[0003] To address the aforementioned issues, existing patents have provided solutions. However, existing bed unit pipe dehumidification devices lack a structure for regenerating the dehumidification structure. As a result, once the adsorbent material reaches saturation after adsorbing a certain amount of moisture, it cannot restore its adsorption capacity. Consequently, the dehumidification effect of the dehumidification device gradually decreases, eventually leading to the loss of its dehumidification function.

[0004] Therefore, a bed unit duct dehumidification device is proposed. Utility Model Content

[0024] 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A bed unit duct dehumidification device includes a limiting box 1, a dehumidification mechanism 2 fixedly connected to the top of the inner side of the limiting box 1, and a regeneration mechanism 3 fixedly connected to the bottom of the inner side of the limiting box 1.

[0027] The regeneration mechanism 3 includes a limiting shell 31, several heating plates 32, a temperature sensor 33, three connecting pipes 34, a solenoid valve 35, an air supply pipe 36, an electric suction fan 37, and a PLC controller 38. The limiting shell 31 is fixedly connected to the bottom of the inner side of the limiting box 1. The heating plates 32 are installed inside the limiting shell 31. The temperature sensor 33 is installed on the front side of the top of the limiting shell 31. The connecting pipes 34 are fixedly connected to the top of the limiting shell 31. The solenoid valve 35 is fixedly connected to the top of the limiting shell 31. The air supply pipe 36 is fixedly connected to the top of the solenoid valve 35. The electric suction fan 37 is installed on the top of the inner side of the air supply pipe 36. The PLC controller 38 is installed on the top of the front side of the limiting box 1. The top of the air supply pipe 36 is fixedly connected to the bottom of the dehumidification mechanism 2.

[0028] In this embodiment: The limiting box 1 supports and limits the dehumidification mechanism 2 and the regeneration mechanism 3. The limiting shell 31 supports and limits the heating plate 32, temperature sensor 33, and connecting pipe 34. The heating plate 32 generates hot air within the limiting shell 31. The temperature sensor 33 monitors the temperature within the limiting shell 31 in real time and feeds the temperature data back to the PLC controller 38, allowing the PLC controller 38 to adjust the working state of the heating plate 32 according to the set temperature range. The connecting pipe 34 delivers the hot air generated within the limiting shell 31 to the air supply pipe 36. The solenoid valve 35 controls the flow of hot air. When regeneration of the adsorbent material is required, the solenoid valve 35 opens, allowing hot air to enter the dehumidification mechanism 2 through the air supply pipe 36. When the regeneration process is complete or not... When regeneration is required, the solenoid valve 35 closes to prevent hot air leakage and save energy. The air supply pipe 36 delivers hot air from the limiting shell 31 to the bottom of the dehumidification mechanism 2, allowing the hot air to fully contact the silica gel plate 22, molecular sieve plate 23, and activated carbon plate 24 to complete the heating and regeneration process of the adsorbent material. At the same time, it can support and limit the electric suction fan 37. The electric suction fan 37 accelerates the flow speed of hot air in the air supply pipe 36, so that the hot air can be delivered to the dehumidification mechanism 2 faster and more evenly, improving the regeneration efficiency. The PLC controller 38 can control the heating plate 32 to start or stop according to the data of the electromagnetic flow meter 27, and automatically control the power of the heating plate 32, the opening and closing of the solenoid valve 35, and the speed of the electric suction fan 37 according to the temperature data fed back by the temperature sensor 33.

[0029] Specifically, such as Figure 4 As shown, the dehumidification mechanism 2 includes a dehumidification box 21, a silica gel plate 22, a molecular sieve plate 23, an activated carbon plate 24, an air inlet pipe 25, an exhaust pipe 26, and an electromagnetic flow meter 27. The dehumidification box 21 is fixedly connected to the top of the inner side of the limiting box 1.

[0030] Specifically, such as Figure 4As shown, the silica gel plate 22 is fixedly connected to the bottom of the dehumidification box 21, the molecular sieve plate 23 is fixedly connected to the inside of the dehumidification box 21, and the activated carbon plate 24 is fixedly connected to the top of the inside of the dehumidification box 21.

[0031] Specifically, such as Figure 4 As shown, the air inlet pipe 25 is fixedly connected to the right side of the dehumidification box 21. The right side of the air inlet pipe 25 extends through and to the outside of the limiting box 1. The exhaust pipe 26 is fixedly connected to the top of the dehumidification box 21. The top of the exhaust pipe 26 extends through and to the outside of the limiting box 1. The electromagnetic flow meter 27 is installed on the right side of the air inlet pipe 25.

[0032] In this embodiment: by setting the dehumidification box 21 to support and limit the silica gel plate 22, molecular sieve plate 23, activated carbon plate 24, air inlet pipe 25, and exhaust pipe 26, the dehumidification process can be carried out in a relatively enclosed space, improving dehumidification efficiency. The silica gel plate 22 has strong water absorption and can quickly absorb moisture in the air, reducing air humidity. It is also relatively low in cost and can effectively remove a large amount of water vapor, initially improving the air humidity environment. The molecular sieve plate 23, with its uniform microporous structure, can selectively adsorb moisture and other small molecule impurities according to molecular size, exhibiting high adsorption capacity and selectivity for moisture, further enhancing the dehumidification effect. In addition, it can remove some harmful gases and purify the air. The activated carbon plate 24 can not only absorb moisture, but also remove odors, harmful gases and some small particulate impurities from the air, making the dehumidified air cleaner and healthier, and providing better air quality for the bed unit. The air inlet pipe 25 is used to connect to the pipeline of the bed unit, so that the humid air enters the dehumidification box 21. The exhaust pipe 26 discharges the dry and clean air after dehumidification and purification treatment from the dehumidification box 21. The electromagnetic flow meter 27 monitors the air flow in the air inlet pipe 25 in real time and feeds back the flow data to the PLC controller 38, so that it controls the working status of the regeneration mechanism 3 according to the preset program.

