In severe cases, this can even lead to illness, thus affecting their normal life. To alleviate muscle or skeletal discomfort, various types of massage devices have been proposed in the related art, such as negative pressure belts, which utilize negative pressure to absorb the user's massaged area. However, the negative pressure absorption effect of the negative pressure belts provided in the related art is easily lost. Utility Model Content

[0009] The negative pressure belt comprises:

[0010] The belt body includes a middle belt body and two connecting belts, the two connecting belts are respectively connected to opposite ends of the middle belt body, and a connection is formed between the connecting belts and the middle belt body.

[0013] The waist belt body has a width direction, the intermediate belt body has a first edge and a second edge that are separated from each other in the width direction, and the air receiving component has a first boundary adjacent to the first edge and a second boundary adjacent to the second edge;

[0014] In which, the first edge is spaced apart from the first boundary so that the portion of the intermediate belt body located between the first edge and the first boundary constitutes a first flexible portion; the second edge is spaced apart from the second boundary so that the portion of the intermediate belt body located between the second edge and the second boundary constitutes a second flexible portion, and the air receiving portion of the negative pressure massage head is arranged toward the air receiving assembly so that the air receiving portion avoids the first flexible portion or the second flexible portion.

[0015] In which, the air receiving component has a connecting part, which faces the negative pressure massage head. At least one of the connecting part and the air receiving part is a hard tube.

[0023] In the negative pressure belt provided in this embodiment, by arranging the air receiving part on the side of the negative pressure tank away from the connecting belt, it is possible to avoid the connection where the degree of bending may be large, and to avoid squeezing the air receiving part when the connection is greatly bent, which may cause the connection between the negative pressure tank and the air receiving component to be disconnected, so that the air receiving component and the negative pressure tank are always connected. In this way, it can be ensured that the negative pressure massage head maintains a better negative pressure state and will not fail.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] References herein to "embodiments" or "implementations" mean that a particular feature, structure, or characteristic described in connection with the embodiments or implementations may be included in at least one embodiment of the present application. The appearance of such phrases in various places in the specification does not necessarily refer to the same embodiment, nor do they constitute independent or alternative embodiments that are mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0037] Please refer to Figure 1 and Figure 2 The present application provides a negative pressure belt 100 , which includes: a belt body 10 , an air receiving component 30 , and at least two negative pressure massage heads 20 .

[0038] The belt body 10 includes a middle belt body 11 and two connecting belts 12. The two connecting belts 12 are respectively connected to opposite ends of the middle belt body 11. A connection 13 is formed between the connecting belts 12 and the middle belt body 11. The negative pressure belt 100 can be worn on the part to be massaged. When the negative pressure belt 100 is in the use state, the connection 13 is bent.

[0039] The air receiving assembly 30 is disposed on the middle belt body 11 .

[0040] In which, the at least two negative pressure massage heads 20 are respectively arranged on opposite sides of the air receiving component 30, and the negative pressure tank 210 has an air receiving portion 213, and the air receiving portion 213 is connected to the air receiving component 30 through a connecting pipe 40, wherein the air receiving portion 213 is arranged on the side of the negative pressure tank 210 away from the connecting belt 12, so as to be away from the connection 13 between the connecting belt 12 and the intermediate belt body 11, thereby avoiding compressing the connection 13 between the connecting pipe 40 and the air receiving portion 213 when the connection 13 is bent.

[0041] In the negative pressure belt 100 provided in this embodiment, by arranging the air receiving portion 213 on the side of the negative pressure tank 210 away from the connecting belt 12, the connection 13 that may have a large degree of bending can be avoided, so as to avoid squeezing the air receiving portion 213 when the connection 13 has a large bending, thereby preventing the connection between the negative pressure tank 210 and the air receiving component 30 from being disconnected, so that the air receiving component 30 and the negative pressure tank 210 are always connected. In this way, it can be ensured that the negative pressure massage head 20 maintains a better negative pressure state and will not fail. Therefore, the negative pressure belt 100 provided in this application can be stably adsorbed on the part to be massaged.

