[0030] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or can communicate with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] See also Figures 1 to 3 The handheld dispenser of the embodiment of the utility model includes a holding barrel 10 and a feeding assembly 20.

[0032] The holding barrel 10 has a material storage cavity 101 for storing materials and a material discharge passage 102 communicating with the material storage cavity 101. The holding barrel 10 has a dispensing discharge port 103 communicating with the material discharge passage 102.

[0033] Thus, before packaging, materials such as powdered reagents can be stored in the storage chamber 101. During packaging, the operator can hold the holding barrel 10 in hand and align the packaging outlet 103 of the holding barrel 10 with the packaging vessel.

[0034] The feeding assembly 20 includes a feeding shaft 21, a feeding blade 22 and a driving member (not shown in the figure). The feeding shaft 21 is rotatably arranged in the discharge channel 102 and extends in the direction from the storage chamber 101 to the sub-packaging discharge port 103. The feeding blade 22 is arranged on the outer peripheral wall of the feeding shaft 21 and extends in the axial spiral direction of the feeding shaft 21. The driving member is connected to the feeding shaft 21 and is used to drive the feeding shaft 21 to rotate so as to drive the feeding blade 22 to rotate. In this way, after the material enters the discharge channel 102 from the storage chamber 101, the rotating feeding blade 22 drives the material to move close to the sub-packaging discharge port 103, so that the material moves out of the sub-packaging discharge port 103 through the discharge channel 102, and then the material is automatically discharged. At this time, since the sub-packaging discharge port 103 is aligned with the sub-packaging container, the discharged material is received by the sub-packaging container.

[0035] In other words, when the hand-held dispenser of the embodiment of the utility model is used to dispense the material into the dispensing vessel, the operator can hold the holding barrel 10 by hand, align the dispensing outlet 103 of the holding barrel 10 with the dispensing vessel, and then start the driving member. In this way, the driving member drives the feeding shaft 21 to rotate, and the rotation of the feeding shaft 21 drives the feeding blade 22 to rotate, and the rotation of the feeding blade 22 drives the material stored in the holding barrel 10 to move close to the dispensing outlet 103, thereby causing the material to quickly fall from the dispensing outlet 103 to the dispensing vessel, and thus, the material is dispensed into the dispensing vessel.

[0036] In this way, the handheld dispenser of the utility model is not only small in size, easy to operate and carry, and can be flexibly applied to small-scale dispensing sites, but also has high dispensing efficiency for the materials.

[0037] According to some preferred embodiments of the present invention, refer to Figure 2 The discharge channel 102 extends vertically, and the upper end of the discharge channel 102 is connected to the storage chamber 101, and the lower end is formed as the sub-packaging discharge port 103.

[0038] Thus, when the feeding blade 22 drives the material entering the discharge channel 102 to move toward the dispensing discharge port 103, in addition to the driving force of the feeding blade 22, the material can also fall toward the dispensing discharge port 103 under the action of gravity, which helps the material to be discharged smoothly.

[0039] According to some preferred embodiments of the present invention, refer to Figure 2 The material storage chamber 101 is arranged above the material discharge channel 102, and the inner diameter of the material storage chamber 101 gradually decreases from top to bottom.

[0040] In this way, the material in the storage cavity 101 can smoothly fall into the discharge channel 102 , and then be transported out by the feeding assembly 20 in the discharge channel 102 .

[0041] According to some preferred embodiments of the present invention, refer to Figure 2 The holding barrel 10 includes a storage bin 11 and a discharge pipe 12. The storage bin 11 is formed with the storage cavity 101. The discharge pipe 12 is formed with the discharge channel 102 and the sub-packaging discharge port 103. The storage bin 11 and the discharge pipe 12 are detachably connected, so that the holding barrel 10 is easy to disassemble, easy to maintain and clean, and low in cost.

[0042] In addition, the storage bin 11 and the discharge pipe 12 can also be integrally formed. Thus, the holding barrel 10 has high strength and long service life.

