Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and in particular to a novel vacuum compression bag. Background Technology

[0002] With the improvement of people's living standards and the increasing scarcity of living space, the storage and management of items such as clothing and bedding has become an important issue. Vacuum compression bags are widely used due to their advantages of significantly compressing the volume of items and saving storage space. Traditional vacuum compression bags mainly consist of a flexible bag body and an openable and closable sealing opening at the bag mouth. The bag body usually has one or more vacuum ports that connect to the outside world, which are used in conjunction with vacuum pumps to remove air from the bag.

[0003] However, existing vacuum compression bags reveal a major technical problem during use. Most vacuum compression bags on the market lack standardized interfaces and use generic interfaces, requiring users to separately purchase a manual pump or use a household vacuum cleaner for vacuuming. This separate design leads to two core drawbacks: firstly, users need to carry or find additional vacuuming tools, making operation cumbersome and inconvenient; secondly, because the interfaces of vacuum cleaners or manual pumps are difficult to precisely and stably match the compression bag interfaces, **the connections are prone to loosening and poor sealing**, leading to frequent air leaks, resulting in low vacuuming efficiency and difficulty in achieving the desired vacuum effect. Furthermore, the inconsistent power or efficiency of generic vacuuming tools also fails to guarantee consistent vacuuming results.

[0004] Therefore, this utility model proposes a novel vacuum compression bag, which aims to solve the problems of mismatched interfaces, unstable connections, and poor sealing of vacuum compression bag pumping tools in the prior art, thereby achieving the purpose of quickly, efficiently, and stably vacuum compressing and storing items. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a novel vacuum compression bag, which aims to improve the problems of mismatched interfaces, poor sealing, and inconvenient operation of vacuum compression bag extraction tools in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel vacuum compression bag, comprising: a vacuum compression bag, a vacuum interface assembly, and a portable vacuum pump.

[0007] The vacuum interface assembly includes an interface base, which is integrally formed on the surface of the vacuum compression bag by hot pressing, and the interface base is in communication with the internal space of the vacuum compression bag.

[0008] The portable vacuum pump is the core component for achieving rapid air extraction. The portable vacuum pump includes a protective shell, with a positioning post at the bottom of the protective shell, and a positioning hole on the interface base that matches the shape and size of the positioning post.

[0009] The positioning post and the positioning hole are combined via a detachable plug-in connection, which enables quick alignment and stable sealing between the portable vacuum pump and the vacuum interface assembly. A drive motor is snap-fitted into the interior of the protective shell. The output end of the drive motor is fixedly connected to the upper end of the drive mechanism, while the lower end of the drive mechanism is fixedly connected to an extraction fan located at the bottom of the protective shell. This extraction fan is used to extract air from the vacuum compression bag.

[0010] Preferably, the vacuum compression bag has a reusable sealing opening at the bag opening away from the vacuum interface assembly, the sealing opening being used to initially seal the vacuum compression bag before evacuation.

[0011] Preferably, an interface filter is fixed inside the interface base on the airflow channel between the exhaust fan and the internal space of the vacuum compression bag. The interface filter is used to prevent debris inside the vacuum compression bag from entering the portable vacuum pump.

[0012] Preferably, the interface base is further provided with a one-way valve structure, which is used to automatically close the air passage after the portable vacuum pump is removed to prevent external air from flowing back.

[0013] Preferably, an operation button is installed on the top outer surface of the protective shell. The operation button is electrically connected to the drive motor and is used to control the start and stop of the drive motor.

[0014] Preferably, the protective shell has heat dissipation holes on its side wall, which are used to dissipate the heat generated by the drive motor to the outside in a timely manner.

[0015] Preferably, an annular fan baffle is coaxially fixed to the outer periphery of the exhaust fan, and the fan baffle provides physical isolation and protection for the high-speed rotating exhaust fan.

[0016] Preferably, a rechargeable battery for powering the drive motor is also fixed inside the protective shell, and the rechargeable battery is electrically connected to the operation button and the drive motor in sequence through internal wires.

[0017] Preferably, the outer wall of the protective shell is provided with a Universal Serial Bus Type-C charging interface, which is electrically connected to the charging management circuit of the rechargeable battery for charging the rechargeable battery.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model solves the problems of difficult docking, unstable connection, and poor sealing between the vacuum pump and the compression bag interface in the prior art by setting a positioning post at the bottom of the portable vacuum pump and setting a positioning hole on the vacuum interface assembly, and by using the plug-in mating structure of the positioning post and the positioning hole. It realizes quick alignment and stable sealing connection between the vacuum pump and the compression bag, and improves the vacuuming efficiency and operation convenience.

[0020] 2. This utility model integrates core components such as the drive motor, drive mechanism, and vacuum fan inside the protective shell of a portable vacuum pump, and clearly defines the transmission relationship between the drive motor and the vacuum fan through the drive mechanism.

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-4 The present invention provides an embodiment of a novel vacuum compression bag, comprising a vacuum compression bag 1, a vacuum interface assembly 2 fixedly connected to the vacuum compression bag 1, and a portable vacuum pump 3 used in conjunction with the vacuum interface assembly 2.

[0029] The vacuum interface assembly 2 includes an interface base 201, which is integrally formed on the surface of the vacuum compression bag 1 by hot pressing and is connected to the internal space of the vacuum compression bag 1.

