Description

Technical Field

[0001] The invention relates to the technical field of massagers, in particular to a sucking massage device and a massager. Background Art

[0002] A sucking massager is a device designed for the health and pleasure enhancement of private parts, providing stimulation by simulating oral suction. This massager usually includes a nozzle that fits the sensitive area of ​​the human body and simulates the sucking feeling by creating negative / positive pressure to achieve a massage effect. The negative / positive pressure is usually generated by an electric pump or mechanical means to form a sealed environment between the nozzle and the skin, simulating a real sucking action through periodic negative and positive pressure.

[0003] In the prior art, as an example, US Pat. No. 9,763,851B2 discloses a stimulation device, wherein the device drives the bottom of the first chamber to perform telescopic movement through a driving unit to form a pressure field, and the driving unit is composed of a motor and an eccentric wheel, and the eccentric wheel is driven by the motor driving end to rotate, thereby causing the first chamber to periodically generate positive and negative pressures and form a sucking massage stimulation effect.

[0004] However, in the process of using the eccentric wheel drive, due to the limitation of the installation space, the eccentric wheel cannot be selected to be too large, and once the size of the eccentric wheel is selected, the driving force it can provide (the length of the bottom of the first chamber to drive the telescopic movement in the predetermined direction per unit time) is only related to the speed of the motor. And the motor is almost impossible to adjust so that it has two speeds in one rotation cycle. Therefore, when the motor speed is fixed, the method of providing negative pressure by driving the first chamber through the eccentric wheel provides a constant suction force, which is difficult to generate the suction force of the explosive force required by the user.

[0005] A major limitation of the eccentric drive in the sucking massager for generating positive and negative pressure is that it cannot change pressure quickly, making it difficult to achieve explosive pressure changes. This is because the rotation path of the eccentric is preset and continuous, and the follower moves linearly or cyclically with the shape and speed of the eccentric, resulting in a lack of rapid fluctuations in pressure changes.

[0006] In an eccentric-driven sucking massager, the generation of positive and negative pressure depends on the movement of the mechanical arm caused by the rotation of the eccentric, which inherently limits the rapid release or generation of pressure. The physical shape of the eccentric profile predefines the movement trajectory of the follower, so the speed and amplitude of the pressure change are strictly limited. Even if the eccentric speed increases, the rate and intensity of pressure change can only be changed within a certain range, and rapid or sudden high and low pressure switching cannot be achieved, which is a significant shortcoming for massage scenarios that require strong stimulation.

[0007] In addition, due to this limitation in the design of the eccentric drive system, when user needs tend to be more diverse and personalized massage modes, the traditional eccentric system is difficult to meet these needs. Users may seek to change the pressure quickly to simulate the changing human touch, but the eccentric system cannot effectively provide this flexibility and response speed due to its inherent power transmission method.

[0008] Therefore, although the eccentric wheel drive form has the advantages of simple mechanical structure and low cost when designing a sucking massager, it has obvious shortcomings in the pursuit of providing an intense and explosive massage experience. Summary of the invention

DETAILED DESCRIPTION

[0091] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0092] See also Figures 1 to 22 As shown, the specific embodiments provided by the present invention are as follows:

[0093] like Figures 1 to 4As shown, the first embodiment of the present invention provides a sucking massage device having a supporting unit 1, including:

[0094] A suction unit 2 having a massage opening 201 and a variable volume cavity 202, wherein the massage opening 201 is used to fit the skin surface of the massage part during massage;

[0095] A track unit 3 having a track body 301 and a position-limiting track component 302;

[0096] A sliding unit 4 having a sliding body 401 and a sliding assembly 402;

[0097] Drive unit 5;

[0098] The position-limiting track component 302 is connected to the sliding component 402 to form a first constraint, and the first constraint is used to limit the sliding component 402 and the position-limiting track component 302 to maintain a following state on the track line P0;

[0099] The support unit 1 connects the track unit 3 and the sliding unit 4 to form a second constraint, and the second constraint is used to allow the sliding unit 4 to have the freedom to make a circular motion relative to the track unit 3, and the axis of the circular motion is the central axis L0;

[0100] In this embodiment, the form of generating positive and negative pressure by eccentric wheel driving in the prior art is changed, with the aim of providing relatively fast fluctuating positive and negative pressure generation capability to form a relatively strong massage stimulation effect.

