Description

Technical Field

[0001] This utility model belongs to the field of industrial cameras, and particularly relates to a sealing structure, camera and electronic equipment. Background Technology

[0002] Cooled industrial cameras typically cool their internal image sensors to below ambient temperature to ensure proper operation and meet imaging cooling requirements. However, when the image sensor temperature is below ambient, there is a risk of condensation affecting image quality. Therefore, the camera's internal cavity needs to be sealed and the internal gas kept dry to prevent condensation. Due to the sealed cavity, the use of related sealing components and the introduction of volatile organic compounds (VOCs) during the camera's PCB fabrication process can also contaminate the image sensor, leading to imaging problems.

[0003] However, existing technologies do not consider the issue of volatile organic compound (VOC) volatilization. By placing auxiliary materials such as sealing rings and sealants, which may pose a risk of volatile organic compound (VOC) volatilization, near the inner cavity, there is a risk that VOCs may volatilize and contaminate the image sensor.

[0004] To address this issue, this invention proposes a sealing structure that adjusts the sealing scheme in existing sealing structures. The polymer materials used for sealing, including sealing rings and sealant, are located outside the cavity or away from the image sensor area, reducing the risk of volatile organic compounds contaminating the image sensor. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned problems existing in the prior art, and to provide a sealing structure, camera and electronic device.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0007] A sealing structure for sealing at least one through groove on a housing to isolate the housing cavity from the outside, comprising:

[0008] A sealing component, installed on the outside of the housing, is used to seal the through groove;

[0009] A seal is installed on the outside of the plug to seal the plug and the housing, thereby isolating the inner cavity of the housing from the outside.

[0010] The sealing element forms a blocking section between itself and the housing. The blocking section is located between the inner cavity of the housing and the sealing element to prevent volatile organic compounds on the surface of the sealing element from entering the inner cavity of the housing.

[0011] Furthermore, the blocking portion is formed by the abutment between the sealing member and the housing.

[0012] Furthermore, an adsorption layer is provided on the contact surface between the sealing component and the housing for adsorbing volatile organic compounds.

[0013] Furthermore, the sealing component and the housing are respectively provided with matching bosses and grooves on their contact surfaces.

[0014] Furthermore, the blocking portion includes a blocking element located between the sealing element and the housing.

[0015] Furthermore, the blocking element is provided with an adsorption layer for adsorbing volatile organic compounds.

[0016] Furthermore, the sealing structure also includes:

[0017] Fasteners are used to secure plugs and seals.

[0018] A camera, comprising:

[0019] Such as the sealing structure described above;

[0020] The PCB, located inside the housing, is used for the electrical connection between the camera and the outside world;

[0021] An image sensor, located inside the housing, is used to acquire images.

[0022] Furthermore, the camera also includes:

[0023] The electrical interface connects to the PCB, and the connection point is coated with sealant.

[0024] An electronic device, including a camera as described above.

[0025] The beneficial effects of this utility model are:

[0026] 1. In this utility model, the through groove is sealed by a sealing member installed on the outside of the housing to achieve a preliminary seal between the inner cavity of the housing and the outside. A sealing member is further provided to enhance the sealing effect of the sealing member, so as to isolate the inner cavity of the housing from the outside and obtain a better sealed space in the inner cavity of the housing to avoid external contamination of the components in the inner cavity of the housing. Furthermore, the blocking part formed between the sealing member and the housing, and the blocking part is located between the inner cavity of the housing and the sealing member, prevents the organic volatiles on the surface of the sealing member from entering the inner cavity of the housing, and blocks the organic volatiles on the sealing member from entering the outside of the housing. At the same time, the blocking part can also further serve as a sealing unit to provide protection for the housing, improve the sealing effect of the sealing structure, and further prevent external contaminants from entering the inner cavity of the housing.

