Description

Technical Field

[0001] The utility model relates to the field of tooth cleaning, in particular to a flushing integrated nozzle and a tooth cleaning device. Background Art

[0002] With the improvement of living standards, people's awareness of oral care has gradually increased, and the oral cleaning tools on the market have become more and more diverse. Among them, the water flosser has become one of the essential small appliances in the home as a substitute for traditional dental floss. Its basic working principle is to use the pump to draw water from the water tank and spray high-pressure pulse water through the nozzle hundreds or even thousands of times per minute to clean food residues and dental plaque in the gaps between teeth and massage gums, etc., to improve the oral environment.

[0003] Some water flossers are equipped with an integrated irrigating nozzle, but existing integrated irrigating nozzles are mostly a combination of a toothbrush and a nozzle, and users are still required to brush their teeth frequently when using them.

[0004] Chinese patent CN 219332049 U discloses a nozzle assembly of a multi-speed oral irrigator, which is connected by setting a connection relationship between a connecting column, a fan blade, a connecting plate and bristles, so that the water flow impacts the fan blade to drive the fan blade to rotate, so that the bristles can rotate, which is convenient for cleaning the inside of the oral cavity, and is convenient for improving the cleaning efficiency and practicability. However, on the connecting plate with bristles, water outlets are evenly provided, which leads to insufficient impact force of the water flow, and the water flow only plays a simple role in cleaning the bristles; on the other hand, the water flow has no guidance, and the impact on the fan blade is not enough, and it may not be able to overcome the friction of the bristles on the teeth to cause the bristles to rotate.

[0008] A nozzle body, wherein the nozzle body has a water inlet, and the nozzle body also has a swirl chamber connected to the water inlet, and the swirl chamber has an opening;

[0009] A rotating body, the rotating body is rotatably mounted in the cyclone chamber and forms a rotating surface at the opening, the rotating body is provided with fins along the circumferential direction of rotation, the fins receive the impact of the water flow from the water inlet and drive the rotating body to rotate; the rotating body alone or in cooperation with the opening forms a water flow flushing channel connected to the cyclone chamber;

[0010] A guide body, the guide body is arranged in the vortex chamber, and the guide body has a guide surface for guiding the water flow from the water inlet to impact the rotation of the fin;

[0011] Bristles are planted on the rotating surface.

[0012] Preferably, the water flushing channel is formed between the outer periphery of the rotating body and the inner diameter of the opening.

[0013] Preferably, the water flushing channel is formed through the rotating body, a channel opening at one end of the water flushing channel is located on the rotating surface, and the other end is connected to the vortex chamber.

[0014] Preferably, the rotating body is centrally arranged in the nozzle body; and the bristles are symmetrically arranged with respect to the center of the channel opening at one end of the water flushing channel.

[0015] Preferably, the rotating body is arranged in the swirl chamber through a rotating assembly, and the rotating assembly includes a rotating shaft and a rotating sleeve which are mutually sleeved and rotatable; the rotating shaft and the rotating sleeve are respectively arranged on the nozzle body and the rotating body.

[0016] Preferably, a first flow channel connected to the vortex chamber is formed between the rotating sleeve and the bottom of the nozzle body, a second flow channel is formed between the rotating sleeve and the rotating shaft, and the top of the rotating sleeve has a third flow channel connected to the channel opening; the first flow channel, the second flow channel and the third flow channel are connected to form the water flushing channel.

[0017] Preferably, the nozzle body includes a main body seat and a top cover, the swirl chamber is formed in the main body seat, the water inlet is arranged on the main body seat, the main body seat has a main body seat opening, the top cover has a top cover opening, the top cover is installed on the main body seat, and the main body seat opening and the top cover opening overlap to form the opening.

[0018] Preferably, the guide body is an arcuate guide section formed in the vortex chamber, and the end of the arcuate guide section has a chamfer; the guide surface is implemented as a first guide surface formed at the chamfer and facing the water inlet, and a second guide surface of the arcuate guide section facing the side of the vortex chamber; the end angles of the first guide surface and the second guide surface are directed toward the fin.

[0019] Preferably, the nozzle body is further provided with a limiting protrusion, the limiting protrusion is located at least on two sides of the bristles, and the area between the limiting protrusions is defined as a cleaning area for the bristles.

