Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and particularly relates to a detection device for a water purifier filter element. Background Art

[0002] With the continuous improvement of people's requirements for the quality of drinking water, the quality control of water purifier filter elements has become increasingly important. Filter element detection is a key link to ensure product quality and ensure that its filtration performance meets the standards. When traditional filter element detection devices clamp the filter element, they usually apply axial forces to both ends of the filter element to achieve the functions of sealing and clamping. However, this clamping method has obvious risks. During the process of applying axial forces, if the operation is improper or the force control is poor, it is very likely to cause the filter element to deform. Once the filter element is deformed, its internal filtration structure and pore distribution will be affected, thereby changing the filtration performance of the filter element, making the detection results unable to truly reflect the actual quality of the filter element, and seriously interfering with the accurate evaluation of the filter element quality. In addition, when the existing clamping device clamps the filter element, when the two clamping shafts are not concentric relative to each other, during the process of rotating and detecting the filter element, a torsional force will be generated on the filter element. This torsional force will further exacerbate the degree of deformation of the filter element, and also make the stress state of the filter element during the detection process complex, affecting the accuracy and reliability of the detection data. Summary of the Invention

[0008] Further, a first air supply port is provided on the first protective bladder, and a second air supply port is provided on the second protective bladder. Both the first protective bladder and the second protective bladder have a first deflated state and a second inflated state. By evacuating the first air supply port and the second air supply port, the first protective bladder and the second protective bladder are in the first state. By supplying air to the first air supply port and the second air supply port, the first protective bladder and the second protective bladder are in the second state.

[0012] Further, the support member includes a first support block and a second support block. The first support block and the second support block are fixedly provided in the detection cavity. The first support block and the second support block jointly support the filter element.

The driving source gradually drives the first clamping shaft and the second clamping shaft to approach each other, so that both the first clamping shaft and the second clamping shaft are inserted into the filter element. By providing a first protective bladder on the first clamping shaft and a second protective bladder on the second clamping shaft, the first protective bladder and the second protective bladder can contact the side wall of the filter element. When the driving source drives the first clamping shaft and the second clamping shaft to move along their own axes, the contact area between the first protective bladder and the second protective bladder and the inner wall of the filter element changes. By using the first protective bladder and the second protective bladder to block both ends of the filter element, the probability of deformation of the filter element is reduced. If the first clamping shaft and the second clamping shaft are in a non-coaxial state, the deformation forms of the first protective bladder and the second protective bladder change, thereby avoiding the generation of torsional force when the filter element rotates, and further improving the accuracy of detecting the filter element.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply indicates that the horizontal height of the first feature is less than that of the second feature.

[0022] As Figures 1 to 5 shown, a detection device for a water purifier filter element 160 provided by an embodiment of the present invention includes a detection box 110, a clamping member, a support member and a sealing member.

[0023] The detection box 110 has a detection cavity 111 with an upward opening. The detection cavity 111 is arranged with an upward opening to ensure that the detection cavity 111 can accommodate liquid.

[0024] The clamping member includes a first clamping shaft 120 and a second clamping shaft 130. The first clamping shaft 120 and the second clamping shaft 130 are coaxially arranged. A driving source is provided on the detection box 110. The driving source can drive the first clamping shaft 120 and the second clamping shaft 130 to approach or move away from each other simultaneously, and the driving source can also drive the first clamping shaft 120 and the second clamping shaft 130 to move synchronously along their own axis directions. Specifically, when the detection of the filter element 160 has not started, the distance between the first clamping shaft 120 and the second clamping shaft 130 is greater than the axial length of the filter element 160 to ensure that the filter element 160 can be placed between the first clamping shaft 120 and the second clamping shaft 130. When the filter element 160 is placed in the detection cavity 111, at this time, the detection cavity 111 is in a state without liquid. Then, the driving source is used to drive the first clamping shaft 120 and the second clamping shaft 130 to approach each other simultaneously. When the first clamping shaft 120 and the second clamping shaft 130 approach each other, one end of the first clamping shaft 120 is inserted into the interior of the filter element 160, and one end of the second clamping shaft 130 is inserted into the interior of the filter element 160. The driving source can also drive the first clamping shaft 120 and the second clamping shaft 130 to rotate.

[0025] The support member is used to support the filter element 160 to be stationary in its own axis direction. In the state where the support member supports the filter element 160, the filter element 160 will not undergo displacement in its own circumferential direction. Moreover, by adjusting the height of the support member, it is ensured that when the filter element 160 is supported by the support member, the first clamping shaft 120 and the second clamping shaft 130 can be inserted into the interior of the filter element 160.

