Description

Liquid heater that sealing performance is good Technical Field The utility model relates to the technical field of liquid heaters, in particular to a liquid heater with good sealing performance. Background In the daily life of people, liquid heating machines such as humidifiers, electric rice cookers, health preserving kettles and the like are widely used. The traditional heating equipment has a certain commonality in structure that a cover body is provided with a sealing ring, and a main body is provided with an inner container. When using this kind of equipment, when closing lid and main part, the user needs to exert great effort downwards, just can the bottom of sealing washer wrap up the top edge of inner bag to realize the inside seal of equipment, user's use experience is felt relatively poor. However, during the heating of the liquid by the device, the liquid water gradually evaporates into steam, causing the pressure inside the device to rise continuously. When the steam pressure reaches a certain degree, upward pushing force can be generated on the sealing ring. Under the continuous influence of the acting force, a gap is gradually formed between the sealing ring and the liner. Once gaps appear, steam that would otherwise be confined to the interior of the device leaks along these gaps into the surrounding environment. The leakage of steam can not only reduce the pressure in the equipment, so that the preset heating temperature can not be reached, the heating effect is greatly influenced, the practicability of the equipment is reduced, but also the unnecessary waste of energy sources is caused, and the use cost is increased. Disclosure of utility model Aiming at the defects, the utility model provides the liquid heater with good sealing performance, the sealing part is tightly attached to the inner side wall of the liner, the gap between the liner and the mounting seat is effectively filled, steam and liquid are prevented from leaking from the gap, a reliable sealing environment is formed, and the problems of poor sealing effect and poor experience of the traditional liquid heater are solved. To achieve the purpose, the utility model adopts the following technical scheme: The utility model provides a liquid heater that sealing performance is good, includes lid and main part, the lid with the top of main part rotates to be connected, the lid includes mount pad and sealing washer, the main part is equipped with casing and inner bag, the mount pad is provided with steam exhaust hole, steam exhaust hole respectively with inner bag and external world are linked together, the sealing washer includes installation department, connecting portion and sealing part, the connecting portion is vertical to be connected the installation department with sealing part, the bottom of mount pad with installation department interference fit, the inner bag set up in the inside of casing, the outwards turn-up of sealing part forms into opening semicircular structure up, the lateral wall of sealing part with the inside wall looks butt of inner bag, sealing part be used for sealing the inner bag with clearance between the installation seat. The outer diameter of the tail end of the sealing part is larger than the inner diameter of the side wall of the inner container. The installation part, the connecting part and the sealing part are of an integrated structure, and the sealing ring is made of high-temperature resistant materials. The bottom of mount pad is provided with outwards bellied collar, the top of installation department is provided with inwards sunken mounting groove, the collar with the mounting groove sets up relatively and interference fit. The inside wall of installation department has seted up horizontal open-ended spliced groove, the lid still includes ventilative board, ventilative board's outside edge is located the spliced groove, ventilative board has seted up a plurality of vertical bleeder vents, and steam passes the bleeder vent gets into the mount pad. The inner side of the connecting part is provided with a horizontal steam baffle plate, the steam baffle plate comprises an arc edge and a straight line edge, the arc edge is mutually overlapped with the inner wall of the connecting part, and the straight line edge is connected with two end parts of the arc edge. The technical scheme of the utility model can have the following beneficial effects: 1. The mounting seat drives the head end of the sealing ring to move downwards, and at the moment, the inner wall of the liner is abutted against the tail end of the sealing part at any time. Elastic deformation occurs under the action of dual force, the sealing part is tightly attached to the inner side wall of the inner container, the gap between the inner container and the mounting seat is effectively filled, steam and liquid are prevented from leaking from the gap, and a reliable sealing environment is formed. 2. The integrally formed structure can ensure
