Hereinafter, a dental caries device 1 according to an embodiment of the present application will be described with reference to the accompanying drawings.

As shown in fig. 1 and 2, the dental caries device 1 according to the embodiment of the present application includes a main body 100 and a water tank 200.

The top end of the body 100 may be connected to the nozzle 300, the water tank 200 is connected to the body 100, and the water tank 200 defines the water storage space 208 or defines the water storage space 208 together with the body 100. Wherein the water storage space 208 is used for storing a liquid for cleaning the oral cavity, such as clean water or mouthwash, etc. The pump body 400 is disposed in the body 100 for pumping the liquid in the water outlet space 208 to the nozzle 300.

Wherein, a buffer pad may be provided between the body 100 and the water tank 200, to increase friction between the body 100 and the water tank 200, to maintain a relative position between the body 100 and the water tank 200, and to reduce collision noise of the body 100 and the water tank 200.

In addition, the dental caries device 1 has a first direction (a direction indicated by an arrow a in the drawing) which is perpendicular to a longitudinal direction (a direction indicated by an arrow C in the drawing) of the dental caries device 1, and at least a part of the water tank 200 and the main body 100 are arranged in the first direction so that a center of gravity of the liquid of the water tank 200 is increased.

Since the height of the nozzle 300 is generally higher than that of the water tank 200, by arranging at least a portion of the water tank 200 and the main body 100 in the first direction, the center of gravity of the liquid in the water tank 200 is increased, the center of gravity of the liquid in the water tank 200 is closer to the nozzle 300 in the length direction of the tooth-rinsing device 1, the energy required for spraying the liquid in the water tank 200 after being pumped to the nozzle 300 is smaller, the energy can be saved, and the cruising ability of the tooth-rinsing device 1 can be improved.

And, after the center of gravity of the water tank 200 is increased, the distance between the center of gravity of the water tank 200 and the center of gravity of the machine body 100 in the length direction of the tooth-rinsing device 1 is shortened, which is favorable for the placement stability of the tooth-rinsing device 1 and prevents the tooth-rinsing device 1 from shaking under the placement condition.

As shown in fig. 1, the above-mentioned tooth-rinsing device 1 is arranged in at least one of the following ways:

The first type, the water tank 200 and the machine body 100 are arranged along the first direction, namely, the whole water tank 200 is positioned at the lateral direction of the machine body 100 along the first direction, so that the dimension of the whole water tank 200 and the whole machine body 100 along the length direction of the tooth-rinsing device 1 is smaller;

Secondly, a part of the water tank 200 is arranged with the machine body 100 along the length direction of the tooth-washing machine 1, and another part of the water tank 200 is arranged with the machine body 100 along the first direction, so that the water tank 200 limits the position of the machine body 100 along the length direction of the tooth-washing machine 1 and the first direction, the water tank 200 and the machine body 100 can play a role of supporting each other along the length direction of the tooth-washing machine 1, and the water tank 200 and the machine body 100 are not easy to separate;

thirdly, a part of the body 100 and the water tank 200 are arranged along the length of the tooth-rinsing device 1, and another part of the body 100 and the water tank 200 are arranged along the first direction, so that the body 100 defines the position of the water tank 200 in the length direction of the tooth-rinsing device 1 and the first direction, the water tank 200 and the body 100 can play a role of supporting each other in the length direction of the tooth-rinsing device 1, and the water tank 200 and the body 100 are not easy to separate.

Further, the water tank 200 surrounds the main body 100, so that the water tank 200 is arranged outside and the main body 100 is arranged inside, thereby not only facilitating arrangement of components in the main body 100, but also increasing the volume of the water tank 200, and the cruising ability of the tooth irrigator 1 is stronger.

Or the body 100 surrounds the water tank 200 such that the water tank 200 is inside, the body 100 is outside, the operation module 130 and the display module 140 are generally disposed on the body 100, the outer circumferential surface of the body 100 is convenient for a user to contact, the operation module 130 and the display module 140 are convenient to operate, and the arrangement positions of the operation module 130 and the display module 140 in the length direction of the tooth irrigator 1 are more, so that the structural flexibility of the tooth irrigator 1 is improved.

