[0044] The following further elaborates on the detailed implementation manners of the present invention with reference to the accompanying drawings.

[0045] As Figures 1 - 6 shown, a powder dispensing container includes: an upper cover 1, a control assembly, a powder placing member 3 and a powder sealing member 4, wherein the control assembly is arranged on the upper cover 1. Meanwhile, the powder placing member 3 is used for placing powder, and the powder placing member 3 is arranged at the bottom of the upper cover 1, and a closed chamber is formed between the powder placing member 3 and the upper cover 1, and at least one powder outlet 32 and comb teeth 31 are arranged at the bottom of the powder placing member 3.

[0046] Moreover, the powder sealing member 4 is movably arranged in the chamber, that is, movably arranged between the upper cover 1 and the powder placing member 3, and a blocking part 41 for blocking the powder outlet 32 is arranged at the bottom of the powder sealing member 4, and the powder sealing member 4 is connected to the control assembly and moves upward under the drive of the control assembly.

[0047] In this application, by combining the powder container and the comb, during actual use, the user first places the whole on the hair and applies pressure with the hand or in other ways to the control component, thereby driving the powder-sealing member 4 to move upward, further causing the blocking portion 41 to leave the powder outlet 32 and powder to come out. Thus, the powder coming out directly contacts the hair without powder flying. Secondly, the user manually moves the powder-placement member 3 to drive the comb teeth 31 to contact the hair and then evenly distribute the powder. Compared with a powder puff, the comb teeth 31 can better contact the hair and achieve a better powder-distribution effect.

[0048] For a better sealing effect, a second sealing member such as an O-ring is provided between the blocking portion 41 and the powder outlet 32, or the blocking portion 41 and the powder outlet 32 are in interference fit.

[0049] Moreover, the number of powder outlets 32 can be 1 - 199, and the diameter of the powder outlet 32 can be 0.3 - 3 mm. The specific number and aperture size can be set according to the physical form and chemical properties of the internal material (such as the hair powder).

[0050] Such as Figure 2 、 Figure 4 and Figure 5 As shown in

[0051] During actual use, due to the setting of the tapered block 411 and the shape of the inner wall of the powder outlet 32 matching the outer surface of the tapered block 411, that is, the inner wall of the powder outlet 32 is an inclined surface, it plays a guiding role. Moreover, compared with a vertical surface, the gap between the inclined surfaces is larger, so more powder comes out and the movement is smoother.

[0052] At the same time, the number of blocking portions 41 is set according to actual needs and corresponds to the number of powder outlets 32. The three shown in the attached drawings have the following specific structure: First, there are three powder outlets 32, and there are three blocking portions 41 corresponding to the powder outlets 32 at the bottom of the powder-sealing member 4. One is in the middle at the bottom of the blocking portion 41, and the other two are at both ends on one side of the bottom of the blocking portion 41.

[0053] During actual use, by adapting the powder outlets 32 and the blocking portions 41 at different positions and in multiple numbers, the powder-outlet range can be expanded, and thus powder can be applied to different parts of the hair and different parts of the same hair.

[0054] Such as Figure 2 and Figure 4As shown, since each component needs to be reset after use, first, an elastic member II 7 is provided between the upper cover 1 and the powder sealing member 4. Through the elasticity of the elastic member II 7, the upwardly displaced powder sealing member 4 is reset and drives the control assembly to reset. The elastic member II 7 can be an elastic fitting such as a spring.

[0055] As Figures 2 - 4 shown, the structure of the control assembly is as follows: First, the control assembly includes a button 2 and a linkage member 5. The linkage member 5 is rotatably arranged on the powder placing member 3, and both ends of the linkage member 5 are respectively connected to the button 2 and the powder sealing member 4. By pressing the button 2, the linkage member 5 rotates and drives the powder sealing member 4 to move upward.

