[0040] However, because the sterilization chamber is filled with steam during the sterilization process, and the temperature inside the sterilization chamber remains high after sterilization, the sterilized instruments in the storage container can only be taken out after the temperature inside the sterilization chamber drops, and the next batch of instruments can be sterilized. This results in low sterilization efficiency of the steam sterilization device.
[0041] Therefore, how to improve the efficiency of steam sterilization equipment is a technical problem that urgently needs to be solved in this field.
[0042] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.
[0043] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0044] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0045] like Figures 1 to 6 As shown, some embodiments provide a pure steam sterilization device, including: an inner liner 2, a pressure cap 3, and a detachable handle 4. The interior of the inner liner 2 is suitable for being filled with steam to achieve the effect of disinfection and sterilization. The pressure cap 3 is located at the opening on the inner liner 2, and its main function is to seal the inner liner 2. A material carrier 5 is also provided inside the inner liner 2, which is used to support the instruments to be sterilized. The detachable handle 4 is located on the pressure cap 3 or on the material carrier 5. Specifically, when it is necessary to remove the sterilized instruments, the detachable handle 4 needs to be attached to the material carrier 5. In other states, the detachable handle 4 is attached to the pressure cap 3.
[0046] Please see Figure 3The material carrier 5 is provided with equally spaced mounting holes 51. The mounting holes 51 are mainly used to allow steam to pass through and can also be used to connect the detachable handle 4. In order to enhance the stability of picking up the parts, the diameter of the material carrier 5 is d1. The length of the detachable handle 4 is h. h > 3 / 4d1. The length of the detachable handle 4 is set between the clean material carrier 5, so that the material carrier 5 can be better balanced during the movement process.
[0047] Please see Figure 5 and combined Figure 6 The pressure cap 3 is provided with a screw connector 31, which includes two U-shaped blocks 32. The U-shaped blocks 32 are disposed on the pressure cap 3. The opening directions of the two U-shaped blocks 32 are opposite. The U-shaped blocks 32 are provided with round holes 33. In order to prevent the detachable handle 4 from easily coming off the screw connector 31, the opening width of the U-shaped block 32 is set to d2, and the diameter of the round hole 33 is d3, where d2 < d3. The short rod 43 is suitable for being inserted into the round hole 33 from the opening position of the U-shaped block 32.
[0048] Please see Figure 5 and combined Figure 6 Both the inner walls of the circular hole 33 and the mounting hole 51 are provided with annular grooves 34 that fit the anti-reverse ring 44; it should be further noted that... Figure 5 In the diagram, direction F is the direction in which the detachable handle 4 needs to be rotated to assemble the cover 3. Before assembling the cover 3 and the detachable handle 4, the quick-release piece 42 needs to be placed near the opening of the U-shaped block 32. Then, rotate the detachable handle 4 in direction F so that the quick-release piece 42 is engaged in the round hole 33. This will allow the cover 3 to be moved by lifting the detachable handle 4. The annular groove 34 is used to enhance the stability of the connection between the detachable handle 4 and the screw connector 31 or the mounting hole 51.
[0049] Please see Figure 3 The detachable handle 4 includes a grip 41 and a quick-release component 42. The grip 41 is arc-shaped, and its curvature matches the curvature of the human hand, making it easy to grip and exert force. The quick-release component 42 is located below the grip 41 and near both ends. The quick-release component 42 is suitable for being inserted into the mounting hole 51 to lift the material tray 5 or snap it into the screw connector 31 of the pressure cap 3.
[0050] Please see Figure 3 The quick-release component 42 includes a short rod 43 and at least one anti-reverse ring 44, which is fitted onto the short rod 43. The anti-reverse ring 44 corresponds one-to-one with the ring groove 34. The outer diameter of the anti-reverse ring 44 is larger than the inner diameter of the mounting hole 51. After the short rod 43 extends into the mounting hole 51, the inner wall of the mounting hole 51 presses against the anti-reverse ring 44.
[0051] Some embodiments also provide a pure steam sterilization device, including: an outer shell 1, an inner liner 2, a material carrier 5, and a detachable handle 4. The inner liner 2 is disposed inside the outer shell 1, and the upper part of the inner liner 2 extends outside the outer shell 1. The material carrier 5 is disposed inside the inner liner 2, and the carrier 5 is provided with mounting holes 51. The detachable handle 4 is connected to the material carrier 5 through the mounting holes 51. The material carrier 5 is provided with mounting holes 51 arranged at equal intervals. The mounting holes 51 are mainly used to allow steam to pass through and can also be used to connect the detachable handle 4. In order to enhance the stability of picking up the parts, the diameter of the material carrier 5 is d1. The length of the detachable handle 4 is h. h > 3 / 4d1, which can better balance the material carrier 5 during the movement process.
[0052] Please see Figure 3 The detachable handle 4 includes a grip 41 and a quick-release component 42. The grip 41 is arc-shaped, and its curvature matches the curvature of the human hand, making it easy to grip and exert force. The quick-release component 42 is located below the grip 41 and near both ends. The quick-release component 42 is suitable for being inserted into the mounting hole 51 of the material carrier 5 and for removing the material carrier 5 from the inner liner 2 under the lifting force.
[0053] Please see Figure 3 The quick-release component 42 includes a short rod 43 and at least one anti-reverse ring 44. The anti-reverse ring 44 is fitted onto the short rod 43 and corresponds one-to-one with the ring groove 34. The outer diameter of the anti-reverse ring 44 is larger than that of the mounting hole 51. After the short rod 43 extends into the mounting hole 51, the inner wall of the mounting hole 51 presses against the anti-reverse ring 44.
[0054] In summary, before use, with the detachable handle 4 installed on the pressure cap 3, place the instruments to be sterilized on the material carrier tray 5, seal it through the opening at the top of the inner liner 2 of the pressure cap 3, and finally, steam is generated inside the device for sterilization. After sterilization, remove the pressure cap 3 from the inner liner 2, and then... Figure 5 Rotate the detachable handle 4 in the opposite direction of F to separate the detachable handle 4 from the pressure cover 3. Finally, lift the detachable handle 4, align the short rod 43 with the mounting hole 51, and press the grip 41 to make the anti-reverse ring 44 fully enter the mounting hole 51, so that the material carrier 5 can be removed from the inner liner 2.
[0055] This invention, by setting up a quick-release component 42 and a material carrier tray 5, allows the detachable handle 4 to be immediately attached to the material carrier tray 5 after being removed from the pressure cover 3, achieving the effect of simultaneously removing the material carrier tray 5 and the sterilization components from the device. This solves the problem of needing to cool down before removing the components, enhances the convenience of using the sterilizer, and improves the efficiency of the device. By setting up an annular groove 34, the stability of the connection between the detachable handle 4 and the screw connector 31 or the mounting hole 51 is enhanced. By setting up a longer detachable handle 4, the tilting or tipping of the material carrier tray 5 during the overall movement is avoided, improving the stability of component removal.
