Abstract
Description
Technical Field
[0001] The present application relates to the technical field of massage instruments, and in particular to a massage head and a massage instrument. Background Art
[0002] In recent years, with the improvement of people's living standards, various massage devices have become more and more popular. Massagers can massage the shoulders and necks and other parts to relieve the discomfort such as muscle soreness caused by users in long-term study or work. Among them, negative pressure massagers are widely used, but in related negative pressure massagers, the skin is continuously sucked into the negative pressure chamber during the negative pressure adsorption process, and the bulge formed by the skin in the negative pressure chamber has different degrees of bulging. As the degree of bulging changes, the fit between the electric stimulation massage piece and the skin will continue to change, which makes it difficult for the electric stimulation massage piece to fit stably. This situation is likely to cause a tingling sensation to the skin, thereby affecting the massage effect. Utility Model Content
[0003] In a first aspect, an embodiment of the present application provides a massage head, the massage head comprising:
[0004] A shell, wherein the shell is provided with a first opening and a first cavity in communication, the first opening is arranged to face the area to be massaged so that the area to be massaged passes through the first opening and enters the first cavity, and the first cavity is arranged to be in communication with a negative pressure device; and
[0005] A floating head, wherein the floating head is provided with a second cavity; the floating head is connected to the housing and is located in the first cavity; an electric stimulation massage sheet is provided on a side of the floating head facing the first opening; the electric stimulation massage sheet is configured to be electrically connected to a circuit board; the first cavity and the second cavity are isolated;
[0006] When the first cavity forms a negative pressure that is less than the air pressure in the second cavity, the floating head expands and drives the electric stimulation massage sheet to move toward the first opening.
[0007] In a second aspect, an embodiment of the present application provides a massager, comprising an electrically connected massage head and a circuit board, wherein the massage head is the massage head of the first aspect.
[0008] In the massage head provided in the embodiment of the present application, by providing a first chamber connected to a negative pressure device and a floating head with an expansion function, the floating head can drive the electric stimulation massage sheet to move when it expands, so as to achieve a massage effect.
[0009] When using the massager, place the massage head at the area to be massaged, and the area to be massaged blocks the first opening. The negative pressure device performs negative pressure evacuation on the first cavity to form a negative pressure in the first cavity, and at the same time makes the air pressure in the first cavity less than the air pressure in the second cavity, so that the second cavity expands. When in use, the pressure difference between the first cavity and the second cavity can be used to expand the floating head, that is, while the skin is adsorbed into the first cavity under the action of negative pressure, the electric stimulation massage sheet also moves toward the skin to fit the skin, which is conducive to ensuring stable contact between the electric stimulation massage sheet and the skin and ensuring the reliability of the massage.

[0028] Please also read Figure 1 and Figure 2 , Figure 1 A three-dimensional schematic diagram of a massager provided in one embodiment of the present application from one viewing angle; Figure 2 A cross-sectional view of a massage head provided in one embodiment of the present application from one perspective. The massager 100 includes a massage head 10 and a circuit board 20, the circuit board 20 is electrically connected to the massage head 10, and the massage head 10 is used to massage the human body. For example, the massage head 10 can massage the shoulders, neck, waist, legs, etc. of the human body. The massager 100 can be, but is not limited to, a shoulder and neck massager 100, a waist massager 100, or a leg massager 100, etc.
[0029] In this embodiment, the circuit board 20 is disposed on the massage head 10, and the circuit board 20 is connected to the massage head 10 via a wire 30. It can be understood that in other embodiments, the circuit board 20 can also be disposed separately from the massage head 10.
[0030] Please continue reading Figure 1 and Figure 2 The massager 100 further includes a negative pressure device 40, which is connected to the massage head 10 through an air pipe 41 and is used to evacuate air from the massage head 10 so that the massage head 10 can absorb the human skin through negative pressure absorption, so that the massage head 10 can massage the human body.
[0031] Furthermore, the negative pressure device 40 is an air pump. In other embodiments, the negative pressure device 40 may also be other power devices with a negative pressure air extraction function.