[0101] like Figure 8 As shown, specifically, the position-limiting track component 302 has a track line P0, and the track line P0 is a 3D track line that is closed at both ends. It should be noted that the track line P0 is located in a cylindrical surface S0, and the straight line L n The number of intersection points Mn that intersect with the trajectory line P0 is 1; among them, the straight line L n It is any straight line passing through the surface of the cylindrical surface S0 and parallel to the central axis L0 of the cylindrical surface S0. The specific form of the trajectory line P0 is a groove opened on the circumferential wall of the trajectory body 301, and the trajectory body 301 is specifically manifested as a cylindrical structure, and its circumferential wall is the surface of the cylindrical surface S0. In other words, the trajectory line P0 and the trajectory body 301 are integrally formed, and the trajectory line P0 constructs a continuous and closed-loop groove on the circumferential wall of the trajectory body 301, that is, the surface of the cylindrical surface S0, so that when the sliding body 401 is slidably connected in the groove, and when the driving unit 5 drives the sliding body 401 or the trajectory body 301 to rotate in the form of rotational drive, the sliding body 401 and the trajectory body 301 can slide relative to each other, and taking one of the bodies as a reference, the relative sliding of the other body is carried out along the trajectory line P0, thereby on the central axis LO In the direction of the massage opening 201, the other body (the sliding body 401 or the track body 301 that slides relatively) shows a periodic movement toward and away from the variable volume cavity 202, which eventually causes the positive and negative pressure changes inside the variable volume cavity 202. When the massage opening 201 contacts the part to be massaged 12, the change of the internal pressure of the variable volume cavity 202 (the generation of positive and negative pressure) forms a sucking massage effect on the part to be massaged 12.

[0102] The cylindrical surface S0 is a cylindrical surface because after the trajectory line P0 is formed along the cylindrical surface, it will show a smooth structure, thereby reducing the jamming of the structure, and then reducing the loss of the driving force (the force provided by the driving unit 5), ensuring the effective transmission of the driving force, and finally making the variable volume cavity 202 improve a stronger sucking massage effect.

[0103] Among them, positive pressure and negative pressure refer to relative atmospheric pressure or normal pressure calibration. Higher than atmospheric pressure or higher than the original state of the massage part 12 (not in contact with the sucking massage device) is defined as positive pressure, and vice versa is defined as negative pressure.

[0104] Among them, the 3D trajectory line should be understood as having a position difference along the direction of the central axis L0. For example, the 3D trajectory line is a closed-loop spiral. This position difference causes the sliding body 401 or the trajectory body 301 to move periodically toward and away from the variable-volume cavity 202, thereby promoting the above-mentioned positive and negative pressure changes.

[0105] The variable volume cavity 202 is controlled by the linear movement of the sliding body 401 or the track body 301 to form positive pressure and negative pressure.

[0106] As mentioned above, the track body 301, the sliding body 401, the variable volume cavity 202 and the driving unit 5 have the following two connection forms.

[0107] like Figure 7 As shown, firstly, the track body 301 is connected to the driving unit 5 , and the sliding body 401 is connected to the variable volume cavity 202 .

[0108] Specifically, the driving unit 5 (referring to the driving motor 501) rotates, driving the track body 301 to rotate, thereby causing the sliding body 401 to passively slide along the track line P0, and finally exhibiting a periodic movement toward or away from the variable volume cavity 202, and this movement causes the variable volume cavity 202 to experience changes in positive and negative pressure.

[0109] When the sliding body 401 moves toward the variable volume cavity 202, the sliding body 401 squeezes the variable volume cavity 202, the variable volume cavity 202 is deformed and the volume decreases, the air pressure increases, and a positive pressure change is formed. When the sliding body 401 moves away from the variable volume cavity 202, the sliding body 401 stretches the variable volume cavity 202, the variable volume cavity 202 is deformed and the volume increases, the air pressure decreases, and a negative pressure change is formed.

[0110] like Figure 5 As shown, secondly, the track body 301 is connected to the variable volume cavity 202 , and the sliding body 401 is connected to the driving unit 5 .

[0111] Specifically, the driving unit 5 (referring to the driving motor 501) rotates, driving the sliding body 401 to rotate. Due to the existence of the trajectory line P0, the trajectory body 301 passively makes a periodic motion toward or away from the variable volume cavity 202, and this motion causes the variable volume cavity 202 to experience changes in positive and negative pressure.

