The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this description, the terms "and / or" includes any and all combinations of one or more of the associated listed items.
[0037] In combination Figures 1 to 3 The utility model discloses a handle 100 of beauty instrument, including shell 110, first flow guide pipe 120, second flow guide pipe 130 and flow guide column 140 of current limiting buffer. Wherein first flow guide pipe 120 and second flow guide pipe 130 are collectively called flow guide pipe here. Shell 110 is hollow pen -like, and defines flow guide pipe installation space 111. Wherein shell 110 upper and lower ends are all set the opening, and shell 110 upper end installs handle round head 112. Shell 110 upper end perimeter is equipped with the annular mounting table of upward protruding, and handle round head 112 perimeter is equipped with the annular outer wall of downward protruding, and the annular outer wall is connected with the annular mounting table plug -in, and the inner wall of annular outer wall and the outer wall of annular mounting table are connected through interference fit plug -in. Handle round head 112 is equipped with the flow guide hole 1121 of the communication installation space 111 inside and outside, and the flow guide hole 1121 is communicated from top to bottom. Shell 110 lower end is flow guide pipe entrance 1122. First flow guide pipe 120 one end is inserted into installation space 111 from flow guide pipe entrance 1122, and extends to correspond with flow guide hole 1121 upwards. Second flow guide pipe 130 is the hose and is arranged in installation space 111, and one end of second flow guide pipe 130 is connected with first flow guide pipe 120 through flow guide pipe fixing band 160, wherein, the upper end of first flow guide pipe 120 is inserted into second flow guide pipe 130 from bottom to top, and flow guide pipe fixing band 160 is tightly second flow guide pipe 130 outer wall around first flow guide pipe 120 and second flow guide pipe 130 insertion site exterior. One end of second flow guide pipe 130 corresponds to be connected to flow guide hole 1121. Second flow guide pipe 130 is equipped with current limiting buffer flow guide column 140. Current limiting buffer flow guide column 140 is hollow, and is inserted into second flow guide pipe 130, and current limiting buffer flow guide column 140 jams second flow guide pipe 130, and the liquid in second flow guide pipe 130 can only flow along the hollow hole of current limiting buffer column, and the diameter of water flow passage is reduced to control the liquid outflow of flow guide pipe.
[0038] In combination Figures 1 to 3 As shown in some embodiments, the current limiting buffer flow guide column 140 is a hollow short pipe. The current limiting buffer flow guide column 140 is set as a hollow pipe, and the restriction of the flow size in the second flow guide pipe 130 is controlled by controlling the hollow diameter of the current limiting buffer flow guide column 140. The current limiting buffer flow guide column 140 is set as a short pipe, which facilitates the insertion of the current limiting buffer flow guide column 140 into the second flow guide pipe 130, and reduces the friction between the current limiting buffer flow guide column 140 and the inner wall of the second flow guide pipe 130 during the insertion process.
[0039] In combination Figures 1 to 3As shown, in some embodiments, the inner diameter of the flow-limiting buffer guide column 140 is 0.3 to 0.6 times the inner diameter of the second flow guide tube 130. Since the inner diameter of the second flow guide tube 130 is small, setting the inner diameter of the flow-limiting buffer guide column 140 to be 0.3 to 0.6 times the inner diameter of the second flow guide tube 130 can ensure liquid flow using a hollow structure while ensuring the wall thickness of the flow-limiting buffer guide column 140. If the wall thickness of the flow-limiting buffer guide column 140 is too large, the hollow inner diameter will be too small, making it difficult to discharge water. If the wall thickness of the flow-limiting buffer guide column 140 is too thin, it will affect the flow-limiting function. Setting the inner diameter of the flow-limiting buffer guide column 140 to be 0.3 to 0.6 times the inner diameter of the second flow guide tube 130 can improve the flow to be 0.3 to 0.6 times the original flow of the second flow guide tube 130 when using a single flow-limiting buffer guide column 140 for flow limiting.
[0040] In some embodiments, the inner diameter of the flow-limiting buffer guide column 140 is 0.3 times, or 0.4 times, or 0.5 times, or 0.6 times the inner diameter of the second flow guide tube 130. When the inner diameter of the flow-limiting buffer guide column 140 is 0.3 times the inner diameter of the second flow guide tube 130, the flow of the second flow guide tube 130 can be limited to approximately 0.3 times the original flow. Similarly, the flow can be controlled to be 0.4 times, or 0.5 times, or 0.6 times the original flow to achieve different flow-limiting effects.