[0032] The specific structure of the massage head 10 is described in detail below. The massage head 10 includes a housing 11 and a floating head 12. The housing 11 is provided with a first opening 111 and a first cavity 112 that are connected. The first opening 111 is configured to face the massaged area 200 so that the massaged area 200 passes through the first opening 111 and enters the first cavity 112. The first cavity 112 is configured to be connected to a negative pressure device 40. An electric stimulation massage sheet 121 is provided on one side of the floating head 12 facing the first opening 111. The electric stimulation massage sheet 121 is configured to be electrically connected to the circuit board 20.
[0033] The floating head 12 is provided with a second cavity 122, and the second cavity 122 is isolated from the first cavity 112. The floating head 12 is connected to the housing 11 and is located in the first cavity 112. When the first cavity 112 forms a negative pressure less than the air pressure in the second cavity 122, the floating head 12 expands and drives the electric stimulation massage sheet 121 to move toward the first opening 111.
[0034] When using the massager 100, the massage head 10 is placed on the area to be massaged 200, and the area to be massaged 200 blocks the first opening 111. The negative pressure device 40 performs negative pressure evacuation on the first cavity 112 to form a negative pressure in the first cavity 112, and at the same time, the air pressure in the first cavity 112 is less than the air pressure in the second cavity 122, so that the second cavity 122 expands. When in use, the massager 100 can use the pressure difference between the first cavity 112 and the second cavity 122 to expand the floating head 12, that is, while the skin of the area to be massaged 200 is adsorbed into the first cavity 112 under the action of negative pressure, the electric stimulation massage sheet 121 also moves toward the skin to fit the skin, which is conducive to ensuring stable contact between the electric stimulation massage sheet 121 and the skin, and ensuring the reliability of the massage.
[0035] It can be understood that the shape of the first opening 111 can be, but is not limited to, a circle.
[0036] In this embodiment, one end of the wire 30 is connected to the circuit board 20 , and the other end extends into the second cavity 122 and is electrically connected to the electric stimulation massage sheet 121 , so that the electric stimulation massage sheet 121 can generate electrical stimulation to the massage area 200 .
[0037] In one embodiment, when the floating head 12 is in a natural state, the electric stimulation massage sheet 121 is located on the side of the end face where the first opening 111 is located facing the second cavity 122, and the distance between the electric stimulation massage sheet 121 and the end face where the first opening 111 is located is 2mm-5mm. The natural state of the floating head 12 refers to the state where the floating head 12 is not expanded. The distance between the electric stimulation massage sheet 121 and the end face where the first opening 111 is located is defined as the first distance h1. The first distance h1 can be, but is not limited to, 2mm, or 2.5mm, or 3mm, or 3.5mm, or 4mm, or 4.5mm, or 5mm, or other values other than the above examples and satisfying the range of the first distance h1. When the floating head 12 expands, the electric stimulation massage sheet 121 can move the first distance h1 and then contact the area to be massaged 200 to achieve a massage effect. The first distance h1 is set within the range of 2mm-5mm. On the one hand, it makes it difficult for the electric stimulation massage sheet 121 to fail to contact the area to be massaged 200 due to the large distance from the area to be massaged 200; on the other hand, a certain moving space is provided for the electric stimulation massage sheet 121, which is conducive to the expansion and deformation of the floating head 12.
[0038] In one embodiment, the maximum inner diameter of the first cavity 112 is 30 mm to 100 mm, and the maximum inner diameter of the second cavity 122 when the floating head 12 is in a natural state is 40% to 70% of the inner diameter of the first cavity 112. The maximum inner diameter of the first cavity 112 is defined as the first inner diameter L1, that is, the range of the first inner diameter L1 is 30 mm to 100 mm; the maximum inner diameter of the second cavity 122 when the floating head 12 is in a natural state is defined as the second inner diameter L2, that is, the range of the second inner diameter L2 is 40% to 70% of the first inner diameter L1. The first inner diameter L1 can be, but is not limited to, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, 65 mm, 70 mm, 75 mm, 80 mm, 85 mm, 90 mm, 95 mm, or 100 mm, or other values other than the above examples and satisfying the range of the first inner diameter L1.
