Abstract
The improvement structure of electric heating pot sealing, comprise a pot body, be arranged on the interior pot with sealing surface in pot body, be arranged on the pot cover with O-ring seal on pot body, O-ring seal is embedded in the annular embedding groove of pot cover, it is characterized in that the lower end of sealing ring is provided with the ring of plural protrusion, when pot cover covers, the ring of plural protrusion abuts against on the sealing surface of interior pot. Compared with the prior art the present invention, has good airproof performance, can effectively prevent the advantage that food overflows.
Description
Technical field:
The present invention relates to a kind of family power technology.
Background technology
As shown in Figure 1, everybody known anti-overflow sealing at present generally adopts the method for flat seal to seal food, because the contact area of flat seal is large, the flatness of plane is inhomogeneous, causing can not effective sealing, thereby occurs that food overflows, and liquid causes the security risks such as electric leakage to product.
Summary of the invention:
Goal of the invention of the present invention is to provide a kind of good airproof performance, can effectively prevent the improvement structure of the electric heating pot sealing that food overflows.
The present invention realizes like this, comprise a pot body, be arranged on the interior pot with sealing surface in pot body, be arranged on the pot cover with O-ring seal on pot body, O-ring seal is embedded in the annular embedding groove of pot cover, its special feature is that the lower end of sealing ring is provided with the ring of plural protrusion, when pot cover covers, the ring of plural protrusion abuts against on the sealing surface of interior pot.
Owing to adopting the contact of ring of plural protrusion instead of the contact of the lower surface of whole sealing ring, like this, the ring of protrusion will be subject to the effect of enough pressure and be out of shape, and has ensured the effect of sealing.
Here, the cross section of the lower end of the ring of protrusion is curved. Adopt arc, ensured that the ring protruding has enough distortion by the sealing surface sealing of interior pot.
In O-ring seal, the cell wall place, inner side of the annular embedding groove of corresponding pot cover is provided with groove, is the recess of adjacent two interannulars that protrude below groove. Like this, the pressure that the inner side cell wall of the annular embedding groove of pot cover applies in O-ring seal just evenly spreads on the ring of adjacent protrusion on recess both sides, has ensured that adjacent two rings that protrude are subject to enough pressure by the sealing surface sealing of interior pot.
Here, the arranged outside of the sealing surface of interior pot has side seal face, and side seal is the outside cell wall for the annular embedding groove of pot cover towards convex, and the outside of the O-ring seal of respective side sealing surface is inner concavity, when pot cover covers, the outside of the O-ring seal of inner concavity abuts against on side seal face. While being applied to O-ring seal due to the inner side cell wall of the annular embedding groove of pot cover, make the ring of the outer protrusion of recess have the trend of outside movement, thereby make the outside of O-ring seal of inner concavity stressed and on the side seal face of abutting against.
Compared with the prior art the present invention, has good airproof performance, can effectively prevent the advantage that food overflows.
Brief description of the drawings:
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present invention;
Fig. 3 is the partial enlarged drawing that the A of Fig. 2 is ordered.
Detailed description of the invention:
Now in conjunction with the accompanying drawings and embodiments the present invention is described in further detail:
As Fig. 2, shown in 3, the present invention includes the pot body 2 of inner bottom part with electric heating mechanism 1, be arranged on the interior pot 4 with sealing surface 3 in pot body 2, be hinged on the pot cover 6 with O-ring seal 5 on pot body 2, O-ring seal 5 is embedded in the annular embedding groove 7 of pot cover 6, its special feature is that the lower end of sealing ring 5 is provided with the ring 8 of plural protrusion, when pot cover 6 covers, the ring 8 of plural protrusion abuts against the (profile of the ring 8 of the protrusion while distortion in order to show on the sealing surface 3 of interior pot 4, the lower end of the ring 8 Hai districts distortion of the protrusion in accompanying drawing is positioned at below sealing surface 3, actual conditions be the lower end that is positioned at the ring 8 of the protrusion below sealing surface 3 be out of shape and abut against sealing surface 3 above).
The cross section of the lower end of the ring 8 protruding is curved.
In O-ring seal 5, the cell wall 7a place, inner side of the annular embedding groove 7 of corresponding pot cover 6 is provided with groove 9, and groove 9 is the recess 10 of 8, adjacent two ring protruding below.
The arranged outside of the sealing surface 3 of interior pot 4 has side seal face 11, side seal face 11 inwardly protrudes from the outside cell wall 7b of the annular embedding groove 7 of pot cover 6, the outside 5a of the O-ring seal 5 of respective side sealing surface 11 is inner concavity, when pot cover 6 covers, the outside 5a of the O-ring seal of inner concavity abuts against on side seal face 11.
