Description

Technical Field

[0001] This utility model relates to the field of heating technology, specifically a heating terminal temperature regulation device. Background Technology

[0002] Heating refers to providing heat to the interior of a building to maintain a certain indoor temperature. It is a social service that addresses the basic heating needs of residents in northern my country during winter. In urban areas of my country, there are two main types of heating: electric heating and water heating. Electric heating can be provided through air conditioning or by using electric radiators, while water heating is mainly provided by municipal heating companies. Electric heaters, also known as electric space heaters, are used for terminal heating. They are primarily used in the cold winters of northern regions to provide indoor heating and are widely used in residences, offices, hotels, shopping malls, hospitals, schools, and other public places. To ensure the cleanliness of the air output and the interior of the heater, a filter is usually installed at the air inlet at the bottom of the heater to filter external impurities. However, these filters are mostly installed inside the casing, requiring the casing to be disassembled for replacement, which is inconvenient. Therefore, we propose a temperature regulation device for the heating terminal. Utility Model Content

[0020] Please see Figure 1-3 This embodiment provides a technical solution: a heating terminal temperature regulating device, including a housing 1 and a filter assembly 5;

[0021] Outer casing 1: A PLC controller 12 is installed on the left side. An axial flow fan 2 and an electric heating plate 3 are installed inside the outer casing 1.

A cleaning component 6 is installed at the lower end inside the outer casing 1. The cleaning component 6 includes a rotating shaft 61 and brush bristles 62. The rotating shaft 61 is rotatably connected to the left end inside the outer casing 1. Evenly distributed brush bristles 62 are fixed on the circumferential surface of the rotating shaft 61. All the brush bristles 62 on the upper side are in contact with the lower side of the filter screen 52. The fixing component 7 includes a fixing strip 71, a locking rod 72, a connecting strip 73, a limiting ring 74, and a spring 75. The fixing strip 71 is fixed on the left side of the outer casing 1. Two corresponding sliding holes are opened on the upper side of the fixing strip 71. The sliding holes are slidably connected to the inner side of the fixing strip 71. The two clamping rods 72 have their lower ends respectively engaged in the interior of the two clamping holes 54. The upper ends of the two clamping rods 72 are fixed with connecting strips 73. Limiting rings 74 are fixed on the circumferential surface of the clamping rods 72. Both limiting rings 74 are in contact with the upper side of the limiting plate 53. Springs 75 are sleeved on the circumferential surface of the clamping rods 72. The lower end of the springs 75 is fixed to the upper end of the limiting rings 74, and the upper end of the springs 75 is fixed to the lower side of the fixing strip 71. The adsorption assembly 8 includes an iron plate 81 and a magnet 82. An iron plate 81 is fixed on the left side of the outer shell 1. A groove is opened on the upper side of the connecting strip 73. A magnet 82 is fixed inside the groove. The magnet 82 corresponds to the iron plate 81. The adsorption assembly 8 is set to facilitate the fixing of the connecting strip 73 during disassembly. The fixing assembly 7 is set to fix the limiting plate 53. The cleaning assembly 6 is set to clean the mesh surface of the filter screen 52 during disassembly.

[0022] Filter assembly 5 includes a sliding frame 51, a filter screen 52, a limiting plate 53, and a locking hole 54. A sliding groove is provided at the lower left side of the outer casing 1. The sliding frame 51 is connected inside the sliding groove. The filter screen 52 is fixed inside the lower side of the sliding frame 51. The limiting plate 53 is fixed on the left side of the sliding frame 51. Two corresponding locking holes 54 are provided on the upper side of the limiting plate 53. The lower end of the fixing assembly 7 is connected to the two locking holes 54. The cleaning assembly 6 is attached to the lower side of the filter screen 52. The air entering the outer casing 1 is filtered by setting the filter assembly 5.

[0023] Wherein: the input terminal of PLC controller 12 is electrically connected to the output terminal of external power supply, and the output terminal of PLC controller 12 is electrically connected to the input terminals of axial flow fan 2 and electric heating plate 3 respectively.

[0024] Among them, the front and rear ends of the lower side inside the outer shell 1 are rotatably connected with evenly distributed guide wheels 9. All guide wheels 9 are in contact with the lower side of the slide frame 51, and the slide frame 51 is guided by the guide wheels 9.

[0025] The outer shell 1 has four corresponding support legs 10 fixed on its lower side, and a base plate 11 is fixed on the lower side of the four support legs 10. The outer shell 1 is supported by the support legs 10 and the base plate 11.

[0026] The working principle of the heating terminal temperature regulation device provided by this utility model is as follows: The device achieves heating through the coordinated operation of the axial flow fan 2 and the electric heating plate 3 inside the outer shell 1. External air first enters from the lower end of the outer shell 1 and passes through the filter screen 52 of the filter assembly 5 to filter impurities, ensuring that the incoming air is clean. Subsequently, the axial flow fan 2 blows the filtered air upward to the electric heating plate 3, which heats the air. The heated air is discharged through the evenly distributed air outlets 4 at the upper front end of the outer shell 1, thereby providing uniform hot air to the room. When the filter screen 52 needs to be cleaned or replaced, the device can be easily disassembled through the fixing assembly 7 and the adsorption assembly 8. First, pull the connecting strip 73 of the fixing assembly 7 upward to disengage the locking rod 72 from the locking hole 54 of the filter assembly 5; at this time, the spring 75 is compressed. Deformation occurs as the limiting ring 74 moves upward with the locking rod 72, releasing the fixation on the limiting plate 53. The magnet 82 of the adsorption component 8 attracts the iron plate 81. During disassembly, the connecting strip 73 is fixed to prevent accidental slippage. Subsequently, the sliding frame 51 is pulled outward, and the sliding frame 51 in the slide groove drives the filter screen 52 out of the outer shell 1. During this process, the cleaning component 6 works automatically: the rotating shaft 61 rotates inside the outer shell 1, and the bristles 62 on its circumferential surface are tightly attached to the lower side of the filter screen 52. The bristles 62 rotate with the movement of the filter screen 52, removing the impurities accumulated on the screen. After cleaning, the sliding frame 51 is pushed back in, and the locking rod 72 automatically engages with the locking hole 54 under the restoring force of the spring 75. The limiting plate 53 is re-fixed, and the device can be restored to normal use. The support leg 10 and the base plate 11 support the entire outer shell 1 to ensure stability during the disassembly process.

[0027] It is worth noting that the PLC controller 12 disclosed in the above embodiments is specifically a Siemens S7-200. The axial flow fan 2 and the electric heating plate 3 can be freely configured according to the actual application scenario. The PLC controller 12 controls the operation of the axial flow fan 2 and the electric heating plate 3 using methods commonly used in the prior art.
