Description

Technical Field

[0001] The present application relates to the field of oral care technology, and in particular to a fluid connector, an oral care device, and an access pipe. Background Art

[0002] In related technologies, the integrated flushing machine is detachably connected to an external water source through a fluid connector, aiming to enhance flexibility of use, allowing the device to perform an integrated flushing function when connected to an external water source, or to be used separately in a separated state.

[0003] However, when the flushing machine is connected to an external water source through a fluid connector, it sometimes fails to maintain a continuous water output state, and the water output stability is low, which affects the user experience. Utility Model Content

[0004] The purpose of this application is to provide a fluid connector, an oral care device, and an access pipe, which can ensure the water output stability of the oral care device and improve the user experience.

[0005] To achieve the above-mentioned objectives, the present application provides a fluid connector on one hand, which includes at least a tube group, a seal and a switch, wherein the tube group has an inlet end, an outlet end and a fluid channel connecting the inlet end and the outlet end, and the inner wall of the fluid channel is provided with a guide groove; the seal is annular, and the seal is arranged in the fluid channel and is arranged adjacent to the outlet end; the switch is slidably arranged in the fluid channel through a mating surface, and has a first position that contacts the seal to close the outlet end and a second position that makes the outlet end conductive; along the fluid flow direction in the fluid channel, one end of the guide groove extends to the seal, and the other end of the guide groove extends to upstream of the mating surface when the switch is in the second position.

[0006] To achieve the above-mentioned purpose, the present application also provides an oral care device on the other hand, which includes at least a base station unit, an oral cleaner and the above-mentioned fluid connector, wherein the base station unit is connected to the fluid connector through a delivery pipeline and is connected to the inlet end; the oral cleaner is detachably connected to the fluid connector, and after the oral cleaner is connected to the fluid connector, the base station unit can deliver liquid to the oral cleaner through the delivery pipeline and the fluid connector, so that the liquid is sprayed out through the cleaning head of the oral cleaner.

[0007] To achieve the above objectives, the present application also provides a nursing base station on the other hand, which includes at least a base station unit and the above-mentioned fluid connector, and the base station unit is connected to the fluid connector through a delivery pipeline and communicates with the inlet end.

[0008] To achieve the above-mentioned purpose, the present application also provides an access pipe fitting on the other hand, which has a first pipe section and a second pipe section that are connected to each other, wherein the axis of the first pipe section intersects with the axis of the second pipe section, and the first pipe section is provided with an inlet end at one end away from the second pipe section; the second pipe section has a first end face away from the first pipe section, and the inner wall surface of the second pipe section is provided with a guide groove, one end of the guide groove extends to the first end face, and the other end of the guide groove extends to the first pipe section.

[0009] It can be seen that the technical solution provided by the present application is to provide a guide groove on the inner wall surface of the fluid channel, and along the direction of fluid flow in the fluid channel, one end of the guide groove extends to the sealing member, and the other end of the guide groove extends to the upstream of the mating surface when it is in the second position. In this way, when the switch is in the second position, the fluid entering the fluid channel from the inlet end can flow to the outlet end through the guide groove on the side of the guide channel, without being restricted by the gap between the mating surface and the inner wall surface of the fluid channel, thereby ensuring the continuity and stability of the liquid flowing through the fluid connector.

[0010] In particular, when the fluid connector is used in an oral care device, the water intake portion of the oral cleaner of the oral care device only needs to drive the on-off member and the seal a short distance to allow liquid entering from the inlet end to flow stably through the guide groove to the water intake portion and into the oral cleaner, ensuring the continuity of water output from the oral cleaner. Accordingly, the water intake portion of the oral cleaner does not need to be made too long, thereby eliminating the need to increase the overall size of the oral cleaner. This can simultaneously meet the requirements of miniaturization and water continuity of the oral cleaner, thereby improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] An all-in-one oral care device combines both water flushing and brushing functions, providing users with a more comprehensive oral health experience. Commonly used all-in-one oral care devices are available with either built-in or external water sources. External water sources utilize the higher water pressure and volume of an external water source, providing a more powerful cleaning experience than built-in water sources.