As shown in fig. 1 and 2, the top of the water tank 200 and the top of the machine body 100 may be flush, that is, the top of the water tank 200 and the top of the machine body 100 may be located on the same plane, so that steps do not occur between the top of the water tank 200 and the top of the machine body 100, and impurities are prevented from accumulating between the top of the water tank 200 and the top of the machine body 100, thereby reducing the probability of bacteria breeding in the tooth irrigator 1.

Since the top surface of the water tank 200 does not exceed the top surface of the body 200, the water tank 200 does not collide with teeth when the nozzle 300 is inserted into the mouth; the top surface that the high water tank 200 of fuselage 200 does not exceed, the water inlet 209 of water tank 200 can set up the top, need not be restricted by fuselage 200 when water tank 200 water injection, the water injection is more convenient, and because the slope when tooth-flushing device 1 uses, because nozzle 300 is in fuselage 100 side, the rivers that wash out flow downwards after entering the oral cavity, flow to the top of water tank 200, then flow along gravity direction again, can flow to the clearance between fuselage 100 and the water tank 200, the dirt is easy to be hidden between the contact surface of fuselage 100 and water tank 200, the side of fuselage 100 towards water tank 200 and the side of water tank 200 towards fuselage 100 set up the condition of connector (for example first interface 105 and second interface 205), also easily pollute above-mentioned connector, consequently the top surface of fuselage 200 does not surpass the top surface of water tank 200, prevent to form the step, reduce the probability of breeding the bacterium.

In addition, the bottom of the water tank 200 and the bottom of the machine body 100 can be arranged in parallel, the distance between the gravity center of the water tank 200 and the gravity center of the machine body 100 in the length direction of the tooth-flushing device 1 is closer, so that the placement stability of the tooth-flushing device 1 is facilitated, shaking is further avoided under the condition that the tooth-flushing device 1 is placed, the power required by pumping water is smaller, the energy conservation is facilitated, and the cruising ability is strong;

In some embodiments of the present application, the top of the water tank 200 is located at the same plane as the top of the body 100, and at this time, the top of the water tank 200 and the top of the body 100 may be disposed flush or inclined, so as to avoid a step structure formed at the transition between the top of the water tank 200 and the top of the body 100.

As shown in fig. 1 and 2, in the first direction, an operation module 130 and a display module 140 are provided at a side of the body 100 facing away from the water tank 200. The operation module 130 and the display module 140 may be connected to the circuit board 120.

That is, the display module 140 and the operation module 130 are located at the same side of the body 100, the display module 140 may be a display screen, at least a portion of the display module 140 is exposed from the body 100 so that a user can watch the content displayed by the display module 140, the operation module 130 may be a key, an operation lever, a sliding key, etc., and at least a portion of the operation module 130 is exposed from the body 100 so that the user can operate the operation module 130 to control the tooth device 1.

The operation module 130 and the water tank 200 are disposed on opposite sides of the main body 100 in the first direction, and when a user applies pressure to the operation module 130, the main body 100 is forced to move in the direction of the water tank 200, so that the main body 100 and the water tank 200 are prevented from being forced to be displaced in the second direction.

In addition, the operation module 130 is located above the display module 140, in the use process of the tooth cleaning device 1, the finger of the user may be always placed on the operation module 130, when the liquid sprayed by the nozzle 300 flows downwards, the finger can prevent the liquid from continuing to flow downwards, the probability of covering the display module 140 with the liquid is reduced, and the user always observes the display module 140 clearly, so that the experience is better.

The water tank 200 and the machine body 100 are arranged along the first direction, the cross-sectional area of the water tank 200 is S1, the cross-sectional area of the machine body 100 is S2, and the ratio of S1 to S2 is not less than 0.5 and not more than 2. Wherein the ratio of S1 to S2 may be 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9 or 2.

Alternatively, when the hose 420 is located between the first sidewall and the pump body 400, the clamping member may be disposed on the first sidewall and the pump body 400, and when the hose 420 is assembled, the hose 420 may be clamped between the first sidewall and the pump body 400, and the hose 420 is fixed between the first sidewall and the pump body 400 by the clamping member, so that the stability of assembling the hose 420 is improved.

Alternatively, when the hose 420 is positioned between the second housing 160 and the pump body 400, the clamping member may be provided on the second housing 160 and the pump body 400, and when the hose 420 is assembled, the hose 420 may be clamped between the second housing 160 and the pump body 400, and the hose 420 is fixed between the second housing 160 and the pump body 400 by the clamping member, thus improving the assembling stability of the hose 420.

