Description

Technical Field

[0001] This utility model relates to the field of office chair technology, and in particular to a multifunctional office chair that can be reclined for lunch breaks. Background Technology

[0002] An office chair is a type of seating specifically designed for office environments. It aims to provide comfort and support for people who sit for long periods of time. An office chair is more than just an ordinary seat; it integrates a variety of ergonomic designs and technologies to improve work efficiency, enhance comfort, and protect the user's health.

[0003] A multifunctional office chair is a type of seat that integrates multiple functions and design elements, designed to provide users with greater comfort, flexibility, and work efficiency. It not only has the basic features of a regular office chair, but also adds a variety of adjustment and auxiliary functions to meet the needs of different users.

[0004] The existing multi-functional office chair that allows for reclining during lunch breaks has the following shortcomings:

[0005] Existing reclining multi-functional office chairs, especially in summer when the weather is very hot and humid, can cause the parts of the body that come into contact with the chair, such as the back and buttocks, to generate heat and moisture due to prolonged contact. This can make people feel stuffy and seriously affect the comfort of the chair, making it easy to sweat during lunch breaks or while working. It may even make it difficult to fall asleep or concentrate on work due to the stuffiness.

[0006] Existing reclining multi-functional office chairs are frequently subjected to various external forces during daily use, such as collisions when moving the chair or impacts generated during rapid sliding, which can cause varying degrees of damage. Over time, this damage may lead to the collapse and deformation of the frame, potentially resulting in injury to the user and unnecessary economic losses. Utility Model Content

[0007] This utility model proposes a multi-functional office chair that allows users to lie down for a midday nap. By incorporating a ventilation device with a built-in fan, it promotes air circulation, quickly removes heat and moisture emitted by the body, and prevents users from sweating due to stuffiness.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: a multi-functional office chair for reclining during lunch breaks, characterized in that: it includes a seat surface, a support frame riveted to the bottom of the seat surface, a flexible metal connector fixedly connected to the outer wall of the support frame, a back cushion fitted and locked onto the outer wall of the flexible metal connector, a set of fixing members fixedly connected to the inner wall of the back cushion, a drive assembly fixedly installed between the outer walls of the set of fixing members, a fan blade inside the drive assembly, the fan blade being connected to the power end of the drive assembly, a first air guide pipe fixedly connected to the exhaust end of the drive assembly, and an air guide chamber fixedly installed on the rear side of the back cushion. The outer surface of the air chamber is provided with an air guide port. The first air guide pipe is connected to the air guide port. A set of third air guide holes are opened inside the air chamber. A set of first ventilation holes are opened inside the structure of the back pad. Each of the third air guide holes can communicate with a corresponding first ventilation hole. A second air guide pipe is fixedly connected to the bottom of the air chamber. The second air guide pipe is L-shaped. A second air chamber is fixedly connected to the outer wall of the second air guide pipe. The second air chamber is located inside the seat surface. A set of fourth air guide holes are opened at the top of the second air chamber. A set of second ventilation holes are opened inside the structure of the seat surface. Each of the fourth air guide holes can communicate with a corresponding second ventilation hole.

[0009] Preferably, a pneumatic rod is fixedly inserted inside the support frame, and a leg fixing component is fixedly sleeved on the outer wall of the pneumatic rod, and a set of five-star legs is fixedly inserted inside the leg fixing component.

[0010] Preferably, each of the five-star tripods is fixedly equipped with casters at its bottom.

[0011] Preferably, a tilt adjustment rod is fixedly inserted inside the support frame, and a first fixing rod and a second fixing rod are respectively inserted into the outer walls of the seat and the back pad.

[0012] Preferably, a retractable armrest is connected between the outer walls of each of the first and second fixing rods, and two lumbar pads are sewn to the outer wall of the back pad.

[0013] Preferably, the top of the back pad is sewn and covered with a headrest, and the bottom of each of the five-star legs is fixedly welded with reinforcing ribs.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. This utility model, by incorporating a built-in ventilation fan, can promote air circulation, quickly remove heat and moisture emitted by the human body, avoid sweating due to stuffiness, and improve the experience of working and taking a lunch break. Especially in summer, the hot and humid weather easily makes people sweat. With a built-in ventilation fan, this problem can be perfectly solved. By designing an outlet with a large hole inside a small hole, according to the Venturi effect, when the airflow enters the small hole from the large hole, the channel narrows and the flow rate increases. This accelerated airflow can more effectively penetrate the seat surface and provide a stronger ventilation effect.

