[0034] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0035] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0036] like Figures 1 to 4 As shown, this embodiment provides a handheld beauty device 1, which is applied to a skin beauty instrument. The skin beauty instrument includes a negative pressure device 2 and a connecting duct 3. The handheld beauty device 1 includes a massage head 110 and a handle 120. The massage head 110 and the handle 120 are both shell structures with openings at both ends. One end of the handle 120 is connected to the connecting duct 3, and the other end is detachably connected to the massage head 110; the massage head 110, the handle 120, the connecting duct 3 and the negative pressure device 2 are connected in sequence to form a suction channel. When the opening on the massage head 110 away from the end of the handle 120 is sealed against the skin to be massaged, the suction channel is in a negative pressure state; a sealing switch is provided on the suction channel, and the suction channel selectively maintains a negative pressure state or disconnects the negative pressure state through the sealing switch.

[0037] The negative pressure device 2 can be used to suck air to form a negative pressure in the suction channel. The negative pressure device 2 can be a vacuum pump. When the opening at one end of the massage head 110 away from the handle 120 is in close contact with the skin, the suction channel is in a sealed state. The vacuum pump works to extract the air in the suction channel and discharge it to the outside. The gas in the suction channel becomes less and less, presenting a negative pressure, which in turn has a pulling effect on the blood vessels and nerves in the skin, thereby playing the role of dredging the meridians or accelerating blood circulation, enhancing metabolism, and thus enhancing the body's immunity.

[0038] The massage head 110 may be, but is not limited to, a metal shell or a non-metal shell. For example, the massage head 110 is a metal shell, and the massage head 110 is a shell structure with two openings at both ends and an inner cavity, wherein the opening at one end is connected to the handle 120, and the opening at the other end is used to abut against the skin to be massaged.

[0039] The handle 120 may be, but is not limited to, a metal shell or a non-metal shell. For example, the handle 120 is a metal shell, and the handle 120 is a shell structure with two ends opened, and the two ends of the handle 120 are respectively connected to the massage head 110 and the connecting conduit 3. The length and size of the handle 120 should be suitable for the user to hold, so as to flexibly control the movement of the massage head 110 on the skin. In addition, the massage head 110 is detachable relative to the handle 120, and the user can select massage heads 110 of different sizes according to the skin part to be massaged. For example, a massage head 110 with a smaller volume can be used for massage of small parts such as face, waist and abdomen, neck, lymph, arms, arms and legs, and a massage head 110 with a larger volume can be used for massage of large parts such as back waist and abdomen; in addition, the massage head 110 and the handle 120 are detachable, and the massage head 110 can be independently deeply disinfected to avoid cross contact. The massage head 110 can be a disposable product, which can be replaced individually and in time without overall replacement, thereby improving the rational use of resources.

[0040] The sealing switch can be used to change the negative pressure state of the suction channel. Exemplarily, the sealing switch is set on the massage head 110, and the sealing switch can be manually switched. When the sealing switch is in the on state, the suction channel is connected to the external atmosphere through the sealing switch, the air in the suction channel increases, and the massage head 110 cannot pull the skin. The sealing switch is switched from the on state to the off state, and the suction channel is quickly switched to the negative pressure state, so that the massage head 110 pulls the skin. Based on the manual switching of the working state of the sealing switch on the massage head 110, the negative pressure state of the suction channel is quickly switched, so that the massage head 110 can be quickly withdrawn or adsorbed on the skin to massage different skin parts.

[0041] The handheld massage head 110 in the above embodiment, the massage head 110 and the handle 120 are both shell structures with openings at both ends. The massage head 110, the handle 120, the connecting conduit 3 and the negative pressure device 2 are connected in sequence to form a suction channel. When the opening on the end of the massage head 110 away from the handle 120 is sealed against the skin to be massaged, the negative pressure device 2 works to extract the air in the suction channel and discharge it to the outside. The gas in the suction channel becomes less and less, presenting a negative pressure, thereby pulling the blood vessels and nerves in the skin; the handle 120 is detachably connected to the massage head 110, and the suction channel is used to remove the air from the suction channel. The user can choose massage heads 110 of different sizes according to the skin part to be massaged. In addition, the massage head 110 and the handle 120 are detachable, and the massage head 110 can be independently deeply disinfected to avoid cross contact. The massage head 110 can also be a disposable item and can be replaced individually and in time without replacing the entire head. A sealing switch is provided on the suction channel, and the sealing switch can quickly change the working state of the sealing switch by manual switching, thereby quickly switching the negative pressure state of the suction channel, so that the massage head 110 can be quickly withdrawn from or adsorbed on the skin to massage different skin parts.

