Description

Technical Field

[0001] This application relates to the field of oral irrigator testing technology, and more particularly to a testing fixture. Background Technology

[0002] During the production of water flossers, aging tests are typically conducted to determine their lifespan. It is well known that water flossers have a built-in safety mechanism that stops working when tilted to a certain angle. However, in current aging tests, the water flosser is prone to interrupting the test due to excessive tilting, resulting in low testing efficiency. Summary of the Invention

[0003] The purpose of this application is to provide a testing fixture that addresses the problem of low testing efficiency caused by frequent interruptions in the aging test process of existing water flossers.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] This application embodiment provides a testing fixture for aging testing of a water flosser, the testing fixture comprising:

[0006] A chassis includes a water storage chamber and at least one storage chamber. The chassis has a water supply port communicating with the water storage chamber. One end of the water supply port, away from the water storage chamber, is used to communicate with the main unit of the oral irrigator to be tested. The at least one storage chamber is located around the periphery of the water storage chamber and is used to house the oral irrigator to be tested.

[0007] At least one fixing component is installed in the at least one placement cavity, and the fixing component includes two opposing clamping plates. The two clamping plates cooperate to clamp a plurality of the main units of the water flosser to be tested. Both clamping plates are perpendicular to the axial direction of the water flosser to be tested.

[0008] In one embodiment, the two clamping plates include a first clamping plate and a second clamping plate;

[0009] The first clamping plate has a plurality of first connecting arms and a plurality of first grooves alternately arranged on the side near the second clamping plate, and the second clamping plate has a plurality of second connecting arms and a plurality of second grooves alternately arranged on the side near the first clamping plate.

[0010] The plurality of first grooves are correspondingly opposite to the plurality of second grooves, and the first grooves and the corresponding second grooves cooperate to form a clamping position for clamping the main body of the water flosser to be tested. The plurality of first connecting arms are correspondingly connected to the plurality of second connecting arms.

[0011] In one embodiment, the first connecting arm and the opposite second connecting arm are detachably connected by a locking assembly;

[0012] The first connecting arm and the opposite second connecting arm include multiple connection positions, and the locking member is capable of locking the first connecting arm and the opposite second connecting arm in any of the connection positions;

[0013] When the first connecting arm and the opposite second connecting arm are in different connection positions, the distance between the bottom of the first groove and the bottom of the second groove is different.

[0014] In one embodiment, along the axial direction of the water flosser under test, the first connecting arm is misaligned with the opposite second connecting arm;

[0015] The first connecting arm has a plurality of first connecting holes arranged sequentially along the extension direction of the first connecting arm; the second connecting arm has a plurality of second connecting holes arranged sequentially along the extension direction of the second connecting arm.

[0016] In the first connecting arm and the opposite second connecting arm, there is at least one pair of opposite and communicating first connecting holes and second connecting holes;

[0017] The locking components are respectively locked into the same pair of opposite and connected first and second connecting holes.

[0018] In one embodiment, the test fixture further includes a first flexible pad assembly and a second flexible pad assembly;

[0019] The first flexible pad assembly is disposed on the inner wall of the first groove, and the second flexible pad assembly is disposed on the inner wall of the second groove.

[0020] In one embodiment, the chassis includes a base plate, two first side plates and two second side plates. The two first side plates are disposed on opposite sides of the base plate, and the two second side plates are connected between the two first side plates. The two second side plates divide the space between the two first side plates into a water storage cavity and the at least one storage cavity.

[0021] Each of the two first side plates has multiple slots at one end near the storage cavity. The slots on the two first side plates are opposite each other. The multiple slots at the same end of the first side plates are arranged sequentially away from the base plate. The fixing component is detachably connected to the opposite pair of slots.

[0022] In one embodiment, the test fixture further includes at least one support plate, which is installed in the at least one storage cavity in a corresponding manner;

[0023] The support plate is detachably connected to the opposite pair of slots, and the support plate is located on the side of the fixing assembly closer to the base plate.

[0024] In one embodiment, the same fixing component includes a plurality of clamping positions for clamping the main body of the water flosser to be tested, and the support plate has a plurality of through holes;

[0025] Each of the clamping positions has a projection area on the opposite support plate that covers a plurality of the vias.

[0026] In one embodiment, both the water storage chamber and the storage chamber have openings on the same side, and the test fixture also includes a protective cover and at least one guide plate.

[0027] The protective cover is provided over the opening structure of the water storage cavity and covers at least a portion of the opening structure of the storage cavity;

[0028] The guide plate is installed on the side of the protective cover near the chassis. The at least one guide plate is provided in correspondence with the at least one storage cavity.

[0029] The guide plate has several return water holes on the side near the storage cavity, and the return water holes are used to insert the nozzle of the water flosser to be tested.

