[0046] like Figure 6 In one embodiment, three limit slots 41 are provided, and three limit blocks 51 are also provided. By cooperating and connecting the plurality of limit blocks 51 with the limit slots 41, the light-transmitting member 50 can be better cooperating and connected with the light-shielding member 40, the connection is reliable, and the light-transmitting member 50 can be prevented from moving in the horizontal direction relative to the light-shielding member 40.

[0047] In one embodiment of the utility model, the phototherapy head body 10 includes a boss structure 11, a light-transmitting hole 111 is opened on the boss structure 11, the light source assembly 20 is located in the light-transmitting hole 111, the light source assembly 20 is suitable for emitting the therapeutic light through the light-transmitting hole 111, the convex lens 30 is installed on the boss structure 11 and covers the light-transmitting hole 111, and the shading member 40 is sleeved outside the boss structure 11.

[0048] It is worth noting that the boss structure 11 is used to install the light source assembly 20 and the convex lens 30. The light source assembly 20 is installed in the light-transmitting hole 111 of the boss structure 11; the convex lens 30 covers the light-transmitting hole 111, so that the therapeutic light emitted from the light-transmitting hole 111 can be focused; at the same time, the shading member 40 is mounted on the outside of the boss structure 11 to cover the convex lens 30 and the light source assembly 20 in the boss structure 11, so as to facilitate shielding the therapeutic light around the convex lens 30 and the light source assembly 20.

[0049] The convex lens 30 fits the surface of the phototherapy head body 10 to avoid a gap between the convex lens 30 and the phototherapy head body 10, so that the convex lens 30 can focus the therapeutic light emitted from the light-transmitting hole 111; the convex lens 30 can be bonded to the boss structure 11, or the convex lens 30 can be clamped by a limiting structure. The specific installation method can be selected according to actual needs. Provide an embodiment, such as Figure 5 The surface of the boss structure 11 is provided with a plurality of limiting protrusions 112, and the plurality of limiting protrusions 112 enclose a mounting position 113. The convex lens 30 is mounted in the mounting position 113, and its side wall is supported against the inner wall of the limiting protrusion 112, which is convenient for installation and has a stable connection.

[0050] In one embodiment of the utility model, the phototherapy head 100 also includes a sensor 60, which is installed on the surface of the boss structure 11, and the sensor 60 is located between the convex lens 30 and the boss structure 11. The sensor 60 is used to detect whether the light-transmitting member 50 is in contact with the user's skin.

[0052] An embodiment is provided, in which the sensor 60 is set as a pressure sensor. A through hole is provided in the middle of the pressure sensor, corresponding to the light-transmitting hole 111, so as to facilitate the emission of light from the light source assembly 20. The pressure sensor is placed on the surface of the boss structure 11, and is supported on the pressure sensor by a convex lens 30 for installation, so as to facilitate receiving pressure signals. The pressure sensor can determine whether the light-transmitting member 50 fits the user's skin by detecting pressure. When the light-transmitting member 50 and the light-shielding member 40 are integrally formed, the light-shielding member 40 and the boss structure 11 are connected by an adhesive layer structure 114, and the light-transmitting member 50 contacts the user's skin.

[0053] In another embodiment, the sensor 60 is set as a distance sensor. In this case, the shading member 40 is relatively fixed to the phototherapy head body 10 so that the shading member 40 cannot move. By detecting the distance between the skin and the distance sensor, it is determined whether the light-transmitting member 50 is in contact with the user's skin.
