[0001] The invention relates to the technical field of powder extraction, in particular to a micro powder extractor. Background Art

[0002] In daily life, powders in cans are usually taken with measuring spoons, such as milk powder or condiments. On the one hand, it is easy to spill and waste during the process of taking; on the other hand, in order to facilitate taking, the opening area of ​​the can is usually designed to be larger, and the larger exposed area makes it easier for bacteria to enter, causing powder contamination.

[0003] In order to solve the above problems, the Chinese utility model patent with the authorization announcement number CN207072531U discloses an anti-pollution milk powder can that can quantitatively take milk powder, including a can body, which is divided into two parts, the upper part is a sealed holding area 1, and the lower part is a taking area 2. A baffle 3 is provided between the holding area and the taking area, and a taking port is provided on the baffle, and a self-sealing sealing plug 4 is provided at the taking port. When the milk powder can leaves the factory, the puncture and material taking tube is independently packaged and sold together with the milk powder can. When it is needed, the milk powder can is inverted, the pull rod is pulled out, the puncture and material taking tube is inserted along the puncture channel, and the pull rod is pushed into the dustproof seal, the milk powder can is turned over, and the pull rod is pulled instead, and the milk powder enters the vacuum material taking barrel along the puncture and material taking tube under vacuum negative pressure until the milk powder fills the vacuum material taking barrel, and the pull rod is pulled out to pour the milk powder out, which is the single use amount. Although the above technical solution separates the taking area from the holding area so that the handle does not touch the milk powder and thus prevents the milk powder from being contaminated, the taking process is purely manual and therefore the operation is laborious. Summary of the invention

[0004] In view of the shortcomings of the prior art, the object of the present invention is to provide a micro powder extractor, which realizes the automatic extraction of powder, thereby reducing the waste and possibility of contamination of powder and saving time and labor.

[0007] By adopting the above technical solution, the pump body is started, and the air in the powder collector can be extracted through the exhaust pipe and the filter. At this time, the powder in the tank body can enter the powder collector through the powder suction pipe and the powder inlet pipe, thereby reducing the possibility of powder spilling and contamination, thereby reducing the waste and contamination of powder; by setting a filter, the powder-containing gas entering the pump body can be filtered, thereby reducing the possibility of powder entering the pump body.

[0018] In a preferred example, the present invention can be further configured as follows: the pump body is a diaphragm pump.

[0019] By adopting the above technical solution, the advantage of the diaphragm pump is that its mechanical structure is completely isolated from the working medium, thereby reducing pollution.

[0020] In a preferred example, the present invention can be further configured as follows: the filter includes a first tube body and a filter element, the air inlet end and the air outlet end of the filter are respectively threadedly connected to the two ends of the first tube body, and the filter element is installed in the first tube body; the relative inner sides of the air inlet end and the air outlet end are respectively fixed with abutment rings, and the relative ends of the two abutment rings are respectively abutted against the two ends of the filter element.

The tank body 21 in this embodiment is a milk powder can, and the powder collector 1 is a milk bottle.

[0038] like Figure 1 and Figure 2 As shown, the suction device 2 includes a pump body 25 and a filter 3 encapsulated in a shell 22. A support plate 23 is detachably connected to the inner side of the shell 22 by bolts. A receiving cavity is formed between the support plate 23 and the top wall of the shell 22. The pump body 25 and the filter 3 are detachably connected to the support plate 23 by bolts and are located in the receiving cavity. The suction device 2 also includes a powder suction pipe 24 that passes through the bottom of the tank 21. The powder suction pipe 24 passes through the shell 22 and the support plate 23; the bottom of the powder suction pipe 24 is provided with an inclined surface 241 (see Figure 4 );like Figure 3As shown, the air outlet end 33 of the filter 3 is connected to the air inlet end of the pump body 25 through a pipeline and an air pipe joint.

The powder collector 1 is connected with an exhaust pipe 11 and a powder inlet pipe 12, and the powder inlet pipe 12 is connected with the powder suction pipe 24 through a pipeline; the exhaust pipe 11 is connected with the air inlet end 32 of the filter 3 through a pipeline and an air pipe joint; the pump body 25 is a diaphragm pump, and the air outlet end of the pump body 25 is connected with a first sleeve 4, which is sleeved outside the powder suction pipe 24 and passes into the bottom of the tank body 21 together with the powder suction pipe 24. When the pump body 25 is started, the air in the powder collector 1 can be extracted through the exhaust pipe 11 and the filter 3. At this time, the milk powder in the tank body 21 can enter the powder collector 1 through the powder suction pipe 24 and the powder inlet pipe 12, thereby reducing the possibility of milk powder spilling and being contaminated, thereby reducing the waste and contamination of milk powder; by setting the filter 3, the powder-containing gas entering the pump body 25 can be filtered, thereby reducing the possibility of milk powder entering the pump body 25.