[0026] The seal includes a first protective bladder 140 and a second protective bladder 150. The volumes of the first protective bladder 140 and the second protective bladder 150 can deform. The first protective bladder 140 is disposed on the first clamping shaft 120, and the second protective bladder 150 is disposed on the second clamping shaft 130. In the initial state, the volumes of the first protective bladder 140 and the second protective bladder 150 are in the minimum state, facilitating one end of the first clamping shaft 120 and the second clamping shaft 130 to be inserted into the filter element 160. When the ends of both the first clamping shaft 120 and the second clamping shaft 130 are inserted into the filter element 160, there is a gap between the first clamping shaft 120 and the second clamping shaft 130, and the volumes of the first protective bladder 140 and the second protective bladder 150 increase. The first protective bladder 140 and the second protective bladder 150 gradually abut against the inner sidewall of the filter element 160. At this time, the driving source simultaneously drives the first clamping shaft 120 and the second clamping shaft 130 to move synchronously along their own axial directions, thereby changing the area where the first protective bladder 140 and the second protective bladder 150 contact the inner sidewall of the filter element 160. When the volumes of the first protective bladder 140 and the second protective bladder 150 increase, liquid is injected into the detection chamber 111 to ensure that the liquid is in a state of submerging the filter element 160. At the same time, high-pressure gas is flushed into the filter element 160. By analyzing the condition of bubbles generated in the detection chamber 111, the quality of the filter element 160 is analyzed. At the same time, the driving source drives the first clamping shaft 120 and the second clamping shaft 130 to be in a rotating state, thereby observing the uniformity of bubble discharge of the filter element 160 in the circumferential direction.

[0027] For a filter element 160 detection device of the present invention, when it is necessary to detect the filter element 160, the filter element 160 is placed in the detection chamber 111. The filter element 160 entering the detection chamber 111 is supported by a support member, so that the filter element 160 is in a stable state in the detection chamber 111. The driving source gradually drives the first clamping shaft 120 and the second clamping shaft 130 to approach each other, so that both the first clamping shaft 120 and the second clamping shaft 130 are inserted into the filter element 160. By providing a first protective bladder 140 on the first clamping shaft 120 and a second protective bladder 150 on the second clamping shaft 130, the first protective bladder 140 and the second protective bladder 150 can contact the sidewall of the filter element 160. When the driving source drives the first clamping shaft 120 and the second clamping shaft 130 to move along their own axial directions, the area where the first protective bladder 140 and the second protective bladder 150 contact the inner sidewall of the filter element 160 changes. By using the first protective bladder 140 and the second protective bladder 150 to block both ends of the filter element 160, the probability of deformation of the filter element 160 is reduced. If the first clamping shaft 120 and the second clamping shaft 130 are in a non-coaxial state, the deformation forms of the first protective bladder 140 and the second protective bladder 150 change, thereby avoiding the generation of torsional force when the filter element 160 rotates, and further improving the accuracy of detecting the filter element 160.

[0028] In one embodiment, the seal further includes a first seal sleeve 210 and a second seal sleeve 220. One end of the first seal sleeve 210 is slidably and sealingly connected to the first clamping shaft 120, and the other end of the first seal sleeve 210 is sealingly connected to one end face of the filter element 160; one end of the second seal sleeve 220 is slidably and sealingly connected to the second clamping shaft 130, and the other end of the second seal sleeve 220 is sealingly connected to the other end face of the filter element 160. Specifically, the first seal sleeve 210 is slightly frustum-shaped, with a hollow interior. The first seal sleeve 210 has a first end with a smaller diameter and a second end with a larger diameter. The first seal sleeve 210 is coaxially arranged with the first clamping shaft 120. The first end of the first seal sleeve 210 is slidably and sealingly connected to the first clamping shaft 120, and the second end of the first seal sleeve 210 is sealingly connected to one end face of the filter element 160. To ensure that the second end of the first seal sleeve 210 can abut against the end face of the filter element 160, it is set that the diameter of the second end of the first seal sleeve 210 is less than or equal to the outer diameter of the filter element 160. The second seal sleeve 220 is slightly frustum-shaped, with a hollow interior. The second seal sleeve 220 has a third end with a smaller diameter and a fourth end with a larger diameter. The second seal sleeve 220 is coaxially arranged with the second clamping shaft 130. The third end of the second seal sleeve 220 is slidably and sealingly connected to the second clamping shaft 130, and the fourth end of the second seal sleeve 220 is sealingly connected to the other end face of the filter element 160. To ensure that the fourth end of the second seal sleeve 220 can abut against the end face of the filter element 160, it is set that the diameter of the fourth end of the second seal sleeve 220 is less than or equal to the outer diameter of the filter element 160. By providing the first seal sleeve 210 and the second seal sleeve 220, a closed first chamber 230 is formed between the inner side wall of the first seal sleeve 210 and one end face of the filter element 160, and a closed second chamber 240 is formed between the inner side wall of the second seal sleeve 220 and one end face of the filter element 160. In the initial state, the air pressures in the first chamber 230 and the second chamber 240 are at the state of standard atmospheric pressure. When supplying gas to the interior of the filter element 160, by providing the first seal sleeve 210 and the second seal sleeve 220, it is possible to prevent the liquid in the detection chamber 111 from directly contacting the first protective bladder 140 and the second protective bladder 150. The first chamber 230 and the second chamber 240 are transition chambers, which reduce the pressure difference between the interior of the filter element 160 and the liquid, and further improve the sealing performance between the first clamping shaft 120 and the filter element 160 and the sealing performance between the second clamping shaft 130 and the filter element 160.

