[0003] In its process engineering, additive dispensing is an indispensable part; however, existing additive dispensing tools are inconvenient to operate, especially in powder engineering where some special materials (such as toxic or radioactive materials) are produced in sealed boxes such as glove boxes (isolation boxes), shielded glove boxes, or hot chambers. Existing additive dispensing tools are difficult to operate with gloves or master-slave robots, which affects the production process. Utility Model Content

[0004] In view of this, the present invention provides a dispensing device to solve the problem that additive dispensing tools are inconvenient to operate and also affect the production of special materials.

[0005] This utility model provides a dispensing device, comprising: a sleeve including a first tube portion and a second tube portion, wherein the inner diameter of the second tube portion is larger than the inner diameter of the first tube portion; a mandrel movably inserted into the sleeve; the mandrel and the first tube portion are sealed; the mandrel and the inner wall of the second tube portion are spaced apart; one end of the mandrel is provided with a tapered portion, and the other end is fixed with a pressure cap; the tapered portion is sealed and snapped into the opening of the second tube portion, and is adapted to limit the mandrel; an elastic element is disposed between the pressure cap and the first tube portion, and the elastic element is in a compressed state; a sample storage ring cavity is formed by the outer wall of the mandrel portion and the inner wall of the second tube portion; wherein, a sample inlet channel is provided at the mandrel, one side of the sample inlet channel is connected to the sample storage ring cavity, and the other side is connected to the outside.

[0006] In one alternative embodiment, the diameter of the cone gradually increases in the direction away from the gland.

[0007] In one optional embodiment, the cone portion has a protrusion on the side away from the pressure cap, and the second tube portion has a recess; the protrusion engages with the recess, and a first sealing ring is provided between the protrusion and the recess, the first sealing ring being sleeved on the protrusion.

[0008] In one optional embodiment, the sample inlet channel includes a first channel extending axially along the mandrel and communicating with the outside; and a second channel located around the periphery of the first channel, with both ends of the second channel communicating with the first channel and the sample storage ring cavity, respectively; wherein the second channel is inclined downward from the end connected to the first channel toward the sample storage ring cavity.

[0009] In one optional embodiment, one end of the mandrel extends out of the first tube; both ends of the elastic member are respectively connected to the gland and the first tube, and surround the periphery of the extended portion of the mandrel.

[0010] In one alternative embodiment, the axis of the first aperture is coaxial with the axis of the mandrel.

[0011] In one optional embodiment, the second passage is provided in multiple ways, the multiple second passages are spaced apart and are respectively connected to the first passage.

[0026] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] The following is combined Figures 1 to 2 The following describes embodiments of the present invention.

[0028] According to an embodiment of the present invention, a dispensing device is provided, comprising:

[0029] The sleeve 1 includes a first tube section 11 and a second tube section 12 connected and communicating with each other. The inner diameter of the second tube section 12 is larger than the inner diameter of the first tube section 11. A notch 13 is provided at the opening of the second tube section 12 on the side away from the first tube section 11.

[0030] Mandrel 2 is inserted into the sleeve 1 and can move axially up and down relative to the sleeve 1; the upper section of the mandrel 2 contacts the inner wall of the first tube 11, and the mandrel 2 and the first tube 11 are sealed; the lower section of the mandrel 2 is spaced apart from the inner wall of the second tube 12; one end of the mandrel 2 is provided with a tapered portion 7, and the other end is fixed with a pressure cap 3, which is fixed to the upper section of the mandrel 2. The tapered portion 7 is formed by protruding circumferentially from the end of the lower section of the mandrel 2. The tapered portion 7 and the first tube 12 are connected. The nozzle of the second tube section 12 is sealed and snapped together, and is used to limit the mandrel 2 when the cap 3 is released and the mandrel 2 moves upward after the filling is completed; the cone section 7 is approximately cone-shaped, and the diameter of the cone section 7 gradually increases in the direction away from the cap 3. The smaller diameter end of the cone section 7 is connected to the shaft of the mandrel 2; when there is additive in the filler, the larger diameter end of the cone section 7 is sealed and snapped together with the notch 13, so that the cone section 7 is sealed and connected to the nozzle of the second tube section 12.

