Description

Technical Field

[0001] The utility model relates to the technical field of waist pads, in particular to a waist pad. Background Art

[0002] Lumbar cushion: It is a comfortable item for the waist, used to adjust the contact point between the human body and the seat to obtain a more comfortable angle to reduce fatigue. Lumbar cushion is easy to use and flexible, so it is convenient for people to use in various occasions. It is especially widely used on beds and chairs in bedrooms.

[0003] However, the waist pad in the prior art still has some defects:

[0004] Waist belts in the prior art generally have built-in suction and exhaust functions. When the waist cushion is fixed to a car seat or office chair, the suction port on the back will fit together with the seat, blocking the suction port. In this way, when the waist cushion starts the suction and exhaust function, the wind force will be very small, causing the wind coming out of the front air outlet to be very small and less, thereby affecting the ventilation and heat dissipation effect.

[0021] 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.

[0022] Example: Figure 1-4 As shown, the utility model provides a waist pad, which includes a waist pad front 10 and a waist pad back 20, and the waist pad back 20 is fixed to one side of the waist pad front 10;

[0023] The front side 10 of the lumbar pad is away from the side of the back side 20 of the lumbar pad. The air outlet 1 is set in three groups. Each group of air outlets 1 is designed as a honeycomb hole. By setting three groups of honeycomb hole-shaped air outlets 1, the wind blown out is more uniform, the air volume is more concentrated, and the ventilation and heat dissipation effect is improved. The back side 20 of the lumbar pad is away from the side of the front side 10 of the lumbar pad. A front air inlet 22 is set in the middle of the air guide plate 21. The front air inlet 22 is set in two groups. Each group of front air inlet 22 is composed of a number of holes with the same diameter. The two sides of the air guide plate 21 are Both are provided with side air inlets 23, a sealed cavity 30 is provided between the front face 10 and the back face 20 of the lumbar pad, two air ducts 24 are provided between the front face 10 and the back face 20 of the lumbar pad, one end of the two air ducts 24 is connected to the sealed cavity 30, and by providing an air guide plate 21 on the back face 20 of the lumbar pad, and providing a front air inlet 22 and a side air inlet 23 on the air guide plate 21, when the back face 20 of the lumbar pad is attached to the seat, even if the front air inlet 22 cannot suck in air, wind can enter the sealed cavity 30 from the side air inlets 23 on both sides of the air guide plate 21;

[0024] The first fan 31 and the second fan 32 are fixedly installed inside the sealed cavity 30. By setting the first fan 31 and the second fan 32, the first fan 31 sucks the air in the sealed cavity 30, and then blows it through the second fan 32. The wind then runs in the air duct 24, and then blows out from the three groups of air outlets 1 on the front side 10 of the lumbar pad and blows to the back of the human body, thereby achieving the effect of ventilation and heat dissipation.

[0025] A fixing clip 40 is provided at the bottom of the back side 20 of the lumbar pad. By providing the fixing clip 40 , the front side 10 and the back side 20 of the lumbar pad can be fixed to a car seat or an office chair through the fixing clip 40 .

[0026] Working principle: When in use, first fix it to the seat with the fixing clip 40, and the back of the lumbar pad 20 is attached to the seat. The air flows into the sealed cavity 30 through the front air inlet 22 and the two side air inlets 23;

[0027] At the same time, the first fan 31 and the second fan 32 are started respectively. The first fan 31 sucks the airflow in the sealed cavity 30, and the second fan 32 blows the airflow. The airflow runs in the air duct 24, and then the airflow is blown out from the three groups of air outlets 1 on the front side 10 of the lumbar pad and blows to the back of the human body, thereby achieving the effect of ventilation and heat dissipation, avoiding the airflow being unable to enter or the airflow entering being low due to the back side 20 of the lumbar pad being attached to the seat, and at the same time avoiding the wind blowing out from the front side 10 of the lumbar pad being small, thereby improving the effect of ventilation and heat dissipation.

[0028] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