[0027] 2. In this utility model, by setting mutually cooperating bosses and grooves on the contact surface between the sealing component and the shell, the evaporation path length of volatile organic compounds entering the inner cavity of the shell is increased, thereby increasing the difficulty of volatile organic compounds evaporating into the inner cavity of the shell. The setting of bosses and grooves increases the obstacles on the evaporation path, thereby significantly improving the blocking effect of the blocking part. Furthermore, an adsorption layer for absorbing volatile organic compounds is set to reduce the risk of volatile organic compounds entering the inner cavity of the shell. Moreover, the blocking part, as another sealing unit of the sealing structure, adds another line of defense to prevent external pollutants from entering the inner cavity of the shell, thus improving the sealing effect.

[0028] 3. In this utility model, a sealing structure is provided in the camera to block the organic volatiles on the seal from entering the camera housing, thereby preventing the organic volatiles from entering the camera housing and causing image sensor contamination, affecting image acquisition quality or causing damage to the image sensor, thereby improving the image acquisition quality and stability of the camera. The high sealing performance of the sealing structure also ensures the stable airtightness inside the camera, preventing fogging on the surface of the image sensor from obstructing image acquisition.

[0029] 4. In this utility model, by adding sealant at the PCB and electrical interface, the airtightness of the camera is enhanced, preventing external contaminants from entering the camera. Furthermore, the sealant is applied to the side of the PCB away from the image sensor, limiting the entry of volatile organic compounds (VOCs) from the sealant into the camera and further reducing VOC contamination of the image sensor.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] The existing technology does not consider the issue of volatile organic compound (VOC) volatilization. By placing auxiliary materials such as sealing rings and sealants that may contain VOCs in the inner cavity, there is a risk that VOCs on the surface of the sealing rings or sealants will volatilize into the inner cavity of the housing and contaminate the inner cavity components.

[0038] To solve the above problems, firstly, as Figures 3-4 As shown, this utility model provides a sealing structure for sealing at least one through groove on a housing 1 to isolate the inner cavity of the housing 1 from the outside, comprising:

[0039] The sealing component 2 is installed on the outside of the housing 1 and is used to seal the through groove;

[0040] The sealing element 3 is installed on the outside of the sealing element 2 to seal the sealing element 2 and the housing 1, so as to isolate the inner cavity of the housing 1 from the outside.

[0041] In this process, a blocking part 4 is formed between the sealing member 2 and the housing 1. The blocking part 4 is located between the inner cavity of the housing 1 and the sealing member 3 to prevent the organic volatiles on the surface of the sealing member 3 from entering the inner cavity of the housing 1.

[0042] In this embodiment, by blocking and sealing the through groove on the housing 1, two non-interfering spaces are formed between the inner cavity of the housing 1 and the outside, so that external contaminants cannot enter the housing 1 and contaminate the inner cavity components.

[0043] In this embodiment, the function of the through slot is to connect the inner cavity of the housing 1 with the outside, so as to realize data interaction or transmission between the inner cavity of the housing 1 and the outside through the through slot. The number of through slots is not less than one, and each through slot needs to prevent the organic volatiles on the sealing member 2 from evaporating into the inner cavity of the housing 1.

[0044] In this embodiment, the surface area of ​​the sealing member 2 in contact with the through groove is larger than the area of ​​the through groove, so that the sealing member 2 completely covers the through groove and plays the role of sealing the through groove.

[0045] In this embodiment, the sealing element 2 is in close contact with the housing 1 so that the sealing element 2 can achieve a better sealing effect.

[0046] In this embodiment, the type of sealing element 3 includes, but is not limited to, sealing rings, sealing adhesives, sealing strips, sealing gaskets, etc. Its material can be flexible materials such as rubber and silicone, or rigid materials such as metal and graphite. Preferably, in this embodiment, the sealing element 3 is a sealing ring made of rubber, so as to effectively seal the contact surface between the sealing element 2 and the housing 1 through the sealing element 3.

