Description

Technical Field

[0001] The utility model relates to the technical field of temperature controllers, in particular to a digital display temperature controller. Background Art

[0002] Temperature controller, also known as thermostat, produces physical deformation inside the switch according to the temperature change of the working environment, thereby producing certain special effects, a series of automatic control elements that produce conduction or disconnection actions, or electronic components at different temperatures, different working states to provide temperature data to the circuit. With the development of science and technology, temperature controllers are gradually applied to various aspects of life, such as display screens, household appliances, etc., and the existing display screen temperature controllers mostly use electronic temperature control. Although this method has more accurate temperature control, the power consumption will also increase accordingly. The traditional mechanical type is not sensitive to temperature, which often leads to incorrect temperature control. At this point, it is necessary to adopt a mechanical plus electronic temperature control form. The use of liquid expansion plus electronic temperature control can well avoid energy consumption and inaccurate temperature control.

[0003] After searching, the Chinese patent announcement number is CN215298036U, which discloses a touch screen temperature controller. In this patent, the body can be fixed on the body shell of the touch screen by squeezing the triangular stopper after installation, which greatly speeds up the installation efficiency of the body and changes the existing screw installation method. The triangular stopper and the control panel can be freely adjusted by screws, and by adjusting according to the scale line distance, it is convenient to match the thickness of the body shell of the touch screen after the hole is opened, and can be suitable for installation of body shells of different thicknesses;

[0004] However, in the process of use, in order to protect the internal components, most temperature controllers usually only have a small number of heat dissipation holes in some areas of the shell to dissipate the heat inside the temperature controller during operation. However, this method has a poor heat dissipation effect when the ambient temperature is too high. At the same time, the above-mentioned device requires the use of screws and other structures for the installation of the shell, and the installation method is complicated, which is not convenient for subsequent maintenance and disassembly. Utility Model Content

[0005] The utility model provides a digital display temperature controller, which has the advantages of rapid heat dissipation and rapid disassembly or installation, and solves the problems of failure to rapidly dissipate heat and cumbersome disassembly and installation in the related art.

[0006] The technical solution of the utility model is as follows: a digital display temperature controller comprises a main body, a device block is fixedly installed on the rear side of the main body, a fan is fixedly installed on the top of the device block, a shell is detachably installed on the outer surface of the main body, a slanted plate cover is fixedly installed on the top of the shell, a vent is opened on the top of the shell, a groove is opened on the rear side of the inner cavity of the vent, an electromagnet is fixedly installed on the rear side of the inner cavity of the groove, a plurality of springs are fixedly installed on the rear side of the inner cavity of the groove, a push plate is fixedly installed on the other side of the spring, a shield is fixedly installed on the front side of the push plate, a plug rod is fixedly installed on the front side of the bottom of the inner cavity of the shell, limiting holes are opened on the front sides of the left and right sides of the shell, and baffles are movably installed on the front sides of the left and right sides of the shell through rotating shafts.

[0007] Preferably, a slot is provided at the bottom of the main body, a through hole is provided in the middle of the bottom of the main body, a sealing plate is installed at the bottom of the through hole through rotation of a torsion shaft, strip grooves are provided on the left and right sides of the front side of the main body, a baffle rod is installed at the top of the inner cavity of the strip groove through rotation of a torsion shaft, and a rubber pad is fixedly installed at the bottom of the inner cavity of the strip groove.

[0008] Preferably, the vent is located at the bottom of the inner cavity of the inclined plate cover, and the inclined plate cover has an inverted triangle appearance, so that when in use, the inclined plate cover can be used to prevent external impurities from entering the vent.

[0009] Preferably, the rear side of the push plate has an opposite magnetic pole to the electromagnet after power is supplied, and the electromagnet is electrically connected to the fan on the top of the equipment block through a wire. Therefore, when in use, when the temperature of the inner cavity of the shell is too high, the equipment block controls the fan to start, and the fan and the electromagnet are electrically connected in series. When the fan starts, the electromagnet is energized, and then under the effect of opposite charges attract, the push plate moves backward, driving the shield plate to move backward, thereby increasing the area of ​​air flowing through the vent, thereby accelerating the heat dissipation.

