Description

Technical Field

[0001] This utility model relates to the field of oxygenation controller technology, and in particular to an oxygenation controller with good waterproof performance. Background Technology

[0002] In aquaculture and other fields, oxygenation controllers are key equipment for ensuring stable dissolved oxygen levels in water. Their working environment is often harsh, with high water vapor and humidity.

[0003] Existing oxygenation controllers are inadequate in terms of waterproofing. The connection structure between the controller housing and the cover plate and other components is simple, making it difficult to achieve a reliable seal. Ordinary plug-in or screw connections are prone to water seepage due to gaps or installation errors, which can damage the internal controller body and affect the normal operation and service life of the equipment.

[0004] Therefore, we propose an oxygenation controller with good waterproof properties. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology. The existing oxygenation controller is not waterproof. The connection structure between the controller shell and the cover plate and other components is simple and it is difficult to achieve a reliable seal. Ordinary plug-in or screw connection methods are prone to water seepage due to gaps, installation errors, etc., which can damage the internal controller body and affect the normal operation and service life of the equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A waterproof oxygenation controller includes a controller housing, inside which is a controller body. A connection and positioning structure is provided on the controller housing. A sealing plug-in cover structure is provided at the connection point of the connection and positioning structure. The sealing plug-in cover structure is inserted into the connection and positioning structure to achieve positioning installation and multiple sealing protection functions. Waterproof heat dissipation structures are provided on both side walls of the controller housing. These structures are used to dissipate heat from the controller body while preventing moisture from entering the controller body.

[0008] As a preferred embodiment of this utility model, the connection positioning structure includes a plug-in sealing groove, a sealing gasket, a mounting cavity, a positioning mounting groove, a guide groove, and a guide inclined seat. The plug-in sealing groove is formed on the front side of the controller housing, and the sealing gasket is installed on the inner wall of the plug-in sealing groove.

[0009] As a preferred embodiment of this utility model, the mounting cavity is located at the center of the front side of the controller housing and is used to place the controller body. The positioning mounting groove is located on both side walls of the controller housing. The guide groove is located on the top of the controller housing. The guide sill is installed inside the guide groove.

[0010] As a preferred embodiment of this utility model, the sealing plug-in cover structure includes a cover body, a guide plug-in block, a sealing plug-in block, and a triangular guide seat. Two guide plug-in blocks are installed on the two side walls of the cover body near the top. Triangular guide seats are provided at the bottom of the two guide plug-in blocks and on the two side walls of the cover body. A sealing plug-in block is installed on the back side wall of the cover body.

[0011] As a preferred embodiment of this utility model, the cover plate body is inserted into the positioning and mounting groove by a guide plug-in block to form a guide positioning. The sealing plug-in block is inserted into the plug-in sealing groove and fits against the sealing gasket to form a seal. After the triangular guide seat is inserted, it covers the gaps at the connection points on both sides between the cover plate body and the controller housing and guides water to slide off.

[0012] As a preferred embodiment of this utility model, the top of the cover plate body is L-shaped and fits snugly against the top of the controller housing. The guide slant is used to guide water to slide down to both sides and to guide the guide plug block to slide to the outside, thereby achieving further waterproofing of the top connection.

[0013] As a preferred embodiment of this utility model, the waterproof heat dissipation structure includes a drainage channel, and waterproof oblique ventilation holes are symmetrically opened on both sides of the drainage channel. A drainage grid is also provided at the bottom of the drainage channel.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, a connection and positioning structure is provided on the controller housing. The plug-in sealing groove and the sealing gasket therein provide a basis for the sealing plug-in block in the sealing plug-in cover structure to fit and seal. When the sealing plug-in block is inserted into the plug-in sealing groove and fits tightly with the sealing gasket, the first effective sealing line is formed, which can greatly prevent external moisture from seeping in from the front connection.

[0016] The optimized cover plate connection design, with the guide plug-in block in the sealed plug-in cover plate structure inserted into the positioning mounting groove, not only guides and positions the cover plate body to ensure installation accuracy, but also further assists the sealing process, reducing gaps caused by installation position deviations. At the same time, after the triangular guide seat is plugged in, it can cover the gaps at both sides of the connection between the cover plate body and the controller housing, guiding water to slide off and preventing water from accumulating in the gaps and seeping into the interior. This strengthens the overall sealing performance from multiple angles, significantly improving the sealing performance of the connection between the entire controller housing and the cover plate.

