Description

Technical Field

[0001] The present application relates to the technical field of personal care, and particularly relates to a nozzle and a personal care spraying device. Background Art

[0002] A power pump is provided in a personal care spraying device (such as a dental irrigator, a nasal irrigator, etc.). The power pump is arranged inside the personal care spraying device and is used to provide power for the flow of liquid in the liquid path of the personal care spraying device, so that the liquid is ejected from the nozzle of the personal care spraying device to achieve the cleaning function.

[0003] In the related art, the nozzle of a personal care spraying device usually adopts a standard single-hole nozzle. The water flow pattern ejected by the single-hole nozzle is generally columnar, which can only ensure the cleaning of a small area of the part to be cleaned, and the cleaning efficiency is low. In addition, the overly concentrated water flow may cause too much impact force on the part to be cleaned, and the comfort level is also greatly reduced, thus reducing the product use experience of the personal care spraying device. Utility Model Content

[0004] The main purpose of the embodiments of the present application is to provide a nozzle and a personal care spraying device, aiming to effectively increase the cleaning efficiency of the personal care spraying device per unit time and improve the product use experience of the personal care spraying device after the personal care spraying device is adapted to the nozzle provided by the present application.

[0005] In a first aspect, the present application provides a nozzle, including:

[0006] A nozzle head, the nozzle head is provided with a first liquid outlet, a second liquid outlet, a first liquid flow channel and a second liquid flow channel; the first liquid outlet and the second liquid outlet are arranged at intervals, and the first liquid flow channel is communicated with the first liquid outlet, and the second liquid flow channel is communicated with the second liquid outlet;

[0007] A connecting rod component, one end of the connecting rod component is connected to the nozzle head, the other end of the connecting rod component is used for connection and adaptation with the main body of the personal care spraying device, and the connecting rod component is formed with a liquid inlet flow channel communicated with the first liquid flow channel and the second liquid flow channel;

[0008] Wherein, the minimum flow channel aperture in the first liquid flow channel is a first aperture, the minimum flow channel aperture in the second liquid flow channel is a second aperture, and the minimum flow channel aperture in the liquid inlet flow channel is a third aperture; both the first aperture and the second aperture are smaller than the third aperture; and, the nozzle head can be deformed during the ejection process of the liquid through the first liquid outlet and the second liquid outlet.

[0009] As can be seen from the technical solutions provided in the present application above, the nozzle provided in the present application has a first liquid outlet and a second liquid outlet provided at the nozzle head, and the formation of a double-line water flow through the two liquid outlets can effectively increase the cleaning range of the part to be cleaned. It can also improve the cleaning efficiency of the user cleaning the part to be cleaned per unit time by using the personal care spraying device configured with the nozzle provided in the present application.

[0010] Meanwhile, based on the fact that the aperture of the liquid outlet flow channel provided in the nozzle head and connected to the first liquid outlet and the second liquid outlet is smaller than the aperture of the flow channel used for transporting the liquid in the connecting rod component, the double-line water flow output from the nozzle head has better cleaning ability.

[0011] Furthermore, based on the fact that the nozzle head can deform during the process of the liquid exiting through the first liquid outlet and the second liquid outlet provided in the nozzle head. When the pressure of the liquid transported by the main body of the personal care spraying device to the nozzle head through the connecting rod component is greater than a preset value, it will have a strong impact on the nozzle head, causing the nozzle head to deform so as to release the pressure inside the nozzle head. During the process of the nozzle head releasing the pressure, the water flow exiting through the first liquid outlet and the second liquid outlet provided in the nozzle head has a strong instantaneous impact, thereby further improving the cleaning ability of the personal care spraying device.

[0012] Even further, based on the fact that the nozzle head can deform during the process of the liquid exiting through the first liquid outlet and the second liquid outlet provided in the nozzle head. Therefore, the deformation of the nozzle head can be controlled by controlling the liquid outlet effect of the main body of the personal care spraying device, and further the adjustment of the water flow outlet effect by the nozzle head can be realized. Furthermore, the personal care spraying device can have multiple water flow outlet effects after being configured with the nozzle provided in the present application, so as to meet the water flow outlet requirements of different users, and finally the product use experience of the personal care spraying device can be effectively improved.

[0013] Optionally, the distance D between the first liquid outlet and the second liquid outlet satisfies 5mm≥D≥0.2mm.

[0014] Based on the fact that the smaller the distance between the first liquid outlet and the second liquid outlet, the better the liquid outlet convergence effect of the nozzle head, and the cleaning effect of the personal care spraying device can be effectively improved. However, if the distance between the first liquid outlet and the second liquid outlet is too small, the liquid flows exiting through the two liquid outlets may converge to form a single-line liquid flow, affecting the cleaning efficiency of the personal care spraying device. At the same time, if the distance between the first liquid outlet and the second liquid outlet is too large, the liquid outlet convergence effect is poor, resulting in the attenuation of the cleaning ability of the personal care spraying device.

