[0002] Ultraviolet (UV) germicidal lamps, as highly efficient disinfection devices, are widely used for disinfection of air, object surfaces, and water. Traditional UV germicidal lamps are typically connected to the power socket using screws. While this connection method ensures the lamp's stability and reliability to some extent, the installation and disassembly process is cumbersome, requiring specialized tools. This not only increases maintenance costs but also reduces the ease of assembly and disassembly. Especially in situations requiring frequent lamp replacement or maintenance, this cumbersome installation method has become a significant factor limiting its widespread application.

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a germicidal lamp that can be quickly assembled and disassembled.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A quick-assembly and disassembly germicidal lamp includes a left lamp head, a right lamp head, and a glass lamp tube. The left end of the glass lamp tube is closed by a left clamping part, and the right end is closed by a right clamping part. The left lamp head has a left slot for fixing the left clamping part, and the right lamp head has a right slot for fixing the right clamping part. The right lamp head has four lamp feet. The left clamping part has a left filament, and the two electrodes of the left filament are each connected to one of the lamp feet through an external wire. The right clamping part has a right filament, and the two electrodes of the right filament are each connected to one of the lamp feet through an internal wire. The right lamp head includes a lamp head body with the right slot, a first insertion part and a second insertion part that protrude axially on the right end face of the lamp head body, the first insertion part and the second insertion part are connected together radially, the protrusion length of the first insertion part is less than the protrusion length of the second insertion part, and positioning recesses are provided on both the front and rear sides of the connection between the first insertion part and the second insertion part.

[0006] Two of the lamp connecting feet are fixed to the right end face of the lamp holder body and correspond to two positioning recesses respectively, while the other two lamp connecting feet are fixed to the right ends of the first and second inserts respectively.

[0007] In this invention, both the left and right lamp heads are made of ceramic material.

[0008] In this invention, the right-side cross-sectional shape of the positioning recess is a slightly curved shape.

[0009] In this invention, the outer conductor is located on the outside of the glass lamp tube, and the glass lamp tube is provided with a cable fixing structure to prevent the outer conductor from moving around.

[0010] In this utility model, the cable fixing structure includes at least one wire fixing ring fitted on the glass tube, and the outer wire is fixed and tightly attached to the outer surface of the glass tube by the wire fixing ring.

[0011] In this utility model, each of the lamp feet includes a lamp foot body, a lamp foot limiting part, and a power connecting foot connected sequentially along the axial direction. The lamp foot body is fixed inside the lamp head body, and the left end of the lamp foot body extends into the right slot. The lamp foot limiting part is used to abut against the right end face of the lamp head body, the first insertion part, or the second insertion part.

[0012] In this utility model, a reinforcing limiting part is provided on the outer surface of the lamp base body and located inside the lamp head body.

[0013] In this invention, the right end of the power connection pin is a lamp pin inlet with a diameter that gradually decreases from left to right.

[0014] In this utility model, the side of the first insertion part facing away from the second insertion part and the side of the second insertion part facing away from the first insertion part are both convex arc surfaces connected to the outer peripheral surface of the lamp head body, and the diameter of the convex arc surface is the same as the diameter of the outer peripheral surface of the lamp head body.

[0015] In this utility model, the left and right sides of the first insertion part and the second insertion part are both planes.

[0028] Reference Figure 1-7A quick-assembly and disassembly germicidal lamp includes a left lamp head 1, a right lamp head 2, and a glass lamp tube 3. The glass lamp tube 3 is a quartz glass tube. The left end of the glass lamp tube 3 is closed by a left clamping part 31, and the right end is closed by a right clamping part 32. The left lamp head 1 has a left slot 10 for fixing the left clamping part 31, and the right lamp head 2 has a right slot 20 for fixing the right clamping part 32. The right lamp head 2 has four lamp pins 4 for connecting to the power supply. 1. A left filament 5 is provided, and the two electrodes of the left filament 5 are respectively connected to a lamp base 4 through an external wire 6; a right filament 7 is provided on the right clamping part 32, and the two electrodes of the right filament 7 are respectively connected to a lamp base 4 through an internal wire 8. The lamp base 4 is used to connect an external power supply lamp holder, so that the power supply lamp holder can supply power to the left filament 5 and the right filament 7, so that the left filament 5 and the right filament 7 work to generate ultraviolet light inside the glass lamp tube 3.

