Description

Filter flask sealing performance detection equipment and method

Technical Field

The invention relates to the field of detection of the sealing performance of filter bottles, in particular to a device and a method for detecting the sealing performance of a filter bottle.

Background

The filter flask is widely used in the drinking water equipment industry as a filtering device for filtering impurities in water. The detection of the tightness of the filter flask is a more critical step for checking whether the filter flask can be normally used. If the sealing property of the filter bottle is not satisfactory, the filter bottle connected to the water path may leak water due to a defect in the air tightness when the filter bottle is used.

In the prior art, when the tightness of a filter flask is detected, a certain amount of gas needs to be introduced into the filter flask to form a certain pressure inside the filter flask. Then the filter flask that will be detected is placed in aqueous to make the connector of filter flask immerse in aqueous, whether rely on the naked eye of testing personnel to observe the aquatic at last and have the bubble to emerge. Although the prior art method can detect the tightness of the filter flask, the prior art method for detecting the tightness of the filter flask has many defects.

Firstly, when the leakproofness of filter flask is detected through the mode among the prior art, because need rely on the human eye of testing personnel to judge, consequently, every testing personnel can only detect the leakproofness of a filter flask at every turn, can't detect a plurality of filter flasks simultaneously. In addition, it is difficult to ensure the accuracy of the detection result depending on the observation result of the inspector, and one of the main reasons is that when a plurality of parts of one filter flask have a leak tightness defect, human eyes cannot simultaneously catch the water leakage at a plurality of positions of the filter flask in water, and particularly when the filter flask has a fine leak tightness defect, the fine leak tightness defect of the filter flask cannot be accurately detected by using the method of the prior art.

Secondly, the filter flask that needs to be detected among the prior art detects the filter flask and places the filter flask that is detected in aqueous, consequently, can adhere to remaining water stain on the filter flask that is detected, and remaining water stain if not eliminated, breed bacterium and peculiar smell very easily. Once such a filter bottle is installed on a drinking device that a user drinks, it will tend to affect the user's drinking safety and experience.

Furthermore, when the method in the prior art is used for detecting the tightness of the filter flask, no technical equipment or technical means is used for recording the tightness detection result of each filter flask. Therefore, once the product defect occurs in the filter bottle afterwards, the defect can not be checked

In addition, when the mode in the prior art is adopted to detect the filter flask, certain gas needs to be filled in the filter flask so as to ensure that certain pressure is formed in the filter flask. Because the filter element is arranged in the filter flask, the pressure in the filter flask can not be overlarge in order to avoid the damage of the overlarge pressure on the filter element in the filter flask and influence the service life of the filter element. And if the pressure in the filter flask is too small, after the filter flask filled with gas is placed in water, the water leakage phenomenon in the water is not obvious due to the too small pressure, so that the detection result of the sealing performance of the filter flask is influenced.

In addition, when the mode of the prior art is adopted to detect the tightness of the filter flask, a detector cannot accurately judge whether the detected filter flask can be used according to the amount of bubbles. In other words, when the prior art method is used to detect a filter bottle, although a detector can observe that a certain amount of bubbles are generated in water, the detected filter bottle may still be used, and the detector may determine that the filter bottle cannot be used, which may result in waste of resources.

It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for ease of description and simplicity of description, and do not indicate or imply that the referenced devices or components must be in a particular orientation, constructed and operated in a particular orientation, and thus the above terms are not to be construed as limiting the present invention.

It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.

Referring to fig. 1 to 10, a sealability testing apparatus for a filter flask according to a preferred embodiment of the present invention will be described in detail below, wherein the sealability testing apparatus for a filter flask includes an apparatus body 10, at least one sealing member 20, and a load cell 30, wherein the load cell 30 and the sealing member 20 are respectively mounted to the apparatus body 10. Each of the sealing members 20 can form a detection chamber 201 for mounting a filter bottle 800.

Referring to fig. 3, in one example of the invention, the filter flask 800 includes a filter flask body 801 and a filter flask adapter 802, wherein the filter flask adapter 802 is mounted to the filter flask body 801 to form a connection 804 between the filter flask adapter 802 and the filter flask body 801. The connection 804 between the filter bottle adapter 802 and the filter bottle body 801 sometimes has a leak-tight effect. At least two liquid flow ports 8020 are arranged at the bottom of the filter bottle connector 802 of the filter bottle 800, wherein at least one of the liquid flow ports 8020 is an inlet port 8021, and at least one of the liquid flow ports 8020 is an inlet port 8022. Furthermore, as will be appreciated by those skilled in the art, in the present invention, the filter flask body 801 includes a housing and a filter element disposed within the housing.

