When the resisting structure is against the floating seat or the electrode massage member, the surrounding wall of the floating seat does not block the connecting hole, so that the connecting hole maintains the connection between the outer chamber and the inner chamber.

[0012] Wherein, the peripheral wall of the floating seat includes a plurality of connecting parts, and the plurality of connecting parts are connected in sequence to form wrinkles, and an angle is formed between two adjacent connecting parts.

When the resisting structure abuts against the floating seat or the electrode massage part, the two connecting parts are not overlapped to form a gap, and the gap connects the outer chamber and the connecting hole.

[0013] When the floating seat floats downward, the size of the outer wall of the floating seat expands toward the elastic surrounding edge.

A connecting hole is provided on the floating electrode, which connects the inner chamber and the outer chamber together, and a height difference is formed between the connecting hole and the bottom wall of the outer chamber. The air pump is arranged in the inner chamber, and when the air pump works to suck air, the air pressure in the inner chamber decreases, and the air pressure in the outer chamber connected to the inner chamber through the connecting hole can also be reduced accordingly, thereby ensuring that the negative pressure massage head is stably adsorbed on the part to be massaged. It can be understood that since the air pump is arranged in the inner chamber, it can not only reduce the air pump from occupying other spaces, but also protect the air pump. In addition, when the floating electrode is squeezed by the part to be massaged and the air is compressed, it is also conducive to the pump to quickly suck air to form a negative pressure. At the same time, a height difference is formed between the connecting hole and the floating chamber, so that during negative pressure adsorption massage, sweat and other liquids sucked into the outer chamber flow into the bottom of the outer chamber, and will not easily enter the inner chamber from the connecting hole, thereby reducing the possibility of damage to the air pump caused by sweat and other liquids entering.

DETAILED DESCRIPTION

[0037] 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.

[0038] 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.

[0039] Please refer to Figures 1 to 3 The present application provides a massage device 100, which can be, but is not limited to, a cervical massager, a waist massager, a back massager, a foot massager, a leg massager, a shoulder massager, etc.

[0040] The massage device 100 includes a wearing mechanism 20 and a negative pressure massage head 10 described in any of the following embodiments, and the negative pressure massage head 10 is connected to the wearing mechanism 20. The wearing mechanism 20 has the functions of providing electric energy to the negative pressure massage head 10, controlling the negative pressure massage head 10 to perform massage, and the like. The negative pressure massage head 10 is used to be adsorbed on the part to be massaged by negative pressure, and output one or more of electric energy, thermal energy, mechanical energy, etc. to the part to be massaged, so as to achieve the effects of promoting blood circulation, relieving fatigue, relaxing the meridians, and dredge the collaterals, etc. The part to be massaged is a human body, which can be, but is not limited to, the head, neck, arms, legs, waist, back, etc. of the human body.

[0041] It should be noted that one massage device 100 may be provided with one or more negative pressure massage heads 10, and the specific number may be, but is not limited to, 1, 2, 3, etc. When a plurality of negative pressure massage heads 10 are provided, the specifications and structures of each negative pressure massage head 10 may be the same or different.

[0042] Optionally, the massage device 100 further includes a harness 30, and opposite ends of the harness 30 are respectively connected to the wearing mechanism 20 and the negative pressure massage head 10, so that the negative pressure massage head 10 is electrically connected to the wearing mechanism 20. The harness 30 may have a certain flexibility, so that the massage head can move in the space around the wearing mechanism 20 by means of the flexible harness 30, and massage the part to be massaged within a certain range from the wearing mechanism 20, so that the negative pressure massage head 10 can flexibly massage multiple positions.

[0043] In one embodiment, the wiring harness 30 can be fixedly connected to the wearing mechanism 20, that is, the wiring harness 30 and the wearing mechanism 20 are inseparable. In another embodiment, the wiring harness 30 can also be fixedly connected to the negative pressure massage head 10, that is, the wiring harness 30 and the negative pressure massage head 10 are inseparable. In yet another embodiment, the wiring harness 30 is simultaneously and inseparablely connected to the wearing mechanism 20 and the negative pressure massage head 10. In yet another embodiment, the wiring harness 30 is simultaneously and detachably connected to the wearing mechanism 20 and the negative pressure massage head 10, so that it is convenient to disassemble and repair, or replace the negative pressure massage head 10 of different specifications. The detachable connection method can be realized by a connector. Taking the negative pressure massage head 10 as an example, a female connector (i.e., a socket) is provided on the negative pressure massage head 10, and a male connector (i.e., a plug) is provided on the wiring harness 30. The male connector can be inserted into the female connector to achieve electrical connection.

[0044] Optionally, the wearing mechanism 20 includes a massage module 210 and two elastic clamping arms 220, the two elastic clamping arms 220 are respectively bent and connected to the opposite ends of the massage module 210, and the massage module 210 and the two elastic clamping arms 220 together form a U-shaped structure. Among them, the two elastic clamping arms 220 have a certain elastic force, so that the two elastic clamping arms 220 can be deformed to a certain extent, and have the ability to restore deformation. When the massage device 100 is worn on the part to be massaged, the two elastic clamping arms 220 can be deformed in a direction away from each other by an external force, so that enough space is opened between the two elastic clamping arms 220 to accommodate the part to be massaged (such as the neck). When the part to be massaged enters between the two elastic clamping arms 220, the cancellation of the external force acting on the two elastic clamping arms 220 can make the two elastic clamping arms 220 restore the deformation in a direction close to each other, so as to use the two elastic clamping arms 220 to clamp the part to be massaged.