[0047] In this embodiment, the sealing member 3 is installed on the outside of the sealing member 2. The outside of the sealing member 2 refers to the non-contact side between the sealing member 2 and the inner cavity of the housing 1, including the opposite side away from the inner cavity of the housing 1 and the peripheral side.

[0048] In this embodiment, a blocking part 4 is provided between the sealing member 2 and the housing 1. The blocking part 4 is located between the sealing member 3 and the inner cavity of the housing 1, so that the sealing member 3 is located outside the housing 1, so that the organic volatiles on the surface of the sealing member 3 are blocked outside the housing 1. At the same time, it can further improve the sealing effect of the sealing structure and prevent pollutants outside the housing 1 from entering the inner cavity of the housing 1.

[0049] In this invention, the through groove is sealed by the sealing member 2 installed on the outside of the housing 1 to achieve a preliminary seal between the inner cavity of the housing 1 and the outside. The sealing member 3 is further provided to enhance the sealing effect of the sealing member 2, so as to isolate the inner cavity of the housing 1 from the outside and obtain a better sealed space in the inner cavity of the housing 1 to avoid external contamination of the inner cavity components of the housing 1. Furthermore, the blocking part 4 formed between the sealing member 2 and the housing 1, and the blocking part 4 is located between the inner cavity of the housing 1 and the sealing member 3, prevents the organic volatiles on the surface of the sealing member 3 from entering the inner cavity of the housing 1, and blocks the organic volatiles on the sealing member 3 from the outside of the housing 1. At the same time, the blocking part 4 can also further serve as a sealing unit to provide protection for the housing 1, improve the sealing effect of the sealing structure, and further prevent external contaminants from entering the inner cavity of the housing 1.

[0050] In order to simplify the sealing structure and save manufacturing or production costs, and considering the limitations of installation space, in some embodiments, the blocking part 4 is formed by the abutment between the sealing member 2 and the housing 1.

[0051] In this embodiment, the blocking part 4 is the contact surface between the sealing member 2 and the housing 1. The contact surface formed by the tight fit between the sealing member 2 and the housing 1 serves as the blocking part 4, which isolates the sealing member 3 outside the housing 1 to prevent the volatile organic compounds on the surface of the sealing member 3 from evaporating into the inner cavity of the housing 1 and causing pollution.

[0052] In this embodiment, the blocking effect of the blocking part 4 on volatile organic compounds can be improved by increasing the area of ​​the contact surface between the sealing member 2 and the housing 1. Preferably, the evaporation path of volatile organic compounds can be increased by increasing the path length from the sealing member 3 to the inner cavity of the housing 1, thereby further improving the blocking effect on volatile organic compounds.

[0053] In order to improve the blocking effect of the blocking part 4 on volatile organic compounds, in some embodiments, an adsorption layer is provided on the contact surface between the sealing member 2 and the housing 1 for adsorbing volatile organic compounds.

[0054] In this embodiment, the adsorption layer can be disposed on the contact surface of the sealing component 2 and / or the housing 1. The adsorption layer can be made of materials that can absorb volatile organic compounds, including but not limited to activated carbon and adsorbents, and is used to effectively block the volatile organic compounds from entering the inner cavity of the housing 1.

[0055] In order to further improve the blocking effect of the blocking part 4 on volatile organic compounds, in some embodiments, the sealing part 2 and the shell 1 are respectively provided with matching bosses and grooves.

[0056] In this embodiment, a boss can be provided on the surface of the sealing component 2, and a groove adapted to the boss can be provided on the surface of the corresponding housing 1. Alternatively, a groove can be provided on the surface of the sealing component 2, and a boss adapted to the groove can be provided on the surface of the corresponding housing 1. The length of the volatile organic compound evaporation path can be increased by providing the boss and groove, and obstacles on the evaporation path can be increased by providing the boss and groove, so as to make the blocking effect significant.

[0057] In this embodiment, the shapes of the boss and the groove include, but are not limited to, common types such as rectangle, triangle, arc, and circle. They can also be irregular shapes. The boss and the groove do not need to be completely fitted together, or they can be partially fitted together. However, a complete and tight fit provides a better blocking effect.