[0015] In this embodiment, by appropriately setting the distance D between the first liquid outlet and the second liquid outlet, after the nozzle is adapted to the personal care spraying device, the cleaning ability and cleaning efficiency of the personal care spraying device can be taken into account simultaneously.

[0016] Optionally, the first liquid outlet and the second liquid outlet have the same shape and size.

[0017] In this embodiment, by setting the shapes and sizes of the first liquid outlet and the second liquid outlet to be the same, the liquid flows ejected from the first liquid outlet and the second liquid outlet can have high consistency.

[0018] Optionally, the first liquid outlet is formed with a first arc structure, and the maximum distance W1 between any endpoint on the first arc structure and a first target point on the first arc structure satisfies 1.4 mm ≥ W1 ≥ 0.4 mm, where the first target point is the point on the first arc structure that is farthest from any endpoint on the first arc structure;

[0019] Optionally, the second liquid outlet is formed with a second arc structure, and the maximum distance W2 between any endpoint on the second arc structure and a second target point on the second arc structure satisfies 1.4 mm ≥ W2 ≥ 0.4 mm, where the second target point is the point on the second arc structure that is farthest from any endpoint on the second arc structure.

[0020] In this embodiment, by reasonably setting the radius of the first arc structure of the first liquid outlet and the second liquid outlet, the liquid outlet diameters of the first liquid outlet and the second liquid outlet can be set within a reasonable range. Thus, after the nozzle is adapted to the personal care spraying device, the cleaning ability of the personal care spraying device can be improved, and good liquid outlet comfort can be achieved.

[0021] Optionally, the first liquid flow channel includes a first sub-channel and a second sub-channel. The first sub-channel is communicated with the first liquid outlet, and the second sub-channel communicates the first sub-channel and the liquid inlet channel; wherein, the aperture of the second sub-channel is larger than that of the first sub-channel.

[0022] In this embodiment, since the aperture of the second sub-channel is larger than that of the first sub-channel, the first sub-channel can converge the liquid flow output by the second sub-channel, thereby effectively enhancing the cleaning effect of the liquid ejected from the first liquid outlet communicated with the first sub-channel on the part to be cleaned.

[0023] Optionally, the second liquid flow channel includes a third sub-channel and a fourth sub-channel. The third sub-channel is communicated with the second liquid outlet, and the fourth sub-channel communicates the second sub-channel and the liquid inlet channel; wherein, the flow channel aperture of the fourth sub-channel is larger than that of the third sub-channel.

[0024] Based on the fact that the aperture of the fourth sub-channel is larger than that of the third sub-channel, the third sub-channel can converge the liquid flow output by the fourth sub-channel, thereby effectively enhancing the cleaning effect on the part to be cleaned by the liquid flowing out from the second liquid outlet communicated with the third sub-channel.

[0029] Optionally, the flow channel aperture of the first sub-channel is equal to the flow channel aperture of the third sub-channel, and the flow channel aperture of the second sub-channel is equal to the flow channel aperture of the fourth sub-channel.

[0030] In this embodiment, based on the fact that the flow channel aperture of the first sub-channel is equal to the flow channel aperture of the third sub-channel, and the flow channel aperture of the second sub-channel is equal to the flow channel aperture of the fourth sub-channel, the consistency of the liquid flows output from the first liquid outlet and the second liquid outlet can be effectively improved.

[0031] Optionally, the first sub-channel extends along the axis direction of the nozzle for a first distance, the second sub-channel extends along the axis direction of the nozzle for a second distance, and the second distance is greater than the first distance.

[0032] Optionally, the third sub-channel extends along the axis direction of the nozzle for a third distance, the fourth sub-channel extends along the axis direction of the nozzle for a fourth distance, and the fourth distance is greater than the third distance.

[0033] Optionally, the first distance X1 satisfies 3mm ≥ X1 > 0 mm, and the second distance X2 satisfies 5mm ≥ X2 ≥ 0.5 mm;

[0034] Based on the fact that the nozzle can be deformed, by reasonably setting the extension lengths of the first sub-channel and the second sub-channel extending along the axis of the nozzle, the deformation of the nozzle can be within a preset range, avoiding excessive deformation of the nozzle resulting in excessive loss of the impact force of the liquid flow output through the first liquid outlet.

[0035] Optionally, the third distance X3 satisfies 3 mm ≥ X3 > 0 mm, and the fourth distance X4 satisfies 5 mm ≥ X4 ≥ 0.5 mm.

[0036] By reasonably setting the extension lengths of the third sub-channel and the fourth sub-channel extending along the axis of the nozzle, the deformation of the nozzle can be within a preset range, avoiding excessive deformation of the nozzle resulting in excessive loss of the impact force of the liquid flow output through the second liquid outlet.

[0037] Optionally, the connection between the second sub-channel and the first sub-channel has a tapered transition from large to small along the extension direction of the link member.

[0038] In this embodiment, based on the fact that the aperture of the second sub-channel is larger than that of the first sub-channel, and the connection between the second sub-channel and the first sub-channel has a tapered transition, the resistance of the liquid flow from the second sub-channel to the first sub-channel can be effectively reduced, and the converging effect of the first sub-channel on the liquid flow output from the second sub-channel can be further enhanced.

