The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other with other embodiments.

[0030] Embodiment 1

[0031] Referring to Figures 1 to 7 , this is the first embodiment of the present invention. This embodiment provides a device for manufacturing a microfluidic chip with a three-dimensional flow channel. The device for manufacturing a microfluidic chip with a three-dimensional flow channel includes a main body component 100 and an adjustment component 200. The adjustment component 200 calibrates and adjusts the main body component 100 to make it stable for placement.

[0032] A device for manufacturing a microfluidic chip with a three-dimensional flow channel, which includes a main body component 100. The main body component 100 includes a device body 101, and the device body 101 is a 3D printer for manufacturing a microfluidic chip with a three-dimensional flow channel.

[0033] The adjusting assembly 200 is arranged at the bottom of the device body 101 and includes a base 201, a support plate 202, a rotating member 203, a pushing member 204, a triggering member 205, a blocking member 206 and a moving member 207. The base 201 is arranged at the bottom of the device body 101. The support plate 202 is located inside the base 201. The rotating member 203 is arranged inside the base 201. The pushing member 204 is located inside the rotating member 203. The triggering member 205 is arranged inside the base 201. The blocking member 206 is located on one side of the pushing member 204. The moving member 207 is located on one side of the blocking member 206.

[0034] The device body 101 is connected to the top of the support plate 202. The support plate 202 is used to support the device body 101. Through the arrangement of the rotating member 203, it is used to adjust the angle of the support plate 202 and drive the device body 101 to move through the support plate 202, so that the device body 101 can be adjusted to a horizontal state. Through the arrangement of the pushing member 204, when the support plate 202 is tilted, it indicates that the device body 101 is not in a horizontal state. At this time, the pushing member 204 pushes the downward-tilted side of the support plate 202 upward, so that the device body 101 can be restored to a horizontal state. Through the arrangement of the triggering member 205, when the base 201 is tilted, the triggering member 205 will drive the pushing member 204 to move, so that the pushing member 204 can drive the support plate 202 to move. Through the arrangement of the blocking member 206, it is used to position the pushing member 204 so that the pushing member 204 can be locked after pushing the device body 101 to a horizontal state. At this time, the device body 101 can be supported by the pushing member 204, so as to avoid the situation that the angle of the device body 101 is tilted due to the vibration during use. Through the arrangement of the moving member 207, it is used to drive the blocking member 206 to move, so that the blocking member 206 can lock and unlock the pushing member 204.

[0035] Embodiment 2

[0036] Refer to Figures 1 to 7 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment.

[0037] Specifically, the rotating member 203 includes a support sleeve 203a, a positioning sleeve 203b, a rotating ball 203c and a fixing column 203d. The support sleeve 203a is fixed inside the base 201. The positioning sleeve 203b is located inside the support sleeve 203a. The rotating ball 203c is fixed to the bottom of the support plate 202. The two ends of the fixing column 203d are respectively fixed to the support sleeve 203a and the positioning sleeve 203b.

[0038] The rotating ball 203c is movably connected inside the positioning sleeve 203b. There are multiple fixing columns 203d, which are evenly distributed on the outer side of the positioning sleeve 203b. The fixing columns 203d are used to connect and fix the positioning sleeve 203b to the support sleeve 203a to prevent the positioning sleeve 203b from falling off. Through the settings of the positioning sleeve 203b and the rotating ball 203c, they are used to cooperate with the support plate 202 for rotation, enabling the support plate 202 to rotate at any angle of 360°.

[0039] Specifically, the pushing member 204 includes a push column 204a, a fixing plate 204b, and a first spring 204c. A slot Z is formed inside the support sleeve 203a. The push column 204a is inserted into the slot Z. The fixing plate 204b is fixed to the outer side of the push column 204a. The first spring 204c is fixed to the bottom of the fixing plate 204b and sleeved on the outer side of the push column 204a.

[0040] There are multiple groups of the pushing members 204, which are evenly distributed in a ring inside the support sleeve 203a. Through the settings of the multiple groups of pushing members 204, the support plate 202 can be pushed to move at any position of 360°. The top end of the push column 204a contacts the support plate 202. Through the setting of the push column 204a, when the support plate 202 is not in a horizontal state, it is used to push the lower side of the support plate 202 to move upward, so that the support plate 202 can be restored to the horizontal state. An accommodation chamber is formed inside the slot Z. The bottom end of the first spring 204c is fixed to the inner wall of the accommodation chamber. The fixing plate 204b is used to fix the first spring 204c. Through the setting of the first spring 204c, an upward thrust is applied to the fixing plate 204b and the push column 204a, enabling the push column 204a to always contact the support plate 202. At the same time, when the push column 204a does not need to push the support plate 202, it can also drive it to reset to the initial position. The fixing plate 204b is located at the center of the accommodation chamber, so that the push column 204a can move up and down.

[0041] Specifically, the pushing member 204 further includes a push block 204d and a connecting rod 204e. The push block 204d is located on one side of the push column 204a. The connecting rod 204e is fixed to one side of the push block 204d. A corresponding slot X is formed on the push column 204a opposite to the push block 204d.