[0030] In one embodiment, the end of the guide plate near the water storage cavity is rotatably connected to the protective cover via a damping shaft.

[0031] The beneficial effects of this application are as follows: This application proposes a testing fixture that can be used for aging tests of water flossers.

[0048] The embodiments of this application are described in detail below.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0049] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0050] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0051] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0052] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0053] like Figure 1 As shown, a Cartesian coordinate system is established. The length direction of the test fixture 100 is defined to be parallel to the x-axis, the width direction to be parallel to the y-axis, and the height direction to be parallel to the z-axis. It is understood that the above definitions are only for ease of understanding the relative positional relationships of the components in the test fixture 100 and should not be construed as limitations on this application.

[0054] The embodiment provides a test fixture 100 that can be used for aging tests of water flossers.

[0055] like Figures 1 to 3 As shown, the test fixture 100 may include a chassis 10 and at least one fixing component 20.

[0056] The chassis 10 may include a water storage chamber 101 and at least one storage chamber 102, with the at least one storage chamber 102 disposed around the periphery of the water storage chamber 101. The water storage chamber 101 can be used to store tap water or other water sources. The storage chamber 102 can be used to hold the oral irrigator 200 to be tested. It is understood that the oral irrigator 200 to be tested may include the oral irrigator main unit (hereinafter referred to as main unit 210) and the oral irrigator nozzle (hereinafter referred to as nozzle 220).

[0057] The chassis 10 is also provided with a water supply port 103 that communicates with the water storage chamber 101. The end of the water supply port 103 away from the water storage chamber 101 is used to connect to the main unit 210 of the oral irrigator 200 under test. During the aging test, the oral irrigator 200 under test can obtain water from the water storage chamber 101.

[0058] At least one fixing component 20 is installed in at least one storage cavity 102, meaning that one fixing component 20 can be installed in each storage cavity 102. The fixing component 20 may include two opposing clamping plates, namely a first clamping plate 21 and a second clamping plate 22. Both the first clamping plate 21 and the second clamping plate 22 are perpendicular to the axial direction of the water flosser 200 to be tested. The first clamping plate 21 and the second clamping plate 22 can cooperate to clamp a plurality of water flossers 200 to be tested. Specifically, the first clamping plate 21 and the second clamping plate 22 can clamp and fix the main unit 210 of the water flosser 200 to be tested. In some embodiments, the axial direction of the water flosser 200 to be tested may be parallel to the height direction of the testing fixture 100. Therefore, the water flosser 200 to be tested can remain upright during the aging test to simulate the user's usage state when using the water flosser, thereby improving the reliability of the test results.

[0059] During the aging test of the water flosser 200, the main unit 210 can be clamped and fixed by the fixing component 20, which can fix the water flosser 200 relative to its own storage cavity 102. This reduces the probability of the water flosser 200 shaking or tilting due to its own vibration, thereby reducing the probability of downtime during the aging test, ensuring the water flosser 200 can successfully complete the aging test, and also improving test efficiency.

[0060] like Figure 3 As shown, the chassis 10 may include a base plate 11, two first side plates 12, and two second side plates 13. The two first side plates 12 are respectively disposed on opposite sides of the base plate 11, and both first side plates 12 are perpendicular to the base plate 11. In some embodiments, the first side plates 12 may be arranged on both sides of the base plate 11 along the width direction of the test fixture 100. In embodiments, the two first side plates 12 may be fixedly connected to the base plate 11 by welding, bonding, fusion, integral molding, or other methods, and the first side plates 12 and the base plate 11 are sealed together.

[0061] The two second side plates 13 are spaced apart and parallel, and both second side plates 13 are perpendicular to the base plate 11 and the first side plate 12. The two second side plates 13 are connected between the two first side plates 12, and the side of the second side plate 13 closest to the base plate 11 is connected to the base plate 11. For example, the second side plates 13 can be fixedly connected to the base plate 11 and the first side plates 12 by welding, bonding, fusion, integral molding, etc., and the connection between the second side plate 13 and the base plate 11 and the first side plate 12 is a sealed connection.

[0062] Correspondingly, the two second side plates 13 can divide the space between the two first side plates 12 into a water storage cavity 101 and at least one storage cavity 102.

[0063] In some embodiments, along the width direction of the test fixture 100, the two second side plates 13 may be disposed near the center of the base plate 11. The two second side plates 13 can divide the space between the two first side plates 12 into a water storage cavity 101 and two storage cavities 102, which are respectively disposed on both sides of the water storage cavity 101. In some embodiments, the two storage cavities 102 are symmetrically arranged about the water storage cavity 101. The side of each storage cavity 102 away from the water storage cavity 101 is an open structure, so that the operator can insert the oral irrigator 200 to be tested into the storage cavity 102.

