Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to an interactive all-in-one machine. Background Technology

[0002] With the continuous advancement and development of display device technology, users' functional requirements for intelligent interactive devices are increasing. Interactive all-in-one machines, by integrating touch and display functions to achieve human-computer interaction, significantly enhance the user experience and are increasingly widely used in outdoor public display fields.

[0003] To meet the demands of clear display in outdoor environments, interactive whiteboards are typically designed to be large, and require high-brightness backlights to maintain screen visibility under direct sunlight during the day. This significantly increases energy consumption and heat generation during operation. Furthermore, the combined effects of high outdoor temperatures and solar radiation exacerbate heat buildup inside the device, easily leading to performance degradation or malfunctions due to heat accumulation, necessitating improvements. Summary of the Invention

[0004] This application provides an interactive all-in-one machine that can improve the problem of insufficient heat dissipation in traditional interactive all-in-one machines, and ensure the stable operation of the interactive all-in-one machine in outdoor strong light and high temperature scenarios.

[0005] This application provides an interactive all-in-one machine, which includes:

[0006] The housing is provided with an air inlet and an air outlet;

[0007] A touch screen is connected to the housing and forms a mounting cavity with the housing;

[0008] A display module is disposed within the mounting cavity and connected to the housing, and spaced apart from the touchscreen.

[0014] In some embodiments, an air guide shroud is also included, which has an air inlet and an air outlet. The air guide shroud is connected to the housing and covers the periphery of the air outlet, and the air outlet communicates with the air outlet. The cooling fan is connected to the air guide shroud and is located at the air inlet.

[0015] In some embodiments, the housing has a rear shell wall and a top wall and a bottom wall respectively connected to opposite sides of the rear shell wall. The rear shell wall is disposed opposite to the side of the display module facing away from the touch screen. The rear shell wall is provided with the air inlet and the air outlet.

[0016] The air guide shroud includes a mounting plate and a guide plate, both of which are connected to the rear shell wall. The exhaust port is formed between the end of the mounting plate near the rear shell wall and the end of the guide plate near the rear shell wall. The air inlet is provided on the mounting plate. The cooling fan is connected to the mounting plate. The guide plate is closer to the bottom wall than the mounting plate. Both the mounting plate and the guide plate are set at an angle to the rear shell wall.

[0017] In some embodiments, in the direction from the top wall to the bottom wall, the distance between the mounting plate and the rear shell wall gradually increases, and the distance between the guide plate and the rear shell wall gradually decreases.

[0018] And / or, the cooling fan is provided in multiple ways, the mounting plate is provided with multiple air inlets, and one cooling fan is located at one of the air inlets.

[0019] In some embodiments, the air guide shroud further includes a connecting plate, with the mounting plate and the air guide plate respectively connected to opposite sides of the connecting plate. The interactive all-in-one machine also includes an adapter circuit board, which is connected to the side of the connecting plate away from the rear shell wall and electrically connected to the cooling fan.

[0020] In some embodiments, the edge of the air outlet near the bottom wall is aligned with the edge of the guide plate near the bottom wall.

[0021] In some embodiments, the housing has a rear shell wall and a top wall and a bottom wall respectively connected to opposite sides of the rear shell wall. The rear shell wall is disposed opposite to the side of the display module facing away from the touch screen. The rear shell wall is provided with the air inlet and the air outlet.

[0022] The interactive all-in-one machine also includes a support shell and a filter component. The support shell is connected to the rear shell wall and covers the periphery of the air inlet. The support shell and the rear shell wall enclose a partition cavity that communicates with the air inlet. The support shell has an air outlet that communicates with the partition cavity. The filter component is connected to the side of the support shell away from the rear shell wall and covers the air outlet.

[0023] In some embodiments, the cross-section of the partition cavity gradually decreases in the direction from the top wall toward the bottom wall.

[0024] In some embodiments, the edge of the air inlet near the bottom wall is aligned with the bottom of the partition cavity.

[0025] In some embodiments, the housing further includes two grille supports, with opposite ends of the grille supports connected to the side of the display module near the touch screen and the outer casing, respectively. At least a portion of one grille support is located at the air inlet of the second air duct, and at least a portion of the other grille support is located at the air outlet of the second air duct.

