Description

Technical Field

[0001] The present invention relates to the technical field of dehumidifiers. More specifically, the present invention relates to an indoor humidity maintaining dehumidifier based on biomedical research and development. Background Art

[0002] The main components of a rotary dehumidifier include a rotor, a compressor, a condenser, an evaporator, and a control system, etc. Its working principle can be divided into two main processes: adsorption and regeneration. When humid air passes through the rotor, water vapor in the air is adsorbed by the hygroscopic agent on the rotor, thereby reducing the humidity in the air. Subsequently, the rotor enters the regeneration area, and the moisture in the hygroscopic agent is evaporated by heating to restore its moisture absorption capacity. This process is continuous, ensuring the stable operation of the dehumidifier. This technology is not only efficient but also can adapt to various complex working environments and is widely used in industrial fields where humidity needs to be controlled.

[0003] The rotary dehumidifier relies on activated silica gel particles to adsorb moisture in the air. After adsorption saturation, the rotor rotates, causing the activated silica gel particles saturated with water to rotate to the regeneration heater. The regeneration heater heats the activated silica gel particles. After heating to a certain temperature, the activated silica gel particles will dehydrate to a certain extent, enabling the activated silica gel particles to be regenerated for use. Since the power of the regeneration heater is fixed, if the moisture in the air is relatively high, the activated silica gel particles will be saturated with water relatively quickly, and the rotation period of the rotor will decrease. Therefore, it may lead to a lower heating efficiency of the activated silica gel particles, resulting in a poor regeneration effect of the activated silica gel particles, and further reducing the degree of water absorption saturation of the activated silica gel particles, that is, reducing the water absorption saturation time, and thus affecting the water absorption efficiency of the activated silica gel particles as a whole.

[0004] Therefore, to solve the above problems, an indoor humidity maintaining dehumidifier based on biomedical research and development is proposed. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides an indoor humidity maintaining dehumidifier based on biomedical research and development.

[0014] Further, the rotating assembly includes a flange sleeve connected to the bracket, the flange sleeve being coaxially sleeved on the pivot and freely rotatable on the pivot, a sliding rod vertically passing through the periphery of the dehumidification chamber, the sliding rod sliding freely on the periphery of the dehumidification chamber, a rack portion being fixedly connected to the end of the sliding rod that penetrates into the dehumidification chamber, a gear being sleeved on one end of the drive shaft, the gear meshing with the rack portion, an arc-shaped convex block being fixedly connected to the periphery of the flange sleeve, and when the runner rotates, the other end of the sliding rod alternately contacts and connects with the periphery of the flange sleeve and the outer edge of the arc-shaped convex block.

[0015] Further, a roller is rotatably connected to one end of the sliding rod adjacent to the flange sleeve.

[0016] Further, a flange is fixedly connected to the end of the sliding rod that penetrates into the dehumidification chamber, a tension spring is wound around the sliding rod, and both ends of the tension spring are respectively fixedly connected to the inner wall of the dehumidification chamber and the end face of the flange.

[0017] Further, the installation part is hollow inside and open on one side. A end cover is connected to the open end of the installation part, and a vibrating material unit is arranged inside the installation part.

[0018] Further, the vibrating material unit includes an ear block fixedly connected to the end face of the end cover.

[0021] The technical effects and advantages of the present invention are as follows:

[0022] 1. By arranging two sieve plates to slide in the dehumidification bin, the volume of the storage space can be adjusted. Since the storage amount of the activated silica gel particles in the storage space is fixed, when the volume of the storage space increases, the activated silica gel particles in the storage space will be in a loose state, that is, the gaps between the activated silica gel particles increase. In this way, when the external regeneration heater regenerates and heats the activated silica gel particles, hot air can smoothly enter the activated silica gel particles, improving air circulation, and further improving the regeneration efficiency of the activated silica gel particles.

[0023] 2. When the runner rotates, the moving directions of the sieve plates in the dehumidification bin corresponding to the air discharge port and the air supply port are opposite, that is, the sieve plates in the dehumidification bin rotating towards the air discharge port move away from each other, making the activated silica gel particles in the storage space change from a tight state to a loose state, while the sieve plates in the dehumidification bin rotating towards the air supply port move closer to each other, making the activated silica gel particles in the storage space change from a loose state to a tight state. Thus, during the rotation of the runner, the gaps between the activated silica gel particles can be automatically adjusted.

