Example 1

As shown in fig. 1 to 4, the fan provided in this embodiment includes a base 1 and a head assembly 2, a connecting member 3 is disposed at an end surface of the head assembly 2 facing the base 1, at least one first sliding structure 31 is formed on the connecting member 3, and a second sliding structure 11 matched with the first sliding structure 31 is integrally formed on the base 1.

The fan in this embodiment is a circulating fan, and the head assembly 2 can adjust the pitch angle on the base 1, so as to increase the range of air outlet. As a modification, the fan may be a common desk fan, a floor fan, or the like.

The base in this embodiment is common support circulating fan's head assembly's supporting seat structure, and it is mostly integrative injection moulding's round platform column structure, and the base is inside to be provided with corresponding strengthening rib structure to guarantee the stability of support.

Head assembly 2 in this embodiment includes the casing and sets up the fan in the casing, and the fan drives the fan blade and rotates and realize the convulsions function.

The connector 3 in this embodiment is designed as a conventional support arm structure, which can be integrally formed directly on the housing of the head assembly 2 to simplify installation. As a variant, the support arm can also be detachably mounted on the housing of the head assembly 2 for maintenance convenience, since the structural strength at the location of the connection piece is relatively weak, the frequency of maintenance is high, the detachable design can simplify manual maintenance.

In this embodiment, the connection part between the base 1 and the handpiece assembly 2 is provided with the connecting part 3, and the first sliding structure 31 on the connecting part 3 is matched with the second sliding structure 11 on the base 1, so that the handpiece assembly 2 can be rotatably mounted on the base 1. Further, first sliding structure 31 is integrated into one piece on connecting piece 3, and second sliding structure 11 is integrated into one piece on the base, compares in the mode that needs installation slide rail and support seat among the prior art, and only need during the equipment in this embodiment with first sliding structure 31 and second sliding structure 11 equipment cooperation can, simple structure, the packaging efficiency height.

On the basis of the above-described embodiment, as a further limitation, the first sliding structure 31 is configured as a sliding groove disposed along the rotation direction of the head assembly 2, the sliding groove is machined on the peripheral wall of the connecting piece 3, and the second sliding structure 11 is configured as a sliding block clamped on the sliding groove, and the sliding block is integrally molded on the end surface of the base. In the installation of base 1 and head assembly 2, only need clamp the slider and adorn in the spout, can realize the installation of head assembly 2 on base 1, the installation degree of difficulty is low and simple, and the structural style of slider and spout, simple structure, and the processing cost is low. As a variant, the first sliding structure 31 is configured as a slider and the second sliding structure 11 is configured as a runner disposed along the rotation direction of the handpiece assembly, which has the same implementation effect.

On the basis of the above embodiment, as a further limitation, the slider includes: the supporting portion 111 that the terminal surface integrated into one piece of protrusion base 1 set up, and supporting portion 111 grows up the strip, and in the direction of height, supporting portion 111 is suitable for stretching into the spout and sets up.