[0026] In some embodiments, the housing has a rear shell wall and a top wall and a bottom wall respectively connected to opposite sides of the rear shell wall. The rear shell wall is disposed opposite to the side of the display module facing away from the touch screen. The rear shell wall is provided with the air inlet and the air outlet.

[0027] The housing also includes two air guide baffles, which are located between the side of the display module facing the touch screen and the outer shell, and together with the display module and the touch screen, form the second air duct. The ends of the two air guide baffles near the top wall define the outlet of the second air duct with the display module and the touch screen, respectively, and the ends of the two air guide baffles near the bottom wall define the inlet of the second air duct with the display module and the touch screen, respectively.

[0028] Based on the above embodiments, a first air duct is formed by cooperating with the housing on the side of the display module facing away from the touch screen, and a second air duct is formed between the display module and the touch screen. The inlets of both are connected to the air inlet, and the outlets are connected to the air outlet. At the same time, the cooling fan drives the external airflow to be drawn into the mounting cavity from the air inlet, so that the airflow flows through both sides of the display module (the side facing away from the touch screen and the side facing the touch screen), thereby simultaneously dissipating heat from both sides of the display module. The heat generated by the display module and surrounding components during operation is effectively carried away from both sides by the airflow, which significantly increases the air circulation efficiency in the mounting cavity. Compared with single-air duct heat dissipation, the dual-air duct structure can more comprehensively cover the heat-generating area, improve the problem of insufficient heat dissipation in traditional interactive all-in-one machines, thereby avoiding equipment failure caused by poor heat dissipation in high-temperature environments and ensuring the stable operation of the interactive all-in-one machine in outdoor strong light and high-temperature scenarios.

[0046] With the continuous advancement and development of display device technology, users' functional requirements for intelligent interactive devices are constantly increasing. Interactive all-in-one machines, by integrating touch and display functions to achieve human-computer interaction, significantly enhance the user experience and are increasingly widely used in outdoor public display fields. To meet the clear display requirements in outdoor environments, interactive all-in-one machines are typically designed to be large, and require high-brightness backlights to maintain image visibility under strong sunlight during the day. This significantly increases energy consumption and heat generation during operation. Simultaneously, the combined effects of high outdoor temperatures and solar radiation further exacerbate heat accumulation inside the device, easily leading to performance degradation or malfunctions due to heat buildup, necessitating improvements.

[0047] To resolve the above issues, please refer to [link / reference]. Figures 1 to 4 The first aspect of this application proposes an interactive all-in-one machine 100, which can be an outdoor all-in-one machine, an indoor touch screen all-in-one machine, an educational all-in-one machine, or a commercial display all-in-one machine, etc. In the embodiments of this application, the interactive all-in-one machine 100 includes a housing 10, a touch screen 20, a display module 30, and a cooling fan 40.

[0048] The outer contour of the housing 10 is generally rectangular, and its wall surface is provided with an air inlet 1111 and an air outlet 1112. The air inlet 1111 and the air outlet 1112 can be circular openings, and multiple air inlets 1111 and air outlets 1112 are provided on the same wall surface (e.g., the rear wall) of the housing 10. The multiple air inlets 1111 and air outlets 1112 are arranged in an array, with uniform spacing between each opening to increase the air flow area, effectively improve the air volume, and thus enhance the air convection efficiency inside the housing 10.

[0049] The touchscreen 20 is connected to the housing 10 and together with the housing 10 forms a mounting cavity 10A. The touchscreen 20 can be capacitive, infrared, resistive, surface acoustic wave, optical imaging, electromagnetic induction, or pressure-sensitive. The touchscreen 20 can be rectangular, with a corresponding rectangular opening on the housing 10. The touchscreen 20 is embedded in and fixed within the rectangular opening, and the two together form a closed mounting cavity 10A, providing installation space for internal components such as the display module 30 and the cooling fan 40.

[0050] The display module 30 is disposed within the mounting cavity 10A and connected to the housing 10, and is spaced apart from the touch screen 20. The side of the display module 30 facing away from the touch screen 20 forms a first air duct 10a with the housing 10. The display module 30, housing 10, and touch screen 20 together form a second air duct 10b located between the display module 30 and the touch screen 20. The inlets of the first air duct 10a and the second air duct 10b are both connected to an air inlet 1111, and the outlets of the first air duct 10a and the second air duct 10b are both connected to an air outlet 1112.

