[0005] The contents of the above-mentioned prior applications are incorporated into the present application by reference. Technical Field

[0006] The present application relates to the technical field of massage equipment, and in particular to a negative pressure belt. Background Art

[0007] With the development of technology, in daily work, study or leisure and entertainment activities, people often experience discomfort in the muscles or bones of the body due to maintaining an improper posture for a long time, and in severe cases, even develop diseases, thus affecting people's normal life. In order to relieve the discomfort in the muscles or bones, various types of massage devices are provided in the related art, such as negative pressure belts, which use negative pressure to absorb on the user's massaged part. However, the negative pressure absorption effect of the negative pressure belts provided in the related art is unstable. Utility Model Content

[0008] The present application provides a negative pressure belt that can form a stable negative pressure adsorption effect.

[0009] The negative pressure belt comprises a belt body and a negative pressure massage head;

[0010] The waist belt body is used to be worn on the part to be massaged, and the waist belt body has a skin-proximal side and a skin-distal side which are separated from each other;

[0011] The negative pressure massage head is connected to the belt body, and the negative pressure massage head includes:

[0012] A negative pressure tank, the negative pressure tank is connected to the waist belt body, the negative pressure tank comprises a tank body and a supporting rib, the tank body has a tank opening, the supporting rib surrounds the tank opening and is connected to the tank body; and

[0013] A flexible surrounding edge, the flexible surrounding edge is arranged around the can mouth to form a suction port, the suction port is exposed on the skin-proximal side, the flexible surrounding edge is located on the side of the supporting rib away from the skin-distal side, and the orthographic projection of the flexible surrounding edge in the direction from the skin-proximal side to the skin-distal side is at least partially located on the supporting rib;

[0014] When the negative pressure belt is worn on the part to be massaged, the supporting rib is used to provide support to the flexible rim when the flexible rim is compressed and deformed from the skin-proximal side toward the skin-distal side, so that the flexible rim fits the part to be massaged and the suction port self-adsorbs on the part to be massaged.

[0015] Wherein, when the flexible surrounding edge is in a free state, at least 1 / 2 of the flexible surrounding edge has a positive projection in the direction from the proximal side of the skin toward the distal side of the skin located on the supporting rib.

[0016] The waist belt body comprises a skin-near layer and a skin-distal layer which are arranged opposite to each other, the negative pressure tank is at least partially located between the skin-near layer and the skin-distal layer, the skin-near layer is provided with a mounting hole, the supporting rib is arranged around the mounting hole, and the flexible surrounding edge at least partially extends out of the mounting hole;

[0017] When the flexible surrounding edge is acted upon by the near-skin layer in the direction toward the far-skin layer, it abuts against the supporting rib and covers the side of the supporting rib facing away from the near-skin layer, wherein the supporting rib is a hard part.

[0018] Among them, the end of the tank body away from the suction port forms a force-bearing end, and the force-bearing end abuts against the distal skin layer. When the belt body is worn on the part to be massaged, the distal skin layer applies force to the force-bearing end to make the flexible surrounding edge close to the part to be massaged.

[0019] The supporting rib is fixedly connected to the skin-closed layer. When the belt body is worn on a part to be massaged, the skin-closed layer applies force to the supporting rib so that the flexible surrounding rib is tightly attached to the part to be massaged.

[0020] The outer diameter of the flexible edge gradually increases along the direction from the distal skin layer to the proximal skin layer, so that one end of the flexible edge away from the belt body forms a large diameter end, and the other end opposite to it is a small diameter end, so as to facilitate the compression deformation of the flexible edge to form adsorption, wherein the supporting rim is located on the deformation path of the large diameter end.

[0021] Among them, the flexible surrounding edge includes a base edge and a fitting edge, the base edge is connected to the supporting rib, one end of the fitting edge is connected to the base edge, the other end of the fitting edge is a free end, and the fitting edge extends obliquely from the base edge in a direction away from the negative pressure tank. When the fitting edge is squeezed, the fitting edge and the base edge are abutted against each other to form an overlapping state.

[0022] Wherein, the flexible surrounding edge has an inner periphery surrounding the tank mouth, the supporting rib has an inner edge surrounding the tank mouth, the inner periphery is flush with the inner edge, or the inner periphery protrudes from the inner edge along the radial direction of the tank mouth.