[0042] The negative pressure belt 100 is further described below.

[0043] The negative pressure belt 100 is used to massage a desired area. The desired area is a human body, and may include, but is not limited to, the neck, arms, legs, waist, back, and the like. The following description of this application uses the waist as an example. It is understood that these examples should not be construed as limiting the embodiments of this application.

[0044] The negative pressure belt 100 comprises: a belt body 10, an air receiving assembly 30, and at least two negative pressure massage heads 20. The belt body 10, the air receiving assembly 30, and the negative pressure massage heads 20 are described in detail below with reference to the accompanying drawings.

[0045] The belt body 10 is the part that the user wears on the part to be massaged when using the negative pressure belt 100. The belt body 10 is made of a flexible material so that it can be deformed to adapt to the user's body curve. The flexible material of the belt body 10 can be understood as a material that can be bent or curved. For example, the material of the belt body 10 can include at least one of cloth and soft rubber material. The negative pressure belt 100 has a non-use state (such as Figure 1 As shown in FIG), in this state, the belt body 10 can be flattened and formed into a long strip, so the belt body 10 has an extension direction F1, which is the length direction of the belt body 10 when it is flattened. The negative pressure belt 100 also has a use state that can be worn on the part to be massaged (as shown in FIG). Figure 2As shown), in this state, the belt body 10 is wrapped into a roughly closed-loop annular structure, which defines a wearing space K9. The wearing space K9 is used to accommodate the area to be massaged, that is, the user can wear the belt body 10 around his or her waist.

[0046] Please refer to Figure 1 The waist belt body 10 includes a middle belt body 11 and two connecting belts 12. The two connecting belts 12 are respectively connected to the opposite ends of the middle belt body 11.

[0047] A connection 13 is formed between the connecting belt 12 and the intermediate belt body 11. When the negative pressure waist belt 100 is in use, the connection 13 is curved. The intermediate belt body 11 has two mounting areas A1 and a middle area A2 located between the two mounting areas A1. The mounting area A1 is closer to the connection 13 between the connecting belt 12 and the intermediate belt body 11 than the middle area A2. In other words, the two mounting areas A1 are located along the length of the belt body 10, on opposite sides of the middle area A2.

[0048] It should be noted that the two installation areas A1 are located on either side of the middle area A2. The two installation areas A1 and the middle area A2 are divided along the length of the waistband body 10. The dividing line between the two installation areas A1 and the middle area A2 can be real, that is, the dividing line can be observed on the actual product. Of course, the dividing line between the two installation areas A1 and the middle area A2 can also be non-real, that is, the dividing line is artificially defined and does not exist on the actual product. The dividing line can extend along the width of the waistband body 10. The dividing line can be a straight line or a curve.

[0049] The air receiving assembly 30 is disposed in the middle area A2 and is used to discharge the air in the negative pressure massage head 20 so that the air pressure in the negative pressure massage head 20 reaches a preset negative pressure value, thereby stably adsorbing the negative pressure massage head 20 on the area to be massaged.

[0050] Please refer to Figure 3 The negative pressure massage head 20 is a device that can be attached to the massaged area through negative pressure and massage the massaged area. Negative pressure refers to a gas pressure state lower than normal pressure (commonly known as one atmosphere). In other words, the negative pressure massage head 20 can create a negative pressure effect. Under the influence of external atmospheric pressure, the negative pressure massage head 20 will be "pressed" on the massaged area, that is, the negative pressure massage head 20 appears to be "attached" to the massaged area.

