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 can be controlled to start and drive the lever module 42 downward, so that the lever module 42 drives the valve body 33 downward to spray the contained liquid material through the valve nozzle 331. Since the liquid material extruding means 4 for driving the valve 33 to eject the liquid material is of various types, the present invention is not limited to the above embodiment.

Referring to fig. 3, 4 and 5, the clutch mechanism 5 includes a latching switch 6 installed on the main body 2 and detachably connected to the liquid chamber seat 3, a releasing latching switch 7 disposed on the latching switch 6, and a clutch switch 8 disposed on the main body 2.

The locking switch 6 comprises two clasps 61 arranged in the main body 2 at intervals in front and back and protruding downwards from the bottom end of the main body 2 to be clamped on the liquid chamber base 3, a transmission module 62 arranged in the main body 2 and connected between the clasps 61, a pushing module 63 arranged on the left narrow side 21 of the main body 2 and connected with the transmission module 62, a first elastic member 64 elastically connected between the middle sections of the clasps 61, a push rod 65 bridging between the top ends of the clasps 61, and a second elastic member 66 elastically supported between the main body 2 and the push rod 65 in an up-and-down mode.

Each of the clasps 61 has a slot 611 formed through the top end thereof and extending vertically, and a clasp hole 612 formed through the bottom end thereof and exposed below the main body 2. The two bottom ends of the buckle handle 61 protruding out of the lower portion of the main body 2 are clamped in the seat body 311 in opposite directions, and are buckled on the buckle protrusions 312 through the buckle holes 612. The first elastic member 64 has an elastic force for urging the catcher 61 to clip the liquid chamber holder 3 forward and backward, and the second elastic member 66 has an elastic force for urging the catcher 61 downward with respect to the main body 2.

The transmission module 62 is located in the installation space 23, and includes a shaft pin 621 disposed between the handles 61 and inserted into the slot 611 of the handle 61 in a front-back axial manner, a first connecting member 623 rotatably sleeved outside the shaft pin 621 at a top end thereof, a fixing pin 624 fixed to the main body 2 in a front-back axial manner, a second connecting member 625 rotatably sleeved outside the fixing pin 624 at a bottom end thereof, a movable pin 626 extending in a front-back axial direction and rotatably pivoted between the bottom end of the first connecting member 623 and the top end of the second connecting member 625, and an elastic body 627 elastically abutting against the main body 2 and the movable pin 626 in a left-right direction. And the transmission module 62 can be transmitted by the pushing module 63 to change between an extended state and a bent state, so as to respectively transmit the buckling handle 61 to drive the liquid chamber seat 3 to close and separate from the main body 2.

The pivot pin 621 has two insertion ends 622 that are axially displaceably inserted into the elongated slots 611 of the holder 61, respectively. Each plugging end 622 is upwardly limited to abut against the top edge of the corresponding long slot 611, and the upper and lower radial cut diameters thereof are smaller than the upper and lower lengths of the corresponding long slot 611. The elastic body 627 applies a spring force to the movable pin 626 in a leftward direction.

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 leans to the right against the inner wall 24, and elastically contracts the elastic body 627, and the first connecting element 623 and the second connecting element 625 are in an up-down vertical extended state slightly inclined to the left. At this time, the handle 61 is driven by the driving module 62 to drive the liquid chamber seat 3 to close upward and position under the main body 2.

When the transmission module 62 changes from the extended state to the bent state (as shown in fig. 6), the movable pin 626 is pushed leftwards away from the inner wall 24 by the elastic body 627, and the first connecting element 623 and the second connecting element 625 are linked to pivot left and right to form an inverted V shape with an opening extending obliquely left and right, since the fixing pin 624 is fixed on the main body 2, the movable pin 626 will move the shaft pin 621 downwards relative to the main body 2 via the first connecting member 623, and at the same time, the second elastic member 66 also elastically pushes the handle 61 downward relative to the main body 2, so as to drive the handle 61 to move downward relative to the main body 2, so that the handle 61 drives the liquid chamber base 3 to move downward and separate from the main body 2, however, the clasps 61 are still respectively clasped on the clasping convex parts 312 of the liquid chamber base 3, so that the liquid chamber base 3 does not directly fall down (as shown in fig. 7).

The pushing module 63 is disposed on the narrow side 21 of the left side of the main body 2, and includes a pressing lever 631 extending vertically and pivotally connected to the main body 2 at the bottom end thereof in the front-rear axial direction, and a pushing member 632 pivotally connected to the pressing lever 631 in the front-rear axial direction and protruding to the right to be radially inserted into the movable pin 626. The push handle 631 is operable to change between a locked position against the narrow side 21 and an unlocked position swinging outwardly away from the narrow side 21. The pushing element 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 inserting shaft 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 pivots from the locked position to the unlocked position (as shown in fig. 6), the pressing handle 631 drives the pushing component 632 to swing to the left, at this time, the elastic body 627 of the transmission module 62 elastically pushes the movable pin 626 to the left with respect to the main body 2, and the second elastic body 627 elastically pushes the pin 621 downwards via the buckle 61, so that the transmission module 62 changes 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 installed between the latch 71 and the pressing handle 631. The engaging member 71 has a pressing portion 711 located at the left side of the axis, and a hook-shaped engaging portion 712 located at the right side of the axis. 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 latching portion 712 of the latching member 71 to swing downward relative to the pressing handle 631.

