Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically a highly safe electric fan. Background Technology

[0002] An electric fan, also known as a fan or ventilator, is a household appliance that uses an electric motor to drive fan blades to rotate, thereby accelerating air circulation. It is primarily used for cooling and air circulation. It is widely used in homes, classrooms, offices, shops, hospitals, hotels, and other places.

[0003] Traditional electric fan shrouds are made of woven steel wires, with ventilation openings between the wires to facilitate airflow. However, the size of these ventilation openings typically increases gradually from the center outwards (as shown in the instruction manual). Figure 5 (As shown in the provided product image), children's fingers are thin and can easily be inserted into the ventilation openings near the outer edge of the fan cover, which can easily cause children's fingers to be hit and injured by the fan blades, resulting in poor safety. Summary of the Invention

[0004] The purpose of this utility model is to provide a highly safe electric fan to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-safety electric fan includes a head, a fan support rod, and a fan base. The fan base has a conical hollow structure and is filled with counterweight material. A suction cup is installed at the bottom of the fan base. A threaded hole is provided on the fan base, and the threaded hole is threadedly connected to a threaded connector installed at the bottom of the fan support rod. The head is installed on the fan support rod, and an anti-slap cover is provided on the outside of the head. The anti-slap cover includes a front cover and a rear cover, and a screw is provided between the front cover and the rear cover, and the two are fixedly connected by the screw.

[0007] As a further embodiment of this utility model: the head includes a fan head, a rod base, fan blades and a fan cover, the bottom of the fan head is equipped with a rod base, the rod base is inserted and fixed to the fan support rod, the output shaft of the fan head is equipped with fan blades, and the fan head is equipped with a fan cover.

[0008] As a further improvement of this utility model, the front cover and the rear cover together cover the outside of the fan cover.

[0009] As a further improvement of this utility model: the number of steel wires distributed in a ring on the front cover and the rear cover is equal to the number of steel wires distributed in a ring on the half cover of the fan cover.

[0010] As a further embodiment of this utility model: the fan support rod includes a rod cylinder, a rod body, and a locking handle. The rod body is movably inserted into the rod cylinder, and a locking handle for fixing the rod body is installed on one side of the rod cylinder.

[0011] As a further improvement of this invention, the counterweight material is sand, preferably fine sand.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model provides double protection by setting an anti-slap cover, which covers the outer edge of the fan cover (the closer to the outer edge of the fan cover, the larger the size of the grille holes, making it easier for children to insert their hands into the fan cover). A certain safety buffer space is formed between the fan cover and the anti-slap cover, so even if a child inserts their hand into the anti-slap cover, it is difficult for them to touch the fan blades, thereby reducing the probability of children being hit by the fan blades and improving the safety of the electric fan during use.

[0014] 2. This utility model increases the weight of the fan by setting a cone-shaped hollow fan base and inserting counterweight material inside the fan base, thereby lowering the center of gravity of the fan and making it more stable. At the same time, the suction cup installed on the fan base can stick to the ground when in contact with it, improving the firmness of the electric fan's contact with the ground, thus making the electric fan less likely to tip over and making it safer to use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1 and Figure 4 In this embodiment of the utility model, a highly safe electric fan includes a head 1, a fan support rod 2 and a fan base 3. The fan base 3 has a conical hollow structure and is filled with counterweight material 6. A suction cup 7 is installed at the bottom of the fan base 3. A threaded hole 5 is opened on the fan base 3, and the threaded hole 5 is threadedly connected to a threaded connector 4 installed at the bottom of the fan support rod 2.

[0023] The counterweight material 6 is sand, preferably fine sand. Fine sand is not only inexpensive and readily available, but also easy to load and unload and can be reused.

[0024] Please see Figure 1-3 The fan support rod 2 has a head 1 installed on it. The head 1 includes a fan head 101, a rod base 102, a fan blade 103, and a fan cover 104. The rod base 102 is installed at the bottom of the fan head 101 and is inserted and fixed to the fan support rod 2. The fan support rod 2 includes a rod cylinder 201, a rod body 202, and a locking handle 203. The rod body 202 is movably inserted into the rod cylinder 201. A locking handle 203 for fixing the rod body 202 is installed on one side of the rod cylinder 201. The fan support rod 2 can... The fan head 101 is telescopically adjustable to allow for easy height adjustment. The output shaft of the fan head 101 is equipped with fan blades 103 and a fan cover 104. An anti-slap cover 8 is provided on the outside of the head 1. The anti-slap cover 8 includes a front cover 801 and a rear cover 802. A screw 803 is provided between the front cover 801 and the rear cover 802, and the two are fixedly connected by the screw 803. The front cover 801 and the rear cover 802 together cover the outside of the fan cover 104.

[0025] The number of steel wires distributed in a ring on the front cover 801 and the rear cover 802 is equal to the number of steel wires distributed in a ring on the half cover of the fan cover 104. This design allows the steel wires on the anti-striking hand cover 8 and the steel wires on the fan cover 104 to remain opposite to each other, reducing the obstruction of airflow and thus reducing the impact on the normal blowing of the fan.

[0026] The anti-slap cover 8 and the fan cover 104 are tied together with wire. By tying them together, the anti-slap cover 8 is prevented from rotating relative to the fan cover 104 during use, thereby increasing the wind-blocking area and reducing the effectiveness of the fan.

[0027] The working principle of this utility model is as follows:

[0028] In use, first, fill the fan base 3 with counterweight material through the threaded hole 5 to increase the weight of the fan base 3. Then, install the threaded connector 4 at the bottom of the fan support rod 2 on the fan base 3 and seal the fan base 3. This can lower the overall center of gravity of the electric fan and improve its stability. Finally, install the front cover 801 and rear cover 802 of the anti-slap cover 8 on the outside of the fan cover 104 with screws 803 to prevent children from putting their hands into the fan cover 104 and being injured by the fan blades 103. Tie the anti-slap cover 8 to the fan cover 104 with cable ties to prevent the anti-slap cover 8 from rotating relative to the fan cover 104 and causing excessive wind resistance.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