[0039] Optionally, the connection between the third sub-channel and the fourth sub-channel has a tapered transition from large to small along the extension direction of the link member.

[0040] In this embodiment, based on the fact that the aperture of the fourth sub-channel is larger than that of the third sub-channel, and the connection between the fourth sub-channel and the third sub-channel has a tapered transition, the resistance of the liquid flow from the fourth sub-channel to the third sub-channel can be effectively reduced, and the converging effect of the third sub-channel on the liquid flow output from the fourth sub-channel can be further enhanced.

[0041] Optionally, the link member includes a connecting rod and a nozzle rod; the connecting rod is connected to the nozzle and has at least one first channel communicating with the first liquid outlet channel and the second liquid outlet channel; one end of the nozzle rod is connected to the end of the connecting rod away from the nozzle, and the other end of the nozzle rod is used to connect to the main body of the personal care spraying device; wherein, the nozzle rod has at least one second channel communicating with the first channel, and the first channel and the second channel communicate to form the liquid inlet channel.

[0042] In this embodiment, a connecting rod is used to connect the nozzle rod and the nozzle head, and the first flow channel formed by the connecting rod communicates with the second flow channel of the nozzle rod, the first liquid outlet flow channel and the second liquid outlet flow channel of the nozzle head. By means of the transfer and buffering of the first flow channel, the liquid flows output from the first liquid outlet and the second liquid outlet of the nozzle head can have stronger stability.

[0043] Optionally, the nozzle head is a soft rubber nozzle head, and the hardness of the connecting rod is greater than that of the nozzle head.

[0044] Optionally, the hardness of the nozzle rod is greater than that of the nozzle head.

[0045] In this embodiment, based on the fact that the hardness of at least one of the connecting rod and the nozzle rod is greater than that of the nozzle head, when the nozzle head deforms, it can provide a rigid support for the nozzle head, so that the direction of the liquid flow ejected by the nozzle head can be controlled.

[0046] Optionally, the connecting rod is detachably connected to the nozzle head.

[0047] In this embodiment, through the detachable connection, the convenient disassembly, installation and replacement of the nozzle head can be realized.

[0048] Optionally, the connecting rod is detachably connected to the nozzle rod.

[0049] In this embodiment, through the detachable connection, the convenient disassembly, installation and replacement of the nozzle head and the nozzle rod can be realized.

[0050] Optionally, the flow channel aperture of the second flow channel is greater than that of the first flow channel.

[0051] In this embodiment, based on the fact that the flow channel aperture of the second flow channel is greater than that of the first flow channel, and the flow channel aperture of the first flow channel is greater than the flow channel apertures of the first liquid outlet flow channel and the second liquid outlet flow channel, after the liquid output by the host passes through the convergence of the second flow channel and the first flow channel, the liquid flows output from the first liquid outlet flow channel and the second liquid outlet flow channel can have a better convergence effect.

[0052] Optionally, there are at least two first flow channels formed by the connecting rod. Among them, at least one first flow channel communicates with the first liquid outlet flow channel and the second flow channel, and at least one first flow channel communicates with the second liquid outlet flow channel and the second flow channel.

[0053] In this embodiment, by independently providing corresponding first flow channels for the first liquid outlet flow channel and the second liquid outlet flow channel, and using the respective first flow channels to provide liquid flows for the corresponding first liquid outlet flow channel and the second liquid outlet flow channel, the liquid flows of the first liquid outlet flow channel and the second liquid outlet flow channel can have stronger stability.

[0054] Optionally, the channel aperture of the first flow channel on the side close to the nozzle rod is larger than the channel aperture of the first flow channel on the side close to the nozzle head.

[0055] In this embodiment, based on the fact that the channel aperture of the first flow channel on the side close to the nozzle rod is larger than the channel aperture of the first flow channel on the side close to the nozzle head, the first flow channel has a stronger converging effect on the liquid flow.

[0056] In a second aspect, the present application provides a personal care spraying device, including the aforementioned nozzle and a main body connected to the nozzle.

[0057] As can be seen from the technical solutions provided by the present application above, the nozzle of the personal care spraying device is provided with a first liquid outlet and a second liquid outlet at the nozzle head.

[0058] Forming a double-line water flow through the two liquid outlets can effectively increase the cleaning range of the part to be cleaned, thereby improving the cleaning efficiency of the user cleaning the part to be cleaned by using the personal care spraying device configured with the nozzle provided by the present application per unit time.

[0059] At the same time, based on the fact that the aperture of the liquid outlet flow channel provided in the nozzle head and connected to the first liquid outlet and the second liquid outlet is smaller than the aperture of the flow channel of the connecting rod component for transporting the liquid, the double-line water flow output from the nozzle head has good cleaning ability.

[0060] Furthermore, based on the fact that the nozzle head can be deformed during the process of the liquid exiting through the first liquid outlet and the second liquid outlet provided in the nozzle head.

