Description

Radio frequency beauty equipment

Technical Field

The utility model relates to the technical field of medical treatment, in particular to radio frequency beauty equipment.

Background

In the radio frequency beauty treatment mode, the heat-gem is a non-invasive radio frequency beauty treatment device, and can transmit a high-frequency radio frequency signal to the skin so as to enable the deep layer of the skin to generate a heating effect under the action of electronic motion, thus being capable of breaking hydrogen bonds in collagen tissues and changing triple helix structures in the collagen tissues, and further leading the collagen tissues to shrink instantly. The collagen tissue can start a wound healing response mechanism in the skin after thermal injury, so that the activity of the fiber cells is stimulated, so that the fiber cells can synthesize new collagen tissue, and the reconstruction and thickening of the dermis of the skin are promoted. During radio frequency therapy, heat may be transferred to the dermis layer of the skin by thermal conduction. In order to prevent the skin layer from being scalded due to overhigh temperature, the conventional radio frequency cosmetic equipment generally adopts an impact jet flow mode to release a refrigerant to the skin surface, thereby reducing the temperature of the skin and providing anti-scalding protection for the skin.

The prior radio frequency beauty equipment comprises a working head and a handle which are connected with each other and form a refrigerant channel inside. In order to prevent leakage of the refrigerant, it is necessary to seal the contact position between the working head and the handle. The traditional sealing mode is to set the abutting position of the refrigerant channel of the working head and the abutting position of the refrigerant channel of the handle as inclined planes, and to contact the inclined planes of the refrigerant channel of the working head and the handle to form taper sealing. However, the pressure of the refrigerant in the refrigerant channel is generally greater than the atmospheric pressure, and the sealing property of taper sealing between the working head and the handle is poor, so that a certain risk of refrigerant leakage exists.

It should be understood that when the working head 1 and the handle 2 are connected, the abutment of the first transmission member 11 and the second transmission member 21 means that the two are connected or only abut against each other without being connected, and the abutment position of the first transmission member 11 and the second transmission member 21 means the contact position after the connection or abutment of the first transmission member 11 and the second transmission member 21. In one embodiment, the elastomeric seal 3 is directly connected to the first transfer element 11 to secure the elastomeric seal 3 directly to the first transfer element 11. In another embodiment, the elastic seal 3 is directly connected to the second transfer element 21, so as to fix the elastic seal 3 directly to said second transfer element 21. In other embodiments, one elastic sealing member 3 is fixed to each of the first transmission member 11 and the second transmission member 21, and sealing is achieved by contact of the elastic sealing member 3 on the first transmission member 11 and the elastic sealing member 3 on the second transmission member 21.

The fixing manner of the elastic sealing member 3 on the first transmission member 11 or the second transmission member 21 is not limited in this application, and the elastic sealing member 3 is fixed by, but not limited to, gluing or hot melting.

The first delivery tube 111 is arranged on the side of the extension 112 remote from the handle 2. The extension 112 has a hollow interior. The second transfer element 21 comprises a second transfer tube 211.

As shown in fig. 4, when the working head 1 and the handle 2 are connected, that is, the first transmission member 11 and the second transmission member 21 are connected, at least a portion of the second transmission pipe 211 extends into the inner cavity of the extension 112 and abuts against the first transmission pipe 111, thereby allowing the second transmission pipe 211 and the first transmission pipe 111 to communicate to transmit the refrigerant. It should be understood that abutment of the first and second delivery tubes 111, 211 means that the two are connected or merely abut and are not connected.

In some embodiments, the elastomeric seal 3 seals the abutment between the second delivery tube 211 and the first delivery tube 111. In a specific example, the elastic seal 3 is an O-ring. The O-ring may be fixed to an end of the second conveying pipe 211 facing the first conveying pipe 111, or may be fixed to an end of the first conveying pipe 111 facing the second conveying pipe 211, so that when the second conveying pipe 211 and the first conveying pipe 111 are abutted, the O-ring may be disposed between the second conveying pipe 211 and the first conveying pipe 111 to seal an abutting position between the second conveying pipe 211 and the first conveying pipe 111 in an axial direction of the second conveying pipe 211.

The kind of the elastic sealing element 3 is not limited in the present application, and the elastic sealing element 3 may be configured as a spring plate, an elastic tube, a rubber sealing ring, or the like as needed.

In other embodiments, the elastomeric seal 3 may also seal the abutment between the second delivery tube 211 and the extension 112. In a specific example, the O-ring may be sleeved and fixed on the second conveying pipe 211. When the working head 1 is connected with the handle 2, a part of the second conveying pipe 211 extends into the extension section 112, and the O-ring is located between the outer wall of the second conveying pipe 211 and the inner wall of the extension section 112, so as to seal the abutting position between the second conveying pipe 211 and the extension section 112 in the radial direction of the second conveying pipe 211.

In a preferred embodiment, the second transmission member 21 further comprises a sleeve 212. The sleeve 212 is sleeved on the second conveying pipe 211. When the working head 1 is connected with the handle 2, a part of the second conveying pipe 211 extends out of the sleeve 212 and into the inner cavity of the extension section 112, one end of the extension section 112 is abutted with one end of the sleeve 212, an elastic sealing element 3 is arranged between the sleeve 212 and the extension section 112, and the elastic sealing element 3 is used for sealing the abutting position of the sleeve 212 and the extension section 112 in the axial direction of the second conveying pipe 211. In an example, when the inner diameter of the sleeve 212 is smaller than the outer diameter of the extension 112, the O-ring may be sleeved on the second conveying pipe 211 and fixed at the end of the sleeve 212 facing the extension 112 or at the end of the extension 112 facing the sleeve 212, so configured that the O-ring may be disposed between the sleeve 212 and the extension 112 to seal the abutting position between the sleeve 212 and the extension 112 in the axial direction of the second conveying pipe 211.

