[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0031] As Figure 1 shown, this embodiment provides a liquid seasoning storage device, including: a material bucket body 42, a bucket cover 43, and a liquid seasoning discharging unit 44. Among them, a liquid material cavity 420 for storing liquid seasoning is formed inside the material bucket body 42. Two buckles 421 are also provided at the rear of the material bucket body 42. When the liquid seasoning storage device is placed vertically in the corresponding installation position, the two buckles 421 can cooperate with the engaging columns on both sides of the installation position to achieve the detachable installation of the liquid seasoning storage device. The top of the material bucket body 42 is open, and the bucket cover 43 is pivotally connected to the opening at the top to facilitate opening or closing the opening at the top, thereby facilitating feeding into the material cavity. A sealing strip is also installed between the bucket cover 43 and the opening.

[0032] The bucket lid 43 can also assist the liquid seasoning storage device where it is located to be detachably connected to the corresponding installation position. The bucket lid 43 includes: a bucket lid body 431, a handle switch 432, and a compensation adjustment assembly 433. The bucket lid body 431 is pivotally connected to the opening at the top of the material bucket body 42, and the locking and opening of the bucket lid body 431 can be achieved through a door lock. The handle switch 432 is used to assist the detachable locking of the liquid seasoning storage device, and it is pivotally connected to the bucket lid body 431 through the compensation adjustment assembly 433.

[0033] As Figure 2 , 3 shown, the handle switch 432 includes: a first handle 344, a second handle 345, and a locking spring 346. The first handle 344 and the second handle 345 are cross - arranged, and the intersection position of the two is pivotally connected to the bucket lid body 431 through the compensation adjustment assembly 433. A through - hole is provided in the middle of any one of the handles. A lock catch 347 is provided on the outer side of one end of the handle, and a limit protrusion 348 is provided on the inner side; the other end of the handle forms a grip suitable for operation. The cross - arranged first handle 344 and second handle 345 are centrosymmetrically arranged, and the compensation adjustment assembly 433 passes through the through - hole in the middle of the two and is connected to the bucket lid body 431. The locking spring 346 is arranged between one ends of the first handle 344 and the second handle 345 and cooperates with the limit protrusions 348 of the two handles. In this way, under the pressure of the locking spring 346, the lock catches 347 of the first handle 344 and the second handle 345 can be fitted into the corresponding slots of the lock groove unit 161 at the installation position, so that the first handle 344 and the second handle 345 are in a locked state; and when the grips at the other end are controlled to pivot the first handle 344 and the second handle 345 to compress the locking spring 346, the first handle 344 and the second handle 345 can be in an unlocked state, thereby facilitating lifting the liquid seasoning storage device from the installation position where it is located to achieve the disassembly, installation, and replacement of the liquid seasoning storage device.

[0034] While realizing the pivotal connection of the handle switch 432, the compensation adjustment assembly 433 can also compensate for the matching error between the handle switch 432 and the lock groove unit 161, so as to overcome the problem that the lock catch 347 of the handle switch 432 is too high to match the lock groove unit 161, or although the handle switch 432 can match the lock groove unit 161, there is a problem of up - and - down shaking.

[0035] The compensation adjustment assembly 433 includes: an adjustment screw 349, a nut 350, a bushing 351, a snap ring 352, a gasket 353, a corrugated gasket, and a spring 355. Among them, the adjustment screw 349 is arranged on the barrel cover body 431 through the screw 28 seat. One end of the adjustment screw 349 has a nut, and the other end is screwed with the nut 350 located in the barrel cover body 431. The first handle 344 and the second handle 345 arranged crosswise are pivotally connected to the adjustment screw 349 through the bushing 351, and the first handle 344 and the second handle 345 cooperate with the ribs protruding from the bushing 351. In this way, when the adjustment screw 349 is rotated, the heights of the first handle 344 and the second handle 345 relative to the notch of the locking groove unit 161 can be finely adjusted through the bushing 351, thereby compensating for the assembly error between the first handle 344 and the second handle 345 and the locking groove unit 161.

[0036] The snap ring 352, the gasket 353, and the corrugated gasket are used to compensate for the assembly gap between the first handle 344 and the second handle 345 and the screw 28 seat. Specifically, the snap ring 352, the gasket 353, and the corrugated gasket are stacked and sleeved on the bushing 351 from top to bottom. The snap ring 352 is a C-shaped spring piece. The gasket 353 and the corrugated gasket are an O-shaped gasket 353, and the size of the gasket 353 is larger than that of the corrugated gasket. The corrugated gasket can provide axial tension. In addition, in order to prevent the first handle 344 and the second handle 345 from moving, the spring 355 is arranged between the first handle 344 and the second handle 345 and the barrel cover body 431, and presses the first handle 344 and the second handle 345 against the corrugated gasket.