[0023] Wherein, the negative pressure belt includes at least two negative pressure massage heads, and the center distance between two adjacent negative pressure massage heads is greater than or equal to the sum of the maximum radii of the two adjacent negative pressure massage heads, so that the two adjacent flexible edges do not interfere with each other.

[0024] Among them, the belt body has two installation areas, the arrangement direction of the two installation areas is the extension direction of the belt body, each installation area is provided with at least one negative pressure massage head, the negative pressure belt also includes a control box, the control box is connected to the belt body and is arranged between the two installation areas, the control box has a hard structure, and the hard structure is used to hinder the deformation transfer between the two installation areas.

[0025] Wherein, the belt body also has a middle area, which is located between the two installation areas, and the belt body includes a near-skin layer and a far-skin layer that are relatively arranged, and the control box is arranged between the near-skin layer and the far-skin layer and is located in the middle area. When the belt body is tensioned in the extension direction, the near-skin layer located in the middle area is limited to the control box, and the near-skin layer located in the installation area is inclined relative to the near-skin layer located in the middle area toward the direction of the far-skin layer, so that the negative pressure massage head located in the installation area is inclined.

[0026] In the negative pressure belt provided by the present application, since the positive projection of the flexible surrounding edge in the direction from the skin-proximal side to the skin-distal side is at least partially located within the range of the supporting rib, when the user wears the belt body on the part to be massaged, the supporting rib can serve as a supporting basis to resist the flexible surrounding edge, which can not only prevent the flexible surrounding edge from turning outward and causing the negative pressure tank to initially form a small negative pressure, thereby allowing the negative pressure massage head to self-absorb on the part to be massaged, but also facilitate the flexible surrounding edge to fully fit with the part to be massaged, thereby forming a stable adsorption effect.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] Reference to "embodiment" or "implementation" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment or implementation may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0043] Please refer to Figure 1 and Figure 2 The present application provides a negative pressure belt 100, which is used to massage a part to be massaged. The part to be massaged is a human body, which can be, but is not limited to, the neck, arms, legs, waist, back, etc. of the human body. The subsequent content of the present application is explained by taking the waist as an example of the part to be massaged. It can be understood that these examples should not be understood as limiting the implementation methods of the present application.

[0044] The negative pressure belt 100 comprises a belt body 10 and a negative pressure massage head 20, and the negative pressure massage head 20 is connected to the belt body 10. The belt body 10 and the negative pressure massage head 20 are described in detail below with reference to the accompanying drawings.

[0045] The belt body 10 is a component 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 In this state, the belt body 10 can be flattened and stretched to form 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. Figure 2 As shown), in this state, the belt body 10 is wrapped into a roughly closed-loop annular structure, which defines a wearing space K9, and the wearing space K9 is used to accommodate the area to be massaged, that is, the user can wrap the belt body 10 around his or her waist.

[0046] Please refer to Figure 2 The belt body 10 has a skin-near side C1 and a skin-distal side C2 that are separated from each other. The skin-near side C1 is located on the side of the belt body 10 facing the wearing space K9, or in other words, the skin-near side C1 is the side of the belt body 10 that is relatively close to the user when the user wears the negative pressure belt 100. The skin-distal side C2 is located on the side of the belt body 10 that is away from the wearing space K9, or in other words, the skin-distal side C2 is the side of the belt body 10 that is away from the user when the user wears the negative pressure belt 100.

[0047] The negative pressure massage head 20 is a device that can be adsorbed on the massaged part by negative pressure and massage the massaged part. Negative pressure refers to a gas pressure state lower than normal pressure (i.e., one atmospheric pressure). In other words, the negative pressure massage head 20 can form a negative pressure effect. Under the action of the external atmospheric pressure, the negative pressure massage head 20 will be "pressed" on the massaged part, that is, the negative pressure massage head 20 appears to be "adsorbed" on the massaged part.

[0048] Please refer to Figure 3 and Figure 4 , the negative pressure massage head 20 includes: a negative pressure tank 210. The negative pressure tank 210 is connected to the waist belt body 10. The negative pressure tank 210 includes a tank body 211 and a supporting rib 212. Among them, the tank body 211 is a shell made of hard material, and the hard material can be hard plastic, hard resin or organic glass and other materials. The tank body 211 has a tank mouth K1 and a negative pressure cavity K2, and the tank mouth K1 is connected to the negative pressure cavity K2. The shape of the tank mouth K1 can be but not limited to circular, triangular, elliptical, etc. The supporting rib 212 surrounds (partially surrounds or fully surrounds) the tank mouth K1 and is connected to the tank body 211.

