The liquid chamber seat 3 comprises a seat body 31, a connecting piece 32 arranged on the seat body 31 and used for being connected with the liquid storage cylinder in a communicating way, and a valve body 33 arranged on the seat body 31 and used for containing liquid materials in a communicating way by the connecting piece 32, wherein the valve body 33 is provided with a valve nozzle 331 which is exposed on the bottom surface of the seat body 31 and used for ejecting the liquid materials downwards. The seat 31 includes a seat body portion 311 that is abutted upward against the bottom of the main body 2, and two engaging protrusions 312 that are respectively protruded from the front and rear sides of the seat body portion 311. Each of the latching projections 312 has an outward pushing inclined surface 313 extending obliquely upward and downward away from the seat body 311.
In the present embodiment, the liquid material extruding mechanism 4 includes a piezoelectric actuator 41 and a lever module 42 provided in the main body 2. The piezoelectric actuator 41 is controlled to be activated to drive the lever module 42 downwards, so that the lever module 42 drives the valve body 33 downwards to spray the contained liquid material through the valve nozzle 331. The type of the liquid material extruding mechanism 4 for driving the valve body 33 to eject is not limited to the above embodiment.
Referring to fig. 3, 4 and 5, the clutch mechanism 5 includes a latch switch 6 mounted on the main body 2 and detachably connected to the liquid chamber seat 3, a latch release switch 7 disposed on the latch switch 6, and a clutch switch 8 disposed on the main body 2.
The latch switch 6 includes two latch handles 61 disposed in the main body 2 at intervals in front and rear and protruding downward from the bottom end of the main body 2 to be clamped to the liquid chamber holder 3, a transmission module 62 installed in the main body 2 and coupled between the latch handles 61, a pressing module 63 installed at the left side of the main body 2 and coupled to the transmission module 62, a first elastic member 64 elastically coupled between the middle sections of the latch handles 61, a push rod 65 bridging between the top ends of the latch handles 61, and a second elastic member 66 elastically supported up and down between the main body 2 and the push rod 65.
Each knob 61 has a long slot hole 611 penetrating through the top end portion thereof and extending up and down, and a knob hole 612 penetrating through the bottom end portion thereof and exposed below the main body 2. The two bottom ends of the handle 61 protruding below the main body 2 are clamped to the seat body 311 in the front-back direction, and are respectively fastened to the fastening protrusions 312 through the fastening holes 612. The first elastic member 64 has an elastic force for urging the buckling handle 61 to clamp the liquid chamber seat 3 in front and back directions, and the second elastic member 66 has an elastic force for urging the buckling handle 61 downward elastically with respect to the main body 2.
The transmission module 62 is located in the installation space 23, and includes a shaft pin 621 interposed between the fastening handles 61 and axially inserted in the long slot 611 of the fastening handles 61 in the front-rear direction, a first connecting member 623 rotatably sleeved outside the shaft pin 621 at the top end portion thereof, a fixing pin 624 axially fixed on the main body 2 in the front-rear direction, a second connecting member 625 rotatably sleeved outside the fixing pin 624 at the bottom end portion thereof, a movable pin 626 axially extending in the front-rear direction and rotatably pivoted between the bottom end portion of the first connecting member 623 and the top end portion of the second connecting member 625, and an elastic body 627 elastically abutting between the main body 2 and the movable pin 626 in the left-right direction. And the transmission module 62 can be transmitted by the pushing module 63 to change between an extending state and a bending state, so as to respectively transmit the buckling handle 61 to drive the liquid chamber seat 3 to be closed and separated from the main body 2.
The shaft pin 621 has two insertion ends 622 axially displaceably inserted in the elongated holes 611 of the knob 61, respectively. Each of the plugging ends 622 is limited and abuts against the top edge of the corresponding long slot 611, and the vertical cross-sectional diameter thereof is smaller than the vertical length of the corresponding long slot 611. The elastic body 627 applies a left elastic pushing force to the movable pin 626.
Referring to fig. 3, 6 and 7, when the transmission module 62 is in the extended state (as shown in fig. 3), the movable pin 626 is leaning right against the inner wall 24, so as to elastically retract the elastic body 627, and the first connecting piece 623 and the second connecting piece 625 are in a slightly left-leaning vertical extending shape. At this time, the handle 61 is driven by the driving module 62 to drive the liquid chamber seat 3 to be closed and positioned below the main body 2.