[0058] In this invention, by providing mutually cooperating bosses and grooves on the contact surface between the sealing member 2 and the housing 1, the evaporation path length of volatile organic compounds entering the inner cavity of the housing 1 is increased, thereby increasing the difficulty for volatile organic compounds to evaporate into the inner cavity of the housing 1. The setting of bosses and grooves increases the obstacles on the evaporation path, thereby significantly improving the blocking effect of the blocking part 4. Furthermore, an adsorption layer for absorbing volatile organic compounds is provided to reduce the risk of volatile organic compounds entering the inner cavity of the housing 1. Moreover, the blocking part 4 serves as another sealing unit of the sealing structure, adding another layer of defense to prevent external pollutants from entering the inner cavity of the housing 1, thus improving the sealing effect.

[0059] In some embodiments, the blocking part 4 includes a blocking element located between the sealing element 2 and the housing 1.

[0060] In this embodiment, the blocking part 4 can also be a blocking part disposed between the sealing part 2 and the housing 1. In this case, the sealing part 2 and the housing 1 do not necessarily need to be in contact, but the blocking part effectively blocks the volatilization path of the organic volatiles.

[0061] In this embodiment, the connection between the blocking component and the sealing component 2 / shell 1 can be a fixed connection, a detachable connection, or a movable connection.

[0062] To further enhance the blocking effect of the blocking part 4 on volatile organic compounds, in some embodiments, the blocking element is provided with an adsorption layer for adsorbing volatile organic compounds.

[0063] In this embodiment, the adsorption layer is disposed on the blocking member, and the position of the adsorption layer on the blocking member can be arbitrarily distributed. Preferably, the adsorption layer is disposed on the side of the blocking member close to the sealing member 3, so as to fully absorb the volatile organic compounds.

[0064] To better install the sealing element 2 and the sealing element 3, and to make the sealing element 2 and the sealing element 3 fit more tightly against the housing 1, in some embodiments, the sealing structure further includes:

[0065] Fastener 5 is used to fasten the plug 2 and the seal 3.

[0066] In this embodiment, the fastener 5 presses the sealing member 2 tightly against the outside of the housing 1 to block the corresponding through groove, and the sealing member 3 tightly adheres to the sealing member 2 or the housing 1 to achieve a seal on the inner cavity of the housing 1.

[0067] In this embodiment, the fastener 5 and the housing 1 are fixed by means including but not limited to bolts, rivets, pins and other fixing methods.

[0068] In order to better fix the seal 3 and prevent slippage, the fastener 5 is also provided with a positioning groove for positioning the seal 3. The volume of the positioning groove is adapted to the seal 3. At the same time, in order to better fix the plug and the fastener 5, the housing 1 is also provided with a fixing groove for positioning the plug and the fastener 5.

[0069] In this embodiment, regarding the placement of the seal 3, on the one hand, it is necessary to ensure that the seal 3 is located outside the blocking part 4 so as to block the organic volatile molecules on the surface of the seal 3 through the blocking part 4. On the other hand, it is necessary to ensure that the path of external pollutants entering the inner cavity of the shell 1 is blocked by the seal 3 so as to fully isolate pollutants outside the shell 1 that are smaller in volume than organic volatile molecules.

[0070] Specifically, in this embodiment, the sealing element 3 is disposed in a pre-set positioning groove on the housing 1 and is located between the side of the sealing element 2 and the housing 1, so as to seal the path of external pollutants entering the inner cavity of the housing 1.

[0071] In another embodiment, the sealing element 3 is disposed in a pre-set positioning groove on the fastener 5, and there are two sealing elements 3, which respectively abut against the sealing element 2 and the fastener 5, and between the housing 1 and the fastener 5, so that the contact surfaces of the fastener 5 with the sealing element 2 and the housing 1 are sealed.

