Description

Technical Field

[0001] The utility model relates to the technical field of stage lamps, and more specifically, to a waterproof ventilation module and a stage lamp having the same. Background Art

[0002] Since the power of stage lights is relatively high, in order to dissipate heat, air inlets and exhaust ports are usually opened on the shell that forms the accommodating cavity. Cold air from the outside is sucked in from the air inlet, and after cooling the components in the shell, hot air is discharged from the exhaust port to the outside. However, when stage lights are used outdoors, they may encounter unexpected rainy weather. Rainwater may enter the shell from the air inlet and damage the components inside, such as attaching to the lens to affect the light effect, causing electronic components to short-circuit, or causing metal components to rust. Therefore, existing stage lights cannot meet the requirements of efficient heat dissipation and rainproof. Utility Model Content

[0003] In order to overcome at least one defect of the prior art described above, the utility model provides a waterproof ventilation module, which can realize the functions of waterproofing and ventilation and meet the heat dissipation requirements.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a waterproof ventilation module, including a cavity, the cavity having a first side panel and a second side panel, the first side panel is provided with a first ventilation hole, and a first water retaining panel is provided around the first ventilation hole on the side close to the second side panel, the second side panel is provided with a second ventilation hole, and the second ventilation hole is completely staggered with the first ventilation hole.

[0005] The waterproof ventilation module completely staggers the first ventilation hole and the second ventilation hole on the first side plate and the second side plate which are arranged opposite to each other, so as to prevent raindrops from moving linearly from the second ventilation hole to the first ventilation hole in the process of falling from the air, and a first water retaining panel is arranged around the first ventilation hole on the side of the first side plate close to the second side plate, so that when rainwater entering the cavity flows along the first side plate to the first ventilation hole, it will be blocked by the first water retaining panel, and rainwater is prevented from further entering the first ventilation hole as much as possible. Thus, the function of waterproofing against rain is achieved, and the air circulation between the first ventilation hole and the second ventilation hole is not restricted.

[0006] Furthermore, the minimum distance between the edge of the second vent hole and the edge of the first vent hole is greater than 1 cm. The distance between the second vent hole and the first vent hole is increased to reduce the probability of rainwater moving from the second vent hole into the first vent hole in a curved manner due to air flow disturbance.

[0007] Furthermore, the height of the first water retaining panel protruding from the first side panel is greater than 0.5 cm, so as to ensure that rainwater entering the cavity is not easy to pass over the first water retaining panel when flowing along the first side panel toward the first vent, and is thus blocked outside the first vent by the first water retaining panel.

[0008] Furthermore, a dustproof net is provided on the air duct between the second vent and the first vent, and the dustproof net can block dust in the airflow from the second vent to the first vent, and keep the airflow from the first vent clean enough.

[0009] Furthermore, the second side panel is connected to a carrying platform for carrying the dustproof net near the first side panel, and the second side panel is provided with a mounting opening for disassembling and installing the dustproof net and a cover plate for covering the mounting opening. The dustproof net can be fixed by the carrying platform, and the dustproof net can be conveniently disassembled and installed through the mounting opening, and the mounting opening is then covered by the cover plate to prevent the dustproof net from being exposed.

[0010] Furthermore, a water retaining ring is arranged outside the first water retaining panel, and the water retaining ring can block rainwater entering the cavity when it moves along the first water retaining panel away from the first side panel, thereby preventing rainwater from entering the inside of the first water retaining panel.

[0011] Further, a plurality of the first ventilation holes are arranged on the first side plate, the number of the first water retaining panels is one, and one first water retaining panel surrounds all the first ventilation holes, or the number of the first ventilation holes and the first water retaining panels is multiple, and each of the first water retaining panels surrounds at least one first ventilation hole, as long as all the first ventilation holes are surrounded by the first water retaining panels.

[0012] Further, a second water retaining panel is provided on the second side panel, and the second water retaining panel surrounds the first water retaining panel. The second water retaining panel on the second side panel surrounds the first water retaining panel, and can prevent rainwater entering the cavity from flowing along the second side panel to the opposite side of the first vent and then entering the first vent.

[0013] Furthermore, the second water retaining panel and the first water retaining panel are staggered in the height direction of both sides, so as to ensure that a small amount of raindrops bypassing the second water retaining panel will not easily enter the first ventilation hole in the first water retaining panel.

[0014] Furthermore, the staggered height of the second water retaining panel and the first water retaining panel in the height direction is greater than 0.1 cm, which fully ensures that a small amount of raindrops bypassing the second water retaining panel are difficult to enter the first ventilation hole in the first water retaining panel.

[0015] Furthermore, a water retaining ring is arranged outside the first water retaining panel, and the outer edge of the water retaining ring is located outside the second water retaining panel, so that rainwater blocked by the water retaining ring will not enter the inner side of the second water retaining panel when falling from the outer edge of the water retaining ring, thereby effectively preventing the rainwater from finally entering the first ventilation hole.

