DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] Embodiment 1:

[0030] See also Figure 1-5 The present embodiment discloses a food and drug homogeneity detection device, including a base 1, a circular shell 5 and a rotating shaft 6. An opening is provided in the middle position of the top side of the circular shell 5. An opening and closing cover plate 4 is installed on the opening of the circular shell 5. A plurality of metal spheres 7 are provided in the inner cavity of the circular shell 5.

[0031] The top side of the base 1 and the bottom end of the rotating shaft 6 are connected by a bearing or a pin, the top end of the rotating shaft 6 and the middle position of the bottom side of the circular shell 5 are detachably connected, a coaxial gear 10 is fixed on the outer peripheral side of the rotating shaft 6, a sliding gear rod 12 is installed on the top side of the base 1, the gear rod 12 slides along the length direction of the gear rod 12 on the top side of the base 1, the gear rod 12 and the gear 10 are meshed, a motor 15 is installed on the top side of the base 1, a disc 14 is coaxially fixed on the output shaft of the motor 15, the edge of the top side of the disc 14 and one end of the transmission rod 13 are connected by a bearing, a hinge or a rotating pin, the other end of the transmission rod 13 and one end of the gear rod 12 are connected by a bearing, a hinge or a rotating pin, the motor 15 is electrically connected to an external control switch, and the external control switch controls the rotation state of the motor 15.

[0032] The working process and principle of this embodiment are:

[0033] The operator opens the cover plate 4 on the opening of the circular shell 5, and the operator puts the additive liquid and solid samples into the inner cavity of the circular shell 5. The additive liquid is sterile saline, buffered peptone water or liquid culture medium. The operator snaps the cover plate 4 on the opening of the circular shell 5. The operator installs the circular shell 5 on the top of the rotating shaft 6. The central axis of the circular shell 5 coincides with the central axis of the rotating shaft 6. The operator controls the motor 15 to work, and the motor 15 drives the disc 14 to rotate. The edge of the top side of the disc 14 drives the gear rod 12 to reciprocate along its length direction through the transmission rod 13. The reciprocating gear rod 12 drives the rotation direction of the circular shell 5 to change periodically through the gear 10 and the rotating shaft 6.

[0034] After the rotation direction of the circular shell 5 changes, the rotation direction of the sphere 7 in the circular shell 5 is first opposite to the rotation direction of the circular shell 5, the friction between the sphere 7 and the sample reduces the angular velocity of the sphere 7, and then the rotation direction of the sphere 7 in the circular shell 5 is the same as the rotation direction of the circular shell 5, and the rotation angular velocity of the sphere 7 in the circular shell 5 gradually approaches the rotation angular velocity of the circular shell 5.

[0035] After the rotation direction of the circular shell 5 changes, the rotation direction of the sphere 7 in the circular shell 5 is first opposite to the rotation direction of the circular shell 5, and the sphere 7 and the sample move relatively. The sphere 7 continuously hits the sample to break the sample, and the sphere 7 squeezes the broken sample attached to the inner wall of the circular shell 5 to break the large particles in the broken sample. The sphere 7 continuously breaks up the broken sample to mix the sample evenly, thereby improving the homogenization effect of the sample.

[0036] Furthermore, when the sample is homogenized and the rotation speed of the circular shell 5 is the fastest, the size of the sample and the additive liquid in the circular shell 5 along the axial direction of the circular shell 5 is smaller than the radius of the sphere 7 .

[0037] Furthermore, the top end of the rotating shaft 6 and the middle position of the bottom side of the circular shell 5 are connected by a buckle or a pin.

[0038] Embodiment 2:

[0039] like Figure 6 As shown, this embodiment discloses a food and drug homogeneity detection equipment, and its structure is roughly the same as that of the first embodiment, except that the cover plate 4 of this embodiment is made of metal, the top side of the cover plate 4 is fixedly connected to the bottom end of the tube body 17, an opening and closing cover body 16 is installed on the top of the tube body 17, and a mounting hole connecting the inside and the outside of the circular shell 5 is opened on the top side, and a valve 18 is installed on the mounting hole.

[0040] The working process and principle of this embodiment are:

[0041] A cold source is placed in the tube body 17, and the cold source is ice cubes, dry ice or an ice-water mixture. The operator opens the valve 18, and the valve 18 is connected to the external negative pressure pump. The operator extracts the air in the inner cavity of the circular shell 5 through the external negative pressure pump to reduce the air pressure in the circular shell 5 to the set value, and then the operator closes the valve 18.

[0042] During the reciprocating rotation of the circular shell 5, the friction between the sphere 7 and the inner wall of the circular shell 5, the friction between the sphere 7 and the sample, and the friction between the sample and the inner wall of the circular shell 5 all generate heat, causing the sample temperature to rise. If the food and drug homogenization detection equipment of Example 1 homogenizes a heat-sensitive sample, it is easy to cause the heat-sensitive sample to denature.

