[0047] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will detail this application with reference to the drawings and in conjunction with the embodiments.

[0048] As Figures 1-12 shown, this application relates to a dispensing mechanism and a powder spraying device. As Figures 8-10 shown, the dispensing mechanism includes: a container 10; the container 10 refers to an appliance with a containing function, which can achieve a good powder containing effect, thereby providing guarantee for subsequent directional powder spraying. Preferably, the shape of the container 10 is cylindrical, which can achieve a good powder containing effect and at the same time can achieve a good matching effect with other components.

[0049] The accommodating member 20 is covered on the top of the container 10. By covering the accommodating member 20 on the top of the container 10, a good covering effect can be achieved, thereby preventing the powder from leaking and further affecting the use effect. At the same time, by providing the accommodating member 20, after the device is inverted, the powder can move into the accommodating member 20, thereby achieving the effect of directional movement of the powder.

[0050] The powder spraying extension member 30 is disposed through the center of the accommodating member 20, and at least a part of its bottom extends close to the bottom of the container 10. By providing the powder spraying extension member 30, a channel for the powder to enter and exit can be formed. At the same time, extending the powder spraying extension member 30 close to the bottom of the container 10 can achieve a good powder receiving effect, thereby providing a basis for subsequent powder output.

[0051] Furthermore, the diameter of the powder spraying extension member 30 is smaller than the diameter of the accommodating member 20. This can achieve the effect of providing a reserved space for subsequent powder accommodation.

[0052] At least two powder outlets 40 are opened on the powder spraying extension member 30 on one side close to the bottom of the container 10 and are evenly arranged along the circumferential direction of the powder spraying extension member 30. By evenly arranging at least two powder outlets 40 on one side close to the bottom of the powder spraying extension member 30 and along its circumferential direction, the powder can enter the powder spraying extension member 30 from multiple angles, thereby achieving the effect of flexible use.

[0053] Among them, by evenly distributing at least two powder outlets 40 on one side close to the bottom of the powder spraying extension member 30, the non-directional flow of the powder in the powder spraying extension member 30 is controlled. By evenly distributing at least two powder outlets 40 in the circumferential direction of the powder spraying extension member 30, a non-directional pouring function can be achieved, thereby achieving the effect of convenient use.

[0054] From the above description, it can be seen that the following technical effects are achieved in this application:

[0055] In the embodiment of this application, by adopting the method of presetting at least two powder outlets 40, and evenly distributing at least two powder outlets 40 on one side close to the bottom of the powder spraying extension member 30 to control the non-directional flow of the powder in the powder spraying extension member 30, the purpose of non-directional flow of the powder is achieved, thereby achieving the technical effects of quantitative and stable powder output, and further solving the technical problems of the traditional powder device having a single structure. Although it can partially achieve quantitative powder output, the powder output effect is not good, and the powder is easy to scatter at the outlet, resulting in waste or pollution; and, due to the fluidity of the powder and the unevenness of the particle size, the output amount is also unstable, affecting the final use effect.

[0056] Further, an inner wall of the container 10, an inner wall of the accommodating member 20, and an outer wall of the powder spraying extension member 30 enclose a powder spraying pre-set cavity 50. It can be understood that by enclosing the powder spraying pre-set cavity 50 with the inner wall of the container 10, the inner wall of the accommodating member 20, and the outer wall of the powder spraying extension member 30, when the device is inverted, the powder or crystals originally in the bottle body 70 can be transferred to the powder spraying pre-set cavity 50, thereby ensuring subsequent powder spraying. At the same time, it can also achieve the function of preliminary screening.

[0057] Further, the container 10 includes: a cavity 101, a top of the cavity 101 is provided with an inclined cone portion 102 with a diameter increasing from bottom to top, a top of the inclined cone portion 102 is provided with a tubular portion 103, and a top of the tubular portion 103 is provided with a first bending portion 104. It can be understood that by providing the cavity 101, a good accommodating effect for the powder to be sprayed can be achieved; at the same time, by providing the inclined cone portion 102 above the cavity 101, a good powder guiding effect can be achieved, thereby ensuring the powder to enter the powder spraying pre-set cavity 50; and by providing the tubular portion 103 on the inclined cone portion 102 and the first bending portion 104 at the top of the tubular portion 103, a good assembly effect with other components can be achieved.