[0072] In addition, such as Figures 1-4 As shown, this utility model also provides a camera, including:

[0073] Such as the sealing structure described above;

[0074] PCB6, located inside housing 1, is used for electrical connection between the camera and the outside world;

[0075] Image sensor 7, located inside housing 1, is used to acquire images.

[0076] In this embodiment, the housing 1 serves as the camera housing to support the image sensor 7 and other components. One of the through slots on the surface of the housing 1 serves as the image acquisition port of the image sensor 7. The sealing component 2 of the image acquisition port is a glass cover plate, which is used to cooperate with the image acquisition port to realize image acquisition by the image sensor 7.

[0077] In this invention, a sealing structure is provided in the camera to block the volatile organic compounds on the seal 3 from entering the camera housing, thereby preventing the volatile organic compounds from entering the camera housing and causing contamination of the image sensor 7, affecting the image acquisition quality or causing damage to the image sensor 7, thereby improving the image acquisition quality and stability of the camera. The high sealing performance of the sealing structure also ensures the stable airtightness inside the camera, preventing fogging on the surface of the image sensor 7 from obstructing image acquisition.

[0078] To further improve the camera's sealing performance, in some embodiments, the camera further includes:

[0079] Electrical interface 8 is connected to PCB 6 and the connection is coated with sealant.

[0080] In this embodiment, the electrical interface 8 passes through another through slot in the housing 1, with one end connected to the PCB 6 inside the camera and the other end connected to the electrical equipment outside the camera. By adding sealant at the PCB 6 and the electrical interface 8, volatile organic compounds are prevented from being transmitted through the solder pins of the electrical interface 8 or the PCB 6 itself. Furthermore, the sealant is applied to the side of the PCB 6 away from the image sensor 7, further limiting the entry of volatile organic compounds in the sealant into the camera and contaminating the image sensor 7.

[0081] In this invention, by adding sealant at the PCB6 and electrical interface 8, the airtightness of the camera is enhanced, preventing external contaminants from entering the camera. Furthermore, the sealant is applied to the side of the PCB6 away from the image sensor 7, limiting the entry of volatile organic compounds (VOCs) from the sealant into the camera and further reducing VOC contamination of the image sensor 7.

[0082] To reduce contamination of the image sensor 7 by volatile organic compounds inside the camera, in some embodiments, the camera further includes:

[0083] Anti-fouling structure 9, used to reduce volatile organic compound (VOC) contamination of image sensor 7 on PCB 6, includes:

[0084] A condenser 91 is disposed between the PCB6 and the image sensor 7. The condenser 91 has an internal receiving chamber and an image acquisition port at the bottom.

[0085] The cooling element 92 has its cold end connected to the condenser 91 and is used to cool the condenser 91 so that the temperature of the condenser 91 is lower than that of the image sensor 7, so that volatile organic compounds condense on the condenser 91.

[0086] The image sensor 7 is located in the receiving chamber and its front end faces the image acquisition port. It is used to wrap the non-image acquisition surface of the image sensor 7 to block the diffusion path of volatile organic compounds to the image sensor 7.

[0087] In this embodiment, the anti-fouling structure 9 is used to reduce the pollution of the image sensor 7 by volatile organic compounds, so that the image sensor 7 can acquire images with higher image quality and operating status.

[0088] In this embodiment, since the image sensor 7 is limited by electrical connections and image acquisition paths, it is impossible to completely eliminate the pollution of volatile organic compounds. However, by setting the condenser 91 between the PCB6 and the image sensor 7, the evaporation path of volatile organic compounds on the PCB6 to the image sensor 7 is blocked, thereby minimizing the probability of volatile organic compounds polluting the image sensor 7 and thus protecting the image sensor 7.

[0089] In this embodiment, the accommodating chamber inside the condenser 91 is used to house the image sensor 7. The condenser 91 can also be adapted to be provided with an interface or line channel required for the electrical connection of the image sensor 7. The image acquisition port at the bottom of the condenser 91 is used for image acquisition by the photosensitive surface of the image sensor 7. This is to ensure that the image sensor 7 is completely enclosed as much as possible without affecting its working state, so as to block the diffusion path of volatile organic compounds to the image sensor 7 to the greatest extent and ensure the effectiveness of the image sensor 7.

