[0040] Please refer to the following: Figures 1 to 3 The first embodiment of this application provides a humidification tank 10 with a glue-free and chemical solvent-free dropper connector for use in breathing equipment. The humidification tank 10 consists of a humidification tank body 12, a water inlet 13, an infusion tube connector 14, and a connector locking buckle 15. The humidification tank body 12 has an upper cover end 121 and a base end 122. The water inlet 13 is fixed to the upper cover end 121 and has a water inlet hole 132 and several locking parts 131 for connecting the infusion tube 11 to the humidification tank 10. The infusion tube connector 14 includes an insertion section 141, a limiting boss 142, and an insertion hole section 143. The infusion tube 11 is inserted into the infusion tube connector 14 through the insertion section 141, and the limiting boss 142 prevents the infusion tube 11 from being inserted too deeply. Next, the inlet section 143 of the infusion tube connector 14 is inserted into the water inlet 132 of the humidification tank 10. The limiting boss 142 abuts against the edge of the water inlet 132, providing additional stability. To ensure a secure connection, the locking part 131 on the side wall of the water inlet 13 engages with the connector buckle 15. The connector buckle 15 is fitted onto the water inlet 13, and by rotation or other fixing methods, the fixing part 152 on the buckle engages with the locking part 131, firmly fixing the infusion tube connector 14 to the water inlet 132. Simultaneously, the through hole 151 on the connector buckle 15 allows the infusion tube 11 to pass through, ensuring its positioning and fixation. This mechanical connection method provides a novel humidification tank, thereby avoiding the use of glue curing processes, eliminating the problem of volatile organic compounds, improving equipment safety, and eliminating the need for air drying and curing time, shortening the manufacturing time and cost of the humidification tank 10, and increasing the production capacity of the humidification tank 10.

[0041] Please refer to the following: Figures 1 to 4The humidification tank 10 with a glue-free and solvent-free dropper connector includes an infusion tube 11, a humidification tank body 12, a water inlet 13, an infusion tube connector 14, and a connector lock 15. The infusion tube 11 is used to deliver liquid into the humidification tank body 12. Specifically, the liquid can be distilled water, sterile water, a mixture of distilled water and medicine, or a medicine solution, etc. The humidification tank body 12 is used to humidify gas. The humidification tank body 12 has an upper cover end 121 and a base end 122 arranged opposite to each other. The base end 122 is used to install a heat-conducting base. The water inlet... Inlet 13 is used to inject the liquid introduced by the infusion tube 11 into the humidification tank body 12. The inlet 13 is fixedly installed on the upper cover end 121. The inlet 13 has an inlet hole 132 and several locking parts 131 are fixedly installed on the inlet 13. The infusion tube connector 14 is used to connect the infusion tube 11 to the inlet 13. The infusion tube connector 14 has an insertion section 141, a limiting boss 142, and an insertion hole section 143. The insertion section 141, the limiting boss 142, and the insertion hole section 143 are arranged from top to bottom in a specific order. The following configuration is provided: the inlet section 143 is detachably connected to the water inlet 132, and the insertion section 141 is detachably connected to the infusion tube 11, thereby making the infusion tube 11 and the connector lock 15 easy to disassemble and maintain, improving the service life and convenience of the humidification tank 10; the connector lock 15 is provided with a through hole 151 for the infusion tube 11 to pass through, and several fixing parts 152 are fixedly provided on the connector lock 15, which are used to engage with the locking part 131 and the infusion tube connector 11. 4. The infusion tube 11 is fixed to the water inlet 132, and then a stable connection between the humidification tank 10 and the infusion tube 11 is achieved through the cooperation of the infusion tube connector 14, connector buckle 15 and locking part 131. This avoids the loosening problem that may be caused by traditional glue connection, eliminates the process of using glue for curing, eliminates the safety risks caused by the volatilization of volatile organic substances, ensures the safety of users, and eliminates the need for air drying and curing time, shortens the manufacturing time and cost of the humidification tank 10, and increases the production capacity of the humidification tank 10 product.

[0042] Please refer to the following: Figure 3In some embodiments, the infusion tube connector 14 further includes an ultrasonic wire 1421 and a buckle 1422. The ultrasonic wire 1421 is disposed at the end of the limiting boss 142 opposite to the insertion section 141. The ultrasonic wire 1421 is arranged in a ring and is used for ultrasonic welding with the inlet 13. The buckle 1422 is used to prevent the infusion tube 11 from detaching from the infusion tube connector 14. The buckle 1422 is fixedly disposed on the insertion section 141, eliminating the use of glue for curing, eliminating the safety risks caused by the volatilization of volatile organic substances, ensuring the safety of users, and eliminating the need for air drying and curing time, shortening the manufacturing time and cost of the humidification tank 10, and increasing the production capacity of the humidification tank 10 product.

