Description

Technical Field

[0001] This utility model relates to the field of environmental test chamber technology, and in particular to an environmental test chamber with a drying structure. Background Technology

[0002] We artificially create specific environments and apply them to scientific research, production, and testing to conduct specific experiments and tests, thereby facilitating the rapid progress of scientific research, production, and testing.

[0003] However, environmental test chambers with drying structures in related technologies still have shortcomings. Generally, desiccants are used to remove moisture from the environmental test chamber to achieve the effect of dehumidification and drying. However, since desiccants are easily saturated, they cannot be used for long-term testing, which is not conducive to the smooth progress of the test. Therefore, we propose an environmental test chamber with a drying structure to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings mentioned above by proposing an environmental test chamber with a drying structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An environmental test chamber with a drying structure includes an environmental test chamber body, a dehumidification chamber fixedly connected to the top of the environmental test chamber body, a partition slidably disposed inside the dehumidification chamber, a circulating dehumidification and drying mechanism disposed between the environmental test chamber body, the partition and the dehumidification chamber, a temperature and humidity sensor fixedly connected to the top of the environmental test chamber body, a controller fixedly connected to one side of the environmental test chamber body, a chamber body fixedly connected to the top of the dehumidification chamber, and a squeeze dehydration and recovery mechanism disposed between the chamber body, the partition and the dehumidification chamber.

[0007] As a preferred embodiment of this utility model, the circulating dehumidification and drying mechanism includes a hot air blower fixedly connected to the bottom of one side of the environmental test chamber, and a water-absorbing sponge movably placed on the top of the partition. A return pipe is fixedly connected between the hot air blower and the dehumidification chamber. An exhaust pipe is fixedly connected to one side of the dehumidification chamber. A hollow tube is rotatably connected to the bottom end of the exhaust pipe. A horizontal tube is fixedly connected to the bottom end of the hollow tube. Multiple suction heads are fixedly connected to the bottom of the horizontal tube.

[0008] As a preferred embodiment of this utility model, a sealed bearing is fixedly connected to the top inner wall of the environmental test chamber, the bottom end of the exhaust pipe is fixedly connected to the outer ring of the sealed bearing, and the hollow tube is fixedly sleeved inside the inner ring of the sealed bearing.

[0009] As a preferred embodiment of this utility model, a rotary motor is fixedly connected to the top of the environmental test chamber, a rotary shaft is fixedly connected to the output shaft of the rotary motor, an active tooth is fixedly connected to the bottom end of the rotary shaft, and a driven tooth is fixedly sleeved on the outside of the hollow tube, with the active tooth meshing with the driven tooth.

[0010] As a preferred embodiment of this utility model, the extrusion dehydration and recovery mechanism includes a drive motor fixedly connected to the top of the housing, and a bidirectional lead screw rotatably connected to the inner walls of both sides of the housing. A drive bevel gear is fixedly connected to the output shaft of the drive motor, and a driven bevel gear is fixedly sleeved on the outer side of the bidirectional lead screw. The drive bevel gear and the driven bevel gear mesh with each other. Two drive plates are threaded on the outer side of the bidirectional lead screw. A connecting arm 1 is fixedly connected to the top of the drive plate, a connecting arm 2 is fixedly connected to the bottom of the connecting arm 1, a connecting arm 3 is fixedly connected to one side of the connecting arm 2, and an extrusion plate is fixedly connected to the side of the two connecting arms 3 that are close to each other. Several vents are opened on one side of the extrusion plate, and the water-absorbing sponge is movably abutted between the two extrusion plates.

[0011] As a preferred embodiment of this utility model, the top of the housing is provided with a rectangular opening, and the two drive plates are respectively slidably fitted into the corresponding rectangular openings.

[0012] As a preferred embodiment of this utility model, the dehumidification box has guide openings on both sides, and the two connecting arms are slidably sleeved in the corresponding guide openings.

[0013] As a preferred embodiment of this utility model, the bottom of the partition is provided with several water outlets, a pressure sensor is fixedly connected to the bottom inner wall of the dehumidification box, four support legs are fixedly connected to the top of the pressure sensor, the four support legs are fixedly connected to the bottom of the partition, and a drain pipe is fixedly connected to one side bottom of the dehumidification box, and a control valve is provided on the drain pipe.

[0014] In this invention, the environmental test chamber with a drying structure uses a temperature and humidity sensor to detect the humidity inside the chamber. When the humidity is too high, a hot air blower is activated to dehumidify and dry the chamber. Water vapor is drawn into the suction head, horizontal tube, hollow tube, and exhaust pipe by the hot air blower, and finally drawn into the dehumidification chamber. The absorbent sponge absorbs the moisture in the air, and the dry air flows back into the hot air blower and the environmental test chamber for further dehumidification and drying, resulting in better dehumidification and drying. A rotating motor drives the rotation of the rotating shaft and the active gear, which in turn drives the rotation of the driven gear, hollow tube, horizontal tube, and suction head, making the absorption of water vapor more uniform and comprehensive, and accelerating the dehumidification and drying of the environmental test chamber. When the humidity is lower than the set value, the temperature and humidity sensor sends a signal to the controller, which then shuts off the hot air blower.