[0051] The display module 30 can adopt common display technologies such as LCD, LED, and OLED. Its shape is usually adapted to the touch screen 20. For example, when the touch screen 20 is rectangular, the display module 30 is also rectangular to ensure that when the two are spaced apart in the mounting cavity 10A, the display area can completely cover the touch operation area. At the same time, it is convenient to form a regular first air duct 10a between the side of the display module 30 facing away from the touch screen 20 and the inner wall of the housing 10, and to form a second air duct 10b between the display module 30 and the touch screen 20 and enclosed by the housing 10, so that the structure of the two air ducts is more regular and conducive to uniform airflow.

[0052] A cooling fan 40 is disposed within the mounting cavity 10A and adjacent to the air outlet 1112. The cooling fan 40 drives external airflow into the mounting cavity 10A through the air inlet 1111, flows through the first air duct 10a and the second air duct 10b respectively, and is then discharged from the air outlet 1112. The cooling fan 40 can be an axial fan, a centrifugal fan, or a mixed-flow fan, etc. The fan can be equipped with a speed control module to automatically adjust the speed according to the operating temperature of the equipment, thereby reducing energy consumption and noise while meeting the heat dissipation requirements.

[0053] Based on the above embodiments, a first air duct 10a is formed by the display module 30 on the side facing away from the touch screen 20 and the housing 10, and a second air duct 10b is formed between the display module 30 and the touch screen 20. The inlets of both are connected to the air inlet 1111 and the outlets are connected to the air outlet 1112. At the same time, the cooling fan 40 drives the external airflow to be drawn into the mounting cavity 10A from the air inlet 1111, so that the airflow flows through both sides of the display module 30 (the side facing away from the touch screen 20 and the side facing away from the touch screen 20), thereby simultaneously dissipating heat from both sides of the display module 30. The heat generated by the display module 30 and its surrounding components during operation is effectively carried away from both sides by the airflow, significantly increasing the air circulation efficiency in the mounting cavity 10A. Compared with single-duct heat dissipation, the dual-duct structure can more comprehensively cover the heat-generating area, improving the problem of insufficient heat dissipation of traditional interactive all-in-one machines 100, thereby avoiding equipment failure caused by poor heat dissipation in high-temperature environments and ensuring the stable operation of the interactive all-in-one machine 100 in outdoor strong light and high-temperature scenarios.

[0054] Reference Figures 3 to 5 In some embodiments, the housing 10 includes an outer shell 11 and a partition 12. The touch screen 20 is connected to the outer shell 11 and forms a mounting cavity 10A with the outer shell 11. The outer shell 11 and the partition 12 can be made of metal materials such as aluminum alloy or steel, utilizing the good thermal conductivity of metal to assist in heat dissipation of the device, while improving the structural strength of the housing 10 to adapt to complex outdoor environments.

[0055] The outer casing 11 includes a rear casing wall 111 and a top wall 112 and a bottom wall 113 connected to opposite sides of the rear casing wall 111. The rear casing wall 111 is positioned opposite the side of the display module 30 facing away from the touch screen 20, and its surface is provided with an air inlet 1111 and an air outlet 1112. The air inlet 1111 and the air outlet 1112 can be distributed in different areas of the rear casing wall 111 according to the principle of air convection (e.g., the air inlet 1111 is near the bottom wall 113, and the air outlet 1112 is near the top wall 112), utilizing the rising characteristics of hot air to assist in heat dissipation. The top wall 112 and the bottom wall 113 can cooperate with the rear casing wall 111 to form a stable support frame, facilitating the installation and fixation of various components. The air inlet 1111 and air outlet 1112 are concentrated on the rear shell wall 111, which reduces the number of openings on other walls of the shell 11, lowering the risk of dust, rainwater, and other foreign objects entering the mounting cavity 10A from the side or top in outdoor environments, and improving the equipment's protective performance. Simultaneously, the air inlet 1111 and air outlet 1112 on the same wall facilitate the formation of straight or short-path convection channels for airflow within the shell 10, reducing airflow turning losses. This allows the cooling fan 40 to drive external airflow more smoothly into and out of the shell 11, enhancing air exchange efficiency and simplifying the processing and assembly of the shell 11, reducing structural design complexity. Alternatively, an additional air inlet 1111 can be provided directly on the bottom wall 113, allowing external airflow to enter the second air duct 10b more quickly.

