[0024] In traditional ergonomic chairs, the seat cushion will always fit the user, and the comfort of the seat cushion has always been an important criterion for users to purchase; seat cushions can be roughly divided into two categories. One is a seat cushion with a cotton interlayer. The cotton interlayer can provide a better covering and fitting effect, and as the use time goes on, it fits the user's body characteristics better and is more comfortable, but the air permeability is poor. In the market, the cotton interlayer of this type of seat cushion cannot be disassembled by users after sale. Therefore, it is difficult for users to clearly judge the material of the cotton interlayer. If "black heart cotton" is used as the interlayer material, it will seriously affect the user's health in long-term use. Health; one is the elastic mesh seat cushion. The biggest advantage of this seat cushion is that it looks good and has strong breathability, but the production cost is high, and the life of the mesh material is relatively poor, and there is no need to worry about the "black heart cotton" problem, and because the mesh material is installed according to the tension principle, the fit between the user and the elastic mesh seat cushion is not high, and the sitting feel is poor; the above two seat cushions have their own advantages and disadvantages, but there is no way to adjust the softness and hardness by themselves, and users cannot adjust the chair to the sitting feel that suits their preference to improve the comfort of long-term sitting. Therefore, there is an urgent need for a chair seat structure with a more reasonable structure to solve the above-mentioned disadvantages.

[0025] In order to solve the above-mentioned technical problems, the present application provides a chair seat structure with adjustable sitting feel. Please refer to Figures 1 to 6. The chair seat structure includes a cover bag 1 and a base plate 2. The outer edge of the base plate 2 is fixedly connected to the bag opening of the cover bag 1 to form an adjustment cavity. The adjustment cavity is also filled with at least two soft core layers 3 with different soft and hard parameters and breathability parameters; wherein, the bag body of the cover bag 1 is also provided with a zipper structure 13, and the zipper structure 13 slides open to form an opening for adjusting the soft core layer 3; during the use of the present application, the soft layer core is taken out through the opening, and multiple soft core layers 3 are arranged according to different needs of the user. The order of filling the soft core layers of different materials in the adjustment cavity can realize the adjustment of the softness, hardness and breathability of the seat structure. The user can better adjust it according to his own needs, seek the softness, hardness and breathability parameters that suit him, and can also maintain the degree of fit with the user's body, that is, the user can adjust the filling order of the soft core layers of different materials to customize the heat dissipation performance and softness of the seat structure, thereby optimizing the sitting comfort; and the overall structure processing technology is simple and the production cost is low; further, the user can also check the material of the soft core layer 3 through the zipper structure 13, without worrying about buying "black core cotton". Modes for Carrying Out the Invention

[0026] In this embodiment, a side of the bottom plate 2 away from the bag 1 is further provided with a plurality of heat dissipation holes 21, and the plurality of heat dissipation holes 21 are connected to the adjustment cavity; it is not difficult to understand that the plurality of heat dissipation holes 21 are used to further increase the overall heat dissipation of the chair seat structure; specifically, since the user sits on the chair seat structure for a long time and accumulates a certain amount of heat, the heat dissipation holes 21 can achieve ventilation and heat dissipation effects, thereby improving the comfort of sitting for a long time and avoiding the phenomenon of stuffiness and sweating.

[0027] In this embodiment, a receiving groove for receiving legs is further provided on one side of the bottom plate 2 close to the bag 1 ; it is easy to understand that the receiving groove can form a good receiving area 23 for the user's legs, further improving comfort.

[0028] As for the installation of the base plate 2 and the cover bag 1, a mounting groove 22 is further provided on the side of the base plate 2 away from the cover bag 1, and the side material of the cover bag 1 forming the bag opening is fixed in the mounting groove 22 to form an adjustment cavity; it is not difficult to understand that by fixing the bag opening side material of the cover bag 1 with the mounting groove 22 through adhesive, needle and thread sewing or thread pressing, the adjustment cavity structure of the present application can be obtained so that the soft core layer 3 can be placed as a filling material.

[0029] As for the selection of the soft layer, in this embodiment, the soft core layer 3 is at least two of a sponge pad, a 3D mesh pad or an air fiber pad; it is not difficult to understand that sponge pads, 3D mesh pads and air fiber pads are all selected styles as the inner core of the seat cushion in this field. For example, the soft core layer 3 is a combination of a sponge pad and an air fiber pad. When the customer needs to use it in summer or when the weather is hot, the air fiber pad is placed on the upper part of the sponge pad, and the air fiber pad is in contact with the user as a permeable bag 1. The air fiber pad can ensure the required air permeability and prevent stuffiness, and the softness and hardness of the composite of the sponge pad and the air fiber pad can also be guaranteed. If the hardness needs to be further increased, a 3D mesh pad can be added to increase the hardness. Increase the overall hardness; for example, when the customer needs to use it in winter or relatively cold conditions, the sponge pad needs to be placed on the air fiber and 3D mesh pad to ensure the soft wrapping of the user when sitting down, and the sponge material has poor air permeability but brings improved warmth retention, which is more suitable for application scenarios such as winter. If the hardness needs to be further reduced, the air fiber pad can be pulled out; better, when the soft core layer 3 is a sponge pad, the surface of the sponge pad is provided with multiple groups of heat dissipation holes; in another preferred embodiment, the material of the bag is 3D breathable mesh, which further increases the overall heat dissipation performance of the chair seat structure; and the soft core layer can also be an elastic soft pad with a spring inside to further expand the breathability parameters and soft and hard parameters.

[0030] In this embodiment, the bag 1 is further provided with an elastic portion 12, which is arranged around the bag body of the bag 1; it is not difficult to understand that the elastic portion 12 can make the accommodating space of the adjustment cavity change with the number of soft core layers 3, so as to better fix the soft core layer 3; in actual operation, the elastic portion 12 can be made of a fabric with good elasticity, such as elastic nylon or elastic fiber, and is arranged on the bag body by splicing and sewing;

[0031] As for the assembly details of the zipper structure 13, it can be understood that the bottom of the bag 1 covers the soft core layer 3 at the end to form the seating area 11; the zipper structure 13 is located on the side of the elastic part 12 away from the seating area 11, and the user can more conveniently open the seating area 11 to expose the adjustment cavity and thus control the matching order between the soft core layers 3.

[0032] In this embodiment, a fan assembly 32 is also included. The edges of multiple soft core layers 3 together form a ventilation cavity 33, and the fan assembly 32 is accommodated in the ventilation cavity 33. This implementation scheme can be clearly recorded in the patent publication number CN212972463U, so it will not be repeated. Industrial Applicability

[0033] 1) The soft core layer is removed through the opening, and multiple soft core layers are filled into the adjustment cavity in different orders according to the user's needs, thereby adjusting the softness, hardness, and breathability of the seat structure. The user can better adjust the seat structure according to their own needs, find the softness, hardness, and breathability parameters that suit them, and maintain a close fit with the user's body. The overall structure is simple to process and has low production costs.

[0034] 2) Furthermore, users can also check the material of the soft core layer through the zipper structure, without having to worry about buying "black core cotton".

[0035] The above disclosures are only a few specific embodiments of the present invention, but the present invention is not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