As shown in fig. 4 and 5, the dental irrigator 1 further has a second direction (indicated by an arrow B in the drawing), and the first direction, the second direction and the longitudinal direction of the dental irrigator 1 are perpendicular to each other. The tooth cleaning device 1 further comprises a pump body 400, a circuit board 120 and a battery 500, wherein the pump body 400 is arranged in the machine body 100 and communicated with the water tank 200, and the pump body 400 is used for pumping liquid in the water tank 200. The circuit board 120 is disposed in the body 100 and connected to the pump body 400. The battery 500 is provided in the body 100 and connected to the pump body 400. The circuit board 120 and the pump body 400 are arranged along a first direction, the battery 500 and the pump body 400 are arranged along a second direction, and the pump body 400 and the battery 500 are located on the same side of the circuit board 120 along the first direction.

Thus, the pump body 400, the circuit board 120 and the battery 500 are arranged in a 'delta' shape, and the pump body 400, the circuit board 205 and the battery 500 are closely spaced from each other, so that the lengths of wires between the pump body 400, the circuit board 205 and the battery 500 are shortened, and the wiring is more convenient.

In addition, in the prior art, the pump body, the circuit board and the battery are arranged in a sandwich structure, that is, the pump body 400, the circuit board 120 and the battery 500 are arranged in a stacked manner along the first direction, so that the size of the machine body 100 in the first direction is too large, and the size of the machine body 100 in the second direction is too small, and if the machine body 100 and the water tank 200 are arranged along the first direction, the tooth flusher 1 is more unable to be held; or the pump body 400, the circuit board 120 and the battery 500 are stacked along the second direction, resulting in the body 100 having an undersize in the first direction, and the body 100 having an oversized dimension in the second direction, and at this time, the body 100 and the water tank 200 are arranged along the second direction, which results in the tooth-rinsing device 1 being more incapable of being held. Both of the above-described modes may cause the size of the body 100 in the first direction and the size in the second direction to be inconsistent, and the comfort of the user holding the dental irrigator 1 is low.

The tooth-rinsing device 1 in the embodiment of the application is approximately in a 'delta' arrangement, the dimension of the body 100 in the first direction is more similar to the dimension of the body 100 in the second direction, the proportion of the body 100 is coordinated, the holding by a user is facilitated, the water tank 200 can be arranged with the body 100 along the length direction of the tooth-rinsing device 1, the water tank 200 can be arranged with the body 100 along the first direction or the second direction, the tooth-rinsing device 1 cannot be held, and the layout flexibility of the tooth-rinsing device 1 is high.

The third, dental irrigator 1 further includes a bracket mounted to at least one of the pump body 400 and the main body 100, and at least one of the battery 500 and the circuit board 120 is mounted to the bracket. That is, the bracket may be connected to the pump body 400, the pump body 400 is connected to the body 100, or the bracket is connected to both the pump body 400 and the body 100, so that the bracket is not displaced in the body 100, and the relative positions of the bracket and the body 100 are stable. At least one of the battery 500 and the circuit board 205 may be mounted to the bracket, that is, the battery 500 may be mounted to the bracket, or the circuit board 205 may be mounted to the bracket, or both the battery 500 and the circuit board 205 may be mounted to the bracket. Thus, at least one of the battery 500 and the circuit board 205 is fixed at a position opposite to the machine body 100 directly, so that the pump body 400 is not required to be processed, the processing difficulty of the pump body 400 is reduced, and the production efficiency is improved.

As shown in fig. 4, a water inlet 209 and a water drawing assembly are provided on a side of the pump body 400 facing away from the battery 500, and the water drawing assembly is respectively communicated with the water inlet 209 and the water tank 200. Thus, the water inlet 209 and the battery 500 are positioned on two opposite sides of the pump body 400 in the second direction, so that the battery 500 is prevented from influencing the communication between the water inlet 209 and the water inlet flow channel 430, and when the water inlet 209 leaks, liquid is difficult to flow to the battery 500, the battery 500 is prevented from being short-circuited, and the circuit safety of the tooth cleaner 1 is improved.