[0056] Therefore, during actual use, the user first places the whole on the hair. By pressing the button 2, the linkage member 5 rotates and drives the powder sealing member 4 to move upward. The rotation of the linkage member 5 is such that the end of the linkage member 5 connected to the button 2 moves downward, and the end of the linkage member 5 connected to the powder sealing member 4 moves upward. And through the upward movement of the powder sealing member 4, the blocking portion 41 leaves the powder outlet 32 and powder is discharged.

[0057] And corresponding to the reset structure of the powder sealing member 4, since the reset of the control assembly is driven by the powder sealing member 4, the reset principle of the linkage member 5 and the button 2 is also driven by the reset of the powder sealing member 4. When resetting for the first time, no force is applied to the button 2. At this time, the powder sealing member 4 moves downward due to the elasticity of the elastic member II 7 and drives the linkage member 5 to rotate, thereby resetting the button 2. The rotation of the linkage member 5 is such that the end of the linkage member 5 connected to the powder sealing member 4 moves downward, and the end of the linkage member 5 connected to the button 2 moves upward.

[0058] At the same time, in order to make the button 2 reset better, a placement groove 11 is provided on one side of the upper cover 1, and an installation hole 111 is provided at the bottom of the placement groove 11. The button 2 is located in the placement groove 11, and an elastic member I 6 is provided between the button 2 and the bottom of the placement groove 11. One end of the button 2 passes through the installation hole 111 and is connected to the linkage member 5. Through the elasticity of the elastic member I 6, the pressed button 2 is reset. The elastic member I 6 can be an elastic fitting such as a spring.

[0059] So even if the button 2 is not fully reset due to being pushed by the linkage member 5, it can be better reset through the elastic member I 6. Of course, the elastic member I 6 can also cooperate with other reset structures of the powder sealing member 4, and at the same time, the elastic member II 7 can also cooperate with other reset structures of the button 2.

[0060] The installation structure of the elastic member I 6 as a spring is as follows: First, the bottom of the button 2 is a connecting rod 21, and the elastic member I 6 is sleeved on the outside of the connecting rod 21. And in order to prevent the button 2 from disengaging from the installation hole 111 when resetting, a convex edge 211 is also provided on the outside of the connecting rod 21, and the convex edge 211 abuts against the circumferential side of the linkage member 5 close to the installation hole 111, thereby achieving limitation.

[0061] Moreover, for a better sealing effect, a first seal 10 such as a sealing ring is provided between the connecting rod 21 and the mounting hole 111.

[0062] As Figure 2 、 Figure 4 and Figure 5 As shown in

[0063] At the same time, a first rotating shaft 51 is provided on both sides of the linkage member 5. Therefore, during actual use, one end of the linkage member 5 is located in the first card slot 421, and the first rotating shaft 51 is located in the connecting slot 422 and rotates within the connecting slot 422.

[0064] Therefore, during actual use, through the connection of the first card slot 421 and the connecting slot 422 to the linkage member 5, the connection is made more stable and the linkage member 5 is limited in multiple directions.

[0065] As Figure 2 、 Figure 4 and Figure 5 As shown in

[0066] As Figure 2 、 Figure 4 and Figure 5 As shown in

[0067] At the same time, a second rotating shaft 52 is provided on both sides of the linkage member 5. The linkage member 5 is located in the second card slot 331, and the second rotating shaft 52 passes through the opening 333 and is located in the through hole 332, and the second rotating shaft 52 rotates within the through hole 332.

[0068] Therefore, during actual use, through the connection of the second card slot 331 and the through hole 332 to the linkage member 5, the connection is made more stable and the linkage member 5 is limited in multiple directions.

[0069] Secondly, in order to better limit the linkage member 5, the linkage member 5 includes a first connecting section 53 and a second connecting section 54. The thickness dimension of the first connecting section 53 is smaller than that of the second connecting section 54. The first connecting section 53 is located in the second card slot 331, and two rotating shafts 52 are arranged on both sides of the first connecting section 53.

[0070] Meanwhile, a step surface 55 is arranged between the first connecting section 53 and the second connecting section 54, and the linkage member 5 is limited by the cooperation between the step surface 55 and the outer wall of the installation part 33. Moreover, to avoid right-angle interference, the top outer wall of the installation part 33 is formed into an arc surface.

