Description

Technical Field

[0001] This utility model relates to the field of oral irrigator testing technology, and more specifically to an oral irrigator water pressure testing device. Background Technology

[0002] With increasing awareness of oral health, the market demand for water flossers, as a highly efficient and portable oral care device, continues to rise. One of the core performance indicators of water flossers is the water pressure at the outlet. Excessive water pressure can damage gum tissue, while insufficient water pressure will not achieve the desired cleaning effect. Therefore, in the manufacturing process of water flossers, accurate and consistent testing of the water pressure at the outlet is a key step in ensuring the consistency of product quality.

[0003] Currently, water pressure testing of oral irrigators is generally conducted manually. For example, the operator holds the oral irrigator and then assembles the water supply pipe and nozzle to the inlet and outlet of the oral irrigator. The connection depth and angle between the water supply pipe and the inlet depend entirely on the operator's feel. Different operators or the same operator in different test batches may have different connection force and position, which can easily lead to inconsistent connection results and thus errors in the test results, resulting in low accuracy of the water pressure test.

[0028] See Figure 1-4As shown, this embodiment discloses a water pressure testing device for a water flosser, which includes: a retainer 1, a testing platform 2, a water supply pipe 3a, a nozzle 3b, and a testing mechanism 4; the retainer 1 is provided with a slot 11 for engaging the water flosser; the retainer 1 is connected to the testing platform 2; the water supply pipe 3a and the nozzle 3b are slidably connected to the testing platform 2 and are respectively located at both ends of the slot 11, for connecting the water inlet and outlet of the water flosser; the testing mechanism 4 is connected to the nozzle 3b for detecting the water pressure at the outlet of the water flosser.

[0029] In practice, first, place the water flosser without nozzle 3b in the slot 11; then, move the water supply pipe 3a and nozzle 3b horizontally so that the water supply pipe 3a is inserted into the water inlet of the water flosser and the nozzle 3b is inserted into the water outlet of the water flosser; next, supply water to the water flosser through the water supply pipe 3a so that water enters the water flosser from the water inlet; then, start the water flosser so that the water inside the water flosser is sprayed out from the water outlet through nozzle 3b, and the detection mechanism 4 detects the water pressure of the water flosser, thus completing the water pressure test of the water flosser; finally, remove the water supply pipe 3a and nozzle 3b from the water flosser and reset them, waiting for the next water flosser to be tested.

[0030] The water pressure testing device for the oral irrigator in this embodiment achieves precise positioning of the oral irrigator through the card holder 1 with the slot 11 on the testing platform 2, avoiding displacement by manual handling. The water supply pipe 3a and the nozzle 3b are slidably connected to the testing platform 2 and correspond to the water inlet and outlet of the oral irrigator, achieving standardized connection and solving the problem of inconsistency in manual connection. Furthermore, the detection mechanism 4 is directly connected to the nozzle 3b to achieve real-time and accurate water pressure detection, avoiding human operation errors, ensuring the accuracy of test results and improving testing efficiency, which can meet the needs of large-scale production.

[0031] In a preferred embodiment, the card holder 1 has a first slot 12 and a second slot 13 at its two ends, respectively. The first slot 12 is located at one end of the card holder 1 corresponding to the water inlet of the water flosser, and the second slot 13 is located at one end of the card holder 1 corresponding to the water outlet of the water flosser. The first slot 12 and the second slot 13 are connected to the card slot 11. The arrangement of the first slot 12 and the second slot 13 facilitates the water supply pipe 3a and the nozzle 3b to extend from the card holder 1 into the card slot 11 to connect with the water flosser.

[0032] In a further embodiment, the water pressure testing device for the oral irrigator further includes: a first sliding component 5 and a second sliding component 6; the first sliding component 5 and the second sliding component 6 are fixedly connected to the testing platform 2 and are respectively located at both ends of the slot 11; the water supply pipe 3a and the nozzle 3b are respectively connected to the first sliding component 5 and the second sliding component 6. In specific implementation, the water supply pipe 3a is connected to the first sliding component 5, and the axis of the water supply pipe 3a is aligned with the center of the water inlet of the water flosser. Then, the water supply pipe 3a is installed on the first sliding component 5, so that when the water supply pipe 3a needs to move, it can slide relative to the test platform 2 with the support of the first sliding component 5, so as to approach the first slot 12 and insert into the water inlet to achieve docking with the water flosser, or move away from the first slot 12 and separate from the water inlet to avoid the loading and unloading of the water flosser. At the same time, the nozzle 3b is connected to the second sliding component 6, and the axis of the nozzle 3b is aligned with the center of the water outlet of the water flosser. Then, the nozzle 3b is installed on the second sliding component 6, so that when the nozzle 3b needs to move, it can slide relative to the test platform 2 with the support of the second sliding component 6, so as to approach the second slot 13 and insert into the water outlet to achieve docking with the water flosser, or move away from the second slot 13 and separate from the water outlet to avoid the loading and unloading of the water flosser.