[0039] For example, when the first inner diameter L1 is 30 mm, the second inner diameter L2 is in the range of 12 mm-21 mm, that is, the second inner diameter L2 may be, but is not limited to, 12 mm, or 14 mm, or 16 mm, or 18 mm, or 20 mm, or 21 mm, or other values other than the above examples and satisfying the range of 12 mm-21 mm;
[0040] When the first inner diameter L1 is 100 mm, the range of the second inner diameter L2 is 40 mm-70 mm, that is, the second inner diameter L2 can be but is not limited to 40 mm, or 45 mm, or 50 mm, or 55 mm, or 60 mm, or 65 mm, or 70 mm, or other values in addition to the above examples and satisfying the range of 40 mm-70 mm.
[0041] The first inner diameter L1 is limited to the range of 30mm-100mm. On the one hand, it can avoid or reduce the problem that the massage head 10 cannot absorb the massaged area 200 due to the small area when the massaged area 200 is under negative pressure. On the other hand, due to the uneven flatness of the massaged area 200, such a setting can avoid or reduce the problem of air leakage due to the large absorption area. The first inner diameter L1 and the second inner diameter L2 meet the above set values, which is conducive to the formation of a negative pressure environment in the first cavity 112 and the formation of a state in which the air pressure of the second cavity 122 is greater than the negative pressure of the first cavity 112.
[0042] In one embodiment, the housing 11 is further provided with a second opening 113, the floating head 12 is connected to the second opening 113, and the second cavity 122 is configured to be connected to the external environment. After the second cavity 122 is connected to the external environment, it is convenient for the air pressure of the second cavity 122 to be maintained at the same state as the atmospheric pressure, so that when the air in the first cavity 112 is extracted, it is easy for the first cavity 112 to form a pressure difference with the second cavity 122, so that the air pressure of the second cavity 122 is greater than the negative pressure of the first cavity 112, so that the floating head 12 expands under the force of the atmospheric pressure and extends from the first opening 111, so that the floating head 12 contacts the massaged area 200 to achieve a massage effect.
[0043] Furthermore, the outer wall of the floating head 12 is connected to the inner wall of the second opening 113, so that the floating head 12 blocks the second opening 113, and the floating head 12 can be loaded into the first cavity 112 from the second opening 113. The side of the floating head 12 facing away from the electric stimulation massage sheet 121 has an inlet 123, and the second cavity 122 is connected to the external environment through the inlet 123.
[0044] It is understandable that in other embodiments, the floating head 12 may also be connected to the inner wall of the first cavity 112 near the second opening 113 , so that the second cavity 122 is in communication with the external environment through the second opening 113 .
[0045] In another embodiment, the housing 11 is also provided with a second opening 113 , the floating head 12 is connected to the second opening 113 , and the second cavity 122 is configured to be connected to an air pump so that the air pump inflates the second cavity 122 to increase the air pressure of the second cavity 122 .
[0046] Furthermore, the air pump is directly connected to the second cavity 122. In other embodiments, when the second cavity 122 is connected to the external environment through the second opening 113, the air pump can also input gas into the second cavity 122 through the second opening 113.
[0047] After the air pump inflates the second cavity 122, the air pressure in the second cavity 122 can be further increased. By controlling the inflation rate of the air pump to control the air pressure in the second cavity 122, it is convenient to adjust the pressure difference between the first cavity 112 and the second cavity 122, and adjust the strength of the massage head 10 against the massage area 200. By using the air pump to inflate the second cavity 122 and the negative pressure device 40 to evacuate the first cavity 112, the massage strength of the massage head 10 can be selectively adjusted according to massage needs, thereby improving the massage experience of the user.
[0048] In one embodiment, the housing 11 is provided with a third opening 114, which is located on a side of the first cavity 112 away from the first opening 111 and is configured to be connected to the negative pressure device 40. For example, the third opening 114 is connected to the air outlet of the negative pressure device 40 through the air pipe 41.