[0029] Furthermore, the right lamp head 2 includes a lamp head body 21 with the right slot 20, a first insertion part 22 and a second insertion part 23 protruding axially on the right end face of the lamp head body 21, the first insertion part 22 and the second insertion part 23 being connected together radially, the protrusion length of the first insertion part 22 being less than the protrusion length of the second insertion part 23, and positioning recesses 24 being provided on both the front and rear sides of the connection between the first insertion part 22 and the second insertion part 23; wherein two lamp connecting feet 4 are fixed on the right end face of the lamp head body 21 and respectively correspond to the two positioning recesses 24, wherein the two lamp connecting feet 4 are used to connect the two electrodes of the right filament 7; the other two lamp connecting feet 4 are respectively fixed on the right ends of the first insertion part 22 and the second insertion part 23, and the other two lamp connecting feet 4 are used to connect the two electrodes of the left filament 5. During installation, the lamp head body 21 is inserted into the lamp head slot of the power lamp holder, while the first insertion part 22 and the second insertion part 23 are respectively inserted into the first slot and the second slot inside the lamp head slot, thereby achieving the purpose of inserting the right lamp head 2 into the power lamp holder. Moreover, since the protrusion lengths of the first insertion part 22 and the second insertion part 23 are different, the second insertion part 23 can be inserted more deeply into the power lamp holder. This allows the right lamp head 2 to be better positioned and matched with the power lamp holder using this staggered structure, and the stability of the germicidal lamp after installation is relatively high. In addition, the two lamp head positioning parts inside the lamp head slot are respectively embedded in the two positioning recesses 24, which further improves the stability of the germicidal lamp after installation.

[0030] In this embodiment, both the left lamp head 1 and the right lamp head 2 are made of ceramic material, thereby giving the left lamp head 1 and the right lamp head 2 an insulating function.

[0031] In this embodiment, the side cross-sectional shape of the positioning recess 24 is a minor arc shape, which has relatively less contact surface compared to the major arc shape, making it easier for the lamp head positioning part to be inserted into the positioning recess 24.

[0032] In this embodiment, the inner wire 8 is located inside the right slot 20, and the outer wire 6 is located on the outside of the glass tube 3. Currently, the metal wire of the outer wire 6 is usually connected to the electrodes of the lamp base 4 and the left filament 5 by welding. After welding, the outer wire 6 is usually not taut, so the part exposed on the outside of the glass tube 3 is prone to shaking during the movement of the germicidal lamp, causing the outer wire 6 to be snagged and broken by foreign objects. In order to solve this technical problem, the glass tube 3 is provided with a cable fixing structure to prevent the outer wire 6 from moving randomly. The cable fixing structure includes at least one wire fixing ring 9 fitted on the glass tube 3. The outer wire 6 is fixed and pressed against the outer surface of the glass tube 3 by the wire fixing ring 9, and cannot be moved at will, thereby reducing the risk of the outer wire 6 being moved and pulled and damaged by foreign objects during transportation.

[0033] In this embodiment, each of the power-connecting lamp feet 4 includes a lamp foot body 41, a lamp foot limiting part 42, and a power-connecting foot 43 connected sequentially along the axial direction. The lamp foot body 41 is fixed inside the lamp head body 21, and the left end of the lamp foot body 41 extends into the right slot 20. The lamp foot limiting part 42 is used to abut against the right end face of the lamp head body 21, the first insertion part 22, or the second insertion part 23 to better position and install it on the right lamp head 2.

[0034] In this embodiment, to further restrict the movement of the lamp contact pin 4 relative to the right lamp holder 2, a reinforcing limiting part 44 is provided on the outer surface of the lamp contact pin body 41, located inside the lamp holder body 21. Additionally, to facilitate the insertion of the lamp contact pin 4 into the corresponding conductive position of the power supply socket for conduction, the right end of the lamp contact pin 43 is a lamp contact inlet head 45 with a diameter that gradually decreases from left to right.

[0035] In this embodiment, the side of the first insertion part 22 facing away from the second insertion part 23 and the side of the second insertion part 23 facing away from the first insertion part 22 are both convex arc surfaces connected to the outer peripheral surface of the lamp head body 21. The diameter of the convex arc surface is the same as the diameter of the outer peripheral surface of the lamp head body 21, so that the first insertion part 22 and the second insertion part 23 can also match the groove wall of the lamp head slot together with the lamp head body 21, further improving the positioning and installation effect.

[0036] In this embodiment, both the left and right sides of the first insertion part 22 and the second insertion part 23 are flat. The front side of the first insertion part 22 and the front side of the second insertion part 23 are flush to form a front assembly surface, and the rear side of the first insertion part 22 and the rear side of the second insertion part 23 are flush to form a rear assembly surface, so that the first insertion part 22 and the second insertion part 23 can be better integrally formed.

