Referring to fig. 1 to 4, the dental irrigator 100 includes a main body 10 and a handpiece 20. The body 10 extends in a first direction. The fuselage 10 is for gripping. The handpiece 20 includes a first housing 21 and an infusion tube 22, the first housing 21 having formed thereinThe first cavity 211, at least part of the infusion tube 22 is disposed in the first cavity 211, the first housing 21 includes a first end 212 and a second end 213 opposite to each other, the first end 212 is connected to one end of the body 10 in the first direction, the second end 213 is provided with a connection hole 214 corresponding to the infusion tube 22, and the connection hole 214 is used for a nozzle 60 to pass through and communicate with the infusion tube 22. Wherein the first housing 21 is provided with a through hole 23 and the through hole 23 extends along the second direction, the through hole 23 is not communicated with the first cavity 211, and the area of at least one of the two ends of the through hole 23 is larger than 12mm ² The second direction is perpendicular to the first direction.

In the dental irrigator 100 of the embodiment of the application, by arranging the through hole 23, when the head 20 needs to be irrigated, if the impact force of the faucet is large, the water flow sprayed by the faucet can be aligned to the through hole 23, part of the water flow enters the through hole 23, the through hole 23 can play a certain buffering role, a user can clean the head 20 by utilizing part of the water flow impacting to the solid part of the head 20 and the buffered water flow entering the through hole 23, and the water flow on the impact side and the outflow side of the straight impact can be utilized to flush the whole dental irrigator 100.

Specifically, the mouthwash 100 can pump out the clear or mouthwash to form a pulsed water flow that impinges on the teeth and crevices of the user, thereby effecting cleaning of the teeth and mouth of the user. It can be appreciated that the dental irrigator 100 of the present embodiment may be exchanged for a full body water wash, and after the user finishes using the dental irrigator 100 may be aligned to a faucet, so that the dental irrigator 100 may be kept clean, and dirt accumulated on the machine body 10 and the machine head 20 is avoided. The tooth washing device 100 comprises a machine body 10 and a machine head 20, wherein the machine head 20 is provided with a through hole 23, so that water flow can be aligned to the through hole 23 by a user, the problem that the water flow is splashed when impacting the machine head 20 can be avoided, and the water flow can directly penetrate through the through hole 23 to wash the machine body 10 from two sides of the machine body 10.

In the embodiment, the first direction is the length direction of the body 10, the handpiece 20 and the body 10 may be disposed along the first direction, such that the first end 212 of the first housing 21 is connected to the body 10, the second end 213 may be remote from the body 10, the second end 213 may be provided with a connection hole 214, and the nozzle 60 may pass through the connection hole 214 and communicate with the infusion tube 22. In this way, a user can hold the body 10 and align the second end 213 with the nozzle 60 in his mouth. The solution may be ejected through the tubing 22 and out the nozzle 60 to clean the user's mouth.

It will be appreciated that in the present embodiment, the first direction is the longitudinal direction of the main body 10, that is, the longitudinal direction of the tooth-rinsing device 100, the second direction is the thickness direction of the tooth-rinsing device 100, the third direction is the width direction of the tooth-rinsing device 100, and the three directions are designed to be perpendicular to each other. The handpiece 20 and the body 10 are connected in a first direction, and the body 10 is connected to the first end 212 such that the nozzle 60 provided at the second end 213 can be aligned in the first direction with the mouth of the user. The through hole 23 of the first housing 21 may extend through the first shell in the second direction and the through hole 23 is non-communicating with the first cavity 211 such that, when the dental impactor 100 is being rinsed with a water flow, the water flow passes through the through hole 23 and may flow along the outer surface of the dental impactor 100 without entering the first cavity 211.

Further, at least one of the two ends of the through hole 23 has an area larger than 12mm ² So that the water flow can pass through the through hole 23 in an area of more than 12mm during the process of flushing the dental appliance 100 by using the water tap ² Enters the through hole 23 and flows out from the other side of the through hole 23, so that the water flow can flush the entire tooth irrigator 100. In the embodiment of the present application, the area of both ends of the through hole 23 may be larger than 12mm ² In this case, the areas of both ends passing through may be equal or different. Of course, it is also possible to have one of the through holes 23 greater than 12mm ² Another is less than 12mm ² Thus, the area can be larger than 12mm ² Is aligned with the tap so that the water flow sprayed from the tap can smoothly enter the through hole 23, and since the area of the other end of the through hole 23 is smaller than 12mm ² So that the water flow can flow out from the other side of the through hole 23 and along the outer surface of the dental impactor 100, avoiding that the water flow directly through the through hole 23 does not flow along the outer surface of the dental impactor 100.

