Description

Technical Field

[0001] The invention belongs to the technical field of water purifiers, and in particular, relates to a testing device for a filter element of a water purifier and a use method thereof. Background Art

[0002] The most important part of a water purifier is its internal filter element. The quality of the filter element directly determines the quality of the water purifier. After the water purifier filter element is improved or upgraded or mass-produced, the filter element needs to be extracted for testing. The filtration test is used to check whether the purified water index meets the standard. At present, the test is mainly done manually, which is inefficient. In addition, the manual test is mainly a single test, using a single test water sample for filtration, and the test is not comprehensive.

[0003] To this end, relevant technical personnel have designed a testing device as shown in CN115235978B, which drives the filter element and related structures to move to each sample device through a motor-driven screw to detect the filtration effect of each sample water after passing through the filter element to achieve the purpose of the test.

[0004] However, during the rotation of the motor, the filter element is also continuously moving. The device needs to control the motor to stop in time so that the corresponding structure can be aligned with the sample mechanism. At the same time, after aligning the sample mechanism, the sample mechanism needs to be controlled to extend for sample feeding, which puts higher requirements on the operator's operation. Summary of the invention

[0005] In view of the deficiencies in the prior art, an object of the present invention is to provide a testing device for a water purifier filter element and a method of using the same, so as to solve the technical problem mentioned in the above background technology that an operator needs to control the stopping timing of the motor and the extension of the sample mechanism during testing.

[0007] A testing device for a water purifier filter element, comprising a bottom plate, a driving motor, a driving assembly, a moving assembly, a water inlet assembly, a water outlet pipe, a pushing member, a clamping assembly, a water quality testing pen, a sample mechanism and a driven mechanism;

[0008] The driving motor is arranged on the bottom plate, the driving assembly is rotatably arranged on the bottom plate and connected to the driving motor, the moving assembly is slidably arranged on the bottom plate, and the driving assembly can intermittently drive the moving assembly to slide;

It should also be understood that the sealing assembly can close the bottom of the telescopic tube when the water inlet assembly is not inserted, and after the water inlet assembly is inserted to a certain depth, the water inlet assembly causes the sealing assembly to rotate and open the closure of the telescopic tube, and when the telescopic tube is shortened, before the telescopic tube leaves the water inlet assembly, the sealing assembly automatically resets to close the end of the telescopic tube.

[0014] Furthermore, the sealing assembly includes a hinge shaft, a sealing plate and an elastic connector; the sealing plate is hinged to the telescopic tube through the hinge shaft, the sealing plate is connected to the telescopic tube through the elastic connector, and the water inlet assembly can rotate the sealing plate by squeezing one side of the elastic connector on the sealing plate.

The squeeze plate is preferably an L-shaped plate, and the squeeze plate is set as an L-shaped plate, and the diversion of the bottom of the water inlet pipe after the squeeze plate is set as a straight plate is avoided to affect the outflow of the sample water.

[0017] Further, the driven assembly includes a driven fixed plate, a return spring and a driven wedge; the driven fixed plate is arranged on the bottom plate and connected to the driven wedge through the return spring; the driven wedge is slidably connected to the bottom plate and can slide toward the sample mechanism under the drive assembly. It should be understood that when the incomplete gear just releases the meshing with the rack, the cam still has a distance from the driven wedge.

[0018] Furthermore, the driving assembly is provided with a plurality of limit grooves on one side close to the driven wedge block, and the driven wedge block is also provided with a limit rod, and the sliding of the driven wedge block can cause the limit rod to be inserted into the limit groove. Through this structure, the accidental sliding phenomenon that may occur when the rack stops can be further limited.

[0024] S5, starting the pushing member to move the water inlet assembly and the water outlet pipe away from the filter element, so that the sample water therein flows out;

[0025] S6. Repeat S1-S5 until all sample tests are completed.

[0026] Compared with the prior art, the advantages of the present invention include:

[0027] In the present application, the moving component and the driven mechanism move alternately under the drive of the driving component, so that the water inlet component moves periodically and intermittently under each sample mechanism, and at the same time the driven mechanism extends periodically and intermittently, so that the water inlet component can open the sample mechanism after moving under each sample mechanism, allowing sample water to flow in, thereby causing the water inlet component to stop sliding under the sample mechanism, and the corresponding sample mechanism can spontaneously feed the sample water into the filter element, so that each stop position of the filter element is more accurate, and the sample water flows out spontaneously, thereby eliminating the need for the tester to confirm the stop position of the filter element and the opening and closing of the sample mechanism.