[0064] In other embodiments, along the width direction of the test fixture 100, two second side plates 13 may also be disposed near one end of the base plate 11, and one of the second side plates 13 is connected to one end of the base plate 11. Accordingly, the two second side plates 13 can divide the space between the two first side plates 12 into a water storage cavity 101 and a storage cavity 102, with the storage cavity 102 located on one side of the water storage cavity 101.

[0065] Combined again Figure 1 Both storage cavities 102 can hold the water flosser 200 to be tested. Correspondingly, multiple water flossers 200 to be tested can be placed in the test fixture 100 at the same time, so that multiple water flossers 200 to be tested can be subjected to aging tests simultaneously, thereby improving test efficiency.

[0066] Correspondingly, the test fixture 100 may include two sets of fixing components 20, which are installed one-to-one in the two storage cavities 102. The two fixing components 20 can clamp and fix the water flosser 200 to be tested in their respective storage cavities 102, thereby fixing the water flosser 200 relative to the chassis 10 and ensuring the smooth progress of the aging test. In this embodiment, the structure and installation method of the two sets of fixing components 20 can be set to be identical.

[0067] like Figures 2 to 4 As shown, the fixing assembly 20 includes a first clamping plate 21 and a second clamping plate 22 facing each other. In some embodiments, the first clamping plate 21 is connected between the two first side plates 12 to achieve the connection between the fixing assembly 20 and the chassis 10. The first clamping plate 21 may be disposed near the side of the storage cavity 102 away from the water storage cavity 101. The second clamping plate 22 may be connected to the first clamping plate 21, and the second clamping plate 22 is disposed near the water storage cavity 101 relative to the first clamping plate 21.

[0068] In some embodiments, the second clamping plate 22 is detachably connected to the first clamping plate 21, and both the second clamping plate 22 and the first clamping plate 21 include multiple connection positions. When the second clamping plate 22 and the first clamping plate 21 are in different connection positions, they can cooperate to clamp and fix main units 210 of different sizes. Therefore, the test fixture 100 can be used for aging tests of different models of oral irrigators 200, improving the utilization rate and versatility of the test fixture 100.

[0069] Combined again Figure 5 The first clamping plate 21 near the second clamping plate 22 may have a plurality of first grooves 211 and a plurality of first connecting arms 212 alternately arranged in sequence. The first grooves 211 may be flat U-shaped grooves facing the water storage cavity 101. The first connecting arms 212 may extend along the width direction of the test fixture 100.

[0070] Understandably, a number of first grooves 211 and a number of first connecting arms 212 are arranged alternately along the length of the test fixture 100. For example, the first clamping plate 21 may include one, two, five, six, eight or other numbers of first grooves 211, and the first clamping plate 21 may include two, three, six, seven, eight or nine or other numbers of first connecting arms 212.

[0071] Combined again Figure 6 On the side of the second clamping plate 22 closest to the first clamping plate 21, a plurality of second grooves 221 and a plurality of second connecting arms 222 are alternately arranged. Correspondingly, the second grooves 221 are also flat U-shaped grooves and are arranged on the side away from the water storage cavity 101. The second connecting arms 222 may also extend along the width direction of the test fixture 100.

[0072] In this embodiment, the number of second grooves 221 may be equal to the number of first grooves 211, and the number of second connecting arms 222 may be equal to the number of first connecting arms 212.

[0073] The first groove 211 can be disposed opposite to the second groove 221, and the first groove 211 and the second groove 221 cooperate to form a clamping position 201 for clamping the main unit 210, that is, the main unit 210 passes through the clamping position 201 and is clamped and fixed by the two clamping plates. Correspondingly, the first clamping plate 21 and the second clamping plate 22 can cooperate to form a plurality of clamping positions 201 for clamping and fixing the main unit 210.

[0074] like Figure 2 , Figures 4 to 7As shown, multiple second connecting arms 222 can be detachably connected to multiple first connecting arms 212 in a one-to-one correspondence, and the second connecting arms 222 and the corresponding first connecting arms 212 have multiple connection positions. When the second connecting arms 222 and the corresponding first connecting arms 212 are in different connection positions, the distance between the bottom of the first groove 211 and the bottom of the corresponding second groove 221 can be set to be different. Thus, the first groove 211 and the second groove 221 can cooperate to form clamping positions 201 of different sizes to accommodate main units 210 of different sizes, that is, to accommodate oral irrigators 200 to be tested of different sizes.

