Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0024] like Figures 1-5 As shown, a waterproof alarm control box according to this application includes a box body 1, a box door 2, a heat dissipation and ventilation hole 3, a waterproof seal 4, a mounting bracket 5, and a lock 6.
[0025] Enclosure 1 forms the housing space to protect and enclose the internal electronic components. Enclosure 1 is typically made of corrosion-resistant metal materials (such as stainless steel or aluminum alloy) and assembled into a rectangular or cubic structure by welding or bolting 321, ensuring overall rigidity and sealing. The mounting location is on the base frame of the entire control box; for example, during manufacturing, bending and welding processes are used to construct the sheet metal into a closed shell, with the internal space designed to accommodate alarm controllers, circuit boards, and other equipment, thus providing physical protection and environmental isolation.
[0026] The door 2 is hinged to the enclosure 1, serving to close the enclosure 1 and provide access to the internal components. The door 2 is typically made of the same material as the enclosure 1 and opens and closes via a hinge mechanism (such as stainless steel hinges). The connection is a fixed installation, ensuring the door can rotate 90 to 180 degrees. For example, in practice, the hinge is secured to the front edge of the enclosure 1 by bolts 321, and the door edge is reinforced with ribs to enhance structural strength, facilitating quick opening and closing for user maintenance.
[0027] A heat dissipation ventilation hole 3 is located on the housing 1 to promote air circulation for heat dissipation while preventing water intrusion. This ventilation hole 3 includes multiple angled louvers 31, a water-blocking shield 32, and a ventilation opening 33. The multiple angled louvers 31 are located on the upper side wall of the housing 1, and their structure consists of continuously arranged blades with an angle of 30 to 60 degrees, allowing airflow while blocking splashing water. The water-blocking shield 32 is fixed to the housing 1, located above the heat dissipation ventilation hole 3, and adopts an arc-shaped or flat design to prevent rainwater from directly entering. The ventilation opening 33 has a downward-sloping trapezoidal cross-section to facilitate water droplet drainage. For example, in manufacturing, the angled louvers 31 are formed on the side wall of the housing 1 by stamping, the water-blocking shield 32 is fixed by welding or screws, and the trapezoidal cross-section is formed by injection molding, optimizing heat dissipation efficiency through overall layout.
[0028] A waterproof seal 4 is installed at the joint between the door 2 and the body 1 to provide a waterproof seal. This seal is typically made of an elastic material (such as rubber or silicone) and has a continuous strip or O-ring structure. It is installed within a groove on the edge of the door 2, achieving a tight fit through compression deformation. The connection method is either a snap-fit or adhesive fixation. For example, during assembly, the seal is pre-placed in the door frame groove. When the door 2 is closed, the seal expands under pressure, effectively preventing external moisture and dust from entering.
[0029] Mounting bracket 5 is fixed to the inner wall of enclosure 1 to support internal components (such as alarm modules or power supply units). This bracket is typically stamped from sheet metal (such as galvanized steel) and includes multiple mounting holes and support arms. It is installed by welding or bolting 321 to the rear or side wall of enclosure 1. For example, in practice, the bracket is designed to be adjustable, with screw holes to accommodate electronic components of different sizes, ensuring stable installation and easy maintenance and replacement.
[0030] Lock 6 is installed on the door 2 to lock the door and prevent unauthorized access. This lock 6 is typically a mechanical or electronic lock, consisting of a lock cylinder, bolt, and keyhole. It is fixed to the center of the outer side of the door 2 by screws or an embedded method. The connection is a direct fastening; for example, during manufacturing, the base of lock 6 is welded to the door panel, and the bolt engages with a retaining ring on the cabinet 1. When the key is turned, the bolt extends to achieve the locking function, enhancing equipment security.
[0031] The aforementioned features solve the technical problem of how to arrange the location and shape of the ventilation holes 3 in the enclosure 1 to balance heat dissipation requirements and splash protection. Specifically, the ventilation holes 3 achieve this goal through a multi-level protection design: First, multiple slanted louvers 31 are installed on the upper part of the side wall of the enclosure 1, with an inclination angle of 30 to 60 degrees, allowing natural air convection for heat dissipation while physically blocking splash water from entering; second, a water-blocking cover 32 is fixed above the ventilation holes, forming a physical barrier to effectively block direct rainwater; finally, the ventilation hole openings 33 adopt a downward-sloping trapezoidal cross-section, guiding water droplets to quickly drain along the slope and preventing water accumulation. This layout combines location optimization (avoiding direct exposure on the upper part of the side wall) and shape design (slanted and trapezoidal structure). Technically, stamping and molding processes ensure a balance between efficient heat dissipation and waterproofing. For example, in outdoor environments, air can circulate smoothly to cool internal electronic equipment, while splash water or rainwater is blocked and drained through multiple layers, thus balancing heat dissipation performance and waterproof reliability.
