Description

Technical Field

[0001] This utility model relates to the field of ventilation device technology, specifically a dehumidifying rotary ventilation device. Background Technology

[0002] A dehumidifying impeller is a common core component of air dehumidification equipment. It mainly consists of a honeycomb-shaped disc covered with moisture-absorbing material. During operation, humid air first passes through a part of the disc, where the moisture in the air is firmly adsorbed by the moisture-absorbing material. At the same time, the disc rotates slowly. Subsequently, heated regenerated air flows through another part of the disc, heating and desorbing the adsorbed moisture and carrying it away. In this way, the disc continuously rotates, switching between the moisture absorption zone and the regeneration zone, to achieve continuous and stable removal of moisture from the air.

[0003] Existing dehumidifying impellers are usually integrated with the drive shaft. While this structure provides good initial rigidity, after long-term use, the impeller is prone to deformation due to the drastic temperature changes caused by the continuous switching between the high-temperature regeneration zone and the low-temperature moisture absorption zone. Secondly, the moisture-absorbing material may experience minor wear or aging during repeated moisture absorption and desorption, which seriously affects the moisture absorption efficiency of the equipment. In addition, the non-replaceability of the impeller significantly increases the hidden maintenance costs for users. In view of this, we provide a dehumidifying impeller ventilation device. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a dehumidifying rotary ventilation device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dehumidifying rotary ventilation device, comprising a wheel and a drive shaft, wherein a protrusion is fixedly connected to one side of the outer wall of the drive shaft and the protrusion is located inside the wheel, a release button is slidably connected to the top of the inner wall of the drive shaft, and a limiting ring is added to the top of the outer wall of the release button, and multiple slide rails are fixedly connected to both sides of the inner wall of the drive shaft.

[0006] A snap-fit ​​component is provided on one side of the inside of the drive shaft, and one side of the outer wall of the snap-fit ​​component extends to one side of the inside of the wheel. Multiple compression springs are fixedly connected to one side of the outer wall of the snap-fit ​​component, and a snap-fit ​​groove is provided on one side of the inner wall of the wheel.

[0007] As described above, a rectangular groove is provided on one side of the inner wall of the wheel, and the width of the inner wall of the rectangular groove is the same as the width of the outer wall of the protrusion. An arc-shaped top is added to the top surface of the protrusion, and the two sides of the outer wall of the protrusion are slidably connected to the two sides of the inner wall of the rectangular groove.

[0008] As described above, the outer wall of the slide rail penetrates one side of the inner wall of the snap-fit ​​component, and the outer wall of the slide rail is slidably connected to one side of the inner wall of the snap-fit ​​component.

[0009] As described above, the two ends of the compression spring abut against the outer wall of the snap-fit ​​component and the inner wall of the drive shaft, respectively.

[0010] As described above, the outer wall of the snap-fit ​​component is tightly fitted to the inner wall of the snap-fit ​​groove opened inside the wheel, the bottom surface of the snap-fit ​​component is a planar structure, and one side of the outer wall of the snap-fit ​​component is snapped and connected to the inner wall of the snap-fit ​​groove, and the center of the bottom surface of the wheel abuts against the bottom outer wall of the drive shaft.

[0011] As described above, a groove is provided on the top of the inner wall of the drive shaft, and the top of the inner wall of the groove is in contact with the top surface of the limiting ring. The outer wall of the limiting ring is slidably connected to the top of the inner wall of the groove.

[0012] As described above, a sloping surface is provided on one side of the outer wall of the snap-fit ​​component, and the sloping surface provided on the outer wall of the snap-fit ​​component is in close contact with the bottom outer wall of the release button.

