[0033] The following will clearly and completely describe the technical solutions in this embodiment with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] It should be noted that in the description of the present invention, all directional indications (such as up, down, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0035] In addition, the terms "first," "second," and so on, used in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being described. In the description of this utility model, "several" means at least two, such as two or three, unless otherwise specifically defined.

[0036] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that technical personnel in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0037] like Figure 1-8 As shown, the technical solution of the present invention is: a multi-head massager, including a shell 1, a transmission assembly and a massage head assembly. The shell 1 includes a detachable upper shell 11 and a lower shell 12, which are convenient for installation of various parts in the shell 1 and easy disassembly and maintenance. Six openings 13 are opened at the bottom of the lower shell 12, and hand-held parts 14 are symmetrically provided on both sides of the shell 1, which are convenient for smooth and steady holding of the massager and for people to apply force evenly.

[0038] A drive motor 3 is provided in the housing 1 , and the drive motor 3 is supported and fixed to the support column on the upper shell 11 . The drive motor 3 is suspended as a whole and does not make large-area contact with the inner wall of the housing 1 , which is beneficial to heat dissipation of the drive motor 3 .

[0039] The massage head assembly includes a connecting bracket 6, which includes a mounting end 61 and two massage ends 62 with massage heads 2;

[0040] The transmission assembly includes an eccentric wheel 5 and a movable bracket 4. The movable bracket 4 includes a transmission rod 41 and three connecting shafts 42 extending outward from the housing 1. Each connecting shaft 42 is correspondingly provided with a connecting bracket 6. Each connecting shaft 42 is pluggably connected to a mounting end 61 of a connecting bracket 6.

[0041] The transmission rod 41 and the connecting shaft 42 are integrally formed to reduce the number of connecting parts and the probability of damage, and optimize costs. The three connecting shafts 42 are evenly distributed on the transmission rod 41, so that the overall center of gravity is in the middle of the transmission rod 41. The middle of the transmission rod 41 is connected to the output shaft of the drive motor 3 through the eccentric wheel 5, thereby controlling the vibration amplitude of the connecting brackets 6 at both ends of the transmission rod 41 to be equal when the transmission rod 41 is driven by the motor, ensuring equal massage strength and enhancing the massage sensation.

[0042] The eccentric wheel 5 includes a wheel portion 51 fixedly connected to the output shaft of the drive motor 3 and an eccentric shaft portion 52 eccentrically arranged relative to the output shaft of the drive motor 3. The eccentric shaft portion 52 is engaged with the middle portion of the transmission rod 41 in the movable bracket 4, so that when the output shaft of the drive motor 3 rotates, the movable bracket 4 is controlled to reciprocate along the circular trajectory of the eccentric shaft portion 52 as a whole, driving the massage head 2 fixed relative to the movable bracket 4 to vibrate, thereby playing a massage role when the massage head 2 is attached to the human body.

[0043] Furthermore, a counterweight 10 in a circular ring structure is provided at the fixed connection point in the middle of the transmission rod 41, which is used to increase the weight of each movable bracket 4, increase the inertia of the movable bracket 4, reduce the acceleration generated by the drive motor 3, make the overall movement smoother, reduce the load of the movable bracket 4, and enhance the service life. The eccentric shaft 52 is connected to the inner center of the counterweight 10 by providing a number of protrusions on the outer periphery as anti-slip patterns, thereby realizing the connection between the eccentric shaft 52 and the movable bracket 4.

[0044] The connecting shaft 42 is provided with a countersunk hole for the mounting end 61 to be inserted and engaged. The countersunk hole in the connecting shaft 42 and the mounting end 61 are respectively provided with a first flat surface 43 and a second flat surface 63 for engagement, so as to prevent the mounting end 61 and the connecting shaft 42 from rotating relative to each other after being plugged in and engaged, thereby preventing the connection between the connecting bracket 6 and the movable bracket 4 from becoming loose and causing the movable bracket 4 to detach.

[0045] Furthermore, the mounting end 61 and the connecting shaft 42 are clamped by setting a tightening piece 7. The tightening piece 7 is set between the mounting end 61 and the connecting shaft 42 to clamp them to prevent them from loosening and causing the movable bracket 4 to fall off, thereby causing the massage head 2 to fall off on the massager.

[0046] A groove is provided on the outer surface of the middle part of the mounting end 61 for sleeve-mounting the expansion member 7. The two end faces of the groove are in contact with and limit the expansion member 7 to prevent the expansion member 7 from falling off the mounting end 61. Therefore, after the top end of the mounting end 61 is aligned and inserted into the countersunk hole, the expansion member 7 is squeezed into the countersunk hole to complete the clamping. In this way, the installation operation is easier to clamp the expansion member 7, and the expansion member 7 is arranged outside the mounting end 61 instead of in the countersunk hole of the connecting shaft 42, so that the expansion member 7 is easier to be discovered when it is damaged, and the expansion member 7 can be replaced more promptly before the clamping operation is performed.

[0047] The connecting shaft 42 is covered with a soft rubber sleeve 8, which is fixed to the housing 1 through a mounting plate 81. When the connecting shaft 42 is vibrated by the driving motor 3, the soft rubber sleeve 8 is driven to deform and expand, thereby effectively reducing the noise generated by the vibration and transmitted to the outside world.

[0048] The driving motor 3 is a dual-axis motor, and there are two groups of transmission components, which are symmetrically arranged on both sides of the driving motor 3 and connected to the two output shafts. A dual-axis motor is used as the driving motor 3, and transmission components are arranged on both sides thereof, so that the overall body is symmetrical and the weight is evenly balanced. After the whole body is placed on the human body, there is no situation where one side is heavy and the other side is light, which makes the overall user feel better.

[0049] A hot compress 9 is fixedly provided at the bottom of the lower shell 12. The hot compress 9 is correspondingly arranged at the bottom of the drive motor 3. It can be a heating pad, which uses a built-in electric heating element to generate warmth and uses the heat generated when the drive motor 3 is working, so that heat is transferred to the massage area during massage, which can help relax muscles, improve local blood circulation, and help relieve muscle fatigue.

[0050] Specifically, by setting a connecting bracket 6, a mounting end 61 is set at one end of the connecting bracket 6 and can be plugged and unplugged with the connecting shaft 42, the connecting bracket 6 can be installed on the connecting shaft 42 extending out of the shell 1, and multiple massage ends 62 are set at the other end of the connecting bracket 6 for installing the massage head 2, so that the connecting shaft 2 extending from the opening of one shell 1 can be connected to control multiple massage heads 2, making full use of the space under the shell 1, increasing the upper limit of the number of massage heads 2, and enhancing the efficiency of massage. When replacing the massage head 2, the entire connecting bracket 6 with the massage head 2 is directly replaced. When replacing, there is no need to apply force on the massage head 2 when plugging and unplugging the connecting bracket 6, avoiding damage to the massage head 2, and replacing the massage head 2 is easier and simpler.

[0051] To sum up, in this embodiment, two movable brackets 4 are provided, and each movable bracket 4 extends three connecting shafts 42 outside the shell 1 through the opening 13. Each connecting shaft 42 is fixed with a connecting bracket 4 by a plug-in. Each connecting bracket 4 includes two massage ends 62 with massage heads 2. Thus, this massager can control twelve massage heads 2 to perform massage. After the drive motor 3 is driven, the eccentric wheel 5 drives the movable bracket and the connecting bracket 6 to perform a circular reciprocating motion around the output shaft of the drive motor 3, thereby realizing the massage action of each massage head 2.
