The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See also Figures 1 to 6 The utility model discloses a flavor infusion device, which is mainly used for the flavor infusion process, and of course can also be extended to the infusion of other liquids.

[0030] The essence infusion equipment of the utility model comprises a frame 1, a conveying device 2, an infusion assembly 3, a liquid extraction assembly 4, a storage tank 5 and a lifting drive mechanism 6, wherein:

[0031] The conveying device 2 is arranged on the frame 1, and is used for continuously or intermittently conveying the perfusion bottles 7 stacked in rows in a direction from back to front.

[0032] The conveying device 2 includes a conveying platform 21 and at least two rows of conveying channels 22 arranged on the conveying platform 21. The width of each row of conveying channels 22 is consistent with the width of a single perfusion bottle 7, so that multiple perfusion bottles 7 are arranged in sequence and conveyed from the rear end to the front end of the frame 1. The rear end of the frame 1 corresponds to the feeding end of the conveying platform 21, and the front end of the frame 1 corresponds to the discharging end of the conveying platform 21.

[0033] This embodiment mainly takes the arrangement of two rows of delivery channels 22 as an example. It can be imagined that the number of delivery channels 22 is arranged corresponding to the number of filling components 31 and liquid pumping components 41 in the filling assembly 3.

[0034] At least one filling assembly 3 is provided, and each filling assembly 3 includes two groups of filling components 31 . Each group of filling components 31 includes a filling head 311 and a material delivery pipe 312 . The material delivery pipe 312 is connected to the filling head 311 .

[0035] At least one set of the liquid pumping assembly 4 is provided, and each set of the liquid pumping assembly 4 includes two groups of liquid pumping components 41 , and each group of liquid pumping components 41 is provided in a one-to-one correspondence with the filling components 31 .

[0036] Each group of liquid pumping components 41 includes a liquid pumping piston cylinder 411, a liquid inlet pipe 412, a liquid outlet pipe 413, a liquid inlet check valve 414 and a liquid outlet check valve 415. The liquid pumping piston cylinder 411 is provided with a liquid pumping chamber 4111 and a movable piston 4112. The movable piston 4112 moves in the liquid pumping chamber to pump / discharge the liquid. The movable piston 4112 includes a piston rod 41121, which is connected to the lifting drive mechanism 6 described below via the piston rod 41121.

[0037] The liquid inlet pipe 412 and the liquid outlet pipe 413 are both connected to the liquid pumping piston cylinder 411 and communicate with the liquid pumping chamber 4111. The liquid outlet pipe 413 is connected to the feed pipe 312 in the corresponding filling component 31 via a liquid outlet one-way valve 415. The liquid outlet one-way valve 415 only allows liquid to be discharged from the liquid pumping piston cylinder 411 through the liquid outlet pipe 413, and does not allow the liquid to flow back through the liquid outlet pipe 413.

[0038] The storage tank 5 is arranged on the frame 1 and has a discharge port (not marked in the figure). The discharge port is connected to the corresponding liquid inlet pipe 412 through the liquid inlet one-way valve 414 in each group of liquid pumping components 41. The liquid inlet one-way valve 414 only allows liquid to flow from the liquid storage tank through the liquid inlet pipe 412 to the liquid pumping piston cylinder 411, and does not allow the liquid to flow back from the liquid pumping piston cylinder 411 to the liquid storage tank through the liquid inlet pipe 412.

[0039] The lifting drive mechanism 6 is arranged on the frame 1, and the lifting drive mechanism 6 is connected to the filling head 311 and the movable piston 4112 of the liquid extraction piston cylinder 411. The lifting drive mechanism 6 drives the filling head 311 to rise and fall to move away from or close to the platform of the conveying device 2, and can drive the movable piston 4112 to move up and down to expand or shrink the liquid extraction chamber 4111.

[0040] Through the above arrangement, a set of filling assembly 3 corresponds to a set of pumping assembly 4 and a lifting drive mechanism 6, wherein each set of filling assembly 3 includes two sets of filling components 31, and each set of pumping assembly 4 includes two sets of pumping components 41, by arranging a liquid inlet check valve 414 on the liquid inlet pipe 412 connecting the pumping piston cylinder 411 and the material storage tank 5, and arranging a liquid outlet check valve 415 on the liquid outlet pipe 413 between the pumping piston cylinder 411 and the filling head 311, the opening and closing states of the liquid inlet check valve 414 are opposite, so that when the lifting drive mechanism 6 is actuated once, only liquid is introduced or discharged from the pumping piston cylinder 411, and since a set of filling assembly 3 has two sets of filling components 31 and pumping components 41, two filling bottles 7 can be filled with liquid at the same time, and the filling efficiency is high, and the lifting drive mechanism 6 connects the filling head 311 and the corresponding movable piston 4112, so that:

