Description

Technical Field

[0001] The utility model belongs to the technical field of photographing devices, and more specifically, relates to a camera cooling system and a waterproof housing for a camera. Background Art

[0002] During the process of taking pictures or videos, the internal electronic components of a camera will generate heat, and the heat is conducted through the body of the camera and dissipated into the air. Taking pictures is an intermittent action, and the amount of heat generated is not enough to affect the normal use of the camera. However, video recording is a continuous action. Especially when recording high-quality, high-frame-rate 4K or 8K videos, a large amount of heat will be generated inside the camera in a short period of time. If the heat is not dissipated in time, the working temperature of the main board will exceed the safety set value, and the main system of the camera will force a shutdown. The user can only restart the camera after waiting for the heat to dissipate or the temperature to drop to the safety set value.

[0003] During underwater photography, the camera is installed in a sealed waterproof housing. The heat generated inside the camera is first conducted through the body of the camera to the air inside the waterproof housing, and then dissipated to the external water or sea water through the waterproof housing. One of the heat dissipation solutions is to make the camera waterproof housing, the tray for installing the camera, etc. of aluminum alloy with good thermal conductivity, and then design a plurality of heat sink structures on it. By increasing the thermal conductivity of structural parts such as the waterproof housing and the tray and increasing the heat dissipation area, the heat transfer efficiency is improved. Although the above natural heat dissipation or cooling methods have some positive effects, they still cannot significantly extend the duration of the camera recording high-quality, high-frame-rate 4K or 8K videos.

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0032] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0033] It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0034] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, the meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0035] During underwater photography, the camera is installed inside a sealed waterproof housing. The heat generated inside the camera is first conducted through the camera body to the air inside the waterproof housing, and then dissipated to the external water or seawater through the waterproof housing. One of the heat dissipation solutions is to make the camera waterproof housing, the tray for installing the camera, etc. of aluminum alloy with good thermal conductivity, and then design a plurality of heat sink structures on it. By changing the material of the housing, designing the heat sink structure, etc., the heat dissipation efficiency that can be improved is limited. When shooting high-quality, high-frame-rate videos, a large amount of heat will be generated quickly. Using the current heat dissipation structure, the heat cannot be dissipated quickly to the outside, resulting in a large amount of heat accumulation inside the camera, an increase in temperature, and affecting the normal operation of the camera.

[0036] To alleviate the above technical problems, an embodiment of the present utility model provides a camera cooling system 100 and a camera waterproof housing. The camera cooling system 100 is disposed inside the housing structure 300, and the fan assembly 30 can generate an air flow and flow towards the structure to be cooled of the camera, accelerating the air flow speed inside the camera, actively dissipating heat from the camera, and extending the shooting duration of the camera.

[0037] Now, the camera cooling system 100 provided by the embodiment of the present utility model will be described.

[0038] Please refer to Figures 1 to 4 , the camera cooling system 100 is disposed inside the housing structure 300 and is used to improve the heat dissipation efficiency of the camera. The camera cooling system 100 includes a power supply 10, a circuit control component 20, a fan assembly 30, and a fixing member 40.

[0039] The power supply 10 is a structure for storing electrical energy and providing electrical energy for other components, and specifically can provide electrical energy for the circuit control component 20, the fan assembly 30, etc.

[0040] The circuit control component 20 can be used to control the turning on, turning off, and wind speed of the fan assembly 30. The circuit control component 20 has the function of conducting the power supply 10 and the fan assembly 30, and can enable the fan assembly 30 to work under a stable voltage.

[0041] The fan assembly 30 is capable of generating an air flow and directing the generated air flow to the structure to be cooled of the camera. Specifically, the fan assembly 30 has an air outlet, and the structure to be cooled has an air inlet, and the air outlet of the fan assembly 30 communicates with the air inlet of the structure to be cooled. The structure to be cooled can be a heat-generating component of the camera, a heat dissipation housing of the camera, etc. It should be noted that the air outlet of the fan assembly 30 and the air inlet of the structure to be cooled can be directly communicated, such as being arranged opposite to each other, or can be indirectly communicated through other components.

