Description

Technical Field

[0001] The utility model relates to the technical field of vacuum sealing, in particular to a vacuum sealer that can be quickly disassembled and assembled. Background Art

[0002] Vacuum sealers are mainly used for vacuum packaging and storing food, making the shelf life of food longer. The main working principle of household vacuum sealers is as follows: Vacuum extraction: The device is equipped with an in-built vacuum pump. When a bag containing food or other items is placed on the sealing bed and the lid is closed, the vacuum pump starts to work, extracting air from the bag to create a vacuum environment. Heating and sealing: When the preset vacuum degree is reached, the heating wire in the device starts to work, heating and sealing the bag. During the heating process, the bag material melts and adheres, forming a tight seal to ensure that the vacuum state inside the bag is maintained.

[0003] Currently, existing vacuum sealers do not have a detachable structure for the sake of the integrity of the device. However, when household vacuum sealers are used for vacuuming and sealing food, food residues and liquid often enter the vacuum sealer. It is difficult to thoroughly clean the vacuum sealer from the outside, resulting in problems such as bacteria breeding due to residues during long-term use, generating odors, etc., which affect the use effect and experience. Summary of the Utility Model

[0004] To solve the problems existing in the prior art, the utility model provides a vacuum sealer that can be quickly disassembled and assembled.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A vacuum sealer that can be quickly disassembled and assembled includes a base and a top cover rotatably connected to the base. One side of the base that contacts the top cover is connected with a buckle groove protruding member. An assembly and disassembly buckle groove is arranged on the side of the buckle groove protruding member facing the inside of the base. On the side of the top cover that contacts the base, there is a snap-through hole for accommodating the buckle groove protruding member to pass through. At a position corresponding to the snap-through hole inside the top cover, a hook buckle that is engaged and cooperated with the assembly and disassembly buckle groove is installed. The hook buckle is connected with an opening button, and the opening button is arranged on the surface of the top cover.

[0007] Furthermore, on opposite sides of the base, there are rotation assembly and disassembly grooves. The top cover is connected with a rotation assembly and disassembly head that cooperates with the rotation assembly and disassembly grooves. The minimum width of the rotation assembly and disassembly head is smaller than the minimum width of the rotation assembly and disassembly grooves. An assembly and disassembly opening is arranged at the top of the rotation assembly and disassembly grooves.

[0008] Further, the rotary disassembly and assembly groove includes a rotary groove section at the bottom and a disassembly and assembly groove section communicating with the top of the rotary groove section. The rotary groove section is in the shape of a circular groove, and the disassembly and assembly groove section is in the shape of a strip groove. The length of the rotary disassembly and assembly head is less than the diameter of the rotary groove section and greater than the width of the disassembly and assembly groove section, and the width of the rotary disassembly and assembly head is less than the width of the disassembly and assembly groove section.

[0009] Further, a digital display screen is installed on the surface of the top cover.

[0010] Further, a cutting groove is provided on the surface of the top cover, and a cutter mechanism is slidably installed in the cutting groove.

[0011] Further, an upper vacuum pumping groove and a lower vacuum pumping groove communicating with each other are respectively provided inside the top cover and the base, and the upper vacuum pumping groove and the lower vacuum pumping groove communicate with the cutting groove.

[0012] Further, at least two vacuum pumps are installed inside the base, and the vacuum pumps are respectively communicated with the upper vacuum pumping groove and the lower vacuum pumping groove through air pipes.

[0013] Further, a heating element groove is provided on the top cover, and at least two electric heating wires are installed in the heating element groove.

[0014] The beneficial effects of the present utility model are as follows:

[0015] For the vacuum sealer of the present utility model, through the detachable and assembled structures such as the buckle groove protrusions and hook members provided on the base and the top cover, the technical effects of convenient and quick disassembly and quick installation are achieved. When the vacuum sealer needs to be disassembled between the base and the top cover in the closed state, the user presses the opening button on the side of the top cover. At this time, the hook member connected to the opening button inside the top cover is disengaged from the disassembly and assembly buckle groove under the drive of the opening button, and there is no longer a snap connection between the top cover and the base. The top cover can be rotated upward around the base to perform operations such as cleaning and maintenance on the inside of the vacuum sealer, avoiding the difficulty of cleaning and maintaining the inside when there are sundries entering the inside of the vacuum sealer, which affects the normal use of the vacuum sealer.

[0016] The top cover and the base of the vacuum sealer of the present utility model can also be further completely separated. The rotary disassembly and assembly groove provided at the rotation connection between the base and the top cover allows the rotary disassembly and assembly head on the top cover to rotate therein. When the rotary disassembly and assembly head rotates to the side with the smallest width opposite to the outlet of the rotary disassembly and assembly groove, the top cover can be lifted upward, and the rotary disassembly and assembly head is removed from the disassembly opening at the top, that is, the complete separation of the top cover and the base is completed, which is more convenient for separately cleaning and maintaining the top cover and the base.