[0016] Furthermore, the number of the second water retaining panels is one, surrounding all the first water retaining panels. In this way, when the first side panel and the second side panel are arranged opposite to each other, the second water retaining panels are not likely to interfere with the first water retaining panels, and installation and alignment are facilitated.

[0017] Furthermore, the second side plate is detachably fixed to the first side plate, so as to facilitate assembly to form the cavity and to set the first water retaining wall.

[0018] The utility model also provides a stage lamp, comprising any of the aforementioned waterproof ventilation modules, wherein the lamp head, arm or housing cavity of the stage lamp is connected to the outside world through the waterproof ventilation module. By using the waterproof ventilation module, the housing cavity can be connected to the outside world for heat dissipation, and rainwater from the outside can be effectively prevented from entering the housing cavity.

[0019] Furthermore, the waterproof ventilation module is provided at both the air inlet and the air outlet of the accommodating cavity so that rainwater cannot enter the accommodating cavity from either the air inlet or the air outlet.

[0020] Furthermore, the lamp head, arm or accommodating cavity in the case of the stage lamp are interconnected. In this way, the waterproof ventilation module can be arranged at any reasonable position of the stage lamp, so that the waterproof ventilation of the whole lamp can be realized.

[0021] Furthermore, the first side plate is a part of the side wall of the accommodating cavity, and the second side plate is located outside the accommodating cavity. Directly using a part of the existing side wall of the accommodating cavity as the first side plate simplifies the overall structure of the waterproof ventilation module.

[0022] Furthermore, the first side plate is a supporting side plate for the lamp head to be pivotally connected to the arm, and the second side plate is a side cover provided on the outside of the supporting side plate. The waterproof ventilation module is formed by using a part of the existing supporting side plate and a part of the side cover, without adding additional components, and the space utilization rate is higher.

[0023] Furthermore, the first side plate is a mounting plate for the light-emitting lens of the lamp holder, that is, the lamp holder takes in and out wind from its light-emitting position. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The drawings are only for illustrative purposes and cannot be construed as limiting the present invention. To better illustrate the present embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are only for illustrative purposes and cannot be construed as limiting the present invention.

[0034] like Figure 1 to Figure 2The utility model provides a waterproof ventilation module 100, including a cavity 110, wherein the cavity 110 has a first side plate 120 and a second side plate 130, wherein the first side plate 120 is provided with a first ventilation hole 121, and a first water retaining plate 122 is provided around the first ventilation hole 121 on a side thereof close to the second side plate 130, and the second ventilation hole 131 is provided on the second side plate 130, and the second ventilation hole 131 is completely staggered with the first ventilation hole 121.

[0035] When in use, the second ventilation hole 131 is generally connected to the outside, and the first ventilation hole 121 is connected to the accommodating cavity that needs to be protected from air intake and waterproof. The waterproof ventilation module 100 completely staggers the first ventilation hole 121 and the second ventilation hole 131 on the first side plate 120 and the second side plate 130 that are relatively arranged, so as to prevent raindrops from moving linearly from the second ventilation hole 131 to the first ventilation hole 121 during falling from the air, and a first water retaining panel 122 is arranged around the first ventilation hole 121 on the side of the first side plate 120 close to the second side plate 130, so that when rainwater entering the cavity 110 flows along the first side plate 120 to the first ventilation hole 121, it will be blocked by the first water retaining panel 122, and rainwater is prevented from further entering the first ventilation hole 121 as much as possible. Thus, the function of waterproofing against rain is achieved, and the air circulation between the first ventilation hole 121 and the second ventilation hole 131 is not restricted.

[0036] It should be noted that the second ventilation hole 131 is completely staggered with the first ventilation hole 121 , which means that the projection of the second ventilation hole 131 on the first side plate 120 in a direction perpendicular to the first side plate 120 is located outside the first ventilation hole 121 .

[0037] In this embodiment, the first side plate 120 and the second side plate 130 are arranged opposite to each other. In other embodiments, the two do not have to be completely opposite to each other.

[0038] In this embodiment, the cavity 110 is completely sealed, and in other embodiments, it may also have a gap communicating with the outside.

[0039] In this embodiment, the height direction of the first water retaining panel 122 is perpendicular to the first side panel 120 . In other embodiments, the height direction of the first water retaining panel 122 may not be completely perpendicular to the first side panel 120 .

[0040] In this embodiment, the first vent is circular, and the first water retaining panel 122 is cylindrical.

[0041] In a preferred embodiment of the present invention, the minimum distance between the edge of the second ventilation hole 131 and the edge of the first ventilation hole 121 is greater than 1 cm. The distance between the second ventilation hole 131 and the first ventilation hole 121 is increased to reduce the probability of rainwater moving from the second ventilation hole 131 into the first ventilation hole 121 due to air flow disturbance.