[0033] In a further embodiment, the water pressure testing device for the oral irrigator further includes: two clamping fixtures 7; the two clamping fixtures 7 are fixedly connected to the testing platform 2, respectively located on the side of the first sliding component 5 and the second sliding component 6 that are far apart from each other, and are respectively connected to the first sliding component 5 and the second sliding component 6, for driving the first sliding component 5 and the second sliding component 6 to move closer to or away from the slot 11. When the water flosser needs to be connected, the operator operates the clamping fixture 7 near the first sliding component 5, causing the driving component of the clamping fixture 7 to push the movable component of the first sliding component 5 towards the slot 11, thereby moving the water supply pipe 3a closer to the water inlet of the water flosser. At the same time, the operator operates the clamping fixture 7 near the second sliding component 6, pushing the movable component of the second sliding component 6 towards the slot 11, moving the nozzle 3b closer to the water outlet of the water flosser, until the water supply pipe 3a and the nozzle 3b are inserted into the water inlet and outlet respectively. After the test is completed, the two clamping fixtures 7 are operated in reverse, and the driving component pulls the movable components of the first sliding component 5 and the second sliding component 6 away from the slot 11, so that the water supply pipe 3a and the nozzle 3b are disengaged from the water flosser, achieving reset. The clamping fixture 7 provides a stable push-pull force for the first sliding component 5 and the second sliding component 6. Compared with manual assembly, it can more evenly control the magnitude of the push force and the moving speed, avoiding damage to the water supply pipe 3a, nozzle 3b or water flosser due to excessive push force, or loose connection due to insufficient push force, thus ensuring the consistency of the connection between the water supply pipe 3a and nozzle 3b and the water flosser during the testing process. The two clamping fixtures 7 independently drive the corresponding sliding components, and the moving sequence and speed of the two sliding components can be flexibly adjusted according to the actual docking requirements, improving the convenience of docking operation.

[0034] In a further embodiment, the first sliding assembly 5 includes: a first slide rail 51 and a first slider 52; the first slide rail 51 is fixedly connected to the test platform 2, and the extension direction of the first slide rail 51 is parallel to the extension direction of the water supply pipe 3a; the first slider 52 is sleeved on the first slide rail 51, and the water supply pipe 3a is connected to the first slider 52; a clamping fixture 7 near the first sliding assembly 5 is connected to the first slider 52. During testing, the clamping fixture 7 pushes the first slider 52 to slide along the first slide rail 51 toward the slot 11, causing the water supply pipe 3a to approach and be inserted into the water inlet of the water flosser; after the test is completed, the clamping fixture 7 pulls the first slider 52 to slide in the opposite direction, causing the water supply pipe 3a to reset. The mating structure of the first slide rail 51 and the first slider 52 provides precise guidance for the movement of the water supply pipe 3a, ensuring that the water supply pipe 3a always moves in the preset direction and avoiding failure of the water supply pipe 3a to connect with the water inlet due to deviation in the movement direction. The extension direction of the first slide rail 51 is parallel to the extension direction of the water supply pipe 3a, so that the water supply pipe 3a will not deflect at an angle during the movement, ensuring the coaxiality of the water supply pipe 3a interface and the water inlet, improving the connection sealing performance, and reducing the risk of water leakage. The first slider 52 is sleeved on the first slide rail 51, with low sliding resistance and smooth operation. At the same time, it can effectively control the radial runout of the water supply pipe 3a, improve the accuracy of the connection between the water supply pipe 3a and the water inlet, and thus ensure the stability of the water supply during the test.