[0016] 2. By setting a reinforcing rib, this utility model can prevent the seat pulley support frame from being damaged in daily collisions, ensure its rigidity, make it more resistant to such impact forces, reduce the possibility of the support frame being deformed or damaged due to external impacts, and increase the service life of the seat by setting a reinforcing rib. Even under long-term and frequent use, the reinforcing rib can make the pulley support frame maintain a relatively stable structure and strength. Attached Figure Description

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1, as shown in the attached document Figure 1 -Appendix Figure 6 As shown, this utility model provides a technical solution: including a seat surface 1, a support frame 2 riveted to the bottom of the seat surface 1, a flexible metal connector 6 fixedly connected to the outer wall of the support frame 2, a back pad 7 fitted and locked onto the outer wall of the flexible metal connector 6, a set of fixing members 16 fixedly connected to the inner wall of the back pad 7, a drive assembly 17 fixedly installed between the outer walls of the set of fixing members 16, a fan blade 18 provided inside the drive assembly 17, and the fan blade 18 connected to the power end of the drive assembly 17, a first air guide pipe 19 fixedly connected to the exhaust end of the drive assembly 17, an air guide chamber 21 fixedly installed on the rear side of the back pad 7, and an air guide port 20 provided on the outer surface of the air guide chamber 21. A duct 19 is connected to an air inlet 20. A set of third air guide holes 23 are provided inside the air guide chamber 21. A set of first ventilation holes 14 are provided inside the structure of the back pad 7. Each of the third air guide holes 23 can communicate with a corresponding first ventilation hole 14. A second air guide pipe 22 is fixedly connected to the bottom of the air guide chamber 21. The second air guide pipe 22 is L-shaped. A second air guide chamber 24 is fixedly connected to the outer wall of the second air guide pipe 22. The second air guide chamber 24 is located inside the seat surface 1. A set of fourth air guide holes 25 are provided at the top of the second air guide chamber 24. A set of second ventilation holes 15 are provided inside the structure of the seat surface 1. Each of the fourth air guide holes 25 can communicate with a corresponding second ventilation hole 15.

[0027] The effect achieved by the entire embodiment 1 is as follows: by pre-setting the above components, a complete seat ventilation system is formed. When the drive assembly 17 is turned on, under the action of pressure, the air will reach the third air guide hole 23 and the fourth air guide hole 25 of the seat surface 1 and the back cushion 7 respectively along the ventilation duct, and then pass to the first ventilation hole 14 and the second ventilation hole 15 respectively. On the one hand, according to the Venturi effect, when the airflow enters the small hole from the large hole, the channel narrows and the flow rate increases. On the other hand, according to Bernoulli's principle, the increase in airflow speed will lead to a decrease in air pressure. This pressure difference helps to distribute the air from the inside of the seat to the small hole more evenly, improve the ventilation uniformity, thereby promoting air circulation, quickly removing the heat and moisture emitted by the human body, avoiding sweating due to stuffiness, and improving the experience of working and taking a nap.

[0028] Example 2, as shown in the attached figure Figure 1 -Appendix Figure 6 As shown, this utility model provides a technical solution: a pneumatic rod 3 is fixedly inserted inside the support frame 2, a foot bracket is fixedly fitted on the outer wall of the pneumatic rod 3, and a set of five-star feet 4 is fixedly inserted inside the foot bracket. A pulley 5 is fixedly installed at the bottom of each set of five-star feet 4. A tilt adjustment rod 8 is fixedly inserted inside the support frame 2. A first fixing rod 9 and a second fixing rod 11 are respectively inserted into the outer walls of the seat 1 and the back cushion 7. A retractable armrest 10 is connected between the outer walls of each first fixing rod 9 and second fixing rod 11. Two lumbar pads 12 are sewn to the outer wall of the back cushion 7. A headrest 13 is sewn to the top of the back cushion 7. A reinforcing rib 26 is fixedly welded to the bottom of each set of five-star feet 4.

