The main body includes a seat and a backrest fixedly connected to the seat. The massage mechanism is detachably mounted on the lower front end of the backrest and includes a fixing plate detachably mounted on the backrest, several sets of airbag components detachably mounted on the fixing plate, and an inflation / deflation device for inflating and deflation the airbag components. The fixing plate is detachably secured to the backrest via several sets of rivets. This rivet-fixed massage mechanism is very inconvenient to disassemble and assemble. Summary of the Invention

[0003] The utility model aims to solve the problems existing in the prior art and proposes a sofa with a back massage function, so as to overcome the defect that the massage mechanism of the prior sofa is inconvenient to assemble and disassemble.

[0004] The utility model is achieved in this way:

[0005] A sofa with a back massage function comprises a backrest, the backrest comprising a frame and a main cushion arranged at the front end of the frame, a massage cover is provided on the front end surface of the main cushion, a massage piece is installed in the massage cover, and an openable and closable opening is provided on the massage cover so that the massage piece can enter and exit the massage cover through the opening.

[0006] The massage element is mounted on the massage cover, preventing it from being exposed and protecting it. The massage element is secured to the main back cushion by the massage cover and can be removed through the opening of the massage cover, making it easy to install and remove. The massage cover is placed on the front surface of the main back cushion. After the massage element is installed, it ensures that the massage element can fully contact the body. Even when the massage element is removed, the main back cushion can still support the body and provide normal sofa functions.

[0007] Preferably, the opening is a single-sided opening located at the lower end of the massage cover. This single-sided opening ensures smooth entry and exit of the massage element while avoiding structural instability and aesthetic issues caused by an overly large opening. Users can easily insert and remove the massage element from the lower end of the massage cover by simply unzipping it, eliminating the need for complex disassembly and assembly. This design not only simplifies the installation and maintenance of the massage element but also significantly enhances the user experience.

[0008] Alternatively, the opening is a three-edge opening located at the lower end and both sides of the massage cover; compared with a single-edge opening, the three-edge opening design further widens the installation and maintenance space of the massage member. The three-edge opening is located at the lower end and both sides of the massage cover, forming a more spacious and flexible entrance.

[0009] The opening is provided with a zipper. Whether it is a single-edge opening or a three-edge opening, the introduction of the zipper not only ensures the firm closure of the opening, preventing the massage member from accidentally falling off during the massage process; but also makes the opening extremely simple and fast to open and close, further improving the user's experience.

[0010] Preferably, the massage cover is sewn and fixed on the main back cushion. Sewing and fixing the massage cover on the main back cushion ensures close connection and cooperation between the two. This fixing method effectively prevents the massage cover from shifting or falling off during use, thereby ensuring the continuous and stable realization of the massage function.

[0011] Preferably, the backrest comprises an outer wrap, the outer wrap comprising a rear outer cover sleeved on the backrest, an upper outer cover fixed on the upper part of the front end of the rear outer cover, and a lower outer cover fixed on the front end of the rear outer cover and located below the upper outer cover, the main back cushion and the massage cover being arranged in the lower outer cover. This can improve the overall aesthetics of the sofa backrest.

[0012] Preferably, the massage cover is provided with a filling layer having a clearance slot, and the massage member is embedded in the clearance slot. The ingenious combination of the filling layer and the clearance slot not only ensures the stable installation of the massage member in the massage cover, but also prevents the massage member from shifting or falling off during use, thereby ensuring the continuous stability and reliability of the massage function.

[0013] Preferably, the front end of the clearance slot is closed, which not only enhances the softness and comfort of the massage cover, but also effectively reduces the direct impact force on the user's back during the massage process through its buffering effect, thereby improving the comfort and safety of the massage. Alternatively, the clearance slot penetrates the filling layer.

[0014] Preferably, the main back cushion is provided with a filler, and the width of the massage cover is less than that of the main back cushion and located in the middle part of the main back cushion. The main back cushion, as the main component of the sofa backrest, is internally filled with an appropriate amount of filler to provide necessary support and comfort. The massage cover, as a functional extension of the main back cushion, has a width designed to be less than that of the main back cushion and located in the middle area of the main back cushion. This design not only ensures that the massage cover can accurately cover the key massage area of the user's back, but also avoids the dispersion or discomfort of the massage effect caused by the excessive width of the massage cover.

[0015] Preferably, the sofa is equipped with a massage control box and an air pump. The massage control box is connected to the air pump, which in turn is connected to the massage elements to inflate them. The massage control box serves as the control center for the entire massage system, receiving user commands and controlling the operating state of the air pump. When the user selects a specific massage mode or intensity, the massage control box sends a corresponding signal to the air pump to adjust its output pressure and flow rate. Based on the received signal, the air pump fills the massage elements with an appropriate amount of air, thereby changing their shape and hardness, achieving a massage effect on the user's back.

[0016] Preferably, the sofa includes a seat frame, a heating plate mounted on the seat frame, and a heating control box installed within the sofa, with the heating plate connected to the heating control box. The heating control box, as the core of the entire heating system, is responsible for receiving user commands and controlling the heating power and temperature of the heating plate. When the user turns on the heating function, the heating control box sends an electrical signal to the heating plate, causing it to generate heat, providing a warm and comfortable sitting experience.

[0017] Preferably, the seat frame includes glue-free cotton, which is wrapped with a fabric layer on the outside. The glue-free cotton has excellent elasticity and resilience, and can fit well into the shape of the seat frame, i.e., the heating plate, providing a comfortable sitting experience. At the same time, the glue-free cotton also has good air permeability and moisture absorption, which can effectively prevent moisture and bacterial growth inside the sofa. The fabric layer serves as the outer layer protection of the glue-free cotton, which not only enhances the aesthetics of the sofa, but also improves its wear resistance and durability. The fabric layer is usually made of high-quality fabric materials, such as cotton, linen, leather, etc., and has the characteristics of softness, comfort, and easy cleaning.