[0031] The elastic element 4 is disposed between the pressure cap 3 and the first tube 11. The elastic element 4 is in a compressed state and is used to apply an upward elastic force to the pressure cap 3 when there is an additive in the dispenser, so that the core is pressed and fixed at the sleeve 1, so that the sample storage ring cavity 5 remains sealed.

[0032] The sample storage ring cavity 5 is formed by the outer wall of the mandrel 2 and the inner wall of the second tube 12, and is used to temporarily store additives. The sample storage ring cavity 5 can be annular in shape. A sample inlet channel 6 is provided at the mandrel 2. One side of the sample inlet channel 6 communicates with the sample storage ring cavity 5, and the other side communicates with the outside. The sample inlet channel 6 is used to supply additives into the sample storage ring cavity 5.

[0033] In terms of the structure of the sample inlet channel 6, the sample inlet channel 6 includes a first channel 61 and a second channel 62 that are connected. The first channel 61 extends along the axial direction of the mandrel 2 and is connected to the outside, guiding the flow of additives by gravity. The second channel 62 is located around the first channel 61, and its two ends are connected to the first channel 61 and the sample storage ring cavity 5, respectively. The second channel 62 is inclined downward from the end connected to the first channel 61 toward the sample storage ring cavity 5, which helps to introduce additives into the sample storage ring cavity 5.

[0034] In terms of the structure of the pressure cap 3, the pressure cap 3 is fixed to the spindle 2 by screws. The pressure cap 3 includes a top cover and a side cover. The screws pass through the top cover and are embedded in the spindle 2 for fixation. The side cover is arranged around the elastic element 4. The top cover of the pressure cap 3 also has a through hole 31, which corresponds to and communicates with the first hole 61. A sealing cap 8 is detachably connected to the pressure cap 3. The sealing cap 8 can be a soft rubber cap. The sealing cap 8 has an end 81. The end 81 is a sealing snap plug that plugs into the through hole 31 to seal the first hole 61.

[0035] The specific usage process of the dispenser is as follows: After the additive to be added is prepared according to the ratio, the sealing cap 8 is pulled out, and the additive is injected into the sample inlet channel 6. The sample inlet channel 6 introduces the additive into the sample storage ring cavity 5. The sample storage ring cavity 5 is kept sealed during the sample addition operation, and the additive is temporarily stored in the sample storage ring cavity 5. After the injection is completed, the sealing cap 8 is plugged to seal the sample inlet channel 6, and then the additive addition operation can be carried out. During the addition operation, the operator can hold the dispenser by hand or with the help of a tool, align the dispenser with the addition position, and then press down the pressure cap 3 on the upper side of the dispenser, so that the pressure cap 3 and the mandrel 2 move downward. The cone 7 on the lower side of the mandrel 2 leaves the opening of the second tube 12, and the lower end of the sample storage ring cavity 5 forms a discharge opening. The operator keeps pressing down the pressure cap 3, and the additive temporarily stored in the sample storage ring cavity 5 flows out, completing the additive addition. Operation: After the additive is added, the operator releases the cap 3. The cap 3 moves upward and resets under the pushing action of the elastic element 4 until the cone 7 is re-clamped to the opening of the second tube 12. The mandrel 2 stops moving upward due to the clamping action. The elastic element 4 remains in a compressed state and applies elastic force to the cap 3 to ensure that the mandrel 2 does not loosen, thereby making the sample storage ring cavity 5 re-sealed. In the addition operation, since the entire process only requires pressing and releasing the cap 3, the additive can be added. The operation is simple and reliable. It is suitable for the addition of special materials arranged in sealed boxes such as glove boxes (isolators), shielded glove boxes or hot chambers. The adder can be held and operated by gloves or master and slave robots, thereby avoiding the addition problems in the production process of special materials and ensuring smooth production.