[0058] Preferably, an angle of the inclined cone portion 102 is 45 - 65 degrees. By adopting the above range, it can ensure that the powder smoothly enters the powder spraying pre-set cavity 50.

[0059] Further, the inclined cone portion 102 is uniformly provided with a plurality of feed ports 1021 for the powder to enter the powder spraying pre-set cavity 50 along a circumferential direction. It can be understood that by uniformly providing a plurality of feed ports 1021 on the inclined cone portion 102, the effect of allowing the powder to enter the powder spraying pre-set cavity 50 from multiple angles and multiple positions can be achieved, thereby ensuring a good powder transfer effect.

[0060] Preferably, the number of the feed ports 1021 is six. It can ensure good structural strength while ensuring good feeding. Of course, the number of the feed ports 1021 can be increased or decreased according to actual usage requirements and is not limited in this application.

[0061] Further, a top of the accommodating member 20 is provided with a second bending portion 201 extending towards the container 10 and abutted against the first bending portion 104, and a gap 60 is provided between an extending portion 202 of the second bending portion 201 and an outer wall of the tubular portion 103. It can be understood that by providing the second bending portion 201 and reserving the assembly gap 60, a good cooperation effect between components can be achieved, thereby ensuring a stable assembly effect.

[0062] Further, the diameter of the tubular portion 103 is greater than or equal to the diameter of the accommodating member 20. It can be understood that by adopting the diameter of the tubular portion 103 to be greater than or equal to the diameter of the accommodating member 20, the situation of powder accumulation in the accommodating member 20 can be prevented, because when the powder is transferred from the accommodating member 20 to the cavity 101 of the container 10, the tubular portion 103 will not block the powder, thus ensuring that the powder smoothly enters the cavity 101.

[0063] Preferably, the diameter of the tubular portion 103 matches the diameter of the accommodating member 20; the effect that the powder can enter and exit the accommodating member 20 without being blocked can be achieved.

[0064] As Figures 11-12 shown, the number of powder outlets 40 is three. It can be understood that by using three powder outlets 40, on the premise of ensuring quantitative powder output, sufficient structural strength can also be ensured, thereby achieving the effect of extending the service life.

[0065] Further, a cylindrical structure 110 is provided at the bottom of the powder outlet 40, and the cylindrical structure 110 is connected to the powder spraying extension member 30 through at least two connecting members 120; at least two connecting members 120 are arranged between two powder outlets 40. It can be understood that by providing the cylindrical structure 110, the effect of improving the structural stability can be achieved; at the same time, by connecting the powder spraying extension member 30 and the cylindrical structure 110 through at least two connecting members 120, a good connection effect can be achieved.

[0066] Preferably, at least two connecting members 120 are evenly arranged between the powder outlets 40, which can ensure good structural strength and at the same time achieve the effect of evenly arranging the powder outlets 40, thereby ensuring the effect of non-directional powder flow.

[0067] Preferably, the number of the connecting members 120 matches the number of the powder outlets 40. A good connection effect can be achieved.

[0068] Further, the diameter of the cylindrical structure 110 is not greater than the diameter of the powder spraying extension member 30. It can be understood that by setting the diameter of the cylindrical structure 110 not to be greater than the diameter of the powder spraying extension member 30, the effect of adjusting the powder input and output amount can also be achieved. As the diameter of the cylindrical structure 110 decreases, the powder output amount will also decrease, so that according to the actual use requirements, the corresponding diameter of the cylindrical structure 110 can be adopted to obtain the required powder output amount.

[0069] Further, the shape of the powder outlet 40 is a straight tubular shape or an inclined tubular shape. It can be understood that by adopting a straight tubular shape or an inclined tubular shape, the effect of having multiple shapes to choose from can be achieved, so as to flexibly meet various use requirements.