[0043] According to some preferred embodiments of the present invention, refer to Figure 2 The gap distance between the outer edge of the feeding blade 22 and the inner wall of the holding barrel 10 is smaller than the particle size of the material.

[0044] In this way, when the feeding blade 22 is not rotating, the material is not easy to leak out through the gap between the outer edge of the feeding blade 22 and the inner wall of the holding barrel 10, which is helpful to avoid the material from leaking out when it is not packaged.

[0045] According to some preferred embodiments of the present invention, refer to Figure 2 and Figure 3The feeding blade 22 includes multiple layers of sub-blades 221. The multiple layers of sub-blades 221 have the same inclination angle and are evenly spaced along the axial direction of the feeding shaft 21. Such an arrangement is conducive to ensuring that when the feeding blade 22 rotates, the material can be uniformly discharged from the dispensing outlet 103 at a certain discharge rate.

[0046] Specifically, the driving member may be implemented as a driving motor, the driving shaft of which is connected to the feeding shaft 21 , so as to drive the feeding shaft 21 to rotate.

[0047] According to some preferred embodiments of the present invention, refer to Figure 3 and Figure 4 The handheld dispenser further comprises a setting button 30. The setting button 30 is arranged on the outer wall of the holding barrel 10 and is connected to the driving member, and is used to set the driving time and driving speed of the driving member driving the feeding shaft 21 each time.

[0048] It should be noted that the driving time and the driving speed refer to the rotation time and rotation speed of the feeding shaft 21 each time it rotates, and the rotation speed and rotation time of the feeding shaft 21 each time it rotates can be set through the setting button 30.

[0049] In this way, when using the handheld dispenser, the operator can set the rotation time and rotation speed of the feed shaft 21 through the setting button 30. When the rotation time and rotation speed of the feed shaft 21 are constant, the discharge amount of the dispensing outlet 103 is also constant. Thus, when the rotation time and rotation speed of the feed shaft 21 are set, the discharge amount of the dispensing outlet 103 is set. In this way, when the material is dispensed multiple times, the operator only needs to set the rotation time and rotation speed of the feed shaft 21 to be the same during multiple dispensings, so as to control the discharge amount during multiple dispensings, that is, the dispensing amount to be the same, which is conducive to ensuring that the dispensing amount of multiple dispensings is consistent, and then ensuring the dispensing uniformity of the material during multiple dispensings.

[0050] According to some preferred embodiments of the present invention, refer to Figure 4 The handheld dispenser further comprises a display 40. The display 40 is connected to the setting button 30 and is used to display the driving time and driving speed set by the setting button 30.

[0051] In this way, each time the feeding shaft 21 is packaged, the set rotation speed and rotation time can be displayed on the display 40, thereby facilitating the operator to directly observe and verify the set rotation speed and rotation time, which is helpful to avoid setting errors.

[0052] According to some preferred embodiments of the present invention, refer to Figure 4 The handheld dispenser further comprises a switch button 50. The switch button 50 is arranged on the outer wall of the holding barrel 10 and is connected to the driving member for starting the driving member.

[0053] Thus, when the handheld dispenser is required to dispense the material into the dispensing container, the operator presses the switch button 50 downward to start the driving member, thereby enabling the handheld dispenser to dispense the material efficiently and the driving member to be easily started.

[0054] According to some preferred embodiments of the present invention, refer to Figure 2 and Figure 3 The holding barrel 10 is formed with a material storage inlet 104 which is connected with the material storage cavity 101 .

[0055] The handheld dispenser further comprises a cover 60. The cover 60 is rotatably disposed at the material storage inlet 104 and is used to close or open the material storage inlet 104.

[0056] Thus, when the cover 60 rotates to a position where the material storage inlet 104 is not closed, the material can easily enter the material storage chamber 101 through the material storage inlet 104, and is stored in the material storage chamber 101. When the material storage chamber 101 is finished storing material, the cover 60 can rotate to a position where the material storage inlet 104 is closed, thereby closing the material storage inlet 104, preventing the external environment from affecting the material during the packaging process and preventing the material from overflowing through the storage inlet 104.

[0057] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