[0029] In related technologies, flushing machines that connect to an external water source are connected to the external water source via a detachable fluid connector. This allows for use in both a connected and detached state, increasing flexibility. However, while the flushing machine is connected to the external water source via the fluid connector, the flushing machine often fails to continuously discharge water, which undoubtedly affects the user experience.

[0030] In order to explore the problem of discontinuous water discharge from the flushing machine, the applicant found through research that when the flushing machine is connected to the fluid connector, the flushing machine pushes the valve core in the fluid connector downward through the water intake portion thereon, so that the liquid from the water source can flow into the interior of the flushing machine through the fluid connector and the water intake portion, and then spray out to perform the flushing operation. However, in the related art, the flow channel for the valve core to slide up and down in the fluid connector includes at least a first flow channel section and a second flow channel section, and the second flow channel section is located between the first flow channel section and the sealing member, and by reducing the cross-sectional area of the second flow channel section, the valve core is aligned with the sealing member under the limiting action of the second flow channel section to achieve sealing. However, in this way, when the flushing machine presses the valve core in the fluid connector through the water intake portion, the water intake portion must push the valve core to the bottom of the intersection of the second flow channel section and the first flow channel section in order to allow the liquid to flow into the flushing machine stably and continuously. If the valve core is still located in the second flow channel section, the valve core will hinder the flow of liquid, and the liquid can only flow into the flushing machine through the small gap between the valve core and the inner wall of the second flow channel section. This will cause the flow rate to decrease and cannot meet the needs of normal operation of the equipment, thereby causing the flushing machine to have discontinuous water output.

[0031] The inventors of this application have attempted to achieve a stable water flow by making the water intake portion longer, so as to push the valve core to the lower part of the junction of the second flow channel section and the first flow channel section. However, due to the overall size limitation of the flushing machine, the water intake portion cannot be made too long. Moreover, due to manufacturing tolerances, there are more or less differences in the length of the water intake portion and the dimensions of the outer wall of the flushing machine and the fluid connector. This results in some water intake portions being unable to push the valve core to the space below the junction of the second flow channel section and the first flow channel section, resulting in discontinuous water flow and affecting the user experience.

[0032] Based on this, the inventor of the present application thought of setting a guide groove on the inner wall surface of the flow channel that restricts the sliding of the valve core, and making one end of the guide groove extend to the seal, and the other end of the guide groove extends to the upstream of the valve core when it is in the second position. In this way, when the water intake part drives the valve core to disengage from the seal, the liquid from the water source can flow stably to the water intake part through the guide groove, and then flow to the flushing machine through the water intake part, thereby ensuring the continuity of water output from the flushing machine and improving the user experience.

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0034] The present application provides a fluid connector 1000, which is a component used to connect and control fluid transfer. It can be used in oral care equipment, and can also be used in other equipment that needs to be interconnected and control fluid flow and disconnection. The present application does not make specific limitations on this.

[0035] Taking the fluid connector 1000 as an example of an oral care device, one end of the fluid connector 1000 is connected to the base unit 2000 via a delivery line 4000, and the other end of the fluid connector 1000 is detachably connected to the oral cleaner 3000. After the oral cleaner 3000 is connected to the fluid connector 1000, the base unit 2000 can deliver liquid to the oral cleaner 3000 through the delivery line 4000 and the fluid connector 1000, so that the liquid is sprayed through the cleaning head of the oral cleaner 3000. When the oral cleaner 3000 is separated from the fluid connector 1000, the other end of the fluid connector 1000 automatically closes to prevent the liquid from continuing to flow out.

[0036] In actual use, after the oral cleaner 3000 is connected to the fluid connector 1000, the base unit 2000 can immediately deliver fluid to the oral cleaner 3000. Of course, to facilitate user operation, the base unit 2000 and / or the oral cleaner 3000 can be provided with different cleaning modes, such as a flushing mode and a brushing mode. After the oral cleaner 3000 is connected to the fluid connector 1000, the base unit 2000 can determine whether to deliver liquid to the oral cleaner 3000 based on the different modes selected by the user. When the user selects the flushing mode, the base unit 2000 delivers liquid to the oral cleaner 3000 through the delivery pipe 4000 and the fluid connector 1000, so that the liquid is sprayed out through the cleaning head of the oral cleaner 3000. When the user selects the brushing mode, the base unit 2000 does not deliver liquid to the oral cleaner 3000.

