[0028] The utility model provides an ultrasonic treatment head 100.

[0029] Reference Figures 1 to 3The ultrasonic treatment head 100 comprises a shell 1, a sleeve 2, a water storage structure 3, a front cover 4 and a sensor 5. The sleeve 2 is mounted on the shell 1. The water storage structure 3 is partially inserted into the sleeve 2 to be in sliding connection with the sleeve 2, so that the water storage structure 3 moves along the axial direction of the sleeve 2 under the constraint of the sleeve 2. The front cover 4 is connected with the water storage structure 3 to move together with the water storage structure 3. The sensor 5 is arranged between the front cover 4 and the shell 1 to detect the pressure between the front cover 4 and the shell 1.

[0030] In the ultrasonic treatment head 100, the water storage structure 3 is arranged in the shell 1 and is configured to be movable relative to the shell 1. The water storage structure 3 is partially inserted into the sleeve 2 to be in sliding connection with the sleeve 2, so that the water storage structure 3 moves along the axial direction of the sleeve 2 under the constraint of the sleeve 2. Then, the front cover 4 is connected with the water storage structure 3 to form a movable whole with the water storage structure 3. An energy generator is arranged in the water storage structure 3 and is soaked in the liquid acoustic medium. An end surface of the water storage structure 3 is provided with a sound transmission film for sealing. An end surface of the front cover 4 is arranged in the same plane as the plane where the sound transmission film is arranged. In use, the sound transmission film is in contact with the skin. The ultrasonic energy is transmitted to the skin through the acoustic medium and the sound transmission film, so that the ultrasonic treatment is realized.

[0031] In order to avoid that the energy is released when the treatment head does not contact the skin, the ultrasonic treatment head 100 is provided with the sensor 5 between the front cover 4 and the shell 1. The sensor 5 can be a piezoresistive sensor 5, which is electrically connected with a control mainboard (not marked) and an energy generator (not marked) in the treatment head. When the control mainboard receives the pressure change signal of the sensor 5, the control mainboard controls the energy generator to emit energy.

[0032] In the initial state, there is a small gap between the front cover 4 and the shell 1. The front cover 4 is separated from the sensor 5, and the ultrasonic treatment head 100 is in a non-working state. When the front cover 4 is in contact with the skin and is pressed, the front cover 4 will drive the water storage structure 3 to move together towards the shell 1, so that the front cover 4 is in contact with the sensor 5. The impedance pressure value of the sensor 5 changes, the control mainboard receives the pressure change signal of the sensor 5, and the energy generator is controlled to emit energy. When the front cover 4 is away from the skin, the pressure applied to the front cover 4 disappears, the front cover 4 is separated from the sensor 5, the control mainboard receives the signal and controls the energy generator to stop emitting energy.

[0033] In order to avoid the jamming phenomenon caused by the deviation of the front cover 4 and the water storage structure 3 during movement, the ultrasonic treatment head 100 inserts the water storage structure 3 into the hollow channel of the sleeve 2, and the circumferential wall of the water storage structure 3 is in sliding contact with the inner circumferential wall of the sleeve 2. Therefore, the water storage structure 3 moves along the axis direction of the sleeve 2 under the constraint of the sleeve 2, so as to ensure that the water storage structure 3 and the front cover 4 always move along the axis direction of the sleeve 2, thereby ensuring the stability of the movement of the water storage structure 3 and the front cover 4, and effectively avoiding the jamming problem caused by deviation.

[0034] With reference to Figure 1 In some embodiments of the present application, the shell 1 is provided with a clearance 11, the sleeve 2 includes a barrel 21 and a boss 22 protruding from the circumferential side of the barrel 21, the barrel 21 is arranged in the clearance 11, and the boss 22 is fixedly connected with the shell 1. Then, the water storage structure 3 is partially inserted into the barrel 21, and the water storage structure 3 moves along the axis direction of the barrel 21 under the constraint of the barrel 21.

[0035] The water storage structure 3 includes a main body 31 and a pressing portion 32 connected with each other, the main body 31 is partially inserted into the sleeve 2, and the pressing portion 32 protrudes from the sleeve 2, at this time, the front cover 4 is sleeved on the pressing portion 32 to move together with the water storage structure 3.

[0036] In this embodiment, the shell 1 is provided with a clearance 11, the sleeve 2 is arranged in the clearance 11 and connected with the shell 1, and the main body 31 of the water storage structure 3 is partially inserted into the sleeve 2 to make the pressing portion 32 protrude from the sleeve 2. Then, the front cover 4 is sleeved on the pressing portion 32 to be connected with the water storage structure 3, and the end surface of the pressing portion 32 is provided with a sound permeable film for sealing.

