[0009] Furthermore, the air inlets are located on both sides of the device housing.

[0010] Compared to existing technologies, the advantages of this invention are as follows: Through its structural design, when a hot air blower is needed, first unlock the angle adjustment devices at both ends of the support rod and pull the outer casing outwards. The outer casing moves outwards from the storage base, causing the support rod to move. The moving support rod pulls the sliding seat to slide within the groove. When the outer casing is completely removed from the storage base, the sliding seat slides to the leftmost end of the groove. At this point, a spring pushes the locking block into the grooves on both sides of the sliding seat, limiting its position. Then, rotate the outer casing, align the air outlet with the desired location, and lock the angle adjustment devices at both ends of the support rod. The fan and heating element are then activated, and the fan directs the heat from the heating element... The air is released from the air outlet. The air inlets on both sides of the device housing are located at the air inlets. When the device is no longer needed, the angle adjustment devices at both ends of the support rod are unlocked and the locking blocks are pulled so that the locking blocks are no longer inserted into the sliding base. At this time, the device housing is moved and inserted into the storage base. The angle adjustment devices are then locked to complete the storage and prepare for the next use. Compared with the prior art, the present invention can be folded, reducing the overall storage volume and making it convenient for users to store. At the same time, the air inlets and outlets are sealed to prevent dust and other particles from entering the device housing, extending the service life of the device and reducing the number of times the device needs to be cleaned due to long usage time.

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1-7 This utility model provides a technical solution: a foldable and retractable hot air blower, including a device housing 1, a fan 2, a heating element 3, an air inlet 4, an air outlet 5, an angle adjustment device 6, a support rod 7, a sliding seat 8, a storage base 9, a sliding groove 10, a locking block 11, and a spring 12. The device housing 1 is fixedly connected to the fan 2 and the heating element 3. The device housing 1 has an air inlet 4. The right side of the device housing 1 is connected to the air outlet 5 by bolts. The device housing 1 is fixedly connected to the angle adjustment device 6. Each side of the support rod 7 is fixedly connected to an angle adjustment device 6. The right angle adjustment device 6 of the support rod 7 is fixedly connected to the sliding seat 8. The storage base 9 has a sliding groove 10. The sliding seat 8 is slidably connected to the sliding groove 10. The device housing 1 is inserted into the storage base 9. Each storage base 9 is slidably connected to a locking block 11. The spring 12 is located inside the storage base 9 and is fixedly connected to the storage base 9 at one end. The other end of the spring 12 is fixedly connected to the locking block 11.

[0021] In this utility model, the angle adjustment device 6 includes a connecting seat 601, a circular groove 602, a limiting block 603, a rotating shaft 604, an internal toothed opening 605, and an external toothed opening 606. The connecting seat 601 has a circular groove 602. The limiting block 603 is located within the circular groove 602 and its end is slidably connected to the rotating shaft 604. The limiting block 603 has an internal toothed opening 605, and the circular groove 602 has an external toothed opening 606. The internal toothed opening 605 and the external toothed opening 606 engage. The rotating shaft 604 is rotatably connected to the connecting seat 601. The rotating shaft 604 is fixedly connected to the support rod 7. By pulling the limiting block 603 outward, the inner toothed mouth 605 and the outer toothed mouth 606 are separated. At this time, the support rod 7 can drive the rotating shaft 604 to rotate freely on the connecting seat 601, achieving the unlocked state. When it is necessary to lock the angle, press the limiting block 603 inward and press the limiting block 603 into the circular groove 602. At this time, the inner toothed mouth 605 and the outer toothed mouth 606 are engaged, and the limiting block 603 cannot rotate. The inability of the limiting block 603 to rotate prevents the rotating shaft 604 from rotating, thus completing the locking process.

[0022] In this utility model, the device housing 1 is provided with a handle 13, which is fixedly connected to the device housing 1. The handle 13 makes it easier for users to take the device housing 1 out of the storage base 9.

[0023] In this utility model, a soft pad 14 is provided inside the storage base 9. The soft pad 14 is fixedly connected to the storage base 9. The soft pad 14 inside the storage base 9 can prevent the device housing 1 from colliding with the storage base 9 when it is stored, which would cause damage to the air outlet 5.

[0024] In this invention, the air inlets 4 are located on both sides of the device housing 1. The air inlets 4 on both sides can be closed by the storage base 9 when the device housing 1 is stored in the storage base 9 to prevent dust from entering.

[0025] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0026] In this implementation scheme: When the hot air blower is needed, firstly, unlock the angle adjustment devices 6 at both ends of the support rod 7 and pull the outer casing 1 outward. By pulling the limiting block 603 outward, the internal toothed mouth 605 and the external toothed mouth 606 are separated. At this time, the support rod 7 can drive the rotating shaft 604 to rotate freely on the connecting seat 601, achieving the unlocked state. When the angle needs to be locked, press the limiting block 603 inward, pressing the limiting block 603 into the circular groove 602. At this time, the internal toothed mouth 605 and the external toothed mouth 606 are engaged, and the limiting block 603 cannot rotate. The inability of the limiting block 603 to rotate prevents the rotating shaft 604 from rotating, completing the locking process. The outer casing 1 moves outward from the storage base 9, driving the support rod 7 to move. The handle 13 on the outer casing 1 makes it easier for the user to remove the outer casing 1 from the storage base 9. The movement of the support rod 7 pulls the sliding seat 8 to slide in the slide groove 10. When the outer casing 1 is completely removed from the storage base 9... When the storage base 9 is removed, the sliding seat 8 slides to the leftmost end of the slide groove 10. At this time, the spring 12 pushes the locking block 11 to insert into the grooves on both sides of the sliding seat 8, limiting the sliding seat 8. Then, rotate the device housing 1, align the air outlet 5 with the required place, and lock the angle adjustment device 6 at both ends of the support rod 7. When in use, start the fan 2 and the heating element 3. The fan 2 releases the heat emitted by the heating element 3 from the air outlet 5. The air inlet of the device housing 1 is located at the air inlet 4 on both sides of the device housing. Finally, when the utility model is no longer needed, unlock the angle adjustment device 6 at both ends of the support rod 7 and pull the locking block 11 so that the locking block 11 is no longer inserted into the sliding seat 8. At this time, move the device housing 1, insert the device housing 1 into the storage base 9, and lock the angle adjustment device 6 to complete the storage and wait for the next use. The soft pad 14 in the storage base 9 can prevent the device housing 1 from colliding with the storage base 9 when it is stored again, which would damage the air outlet 5.
