Abstract
Description
Technical Field
[0001] This application relates to the field of personal care technology, and more particularly to a nozzle and a personal care spraying device. Background Technology
[0002] Personal care spray devices (such as water flossers and nasal irrigators) are equipped with a power pump. The power pump is used to provide power for the flow of liquid in the liquid path of the personal care spray device, so that the liquid is sprayed out from the nozzle of the personal care spray device to achieve the cleaning function.
[0003] In related technologies, when using personal care spray devices to rinse between teeth, if the water flow rate is too high, first-time users and those with sensitive gums often experience gum bleeding or pain due to the strong impact, resulting in poor comfort and reduced product user experience. Utility Model Content
[0004] The main objective of this application is to provide a nozzle and a personal care spray device that effectively improves the cleaning effect of oral care and enhances the user experience of the product.
[0005] In a first aspect, this application provides a nozzle, comprising:
[0006] The nozzle component includes a body and a cleaning assembly. The body forms a receiving cavity with an inlet and an outlet. The cleaning assembly is movably connected to the body and is partially exposed to the body through the outlet. The cleaning assembly can undergo elastic deformation and can be displaced relative to the body in the axial direction to change the extension length of the cleaning assembly exposed to the body through the outlet.
[0007] The connecting rod assembly has one end connected to the end of the main body where the liquid inlet is formed, and the other end of the connecting rod assembly is used to connect to the main unit of the personal care spray device. The connecting rod assembly also has a liquid inlet channel communicating with the liquid inlet. The liquid flowing into the receiving cavity through the liquid inlet channel can be discharged from the main body through the liquid outlet.
[0008] In this embodiment, the cleaning component is movably connected to the main body and exposed through the liquid outlet. Furthermore, the cleaning component is elastically deformable and can displace relative to the main body in the axial direction. During the process of the main unit of the personal care spray device supplying liquid to the nozzle, the liquid flow exerts force on the cleaning component, causing it to elastically deform. This alters the extension and retraction length of the cleaning component exposed through the liquid outlet, allowing it to reciprocate and extend relative to the main body in the axial direction. This reciprocating cleaning component effectively cleans areas such as between teeth in the oral cavity. Simultaneously, under the action of the cleaning component, the liquid flow sprayed through the outlet passes through the gap between the cleaning component and the outlet, dispersing the liquid flow and forming an umbrella-shaped or near-umbrella-shaped water flow. This reduces the impact damage to the gums and removes small debris from between teeth, achieving a simultaneous cleaning and rinsing effect, thus greatly improving the cleaning power of the personal care spray device. In some embodiments, the body is provided with a limiting structure for limiting the displacement stroke of the cleaning component; or, after the nozzle component and the connecting rod component are connected, the connecting rod component and the body are adapted to form a limiting structure for limiting the displacement stroke of the cleaning component; wherein, under the limiting action of the limiting structure, the unidirectional displacement stroke corresponding to the displacement of the cleaning component in the axial direction of the body is S, and satisfies S≥1mm. Optionally, 5mm≥S≥1mm.
[0009] In this embodiment, by forming a limiting structure, the unidirectional displacement stroke corresponding to the displacement of the cleaning component in the axial direction of the body is limited to a preset stroke range, which allows the cleaning component to better remove residue from the gaps between the teeth.
[0010] In some embodiments, the cleaning component includes a cleaning element and an elastic element. The cleaning element is movably connected to the body and is partially exposed to the body through the liquid outlet. The elastic element can undergo elastic deformation and is elastically adapted to the cleaning element, so that the cleaning element can be displaced relative to the body in the axial direction under the action of external force, thereby changing the extension length of the cleaning element exposed to the body through the liquid outlet.
[0011] In this embodiment, by setting an elastic element and utilizing the elastic deformation characteristic of the elastic element, a driving force is provided for the displacement of the cleaning element relative to the body, thereby changing the extension and retraction length of the cleaning element exposed outside the body through the liquid outlet, so that the cleaning component can effectively clean areas such as the gaps between teeth in the oral cavity.
