Description

Technical Field

[0001] The utility model relates to the field of waterproof stage / landscape lamps, in particular to the field of oil mist removal devices for waterproof lamps. Background Art

[0002] The waterproof lamps in the stage lighting industry have a high temperature inside the lamps due to their sealed structure when they are working, which will cause the lubricating oil and paint coatings on various components inside the lamps to vaporize. The oil mist gas generated in the closed lamp cavity will seriously contaminate the lens and other components of the lamps over time, causing the brightness and clarity of the lamps to decrease with the increase of usage time. Currently, the industry only conducts regular manual cleaning of the interior of the lamps, which increases maintenance costs.

[0003] At the same time, even if oil removal materials are added to the air inlet or outlet of the fan, there is only one oil removal surface, the oil removal efficiency is low, and the oil absorption cotton needs to be replaced in a short time, and the maintenance frequency is high. Summary of the invention

[0004] The purpose of the present invention is to provide a de-oiling device for waterproof lamps to solve the above problems. The technical solution of the present invention is as follows:

[0005] A de-oiling mist device for a waterproof lamp is arranged in the cavity of the waterproof lamp, comprising a fan and an oil removal hood connected to the air inlet or outlet of the fan, wherein the oil removal hood comprises at least three oil removal surfaces in different directions, and each of the oil removal surfaces is correspondingly provided with an adapted oil absorbing cotton.

[0006] Furthermore, the air inlet and the air outlet of the fan are arranged opposite to each other.

[0007] Furthermore, the air inlet direction and the air outlet direction of the fan are parallel.

[0008] Furthermore, the fan is a blower.

[0009] Furthermore, the oil removal cover is a box body.

[0010] Furthermore, one of the surfaces of the box body is connected to the air inlet or outlet of the fan.

[0011] Furthermore, the other surfaces of the box body are all oil-removing surfaces, and the oil-removing surfaces are provided with a second air outlet and oil-absorbing cotton adapted to the second air outlet.

[0012] Furthermore, the box body includes a main body, an oil-absorbing cotton pressing plate and oil-absorbing cotton located between the main body and the oil-absorbing cotton pressing plate, and air outlets 2 are provided on multiple surfaces of the main body.

[0013] Furthermore, the oil-absorbing cotton is adapted to the second air outlet.

[0014] Furthermore, the oil-absorbing cotton is honeycomb active oil-absorbing cotton.

[0015] Compared with the traditional technical solution, the advantages of this technical solution are: an oil removal hood is set on the air inlet or outlet of the fan. Since the oil removal hood includes at least three oil removal surfaces in different directions, when filtering the oil mist gas inside the lamp, it is a three-dimensional oil removal mode, rather than a conventional single-sided oil removal mode; the oil mist removal efficiency of the three-dimensional oil removal mode is several times that of the conventional single-sided oil removal mode, and the replacement frequency of the oil-absorbing cotton is much lower than that of the conventional single-sided oil removal surface design; in addition, based on actual experience, when the amount of oil mist generated in lamps of different volumes over a period of time is different, the size of the oil removal hood box can be changed to achieve optimization of the oil removal efficiency and the space occupied by the oil removal hood.

[0027] Embodiment 1

[0028] As attached Figure 1 As shown in FIG2 , an oil mist removal device for a waterproof lamp is arranged in the cavity of the waterproof lamp, including a fan 1 and an oil mist removal cover 2 connected to the air outlet 1b of the fan 1. The oil mist removal cover 2 includes at least three oil mist removal surfaces 2b in different directions, and each oil mist removal surface 2b is correspondingly provided with an adapted oil absorbent cotton 23.

[0029] In this embodiment, the oil removal cover 2 is a rectangular box body; each surface of the rectangular box body is provided with an opening, including two air outlets (2b1, 2b2, 2b3, 2b4, 2b5) and two air inlets (2b6). The two air inlets (2b6) on the bottom surface are connected to the air outlet 1b of the fan 1.