As shown in fig. 4 to 6, the pumping assembly further includes a hose 420, an interface member 430, and a filter member 440. The hose 420 is connected with the pump body 400, the interface member 430 is connected with the hose 420 and is communicated with the water storage space 208, and the filter member 440 is provided at the interface member 430 for filtering the liquid flowing from the interface member 430 to the hose 420.

In this way, the hose 420 can connect the interface 430 and the pump body 400, the hose 420 can change its shape according to the arrangement of the inside of the body 100, so that the communication between the interface 430 and the pump body 400 is facilitated, and the flexibility of the layout of the dental irrigator 1 is improved.

By providing the mouthpiece 430, the hardness of the mouthpiece 430 may be greater than that of the hose 420, and the mouthpiece 430 is capable of changing the flow direction of the liquid, ensuring that the liquid of the first port 105 flows more smoothly to the hose 420. In addition, the interface 430 may be fixedly connected to the body 100, for example, the interface 430 may be fixedly connected to the body 100 by a threaded fastener, so as to avoid relative displacement between the interface 430 and the body 100, so that the two ends of the hose 420 are fixed to the body 100, and the hose 420 is prevented from shaking in the body 100.

In addition, before the liquid flows into the hose 420, the liquid flows through the filter 440, and impurities and the like in the liquid are removed by the filter 440, so that the cleanliness of the liquid in the hose 420 is improved, the cleanliness of the liquid sprayed by the nozzle 300 is further improved, the teeth cleaning of the tooth cleaning device 1 is safer, and the oral health condition of a user is improved.

The pump body 400 has a first joint, the first joint is provided with a water inlet 209, the hose 420 is sleeved on the first joint, and the first joint extends to the interface member 430. That is, the diameter of the first connector is smaller than the diameter of the hose 420, so the flow rate of the liquid at the first connector is faster and the liquid is ejected from the nozzle faster.

Furthermore, since the end of the hose 420 is sleeved with the first joint 2211, the connection between the hose 420 and the first joint is stable, and thus, the connection stability between the hose 420 and the pump body 400 is improved.

When the first connector extends to the connector 430, the hose 420 can be shortened, so that the material preparation cost of the hose 420 is saved, and meanwhile, the first connector faces to the connector 430, so that the hose 420 can be conveniently connected with the first connector, and the assembly efficiency of the hose 420 and the pump body 400 is improved.

As shown in fig. 6, the connector 430 has a second joint 431, the hose 420 is sleeved on the second joint 431, and the second joint 431 extends toward the pump body 400. That is, the diameter of the second joint 431 is also smaller than the diameter of the hose 420, so that when the pump body 400 is operated, the liquid in the tank 200 is sucked to the mouthpiece 430, since the diameter of the second joint 431 is smaller than the diameter of the hose 420, the flow rate of the liquid at the second joint 431 is faster, thus facilitating the rapid flow of the liquid into the hose 420.

Furthermore, since the hose 420 is sleeved with the second connector 431, the connection between the hose 420 and the second connector 431 is stable, and thus, the stability of the connection between the hose 420 and the interface 430 is improved.

When the second joint 431 extends toward the pump body 400, the hose 420 is shortened, so that the material preparation cost of the hose 420 is saved, and meanwhile, the second joint 431 is disposed toward the pump body 400, so that the hose 420 and the second joint 431 can be conveniently connected, and the assembly efficiency of the hose 420 and the connector 430 is improved.

As shown in fig. 6, the water drawing assembly further includes a pressing member 450, the pressing member 450 may be elastically deformed, the pressing member 450 may be made of a soft rubber material such as a rubber member or a silicone member, the interface member 430 is provided with a receiving groove 432, the filtering member 440 is disposed in the receiving groove 432, the pressing member 450 is disposed in the receiving groove 432, and the filtering member 440 is clamped between the pressing member 450 and a bottom wall of the receiving groove 432.

That is, the filter member 440 is clamped between the interface member 430 and the pressing member 450 in the axial direction of the receiving groove 432, so that the filter member 440 is prevented from being displaced relative to the interface member 430, and the liquid flowing into the hose 420 is ensured to pass through the filter member 440, thereby further improving the cleanliness of the liquid in the hose 420.