[0045] The massage module 210 has a skin-near side C3 and a skin-back side C4 that are opposite to each other. When the massage device 100 is worn on a part to be massaged, the side of the massage module 210 close to the part to be massaged is the skin-near side C3, and the side of the massage module 210 away from the part to be massaged is the skin-back side C4.

[0046] The massage surface M1 of the massage module 210 is exposed from the skin-proximal side C3 of the massage module 210. The massage module 210 is used to output one or more of electrical energy, thermal energy, light energy, mechanical energy, etc. to the massaged part to massage the massaged part, thereby achieving the effects of promoting blood circulation, relieving fatigue, relaxing the meridians, etc.

[0047] Optionally, the wearing mechanism 20 may further include a receiving member 230, and the receiving member 230 is disposed on the back skin side C4 of the massage module 210. A receiving space K1 is provided on the side of the receiving member 230 away from the massage module 210, and the receiving space K1 can be detachably connected to the negative pressure massage head 10. When the massage device 100 is not needed, the negative pressure massage head 10 can be placed in the receiving space K1, and there is no need to provide an additional receiving device for the negative pressure massage head 10. In addition, the receiving space K1 is provided on the side of the receiving member 230 away from the massage module 210, and will not occupy the space on the near skin side C3. The massage module 210 can thus configure a larger massage surface M1 on the near skin side C3 to increase the contact area between the massage surface M1 and the human body.

[0048] Please refer to Figures 4 to 7 The present application provides a negative pressure massage head 10, which includes: an air pump assembly 110, an elastic rim 130, and a floating electrode 120. The air pump assembly 110 includes an air pump 111 and a pump mounting seat 112, and the air pump 111 is mounted on the pump mounting seat 112. The elastic rim 130 is arranged around the pump mounting seat 112 and forms a floating cavity Q. The elastic rim 130 has a negative pressure port K2, and the negative pressure port K2 is connected to the floating cavity Q. The floating electrode 120 is arranged in the floating cavity Q, and the floating electrode 120 includes a floating seat 121 and an electrode massage member 122. One end of the floating seat 121 is connected to the elastic rim 130 or the pump mounting seat 112, and the other end of the floating seat 121 is connected to the electrode massage member 122, so that the electrode massage member 122 floats in the floating cavity Q. The floating seat 121 and the pump mounting seat 112 together form an inner chamber Q1, and the air pump 111 is located in the inner chamber Q1. The floating seat 121 and the elastic surrounding edge 130 together form an outer chamber Q2. The floating seat 121 is provided with a connecting hole K4 (such as Figure 7 As shown in FIG. 1 , the connecting hole K4 connects the outer chamber Q2 and the inner chamber Q1, so that the air pump 111 forms a negative pressure on the outer chamber Q2. A height difference H5 is formed between the connecting hole K4 and the bottom wall M8 of the outer chamber Q2 to prevent the liquid sucked into the outer chamber Q2 from entering the inner chamber Q1 through the connecting hole K4. It should be noted that the "prevent" mentioned here does not mean "completely prevent", but means "reducing the possibility".

[0049] Specifically, the negative pressure massage head 10 provided in the present application refers to a device that can be adsorbed on the part to be massaged through negative pressure and massage the part to be massaged. Among them, negative pressure refers to a gas pressure state lower than normal pressure (that is, one atmospheric pressure commonly referred to). In other words, the negative pressure massage head 10 can form a negative pressure effect. Under the action of the external atmospheric pressure, the negative pressure massage head 10 will be "pressed" on the part to be massaged, that is, the negative pressure massage head 10 appears to be "adsorbed" on the part to be massaged. From the overall structure point of view, the negative pressure massage head 10 provided in the present application can be regarded as consisting of three parts: an air pump assembly 110, a floating electrode 120, and an elastic surrounding edge 130, which are described in detail below.

[0050] For the elastic rim 130: the elastic rim 130 can be regarded as a suction cup, which can be adsorbed on the part to be massaged by negative pressure. The elastic rim 130 is soft in texture, and its material can be but not limited to rubber, silicone, etc. When subjected to external force, the elastic rim 130 can produce elastic deformations such as bending, twisting, and compression. When the external force is removed or under the action of external force, the elastic rim 130 can return to its original shape. The first end D1 of the elastic rim 130 is connected to the periphery of the air pump assembly 110 in a surrounding manner, and the two are thus jointly surrounded to form a floating cavity Q with a certain spatial volume size. The end face of the second end D2 of the elastic rim 130 is a fitting portion M2 for fitting the part to be massaged. The fitting portion M2 is surrounded and surrounded to form a negative pressure port K2, which is connected to the floating cavity Q, or in other words, the negative pressure port K2 is an opening formed by the floating cavity Q on the elastic rim 130.

[0051] Regarding the floating electrode 120: the floating electrode 120 is arranged on one side of the air pump assembly 110 and is located in the floating cavity Q. The floating electrode 120 can be connected to the air pump assembly 110, or to the elastic surrounding edge 130, or to both the air pump assembly 110 and the elastic surrounding edge 130. In the floating electrode 120, the electrode massage member 122 is used to contact the part to be massaged to output electrical energy to the part to be massaged, so that the massage effect can be achieved through electrical stimulation. The floating seat 121 is elastic in the preset direction F and can be stretched or shortened, thereby driving the electrode massage member 122 to float up and down along the preset direction F. The "floating" means that the floating electrode 120 can move along the preset direction F in the floating cavity Q. Among them, the preset direction F is the relative direction of the floating electrode 120 and the air pump assembly 110.