When the filter bottle 800 is placed in the detection chamber 201 of the device body 10, the inlet 8021 and the outlet 8022 of the filter bottle 300 can be hermetically disposed in the detection chamber 201, so that the detection chamber 201 forms a pressure difference with the inside of the filter bottle 800 after the detection chamber 201 is filled with a detection gas. Subsequently, by detecting the pressure change in the detection chamber 201, the airtightness of the other part of the filter bottle 800 can be detected.

It will be appreciated by those skilled in the art that the inlet 8021 and the outlet 8022 of the filter bottle 800 may be sealed before the filter bottle 800 is disposed in the detection chamber 201.

After the filter bottle 800 is placed in the detection chamber 201 of the apparatus body 10, a high pressure chamber 202 can be formed between the inner wall of the detection chamber 201 formed by the sealing member 20 and the outside of the filter bottle 800 by the sealing member 20, wherein the connection portion 804 of the filter bottle 800 is held in the high pressure chamber 202, and the liquid flow port 8020 of the filter bottle 800 is sealed with respect to the detection chamber 202. The high pressure chamber 202 can be in communication with an inflation member 900. When the tightness detection device of the filter bottle is operated, the gas charging part 900 charges the detection gas into the high-pressure chamber 202, and the gas pressure in the high-pressure chamber 202 reaches a detection pressure. When the filter bottle 800 is tested, the liquid flow port 8020 of the filter bottle 800 is simultaneously blocked from the high pressure chamber 202, so that a certain pressure difference is formed between the outer wall of the filter bottle 800 and the inner side of the filter bottle 80 after the high pressure chamber 202 is filled with the test gas. The pressure measuring unit 30 is connected to the high pressure chamber 202 to measure the pressure of the sensing gas in the high pressure chamber 202 in real time.

Referring to fig. 9, in one embodiment of the present invention, a quantity M of test gas is introduced into the high pressure chamber 202 during testing of the filter bottle 800. The pressure of the high pressure chamber 202 after filling with a certain amount M of the detection gas can be detected by the pressure measuring unit 30, for example, P1. Further, before the filter bottle 800 is tested, the pressure P2 inside the detection chamber 201 formed by the sealing member 20 after the detection chamber 201 is filled with the quantitative amount M of the detection gas can be obtained, and the pressure P3 inside the high pressure chamber 202 when the liquid flow port 8020 of the filter bottle 800 is not sealed with respect to the detection chamber 202 after the detection chamber 201 is filled with the quantitative amount M of the gas can also be obtained. By comparing the size of P1 with respect to the space between P2 and P3, the airtightness of the filter flask 800 to be tested can be judged. Specifically, when the filter bottle adapter 802 of the filter bottle 800 is airtight, P1 will be greater than P2 and P3; when the filter bottle connector 802 of the filter bottle 800 leaks air, the detection gas filled in the high-pressure chamber 202 enters the interior of the filter bottle, the volume of the space filled with the quantitative gas is increased, and the corresponding pressure is reduced, so that the defect of air tightness of the filter bottle 800 is determined by detecting that the pressure P1 in the high-pressure chamber 202 is greater than P2 and approaches P3. It can be understood by those skilled in the art that, in the present invention, the sensing gas filled in the gas filling part 900 is implemented as a clean gas, and the type of filling the sensing gas is not limited. Preferably, in the present invention, the inflating means 900 is implemented to include an air compressor, wherein the air compressor is capable of compressing air and of inflating the high pressure chamber 202 with air.

