Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an apparatus with a cartridge tank that supplies liquid to a liquid storage part of an apparatus main body so as to maintain a constant liquid level.

[Technical background of the invention]

Conventionally, in this type of cartridge tank-equipped equipment, such as an ultrasonic humidifier, the humidifier body is provided with a water storage portion having a push-up protrusion and a flat tank mounting portion, while a water inlet is provided with a water inlet that approaches and separates from the push-up protrusion. A cartridge tank equipped with a valve device that is opened and closed by the tank device is removably mounted on the tank device section. In this cartridge tank, when a gap is created between the water surface and the water supply port due to a drop in the water level in the water storage section when the valve device is opened, air flows into the cartridge tank from the water supply port, and the internal A constant water level is maintained by supplying water to the water storage section.

[Problems with background technology]

However, in the above conventional configuration, when carrying the humidifier with the cartridge tank mounted in order to change the installation location of the humidifier, if the humidifier is tilted, the water level in the water storage section will drop. Because of this fluctuation, there is a problem that a gap is created between this water surface and the water supply port of the cartridge tank, and the water in the cartridge tank is supplied to the water storage section above the normal water level, and sometimes water overflows from the water storage section. It was a good idea to put it away. Further, particularly in the case of ultrasonic humidifiers, when the water level in the water storage section rises above the normal water level, the ultrasonic vibrator is subjected to an unnecessarily large load, resulting in a reduction in the amount of atomization and a reduction in humidification capacity.

[Purpose of invention]

The present invention was developed in view of the above circumstances, and its purpose is to prevent the liquid in the cartridge tank from being supplied to the liquid storage section when the main body of the device is carried with the cartridge tank mounted. The purpose of the present invention is to provide equipment with a cartridge tank that can prevent this.

[Summary of the idea]

In order to achieve such an object, the present invention has a valve device that is opened and closed by contacting and separating from a push-up protrusion protruding from the device body, and when the valve device is opened, the liquid inside is drained from the liquid stored in the device body. A device equipped with a cartridge tank for supplying liquid to the device so as to maintain a constant liquid level, a support portion is provided on a part of the upper surface of the device body, and a support portion is provided horizontally away from the support portion and further than the support portion. A support member is provided in the lowering portion of the device so as to be able to move up and down, and whose lower end is in contact with the installation surface of the device main body, and the cartridge tank is placed between the support portion and the upper end of the support member. When the device main body is lifted, the cartridge tank tilts while pushing down the support member due to its own weight, thereby separating the valve device from the push-up protrusion.

[Example of idea]

An embodiment in which the present invention is applied to an ultrasonic humidifier will be described below with reference to the drawings. 1 is the humidifier body installed on the installation surface A, 2 is the body case of this humidifier body 1, which has an open upper and lower surface as shown in FIG. It is divided into upper and lower sections by a partition wall 3. The partition wall 3 has a recessed water storage section 4 on the left side thereof, and a push-up protrusion 5 protrudes from the right side of the water storage section 4. Further, a flat support part 6 is formed adjacent to and on the right side of the water storage part 4 in a bulging position higher than the water storage part 4, and furthermore, a slope part 7 is formed by sloping downward from this support part 6 to the right side. There is. Although not shown, an ultrasonic transducer is disposed at the bottom of the water storage section 4. Reference numeral 8 denotes an atomization chamber cover detachably attached to the water storage section 4 so as to cover the upper part thereof, and a mist discharge port 9 is provided at the upper part. Reference numerals 10 and 11 indicate handles formed on the left and right side walls of the main body case 2 (only the left side is shown in FIG. 1);
is a bottom plate provided on the lower surface of the main body case 2.
Reference numeral 12 denotes a rod-shaped support member provided inside the main body case 2 so as to be able to move up and down. penetrates and protrudes upward,
The lower part penetrates the bottom plate 11 and projects downward.
The lower end of the support member 12 is in contact with the installation surface A of the humidifier main body 1, and in this contact state, the upper end is located at approximately the same height as the support part 6 of the main body case 2. 13 is a stopper provided on the support member 12 to define the limit of upward movement of the support member 12; and 14 is an insertion hole 15 formed in the partition wall 3 to allow the support member 12 to pass therethrough.
A flexible cap is provided to seal the support member 12 and cover the upper part of the support member 12.
By inserting the upper part into the flexible cap 14 with some pressure, it is prevented from coming off downward. On the other hand, 16 is a cartridge tank in the shape of an oblong rectangular container, and a short cylindrical water supply port 17 is formed protruding from the bottom of the tank near the left end as shown in FIG.
The water supply port 17 is non-porous except for the water supply port 17. 18
is a cap having a substantially double cylindrical shape, in which the inner cylindrical part 19 is inserted into the water supply port 17 of the cartridge tank 16, and the outer cylindrical part 20 is inserted into the water supply port 1.
7 and is removably attached to the water supply port 17. A valve stem support part 22 having an insertion hole 21 is horizontally suspended in the radial direction in the middle part of the inner cylindrical part 19, and a valve stem 23 is inserted through the insertion hole 21 so as to be vertically movable. There is. A bowl-shaped valve body 24 is attached to the upper end of the valve stem 23, and a spring 25 is interposed between the lower flange 23a and the valve stem support 22 to keep the valve stem 23 downward at all times. The valve device 26 is constituted by the valve device 26. The cartridge tank 16 configured in this manner is removably mounted between the support part 6 of the main body case 2 and the upper end of the support member 12. It is supported at the left side of the center and supported by the support member 12 at a position near the right end. When the cartridge tank 16 is placed substantially horizontally between the support portion 6 and the upper end of the support member 12, the push-up protrusion 5 is placed on the valve stem 23 as shown in FIG. The valve stem 2 is in contact with the lower end flange 23a of the
3 is pushed up, thereby opening the valve device 26 and supplying water from the cartridge tank 16 so that the water level in the water storage section 4 of the humidifier body 1 is maintained at a constant water level B. That is, to maintain a constant water level, when the water level in the water storage section 4 falls below the lower end surface of the cap 18, a gap is created between the water surface and the lower end surface of the cap 18, and air flows into the cartridge tank 16 from the cylindrical section 19. The water in the cartridge tank 16 is supplied into the water storage part 4 accordingly, and the water level in the water storage part 4 rises, and when the lower end surface of the cap 18 is sealed by the water surface, the water flows into the cartridge tank 16. This is carried out by repeating an operation in which the inflow of air is stopped and the water supply to the water storage section 4 is stopped. On the other hand, when the cartridge tank 16 is taken up from the humidifier main body 1 in order to replenish water to the cartridge tank 16, the lower end flange 23a of the valve stem 23 separates from the push-up protrusion 5. As shown, the valve stem 23 is moved downward by the biasing force of the spring 25, and the valve body 24 closes the upper end opening of the cylindrical portion 19. This brings the valve device 26 into the closed state and prevents water from flowing from the cartridge tank 16. The spill is stopped.

