Deflexion rod umbrella and folding electric fan using in match with the same

Abstract

The invention discloses a partial pole umbrella and a matching folding electric fan. The partial pole umbrella includes an umbrella pole, an umbrella rib, an umbrella surface and an umbrella cap. The umbrella cap is located at the center of the umbrella, and the umbrella skeleton supports the umbrella surface. The umbrella The ribs are composed of a plurality of main ribs and a plurality of auxiliary ribs, among which the plurality of main ribs are respectively hinged with the umbrella cap, and are distributed in a centrally symmetrical divergent shape, and the umbrella pole is composed of the main umbrella pole and the auxiliary umbrella pole. , wherein the main umbrella pole is connected to one of the main umbrella ribs, one end of the auxiliary umbrella pole is connected to the main umbrella pole, and the other end is connected to the main umbrella pole connected to the main umbrella pole. The symmetrical main umbrella ribs are connected, the main umbrella pole deviates from the center of the umbrella, and the center line of the main umbrella pole is parallel to the center line of the umbrella cap. The umbrella rib of the umbrella has better supporting function. The folding electric fan used in conjunction with the above-mentioned partial pole umbrella includes a motor bracket, a motor, a fan core and fan blades, and the motor bracket is installed on the lower end of the umbrella cap or on the auxiliary umbrella pole.

Description

technical field [0001] The invention relates to a daily appliance, in particular to an off-pole umbrella. The invention also relates to a folding electric fan matched with the off-pole umbrella. Background technique [0002] Umbrella is one of the important daily utensils for people. It is mainly composed of umbrella pole, umbrella rib, umbrella surface and umbrella cap. It is a center-symmetric arc shape, and the ribs are also center-symmetric divergent. The umbrella shaft is located at the center of the umbrella, and its center line coincides with the center line of the umbrella cap. This kind of umbrella is easy to fold, but this symmetrical shape The umbrella has the following problems: because the umbrella pole of the umbrella is all at the very center of the umbrella, the central position of the umbrella should be the position where the user is, but due to the structure of the umbrella, this position limits the use of the user. Therefore, the effective area of ​​the u...

Problems solved by technology

[0002] Umbrella is one of the important daily utensils for people. It is mainly composed of umbrella pole, umbrella rib, umbrella surface and umbrella cap. It is a center-symmetric arc shape, and the ribs are also center-symmetric divergent. The umbrella shaft is located at the center of the umbrella, and its center line coincides with the center line of the umbrella cap. This kind of umbrella is easy to fold, but this symmetrical shape The umbrella has the following problems: because the umbrella pole of the umbrella is all at the very center of the umbrella, the central position of the umbrella should be the position where the user is, but due to the structure of the umbrella, this position limits the use of the user. , it is impossible to use the effective area of ​​the umbrella reasonably and effectively to serve the user, and the function of the umbrella cannot be brought into full play.

[0004] 1) In the above-mentioned eccentric umbrella, since the lengths of the ribs supporting the umbrella surface are not equal, when the umbrella is in the open state, the force received by each rib is unequal, which easily leads to the breaking of the ribs

[0005] 2) Due to the uneven length of the umbrella ribs, different umbrella ribs need to be produced according to the length of the umbrella ribs in the process of manufacturing the umbrella ribs, which increases the processing steps, reduces the production efficiency, and increases the processing cost at the same time

[0006] 3) The umbrella handle of the umbrella coincides with the center line of the umbrella cap, and the umbrella handle deviates from the center of the umbrella surface, so that the umbrella cap also deviates from the center of the umbrella surface. Since each umbrella rib has one end hinged on the umbrella cap, and With the umbrella cap as the center, it is radially distributed. When subjected to strong wind or heavy rain, the external force cannot be evenly distributed to each rib, and the ribs are easily deformed or even damaged, which poses a certain safety hazard.

[0007] And above-mentioned umbrella only plays the effect of blocking sunlight for the user when using in sunny day, and umbrella itself does not have air-supply device, thereby also does not have air-supply function