[0043] In the second embodiment, the air pressure in the circular shell 5 is reduced to a set value so as to reduce the boiling point of the water in the circular shell 5 , and the maximum tolerable temperature of the heat-sensitive sample is higher than the boiling point of the water in the circular shell 5 .

[0044] The temperature of the thermosensitive sample rises to the boiling point of the water in the circular shell 5, the water in the thermosensitive sample evaporates and takes away the heat of the thermosensitive sample, the water vapor in the circular shell 5 contacts the bottom side of the cover body 16 and then condenses into water, and the condensed water continues to return to the thermosensitive sample, and the cold source in the tube body 17 condenses the water vapor in the circular shell 5 through the cover body 16, avoiding the saturation of the water vapor in the circular shell 5, thereby improving the reliability of temperature control of the thermosensitive sample.

[0045] Embodiment three:

[0046] like Figure 1 , 2 As shown, the present embodiment discloses a food and drug homogeneity detection device, and its structure is substantially the same as that of the second embodiment, except that a cover shell 2 is installed on the top side of the base 1 of the present embodiment, and the rotating shaft 6, the gear rod 12, the transmission rod 13, and the disc 14 are all located in the cover shell 2. The top end of the rotating shaft 6 passes through the cover shell 2 and extends to the top of the cover shell 2. The cover shell 2 encloses the gear rod 12, the transmission rod 13, and the disc 14 to prevent operators from contacting the gear rod 12, the transmission rod 13, and the disc 14 in a working state, thereby improving the safety of the food and drug homogeneity detection device.

[0047] Embodiment 4:

[0048] like Figure 1 , 2 As shown in Figures 6, this embodiment discloses a food and drug homogeneity detection device, the structure of which is substantially the same as that of the third embodiment, except that a circular tube 3 is installed on the top side of the cover shell 2 of this embodiment, the circular shell 5 is located in the inner cavity of the circular tube 3, and the outer diameter of the circular shell 5 is equal to the inner diameter of the circular tube 3.

[0049] During the reciprocating rotation of the circular shell 5, the sphere 7 makes it easy for the circular shell 5 to swing around the central axis of the circular shell 5, and the circular tube 3 limits the swing range of the circular shell 5, thereby improving the reliability of the food and drug homogeneity detection equipment.

[0050] Embodiment five:

[0052] The electric heating element 19 is electrically connected to an external control switch.

[0053] The motor 15 and the electric heating element 19 used in the present invention are all common electronic components in the prior art, and their working methods and circuit structures are all well-known technologies and will not be described in detail here.

[0054] The working process and principle of this embodiment are:

[0055] The operator turns on the electric heating element 19, and the heat generated by the electric heating element 19 is transferred to the circular shell 5 through the circular tube 3. The thermosensitive sample attached to the inner wall of the circular shell 5 is heated, and steam bubbles are generated between the thermosensitive sample and the inner wall of the circular shell 5. The steam bubbles reduce the adhesion between the thermosensitive sample and the inner wall of the circular shell 5, thereby improving the homogenization effect of the thermosensitive sample.

The operator inserts the guide rod 20 into the clamping hole of the cover plate 4 and the cover plate 4 is completely fitted on the opening of the circular shell 5, so that the cover plate 4 blocks the opening of the circular shell 5, and the cover plate 4 is convenient to open and close on the opening of the circular shell 5.

Based on any one of embodiments one to six, the inner diameter of the circular shell 5 of this embodiment gradually decreases from the middle to the top, and the inner diameter of the circular shell 5 gradually decreases from the middle to the bottom. During the rotation of the circular shell 5, the sample and the sphere 7 both move toward the middle of the inner wall of the circular shell 5, increasing the contact between the sphere 7 and the sample.

[0060] Embodiment eight:

[0062] When the sphere 7 passes through the protrusion 8, the protrusion 8 causes the sphere 7 to separate from the inner wall of the circular shell 5, and then the sphere 7 and the inner wall of the circular shell 5 contact each other again, and the sphere 7 collides with the sample on the inner wall of the circular shell 5, thereby improving the homogenization efficiency of the sample.

[0064] like Figure 2 , 4 As shown, this embodiment discloses a food and drug homogeneity detection device, and its structure is roughly the same as that of the first embodiment, except that, in this embodiment, the middle position of the bottom side of the circular shell 5 is fixedly connected to the top of the clamping rod 9, and a positioning slot adapted to the clamping rod 9 is provided at the top of the rotating shaft 6, and the clamping rod 9 is inserted into the positioning slot of the rotating shaft 6, thereby improving the convenience of connecting the circular shell 5 and the rotating shaft 6.
