Description

Technical Field

[0001] This utility model relates to the field of massager technology, specifically to a massager with an adjustable massage head height. Background Technology

[0002] A massager is a device that can massage the human body to relax muscles. As people's living standards improve, various massagers have appeared on the market.

[0003] Application publication number CN102218009A discloses a suction cup massager, which specifically discloses a housing, a vibration component, and an elastic vacuum suction cup. The vibration component includes a motor and a vibrating block eccentrically fixed on the motor shaft. The motor is fixed inside the housing, and the vacuum suction cup is fixed below the housing. The vacuum suction cup has a top surface, a bottom surface, and a vacuum cavity extending upward from the bottom surface. When the vacuum suction cup is pressed onto the massage area, the gas in the vacuum cavity is discharged. When the vacuum suction cup is released, the vacuum suction cup rebounds, causing the bottom surface to adhere to the massage area.

[0004] However, there is still room for improvement in the aforementioned suction cup massager. For example, since the height of the vibration component is not adjustable, it cannot create different pressure levels on the skin, meaning it cannot meet the massage needs of different people.

[0005] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a massager with an adjustable massage head, wherein the massage head is height adjustable to create different massage intensities on the skin to meet the massage needs of different people.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A massager with an adjustable massage head height includes an outer shell with a lower opening, a fixed bracket mounted inside the outer shell, a rotary drive motor mounted on the fixed bracket, a massage assembly facing downward and mounted on the output shaft of the rotary drive motor, a battery mounted on the fixed bracket for providing power, and a circuit board mounted on the fixed bracket and serving as a control center. The massage assembly includes an upper massage frame mounted on the output shaft of the rotary drive motor, a lower massage frame adjustable up and down and snapped into the upper massage frame, and massage heads mounted on the lower massage frame. The upper massage frame has a lower opening; at least two inwardly extending rods are provided inside the upper massage frame; and massage heads are mounted on the lower massage frame. The outer wall of the frame is provided with at least two track grooves, each composed of multiple continuous track segments, for inserting the insertion rod. Each track groove has an upper and a lower positioning port, distributed vertically, for positioning the insertion rod. Both the upper and lower positioning ports face downwards. A spring is also provided between the upper and lower massage frames to ensure the lower massage frame maintains a downward tendency. Twisting the lower massage frame allows the insertion rod to move within the track grooves. When the insertion rod is engaged in the upper positioning port, the height of the massage head is adjusted upwards; when the insertion rod is engaged in the lower positioning port, the height of the massage head is adjusted downwards.

[0009] Furthermore, the massage head is detachably mounted on the lower massage frame, thereby allowing for easy replacement of massage heads of different styles or functions.

[0010] Furthermore, a first magnet is provided on the lower massage frame; a second magnet is provided on the massage head to cooperate with the first magnet; the massage head can be positioned on the lower massage frame by the magnetic attraction between the first magnet and the second magnet. This arrangement facilitates the assembly and disassembly of the massage head.

[0011] Furthermore, a limiting protrusion is provided on the outer wall of the upper massage frame, surrounding it; a limiting groove is provided on the fixed bracket for correspondingly embedding the limiting protrusion. These features improve the stability of the upper massage frame during rotation.

[0012] Furthermore, the outer shell includes a matching silicone sleeve and a PC transparent shell; the fixing bracket includes a mounting part and an arc-shaped cover that is connected to the top of the mounting part and is convex upward; the silicone sleeve is fitted onto the outer wall of the arc-shaped cover; the upper end of the PC transparent shell is fitted onto the outer wall of the mounting part and engages with the mounting part; the rotary drive motor is mounted on the mounting part.

[0013] Furthermore, an annular gap is left between the top surface of the mounting part and the bottom surface of the arc-shaped cover; a retaining strip extends inward from the bottom periphery of the silicone sleeve, corresponding to the annular gap, and the retaining strip can be matched and locked in the annular gap. The above arrangement can improve the sealing performance of the massager.

[0014] Furthermore, at least two inverted L-shaped positioning slots with open lower ends are provided on the outer walls of the mounting portion; at least two positioning pins for cooperating with the positioning slots are provided on the upper inner wall of the PC transparent shell; each positioning pin can be positioned by correspondingly engaging one of the positioning slots. The cooperation between the positioning slots and positioning pins facilitates the installation and removal of the PC transparent shell.

