The present invention relates to an ultrasonic treatment device, and more particularly, to an ultrasonic treatment device used for skin care.

It relates to a device for cleaning structures present in water.

As interest in appearance increases, the skin beauty device market is growing. In particular, the non-invasive method is in the spotlight due to its low safety and high patient rejection, and among the non-invasive methods, skin beauty devices using High Intensity Focused Ultrasound (HIFU) are being developed. Beauty devices using high-intensity focused ultrasound focus high-intensity ultrasound on a certain point in the skin of the human body, and the focused area causes thermal damage. This thermal damage causes synthesis of new collagen fibers in the skin, and through this, skin elasticity can be improved or wrinkles can be alleviated. Beauty devices using high-intensity focused ultrasound are known to be safe for the skin and have a high skin improvement effect.

On the other hand, the skin layer is composed of the epidermis layer, the dermis layer, the subcutaneous fat layer, and the fascial layer (SMAS layer) sequentially from the outer surface. In order to focus and irradiate the ultrasonic waves on these various skin layers, the ultrasonic focusing point and the output value of the ultrasonic waves must be simultaneously changed. In addition, when the focused ultrasound is irradiated to the fascial layer (SMAS layer), the effect of skin improvement is most excellent. Since the thickness of the skin layer is different for each person and for each treatment area, the location of the ultrasound focusing point and ultrasound in consideration of the thickness of the skin layer The effect of skin improvement can be enhanced only when the output value is selected.

However, conventional beauty devices using high-intensity focused ultrasound do not change the position of the focal point of ultrasound or the output value of the focused ultrasound, or the user has to replace the cartridge that outputs ultrasound to change the output value of the focused ultrasound. There was a cumbersome problem.

Therefore, the present invention was invented to solve the above problems, and an object of the present invention is to provide an ultrasonic treatment device capable of simultaneously changing the position of an ultrasonic focusing point and the output value of focused ultrasonic waves without replacing a cartridge that outputs ultrasonic waves.

The knob and the lead screw may be coupled to each other by thread engagement, and the knob and the thread of the lead screw may come into close contact with each other by elasticity.

The ultrasonic irradiation movable body may be detachably coupled to the lead screw.

The ultrasonic irradiation movable body may be installed in a housing having a guide unit for guiding a moving direction of the ultrasonic irradiation movable body.

The ultrasonic irradiation movable body is disposed in an enclosed space within the cartridge housing, and includes an ultrasonic output unit for outputting ultrasonic waves; and a coupling portion exposed to the outside of the closed space and coupled to the lead screw.

The ultrasonic irradiation movable body may output ultrasonic waves having different values according to rotation of the knob.

The ultrasonic waves having different values may be output by selectively electrically connecting any one of the plurality of contact parts provided in the main body part and one connector rotating together with the nod part.

The knob 120 may be rotatably coupled to the body portion 100 . In one aspect, the knob 120 may be rotatably coupled to the body housing 110 . Referring to FIG. 3 , the knob 120 is mounted on the top of the body housing 110 and the body cover 111 is coupled with the body housing 110 with the knob 120 interposed therebetween so that the knob 120 rotates. Possibly it can be coupled to the body housing 111.

The lead screw 130 may be coupled to the knob 120 to be movable along a rotational axis of the knob 120 by rotation of the knob 120 .

In one aspect, knob 120 and lead screw 130 may be threaded. Referring to FIG. 5 , screw threads corresponding to each other may be provided on an inner circumferential surface of the knob 120 and an outer circumferential surface of the lead screw 130 . When the knob 120 is rotated, the lead screw 130 may move along the axis of rotation of the knob 120 . For example, when the knob 120 is rotated to the right, the lead screw 130 may be moved upward. Conversely, when the knob 120 is rotated to the left, the lead screw 130 may move downward. For the movement, the lead screw 130 may not rotate together with the knob 120 . A user may adjust the position of the lead screw 130 by rotating the knob 120 .

The ultrasonic irradiation movable body 210 may irradiate ultrasonic waves while moving along the rotational axis of the knob 120 together with the lead screw 130 . Accordingly, the ultrasound focusing point SP may be moved upward or downward. That is, referring to FIG. 6 , the position of the ultrasonic focusing point SP may be moved by a predetermined distance d by rotation of the knob 120 and movement of the lead screw 130 .

According to one embodiment of the present invention, the knob 120 and the lead screw 130 may be coupled to each other by thread engagement, and the threads of the knob 120 and the lead screw 130 may come into close contact with each other by elasticity. can

As described above, in order to move the lead screw 130 by rotation of the knob 120 , threads corresponding to each other may be provided on an inner circumferential surface of the knob 120 and an outer circumferential surface of the lead screw 130 . In this case, if the thread of the knob 120 and the thread of the lead screw 130 are in excessive contact with each other, the lead screw 130 cannot be moved, that is, the thread of the knob 120 and the thread of the lead screw 130 A certain amount of gap must be provided between them.

However, vibration may occur during ultrasonic output, and the ultrasonic irradiation movable body 210 may be shaken and moved due to the vibration, and the ultrasonic focusing point SP may also be shaken and moved due to the vibration of the ultrasonic irradiation movable body 210. . That is, the position of the ultrasonic focusing point SP may be continuously changed due to the vibration and gap.

To prevent this, the thread of the knob 120 and the thread of the lead screw 130 may come into close contact with each other by an elastic force.

In one aspect, the lead screw 130 may be pushed upward by elasticity. Referring to FIG. 3 , a groove 131 may be provided below the lead screw 130 , and an elastic member 133 may be inserted into the groove 131 . In addition, the body portion 100 may be provided with a guide pin 135, a portion of which is inserted into the groove 124 and presses the elastic member 133 upward. As a result, the lead screw 130 receives an elastic force upward, and the thread of the knob 120 and the thread of the lead screw 130 come into close contact with each other to prevent the ultrasonic focusing point SP from shaking and moving despite the gap. can In other words, in a state in which the knob 120 is not rotated, the ultrasonic treatment apparatus according to the present invention can irradiate ultrasonic waves at a constant position without shaking or vibration.

Accordingly, the ultrasonic irradiation movable body 210 may be detachably coupled to the lead screw 130 . Meanwhile, at least one of the magnet 219 provided in the ultrasonic irradiation movable body 210 and the magnet 137 provided in the lead screw 130 may be a metal member attached to the magnet. In this case, since the magnet and the metal member attached to the magnet are detachably coupled to each other, the ultrasonic irradiation movable body 210 may be detachably coupled to the lead screw 130 .

When the ultrasonic irradiation movable body 210 is coupled to the lead screw 130 by magnetic force, the ultrasonic irradiation movable body 210 may also move according to the movement of the lead screw 130 . Conversely, when the ultrasonic irradiation movable body 210 is separated from the lead screw 130, the cartridge unit 200 provided with the ultrasonic irradiation movable body 210 may be separated from the main body 100. Then, the user can separate and replace only the cartridge unit 200 including consumable parts, and it may be possible to separate and wash only the cartridge unit 200 after use.