[0049] The negative pressure massage head 20 also includes: a flexible edging 220. The flexible edging 220 is a edging made of a flexible material, which can be deformed under a certain pressure. The material of the flexible edging 220 may include materials such as rubber or silicone. The flexible edging 220 is arranged around the tank opening K1 to form a suction port K3. The suction port K3 is exposed to the proximal side C1, and the suction port K3 is connected to the tank opening K1. The flexible edging 220 is located on the side of the support rib 212 away from the distal side C2. The orthographic projection of the flexible edging 220 in the direction from the proximal side C1 to the distal side C2 is at least partially located on the support rib 212.

[0050] When the negative pressure belt 100 is worn on the part to be massaged, the supporting rib 212 is used to provide support to the flexible rim 220 when the flexible rim 220 is compressed and deformed from the skin-proximal side C1 toward the skin-distal side C2, so that the flexible rim 220 fits the part to be massaged and the suction port K3 self-adsorbs on the part to be massaged.

[0051] Please refer to Figure 4 It is understandable that, in the process of pressing the flexible surrounding edge 220 on the massaged part, the flexible surrounding edge 220 may be "everted", and the so-called "everted" refers to the process of the flexible surrounding edge 220 being interchanged inside and outside, that is, the inner wall surface M1 of the flexible surrounding edge 220 is exposed to the outside world after everting, and the outer wall surface M2 of the flexible surrounding edge 220 is away from the outside world after everting. "Everting" is not conducive to the bonding and adsorption process of the flexible surrounding edge 220, so it is avoided as much as possible.

[0052] In this embodiment, when the user needs to use the negative pressure belt 100 for massage, the negative pressure massage head 20 can be firstly aligned with the part to be massaged, and then fixed to the part to be massaged through the belt body 10. During the wearing process, one end of the flexible edge 220 directly abuts against the part to be massaged. Since the positive projection of the flexible edge 220 in the direction from the skin-proximal side C1 to the skin-distal side C2 is at least partially located within the range of the support rib 212, the other end of the flexible edge 220 will abut against the support rib 212. Under the joint extrusion of the part to be massaged and the support rib 212, the flexible edge 220 generates compression deformation in the relative directions of the skin-proximal side C1 and the skin-distal side C2. The deformation will cause at least part of the air in the flexible edge 220 to be discharged to the outside through the suction port K3, thereby initially forming a small negative pressure inside the negative pressure tank 210, and adsorbing on the part to be massaged through the suction port K3, so that the negative pressure massage head 20 can achieve self-priming positioning at the part to be massaged. After the self-priming positioning is successful, the air in the negative pressure tank 210 can be extracted by a negative pressure device (such as an air pump) to further reduce the air pressure, so that the negative pressure massage head 20 can be more stably adsorbed on the massaged part. It can be understood that in the above process, the supporting rib 212 can prevent the flexible surrounding edge 220 from deforming and moving in the direction from the skin-proximal side C1 to the skin-distal side C2, thereby avoiding the problem of "externalization" of the flexible surrounding edge 220.

[0053] In summary, in the negative pressure belt 100 provided by the present application, since the positive projection of the flexible edge 220 in the direction from the skin-proximal side C1 to the skin-distal side C2 is at least partially located within the range of the supporting rib 212, when the user wears it on the part to be massaged through the belt body 10, the supporting rib 212 can serve as a supporting basis to resist the flexible edge 220, which can not only prevent the flexible edge 220 from turning outward and causing the negative pressure tank 210 to initially form a small negative pressure, thereby allowing the negative pressure massage head 20 to self-absorb on the part to be massaged, but also facilitate the flexible edge 220 to fully fit with the part to be massaged, thereby forming a stable adsorption effect.