[0037] With reference to Figure 2 And Figure 4 The front cover 4 includes a fitting portion 41 and a limiting portion 42 connected with each other, the fitting portion 41 is sleeved on the pressing portion 32 and is fixedly limited with the pressing portion 32, the limiting portion 42 is connected with the shell 1, the sleeve 2 is located between the limiting portion 42 and the main body 31, and the sensor 5 is arranged between the limiting portion 42 and the shell 1.

[0038] In this embodiment, the sleeve 2 is arranged between the limiting portion 42 of the front cover 4 and the main body 31 of the water storage structure 3, the inner circumferential wall of the sleeve 2 is in sliding contact with the outer circumferential wall of the main body 31, and the outer circumferential wall of the sleeve 2 is in sliding contact with the inner circumferential wall of the limiting portion 42, so that the sleeve 2 not only limits and guides the water storage structure 3, but also limits and guides the front cover 4, thereby further improving the stability of the movement of the front cover 4 and the water storage structure 3.

[0039] In order to realize the limiting of the front cover 4 and the water storage compartment structure 3, in an embodiment of the utility model, the cross section size of the pressing part 32 gradually reduces from one end towards the main body part 31 to one end away from the main body part 31, the cross section size of the abutting part 41 gradually reduces from one end towards the limiting part 42 to one end away from the limiting part 42, and the inner circumferential wall of the abutting part 41 and the outer circumferential wall of the pressing part 32 abut and limit. That is, the pressing part 32 and the abutting part 41 both adopt the gradually reduced cross section design, which not only can simplify the assembly process of the front cover 4 and the water storage compartment structure 3, but also can ensure the coaxiality of the front cover 4 and the water storage compartment structure 3, avoiding the displacement or rotation of the water storage compartment structure 3 in the moving process.

[0040] Regarding the installation of the sensor 5, the sensor 5 is arranged between the limiting part 42 and the shell 1, and specifically refers to Figure 2 and Figure 4 , the inner circumferential wall of the limiting part 42 is provided with a stepped part 421, the stepped part 421 and the sleeve 2 and the shell 1 form an installation gap, and the sensor 5 is arranged in the installation gap.

[0041] The stepped part 421 has a contact surface 4211 arranged opposite to the sensor 5. In the initial state, the contact surface 4211 and the sensor 5 are separated from each other, and the ultrasonic treatment head 100 is in a non-working state; when the front cover 4 is in contact with the skin and is pressed, the front cover 4 will drive the water storage compartment structure 3 to move towards the shell 1 together, and in this process, the contact surface 4211 will move towards the sensor 5 and contact and press the sensor 5, the control mainboard receives the pressure change signal of the sensor 5 to control the energy generator to emit energy; when the front cover 4 leaves the skin, the pressure applied to the front cover 4 disappears, the contact surface 4211 is separated from the sensor 5, and the control mainboard receives the signal and controls the energy generator to stop emitting energy.

[0042] In an embodiment of the utility model, a contact point 4212 is protruded on the contact surface 4211, and the contact point 4212 is used for contacting and pressing the sensor 5. The arrangement of the contact point 4212 makes the front cover 4 first contact the sensor 5 in the case of slight displacement, thereby improving the sensitivity of the sensor 5.

[0043] Referring to Figure 2 and Figure 5 , an embodiment of the ultrasonic treatment head 100 further comprises a gasket 6, which can be a rubber pad or a silica gel pad, and is arranged in the installation gap and between the sensor 5 and the shell 1. The gasket 6 is used for providing buffer for the sensor 5, so that the sensor 5 can deform freely under the action of the pressing force, thereby causing the resistance value to change obviously and improving the sensitivity of the sensor 5.

[0044] Further, the gasket 6 is provided with a clearance groove 61 on the side away from the sensor 5, and the clearance groove 61 is provided away from the contact 4212. The clearance groove 61 can make the sensor 5 recess into the clearance groove 61 together with the gasket 6 when the pressing stroke of the contact 4212 is long and the pressing force is too large, so that the sensor 5 is not damaged.

[0045] With reference to Figure 3 The ultrasonic treatment head 100 further comprises an elastic member 7, which can be one of a spring, a rubber pad and a bellows. The elastic member 7 is arranged between the front cover 4 and the shell 1, and the front cover 4 drives the water storage compartment to move together by extruding the elastic member 7.

[0046] Taking the elastic member 7 as a spring as an example, the spring is arranged in a ring around the edge of the clearance 11, and one end of the spring is connected to the shell 1 and the other end is connected to the front cover 4. In the initial state, the front cover 4 is separated from the sensor 5 under the support of the spring. When the front cover 4 contacts the skin, the front cover 4 drives the water storage compartment structure 3 to move together towards the sensor 5 by extruding the spring. When the front cover 4 leaves the skin, the front cover 4 drives the water storage compartment structure 3 to automatically reset under the drive of the spring, so as to realize the automatic separation of the front cover 4 and the sensor 5, thereby realizing the switching of the working state of the ultrasonic treatment head 100.
