Description

Technical Field

[0001] This utility model relates to the field of controller technology, and in particular to a compact controller. Background Technology

[0002] Compact controllers are suitable for 2-pipe or 4-pipe fan coil units, underfloor heating, and chilled beam applications. Depending on the model, they can control two-wire spring return valves, three-state floating point valves, or analog continuous control valves. Controllers are an indispensable component of automation systems. They receive input signals from sensors or other devices and generate corresponding output signals based on preset control strategies or algorithms, thereby achieving precise control of the controlled object. Controllers are widely used in industry, transportation, and home applications, improving system efficiency and stability, reducing energy waste, and enhancing safety and convenience. With technological advancements, the intelligence and networking of controllers will become important future development trends.

[0003] To address this, the patent specification with publication number CN202231880U discloses a highly integrated controller, which consists of a controller housing, connecting flexible wires, a power cord, a toggle switch, and a PCB circuit board. Its key features include two small holes on the controller housing, eight terminal pieces arranged in two parallel rows on the toggle switch, and the PCB circuit board consisting of eight through holes, four resistors, two LEDs, one diode, and one fuse. The controller housing and the toggle switch are assembled together, and the toggle switch is connected to the PCB circuit board through the through holes. This design solves the problems of poor contact, short lifespan, poor consistency, complex operation, and high cost associated with ordinary controllers, and is suitable for use in flexible heating appliances.

[0004] The aforementioned highly integrated controller solves the problems of poor contact, short lifespan, poor consistency, complex operation, and high cost of ordinary controllers. It is suitable for use in flexible heating appliances. However, dust may accumulate on the surface of the display screen during use, affecting its operation. Utility Model Content

[0005] The purpose of this invention is to provide a compact controller to address the shortcomings of existing compact controllers in that they are difficult to clean the display screen.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a compact controller, including a housing;

[0007] Side plates are installed on both sides of the housing, a fixing plate is installed on one side of the side plate, and a fixing screw is installed on one end of the fixing plate;

[0008] A button is installed at one end of the housing, a display screen is installed at one end of the housing, and a processor is installed inside the display screen;

[0009] A cleaning structure is installed at one end of the housing. The cleaning structure includes a mounting plate installed at one end of the housing, and a threaded rod is installed on the inner side of the mounting plate.

[0010] In use, the device can control other devices via buttons, the processor can process data, the display screen can display data, and the heat sink can be made of brass. The heat sink has a large surface area and high thermal conductivity, allowing it to absorb heat and then dissipate it quickly through its large surface area. The slot allows for an even larger surface area for the heat sink.

[0011] Furthermore, a protective structure is installed at one end of the housing. The protective structure includes a baffle installed at one end of the housing, and a rotating shaft installed on the inner side of the baffle. A connecting rod is installed at the bottom end of the rotating shaft, and a protective plate is installed at the bottom end of the connecting rod. The protective plate can protect the button.

[0012] Furthermore, the bottom end of the protective plate is provided with a locking block, and one end of the housing is provided with a locking groove. The protective plate and the housing form a locking structure, which facilitates disassembly.

[0013] Furthermore, a heat dissipation structure is installed at one end of the housing, and the heat dissipation structure includes a groove disposed at one end of the housing, and a heat sink is installed inside the groove, which can dissipate heat quickly.

[0014] Furthermore, a groove is provided at one end of the heat sink, and the grooves are arranged at equal intervals at one end of the heat sink, which can increase the surface area of ​​the heat sink.

[0015] Furthermore, the fixing screws are threadedly connected to the fixing plate, and the fixing screws are symmetrically distributed about the central axis of the housing, so that the device can be installed by fixing screws.

[0016] Furthermore, a screwing block is installed at the top of the threaded rod, a moving block is installed on the outside of the threaded rod, a cleaning brush is installed on one side of the moving block, and a guide rod is installed on one side of the cleaning brush. Rotation of the threaded rod will drive the cleaning brush to clean the display screen.

[0017] Furthermore, the outer side wall of the threaded rod is uniformly provided with external threads, and the inner side wall of the moving block is uniformly provided with internal threads that cooperate with the external threads. The threaded rod and the moving block are threadedly connected, and the rotation of the threaded rod will drive the moving block to rise and fall.

[0018] Furthermore, the outer diameter of the guide rod is smaller than the inner diameter of the cleaning brush, and the guide rod and the cleaning brush form a sliding structure, which can prevent the cleaning brush from deviating.

[0019] The compact controller provided by this utility model has the following advantages: during use, the surface of the display screen can be cleaned by raising and lowering the cleaning brush, which can prevent dust from adhering to the display screen during use. At the same time, the protective plate can protect the buttons to prevent accidental button presses, and the heat sink can dissipate heat from the device.

[0020] By installing a mounting plate at one end of the housing, the threaded rod inside the mounting plate can rotate. It can grip the screw block and drive the threaded rod to rotate. The rotation of the threaded rod will drive the moving block, which is threadedly connected to it, to rise and fall. The rising and falling of the moving block will drive the cleaning brush to rise and fall. The rising and falling of the cleaning brush can clean the surface of the display screen and prevent dust from adhering to the surface of the display screen. The cleaning brush and the guide rod form a sliding structure. The guide rod passes through the cleaning brush and can guide the cleaning brush to prevent the cleaning brush from deviating when rising and falling. This achieves the purpose of a compact controller to facilitate the cleaning of the display screen.

[0021] By installing a baffle at one end of the housing, the rotating shaft inside the baffle can rotate. The rotation of the rotating shaft will drive the connecting rod to rotate, and the rotation of the connecting rod will drive the protective plate to rotate. The rotating protective plate will cover the button surface, thus protecting the button and preventing accidental button presses. When the button needs to be used, rotate the protective plate so that it no longer covers the button surface, and the button can be used. This achieves the purpose of making the compact controller easy to protect the button. Attached Figure Description