Detailed implementation manners

[0025] The present utility model will be described in detail below with reference to the drawings and embodiments.

[0026] The present utility model is a vacuum sealer with quick disassembly and assembly, mainly applied to some small - sized vacuum sealers used in household scenarios. For example, after bagging household food, the vacuum sealer is used to pump out the internal air, and then the plastic bag is heated and sealed by a heating element to make the food have a longer shelf life. Specifically, the present utility model can be implemented as follows:

[0027] Please refer to Figure 1 and Figure 2 , Figure 1This is a schematic diagram of the top cover 2 and the base 1 of the vacuum sealer of the present utility model in a normal working state. The top cover 2 is located above the base 1. For more stable operation during disassembly, the top cover 2 and the base 1 are rotatably connected. This rotational connection can be set as some hinge structures such as hinges, hinge supports, etc., or can be set as a structure that can be separated from each other while allowing rotation (the specific structure of this will be described in subsequent embodiments). To facilitate the disassembly of the top cover 2 and the base 1 of the vacuum sealer through simple operations in household use, a snap groove protrusion 3 is connected to the surface of the base 1 that contacts the top cover 2. An assembly and disassembly snap groove 4 is provided on the side of the snap groove protrusion 3 facing the inside of the base 1. The snap groove protrusion 3 can be used to cooperate and engage with corresponding holes or groove components on the top cover 2, and the assembly and disassembly snap groove 4 on it provides a specific position for the mutual engagement of the top cover 2 and the base 1. A snap-through hole 5 for accommodating the snap groove protrusion 3 to pass through is provided on the surface of the top cover 2 that contacts the base 1. A hook part snap 6 that engages with the assembly and disassembly snap groove 4 is installed at a position corresponding to the snap-through hole 5 inside the top cover 2. The bottom end of the hook part snap 6 is provided with a hook-shaped hook part (such as Figure 4 shown) that can hook the assembly and disassembly snap groove 4 after the top cover 2 and the base 1 are closed, so that the two are stably engaged. The hook part snap 6 is connected to an opening button 7 provided on the surface of the top cover 2. After the user presses the opening button 7, the hook part snap 6 inside the top cover 2 connected to the opening button 7 is disengaged from the assembly and disassembly snap groove 4 under the drive of the opening button 7. At this time, there is no longer a snap connection between the top cover 2 and the base 1, and the top cover 2 can be rotated upward around the base 1 to open. The user can perform operations such as cleaning and maintenance on the inside of the vacuum sealer, avoiding the difficulty of cleaning and maintaining the inside when there are sundries entering the inside of the vacuum sealer, which affects the normal use of the vacuum sealer.

[0028] As a preferred embodiment, a button spring mounting rod 16 (such as Figure 5 shown) can be provided at one end of the opening button 7 inside the top cover 2, and a button return spring is sleeved on the button spring mounting rod 16, so that the button can effectively rebound and reset after being pressed to prepare for the next pressing and opening operation. When the top cover 2 and the base 1 are closed, the hook part snap 6 being snapped into the assembly and disassembly snap groove 4 can also be effectively snapped into it with the support of spring force and will not easily come off, further improving the stability of the disassembly and assembly of the vacuum sealer.

[0029] Such as Figure 3As shown, on two opposite sides of the base 1, there are provided rotation disassembly and assembly grooves 9, and on the top cover 2, there is connected a rotation disassembly and assembly head 8 that cooperates with the rotation disassembly and assembly groove 9. The mutual cooperation of the two enables the top cover 2 and the base 1 to be completely separated from each other, thereby realizing targeted cleaning and maintenance of the top cover 2 and the base 1 respectively. Specifically, the minimum width of the rotation disassembly and assembly head 8 is smaller than the minimum width of the rotation disassembly and assembly groove 9. At the top of the rotation disassembly and assembly groove 9, there is a disassembly and assembly opening. The rotation disassembly and assembly groove 9 of this structure allows the rotation disassembly and assembly head 8 that cooperates with it to rotate therein. When the rotation disassembly and assembly head 8 rotates to the side with the minimum width opposite to the disassembly and assembly opening at the top of the rotation disassembly and assembly groove 9, the top cover 2 can be lifted upward. At this time, the rotation disassembly and assembly head 8 moves along the rotation disassembly and assembly groove 9 and is disassembled from the disassembly and assembly opening at its top, that is, the complete separation of the top cover 2 and the base 1 is completed, which is more convenient for separately cleaning and maintaining the top cover 2 and the base 1.

