Description

Technical Field

[0001] The utility model relates to the technical field of seat fans, and particularly to an improved assembly structure between the housing and the fan blade of a seat fan. Background Art

[0002] Currently, the fixing method between the housing and the fan blade of a seat fan mostly adopts the glue rubbing technology. Although this technology can meet the basic fixing requirements to a certain extent, its disadvantages are also very obvious. First of all, the glue rubbing fixing method is difficult to be effectively implemented on an automated production line because it usually requires manual operation, which not only increases the production cost but also reduces the production efficiency. Secondly, it is difficult to ensure the quality stability of the glue rubbing fixing because factors such as the amount of glue applied, the uniformity, and the drying degree of the glue will affect the fixing effect, which may cause problems such as loosening or falling off of the product during use. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide an improved assembly structure between the housing and the fan blade of a seat fan aiming at the above-mentioned deficiencies existing in the existing assembly between the seat fan and the fan blade using the glue rubbing fixing method. It adopts the plug-in hot melting connection between the housing and the fan blade to fix the housing, thus omitting the glue rubbing process.

[0004] The technical problem to be solved by the utility model can be achieved through the following technical solutions:

[0005] An improved assembly structure between the housing and the fan blade of a seat fan, including a fan blade and a housing. A housing mounting hole is provided at the center of the fan blade. The housing is in a cylindrical shape. It is characterized in that at least one hot melting plug is provided on the flange edge of the housing mounting hole; at least one ear seat is provided on the end face of one end of the housing arm of the housing, and a plug hole is provided on the ear seat; during assembly, the housing is inserted into the housing mounting hole, and the hot melting plug is inserted into the plug hole and hot melted, so that the housing and the fan blade are firmly fixed.

[0006] In a preferred embodiment of the utility model, the hot melting plug is in a stepped shape, the upper diameter is smaller than the lower diameter, and the upper diameter of the hot melting plug is inserted into the plug hole and hot melted.

[0007] In a preferred embodiment of the utility model, the lower surface of the ear seat is located on the stepped surface between the upper diameter and the lower diameter of the hot melting plug.

[0008] Due to the adoption of the above technical solution, a hot-melt plug is inserted into an ear seat between the fan blade and the casing of the present utility model for hot-melt connection, tightly combining the casing and the fan blade together. Compared with the traditional rubber rubbing process, the connection is more stable and reliable, and can avoid potential safety hazards caused by the aging and falling off of glue.

[0009] A hot-melt plug is inserted into an ear seat between the fan blade and the casing of the present utility model for hot-melt connection. This not only omits the cumbersome glue rubbing process, reduces production costs, but also improves production efficiency. During the manufacturing process, operators only need to operate according to the established processes and specifications to achieve precise connection between the casing and the fan blade, with good versatility and flexibility, and is applicable to fan products of different models and specifications.

[0013] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0014] Referring to Figures 1 to 3 , an improved assembly structure between the casing and the fan blade of a seat fan shown in the figure includes a fan blade 100 and a casing 200.

[0015] A casing mounting hole 110 is provided at the center of the fan blade 100. A plurality of hot-melt plugs 112 are circumferentially arranged on the flange 111 of the casing mounting hole 110. The hot-melt plugs 112 are in a stepped shape, with the upper diameter 112a smaller than the lower diameter 112b. A stepped surface 112c is provided at the connection between the upper diameter 112a and the lower diameter 112b of the hot-melt plug 112.

[0016] The casing 200 is in a cylindrical shape. A plurality of ear seats 220 are circumferentially arranged on the end face of one end 210 of the casing arm of the casing 200. A plug hole 221 is provided in each ear seat 220.

[0017] During assembly, the housing 200 is inserted into the housing mounting hole 110. The upper diameter 112a of the hot-melt pin 112 is inserted into the pin hole 221 and hot-melted, so that the housing 200 is firmly fixed to the fan blade 100. The lower surface 221a of the ear seat 220 is seated on the stepped surface 112c between the upper diameter 112a and the lower diameter 112b of the hot-melt pin 112.