[0042] like Figures 2 to 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that: a first through hole 101 is opened on the side wall of the massage head 110 or the side wall of the handle 120, the first through hole 101 forms a sealed switch, and the first through hole 101 is connected to the suction channel.

[0043] The first through hole 101 may be provided on the side wall of the massage head 110 or the side wall of the handle 120. For example, the first through hole 101 is provided on the side wall of the massage head 110, and the first through hole 101 is connected to the first cavity 103 of the massage head 110. When the user holds the handle 120, the first through hole 101 may be blocked by one of the fingers to prevent the external atmosphere from being connected to the suction channel through the first through hole 101, and under the action of the negative pressure device 2, the suction channel is in a negative pressure state; when the finger blocking the first through hole 101 is removed, the suction channel is quickly connected to the external atmosphere, and the pulling effect of the massage head 110 on the skin gradually decreases; based on the method of using the first through hole 101 provided on the side wall of the massage head 110 as a sealing switch, not only is the structure simple and the cost low, but the user can also flexibly switch the working state of the sealing switch manually.

[0044] like Figure 3 to Figure 4 As shown, in addition to the features of the above-mentioned embodiment, the present embodiment is further defined as follows: a first opening 102, a first cavity 103 and a second opening 14 which are connected in sequence are formed in the massage head 110, a first thread is formed at the second opening 14 of the massage head 110, a second thread is formed at the end of the handle 120 away from the connecting conduit 3, and the massage head 110 and the handle 120 are threadedly connected via the first thread and the second thread.

[0045] The first thread on the massage head 110 and the second thread on the handle 120 can be matched and connected. Since the massage head 110 and the handle 120 are assembled by threaded connection, the sealing of the connection between the massage head 110 and the handle 120 can be ensured, and the negative pressure state of the suction channel is prevented from failing due to the connection between the massage head 110 and the handle 120 and the external atmosphere. At the same time, the threaded connection makes the disassembly and assembly between the massage head 110 and the handle 120 simple and reliable.

[0046] like Figure 2 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the first opening 102 is in a wide-side arc shape.

[0047] The first opening 102 of the massage head 110 can be directly placed against the skin to be massaged. Since the first opening 102 is designed in a wide arc shape, the contact area between the mouth of the massage head 110 and the skin is increased, which reduces the pain caused by the massage head 110 when cupping and increases the comfort of the massage head 110 when cupping.

[0048] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment is further defined as follows: the handle 120 is cylindrical.

[0049] The handle 120 can be held by a user to drive the massage head 110 to move along with the handle 120. The handle 120 is cylindrical in shape, so that the handle 120 is easy to hold and control.

[0050] like Figure 3 and Figure 4 As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines: the handle 120 includes a handle body 121 and a connecting column 122, the connecting column 122 is connected to an end of the handle body 121 away from the massage head 110, the diameter of the connecting column 122 matches the diameter of the connecting conduit 3, and the connecting column 122 is at least partially inserted into the pipe of the connecting conduit 3.

[0051] The handle 120 is connected to the connecting conduit 3 via a connecting column 122. Specifically, the connecting column 122 is connected to an end of the handle body 121 away from the massage head 110, and the connecting column 122 and the handle body 121 can be an integrally formed structure. The connecting column 122 and the handle body 121 are interconnected, and the diameter of the connecting column 122 is slightly smaller than the diameter of the connecting conduit 3, so that the connecting column 122 can be inserted into the pipe of the connecting conduit 3, and the handle 120 is directly inserted into the pipe of the connecting conduit 3 to achieve a detachable connection.

[0052] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the connecting conduit 3 is an elastic hose, an annular protrusion 1221 is provided on the connecting column 122, and the distance between the outer wall of the annular protrusion 1221 and the connecting column 122 gradually increases toward the massage head 110.

[0053] The connecting conduit 3 can be elastically deformed. Exemplarily, the connecting conduit 3 is made of silicone material, and when the connecting column 122 is inserted into the pipe of the connecting conduit 3, even if the diameter of the connecting pipe is slightly smaller than the diameter of the connecting column 122, the connecting conduit 3 is elastically deformed under the action of mutual extrusion, so that the connecting column 122 can be smoothly inserted into the pipe; in addition, based on the annular protrusion 1221 provided on the connecting column 122, and the distance between the outer wall of the annular protrusion 1221 and the connecting column 122 gradually increases toward the massage head 110, the connecting conduit 3 is elastically deformed, and the inner wall of the pipe and the connecting column 122 are interference-fitted, ensuring the sealing performance of the connection between the connecting column 122 and the connecting conduit 3.