[0042] In a preferred embodiment of the utility model, the height of the first water retaining panel 122 protruding from the first side panel 120 is greater than 0.5 cm, so as to ensure that rainwater entering the cavity 110 is not easy to pass over the first water retaining panel 122 when flowing along the first side panel 120 toward the first ventilation hole 121, and is thus blocked outside the first ventilation hole 121 by the first water retaining panel 122.

[0043] Preferably, the height of the first water retaining panel 122 protruding from the first side panel 120 is less than 5 cm, so as to avoid that the distance between the first side panel 120 and the second side panel 130 is too large, which would cause the overall volume of the waterproof ventilation module 100 to be too large.

[0044] In a preferred embodiment of the utility model, a dustproof net 140 is provided on the air duct between the second vent 131 and the first vent 121. The dustproof net 140 can block dust in the airflow from the second vent 131 to the first vent 121, and keep the airflow from the first vent 121 clean enough.

[0045] In a preferred embodiment of the present invention, the second side plate 130 is connected to a carrying platform 133 for carrying the dustproof net 140 near the first side plate 120, and the second side plate 130 is provided with a mounting opening 134 for disassembling and installing the dustproof net 140 and a cover plate 135 (such as a cover plate 135 for covering the mounting opening 134). Figure 2 The dustproof net 140 can be fixed by the support platform 133, and the dustproof net 140 can be conveniently disassembled and assembled through the mounting opening 134, and the mounting opening 134 is covered by the cover plate 135 to prevent the dustproof net 140 from being exposed.

[0046] In this embodiment, the supporting platform 133 and the second side panel 130 are integrally formed, including a supporting plate 1331 and a connecting plate 1332 connecting the supporting plate 1331 and the first side panel 120, and the connecting plate 1332 is provided with a plurality of air holes 1333 allowing air flow to flow between the first ventilation hole 121 and the second ventilation hole 131.

[0047] The cover plate 135 is provided with an elastic locking tongue 1351 for locking with the second side plate 130 .

[0048] In a preferred embodiment of the utility model, a water retaining ring 123 is disposed outside the first water retaining panel 122. The water retaining ring 123 can block rainwater entering the cavity 110 when it moves along the first water retaining panel 122 away from the first side panel 120, thereby preventing rainwater from entering the first water retaining panel 122.

[0049] In this embodiment, the water retaining ring 123 is made of soft rubber material, is sleeved on the outer side of the first water retaining panel 122, and is fixed by its own elasticity.

[0050] Optionally, the dustproof net 140 can be located at any position in the air duct, preferably at a position close to the second ventilation hole 131, so that the dustproof net 140 can not only break up the rainwater entering the second ventilation hole 131 to prevent it from flowing in strands, but also play a certain role in preventing rainwater, and ensure that the airflow entering the cavity 110 is clean from the source.

[0051] In a preferred embodiment of the present invention, a plurality of first ventilation holes 121 are provided on the first side plate 120, and the number of the first water retaining panel 122 is one, and one first water retaining panel 122 surrounds all the first ventilation holes 121 (such as Figure 1 ), or the number of the first ventilation holes 121 and the first water retaining panels 122 is multiple, and each of the first water retaining panels 122 surrounds at least one of the first ventilation holes 121 (such as Figure 2 ), as long as all of the first ventilation holes 121 are surrounded by the first water retaining panel 122.

[0052] Preferably, each of the first ventilation holes 121 is correspondingly provided with a first water retaining panel 122 .

[0053] In a preferred embodiment of the utility model, a second water retaining panel 132 is provided on the second side panel 130, and the second water retaining panel 132 surrounds the first water retaining panel 122. The second water retaining panel 132 on the second side panel 130 surrounds the first water retaining panel 122, which can prevent rainwater entering the cavity 110 from flowing along the second side panel 130 to the opposite side of the first ventilation hole 121 and then entering the first ventilation hole 121.

[0054] Preferably, the height of the second water retaining panel 132 is greater than or equal to 0.5 cm.

[0055] In a preferred embodiment of the utility model, the second water retaining board 132 and the first water retaining board 122 are staggered in the height direction of both sides, so as to ensure that a small amount of raindrops bypassing the second water retaining board 132 will not easily enter the first ventilation hole 121 in the first water retaining board 122 .

[0056] In a preferred embodiment of the utility model, the staggered height of the second water retaining board 132 and the first water retaining board 122 in the height direction is greater than 0.1 cm, which fully ensures that a small amount of raindrops bypassing the second water retaining board 132 are difficult to enter the first ventilation hole 121 in the first water retaining board 122.