[0042] One side of the push block 204d is inclined. When the inclined surface of the push block 204d presses against the inner wall of the slot X, the push column 204a can be driven to move through their cooperation, so that the push column 204a can push the support plate 202 to move. A through groove is formed inside the support sleeve 203a. The connecting rod 204e is movably connected inside the through groove. The connecting rod 204e is used to drive the push block 204d to move, so that the push block 204d can press against the inner wall of the slot X.

[0043] Specifically, the trigger member 205 includes a fixing sleeve 205a, a sensing ball 205b and a positioning rod 205c. The fixing sleeve 205a is located in the supporting sleeve 203a, the sensing ball 205b is disposed in the fixing sleeve 205a, and the positioning rod 205c is fixed to the bottom of the fixing sleeve 205a.

[0044] The sensing ball 205b has a certain weight. The outer side of the fixing sleeve 205a is in contact with multiple connecting rods 204e. When the base 201 is placed on the desktop and tilted, the sensing ball 205b will move in the corresponding tilt direction and drive the fixing sleeve 205a to move, so that the fixing sleeve 205a can push the connecting rod 204e to move, and the connecting rod 204e can drive the push block 204d to move. The positioning rod 205c is L-shaped and there are multiple of them. They are fixed in a ring shape at the bottom of the fixing sleeve 205a. A positioning groove is provided in the support sleeve 203a. The positioning rod 205c is movably connected to the positioning groove. The positioning rod 205c cooperates with the positioning groove to position the fixing sleeve 205a to prevent it from tilting during movement, which makes it unable to push the connecting rod 204e to move.

[0045] Specifically, the sealing member 206 includes a movable frame 206a, a sealing ball 206b, a sealing ring 206c and a second spring 206d. A movable groove V is opened in the support sleeve 203a, the movable frame 206a is located in the movable groove V, a groove N is opened on the movable frame 206a, the sealing ball 206b is located in the groove N, the sealing ring 206c is fixed to the bottom of the push column 204a, and the two ends of the second spring 206d are respectively fixed to the sealing ball 206b and the inner wall of the groove N.

[0046] The slot Z is connected to the movable slot V, the diameter of the sealing ball 206b is larger than the slot Z, and the number of the sealing balls 206b corresponds to the slot Z. When the sealing ball 206b is engaged with the bottom end of the slot Z, a fully enclosed space is formed between the bottom of the push post 204a and the top of the sealing ball 206b. At this time, the push post 204a will be locked by the enclosed chamber. When the push post 204a moves upward, the enclosed chamber forms a negative pressure, which will restrict the push post 204a from moving upward. When the push post 204a moves upward, the pressure in the enclosed chamber increases, which also restricts the push post 204a, so that the push post 204a cannot move up and down. Move, and at this time, when the support plate 202 is supported by the push column 204a, the support plate 202 can be prevented from tilting. The sealing ring 206c is used to improve the sealing between the push column 204a and the slot Z to avoid air pressure leakage. The second spring 206d is set to apply an upward thrust to the sealing ball 206b, so that the sealing ball 206b and the slot Z are more tightly engaged to avoid loosening of the two, thereby causing air pressure leakage. The diameter of the movable groove V is larger than the movable frame 206a, and the movable frame 206a can move horizontally in the movable groove V.

[0047] Example 3

[0048] Reference Figures 1 to 7 , which is the third embodiment of the present invention. This embodiment is based on the first two embodiments.

[0049] Specifically, the moving member 207 includes a fixed rod 207a, a movable sleeve 207b, and a fixed shaft 207c. One end of the fixed rod 207a is fixed to the movable frame 206a. One end of the movable sleeve 207b is rotatably connected to the inner wall of the base 201. The fixed shaft 207c is fixed within the movable sleeve 207b. A spiral groove S is formed on the fixed rod 207a, and the fixed shaft 207c slides within the spiral groove S.

[0050] One end of the fixed rod 207a extends to the outside of the support sleeve 203a and is movably connected to the support sleeve 203a. One side of the movable sleeve 207b is rotatably connected to the inner wall of the base 201 through a bearing. When the movable sleeve 207b rotates, it will drive the fixed shaft 207c to slide within the spiral groove S. Through the cooperation of the two, the fixed rod 207a can be driven to move, and the movable frame 206a can be driven to move by the fixed rod 207a, so that the movable frame 206a drives the sealing ball 206b to engage and separate from the slot Z, thereby releasing the restriction on the push rod 204a and enabling the push rod 204a to move freely up and down. When the movable sleeve 207b rotates in the reverse direction, it will drive the fixed rod 207a and the movable frame 206a to move in the reverse direction, and the sealing ball 206b will engage with the slot Z again.

[0051] Specifically, the moving member 207 further includes a gear 207d, a toothed plate 207e, a connecting block 207f, and a moving block 207g. The gear 207d is fixed to the outside of the movable sleeve 207b. The toothed plate 207e is located on one side of the gear 207d. One side of the connecting block 207f is fixed to the toothed plate 207e. The moving block 207g is fixed to the other side of the connecting block 207f.

