[0047] Embodiment 1

[0048] Refer to Figures 1 to 3, the first embodiment of the present utility model proposes a pure air filtration device, which includes a box body 100 for containing liquid. The box body 100 has an air inlet 101 and an air outlet 102; an air pump 200 is arranged on the box body 100, one end of the air pump 200 leads to the air inlet 101, and the other end is communicated with the outside. The air pump 200 is used to extract gas and introduce it into the liquid; a placement box 300 is arranged on the box body 100, the placement box 300 is located above the box body 100, and the air pump 200 is arranged in the placement box 300; one end of the first extension pipe 400 is arranged at the air outlet end of the air pump 200, and the other end is below the liquid level of the liquid in the box body 100.

[0049] In this embodiment, the box body 100 serves as the basis of the entire device. The box body 100 is used to contain the liquid for purification, and the liquid can be water or other special purification liquids. The box body 100 is provided with an air inlet 101 and an air outlet 102, which are respectively used to introduce the air to be purified and discharge the purified air. The air pump 200 is installed in the placement box 300. The function of the air pump 200 is to generate negative pressure, suck the outside air in and introduce it into the interior of the box body 100 through the air inlet 101. One end of the air pump 200 communicates with the outside, and the other end is connected to the air inlet 101 to ensure the continuity of air flow.

[0050] The placement box 300 is located above the box body 100, which is not only convenient for installing and maintaining the air pump 200, but also can prevent the air pump 200 from directly contacting the purification liquid and protect the equipment. One end of the first extension pipe 400 is connected to the air outlet end of the air pump 200, and the other end extends into the liquid in the box body 100 and is lower than the liquid level. When the air pump 200 works, the extracted air is forced into the liquid through this pipe, promoting the full contact between the air and the liquid, realizing the dissolution, sedimentation of pollutants in the gas or being absorbed by the components in the liquid, and achieving the purpose of removing odors. During the use of this device, only the purification liquid needs to be replaced regularly, and the maintenance cost is low.

[0051] Furthermore, the box body 100 also has a slot 103, and the placement box 300 has a plug-in part 301. The plug-in part 301 and the slot 103 are used to fix the placement box 300 and the box body 100. It also includes a battery pack 500, which is arranged in the placement box 300. The battery pack 500 is used to provide power for the air pump 200.

[0052] In this embodiment, through the mutual cooperation of the slot 103 on the box body 100 and the plug-in part 301 on the placement box 300, it is ensured that the placement box 300 is firmly fixed above the box body 100. Such a design is not only convenient for installation and disassembly, but also can maintain good stability during the operation of the device, avoiding vibration or movement, thereby ensuring the continuity and effectiveness of the operation of the air pump 200.

[0053] The battery pack 500 powers the air pump 200, making the entire purification system a self - contained unit that can operate for a period without an external power source, enhancing the system's independence and its ability to handle emergencies.

[0054] Furthermore, the liquid level inside the box body 100 is lower than the air outlet 102.

[0055] In this embodiment, the air outlet 102 being higher than the liquid level simplifies the gas discharge path. The gas can directly pass through the air outlet 102 from below the liquid level without the need for additional isolation or sealing devices to prevent the liquid from escaping with the gas, reducing the structural complexity and manufacturing cost.

[0056] Furthermore, the placement box 300 also has a second opening 302. The air inlet end of the air pump 200 is connected to the second opening 302. A filter screen 600 is also included and is arranged at the second opening 302. The filter screen 600 is used to preliminarily filter the air entering the air pump 200.

[0057] In this embodiment, the additional second opening 302 on the placement box 300 is for the air intake of the air pump 200, and the filter screen 600 arranged at the second opening 302 serves the duty of preliminary filtration. This design can effectively block larger dust particles, insects, hairs and other impurities, preventing them from directly entering the interior of the air pump 200, thus reducing the maintenance requirements of the air pump 200 and extending its service life.

[0058] Furthermore, the box body 100 includes a main body 110. The main body 110 has an air inlet 101 and a slot 103. The placement box 300 is detachably arranged on the main body 110. A cover body 120 is arranged on the top of the main body 110, and the air outlet 102 is located on the cover body 120.

[0059] In this embodiment, the setting of the cover body 120 not only provides a position for the air outlet 102 but also has a sealing function to prevent external pollutants from entering the box body 100. At the same time, when replacing the liquid, the cover body 120 can be removed so that the liquid can be poured out, increasing the practicality.

[0060] Furthermore, the main body 110 and the cover body 120 are hermetically connected. A handle 121 is also included and is arranged on the outer side of the cover body 120.

[0061] In this embodiment, the hermetic connection between the main body 110 and the cover body 120 ensures that during the operation of the air filtration device, the unpurified external air will not directly leak into the purified air output end. At the same time, it also prevents the evaporation or splashing of the internal purification liquid, maintaining the system's enclosure and purification efficiency. Sealing is crucial for maintaining the internal air pressure stability, preventing pollutant intrusion and keeping the liquid level stable.

