Description

Technical Field

[0001] This utility model belongs to the technical field of waterproof structure for medical device products, specifically relating to a double louver waterproof structure for a box body. Background Technology

[0002] Pneumatic products are medical devices that operate under high loads for extended periods. They typically utilize an air pump to draw air from an air tank at appropriate pressure, controlling the intake and shut-off of airflow by opening or closing a solenoid valve, with the air pressure controlled by a main control module. High temperatures are unavoidable during operation, requiring adequate ventilation and heat dissipation. Excessive heat can damage the air pump and accelerate the aging of internal components, severely impacting their lifespan.

[0003] In the current technology, achieving both good ventilation and heat dissipation efficiency and precise waterproofing in the enclosure of medical devices is an urgent problem to be solved in the industry. At present, most medical products on the market achieve ventilation and heat dissipation by setting raceway holes or dense holes in the enclosure. Ordinary raceway holes or dense holes have certain drawbacks in use. They are not waterproof, which makes the internal components of the device easy to be damaged. They also make the internal components of the device easy to see, which not only affects the aesthetics but also does not meet the product safety regulations (EMC) requirements. This situation needs to be further improved.

[0004] The previously disclosed patent CN211406505U, a waterproof structure for louvers, mentions waterproofing of louvers. It describes a baffle plate installed on the inner wall of the unit at the louver opening. This structure improves waterproofing to some extent (reducing the risk of water ingress), but it doesn't completely solve the waterproofing problem and has poor ventilation and heat dissipation, thus affecting the product's functional stability. Another example is patent CN209017371U, a waterproof structure for louvers used in outdoor enclosures. It also mentions waterproofing of louvers, but it involves welding a waterproof cover to the inside of the louvers. This structure requires full welding for waterproofing. Since the louver area is large, full welding inevitably causes significant deformation and rust, severely affecting the product's appearance. Conventional processes use spot welding or segmented welding, but spot welding does not achieve complete waterproofing. Utility Model Content

[0005] The purpose of this utility model is to overcome the existing technical defects and provide a double louver waterproof structure for box bodies, which has the characteristics of good waterproof and unsightly covering effect, low manufacturing cost and good ventilation and heat dissipation effect.

[0006] To solve the above-mentioned technical problems, this utility model provides a double-louvered waterproof structure for a box body. At least one first louver with a downward opening is provided on at least one side of the box body. A first air inlet / outlet duct is formed between each first louver and the box body. A waterproof plate is detachably provided inside the box body on the inner side of the first louver. A second louver with an upward opening is provided on the waterproof plate at the position corresponding to each first louver. A second air inlet / outlet duct is formed between each second louver and the waterproof plate. The second air inlet / outlet duct is connected to the first air inlet / outlet duct in a one-to-one correspondence.

[0007] Furthermore, the lower ends of the first air inlet / outlet duct are aligned with the lower ends of the second air inlet / outlet duct, and the upper ends of the first air inlet / outlet duct are aligned with the upper ends of the second air inlet / outlet duct, so that the first air inlet / outlet duct and the second air inlet / outlet duct are connected to form an inclined air inlet / outlet channel, and the outer opening of the air inlet / outlet channel is set downwards, and the inner opening of the air inlet / outlet channel is set upwards.

[0008] Furthermore, the box body is characterized by having at least one downward-facing first louver on each side, and a waterproof plate covering all the first louvers on the corresponding side inner walls of the box body.

[0009] Furthermore, the first louvers on both sides of the box are symmetrically arranged.

[0010] Furthermore, the first louvers on both sides of the box are arranged in an array, and the second louvers are arranged in an array on the waterproof plate and correspond one-to-one with the first louvers.

[0011] Furthermore, multiple studs are provided on both inner walls of the box body, and multiple through holes are provided on the waterproof plate for the studs to pass through one by one. Matching nuts are provided on the studs to fix the waterproof plate to the studs.

[0012] Furthermore, the studs are fixed to the inner walls of both sides of the housing by welding.