[0020] The above technical solutions alone or in combination show the following beneficial effects:

[0021] A rotating body that can be driven by water flow is arranged in the nozzle body, and bristles are planted on the rotating surface of the rotating body. A guide body is further arranged to guide the maximum impact kinetic energy of the water flow to the rotating body, so that the rotation of the rotating body is sufficient to overcome the brushing friction resistance of the bristles; automatic flushing without a power source can be better achieved, and an integrated flushing effect is formed, thereby achieving a better cleaning effect.

[0022] A water flushing channel is formed between the outer periphery of the rotating body and the inner diameter of the opening of the nozzle body, forming an effect of flushing the middle area all around, and the water flow is evenly formed around the bristles.

[0023] The rotating body can also have a water flushing channel, and the water can be discharged from the channel and the surrounding gaps at the same time. The middle area can be used for both brushing and flushing, which improves the cleaning efficiency of the oral cavity and the bristles themselves, and can also play an automatic cleaning role for the bristles.

[0024] The central arrangement of the rotating body can make the overall external structure symmetrical and more suitable for users with different usage habits; the existing incoming flow hitting the rotating body in the center has little rotation effect, so a guide body is provided to deflect the incoming flow and drive the rotating body obliquely.

[0025] The rotating body is installed through the rotating structure of the rotating sleeve and the rotating shaft, thereby reducing the probability of the rotating body slightly deviating and hitting the surrounding structure, and facilitating smooth rotation.

[0026] The guide body is an arc-shaped guide section formed in the vortex chamber. The structure of the arc-shaped guide section itself is also an arc-shaped guide structure and will not collide with the water flow. The water flow structure itself is relatively stable, and the end of the arc-shaped guide section forms a chamfer, and the position of the chamfer just faces the water inlet. The first guide surface is formed at the chamfer and faces the water inlet, that is, after the water flows in from the water inlet, it is directly guided to the fins by the guide surface, thereby acting on the rotation of the rotating body with greater kinetic energy reservation; and the arc-shaped guide section faces the vortex chamber to form a second guide surface, which guides the vortex in the vortex chamber to the fins again.

[0027] The limit protrusion is set, and the structural height of the limit protrusion is close to the height of the bristles to ensure that the rotating body can continue to rotate when the user is brushing, and the limit protrusion is against the tooth surface when in use. When the rotating body rotates driven by the water flow, there will be a slight lifting action. If the bristles are slightly shorter, they will just touch the tooth surface when lifting, and the bottom of the rotating body will not touch the bottom of the swirl chamber, and it can still keep rotating; if the bristles are slightly longer, because of the sharpened wire treatment at the front end of the bristle bundle and the flexibility of the bristle bundle itself, it will deform to a certain extent when touching the tooth surface, so that the tooth surface will not press the rotating body to the bottom of the swirl chamber, causing the rotating body to be unable to rotate.

[0028] The limiting protrusions are made of soft rubber, providing a more comfortable and safe experience.

[0029] In order to solve the second purpose, the utility model provides a tooth cleaning device, characterized in that it comprises a tooth cleaning device body and the integrated flushing nozzle; the tooth cleaning device body at least has a water spray component, and the water inlet of the integrated flushing nozzle is connected to the water spray component.

[0030] The beneficial effects of adopting the above technical solution are:

[0031] The tooth cleaning device can be a water flosser or other device with water supply capability. After the nozzle is installed on the main body of the tooth cleaning device, the water flow itself can pass through the nozzle body and the guide body to guide the maximum impact kinetic energy of the water flow to the rotating body, so that the rotation of the rotating body is sufficient to overcome the brushing friction resistance of the bristles; automatic flushing without a power source is achieved, and an integrated flushing effect is formed, thereby achieving a better cleaning effect.