[0039] The embodiment of the present invention is intended to introduce and illustrate the structural composition of the testing device for the water purifier filter element and the matching relationship between the various components. Unless otherwise specified, the size, material and manufacturing process of each component in the testing device suitable for the water purifier filter element in the embodiment of the present invention can be selected according to the specific situation and are not specifically limited or explained here.

[0040] Further, in order to make the public have a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention. For those skilled in the art, the present invention can be fully understood without the description of these details.

[0041] Please also read Figure 1-Figure 3 , this embodiment provides a testing device for a water purifier filter element, including a bottom plate 1, a driving motor 2, a driving assembly 3, a moving assembly 4, a water inlet assembly 5, a water outlet pipe 61, a pushing member 62, a clamping assembly 7, a water quality detection pen 63, a sample mechanism 8 and a driven mechanism 9;

[0042] The driving motor 2 is arranged on the base plate 1, the driving component 3 is rotatably arranged on the base plate 1 and connected to the driving motor 2, the moving component 4 is slidably arranged on the base plate 1, and the driving component 3 can intermittently drive the moving component 4 to slide; it should be understood that the moving component 4 performs linear reciprocating motion, and the driving component 3 is driven by the driving motor 2.

[0043] The clamping assembly 7 is arranged on the moving assembly 4 and can clamp the filter element 10; that is, before starting the test, the filter element 10 to be tested is clamped and fixed on the moving assembly 4 by the clamping assembly 7. The water inlet assembly 5 and the water outlet pipe 61 are slidably arranged on the moving assembly 4 through the pushing member 62, and the water inlet assembly 5 and the water outlet pipe 61 can be connected to the filter element 10 by sliding, and the water quality detection pen 63 is inserted into the water outlet pipe 61;

[0044] Specifically, the pusher 62 is arranged on the moving assembly 4, and corresponds to the water inlet assembly 5 and the water outlet pipe 61 one by one. The pusher 62 is a machine capable of linear reciprocating pushing, such as a cylinder or a linear motor. In this embodiment, the pusher 62 is preferably a cylinder. The insertion end of the water inlet assembly 5 and the water outlet pipe 61 corresponding to the filter element 10 is made of a material with a certain flexibility. The water inlet assembly 5 and the water outlet pipe 61 can be inserted into the water inlet and the water outlet hole of the filter element 10 respectively under the push of the corresponding pusher 62, so that they are connected with the filter element 10. Furthermore, the insertion end of the water inlet assembly 5 and the water outlet pipe 61 can fill the water inlet or the water outlet of the filter element 10 through its own flexibility, further reducing the overflow of water.

[0045] There are multiple sample mechanisms 8, which can be telescopically arranged on the bottom plate 1. The driven mechanism 9 can be slidably arranged on the bottom plate 1. When the moving component 4 stops rotating, the driving component 3 can drive the driven mechanism 9 to slide toward the sample mechanism 8, so that the sample mechanism 8 extends toward the bottom plate 1, and the water inlet component 5 can open the sample mechanism 8 inserted therein.

[0046] Specifically, the driving motor 2 drives the driving component 3 to rotate continuously, first making the moving component 4 slide toward the next sample mechanism 8, then the moving component 4 stops sliding, and the driving component 3 drives the driven mechanism 9 to extend toward the bottom plate 1. When the moving component 4 drives the water inlet component 5 to be located below the sample mechanism 8, the extended sample mechanism 8 is inserted into the water inlet component 5, and the sample mechanism 8 is opened, so that the sample water in the sample mechanism 8 can flow into the water inlet component 5 and flow into the water outlet pipe 61 through the filter element 10, so that the water quality detection pen 63 can detect the filtered water through the filter element 10. It is worth mentioning that the driven mechanism 9 starts to slide a short time after the moving component 4 stops sliding. At the same time, the driven mechanism 9 starts to move away from the sample mechanism 8 a short time before the moving component 4 starts to move again, so that the sample mechanism 8 can close the channel and reset. In general, the moving component 4 and the driven mechanism 9 are driven by the driving component 3 to move alternately and periodically, and there is an alternating gap between the two. By controlling the distance that the moving component 4 moves each time, the moving component 4 can be moved periodically under the sample mechanism 8 to receive the sample water flowing into the sample mechanism 8. It is also worth noting that the moving component 4 needs to move twice to move from one sample mechanism 8 to another sample mechanism 8, thereby providing enough time to read the parameters and release the previous sample water.