[0037] As Figure 4 shown, the bottom 4201 of the liquid material cavity 420 has a discharge port. The liquid seasoning discharge unit 44 is arranged below the material barrel body 42 and is arranged opposite to the corresponding discharge port to realize the quantitative discharge of the liquid seasoning under the drive of the pushing mechanism 50. In addition, when the liquid seasoning in the liquid material cavity 420 is less, especially for relatively viscous liquid seasonings (such as oyster sauce, sauce, etc.), the problem of liquid seasoning sticking to the wall is likely to occur. At this time, in order to facilitate the full flow of the liquid seasoning, the discharge port is opened at the edge position of the bottom 4201 of the liquid material cavity 420 where it is located. And the bottom surface of the liquid material cavity 420 is inclined towards the direction of the discharge port. In this way, it is beneficial for the liquid seasoning to gather towards the discharge port, thereby facilitating the discharge of the liquid seasoning.

[0038] As Figure 5 、 6 shown, the liquid seasoning discharge unit 44 includes: a liquid storage cylinder 441, an outer end cover 442, a front end cover 443, a rear end cover 444, a piston rod 445, a liquid outlet nozzle 446, and an anti-drip structure 447.

[0039] Among them, the outer end cover 442 is connected to the front end cover 443, the front end cover 443 is connected to the front end of the liquid storage cylinder 441, and the rear end cover 444 is connected to the rear end of the liquid storage cylinder 441. The front end cover 443 is hollowly arranged and has a first liquid inlet 448, a second liquid inlet 449, a second liquid outlet 450 and a connection port 451 that are connected to the inside. The size of the internal space of the front end cover 443 can be set according to requirements.

[0040] The front end cover 443 is communicated with the discharge port at the bottom of the liquid material cavity 420 through its first liquid inlet 448, and is communicated with the liquid storage cylinder 441 through its second liquid inlet 449 and the second liquid outlet 450. In one embodiment, there are multiple second liquid inlets 449, and the multiple second liquid inlets 449 are circumferentially spaced around the second liquid outlet 450. One end of the liquid outlet nozzle 446 extends from the connection port 451 into the front end cover 443 and is oppositely arranged with the second liquid outlet 450.

[0041] In addition, in order to avoid liquid leakage, valve structures 453 are respectively arranged in the connection channel 452 between the front end cover 443 and the discharge port at the bottom of the liquid material cavity 420 and in the liquid outlet nozzle 446 on the front end cover 443. Specifically, the valve structure 453 includes a ball valve and a spring. For the valve structure 453 in the connection channel 452, its ball valve initially abuts against and closes the above-mentioned discharge port under the action of the spring. And a first sealing ring is also arranged between the ball valve and the discharge port. For the valve structure 453 in the discharge nozzle, its ball valve initially abuts against and closes the second liquid outlet 450 under the action of the spring. And a second sealing ring is also arranged between the ball valve and the second liquid outlet 450.

[0042] One end of the piston rod 445 is slidably arranged in the liquid storage cylinder 441 and is attached to the inner wall of the liquid storage cylinder 441 through the rubber plug on it. The other end of the piston rod 445 extends out of the rear end cover 444.

[0043] In this way, when the piston rod 445 is pulled out, under the action of negative pressure, the ball valve closing the discharge port opens, and the liquid seasoning in the bin is sucked into the front end cover 443 through the first liquid inlet 448. At the same time, under the action of the spring, the second liquid outlet 450 is always closed by the corresponding ball valve. Further, the liquid seasoning entering the front end cover 443 enters the liquid storage cylinder 441 through the second liquid inlet 449.

[0044] When the piston rod 445 is pushed reversely, the ball valve closes the discharge port again under the action of the spring, and the liquid seasoning in the liquid storage cylinder 441 flows into the liquid outlet nozzle 446 through the second liquid outlet 450 under the action of pressure and flows out through the liquid outlet nozzle 446. When the piston rod 445 moves to the initial position, the ball valve closes the second liquid outlet 450 again under the action of the spring. Thus, liquid leakage can be avoided when the discharge port and the second liquid outlet 450 are closed.

[0045] As described above, the liquid seasoning is drawn out by the piston rod 445 under negative pressure. Considering that when the liquid seasoning is relatively viscous and the stock is small, the liquid seasoning at the edge of the discharge port cannot be smoothly drawn out. Therefore, a filter screen 423 with a closed top and perforations around is also provided at the discharge port. In this way, when the piston rod 445 is pulled out, the filter screen 423 can suck the liquid seasoning through the perforations 424 around, thereby overcoming the problem that the viscous liquid seasoning accumulates around the discharge port and cannot flow out smoothly.

