Description

Technical Field

[0001] This utility model relates to the field of dehumidifier technology, specifically a dehumidifier for the sale of electronic components. Background Technology

[0002] Electronic components are the building blocks of electronic parts and small machines and instruments. They are usually composed of several parts and are of great significance to social development. Therefore, the demand for them is huge. After manufacturers produce them, they need to be displayed and sold. Because they are quite delicate, they must be displayed and sold in appropriate dehumidifying cabinets to avoid moisture damage.

[0003] According to the authorization announcement number CN221083259U, a dehumidifying cabinet for selling electronic components is proposed, including a cabinet body. The bottom of the buffer structure is movably connected to rollers. A sliding groove is formed on the inner side wall of the cabinet body. A placement frame is movably connected inside the cabinet body. Slide plates are fixedly connected to both sides of the placement frame. A dehumidifying box is fixedly connected to the back of the cabinet body. A circulating fan is fixedly connected to the lower end of the inner side wall of the dehumidifying box. A sealing plate is movably connected to the upper end of the back of the dehumidifying box. A humidity sensor body detects the humidity in the air inside the cabinet through a set detection mechanism, avoiding the inconvenience caused by untimely drying or continuous drying. When not in use, the humidity sensor body can be protected by a protective plate and a protective groove to prevent damage caused by accidental collision when handling electronic components or cleaning the inner wall of the cabinet.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, the design of the aforementioned dehumidifying cabinet does not consider the need to detect the saturation of the silica gel drying plate. This results in a lack of objectivity and timeliness in maintenance, posing a risk of dehumidification failure. Users cannot know when the silica gel drying plate reaches its adsorption limit and can only check it by experience or by manually disassembling the sealing plate periodically. This leads to delayed maintenance. If the drying plate is not replaced in time, it will lose its dehumidification ability, and the humidity inside the cabinet will rise again, affecting the storage of electronic components. Frequent disassembly and inspection will increase operating costs and may damage the airtightness of the dehumidifying cabinet. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a moisture-proof cabinet for the sale of electronic components, which has the advantage of reminding replacements and solves the problems of delayed or excessive maintenance in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a moisture-proof cabinet for selling electronic components, comprising a cabinet body, a circulating fan, a drying chamber, a diatomaceous earth drying plate, an exhaust pipe, an exhaust pipe, and a first temperature and humidity sensor. The circulating fan is fixedly installed on the back of the cabinet body. The drying chamber is connected to the input end of the circulating fan. The exhaust pipe is connected to the top of the drying chamber, and the other end of the exhaust pipe is connected to the top inside the cabinet body. The exhaust pipe is connected to the output end of the circulating fan, and the other end of the exhaust pipe is connected to the bottom inside the cabinet body. The diatomaceous earth drying plate is disposed inside the drying chamber. The first temperature and humidity sensor is fixedly installed on the top inside the cabinet body. A detection box is provided on the surface of the exhaust pipe. A second temperature and humidity sensor is fixedly installed on the left side of the detection box, and the detection end of the second temperature and humidity sensor is located inside the detection box. A controller is fixedly installed on the left side of the back of the cabinet body. The controller is electrically connected to the first temperature and humidity sensor and the second temperature and humidity sensor respectively through wires. A sealing door is movably connected to the left side of the drying chamber through a hinge. A reinforcement component is fixedly installed on the left side of the bottom of the drying chamber.

[0007] As a preferred embodiment of this utility model, indicator lights are fixedly installed on the left and right sides of the front top of the cabinet, and the indicator lights are electrically connected to the controller via wires.

[0008] As a preferred embodiment of this utility model, the reinforcing component includes a mounting block, which is fixedly installed on the left side of the bottom of the drying oven. A connecting rod is rotatably connected inside the mounting block, and a connecting plate is fixedly connected to the left end of the connecting rod. A tightening screw is threadedly connected to the top of the connecting plate, and the tightening screw is used to press against the sealing door.