[0052] A chute is formed on the base 201. The connecting block 207f is slidably connected within the chute. The gear 207d meshes with the toothed plate 207e. When the toothed plate 207e moves upward, it will drive the gear 207d to rotate, thereby enabling the gear 207d to drive the movable sleeve 207b to rotate. When the toothed plate 207e moves downward, the gear 207d and the movable sleeve 207b can be driven to rotate in the reverse direction. The moving block 207g is L-shaped and is located outside the base 201. Through the arrangement of the moving block 207g, it is convenient for the user to drive the toothed plate 207e to move upward.

[0053] Specifically, the moving member 207 further includes a support rod 207h and a counterweight 207i. The support rod 207h is fixed to the top of the toothed plate 207e. The counterweight 207i is fixed to the top of the support rod 207h.

[0054] The support rod 207h is U-shaped and is used to support and fix the counterweight 207i. By setting the counterweight 207i, it is used to drive the toothed plate 207e to move downward, so that without the interference of human external force, the toothed plate 207e can drive the gear 207d and the movable sleeve 207b to rotate in the reverse direction. A guide block is fixed on the counterweight 207i, and a guide groove (not shown in the figure) is provided on the inner wall of the base 201. The guide block slides in the guide groove. Through the cooperation of the two, it is used to position the counterweight 207i to prevent it from tilting during movement.

[0055] Specifically, the moving member 207 further includes a positioning cylinder 207j, a positioning column 207k, and a sealing plate 207l. The positioning cylinder 207j is fixed in the base 201. One end of the positioning column 207k is fixed to the support rod 207h, and the sealing plate 207l is fixed to the other end of the positioning column 207k.

[0056] The sealing plate 207l is movably connected inside the positioning cylinder 207j. A very small-diameter air vent is provided at the bottom of the positioning cylinder 207j. When the counterweight 207i drives the toothed plate 207e to move downward, the sealing plate 207l will simultaneously move downward inside the positioning cylinder 207j. Since the air vent at the bottom of the positioning cylinder 207j is small, the sealing plate 207l moves slowly downward inside the positioning cylinder 207j, so that the toothed plate 207e can drive the gear 207d and the movable sleeve 207b to rotate slowly in the reverse direction. In this way, the sealing ball 206b can be delayed in engaging with the slot Z, so that the push column 204a can have enough time to drag the support plate 202 to the horizontal state. When the support plate 202 moves to the horizontal state, the sealing ball 206b can engage with the slot Z, so as to lock the push column 204a.

[0057] The device has two states. The first state: when the sealing ball 206b is separated from the slot Z, at this time, the support plate 202 can tilt at any angle to complete the horizontal calibration of the equipment body 101.

[0058] The second state: when the sealing ball 206b is engaged with the slot Z, at this time, the push column 204a cannot move up and down, so the support plate 202 can be supported and positioned by the push column 204a, and the support plate 202 cannot tilt, thus avoiding the situation that the equipment body 101 tilts during use.

[0059] During use, when the base 201 is placed on the desktop and has a certain inclination, causing the device body 101 not to be in a horizontal state, pull the moving block 207g upward to drive the toothed plate 207e to move upward. When the toothed plate 207e moves upward, it drives the gear 207d to rotate, causing the gear 207d to drive the movable sleeve 207b to rotate. When the movable sleeve 207b rotates, it drives the fixed shaft 207c to slide in the spiral groove S. Through the cooperation of the two, the fixed rod 207a can be driven to move, and the movable frame 206a is driven to move by the fixed rod 207a, so that the movable frame 206a drives the sealing ball 206b to engage and separate from the slot Z, thereby releasing the restriction on the push column 204a. At this time, the sensing ball 205b will move in the corresponding inclined direction and drive the fixed sleeve 205a to move. The connecting rod 204e is pushed to move by the fixed sleeve 205a, and the connecting rod 204e drives the push block 204d to move. When the inclined surface of the push block 204d presses against the inner wall of the card slot X, the push column 204a can be driven to move through the cooperation of the two, and the support plate 202 is pushed by the push column 204a, so that the support plate 202 can be moved to a horizontal state and drive the device body 101 to a horizontal state.

[0060] Meanwhile, when the counterweight 207i drives the toothed plate 207e to move downward, the sealing plate 207l will simultaneously move downward in the positioning cylinder 207j. Since the ventilation holes at the bottom of the positioning cylinder 207j are relatively small, the sealing plate 207l slowly moves downward in the positioning cylinder 207j, so that the toothed plate 207e can drive the gear 207d and the movable sleeve 207b to rotate slowly in the reverse direction, so that the sealing ball 206b can be delayed to engage with the slot Z. When the sealing ball 206b engages with the bottom end of the slot Z, a completely enclosed space is formed between the bottom of the push column 204a and the upper part of the sealing ball 206b. At this time, the push column 204a will be locked by the enclosed chamber, making the push column 204a unable to move up and down. At this time, the support plate 202 can be supported by the push column 204a, so as to avoid the device body 101 from tilting. Since the inclination angle of the desktop is not too large, only the angle of the device body 101 needs to be finely adjusted.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
