In such a manner, theair pipe 221 is extended through anair hole 201 of thebase 20 and is connected to theair guide hole 220 of theair bag 22 so that the air is filled through theair pipe 221 into theair bag 22. When in use, the air is filled through theair pipe 221 into theair bag 22 so that theair bag 22 is filled with air and is inflated and expanded upward to push thesealing bar 21 upward. Thus, thesealing bar 21 is lifted to abut a sealing strip located above thesealing bar 21 so as to press and seal a packaging bag so that the packaging bag is clamped between thesealing bar 21 and the sealing strip. Then, thesealing module 2 is heated so that the packaging bag is heated to proceed a sealing and packaging process. In addition, the O-ring 24 is mounted on theair pipe 221 to provide an air-tight function so as to prevent the air from being leaked outward from theair pipe 221. Thus, thesealing module 2 has a simplified construction without having many parts so that thesealing module 2 is assembled easily and quickly. In addition, thesealing module 2 is disassembled quickly so that thesealing module 2 can be cleaned easily. Further, thesealing module 2 has few parts so that thesealing module 2 is not easy to fail, thereby enhancing the quality and working efficiency of thesealing module 2. - Referring to
FIGS. 4 and 5 with reference toFIGS. 2 and 3 , the length of thesealing bar 21 corresponds to the distance between theguide posts 23 so that the two opposite ends of thesealing bar 21 are mounted on theguide posts 23 respectively by guidance of themounting groove 210 at each of the two opposite ends of thesealing bar 21. Thesealing bar 21 is initially disposed at an inclines state, with themounting groove 210 of thesealing bar 21 being mounted on one of theguide posts 23. Then, one of the two opposite ends of the sealingbar 21 is pushed toward one of the guide posts 23 as shown inFIG. 4 so that thearcuate positioning recess 211 of one of the two opposite ends of the sealingbar 21 abuts the respective guide post 23 as shown inFIG. 5 . Then, the other one of the two opposite ends of the sealingbar 21 is mounted on the other one of the guide posts 23 as shown inFIG. 4 , with thearcuate positioning recess 211 of the other one of the two opposite ends of the sealingbar 21 abutting therespective guide post 23, so that each of the guide posts 23 is received in the mountinggroove 210 of the sealingbar 21 and is locked in the respectivearcuate positioning recess 211 of the sealingbar 21. Thus, the sealingbar 21 is located between the guide posts 23 and cannot be displaced any more. On the contrary, when the user wishes to replace the sealingbar 21, one of the two opposite ends of the sealingbar 21 is pushed toward one of the guide posts 23. Then, the other one of the two opposite ends of the sealingbar 21 is lifted to detach from the other one of the guide posts 23 so that the sealingbar 21 is disposed at an inclines state. Thus, the sealingbar 21 can be detached from the guide posts 23 easily and quickly, without aid of any hand tool. - Accordingly, the sealing
bar 21 is located between the guide posts 23 by guidance of the mountinggroove 210 and by positioning of thearcuate positioning recess 211, so that the sealingbar 21 is locked onto and detached from the base 20 easily and quickly. In addition, the sealingbar 21 can be detached from the guide posts 23 easily and quickly, without aid of any hand tool, so that thesealing module 2 is disassembled quickly and can be cleaned easily. Further, thesealing module 2 has few parts so that thesealing module 2 is not easy to fail, thereby satisfying the working requirement of the operator. Further, thesealing module 2 has a simplified construction without having many parts so that thesealing module 2 has a lower cost of fabrication to provide an economic benefit to the consumer. Further, thesealing module 2 has few parts and has a flat and even surface without clearance and dead corner, so that dust or dirt will not be accumulated in the parts of thesealing module 2, thereby facilitating maintenance and enhancing the lifetime of thesealing module 2. - Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
