According to the embodiment of the invention, the culture medium preparation equipment is provided, and the problems that the components of the culture medium can not be ensured to be in a sterile state and the loss and denaturation of the components of the culture medium are easily caused in the prior art are solved.

Referring to fig. 1 and 2, the medium preparing apparatus includes a preparing chamber (not shown), a support member 13, a first magnetic member 7, a second magnetic member 1, and a first driving part 3. Wherein the support 13 is located in the preparation chamber, e.g. at the bottom of the preparation chamber, movable therein, and the support 13 is configured to place a receptacle containing the culture medium. The first magnetic part 7 is positioned in the preparation chamber and fixed at the bottom of the support part 13; the second magnetic part 1 is positioned outside the preparation chamber and is correspondingly arranged below the first magnetic part 7; the first driving part 3 is connected with the second magnetic part 1 and drives the second magnetic part 1 to move; the second magnetic part 1 moves to drive the first magnetic part 7 to move.

In the culture medium preparation device, the first magnetic part 7 and the second magnetic part 1 are respectively positioned inside and outside the preparation chamber, and the magnetic field is acted between the first magnetic part and the second magnetic part. Specifically, when the second magnetic member 1 moves, the first magnetic member 7 is moved by the action of the magnetic field. The first magnetic part 7 moves to drive the support part 13 to move, so that the culture medium in the accommodating body on the support part 13 is shaken to achieve the purpose of full mixing.

Moreover, the first magnetic part 7 and the second magnetic part 1 are respectively positioned inside and outside the preparation chamber and interact with each other through a magnetic field without direct contact, so that the problem of tightness caused by the transmission part passing through the preparation chamber can be avoided.

The second magnetic member 1 is located outside the preparation chamber and is correspondingly disposed below the first magnetic member 7, and the "corresponding disposition" refers to the following condition: the second magnetic member 1 is in the magnetic field of the first magnetic member 7, or the first magnetic member 7 is in the magnetic field of the second magnetic member 1, so that the first magnetic member 7 moves along with the second magnetic member 1 when the second magnetic member 1 moves.

The first magnetic member 7 refers to an object that reacts in some way to a magnetic field and does not require itself to be able to generate a magnetic field. The first magnetic member 7 can be made of any magnetic material, such as a magnet, low-carbon steel, etc.; of course, the first magnetic member 7 may be an energized coil. Similarly, the second magnetic member 1 may also be made of any magnetic material or be in the form of an electrified coil, and the specific form is not limited as long as the first magnetic member 7 can drive the second magnetic member 1 to move through a magnetic field.

Note that the movement modes of the first magnetic member 7 and the second magnetic member 1 are not limited. For example, the first driving part 3 can drive the second magnetic part 1 to rotate, and the second magnetic part 1 drives the first magnetic part 7 to rotate. For another example, the first driving part 3 can drive the second magnetic member 1 to move linearly, and the second magnetic member 1 drives the first magnetic member 7 to move linearly.

Under the condition that the first driving part 3 drives the second magnetic part 1 to rotate and the second magnetic part 1 drives the first magnetic part 7 to rotate: the medium formulating device further comprises a mounting 12, the mounting 12 being mounted to the floor of the formulating chamber such that the mounting 12 is located below the support 13.

Wherein, the mounting seat 12 can be connected with the supporting piece 13 through at least three eccentric wheels 8; one eccentric wheel 8 is connected with a first end of a rotating shaft 10, and a second end of the rotating shaft 10 penetrates through a mounting seat 12 and then is connected with a first magnetic piece 7; the first driving component 3 is a rotation driving component, the rotation driving component drives the second magnetic component 1 to rotate, and the second magnetic component 1 drives the first magnetic component 7 to rotate.

In the case of three eccentric wheels 8, a secure mounting of the support 13 on the mounting 12 is ensured. Of course, the number of the eccentric wheels 8 is not limited by the examples herein, for example, the eccentric wheels 8 may be four, five, etc.