[0044] Embodiment 1:

[0045] See also Figures 1 to 8 The present embodiment provides a flushing integrated nozzle, comprising a nozzle body 1, a rotating body 2, a guide body 4 and bristles 3. The nozzle body 1 has a water inlet 10, and the nozzle body 1 also has a swirl cavity (i.e., the internal cavity of the nozzle body 1) connected to the water inlet 10, and the swirl cavity has an opening; the rotating body 2 is rotatably assembled in the swirl cavity and forms a rotating surface 22 at the opening, and the rotating body 2 is provided with fins 21 along the rotation circumference, and the fins 21 receive the impact of the water flow from the water inlet 10 and drive the rotating body 2 to rotate; the rotating body 2 forms a water flow flushing channel connected to the swirl cavity alone or in cooperation with the opening; the guide body 4 is arranged in the swirl cavity, and the guide body 4 has a guide surface for guiding the water flow from the water inlet 10 to impact the rotation of the fins 21; the bristles 3 are planted on the rotating surface 22. In this embodiment, a rotating body 2 that can be driven by water flow is arranged in the nozzle body 1, and bristles are planted on the rotating surface 22 of the rotating body 2. A guide body 4 is further arranged to guide the maximum impact kinetic energy of the water flow to the rotating body 2, so that the rotation of the rotating body 2 is sufficient to overcome the brushing friction resistance of the bristles 3; automatic flushing without a power source can be better achieved, and an integrated flushing effect can be formed, thereby achieving a better cleaning effect.

[0046] The above is necessary to achieve the technical purpose of this embodiment, and is further described in detail below with reference to the accompanying drawings:

[0047] In this embodiment, the rotating body 2 is pushed by the water flow through its own fins 21, so as to rotate in the vortex chamber of the nozzle body 1, and the bristles 3 on its rotating surface 22 also rotate accordingly, thereby achieving an automatic brushing effect.

[0048] Furthermore, water washing and cleaning are carried out by flushing the channel with water flow, thereby achieving integrated flushing.

[0049] In this embodiment, the water flushing channel can be formed by the rotating body 2 itself or in cooperation with the nozzle body 1. Specifically, the water flushing channel 20a is formed between the outer periphery of the rotating body 2 and the inner diameter of the opening. Further, the water flushing channel 20b can also be formed through the rotating body 2, and the channel opening at one end of the water flushing channel 20b is located on the rotating surface 22, and the other end is connected to the swirl chamber.

[0050] The above two water flow channel forms can be implemented in this embodiment either one or both, and they are not limited here.

[0051] The rotating body 2 is arranged in the center of the nozzle body 1; when the channel opening at one end of the water flow flushing channel 20b is located on the rotating surface 22 and the other end is connected to the swirl chamber, the bristles 3 are arranged symmetrically with respect to the channel opening at one end of the water flow flushing channel 20b. Preferably, the rotating body 2 and the nozzle body 1 both adopt a cylindrical structure. The symmetrical layout of the rotating body 2 can also be more suitable for users with different usage habits, whether they use it with the forehand or the backhand.

[0052] The rotating body 2 can be arranged in the swirl chamber without any structure, and the purpose of being impacted by the water flow can be basically achieved. However, even if the rotating body 2 and the nozzle body 1 are both circular structures, there is still a phenomenon of micro-deviation and impact. As a preferred implementation of this embodiment, the rotating body 2 is arranged in the swirl chamber through a rotating component, and the rotating component includes a rotating shaft 5 and a rotating sleeve 6 that are mutually sleeved and rotatable; the rotating shaft 5 and the rotating sleeve 6 are respectively arranged on the nozzle body 1 and the rotating body 2.

[0053] Specifically, in this embodiment, the rotating shaft 5 is provided on the nozzle body 1, and the rotating sleeve 6 is provided on the rotating body 2, and can subsequently cooperate with the rotating body 2 to form a water flow flushing channel 20b. It should be noted that the "rotating shaft 5+rotating sleeve 6" is intended to provide a specific rotating installation structure, and other structures that can be equivalent to this should also be included in this embodiment.

[0054] Please combine Figure 3 , Figure 5 and Figure 6 When the water flushing channel 20b is formed on the rotating body 2, a first flow channel 201 connected to the swirl chamber is formed between the rotating sleeve 6 and the bottom of the nozzle body 1, a second flow channel 202 is formed between the rotating sleeve 6 and the rotating shaft 5, and a third flow channel 203 connected to the channel opening is provided on the top of the rotating sleeve 6; the first flow channel 201, the second flow channel 202 and the third flow channel 203 are connected to form the water flushing channel 20b. The water flow is guided from the water inlet 10 to the impact fin 21 and then fills the swirl chamber, then enters the second flow channel 202 from the first flow channel 201, and finally flows out from the third flow channel 203.