[0047] In this embodiment, the clamping assembly 7 is two oppositely arranged reeds, through which the filter element 10 is clamped. The reeds can be arranged on both sides or around the filter element 10.

[0048] In the present application, the moving component 4 and the driven mechanism 9 move alternately under the drive of the driving component 3, so that the water inlet component 5 moves periodically and intermittently under each sample mechanism 8, and at the same time, the driven mechanism 9 extends periodically and intermittently, so that the water inlet component 5 can open the sample mechanism 8 after moving under each sample mechanism 8, so that the sample water flows in, thereby making the water inlet component 5 stop sliding after passing under the sample mechanism 8, and the corresponding sample mechanism 8 can spontaneously unload the sample water into the filter element 10, so that each stop position of the filter element 10 is more accurate, and the sample water flows out spontaneously, thereby eliminating the need for the tester to confirm the stop position of the filter element 10 and the opening and closing of the sample mechanism 8.

[0049] In other schemes, the moving assembly 4 includes a rack 41, a moving connecting rod 42 and a moving base 43; the rack 41 and the moving base 43 are connected by the moving connecting rod 42 and are respectively slidably connected to the bottom plate 1, the driving assembly 3 can intermittently drive the rack 41 to move, and the clamping assembly 7, the water inlet assembly 5, the water outlet pipe 61 and the pusher 62 are respectively arranged on the moving base 43. It should be understood that the rack 41 and the moving base 43 respectively make linear reciprocating motions, and the bottom plate 1 is provided with corresponding slide grooves. At the same time, the rack 41 and the moving base 43 can also be directly connected.

[0050] In other schemes, the driving assembly 3 includes a driving rod 31, an incomplete gear 32 and a cam 33; the driving rod is coaxially fixed on the output shaft of the driving motor 2, the incomplete gear 32 is coaxially fixed on the driving rod 31, and can mesh with the rack 41; the cam 33 is arranged on the driving rod 31, and can intermittently drive the driven mechanism 9 to move. It should be understood that when the incomplete gear 32 drives the rack 41 to move, the cam 33 does not contact the driven mechanism 9; when the cam 33 drives the driven mechanism 9 to move, the incomplete gear 32 does not contact the rack 41. The rack 41 and the driven mechanism 9 are moved successively by the alternating drive of the incomplete gear 32 and the cam 33.

[0051] In other schemes, the sample mechanism 8 includes a sample barrel 81, a fixing frame 82, a telescopic tube 83, a lifting and fixing plate 94, a supporting spring 85, a connecting plate 86, a lifting wedge 87 and a sealing assembly 88; the sample barrel 81 is arranged on the bottom plate 1 through the fixing frame 82, and the telescopic tube 83 is arranged at the bottom of the sample barrel 81 and is connected; the lifting and fixing plate 94 is arranged on the sample barrel 81, and is connected to the connecting plate 86 through the supporting spring 85, the connecting plate 86 is connected to the telescopic tube 83, and the lifting wedge 87 is fixed on the connecting plate 86, and the movement of the driven mechanism 9 can squeeze the lifting wedge 87 and stretch the supporting spring 85; the sealing assembly 88 is rotatably arranged on the bottom plate 1 of the telescopic tube 83, and can rotate to open the telescopic tube 83 after the water inlet assembly 5 is inserted.

[0052] It should be understood that the connecting plate 86 is connected to the telescopic end of the telescopic tube 83, and the height position of the telescopic tube 83 can be maintained by the restriction of the support spring 85. The driven mechanism 9 stretches the support spring 85, which drives the lifting wedge 87 to move downward to stretch the telescopic tube 83. In order to reduce the overall weight, a plurality of grooves can be provided on the lifting wedge 87. It should also be understood that when the sealing component 88 is not inserted into the water inlet component 5, it can seal the bottom of the telescopic tube 83. After being inserted into the water inlet component 5 to a certain depth, the water inlet component 5 causes the sealing component 88 to rotate and open the closure of the telescopic tube 83. When the telescopic tube 83 is shortened, before the telescopic tube 83 leaves the water inlet component 5, the sealing component 88 automatically resets to seal the end of the telescopic tube 83.