[0037] Please also see Figures 1 to 3 As shown, in one practicable embodiment, a fluid connector 1000 includes at least a tube assembly 100. The tube assembly 100 serves as the main component of the fluid connector 1000 and is used to provide a channel for fluid flow and to support and protect other components of the fluid connector 1000. The tube assembly 100 has an inlet end 101 for receiving fluid, an outlet end 102 for discharging fluid, and a fluid channel 103 connecting the inlet end 101 and the outlet end 102. Fluid entering the fluid channel 103 from the inlet end 101 can flow to the outlet end 102 under the guidance of the fluid channel 103, thereby flowing out of the fluid connector 1000.

[0038] It should be noted that the fluid transported by the fluid connector 1000 can be gas and / or liquid, which is not specifically limited here.

[0039] The fluid connector 1000 further includes a sealing member 200 and a switch member 300. The sealing member 200 is annular and is disposed in the fluid channel 103 and adjacent to the outlet end 102. The switch member 300 serves as a valve core and has a mating surface 310. The mating surface 310 is the surface where the switch member 300 contacts the fluid channel 103. The switch member 300 is slidably disposed in the fluid channel 103 via the mating surface 310. The switch member 300 has a first position (e.g., a position where the switch member 300 contacts the sealing member 200 to close the outlet end 102) in which the switch member 300 contacts the sealing member 200. Figure 1 The position of the switch 300 shown in FIG. 1 ), and the second position of the outlet end 102 being conductive (as shown in FIG. Figure 2 That is, the opening and closing of the outlet port 102 can be controlled by whether the on-off member 300 is in contact with the sealing member 200.

[0040] The inner wall surface of the fluid channel 103 is provided with a guide groove 104, and the guide groove 104 is connected to the fluid channel 103. Along the flow direction of the fluid in the fluid channel 103, one end of the guide groove 104 extends to the seal 200, and the other end of the guide groove 104 extends to the upstream of the mating surface 310 when it is in the second position. In this way, when the switch 300 is in the second position, the fluid entering the fluid channel 103 from the inlet end 101 can flow to the outlet end 102 through the guide groove 104 on the side of the fluid channel 103, without being affected by the gap between the mating surface 310 and the inner wall surface of the fluid channel 103, thereby ensuring the continuity and stability of the liquid flowing through the fluid connector 1000. Among them, the direction of the flow of the fluid in the fluid connector 1000 can be seen in detail as follows Figure 2 Direction of arrow shown.

[0041] In particular, when the fluid connector 1000 is used in an oral care device, the water intake portion of the oral cleaner 3000 of the oral care device only needs to drive the on-off member 300 to separate a short distance from the sealing member 200. This eliminates the need to make the water intake portion of the oral cleaner 3000 excessively long, thereby eliminating the need to increase the overall size of the oral cleaner 3000. Liquid entering from the inlet end 101 can flow stably through the guide groove 104 to the water intake portion and into the oral cleaner 3000, ensuring the continuity of water output from the oral cleaner 3000. This allows the oral cleaner 3000 to meet both the requirements of miniaturization and water continuity, thereby improving the user experience.

[0042] In one practicable embodiment, the fluid connector 1000 may further include a reset member 600, which is connected to the switch member 300 and is used to provide a reset force for the switch member 300 to slide from the second position to the first position. In other words, when the force applied to the switch member 300 that causes it to slide from the first position to the second position disappears, the reset member 600 can drive the switch member 300 to slide from the second position to the first position, automatically closing the outlet end 102 and preventing fluid from flowing out. The force can be the insertion force of the water intake portion of the oral cleaner 3000, or other forces.