[0052] When the floating electrode 120 is subjected to a force in the first preset direction F1, the floating seat 121 gradually shortens along the first preset direction F1, and this process is that the floating electrode 120 floats downward; when the force in the first preset direction F1 is removed, the floating seat 121 automatically extends along the second preset direction F2, and this process is that the floating electrode 120 floats upward. The first preset direction F1 is the direction of the floating electrode 120 toward the air pump assembly 110, and the second preset direction F2 is the opposite direction of the first preset direction F1.

[0053] When the negative pressure massage head 10 is adsorbed on the part to be massaged, the floating electrode 120 is squeezed between the air pump assembly 110 and the part to be massaged and is in a compressed state. Since the floating electrode 120 is elastic in the preset direction F, the floating electrode 120 has a tendency to stretch, thereby tightly contacting the part to be massaged. In this way, the floating electrode 120 and the part to be massaged have a high degree of fit, thereby achieving an ideal massage effect on the part to be massaged.

[0054] Since the floating electrode 120 is disposed in the floating chamber Q, the floating chamber Q is divided into two chambers, one of which is an inner chamber Q1 surrounded by the floating electrode 120 and the air pump assembly 110, and the other is an outer chamber Q2 surrounded by the floating electrode 120 and the elastic surrounding edge 130. The outer chamber Q2 is directly connected to the negative pressure port K2. In the case where the elastic surrounding edge 130 does not deform, when the floating electrode 120 floats downward, the inner chamber Q1 decreases and the outer chamber Q2 increases. Conversely, when the floating electrode 120 floats upward, the inner chamber Q1 increases and the outer chamber Q2 decreases.

[0055] A communication hole K4 is provided on the circumferential side wall of the floating seat 121, and the communication hole K4 penetrates the side wall of the floating seat 121, so that the inner chamber Q1 and the outer chamber Q2 are connected through the communication hole K4. The number of the communication holes K4 can be one or more, and the specific number can be but is not limited to 1, 2, 3, 4, 5, 6, etc. When the number of the communication holes K4 is multiple, the multiple communication holes K4 can be arranged at intervals along the circumference of the floating seat 121.

[0056] Regarding the air pump assembly 110: the air pump assembly 110 is mainly used to suck the air in the floating chamber Q so that the floating chamber Q is in a negative pressure state, thereby achieving adsorption on the part to be massaged. Specifically, the pump mounting seat 112 is an installation structure for bearing and protecting the air pump 111, and also serves to connect the elastic surrounding edge 130 and form the floating chamber Q. The connection between the pump mounting seat 112 and the air pump 111 can be a detachable connection or a non-detachable connection. The air pump 111 is arranged in the inner chamber Q1. When the air pump 111 sucks air, the air pressure of the inner chamber Q1 first decreases with the reduction of air, and the air in the outer chamber Q2 flows into the inner chamber Q1 through the connecting hole K4, and the air pressure of the outer chamber Q2 is then also reduced, which is finally reflected in the enhanced negative pressure adsorption effect of the negative pressure massage head 10 on the part to be massaged. The air pump 111 is arranged in the inner chamber Q1 formed by the floating seat 121, which can not only reduce the air pump 111 to occupy other space, but also protect the air pump 111. In addition, when the floating electrode 120 is squeezed by the massage area to compress the air, it is also beneficial for the pump to quickly suck air to form negative pressure.

[0057] In some cases, the user's neck may produce sweat, which will enter the outer chamber Q2 through the negative pressure port K2. Since the outer chamber Q2 is connected to the inner chamber Q1 through the connecting hole K4, the sweat may also enter the inner chamber Q1 from the connecting hole K4 and finally be sucked into the air pump 111. However, this may cause damage to the air pump 111. In the present application, there is a height difference H5 between the connecting hole K4 and the bottom wall M8 of the outer chamber Q2. The height difference H5 means that the distance between the connecting hole K4 and the bottom wall M8 of the outer chamber Q2 in the preset direction F is greater than zero. In other words, the connecting hole K4 is not set at the bottom position of the floating seat 121 close to the air pump 111. In this way, the sweat can only gather at the bottom of the outer chamber Q2 under the action of gravity, and will not reach the connecting hole K4. In addition, setting the connecting hole K4 away from the bottom wall M8 of the outer chamber Q2 can also increase the wall climbing length of the sweat, thereby reducing the possibility of sweat entering the connecting hole K4.

[0058] Optionally, the connecting hole K4 is disposed adjacent to the electrode massage member 122 relative to the bottom wall M8 of the floating chamber Q, that is, the distance between the electrode massage member 122 and the connecting hole K4 in the preset direction F is less than 1 / 2 of the size of the floating seat 121 in the preset direction F, or in other words, the height difference H5 between the connecting hole K4 and the bottom wall M8 of the outer chamber Q2 is greater than 1 / 2 of the size of the floating seat 121 in the preset direction F. Such an arrangement can effectively increase the height difference H5 between the connecting hole K4 and the bottom wall M8 of the outer chamber Q2, making it more difficult for the liquid sucked into the outer chamber Q2 to approach the connecting hole K4, thereby effectively preventing the liquid from being sucked into the air pump 111.

