Description

Technical Field

[0001] The utility model belongs to the technical field of helmets, and particularly relates to a helmet with a refrigeration function. Background Art

[0002] A cycling helmet covers the driver's head entirely, making it slow for the driver to sweat and dissipate heat, so an additional fan is needed for refrigeration. In addition to the fan, the application of thermoelectric coolers has become increasingly widespread, especially when paired with a positive and negative conversion switch to reverse the direction of the current so that the inner side of the thermoelectric cooler can switch between the refrigeration state and the heating state.

[0003] Since the combined power consumption of the thermoelectric cooler and the fan is relatively large, the battery life of the battery is significantly shortened, and increasing the number of batteries will significantly increase the weight of the helmet. In this case, it is necessary to add a solar panel to the helmet to continuously supply power to the battery through solar energy.

[0004] When the helmet dissipates heat internally, aluminum or copper heat sinks are used to assist in heat conduction, transferring the heat to the airflow blown by the fan. However, the area where the head is covered by the helmet often sweats, and the blowing area of the fan is limited, making it difficult to cover the entire head. Moreover, the aluminum or copper heat sinks are difficult to absorb sweat, so it is not convenient to balance refrigeration and rapid sweating. Therefore, we propose a helmet with a refrigeration function. Summary of the Invention

[0005] The purpose of the utility model is to provide a helmet with a refrigeration function, which can absorb the sweat on the head in a large area, and then agitate the airflow to take away the moisture for rapid sweating, facilitating the balance between refrigeration and rapid sweating.

[0006] The technical solution adopted by the utility model is specifically as follows:

[0007] A helmet with a refrigeration function includes a helmet body and a fan fixedly connected to the back of the helmet body. A plurality of strip-shaped holes are equidistantly formed in the upper wall of the helmet body. An absorbent cloth piece is adhered to the upper surface of the helmet body. Curved portions are fixedly arranged on the absorbent cloth piece at equal intervals. The curved portions all pass downward through adjacent strip-shaped holes and protrude in a tubular shape. Silicone edge guards are sleeved on both sides of the tubular protrusion of the curved portion. The silicone edge guards all have a curvature. One side of each silicone edge guard is fixedly connected to the inner edge of the adjacent strip-shaped hole. When worn, the absorbent cloth piece, the curved portions, and the silicone edge guards form a lining for protecting the head. Moreover, the curved portions can absorb the sweat on the head in a large area and transfer it to the absorbent cloth piece. After the fan is started, the airflow can be agitated to take away the moisture on the absorbent cloth piece for rapid sweating. Additionally, the airflow agitated by the fan can enter the interior of the helmet body along the strip-shaped holes to reduce the head temperature, facilitating the balance between refrigeration and rapid sweating.

[0008] A deflector is provided above the helmet body. Both sides of the deflector respectively extend beyond the two ends of the strip-shaped holes and are fixedly connected to the upper surface of the helmet body. The back surface of the deflector faces the fan. By using the deflector to limit the airflow blown out by the fan, the airflow is concentrated at the strip-shaped holes.

[0009] A wind collecting hopper with a hollow structure is fixed to the outer edge of the deflector. The air inlet of the wind collecting hopper is communicated with the air outlet of the fan. The airflow blown out by the fan diffuses through the wind collecting hopper and rushes into all the spaces inside the deflector as much as possible.

[0010] A dust-proof mesh cloth is fixed to the air inlet of the fan to filter the dust in the airflow and reduce the dust entering the helmet body along the strip-shaped holes.

[0011] The deflector surrounds all the strip-shaped holes. There is a gap between the deflector and the front edge of the helmet body as the moving space for the goggles. And the deflector covers all the strip-shaped holes so that all the strip-shaped holes can have airflow rushing in, avoiding waste.

[0012] A sealing rubber plug is inserted into the front surface of the deflector. In rainy weather or other such weather conditions, the air inlet of the deflector can be blocked with the sealing rubber plug to facilitate the strip-shaped holes to be in a closed environment and reduce water seepage.

[0013] The technical effects achieved by the present utility model are as follows:

[0014] For the helmet with a refrigeration function of the present utility model, when worn, the inner lining is composed of a water-absorbing cloth piece, a bending part and a silica gel edge guard, which is used to protect the head. Moreover, the bending part can absorb the sweat on the head in a large area and transfer it to the water-absorbing cloth piece. In this way, after the fan is started, the airflow can be agitated to take away the moisture on the water-absorbing cloth piece for rapid sweating; and, the airflow agitated by the fan can enter the helmet body along the strip-shaped holes to reduce the head temperature, so as to give consideration to both refrigeration and rapid sweating.

[0022] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.