[0061] When the pressure of the liquid transported by the main body of the personal care spraying device to the nozzle head through the connecting rod component is greater than a preset value, it will have a strong impact on the nozzle head, causing the nozzle head to deform and release the pressure inside the nozzle head. During the process of the nozzle head releasing the pressure, the water flow exiting through the first liquid outlet and the second liquid outlet provided in the nozzle head has a strong instantaneous impact, thereby further improving the cleaning ability of the personal care spraying device.

[0062] Even further, based on the fact that the nozzle head can be deformed during the process of the liquid exiting through the first liquid outlet and the second liquid outlet provided in the nozzle head. Therefore, the deformation of the nozzle head can be controlled by controlling the liquid outlet effect of the main body of the personal care spraying device, and further the adjustment of the water flow outlet effect of the nozzle head can be realized, so that the personal care spraying device has various water flow outlet effects after being configured with the nozzle provided by the present application, to meet the water flow outlet requirements of different users, and finally the product use experience of the personal care spraying device can be effectively improved.

[0072] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some, rather than all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present application.

[0073] A power pump is provided in a personal care spraying device (such as a dental irrigator, a nasal irrigator, etc.). A power pump is provided inside the personal care spraying device, which is used to provide power for the liquid to flow in the liquid path of the personal care spraying device, so that the liquid is ejected from the nozzle of the personal care spraying device to achieve the cleaning function.

[0074] In the related art, the nozzle of a personal care jet device usually adopts a standard single-hole nozzle. The water flow pattern ejected by the single-hole nozzle is generally columnar, which can only ensure the cleaning of a small area of the part to be cleaned, and the cleaning efficiency is low. In addition, the overly concentrated water flow may cause too much impact force on the part to be cleaned, and the comfort is also greatly reduced, thus reducing the product use experience of the personal care jet device.

[0075] To solve the above technical problems, the present application provides a nozzle and a personal care jet device, aiming to effectively increase the cleaning efficiency of the personal care jet device per unit time and improve the product use experience of the personal care jet device after the personal care jet device is adapted to the nozzle provided by the present application.

[0076] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0077] Please refer to Figures 1 to 2 , Figure 1 which is a schematic three-dimensional structure diagram of the personal care jet device provided by the present application.

[0078] As Figure 1 shown, the personal care jet device 100 includes a main body 10, a liquid storage tank 20 connected to the main body 10, and a nozzle 30. Among them, the liquid storage tank 20 is used to store liquid, and the liquid storage tank 20 is provided with a liquid flow communication port. The user can add liquid into the liquid storage tank 20 through the liquid flow communication port, and the liquid storage tank 20 can also transport liquid to the outside through the liquid flow communication port.

[0079] It can be understood that the liquid flow communication port can be one or more. For example, when the liquid flow communication port is one, the liquid flow communication port can be used as both an inlet and an outlet. When the liquid flow communication port is at least two, at least one of the liquid flow communication ports is used as an inlet, and the other liquid flow communication port is used as an outlet.

[0080] As Figure 2 shown, exemplarily, the liquid flow communication ports of the liquid storage tank 20 include a first liquid flow communication port 201 and a second liquid flow communication port 202. The user can add liquid into the liquid storage tank through the first liquid flow communication port 201.

[0081] The main body 10 can at least be used to provide power for the liquid flow. Under the action of the main body 10, the liquid in the liquid storage tank 20 can flow to the main body 10 through the second liquid flow communication port 202 and be ejected through the nozzle 30 adapted to the main body 10 to clean the target object, and the target object includes but is not limited to the user's oral cavity and nasal cavity.

[0082] It is understandable that the liquid stored in the liquid storage tank 20 can be added by the user as needed. For example, the liquid stored in the liquid storage tank 20 includes but is not limited to water, physiological saline, and mouthwash, and is not limited here.

[0083] Please refer to Figures 3 to 8 , the nozzle 30 includes a nozzle head 31 for ejecting liquid and a connecting rod member 32 for connecting the nozzle head 31 and the main body 10 of the personal care spraying device 100.

[0084] Specifically, the nozzle head 31 is provided with a first liquid outlet 311, a second liquid outlet 312, a first liquid flow channel 313 and a second liquid flow channel 314. The first liquid outlet 311 and the second liquid outlet 312 are arranged at intervals, and the first liquid flow channel 313 is communicated with the first liquid outlet 311, and the second liquid flow channel 314 is communicated with the second liquid outlet 312.

[0085] One end of the connecting rod member 32 is connected to the nozzle head 31, the other end of the connecting rod member 32 is used for connecting and adapting to the main body of the personal care spraying device, and the connecting rod member 32 is formed with a liquid inlet flow channel 320 communicated with the first liquid flow channel 313 and the second liquid flow channel 314.

[0086] Wherein, the minimum flow channel aperture in the first liquid flow channel 313 is the first aperture, the minimum flow channel aperture in the second liquid flow channel 314 is the second aperture, and the minimum flow channel aperture in the liquid inlet flow channel 320 is the third aperture.