Wherein, eccentric wheel 8 divide into action wheel and follow driving wheel, action wheel and follow driving wheel all with support piece 13 fixed connection. For the driving wheel, it is connected to the first end of the rotating shaft 10, and the second end of the rotating shaft 10 is connected to the first magnetic member 7 after passing through the mounting seat 12. For the driven wheel, the driven wheel is connected with a first end of a mounting shaft, a second end of the mounting shaft is fixed on the mounting base 12, and the driven wheel can rotate relative to the mounting shaft. Furthermore, when the first magnetic member 7 rotates, the rotating shaft 10 of the driving wheel drives the driving wheel to rotate, the driving wheel drives the supporting member 13 to rotate, and the supporting member 13 drives the driven wheel to rotate relative to the mounting shaft when rotating. When the support member 13 moves circularly in the plane, the medium components contained in the container body form a vortex, so that the different medium components are mixed sufficiently.

Wherein the gap between the driving wheel and the first magnetic element 7 is matched with the thickness of the mounting seat 12.

It should be noted that, of course, it is not necessary to provide the eccentric 8 between the supporting member 13 and the mounting base 12 in order to allow the supporting member 13 to rotate relative to the mounting base 12. For example, a connecting rod may be disposed between the supporting member 13 and the mounting seat 12, the first magnetic member 7 is fixedly connected to one end of the connecting rod, the other end of the connecting rod is connected to the supporting member 13, and then the first magnetic member 7 rotates to drive the connecting rod to rotate, and finally the supporting member 13 is driven to move along a circle. For another example, a cam may be provided between the supporting member 13 and the mounting seat 12, and the supporting member 13 may be driven to rotate by the cam.

It should furthermore be mentioned that the mounting 12 need not necessarily be provided, for example, in the case of the above-mentioned eccentric 8, the second end of the mounting shaft of the driven wheel can be directly fixed to the bottom plate of the preparation chamber, while the rotational axis 10 of the driving wheel is directly arranged at the bottom of the support 13.

When the second magnetic member 1 rotates, a rotating magnetic field is generated, and the rotating magnetic field generates closed magnetic lines of force through the first magnetic member 7, so that the magnetic force reaches the maximum, and the first magnetic member 7 rotates along with the magnetic field. The rotation of the first magnetic element 7 causes the support element 13 to move along a circle in a plane, so that the medium in the container forms a vortex, and the mixing of different medium components is accelerated.

Under the condition that the first driving part 3 drives the second magnetic part 1 to do linear motion and the second magnetic part 1 drives the first magnetic part 7 to do linear motion: the preparation chamber bottom plate is provided with a linear guide rail, and the support member 13 is mounted on the linear guide rail through a slide block and can linearly move along the linear guide rail. The sliding block and the first magnetic part 7 are fixed, and then when the second magnetic part 1 moves linearly, the second magnetic part 1 drives the first magnetic part 7 to move linearly, and the first magnetic part 7 drives the sliding block to move linearly.

Also, in order to allow the support member 13 to reciprocate in a straight line in the preparation chamber, the connection relationship between the support member 13 and the preparation chamber is not limited to the connection form of the guide rail and the slider, but may also take any construction form that has been disclosed in the prior art. For example, a rack and pinion connection between the support member 13 and the dosing chamber may also be used, in which case the rack is fixed to the bottom plate of the dosing chamber, the pinion is fixed to the first magnetic member 7, and the pinion is fixed to the support member 13.

Of course, the mounting base 12 may be provided in the preparation chamber, and the linear guide or the rack described above may be fixed to the mounting base 12.

It should be noted that, when the second magnetic member 1 drives the first magnetic member 7 to move linearly, the shaking effect of the first magnetic member is less than that of the second magnetic member 1, and the mixing effect of the culture medium is less than that of the second magnetic member 7.

Referring to fig. 4, when the mounting base 12 is disposed, the mounting base 12 is connected to a bottom plate (not shown) of the preparation chamber through the turning shaft 11, the mounting base 12 is disposed with a first limiting member, the preparation chamber is disposed with a second limiting member, and the first limiting member and the second limiting member are configured as follows: the first limiting piece and the second limiting piece are in limiting fit, and the mounting base 12 is locked on the bottom plate; the first limiting piece and the second limiting piece are relieved from limiting, and the mounting base 12 is forced to turn around the turning shaft 11.