It will be appreciated that if the elastic seals 3 are provided at different positions, the number of corresponding elastic seals 3 is plural.

In more detail, the first transfer pipe 111 has a first through hole penetrating axially, and the second transfer pipe 211 has a second through hole (not numbered) penetrating axially. When the working head 1 is connected to the handle 2, the end of the second delivery pipe 211 abuts against the end of the first delivery pipe 111, so that the first through hole communicates with the second through hole to transmit the refrigerant.

The sizes of the first and second conveying pipes 111 and 211 are not limited in the present application, and the sizes of the first and second conveying pipes 111 and 211 may be set according to the conveying amount of the refrigerant. Referring to fig. 4, in this embodiment, in order to facilitate the transmission of the refrigerant, the inner diameter size of the first through hole and the inner diameter size of the second through hole may be set to be equal. In other embodiments, the inner diameter dimension of the first through hole and the inner diameter dimension of the second through hole may also be set to be unequal.

Referring to fig. 2 and 6, the second transfer member 21 further includes a support member 213, and the sleeve 212 and the second transfer tube 211 are fixedly connected by the support member 213. In this embodiment, the supporting member 213 is a circular bracket, and the ends of the second conveying pipe 211 and the sleeve 212 may be fixed at the center of the circular bracket, respectively, to facilitate sealing and connection of the first conveying member 11 and the second conveying member 21.

As shown in fig. 3 to 5, and in combination with fig. 2, the handle 2 further includes a handle housing 22 and a first fixing member 23, and the handle housing 22 is connected to the supporting member 213. Referring to fig. 6, in one example, the support 213 is fixedly coupled to the handle housing 22 by bolts 214.

Further, a first fixing member 23 is fixed in the handle housing 22, and the first fixing member 23 and the sleeve 212 together form a receiving groove in which the elastic sealing member 3 is disposed. When the working head 1 and the handle 2 are connected, the extension 112 abuts the resilient seal 3. Referring to fig. 4 and 5, in the present embodiment, the first fixing member 23 has a first plane 231 and a second plane 232 for limiting the elastic sealing member 3, and the sleeve 212, the first plane 231 and the second plane 232 together form a receiving groove (not numbered) in which the elastic sealing member 3 is placed. After the working head 1 and the handle 2 are connected, the elastic sealing member 3 can abut against the extension 112 to seal the abutting position between the extension 112 and the sleeve 212, thereby preventing leakage of the refrigerant.

Preferably, the inner diameter of the elastomeric seal 3 is greater than the inner diameter of the sleeve 212. So configured, when the working head 1 and the handle 2 are connected, the elastic seal member 3 cannot be pressed into the gap between the second delivery pipe 211 and the sleeve 212 by the extension 112, so that it is possible to prevent the elastic seal member 3 from being excessively deformed due to compression at high frequencies and to reduce the service life. Of course, in other embodiments, the inner diameter of the elastomeric seal 3 may also be less than or equal to the inner diameter of the sleeve 212.

More preferably, when the elastic sealing member 3 is an O-ring, the inner diameter of the elastic sealing member 3 is smaller than the outer diameter of the extension section 112, so that when the extension section 112 contacts with the O-ring, the extension section 112 can generate a radial compression force on the O-ring, so that the O-ring is pressed to be more closely attached to the inner wall of the accommodating groove, and the O-ring can be more closely attached to the sleeve 212 after being pressed, thereby further improving the tightness of the O-ring to the abutting position of the sleeve 212 and the extension section 112. In other embodiments, the inner diameter of the elastomeric seal 3 may also be equal to the outer diameter of the extension 112.

Referring to fig. 4 and 6, and in combination with fig. 1, the working head 1 further includes a working head housing 12, and the first transmission member 11 is fixed in the working head housing 12. The handle 2 further includes a moving portion 24, the moving portion 24 being movably provided on the handle housing 22, the moving portion 24 being capable of being driven to be connected to or disconnected from the head housing 12, so that the connection or disconnection of the head 1 and the handle 2 can be achieved by driving the moving portion 24. The number of the moving parts 24 is not limited in the present application, and in the present embodiment, the number of the moving parts 24 is two, and the two moving parts 24 may be symmetrically disposed along the axis of the sleeve 212. In other embodiments, the number of moving portions 24 may be 1, 3, or others.

In this embodiment, the catch 242 may be connected to the release button 241 along the axial direction of the second conveying pipe 211, the catch 242 may be driven to be located in the catch groove 121 to achieve connection of the working head 1 and the handle 2, and the catch 242 may also be driven to be separated from the catch groove 121 to achieve separation of the working head 1 and the handle 2.

Further, the moving part 24 further includes an elastic member 243, the second fixing member 25 is disposed inside the handle housing 22, the elastic member 243 is disposed between the release button 241 and the second fixing member 25, one end of the elastic member 243 abuts against one end of the release button 241, and the other end abuts against the second fixing member 25. In this embodiment, the other end of the release button 241 extends out of the handle housing 22. When the release button 241 is forced to move relative to the second fixing member 25, the elastic member 243 is elastically deformed; when the release button 241 is released from the force, the elastic force of the elastic member 243 drives the release button 241 to reset, so that the movement and automatic reset of the release button 241 can be realized.

It should be understood that the first fixing member 23 and the second fixing member 25 may be integrally formed or separately formed, and in this embodiment, the first fixing member 23 and the second fixing member 25 are integrally formed as a third fixing member (not numbered) and fixed in the handle housing 22.
