DETAILED DESCRIPTION

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] A drug preparation mixer, such as Figure 1 - Figure 7 As shown, it includes a mixing tank 1, a motor 2 is installed on the top of the mixing tank 1, and a stirring rod 3 connected to the motor 2 is rotatably installed inside the mixing tank 1 for mixing the drugs.

[0036] In this embodiment, a liquid guide pipe 4 is installed on the inner wall of the mixing tank 1, and a water pump 5 connected to the liquid guide pipe 4 is installed on the outer wall of the mixing tank 1. At the same time, an infusion pipe 6 is installed at the other end of the water pump 5. When the water pump 5 is started, it will draw the medicine solution that is close to the top of the mixing tank 1 into the infusion pipe 6 through the liquid guide pipe 4. Since the bottom of the infusion pipe 6 is connected to the infusion ring 7 installed in the bottom of the mixing tank 1, and the outer wall of the infusion ring 7 is equipped with a nozzle 8, the medicine solution drawn into the infusion pipe 6 will be sprayed into the bottom of the mixing tank 1 through the infusion ring 7 and the nozzle 8, thereby improving the mixing speed of the medicine solution. The infusion pipe 6 is a transparent pipe, which makes it easy for the user to directly observe the mixing of the medicine solution that is close to the top of the mixing tank 1 from the outside.

[0037] For example, a drive mechanism 51 for driving the water pump 5 is also provided on the top of the mixing tank 1;

[0038] In some examples, the drive mechanism 51 consists of a sprocket assembly, which includes multiple sets of sprockets and chains. One set of sprockets is fixedly connected to the output end of the motor 2, and the other set of sprockets is fixedly mounted on the drive shaft of the water pump 5. The sprockets are connected to each other by chains. When the motor 2 runs, it will cause the water pump 5 to obtain rotational power synchronously, ensuring that the water pump 5 can run smoothly.

[0039] Of course, in other examples, the drive mechanism 51 may also be a motor 2 directly connected to the drive shaft of the water pump 5. In this embodiment, the specific configuration of the drive mechanism 51 is not completely limited.

[0040] For example, since the liquid guide pipe 4 has inlet ports 41 at both ends and the middle outer wall, the liquid medicine that is closer to the top of the mixing tank 1 can enter the liquid guide pipe 4 through the inlet ports 41, ensuring that the water pump 5 can smoothly draw the liquid medicine that is closer to the top of the mixing tank 1 into the infusion pipe 6 after it is started.

[0041] In this embodiment, a blocking rod 42 for blocking the liquid inlet 41 is slidably installed inside the liquid guide tube 4. Since the diameter of the blocking rod 42 corresponds to the diameter of the inner wall of the liquid guide tube 4, the blocking rod 42 can close the corresponding liquid inlet 41, making it convenient for the user to draw out the medicine at the corresponding position.

[0042] Meanwhile, this embodiment also provides a flow guide trough 43 for liquid inlet inside the shielding rod 42. The flow guide trough 43 is opened on the outer wall of the shielding rod 42 near the water pump 5. At the same time, a middle flow trough 44 corresponding to the liquid inlet 41 in the middle of the liquid guide pipe 4 is opened on the outer wall of the middle part of the shielding rod 42. Since the flow guide trough 43 and the middle flow trough 44 are connected, when the middle flow trough 44 is aligned with the liquid inlet 41, the liquid in the mixing tank 1 will enter the flow guide trough 43 through the liquid inlet 41 and the middle flow trough 44, further ensuring that the liquid will be pumped away by the water pump 5. Moreover, the length of the flow guide trough 43 is less than the length of the liquid guide pipe 4, so that when the middle flow trough 44 is aligned with the liquid inlet 41, the liquid inlets 41 at both ends of the liquid guide pipe 4 will be blocked by the two ends of the shielding rod 42, so that only one liquid inlet 41 of the liquid guide pipe 4 will be in the open state.

[0043] In some examples, the length of the liquid guide tube 4 is less than the length of the blocking rod 42, ensuring that the blocking rod 42 can slide smoothly inside the liquid guide tube 4. At the same time, the blocking rod 42 is designed in an "I" shape, which restricts the sliding trajectory of the blocking rod 42 and prevents the blocking rod 42 from sliding off the liquid guide tube 4. Furthermore, because the outer walls of both ends of the blocking rod 42 are in contact with the inner wall of the mixing tank 1, the blocking rod 42 is restricted by the mixing tank 1 during the sliding process, ensuring that the blocking rod 42 can only slide vertically on the liquid guide tube 4 and will not rotate.

[0044] When one end of the blocking rod 42 is in contact with the end of the liquid guide pipe 4, the flow guide groove 43 on the outer wall of the blocking rod 42 will be connected to the inside of the mixing tank 1. At this time, the position of the middle flow channel 44 and the liquid inlet 41 will be offset, so that the blocking rod 42 will block the two liquid inlets 41, further ensuring that only one set of liquid inlets 41 is in the open state. At the same time, since the flow guide groove 43 on the outer wall of the blocking rod 42 is now connected to the inside of the mixing tank 1, it is ensured that the water pump 5 can still draw the medicine.

