The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0032] Example 1

[0033] Please see Figures 1-7As shown, this utility model discloses a massage chair, including a backrest 1, a seat 2, and a massage mechanism 3. The backrest 1 has a vertically extending hollow section 4, the lower end of which extends through the seat 2. A travel guide rail 5 is provided within the hollow section 4, and the massage mechanism 3 is movably mounted on the travel guide rail 5, allowing it to move vertically between the backrest 1 and the seat 2 along the travel guide rail 5. Specifically, travel guide rails 5 are provided on the left and right sides of the hollow section 4, and the left and right ends of the massage mechanism 3 are slidably mounted on the travel guide rails. This invention also includes at least one inflatable airbag connected to an inflation / deflation control module (not shown in the figure). The airbag is positioned outside the perforated portion 4 and at least covers a portion of the perforated area of ​​the perforated portion 4 to provide support for the corresponding part of the human body when inflated. Furthermore, the airbag can provide clearance for the massage mechanism 3 by deflating or partially deflating, preventing the massage mechanism 3 from being too far from the corresponding part of the human body due to inflation, thus ensuring the massage mechanism 3 can effectively massage the body. Deflating or partially deflating the airbag allows the massage mechanism 3 to be closer to the body, thereby improving the massage effect. Specifically, this invention allows the inflation / deflation control module to control the airbag to deflate or partially deflate when the massage mechanism 3 is in operation or when it moves to a position corresponding to the airbag. This invention can also control the periodic inflation / deflation of the airbag through the inflation / deflation control module, allowing the airbag to continue massaging the corresponding part of the human body. Periodic inflation and deflation refers to the alternating inflation and deflation of the air bag at set time intervals. This process is cyclical and forms a periodic action. The inflation and deflation control module includes an air pump and a main control board. The main control board is connected to the air pump to control the air pump to inflate or deflate the air bag.

[0034] Therefore, when the massage mechanism is not in operation, this invention can support the corresponding parts of the human body through the inflated air bag, thereby significantly alleviating the feeling of collapse caused by the hollow design and improving user comfort. When the massage mechanism 3 is in operation, the air bag is deflated or partially deflated to avoid spatial interference with the massage mechanism 3 and thus affecting the massage effect on the corresponding parts of the human body.

[0035] In a preferred embodiment, multiple airbags are provided, including a first airbag 6 located on the backrest 1, which at least covers the hollowed-out area of ​​the perforated portion 4 corresponding to the waist of the user. Furthermore, the multiple airbags also include a second airbag 7 located on the seat 2, which covers the hollowed-out area of ​​the perforated portion 4 on the seat 2. The first airbag 6 and the second airbag 7 are separately provided, but this is not a limitation. In other embodiments, the first airbag 6 and the second airbag 7 are integrally formed, or connected together. In other embodiments, the first airbag 6 and the second airbag 7 are not included simultaneously; instead, only the first airbag 6 or the second airbag 7 is provided according to the user's actual needs. For example, the user can choose to provide either the first airbag 6 or the second airbag 7 according to the support requirements of different body parts to obtain the best user experience.

[0036] In this embodiment, the air bag includes a central air chamber, a left air chamber, and a right air chamber. The central air chamber is positioned corresponding to the perforated portion 4. The left and right air chambers are located on the left and right sides of the central air chamber, respectively. The central air chamber is designed to be independently controlled for inflation and deflation, and it provides clearance for the massage mechanism 3 during massage by deflating. Therefore, the central air chamber is independent of the left and right air chambers, and their inflation and deflation states do not affect each other. Furthermore, each of the central, left, and right air chambers includes multiple air chambers arranged in multiple rows and / or columns. The direction of the columns is consistent with the extension direction of the perforated portion 4, and the direction of the rows is perpendicular to the extension direction of the perforated portion 4.

[0037] Specifically, such as Figure 3 As shown, the middle air chamber A of the first air bag 6 includes three air chambers A1, A2, and A3 arranged in a row; its right air chamber B includes three air chambers B1, B2, and B3 arranged in a row; and its left air chamber C includes a row of air chambers composed of multiple first air chambers. Figure 4 As shown, the middle air chamber D of the second air bag 7 includes two rows of air chambers. The row of air chambers closest to the first air bag 6 includes multiple rows of air chambers D1, D2, and D3, while the other row includes only a single air chamber D4. Air chamber D4 is elongated and extends along the left and right directions of the base 3. The right air chamber E of the second air bag 7 includes two air chambers E1 and E2 arranged in a row, and the left air chamber F of the second air bag 7 includes two air chambers F1 and F2 arranged in a row. The number of air chambers contained in the middle, left, and right air chambers of each air bag, as well as the arrangement of the air chambers, are not limited to this.