[0112] When the track body 301 moves toward the variable volume cavity 202, the track body 301 squeezes the variable volume cavity 202, the variable volume cavity 202 is deformed and the volume decreases, the air pressure increases, and a positive pressure change is formed. When the track body 301 moves away from the variable volume cavity 202, the track body 301 stretches the variable volume cavity 202, the variable volume cavity 202 is deformed and the volume increases, the air pressure decreases, and a positive pressure change is formed.

[0113] The above two connection forms can both convert the rotational motion of the driving unit 5 into linear motion, which is different from the eccentric wheel driving variable volume cavity 202 in the prior art in that:

[0114] First, the structural form of the sliding unit 4 and the track unit 3 provided in this embodiment can shorten the transmission path of the driving force (referring to the force provided by the driving unit 5) to a certain extent, thereby making the sliding unit 4 or the track unit 3 respond faster to the variable volume cavity 202 to generate positive pressure and negative pressure.

[0115] The specific reason is that, in the prior art, the driving force generated by the driving motor 501 causes the eccentric wheel to rotate, that is, the driving force is transmitted to the eccentric wheel. Subsequently, the eccentric wheel drives the follower (such as the follower connecting rod) to perform linear motion, that is, the driving force is transmitted to the follower. Finally, the follower drives the variable volume cavity 202 to deform, that is, the driving force is transmitted to the variable volume cavity 202.

[0116] In this embodiment, the driving force generated by the driving motor 501 directly acts on the sliding body 401 or the track body 301, that is, the driving force is transmitted to the sliding body 401 or the track body 301. Subsequently, the sliding body 401 or the track body 301 drives the variable volume cavity 202 to deform, that is, the driving force is transmitted to the variable volume cavity 202.

[0117] By comparison, it can be seen that the cooperation between the sliding unit 4 and the track unit 3 provided in this embodiment transmits the driving force more directly, and the transmission path is shorter, which reduces the consumption or loss of the driving force, and ultimately shows a massage stimulation effect with obvious fluctuations on the massage part 12.

[0118] Moreover, in the prior art, since it is applied to a handheld massager, the size and space are limited, and an eccentric wheel is used for driving, and the diameter of the eccentric wheel determines the length of the compression stroke and the stretching stroke of the variable volume chamber 202. On the basis of limited size and space, the diameter of the eccentric wheel cannot be very large, which leads to limited compression and stretching of the variable volume chamber 202, and finally a weak massage stimulation effect is shown. In this embodiment, the slope of the trajectory line P0 can be customized. For example, if a user expects a stronger massage stimulation effect, the slope of the trajectory line P0 can be increased, and if a user expects a milder massage stimulation effect, the slope of the trajectory line P0 can be reduced. Moreover, the stretching and compression of the variable volume chamber are no longer controlled by the diameter size of the eccentric wheel, so that a product function with a strong massage stimulation effect can be designed under the size limit of the handheld massager.

[0119] Secondly, the structural form of the sliding unit 4 and the track unit 3 provided in this embodiment can avoid the change of the transmission path of the driving force to a certain extent, thereby greatly slowing down the attenuation of the driving force, and finally enabling the variable volume cavity 202 to provide a more significant massage stimulation effect on the massage part 12.

[0120] The specific reason is that in the prior art, the axis of the drive motor 501 is perpendicular to the axis of the variable volume chamber 202, that is, the transmission path of the driving force from the drive motor 501 to the eccentric wheel is also perpendicular to the transmission path of the driving force from the eccentric wheel to the driven member. It can be visualized as follows: the driving force needs to be transmitted along two mutually perpendicular straight lines, which causes transmission loss of the driving force, resulting in the driving force transmitted to the variable volume chamber 202 being attenuated. Ultimately, the massage stimulation effect of the variable volume chamber 202 on the massage area 12 is significantly reduced; at the same time, since the vertical design of the drive motor and the variable volume chamber must be ensured, it cannot be used in an environment with limited assembly space.

[0121] In this embodiment, the axis of the driving unit 5 and the axis of the sliding body 401 or the track body 301 are in the same straight line, that is, the driving force generated by the driving motor 501 can be directly transmitted to the sliding body 401 or the track body 301, and finally the driving force is transmitted to the variable volume cavity 202 in a relatively short time in the form of less driving force loss, so that the variable volume cavity 202 provides a stronger massage stimulation effect on the massage part 12.