[0051] Please refer to further Figure 4Each mounting area A1 is provided with at least one negative pressure massage head 20, thus the negative pressure belt 100 includes at least two negative pressure massage heads 20. The negative pressure massage head 20 includes a negative pressure tank 210, which has an air receiving portion 213 that communicates with the interior of the negative pressure tank 210. The air receiving portion 213 can be an opening on the negative pressure tank 210 or a hollow tube. The subsequent embodiments will illustrate the air receiving portion 213 as a tube. The air receiving portion 213 is connected to the air receiving assembly 30 via a connecting tube 40. The air receiving portion 213 is located on the side of the negative pressure tank 210 facing the middle area A2, away from the connection 13 between the connecting belt 12 and the middle belt body 11. This prevents compression of the connection between the connecting tube 40 and the air receiving portion 213 when the connection 13 is curved. The connecting tube 40 can be a flexible, flexible tube.

[0052] Specifically, when the user wears the negative pressure belt 100 around the waist, the middle belt body 11 faces the user's back, and the two connecting belts 12 wrap around the user's abdomen. The connection 13 between the connecting belts 12 and the middle belt body 11 will bend adaptively. If the connection between the connecting tube 40 and the air receiving portion 213 is too close to the connection 13, the bending of the connection 13 may cause the connection tube 40 to break, resulting in the air receiving assembly 30 being unable to control the negative pressure massage head 20 to maintain the preset negative pressure value, and even causing the negative pressure adsorption effect of the negative pressure massage head 20 to fail. In the present application, since the air receiving portion 213 is arranged on the side of the negative pressure tank 210 facing the middle area A2, or in other words, the extension direction of the central axis of the air receiving portion 213 passes through the air receiving assembly 30, it can avoid the connection 13 with a larger degree of bending, and avoid squeezing the air receiving portion 213 when the connection 13 has a large bending, which causes the connection between the negative pressure tank 210 and the air receiving assembly 30 to be disconnected, so that the air receiving assembly 30 and the negative pressure tank 210 are always connected, thereby ensuring that the negative pressure massage head 20 maintains a better negative pressure state and will not fail. In other words, the negative pressure belt 100 provided in the present application can be stably adsorbed on the part to be massaged.

[0053] Please refer to further Figure 5 The waistband body 10 has a width direction F2 that is perpendicular to the extension direction F1. The intermediate belt body 11 has a first edge S3 and a second edge S4 that are spaced apart in the width direction F2. The first edge S3 and the second edge S4 are the two contour edges of the intermediate belt body 11 that are spaced apart in the width direction F2. The air receiving assembly 30 has a first boundary S5 adjacent to the first edge S3 and a second boundary S6 adjacent to the second edge S4. The first boundary S5 and the second boundary S6 are the two contour edges of the air receiving assembly 30 in the width direction F2.

[0054] The first edge S3 is spaced apart from the first boundary S5, so that the portion of the intermediate strip 11 between the first edge S3 and the first boundary S5 constitutes a first flexible portion 111. The second edge S4 is spaced apart from the second boundary S6, so that the portion of the intermediate strip 11 between the second edge S4 and the second boundary S6 constitutes a second flexible portion 112. Both the first flexible portion 111 and the second flexible portion 112 are bendable or flexible.

[0055] When the user wears the negative pressure belt 100 around the waist, the relative direction of the first flexible portion 111 and the second flexible portion 112 is the user's height. It is understood that during the massage process, the user may make movements such as leaning forward and backward. At this time, the user's body bends in the direction of the body height, and the first flexible portion 111 or the second flexible portion 112 is squeezed by the body and flexibly bends. This prevents the user's body from directly pressing against the air receiving assembly 30 when bending, which would cause the user to feel an excessively hard object supporting the body. In other words, the first flexible portion 111 and the second flexible portion 112 flexibly separate the user's body from the air receiving assembly 30.