[0070] Specifically, when the shape of the powder outlet 40 is a straight tube, a good quantitative powder discharging effect can be achieved. At the same time, the shape of the powder outlet 40 opened thereon is a rectangular orifice structure. Preferably, the rectangular orifice structure is a rectangle, and the long side of the rectangle is in the vertical direction. A good quantitative powder feeding effect can be achieved.

[0071] Preferably, the height of the rectangular orifice structure at the short side of its top is not greater than the height of the bottom edge of the feed port 1021. This can prevent the powder from directly entering the rectangular orifice structure from the feed port 1021.

[0072] When the shape of the powder outlet 40 is an inclined tube, the effect of adjusting the powder feeding amount can be achieved, so that the effect of multiple supply amounts being selectable can be achieved.

[0073] Preferably, the inclined tube can have a diameter that gradually increases or gradually decreases from top to bottom. Different powder discharging effects can be obtained.

[0074] Furthermore, the shape of the accommodating member 20 is cylindrical, elliptical or conical. It can be understood that the effect of multiple shapes being selectable can be achieved, so as to achieve the effect of flexible use.

[0075] As Figures 1-5 shown, the present application also relates to a powder spraying device, including the above-mentioned dispensing mechanism;

[0076] It also includes: a bottle body 70, the bottle body 70 is hollow, a boss 80 is provided at the top of the bottle body 70, a bottle mouth 90 connected to the inner wall of the accommodating member 20 is provided at the top of the boss 80, and a bottle cap 100 is covered on the boss 80. It can be understood that by providing a hollow bottle body 70, the effect of filling a large amount of powder or crystals can be achieved; at the same time, by respectively providing a boss 80 and a bottle mouth 90, the effect of good cooperation between components can be achieved, so as to ensure a stable assembly effect. Preferably, the boss 80 is in the shape of a cube. A good clamping and fixing effect can be achieved.

[0077] As Figure 6 shown, the bottle mouth 90 is arranged in the gap 60, and at least a first annular recess 901 is provided on its outer surface, and the first annular recess 901 is engaged with a first annular protrusion 2021 provided on the inner wall of the extension part 202. It can be understood that a good limiting and engaging effect can be achieved; at the same time, the effect of easy disassembly and assembly can also be achieved, so as to achieve the effect of easy replacement and cleaning of the powder.

[0078] As Figures 6-7As shown, at least two opposite limiting convex parts 801 are provided on the outer surface of the boss 80, and the limiting convex parts 801 are engaged with the limiting concave parts 1001 formed on the inner wall of the bottle cap 100. It can be understood that a good capping effect between the bottle body 70 and the cap body can be achieved, thus realizing the effect of facilitating the opening and closing of the bottle cap 100.

[0079] Furthermore, a limiting part 1002 that matches the top of the accommodating part 20 and is used to limit one end of the accommodating part 20 is provided on the inner surface of the top of the bottle cap 100. It can be understood that by providing the limiting part 1002 on the inner wall of the top of the bottle cap 100, a good limiting and fixing effect on the top of the accommodating part 20 can be achieved, thereby ensuring its stable state.

[0080] Furthermore, an initial powder accommodating cavity is formed by enclosing the inner wall of the bottle body 70 and the outer wall of the container 10. By enclosing a large accommodating cavity with the inner wall of the bottle body 70 and the outer wall of the container 10, it is possible to pre-fill the powder or other crystals in the initial powder accommodating cavity, so that when directional powder spraying is required, the effect of providing powder at any time can be achieved.

[0081] Furthermore, the bottle mouth 90 is in interference fit with the tubular part 103. The effect of ensuring a tight assembly can be achieved, thereby avoiding the occurrence of powder leakage.

[0082] Furthermore, the length of the bottle mouth 90 matches the length of the tubular part 103. A good assembly effect can be ensured, and at the same time, the situation of powder blockage can be avoided.