[0043] In practical applications, the reset member 600 can be an elastic member similar to a spring. When the switch member 300 is in the first position in contact with the sealing member 200, the reset member 600 can be in an initial state, which can be a natural state or a compressed state. When the switch member 300 slides from the first position to the second position, the switch member 300 squeezes and compresses the reset member 600. The reset member 600 is compressed to store energy and has a tendency to restore to the initial state. When the force applied to the switch member 300 disappears, the reset member 600 releases the stored energy and drives the switch member 300 to slide from the second position to the first position, thereby restoring to the initial state. Of course, the reset member 600 can also use magnetic mutual attraction or mutual repulsion to provide the switch member 300 with a reset force to slide from the second position to the first position, and this application does not make specific restrictions on this.

[0044] In another optional embodiment, the switching between the first position and the second position of the switch 300 can be driven manually or electrically by the user.

[0045] The above-mentioned guide groove 104 may have only one. Figure 3As shown, the above-mentioned guide groove 104 can also have multiple guide grooves 104, and the multiple guide grooves 104 are at least partially spaced apart along the axis of the fluid channel 103. In this way, when the switch 300 is in the second position, the fluid entering the fluid channel 103 from the inlet end 101 can flow to the outlet end 102 through the multiple guide grooves 104, thereby increasing the fluid flux of the fluid connector 1000, and then increasing the water output of the oral cleaner 3000 connected to the fluid connector 1000, thereby improving the cleaning effect of the oral cleaner 3000.

[0046] In practical applications, the number of guide grooves 104 can be two, three, four, five, six, seven, or eight. For example, eight guide grooves 104 are provided, and the eight guide grooves 104 are arranged in a circular array along the axis of the fluid channel 103. When there are multiple guide grooves 104, water can continue to flow even if a single guide groove 104 is blocked.

[0047] Regarding the specific structure of the fluid channel 103, in one feasible embodiment, the fluid channel 103 may be arranged linearly. In other words, the axis of the fluid channel 103 is a straight line, and the fluid flowing in the fluid channel 103 flows along a linear flow path.

[0048] In another optional embodiment, the fluid channel 103 may also be nonlinearly configured, and the fluid flowing in the fluid channel 103 flows along a non-linear flow path. For example, please refer again to Figure 1 As shown, the fluid channel 103 includes a first channel 1031 and a second channel 1032, wherein one end of the first channel 1031 is connected to the inlet end 101, and the other end of the first channel 1031 is connected to the outlet end 102 through the second channel 1032. The axis of the first channel 1031 intersects the axis of the second channel 1032, and the sealing member 200, the switching member 300, and the reset member 600 are disposed within the second channel 1032. In this way, the corner between the first channel 1031 and the second channel 1032 can buffer the fluid entering from the inlet end 101, preventing the fluid from directly impacting the sealing member 200 and the switching member 300, which could cause the switching member 300 to accidentally reset and / or the sealing member 200 to fail under stress, thereby ensuring the operational stability of the fluid connector 1000. At the same time, the intersection of the axis of the first channel 1031 and the axis of the second channel 1032 can also change the opening direction of the inlet end 101 and the outlet end 102, so that the opening directions of the two are not located on the same straight line, thereby adapting to the needs of different usage scenarios. In addition, the reset member 600 can be constrained between the bottom of the second channel 1032 and the switch member 300, eliminating the need for an additional limit structure on the side of the reset member 600 away from the switch member 300, thereby simplifying the structure.

[0049] Optionally, the axis of the first channel 1031 is perpendicular to the axis of the second channel 1032 .

[0050] For the specific structure of the tube group 100, please refer to Figure 1 and Figure 4 As shown, in one achievable embodiment, the pipe assembly 100 may include an inlet pipe fitting 110 and an outlet pipe fitting 120, wherein the inlet pipe fitting 110 includes a first pipe segment 111 and a second pipe segment 112 arranged at an angle. The inlet end 101 is formed at the end of the first pipe segment 111 away from the second pipe segment 112, and a first channel 1031 is formed in the first pipe segment 111 and extends along the axis of the first pipe segment 111. One end of the outlet pipe fitting 120 is sleeved onto the end of the second pipe segment 112 away from the first pipe segment 111, and the outlet end 102 is formed at the other end of the outlet pipe fitting 120. The outlet pipe fitting 120 and the second pipe segment 112 together form the second channel 1032. The on-off member 300 and the reset member 600 are disposed in the second pipe segment 112.