[0056] The partition 12 is located within the mounting cavity 10A and connected to the outer casing 11. The partition 12 and the outer casing 11 cooperate to form a guide channel 10c that connects the outlet of the second air duct 10b and the air outlet 1112. Simultaneously, the partition 12, the outer casing 11, and the side of the display module 30 facing away from the touch screen 20 cooperate to form the first air duct 10a. The cooling fan 40 is mounted on the partition 12, partially located within the first air duct 10a and partially within the guide channel 10c. Based on this structure, the partition 12 effectively divides the first air duct 10a and the guide channel 10c, allowing the airflow from the second air duct 10b to converge orderly to the air outlet 1112 through the guide channel 10c, avoiding airflow turbulence. The cooling fan 40's arrangement across both sides of the partition 12 ensures that it can simultaneously draw in and accelerate the airflow within the first air duct 10a, and efficiently export the airflow through the guide channel 10c, forming a continuous heat dissipation path. This design further optimizes the airflow within the interactive all-in-one machine 100. Heat from the side of the display module 30 facing away from the touchscreen 20 can be exhausted through the first air duct 10a via the cooling fan 40 and the guide channel 10c. Heat between the display module 30 and the touchscreen 20 can be exhausted through the second air duct 10b via the guide channel 10c. The combination of the dual air ducts and the guide channel 10c enhances overall heat dissipation efficiency and reduces heat retention within the mounting cavity 10A, thus more reliably ensuring the device's heat dissipation performance under high load operation and improving the environmental adaptability and operational stability of the interactive all-in-one machine 100. Furthermore, the housing 10 also includes a support frame, which can be connected to the side of the partition 12 near the bottom wall 113 and located within the first air duct 10a. This support frame can be used to support the side of the display module 30 facing away from the touchscreen 20. Meanwhile, the interactive all-in-one machine 100 also includes heat source components such as a power module and a control module, which can be mounted on a support frame. In this way, the airflow of the first air duct 10a can also dissipate heat from the power module, control module, and other heat source components.

[0057] Reference Figure 6 and Figure 7 Furthermore, the partition 12 is provided with a mounting port 121, into which the cooling fan 40 is embedded. The edge of the mounting port 121 can form a limiting structure (such as a step, a buckle, or a flange) to accurately position the cooling fan 40, ensuring that the fan's air intake or exhaust port 50B is aligned with the air duct inlet or outlet, thus avoiding airflow leakage or increased resistance due to installation misalignment. Through the limiting effect of the mounting port 121, the vibration of the cooling fan 40 during operation can be effectively suppressed, improving the stability of component installation. At the same time, it ensures a tight fit between the cooling fan 40 and the partition 12, guaranteeing unobstructed airflow between the first air duct 10a and the guide channel 10c, thereby optimizing the overall heat dissipation efficiency.

[0058] Reference Figure 4 , Figure 6 as well as Figure 7 In some embodiments, the interactive all-in-one machine 100 further includes an air guide shroud 50, which has an air inlet 50A and an air outlet 50B. The air guide shroud 50 is connected to the outer shell 11 and covers the periphery of the air outlet 1112, with the air outlet 1112 communicating with the air outlet 50B. The cooling fan 40 is connected to the air guide shroud 50 and located at the air inlet 50A. The air guide shroud 50 provides physical support for the cooling fan 40 and isolates the area surrounding the air outlet 1112 from the external environment through its structure, guiding airflow along a preset path, reducing turbulence, and improving exhaust efficiency. The air inlet 50A, in conjunction with the fan's position, allows air drawn in by the fan to directly enter the interior of the air guide shroud 50, be guided, and then evenly discharged, preventing disordered airflow near the air outlet 1112. This optimizes the airflow organization of the entire cooling system and enhances the heat dissipation stability of the interactive all-in-one machine 100 during operation.

[0059] Furthermore, the air guide shroud 50 includes a mounting plate 51 and a guide plate 52, both of which are connected to the rear shell wall 111. Specifically, the two can be fixed to the rear shell wall 111 by means of screws or other methods. For example, pre-set screw holes are provided around the air outlet 1112 of the rear shell wall 111, and mounting holes are opened at corresponding positions on the mounting plate 51 and the guide plate 52. Screws are passed through the mounting holes and fastened to the screw holes.