[0054] like Figure 3 and Figure 4 As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines: the handle 120 also includes a locking piece 123, the locking piece 123 is a shell structure with openings at both ends, the locking piece 123 is connected to one end of the handle body 121 close to the connecting column 122, the opening of the locking piece 123 at the end away from the handle 120 is trumpet-shaped and matches the annular protrusion 1221, and the connecting conduit 3 mounted on the connecting column 122 is partially clamped between the annular protrusion 1221 and the locking piece 123.

[0055] Among them, the locking piece 123 can be used to further strengthen the sealing between the connecting conduit 3 and the connecting column 122; specifically, the inner wall of the locking piece 123 is formed with a trumpet-shaped opening at one end away from the handle body 121, and the opening direction of the trumpet is toward the direction of the annular protrusion 1221. When the connecting column 122 is inserted into the pipe of the connecting conduit 3, the annular protrusion 1221 causes the pipe to elastically deform. On this basis, the connecting conduit 3 mounted on the connecting column 122 is clamped between the locking piece 123 and the connecting column 122. The locking piece 123 applies a force to the connecting conduit 3, so that the connecting conduit 3 is tightly attached to the connecting column 122, thereby further strengthening the sealing between the connecting conduit 3 and the connecting column 122.

[0056] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further defines: a third thread is provided at one end of the handle body 121 close to the connecting column 122, a fourth thread is provided on the inner wall of the locking member 123, and the handle body 121 and the locking member 123 are threadedly connected via the third thread and the fourth thread.

[0057] Among them, the third thread on the handle body 121 and the fourth thread on the locking piece 123 can be matched and connected. The handle body 121 and the locking piece 123 can be quickly disassembled and assembled by threaded connection; in addition, before the connecting conduit 3 is transferred and connected with the handle 120, the connecting conduit 3 must first be passed through the locking piece 123, and then the connecting conduit 3 is sleeved on the connecting column 122, and then the locking piece 123 is threadedly connected with the handle body 121. Since the opening of the locking piece 123 at the end away from the handle 120 is trumpet-shaped and matches the annular protrusion 1221 on the connecting column 122, as the locking piece 123 is screwed deeper relative to the handle body 121, the squeezing force of the inner wall of the locking piece 123 on the connecting conduit 3 becomes greater and greater, thereby further strengthening the seal between the connecting conduit and the connecting column 122.

[0058] like Figure 1 As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines: the skin beauty instrument also includes a filter device 4, the filter device 4 is arranged between the negative pressure device 2 and the connecting conduit 3, and the negative pressure device 2 is connected to the connecting conduit 3 through the filter device 4, and the filter device 4 is used to collect skin exfoliation.

[0059] The filter device 4 can be used to collect the dandruff or secretions shed when the massage head 110 pulls the skin. Exemplarily, the filter device 4 is composed of a waste bottle and a filter screen, wherein the waste bottle is connected to the negative pressure device 2 and the connecting conduit 3 respectively, and the filter screen is located in the waste bottle. The dandruff or secretions shed by the skin are filtered by the filter screen and stay in the waste, preventing the dandruff or secretions from entering the negative pressure device 2.

[0060] like Figure 1 As shown, this embodiment provides a skin beauty instrument, including: the above-mentioned handheld beauty device 1, a negative pressure device 2, a connecting tube 3, a filter device 4 and a host 5, the negative pressure device 2 is controlled by the host 5, the handheld beauty device 1 is hung on the host 5, and the handheld beauty device 1, the connecting tube 3, the filter device 4, and the negative pressure device 2 are connected in sequence.

[0061] For the detailed description of the handheld beauty device 1 , the negative pressure device 2 , the connecting conduit 3 and the filtering device 4 , please refer to the description of the above embodiment, which will not be repeated here.

[0062] The main unit may be composed of at least a control device, a power source, a pipeline, a liquid storage bottle containing different essences, and other types of beauty handles. Under the control of the control device, the power source can provide power to transport the essence on the corresponding liquid storage bottle to the corresponding beauty handle through the pipeline. Exemplarily, the multiple beauty handles may be a radio frequency handle that promotes skin firming, a cleaning handle that can deeply clean the skin and remove skin dead skin, an ultrasonic whitening handle that can improve skin quality, a skin rejuvenation handle that can promote pore contraction, and an oxygen enrichment handle that can clean the skin and have an anti-inflammatory effect, etc.

[0063] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