[0024] 3. By setting up the vibration material unit, during the rotation of the drive shaft, the vibration material unit can make the installation part vibrate, thereby generating a vibration effect on the activated silica gel particles in the dehumidification bin. When the sieve plates move away from each other, the activated silica gel particles can be loosened more smoothly. Thus, when the dehumidification bin rotates to the air outlet, the air circulation volume inside the activated silica gel particles can be increased to at least a certain extent, and further improve the regeneration efficiency of the activated silica gel particles.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0036] As Figures 1-9 shown, in this embodiment, the following is disclosed: a dehumidifier for maintaining indoor humidity based on biomedical research and development, which at least includes a housing 1 provided with an air outlet 4 and an air inlet 2. The inner bottom wall of the housing 1 is connected with a mounting seat 10. The top of the mounting seat 10 is fixedly connected with a bracket 9. The upper end of the bracket 9 is rotatably connected with a runner 7 through a pivot 12. A driven pulley is coaxially fixedly connected to the periphery of the runner 7. The top of the mounting seat 10 is connected with a motor seat, and a motor 11 is installed on the motor seat. The output shaft of the motor 11 is sleeved with a driving pulley. The driving pulley and the driven pulley are connected by a belt drive. When the motor 11 is energized and rotates, its output shaft will drive the driving pulley to rotate, and the driving pulley will drive the driven pulley to rotate, so that the driven pulley drives the runner 7 to rotate. A plurality of dehumidification chambers 5 are coaxially fixedly connected to the runner 7 along the axial direction of the runner 7. The axial direction of the dehumidification chamber 5 is parallel to the axial direction of the pivot 12. The air outlet 4 and the air inlet 2 are respectively used in cooperation with two dehumidification chambers 5. Specifically, the air outlet 4 corresponds to the dehumidification chamber 5 located above, and the end face of the air outlet 4 is in contact connection with the end face of the dehumidification chamber 5. The air inlet 2 corresponds to the dehumidification chamber 5 located below, and the end face of the air inlet 2 is in contact connection with the end face of the dehumidification chamber 5. Sieve plates 8 are coaxially clamped at both ends inside the dehumidification chamber 5. A storage space for storing activated silica gel particles is formed between the two sieve plates 8. The sieve plates 8 slide freely along the axial direction of the dehumidification chamber 5 inside the dehumidification chamber 5;

[0037] An annular bracket 23 is fixedly connected inside the dehumidification bin 5. The annular bracket 23 is located between two sieve plates 8. An installation part 20 is fixedly connected to the annular bracket 23. A drive shaft 15 passes through the end face of the installation part 20. The drive shaft 15 is coaxially rotatably connected to the installation part 20 and its two ends respectively pass through the two sieve plates 8. A threaded nut sleeve 21 is embedded in the end face of the sieve plate 8. Each of the two axial ends of the drive shaft 15 is provided with a lead screw section 22. The spiral directions of the two lead screw sections 22 are opposite and they respectively pass through the two threaded nut sleeves 21. The lead screw section 22 and the threaded nut sleeve 21 are used in cooperation, that is, the lead screw section 22 is threadedly passed through the threaded nut sleeve 21. When the lead screw section 22 rotates, the threaded nut sleeve 21 will move along the axial direction of the lead screw section 22 on the lead screw section 22. A flange sleeve 6 is connected to the bracket 9. The flange sleeve 6 is coaxially sleeved on the pivot shaft 12 and freely rotates on the pivot shaft 12. A sliding rod 3 vertically passes through the periphery of the dehumidification bin 5. The sliding rod 3 freely slides on the periphery of the dehumidification bin 5. One end of the sliding rod 3 that penetrates into the dehumidification bin 5 is fixedly connected with a rack portion 16. A gear 14 is sleeved on one end of the drive shaft 15. The gear 14 meshes with the rack portion 16. An arc-shaped convex block 18 is fixedly connected to the periphery of the flange sleeve 6. The position of the arc-shaped convex block 18 corresponds to the position of the air outlet 4. The other end of the sliding rod 3 is rotatably connected with a roller 17. When the runner 7 rotates, the roller 17 alternately contacts and connects with the periphery of the flange sleeve 6 and the outer edge of the arc-shaped convex block 18. One end of the sliding rod 3 that penetrates into the dehumidification bin 5 is fixedly connected with a flange. A tension spring 13 is wound around the sliding rod 3. The two ends of the tension spring 13 are respectively fixedly connected to the inner wall of the dehumidification bin 5 and the end face of the flange. By applying a pulling force to the flange through the tension spring 13, the sliding rod 3 has a tendency to move towards the outside of the dehumidification bin 5;

[0038] When the runner 7 rotates, the roller 17 will roll from the periphery of the flange sleeve 6 to the outer edge of the arc-shaped convex block 18, thereby driving the sliding rod 3 to move in a direction away from the pivot shaft 12, causing the rack portion 16 to mesh and rotate with the gear 14, and further causing the gear 14 to drive the drive shaft 15 to rotate. When the drive shaft 15 rotates, the two lead screw sections 22 will respectively be threadedly screwed with the two threaded nut sleeves 21, thereby driving the two threaded nut sleeves 21 to drive the two sieve plates 8 to move relatively away from each other. When the dehumidification bin 5 rotates to the position of the air outlet 4, the volume of the storage space surrounded by the sieve plates 8 in the dehumidification bin 5 increases, thereby causing the activated silica gel particles in the storage space to change from a compact state to a loose state.

