Description

Technical Field

[0001] This utility model relates to the field of ventilator technology, and mainly to a water inlet structure for a ventilator water tank. Background Technology

[0002] Humidifiers are an important component of ventilators. The heated and humidified airflow 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 mask pressure, improving treatment efficacy and adaptability. This is especially important for patients who need long-term ventilator use, as humidifiers can effectively improve the comfort of patients using ventilators.

[0003] However, common humidification devices on the consumer market consist of many components such as a humidification chamber, heating plate, and water tank. Their structure is relatively complex, their size is large, and they are not convenient to carry. During the use of the ventilator, the mixed gas will carry away the moisture in the humidification device (humidification chamber). Therefore, the moisture in the humidification device (humidification chamber) will gradually decrease. The humidification device (humidification chamber) needs to maintain the liquid level at the optimal position. If there is too little humidified water, there is a risk of inadequate humidification and burning of the humidification device (humidification chamber). If there is too much humidified water, there is a risk of humidified water backflow causing aspiration by the patient. Utility Model Content

[0033] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0034] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0036] Example 1:

[0037] Please refer to the following for details. Figure 1-8 A water inlet structure for a ventilator water tank includes an inlet pipe 11 and a transfer valve 2. The inlet pipe 11 is mounted on an upper cover 13, and the transfer valve 2 is detachably connected to the inlet pipe 11. The structure also includes a throttling mechanism, which is an airway pipe 12. The airway pipe 12 is mounted on the upper cover 13. One end of the airway pipe 12 is connected to the inlet pipe 11, and the other end is located in a humidification chamber 14. The bottom of the airway pipe is flush with the bottom of the inlet pipe 11. A heating plate 15 is provided at the bottom of the humidification chamber 14 to heat and humidify the water in the humidification chamber 14.

[0038] Based on the above technical means: the vent pipe 12 and the water inlet pipe 11 form an inverted U-shaped pipe. When the water overflows the bottom of the water inlet pipe 11 and the vent pipe 12, it will block the bottom of the water inlet pipe 11 and the air duct, so that the water can no longer enter the humidification chamber 14. When the water in the humidification chamber 14 is heated and evaporated, the water level drops, the water inlet pipe 11 and the vent pipe 12 open, the vent pipe 12 vents, and the water inlet pipe 11 is drained again, so that the water level in the humidification chamber 14 is always stable (maintained at the optimal horizontal position), ensuring the heating efficiency of the heating plate 15 and not affecting its use.

[0039] Furthermore, the adapter valve 2 includes an adapter 21, a stop valve 22, a valve core 23, and a reset component 24. The adapter 21 has a connecting ring 213 inside and several outlets 214 at its bottom. The valve core 23 is inserted into the connecting ring 213, with one end of the valve core 23 connected to the stop valve 22. The reset component 24 is sleeved on the valve core 23. The other end of the valve core 23 has a limiting circle 231. One end of the reset component 24 abuts against the connecting ring 213, and the other end abuts against the limiting circle 231. The adapter 21 has a hollow structure and includes an upper part 211 and a lower part 212. The upper part 211 and the lower part 212 are an integral structure and are interconnected. The upper part 211 has an internal thread.

[0040] Furthermore, a partition 111 is provided inside the water inlet pipe 11, which divides the internal space of the water inlet pipe 11 into two parts. A pin 112 and a water inlet hole 113 are provided on the partition 111. The pin 112 is located in the middle of the partition 111 and is directly opposite to the limiting circle 231. The water inlet hole 113 is located outside the pin 112.

[0041] Based on the above technical means: Under normal conditions, the stop valve 22 of the transfer valve 2 is sealed at the top of the lower part 212, which plays a role in stopping water flow and the water in the tank will not flow into the humidification chamber 14. When the transfer valve 2 is installed on the inlet pipe 11, the pin 112 can lift the valve core 23 and the stop valve 22, and the reset part 24 is compressed, thereby opening the flow channel 216, allowing the water in the tank to flow into the inlet pipe 11. The water tank and the humidifier are connected by the transfer valve 2, and the humidifier does not need to be installed upside down, making the operation more convenient and preventing water overflow.

