is opened and not activated when the door is closed. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Real whole Showa 48-099872 [Patent Document 2] Patent Publication 54-162182 Summary of the Invention [Problem to be solved by the invention]
[0004] When using the toilet, there is a switch next to the door that can sometimes be forgotten to be turned off, and although there are some LED lights that can be turned off with a timer function using proximity switches or body temperature sensors, there is still a small electricity cost for constantly being on standby. There is a sense of uncertainty about when the timer will go off. [Means for solving the problem]
[0005] We propose a device that uses magnets to turn on the light when the toilet door is opened, does not activate the switch when the toilet door is closed after entering the toilet, and turns off the light when the door is opened when leaving the toilet. There is no need to worry about forgetting to turn off the switch, and there is no need to worry about the light going out while using the toilet, which gives a sense of security, lowers electricity bills, reduces CO2 emissions, and eliminates the need to forget to turn off the switch. The structure is simple and easy to install. Effect of the Invention
[0006] When you use this switch in the bathroom, you don't have to worry about lighting. You can also turn on the ventilation fan and indicate when it is in use with a light. [Brief description of the drawings]
[0007] [Figure 1] Main body 8 is molded from plastic and a commercially available switch is fixed in place. Coil spring 4 is set on the slide shaft and inserted into main body 8, then stopper 5 is attached and inserted into main body 8. Slide shaft 3 and commercially available switch 7 are connected with a string. Make sure there is no slack in the string and that no force is applied to coil spring 4. Set magnet 2 on the inside of the toilet door. Coil spring 4 is a weak coil spring 4 that ensures that slide shaft 3 and magnet 2 are firmly attached when the toilet door is closed.
[0008] [Diagram 2] When the door is opened, the slide shaft 3 is attracted by the magnet 2, and the cord of a commercially available switch is pulled, activating the switch.
[0009] [Diagram 3] This shows the state when the door is closed. When the door is closed, the slide shaft 3 is attracted to the magnet 2, but since there is little movement when it is attracted, it does not activate the switch. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0011] When many people use the toilet, if you open the toilet door and then close it, the lights may not turn on or off properly. This can be fixed by opening and closing the door again, but this is a drawback of this switch. [Industrial Applicability]
[0012] The light may not turn on properly. You can fix this by opening and closing the door again, but I think this is very useful for people who have limited access to the toilet or who understand this device. If it is waterproof, this device can also be used as a bathroom light switch. [Explanation of symbols] 1 Door 2. Magnet 3 Slide shaft 4 Coil spring 5 Stopper 6 Connecting cord 7. Commercially available switches that can be turned on and off with a string 8. Main body for mounting slide shaft 3 and commercially available switch 7 9 Lid to cover the main body
Claims
1. This is a device that turns the switch ON and OFF when the door is opened, and does not work when the door is closed. When the toilet door is opened, the switch turns ON, the light comes on, and the switch remains ON even when you enter the toilet and close the door. When you leave the toilet, the switch turns OFF when you open the door. The switch remains OFF even when the door is closed.
2. The switch is turned on and off using the attraction of a magnet.
3. We use a commercially available switch with a string attached, which turns the switch ON when the string is pulled and OFF when the string is pulled.
4. At the same time as lighting the toilet when you are using it, you can also turn on the ventilation fan and light the notice board at the entrance to the toilet to indicate when it is in use.
