Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to a mesh chair. Background Art

[0002] Mesh chairs refer to various chairs with mesh structures that are equipped for the convenience of work in daily work and social activities. Using mesh chairs can save costs, increase breathability, and avoid heat accumulation during long-term use in summer, which causes stuffy discomfort.

[0003] There are some mesh chairs in the prior art, such as the utility model patent document with authorization announcement number "CN212729290U" and patent name "An Anti-static Middle-class Fabric Mesh Chair", which discloses a mesh chair including an anti-static layer, mesh cloth, a top coating, a base fabric layer and an opening zipper.

[0004] When using this mesh chair, the antistatic layer reduces the mesh's ability to absorb static electricity from suspended particles and clothing fibers. A topcoat acts as a protective layer on the base fabric. By pulling the zipper's slider against the locking element and releasing it, the zipper's chain can be detached, allowing the mesh to be cleaned and replaced. However, for comfort and other functional features, some existing mesh chairs incorporate functional layers made of sponge cushions and other fabrics. This makes it difficult to dissipate heat during extended use in hot weather, resulting in poor air and moisture permeability. Utility Model Content

[0005] The purpose of this utility model is to address the deficiencies of the existing technology and to propose a mesh chair to solve the technical problem mentioned in the background technology that some existing mesh chairs are added with functional layers composed of sponge cushions and some other fabrics for the sake of comfort and other functions, so that when the weather is relatively hot, it is difficult for users to dissipate heat for a long time and the air permeability and moisture permeability are poor.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A mesh chair comprises a seat plate and support legs fixed to the bottom of the seat plate, a seat cushion formed of a breathable mesh cloth is installed on the top of the seat plate, an air outlet sponge layer composed of a porous sponge is provided on both sides of the seat cushion, a bamboo charcoal fiber sterilization layer composed of a porous sponge, a memory sponge layer, a first mounting plate and a second mounting plate of a mesh plate structure are arranged in sequence from top to bottom between the two air outlet sponge layers and in the seat cushion, a plurality of telescopic rods are fixed between the first mounting plate and the second mounting plate, and a vertical spring is wound around each telescopic rod The top end of the spring is fixed to the bottom of the first mounting plate, the bottom end of the spring is fixed to the top of the second mounting plate, an exhaust assembly is provided at the bottom of the seat plate, and the exhaust assembly is used to draw external air into the seat cushion, a positioning plate is glued to the bottom of the seat cushion with glue, and a plurality of air inlet holes are provided on the positioning plate that abut the bottom of the seat cushion, a mounting groove is provided on the top of the seat plate, and the positioning plate is arranged in the mounting groove, and a first bolt is screwed into the bottom thread of the seat plate, and the first bolt thread passes through the seat plate and is threadedly connected to the positioning plate.

[0008] Working principle:

[0009] When the user sits on the seat cushion and applies pressure to it, the seat cushion vertically presses down the first mounting plate through the bamboo charcoal fiber sterilization layer and the memory foam layer. The first mounting plate elastically buffers through the telescopic rod and the spring, and at the same time presses down the second mounting plate. At this time, the air in the seat cushion is squeezed out of the seat cushion through the air outlet sponge layer.

[0010] When the user needs to cool down after using the seat for a long time, the exhaust component is first started. The exhaust component draws the air under the seat plate into the mounting groove, and then enters the seat cushion through multiple air inlet holes on the positioning plate. After that, the air in the seat cushion moves upward through the first mounting plate and the second mounting plate of the grid plate structure, and finally overflows from the top of the seat cushion through the memory foam layer and the bamboo charcoal fiber sterilization layer, thereby cooling the user.

[0011] When the user needs to replace the seat cushion, the user rotates the first bolt to separate it from the positioning plate and screw it out of the seat plate.

[0012] The beneficial effects of the utility model are:

[0013] During the use of the utility model, the operator causes the working exhaust component to draw air into the seat cushion, and causes the air in the seat cushion to pass upward through the second mounting plate, the first mounting plate, the memory foam layer and the bamboo charcoal fiber sterilization layer in sequence, thereby cooling down the user who sits on the seat cushion for a long time, avoiding the problem that some mesh chairs, for the sake of comfort and other functions, add functional layers composed of sponge cushions and some other fabrics, which makes it difficult for users to dissipate heat and have poor air permeability and moisture permeability when used for a long time in hot weather.

