Technical Field

[0001] This application relates to the field of sealing caps, and more particularly to a vacuum-sealed cap. Background Technology

[0002] As people's living standards improve, they are paying more and more attention to the preservation and storage of food, especially the storage of daily necessities such as pet food and grains. These items are prone to moisture or oxidation, which can lead to a decline in quality.

[0003] Currently, most common storage containers on the market use simple sealed lids, which can prevent outside air from entering to some extent, but the stored items may still become damp or oxidized. Utility Model Content

[0004] To reduce the probability of items getting damp or oxidized, this application provides a vacuum-sealed cover.

[0005] The vacuum-electrifiable cover provided in this application adopts the following technical solution:

[0006] A vacuum-ejectable cover includes a cover body, a miniature electric vacuum pump, an inlet pipe, and an outlet pipe. One end of the cover body has a mounting groove with an inlet at the bottom. The other end of the cover body has an outlet. The cover body has a receiving cavity between the inlet and the outlet. The pump body of the miniature electric vacuum pump is fixedly connected to the inner wall of the receiving cavity. One end of the inlet pipe is connected to the suction end of the miniature electric vacuum pump, and the other end of the inlet pipe is coaxially fixedly connected to the inner wall of the inlet. One end of the outlet pipe is connected to the outlet end of the miniature electric vacuum pump, and the other end of the outlet pipe is coaxially fixedly connected to the inner wall of the outlet.

[0007] By adopting the above technical solution, the cover is installed on the bag to be vacuumed, and the micro electric vacuum pump is started to draw the air in the bag into the air inlet and then discharge it from the air outlet, so that the bag achieves a vacuum, realizing efficient and stable vacuuming and reducing the probability of items getting damp or oxidized.

[0008] Preferably, it also includes a miniature lithium-ion battery and a control circuit board, both of which are fixedly connected to the inner wall of the receiving cavity, and both the miniature lithium-ion battery and the miniature electric vacuum pump are electrically connected to the control circuit board.

[0009] By adopting the above technical solution, the micro lithium-ion battery supplies power to the micro electric vacuum pump through the control circuit board, and the control circuit board controls the start and stop of the micro electric vacuum pump, which is convenient to use.

[0010] Preferably, it also includes a protrusion, which is fixedly connected to one end of the cover away from the mounting groove, and the air outlet is located on the outer periphery of the protrusion.

[0011] By adopting the above technical solution, the protrusion is easier for users to hold, thus improving the installation efficiency of the cover.

[0012] Preferably, a vacuum button is fixedly connected to the end of the protrusion facing away from the cover, and the vacuum button is electrically connected to the control circuit board.

[0013] By adopting the above technical solution, it is convenient for users to control the start and stop of the micro electric vacuum pump. Pressing the vacuum button will cause the control circuit board to control the micro lithium-ion battery to power the micro electric vacuum pump, and the micro electric vacuum pump will start working.

[0014] Preferably, a power indicator light is fixedly connected to the end of the protrusion facing away from the cover, and the power indicator light is electrically connected to the control circuit board.

[0015] By adopting the above technical solution, the power indicator light reminds the user whether the power is on, making it easier for the user to judge the status of the vacuum cover.

[0016] Preferably, a charging interface is fixedly connected to the end of the protrusion facing away from the cover, and the charging interface is electrically connected to the control circuit board.

[0017] By adopting the above technical solution, it is easy to charge the micro lithium-ion battery, enabling the vacuum cover to be used continuously.

[0018] Preferably, it also includes a pressure sensor, which is fixedly connected to the inner wall of the air intake pipe and electrically connected to the control circuit board.

[0019] By adopting the above technical solution, when the miniature electric vacuum pump draws the bag into a vacuum, the pressure sensor senses that the bag is in a vacuum and transmits the vacuum signal to the control circuit board. The control circuit board then controls the miniature electric vacuum pump to shut down, and the vacuuming stops.

[0020] Preferably, it also includes a sliding plate, and the end of the cover opposite to the mounting groove is provided with a fixing groove. The air outlet is located at the bottom of the fixing groove, and the sliding plate is slidably embedded in the fixing groove. The sliding plate is used to cover the air outlet.

[0021] By adopting the above technical solution, when vacuuming is required, the sliding plate slides to open the air outlet, which facilitates the exhaust of gas. When vacuuming is completed, the sliding plate slides to close the air outlet, reducing the backflow of external gas into the bag.

[0022] Preferably, the wall of the fixing groove is provided with an anti-detachment groove, and the outer wall of the sliding plate is fixedly connected with an anti-detachment plate, which is slidably connected to the wall of the anti-detachment groove.

[0023] By adopting the above technical solution, the anti-detachment plate always slides within the anti-detachment groove, preventing the sliding plate from falling out of the fixed groove.

[0024] Preferably, the wall of the mounting groove is fixedly connected with an internal thread.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Install the cover on the bag to be vacuumed. The mini electric vacuum pump starts to draw the air in the bag into the air inlet and then discharge it from the air outlet, so that the bag is vacuumed. This achieves efficient and stable vacuuming and reduces the probability of items getting damp or oxidized.

[0028] 2. The micro electric vacuum pump is easy for users to control to start and stop. Pressing the vacuum button activates the control circuit board, which controls the micro lithium-ion battery to power the micro electric vacuum pump, and the micro electric vacuum pump starts working.

[0029] 3. When vacuuming is required, the sliding plate slides to open the vent, facilitating air release. When vacuuming is complete, the sliding plate slides to close the vent, reducing the backflow of external gas into the bag. Attached Figure Description