In addition, since the interface member 430 is provided with the accommodating groove 432, the accommodating groove 432 is used for accommodating the filter member 440 and the pressing member 450, and the relative positions of the pressing member 450 and the interface member 430 can be fixed, so that the relative positions among the filter member 440, the interface member 430 and the pressing member 450 are kept stable.

In addition, the inner wall of the body 100 is provided with a pressing protrusion 104, and a part of the pressing member 450 is provided between the end surface of the pressing protrusion 104 and the bottom wall of the accommodation groove 432, and another part of the pressing member 450 is sandwiched between the outer circumferential surface of the pressing protrusion 104 and the inner circumferential surface of the accommodation groove 432.

That is, a portion of the pressing member 450 can be pressed by the end of the pressing protrusion 104 to be tightly attached to the filter member 440, and the portion can be elastically deformed to be filled between the end of the pressing protrusion 104 and the bottom wall of the accommodating groove 432, so that, on one hand, the filter member 440 can be prevented from moving in the accommodating groove 432, the filtering effect of the filter member 440 is ensured, and on the other hand, the liquid is prevented from flowing out from between the end of the pressing protrusion 104 and the bottom wall of the accommodating groove 432, and the probability of leakage of the liquid into the body 100 is reduced.

Another portion of the pressing member 450 can be pressed between the outer circumferential surface of the pressing protrusion 104 and the inner circumferential surface of the receiving groove 432, and the portion can be elastically deformed to fill between the outer circumferential surface of the pressing protrusion 104 and the inner circumferential surface of the receiving groove 432, so that leakage of the liquid into the body 100 from between the outer circumferential surface of the pressing protrusion 104 and the inner circumferential surface of the receiving groove 432 can be prevented, the probability of leakage of the liquid into the body 100 can be further reduced, the liquid in the receiving groove 432 can be ensured to flow to the hose 420 through the filter member 440, and the probability of short-circuiting of the electrical components in the body 100 can be reduced.

In the practical use process, the liquid is easy to adhere to the surface of the water tank 200, for example, when the liquid remains on the inner wall of the water tank 200, the inner wall of the water tank 200 is not easy to be cleaned, and if the cleaning tool 1 is not used by a user for a long time, bacteria can be easily bred in the water tank 200 due to the liquid remaining on the inner wall of the water tank 200, and the health and safety of the user are affected

Thus, a water-repellent layer is provided on the inner wall of the water tank 200. It is understood that the inner wall of the water tank 200 may be entirely provided with a water-repellent layer, or partially provided with a water-repellent layer. The hydrophobic layer may include at least one of a hydrophobic film and a hydrophobic nano structure, the hydrophobic film may be attached to or coated on the wall surface of the water tank 200, and the hydrophobic nano structure may be directly formed on the wall surface of the water tank 200 by a processing method, for example, nanoparticles, nanowires, or nanotubes are formed on the wall surface of the water tank 200.

Thus, the inner wall of the water tank 200 is provided with the hydrophobic layer, so that the liquid which is originally adhered to the inner wall of the water tank 200 cannot adhere to the inner wall of the water tank 200, and can flow to the bottom of the water tank 200 along the inner wall of the water tank 200, so that the cleaning appliance 1 is more easily sucked clean by the pump body 400 when in use, the inner wall of the water tank 200 is not easy to be adhered with the liquid, and the risk of bacteria breeding in the water tank 200 under the condition that the cleaning appliance 1 is not used for a long time is reduced. In addition, the user does not need to specially take paper towels or the like after finishing using, and the inner wall of the water tank 200 is specially cleaned, so that the convenience of cleaning the inner wall of the water tank 200 is improved for the user.

For another example, the outer wall of the water tank 200 is generally provided with a gap to increase the friction coefficient of the outer wall of the water tank 200, so that a user can hold the outer wall of the water tank 200 more firmly when using the cleaning appliance 1, and the situation that the cleaning appliance 1 is separated from the hand of the user or the operation of the user is unstable due to the wet hand of the user or the excessive sliding of the water tank 200 is prevented, it is understood that during the use of the cleaning appliance 1, the liquid flushed during tooth flushing can partially flow to the outer wall of the water tank 200, and on the basis of the existence of the gap, the liquid can easily remain in the gap, and the user usually wipes the liquid in the gap, so that bacteria can easily grow in the gap.

