Description

Technical Field

[0001] This invention relates to a fan device, and more particularly to a fan device suitable for use on stage in conjunction with equipment such as smoke machines and bubble machines. Background Technology

[0002] Special effects equipment such as smoke machines, bubble machines, and snow machines may be installed on known performance stages and entertainment venues (such as amusement parks and celebration venues). The smoke, bubbles, and snow generated by these special effects equipment need to be pushed by airflow to control their diffusion direction and distance. Therefore, additional special effects fan devices are also configured on the performance stage to generate appropriate airflow to help the smoke, bubbles, or snow to be blown to a predetermined position or to diffuse faster.

[0003] The performance stages and entertainment venues are often outdoors and may be exposed to rain. The electronic components inside the fan device may short-circuit when exposed to water. Therefore, the fan devices used in performance stages and entertainment venues need to be waterproof. Summary of the Invention

[0004] Therefore, the object of the present invention is to provide a fan device.

[0005] This invention provides a fan device, including an assembly frame connected to a fan motor that drives a fan blade to rotate. The fan device further includes a waterproof electronic control module and a waterproof operation module, both connected to the assembly frame. The waterproof electronic control module includes a first waterproof outer casing and a main control circuit housed within the first waterproof outer casing. The waterproof operation module further includes a second waterproof outer casing, an operation interface connected to the second waterproof outer casing, and an operation interface control circuit. The operation interface is exposed on the outside of the second waterproof outer casing, and the operation interface control circuit is sealed within the second waterproof outer casing and electrically connected to the main control circuit.

[0006] The waterproof operating module, the waterproof electrical control module, and the fan motor are all waterproof, so the fan device can be used outdoors without worrying about getting wet in the rain.

[0007] In one embodiment, the first waterproof outer box further includes a box body and a cover body joined together. The box body includes an upwardly facing mating surface and an accommodating space recessed from the mating surface. The box body further includes a waterproof enclosure protruding from the mating surface and surrounding the accommodating space. The cover body includes a groove corresponding to the waterproof enclosure, and a sealing ring is disposed in the groove. The main control circuit is fixed within the accommodating space. The cover body is joined to the mating surface and seals the accommodating space. The waterproof enclosure abuts against the sealing ring.

[0008] The waterproof enclosure of the housing of the waterproof electrical control module protrudes from the joint surface and surrounds the outer perimeter of the accommodating space, so water is not easily seeped into the accommodating space from the gap between the cover and the housing. As a result, the first waterproof outer box provides a good waterproof effect, and the main control circuit is not easily damaged by water.

[0009] In one embodiment, the fan device further includes:

The operating interface control circuit is separated from the lower cover. The inner retaining wall presses against the waterproof ring.

[0011] The control circuit of the waterproof operation module is fixed inside the upper cover and separated from the lower cover. The suspended design of the control circuit reduces the chance of it coming into contact with water. The downward-protruding inner baffle in the upper cover makes it difficult for water from outside the second waterproof outer box to enter the internal space, further reducing the likelihood of the control circuit coming into contact with water, thus providing excellent waterproofing.

[0012] In one embodiment, the box body of the first waterproof outer box further includes an end face and an inner recessed face, the inner recessed face being located between the end face and the accommodating space, a first waterproof sleeve being fixedly disposed on the inner recessed face, the end of the first waterproof sleeve being located between the inner recessed face and the end face, the upper cover of the second waterproof outer box includes a tail end and an inner sidewall, the inner sidewall being located between the tail end and the internal space, a second waterproof sleeve being fixedly disposed on the inner sidewall, the end of the second waterproof sleeve being located between the tail end and the inner sidewall, the operation interface control circuit and the main control circuit being electrically connected through a control line, the control line being tightly connected to the first waterproof sleeve and the second waterproof sleeve.

[0022] The waterproof electronic control module is adjacent to the installation space and located directly behind the fan blades. With the help of a plurality of heat dissipation fins, when the fan blades are running, the airflow can pass through the plurality of heat dissipation fins of the waterproof electronic control module, so that the temperature of the main control circuit can be well controlled.

[0023] In one embodiment, the fan device further includes:

[0024] A shaft cover includes a sealing oil chamber. The fan motor includes a front end face and a rotating shaft protruding from the front end face. The shaft cover abuts against the front end face. The rotating shaft extends through the sealing oil chamber and is filled with a highly viscous sealing oil inside and outside the rotating shaft.