[0087] Both the first aperture and the second aperture are smaller than the third aperture; and, the nozzle head 31 can be deformed during the process of ejecting liquid through the first liquid outlet 311 and the second liquid outlet 312.

[0088] In this embodiment, the nozzle 30 is provided with a first liquid outlet 311 and a second liquid outlet 312 at the nozzle head 31. By forming a double-line water flow through the two liquid outlets, the cleaning range of the part to be cleaned can be effectively increased, so that the cleaning efficiency of the user cleaning the part to be cleaned by using the personal care spraying device 100 configured with the nozzle 30 provided in the present application per unit time can be improved.

[0089] At the same time, based on the fact that the aperture of the liquid flow channel arranged in the nozzle head 31 and connected to the first liquid outlet 311 and the second liquid outlet 312 is smaller than the aperture of the liquid flow channel arranged in the connecting rod member 32 for transporting liquid. Thus, the double-line water flow output from the nozzle head has better cleaning ability.

[0090] Further, the nozzle 31 can deform during the liquid ejection through the first liquid outlet 311 and the second liquid outlet 312 provided on the nozzle 31. That is, when the pressure of the liquid delivered from the main body 10 of the personal care spraying device 100 to the nozzle 31 through the link member 32 is greater than a preset value, there will be a strong impact on the nozzle 31, causing the nozzle 31 to deform so as to release the pressure inside the nozzle 31. During the pressure release process of the nozzle 31, the water flow ejected through the first liquid outlet 311 and the second liquid outlet 312 provided on the nozzle 31 has a strong instantaneous impact, thereby further improving the cleaning ability of the personal care spraying device 100.

[0091] Furthermore, the nozzle 31 can deform during the liquid ejection through the first liquid outlet 311 and the second liquid outlet 312 provided on the nozzle 31.

[0092] Therefore, the deformation of the nozzle 31 can be controlled by controlling the liquid ejection effect of the main body 10 of the personal care spraying device 100, and then the adjustment of the water flow ejection effect of the nozzle 31 can be realized, so that the personal care spraying device 100 has various water flow ejection effects after being configured with the nozzle 30 provided in the present application to meet the water flow ejection requirements of different users, and finally the product use experience of the personal care spraying device 100 can be effectively improved.

[0093] As Figures 5 to 8 shown, in some embodiments, the distance D between the first liquid outlet 311 and the second liquid outlet 312 satisfies 5 mm ≥ D ≥ 0.2 mm. Wherein, the distance D between the first liquid outlet 311 and the second liquid outlet 312 may refer to the distance between the edge of the first liquid outlet 311 closest to the second liquid outlet 312 and the edge of the second liquid outlet 312 closest to the first liquid outlet 311. The distance D may also be the distance between the center point of the first liquid outlet 311 and the center point of the second liquid outlet 312. For example, the distance D between the first liquid outlet 311 and the second liquid outlet 312 may be 0.5 mm, 1 mm, 2 mm, 3 mm, 3.5 mm or 4 mm.

[0094] Based on the fact that the smaller the distance between the first liquid outlet 311 and the second liquid outlet 312, the better the liquid ejection convergence effect of the nozzle 31, which can effectively improve the cleaning effect of the personal care spraying device. However, if the distance between the first liquid outlet 311 and the second liquid outlet 312 is too small, the liquid flows ejected through the two liquid outlets may converge to form a single-line liquid flow, affecting the cleaning efficiency of the personal care spraying device. At the same time, if the distance between the first liquid outlet 311 and the second liquid outlet 312 is too large, the liquid ejection convergence effect is poor, resulting in the attenuation of the cleaning ability of the personal care spraying device 100.

[0095] In this embodiment, by appropriately setting the distance D between the first liquid outlet 311 and the second liquid outlet 312, after the nozzle 30 is adapted to the personal care spraying device 100, the cleaning ability and cleaning efficiency of the personal care spraying device 100 can be taken into account simultaneously.

[0096] Optionally, the first liquid outlet 311 and the second liquid outlet 312 have the same shape and size. For example, the shapes of the first liquid outlet 311 and the second liquid outlet 312 include, but are not limited to, circular, elliptical, D-shaped, crescent-shaped, and polygonal.

[0097] Optionally, the first liquid outlet 311 and the second liquid outlet 312 can be set to have the same shape and size, so that the liquid flows ejected from the first liquid outlet 311 and the second liquid outlet 312 have high consistency.

[0098] Optionally, at least one of the shape and size of the first liquid outlet 311 and the second liquid outlet 312 is different, so that the liquid flows ejected from the first liquid outlet 311 and the second liquid outlet 312 have more liquid ejection effects, which can meet the cleaning requirements of different parts to be cleaned. For example, for the oral gingival part, in order to improve the user's brushing comfort, a weaker liquid flow may be required, and the liquid can be ejected through a larger liquid outlet to reduce the liquid flow convergence. For the tooth part, a stronger liquid flow may be required, and the liquid can be ejected through a smaller liquid outlet to increase the liquid flow convergence.

