The utility model is characterized in that a touch switch for controlling the opening and the closing of the electric heating circuit power is arranged between the pan cover locking device and the pan body; and the input terminal of the touch switch is externally connected with a power circuit. The electric pressure cooking saucepan cover with retractable safety device has simple structure, reasonable layout, reliable safety performance, convenient operation, environmental protection, energy saving and excellent popularization value.
Description
Technical field
The utility model relates to the pressure cooker technical field, particularly a kind of electric pressure cooking saucepan lid with the folding safety device.
Background technology
At present, the cover closing/opening safety guard is all arranged, because according to national Specification on the existing pressure cooker, no matter be the pressure cooker that heats by gas furnace, still the electric pressure cooking saucepan by the electric calorifie installation heating fastens when not in place at pot cover, and pot inner pressure should not surpass 4kpa; When pot inner pressure surpassed 4kpa, pressure cooker can not be opened.The pressure cooker that existing market is generally the used condensating cover safety device of uncapping when not having pressure in the pot, puts in place by promoting push button, thereby opens pressure cooker cover; Certainly, also have without push button and the cover closing/opening safety device is arranged.But, because the existing condensating cover safety device of uncapping ensures that just pressure cooker can be according to national Specification work, for electric pressure cooking saucepan, when pot cover fastens when not in place, though pot inner pressure is no more than 5kpa, electro-heat equipment is in running order always, the waste power supply, and after the pot cover of pressure cooker was opened, pressure cooker itself can also continue heating, has certain potential safety hazard.
Summary of the invention
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of not only simple and reasonable, security performance is reliable, easy to operate, and the electric pressure cooking saucepan of the band folding safety device of environmental protection and energy saving lid.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of electric pressure cooking saucepan lid with the folding safety device, comprise pot cover, the edge of pot cover is provided with the pot cover locking device that fastens with the pot body, be provided with electric heating assembly and control circuit thereof in the pot body, it is characterized in that: be provided with the touch switch of control electric heating circuit on/off between described pot cover locking device and the pot body, the input external power supply circuit of this touch switch.
As further specifying of such scheme, described touch switch is a pressing type control switch, comprise insulating base and interior conductive plate thereof, be provided with that part remains in the insulating base and part is exposed to the outer contact assembly that is equipped with elasticity reset device, this contact assembly has a contact site and a pressure section, contact site electrically contacts with conductive plate, and pressure section is connected with the edge movable of pot cover locking device.
Described conductive plate electrically connects with the control circuit of the interior electric heating assembly that is provided with of pot body, has indicator lamp in parallel with electric heating assembly on its connection line.
Described touch switch is the induction type electronic switch, this switch comprises position sensor and electronic circuit, circuit pack is made up of controller, relay switch, constant current output circuit and power supply, position sensor is connected in the signal input part of controller, controller connects the control relay switch, and this relay switch links to each other by the electric heating assembly control circuit that is provided with in constant current output circuit and the pot body.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts between pot cover locking device and pot body setting can control the touch switch of electric heating circuit on/off, makes the pot cover can only be after locking puts in place, and power supply could be connected; After pot cover breaks away from this position, or before not closing lid fully and putting in place, heater circuit all can not be worked, and has guaranteed the safe in utilization of this product, has reduced the consumption of the energy, reduces user cost, and is safe and practical again.

The specific embodiment
Embodiment 1
As Fig. 1～shown in Figure 4, the electric pressure cooking saucepan lid of the utility model band folding safety device, comprise pot cover 1, the edge of pot cover 1 is provided with the pot cover locking device that fastens with pot body 2, be provided with electric heating assembly 3 and control circuit thereof in the pot body 2, be provided with the touch switch 4 of control electric heating circuit on/off between pot cover locking device and the pot body 2, the input external power supply circuit of this touch switch 4, in the present embodiment, touch switch 4 is a pressing type control switch, comprise insulating base 4-1 and interior conductive plate 4-2 thereof, be provided with that part remains in the insulating base and part is exposed to the outer contact assembly 4-4 that is equipped with elasticity reset device 4-3, this contact assembly 4-4 has a contact site and a pressure section, contact site electrically contacts with conductive plate 4-2, conductive plate electrically connects with the control circuit of the interior electric heating assembly 3 that is provided with of pot body, the pressure stroke K switch is arranged on its connection line, temperature limiter C and timer T connect with electric heating assembly 3, electric heating assembly 3 is parallel with indicator lamp, and the pressure section of this contact assembly 4-4 is connected with the edge movable of pot cover locking device.
In the use, earlier the pot cover fastening is put in place, make the pot cover edge press down the pressure section of contact assembly, the other end contact site of contact assembly contacts with conductive plate, makes the pot nside circuit connect power supply; When opening pot cover, contact assembly resets under the effect of elasticity reset device, and its contact site is separated with conductive plate, and the pot nside power supply disconnects.
The difference of present embodiment and above-mentioned embodiment is, described touch switch can also adopt the induction type electronic switch, this switch comprises position sensor and electronic circuit, circuit pack is made up of controller, relay switch, constant current output circuit and power supply, position sensor is connected in the signal input part of controller, controller connects the control relay switch, and this relay switch links to each other by the electric heating assembly control circuit that is provided with in constant current output circuit and the pot body.
