Technical Field

The synthesis plate generally includes a plurality of channels distributed in an array, and each channel can be used for a separate synthesis process. The synthesis plate can be used in conjunction with a blow-press synthesizer. Specifically, after the reagent is added to the channel of the synthesis plate, the blowing synthesizer is controlled to contact the periphery of the synthesis plate by controlling the lifting part of the blowing synthesizer, thereby forming a sealed cavity above the synthesis plate. Then, the blowing part of the blowing synthesizer is controlled to blow air into the sealed cavity, and the reagent in the channel of the synthesis plate flows downward through the action of air pressure, so that the reagent flows through the channel of the synthesis plate, thereby achieving the purpose of synthesis.

[0003] However, since the synthesis reagents are volatile, the volatilized reagents may adhere to the inside of the blow-press synthesizer, causing blockage or corrosion of the lifting part of the blow-press synthesizer, thus affecting the service life of the blow-press synthesizer.

[0047] Please refer to Figure 1-Figure 9 The blowing mechanism for the synthesis plate 400 provided in the embodiment of the present application at least comprises a housing 100, a movable assembly 200 and a blowing assembly 300. The synthesis plate 400 comprises a synthesis area 410 and a blank area 420 located around the synthesis area 410. The synthesis area 410 is provided with a plurality of channels distributed in an array, for example, the channels can be arranged in the form of synthesis columns, each channel can be used for a separate synthesis reaction, and the blank area 420 surrounds the outer periphery of the synthesis area 410. Before using the blowing mechanism, the reagent needs to be injected into the channel on the synthesis area 410, and then the blowing mechanism is used to make the reagent pass through the channel on the synthesis area 410, thereby completing the biosynthesis reaction.

[0048] Specifically, the shell 100 forms the outer contour of the blowing mechanism, and the interior of the shell 100 has a cavity, which can be used to accommodate the movable component 200, the blowing component 300 and the composite plate 400.

[0049] The movable assembly 200 is disposed in the cavity and divides the cavity into a first cavity a and a second cavity b. The first cavity a and the second cavity b are not connected to each other, that is, the gas in the first cavity a cannot enter the second cavity b, and the gas in the second cavity b cannot enter the first cavity a. Among them, the second cavity b is used to accommodate the composite board 400. The movable assembly 200 is configured to be able to move relative to the composite board 400, so as to contact the blank area 420 of the composite board 400 and enclose the third cavity c with the composite board 400. At this time, the entrance of the channel on the composite area 410 of the composite board 400 is connected to the third cavity c.

[0050] The blowing assembly 300 is connected to the movable assembly 200, and the blowing assembly 300 is configured to supply gas to the third cavity c after the movable assembly 200 and the synthesis plate 400 enclose the third cavity c, so as to change the gas pressure in the third cavity c. For example, when gas is supplied to the third cavity c via the blowing assembly 300 to increase the gas pressure in the third cavity c, the gas in the third cavity c will pressurize the reagent in the hole through the entrance of the hole on the synthesis area 410 of the synthesis plate 400, so as to regulate the flow rate of the reagent flowing through the hole and make the reagent pass through the hole on the synthesis area 410, thereby completing the synthesis reaction.

[0051] Through the above-mentioned structural design, when the blowing mechanism is used to control the reagent to pass through the channels on the synthetic plate 400, it is first necessary to inject the reagent into the channels on the synthetic plate 400 in advance, and then place the synthetic plate 400 in the second cavity b of the blowing mechanism, and then control the movable component 200 to move toward the synthetic plate 400 so that the movable component 200 and the synthetic plate 400 form a third cavity c, and then use the blowing component 300 to supply air to the third cavity c so that the air pressure in the third cavity c changes, thereby controlling the speed of the reagent flowing through the channels on the synthetic plate 400 to achieve the synthesis purpose.

[0052] According to the blowing mechanism for the synthetic plate 400 provided in the present application, since the movable component 200 separates the first cavity a and the second cavity b, even if the corrosive reagent in the pores of the synthetic plate 400 located in the second cavity b evaporates, the volatilized reagent will not enter the first cavity a to cause blockage or corrosion to the shell 100 and the movable component 200 that surround the first cavity a, so that the movable component 200 can move stably in the cavity, which is beneficial to extend the service life of the blowing mechanism.

[0053] As a further preferred implementation scheme, based on the above scheme, the specific embodiments of the present application may also include one or more of the following additions or combinations.