In the process of mixing different culture medium components, the first limiting member and the second limiting member form limiting fit, the mounting base 12 is locked on the bottom plate, at the moment, the mounting base 12 is basically kept horizontal, and further the support member 13 on the mounting base 12 is kept in a horizontal state. After the mixing process is completed, in order to facilitate discharging the mixed culture medium from the preparation chamber, the first limiting member and the second limiting member are released, the mounting base 12 is turned around the turning shaft 11 under the action of external force, and the support member 13 and the accommodating body are tilted, so that the culture medium is conveniently discharged. Wherein, the external force applied to the mounting seat 12 generally refers to the gravity of the containing body and the culture medium therein.

The form of the mutual rotatable connection between the turning shaft 11 and the base plate can be regarded as a two-point connection. When the first limiting member and the second limiting member are in limiting fit, it can be seen that a three-point connection is formed between the mounting base 12 and the preparation chamber, so that the mounting base 12 is fixed on the bottom plate of the preparation chamber.

In particular, when the vessel is tilted, the gas in the medium does not escape with the solution, and a bubble-free medium can be obtained.

When the mounting base 12 is mounted in the preparation chamber, the first stopper is mounted at the rear side of the mounting base 12, that is, at the side away from the door body of the preparation chamber, and the turning shaft 11 is disposed along the width direction of the preparation chamber. Therefore, when the first limiting part and the second limiting part are relieved from limiting, the accommodating body and the culture medium in the accommodating body, which are arranged close to the preparation room door body, can generate the action of gravity on the front side of the support part 13, so that the front side of the support part 13 sinks and the back side of the support part tilts upwards.

Referring to fig. 4, the mounting base 12 is a supporting plate. The surface area of the mounting seat 12 may be set smaller than that of the supporting member 13, and particularly, only the mounting requirement of the supporting member 13 is met, so that the weight and the manufacturing cost of the mounting seat 12 can be reduced.

According to the embodiment of the invention, the first limiting member may be a plug 9 fixed at the bottom of the supporting plate, and the corresponding second limiting member may be a socket 14, and the socket 14 is connected to the second driving member and driven by the second driving member to move away from or to sleeve the plug 9.

Of course, the specific form of the first limiting member and the second limiting member is not limited herein, and any form of structure that can achieve limiting matching may be adopted. For example, the first limiting part and the second limiting part may also adopt mutually matched limiting pressing plates; for another example, a pin and a groove that mate with each other may also be used.

The second driving part can adopt a motor, a hydraulic cylinder, an air cylinder and the like.

Referring to fig. 1 and 2 again, the first driving member 3 is mounted on the guide rod 6, and the first driving member 3 is connected to the electric push rod 5 and moves along the axial direction of the guide rod 6 under the action of the electric push rod 5. Furthermore, after the culture medium mixing process is completed, the electric push rod 5 extends to drive the first driving part 3 and the second magnetic part 1 to be away from the first magnetic part 7, so that the acting force between the first magnetic part 7 and the second magnetic part 1 is minimized. Wherein, when the acting force between the first magnetic member 7 and the second magnetic member 1 is reduced, the overturning of the mounting seat 12 can be facilitated.

Of course, it should be noted that the electric push rod 5 may not be provided, and at this time, only the position of the turning shaft 11 needs to be reasonably designed, please refer to fig. 6 and 7, so that the weight of the front part close to the turning shaft 11 is greater than the weight of the rear part, and when the first limiting member and the second limiting member are unlocked, the magnetic attraction between the first magnetic member 7 and the second magnetic member 1 can be overcome, so as to realize the turning and tilting of the mounting base 12.