[0012] In some embodiments, in the initial state, the first end of the elastic member near the connecting rod member is in the first position of the body. When the first end is in the first position, the length of the cleaning member extending in the axial direction of the body is L1, and satisfies 20mm≥L1≥10mm.
[0013] In this embodiment, the axial extension length of the cleaning component is set within a preset range. This not only ensures that the length of the cleaning component extending beyond the body under the action of the elastic member is within a reasonable range, allowing the extension and retraction of the cleaning component to effectively clean areas such as between teeth in the oral cavity, but also avoids insufficient strength of the cleaning component due to excessive length. In some embodiments, the cleaning component includes a limiting part and a cleaning part. The limiting part is housed in the receiving cavity of the body and can be displaced relative to the body in the axial direction. The cleaning part is connected to the limiting part and is exposed outside the body through the liquid outlet portion. The elastic member is located between the limiting part and the body and is sleeved on the cleaning part.
[0014] In this embodiment, by setting a limiting part in the cleaning component, the limiting part and the body are adapted to limit the elastic component, so that when the liquid flows to the cleaning component, the cleaning component applies force to the elastic component, causing the elastic component to undergo elastic deformation, thereby changing the extension length of the cleaning component exposed outside the body through the liquid outlet, so as to clean the gaps between teeth.
[0015] In some embodiments, the limiting part is provided with a through hole, which connects the liquid inlet and the liquid outlet. Optionally, there are multiple through holes, which are distributed around the periphery of the cleaning part.
[0016] In this embodiment, the limiting part of the cleaning component is provided with a through hole, so that the liquid flowing in from the liquid inlet can flow through the through hole to the liquid outlet, so as to clean the gaps between teeth with the liquid sprayed through the liquid outlet.
[0017] Optionally, there are multiple through holes, which can split the liquid flow entering from the inlet into at least two streams, increasing the flow permeability of the liquid at the through holes and reducing the risk of liquid flow clogging the holes.
[0018] In some embodiments, the cleaning component includes a connecting section and a bristle-embedded section. The connecting section is connected to the limiting part, and an elastic element is sleeved on the connecting section. One end of the bristle-embedded section is connected to the connecting section and is exposed to the body through the liquid outlet portion. The bristle-embedded section is provided with bristles.
[0019] In this embodiment, by providing bristles in the bristle section of the cleaning component, the bristles can effectively increase the friction between the cleaning component and the contact area of the teeth, thereby enhancing the cleaning component's ability to clean areas such as gaps between teeth in the oral cavity.
[0020] In some embodiments, the elastic element is in a compressed state, and in the compressed state, there is a first distance L2 between the end of the hair-planting segment near the body and the end of the body where the liquid outlet is provided, and the distance L2 satisfies 5mm≥L2≥1mm.
[0021] In this embodiment, the elastic element has a compressed state and an extended state. In the compressed state, the elastic element stores elastic energy, and in the extended state, the elastic element can be compressed under the action of external force. Furthermore, when the elastic element is in the compressed state, there is a first distance within a preset range between the end of the bristle-planting section of the cleaning element near the main body and the end of the main body where the liquid outlet is provided, thereby effectively reducing the expansion and contraction resistance of the cleaning element.
[0022] In some implementations, the diameter of the hair-embedded segment is a first diameter, and the diameter of the liquid outlet is a second diameter. The difference X between the second diameter and the first diameter satisfies the condition that 0.7 mm ≥ X ≥ 0.05 mm.
[0023] In this embodiment, setting the diameter of the bristle section and the liquid outlet within a reasonable range not only ensures that the water jet from the nozzle has sufficient impact force, but also that the water jet can effectively remove residue from the tooth gaps.
[0024] In some implementations, the body and linkage components are detachably connected. This detachable connection improves the maintainability of the cleaning components.
[0025] Secondly, this application also provides a personal care spray device, including the aforementioned nozzle and a main unit connected to the nozzle.
[0026] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0037] Personal care spray devices (such as water flossers and nasal irrigators) are equipped with a power pump. The power pump is used to provide power for the flow of liquid in the liquid path of the personal care spray device, so that the liquid is sprayed out from the nozzle of the personal care spray device to achieve the cleaning function.
