[0043] Embodiment 1

[0044] Referring to Figures 1 to 3 , the lamp body 1 includes a lamp housing 11 and a decorative housing 12 spliced at the upper end of the lamp housing 11. The lamp housing 11 is a tubular structure with openings at both the upper and lower ends, and the lamp housing 11 is provided with a lower section 111 connected to the bottom cover 3, an upper section 112 connected to the decorative housing 12, and a middle section 113 disposed between the lower section 111 and the upper section 112 for allowing the light of the light source 2 to penetrate outward.

[0045] The decorative housing 12 is a tubular structure with an open top (i.e., a), which includes a connecting end 121 inserted into the upper port of the lamp housing 11, a placement end 122 disposed on the connecting end 121 for arranging flower bouquets or installing the light source 2, and a plugging cylinder 123 disposed in the middle of the decorative housing 12 and arranged along its axial direction for inserting flower bouquets or accommodating the ground plug 4. The upper and lower ends of the plugging cylinder 123 extend along the central axis of the decorative housing 12 to both ends respectively, and its upper end does not exceed the decorative housing 12, and the lower end extends into the lamp housing 11 and is closed at the bottom. The lower end of the plugging cylinder 123 is closed with a conical structure, which is convenient for production and manufacturing. A plurality of connecting ribs 1211 are provided on the outer wall surface of the connecting end 121. The plurality of connecting ribs 1211 are respectively parallel to the central axis of the connecting end 121 and are arranged in an annular array. The setting of the connecting ribs 1211 can make the decorative housing 12 have a certain frictional force when inserted into the lamp housing 11, so that the decorative housing 12 and the lamp housing 11 are fixed, and at the same time, it can meet the requirements of quick disassembly.

[0046] The decorative housing 12 and the bottom cover 3 are respectively detachably disposed at the upper and lower ends of the lamp housing 11, so that the overall shape of the decorative lamp in this embodiment presents an integral structure. Of course, on the premise that the lamp housing 11 retains the upper and lower ends that can be connected to the decorative housing 12 and the bottom cover 3 as a tubular structure, it can also be set to other shapes according to the use requirements or usage scenarios, such as pentagonal, heart-shaped, square, etc.; without exception, the lamp body 1 can also be set to different colors. In addition, in order to achieve a better light transmission effect, the thickness of the middle section 113 of the inner wall of the tubular lamp housing 11 can be thinned, while the thicker lower section 111 and upper section 112 have weaker light transmission ability, so that the light diverges from the middle of the lamp housing 11 to both ends and weakens. And the lamp body 1 adopts a multi-section splicing structure, which can meet the requirements of quick disassembly and assembly, and has a simple structure and convenient operation.

[0047] Furthermore, the light source 2 is installed in the lamp housing 11 through the bottom cover 3, and is an LED lamp group 22 composed of a light-emitting body and an electric control unit. The LED lamp group 22 includes an installation bin 221 for accommodating a storage battery, an LED lamp 222 disposed on the top of the installation bin 221 and electrically connected to the storage battery, an installation plate 223 disposed at the bottom of the installation bin 221 and connected to the bottom cover 3, and a controller for controlling the storage battery to supply power to the LED lamp 222. The controller can also have the function of making the LED lamp 222 present visual effects such as flashing.

[0048] The mounting plate 223 is provided with a hatch for the battery to enter the installation bin 221 and a hatch cover 224 for opening or closing the hatch, which facilitates the replacement of the battery. A channel 2241 is formed on the hatch cover 224 for the driving switch 225 of the controller to vertically pass through and be able to move horizontally. Conceivably, words such as "0N" and "OFF" are set on the hatch cover 224 to remind the position state of the driving switch.

[0049] Furthermore, the bottom cover 3 has a cover body 31 covering the lower port part of the lamp housing 11. The cover body 31 is provided with an inner cylinder 32 and an outer cylinder 33 coaxially arranged from inside to outside in sequence. The inner cylinder 32 has a through hole 321 arranged along its axial direction, and the top end face of the inner cylinder 32 is lower than the top end face of the outer cylinder 33 to form a port 34 for positioning the mounting plate 223, so that the LED lamp group 22 is fixed on the bottom cover 3, and the user can smoothly toggle the driving switch 226 through the through hole 321. A plurality of limiting ribs 36 are arranged on the outer wall surface of the outer cylinder 33. The plurality of limiting ribs 36 are respectively parallel to the central axis of the outer cylinder 33 and are arranged in an annular array to realize the quick connection with the lower port of the lamp housing 11 and fix the LED lamp group 22 in the lamp housing 22.

[0050] Among them, the bottom cover 3 fixes the LED lamp group 22 in the lamp housing 11 so that the LED lamp 222 can be positioned at the middle position of the middle section 113 of the lamp housing 11 to achieve a more beautiful and soft light transmission effect. The battery can be selected as rechargeable or dry battery, etc.

[0051] Furthermore, a stop projection 35 is arranged along the axial direction in the through hole 321. The floor plug 4 includes a main body part 41 in a cross structure and a positioning part 42 arranged at the upper end of the main body part 41 and can be inserted into the through hole 321. A limiting groove 421 adapted to the stop projection 35 is arranged on the positioning part 42. When the positioning part 42 of the floor plug 4 is inserted into the through hole 321, the stop projection 35 is placed in the limiting groove 421 so that the floor plug 4 and the bottom cover 3 cannot rotate relative to each other, realizing the stable connection between the floor plug and the lamp body 1.

[0052] Among them, the bottom of the main body 41 is conical. By setting a cross-conical structure at the bottom of the main body 41, when the decorative lamp is inserted into the ground, the horizontal bearing area of the ground plug increases, thereby achieving better support for the decorative lamp and preventing the decorative lamp from loosening during use. The positioning portion 42 has a guide piece 43 provided at the top end of the main body 41 and having the same aperture as the through hole 321, and a stop piece 44 spaced from the guide piece 43 on the main body 41. The upper end surface of the stop piece 44 has a limit boss 441 inserted into the lower port of the through hole 321. When the positioning portion 42 of the ground plug 4 is inserted into the through hole 321, the upper end surface of the guide piece 43 abuts against the lower end surface of the drive switch 226, and the upper end surface of the stop piece 44 abuts tightly against the lower end surface of the bottom cover 3, that is, it will not interfere with the LED lamp group 22, and can ensure the stable connection between the ground plug 4 and the bottom cover 3 to prevent the lamp body from shaking.

[0053] In this embodiment, an LED lamp group 22 is provided in the lamp housing 11 of the lamp body 1 to provide illumination. The lower end of the lamp housing 11 is connected to the ground plug 4 through the bottom cover 3. The upper part of the decorative housing 12 can be selectively arranged with flower bouquets as needed to decorate the space, so that the decorative lamp of this embodiment can be fixed for use on outdoor lawns, soil, etc. to beautify the space and illuminate the environment.

[0054] Embodiment Two.

[0055] Refer to Figure 4 and 5 This embodiment is different from Embodiment One in that the ground plug 4 is received in the insertion cylinder 123 of the decorative housing 12, so that this embodiment can be placed on a place with a horizontal support surface such as a table for use. Of course, the decorative housing 12 can still be arranged with flower bouquets, and at the same time, this combination is also convenient for the transportation and sales packaging of the decorative lamp.

[0056] Embodiment Three.