[0018] The utility model provides a sofa with a back massage function, in which massage parts are arranged on a massage cover, thereby avoiding exposure of the massage parts and facilitating protection of the massage parts. The massage parts are fixed by the massage cover fixed on the main back cushion and can be disassembled and assembled through the opening of the massage cover, which is convenient for disassembly and assembly.

[0029] This embodiment provides a sofa with back massage function, such as Figure 1-7 As shown, the backrest 100 includes a frame 120 and a main cushion 130 arranged at the front end of the frame 120, and a massage cover 110 is provided on the front end surface of the main cushion 130. The massage cover 110 contains a massage piece 111, and the massage cover 110 is provided with an openable and closable opening so that the massage piece 111 can enter and exit the massage cover 110 from the opening.

[0030] The massage element 111 is mounted on the massage cover 110, preventing it from being exposed and protecting it. The massage cover 110, which is fixed to the main back cushion 130, secures the massage element 111 and allows for easy assembly and disassembly through the opening of the massage cover 110. The massage cover 110 is mounted on the front surface of the main back cushion 130. Once the massage element 111 is installed, it ensures that it can fully contact the user. Even after the massage element 111 is removed, the main back cushion 130 can still provide support for the user, providing the functionality of a standard sofa.

[0031] like Figure 3As shown, the opening is a single-edge opening located at the lower end of the massage cover 110; the single-edge opening is located at the lower end of the massage cover 110, which design not only ensures that the massage member 111 can smoothly enter and exit the massage cover 110, but also avoids the problem of structural instability and aesthetic appearance caused by an excessively large opening. Users can easily put or take out the massage member 111 from the lower end of the massage cover 110 by simply pulling open the zipper 112, without the need for a complex disassembly and assembly process. This design not only simplifies the installation and maintenance process of the massage member 111, but also greatly improves the convenience of user experience.

[0032] In other optional embodiments, the opening is a three-edge opening located at the lower end and both sides of the massage cover 110; compared with the single-edge opening, the three-edge opening design further widens the installation and maintenance space of the massage member 111. The three-edge opening is located at the lower end and both sides of the massage cover 110, forming a more spacious and flexible entrance.

[0033] Further, the opening is provided with a zipper 112. Whether it is a single-edge opening or a three-edge opening, the introduction of the zipper 112 not only ensures the firm closure of the opening, preventing the massage member 111 from accidentally falling off during the massage process; but also makes the opening extremely simple and fast to open and close, further improving the user's experience. In other optional embodiments, a button can be provided at the opening.

[0034] Further, the massage cover 110 is sewn and fixed on the main back cushion 130. Sewing and fixing the massage cover 110 on the main back cushion 130 ensures the close connection and cooperation between the two. This fixing method effectively prevents the massage cover 110 from shifting or falling off during use, thereby ensuring the continuous and stable realization of the massage function.

[0035] As shown in FIGS. Figure 1 , 2 , 6, the backrest 100 includes an outer wrap 140, which includes a rear outer cover 141 sleeved on the back frame 120, an upper outer cover 142 fixed on the upper part of the front end of the rear outer cover 141, and a lower outer cover 143 fixed on the front end of the rear outer cover 141 and located below the upper outer cover 142. The main back cushion 130 and the massage cover 110 are both arranged in the lower outer cover 143. This can improve the overall aesthetics of the sofa backrest 100. In this embodiment, the upper outer cover 142 and the lower outer cover 143 are integrated, and the middle part is concave inward by sewing, simultaneously forming a separation of the upper space and the lower space. The upper outer cover 142 is normally filled with material to provide support function. In other optional embodiments, the upper outer cover and the lower outer cover can be independent of each other and fixed on the rear outer cover.

[0036] As shown in FIGS. Figure 3-5As shown, the massage cover 110 is provided with a filling layer 113, and the filling layer 113 has a clearance groove 114, and the massage element 111 is embedded in the clearance groove 114. The ingenious combination of the filling layer 113 and the clearance groove 114 not only ensures that the massage element 111 is firmly installed in the massage cover 110, but also prevents the massage element 111 from shifting or falling off during use, thereby ensuring the continuous stability and reliability of the massage function.

[0037] The recess 114 of this embodiment passes through the filling layer 113. In other optional embodiments, Figure 8 As shown, the front end of the recess 114 is closed, which not only enhances the softness and comfort of the massage sleeve 110, but also effectively reduces the direct impact force of the massage element 111 on the user's back during the massage process through its buffering effect, thereby improving the comfort and safety of the massage.

[0038] like Figure 4 As shown, the main cushion 130 is filled with filler, and the massage cover 110 is smaller in width than the main cushion 130 and is located in the middle of the main cushion 130. As the main component of the sofa backrest 100, the main cushion 130 is filled with an appropriate amount of filler to provide the necessary support and comfort. The massage cover 110, as a functional extension of the main cushion 130, is designed to be smaller in width than the main cushion 130 and is located in the middle area of ​​the main cushion 130. This design not only ensures that the massage cover 110 can accurately cover the key massage areas of the user's back, but also avoids the scattered massage effect or discomfort caused by the massage cover 110 being too wide.

[0039] like Figure 3 As shown, the sofa is equipped with a massage control box 200 and an air pump. The massage control box 200 is connected to the air pump, which is then connected to the massage elements 111 to inflate the elements 111.