According to an embodiment of the present invention, referring to fig. 5, the first driving member 3 is a driving motor, the driving motor is connected to the magnet base 4 through the speed reducing member 2, the second magnetic member 1 is a magnet fixed to the magnet base 4, and the magnet includes magnet blocks respectively disposed at two sides of the magnet base 4; the first magnetic member 7 is a magnetic conductive plate. In this case, the output shaft of the first driving member 3 rotates, and the rotational motion is transmitted to the magnet holder 4 through the speed reduction member 2, and the magnet holder 4 rotates the second magnetic member 1.

Of course, the specific manner of the first driving part 3 is not limited by the examples herein, and it can adopt any form disclosed in the prior art, and as long as it can drive the first magnetic part 7 to move.

In fig. 4, the supporting member 13 is a net bracket. By using the net-like bracket, not only can the weight be reduced and the driving of the supporting member 13 be ensured, but also the accommodating body can be more sufficiently exposed. Of course, the specific structural form of the supporting member 13 is not limited as long as the supporting requirement of the accommodating body is satisfied.

According to the embodiment of the invention, the preparation chamber is a temperature control chamber, and the temperature of the culture medium is adjusted by adjusting the temperature of the temperature control chamber. It should be noted that when the supporting member 13 is a net-shaped bracket, it can ensure the accommodating body to be in more sufficient contact with air, and further ensure that the accommodating body has better temperature adjusting effect.

Since the components of the culture medium can be classified into a coagulant, a nutrient and an additive, any one of a coagulant solution, a nutrient solution and an additive solution can be contained in the container. Wherein the coagulant solution is obtained by mixing coagulant and water according to a set proportion. Similarly, the nutrient solution is obtained by mixing a nutrient and water according to a set proportion; the additive solution is obtained by mixing an additive and water according to a set proportion.

Under the premise, the corresponding culture medium can be prepared by only mixing at least two of the coagulant solution, the nutrient solution and the additive solution.

Sterile bags can be selected for the packaging bag, so that the components of the culture medium can be stored in a sterile environment. Moreover, the packaging bag is preferably selected from soft packaging bags, so that the packaging bag is convenient to transport and store.

Wherein, since most of the culture medium needs the coagulant solution, and the coagulant solution generally needs to go through the heating process and the cooling process in sequence, the first package containing the coagulant solution is placed on the support 13, so that the first package is located in the temperature controlled chamber. And the second package body is positioned outside the temperature control chamber.

The preparation process of the nutrient comprises the following steps: firstly, heating the coagulant solution in the first packaging body to enable the coagulant solution to reach a set temperature; introducing the nutrient solution and/or the additive solution in the second package into the first package; driving the second magnetic part 1 to drive the first magnetic part 7, the support part 13 and the first package body to move, so that the culture medium components in the first package body are fully shaken and mixed; the medium was cooled.

Wherein, the installation component can be the mounting groove that sets up outside the temperature control chamber, also can be for fixing the installing support at the temperature control chamber lateral wall, and specific structural style is unrestricted, as long as can satisfy the installation of second packing body can. When the second packaging body is provided with the hanging hole, the mounting part can also be a hook positioned outside the temperature control chamber.

Further, the culture medium preparation equipment also comprises a first communication pipe, and the first communication pipe is used for introducing components in the second packaging body at the mounting part into the first packaging body in the temperature control chamber. The first communicating pipe is connected with an electric control pump, and the electric control pump pumps the components in the second packaging body into the first packaging body under the control of the controller.

Further, pipe joints are arranged at two ends of the first communication pipe, and the pipe joints are correspondingly arranged on the first packaging body and the second packaging body, so that the first communication pipe and the packaging bodies (including the first packaging body and the second packaging body) are connected. The pipe joint can realize the sealing connection between first connecting pipe and the packing body to can guarantee the quick assembly disassembly between first connecting pipe and the packing body.

The first end of first connecting pipe is located inside the temperature control room, and then when placing first packing body into the middle of the temperature control room, can realize being connected between first packing body and the first connecting pipe. The second end of the first communication pipe is located outside the temperature control chamber and located at the installation part, and therefore when the second packaging body is installed on the installation part, the second packaging body and the first communication pipe can be connected.