[0122] On the basis of the above, the following points need to be considered:

[0123] First, the sliding body 401 and the track body 301 need to have a large degree of relative movement. For example, if the sliding body 401 and the track body 301 rotate synchronously, the two will not passively move along the track line P0, and thus cannot cause the variable volume cavity 202 to deform.

[0124] Secondly, after the above conditions are met, it is necessary to ensure the connectivity between the sliding body 401 and the track body 301. On the one hand, it is necessary to ensure that the sliding body 401 and the track body 301 do not disengage from each other during synchronous rotation. On the other hand, it is necessary to ensure that the synchronous rotation of the two can be efficiently converted into the linear motion of a certain body, so as to ensure that the deformation response speed of the variable volume cavity 202 is improved.

[0125] Based on this, the first constraint and the second constraint are added.

[0126] like Figures 5 and 6 As shown, the first constraint is formed by the connection between the sliding assembly 402 and the position-limiting track assembly 302. Specifically, the sliding assembly 402 is connected to the sliding body 401 and the position-limiting track assembly 302, respectively, so as to ensure that the sliding assembly 402 (and the sliding body 401) and the position-limiting track assembly 302 (and the track body 301) maintain a following state on the track line P0, that is, the two will not be separated, so as to ensure the efficiency of converting rotation into linear motion.

[0127] The second constraint is formed by the support unit 1. Specifically, the support unit 1 is in the form of a slide groove 101 and a slider 102. The slide groove 101 is formed on the inner wall surface of the housing 6, and the slider 102 is connected to the outer wall surface of the sliding body 401. The slide groove 101 and the slider 102 form a sliding fit, and the slide groove 101 is along the central axis L. O The second constraint is used to allow the sliding unit 4 to have the freedom to make circular motion relative to the track unit 3, and the axis of the circular motion is the central axis L0. That is, the sliding unit 4 can rotate relative to the track unit 3, thereby avoiding the problem that the two rotate synchronously and the rotation cannot be converted into linear motion.

[0128] The second embodiment of the present invention provides a sucking massage device, and based on the first embodiment, the track body 301 is a barrel-shaped structure, and the position-limiting track component 302 is connected to or formed on the inner wall of the barrel-shaped structure; or,

[0129] The track body 301 is a columnar structure, and the position-limiting track assembly 302 is connected to or formed on the outer wall of the columnar structure.

[0130] On the basis of the above, two assembly forms are provided: a sliding body 401 and a track body 301 .

[0131] like Figures 5 to 7 As shown, the limiting track component 302 is a groove 3021 connected to or formed on the track body 301, and the sliding component 402 is a positioning pin 4021 connected to or formed on the sliding body 401, and the positioning pin 4021 is matched and limited in the groove 3021.

[0132] Specifically, one end of the positioning pin 4021 is connected to the sliding body 401, and the other end is slidably connected in the groove 3021. The sliding of the positioning pin 4021 in the groove 3021 causes the sliding body 401 to form a linear motion, or the positioning pin 4021 causes the track body 301 to form a linear motion through the groove 3021, thereby driving the variable volume cavity 202 to undergo changes in positive pressure and negative pressure.

[0133] Among them, the limiting track component 302 is a convex rib 3022 connected or formed on the track body 301, and the sliding component 402 is a C-shaped slot card 4022 connected or formed on the sliding body 401, and the C-shaped slot card 4022 is clamped and limited on the convex rib 3022.

[0134] Specifically, the convex rib 3022 is slidably connected to the C-shaped slot card 4022. The convex rib 3022 slides in the C-shaped slot card 4022 to cause the sliding body 401 to form a linear motion, or the convex rib 3022 causes the track body 301 to form a linear motion through the C-shaped slot card 4022, thereby driving the variable volume cavity 202 to change between positive pressure and negative pressure.