[0041] See also Figure 4 When the lifting drive mechanism 6 lifts the perfusion head 311 away from the perfusion bottle 7, the liquid inlet check valve 414 (I1, I2) opens, and the liquid outlet check valve 415 (O1, O2) closes, and the movable piston 4112 can be synchronously driven to move and pump liquid;

[0042] See also Figure 5 When the lifting drive mechanism 6 drives the perfusion head 311 to descend close to the perfusion bottle 7, the liquid inlet one-way valve 414 (I1, I2) is closed, and the liquid outlet one-way valve 415 (O1, O2) is opened, which can synchronously drive the movable piston 4112 to move and discharge liquid, and the perfusion head 311 injects liquid into the corresponding perfusion bottle 7, simplifying the structure of the perfusion equipment.

[0043] This achieves the purpose of simplifying the structure and improving the perfusion efficiency.

[0044] See also Figures 1 to 6In an optional embodiment, the lifting drive mechanism 6 includes a column 61 and a first connecting arm 62 and a second connecting arm 63 connected to the column 61. The column 61 is connected to the injection head 311 and the movable piston 4112. The first connecting arm 62 is used to connect the two movable pistons 4112 of each set of liquid extraction assembly 4, and the second connecting arm 63 is used for the two injection heads 311 in each set of injection assembly 3.

[0045] Through such an arrangement, in a set of lifting drive mechanism 6, the first connecting arm 62 is connected to the second connecting arm 63 through a column 61, and the first connecting arm 62 is connected to the two movable pistons 4112 of each set of pumping assembly 4, and the second connecting arm 63 is connected to the two filling heads 311 in each set of filling assembly 3, so that the lifting drive mechanism 6 can synchronously drive the two groups of filling components 31 in each set of filling assembly 3 and the pumping components 41 in each set of pumping assembly 4, so as to realize the synchronization of the movement of the filling head 311 and the pumping / discharging action of the pumping piston cylinder 411, so as to simplify the structure and improve the perfusion efficiency.

[0046] See also Figure 4 as well as Figure 5 In an optional embodiment, the lifting drive mechanism 6 includes an electric push rod 64, which has a fixed end (not marked in the figure) and a movable end (not marked in the figure), wherein the fixed end is fixed to the frame 1 in the vertical direction, and the movable end is connected to the column 61.

[0047] Through such an arrangement, one implementation method is to drive the column 61 to move up and down in the vertical direction through the electric push rod 64 to achieve the purpose of driving the perfusion assembly 3 and the pumping assembly 4 to move.

[0048] See also Figure 6 In an optional embodiment, the lifting drive mechanism 6 includes a lifting drive motor 65 and a transmission member 66. The column 61 is provided with a receiving member 611. The transmission member 66 is connected to the lifting drive motor 65 and rotates under the drive of the lifting drive motor 65. The transmission member 66 can abut against the receiving member 611 to drive the column 61 to move in the vertical direction.

[0049] By such arrangement, as another embodiment, the lifting drive motor 65 drives the transmission member 66 to move, and the transmission member 66 can abut against the receiving member 611 provided on the column 61, so that the column 61 is driven to move in the vertical direction as the transmission member 66 moves.

[0050] See also Figure 6 In an optional embodiment, the lifting drive mechanism 6 also includes a reset elastic member 67, one end of the reset elastic member 67 is connected to the frame 1, and the other end is connected to the column 61, and the reset elastic force Fx applied by the reset elastic member 67 to the column 61 is opposite to the direction in which the lifting drive mechanism 6 drives the column 61 to move.

[0051] In order to simplify the structure of the lifting drive mechanism 6 and facilitate the resetting of the column 61, a resetting elastic force is applied to the column 61 through the resetting elastic member 67, and the direction of the resetting elastic force is opposite to the direction in which the lifting drive mechanism 6 drives the column 61 to move. The lifting drive mechanism 6 needs to overcome the resetting elastic force of the resetting elastic member 67 to drive the column 61 to move; and during the return journey, the resetting elastic member 67 can drive the column 61 to move for resetting.

