Description

Technical Field

[0001] The invention relates to a bubble counter. Background Art

[0002] The bubble counter is used to measure the flow rate, size, etc. of the gas passing through the pipeline. Most existing bubble counters are vertical, with the air inlet located at the bottom of the bubble counter and the air outlet located at the top of the bubble counter. Then, by placing liquid in the bubble counter, the effect of gas bubbling in the liquid is achieved. The operator observes the size and speed of the bubbles to know the total gas content.

[0003] Existing bubble counters are used in aquarium equipment. They are connected to carbon dioxide cylinders to supply carbon dioxide in the fish tank, providing nutrients for photosynthesis for the green plants in the fish tank. However, during the use of the existing bubble counter, the carbon dioxide gas will take away the water in the bubble counter during the flow. Over time, the amount of water in the bubble counter gradually decreases, seriously affecting the actual metering effect. Therefore, the operator needs to add water to the bubble counter. The existing operation method is to stop all equipment and then disassemble the bubble counter to add water. This operation method requires stopping the equipment, which seriously affects the actual normal use effect. Summary of the invention

[0004] The main technical problem solved by the invention is to provide a bubble counter.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a bubble counter, which includes a main body, the main body is provided with an air inlet, an air outlet, a cavity, a water injection port, a water injection channel, a first one-way valve assembly and a second one-way valve assembly, one end of the water injection channel is connected to the water injection port, and the other end of the water injection channel is connected to the cavity, the first one-way valve assembly is located between the air inlet and the cavity, the second one-way valve assembly is located at the connection between the water injection channel and the cavity, and the water injection channel has no intersection with the air outlet.

[0006] With this structural setting, due to the setting of the first one-way valve assembly, the water in the cavity will not flow back into the carbon dioxide cylinder through the air inlet, and the normal carbon dioxide gas can be discharged into the water cylinder through the air outlet. When water needs to be injected into the cavity, it can be injected through the water injection port, but due to the setting of the second one-way valve assembly, only external water can enter the cavity, and the gas in the cavity cannot be discharged through the water injection channel. This structural setting makes it possible to achieve the effect of adding water by simply adding water to the water injection port during normal use without stopping the operation of related equipment or performing disassembly operations, thereby satisfying the normal operation of the bubble counter.

[0007] The main body further comprises an air outlet channel, one end of which is connected to the cavity and the other end of which is connected to the air outlet. The air outlet channel has no intersection with the second one-way valve assembly.

[0008] The air outlet channel is arranged in this structure mainly taking into account the space utilization rate, while at the same time ensuring normal air outlet, preventing the air outlet channel from crossing with the water injection channel, and preventing the bubble counter from being discharged from the air outlet along with the carbon dioxide gas during normal use, thereby failing to achieve the water injection effect. At this time, the injected water will not flow into the cavity.

[0009] The second one-way valve assembly and the cavity are not coaxially arranged.

[0010] Since the second one-way valve assembly is relatively large in size, a different axis setting is adopted to reduce the impact of the second one-way valve assembly on the overall space. At the same time, the second one-way valve assembly is easier to install and fix by adopting a different axis setting. Moreover, during the water injection process, the state of the water flow can be observed more intuitively, thereby improving the convenience of water injection.

[0011] Wherein, a protrusion is arranged in the main body, and the second one-way valve component abuts against the protrusion.

[0012] The setting of the protrusion makes it easier for water to flow in the water injection channel after water injection, and better communicates with the inside of the cavity.

[0013] It also includes a first joint and a shell, the air outlet, the water injection port, and the second one-way valve assembly are all located in the first joint, and the shell is threadedly connected to the first joint.

[0014] The first joint is adopted to facilitate the overall processing, and the shell is threadedly connected to the first joint, so the overall assembly efficiency is greatly improved.

[0015] The invention also includes a first sealing member, which is located between the shell and the first joint.

[0016] The first sealing member is provided to provide a better sealing effect between the housing and the first joint.

[0017] The utility model further comprises a second joint, the first one-way valve assembly is located in the second joint, and the second joint is threadedly connected to the shell.

[0018] The provision of the second joint also makes it easier to fix the first one-way valve assembly, and then the second joint is connected and matched with the housing, so that the overall assembly efficiency is increased.

[0019] The invention also includes a second sealing member, which is located between the shell and the second joint.

[0020] The second sealing member is provided to provide a better sealing effect between the housing and the second joint.