[0042] The power supply 10, the circuit control component 20 and the fan assembly 30 are electrically connected to form an electrically conductive loop. When the electrically conductive loop is turned on, the fan assembly 30 operates to direct an air flow to the structure to be cooled. When the electrically conductive loop is turned off, the fan assembly 30 stops operating.

[0043] The fixing member 40 is an installation structure of the camera cooling system 100, and the power supply 10, the circuit control component 20 and the fan assembly 30 are all arranged on the fixing member 40. The fixing member 40 can be a one-piece structure, and the power supply 10, the circuit control component 20 and the fan assembly 30 are all fixed on the fixing member 40, so that the camera cooling system 100 is an independently arranged module, which is convenient for the independent assembly, disassembly and installation of the camera cooling system 100; the fixing member 40 can also be a multi-piece structure, and the power supply 10, the circuit control component 20 and the fan assembly 30 can be respectively fixed on different fixing structures; the fixing member 40 can be a part of the housing structure 300.

[0044] The camera cooling system 100 in the above embodiments includes a power supply 10, a circuit control component 20, a fan assembly 30 and a fixing member 40. The power supply 10 provides electrical energy for the fan assembly 30. The circuit control component 20 controls the start and stop of the fan assembly 30. The air flow generated by the fan assembly 30 is directed to the structure to be cooled of the camera, accelerating the air flow inside the camera, realizing forced heat dissipation and doubling the duration of video recording.

[0045] In some embodiments of the present invention, the power supply 10 can be a rechargeable battery or a dry battery.

[0046] In some embodiments, the power supply 10 provides electrical energy for the camera cooling system 100. In other embodiments, the power supply 10 can be the power supply 10 of the camera body 200, and while supplying power to the camera body 200, it can also supply power to the camera cooling system 100.

[0047] In some embodiments of the present utility model, please refer to Figures 1 to 4 , the fan assembly 30 includes a fan body 31 and a wind guiding member 32. The air outlet 312 of the fan body 31 faces the air inlet 324 of the wind guiding member 32, and the air outlet 325 of the wind guiding member 32 faces the structure to be cooled.

[0048] The air guiding member 32 is used to guide the air flow so that the air flow flows along a predetermined path. The air guiding member 32 can be directly fixed to the fan body 31 or indirectly fixed to the fan body 31. The air guiding member 32 has an air inlet 324 and an air outlet 325, and the air inlet 324 and the air outlet 325 are in communication with each other. The direction from the air inlet 324 to the air outlet 325 is the extending direction of the air guiding member 32 and also the flowing direction of the air flow. The air flow generated by the fan body 31 flows out from its air outlet 312, and then flows through the air inlet 324 of the air guiding member 32 and the air outlet 325 of the air guiding member 32 to the structure to be cooled of the camera.

[0049] By providing the air guiding member 32, the air flow generated by the fan body 31 can be guided, so that the air flow generated by the fan body 31 can flow to the structure to be cooled as quickly as possible, avoiding the dissipation of the air flow at other positions of the camera, and at the same time, ensuring that the air flow has a relatively large flow velocity when reaching the structure to be cooled.

[0050] Among them, the fan body 31 generally includes a fan motor and blades. The fan motor drives the blades to rotate, thereby generating an air flow. The rotation axis of the blades of the fan body 31 can be referred to as the axial direction of the fan body 31, and the direction perpendicular to the axial direction of the fan body 31 is referred to as the radial direction of the fan body 31. The structure to be cooled is located on one side of the axial direction of the fan body 31, that is, the structure to be cooled and the fan body 31 are arranged in sequence along the axial direction of the fan body 31.