[0039] like Figure 2 and Figure 3 As shown, the filter 3 includes a first tube body 31 and a filter element 34. The air inlet end 32 and the air outlet end 33 of the filter 3 are respectively threadedly connected to the two ends of the first tube body 31, and the filter element 34 is installed in the first tube body 31; the opposite inner sides of the air inlet end 32 and the air outlet end 33 are respectively fixed with abutment rings 35, and the opposite ends of the two abutment rings 35 are respectively abutted against the two ends of the filter element 34.

[0041] like Figure 1 and Figure 4As shown, a first seal 41 is installed between the end of the first sleeve 4 away from the bottom of the tank body 21 and the powder suction pipe 24. The material of the first seal 41 can be selected from materials such as vulcanized rubber. The second sleeve 5 is connected to the outer surface of the first sleeve 4. A channel is provided between the first sleeve 4 and the powder suction pipe 24; a channel is provided between the second sleeve 5 and the first sleeve 4.

[0042] like Figure 1 and Figure 5 As shown, the outer wall of the first sleeve 4 away from the shell 22 is fixed with a plurality of bridge breaking heads 6, which are flexible strips. The material of the bridge breaking head 6 can be selected from food-grade materials such as silicone with excellent elasticity and PE, and also includes a driving mechanism 7 for driving the first sleeve 4 to rotate. When the powder suction tube 24 sucks the milk powder, the milk powder near the powder suction tube 24 will be sucked out first, while the milk powder near the side wall of the tank body 21 is inconvenient to be sucked, so that it is easy to form a "bridge wall" in the tank body 21; by providing the bridge breaking head 6, it is convenient to break the "bridge wall", so that the powder suction tube 24 can suck the milk powder in the tank body 21.

[0043] The driving mechanism 7 includes a driving motor 71 detachably connected to the top of the support plate 23 by bolts, a gear commutator 72 installed on the output shaft of the driving motor 71, and a driving gear 73 installed on the output shaft of the gear commutator 72; a driven gear 74 is fixedly sleeved on the outer wall of the first sleeve 4, the driven gear 74 and the driving gear 73 are meshed with each other, the center of the driven gear 74 is plugged into the first sleeve 4, and the first sleeve 4 rotates with the driven gear 74.

[0044] like Figure 1As shown, the powder inlet pipe 12 includes a second tube body 121 and a third tube body 122. The second tube body 121 is connected to the opposite end of the third tube body 122. The end of the third tube body 122 away from the second tube body 121 is in the powder collector 1. The inner diameter of the third tube body 122 is greater than the inner diameter of the second tube body 121. The second tube body 121 is a small-diameter pipeline, which can enable the fluid to carry the powder at a high speed. The third pipeline is a large-diameter pipeline, which can reduce the speed of the fluid, thereby separating the gas and the powder, and thus facilitating the gas to enter the tank body 21 from the exhaust pipe 11.

[0045] The implementation principle of this embodiment is:

[0046] In order to cooperate with the use of the micro powder extractor provided by the present invention, the tank body 21 (such as a milk powder can) is modified, that is, a perforation 212 is preliminarily opened on the sealing cover 211 of the tank body 21 (milk powder can) so that the bridge breaking head 6, the first sleeve 4 and the powder suction pipe 24 enter the tank body 21, and the perforation 212 is sealed with an easily penetrable material such as aluminum foil, and an external thread that matches the internal thread of the shell 22 is processed on the outer periphery of the sealing cover 211. When in use, the sealing layer on the perforation 212 is peeled off, and then the shell 22 is screwed to the sealing cover 211 of the tank body 21, and the installation of the micro powder extractor is realized; then the pump body 25 is started, and the air in the powder collector 1 can be extracted through the exhaust pipe 11 and the filter 3. At this time, the milk powder in the tank body 21 can enter the powder collector 1 through the powder suction pipe 24 and the powder inlet pipe 12, thereby reducing the possibility of milk powder spilling, thereby reducing the waste of milk powder.

[0047] When the milk powder in the tank body 21 is extracted, the driving motor 71 is started, and the output shaft of the driving motor 71 drives the driving gear 73 to rotate, and the driving gear 73 rotates to drive the driven gear 74 to rotate, and the driven gear 74 rotates to drive the first sleeve 4 to rotate, and the first sleeve 4 rotates to drive the bridge breaking head 6 to rotate. The rotation of the bridge breaking head 6 can break the "bridge wall", so that the powder suction tube 24 can suck the milk powder in the tank body 21.

[0048] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