[0051] It is worth mentioning that, in the present application, by providing a guide groove 104 on the inner wall surface of the fluid channel 103 and cooperating with the tube group 100 formed by interconnecting the access tube 110 and the outlet tube 120, the on-off piece 300 and the reset piece 600 can be installed in the second channel 1032 through the end of the access tube 110 away from the inlet end 101, thereby eliminating the need to provide additional mounting holes on the access tube 110 for mounting the on-off piece 300 and the reset piece 600, thereby simplifying the installation method, reducing production costs, and effectively improving the sealing performance of the fluid connector 1000.

[0052] In practical applications, the first pipe section 111 and the second pipe section 112 can be integrally formed. One end of the outlet pipe fitting 120 and the end of the second pipe section 112 away from the first pipe section 111 can be connected together by a fixed method such as gluing, ultrasonic welding, or hot melting. Of course, one end of the outlet pipe fitting 120 and the end of the second pipe section 112 away from the first pipe section 111 can also be connected together by a detachable method such as a clip connection, an interference fit, or a threaded connection.

[0053] In one feasible embodiment, the incoming pipe 110 has a first end surface 113 adjacent to the outgoing pipe 120. The outgoing pipe 120 has an inner stepped surface 121 facing the first end surface 113, with the seal 200 disposed between the inner stepped surface 121 and the first end surface 113. During installation, the seal 200 can be placed within the outgoing pipe 120 or on the first end surface 113. When the outgoing pipe 120 is sleeved onto the second pipe section 112, the seal 200 is simultaneously secured in place, eliminating the need for a separate securing mechanism and simplifying installation.

[0054] like Figure 3As shown, in one feasible embodiment, the guide groove 104 is located in the second pipe segment 112, one end of the guide groove 104 extends to the first end face 113, and the other end of the guide groove 104 extends to the first pipe segment 111. In other words, the guide groove 104 is located in the same pipe segment, and the guide groove 104 extends to the first end face 113 of the access pipe 110. In this way, when machining is used, the guide groove 104 can be machined through the first end face 113, and when injection molding is used, the mold can be demolded through the first end face 113. In short, the structural design of the guide groove 104 can facilitate the production operation of the guide groove 104 and simplify the production process.

[0055] In one feasible embodiment, the fluid connector 1000 further includes a magnetic member 400, which is mounted on the outlet tube 120. The magnetic member 400 serves as a detection element. When the fluid connector 1000 is used in an oral care device, a Hall effect sensor is mounted on the oral cleaner 3000 to detect the magnetic field of the magnetic member 400, thereby determining whether the fluid connector 1000 is connected and, in turn, controlling whether the flushing mode can be activated.

[0056] In this embodiment, the magnetic member 400 can be embedded in the outlet pipe 120. For example, a receiving groove 122 can be provided on the inner step surface 121. The magnetic member 400 is installed in the receiving groove 122 and fixed therein by means of glue potting, interference fit, snap fastening, etc. In actual application, the receiving groove 122 can be an annular groove, arranged around the central hole of the inner step surface 121. Accordingly, the magnetic member 400 has an annular structure.

[0057] In one feasible embodiment, the fluid connector 1000 may further include a gland 500 having a rigid characteristic. The gland 500 is disposed between the seal 200 and the inner step surface 121, thereby further securing the magnetic member 400 through the gland 500. Of course, the magnetic member 400 may also be secured within the receiving groove 122 solely through the gland 500 to simplify the assembly process, and this application does not specifically limit this. The rigid characteristic defined in this application refers to the property of having a low ability to deform under external force.

