Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0033] The utility model discloses a light-emitting device for rotating and sending liquid upward, which is particularly applicable to the field of handicrafts.

[0034] See also Figure 1-Figure 5, the device includes: a motor 10, a first magnetic part 20, an inner chassis 30, a chamber shell 40, a second magnetic part 50, a rotating module 60, and a light-emitting component 70. Among them, the motor 10 is used to output torque, and the first magnetic part 20 is connected to the output shaft of the motor 10; the inner chassis 30 is arranged above the first magnetic part 20, and the chamber shell 40 is covered on the inner chassis 30, so that the two form a sealed liquid chamber, and the liquid chamber is filled with liquid. Of course, it can be understood that by designing the chamber shell 40 into different shapes, the lamp can have different appearances. The second magnetic part 50 is rotatably installed on the top surface of the inner chassis 30, and there is a gap between the first magnetic part 20 and the second magnetic part 50, and the two together constitute a magnetic coupling device. Refer to Figure 6-Figure 7 The rotating module 60 is fixed to the second magnetic part 50, and includes a rotating wheel 61 and a rotating column 62; a plurality of rotating wheel blades 611 are arranged on the outer periphery of the rotating wheel 61; the rotating column 62 is fixed to the rotating wheel 61, and a rotating column blade 621 is arranged on the outer wall of the rotating column 62. The light emitting component 70 has a light source 71 built therein. In this embodiment, the light source 71 is a strip light belt equipped with LED lamp beads.

[0035] The blade shape and spacing of the rotating column blades 621 are not limited. In the present embodiment, the rotating column blades 621 are continuous spiral blades, which are conducive to the stable spiral upward delivery of water. In other embodiments, the rotating column blades 621 may also be intermittent spiral blades. Of course, a single blade form similar to the rotating wheel blades 611 may also be adopted. The single blades may be regularly or irregularly arranged along the axial direction of the rotating column 62, for example, m single blades are arranged in a circle every n millimeters, and the structural form of the single blade itself is not limited.

[0036] When the utility model is working: the motor 10 starts, driving the first magnetic part 20 to rotate. Since the first magnetic part 20 and the second magnetic part 50 together form a magnetic coupling device, the second magnetic part 50 is subjected to the magnetic force to rotate synchronously, and drives the rotating module 60 to rotate. The rotating wheel blades 611 around the rotating wheel 61 stir the liquid and rotate the liquid upward, mainly stirring the liquid at the bottom of the liquid chamber and causing it to spiral up. At the same time, the rotating column blades 621 on the rotating column 62 in a continuous spiral shape can drive the liquid in the middle and upper parts of the liquid chamber to spiral up steadily. The light emitted by the light source 71 penetrates the spirally rising liquid and projects a dynamic lighting effect outside the lamp.

[0037] When the height of the product is relatively high, due to the cooperation of the rotating wheel blades 611 and the rotating column blades 621, the rotating wheel blades 611 can firstly disturb the water flow at the bottom of the liquid chamber in a large area and with high efficiency, and the rotating column blades 621 cooperate to rotate and send the water flow upward stably and continuously until the top of the liquid chamber, so that the entire interior of the chamber is always filled with spirally rising water flow. In this way, the overall dynamic projection effect of the lamp is better, the atmosphere is stronger, and the user experience is better.

[0038] See also Figure 2-Figure 4 A limiting groove 41 is provided on the top of the chamber shell 40, and an annular mounting groove 613 is provided on the rotating wheel 61; the top end of the rotating column 62 is rotatably sleeved in the limiting groove 41 of the chamber shell 40, and the bottom end is provided in the annular mounting groove 613 of the rotating wheel 61, so that the rotating column 62 is limited in the radial direction.

[0039] In this way, when the rotating module 60 rotates, the two ends of the rotating column 62 will not shake forward and backward or left and right, especially the top of the rotating column 62 is not easy to deflect, which will make the spiral upward delivery of the liquid in the chamber more stable, that is, the stirring effect of the water flow is more regular, and the projection effect of the light after passing through the water flow is better, which improves the atmosphere created by the lamp. At the same time, due to the more stable rotation action, the water flow resistance of the rotating module 60 will also be reduced, reducing the energy consumption of the motor 10.