[0059] For the negative pressure massage head 10: When the negative pressure massage head 10 is needed to massage the part to be massaged, the negative pressure massage head 10 can be adsorbed on the part to be massaged in the following manner, but is not limited to it. Specifically, first, align the negative pressure massage head 10 with the part to be massaged, and then directly press the negative pressure massage head 10 on the part to be massaged, so that the fitting part M2 of the elastic surrounding edge 130 fits with the part to be massaged. In this process, the elastic surrounding edge 130 and the floating electrode 120 will be squeezed and deformed, and the deformation will cause at least part of the air in the floating cavity Q to be discharged to the outside, so that the floating cavity Q will initially form a negative pressure effect, and adsorbed on the part to be massaged through the negative pressure port K2, so that the negative pressure massage head 10 can achieve self-priming positioning on the part to be massaged. Furthermore, after the self-priming positioning is successful, the air pump 111 is used to extract the air in the inner chamber Q1, and the air pressure of the outer chamber Q2 is reduced accordingly, so that the air pressure of the floating cavity Q can be further reduced, so that the negative pressure massage head 10 can be more stably adsorbed on the part to be massaged.

[0060] Please refer to Figure 8 , the outer peripheral wall of the floating seat 121 is provided with a convex structure 1211 at least partially, and the convex structure 1211 is a structure convexly arranged in a direction away from the inner chamber Q1. The convex structure 1211 is at least partially located between the connecting hole K4 and the bottom wall M8 of the floating chamber Q. It can be understood that by providing the convex structure 1211 between the connecting hole K4 and the bottom wall M8 of the floating chamber Q, it is possible to increase the difficulty of the liquid flowing to the connecting hole K4, and further prevent the liquid from flowing to the connecting hole K4 and entering the inner chamber Q1.

[0061] In one embodiment, the floating seat 121 has a plurality of communication holes K4 and a plurality of convex structures 1211, and the convex structures 1211 are arranged one-to-one with the communication holes K4, that is, a corresponding convex structure 1211 is arranged between each communication hole K4 and the bottom wall M8 of the floating cavity Q. Such an arrangement can reduce the probability of liquid flowing into each communication hole K4.

[0062] In another embodiment, the convex structure 1211 is disposed around the circumference of the floating seat 121, that is, the convex structure 1211 surrounds the outer peripheral wall of the floating seat 121. In this way, the difficulty of the liquid flowing to the connecting hole K4 can be increased in the circumference of the floating seat 121, and even if the liquid flows along the outer peripheral wall of the floating seat 121 at an angle, it is difficult to flow through the connecting hole K4.

[0063] Please refer to Figure 6The pump mounting seat 112 includes a resisting structure 1123, which is disposed on a side of the air pump 111 facing the electrode massage member 122, and is used to stop the maximum compression stroke of the floating seat 121. When the resisting structure 1123 abuts against the floating seat 121 or the electrode massage member 122, the peripheral wall of the floating seat 121 does not block the communication hole K4, so that the communication hole K4 maintains the communication between the outer chamber Q2 and the inner chamber Q1.

[0064] Specifically, when the floating electrode 120 floats downward to a certain position, the floating seat 121 or the electrode massage member 122 will abut against the resisting structure 1123, and the resisting structure 1123 will prevent the floating electrode 120 from continuing to float downward, that is, the resisting structure 1123 can limit the freedom of the floating electrode 120 in the first preset direction F1. On the one hand, it can improve the fit between the floating electrode 120 and the part to be massaged and prevent the floating electrode 120 from floating downward without restriction. On the other hand, it can also prevent the floating electrode 120 from touching the air pump 111, that is, the resisting structure 1123 protects the air pump 111.

[0065] Furthermore, when the floating seat 121 or the electrode massage member 122 abuts against the resisting structure 1123, the floating seat 121 is in the maximum compression stroke, and the peripheral wall of the floating seat 121 is compressed in the preset direction F, but the peripheral wall of the floating seat 121 is not completely compressed. The so-called "not completely compressed" here means that if there is no resisting structure 1123, the floating seat 121 can continue to be compressed to the limit compression state in the preset direction F. By setting the resisting structure 1123, it is possible to avoid the floating seat 121 from being compressed to the limit compression state, thereby avoiding the connecting hole K4 from being closed due to the compression of the floating seat 121. In other words, by setting the resisting structure 1123, it can be ensured that when the floating seat 121 is in the maximum compression stroke, the connecting hole K4 is still not closed, and the outer chamber Q2 and the inner chamber Q1 can be connected through the connecting hole K4, so that the air pump 111 can continue to extract air to maintain the negative pressure state of the floating chamber Q.

[0066] Please combine Figure 6 Reference Figure 8 The peripheral wall of the floating seat 121 includes a plurality of connecting parts 1212, and the plurality of connecting parts 1212 are sequentially connected to form wrinkles. An angle is formed between two adjacent connecting parts 1212, and the connecting hole K4 is at least partially disposed at the connection between the two connecting parts 1212. When the resisting structure 1123 abuts against the floating seat 121 or the electrode massage member 122, the two connecting parts 1212 are not overlapped to form a gap, and the gap connects the outer chamber Q2 and the connecting hole K4.

