[0035] Refer to Figure 1, a lamp cap structure, comprising: a wire 100, a base 200, a lamp housing 300 and a sealing structure 600. A lamp bead 500 is arranged at the end of the wire 100; the base 200 is sleeved on the outer periphery of the wire 100; the base 200 includes a housing part 210 and a core part 220. The core part 220 surrounds the wire 100, and the housing part 210 is sleeved on the outer periphery of the core part 220; wherein, the core part 220 is flexible; the lamp housing 300 is sleeved on the outer periphery of the lamp bead 500, the housing part 210 is connected to the lamp housing 300, and the housing part 210 and the lamp housing 300 cooperate to surround the lamp bead 500; the lamp housing 300 has light transmittance and can make the light emitted by the lamp bead 500 irradiate outside the lamp housing 300; the sealing structure 600 is arranged on the base 200, and the sealing structure 600, the base 200 and the lamp housing 300 can cooperate to seal the lamp bead 500. After the base 200 cooperates with the lamp housing 300 to surround the lamp bead 500, and the sealing structure 600 cooperates with the base 200 and the lamp housing 300 to achieve the sealing effect on the lamp bead 500, the lamp bead 500 can obtain the protection effect of the base 200 and the lamp housing 300 on it. Therefore, it can effectively ensure that the lamp bead 500 can smoothly and stably perform the lighting operation. The base 200 contacts and connects with the wire 100 through the flexible core part 220. Therefore, when the wire 100 and the base 200 are relatively bent or folded, the base 200 can provide a more sufficient avoidance position for the wire 100, and the wire 100 can be in flexible contact with the base 200 when bent. Therefore, it can effectively reduce the stress concentration problem suffered by the wire 100, and then achieve the effect of slowing down or avoiding damage to the wire 100. The flexible core part 220 can also adaptively deform according to the actual shape of the wire 100, so as to completely and comprehensively seal the gap between the wire 100 and the base 200. Therefore, it can effectively improve the overall waterproof performance. And, since the sealing structure 600 can cooperate with the base 200 and the lamp housing 300 to seal the lamp bead 500, it can also effectively achieve the waterproof effect on the lamp bead 500, so as to ensure that the lamp cap can have stable and effective waterproof performance, and then slow down or avoid problems such as damage or failure caused by corrosion of the wire 100 and the pins of the lamp bead 500 due to rainwater infiltration and other problems, and reduce corresponding circuit hidden dangers such as short circuits.

[0036] In some embodiments, referring to Figure 2 , a clamping structure 350 is arranged between the housing part 210 and the lamp housing 300, and the housing part 210 and the lamp housing 300 are clamped and connected through the clamping structure 350. The clamping structure 350 can not only enable the housing part 210 and the lamp housing 300 to be smoothly connected to each other, but also has the advantage of convenient installation. Therefore, it can provide convenience for the assembly process of string lights.

[0037] It can be expected that the connection between the housing part 210 and the lamp housing 300 can also be a glue connection. Therefore, the connection method between the housing part 210 and the lamp housing 300 is not unique, but can be adjusted according to the actual situation and is not limited here.

[0038] In some embodiments, referring to Figure 3 , the snap-fit structure 350 includes a plurality of snap tabs 357 provided on the lamp housing 300, and a slot 354 is provided between two adjacent snap tabs 357; the inner side of the end of the housing part 210 has a protruding portion and can be snap-fitted into the slot 354. The snap tabs 357 and the slots 354 can form a plurality of concave-convex structures for snap-fitting on the lamp housing 300, so that the protruding portion on the housing part 210 can be smoothly snap-fitted to the concave-convex structure on the lamp housing 300, and then the snap-fitting action can be completed quickly and smoothly, and the lamp head can be conveniently assembled and formed.

[0039] Specifically, there are two snap tabs 357, and the two slots 354 are located between the two snap tabs 357.

[0040] In some embodiments, referring to Figure 2 , the sealing structure 600 includes a sealing plug 650, and the sealing plug 650 is fixedly installed at one end of the base 200 away from the lamp housing 300. One end of the base 200 close to the lamp housing 300 will achieve a sealing effect by the mutual pressing between the base 200 and the sealing plug 650, and the end of the base 200 away from the lamp housing 300 will be sealed by the sealing plug 650, so that the internal space between the base 200 and the lamp housing 300 can be comprehensively sealed, and then the comprehensive protection of the lamp beads 500 can be realized.

[0041] It can be expected that the base 200 or the lamp housing 300 can be made of a heat-conducting material, such as plastic, so as to avoid damage to the lamp beads 500 due to overheating. The specific implementation method is not unique, but can be adjusted according to the actual situation and is not limited here.

[0042] In some embodiments, referring to Figure 2 , the wire 100 is provided with a positioning plug 630, the positioning plug 630 is located at the connection between the wire 100 and the lamp beads 500, and a positioning structure 250 for connecting and fixing the positioning plug 630 is provided in the base 200. The positioning structure 250 can fix the wire 100, the lamp beads 500 and the base 200 to each other through the positioning plug 630, so as to ensure that the lamp beads 500 are stably and accurately installed in the base 200 and the lamp housing 300, and avoid the problems of shaking and position disorder of the lamp beads 500.

