Description

Technical Field

[0001] This utility model relates to the field of hot water tank technology, and in particular to an automatic thermostat device for hot water tanks. Background Technology

[0002] Hot water tanks are widely used in numerous industrial production processes and everyday life applications. However, maintaining a constant water temperature inside the tank is a critical issue.

[0003] Traditional hot water tank temperature control methods often require frequent manual monitoring of water temperature and manual adjustment of the heating source. This method is not only labor-intensive, but also difficult to maintain the water temperature within the set range due to the untimely and inaccurate nature of manual operation, which can easily lead to large temperature fluctuations. Therefore, we propose an automatic temperature control device for hot water tanks to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automatic thermostat for hot water tanks.

[0007] A steam pipe is provided on one side of the hot water tank. A regulating pipe is installed on the steam pipe. A regulating mechanism for regulating steam flow is provided inside the regulating pipe. The regulating mechanism includes a rotating shaft and an regulating plate. Rotating shafts are rotatably installed on the top and bottom inner walls of the regulating pipe. The same regulating plate is fixedly installed at the end of the two rotating shafts that are close to each other. The regulating plate is adapted to the regulating pipe.

[0009] Preferably, a housing is installed on the top of the regulating tube, a drive mechanism is provided on the housing, and a transmission mechanism is provided between the drive mechanism and the rotating shaft.

[0010] Preferably, the driving mechanism includes a driving plate and a cylinder. The cylinder is fixedly installed on one side of the housing, the driving plate is slidably installed inside the housing, and the output shaft of the cylinder is fixedly connected to the driving plate.

[0011] Preferably, the transmission mechanism includes a rack seat and a rotating gear. The top end of the rotating shaft extends into the housing and is fixedly mounted with the rotating gear. A rack seat is fixedly mounted on one side of the drive plate, and the rack seat meshes with the rotating gear.

[0012] Preferably, the controller is equipped with a display screen, and both the temperature sensor and the cylinder are electrically connected to the controller.

[0013] Preferably, a sealing ring is installed on the temperature sensor, and the sealing ring is adapted to the mounting sleeve. A mounting plate is also fixedly installed on the temperature sensor, and a disassembly and assembly mechanism is provided between the mounting plate and the mounting sleeve.

[0014] Preferably, the disassembly and assembly mechanism includes a mounting hole, a fixing screw, and a fixing nut. The mounting hole is formed on the mounting plate, and multiple fixing screws are fixedly installed on the mounting sleeve. The fixing screws pass through the mounting hole and are threaded with a fixing nut.

[0016] Preferably, limit grooves are provided on the inner walls of the front and rear sides of the housing, and limit seats are fixedly installed on the front and rear sides of the drive plate, with the limit seats slidably connected to the corresponding limit grooves.

[0017] The beneficial effects of this utility model are:

[0018] 1. The temperature sensor can detect the water temperature in the hot water tank. When the temperature is lower than the set temperature, the controller can start the cylinder. The cylinder can move the drive plate, which in turn moves the rack and pinion seat. The rack and pinion seat can rotate the rotating gear, which in turn rotates the adjusting plate via the rotating shaft. This allows the adjusting pipe to be opened and its opening size to be adjusted, thus automatically regulating the amount of steam entering the hot water tank for the purpose of automatic temperature control.
