Specifically, the top of each of the pins  321  is provided with a contact terminal  322 , and a first elastic member  323  is accommodated in each contact terminal  322 . Preferably, the first elastic member  323  is a spring. In this way, under the pressure of the spring, the contact terminal  322  can always keep stable electric connection with the first PCB  120 . The second PCB  320  is electrically connected to the first PCB  120  via the pins  321 , and can also heat the eyes. 
         [0034]    In this way, through the above connection structure, gas path connection and circuit connection between the blinder  300  and the helmet are achieved. A detachable connection structure for the blinder  300  and the helmet includes two groups of reciprocal lock holes and lock components. Referring to  FIGS. 2 ,  8 , and  9 , the two lock holes  330  are respectively disposed on two end faces of the eye housing  310 , and the two lock components  500  are respectively disposed on an end face of the front shell  100 . The front shell  100  is provided with two mounting grooves  130 , and each mounting groove  130  accommodates a limiting post  140 . Each lock component  500  comprises a lock catch  510  accommodated in one of the mounting grooves  130  and a second elastic member  520  disposed behind the lock catch  510  for pressing against the lock catch  510 . Specifically, the second elastic member  520  is a spring. Each lock catch  510  is provided with a strip-shaped groove  511 , the limiting post  140  is inserted in the strip-shaped groove  511 , and the lock catch  510  is movable forward and backward in the limitation range of the limiting post  140 . A front portion of the lock catch  510  is provided with an inserting part  512 , and the inserting part  512  extends from the mounting groove  130  and is inserted in the lock hole  330 . The bottom of the lock catch  510  is provided with a toggle part  513 , the bottom of the mounting groove  130  is provided with a gap  150 , and the toggle part  513  is movable in the gap  150 . 
         [0035]    In this embodiment, in order to ensure the reliability of the connection between the blinder  300  and front shell  100 , the front shell  100  is further provided with a location hole  160 , and the eye housing  310  is provided with a location column  340 , correspondingly. The blinder  300  and the front shell  100  can be positioned and connected together quickly by inserting the location column  340  into the location hole  160 . 
         [0036]    Furthermore, referring to  FIG. 10 , in this embodiment, a blood oxygen detecting device  600  is accommodated inside the blinder  300 , and the blood oxygen detecting device  600  is electrically connected to the controller. Understandably, the blood oxygen detecting device  600  may also be disposed inside the front shell  100 . When the blinder  300  is mounted to massage, the blood oxygen detecting device  600  can cling to the user&#39;s forehead, detect the user&#39;s blood oxygen concentration data, and display the data by the controller in real time. It is convenient for users to know the blood oxygen situation and thereby adjust the head massager properly. For some users suffering from disease, real-timely detected blood oxygen data can play a role in warning and guidance. 
         [0037]    Referring to  FIG. 11  and  FIG. 14 , the blood oxygen detecting device  600  comprises a flexible sleeve  610 , a third elastic member  620  disposed in the flexible sleeve  610 , and two blood oxygen sensors  630  disposed on the third elastic member  620 . In this way, the whole blood oxygen detecting device  600  can stretch and shrink freely. When the head massager is used by different persons respectively, the blood oxygen detecting device  600  stretches or shrinks according to different head sizes, which ensures that the blood oxygen sensor  630  always clings to the human body skin and further ensures the accuracy of the test. In this embodiment, in order to ensure good flexibility of the flexible sleeve  610 , the flexible sleeve  610  is made of flexible glue and uses wavy design, so the flexible sleeve  610  itself has extensibility and can be prevent from deviating to some extent during stretch and shrink. In this embodiment, the blood oxygen detecting device  600  is fixed on an inner side of the eye housing  310  through the flexible sleeve  610 . Specifically, the bottom edge of the flexible sleeve  610  is provided with a flange  611 , and the inner side of the eye housing  310  is correspondingly provided with a clamping slot (not shown) for clamping the flange  611 , so that the flexible sleeve  610  is fixed, and the blood oxygen detecting device  600  is further fixed. 
         [0038]    An upper open  150  of the flexible sleeve  610  is provided with a connection block  612 , the connection block  612  and the open  150  of the flexible sleeve  610  from a cavity, and the blood oxygen sensor  630  is accommodated in the cavity and is fixed by an upper support  640  and a lower support  650 . The third elastic member  620  is disposed in the space below the connection block  612 . 