[0067] Specifically, along the preset direction F, the floating seat 121 is designed as a cyclically undulating corrugated structure, which is the above-mentioned folds, and the floating seat 121 can be extended or shortened along the preset direction F through the folds, thereby achieving up and down floating. The folds are composed of connecting parts 1212, and the connecting parts 1212 are inclined relative to the preset direction F, and the inclined directions of two adjacent connecting parts 1212 are different, that is, the two adjacent connecting parts 1212 are bent and connected, and the connecting hole K4 is provided at the bent connection of the two connecting parts 1212. When the resisting structure 1123 abuts against the floating seat 121 or the electrode massage member 122, the two connecting parts 1212 do not overlap each other. Therefore, there is still a gap between the two connecting parts 1212, and the connecting hole K4 is not closed. The connecting hole K4 can be connected to the outer chamber Q2 through the gap, thereby ensuring that the outer chamber Q2 and the inner chamber Q1 are always in a connected state, so that the air pump 111 can continue to draw air to maintain the negative pressure state of the floating chamber Q.

[0068] Please refer to Figure 6 When the floating seat 121 floats downward, the size of the outer peripheral wall of the floating seat 121 expands toward the elastic surrounding edge 130. When the resisting structure 1123 abuts against the floating seat 121 or the electrode massage member 122, the outer peripheral wall of the floating seat 121 is spaced from the inner peripheral wall of the elastic surrounding edge 130 at the maximum expansion position.

[0069] Specifically, when the floating electrode 120 floats downward, the electrode massage member 122 and the pump mounting seat 112 (or the elastic surrounding edge 130) squeeze the floating seat 121 from both ends of the floating seat 121, and the squeezing action causes the outer peripheral wall of the floating seat 121 to expand outward, that is, the outer peripheral wall expands in the direction of the elastic surrounding edge 130. When the resisting structure 1123 abuts against the floating seat 121 or the electrode massage member 122, the resisting structure 1123 limits the floating of the floating seat 121. When the floating seat 121 cannot continue to float downward, the outer peripheral wall of the floating seat 121 cannot continue to expand outward. At this time, the outer peripheral wall is in the maximum expansion position, and the outer peripheral wall of the floating seat 121 is spaced apart from the inner peripheral wall of the elastic surrounding edge 130. It can be understood that if the outer peripheral wall of the floating seat 121 fits the inner peripheral wall of the elastic surrounding edge 130, the connecting hole K4 on the floating seat 121 will be covered by the inner peripheral wall of the elastic surrounding edge 130. In this embodiment, the outer peripheral wall of the floating seat 121 is set to be spaced apart from the inner peripheral wall of the elastic edge 130 when in the maximum expansion position, so that the outer peripheral wall of the floating seat 121 can always maintain a gap with the inner peripheral wall of the elastic edge 130 at any expansion position, thereby ensuring that the connecting hole K4 is not blocked or covered by the inner peripheral wall of the elastic edge 130, so that the outer chamber Q2 and the inner chamber Q1 can always be connected through the connecting hole K4, and the air pump 111 can continue to draw air to maintain the negative pressure state of the floating chamber Q.

[0070] Optionally, at least part of the air pump assembly 110 is located in the area surrounded by the elastic surrounding edge 130 in a preset direction F. When the elastic surrounding edge 130 is compressed to form a negative pressure, the center of gravity of the air pump assembly 110 is close to the negative pressure port K2 of the floating chamber Q. The preset direction F is the relative direction between the floating electrode 120 and the air pump assembly 110.

[0071] Specifically, the elastic peripheral edge 130 can be roughly regarded as an annular structure, which has a first end D1 and a second end D2 in the preset direction F, and the space area surrounded by the first end D1 and the second end D2 of the elastic peripheral edge 130 is the above-mentioned "area surrounded by the elastic peripheral edge 130". Further, the above-mentioned "at least part of the air pump assembly 110 is arranged in the area surrounded by the elastic peripheral edge 130 along the preset direction F" means "at least part of the air pump assembly 110 is located between the first end D1 and the second end D2 of the elastic peripheral edge 130".

[0072] When the negative pressure massage head 10 is adsorbed on the part to be massaged, the elastic rim 130 will be compressed in the preset direction F, that is, the size of the elastic rim 130 in the preset direction F will be reduced, so that the center of gravity of the air pump assembly 110 is closer to the negative pressure port K2, or in other words, the center of gravity of the air pump assembly 110 is closer to the part to be massaged, thereby reducing the lever arm length corresponding to the air pump assembly 110's own gravity (the distance from the center of gravity of the air pump assembly 110 to the part to be massaged), thereby reducing the gravity torque brought by the air pump assembly 110 (gravity torque = lever arm length × gravity), thereby reducing the possibility of the negative pressure massage head 10 falling off from the part to be massaged. In other words, this ensures that the negative pressure massage head 10 can be more stably adsorbed on the part to be massaged.

[0073] Please refer to further Fig. 9 It can be understood that the negative pressure massage head 10 itself has a certain weight, especially the air pump assembly 110. The distance from the center of gravity of the negative pressure massage head 10 to the part to be massaged is the arm length L. The product of the gravity G of the negative pressure massage head 10 and the arm length L is the gravity moment Mg of the negative pressure massage head 10. If the gravity moment Mg is too large, the negative pressure massage head 10 will flip and fall off from the part to be massaged. In this embodiment, at least part of the air pump assembly 110 is arranged in the area surrounded by the elastic surrounding edge 130 along the preset direction F, so that the center of gravity of the air pump assembly 110 can be closer to the part to be massaged, and thus the center of gravity of the entire negative pressure massage head 10 will also be closer to the part to be massaged. Although the gravity G of the negative pressure massage head 10 remains unchanged, the arm length L will be reduced, and the gravity moment Mg will be reduced accordingly, so that the possibility of the negative pressure massage head 10 flipping and detaching from the part to be massaged can be reduced.