[0015] Furthermore, a sealing ring for improving sealing is provided between the outer wall of the mounting part and the inner wall of the PC transparent shell.

[0016] Furthermore, the outer shell also includes a silicone ring; the silicone ring is fitted onto the bottom of the PC transparent shell. By incorporating the silicone ring, its elasticity allows the outer shell to fit more closely to the skin.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention utilizes a rotary drive motor to easily rotate the massage head, enabling it to massage the skin. Furthermore, the cooperation between the insert rod and the track groove allows the massage head to rotate synchronously when the lower massage frame is rotated. The upper or lower position positioning port can be used to position the height of the insert rod, thus adjusting the height of the massage head. Additionally, by adjusting the height of the massage head, different massage intensities can be applied to the skin to suit the needs of different individuals. Attached Figure Description

[0028] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely exemplary and does not limit the scope of protection of the utility model.

[0029] like Figures 1-7 As shown, a massager with an adjustable massage head height includes an outer shell 1 with a lower opening, a fixed bracket 2 installed inside the outer shell 1, a rotary drive motor 3 installed on the fixed bracket 2, a massage assembly 4 facing downward and installed on the output shaft of the rotary drive motor 3, a battery 9 installed on the fixed bracket 2 for providing power, and a circuit board 5 installed on the fixed bracket 2 and serving as the control center; the massage assembly 4 includes an upper massage frame 41 installed on the output shaft of the rotary drive motor 3, a lower massage frame 42 that is adjustable up and down and snapped into the upper massage frame 41, and a massage head 43 installed on the lower massage frame 42.

[0030] like Figures 1-7As shown, specifically, the upper massage frame 41 is open at the lower end; at least two inwardly extending insertion rods 44 are provided on the inner side of the upper massage frame 41; at least two track grooves 45, each composed of multiple continuous track segments, are provided on the outer wall of the lower massage frame 42 for inserting the insertion rods 44. Each track groove 45 has an upper position positioning port 46 and a lower position positioning port 47, which are distributed vertically and used for positioning the insertion rods 44. The openings of the upper position positioning port 46 and the lower position positioning port 47 are both downward. In addition, the interval between the upper position positioning port 46 and the lower position positioning port 47 should not be too large. A spring 48 is also provided between 41 and the lower massage frame 42 so that the lower massage frame 42 can always maintain a downward movement tendency. Therefore, by using the spring 48, it can be ensured that the insertion rod 44 can always maintain the positioning state after it is inserted into the upper position positioning port 46 or the lower position positioning port 47, and it is not easy to loosen. By twisting the lower massage frame 42, the insertion rod 44 can be moved in the track groove 45. Specifically, when the insertion rod 44 is inserted into the upper position positioning port 46, the height of the massage head 43 is adjusted upward; and when the insertion rod 44 is inserted into the lower position positioning port 47, the height of the massage head 43 is adjusted downward.

[0031] Therefore, this invention utilizes a rotary drive motor 3 to easily rotate the massage head 43, enabling it to massage the skin. Furthermore, the cooperation between the insertion rod 44 and the track groove 45 allows the massage head 43 to rotate synchronously when the lower massage frame 42 is rotated. The upper position positioning port 46 or lower position positioning port 47 can be used to position the height of the insertion rod 44, thus achieving the effect of positioning the height of the massage head 43, thereby enabling height adjustment. Additionally, by adjusting the height of the massage head 43, different massage intensities can be applied to the skin to meet the massage needs of different individuals.

[0032] In this embodiment, the outer shell 1 is a trumpet shape that gradually increases in size from top to bottom, and its top is an upward-convex arc shape.

[0033] like Figures 3-7 As shown, regarding the installation method of spring 48, the upper end of spring 48 abuts against the top surface of the inner cavity of the upper massage frame 41, and the lower end of spring 48 abuts against the bottom surface of a groove on the top of the lower massage frame 42, thereby making spring 48 less prone to loosening.

[0034] like Figures 3-7 As shown, preferably, the massage head 43 is detachably mounted on the lower massage frame 42, thereby making it easy to replace massage heads of different styles or functions so that the massager can provide different massage effects. In addition, since the massage head 43 can be detached, it can also be easily replaced after the massage head 43 is damaged.