[0054] In some optional embodiments, the shell 100 is provided with an air inlet 111 connected to the first cavity a, and the air inlet 111 is connected to an external air source such as a blower, etc., for supplying air into the first cavity a; the movable component 200 is configured to be pushed by the air pressure in the first cavity a and move toward the synthetic board 400 when air is supplied to the first cavity a through the air inlet 111, so as to contact the synthetic board 400 and enclose a third cavity c.

[0055] By supplying air to the first cavity a through the air inlet 111, the air pressure change in the first cavity a can drive the movable component 200 to move. Therefore, the movable component 200 can be used to effectively separate the cavity in the shell 100 into a first cavity a and a second cavity b that do not interfere with each other, and it is also beneficial to control the movement of the movable component 200 relative to the synthetic board 400 so as to contact the blank area 420 of the synthetic board 400 and enclose a third cavity c.

[0056] Furthermore, there may be multiple air inlets 111 , and the air supply efficiency can be improved by using multiple air inlets 111 to supply air into the first cavity a at the same time.

[0057] After the reagent passes through the holes on the synthesis plate 400, the first cavity a needs to be depressurized to cancel the thrust on the movable component 200, so that the movable component 200 is separated from the synthesis plate 400, and the synthesis plate 400 can be removed.

[0058] In some optional embodiments, the shell 100 is provided with an air outlet 112 connected to the first cavity a, and a valve or other components can be provided at the air outlet 112 to discharge the gas in the first cavity a through the air outlet 112 to relieve the pressure of the first cavity a.

[0059] It should be noted that in other optional embodiments, the first cavity a can also be directly depressurized through the air inlet 111, that is, the air inlet 111 is used for both supplying air to the first cavity a and exhausting the gas in the first cavity a. In this case, there is no need to set a separate air outlet 112.

[0060] In some optional embodiments, the shell 100 includes a first cover plate 110 and a second cover plate 120, which are connected to form a cavity, and the first cover plate 110 is provided with an air inlet 111; the movable component 200 and the first cover plate 110 form a first cavity a, and the movable component 200 and the second cover plate 120 form a second cavity b.

[0061] Reference Figure 1-Figure 3 , Figure 5-Figure 6 The first cover plate 110 is disposed above the second cover plate 120, and the two are connected by bolts or other parts to form a cavity. The movable assembly 200 can respectively form a first cavity a and a second cavity b with the first cover plate 110 and the second cover plate 120, so that the installation and removal operations of the movable assembly 200 and the first cover plate 110 and the second cover plate 120 are easier, which is conducive to improving the installation and removal efficiency of the blowing mechanism.

[0062] Further, in some optional embodiments, referring to Figure 7 The housing 100 further includes a sealing layer 130, for example, the sealing layer 130 may be a silicone pad. The sealing layer 130 is disposed between the first cover plate 110 and the second cover plate 120 to seal and connect the first cover plate 110 and the second cover plate 120, thereby facilitating the improvement of the sealing of the first cavity a enclosed by the movable assembly 200 and the first cover plate 110, and effectively avoiding the problem of air leakage in the first cavity a.

[0063] In some optional embodiments, the movable component 200 includes a connector 210 and a seal 220, one side of the connector 210 is connected to the first cover plate 110 and together they form a first cavity a, the other side of the connector 210 is connected to the seal 220 and together they form a second cavity b, the connector 210 and the seal 220 are used to form a third cavity c with the synthetic board 400; the blowing component 300 is connected to the connector 210 and / or the seal 220 for supplying air into the third cavity c.

[0064] Specifically, the connector 210 may be in a roughly flat plate-shaped structure, and the connector 210, together with the first cover plate 110 and the second cover plate 120, respectively, encloses a first cavity a and a second cavity b. When air is supplied into the first cavity a, the air pressure in the first cavity a may push the connector 210 to move toward the synthesis board 400 in the second cavity b. The seal 220 may be in a roughly frame-shaped structure, for example, the seal 220 may be a silicone pad. The seal 220 may move with the connector 210 to contact the blank area 420 of the synthesis board 400 and enclose a third cavity c, and the seal 220 may be used to improve the sealing of the third cavity c and avoid air leakage in the third cavity c, which is conducive to accurately supplying air into the third cavity c through the blowing assembly 300 to control the flow rate of the reagent flowing through the pores on the synthesis board 400, thereby helping the reagent to fully perform a synthesis reaction in the pores of the synthesis board 400.