Referring to fig. 3, in some embodiments, the infusion tube 22 in the first cavity 211 extends in a first direction, and the infusion tube 22 in the first cavity 211 is spaced apart from the through hole 23 in a third direction, which is perpendicular to the first direction and the second direction, respectively.

In this way, the infusion tube 22 extends in the first direction so that the infusion tube 22 can draw out the solution at the bottom of the water tank 50, and the infusion tube 22 can be spaced from the through hole 23 in the third direction, so that other elements in the first cavity 211 are prevented from affecting the normal operation of the infusion tube 22.

Further, referring to fig. 3, in some embodiments, the handpiece 20 further includes a filling pipe 24, at least a portion of the filling pipe 24 is located in the first cavity 211, a filling hole 215 communicating with the filling pipe 24 is formed on an outer surface of the first housing 21, and the filling pipe 24 and the filling pipe 22 are located at two sides of the through hole 23 in a third direction, and the third direction is perpendicular to the first direction and the second direction respectively.

In this way, the infusion tube 24 and the infusion tube 22 are respectively located at two sides of the through hole 23, so that the through hole 23 can separate the infusion tube 24 from the infusion tube 22, and the interaction of the infusion tube 24 and the infusion tube 22 is avoided.

Specifically, the filling pipe 24 and the infusion pipe 22 may be disposed at intervals in the width direction of the tooth punch 100, and the through holes 23 may be disposed at the middle portions of the filling pipe 24 and the infusion pipe 22 to separate the filling pipe 24 and the infusion pipe 22 from each other, avoiding the two from affecting each other. The liquid filling pipe 24 may be connected to the liquid filling hole 215, and clean water or mouthwash may be filled into the water tank 50 through the liquid filling hole 215 and the liquid filling pipe 24. The nozzle 60 may pass through the connection hole 214 and be connected with the infusion tube 22 so that the solution in the water tank 50 may be sprayed to the outside through the infusion tube 22 and the nozzle 60 in sequence to clean the oral cavity of the user.

Referring to fig. 3, in some embodiments, the body 10 includes a second housing 11 and a pump assembly 12, the second housing 11 is connected to the first housing 21, a second cavity 111 is formed in the second housing 11, the second cavity 111 is in communication with the first cavity 211, at least part of the pump assembly 12 is located in the second cavity 111, the pump assembly 12 is connected to the infusion tube 22 to pump liquid into the infusion tube 22, the pump assembly 12 is spaced from the infusion tube 24, and in a third direction, the pump assembly 12 and the infusion tube 24 are located on two sides of the through hole 23, respectively.

In this manner, the pump assembly 12 provides the driving force to pump fluid to the tube 22, and thus the solution in the reservoir 50 is ejected through the tube 22 and nozzle 60 with sufficient force to clean the user's mouth and teeth. Meanwhile, the through hole 23 can separate the liquid pumping assembly 12 from the liquid injection pipe 24 in the third direction, so that the liquid injection pipe 24 and the liquid pumping assembly 12 are prevented from being affected mutually.

Specifically, the pump assembly 12 may be coupled to the infusion tube 22 and pump fluid to the infusion tube 22 so that the solution may be ejected from the nozzle 60 with a certain impact force to provide better cleaning of the teeth and crevices of the user. In addition, in the third direction, the pump liquid component 12 and the liquid injection pipe 24 are respectively located at two sides of the through hole 23, so that the mutual influence between the pump liquid component 12 and the liquid injection pipe 24 is avoided, and the influence on the normal operation of the liquid injection pipe 24 due to the heat and vibration generated by the pump liquid component 12 transferred to the liquid injection pipe 24 is avoided.

Referring to fig. 1, in some embodiments, the first housing 21 has a maximum dimension a in the second direction, the first housing 21 has a maximum dimension b in the third direction, a is smaller than b, and the third direction is perpendicular to the first direction and the second direction, respectively.

In this way, the infusion tube 24 and the infusion tube 22 may be arranged in a third direction, so that the handpiece 20 may be reduced in size in the first direction to thin the handpiece 20 of the dental irrigator 100, so that the entire dental irrigator 100 is more compact and lightweight.

Further, referring to fig. 5 and 6, in some embodiments, the first housing 21 is in a shape of a revolving body, and an axis of the revolving body extends along a second direction, the first housing 21 includes a first end face 216, a second end face 217, and a revolving face 218, the first end face 216 and the second end face 217 are opposite in the second direction, the revolving face 218 is disposed between the first end face 216 and the second end face 217 and connects the first end face 216 and the second end face 217, respectively, and the through hole 23 penetrates the first end face 216 and the second end face 217 along the second direction.

