Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Referring to Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present invention: a foldable portable office chair, including two rear columns 1 and two front columns 3. A cross beam rod 4 is fixedly connected to the bottom ends between the adjacent two rear columns 1 and between the adjacent two front columns 3. Short rotating shafts 5 are fixedly connected to the upper and lower ends of the far sides of the two rear columns 1 and the far sides of the two front columns 3. Long rotating shafts 6 are fixedly connected to the bottom ends of the far sides of the two rear columns 1. Moving rods 7 are rotatably connected to the outer walls of the upper and lower short rotating shafts 5 on the left and right sides of the top ends and the outer walls of the two short rotating shafts 5 at the bottom ends and the two long rotating shafts 6. Storage grooves 8 are provided at the bottom ends on the left sides of the two rear columns 1. Fixed rods 9 are provided inside the two storage grooves 8. The two long rotating shafts 6 penetrate through the bottoms of the storage grooves 8. The bottom parts of the two fixed rods 9 are respectively rotatably connected to the middle parts of the outer walls of the two long rotating shafts 6. Fixed grooves 10 are provided on the right sides of the two front columns 3. The top parts of the two fixed rods 9 are respectively clamped in the inner walls of the two fixed grooves 10. A seat cushion 11 is rotatably connected between the middle parts of the two rear columns 1 and the tops of the two front columns 3. A seat ventilation mechanism 2 is provided inside the seat cushion 11;

[0033] Specifically, when in the unfolded state, the two rear columns 1 and the two front columns 3 are connected by the cross beam rod 4, playing a role of stable support. The short rotating shafts 5 and the long rotating shafts 6 on the far sides of the rear columns 1 and the front columns 3 are connected with the moving rods 7. The moving rods 7 can rotate around the rotating shafts and can provide a certain supporting force during use. The seat cushion 11 rotatably connected between the rear columns 1 and the front columns 3 provides a seating position for the user. When folding is required, the fixed rods 9 are taken out from the fixed grooves 10. The bottom parts of the fixed rods 9 are rotatably connected to the long rotating shafts 6 in the storage grooves 8 at the bottom ends on the left sides of the rear columns 1. Through the rotation of the long rotating shafts 6, the fixed rods 9 can be retracted into the storage grooves 8. Then, the moving rods 7 are rotated around the connection points between the rear columns 1 and the front columns 3 and the short rotating shafts 5 and the long rotating shafts 6 to make them fit with the columns. Finally, the seat cushion 11 is rotated to a position parallel to the columns to complete the folding, making the entire folding process simple to operate, convenient to carry, occupying a small space, and suitable for use in occasions where portable office is required.

[0034] Referring to Figure 1 , Figure 4 and Figure 5, the seat ventilation mechanism 2 includes a built-in power supply 201. Air inlets 202 are opened at the left and right ends of the rear side of the seat cushion 11. Inner walls of the two air inlets 202 are fixedly connected with fans 203. A plurality of air outlet holes 204 are equidistantly opened at the top of the seat cushion 11. The plurality of air outlet holes 204 are all communicated with the air inlets 202. The middle part of the left side of the seat cushion 11 is fixedly connected with an adjustment panel 205. A plurality of gear adjustment buttons 206 are fixedly connected to the left side of the adjustment panel 205 at equal intervals;

[0035] Specifically, the built-in power supply 201 provides power for the entire ventilation system. When the ventilation function is needed, the fans 203 are started. Air is sucked in from the air inlets 202 at the left and right ends of the rear side of the seat cushion 11. The fans 203 operate to generate airflows. The airflows enter the channels inside the seat cushion 11 through the air inlets 202. Since the plurality of air outlet holes 204 are all communicated with the air inlets 202, the airflows are blown out from the air outlet holes 204, forming an air flow at the contact part between the user and the seat cushion 11, so as to achieve the effect of ventilation and heat dissipation. The plurality of gear adjustment buttons 206 on the left side of the adjustment panel 205 can control the rotation speed of the fans 203. By pressing different gear adjustment buttons 206, the built-in power supply 201 delivers currents with different intensities to the fans 203, thereby changing the rotation speed of the fans 203 and realizing ventilation effects of different degrees to meet the use of the user in different environments and requirements.