[0055] At the same time, please combine Figure 2 , Figure 4 and Figure 5 When the gap between the rotating body 2 and the opening of the nozzle body 1 also forms a water flushing channel 20a, after the water flows fully through the vortex cavity, a part of the water flow can also flow out through this place.

[0056] Please combine Figure 2 and Figure 5 The nozzle body 1 is a main structure, which includes a main body seat 11 and a top cover 12. The purpose of assembling and installing the two is to facilitate the molding of the guide body 4 and the installation of the rotating body 2. Among them, the swirl chamber is formed in the main body seat 11, the water inlet 10 is arranged on the main body seat 11, the main body seat 11 has a main body seat opening, the top cover 12 has a top cover opening 120, the top cover 12 is installed on the main body seat 11, and the main body seat opening and the top cover opening 120 overlap to form the opening of the nozzle body 1. It should be noted that in terms of size design, at least the diameter of the top cover opening 120 should be smaller than the rotation diameter of the multiple enclosing fins 21 of the rotating body 2 to prevent the rotating body 2 from falling off the nozzle body 1. When there are multiple fins 21, even if the fins 21 are against the top cover opening 120, a gap is formed between the rotating body 2 and the top cover 12, and a flow channel is formed between the fins 21, and the water flows from the flow channel to the gap between the rotating body 2 and the top cover 12.

[0057] The guide body 4 is arranged in the vortex chamber to avoid disturbing the flow. Figure 8 The guide body 4 is an arc-shaped guide section formed in the vortex chamber, and the end of the arc-shaped guide section has a chamfer 41. The guide surface of this embodiment is implemented as a first guide surface 410 formed at the chamfer 41 and facing the water inlet 10, and a second guide surface 42 of the arc-shaped guide section facing the side of the vortex chamber; the end angles of the first guide surface 410 and the second guide surface 42 are directed to the fin 21.

[0058] Further, please combine Figure 1 , Figure 2 and Figure 8 The arc-shaped guide section is attached to the inner wall of the nozzle body 1, and the side facing the swirl chamber is an arc-shaped surface, and the end angle of the arc-shaped surface is preferably facing the fin 21, that is, the arc-shaped surface is defined as the second guide surface 42. Specifically, the water flow of the water inlet 10 is first guided by the first guide surface 410 to impact the fin 21, and a swirl is formed in the swirl chamber. When the swirl naturally flows on the arc-shaped surface of the arc-shaped guide section (that is, the second guide surface 42), it is guided to the fin 21 again, thereby realizing double guidance.

[0059] Further, please combine Figure 6 and Figure 7, the nozzle body 1 is also provided with a limiting protrusion 121, which is located on at least two sides of the bristles 3, and the area between the limiting protrusions 121 is defined as the cleaning area of ​​the bristles 3. The height of the limiting protrusion 121 should not be less than the height of the bristles 3. The limiting protrusion 121 is provided, and the structural height of the limiting protrusion 121 is close to the height of the bristles 3 to ensure that the rotating body 2 can continue to rotate when the user is flushing, and the limiting protrusion 121 is against the tooth surface (tooth surface) when in use. When the rotating body 2 rotates driven by the water flow, there will be a slight lifting action. If the bristles 3 are slightly shorter, they will just touch the tooth surface when lifting, and the bottom of the rotating body 2 will not contact the bottom of the swirl chamber, and it can still keep rotating; if the bristles 3 are slightly longer, because of the sharpened wire treatment at the front end of the bristle bundle and the flexibility of the bristle bundle itself, it will deform to a certain extent when touching the tooth surface, so that the tooth surface will not press the rotating body 2 to the bottom of the swirl chamber, causing the rotating body 2 to be unable to rotate.