[0135] like Figures 8 to 11 As shown, the third embodiment of the present invention provides a sucking massage device, and based on the previous embodiment, the trajectory line P0 includes:

[0136] An adsorption rapid drop section 701 having a starting end J0 and an end J1;

[0137] An adsorption maintaining section 702 having a starting end W0 and an end W1;

[0138] A pulse pump gas section 703 having a starting end C0 and an end C1;

[0139] Among them, the starting end J0 is smoothly connected to the end C1, the end J1 is smoothly connected to the starting end W0, and the end W1 is smoothly connected to the starting end C0;

[0140] Among them, J f >W f , C f >W f , the J f , W f and C f They are the slopes of the adsorption speed drop section 701, the adsorption maintenance section 702 and the pulse pump gas section 703 respectively, and the slope is the ratio of the projection length of the unit trajectory section P1 on the trajectory line P0 on the central axis L0 to the central angle α of its projection arc on the circumference of the cylindrical surface S0.

[0141] It should be understood that the end of a certain section is at the same position as the beginning of the next section. For example, the end J1 of the adsorption speed drop section 701 and the beginning W0 of the adsorption maintenance section 702 are at the same position, the end W1 of the adsorption maintenance section 702 and the beginning C0 of the pulse pump gas section 703 are at the same position, and the end C1 of the pulse pump gas section 703 and the beginning J0 of the adsorption speed drop section 701 are at the same position, thereby forming a closed trajectory line P0 structure.

[0142] In this embodiment, it is further found that if during use, the contact between the opening of the variable volume cavity and the skin of the massage area is not strictly sealed, that is, there is an air leakage gap, this will significantly reduce the adsorption massage effect formed by the negative pressure; and when the air leakage gap is very large, it may even lead to the complete failure of the negative pressure suction effect.

[0143] Based on this, the present embodiment hopes to solve the above-mentioned problem, so that when the massager is used, even if the operation is not standardized so that there is a large gap between the massage opening 201 and the part to be massaged 12, it can still provide the user with a certain adsorption massage stimulation.

[0144] Therefore, the trajectory line P0 is divided into an adsorption rapid drop section 701 , an adsorption maintaining section 702 and a pulse pumping section 703 .

[0145] Among them, the J of the adsorption rapid drop section 701 f The sliding body 401 and the track body 301 are relatively large, so that when the sliding body 401 and the track body 301 are slidingly matched in this section, the rate of change of the linear motion of the sliding body 401 or the track body 301 is significantly improved, so that the sliding body 401 or the track body 301 causes the negative pressure of the variable volume cavity 202 to change in a relatively short period of time, and finally the variable volume cavity 202 exhibits a significant adsorption massage stimulation effect.

[0146] Furthermore, since the negative pressure is generated at a faster speed and for a shorter time, in order to ensure that the period of the adsorption massage stimulation effect on the massaged part 12 is increased, the adsorption maintenance section 702 is increased. And the slope W of the adsorption maintenance section 702 is f The purpose is to increase the action time of the sliding body 401 or the track body 301 in this section, and finally increase the time that the variable volume cavity 202 maintains the negative pressure state, thereby increasing the time that the adsorption massage stimulation effect acts on the massaged part 12.

[0147] Furthermore, the slope C of the pulse pump gas section 703 is f When the sliding body 401 or the track body 301 slides in this section, the sliding body 401 or the track body 301 moves linearly toward the variable volume cavity 202, so that the variable volume cavity 202 enters a positive pressure state, and finally provides a corresponding massage stimulation effect to the massage part 12. Of course, the duration of the positive pressure state and the speed of forming the positive pressure state are relatively moderate, so as to form a significant difference with the duration and speed of the negative pressure state, and finally ensure that the user can feel the massage stimulation effect brought by the clearly distinguished positive and negative pressures.

[0148] Among them, J f >m*W f ;

[0149] Among them, 3≥m≥1.5.

[0150] The reason for setting this formula is that when the J of the adsorption speed drop section 701 f The slope W of the adsorption maintenance section 702 is significantly greater than 1.5 times, 2 times, or 3 times f The rate of change of the linear motion of the sliding body 401 or the track body 301 in the negative pressure formation stage is significantly higher than the rate of change in the negative pressure maintenance stage, and the massage part 12 can feel the significant difference in pressure change. Specifically, the negative pressure formation stage is the stage in which the variable volume chamber 202 inhales gas from the outside, and the massage stimulation effect felt by the user at this stage is relatively strong and obvious, while the negative pressure maintenance stage is after the negative pressure formation stage, and the variable volume chamber 202 is required to maintain the current negative pressure for a certain period of time at this stage, thereby ensuring that the adsorption massage stimulation effect formed by the negative pressure prolongs the effective action time of the massage part 12, and finally enables the user to feel a stronger massage stimulation effect.

