Description

Technical Field

[0001] This invention relates to the field of dehumidifier technology, and more specifically, to a dehumidifier with adjustable air outlet speed. Background Technology

[0002] A dehumidifier is a device that draws in humid air, processes it by condensing water molecules into water droplets, and finally expels dry air outside the machine. It is widely used in homes, public places, and various businesses. During operation, humid air enters the dehumidifier through the air inlet, and dry air is expelled through the air outlet. After prolonged use, if the air inlet grille is not cleaned regularly, the air intake area can decrease, reducing ventilation and hindering the dehumidification process over long distances. Summary of the Invention

[0003] To overcome the above shortcomings, the present invention provides a dehumidifier with adjustable air outlet speed, which can adjust the air speed and achieve dehumidification over a longer distance.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a dehumidifier with adjustable air outlet wind speed, comprising a body, an air inlet and an air outlet, a movable sleeve installed at the air outlet, a guide sleeve installed on the movable sleeve, and a wind speed regulating cone sleeve made of thin plate rolled outside the guide sleeve, an inclined abutment surface provided on the outer wall of the guide sleeve, the large diameter end of the wind speed regulating cone sleeve abutting the abutment surface, and the small diameter end of the wind speed regulating cone sleeve facing outward; pulling the outer end of the thin plate outward can reduce the inner diameter of the wind speed regulating cone sleeve to achieve wind speed adjustment.

[0005] When the dehumidifier is working, humid air enters through the inlet and dry air exits through the outlet. The guide sleeve guides the airflow, and the speed-adjusting cone sleeve has low air resistance, concentrating the airflow and increasing its velocity. The thin plate, with its elasticity and rigidity, forms a cone shape when rolled in a fan-shaped loop. By pulling the outer end of the plate outward, the inner diameter of the speed-adjusting cone sleeve is reduced, increasing the airflow velocity and allowing it to reach a greater dehumidification destination. This dehumidifier with adjustable outlet speed, as described in this patent application, enables speed regulation and dehumidification at a greater distance.

[0006] Preferably, an active roller and a driven roller are installed on the guide sleeve, and the thin plate is clamped between the active roller and the driven roller. The rotation of the active roller drives the thin plate to move, thereby adjusting the inner diameter of the wind speed regulating cone sleeve.

[0007] The rotation of the drive roller causes the thin plate to move outward between the drive roller and the driven roller, ensuring smooth and reliable operation.

[0008] Preferably, a wind speed detector is installed at the air outlet, and an adjustment motor for driving the thin plate to roll and move is installed on the air guide sleeve.

[0009] The wind speed detector detects the wind speed at the air outlet. When the detected wind speed is less than the set value, the motor drives the thin plate to wind, reducing the inner diameter of the wind speed regulating cone sleeve and increasing the wind speed, thus realizing intelligent adjustment of the air outlet wind speed.

[0010] Preferably, a positioning strip is connected to the thin plate, and a guide groove is provided on the positioning strip. The outer end of the thin plate passes through the guide groove and is wound. A positioning rod is connected between the positioning strip and the guide sleeve. The positioning rod and the positioning strip are circumferentially locked and can move axially.

[0011] The positioning strip ensures reliable positioning of the wind speed regulating cone sleeve, preventing it from detaching from the guide sleeve. Furthermore, the positioning rod and positioning strip are circumferentially locked, with the positioning strip acting as a force-bearing point during winding, ensuring the smoothness of the winding process. The positioning rod and positioning strip can move axially, ensuring axial movement between the guide sleeve and the wind speed regulating cone sleeve during winding, preventing jamming.

[0012] Preferably, a tension spring connects the positioning strip and the guide sleeve. A rotating ring is installed on the guide sleeve, and several tension springs connect the wind speed regulating cone sleeve and the rotating ring. The tension springs improve the reliability of the wind speed regulating cone sleeve connection and prevent the wind speed regulating cone sleeve from detaching from the guide sleeve.

