Heating mechanism, liquid chamber module and liquid material extrusion device Technical Field

[0001] This invention relates to a heating mechanism, a liquid chamber module, and a liquid material extrusion device, and more particularly to a heating mechanism, a liquid chamber module, and a liquid material extrusion device capable of heating liquid materials. Prior Technology

[0002] Patent No. I716866, "Liquid Chamber Module of Liquid Extrusion Device," discloses a liquid chamber module of a liquid extrusion device, comprising: a heating mechanism having a housing and a heat-conducting mold; the heat-conducting mold, a first chamber thereon, and a placement area adjacent to the first chamber are all disposed within the housing; the placement area has a heater electrically connected to a circuit board; a liquid chamber mechanism disposed within the first chamber of the heating mechanism, the liquid chamber mechanism having a connector for guiding liquid material from a liquid storage cylinder outside the liquid chamber module into the liquid chamber mechanism; the liquid chamber mechanism having a plunger, and an elastic member providing a restoring driving force for the plunger; the plunger having a head and a rod portion, the lower end of which is located in a liquid chamber of the liquid chamber mechanism, and can push the liquid material in the liquid chamber, causing the liquid material in the liquid chamber to be extruded from a valve nozzle.

[0003] In patent number I716866, since the liquid chamber mechanism can be independently disassembled or assembled from the heating mechanism, there will be a gap between the inner wall of the first chamber and the outer wall of the liquid chamber mechanism, making the liquid chamber mechanism easy to disassemble and assemble. However, the existence of the gap also makes it difficult for the heat energy of the heating mechanism to be transferred to the liquid chamber mechanism, resulting in heating results that do not meet expectations. In addition, in patent number I716866, the heat generated by the heat-conducting mold can also easily damage the circuit board. It can be seen that there are still areas for improvement in the prior art. Summary of the Invention

The liquid material extrusion device is equipped with an actuation module A, and a liquid chamber module B is located below the actuation module A. The actuation module A is equipped with a quick-release mechanism C, which has a switch C1. The switch C1 can operate a fastener C2 located on the left and right sides of the actuation module A (only the fastener C2 on the right side is shown in the figure) to latch or release the liquid chamber module B, so that the liquid chamber module B can be selectively engaged with the actuation module A or disassembled from the actuation module A.

[0014] Please refer to Figures 2 and 3. The liquid chamber module B is equipped with a heating mechanism D and a liquid chamber mechanism E. The heating mechanism D is used to heat the liquid chamber mechanism E. In this embodiment, the actuation module A may be, for example, a combination of a piezoelectric actuator and a lever, and the liquid chamber mechanism E may be, for example, a combination of a liquid supply channel, a liquid chamber, a valve, and a plunger. The liquid material in the liquid supply cylinder may be input into the liquid chamber through the liquid supply channel. The piezoelectric actuator may drive the lever to move the plunger up and down, thereby squeezing the liquid material in the liquid chamber out through the valve. Since the actuation module A and the liquid chamber mechanism E are not features claimed in this application, their detailed structures will not be described in detail below.