[0054] Optionally, when the flexible surrounding edge 220 is in a free state (i.e., the state in which the flexible surrounding edge 220 is not acted upon by an external force), at least 1 / 2 (specifically, it may be 3 / 4, or 3 / 5, or 4 / 5, or 4 / 7, or 5 / 7, or 6 / 7, or any ratio greater than or equal to 1 / 2) of the orthographic projection of the flexible surrounding edge 220 in the direction from the skin-proximal side C1 toward the skin-distal side C2 is located on the supporting rib 212, or in other words, at least 1 / 2 of the orthographic projection of the flexible surrounding edge 220 on the supporting rib 212 falls on the supporting rib 212. With such a configuration, when the user wears the negative pressure belt 100 on the part to be massaged, at least 1 / 2 of the width of the flexible surrounding edge 220 abuts against the supporting rib 212, ensuring that the contact area between the supporting rib 212 and the flexible surrounding edge 220 is large enough, thereby preventing the flexible surrounding edge 220 from everting outward and ensuring that the flexible surrounding edge 220 is always in close contact with the part to be massaged.

[0055] Please refer to further Figure 5 , the belt body 10 includes a skin-near layer 110 and a skin-distal layer 120 that are arranged relatively to each other. The skin-near layer 110 refers to a material layer located on the side of the belt body 10 facing the wearing space K9, or in other words, the skin-near layer 110 is a material layer on the side of the belt body 10 that is relatively close to the user when the user wears the negative pressure belt 100. The skin-distal layer 120 refers to a material layer located on the side of the belt body 10 that is away from the wearing space K9, or in other words, the skin-distal layer 120 is a material layer on the side of the belt body 10 that is away from the user when the user wears the negative pressure belt 100.

[0056] The edge portions of the skin-near layer 110 and the skin-distal layer 120 are attached and connected, and a receiving space K4 is formed between the skin-near layer 110 and the skin-distal layer 120. The negative pressure tank 210 is at least partially located between the skin-near layer 110 and the skin-distal layer 120, that is, at least part of the negative pressure tank 210 is disposed in the receiving space K4.

[0057] In one embodiment, the negative pressure tank 210 is only partially located in the accommodation space K4. Figure 5 and Figure 6 In another embodiment, the negative pressure tank 210 is completely disposed in the accommodation space K4. Figure 7 and Figure 8 The following contents of this application are Figure 5 The structure shown is used as a basis for explanation.

[0058] Please refer to Figure 4 and Figure 5The skin-near layer 110 is provided with a mounting hole K5, and the mounting hole K5 is connected to the accommodating space K4. The shape of the mounting hole K5 can be, but is not limited to, circular, elliptical, etc. The supporting rib 212 is arranged around the mounting hole K5. The flexible surrounding edge 220 at least partially extends out of the mounting hole K5 to be exposed to the outside world, and the flexible surrounding edge 220 is arranged on the side of the supporting rib 212 away from the skin-near layer 120.

[0059] In one embodiment, the support rib 212 is disposed on the side of the near-skin layer 110 away from the far-skin layer 120. Figure 5 and Figure 6 In another embodiment, the support rib 212 is disposed on a side of the proximal skin layer 110 close to the distal skin layer 120, as shown in FIG. Figure 7 and Figure 8 The following contents of this application are Figure 5 The structure shown is used as a basis for explanation.

[0060] Please refer to Figure 5 , when the flexible edge 220 is acted upon by the skin-near layer 110 in the direction toward the skin-distal layer 120, it abuts against the supporting rib 212 and covers the side of the supporting rib 212 away from the skin-near layer 110. That is to say, when the negative pressure massage head 20 is attached to the part to be massaged, the part to be massaged presses the flexible edge 220 in the direction from the skin-near layer 110 to the skin-distal layer 120, so that the flexible edge 220 further abuts against the side of the supporting rib 212 away from the skin-near side C1. The supporting rib 212 is a hard part, and its material can be, but is not limited to, at least one of hard materials such as hard plastic, hard resin or organic glass.

[0061] Regarding the arrangement of this embodiment, on the one hand, the support rib 212 can prevent the suction port K3 from excessively moving backward relative to the mounting hole K5, thereby preventing the waist belt body 10 from blocking the suction port K3. On the other hand, when the part to be massaged abuts against the flexible rim 220, the support rib 212 as a hard part will not be significantly deformed due to the abutment, thereby preventing the flexible rim 220 from excessively moving along the near-skin side C1 toward the far-skin layer 120. In other words, the support rib 212 plays a role of hard limit, preventing the flexible rim 220 from everting. On the other hand, the flexible rim 220 can separate the support rib 212 from the part to be massaged as much as possible to avoid hard contact.