[0056] Furthermore, the air receiving portion 213 of the negative pressure massage head 20 is positioned toward the air receiving assembly 30, so that it avoids the first flexible portion 111 or the second flexible portion 112. This shortens the air receiving line between the negative pressure massage head 20 and the air receiving assembly 30. Specifically, if the air receiving portion 213 is positioned toward the first edge S3 and the second edge S4, the significant force generated by a person squeezing the first and second flexible portions 111 and 112 when leaning forward or backward will be transmitted to the air receiving portion 213, potentially damaging the air receiving portion 213 and failing to maintain negative pressure, which could in turn render the negative pressure absorption effect of the negative pressure massage head 20 ineffective. In this embodiment, the air receiving portion 213 is positioned toward the air receiving assembly 30, away from the first and second edges S3 and S4. When a person leans forward or backward and squeezes the first and second flexible portions 111 and 112, no significant force is transmitted to the air receiving portion 213, thereby ensuring that the negative pressure absorption effect of the negative pressure massage head 20 is maintained.

[0057] Please refer to Figure 4The air receiving assembly 30 has a connecting portion 330, and the connecting portion 330 faces the negative pressure massage head 20, that is, the connecting portion 330 faces the installation area A1. At least one of the connecting portion 330 and the air receiving portion 213 is a hard tube. In one embodiment, the connecting portion 330 is a hard tube, and the air receiving portion 213 is a soft tube. In another embodiment, the connecting portion 330 is a hard tube, and the air receiving portion 213 is a soft tube. In yet another embodiment, both the connecting portion 330 and the air receiving portion 213 are hard tubes. Herein, a hard tube refers to a tube body that is relatively hard and not easy to bend, and a soft tube refers to a tube body that is relatively soft and flexible.

[0058] Please refer to further Figure 5 and Figure 6 The connecting portion 330 is connected to the air receiving portion 213 via the connecting tube 40. A space K10 is formed between the connecting portion 330 and the air receiving portion 213. The region of the intermediate belt body 11 corresponding to the space K10 forms a deformable portion 113. The waist belt body 10 has a width F2, and the deformable portion 113 extends along this width F2, allowing the negative pressure electrode massage head to float relative to the air receiving assembly 30 along with the deformable portion 113.

[0059] Specifically, when viewed from the left side to the right side (or vice versa), the back of the human body exhibits an undulating trend. When the negative pressure belt 100 is worn around the waist, in order to ensure good adsorption of the negative pressure massage head 20, the negative pressure belt 100 should also be adapted to the undulating trend of the back.

[0060] In this embodiment, the intermediate strip 11 has a deformable portion 113 extending along the width direction F2. The orthographic projection of the spacing space K10 on the intermediate strip 11 falls within the area of ​​the deformable portion 113. In other words, the spacing space K10 faces the deformable portion 113. In the extension direction F1 of the intermediate strip 11, the dimensions of the spacing space K10 are less than or equal to the dimensions of the deformable portion 113. In the width direction F2 of the intermediate strip 11, the dimensions of the spacing space K10 are less than the dimensions of the deformable portion 113. It will be appreciated that, in this embodiment, since the deformable portion 113 corresponds to the spacing space K10 between the connecting portion 330 and the air receiving portion 213, the deformable portion 113 can bend without significantly affecting the connecting portion 330 or the air receiving portion 213. Through the bending of the deformable portion 113, the installation area A1 can swing slightly in the thickness direction of the waist belt body 10 based on the deformable portion 113 relative to the middle area A2, so that the negative pressure massage head 20 can float slightly in the thickness direction of the waist belt body 10 relative to the air receiving component 30 during the adsorption process. In this way, the negative pressure massage head 20 can adapt to different human backs with undulating movements and realize adaptive negative pressure adsorption massage.

[0061] Please refer to Figure 4 The air receiving assembly 30 includes a negative pressure generator 310 and a control box 320. The negative pressure generator 310 is disposed within the control box 320. The negative pressure generator 310 is connected to the negative pressure tank 210 via the air receiving portion 213 to provide a negative pressure effect to the negative pressure tank 210. The control box 320 is at least partially a rigid structure, which is used to prevent deformation transfer between the intermediate belt body 11 located on both sides of the rigid structure along the length of the waist belt body 10. In other words, the rigid structure is used to prevent deformation transfer between the two mounting areas A1.