When the liquid is stuck on the outer wall of the water tank 200, after the user finishes using the cleaning tool 1, the user needs to take a paper towel or towel, etc., and specifically cleans the outer wall of the water tank 200, otherwise, the hands, clothes or bags of the user are wetted.

Whereby the outer wall of the water tank 200 is provided with a hydrophobic layer. Also, the outer wall of the water tank 200 may be entirely provided with a water-repellent layer, or partially provided with a water-repellent layer. The hydrophobic layer may include at least one of a hydrophobic film and a hydrophobic nano structure, the hydrophobic film may be attached to or coated on the wall surface of the water tank 200, and the hydrophobic nano structure may be directly formed on the wall surface of the water tank 200 by a processing method, for example, nanoparticles, nanowires, or nanotubes are formed on the wall surface of the water tank 200.

In this embodiment, the hydrophobic layer is disposed on the outer wall of the water tank 200, so that the liquid that is originally adhered to the outer wall of the water tank 200 cannot adhere to the outer wall and cannot adhere to the gap of the outer wall, thereby reducing the risk of bacteria breeding in the outer wall and the gap of the water tank 200. In addition, even if a part of liquid is attached to the outer wall and in the gap of the outer wall, the user only needs to throw the water tank 200 lightly, the liquid can fall off, the operation is very convenient, and the liquid is prevented from wetting the hands, clothes or bags of the user.

Further, the above-mentioned tooth-rinsing device 1 is constructed in at least one of the following ways:

Firstly, the machine body 100 and the hydrophobic layer are arranged at intervals, at this time, the water tank 200 and the machine body 100 can be in non-movable connection, and the non-movable connection mode refers to that the water tank 200 and the machine body 100 do not move relatively, such as do not move relatively, slide or rotate relatively, so that the machine body 100 can be prevented from scratching the hydrophobic layer arranged on the outer wall of the water tank 200 or the inner wall of the water tank 200 or scraping the hydrophobic layer to cause failure of the hydrophobic layer when the machine body 100 moves relatively to the water tank 200; the water tank 200 and the machine body 100 can be movably connected, namely, the water tank 200 and the machine body 100 can move relatively, and the machine body 100 is not contacted with the hydrophobic layer arranged on the outer wall of the water tank 200 or the hydrophobic layer arranged on the inner wall of the water tank 200, so that the machine body 100 can be prevented from scratching the hydrophobic layer arranged on the outer wall of the water tank 200 or the hydrophobic layer arranged on the inner wall of the water tank 200 or scraping the hydrophobic layer to cause failure of the hydrophobic layer when the machine body 100 slides relatively to the water tank 200.

As shown in fig. 2, the second type of water tank 200 is provided with a water inlet 209, the water inlet 209 is provided with an end cover 600, and the end cover 600 is movably connected with the water tank 200 to open or close the water inlet 209, that is, when liquid needs to be injected into the water tank 200, the end cover 600 can be controlled to open the water inlet 209, and after the injection is completed, the end cover 600 can be controlled to close the water inlet 209, so that the operation is convenient, and the risk of liquid overflow can be reduced when the water inlet 209 is closed. Illustratively, the end cap 600 may be slidably connected, inserted, hinged, or the like to the water tank 200.

And, the end cover 600 is spaced apart from the hydrophobic layer in such a manner that the end cover 600 can prevent the hydrophobic layer from being scratched or scraped off to cause the failure of the hydrophobic layer.

As shown in fig. 2, the third type of water tank 200 is provided with a water inlet 209, the water inlet 209 is provided with an end cover 600, the end cover 600 is movably connected with the water tank 200 to open or close the water inlet 209, so that the water inlet 209 is opened or closed, that is, when liquid needs to be injected into the water tank 200, the end cover 600 can be controlled to open the water inlet 209, and after the injection is completed, the end cover 600 can be controlled to close the water inlet 209, so that the operation is convenient, and the risk of liquid overflow can be reduced when the water inlet 209 is closed. Illustratively, the end cap 600 may be slidably connected, inserted, hinged, or the like to the water tank 200.

In addition, the portion of the end cap 600 extending into the water tank 200 (i.e., the insertion section 610 and the pull pin 620 described below) is made of soft rubber, so that even if the portion of the end cap 600 extending into the water tank 200 contacts the hydrophobic layer, the portion of the end cap 600 extending into the water tank 200 has less scratch on the hydrophobic layer or the probability of scraping the hydrophobic layer due to the soft rubber, and the hydrophobic layer can be better protected.

