The device can be installed and slid by the cooperation of the support plates 15 and the mounting holes 16.
[0025] The working principle of this utility model is as follows: First, the different raw materials of the scented candle are stored separately inside multiple heating cylinders 2. The heating cylinders 2 can heat the raw materials to maintain a suitable liquid flow state. Then, the injector 3 is used for quantitative injection, which can quantitatively add different types of raw materials. This allows the liquid raw materials inside the heating cylinders 2 to be quantitatively added into the mixing cylinder 1. Next, the mixer 4 is started to work, which can heat and stir the mixed raw materials to ensure uniform temperature and good fluidity of the raw materials during the mixing process. Then, the mixed raw materials are drawn by the discharge pump 7 and delivered to the discharge solenoid valve 8. The discharge solenoid valve 8 can precisely control the opening time and flow rate according to the set program to achieve quantitative discharge.