[0053] In other schemes, the sealing assembly 88 includes a hinge shaft 881, a sealing plate 882 and an elastic connector 883; the sealing plate 882 is hinged to the telescopic tube 83 through the hinge shaft 881, and the sealing plate 882 is connected to the telescopic tube 83 through the elastic connector 883. The water inlet assembly 5 can rotate the sealing plate 882 by squeezing one side of the elastic connector 883 of the sealing plate 882.

[0054] Specifically, the sealing plate 882 has margins on both sides of the hinge shaft 881, and the sealing plate 882 can resist the water pressure in the telescopic tube 83 through the support of the elastic connector 883, so that the sealing plate 882 closes the telescopic tube 83 before being squeezed by the water inlet assembly 5. The elastic connector 883 can be a spring or an elastic rope, etc. In order to reduce the occupied space, the elastic rope is selected in this embodiment.

[0055] In other schemes, the water inlet assembly 5 includes a water inlet pipe 51 and an extrusion plate 52; the water inlet pipe 51 is slidably disposed on the movable assembly 4, and the extrusion plate 52 is fixed in the water inlet pipe 51 and can squeeze the sealing plate 882 away from one end of the elastic connecting member 883.

[0056] The extrusion plate 52 is preferably an L-shaped plate, and the extrusion plate 52 is set as an L-shaped plate, and the diversion of the bottom of the water inlet pipe 51 after the extrusion plate 52 is set as a straight plate is avoided to affect the outflow of the sample water. It is worth mentioning that the water inlet pipe 51 and the water outlet pipe 61 both include a vertical pipe with a closed bottom and a plastic round tube connected to the bottom of the side, and are connected to both ends of the filter element 10 through the round tube.

[0057] In other embodiments, the driven mechanism 9 includes a driven component 91, a driven connecting plate 92 and a driven push plate 93; the driven component 91 is slidably disposed on the bottom plate 1, and the driving component 3 can periodically drive the driven component 91 to slide; the driven connecting plate 92 is slidably disposed on the bottom plate 1 and connected to the driven component 91, and the driven push plate 93 corresponds to the sample mechanism 8 one by one and is fixed on the driven connecting plate 92. Specifically, the rotation of the cam 33 drives the intermittent sliding of the driven component 91, and then drives the driven push plate 93 to squeeze the lifting wedge 87 of the sample mechanism 8,

[0058] In other embodiments, the driven assembly 91 includes a driven fixed plate 911, a return spring 912 and a driven wedge 913; the driven fixed plate 911 is provided on the bottom plate 1 and connected to the driven wedge 913 through the return spring 912; the driven wedge 913 is slidably connected to the bottom plate 1 and can slide toward the sample mechanism 8 under the drive of the driving assembly 3. Specifically, the cam 33 intermittently drives the driven wedge 913 to slide, and the sliding direction of the driven wedge 913 is perpendicular to the sliding direction of the rack 41. The driven wedge 913 is provided with inclined surfaces on both opposite sides, and the top of the inclined surface is provided with a chamfer. The cam 33 slides the driven wedge 913 by first squeezing the chamfer and then squeezing the inclined surface. At the same time, it should be understood that when the incomplete gear 32 is just released from the meshing with the rack 41, the cam 33 still has a distance from the driven wedge 913.

[0059] In other embodiments, a plurality of limiting grooves 411 are provided on the driving assembly 3 near the driven wedge block 913, and a limiting rod 94 is also provided on the driven wedge block 913. The sliding of the driven wedge block 913 can insert the limiting rod 94 into the limiting groove 411. Specifically, a plurality of limiting grooves 411 are provided on the rack 41, and this structure can further limit the accidental sliding phenomenon that may occur when the rack 41 stops.

[0060] A method for using a water purifier filter element testing device comprises the following steps:

[0061] S1, clamp the filter element 10 on the clamping assembly 7;

[0062] S2, start the pusher 62 to insert the water outlet pipe 61 and the water inlet assembly 5 into the filter element 10;

[0063] S3, start the motor;

[0064] S4, when the moving component 4 leaves the previous sample mechanism 8 and is between adjacent sample mechanisms 8, reading the parameters;

[0065] S5, start the pusher 62 to move the water inlet assembly 5 and the water outlet pipe 61 away from the filter element 10, so that the sample water inside flows out;

[0066] S6. Repeat S1-S5 until all sample tests are completed.

[0067] The above-mentioned water purifier filter element testing device and the use method thereof can save the energy of confirming the moving position of the filter element and manipulating the sample mechanism to discharge the material.

It cannot be determined that the specific implementation of the present invention is limited to these descriptions.
