Description

Technical fields:

[0001] This utility model relates to a device for testing water flossers, and more particularly to a workpiece testing device, which is especially used for aging tests of flushing products such as water purifiers and dental flossers. Background technology:

[0002] A water flosser is an oral care tool that uses water or air to clean between teeth, the gingival sulcus, and periodontal pockets. It removes food debris and plaque through physical rinsing and is an effective supplement to traditional toothbrushes and dental floss.

[0003] After the oral irrigator is manufactured, it needs to undergo some tests, including cleaning power, water pressure, flow rate and aging tests.

[0004] Currently, the only known aging test device for water flossers is the Chinese patent "An Aging Test Device for Water Flossers" (publication number CN218213225U), which includes a cabinet and a central control box located on the side of the cabinet. Inside the cabinet, the test chamber and the rear compartment are separated by two crossbeams and two mounting back panels. Several water flosser fixing mechanisms are also installed in the test chamber. The water flosser fixing mechanisms include a bottle bottom fixing unit installed on a channel steel bracket and a bottle neck fixing unit installed on the crossbeam.

[0005] The Chinese patent "A Test Fixture" (publication number CN217520742U) includes a chassis and at least one fixing component. The chassis includes a water storage chamber and at least one storage chamber. The chassis has a water supply port connected to the water storage chamber. The end of the water supply port away from the water storage chamber is used to connect to the main body of the water flosser to be tested. The at least one storage chamber is disposed on the periphery of the water storage chamber and is used to accommodate the water flosser to be tested. At least one fixing component is installed in the at least one storage chamber. The fixing component includes two opposing clamping plates. The two clamping plates cooperate to clamp several main bodies of the water flosser to be tested. Both clamping plates are perpendicular to the axial direction of the water flosser to be tested.

[0006] Both of the aforementioned testing devices suffer from complex structures and low efficiency in loading or unloading the products under test during testing. Summary of the Invention:

[0007] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a workpiece testing device with a simple structure and reasonable design, which is conducive to improving testing efficiency.

[0008] The technical solution adopted in this utility model is as follows:

[0009] The workpiece testing equipment of this utility model is characterized in that: it includes a frame and a circulating production line that can move relatively cyclically on the frame. The circulating production line is provided with multiple positioning holes for positioning and placing the workpiece to be tested for aging. The aging test of the workpiece is completed after the workpiece moves on the circulating production line for a set time.

[0010] Preferably, the frame has a fixedly installed annular water tank. The lower part of the workpiece placed in the positioning hole extends into the annular water tank. The annular water tank can hold test water with a water level exceeding the water inlet end of the lower part of the workpiece, so that the water inlet end of the workpiece placed in the positioning hole can draw water from the annular water tank and drain water from the water outlet end into the annular water tank. The aging test of the workpiece is completed after the test workpiece moves on the circulating production line for a set time.

[0011] Preferably, the above-mentioned annular water tank is an annular water tank, and the circulating production line is a circulating conveyor belt located above the annular water tank.

[0012] Preferably, the above-mentioned annular water tank is a circular annular water tank, and the circulating flow line is a rotating plate located above the circular annular water tank.

[0013] Preferably, the above-mentioned annular water tank includes a base plate horizontally fixed on the frame, an inner ring plate and an outer ring plate vertically spaced on the outer periphery of the upper surface of the base plate, a closed cavity for holding test water is formed between the inner ring plate and the outer ring plate, and a rotatable turntable is provided at the center of the upper surface of the base plate, and a rotating plate that covers the inner ring plate and the outer ring plate and is rotatable relative to it is fixedly connected to the turntable.

[0014] Preferably, a positioning sleeve is installed in the positioning hole. The positioning sleeve is grooved and has at least one through hole communicating with the annular water tank.

[0015] Preferably, the positioning sleeve is made of silicone or rubber material.

