Vacuum leakproof structure of ash jar

The present invention relates to a technical field of the structure of an ashes tank, and particularly relates to a vacuum leakproof structure of an ashes tank which has good vacuum sealing property and is simple and convenient to manufacture and can greatly reduce the defect rate and cost.

The conventional vacuum structure of the ashes can be as shown in Taiwan Patent No. 501480 (the following symbols are based on the original indications of the previous case, so the case is not separately indicated in the symbol description), and the main system is the inner cover. The top surface of the fifth surface is provided with a through hole 53 penetrating to the bottom and a passage 54 penetrating into the through hole, and a plug 55 is screwed into the through hole 53. Therefore, as long as the plug 55 is slightly unscrewed upward, the passage 54 communicates with the accommodating space 41 of the inner tank body 4 through the through hole 53, and the air in the accommodating space 41 is extracted by the passage 54 and then The plug 55 is screwed down to the interface of the passage 53 and the through hole 53 so that the through hole 53 cannot communicate with the accommodating space 41 through the passage 54, so that a vacuum can be formed in the accommodating space 41. The state, in order to achieve the purpose of avoiding moisture in the interior of the ashes installed.

However, since the inner lid 5 of the conventional canister has a relatively large volume with respect to the through hole 53 and the passage 54, the hole is made to be very small on the inner cover 5 of the metal material having a high hardness. When the through hole 53 and the passage 54 are in the clamp It is inconvenient to hold, move and position, and it also needs to be drilled with a relatively small outer diameter drill bit, and such a small diameter drill bit is to be drilled on the harder inner cover 5 and When the passage 54 is used, it is easy to cause cracking and damage, so the processing and processing is more troublesome and inconvenient, and the work efficiency cannot be improved, and thus the economic efficiency is not met. Moreover, the use of a thread to lock the venting hole is likely to result in poor vacuum sealing due to poor precision of the threading process.

In addition, if the through hole 53 and the passage 54 are applied to the stone cover which is not hard, the damage of the drill bit can be reduced, but the stone material is brittle, so that it is drilled. When the small through holes 53 and the passages 54 are prone to cracking, the entire outer can is unusable and wasteful, and the disadvantage rate and cost are relatively increased. Moreover, it is not easy to machine the thread for the hole plug 55 to be screwed into the through hole 53, and even if it can be processed, the screw tightness with the hole plug 55 cannot be extremely high, so The vacuum sealing effect is greatly reduced. If the outer diameter of the through hole 53 and the passage 54 are increased to improve the above problem, and then the rubber plug or the valve body is fitted, the through hole 53 and the plug or valve may be used again. The combined area of the body is increased, so that the tightness of the two is relatively reduced, and the vacuum sealing effect is still relatively poor.

The vacuum leakproof structure of the conventional ash can has problems such as poor vacuum sealing property and difficulty in production, and high defect rate and cost.

The present invention provides a vacuum leakproof structure for an ash can, comprising a can body, a can lid, a sealing gasket, a septum, a valve body and a leak-proof patch. Wherein, the can body is engraved with stone, and has a groove facing upward to accommodate the ashes. The can lid is made of stone, glass, and glazed, and is covered on the can body to cover the opening of the cavity. The top surface of the can lid has a recess, and the bottom surface of the groove has a perforation penetrating to the bottom surface of the can lid. The sealing gasket is disposed between the opening of the can body and the joint surface of the can lid. The spacer is incorporated in the recess to cover the through hole, and the spacer has a coupling hole and a plurality of air holes therethrough. The valve system has a coupling post, a fixing portion and an elastic piece. The bonding column is embedded in the bonding hole. The fixing portion is disposed at a bottom end of the binding post, and an outer diameter is larger than the binding post to be disposed on a bottom surface of the spacer. The elastic piece is disposed at a top end of the binding post and is located on a top surface of the spacer and covers the plurality of air holes, and the elastic piece is elastically turned up to open the plurality of air holes. The leakage preventing patch is attached to the valve body and covers the valve body.

The vacuum leakproof structure of the ash can provided by the present invention can be designed by the structure of the valve body and the spacer and the leakage preventing patch, so that when the air in the cavity of the can body is taken out, The elastic piece of the valve body can be elastically opened upward to open the plurality of air holes, and when the air is stopped, the elastic piece can elastically cover the plurality of air holes immediately, and then the adhesive surface of the leakage preventing piece is attached to the valve body and Covering the valve body, it has the advantages of simple and convenient operation and better vacuum sealing and leakage prevention effects. In particular, the arrangement of the spacer enables the perforation drilled in the can lid to have a larger inner diameter, so that the processing is simpler and less prone to the defect rate, and In addition, it can improve the problem that the conventional drill bit is easy to be damaged when the drill bit is too small or when the can lid is drilled. In particular, it is very simple and easy to fabricate the joint hole and the plurality of pores on the separator, and the valve body can be integrally formed, and the leak-proof patch can ensure vacuum. Therefore, the overall production is relatively simple and convenient, and can greatly reduce the non-performing rate and cost.