[0021] The invention also includes a third sealing component, which is located at the connection between the water injection channel and the water injection port.

[0022] The provision of the third sealing member makes it less likely for water leakage to occur during the water injection process.

[0023] A boss is provided in the cavity, a first channel is provided on the boss, and the first channel is communicated with the air intake channel.

[0024] The setting of the boss allows the gas to enter the cavity, and the overall bubble display effect is better. Compared with the prior art, which uses direct gas discharge from the bottom, the size and frequency of the gas discharge are difficult to be carefully calculated manually. It should be noted that during the operation, those skilled in the art need to generate N bubbles in N seconds to adjust the flow rate of carbon dioxide. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Embodiment 1:

[0029] Refer to the attached Figure 1-3 As shown, a bubble counter comprises a main body 1 , wherein the main body 1 comprises a shell 2 , a first joint 3 and a second joint 4 .

[0030] The shell 2 is hollow and transparent, and its upper end is connected and matched with the first joint 3, and its lower end is connected and matched with the second joint 4. The preferred connection method here is a threaded connection. A cavity 21 is provided in the shell 2, and a boss 211 is provided in the cavity 21. The boss 211 is provided with a first channel 212, and the first channel 212 is connected to the air inlet channel. The setting of the boss 211 allows the gas to enter the cavity 21, and the overall bubble display effect is better. Compared with the prior art, the size and frequency of the gas outlet are difficult to be carefully calculated manually. It should be noted that during the operation, those skilled in the art need to generate N bubbles in N seconds to adjust the flow rate of carbon dioxide.

[0031] In this embodiment, the housing 2 may be made of transparent glass or transparent plastic, and those skilled in the art may make the selection according to actual needs.

[0032] An air outlet channel 31 , a water injection channel 32 , a second one-way valve assembly 33 , an air outlet 34 , a water injection port 35 and a first restoring member 37 are provided in the first joint 3 .

[0033] The lower end of the first joint 3 is threadedly connected to the side wall of the housing 2, thereby achieving the connection effect between the first joint 3 and the housing 2. The threaded connection greatly increases the overall assembly efficiency. In order to improve the sealing effect between the housing 2 and the first joint 3, a first sealing member 51 is provided between the housing 2 and the first joint 3. The first sealing member 51 is preferably made of rubber.

[0034] The gas outlet 34 is located at the center of the upper end of the first joint 3. Here, the gas outlet 34 extends vertically toward the upper end. In order to make the gas outlet 34 more smooth, the size of the gas outlet 34 in this embodiment is larger than the size of the gas outlet channel 31. Furthermore, an external thread is also provided on the top of the first joint 3, which is connected to a water pipe or other device to achieve the communication effect of the overall gas flow channel.

[0035] One end of the air outlet channel 31 is connected to the cavity 21, achieving the communication effect between the air outlet channel 31 and the cavity 21. The other end of the air outlet channel 31 extends upward and is connected to the air outlet 34. In this embodiment, it is preferred to adopt an oblique extension setting, mainly considering the space utilization rate, while also meeting the normal air outlet, preventing the air outlet channel 31 from crossing with the water injection channel 32, and preventing the bubble counter from being discharged from the air outlet 34 along with the carbon dioxide gas during normal use, and failing to achieve the water injection effect. At this time, the injected water will not flow into the cavity; at the same time, since the air outlet 34 and the cavity 21 are not coaxially arranged, considering the overall space utilization rate, the initial channel is set obliquely. In addition, the air outlet channel 31 can also be connected by a vertical bend, or it can be extended upward in a spiral.

[0036] The second one-way valve assembly 33 is located and fixed in the first joint 3. The preferred solution here is that the second one-way valve assembly 33 and the first joint 3 are not coaxially arranged, and the second one-way valve assembly 33 is located on the right side of the lower end near the cavity 21. Since the second one-way valve assembly 33 is relatively large in size, the second one-way valve assembly 33 and the air outlet channel 31 do not intersect, one is on the left side and obliquely upward, and the other is on the right side, so different axis settings are adopted to reduce the overall spatial impact of the second one-way valve assembly 33. At the same time, the second one-way valve assembly 33 is easier to install and fix by adopting different axis settings, avoiding spatial overlap. Moreover, during the water injection process, the state of the water flow can be more intuitively observed, thereby improving the convenience of water injection.