[0099] In some embodiments, the first liquid outlet 311 is formed with a first arc structure, and the radius R1 of the first arc structure satisfies 0.7 mm ≥ R1 ≥ 0.2 mm. For example, R1 can be 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, or 0.7 mm.

[0100] In some embodiments, the second liquid outlet 312 is formed with a second arc structure, and the radius R2 of the second arc structure satisfies 0.7 mm ≥ R2 ≥ 0.2 mm. For example, R2 can be 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, or 0.7 mm.

[0101] Optionally, the first arc structure is disposed on a side of the first liquid outlet 311 away from the second liquid outlet 312, and / or the second arc structure is disposed on a side of the second liquid outlet 312 away from the first liquid outlet 311.

[0102] In some embodiments, the first liquid outlet is formed with a first arc structure, and the maximum distance W1 between any endpoint on the first arc structure and a first target point on the first arc structure satisfies 1.4 mm ≥ W1 ≥ 0.4 mm. The first target point is the point on the first arc structure that is farthest from any endpoint on the first arc structure.

[0103] As shown Figure 7 in FIG. 3, a first liquid outlet 311 is formed with a first arc structure 3111. The first arc structure 3111 has two opposite end points, namely a first end point A and a second end point B. Moreover, the maximum distance between the first end point A of the first arc structure 3111 and the point X1 on the first arc structure 3111 that is farthest from the first end point A is W1. For example, when the point X1 that is farthest from the first end point A is the second end point B, the maximum distance between the first end point A and the second end point B is W1, 1.4 mm ≥ W1 ≥ 0.4 mm, and W1 can be 0.4 mm, 0.7 mm, 0.8 mm, 1.0 mm, 1.2 mm or 1.4 mm.

[0104] In some embodiments, the second liquid outlet is formed with a second arc structure.

The second target point is the point on the second arc structure that is farthest from any end point on the second arc structure.

[0105] As shown Figure 7 in FIG. 4, a second liquid outlet 312 is formed with a second arc structure 3121. The second arc structure 3121 has two opposite end points, namely a first end point C and a second end point D. Moreover, the maximum distance between the first end point C of the second arc structure 3121 and the point X2 on the second arc structure 3121 that is farthest from the first end point C is W2.

[0106] Optionally, the first arc structure is disposed on a side of the first liquid outlet 311 away from the second liquid outlet 312, and / or the second arc structure is disposed on a side of the second liquid outlet 312 away from the first liquid outlet 311, as shown Figure 7 in FIG. 5.

[0107] Exemplarily, the first liquid outlet 311 can be a structure that is at least partially arc-shaped, such as circular, oval, D-shaped, semi-circular, etc., and the second liquid outlet 312 can also be a structure that is at least partially arc-shaped, such as circular, oval, D-shaped, semi-circular, etc.

[0108] By reasonably setting the radius of the first arc structure of the first liquid outlet 311 and the second liquid outlet 312, the liquid outlet diameters of the first liquid outlet 311 and the second liquid outlet 312 can be set within a reasonable range. Thus, after the nozzle 30 is adapted to the personal care spraying device 100, the cleaning ability of the personal care spraying device 100 can be improved, and better liquid outlet comfort can be achieved.

[0109] As Figures 5 to 8 shown, in some embodiments, the first liquid flow channel 313 includes a first sub-channel 3131 and a second sub-channel 3132. The first sub-channel 3131 is communicated with the first liquid outlet 311, and the second sub-channel 3132 communicates the first sub-channel 3131 and the liquid inlet channel 320; wherein, the aperture of the second sub-channel 3132 is larger than that of the first sub-channel 3131.

[0110] Based on the fact that the aperture of the second sub-channel 3132 is larger than that of the first sub-channel 3131, therefore, the first sub-channel 3131 can converge the liquid flow output by the second sub-channel 3132, thereby effectively enhancing the cleaning effect of the liquid flowing out from the first liquid outlet 311 communicated with the first sub-channel 3131 on the part to be cleaned.

[0111] Optionally, the connection between the second sub-channel 3132 and the first sub-channel 3131 has a tapered transition from large to small along the extension direction of the link member 32.

[0112] Based on the fact that the aperture of the second sub-channel 3132 is larger than that of the first sub-channel 3131, and the connection between the second sub-channel 3132 and the first sub-channel 3131 has a tapered transition, the resistance of the liquid flow from the second sub-channel 3132 to the first sub-channel 3131 can be effectively reduced, and the converging effect of the first sub-channel 3131 on the liquid flow output by the second sub-channel 3132 can be further enhanced.

[0113] Optionally, the channel aperture of the first sub-channel 3131 is the same as the shape and size of the first liquid outlet 311.

[0114] Optionally, the channel aperture d1 of the first sub-channel 3131 satisfies 0.7mm≥d1≥0.2mm; and the channel aperture d2 of the second sub-channel 3132 satisfies 5mm≥d2≥1mm. For example, d1 can be any one of 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, and d2 can be any one of 1mm, 1.5mm, 2mm, 3mm, 4mm, 4.5mm, 5mm.