[0151] like Fig.12 As shown, the fourth embodiment of the present invention provides a sucking massage device, and based on the previous example, α j ≤70°, 100°≤α w ≤220°, α c ≤70°;

[0152] Among them, αj , α w and α c J f , W f and C f The central angle of the arc projected by the trajectory segment on the circumference of the cylindrical surface S0.

[0153] In this embodiment, as mentioned above, the present application expects that the massage stimulation effect formed by the negative pressure of the variable volume cavity 202 is significantly greater than the massage stimulation effect formed by the positive pressure.

[0154] Based on this, in addition to the significant difference in the rate of change of the linear motion of the sliding body 401 or the track body 301, the time for forming the negative pressure stage can also be increased. That is, the negative pressure stage is formed at a faster rate and lasts for a longer time, which can ensure that the user receives a stronger and longer period of adsorption massage stimulation effect.

[0155] Therefore, when J f , W f and C f The center angles α of the arcs projected on the circumference of the cylindrical surface S0 of the trajectory segments, namely the adsorption speed drop segment 701, the adsorption maintenance segment 702 and the pulse pump gas segment 703, are j , α w and α c represents the stroke of each section. The larger the central angle, the larger the stroke of this section, that is, the longer the period of positive pressure or negative pressure formed by the variable volume cavity 202 being controlled by the sliding body 401 or the track body 301 moving in this section. As mentioned above, this embodiment expects that the negative pressure state period of the variable volume cavity 202 will increase, and the rate of change of the negative pressure state will be faster. Therefore, the central angle α of the adsorption speed drop section 701 is set to j The value is set within 100° to 220°. For example, 100°, 150°, 200°, 220°. As long as the center angle α of the adsorption drop section 701 is guaranteed j It is found that during use, since the central angle of the adsorption speed drop section 701 is relatively large, the movement period of the sliding body 401 or the track body 301 in this section is relatively long, and, as mentioned above, the sliding body 401 and the track body 301 have a large change rate in this section, so that the variable volume cavity 202 forms a strong and significant adsorption massage stimulation effect, thereby ensuring that the user feels obvious physical stimulation.

[0156] Of course, since the various parameters (duration and change rate) of the variable-volume chamber 202 forming a negative pressure state are significantly different from the various parameters forming a positive pressure state, the switching between the negative pressure state and the positive pressure state has a strong contrast, and the user can further form a strong massage stimulation effect by feeling this strong contrast.

[0157] like Figures 13 to 16 As shown, the fifth embodiment of the present invention provides a sucking massage device, and based on the previous embodiment, it has:

[0158] A first elastic unit 801 and / or a second elastic unit 802;

[0159] The first elastic unit 801 is disposed on the wall of the position-limiting track component 302 away from the variable volume cavity 202; and stores elastic energy when rotating from the starting end W0 to the end W1 on the adsorption maintaining section 702 of the track line P0, and starts to release the elastic energy at the starting end C0;

[0160] The second elastic unit 802 is arranged on the wall of the limit track component 302 close to the variable volume cavity 202; and stores energy near the end C1 on the pulse pump gas section 703 of the track line P0, and starts to release elastic energy near the starting end J0 on the adsorption speed drop section 701.

[0161] In this embodiment, it is further discovered that when the sliding body 401 or the track body 301 forms relative sliding movement along the track line P0, the sliding body 401 or the track body 301 will collide with the track line P0 (specifically, the groove 3021 formed by the limiting track component 302 along the track line P0), especially at the end positions of the adsorption speed drop section 701, the adsorption maintenance section 702 and the pulse pump gas section 703. This collision will significantly consume the driving force, thereby weakening the effect of the driving force on the variable volume cavity 202.

[0162] Based on this, a first elastic unit 801 and a second elastic unit 802 are added.

[0163] Among them, in the stage of transition from the adsorption maintenance section 702 to the pulse pump gas section 703, the present embodiment expects that the first elastic unit 801 can absorb the energy of the adsorption maintenance section 702, which refers to the energy generated by the collision between the sliding body 401 or the track body 301 and the track line P0 (specifically, the groove 3021 formed by the limit track component 302 along the track line P0), especially the energy at the end W1 of the adsorption maintenance section 702 is absorbed and stored. Then the absorbed and stored energy begins to be released at the starting end C0 position of the pulse pump gas section 703 to help the sliding body 401 or the track body 301 have higher kinetic energy in the pulse pump gas section 703, thereby causing the variable volume cavity 202 to undergo a larger deformation, thereby ensuring that it has sufficient thrust on the gas, and then forming an explosive massage stimulation effect under a positive pressure state.

