DETAILED DESCRIPTION OF EMBODIMENT

First Embodiment

Referring toFIGS.1to3, a bubble counter is provided, which may include a body1, and the body1includes a housing2, a first connector3and a second connector4.

The housing2is hollow and transparent, an upper end of the housing2is connected and cooperates with the first connector3, and a lower end of the housing2is connected and cooperates with the second connector4. In a preferable embodiment, the above connection is a screw connection. The housing2is provided with a cavity21therein. A boss211is disposed in the cavity21. The boss211is provided with a first channel212therein. The first channel212connects with a gas inlet channel. The arrangement of the boss211allows gas to enter the cavity21through the boss211, and thus an overall bubble display effect is better compared with a related art, in which gas enters from the lower end of the housing directly, and a volume and a frequency of the gas are difficult to be carefully calculated by hand. It should be noted that, in an operation process of the present disclosure, the skilled in the art can adjust a flow rate of carbon dioxide gas based on determining N bubbles generated in N seconds.

In the embodiment, the housing2may be made of transparent glass or transparent plastic, which can be selected by the skilled in the art according to actual requirements.

The first connector3is provided therein with a gas outlet channel31, a water inlet channel32, a second check valve (also referred to as one-way valve)33, a gas outlet34, and a water inlet35.

A lower end of the first connector3is in threaded connection with an outer wall of the housing2, so that the connection between the first connector3and the housing2is realized, and an overall assembly efficiency is greatly increased by the threaded connection. Further, in order to improve a sealing effect between the housing2and the first connector3, a first sealing member51is provided between the housing2and the first connector3. The first sealing member51is preferably made of rubber.

The gas outlet34is arranged at a center of an upper end of the first connector3. Specifically, the gas outlet34extends vertically toward the upper end of the first connector3, and a size of the gas outlet34in the embodiment is larger than that of the gas outlet channel31in order to make the gas outlet34smoother. Furthermore, an upper part of the first connector3is further provided with an external thread, through which the first connector is connected to devices such as a water pipe to thereby realize a communication effect of a whole gas channel.

An end of the gas outlet channel31is connected to the cavity21, which realizes a communication effect between the gas outlet channel31and the cavity21. Another end of the gas outlet channel31extends upward and connects with the gas outlet34. In the embodiment as a preferable embodiment, the gas outlet channel adopts an inclined-upward extension arrangement, mainly considering a space utilization rate, and at the same time, it is necessary to ensure normal smoothness of gas outlet, so as to prevent the gas outlet channel31from crossing with the water inlet channel32and thereby causing gas leakage. Further, since the gas outlet34and the cavity21are coaxially arranged, an incline treatment is required to realize a communication effect between the gas outlet channel31and the gas outlet34. In addition, the gas outlet channel31may be vertically bent for connection, or may be spirally extended upward.

The second check valve33is fixed in the first connector3. In the embodiment, as a prefer embodiment, the second check valve33is non-coaxially arranged with the first connector3, and the second check valve33is arranged in a direction near the lower end and a right side of the first connector3. The second check valve33has a large volume, the second check valve33is isolated from the outlet channel31(i.e., there is no intersection between the second check valve33and the outlet channel31), the outlet channel31is inclined upward at a left side of the first connector3, and the second check valve33is arranged on the right side of the first connector3, so different axes arrangement are adopted for the second check valve33and the first connector3, thereby reducing the influence of the second check valve33on a whole space. Meanwhile, with the different axes arrangements, the second check valve33is more convenient to be installed and fixed, and in a process of water injection, a state of water flow can be observed more intuitively, thus improving the convenience of water injection. In order to improve a fixing effect between the second check valve33and the first connector3, the first connector3is provided with a slot36therein, the second check valve33is provided with a protrusion331therein corresponding to the slot36, and the protrusion331extends into the slot36. The arrangement of the slot36and the protrusion331causes a better fixing effect of the second check valve33during a fixing process thereof. Furthermore, in order to improve a gas tightness of the connection between the second check valve33and the body1, a sealing ring may be sleeved on the second check valve33, to prevent gas leakage, and the sealing ring can be specifically sleeved on the protrusion331. It should be noted that, for the second check valve33, flow can be performed in one direction, including flow of gas and liquid, but flow cannot be performed in the other direction, which can be obtained from the related art, so a specific structure of the check valve will not be described in the embodiment.

An end of the water inlet channel32is connected to the second check valve33, and another end is connected with the water inlet35. The water inlet channel32extends upward first, and then laterally and horizontally extends to an outside of the first connector3, so that the water inlet channel32and the gas outlet31are independent from each other (there is no intersection between the water inlet channel32and the gas outlet channel31), and thus there is no gas leakage between the water inlet channel32and the gas outlet channel31. Moreover, this connection structure is more convenient in a processing manner. Alternatively, the skilled in the art can also adjust shapes of the gas outlet channel31and the water inlet channel32according to actual requirements, such as a spiral shape, an inclined shape and so on.

In addition, water is injected through the water inlet35, and the operator can make a small device such as a needle tube access to the water inlet35to realize a water injection effect. Furthermore, a third sealing member53is disposed at a connection between the water inlet35and the water inlet channel32. When the bubble counter is used, there is a certain gas pressure difference between the cavity21and an external environment, and if there is no third sealing member53, part of water will seep out during a water injection process and may spill on the operator, therefore, the third sealing member53is added.

An upper end of the second connector4is in threaded connection with the outer wall of the housing2. Herein, in order to realize a better sealing effect between the second connector4and the housing2, a second sealing member52is arranged between the second connector4and the housing2, for enhancing the sealing effect. A first check valve41and a gas inlet42are arranged in the second connector4. The first check valve41is turned on in a direction from the gas inlet42toward the cavity21, and an opposite direction thereof corresponds a turned off state. In the embodiment, in order to better fix the first check valve41, the first check valve41is arranged between the housing2and the second connector4, so that the first check valve41is firmly fixed in the body1. Herein, preferably, a reset member411of the first check valve41abuts against the housing2, so that the first check valve41can be fixed more firmly and stably, and a backflow phenomenon is not easy to occur. Herein, preferably, the reset member411is a spring.

The gas inlet42is connected to a pressure reducing valve, which is used to connect the gas inlet42with a carbon dioxide cylinder. Herein, the second connector4is provided with an internal thread, which is convenient to connect and fix with the pressure reducing valve.

With the above structure, due to the arrangement of the first check valve41, the water in the cavity21will not flow back into the carbon dioxide cylinder through the gas inlet42, whereas carbon dioxide gas can be discharged into a water tank through the gas outlet34. When water needs to be injected into the cavity21, water can be injected through the water inlet35; further, due to the arrangement of the second check valve33, only external water can enter the cavity21, and the gas in the cavity21cannot be discharged through the water inlet channel32. According to the structure, in a normal use process, it is not required to stop the operation of related apparatus or perform a disassembling operation, and the effect of adding water can be achieved only by adding water to the water inlet35, thereby achieving a normal operation of the bubble counter.
