DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Please refer to Figure 1 , Figure 2 and Figure 3 The present invention provides a dispensing bottle head, comprising a bottle mouth structure 1, an opening and closing structure, and a diversion structure 2 located between the bottle mouth structure 1 and the opening and closing structure;

[0037] The bottle mouth structure 1 has a bottle mouth 11 for connecting with a dispensing bottle;

[0038] The diverter structure 2 has a feed port 21, m discharge ports 22 and m slideways 23. The feed port 21 is located on a side of the diverter structure 2 adjacent to the bottle mouth structure 1 and is connected to the bottle mouth 11. The m discharge ports 22 are located on a side of the diverter structure 2 adjacent to the opening and closing structure. The m discharge ports 22 correspond to the m slideways 23 one by one. Each discharge port 22 is connected to the feed port 21 via a corresponding slideway 23. m is an integer equal to or greater than 2.

[0039] The opening and closing structure includes m gate plates 3 corresponding to the m discharge ports 22 one by one. Each gate plate 3 is rotatably connected to the diversion structure 2 . Each gate plate 3 is used to open or close the corresponding discharge port 22 .

[0040] The dispensing bottle head provided by the embodiment of the present invention includes a bottle mouth structure 1, an opening and closing structure, and a diverter structure 2 located between the bottle mouth structure 1 and the opening and closing structure, wherein the feed port 21 of the diverter structure 2 is connected to the bottle mouth of the bottle mouth structure 1, and the m slideways 23 of the diverter structure 2 can distribute the medicinal material particles flowing into the feed port 21 from the bottle mouth into m portions, and transport them to m discharge ports 22 respectively, each discharge port 22 can be used to fill a corresponding medicine bag, and the gate 3 in the opening and closing structure is used to open or close the corresponding discharge port 22, thereby adjusting the discharge state of the medicinal material particles. Therefore, the above-mentioned dispensing bottle head can realize the filling of multiple medicine bags with the same dispensing bottle through the diverter structure 2, thereby improving the production efficiency of traditional Chinese medicine preparations.

[0041] The bottle mouth can be threadedly connected to the dispensing bottle to achieve a sealed connection at the bottle mouth to prevent the medicinal material particles from being exposed at the bottle mouth.

[0042] The number of the slideway 23 and the discharge port 22 in the diversion structure 2 can be two, such as Figure 2 As shown, the dispensing bottle can fill two medicine bags at the same time, thereby improving the production efficiency of Chinese medicine. Specifically, the number of slideways 23 and discharge ports 22 in the diversion structure 2 is not limited here and is determined according to actual conditions.

[0043] In the embodiment of the present invention, Figure 1 As shown, m discharge ports 22 can be arranged circumferentially along the center line of the diversion structure 2, and m gate plates 3 are connected to the diversion structure 2 via a connecting shaft 4 located in the middle of the m discharge ports 22. The axis of the connecting shaft 4 coincides with the center line of the diversion structure 2. The structure is simple, and the rotation opening and closing of the gate plates 3 in the opening and closing structure can be easily realized.

[0044] Specifically, the gate plate 3 may be in a fan-shaped shape, the connecting shaft 4 may be fixedly connected to the diversion structure 2, and each gate plate 3 may be loosely matched with the connecting shaft 4, so that each gate plate 3 may be rotated individually, and the discharge of each discharge port 22 may be controlled individually. The gate plate 3 may be driven to rotate by an external force to open and close the discharge port 22, and the flow rate of the medicinal material particles flowing out of the discharge port 22 may be controlled by the size of the rotation angle of the gate plate 3. For example, the gate plate 3 may also have a driving notch, and the driving device may drive the gate plate 3 to rotate by engaging with the driving notch.

[0045] Specifically, Figure 2 and Figure 3As shown, the center line of the feed port 21 can coincide with the center line of the diverter structure 2, the discharge port 22 can be arranged adjacent to the outer wall of the diverter structure 2, and each slideway 23 has an inclined guide surface 231, which extends from a position adjacent to the feed port 21 to a position of the discharge port 22. The Chinese medicine particles flow from the feed port 21 to the discharge port 22 by gravity, and the inclined guide surface 231 can guide the medicinal materials at the feed port 21 to flow to the feed port better and faster, so as to facilitate the filling of the medicine.