[0062] Specifically, the negative pressure generator 310 is connected to the air receiving portion 213 via the connection portion 330, thereby connecting to the negative pressure tank 210. The negative pressure generator 310 is used to provide negative pressure to the negative pressure massage head 20, allowing the negative pressure massage head 20 to be negatively attracted to the massage area. The control box 320 is a box structure that houses and protects the negative pressure generator 310. The control box 320 is at least partially rigid. "Rigid" here means that it is relatively resistant to deformation relative to the waist belt body 10, and the rigid structure refers to the harder portion of the control box 320. Of course, in some embodiments, the entire control box 320 can be rigid. Since the control box 320 is arranged between the two installation areas A1, the deformation caused by each negative pressure massage head 20 in the corresponding installation area A1 during negative pressure adsorption is not easily transmitted to the other installation area A1, that is, the control box 320 will hinder the deformation transmission between the two installation areas A1), thereby avoiding affecting the normal operation of the other negative pressure massage head 20, so that each negative pressure massage head 20 is adsorbed independently without interfering with each other.

[0063] Please refer to Figure 7 The negative pressure tank 210 has a tank opening K1 and a negative pressure chamber K2, wherein the tank opening K1 is connected to the negative pressure chamber K2. The negative pressure chamber K2 is connected to the air receiving assembly 30 via the air receiving portion 213. The air receiving assembly 30 can exhaust at least part of the air in the negative pressure chamber K2 to form a negative pressure. The air receiving portion 213 is disposed between the tank opening K1 and the bottom surface of the negative pressure tank 210 facing away from the tank opening K1, so that the air receiving portion 213 is located between the skin-proximal layer 110 and the skin-distal layer 120 of the intermediate belt body 11.

[0064] With the above arrangement, the negative pressure tank 210 is not easily deformed by external forces, and thus the negative pressure tank 210 is not easily disconnected from the air receiving portion 213 due to deformation. Furthermore, the connection between the air receiving portion 213 and the negative pressure tank 210 is located between the two ends of the negative pressure tank 210, and is therefore not easily affected by external forces. This improves the stability of the connection between the air receiving portion 213 and the negative pressure tank 210, thereby ensuring a stable negative pressure effect.

[0065] Please refer to Figure 7 The negative pressure massage head 20 further includes a flexible edge 220, which is connected to the negative pressure tank 210. The flexible edge 220 has a suction port K3 for sucking the part to be massaged, and the suction port K3 is connected to the negative pressure chamber K2 through the tank port K1.

[0066] The belt body 10 includes a skin-near layer 110 and a skin-distal layer 120 disposed opposite each other. The skin-near layer 110 refers to the material layer located on the side of the belt body 10 facing the wearing space K9. In other words, the skin-near layer 110 is the material layer on the side of the belt body 10 that is closer to the user when the negative pressure belt 100 is worn. The skin-distal layer 120 refers to the material layer on the side of the belt body 10 that is away from the wearing space K9. In other words, the skin-distal layer 120 is the material layer on the side of the belt body 10 that is farther away from the user when the negative pressure belt 100 is worn.

[0067] The end of the negative pressure tank 210 away from the flexible surrounding edge 220 forms a force-bearing end 2111, which is the tail of the negative pressure tank 210. The force-bearing end 2111 is in contact with the skin-distal layer 120. When the belt body 10 is worn on the part to be massaged, the skin-distal layer 120 applies force to the force-bearing end 2111 so that the flexible surrounding edge 220 is tightly attached to the part to be massaged. In other words, the skin-distal layer 120 can support the tail of the negative pressure tank 210, thereby effectively preventing the negative pressure tank 210 from moving backward relative to the belt body 10, and ensuring that the flexible surrounding edge 220 is stably attached to the part to be massaged. This embodiment can also be understood as follows: if the negative pressure belt 100 is to be stably worn on the part to be massaged, the belt body 10 needs to be tightened to be tied tightly to the part to be massaged, otherwise it will become loose and easy to fall off. When the waist belt body 10 is worn on the part to be massaged, the waist belt body 10 forms a wearing space K9, and the waist belt body 10 in a taut state tends to shrink the wearing space K9. Since the force-bearing end 2111 of the negative pressure tank 210 is located on the side of the distal skin layer 120 close to the proximal skin layer 110, the distal skin layer 120 will apply a force toward the proximal skin layer 110 on the force-bearing end 2111, so that the flexible edge 220 can be closely attached to the part to be massaged, ensuring that the negative pressure massage head 20 is stably adsorbed on the part to be massaged.