[0016] Preferably, the upper outer periphery of the positioning sleeve is provided with an annular flange, which is positioned in conjunction with the positioning hole on the circulating production line. The inner periphery of the positioning sleeve is provided with a sink groove and a through hole. A bottom hole is provided at the bottom of the sink groove. Both the through hole and the bottom hole are connected to the annular water tank. The through hole and the bottom hole are lower than the upper edge of the annular water tank so that the test water contained in the annular water tank can exceed the lower water inlet end of the workpiece.

[0017] Preferably, the workpiece is positioned in the settling tank, the water inlet end of the workpiece is connected to the bottom hole of the tank, and the water outlet end of the workpiece is connected to a drain pipe, which passes through the through hole and extends into the annular water tank.

[0018] Preferably, the positioning hole is covered with a soundproof cover that can cover the workpiece.

[0019] Preferably, the central part of the upper surface of the rotating plate has a plurality of trapezoidal support plates arranged in a circular array. The lower bottom edge of each trapezoidal support plate is fixedly connected to the upper surface of the rotating plate, and the upper bottom edge of each trapezoidal support plate is fixedly connected to the lower surface of an upper plate.

[0020] The working method of the workpiece testing equipment described in this utility model is characterized by: testing water being filled in an annular water tank, and ensuring that the water level of the testing water in the annular water tank exceeds the water inlet end of the workpiece (such as a tooth piercing device) placed in the positioning hole; the first station of the annular water tank serves as the inlet end of the testing equipment, and the side of the first station of the annular water tank serves as the outlet end of the testing equipment; the outlet end is close to the inlet end and runs in the opposite direction to the running direction of the circulating production line.

[0021] During operation, the circulating production line continuously moves in a circular motion relative to the annular water tank. Workpieces that have been started and are in operation (such as a toothed brush) are placed one after another into the positioning hole at the feed end of the testing equipment. The water inlet end of the workpiece draws water from the annular water tank and the water outlet end drains water into the annular water tank, realizing the water intake and spraying of the workpiece. As the circulating production line continues to run, each workpiece achieves the action of water intake and spraying on the entire circulating production line. The aging test of the workpiece is completed when it has circulated on the circulating production line for one or less time.

[0022] This utility model workpiece testing equipment features a circular assembly line layout, simple structure, and low manufacturing cost. It also facilitates and speeds up the loading (placing the workpiece into the positioning hole) and unloading (removing the workpiece from the positioning hole) of the workpiece to be tested, thereby improving testing efficiency. Furthermore, it can be integrated into the preceding or following processes to form a continuous production line, which can further enhance production efficiency. Attached image description:

[0030] The method of this utility model will be further described in detail below with reference to the embodiments. It should be noted that the protection scope of this utility model should include, but is not limited to, the technical content disclosed in this embodiment.

[0031] This utility model workpiece testing equipment includes a fixedly installed annular water tank 1 and a circulating assembly line 2 that can move relatively cyclically on the annular water tank. The circulating assembly line 2 is similar in shape to the annular water tank 1. The circulating assembly line 2 runs cyclically along the trajectory of the annular water tank 1. The time it takes to complete one revolution along the trajectory of the annular water tank 1 can be determined by the time required for testing products such as water flossers or rinsers (which can be referred to as workpieces or products to be tested). For example, if it is necessary to keep the water flosser working for 5 minutes (i.e., the water flosser continuously absorbs and drains water within 5 minutes), then the time for the circulating assembly line 2 to complete one revolution along the trajectory of the annular water tank 1 can be set to 5 minutes. The adjustment of the running speed of the circulating assembly line 2 is existing technology and will not be described in detail here.

[0032] One embodiment is (Example 1), such as Figure 1 As shown, the annular water tank is a ring-shaped water tank, and the circulating production line is a circulating conveyor belt located above the annular water tank. The annular water tank can be a rectangular water tank, an elliptical water tank, or a racetrack-shaped water tank, and the circulating conveyor belt can be a roller conveyor belt, a chain conveyor belt, etc. The shape of the circulating conveyor belt is similar to that of the annular water tank.

[0033] Another embodiment is (Example 2), such as Figure 2-6 As shown, the annular water tank is a circular water tank, and the circulating flow line is a rotating plate 7 located above the circular water tank. The rotating plate can be circular or a rectangle with rounded corners on all four sides, and the rotation axis of the rotating plate is consistent with the axis of the circular water tank.

