Description

Technical Field

[0001] This utility model relates to the field of sterile bottles, and in particular to a manual sampler for sterile bottles. Background Technology

[0002] Aseptic bottles are packaging containers that kill all microorganisms in the bottle body and inside through physical or chemical means and maintain a sterile state during subsequent storage and use. The bottle body is generally made of glass and is widely used in fields with zero tolerance for microbial contamination, such as medicine, biological experiments, and food and beverage. Conventional sterile bottle samplers use valves and other well-sealed components to sample the liquid inside the bottle. While valves are suitable for use in larger sterile containers, they are not ideal for sampling smaller sterile bottles. Therefore, we propose a manual sterile bottle sampler. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a manual sampler for sterile bottles. By setting a sterile air bladder, sterile gas is filled into it and then squeezed into the interior of the sterile bottle. After the sterile air bladder has squeezed out all the gas, the block inside it blocks the lower end of the soft pad, preventing the gas from flowing back. At this time, the gas pressure forces the liquid inside the sterile bottle to be sprayed out from the sampling nozzle through the sampling tube, thus completing the sampling of the sterile bottle.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A manual sampler for sterile bottles includes a bottle body mechanism, a liquid dispensing mechanism installed in the middle of the bottle body mechanism, and a sampling mechanism installed on the left side of the liquid dispensing mechanism. The sampling mechanism includes a sterile airbag. An air inlet valve is fixedly installed on the upper side of the sterile airbag. A top block is fixedly installed on the top of the inner end of the sterile airbag. A top rod is fixedly installed on the lower end of the top block. A blocking block is fixedly installed on the lower end of the top rod. A soft pad is fixedly installed below the inner end of the sterile airbag. A groove is formed in the middle of the soft pad. The top block facilitates the application of force to the top rod. The groove creates a gap in the middle of the soft pad, which facilitates the downward movement and penetration of the blocking block. In this structure, the lower end of the blocking block has an arc shape, so the resistance is small when it contacts the groove, making it easy to penetrate the soft pad.

[0005] Furthermore, the bottle body mechanism includes a sterile bottle body, a scale is fixedly provided at the outer end of the sterile bottle body, a bottle cap is fixedly installed at the upper end of the sterile bottle body, and a through hole is opened in the middle of the bottle cap. The scale allows the amount of sample taken from the sterile bottle body to be observed at any time and controlled according to the specific volume.

[0006] Furthermore, the liquid dispensing mechanism includes a sampling tube with sampling nozzles on the left and right sides of the upper end of the sampling tube. A control valve is fixedly installed in the middle of the sampling nozzle. An air inlet pipe is fixedly connected to the left side of the upper end of the sampling tube. The control valve controls the flow rate of liquid drawn by the sampling nozzle, so that the device can control the liquid after it draws it.

[0007] Furthermore, the sterile airbag is fixedly installed at the upper end of the air inlet pipe, and the push rod passes through the middle of the soft pad through the groove. During operation, the sterile airbag is filled with sterile gas. By squeezing the sterile airbag, the sterile gas inside is squeezed into the interior of the sterile bottle. During squeezing, the push rod passes down through the soft pad. When the gas is squeezed out, the plug is just stuck at the lower end of the soft pad, keeping the soft pad airtight and preventing gas backflow.

[0008] Furthermore, the diameter of the plug is larger than the diameter of the groove. This ensures that the groove in the pad remains sealed. The pad is made of latex material, which has high toughness and is not prone to aging or damage. This reduces the replacement cost of the structure and extends the service life of the device.

[0009] Furthermore, the sampling tube is fixedly installed in the middle of the bottle cap through a through hole, and the lower end of the sampling tube extends into the interior of the sterile bottle.

[0010] Furthermore, the air intake pipe and the interior of the sterile air bag are connected.

