Description

Technical Field

[0001] This utility model relates to the field of food processing equipment, and in particular to a fan regulating device and a fan having the same. Background Technology

[0002] In turtle slaughtering workshops, the application of regulating fans is closely related to workshop environmental control, improving work efficiency, and ensuring product quality. Specifically, turtle slaughtering workshops typically need to maintain a relatively constant temperature and humidity environment. Regulating fans help regulate air circulation within the workshop, maintaining suitable temperature and humidity. This is crucial for the preservation of turtles, as excessively high temperatures or unsuitable humidity can easily affect the meat quality and processing. During slaughtering, a certain amount of blood, visceral residue, and other waste may be generated in the workshop. These substances can lead to air pollution and even the growth of harmful bacteria. Regulating fans help ensure sufficient ventilation within the workshop, reducing the accumulation of harmful gases, maintaining fresh air, and benefiting the health of workers and food safety.

[0003] However, existing regulating fans often encounter the following problems in use: Traditional fan settings typically have several discrete speeds, and the airflow can only be switched between a few fixed values. For example, common fans may have three speeds: low, medium, and high, and the airflow can only change between these three preset values. Continuous airflow adjustment is not possible. The inability to continuously adjust means that the airflow requirements of different times and processes in the turtle slaughtering workshop cannot be precisely met. The airflow directly affects the humidity level in the workshop. If the airflow cannot be precisely adjusted, the humidity in the workshop will be too high or too low, which will not only affect the quality of the turtles but may also breed bacteria and mold, increasing food safety risks. Utility Model Content

[0004] The main purpose of this utility model is to provide a fan regulating device and a fan having the same, so as to effectively solve the problem mentioned in the background art that the existing fans cannot achieve continuous air volume regulation. If the air volume cannot be finely regulated, it will lead to excessively high or low humidity in the workshop, which will affect the quality of the turtles.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A fan regulating device and a fan having the same, comprising:

[0007] The fan regulating device includes:

[0008] An extended air duct, one end of which is connected to the air outlet of the fan, and the other end of which extends in a direction away from the fan;

[0009] Multiple rotating shafts are rotatably mounted on the wall of the extended air duct.

[0010] Multiple adjusting blades are mounted one-to-one on multiple rotating shafts, and the multiple adjusting blades are configured to adjust the air volume of the extended air duct by rotating the multiple rotating shafts.

[0011] The fan regulating device further includes:

[0012] A deflection link, one end of which is sleeved onto one end of the rotating shaft;

[0013] A transmission ring is sleeved on the body of the extended air duct, and the transmission ring is movably connected to the other end of the turning link;

[0014] A positioning groove is formed in the body of the extended air duct, and the transmission ring is located in the positioning groove;

[0015] A booster link, the body of which is connected to the transmission ring;

[0016] The main push rod, the top end of which is connected to one end of the booster connecting rod;

[0017] A booster cylinder, the output end of which is connected to the bottom end of the main push rod;

[0018] Mounting base, which is horizontally mounted on the body of the extended air duct;

[0019] The central axis is fixedly installed at the central axis position of the air outlet.

[0020] One end of each of the multiple rotating shafts is movably connected to the central shaft.

[0021] The booster cylinder is mounted on the mounting base.

[0022] The mounting base is located below the booster linkage.

[0023] The booster link is arc-shaped.

[0024] A fan, the fan having the fan regulating device.

[0025] Compared with existing technologies, the beneficial effects of this invention are as follows: The airflow regulating device of this invention achieves airflow regulation by controlling the angle of the adjusting blades blocking the air outlet, thus enabling continuous airflow adjustment. Through continuous changes in the angles of multiple adjusting blades, the airflow can be finely adjusted within a large range, more accurately meeting the airflow requirements of different times and processes in the turtle slaughtering workshop. For example, in the turtle slaughtering workshop, certain special processes may only require very small adjustments to the airflow. Because this design can precisely control the blade angles, it is highly effective in fine-tuning the airflow. Attached Figure Description

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.

