detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Fig. 1 and Fig. 2, the device for adding water to the ventilator humidifier of this embodiment includes a water supply container 1 for supplying water to the ventilator humidifier and a water storage container 2 positioned above the water supply container 1, the water supply container 1 A water inlet 101 is provided, and the water inlet 101 communicates with the water storage container 2 . The water supply container 1 is provided with a buoyancy switch assembly 3 for opening or closing the water inlet 101 to control the water level in the water supply container 1 . The water in the water storage container 2 is added into the water supply container 1 through the water inlet 101. When the water level in the water supply container 1 is higher than the set range, the buoyancy switch assembly 3 closes the water inlet 101 to stop adding water; When the water level in the water supply container 1 is lower than the set range due to the consumption of the humidifier of the ventilator, the buoyancy switch assembly 3 opens the water inlet 101 to add water to the water supply container 1 until the water level in the water supply container 1 rises again Out of the set range, so that the water level in the water supply container 1 can be kept within the set range. Therefore, when the water adding device for the ventilator humidifier is in operation, it does not need to manually control the switch, it only needs to add water to the water storage container 1 regularly, and the water level of the water supply container 2 can be automatically controlled by the buoyancy switch assembly 3 to be at a set value. The height range has the advantages of high degree of automation and low labor intensity.

In this embodiment, the water supply container 1 includes a bucket body 4 and a bucket cover 5 . The buoyancy switch assembly 3 comprises a slide bar 31, a buoyancy component 32 and a mounting seat 33 fixed on the bung 5, the slide bar 31 is slid on the mounting seat 33 along the vertical direction and can make its upper end blocked or closed by sliding up and down. Away from the water inlet 101 , the buoyancy component 32 is connected to the lower end of the slide bar 31 , and the buoyancy component 32 in this embodiment is an inflatable airbag. The inflatable airbag can float on the water surface and drive the slide bar 31 to slide up and down with the rise and fall of the water level. The upper end seals the water inlet 101, and the water storage container 2 stops adding water to the barrel body 4; when the water in the barrel body 4 continues to flow out, the inflatable air bag will drop along with the drop of the water level, and at the same time drive the slide bar 31 to slide downward until the barrel body 4 continues to flow out. When the water level of body 4 was lower than the set range, the upper end of slide bar 31 was away from water inlet 101, and water inlet 101 was opened, and water storage container 2 added water to staving 4 again.

Further, the upper end of the sliding rod 31 is tapered, and can be partially inserted into the water inlet 101 and closely contact with the surrounding edges of the water inlet 101 , thereby improving the sealing performance when sealing the water inlet 101 . The mounting seat 33 is L-shaped, and the L-shaped mounting seat 33 includes a vertical extension and a lateral extension. A sliding hole is provided, and the sliding rod 31 is slidably arranged in the sliding hole. The L-shaped mount 33 has a simple structure and is easy to manufacture.

In this embodiment, the sliding rod 31 is threaded and connected with a limit bolt 311 . The limit bolt 311 can not only prevent the slide rod 31 from slipping out of the slide hole, but also facilitate the installation and disassembly of the slide rod 31 .

In this embodiment, the bucket body 4 and the bucket cover 5 are connected by threads, which have the advantages of easy disassembly and good sealing performance.

In this embodiment, the water storage container 2 includes a cylindrical body 6 that penetrates up and down, and the lower end of the cylindrical body 6 is sealed and connected to the bung 5 to form a water storage cavity, that is, the cylindrical body 6 and the bung 5 together constitute the water storage container 2 The water storage cavity is beneficial to improve the compactness of the structure, save materials and reduce the production cost. Further, the upper end cover of the cylinder body 6 is provided with a sealing cover 7 . When adding water in the cylinder body 6, the sealing cover 7 is opened, and after adding water, the sealing cover 7 is closed to prevent impurities from falling into the water of the cylinder body 6 and causing pollution.

The above descriptions are only preferred implementations of the present utility model, and the protection scope of the present utility model is not limited to the above-mentioned embodiments. For those skilled in the art, the improvement and transformation obtained under the premise of not departing from the technical concept of the utility model should also be regarded as the protection scope of the utility model.