[0074] Optionally, a dimension of the air pump assembly 110 in the preset direction F is less than or equal to 1 / 2 of a maximum compression stroke of the elastic surrounding edge 130 in the preset direction F.

[0075] Specifically, the "maximum compression stroke of the elastic surrounding edge 130 in the preset direction F" refers to the "maximum compression amount of the elastic surrounding edge 130 in the preset direction F". In this embodiment, the maximum size of the air pump assembly 110 in the preset direction F is limited to be less than or equal to 1 / 2 of the maximum compression stroke of the elastic surrounding edge 130 in the preset direction F, so that the thickness of the air pump assembly 110 in the preset direction F can be limited to not be too large, so as to avoid the excessive thickness causing its center of gravity to be away from the negative pressure port K2 along the preset direction F, thereby reducing the possibility of the negative pressure massage head 10 falling relative to the human body. In addition, the above-mentioned size limitation can also prevent the thickness of the air pump assembly 110 in the preset direction F from being too large and hindering the compression process of the elastic surrounding edge 130. It can be understood that if the compression stroke of the elastic surrounding edge 130 is too small, the air discharge amount of the floating cavity Q is small, the negative pressure effect is poor, and it is not conducive to adsorption. On the contrary, after the size of the air pump assembly 110 is limited, it can be ensured that the elastic surrounding edge 130 has a sufficient compression stroke, thereby achieving a more stable negative pressure adsorption effect.

[0076] Please refer to Figure 5 , Figure 6 , Fig.10 The elastic edge 130 has a first end D1 and a second end D2 opposite to each other. The first end D1 is connected to the air pump assembly 110, and the second end D2 is provided with a fitting portion M2 surrounding the negative pressure port K2. The fitting portion M2 is used to adhere to the massaged part to form an adsorption effect. The negative pressure massage head 10 has a first state (see Figure 6 ) and the second state (see Fig.10 ). When the negative pressure massage head 10 is in the first state, the second end D2 of the elastic rim 130 away from the air pump assembly 110 protrudes from the first side C1 of the air pump assembly 110, and the elastic rim 130 and the air pump assembly 110 together form the floating cavity Q. When the negative pressure massage head 10 is in the second state, the second end D2 of the elastic rim 130 is turned outward to the second side C2 of the air pump assembly 110, so that the floating electrode 120 is exposed to the first side C1 of the air pump assembly 110.

[0077] Specifically, since the first end D1 of the elastic edge 130 is connected to the air pump assembly 110 and fixed, the second end D2 is free, and the elastic edge 130 can be elastically deformed, the elastic edge 130 can be "turned outward" or "flipped" through the second end D2, so that the negative pressure massage head 10 can be in the first state and the second state.

[0078] From a static perspective, when the negative pressure massage head 10 is in the first state, the second end D2 of the elastic edge 130 is located on the first side C1 of the air pump assembly 110; when the negative pressure massage head 10 is in the second state, the second end D2 of the elastic edge 130 is located on the second side C2 of the air pump assembly 110.

[0079] From a dynamic perspective, when the negative pressure massage head 10 switches from the first state to the second state, the second end D2 of the elastic rim 130 "turns outward" from the first side C1 of the air pump assembly 110 to the second side C2 of the air pump assembly 110, the floating electrode 120 is exposed to the outside from the floating cavity Q, and the elastic rim 130 surrounds the outer periphery of the air pump assembly 110. When the negative pressure massage head 10 switches from the second state to the first state, the second end D2 of the elastic rim 130 "turns inward" from the second side C2 of the air pump assembly 110 to the first side C1 of the air pump assembly 110, and the elastic rim 130 surrounds the outer periphery of the floating electrode 120, that is, the floating electrode 120 returns to the floating cavity Q.

[0080] It should be noted that the above-mentioned "external rotation" and "inner rotation" are two opposite turning processes of the elastic surrounding edge 130, or "external rotation" and "inner rotation" refer to the process of exchanging the inside and outside of the elastic surrounding edge 130. Specifically, the elastic surrounding edge 130 has an outer wall surface M4 and an inner wall surface M3 that are arranged opposite to each other. When the negative pressure massage head 10 is in the first state, the outer wall surface M4 is exposed to the outside world, and the inner wall surface M3 is away from the outside world. At this time, the inner wall surface M3 faces the floating electrode 120 and surrounds the outer periphery of the floating electrode 120. When the negative pressure massage head 10 is in the second state, the inner wall surface M3 is exposed to the outside world, and the outer wall surface M4 is away from the outside world. At this time, the outer wall surface M4 faces the air pump assembly 110 and surrounds the outer periphery of the air pump assembly 110.

[0081] It can be understood that the elastic edge 130 can be flipped between the first side C1 and the second side C2 of the air pump assembly 110, which means that the elastic edge 130 has a larger size in the preset direction F. The elastic edge 130 can thus enclose a larger floating cavity Q. A larger floating cavity Q means a larger amount of air can be discharged, thereby making it easier for the floating cavity Q to form a negative pressure effect.

