[0002] Oxygen humidifier bottles are key consumables used in emergency situations and ward care in medical facilities, integrated with central oxygen supply systems. They alleviate respiratory irritation and improve the effectiveness of oxygen therapy by humidifying pure oxygen. The product consists of components such as connectors, the bottle body, and oxygen filters, and comes in two types: plug-in and embedded. Plug-in bottles are becoming increasingly popular due to their ease of cleaning and maintenance.

[0003] Existing oxygen humidification bottle production equipment typically involves blowing the oxygen humidification bottle into shape, and then manually filling the shaped oxygen humidification bottle. This method cannot form and fill the oxygen humidification bottle in one go, which increases the number of production steps and fails to effectively improve the production efficiency of oxygen humidification bottles.

[0004] Therefore, a solution is needed. Utility Model Content

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3 This utility model provides a technical solution: Example 1

[0016] Regarding the aforementioned problems: existing oxygen humidification bottle production equipment generally involves blowing the oxygen humidification bottle into shape, and then manually filling the shaped oxygen humidification bottle. This method cannot form and fill the oxygen humidification bottle in one go, which increases the number of production steps and cannot effectively improve the production efficiency of oxygen humidification bottles.

[0017] The solution is as follows: A blow molding device includes a device body 1, which includes a gas distribution block 2, a first gas pipe device 3, a second gas pipe device 4, a second blow needle 5, a first blow needle 6, a filling needle 7, and an oxidizing moisture cylinder forming mold 8. The first gas pipe device 3 is installed at the top right end of the gas distribution block 2, the second gas pipe device 4 is installed at the top right end of the gas distribution block 2, the second blow needle 5 and the first blow needle 6 are both installed at the bottom of the gas distribution block 2, the filling needle 7 is sleeved inside the first blow needle 6 and passes through the gas distribution block 2, and a filling valve 13 is installed at the top of the filling needle 7. The bottle forming mold 8 is located below the second blow needle 5, the first blow needle 6 and the filling needle 7. The gas distribution block 2 is provided with a first air channel 14 and a second air channel 15. The top left end of the gas distribution block 2 is provided with a first air inlet 16, the top right end of the gas distribution block 2 is provided with a second air inlet 17, the bottom of the gas distribution block 2 is provided with a first exhaust port 18 and a second exhaust port 19, and the top of the gas distribution block 2 is provided with a through port 20. The first air inlet 16, the first exhaust port 18 and the first air channel 14 are a through structure, and the second air inlet 17, the second exhaust port 19 and the second air channel 15 are a through structure.

[0018] Analysis of the above content: The main body 1 of the device uses the gas distribution block 2 as the core supporting component. It is connected to the gas source through the first gas pipe device 3 and the second gas pipe device 4. The gas is transmitted to the first blow needle 6 and the second blow needle 5 through the first gas channel 14 and the second gas channel 15 inside the gas distribution block 2, respectively, to blow and form the bottle preform in the lower oxidation moisture bottle forming mold 8. At the same time, the filling needle 7 is nested inside the first blow needle 6, penetrates the gas distribution block 2 and is controlled by the top filling valve 13. After the bottle preform is formed, the filling operation can be performed directly to realize the integrated process of forming and filling. When forming is only required: the filling valve 13 is closed and the blowing is controlled by the first and second gas pipe devices 3 and 4 to complete the bottle preform forming. When forming and filling are required simultaneously: the filling valve 13 is opened, and while the first blow needle 6 blows and forms the preform, the filling needle 7 injects the material into the formed bottle. Single / multiple production switching: according to the production demand, one or more blow needles-mold combinations can be selected to work (in conjunction with the design of multiple exhaust ports below). Example 2

[0019] Please see Figure 1-3 The present invention provides a technical solution based on Embodiment 1: the first exhaust port 18 is provided in two groups and is distributed in a horizontally equidistant manner, the second exhaust port 19 is provided in two groups and is distributed in a horizontally equidistant manner, and the through port 20 is provided in two groups and is distributed in a horizontally equidistant manner.

[0020] Analysis of the above content: By setting two sets of first exhaust ports 18, second exhaust ports 19, and through ports 20, multiple components can be installed, thereby producing multiple oxidizing and moist gas cylinders at one time, improving the production efficiency of oxidizing and moist gas cylinder forming. The first exhaust ports 18 (2 sets) and second exhaust ports 19 (2 sets) at the bottom of the gas distribution block 2 are respectively connected to the first air passage 14 and the second air passage 15, used to accurately distribute the gas to the corresponding blow needle; the through ports 20 (2 sets) at the top are used for the through installation of filling needles 7. The horizontal equidistant distribution ensures that each component is subjected to uniform force and accurate alignment. Small batch production: only one set of exhaust ports and through ports is used to reduce energy consumption. Large batch production: both sets of exhaust ports and through ports work simultaneously to achieve dual-station synchronous production. Example 3

[0021] Please see Figure 1-3 The present invention provides a technical solution based on embodiment one: the first air tube device 3 includes a first tube body 9 and a first valve 10. The first valve 10 is installed on the first tube body 9. The bottom of the first tube body 9 is provided with a threaded sealing connector 21. The first tube body 9 is connected to the first air inlet 16 through the threaded sealing connector 21. The first tube body 9 and the first air passage 14 are a through structure.