[0038] This utility model also includes an outer cover (not shown in the figure, but can also be called an outer cover) that covers the backrest 1, the seat 2, and each air bag. Therefore, each air bag (i.e., the first air bag 6 and the second air bag 7) can be pre-sewn onto the outer cover and then assembled with the outer cover to fit onto the backrest 1 or the seat 2. Alternatively, each air bag can be directly connected to the backrest 1 or the seat 2, specifically by using screws or other fixing methods to connect the air bags to the backrest 1 or the seat 2.

[0039] In this embodiment, the backrest 1 and the seat 2 are fixed together to form the main body of the chair frame. This invention also includes a base frame 8 and a backrest push rod 9. The main body of the chair frame is angle-adjustable on the base frame 8. The backrest push rod is hinged to the front end of the base frame 8, and the backrest push rod 9 has a slider 91 that can reciprocate along the front-back direction of the base frame 8. This slider 91 is hinged to the main body of the chair frame. Thus, the angle can be adjusted by sliding the slider 91 back and forth, causing the main body of the chair frame to flip back and forth, especially achieving a zero-gravity state.

[0040] This utility model also includes a lower leg support (not shown in the figure) and a lower leg push rod 10. The lower leg support is hinged to the front end of the seat 2, one end of the lower leg push rod 10 is hinged to the seat 2, and the other end of the lower leg push rod 10 is movably engaged with the lower leg support.

[0041] The working principle of this massage chair is as follows:

[0042] After powering on, the first air bag 6 on the backrest 1 and the second air bag 7 on the seat 2 both begin to inflate and maintain pressure, such as Figure 5 As shown, users will not sink when sitting on it, improving the seating comfort.

[0043] After the massage program is started, the massage mechanism 3 moves up and down along the guide rail 5 in the hollowed-out part 4, massaging the user's buttocks and waist. Simultaneously, the inflation / deflation control module controls the deflation of the intermediate air chamber A of the first air bag 6 and the intermediate air chamber D of the second air bag 7. Figure 6 As shown, this provides clearance for the massage mechanism 3. During this process, the left air chamber C and right air chamber B of the first air bag 6, and the left air chamber F and right air chamber E of the second air bag 7, can massage the sides of the buttocks and the sides of the waist by periodically inflating and deflating the air.

[0044] After the massage mechanism 3 stops massaging, the middle air chamber A of the first air bag 6 and the middle air chamber D of the second air bag 7 are re-inflated and pressurized, so that the first air bag 6 and the second air bag 7 provide complete support for the user's waist and hips, making it convenient for the user to sit on the massage chair to rest or sleep. Before and after the massage mechanism 3 massages, the air chambers of the first air bag 6 and the second air bag 7 can also be periodically inflated and deflated synchronously to achieve kneading massage of the user's waist and hips.

[0045] After the massage ends and the user stands up, the first air bag 6 and the second air bag 7 automatically deflate, as... Figure 7 As shown, the system enters standby mode, waiting for the next massage to begin.

[0046] Example 2

[0047] Please see Figure 8 , Figure 9 As shown, the massage chair of this utility model differs from the first embodiment mentioned above in that: the air bag includes multiple air chambers arranged along the extension direction of the hollow part 4, each air chamber is elongated and spans the hollow part 4, that is, each air chamber extends along the left and right directions of the massage chair.

[0048] In this embodiment, the air bag of the present invention also includes a first air bag 6 located on the backrest 1 and a second air bag 7 located on the seat 2. The first air bag 6 includes a plurality of air chambers G arranged along the extension direction of the hollow portion 4, and the second air bag 7 includes a plurality of air chambers H arranged along the extension direction of the hollow portion 4.

[0049] The working principle of this massage chair is as follows:

[0050] After powering on, the first air bag 6 on the backrest 1 and the second air bag 7 on the seat 2 both begin to inflate and maintain pressure, such as Figure 8 As shown, users will not sink when sitting on it, improving the seating comfort.

[0051] After the massage program is started, the massage mechanism 3 moves up and down along the guide rail 5 in the hollowed-out section 4, massaging the user's buttocks and waist. Simultaneously, the inflation / deflation control module controls the deflation of the first air bag 6 and the second air bag 7. Figure 8 As shown, this provides clearance for the massage mechanism 3.

[0052] After the massage mechanism 3 stops massaging, the first air bag 6 and the second air bag 7 are re-inflated and pressurized, providing support for the user's waist and hips, making it convenient for the user to rest or sleep in the massage chair. Before and after the massage mechanism 3 starts massaging, the air chambers of the first air bag 6 and the second air bag 7 can also be periodically inflated and deflated synchronously to achieve a kneading massage of the user's waist and hips.

[0053] After the massage ends and the user stands up, the first air bag 6 and the second air bag 7 automatically deflate, and the system enters standby mode, waiting for the next massage to begin.

[0054] The massage chair of this utility model has parts not covered (such as the structure and working principle of the inflation / deflation control module) that are the same as or can be implemented using existing technology.

[0055] The above embodiments are only used to further illustrate a massage chair of the present invention, but the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the technical solution of the present invention.