[0038] In related technologies, personal care spray devices typically use standard single-hole nozzles. The water jet from a single-hole nozzle is generally columnar, which can only ensure cleaning of a small area, resulting in low cleaning efficiency. In addition, the overly concentrated water jet may cause excessive force on the area to be cleaned, greatly reducing comfort and lowering the user experience of the personal care spray device.
[0039] To address the aforementioned technical problems, this application provides a nozzle and a personal care spraying device. The aim is that, after the personal care spraying device is adapted to the nozzle provided in this application, the cleaning efficiency of the personal care spraying device per unit time can be effectively increased, and the user experience of the personal care spraying device can be improved.
[0040] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0041] Please see Figures 1 to 2 , Figure 1 This is a three-dimensional structural diagram of the personal care spray device provided in this application.
[0042] like Figure 1 As shown, the personal care spray device 100 includes a main unit 10, a liquid storage tank 20 connected to the main unit 10, and a nozzle 30. The liquid storage tank 20 is used to store liquid, and the liquid storage tank 20 is provided with a liquid flow port. Users can add liquid into the liquid storage tank 20 through the liquid flow port, and the liquid storage tank 20 can also deliver liquid to the outside through the liquid flow port.
[0043] It is understood that there can be one or more fluid flow ports. For example, when there is one fluid flow port, it can serve as both an inlet and an outlet. When there are at least two fluid flow ports, at least one of them serves as an inlet and the other as an outlet.
[0044] like Figure 2 As shown, exemplarily, the liquid flow connection port of the liquid storage tank 20 includes a first liquid flow connection port 201 and a second liquid flow connection port 202. The user can add liquid into the liquid outlet tank through the first liquid flow connection port 201.
[0045] The host 10 can at least be used to provide power for the flow of liquid. Under the action of the host 10, the liquid in the storage tank 20 can flow to the host 10 through the second liquid flow port 202 and be sprayed out through the nozzle 30 adapted to the host 10 to clean the target object, which includes but is not limited to the user's mouth.
[0046] It is understood that users can add liquids stored in the reservoir 20 as needed. For example, liquids stored in the reservoir 20 include, but are not limited to, water, saline solution, and mouthwash; no specific limitation is made here.
[0047] Please see Figure 3 The nozzle 30 includes a spray head component 31 for ejecting liquid and a connecting rod component 32 for connecting the spray head component 31 and the main unit 10 of the personal care spray device 100. The connecting rod component 32 and the spray head component 31 are detachably connected, and the detachable connection can be achieved through methods including but not limited to threaded connection, interference fit, or structural engagement. For example, the spray head component 31 is provided with a first thread, and the connecting rod component 32 is provided with a second thread; the spray head component 31 is detachably connected and adapted to the second thread of the connecting rod component 32 via the first thread.
[0048] Please see Figures 4 to 8In some embodiments, the nozzle component 31 includes a body 311 and a cleaning assembly 312. The body 311 forms a receiving cavity 310 having an inlet 311a and an outlet 311b. The cleaning assembly 312 is movably connected to the body 311 and is partially exposed outside the body 311 through the outlet 311b. The cleaning assembly 312 is elastically deformable and can be displaced relative to the body 311 in the axial direction of the body 311 to change the extension length of the cleaning assembly 312 exposed outside the body 311 through the outlet 311b.
[0049] One end of the connecting rod component 32 is connected to one end of the main body 311 where the liquid inlet 311a is formed, and the other end of the connecting rod component 32 is used to connect to the main unit 10 of the personal care spray device 100. The connecting rod component 32 forms a liquid inlet channel 321 communicating with the liquid inlet 311a. The liquid flowing into the receiving cavity 310 through the liquid inlet channel 321 can be discharged from the main body 311 through the liquid outlet 311b. Optionally, the liquid inlet 311a and the liquid outlet 311b can be connected through a channel or through hole provided on the side wall of the receiving cavity 310. Optionally, the liquid inlet 311a and the liquid outlet 311b can also be connected through a channel or through hole provided in the cleaning component 312.