[0035] In a further embodiment, the second sliding assembly 6 includes: a second slide rail 61 and a second slider 62; the second slide rail 61 is fixedly connected to the test platform 2, and the extension direction of the second slide rail 61 is parallel to the extension direction of the nozzle 3b; the second slider 62 is sleeved on the second slide rail 61, and the nozzle 3b is connected to the second slider 62; a clamping fixture 7 near the second sliding assembly 6 is connected to the second slider 62. During testing, the clamping fixture 7 pushes the second slider 62 to slide along the second slide rail 61 toward the slot 11, and the nozzle 3b moves with the slider and inserts into the water outlet of the water flosser; after the test is completed, the clamping fixture 7 pulls the second slider 62 to slide in the opposite direction, and the nozzle 3b disengages from the water outlet and returns to its initial position. The cooperation between the second slide rail 61 and the second slider 62 provides a stable sliding path for the nozzle 3b, ensuring that the nozzle 3b always moves in the preset direction during docking and resetting, avoiding misalignment between the nozzle 3b and the water outlet due to directional deviation, and ensuring a high docking success rate. The extension direction of the second slide rail 61 is parallel to the extension direction of the nozzle 3b, so that the nozzle 3b keeps its axis unchanged during movement, ensuring the coaxiality of the nozzle 3b interface and the water outlet, reducing mechanical wear during docking, and improving the sealing effect to prevent water leakage from the docking point from affecting water pressure detection. The second slider 62 is sleeved on the second slide rail 61, with low sliding resistance and smooth operation, and can effectively control the radial runout of the nozzle 3b, improving the docking accuracy between the nozzle 3b and the water outlet, thereby ensuring the stability of water spraying during the test.

[0036] In a further embodiment, the second sliding assembly 6 further includes: a connecting block 63 and a detection tube 64; the detection tube 64 is connected to the second slider 62, and the extension direction of the detection tube 64 is perpendicular to the extension direction of the nozzle 3b; the connecting block 63 is connected to the end of the detection tube 64 near the slot 11, and the nozzle 3b is connected to the connecting block 63 and communicates with the detection tube 64; the detection mechanism 4 is disposed on the detection tube 64. The connecting block 63 is connected to the second slider 62 through the detection tube 64, so that the nozzle 3b is indirectly connected to the second slider 62. When the second slider 62 moves, it drives the detection tube 64 to move, the detection tube 64 drives the connecting block 63 to move, and the connecting block 63 drives the nozzle 3b to move closer to or further away from the slot 11. During testing, the water flow from the water flosser enters the detection tube 64 through the nozzle 3b, and the detection mechanism 4 senses the water pressure in the detection tube 64 in real time and feeds back the data.

[0037] In a preferred embodiment, the connecting block 63 has a three-way structure, with one end connected to the water outlet of the nozzle 3b, one end connected to the water inlet of the detection tube 64, and the other end used for water recovery. It can be understood that the detection tube 64 can serve as a branch of the water outlet, used only for detecting water pressure; water recovery relies on the recovery end of the connecting block 63. Specifically, after the water flow from the water flosser enters the connecting block 63 through the nozzle 3b, it naturally splits into two paths. One path, a small amount of water, enters the detection tube 64 to meet the water pressure data collection requirements of the detection mechanism 4. The other path, the main water flow, is directly discharged to a preset recovery container through the recovery end. This diversion design effectively avoids the impact and disturbance of the main water flow affecting the water flow state within the detection tube 64, reducing detection errors caused by water flow impact. Furthermore, the main water flow is quickly discharged through the recovery end, preventing water accumulation or eddies within the connecting block 63, further ensuring the stability of the water flow within the detection tube 64. This makes the detection data more closely match the actual water pressure of the water flosser, improving the accuracy of the test results.

[0038] In a further embodiment, the clamping fixture 7 includes: a mounting base 71, a push-pull rod 72, and a handle 73; the mounting base 71 is fixedly connected to the test platform 2, and the mounting base 71 is provided with a through hole 711; the push-pull rod 72 passes through the through hole 711, and the end of the push-pull rod 72 away from the mounting base 71 is fixedly connected to the first sliding component 5 or the second sliding component 6; the handle 73 is hinged to the end of the mounting base 71 away from the through hole 711, and the end of the push-pull rod 72 away from the slot 11 is hinged to the end of the handle 73 near the end of the handle 73 that is hinged to the mounting base 71. In practice, the operator presses down on the end of handle 73 away from the hinge point with mounting base 71. Handle 73 rotates around the hinge point with mounting base 71, pushing push-pull rod 72 along through perforation 711 towards slot 11 via leverage. This, in turn, moves the first sliding component 5 or the second sliding component 6 closer to the punch to complete the connection. After the test is completed, handle 73 is lifted upwards, and push-pull rod 72 moves in the opposite direction under the action of handle 73, pulling the sliding component away from slot 11 to reset. The handle 73, designed with leverage principle, allows the operator to push push-pull rod 72 with less force, reducing operational intensity. The perforation 711 on mounting base 71 provides stable guidance for push-pull rod 72, ensuring that push-pull rod 72 always moves in the preset direction, avoiding jamming or connection deviation of the sliding component due to displacement of push-pull rod 72. It is understood that in other embodiments, a push-pull cylinder can be used to replace mounting base 71, push-pull rod 72, and handle 73, depending on actual needs.