[0060] An exhaust port 50B is formed between one end of the mounting plate 51 near the rear shell wall 111 and the other end of the guide plate 52 near the rear shell wall 111. The mounting plate 51 has an air inlet 50A. A cooling fan 40 is connected to the mounting plate 51. The guide plate 52 is closer to the bottom wall 113 than the mounting plate 51. The mounting plate 51 and the rear shell wall 111 are set at an angle. This means the cooling fan 40 is tilted along with the mounting plate 51 and the rear shell wall 111, creating a staggered design between the cooling fan 40 and the exhaust port 1112. Furthermore, the cooling fan 40 is positioned relatively closer to the top wall 112, effectively reducing direct splashing of rainwater onto the surface of the cooling fan 40 and improving its waterproof performance.

[0061] The air deflector 52 is set at an angle to the rear shell wall 111. This angled layout can optimize the airflow path from the air inlet 50A through the cooling fan 40 to the air outlet 50B, reduce wind resistance, and allow the airflow to be discharged more smoothly through the air deflector 52. While accelerating the exhaust efficiency, the airflow can also be used to blow out rainwater that may enter the air outlet 1112, further enhancing the equipment's protection capability in severe weather.

[0062] Furthermore, in the direction from the top wall 112 to the bottom wall 113, the distance between the mounting plate 51 and the rear shell wall 111 gradually increases, meaning that the mounting plate 51, starting from a position close to the top wall 112, gradually moves away from the rear shell wall 111 as it extends towards the bottom wall 113, forming an outwardly expanding inclined angle. The distance between the guide plate 52 and the rear shell wall 111 gradually decreases. That is, as the guide plate 52 extends from a position close to the top wall 112 towards the bottom wall 113, it gradually approaches the rear shell wall 111, forming an inwardly converging inclined angle. This differentiated spacing creates an "outward expansion and inward contraction" spatial layout between the mounting plate 51 and the guide plate 52 in the vertical direction. This layout expands the air intake range of the air inlet 50A area through the outward expansion structure of the mounting plate 51, allowing external airflow to enter the air guide shroud 50 more smoothly through the cooling fan 40. At the same time, the inward contraction design of the guide plate 52 can converge and guide the airflow, reduce turbulence in the air duct, and improve the speed and directionality of the airflow discharged from the exhaust port 50B. Meanwhile, this gradual spacing setting, combined with the tilt angles of the mounting plate 51 and the guide plate 52, can further enhance the waterproof effect of the staggered structure. The cooling fan 40 on the mounting plate 51, due to its higher position and the outward expansion of the mounting plate 51, forms a more significant spatial misalignment with the air outlet 1112 below, effectively avoiding the risk of rainwater splashing upwards along the surface of the rear shell wall 111 to the fan during heavy rain. The inward trend of the guide plate 52 guides a small amount of rainwater that may enter the air guide shroud 50 to slide down along the surface of the guide plate 52 towards the bottom wall 113 and be discharged through the air outlet 1112, avoiding water accumulation that could affect equipment operation.

[0063] Reference Figure 7Optionally, multiple cooling fans 40 are provided to enhance heat dissipation efficiency. The mounting plate 51 has multiple air inlets 50A, with one cooling fan 40 located at each air inlet 50A. Specifically, the air inlets 50A are arranged in a regular pattern (such as a linear array or matrix distribution), and each air inlet 50A is equipped with an independent cooling fan 40, forming a layout where one fan corresponds to one air inlet 50A. This design can achieve multi-channel drive of airflow within the mounting cavity 10A by increasing the number of air inlets, allowing external cool air to be simultaneously introduced from different areas, effectively covering a wider range of heat-generating components such as the display module 30, and avoiding the heat dissipation blind spots that may exist with a single fan. The arrangement of multiple cooling fans 40 can also be differentiated according to the device's operating temperature. For example, under low load, only some fans operate to reduce energy consumption and noise, while under high load, all fans are activated at full power for rapid cooling, improving the flexibility and adaptability of the heat dissipation system. Meanwhile, the one-to-one correspondence between the air inlets 50A and the fans facilitates future maintenance and replacement. The failure or removal of a single fan will not affect the normal heat dissipation of other channels, ensuring the continuous and stable operation of the equipment. The layout of the multiple air inlets 50A on the mounting plate 51 can be reasonably distributed according to the size of the rear shell wall 111 of the housing 10. With the guiding effect of the guide plate 52, multiple airflows form a synergistic effect after entering the guide channel 10c, further enhancing the air convection efficiency and ensuring that the internal heat of the equipment can be discharged in a timely and even manner in high-temperature outdoor environments.

