[0004] However, the current intelligent density measuring instrument has the following problems: when the intelligent density measuring instrument is in use, since the liquid medicine is easily mixed with bubbles and enters the measuring instrument during the process of entering the equipment, which leads to inaccurate measurement of the medicine density. Therefore, we propose a medicine density measuring instrument. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a drug density measuring instrument, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the present invention is implemented through the following technical solutions: a drug density measuring instrument, including an electronic scale, an L-shaped frame is fixedly installed in the middle of the back of the electronic scale, a motor is penetrated and fixed on the top surface of the L-shaped frame, a tank body is fixedly installed on the top surface of the electronic scale, a round rod is fixed at the bottom end of the motor shaft, the round rod is penetrated and rotatably installed in the middle of the top surface of the tank body, a round tube is fixed at the bottom of the outer wall of the round rod, an anti-accumulation device is arranged on the bottom surface of the round tube, the anti-accumulation device is used for the drug density measuring instrument to stir the drug at the bottom of the tank body during measurement, an anti-adhesion device is arranged on the bottom surface of the anti-accumulation device, the anti-adhesion device is used for the drug density measuring instrument to scrape off the drug particles attached to the wall surface of the tank body during measurement, three circular frames are fixed on the outer wall of the circular tube, the three circular frames are suspended below the inside of the tank body, a metal mesh is fixed on the inner wall of each circular frame, and the metal mesh stirs the liquid drug in the round tank during rotation, so that the mesh seams of the metal mesh stir the bubbles in the liquid drug, and the bubbles in the liquid drug are quickly discharged upward.

[0007] According to the above technical solution, the tank body includes a round tank, an L-shaped liquid inlet pipe, a round cover and an exhaust pipe. The round tank is fixed on the top surface of the electronic scale. The L-shaped liquid inlet pipe passes through and is fixed on the top of the left side of the round tank. The round cover is fixedly installed on the top surface of the round tank. The middle of the top surface of the round cover passes through and is rotatably connected to the outer wall of the round rod. The exhaust pipe passes through and is fixed on the top surface of the round cover. The exhaust pipe is located on the right side of the motor.

[0008] According to the above technical solution, a display screen is arranged in the middle of the front of the electronic scale, rubber pads are arranged on the four sides of the bottom of the electronic scale, a reinforcing plate is arranged on the inner wall of the L-shaped frame, and the reinforcing plate of the L-shaped frame is located behind the tank body.

[0009] According to the above technical solution, a disc is fixed to the bottom surface of the circular tube, four L-shaped rods are fixed to the bottom surface of the disc, a connecting tube is fixed to the outer wall of each of the L-shaped rods, and square plates are fixed to the outer walls of the four connecting tubes. During the forward rotation of the square plates, the square plates stir the liquid medicine under the round tank to prevent bubbles from accumulating under the round tank, a vertical plate is fixed to the end of each L-shaped rod away from the disc, an L-shaped plate is fixed to the side of each vertical plate away from each L-shaped rod, and an arc block is fixed to the end of each L-shaped plate away from each vertical plate, and the outer walls of the four arc blocks are in sliding contact with the bottom of the inner wall of the round tank. During the rotation of the arc blocks, the arc blocks scrape off the medicine particles attached to the angle of the round tank to prevent the medicine particles from accumulating at the angle of the round tank, making it difficult to clean the angle of the round tank.

[0010] According to the above technical solution, the circular disc is located below the three circular frames, and the four square plates are respectively arranged obliquely on the outer walls of the four connecting tubes.

[0011] According to the above technical solution, a straight ring block is fixed to the top of the outer wall of each L-shaped rod, and the four straight ring blocks are respectively located above the square plates. A round shell is fixed to one end of the four straight ring blocks close to each other, and a counterweight ball is rotatably installed on the inner wall of the round shell. The straight ring block drives the round shell to rotate forward. Under the action of centrifugal force, the counterweight ball rolls in the round shell, and the counterweight ball hits the wall of the round shell, causing the round shell to vibrate. The round shell transmits the vibration to the square plate, so that the square plate can vibrate out the bubbles accumulated under the round tank during the process of rotating and stirring the liquid.