[0090] In this embodiment, the cooling component 92 includes, but is not limited to, TEC, compressor refrigeration, magnetic refrigeration, and heat pipe refrigeration. In this embodiment, TEC is used as the cooling component 92, and the cold end of TEC is connected to the condenser 91 so that the condenser 91 is cooled down and the temperature is lower than that of the image sensor 7. This allows volatile organic compounds to preferentially condense on the condenser 91 at the lower temperature, thereby reducing the contamination of the image sensor 7 by volatile organic compounds.

[0091] In this embodiment, the image sensor 7 generates heat when it is in operation. For working environments with high image quality requirements, the image sensor 7 also needs to be cooled. However, due to the heat accumulation of the image sensor 7 itself, the temperature of the image sensor 7 is often higher than that of the condenser 91. This is to ensure that the condenser 91 maintains a better condensation and anti-fouling effect. Alternatively, by improving the cooling effect of the cooling component 92, the temperature of the condenser 91 can always be lower than that of the image sensor 7, thereby ensuring the condensation effect of the condenser 91 on volatile organic compounds and reducing the contamination of the image sensor 7.

[0092] In this invention, a condenser 91 is disposed between the PCB6 and the image sensor 7 to block the evaporation path of volatile organic compounds (VOCs) onto the image sensor 7, thereby reducing the amount of VOCs evaporating from the PCB6 onto the image sensor 7. The condenser 91 also includes a receiving chamber for the image sensor 7 and an image acquisition port for its own operation. This ensures normal image acquisition by the image sensor 7 while improving the encapsulation of the image sensor 7 by the condenser 91, maximizing the blocking of VOCs from diffusing to the image sensor 7. Furthermore, a cooling component 92 is also provided, with its cold end connected to the condenser 91, to cool the condenser 91 so that its temperature is lower than that of the image sensor 7. This causes VOCs to preferentially condense on the cooler condenser 91, further reducing the probability of VOCs evaporating and condensing on the image sensor 7. This optimizes the working environment of the image sensor 7 and improves image acquisition quality and lifespan.

[0093] The condenser 91 can take many forms. Specifically, as long as it can accommodate the image sensor 7 without obstructing the image acquisition path and has the function of condensing volatile organic compounds, it falls within the protection scope of this utility model. In some embodiments, the condenser 91 includes:

[0094] The first condenser plate 911 is connected to the refrigeration component 92 at its top;

[0095] Several second condensing plates 912 are disposed on the side of the first condensing plate 911, bent and extended to the bottom of the image sensor 7 to cooperate with the first condensing plate 911 to form a receiving chamber.

[0096] In this embodiment, both the first condensing plate 911 and the second condensing plate 912 are made of materials with high thermal conductivity, including but not limited to thermally conductive metals and alloy materials. In this embodiment, both the first condensing plate 911 and the second condensing plate 912 are made of copper as the preparation material. The high thermal conductivity of copper is used as the preparation material of the condensing component 91 so that the cooling component 92 can quickly and comprehensively cool the condensing component 91, ensuring that the condensing component 91 has a good condensation effect.

[0097] In this embodiment, the top of the first condensing plate 911 is connected to the cold end of the cooling component 92 so that the cooling component 92 can quickly cool down the first condensing plate 911.

[0098] In this embodiment, a plurality of second condensing plates 912 are fixedly disposed on the side of the first condensing plate 911. The second condensing plate 912 has a U-shaped cross section and bends towards the side close to the image sensor 7 and extends to the non-image acquisition path at the bottom of the image sensor 7 to wrap the image sensor 7 to form a receiving chamber. It also extends to the non-image acquisition path at the bottom of the image sensor 7 to open an image acquisition port for image acquisition by the image sensor 7.

