Referring to fig. 9 and 10, fig. 9 is an exploded view of an electrolytic oxygen removal device 500 in a refrigerator 1 according to a further embodiment of the present invention, showing the positional relationship of a housing 501, a cap 560 and an exhaust pipe 550, and fig. 10 is an enlarged view at C in fig. 9. In some embodiments, the electrolytic oxygen removal device 500 can also include an exhaust pipe 550.
The top of the shell 501 is provided with an exhaust gas injection port 502, and the exhaust gas injection port 502 not only can be used for discharging oxygen generated on the anode plate 520, but also can be used for a user or a maintenance person to inject electrolyte into the electrolytic cavity, so that the electrolytic oxygen removal device 500 does not need to be integrally disassembled, and is safe and convenient.
One end of the exhaust pipe 550 is communicated with the exhaust gas injection port 502, and the exhaust pipe 550 is bent several times to be bent to delay the flow rate of the electrolyte poured out of the electrolytic chamber. The number of bending times of the exhaust pipe 550 may be two, three or more, and the number of bending times of the exhaust pipe 550 is not particularly limited in this embodiment.
Because the exhaust pipe 550 is disposed at the exhaust gas injection opening 502, and the exhaust pipe 550 is bent and rotated for multiple times to form a bent shape, when the electrolytic oxygen removal device 500 is in an abnormal condition (such as toppling, standing upside down, etc.), the electrolyte in the electrolytic chamber firstly passes through the exhaust pipe 550 when flowing out through the exhaust gas injection opening 502, and the bent exhaust pipe 550 extends and bends the flowing-out path of the electrolyte, thereby delaying the flowing-out time of the electrolyte. And the electrolyte is subjected to the on-way resistance of the inner wall of the exhaust pipe 550 to the electrolyte in the outflow process, so that the flow rate of the electrolyte flowing outwards is reduced, and even the electrolyte can not be discharged from the exhaust pipe 550 under the action of atmospheric pressure, thereby realizing the leakage-proof effect.
As described in the background section, the leakage-proof solution in the prior art is difficult to disassemble for fluid infusion due to the long stroke of the catheter, and is easy to store residual electrolyte, which affects the air permeability. In order to overcome the defects of the prior art, in the electrolytic oxygen removing device 500 of the present embodiment, the exhaust pipe 550 extends and bends the outflow path of the electrolyte in a turning and bending manner, so as to effectively solve the problem of leakage prevention, and the exhaust gas does not protrude on any peripheral wall of the housing 501 in a turning and bending manner, so that the exhaust pipe 550 occupies a small space and is easy to detach, and the maintenance personnel can fill the electrolyte conveniently.
Referring to fig. 10, in some further embodiments, exhaust tube 550 may include a first straight tube section 551, a first curved tube section 552, a second straight tube section 553, a second curved tube section 554, and a third straight tube section 555. The first end of the first straight pipe section 551 communicates with the exhaust gas injection port 502 and extends upward, the first end of the first bent pipe section 552 is formed at the second end of the first straight pipe section 551 and extends while bending downward, the first end of the second straight pipe section 553 is formed at the second end of the first bent pipe section 552 and extends while bending downward, the first end of the second bent pipe section 554 is formed at the second end of the second straight pipe section 553 and extends while bending upward, and the first end of the third straight pipe section 555 is formed at the second end of the second bent pipe section 554 and extends while bending upward.
That is, the exhaust pipe 550 of the present embodiment is bent twice through 180 °, and the first bent pipe section 552 and the second bent pipe section 554 are respectively connected between the first straight pipe section 551 and the second straight pipe section 553, and between the second straight pipe section 553 and the third straight pipe section 555, so as to realize the rotary bending of the exhaust pipe 550.
The utility model discloses the people discovers through a large amount of experiments: the exhaust pipe 550 bent once may still have a liquid leakage phenomenon, and the exhaust pipe 550 bent more than three times may still have liquid accumulation in the pipe after the electrolytic oxygen removal device 500 is tilted and straightened, and the exhaust pipe 550 bent twice can not only prevent leakage, but also is not easy to store residual electrolyte.