[0029] In one embodiment, a plurality of first suction cups 250 are provided on the first sealing sleeve 210, and a first air extraction pipe is provided on each first suction cup 250. A first sealing ring is fixedly provided at the second end of the first sealing sleeve 210. The first sealing ring is made of flexible rubber. When the second end of the first sealing sleeve 210 abuts against the end of the filter element 160, the first sealing ring deforms, thereby improving the sealing performance between the second end and the filter element 160. A first communication ring is fixedly provided on the first sealing sleeve 210. The first communication ring simultaneously communicates with a plurality of first air extraction pipes. When the gas inside the plurality of first air extraction pipes is extracted, the plurality of first suction cups 250 can adsorb on the end face of the filter element 160. A plurality of second suction cups 260 are provided on the second sealing sleeve 220, and a second air extraction pipe is provided on each second suction cup 260. A second sealing ring is fixedly provided at the fourth end of the second sealing sleeve 220. The second sealing ring is made of flexible rubber. When the fourth end of the second sealing sleeve 220 abuts against the end of the filter element 160, the second sealing ring deforms, thereby improving the sealing performance between the fourth end and the filter element 160. A second communication ring is fixedly provided on the second sealing sleeve 220. The second communication ring simultaneously communicates with a plurality of second air extraction pipes. When the gas inside the plurality of second air extraction pipes is extracted, the plurality of second suction cups 260 can adsorb on the end face of the filter element 160. The plurality of first air extraction pipes and the plurality of second air extraction pipes can be simultaneously evacuated. By providing the first communication ring and the second communication ring, the convenience of extracting the gas inside the plurality of first air extraction pipes and the plurality of second air extraction pipes is improved.

[0030] In one embodiment, a first air supply port 310 is provided on the first protective bladder 140, and a second air supply port 320 is provided on the second protective bladder 150. Both the first protective bladder 140 and the second protective bladder 150 have a deflated first state and an inflated second state. In the initial state, both the first protective bladder 140 and the second protective bladder 150 are in the first state, which is convenient for inserting a part of the first protective bladder 140 and a part of the second protective bladder 150 into the filter element 160. When a part of the first protective bladder 140 and a part of the second protective bladder 150 are inserted into the filter element 160, air is simultaneously supplied to the first air supply port 310 and the second air supply port 320, so that the first protective bladder 140 and the second protective bladder 150 are simultaneously deformed to the second state. Further, the first protective bladder 140 and the second protective bladder 150 can be adjusted between the first state and the second state by evacuating or supplying air to the first air supply port 310 and the second air supply port 320, thereby facilitating the insertion or extraction of the first clamping shaft 120 and the second clamping shaft 130 into or out of the filter element 160.

[0031] In one embodiment, when detecting the filter element 160, it is necessary to inject high-pressure gas into the interior of the filter element 160, and then observe the condition of the gas leaking through the circumferential direction of the filter element 160. The first clamping shaft 120 has a first air supply channel 330 penetrating its own axis, and the second clamping shaft 130 has a second air supply channel 340 penetrating its own axis. When one end of the first clamping shaft 120 and one end of the second clamping shaft 130 are simultaneously inserted into the interior of the filter element 160, and after the first protective bladder 140 and the second protective bladder 150 are both adjusted to the second state, air is simultaneously supplied into the first air supply channel 330 and the second air supply channel 340, so that the interior of the filter element 160 is in a high-pressure state, and then the condition of the bubbles in the detection chamber 111 is observed.