[0015] Please refer to Figures 3, 4, and 5. The heating mechanism D is provided with a heating base D1. The heating base D1 is provided with a chamber D11 for housing the liquid chamber mechanism E, a first main slit D12 communicating with the chamber D11, and a second main slit D13 communicating with the chamber D11. The chamber D11 is provided with a first section D111 and a second section D112. The first section D111 is located above the first main slit D12 and the upper side of the first section D111 is hollowed out. The second section D112 is located between the first main slit D12 and the second main slit D13, and the upper and lower sides of the second section D112 are hollowed out. The first main slit D12 and the second main slit D13 are respectively disposed on the front and rear sides of the second interval D112. The length of the first main slit D12 is greater than the length of the second main slit D13. The first main slit D12 and the second main slit D13 extend along a horizontal first direction d1. The heating base D1 is also provided with a first slit D14 and a second slit D15 on the left and right sides of the second main slit D13, and the first slit D14 and the second slit D15 are mirror-oriented with the second main slit D13 as the boundary; The first slit D14 has a first outer segment D141, a first middle segment D142, and a first inner segment D143. The first outer segment D141 and the first inner segment D143 are spaced apart and parallel to each other in the first direction d1 and extend along a second direction d2. The first middle segment D142 connects the first outer segment D141 and the first inner segment D143. One end of the first middle segment D142 is connected to one end of the first outer segment D141, and the other end of the first middle segment D142 is connected to one end of the first inner segment D143. The first middle segment D142 extends along a third direction d3. The second slit D15 has a second outer section D151, a second middle section D152, and a second inner section D153. The second outer section D151 and the second inner section D153 are spaced apart and parallel to each other in the first direction d1 and extend along the second direction d2. The second middle section D152 connects the second outer section D151 and the second inner section D153. One end of the second middle section D152 is connected to one end of the second outer section D151, and the other end of the second middle section D152 is connected to one end of the second inner section D153. The second middle section D152 extends along a fourth direction d4. The first main slit D12, the second main slit D13, the first slit D14, and the second slit D15 are hollowed out on their upper and lower sides. One end of the first main slit D12, the first slit D14, and the second slit D15 is connected to the peripheral side of the heating seat D1. The first slit D14 and the second slit D15 are not connected to the chamber D11. The first direction d1, the second direction d2, the third direction d3, and the fourth direction d4 are horizontal and intersect each other. The first direction d1 and the second direction d2 are orthogonal. The angle between the third direction d3 and the fourth direction d4 and the first direction d1 is an acute angle.

[0016] Please refer to Figures 3 and 4. The heating mechanism D is provided with a housing D2, which has an outer shell D21 located on the lower side and a cover D22 located on the upper side. The outer casing D21 is rectangular in shape and has a receiving area D211 for accommodating the heating base D1. The heating base D1 can be accommodated in the receiving area D211 of the outer casing D21, and the outer casing D21 prevents the heat of the heating base D1 from being transferred to the surroundings and the lower side or protects the heating base D1 from direct touch by the operator. The outer casing D21 has a cutout D212 communicating with the receiving area D211, and the cutout D212 corresponds to the second section D112 of the receiving chamber D11. The cover D22 is rectangular and has a third section D221 corresponding to the outline of the chamber D11. The heating seat D1 can be accommodated in the accommodating section D211 and covered by the cover D22. The cover D22 can be fixed above the heating seat D1 by, for example, a plurality of fasteners D23 with screws. The cover D22 can prevent the heat of the heating seat D1 from being transferred upward to the actuation module A (Figure 2).

[0017] Please refer to Figures 5, 6, and 7. The heating base D1 is provided with a first adjusting part D16 and a second adjusting part D17 on the left and right sides of the chamber D11, which can clamp the liquid chamber mechanism E (Figure 3), and a fixing part D18 is provided on the rear side of the chamber D11. The first adjusting part D16 and the second adjusting part D17 are separated by the chamber D11, the first main slit D12, and the second main slit D13. The first adjusting part D16 and the fixing part D18 are separated by the first slit D14 but still connected. The second adjusting part D17 and the fixing part D18 are separated by the second slit D15 but still connected. The first main slit D12, the second main slit D13, the first slit D14, and the second slit D15 provide space for the chamber D11 to deform slightly. The fixing part D18 can accommodate a control circuit board D3. The first adjustment part D16 and the second adjustment part D17 can be adjusted by an adjustment assembly D19; the adjustment assembly D19 is provided with a bolt D191 that can pass through the first main slit D12 and a nut D192 that can be screwed on one end of the bolt D191; the adjustment assembly D19 is also provided with an elastic member D193 that can pass through the first main slit D12, and the elastic member D193 can support between the first adjustment part D16 and the second adjustment part D17.

