Description

Technical Field

[0001] The utility model relates to the technical field of electric heating control devices, in particular to a preheating controller. Background Art

[0002] The preheating controller is an important device used to control the temperature of heating equipment. It is widely used in industrial production and automobile engine preheating systems. In automobile engine preheating systems, the preheating controller controls the heating of the preheating plug according to the temperature of the engine coolant, thereby increasing the temperature of the combustion chamber, shortening the engine starting time, and reducing the wear on the engine caused by cold start.

[0003] The preheating controller is usually connected to the preheater through a cable or line, and is used to control the opening and closing of the preheater and the preheating temperature and other parameters. When the preheating controller is installed inside the diesel engine, it is susceptible to the invasion of water vapor and dust. Common preheating controllers are not equipped with corresponding waterproof and dustproof measures. Moisture entering the controller may easily cause a short circuit or damage. Dust adhering to the surface of the sensor in the preheating controller may interfere with the normal operation of the sensor and cause inaccurate temperature measurement. Therefore, a preheating controller is needed to solve the above problems. Utility Model Content

[0004] The purpose of the present utility model is to provide a preheating controller to solve the problem raised in the above background technology: the preheating controller is easily invaded by water vapor and dust when installed inside the diesel engine, and the common preheating controller is not provided with corresponding waterproof and dustproof measures. Moisture enters the inside of the controller, which can easily cause a short circuit or damage. Dust adheres to the surface of the sensor in the preheating controller, which will interfere with the normal operation of the sensor and cause inaccurate temperature measurement.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a preheating controller, including a protective shell, a waterproof dust removal component is installed between the two sides of the inner wall of the protective shell, the interior of the protective shell is slidably connected to the preheating controller body, the two sides of the preheating controller body are in contact with the center of the waterproof dust removal component, the preheating controller body and the protective shell are connected by an installation component, and a positioning connecting plate is provided at the end of the protective shell away from the preheating controller body, and a positioning screw hole is provided at the center of the positioning connecting plate.

[0006] Preferably, the waterproof and dust removal assembly includes four partition baffles, and a material storage shell is fixedly connected between each of the partition baffles and the inner wall of the protective shell, and the interior of each of the material storage shells is filled with activated carbon blocks.

[0007] Preferably, each of the material storage shells is provided with a connecting guide plate on one side close to the preheating controller body, each of the connecting guide plates is provided with multiple ventilation holes, and connecting slides are provided at the center of both sides of the preheating controller body, and the two connecting slides pass through two partition baffles that are positioned opposite each other.

[0008] Preferably, the mounting assembly includes two U-shaped connecting plates, which are fixedly connected to the top and bottom of the preheating controller body respectively, and the protective shell is provided with two positioning blocks near the preheating controller body.

[0009] Preferably, the two positioning blocks are connected through-and-through with the U-shaped connecting plates facing each other, first connecting through holes are provided on both sides of the two U-shaped connecting plates, second connecting through holes are provided on both sides of the two positioning blocks, and positioning screws are connected through-and-through with the U-shaped connecting plates facing each other.

[0010] Preferably, the positioning screw passes through the first connecting through hole and the second connecting through hole in sequence, and both ends of the positioning screw are threadedly connected with positioning nuts, and the two positioning nuts are in contact with the U-shaped connecting plates at opposite positions.

[0011] The technical effects and advantages of this utility model are:

[0012] (1) This device absorbs water vapor and dust through the activated carbon block placed in the material housing to prevent water vapor and dust from affecting the use of the preheating controller body. The preheating controller body and the protective housing can be installed and connected by the installation component. When the preheating controller body needs to be taken out for maintenance, the positioning nut is removed, the positioning screw is pulled out, and the preheating controller body can be slid out so that the connecting slide slides out from between the partition baffles. The preheating controller body can be repaired. After the maintenance is completed, the preheating controller body is reset, the positioning screw is reset, and the positioning nut is tightened. The U-shaped connecting plate and the positioning block are limited by the positioning nut and the positioning screw, thereby completing the connection between the protective housing and the preheating controller body. This solves the problem that the preheating controller is easily invaded by water vapor and dust when installed inside the diesel engine. Common preheating controllers are not equipped with corresponding waterproof and dustproof measures. Moisture enters the controller, which can easily cause a short circuit or damage. Dust adheres to the surface of the sensor in the preheating controller, which will interfere with the normal operation of the sensor and cause inaccurate temperature measurement.

[0013] (2) This device can protect the outer shell of the preheating controller body by providing a protective shell. Since the protective shell is made of polyimide material, its electrical properties and insulation properties are stable. It can still maintain excellent insulation under high temperature, high pressure, high speed, high humidity and other environments, and can protect the preheating controller body. The positioning connecting plate can be used to position the protective shell and position the protective shell inside the diesel engine. BRIEF DESCRIPTION OF THE DRAWINGS