[0030] The air flow in the lamp cavity is sucked in from the air inlet 1a by the fan 1, enters the degreasing cover 2 through the air outlet 1b and the second air inlet (2b6), and then is discharged from the second air outlet (2b1, 2b2, 2b3, 2b4, 2b5) of the degreasing cover 2. Because each degreasing surface 2b is provided with a corresponding oil-absorbing cotton (231, 232, 233, 234, 235), during the whole process, the oil mist contained in the air flow in the lamp cavity will be adsorbed on the oil-absorbing cotton (231, 232, 233, 234, 235) on each surface of the degreasing cover 2, thereby achieving the effect of purifying the oil mist in the air inside the waterproof lamp, so that the oil mist will no longer adhere to the optical lens due to the circulation inside the lamp and affect the incident / exit of light.

[0031] As one implementation manner, the fan 1 is a blower, and its air inlet is 1a and its air outlet is 1b.

[0032] In this embodiment, the box body includes a main body 21, an oil-absorbing cotton pressing plate (221, 222, 223, 224, 225) and oil-absorbing cotton (231, 232, 233, 234, 235) located therebetween. The main body 21 includes an air inlet 2 (2b6) on the bottom surface and air outlets 2 (2b1, 2b2, 2b3, 2b4, 2b5) on other surfaces. The size of the oil-absorbing cotton (221, 222, 223, 224, 225) is adapted to the air outlet 2 (2b1, 2b2, 2b3, 2b4, 2b5), and the oil-absorbing cotton (221, 222, 223, 224, 225) is used to filter oil mist. Therefore, the oil removal cover 2 has five surfaces as oil removal surfaces 2b, which can be used to filter the air containing oil mist inside the lamp sucked in by the fan 1. This embodiment belongs to a three-dimensional oil removal mode, and the oil removal efficiency is much higher than the traditional single-sided oil removal mode. At the same time, the replacement frequency of the oil-absorbing cotton 23 is also much lower than the traditional single-sided oil removal mode.

[0033] In addition, the oil-absorbing cotton 23 is honeycomb active oil-absorbing cotton, and this type of oil-absorbing cotton has a relatively better oil-absorbing effect.

[0034] Embodiment 2

[0035] As attached Figure 3 As shown in Figure 4, an oil mist removal device for a waterproof lamp is arranged in the cavity of the waterproof lamp, including a fan 1 and an oil removal cover 2 connected to the air inlet 1a of the fan 1. The oil removal cover 2 includes at least three oil removal surfaces 2b in different directions, and each oil removal surface 2b is correspondingly provided with an adapted oil absorbent cotton 23.

[0036] In this embodiment, the oil removal cover 2 is a square box body; each surface of the square box body is provided with an opening, including five air inlets 2b1 and one air outlet 2 (2b6). The air outlet 2 (2b6) is connected to the air inlet 1a of the fan 1.

[0037] Under the negative pressure of the air inlet 1a of the fan 1, the air flow in the lamp cavity is sucked into the de-oiling hood 2 from the air inlet 2b1 of the de-oiling hood 2, enters the fan 1 through the air outlet 2 (2b6), and finally is discharged through the air outlet 1b of the fan 1. Because each de-oiling surface 2b is provided with a corresponding oil-absorbing cotton 23, during the whole process, the oil mist contained in the air flow in the lamp cavity will be adsorbed on the oil-absorbing cotton 23 on each surface of the de-oiling hood 2, thereby achieving the effect of purifying the oil mist in the air inside the waterproof lamp, so that the oil mist will no longer adhere to the optical lens due to the circulation inside the lamp and affect the incident / exit of light.

[0038] As one implementation manner, the fan 1 is a blower, and its air inlet is 1a and its air outlet is 1b.

