Description

Technical Field

[0001] The utility model relates to the technical field of vacuum sealers, in particular to a vacuum sealer with a visible structure. Background Art

[0002] At present, the working principle of the existing vacuum sealers in the prior art is to clamp the opening of the bag by using an upper cover and a lower cover, then extract the air in the bag through a vacuum pump, and finally seal the bag by using a hot melting method. However, all the existing vacuum sealers have a common drawback: since the bag needs to place the opening between the upper cover and the lower cover, and the upper cover is a non-transparent part, the user cannot judge whether the opening of the bag is placed in the correct position, and only knows until the final vacuum extraction fails.

[0003] For this reason, relevant technical personnel have carried out research and development. For example, a vacuum pump disclosed in a utility model with a Chinese patent application number of CN201721737224.6 includes an upper cover and a base that are axially connected. A working cavity is provided on the base, and a long strip-shaped through hole is opened directly above the working cavity on the upper cover. A transparent cover is inserted in the through hole. The transparent cover includes a cover body and a mounting seat that are integrally connected. The mounting seat is fixedly arranged at the lower end of the upper cover. The cover body is inserted in the through hole. A light strip mounting strip is arranged on the side of the mounting seat where the cover body is located, and a light strip is arranged on the light strip mounting strip. The light strip of the above structure is arranged on the mounting seat through the light strip mounting strip, and then fixed on the through hole of the upper cover by using the mounting seat. Its assembly process is complex and the production cost is high. Moreover, when the light strip is working, its light will directly irradiate outwards from the through hole, causing the user to be dazzled and affecting the use experience. Therefore, it is necessary to further improve. Summary of the Utility Model

Many specific details are set forth in the following description to facilitate a full understanding of the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0026] The present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0027] See Figures 1-9 , this vacuum sealer with a visible structure includes a first housing and a second housing. The first housing is hinged to open and close on the second housing. A through groove, a pressing strip 2, a light-emitting member 20, and a light-transmitting member 21 are provided on the first housing. Among them, the through groove is provided on the first housing in a vertically penetrating manner. The light-transmitting member 21 is provided on the through groove. The light-emitting member 20 is located on the side or inside of the light-transmitting member 21 and transmits light through the light-transmitting member 21. A vacuum pumping groove 3, a vacuum pump 4, and a heating member 5 are provided on the second housing. Among them, the air extraction end of the vacuum pump 4 is communicated with the vacuum pumping groove 3. The pressing strip 2 corresponds to the heating member 5, and the through groove corresponds to the vacuum pumping groove 3.

[0028] In this embodiment, the through groove, the vacuum pumping groove, and the vacuum pump 4 are used in cooperation to extract the air inside the bag, and then the cooperation of the pressing strip 2 and the heating member 5 is used to achieve hot melt sealing of the bag mouth. In addition, the light-emitting member 20 is arranged on the side or inside of the light-transmitting member 21 of the through groove, so that the light generated by the light-emitting member 20 during operation is transmitted through the light-transmitting member 21, facilitating the user to observe the internal working conditions of the through groove and the vacuum pumping groove even in a state of poor light. Moreover, the light-emitting member 20 is directly arranged on the first housing, and no auxiliary components are required during its assembly. The assembly process is simple and the production cost is low. In addition, since the light-emitting member 20 is placed on the side or inside of the light-transmitting member 21, the light generated by the light-emitting member 20 during operation will not directly irradiate the user, and its light emission is soft and will not cause the user to be dazzled, so as to improve the user experience.

[0029] In this embodiment, when the light-emitting member 20 is assembled, it can be located in front of, behind, on the left, on the right, on the bottom, or inside the light-transmitting member 21. Its assembly position is diverse, and the light generated by the light-emitting member 20 during operation passes through the light-transmitting member 21 and is transmitted in the direction of the through groove.

[0030] The through groove and the vacuum pumping groove 3 have the same shape and are both elongated. The shape of the light-transmitting member 21 is equivalent to that of the through groove. The light-emitting member 20 is a light strip or a lamp bead and is arranged on the front side along the long dimension direction of the light-transmitting member 21, thereby increasing the transmission amount of the illumination light.

[0031] The light-emitting component 20 is located on the front side of the light-transmitting component 21, and the illumination light generated by it irradiates towards the light-transmitting component 21 from the front to the back, and is transmitted through the light-transmitting component 21 into the through groove. Since the light-emitting component 20 is located on the front side of the light-transmitting component 21, the illumination light generated by the light-emitting component 20 during operation can only be emitted backward and will not directly irradiate the user.

[0032] The top of the light-transmitting component 21 is closed, and a light-transmitting lower opening 22 is provided at the bottom, and is interconnected with the lower opening of the through groove through the light-transmitting lower opening 22, thereby ensuring that the illumination light can irradiate into the through groove.