[0082] When the negative pressure massage head 10 needs to be adsorbed on the part to be massaged, the second end D2 of the elastic edge 130 can be first turned outward from the first side C1 of the air pump assembly 110 to the second side C2, so that the negative pressure massage head 10 is changed from the first state to the second state, and then the negative pressure massage head 10 is aligned with the part to be massaged. Finally, the elastic edge 130 is deformed by itself, or the user applies force to flip the second end D2 of the elastic edge 130 from the second side C2 of the air pump assembly 110 to the first side C1, so that the negative pressure massage head 10 is changed from the second state to the first state, and the fitting portion M2 of the elastic edge 130 is fitted on the massage part. At this time, the volume of air entering the floating cavity Q is less than the maximum volume of the floating cavity Q (that is, the volume of the floating cavity Q corresponding to the natural state of the negative pressure massage head 10). The negative pressure massage head 10 thus initially forms a negative pressure effect with the part to be massaged, and is adsorbed on the part to be massaged through the negative pressure port K2. In the above operation process, the negative pressure effect can be initially formed without the intervention of the air pump 111, so that the negative pressure massage head 10 can be quickly self-primed and positioned at the massaged part, and it is not easy to fall off. After the negative pressure massage head 10 is initially self-primed at the massaged part, the air pump 111 is used to extract the air in the floating cavity Q, which can further reduce the air pressure in the floating cavity Q, so that the negative pressure massage head 10 is more stably adsorbed on the massaged part.

[0083] It should be noted that the first state includes a first sub-state of adsorption and a second sub-state of non-adsorption, wherein the first sub-state of adsorption refers to the state in which the negative pressure massage head 10 is adsorbed on the part to be massaged, and the second sub-state of non-adsorption refers to the state in which the negative pressure massage head 10 is not adsorbed on the part to be massaged and is not subjected to any external force (also referred to as a natural state). Furthermore, when the negative pressure massage head 10 is in the first sub-state, the first dimension of the elastic surrounding edge 130 in the preset direction F is smaller than the second dimension of the elastic surrounding edge 130 in the preset direction F when the negative pressure massage head 10 is in the second sub-state. Only when this condition is met can at least part of the air in the floating cavity Q be discharged to the outside, that is, the elastic surrounding edge 130 needs to be compressed in the preset direction F to form a negative pressure effect.

[0084] Furthermore, during the process of the negative pressure massage head 10 switching from the first state to the second state, the range through which the fitting portion M2 moves from the first side C1 to the second side C2 is a preset range, and the air pump assembly 110 is located within the preset range. In this way, the air pump assembly 110 is appropriately positioned in the preset direction F of the negative pressure massage head 10, and is not too far from the negative pressure port K2, thereby preventing the air pump assembly 110 from being too far away from the negative pressure port K2 and causing the negative pressure massage head 10 to fall off the part to be massaged, and also allowing the elastic surrounding edge 130 to have a larger deformation range, which is conducive to the elastic surrounding edge 130 being able to deform and adapt to different parts to be massaged.

[0085] Please refer to Figure 6 The pump mounting seat 112 includes a bottom shell 1121 away from the fitting portion M2, and the bottom shell 1121 is provided with a harness fixing hole K3, and the harness fixing hole K3 is used for the harness 30 to pass through, so that the harness 30 is electrically connected to the air pump 111, and the angle α formed by the central axis Y of the harness fixing hole K3 and the fitting portion M2 is greater than or equal to 0° and less than or equal to 60°, so that the harness 30 is parallel to or close to the side where the fitting portion M2 is located under the constraint of the harness fixing hole K3. The angle α can be, but is not limited to, 0°, 5°, 10°, 15°, 20°, 23°, 25°, 30°, 35°, 38°, 40°, 45°, 50°, 55°, 57°, and 60°.

[0086] Specifically, when the user is using the massage device, it is inevitable that the user will touch the wire harness 30, and the wire harness 30 will pull the negative pressure massage head 10. If the pulling force of the wire harness 30 on the negative pressure massage head 10 is in the direction from the first side C1 to the second side C2 (herein referred to as the falling direction), or the component of the pulling force in the falling direction is greater than zero, then the negative pressure massage head 10 has a tendency to separate from the massaged part. When the force applied to the negative pressure massage head 10 in the falling direction exceeds the negative pressure adsorption force, the negative pressure massage head 10 will fall off from the massaged part.

[0087] Based on this, in this embodiment, the angle α formed by the central axis Y of the harness fixing hole K3 and the fitting portion M2 is set to be greater than or equal to 0° and less than or equal to 60°. It can be understood that the extension direction of the central axis Y of the harness fixing hole K3 is the extension direction of the harness 30, and further, the direction of the pulling effect of the harness 30 on the negative pressure massage head 10 is also the extension direction of the central axis Y of the harness fixing hole K3. When the angle α is equal to 0° (such as Figure 6 As shown), it means that the central axis Y of the harness fixing hole K3 is parallel to the fitting portion M2 (as shown Figure 6 As shown), at this time, the pulling force of the harness 30 in the direction of shedding is zero. Fig.11 As shown in FIG. 1 , the pulling force of the harness 30 in the direction of shedding is a negative force, that is, the negative pressure massage head 10 will be pulled by the harness 30 in the opposite direction of the shedding direction (that is, the direction from the second side C2 to the first side C1). It can be seen that when the angle α is limited to a range greater than or equal to 0° and less than or equal to 60°, the negative pressure massage head 10 can be effectively prevented from being separated from the massaged part due to the pulling effect of the harness 30.

