The rubber plug includes a plug body and a buckling position, and the plug body is arranged on the upper surface of the plug body, and the plug The inner bowl is set inside the outer bowl. The outer wall of the inner bowl and the inner wall of the outer bowl form a cavity that can hold water. The bowl cover includes a cover body. The lower surface of the cover body is provided with a ring convex ring. The outer wall of the ring convex ring is provided with a washer. When the cover body is on the inner bowl, the washer is closely connected with the inner wall of the inner bowl. The top surface of the cover body is provided with an air valve installation groove, and the air valve is installed in the air valve installation groove. The utility model has the advantages of convenient irrigation or pouring water, glue plug is inserted into the inlet and outlet after irrigation, and water overflow is prevented. By setting an air valve, the pressure difference between the inside and outside of the bowl cover can be balanced according to need, and the opening of the bowl cover is convenient and labor-saving.
【技术实现步骤摘要】
保温碗
本技术涉及婴幼儿用品
,特别是保温碗。
技术介绍
夏冬两季里,婴幼儿在吃饭进食时,由于传统的碗不具有保温功能,因而导致食物易变质,对婴幼儿身体带来影响。保温碗是婴幼儿餐具的一种,由于婴幼儿需要喂食,导致吃饭所需时间长,饭菜如果不进行保温很容易变凉,影响婴幼儿食用和消化。通过保温碗便可以对饭菜提供一定的保温作用,减缓饭菜变凉的时间。现有的保温碗有两种,一种为真空保温类型的保温碗,其特点在于保温碗的内壁和外壁之间具有真空层,利用真空层阻隔热量向外界传递,从而可以单次延长碗内食物降温的时间,但不能连续保温。另一种为注热水保温类型的餐具,但现有的注热水保温碗在注入适宜温度的水后,水容易从注入口处溢出,为了降低水溢出的可能性,注入口往往较小,但会导致灌水或倒水不方便。通常情况下,保温碗会配备碗盖,以减缓碗内温度变化速度,而且碗盖与碗体为密封紧配合,在温度发生变化后,碗盖内外侧产生压差,导致碗盖开启困难。
技术实现思路
本技术的目的在于克服现有技术的缺点,提供一种保温碗,通过进出水口注入或倒出水,使得灌水或倒水方便,灌水后胶塞塞入进出水口,防止水溢出,通过设置气阀,可根据需要,平衡碗盖内外侧压差,开盖方便、省力。本技术的目的通过以下技术方案来实现:保温碗,包括外碗、内碗、胶塞、碗盖和气阀,所述外碗包括外碗体和进出水口,所述进出水口设于外碗体的侧壁上部,且所述进出水口与外碗体的内侧连通,所述进出水口的上边缘处设有扣沿,所述胶塞包括塞体和扣位,所述扣位设于塞体的上表面上,所述塞体塞入进出水口内,且扣位压接在扣沿的上表面上,所述内碗套装于外碗体内侧,所述内碗的外壁与外 ...