[0039] It is understandable that the water pressure test of the water flosser precedes the assembly of the nozzle 3b and the complete housing assembly process. During the testing phase, the housing on the side where the power supply component of the water flosser is located is not assembled. Therefore, in a further embodiment, the water pressure testing device for the water flosser also includes: a power supply mechanism 8; the power supply mechanism 8 is used to supply power to the water flosser so that the water entering the water flosser is sprayed out from the outlet. After the water flosser is placed in the slot 11 and the water supply pipe 3a and the nozzle 3b are connected, the operator starts the power supply mechanism 8. The power supply mechanism 8 contacts the electrodes of the water flosser through a preset power supply method to provide the water flosser with the power required for operation. After the water flosser is powered on, the internal water pump of the water flosser starts, pressurizes the water entering the interior and sprays it out from the outlet through the nozzle 3b; after the testing mechanism 4 completes the water pressure test, the power supply mechanism 8 is turned off, the power supply to the water flosser is stopped, the water flosser stops spraying water, and then the subsequent reset operation is performed. The power supply mechanism 8 provides a stable power supply 83 for the water flosser, ensuring that the water flosser can operate normally during the test, pressurize and spray water, and provide the necessary test conditions for water pressure testing. In addition, the power supply mechanism 8 can realize automated power supply control, reduce manual intervention, and ensure the uniformity of test conditions. At the same time, the power supply mechanism 8 can adjust the output voltage, current and other parameters according to the test requirements, adapt to different models of water flossers with different power supply requirements, and improve the versatility of the water pressure testing device for water flossers.

[0040] In a further embodiment, the power supply mechanism 8 includes: a lifting assembly 81, an electrode post 82, and a power supply 83; the electrode post 82 is located above the slot 11 and connected to the lifting assembly 81, and is used to supply power to the electrodes of the water flosser; the lifting assembly 81 is connected to the test platform 2, and is used to drive the electrode post 82 to perform lifting and lowering actions; the electrode post 82 is connected to the power supply 83. When the water flosser is placed in the slot 11, the lifting assembly 81 drives the electrode post 82 to move downward until the electrode post 82 makes close contact with the electrode contacts of the water flosser; then the power supply 83 is turned on, and the current is transmitted to the water flosser through the electrode post 82 to supply power to the water flosser; after the test is completed, the power supply 83 is first turned off, and then the lifting assembly 81 drives the electrode post 82 to move upward to reset, disengaging from contact with the water flosser. The precise contact between the electrode post 82 and the water flosser electrode ensures the stability of the power supply and avoids power interruption or unstable power supply voltage due to poor contact, which would affect the water pressure test results. The lifting component 81 can precisely control the descent height and pressure of the electrode post 82, avoiding damage to the water flosser shell due to excessive descent of the electrode post 82 or poor contact due to insufficient pressure, thus ensuring the safety and reliability of the testing process.

[0041] In a further embodiment, the power supply mechanism 8 further includes: a locking component 814 and a return spring 815; the return spring 815 is disposed within the lifting component 81 and is used to drive the lifting component 81 to return to its original position; the locking component 814 is used to lock the compressed state of the return spring 815 or release the lock of the return spring 815. When it is necessary for the electrode post 82 to maintain contact with the water flosser, the lifting component 81 can be manually or electrically driven to lower the electrode post 82, compressing the return spring 815 until the electrode post 82 descends to a preset height and contacts the water flosser motor. Then, the locking component 814 locks the lifting component 81, keeping the return spring 815 in a compressed state, and the electrode post 82 is stably powered. After the test is completed, the locking component 814 is controlled to release the lock, the return spring 815 releases its elastic potential energy, pushes the movable end of the lifting component 81 to rise, and drives the electrode post 82 to return to its original position and disengage from the water flosser. The reset spring 815 automatically drives the lifting assembly 81 to reset after the locking assembly 814 is unlocked, eliminating the need for additional power, simplifying the equipment structure and reducing energy consumption. The locking assembly 814 stably maintains the compression state of the reset spring 815, ensuring that the electrode post 82 remains in close contact with the water flosser electrode during testing, preventing the electrode post 82 from detaching due to accidental loosening of the lifting assembly 81, and ensuring the continuity and stability of power supply. Compared to relying solely on the lifting assembly 81's own power to maintain the contact state, the cooperation between the reset spring 815 and the locking assembly 814 reduces the load on the lifting assembly 81, extends its service life, and reduces the risk of test interruption due to lifting assembly 81 failure.

