Abstract
The utility model relates to a vacuum fresh-keeping pressure cooker which comprises a pan body, a pan cover and a handle, wherein an opening-stop safety valve which is mounted on a valve seat is arranged on the pan cover. The vacuum fresh-keeping pressure cooker is characterized in that a seal ring which can be hermetically matched with a shoulder of the valve seat or a chuck structure which can control the dropping of the valve rod is mounted on the valve rod of the opening-stop safety valve. The vacuum fresh-keeping pressure cooker can keep food fresh besides possessing all functions of a normal pressure cooker, can further effectively improve the living quality of users, and obviously reduces the waste of food.
Description
Technical field
The utility model relates to the pressure cooker that a kind of family life is used, and relates in particular to food vacuum freshness retaining technology in summer, is intended to design a kind of home-use economical simple and easy fresh-keeping pressure cooker that is fit to.
Background technology
The food that contains moisture is put for a long time in air and can be gone bad, and especially during the broiling summer, food is more apt to deteriorate.The food spoilage reason is an action of microorganisms, and nutrient in growth of microorganism and the breeding pickuping food makes food lose original nutritive value, change and organize proterties and color, even also can produce unhygienic material, cause people's food poisoning, harm humans health.The foodstuff waste phenomenon that food spoilage causes is very serious, especially in the rural area.And bacterium is difficult for existence under the vacuum environment, goes bad so vacuum packaging can prevent the mould corruption of food, keeps the color, smell and taste of food.Vacuum-packed technique has been widely used in the food service industry, and fresh-keeping effect is obvious to all.Also there is not a pressure cooker that can accomplish vacuum freshness retaining in the prior art.
Summary of the invention
Main purpose of the present utility model is: the vacuum freshness retaining pressure cooker that a kind of food spoilage speed that slows down is provided for the user.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of vacuum freshness retaining pressure cooker, has a pot body, pot cover, handle, only drive safety valve on the valve seat being provided with on the pot cover to be installed in, it is characterized in that: offer groove on the valve rod of only driving safety valve, sealing ring is installed in groove, sealing ring cooperates with the holder shoulder seal of valve seat; Maybe can control the dop structure that valve rod falls.
The technical solution of the utility model can also be further perfect:
As preferably, described dop structure is to be arranged at the draw-in groove of valve rod head and the shift fork that matches with draw-in groove, described shift fork be installed in handle on a spring push button link to each other.
As preferably, described dop structure is to be arranged at the draw-in groove of valve rod head and the groove dop that matches with draw-in groove, and described groove dop is enclosed within the valve rod outside.
As preferably, described dop structure is to be arranged at the external screw thread of valve rod head and the tapped screw thread dop that matches with external screw thread.
The beneficial effects of the utility model are: when food is boiled, be full of steam in the pressure cooker, only block the valve port of stopping valve this moment, along with kettle temperature descends, steam condenses, and food is in vacuum or the inferior vacuum environment in the pot, can guarantee that pot interior food never degenerates in 24 hours.Therefore, the utility model also can carry out fresh-keepingly to food except the repertoire that possesses the usual pressure pot, can effectively improve user's quality of life, obviously reduces the food waste phenomenon.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is a kind of safety valve and fit structure enlarged drawings only opened;
Accompanying drawing 3 is that another kind is only opened safety valve and fit structure enlarged drawing;
Accompanying drawing 4 is that another only opens safety valve and fit structure enlarged drawing.
The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
As Fig. 1-vacuum freshness retaining pressure cooker shown in Figure 4, have pot body 5, pot cover 2, handle 4 is only driven safety valve 3 on the valve seat 31 being provided with pressure valve 1 on the pot cover and being installed in.
Embodiment 1: as shown in Figure 2, offer groove one on valve rod 32 tops of only driving safety valve 3, be used to install sealing ring 7, sealing ring cooperates with the holder shoulder of valve seat 31, plays sealing function.Sealing ring adopts nontoxic rubber ring, when the pot internal gas pressure is lower than safe opening air pressure (such as the 40KPa that sets), only opens safety valve valve rod 32 and descends automatically, and sealing ring promptly touches with the holder shoulder grafting of valve seat 31, and the gap between valve rod and the bleeder port is blocked.When pressure in the pot continued to descend, atmospheric pressure was pushed down sealing ring, made the pot internal and external environment by isolated, and outside air can't enter in the pot, and food just is not easy to go bad in the pot.
Embodiment 2: offer groove one on the top of only opening safety valve 3 valve rods 32, a spring push button is installed on handle 4, spring is connected with a shift fork structure, and the size of shift fork matches with groove.When the pressure cooker internal gas pressure rises to a certain degree, stopping valve valve rod 32 rises, the pressure cooker sealing, the shift fork structure travels forward under the pressure effect of spring, combines with groove on the valve rod, and shift fork adopts taper shift fork structure, make shifting fork mechanism easily and groove fit, can guarantee that again valve rod is thus lifted to extreme position (valve rod only rises to extreme position just can play sealing function), have only push button that valve rod can descend to pusher.This mode realizes that pot inner air and outer air is isolated, carries out fresh-keeping to food.
Embodiment 3: as shown in Figure 4, in the head design of only opening safety valve 3 valve rods 32 external screw thread is arranged, be sleeved on the outside of valve rod 32 with the screw thread dop that adopts internal thread.Rise to a certain degree at the pressure cooker internal gas pressure, after valve rod 32 rises, put the screw thread dop, make it after pot inner pressure descends, because the effect of screw thread dop, valve rod 32 can not fall, and only after the screw thread dop shirked, valve rod 32 could fall, this is in vacuum or the inferior vacuum environment pot interior food, and food just is not easy to go bad.
Claims (4)
1. vacuum freshness retaining pressure cooker, has a pot body, pot cover, handle, only drive safety valve on the valve seat being provided with on the pot cover to be installed in, it is characterized in that: the dop structure that the sealing ring that can cooperate with the holder shoulder seal of valve seat or control valve rod fall is housed on the valve rod of only driving safety valve.
2. vacuum freshness retaining pressure cooker according to claim 1 is characterized in that: described dop structure is to be arranged at the draw-in groove of valve rod head and the shift fork that matches with draw-in groove, described shift fork be installed in handle on a spring push button link to each other.