[0011] In summary, this utility model has the following beneficial effects: 1. By setting a sterile airbag, sterile gas is filled into it and then squeezed into the inside of the sterile bottle. After the sterile airbag has squeezed out all the gas, the block inside it blocks the lower end of the soft pad, preventing the gas from flowing back. At this time, the gas pressure will spray the liquid inside the sterile bottle through the sampling tube from the sampling nozzle, thus completing the sampling of the sterile bottle. 2. During operation, the sterile airbag is filled with sterile gas. Squeeze the sterile airbag to force the sterile gas inside into the sterile bottle. During squeezing, the push rod goes down through the soft pad. When the gas is squeezed out, the plug is just stuck at the lower end of the soft pad, keeping the soft pad airtight.

A through hole 104 is opened in the middle of the bottle cap 103. The scale 102 allows the amount of sample taken from the sterile bottle body 101 to be observed at any time and controlled according to the specific volume.

[0018] The liquid dispensing mechanism 2 includes a sampling tube 201, with sampling nozzles 202 on the left and right sides of the upper end of the sampling tube 201. A control valve 203 is fixedly installed in the middle of the sampling nozzles 202. An air inlet pipe 204 is fixedly connected to the left side of the upper end of the sampling tube 201. The control valve 203 controls the flow rate of liquid drawn by the sampling nozzles 202, so that the device can control the flow rate after drawing liquid.

[0019] The sterile airbag 301 is fixedly installed at the upper end of the air inlet pipe 204. The push rod 304 passes through the middle of the soft pad 306 through the groove 307. During operation, the sterile airbag 301 is filled with sterile gas. By squeezing the sterile airbag 301, the sterile gas inside is squeezed into the sterile bottle body 101. During the squeezing, the push rod 304 goes down through the soft pad 306. When the gas is squeezed out, the plug 305 is just stuck at the lower end of the soft pad 306, keeping the soft pad 306 airtight and preventing gas backflow.

[0020] The diameter of the plug 305 is larger than the diameter of the groove 307. This ensures that the groove 307 in the pad 306 remains sealed. The pad 306 is made of latex material, which is tough and not easily aged or damaged.

[0021] The sampling tube 201 is fixedly installed in the middle of the bottle cap 103 through the through hole 104. The lower end of the sampling tube 201 extends into the interior of the sterile bottle body 101. Sterile gas enters the interior of the sterile bottle body 101 through the sampling tube 201. After the air enters the interior of the sterile bottle body 101, the soft pad 306 inside the sterile air bladder 301 closes, and the gas inside the sterile bottle body 101 is ejected from the sampling nozzle 202 connected to the upper end of the sampling tube 201. This completes the manual sampling of the sterile bottle body 101.

[0022] The air inlet pipe 204 is internally connected to the sterile air bag 301, and the air inlet pipe 204 is used to connect the sterile air bag 301 and the sampling tube 201.

[0023] Specific implementation process: The technical content of this utility model is a manual sampler for sterile bottles. First, the sampling tube 201 is fixed to the middle of the bottle cap 103 through the through hole 104, and its lower end extends into the interior of the sterile bottle body 101. A sampling nozzle 202 and a control valve 203 are installed at the top of the sampling tube 201. The middle of the sampling tube 201 is connected to a sterile air bag 301 through an air inlet pipe 204. During operation, the sterile air bag 301 is filled with sterile gas. At this time, squeezing the sterile air bag 301 forces the sterile gas inside into the interior of the sterile bottle body 101. During squeezing, the push rod 304 penetrates the soft pad 306 downwards. When the gas is squeezed out, the plug 305 is just stuck in the soft pad. The lower end of 306 keeps the soft pad 306 airtight, preventing gas backflow. Since the lower end of the sampling tube 201 extends into the sterile bottle body 101, sterile gas enters the sterile bottle body 101 through the sampling tube 201. After air enters the sterile bottle body 101, the soft pad 306 inside the sterile airbag 301 closes, and the gas inside the sterile bottle body 101 is ejected from the sampling nozzle 202 connected to the upper end of the sampling tube 201. This completes the manual sampling of the sterile bottle body 101. The various components of this device complement each other, making sterile bottle sampling fast and convenient. At the same time, it is simple to operate and has a simple structure, making it suitable for widespread use in many industries.
