In an embodiment, referring to FIGS. 14 and 15. FIG. 14 is a schematic sectional view of the wall-mounted air purifier 100 of this embodiment. FIG. 15 is a schematic diagram of the transmitting head of this embodiment. In this embodiment, the wall-mounted air purifier 100 also includes a negative ion generator 53, which has a transmitting head 530, and the transmitting head 530 of the negative ion generator 53 is arranged at a position corresponding to the air outlet 115, so that the air flow generated by the fan 31 passes through the transmitting head 530 of the negative ion generator 53 and then flows out of the air outlet 115 to form an airflow with negative ions to better disinfect and purify the air.

In one embodiment, the transmitting head 530 includes a negative ion release brush 531, a support 532, and two guide plates 533. The support 532 is installed on the housing 10, and the negative ion release brush 531 is installed on the support 532. The negative ion release brush 531 is supported by the support 532, and the negative ion release brush 531 extends to the air outlet 115. The two guide plates 533 are respectively arranged opposite to the negative ion release brush 531. On both sides, the distance between the two guide plates 533 gradually expands from the middle of the guide plate 533 downwards, that is, the distance between the two guide plates 533 expands gradually from the middle of the guide plate 533 to the lower side of the guide plate 533. So that the space between the lower parts of the two guide plates 533 gradually increases, and the air flow to the lower part of the two guide plates 533 will slow down and diffuse, so that the negative ions in the air flow can be better diffused to increase the area covered by the negative ions.

In one embodiment, the guide plate 533 and the support 532 are fixedly connected to facilitate the installation and fixation of the guide plate 533, and further facilitate the installation and fixation of the transmitting head 530. In some embodiments, the guide plate 533 can also be separately supported in the housing 10.

In one embodiment, the distance between the two guide plates 533 is gradually expanded upward from the middle of the guide plate 533, that is, the distance between the two guide plates 533 is gradually expanded from the middle of the guide plate 533 to the upper side of the guide plate 533 to allow more air to enter between the two guide plates 533 and to make more air contact the negative ion release brush 531 to generate more negative ions.

In one embodiment, the distance between the upper sides of the two guide plates 533 is smaller than the distance between the lower sides of the two guide plates 533, so as to ensure that the airflow velocity from the lower sides of the two guide plates 533 is less than that of the airflow outside the two outer guide plates 533, which will form a certain siphon effect on the lower side of the two guide plates 533 to better diffuse the negative ions in the air flow between the two guide plates 533, thereby increasing the area covered by the negative ions.

In one embodiment, the negative ion release brush 531 is arranged at a position corresponding to above the middle of the guide plate 533, so that more air flow passes through the negative ion release brush 531, and then is guided and diffused by the guide plate 533.

In one embodiment, the negative ion release brush 531 extends obliquely upward, that is, the negative ion release brush 531 extends obliquely upward from the support 532 to the free end of the negative ion release brush 531. Since the free end of the negative ion release brush 531 is relatively more open, the extending the negative ion release brush 531 obliquely upwards can reduce the resistance of the negative ion release brush 531 to the air flow, thereby facilitating the air flow through the negative ion release brush 531 to produce more negative ions.

In an embodiment, referring to FIG. 16, which is a schematic sectional view of the wall-mounted air purifier 100 of this embodiment, the ultraviolet light source 41 is arranged between the fan 31 and the filter 21, and the air filtered and purified by the filter 21 is then irradiated and disinfected by the ultraviolet light source 41 to ensure the purification effect of the air. In addition, the ultraviolet light source 41 is arranged between the fan 31 and the filter 21, and the filter 21 can also be used to block the ultraviolet light to prevent the ultraviolet light from leaking from the air inlet 112.

In one embodiment, referring to FIG. 16, the light shield 42 is provided with a third opening 425 so that the air entering the light shield 42 after being filtered by the filter 21 can better flow to the fan 31 and reduce the air resistance.

In one embodiment, referring to FIG. 17, which is a perspective schematic diagram of the wall-mounted air purifier 100 of this embodiment, the socket 116 is arranged at the bottom of the housing 10, the socket 116 is provided with a sliding plate 117, and the sliding plate 117 is slidably installed at the bottom of the housing 10. When the filter 21 is inserted into the housing 10 through the socket 116, the sliding plate 117 can be pulled out so that the sliding plate 117 supports the filter 21; When disassembling the filter 21, sliding the sliding plate 117 so that the sliding plate 117 is received in the housing 10, in order to remove the filter 21.

In one embodiment, referring to FIG. 5 and FIG. 17, the ultraviolet tube 411 is detachably installed on the lamp holder 412, and the side of the housing 10 is provided with an opening window 123, and the housing 10 is provided with a cover plate 124 that covers the opening window 123. Arranging the opening window 123 on the housing 10 so that the ultraviolet tube 411 can be plugged and unplugged from the opening window 123 to facilitate the replacement of the ultraviolet tube 411.

The wall-mounted air purifier 100 of the embodiment of the present application can not only filter purify, but also sterilize purify, and has a large air intake, which can provide purified air to the user's surroundings faster.

The above are only optional embodiments of the present application and are not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principles of the present application shall be within the protection scope of the present application.