[0049] In this embodiment, the third opening 114 is arranged at a position away from the electric stimulation massage sheet 121 of the floating head 12, which is beneficial to reduce the interference between the third opening 114 and the moving electric stimulation massage sheet 121, so as to reduce the situation where the electric stimulation massage sheet 121 blocks part or all of the third opening 114, thereby affecting the effect of forming negative pressure in the first cavity 112.
[0050] It can be understood that in other embodiments, the third opening 114 can also be disposed at other positions of the housing.
[0051] In one embodiment, the housing 11 is provided with a conductive surface 115, which is arranged around the first opening 111, and the conductive surface 115 is configured to be electrically connected to the circuit board 20. During massage, the conductive surface 115 contacts the area to be massaged 200, so that the conductive surface 115, the electric stimulation massage sheet 121, the circuit board 20 and the area to be massaged 200 form a current loop, so that the conductive surface 115 can cooperate with the electric stimulation massage sheet 121 to form electrical stimulation to the area to be massaged 200. Compared with the electric stimulation massage sheet 121 electrically stimulating the area to be massaged 200 alone, the conductive surface 115 and the electric stimulation massage sheet 121 simultaneously electrically stimulate the area to be massaged 200, which increases the massage area of the massager 100 on the skin, which is conducive to improving user experience.
[0052] Specifically, the wire 30 connecting the massage head 10 and the circuit board 20 includes a first wire 31 and a second wire 32 . The electric stimulation massage sheet 121 is electrically connected to the circuit board 20 via the first wire 31 , and the conductive surface 115 is electrically connected to the circuit board 20 via the second wire 32 .
[0053] The structure of the floating head 12 is described in detail below. The floating head 12 includes a telescopic sleeve 124 and a contact piece 125. The telescopic sleeve 124 is connected to the housing 11, and the contact piece 125 is a hard structure. The contact piece 125 is arranged at one end of the telescopic sleeve 124 facing the first opening 111, and the contact piece 125 and the telescopic sleeve 124 are surrounded to form a second cavity 122. The electric stimulation massage piece 121 is arranged on the side of the contact piece 125 facing the first opening 111.
[0054] The telescopic sleeve 124 is made of a soft material, which is conducive to the deformation of the telescopic sleeve 124. When the telescopic sleeve 124 is deformed, it can drive the contact piece 125 to move in the direction of contacting the massaged area 200. The contact piece 125 is made of a hard material, which is conducive to ensuring the fit between the electric stimulation massage piece 121 and the massaged area 200, reducing the user's piercing sensation.
[0055] Furthermore, the telescopic sleeve 124 and the contact piece 125 are both made of plastic material, and the telescopic sleeve 124 and the contact piece 125 are integrally formed, so as to facilitate the production of the floating head 12, and when the telescopic sleeve 124 expands, it is not easy to separate from the contact piece 125. In other embodiments, the telescopic sleeve 124 can also be made of plastic material alone, and the contact piece 125 can be made of plastic material alone, and the telescopic sleeve 124 and the contact piece 125 are connected as a whole by bonding.
[0056] Please also read Figure 3 , Figure 4 and Figure 5 , Figure 3 A three-dimensional schematic diagram of a massager provided in another embodiment of the present application from one viewing angle; Figure 4 This is a cross-sectional view of a massage head provided in another embodiment of the present application from one perspective. Figure 5 for Figure 4 In another embodiment, the contact sheet 125 further includes a heat-conducting film 1251, which is disposed on a side of the contact sheet 125 away from the first opening 111. The heat-conducting film 1251 is electrically connected to the circuit board 20. When the massage head 10 massages the massage area 200, the heat-conducting film 1251 is energized to generate heat, and the heat is transferred to the contact sheet 125 through heat conduction. The contact sheet 125 transfers the heat to the massage area 200, thereby improving the massage comfort.
[0057] Specifically, the wire 30 connecting the massage head 10 and the circuit board 20 includes a third wire 33 , and the thermal conductive film 1251 is connected to the circuit board 20 via the third wire 33 .