[0046] In addition, in order to ensure close contact between the first liquid inlet 448 and the discharge port, the bottom of the connection channel 452 is locked to the lower part of the liquid drum 41 through a gasket 4521. At the same time, considering that the continuous pulling of the piston rod 445 will affect the sealing performance between the first liquid inlet 448 and the discharge port. An elastic member 4522 is also provided between the connection channel 452 and the gasket 4521, and the elastic member 4522 is in a compressed state. In this way, the elastic member 4522 can compensate for the possible gap between the first liquid inlet 448 and the discharge port, so that the two continuously maintain close contact.

[0047] Considering that there may be some residual liquid seasoning in the liquid outlet nozzle 446 after liquid discharge, in order to prevent the liquid outlet nozzle 446 from dripping, the liquid outlet nozzle 446 is pivotally connected to the connection port 451 where it is located and is initially set upward. And when it can discharge liquid, it is driven by the anti-dripping structure 447 to pivot downward, and after the liquid discharge is completed, it is returned to the initial position by the anti-dripping structure 447.

[0048] Specifically, the liquid outlet nozzle 446 includes: a liquid outlet pipe 4461 and a nozzle 4462 connected to one end of the liquid outlet pipe 4461. Among them, the liquid outlet pipe 4461 is pivotally arranged on the front end cover 443 through the connection port 451, and the part of the liquid outlet pipe 4461 located on the front end cover 443 is axially limited by a gasket. One end of the liquid outlet pipe 4461 extends out of the front end cover 443 and the outer end cover 442, and the nozzle 4462 is vertically connected to the extended end of the liquid outlet pipe 4461 and is initially set upward. The above valve structure 453 is located in the liquid outlet pipe 4461.

[0049] The liquid dripping prevention structure 447 includes: a gear ring 4471, a rack 4472, and a return spring 4473. Among them, the lower ends of the gear ring 4471 and the rack 4472 are received in the outer end cover 442. In this way, the outer end cover 442 can provide a holding force to the liquid outlet pipe 4461 and the rack 4472, thereby facilitating the maintenance of the stability of the movement of the liquid outlet pipe 4461 and the rack 4472. Specifically, the gear ring 4471 is sleeved on the protruding end of the liquid outlet pipe 4461. The rack 4472 is vertically arranged on one side of the liquid outlet nozzle 446 through a support frame on the liquid storage barrel 41, and the rack 4472 is meshed with the gear ring 4471 through the tooth structure thereon. The return spring 4473 is sleeved on the rack 4472, and one end thereof abuts against the boss at the upper end of the rack 4472, and the lower end abuts against the support frame.

[0050] In this way, when the liquid seasoning discharging unit 44 discharges materials, the rack 4472 moves downward, which can drive the liquid outlet nozzle 446 to pivot, so that its nozzle 4462 faces downward for the liquid seasoning to flow out; when the discharging is finished, the rack 4472 moves upward under the action of the return spring 4473, which can drive the liquid outlet nozzle 446 to pivot, so that its nozzle 4462 faces upward to prevent the liquid outlet nozzle 446 from dripping liquid.

[0051] Furthermore, a liquid storage hopper 4463 is provided on one side of the nozzle 4462 of the liquid outlet nozzle 446. The liquid storage hopper 4463 and the rack 4472 are located on the same side of the liquid outlet nozzle 446, and the opening of the liquid storage hopper 4463 faces upward. In this way, during the process of the liquid outlet nozzle 446 pivoting to the initial position, if liquid seasoning drips, the liquid will drop into the above-mentioned liquid storage hopper 4463, and the stored liquid seasoning can be discharged during the next discharging, thereby avoiding the problem of dripping when the liquid seasoning remains.

[0052] In addition, both sides of the bottom of the barrel body 42 have slots 422, which can cooperate with the limit blocks 181 at the bottom of the corresponding installation positions when the liquid storage barrel 41 is located at the corresponding installation positions to perform circumferential limitation on the liquid storage barrel 41.

[0053] In summary, in the liquid seasoning storage device of the present invention, a filter screen with a closed top and perforated all around is further provided at the discharge port of the liquid storage cavity, and the bottom surface of the liquid storage cavity is inclined towards the discharge port. In this way, it is beneficial for the liquid seasoning to flow towards the discharge port, and when the piston rod is pulled out, the filter screen can suck the liquid seasoning through the perforations around, thereby overcoming the problem that the viscous liquid seasoning accumulates around the discharge port and cannot flow out smoothly.

[0054] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