[0075] The test fixture 100 also includes a locking assembly 40, which can be used to lock the first connecting arm 212 and the opposing second connecting arm 222 into the desired connection position. It is understood that multiple sets of locking assemblies 40 can be provided, and at least one set of locking assemblies 40 can be connected between any pair of first connecting arms 212 and second connecting arms 222 to ensure a stable connection between the first clamping plate 21 and the second clamping plate 22, thereby providing stable and reliable clamping and fixing for the oral irrigator 200 under test. For example, one, two, or three sets of locking assemblies 40 can be connected between the same pair of first connecting arms 212 and second connecting arms 222.

[0076] like Figure 2 , Figure 4 and Figure 7 As shown, along the height direction of the test fixture 100, the first clamping plate 21 can be offset from the second clamping plate 22. For example, the first clamping plate 21 can be positioned closer to the base plate 11 relative to the second clamping plate 22. Correspondingly, the second connecting arm 222 can be located on the side of the opposite first connecting arm 212 away from the base plate 11.

[0077] In other embodiments, the second clamping plate 22 may be disposed near the base plate 11 relative to the first clamping plate 21, and correspondingly, the second connecting arm 222 may be located on the side of the opposite first connecting arm 212 near the base plate 11.

[0078] Combined again Figure 5 and Figure 6 The first connecting arm 212 has a plurality of first connecting holes 2121, which can be arranged sequentially along the extension direction of the first connecting arm 212. The second connecting arm 222 has a plurality of second connecting holes 2221, which can be arranged sequentially along the extension direction of the second connecting arm 222.

[0079] When the first connecting arm 212 and the opposite second connecting arm 222 are in any connection position, at least one pair of opposing and communicating first connecting holes 2121 and second connecting holes 2221 exist in both the first connecting arm 212 and the opposite second connecting arm 222. The locking assembly 40 can be locked onto the pair of opposing and communicating first connecting holes 2121 and second connecting holes 2221 to lock the corresponding first connecting arm 212 and second connecting arm 222.

[0080] like Figure 7 As shown, in some embodiments, the locking assembly 40 may include a matching bolt 41 and a nut 42. The bolt 41 may be sequentially inserted into a pair of opposing and communicating first connecting holes 2121 and second connecting holes 2221, and the nut 42 is locked to the end of the bolt 41 away from the bolt head to lock the corresponding first connecting arm 212 and second connecting arm 222, thereby ensuring that the first connecting arm 212 and the opposing second connecting arm 222 are in the desired connection position.

[0081] In other embodiments, the locking assembly 40 may be a bolt 41, which may be directly screwed into the opposing and communicating first connecting hole 2121 and second connecting hole 2221. Of course, in other embodiments, the locking assembly 40 may also be a structural component such as a pin, which can lock the opposing first connecting arm 212 and second connecting arm 222 into the desired connection position.

[0082] In the same fixing component 20, multiple pairs of first connecting arms 212 and second connecting arms 222 can be in the same connecting position, which can be used to clamp and fix multiple oral irrigators 200 of the same model to be tested.

[0083] In other embodiments, the first clamping plate 21 and the second clamping plate 22 may be located on the same plane parallel to the base plate 11. The locking assembly 40 may be a bolt 41 of a certain length. The bolt 41 may pass through the first connecting arm 212 along the width direction of the test fixture 100 and protrude from the side of the first connecting arm 212 closer to the second clamping plate 22. The head of the bolt 41 may be confined to the side of the first clamping plate 21 away from the second clamping plate 22. The bolt 41 may be screwed to the opposite second connecting arm 222. The size of the clamping position 201 can be adjusted by adjusting the screw length between the bolt 41 and the second connecting arm 222 to accommodate different models of the oral irrigator 200 to be tested.

[0084] like Figure 1 , Figure 2 and Figure 4As shown, the test fixture 100 also includes a first flexible pad assembly 31 and a second flexible pad assembly 32. The first flexible pad assembly 31 is disposed on the inner wall of the first groove 211, i.e., on the surface near the host 210. The second flexible pad assembly 32 is disposed on the inner wall of the second groove 221, i.e., on the surface near the host 210.

[0085] In some embodiments, the first flexible pad assembly 31 may include three flexible pads 311. One flexible pad 311 is located at the bottom of the first groove 211, that is, a section of the inner wall of the first groove 211 opposite to the second groove 221. The other two flexible pads 311 may be disposed on the inner walls on both sides of the first groove 211. The flexible pads 311 may also be made of flexible materials such as silicone, rubber, or foam.

[0086] In other embodiments, the first flexible pad assembly 31 may also include a flexible pad 311 that extends over the inner wall of the first groove 211.

[0087] The structure and arrangement of the second flexible pad assembly 32 can be the same as those of the first flexible pad assembly 31, and will not be described again here.