[0058] In another embodiment, the massage head 10 further includes a beating member 13, which is telescopically disposed in the second cavity 122 and is configured to move along the direction of the electric stimulation massage sheet 121 toward the first opening 111 to a side of the electric stimulation massage sheet 121 that protrudes toward the first opening 111. When the electric stimulation massage sheet 121 performs electrotherapy, the beating member 13 performs a beating function by telescopic movement in the second cavity 122, and the electrotherapy and beating are concentrated on the area to be massaged 200, thereby improving the massage effect.
[0059] The structure of the beating member 13 is described in detail below. The beating member 13 comprises a driving coil 131 and a beating portion 132, wherein the driving coil 131 is arranged around the second cavity 122 of the floating head 12 and is electrically connected to the circuit board 20. The beating portion 132 is arranged on the inner side surrounded by the driving coil 131 and is configured to form electromagnetic induction with the driving coil 131 so as to be retracted under the action of the driving coil 131. The contact sheet 125 is provided with a through hole 1252, and one end of the beating portion 132 can pass through the through hole 1252 and protrude to a side of the electric stimulation massage sheet 121 toward the first opening 111.
[0060] The driving coil 131 and the beating part 132 are located in the second cavity 122. On the one hand, the driving coil 131 can realize the telescopic movement of the beating part 132 after being energized, so that one end of the beating part 132 can pass through the through hole 1252 of the contact piece 125 and contact the massage area 200 to realize the beating function; on the other hand, the movement of the beating part 132 can be realized without an external mobile driving structure, so as to simplify the structure of the massage head 10.
[0061] Furthermore, the wire 30 connecting the massage head 10 and the circuit board 20 further includes a fourth wire 34 , and the driving coil 131 is electrically connected to the circuit board 20 via the fourth wire 34 .
[0062] In one embodiment, the distance that the beating portion 132 protrudes outside the electric stimulation massage sheet 121 is 2mm-5mm, and the distance that the beating portion 132 protrudes outside the electric stimulation massage sheet 121 is defined as the second distance h2, and the second distance h2 can be but is not limited to 2mm, or 2.5mm, or 3mm, or 3.5mm, or 4mm, or 4.5mm, or 5mm, or other numerical values other than the above examples and satisfying the scope of the second distance h2. The distance that the beating portion 132 protrudes outside the electric stimulation massage sheet 121 is greater than or equal to 2mm, and less than or equal to 5mm, which can avoid or reduce the situation that the beating effect is not obvious due to the second distance h2 being too small, and can also reduce the pulling limit displacement of the floating head 12, so as to reduce or avoid the possibility of the floating head 12 being damaged.
[0063] In one embodiment, the beating frequency of the beating portion 132 is 0.3HZ-10HZ. For example, the beating frequency of the beating portion 132 can be but is not limited to 0.3HZ, or 1.0HZ, or 1.5HZ, or 2.0HZ, or 2.5HZ, or 3.0HZ, or 3.5HZ, or 4.0HZ, or 4.5HZ, or 5.0HZ, or 5.5HZ, or 6.0HZ, or 6.5HZ, or 7.0HZ, or 7.5HZ, or 8.0HZ, or 8.5HZ, or 9.0HZ, or 9.5HZ, or 10.0HZ, or other values in addition to the above examples and satisfying the range of the beating frequency. The beating frequency is within this range, so that it is not easy to form a vibrating touch due to the beating frequency of the beating part 132 being too high, thereby reducing the beating effect, and it is not easy to reduce the massage effect generated by the beating due to the beating frequency of the beating part 132 being too low.
[0064] Furthermore, the beating member 13 further includes a beating piece 133, which is a soft structure. The beating piece 133 is connected to the contact piece 125 and blocks the through hole 1252. When the beating part 132 moves toward the first opening 111, the beating piece 133 can be driven to extend to contact the massaged area 200. After the beating piece 133 blocks the through hole 1252, the possibility of gas in the second cavity 122 leaking from the through hole 1252 to the first cavity 112 is reduced, which is more conducive to the negative pressure effect of the first cavity 112, and the sweat of the massaged area 200 is avoided or reduced from passing through the through hole 1252 into the second cavity 122 and contacting the beating part 132, resulting in corrosion or damage to the beating part 132.