[0036] Preferably, the injection channel 6 includes a first channel and a second channel. The first channel extends axially along the mandrel 2. The injection port of the first channel is located at the end of the mandrel 2 near the pressure cap 3. After the sealing cap 8 is removed, the injection port of the first channel is directly exposed, allowing the additive to be injected into the first channel. During operation, the first channel is set approximately vertically, allowing the additive to flow smoothly along the first channel under the influence of gravity, preventing stagnation. The additive enters the second channel along the first channel. The second channel is set inclined downwards towards the sample storage ring cavity 5, guiding the additive to flow quickly into the sample storage ring cavity 5, thus smoothly completing the additive injection operation.

[0037] Preferably, the first orifice 61 has a sample inlet at one end near the cap 3, which is connected to the outside, while the other end away from the cap 3 is located inside the mandrel 2. At least one second orifice 62 is provided at the end of the first orifice 61 away from the cap 3, that is, at least one second orifice 62 needs to be provided at the bottom of the second orifice 62 to prevent the first orifice 61 from having dead corners, and to ensure that the additive in the first orifice 61 flows into the sample storage ring cavity 5 to prevent the additive from being retained.

[0038] Preferably, one end of the mandrel 2 extends out of the first tube 11; the two ends of the elastic element 4 are respectively connected to the pressure cap 3 and the first tube 11, and surround the periphery of the extended part of the mandrel 2. The elastic element 4 can be a spring. When the mandrel 2 extends out of the sleeve 1, the extended part temporarily enters the sleeve 1 to ensure that the mandrel 2 is pressed down smoothly and to provide redundancy for the movement of the mandrel 2.

[0039] The filler provided in this application, by setting a spindle 2 inserted into the sleeve 1, and a cap 3 and elastic element 4 that cooperate with the spindle 2, allows the filling operation to be completed by pressing the cap 3 alone, thereby greatly simplifying the additive filling operation and making it highly practical.

[0040] On the one hand, the existing additive filling operation is often complicated. This application sets up a sample storage ring cavity 5 between the mandrel 2 and the sleeve 1, and achieves the temporary sealing effect of the sample storage ring cavity 5 by means of the elastic abutment of the elastic element 4 and the snap-fit ​​limiting effect of the cone 7 and the notch 13, so that the additive can be temporarily stored in it, and then the sample can be added after pressing the cap 3, thus achieving the technical effect of automatic sample addition.

[0041] On the other hand, the elastic element 4 can lift the cap 3 after the operator loosens it, causing the spindle 2 to reset and the sample storage ring cavity 5 to enter a closed state again. The operator can then inject additives into the dispenser again, thus creating an automated dispensing tool that does not require repeated manual operation. In the dispensing of special materials, the dispenser can be held and operated by gloves or master and slave robotic arms, thus successfully completing the dispensing and production.

[0042] In some embodiments, the tapered portion 7 has a protrusion 71 on the side away from the pressure cap 3, and the second tube portion 12 has a recess 13; the protrusion 71 and the recess 13 are engaged and snapped together, and a first sealing ring 72 is provided between the protrusion 71 and the recess 13. The first sealing ring 72 is sleeved on the protrusion 71, and a sealing ring groove is opened on the protrusion 71. The first sealing ring 72 is snapped into the sealing ring groove. The first sealing ring 72 can be a rubber sealing ring for radial sealing.

[0043] In some embodiments, the axis of the first hole 61 is coaxial with the axis of the mandrel 2, the first hole 61 is disposed at the center of the mandrel 2, and the second hole 62 is disposed around the first hole 61; there are multiple second holes 62, which are spaced apart and communicate with the first hole 61 respectively.

[0044] In some embodiments, a plurality of second passages 62 are arranged around the periphery of the first passage 61 at the same location to form a combination of second passages 62, and the plurality of combinations are spaced apart along the axial direction of the first passage 61.

[0045] In some embodiments, a second sealing ring 21 is further included, which is sleeved on the mandrel 2 and clamped between the mandrel 2 and the first tube 11. A sealing ring groove is provided on the mandrel 2, and the second sealing ring 21 is engaged in the sealing ring groove. A plurality of second sealing rings 21 are spaced apart along the axial direction of the mandrel 2. The second sealing ring 21 can be a rubber sealing ring, used to achieve radial sealing between the mandrel 2 and the first tube 11.

[0046] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
