As shown in fig. 1 and 3, the present invention provides an air pumping and charging switching device, which includes an air inlet passage 100, an air outlet passage 200, and an air pump 300 disposed between the air inlet passage 100 and the air outlet passage 200, wherein the air pump 300 is capable of driving air to move from the air inlet passage 100 toward the air outlet passage 200.
The intake passage 100 has two inlets, an intake port 111 communicating with the outside, and an extraction port 121 for extracting air. The air outlet passage 200 has two outlets, an air outlet 211 communicating with the outside and an air charging port 221 for charging air.

When inflation is required, the switching mechanism 400 is switched to the second state, the air suction opening 121 and the air outlet 211 are closed, air enters through the air inlet 111, and flows out from the inflation opening 221 after being pressurized by the air pump 300, and at this time, the inflation opening 221 is in a positive pressure state, so that inflation operation can be performed on the equipment.
From the above, the air inlet end and the air outlet end of the air pump 300 can respectively bear the functions of air suction and air inflation by the switching mechanism 400, so that the air suction and air inflation switching can be realized by only one air pump 300.
In this embodiment, the air intake passage 100 is formed by an air intake branch pipe 110 and an air exhaust branch pipe 120, one end of the air intake branch pipe 110 is connected to the air intake port 111, the other end is connected to the air intake end of the air pump 300, one end of the air exhaust branch pipe 120 is adjacent to the air exhaust port 121, and the other end is also connected to the air intake end of the air pump 300. The air outlet passage 200 is composed of an air outlet branch pipe 210 and an air charging branch pipe 220, one end of the air outlet branch pipe 210 is connected with the air outlet 211, the other end is connected with the air outlet end of the air pump 300, one end of the air charging branch pipe 220 is connected with the air charging port 221, and the other end is connected with the air outlet end of the air pump 300. The air inlet branch pipe 110, the air outlet branch pipe 120, the air outlet branch pipe 210 and the air inlet branch pipe 110 are all flexible pipes, can deform under the action of external force and can recover after the external force disappears. The hose is adopted to be respectively communicated with the air inlet 111, the air outlet 211, the air charging port 221 and the air extracting port 121, so that the positions of the hose can be conveniently adjusted, the structural layout is convenient to carry out, the layout is favorable to be optimized, and the design difficulty is reduced.
As shown in fig. 2, in the present embodiment, the switching mechanism 400 includes a rotary table 410 capable of being driven to rotate by a motor 411 and a placement surface 420 with a gap left between the rotary table 410, the inlet manifold 110, the outlet manifold 210, the exhaust manifold 120 and the air manifold 220 pass through the gap between the rotary table 410 and the placement surface 420, the outer peripheral wall of the rotary table 410 is composed of two parts, a body part 412 for allowing the inlet manifold 110, the outlet manifold 210, the exhaust manifold 120 and the air manifold 220 to pass through the gap and a protrusion part 413 capable of filling the gap are left between the placement surface 420, respectively, and when the rotary table 410 is in a first state, the protrusion part 413 presses and closes the inlet manifold 110 and the air manifold 220, and the body part 412 is arranged corresponding to the exhaust manifold 120 and the outlet manifold 210 for conduction. When the rotary table 410 is in the second state, the protruding portion 413 presses and closes the suction manifold 120 and the discharge manifold 210, and the body portion 412 is disposed corresponding to the suction manifold 110 and the gas-filled manifold 220 for communication.
Through the switching structure, the switching between the pumping state and the inflating device of the pumping and inflating device is realized. The switching mechanism 400 only comprises one action mechanism of the rotary table 410, and has the advantages of simple structure, convenient arrangement and contribution to reducing the volume of equipment.
In this embodiment, the inlet manifold 110 and the outlet manifold 220 are disposed adjacent to each other at the placement surface 420 to form a stack of gas tubes, and the outlet manifold 210 and the outlet manifold 120 are disposed adjacent to each other at the placement surface 420 to form a stack of gas tubes. With such a structure, since the protruding portion 413 of the turntable 410 necessarily sequentially extrudes and seals the pipelines during rotation, sealing of two pipelines in the air exhaust pipe group and the air inflation pipeline necessarily has a certain time interval, and the adjacent arrangement of two pipelines in the air exhaust pipe group and the air inflation pipe group can reduce the sealing time interval of the two pipelines to the minimum, so that the switching efficiency of the air exhaust state is improved. And meanwhile, the accuracy of controlling the pumping and inflating time is improved.
