[0042] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0043] As Figures 1-9 shown, the present application relates to a directional powder spraying assembly and a powder spraying device. As Figures 7-9 shown, the directional powder spraying assembly includes: a container 10; the container 10 refers to an appliance with a containing function, which can achieve a good powder containing effect, thus providing a 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 also achieve a good matching effect with other components.

[0044] A containing member 20, covering the top of the container 10; by covering the top of the container 10 with the containing member 20, 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 containing member 20, it can be realized that after the device is inverted, the powder moves into the containing member 20, thus realizing the effect of directional movement of the powder.

[0045] A powder spraying extension member 30, penetrating through the center of the containing member 20, and at least 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, thus providing a basis for subsequent powder output.

[0046] Further, the diameter of the powder spraying extension member 30 is smaller than the diameter of the accommodating member 20, which can provide a reserved space for the subsequent accommodation of the powder.

[0047] Wherein, a notch 40 is provided at the bottom of the powder spraying extension member 30, and the notch 40 is arranged along the length direction of the powder spraying extension member 30 to control the directional flow of the powder at the notch 40.

[0048] Specifically, by providing a notch 40 on the powder spraying extension member 30 near the bottom side of the container 10 and arranging it along the length direction of the powder spraying extension member 30, a good directional pouring effect can be achieved, so as to better meet the usage requirements.

[0049] The powder flow in the powder spraying extension member 30 can also be controlled by rotating the notch 40 to several preset specified positions. By providing the notch 40 and rotating it to different positions, the effects of controlling the powder inlet and outlet can be achieved. At the same time, the effect of controlling the powder inlet and outlet amount can also be achieved.

[0050] For example: when the notch 40 is rotated to the state where the powder can be accommodated (upright), at this time, the powder accumulates at the notch 40, so that the powder can be smoothly poured out from the powder spraying extension member 30, and the amount of powder poured out at this time is the largest.

[0051] When the notch 40 is rotated to the state where the powder cannot be accommodated (inverted), at this time, the powder cannot accumulate at the notch 40, so that no powder can be poured out from the powder spraying extension member 30, and the amount of powder poured out at this time is zero.

[0052] When the notch 40 is rotated to the state where the powder can be accommodated (offset) and is not in the completely upright state, at this time, the powder can also accumulate at the notch 40, so that the powder can be smoothly poured out from the powder spraying extension member 30. However, the amount of powder poured out at this time is relatively small.

[0053] From the above description, it can be seen that the present application achieves the following technical effects:

[0054] In the embodiment of the present application, by adopting the method of presetting the notch 40, a notch 40 is provided at the bottom of the powder spraying extension member 30, and the notch 40 is arranged along the length direction of the powder spraying extension member 30 to control the directional flow of the powder at the notch 40, so as to achieve the purpose of directional pouring of the powder, thereby realizing the technical effect of controlling the powder inlet and outlet, and further solving the technical problem that the existing powder device has a single structure and cannot achieve the function of directional powder output, resulting in great limitations in the actual use process.

[0055] 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 by 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.

[0056] 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 enters 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.

[0057] 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.

[0058] 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, and a bottom height of the feed port 1021 is not less than a top height of the notch 40. It can be understood that by uniformly providing a plurality of feed ports 1021 on the inclined cone portion 102, a powder spraying pre-set cavity 50 can be achieved with the powder entering from multiple angles and multiple positions, thereby ensuring a good powder transfer effect; at the same time, an upper edge of the notch 40 is not higher than a lower edge of the feed port 1021. It can prevent the powder from directly entering the notch 40 when inverted.

[0059] Preferably, the number of the feed ports 1021 is six. It can ensure a good structural strength while ensuring good feeding. Of course, the number of the feed ports 1021 can be increased or decreased according to actual use requirements, and is not limited in this application.

[0060] 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 matching effect between components can be achieved, thereby ensuring a stable assembly effect.

[0061] 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 a diameter of the tubular portion 103 that is greater than or equal to the diameter of the accommodating member 20, the situation where powder accumulates in the accommodating member 20 can be prevented, because when the powder is transferred from the accommodating member 20 into the cavity 101 of the container 10, the tubular portion 103 will not block the powder, thereby ensuring that the powder smoothly enters the cavity 101.

[0062] 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.

[0063] Further, the shape of the notch 40 is semi-cylindrical. It can be understood that by adopting a semi-cylindrical shape, a good powder accommodating effect can be achieved, thereby ensuring a good powder spraying effect from the powder spraying extension member 30. Of course, the notch dividing line of the notch 40 can be located at the vertical center line of the powder spraying extension member 30, or offset on both sides of the vertical center line, and can be cut according to actual usage requirements, and is not limited in this application.

[0064] Further, the shape of the accommodating member 20 is cylindrical, elliptical or conical. It can be understood that the effect of having multiple shapes available for selection can be achieved, thereby achieving the effect of flexible use.

[0065] As Figure 4 shown, an indication mark 110 for guiding the powder spraying direction is provided at the top of the accommodating member 20, and the direction of the indication mark 110 is opposite to the direction of the notch 40. It can be understood that by providing the indication mark 110 at the top of the accommodating member 20, a good guiding mark effect can be achieved, thereby ensuring a good powder spraying guiding effect. Preferably, the indication mark 110 can be an arrow; a good guiding effect can be achieved. Of course, it can also be in other forms, such as: a fan-shaped area, but in this case, the position setting of the fan-shaped area needs to match the shape of the notch 40.

[0066] As Figures 1-3 shown, the present application also relates to a powder spraying device, including the above-mentioned directional powder spraying assembly;

[0067] It further includes: a bottle body 70, which 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. 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, a good matching effect between components can be achieved, thus ensuring a stable assembly effect. Preferably, the boss 80 is in the shape of a cube, which can achieve a good clamping and fixing effect.

[0068] As Figure 5 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. 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 being convenient for disassembly and assembly can also be achieved, thus realizing the effect of being easy to replace and clean the powder.

[0069] As Figure 4 and 6 shown, at least two opposite limiting protrusions 801 are provided on the outer surface of the boss 80. The limiting protrusions 801 are engaged with limiting recesses 1001 provided on the inner wall of the bottle cap 100. It can be understood that a good covering effect between the bottle body 70 and the cover body can be achieved, thus realizing the effect of being convenient for opening and closing the bottle cap 100.

[0070] Furthermore, a limiting part 1002 that matches the top of the accommodating member 20 and is used to limit one end of the accommodating member 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 member 20 can be achieved, thus ensuring its stable state.

[0071] 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, the powder or other crystals can be pre-filled 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.

[0072] Furthermore, the bottle mouth 90 is in interference fit with the tubular part 103. The effect of ensuring a tight assembly can be achieved, thus avoiding the situation of powder leakage.

[0073] Furthermore, the length of the bottle mouth 90 matches the length of the tubular part 103. The effect of ensuring a good assembly can be achieved. At the same time, the situation of powder blockage can also be avoided.

[0074] The preferred embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present utility model, various equivalent transformations can be made to the technical solutions of the present utility model, and these equivalent transformations all fall within the protection scope of the present utility model.
