Fixing structure between casing and fan blades of seat fan

Abstract

The utility model discloses a fixing structure between a casing and a fan blade of a seat fan, which comprises the fan blade and the casing, and is characterized in that a plurality of large cylinders are arranged at the edge or proper positions of the fan blade, and the large cylinders are flattened and clung to the casing after being softened by hot pressing. According to the utility model, the five-point hot-pressing large cylinder is designed on the fan blade, and the problem of fixation is considered in advance in the design stage of the fan blade. A series of small cylinders are designed at the edges or proper positions of the fan blades, and when the fan blades and a machine shell are assembled, specific heating equipment is used for locally heating the cylinders, so that the cylinders are rapidly softened and deformed. Under proper pressure, the softened column body is flattened and tightly attached to an iron shell of the machine shell, and therefore stable connection between the fan blades and the machine shell is achieved. Compared with a traditional frictioning fixing mode, the hot-pressing column fixing method has many advantages.

Description

Technical Field

[0001] The utility model relates to the technical field of seat fans, in particular to a fixing structure between a casing and blades of a seat fan. Background Art

[0002] Although the traditional method of fixing the fan blades to the casing by gluing meets the basic needs of the product to a certain extent, it has many shortcomings in terms of automated production and quality stability.

[0003] First of all, the time cost problem brought by the glue fixation method cannot be ignored. In the production process of seat fans, once the fan blades and the casing are fixed by glue, it is necessary to wait for the glue to completely dry before proceeding to the subsequent process. This process is not only time-consuming, but also easily affected by factors such as ambient temperature and humidity, resulting in increased unpredictability of the production cycle. This not only reduces production efficiency, but also increases the production costs of enterprises.

[0004] Secondly, the way of fixing the glue makes the automated production line complicated and cumbersome. In modern manufacturing, automated production lines are the key to improving production efficiency. However, due to the introduction of the glue-rubbing process, the automated production line needs to add additional equipment and personnel to monitor and adjust the use of glue, which undoubtedly increases the complexity and maintenance cost of the production line. In addition, uncertainties in the glue-rubbing process may also cause pauses and failures in the production line, further affecting production efficiency.

[0005] Thirdly, the glue fixation method cannot guarantee the stability and consistency of the adhesive force. During the glue fixation process, it is difficult to accurately control the amount and distribution of glue, which will lead to different adhesive forces. During the use of the seat fan, this unstable adhesive force may cause the fan blades to loosen or fall off from the casing, which not only affects the product experience, but also may cause safety hazards.

[0006] Finally, the aging of the glue is also a potential threat. As time goes by and the usage environment changes, the glue may gradually age and lose its adhesiveness. Once the glue fails, the fixation between the fan blades and the housing will become unstable, which may cause equipment failure or parts to fall off. This will not only affect the service life of the seat fan, but may also pose a threat to the user's property and personal safety. Utility Model Content

[0007] The technical problem to be solved by the utility model is to provide a fixing structure between the casing and the fan blades of a seat fan which adopts a hot pressing method to fix the fan blades and the casing in order to solve the above-mentioned shortcomings of the existing glue fixing method between the fan blades and the casing.

[0008] The technical problem to be solved by the utility model can be achieved through the following technical solutions:

[0009] A fixing structure between a seat fan casing and blades comprises blades and a casing, and is characterized in that a plurality of large columns are arranged at the edge or appropriate position of the blades, and the large columns are softened by hot pressing, flattened and closely attached to the casing.

[0010] In a preferred embodiment of the present invention, the large cylinder is a rectangular large cylinder, which is softened by hot pressing to form a rectangular small cylinder tightly attached to the housing.

[0011] In a preferred embodiment of the present invention, the number of the large cylinders is five.

[0012] Due to the adoption of the above technical solution. The utility model adopts a five-point hot-pressed small column designed on the fan blade, and the fixation problem is considered in advance during the design stage of the fan blade. By designing a series of small columns on the edge or appropriate position of the fan blade, when the fan blade is assembled with the casing, a specific heating device is used to locally heat the column, so that it quickly softens and deforms. Under appropriate pressure, the softened column is flattened and fits tightly against the iron shell of the casing, thereby achieving a stable connection between the fan blade and the casing. Compared with the traditional glue fixing method, this hot-pressed column fixing method has many advantages:

[0013] 1. Greatly improve production efficiency. Since there is no need to wait for the glue to dry, the assembly process of the fan blade and the housing can be completed quickly, thus shortening the production cycle. In addition, the softening, deformation and fixing process of the hot pressing column can be achieved by automated equipment, further improving the automation level of the production line.

[0014] 2. The hot pressing column fixing method makes it easier to ensure product quality. Since the deformation of the column during the hot pressing process is uniform and controllable, the size and distribution of the bonding force between the fan blades and the casing can be guaranteed to be more consistent. This not only improves the reliability of the product, but also reduces the failure rate caused by uneven bonding force. In addition, the materials used for hot pressing columns usually have good heat resistance and aging resistance, which can ensure that the fixing effect between the fan blades and the casing will not weaken during long-term use.

[0015] 3. The hot pressing column fixing method also has the advantages of environmental protection and energy saving. Compared with the glue fixing method, it does not need to use a large amount of glue, thereby reducing the emission of chemical substances and pollution to the environment. At the same time, since the heating process can be completed in a short time, it also reduces energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS
