It has advantages such as high control accuracy and good stability, and is widely used in many fields such as industrial production, scientific research experiments, medical equipment, and smart homes, such as temperature control of plastic extruders, temperature maintenance of laboratory incubators, and temperature regulation of household air conditioners.

[0003] Existing temperature controllers do not have the function of preventing accidental touch. In actual use, the operation buttons of temperature controllers are usually exposed without any protective measures. This makes it easy for workers to accidentally touch the operation buttons of the temperature controller when operating other equipment or walking around during daily work, especially in the workplace where there is frequent personnel movement. This can easily cause the temperature controller to control the temperature incorrectly.

[0004] Therefore, this utility model provides a PID temperature controller to prevent accidental activation, thereby solving the above-mentioned problems. Utility Model Content

[0015] (III) Beneficial Effects

[0016] 1.

This design is simple to operate and inexpensive, thus avoiding accidental touch and pressing.

[0017] 2. The anti-accidental touch mechanism effectively prevents the support from rotating, thus preventing the disc teeth from rotating unexpectedly without any intention to operate.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] This utility model provides a temperature controller, such as Figures 1 to 5 As shown, the device includes a thermostat body 1. An operation panel 101 is provided on the front of the thermostat body 1. A button 102 is movably installed on the side of the thermostat body 1 near the operation panel 101. An anti-touch component 2 is movably sleeved on the outer arc surface of the button 102. A plate 201 is provided at the bottom of the lower surface of the anti-touch component 2. A pressure tooth 202 is provided on the lower surface of the plate 201. An elastic part 203 is provided on the upper surface of the anti-touch component 2. A slot 204 is provided at the connection between the elastic part 203 at the top of the anti-touch component 2 and the plate 201. The inner arc surface of the slot 204 is movably sleeved with the button 102. The anti-touch component 2 is placed on one side of the thermostat body 1. An anti-accidental touch mechanism 3 is movably engaged on the outer arc surface of the pressure tooth 202.

[0027] An anti-touch component 2 is tightly fitted around the button 102. One side of the plate 201 is tightly fitted to the surface of the thermostat body 1, and one side of the anti-touch component 2 is provided with an elastic part 203. The elastic part 203 arches outward, which can effectively protect the button 102 inside the arched bottom slot 204, thereby avoiding accidental touch.

[0028] When operation is required, the operator only needs to press the elastic part 203 inward, and the elastic part 203 will drive the anti-touch component 2 to move synchronously, thereby pressing the button 102 and smoothly achieving the control purpose. This design is simple to operate and inexpensive. The elastic part 203 is made of elastic plastic in the form of an elastic ring. During the inward pressing process, the elastic part 203 is easily stretched, which can reliably ensure the control operation of the button 102.

[0029] The anti-accidental touch mechanism 3 includes a disc tooth 301 that meshes with the pressure tooth 202. A support 302 is provided on the lower surface of the disc tooth 301. A stop plate 303 is movably sleeved on the outer arc surface of the support 302. A hinge portion 304 is provided on the outer arc surface of the stop plate 303. One end of the hinge portion 304 penetrates and connects to the interior of the thermostat body 1. A through hole is provided on one side of the stop plate 303. A stop arm 305 is provided on the inner arc surface of the stop plate 303. The stop arm 305 is an elastic mechanism. There are four stop arms 305, arranged in a circular array on the inner arc surface of the stop plate 303. The inner arc surfaces of the multiple stop arms 305 are movably engaged with the outer arc surface of the support 302. The outer arc surface of the button 102 penetrates to the disc tooth 301. Inside, a protective frame 306 is fitted on the bottom of the outer arc surface of the button 102. An arc-shaped support arm 307 is provided on the outer arc surface of the protective frame 306. The arc-shaped support arm 307 is vertically downward along the protective frame 306. A docking groove 308 is provided on one side of the outer arc surface of the arc-shaped support arm 307. There are four arc-shaped support arms 307, which are distributed in a circular array outside the protective frame 306. The four arc-shaped support arms 307 are correspondingly adapted to the four stop arms 305. A kit 309 is slidably engaged on the inner arc surface of the docking groove 308. A connecting strip 310 is provided on the inner arc surface of the kit 309. One side of the connecting strip 310 is movably engaged into the docking groove 308. One side of the kit 309 is connected through to the surface of the thermostat body 1.

[0030] Meanwhile, the buttons in the thermostat body 1 have diverse input methods. Not only can they be input through conventional pressing, but they also have a unique rotation input function. Pressure teeth 202 are provided on the bottom surface of the plate 201. One side of these pressure teeth 202 is tightly engaged with another disc tooth 301. Through this ingenious engagement design, the rotation range of the stop disc tooth 301 can provide all-round protection for the button 102 that is completely covered by the plate 201, effectively preventing accidental contact from the outside.

[0031] The rear end of the disc tooth 301 is connected to the support 302. A stop plate 303 is fitted onto the outer arc surface of the support 302. It is worth noting that the hinge portion 304 around the stop plate 303 is fixed to the surface of the thermostat body 1. This means that in the initial state, the stop plate 303 is completely fixed. Inside the stop plate 303, a stop arm 305 is provided. This stop arm 305 has a certain elasticity and can be tightly engaged with the outer arc surface of the support 302. The stop arm 305 is engaged with the outer arc surface of the support 302 through its elasticity. Since the rear end of the support 302 is connected to the pressure tooth 202 on the bottom surface of the plate 201... When the anti-rotating arm 305 is in operation, the meshing disc teeth 301 can effectively prevent the support 302 from rotating, thereby preventing the disc teeth 301 from rotating accidentally without any intention to operate. This fundamentally avoids the mis-rotation of the disc teeth 301, which would cause the position of the plate 201 to change and thus lead to the accidental touch of the button 102. If the operator accidentally touches the button while performing other operations near the thermostat, the presence of the anti-rotating arm 305 will prevent the button from rotating easily. Only when the operator clearly intends to perform the rotation operation and applies sufficient force will the disc teeth 301 rotate, thereby reducing the possibility of misoperation.

[0032] To further enhance the stability of the entire structure, a protective frame 306 is fitted onto the outer arc surface of the button 102. This protective frame 306 is composed of multiple arc-shaped support arms 307. During installation, these arc-shaped support arms 307 initially tend to expand outward between the components 309. As they approach the opening of the component 309, the arc-shaped support arms 307 contract inward due to the restriction of the opening structure, and then smoothly penetrate to the outside of the component 309. Once they pass through the component 309, the arc-shaped support arms 307 will quickly and fully unfold. Due to the structural change, they can be accurately and firmly locked inside the component 309.

[0033] It is worth mentioning that the kit 309 is securely installed inside the thermostat body 1, remaining relatively stationary. Furthermore, connecting strips 310 are provided on the inner arc surface of the kit 309. These connecting strips 310 are adapted to the pre-drilled mating grooves 308 on the arc-shaped support arm 307, allowing for a firm connection. This connection method not only further enhances the connection stability between the protective frame 306 and the kit 309, but also makes the entire structure an organic whole within the thermostat body 1, effectively resisting various impacts and interferences that may arise from the outside, comprehensively ensuring the safety of the button 102, and improving the overall stability and reliability of the thermostat.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