[0060] The above technical solutions alone or in combination show the following beneficial effects:

[0061] A rotating body 2 that can be driven by water flow is arranged in the nozzle body 1, and bristles are planted on the rotating surface 22 of the rotating body 2. A guide body 4 is further arranged to guide the maximum impact kinetic energy of the water flow to the rotating body 2, so that the rotation of the rotating body 2 is sufficient to overcome the brushing friction resistance of the bristles 3; automatic flushing without a power source can be better achieved, and an integrated flushing effect can be formed, thereby achieving a better cleaning effect.

[0062] A water flushing channel is formed between the outer periphery of the rotating body 2 and the inner diameter of the opening of the nozzle body 1, so that the middle area is flushed all around, and the water flow is evenly formed around the bristles 3.

[0063] The rotating body 2 may also be provided with a water flushing channel, and water may be discharged from the channel and the surrounding gaps at the same time, so that the middle area can be used for both brushing and flushing, thereby improving the cleaning efficiency of the oral cavity and the bristles 3 themselves, and also achieving an automatic cleaning effect on the bristles 3 .

[0064] The central arrangement of the rotating body 2 can make the overall external structure symmetrical and more suitable for users with different usage habits (left-handedness, angle habits, etc.); the existing incoming flow hitting the rotating body 2 in the center has little rotation effect, so the guide body 4 is set to deflect the incoming flow and drive the rotating body 2 obliquely.

[0065] The rotating body 2 is installed by the rotating structure of the rotating sleeve 6 and the rotating shaft 5, thereby reducing the probability of the rotating body 2 slightly deviating and colliding with the surrounding structure, and facilitating smooth rotation.

[0066] The guide body 4 is an arc-shaped guide section formed in the vortex chamber. The structure of the arc-shaped guide section itself is also an arc-shaped guide structure and will not collide with the water flow. The water flow structure itself is relatively stable, and a chamfer 41 is formed at the end of the arc-shaped guide section. The position of the chamfer 41 just faces the water inlet 10. The first guide surface is formed at the chamfer 41 and faces the water inlet 10. That is, after the water flows in from the water inlet 10, it is directly guided to the fin 21 by the guide surface, thereby acting on the rotation of the rotating body 2 with greater kinetic energy retention.

[0067] The limiting protrusion 121 is provided, and the structural height of the limiting protrusion 121 is close to the height of the bristles 3 to ensure that the rotating body 2 can continue to rotate when the user is flushing, and the limiting protrusion 121 is pressed against the tooth surface when in use. When the rotating body 2 rotates driven by the water flow, there will be a slight lifting action. If the bristles 3 are slightly shorter, they will just touch the tooth surface when lifting, and the bottom of the rotating body 2 will not touch the bottom of the swirl chamber, and it can still keep rotating; if the bristles 3 are slightly longer, because of the sharpened wire treatment at the front end of the bristle bundle and the flexibility of the bristle bundle itself, it will be deformed to a certain extent when touching the tooth surface, so that the tooth surface will not press the rotating body 2 to the bottom of the swirl chamber, causing the rotating body 2 to be unable to rotate.

[0068] The limiting protrusion 121 is made of soft rubber, which provides a more comfortable and safe experience.

[0069] Embodiment 2:

[0070] See also Figures 1 to 8 This embodiment provides a tooth cleaning device, including a tooth cleaning device body and an integrated flushing nozzle; the tooth cleaning device body at least has a water spray component, and the water inlet 10 of the integrated flushing nozzle is connected to the water spray component. The tooth cleaning device can be a water flosser or other cleaning device with water supply capability.

[0071] This embodiment is described by taking a water flosser as an example, but this embodiment does not elaborate on the principle structure of the water flosser. It is known that the water flosser includes a body and a nozzle; and in this embodiment, the nozzle of embodiment 1 can be replaced with the nozzle of the water flosser. It is common to install a spray rod on the water pump outlet of the water flosser, and the spray rod can be replaced with various types of nozzles by threaded connection, and the nozzle in this embodiment can also be the same.

[0072] A threaded section is formed at the water inlet 10 of the nozzle body 1 (body seat 11) to facilitate installation with the spray rod of the oral irrigator.