Specifically, in this embodiment, the placement surface 420 is two oppositely disposed arc surfaces, the air suction tube set is disposed on one of the arc surfaces, the air inflation tube set is disposed on the other arc surface, and the included angle between the air suction tube set and the air inflation tube set is 180 ° with respect to the rotation axis of the turntable 410. The layout is more reasonable, and under the cooperation of the pumping and inflating switching device and the identification mark, an assembler can assemble the pumping and inflating switching device with difficulty in error. Nor is the inflation inlet 221 easily confused by the user.
In this embodiment, the protruding portion 413 is disposed in a fan shape, and an included angle between two ends of the protruding portion 413 and the rotating shaft of the turntable 410 is equal to or slightly smaller than an included angle between the air pumping tube set and the air charging tube set and the rotating shaft of the turntable 410. With such a structure, when one end of the protruding portion 413 presses and closes one of the suction tube group and the inflation tube group, the other end of the protruding portion 413 can be brought close to the unsealed suction tube group or inflation tube group. When the pumping and inflating switch is needed, the protruding part 413 only needs to rotate a small angle to realize the switch from the first state to the second state. So can increase substantially the speed of pumping and inflating switching, improve the performance of the product.
To prevent displacement of the protrusions 413 when they press the inlet manifold 110, the outlet manifold 120, the outlet manifold 210, and the air charge manifold 220 from causing the inlet manifold 110, the outlet manifold 120, the outlet manifold 210, and the air charge manifold 220 to leave predetermined positions on the placement surface 420, the protrusions 413 cannot completely close them, and air leakage occurs. The placement surface 420 is further provided with a plurality of positioning grooves (not shown) arranged along the vertical direction, and the air inlet branch pipe 110, the air outlet branch pipe 120, the air outlet branch pipe 210 and the air charging branch pipe 220 are correspondingly arranged in the positioning grooves. Thereby achieving a positioning effect.
In the present embodiment, the air inlet branch pipe 110 and the air outlet branch pipe 120 are connected to the air pump 300 through the first multi-way valve 130, and the air inlet branch pipe 220 and the air outlet branch pipe 210 are connected to the air pump 300 through the second multi-way valve 230. The first multi-way valve 130 and the second multi-way valve 230 are three-way valves. Thus, the straight intake pipe and the branch exhaust pipe 120 are connected to the air pump 300 through a general intake pipe after passing through the first multi-way valve 130. The air-filling branch pipe 220 and the air-discharging branch pipe 210 are communicated with an air pump 300 through a second multi-way valve 230 and a general air outlet pipe. By adopting the structure, the length of each branch pipe can be reduced, the cost is reduced, meanwhile, the pipeline arrangement is simpler and convenient to arrange, and in addition, the possibility of faults caused by entanglement of the pipeline can be reduced by the simpler pipeline.
It should be noted that the above is only a preferred embodiment of the switching mechanism 400, and alternatively, the switching mechanism 400 may be four push blocks respectively driven and controlled, and the air inlet branch pipe 110, the air outlet branch pipe 120, the air charging branch pipe 220 and the air outlet branch pipe 210 pass through the gaps between the push blocks and the placing surface 420, and the air charging and discharging switching is implemented by driving the push blocks to squeeze and close the air inlet branch pipe 110, the air outlet branch pipe 120, the air charging branch pipe 220 and the air outlet branch pipe 210. As another alternative, the switching mechanism 400 can also be valves provided in the suction manifold 120, the intake manifold 110, the suction manifold 120, and the inflation manifold 220, and the switching mechanism can be turned on and off by switching the valves. Thereby realizing pumping and inflating switching. However, the above schemes all need to control four units separately to realize the pumping and inflating switching, and the design and manufacturing are more complicated than the scheme that only one unit of the turntable 410 is controlled to realize the pumping and inflating switching, so that the above switching mechanism 400 is still preferably adopted.
The invention also provides a quantitative discharging mechanism for the liquid seasonings, which comprises a containing cavity for containing the seasonings and the pumping and inflating switching device, wherein the pumping and inflating switching device is communicated with a gas containing area in the containing cavity. The accommodating cavity is in a closed state, when gas is filled into the accommodating cavity, the air cavity in the accommodating cavity is increased, liquid is extruded out of the accommodating cavity, and quantitative control on discharging can be realized by controlling the charging time. When the accommodating cavity is pumped, the air cavity in the accommodating cavity is reduced, and external air enters the accommodating cavity from the outlet of the accommodating cavity under the action of air pressure, so that liquid does not flow out any more, and blanking is stopped. Realizes the quantitative discharging of the liquid seasoning.
The invention also provides a cooking machine comprising the liquid seasoning quantitative discharging mechanism. The cooking machine can realize high-precision liquid blanking and has good cooking efficiency and effect.
