The phototherapy instrument is a therapeutic instrument using light as energy source, and mainly uses the phototherapy head to emit light to treat the treatment area. Skin diseases such as psoriasis, vitiligo, cutaneous lymphoma, atopic dermatitis, etc. are usually treated by phototherapy.

However, the light-emitting switch of the existing phototherapy apparatus may be triggered by mistake, and the light-emitting operation is still performed under the condition that the phototherapy head is not close to the treatment area along the light-emitting direction, so that the invalidation of the light-emitting operation is caused, and even the non-treatment area of the human body is burned.

In view of the above problems, the present utility model proposes a phototherapy head 100.

Referring to fig. 1 to 5, in one embodiment of the present utility model, the phototherapy head 100 includes a housing assembly 10 and a detection sensor 40, a light member 30 is disposed in the housing assembly 10, and a light outlet 131 is formed in the housing assembly 10 along a light outlet direction of the light member 30; the detection sensor 40 is disposed along the light emitting direction of the light emitting hole 131, and the detection sensor 40 is used for detecting the close condition of the treatment area and is electrically connected with the control unit of the light member 30.

Specifically, the housing assembly 10 is provided with a cavity for mounting the working device. The housing assembly 10 may include a first housing 11 and a second housing 13, the first housing 11 and the second housing 13 enclosing to form a cavity in which the working devices of the phototherapy head 100, such as the lamp 30, the heat sink 20, and the circuit board lamp are disposed. The first housing 11 and the second housing 13 can be detachably connected. The number of housings of the housing assembly 10 is not fixed.

The lamp member 30 is a device for light-emitting treatment such as red, blue, yellow lamps for improving the condition of the skin, increasing the elasticity of the skin, and ultraviolet lamps for treating vitiligo and psoriasis.

The detection sensor 40 is used to detect the close proximity of the phototherapy head 100 to a treatment area, which is an area for light-emitting treatment. For example, the detection sensor 40 is a contact sensor such as a piezoelectric sensor, and when the phototherapy head 100 is sufficiently contacted with the treatment area and a contact pressure is generated, the contact sensor receives a pressure signal and recognizes that the phototherapy head is attached to the treatment area. Alternatively, the detection sensor 40 is a non-contact sensor, such as a capacitive sensor or an infrared sensor, and when the distance between the phototherapy head 100 and the treatment area is smaller than the threshold value, the phototherapy head is considered to be attached to the treatment area.

In the technical scheme of the utility model, firstly, the lamp 30 in the shell assembly 10 emits light through the light emitting hole 131, and the detection sensor 40 is arranged along the light emitting direction of the light emitting hole 131; next, in order to perform the light-emitting treatment on the treatment area of the human body, the entire phototherapy apparatus is attached to the treatment area along the light-emitting direction of the light-emitting hole 131, and at the same time, the detection sensor 40 is attached to the treatment area; finally, when the detection sensor 40 senses that the phototherapy head is fully attached to the treatment area, an electrical signal for starting the lamp is sent to the control unit of the lamp 30, the lamp 30 is triggered to emit electricity and light, and the light-emitting treatment of the treatment area is realized through the light-emitting hole 131.

Compared with the prior art that the phototherapy apparatus performs the light emitting operation through the phototherapy head 100 due to false triggering under the condition that the phototherapy apparatus is not close to the treatment area, the phototherapy apparatus of the present utility model performs the light emitting operation only under the condition that the phototherapy head 100 is close to the treatment area along the light emitting direction even though the phototherapy head 100 is triggered by false.

Therefore, the phototherapy head 100 of the present utility model avoids abnormal light emission phenomenon caused by false triggering of the light emitting switch.

Referring to fig. 1 to 5, in an embodiment of the present utility model, the phototherapy head 100 further includes a light-emitting mask 60, the light-emitting mask 60 covers a hole wall connected to the light-emitting hole 131, and the detection sensor 40 is disposed on an inner side of the light-emitting mask 60 or an outer side of the light-emitting mask 60.

Specifically, the light emitting cover 60 covers the light emitting hole 131 to prevent external dust from entering the cavity of the housing assembly 10, thereby contaminating the lamp 30. In addition, the end surface of the light emitting cover 60 for adhering to the treatment area is used as a treatment surface, and the treatment surface can be in a cambered surface shape so as to realize full adhering to the skin of a human body.

It should be noted that, the detection sensor 40 is disposed inside the light emitting mask 60 facing the light emitting hole, which does not mean that the detection sensor is disposed only inside the mask body of the light emitting mask 60, but may be disposed along the side direction of the light emitting mask 60, for example, the detection sensor 40 may be disposed at the opening edge of the light emitting hole 131.

Compared with a parallel-mounted circular ring surface sensor, the embodiment effectively increases the surface area of the mounting of the detection sensor 40 on the basis of ensuring that the lamp 30 emits light normally through the detection sensor 40, and then improves the detection sensitivity of the detection sensor 40.

For example, in the case of ensuring normal light emission from the light emitting hole 131, the detection sensor 40 is mounted on the opening edge of the light emitting hole 131 in a forward tapered shape or an inverse tapered shape.

Optionally, in an embodiment of the installation and setting of the detection sensor 40, the housing assembly 10 is provided with a ring groove 133 at an outer edge of the opening of the light exit hole 131, a groove wall of the ring groove 133 is gradually expanded along the light exit direction, the detection sensor 40 is configured as a ring belt, and the detection sensor 40 is attached to the ring groove 133. The present embodiment realizes that the detection sensor 40 is obliquely mounted through the annular groove 133 provided on the wall of the light exit hole 131.

In this embodiment, the sensing area of the detection sensor is effectively increased and the detection sensor is configured in a strip shape under the condition that the light emitting member 30 is ensured to emit light normally through the light emitting hole 131 without being blocked by the detection sensor. The number of the detection sensors is multiple, the detection sensors are inclined and circumferentially arranged at intervals, and then the through holes for the light emergent holes 131 to normally emit light are formed in a surrounding mode.

Optionally, to effectively improve the detection accuracy of the contact sensor, a plurality of contact sensors are circumferentially spaced apart from each other on the bonding surface of the light-emitting mask 60.