[0052] See also Figure 6 As a possible implementation, the lifting drive mechanism 6 drives the column 61 to move upward to pump liquid, and the reset elastic member 67 can be configured to apply a vertical downward reset elastic force to the column 61, that is, the reset elastic member 67 can drive the column 61 to move downward to reset in the normal state (when the lifting drive mechanism 6 does not apply a driving force to the column 61);

[0053] Similarly, as another possible implementation, if the lifting drive mechanism 6 is set to drive the column 61 to move downward to perform drainage and infusion, the reset elastic member 67 can be set to apply a vertical upward reset elastic force to the column 61, that is, under normal conditions (when the lifting drive mechanism 6 does not apply a driving force to the column 61), the reset elastic member 67 can drive the column 61 to move upward for reset.

[0054] Furthermore, the reset elastic member 67 may be a compression spring or a tension spring, and the selection thereof is determined according to the arrangement position of the reset elastic member 67 and the direction of the reset elastic force required to be applied to the column 61 .

[0055] In an optional embodiment, the transmission member 66 includes a cam, which is driven by the lifting drive motor 65, and the connecting member 611 is in contact with the outer surface of the cam. The cam is arranged on the upper side of the connecting member 611. The cam rotates and abuts against the connecting member 611 under the drive of the lifting drive motor 65 to drive the connecting member 611 to move downward, thereby driving the injection head 311 and the movable piston 4112 to descend.

[0056] Alternatively, see Figure 6 The cam is arranged at the lower side of the receiving member 611 , and the cam is driven by the lifting drive motor 65 to rotate and abut against the receiving member 611 to drive the receiving member 611 to move upward, thereby driving the injection head 311 to rise and the movable piston 4112 .

[0057] By configuring in this way, the lifting drive motor 65 is combined with the cam, which has a simple structure and is easy to manufacture.

[0058] See also Figure 1 -to Figure 3In an optional embodiment, it also includes a detection element 8, which is connected to a controller (not shown in the figure). A delivery power device 9 is provided below the delivery channel 22, and the delivery power device 9 is electrically connected to the controller. The detection element 8 is arranged on the side of the delivery channel 22 to detect whether there is a perfusion bottle 7 at the perfusion position below the perfusion head 311.

[0059] Among them, the conveying device 2 includes a conveyor belt, and the conveying power device 9 is a prior art, mainly including a motor and a transmission device, and the power is transmitted to the conveyor belt through the transmission device to drive the perfusion bottle 7 located on the conveyor belt to move linearly.

[0060] The controller is a prior art, and may be a single chip microcomputer, a PLC controller, etc.

[0061] Through such an arrangement, the detection element 8 can detect whether there is a perfusion bottle 7 to be perfused at the perfusion station located below the perfusion head 311 in the conveying power device 9. Based on the detection signal, the controller can control the movement of the conveying power device 9. That is, if no perfusion bottle 7 is detected, the controller can control the conveying power device 9 to move the conveying perfusion bottle 7 forward based on the detection signal, thereby improving the automation level of the perfusion process.

[0062] In an optional embodiment, the detection element 8 is a photoelectric sensor or an ultrasonic sensor.

[0063] By configuring in this way, different types of detection elements 8 can be selected according to actual on-site needs. For example, ultrasonic sensors may be preferred in situations where the light is strong and there is much light interference.

[0064] See also Figure 1-Figure 3 In an optional embodiment, two sets of liquid extraction assemblies 4 and perfusion assemblies 3 are sequentially arranged along the conveying direction of the conveying channel 22.

[0065] By setting up two sets of liquid extraction assemblies 4 and infusion assemblies 3, when one set of liquid extraction assemblies 4 and infusion assemblies 3 is in the process of extracting liquid, the other set of liquid extraction assemblies 4 and infusion assemblies 3 can discharge liquid for infusion. The two sets of liquid extraction assemblies 4 and infusion assemblies 3 can make full use of the time difference of extracting or discharging liquid to perform alternating operations, so as to maximize the efficiency of infusion and maintain the continuity of the forward movement of the infusion bottle 7.

[0066] See also Figure 4-Figure 6 In an optional embodiment, the diameter of the liquid inlet pipe 412 is larger than the diameter of the liquid outlet pipe 413 .

[0067] With such an arrangement, the large-diameter liquid inlet pipe 412 enables a large flow rate of liquid to be pumped during the pumping process, while the small-diameter liquid outlet pipe 413 is conducive to pressurizing the discharged liquid to quickly discharge the liquid in the pumping piston cylinder 411 for infusion.

[0068] In summary, the essence infusion device of the present invention can simplify the structure of the infusion device and improve the liquid injection efficiency.

[0069] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