[0046] Specifically, the material of the channel can be determined according to actual conditions, and the inclination angle of the inclined guide surface 231 can be determined according to actual conditions. The inclined guide surface 231 can be coated to reduce the friction between the sliding and the medicinal material particles.

[0047] In the embodiment of the present invention, Figure 3 and Figure 4 As shown, the gate 3 may include a connecting portion 31 and a sealing portion 32, the connecting portion 31 is rotatably connected to the connecting shaft 4, and the sealing portion 32 is used to close or open the discharge port 22; wherein, the dispensing bottle head may also include a pressing plate 5 located on the side of the connecting portion 31 away from the diversion structure 2, the pressing plate 5 makes the sealing portion 32 in close contact with the area where the corresponding discharge port 22 is located, which can ensure that when the gate 3 rotates to the position of closing the discharge port 22, the discharge port 22 is effectively sealed to prevent the medicinal material particles from leaking out of the discharge port 22.

[0048] The pressing plate 5 can be fixedly connected to the diversion structure 2 by screws to ensure the pressing of the connecting portion 31 of the gate plate 3 .

[0049] In the embodiment of the present invention, Figure 3 As shown, a return spring 6 may be provided in the area where the connection portion 31 of the gate plate 3 is connected to the connection shaft 4. The return spring 6 may enable the gate plate 3 to close the discharge port 22 without external force, thereby preventing the medicinal material particles from leaking out of the discharge port 22 when the dispensing bottle is not in use.

[0050] Specifically, Figure 3 and Figure 4The opening and closing structure may have two gates 3 corresponding to the two feed ports 21, and the connection portion 31 of the gate 3 may have a connection hole, and the connection hole and the connection shaft 4 may be clearance-matched, and the rotation of each gate 3 may be controlled individually, and the rotation directions of the two gates 3 may be opposite. The above-mentioned reset spring 6 may be a torsion spring located between the connection portions 31 of the two gates 3, and the torsion spring may be sleeved on the area of ​​the connection hole surrounded by the connection portion 31 of one gate 3, and the two ends of the torsion spring may be fixedly connected to the connection portion 31 of the other gate 3 and the pressure plate 5, respectively. Among them, when the driving device drives the gate 3 to rotate from the position of closing the discharge port 22 to the position of opening the discharge port 22, the reset spring 6 may be in a force storage state, and if the driving device does not apply an external force to the gate 3, the reset spring 6 may drive the gate 3 to return to the position of closing the discharge port 22 during the process of returning to the initial state.

[0051] In the embodiment of the present invention, Figure 3 As shown, the side of the diversion structure 2 facing the opening and closing structure may have a receiving groove A, and the receiving groove A is located in the middle of the m discharge ports 22. The connecting shaft 4, the connecting portion 31 of the gate plate 3 and the pressing plate 5 are located in the receiving groove A. The surface of the pressing plate 5 facing away from the connecting portion 31 may be flush with the surface of the sealing portion 32 of the gate plate 3 facing away from the diversion structure 2. When the adjusting bottle is not in use, the adjusting bottle can be conveniently placed vertically.

[0052] In the embodiment of the present invention, Figure 5 and Figure 6 As shown, the side of the diversion structure 2 facing the opening and closing portion may have m first limiting grooves 24 corresponding to the sealing portions 32 of the m gate plates 3, the discharge port 22 is exposed from the bottom of the corresponding first limiting grooves 24, the sealing portions 32 are located in the corresponding first limiting grooves 24, and the two side walls of the first limiting grooves 24 arranged circumferentially along the connecting shaft 4 can be used to limit the rotation range of the gate plate 3. The first limiting grooves 24 can limit the rotation angle of the gate plate 3, which is convenient for controlling the gate plate 3. For example, under the action of the reset spring 6 and one side wall of the first limiting groove 24, when no external force is applied to the gate plate 3, the gate plate 3 can be in a position to close the discharge port 22.

