Description

[Detailed explanation of the idea] The present invention relates to an ultrasonic humidifier.

Generally, an ultrasonic humidifier humidifies the water tank by generating water mist through the vibration of a vibrator that faces the inside of the water tank.
When the humidifier body falls over or the water tank becomes empty, the vibrator inside the water tank operates under no load, causing heat generation and damage.

Therefore, conventionally, a float equipped with a magnet is equipped with a magnetically sensitive switch such as a reed switch that opens and closes by the movement of the float to detect the water level and protect the vibrator. Since the part and the installation part of the magnetically sensitive switch are constructed separately,
The positional relationship between the float and the magnetically sensitive switch is likely to vary due to the installation work, and as a result, there may be cases where the magnetically sensitive switch does not operate.

The present invention was devised in view of the above points, and it makes it easy to install the float and the magnetically sensitive switch, and prevents variations in the positional relationship between the float and the magnetically sensitive switch due to the installation work, and always performs normal humidification. This is to make it easier.

To explain the present invention with reference to the drawings below, the main body 1 of the ultrasonic humidifier consists of a water tank 5 placed on top of a machine room 4 which houses a blower 2, an oscillation circuit 3, etc. A main water tank 7 in which a humidifier 6 is arranged is formed, and an auxiliary water tank 9 is arranged in parallel with the main water tank 7 and communicates with the main water tank 7 through a communication hole 10 and serves as the water tank of this humidifier. Water is allowed to fall from the ice tank 5 via the valve device 8 and is temporarily stored therein.

Further, a rectifying cylinder 12 having a hollow cylindrical part 11 hanging down into the water tank 7 is disposed at the upper part of the main water tank 7, and a blow-off cylinder 14 in which a blow-out port 13 is formed is rotatable on the rectifying cylinder 12. It is provided for.

The auxiliary water tank 9 is formed so as to supply humidifying water to the main water tank 7 in a timely manner by supplying water from the water tank 5, and also to determine the water level of the main water tank 7, and is equipped with a float 15 and a magnetically sensitive switch 16 at appropriate locations inside. The installed mounting member 17 is provided.

The mounting member 17 includes an L-shaped mounting portion 18 and a cylindrical insertion portion 19 disposed at the upper end of the vertical portion of the mounting portion 18 so as to be parallel to the horizontal portion and having a closed end. The vertical part of the mounting part 18 is brought into contact with the side wall of the auxiliary water tank 9, and the horizontal part is placed on the bottom wall, and the insertion part 19
The opening end thereof is extended to protrude through the side wall, and a threaded portion 20 is formed in this protruding opening end to which a nut 21 is screwed from the outside.

Therefore, this mounting member 17 is disposed at one corner of the auxiliary water tank 9 and is fastened to the side wall by screwing with a nut 21.

The float 15 is equipped with a magnet 22 at the top and a support 23 movable in all directions, such as a chain, at the bottom, and the mounting portion 18 is attached so that it floats movably within a predetermined range.
It is equipped with a pivot on the horizontal part.

Therefore, the movement of the float 15 is not limited to only the vertical direction, but also moves in all directions, so that even when the humidifier main body 1 is tipped over, it is reliably moved away from the magnetically sensitive switch 16.

The magnetically sensitive switch 16 closes its contacts by the magnetic force of the magnet 22 when the float 15 has a sufficient water level and is upright. is led out from the open end and connected to the oscillation circuit 3.

Reference numeral 25 designates a removable protective cover provided at a suitable position on the installation member 17 so as to protect the float 15.

The configuration of the present invention is as described above, and the float 15 and the magnetically sensitive switch 16 installed to detect the level of humidifying water in the main water tank 7 bulge out on the mounting part 18 of the float 15 and the mounting part. Since the magnetically sensitive switch 16 and the magnetically sensitive switch 16 mounting insertion portion 19 formed by the above method are respectively mounted on the integrally formed mounting member 17, variations in the positional relationship between the float 15 and the magnetically sensitive switch 16 due to assembly work are prevented. can.

In addition, by forming the insertion part 19 for installing the magnetically sensitive switch 16 to bulge above the mounting part 18 of the float 15,
Since the float 15 can be installed to be movable not only in the vertical direction but also in all directions, the float 15 can reliably move away from the magnetically sensitive switch 16 and cut off the power even when the humidifier main body 1 is tipped over.

As described above, according to the present invention, it is possible to facilitate the installation work of the float and the magnetically sensitive switch, prevent variations in the positional relationship due to the installation work of the float and the magnetically sensitive switch, and furthermore, it is possible to freely swing the float. Since the humidifier is installed in the humidifier, the vibrator can be reliably stopped not only when the water level drops, but also when the humidifier body falls over and tilts in any direction, allowing normal humidification to be performed at all times.

In addition, since the horizontal part of the mounting part is placed on the bottom wall of the aquarium and the vertical part is brought into contact with the side wall, it can be positioned when fixing, and the insertion part is made to protrude through the side wall, and a threaded part is provided here. It can be tightened from the outside with a nut, and the lead wire can be led out from the open end, making it very simple.

In particular, when the aquarium installation parts (mounting part and insertion part) are integrally molded, it is necessary to provide extra work space for leading out the lead wires and installing the switch, but according to the present invention, the magnet and switch The positional relationship between the mounting part and the insertion part can be easily achieved by integrally molding the mounting part and the insertion part, and since the installation member and the water tank are separate parts, the work of mounting the switch and leading out the lead wires can be done very easily.

Incidentally, the above-mentioned effects can be obtained similarly if the installation member is provided not only in the auxiliary water tank but also in the water tank that determines the water level of the main water tank.
