Description

Technical Field

[0001] This utility model belongs to the technical field of vacuum pumping devices, and in particular relates to a threaded automatic vacuum pumping device. Background Technology

[0002] To prevent food items such as tea, coffee, and medicinal herbs from becoming damp and spoiling due to prolonged storage, current technology uses vacuum containers for preservation.

[0003] A vacuum container is specifically designed by adding a vacuum device to the top of the container. The vacuum device contains a vacuum pump, solenoid valve, control board, and sealing components. The vacuum pump extracts the air from the container to create a vacuum environment, allowing the food stored in the container to be stored for a longer period of time. For example, the application number CN202420805759.6 filed by the applicant is entitled "An Automatic Vacuuming Device for Vacuuming Containers". It includes an upper cover and a lower cover, which are connected by a buckle, a slot, a positioning hole and a positioning post. In practical applications, it has the following disadvantages: (1) The sealing performance needs to be improved: Since the sealing ring is filled at the lower edge of the lower cover and the sealing ring contacts the top of the connecting ring, the relative contact surface is small. Under the small contact surface, if misalignment occurs, gaps are easily generated, which leads to air leakage and affects the sealing performance; (2) When the lower cover and the connecting ring support are not vacuumed, they are in contact rather than connected, which makes the lower cover easy to be lost or mixed with other containers, resulting in mismatch; Therefore, in view of the above problems, this technical solution provides a threaded automatic vacuuming device. Utility Model Content

[0004] This utility model provides a threaded automatic vacuum device. A sealing ring is installed inside a sealing ring located at the lower part of the lower cover. The first connecting thread on the inner circumference of the scraper ring at the lower part of the upper cover and the second connecting thread on the outer circumference of the connecting ring are threadedly engaged. This enables the upper cover to be stably installed on the upper part of the container while simultaneously providing stable pressure on the sealing ring, further improving the sealing performance. Because the first connecting thread and the second connecting thread have a matching connection relationship, it can avoid problems such as the loss of the cover and incompatibility with other containers. In summary, this invention solves the problems in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model provides a threaded automatic vacuuming device, which includes an upper cover, a lower cover, and a connecting ring installed at the top opening of a container. The upper cover and the lower cover are connected vertically, and a sealing ring mounting groove is formed at the lower part of the lower cover.

[0007] A sealing ring is installed inside the sealing ring;

[0008] The upper cover and the connecting ring are connected by a threaded structure. The threaded structure includes a first connecting thread located on the inner circumference of the scraper ring at the lower part of the upper cover and a second connecting thread located on the outer circumference of the connecting ring. The first connecting thread and the second connecting thread are threadedly engaged.

[0009] After the upper cover is threadedly connected to the connecting ring, the sealing ring is pressed and connected to the upper part of the threaded connection position, and is sealed and wrapped by the sealing ring mounting groove, the scraper ring at the bottom of the upper cover, and the upper end face of the connecting ring.

[0010] Furthermore, the sealing ring mounting groove is provided with a positioning blind hole, and the sealing ring is provided with a plug-in post corresponding to the positioning blind hole.

[0011] Furthermore, the sealing ring is bonded to the inner wall of the sealing ring mounting groove by adhesive.

[0012] The present invention has the following advantages over the prior art:

[0013] (1) In this technical solution, a sealing ring is installed in the sealing ring at the lower part of the lower cover. The first connecting thread on the inner circumference of the scraper ring at the lower part of the upper cover and the second connecting thread on the outer circumference of the connecting ring are threaded together, which can realize the stable installation of the upper cover on the upper part of the container, while the sealing ring is stably pressed, further improving the sealing performance.

[0014] (2) Due to the threaded connection structure, that is, the first connecting thread and the second connecting thread have a matching connection relationship, the problem of loss of the cover and misuse with other containers can be avoided.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "lower part", "inner", "peripheral side", "upper part", "upper end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0032] Please see Figure 1-6 As shown, the present invention provides a threaded automatic vacuum device, which includes an upper cover 1, a lower cover 2, and a connecting ring 4 installed at the top opening of a container 6. The upper cover 1 and the lower cover 2 are connected vertically, and a sealing ring mounting groove 24 is formed at the lower part of the lower cover 2.