[0051] In some embodiments, the air outlet direction of the fan body 31 is parallel to the axial direction of the fan body 31, and the air guiding member 32 is located at one axial end of the fan body 31 and extends along the axial direction of the fan body 31. The fan body 31 discharges air along its axial direction, and the air flow passes through the air guiding member 32 and flows to the structure to be cooled of the camera along the axial direction of the fan body 31. Among them, one axial end of the fan body 31 refers to one end face in the axial direction of the fan body 31, specifically the end face adjacent to the air outlet side of the fan body 31. It can be understood that the air inlet 324 of the air guiding member 32 is located on the air outlet side of the fan body 31 at one axial end, and the air flow is guided to the required position through the extension of the air guiding member 32.

[0052] Optionally, the air guiding member 32 is fixed to the fan body 31 by a connecting member such as a screw. Or, the air guiding member 32 is fixed to the fixing member 40 by a connecting member such as a screw.

[0053] Optionally, the air guiding member 32 includes an air guiding cylinder 322 and a skirt portion 321 radially extending outward from the edge of the air guiding cylinder 322. The air guiding cylinder 322 is cylindrical, and its axial direction is parallel to or coincides with the axial direction of the fan body 31. A first connection hole 323 is formed in the skirt portion 321, and a second connection hole 311 is formed in the fan body 31. A first threaded member 33 passes through the first connection hole 323 and the second connection hole 311 to fix the air guiding member 32 to the fan body 31.

[0054] Optionally, a third connection hole 41 is formed in the fixing member 40. The first threaded member 33 passes through the first connection hole 323, the second connection hole 311 and is connected to the third connection hole 41 to fix both the air guiding member 32 and the fan body 31 to the fixing member 40.

[0055] In some embodiments, the air outlet direction of the fan body 31 is parallel to the radial direction of the fan body 31. The air guiding member 32 is located on the circumferential side wall of the fan body 31 and extends axially of the fan body 31 in a bent shape. The air outlet direction of the fan body 31 being parallel to the radial direction of the fan body 31 means that the air outlet 312 of the fan body 31 is located on the circumferential side wall of the fan body 31. The circumferential side wall of the fan body 31 refers to the side wall formed by the fan body 31 around its axis. The air inlet 324 of the air guiding member 32 faces the air outlet 312 of the fan body 31. After the air flow enters the air guiding member 32 from the fan body 31, it flows to the required position through the bent extension of the air guiding member 32.

[0056] Optionally, the fan body 31 is a turbo fan, and the air outlet 312 of the turbo fan is located on its side.

[0057] Optionally, the air guiding member 32 is arranged on one side of the fan body 31, and the air guiding member 32 is fixed to the fixing member 40. Specifically, the fan body 31 can be fixed to the fixing member 40 by a second threaded member 34, and the air guiding member 32 can be fixed to the fixing member 40 by a third threaded member 35.

[0058] Optionally, the air inlet direction and the air outlet direction of the air guiding member 32 are arranged at a right angle. Correspondingly, the air inlet 324 orientation and the air outlet 325 orientation of the air guiding member 32 are also perpendicular to each other. The air guiding member 32 is a bent structure.

[0059] In some embodiments of the present utility model, please refer to Figures 1 to 4, the circuit control component 20 includes a switching device 21 and a voltage stabilizing circuit. The power supply 10, the fan assembly 30, and the switching device 21 are all conducted through the voltage stabilizing circuit, and the switching device 21 is used to control the conduction and disconnection of the voltage stabilizing circuit. The voltage stabilizing circuit may include wires, traces on the circuit board, voltage stabilizing devices, etc., which are used to conduct the power supply 10, the fan assembly 30, the switching device 21, etc., to provide a stable voltage for the operation of the fan assembly 30. The switching device 21 is used to control the conduction and disconnection of the voltage stabilizing circuit, which can also be understood as controlling the turning on and off of the fan assembly 30. When the switching device 21 is closed, the fan assembly 30 starts to cool the heat dissipation structure to be cooled; when the switching device 21 is disconnected, the fan assembly 30 is turned off and is in an energy-saving state.