When the transmission module 62 changes from the extended state to the meandering state (as shown in fig. 6), the movable pin 626 is pushed by the elastic body 627 to the left and away from the inner wall 24, and the first connecting piece 623 and the second connecting piece 625 are pivoted to the left and the second connecting piece 625 to form an inverted V shape with the opening extending obliquely upward and downward toward the left, and the fixing pin 624 is fixed on the main body 2, so that the movable pin 626 drives the shaft pin 621 to move downward relative to the main body 2 via the first connecting piece 623, and at the same time, the second elastic piece 66 also elastically pushes the buckling handle 61 downward relative to the main body 2, so as to drive the buckling handle 61 to move downward relative to the main body 2, so that the buckling handle 61 drives the liquid chamber seat 3 to move downward and separate from the main body 2, but the buckling handle 61 still respectively clamps the buckling protrusions 312 of the liquid chamber seat 3, so that the liquid chamber seat 3 cannot directly drop downward (as shown in fig. 7).
The pressing module 63 is a narrow side 21 disposed on the left side of the main body 2, and includes a pressing handle 631 extending vertically and axially pivoted to the main body 2 from the bottom thereof, and a pressing member 632 axially pivoted to the pressing handle 631 from front to back and projecting to the right and radially inserted into the movable pin 626. The lever 631 is operable to change between a latched position against the narrow side 21 and an unlatched position swung outwardly away from the narrow side 21. The pushing member 632 has a pivot end 633 pivotally connected to the pressing handle 631, a pushing portion 634 extending from the pivot end 633 to the right into the mounting space 23 and pushing against the movable pin 626, and an insertion portion 635 extending from the end of the pushing portion 634 to the right and radially penetrating the movable pin 626.
When the pressing handle 631 is in the locking position (as shown in fig. 3), the pressing handle 631 drives the pushing member 632 to push the movable pin 626 of the transmission module 62 to the right, so as to force the transmission module 62 to be positioned in the extended state. When the pressing handle 631 is pivoted from the locking position to the unlocking position (as shown in fig. 6), the pressing handle 631 drives the pushing element 632 to swing leftwards, at this time, the elastic body 627 of the transmission module 62 elastically pushes the movable pin 626 leftwards relative to the main body 2, and the second elastic body 627 elastically pushes the shaft pin 621 downwards via the buckling handle 61, so that the transmission module 62 is changed from the extended state to the bent state.
Referring to fig. 3, 6 and 8, the unlocking switch 7 has a latch 71 pivotally connected to the pressing handle 631 in a front-rear axial direction and spaced above the pushing member 632, and an elastic driving member 72 mounted between the latch 71 and the pressing handle 631. The locking member 71 has a pressing portion 711 located on the left side of the axis thereof, and a hook-shaped locking portion 712 located on the right side of the axis thereof. The elastic driving member 72 is elastically supported between the pressing portion 711 and the pressing handle 631, and has an elastic force for driving the locking portion 712 of the locking member 71 to pivot downward relative to the pressing handle 631.
When the pressing handle 631 is located at the locking position, the locking portion 712 of the locking member 71 is driven by the elastic driving member 72 to pivot downward to lock the locking edge 25 of the main body 2, so that the pressing handle 631 is located at the locking position. When the pressing portion 711 of the locking member 71 is pressed, the locking member 71 pivots relative to the pressing handle 631, and the locking portion 712 is driven to swing upwards away from the locking edge 25, and at this time, the pressing handle 631 can be pushed leftwards by the driving module 62 to pivot to change to the unlocking position.
Referring to fig. 5, 9 and 10, the clutch switch 8 includes a fixed seat 81 disposed on the left side of the main body 2, two pressing members 82 mounted on the fixed seat 81 at intervals, two supporting members 83 horizontally crossing each other and pivoted on the main body 2 and abutting against opposite sides of the pressing members 82, and a torsion elastic member 84 disposed between the main body 2 and the supporting members 83.