[0018] Please refer to Figures 5, 6, and 7. The heating mechanism D (Figure 3) includes a heating element D4 and a temperature sensing element D5 on the heating base D1. The heating element D4 and the temperature sensing element D5 are electrically connected to the control circuit board D3. The heating element D4 has two heating rods D41, which can be installed in the heating base D1 and are located on the left and right sides of the chamber D11. Specifically, the two heating rods D41 are respectively installed in the first adjustment part D16 and the second adjustment part D17. The temperature sensing element D5 has two temperature sensors D51. The two temperature sensors D51 can be installed in the heating base D1 and located on the left and right sides of the chamber D11. Specifically, the two temperature sensors D51 are respectively installed in the first adjustment part D16 and the second adjustment part D17, so that the first adjustment part D16 and the second adjustment part D17 can generate heat. The first slit D14 and the second slit D15 also have the effect of reducing the heat generated by the first adjustment part D16 and the second adjustment part D17 to the fixing part D18, which can reduce the possibility of the control circuit board D3 being damaged by heat.

[0019] In this embodiment, the operator can place the liquid chamber mechanism E in the chamber D11 of the heating base D1 of the heating mechanism D, and adjust the adjusting component D19 to tighten the bolt D191 and the nut D192, thereby reducing the distance between the first adjusting part D16 and the second adjusting part D17 of the heating base D1. This allows the liquid chamber mechanism E in the chamber D11 to be sandwiched between the first adjusting part D16 and the second adjusting part D17 from the left and right sides, reducing the clearance between the liquid chamber mechanism E and the heating mechanism D, and making it easier for the heat generated by the heating base D1 to be transferred to the liquid chamber mechanism. At this time, the elastic member D193 between the first adjusting part D16 and the second adjusting part D17 accumulates elastic restoring force. After the liquid chamber mechanism E is placed in the chamber D11, the operator can operate the quick-release mechanism C to connect the liquid chamber module B of the liquid extrusion device with the actuation module A and perform the liquid extrusion operation; After the liquid material extrusion device has been performing liquid material extrusion operations for a period of time, the operator can operate the quick-release mechanism C to disassemble the liquid chamber module B of the liquid material extrusion device from the actuation module A for maintenance or cleaning; After the liquid chamber module B is disassembled from the actuation module A, the operator can adjust the adjustment component D19 to loosen the bolt D191 and the nut D192, thereby widening the gap between the first adjustment part D16 and the second adjustment part D17 of the heating base D1, releasing the clamping of the first adjustment part D16 and the second adjustment part D17 on the liquid chamber mechanism E, and using the elastic restoring force of the elastic member D193 to open the first adjustment part D16 and the second adjustment part D17, so as to restore the clearance between the liquid chamber mechanism E and the heating mechanism D, making it easy to disassemble or reassemble the liquid chamber mechanism E from the heating mechanism D; The adjustment component D19 allows the operator to actively adjust the distance between the first adjustment part D16 and the second adjustment part D17 of the heating seat D1. However, the heating seat D1 may also be without the adjustment component D19. When the horizontal width of the liquid chamber mechanism E is slightly larger than the horizontal width of the container D11, the distance between the first adjustment part D16 and the second adjustment part D17 will also expand along the contour of the peripheral side of the liquid chamber mechanism E and fit tightly with the liquid chamber mechanism E during the process of the liquid chamber mechanism E being placed into the container D11.

[0020] The heating mechanism, liquid chamber module, and liquid material extrusion device of this embodiment can reduce the clearance between the heating base D1 and the liquid chamber mechanism E by having the first adjustment part D16 and the second adjustment part D17 of the heating base D1 clamp and accommodate the liquid chamber mechanism E in the chamber D11, thereby making it easier for the heat generated by the heating base D1 to be transferred to the liquid chamber mechanism E. In addition, the first slit D14 and the second slit D15 also have the effect of reducing the heat generated by the first adjustment part D16 and the second adjustment part D17 to be transferred to the fixing part D18, thereby reducing the possibility of the control circuit board D3 being damaged by heat.

[0021] However, the above description is only a preferred embodiment of this invention and should not be construed as limiting the scope of this invention. Any simple equivalent changes and modifications made in accordance with the scope of the patent application and the description of this invention shall still fall within the scope of this invention.