[0073] Furthermore, the integrated flushing nozzle comprises a nozzle body 1, a rotating body 2, a guide body 4 and bristles 3. The nozzle body 1 has a water inlet 10, and the nozzle body 1 also has a swirl chamber connected to the water inlet 10, and the swirl chamber has an opening; the rotating body 2 is rotatably assembled in the swirl chamber and forms a rotating surface 22 at the opening, and the rotating body 2 is provided with fins 21 along the rotation circumference, and the fins 21 receive the impact of the water flow from the water inlet 10 and drive the rotating body 2 to rotate; the rotating body 2 alone or in cooperation with the opening forms a water flow flushing channel connected to the swirl chamber; the guide body 4 is arranged in the swirl chamber, and the guide body 4 has a guide surface that guides the water flow from the water inlet 10 to impact the rotation of the fins 21; the bristles 3 are planted on the rotating surface 22.

[0074] In this embodiment, the rotating body 2 is pushed by the water flow through its own fins 21, so as to rotate in the vortex chamber of the nozzle body 1, and the bristles 3 on its rotating surface 22 also rotate accordingly, thereby achieving an automatic brushing effect.

[0075] Furthermore, the water flow is used to wash and clean the teeth, thereby realizing flushing and cleaning. The high-frequency pulse water flow of the water flosser can achieve the effect of cleaning teeth.

[0076] In this embodiment, the water flushing channel can be formed by the rotating body 2 itself or in cooperation with the nozzle body 1. Specifically, the water flushing channel 20a is formed between the outer periphery of the rotating body 2 and the inner diameter of the opening. Further, the water flushing channel 20b can also be formed through the rotating body 2, and the channel opening at one end of the water flushing channel 20b is located on the rotating surface 22, and the other end is connected to the swirl chamber.

[0077] The above two water flow channel forms can be implemented in this embodiment either one or both, and they are not limited here.

[0078] The rotating body 2 is arranged in the center of the nozzle body 1; when the channel opening at one end of the water flow flushing channel 20b is located on the rotating surface 22 and the other end is connected to the swirl chamber, the bristles 3 are arranged symmetrically with respect to the channel opening at one end of the water flow flushing channel 20b. Preferably, the rotating body 2 and the nozzle body 1 both adopt a cylindrical structure. The symmetrical layout of the rotating body 2 can also be more suitable for users with different usage habits, whether they use it with the forehand or the backhand.

[0079] The rotating body 2 can be arranged in the swirl chamber without any structure, and the purpose of being impacted by the water flow can be basically achieved. However, even if the rotating body 2 and the nozzle body 1 are both circular structures, there is still a phenomenon of micro-deviation and impact. As a preferred implementation of this embodiment, the rotating body 2 is arranged in the swirl chamber through a rotating component, and the rotating component includes a rotating shaft 5 and a rotating sleeve 6 that are mutually sleeved and rotatable; the rotating shaft 5 and the rotating sleeve 6 are respectively arranged on the nozzle body 1 and the rotating body 2.

[0080] Specifically, in this embodiment, the rotating shaft 5 is provided on the nozzle body 1, and the rotating sleeve 6 is provided on the rotating body 2, and can subsequently cooperate with the rotating body 2 to form a water flow flushing channel 20b. It should be noted that the "rotating shaft 5+rotating sleeve 6" is intended to provide a specific rotating installation structure, and other structures that can be equivalent to this should also be included in this embodiment.

[0081] Please combine Figure 3 , Figure 5 and Figure 6 When the water flushing channel 20b is formed on the rotating body 2, a first flow channel 201 connected to the swirl chamber is formed between the rotating sleeve 6 and the bottom of the nozzle body 1, a second flow channel 202 is formed between the rotating sleeve 6 and the rotating shaft 5, and a third flow channel 203 connected to the channel opening is provided on the top of the rotating sleeve 6; the first flow channel 201, the second flow channel 202 and the third flow channel 203 are connected to form the water flushing channel 20b. The water flow is guided from the water inlet 10 to the impact fin 21 and then fills the swirl chamber, then enters the second flow channel 202 from the first flow channel 201, and finally flows out from the third flow channel 203.

[0082] At the same time, please combine Figure 2 , Figure 4 and Figure 5 When the gap between the rotating body 2 and the opening of the nozzle body 1 also forms a water flushing channel 20a, after the water flows fully through the vortex cavity, a part of the water flow can also flow out through this place.