[0015] In this invention, the environmental test chamber with a drying structure continuously absorbs water from the absorbent sponge, causing the sponge's weight to increase. A pressure sensor is used to weigh the partition and the absorbent sponge. When the weight reaches a trigger value, the pressure sensor sends a signal to the controller, which then starts the drive motor. The drive motor rotates the active bevel gear, which in turn rotates the driven bevel gear and the double-acting screw. The double-acting screw causes the two drive plates, connecting arm three, and two squeezing plates to move closer together, squeezing the absorbent sponge. This squeezes out the water from the sponge and discharges it through the outlet into the dehumidification chamber below the partition, eventually draining it through the drain pipe. After discharge, the drive motor is restarted in reverse, causing the two squeezing plates to move away from each other and reset, while the absorbent sponge dehydrates and regains its water-absorbing and moisture-absorbing effect.

[0016] This utility model has a reasonable structural design and can circulate dehumidification and drying, which makes the dehumidification and drying efficiency faster and ensures that the environmental test chamber is kept within the specified range. When the water-absorbing sponge reaches saturation, it can be automatically squeezed to dehydrate it and restore its water absorption and moisture absorption effect, so as to dehumidify and dry for a long time and ensure long-term test use.

[0022] 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.

[0023] Reference Figure 1-4 An environmental test chamber with a drying structure includes an environmental test chamber body 1, a dehumidification chamber 2 fixedly connected to the top of the environmental test chamber body 1, a partition 8 slidably arranged inside the dehumidification chamber 2, a circulating dehumidification and drying mechanism 6 arranged between the environmental test chamber body 1, the partition 8 and the dehumidification chamber 2, a temperature and humidity sensor 3 fixedly connected to the top of the environmental test chamber body 1, a controller 4 fixedly connected to one side of the environmental test chamber body 1, a chamber body 5 fixedly connected to the top of the dehumidification chamber 2, and a squeezing dehydration and recovery mechanism 7 arranged between the chamber body 5, the partition 8 and the dehumidification chamber 2.

[0024] Furthermore, refer to Figure 1-3 As shown, the circulating dehumidification and drying mechanism 6 includes a hot air blower 601 fixedly connected to the bottom of one side of the environmental test chamber 1, and a water-absorbing sponge 612 movably placed on the top of the partition 8. A return pipe 602 is fixedly connected between the hot air blower 601 and the dehumidification chamber 2. An exhaust pipe 603 is fixedly connected to one side of the dehumidification chamber 2. A hollow pipe 609 is rotatably connected to the bottom end of the exhaust pipe 603. A horizontal pipe 610 is fixedly connected to the bottom end of the hollow pipe 609. Multiple suction heads 611 are fixedly connected to the bottom of the horizontal pipe 610. A rotary motor 604 is fixedly connected to the top of the environmental test chamber 1.

[0025] Using the above scheme: The humidity inside the environmental test chamber 1 can be detected by the temperature and humidity sensor 3. When the humidity is too high, the hot air blower 601 is activated, blowing hot air to dehumidify and dry the environmental test chamber 1. Water vapor is drawn in by the hot air blower 601 and enters the suction head 611, horizontal pipe 610, hollow pipe 609, and exhaust pipe 603, and is finally drawn into the dehumidification chamber 2. The water-absorbing sponge 612 absorbs the water vapor in the air, and the dry air flows into the dehumidification chamber 2 from the return pipe 602. The hot air blower 601 blows hot air again to dehumidify and dry the environmental test chamber 1, making the dehumidification and drying effect better. The rotating motor 604 drives the rotating shaft 605 and the active gear 606 to rotate. The active gear 606 drives the driven gear 608, hollow tube 609, horizontal tube 610 and suction head 611 to rotate, making the absorption of water vapor more uniform and comprehensive, and accelerating the dehumidification and drying of the environmental test chamber 1. When the humidity is lower than the set value, the temperature and humidity sensor 3 sends a signal to the controller 4, and the controller 4 shuts down the hot air blower 601.

[0026] Furthermore, a sealed bearing 607 is fixedly connected to the top inner wall of the environmental test chamber 1, the bottom end of the exhaust pipe 603 is fixedly connected to the outer ring of the sealed bearing 607, and the hollow pipe 609 is fixedly sleeved in the inner ring of the sealed bearing 607, which facilitates the rotational communication between the hollow pipe 609 and the exhaust pipe 603, while not hindering the rotation of the hollow pipe 609, and ensuring the sealing of the connection between the hollow pipe 609 and the exhaust pipe 603.

