Description

Technical Field

[0001] The present invention relates to the field of waterproof stage / landscape lamps, and particularly to the field of oil mist removal systems for waterproof lamps. Background Art

[0002] Due to the structural sealing of waterproof lamps in the stage lamp industry, when the lamps are working, the temperature inside the lamps is relatively high, which will cause the lubricating oil and paint coatings on various effect components inside the lamps to vaporize. The generated oil mist gas is inside the sealed lamp cavity. After a long time, it will seriously contaminate components such as the lens of the lamp, causing the brightness and clarity of the lamp to decrease as the usage time increases. Currently, in the industry, only manual cleaning of the inside of the lamp is carried out regularly, increasing the maintenance cost. Summary of the Invention

[0003] The purpose of the present invention is to provide a blower oil removal device for waterproof lamps to solve the above problems. The technical solution of the present invention is as follows: An oil mist removal system for a waterproof lamp is arranged inside the cavity of the waterproof lamp, and includes an effect component and a blower component. The blower component includes a blowing blower for dissipating heat from the effect component, a blower device one for removing oil mist inside the lamp cavity, and a blower device two for removing oil mist inside the lamp cavity and sending air to the light-emitting lens at the same time; the blowing blower and the blower device one are respectively arranged on both sides of the effect component; The blower device one includes a blower one with an air inlet close to the effect component and an oil removal cover connected to the air inlet or air outlet of the blower one; the blower device two includes a blower two with an air outlet close to the light-emitting lens and oil removal cotton two arranged at the air inlets on both sides of the blower two.

[0004] Further, the oil removal cover is a box body including at least three oil removal surfaces.

[0005] Further, the oil removal surface is provided with oil removal cotton one.

[0006] Further, the box body is a cuboid, with five surfaces being oil removal surfaces and the sixth surface being connected to the air inlet or air outlet of the blower one.

[0007] Further, the box body includes a main body, a pressing plate one, and oil removal cotton one arranged between the main body and the pressing plate one.

[0008] Further, each surface of the main body is provided with ventilation holes.

[0009] Further, the blower device two further includes a blower fixing frame for installing the blower two and a pressing plate two for fixing the oil removal cotton two.

[0010] Further, the blower device two further includes a wind guiding member connected to the air outlet of the blower two.

[0011] Further, the air guiding member is welded to the fan fixing frame.

[0012] Further, it further includes a wind pressure sensor disposed at the air outlet of the blower one or the blower two for monitoring the air volume.

[0013] Compared with the traditional technical solution, the advantages of this technical solution are as follows: on the one hand, through the blowing fan and the fan device one distributed on both sides of the effect component, the oil mist generated by the oil mist source - the effect component inside the waterproof lamp is concentratedly directionally guided and filtered, and the oil removal effect is much better than that of the conventional oil mist removal at other positions inside the lamp cavity; on the other hand, at the light-emitting lens where the oil mist has the greatest impact, the fan device two is reoriented for oil mist filtration, so that the air blown towards the light-emitting lens does not contain oil mist, and at the same time, it can also solve the problem that due to the large temperature difference between the inner and outer surfaces of the light-emitting lens when the waterproof lamp is working, water mist is easily generated on the inner surface of the light-emitting lens.

Embodiment

[0020] To make the technical problems solved by the present invention, the technical solutions adopted, and the achieved technical effects clearer, the following further describes in detail the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0021] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0022] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "over", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under", and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0023] As shown in the attached Figure 1 As shown, an oil mist removal system for a waterproof lamp is provided in the cavity 100 of the waterproof lamp, and includes an effect component 3 and a fan component. The fan component includes a blowing fan 21 for dissipating heat from the effect component, a first fan device 22 for removing oil mist from the inner cavity of the lamp, and a second fan device 23 for removing oil mist from the inner cavity of the lamp and sending air to the light-emitting lens at the same time; the blowing fan 21 and the first fan device 22 are respectively arranged on both sides of the effect component 3; The first fan device 22 includes a blower one 221 with an air inlet close to the effect component 3, and an oil removal cover 222 connected to the air inlet or air outlet of the blower one 221; the second fan device 23 includes a blower two 231 with an air outlet close to the light-emitting lens 4, and oil removal cotton two 232 arranged at the air inlets on both sides of the blower two 231.