[0050] like Figure 7 As shown, under natural conditions, the external force on the cleaning component 312 in the axial direction of the body 311 is less than a preset value, so that the elastic deformation of the cleaning component 312 is less than the preset value or no elastic deformation occurs. At this time, the extension length of the part of the cleaning component 312 exposed to the body 311 through the liquid outlet 311b in the axial direction of the body 311 is X1.
[0051] like Figure 8 As shown, under compression, the external force on the cleaning component 312 in the axial direction of the body 311 is greater than a preset value, causing the cleaning component 312 to undergo elastic deformation. At this time, the extension length of the part of the cleaning component 312 exposed to the body 311 through the liquid outlet 311b in the axial direction of the body 311 is X2, and X2 > X1. Therefore, by intermittently or periodically adjusting the liquid supply to the nozzle component 31 by the main unit 10 of the personal care spray device 100, the force applied to the cleaning component 312 can be adjusted, thereby realizing the reciprocating movement of the cleaning component 312 in the axial direction of the body 311, that is, changing the extension length of the cleaning component 312 exposed to the body 311 through the liquid outlet 311b.
[0052] In this embodiment, the cleaning component 312 is movably connected to the body 311 and partially exposed on the body 311 through the liquid outlet 311b. Furthermore, the cleaning component 312 can undergo elastic deformation and can be displaced relative to the body 311 in the axial direction of the body 311. The liquid flow rate supplied by the main unit 10 of the personal care spray device 100 to the nozzle 30 can be controlled as needed. During the process of the main unit 10 of the personal care spray device 100 supplying liquid to the nozzle 30, the liquid flow applies force to the cleaning component 312, causing the cleaning component 312 to undergo elastic deformation. This changes the extension and retraction length of the cleaning component 312 exposed on the body 311 through the liquid outlet 311b, enabling the cleaning component 312 to reciprocate and extend relative to the body 311 in the axial direction of the body 311. Thus, the reciprocatingly extending and retracting cleaning component 312 can effectively clean areas such as the gaps between teeth in the oral cavity. Meanwhile, under the action of the cleaning component 312, the liquid sprayed through the outlet 311b is sprayed out through the gap between the cleaning component 312 and the outlet 311b, thereby dispersing the liquid flow and forming an umbrella-shaped or near-umbrella-shaped water flow, reducing the impact damage of the water flow on the gums, and can also remove small residues between teeth, achieving the effect of cleaning between teeth while rinsing, thus greatly improving the cleaning power of the personal care spray device 100.
[0053] In some embodiments, the body 311 and the connecting rod component 32 are detachably connected. This detachable connection between the body 311 and the connecting rod improves the maintainability of the cleaning unit 3121b. The detachable connection can be achieved through various means, including but not limited to threaded connections, interference fits, and structural locking. For example, the body 311 may have a first thread, and the connecting rod component 32 may have a second thread; the body 311 and the connecting rod component 32 can be detachably connected and adapted via the first thread and the second thread.
[0054] like Figure 4 As shown, in some embodiments, the body 311 is provided with a limiting structure 314 for limiting the displacement stroke of the cleaning component 312. Alternatively, after the nozzle component 31 and the connecting rod component 32 are connected, the connecting rod component 32 and the body 311 are adapted to form a limiting structure 314 for limiting the displacement stroke of the cleaning component 312. Under the limiting action of the limiting structure 314, the cleaning component 31 can reciprocate between the limiting structure 314 and the liquid outlet 311b, and the unidirectional displacement stroke corresponding to the displacement of the cleaning component 312 in the axial direction of the body 311 is S, and S≥1mm, for example, S is 1mm, 2mm, 3mm, 3.5mm, 4.6mm, etc., which is not limited here. Optionally, 5mm≥S≥1mm, for example, S is 1mm, 2mm, 3mm, 3.5mm, 4.6mm, etc., which is not limited here.
