[0030] 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.

[0031] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0032] Embodiment 1:

[0033] See also Figure 1-Figure 5 A lumbar support with a blowing function comprises a main body 1, the main body 1 comprises a lumbar support 11 and a blowing assembly 12 embedded in the lumbar support 11. In the present embodiment, the blowing assembly 12 is arranged on the back of the lumbar support 11 and close to the bottom of the lumbar support 11. The front of the lumbar support 11 contacts the back of the human body during use, and the back of the lumbar support 11 contacts the back of a car seat or a backrest chair to form support for the waist or back of the human body. A plurality of groups of air outlet holes 10 are provided on the lumbar support 11, and the plurality of groups of air outlet holes 10 are located in the middle of the lumbar support 11. The air outlet holes 10 are connected with the air outlet holes on the blowing assembly 12. The blowing assembly 12 comprises at least one group of fans 121. The cold air formed after the fans 121 are started is blown out from the air outlet holes 10, so that the lumbar support 11 has the effect of blowing and dissipating heat.

[0034] See also Figure 1-5 The blowing assembly 12 also includes a bottom shell 122, the air outlet holes on the blowing assembly 12 are opened on the bottom shell 122, and the air outlet holes are arranged one by one with the air outlet holes 10. The fan 121 includes a motor 20 and a fan blade 30 installed on the rotating shaft of the motor 20. The bottom shell 122 is provided with a cover plate 123, and the cover plate 123 is fixedly connected to the top of the bottom shell 122. The blowing assembly 12 also includes at least one set of air inlets 124, and the air inlet 124 is used to introduce cold air. A wind cavity 4 is provided between the cover plate 123 and the bottom shell 122. 0, the air outlet hole 10 is connected with the air cavity 40 through the air outlet hole, a fan installation cavity 401 is provided on one side of the air cavity 40, the air duct of the fan installation cavity 401 is connected with the air cavity 40, the fan 121 is fixedly installed in the fan installation cavity 401, and the air inlet 124 is provided on the cover plate 123. In this embodiment, there is a cavity with a certain depth and sealing effect between the cover plate 123 and the bottom shell 122, wherein the air cavity 40 and the fan installation cavity 401 are both located in the cavity, and the fan installation cavity 401 is connected with the air cavity 40;

[0035] In this way, when the fan 121 is started, the motor 20 drives the fan blades 30 to rotate. While the fan blades 30 rotate, the cold air outside the main body 1 is quickly introduced into the wind cavity 40 through the air inlet 124, and finally discharged from the front of the lumbar support 11 outside the air outlet hole 10, and blown toward the back of the human body, thereby achieving the ventilation and heat dissipation effect of the lumbar support 11.

[0036] Example 2: Please refer to Figure 6-7 This embodiment is an improvement on the embodiment 1. The improvement is that the air inlet 124 is opened on the bottom shell 122, and the air inlet 124 extends outward to penetrate the lumbar support 11 at the corresponding position. In this embodiment, the air inlet 124 is opened at the bottom of the bottom shell 122 and is located below the fan installation cavity 401;

[0037] In this way, when the fan 121 is started, the motor 20 drives the fan blades 30 to rotate. While the fan blades 30 rotate, the cold air outside the main body 1 is quickly introduced into the air cavity 40 through the air inlet 124, and finally discharged from the front of the waist support 11 outside the air outlet hole 10 and blown toward the back of the human body, thereby achieving the ventilation and heat dissipation effect of the waist support 11;

[0038] In other embodiments, the air inlet 124 may also be provided on the left or right side of the fan installation cavity 401 or on either side thereof, so as to select the best air intake effect.

[0039] Working principle: The air outlet structures of the first and second embodiments of the utility model patent are the same, and the blowing assembly 12 is provided with a power cord plug-in terminal, wherein the motor 20 is electrically connected to the power cord plug-in terminal, and is powered by an external power supply or a vehicle-mounted power supply. When the blowing assembly 12 is powered on, the motor 20 rotates, and the rotating shaft of the motor 20 is linked to the fan blades 30 to rotate. When the fan blades 30 rotate, the external cold air is quickly introduced into the wind cavity 40, forming cold wind with a certain speed, and the cold wind is blown toward the back of the human body along the air outlet hole 10, which has a good ventilation and heat dissipation effect and is very practical.

[0040] When in use, the main body 1 only needs to be placed or fixed on the back of a seat or chair in a vertical direction, with the air outlet hole 10 facing the back of the human body, and the power cord plug end is plugged into an external power source, and the installation is very convenient.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
