Description

Full-circle fan

The present invention relates to a fan, and more particularly to a fan that has a full circumferential wind.

Most of the existing fans have a oscillating head function, but there is a limitation of the use angle, and only a person in a specific area can be blown, and the air flow is constantly changed when the fan rotates with the oscillating function, which is easy to feel uncomfortable.

Therefore, it is an object of the present invention to provide a fan that can blow the entire circumferential direction of the wind in a full circumferential direction and stably.

Therefore, the novel full-circle fan includes a tripod unit, a housing unit, and a wind unit.

The tripod unit extends upward in an axial direction.

The housing unit is disposed above the tripod unit, and includes a hollow air collecting duct, an air inlet net plate disposed on the air collecting duct, a surrounding axial direction and a top edge of the collecting duct The air outlet network pipe, a top cover covering the top edge of the air outlet network pipe, and a receiving space defined by the air inlet mesh plate, the air outlet network pipe and the top cover, the air collecting pipe has a hollow A tubular section that surrounds the axial direction and has no voids in the peripheral wall.

The wind unit includes a motor disposed on the housing unit, and a set of blades located in the receiving space and driven by the motor.

The utility model has the advantages that the airflow from the collecting duct enters the accommodating space, so that the fan blades drive the wind to be stably blown out from the air outlet network pipe in the radial direction of the whole circumference, so as to surround the novel surrounding People can be battered by the wind and can avoid annoying unstable airflow.

Other features and effects of the present invention will be apparent from the following description of the drawings, wherein: FIG. 1 is a perspective view of a first embodiment of a novel full-circumferential wind fan; FIG. 3 is an exploded perspective view of the first embodiment; FIG. 3 is a partial cross-sectional view of the first embodiment; and FIG. 4 is a partial cross-sectional view of a second embodiment of the novel all-circumferential air outlet fan.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to FIGS. 1 to 3, a first embodiment of the present invention relates to a first embodiment of a fan that includes a tripod unit 2, a housing unit 3, a wind unit 4, and a heater 5.

The tripod unit 2 includes a base 21, and a post 22 disposed on the base 21 and extending upward in an axial direction X.

The housing unit 3 is disposed above the column 22 of the tripod unit 2, and includes a hollow air collection duct 31, an air inlet web 32 disposed on the air distribution duct 31, and a wind collecting duct 32 disposed on the air collecting duct An outlet network pipe 33 of 31, a top cover 34 covering the top edge of the air outlet network pipe 33, and a receiving space 35 defined by the air inlet mesh plate 32, the air outlet mesh pipe 33 and the top cover 34 . The collecting duct 31 has a tubular section 311 hollow around the axial direction X and having no voids in the peripheral wall, and a skirt section 312 extending downwardly and radially outward from the end edge of the tubular section 311. The inlet web 32 is substantially perpendicular to the axial direction X of the tubular section 311. The top cover 34 has a receiving portion 341 and a cap portion 342 extending radially outward from the periphery of the receiving portion 341. The outlet network pipe 33 has a squirrel-cage mesh shape, and the circumferential direction X overlaps the tubular section 311, and the top edge connects the cap portion 342 of the top cover 34, and allows the wind to pass radially. .

The wind unit 4 includes a motor 41 disposed on the receiving portion 341 of the top cover 34, a set of blades 42 located in the receiving space 35 and driven by the motor 41, and a motor 41 electrically connected to the motor 41. Switch 43. The set of blades 42 is an axial flow fan blade 42 that converts the axial incoming air into a radial blow.

The heater 5 is detachably disposed on the air inlet web 32 or the air outlet duct 33 and can be installed according to weather conditions. The Sky Cold Fashion is located on the air inlet stencil 32 and is used to heat the wind. When it is hot, it can be removed and stored. In the first embodiment, the heater 5 is an annular heating sheet and is mounted to the air inlet web 32 to heat the wind passing through the air inlet web 32. Preferably, the heater 5 can also be installed on the outlet network pipe 33 to heat the outlet. The wind of the wind network pipe 33. More preferably, when the air is cold, the heater 5 is installed on the air inlet stencil 32 and the air outlet net 33, and the wind passing through the air inlet slab 32 is preheated, and then the temperature is passed through the air stencil 32. The wind of the air outlet pipe 33 has the advantage that the temperature of the heater 5 is not too high, the power consumption is low, and the heat generation temperature is low, which is more energy-saving and safe.

The user can control the operation of the first embodiment through the switch 43, and the switch 43 is driven to drive the motor 41 to rotate the set of blades 42 to drive airflow from the collecting duct 31 along the axial direction X, through the air inlet. The stencil 32, through which the wind is pushed through the set of blades 42, is radially and stably blown out through the entire circumference of the air outlet duct 33.

When the weather is cold, the user turns on the heater 5 to warm the airflow to blow out the warm air.

Referring to FIG. 4, the structure of the second embodiment of the present invention is substantially similar to that of the first embodiment. The difference is that the housing unit 3 of the second embodiment is provided with a cover 36 and A wind deflector 37. The cover 36 is disposed under the air inlet web 32 and disposed on the upright 22 . The motor 41 is disposed inside the casing 36 instead. The air deflector 37 is disposed under the top cover 34 and extends outwardly from the center by symmetry of the axial direction X to guide the airflow to be blown out in the radial direction. In use, the motor 41 rotates the set of blades 42 to drive airflow from the lower side of the collecting duct 31 along the axial direction X, and guides the airflow through the air guiding plate 37 to be radially transmitted through the air outlet duct 33. The function of the full-cycle radial stable blowing of the first embodiment can also be achieved.

From the above description, it can be seen that the effect of the fan of the whole full-circumferential wind is:

1. The airflow is introduced into the accommodating space 35 through the collecting duct 31, and after the airflow is turned by the special design of the set of axial fan blades 42, the wind is stably blown out by the air outlet mesh pipe 33 in the radial direction. . The air inlet stencil 32 and the air outlet network tube 33 can not only isolate the set of blades 42 to protect the user, but also cooperate with the set of blades 42 to control the wind to pass through the air outlet duct 33 along the entire circumference. Blowing out, people around the new model can benefit and avoid interrupting annoying airflow.

2. The heater 5 is arranged in the present invention to facilitate the user to adjust the state of the weather to the state of cold air or hot air blowing.

The outer diameter of the cap portion 342 of the top cover 34 is larger than the set of blades 42 to prevent foreign matter or dust from falling into the accommodating space 35, thereby prolonging the service life of the set of blades 42.

In summary, the present invention can continuously blow cold and warm air along the entire circumference, so that the surrounding people can be stably blown by the wind without enduring the intermittent airflow, so the present invention can be achieved. purpose.

However, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made in accordance with the scope of the present patent application and the contents of the patent specification, All remain within the scope of this new patent.