[0034] Multiple positioning holes 4 are provided on the circulating production line 2 for positioning and placing rinsing products (which can be called workpieces or products to be tested) such as water flossers 3. The positioning holes 4 can be used to directly position the water flossers so that the water flossers can be positioned securely (the water flossers and the positioning holes can be transition fit to achieve secure positioning), or other positioning components (such as the positioning sleeves below) can be installed in the positioning holes 4.

[0035] The lower part of the water flosser placed in the positioning hole 4 extends into the annular water tank 1. The annular water tank can hold test water (which can be pure water or water with cleaning solution, etc.) with a water level exceeding the water inlet end of the lower part of the water flosser. The water flosser mainly includes a pump mechanism, a lower suction pipe and an upper spray pipe. The water inlet end can be the inlet of the suction pipe, and the water outlet end can be the outlet of the spray pipe. When the pump mechanism of the water flosser is started, the water inlet end 301 of the water flosser placed in the positioning hole can draw water from the annular water tank (i.e., water can be drawn through the suction pipe) and drain water from the water outlet end 302 into the annular water tank (i.e., water can be sprayed through the spray pipe; a drain pipe is installed on the spray pipe later, and the water outlet end is the outlet of the drain pipe).

[0036] Because the water inlet 301 of the water flosser can draw water from the annular water tank, and the water outlet 302 of the water flosser drains water into the annular water tank, the water in the annular water tank can be recycled.

[0037] In Example 2, the annular water tank includes a base plate 101 horizontally fixed on a frame, an inner ring plate 102 and an outer ring plate 103 vertically spaced on the outer periphery of the upper surface of the base plate. The base plate 101, the inner ring plate 102 and the outer ring plate 103 can be made of transparent material (glass or acrylic sheet). A closed cavity 5 for holding test water is formed between the inner ring plate and the outer ring plate. A rotatable turntable 6 is provided at the center of the upper surface of the base plate 101. A rotating plate 7, which is fixedly connected to the turntable and covers the inner ring plate and the outer ring plate and can rotate relative to it, can be a turntable driven by the output of a motor, or the turntable can be an annular internal gear ring, with the gear at the output of the motor meshing with the internal gear ring to drive the rotation.

[0038] A positioning sleeve 8 is installed in the positioning hole 4. The positioning sleeve 8 is grooved and its lower part extends into the annular water tank. The grooved positioning sleeve 8 is provided with at least one through hole communicating with the annular water tank. The positioning sleeve can be made of a buffer material such as silicone or rubber. The positioning sleeve is made of a buffer material such as silicone or rubber to avoid damaging the surface of the water flosser during the test. In addition, since the water flosser vibrates frequently when it is working, the positioning sleeve 8 is made of rubber or silicone, which helps to buffer and reduce noise.

[0039] The upper outer periphery of the positioning sleeve 8 is provided with an annular flange 801, which is positioned in conjunction with the positioning hole on the circulating production line. The inner periphery of the positioning sleeve is provided with a groove 804 and a through hole 802. The bottom of the groove 804 is provided with a bottom hole 803. Both the through hole 802 and the bottom hole 803 are connected to the annular water tank 1. The through hole 802 and the bottom hole 803 are lower than the upper edge of the annular water tank so that the test water contained in the annular water tank can exceed the lower water inlet end of the water flosser (the lower part of the water flosser is inserted into the positioning sleeve).

[0040] To achieve smooth water intake (pumping) and drainage (spraying), a water flosser 3 is positioned in the settling tank 804. The water inlet 301 at the bottom of the water flosser is connected to the bottom hole 803 of the tank. The water outlet (spray pipe outlet) of the water flosser is connected to a drain pipe 9 (the drain pipe 9 can be a plastic hose; the drain pipe 9 is not a component of the water flosser itself, but is temporarily attached to the water outlet of the water flosser for testing purposes). The drain pipe 9 passes through the through hole 802 and extends into the annular water tank. When the water level exceeds the water inlet 301 of the water flosser, the water flosser 3 can draw water, and then drain the water into the annular water tank through the drain pipe 9 to achieve water recycling.