[0025] The fan motor can be fitted with a high-viscosity sealing oil and an external seal via the shaft cover, which effectively prevents water from entering the fan motor through the gap between the front end face and the shaft.

The first portion 30 also includes a fitting groove 38 extending from the second end 34 to the first end 32 and spaced apart from the first end 32. The fitting groove 38 may, but is not limited to, extend radially through the annular wall of the first portion 30 to form two open openings. The fitting groove 38 is adjacent to the mounting space 36. The first portion 30 also includes a receiving opening 39 extending radially from its annular wall and two assembly holes 40. The receiving opening 39 is spaced apart from the fitting groove 38 in a circumferential direction around a central axis of the first portion 30.

[0043] The second part 42 includes a chamber 44, and the second part 42 further includes a plurality of mounting holes 46 formed on two sides, and the second part 42 also includes a through hole 45 formed on the upper side, the through hole 45 communicating with the chamber 44.

Each of the third assembly ends 25 is spaced apart radially from the surrounding wall of the first part 30.

[0045] In essence, the connection between the first part 30 and the second part 42 can be, but is not limited to, using welding, for example, welding between the periphery of the fitting groove 38 and the second part 42. The connection between the bracket 20 and the assembly frame 28 can be, but is not limited to, using welding for fixing, for example, welding each of the first assembly ends 22 to the periphery of each of the assembly holes 46, and welding each of the second assembly ends 24 to the periphery of each of the mounting holes 46.

[0046] The fan device 10 further includes an assembly frame 62 and a fan motor 48. The assembly frame 62 includes a first part 62A and a second part 62B. The first part 62A includes an assembly surface 63 and a plurality of lugs 64 extending vertically from the outer periphery of the assembly surface 63.

[0047] The fan motor 48 includes a front end face 48A and a rear end face 48B, and the fan motor 48 further includes a rotating shaft 48D protruding from the front end face 48.

[0048] The second part 62B of the assembly frame 62 is attached to the front end face 48A of the fan motor 48. A shaft cover 53 is provided between the second part 62B and the front end face 48A. The shaft cover 53 may be, but is not limited to, being made of Teflon material with self-lubricating properties. (See reference...) Figure 4 , Figure 9 As shown, the shaft cover 53 includes an annular groove 53B recessed from one end abutting the front end face 48A and a sealing oil chamber 53A. The sealing oil chamber 53A is located inside the annular groove 53B. The rotating shaft 48D passes through the sealing oil chamber 53A through the shaft cover 53 and the second part 62B. The sealing oil chamber 53A and the outer side of the rotating shaft 48D are filled with highly viscous sealing oil, which can prevent water from entering the fan motor 48 from the gap between the rotating shaft 48D and the front end face 48A.

[0049] An outer sealing ring 53C is placed in the annular groove 53B of the shaft cover 53. The outer sealing ring 53C also abuts against the front end face 48A of the fan motor 48, so that water cannot seep in from the gap between the shaft cover 53 and the front end face 48A.

[0050] Each of the lugs 64 of the first portion 62A engages with the first end 32 of the first portion 30. The fan motor 48 is fixed on the assembly surface 63 of the first portion 62A, such that the fan motor 48 is accommodated within the mounting space 36 and spaced apart from the second portion 42, and the fan motor 48 is also spaced apart from the inner peripheral surface of the first portion 30 (e.g., Figure 8 As shown), the fan motor 48 includes a shaft that is rotatably coupled with a fan blade 58.

[0051] The fan assembly 10 further includes a rear cover 66 through which airflow can pass and a front cover 70 through which airflow can pass. The rear cover 66 includes a plurality of first connecting portions 68 arranged in a ring and a plurality of second connecting portions 69 arranged in a ring. The rear cover 66 is housed within the bracket 20, and the plurality of first connecting portions 68 are fixedly connected to the plurality of third assembly ends 25 (e.g., ...). Figure 10 As shown), the first end 32 of the first portion 30 is fitted inside the rear cover 66, and the front cover 70 is fixedly connected to a plurality of the second connecting portions 69 (as shown). Figure 9As shown, the fan blade 58 is positioned axially between the front cover 70 and the rear cover 66 along the shaft of the fan motor 48. When the fan blade 58 rotates, airflow is drawn in from the rear cover 66 and blown out from the front cover 70.

[0052] The fan device 10 also includes a waterproof electronic control module 74, which includes a first waterproof outer box 76 and a main control circuit 94 housed within the first waterproof outer box 76. The first waterproof outer box 76 includes a box body 78 and a cover 88.

