Description

A kind of inhalator jar release bottom

Technical field

Inhalator jar technical field is the utility model is related to, specifically a kind of inhalator jar release bottom.

Background technology

In the life of modernization, aerosol spray almost turns into articles for daily use indispensable in people's life, and inhalator jar is made For the carrier of aerosol spray, belong to pressure vessel, its security reliability depends primarily on its resistance to pressure, and the hair of inhalator jar at present Exhibition trend is the pressure requirements more and more higher to inhalator jar, but inhalator jar is by conditions such as high temperature when being influenceed, tank interior The bulbs of pressure become danger that is big, or even can causing blast, for safety guarantee, it is necessary to which inhalator jar has the function of automatically unloading, Release can be carried out in time when the pressure being subject to reaches certain limit, prevent explosion danger.

The content of the invention

In view of the shortcomings of the prior art, the utility model provides a kind of inhalator jar bottom with automatic pressure-relief function.

The technical solution of the utility model is：A kind of inhalator jar release bottom, including main body and annular block, the main body Section be in connect annular block towards the raised arcuate structure of tank body, the edge-smoothing of main body, it is characterised in that：The main body The circular convex being provided centrally with towards tank interior, be provided with circular convex and unload beading, unload beading along circular convex The center of circle direction extension, the bending structure to tank body external concavity for unloading beading and being formed for the stretched punching press of main body.

The beading that unloads is provided with bending angle, and the thickness at bending angle is less than the thickness of main body.

It is described to unload that beading extends linear structure, arcuate structure, " S " type structure in circular convex or other are smooth Curvilinear structures.

The depth for unloading beading depression tapers into along the center of circle direction away from circular convex, so that unloading beading End is in smoothing junction with circular convex.

The beading that unloads is arranged in the muscle groove being recessed to outside tank body being engaged with unloading beading profile.

The circle centre position that circular convex is extended to and unloads beading, pressure sensitive scope is extended to main center, while Solvent is leaked at center when release, strengthen release effect.

The beading that unloads is provided with more than 3, and unloads beading and extend to around the center of circle of circular convex, and adjacent 2 are unloaded Smooth connection forms the polygonized structure of closing around the center of circle between beading.

The beneficial effects of the utility model are：

Realize that condition of high voltage ftractures automatically by breakaway poing of the beading formation inhalator jar under ultra-high pressure condition that unload of setting Pressure relief, effectively prevent high pressure explode danger, play a part of security protection, unload beading set pointedly be distributed In the stress concentration direction of aerosol pot cover, there is higher sensitivity, the utility model is not required to increase other raw materials, cost is low, Outward appearance is beautiful, practical.

Brief description of the drawings

Fig. 1 is front view of the present utility model,

Fig. 2 is top view of the present utility model,

Fig. 3 is the schematic cross-section that the utility model unloads beading,

Wherein, the block of 1- annulars, 2- main bodys, 3- circular convex, 4- unload beading, 5- muscle groove, 6- bendings angle.

Embodiment

Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings：

As shown in Figure 1 to Figure 3, a kind of inhalator jar release bottom, including main body 2 and annular block 1, the main body 2 are cut Face is in connect annular block 1 towards the raised arcuate structure of tank body, the edge-smoothing of main body 2, it is characterised in that：The main body 2 The circular convex 3 being provided centrally with towards tank interior, be provided with circular convex 3 and unload beading, unload beading 4 along circular convex The center of circle direction extension in face 3, the bending to tank body external concavity unloaded beading 4 and formed for 2 stretched punching press of main body Structure.

The beading 4 that unloads has bending angle 6, and the thickness at bending angle 6 is less than the thickness of main body 2.

It is described to unload that beading 4 extends linear structure, arcuate structure, " S " type structure in circular convex 3 or other are smooth Curvilinear structures.

Further, the depth for unloading the depression of beading 4 tapers into along the center of circle direction away from circular convex 3, from And make end and the smooth connection of circular convex 3 for unloading beading 4.

Further, the beading 4 that unloads is arranged on the muscle groove 5 being recessed to outside tank body being engaged with unloading the profile of beading 4 It is interior, effectively avoid the bending angle 6 for unloading beading 4 from easily being reduced the phenomenon of inhalator jar compression capability by foreign impacts and abrasion.

In some embodiments, the circle centre position for unloading beading 4 and extending to circular convex 3, pressure sensitive scope is expanded Greatly to the center of main body 2, while solvent is leaked at center when release, strengthen release effect.

In some embodiments, the beading 4 that unloads is provided with more than 3, and unloads beading 4 and extend to circular convex 3 Around the center of circle, adjacent 2 are unloaded the polygonized structure that smooth connection between beading 4 forms closing around the center of circle, are unloading beading 4 The center of main body 2 is torn to form a larger relief port during rupture release, enable tank body internal solvent rapidly from Leaked in relief port, release speed is faster, ability is stronger, effect becomes apparent from.

The beading 4 of the present utility model that unloads is the bending corner structure that main body 2 is formed to tank body external concavity, unloads the folding of beading 4 Stress suffered by bending part of the thickness of bent angle 6 less than the thickness of main body 2 and at bending angle 6 is maximum, turns into the quick of pressure sensitive Sensillary area, and the breakaway poing of release, in the case where inhalator jar is gone beyond the limit high pressure, it is relatively thin unload beading 4 and broken through release The solvent inside inhalator jar is released, reaches automatically unloading, safing effect.

Simply illustrate principle of the present utility model and most preferred embodiment described in above-described embodiment and specification, do not taking off On the premise of the spirit and scope of the utility model, the utility model also has various changes and modifications, these changes and improvements Both fall within claimed the scope of the utility model.
