Description

Technical Field

[0001] This utility model relates to the field of household vacuum pump technology, and more specifically to an exhaust and liquid discharge structure for a rechargeable household vacuum pump. Background Technology

[0002] Currently, most rechargeable household vacuum cleaners on the market are mainly used in conjunction with sealed containers such as food storage bags, food containers, and food storage jars with vents to remove air from the containers, thereby extending the shelf life of food, clothing, and other items. However, existing vacuum cleaners still have the following shortcomings in actual use: First, if there is water, oil, or other liquid in the container, the liquid is easily sucked into the machine along with the gas during the vacuuming process. Since most products do not have an independent drainage channel or structure, the liquid can easily remain inside the machine, causing pollution, corrosion, or damage to the circuit system, thus affecting the normal use of the equipment. Second, some vacuum cleaners have complex structures, cumbersome assembly steps, and poor sealing effects, leading to problems such as air leakage and seal failure during long-term use. Therefore, there is an urgent need for a household vacuum cleaner with a simpler structure, stronger sealing performance, and good venting and drainage functions to improve product reliability and user experience. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0026] Please refer to the exhaust and drainage structure of a rechargeable household vacuum pump. Figure 1-5A vacuum pump is used to remove air from a container, which is typically a sealed storage device such as a food storage box, food storage bag, or food storage jar used with a vacuum pump. These containers usually have an exhaust port or valve interface. After food or clothing is placed in the container, air is removed for easy storage. This invention includes a shell 1, an air pump 2, a lower cover 3, and a silicone sealing ring 4. The air pump 2 is located inside the shell 1. The upper end of the lower cover 3 is sealed to the air pump 2, and the lower end of the lower cover 3 is embedded in the silicone sealing ring 4 to form a sealed connection. The shell 1 connects to the lower cover 3 and covers the outer top of the silicone sealing ring 4. The silicone sealing ring 4 is used to seal the exhaust port of the container. In this embodiment, the structure of the silicone sealing ring 4 allows it to mate with the exhaust port on the container to form a seal. The exhaust port of the container is a raised circular structure, and the bottom of the silicone sealing ring 4 can be embedded in the exhaust port of the container. Since the silicone sealing ring 4 is made of silicone, it can be press-fitted to the exhaust port of the container to achieve a sealed connection. After the air pump 2 is started, gas or liquid is extracted through the exhaust port of the container. The outer shell 1 has a first vent 11, the silicone sealing ring 4 has a second vent 41, and the lower cover 3 has a third vent 31. The lower cover 3 is embedded in the silicone sealing ring 4 to align the second vent 41 and the third vent 31. The outer shell 1 is fitted onto the lower cover 3 and covers the outer upper part of the silicone sealing ring 4, aligning the first vent 11 with the second vent 41. The outer shell 1 covering the silicone sealing ring 4 also forms a tight seal. After the outer shell 1, lower cover 3, and silicone sealing ring are assembled, the first vent 11, second vent 41, and third vent 31 can be connected to form an integrated exhaust channel 5. The vacuum pump has fewer components, making its overall structure simple, easy to install, and easy to assemble. The outer shell 1 of this utility model has a square columnar structure, and the lower cover 3 and silicone sealing ring 4 have a corresponding structure to the outer shell 1, facilitating mutual positioning and ensuring that after installation, the first vent 11, second vent 41, and third vent 31 align to form the exhaust channel 5, which allows the vacuum pump to pass through both the inside and outside.

[0027] Furthermore, because the exhaust channel 5 connects the inside and outside of the vacuum pump, the outer shell 1, lower cover 3, and silicone sealing ring 4, after assembly, align the first exhaust port 11, the second exhaust port 41, and the third exhaust port 31 to form a continuous exhaust and liquid discharge channel. Under the suction action, the air pump 2 draws gas or liquid from the container sequentially through the silicone sealing ring 4 and the lower cover 3 into the air pump 2, and then discharges it to the outside through the lower cover 3, the silicone sealing ring 4, and the outer shell 1, preventing liquid from remaining inside the vacuum pump and thus preventing liquid contamination of the interior or malfunction of electrical components. The silicone sealing ring structure can be easily connected to common containers with exhaust ports, such as food storage bags, food containers, and food storage jars, enhancing the product's versatility and applicability.

[0028] Furthermore, the lower cover 3 is provided with an air inlet channel 32 and an air outlet channel 33. The air inlet channel 32 and air outlet channel 33 are cylindrical structures, corresponding to the air inlet and outlet ends of the air pump 2. The air pump 2 is vertically positioned, with its bottom air inlet and outlet ends respectively embedded in the air inlet channel 32 and air outlet channel 33 with an interference fit to achieve a sealed connection. The air inlet channel 32 connects to the hollow structure inside the silicone sealing ring 4. When the vacuum pump connects to the container interface through the silicone sealing ring 4, gas or liquid can smoothly enter the air pump 2. The air outlet channel 33 connects to the second exhaust port 31. That is, after the lower cover 3, silicone sealing ring 4, and outer shell 1 are combined, the air outlet channel 33 connects to the exhaust channel 5, allowing the gas or liquid extracted by the air pump 3 to be discharged to the outside through the exhaust channel 5. Figure 1 , Figure 2 The dashed arrows shown indicate the directions of air intake and exhaust.

[0029] Furthermore, the silicone sealing ring 4 has an annular mounting groove 42 on its inner side, and the bottom of the lower cover 3 has a connecting part 34 that matches the mounting groove 42. The connecting part 34 is a cylindrical structure and is embedded in the mounting groove 42. The connecting part 34 and the mounting groove 42 are interference-fitted to achieve a sealed connection. The lower cover 3 has a first outer edge 35 and a second outer edge 36 extending horizontally outward. The silicone sealing ring 4 has a fixing groove 43 that matches the second outer edge 36, and the second outer edge 36 can be embedded in the fixing groove 43. The bottom of the first outer edge 35 is attached to the upper end face of the silicone sealing ring 4, and the side of the first outer edge 35 is attached to the inner surface of the outer shell 1. The bottom of the outer shell 1 wraps around the outer side of the lower cover 3 and the silicone sealing ring 4. The tight fit of each structure allows the silicone sealing ring 4 to seal the connection between the lower cover 3 and the outer shell 1 and the lower cover 3 at the same time, further improving the sealing performance and the connection stability between the components, ensuring that the vacuum pump can operate normally.

[0030] Furthermore, the first outer edge 35 is provided with four buckles, and the outer shell 1 is provided with a slot that mates with the buckles 37. During assembly, the first exhaust hole 11, the second exhaust hole 41, and the third exhaust hole 31 are aligned to the same side. The lower cover 3 is embedded in the silicone sealing ring 4 for connection. The air pump 2 is embedded in the lower cover 3. Finally, the outer shell 1 is fitted onto the lower cover 3, and the buckles 37 are embedded in the slots to complete the assembly. This utility model has a simple structure, is easy to install, and can effectively improve production efficiency. The outer shell 1 is provided with a circuit board 6 connected to the air pump 2. The circuit board 6 is used to control the operation of the air pump 2 and manage the power supply, button commands, and electronic logic functions such as working status switching of the equipment. The side of the outer shell 1 is provided with control buttons 7 connected to the circuit board 6. The control buttons 7 are used by the user to control the switch or working status of the vacuum pump. Generally, the outer shell 1 is also provided with a lithium battery connected to the circuit board 6 to provide power to the vacuum pump. In addition, the outer shell 1 is also provided with a charging interface connected to the circuit board 6 to charge the lithium battery.