[0060] By setting the switching device 21, the camera cooling system 100 can be conducted when heat dissipation is required to cool the camera, and the camera cooling system 100 can be disconnected when heat dissipation is not required, improving the utilization efficiency of the power supply 10.

[0061] In some embodiments, the switching device 21 is a push-button switching device. For example, pressing the switching device 21 once conducts the voltage stabilizing circuit and the fan assembly 30 operates; pressing the switching device 21 again disconnects the voltage stabilizing circuit and the fan assembly 30 stops operating.

[0062] In some embodiments of the present utility model, please refer to Figures 1 to 4 , the camera cooling system 100 further includes an indicator light 23 for indicating the power level of the power supply 10, and the indicator light 23 is electrically connected to the circuit control component 20. The indicator light 23 is a device that can emit light, and different colors of light can represent different power levels, so that the power level of the power supply 10 can be judged by the change of the light color. Since the indicator light 23 is electrically connected to the circuit control component 20, the indicator light 23 is electrically connected to the power supply 10, the fan assembly 30, etc., so that the voltage or power level of the power supply 10 can be monitored, and the change of the power level of the power supply 10 can be displayed through the change of the color.

[0063] By setting the indicator light 23, the user can monitor the change of the power level of the power supply 10 in real time. When the power level of the power supply 10 is low to a preset value, the power supply 10 can be replaced or charged in time.

[0064] In some embodiments, the indicator light 23 is located on the voltage stabilizing circuit. When the switching device 21 is closed, the indicator light 23 is lit; when the switching device 21 is disconnected, the indicator light 23 is extinguished. In this way, it can be judged whether the voltage stabilizing circuit is working properly by whether the indicator light 23 is lit.

[0065] In some embodiments, the indicator light 23 can emit light of a first color and a second color. When the indicator light 23 is lit and shows the first color, it indicates that the power supply 10 has sufficient power. When the indicator light 23 is lit and shows the second color, it indicates that the power supply 10 has insufficient power and needs to be charged. For example, the first color is green and the second color is red. In other embodiments, the indicator light 23 can emit light of three colors: a first color, a second color, and a third color. When the indicator light 23 is lit and shows the first color, it indicates that the power supply 10 has sufficient power. When the indicator light 23 is lit and shows the second color, it indicates that the power of the power supply 10 is lower than a first preset value (such as 80%), which means the power is insufficient but it can still work normally. When the indicator light 23 is lit and shows the third color, it indicates that the power of the power supply 10 is lower than a second preset value (such as 10%), and it urgently needs to be charged. For example, the first color is green, the second color is yellow, and the third color is red.

[0066] Wherein, the number and specific colors of the light colors that the indicator light 23 can emit are not limited here, and the above embodiments are only for illustration.

[0067] In some embodiments, the number of the indicator lights 23 is multiple, and each indicator light 23 emits light of a different color. When different indicator lights 23 are lit, they respectively represent the corresponding power of the power supply 10. For example, the number of the indicator lights 23 is two, and the two indicator lights 23 respectively emit light of a first color and a second color. When the indicator light 23 of the first color is lit, it indicates that the power supply 10 has sufficient power. When the indicator light 23 of the second color is lit, it indicates that the power supply 10 has insufficient power and needs to be charged.

[0068] In some embodiments, the indicator light 23 is an LED, and LEDs are widely used and have low costs.

[0069] Please refer to Figures 5 to 8 , the present utility model also provides a waterproof housing for a camera. The waterproof housing for a camera includes the camera cooling system 100 in any of the above embodiments. The waterproof housing for a camera further includes a housing structure 300, and the camera cooling system 100 is disposed inside the housing structure 300. The inside of the housing structure 300 has an accommodation space, and the camera cooling system 100 is located in this accommodation space. The housing structure 300 has a protective effect on the camera cooling system 100.