[0017] The top is reinforced with waterproofing. The top of the cover plate is L-shaped and fits snugly against the top of the controller housing. Combined with the guide angle seat, water is guided to slide down to both sides and then to the guide plug block, finally sliding out to the outside. This design achieves further waterproofing at the top connection.

[0018] The waterproof and heat dissipation structure features symmetrical waterproof, angled vents on both sides of the drainage channel. These vents allow heat generated by the controller to exchange with the outside air for effective heat dissipation, while the angled design prevents external moisture from directly entering the device. Furthermore, the drainage grille at the bottom of the drainage channel does not obstruct airflow, ensuring minimal impact on heat dissipation efficiency. Even if a small amount of moisture accidentally enters the drainage channel, it can be promptly drained through the grille, preventing accumulation inside the device. This effectively dissipates heat from the controller while preventing moisture from entering. Attached Figure Description

[0031] Example

[0032] like Figure 1-7As shown, this utility model provides a technical solution: by carefully setting a connection and positioning structure on the controller housing 1, this structure encompasses several key components, among which the insertion sealing groove 101 plays a crucial role. It is precisely opened on the front of the controller housing 1, and its shape and size are designed according to the sealing insertion block 303 that subsequently mates with it, aiming to provide a fitting receiving space for sealing. The sealing gasket 102 is installed on the inner wall of the insertion sealing groove 101. The sealing gasket 102 is usually made of a material with good elasticity, water resistance, and sealing performance, such as rubber. When the sealing insertion block 303 in the sealing insertion cover structure is inserted into the insertion sealing groove 101, due to the sealing gasket... With the presence of 102, the sealing plug 303 will fit tightly against the sealing gasket 102. This fit is not a simple contact, but is based on the elastic deformation of the material. The sealing gasket 102 will undergo moderate deformation under the compression of the sealing plug 303, filling any tiny gaps that may exist between them, thus forming the first effective sealing barrier. This barrier can greatly prevent external moisture from seeping in from the front connection. Even in humid environments, such as the high humidity and water vapor around aquaculture ponds, or in rainy weather where water droplets splash onto the controller housing 1, this sealing structure can effectively prevent moisture from entering the interior along the front connection, thereby providing reliable protection for the controller body 2.

[0033] The principle lies in utilizing the elastic deformation characteristics of the sealing material (sealing gasket 102) and the tight fit of the sealing structure. When the sealing gasket 102 is squeezed by external force, it will deform accordingly according to the shape of the contact object and the pressure, so that the gap between the sealing surfaces is filled, thereby blocking the passage of water. At the same time, the shape matching design of the insertion sealing groove 101 and the sealing insertion block 303 ensures that the two can form a relatively closed space after installation, further enhancing the waterproof effect. This conforms to the basic physical principle of fluid sealing and prevents external water from entering the interior under the action of pressure difference, etc.

[0034] The optimized cover plate connection design is reflected in several aspects. First, the design of the guide plug-in block 302 in the sealed plug-in cover plate structure is inserted into the positioning mounting groove 104. The positioning mounting groove 104 is opened on both sides of the controller housing 1, and its position and size are precisely matched with the guide plug-in block 302. When the guide plug-in block 302 is inserted into the positioning mounting groove 104, it is like a mortise and tenon structure, realizing the precise guidance and positioning of the cover plate body 301. This guidance and positioning function not only ensures that the cover plate can be accurately placed in the predetermined position during the installation process, avoiding the installation position deviation caused by human operation and other factors, but also has important significance in terms of sealing, because the accurate installation position can ensure that the cover plate and the various connection parts of the controller housing 1 fit perfectly, reducing the gaps caused by inaccurate installation position.

[0035] Meanwhile, the triangular guide seat 304 plays a unique role after insertion. The triangular guide seat 304 is installed at the bottom of the guide plug block 302 and on both side walls of the cover body 301. Its shape is triangular with a certain tilt angle. After the cover is installed, the triangular guide seat 304 is exactly above the gap at the connection between the cover body 301 and the controller housing 1 on both sides. When water comes into contact with this part, the tilted surface of the triangular guide seat 304 will guide the water to slide down its surface, instead of allowing water to accumulate in the gap. This utilizes the physical property that water will flow along the tilted surface under the action of gravity, avoiding water from accumulating in the gap for a long time and seeping into the interior under the influence of capillary action or pressure difference. This strengthens the overall sealing performance from multiple angles, significantly improving the sealing performance of the connection between the entire controller housing 1 and the cover. Whether it is water vapor condensation that may be encountered in daily use or occasional splashing, this design can effectively ensure a dry internal environment and protect the controller body 2 from moisture damage.