[0039] In this embodiment, the box body includes a main body 21, an oil-absorbing cotton pressing plate 221 and an oil-absorbing cotton 23 located therebetween. The main body 21 includes an air outlet 2 (2b6) that is in close contact with the fan 1 and an air inlet 2b1 on the other surface. The size of the oil-absorbing cotton 23 is adapted to the air inlet 2b1, and the oil-absorbing cotton 23 is used to filter oil mist. Therefore, the oil removal hood 2 has five surfaces as oil removal surfaces 2b, which can be used to filter the air containing oil mist inside the lamp that is sucked in from outside the oil removal hood 2. This embodiment belongs to a three-dimensional oil removal mode, and the oil removal efficiency is much higher than the traditional single-sided oil removal mode. At the same time, the replacement frequency of the oil-absorbing cotton 23 is also much lower than the traditional single-sided oil removal mode.

[0040] In addition, the oil-absorbing cotton 23 is honeycomb active oil-absorbing cotton, and this type of oil-absorbing cotton has a relatively better oil-absorbing effect.

[0041] Embodiment 3

[0042] As attached Figure 5 As shown in Figure 6, an oil mist removal device for a waterproof lamp is arranged in the cavity of the waterproof lamp, including a fan 1 and an oil removal cover 2 connected to the air inlet 1a of the fan 1. The oil removal cover 2 includes at least three oil removal surfaces 2b in different directions, and each oil removal surface 2b is correspondingly provided with an adapted oil absorbent cotton 23.

[0043] In this embodiment, the oil removal cover 2 is a square box body; each surface of the square box body is provided with an opening, including five air inlets 2b6 and one air outlet 2 (2b1). The air outlet 2 (2b1) is connected to the air inlet 1a of the fan 1.

[0044] Under the negative pressure of the air inlet 1a of the fan 1, the air flow in the lamp cavity is sucked into the de-oiling hood 2 from the air inlet 2b6 of the de-oiling hood 2, enters the fan 1 through the air outlet 2 (2b1), and finally discharged through the air outlet 1b of the fan 1. Because each de-oiling surface 2b is provided with a corresponding oil-absorbing cotton 23, during the whole process, the oil mist contained in the air flow in the lamp cavity will be adsorbed on the oil-absorbing cotton 23 on each surface of the de-oiling hood 2, thereby achieving the effect of purifying the oil mist in the air inside the waterproof lamp, so that the oil mist will no longer adhere to the optical lens due to the circulation inside the lamp and affect the incident / exit of light.

[0045] As one embodiment, the fan 1 is a rectangular DC fan, with an air inlet 1a and an air outlet 1b. The air inlet 1a and the air outlet 1b of the fan are arranged opposite to each other, and the air inlet direction and the air outlet direction of the fan 1 are parallel.

[0046] In this embodiment, the box body includes a main body 21, an oil-absorbing cotton pressing plate 221 and an oil-absorbing cotton 23 located therebetween. The main body 21 includes an air outlet 2 (2b1) that is in close contact with the fan 1 and an air inlet 2b6 on the other surface. The size of the oil-absorbing cotton 23 is adapted to the air inlet 2b6, and the oil-absorbing cotton 23 is used to filter oil mist. Therefore, the oil removal hood 2 has five surfaces as oil removal surfaces 2b, which can be used to filter the air containing oil mist inside the lamp that is sucked in from outside the oil removal hood 2. This embodiment belongs to a three-dimensional oil removal mode, and the oil removal efficiency is much higher than the traditional single-sided oil removal mode. At the same time, the replacement frequency of the oil-absorbing cotton 23 is also much lower than the traditional single-sided oil removal mode.

[0047] In addition, the oil-absorbing cotton 23 is honeycomb active oil-absorbing cotton, and this type of oil-absorbing cotton has a relatively better oil-absorbing effect.

[0048] Embodiment 4:

[0049] As attached Figure 7 As shown, it can be understood by technicians in this industry that the only difference between this embodiment and the third embodiment is that the installation position of the fan 1 is changed from the left side of the oil-proof cover 2 to the right side, and each oil removal surface 2b of the oil removal cover 2 is the air outlet surface.