[0037] A protrusion 36 is provided in the first joint 3, and the water injection channel 32 runs through the protrusion 36, so that during the water injection process, the water flow can better enter the cavity 21 through the protrusion 36. The second one-way valve assembly 33 cooperates with the protrusion 36 through the first reset member 37 to form a one-way valve effect, that is, only water or gas entering through the water injection channel 32 can also make the second one-way valve assembly 33 move downward, so that the first reset member 37 is compressed, and the external water can enter the cavity 21, achieving the effect of adding water. When the external force disappears, the first reset member 37 is reset, so that the second one-way valve assembly 33 and the protrusion 36 are firmly against each other to prevent gas leakage. Here, the second one-way valve assembly 33 is preferably a sealing pad made of rubber material, and the first reset member 37 is preferably a spring. As a result, the second one-way valve assembly 33 can only flow in one direction, including gas and liquid, and cannot be reversed from another direction.

[0038] One end of the water injection channel 32 is connected to the second one-way valve assembly 33, and the other end is connected to the water injection port 35. The water injection channel 32 also extends upward first, and then extends horizontally toward the outside of the first joint 3, so that there is no intersection between the water injection channel 32 and the air outlet channel 31, and the water that is not injected into the two will be discharged from the air outlet 34 along with the carbon dioxide gas. At the same time, this connection structure is more convenient in terms of processing. Here, those skilled in the art can also adjust the shape of the air outlet channel 31 and the water injection channel 32 according to actual needs, such as spiral, oblique, etc.

[0039] In addition, water is injected through the water injection port 35, and the operator can insert a small device such as a needle into the water injection port 35 to achieve the water injection effect. Further, a third sealing member 53 is provided at the connection between the water injection port 35 and the water injection channel 32. Since there is a certain air pressure difference between the cavity 21 and the external environment during the use of the bubble counter, if there is no third sealing member 53, part of the water will penetrate out during the water injection process and may spill on the operator, so the third sealing member 53 is added. Here, the third sealing member 53 can be a sealing ring.

[0040] In addition, it should be noted that the first connector 3 as a whole can be regarded as a one-way valve with a water injection structure, thereby achieving a good combination of the one-way valve, the connector, and the water injection structure, so that the entire first connector 3 fully utilizes the internal space structure within the size of the connector, increases the functions of the one-way valve and the water injection structure, and achieves the effect of miniaturization and easy assembly.

[0041] The upper end of the second connector 4 is threadedly connected to the outer wall of the shell 2. In order to better achieve the sealing effect between the second connector 4 and the shell 2, the second sealing member 52 is located between the second connector 4 and the shell 2, thereby enhancing the sealing effect. A first one-way valve assembly 41 and an air inlet 42 are provided in the second connector 4. The direction of the first one-way valve assembly 41 is only for the air inlet 42 to be conductive toward one side of the cavity 21, and the reverse direction is a cut-off state. Here, specifically, the first one-way valve assembly 41 cooperates with the second reset member 411 to achieve the effect of one-way conduction. One end of the second reset member 411 abuts against the first one-way valve assembly 41, and the other end abuts against the shell 2. In this embodiment, the first one-way valve assembly 41 is also preferably a sealing pad made of rubber material, and the second reset member 411 is preferably a spring, so that the first one-way valve assembly 41 can better achieve the one-way effect.

[0042] The air inlet 42 is connected to the pressure reducing valve, and the pressure reducing valve is used to connect the air inlet 42 and the carbon dioxide cylinder. Here, the second connector 4 is provided with an internal thread to facilitate the connection and fixation with the pressure reducing valve.

[0043] It should also be noted that the second connector 4 can also be regarded as a connector with a one-way valve function added. Compared with the prior art, this structure is simpler and more convenient to install.

[0044] With this structural setting, due to the setting of the first one-way valve assembly 41, the water in the cavity 21 will not flow back into the carbon dioxide cylinder through the air inlet 42, and the normal carbon dioxide gas can be discharged into the water cylinder through the air outlet 34. When it is necessary to inject water into the cavity 21, water can be injected through the water injection port 35, but due to the setting of the second one-way valve assembly 33, only external water can enter the cavity 21, and the gas in the cavity 21 cannot be discharged through the water injection channel 32. This structural setting makes it possible to achieve the effect of adding water by simply adding water to the water injection port 35 during normal use without stopping the operation of related equipment or performing disassembly operations, thereby satisfying the normal operation of the bubble counter.