[0043] In some embodiments, referring to Figure 4, the positioning structure 250 includes a positioning step 253 provided on the inner core portion 220. One end of the positioning plug 630 can abut against the positioning step 253, and the lamp bead 500 is connected to the other end of the positioning plug 630. The positioning step 253 and the lamp bead 500 are respectively located at both ends of the positioning plug 630. Therefore, it can be ensured that the positioning plug 630 cannot move into the base 200 through the positioning step 253, thereby effectively preventing the problem that the lamp bead 500 moves wrongly into the base 200 and causes the light to be blocked, and ensuring that the lamp head can emit light stably.

[0044] In some embodiments, referring to Figure 4 , the positioning structure 250 includes a card slot 354 provided on the inner core portion 220, and the positioning plug 630 can be snapped into the card slot 354. The snap connection between the card slot 354 and the positioning plug 630 can stably fix the positioning plug 630 in the base 200, so that the lamp bead 500 connected to the positioning plug 630 can also stably maintain its relative position relationship with the base 200 and the lamp housing 300, and further ensure that the light emitted by the lamp bead 500 can be smoothly emitted outside the base 200.

[0045] In some embodiments, referring to Figure 5 , the sealing structure 600 includes a waterproof plug 670. The waterproof plug 670 is provided with a snap ring 673 and a sealing flange 671. The waterproof plug 670 is snapped onto the base 200 through the snap ring 673 and the sealing flange 671 blocks the gap between the base 200 and the wire 100; the waterproof plug 670 is provided with a wire groove 675. After the waterproof plug 670 is snapped onto the base 200 through the snap ring 673, the sealing flange 671 can be positioned at the bottom end of the base 200, and the sealing effect between the base 200 and the wire 100 can be achieved through the sealing flange 671, thereby effectively improving the waterproof performance of the lamp head. The wire groove 675 can not only enable the wire 100 to pass through the waterproof plug 670 smoothly, but also relatively position the wire 100 and the waterproof plug 670, and further ensure that the waterproof effect between the wire 100 and the base 200 can be accurately achieved.

[0046] Specifically, the snap ring 673 is in the shape of a groove, and a rubber ring for waterproofing is installed inside it, so as to effectively improve its waterproof performance.

[0047] In some embodiments, referring to Figure 5, the closed structure 600 includes filled glue, which is poured into the base 200 from the end of the base 200 away from the lamp housing 300. The filled glue can be cured and block the gap between the base 200 and the wire 100. The filled glue can enter the gap between the base 200 and the wire 100 by means of glue injection and fill the gap, so as to successfully achieve the effect of closing the lamp beads 500. Since the filled glue is in a liquid state at this time, its ductility can effectively adapt to the shape of the gap between the wire 100 and the base 200, and after the filled glue is cured, it can close the actual gap shape between the wire 100 and the base 200, and then a comprehensive and effective sealing and waterproof effect can be achieved through the cured filled glue.

[0048] Specifically, in the solution of this application, referring to Figure 2 , the closed structure 600 can achieve the sealing and waterproof effect through the mutual extrusion between the outer shell part 210 and the inner core part 220; or, referring to Figure 5 , the solution of this application can also achieve the sealing and waterproof effect through filled glue. Therefore, in the solution of this application, the specific sealing and waterproof method is not unique, but can be adjusted accordingly according to the actual situation, and is not limited here.

[0049] In some embodiments, referring to Figure 1 , the rigidity of the outer shell part 210 is greater than that of the inner core part 220. The outer shell part 210 with higher rigidity is located outside, so it can effectively protect the inner core part 220 and the wire 100 inside through its rigidity.

[0050] Specifically, the outer shell part 210 is made of hard plastic, and the inner core part 220 is made of soft plastic. Of course, the outer shell part 210 and the inner core part 220 can also be composed of other components. The specific implementation method is not unique, but can be adjusted accordingly according to the actual situation, and is not limited here.

[0051] In the second aspect of the present utility model, an embodiment of a string light is provided, including the above lamp head structure. After the base 200 cooperates with the lamp housing 300 to surround the lamp beads 500, and the sealing structure 600 cooperates with the base 200 and the lamp housing 300 to achieve the sealing effect on the lamp beads 500, the lamp beads 500 can be effectively protected by the base 200 and the lamp housing 300. Therefore, it can effectively ensure that the lamp beads 500 can smoothly and stably perform the lighting operation. The base 200 contacts and connects with the wire 100 through the flexible inner core part 220. Therefore, when the wire 100 and the base 200 are relatively bent or folded, the base 200 can provide a more sufficient avoidance position for the wire 100, and the wire 100 can be in flexible contact with the base 200 when bent. Therefore, the stress concentration problem on the wire 100 can be effectively reduced, and the effect of slowing down or avoiding damage to the wire 100 can be achieved. The flexible inner core part 220 can also be adaptively deformed according to the actual shape of the wire, so as to completely and comprehensively seal the gap between the wire 100 and the base 200. Therefore, the overall waterproof performance can be effectively improved. Moreover, since the sealing structure 600 can cooperate with the base 200 and the lamp housing 300 to seal the lamp beads 500, the waterproof effect on the lamp beads 500 can also be effectively achieved, so as to ensure that the lamp head has stable and effective waterproof performance, and then slow down or avoid problems such as damage or failure caused by the corrosion of the wire 100 and the pins of the lamp beads 500 due to rainwater infiltration and other problems, and reduce corresponding circuit hidden dangers such as short circuits.

[0052] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0053] The embodiments of the present utility model have been described in detail above with reference to the drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art in the said technical field, various changes can be made without departing from the purpose of the present utility model.