[0029] The effect achieved by the entire embodiment 2 is as follows: by pre-setting the above components, reinforcing ribs 26 are welded to the bottom of a set of five-star legs 4. The reinforcing ribs can improve the rigidity of the legs and prevent deformation or breakage caused by long-term use or overweight. On the one hand, the reinforcing ribs can effectively reduce the shaking of the seat during use, improve stability, and make the user more stable when moving the seat. On the other hand, the reinforcing ribs can help distribute some pressure, reduce local stress concentration, thereby improving the overall load-bearing capacity and extending the service life of the seat.

[0030] The working principle of the entire device is as follows: During the installation phase, the components to be assembled are first placed in a safe area to provide a safe assembly environment for subsequent assembly. First, a support frame 2 is riveted to the bottom of the seat 1, and a flexible metal connector 6 is fixedly connected to the outer wall of the support frame 2. A locking back pad 7 is then fitted onto the outer wall of the flexible metal connector 6. A set of fasteners 16 is fixedly connected to the inner wall of the back pad 7, and a drive assembly 17 is installed between the outer walls of the set of fasteners 16 using bolts. The drive assembly 17 has fan blades 18 inside. The fan blade 18 is connected to the power end of the drive assembly 17. The exhaust end of the drive assembly 17 is fixedly connected to the first air guide pipe 19, and an air guide chamber 21 is fixedly installed on the rear side of the back pad 7. An air guide port 20 is provided on the outer surface of the air guide chamber 21, and the first air guide pipe 19 is connected to the air guide port 20. A set of third air guide holes 23 are opened inside the air guide chamber 21. Because a set of first ventilation holes 14 are opened in the structure of the back pad 7, each third air guide hole 23 can communicate with a corresponding first ventilation hole 14. The bottom of the air guide chamber 21 is fixedly connected to... The second air duct 22 is L-shaped, and its outer wall is fixedly connected to the second air chamber 24. The second air chamber 24 is located inside the seat surface 1. A set of fourth air guide holes 25 are opened at the top of the second air chamber 24. A set of second ventilation holes 15 are opened in the structure of the seat surface 1, and each of the fourth air guide holes 25 can communicate with a corresponding second ventilation hole 15. Next, a pneumatic rod 3 is fixedly inserted inside the support frame 2, and a foot fixing component is fixedly sleeved on the outer wall of the pneumatic rod 3. A set of five-star brackets 4 are fixedly inserted inside the component, and pulleys 5 are fixedly installed at the bottom of each set of five-star brackets 4. An adjustable tilt rod 8 is fixedly inserted inside the support frame 2. A first fixed rod 9 and a second fixed rod 11 are respectively inserted into the outer walls of the seat 1 and the back cushion 7. A retractable armrest 10 is connected between the outer walls of each first fixed rod 9 and the second fixed rod 11. Two lumbar pads 12 are sewn to the outer wall of the back cushion 7. A headrest 13 is sewn to the top of the back cushion 7. A reinforcing rib 26 is fixedly welded to the bottom of the set of five-star brackets 4.

[0031] During the working phase, after all components are assembled, check whether each component is installed and fixed in place to ensure that it is not loose. Next, connect an external power source to provide energy for the ventilation device. First, turn on the drive assembly 17. After the motor starts, the output shaft drives the blade hub to rotate, and the blades rotate at a constant speed. When the fan starts running, the generated wind force drives the airflow. The initial airflow generated by the fan has a certain speed and pressure. At the pipe inlet, this force pushes the air into the pipe and transmits the wind force generated by the fan to the third air guide hole 23 and the fourth air guide hole 25 along the smooth inner wall of the pipe. Under the action of pressure, it flows to the first ventilation hole 14 and the second ventilation hole 15 in sequence. On the one hand, according to the Venturi effect, when the airflow enters the small hole from the large hole, the channel narrows and the flow velocity increases, thereby providing a stronger ventilation effect. On the other hand, according to Bernoulli's principle, the increase in airflow velocity will lead to a decrease in air pressure. This pressure difference helps to distribute air more evenly from inside the seat to the small holes, thereby improving the uniformity of ventilation. This ventilation device, designed with holes of different sizes, can quickly promote air circulation, quickly remove the user's own heat, avoid sweating due to stuffiness, and improve the experience of working and taking a lunch break.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
