If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0031] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0032] The existing powder feeder is mainly composed of a base, a powder barrel, and a powder outlet. The powder is loaded into the powder barrel, the powder outlet is connected to the powder-using equipment, the powder feeder is connected to the air source, and the control switch is turned on, and the powder can be transported to the powder-using equipment through the airflow. However, the powder-using equipment sometimes needs to be replaced with other types of powders midway, and the powder feeder needs to change the powder supply. For example, the powder barrel was previously filled with powder A, and now powder B needs to be used instead, so powder A needs to be cleaned out of the powder barrel and then loaded with powder B. However, if powder A in the powder barrel is not cleaned up, part of powder A will be mixed into the powder B that is loaded later, resulting in a decrease in the purity of the powder.

[0033] Current powder feeders do not have powder cleaning devices. The current cleaning method is to insert the powder outlet into a plastic bag or an empty bottle and discharge the powder through airflow. Under this method, the plastic bag or empty bottle cannot be completely sealed (if the airflow is sealed, there is nowhere to go), and some powder will be discharged into the air with the airflow, which will pollute the air and cause harm to the human body after the powder is inhaled.

[0034] In this regard, the present application proposes a powder feeder and a powder supply device including the same, which performs a first-stage filtration on the powder through a powder collecting bottle 100, and utilizes the weight of the powder itself to cause it to accumulate at the bottom of the powder collecting bottle 100 to complete collection; the powder still remaining in the air flow enters the filter bottle 200 for a second-stage filtration, so that the powder is dissolved in the liquid used for filtration, further purifies the air flow, and reduces the chance of powder diffusing into the external air.

[0035] Reference Figure 1 and Figure 2The powder feeder in the embodiment of the first aspect of the present application includes a powder collecting bottle 100, a filter bottle 200, a first air pipe 300, a second air pipe 400 and a third air pipe 500. The powder collecting bottle 100 is used to perform a first-stage filtration on the airflow and collect powder, the filter bottle 200 is used to perform a second-stage filtration on the airflow, the first air pipe 300 is used to guide the airflow into the powder collecting bottle 100, the second air pipe 400 is used to guide the airflow from the powder collecting bottle 100 into the filter bottle 200, and the third air pipe 500 is used to guide the airflow to be discharged from the filter bottle 200.

[0036] Specifically, the tops of the powder collecting bottle 100 and the filter bottle 200 are each provided with two openings for connecting to the respective air pipes, and the filter bottle 200 is filled with a liquid for filtering. In this embodiment, the liquid is water. It is easy to understand that if the powder and water can react and explode, the liquid can also be replaced with other liquids that can dissolve the powder.

[0037] The first air pipe 300 is inserted into one of the openings of the powder collecting bottle 100, and the first end of the second air pipe 400 is inserted into the other opening of the powder collecting bottle 100. It is worth noting that the first end of the second air pipe 400 is higher than half of the height of the powder collecting bottle, so as to prevent the powder from being discharged from the second air pipe 400 along with the air flow due to the first end of the second air pipe 400 being set too low. The second end of the second air pipe 400 is inserted into one of the openings of the filter bottle 200 and inserted into the liquid for filtration, so that the air flow can directly contact the liquid for filtration after entering the filter bottle 200, and complete the dissolution of the powder in the liquid.

[0038] The third air pipe 500 is inserted into another opening of the filter bottle 200, and its end is higher than the liquid level of the liquid for filtration, thereby preventing the liquid from being discharged from the third air pipe 500 due to the influence of air pressure due to the end of the third air pipe 500 being set too low.

[0039] The working principle of the powder feeder is as follows: the airflow carrying powder flows in from the first air pipe 300, passes through the powder collecting bottle 100, the second air pipe 400, the filter bottle 200 and the third air pipe 500 in sequence, and is discharged from the third air pipe 500. When the airflow enters the powder collecting bottle 100, the powder naturally settles at the bottom of the powder collecting bottle 100 due to its own weight, and most of the powder can be collected. A small amount of powder enters the filter bottle 200 with the airflow and dissolves in the liquid therein, and the airflow after filtration flows out from the third air pipe 500. Since the airflow passes through two stages of filtration of the powder collecting bottle 100 and the filter bottle 200, the powder content therein is relatively small, which can meet the external discharge requirements.

[0040] Furthermore, the end of the first air pipe 300 is higher than half the height of the powder collecting bottle 100, thereby preventing the first air pipe 300 from being inserted into the accumulated powder. The airflow blown out from the first air pipe 300 will lift the powder, which may flow into the second air pipe 400 and cause the powder to flow out.

[0041] Furthermore, the powder collecting bottle 100 includes a powder collecting bottle body 110 and a powder collecting bottle cap 120, and the powder collecting bottle body 110 and the powder collecting bottle cap 120 are threadedly sealed. After unscrewing the powder collecting bottle cap 120, the powder collected in the powder collecting bottle body 110 can be poured out and the powder can be recycled.