[0030] In order to solve the problem that the rotation disassembly and assembly head 8 may accidentally disengage even when it has not rotated to the specified position or angle, resulting in unexpected situations such as the vacuum machine components falling when the user is unprepared. At the same time, in order to make the disassembly and assembly process of the vacuum sealer more stable, as Figure 6 shown, the present utility model sets the rotation disassembly and assembly groove 9 to include a rotation groove section 91 at the bottom and a disassembly and assembly groove section 92 communicating with the top of the rotation groove section 91. The rotation groove section 91 is in the shape of a circular groove, and the disassembly and assembly groove section 92 is in the shape of a strip groove. The rotation disassembly and assembly groove 9 with this shape setting allows the rotation disassembly and assembly head 8 to rotate in the rotation groove section 91. When disassembling and assembling the top cover 2, the rotation disassembly and assembly head 8 must rotate to an angle where it can move upward or downward along the guiding direction of the disassembly and assembly groove section 92 before it can be disassembled or inserted from the disassembly and assembly opening at the top. In order to improve the stability of this process, in terms of the dimensions of the components of this mechanism, the length of the rotation disassembly and assembly head 8 can be set to be smaller than the diameter of the rotation groove section 91 and larger than the width of the disassembly and assembly groove section 92, so that when it rotates in the rotation groove section 91, it cannot escape from the rotation groove section 91 at other angles. And the width of the rotation disassembly and assembly head 8 is set to be smaller than the width of the disassembly and assembly groove section 92. When the side with the smaller width of the rotation disassembly and assembly head 8 rotates to the guiding direction along the disassembly and assembly groove section 92, it is allowed to be disassembled or inserted along this direction, thereby realizing that the disassembly and assembly process has a guiding function, avoiding the rotation disassembly and assembly head 8 being able to disengage from the disassembly and assembly opening at an inclined angle even when it has not rotated to the specified angle, and also avoiding the rotation disassembly and assembly head 8 being difficult to find the correct installation direction to be installed into the base 1, further improving the convenience and stability of this vacuum sealer.

[0031] As Figure 1As shown in the figure, in order to solve the problem that in the prior art, when a user uses a vacuum sealer, it is not convenient to know the specific completion progress of the vacuum pumping and sealing processes, a digital display screen 11 is installed on the upper surface of the top cover 2 of the present utility model. After the vacuum sealer is turned on and operates, the digital display screen 11 can time the vacuum pumping and sealing times, facilitating the user to observe the completion progress of the vacuum sealing. Specifically, after the bag mouth extends into the internal vacuum pumping slot through the cutting slot 12, the user can operate to start the device. At this time, the vacuum pump starts to work, extracting the air in the bag. The vacuum pumping timing part of the digital display screen 11 starts to display the vacuum pumping time starting from zero. When the vacuum in the bag reaches the set pressure, the device performs the sealing operation, and the heating element starts to heat-seal the bag mouth. At this time, the sealing timing part on the digital display screen 11 starts to display the countdown time according to the set time. When the countdown reaches zero, the device completes the sealing, and the user can then know that the vacuum sealing has been completed.

[0032] As Figure 1 shown in the figure, the present utility model is provided with a cutting slot 12 and a cutter mechanism 13 on the top cover 2, which can cut the bag after vacuum sealing. Under the guiding action of the cutting slot 12, the cut bag mouth is smoother, making the bag after vacuum sealing more convenient to store.

[0033] As Figure 2 shown in the figure, the present utility model is respectively provided with an upper vacuum pumping slot 14 and a lower vacuum pumping slot 15 in the top cover 2 and the base 1. When the top cover 2 and the base 1 are closed, the upper vacuum pumping slot 14 and the lower vacuum pumping slot 15 are connected together, that is, combined into a complete vacuum pumping slot. This structure ensures the compactness of the internal structure of the vacuum sealer while enabling more vacuum pumps to be connected for vacuum pumping work, providing a basis for setting more and better vacuum pumps for the vacuum sealer and avoiding the problem of limited vacuum pumping effect. As a preferred implementation manner, the vacuum sealer of the present utility model is internally provided with a double vacuum pump, which is connected to the vacuum pumping slot through structures such as air pipes to improve the vacuum pumping effect. The number of vacuum pumps can also be specifically set according to the device size and functional requirements, such as setting three, four, etc.

[0034] As Figure 2As shown, in order to improve the sealing effect of the packaging bag and make the sealing faster and more uniform, the present utility model is provided with at least two electric heating wires in the heating element groove 10, so that the heating positions are heated more quickly and evenly, avoiding the problem of excessive or lower local temperature. Preferably, two electric heating wires are provided and arranged side by side on the plane in the heating element groove 10, which can preferably meet the working requirements of the household vacuum sealer. In order to further ensure the sealing effect, three electric heating wires can also be provided. The specific quantity and arrangement can be selected according to the size and functional requirements of the vacuum sealer.

[0035] The above embodiments only express the specific implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
