Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vacuum bags, in particular to a zipper combination device for vacuum bags. Background Art
[0002] A vacuum bag is a bag that evacuates the air inside the bag through an air extractor to achieve sealing, moisture-proof, anti-oxidation, and long-term freshness preservation. The vacuum bag evacuates all the air, reducing the influence of substances such as oxygen and moisture on food. Therefore, the vacuum bag can maintain the freshness of food, effectively extend the freshness preservation period, and prevent the growth of bacteria. A vacuum pump is required during the process of evacuating the air from the vacuum bag.
[0003] However, traditional vacuum bags have the following disadvantages:
[0004] When traditional vacuum bags perform vacuum treatment on their own, a vacuum extraction pipe is inserted through themselves to perform a vacuum pumping operation on the gas inside the vacuum bag, and then the gas is discharged externally. Then, the vacuum bag is buckled successively, and finally the vacuum pipe is taken out. After the pipe is taken out, there may be a phenomenon that there is a gap with the diameter of the pipe at the zipper of some vacuum bags. In this way, the pipe is convenient to be taken out from the vacuum bag, but the vacuum bag cannot complete vacuum sealing. By adding buckling equipment, the sealing cost of the vacuum bag is increased, and the additional buckling equipment is easily abandoned and cannot be found, which cannot meet the usage requirements of people. Content of the Utility Model
[0005] The purpose of the utility model is to provide a zipper combination device for vacuum bags to solve the problem that when traditional vacuum bags perform vacuum treatment on their own, a vacuum extraction pipe is inserted through themselves to perform a vacuum pumping operation on the gas inside the vacuum bag, and then the gas is discharged externally. Then, the vacuum bag is buckled successively, and finally the vacuum pipe is taken out. After the pipe is taken out, there may be a phenomenon that there is a gap with the diameter of the pipe at the zipper of some vacuum bags. In this way, the pipe is convenient to be taken out from the vacuum bag, but the vacuum bag cannot complete vacuum sealing. By adding buckling equipment, the sealing cost of the vacuum bag is increased, and the additional buckling equipment is easily abandoned and cannot be found, which cannot meet the usage requirements of people as mentioned in the above background art.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A zipper combination device for a vacuum bag, including a vacuum pump housing, the bottom end of the vacuum pump housing is fixedly communicated with a suction nozzle housing, the bottom end of the suction nozzle housing is provided with a suction port, the top end of the vacuum pump housing is provided with a movable opening, and a zipper sealing mechanism is slidably connected inside the movable opening. The zipper sealing mechanism includes a pull rod and a sealing head. The top end of the pull rod is rotatably connected with a rotating shaft, the top end of the rotating shaft is fixedly connected with the bottom end of the sealing head, and a first zipper groove is provided at the top end of the sealing head.
[0007] Preferably, grooves are formed on both sides of the bottom end of the sealing head, and the user can take the sealing head through the grooves.
[0008] Preferably, a sealing plug is fixedly installed at the bottom end of the pull rod. The sealing plug is slidably connected to the vacuum pump housing. During the sliding process of the pull rod, the sealing plug slides along the vacuum pump housing. During the sliding process of the sealing plug, an attraction force is generated, so that the gas in the vacuum bag is inhaled into the vacuum pump housing through the suction nozzle housing through the suction port, and finally discharged through the vacuum pump housing.
[0009] Preferably, four sliding blocks arranged in a rectangle are fixedly installed on the side surface of the pull rod. All four sliding blocks are slidably connected to the movable opening. During the process of the user pulling the pull rod, the sliding blocks are driven to slide along the movable opening.
[0010] Preferably, the vacuum pump housing is cylindrical.
[0011] Preferably, a pressing piece is installed at the top end of the sealing head. A second zipper groove is formed at the bottom end of the pressing piece. The first zipper groove and the second zipper groove are arranged correspondingly. When the user presses the pressing piece, the second zipper groove approaches the first zipper groove. The first zipper groove and the second zipper groove cooperate with each other to squeeze and seal the sealed part of the vacuum bag.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] By setting a zipper sealing mechanism, the zipper sealing mechanism is assembled on the traditional vacuum pump housing. The user drives the suction nozzle housing to extract the gas in the vacuum bag by pulling the pull rod. When the vacuum bag is not firmly sealed, by pressing the pressing piece, the zipper grooves on both sides cooperate with each other to complete the sealing of the vacuum bag, meeting the usage requirements of people;
[0014] The specific operation of the vacuum pump to extract vacuum is as follows: during the sliding process of the pull rod, the sealing plug is driven to slide along the vacuum pump housing. During the sliding process of the sealing plug, an attraction force is generated, so that the gas in the vacuum bag is inhaled into the vacuum pump housing through the suction port through the suction nozzle housing, and finally discharged through the vacuum pump housing, which is simple and convenient.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.
[0021] Please refer to Figures 1-4 , the present invention provides a zipper combination device for a vacuum bag, including a vacuum pump housing 1. The bottom end of the vacuum pump housing 1 is fixedly communicated with a nozzle housing 2. The bottom end of the nozzle housing 2 is provided with a suction port 5. The top end of the vacuum pump housing 1 is provided with a movable opening 4. A zipper sealing mechanism 3 is slidably connected inside the movable opening 4. The zipper sealing mechanism 3 includes a pull rod 31 and a sealing head 33. The top end of the pull rod 31 is rotatably connected to a rotating shaft 37. The top end of the rotating shaft 37 is fixedly connected to the bottom end of the sealing head 33. The top end of the sealing head 33 is provided with a first zipper groove 34.
[0022] Grooves 35 are provided on both sides of the bottom end of the sealing head 33. The user takes the sealing head 33 through the grooves 35.
[0023] A sealing plug 36 is fixedly installed at the bottom end of the pull rod 31. The sealing plug 36 is slidably connected with the vacuum pump housing 1. During the sliding process of the pull rod 31, the sealing plug 36 is driven to slide along the vacuum pump housing 1. During the sliding process of the sealing plug 36, an attraction force is generated, so that the gas in the vacuum bag is inhaled into the vacuum pump housing 1 through the suction port 5 and the nozzle housing 2, and finally discharged through the vacuum pump housing 1.
[0024] Four sliding blocks 32 arranged in a rectangle are fixedly installed on the side surface of the pull rod 31. All four sliding blocks 32 are slidably connected with the movable opening 4. During the process of the user pulling the pull rod 31, the sliding blocks 32 are driven to slide along the movable opening 4.
[0025] The vacuum pump housing 1 is cylindrical.