[0036] Refer to Figure 1 , on the upper middle parts of the adjacent sides of the two front columns 3, rotating rods 12 are fixedly connected. At the bottom ends of the two rotating rods 12, annular buckles 13 are fixedly connected. On the upper middle parts of the adjacent sides of the two rear columns 1, fixed buckles 14 are fixedly connected. The two annular buckles 13 are respectively clamped on the outer walls of the two fixed buckles 14; On the upper middle parts of the right sides of the two rear columns 1, a plurality of backrest reinforcing ribs 15 are fixedly connected. The middle parts of the plurality of backrest reinforcing ribs 15 are all provided with arcs backward; At the top ends between the two adjacent rear columns 1, headrests 16 are fixedly connected. Side pillows 17 are fixedly connected to the front ends of the left and right sides of the headrest 16;

[0037] Specifically, when the annular buckles 13 are clamped on the outer walls of the fixed buckles 14, the connection stability between the front columns 3 and the rear columns 1 can be enhanced, preventing the chair from accidentally unfolding during folding. On the one hand, the backrest reinforcing ribs 15 can enhance the structural strength of the rear columns 1, improving the overall stability and durability of the chair. On the other hand, the arc design with the middle part backward can better fit the curve of the human back, providing comfortable support for the user and reducing back fatigue. The headrests 16 can provide support for the user's head, reducing neck pressure. The side pillows 17 further enhance the wrapping feeling and comfort of the head. At the same time, when the user is resting or relaxing, they can prevent the head from tilting too much to both sides and maintain a good sitting posture.

[0038] Refer to Figure 1 and Figure 5, rubber bases 18 are fixedly connected to the bottoms of the two rear columns 1 and the two front columns 3, and the bottoms of the multiple rubber bases 18 are all treated with anti-slip; a charging hole 19 is provided in the middle of the rear side of the seat cushion 11, and the charging hole 19 is electrically connected to the built-in power supply 201; a plurality of power indicators 20 are fixedly connected to the lower middle part of the rear side of the seat cushion 11, and the plurality of power indicators 20 are all electrically connected to the built-in power supply 201;

[0039] Specifically, the rubber base 18 can play an anti-slip role, increasing the friction between the chair and the ground, ensuring that the chair will not slide easily during use, improving safety. The rubber material has a certain buffering effect, which can reduce the vibration generated when the chair moves or is subjected to external forces. The charging hole 19 provides a charging interface for the built-in power supply 201, facilitating the user to charge the built-in power supply 201 of the seat ventilation mechanism 2 when needed, ensuring the continuous use of the ventilation function, and improving the convenience and practicality of the chair. The power indicator 20 can intuitively display the power status of the built-in power supply 201. The user can understand the remaining power of the power supply by observing the power indicator 20, so as to charge in time and avoid affecting the normal use of functions such as ventilation due to insufficient power during use.

[0040] Working principle: When in the unfolded state, the two rear columns 1 and the two front columns 3 are connected by the cross beam rod 4, playing a role of stable support. The short rotating shafts 5 and the long rotating shafts 6 on the sides of the rear column 1 and the front column 3 away from each other are connected with the moving rods 7, and the moving rods 7 can rotate around the rotating shafts, providing a certain supporting force during use. The seat cushion 11 rotatably connected between the rear column 1 and the front column 3 provides a seating position for the user. When folding is required, the fixing rod 9 is taken out from the fixing groove 10. The bottom of the fixing rod 9 is rotatably connected to the long rotating shaft 6 in the storage groove 8 at the left bottom end of the rear column 1. By rotating the long rotating shaft 6, the fixing rod 9 can be retracted into the storage groove 8. Then, the moving rod 7 is rotated around the connection point between the rear column 1 and the front column 3 and the short rotating shaft 5 and the long rotating shaft 6 to make it fit with the column. Finally, the seat cushion 11 is rotated to a position parallel to the column to complete the folding;

[0041] Moreover, the built-in power supply 201 provides power for the entire ventilation system. When the ventilation function needs to be used, the fan 203 is started, and air is sucked in from the air inlets 202 at the left and right ends of the rear side of the seat cushion 11. The fan 203 operates to generate an air flow, and the air flow enters the channels inside the seat cushion 11 through the air inlets 202. Since the multiple air outlet holes 204 are all interconnected with the air inlets 202, the air flow blows out from the air outlet holes 204, forming an air flow at the contact part between the user and the seat cushion 11, so as to achieve the effect of ventilation and heat dissipation. The multiple gear adjustment buttons 206 on the left side of the adjustment panel 205 can control the rotation speed of the fan 203. By pressing different gear adjustment buttons 206, the built-in power supply 201 delivers currents of different intensities to the fan 203, thereby changing the rotation speed of the fan 203.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