The box body 78 includes a mating surface 80 and an accommodating space 84 recessed from the mating surface 80. The box body 78 further includes a waterproof enclosure 82 protruding from the mating surface 80 and surrounding the accommodating space 84. The box body 78 further includes a plurality of heat dissipation fins 78 protruding from the outer surface.

[0053] The housing 78 further includes an end face 81 located on the same side and two recessed faces 83 spaced apart from the end face 81. The two recessed faces 83 are spaced apart from each other and are located between the end face 81 and the accommodating space 84. That is, each recessed face 83 is formed as the sidewall of a groove recessed relative to the end face 81. A plurality of first waterproof sleeves 86 for providing waterproof grounding for electrical wires are fixed on each recessed face 83. The ends of each first waterproof sleeve 86 are located between the recessed face 83 and the end face 81, so that each first waterproof sleeve 86 can be covered by the mating surface 80. Figure 2 In the embodiment shown, the left inner surface 83 is provided with one first waterproof sleeve 86, and the right inner surface 83 is provided with three first waterproof sleeves 86.

[0054] The cover 88 is recessed on one lower surface of the mating surface 80 to form a groove 90 that conforms to the shape of the waterproof wall 82. A sealing ring 92 is fitted into the groove 90. The cover 88 is abutted against the mating surface 80 of the box 78. The waterproof wall 82 fits into the groove 90 and presses against the sealing ring 92, thus sealing the accommodating space 84 waterproofly. The main control circuit 94 is housed in the accommodating space 84 and is thermally connected to the box 78. A plurality of waterproof electrical connectors 95 are further waterproofly fixed on the box 78, and each waterproof electrical connector 95 is electrically connected to the main control circuit 94 from inside the accommodating space 84.

[0055] The waterproof electrical control module 74 is housed within the chamber 44 of the second portion 42 of the assembly frame 28. The second portion 42 can be combined with an end cap 72 to confine the waterproof electrical control module 74 within the chamber 44. A plurality of first waterproof sleeves 86 face the fan motor 48, and a plurality of waterproof electrical connectors 95 face outward. The main control circuit 94 is electrically connected to the fan motor 48 via at least one motor control line 49. The motor control line 49 is sealed to at least one of the first waterproof sleeves 86 and enters the housing space 84 and is electrically connected to the main control circuit 94, thus preventing water from entering the housing space 84 along the motor control line 49.

[0056] The fan device 10 further includes a waterproof operating module 97, which includes a second waterproof outer box 98. The second waterproof outer box 98 includes an upper cover 111 and a lower cover 135 located below the upper cover 111. The upper cover 111 includes a mating surface 113 facing the lower cover 135. The lower cover 135 further includes an internal space 117 extending from the mating surface 113. The internal space 117 includes an inner end face 119 located at the upper end. The mating surface 113 protrudes to extend an inner baffle 115, which surrounds the outer perimeter of the internal space 117. The upper cover 111 also includes a component extending from the inner end face 119 to... An external opening 133 is provided, and a plurality of joint portions 131 extend protrudingly from the inner end face 119 and around the outer periphery of the opening 133. The lower cover 135 also includes an inner sidewall 116 adjacent to the internal space 117 and including a circular hole, and a tail end 114. The inner sidewall 116 is located between the tail end 114 and the internal space 117, that is, the inner sidewall 116 is formed by a groove recessed relative to the tail end 114. A second waterproof sleeve 134 is waterproofly fixed on the inner sidewall 116, and the end of the second waterproof sleeve 134 is located between the tail end 114 and the inner sidewall 116, so that the second waterproof sleeve 134 is covered below the tail end 114.

[0057] The lower cover 135 has a recessed groove 137 on one surface adjacent to the mating surface 113. The shape of the groove 137 matches the shape of the inner retaining wall 115, and a waterproof ring 139 is provided within the groove 137. The lower cover 135 is fixedly abutted against the mating surface 113. The inner retaining wall 115 fits into the groove 137 and presses against the waterproof ring 139, thus preventing water from entering the internal space 117 from the gap between the upper cover 111 and the lower cover 135.

