Description

Technical Field

[0001] The utility model relates to the technical field of sterilization devices, and more specifically, to a low-temperature steam formaldehyde sterilization device. Background Art

[0002] In existing technologies, high-concentration formaldehyde vapor needs to be completely removed from the inside of the instrument through a decomposition process after completing the sterilization task. If the decomposition is not thorough, the residual formaldehyde may pose a risk of cross-infection to the patient. Formaldehyde is a harmful gas. Long-term exposure to low doses of formaldehyde may cause symptoms such as headaches, eye and respiratory irritation, and skin allergies, while high-dose formaldehyde exposure may cause serious health problems such as cancer. Therefore, it is crucial to ensure that formaldehyde is completely decomposed during the sterilization process. At the same time, there may be formaldehyde residues inside the sterilizer, which will pose a threat to the health of medical staff.

[0003] Secondly, during long-term use, aging, wear or damage of water pipes is inevitable, so they need to be replaced regularly. However, existing low-temperature steam formaldehyde sterilizers often lack an effective quick-connect mechanism, making the water pipe replacement process complicated and time-consuming, which not only increases maintenance costs, but may also affect the normal operation of the equipment.

[0004] In addition, the existing device cannot effectively adjust the water flow rate during use. During the sterilization process, the water flow rate is crucial to ensuring the disinfection effect. If the flow rate is too low, it may lead to incomplete sterilization. If the flow rate is too high, it may cause damage to the equipment. Therefore, the function of being able to adjust the water flow rate as needed is very important for improving sterilization efficiency and protecting equipment. Utility Model Content

[0036] A sliding rod 18 and a threaded rod 19 are connected between the fixed tube 9 and the moving block 11 . The threaded rod 19 is threadedly connected to the fixed tube 9 and the moving block 11 . The sliding rod 18 is slidably connected to the fixed tube 9 and the moving block 11 .

[0037] In this embodiment, during the use of the device, the filling valve 13 is manually closed, the steam generator 7 is connected to the water tank 8 so that the inside is filled with distilled water, the photocatalyst solution and the formaldehyde solution are manually poured into the first liquid reservoir 2 and the second liquid reservoir 6 respectively, the instrument to be sterilized is manually placed inside the box 1, and then the chamber door 12 is closed, and the filling valve 13 on the second liquid reservoir 6 is opened, so that the formaldehyde solution enters the steam generator 7 along the pipeline, so that the steam generator 7 vaporizes the formaldehyde solution and passes it into the box 1, so that it performs a sterilization process on the instrument.

[0038] See also Figure 6-7 As an implementation method of a low-temperature steam formaldehyde sterilization device for a speed regulating component: a speed regulating component is connected to one end of a sliding tube 10, and the speed regulating component includes a drain pipe 20, a water outlet pipe 21 and a rotating block 22. The drain pipe 20 is fixedly connected to the sliding tube 10, the water outlet pipe 21 is installed on one side of the drain pipe 20, and the rotating block 22 is rotatably connected between the drain pipe 20 and the water outlet pipe 21.

[0039] A thread groove 23 is formed inside the drain pipe 20 , and a thread connection block 24 is threadedly connected to the thread groove 23 . A rotating rod 25 is connected to one end of the thread connection block 24 .

[0040] A rotating spring 26 is disposed on the outer side of the rotating rod 25 , and a fixing block 27 is disposed on the inner side of the drain pipe 20 . One end of the rotating spring 26 abuts against the fixing block 27 , and the fixing block 27 and the rotating rod 25 are fixedly connected.

[0041] More specifically, when the flow rate needs to be adjusted, the rotating block 22 between the drain pipe 20 and the outlet pipe 21 is manually rotated, so that it drives the fixed block 27 and the rotating rod 25 to rotate. During the rotation process, the threaded connection block 24 at the bottom is driven to rotate, so that it rotates and moves along the thread groove 23 on the inner side of the drain pipe 20, so that the rotating spring 26 is compressed, thereby moving the threaded connection block 24 to a different position. In this way, when water flows in from one end of the drain pipe 20, the water flow rate is controlled due to the different positions of the threaded connection block 24.

[0042] In summary, when the overall device is in use or running: during the use of this device, the filling valve 13 is manually closed, the steam generator 7 is connected to the water tank 8 so that the inside is filled with distilled water, the photocatalyst solution and the formaldehyde solution are manually poured into the first liquid reservoir 2 and the second liquid reservoir 6 respectively, the instrument to be sterilized is manually placed inside the box 1, and then the chamber door 12 is closed, and the filling valve 13 on the second liquid reservoir 6 is opened, so that the formaldehyde solution enters the steam generator 7 along the pipeline, so that the steam generator 7 vaporizes the formaldehyde solution and passes it into the box 1, so that it is sterilized for the instrument. After a period of time, the ultraviolet lamp 5 is turned on, and then the filling valve 13 on the first liquid reservoir 2 is opened, so that the photocatalyst solution enters the spray head 4 along the pipeline to carry out the sterilization process. After a period of use, when the drain pipe 20 connected to the sliding pipe 10 needs to be replaced, the threaded rod 19 is manually rotated so that the moving block 11 is driven to slide along the inside of the fixed pipe 9 and the outside of the sliding pipe 10 under the promotion of the sliding rod 18. When the moving block 11 abuts against the clamping block 14, it is ejected from the clamping groove 15, as shown in FIG. Figure 5 As shown in , the clamping spring 16 on the top plate 17 is squeezed to release the restriction process on the sliding tube 10. At this time, the sliding tube 10 is taken out manually. After the new sliding tube 10 is inserted into the inner side of the fixed tube 9, the threaded rod 19 is rotated in the reverse direction so that the sliding rod 18 promotes the moving block 11 to move in the reverse direction, so that the abutment against the clamping block 14 is released, and the clamping block 14 is pushed to move under the action of the clamping spring 16, so that it is inserted into the clamping groove 15 of the sliding tube 10, so that the fixing process of the sliding tube 10 is completed.

[0043] When the flow rate needs to be adjusted, the rotating block 22 between the drain pipe 20 and the outlet pipe 21 is manually rotated to drive the fixed block 27 and the rotating rod 25 to rotate. During the rotation process, the threaded connection block 24 at the bottom is driven to rotate, so that it rotates and moves along the thread groove 23 on the inner side of the drain pipe 20, compressing the rotating spring 26, thereby moving the threaded connection block 24 to different positions. In this way, when water flows in from one end of the drain pipe 20, the water flow rate is controlled due to the different positions of the threaded connection block 24.

In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