[0013] Compared with existing technologies, this dehumidifying rotary ventilation device has the following advantages:

[0014] I. When the wheel needs to be replaced due to deformation or aging of the internal moisture-absorbing material, simply press the release button. Its bottom end slides along the inclined surface of the locking component, forcing the locking component to squeeze the compression spring and retract into the drive shaft. Once the locking component is completely disengaged from the locking groove, the axial constraint between the wheel and the drive shaft can be immediately released. The old wheel can then be removed directly along the outer wall of the drive shaft. Subsequently, the rectangular groove on the inner wall of the new wheel is aligned with the protrusion on the drive shaft and pushed in. The locking component will automatically engage in the locking groove inside the new wheel under the compression spring, thereby significantly reducing the maintenance costs caused by wheel failure.

[0015] II. This utility model achieves torque transmission between the wheel and the drive shaft by setting a protrusion on one side of the outer wall of the drive shaft and fitting the protrusion into the rectangular groove inside the wheel. It also effectively constrains the radial offset of the wheel through close cooperation.

[0016] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[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] like Figure 1-6 As shown, this utility model provides a technical solution: a dehumidifying rotary ventilation device, including a wheel 1 and a drive shaft 2. A protrusion 201 is fixedly connected to one side of the outer wall of the drive shaft 2, and the protrusion 201 is located inside the wheel 1. A release button 202 is slidably connected to the top of the inside of the drive shaft 2, and a limiting ring 203 is added to the top of the outer wall of the release button 202. Multiple slide rails 204 are fixedly connected to both sides of the inner wall of the drive shaft 2.

[0026] A snap-fit ​​component 205 is provided on one side of the inside of the drive shaft 2, and one side of the outer wall of the snap-fit ​​component 205 extends to one side of the inside of the wheel 1. Multiple compression springs 206 are fixedly connected to one side of the outer wall of the snap-fit ​​component 205, and a snap-fit ​​groove 101 is provided on one side of the inner wall of the wheel 1.

[0027] When the wheel 1 needs to be replaced due to deformation or aging of the internal moisture-absorbing material, simply press the release button 202. Its bottom end will slide along the inclined slope of the locking member 205 to release the axial constraint between the wheel 1 and the drive shaft 2, allowing the user to replace the wheel 1 independently, thereby reducing the maintenance cost caused by the failure of the wheel 1.

[0028] like Figure 3 , Figure 4 and Figure 5As shown, a rectangular groove 102 is provided on one side of the inner wall of the wheel 1, and the width of the inner wall of the rectangular groove 102 is the same as the width of the outer wall of the protrusion 201. An arc-shaped top is added to the top surface of the protrusion 201, and the outer walls of the protrusion 201 are slidably connected to the inner walls of the rectangular groove 102.

[0029] The width of the rectangular groove 102 on the inner wall of the wheel 1 is precisely matched with the width of the protrusion 201 on the outer wall of the drive shaft 2. The top of the protrusion 201 is designed to be arc-shaped, and its two sides can slide smoothly along the inner wall of the rectangular groove 102 to achieve the initial positioning and radial limiting function of the wheel 1 and the drive shaft 2.

[0030] like Figure 6 As shown, the outer wall of the slide rail 204 penetrates one side of the inner wall of the snap-fit ​​member 205, and the outer wall of the slide rail 204 is slidably connected to one side of the inner wall of the snap-fit ​​member 205.

[0031] The slide rail 204 passes through the locking member 205, which can move on the outer wall of the slide rail 204. The movement trajectory of the locking member 205 is constrained to ensure that its movement direction is straight and does not deviate or rotate, thus providing precise guidance for subsequent locking and releasing actions.

[0032] like Figure 3 As shown, the two ends of the compression spring 206 abut against the outer wall of the snap-fit ​​member 205 and the inner wall of the drive shaft 2, respectively.

[0033] The two ends of the compression spring 206 abut against the inner wall of the drive shaft 2 and the outer wall of the snap-fit ​​member 205, respectively. Under normal conditions, the spring is in a compressed state and continuously applies a pushing force to the snap-fit ​​member 205, forcing it to extend outward.

