Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and in particular to a combined tower fan that is easy to store. Background Art

[0002] The tower fan "throws" the wind out through the crossflow fan to form an airflow, and the wind pressure is generated by the rotation of the wind wheel to generate centrifugal wind force, and finally the wind force is transmitted through the internal wind guide wall. Since the crossflow wind wheel is generally cylindrical, the tower fan is used to obtain a three-dimensional airflow wall, or a "wind curtain", which is perpendicular to the ground and swings left and right to blow. In addition, the crossflow wind wheel has many blades, and the air supply is uniform and soft, which is very close to the natural wind. Therefore, it is deeply loved by consumers for its soft wind output. The use environment of tower fans is mostly indoor environments such as living rooms. The existing combined tower fans are designed to have an air output range based on the height of the human body from the ground when standing. Therefore, the overall height of the combined tower fan is relatively high, which is inconvenient to move when transporting or placing it idle. The size requirements for the placement space are relatively high, and there are certain limitations. Utility Model Content

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 3 As shown, the combined tower fan of this embodiment, which is easy to store, includes several groups of tower fan modules 1 stacked in the vertical direction, any two adjacent groups of tower fan modules 1 are hingedly connected by a rotating mechanism 2, and a locking mechanism 3 is provided on the side away from the rotating mechanism 2 between any two adjacent groups of tower fan modules 1. The combined tower fan, which is easy to store, includes at least two groups of tower fan modules 1, and any two adjacent groups of tower fan modules 1 are hingedly connected by a rotating mechanism 2. In normal use, the two groups of tower fan modules 1 are stacked to achieve a larger air outlet range. In the state of transportation or idle placement, the two groups of tower fan modules 1 can be flipped and folded, which greatly improves the product's storability, reduces the overall height of the combined tower fan, and meets the requirements of a smaller placement space. It has a wide range of applications, high integration, and good compatibility. At the same time, a locking mechanism 3 is provided between any two adjacent groups of tower fan modules 1, and the two groups of tower fan modules 1 can be switched between a stacked state or a storage state through the locking mechanism 3, and the use flexibility is high.

[0024] It should be noted that when the combined tower fan includes three or more tower fan modules 1, the first rotating mechanism connecting the upper tower fan module and the middle tower fan module and the second rotating mechanism connecting the middle tower fan module and the lower tower fan module form an angle of a certain angle in the axial direction, and the angle of the angle meets the requirement of non-interference between the tower fan modules. Similarly, the first locking mechanism connecting the upper tower fan module and the middle tower fan module and the second locking mechanism connecting the middle tower fan module and the lower tower fan module also form an angle of a certain angle in the axial direction.

[0025] like Figure 4 As shown, preferably, the rotating mechanism 2 includes an articulated block 201 fixedly arranged on one group of tower fan modules 1 and an articulated seat 202 fixedly arranged on another group of tower fan modules 1, the articulated block 201 is provided with a rotating shaft 2011, the articulated seat 202 is provided with a limiting groove 2021 for accommodating the articulated block 201, and both sides of the articulated seat 202 are provided with articulated holes 2022 for the rotating shaft 2011 to pass through, which has the advantages of simple structure, convenient and quick assembly, and high maintenance efficiency.

[0026] Preferably, a rotation range limiting mechanism 4 is further provided between the articulated block 201 and the articulated seat 202 .

[0027] Preferably, the rotation range limiting mechanism 4 includes a limiting protrusion 401 provided on the hinge block 201 and a limiting groove 402 provided in the hinge seat 202, and the limiting protrusion 401 extends into the limiting groove 402 and cooperates with both ends of the limiting groove 402 to limit the rotation range of the hinge block 201. In this embodiment, the hinge block 201 is rotatably connected to the hinge seat 202. During the rotation of the hinge block 201, the limiting protrusion 401 can only move between the first end and the second end of the limiting groove 402, thereby limiting the hinge block 201 to only rotate between the first angle and the second angle. Specifically, it is set that the axes of two adjacent groups of tower fan modules 1 are parallel to each other as the first angle, and the axes of two adjacent groups of tower fan modules 1 are collinear as the second angle.

[0028] like Figure 5 As shown, preferably, the locking mechanism 3 includes an elastic locking tongue 301 fixedly arranged on one group of tower fan modules 1 and a buckle 302 fixedly arranged on another group of tower fan modules 1. By squeezing the elastic locking tongue 301 to cause elastic deformation, it is convenient to engage or disengage the elastic locking tongue 301 and the buckle 302, and the operation is convenient and quick. Specifically, the number of groups of the locking mechanism 3 between any two adjacent groups of tower fan modules 1 can be set to multiple groups, so as to further improve the connection stability between the tower fan modules 1.

[0029] Preferably, the tower fan module 1 includes a housing 101 and a cross-flow fan disposed in the housing 101, and the housing 101 is provided with an air inlet 102 and an air outlet 103. In this embodiment, each group of tower fan modules 1 is independent of each other and can be split into multiple groups of tower fan modules 1 for independent use. The specific structure and function are the same as those of the tower fan in the prior art, and will not be described in detail here. The user can stack any multiple groups of tower fan modules 1 in the vertical direction according to the use requirements to obtain a flexible air outlet range.

[0030] Preferably, a base 5 is provided at the bottom of the tower fan module 1 at the bottom layer, which can improve the stability of the combined tower fan, prevent the tower fan module 1 from tilting and overturning, and improve the safety of use.

[0031] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. For those skilled in the art, improvements and changes obtained without departing from the technical concept of the present invention should also be regarded as the protection scope of the present invention.