[0032] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] This utility model provides a fan regulating device for adjusting the airflow of a fan. For example... Figure 1-3 As shown, the fan regulating device provided by this utility model specifically includes: a fan 1, an extension duct 2, multiple rotating shafts 3, and multiple adjusting blades 4. The fan 1 is mounted on the ground and is the core component of the entire device, used to generate airflow. It is mounted on the ground and connected to the air outlet via the extension duct 2. The extension duct 2 is connected to the air outlet of the fan 1 and is used to guide and concentrate the airflow. An air outlet is opened at its top, allowing airflow to be discharged from here; air is transported from the fan 1 to the air outlet. One end of the extension duct 2 is connected to the air outlet of the fan 1, and the other end extends in a direction away from the fan 1. Multiple rotating shafts 3 are rotatably mounted on the wall of the extension duct, and multiple adjusting blades 4 are correspondingly installed on the multiple rotating shafts 3. The multiple adjusting blades 4 are configured to adjust the airflow of the extension duct 2 by rotating the multiple rotating shafts 3.

[0034] Multiple rotating shafts 3 are provided, which are arranged around the inner wall of the extension duct 2, with each rotating shaft 3 having a gap. Multiple adjusting blades 4 are fixed to the shafts of the multiple rotating shafts 3 in a corresponding manner. One end of the turning connecting rod 5 is sleeved on one end of the rotating shaft 3, and the transmission ring 6 is sleeved on the body of the extension duct 2. The transmission ring 6 is movably connected to the other end of the turning connecting rod 5. The positioning groove 7 is opened in the body of the extension duct 2, and the transmission ring 6 is located in the positioning groove 7. The body of the boosting connecting rod 8 is connected to the transmission ring 6. The boosting connecting rod 8 is arc-shaped. The top of the main push rod 9 is connected to one end of the boosting connecting rod 8, and the output end of the boosting cylinder 10 is connected to the bottom end of the main push rod 9. The boosting cylinder 10 is set on the mounting base 11, and the body of the boosting connecting rod 8 is connected to the transmission ring 6. It presents a unique arc shape. This arc shape is carefully designed according to the layout of the entire device and the force transmission path. The booster link 8 has a suitable length and degree of curvature. Its length is sufficient to ensure effective force transmission when connecting the transmission ring 6 and the main push rod 9, while its curvature must adapt to the spatial structure of the device to avoid interference with other components. The booster link 8 is made of a material with sufficient strength and toughness to withstand the tension and pressure during the rotation of the transmission ring 6. One end of it is connected to the top of the main push rod 9. This connection method must ensure efficient force transmission, allowing the pushing force of the main push rod 9 to be accurately transmitted to the booster link 8, thereby driving the transmission ring 6 to rotate axially. The mounting base 11 is horizontally mounted on the body of the extension duct 2, located below the booster link 8.

[0035] Fan 1, through its installed fan regulating device, controls the angle of the blades blocking the air outlet, thereby achieving the effect of regulating airflow. The airflow regulating device allows for continuous airflow adjustment. By continuously changing the angles of multiple regulating blades, the airflow can be finely adjusted within a large range, more accurately meeting the airflow requirements of different times and processes in the turtle slaughtering workshop. For example, in the turtle slaughtering workshop, certain special processes may only require very small adjustments to the airflow. This design, due to its ability to precisely control the blade angle, is remarkably effective in fine-tuning the airflow.

[0036] It should be noted that the fan adjustment device and the fan incorporating it designed in this utility model can be used by directly activating the booster cylinder 10. The output end of the booster cylinder 10 pops out, pushing the main push rod 9. The main push rod 9 pushes the booster connecting rod 8, which in turn drives the transmission ring 6 to rotate around the axis of the extended air duct 2. The transmission ring 6 drives all the turning connecting rods 5 of the ring body. One end of the turning connecting rod 5 is driven, which pulls the other end of the turning connecting rod 5 to rotate. The other end of all the turning connecting rods 5 will drag all the other ends of the ring body. Multiple rotating shafts 3 rotate around their respective axes, thereby driving the adjusting blades 4 to rotate at an angle. The more vertical the rotation of the multiple adjusting blades 4 becomes, the larger the gap between the blades, and the greater the air volume discharged from the outlet of the fan 1. Conversely, when the cylinder retracts, it will drive the above-mentioned components to rotate in the opposite direction, thereby causing the multiple adjusting blades 4 to rotate in the opposite direction and tend to be horizontal. The more horizontal the rotation of the multiple adjusting blades 4 becomes, the smaller the gap between the blades, and the smaller the air volume discharged from the outlet of the fan 1, until the outlet is completely blocked by the blades.

[0037] 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 may 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.