[0035] like Figures 3-5 As shown, for the detachable connection of the massage head 43, a first magnet 6 is provided on the lower massage frame 42; a second magnet 7 that cooperates with the first magnet 6 is provided on the massage head 43; the massage head 43 can be positioned on the lower massage frame 42 by the magnetic attraction between the first magnet 6 and the second magnet 7. Therefore, in use, simply pull the massage head 43 outward to separate the first magnet 6 and the second magnet 7, thus achieving the purpose of detaching the massage head 43. When installing the massage head 43, simply insert the massage head 43 directly into the corresponding position on the lower massage frame 42 and ensure that the first magnet 6 and the second magnet 7 are magnetically attracted to each other to complete the installation of the massage head 43. Of course, the newly replaced massage head 43 also needs to be equipped with a magnet that cooperates with the second magnet 7.

[0036] like Figures 3-7 As shown, to improve the stability of the massage assembly 4, a limiting protrusion 49 is provided on the outer wall of the upper massage frame 41, surrounding the upper massage frame 41; a limiting groove 50 is provided on the fixed bracket 2 for correspondingly embedding the limiting protrusion 49. Therefore, by utilizing the cooperation between the limiting protrusion 49 and the limiting groove 50, when the upper massage frame 41 rotates, the limiting protrusion 49 will rotate in the limiting groove 50, thereby preventing the upper massage frame 41 from swaying, and consequently preventing the lower massage frame 42 and the massage head 43 from swaying.

[0037] like Figures 1-5 As shown, in this embodiment, the outer shell 1 includes a matching silicone sleeve 101 and a PC transparent shell 102; the fixing bracket 2 includes a mounting part 21 and an upwardly convex arc-shaped cover 22 connected to the top of the mounting part 21, and screws can be used to connect the top of the mounting part 21 and the arc-shaped cover 22; the silicone sleeve 101 is fitted onto the outer wall of the arc-shaped cover 22; the upper end of the PC transparent shell 102 is fitted onto the outer wall of the mounting part 21 and snaps into the mounting part 21; the rotary drive motor 3 is mounted on the mounting part 21. Therefore, by providing the silicone sleeve 101 on the arc-shaped cover 22, the surface feel of the massager can be improved. In addition, the PC transparent shell 102 allows the user to easily observe the internal condition of the massager, such as whether the massage head 43 is in contact with the target area.

[0038] Specifically, the limiting groove 50 is provided on the mounting part 21.

[0039] like Figures 1-5As shown, in this embodiment, there is an annular gap 23 left between the top surface of the installation part 21 and the bottom surface of the arc-shaped cover 22; a clamping strip 103 corresponding to the annular gap 23 extends inward from the bottom of the silicone sleeve 101 around its perimeter, and the clamping strip 103 can be clamped in the annular gap 23 in a matching manner. Therefore, by clamping the clamping strip 103 in the annular gap 23, the sealing performance between the installation part 21 and the arc-shaped cover 22 can be improved, and moreover, it can also be used to position the silicone sleeve 101.

[0040] As Figures 1-5 shown, in this embodiment, at least two inverted L-shaped positioning card slots 24 with open bottoms are provided on the outer wall around the installation part 21. More specifically, as Figure 4 shown, the shape of the positioning card slot 24 is similar to the shape of "厂"; at least two positioning card posts 104 for cooperating with the positioning card slots 24 are provided on the inner wall at the upper end of the PC transparent shell 102; each positioning card post 104 can be positioned by being correspondingly clamped in a positioning card slot 24. Therefore, by the cooperation of the positioning card posts 104 and the positioning card slots 24, the PC transparent shell 103 can be more stably clamped on the installation part 21, and this design can facilitate the installation of the PC transparent shell 102; when installing the PC transparent shell 102, align the positioning card posts 104 with the openings of the positioning card slots 24 and then push it upward to the preset position, and then rotate the PC transparent shell 102, so that the positioning card posts 104 move to the ends of the positioning card slots 24, thus completing the installation of the PC transparent shell 103. In addition, in order to further improve the stability of the PC transparent shell 103, a protrusion (not marked in the figure) can also be provided at the end of the positioning card slot 24, and a groove (not marked in the figure) can be provided at the corresponding position of the positioning card post 104, so that when the positioning card post 104 moves to the end of the positioning card slot 24, the protrusion and the groove can be engaged with each other, thereby making it difficult for the positioning card post 104 to protrude outwards, that is, it is beneficial to ensure the stability of the PC transparent shell 102.