[0030] The portable vacuum pump 3 is the core component for achieving rapid air extraction. The portable vacuum pump 3 includes a protective shell 301. The bottom of the protective shell 301 is provided with a positioning post 306. The interface base 201 is provided with a positioning hole 202 that matches the shape and size of the positioning post 306. In use, the positioning post 306 can be detachably inserted into the positioning hole 202. This precise insertion structure enables rapid alignment and stable sealing connection between the portable vacuum pump 3 and the vacuum interface assembly 2.

[0031] The protective shell 301 has a complete drive and suction mechanism built inside. Specifically, a drive motor 304 is snapped and fixed inside the protective shell 301. The output end of the drive motor 304 extends vertically downward and is fixedly connected to the upper end of the drive mechanism 308. The lower end of the drive mechanism 308 is fixedly connected to the suction fan 307, thus forming a stable power transmission path from the drive motor 304 to the drive mechanism 308 and then to the suction fan 307. The suction fan 307 is located at the bottom of the protective shell 301, and the suction direction of the suction fan 307 is towards the side where the positioning post 306 is located, so as to extract the air from the vacuum compression bag 1.

[0032] The vacuum compression bag 1 has a sealing port 101 that can be repeatedly opened and closed at the bag opening away from the vacuum interface assembly 2. The sealing port 101 is used to initially seal the vacuum compression bag 1 before evacuation.

[0033] To ensure cleanliness during the extraction process and maintain vacuum after extraction, an interface filter 203 is fixed inside the interface base 201 of the vacuum interface assembly 2, on the airflow channel between the extraction fan 307 and the internal space of the vacuum compression bag 1. The interface filter 203 is used to prevent debris in the vacuum compression bag 1 from entering the portable vacuum pump 3. At the same time, a one-way valve structure is also fixed inside the vacuum interface assembly 2. The one-way valve structure is used to automatically close the air passage after the portable vacuum pump 3 is removed to prevent external air from flowing back.

[0034] To improve the ease of operation and stability of the portable vacuum pump 3, an operation button 303 is installed on the top outer surface of the protective shell 301. The operation button 303 is electrically connected to the internal drive motor 304 and is used to control the start and stop of the drive motor 304. At least one heat dissipation hole 302 is provided on the side wall of the protective shell 301. The heat dissipation hole 302 is used to dissipate the heat generated by the drive motor 304 during operation to the outside in a timely manner. In addition, an annular fan baffle 305 is coaxially fixed on the outer periphery of the exhaust fan 307. The fan baffle 305 provides physical isolation protection for the high-speed rotating exhaust fan 307.

[0035] As a preferred embodiment, to improve the portability and independent operation capability of the portable vacuum pump 3, a rechargeable battery for powering the drive motor 304 is also fixed inside the protective shell 301. The rechargeable battery is electrically connected to the operation button 303 and the drive motor 304 in sequence through internal wires, forming a power supply control circuit. In addition, to facilitate charging of the rechargeable battery, a Universal Serial Bus Type-C charging interface is provided on the outer wall of the protective shell 301. This Universal Serial Bus Type-C charging interface is electrically connected to the charging management circuit of the rechargeable battery.

[0036] Working principle: When using this new type of vacuum compression bag 1 for storage, the staff first put the clothes or quilts to be stored into the internal space of the vacuum compression bag 1, and manually press the sealing opening 101 at the bag opening to ensure that the vacuum compression bag 1 is in a preliminary sealed state.

[0037] Subsequently, the staff held the portable vacuum pump 3 and aligned the positioning post 306 at the bottom of the protective shell 301 with the positioning hole 202 on the vacuum interface assembly 2 and inserted it downwards. Through the tight insertion and cooperation between the positioning post 306 and the positioning hole 202, the portable vacuum pump 3 was securely installed on the interface base 201, avoiding the problems of poor interface compatibility and air leakage in the traditional air extraction method. This structure ensures the airtightness of the air extraction channel.

[0038] After installation, press the operation button 303 on the top of the protective case 301. The internal rechargeable battery starts to power the drive motor 304. The drive motor 304 then drives the bottom exhaust fan 307 to rotate at high speed through the drive mechanism 308. The operation of the exhaust fan 307 creates a negative pressure area at the interface, generating a strong pressure difference between the inside of the vacuum compression bag 1 and the outside.

[0039] Under the action of pressure difference, the air in the vacuum compression bag 1 is forcibly extracted. The airflow passes through the interface base 201 and the interface filter 203 in sequence. During this process, the interface filter 203 effectively blocks clothing fibers from entering the pump body, preventing impurities from damaging the drive mechanism 308 and the drive motor 304. The filtered air enters the portable vacuum pump 3 and is discharged. During this period, the heat dissipation holes 302 on the side wall of the protective shell 301 continuously discharge the heat generated by the drive motor 304 to maintain the stable operation of the equipment.

[0040] After the air in the vacuum compression bag 1 is completely evacuated and the volume is compressed to the ideal state, press the operation button 303 again to stop the drive motor 304 from running, and then pull the portable vacuum pump 3 upward. At this time, the one-way valve structure inside the vacuum interface assembly 2 will immediately close automatically under the action of the internal and external pressure difference to prevent external air from flowing back. Thus, together with the sealing port 101, it will maintain the vacuum storage state in the vacuum compression bag 1 for a long time.
