[Problems to be solved by the invention]
However, the conventional waterproof remote control device has the following problems.
a. With regard to the waterproof structure of the battery compartment, it is easy to open and close when replacing the battery with the face seal as in (1), but it is necessary to hold down the seal face evenly, and the waterproof performance is easy depending on the deformation of the outer box There was a problem of being lost.
[0005]
b. In addition, the structure of the battery housing part of (2) and (3) is excellent in waterproof performance regarding deformation of the outer box, etc., but when replacing the battery, it is possible to remove the lid that pushes in the O-ring or packing. There is a problem that it is difficult and it is difficult to attach the O-ring or the packing so as not to be damaged by pushing or screwing the lid.
[0006]
c. Next, as for the waterproof structure of the infrared transmitter, as shown in (4), the outer periphery of the cylindrical infrared transmitter and the outer box are closely attached with an O-ring or packing to form a waterproof structure. Since the infrared transmitter is exposed to the outside, the infrared transmitter is easily moved by a user or the like, and there is a problem that the waterproof performance is impaired because a gap is formed between the packing and the outer box. It was. In addition, since the outer box incorporates a control board inside, it is divided into two exterior materials that divide the widest surface and surface of the outer box, and the O-ring or packing contact surface is on this joint line. If it is provided, there is a problem that the waterproof performance is likely to be further lowered.
[0007]
d. As for the waterproof structure of the infrared transmitter of (5), since the light emitting part cover and the outer box are joined by ultrasonic welding, it is not easy to assemble, and the light emitting part cover needs to have a predetermined thickness and strength. There was a problem of becoming.
[0008]
e. Regarding the waterproof structure of the infrared transmitter of (6), a large member that covers one end of the outer box with a bottomed cylindrical cap is required, and the sealing surface also covers the entire circumference of the outer box, so that the outer box is waterproof by deformation. Since the performance is easily lost, and the outer box cannot avoid the occurrence of a joining line on the surface overlapping the cap as described in d), there is a problem that the waterproof performance is inferior.
In addition, when joining by ultrasonic welding in the outer box, there was a problem that the burrs that had melted in the joining line protruded to the contact surface of the O-ring or packing, including the case of (4).
[0009]
The present invention solves the above-mentioned conventional problems. The battery housing part is excellent in waterproof performance, the battery can be easily replaced, and the infrared transmitter part is easily assembled and waterproof. The object is to provide an excellent waterproof remote control device.