Furthermore, the sealing member 20 includes a first housing 21 and a second housing 22. The first cover 21 and the second cover 22 are respectively provided to the apparatus body 10, wherein the first cover 21 is sealably abutted to the second cover 22 to form the detection chamber 201 when the first cover 21 covers the second cover 22. Specifically, in the present invention, when the first cover 21 is closed to each other and sealed with respect to the second cover 22, the sealed detection chamber 201 is formed between the first cover 21 and the second cover 22. When the filter bottle 800 needs to be tested, the filter bottle 800 is only required to be installed in the first cover 21 or the second cover 22, then the first cover 21 and the second cover 22 are hermetically abutted, and the liquid flow port 8020 at the filter bottle joint 802 of the filter bottle 800 is simultaneously isolated from the high-pressure chamber 202, at this time, the testing chamber 201 is divided into the high-pressure chamber 202 and the internal space of the filter bottle 800 by the filter bottle 800. It is worth mentioning that, since the liquid flow port 8020 of the filter bottle 800 is sealed, the formed high-pressure chamber 202 cannot be directly communicated with the liquid flow port 8020 of the filter bottle 800, and therefore, after the detection gas is filled into the high-pressure chamber 202, if the filter bottle 800 has no air tightness defect, a pressure difference can be formed between the high-pressure chamber 202 and the interior of the filter bottle 800.

Referring to fig. 5 to 8, in one embodiment of the present invention, when the filter bottle 800 is tested, the filter bottle 800 may be first installed in the first or

second housing

21 or 22. The first and

second housings

21, 22 are then sealingly abutted to form the detection chamber 201. Subsequently, a quantitative amount M of the detection gas is filled into the detection chamber 201. Subsequently, the pressure P1 in the high pressure chamber 202 after filling the detection gas of the fixed amount M can be detected by the pressure measuring unit 30. Subsequently, by comparing the sizes of P1 with P2 and P3, the sealability of the filter bottle 800 can be determined.

In another embodiment of the present invention, a certain amount of detection gas can be further filled into the detection chamber 201 through the gas filling part 900. The pressure inside the sensing chamber 201 is also controlled by controlling the amount of sensing gas filled in the sensing chamber 201.

In order to test the filter bottle 800, the filter bottle 800 may be first mounted in the first cover 21 or the second cover 22. The first and

second housings

21, 22 are then sealingly abutted to form the detection chamber 201. Subsequently, a certain amount of detection gas is filled into the detection chamber 201 to stabilize the gas pressure in the detection chamber 201 to the detection pressure. Since the air pressure in the detection chamber 201 is stabilized to the detection pressure, the high pressure chamber 202 between the filter bottle 800 and the inner walls of the first and

second casings

21, 22 can form a high pressure.

It is worth mentioning that, in the present invention, the pressure of the detection pressure is greater than the atmospheric pressure. Therefore, the pressure in the high pressure chamber 202 is also greater than atmospheric pressure.

After the filter bottle 800 is placed in the inspection chamber 201 for inspection, if the filter bottle 800 has a defective sealing property, the inspection gas in the high pressure chamber 202 can only enter the interior of the filter bottle 800 from between the filter bottle body 801 and the filter bottle connector 802, and can overflow from the liquid flow port 8020 of the filter bottle 800.

In this embodiment, the liquid outlet 8020 of the filter bottle 800 installed in the detection chamber 201 directly communicates with the outside. Therefore, after a high-pressure environment is formed in the high-pressure chamber 202 and the pressure in the high-pressure chamber 202 is stabilized at the detection pressure, the airtightness of the filter bottle 800 can be known by observing the pressure in the high-pressure chamber 202 detected by the pressure measuring unit 30 and comparing the relationship between the pressure value detected by the pressure measuring unit 30 in real time and the detection pressure. For example, when the liquid outlet 8020 is overflowed by gas with a predetermined pressure, the pressure in the high-pressure chamber 202 detected by the pressure measuring unit 30 will gradually decrease, and accordingly, the connection 804 between the body 801 and the joint 802 of the filter bottle has a defect of tightness. When the connection 804 between the body 801 and the connector 802 of the filter bottle is free from the escape of the testing gas with the predetermined pressure, the pressure in the testing chamber 201 detected by the pressure measuring unit 30 will keep the testing pressure unchanged or slightly change, and there will be no or small sealing defect between the body 801 and the connector 802 of the filter bottle 800, which is not enough to affect the normal use of the filter bottle 800.

It is to be understood that in the present invention, the filter vial sealability testing apparatus does not use any liquid in testing the filter vial 800. The filter bottle 800 being tested avoids any residual water contamination with liquid. In addition, in the whole detection process, the subjective judgment of detection personnel is not needed, so that errors caused by human subjective factor intervention are eliminated.

It should be noted that, as can be seen from the above, when the filter bottle 800 is tested by the filter bottle tightness testing apparatus, high-pressure gas surrounds between the filter bottle body 801 and the first and second covers 21 and 22 of the filter bottle 800 and does not enter the interior of the filter bottle 800, so that the filter element inside the filter bottle 800 is not damaged by the high pressure applied, which is very important for testing the filter bottle 800.

