Description

Technical Field

[0001] This utility model relates to the technical field of impeller disassembly equipment, and in particular to an impeller disassembly device for a range hood. Background Technology

[0002] In the field of range hood maintenance, impeller disassembly is an important and frequent operation. However, traditional disassembly tools generally suffer from inefficiency, complex operation, and poor user experience. These tools often require users to have high operating skills and spend a lot of time and effort to complete the disassembly task. This not only increases the user's labor intensity but may also lead to equipment damage or personal injury due to improper operation.

[0003] Specifically, traditional disassembly tools typically employ manual or simple mechanical methods, lacking intelligent and automated design. Users must repeatedly adjust the tool's position and angle during disassembly to accommodate impellers of different sizes and shapes. This not only increases operational complexity but can also lead to inefficient disassembly, failing to meet the needs of rapid maintenance.

[0004] Furthermore, traditional disassembly tools have shortcomings in design and material selection. Some tools are poorly designed, making them prone to wobbling or deviation during disassembly, affecting accuracy and safety. At the same time, some materials lack sufficient wear resistance and durability, causing the tools to easily break down after a period of use, increasing maintenance costs and usage risks.

[0005] Furthermore, the stability and reliability of disassembly tools are crucial factors in ensuring maintenance efficiency and safety during range hood maintenance. However, existing disassembly tools generally suffer from insufficient stability and reliability, severely impacting the smooth progress of maintenance work. On one hand, some disassembly tools are poorly designed, leading to shaking or deviation during use. This not only affects the accuracy of disassembly but may also pose potential safety threats to equipment and users. On the other hand, some tools suffer from inadequate material selection and manufacturing processes, resulting in poor wear resistance and durability. These tools are prone to wear, deformation, or damage after a period of use, reducing maintenance efficiency and lifespan. In addition, existing disassembly tools lack intelligent and automated features. Users need to manually adjust the position and angle of the tools during disassembly to accommodate impellers of different sizes and shapes. This not only increases the complexity of operation but may also lead to low disassembly efficiency and the risk of misoperation. Therefore, we provide an impeller disassembly device for range hoods. Utility Model Content

[0006] To address the aforementioned problems, this utility model proposes an impeller disassembly device for range hoods, which more accurately solves the problems mentioned in the background art.

[0007] This utility model is achieved through the following technical solution:

[0008] The utility model proposes an impeller disassembly device for a range hood, including a disc and a lever fixedly installed at the center of the disc surface. An opening groove is provided on the outer periphery of the disc, and a hook rod is rotatably connected to the opening groove via a rotating shaft. An unfolding structure is connected between the hook rod and the lever.

[0009] The unfolding structure includes a sleeve seat fitted around the pull rod. The upper end of the hook rod has an opening groove two. The outer periphery of the sleeve seat has an opening groove three. The opening groove three is rotatably connected to a rotating connecting rod via a rotating shaft. One end of the rotating connecting rod is rotatably connected to the opening groove two via a rotating shaft. The outer periphery of the pull rod is fitted with a spring one. The outer periphery of the pull rod is fixedly connected with a gripping rod. The upper periphery of the pull rod is connected with a pushing component for pushing the sleeve seat.

[0010] Furthermore, the pushing component includes a sleeve cap fitted around the upper periphery of the pulling rod, and the sleeve cap has a vertically formed groove on its periphery to avoid the gripping rod during the downward movement of the sleeve cap. A reciprocating assembly is connected between the pulling rod and the sleeve cap.

[0011] Furthermore, the reciprocating assembly includes a strip-shaped mounting groove vertically formed around the pull rod, with a retaining rod fixedly connected between the two end walls of the strip-shaped mounting groove, a spring being sleeved around the retaining rod, and a sliding sleeve block being slidably sleeved around the retaining rod.

[0012] Furthermore, the sliding sleeve is slidably connected to the inner wall of the strip-shaped mounting groove, and its outer periphery is fixedly connected to the inner wall of the sleeve cap.

[0013] Furthermore, the upper end of the first spring is fixedly connected to the lower end surface of the socket, and the lower end of the first spring is fixedly connected to the upper end surface of the disc.

[0014] Furthermore, the upper end of the second spring is fixedly connected to the lower end surface of the sliding sleeve block, and the lower end of the second spring is fixedly connected to the end wall of the strip-shaped mounting groove.

[0015] The beneficial effects of this utility model are:

[0016] This invention features a designed impeller disassembly device for range hoods. Users can easily control the opening and closing of the hook rod by simply gripping the pull rod and the sleeve cap.

