Description
Technical Field
The utility model relates to the field of laboratory aseptic operation, in particular to a portable pressure supply device capable of compressing air.
Background
When replenishing the fermenter via a replenishing bottle, it is customary to use peristaltic pumps to supply power or to use a fixed compressed air connection to supply a pressure difference. Under the condition that a compressed air interface is not fixed, only a peristaltic pump power supply mode can be selected, and usually the connecting pipe of the liquid supplementing bottle is very small, and a proper peristaltic pump cannot be found.
Therefore, the technical problems to be solved at present are as follows: the peristaltic pump solves the problem that only the peristaltic pump can provide clean compressed air, and provides other portable and easy-to-carry equipment capable of replacing the peristaltic pump.
Disclosure of Invention

In order to achieve the above purpose, a portable pressure supply device is designed, which comprises a needle cylinder, a first gas one-way valve, a second gas one-way valve and a liquid supplementing bottle, wherein the needle cylinder is connected with one end of a first hose, the other end of the first hose is divided into two paths through a tee joint, one path is connected with the outlet end of the first gas one-way valve through the second hose, and the inlet end of the first gas one-way valve is connected with a first air filter through a fourth hose; the other path of the tee joint is connected with the inlet end of a second gas one-way valve through a third hose, the outlet end of the second gas one-way valve is connected with a liquid supplementing bottle through a fifth hose, and a second air filter is further arranged at the joint of the fifth hose and the liquid supplementing bottle.
Preferably, the first gas check valve directs the gas filtered by the first air filter to the three-way direction.
Preferably, the second gas check valve filters the gas through the second air filter and then sends the filtered gas into the liquid replenishing bottle.
Preferably, the device further comprises a sixth hose, wherein the sixth hose is connected with the liquid supplementing bottle and the external atmosphere.
Compared with the prior art, the utility model has the advantages that:
1. providing a simple and convenient source of clean compressed air;
2. the situation that compressed air is not available and a proper peristaltic pump cannot be found in the liquid replenishing process of the liquid replenishing bottle is avoided;
3. the whole device is light, easy to carry and convenient to assemble;
4. can ensure the sterility of the air entering the fluid infusion bottle.
Drawings
Fig. 1 is a schematic structural view of a pressure supply device provided by the utility model.
In the figure: 1. a first hose; 2. a second hose; 3. a third hose; 4. a fourth hose; 5. a fifth hose; 6. a sixth hose; 7. a first gas check valve; 8. a second gas check valve; 9. a first air filter; 10. a second air filter; 11. a needle cylinder; 12. and (5) a tee joint.
Detailed Description
The construction and principles of the present utility model will be readily apparent to those skilled in the art from the following description taken in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
As shown in FIG. 1, the portable pressure supply device of the utility model comprises a needle cylinder 11, a first gas one-way valve 7, a second gas one-way valve 8, a first air filter 9, a second air filter 10 and a fluid infusion bottle.
The needle cylinder 11 is connected with one end of the first hose 1, the other end of the first hose 1 is divided into two paths through a tee joint 12, one path is connected with the outlet end of a first gas one-way valve 7 with 0.2um through a second hose 2, the inlet end of the first gas one-way valve 7 is connected with a first air filter through a fourth hose 4, and the first gas one-way valve 7 sends the gas filtered by the first air filter to the direction of the tee joint 12;
the other path of the tee joint 12 is connected with the inlet end of a second gas one-way valve 8 through a third hose 3, the outlet end of the second gas one-way valve 8 is connected with a liquid supplementing bottle through a fifth hose 5, a second air filter of 0.2um is further arranged at the joint of the fifth hose 5 and the liquid supplementing bottle, the liquid supplementing bottle is connected with the outside atmosphere through a sixth hose 6, and the second gas one-way valve 8 filters gas through the second air filter and then sends the filtered gas into the liquid supplementing bottle.
The tee joint 12 pipeline can ensure that the air source and the air supply passage are independent.
The air filtered by the air filter is continuously pumped by the needle cylinder 11 to enter the fluid infusion bottle, so that the pressure in the fluid infusion bottle is higher than the pressure of the external air, and the pressure difference is utilized to promote the fluid to flow along the pipeline from the fluid infusion bottle, thereby avoiding the condition that the peristaltic pump cannot be found and power cannot be provided.
The pressure supply device comprises the following steps:
when the piston of the needle cylinder 11 is pushed, the air in the needle cylinder 11 sequentially passes through the first hose 1, the tee joint 12, the first hose 1, the tee joint 12, the third hose 3, the second air check valve 8, the fifth hose 5 and the second air filter 10, the air is changed into clean air through 2 times of filtration and enters the liquid replenishing bottle, when the air passes through the tee joint 12, a part of air passes through the second hose 2 and enters the first air check valve 7, but the first air check valve 7 is an inward check valve, when the piston is pushed, the first air check valve 7 is in a closed state and can not pass through, so that all air can continuously enter the liquid replenishing bottle, the second air check valve 8 is an outward check valve, the air entering the liquid replenishing bottle can not flow back into the needle cylinder 11 and only can be converged in the liquid replenishing bottle, the pressure difference in the liquid replenishing bottle is enabled to be larger than the external air pressure, and the liquid in the sixth hose 6 flows out of the liquid bottle.
The above description is only specific to the embodiments of the utility model, but the scope of the utility model is not limited thereto, and any person skilled in the art who is skilled in the art to which the utility model pertains shall apply to the technical solution and the novel concept according to the utility model, and shall all be covered by the scope of the utility model.