[0065] In some optional embodiments, the sealing member 220 is provided with a plurality of opening portions 221, and the plurality of opening portions 221 are arranged at intervals, and each opening portion 221 is used to enclose a third cavity c with the connecting member 210 and a corresponding synthetic plate 400; the movable component 200 also includes a diverter 230, which is arranged between the connecting member 210 and the sealing member 220, and the diverter 230 is provided with an air inlet and a plurality of air outlets, the air inlet is connected to the blowing component 300, and each air outlet is connected to a corresponding third cavity c.

[0066] Reference Figure 8 and Fig. 9 The sealing member 220 is a rectangular frame structure formed by two openings 221, and the flow divider 230 is provided with an air inlet and two air outlets. The two openings 221 of the sealing member 220 can respectively enclose two third cavities c with two different synthesis plates 400, and the flow divider 230 is used to divide the gas from the blowing assembly 300 to the two third cavities c, so that the air pressure in the two third cavities c can be controlled at the same time, so as to realize the simultaneous control of the reagent flow rate in the channels on the two synthesis plates 400, which is conducive to improving the synthesis efficiency.

[0067] It should be understood that the two openings 221 shown in the figure are only examples, and the specific number of the openings 221 can be determined according to actual conditions, and the number of air outlets of the diverter 230 can be set corresponding to the number of the openings 221.

[0068] In some optional embodiments, the movable component 200 also includes an elastic member 240, which is arranged in the second cavity b between the connecting member 210 and the second cover plate 120, and the elastic member 240 is used to apply force to the connecting member 210 to make the connecting member 210 move in a direction away from the synthetic board 400.

[0069] Reference Figure 1-Figure 3, the elastic member 240 may be, for example, a spring, and the number of the elastic member 240 may be multiple, and the two ends of each spring are respectively connected to the connecting member 210 and the second cover plate 120. As air is supplied into the first cavity a, the connecting member 210 and the sealing member 220 of the movable assembly 200 may move to form a third cavity c with the composite plate 400. After a sufficient amount of gas is supplied into the third cavity c through the blowing assembly 300 to allow the reagent in the pores of the composite plate 400 to pass through the composite plate 400, the gas supplied into the first cavity a may be removed to reduce the air pressure in the first cavity a, and the thrust of the air pressure in the first cavity a on the connecting member 210 and the sealing member 220 is reduced. At this time, under the elastic force of the elastic member 240, the connecting member 210 and the sealing member 220 may move toward the direction of the first cavity a and disengage from the composite plate 400, thereby realizing the reset of the connecting member 210 and the sealing member 220, so as to facilitate the next blowing operation.

[0070] In some optional embodiments, the blowing assembly 300 includes an air inlet assembly 310 and an adapter 320, at least a portion of the air inlet assembly 310 is disposed in the first cavity a, and the adapter 320 is connected to the connector 210 and communicated with the air inlet assembly 310 to supply air to the third cavity c.

[0071] Optionally, the connector 210 is provided with a through hole 211 communicating with the third cavity c, the adapter 320 extends into the through hole 211 and is telescopically connected to the connector 210 via the through hole 211, and the sealing between the outer wall of the adapter 320 and the inner wall of the through hole 211 should be ensured to be good. The air intake assembly 310 and the adapter 320 are connected to the first cover plate 110, and when the connector 210 is pushed by the air pressure in the first cavity a to move toward the synthetic board 400, the connector 210 will also move relative to the adapter 320, and the depth of the corresponding connector 210 extending into the through hole 211 will be reduced. The air intake assembly 310 is connected to the connector 210 via the adapter 320 for communicating with the third cavity c, and at least a portion of the air intake assembly 310 is arranged in the first cavity a, so that the blowing assembly 300 is integrated with the housing 100, which is conducive to reducing the space occupied by the blowing mechanism.

[0073] Reference Figure 3The air inlet pipe 311 may be in an "L" shape, one end of the air inlet pipe 311 located outside the first cavity a is connected to an external air source such as a blower, and the other end of the air inlet pipe 311 located inside the first cavity a is connected to the adapter 320 via the connector 312, so that air can be effectively supplied to the third cavity c through the air inlet pipe 311. In addition, arranging part of the air inlet pipe 311 inside the first cavity a is conducive to improving the integration of the air inlet assembly 310 with the housing 100 and the movable assembly 200, so that a compact structure and a smaller volume blowing mechanism can be obtained.