[0065] In this embodiment, the hammer piece 133 is made of rubber. In other embodiments, the hammer piece 133 can also be a soft structure that can produce deformation, such as a plastic sheet.
[0066] Please also read Figure 6 and Figure 7 , Figure 6 This is a cross-sectional view of a massage head provided by another embodiment of the present application when the hammer piece is in contact with the area to be massaged. Figure 7 A cross-sectional view of a massage head provided by another embodiment of the present application in a state where the beat piece is away from the massaged area. Further, the beat piece 133 is connected to one end of the beating portion 132. When the beating portion 132 is rapidly extended and retracted, the beat piece 133 can be driven to repeatedly move in a direction close to and away from the massaged area 200, thereby reducing or avoiding the beat piece 133 from adhering to the massaged area 200 due to inertia and affecting the beating effect.
[0067] Further, the beat piece 133 includes a first portion 1331 and a second portion 1332, wherein the first portion 1331 is connected to the beating portion 132. The second portion 1332 surrounds the outer peripheral side of the first portion 1331, and the second portion 1332 is connected between the first portion 1331 and the contact piece 125. The first portion 1331 is located in the middle of the beat piece 133, which is easy to increase the deformation amount of the beat piece 133 when the beating portion 132 is beaten and extended, which is conducive to ensuring the massage strength and forming an effect similar to acupressure massage.
[0068] In this embodiment, the hammer piece 133 is circular, and the through hole 1252 on the contact piece 125 is also circular, so that the hammer piece 133 is easy to deform evenly and the hammer piece 133 is not easily damaged after repeated deformation.
[0069] It can be understood that the hammer piece 133 can be integrally formed with the contact piece 125, or can be separately provided and connected to the contact piece 125.
[0070] In one embodiment, the through hole 1252 of the contact sheet 125 corresponds to the middle part of the electric stimulation massage sheet 121. The axis of the through hole 1252 passes through the center of the electric stimulation massage sheet 121, so that the beating center point of the beating portion 132 is almost coincident with the center of the electric stimulation massage sheet 121, so that the beating element 13 beats the middle area of the electric stimulation massage sheet 121, and the uniformity of the electric stimulation around the beating portion 132 is improved, thereby improving the beating and electric stimulation effects.
[0071] Furthermore, the shape of the through hole 1252 can be set according to the shape of the hammer piece 133. For example, when the hammer piece 133 is circular, the through hole 1252 is also set to be circular so that the hammer piece 133 can protrude from the through hole 1252 to the side of the housing 11 facing the first opening 111.
[0072] In one embodiment, the massage head 10 further includes a guide sleeve 14, which is disposed on the contact piece 125 and is located in the second cavity 122. The guide sleeve 14 is connected to the through hole 1252, the drive coil 131 is wound around the outside of the guide sleeve 14, and the beating part 132 is slidably disposed in the guide sleeve 14. The guide sleeve 14 can limit the movement direction of the beating part 132, guide the beating part 132 to perform a beating action, and improve the movement stability of the beating part 132.
[0073] Further, the guide sleeve 14 has a sliding cavity 141, and the hammering part 132 is slidably disposed in the sliding cavity 141. An end of the guide sleeve 14 away from the contact piece 125 is provided with an opening 142 communicating with the sliding cavity 141, and the hammering part 132 can be installed into the sliding cavity 141 from the opening 142.
[0074] The guide sleeve 14 is made of the same material as the hammer piece 133 and is integrally formed. The guide sleeve 14 presses the edge of the hammer piece 133 against the through hole 1252 of the contact piece 125, so that the hammer piece 133 is not easily separated from the through hole 1252 of the contact piece 125 when deformed, thereby affecting the negative pressure effect of the first chamber 112.