[0045] For example, the mixing tank 1 is provided with an adjustment structure connected to the shielding rod 42 for adjusting the position of the shielding rod 42;

[0046] In some examples, the adjustment structure includes a transmission rod 9 mounted on top of the shielding rod 42, and a handle 10 is rotatably mounted on top of the transmission rod 9. When the user pulls the handle 10, it will drive the shielding rod 42 to move through the transmission rod 9, thereby giving the shielding rod 42 the power to slide and adjust the opened liquid inlet 41.

[0047] Meanwhile, the handle 10 is provided with a positioner 11 at the top of the mixing tank 1, and the positioner 11 is provided with a position slot 12 corresponding to the handle 10, so that the movement of the handle 10 is limited by the positioner 11 and the position slot 12, preventing the user from pulling the handle 10 too hard and causing an accident;

[0048] It should be noted that the position slot 12 is an E-shaped slot composed of three horizontal slots and a longitudinal slot, wherein the three horizontal slots and the longitudinal slot of the position slot 12 are communicated, the width of the horizontal slot corresponds to the diameter of the end of the handle 10, and the distance between the three horizontal slots corresponds to the distance that the shielding rod 42 needs to slide when adjusting the liquid inlet 41, so that when the handle 10 slides into a horizontal slot, the shielding rod 42 just slides to a state of shielding two liquid inlets 41, and the position where the handle 10 contacts the horizontal slot and the position where the positioner 11 is provided with the horizontal slot are both made of magnets, so that after the handle 10 enters the horizontal slot, it is limited under the action of the magnet, and the edge of the connection position between the horizontal slot and the longitudinal slot is designed as an inclined angle, which effectively reduces the difficulty of the handle 10 entering the horizontal slot.

[0049] The working principle of the utility model is as follows: when it is necessary to mix the medicine, the medicine raw material is placed into the mixing tank 1, then the motor 2 is started to make the stirring rod 3 rotate to mix the medicine uniformly;

[0050] At the same time, the driving mechanism 51 is started to make the water pump 5 start to operate, which will draw the medicine liquid near the top of the mixing tank 1 into the infusion pipe 6 through the liquid guide pipe 4, and then the medicine liquid will be sprayed into the bottom of the mixing tank 1 through the infusion ring 7 and the spray head 8, so that the medicine deposited at the bottom of the mixing tank 1 is impacted by the medicine liquid sprayed from the spray head 8, the mixing effect of the medicine is accelerated, and the mixing speed of the medicine is effectively improved;

[0051] When the liquid level in the mixing tank 1 is different during mixing, when the liquid level is higher than the liquid inlet 41 at the top of the liquid guide pipe 4, the user pulls the handle 10 upward until it contacts the top of the position slot 12, and then rotates the handle 10 to make it enter the horizontal slot at the top of the position slot 12, in this process, the transmission rod 9 drives the shielding rod 42 to move upward, so that the bottom of the shielding rod 42 enters the liquid guide pipe 4 to shield the liquid inlet 41 at the bottom of the liquid guide pipe 4, and the middle flow groove 44 of the side wall of the shielding rod 42 is also offset from the liquid inlet 41 at the middle of the liquid guide pipe 4, so that the liquid inlets 41 at the bottom and the middle of the liquid guide pipe 4 are both closed by the shielding rod 42;

[0052] When the liquid level is lower than the top liquid inlet 41 of the liquid guide pipe 4 and higher than the middle liquid inlet 41 of the liquid guide pipe 4, the user adjusts the handle 10 into the middle transverse slot of the positioning groove 12, so that the middle flow groove 44 corresponds to the middle liquid inlet 41 of the liquid guide pipe 4, and at this time, the top and bottom liquid inlets 41 of the liquid guide pipe 4 are both closed;

[0053] When the liquid level is lower than the middle liquid inlet 41 of the liquid guide pipe 4 and higher than the bottom liquid inlet 41 of the liquid guide pipe 4, the user adjusts the handle 10 into the bottom transverse slot of the positioning groove 12, so that the middle flow groove 44 is misaligned with the middle liquid inlet 41 of the liquid guide pipe 4, and at this time, the top liquid inlet 41 of the liquid guide pipe 4 and the middle liquid inlet 41 of the liquid guide pipe 4 are both closed, and the bottom liquid inlet 41 of the liquid guide pipe 4 is opened, so that when the liquid level in the mixing tank 1 is different, the liquid near the top of the mixing tank 1 can still be drawn to the bottom of the mixing tank 1 for mixing.

[0054] Although the embodiments of the present application have been shown and described, the specific embodiments are only an explanation of the present application, and are not a limitation of the present application, and the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner, and those skilled in the art can make modifications, replacements and variations of the embodiments without creative contribution after reading the specification, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