[0041] In combination Figures 1 to 3 As shown, in some embodiments, the length of the second flow guide tube 130 is at least 3 to 6 times the length of the flow-limiting buffer guide column 140. In some embodiments, the length of the second flow guide tube 130 is 3 times, or 4 times, or 5 times, or 6 times the length of the flow-limiting buffer guide column 140. When the length of the second flow guide tube 130 is 3 times the length of the flow-limiting buffer guide column 140, one flow-limiting buffer guide column 140 can be inserted into the second flow guide tube 130. The distance between the upper end of the flow-limiting buffer guide column 140 and the upper end of the second flow guide tube 130 is the same as the length of the flow-limiting buffer guide column 140, and the distance between the lower end of the flow-limiting buffer guide column 140 and the lower end of the second flow guide tube 130 is also the same as the length of the flow-limiting buffer guide column 140. This allows liquid to flow into the second flow guide tube 130 and then into the flow-limiting buffer guide column 140. After flowing out of the flow-limiting buffer guide column 140, the liquid will not immediately flow into the flow guide hole 1121. Instead, it will flow in the second flow guide tube 130 for a certain distance before flowing into the flow guide hole 1121, thereby ensuring the continuity of the liquid flowing out of the flow guide hole 1121.
[0042] In combination Figures 1 to 3As shown, in some embodiments, the flow-limiting buffer guide column 140 is outwardly convex in the middle of both ends to form an outward guide slope 141. The flow-limiting buffer guide column 140 is made of metal alloy or plastic material, and both ends of the flow-limiting buffer guide column 140 are conical, and the middle is outwardly convex, to facilitate the insertion of the flow-limiting buffer guide column 140 into the second flow guide pipe 130, with the end cone inserted into the second flow guide pipe 130 first, and gradually inserted into the second flow guide pipe 130 through the guide slope 141, which can avoid damage to the second flow guide pipe 130 during insertion of the flow-limiting buffer guide column 140. The second flow guide pipe 130 is a flexible tube, which can be squeezed during removal of the flow-limiting buffer guide column 140, so that the outer wall of the second flow guide pipe 130 exerts an upward or downward pushing force on the flow-limiting buffer guide column 140 through the guide slope 141. The junction between the guide slope 141 and the flow-limiting buffer guide column 140 is smooth, which prevents the flow-limiting buffer guide column 140 from damaging the inner wall of the second flow guide pipe 130.
[0043] In combination Figures 1 to 3 As shown, in some embodiments, the flow-limiting buffer guide column 140 is a plurality of flow-limiting buffer guide columns 140, which are sequentially and spacedly arranged in the second flow guide pipe 130. The sequential arrangement of multiple flow-limiting buffer guide columns 140 in the second flow guide pipe 130 can ensure the flow-limiting buffer effect.
[0044] In combination Figures 1 to 3 As shown, in some embodiments, the cosmetic instrument handle 100 further comprises a quick-connect air nozzle 150 for connecting the flow guide hole 1121 and the second flow guide pipe 130. The quick-connect air nozzle 150 is a hollow tube structure, the upper end of the quick-connect air nozzle 150 is inserted into the flow guide hole 1121 and is in interference fit with the inner wall of the flow guide hole 1121, the lower end of the quick-connect air nozzle 150 is inserted into the second flow guide pipe 130 and is in interference fit with the second flow guide pipe 130, liquid flows through the second flow guide pipe 130, enters the quick-connect air nozzle 150 from the upper end of the second flow guide pipe 130, flows into the flow guide hole 1121 through the quick-connect air nozzle 150, and flows out of the flow guide hole 1121. The outer wall of the quick-connect air nozzle 150 is provided with a fixing protrusion 151, which is outwardly convex along the lower outer wall of the quick-connect air nozzle 150 and is distributed along the up-down direction of the quick-connect air nozzle 150. When the lower end of the quick-connect air nozzle 150 is inserted into the second flow guide pipe 130, the fixing protrusion 151 is outwardly convex to press the inner wall of the second flow guide pipe 130 to firmly connect the quick-connect air nozzle 150 and the second flow guide pipe 130.
