[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 as well as Figure 7 ,in, Figure 1 A schematic diagram of the overall structure of an injection pen cap assembly and an injection pen having the same assembly, provided by this utility model; Figure 2 A schematic cross-sectional view of a pen cap assembly for an injection pen and an injection pen having the same assembly, provided by this utility model.

[0026] In the specific implementation process, such as Figures 1-4 , Figure 6 as well as Figure 7 As shown, the present invention provides a pen cap assembly for an injection pen, including a pen cap body 1, a needle protection component, an ultraviolet disinfection component, and a power supply component. The needle protection component and the ultraviolet disinfection component are both located inside the pen cap body 1, and the power supply component is fixedly installed at one end of the pen cap body 1. A connecting groove 2 for connecting the power supply component is opened on the inner surface of the pen cap body 1. The top of the needle protection component is connected to the inside of the ultraviolet disinfection component through a connecting spring 3. A limiting ring 4 is fixedly provided inside the pen cap body 1.

[0027] In one specific embodiment, the limiting ring 4 is used to limit the installation of the power connection piece 10 and the light connection piece 11. At the same time, the limiting ring 4 isolates the power connection piece 10 and the light connection piece 11 from each other, preventing them from communicating with each other, so that the communication control element 9 loses its control function.

[0028] It should be noted that the connecting spring 3 serves to buffer and conform the movement of the needle protection component, and also controls the connection and disconnection of the UV disinfection component to the control component.

[0029] In one specific embodiment, a pen clip 19 is fixedly provided on the outer side of the pen cap body 1;

[0030] The ultraviolet disinfection component includes a disinfection lamp 5, a positive electrode connecting piece 6, and a negative electrode connecting piece 7. One end of the positive electrode connecting piece 6 and one end of the negative electrode connecting piece 7 are fixedly connected to the positive and negative electrodes of the disinfection lamp 5, respectively. A limiting collar 8 is provided inside the disinfection lamp 5. One end of the connecting spring 3 is fixedly sleeved on the surface of the limiting collar 8, and the other end of the connecting spring 3 is fixedly sleeved on the top surface of the needle protection component. The other end of the negative electrode connecting piece 7 is connected to the negative output end of the power supply component. A communication control component 9 is fixedly provided between the positive electrode connecting pieces 6. The communication control component 9 is fixedly installed on the top surface of the limiting ring 4, and the other end of the positive electrode connecting piece 6 is fixedly connected to the top surface of the communication control component 9.

[0031] It should be noted that the disinfection lamp 5 contains multiple miniaturized UV-C LEDs as a physical disinfection method, which destroys the DNA structure of microorganisms by emitting ultraviolet light, thereby achieving sterilization and disinfection.

[0032] The communication control component 9 includes a power connection piece 10 and a light connection piece 11. The power connection piece 10 and the light connection piece 11 are both fixedly installed on the top surface of the limiting ring 4. The top surface of the light connection piece 11 is fixedly connected to the bottom end of the positive electrode connection piece 6. One end of the power connection piece 10 is fixedly connected to the bottom end of the power supply component.

[0033] The needle protection component includes a protective component 12 and a flow guide 13. The flow guide 13 is sleeved on the surface of the protective component 12, and both ends of the flow guide 13 are respectively attached to the surfaces of the power connection piece 10 and the light connection piece 11. One end of the connecting spring 3 is sleeved on the top surface of the protective component 12.

[0034] It should be noted that the protective component 12 is used to cover one end of the injection pen body 20 to provide shock absorption and protection for the needle of the injection pen, and the protective component 12 is made of transparent material.

[0035] The flow guide 13 includes an annular connecting piece 14 and two flow guide pieces 15. One end of each of the two flow guide pieces 15 is integrally fixedly connected to both ends of the annular connecting piece 14, and the other end of each of the two flow guide pieces 15 is respectively attached to the surface of the power connection piece 10 and the light connection piece 11.

[0036] It should be noted that the annular connecting piece 14 and the two guide pieces 15 are connected as a single unit in order to facilitate the connection of the power connecting piece 10 and the light connecting piece 11 so that the circuit of the disinfection lamp 5 is complete, thereby controlling the opening and closing of the disinfection lamp 5.

[0037] The power supply component includes a mounting button 16, a connecting piece 17, and multiple batteries 18. The mounting button 16 is threaded into the inside of one end of the pen cap body 1. The bottom end of the mounting button 16 is in contact with the positive output end of the battery 18. The connecting piece 17 is located inside the connecting groove 2. One end of the connecting piece 17 is in contact with the outer surface of the mounting button 16, and the other end of the connecting piece 17 is in contact with the top surface of the power connection piece 10.

[0038] It should be noted that multiple batteries 18 are button batteries 18, and the button batteries 18 can be 3V or higher voltage button batteries 18, such as the CR2032 model button battery 18, to provide energy support for the disinfection lamp 5.

[0039] In one specific embodiment, the top of the battery 18 is the positive terminal, and the bottom of the battery 18 is the negative terminal. This allows the negative terminal at the bottom of the battery 18 to directly contact the negative terminal connecting piece 7, while the positive terminal of the battery 18 conducts positive electrical output through the cooperation of the mounting button 16 and the connecting piece 17. At this time, the positive terminal of the disinfection lamp 5 is controlled by the connecting control component 9, so that when the injection pen body 20 is inserted into the pen cap assembly, the disinfection lamp 5 turns on to disinfect the needle of the injection pen body 20; otherwise, the disinfection lamp 5 is disconnected and stops working.

[0040] It should be noted that the bottom of the mounting button 16 is conductive, while the top of the mounting button 16 is insulated. The purpose of this design is that when the bottom of the mounting button 16 contacts the top of the battery 18, the positive current of the battery 18 is guided to the power connection piece 10 through the connecting piece, and then connected to the light connection piece 11 through the current guide 13, so that the circuit of the disinfection lamp 5 is complete and the disinfection work is realized. When the injection pen body 20 is pulled out, the protective piece 12 is subjected to the elastic force of the connecting spring 3, which causes the two current guide pieces 15 to disconnect from the power connection piece 10 and the light connection piece 11, resulting in an open circuit of the disinfection lamp 5 and thus stopping its work.

[0041] In the specific implementation process, such as Figures 1-3 as well as Figure 5 As shown, the present invention provides an injection pen, including a pen cap assembly and an injection pen body 20. One end of the injection pen body 20 is inserted into the pen cap assembly, and the surface of one end of the injection pen body 20 is in contact with the inner sidewall of the protective member 12.

[0042] It should be noted that the elastic force of the connecting spring 3 is less than the insertion force of one end of the injection pen body 20 into the pen cap assembly.

[0043] The working principle provided by this utility model is as follows:

[0044] When the injection pen body 20 is placed inside the pen cap assembly, one end of the injection pen body 20 will first drive the protective component 12, the annular connecting piece 14 and the two guide pieces 15 on its surface to move into the pen cap body 1. At this time, when one end of the injection pen body 20 is inserted into the pen cap assembly, the annular connecting piece 14 and the two guide pieces 15 will respectively contact the surfaces of the power connection piece 10 and the light connection piece 11, so that the circuit of the disinfection lamp 5 is complete and the disinfection work is realized. Through the mutual linkage and cooperation between the above-mentioned device components, the disinfection work of the injection needle at one end of the injection pen body 20 is completed.

[0045] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