[0068] Optionally, the skin-distal layer 120 is a non-elastic layer. For example, the skin-distal layer 120 is a non-elastic fabric layer such as a cotton layer, a linen layer, or a wool layer. When the negative pressure belt 100 is worn on the part to be massaged, the skin-distal layer 120 covers the force-bearing end 2111 to apply force to the force-bearing end 2111. Through the above arrangement, when the skin-distal layer 120 applies a resisting force to the force-bearing end 2111, since the skin-distal layer 120 is a non-elastic layer, it is not easily deformed by force, thereby ensuring that the resisting force can be quickly transmitted to the flexible surrounding edge 220. At the same time, the non-elastic skin-distal layer 120 can provide a certain degree of hard support to the force-bearing end 2111, reducing the backward movement of the negative pressure massage head 20, thereby improving the stability of the flexible surrounding edge 220 after contact with the skin, and facilitating the flexible surrounding edge 220 to fully and stably fit the skin.

[0069] Please refer to Figure 7 The negative pressure tank 210 is connected to the skin-proximal layer 110. When the waist belt body 10 is worn on the area to be massaged, the skin-proximal layer 110 applies force to the negative pressure tank 210, causing the suction port K3 of the flexible edge 220 to adhere closely to the area to be massaged. In other words, the skin-proximal layer 110 can press the flexible edge 220 against the area to be massaged via the negative pressure tank 210. With this arrangement, the skin-proximal layer 110 and the skin-distal layer 120 can exert dual force on the negative pressure massage head 20. This prevents the negative pressure massage head 20 from moving backward relative to the area to be massaged after the negative pressure belt 100 is tightened on the area to be massaged, thereby ensuring a close and effective suction effect.

[0070] Please refer to Figure 4 The negative pressure massage head 20 further includes a flexible edge 220 for adsorbing the massaged area. The flexible edge 220 is connected to the negative pressure tank 210. The center distance H1 between two adjacent flexible edges 220 is greater than or equal to the sum of the maximum radii R of the two adjacent flexible edges 220, so that the two adjacent flexible edges 220 do not interfere with each other.

[0071] Specifically, each flexible edge 220 has a central axis L, and the extension direction of the central axis L is the relative direction of the proximal skin layer 110 and the distal skin layer 120. The distance between the central axes L of two adjacent flexible edges 220 is the above-mentioned center distance H1. Each flexible edge 220 has a maximum radius R, which is the radius of the projection formed by the flexible edge 220 along the extension direction of the central axis L. When the center distance H1 of two adjacent flexible edges 220 is equal to the sum of the maximum radii R of the two adjacent flexible edges 220, the projections formed by the two adjacent flexible edges 220 along the extension direction of the central axis L are just tangent. When the center distance H1 of two adjacent flexible edges 220 is greater than the sum of the maximum radii R of the two adjacent flexible edges 220, the projections formed by the two adjacent flexible edges 220 along the extension direction of the central axis L are spaced apart. It is understandable that, whether greater than or equal to, it can ensure that two adjacent flexible edges 220 do not interfere with each other to avoid overlapping and air leakage of the flexible edges 220, thereby ensuring that each flexible edge 220 can be reliably adsorbed on the part to be massaged.