In the present embodiment, one end of the exhaust pipe 550 may be directly connected to the exhaust gas filling port 502, or may be indirectly connected to the exhaust gas filling port 502. Specifically, when the exhaust pipe 550 indirectly communicates with the exhaust gas injection port 502, the electrolytic deoxygenator device 500 may further include a cap 560, the cap 560 includes a cap body 561 and a pipe support 562 formed on one side of the cap body 561, the cap body 561 is detachably connected to the exhaust gas injection port 502, and an intake port 563 communicating with the exhaust gas injection port 502 is formed in the cap body 561, and the pipe support 562 has a through hole 564. The first end of the first straight tube segment 551 communicates with the air inlet 563, and the third straight tube segment 555 is inserted through the through hole 564.
The cap body 561 can be detachably mounted on the exhaust gas injection port 502 by means of a snap fit, a threaded connection, or the like, and the air inlet 563 on the cap body 561 can also be hermetically connected to one end of the exhaust pipe 550 by means of a snap fit, an interference fit, a gas path quick connector, or the like.
The pipe bracket 562 is disposed at one side of the cap body 561, and when one end of the exhaust pipe 550 is connected to the air inlet 563, the second straight pipe 553 of the exhaust pipe 550 extends downward first, and then the third straight pipe 555 extends upward and passes through the through hole 564 for limiting and fixing. That is, the cap 560 may fix the exhaust pipe 550 at both ends thereof and can maintain the double-bent state.
After the electrolytic oxygen removal device 500 is used for a period of time, a user or a maintenance person can directly detach the cap 560 to remove the exhaust pipe 550 and expose the exhaust gas injection port 502, so that electrolyte can be conveniently injected, and the cap 560 can be directly added to restore the original position after the injection is completed, so that the operation is simple.
In some embodiments, the pipe diameters of the sections of the exhaust pipe 550 are equal and smaller than the pipe diameter of the intake port 563, so that the exhaust pipe 550 is sleeved on the intake port 563. In addition, because the pipe diameter of the exhaust pipe 550 is smaller than that of the air inlet 563, and because the viscosity of general liquid is larger than that of gas under the same external conditions, the resistance to the liquid is larger and the resistance to the gas is smaller for the exhaust pipe 550 with the smaller pipe diameter, so that the flow speed of the electrolyte in the exhaust pipe 550 when the electrolyte is poured can be effectively delayed, and the influence on the emission of oxygen in a normal use state is smaller.
In some embodiments, a partial section of the exhaust pipe 550 protrudes from at least one side peripheral wall of the housing 501. For example, a partial section of the exhaust tube 550 may protrude from at least one of the side of the housing 501 on which the cathode plate 510 is disposed, the side of the housing 501 facing away from the cathode plate 510, or other sides. Thus, when the electrolytic oxygen removal device 500 is tilted and the exhaust pipe 550 protrudes above the section of the housing 501, the exhaust pipe 550 is ensured to have a section higher than the housing 501, and the electrolyte is prevented from being discharged from the exhaust pipe 550.
In some embodiments, the housing 501 is flat, and the oxygen inlet 512 opens at a wider side of the housing 501. Since the cathode plate 510 covers the oxygen inlet 512, the larger the oxygen inlet 512 is, the larger the area of the cathode plate 510 is, and thus the larger the contact area of the cathode plate 510 and the air is, which improves the electrolysis efficiency of the electrolytic oxygen removing device 500. In addition, the housing 501 is flat, so that the width of the electrolytic oxygen removal device 500 can be shortened, the occupied thickness of the electrolytic oxygen removal device can be reduced, and the space can be saved.
In some embodiments, the exhaust gas injection port 502 may be provided on a side of the case 501 close to the anode plate 520. That is, the exhaust gas injection port 502 is located closer to the anode plate 520 than to the cathode plate 510, and the exhaust gas injection port 502 may be provided on the top rear side of the case 501, which may shorten the discharge path of oxygen gas, facilitating rapid discharge of oxygen gas generated by the anode plate 520.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the utility model may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the utility model.