[0012] According to the above technical solution, the round shell is located below the round disc, and the round shell is suspended below the inside of the round tank.

Under the elastic force of the arc-shaped spring piece, the chamfered plate presses against the wall of the circular tank, so that the chamfered plate can scrape off the drug particles attached to the wall of the circular tank during the rotation process.

[0014] According to the above technical solution, a circular frame is fixed on the surface of each of the vertical slats, and a thin rod is fixed on the surface of each of the circular frames. A ring block is fixed at one end of the two thin rods close to each other, and the inner wall of the ring block is fixedly connected to the outer wall of the round rod. The ring block supports the circular frame, and the circular frame supports the vertical slats, so that the vertical slats will not be deformed when the vertical slats rotate.

[0015] According to the above technical solution, the outer walls of the two chamfered plates are in sliding contact with the inner wall of the round can, and the two circular racks are located above the three circular frames.

[0016] The present invention provides a drug density measuring instrument, which has the following beneficial effects: (1) The present invention uses an electronic scale, an L-shaped frame, a motor, a tank body, a round rod, a round tube and a circular frame in conjunction with a metal mesh. The round tube drives the circular frame to rotate forward, and the circular frame drives the metal mesh. When the metal mesh rotates, the metal mesh stirs the liquid medicine in the round tank, so that the mesh slits of the metal mesh stir the bubbles in the liquid medicine, and the bubbles in the liquid medicine are quickly discharged upward, thereby preventing the liquid medicine from containing a large number of bubbles, which may cause inaccurate measurement of the drug density.

[0017] (2) The present invention arranges an anti-accumulation device so that the disc, L-shaped rod, connecting tube, square plate, vertical plate and L-shaped plate cooperate with the arc block. When the plate rotates forward, the square plate stirs the liquid medicine under the round tank, so that bubbles will not accumulate under the round tank, thus preventing the accumulation of bubbles under the round tank and causing poor exhaust effect of the equipment. In addition, the L-shaped rod drives the vertical plate to rotate forward, the vertical plate drives the L-shaped plate to rotate forward, and the L-shaped plate drives the arc block to rotate forward. When the arc block rotates, the arc block scrapes off the medicine particles attached to the corner of the round tank, thus preventing the medicine particles from accumulating at the corner of the round tank and making it difficult to clean the corner of the round tank.

[0018] (3) The present invention sets an anti-accumulation device so that the straight ring block and the round shell cooperate with the weighted ball. The straight ring block drives the round shell to rotate forward. Under the action of centrifugal force, the weighted ball rolls in the round shell and hits the wall of the round shell, causing the round shell to vibrate. The round shell transmits the vibration to the square plate, so that the square plate can vibrate out the bubbles accumulated under the round tank during the process of rotating and stirring the liquid, thereby preventing the bubbles under the round tank from being difficult to be discharged, resulting in poor measurement effect of the equipment.

[0019] (4) The present invention sets an anti-adhesion device so that the horizontal plate, the vertical plate and the arc-shaped spring sheet cooperate with the chamfer plate. Under the elastic force of the arc-shaped spring sheet, the chamfer plate presses against the wall of the round can. During the rotation of the chamfer plate, the chamfer plate scrapes off the drug particles attached to the wall of the round can, thereby preventing a large number of drug particles from adhering to the wall of the round can after the drug density measuring instrument is used for measurement, which makes it inconvenient to clean the density measuring instrument later.

[0020] (5) The present invention provides an anti-adhesion device so that the circular frame and the thin rod cooperate with the ring block, the ring block supports the circular frame, and the circular frame supports the vertical strips, so that the vertical strips will not be deformed when they rotate, thereby preventing the vertical strips from deforming and causing poor scraping effect of the chamfered plate.

