[0032] 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.

[0033] Reference Figure 1 and Figure 3 The present invention provides an embodiment of a plug-in ultraviolet lamp ceramic lamp head, including a lamp base 1 and a socket 3. The lamp base 1 is provided with a switching component on the outer side of both ends, and the socket 3 is provided with a fixed connection component on the inner side.

[0034] The replacement assembly includes a connecting block 6, which is fixedly connected to the inner side of the lamp holder base 1. A connecting rod 7 is slidably connected to the inner side of the connecting block 6, and an elliptical locking block 14 is rotatably connected to the end of the connecting rod 7. A fixing block 5 is fixedly connected to the outer side of the socket 3, and a locking groove 13 is provided on the inner side of the fixing block 5. The elliptical locking block 14 is slidably connected to the inner side of the locking groove 13. By moving the connecting rod 7 towards the socket 3, the elliptical locking block 14 passes through the locking groove 13 of the fixing block 5 to the other end. After rotating the elliptical locking block 14 so that it changes from horizontal to vertical, the connecting rod 7 is pulled towards the base 1, so that the elliptical locking block 14 is locked into the end of the locking groove 13, that is, the inner side of the fixing block 5, thereby achieving a stable connection of the entire lamp holder. The switching assembly also includes a locking block 11, which is fixedly connected to the inner side of the connecting block 6. A sliding groove 12 is formed on the inner side of the end of the connecting rod 7, and the locking block 11 is rotatably connected to the outer side of the sliding groove 12. After the elliptical locking block 14 engages with the end of the locking groove 13 on the fixing block 5, rotating the connecting rod 7 causes the sliding groove 12 at the end of the connecting rod 7 to slide on the outer side of the locking block 11 fixed to the connecting block 6, thus locking the locking block 11 with the end of the sliding groove 12 for a secure engagement and enhanced stability. A pull ring 10 is fixedly connected to the end of the connecting rod 7. The connecting rod 7 can be moved by holding the pull ring 10.

[0035] Reference Figure 2 and Figure 4 The fixed connection assembly includes a fixed retaining ring 8, which is fixedly connected to the inside of the socket 3. Multiple retaining blocks 16 are fixedly connected to the inside of the socket 3. A retaining ring 9 is slidably connected to the inside of the fixed retaining ring 8. Multiple sliding grooves 15 are formed on the inside of the retaining ring 9, and the multiple retaining blocks 16 are slidably connected to the inside of the sliding grooves 15. By moving the retaining ring 9 from the inside of the fixed retaining ring 8 towards the lamp holder base 1, the retaining blocks 16 on the inside of the fixed retaining ring 8 slide within the sliding grooves 15 formed on the inside of the retaining ring 9. After the retaining blocks 16 enter the sliding grooves 15, rotating the retaining ring 9 allows the retaining blocks 16 to enter the end of the sliding grooves 15, and then pushing the retaining ring 9 outwards allows the retaining blocks 16 to enter the end of the sliding grooves 15 for engagement, thereby securely installing the socket 2. The fixed connection assembly also includes spring push rods 17, with multiple spring push rods 17 positioned at the ends of multiple slide grooves 15. The ends of the spring push rods 17 are fixedly connected to the inner side of the locking ring 9. After the locking block 16 enters the end of the slide groove 15, the pushing force of the spring push rods 17 drives the inclined block 18 to securely engage the locking block 16, thereby ensuring that the locking ring 9 is securely engaged inside the fixed locking ring 8. Each end of the multiple spring push rods 17 is fixedly connected to an inclined block 18, which engages with the outer side of the locking block 16. Because the inclined block 18 is inclined, it facilitates the quick entry of the locking block 16 into the end of the slide groove 15 for engagement.

[0036] Reference Figure 1 and Figure 2 Multiple contacts 4 are slidably connected to the inside of the socket 3, and each contact 4 has a sleeve 2 fixedly connected to its end. The sliding of the contacts 4 inside the socket 3 effectively enhances the overall flexibility and adaptability. The middle part of the sleeve 2 is fixedly connected to the inside of the snap ring 9. This effectively enhances the connection stability between the sleeve 2 and the socket 3, thereby ensuring the stability of the ultraviolet lamp circuit connection and enabling the ultraviolet lamp to work normally.

[0037] Working Principle: The operation for fixing and separating the lamp head is similar. When fixing, push the connecting rod 7 with the pull ring 10, causing the elliptical locking block 14 to slide out of the locking groove 13 inside the fixing block 5. Next, rotate the connecting rod 7 to make the originally horizontal elliptical locking block 14 vertical, and then pull the connecting rod 7 towards the lamp base 1, causing the vertical elliptical locking block 14 to engage with the end of the locking groove 13. After this step, rotate the pull ring 10 to rotate the connecting rod 7, causing the locking block 11 fixed inside the connecting block 6 to slide along the slide groove 12 to its end, achieving a secure engagement and thus fixing the lamp head. When separating, the operation is reversed. Rotate the pull ring 10 to slide the locking block 11 to the other end of the slide groove 12. Because the connecting rod 7 and the elliptical locking block 14 are rotatably connected, the position of the elliptical locking block 14 does not change at this time. Subsequently, following the position of the locking block 11 at the other end of the slide groove 12, pull the pull ring 10 to push the connecting rod 7 towards the socket 3, then rotate the elliptical locking block 14 to change it from a vertical position back to a horizontal position, and then pull it out of the locking groove 13 to complete the disassembly of the lamp head.

[0038] When installing the UV lamp head, push the head 2 into the socket 3, so that the multiple contacts 4 at the front end of the head 2 are inserted into the socket 3, thus allowing the contacts 4 to enter the interior of the lamp base 1. During this process, as the head 2 goes deeper, the multiple locking blocks 16 inside the retaining ring 8 will enter the sliding groove 15 inside the retaining ring 9. Then, rotate the head 2, causing the retaining ring 9 to rotate as well. When it rotates to a specific position, that is, when the multiple locking blocks 16 slide to the bottom of the inclined block 18, due to the inclined design of the inclined block 18, the thrust generated by the sliding of the locking blocks 16 will cause the inclined block 18 to push the spring push rod 17 outward. At this time, pull the head 2 outward, and the locking blocks 16 will enter the bottom of the end of the sliding groove 15. Under the action of the spring push rod 17 pushing the inclined block 18, the retaining ring 9, with the head 2, is firmly locked inside the socket 3.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