When the pressing handle 631 is located at the locking position, the latching portion 712 of the latching member 71 is driven by the elastic driving member 72 to swing downward to latch the latching 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 latch 71 is pressed, the latch 71 pivots relative to the pressing lever 631, so as to drive the latch 712 to swing upward away from the latching edge 25, and at this time, the pressing lever 631 can be pushed leftward by the driving module 62 to swing to the unlocking position.

Referring to fig. 5, 9 and 10, the clutch switch 8 includes a fixing seat 81 disposed on the left side of the main body 2 of the narrow side 21, two pressing members 82 installed on the fixing seat 81 at intervals in the front-rear direction, two supporting members 83 pivoted on the main body 2 in a horizontal cross manner and abutting against the 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 fixed seat 81 is spaced below the pressing module 63, and has a guide groove 810 extending forward and backward, and the pressing members 82 are fitted in the guide groove 810, exposed to the wide side surfaces 22 of the main body 2, and capable of being pressed forward and backward to be displaced along the guide groove 810 in opposite directions. Each top support member 83 has a pressing portion 831 abutting against the corresponding pressing member 82, and an expanding portion 832 for abutting against the corresponding buckle handle 61, and the torsion elastic member 84 applies a torsion elastic force to the top support member 83 to drive the top support member 83 to swing back and forth against the pressing member 82 through the pressing portion 831.

Referring to fig. 10, 11 and 12, when the pressing member 82 is pushed and moved forward and backward, the pressing member 82 drives the pressing portion 831 of the supporting member 83 to pivot forward and backward, so that the supporting portion 832 of the supporting member 83 pivots outward back and forth, and pushes the handle 61 back and forth, so that the handle 61 swings back and forth relative to the shaft pin 621 (shown in fig. 5) to separate from the latching protrusion 312 of the liquid chamber 3, thereby releasing the liquid chamber 3.

Referring to fig. 2, 7 and 8, the method for separating the main body 2 from the liquid chamber seat 3 of the liquid material extruding apparatus 100 of the present invention is to press the latch 71 of the unlocking switch 7 to disengage the latch 71 from the latching 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 member 66 also pushes the latch 61 and the shaft pin 621 downward, so as to change the transmission module 62 from the extended state to the bent state, and push the pushing member 632 to the left with respect to the main body 2, so as to pivot the pressing handle 631 of the locking switch 6 to the unlocked position, and in addition, the latch 61 is also driven by the transmission module 62 to move downward with respect to the main body 2, and drive the seat 3 to disengage the main body 2 downward, so as to unlock the closed state.

Referring to fig. 10 and 12, next, the pushing element 82 of the clutch switch 8 is operated to drive the supporting element 83 to push and swing the handle 61 away from the snap projection 312 of the liquid chamber seat 3, so as to complete the disassembly of the main body 2 and the liquid chamber seat 3.

Referring to fig. 2, 11 and 13, when liquid chamber holder 3 is to be remounted to main body 2 after cleaning and maintenance, push-out slope 313 of snap projection 312 of liquid chamber holder 3 is aligned upward with the bottom end of handle 61, and liquid chamber holder 3 is pushed upward relative to handle 61. The push-out slope 313 forces the handle 61 to open back and forth, and when the catch protrusions 312 move up to align with the catch holes 612 of the handle 61, the first elastic member 64 drives the handle 61 to swing back and forth to clamp the catch 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 member 632 to drive the transmission module 62 to change to the extended state, and drive the buckle 61 to drive the liquid chamber base 3 to be closed upward below the main body 2. Then, the engaging member 71 of the unlocking switch 7 is engaged with the main body 2, and the liquid chamber holder 3 and the main body 2 are closed.

In summary, by the structural design of the locking switch 6 on the narrow side 21 of the main body 2 and the unlocking switch 7 on the locking switch 6, the mechanism for controlling whether the liquid chamber seat 3 is closed on the narrow side 21 of the main body 2 can be integrated on the narrow side 21 of the main body 2, and the locking switch 6 can be operated by one hand to drive the latch handle 61 to close the liquid chamber seat 3 on the main body 2 and the unlocking switch 7 can be operated by one hand to drive the pressing handle 631 of the locking switch 6 to change to the unlocking position, so that the latch handle 61 is driven to drive the liquid chamber seat 3 to be separated from the main body 2 downwards, and the liquid chamber seat 3 is still clamped between the latch handles 61 without being immediately separated and falling, and the clutch switch 8 can be operated by one hand to drive the latch handle 61 to release the liquid chamber seat 3 subsequently. Therefore, the liquid material extruding apparatus 100 of the present invention is really a very innovative creation, and the object of the present invention can be achieved.

However, the above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and all simple equivalent changes and modifications made according to the claims and the contents of the patent specification are still included in the scope of the present invention.
