Abstract

The utility model discloses a vacuum pot which comprises a cover body 1 and a pot body 2 which are in scarf joint, wherein a sealing washer 21 is arranged between the cover body 1 and the pot body 2 to prevent air from leaking. The utility model is characterized in that an air ventilation chamber 11 and a longitudinal circular hole passage 16 which is communicated with the cover body 1 are arranged on the cover body 1. A lower cover 12, a control valve 13 and a valve plate 14 are respectively assembled in the air ventilation chamber 11. The upper part of the air ventilation chamber 11 is covered by an upper cover 15, and the upper part of the whole body is assembled outside by a shield body 17. An air pumping post 3 is penetrated in the circular hole passage 16, and the inner side of the head end 31 is provided with a convex ring 32. A plurality of air holes 33 are arranged between the air pumping post 3 and the convex ring 32, and an O-shaped ring 34 is sheathed between the air pumping post 3 and the convex ring 32. The outer end of the O-shaped ring is combined with a handle 35 which is arranged outside the shield body 17. An air intake lever 36 has a two-section structure or an integral structure, and a spring 37 is sheathed in the center section of the air intake lever. The air intake lever 36 is arranged in the air pumping post 3, and both ends of the air intake lever 36 respectively penetrate through the air pumping post 3. The front end of the air intake lever is closely connected with the inner hole of the air pumping post 3. The utility model is convenient to operate and can avoid the situation that the faulty touch leads to the occurrence of the ineffective degree of vacuum.

Description

Vacuum reservoir

Technical field

The utility model relates to a kind of vacuum reservoir that is used to preserve food or article.

Background technology

At present, known have a multiple different vacuum reservoir, provide preferable food preservation or article to preserve, and common vacuum reservoir structure includes a tank body and a lid usually, and the realization of its vacuum is to be provided with an extraction sector in cap portion, uses the air extraction in the jar, one admission gear independently is set on lid in addition, air is entered by this position, remove vacuum, can open jar and take article.This common constitution is owing to bleed and air inlet is diverse location setting on lid, and it is comparatively complicated therefore to construct nature, and destroys the intensity of lid easily, and must utilize the action of bleeding of the extraction sector of an individual member, and is quite inconvenient.In addition, common air intake structure is to protrude from the lid below, so regular meeting takes place have air to run in the jar because of false touch causes admission gear's action, makes the degree of vacuum forfeiture, causes former disabler.

The utility model content

The purpose of this utility model is will solve to bleed in the existing vacuum reservoir structure to be arranged on the diverse location of lid with air intake structure, and causes the problem of complex structure, operation inconvenience and easy false touch admission gear forfeiture degree of vacuum.

The utility model provides a kind of vacuum reservoir, this vacuum reservoir can overcome the shortcoming that above-mentioned common vacuum reservoir exists, the utility model includes a lid and a tank body, both tablings, and be located at tightening seal washer and prevent that therebetween gas from oozing dew, it is characterized in that, lid is provided with the transverse circular duct that an airiness chamber and communicates, and in the indoor combination respectively of airiness one lower cover is arranged, and has inserted a control cock and a valve plate, top is with the loam cake combination, outside integral upper is combined in a cover body; One post of bleeding is arranged in the circular duct, and the inboard slightly of its head end is provided with a bulge loop, is provided with several pores between the two, and is arranged with an O type ring, and its outer end is combined with the leader, is positioned at the outside of cover body; One air intake lever is the structure of two sectional type, mutually combines to be one, and a spring is sleeved on middle section position, and air intake lever is arranged on the inside of the post of bleeding, and two ends are piercing in the post of bleeding respectively, and the endoporus of the front end and the post of bleeding forms tightlock status.

In addition, air intake lever can be the integrated single body of rod, and spring housing is combined in its middle section position.

Post and the air intake lever of bleeding of the present utility model is combined as a whole, cooperate the airiness chamber, make the bleed twitch back and forth of post of its utilization, gas in the jar is outwards extracted out, form vacuum, in addition, air intake lever is located in the post of bleeding, can the indoor valve plate of simple and easy ejection airiness, finish the air inlet action, because it is Construction integration, be can handled easily and the situation of avoiding false touch to cause degree of vacuum to lose efficacy take place.

The specific embodiment

See also Fig. 1, shown in Figure 2, a lid 1 and the tank body 2 of including of the present utility model, but tabling, and be located at tightening seal washer 21 and prevent that therebetween gas from oozing dew, it is characterized in that lid 1 is provided with the transverse circular duct 16 that an airiness chamber 11 and communicates, combination has a lower cover 12 respectively in airiness chamber 11, inserted a control cock 13 and a valve plate 14, top is with loam cake 15 combinations, outside integral upper is combined in a cover body 17 again; One post 3 of bleeding is arranged in the circular duct 16, and the inboard slightly of its head end 31 is provided with a bulge loop 32, is provided with several pores 33 between the two, and is arranged with an O type ring 34, and its outer end then in conjunction with leader 35, is positioned at the outside of cover body 17; One air intake lever 36 is the structure of two sectional type, and mutually combining is one, so that a spring 37 is sleeved on middle section position, also can be the integrated body of rod, it is arranged on the inside of the post 3 of bleeding, and its two ends are piercing in the post 3 of bleeding respectively, and the endoporus of the front end and the post 3 of bleeding forms tightlock status.

When bleeding, can utilize the action that handle 35 application of forces are pulled out and are pressed into to finish, as shown in Figure 3, Figure 4, when pulling out when bleeding post 3, its O type ring 34 can move on the pore 33, and sealing, therefore by pulling force, the air in making jar can be in Fig. 3 the direction of arrow, via the gap of airiness chamber 11 and the centre hole of control cock 13, make valve plate 14 inclinations one angle, and flow in the circular duct 16.Be pressed into when bleeding post 3 when the application of force in addition, because of can making valve plate 14, difference of pressure covers the centre hole of control cock 13, the O type ring 34 of bleeding simultaneously on the post 3 can move backward, expose pore 33, so when the post 3 of bleeding moves inward, air can enter pore 33 as the direction of arrow among Fig. 4, and discharges outside from the perforate in the outside.So repeatedly pull out and be pressed into action, a jar interior air is reduced, until forming the state that is close to vacuum.

When desire is opened vacuum reservoir, must give air inlet earlier, see also Fig. 5, Fig. 6, shown in Figure 7, the utility model can directly be suppressed the outer end of air intake lever 36, and its inner is inwardly moved, and ejection is to valve plate 14, make its inclination and expose the centre hole of control cock 13, just this moment, the air natural energy entered in the jar, as the direction of arrow among Fig. 6, Fig. 7, make it recover air pressure, and jar is to open.

In sum, will bleed post and air intake lever of the utility model is nested with together, is can simplified structure, is convenient to make, and increases the intensity of lid; In addition, when using, also can avoid the shortcoming of false touch.