The fixing seat 81 is located below the pressing module 63 at intervals, and has a guide groove 810 extending forward and backward, and the pressing member 82 is embedded in the guide groove 810 and is respectively exposed on the wide side 22 of the main body 2, and can be pressed forward and backward to be displaced along the guide groove 810. Each supporting member 83 has a pressing portion 831 for abutting against the corresponding pressing member 82, and an expanding portion 832 for abutting against the corresponding fastening handle 61, and the torsion elastic member 84 applies a torsion elastic force to the supporting member 83 to urge the supporting member 83 to swing back and forth against the pressing member 82 with the pressing portion 831.
Referring to fig. 10, 11 and 12, when the pressing member 82 is pushed and moved in the front-back direction, the pressing member 82 drives the pressing portion 831 of the top support 83 to pivot in the front-back direction, so that the expanding portion 832 of the top support 83 swings and expands in the front-back direction, and pushes the handle 61 in the front-back direction, so as to drive the handle 61 to swing in the front-back direction relative to the shaft pin 621 (shown in fig. 5), and separate from the fastening protrusion 312 of the liquid chamber seat 3, thereby releasing the liquid chamber seat 3.
Referring to fig. 2, 7 and 8, in the method for separating the main body 2 from the liquid chamber seat 3 of the liquid material extruding device 100 according to the present invention, the locking piece 71 of the unlocking switch 7 is pressed to drive the locking piece 71 to separate from the locking edge 25 of the main body 2, at this time, the elastic body 627 of the transmission module 62 pushes the movable pin 626 to the left, the second elastic piece 66 pushes the locking handle 61 and the shaft pin 621 downwards, so as to drive the transmission module 62 to change from the extended state to the tortuous state, push the pushing piece 632 to the left with respect to the main body 2, and drive the pressing handle 631 of the locking switch 6 to pivot to the unlocking position, in addition, the locking handle 61 is driven by the transmission module 62 to move downwards with respect to the main body 2, and drive the liquid chamber seat 3 to separate from the main body 2 downwards, so as to release the closed state.
Referring to fig. 10 and 12, the pressing member 82 of the clutch switch 8 is operated to drive the top support member 83 to push the handle 61 away from the protruding portion 312 of the liquid chamber 3, so as to disassemble the main body 2 and the liquid chamber 3.
Referring to fig. 2, 11 and 13, when the cleaned and maintained liquid chamber seat 3 is to be reinstalled on the main body 2, the push-out inclined surface 313 of the fastening convex portion 312 of the liquid chamber seat 3 is directed upward to the bottom end of the fastening handle 61, and the liquid chamber seat 3 is pushed upward relative to the fastening handle 61. The push-out inclined surface 313 forces the handles 61 to be spread back and forth, and when the fastening protrusions 312 move up to align with the fastening holes 612 of the handles 61, the first elastic member 64 drives the handles 61 to swing back and forth in opposite directions to fasten the fastening protrusions 312 of the liquid chamber holder 3.
Then, the pressing handle 631 is pushed to pivot to the locking position, so as to drive the pushing piece 632 to drive the transmission module 62 to change to the extended state, and drive the knob 61 to drive the liquid chamber seat 3 to be closed up below the main body 2. Then, the locking piece 71 of the unlocking switch 7 is hooked and positioned on the main body 2, and the liquid chamber seat 3 and the main body 2 are closed and positioned.
In summary, by providing the locking switch 6 on the narrow side 21 of the main body 2 and providing the unlocking switch 7 on the locking switch 6, the mechanism for controlling whether the liquid chamber seat 3 is closed on the main body 2 can be integrally provided on the narrow side 21 of the main body 2, and the locking switch 6 can be conveniently operated by one hand to drive the knob 61 to close the liquid chamber seat 3 on the main body 2, and the pressing handle 631 of the locking switch 6 can be operated by one hand to drive the knob 61 to move to the unlocking position, so that the knob 61 can drive the liquid chamber seat 3 to separate from the main body 2 downwards, and the liquid chamber seat 3 can still be clamped between the knob 61 without falling off immediately, thereby facilitating the subsequent operation of the clutch switch 8 by one hand to drive the knob 61 to release the liquid chamber seat 3. Therefore, the liquid material extruding device 100 of the present invention is very innovative, and the purpose of the present invention can be achieved.