The anti-accumulation device 9 is used for the drug density measuring instrument to stir the drug at the bottom of the tank body 4 during measurement. The bottom surface of the anti-accumulation device 9 is provided with an anti-adhesion device 10. The anti-adhesion device 10 is used for the drug density measuring instrument to scrape off the drug particles attached to the wall of the tank body 4 during measurement. Three circular frames 7 are fixed on the outer wall of the circular tube 6. The three circular frames 7 are suspended below the inside of the tank body 4. A metal mesh 8 is fixed to the inner wall of each circular frame 7. The circular tube 6 drives the circular frame 7 to rotate forward, and the circular frame 7 drives the metal mesh 8, so that during the rotation of the metal mesh 8, the metal mesh 8 stirs the liquid drug in the round tank 41, and the mesh seams of the metal mesh 8 stir the bubbles in the liquid drug, and the bubbles in the liquid drug are quickly discharged upward, so as to avoid the inaccurate measurement of the drug density caused by a large number of bubbles in the liquid drug when the drug density measuring instrument measures the density.

[0025] Since liquid medicine is easily mixed with bubbles and enters the measuring instrument during the process of entering the equipment, when in use, the operator inputs 200 milliliters of liquid medicine from the L-shaped liquid inlet pipe 42, and the liquid medicine enters the round tank 41. The operator starts the electronic scale 1, and the electronic scale 1 weighs the mass of gas contained in the liquid medicine in the round tank 41. The density calculation formula is ρ=m / V, where ρ is density, m is mass, and V is volume. The volume of 200 milliliters of liquid medicine is 200 cubic centimeters. The volume of 200 cubic centimeters is entered in the electronic scale 1. The program in the electronic scale 1 calculates the density of the liquid medicine containing bubbles according to the formula ρ=m / V. At the same time, the operator starts the motor 3 on the L-shaped frame 2, and the shaft of the motor 3 starts to rotate forward. The shaft of the motor 3 drives the round rod 5 to rotate forward. The round rod 5 rotates forward in the round cover 43, and the round rod 5 drives the round tube 6 The circular tube 6 rotates forward, and the circular frame 7 rotates forward, and the circular frame 7 drives the metal mesh 8, so that the metal mesh 8 stirs the liquid medicine in the circular tank 41 during the rotation, and the mesh gaps of the metal mesh 8 stir the bubbles in the liquid medicine, and the bubbles in the liquid medicine are quickly discharged upward, and the bubbles enter the exhaust pipe 44 upward, and the exhaust pipe 44 discharges the gas. At this time, the volume of the liquid medicine in the circular tank 41 is in a gas-free state, and the volume of the medicine without gas is obtained through the milliliter mark on the circular tank 41. The volume data of the medicine without gas is input into the electronic scale 1. The program in the electronic scale 1 obtains the density of the liquid medicine without gas according to the above formula, so as to prevent the liquid medicine from containing a large number of bubbles when the equipment is in use, thereby avoiding the problem of inaccurate measurement of the density of the medicine caused by the large number of bubbles in the liquid medicine when the medicine density measuring instrument measures the density.