[0053] In the embodiment of the present invention, Figure 3 and Figure 4As shown, the area of ​​each connection part 31 adjacent to the sealing part 32 may have an arc-shaped sealing plate 311 matched with the first limiting groove 24; the side of the diversion structure 2 facing the connection part 31 may have a first sealing groove 25 matched with the arc-shaped sealing plate 311, and the bottom of the first sealing groove 25 is in close contact with the arc-shaped sealing plate 311; the side of the pressing plate 5 facing the connection part 31 has a second sealing groove 51 matched with the arc-shaped sealing plate 311, and the bottom of the second sealing groove 51 is in close contact with the arc-shaped sealing plate 311. Through the cooperation of the first sealing groove 25 and the second sealing groove 51 with the arc-shaped sealing plate 311, the area corresponding to the connection part 31 and the first limiting groove 24 can be sealed, and the medicinal material particles can be prevented from entering the area where the rotating shaft and the connection part 31 are connected, which can increase the service life of the bottle head.

[0054] The second sealing groove 51 may be a stepped groove provided on the pressure plate 5 , which is not limited here, and may also be other groove types, depending on actual conditions.

[0055] In the embodiment of the present invention, Figure 6 As shown, the two side surfaces of the sealing portion 32 of the gate 3 arranged along the circumferential direction of the connecting shaft 4 may both have a first inclined surface 321, and the angle between the first inclined surface 321 and the bottom of the first limiting groove 24 is an obtuse angle. The first inclined surface 321 on the sealing portion 32 can push the medicinal material particles accumulated near the discharge port 22 to the side wall of the first limiting groove 24 during the rotation process, and the particles fall from the first limiting groove 24, thereby preventing the accumulation of medicinal material particles at the discharge port 22 and affecting the closing and opening of the discharge port 22 by the gate 3;

[0056] Among them, Figure 5 As shown, the two side walls of the first limiting groove 24 arranged along the circumferential direction of the diverter structure 2 may both include a second inclined surface 241 and a vertical surface 242, the second inclined surface 241 corresponds to the first inclined surface 321, and the angle between the second inclined surface 241 and the bottom of the first limiting groove 24 is an obtuse angle, and the vertical surface 242 is perpendicular to the bottom of the first limiting groove 24 and connected to the side of the second inclined surface 241 away from the bottom of the first limiting groove 24. The second inclined surface 241 on the side wall of the first limiting groove 24 can reduce the contact area between the sealing part 32 and the side wall, and can reduce the probability of powder stuck at the side wall of the first limiting groove 24. In addition, the vertical surface 242 of the first limiting groove 24 can be used to block the range of medicinal material particles scraped off when the sealing part 32 rotates and flying to the side wall, thereby reducing the proportion of medicinal material particles spilling outside the medicine bag.

[0057] In the embodiment of the present invention, Figure 6As shown, the area near the opening and closing part of the outer wall of the above-mentioned diverter structure 2 may have m second limiting grooves 26 corresponding to m gates, and the groove bottom of the second limiting groove 26 has a limiting protrusion 261 extending along the circumferential direction of the diverter structure 2, and the position of the limiting protrusion 261 is opposite to the position of the corresponding discharge port 22; the gate 3 may also include a limiting portion 33 connected to the sealing portion 32, the limiting portion 33 is located in the second limiting groove 26, and the limiting portion 33 has a slide groove 331 that cooperates with the limiting protrusion 261 on the side facing the limiting protrusion 261. The limiting protrusion 261 in the second limiting groove 26 cooperates with the slide groove 331 of the gate 3, so that the gate 3 can be limited to move along the extension direction of the center line of the diverter structure 2, ensuring that the gate 3 can well seal the discharge port 22.

[0058] In an embodiment of the present invention, the outer wall of the diversion structure 2 may further have a slot near the opening and closing portion, through which the dispensing bottle head and the drive device may be engaged to ensure the connection between the dispensing bottle head and the drive device.
