Description

A kind of electric pressure appliance without in aerofluxus press safety guard

Technical field

This utility model relate to a kind of solve heat tape pressure type utensil without in aerofluxus press safeguard protection dress Put.

Background technology

Chinese patent CN202010034U discloses a kind of pressure cooking appliance float in 2011-10-19 Valve, including float spool, float valve seat, security activity latch fitting and sealing ring, described float valve seat close-fitting Being combined in the upper cover of pressure cooker, described float spool is slidably fitted in float valve seat, and described safety is lived Dynamic latch fitting is positioned at the top of float spool and is connected with upper cover, and described sealing ring is in being respectively provided with out up and down The bowl-shape flexible body of mouth, and upper shed greatly big opening end, under shed is little for osculum end；Its osculum end is with floating The lower end close-fitting of sub-spool, its big opening end and float valve seat or upper cover close-fitting.

If heat tape pressure type product maloperation after upper pressure, user's upper cap assembly of outwarding winding may cause sternly Weight potential safety hazard.This hidden danger is mainly had following two to protect by prior art:

1. some product is stiff plus float spool and sealing ring, between float spool and float valve seat Exist gap, easily by food disintegrating slag run into so that the sealing effectiveness of sealing ring is bad.

2. use the technical scheme of aforementioned Chinese patent CN202010034U, although the program does not have food Disintegrating slag run into, but only reset instability by sealing ring resilience, and this sealing ring center has through hole easily to make Seal failure, float valve core movement is become to have some setbacks or block.

Utility model content

For the above-mentioned deficiency of prior art, according to embodiment of the present utility model, it is desirable to provide Yi Zhongxing Can stable, simple in construction without pressing safety guard in aerofluxus, it is intended to overcome protection in prior art to tie The part being configured to do not resets, moving has some setbacks, has the antihygienic defect of food disintegrating slag.

According to embodiment, a kind of electric pressure appliance that this utility model provides without pressure safeguard protection in aerofluxus Device, including float spool, float valve seat, spring, sealing ring, steam cover plate and push jack, its innovation Point is, being provided with groove position bottom steam cover plate, sealing ring is placed in described groove position；Float valve seat Inside is provided with through hole, spring and float spool and coaxially assembles and be assemblied in inside float valve seat, float-controlled valve Core can move up and down in through hole, and float valve seat is assemblied in the intrinsic pressure tight seal in steam lid panel notches position； In gearing, cap assembly carries out the push jack of folding lid and is provided with through hole；When the pressure in electric pressure appliance reaches to set During pressure, float spool and sealing ring are carried out stop through through hole to push jack by jack-up, float spool, push away Sheet cannot interlock cap assembly and carry out folding lid operation；When the pressure in electric pressure appliance is less than setting pressure Time, float spool is resetted downwards by the elasticity that spring and sealing ring combine, and push jack interlocks upper cap assembly and enters Row folding lid operates.

Relative to prior art, this utility model possesses following characteristics:

This utility model uses float valve seat screw thread to screw compression round shape atresia sealing ring, more air-tightness； Rather than Chinese patent CN202010034U such use through hole sealing ring laminating assembling, compress easily without external force Gas leakage.

This utility model uses float spool to use the mechanical type contact of outer side surface and side, push jack hole to join Close, utilize face to realize stop with the cooperation that contacts in face, more stability；Chinese patent CN202010034U The easy resilience of technical scheme reset instability, easily cause seal failure, float valve core movement has some setbacks, Or block.

This utility model uses float spool to move down the elastic reset using spring and rubber to combine that resets, More accuracy；Rather than as Chinese patent CN202010034U, it is used alone sealing ring elastic reset.

Fig. 2 is the partial enlarged drawing of Fig. 1.

Profile when Fig. 3 is that during this utility model is implemented, product runs；

Fig. 4 is the partial enlarged drawing of Fig. 3.

Wherein: (1) is float spool, (2) are float valve seat, and (3) are spring, and (4) are sealing ring, (5) being steam cover plate, (6) are push jack, and (6-1) is push jack through hole.

Detailed description of the invention

Below in conjunction with the accompanying drawings and specific embodiment, this utility model is expanded on further.These embodiments should be managed Solution is used only for this utility model being described rather than limiting protection domain of the present utility model.Reading After the content that this utility model is recorded, this utility model can be made various change by those skilled in the art Or amendment, these equivalences change and modifications and fall into this utility model claim limited range equally.

With reference to Fig. 1-Fig. 4, the electric pressure appliance that this utility model preferred embodiment provides without pressure in aerofluxus Safety guard, mainly includes float spool 1, float valve seat 2, spring 3, sealing ring 4, steam Cover plate 5 and push jack 6, wherein:

As shown in Figure 1-2, being provided with groove position bottom steam cover plate 5, sealing ring 4 seals for round shape atresia Circle, sealing ring 4 is placed in described groove position；Float valve seat 2 is internal is provided with through hole, spring 3 He Float spool 1 coaxially assembles, and is then assemblied in float valve seat 2 internal, and float spool 1 can be at through hole Interior up and down motion, float valve seat 2 Screw assembly is intrinsic pressure tight seal 4 in steam cover plate 5 groove position, reaches Sealing function, now float spool 1 still can upper and lower smooth and easy motion in through hole, solve because of food materials Adhesion float spool 1 and the problem that can not normally uncap.

As shown in Figure 3-4, cap assembly can be interlocked and carry out the push jack 6 of folding lid and be provided with through hole 6-1, work as product When product pressure reaches authorized pressure, float spool 1 and the sealing ring 4 such as direction of arrow, by jack-up, now float Sub-spool 1 carries out stop through through hole 6-1 to push jack 6, and push jack 6 cannot interlock cap assembly and open Closing lid, it is achieved the safeguard protection can not uncapped when having pressure.When product pressure is below authorized pressure, Float spool 1 is resetted downwards by the elasticity that spring 3 and sealing ring 4 combine, i.e. float spool 1 is cancelled Stopping effect to push jack 6, push jack 6 can interlock cap assembly smoothly and carry out folding lid.

When being embodied as this utility model, stop-motion body float spool can be pin or other shapes.

When being embodied as this utility model, the stop of stop-motion body float spool and push jack can be face with face, Point and face or other assembling forms.

When being embodied as this utility model, stop-motion body float valve core movement can be that elastic reset, gravity are multiple Position or other forms.

When being embodied as this utility model, the fixing of float valve seat can be to be screwed, it is also possible to is it His reliable fixed form.

When being embodied as this utility model, sealing ring can be round shape, it is also possible to be other shapes.