[0071] As Figure 2 、 Figure 4 and Figure 5 shown, the structure between the powder sealing member 4 and the powder placing member 3 is as follows: First, the powder sealing member 4 is provided with a connection hole, and a connection column 34 is arranged at the top of the powder placing member 3. The connection column 34 is located in the connection hole, and the powder sealing member 4 moves up and down along the connection column 34.

[0072] Meanwhile, corresponding to this structure, when the second elastic member 7 is a spring, its installation structure is as follows: First, the powder sealing member 4 is provided with a connection platform 43, and the connection platform 43 is provided with a groove. There is a connection hole at the bottom of the groove, and the connection column 34 passes through the connection hole and protrudes. At the same time, the upper cover 1 is provided with an installation platform 14 with a groove, and the second elastic member 7 is sleeved outside the connection column 34, and both ends of the second elastic member 7 are respectively located in the installation platform 14 and the connection platform 43.

[0073] As Figure 2 、 Figure 4 and Figure 5 shown, the structure between the upper cover 1 and the powder placing member 3 is as follows: First, a first convex plate 35 is arranged at the top of the powder placing member 3, and a protruding portion 351 is arranged outside the first convex plate 35. The first convex plate 35 is located inside the upper cover 1, and a groove 12 is provided on the inner wall of the upper cover 1 corresponding to the protruding portion 351.

[0074] Therefore, during the actual use process, the first convex plate 35 is located inside the upper cover 1, and the protruding portion 351 and the groove 12 are adapted to each other to achieve connection.

[0075] As Figures 2 - 4 shown, the powder feeding structure is as follows: First, a powder feeding port 13 is provided at the top of the upper cover 1, a sealing plug 8 is arranged in the powder feeding port 13, and the powder sealing member 4 is provided with a plurality of powder leakage holes 44.

[0076] Therefore, during the actual use process, when powder needs to be put in, the sealing plug 8 is taken out and powder is poured in through the powder feeding port 13. After the powder is put in, the sealing plug 8 is placed in the powder feeding port 13 for sealing.

[0077] Among them, the obstruction of the powder-sealing member 4 to the falling of the powder is avoided. Therefore, a powder leakage hole 44 is provided in the powder-sealing member 4. Thus, when the powder is placed, the powder will pass through the powder leakage hole 44 and fall onto the powder-placement member 3.

[0078] As Figures 1 - 2 shown, a base 9 is provided at the bottom of the powder-placement member 3, and the base 9 covers one side of the comb teeth 31.

[0079] Therefore, in the actual use process, through the setting of the base 9, the comb teeth 31 are protected. At the same time, when it is not in use and the button 2 is touched, the powder will fall onto the base 9 and will not spill on the desktop.

[0080] The structure between the base 9 and the powder-placement member 3 is as follows: First, a third card slot is provided at the bottom of the powder-placement member 3, and a second convex plate 91 is provided at the top of the base 9, and the second convex plate 91 is located in the third card slot to achieve connection.

[0081] As Figure 2 shown, the comb teeth 31 as a whole can be integrally formed or detachable. Thus, in the actual use process, since the comb teeth 31 are detachably provided at the bottom of the powder-placement member 3, the comb teeth 31 are replaceable. For example, they can be replaced when damaged. At the same time, the part of the powder-placement member 3 excluding the comb teeth 31 can be reused, which not only reduces the cost but also avoids excessive use of plastic.

[0082] At the same time, the bottom of the powder-placement member 3 is an arc surface and protrudes upward, so it is more similar to the shape of the head, and thus can better contact the hair. Moreover, the lengths of both sides of the comb teeth 31 are shorter than the middle length, so they can better cooperate with the base 9.

[0083] The above shows and describes the basic principles, main features and advantages of the present invention. At the same time, the present invention is not limited by the above embodiments. Therefore, without departing from the principles and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