[0064] Reference Figure 7 Optionally, the air guide shroud 50 also includes a connecting plate 53. The mounting plate 51 and the guide plate 52 are respectively connected to opposite sides of the connecting plate 53, forming a stable triangular support structure to enhance the overall rigidity of the air guide shroud 50 to withstand the wind impact of complex outdoor environments. The connecting plate 53 can be fixed to the mounting plate 51 and the guide plate 52 by welding, screw connection, or other methods. For example, corresponding mounting holes can be opened at the junction of the three, and anti-loosening screws can be used to fasten them through to ensure that the structure does not loosen during long-term use.

[0065] Combined with reference Figure 4 and Figure 7The interactive all-in-one machine 100 also includes an adapter circuit board 60, which is connected to the side of the connecting plate 53 away from the rear housing wall 111 and is electrically connected to the cooling fan 40. The conductive contacts on the circuit board are electrically connected to the power cable of the cooling fan 40 via plug-in terminals or soldering. This layout design keeps the adapter circuit board 60 away from the heat-generating area inside the housing 10, and with the support of the connecting plate 53, the circuit components are integrated into the air guide shroud 50 structure, saving installation space and facilitating disassembly and maintenance later. Since the connecting plate 53 is located at the junction of the mounting plate 51 and the air guide plate 52, its outer side is protected by the inclined curved surface of the air guide plate 52, effectively reducing direct splashing of rainwater onto the circuit board surface. Combined with the waterproof coating on the circuit board surface, this further enhances the electrical safety of the equipment in humid environments.

[0066] Optionally, the edge of the air outlet 1112 near the bottom wall 113 is aligned with the edge of the guide plate 52 near the bottom wall 113. Thus, when rainwater or other liquids come into contact with the surface of the air guide shroud 50, the guide plate 52 acts as a catcher and guide, and thanks to the aligned edges, the water flow can smoothly slide along the surface of the guide plate 52 to the air outlet 1112. This seamless structure allows water to drain directly from the air outlet 1112 without obstruction under the influence of gravity, preventing water accumulation inside the air guide shroud 50, preventing rainwater from flowing back into the interactive all-in-one machine 100, protecting the equipment from water damage, and improving the safety and reliability of the equipment in humid, rainy, and other harsh environments.

[0067] Reference Figure 5 , Figure 6 as well as Figure 8 In some embodiments, the interactive all-in-one machine 100 further includes a support shell 70 and a filter component 80. The support shell 70 is connected to the rear shell wall 111 and covers the periphery of the air inlet 1111. The support shell 70 and the rear shell wall 111 enclose a partition cavity 10B that communicates with the air inlet 1111. The support shell 70 can be fixed to the rear shell wall 111 by means of screws or other methods. Specifically, multiple screw holes can be pre-set around the air inlet 1111 on the rear shell wall 111, and mounting holes can be opened at corresponding positions on the support shell 70. Screws are then passed through the mounting holes and tightened into the screw holes in sequence to achieve a stable installation. The support shell 70 covers the periphery of the air inlet 1111 and encloses the partition cavity 10B that communicates with the air inlet 1111 with the rear shell wall 111. External airflow first enters the partition cavity 10B and forms a buffer transition within the cavity.

[0068] The support shell 70 has an air outlet 71 that connects to the partition cavity 10B. The filter element 80 is connected to the side of the support shell 70 away from the rear shell wall 111 and covers the air outlet 71. This connection method naturally creates a misalignment between the filter element 80 and the air inlet 1111. Since the filter element 80 is not directly attached to the air inlet 1111, but rather attached to the support shell 70, its installation position is determined by the structure of the support shell 70. This non-attached installation makes the filter element 80 and the air inlet 1111 spatially offset. In this way, the external airflow must first enter the partition cavity 10B, and then pass through the filter element 80 after a tortuous path. This not only prolongs the contact time between the airflow and the filter material, improving the filtration efficiency, but also, due to the misaligned layout, prevents rainwater from directly impacting the filter element 80 along a straight trajectory. While ensuring good filtration effect, it significantly improves waterproof performance and ensures the long-term stable operation of the filter element 80.