[0023] As Figures 1-5 shown, a helmet with a refrigeration function includes a helmet body 1 and a fan 2 fixedly connected to the back of the helmet body 1. The helmet body 1 is equipped with accessories such as goggles and a neck guard. A lithium battery pack for powering the fan 2, as well as supporting wires and a switch button, are fixed on the helmet body 1;

[0024] A plurality of striped holes 3 are equidistantly opened on the upper wall of the helmet body 1. A water-absorbing cloth piece 4 is bonded to the upper surface of the helmet body 1. The water-absorbing cloth piece 4 can be made of polyacrylic acid-based superabsorbent fiber material. Bending parts 5 are fixedly arranged on the water-absorbing cloth piece 4 at equal intervals. The bending parts 5 and the water-absorbing cloth piece 4 are integrally formed. The bending parts 5 all pass downward through adjacent striped holes 3 and protrude in a tubular shape. Silicone edge guards 6 are sleeved on both sides of the tubular protrusion of the bending part 5. The silicone edge guards 6 can be made of medical-grade silicone material. The silicone edge guards 6 all have a curvature. One side of each silicone edge guard 6 is fixedly connected to the inner edge of the adjacent striped hole 3. When worn, the inner lining is composed of the water-absorbing cloth piece 4, the bending part 5 and the silicone edge guard 6, which is used to protect the head. Moreover, the bending part 5 can absorb the sweat on the head in a large area and transfer it to the water-absorbing cloth piece 4. In this way, after starting the fan 2, the airflow can be agitated to take away the moisture on the water-absorbing cloth piece 4 for rapid sweating;

[0025] And, the airflow agitated by the fan 2 can enter the interior of the helmet body 1 along the striped holes 3 to reduce the head temperature, facilitating both refrigeration and rapid sweating.

[0026] Among them, referring to the Chinese utility model "A Refrigerating, Heating and Defogging Air-Conditioned Helmet" with the publication number CN218245858U, a semiconductor refrigeration sheet, a copper heat-conducting sheet or an aluminum heat-conducting sheet can be installed inside the helmet body 1, which can perform heat exchange after being started to accelerate the heat dissipation inside the helmet body 1.

[0027] As Figure 1 . Figure 3 And Figure 4As shown in the figure, a deflector 7 is provided above the helmet body 1. The deflector 7 can be made of acrylic material, which has good structural strength and the color can be DIY customized. The two sides of the deflector 7 respectively cross the two ends of the strip-shaped hole 3 and are fixedly connected to the upper surface of the helmet body 1. The back of the deflector 7 faces the fan 2. The deflector 7 is used to limit the airflow blown out by the fan 2 and concentrate it at the strip-shaped hole 3. It can also block rain and sunlight, preventing rain from falling into the strip-shaped hole 3.

[0028] As Figure 1 、 Figure 3 and Figure 4 shown, a wind collecting hopper 8 with a hollow structure is fixed to the outer edge of the deflector 7. The wind collecting hopper 8 and the deflector 7 are integrally formed. The air inlet of the wind collecting hopper 8 is communicated with the air outlet of the fan 2. The airflow blown out by the fan 2 diffuses through the wind collecting hopper 8 and rushes into all the spaces inside the deflector 7 as much as possible.

[0029] As Figure 1 、 Figure 3 and Figure 4 shown, a dust-proof mesh cloth 9 is fixed to the air inlet of the fan 2 to filter the dust in the airflow and reduce the dust entering the inside of the helmet body 1 along the strip-shaped hole 3.

[0030] As Figure 1 、 Figure 2 and Figure 3 shown, the deflector 7 surrounds all the strip-shaped holes 3. There is a gap between the deflector 7 and the front edge of the helmet body 1 as the moving space for the goggles. And the deflector 7 covers all the strip-shaped holes 3, so that all the strip-shaped holes 3 can have airflow rushing in, avoiding waste.

[0031] As Figure 1 and Figure 5 shown, a sealing rubber plug 10 is inserted into the front of the deflector 7. The sealing rubber plug 10 can be made of fluororubber material, which has good high-temperature resistance and anti-aging properties. In rainy weather, etc., the sealing rubber plug 10 can be used to block the air inlet of the deflector 7, facilitating the strip-shaped hole 3 to be in a closed environment and reducing water seepage.

[0032] The working principle of the present utility model is as follows: When wearing, the inner lining composed of the water-absorbing cloth piece 4, the bending part 5 and the silica gel edge 6 is used to protect the head. Moreover, the bending part 5 can absorb the sweat on the head in a large area and transfer it to the water-absorbing cloth piece 4. After starting the fan 2, the airflow can be agitated to take away the moisture on the water-absorbing cloth piece 4 for rapid sweating;

[0033] And, the airflow agitated by the fan 2 can enter the inside of the helmet body 1 along the strip-shaped hole 3, which is used to reduce the head temperature and is convenient for both cooling and rapid sweating.

[0034] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
