The microcontroller 30 is configured to output the first electrical signal to the output switching circuit 20, and the output switching circuit 20 switches the output paths between the plurality of massage heads 10 after receiving the first electrical signal.
The neck massager comprises an elastic support and a plurality of massage heads 10 which are arranged on the inner concave surface of the elastic support at intervals, and is used for massaging the neck of a human body. The number of the massage heads 10 is more than three, a control circuit is arranged in each massage head 10, the control circuit of each massage head 10 is electrically connected with an output switching circuit 20, the operation of each massage head 10 is controlled through the output switching circuit 20, and the output switching circuit 20 is controlled through a microcontroller 30. The control circuits of the plurality of massage heads 10 may be connected in series or in parallel, and the circuit connection state is switched by the output switching circuit 20, so as to control the operation mode of the massage heads 10, thereby diversifying the operation modes of the massage heads 10, such as the operation of the plurality of massage heads 10 in series, or the operation of a part of the massage heads 10 in series, or the operation of the plurality of massage heads 10 in parallel, or the operation of a part of the massage heads 10 in parallel. Since the positions of the massage heads 10 on the neck massage apparatus are different, the massage areas and effects are also different when the electric connection modes between the massage heads 10 are switched. Different operation modes of the massage head 10 can be set as different operation modes of the neck massage device, and users can switch freely to experience different massage effects.
The output passages in the present embodiment include a first output passage formed between any two of the massage heads 10 and a second output passage formed in parallel between the plurality of massage heads 10. The first output passage is formed by connecting any two massage heads 10 in series, and the second output passage is formed by connecting a plurality of massage heads 10 in parallel. When the first output path is output, the neck massager is operated by only two massage heads 10 connected in series, and a user can select any two positions of the massage heads 10 to massage, so that the massage requirements of the user can be accurately identified and responded. When the second output path is output, the massage heads 10 are operated in parallel, and the user can select the massage heads 10 at a plurality of positions to massage simultaneously. Because the multiple massage heads 10 are arranged in the embodiment, and the positions of the multiple massage heads 10 on the neck massager are different, a user can select any two massage heads 10 to work for massaging, and can select the multiple massage heads 10 to work for massaging at the same time, so that the massaging modes of the neck massager are enriched.
Optionally, in another embodiment, the second output path is a parallel output path formed by taking any one of the massage heads 10 as a common output end and taking the other massage heads 10 as output ends, and the second output path takes any one of the massage heads 10 as a common output end and forms a plurality of parallel output paths with the other massage heads 10, so that the massage heads 10 massage simultaneously, and the simultaneous massage area is enlarged.
The first electrical signal in the present embodiment includes a first strobe signal for controlling the output switching circuit 20 to switch between any two of the massage heads 10 to a first output path, and a second strobe signal for controlling the output switching circuit 20 to switch between the plurality of massage heads 10 to a second output path. The microcontroller 30 controls and switches the operation modes of the massage heads 10 by outputting a first electric signal to the output switching circuit 20, wherein the first electric signal comprises a first gating signal for controlling any two massage heads 10 to operate in series, and also comprises a second gating signal for controlling a plurality of massage heads 10 to operate in parallel, and the output switching circuit 20 receives the electric signal and switches the electric connection modes of the massage heads 10 according to different electric signals output by the microcontroller 30 operated by a user, so that different massage modes are operated.
The microcontroller 30 in this embodiment alternately outputs the first strobe signal and the second strobe signal, that is, allows the plurality of massage heads 10 to be continuously switched between the serial connection and the parallel connection states, and alternately massages at different positions of the neck of the human body, so as to form a new massage mode and increase the massage modes.
Referring to fig. 2 and 3, fig. 2 is a schematic diagram of a control system of a multi-massage head and neck massage apparatus according to a second embodiment of the present invention, and fig. 3 is a circuit diagram of a wearing detection circuit, wherein the neck massage apparatus of the present embodiment includes a wearing detection circuit 40 for detecting an energizing state between any two massage heads 10 in addition to the plurality of massage heads 10, the output switching circuit 20 and the microcontroller 30. The neck massager in this embodiment is capable of realizing a massage function by contacting the electrodes in the massage heads 10 with a human body to form micro-current pulses, when the elastic support of the neck massager is deformed, the human neck and the massage heads 10 may be separated, at this time, the massage mode of the neck massager may be switched to invalid operation by the output switching circuit 20, the wearing detection circuit 40 is used for detecting the electrified state between the massage heads 10, that is, whether the first electric signal sent by the microcontroller 30 is valid or not is monitored at any time, and the user can conveniently adjust the massage mode according to the detection result of the wearing detection circuit 40.