[0026] See also Figure 1-Figure 8On the basis of the above embodiment, in another embodiment of the present invention, a disc 91 is fixed to the bottom surface of the circular tube 6, four L-shaped rods 92 are fixed to the bottom surface of the disc 91, a connecting tube 93 is fixed to the outer wall of each L-shaped rod 92, and square plates 94 are fixed to the outer walls of the four connecting tubes 93, respectively. The disc 91 is located below the three circular frames 7, and the four square plates 94 are respectively tilted on the outer walls of the four connecting tubes 93. The L-shaped rod 92 drives the connecting tube 93 to rotate forward, and the connecting tube 93 drives the square plates 94 to rotate forward. During the forward rotation of the square plates 94, the square plates 94 stir the liquid medicine under the round tank 41, so that bubbles will not accumulate under the round tank 41, so as to avoid the accumulation of bubbles under the round tank 41 when the medicine density measuring instrument measures the density, causing the device to be damaged. The exhaust effect is not good. A vertical plate 95 is fixed to one end of each L-shaped rod 92 away from the disc 91, an L-shaped plate 96 is fixed to one side of each vertical plate 95 away from each L-shaped rod 92, and an arc block 97 is fixed to one end of each L-shaped plate 96 away from each vertical plate 95. The outer walls of the four arc blocks 97 are in sliding contact with the bottom of the inner wall of the round tank 41. The L-shaped rod 92 drives the vertical plate 95 to rotate forward, the vertical plate 95 drives the L-shaped plate 96 to rotate forward, and the L-shaped plate 96 drives the arc block 97 to rotate forward. During the rotation of the arc block 97, the arc block 97 scrapes off the drug particles attached to the angle of the round tank 41, so as to avoid the problem that the drug particles accumulate at the angle of the round tank 41 when the drug density measuring instrument measures the density, making the angle of the round tank 41 difficult to clean.

[0027] A straight ring block 98 is fixed to the top of the outer wall of each L-shaped rod 92, and the four straight ring blocks 98 are respectively located above the square plate 94. A round shell 99 is fixed to one end of the four straight ring blocks 98 that is close to each other. A counterweight ball 910 is rotatably installed on the inner wall of the round shell 99. The round shell 99 is located below the disc 91. The round shell 99 is suspended below the inside of the round tank 41. The straight ring block 98 drives the round shell 99 to rotate forward. Under the action of centrifugal force, the counterweight ball 910 rolls in the round shell 99, and the counterweight ball 910 hits the wall of the round shell 99, and the round shell 99 vibrates. The round shell 99 transmits the vibration to the square plate 94, so that the square plate 94 can vibrate out the bubbles accumulated under the round tank 41 during the process of rotating and stirring the liquid, so as to avoid the poor measurement effect of the equipment caused by the difficulty in discharging the bubbles under the round tank 41 when the drug density measuring instrument measures the density.

[0028] A horizontal plate 101 is fixed to the bottom surface of the circular shell 99, and vertical strips 102 are fixed to both ends of the horizontal plate 101. An arc-shaped spring piece 103 is fixed to the surface of each vertical strip 102, and a chamfered plate 104 is fixed to the side of each arc-shaped spring piece 103 away from each vertical strip 102. The outer walls of the two chamfered plates 104 are in sliding contact with the inner wall of the round can 41, and the vertical strip 102 drives the arc-shaped spring piece 103 to rotate forward, and the arc-shaped spring piece 103 drives the chamfered plate 104 to rotate forward. Under the elastic force of the arc-shaped spring piece 103, the chamfered plate 104 presses against the wall of the round can 41, so that the chamfered plate 104 scrapes off the drug particles attached to the wall of the round can 41 during the rotation process, so as to avoid a large number of drug particles attached to the wall of the round can 41 after the drug density measuring instrument is measured, which makes it inconvenient to clean the density measuring instrument later.

[0029] A circular frame 105 is fixed on the surface of each vertical strip 102, and a thin rod 106 is fixed on the surface of each circular frame 105. A ring block 107 is fixed at one end of the two thin rods 106 close to each other. The inner wall of the ring block 107 is fixedly connected to the outer wall of the round rod 5. The two circular frames 105 are located above the three circular frames 7. The circular frames 105 drive the thin rods 106 to rotate forward, and the thin rods 106 drive the ring blocks 107 to rotate forward, so that the ring blocks 107 support the circular frames 105, and the circular frames 105 support the vertical strips 102, so that the vertical strips 102 will not be deformed when rotating, so as to avoid the deformation of the vertical strips 102 when the drug density measuring instrument is measuring the density, resulting in poor scraping effect of the chamfered plate 104.