At the same time, the air in the first air outlet 17 cools the user's back through the air induction component. This design method realizes the circulation of air in the seat cushion 3, avoids the heat from gathering in one place when the user sits on the seat cushion 3, is easy to dissipate heat, and has good air permeability and moisture permeability; at the same time, the air entering the seat cushion 3 is filtered through the dust filter 19 to prevent dust and other impurities from entering the seat cushion 3 and causing pollution and reducing its service life; at the same time, it can cool the user's back, has a simple structure and good effect.

[0024] like Figure 1 、 Figure 4 and Figure 5 As shown, the bottom outer tube opening of the first air inlet pipe 18 is fixed with an annular first positioning ring 31, and also includes a second air inlet pipe 32. One of the outer tube openings of the second air inlet pipe 32 is fixed with an annular second positioning ring 33. The second positioning ring 33 abuts the bottom surface of the first positioning ring 31, and the dust filter 19 is arranged between the two. A second bolt 34 is threaded through the second positioning ring 33. The second bolt 34 is threaded through the dust filter 19 and is threadedly connected to the first positioning ring 31. When the dust filter 19 needs to be replaced, the user unscrews the second bolt 34 and separates it from the first positioning ring 31 and the second positioning ring 33 respectively. Then, a new dust filter 19 is attached to the bottom surface of the first positioning ring 31, and then the top surface of the second positioning ring 33 is attached to the bottom surface of the dust filter 19. At this time, the user screws in the second bolt 34 and threads it through the second positioning ring 33, and the dust filter 19 is threadedly connected to the first positioning ring 31. This design is simple to operate and convenient for replacing the dust filter 19 .

[0025] like Figure 1 、 Figure 4 and Figure 5As shown, a hollow back plate 20 is fixedly provided on one side of the top of the seat plate 1, and an air outlet cavity 21 is provided inside the back plate 20. An armrest 22 fixed to the seat plate 1 is provided on both sides of the back plate 20. The air induction component includes a placement groove 23, an air pump 24 and a third air outlet pipe 25 provided inside one end of the seat plate 1. The placement groove 23 is located below the back plate 20. The inner wall of the placement groove 23 is provided with a shock-absorbing cushion 26. The air pump 24 is provided in the placement groove 23, and the first air outlet pipe 17 is connected to a second air outlet pipe 27 passing through the positioning member 15. The second air outlet pipe 27 passes through the seat plate 1 and the shock-absorbing cushion 26 and is fixedly connected to the air extraction end of the air pump 24. One end of the third air outlet pipe 25 is located in the air outlet cavity 21. The third air outlet pipe 25 passes through the back plate 20, the seat plate 1 and the shock-absorbing cushion 26 and is fixedly connected to the air outlet end of the air pump 24. A plurality of third air outlet holes are provided on the third air outlet pipe 25. An opening that is connected to the air outlet cavity 21 is provided on one side of the back plate 20 for leaning on. A mounting frame 29 of matching size is fixedly provided at the opening, and a mesh cloth 30 is provided inside the mounting frame 29. When the silent fan 16 is working, the user starts the air pump 24. At this time, the shock-absorbing cushion 26 reduces the vibration of the working air pump 24 and pumps the air in the first air outlet pipe 17 into the third air outlet pipe 25 through the second air outlet pipe 27. Then, the air is discharged to the air outlet cavity 21 through the first air outlet hole 28 on the third air outlet pipe 25, and then discharged to the back plate 20 through the mesh cloth 30, thereby cooling the user's back. This design method cools the user's back, legs and buttocks sitting on the seat cushion 3 at the same time. It has a simple structure and good effect. At the same time, the cooperation of the third air outlet pipe 25, the first air outlet hole 28 and the mesh cloth 30 facilitates the circulation of air in the back plate 20. The shock-absorbing cushion 26 also reduces the vibration of the working air pump 24 to avoid affecting the user's daily work.

[0026] like Figure 1 and Figure 5 As shown, the placement slot 23 has an opening at one end of the seat plate 1. A dust block 35 is secured to the opening, and sound insulation cotton 36 is positioned within the dust block 35. When the dust block 35 is engaged with the seat plate 1, the sound insulation cotton 36 is positioned within the placement slot 23. After activating the vacuum pump 24, the user engages the dust block 35 with the opening of the placement slot 23, at which point the sound insulation cotton 36 is positioned within the placement slot 23. This design facilitates covering the placement slot 23, preventing dust and other impurities from entering the placement slot 23 and enabling the vacuum pump 24 to operate smoothly. Furthermore, the sound insulation cotton 36 absorbs noise, preventing excessive noise from disrupting the user's work.