[0034] like Figure 2 and Figure 3 As shown, the outer wall of the snap-fit ​​component 205 is tightly fitted to the inner wall of the snap-fit ​​groove 101 opened inside the wheel 1. The bottom surface of the snap-fit ​​component 205 is a planar structure, and one side of the outer wall of the snap-fit ​​component 205 is snapped and connected to the inner wall of the snap-fit ​​groove 101. The center of the bottom surface of the wheel 1 abuts against the bottom outer wall of the drive shaft 2.

[0035] The thrust of the compression spring 206 can press the outer end of the snap-fit ​​member 205 tightly into the snap-fit ​​groove 101 inside the wheel 1. The bottom surface of the snap-fit ​​member 205 is flat, and one side of its outer wall is firmly engaged with the inner wall of the snap-fit ​​groove 101, forming a constraint on the axial movement of the wheel 1. At the same time, the center of the bottom surface of the wheel 1 contacts the bottom outer wall of the drive shaft 2, providing support and further restricting the relative position of the wheel 1 on the outer wall of the drive shaft 2.

[0036] like Figure 3 As shown, a groove 207 is provided on the top of the inner wall of the drive shaft 2, and the top of the inner wall of the groove 207 is in contact with the top surface of the limiting ring 203. The outer wall of the limiting ring 203 is slidably connected to the top of the inner wall of the groove 207.

[0037] The limiting ring 203 is embedded in the slide groove 207. The top of the slide groove 207 restricts the upward movement range of the limiting ring 203 to prevent it from accidentally falling off.

[0038] like Figure 1 As shown, a sloping surface is provided on one side of the outer wall of the snap-fit ​​component 205, and the sloping surface provided on the outer wall of the snap-fit ​​component 205 is in close contact with the bottom outer wall of the release button 202.

[0039] The top surface of the snap-fit ​​component 205 is provided with a sloping surface near the snap-fit ​​groove 101. The bottom outer wall of the release button 202 is in close contact with this sloping surface. When the release button 202 is pressed down, its bottom end will slide with the sloping surface, thereby pushing the snap-fit ​​component 205 to retract inward and release the snap-fit ​​state.

[0040] Working principle: The width of the rectangular groove 102 on the inner wall of the wheel 1 precisely matches the width of the protrusion 201 on the outer wall of the drive shaft 2. The top of the protrusion 201 is designed to be arc-shaped, and its two sides can slide smoothly along the inner wall of the rectangular groove 102, realizing the initial positioning and radial limiting function of the wheel 1 and the drive shaft 2. The slide rail 204 passes through the locking member 205, which can be displaced on the outer wall of the slide rail 204. The movement trajectory of the locking member 205 is constrained to ensure that its movement direction is straight and does not deviate or rotate, providing precise guidance for subsequent locking and releasing actions. The two ends of the compression spring 206 abut against the inner wall of the drive shaft 2 and the outer wall of the locking member 205, respectively. Under normal conditions, the spring is in a compressed state, continuously applying a pushing force to the locking member 205, forcing it to extend outward. The pushing force of the compression spring 206 can make the locking member... The outer end of the locking member 205 is tightly pressed into the locking groove 101 inside the wheel 1, and the bottom surface of the locking member 205 is flat. One side of its outer wall is firmly locked with the inner wall of the locking groove 101, forming a constraint on the axial movement of the wheel 1. At the same time, the center of the bottom surface of the wheel 1 contacts the bottom outer wall of the drive shaft 2, providing support and further limiting the relative position of the wheel 1 on the outer wall of the drive shaft 2. The limiting ring 203 is embedded in the slide groove 207. The top of the slide groove 207 limits the upward movement range of the limiting ring 203 to prevent it from accidentally falling off. The top surface of the locking member 205 has a sloping slope on the side near the locking groove 101. The bottom outer wall of the release button 202 is just in close contact with this sloping slope. When the release button 202 is pressed down, its bottom end will slide with the sloping slope, thereby pushing the locking member 205 to retract inward and release the locking state.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