[0022] Analysis of the above: The first tube 9 connects to the first air inlet 16 of the gas distribution block 2 via a threaded sealing connector 21. External air is delivered to the first air passage 14 via the first tube 9. The first valve 10 controls the airflow, pressure, and flow rate. Finally, the air is transmitted to the first blow needle 6 via the first exhaust port 18. For softer preform materials (e.g., PE): the opening of the first valve 10 is reduced to lower the blowing pressure and prevent excessive stretching and breakage of the bottle. For harder preform materials (e.g., PET): the valve opening is increased to raise the blowing pressure and ensure full bottle forming. Temporary shutdown: the first valve 10 is closed to cut off the air supply and avoid gas waste. The threaded sealing connector 21 ensures the sealing performance between the air pipe and the gas distribution block, preventing pressure loss due to gas leakage. The first valve 10 can precisely adjust airflow parameters to adapt to the forming needs of preforms of different materials and specifications. The through-type structure (first tube 9 and first air passage 14) reduces airflow resistance and ensures stable blowing pressure. Example 4

[0023] Please see Figure 1-3 The present invention provides a technical solution based on embodiment one: the second air pipe device 4 includes a second pipe body 11 and a second valve 12. The second valve 12 is installed on the second pipe body 11. A threaded sealing connector 21 is also installed at the bottom of the second pipe body 11. The second pipe body 11 is connected to the second air inlet 17 through the threaded sealing connector 21. The second pipe body 11 and the second air passage 15 are in a through structure.

[0024] Analysis of the above content: Similar to the first air pipe device 3, the second pipe body 11 is connected to the second air inlet 17 of the air distribution block 2 through the threaded sealing connector 21. The air source is transmitted to the second blow needle 5 through the second pipe body 11, the second air passage 15, and the second exhaust port 19. The second valve 12 controls the airflow parameters and independently completes the blowing and forming of the corresponding station. Dual-station differentiated production: By controlling the difference in opening degree between the second valve 12 and the first valve 10, the blowing pressure of the two stations is controlled, and bottles with different wall thicknesses are produced at the same time. Single-station standby: When the first air pipe device 3 fails, the second air pipe device 4 is activated separately to ensure that production is not interrupted. Example 5

[0025] Please see Figure 1-3 Based on Embodiment 1, this utility model provides a technical solution: the top of the oxidation moisture bottle forming mold 8 is respectively provided with a first blowing port 22 and a second blowing port 23.

[0026] Analysis of the above content: The first blow port 22 and the second blow port 23 at the top of the mold are precisely aligned with the first blow needle 6 and the second blow needle 5, respectively. The preform is placed in the mold, and the blow needle blows air into the preform through the blow port, so that the preform fits the inner wall of the mold and is formed, ultimately forming an oxygen humidification bottle shape that is consistent with the mold cavity.

[0027] Working Principle: After the extruded preform reaches the appropriate length, the main mold closes, clamping the bottom of the preform. The preform is divided into two connected cavities within the mold. Gas is supplied through the first air pipe device 3 and the second air pipe device 4. The gas is transmitted through the first air passage 14 and the second air passage 15 inside the gas distribution block 2 to the first blow needle 6 and the second blow needle 5, respectively, to blow and shape the preform within the lower oxidation moisture bottle forming mold 8. Simultaneously, the filling needle 7 is nested inside the first blow needle 6, penetrating the gas distribution block 2 and controlled by the top filling valve 13. Filling can be performed directly after the preform is formed, achieving an integrated forming and filling process. For forming only: close the filling valve 13 and control the blowing through the first and second air pipe devices 3 and 4 to complete the preform forming. For simultaneous forming and filling: open the filling valve 13, and while the first blow needle 6 blows and shapes the preform, the filling needle 7 injects liquid into the formed bottle. After filling, the blow needle and filling needle return to their initial positions. The mold is sealed, the bottle is formed, the mold is opened, and then the cycle is repeated.

[0028] The present invention comprises: 1. Device body; 2. Gas distribution block; 3. First gas pipe device; 4. Second gas pipe device; 5. Second blow needle; 6. First blow needle; 7. Filling needle; 8. Oxidation moisture cylinder forming mold; 9. First tube body; 10. First valve; 11. Second tube body; 12. Second valve; 13. Filling valve; 14. First air passage; 15. Second air passage; 16. First air inlet; 17. Second air inlet; 18. First exhaust port; 19. Second exhaust port; 20. Through-hole; 21. Threaded sealing connector; 22. First blow nozzle; 23. Second blow nozzle. All components are general standard parts or parts known to those skilled in the art, and their structure and... The principles are all known to those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this invention is that existing oxygen humidification bottle production equipment generally involves blowing the oxygen humidification bottle into shape, and then manually filling the formed oxygen humidification bottle. This method cannot form and fill the oxygen humidification bottle in one go, resulting in increased production steps and failing to effectively improve the production efficiency of oxygen humidification bottles. This invention, through the combination of the above-mentioned components, can accurately blow and form the bottle preform. After forming, filling can be carried out immediately with the help of the internally connected filling needle, which greatly enhances the continuity of production and significantly improves the degree of automation.