[0027] like Figure 1 and Figure 2As shown, the top of the seat cushion 3 is provided with an openable and closable wear-resistant layer 37, which is provided with a plurality of massage protrusions 38 and a second air outlet 39. A Velcro surface 40 is fixedly provided on one side of the opening of the wear-resistant layer 37. A Velcro adhesive surface 41 is fixedly provided between the seat cushion 3 and the opening of the wear-resistant layer 37, located below the Velcro surface 40. The bamboo charcoal fiber sterilization layer 5, the memory foam layer 6, the first mounting plate 7, and the second mounting plate 8 are all located below the wear-resistant layer 37. When a user sits on the wear-resistant layer 37, the user's legs and buttocks come into contact with the plurality of massage protrusions 38, and the air in the seat cushion 3 also flows out of the seat cushion 3 through the first air outlet 28 on the wear-resistant layer 37, cooling the user. When the bamboo charcoal fiber sterilization layer 5 needs to be cleaned or replaced, the user tears off the Velcro surface 40 to separate it from the Velcro adhesive surface 41, thereby separating the wear-resistant layer 37 from the seat cushion 3, and then removes the bamboo charcoal fiber sterilization layer 5 from the leather cover. This design facilitates positioning and disassembly between the wear-resistant layer 37 and the seat cushion 3, and the positioning method is simple and easy to operate.

[0028] Working principle:

[0029] When a user sits on seat cushion 3, their legs and buttocks come into contact with multiple massage bumps 38, which in turn press down vertically on first mounting plate 7 via wear-resistant layer 37, bamboo charcoal fiber antiseptic layer 5, and memory foam layer 6. This first mounting plate 7, cushioned by elasticity via telescopic rod 9 and spring 10, simultaneously presses down on second mounting plate 8. At this point, air in seat cushion 3 is squeezed out through air outlet foam layer 4 and second air outlet 39.

[0030] When a user needs to cool down after sitting on seat cushion 3 for an extended period, they activate silent fan 16 and air pump 24. The silent fan 16 draws air from beneath seat plate 1 through second inlet duct 32 and first inlet duct 18 into first outlet duct 17. The air then enters mounting slot 13 and enters seat cushion 3 through air inlet 12 on positioning plate 11. The air within seat cushion 3 then flows upward through the mesh-structured first and second mounting plates 7 and 8, ultimately escaping through second outlet ducts 39 on memory foam layer 6, bamboo charcoal fiber sterilization layer 5, and wear-resistant layer 37, cooling the user's legs and buttocks while seated on seat cushion 3.

[0031] During this process, the second air outlet pipe 27 draws the air in the first air outlet pipe 17 into the third air outlet pipe 25, and then sends air to the air outlet cavity 21 through the first air outlet hole 28 on the third air outlet pipe 25, and then sends air to the outside of the back panel 20 through the mesh cloth 30, thereby cooling the user's back.

[0032] When the dust filter 19 needs to be replaced, the user unscrews the second bolt 34 and separates it from the first positioning ring 31 and the second positioning ring 33 respectively, then fits the new dust filter 19 to the bottom surface of the first positioning ring 31, and then fits the top surface of the second positioning ring 33 to the bottom surface of the new dust filter 19. At this time, the user screws in the second bolt 34 and threads it through the second positioning ring 33, and the dust filter 19 is threadedly connected to the first positioning ring 31.

[0033] When the bamboo charcoal fiber sterilization layer 5 needs to be cleaned and replaced, the user tears open the Velcro fleece surface 40 to separate it from the Velcro sticky surface 41 , thereby separating the wear-resistant layer 37 from the seat cushion 3 , and then takes the bamboo charcoal fiber sterilization layer 5 out of the leather case.

[0034] When the placement groove 23 needs to be cleaned, the user removes the dust block 35 and separates it from the seat plate 1. After cleaning, the dust block 35 is re-engaged in the opening of the placement groove 23. At this time, the sound insulation cotton 36 is arranged in the placement groove 23.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