[0070] The waterproof housing for a camera provided by the present utility model adopts the above-mentioned camera cooling system 100. The camera cooling system 100 includes a power supply 10, a circuit control component 20, a fan component 30, and a fixing member 40. The power supply 10 provides electrical energy for the fan component 30. The circuit control component 20 controls the start and stop of the fan component 30. The airflow generated by the fan component 30 is directed to the structure to be cooled of the camera, accelerating the air flow inside the camera, achieving forced heat dissipation and doubling the duration of video recording.

[0071] In some embodiments of the present utility model, the camera body 200 is disposed within the accommodation space of the housing structure 300. The camera body 200 is the main component of the camera. The camera body 200 includes components such as a lens and has a photographing function. Among them, the structure to be cooled can be a heat-generating component of the camera body 200 or a heat-dissipating housing, etc.

[0072] In some embodiments of the present utility model, the camera cooling system 100 is detachably connected to the housing structure 300, enabling the camera cooling system 100 to be integrally removed from the housing structure 300, facilitating charging of the power supply 10 or replacement. When the power supply 10 is a rechargeable battery, it is necessary to first remove the camera cooling system 100 from the housing structure 300, then charge the power supply 10. After charging is completed, the camera cooling system 100 is reinstalled to the housing structure 300. When the power supply 10 is a dry battery, it is necessary to first remove the camera cooling system 100 from the housing structure 300, then replace the battery with a new one, and finally reinstall the camera cooling system 100 to the housing structure 300.

[0073] In other embodiments, the camera cooling system 100 can also be fixed inside the housing structure 300, and the power supply 10 can be directly charged through the charging port on the housing structure 300.

[0074] In some embodiments of the present utility model, please refer to Figures 5 to 7 , the housing structure 300 includes a first housing 301 and a second housing 302 that are detachably connected. The first housing 301 is provided with a guide rail 304 and a locking device 306. The fixing member 40 is installed on the guide rail 304 and locked to the guide rail 304 through the locking device 306. The first housing 301 and the second housing 302 can be connected to each other or separated from each other. When the first housing 301 and the second housing 302 are connected to each other, the above-mentioned accommodation space is formed. The fixing member 40 is installed on the guide rail 304 and locked to the guide rail 304 through the locking device 306, which means that the fixing member 40 can slide along the guide rail 304. After the fixing member 40 slides into place, it is locked to the guide rail 304 through the locking device 306. When the first housing 301 and the second housing 302 are disassembled from each other, the locking device 306 can be first opened, and then the fixing member 40 can be slid off from the first housing 301, and thus the camera cooling system 100 can be slid off integrally.

[0075] By slidably arranging the fixing member 40 on the guide rail 304, the entire camera cooling system 100 can be slidably disassembled from the first housing 301, facilitating charging of the power supply 10 or replacement, and reducing the disassembly difficulty of the camera cooling system 100.

[0076] In some embodiments, please refer to Figure 7, the locking device 306 includes a rotating handle, an elastic member, and a locking pin. The rotating handle is rotatably connected to the first housing 301. The locking pin can extend into the guide rail 304 and can also withdraw from the guide rail 304. When installing the camera cooling system 100, first rotate the rotating handle to the right to a preset angle, driving the locking pin to move rightward and creating a passage in the guide rail 304; then insert both sides of the fixing member 40 into the two guide rails 304 respectively and push them in place, and then rotate the rotating handle to the left to the self-locking state ( Figure 6 as shown), when the rotating handle rotates, it drives the locking pin to move leftward and abuts against the slot 41 on the right edge of the fixing member 40 under the action of the internal elastic member, thereby locking the fixing member 40. When it is necessary to remove the camera cooling system 100, similarly rotate the rotating handle to the right to the preset angle, and then pull out the fixing member 40 outward.

[0077] In some embodiments, please refer to Figure 7 , the fixing member 40 is in a plate shape and can be regarded as the bottom plate of the camera cooling system 100. The number of guide rails 304 is two, and the opposite sides of the fixing member 40 are respectively located in the two guide rails 304, realizing the sliding connection between the fixing member 40 and the first housing 301.

