Embodiment 1

[0053]Such asFigure 1 to 6As shown, a chair of the head assembly provided in this embodiment, including: the first wind chamber 1, and there is a wind outlet 11 on the circumferential surface; windshield 2, activity is disposed in the first wind frame 1 At; driving assembly, the windshield 2 is driven according to the driving assembly having the first state that extends into the first wind chamber to close the air outlet 11 and the second wind frame 1 to open the air outlet 11 status.

[0054]The head assembly in this embodiment is a head assembly on the air cycle fan. As a deformation, it can also be a head structure such as a fan, a flying fan.

[0055]Such asfigure 1 As shown, the head assembly in the present embodiment includes a lower housing structure, and a fan assembly 5 is mounted in the lower housing, and the fan assembly 5 includes a fan fixed to the housing and an impeller mounted on the fan shaft. The grid-shaped feeding structure is processed at the lower end of the housing....

Embodiment 2

[0067]In this embodiment, a fan includes a head assembly and a base in the above embodiment, and the head assembly is mounted on the base, and all of the technical advantages of the above-described head assembly are not described herein.

Abstract

The invention relates to the technical field of household appliances, in particular to a machine head assembly and a fan. The machine head assembly comprises a first air duct frame, an air blocking piece and a driving assembly, wherein an air outlet is formed in the circumferential face of the first air duct frame; the air blocking piece is movably arranged at the first air duct frame; and the air blocking piece has a first state of extending into the first air duct frame to close the air outlet and a second state of separating from the first air duct frame to open the air outlet under the action of the driving assembly. The air blocking piece is arranged in the machine head assembly and can open and close the air outlet formed in the circumferential face of the first air duct frame under the action of the driving assembly; and when a user does not need to exhaust air in the circumferential direction, the air blocking piece closes the air outlet under the action of the driving assembly, and therefore foreign matter such as outside dust can be effectively prevented from entering the fan.

Description

Technical field[0001]The present invention relates to the field of fan technology, and more particularly to a head assembly, a fan.Background technique[0002]The conventional fan of the traditional fan is more than one, mostly the wind-oriented winds. In order to increase the wind range, the head assembly is increasing around the base to increase the winding range around the chassis of the head assembly and the base of the fan.[0003]However, the way of shaking head is generally unable to achieve circumferential 360 degree shaking head function, and the angle of shaking head is limited. In the prior art, the flow path of the circumferential airway is constructed in the head assembly, and the circumferential direction of the wind turning on the wind turbine is connected to the circumferential wind direction, the fan is 360 degrees. The outlet function.[0004]However, the setting of the circumferential grid increases the area of ​​the overall air outlet of the fan, causing foreign matter...