[0058] The waterproof operation module 97 further includes an operation interface control circuit 152 and an operation interface 151 electrically connected to the operation interface control circuit 152. The operation interface 151 may, but is not limited to, be composed of a touch screen. The operation interface control circuit 152 is combined with a plurality of the connecting parts 131. The operation interface 151 is aligned with the opening 133. When the operation interface 151 is a touch screen, a transparent partition 155 is provided between the operation interface 151 and the inner end face 119. The area of ​​the transparent partition 155 is larger than the opening 133. The transparent partition 155, the operation interface 151, and the opening 133 are aligned, thus allowing the operation to proceed through the transparent partition 155. By operating the operating interface 151 (e.g., an operating interface 151 composed of a touch screen), water cannot enter the internal space 117 from the opening 133. The operating interface control circuit 152 is actually separated from the lower cover 135 by a distance. The operating interface control circuit 152 and the main control circuit 94 are electrically connected by a control line 154. The two ends of the control line 154 are respectively sealed to the second waterproof sleeve 134 and a first waterproof sleeve 86, so that the two ends of the control line 154 pass into the internal space 117 and the accommodating space 84 respectively, and water cannot enter the internal space 117 and the accommodating space 84 along the control line 154.

[0059] The waterproof operating module 97 is housed within the receiving opening 39 of the first portion 30 of the assembly frame 28 and abuts against the upper side of the second portion 42. The control line 154 passes through the gap between the first portion 30 and the waterproof operating module 97 and enters the chamber 44 through the perforation 45 of the second portion 42 (e.g., Figure 5 , Figure 9 As shown), the control line 154 can electrically connect the operating interface control circuit 152 and the main control circuit 94 without being exposed.

[0060] The plurality of waterproof electrical connectors 95 of the waterproof electrical control module 74 can be used to electrically connect to external power supplies, smoke machines, snow machines, bubble machines, and / or other stage effects equipment in a waterproof manner, enabling the fan unit 10 to operate independently or in conjunction with the stage effects equipment. For example, the fan unit 10 can be electrically connected to an external power supply and a snow machine, drawing power from the external power supply and cooperating with the snow machine to generate appropriate airflow to propel artificial snowflakes wider and / or farther.

[0061] The technical features of the present invention have been described in detail, and it should be understood from this description that the present invention includes at least the following advantages. For example, the waterproof operating module 97, the waterproof electrical control module 74, and the fan motor 48 are all waterproof, so the fan device 10 can be used outdoors without worrying about getting wet from rain.

[0062] The waterproof enclosure 82 of the housing 78 of the waterproof electrical control module 74 protrudes from the joint surface 80 and surrounds the outer perimeter of the accommodating space 84. Therefore, water is not easily seeped into the accommodating space 84 from the gap between the cover 88 and the housing 78. As a result, the first waterproof outer box 76 provides a good waterproof effect, and the main control circuit 94 is not easily damaged by water.

[0063] The operation interface control circuit 152 of the waterproof operation module 97 is fixed in the internal space 117 of the upper cover 111 and separated from the lower cover 135. The suspended setting of the operation interface control circuit 152 reduces the probability of contact with water.

[0064] The design of the downward-protruding inner baffle 115 in the upper cover 111 makes it difficult for water outside the second waterproof outer box 98 to enter the inner space 117, and further makes it difficult for the operation interface control circuit 152 to come into contact with water, thus providing a good waterproof effect.

[0065] The fan motor 48 is located within the installation space 36, and thus the outer periphery of the fan motor 48 is covered by the first part 30, preventing the fan motor 48 from being directly wetted by rain and reducing the probability of damage to the fan motor 48.

[0066] The waterproof electronic control module 74 is adjacent to the installation space 36 and located directly behind the fan blade 58. With the cooperation of a plurality of heat dissipation fins 78A, when the fan blade 58 is running, the airflow can pass through the plurality of heat dissipation fins 78A of the waterproof electronic control module 74, so that the temperature of the main control circuit 94 can be well controlled.

[0067] The fan motor 48 can be fitted with a high-viscosity sealing oil and an outer seal 53C through the shaft cover 53, which can effectively prevent water from entering the fan motor 48 from the gap between the front end face 48A and the shaft 48D.

[0068] The basic teachings of the present invention have been described, and many extensions and variations will be apparent to those skilled in the art. For example, the assembly frame 28 may also be a one-piece structure, in which case the assembly frame 28 can still provide mounting for the waterproof operating module 97, the waterproof electrical control module 74, and the fan motor 48.

[0069] Since the invention disclosed in this specification may be practiced in other specific forms without departing from the spirit or general characteristics of the invention, and some of these specific forms have been pointed out, the embodiments disclosed in this specification should be regarded as illustrative rather than limiting.