[0040] Preferably, see Fig. 9 The bottom of the second magnetic part 50 is provided with a plurality of spherical protrusions 51, and the spherical protrusions 51 abut against the surface of the inner chassis 30. In this way, the contact area between the second magnetic part 50 and the inner chassis 30 can be minimized, thereby reducing the friction resistance generated by the contact, and making the rotation of the rotating wheel 61 smoother.

[0041] Preferably, the first magnetic part 20 and the second magnetic part 50 are respectively equipped with magnetic blocks, and the opposing surfaces of the upper and lower magnetic blocks magnetically repel each other, so as to reduce the rotation resistance. Of course, the opposing surfaces of the magnetic blocks of the first magnetic part 20 and the second magnetic part 50 can also be magnetically attracted to each other, but when the two magnetic blocks attract each other, it will bring higher rotation resistance to the rotating module 60, so the magnetic repulsion method is preferred.

[0042] Preferably, see Figure 5-Figure 7 The light emitting assembly 70 further includes an isolation column 72 and a lamp cap 73. The isolation column 72 is a hollow sleeve, and the light source 71 is built in the isolation column 72. The lamp cap 73 is fixedly connected or integrally formed on the top of the isolation column 72, and the bottom of the isolation column 72 is sealed and fixed on the inner chassis 30, so that an independent sealed space is formed inside the isolation column 72 to isolate the liquid from entering, thereby isolating the liquid and the light source 71 from each other to avoid damaging the light strip.

[0043] Preferably, see Figure 8 The second magnetic part 50 is provided with a plurality of magnetic blocks along the peripheral direction, and a plurality of rotating wheel blades 611 are provided on the periphery of the rotating wheel 61. The magnetic blocks and the rotating wheel blades 611 are arranged at intervals from each other, so as to better deliver the liquid upward.

[0044] Preferably, see Figure 8 and Fig. 9 The blade surface structure of the rotating wheel blade 611 can be specifically divided into a vertical surface and a circular arc surface, the vertical surface is upright relative to the inner chassis 30, the circular arc surface is inclined relative to the inner chassis 30, and the vertical surface and the circular arc surface are smoothly integrated. This blade structure is conducive to stirring a larger area of ​​water flow, making the water flow spiral rise better and faster.

[0045] In order to enhance the atmosphere effect, the liquid in the chamber is often mixed with particles such as glitter powder, which will sink to the bottom due to its own gravity. When the rotating wheel 61 rotates, the deposited glitter powder is easily stuck at the bottom of the rotating wheel 61, affecting the movement of the rotating wheel 61. For this reason, preferably, refer to Fig. 9 The bottom end of the rotating wheel 61 is evenly provided with a plurality of notches 612 along the circumferential direction, and the notches 612 are connected to the inside of the rotating wheel 61. Thus, when the rotating wheel 61 rotates, the notches 612 are designed to provide a clearance between the rotating wheel 61 and the glitter powder sinking to the bottom, thereby avoiding the problem that the glitter powder is stuck in the rotating wheel 61 and affects the rotation.

[0046] Preferably, see Figure 8 The second magnetic part 50 is provided with a plurality of magnetic block installation grooves 52 along the peripheral direction, and the magnetic block is sealed and installed in the magnetic block installation groove 52. In this way, the magnetic block installation groove 52 can be sealed with glue, so that the magnetic block is not easy to fall off and rust.

[0047] Preferably, see Figure 6 The rotating column 62 is also provided with a plurality of through holes 622 so that the liquid can quickly fill the space formed between the rotating column 62 and the isolation column 72, thereby improving production efficiency.

[0048] Preferably, see Figure 2 The device further includes an installation box 80, and the bottom plate is covered on the top of the installation box 80, and the two enclose a cavity for accommodating various electrical components, and the motor 10 and the first magnetic part 20 are both installed in the cavity.

[0049] Preferably, the device further includes a power supply 90, a circuit board 100 and a speaker 110; the speaker 110 is placed in the cavity of the installation box 80. While the liquid rotates and the lamps emit light, the speaker 110 can play music with matching rhythm, making the overall rhythm of the device stronger and improving the user experience.

[0050] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