[0024] Compared with the traditional technical solution, the advantages of this oil mist removal system are as follows: On the one hand, the system guides and filters the oil mist generated by the oil mist source - effect component 3 in the cavity 100 of the waterproof lamp in a concentrated direction through the blowing fan 21 and the first blower device 22 distributed on both sides of the effect component. The oil removal effect is much better than that of the conventional oil mist removal at other positions in the cavity 100 of the waterproof lamp. Specifically, the air outlet of the blowing fan 21 and the air inlet of the first blower device 22 are respectively oriented towards the effect component 3, so that the blowing fan 21, the effect component 3, and the first blower device 22 form an air path. The oil mist generated on the effect component 3 is filtered by the oil removal cover 222 on the first blower device 22, avoiding the escape of the oil mist generated on the effect component 3 in the lamp cavity.

[0025] On the other hand, at the light-emitting lens 4 most affected by the oil mist, the second blower device 23 is reoriented and arranged for oil mist filtration, so that the air blowing towards the light-emitting lens 4 does not contain oil mist, and at the same time, it can also solve the problem that water mist is likely to be generated on the inner surface of the light-emitting lens 4 due to the large temperature difference between the inner and outer surfaces of the light-emitting lens 4 when the waterproof lamp is working.

[0026] In summary, the system simultaneously solves the problems of the escape of the oil mist generated by the oil mist source - effect component 3 in the cavity 100 of the waterproof lamp, and the problems that the light-emitting lens 4 is easily contaminated by the oil mist and water mist is generated due to the temperature difference between the inner and outer surfaces.

[0027] As shown in Figure 2 , the schematic diagram of the first blower device 22 shown in Figure 3, the oil removal cover 222 is a box body including at least three oil removal surfaces 2b, and oil removal cotton 2a is provided on the oil removal surface 2b. Compared with the conventional single-sided or double-sided oil removal device, the oil removal cover 222 has more oil removal surfaces, so the oil removal efficiency is greatly improved.

[0028] Preferably, the box body is a cuboid, and five of its surfaces are oil removal surfaces 2b, and the sixth surface, that is, the bottom surface, is connected to the air outlet of the first blower 221. As can be understood by those skilled in the art, in Figure 2 and 3 , the oil removal cover 222 is provided at the air outlet of the first blower 221, but the position of the oil removal cover 222 is not limited. In the actual solution, the oil removal cover 222 can also be provided at the air inlet of the first blower 221.

[0029] Preferably, the box body includes a main body 2221, a first pressing plate 2222, and the oil removal cotton 2a provided between the two. The first pressing plate 2222 fixes the oil removal cotton 2a on the main body 2221.

[0030] Preferably, ventilation holes 2b1 are provided on each surface of the main body 2221. The air flow containing oil mist inhaled by the first blower 221 passes through the ventilation holes 2b1 and is filtered by the oil removal cotton 2a and then discharged.

[0031] As shown inFigure 4 and 5 As shown in and

[0032] , the second blower device 23 further includes a blower fixing bracket 234 for installing the second blower 231 and a pressing plate 2321 for fixing the second oil removal cotton 232.

[0032] Preferably, the second blower device 23 further includes a wind guiding member 233 connected to the air outlet of the second blower 231. The wind guiding member 233 is used to direct the air sucked by the second blower 231 towards the light emitting lens 4, thereby better solving the problem that the light emitting lens 4 is prone to generate water mist due to the temperature difference between the inner and outer surfaces.

[0033] Preferably, the wind guiding member 233 is welded to the blower fixing bracket 234. This one-piece connection method avoids additionally adding a fixing structure for the wind guiding member 233.

[0034] As shown in the appendix Figure 6 Preferably, the oil mist removal system further includes a wind pressure sensor 235 provided at the air outlet of the first blower 22 or the second blower 23 for monitoring the air volume. The significance of the wind pressure sensor is that it can more intelligently determine when the oil removal cotton needs to be replaced based on the change in the air volume at the air outlet. Because the oil mists generated by different waterproof lamps are different, the traditional method of replacing the oil removal cotton after a certain period of time cannot be quantified, so it is easy to have problems such as premature or late replacement.

[0035] Specifically, before leaving the factory, a test is conducted on the corresponding relationship between the oil mist pollution of the light emitting lens or the focusing and magnifying lens and the air volume at the air outlet of the blower of the waterproof lamp. The wind pressure value corresponding to the air volume of the blower at the pollution critical point is stored as a threshold in the receiving MCU 2351 and can be selectively displayed on the lamp display panel 2352. When the wind pressure value fed back by the wind pressure sensor 235 received by the receiving MCU 2351 in real time is lower than the threshold, it is determined that the working state is normal; when the wind pressure value fed back by the wind pressure sensor 235 received by the receiving MCU in real time is equal to or greater than the threshold, it is determined that the working state is abnormal, and the devices of the oil mist removal system inside this waterproof lamp need to be maintained, such as replacing the oil removal cotton of the first blower device 22 and the second blower device 23 or checking whether the first blower device 22 and the second blower device 23 are abnormal.