[0042] In a further embodiment, the lifting assembly 81 includes: a bracket 811, a fixed sleeve 812, and a movable guide rod 813; the bracket 811 is fixedly connected to the test platform 2, the fixed sleeve 812 is vertically fixed to the bracket 811, the inner wall of the fixed sleeve 812 is provided with a guide groove along the length direction (not shown in the figure), the movable guide rod 813 passes through the fixed sleeve 812 and can slide up and down along the fixed sleeve 812, the lower end of the movable guide rod 813 is connected to the electrode post 82 through the bracket 811, and the upper end extends out of the fixed sleeve 812; a limiting ring 8131 protrudes from the outer wall of the movable guide rod 813, and a reset spring 815 is provided between the fixed sleeve 812 and the limiting ring 8131; a locking assembly 814 is provided at the lower end of the fixed sleeve 812. When the movable guide rod 813 moves to the locking component 814, the locking component 814 engages with the movable guide rod 813, so that the movable guide rod 813 is maintained at a specified height and the return spring 815 is maintained in a compressed state; after the locking component 814 is unlocked, the movable guide rod 813 separates from the locking component 814, and the movable guide rod 813 is reset under the elastic action of the return spring 815.

[0043] In a preferred embodiment, the movable guide rod 813 is provided with a limiting part that engages with the locking component 814. The limiting part includes, but is not limited to, a limiting groove and a limiting protrusion. The locking component 814 includes, but is not limited to, a limiting protrusion, a limiting groove, and a limiting telescopic post. In this embodiment, the specific structure of the locking component 814 is not limited.

[0044] In a further embodiment, the power supply mechanism 8 further includes a voltmeter 84; the voltmeter 84 is electrically connected to the power supply 83. The voltmeter 84, being electrically connected to the power supply 83, can monitor the voltage value output from the power supply 83 to the electrode post 82 in real time, providing direct feedback on the working status of the power supply mechanism 8. When the voltage deviates from the rated operating voltage of the water flosser, such as being too high or too low, the operator can promptly detect and adjust the parameters of the power supply 83, avoiding unstable operation of the water flosser due to abnormal voltage, such as fluctuations in water pressure output or damage. Simultaneously, it ensures consistent power supply conditions for the water flosser during each test, providing stable power assurance for the accuracy of water pressure test results and reducing test errors caused by power supply problems.

[0045] In a further embodiment, the water pressure testing device for the oral irrigator also includes: a water tank 9; a water supply pipe 3a connected to the water tank 9, and a water supply pump (not shown) installed on the water supply pipe 3a. The water tank 9 provides a stable water source for the water supply pipe 3a, avoiding the impact of external water source pressure fluctuations on water supply stability; the water supply pump on the water supply pipe 3a can actively control the water supply pressure and flow rate, and can accurately adjust the water supply parameters according to the water intake requirements of different models of oral irrigators, ensuring sufficient water supply and stable pressure inside the oral irrigator, thereby ensuring the consistency and authenticity of the oral irrigator water pressure test.

[0046] In a preferred embodiment, the detection mechanism 4 is a pressure gauge. The pressure gauge can directly monitor the water pressure inside the detection tube 64 in real time, accurately reflect the actual water pressure at the outlet of the oral irrigator, and allow operators to quickly read the pressure value without complicated operations.

[0047] In a preferred embodiment, a valve 641 is provided at the end of the detection tube 64 furthest from the nozzle 3b. The valve 641 at this end allows control over the flow and flow rate of water within the detection tube 64: during testing, the valve 641 is opened to ensure smooth water flow through the detection mechanism 4, guaranteeing accurate pressure detection; when the test is completed or the water flosser needs to be replaced, the valve 641 is closed to prevent backflow or leakage of residual water in the detection tube 64, avoiding water waste and protecting the detection mechanism 4 from accidental damage in a waterless state; furthermore, adjusting the opening of the valve 641 allows for fine-tuning of the water flow rate within the detection tube 64, adapting to different precision testing requirements and enhancing the flexibility of the water pressure testing device for the water flosser.