[0088] When the two clamping plates hold and fix the main unit 210, the first flexible pad assembly 31 and the second flexible pad assembly 32 can be respectively placed between the corresponding clamping plates and the main unit 210. On the one hand, this can prevent the two clamping plates from directly contacting the main unit 210 and causing scratches or other damage. On the other hand, the flexible pad assemblies can absorb the vibration generated by the main unit 210 during operation, thereby reducing the shaking amplitude of the main unit 210 relative to the test fixture 100 and ensuring the stability of the water flosser 200 under test during aging tests.

[0089] like Figure 2 and Figure 3 As shown, in some embodiments, the first clamping plate 21 is detachably connected between the two first side plates 12, that is, both ends of the first clamping plate 21 are detachably connected to the corresponding first side plates 12. Correspondingly, the water flosser 200 to be tested can also be easily installed on the test fixture 100.

[0090] Along the height direction of the test fixture 100, the position of the first clamping plate 21 relative to the first side plate 12 is adjustable, that is, the position of the fixing component 20 along the axial direction of the water flosser 200 to be tested is adjustable. Therefore, the fixing component 20 can be adapted to water flossers 200 with different axial dimensions, and the fixing component 20 can be positioned as close as possible to the center of gravity of the water flosser 200 to ensure that the fixing component 20 can provide a stable and reliable clamping effect for the water flosser 200 to be tested, reducing the shaking amplitude of the water flosser 200 to be tested.

[0091] In some embodiments, each of the two first side plates 12 has a plurality of slots 121 at one end near the storage cavity 102, and the slots 121 can extend along the width direction of the test fixture 100. It is understood that both ends of the first side plate 12 can have a plurality of slots 121. For example, one end of the first side plate 12 can have two, three, five, six, or other numbers of slots 121. In some embodiments, both ends of the first side plate 12 can have the same number of slots 121.

[0092] The end of slot 121 away from the water storage chamber 101 is an open structure. Multiple slots 121 located at the same end of the same first side plate 12 can be arranged at intervals along the axial direction of the water flosser 200 to be tested. In this embodiment, on both sides of the same storage chamber 102, multiple slots 121 on one first side plate 12 can be arranged opposite to slots 121 on the other first side plate 12. Accordingly, an equal number of slots 121 can be provided on both first side plates 12.

[0093] In this embodiment, the two opposing slots 121 in the two first side plates 12 can be referred to as a pair of slots 121. The two ends of the first clamping plate 21 can be connected one-to-one with the two slots 121 in the pair to realize the installation of the fixing component 20 on the chassis 10.

[0094] Combined again Figure 5 and Figure 6 Along the length of the test fixture 100, each end of the first clamping plate 21 has a plate-shaped first engagement portion 213 protruding from it. Along the width of the test fixture 100, the first engagement portion 213 is positioned away from the water storage chamber 101 relative to the first connecting arm 212. When the first clamping plate 21 is installed in the chassis 10, the two first engagement portions 213 can be inserted one-to-one into a pair of slots 121. In some embodiments, the first engagement portion 213 can be tightly fitted (i.e., transition fit) with the slot 121. During aging tests, this ensures that the first engagement portion 213 is fixed relative to the slot 121. When the fixing assembly 20 needs to be removed from the chassis 10, it also ensures that the operator can easily pull the first engagement portion 213 out of the slot 121.

[0095] In other embodiments, the first insertion part 213 and the first side plate 12 can also be detachably connected by means of screw connection, snap-fit ​​connection or other means.

[0096] Furthermore, after the two first mating parts 213 are mated into a pair of slots 121, the first connecting arms 212 near both ends of the first clamping plate 21 can abut against the side of the first side plate 12 near the storage cavity 102. Thus, the movement of the first clamping plate 21 can be further restricted in the length direction of the test fixture 100 to ensure a stable connection between the fixing assembly 20 and the chassis 10.

[0097] like Figure 3 As shown, the first side plate 12 near the storage cavity 102 may also have several wire-passing holes 122 communicating with the storage cavity 102, allowing wires (not shown) connected to the water flosser 200 under test to pass through. Understandably, the other end of the wire can be connected to a power supply (not shown). During the aging test, the power supply can continuously power the water flosser 200 under test, preventing interruption due to insufficient power and ensuring the smooth progress of the aging test.

[0098] Understandably, wire-passing holes 122 are provided at both ends of the same first side plate 12. When multiple wire-passing holes 122 are provided at the same end of the first side plate 12, the multiple wire-passing holes 122 can be alternately arranged with multiple slots 121 in sequence. In the embodiment, the wire-passing holes 122 can fix and organize the wires, avoiding the problem of wires becoming tangled and messy.