[0058] like Figure 2 As shown, in one feasible embodiment, a first limiting portion 510 can be provided on a side of the gland 500 adjacent to the seal 200, and a second limiting portion 210 can be provided on a side of the seal 200 adjacent to the gland 500. The first limiting portion 510 and the second limiting portion 210 are mated in a concave-convex manner. In this way, the gland 500 can also limit the position of the seal 200. During installation, the seal 200 can be installed into the outlet pipe 120 with reference to the mating position of the gland 500, ensuring that the seal 200 is accurately placed in the predetermined position and ensuring a good sealing effect.

[0059] Furthermore, the first limiting portion 510 is an annular protrusion, and the second limiting portion 210 is an annular groove, that is, the pressure cover 500 is partially embedded in the seal 200. In this way, the pressure cover 500 can also provide support for the seal 200 and fix the shape of the seal 200, thereby preventing the seal 200 from deformation and failure, and improving the service life of the seal 200.

[0060] Regarding the specific structure of the switching element 300 , this application provides two achievable embodiments for reference.

[0061] Example 1: Figure 5 As shown, the switch member 300 has a sliding portion 320. The cross-section of the sliding portion 320 matches the cross-section of the fluid channel 103, so that the switch member 300 can be slidably disposed within the fluid channel 103 via the sliding portion 320. Accordingly, the outer peripheral surface of the sliding portion 320 serves as the aforementioned mating surface 310. When the switch member 300 is in the first position, the surface of the sliding portion 320 adjacent to the outlet end 102 contacts the sealing member 200, thereby closing the outlet end 102.

[0062] In actual application, the cross-section of the sliding portion 320 can be circular. In the natural state, the through hole of the seal 200 is a truncated cone and gradually shrinks toward the sliding portion 320. The diameter of the sliding portion 320 is larger than the minimum diameter of the through hole of the seal 200, so that the sliding portion 320 cannot pass through the seal 200 and contact the side of the seal 200 adjacent to the sliding portion 320, thereby closing the outlet end 102.

[0063] Example 2: Figure 1 and Figure 6As shown, based on the first embodiment, the switch member 300 may further include a plug-in portion 330. The plug-in portion 330 is disposed on a surface of the sliding portion 320 adjacent to the outlet end 102. A sealing surface 340 is provided between the plug-in portion 330 and the mating surface 310. The plug-in portion 330 is truncated conical and gradually narrows in size as it moves away from the sliding portion 320. When the switch member 300 is in the first position, the plug-in portion 330 is inserted into the through-hole of the sealing member 200, and the sealing surface 340 contacts the sealing member 200, thereby closing the outlet end 102. In this way, the on-off member 300 is equivalent to adding a portion extending toward the outlet end 102, shortening the distance between the on-off member 300 and the outlet end 102. Accordingly, the water intake portion of the oral cleaner 3000 can push the sliding portion 320 further away from the sealing member 200, increasing the length of the guide groove 104 downstream of the sliding portion 320 when in the second position, so that the liquid flowing through the fluid connector 1000 can flow more continuously and stably into the oral cleaner 3000. Alternatively, the water intake portion of the oral cleaner 3000 can also be made shorter, thereby further reducing the size of the oral cleaner 3000 and achieving a miniaturized design.

[0064] In practice, the minimum diameter of the insertion portion 330 should be smaller than the minimum diameter of the through-hole of the sealing element 200 in its natural state, so that when the on-off member 300 is in the first position, the insertion portion 330 is inserted into the through-hole of the sealing element 200. The cooperation between the insertion portion 330, the sealing surface 340, and the sealing element 200 further enhances the sealing performance of the fluid connector 1000, preventing water leakage when the fluid connector 1000 is separated from the oral cleaner 3000. If the fluid connector 1000 is accidentally separated from the oral cleaner 3000 and the water pump in the base unit 2000 is still operating, the fluid connector 1000 will still be sealed and leak-proof even when subjected to high-pressure water.

[0065] When the reset member 600 adopts an annular structure (such as a spring or an elastic sleeve, etc.), the switch member 300 in the above-mentioned embodiment 1 and embodiment 2 may further have a guide portion 350, and one end of the reset member 600 is sleeved on the guide portion 350. In this way, when the reset member 600 follows the sliding compression and expansion of the switch member 300, the guide portion 350 ensures that the reset member 600 maintains the correct deformation direction during the compression and expansion process, thereby avoiding functional failure due to misalignment.