[0042] The first air pipe 300 and the second air pipe 400 are both connected to the powder collecting bottle cap 120. Specifically, the first air pipe 300 and the second air pipe 400 are both detachably connected to the powder collecting bottle cap 120, so that the first air pipe 300 and the second air pipe 400 can be removed from the powder collecting bottle cap 120 during subsequent maintenance for separate cleaning and maintenance.

[0043] Furthermore, the filter bottle 200 includes a filter bottle body 210 and a filter bottle cap 220, and the filter bottle body 210 and the filter bottle cap 220 are threadedly sealed. The filter bottle cap 220 can be unscrewed to pour out the liquid in the filter bottle body 210, thereby realizing the replacement of the filtering liquid in the filter bottle 200 and also facilitating the cleaning of the inside of the filter bottle body 210.

[0044] The second air pipe 400 and the third air pipe 500 are both connected to the filter bottle cap 220. Specifically, the second air pipe 400 and the third air pipe 500 are both detachably connected to the filter bottle cap 220, so that the second air pipe 400 and the third air pipe 500 can be removed from the filter bottle cap 220 during subsequent maintenance for separate cleaning and maintenance.

[0045] Furthermore, both the powder collecting bottle 100 and the filter bottle 200 are transparent bottles, so that the user can observe the amount of powder collected in the powder collecting bottle 100 through the powder collecting bottle 100 to determine whether the powder needs to be poured out to make more space; and observe the turbidity of the liquid in the filter bottle 200 to determine whether the filtering liquid needs to be replaced.

[0046] Furthermore, the powder feeder further includes a plurality of joints 600, the first air pipe 300 and the second air pipe 400 are connected to the powder collecting bottle 100 through the joints 600, and the second air pipe 400 and the third air pipe 500 are connected to the filtering bottle 200 through the joints 600. The joints 600 play a role in fixing the air pipes and also play a sealing role to prevent powder from flowing out from the gap between the air pipe and the powder collecting bottle 100 or the filtering bottle 200.

[0047] Reference Figure 3, a powder supply device in an embodiment of the second aspect of the present application comprises a base 700, a powder barrel 800, a solenoid valve 900 and the above-mentioned powder feeder. The powder barrel 800 is used to store powder and is connected to the base 700, and the base 700 is used to control the output of the powder in the powder barrel 800. The solenoid valve 900 comprises an inlet and two outlets, the inlet of the solenoid valve 900 is connected to the base 700, one of the outlets of the solenoid valve 900 is connected to the first air pipe 300, and the other outlet of the solenoid valve 900 is connected to the powder-using device. The solenoid valve 900 can switch the inlet to be connected to one of the outlets, thereby controlling whether the powder in the powder barrel 800 is output to the present powder feeder or to the powder-using device.

[0048] Furthermore, the base 700 is provided with two or more mounting slots for mounting more powder cartridges 800 , and different powder cartridges 800 can be switched through the base 700 for powder supply, thereby reducing the labor burden during powder replacement.

[0049] Furthermore, a plurality of rollers are provided at the bottom of the base 700, so as to facilitate the movement of the base 700 and improve its portability.

[0050] The following is an introduction to the working process of the powder supply equipment:

[0051] S100. When the powder device is working normally, the powder in the powder cartridge 800 is output to the powder device via the base 700 and the solenoid valve 900;

[0052] S200. When the powder supply needs to be interrupted, the base 700 cuts off the powder supply of the powder cartridge 800; at the same time, the solenoid valve 900 is triggered, which cuts off the connection between its inlet and the powder-using device, and the inlet is connected to the powder feeder;

[0053] S300. The powder in the base 700 and the pipe flows with the air flow and enters the powder collecting bottle 100 through the first air pipe 300;

[0054] S400. Most of the powder naturally settles at the bottom of the powder collecting bottle 100 due to its own weight;

[0055] S500. A small portion of the powder continues to flow with the air flow and enters the filter bottle 200 through the second air pipe 400;

[0056] S600. The powder is fully in contact with the liquid in the filter bottle 200 and dissolved in the liquid;

[0057] S700. The airflow after filtering the powder is discharged from the third air pipe 500 to the outside, and the collection and filtering of the powder is completed;

[0058] S800. Replace the powder cartridge 800 or switch to a different powder cartridge via the base 700, the solenoid valve 900 cuts off the connection between the inlet and the powder feeder, and the inlet is connected to the powder-using device;

[0059] S900. The base 700 supplies different types of powders to the powder-using equipment, and the powder replacement work is completed.

[0060] The above is a specific description of the preferred implementation methods of the present application, but the invention is not limited to the embodiments.