[0062] It should be noted that, in this embodiment, when the flexible edge 220 is acted on in the direction from the near skin layer 110 to the far skin layer 120, the flexible edge 220 may directly abut against the supporting rib 212, or may indirectly abut against the supporting rib 212. The so-called direct abutment refers to the abutment form in which the flexible edge 220 is in direct contact with the supporting rib 212; the so-called indirect abutment refers to the abutment form in which the flexible edge 220 is not in direct contact with the supporting rib 212, that is, the flexible edge 220 indirectly abuts against the supporting rib 212 through other objects.

[0063] Please refer to Figure 4 and Figure 5 , the end of the tank body 211 away from the suction port K3 forms a force-bearing end 2111, which is the tail of the tank body 211. The force-bearing end 2111 is in contact with the distal skin layer 120. When the belt body 10 is worn on the part to be massaged, the distal skin 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 distal skin 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 to the part to be massaged, otherwise it will be 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 tightened state tends to reduce the wearing space K9. Since the force-bearing end 2111 of the tank body 211 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 to the force-bearing end 2111, so that the flexible surrounding 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.

[0064] 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 easy to deform under force, so it can be ensured 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, reduce the backward movement of the negative pressure massage head 20, so as to improve the stability of the flexible surrounding edge 220 after contacting the skin, which is conducive to the flexible surrounding edge 220 and the skin Fully and stably fit.

[0065] Please refer to Figure 4 and Figure 5 , the support rib 212 is fixedly connected to the skin-proximal layer 110, and when the waist belt body 10 is worn on the part to be massaged, the skin-proximal layer 110 applies force to the support rib 212 so that the flexible surrounding edge 220 is closely attached to the part to be massaged. In other words, the skin-proximal layer 110 can press the flexible surrounding edge 220 against the part to be massaged through the support rib 212. With such a configuration, the skin-proximal layer 110 and the skin-distal layer 120 can apply double force to the negative pressure massage head 20, so that after the negative pressure waist belt 100 is tied tightly to the part to be massaged, the negative pressure massage head 20 is not easy to move backward relative to the part to be massaged, thereby ensuring the fitting and adsorption effect.

[0066] Please refer to Figure 4 and Figure 5 The outer diameter of the flexible edge 220 gradually increases along the direction from the far skin layer 120 to the near skin layer 110, so that the end of the flexible edge 220 away from the waistband body 10 forms a large diameter end D2, and the other end opposite to the waistband body 10 forms a small diameter end D1, so as to facilitate the compression deformation of the flexible edge 220 to form adsorption. The supporting rib 212 is located on the deformation path of the large diameter end D2.

[0067] Specifically, the large diameter end D2 is the end with the largest diameter of the flexible surrounding edge 220, and the large diameter end D2 has a suction port K3 for adsorbing the part to be massaged. The small diameter end D1 is the end with the smallest diameter of the flexible surrounding edge 220. The outer diameter of the flexible surrounding edge 220 gradually increases from the small diameter end D1 to the large diameter end D2, and the supporting rib 212 is located on the deformation path of the large diameter end D2. With such a configuration, on the one hand, it is convenient for the flexible surrounding edge 220 to be compressed from the large diameter end D2 to the small diameter end D1 and abut against the supporting rib 212; on the other hand, since the outer diameter of the large diameter end D2 is the largest, the suction port K3 located at the large diameter end D2 can be set larger, so that the suction port K3 can adsorb more parts to be massaged, thereby improving the stability of negative pressure adsorption.

[0068] Please refer to Figure 4 and Figure 5The flexible surrounding edge 220 includes a base edge 221 and a fitting edge 222. The base edge 221 is connected to the supporting rib 212, and the connection method between the two can be but is not limited to bonding. The base edge 221 is annular and surrounds the mounting hole K5, and the base edge 221 and the supporting rib 212 are superimposed together. One end of the fitting edge 222 is connected to the base edge 221, and the other end of the fitting edge 222 is a free end, and the fitting edge 222 extends obliquely from the base edge 221 in a direction away from the negative pressure tank 210, that is, the inner diameter of the fitting edge 222 gradually increases in a direction away from the negative pressure tank 210, thereby forming a roughly trumpet-shaped structure, or a funnel-shaped structure. Moreover, in the direction from the skin-proximal side C1 to the skin-distal side C2, the orthographic projection of the fitting edge 222 on the base edge 221 at least partially falls within the range of the base edge 221, so that when the fitting edge 222 is squeezed, the fitting edge 222 and the base edge 221 are abutted against each other to form an overlapping state. With such a configuration, in the initial stage of wearing, the fitting edge 222 is squeezed by the part to be massaged and compressed, thereby achieving primary fitting with the part to be massaged; after further force is applied, the fitting edge 222 can be abutted against the base edge 221, and the fitting edge 222 and the base edge 221 are overlapped, and the dual effects ensure the fitting degree.