[0032] like Figure 1 and Figure 3 As shown, in one embodiment, the heat dissipation vents 3 are configured in the lower region of the side wall of the enclosure 1, specifically at the lower end of the side wall of the enclosure 1. This arrangement helps to reduce the impact of external splashing water by lowering the height of the vents, as the lower region is generally less exposed to direct rain splashes. Furthermore, the heat dissipation vents 3 are symmetrically distributed on the left and right side walls of the enclosure 1, ensuring a balanced ventilation path on both sides of the enclosure 1. This symmetrical distribution promotes uniform heat dissipation, avoids localized overheating, and enhances airflow efficiency through the dual-sided arrangement, further improving heat dissipation performance. The choice of location, combined with symmetry, optimizes waterproofing and reduces the risk of water intrusion.
[0033] Specifically, the heat dissipation ventilation holes 3 include multiple inclined louvers 31, which are disposed on the lower part of the side wall of the housing 1 and inclined at an angle of 30 to 60 degrees to allow airflow while blocking splashing water; a water-blocking cover 32 is fixed to the housing 1 and located above the heat dissipation ventilation holes 3 to shield against rainwater; and the ventilation hole opening 33 has a downwardly inclined trapezoidal cross section to facilitate the discharge of water droplets. Specifically, the heat dissipation ventilation holes 3 are symmetrically distributed on the left and right side walls of the housing 1, for example, by installing the louvers and cover assemblies at corresponding positions on both sides of the housing 1 to ensure structural consistency and uniform heat dissipation.
[0034] For example, slanted louvers 31 are installed on the upper side wall of the housing 1, with an inclination angle between 30 and 60 degrees. This design allows airflow to pass smoothly through the interior of the housing 1 while effectively preventing external splashing water from entering. The louvers extend outward and downward in an outward and downward direction, forming a continuously arranged blade structure. Each blade is made of thin sheet material and is fixed to the wall of the housing 1, achieving permanent installation through welding or riveting. This layout ensures that water droplets cannot directly enter the internal space during heat dissipation.
[0035] like Figure 2 and Figure 3 As shown, in one embodiment, there are 10 angled louvers 31, and the spacing between adjacent louvers is 15 mm. This spacing is optimized to ensure a uniform distribution of airflow channels, avoid airflow blockage, and minimize the penetration path of water droplets. The louvers are arranged based on a linear array structure, with all blades arranged in parallel and at consistent spacing to balance heat dissipation efficiency and waterproof performance.
[0036] Specifically, the oblique louvers 31 are formed by a stamping process. Ten equidistant holes are pre-positioned on the upper side wall of the housing 1, and then the oblique blades are formed by pressing with a mold. Specifically, the spacing between each blade is precisely controlled at 15 mm, and a fixing fixture is used to ensure that the adjacent blades maintain a uniform interval.
[0037] like Figure 3 As shown, in one embodiment, the water-retaining shield 32 is designed with an arc-shaped structure. This arc-shaped profile helps guide rainwater to slide down the curved surface, preventing water accumulation or direct seepage into the interior. Specifically, the width of the water-retaining shield 32 is set to be greater than the width of the ventilation opening 33, thereby providing more adequate coverage in the horizontal direction and ensuring that rainwater is effectively blocked. For example, the arc-shaped structure may extend to the outer edges on both sides of the ventilation opening 33, forming additional protective areas to cope with rainfall at different angles.
[0038] Specifically, the arc-shaped structure and width relationship of the water-retaining cover 32 are achieved through precise dimensional matching, wherein the ratio of the arc curvature radius to the opening width is calculated and optimized to maximize the shielding efficiency. Specifically, the water-retaining cover 32 is manufactured using a one-piece molding process, and its width exceeds the lateral dimension of the ventilation opening 33, ensuring that the space above the opening is completely covered after installation.
[0039] For example, the water-retaining shield 32 is connected to the top of the housing 1 by fasteners and is located directly above the heat dissipation and ventilation holes 3. The water-retaining shield 32 is molded into an arc shape from weather-resistant plastic, and its width extends beyond the two sides of the ventilation hole opening 33. The specific connection method includes bolts 321 fastening it to the surface of the housing 1 to ensure that the structure is stable and the coverage area fully covers the ventilation hole opening 33 area.
