It is found in actual construction that the traditional ink fountain is prone to the following problems when used: 1. When used in a low temperature environment, the ink in the ink tank is prone to freezing and increased viscosity. The freezing of the ink will lead to the inability to print ink normally, which seriously affects the construction progress; and the increased viscosity of the ink will make the marking uneven and the line thickness inconsistent, affecting the construction accuracy; 2. In addition, after long-term use, the ink of the existing ink fountain is easy to dry up on the inner wall of the ink tank, which is difficult to clean; therefore, technical personnel in this field are in urgent need of an ink fountain for marking lines in construction that can solve the above problems.

The temperature sensor is arranged close to the heating chamber 8 for detecting the temperature near the heating chamber 8 in the outer shell 1. A display 5 is also provided on the outer shell 1 for displaying the temperature value detected by the temperature sensor. The heating wire 9 and the display 5 are both connected to the main controller; a battery cover 7 for facilitating battery replacement is provided on the outer shell 1. A first row of ink holes is arranged at the bottom of the ink tank 10, a second row of ink holes is arranged at the bottom of the heating tank 8 corresponding to the first row of ink holes, and a third row of ink holes is arranged at the bottom of the outer shell 1 corresponding to the first row of ink holes. An ink discharge pipe connecting the first row of ink holes, the second row of ink holes and the third row of ink holes is also included, and a plug is arranged at the lower end of the ink discharge pipe. After each construction is completed, the plug needs to be removed to allow the residual ink in the ink tank 10 to be discharged through the ink discharge pipe to prevent the ink from drying up and solidifying in the ink cartridge.

[0020] The main controller is provided with a wireless communication module, which can be connected to the APP on the terminal through the wireless communication module to set the low temperature limit value; when the temperature value detected by the temperature sensor is lower than the preset low temperature limit value, the main controller can control the heating wire 9 to heat the ink tank 10, and then heat the ink and ink-absorbing sponge 11 inside the ink tank 10 to prevent the ink and the ink-absorbing sponge 11 from being frozen in a low temperature environment; it effectively solves the problem of ink freezing and increased viscosity in a low temperature environment, and ensures the smooth progress of the line drawing operation.