Thus, upon rinsing the dental rinse 100, either the first end surface 216 or the second end surface 217 may be aligned such that water flow may pass through the through-hole 23 and flow from both the first end surface 216 and the second end surface 217 toward the body 10 to clean the body 10. While the first end 212 and the second end 213 may be formed on the swivel surface 218 such that the swivel surface 218 may be coupled to the body 10, while the first housing 21 is in the shape of a swivel such that the tooth punch 100 is aesthetically pleasing, while allowing greater space for the first cavity 211 to carry more components.

Specifically, the first housing 21 is in a shape of a revolution body, a is a length of the revolution body in an axial direction, b is a diameter length of the revolution body, and a is smaller than b so that the first housing 21 is in a shape of a cake, so that the machine head 20 is lighter and thinner. The through-hole 23 extends through the first end surface 216 and the second end surface 217 in the second direction such that water flow from the first end surface 216 through the through-hole 23 to the second end surface 217 or from the second end surface 217 through the through-hole 23 to the first end surface 216 during cleaning of the dental appliance 100. In addition, the injection holes 215 and the connection holes 214 may be provided on the second end 213 of the rotation surface 218 such that the nozzles 60 and the injection holes 215 may be aligned on a side remote from the body 10.

In certain embodiments, the cross-sectional area of the through hole 23 on the first end face 216 is M, the area of the first end face 216 is S, 1:3. Gtoreq.M, S. Gtoreq.1:64; and/or the through hole 23 is a round hole, and the ratio of the radius of the first end surface 216 to the radius of the through hole 23 is greater than or equal to 1.5 and less than or equal to 8.

In this way, the ratio between the through hole 23 and the first end face 216 is defined, so that on one hand, water flow can smoothly pass through the through hole 23, water splashing is avoided, on the other hand, the excessive space affecting the first cavity 211 of the through hole 23 is avoided, and water flow which can not flow along the two end faces is avoided when the water flow directly passes through the through hole 23.

Specifically, the first housing 21 may be cylindrical, the through hole 23 is a circular hole, and the through hole 23 may penetrate through the first end face 216 and the second end face 217 along the second direction, and in such an embodiment, the first end face 216, the second end face 217 and the through hole 23 may ensure an area ratio of 1:3+_m:s+_1:64, and simultaneously satisfy that a ratio of a radius of the first end face 216 to a radius of the through hole 23 is 1.5+_8 or more. Of course, in some embodiments, the through holes 23 may not be circular holes, and only the areas of the first end surface 216 and the through holes 23 need be limited, i.e., 1:3. Gtoreq.M: S. Gtoreq.1:64. In other embodiments, the through-hole 23 is a circular hole and defines only a ratio of the radius of the first end surface 216 to the radius of the through-hole 23 of 1.5 to 8.

Illustratively, the ratio M: S of the cross-sectional area of the through-hole 23 on the first end face 216 to the area of the first end face 216 is desirably 1:64 or greater and 1:3 or less. For example, M: S may be 1:64, 1:32, 1:16, 1:8, 1:4, 1:3. When the through hole 23 is a circular hole, the ratio of the radius of the first end surface 216 to the radius of the through hole 23 is 1.5 or less and 8 or less. For example, the ratio of the radius of the first end surface 216 to the radius of the through hole 23 may be 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8.

In certain embodiments, the first end face 216 and the second end face 217 have a peripheral diameter of 45mm to 70mm. In this way, the first housing 21 is made to be of a moderate size, avoiding the problem of heavy head and light foot, and also ensuring that the first cavity 211 has enough space to accommodate the components. At the same time, the handpiece 20 of the dental irrigator 100 of the present application can be made in various sizes to accommodate different people.

Illustratively, the outer peripheral diameters of the first end face 216 and the second end face 217 may be 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, so that the handpiece 20 may be designed in various sizes while being adapted to the size of the through hole 23, thereby satisfying the cross-sectional area ratio of the first end face 216 to the through hole 23.

Referring to fig. 1, in some embodiments, any cross section of the through hole 23 is circular, and the through hole 23 is disposed coaxially with the first housing 21.

Thus, the through hole 23 is a circular hole as a whole, so that the water flow of the through hole 23 is smoother when passing through the through hole 23, and meanwhile, the through hole 23 and the first shell 21 are kept in a similar shape and coaxially arranged, so that the design style of the whole machine head 20 is uniform, and the tooth washer 100 is more attractive.

In some embodiments, the cross-sectional area of the through-hole 23 gradually decreases from both ends of the through-hole 23 to the middle.

Thus, the cross-sectional area of the two ends of the through hole 23 is large, the very cross-sectional area of the middle part is small, so that water flow can easily enter the through hole 23 and contact the inner wall of the through hole 23, so that the water flow can flow out along the inner wall of the through hole 23 and flow along the outer surface of the machine head 20, and then the machine head 20 and the machine body 10 are flushed.