The microcontroller 30 in this embodiment further includes a wear detection signal input connected to the wear detection circuit 40; the wear detection circuit 40 outputs a second electric signal to the wear detection signal input terminal, and controls the microcontroller 30 to switch the output state of the first electric signal. After detecting the information of the current state between the massage heads 10, the wearing detection circuit 40 inputs the information to the wearing detection signal input terminal, thereby controlling the electric connection state between the massage heads 10, that is, switching the massage mode of the neck massage apparatus.
The present embodiment will be described below by way of a specific scenario.
Taking the neck massager as an example, three massage heads 10 are provided, when the user wears the neck massager, the three massage heads 10 correspond to the left and right sides and the middle side of the neck, respectively, so as to cover the entire neck of the user. During use, the user may move the neck to form a side head, a low head, etc., and the massage head 10 may be separated from the skin of the human body. The wear detection circuit 40 is used for detecting contact and fitting conditions of three massage heads 10 and human skin, when one massage head 10 is not in contact with the human body, the wear detection circuit 40 outputs a second electric signal to the microcontroller 30, and after the microcontroller 30 receives the second electric signal, the state of the first gating signal or the second gating signal is enabled or disabled, so that the massage head 10 does not output, and an output passage is formed between the other two massage heads 10 for massaging. For example, when the user is on the side, the massage head 10 on one side and the middle of the side is conducted, and the massage head 10 on the other side is not output; when the user lowers the head, the massage heads 10 on the two sides are conducted, and the middle massage head 10 does not output. Thus, not only allows the user to adjust the wearing posture when using the product and reduces the use restriction of the product, but also avoids the tingling sensation caused by the bad contact of the massage head 10.
The first electric signal in this embodiment further includes a massage current selection signal that controls the output switching circuit 20 to output a radio frequency current generation circuit or a low frequency current generation circuit. The radio frequency current generating circuit plays a role in radio frequency heating and hot compress, the low frequency current generating circuit plays a role in muscle electric stimulation, and the first electric signal can control the current output state besides controlling the conduction state of the massage head 10, so that the massage modes are more diversified.

The arrangement enables the radio frequency current generating circuit and the low frequency current generating circuit to be communicated to form a plurality of current groups, and the massage heads 10 of the current groups are all arranged in series. The output switching circuit 20 controls the connection and switching of the plurality of current groups, that is, switches the connection state between the massage heads 10, and the microcontroller 30 sends out an electric signal according to the neck massager working mode selected by the user, and the output switching circuit 20 switches to the corresponding current group after receiving the electric signal, so that the corresponding massage head 10 starts to operate. When the user switches the massage mode, the state of electrical connection between the plurality of massage heads 10 is switched by the output switching circuit 20, thereby switching to another current group. Because the output switching circuit 20 includes a plurality of bi-directional optical couplers, which are respectively connected to one port of the output switching circuit 20, the output switching circuit 20 is respectively connected to two output ends of the radio frequency current generating circuit and the low frequency current generating circuit, so that the output switching circuit 20 can be switched to operate the radio frequency current generating circuit or the low frequency current generating circuit at will, and each current group at least includes one path of the low frequency current generating circuit and one path of the radio frequency current generating circuit.
The neck massage apparatus includes three massage heads, and the low-frequency current generating circuit and the radio-frequency current generating circuit are both provided with two paths of generating circuits, and the output switching circuit 20 includes 8 bi-directional conductive optocouplers.
When a user wears the neck massager, each low-frequency current generating circuit and each radio-frequency current generating circuit comprise two output ends, the output ends of each low-frequency current generating circuit and each radio-frequency current generating circuit are respectively connected with one port of the bidirectional conduction optocoupler, and eight output ends are formed in total by the two low-frequency current generating circuits and the two radio-frequency current generating circuits, and the output ends correspond to the number of the bidirectional conduction optocouplers. The low-frequency current generating circuit and the radio-frequency current generating circuit are used as a group of current groups, and the other ports connected with the output ends of the current groups are connected with each other and are respectively connected with different massage heads. The bidirectional conduction optocoupler is used for inputting a massage current selection signal to switch the massage current group, namely switching the massage mode of the neck massager. The selection and the switching of the massage current of the neck massage instrument are realized through the bidirectional conduction optocoupler, so that the circuit is simple to connect and is easier to operate.
Further, the output switching circuit 20 includes four first gate circuits, referring to fig. 4, fig. 4 is a circuit diagram of the output switching circuit, and the four first gate circuits include bidirectional optocouplers for selecting the outputs of the B output terminal and the D output terminal in fig. 4. In fig. 4, the output end a and the output end D are connected together to the first massage head, the output end B and the output end D are connected together to the second massage head, and the output end B and the output end C are connected together to the third massage head, so that a conductive selection circuit for the massage head is provided, and the operation of the massage head is controlled by connecting any two output ends.
The output switching circuit 20 in this embodiment further includes a driving circuit of the first gating circuit, where an input end of the driving circuit is connected to a first signal output end of the microcontroller 30, and an output end of the driving circuit is connected to an input end of the first gating signal.
