Detailed description of the invention
Be clearly and completely described the technical scheme in the application below in conjunction with accompanying drawing, obviously, described embodiment is only a part of embodiment of the application, instead of whole embodiments.Based on the embodiment in the application, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of the application's protection.
As shown in Figure 1-2, electric-heating cooking appliance described in the application comprises: pot body 1, to be arranged on pot body and pot lid of being articulated and connected of one end and pot body, this pot lid comprises cover 21, be arranged at the lining lid 22 in cover and removable inner cap 23, the front end of lining lid 22 is provided with the connection sliding block 24 and slide block 25 of uncapping that can radially slide, and connection sliding block 24 and uncap between slide block 25 and be provided with elastic component 26, the inner side of connection sliding block 24 is provided with the draw-in groove 241 for installing removable inner cap 23, removable inner cap 23 is provided with the grab 231 matched with draw-in groove 241, thus realize removably connecting of removable inner cap 23 and connection sliding block 24.
As shown in Figure 1, when not installing removable inner cap 23, slide block 25 of uncapping shrinks in cover 21, if now user fastens pot lid, slide block 25 of uncapping can not engage with pot body, that is slide block 25 of uncapping cannot snap in the middle annular groove 11 on pot body 1 shown in Fig. 1, thus can not realize stew lid and the fastening of pot body, carry out the removable inner cap 23 of reminding user neglected loading with this.
As shown in Figure 2, when the grab 231 of removable inner cap 23 is installed in draw-in groove 241, connection sliding block 24 is extruded by removable inner cap 23, elastic component 26 is by compression, the slide block 25 that simultaneously promotes to uncap move forward the direction motion of annular groove 11 (in pot body), and pot lid is stretched out in the front end of the slide block 25 that makes to uncap, and now fastens pot and covers, the uncap front end of slide block 25 is fastened and connected with the middle annular groove 11 of pot body, reaches pot lid and the object that engages of body 1 of stewing.
As shown in Figure 3, the front side of cover 21 is provided with button 3 of uncapping, when press uncap button 3 time, the front bottom end of button 3 of uncapping offsets with slide block 25 of uncapping, button 3 of uncapping promotes to uncap slide block 25 toward interior motion (the direction motion towards away from annular groove 11 in pot body), meanwhile elastic component 26 is squeezed, uncap slide block 25 indentation backward thus with pot body 1 be separated, make pot lid open.After unclamping button 3 of uncapping, slide block 25 of uncapping is ejected again cover 21 under the elastic reaction of elastic component, and slide block 25 of uncapping when closing lid next time can engage with pot body 1 again.
In this programme, elastic component 26 is spring, as shown in Figure 1, the side that connection sliding block 24 is connected with slide block 25 of uncapping is provided with the first joint pin 242, the side that slide block 25 of uncapping is relative with connection sliding block is provided with the second joint pin 251, one end of spring is sheathed on the first joint pin 242, its other end is sheathed on the second joint pin 251, spacing is provided with between first joint pin 242 and the second joint pin 251, and the spacing between the first joint pin and the second joint pin is greater than the stroke sum of connection sliding block 24 and slide block 25 slide in opposition of uncapping, to guarantee when being provided with removable inner cap, press button pot lid of uncapping can open smoothly.The removable inner cap installation and removal of the new electrically heating cooking apparatus of the application are convenient, if the removable inner cap of user's neglected loading, can not closing lid, and guarantee use safety.
In this programme, can also be directly fixedly connected with connection sliding block 24 one end of spring, its other end is fixedly connected with slide block 25 of uncapping, and can reach the goal of the invention of this programme equally.
Wherein, connection sliding block 24 and slide block 25 of uncapping adopt composite to be prepared from, and it comprises each composition of following parts by weight:
