Technical Field

[0001] This utility model relates to the field of food storage container technology, specifically a coffee sealing jar with weighing function. Background Technology

[0002] A coffee airtight container is a container specifically designed to store coffee beans or coffee powder and to preserve their freshness, flavor, and quality to the maximum extent through physical or chemical means. Its core function is to slow down the oxidation and deterioration process of coffee by isolating it from external factors such as oxygen, light, moisture, and odors. It may also integrate intelligent functions such as weighing and environmental monitoring.

[0003] After coffee beans are roasted, their internal structure becomes loose and porous, making them prone to oxidation with oxygen in the air, which leads to a gradual loss of flavor. Therefore, using airtight containers for storage and preservation is an important way to delay the loss of coffee bean flavor. Traditional coffee airtight containers usually have a vacuum component installed on the lid. The vacuum component creates a vacuum in the container, and the lid is sealed with a silicone sealing ring to preserve the coffee beans.

[0004] However, when taking coffee beans, users need to control the amount precisely. The traditional way is to use an additional electronic scale to weigh them, which not only increases the operation steps and equipment costs, but also brings inconvenience to use. Although traditional coffee sealing jars can delay the loss of coffee bean flavor by vacuuming, they cannot meet the user's need to complete weighing and sealing in one stop due to the lack of weighing function. Utility Model Content

[0005] The purpose of this invention is to provide a coffee sealing container with a weighing function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coffee sealing jar with weighing function, comprising a sealing jar body and a placement base, wherein a placement groove is formed on the upper surface of the placement base, a control chamber is fixedly connected to the bottom of the inner cavity of the sealing jar body, a weighing module is fixedly connected to the top of the control chamber, a glass jar is placed on the upper surface of the weighing module, a jar lid is inserted into the top of the sealing jar body, the sealing jar body is placed in the placement groove, an installation groove is formed on the upper surface of the placement base, and a fixing component is fixedly connected to the inner wall of the installation groove.

[0015] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Please see Figures 1-5 The present invention provides the following two preferred embodiments: Example 1: A coffee sealing jar with weighing function includes a sealing jar body 1, an LCD display screen embedded on the outer surface of the sealing jar body 1, and a placement base 3. The upper surface of the placement base 3 has a placement groove for placing the sealing jar body 1, ensuring stable placement. A control chamber 7 is fixedly connected to the bottom of the inner cavity of the sealing jar body 1. A battery pack and controller are installed in the control chamber 7. The battery pack, controller, LCD display screen, and vacuum assembly are electrically connected. A weighing module 8 is fixedly connected to the top of the control chamber 7. The battery pack provides power to the entire device, and the controller coordinates and controls the operation of various components, such as controlling the weighing operation of the weighing module 8, the vacuuming operation of the vacuum assembly, and the information display on the LCD display screen. A glass jar 9 is placed on the upper surface of the weighing module 8 for directly storing coffee beans. The glass jar 9 is transparent, allowing users to easily observe the storage status of the coffee beans. The weighing module 8 can accurately measure the weight of the coffee beans inside the glass jar 9 and transmit the weight information to the controller. A can lid 2 is inserted into the top of the main body 1, and is vacuum sealed with the main body 1 through a silicone sealing ring. The vacuum component on the can lid 2 can extract the air from the main body 1 after the can lid 2 is closed, creating a vacuum environment. The vacuum component is mainly composed of a top cover, a vacuum pump, and a one-way valve, and is used to extract the air from the main body 1 to keep the glass jar 9 in a vacuum state. The main body 1 is placed in the placement slot. The upper surface of the placement seat 3 has an installation slot. The inner wall of the installation slot is fixedly connected to a fixing component 6 to fix the main body 1 and prevent it from shaking during placement or use, thereby improving the accuracy of weighing. The bottom of the placement seat 3 is fixedly connected to an anti-slip pad 4 to increase the friction between the placement seat 3 and the contact surface and prevent slippage. The upper surface of the placement seat 3 is fixedly connected to a maintenance cover 5 by screws, which is convenient to open the maintenance cover 5 to repair or inspect the inside of the placement seat 3 when needed. The upper surface of the maintenance cover 5 has a through slot to facilitate the pulling of the connecting rod 66.

[0017] In actual use, after closing the sealed container body 1 and the lid 2, the vacuum assembly installed on the lid 2 is activated. The vacuum pump in the vacuum assembly starts working, drawing out the air inside the sealed container body 1 through the one-way valve, keeping the glass jar 9 in a vacuum state. This slows down the oxidation and deterioration process of the coffee beans, maintaining their freshness and flavor. When coffee beans need to be taken out, the lid 2 is opened, and the weighing module 8 automatically starts working, measuring the weight of the coffee beans in the glass jar 9. The weighing module 8 transmits the weight information to the controller in the control chamber 7. The controller then displays the information on the LCD screen embedded on the outer surface of the sealed container body 1, showing the weight of the beans taken out and the weight of the remaining coffee beans in the container. It also displays the total amount of beans in the sealed container and the current amount of beans taken out, allowing users to accurately control the amount of coffee beans used.

[0018] Example 2: The fixing component 6 includes a first mounting plate 61 and a second mounting plate 610 fixedly connected to the inner wall of the mounting groove. These fixedly connected components support and fix the mounting shell 62. The mounting shell 62 is fixedly connected between the first mounting plate 61 and the second mounting plate 610. A sliding groove 64 is formed through the outer surface of the mounting shell 62 to provide a track for the sliding of the connecting rod 66. A movable rod 68 is slidably connected to the inner wall of the second mounting plate 610, and can slide on the inner wall of the second mounting plate 610 under the action of a movable block 65. A through groove is formed through the inner wall of the mounting groove to facilitate the sliding of the movable rod 68. An arc-shaped fixing plate 63 is fixedly connected to the end of the movable rod 68 away from the second mounting plate 610, and is connected to the movable block 65 through the movable rod 68. This plate abuts against the outer surface of the sealing tank body 1 to fix the sealing tank body 1. A movable block 65 is slidably connected to the inner wall of the mounting shell 62. The side of the movable block 65 closest to the second mounting plate 610 is connected to the movable rod 68. 8. One end of the movable block 65 away from the arc-shaped fixed plate 63 is fixedly connected. A first abutment groove is provided on the side of the movable block 65 away from the movable rod 68 for inserting a spring 69. The inner wall of the first abutment groove is fitted with a spring 69 to provide restoring force to the movable block 65, allowing the arc-shaped fixed plate 63 to tightly abut against the outer surface of the sealed container body 1. A second abutment groove is provided on the side of the mounting plate 61 near the movable block 65. The end of the spring 69 away from the first abutment groove is inserted into the inner wall of the second abutment groove. The outer surface of the movable block 65... A connecting rod 66 is fixedly connected to the surface and can slide in the sliding groove 64 under the drive of the movable block 65. The outer wall of the connecting rod 66 is slidably connected to the inner wall of the sliding groove 64. A pull rod 67 is fixedly connected to the end of the connecting rod 66 away from the movable block 65. By pulling the pull rod 67, the connecting rod 66 and the movable block 65 can be moved, thereby realizing the movement of the arc-shaped fixed plate 63. Multiple protrusions are fixedly connected to the outer wall of the pull rod 67. The protrusions are distributed in a ring array for easy gripping and pulling by the user.

[0019] In actual use, firstly, the operator holds the pull rod 67 and pulls it outward. The pull rod 67, through the connecting rod 66, drives the movable block 65 to slide against the inner wall of the mounting shell 62 towards the mounting plate 61. The movement of the movable block 65 drives the movable rod 68 to slide against the inner wall of the mounting shell 62, thereby pulling the arc-shaped fixing plate 63 towards the mounting plate 610. At the same time, the spring 69 is compressed. At this time, the sealing can body 1 is placed in the placement slot opened on the placement seat 3, ensuring that the sealing can body 1 is placed stably. The pull rod 67 is released, and the spring 69, under the action of the restoring force, pushes the movable block 65 to slide against the inner wall of the mounting shell 62 towards the mounting plate 610. The movement of the movable block 65 pushes the movable rod 68 and the arc-shaped fixing plate 63 towards the sealing can body 1, so that the arc-shaped fixing plate 63 is tightly pressed against the outer surface of the sealing can body 1, thereby fixing the sealing can body 1 and ensuring that it will not shake during placement and use, thus improving the accuracy of weighing.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