[0030] Before measuring the density of the liquid medicine without gas, the round rod 5 drives the round tube 6 to rotate forwardly, while the round tube 6 drives the disc 91 to rotate forwardly, the disc 91 drives the L-shaped rod 92 to rotate forwardly, the L-shaped rod 92 drives the connecting tube 93 to rotate forwardly, and the connecting tube 93 drives the square plate 94 to rotate forwardly. During the forward rotation of the square plate 94, the square plate 94 stirs the liquid medicine under the round tank 41, so that bubbles will not accumulate under the round tank 41, thereby preventing bubbles from accumulating under the round tank 41 when the equipment is in use, thereby avoiding bubbles from accumulating under the round tank 41 when the medicine density measuring instrument measures the density. To solve the problem of poor exhaust effect of the equipment, while the disc 91 drives the L-shaped rod 92 to rotate forward, the L-shaped rod 92 also drives the vertical plate 95 to rotate forward, the vertical plate 95 drives the L-shaped plate 96 to rotate forward, and the L-shaped plate 96 drives the arc block 97 to rotate forward. During the rotation of the arc block 97, the arc block 97 scrapes off the drug particles attached to the corner of the round tank 41 to prevent the drug particles from accumulating at the corner of the round tank 41 when the equipment is in use, thereby avoiding the problem that the drug particles accumulate at the corner of the round tank 41 when the drug density measuring instrument measures the density, making the corner of the round tank 41 difficult to clean.

[0031] While the disc 91 drives the L-shaped rod 92 to rotate forward, the L-shaped rod 92 drives the straight ring block 98 to rotate forward, and the straight ring block 98 drives the round shell 99 to rotate forward. Under the action of centrifugal force, the counterweight ball 910 rolls in the round shell 99, and the counterweight ball 910 hits the wall of the round shell 99, causing the round shell 99 to vibrate. The round shell 99 transmits the vibration to the square plate 94, so that the square plate 94 can vibrate out the bubbles accumulated under the round tank 41 during the process of rotating and stirring the liquid, thereby preventing the bubbles under the round tank 41 from being difficult to be discharged when the equipment is in use, thereby avoiding the problem of poor measurement effect of the equipment due to the bubbles under the round tank 41 being difficult to be discharged when the drug density measuring instrument is measuring the density.

[0032] While the straight ring block 98 drives the round shell 99 to rotate forward, the round shell 99 drives the horizontal plate 101 to rotate forward, the horizontal plate 101 drives the vertical bar plate 102 to rotate forward, the vertical bar plate 102 drives the arc spring piece 103 to rotate forward, and the arc spring piece 103 drives the chamfered plate 104 to rotate forward. Under the elastic force of the arc spring piece 103, the chamfered plate 104 presses against the wall of the round tank 41, so that the chamfered plate 104 can scrape off the drug particles attached to the wall of the round tank 41 during the rotation process, so as to prevent a large number of drug particles from being attached to the wall of the round tank 41 after the equipment is used, thereby avoiding the problem that a large number of drug particles are attached to the wall of the round tank 41 after the drug density measuring instrument is measured, causing inconvenience in subsequent cleaning of the density measuring instrument.

[0033] The horizontal plate 101 drives the vertical strip 102 to rotate forward, the vertical strip 102 drives the circular frame 105 to rotate forward, the circular frame 105 drives the thin rod 106 to rotate forward, the thin rod 106 drives the ring block 107 to rotate forward, the ring block 107 supports the thin rod 106, the thin rod 106 supports the circular frame 105, and the circular frame 105 supports the vertical strip 102, so that the vertical strip 102 will not be deformed when rotating, preventing the vertical strip 102 from deforming when the equipment is in use, thereby avoiding the problem of poor scraping effect of the chamfered plate 104 caused by the deformation of the vertical strip 102 when the drug density measuring instrument measures the density.