[0041] As Figures 1-5 shown, at the same time, in order to improve the sealing performance between the PC transparent shell 102 and the installation part 21, a sealing ring 25 for improving the sealing performance can also be provided between the outer wall of the installation part 21 and the inner wall of the PC transparent shell 102.

[0042] As Figures 1-5 shown, preferably, the outer shell 1 further includes a silicone ring 105; the silicone ring 105 is sleeved on the bottom of the PC transparent shell 102 in a matching manner. Therefore, by providing the silicone ring 105, the outer shell 1 can be more closely fitted to the skin by using its deformation elasticity.

[0043] As Figures 1-2As shown, preferably, a button assembly 8 electrically connected to the circuit board 5 is also provided on the outer casing 1. Specifically, the button assembly 8 includes an acceleration button and a deceleration button for controlling the rotational speed of the rotary drive motor 3. In use, a short press of either the acceleration or deceleration button will accelerate or decelerate the rotary drive motor 3 accordingly, creating different massage effects. Furthermore, a long press of the acceleration button will activate the massager, and a long press of the deceleration button will deactivate the massager.

[0044] Preferably, a magnetic charging interface (not shown in the figure) electrically connected to the circuit board 5 can also be provided on the outer casing 1 to facilitate charging of the battery 9. Since magnetic charging is a convenient method, it also improves the ease of charging the massager. Furthermore, since magnetic charging is existing technology, it will not be elaborated upon here.

[0045] Of course, the rotary drive motor 3 is also electrically connected to the circuit board 5.

[0046] Preferably, in order to facilitate the adhesion of the outer shell 1 to the skin, the fixing bracket 2 is also provided with an air pump 10. Specifically, the air pump 10 is provided on the mounting part 21. The suction end of the air pump 10 is connected to a suction hole of the mounting part 21 through a conduit. The suction hole penetrates the upper and lower end faces of the mounting part 21, so that the gas around the massage head 43 can be drawn away by the air pump 10, so that the outer shell 1 can be adhered to the skin after a negative pressure is formed inside the outer shell 1. The air outlet end of the air pump 10 is connected to a vent hole of the outer shell 1 through a conduit. The vent hole penetrates the arc-shaped cover 22 and the silicone sleeve 101, so that the air drawn by the air pump 10 can be discharged from the vent hole.

[0047] To control the air pump 10, the button assembly 8 also includes a start / stop button located between the acceleration and deceleration buttons. Pressing and holding this start / stop button activates the air pump 10 and keeps it pumping air continuously, while releasing it stops the air pump 10 from pumping air. Additionally, this start / stop button can control the rotation direction of the rotary drive motor 3. For example, a short press of the start / stop button causes the output shaft of the rotary drive motor 3 to rotate clockwise, while a second press causes the output shaft to rotate counterclockwise.

[0048] The following describes the specific working principle of this utility model in order to help you understand it:

[0049] First, after assembling all the components of the massager, when adjusting the height of the massage head 43, the lower massage frame 42 is manually rotated, which drives the insertion rod 44 to move accordingly in the track groove 45. When the insertion rod 44 is locked in the upper position positioning port 46, the massage head 43 is adjusted upward, and when the insertion rod 44 is locked in the lower position positioning port 47, the massage head 43 is adjusted downward.

[0050] Next, press and hold the accelerator button to power on;

[0051] Next, the outer shell 1 is placed on the skin to be massaged, and the air pump 10 is driven to work by the start / stop button, so that the outer shell 1 is finally attached to the appropriate position.

[0052] Next, adjust the speed of the rotary drive motor 3 by pressing the acceleration or deceleration button a few times to adjust it to the desired speed. Then, the massage head 43 rotates and massages the skin. In addition, the rotation direction of the output shaft of the rotary drive motor 3 can be adjusted by pressing the start / stop button a few times to meet different massage needs.

[0053] This utility model is not limited to the above-described embodiments. If any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