[0013] Furthermore, the waterproof membrane is fixed to the inside of the box body with screws.

[0014] Furthermore, a waterproof sealant ring is provided between the perimeter of the waterproof membrane and the inner wall of the box.

[0015] Furthermore, the waterproof adhesive is an organosilicon sealant.

[0016] This utility model has the following beneficial effects:

[0017] In this invention, a first louver with a downward-facing opening is provided on the outer side of the housing, and a detachable waterproof plate is provided on the inner side of the housing. The waterproof plate also has a second louver with an upward-facing opening at the corresponding position of each first louver. This structure of upward-facing and downward-facing louvers provides the housing with excellent waterproofing and concealing properties, low manufacturing cost, and good ventilation and heat dissipation, while also meeting EMC safety regulations. The waterproof plate is fixed in a detachable manner, which avoids deformation and rusting issues compared to existing technologies that require full welding to fix the waterproof cover. Furthermore, this application uses a direct connection between the second and first air inlets / outlets, which, compared to existing technologies where the openings between the inner and outer louvers need to be connected through the internal space of the waterproof cover, provides better ventilation and heat dissipation and a simpler structure.

[0018] Secondly, the waterproof membrane is fixed inside the box by studs and nuts, which has the characteristics of simple structure and convenient installation. The studs can be directly fixed to the inner wall of the box by welding, which is simple to manufacture and avoids the problem of indentation affecting the appearance of the product when fixing the waterproof membrane by riveting. In addition, the welding area is small, which further avoids the problem of deformation and rust of the box.

[0019] In addition, a ring of waterproof adhesive is applied between the waterproof membrane and the inner wall of the box to further improve the waterproof performance, achieve the purpose of precise waterproofing, improve the stability and reliability of the product during use, and the process of applying the waterproof adhesive is relatively simple and does not affect the appearance of the product at all, ensuring the aesthetics of the box.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] like Figures 1 to 3 As shown in this embodiment, a double-louvered waterproof structure for a housing is provided. This housing can be used as the outer shell of an extracorporeal shock wave therapy device. Several downward-facing first louvers 10 are provided on both the left and right sides of the housing 1. Each first louver 10 forms a first air inlet / outlet duct 11 with the housing 1, thereby achieving airflow between the inside and outside of the housing 1 through the first air inlet / outlet duct 11, achieving ventilation and heat dissipation. The downward-facing openings of the first louvers 10 effectively prevent external rainwater from entering the housing 1 through the first air inlet / outlet duct 11. The sides of the housing 1... A waterproof plate 2 is detachably installed on the inner wall. The waterproof plates 2 on both sides cover all the first louvers 10 on the corresponding sides. That is, all the first louvers 10 on both sides are within the range of the waterproof plate 2. The waterproof plate 2 has a second louver 20 with its opening facing upward at the position corresponding to each first louver 10. That is, the position of the second louver 20 corresponds to the position of the first louver 10 on the inner and outer sides of the box. A second air inlet / outlet duct 21 is formed between each second louver 20 and the waterproof plate 2. The second air inlet / outlet duct 21 is connected to the first air inlet / outlet duct 11 in a corresponding manner.

[0029] In the above-described configuration, a first louver with a downward-facing opening is provided on the outer side of the enclosure, and a removable waterproof panel is provided on the inner side of the enclosure. The waterproof panel also has a second louver with an upward-facing opening at the corresponding position of each first louver. This structure of upward-facing and downward-facing louvers provides the enclosure with excellent waterproofing and concealing properties, low manufacturing cost, and good ventilation and heat dissipation, while also meeting EMC safety regulations. The waterproof panel is fixed in a removable manner, which avoids deformation and rusting issues compared to existing technologies that require full welding to fix the waterproof cover. Furthermore, the second air inlet / outlet duct is directly connected to the first air inlet / outlet duct in a one-to-one correspondence, resulting in better ventilation and heat dissipation and a simpler structure compared to existing technologies where the openings between the inner and outer louvers need to be connected through the internal space of the waterproof cover.