[0010] Preferably, the baffle is located on one side of the limiting hole, and the shape of the baffle is larger than the shape of the cross section of the inner cavity of the limiting hole, so that when in use, the baffle is used to block the limiting hole to prevent external impurities from entering.

[0011] Preferably, the inner surface of the shell is made of rubber material, and the position, shape and number of the insertion rods match the position, shape and number of the slots, so that when in use, the shell can be quickly assembled with the main body through the insertion rods and the slots, and the rubber material on the inner surface of the shell can improve the sealing of the assembly after assembly.

[0012] Preferably, the through hole is located directly below the bottom socket of the equipment block, and the shape of the sealing plate is larger than the cross-section of the through hole, so that when in use, the sealing plate is used to block the through hole to prevent external impurities from entering the rear inner cavity of the main body through the through hole.

[0013] Preferably, the length of the baffle rod matches the sum of the depths of the inner cavity of the strip groove and the limiting hole, and the thickness of the rubber pad is greater than the distance between the baffle rod and the bottom of the inner cavity of the strip groove after the baffle rod is rotated to be perpendicular to the bottom of the inner cavity of the strip groove. Therefore, during use, in a normal state, the baffle rod is in a parallel state with the bottom of the inner cavity of the strip groove under the action of the torsion shaft. At this time, the baffle rod extends into the inner cavity of the limiting hole, so that the main body and the outer shell are effectively assembled. When the baffle rod is rotated and is perpendicular to the bottom of the inner cavity of the strip groove, the rubber pad is used to prevent the baffle rod from being flipped and reset in time.

[0014] The working principle and beneficial effects of the utility model are:

[0015] The digital display temperature controller is used in conjunction with a bar groove structure and a baffle structure. When working, the shell is quickly assembled with the main body from the rear side through the insertion rod and the slot. After the assembly, the baffle is in a parallel state with the bottom of the inner cavity of the bar groove under the action of the torsion shaft, that is, the baffle extends into the inner cavity of the limit hole after installation, and cooperates with the insertion rod to prevent the shell from being separated from the main body. When disassembly is required, the baffle is manually pushed to rotate to the inner cavity of the bar groove, so that the bottom of the baffle is in contact with the rubber pad, and the baffle cannot be flipped and reset in time. At this time, the main body can be quickly separated from the shell, so as to achieve the effect of rapid heat dissipation.

[0016] The digital display temperature controller is used through the cooperation of the push plate structure and the shield plate structure. During use, because the electromagnet is electrically connected to the fan through a wire, when the temperature of the inner cavity of the shell is too high, the device block controls the fan to start, and the fan and the electromagnet are electrically connected in series. When the fan starts, the electromagnet is energized, and then under the effect of opposites attracting each other, the push plate moves backward, driving the shield plate to move backward, so that the area of ​​air flowing through the vent is increased, thereby accelerating the heat dissipation. After the temperature of the inner cavity at the rear side of the main body is reduced, the fan is powered off, and the electromagnet is also powered off. The push plate automatically moves forward under the elastic force of the spring, so that the shield plate blocks part of the vent, thereby preventing external impurities from entering the inner cavity at the rear side of the main body through the vent, thereby achieving the effect of quick disassembly or installation.

Therefore, when in use, when the temperature of the inner cavity of the shell 4 is too high, the equipment block 2 controls the fan 3 to start, and the fan 3 is electrically connected in series with the electromagnet 8. When the fan 3 is started, the electromagnet 8 is energized, and then under the effect of opposites attracting each other, the push plate 10 moves backward, driving the baffle 11 to move backward, so that the area of ​​air flowing through the vent 6 is increased, thereby accelerating the heat dissipation. A plug rod 12 is fixedly installed on the front side of the bottom of the inner cavity of the shell 4, and limiting holes 13 are provided on the front sides of the left and right sides of the shell 4. Baffles 14 are movably installed on the front sides of the left and right sides of the shell 4 through a rotating shaft. The position of the baffle 14 is located on one side of the limiting hole 13, and the shape of the baffle 14 is larger than the inner surface of the limiting hole 13.