[0040] like Figure 1 and Figure 2 As shown, in one embodiment, a water-retaining cover 32 is disposed on the housing 1 and located above the heat dissipation and ventilation holes 3 to effectively block rainwater and external splashes, thereby protecting the internal components from moisture intrusion. Specifically, the cover is fixedly connected by mechanical fasteners to ensure its stability and reliability in harsh environments. For example, bolts 321 are used as fastening elements, allowing the cover to be detachably installed on the surface of the housing 1 for easy subsequent maintenance operations.
[0041] Specifically, the water-blocking cover 32 is directly fixed to the top of the outer wall of the box 1 by bolts 321. Specifically, the bolts 321 pass through the mounting holes of the cover and are screwed into the pre-set threaded holes of the box 1 to form a firm connection, while allowing disassembly and reassembly with simple tools.
[0042] like Figure 3 As shown, in one embodiment, the heat dissipation ventilation hole 3 of a waterproof alarm control box of this application further includes a filter screen 34, which is disposed inside the ventilation hole opening 33 to prevent dust from entering while maintaining unobstructed airflow. Specifically, the filter screen 34 is located in the internal area of the ventilation hole opening 33, adjacent to the inlet end of the opening, to form a physical barrier, thereby effectively intercepting external dust particles without obstructing the airflow path. This positioning design ensures that the filter screen 34 does not interfere with the overall waterproof function of the heat dissipation ventilation hole 3, such as the function of the angled louvers 31 and the water-blocking cover 32, while maintaining the continuity of the airflow channel.
[0043] Specifically, the filter screen 34 is typically constructed from a porous mesh material, such as wire mesh or synthetic fiber mesh, with its mesh size configured to allow air to pass freely while blocking fine dust. The filter screen 34 is fixedly attached to the inner wall of the ventilation opening 33 using methods such as clips, screws, or adhesive, ensuring its secure fit and ease of maintenance. Specifically, the edges of the filter screen 34 directly contact the inner wall of the opening, forming a sealing fit to prevent dust from seeping in through gaps while maintaining the overall structural compactness.
[0044] For example, the filter screen 34 is made of stainless steel wire mesh, and its edges are fixed to the inner wall groove of the ventilation hole opening 33 by a snap-fit structure, thereby ensuring that the mesh surface is flat and fits well, while facilitating disassembly and cleaning to maintain long-term dustproof effect.
[0045] like Figure 5As shown, in one embodiment, regarding the arrangement of the waterproof seal 4, the seal is disposed at the joint area between the door 2 and the body 1, which corresponds to the boundary portion where the door 2 contacts the body 1 when closed, to ensure the formation of an effective waterproof barrier in the closed state. Specifically, the joint includes the edge portion of the door 2 and the corresponding frame surface of the body 1, and the seal is positioned to cover the entire contact surface to prevent external moisture from seeping into the internal containment space of the control box through the gap.
[0046] Specifically, the waterproof seal 4 is constructed of rubber, which possesses inherent elasticity and flexibility, allowing it to compress and deform when the door 2 is closed. This compression deformation ensures the seal fits tightly against the surfaces of the door 2 and the enclosure 1, forming a uniform sealing layer. The rubber material was chosen based on its weather resistance and anti-aging properties, making it suitable for long-term waterproofing needs in outdoor environments.
[0047] Specifically, the waterproof seal 4 is fixed to the inner edge of the door 2 via a slot structure. For example, the edge of the door 2 has a continuous groove, and the rubber seal is pressed into and embedded in the groove, thereby ensuring that the seal is stably attached and surrounds the joint. Specifically, the rubber seal is made by compression molding, and its cross-section is rectangular or trapezoidal to optimize the sealing performance during compression. Moreover, no additional fasteners are required during installation, simplifying the assembly process.
[0048] like Figure 3 As shown, in one embodiment, the mounting bracket 5 is slidably fixed to the inner wall of the housing 1 to optimize space layout and maintain heat dissipation performance. Specifically, the mounting bracket 5 is connected to the inner wall surface of the housing 1 via a sliding mechanism, allowing it to move in a predetermined direction, thereby flexibly adjusting its position when installing internal components. This design ensures that the mounting bracket 5 does not permanently occupy a specific area, avoiding interference with the normal airflow path of the heat dissipation vents 3.