[0036] The cooperation between the guide plug 302 and the positioning mounting groove 104 is based on the positioning principle in mechanical structure. The precise positioning is achieved through the fit of the shapes, ensuring the accuracy of installation and indirectly improving the sealing effect. The waterproof principle of the triangular guide seat 304 utilizes the gravity of water and the wettability of the object surface (i.e., the characteristic that water flows easily on inclined surfaces). Through reasonable shape design, the water flow direction is guided to prevent water from accumulating in key parts, thereby reducing the possibility of water seepage and comprehensively improving the overall sealing performance, which is in line with the relevant principles of fluid mechanics and surface physics.

[0037] The top waterproof reinforcement is another important design highlight of this utility model. The top of the cover plate body 301 is L-shaped. This unique shape design forms a clever mutual fit with the top of the controller housing 1. Part of the top of the L-shaped cover plate covers the outer side of the top of the controller housing 1, while the other part fits into its inner side, just like a lid tightly covering it, protecting the top connection from both the top and bottom.

[0038] Furthermore, the design of the guide seat 106 guides water to slide down to both sides and then to the guide plug 302, finally sliding out to the outside. The guide seat 106 is installed inside the guide groove 105 on the top of the controller housing 1. The guide groove 105 provides a stable installation base for the guide seat 106. The guide seat 106 itself has a certain tilt angle and a suitable slope shape. When rainwater or water vapor accumulates on the top of the controller housing 1, the water will flow along the slope of the guide seat 106 under the action of gravity. Due to the guiding effect of the guide seat 106, the water will be guided to both sides and continue to slide down along the guide plug 302 on both sides, and finally discharged into the external environment. This layered guiding design fully considers the flow law of water on the surface of the object. Even if it is subjected to rain for a long time or water is easy to accumulate on the top in a high humidity environment, it can ensure that water will not seep into the controller from the top connection, realizing further waterproofing of the top connection, and comprehensively ensuring the dryness and safety of the controller inside, creating good conditions for the stable operation of the controller body 2.

[0039] The L-shaped design at the top of the cover body 301 utilizes a covering and fitting method to increase the contact area and protective layer at the top connection, structurally preventing water from entering. The waterproof principle of the guide seat 106 is also based on the characteristic of water flowing along an inclined surface under the action of gravity. By reasonably setting the tilt angle and position of the guide seat 106, the flow path of water is changed, causing it to move away from the inside of the controller, and guiding any water that may enter out, following the basic principles of water flow guidance and control in fluid mechanics.

[0040] The waterproof heat dissipation structure features symmetrical waterproof slanted vents 402 on both sides of the drainage channel 401. This design is quite ingenious. The drainage channel 401 itself is a groove-shaped structure located on both sides of the controller housing 1, providing a basic space guarantee for the entire heat dissipation and waterproofing process. The slanted vents 402 on both sides of the drainage channel 401 have carefully considered inclination angles, generally slanting downwards and outwards. The size of the vents is determined based on the airflow required for heat dissipation of the controller body 2 and the waterproofing requirements. It is necessary to ensure that the heat generated by the controller body 2 during operation can be fully exchanged with the outside air through these vents to achieve effective heat dissipation, while preventing external moisture from directly entering the interior through the vents.

[0041] When the controller body 2 is working, it generates heat, and the internal air temperature rises. The hot air exchanges heat with the relatively cooler outside air through these waterproof angled vents 402. The heat is dissipated with the air flow, thereby achieving the purpose of heat dissipation. Due to the waterproof angled design of the vents, external moisture, such as raindrops and water vapor, is difficult to enter the interior against the angle of the vents when affected by factors such as gravity and surface tension. Even if a small amount of moisture comes into contact with the outside of the vents, it will slide down along the angle of the vents under the action of gravity and cannot enter the interior of the controller.