[0027] Furthermore, refer to Figure 1 , Figure 2 and Figure 4 As shown, the extrusion dewatering and recovery mechanism 7 includes a drive motor 705 fixedly connected to the top of the housing 5, and a bidirectional lead screw 708 rotatably connected to the inner walls of both sides of the housing 5. A drive bevel gear 706 is fixedly connected to the output shaft of the drive motor 705. A driven bevel gear 707 is fixedly sleeved on the outer side of the bidirectional lead screw 708. The drive bevel gear 706 meshes with the driven bevel gear 707. Two drive plates 710 are threaded on the outer side of the bidirectional lead screw 708. A connecting arm 1 711 is fixedly connected to the top of the drive plate 710. A connecting arm 2 714 is fixedly connected to the bottom of the connecting arm 1 711. One side of the connecting arm 2 714... A connecting arm 712 is fixedly connected. A squeezing plate 713 is fixedly connected to one side of the two connecting arms 712 that are close to each other. Several vents 715 are opened on one side of the squeezing plate 713. A water-absorbing sponge 612 is movably abutted between the two squeezing plates 713. Several water outlets 702 are opened at the bottom of the partition 8. A pressure sensor 704 is fixedly connected to the bottom inner wall of the dehumidification box 2. Four support legs 703 are fixedly connected to the top of the pressure sensor 704. The four support legs 703 are fixedly connected to the bottom of the partition 8. A drain pipe 701 is fixedly connected to one side of the bottom of the dehumidification box 2. A control valve is installed on the drain pipe 701.

[0028] The above scheme is adopted as follows: As the absorbent sponge 612 continuously absorbs water, its weight increases. The pressure sensor 704 can weigh the partition 8 and the absorbent sponge 612. When the weight reaches the trigger value, the pressure sensor 704 sends a signal to the controller 4. The controller 4 starts the drive motor 705, which drives the rotation of the active bevel gear 706. The active bevel gear 706 drives the rotation of the driven bevel gear 707 and the bidirectional lead screw 708. The bidirectional lead screw 708 drives the two drive plates 710, the connecting arm 712, and the two squeezing plates 713 to move closer together, squeezing the absorbent sponge 612. This squeezes the water out of the absorbent sponge 612 and discharges it from the outlet 702 into the dehumidification box 2 below the partition 8, finally draining it through the drain pipe 701. After discharge, the drive motor 705 is restarted in reverse, causing the two squeezing plates 713 to move away and reset, while the absorbent sponge 612 dehydrates and regains its water absorption and moisture-absorbing effect.

[0029] Furthermore, a rectangular opening 709 is provided on the top of the housing 5, and two drive plates 710 are slidably fitted into the corresponding rectangular openings 709. Guide openings are provided on both sides of the dehumidification box 2, and two connecting arms 712 are slidably fitted into the corresponding guide openings, which facilitates the guidance of the connecting arms 712 and the drive plates 710, making their movement more stable and smooth.

[0030] In this invention, the humidity inside the environmental test chamber 1 can be detected by the temperature and humidity sensor 3. When the humidity is too high, the hot air blower 601 is activated, blowing hot air to dehumidify and dry the environmental test chamber 1. Water vapor is drawn in by the hot air blower 601 and enters the suction head 611, horizontal pipe 610, hollow pipe 609, and exhaust pipe 603, and is finally drawn into the dehumidification chamber 2. The water-absorbing sponge 612 absorbs the water vapor in the air, and the dry air flows into the dehumidification chamber 2 from the return pipe 602. The hot air blower 601 blows hot air again to dehumidify and dry the environmental test chamber 1, making the dehumidification and drying effect better. The rotating motor 604 drives the rotating shaft 605 and the active gear 606 to rotate. The active gear 606 drives the driven gear 608, hollow tube 609, horizontal tube 610 and suction head 611 to rotate, making the absorption of water vapor more uniform and comprehensive, and accelerating the dehumidification and drying of the environmental test chamber 1. When the humidity is lower than the set value, the temperature and humidity sensor 3 sends a signal to the controller 4, and the controller 4 shuts down the hot air blower 601.

[0031] As the absorbent sponge 612 continuously absorbs moisture, its weight increases. The pressure sensor 704 weighs the partition 8 and the absorbent sponge 612. When the weight reaches a trigger value, the pressure sensor 704 sends a signal to the controller 4. The controller 4 then starts the drive motor 705, which rotates the active bevel gear 706. The active bevel gear 706 rotates the driven bevel gear 707 and the bidirectional lead screw 708. The bidirectional lead screw 708 causes the two drive plates 710, the connecting arm 712, and the two squeezing plates 713 to move closer together, squeezing the absorbent sponge 612. This squeezes the water out of the sponge 612 and drains it from the outlet 702 into the dehumidification box 2 below the partition 8, finally exiting through the drain pipe 701. After drainage, the drive motor 705 is restarted in reverse, causing the two squeezing plates 713 to move away and reset, allowing the absorbent sponge 612 to dehydrate and regain its moisture-absorbing effect.
