[0034] Example

[0035] Please refer to Figure 1-Figure 7 The present embodiment provides a neck-hanging air purifier, comprising a neck-hanging body 1 and a mounting shell 2 arranged on the neck-hanging body 1, wherein a turbofan 3 and a filter 4 are arranged in the mounting shell 2, wherein the filter 4 of the present embodiment adopts a HEPA filter; an air inlet 5 is arranged on a side of the mounting shell 2 close to the turbofan 3, and an air outlet 6 is arranged on a side of the mounting shell 2 close to the filter 4.

[0036] The neck strap body 1 is provided with a mounting box 13, in which a battery 7 is provided, and the battery 7 is electrically connected to the turbofan 3, and the battery 7 is used to power the turbofan 3. Optionally, in this embodiment, a corresponding control switch 8, a charging head 14 and an indicator light 20 may be provided on the mounting box 13, the charging head 14 is used to connect a charger to charge the battery 7, the control switch 8 is used to control the start and stop of the turbofan 3, and the indicator light 20 is used to indicate when in use.

[0037] During actual use, the user can wear the neck strap body 1 on his or her neck, install the air outlet 6 of the outer shell 2 roughly opposite the user's mouth and nose, start the turbo fan 3, and the turbo fan 3 sucks external air from the air inlet 5 and blows the air through the filter 4. After the air is filtered by the filter 4, it is blown out from the air outlet 6 and blown towards the user's mouth and nose. In this way, the user can breathe the filtered air, and the clean air is directly breathed in to avoid mixing with the dirty air in the room.

[0038] Thus, the neck-hanging air purifier provided by the present application can be hung on the neck of the user, does not require an external power supply, is very portable, does not require air delivery equipment such as pipes, and does not cause inconvenience to the user; and can directly blow the filtered air to the user's mouth and nose at a close distance for the user to breathe, avoiding the need to purify the entire space. Moreover, the neck-hanging air purifier provided by the present application has a simple appearance, very similar to headphones, does not attract extra attention, and is relatively low-key.

[0039] like Figure 3-Figure 7 As shown, in some embodiments of the present invention, the mounting housing 2 is provided with a protective mesh cover 9 at the air outlet 6. The protective mesh cover 9 and the air outlet 6 are both circular, and the mounting housing 2 is provided with a plurality of snap-fitting protrusions 10 at the air outlet 6, and the side wall of the protective mesh cover 9 is provided with a plurality of L-shaped snap-fitting grooves 11; the snap-fitting protrusions 10 correspond to the snap-fitting grooves 11 one by one, and the snap-fitting protrusions 10 are embedded in the snap-fitting grooves 11.

[0040] The present invention can shield the filter 4 and other structures inside the mounting housing 2 by providing the protective mesh 9, thereby preventing the filter 4 from being touched. Furthermore, by providing a plurality of L-shaped snap-in grooves 11 on the side wall of the protective mesh 9, it is convenient to install the protective mesh 9 on the mounting housing 2, and also convenient to remove the protective mesh 9 from the mounting housing 2. When installing the protective mesh 9, it is only necessary to align the opening of the snap-in groove 11 of the protective mesh 9 with the snap-in protrusion 10, move the protective mesh 9 so that the snap-in protrusion 10 is embedded in the snap-in groove 11, and then rotate the protective mesh 9 to snap-in and lock it.

[0041] like Figure 1-Figure 2 As shown, in some embodiments of the present invention, the shape of the neck halter body 1 is U-shaped, and the mounting shell 2 and the mounting box 13 are respectively located at the two ends of the neck halter body 1. This makes it easy for the neck halter body 1 to be put on the neck of the user for wearing.

[0042] like Figure 1-Figure 2As shown, in some embodiments of the present invention, both ends of the mounting housing 2 are provided with connecting rods 12, and the mounting housing 2 and the mounting box 13 are respectively provided on the connecting rods 12. The present invention provides the connecting rod 12, and the connecting rod 12 can adopt the metal hose used in the existing table lamp and the neck hanging fan, so that the blowing angle of the air outlet 6 can be adjusted by the deformation of the connecting rod 12, so as to facilitate blowing the filtered air to the mouth and nose of the user.

[0043] like Figure 1-Figure 5 As shown, in some embodiments of the present invention, an indicator rod 15 is further included, and the protective net cover 9 is provided with a plug hole 16, and one end of the indicator rod 15 is inserted into the plug hole 16.

[0044] The present invention is provided with an indicator rod 15. When a novice wears the device, one end of the indicator rod 15 can be inserted into the insertion hole 16. In this way, the blowing direction of the protective net cover 9 can be determined by the direction of the indicator rod 15, and the distance between the indicator rod 15 and the user's nose can be determined to determine whether the distance of the protective net cover 9 is adjusted in place. That is, by adjusting the mounting housing 2 so that the indicator rod 15 is roughly aligned with the user's nose, when the indicator rod 15 is roughly against the user's nose, the air outlet 6 is not too far from the nose, and the effect is better.

[0045] like Figure 1-Figure 8 As shown, in some embodiments of the present invention, a baffle 17 is provided on the side of the mounting housing 2 close to the turbofan 3, and the baffle 17 is provided with a plurality of hooks 18; a plurality of hook holes 19 are provided on the side wall of the mounting housing 2, and the hooks 18 are embedded in the hook holes 19, the baffle 17 is spaced apart from the mounting housing 2, and the air inlet 5 is formed between the baffle 17 and the mounting housing 2. The present invention provides the baffle 17, so that the side of the mounting housing 2 close to the turbofan 3 is shielded by the baffle 17, so as to prevent external objects from touching the turbofan 3 inside the mounting housing 2, and the use is safer. Moreover, by providing the hooks 18 and the hook holes 19, when installing the baffle 17, it is convenient to install the baffle 17 on the side wall of the mounting housing 2 by embedding the hooks 18 in the hook holes 19, and the operation is convenient.