Referring to fig. 4A and 4B, further, in the present invention, the first cover 21 and the second cover 22 are respectively provided at an upper portion and a lower portion of the apparatus body 10, in other words, the first cover 21 and the second cover 22 are provided opposite to each other in an up-down direction on the apparatus body 10. Therefore, when the first cover 21 and the second cover 22 are close to each other up and down, the first cover 21 and the second cover 22 are in sealed abutment up and down, thereby forming the sealed detection chamber 201. It will be understood by those skilled in the art that the relative positions of the first cover 21 and the second cover 22 may be implemented as left-right relative arrangement, or as relative arrangement in other directions, and the invention is not limited in this respect.

The manner of abutting the detection chamber 201, which forms a seal, between the first cover 21 and the second cover 22 includes: the detection chamber 201 sealed by the first cover 21 in a manner of covering the second cover 22 and the detection chamber 201 sealed by the first cover 21 in a manner of being inserted into the second cover 22 are not limited in this respect. In addition, the shapes of the first cover 21 and the second cover 22 are not important to the present invention, and the present invention is not limited in this respect.

Preferably, when the first cover 21 and the second cover 22 which are arranged opposite to each other in the up-and-down direction form the detection chamber 201, the filter bottle 800 can be pressed by the gravity of the first cover 21 arranged above, so that the sealing degree of the butt joint between the first cover 21 and the second cover 22 is enhanced. Especially, when the detection chamber 201 is filled with gas of a predetermined pressure, the first cover 21 disposed above can counteract a partial pressure of the gas in the detection chamber 201. In order to enable those skilled in the art to understand the present invention, in at least one embodiment of the present invention, only the first cover 21 and the second cover 22 are implemented to be disposed opposite to each other in the vertical direction, the first cover 21 is disposed above the main body 10, and the second cover 22 is disposed below the main body 10. Specifically, the first housing 21 forms a first accommodating cavity 210 and has a first opening 212 communicating with the first accommodating cavity 210. The second housing 22 defines a second accommodating cavity 220 and has a second opening 222 communicating with the second accommodating cavity 220. When the filter bottle 800 needs to be tested, the filter bottle 800 is fixed in the first containing cavity 210 or the second containing cavity 220. When the first cover 21 and the second cover 22 are then sealingly engaged, the first opening 212 of the first cover 21 and the second opening 222 of the second cover 22 are brought into close, sealing engagement with each other. The first accommodating cavity 210 and the second accommodating cavity 220 are communicated with each other and form the detection chamber 201.

It is understood that, in the present invention, the space formed by the detection chamber 201 is slightly larger than the volume of the filter bottle 800, so that after the first cover 21 and the second cover 22 are abutted, the filter bottle body 801 of the filter bottle 800 is pressed by the second cover 22, so that the bottom of the filter bottle joint 802 is pressed. Because the bottom of the filter bottle adapter 802 is provided with an elastic sealing element 803, the compressed filter bottle adapter 802 forces the elastic sealing element 803 to deform, so that the liquid flow port 8020 at the bottom of the filter bottle adapter 802 can be isolated from the high pressure chamber 202. That is, in the present invention, the first cover 21 and the second cover 22 which are disposed up and down can facilitate the first cover 21 to press the filter flask 800 during the downward movement.

Further, the sealing member 20 is further provided with a joint mounting portion 23 located in the detection chamber 201, wherein the joint mounting portion 23 is disposed at the bottom of the second cover 22. When the filter bottle 800 is attached to the connector attachment portion 23, the liquid flow port 8020 of the filter bottle 800 at the filter bottle connector 802 is hermetically sealed and fitted to the connector attachment portion. Subsequently, as the first cover 21 and the second cover 22 approach each other, the upper portion of the body 801 of the filter bottle 800 is pressed by the first cover 21, so that the filter bottle connector 802 of the filter bottle 800 is pressed against the connector mounting portion 23. Typically, the filter bottle adapter 802 of the filter bottle 800 is provided with the elastic sealing member 803, such as a rubber sealing ring, so that the fluid port 8020 at the filter bottle adapter 802 after being compressed will be isolated from the detection chamber 201. That is, at this time, the detection gas filled in the detection chamber 201 cannot enter the filter bottle 800 from the liquid flow port 8020 at the filter bottle connector 802. But only from between the filter flask body 801 and the filter flask adapter 802 of the filter flask 800.