[0042] Furthermore, the water inlet pipe 11, the vent pipe 12, and the top cover 13 are an integral structure, which is made by injection molding. The integral structure is more robust and stable.

[0043] Furthermore, four connecting legs 215 are provided on the outer side of the connecting ring 213. The connecting legs 215 are connected to the inner wall of the lower part 212, and the connecting legs 215 divide the inner hole of the lower part 212 to form four flow channels 216.

[0044] Furthermore, the top of the water inlet pipe 11 is provided with two locking grooves 114, and the outer wall of the lower part 212 is provided with a number of locking locks 217 equal to the number of locking grooves 114. The locking locks 217 are used in conjunction with the locking grooves 114, and the locking locks 217 can be screwed into the locking grooves 114.

[0045] Based on the above technical means: the transfer valve 2 (lower part 212) is installed on the water inlet pipe 11 by means of a screw thread. The screw thread connection method can ensure the stability of both and is also easy to disassemble.

[0046] Example 2:

[0047] Please refer to the following for details. Figure 9 The rest of this embodiment is the same as that of embodiment 1, except that: the throttling mechanism is the stop float 3, which is installed in the water inlet pipe 11. The inside of the stop float 3 is a hollow structure. Specifically, the diameter of the upper part 211 of the stop float 3 is less than the diameter of the water inlet pipe 11 and less than the diameter of the lower part 212 of the stop float 3. The upper part 211 of the stop float 3 is fitted into the water inlet pipe 11.

[0048] Based on the above technical means: when water enters the humidification chamber 14, the water level in the humidification chamber 14 will continue to rise, and the water stop float 3 will also rise with the water level. When the water level rises to a certain height, the water stop float 3 will block the water inlet pipe 11, and the water supply will stop. The heating plate 15 will continuously heat the water in the humidification chamber 14. During the heating process, the water will turn into water vapor, the water level will drop, the water stop float 3 will drop with the water level, and the water inlet pipe 11 will reopen. At this time, water can be supplied normally again, ensuring the heating efficiency of the heating plate 15.

[0049] In this application, the water tank uses a common threaded plastic bottle found in the consumer market. It is connected to the adapter 21 (upper part 211) via a threaded connection. The use of a plastic bottle to replace the traditional water tank simplifies the structure of the humidifier. The plastic bottle is disposable after use and will not form scale, thus ensuring the therapeutic effect of the ventilator.

[0050] This utility model relates to a water inlet structure for a ventilator's water tank. Its working principle is explained in conjunction with the accompanying drawings:

[0051] The inlet tube 16 of the humidifier is connected to the main unit of the ventilator, and the outlet tube 17 of the humidifier is connected to the mask.

[0052] The adapter valve 2 and the water tank are connected by a threaded connection, and then the adapter valve 2 and the water tank are installed on the water inlet pipe 11 by a screw thread. When the adapter valve 2 and the water tank are installed in place, the ejector pin 112 contacts the limit circle 231, lifting the stop valve 22 and the valve core 23, opening the lower 212 channel. Water in the water storage bottle flows into the upper part of the partition 111 through the flow channel 216 and the water outlet 214, and then enters the water inlet pipe 11 through the water inlet hole 113, and enters the humidification chamber 14. Under the action of the heating plate 15, the water is heated into water vapor. Finally, the gas carrying the water vapor enters the mask through the gas outlet pipe 17, continuously providing the user with humid and high-quality gas.

[0053] When the water level rises to a certain height, the inlet pipe 11 is blocked. After the water in the humidification chamber 14 is consumed, the water level drops, and the inlet pipe 11 is reopened to continue water flow, so that the water level in the humidification chamber 14 remains stable, ensuring the heating efficiency of the heating plate 15.

[0054] 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.
