Description

Technical Field

[0001] The utility model relates to the technical field of fan regulators, in particular to a regulating device for an axial flow fan. Background Art

[0002] Axial flow fans are fans whose airflow is in the same direction as the axis of the fan blades. They are usually used in situations where the flow rate is high but the pressure is low, such as electric fans and air conditioner outdoor fans. The regulating device of axial flow fans is generally a fan speed regulator.

[0003] The common regulating devices for axial fans currently on the market are mostly similar in structure. They are mainly made of engineering plastic shells with circuit boards installed inside. The outside of the main shell generally has several main components, such as a voltage adjustment knob, a power input switch, an input socket, and an output power indicator light. There are some functional deficiencies in actual use and there is room for improvement. For example, the wiring used by the regulator to connect to the power supply is generally long, and needs to be bundled by yourself during daily storage. There is still droop after bundling, and it is not convenient to wind the wires. Secondly, since the regulator needs to adjust the voltage, its own temperature will rise significantly during operation. When the temperature exceeds a certain threshold, the probability of the circuit board burning will increase, and the operator cannot judge intuitively from the outside, and it does not have the function of conveniently monitoring the internal temperature. In addition, the regulating device of the axial fan is generally installed on the wall or the base of the fan. During installation, the installer needs to hold it with one hand and screw it in with the other hand. It is not convenient to operate and does not have the function of self-adhesion and auxiliary installation.

[0004] Now, a novel regulating device for an axial flow fan is proposed to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a regulating device for an axial flow fan to solve the problem that the aforementioned background technology does not have the function of facilitating the winding of wires.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustment device for an axial flow fan, comprising a shell, a voltage adjustment knob is arranged at the middle position of one side of the front end of the shell, a power input switch is arranged at the bottom of one side of the front end of the shell, an output socket is arranged at the bottom of the other side of the front end of the shell, an output power-on indicator light is fixedly connected to the top of the other side of the front end of the shell, side mounting plates are fixedly connected to the rear ends of both sides of the shell, an input power line is arranged on one side of the top of the shell, a liquid crystal display is fixedly connected to the top of one side of the front end of the shell, an infrared temperature sensor is installed at the rear end of the liquid crystal display, the rear end of the side mounting plate is evenly coated with a self-adhesive sticker, the rear end of the self-adhesive sticker is applied with release paper, and a wire winding structure is arranged at the bottom of the shell.

[0007] The structure for facilitating the winding of wires comprises a fixing plate, which is fixedly connected to the bottom of the shell, and two sides of the bottom of the fixing plate are respectively fixedly connected with square hooks, and the inner side surfaces of the square hooks are glued with rubber pads.

[0008] Preferably, the fixing plate and the square hook are made of the same material.

[0009] Preferably, the square hooks are symmetrically distributed about a vertical center line of the shell.

[0010] Preferably, the liquid crystal display screen and the infrared temperature sensor are electrically connected.

[0011] Preferably, the rear end of the infrared temperature sensor passes through the front end of the shell and extends into the interior.

[0012] Preferably, the side mounting plate and the release paper have consistent shapes and sizes.

[0013] Compared with the prior art, the beneficial effects of the utility model are: the regulating device for the axial flow fan not only realizes the function of facilitating the winding of the wire and the monitoring of the internal temperature, but also realizes the function of self-adhesion and auxiliary installation;

[0014] (1) By providing a fixing plate, a square hook and a rubber cushion, when in use, the input power cord is plugged into the power supply, the power cord of the axial flow fan is plugged into the output socket, the power input switch is turned on, and the output power indicator light is on, indicating that the power is connected, and the axial flow fan starts to work. When the fan power needs to be adjusted, it is only necessary to turn the voltage adjustment knob to adjust it. In the daily idle stage, the input power cord is directly wound along the square hook at the bottom of the fixing plate. The square hook can make the input power cord flexibly wound without falling. The rubber cushion can soften the contact surface between the square hook and the input power cord, reduce the wear on the wire, and realize the function of facilitating the winding of the wire;

[0015] (2) By providing a liquid crystal display and an infrared temperature sensor, when the regulating device is in use, the temperature of the circuit elements inside the housing will rise significantly. The infrared temperature sensor monitors the temperature of the circuit board below and feeds back the temperature value through the liquid crystal display, which is convenient for the user to observe and refer to. When the temperature is found to be too high, the power can be turned off in time for inspection, thereby realizing the function of conveniently monitoring the internal temperature;

[0016] (3) By providing the self-adhesive sticker and the release paper, when using, when installing the adjustment device, according to the actual situation of the installation location, the self-adhesive sticker can be selected for auxiliary installation. The release paper outside the self-adhesive sticker is torn off, and then the side mounting plate with the self-adhesive sticker is placed close to the installation location and pressed for one to five seconds to complete the initial fixation. The installer can then free his hands to drive in the screws, thus realizing the function of self-adhesion auxiliary installation. BRIEF DESCRIPTION OF THE DRAWINGS