[0057] In a preferred embodiment of the utility model, a water retaining ring 123 is arranged outside the first water retaining panel 122, and the outer edge of the water retaining ring 123 is located outside the second water retaining panel 132. In this way, it can be ensured that rainwater blocked by the water retaining ring 123 will not enter the inner side of the second water retaining panel 132 when falling from the outer edge of the water retaining ring 123, thereby effectively preventing the rainwater from finally entering the first ventilation hole 121.

[0058] When a plurality of the first ventilation holes 121 and a plurality of the first water retaining panels 122 are provided on the first side plate 120 , the water retaining rings 123 outside all the first water retaining panels 122 may be connected as a whole.

[0059] Optionally, regardless of the number of the first water retaining panels 122, the second water retaining panels 132 may be one, surrounding all the first water retaining panels 122 (eg, Figure 1 ), or multiple, each of which surrounds one or more of the first water retaining panels 122 (such as Figure 2 ).

[0060] In a preferred embodiment of the utility model, the number of the second water retaining panel 132 is one, surrounding all the first water retaining panels 122. In this way, when the first side panel 120 and the second side panel 130 are arranged opposite to each other, the second water retaining panel 132 and the first water retaining panel 122 are not likely to interfere with each other, and installation and alignment are facilitated.

[0061] Preferably, the cavity 110 is formed by the first side plate 120 and the second side plate 130 being buckled together.

[0062] In a preferred embodiment of the present invention, the second side plate 130 is detachably fixed to the first side plate 120 , so as to facilitate assembly to form the cavity 110 and to set the first water retaining wall 122 .

[0063] like Figures 3 to 7The utility model also provides a stage light, comprising any of the aforementioned waterproof ventilation modules 100, wherein the lamp head 200, the arm 300 or the accommodating cavity 500 in the chassis 400 of the stage light is connected to the outside through the waterproof ventilation module 100. By using the waterproof ventilation module 100, the accommodating cavity 500 can be connected to the outside for heat dissipation, and rainwater from the outside can be effectively prevented from entering the accommodating cavity 500.

[0064] The stage light may include the lamp head 200 alone, or include the lamp head 200 and the arm 300 supporting the rotation of the lamp head 200, or include the lamp head 200, the arm 300 supporting the rotation of the lamp head 200, and the chassis 400 supporting the rotation of the arm 300. The accommodating cavity 500 of the lamp head 200 is provided with a light source and an effect component that intercepts the light emitted by the light source and produces light effects. The effect component may be one or more of a CMY group module, a cutter module 260, a fire disk module 270, a pattern disk module, or a color plate module. The accommodating cavity 500 in the chassis 400 is provided with a switching power supply.

[0065] In a preferred embodiment of the utility model, the air inlet and the air outlet of the accommodating cavity 500 are both provided with the waterproof ventilation module 100 so that rainwater cannot enter the accommodating cavity 500 from either the air inlet or the air outlet.

[0066] When the waterproof ventilation module 100 is set at the air inlet of the accommodating cavity 500, the external gas flows from the second ventilation hole 131 to the first ventilation hole 121; when the waterproof ventilation module 100 is set at the air outlet of the accommodating cavity 500, the external gas flows from the first ventilation hole 121 to the second ventilation hole 131.

[0067] In a preferred embodiment of the utility model, the lamp head 200, the arm 300 or the accommodating cavity 500 in the chassis 400 of the stage lamp are interconnected. In this way, the waterproof ventilation module 100 can be set at any reasonable position with redundant space in the stage lamp, so that the waterproof ventilation of the whole lamp can be achieved.

[0068] In a preferred embodiment of the present invention, the first side plate 120 is a part of the side wall of the accommodating cavity 500, and the second side plate 130 is located outside the accommodating cavity 500. Directly using a part of the existing side wall of the accommodating cavity 500 as the first side plate 120 simplifies the overall structure of the waterproof ventilation module 100.

[0069] like Figures 4 to 5In a preferred embodiment of the utility model, the first side plate 120 is a supporting side plate 210 for the lamp head 200 to be pivotally connected to the arm 300, and the second side plate 130 is a side cover 220 provided on the outside of the supporting side plate 210. The waterproof ventilation module 100 is formed by using a part of the existing supporting side plate 210 and a part of the side cover 220, without adding additional components, and the space utilization rate is higher.

[0070] Preferably, the first ventilation hole 121 is disposed close to the light output lens 240 .

[0071] In a preferred embodiment of the utility model, the first side plate 120 is a mounting plate 230 of the light-emitting lens 240 of the lamp head 200. That is, the lamp head 200 is blown in and out from its light-emitting position. In this case, the second side plate 130 can be a lens cover 250 covering the mounting plate 230, or a side cover 220 covering the outer side of the supporting side plate 210 of the lamp head 200 for pivoting with the arm 300.

[0072] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