[0115] Optionally, the first sub-channel 3131 extends a first distance along the axis direction of the nozzle 31, and the second sub-channel 3132 extends a second distance along the axis direction of the nozzle 31, and the second distance is greater than the first distance.

[0116] Optionally, the first distance X1 that the first sub-channel 3131 extends along the axis direction of the nozzle 31 satisfies 3 mm ≥ X1 > 0 mm, and the second distance X2 that the second sub-channel 3132 extends along the axis direction of the nozzle 31 satisfies 5 mm ≥ X2 ≥ 0.5 mm. For example, X1 can be any one of 0.2 mm, 0.5 mm, 1 mm, 2 mm, 2.5 mm, 3 mm, and X2 can be any one of 0.5 mm, 1 mm, 2 mm, 3 mm, 3.5 mm, 4.5 mm, 5 mm.

[0117] Based on the fact that the nozzle 31 can be deformed, by reasonably setting the sizes of the flow channel apertures and the extension lengths corresponding to the first sub-channel 3131 and the second sub-channel 3132 along the axis direction of the nozzle 31, the deformation of the nozzle 31 can be within a preset range, avoiding excessive loss of the impact force of the liquid flow output through the first liquid outlet 311 due to excessive deformation of the nozzle 31.

[0118] In some embodiments, the second liquid outlet channel 314 includes a third sub-channel 3141 and a fourth sub-channel 3142. The third sub-channel 3141 communicates with the second liquid outlet 312, and the fourth sub-channel 3142 communicates with the second sub-channel 3132 and the liquid inlet channel 320; wherein, the flow channel aperture of the fourth sub-channel 3142 is larger than that of the third sub-channel 3141.

[0119] Based on the fact that the flow channel aperture of the fourth sub-channel 3142 is larger than that of the third sub-channel 3141, therefore, the third sub-channel 3141 can converge the liquid flow output by the fourth sub-channel 3142, thereby effectively enhancing the cleaning effect on the part to be cleaned by the liquid flowing out through the second liquid outlet 312 communicating with the third sub-channel 3141.

[0120] Optionally, the connection between the third sub-channel 3141 and the fourth sub-channel 3142 has a tapered transition from large to small along the extension direction of the link member 32.

[0121] Based on the fact that the flow channel aperture of the fourth sub-channel 3142 is larger than that of the third sub-channel 3141, and the connection between the third sub-channel 3141 and the fourth sub-channel 3142 has a tapered transition, the resistance of the liquid flow from the fourth sub-channel 3142 to the third sub-channel 3141 can be effectively reduced, further enhancing the converging effect of the third sub-channel 3141 on the liquid flow output by the fourth sub-channel 3142.

[0122] Optionally, the third sub-channel 3141 has the same shape and size as the second liquid outlet 312.

[0123] Optionally, the flow channel aperture d3 of the third sub-channel 3141 satisfies 0.7 mm ≥ d3 ≥ 0.2 mm; and the flow channel aperture d4 of the fourth sub-channel 3142 satisfies 5 mm ≥ d4 ≥ 1 mm. For example, d3 can be any one of 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, and d4 can be any one of 1 mm, 1.5 mm, 2 mm, 3 mm, 4 mm, 4.5 mm, 5 mm.

[0124] Optionally, the third sub-channel 3141 extends along the axis direction of the nozzle 31 for a third distance, and the fourth sub-channel 3142 extends along the axis direction of the nozzle 31 for a fourth distance, and the fourth distance is greater than the third distance.

[0125] Optionally, the third distance X3 that the third sub-channel 3141 extends along the axis direction of the nozzle 31 satisfies 3 mm ≥ X3 > 0 mm, and the fourth distance X4 that the fourth sub-channel 3142 extends along the axis direction of the nozzle 31 satisfies 5 mm ≥ X4 ≥ 0.5 mm. For example, X3 can be any one of 0.2 mm, 0.5 mm, 1 mm, 2 mm, 2.5 mm, 3 mm, and X4 can be any one of 0.5 mm, 1 mm, 2 mm, 3 mm, 3.5 mm, 4.5 mm, 5 mm.

[0126] Based on the fact that the nozzle 31 can be deformed, by reasonably setting the sizes of the flow channel apertures corresponding to the third sub-channel 3141 and the fourth sub-channel 3142 and the extension lengths extending along the axis direction of the nozzle 31, the deformation of the nozzle 31 can be within a preset range, avoiding excessive loss of the impact force of the liquid flow output through the second liquid outlet 312 due to excessive deformation of the nozzle 31.

[0127] In some embodiments, the flow channel aperture of the first sub-channel 3131 is equal to the flow channel aperture of the third sub-channel 3141, and the flow channel aperture of the second sub-channel 3132 is equal to the flow channel aperture of the fourth sub-channel 3142, so as to effectively improve the consistency of the liquid flows output through the first liquid outlet 311 and the second liquid outlet 312.