Further, in the present embodiment, the second enclosure 22 is slidably provided to the apparatus body 10. Therefore, before the inspector needs to inspect the filter bottle 800, the second cover 22 may be first operated to vertically shift the second cover 22 relative to the first cover 21, so that the inspector can conveniently place the filter bottle 800 in the first accommodating cavity 210.

In the present embodiment, since the first cover 21 and the second cover 22 are provided to the device body 10 in a vertically opposed manner, and the filter bottle 800 is subjected to the sealing performance test, the elastic seal 803 at the filter bottle joint 802 is deformed while the filter bottle 800 is held by the joint attachment portion 23 by the gravity of the filter bottle 800 itself placed on the joint attachment portion 23, so that the elastic seal 803 is pressed against the joint attachment portion 23, and the liquid flow port 8020 is blocked from the test chamber 201.

In addition, since the filter bottle 800 is in the detection chamber 201, as the pressure of the detection gas in the detection chamber 201 rises to the detection pressure, a pressure difference will be formed between the filter bottle body 801 and the filter bottle connector 802 of the filter bottle 800, and the filter bottle connector 802 of the filter bottle 800 is pressed against the connector mounting portion 23 due to the pressure difference.

In the first embodiment of the present invention, the connector mounting portion 23 is provided with a mating groove 231, wherein after the filter bottle 800 is mounted in the detection chamber 201 and the filter bottle 800 is pressed by the first cover 21, the liquid flow port 8020 of the filter bottle 800 is pressed against the high pressure chamber 202 in a sealing manner, thereby preventing the detection gas from entering the filter bottle 800 from the liquid flow port 8020 when the airtightness of the filter bottle 800 is detected.

Referring to fig. 8, it is worth mentioning that, in another embodiment of the present invention, the joint mounting part 23 is provided with at least one air outlet 230. In this embodiment, the air outlet 230 is disposed at the bottom of the docking slot 231, and the inlet 8021 and the outlet 8022 of the filter bottle 800 are sealingly docked to the air outlet 230 after the filter bottle 800 is disposed in the detection chamber 201.

Preferably, in this embodiment, the air outlet 230 communicates with the docking slot 231. When the filter bottle 800 is mounted to the connector mount 23, the inlet 8021 and the outlet 8022 of the filter bottle connector 802 are sealingly mated with the air outlet 230 at the connector mount 23, and the filter bottle connector 802 of the filter bottle 800 is engaged with the mating groove 231. Preferably, in an embodiment of the present invention, the air outlet 230 is directly communicated with the external atmosphere. In another embodiment of the present invention, the other pressure measuring unit 30 included in the sealing performance testing apparatus of the filter bottle is hermetically coupled to the liquid outlet 8020 through the gas outlet 230, and the sealing performance of the filter bottle 800 can be determined by comparing the pressure of the gas flowing out from the gas outlet 230 with the testing pressure. Preferably, in the present invention, the air outlet 230 is directly communicated with the external atmosphere.

When the pressure of the detection gas filled in the detection chamber 201 reaches the detection pressure, the detection gas in the high-pressure chamber 202 can enter the filter bottle 800 from the connecting part 804 between the filter bottle body 801 and the filter bottle joint 802 of the filter bottle 800 and flow out from the liquid flow port 8020. The pressure measuring unit 30 can detect not only the air pressure in the high pressure chamber 202 but also a specific value of the air pressure in the high pressure chamber 202 after the air flowing out from the liquid flow port 8020 is relatively changed, so that the leakage amount of the filter bottle 800 can be known by the detection personnel. According to the leakage amount of the filter bottle 800, the sealing degree of the connecting part 804 between the filter bottle body 801 and the filter bottle joint 802 of the filter bottle 800 can be calibrated.

As will be appreciated by those skilled in the art, the filter bottle 800 can still be used with minor defects in the seal between the body 801 and the fitting 802 of the filter bottle 800. Therefore, whether the filter bottle 800 to be detected can be normally used or not can be more accurately judged by the filter bottle tightness detection device. For example, in the present invention, the high pressure chamber 202 may be filled with gas until the detection pressure of the detection gas in the high pressure chamber 202 is stabilized at 0.6MPa, and then by detecting the detection gas pressure at the liquid flow port 8020, when the pressure measuring unit 30 detects that the reduction amount of the detection gas pressure in the high pressure chamber 202 exceeds 0.003MPa after the gas flows out from the liquid flow port 8020, the non-compliance of the filter bottle 800 may be judged.