[0049] Specifically, the sliding fixation involves the connection between the mounting bracket 5 and the inner wall of the housing 1, including guide rails or sliding groove assemblies, which are integrated between the bracket base and the wall of the housing 1. The sliding stroke of the mounting bracket 5 is limited within a specified range on the inner wall of the housing 1 to prevent excessive movement that could affect other components. Furthermore, the sliding mechanism includes a locking device to fix the bracket position when needed, ensuring support stability.
[0050] For example, the slide rail extends parallel to the side wall of the housing 1, and the bottom of the mounting bracket 5 is embedded in the slide groove, allowing the bracket to slide horizontally; specifically, when adjusting the position of the bracket, the area of the heat dissipation and ventilation hole 3 can be avoided, ensuring that the airflow of the inclined louvers 31 and the ventilation hole opening 33 is not obstructed.
[0051] like Figure 1 and Figure 2As shown, in one embodiment, the lock 6 is equipped with a waterproof cover 61 that directly covers the operating portion of the lock 6 to prevent rainwater from seeping into the internal components. Specifically, the operating portion typically includes a keyhole or key insertion area located on the exposed surface of the lock 6. The waterproof cover 61 forms a physical barrier by covering this area, thereby preventing external moisture from entering. The waterproof cover 61 is installed close to the operating interface of the lock 6 to ensure a sealed state when not in operation.
[0052] Specifically, the waterproof cover 61 can be designed as a movable component, for example, connected to the lock body 6 via a hinge or pivot, allowing the user to open the waterproof cover 61 to access the operating parts and reset it after operation to restore its waterproof function. The waterproof cover 61 can be made of elastic or rigid materials to enhance its durability and sealing performance, while its shape matches the operating parts of the lock 6 to prevent moisture penetration due to gaps.
[0053] For example, the waterproof cover 61 is pivotally connected and fixed to the lock housing 6, covering the keyhole area. Specifically, the waterproof cover 61 can be designed with a resilient sealing ring. When the user rotates the waterproof cover 61 to expose the keyhole for operation, the user can manually reset the waterproof cover 61 after operation, ensuring it fits tightly against the lock housing 6, forming a waterproof barrier. For example, the pivot connection point of the waterproof cover 61 is located on the side of the lock body 6, ensuring its stability during opening and closing, thereby effectively preventing rainwater from seeping into the operating parts.
[0054] like Figure 4 As shown, in one embodiment, the bottom of the waterproof alarm control box 1 of this application is provided with a drain hole 11. The drain hole 11 is located at the lowest point of the box 1 to effectively drain any small amount of water that may seep in under the influence of gravity. Specifically, as part of the overall waterproof design, the drain hole 11 is installed in the center or edge area of the bottom plate of the box 1 to ensure that water can flow naturally and drain out, preventing internal components from getting damp. This feature works in conjunction with the heat dissipation ventilation holes 3 on the box 1, which are located on the upper part of the side wall of the box 1 and have a waterproof structure. The drain hole 11 treats residual water at the bottom, thereby optimizing the overall waterproof performance. For example, when a small amount of water splashes in through the heat dissipation ventilation holes 3, the water will accumulate at the bottom of the box 1, and the drain hole 11 will drain it in time to prevent long-term retention from affecting the internal circuitry.
[0055] Specifically, the drainage hole 11 is technically implemented by machining a circular or rectangular opening on the bottom plate of the housing 1. The opening is designed with a small diameter to limit the entry of large particles of impurities, while a mesh filter structure can be installed inside to prevent clogging. Specifically, the drainage hole 11 is integrally formed with the housing 1 or fixed by welding to ensure airtightness, and together with the angled louvers 31 of the heat dissipation ventilation hole 3 and the water-blocking cover 32, it forms a coordinated waterproof system.
[0056] In actual operation, when this device is in use, the user can access the internal space of the control box by opening the box door 2. The internal components are supported by the mounting bracket 5 to maintain stability. After closing the box door 2, the lock 6 is used to lock the box door 2 to ensure safety. At the same time, the waterproof seal 4 forms a seal at the joint between the box door 2 and the box body 1 to prevent water from seeping in. During the operation of the control box, the heat generated by the internal components is dissipated through the heat dissipation ventilation holes 3. Air flows through multiple inclined louvers 31 into the box body 1. The inclined angle of the inclined louvers 31 blocks splashing water. The water-blocking cover 32 is located above the heat dissipation ventilation holes 3 to shield rainwater. The downward inclined trapezoidal section of the ventilation hole opening 33 promotes the discharge of water droplets, thereby achieving heat dissipation and waterproofing functions.