[0128] Such as Figures 5 to 8As shown, in some embodiments, the link member 32 includes a connecting rod 321 and a nozzle rod 322. The connecting rod 321 is connected to the nozzle head 31 and is formed with at least one first flow channel 3211 communicating with the first liquid outlet flow channel 313 and the second liquid outlet flow channel 314. One end of the nozzle rod 322 is connected to the end of the connecting rod 321 away from the nozzle head 31. The other end of the nozzle rod 322 is used to connect to the main body 10 of the personal care spraying device 100. Wherein, the nozzle rod 322 is formed with at least one second flow channel 3221 communicating with the first flow channel 3211, and the first flow channel 3211 and the second flow channel 3221 communicate to form a liquid inlet flow channel 320.

[0129] Optionally, the nozzle rod 322 is provided with a bending portion, which is arranged at one end of the nozzle rod 322 close to the connecting rod 321. It is convenient for the user to insert the nozzle head 31 into the part to be cleaned at a more comfortable angle through the link member 32 during the process of using the nozzle 30 to clean the part to be cleaned, and the part to be cleaned includes at least the oral cavity.

[0130] In this embodiment, the connecting rod 321 is used to connect the nozzle rod 322 and the nozzle head 31, and the first flow channel 3211 formed by the connecting rod 321 communicates with the second flow channel 3221 of the nozzle rod 322 and the first liquid outlet flow channel 313 and the second liquid outlet flow channel 314 of the nozzle head 31. The transfer buffering of the first flow channel 3211 can make the liquid flow output from the first liquid outlet 311 and the second liquid outlet 312 of the nozzle head 31 more stable.

[0131] It can be understood that the first flow channel 3211 formed by the connecting rod 321 can be one or more. There is no limitation here, as long as the second flow channel 3221 can communicate with the first liquid outlet flow channel 313 and the second liquid outlet flow channel 314 arranged on the nozzle head 31 through the first flow channel 3211, so as to supply liquid to the first liquid outlet flow channel 313 and the second liquid outlet flow channel 314.

[0132] Optionally, the connecting rod 321 is detachably connected to the nozzle head 31, and / or the connecting rod 321 is detachably connected to the nozzle rod 322.

[0133] It can be understood that the ways of the detachable connection between the connecting rod 321 and the nozzle head 31 include but are not limited to interference fit, screw connection, structural clamping, etc. The ways of the detachable connection between the connecting rod 321 and the nozzle rod 322 include but are not limited to interference fit, screw connection, structural clamping, etc. Through the detachable connection, the convenient disassembly, replacement of the nozzle head 31, the connecting rod 321 or the nozzle rod 322 can be realized.

[0134] In some embodiments, the nozzle head 31 is a soft rubber nozzle head, and the hardness of the connecting rod 321 is greater than the hardness of the nozzle head 31, and / or the hardness of the nozzle rod 322 is greater than the hardness of the nozzle head 31.

[0135] Exemplarily, the soft rubber nozzle includes, but is not limited to, a silicone nozzle, a PP glue nozzle, and a PE glue nozzle. Based on the hardness of at least one of the connecting rod 321 and the nozzle rod 322 being greater than that of the nozzle 31, the nozzle 31 can be given a rigid support during the deformation process, so that the direction of the liquid flow ejected by the nozzle 31 is controllable.

[0136] As Figure 5 shown, in some embodiments, the flow channel aperture of the second flow channel 3221 is larger than that of the first flow channel 3211.

[0137] Exemplarily, based on the flow channel aperture of the second flow channel 3221 being larger than that of the first flow channel 3211, and the flow channel aperture of the first flow channel 3211 being larger than the flow channel apertures of the first liquid outlet flow channel 313 and the second liquid outlet flow channel 314. Thus, after the liquid output by the host 10 passes through the converging action of the second flow channel 3221 and the first flow channel 3211, the liquid flows output by the first liquid outlet flow channel 313 and the second liquid outlet flow channel 314 have a better converging effect.

[0138] As Figure 5 shown, optionally, the first flow channel 3211 formed by the connecting rod 321 is at least two. Among them, at least one first flow channel 3211 communicates with the first liquid outlet flow channel 313 and the second flow channel 3221, and at least one first flow channel 3211 communicates with the second liquid outlet flow channel 314 and the second flow channel 3221.

[0139] By independently providing corresponding first flow channels 3211 for the first liquid outlet flow channel 313 and the second liquid outlet flow channel 314, and using the respective first flow channels 3211 to provide liquid flow to the corresponding first liquid outlet flow channel 313 and the second liquid outlet flow channel 314, the liquid flows of the first liquid outlet flow channel 313 and the second liquid outlet flow channel 314 can have stronger stability.

[0140] As Figure 5 shown, in some embodiments, the flow channel aperture of the first flow channel 3211 on the side close to the nozzle rod 322 is larger than the flow channel aperture of the first flow channel 3211 on the side close to the nozzle 31, so that the first flow channel 3211 has a stronger converging effect on the liquid flow.