[0009] As a preferred embodiment of this invention, a sealing gasket is affixed to the side of the sealing door that contacts the drying oven, and the sealing gasket is made of natural rubber.

[0010] As a preferred embodiment of this utility model, a clamping plate is fixedly connected to the right end of the clamping screw, and the contact area between the clamping plate and the sealing door is greater than the contact area between the clamping screw and the sealing door.

[0011] As a preferred embodiment of this invention, limiting blocks are provided on both the left and right sides of the mounting block, and the limiting blocks are fixedly connected to the connecting rod.

[0012] As a preferred embodiment of this utility model, a rotating block is fixedly connected to the front end of the clamping screw, and the rotating block is arranged in a plum blossom shape.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model establishes a dual-sensor detection system by setting a detection box and a second temperature and humidity sensor on the surface of the air outlet pipe, combined with the first temperature and humidity sensor. The system achieves intelligent monitoring and control through a controller. During use, the system accurately determines the adsorption saturation state of the silica gel drying plate by comparing the humidity data difference between the first and second temperature and humidity sensors. When the drying plate is close to saturation, its dehumidification efficiency decreases, resulting in an increase in the humidity of the air discharged from the air outlet pipe. The difference between the two sensor data narrows, and the system issues a replacement warning accordingly. This solves the problem of delayed or excessive maintenance in the prior art and achieves the effect of reminding for replacement.

[0015] 2. This utility model uses an indicator light electrically connected to the controller on the front top of the cabinet to visually remind operators to replace the diatomaceous earth drying board in a timely manner based on changes in humidity inside the cabinet. When the diatomaceous earth drying board is saturated and the humidity of the cabinet exceeds the set threshold, the indicator light will illuminate, avoiding frequent manual inspections, improving maintenance efficiency, preventing electronic components from getting damp due to drying board failure, and ensuring storage safety.

[0016] 3. By setting up a reinforcement component, through the cooperation of the mounting block, connecting rod, connecting plate and tightening screw, this utility model can reinforce the sealing door after it is closed, preventing the sealing door from loosening due to vibration or other reasons during long-term use, ensuring the sealing performance of the drying box, and thus ensuring the moisture-proof effect of the dehumidifying cabinet. At the same time, this structure is simple to operate and easy to maintain. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, this utility model provides a moisture-proof cabinet for selling electronic components, including a cabinet body 1, a circulating fan 2, a drying chamber 3, a diatomaceous earth drying plate 4, an exhaust pipe 5, an exhaust pipe 6, and a first temperature and humidity sensor 7. The circulating fan 2 is fixedly installed on the back of the cabinet body 1. The drying chamber 3 is connected to the input end of the circulating fan 2. The exhaust pipe 5 is connected to the top of the drying chamber 3, and the other end of the exhaust pipe 5 is connected to the top inside the cabinet body 1. The exhaust pipe 6 is connected to the output end of the circulating fan 2, and the other end of the exhaust pipe 6 is connected to the bottom inside the cabinet body 1. The diatomaceous earth drying plate 4 is placed in the drying chamber. Inside the drying oven 3, the first temperature and humidity sensor 7 is fixedly installed on the top inside the cabinet 1. A detection box 8 is provided on the surface of the air outlet pipe 6. A second temperature and humidity sensor 9 is fixedly installed on the left side of the detection box 8. The detection end of the second temperature and humidity sensor 9 is located inside the detection box 8. A controller 10 is fixedly installed on the left side of the back of the cabinet 1. The controller 10 is electrically connected to the first temperature and humidity sensor 7 and the second temperature and humidity sensor 9 through wires. A sealing door 11 is movably connected to the left side of the drying oven 3 through a hinge. A reinforcement component 12 is fixedly installed on the left side of the bottom of the drying oven 3.

[0023] refer to Figure 1 , Figure 2 and Figure 3 Indicator lights 13 are fixedly installed on the left and right sides of the top front side of the cabinet 1, and the indicator lights 13 are electrically connected to the controller 10 through wires.