[0030] In one embodiment, such as Figure 3 As shown, the lower ends of the corresponding first air inlet / outlet duct 11 are aligned with the lower ends of the corresponding second air inlet / outlet duct 21, and the upper ends of the corresponding first air inlet / outlet duct 11 are aligned with the upper ends of the corresponding second air inlet / outlet duct 21, so that the two form a centrally symmetrical structure. After the first air inlet / outlet duct 11 and the second air inlet / outlet duct 21 are connected, they form an inclined air inlet / outlet channel, with the outer opening of the air inlet / outlet channel facing downwards and the inner opening of the air inlet / outlet channel facing upwards. Here, the inclined air inlet / outlet channel can further prevent external water from entering the box and from obstructing the view, thus improving the waterproof performance and the concealing effect, without affecting the ventilation and heat dissipation performance.

[0031] In one embodiment, such as Figures 1 to 3 As shown, the first louvers 10 on both sides of the box body 1 are arranged in an array, and the second louvers 20 are arranged in an array on the waterproof plate 2 and correspond one-to-one with the first louvers 10, thereby improving the overall aesthetics of the box body; preferably, the first louvers 10 on both sides of the box body 1 are arranged symmetrically from left to right, and the corresponding second louvers 20 on both sides are also arranged symmetrically from left to right.

[0032] In one embodiment, such as Figures 1 to 3 As shown, four studs 12 are provided on the inner walls of both sides of the housing 1. The four studs 12 are distributed on the four outer corners of all the first louvers 10 on one side. Each of the four corners of the waterproof plate 2 is provided with a through hole (not shown in the figure) for the studs 12 to pass through one by one. The studs 12 are provided with matching nuts 13. After the waterproof plate 2 is installed on the studs 12, it is locked and fixed on the outside by the nuts 13 to fix the waterproof plate 2 on the studs 12.

[0033] As a preferred option, such as Figures 1 to 3As shown, the studs 12 are fixed to the inner walls of both sides of the housing 1 by welding. During the production of the housing 1, four studs 12 for fixing the waterproof plate 2 can be pre-welded to the inner walls of both sides. The waterproof plate is fixed inside the housing by the cooperation of the studs and nuts. It has the characteristics of simple structure and convenient installation. The studs are directly fixed to the inner wall of the housing by welding, which is simple to manufacture and avoids the problem of the product appearance being affected by the presence of indentations when fixing the waterproof plate by riveting. In addition, the welding area is small, which further avoids the problem of deformation and rusting of the housing.

[0034] In another different implementation, the waterproof membrane can also be directly fixed to the inside of the box with screws. That is, multiple threaded holes are set directly on the inside of the box, and then the waterproof membrane is fixed by screws engaging with the threaded holes.

[0035] In one embodiment, such as Figure 3 As shown, a ring of waterproof adhesive 3 is provided between the perimeter of the waterproof plate 2 and the inner wall of the box 1, thereby further improving the waterproof performance, achieving the purpose of precise waterproofing, improving the stability and reliability of the product during use, and the process of applying a ring of waterproof adhesive is relatively simple and does not affect the appearance of the product at all, ensuring the aesthetics of the box.

[0036] In one embodiment, the waterproof adhesive 3 is an organosilicon sealant. This organosilicon sealant is not only waterproof and moisture-proof, but also insulating and anti-electric, resistant to high and low temperatures, shockproof and drop-proof, and has strong adhesion and good sealing performance. Preferably, the organosilicon sealant selected is the commercially available Kraft K-703 semi-flow organosilicon sealant.

[0037] In other embodiments, the openings of the first and second air inlets / outlets are 50 mm long and 10 mm wide.

[0038] In other embodiments, the enclosure is made of 1.5mm thick steel plate, which is not only high in strength, but also has good corrosion resistance, decorative properties and excellent mechanical properties (good ductility, plasticity and wear resistance).

[0039] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