[0066] Based on the same inventive concept, Figure 7As shown, the present application also provides an oral care device that integrates the above-mentioned fluid connector 1000. The oral care device at least includes a base unit 2000 for liquid supply, an oral cleaner 3000 for oral cleaning, and the above-mentioned fluid connector 1000, wherein the base unit 2000 is connected to the fluid connector 1000 through a delivery pipeline 4000 and is in communication with the inlet port 101. The oral cleaner 3000 is detachably connected to the fluid connector 1000. When the oral cleaner 3000 is connected to the fluid connector 1000, the base unit 2000 can deliver liquid to the oral cleaner 3000 through the delivery pipeline 4000 and the fluid connector 1000, so that the liquid is sprayed out through the cleaning head of the oral cleaner 3000. The oral cleaner 3000 is a kind of all-in-one irrigator and a water flosser.

[0067] It should be pointed out that, regarding the specific structure of the fluid connector 1000, reference may be made to the detailed description in the above embodiment, which will not be repeated here.

[0068] In actual application, the base unit 2000 has a water tank and a pump body, and the delivery pipeline 4000 is connected to the water tank through the pump body, so that the pump body draws liquid from the water tank and delivers it to the delivery pipeline 4000. The access pipe 110 can be formed with a connector at the inlet end 101 to facilitate the connection between the delivery pipeline 4000 and the fluid connector 1000.

[0069] like Figure 8 As shown, a limiting groove 123 is provided on the outer wall surface of the outlet tube 120. Correspondingly, a buckle 3100 is provided on the handle of the oral cleaner 3000. The oral cleaner 3000 is detachably connected to the fluid connector 1000 by means of the mutual engagement of the buckle 3100 and the limiting groove 123.

[0070] The handle of the oral cleaner 3000 is also provided with a water intake portion 3200. The water intake portion 3200 is a hollow tubular structure, and the free end of the water intake portion 3200 is provided with a water intake port 3210 that penetrates the inner and outer walls of the water intake portion 3200. When the oral cleaner 3000 is connected to the fluid connector 1000, the water intake portion 3200 can sequentially pass through the outlet end 102 and the sealing member 200 to abut against the switch member 300, and apply downward pressure to the switch member 300 to separate the switch member 300 from the sealing member 200. The water intake port 3210 is located between the sealing member 200 and the switch member 300 and is connected to the guide groove 104. Therefore, the liquid provided by the base unit 2000 can flow to the oral cleaner 300 through the delivery pipeline 4000 and the fluid connector 1000.

[0071] Based on the same inventive concept, the present application also provides a nursing base station integrated with the above-mentioned fluid connector 1000. The nursing base station can be used as a separate component in conjunction with the oral cleaner 3000 to provide liquid for rinsing the oral cleaner 3000. Specifically, the nursing base station includes at least a base unit 2000 and the above-mentioned fluid connector 1000. The base unit 2000 is connected to the fluid connector 1000 via a delivery pipeline 4000 and is in communication with the inlet port 101.

[0072] It should be noted that the specific structure of the fluid connector 1000 can be referred to the detailed description in the above embodiment, which will not be repeated here. The care base station can also be integrated with a charging module to charge the oral cleaner 3000.

[0073] Based on the same inventive concept, the present application also provides an access fitting 110, which can be integrally installed into or removed from the fluid connector 1000. Specifically, the access fitting 110 comprises a first pipe segment 111 and a second pipe segment 112, which are interconnected. The axis of the first pipe segment 111 intersects the axis of the second pipe segment 112, and an inlet end 101 is provided at one end of the first pipe segment 111 distal from the second pipe segment 112. The second pipe segment 112 has a first end face 113 distal from the first pipe segment 111. A guide groove 104 is provided on the inner wall of the second pipe segment 112, with one end of the guide groove 104 extending to the first end face 113 and the other end of the guide groove 104 extending to the first pipe segment 111.