[0024] As a technical optimization of this utility model, the indicator light 13, which is electrically connected to the controller 10 on the top front side of the cabinet 1, can remind the operator to replace the diatomaceous earth drying plate 4 in a timely manner based on the change in humidity inside the cabinet 1. When the diatomaceous earth drying plate 4 is saturated and the humidity of the cabinet 1 exceeds the set threshold, the indicator light 13 will light up, avoiding frequent manual inspections, improving maintenance efficiency, preventing electronic components from getting damp due to the failure of the diatomaceous earth drying plate 4, and ensuring storage safety.

[0025] refer to Figure 1 , Figure 2 and Figure 3The reinforcement component 12 includes a mounting block 121, which is fixedly installed on the left side of the bottom of the drying oven 3. A connecting rod 122 is rotatably connected inside the mounting block 121. A connecting plate 123 is fixedly connected to the left end of the connecting rod 122. A tightening screw 124 is threadedly connected to the top of the inside of the connecting plate 123. The tightening screw 124 is used to press against the sealing door 11.

[0026] As a technical optimization of this utility model, by setting up a reinforcing component 12, and through the cooperation of mounting block 121, connecting rod 122, connecting plate 123 and tightening screw 124, the sealing door 11 can be reinforced after it is closed, preventing the sealing door 11 from loosening due to vibration or other reasons during long-term use, ensuring the sealing performance of the drying box 3, and thus ensuring the moisture-proof effect of the dehumidifying cabinet. At the same time, this structure is simple to operate and easy to maintain.

[0027] refer to Figure 1 , Figure 2 and Figure 3 The sealing door 11 has a sealing gasket 14 attached to the side that contacts the drying oven 3. The sealing gasket 14 is made of natural rubber.

[0028] As a technical optimization of this utility model, a natural rubber sealing gasket 14 is pasted at the contact point between the sealing door 11 and the drying oven 3. The good elasticity and sealing properties of natural rubber can effectively fill the gap between the sealing door 11 and the drying oven 3, further enhancing the sealing performance of the drying oven 3, preventing external humid air from entering the drying oven 3, and improving the moisture-proof ability of the dehumidifier. At the same time, the natural rubber material also has the characteristics of aging resistance and corrosion resistance, extending the service life of the sealing gasket 14.

[0029] refer to Figure 1 , Figure 2 and Figure 3 The right end of the clamping screw 124 is fixedly connected to a clamping plate 15, and the contact area between the clamping plate 15 and the sealing door 11 is greater than the contact area between the clamping screw 124 and the sealing door 11.

[0030] As a technical optimization of this utility model, by setting the clamping plate 15, the contact area with the sealing door 11 is increased, so that when clamping the sealing door 11, the pressure can be more evenly distributed on the sealing door 11, avoiding deformation or damage to the sealing door 11 due to excessive local pressure. At the same time, the clamping effect is enhanced, the fixing stability of the reinforcing component 12 to the sealing door 11 is improved, and the sealing performance of the drying oven 3 is guaranteed.

[0031] refer to Figure 1 , Figure 2 and Figure 3Limiting blocks 16 are provided on both the left and right sides of the mounting block 121, and the limiting blocks 16 are fixedly connected to the connecting rod 122.

[0032] As a technical optimization of this utility model, by setting a limiting block 16, the limiting block 16 can restrict the use of the connecting rod 122, so as to prevent the connecting rod 122 from detaching from the mounting block 121.

[0033] refer to Figure 1 , Figure 2 and Figure 3 The front end of the clamping screw 124 is fixedly connected to a rotating block 17, which is arranged in a plum blossom shape.

[0034] As a technical optimization of this utility model, by setting a plum blossom-shaped rotating block 17, it is easier for the operator to hold and apply force. Compared with the ordinary screw head, the plum blossom-shaped structure provides better friction, enabling the operator to rotate and tighten the screw 124 more easily and accurately, improving the operational convenience of the reinforcement component 12, while also reducing operational errors caused by slippage and improving work efficiency.