[0043] Please refer to the following: Figures 4 to 5 In some embodiments, the buckle 1422 is tapered, and the maximum diameter of the buckle 1422 is slightly larger than the diameter of the infusion tube 11, thereby effectively preventing the infusion tube 11 from being pulled out of the buckle 1422 after being subjected to force, and improving the assembly efficiency of the infusion tube 11 and the infusion tube connector 14.

[0044] Please refer to the following: Figure 2 and Figure 3 In some embodiments, the cross-section of the ultrasonic wire 1421 along the axial direction of the infusion tube connector 14 is set to a V-shape, triangle, or cone shape, which helps to concentrate and transfer energy during ultrasonic welding, improves welding efficiency and quality, and makes the connection between the infusion tube connector 14 and the inlet 13 more stable. This eliminates the need for the use of glue for curing, removes the safety risks caused by the volatilization of volatile organic substances, ensures the safety of users, and eliminates the need for air drying and curing time, shortening the manufacturing time and cost of the humidification tank 10 and increasing the production capacity of the humidification tank 10.

[0045] Please refer to the following: Figure 2 and Figure 3 In some embodiments, the sharper the tip of the ultrasonic wire 1421, the better, so that the vibration energy can be concentrated at the tip of the triangle, and then the accumulated heat can form a uniform plastic melt flow throughout the welding interface, which improves welding efficiency and quality, and makes the connection between the infusion tube connector 14 and the water inlet 13 more stable. This eliminates the need for the process of using glue for curing, eliminates the safety risks caused by the volatilization of volatile organic substances, ensures the safety of users, and eliminates the need for air drying and curing time, shortening the manufacturing time and cost of the humidification tank 10 and increasing the production capacity of the humidification tank 10 product.

[0046] Please refer to the following: Figure 2 and Figure 3In some embodiments, the principle of ultrasonic wire 1421 welding is to use the high-frequency vibration of the welding head of ultrasonic wire 1421 to cause high-frequency friction between the infusion tube connector 14 and the water inlet 13, converting mechanical energy into heat energy. The heat energy dissolves the molecules on the welding surfaces of the infusion tube connector 14 and the water inlet 13, restoring their activity. Then, with the assistance of external force, the molecules entangle with each other to achieve the welding purpose, thereby greatly improving the airtightness and welding quality between the infusion tube connector 14 and the water inlet 13, avoiding the loosening problem that may be caused by traditional glue connection, abandoning the process of using glue for curing, eliminating the safety risks caused by the volatilization of volatile organic substances, ensuring the safety of users, improving the safety of equipment, and eliminating the need for air drying and curing time, shortening the manufacturing time and cost of the humidification tank 10, and increasing the production capacity of the humidification tank 10 product.

[0047] Please refer to the following: Figure 2 and Figure 3 In some embodiments, the diameter of the ultrasonic wire 1421 is set to 1.2 to 2 times the diameter of the water inlet 132, that is, the ultrasonic wire 1421 is located outside the water inlet 132, thereby optimizing the welding effect between the infusion tube connector 14 and the water inlet 13, ensuring the strength and airtightness of the connection between the infusion tube connector 14 and the water inlet 13, and improving the reliability of the overall structure. The diameter of the ultrasonic wire 1421 is larger than the diameter of the water inlet 132, which can uniformly transmit the stress during welding, reduce stress concentration, and improve the fatigue resistance of the connection between the infusion tube connector 14 and the water inlet 13.

[0048] Please refer to the following: Figures 1 to 5 In some embodiments, each of the locking parts 131 includes a locking boss 1311, which is fixedly disposed on the side wall of the inlet 13, thereby enabling the infusion tube connector 14 to be quickly installed and fixed, simplifying the assembly process and improving production efficiency.

[0049] Please refer to the following: Figures 1 to 5In some embodiments, each of the fixing members 152 includes a plurality of screw fasteners 1521, which are fixedly disposed on the inner sidewall of the connector latch 15. The screw fasteners 1521 are used to cooperate with the locking boss 1311 and the infusion tube connector 14 to fix the infusion tube 11 onto the inlet hole 132. The infusion tube 11 extends through the outlet hole 151, is sleeved in the insertion section 141, and the inlet section 143 is inserted into the inlet hole 132. The limiting boss 142 abuts against the edge of the inlet hole 132. The inlet 13 and the infusion tube connector 14 are ultrasonically tested using the ultrasonic wire 1421. Welding is performed by fitting the connector locking buckle 15 onto the water inlet 13, rotating the connector locking buckle 15, and screwing the plurality of the screw fasteners 1521 into the locking boss 1311. Thus, through the cooperation of the infusion tube connector 14, the locking boss 1311, and the screw fasteners 1521, a stable connection between the humidification tank 10 and the infusion tube 11 is achieved, avoiding the loosening problems that may be caused by traditional glue connections, eliminating the process of using glue for curing, eliminating the safety risks caused by the volatilization of volatile organic substances, ensuring the safety of users, improving the safety of equipment, and eliminating the need for air drying and curing time, shortening the manufacturing time and cost of the humidification tank 10, and increasing the production capacity of the humidification tank 10 product.