[0037] In this embodiment, the right slot 20 is provided with a right fixing seat 100 fixed with glue. The right fixing seat 100 is provided with a right axial through hole along the axial direction. The right axial through hole includes a right mounting groove 101, a right positioning groove 102 and a right wiring groove 103 connected from left to right. The right end of the glass lamp tube 3 is inserted and fixed in the right mounting groove 101 and the right clamping part 32 is positioned and inserted in the right positioning groove 102. The right end of the glass lamp tube 3 and the right clamping part 32 are both fixed to the right fixing seat 100 by glue connection. The two electrodes of the inner wire 8 and the right filament 7 are both located in the right wiring groove 103. Furthermore, at least one right circumferential limiting part 26 protrudes from the groove wall of the right slot 20, and at least one right circumferential limiting groove 104 is provided on the outer circumferential surface of the right fixing seat 100. Each right circumferential limiting groove 104 is embedded with one right circumferential limiting part 26, thereby limiting the right fixing seat 100 to rotate circumferentially relative to the right lamp head and ensuring the stability of their combination.

[0038] In this embodiment, a left fixing seat 200, which is fixed with adhesive, is provided in the left slot 10. The left fixing seat 200 is fixed in the left slot 10 by adhesive connection. Furthermore, at least one left circumferential limiting part protrudes from the slot wall of the left slot 10, and at least one left circumferential limiting groove is provided on the outer circumferential surface of the left fixing seat 200. One left circumferential limiting part is embedded in each left circumferential limiting groove, thereby limiting the circumferential rotation of the left fixing seat 200 relative to the left lamp head and ensuring the stability of their combination. The left fixing seat 200 is provided with a left axial through hole along the axial direction. The left axial through hole includes a left wiring groove 201, a left positioning groove 202, and a left mounting groove connected sequentially from left to right. The left end of the glass lamp tube 3 is inserted and fixed in the left mounting groove, and the left clamping part 31 is positioned and inserted in the left positioning groove 202. The left end of the glass lamp tube 3 and the left clamping part 31 are both fixed to the left fixing seat 200 by adhesive connection.

[0039] Furthermore, the outer peripheral surface of the right fixing base 100 is provided with two right wire-passing grooves 106 corresponding to the two external conductors 6 respectively. The right end of the right wire-passing groove 106 is connected to the right wiring groove 103, and the left end passes through the left end of the right fixing base 100. The outer peripheral surface of the left fixing base 200 is provided with two left wire-passing grooves 203 corresponding to the two external conductors 6 respectively. The left end of the left wire-passing groove 203 is connected to the left wiring groove 201, and the right end passes through the right end of the left fixing base 200. The left end of the external conductor 6 enters the left wiring groove 201 through the left wire-passing groove 203 and connects to the electrode of the left filament 5. The right end enters the right wiring groove 103 through the right wire-passing groove 106 and connects to the corresponding lamp pin 4.

[0040] Furthermore, the left fixed base 200 has an adjustment receiving groove 204 on its outer circumferential surface at its left end. An adjustment seat 300 for adjusting the tightness of the external wire 6 is inserted radially into the adjustment receiving groove 204. The adjustment seat 300 has an adjustment threading hole 301 for the external wire to pass through. The external wire 6 has a right wire protrusion 61 that abuts against the wall of the right wiring groove 103 and a left wire protrusion 62 that abuts against the left end face of the adjustment seat 300. The bottom of the adjustment seat 300 is raised. The system includes an adjustment positioning part 302, with at least two adjustment inserts 303 arranged from left to right on both its front and rear sides. An adjustment receiving groove 204 contains an adjustment locking groove 205 for the adjustment positioning part 302 to insert into. The front and rear walls of the adjustment locking groove 205 each have multiple adjustment fixing grooves 206 arranged from left to right, with the number of adjustment fixing grooves 206 exceeding the number of adjustment positioning parts 302. Each adjustment insert 303 is inserted into one adjustment fixing groove 206. By inserting the adjustment insert 303 into different positions of the adjustment fixing grooves 206, the tightness of the external conductor 6 can be adjusted.

[0041] In this embodiment, the right conductor protrusion 61 and the left conductor protrusion 62 can be formed by knotting the outer conductor 6, or they can be formed by injection molding of adhesive protrusions on the outer conductor 6 sheath, preferably adhesive protrusions.

[0042] In this embodiment, in order to facilitate workers to insert or remove the adjustment seat 300, the adjustment seat 300 is provided with a finger hole 304, so that workers can lift the adjustment seat 300 by hand or tool.