[0041] To reduce noise, a soundproof cover 10 is provided on the positioning hole 4 to cover the water flosser (this soundproof cover 10 is not necessary). The soundproof cover 10 can be made of materials such as plastic or stainless steel, preferably transparent plastic, so as to facilitate the observation of the water flosser's operation. When the opening of the soundproof cover 10 is fitted with the upper outer periphery of the positioning sleeve 8 made of rubber or silicone (the two are in a transition fit), the sound insulation effect can be further improved. In addition, since the water flosser vibrates frequently when it is working, the positioning sleeve 8 made of rubber or silicone is beneficial to buffer and reduce noise.

[0042] To increase the support effect and strength of the rotating plate, multiple trapezoidal support plates 11 are arranged in a circular array at the center of the upper surface of the rotating plate 7. The lower bottom edge of each trapezoidal support plate 11 is fixedly connected to the upper surface of the rotating plate, and the upper bottom edge of each trapezoidal support plate is fixedly connected to the lower surface of an upper plate 12.

[0043] The present invention describes the working method of the workpiece testing equipment, wherein test water is contained in an annular water tank, and the water level of the test water contained in the annular water tank is ensured to exceed the water inlet end of the lower part of the rinsing device placed in the positioning hole. The first station of the annular water tank is used as the inlet end of the testing equipment, and the side of the first station of the annular water tank is used as the outlet end of the testing equipment. The outlet end is close to the inlet end and is opposite to the running direction of the circulating production line.

[0044] During operation, the circulating production line continuously moves in a circular motion relative to the annular water tank. One after another, the activated water flossers are placed into the positioning holes at the feed end of the testing equipment. The water flosser draws water from the annular water tank at its inlet end and drains water into the annular water tank from its outlet end, thus realizing the water intake and spraying action of the water flosser. As the circulating production line continues to run, each water flosser achieves the water intake and spraying action throughout the entire circulating production line.

[0045] In Example 2, assuming each person's action on the production line is t seconds, and the aging time is T, the aforementioned rotating workbench (i.e., rotating plate 7, etc.) takes more than T to complete one rotation. Therefore, the production line worker only needs to turn on the water flosser to be tested, place it on the rotating workbench, and rotate it once or less. Another production line worker can then directly remove it to perform subsequent actions (such as quality inspection of other performance aspects). This eliminates the need to waste waiting time or place the water flosser to be tested on the specialized aging equipment mentioned in the background technology, greatly saving time and improving work efficiency.

[0046] Let n be the number of water flossers to be tested that need to be placed in the test equipment of this application. If the width of the workstation occupied by each water flosser product to be tested is l, then the diameter D of the rotating worktable is:

[0047] For example: t = 10 seconds, aging time T = 5 minutes = 300 seconds, then Because placing and removing the water flosser to be tested requires two operators, the required quantity is greater than this. This additional quantity can be determined based on the distance between the two operators. For example, if the distance between the two operators is exactly at 90° of the circular rotating worktable (i.e., they are offset by 90 degrees around the circumference), then n can be set to 40. Assuming the station width for each product is l = 100mm, then... Therefore, the diameter of this rotating worktable can be designed to be greater than 1273mm, such as 1300mm or 1350mm.

[0048] Of course, if D is too large, it will waste production space. A multi-layered structure (let's say m layers) can be designed on the rotating worktable. Each test flosser on each layer rotates m times before being removed. Then, the working diameter D of the rotating worktable is:

[0049] This utility model workpiece testing equipment features a circulating production line layout, simple structure, and low manufacturing cost. It also facilitates and speeds up the loading (placing the punch into the positioning hole) and unloading (removing the punch from the positioning hole) of the punch to be tested, which helps improve testing efficiency. Furthermore, it can be connected to the preceding or following processes to form a continuous production line, thereby improving production efficiency.

[0050] This equipment can also be used to test other products that require pumping and drainage.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