[0078] In some embodiments, a slider is provided on the fixing member 40, and a chute is correspondingly provided on the first housing 301. The slider is slidably arranged in the chute, realizing the sliding connection between the fixing member 40 and the first housing 301.

[0079] In some embodiments, the fixing member 40 is limited by the first housing 301 and the second housing 302 in its sliding direction respectively, and the fixing member 40 is pressed in its sliding direction. In this way, when the camera cooling system 100 is installed inside the housing structure 300, the inner walls of the first housing 301 and the second housing 302 respectively abut against the opposite sides of the fixing member 40 (the opposite sides in the sliding direction), so that the fixing member 40 will not slide relative to the first housing 301.

[0080] In some embodiments, the camera is an ordinary digital camera or a waterproof camera, and can be used for underwater or deep-sea photography after being sealed and protected in a camera waterproof housing. Please refer to Figure 8 , the waterproof housing structure includes a first housing 301 and a second housing 302 that are detachably connected. A waterproof ring 303 is provided between the first housing 301 and the second housing 302, and further can seal the installation gap between the first housing 301 and the second housing 302.

[0081] In some embodiments of the present invention, please refer to Figure 8 and Figure 9, the housing structure 300 is provided with a switch hole 305, a key structure 50 is arranged at the switch hole 305, the circuit control component 20 includes a switching device 21 for controlling the fan component 30, and the key structure 50 is used for pressing the switching device 21. The switch hole 305 penetrates through the wall of the housing structure 300 and is arranged opposite to the switching device 21. A key structure 50 is arranged at the switch hole 305, which can be understood that at least part of the key structure 50 is located within the switch hole 305. One end of the key structure 50 protrudes from the outer surface of the housing structure 300, facilitating pressing the key structure 50 with a finger. The other end of the key structure 50 extends into the inner cavity of the housing structure 300 or is located within the switch hole 305 and is used for pressing the switching device 21.

[0082] By arranging the key structure 50 on the housing structure 300, the user can press the key structure 50 from the outside of the camera to control the switching device 21, thereby realizing the control of the fan component 30.

[0083] When it is necessary to shoot a video for a long time or to shoot a high-quality, high-frame-rate video, the key structure 50 can be pressed first to start the fan component 30, and then shooting can be started. Or the fan component 30 can be turned on during the process of shooting a video.

[0084] In some embodiments of the present invention, please refer to Figure 9 , the key structure 50 is spaced from the switching device 21 in the initial state, and the key structure 50 is in contact with the switching device 21 in the pressed state. The key structure 50 has an initial state and a pressed state: when the key structure 50 is in the initial state, the key structure 50 is not affected by an external force. One end of the key structure 50 is exposed outside the housing structure 300 for finger pressing, and the other end of the key structure 50 is spaced from the switching device 21 to form a safety distance to avoid accidentally touching the key structure 50 and causing the switching device 21 to be touched; when the key structure 50 is in the pressed state, it is affected by an external force, and the key structure 50 moves towards the switching device 21 and touches the switching device 21 under the action of the external force.

[0085] When the key structure 50 is in the initial state, a certain safety distance is formed between the key structure 50 and the switching device 21. Even if the key structure 50 is accidentally touched or the camera is in a vibration condition, the key structure 50 will not touch the switching device 21, so as to avoid accidentally starting the camera cooling system 100.

[0086] In some embodiments of the present invention, please refer to Figure 9, the switch hole 305 includes a first through hole 3051 and a second through hole 3052 that communicate with each other. The inner diameter of the first through hole 3051 is larger than that of the second through hole 3052; the key structure 50 includes a key shaft 51, a key cap 52, a touch head 53, an elastic member 54, and a limiting member 55. The key shaft 51 is disposed through the first through hole 3051 and the second through hole 3052. The key cap 52 is disposed at one end of the key shaft 51 and is located at the first through hole 3051. The touch head 53 is disposed at the other end of the key shaft 51 and is located between the inner wall of the housing structure 300 and the switch device 21. The two ends of the elastic member 54 are respectively connected to the key cap 52 and the end wall of the first through hole 3051 near the second through hole 3052. The limiting member 55 is fixed to the key shaft 51 near the touch head 53.