[0069] Optionally, the base edge 221 is made of an elastic material, so that the base edge 221 is elastic in the relative directions of the near-skin layer 110 and the far-skin layer 120. In this way, the base edge 221 can be elastically abutted against the fitting edge 222 to make the fitting edge 222 fit the human body better, and the fitting effect felt by the massaged part can be "softer", thereby improving the wearing comfort.

[0070] Please refer to Figure 4 and Figure 5 The flexible rim 220 has an inner circumference S1 surrounding the tank opening K1. The support rib 212 has an inner edge S2 surrounding the tank opening K1. The inner circumference S1 is an edge of the flexible rim 220 adjacent to the support rib 212. The inner circumference S1 is flush with the inner edge S2, or the inner circumference S1 protrudes from the inner edge S2 along the radial direction of the tank opening K1.

[0071] It is understandable that during the adsorption massage, the user's skin may enter the flexible rim 220, and then may touch the supporting rib 212 and the tank body 211 of the negative pressure tank 210, causing discomfort to the user. In this embodiment, the inner periphery S1 is flush with or protrudes from the inner edge S2. It can be understood that the diameter of the inner periphery S1 is less than or equal to the diameter of the inner edge S2, so that the inner edge S2 is completely covered by the flexible rim 220 in the relative direction of the near-skin layer 110 and the far-skin side C2. In this way, the user's skin is not easy to contact the supporting rim 212 and the tank body 211 of the negative pressure tank 210, thereby reducing the probability of hard contact between the skin and the negative pressure tank 210, and improving the user's massage experience.

[0072] Please refer to further Fig. 9 The negative pressure belt 100 includes at least two negative pressure massage heads 20, and the specific number can be, but is not limited to, 3, 4, 5, 6, etc. It should be noted that the specifications of the negative pressure massage heads 20 can be the same, or different, or partly the same and partly different. The center distance H1 between two adjacent negative pressure massage heads 20 is greater than or equal to the sum of the maximum radii R of the two adjacent negative pressure massage heads 20, so that the flexible surrounding edges 220 of the two adjacent negative pressure massage heads 20 do not interfere with each other.

[0073] Specifically, each negative pressure massage head 20 has a central axis L, and the extension direction of the central axis L is the relative direction of the skin-proximal side C1 and the skin-distal side C2. The distance between the central axes L of two adjacent negative pressure massage heads 20 is the above-mentioned center distance H1. Each negative pressure massage head 20 has a maximum radius R, which is the radius of the projection formed by the negative pressure massage head 20 along the extension direction of the central axis L. When the center distance H1 of two adjacent negative pressure massage heads 20 is equal to the sum of the maximum radii R of the two adjacent negative pressure massage heads 20, the projections formed by the two adjacent negative pressure massage heads 20 along the extension direction of the central axis L are just tangent. When the center distance H1 of two adjacent negative pressure massage heads 20 is greater than the sum of the maximum radii R of the two adjacent negative pressure massage heads 20, the projections formed by the two adjacent negative pressure massage heads 20 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 the flexible edges 220 of two adjacent negative pressure massage heads 20 do not interfere with each other, avoid overlapping and air leakage of the flexible edges 220, and ensure that each negative pressure massage head 20 can be reliably adsorbed on the massage area.

[0074] Please refer to further Fig. 9 and Fig.10The belt body 10 has two installation areas A1, and the arrangement direction of the two installation areas is the extension direction F1 of the belt body 10. Each installation area A1 is provided with at least one negative pressure massage head 20, and the specific number can be but not limited to 1, 2, 3, 4, etc. The negative pressure belt 100 also includes a control box 320, which is connected to the belt body 10 and is arranged between the two installation areas A1. The control box 320 has a hard structure, and the hard structure is used to hinder the deformation transmission between the two installation areas A1.

