[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0024] Reference Figures 1 to 7, this application provides a heating device with a waterproof cap, including: a heating device main body 1, a porcelain bead 2, and a waterproof cap 3. A first through hole 4 for inserting the porcelain bead 2 is provided at the lower part of the heating device main body 1. An electric heating wire extends at the lower part of the heating device. A power plug 5 is inserted into the porcelain bead 2, and the power plug 5 is connected to the electric heating wire. The waterproof cap 3 is detachably connected to the bottom of the porcelain bead 2, and a second through hole 6 for the power plug 5 to pass through is provided on the waterproof cap 3.
[0025] In some embodiments, first clamping grooves 7 are respectively provided on both outer sides of the porcelain bead 2. First clamping blocks 8 are respectively provided on both inner sides of the second through hole 6 corresponding to the first clamping grooves 7. The first clamping blocks 8 are elastically arranged in the second through hole 6. The waterproof cap 3 can be fixed at the bottom of the porcelain bead 2 through the clamping connection between the first clamping blocks 8 and the first clamping grooves 7.
[0026] In some embodiments, the material of the waterproof cap 3 is high-temperature resistant silica gel; the first clamping blocks 8 are integrally formed on the inner side of the second through hole 6. The waterproof cap 3 made of high-temperature resistant silica gel can be elastic while being high-temperature resistant, making it easier to be loaded and unloaded on the porcelain bead 2.
[0027] In some embodiments, a second clamping block 9 is provided at the bottom end of the first clamping groove 7, and a second clamping groove 10 for the second clamping block 9 to engage with is provided below the first clamping block 8 to ensure that the installed waterproof cap 3 is not easily loosened.
[0028] In some embodiments, an isolation area 11 is provided between the second through hole 6 and the power plug 5 to prevent the high-temperature and charged power plug 5 from contacting the waterproof cap 3.
[0029] In some embodiments, the bottom edge of the waterproof cap 3 extends downward to form a cap 12. The cap 12 facilitates the connection of the waterproof cap 3 with the components in the cooking appliance and better prevents water ingress.
[0030] In some embodiments, the power plug 5 is welded to the electric heating wire.
[0031] In some embodiments, a jack 13 for inserting the power plug 5 is provided through the porcelain bead 2 from the top surface to the bottom surface. A slot 14 is provided at the top of the jack 13; the top end of the power plug 5 is bent, and the top end of the power plug 5 is received in the slot 14.