[0087] Both the first through hole 3051 and the second through hole 3052 are circular holes. Since the inner diameter of the first through hole 3051 is larger than that of the second through hole 3052, a limiting step is formed at the connection between the first through hole 3051 and the second through hole 3052. The first through hole 3051 is disposed near the outer wall of the housing structure 300, and the second through hole 3052 is disposed near the inner wall of the housing structure 300. The key cap 52 and the touch head 53 are respectively disposed at both ends of the key shaft 51. The key cap 52 is exposed outside the housing structure 300 and can be pressed by a finger. The touch head 53 is close to the switch device 21 and is used to touch the switch device 21. One end of the elastic member 54 can abut against or be fixed to the key cap 52, and the other end can abut against or be fixed to the limiting step. The limiting member 55 is used to limit the axial position of the key shaft 51, and the limiting member 55 can abut against the inner wall of the housing structure 300.

[0088] When the key structure 50 is in the initial state, the elastic member 54 is in a compressed state. Under the action of the restoring force of the elastic member 54, the limiting member 55 abuts against the inner wall of the housing structure 300. When the key structure 50 is in the pressed state, the elastic member 54 is further compressed, the limiting member 55 is separated from the housing structure 300, and the end of the key shaft 51 with the touch head 53 contacts the switch device 21.

[0089] In some embodiments, please refer to Figure 9 , the limiting member 55 includes a first gasket 551 and a snap ring 552. The snap ring 552 is snap-fitted and fixed to the outer ring of the key shaft 51. The first gasket 551 is sleeved on the key shaft 51, and the first gasket 551 is located between the snap ring 552 and the inner wall of the housing structure 300. When the key structure 50 is in the initial state, the first gasket 551 abuts against the inner wall of the housing structure 300 under the limiting action of the snap ring 552. In other embodiments, the limiting member 55 can also be a cylindrical structure and is fixed to the key shaft 51 through a connecting member such as a screw.

[0090] In some embodiments, please refer to Figure 9, an annular groove is provided at one end of the second through hole 3052 close to the first through hole 3051. A sealing ring 56 is arranged in the annular groove. A second gasket 57 is arranged between the elastic member 54 and the limiting step. The second gasket 57 abuts against the sealing ring 56 near the center to seal the gap between the key shaft 51 and the second through hole 3052. The second gasket 57 abuts against the limiting step near the edge.

[0091] Through the arrangement of the sealing ring 56, the gap between the key shaft 51 and the second through hole 3052 can be sealed. Even when the camera is used underwater, it is very difficult for water to enter the interior of the housing structure 300 through the switch hole 305.

[0092] In some embodiments of the present invention, the camera cooling system 100 further includes an indicator light 23 for indicating the power of the power supply 10. The indicator light 23 is electrically connected to the circuit control component 20. Since the indicator light 23 is electrically connected to the circuit control component 20, the indicator light 23 is electrically connected to the power supply 10, the fan assembly 30, etc. Thus, the voltage or power of the power supply 10 can be monitored, and the change of the power of the power supply 10 can be displayed by the change of color. There is a light-transmitting window on the housing structure 300. The light emitted by the indicator light 23 is emitted from the light-transmitting window. The user can judge the power of the power supply 10 from the light color at the light-transmitting window and charge the power supply 10 in time when the power of the power supply 10 is low.

[0093] In some embodiments, a light-transmitting opening is provided on the housing structure 300, and a transparent or translucent light-transmitting plate is provided at the light-transmitting opening.

[0094] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