[0075] It is understandable that in most cases, the area to be massaged is not flat, such as the waist. From the left side to the right side (or the right side to the left side) of the human body, the back of the human body shows an undulating trend. When the negative pressure belt 100 is worn on the waist, in order to ensure that the negative pressure massage heads 20 are well adsorbed, each negative pressure massage head 20 needs to adjust its angle to adapt to the trend of the back. However, each negative pressure massage head 20 will generate a force during the movement, which will be transmitted to each other through the belt body 10, which can easily affect the adsorption stability of each. As a result, it is difficult for the negative pressure massage head 20 to stably fit with the area to be massaged, resulting in a poor user experience.

[0076] In this embodiment, a control box 320 is provided on the belt body 10, and at least part of the control box 320 is a hard structure. Here, the so-called "hard" means that it is not easy to deform relative to the belt body 10, and the hard structure is the part of the control box 320 with a harder texture. Of course, in some embodiments, the entire control box 320 can be a hard structure. 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 another negative pressure massage head 20, so that each negative pressure massage head 20 is adsorbed independently without interfering with each other.

[0077] Please refer to Fig.10 and Fig.11, the belt body 10 also has a middle area A2, and the middle area A2 is located between the two installation areas A1. The belt body 10 includes a near-skin layer 110 and a far-skin layer 120 that are arranged opposite to each other, and the control box 320 is arranged between the near-skin layer 110 and the far-skin layer 120 and is located in the middle area A2. When the belt body 10 is tensioned in the extension direction F1, the near-skin layer 110 located in the middle area A2 is limited to the control box 320, and the near-skin layer 110 located in the installation area A1 is inclined relative to the near-skin layer 110 located in the middle area A2 toward the direction of the far-skin layer 120, so that the negative pressure massage head 20 located in the installation area A1 is inclined, as shown in FIG. Fig.11 shown.

[0078] 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 area A2 maintain their original distance due to the restriction of the control box 320, while the skin-near layer 110 and the skin-distal layer 120 in the installation area A1 will be brought together due to the tension, thereby causing the skin-near layer 110 in the installation area A1 to bend compared to the skin-near layer 110 in the middle area A2, thereby causing the negative pressure massage head 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 control box 320 are symmetrical. In this way, when the negative pressure belt 100 is worn on the waist, the negative pressure massage heads 20 on both sides of the control box 320 can adapt to the inclination angle of the skin contour on both sides of the back spine of the human body, which is conducive to ensuring that the negative pressure massage heads 20 have a good fit with the human body and is conducive to the formation of negative pressure.

[0079] Please refer to Fig.10 , the at least two groups of negative pressure massage heads 20 are respectively arranged on opposite sides of the air receiving assembly 30 along the length direction of the waist belt body 10, and in the length direction, the minimum spacing between the negative pressure massage head 20 located in one installation area A1 and at least one negative pressure massage head 20 located in another installation area A1 satisfies 80mm to 100mm. In other words, the minimum spacing H2 satisfies the relationship: 80mm≤H2≤100mm. The minimum spacing distance H2 can be, but is not limited to, 80mm, or 82mm, or 85mm, or 88mm, or 90mm, or 92mm, or 95mm, or 98mm, or 100mm, etc.

[0080] By limiting the minimum spacing H2 to 80mm to 100mm, the spacing between the two negative pressure massage heads 20 can be prevented 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 parts on both sides of the user's spine, resulting in a decrease in the fit between the negative pressure massage heads 20 and the skin. 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 side waist position of the user, which will also affect the fit between the negative pressure massage heads 20 and the user's skin. Therefore, in this embodiment, the spacing between the negative pressure massage heads 20 and the negative pressure massage heads 20 is limited to the range of 80mm to 100mm (including the endpoints), which can ensure that the two negative pressure massage heads 20 are roughly located at the back waist position (non-inclined concave parts) on both sides of the user's spine, which is conducive to the full fit between the negative pressure massage heads 20 and the user's skin and the 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 scheme described in the above embodiment.

[0081] 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 circle, 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.

[0082] 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 the field can change, modify, replace and modify the above embodiments within the scope of the present application, and these improvements and modifications are also regarded as the scope of protection of the present application.
