DETAILED DESCRIPTION
[0023] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] The embodiment of the present application provides an electric lunch box with a detachable heating base, which solves the problem that the heating base of the current electric lunch box is also a sealing base at the bottom, which plays a role of bottom sealing protection during carrying. This means that the heating base needs to be carried with the lunch box when in use, and various electrical components are arranged inside the heating base. The risk of collision and falling during carrying increases.
[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0026] The utility model embodiment discloses an electric lunch box with a detachable heating base.
[0027] According to the attached Figure 1-5 As shown, it includes an electric heating seat 1 and a heat-conducting container 2 integrally arranged on the top of the electric heating seat 1. A display screen 3, an adjustment switch 4 and a power-carrying wire 5 are installed on the outer surface of the electric heating seat 1.
[0028] A lunch box body 7 is arranged on the top of the electric heating seat 1, and a sealing cover 8 is installed on the top of the lunch box body 7. The lunch box body 7 includes:
[0029] The outer shell 71 and the steam flow hole 76 are provided at the bottom of the outer shell 71;
[0030] A food grade stainless steel container 74, which is disposed inside the outer shell 71;
[0031] The sealing rubber plug 73 is movably plugged into the inner top of the steam flow hole 76 .
[0032] A sealing connection part 72 is provided at the bottom of the outer shell 71, and connecting grooves for assembling the sealing connection part 72 are provided on the inner top of the outer shell 71 and the heat-conducting container 2. A steam circulation hole 76 passes through the sealing connection part 72, which is used for stacking multiple lunch box main bodies 7, and at the same time, the lunch box main body 7 is connected to the electric heating seat 1.
[0033] A connecting plate 77 is fixedly installed on the top of the sealing rubber plug 73, and the connecting plate 77 is against the bottom of the food-grade stainless steel container 74. When carried, the food-grade stainless steel container 74 squeezes the connecting plate 77, so that the sealing rubber plug 73 remains inside the steam circulation hole 76 to achieve sealing.
[0034] Both sides of the food-grade stainless steel container 74 are provided with connecting holes 75 for steam to flow upward when the multiple layers of lunch box bodies 7 are stacked and heated simultaneously.
[0035] A handle 11 is rotatably provided on the top of the sealing cover 8, an exhaust seat 9 is installed in the middle of the sealing cover 8, and an exhaust baffle 12 is rotatably provided inside the exhaust seat 9. Both the exhaust baffle 12 and the exhaust seat 9 are provided with air outlet holes. During heating, the exhaust baffle 12 is rotated to make the two groups of air outlet holes staggered to avoid steam leakage. After heating is completed, the exhaust baffle 12 is rotated to make the two groups of air outlet holes overlap to exhaust and reduce pressure.
[0036] Blocks 6 are fixedly installed on both sides of the top of the electric heating seat 1 and the outer shell 71 , and lock buckles 10 are rotatably connected to both sides of the bottom of the sealing cover 8 and the outer shell 71 , and the lock buckles 10 are movably connected to the outer surface of the block 6 .
[0037] In summary, compared with the prior art, the present invention has the following beneficial effects:
[0038] By modifying the lunch box body 7, a steam circulation hole 76 is opened at the bottom of the outer shell 71, and a sealing plug 73 is movably inserted into the inner top of the steam circulation hole 76, and a connecting plate 77 is fixedly installed on the top of the sealing plug 73. When in use, the electric heating seat 1 can be directly placed where it is needed, and is not carried with the lunch box body 7. The sealing plug 73 is used to seal the lunch box body 7 during carrying. When heating, the food-grade stainless steel container 74 is lifted, and then the connecting plate 77 is removed to move the sealing plug 73 out of the steam circulation hole 76. Then the lunch box body 7 is placed on the electric heating seat 1 for heating, so that the steam is discharged upward through the steam circulation hole 76 and the connecting hole 75 to heat the food inside the food-grade stainless steel container 74, thereby avoiding the problem of easy damage of the electric heating seat 1 when carried with the lunch box body 7, and the lunch box body 7 will not leak when carried alone.
