[0045] As Figures 1-9 shown, this application relates to a powder spraying assembly and a powder spraying device with a current limiting member. As Figures 7-9 shown, the powder spraying assembly with a current limiting member includes: a container 10; the container 10 refers to an instrument with a containing function, which can achieve a good powder containing effect, thereby 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 cooperation effect with other components.

[0046] 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.

[0047] 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.

[0048] Furthermore, the diameter of the powder spraying extension member 30 is smaller than the diameter of the accommodating member 20. It can provide a reserved space for subsequent powder accommodation.

[0049] The flow limiting member 120 is disposed at the bottom of the powder spraying extension member 30, and one end of the flow limiting member 120 away from the powder spraying extension member 30 inclines towards the inner wall of the container 10. By providing the flow limiting member 120, the effect of blocking the powder can be achieved.

[0050] Preferably, the flow limiting member 120 is an arc-shaped baffle; a good material blocking effect can be achieved. Of course, it can also be in a shape similar to a retaining wall, etc., and is not limited in this application.

[0051] Preferably, the shape of the flow limiting member 120 is trumpet-shaped. It can ensure a good material blocking effect and avoid blockage.

[0052] Among them, by directionally adding the flow limiting member 120 at the bottom of the powder spraying extension member 30 to increase the quantitative flow of the powder into the powder spraying extension member 30. When pouring out the powder, part of the powder can be blocked from entering the powder spraying extension member 30, thereby increasing the amount of powder poured out.

[0053] From the above description, it can be seen that the following technical effects are achieved in this application:

[0054] In the embodiment of this application, by adopting the method of adding the flow limiting member 120, by directionally adding the flow limiting member 120 at the bottom of the powder spraying extension member 30 to increase the quantitative flow of the powder into the powder spraying extension member 30, the purpose of increasing the amount of powder poured out is achieved, thereby achieving the technical effects of improving the pouring efficiency and stability, and further solving the technical problems that the structure of the traditional powder device is single, although it can partially achieve the quantitative output of the powder, but the powder output amount is not good, resulting in inability to meet the actual use; 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.

[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 to form 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, thus providing guarantee for subsequent powder spraying. At the same time, it can also realize the function of preliminary screening.

[0056] Further, the container 10 includes: a cavity 101, a tapered portion 102 with a diameter increasing from bottom to top is arranged at the top of the cavity 101, a tubular portion 103 is arranged at the top of the tapered portion 102, and a first bending portion 104 is arranged at the top of the tubular portion 103. It can be understood that by providing the cavity 101, a good accommodating effect for the powder to be sprayed can be realized; at the same time, by providing the tapered portion 102 above the cavity 101, a good powder guiding effect can be realized, thus providing guarantee for the powder to enter the powder spraying pre-set cavity 50; and by providing the tubular portion 103 on the tapered 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 realized.

[0057] Preferably, the angle of the tapered 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, a plurality of feed ports 1021 for the powder to enter the powder spraying pre-set cavity 50 are evenly arranged on the tapered portion 102 along the circumferential direction. It can be understood that by evenly arranging a plurality of feed ports 1021 on the tapered 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 realized, thus ensuring a good powder transfer effect.

[0059] 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.

[0060] Further, a second bending portion 201 extending towards the container 10 and abuting against the first bending portion 104 is arranged at the top of the accommodating member 20, and a gap 60 is arranged between an extension portion 202 of the second bending portion 201 and the 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 realized, thus ensuring a stable assembly effect.

[0061] Furthermore, 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 of powder accumulation 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, thus 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] Preferably, the angle range between the flow limiting member 120 and the vertical center line is 15° - 20°. It can be understood that by setting the angle between the flow limiting member 120 and the vertical center line within the above range, a good powder blocking effect can be ensured; at the same time, the influence of the powder entering the bottom of the container 10 from the powder spraying pre - set cavity 50 can also be reduced.

[0064] Furthermore, it further includes: a plurality of quantitative pouring outlets 40, which are opened on the powder spraying extension member 30 near one side of the bottom of the container 10 and are uniformly arranged along the circumferential direction of the powder spraying extension member 30; a flow limiting member 120 is obliquely arranged at the top of the quantitative pouring outlet 40 and at the junction with the powder spraying extension member 30;

[0066] Specifically, a plurality of quantitative pouring outlets 40 are opened on the powder spraying extension member 30 near one side of the bottom of the container 10 and are uniformly arranged along the circumferential direction of the powder spraying extension member 30; by uniformly arranging a plurality of quantitative pouring outlets 40 along the circumferential direction on the powder spraying extension member 30 near its bottom side, the powder can enter the powder spraying extension member 30 from multiple angles, thus achieving the effect of flexible use.

[0067] By respectively and correspondingly obliquely arranging a plurality of flow limiting members 120 at the tops of the plurality of quantitative pouring outlets 40, the quantitative flow of the powder entering the powder spraying extension member 30 is increased; when pouring, the powder will increase, thereby increasing the amount of powder poured out.

[0068] It should be noted that by setting the quantitative pouring outlets 40 with different specifications; the effect of adjusting the amount of powder poured out can be achieved.

[0069] Further, the number of the plurality of quantitative discharge ports 40 and the number of the plurality of flow limiters 120 are three, and they are arranged in one-to-one correspondence.

[0071] Preferably, at least two connecting members 130 are evenly arranged between the quantitative discharge ports 40, which can ensure good structural strength, and at the same time, it can also achieve the effect of evenly arranging the quantitative discharge ports 40, so as to ensure the effect of non-directional powder flow.

[0072] Preferably, the number of the connecting members 130 matches the number of the quantitative discharge ports 40. A good connection effect can be achieved.

[0073] Further, the diameter of the cylindrical structure 110 is not greater than the diameter of the powder spraying extension 30. It can be understood that by setting the diameter of the cylindrical structure 110 to be smaller than the diameter of the powder spraying extension 30, the effect of adjusting the powder inlet and outlet amount can also be achieved. As the diameter of the cylindrical structure 110 decreases, the powder output amount will also decrease, so that the corresponding diameter of the cylindrical structure 110 can be adopted according to the actual use requirements, and then the required powder output amount can be obtained.

[0074] Further, the shape of the quantitative discharge port 40 is an inclined tubular shape. It can be understood that when the shape of the quantitative discharge port 40 is an inclined tubular shape, the effect of adjusting the powder feeding amount can be achieved, so that the effect of multiple supply amounts can be selected.

[0075] Preferably, the inclined tubular shape can be gradually decreasing in diameter from top to bottom. Different powder output effects can be obtained.

[0076] Further, the shape of the accommodating member 20 is cylindrical, elliptical or conical. It can be understood that the effect of multiple shapes available for selection can be achieved, so as to achieve the effect of flexible use.