[0033] like Figure 3 As shown, a sealing ring 5 is installed in the sealing ring mounting groove 24;

[0034] like Figure 5-6 As shown, the upper cover 1 and the connecting ring 4 are connected by a threaded structure. The threaded structure includes a first connecting thread 11 located on the inner circumference of the scraper ring at the lower part of the upper cover 1 and a second connecting thread 41 located on the outer circumference of the connecting ring 4. The first connecting thread 11 and the second connecting thread 41 are threadedly engaged. By rotating the upper cover 1, the first connecting thread 11 of the upper cover 1 and the second connecting thread 41 on the circumference of the connecting ring 4 can be rotatably connected. The rotating threaded structure not only achieves the threaded connection between the two and improves the sealing performance, but also allows the sealing ring 5 to be tightly pressed between the sealing ring mounting groove 24 and the connecting ring 4, further improving the sealing performance. At the same time, since the first connecting thread 11 and the second connecting thread 41 are threadedly matched, the problems of cover loss, misuse with other containers, and incompatibility can be avoided.

[0035] After the upper cover 1 is threadedly connected to the connecting ring 4, the sealing ring 5 is pressed and connected to the upper part of the threaded connection position, and is sealed and wrapped by the sealing ring mounting groove 24, the lower scraping ring of the upper cover 1 and the upper end face of the connecting ring 4.

[0036] The sealing ring mounting groove 24 is provided with a positioning blind hole 211, and the upper sealing ring is provided with a plug post 51 corresponding to the positioning blind hole 211; the sealing ring 5 is made of rubber.

[0037] In this specific embodiment, the upper cover 1 and the lower cover 2 are fixedly connected by a bottom-mounted screw. The specific structure is as follows: a positioning post 21 is provided on the upper surface of the lower cover 2, a positioning blind hole 211 coaxial with the positioning post 21 is provided in the sealing ring mounting groove 24, a screw hole 23 coaxial with the positioning blind hole 211 is provided in the positioning blind hole 211, and a positioning threaded hole 12 corresponding to the positioning post 21 is provided at the inner bottom of the upper cover 1.

[0038] The screw hole 23 and the positioning threaded hole 12 are connected by screws, so that the lower cover 2 and the upper cover 1 are connected as one unit; the diameter of the positioning threaded hole 12 is smaller than the diameter of the positioning blind hole 211. The locking screw passes through the positioning blind hole 211 and is screwed into the screw hole 23 to lock and engage with the upper positioning threaded hole 12, thereby achieving a locking connection between the upper cover 1 and the lower cover 2; in this specific embodiment, the corresponding positioning blind hole 211, screw hole 23 and positioning threaded hole 12 are all in three sets, and the arc between two adjacent sets is 120°;

[0039] The lower cover 2 has a control plate 3 on its inner surface; the control plate 3 has a raised vacuum switch button 31 on its surface, which is located directly below the top plate of the upper cover 1.

[0040] The top plate is made of silicone, rubber, or acrylic plastic. When the top plate is pressed down, the vacuum switch button 31 can be pressed directly, and after pressing, it can disengage and return to its original state.

[0041] The lower cover 2 has a buckle 22 inside, and the control board 3 is snapped onto the buckle 22. At the bottom of the control board 3 are a vacuum pump, a solenoid valve, a battery, and gas pipelines. The vacuum pump, solenoid valve, and battery are all miniature in structure and are consistent with the components and functions used in the background technology. The specific models can be purchased from the market. The specific connection relationship is as follows: the USB interface, LED light group, battery, pressure sensor, vacuum pump, solenoid valve, gas check valve, and vacuum switch button are electrically connected to the microcontroller. The specific principle is not the protection point of this technical solution and will not be described in detail. Specific Implementation Example 2:

[0043] like Figure 7-10 As shown, the difference between this specific embodiment and specific embodiment 1 is that:

[0044] The sealing ring 5 is bonded to the inner wall of the sealing ring mounting groove 24 by adhesive.

[0045] The top of the upper shell cover 1 is provided with a sealing plate, the center of the sealing plate has a through hole 14, the outer periphery of the sealing plate is provided with a limiting groove 13, and the surface of the sealing plate is provided with a positioning hole 15; a cover 7 is fitted inside the limiting groove 13; the vacuum switch button 31 is located directly below the through hole 14.

[0046] The upper cover 1 and the lower cover 2 are connected to the positioning post 21 by screws through the positioning hole 15 to achieve locking and fixation; the cover 7 is made of light-transmitting material, such as silicone, rubber, thin acrylic plastic or plastic; since there is a certain distance between the cover 7 and the limiting groove 13, when the cover 7 is pressed down, the bottom of the cover 7 can contact the vacuum switch button 31, and the cover 7 can bounce up and return to its original state after being pressed; in order to ensure the sealing between the cover 7 and the limiting groove 13, a sealing ring or sealant can be applied at the contact position between the two.