[0013] As a preferred option, a deformable positioning airbag ring is installed between the inner wall of the wind speed regulating cone sleeve and the guide sleeve.

[0014] The positioning airbag ring can deform, ensuring the stability of the wind speed regulating cone sleeve installation. In particular, during the winding and adjustment process of the wind speed regulating cone sleeve, the positioning airbag ring supports the force, ensuring the reliability of winding.

[0015] Preferably, a fixed sleeve is provided at the air outlet position, and a movable sleeve is axially moved on the fixed sleeve. A preload spring is installed between the movable sleeve and the fixed sleeve.

[0016] During the winding process of the wind speed regulating cone sleeve, the large diameter end abuts against the contact surface, and the diameter of the large diameter end gradually deforms, so the guide sleeve will be pushed. At this time, the movable sleeve moves towards the fixed sleeve, which is stable and reliable.

[0017] Preferably, a universal ball ring is provided on the outer wall of the movable sleeve. The guide sleeve and the universal ball ring are movably connected, allowing the guide sleeve to rotate omnidirectionally around the universal ball ring. A turntable driven by an adjusting motor is installed on the guide sleeve. A drive rod is installed on the turntable. A fixed plate corresponding to the turntable is installed on the machine body. The fixed plate and the turntable are eccentrically set, and the drive rod abuts against the outer wall of the fixed plate. The adjusting motor drives the turntable to rotate, causing the drive rod to move around the outer wall of the fixed plate, thereby realizing the swing of the guide sleeve.

[0018] While the regulating motor adjusts the fan speed, the rotating disc causes the drive rod to move around the outer wall of the fixed disc, thereby oscillating the guide sleeve. This causes the outlet of the fan speed regulating cone to oscillate circumferentially, increasing the air outlet range and preventing the dehumidifier from being affected by a smaller outlet. After the fan speed regulating cone is wound into place, the regulating motor reciprocates in both forward and reverse directions, causing the outlet of the fan speed regulating cone to continue circumferentially oscillating. The angle through which the regulating motor rotates ensures that the turntable completes at least one revolution. The active roller drives the thin plate to make only minor adjustments, resulting in a negligible change in the size of the outlet of the fan speed regulating cone and a minimal impact on the fan speed.

[0019] As a preferred option, several positioning springs are installed between the outer wall of the guide sleeve and the body.

[0020] The positioning spring provides support and positioning for the guide sleeve, ensuring its stable installation.

[0021] Compared with the prior art, the beneficial effects of the present invention are: (1) the dehumidifier can adjust the wind speed and achieve dehumidification at a relatively far distance; (2) the wind speed adjusting cone sleeve has low wind resistance, can gather airflow and increase airflow speed; (3) during the adjustment of the inner diameter of the wind speed adjusting cone sleeve and after the air outlet of the wind speed adjusting cone sleeve is reduced, the air outlet of the wind speed adjusting cone sleeve swings circumferentially with the guide sleeve, increasing the air outlet range, so that the dehumidifier will not affect the dehumidification range due to the reduced air outlet.

[0026] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0027] Example: A dehumidifier with adjustable air outlet speed (see attached document) Figure 1 To be continued Figure 3 The device includes a main body 1, with an air inlet 2 and an air outlet 3. A dehumidification unit is installed inside the main body, removing moisture from humid air and discharging dry air. The specific structure of the dehumidification unit is existing technology and will not be described further here. A movable sleeve 4 is installed at the air outlet position of the main body, and a guide sleeve 5 is installed on the movable sleeve. A fixed sleeve 6 is located at the air outlet position. The movable sleeve moves axially within the fixed sleeve, and a preload spring 7 is installed between the movable sleeve and the fixed sleeve. A stepped surface is provided on the inner wall of the movable sleeve, and several positioning blocks 8 are connected to the end of the fixed sleeve. The stepped surface abuts against the positioning blocks for positioning. The inner wall of the guide sleeve gradually narrows outward to form a frustum-shaped structure. The outer sleeve of the guide sleeve is fitted with a wind speed regulating cone sleeve 10 made of a fan-shaped thin plate 9. An inclined abutment surface 11 is provided on the outer wall of the guide sleeve. The large diameter end of the wind speed regulating cone sleeve abuts against the abutment surface, and the small diameter end of the wind speed regulating cone sleeve faces outward. Pulling the outer end of the thin plate outward can reduce the inner diameter of the wind speed regulating cone sleeve to achieve wind speed regulation.