[0164] Correspondingly, in the stage of transition from the pulse pump gas section 703 to the adsorption speed drop section 701, the present embodiment expects that the second elastic unit 802 can absorb the energy of the pulse pump gas section 703, which refers to the energy generated by the collision between the sliding body 401 or the track body 301 and the track line P0 (specifically, the groove 3021 formed by the limit track component 302 along the track line P0), especially the energy at the end C1 of the pulse pump gas section 703 is absorbed and stored. Then the absorbed and stored energy begins to be released at the starting end J0 position of the adsorption speed drop section 701, so as to help the sliding body 401 or the track body 301 have higher kinetic energy in the adsorption speed drop section 701, thereby causing the variable volume cavity 202 to undergo a larger deformation, thereby ensuring that it has sufficient suction force on the gas, and then forming an explosive massage stimulation effect under negative pressure.

[0165] In a specific implementation, the first elastic unit 801 and the second elastic unit 802 are springs, which absorb and release elastic energy by deforming.

[0166] like Figures 1 to 4 As shown, the sixth embodiment of the present invention provides a sucking massage device, and based on the previous embodiment, the sucking unit 2 has:

[0167] The first deformation surface 2021;

[0168] The first deformation surface 2021 is a wall surface connecting the variable volume cavity 202 and the sliding body 401;

[0169] Or, the first deformation surface 2021 is a wall surface connecting the variable volume cavity 202 and the track body 301;

[0170] Furthermore, the first deformable surface 2021 is elastic and can be deformed.

[0171] In this embodiment, the sliding body 401 or the track body 301 is connected to the first deformation surface 2021 to cause the first deformation surface 2021 to deform to form a negative pressure and a positive pressure state. Of course, the remaining wall surfaces of the variable volume cavity 202 can be made of a hard material, that is, only the first deformation surface 2021 needs to be made of an elastic material, and the remaining wall surfaces of the variable volume cavity 202 can also use the same or different elastic materials as the first deformation surface 2021.

[0172] The seventh embodiment of the present invention provides a sucking massage device, and based on the previous embodiment, the sucking unit 2 has:

[0173] The first deformation surface 2021;

[0174] Wherein, the first deformation surface 2021 is the bottom surface of the variable volume cavity 202;

[0175] The second deformation surface 2022;

[0176] Wherein, the second deformation surface 2022 is the side wall surface of the variable volume cavity 202;

[0177] Furthermore, the second deformation surface 2022 is elastic.

[0178] In this embodiment, there is also a second deformation surface 2022. The reason is that if the variable volume cavity 202 has only one deformation surface, its ability to inhale and exhaust gas will be weakened, thereby significantly reducing the massage stimulation effect. Furthermore, in order to ensure that the massage opening 201 can form a relatively good contact with the massage part 12 to reduce the generation of the gap between the two, thereby ensuring the massage stimulation effect, the second deformation surface 2022 is further added.

[0179] When the massage opening 201 contacts the area to be massaged 12, the second deformation surface 2022 can be compressed so that the massage opening 201 can be closely attached to the area to be massaged 12 without causing excessive pressure on the area to be massaged 12. On the basis of ensuring that the gap between the massage opening 201 and the area to be massaged 12 is reduced, the ability of the variable volume cavity 202 to inhale and exhaust gas is further increased.

[0180] In one specific embodiment, the variable volume cavity 202 is made of silicone.

[0181] In a specific implementation, the first deformation surface 2021 of the variable volume cavity 202 is made of silicone, and the remaining wall surfaces are made of hard materials.

[0182] like Figures 17 to 21 As shown, in a specific embodiment, the variable volume cavity 202 can present various shapes. For example, the cross section presents a funnel shape, a regular trapezoid, an inverted trapezoid, etc. For example, the massage opening 201 of the variable volume cavity 202 can present a circular, quasi-circular, or two interconnected circular structures.

[0183] In a specific embodiment, at least along the first direction, the diameter of the variable volume cavity 202 increases gradually;

[0184] like Fig.13 As shown, the first direction is: along the central axis L0, and is the direction from the suction unit 2 to the track unit 3.