[0099] like Figure 1 , Figure 2 and Figure 8 As shown, the test fixture 100 may further include a support plate 50 for supporting the oral irrigator 200 to be tested. In embodiments, the number of support plates 50 may be equal to the number of fixing components 20, and the support plates 50 may be installed one-to-one in the storage cavity 102. In some embodiments, two support plates 50 may be provided, and the structure and installation method of the two support plates 50 may be the same.

[0100] The support plate 50 can be set on the side of the fixing component 20 near the base plate 11, and the support plate 50 is parallel to the base plate 11. When using the test fixture 100, the support plate 50 is located at the end of the main unit 210 away from the nozzle 220, and the support plate 50 provides support for the main unit 210. At the same time, the support plate 50 can also further limit the shaking of the main unit 210, ensuring the stability of the main unit 210 during the aging test, that is, ensuring the stability of the water flosser 200 under test during the aging test.

[0101] Combined again Figure 3 The support plate 50 is detachably connected between the two first side plates 12. Specifically, along the length of the testing fixture 100, two second engagement portions 51 can protrude from both ends of the support plate 50. The two second engagement portions 51 can be inserted into the paired slots 121 one by one, and the second engagement portions 51 can be tightly fitted with the corresponding slots 121. In the embodiment, the height of the support plate 50 from the base plate 11 can also be adjusted according to the axial dimension of the water flosser 200 to be tested, so that the support plate 50 can be selectively connected to a specific slot 121 to ensure that the support plate 50 can provide stable and reliable support for the water flosser 200 to be tested.

[0102] like Figure 3As shown, each of the two second side plates 13 near the bottom plate 11 can have a plurality of water inlets 103. In some embodiments, the number of water inlets 103 on the same second side plate 13 can be equal to the number of clamping positions 201 in the fixing component 20 near the second side plate 13, and the water inlets 103 can correspond one-to-one with the clamping positions 201 on the fixing component 20. It can be understood that a water inlet 103 can be used to connect to a water flosser 200 to be tested.

[0103] Combined again Figure 10 A first control valve 61 may also be installed at the water supply port 103, which can be used to control the opening and closing of the water supply port 103. In some embodiments, the first control valve 61 may be a one-way solenoid valve. When using the test fixture 100, the end of the first control valve 61 away from the water storage chamber 101 can be connected to the main unit 210 through a water pipe or other structural component. Correspondingly, the first control valve 61 can also control the amount of water supplied from the water storage chamber 101 to the oral irrigator 200 under test.

[0104] In other embodiments, the first control valve 61 may also be a manual valve.

[0105] like Figure 1 , Figure 2 and Figure 8 As shown, a through hole 52 for a water supply pipe to pass through can be provided on the support plate 50. The end of the water pipe away from the first control valve 61 can pass through the through hole 52 and communicate with the main unit 210. In some embodiments, multiple through holes 52 are provided on the support plate 50 at positions corresponding to the projection area of ​​any clamping position 201. Thus, different models of oral irrigators 200 under test can be accommodated, and a through hole 52 can be made to communicate with the water inlet in the main unit 210 as much as possible, so that the water pipe can be smoothly passed through the corresponding through hole 52 and connected to the water inlet of the main unit 210.

[0106] Understandably, both the water storage chamber 101 and the storage chamber 102 can have an open structure at the end furthest from the base plate 11. When the water flosser 200 is subjected to aging tests using the test fixture 100, the nozzle 220 can protrude relative to the opening of the storage chamber 102 and face the opening of the water storage chamber 101. Thus, the water jet from the nozzle 220 can collect in the water storage chamber 101. Correspondingly, the water flosser 200 and the water storage chamber 101 can form a water circulation loop, allowing for water recycling. During the aging test, it can also be ensured that the water storage chamber 101 can continuously supply water to the water flosser 200, preventing the test from being interrupted due to water shortage.

[0107] like Figure 1 , Figure 2 and Figure 9As shown, the test fixture further includes a cover assembly 70, which can be installed on the end of the chassis 10 away from the base plate 11. The cover assembly 70 can protect the end of the water storage chamber 101 away from the base plate 11, reducing the entry of dust and other debris into the water storage chamber 101, thereby avoiding contamination of the water source in the water storage chamber 101 and ensuring the smooth progress of the aging test.

[0108] Specifically, the enclosure assembly 70 may include a protective cover 71 and a deflector 72. The protective cover 71 includes an arched cover 711 and two side panels 712, the axis of which may be parallel to the length direction of the test fixture 100. The two side panels 712 are connected to the two ends of the arched cover 711 in a one-to-one correspondence to close the two ends of the arched cover 711. In the embodiment, the two side panels 712 may be connected to the arched cover 711 by welding, integral molding, or other methods.