[0055] For example, after the nozzle component 31 and the connecting rod component 32 are connected, the end of the connecting rod component 32 cooperates with the inner wall of the receiving cavity 310 of the body 311 to form a limiting structure 314 for limiting the displacement stroke of the cleaning component 312. Under the action of the limiting structure 314, the cleaning component 312 can reciprocate between the limiting structure 314 and the liquid outlet 311b. Different displacement distances in the axial direction of the body 311 can make the length of the cleaning component 312 extending relative to the liquid outlet 311b different. Thus, during the oral cavity cleaning process of the personal care spray device 100, the cleaning component 312 can reciprocate and extend to rub against the gaps between teeth, thereby effectively cleaning the gaps between teeth and other areas in the oral cavity through the reciprocating cleaning component 312.
[0056] In this embodiment, by limiting the unidirectional displacement stroke corresponding to the displacement of the cleaning component 312 in the axial direction of the body 311 to a preset stroke range, the cleaning component 312 can better remove residue from the tooth gaps.
[0057] like Figure 6 As shown, in some embodiments, the cleaning component 312 includes a cleaning element 3121 and an elastic element 3122. The cleaning element 3121 is movably connected to the body 311 and is partially exposed to the body 311 through the liquid outlet 311b.
[0058] The elastic element 3122 can undergo elastic deformation and is elastically adapted to the cleaning element 3121. It is used to allow the cleaning element 3121 to be displaced relative to the body 311 in the axial direction of the body 311 under the action of external force, so as to change the extension length of the cleaning element 3121 exposed to the body 311 through the liquid outlet 311b. The elastic element 3122 includes, but is not limited to, springs, sheet metal, and elastic rubber.
[0059] In this embodiment, by providing an elastic element 3122 and utilizing the elastic deformation characteristic of the elastic element 3122, power is provided for the displacement of the cleaning element 3121 relative to the body 311, thereby changing the extension and retraction length of the cleaning element 3121 exposed to the body 311 through the liquid outlet 311b, so that the cleaning component 312 can effectively clean the gaps between teeth and other parts of the oral cavity.
[0060] It is understood that the adaptation methods of the elastic element 3122 and the cleaning element 3121 include, but are not limited to, the elastic element 3122 being sleeved on one end of the cleaning element 3121, or, one end of the elastic element 3122 being fixed to the cleaning element 3121 and the other end being able to abut against the body 311, or, one end of the elastic element 3122 being fixed to the body 311 and the other end being able to abut against the cleaning element 3121. As long as the elastic element 3122 and the cleaning element 3121 are adapted to the cleaning element, under the action of external force, the elastic element 3122 can be partially exposed to the body 31 through the liquid outlet 311b. When the external force is removed or the external force is less than the elastic deformation force, the elastic element 3122 can elastically reset, thereby allowing the cleaning element 3121 to return to its original position.
[0061] like Figure 7 As shown, optionally, in the initial state, the first end of the elastic member 3122 near the connecting rod member 32 is in the first position of the body 311. When the first end is in the first position, the extension length of the cleaning member 3121 in the axial direction of the body 311 is L1, and satisfies 20mm≥L1≥10mm. For example, L1 is 12mm, 15mm, 17mm, 18mm or 19.5mm, which is not limited here.
[0062] In this embodiment, the extension length of the cleaning member 3121 in the axial direction of the body 311 is set within a preset range. This not only ensures that the length of the cleaning member 3121 extending out of the body 311 under the action of the elastic member 3122 is within a reasonable range, so that the extension and retraction of the cleaning member 3121 can effectively clean the gaps between teeth and other parts of the oral cavity, but also avoids the cleaning member 3121 from being too long and thus having insufficient strength.
[0063] like Figure 6 As shown, in some embodiments, the cleaning member 3121 includes a limiting part 3121a and a cleaning part 3121b. The limiting part 3121a is housed in the receiving cavity 310 of the body 311 and can be displaced relative to the body 311 in the axial direction of the body 311. The cleaning part 3121b is connected to the limiting part 3121a and is partially exposed to the body 311 through the liquid outlet 311b. Optionally, the elastic member 3122 is located between the limiting part 3121a and the body 311 and is sleeved on the cleaning part 3121b.