In addition, when a tester uses the tightness testing device of the filter bottle to test the filter bottle 800, the tester can calibrate the tightness of the filter bottle 800 at different levels. For example, when the detection pressure of the detection gas filled in the high pressure chamber 202 is stabilized at 0.6MPa and the pressure measuring unit 30 detects that the reduction amount of the detection gas pressure in the high pressure chamber 202 is between 0.002MPa and 0.003MPa, the detector can calibrate the sealing performance of the filter bottle 800 to a lowest level; when the pressure measuring unit 30 detects that the reduction amount of the pressure of the detection gas in the high pressure chamber 202 is between 0.001MPa and 0.002MPa, the detector may calibrate the sealability of the filter bottle 800 to another lowest level.

That is, after the sealing performance detecting apparatus of the filter flask according to the present invention is used, it is possible to detect whether the filter flask 800 meets the use requirement, and to accurately determine which level the sealing performance of the filter flask 800 is at, thereby providing reference data for the replacement cycle of the filter flask 800.

It is worth mentioning that, in the present embodiment, the detection pressure is implemented to be 0.5Mpa to 0.7 Mpa. It is worth noting that in the present invention, when the detection pressure is too high, the connection portion 804 of the filter bottle 800 located in the high pressure chamber 202 may be broken, thereby damaging the filter bottle 800. When the detected pressure is too small, a small change in the pressure in the high pressure chamber 202 cannot be accurately detected, and thus, a false determination may be caused.

Further, the filter bottle sealing performance testing apparatus further includes at least a purifying member 40, wherein the purifying member 40 is disposed on the apparatus body 10, and the purifying member 40 can be communicated with the second sealing chamber 220 of the second housing 22. When the first opening 212 of the first housing 21 is hermetically abutted against the second opening 222 of the second housing 22, the detection gas filled by the inflating member 900 can enter the detection chamber 201 formed by the first housing 21 and the second housing 22 after being purified by the purifying member 40.

It can be understood by those skilled in the art that since the sensing gas filled in the sensing chamber 201 has been purified by the purifying part 40, the sealing performance testing apparatus of the filter bottle does not contaminate the filter bottle 800 when testing the filter bottle 800.

Preferably, in the present invention, the air charging part 900 is implemented as an air compressor, and the cleaning part 40 is implemented as an air cleaning part.

Further, the filter flask sealability testing apparatus includes an electric part 50, wherein the electric part 50 is provided to the apparatus body 10. The electric appliance unit 50 includes a warning member 51, wherein the warning member 51 is disposed on the apparatus body 10 and connected to the load cell 30. When the sealing performance detection device of the filter bottle detects the filter bottle 800, the pressure measuring unit 30 measures the air pressure of the liquid flow opening 8020 of the filter bottle 800, and can determine whether the air pressure of the liquid flow opening 8020 meets a predetermined air pressure. The warning means 51 can further automatically give an alarm based on the determination result.

It can be understood by those skilled in the art that the warning member 51 can be implemented as a warning light, wherein the warning member 51 can form different warning lights according to the determination result of the load cell 30, so that the inspector can determine whether the filter flask 800 to be inspected meets the requirements according to the formed warning lights. In addition, the warning part 51 may also be implemented as other devices capable of warning the inspector, such as a sound-emitting part, and the invention is not limited in this respect.

Referring to fig. 10, preferably, the electric part 50 includes a voltage stabilizing part 52 and a display part 53, wherein the voltage stabilizing part 52 is provided to the apparatus body and is communicated with the purifying part 40. The pressure stabilizing member 52 can stabilize the detection pressure formed by the detection gas in the high pressure chamber 202 at a specific value. The display unit 53 is connected to the load cell 30, and is capable of displaying the detection result by the load cell 30, so that the inspector can observe the magnitude of the pressure in the high pressure chamber 202 from the display unit 53.

More preferably, the pressure measuring unit 30 is communicatively connected to the display unit 53, wherein the display unit 53 is capable of displaying the detection result formed by the pressure measuring unit 30 on the display unit 53 at the same time, so that the pressure of the liquid outlet 8020 of the filter bottle 800 can be known by the detector from the display unit 53.