[0042] Furthermore, the drainage grille 403 installed at the bottom of the drainage trough 401 is typically composed of strips or mesh structures with a certain spacing. Its material has good corrosion resistance and strength. On the one hand, the presence of the drainage grille 403 does not affect the normal airflow within the drainage trough 401. Hot air can still smoothly exchange with the outside air through the vents and the drainage trough 401, ensuring that the heat dissipation efficiency is not greatly affected. On the other hand, even in some special circumstances, such as a small amount of moisture accidentally entering the drainage trough 401, or water droplets condensing inside the drainage trough 401 due to water vapor carried by strong winds, these water droplets can be discharged in time through the gaps in the drainage grille 403, preventing them from accumulating inside the equipment. This avoids the potential risk of moisture damage to the controller body 2. It truly achieves the goal of effectively preventing moisture from entering the controller body 2 while dissipating heat, enabling the controller to maintain good working condition under various complex environmental conditions and ensuring the stable operation of aeration equipment in aquaculture and other related application scenarios.

[0043] The heat dissipation principle of the waterproof slanted vent 402 is based on the principle of heat exchange, using the flow of air to remove heat and achieve temperature regulation. Its waterproof principle relies on gravity, surface tension, and the slant angle of the vent, making it difficult for water to enter against the slant direction. This conforms to the fluid mechanics principles regarding the flow of liquids on slanted surfaces and the permeability characteristics of gases and liquids under different conditions. The working principle of the drainage grille 403 lies in its suitable gap structure, which neither obstructs airflow nor hinders the smooth passage of liquids under gravity, thus achieving the drainage function. This ensures both heat dissipation and waterproofing effects, comprehensively utilizing knowledge of fluid mechanics and thermodynamics.

[0044] Work process summary

[0045] Installation preparation: First, ensure that all parts of the controller housing 1 are structurally intact, that the sealing gasket 102 is correctly installed in the plug-in sealing groove 101 of the connection positioning structure, and that there are no blockages or other abnormalities on the waterproof vent holes 402 on both sides of the drainage groove 401 of the waterproof heat dissipation structure and the drainage grille 403 at the bottom. All components of the sealing plug-in cover structure (cover body 301, guide plug-in block 302, sealing plug-in block 303, triangular guide seat 304) are also ready.

[0046] Cover plate installation: Pick up the cover plate body 301, align the guide plug-in blocks 302 on its two side walls with the positioning mounting grooves 104 on the two side walls of the controller housing 1, and then slowly insert it. During the insertion process, the guide plug-in blocks 302 slide along the positioning mounting grooves 104 to guide and position the cover plate body 301, ensuring its accurate placement. When the cover plate body 301 basically covers the front of the controller housing 1, continue to press so that the sealing plug-in blocks 303 on the back side wall of the cover plate body 301 are inserted into the plug-in sealing grooves 101 on the front of the controller housing 1. At this time, the sealing plug-in blocks 303 and the sealing gaskets 102 are tightly fitted to form the first line of sealing defense. At the same time, the triangular guide seats 304 on the two side walls of the cover plate body 301 will cover the gaps at the connection points on both sides between the cover plate body 301 and the controller housing 1, completing the installation of the cover plate and enhancing the overall sealing performance.

[0047] Top waterproofing confirmation: Observe whether the L-shaped part of the top of the cover plate body 301 fits tightly with the top of the controller housing 1, confirm that the guide slant seat 106 is in the correct position and can guide water to slide down to the guide plug blocks 302 on both sides, ensuring that the top waterproofing function is normal.

[0048] Equipment operation and heat dissipation waterproof protection: During normal operation of the oxygenation controller, the heat generated by the controller body 2 will raise the internal air temperature. The hot air exchanges heat with the outside air through the waterproof inclined vents 402 on both sides of the drainage channel 401 in the waterproof heat dissipation structure, thus achieving heat dissipation. External moisture, such as rainwater and water vapor, will be blocked from the front by the sealing structure when it comes into contact with the controller housing 1. The moisture at the top will be guided to the sides by the guide inclined seat 106 and discharged. Even if a small amount of moisture comes into contact with the waterproof inclined vents 402 on the side, it will be difficult to enter the interior. If moisture enters the drainage channel 401, it can be discharged in time through the drainage grille 403. This comprehensive protection ensures that the equipment dissipates heat while preventing moisture from entering the controller body 2, ensuring stable operation of the equipment.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
