DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] See Figures 1 to 3 As shown, an office chair with a back ventilation assembly includes a chair leg 1, a seat 2 fixed on the chair leg and a backrest 3 arranged at the edge of the seat, and a ventilation assembly 4 is arranged in the backrest; in this embodiment, the chair leg, seat and backrest are all conventional structures of the prior art and are simply applied.

[0025] In actual application, a headrest 5 and a waist pad 6 are arranged on the front of the backrest; the headrest and the waist pad are fixedly arranged on the backrest, and ventilation holes 7 are arranged on the top and bottom edges of the headrest and the waist pad; air can be blown downward and upward through the ventilation holes, and will not be blown directly to the human body, which can improve the comfort of use.

[0026] And in the actual application process, the ventilation assembly includes a fan 41, a ventilation tube body 42 and a water cooling bag 43; the ventilation tube body is a copper tube body or an aluminum tube body. The ventilation tube body is an S-shaped tube body. The contact area with the water cooling bag can be increased to improve the cooling effect. At the same time, a cavity 8 is provided in the backrest. During installation, the fan is fixed in the cavity, the ventilation tube body is provided between the air outlet end of the fan and the ventilation pores, the water cooling bag is coated on the outside of the ventilation tube body, and the water cooling bag is filled with coolant. The airflow in the ventilation tube body will pass through the water cooling bag for cooling, so that the blown airflow is slightly lower than the ambient temperature, which is conducive to improving the cooling effect and has strong practicality.

[0027] Meanwhile, in actual application, a mesh plate 9 is provided on the back of the backrest, and a trumpet-shaped air duct 10 is provided in the cavity; during installation, the mesh plate is located at the large-diameter end of the trumpet-shaped air duct, and the fan is fixed at the small-diameter end of the trumpet-shaped air duct. The trumpet-shaped air duct can be used to blow air, improve the blowing effect, and prevent blockage.