The filter bottle sealing performance detecting apparatus further comprises a driving part 60, wherein the driving elevating unit 61 comprises the driving elevating unit 61, wherein the driving elevating unit 61 is provided to the apparatus body 10. The sealing member 20 is drivably connected to the driving elevating unit 61, so that the sealing member 20 can form the detection chamber 201 after the sealing member 20 is driven by the driving elevating unit 61.

Specifically, in an embodiment of the present invention, the first cover 21 of the sealing member 20 is drivably connected to the driving elevating unit 61. Specifically, when the driving lifting unit 61 is activated to work, the driving lifting unit 61 can drive the first opening 212 of the first cover 21 to move close to the second opening 222 of the second cover 22, and make the first opening 212 of the first cover 21 sealingly abut against the second opening 222 of the second cover 22. The first enclosure 21 and the second enclosure 22 after sealed docking form the detection chamber 201. When the driving lifting unit 61 is closed, the driving lifting unit 61 drives the first cover 21 to move the first opening 212 of the first cover 21 away from the second opening 222 of the second cover 22, so that the first cover 21 and the second cover 22 form a placing space 203. The inspector can attach the filter bottle 800 to the connector attachment portion 23 of the second cover 22 through the placement space 203, so that the filter bottle 800 can be attached to the second cover 22.

It should be noted that, after the filter bottle 800 to be detected is mounted on the joint mounting portion 23 of the second cover 22, the first cover 21 can be driven to press the filter bottle 800 by driving the driving elevating unit 61. The pressure applied by the drive lift unit 61 causes the filter bottle 800 to be held in the detection chamber 201. And the pressure exerted by the drive lift unit 61 on the filter bottle 800 causes the filter bottle adapter 802 of the filter bottle 800 to remain blocked from the high pressure chamber 202. Therefore, when the detection chamber 201 is filled with the detection gas of a predetermined pressure through the gas filling member 900, the detection gas does not enter the filter bottle 800 from the liquid flow port 8020 at the filter bottle connector 802.

It will be understood by those skilled in the art that the driving elevating unit 61 may be implemented as a cylinder and at least one slide rail provided on the apparatus body 10, and particularly, when the first housing 21 is up-down drivingly connected to the driving elevating unit 61, the driving elevating unit 61 is implemented to include at least one elevating slide rail and at least one cylinder.

Further, the electric part 50 includes a controller 54, wherein the driving elevating unit 61 is controllably connected to the controller 54, so that the driving elevating unit 61 is controlled by the controller 54.

Further, the filter bottle sealing performance detecting apparatus includes at least one security component 70, wherein the security component 70 is disposed on the apparatus body 10. The security component 70 is connected to the controller 54. The security component 70 can detect whether detection personnel appear in the placing space 203 or not, and a corresponding detection result is formed. The controller 54 performs corresponding actions according to the detection result, such as driving the driving lifting unit 61 to stop working.

Specifically, if the driving elevating unit 61 is in an opened state when the inspector is putting the filter flask 800 from the putting space 203 to the second cover 22. The security component 70 detects that the arm of the inspector is present in the placing space 203 and forms a detection result related to the closing of the driving elevating unit 61. The driving elevating unit 61 is driven to be turned off by the detection result. Therefore, the first cover 21 does not move in a direction to approach the second cover 22. In this way, it is possible to prevent a detection person from being crushed by the first cover 21 when detecting a filter flask.

The security component 70 may be implemented as an image capturing device, at least one light detecting device such as a grating, etc., and the invention is not limited in this respect.

It is worth mentioning that, in the present invention, the sealing performance detecting apparatus of the filter flask includes a plurality of the sealing members 20, wherein the plurality of the sealing members 20 are respectively drivably connected to the driving elevating unit 61. Specifically, the first housing 21 of each sealing member 20 is drivably connected to the driving elevating unit 61, so that the plurality of sealing members 20 can be simultaneously driven to move away from the second housing 22 and close to the second housing 22. It is understood that the sealing performance detecting apparatus for filter bottle may also include a plurality of the driving elevating units 61, wherein the first housing 21 of each of the sealing members 20 is drivably installed to each of the driving elevating units 61. In order to enable those skilled in the art to understand the present invention, at least one example of the present invention is described by taking only an example in which the first cover 21 of a plurality of the sealing members 20 is drivably connected to one driving elevating unit 61, and the present invention is not limited in this respect.