[0064] In this embodiment, by providing a limiting part 3121a in the cleaning member 3121, the limiting part 3121a and the body 311 are adapted to limit the elastic member 3122, so that when the liquid flows to the cleaning member 3121, the cleaning member 3121 applies force to the elastic member 3122, causing the elastic member 3122 to undergo elastic deformation, thereby changing the extension length of the cleaning member 3121 exposed outside the body 311 through the liquid outlet 311b, so as to clean the gaps between teeth.
[0065] In some embodiments, the limiting part 3121a is provided with a through hole 3125, which connects the liquid inlet 311a and the liquid outlet 311b. Optionally, there are multiple through holes 3125, which are distributed around the periphery of the cleaning part 3121b. For example, three through holes 3125 are distributed in a triangular pattern on the limiting part 31.
[0066] In this embodiment, the limiting part 3121a of the cleaning component 3121 is provided with a through hole 3125, so that the liquid flowing in from the liquid inlet 311a can flow through the through hole 3125 to the liquid outlet 311b, so that the liquid sprayed through the liquid outlet 311b can clean the gaps between teeth.
[0067] Optionally, there are multiple through holes 3125, which can split the liquid flow entering from the liquid inlet 311a into at least two streams, increase the flowability of the liquid at the through holes 3125, and reduce the risk of liquid flow clogging.
[0068] like Figure 6 As shown, in some embodiments, the cleaning component 3121 includes a connecting section 3124 and a bristle-embedded section 3123. The connecting section 3124 is connected to the limiting portion 3121a, and the elastic component 3122 is sleeved on the connecting section 3124. One end of the bristle-embedded section 3123 is connected to the connecting section 3124 and partially exposed to the body 311 through the liquid outlet 311b. The bristle-embedded section 3123 is provided with bristles.
[0069] In this embodiment, by providing bristles in the bristle section 3123 of the cleaning component 3121, the bristles can effectively increase the friction between the cleaning component 3121 and the tooth contact area, thereby enhancing the cleaning ability of the cleaning component 3121 to clean areas such as the gaps between teeth in the oral cavity.
[0070] In some embodiments, the elastic member 3122 is in a compressed state, and when the elastic member 3122 is in a compressed state, there is a first distance L2 between the end of the hair-planting segment 3123 near the body 311 and the end of the body 311 where the liquid outlet 311b is provided, and the distance L2 satisfies 5mm≥L2≥1mm, for example, L2 is 1.5mm, 2mm, 3mm, 4mm, etc.
[0071] In this embodiment, the elastic member 3122 has a compressed state and an extended state. In the compressed state, the elastic member 3122 stores elastic energy, and in the extended state, the elastic member 3122 can be compressed under the action of external force. Furthermore, when the elastic member 3122 is in the compressed state, there is a first distance within a preset range between the end of the bristle section 3123 of the cleaning member 3121 near the body 311 and the end of the body 311 where the liquid outlet 311b is provided, thereby effectively reducing the expansion and contraction resistance of the cleaning member 3121.
[0072] In some embodiments, the diameter of the hair-embedded segment 3123 is a first diameter, and the diameter of the liquid outlet 311b is a second diameter. The difference X between the second diameter and the first diameter satisfies 0.7mm ≥ X ≥ 0.05mm. For example, X is 0.1mm, 0.2mm, 0.5mm, 0.6mm, etc.
[0073] For example, the first diameter D1 of the bristle implant 3123 is 0.3-0.7 mm, so that the bristle implant 3123 can effectively enter the interdental space for cleaning. For example, D1 is 0.3 mm, 0.4 mm, 0.5 mm, 0.7 mm, etc. The second diameter of the liquid outlet 311b is 0.75-1 mm, so that the nozzle has sufficient impact force, thereby enabling the liquid flow to effectively remove residue from the interdental space. For example, D2 is 0.75 mm, 0.77 mm, 0.8 mm, 1.0 mm, etc.
