Description

Technical Field

[0001] The utility model relates to the field of air purification equipment, in particular to a gas diffusion device. Background Art

[0002] At present, in order to remove air pollutants such as bacteria, odors and harmful chemicals in indoor air, air purifiers are usually installed indoors to purify the air in the room. Chinese patent literature discloses a technical solution with patent number 201710055746.6 and the name of "an air purification fan", which mainly includes a base, a fuselage, a head, an electric horizontal rotation mechanism, and a manual pitch rotation mechanism, wherein the fuselage can be horizontally rotatably connected to the base through an electric horizontal rotation mechanism, and the head can be pitch-rotatably connected to the fuselage through a manual pitch rotation mechanism, and the head includes a casing with an air inlet and an air outlet and a fan, and a plurality of filter layers arranged in the casing. When in use, the outside air is sucked in by the fan, so that the outside air flows into the inside of the casing from the air inlet, and then the air is discharged from the air outlet after being filtered by multiple layers of filters. Although this kind of air purifier has a very good air purification effect, in actual use, this kind of air purifier still has the following shortcomings:

[0003] First, since this type of air purifier uses multiple filter layers to achieve air filtration and purification, and most of the existing filter layers are thicker filter structures, and their mesh holes are very fine and arranged in a criss-cross pattern, the wind resistance is large, so that the air cannot pass through the filter layers quickly. In this way, a high-power fan is needed to draw air to increase the air flow rate, but the operation noise of the high-power fan is loud, which affects the user experience.

[0004] Secondly, since this type of air purifier uses a manual pitch rotation mechanism to achieve the pitch rotation of the head, when using it, the user is required to manually adjust the pitch angle of the head, which is not convenient to use and also affects the user experience.

[0005] Therefore, in view of the above-mentioned shortcomings and deficiencies of the existing air purifiers, the applicant believes that it is very necessary to optimize and improve their structure in order to better meet people's application needs. Summary of the invention

[0006] The purpose of the utility model is to solve the above-mentioned problems and shortcomings and to provide an automatic multi-angle gas diffusion device, which adopts an ultraviolet light purification channel to achieve air purification. It not only has small wind resistance, fast air circulation speed and high indoor air purification efficiency, but also enables the gas diffusion device to use a low-power fan to draw air to reduce the operating noise of the fan. At the same time, the pitch angle and horizontal angle of the casing can be automatically adjusted, and the user experience is good.

[0007] The technical solution of the utility model is implemented as follows: an automatic multi-angle gas diffusion device, including a casing with an air inlet and an air outlet and a fan, a bracket, a base, and an electric horizontal rotation mechanism. The bracket can be horizontally rotatably connected to the base through the electric horizontal rotation mechanism. Its characteristic is that it also includes an electric pitch rotation mechanism. The casing can be pitch-rotatably connected to the bracket through the electric pitch rotation mechanism. An ultraviolet light purification channel respectively connected to the air inlet and the air outlet is also provided in the casing.

[0008] Preferably, the ultraviolet light purification channel is a long strip channel structure.

[0009] Preferably, an ultraviolet light purification module is provided in the housing, and the ultraviolet light purification channel is arranged on the ultraviolet light purification module.

[0010] Preferably, the housing includes a shell and a fixing frame arranged in the shell, the air inlet and the air outlet are respectively arranged on the shell, and the ultraviolet light purification module is arranged in the shell by being fixed on the fixing frame.

[0011] Preferably, the fixing frame is a U-shaped frame having a U-shaped cavity, the ultraviolet light purification module is arranged in the U-shaped cavity, the outer wall of the U-shaped frame is provided with a through hole for air to flow into the ultraviolet light purification channel, and the axial center line of the air inlet, the through hole, the ultraviolet light purification channel and the air outlet is coaxially arranged.

[0012] Preferably, the cavity opening of the U-shaped cavity is provided with a clamping piece for clamping and fixing one end of the ultraviolet light purification module, and the cavity bottom of the U-shaped cavity is provided with a clamping frame for clamping and fixing the other end of the ultraviolet light purification module.

[0013] The beneficial effects of the utility model are as follows: since the utility model adopts an ultraviolet light purification channel to achieve air purification, it can greatly reduce the wind resistance caused to the air, increase the speed of air circulation, and thus improve the efficiency of indoor air purification. Moreover, since the wind resistance is small, a low-power fan can be used to draw air, so that the operating noise of the fan can be greatly reduced, and the user's experience can be improved. In addition, since the casing of the utility model is connected to the bracket in a pitch-rotating manner through an electric pitch rotation mechanism, and the bracket of the utility model is connected to the base in a horizontally rotatable manner through an electric horizontal rotation mechanism, when in use, the purpose of electrically adjusting the pitch rotation angle of the casing can be achieved, and the purpose of electrically adjusting the horizontal rotation angle of the casing and the bracket can also be achieved, so that the gas diffusion device can achieve the purpose of automatically adjusting the air outlet direction at multiple angles, which is very convenient to use and greatly improves the user's experience.

In this way, the structure of the fixing frame can be simpler, easy to manufacture, will not affect the air flow into the ultraviolet light purification channel 70, and ensure that the air inflow and outflow are very smooth.

[0022] In order to make the ultraviolet light purification module 7 more firmly arranged in the U-shaped cavity 141, Figure 2 and Figure 3 As shown, the cavity mouth of the U-shaped cavity 141 is provided with a clamping piece 142 for clamping and fixing one end of the ultraviolet light purification module 7, and the cavity bottom of the U-shaped cavity 141 is provided with a clamping frame 143 for clamping and fixing the other end of the ultraviolet light purification module 7. In this way, the two ends of the ultraviolet light purification module 7 can be clamped and limited respectively, so that the ultraviolet light purification module 7 will not shake or loosen at will, improve the stability of the ultraviolet light purification module 7 installed in the U-shaped cavity 141, and will not affect the smoothness of air flow, and improve the reliability of the use of the gas diffusion device. Specifically, the number of the clamping pieces 142 is two, and the two clamping pieces 142 are respectively arranged at the two ends of the cavity mouth of the U-shaped cavity 141.

Through such a structural design, not only can the structure of the ultraviolet light purification module 7 be very simple, scientific, reasonable, and easy to manufacture, but also the ultraviolet light purification channel 70 can be manufactured more easily. Through the setting of the cylindrical body 71, the wind energy in the housing 13 can easily flow into the cylindrical body 71. Through the setting of the connecting frame 72, the ultraviolet germicidal lamp 73 can be firmly installed in the cylindrical body 71. Through the setting of the ultraviolet germicidal lamp 73, air pollutants such as odor, formaldehyde, bacteria, allergens, etc. in the air can be purified and eliminated, thereby playing a role in purifying the air.