[0185] Among them, the diameter of the variable-volume cavity 202 increases gradually. Since the bottom of the variable-volume cavity 202 (referring to the cavity of the variable-volume cavity 202 close to the first deformation surface 2021) is deformed, the volume of the variable-volume cavity 202 becomes smaller, and the air pressure increases. The flow path of the gas is from the bottom of the variable-volume cavity 202 to the massage opening 201. Since the diameter of the massage opening 201 is small and the bottom diameter of the variable-volume cavity 202 is large, when the gas flow rate is constant, due to the small diameter of the massage opening 201, the air pressure at this position will increase, thereby increasing the stimulation to the massage area.

[0186] like Figures 5 to 7 As shown, the eighth embodiment of the present invention provides a sucking massage device, and based on the previous embodiment, includes:

[0187] Connecting unit 9;

[0188] Wherein, the connecting unit 9 is disposed between the sliding body 401 and the variable volume cavity 202;

[0189] Alternatively, the connection unit 9 is disposed between the track body 301 and the variable volume cavity 202 .

[0190] In this embodiment, a connecting unit 9 is included.

[0191] The reason is that, in this embodiment, the sliding body 401 or the track body 301 is expected to be connected to the variable volume cavity 202. In the stage of forming the negative pressure state of the variable volume cavity 202, the tensile deformation of the variable volume cavity 202 is increased, thereby ensuring that the upper limit of the negative pressure is further increased, and finally showing a massage stimulation effect that is obviously different from that provided by the positive pressure state.

[0192] like Figures 5 to 7 As shown, in a specific embodiment, the connecting unit 9 includes:

[0193] A coupling part 1 901 and a coupling part 2 902;

[0194] Wherein, the coupling part 901 is connected to the sliding body 401 or the track body 301;

[0195] Wherein, the second coupling part 902 is connected to the variable volume cavity 202;

[0196] Furthermore, the coupling part 1 901 and the coupling part 2 902 are clearance-matched.

[0197] The coupling part 1 901 is a spherical structure, and the coupling part 2 902 is a ball groove structure, and the two are slidably matched and clearance matched. When the sliding body 401 or the track body 301 makes a linear motion away from the variable volume cavity 202, the coupling part 1 901 pulls the coupling part 2 902 to move, thereby causing the variable volume cavity 202 to undergo a larger tensile deformation, thereby forming a larger negative pressure adsorption effect.

[0198] like Fig.13 As shown, the ninth embodiment of the present invention provides a sucking massage device, and based on the previous embodiment, the sucking massage device has a handheld end D1 and a working end D2;

[0199] Wherein, the driving unit 5 is assembled to the handheld terminal D1;

[0200] The variable volume cavity 202 is assembled to the working end D2.

[0201] In this embodiment, the handheld end D1 is used for holding by a user, and the working end D2 is used for assembling the variable volume cavity 202 to form positive pressure and negative pressure massage stimulation effects on the massage part 12.

[0202] like Figures 13 to 22 As shown, the tenth embodiment of the present invention provides a massager 10, comprising:

[0203] A sucking massage device as described in any one of the above embodiments.

[0204] The driving unit 5 is connected to an electric control module 11 , such as a rechargeable battery.

[0205] The specific use process is that the user holds the massager 10, aligns the massage opening 201 of the variable volume cavity 202 with the part to be massaged 12, and makes the two come into contact. The driving unit 5 is started to rotate its driving end, thereby driving the sliding body 401 or the track body 301 to rotate, thereby making the track body 301 or the sliding body 401 move linearly away from or toward the variable volume cavity 202, so that the variable volume cavity 202 undergoes compression deformation and tension deformation, and finally forms a positive pressure and negative pressure state in the variable volume cavity 202, providing a massage stimulation effect for the part to be massaged 12.

[0206] Among them, the driving unit 5 is a motor 501, the sliding body 401 is a barrel-type structure, the upper end of the barrel-type structure is connected to the bottom surface of the variable volume cavity 202 (that is, the first deformation surface 2021) through the connecting unit 9, and the sliding component 402 is a positioning pin 4021, and the end of the positioning pin 4021 is slidably connected to the limiting track component 302 (having a groove 3021 with a track line P0) of the track body 301 (columnar structure).