[0045] In combination Figures 1 to 3As shown, in some embodiments, the guide hole 1121 includes a first guide hole 1123 and a second guide hole 1124 connected sequentially in an upward direction. A quick-connect nozzle 150 is inserted into the first guide hole 1123, and the inner diameter of the second guide tube is smaller than the inner diameter of the first guide hole 1123. The lower end of the first guide hole 1123 communicates with the installation space 111, and the upper end of the quick-connect nozzle 150 is inserted into the first guide hole 1123 from bottom to top, forming an interference fit. The lower end of the second guide hole 1124 communicates with the upper end of the first guide hole 1123, and the upper end of the second guide hole 1124 communicates upward with the outside. The inner diameter of the second guide hole 1124 is smaller than that of the first guide hole 1123, and the second guide hole 1124 and the first guide hole 1123 are not coaxial, so that the connection between the first guide hole 1123 and the second guide hole 1124 forms a meandering bend 1125. When the liquid flows from the second guide pipe 130 into the guide hole 1121 through the quick-connect air nozzle 150, it first flows into the first guide hole 1123, and then flows through the first guide hole 1123 through the meandering bend 1125 and slowly flows into the second guide hole 1124. This makes the liquid flow rate after entering the second guide hole 1124 slow and prevents splashing.
[0046] Combination Figures 1 to 3 As shown, in some embodiments, the outer diameter of the flow-limiting buffer guide post 140 is larger than the inner diameter of the second flow guide tube 130 to ensure a tight fit between the flow-limiting buffer guide post 140 and the second flow guide tube 130. The second flow guide tube 130 is a flexible tube, and the flow-limiting buffer guide post 140 is made of a rigid material. When the outer diameter of the flow-limiting buffer is larger than the inner diameter of the second flow guide tube 130, and the flow-limiting buffer guide post 140 is inserted into the second flow guide tube 130 through its port, the second flow guide tube 130 is radially expanded to increase the friction between the outer wall of the flow-limiting buffer guide post 140 and the inner wall of the second flow guide tube 130. This ensures that the flow-limiting buffer guide post 140 can be fixed in an accurate position within the second flow guide tube 130, preventing its position from changing due to liquid flow within the second flow guide tube 130 and affecting the flow-limiting effect.

The beauty device handle 100 is connected to the main unit via one or more guide tubes for conveying liquid or gas. The main unit contains a liquid storage bottle and a circulation pump 212. The liquid storage bottle 211 includes one or more units. The liquid storage bottle 211 is used to store water or other required liquids. The liquid storage bottle 211 is connected to the beauty device handle 100 via a guide tube, and the circulation pump 212 causes the liquid in the liquid storage bottle 211 to flow into the guide tube and out from the handle's round head 112. A first guide tube 120 is connected to the circulation pump 212 and the liquid storage bottle. The flow regulating valve 213 is installed on the main unit, located between the first guide tube 120 and the liquid storage bottle, and is used to regulate the flow rate of the first guide tube 120.
[0048] In some embodiments, the number of guide tubes can be one or more. For example... Figure 1 As shown, when there are multiple guide tubes, their upper ends are arranged side-by-side within the installation space 111, and the lower end of the outer casing 110 can accommodate the insertion of multiple guide tubes. The upper end of the outer casing 110 includes multiple guide holes 1121, each corresponding to a guide tube. Each guide tube is fixedly connected to a guide hole 1121 via a quick-connect air nozzle 150. Flow-limiting buffer guide posts 140 can be installed inside some or all of the guide tubes, and the inner diameters of each guide tube can be the same or different. Each flow-limiting buffer guide post 140 installed inside a guide tube is adapted to the corresponding guide tube.
[0049] In some embodiments, the outer wall of the main unit is also provided with a card slot, the card slot including a card groove and card plates located on both sides of the card groove, and the outer periphery of the upper end of the beauty device handle 100 is provided with an outwardly protruding card protrusion, the beauty device handle 100 can be inserted into the card groove, and the lower end of the card protrusion abuts against the upper end of the card plate so that the beauty device handle 100 can be stored in the outer wall of the main unit.
[0050] In some embodiments, the microbubble beauty device also includes a pressure regulating valve 214. When there are multiple guide tubes and some of the guide tubes are used to transport gas, the pressure regulating valve 214 is provided in the main unit to connect to the guide tubes and is used to regulate the pressure of the water flow or air flow in the guide tubes.