[0072] Please refer to Figure 8 The belt body 10 includes a skin-proximal layer 110 and a skin-distal layer 120 disposed opposite each other. The air receiving assembly 30 is disposed between the skin-proximal layer 110 and the skin-distal layer 120. When the belt body 10 is subjected to tension in the extension direction F1, the skin-proximal layer 110 in the middle region A2 is confined to the air receiving assembly 30, and the skin-proximal layer 110 in the installation region A1 is tilted relative to the skin-proximal layer 110 in the middle region A2 toward the skin-distal layer 120, thereby tilting the negative pressure massage head 20 in the installation region A1.

[0073] Specifically, when the belt body 10 is tensioned in the extension direction F1, the skin-near layer 110 and the skin-distal layer 120 in the middle region A2 maintain their original distance due to the restriction of the air receiving assembly 30, while the skin-near layer 110 and the skin-distal layer 120 in the mounting region A1 are brought closer due to the tension, causing the skin-near layer 110 in the mounting region A1 to bend relative to the skin-near layer 110 in the middle region A2. This in turn causes the negative pressure massage heads 20 to tilt along with the bending of the skin-near layer 110, and the bending directions of the negative pressure massage heads 20 on both sides of the air receiving assembly 30 are symmetrical. In this way, when the negative pressure belt 100 is worn around the waist, the negative pressure massage heads 20 on both sides of the air receiving assembly 30 can adapt to the tilt angle of the skin contours on both sides of the human back spine, which helps ensure that the negative pressure massage heads 20 have a good fit with the human body and facilitates the formation of negative pressure.

[0074] Please refer to Figure 5The at least two negative pressure massage heads 20 are disposed on opposite sides of the air receiving assembly 30 along the length of the waist belt body 10. In the lengthwise direction, the minimum spacing between a negative pressure massage head 20 in one mounting area A1 and at least one negative pressure massage head 20 in another mounting area A1 is between 80 mm and 100 mm. In other words, the minimum spacing H2 satisfies the relationship: 80 mm ≤ H2 ≤ 100 mm. This minimum spacing H2 can be, but is not limited to, 80 mm, 82 mm, 85 mm, 88 mm, 90 mm, 92 mm, 95 mm, 98 mm, or 100 mm, etc.

[0075] Limiting the minimum spacing H2 to 80mm to 100mm prevents the spacing between the two negative pressure massage heads 20 from being too large or too small. If the spacing between the two negative pressure massage heads 20 is too small, the two negative pressure massage heads 20 will be too close to the inclined, concave areas on either side of the user's spine, resulting in reduced skin contact between the negative pressure massage heads 20. If the spacing between the two negative pressure massage heads 20 is too large, the two negative pressure massage heads 20 will be too close to the user's flanks, also affecting their skin contact. Therefore, in this embodiment, limiting the spacing between the negative pressure massage heads 20 and the negative pressure massage heads 20 to a range of 80mm to 100mm (inclusive) ensures that the two negative pressure massage heads 20 are approximately located at the lower back (not the inclined, concave areas) on either side of the user's spine. This facilitates adequate skin contact between the negative pressure massage heads 20 and the user's skin, and facilitates negative pressure massage. It should be understood that in other embodiments, the arrangement of multiple negative pressure massage heads 20 should not be limited to the arrangement described in the above embodiment.

[0076] For example, multiple negative pressure massage heads 20 can be evenly distributed on the belt body 10. For example, four negative pressure massage heads 20 can be roughly arranged according to the four corners of a square or a rectangle; for another example, multiple negative pressure massage heads 20 can be divided into two groups, and the two groups of negative pressure massage heads 20 are spaced along the extension direction F1 of the belt body 10, presenting an eight-shaped symmetrical arrangement; for another example, multiple negative pressure massage heads 20 can be arranged at equal intervals according to a predetermined circumference, or arranged in an array, etc. In these exemplified arrangements, there are two adjacent negative pressure massage heads 20 among the multiple negative pressure massage heads 20 that have the above-mentioned shortest path along the extension direction F1 of the belt body 10.

[0077] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application, and these improvements and modifications are also considered to be within the scope of protection of the present application.