[0088] by Fig.11For example, the angle α formed by the central axis Y of the harness fixing hole K3 and the fitting portion M2 is 17°, and the pulling force FL of the harness 30 on the negative pressure massage head 10 can be decomposed into a first force component FL1 and a second force component FL2, wherein the direction of the first force component FL1 is the direction from the second side C2 to the first side C1, so the first force component FL1 can cause the negative pressure massage head 10 to further press the part to be massaged. The direction of the second force component FL2 is perpendicular to the direction from the second side C2 to the first side C1, so the second force component FL2 has a tendency to cause the negative pressure massage head 10 to slide along the surface of the part to be massaged, but will not cause the negative pressure massage head 10 to detach from the part to be massaged.

[0089] In summary, the negative pressure massage head 10 provided by the present application includes an elastic rim 130, an air pump assembly 110, and a floating electrode 120, wherein the elastic rim 130 and the air pump assembly 110 are jointly enclosed to form a floating cavity Q of a first spatial volume, and the floating electrode 120 is disposed in the floating cavity Q, thereby dividing the floating cavity Q into two chambers, one of which is an inner cavity Q1 jointly enclosed by the floating electrode 120 and the air pump assembly 110, and the other is an outer cavity Q2 jointly enclosed by the floating electrode 120 and the elastic rim 130. A connecting hole K4 is provided on the floating electrode 120, and the connecting hole K4 connects the inner cavity Q1 and the outer cavity Q2 together, and a height difference H5 is formed between the connecting hole K4 and the bottom wall M8 of the outer cavity Q2. The air pump 111 is arranged in the inner chamber Q1. When the air pump 111 is working and sucking air, the air pressure in the inner chamber Q1 is reduced, and the air pressure in the outer chamber Q2 connected to the inner chamber Q1 through the connecting hole K4 can also be reduced accordingly, so as to ensure that the negative pressure massage head 10 is stably adsorbed on the part to be massaged. It can be understood that since the air pump 111 is arranged in the inner chamber Q1, it can not only reduce the air pump 111 to occupy other spaces, but also protect the air pump 111. In addition, when the floating electrode 120 is squeezed by the part to be massaged and the air is compressed, it is also conducive to the pump to quickly suck air to form negative pressure. At the same time, a height difference H5 is formed between the connecting hole K4 and the floating chamber Q, so that when performing negative pressure adsorption massage, the sweat and other liquids sucked into the outer chamber Q2 flow into the bottom of the outer chamber Q2, and will not easily enter the inner chamber Q1 from the connecting hole K4, thereby reducing the possibility of the sweat and other liquids entering and causing damage to the air pump 111.

[0090] Please refer to Figure 6The floating electrode has an electrode surface M5, and the electrode surface M5 is used to massage the massaged part, and the electrode surface M5 is located in the floating cavity Q. The elastic surrounding edge 130 has a first end D1 and a second end D2 that are opposite to each other. The first end D1 is connected to the pump mounting seat 112, and the second end D2 has a fitting portion M2. The fitting portion M2 is suitable for fitting with the massaged part to form a closure for the floating cavity Q. The elastic surrounding edge 130 has the ability to deform along the axial direction of the negative pressure port K2 and the circumferential direction of the negative pressure port K2 to adapt to the rotation of the massaged part.

[0091] In this embodiment, the first end D1 of the elastic surrounding edge 130 is connected to the pump mounting seat 112, and together with the pump mounting seat 112, a floating cavity Q is formed, and a floating electrode 120 for massaging the part to be massaged is disposed in the floating cavity Q. The second end D2 of the elastic surrounding edge 130 has a fitting portion M2, and the fitting portion M2 is formed to form a negative pressure port K2 connected to the floating cavity Q. When the negative pressure massage head 10 massages the area to be massaged (such as the neck) through the electrode surface M5 of the floating electrode 120, the fitting portion M2 of the elastic rim 130 can be adsorbed on the area to be massaged through the negative pressure port K2. Since the fitting portion M2 is in close contact with the area to be massaged, the floating cavity Q forms a closed space. It can be understood that at this time, the electrode surface M5 located in the floating cavity Q will not be touched by foreign objects (such as the collar on the neck). In other words, the elastic rim 130 isolates foreign objects from the electrode surface M5 and plays a role of isolation and protection, thereby preventing foreign objects from contacting the electrode surface M5 and causing poor contact, thereby causing a tingling sensation in the area to be massaged. In addition, since the elastic surrounding edge 130 has the ability to deform along the axial and circumferential directions of the negative pressure port K2, when the negative pressure massage head 10 is adsorbed on the part to be massaged, the rotation or twisting of the part to be massaged will generate a pulling force on the elastic surrounding edge 130 in the front-to-back direction and the left-to-right direction, so that the elastic surrounding edge 130 can be adaptively deformed, and the fitting portion M2 of the elastic surrounding edge 130 can still fit with the part to be massaged, and can better fit with the part to be massaged to form a closed space, so as to stably adsorb on the part to be massaged. Therefore, the negative pressure massage head 10 provided by the present application can better prevent the part to be massaged from tingling and ensure that it is stably adsorbed on the part to be massaged during the massage process.

[0092] 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.