[0099] In this embodiment, the number of second condensing plates 912 and their positions on the first condensing plate 911 are adaptively set based on the wiring requirements of the image sensor 7, so as to facilitate normal image acquisition by the image sensor 7.

[0100] In some embodiments, the condenser 91 includes:

[0101] A hollow condenser shroud is connected to the refrigeration component 92 at the top and has an opening at the bottom.

[0102] The image sensor 7 is located inside the hollow condenser shroud, with its front end facing the bottom opening of the hollow condenser shroud for image acquisition.

[0103] In this embodiment, another form of the condenser 91 is a hollow condenser cover with a hollow structure. The hollow area of ​​the hollow condenser cover serves as a cavity for accommodating the image sensor 7, so that the image sensor 7 is better enclosed and the evaporation path of volatile organic compounds is blocked. The bottom of the hollow condenser cover is provided with an opening as an image acquisition port for the image sensor 7.

[0104] In this embodiment, the hollow condenser cover may also be adapted to provide openings for electrical connection or cooling of the image sensor 7, so as to ensure the normal use of the image sensor 7.

[0105] To further reduce the contamination caused by the volatilization of volatile organic compounds onto the image sensor 7, in some embodiments, the surface of the condenser 91 is provided with an adsorption layer for adsorbing volatile organic compounds.

[0106] In this embodiment, the adsorption layer may be made of materials that can absorb volatile organic compounds, including but not limited to activated carbon and adsorbents, for absorbing volatile organic compounds. The adsorption layer may be located on the outer or inner surface of the condenser 91. Preferably, the adsorption layer is located on the outer surface of the condenser 91 to cover the evaporation path of the volatile organic compounds as much as possible.

[0107] To further enhance the adsorption effect of volatile organic compounds, in some embodiments, the top of the condenser 91 is provided with a groove, which is connected to the cold end of the refrigeration component 92, and an adsorbent is provided inside the groove for adsorbing volatile organic compounds.

[0108] In this embodiment, the groove is connected to the cooling component 92 so that the groove forms a low-temperature area relative to the condenser 91, which better condenses the volatile organic compounds. The groove also works with the adsorbent in the groove to absorb the volatile organic compounds, thereby preventing the accumulation of volatile organic compounds on the condenser 91 and maintaining the condensation effect of the condenser 91.

[0109] In order to save costs and optimize space, in some embodiments, the condenser 91 is connected to the non-image sensor 7 so that the cooling element 92 can simultaneously cool the condenser 91 and the image sensor 7.

[0110] In this embodiment, by sharing the same cooling unit 92 with the image sensor 7 and the condenser 91, not only are some of the cooling requirements of the image sensor 7 met, but the cooling device for cooling the image sensor 7 is also saved, thus optimizing the space used by the camera.

[0111] In this embodiment, the connection between the condenser 91 and the image sensor 7 can be a direct connection via contact heat conduction. In this case, the cooling component 92 cools the condenser 91 and directly cools the image sensor 7 through the condenser 91. Alternatively, it can be an indirect connection via a heat-conducting component. In this case, the cooling component 92 cools the condenser 91, and the condenser 91 indirectly cools the image sensor 7 through the heat-conducting component. Since the image sensor 7 generates its own heat, the temperature of the condenser 91 is always lower than that of the image sensor 7, thus maintaining a good condensation effect for the condenser 91.

[0112] In this invention, the condenser 91 is connected to the non-image-taking surface of the image sensor 7, so that the cooling element 92 can simultaneously cool the condenser 91 and the image sensor 7. This satisfies the need to cool the image sensor 7, saves cost and space by sharing the cooling element 92, and utilizes the heat generation characteristics of the image sensor 7 to make the temperature of the image sensor 7 higher than that of the condenser 91, thus ensuring the condensation effect of the low-temperature region of the condenser 91 on volatile organic compounds.

[0113] Finally, this invention provides an electronic device, including the camera described above.