[0069] Furthermore, the cross-section of the partition cavity 10B gradually decreases from the top wall 112 towards the bottom wall 113. This special structural design can constrain and guide the airflow entering the partition cavity 10B. When the external airflow enters the partition cavity 10B from the air outlet 71 of the support shell 70, the airflow will naturally accelerate as the space gradually narrows, forming a stronger flow trend. At the same time, this gradually narrowing space also makes the airflow distribution within the partition cavity 10B more uniform, avoiding local airflow turbulence and ensuring that the airflow can pass through the filter component 80 in an orderly and efficient manner, improving the overall ventilation efficiency and filtration effect. In addition, during rainy weather, the gradually decreasing cross-section of the partition cavity 10B can promote the rapid downward collection and discharge of rainwater, preventing rainwater from accumulating inside the cavity and further enhancing the waterproof performance of the equipment.

[0070] Furthermore, the edge of the air inlet 1111 near the bottom wall 113 is aligned with the bottom of the partition cavity 10B. This alignment plays an important role in dealing with rainwater intrusion. After rainwater enters the partition cavity 10B, it can be quickly discharged along the bottom of the partition cavity 10B by means of the alignment structure between the bottom of the cavity and the edge of the air inlet 1111, preventing rainwater from accumulating in the cavity and flowing back into the air inlet 1111, thus further enhancing the waterproof performance of the interactive all-in-one machine 100.

[0071] Reference Figure 5 and Figure 9Optionally, the housing 10 also includes two grille supports 13. The opposite ends of each grille support 13 are connected to the side of the display module 30 near the touchscreen 20 and the housing 11, respectively. At least a portion of one grille support 13 is located at the air inlet 50A of the second air duct 10b, and at least a portion of the other grille support 13 is located at the air outlet 1112 of the second air duct 10b. The grille supports 13 are made of durable metal, and their opposite ends are securely connected to the side of the display module 30 near the touchscreen 20 and the housing 11, forming a reliable support structure. The precise placement of at least a portion of one grille support 13 at the air inlet 50A of the second air duct 10b not only provides initial guidance and homogenization of the airflow entering the second air duct 10b, but also prevents larger external debris from entering the air duct, thus avoiding interference with normal airflow within the second air duct 10b. At least a portion of the other grille bracket 13 is located at the air outlet 1112 of the second air duct 10b. On the one hand, it helps to guide the airflow to be discharged smoothly and reduce wind resistance. On the other hand, it provides additional structural support for the air outlet 1112 area to prevent the outer casing 11 from being deformed or damaged due to external forces or airflow impact during long-term use. This ensures that the second air duct 10b can stably and efficiently perform its heat dissipation and ventilation functions, while also ensuring the integrity and reliability of the overall structure of the interactive all-in-one machine 100.

[0072] Reference Figure 4 and Figure 9 Optionally, the housing 10 also includes two air guide baffles 14. The two air guide baffles 14 are located between the side of the display module 30 facing the touch screen 20 and the housing 11, and together with the display module 30 and the touch screen 20, they form a second air duct 10b. The ends of the two air guide baffles 14 near the top wall 112 respectively define the outlet of the second air duct 10b with the display module 30 and the touch screen 20, and the ends of the two air guide baffles 14 near the bottom wall 113 respectively define the inlet of the second air duct 10b with the display module 30 and the touch screen 20.

[0073] Specifically, the two air guide baffles 14 are precisely positioned in space. At the end near the top wall 112, the air guide baffle 14, together with the display module 30 and the touch screen 20, defines the outlet of the second air duct 10b. This outlet position is carefully designed to effectively guide the smooth exhaust of airflow. At the end near the bottom wall 113, the air guide baffle 14 also collaborates with the display module 30 and the touch screen 20 to form the inlet of the second air duct 10b, providing a stable path for external air to enter. In this way, the second air duct 10b achieves a complete and smooth airflow channel. Air enters from the bottom inlet, carries away the heat generated by the display module 30 and other components within the duct, and then exits from the top outlet, greatly improving heat dissipation efficiency and ensuring that key components inside the equipment are always in a suitable operating temperature environment, effectively extending the equipment's service life and ensuring operational stability.