[0062] The addition of the handle 121 makes it easier to separate the main body 110 from the cover 120, facilitating the operator to pull the cover 120 off the main body 110.

[0063] Embodiment Two

[0064] Referring to Figures 4 to 6 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that it further includes a first partition 700 disposed inside the main body 110. The first partition 700 is used to divide the internal space of the main body 110 into two first independent spaces; a second partition 800 is disposed inside the first extension pipe 400. The second partition 800 is used to divide the interior of the first extension pipe 400 into two second independent channels, and the two first independent spaces and the two second independent channels are respectively connected.

[0065] In this embodiment, by alternately using the two independent spaces, it can be ensured that while one space is working, the purification liquid in the other space can be static or maintained, such as replenished, replaced, or cleaned, so as to always keep the purification liquid in at least one space in the best working state. In this way, even during long-term operation, the stability of the air purification quality can be maintained, avoiding fluctuations in the filtration quality caused by the decline in the efficacy of the purification liquid after long-term use.

[0066] Furthermore, the first extension pipe 400 is cylindrical and further includes a rotating plate 900 rotatably disposed inside the first extension pipe 400. After the rotating plate 900 rotates, one of the second independent channels is opened and the other second independent channel is closed.

[0067] In this embodiment, the cylindrical design of the first extension pipe 400 simplifies the manufacturing process of the pipe fittings, which is conducive to standardized production and cost reduction. The introduction of the rotating plate 900 enables the switching from one independent channel to another through a simple rotation action, without complex mechanical operations, improving work efficiency.

[0068] The rotation axis of the rotating plate 900 and the axis of the first extension pipe 400 can be designed to be parallel or perpendicular. Such a design flexibility can adapt to different installation spaces and usage requirements. The parallel configuration may be more suitable for environments with limited space, while the perpendicular configuration may be more convenient for maintenance and operation.

[0069] Furthermore, the rotation axis of the rotating plate 900 is perpendicular to the axis of the first extension tube 400, and the rotating plate 900 includes a rotating shaft 910, which is rotatably arranged in the first extension tube 400; the first semicircular plate 920 is arranged on the rotating shaft 910; the second semicircular plate 930 is arranged on the rotating shaft 910, and the first semicircular plate 920 and the second semicircular plate 930 are perpendicular to each other. After the rotating shaft 910 rotates, the first semicircular plate 920 opens a second independent channel, and the second semicircular plate 930 closes another second independent channel; the rotating switch 940 is arranged at one end of the rotating shaft 910, and the rotating switch 940 is used to rotate the rotating shaft 910.

[0070] In this embodiment, the rotating shaft 910 is arranged perpendicular to the axis of the first extension tube 400. This design enables the rotating plate 900 to switch between two independent channels within a limited space, thereby avoiding interference with the connection between the first extension tube 400 and the air pump 200 when an external operator operates the rotating plate 900 to rotate.

[0071] The first semicircular plate 920 and the second semicircular plate 930 are respectively mounted on the rotating shaft 910 and are perpendicular to each other. This design allows one semicircular plate to open the corresponding independent channel when the rotating shaft 910 rotates, while the other semicircular plate closes the channel opposite to it. This ingenious mechanical structure can complete the channel switching by only a 90-degree rotation, simplifying the operation process and improving the flexibility and response speed of the system.

[0072] The rotary switch 940 provided at one end of the rotating shaft 910 is a control element for realizing channel switching. The operator can manually rotate the switch to drive the rotating shaft 910 to rotate a corresponding angle, thereby controlling the opening and closing of the first semicircular plate 920 and the second semicircular plate 930 to realize rapid switching of channels. Such a design is easy to operate, reduces the dependence on complex control systems, and improves the usability and maintenance convenience of the equipment. The rotary switch 940 is arranged on the outside of the placement box 300, which is more convenient for the operator to operate.

[0073] Furthermore, the second partition 800 has a semicircular groove 810. After the rotating shaft 910 rotates, the first semicircular plate 920 or the second semicircular plate 930 is located in the groove 810, and after the first semicircular plate 920 or the second semicircular plate 930 enters the groove 810, the first semicircular plate 920 or the second semicircular plate 930 and the second partition 800 separate two second independent channels.

[0074] In this embodiment, the semicircular groove 810 on the second partition 800 is precisely matched with the first semicircular plate 920 or the second semicircular plate 930. When the rotating shaft 910 rotates so that the semicircular plate enters the groove 810, a tight physical seal is formed, which effectively isolates the air circulation between the two second independent channels, avoids air flow connection or leakage, and ensures the isolation and efficiency of the purification process.

[0075] The design of the semi-circular groove 810 not only serves as a positioning point for channel switching, but also increases the stability during the rotation process, ensuring that the semi-circular plate can be accurately inserted into the groove 810 when the rotation is in place, improving the accuracy and reliability of channel switching, and reducing the problem of inaccurate air flow control that may be caused by position deviation.

[0076] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