[0032] In one embodiment, the appearance of the first protective bladder 140 is slightly in the shape of a circular sleeve. The first protective bladder 140 has an inner side wall and an outer side wall. A first connecting ring 350 is fixedly arranged on the inner side wall of the first protective bladder 140. The first connecting ring 350 is coaxially and fixedly connected to the first clamping shaft 120. When the first protective bladder 140 is in the second state, the outer side wall of the first protective bladder 140 is in a state of abutting against the inner side wall of the filter element 160. When the first clamping shaft 120 moves in the axial direction relative to the filter element 160, the inner and outer side walls of the first protective bladder 140 are exchanged, and moreover, the area of the outer side wall of the first protective bladder 140 in contact with the inner side wall of the filter element 160 changes.

[0033] Furthermore, the appearance of the second protective bladder 150 is slightly in the shape of a circular sleeve. The second protective bladder 150 has an inner side wall and an outer side wall. A second connecting ring 360 is fixedly arranged on the inner side wall of the second protective bladder 150. The second connecting ring 360 is coaxially and fixedly connected to the second clamping shaft 130. When the second protective bladder 150 is in the second state, the outer side wall of the second protective bladder 150 is in a state of abutting against the inner side wall of the filter element 160. When the second clamping shaft 130 moves in the axial direction relative to the filter element 160, the inner and outer side walls of the second protective bladder 150 are exchanged, and moreover, the area of the outer side wall of the second protective bladder 150 in contact with the inner side wall of the filter element 160 changes.

[0034] In one embodiment, a first air supply port 310 of the first protective bladder 140 communicates with a first air supply passage 330; the connection between the first air supply port 310 and the first air supply passage 330 penetrates through the first connection ring 350. Specifically, when the first clamping shaft 120 moves relative to the filter element 160, the inner and outer walls of the first protective bladder 140 will be exchanged. By arranging the connection position between the first air supply port 310 and the first air supply passage 330 on the first connection ring 350, the stability of the connection between the first air supply port 310 and the first air supply passage 330 is ensured. A second air supply port 320 of the second protective bladder 150 communicates with a second air supply passage 340, and the connection between the second air supply port 320 and the second air supply passage 340 penetrates through the second connection ring 360. Specifically, when the second clamping shaft 130 moves relative to the filter element 160, the inner and outer walls of the second protective bladder 150 will be exchanged. By arranging the connection position between the second air supply port 320 and the second air supply passage 340 on the second connection ring 360, the stability of the connection between the second air supply port 320 and the second air supply passage 340 is ensured.

[0035] In one embodiment, the support member includes a first support block 410 and a second support block 420, and the first support block 410 and the second support block 420 are fixedly arranged in the detection chamber 111. Specifically, the heights of the first support block 410 and the second support block 420 in the vertical direction are adjustable. The first support block 410 and the second support block 420 are block structures that can be telescoped in the vertical direction. The distance between the first support block 410 and the second support block 420 is equal to the length of the filter element 160 in the axial direction, ensuring that the first support block 410 and the second support block 420 can support the filter element 160. Moreover, when the first support block 410 and the second support block 420 support the filter element 160, the axis of the filter element 160 is substantially coaxial with the first clamping shaft 120 or the second clamping shaft 130, and the filter element 160 will not move in its own axial direction.

[0036] In one embodiment, the driving source includes a first driving cylinder 430, a second driving cylinder 440 and a driving motor. A first rotating disk 450 is fixedly connected to the first driving cylinder 430. The first rotating disk 450 is rotatably connected to the detection box 110. The first driving cylinder 430 has a power output shaft, and the power output shaft of the first driving cylinder 430 is coaxially and fixedly connected to the first clamping shaft 120. When the first driving cylinder 430 is started, the first clamping shaft 120 can move along its own axis. A second rotating disk 460 is fixedly connected to the second driving cylinder 440. The second rotating disk 460 is rotatably connected to the detection box 110. The second driving cylinder 440 has a power output shaft, and the power output shaft of the second driving cylinder 440 is coaxially and fixedly connected to the second clamping shaft 130. When the second driving cylinder 440 is started, the second clamping shaft 130 can move along its own axis. The first rotating disk 450, the second rotating disk 460 and the first clamping shaft 120 are coaxially arranged. The first rotating disk 450 and the second rotating disk 460 are arranged at intervals on the detection box 110. The driving motor is fixedly connected to the detection box 110. The driving motor has a power output shaft, and a driving gear is fixedly arranged on the power output shaft of the driving motor. A gear sleeve is fixedly arranged on the first rotating disk 450. The driving gear is always meshed with the gear sleeve. When the driving motor is started, through the meshing of the driving gear and the gear sleeve, the first rotating disk 450 rotates, thereby driving the filter element 160 to rotate in the detection cavity 111.
