Description

Technical Field

[0001] This utility model relates to the field of air source heat pump hot air blower technology, and in particular to a noise reduction fan base vibration damping device for air source heat pump hot air blowers. Background Technology

[0002] Hot air blowers are widely used in industrial production, such as electronics, food, pharmaceuticals, printing and packaging. However, hot air blowers generate significant vibrations during operation. These vibrations not only affect the lifespan and operational stability of the equipment itself, but are also transmitted to the surrounding environment through the base.

[0003] Existing hot air blowers consist of components such as a motor, fan, fan shroud, fan impeller, radiator, and temperature controller. However, during operation, the motor drives the fan impeller, causing the fan to rotate rapidly and generate self-excited vibrations in the airflow. This can lead to a sudden increase in airflow disturbance and machine vibration. The severe vibrations generate noise, affecting the surrounding living and working environment.

[0004] To address these issues, we propose a noise reduction and vibration damping device for the base of an air source heat pump hot air blower. Utility Model Content

[0012] Preferably, the surface of the desiccant box is symmetrically hinged with fixing buckles, and the fixing buckles are installed above the through groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This device is equipped with a connecting rod that drives the fixed cover to rotate inside the U-shaped block. When the threaded nail is used to limit the fan body, the fixed cover covers the surface of the threaded nail to protect it, reduce the contact between the threaded nail and the air, slow down the oxidation and corrosion rate, prevent loosening, and improve the service life of the threaded nail. At the same time, the fixed block drives the telescopic rod to insert into the groove opened on the surface of the fixed support plate, so that the fixed sleeve can be locked onto the surface of the fixed shaft, which facilitates the function of limiting the fixed cover.

[0014] 2. The device is equipped with a desiccant box that is fixedly installed on the upper part of the fixed cover. The surface of the desiccant box has a through groove corresponding to the size of the placement plate.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-6 A noise reduction and vibration damping device for an air source heat pump hot air blower base includes: a fan vibration damping device 4, the upper end of which is connected to the fan body 1 via a fixed support plate 2, which facilitates vibration damping during operation of the hot air blower, preventing shaking and swaying that could affect the surrounding environment; U-shaped blocks 21 are connected to both sides of the surface of the fixed support plate 2, and the main body of the U-shaped blocks 21 is U-shaped, with connecting rods 22 installed inside the U-shaped blocks 21; the connecting rods 22 are made of plastic to prevent them from being exposed and to prevent rusting over time; a fixed shaft 23 is fixedly connected to the end of the connecting rod 22, and a fixed sleeve 24 is engaged with the surface of the fixed shaft 23 to limit the movement of the fixed shaft 23 and prevent accidental impact that could damage the fixed cover. The movement of the 26 sleeve cannot effectively protect the threaded nail 27. The lower end of the fixed sleeve 24 is connected to the telescopic sleeve 25, and a groove is opened on one side of the telescopic sleeve 25. Inside the groove, the telescopic rod 251 is driven to slide up and down through the fixed block 252, which facilitates manual operation and adjustment of the locking action. The surface of the fixed support plate 2 has a groove, which allows the telescopic sleeve 25 to lock in place, preventing the fixed sleeve 24 from falling off. The surface of the connecting rod 22 is fitted with a fixed cover 26, which effectively protects the threaded nail 27 from shaking and vibration during operation, preventing the threaded nail 27 from loosening and falling off. The upper end of the fixed cover 26 is fixedly connected to a dehumidifying box 3 to prevent the threaded nail 27 from encountering a humid environment during long-term use, thus preventing the threaded nail 27 from rusting and providing a certain degree of moisture protection.

[0021] Furthermore, refer to Figure 1 and Figure 2It can be seen that the surface of the fixed support plate 2 has four sets of holes and slots, and threaded nails 27 are installed inside the holes and slots. The hot air blower body is connected by mounting ears, and the threaded nails 27 are installed in the screw holes opened on the surface of the fixed support plate 2 through the mounting ears to fix the hot air blower body and prevent shaking and noise during operation. A rubber ring 28 is fitted on the surface of the threaded nails 27 to effectively fix the threaded nails 27 and prevent violent shaking and vibration during operation, which could cause the threaded nails 27 to loosen and fall off.