[0033] When the first housing and the second housing are hinged and closed, the light-transmitting lower opening 22 is interconnected with the opening of the evacuation groove 3. The illumination light located in the through groove enters the evacuation groove 3 through the light-transmitting lower opening 22, thereby enabling the illumination light to enter the inside of the through groove and the evacuation groove 3, so as to facilitate the user to observe the internal working conditions of the through groove and the evacuation groove.

[0034] The first housing includes a first upper cover 9 and a first bottom case 10 that are fixedly fitted to each other. The first upper cover 9 and the first bottom case 10 are respectively provided with a first upper cover groove portion 23 and a first bottom case groove portion 24 that penetrate up and down.

The pressing strip 2 is located in front of the first bottom case groove portion 24 and is fixedly provided at the bottom of the first bottom case 10. The light-emitting component 20 is located between the first upper cover 9 and the first bottom case 10 and is laterally fixed on the first upper cover 9 or the first bottom case 10. The light-transmitting component 21 is positioned on the first upper cover groove portion 23 and / or the first bottom case groove portion 24.

[0035] In this embodiment, the first upper cover 9 and the first bottom case 10 are fixed to each other by means of fasteners or buckles, and a first housing cavity is formed therebetween. After the first upper cover 9 and the first bottom case 10 are assembled, a through groove can be formed through the first upper cover groove portion 23 and the first bottom case groove portion 24 that penetrate up and down. The light-emitting component 20 is located in the first housing cavity and is laterally fixed on the first upper cover 9. The pressing strip 2 is a long strip-shaped soft heat-resistant member, and the light-transmitting component 21 is positioned on the first upper cover groove portion 23.

The light-transmitting component 21 is embedded in the first upper cover groove portion 23, and is clamped on the buckle through the positioning portion 25 and covers the first bottom case groove portion 24.

[0037] In this embodiment, the surface of the light-transmitting component 21 is flush with the surface of the first upper cover groove portion 23. The light-transmitting component 21 covers the first bottom case groove portion 24, and at the same time, its bottom is clamped on the buckle through the positioning portion 25, which can prevent foreign objects from entering the through groove and facilitate the user to observe the internal situation of the through groove through the light-transmitting component 21.

[0038] The second housing includes a second upper cover 11 and a second bottom case 12 that are fixedly and cooperatively engaged with each other. A vacuum pumping groove 3 is provided on the surface of the second upper cover 11. A heating element 5 is located on the front side of the vacuum pumping groove 3 and is fixedly provided on the surface of the second upper cover 11.

[0039] In this embodiment, the second upper cover 11 and the second bottom case 12 are fixedly engaged with each other by means of fasteners or snaps, and a second housing cavity is formed therebetween. The vacuum pump 4 is located inside the second housing cavity and is fixed to the second upper cover 11. The heating element 5 is a heating sheet and has the same shape as that of the pressing strip 2.

[0040] The first bottom case 10 is provided with an upper seal 13 corresponding to the first bottom case groove portion 24. The upper seal 13 surrounds the lower opening of the first bottom case groove portion 24. The second upper cover 11 is provided with a lower seal 14 corresponding to the vacuum pumping groove 3.

When the first housing and the second housing are hinged and closed, the upper seal 13 and the lower seal 14 are hermetically engaged with each other to achieve sealed communication between the through groove and the vacuum pumping groove 3.

[0041] When the first housing and the second housing of this embodiment are hinged and closed, by means of the hermetic engagement between the upper seal 13 and the lower seal 14, sealed communication is achieved between the through groove and the vacuum pumping groove 3, thereby avoiding the problem that when the vacuum pump 4 is working, air enters and exits through the through groove and the vacuum pumping groove 3, resulting in unstable air extraction.

[0042] An electronic control board 15 is provided between the second upper cover 11 and the second bottom case 12. The electronic control board 15 is fixedly provided on the second upper cover 11 or the second bottom case 12 and is electrically connected to the vacuum pump 4, the heating element 5, and the lighting element 20.

Correspondingly, a control panel is provided on the first upper cover 9 of the first housing. The electronic control board 15 is electrically connected to the control panel, and the control panel can control the operation of the vacuum pump 4, the heating element 5, and the lighting element 20 through the electronic control board 15.

[0044] A cutter groove 16 is further provided on the surface of the second upper cover 11. The cutter groove 16 is located on the rear side of the vacuum pumping groove 3, and a cutting knife 17 is movably provided thereon.

[0045] When the first housing and the second housing of this embodiment are closed, the upper seal 13 and the lower seal 14 rely on each other for sealing. The vacuum pump 4 operates to evacuate the bag. At the same time, subsequently, the pressure bar 2 and the heating element 5 rely on each other to achieve heat sealing of the bag opening. Finally, the first housing and the second housing are opened, and then the cutting knife 17 is driven to cut the redundant position of the bag, and the entire vacuum sealing operation of the bag can be completed.
