Description

Technical Field

[0001] The invention relates to the technical field of lamp lighting, and in particular to a stage lamp with a water and grease removal device. Background Art

[0002] The Chinese utility model patent (CN217109266U) discloses a stage lamp with a support arm having both waterproof and heat dissipation functions. Figure 1 The following contents were disclosed:

[0003] In a preferred embodiment of the utility model, the second box body includes an upper end cover and a lower end cover that are interlocked, and a first waterproof strip is provided between the upper end cover and the lower end cover. By disassembling the second box body, when maintenance is required, the components inside the second box body can be maintained by simply removing the upper end cover, which is convenient and quick.

[0004] In a preferred embodiment of the utility model, an absorbent is fixedly arranged inside the second box body. Since there is water vapor inside the lamp body, it will cool down to form water vapor after flowing through the second box body driven by the hot air inside the lamp body and exchanging heat with the inner wall. The absorbent is arranged to absorb the water vapor so that the inside of the circulating airflow channel is kept dry. Preferably, the absorbent can be at least one of a sponge and a desiccant. The absorbent is fixedly installed on the bottom end surface inside the second box body.

[0005] The defect brought by the above technical solution is that the desiccant has a certain service life. When the water absorption capacity of the desiccant is saturated, the desiccant needs to be replaced, otherwise the product will be affected by moisture and deterioration, which will affect the quality stability and performance. However, the absorbent is fixedly installed at the bottom of the second box body of the U-shaped support arm, which brings many inconveniences to the replacement of the desiccant. When replacing, the outer shell of the U-shaped support arm must be disassembled first, and then the end cover is removed. This replacement method is particularly cumbersome. Summary of the invention

[0006] The present invention is to solve one of the above-mentioned technical problems and provide a stage lamp with a water and grease removal device, which can remove moisture and grease inside the lamp body, thereby reducing the risk of internal parts of the lamp body being damaged by moisture, ensuring the stability and performance of the product and extending the service life of the product.

[0022] It should be noted that, in the absence of conflict, the embodiments in the present application and the features described in the embodiments may be combined with each other. The present application is further described in detail below in conjunction with the drawings and specific embodiments.

[0023] As attached Figure 1 To Attachment Figure 4As shown, a stage lamp with a water and grease removal device includes a case 1, a U-shaped support arm 2 and a lamp head 3. The case 1 is pivotally connected to the bottom of the U-shaped support arm 2 through a first pivot axis 10, and both sides of the lamp head 3 are pivotally connected to the inner side of the U-shaped support arm 2 through a second pivot axis 20. A through hole 30 is provided at the center of each of the first pivot axis 10 and the second pivot axis 20. The internal space of the case 1 is connected to the internal space of the U-shaped support arm 2 through the through hole 30 of the first pivot axis 10, and the internal space of the lamp head 3 is connected to the internal space of the U-shaped support arm 2 through the through hole 30 of the second pivot axis 20. The dewatering and degreasing device includes a storage box 4 and a fan 5 which are arranged in the internal space of the U-shaped support arm 2. The storage box 4 is provided with a mesh hole 41. An absorbent for absorbing water vapor and vaporized grease is placed in the storage box 4. The fan 5 is used to drive the internal gas of the lamp body to flow and flow through the storage box 4; the fan can accelerate the gas flow inside the lamp. When the gas flows through the absorbent, the absorbent can adsorb the remaining water vapor and vaporized grease in the gas, thereby drying the internal gas of the lamp, thereby reducing the risk of internal parts of the lamp body being damaged by moisture, ensuring the stability and performance of the product, and extending the service life of the product.

[0024] In addition, the absorbents are centrally stored in the storage box 4. When replacement is needed, the storage box with new absorbents can be replaced or the absorbents in the storage box can be replaced. Compared with the prior art, the water and grease removal device created by the present invention has higher replacement efficiency.

[0025] As attached Figure 3 and attached Figure 4 As shown, the inner space of the U-shaped support arm 2 is provided with a fixing plate 6, and the fixing plate 6 is provided with a vent 61, one end of the fixing plate 6 is connected to the storage box 4, and the vent of the fixing plate 6 is opposite to the storage box 4; the fan 5 has an air inlet 51 and an air outlet 52, the other end of the fixing plate 6 is connected to the fan 5, and the vent 61 of the fixing plate 6 is opposite to the air inlet 51 of the fan 5; the fan 5 can drive the gas inside the lamp body to pass through the mesh hole 41, the vent 61, the air inlet 51 and the air outlet 52 in sequence. The storage box 4 and the fan 5 can be fixedly installed in the inner space of the U-shaped support arm 2 at the same time through the fixing plate 6, so that the water removal and grease removal device forms a modular component, thereby improving the assembly efficiency of the lamp.

[0026] As attached Figure 4 As shown, the fixing plate 6 is provided with a threaded column 62, a first fixing hole 63 and a second fixing hole 64. The threaded column 62 of the fixing plate 6 is connected to the storage box 4 by a first screw, the first fixing hole 63 of the fixing plate 6 is connected to the fan 5 by a second screw, and the second fixing hole 64 of the fixing plate 6 is connected to the inside of the U-shaped support arm 2 by a second screw. Figure 3 As shown, the U-shaped support arm 2 includes an arm body 21 and a side end cover 22. The arm body 21 has an opening 200 for exposing the water and grease removal device. The opening 200 of the arm body 21 is sealed and connected to the side end cover 22 via a waterproof seal 7 to close the opening 200.

[0027] The replacement steps of the water-removing and grease-removing device: when replacing, first disassemble the side end cover 22 to expose the water-removing and grease-removing device; then remove the second screw to remove the water-removing and grease-removing device; then remove the first screw to replace the storage box 4 with a new absorber or replace the absorber in the storage box 4; finally reinstall them to complete the replacement. Compared with the prior art, the above replacement method is faster and more convenient, and the replacement can be completed without disassembling the large parts of the lamp body, reducing the disassembly and assembly steps, and greatly improving the replacement efficiency.

[0028] As attached Figure 5 As shown, the fan 5 is preferably a turbofan, which has the advantages of high efficiency, controllability, reliability, strong adaptability and reduced noise.

[0029] In this embodiment, the absorbent is a plurality of granular molecular sieves, i.e., microporous aluminosilicate crystals. Compared with other desiccants, molecular sieves have the characteristics of uniform pore size and extremely high specific surface area, good thermal stability, strong adsorption performance, large internal surface area, high strength, etc. Furthermore, they have strong water absorption, and even at a high temperature (the reduction condition of molecular sieves is to bake at 200°C for 2 hours, but the temperature inside the lamp body is far from reaching that), a large air velocity and a low water content, they still have a fairly high water absorption capacity.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various equivalent changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