[0109] The protective cover 71 can be fixedly installed on the end of the chassis 10 away from the bottom plate 11. For example, the ends of the two side plates 712 away from the arched cover 711 can be fixedly connected to the sides of the two first side plates 12 away from the bottom plate 11 by welding, bonding, fusion, etc. In the embodiment, the protective cover 71 can cover the end of the water storage cavity 101 away from the bottom plate 11 to reduce the entry of dust and other debris into the water storage cavity 101. In addition, the two sides of the protective cover 71 can extend to the top of the corresponding storage cavity 102 to cover part of the storage cavity 102. Specifically, the protective cover 71 can extend to the top of the clamping position 201. When using the test fixture 100, the nozzle 220 of the water flosser 200 to be tested can be inserted into the protective cover 71 and face the side of the water storage cavity 101.

[0110] In other embodiments, the protective cover 71 may completely cover the opening structure of the storage cavity 102 on the side away from the base plate 11.

[0111] Combined again Figure 12 In some embodiments, the arched cover 711 may have a notch 7111 parallel to the second side plate 13 on the side near the storage cavity 102. When the water flosser 200 to be tested is installed on the test fixture 100, the nozzle 220 can also be easily inserted into the arched cover 711.

[0112] like Figures 9 to 12 As shown, the cover assembly 70 may include a plurality of guide plates 72. Specifically, the number of guide plates 72 may be equal to the number of storage cavities 102. In some embodiments, two guide plates 72 may be provided, with the two guide plates 72 correspondingly installed on both sides of the protective cover 71 near the two storage cavities 102, and the two guide plates 72 may be symmetrically arranged. In the embodiments, the structure and installation method of the two guide plates 72 may be the same.

[0113] In this embodiment, the deflector 72 is generally flat and is inclined relative to the second side plate 13. Additionally, the deflector 72 can extend from one side plate 712 to another side plate 712.

[0114] The guide plate 72 may include a first side 721 and a second side 722. The first side 721 is disposed on the side closer to the water storage cavity 101. Specifically, a section of the guide plate 72 near the first side 721 can be inserted into the water storage cavity 101, that is, a section of the guide plate 72 near the first side 721 can be located on the side of the second side plate 13 near the water storage cavity 101.

[0115] The end of the guide plate 72 near the second side 722 may protrude relative to the end of the water storage cavity 101 near the protective cover 71. Simultaneously, the guide plate 72 may gradually tilt from the first side 721 to the second side 722 towards the storage cavity 102. Alternatively, it can be understood that the guide plate 72 extends from the water storage cavity 101 to the corresponding storage cavity 102, and gradually tilts away from the chassis 10.

[0116] like Figures 10 to 13 As shown, the guide plate 72 may have a plurality of return water inlets 7201 at one end near the second side 722. The number of return water inlets 7201 may be equal to the number of clamping positions 201 in the same group of fixing components 20, and the return water inlets 7201 may correspond one-to-one with the clamping positions 201 on the opposite side. In some embodiments, the side of the return water inlet 7201 away from the first side 721 may be an open structure, that is, the return water inlet 7201 is a U-shaped slotted structure.

[0117] When conducting aging tests on the water flosser 200 using the test fixture 100, the end of the nozzle 220 furthest from the main unit 210 can be inserted into the corresponding return water port 7201. The guide plate 72 acts as a shield between the nozzle 220 and the storage chamber 102. When the nozzle 220 sprays water, the shorter-range water stream falls onto the guide plate 72 under gravity and flows along the guide plate 72 towards the water storage chamber 101. This prevents the water sprayed from the nozzle 220 from entering the storage chamber 102 and causing waste, ensuring the recycling of water.

[0118] like Figure 1 , Figure 11 and Figure 13 As shown, the test fixture 100 may also include a seal 81. A seal 81 may be provided at any return port 7201. The seal 81 can be used to seal the assembly gap between the nozzle 220 and the inner wall of the return port 7201 to prevent water from overflowing from the return port 7201 into the storage cavity 102.

[0119] In some embodiments, the seal 81 may be a U-shaped sealing ring, meaning that the side of the seal 81 away from the first side 721 is an open structure. This allows the nozzle 220 to be easily inserted into the return port 7201. When the nozzle 220 is inserted into the return port 7201, the side of the seal 81 away from the inner wall of the return port 7201 can be tightly pressed against the surface of the nozzle 220. In some embodiments, the seal 81 may be made of flexible materials such as silicone or rubber.

[0120] Understandably, the seal 81 can also provide corresponding fixing and buffering for the nozzle 220, which can ensure that the nozzle 220 remains fixed relative to the return port 7201, reduce the vibration amplitude of the nozzle 220 relative to the guide plate 72, and also avoid leakage caused by assembly gaps.