[0075] In the embodiment where the maximum inner diameter of the first cavity 112 is 30mm-100mm, and the maximum inner diameter of the second cavity 122 when the floating head 12 is in the natural state is 40%-70% of the inner diameter of the first cavity 112, the outer diameter of the guide sleeve 14 is 8mm-20mm. The outer diameter of the guide sleeve 14 is defined as the first outer diameter L3, and the first outer diameter L3 can be but not limited to 8mm, or 10mm, or 12mm, or 14mm, or 16mm, or 18mm, or 20mm, or other values other than the above examples and satisfying the range of the first outer diameter L3. The maximum outer diameter of the second cavity 122 and the first outer diameter L3 meet the set value, which is conducive to making the relationship between the volume of the space between the outer side of the guide sleeve 14 and the inner wall of the second cavity 122 and the volume of the first cavity 112 conducive to forming the air pressure of the second cavity 122 greater than the negative pressure of the first cavity 112.
[0076] In one embodiment, the beating portion 132 is configured to protrude from the outside of at least one of the guide sleeve 14, the floating head 12 and the housing 11 when it moves in a direction away from the first opening 111. When the beating portion 132 moves in a direction away from the first opening 111, it can protrude to the outside of the housing 11 away from the first opening 111, thereby utilizing the external space of the massage head 10, reducing the setting length of the guide sleeve 14 along the moving direction of the beating portion 132, and further reducing the overall thickness of the housing 11, the guide sleeve 14 and the floating head 12 along the moving direction of the beating portion 132. The thickness of the housing 11 along the moving direction of the beating portion 132 is defined as the third distance h3. This embodiment can reduce the third distance h3, thereby facilitating the reduction of the overall volume of the massage head 10.
[0077] In this embodiment, the end face where the opening 142 of the guide sleeve 14 is located, the end face where the second opening 113 of the shell 11 is located, and the end face of the floating head 12 at the second opening 113 are flush, so that the beating portion 132 can protrude to the outside of the guide sleeve 14, the floating head 12 and the shell 11, thereby reducing the dimensions of the guide sleeve 14, the floating head 12 and the shell 11 in the moving direction of the beating portion 132 and reducing the overall volume of the massage head 10.
[0078] It is understandable that in other embodiments, the hammering portion 132 may also protrude independently from the outside of one of the guide sleeve 14 , the floating head 12 and the housing 11 .
[0079] See also Figure 8 , Figure 8A cross-sectional view of a massage head provided in another embodiment of the present application from one perspective. In another embodiment, the massager 100 includes two massage heads 10, and the two massage heads 10 can massage the area to be massaged 200 at the same time. When the two massage heads 10 are in contact with the area to be massaged 200 at the same time, a current loop is formed between the circuit board 20 of one massage head 10 and the electric stimulation massage sheet 121, the area to be massaged 200, and the electric stimulation massage sheet 121 of the other massage head 10 and the circuit board 20, so that the two massage heads 10 can electrically stimulate the area to be massaged at the same time.
[0080] The massager 100 in the present application, through the negative pressure pumping effect of the negative pressure device 40, can make the air pressure of the first chamber 112 reach a state less than the air pressure of the second chamber 122, under the influence of the pressure difference between the first chamber 112 and the second chamber 122, the floating head 12 is expanded, thereby driving the electric stimulation massage sheet 121 to move repeatedly toward or away from the place to be massaged 200, so as to achieve the effect of massage through the electric stimulation of the electric stimulation massage sheet 121; that is, when the skin can be adsorbed in the first chamber 112 under the effect of negative pressure, the electric stimulation massage sheet 121 also moves toward the skin to fit with the skin, which is conducive to ensuring the stable contact between the electric stimulation massage sheet 121 and the skin, and ensuring the reliability of massage. In addition, the beating part 132 performs telescopic movement under the electromagnetic induction of the driving coil 131, thereby achieving the effect of beating the place to be massaged 200. The massager 100 of the present application can superimpose the electric stimulation massage effect of the electric stimulation massage sheet 121 with the beating effect of the beating part 13, thereby further improving the massage effect of the massager 100.
[0081] The above are some implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