[0028] A drive roller 12 and a driven roller 13 are installed on the guide sleeve. The thin plate is clamped between the drive roller and the driven roller. The rotation of the drive roller drives the thin plate to move, thereby adjusting the inner diameter of the wind speed regulating cone sleeve. A wind speed detector 14 is installed at the air outlet. An regulating motor 15 for driving the thin plate to wind and move is installed on the guide sleeve. A drive gear 16 is installed on the drive roller, and a drive gear 17 is installed on the output shaft of the regulating motor. The drive gear meshes with the drive gear for transmission. A positioning strip 18 is connected to the thin plate. A guide groove 19 is provided on the positioning strip. The outer end of the thin plate passes through the guide groove for winding. A positioning rod 20 is connected between the positioning strip and the guide sleeve. The positioning rod and the positioning strip are circumferentially locked and can move axially. A tension spring 21 is connected between the positioning strip and the guide sleeve. A sliding groove 22 is provided on the positioning strip. One end of the positioning rod is hinged to the guide sleeve, and a ball head 23 is provided at the other end of the positioning rod. The ball head is movably installed in the sliding groove. A rotating ring 24 is installed on the flow guide sleeve, and several tension springs connect the wind speed regulating cone sleeve and the rotating ring. A deformable positioning airbag ring 25 is installed between the inner wall of the wind speed regulating cone sleeve and the flow guide sleeve.

[0029] A universal ball ring 26 is provided on the outer wall of the movable sleeve. The guide sleeve and the universal ball ring are movably connected, allowing the guide sleeve to rotate omnidirectionally around the universal ball ring. Several positioning springs 27 are installed between the outer wall of the guide sleeve and the machine body. A turntable 28 driven by an adjusting motor is installed on the guide sleeve. A meshing gear 29 is provided on the turntable. The meshing gear meshes with the drive gear, and the outer diameter of the drive gear is greater than the outer diameter of the driving gear, which is greater than the outer diameter of the meshing gear. A drive rod 30 is installed on the turntable. A fixed plate 31 corresponding to the turntable is installed on the machine body. The fixed plate and the turntable are eccentrically set, and the drive rod abuts against the outer wall of the fixed plate. The adjusting motor drives the turntable to rotate, causing the drive rod to move around the outer wall of the fixed plate, thereby realizing the swing of the guide sleeve.

[0030] When the dehumidifier is working, humid air enters through the inlet, and dry air is exhausted through the outlet. The guide sleeve guides the exhaust airflow, and the speed-adjusting cone sleeve has low wind resistance, concentrating the airflow and increasing its velocity. The thin plate, with its elasticity and rigidity, forms a cone shape when wound in a fan-shaped loop. By pulling the outer end of the thin plate outward, the inner diameter of the speed-adjusting cone sleeve is reduced, increasing the airflow and allowing it to reach a greater dehumidification destination. A wind speed detector monitors the airflow speed at the outlet. When the detected speed is lower than a set value, the regulating motor drives the thin plate to wind, reducing the inner diameter of the speed-adjusting cone sleeve and increasing the airflow speed, thus achieving intelligent adjustment of the outlet airflow speed. This dehumidifier with adjustable outlet airflow speed, as described in this patent application, enables speed regulation and dehumidification at a greater distance. During the adjustment of the inner diameter of the wind speed regulating cone sleeve and after the air outlet of the wind speed regulating cone sleeve is reduced, the air outlet of the wind speed regulating cone sleeve swings circumferentially with the guide sleeve, increasing the air outlet range and ensuring that the dehumidifier's dehumidification range is not affected by the reduced air outlet.