[0022] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0023] Example

[0024] like Figures 1-3As shown, an embodiment of this utility model discloses an impeller disassembly device for a range hood, mainly composed of a disc 1 and a lever 4 fixedly installed at the center of the surface of the disc 1. The disc 1 has an opening groove 2 on its outer periphery, which is connected to a hook rod 3 via a rotating shaft, allowing the hook rod 3 to rotate around the rotating shaft. The lever 4 and the hook rod 3 are connected by an innovative unfolding structure. This unfolding structure includes a sleeve 5, which is fitted around the outer periphery of the lever 4. The upper end of the hook rod 3 has an opening groove 6, while the outer periphery of the sleeve 5 has an opening groove 7. The opening groove 7 is connected to one end of a rotating connecting rod 8 via a rotating shaft, and the other end of the rotating connecting rod 8 is connected to the opening groove 6 via a rotating shaft. This design allows the hook rod 3 to unfold or close by rotating the connecting rod 8 when the lever 4 is operated. Furthermore, a spring 9 is fitted around the outer periphery of the lever 4 to provide a restoring force. A lever 10 is also fixedly connected to the periphery of the lever 4 for user convenience. A pushing component is also designed on the upper periphery of the lever 4 to further control the movement of the socket 5; with this design, users can easily control the opening and closing of the hook rod 3 by holding the lever 10 and the pushing component, thereby realizing the disassembly of the range hood impeller.

[0025] Furthermore, the pushing component includes a socket cap 11, which is fitted onto the upper periphery of the pulling rod 4. A vertically oriented slot 12 is formed on the periphery of the socket cap 11. This slot 12 is designed to avoid interference between the socket cap 11 and the lever 10 during its downward movement. The pulling rod 4 and the socket cap 11 are connected by a reciprocating assembly, allowing the socket cap 11 to reciprocate up and down along the pulling rod 4.

[0026] The design of the socket cap 11 and the strip groove 12 allows the user to easily operate the socket cap 11 to move up and down without interfering with the gripping rod 10, thereby further controlling the opening and closing of the grab hook rod 3 through the reciprocating assembly.

[0027] Furthermore, the reciprocating assembly includes a vertically formed strip-shaped mounting groove 13 around the actuating rod 4, with a retaining rod 14 fixedly connected between the two end walls of the strip-shaped mounting groove 13. A spring 15 is sleeved around the retaining rod 14 to provide a restoring force. Simultaneously, a sliding sleeve 16 is slidably fitted around the retaining rod 14, and this sliding sleeve 16 can slide along the inner wall of the strip-shaped mounting groove 13.

[0028] When the socket cap 11 is pushed downward, the sliding block 16 slides down along the upright rod 14 and compresses the second spring 15. When the external force disappears, the restoring force of the second spring 15 pushes the sliding block 16 and the socket cap 11 upward, thereby realizing the reciprocating motion of the socket cap 11.

[0029] Furthermore, the sliding sleeve 16 is slidably connected to the inner wall of the strip-shaped mounting groove 13, ensuring that the sliding sleeve 16 can slide stably along the upright rod 14. At the same time, the outer periphery of the sliding sleeve 16 is fixedly connected to the inner wall of the socket cap 11, so that when the sliding sleeve 16 slides on the upright rod 14, the socket cap 11 will also move accordingly; this design ensures synchronous movement between the socket cap 11 and the sliding sleeve 16, thereby achieving precise control of the grab hook rod 3.

[0030] Furthermore, the upper end of spring 9 is fixedly connected to the lower end surface of the socket 5, while the lower end is fixedly connected to the upper end surface of the disk 1. This design ensures that when the socket 5 is pushed, spring 9 is compressed and provides a restoring force.

[0031] When an external force is applied to the socket 5, the spring 9 is compressed and stores energy. When the external force disappears, the restoring force of the spring 9 pushes the socket 5 back to its initial position, thereby achieving the reset control of the hook rod 3.

[0032] Furthermore, the upper end of the second spring 15 is fixedly connected to the lower end surface of the sliding sleeve 16, while the lower end is fixedly connected to the end wall of the strip-shaped mounting groove 13. This design ensures that when the sliding sleeve 16 is pushed, the second spring 15 is compressed and provides a restoring force.

[0033] When an external force is applied to the sliding sleeve 16, the second spring 15 is compressed and stores energy. When the external force disappears, the restoring force of the second spring 15 pushes the sliding sleeve 16 and the sleeve cap 11 upward, thereby achieving precise control of the grab hook rod 3. This design ensures the stability and reliability of the disassembly device.