Further, the driving part 60 includes a driving sliding unit 62, wherein the driving sliding unit 62 is provided to the apparatus body 10, and the second cover 22 of each sealing part 20 is slidably coupled to the apparatus body 10 through the driving sliding unit 62. When the second cover 22 is driven by the driving sliding unit 62 to slide, the second cover 22 is displaced with respect to the first cover 21. For example, in the embodiment of the present invention, when the first cover 21 is provided to slide up and down with respect to the second cover 22, the second cover 22 is provided to be slidable back and forth on the apparatus body 10. That is, when the inspector needs to attach the filter bottle 800 to be inspected to the first cover 22, the controller 54 is operated to move the second cover 22 forward to approach the inspector, and when the inspection chamber 201 needs to be formed to seal the filter bottle 800, the controller 54 is controlled to move the second cover 22 rearward away from the inspector and vertically align with the first cover 21, so that the second cover 22 can be sealingly abutted to the first cover 21 to form the inspection chamber 201 when the second cover 22 is driven to move downward.

Further, the inflating member 900 can simultaneously inflate the detection chamber 201 formed by the plurality of sealing members 20 with gas. When a plurality of filter bottles 800 need to be detected, the gas-filled part 900 is used to fill detection gas into the detection chamber 201 in which a plurality of filter bottles 800 to be detected are placed to simultaneously detect a plurality of filter bottles 800.

When a plurality of filter bottles 800 need to be tested, a tester can mount each filter bottle 800 on the joint mounting portion 23 of the second cover 22 of the sealing member 20. Then, the gas is filled into the detection chamber 201 through the gas filling part 900 for detection. In the present invention, the sealability detection apparatus of a filter flask includes a plurality of the load cells 30, wherein each of the load cells 30 is communicated with each of the load cells 30 through the air outlet 230 of the joint mounting part 23, respectively. By the mode, one detector can simultaneously detect the sealing performance of a plurality of filter bottles 800, so that the efficiency of detecting the sealing performance of the filter bottles 800 can be correspondingly improved.

It should be noted that, in the present invention, the device for detecting the leak tightness of a filter flask further includes the gas filling member 900. That is, in the present invention, the inflating means 900 is communicated with the sensing chamber 201 of the sealing means 20. When the filter bottle sealability testing apparatus is activated to test the filter bottle 800, the gas filling member 900 automatically fills the test gas into the test chamber 201 as the tested filter bottle 800 is mounted to the connector mounting portion 23 and the high pressure chamber 202 is formed, so that a high pressure environment is formed in the high pressure chamber 202 between the filter bottle body 801 and the sealing member 20 of the tested filter bottle 800, and a pressure difference is formed between the filter bottle body 801 and the fluid port 8020.

Further, the electric appliance part 50 further includes a flow control member 55, wherein the flow control member 55 is disposed at the apparatus body 10, and the flow control member 55 is respectively communicated with the first housing 21 of each sealing member 20 and is simultaneously communicated with the first receiving space 210 of the first housing 21. The flow control member 55 may be butted against the air charge member 900 to be able to control a communication state between the air charge member 900 and the first accommodation space 210. Specifically, when the flow control part 55 is activated, the inflation part 900 can inflate the detection gas into the first accommodation space 210; when the flow control member 55 is closed, the air filling member 900 is blocked from the first accommodation space 210.

Preferably, the flow control member 55 is connected to the controller 54, wherein the flow control member 55 is automatically controllable connected to the controller 54. Specifically, after the first cover 21 is driven by the driving lifting unit 61 to form the detection chamber 201 with the second cover 22, the controller 54 can automatically control the flow control member 55 to start. When the first housing 21 is not driven by the driving lifting unit 61 to form the detection chamber 201 with the second housing 22, the controller 54 can automatically control the flow control member 55 to close.

Preferably, in the present invention, the step 1102 includes the steps of:

11021: communicating the detection chamber 202 with an inflation member 900;

11022: the detection chamber 202 and the liquid flow port 8020 are separated by pressing the filter flask connector 802 against a connector mounting portion 23 of the second cover 22; and

11023: the detection chamber 202 is filled with detection gas through the gas-filled part, so that the pressure difference is formed between the detection chamber 202 formed by the body 801 of the filter bottle 800 and a sealing part 20 and the liquid flow port 8020 of the filter bottle 800.

The step 1103 is implemented as:

11030: the pressure in the sensing chamber 202 is sensed by a pressure cell 30.