Next, the operation of the above configuration will be explained. For example, when carrying the humidifier main body 1 in order to change the installation location of the humidifier main body 1, place the cartridge tank 16 on the humidifier main body 1 by placing your hands on the handles 10 on both the left and right sides of the main body case 2. Lift it from installation surface A while holding it. Then, the cartridge tank 16 is
The center of gravity of this is located approximately at the center in the left-right direction, and the support portion 6
Since it is located more to the right, its own weight pushes down the support member 12 located at the right end of the cartridge tank 16, and it tilts around the support part 6 so that the right side descends and the left side rises (fifth (see figure). Then, the portion of the cap 18 at the left end of the cartridge tank 16 and therefore the valve stem 23 of the valve device 26 are separated from the push-up protrusion 5, thereby closing the valve device 26 and preventing any further water in the cartridge tank 16. The outflow of will be stopped. Therefore, even if the water level in the water storage section 4 fluctuates due to a slight inclination of the humidifier main body 1, the valve device 26 of the cartridge tank 16 is closed, so that the water in the cartridge tank 16 flows into the water storage section 4. will not be supplied to Therefore, the amount of water in the water storage section 4 will not increase, and water will not overflow from the water storage section 4. Then, if you carry the humidifier body 1 and install it at a different installation location,
The lower end of the support member 12 comes into contact with the installation surface of another installation location and is pushed up, and the right end of the cartridge tank 16 is pushed up and returns from the tilted state to the horizontal state, thereby causing the push up. The valve stem 23 comes into contact with the portion 5 and returns the valve device 26 to the open state. In this case, the water level in the water storage section 4 is maintained at the water level B before carrying the humidifier main body 1, so even if the ultrasonic vibrator is activated to start humidifying operation, the ultrasonic vibrator will not exceed the required level. Normal humidification operation can be performed without any load being applied and without deteriorating humidification capacity.

The present invention is not limited to ultrasonic humidifiers, but can be applied to devices equipped with cartridge tanks, such as kerosene stoves, and can be implemented with appropriate modifications within the scope of the invention.

[Effect of idea]

As is clear from the above description, the present invention provides a support part on a part of the upper surface of the device main body, and the device main body is provided in a part horizontally away from the support part and lower than the support part. A support member penetrating through the device so as to be vertically movable and having its lower end in contact with the installation surface of the device main body is provided, and a cartridge tank having a one-way valve device is placed between the support member and the upper end of the support member. Accordingly, when the main body of the device is lifted, the cartridge tank tilts while pushing down the support member due to its own weight,
The valve device closes when the valve device is moved away from the push-up protrusion of the device body, so that when the device body is carried with the cartridge tank placed on it, the liquid in the cartridge tank can be removed from the device. This has an excellent practical effect in that it can prevent the liquid from being supplied to the liquid storage part of the main body and the liquid level in the liquid storage part rising.