[0022] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the main body of the U-shaped block 21 is set in a U-shape, the connecting rod 22 is set in a plastic tube, the cross section of the fixed shaft 23 is set in a rectangular block, and the inside of the fixed sleeve 24 is provided with a rectangular groove that matches the fixed shaft 23. The fixed sleeve 24 is fitted on the surface of the fixed shaft 23 to play a certain role in limiting and fixing the shaft 23, so that the fixed cover 26 can prevent shaking during the working process and affect the effect of protecting the threaded nail 27.

[0023] Furthermore, refer to Figure 4 and Figure 6 It can be seen that the lower end of the fixed sleeve 24 is fixedly connected to the telescopic sleeve 25, and the upper end of the telescopic sleeve 25 is provided with a sliding groove. The telescopic rod 251 is installed inside the sliding groove. The side of the telescopic sleeve 25 is provided with a sliding groove, and the fixed block 252 is installed inside the sliding groove to drive the telescopic rod 251 to slide. This makes it easy to pick up the fixed block 252 and move it up and down, which facilitates effective telescopic extension and contraction and plays a certain locking role, making it easy to pick up. In addition, a groove is provided on the surface of the fixed support plate 2. The telescopic rod 251 inside the telescopic sleeve 25 abuts against the inside of the groove. Through the locking role, the fixed sleeve 24 is prevented from falling off and the staff is prevented from accidentally touching the internal fixed shaft 23.

[0024] Furthermore, refer to Figure 1 and Figure 5 It can be seen that the outer side of the desiccant box 3 has a through groove that matches the placement plate 31, which facilitates the effective pushing and pulling of the placement plate 31 inside and prevents jamming. Secondly, it is convenient to replace the desiccant that has been used for a long time and avoid the desiccant from becoming ineffective. The inner wall of the placement plate 31 has dense through holes, which facilitates the placement of the desiccant inside. The dense through holes also prevent moisture from the threaded nail 27 at the lower end and prevent the threaded nail 27 from rusting. The outer surface of the placement plate 31 is provided with rectangular blocks to facilitate the pushing and pulling of the placement plate 31 back and forth. The surface of the desiccant box 3 is symmetrically hinged with fixing buckles 32. The fixing buckles 32 are installed above the through groove and serve to fix the placement plate 31, so as to prevent the placement plate 31 from slipping due to tilting during the operation of the fixing cover 26.

[0025] Working Principle: In use, the operator starts the fan body 1, which is fixedly mounted on the surface of the fixed support plate 2. A fan vibration damping device 4 is installed at the lower end of the fixed support plate 2. A rubber ring 28 is fitted onto the surface of a threaded nail 27, which passes through a mounting lug at the bottom of the fan body and connects to a screw hole on the surface of the fixed support plate 2. This limits the fan body 1 to the surface of the fixed support plate 2. When placing a desiccant bag, the two sets of fixing buckles 32 are moved away from the side of the placement plate 31, allowing the placement plate 31 to be pulled out from inside the desiccant box 3, thus enabling the desiccant bag to be placed on the placement plate. Inside 31, the placement plate 31 is inserted into the desiccant box 3 to facilitate the carrying and separation of the desiccant pack. At this time, the fixing buckle 32 is moved so that it rotates to abut against the side of the placement plate 31, which facilitates the positioning of the placement plate 31. Then, the fixing cover 26 is moved so that the fixing cover 26 can drive the connecting rod 22 to rotate inside the U-shaped block 21. When the fixing cover 26 covers the surface of the threaded nail 27, the fixing sleeve 24 is fitted onto the surface of the fixing shaft 23. The fixing block 252 is pulled so that the telescopic rod 251 can extend out from inside the telescopic sleeve 25 and be inserted into the groove, which limits the fixing sleeve 24 and keeps the fixing cover 26 covering the surface of the threaded nail 27.

[0026] The above is the complete working principle of this utility model.

[0027] In this utility model, the installation, connection or setting methods of all the components mentioned above are common mechanical methods, and the specific structure, model and coefficient index of all the components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.
