Technical Field
[0001] This utility model relates to the field of ventilator technology, and mainly to a ventilator water tank adapter valve that is compatible with ordinary plastic bottles. Background Technology
[0002] The water tank of the ventilator is a water storage mechanism and an important component of the ventilator. The humidified water not only reduces the side effects of nasal dryness (such as nasal congestion and bleeding), but more importantly, it reduces nasal resistance, effectively ensuring the stability of the pressure inside the mask, improving treatment efficacy and adaptability, which is very important for patients who wear the ventilator for long-term treatment.
[0003] Commercially available ventilators are bulky, inconvenient to carry, and unsuitable for home use. Therefore, this applicant filed a prior application (CN221384797U) disclosing a portable humidifier with a water-saving mechanism, including an upper shell, a bottom shell, and an adapter. A waterproof plate is installed within the cavity formed by the upper and bottom shells. The humidifier has an adapter with internal threads, allowing a water bottle to be installed on it, simplifying the ventilator's structure, reducing its size, and making it easier to carry. However, this portable humidifier requires an inverted water bottle for water intake, meaning the bottle is placed upside down on top of the humidifier. To prevent water from leaking out, the humidifier is typically installed upside down, with the bottle upright, to connect it to the bottle. This installation method is cumbersome and may damage the humidifier. Furthermore, when the device is used upright, water may overflow. Utility Model Content

[0031] Please refer to the following for details. Figure 1-5 A ventilator water tank adapter valve adapted to a common plastic bottle 3 includes a main body 1. The main body 1 has an inlet 11 inside. One end of the main body 1 has a threaded structure on its inner wall. This threaded structure is adapted to the common threaded plastic bottle 3 commonly found in the consumer market. That is, the plastic bottle 3 can be connected to the adapter valve through the threaded connection. The connection method is simple. The other end of the main body 1 has two opposite outlets 12. The liquid in the plastic bottle 3 enters from the inlet 11 and flows out from the outlets 12. The main body 1 has a water-stopping component 2 inside. The water-stopping component 2 seals the inlet 11 and can prevent the liquid from falling.
[0032] Based on the above technical means: Under normal conditions, the water-stopping component 2 seals the liquid inlet 11, which can prevent the liquid from falling and play a role in stopping the water flow. The water in the plastic bottle 3 will not flow out. When the adapter valve and the plastic bottle 3 are installed on the humidifier 4 of the ventilator, the plastic bottle 3 on the humidifier 4 will lift the water-stopping component 2, thereby opening the liquid inlet 11 and allowing the liquid in the plastic bottle 3 to flow into the humidifier 4 of the ventilator. The plastic bottle 3 and the humidifier 4 are connected by the adapter valve. There is no need to install the humidifier 4 of the ventilator upside down. The operation is more convenient and there is no overflow.
[0033] Furthermore, the water-stopping assembly 2 includes a water-stopping valve 21, a valve core 22, and a reset member 23. The water-stopping valve 21 is connected to the valve core 22, and the reset member 23 is sleeved on the valve core 22. The water-stopping valve 21 has a bowl-shaped structure and is sealed on the liquid inlet 11. Both the water-stopping valve 21 and the valve core 22 are made of rubber, and the reset member 23 is a spring.
[0034] Based on the above technical means: Under normal conditions, the stop valve 21 is sealed on the liquid inlet 11, which can block the liquid from falling and play a role in stopping the water. The plastic bottle 3 on the ventilator humidifier 4 can lift the valve core 22 and the stop valve 21, and at the same time the reset part 23 is compressed, thereby opening the liquid inlet 11, so that the liquid in the plastic bottle 3 flows into the ventilator humidifier 4. The plastic bottle 3 and the ventilator humidifier 4 are connected by the adapter valve, which eliminates the need to install the ventilator humidifier 4 upside down, making the operation more convenient and preventing water overflow.
[0035] Furthermore, a bracket 16 is provided inside the main body 1. The bracket 16 is located below the liquid inlet 11. The valve core 22 is inserted into the bracket 16. One end of the valve core 22 is provided with a limit circle 221. One end of the reset member 23 abuts against the bracket 16 and the other end abuts against the limit circle 221.
[0036] Furthermore, the valve core 22 has a plug 222 at the other end opposite to the limiting circle 221. The plug 222, the limiting circle 221 and the valve core 22 are integrally injection molded. The plug 222 has an umbrella-shaped structure. The valve core 22 has a neck ring 223 below the plug 222. The stop valve 21 has a through hole 211 in the middle. The through hole 211 and the neck ring 223 are used together to form a tight fit. The umbrella-shaped plug 222 makes it convenient for the valve core 22 to be inserted into the stop valve 21.
[0037] Furthermore, an upward extension ring 13 is provided on the outside of the liquid inlet 11. The inner top surface of the extension ring 13 is arc-shaped. The outer wall of the stop valve 21 is in contact with the inner top surface of the extension ring 13. The inner top surface of the extension ring 13 matches the shape of the stop valve 21, so that a certain seal is formed between the extension ring 13 and the stop valve 21 to prevent liquid leakage.
[0038] Furthermore, two equally spaced screws 14 are provided on the lower outer wall of the main body 1. The screws 14 are used in conjunction with the swivel groove 42 in the humidifier 4 of the ventilator. The adapter valve can be installed on the humidifier by means of the screws 14. The screw connection method of the screws 14 is convenient for installation and disassembly.
[0039] Furthermore, multiple equally spaced protruding ribs 15 are provided on the upper outer wall of the main body 1. The protruding ribs 15 make the outer wall of the main body 1 convex, increasing the friction and making it easier for the user to rotate the main body 1.
[0040] This utility model is an adapter valve for a ventilator water tank that is compatible with ordinary plastic bottles 3. Its working principle is described with reference to the accompanying drawings:
[0041] The inlet tube of the humidifier 4 is connected to the main unit of the ventilator, and the outlet tube of the humidifier 4 is connected to the mask.
[0042] The adapter valve and plastic bottle 3 are connected by a threaded connection. Then, the adapter valve and plastic bottle 3 are installed on the ventilator humidifier 4 by means of a screw 14. When the adapter valve is rotated, the plastic bottle 3 will contact the limit circle 221, thereby lifting the stop valve 21 and the valve core 22, opening the liquid inlet 11. The water in the plastic bottle 3 flows into the bottom of the adapter valve through the liquid inlet 11, and then flows into the ventilator humidifier 4 through the liquid outlet 12 of the adapter valve for humidification.
[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