         [0039]    The upper support  640  comprises two pressing pieces  641  and two hook  642  extending downward from two opposite edges of each pressing piece  641  respectively. Each pressing piece  641  is provided with an aperture  6411 . Each pressing piece  641  is disposed on one of the blood oxygen sensors  630 , and a sensing surface of the blood oxygen sensor  630  is exposed from the aperture  6411 . The connection block  612  is provided through slots  6121  corresponding to the hooks  642  of the pressing pieces  641 , and the lower support  650  is provided with latching slots  651  corresponding to the through slots  6121 . In this way, the hooks  642  of the upper support  640  pass through the through slots  6121  and the latching slots  651  and hook the edges of the latching slots  651 . Thus, the upper support  640  and the lower support  650  achieve a clamp connection, and the blood oxygen sensors  630  and the connection block  612  are clamped between the upper support  640  and the lower support  650 . 
         [0040]    Furthermore, in order to ensure that the hooks  642  can be conveniently and quickly inserted into the latching slots  651 , the edge of each latching slot  651  is provided with an inclined edge  652 . Thus, by the guide function of inclined surfaces, the hooks  642  can quickly enter the slots  651  and hook the bottoms of the inclined edges  652 . 
         [0041]    In this embodiment, the bottom of the lower support  650  is provided with a fixing column  653 , and the upper end of the third elastic member  620  sleeves around the fixing column  653 . In this way, the third elastic member  620  is limited by the fixing column  653 , which can prevent the elastic member  620  from inclining during stretch and shrink. Preferably, the third elastic member  620  is also a spring. 
         [0042]    In this embodiment, two above-mentioned blood oxygen sensors  630  are disposed in one flexible sleeve  610 . Of course, one, three, or more blood oxygen sensor  630  may be disposed in the flexible sleeve  610 . It should be noted that the blood oxygen sensor  630  may be commercially available and may be any kind. For example, a photoelectric blood oxygen sensor using the photoelectric principle for collection may be used. When the head massager is used, the blood oxygen detecting device  600  clings to eyelids to test the blood oxygen condition, and shows test results by the controller. In this way, users can grasp the blood oxygen situation in real time and adjust the massage. 
         [0043]    In this embodiment, when the head massager is used, if the user wants to remove the blinder  300 , he/she can toggle the two lock catches  510  back respectively or simultaneously, so that the inserting part  512  on the front portion of each lock catch  510  exits from the lock hole  330  and the pins  321  of the second PCB  320  on the eye housing  310  are separated from the first PCB  120 . A magnetic valve disposed in the front shell  100  for controlling air communication of the air bag receives a single and then keeps a closed state. In this way, the eye massage function is stopped but doesn&#39;t affect the head massage function. Finally, the pipe joint  311  is pulled out and is separated from the air tap  110 , that is, the blinder  300  is removed completely. When the blinder  300  needs to be mounted, the location columns  340  of the eye housing  310  are aligned with the location holes  160  of the front shell  100  and pushed forward. At the moment, under the action of the springs, the two lock catches  510  slide outward. When the location columns  340  are completely pushed into the location holes  160 , the lock catches  510  move forward under the push action of the springs and drive the inserting parts  512  thereof slide into the location holes  330  completely. If there is no external force, due to the pressure of the springs, the lock catches  510  themselves cannot slide. In this way, the blinder  300  is fixed on the front shell  100 ; at this time, the pins  321  on the blinder  300  are electrically connected to the first PCB  120 , and the pipe joint  311  communicates with the air tap  110 . Both the massage function and the heat function of the blinder  300  are enabled, and the blood oxygen detecting device  600  is started, so that the head massage, the eye massage, and the blood oxygen detection can be performed simultaneously. 
         [0044]    In conclusion, the multifunctional head massager of the present invention can simultaneously massage the head and the eyes and detect the blood oxygen, or only massage the head after the blinder is removed. This selectable working mode is more convenient for use. 
         [0045]    What described above are only preferred embodiments of the present disclosure but are not intended to limit the scope of the present disclosure, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