[0035] The working principle and usage process of this utility model are as follows: During use, after the circulating fan 2 is started, the dehumidification process of the dehumidifying cabinet is activated. The humid air at the top of the cabinet 1 is drawn into the drying chamber 3 through the exhaust pipe 5 by the suction of the circulating fan 2. The diatomaceous earth drying plate 4 inside the drying chamber 3 adsorbs moisture from the air, transforming the humid air into dry air. The dried air is then transported back to the bottom of the cabinet 1 from the output of the circulating fan 2 through the exhaust pipe 6, forming a top-to-bottom air circulation path within the cabinet 1. This continuously dehumidifies the internal environment of the cabinet 1, ensuring that electronic components are stored in a dry environment. The first temperature and humidity sensor 7 and the second temperature and humidity sensor 9 inside the surface detection box 8 of the air outlet 6 collect humidity data inside the cabinet 1 and the air after drying in real time, and transmit the data to the controller 10. The controller 10 analyzes and processes the two sets of data and calculates the humidity difference between them: when the diatomaceous earth drying plate 4 is in the effective adsorption stage, it can efficiently remove moisture from the air, so that the humidity of the air after being treated by the drying box 3 is significantly reduced. At this time, the difference between the humidity inside the cabinet 1 (H1) detected by the first temperature and humidity sensor 7 and the humidity of the air in the air outlet 6 (H2) detected by the second temperature and humidity sensor 9 (ΔH=H1-H2) is maintained at a reasonable set value. Within a certain range (e.g., ΔH ≥ 5%RH), the controller 10 controls the circulating fan 2 to operate at normal power to maintain stable dehumidification. As the diatomaceous earth drying plate 4 gradually becomes saturated with adsorbed moisture, its dehumidification capacity decreases, and the humidity of the air in the outlet pipe 6 increases. The humidity difference between the two gradually decreases. When ΔH < 2%RH, the controller 10 determines that the diatomaceous earth drying plate 4 has reached its adsorption limit and needs to be replaced. It then sends an electrical signal to the indicator light 13 through a wire, causing the indicator light 13 to illuminate and reminding the operator to replace the diatomaceous earth drying plate 4 in time. When replacing the plate, the operator can loosen the clamping screw 124 by rotating the block 17 and move the clamping plate 15 through the connecting rod 122 and the mounting block 121. Rotate downwards, and the operator can then open the sealing door 11 to replace the diatomaceous earth drying plate 4, preventing dehumidification failure from affecting the storage of electronic components. After replacement, close the sealing door 11. With the help of the natural rubber sealing gasket 14, it fits tightly when closed, effectively preventing external humid air from entering the drying chamber 3 and ensuring the dehumidification effect of the internal diatomaceous earth drying plate 4. After closing the sealing door 11, rotate the connecting rod 122 to reset the connecting plate 123. Then, rotate the clamping screw 124 to drive the clamping plate 15 to press the sealing door 11 tightly against the drying chamber 3, further enhancing the fixing effect of the sealing door 11, ensuring the airtightness of the drying chamber 3, and maintaining the overall moisture-proof performance of the dehumidifier.

[0036] In summary, this dehumidifying cabinet for selling electronic components uses a dual-sensor detection system formed by installing a detection box 8 and a second temperature and humidity sensor 9 on the surface of the air outlet pipe 6, combined with the first temperature and humidity sensor 7. Intelligent monitoring and control are achieved through a controller 10. During use, the system accurately determines the adsorption saturation state of the silica gel drying plate by comparing the humidity data difference between the first and second temperature and humidity sensors 7 and 9. When the drying plate approaches saturation, its dehumidification efficiency decreases, leading to an increase in the humidity of the air discharged from the air outlet pipe 6. This reduces the difference between the two sensor data, prompting the system to issue a replacement warning. This solves the problems of delayed or excessive maintenance in the prior art.