[0033] Specifically, such as Figure 5 As shown, a connecting ring 4 is fixedly connected to the surface of the right side of the air intake pipe 25, and several threaded holes 5 are opened on the inner side of the connecting ring 4.

[0034] Specifically, such as Figure 1 As shown, a drain pipe 6 is fixedly connected to the bottom left side of the limiting shell 31, and the left side of the drain pipe 6 passes through the limiting box 1 and is fixedly connected to a one-way valve 7.

[0035] In this embodiment: a connecting ring 4 is provided to facilitate the connection between the air inlet pipe 25 and the bed unit pipe; a threaded hole 5 is provided to provide a threaded interface for easy threaded connection between the air inlet pipe 25 and the bed unit pipe; a drain pipe 6 is provided to drain the moisture generated during the regeneration process, preventing moisture from accumulating in the limiting shell 31; and a one-way valve 7 is provided to prevent external air from backflowing into the limiting shell 31, ensuring stable pressure inside the limiting shell 31 and normal regeneration process, while also preventing impurities and moisture carried by external air from entering.

[0036] Specifically, such as Figure 2 As shown, the heating plates 32 are arranged in a matrix inside the limiting shell 31, and the spacing between adjacent heating plates 32 is equal.

[0037] Specifically, such as Figure 3 As shown, a sealing ring 8 is fixedly connected to the bottom of the connecting pipe 34, and the side of the sealing ring 8 away from the connecting pipe 34 is fixedly connected to the top of the limiting shell 31.

[0038] In this embodiment: by setting the heating plates 32 in a matrix distribution inside the limiting shell 31, the matrix distribution of the heating plates 32 with equal spacing can make the air inside the limiting shell 31 heat up more evenly. By setting the sealing ring 8, hot air can be effectively prevented from leaking from the connection between the connecting pipe 34 and the limiting shell 31, thereby improving the utilization efficiency of hot air.

[0039] Working Principle: First, the user installs the limiting box 1 in a suitable working position. Then, the user connects the bed unit pipe to the threaded hole 5 and the air inlet pipe 25 via the connecting ring 4. After connection, the user powers on and starts the electromagnetic flowmeter 27, PLC controller 38, and temperature sensor 33. At this time, the bed unit pipe discharges the air requiring dehumidification into the bottom of the dehumidification box 21 through the air inlet pipe 25. After entering the dehumidification box 21, the air naturally flows upwards, sequentially contacting the silica gel plate 22, molecular sieve plate 23, and activated carbon plate 24. The silica gel plate 22 quickly absorbs a large amount of moisture from the air, initially reducing air humidity. The molecular sieve plate 23 further removes moisture and some small molecular impurities from the air. The activated carbon plate 24 adsorbs the remaining small amount of moisture and also removes odors, harmful gases, and fine particulate impurities from the air, thus purifying the air comprehensively. The purified air is then discharged through the exhaust pipe 26 to the outside of the limiting chamber 1, completing the dehumidification and purification process. After the device has been used for a period of time, when the electromagnetic flowmeter 27 detects that the airflow entering the dehumidification chamber 21 exceeds a preset threshold, it indicates that the adsorption material may be nearing saturation. At this point, the electromagnetic flowmeter 27 transmits the relevant data to the PLC controller 38. Upon receiving the data, the PLC controller 38 controls the heating plate 32 to start according to a preset program. After starting, the heating plate 32 begins to heat the air inside the limiting chamber 31. After heating for a period of time, the temperature sensor 33 detects that the temperature inside the limiting shell 31 has reached the preset required value. The temperature sensor 33 then transmits a signal to the PLC controller 38. Upon receiving the temperature signal, the PLC controller 38 controls the three solenoid valves 35 to open and the electric suction fan 37 to start working. The electric suction fan 37 generates a strong suction force to accelerate and guide the hot air inside the limiting shell 31, allowing it to quickly enter the inner side of the dehumidification chamber 21 through the connecting pipe 34, solenoid valves 35, and air supply pipe 36. After entering the dehumidification chamber 21, the hot air continues to flow upward and is discharged to the outside of the limiting shell 1 through the exhaust pipe 26. During this process, the hot air continuously stimulates the silica gel plate 22, molecular sieve plate 23, and activated carbon. The activated carbon plate 24 is heated, causing the adsorbed moisture and impurities on these adsorbent materials to desorb, achieving drying and regeneration. Simultaneously, the moisture separated from the silica gel plate 22, molecular sieve plate 23, and activated carbon plate 24 during the regeneration process falls to the bottom of the dehumidification chamber 21 under gravity. At this point, the user opens the one-way valve 7, allowing the water accumulated at the bottom of the dehumidification chamber 21 to drain out through the drain pipe 6 to the outside of the dehumidification chamber 21. The user places an external water collection device at the bottom left of the limiting box 1 to collect the drained water. Finally, when the regeneration time preset by the user in the PLC controller 38 is reached, the PLC controller 38 again controls the solenoid valve 35, the electric suction fan 37, and the heating plate 32 to shut down, putting the device into standby mode.Awaiting the next instruction to regenerate the interior of dehumidifier 21.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