[0039] The installation part 20 is hollow inside and open on one side. A end cover 19 is connected to the open end of the installation part 20. An ear block 28 is fixedly connected to the end face of the end cover 19. A knocking rod 29 vertically penetrates through the ear block 28, and the knocking rod 29 slides freely on the ear block 28. A short pin is horizontally fixedly connected to one end of the knocking rod 29 adjacent to the drive shaft 15. The end of the short pin is rotatably connected to a roller shaft 27. A rotating part 26 is fixedly sleeved on the periphery of the drive shaft 15. A groove 25 for the roller shaft 27 to freely pass through is formed on the end face of the rotating part 26. An avoidance groove 24 communicating with the groove 25 is also formed on the end face of the rotating part 26. The inner side wall of the groove 25 and the avoidance groove 24 are in smooth transition. A ball head is provided at one end of the knocking rod 29 away from the roller shaft 27. A limiting ring 31 is fixedly sleeved on the periphery of the knocking rod 29. A return tension spring 30 is wound around the periphery of the knocking rod 29. Two ends of the return tension spring 30 are respectively fixedly connected to the limiting ring 31 and the outer wall of the ear block 28. The return tension spring 30 has a pulling force on the limiting ring 31, so that the knocking rod 29 has a tendency to move away from the drive shaft 15.

[0040] The working principle of the present invention: Connect the power supply and start the motor 11. The output shaft of the motor 11 rotates and drives the driving pulley to rotate. The driving pulley drives the driven pulley to rotate, so that the driven pulley drives the runner 7 to rotate, and the dehumidification chamber 5 originally corresponding to the air supply port 2 rotates downward. During the downward rotation process, the pivot shaft 12 also rotates synchronously. When the pivot shaft 12 rotates, the runner 7 rotates synchronously, so that one of the dehumidification chambers 5 rotates towards the exhaust port 4. Furthermore, the roller 17 rolls from the periphery of the flange sleeve 6 to the outer edge of the arc-shaped convex block 18, and then drives the sliding rod 3 to move away from the pivot shaft 12, so that the rack part 16 meshes with the gear 14 and rotates. Furthermore, the gear 14 drives the drive shaft 15 to rotate. When the drive shaft 15 rotates, the two lead screw sections 22 are respectively screwed with the two nut sleeves 21, and then drive the two nut sleeves 21 to drive the two sieve plates 8 to move relatively away from each other. When the dehumidification chamber 5 rotates to the exhaust port 4, the volume of the storage space surrounded by the sieve plates 8 in the dehumidification chamber 5 increases. Furthermore, the activated silica gel particles in the storage space change from a compact state to a loose state, and at the same time the tension spring 13 is in a stretched state.

[0041] In addition, when the drive shaft 15 rotates, the roller shaft 27 rolls from the inner wall of the groove 25 into the avoidance groove 24. The return tension spring 30 generates a pulling force on the limiting ring 31, so that the knocking rod 29 quickly moves away from the drive shaft 15. Furthermore, the ball head on the knocking rod 29 quickly knocks the inner wall of the installation part 20, so that the knocking rod 29 generates a knocking vibration force on the installation part 20. Furthermore, the activated silica gel particles in the dehumidification chamber 5 corresponding to the exhaust port 4 are subjected to the vibration force. Under the action of the vibration force, the activated silica gel particles after being saturated with water absorption can be shaken loose, which helps to increase the gap and regeneration efficiency of the activated silica gel particles.

[0042] When the runner 7 continues to rotate, the regenerated activated silica gel particles will rotate with the dehumidification chamber 5, causing the roller 17 to roll from the outer edge of the arc-shaped bump 18 to the periphery of the flange sleeve 6. The elastic potential energy stored in the tension spring 13 is released, driving the sliding rod 3 to move in the direction of the pivot 12. Consequently, the rack portion 16 and the gear 14 engage and rotate in the reverse direction, driving the two sieve plates 8 to approach each other. The sieve plates 8 exert pressure on the activated silica gel particles, transforming them from a loose state to a compact state and reducing the gaps between the activated silica gel particles. Additionally, the roller shaft 27 rolls from the clearance groove 24 to the inner wall of the groove 25, stretching the return spring 30 and storing elastic potential energy, thus completing the regeneration of the activated silica gel particles after water absorption saturation.

[0043] Finally, several points should be noted: First, in the description of this application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense.
