Description

Technical Field

[0001] The utility model relates to a fan, in particular to a child safety protection fan. Background Art

[0002] Although air conditioners are becoming increasingly popular and widely used, fans remain a common and widely accepted cooling method in the summer. Traditional fan covers feature multiple metal wires arranged radiating from the center. This radial arrangement results in large gaps between the wires at the edges of the fan cover. While these large gaps ensure optimal airflow and provide significant protection, they are not safe for small children. The large gaps are wide enough for children's fingers to penetrate, posing a safety hazard. Utility Model Content

[0003] The purpose of the present utility model is to provide a child safety protection fan to solve the problems raised in the above background technology.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figures 1 to 3 In the embodiment of the present invention, a child safety protection fan comprises a fan body 9

[0017] The fan body 9 includes a slot 1, a fan cover net 2, an additional ring 3 and a protective blade 4;

[0018] The middle of one side of the fan cover net 2 is fixedly connected to the motor, and the output end of the motor is connected to the fan blades in the fan cover net 2. In addition, the fan cover net 2 is connected to the carrier through the bracket 5, and the motor is electrically connected to the power supply through the switch.

[0019] The above components are components in the fan body 9, among which the motor, fan blades and control circuit can also adopt other existing technologies, which will not be described in detail in this application.

[0020] The fan cover 2 of the fan body 9 is provided with a plurality of annularly distributed protective blades 4 near the edge thereof. The fan cover 2 includes a front cover and a rear cover (this is a common cover structure for existing fans), and a plurality of protective blades 4 are provided near the edge of each of the front and rear covers. The protective blades 4 shield the areas with larger gaps on the fan cover 2 to prevent children's fingers from getting into the area.

[0021] The protective blades 4 are rotatably mounted on the additional annular member 3. There are two additional annular members 3 fixedly connected by screws. The two additional annular members 3 are distributed at the edges of the front mesh cover and the rear mesh cover, and the two additional annular members 3 clamp the edge positions of the fan cover net 2 to achieve positioning.

[0022] The protective blades 4 include a metal frame 12 and a mesh surface 13. The metal frame 12 is bent into an arc shape and the two ends of the metal frame 12 are bent outward to form a mesh surface 13. The area enclosed by the arc portion of the metal frame 12 is provided with a mesh surface 13 (it should be noted that the mesh holes on the mesh surface are smaller than the thinnest part of a child's finger, and can generally be set to 1-3 mm. In order to ensure the ventilation volume of the fan main body 9 as much as possible, they can be densely arranged). The edges of the mesh surface 13 can be fixedly connected to the surface of the metal frame 12 by welding; the two ends of the metal frame 12 are rotatably set in the corresponding rotating holes 10 opened on the surface of the corresponding additional ring member 3; the above structure allows the protective blades 4 to be opened to ensure the original air volume.

[0023] Furthermore, the mesh surface 13 may also be a plate without holes.

[0024] Furthermore, in order to increase safety, the mesh surface 13 can be tied to the fan cover net 2 by a rope. This binding method can be untied, which is also convenient for children to use the fan normally after they grow up.

[0025] The main structure of the additional annular member 3 is an annular profile.

[0026] Furthermore, the end surface of the additional ring member 3 is provided with a plurality of slots 1; Figure 2 One side of the slot 1 passes through the inner surface of the additional ring 3, and a rotating hole 10 is opened on the side wall of the slot 1. The surface where the axis of the rotating hole 10 is located is parallel to the end face of the additional ring 3, and the end of the protective blade 4 rotates in the rotating hole 10.

[0027] Furthermore, a circle of multiple protective blades 4 arranged on the surface of the fan cover net 2 can be arranged to overlap end to end to increase the force to pry it apart from a point, thereby increasing the difficulty for children to pry it apart and improving the protective effect.

[0028] like Figure 1 If it is a traditional vertical fan, the fan body 9 is connected to the base 6 through the bracket 5.

[0029] The surface of the bracket 5 of the fan body 9 is fixedly connected to the annular seat 7, and a plurality of through holes are provided on the outer surface of the annular seat 7. One end of a limiting rod 8 is inserted into the through hole. The limiting rod 8 is made of plastic foam. By selecting the length of the limiting rod 8, children can be restricted from approaching and their attention can be distracted.

[0030] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