[0121] In the existing technology, the nozzle 220 is removed, and the water outlet of the main unit 210 is connected back to the water storage chamber 101 via a water pipe. On the one hand, it is necessary to disassemble and assemble the nozzle 220 and install the water pipe, making the operation steps cumbersome and affecting the testing efficiency. On the other hand, because the water pipe is soft and not very stable, it is susceptible to separation from the water storage chamber 101 due to the vibration of the main unit 210, causing water leakage.

[0122] In this embodiment, a guide plate 72 is used to receive part of the water flow ejected from the nozzle 220. On one hand, this avoids the cumbersome operation of disassembling and assembling the nozzle 220 and installing the water pipe, simplifying the operation steps and improving testing efficiency. On the other hand, the nozzle 220 is generally made of rigid materials, which have higher stability compared to flexible water pipes. Simultaneously, the nozzle 220 can be further secured by the sealing member 81, effectively preventing the nozzle 220 from detaching from the return port 7201 and avoiding leakage.

[0123] like Figure 9 and Figure 10 As shown, further, the section of the guide plate 72 near the first side 721 can be an arc-shaped plate, and the center of the arc-shaped plate can be located on the side of the guide plate 72 near the corresponding side storage cavity 102. That is, the section of the guide plate 72 inserted into the water storage cavity 101 is an arc-shaped plate. Thus, the assembly gap between the guide plate 72 and the corresponding second side plate 13 can be covered and protected to prevent water from splashing and overflowing. At the same time, it can also further guide the water flow on the guide plate 72 towards the water storage cavity 101, reducing the probability of water splashing to the opposite side.

[0124] like Figure 9 , Figure 10 and Figure 13As shown, the guide plate 72 is further rotatably mounted on the two side plates 712, that is, the guide plate 72 is rotatably mounted relative to the protective cover 71. Specifically, the end of the guide plate 72 near the first side 721 is rotatably connected to the two side plates 712. When the guide plate 72 rotates relative to the protective cover 71, the distance between the return port 7201 and the fixed assembly 20 can be adjusted. Thus, the height of the return port 7201 can be adjusted according to the axial dimension of the water flosser 200 under test, so that the height of the return port 7201 is adapted to the height of the nozzle 220.

[0125] In some embodiments, the deflector 72 can be rotatably connected to the surrounding plate 712 via a damping pivot 73. This allows the deflector 72 to remain in any adjusted position, preventing it from rotating arbitrarily.

[0126] In this embodiment, the protective cover 71 further includes a partition 713, which may be located on the side of the arched cover 711 near the water storage chamber 101. In some embodiments, the partition 713 may be parallel to the second side plate 13. The partition 713 may be located between the two guide plates 72, and the end of the partition 713 away from the arched cover 711 may extend to the opening structure of the water storage chamber 101. When the water flosser 200 to be tested is subjected to aging tests, the partition 713 can block the nozzles 220 on both sides, preventing water with a longer range from splashing to the return water port 7201 on the opposite side and the gap between the guide plate 72 and the arched cover 711, thereby avoiding water leakage into the storage chamber 102 and causing waste.

[0127] like Figure 13 As shown, the chassis 10 also has a drain port 104 communicating with the water storage chamber 101. When the test fixture 100 is not in use, needs to have its water source replaced, or needs to be cleaned, the water in the water storage chamber 101 can be drained through the drain port 104. In some embodiments, the drain port 104 can be provided on a first side plate 12 and located at one end of the first side plate 12 near the bottom plate 11, so as to drain the water in the water storage chamber 101. In embodiments, the drain port 104 can be connected to a second control valve 62 through a structure such as a water pipe, which can be used to control the opening and closing of the drain port 104. In some embodiments, the second control valve 62 can be a one-way solenoid valve.

[0128] Of course, in other embodiments, the second control valve 62 may also be a manual valve.

[0129] Understandably, the test fixture 100 may also include a controller (not shown), which can be electrically connected to the electrical components in the test fixture 100. Simultaneously, during the aging test of the water flossers 200 to be tested, the controller can also be electrically connected to each water flosser 200 to be tested mounted on the test fixture 100. Thus, the controller can control the operation of each electrical component in the test fixture 100 and each water flosser 200 to be tested, thereby facilitating the successful aging test.

[0130] like Figure 13 As shown, in some embodiments, an anti-slip pad 82 can be fixedly provided on the side of the base plate 11 away from the water storage cavity 101. When the test fixture 100 is placed on a workbench, the ground or other position, the anti-slip pad 82 can prevent the test fixture 100 from moving randomly relative to the workbench or the ground, ensuring the stability of the test fixture 100 and ensuring the smooth progress of the aging test.