[0083] Please combine Figure 2 and Figure 5 The nozzle body 1 is a main structure, which includes a main body seat 11 and a top cover 12. The purpose of assembling and installing the two is to facilitate the molding of the guide body 4 and the installation of the rotating body 2. Among them, the swirl chamber is formed in the main body seat 11, the water inlet 10 is arranged on the main body seat 11, the main body seat 11 has a main body seat opening, the top cover 12 has a top cover opening 120, the top cover 12 is installed on the main body seat 11, and the main body seat opening and the top cover opening 120 overlap to form the opening of the main body seat 1. It should be noted that in terms of size design, at least the diameter of the top cover opening 120 should be smaller than the rotation diameter of the multiple enclosing fins 21 of the rotating body 2 to prevent the rotating body 2 from falling off the nozzle body 1. When there are multiple fins 21, even if the fins 21 are against the top cover opening 120, a gap is formed between the rotating body 2 and the top cover 12, and a flow channel is formed between the fins 21, and the water flows from the flow channel to the gap between the rotating body 2 and the top cover 12.

[0084] The guide body 4 is arranged in the vortex chamber to avoid disturbing the flow. Figure 8The guide body 4 is an arc-shaped guide section formed in the vortex chamber, and the end of the arc-shaped guide section has a chamfer 41. The guide surface of this embodiment is implemented as a first guide surface 410 formed at the chamfer 41 and facing the water inlet 10, and a second guide surface 42 of the arc-shaped guide section facing the vortex chamber; the end angles of the first guide surface 410 and the second guide surface 42 are directed to the fin 21.

[0085] Further, please combine Figure 1 , Figure 2 and Figure 8 The arc-shaped guide section is attached to the inner wall of the nozzle body 1, and the side facing the swirl chamber is an arc-shaped surface, and the end angle of the arc-shaped surface is preferably facing the fin 21, that is, the arc-shaped surface is defined as the second guide surface 42. Specifically, the water flow of the water inlet 10 is first guided by the first guide surface 410 to impact the fin 21, and a swirl is formed in the swirl chamber. When the swirl naturally flows on the arc-shaped surface of the arc-shaped guide section (that is, the second guide surface 42), it is guided to the fin 21 again, thereby realizing double guidance.

[0086] Further, please combine Figure 6 and Figure 7 , the nozzle body 1 is also provided with a limiting protrusion 121, which is located on at least two sides of the bristles 3, and the area between the limiting protrusions 121 is defined as the cleaning area of ​​the bristles 3. The height of the limiting protrusion 121 should not be less than the height of the bristles 3. The limiting protrusion 121 is provided, and the structural height of the limiting protrusion 121 is close to the height of the bristles 3 to ensure that the rotating body 2 can continue to rotate when the user is flushing, and the limiting protrusion 121 is against the tooth surface (tooth surface) when in use. When the rotating body 2 rotates driven by the water flow, there will be a slight lifting action. If the bristles 3 are slightly shorter, they will just touch the tooth surface when lifting, and the bottom of the rotating body 2 will not contact the bottom of the swirl chamber, and it can still keep rotating; if the bristles 3 are slightly longer, because of the sharpened wire treatment at the front end of the bristle bundle and the flexibility of the bristle bundle itself, it will deform to a certain extent when touching the tooth surface, so that the tooth surface will not press the rotating body 2 to the bottom of the swirl chamber, causing the rotating body 2 to be unable to rotate.

[0087] The beneficial effects of adopting the above technical solution are:

[0088] The tooth cleaning device can be a water flosser or other device with water supply capability. After the nozzle is installed on the main body of the tooth cleaning device, the water flow itself can pass through the nozzle body 1 and the guide body 4 to guide the maximum impact kinetic energy of the water flow to the rotating body 2, so that the rotation of the rotating body 2 is sufficient to overcome the brushing friction resistance of the bristles 3; automatic flushing without a power source is achieved, and an integrated flushing effect is formed, thereby achieving a better cleaning effect.

[0089] It should be understood by those skilled in the art that the embodiments of the present invention described above are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Without departing from the principles, the embodiments of the present invention may be deformed or modified in any way.