Referring to fig. 5 and 6, in some embodiments, the handpiece 20 includes a first end face 216 and a second end face 217 disposed opposite to each other, the through hole 23 penetrates the first end face 216 and the second end face 217 along a second direction, at least one of the first end face 216 and the second end face 217 includes a first portion 2161 and a second portion 2162, the first portion 2161 is located at an outer periphery of the second portion 2162, the first portion 2161 is recessed gradually inward from the direction of the outer periphery of the second portion 2162, the second portion 2162 is planar, the second portion 2162 is perpendicular to the second direction, the through hole 23 is located at the second portion 2162, and the through hole 23 is spaced apart from the outer periphery of the second portion 2162, and the first portion 2161 and the second portion 2162 form a recess 2163; or at least one of the first end face 216 and the second end face 217 is recessed gradually from the direction of the outer circumferential through hole 23 into the recess 2163.

In this way, at least one of the first end surface 216 and the second end surface 217 may form the concave portion 2163 that is concave inward, and when the tooth-rinsing device 100 is cleaned, the water flow may be aligned to the concave portion 2163, so that the water flow may enter the through hole 23 along the concave portion 2163, so as to avoid the problem that the water flow directly impacts the plane to cause splash.

It will be appreciated that the recess 2163 has a curvature such that less splashing is created when water flows contact the recess 2163, while the through-hole 23 may be located in the second portion 2162 such that water flowing into the recess 2163 may quickly enter the through-hole 23. The water flow can flow to the other side through the through-hole 23 so that the water flow can simultaneously rinse the dental irrigator 100 from both sides. In one example, the first end surface 216 has a recess 2163 formed therein, and a user aligns the faucet with the through-hole 23 of the first end surface 216, and water flow may impinge on the recess 2163 and flow from the first end surface 216 to the second end surface 217 through the through-hole 23. In another example, a recess 2163 is formed in the second end face 217, and a user aligns the faucet with the through-hole 23 of the second end face 217, and water flow may impinge on the recess 2163 and flow from the second end face 217 to the first end face 216 through the through-hole 23. In yet another example, the first end surface 216 and the second end surface 217 may have a recess 2163 formed thereon at the same time, and the user may choose to align the faucet with the through-hole 23 of the first end surface 216 or the second end surface 217, and the water flow may strike the recess 2163 and flow from one end surface to the other through the through-hole 23.

In certain embodiments, the depth of the recess 2163 is 2.5mm-8mm in the second direction. For example, in the second direction, the depth of the recess 2163 may be 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm. In this way, the depth of the recess 2163 is set within this range, so that the recess 2163 can receive the impact of the water flow, so as to avoid splashing of the water flow, and ensure that the first cavity 211 has enough space for accommodating the components.

Referring to fig. 7, in some embodiments, the dental impactor 100 includes a key 30 and a charging interface 40, with the key 30 and the charging interface 40 being located outside the recess 2163.

In this way, the user can control the on-off and mode switching of the dental irrigator 100 through the key 30, and can also wash the teeth of the dental irrigator 100 through the charging interface 40.

Referring to fig. 1 and 7, in some embodiments, the body 10 includes a second housing 11, and a key 30 and a charging port 40 provided on the second housing 11, and the dental caries device 100 further includes a water tank 50 slidably sleeved on the second housing 11 to slide between a first position and a second position relative to the second housing 11, the water tank 50 having a maximum volume when the water tank 50 is in the second position, the water tank 50 shielding the sealing key 30 and the charging port 40 when the water tank 50 is in the first position.

In this manner, the tank 50 can slide relative to the second housing 11 to change the volume of the tank 50. When the tank 50 is in the second position, the tank 50 can be filled with more solution at maximum, and when the tank 50 is in the first position, the tank 50 is reduced in volume so that the dental irrigator 100 is more compact and lightweight. In addition, the key 30 and the charging interface 40 are disposed on the second housing 11, and when the water tank 50 is perpendicular to the first position, the water tank 50 shields the key 30 and the charging interface 40, so that water flow can be prevented from flowing through the key 30 and the charging interface 40 in the cleaning process.

Referring to fig. 7, in some embodiments, the key 30 and the charging interface 40 are disposed on different sides of the second housing 11. In this way, the key 30 and the charging interface 40 are disposed on different sides of the second housing 11, so that a user can perform the operation and charging of the key 30 at the same time, and timely water flows into the space between the water tank 50 and the second housing 11 and cannot flow through the key 30 and the charging interface 40 at the same time, thereby avoiding the risk of water inflow of the key 30 and the charging interface 40 at the same time.

In addition, in the present embodiment, the specific type of the dental irrigator 100 is not limited to meet different requirements, for example, the dental irrigator 100 may be a sliding dental irrigator 100, and the water tank 50 may be slid along the first direction with respect to the main body 10.