[0050] In some embodiments, the locking boss 1311 includes a horizontal boss, a vertical boss, and a locking boss. The horizontal and vertical bosses are vertically arranged to form a locking space. The horizontal and vertical bosses are integrally formed. The limiting boss 142 is provided on the upper cover end 121. The limiting boss 142 is used to prevent several screw fasteners 1521 from sliding out of the locking space, thereby effectively preventing the infusion tube 11 from falling off during use and increasing the safety and reliability of the connection between the infusion tube connector 14 and the inlet 13.

[0051] Please refer to the following: Figure 6 In some embodiments, each of the locking parts 131 includes a snap-fit ​​boss 1312, which is disposed on the side wall of the inlet 13, thereby enabling the infusion tube connector 14 to be quickly installed and fixed, simplifying the assembly process and improving production efficiency.

[0052] Please refer to the following: Figure 6 In some embodiments, the end face of the snap-fit ​​boss 1312 is flush with the end face of the inlet 13, thereby reducing the difficulty of snapping the connector lock 15 with the inlet 13, thus enabling the infusion tube connector 14 to be quickly installed and fixed, simplifying the assembly process and improving production efficiency.

[0053] Please refer to the following: Figure 6 In some embodiments, several fasteners 152 each include a snap-fit ​​groove 1522, which is formed on the side wall of the connector latch 15. The snap-fit ​​boss 1312 is adapted to the size of the snap-fit ​​groove 1522. The snap-fit ​​groove 1522 is used to cooperate with the snap-fit ​​boss 1312 and the infusion tube connector 14 to fix the infusion tube 11 on the water inlet 132. The infusion tube 11 extends out of the through hole 151 and is sleeved in the insertion section 141. The inlet section 143 is inserted into the water inlet 132. The limiting boss 142 abuts against the edge of the water inlet 132. The ultrasonic wire 1421 is used for this purpose. The inlet 13 and the infusion tube connector 14 are ultrasonically welded, and the connector locking buckle 15 is fitted onto the inlet 13. Several of the snap-fit ​​grooves 1522 are snapped into the snap-fit ​​bosses 1312, which greatly improves the airtightness and welding quality between the infusion tube connector 14 and the inlet 13, avoids the loosening problem that may be caused by traditional glue connection, eliminates the process of using glue for curing, eliminates the safety risks caused by the volatilization of volatile organic substances, ensures the safety of users, improves the safety of the humidification tank 10, and eliminates the need for air drying and curing time, shortens the manufacturing time and cost of the humidification tank 10, and increases the production capacity of the humidification tank 10 product.

[0054] Please refer to the following: Figure 7 and Figure 8In some embodiments, each of the locking parts 131 includes a thread 1313, which is disposed on the side wall of the inlet 13; each of the fixing parts 152 includes a threaded groove 1523, which is formed on the inner side wall of the connector lock 15. The threaded groove 1523 is adapted to the size of the thread 1313. The threaded groove 1523 is used to cooperate with the thread 1313 and the infusion tube connector 14 to fix the infusion tube 11 on the inlet hole 132, thereby improving the sealing performance of the inlet 13 and the connector lock 15, preventing liquid leakage, and improving the safety and reliability of the humidification tank 10; wherein, the infusion tube 11 passes through the through hole 151 and is sleeved in the insertion section 141. The inlet section 143 is inserted into the inlet hole 132, and the limiting boss 142 abuts against the edge of the inlet hole 132. The inlet 13 and the infusion tube connector 14 are ultrasonically welded using the ultrasonic wire 1421. The connector locking buckle 15 is fitted onto the inlet 13, and several threaded grooves 1523 are screwed into the threads 1313. This greatly improves the airtightness and welding quality between the infusion tube connector 14 and the inlet 13, avoids the loosening problem that may be caused by traditional glue connection, eliminates the process of using glue for curing, eliminates the safety risks caused by the volatilization of volatile organic substances, ensures the safety of users, and eliminates the need for air drying and curing time, shortens the manufacturing time and cost of the humidification tank 10, and increases the production capacity of the humidification tank 10.

[0055] In some embodiments, the "no glue, no chemical solvent" in the humidification tank 10 with glue-free and chemical solvent-free dropper connector described in this application means that no glue or other chemical solvents are used in the assembly process of the humidification tank body 12 and the infusion tube 11. This avoids the loosening problem that may be caused by traditional glue connections, eliminates the process of using glue for curing, eliminates the safety risks caused by the volatilization of volatile organic substances, ensures the safety of users, and eliminates the need for air drying and curing time, shortening the manufacturing time and cost of the breathing device and increasing the production capacity of the breathing device.