As shown in fig. 7, a fourth type of water tank 200 is provided with a water drawing pipe 207, the water drawing pipe 207 is communicated with the machine body 100, the liquid amount remained in the water tank 200 is effectively reduced by the arrangement of the water drawing pipe 207, the leakage probability of the liquid in the process of being transmitted from the water tank 200 to the pump body 400 is reduced, and furthermore, the arrangement of the water drawing pipe 207 is convenient for the butt joint operation of the pump body 400 and the water tank 200, so that the butt joint is quicker and more accurate.

The water drawing pipe 207 is spaced apart from the drain pipe. Thus, the drain pipe 207 can be prevented from scratching the hydrophobic layer or scraping the hydrophobic layer off to cause failure of the hydrophobic layer.

As shown in fig. 7, a water drawing pipe 207 is disposed in the fifth water tank 200, the water drawing pipe 207 is communicated with the machine body 100, and by the arrangement of the water drawing pipe 207, the liquid amount remained in the water tank 200 is effectively reduced, and the probability of leakage of the liquid in the process of being transmitted from the water tank 200 to the pump body 400 is advantageously reduced, and furthermore, the arrangement of the water drawing pipe 207 is also convenient for the butt joint operation of the pump body 400 and the water tank 200, so that the butt joint is quicker and more accurate.

Further, the water drawing pipe 207 is deformed when it contacts the water-repellent layer. Thus, even though the drain pipe 207 is moved in position with respect to the water tank 200 and contacts the water-repellent layer, the probability of scratching the water-repellent layer or scraping the water-repellent layer due to the soft nature of the hose 420 can be effectively reduced by the drain pipe 207 as the hose 420.

As shown in fig. 2, the above-described dental irrigator 1 further includes a nozzle 300 and an end cap 600. The nozzle 300 is connected with the top end of the body 100, the top end of the water tank 200 or the top end of the body 100 is provided with a water inlet 209, and the water inlet 209 is communicated with the water storage space 208.

That is, whether the water inlet 209 is provided at the top end of the entire body of the dental caries device 1 (except for the nozzle 300) or the water tank 200, in this case, the dental caries device 1 is maintained in a vertical state (i.e., the length direction of the dental caries device 1 extends in the up-down direction) when water is injected into the dental caries device 1, the state of the dental caries device 1 when water is injected and the state of the dental caries device 1 when in use are maintained in agreement, and the dental caries device 1 does not need to be turned over or rotated, so that the user does not need to excessively turn the wrist, and the use of the dental caries device 1 is more convenient.

In addition, the cover 600 is reversible between an open state and a closed state with respect to the water inlet 209, and in the case where the cover 600 is switched from the closed state to the open state, the cover 600 is turned toward the direction of the nozzle 300. The water inlet 209 is capped when the end cap 600 is in a closed state, the water inlet 209 is opened by abutting the nozzle 300 when the end cap 600 is in an open state, and the water storage space 208 communicates with the atmosphere through the water inlet 209.

Thus, when the end cover 600 is in the closed state, the water inlet 209 is sealed, so that on one hand, liquid in the water tank 200 is prevented from leaking from the water inlet 209, and on the other hand, external dirt and impurities are prevented from entering the water tank 200, the cleanliness of the liquid in the water tank 200 is ensured, and the tooth cleaner 1 is safer for cleaning the oral cavity. When the end cover 600 is in the open state, the end cover 600 is abutted against the nozzle 300, the free end of the end cover 600 and the nozzle 300 are approximately in the same position, so that the water injection device avoids the nozzle 300, meanwhile, the end cover 600 is avoided to a certain extent, the blockage of hands and the nozzle 300 to the water injection device is smaller, the relative position between the tooth flushing device 1 and the water injection device is more flexible, the water injection to the tooth flushing device 1 is more convenient, and the water injection is convenient for a user after the end cover 600 is opened.

As shown in fig. 2, further, the end cover 600 is provided with a plugging section 610 and a pull-up pin 620, the plugging section 610 is plugged into the water inlet 209 and is sealed against the inner wall of the water inlet 209, a through hole 621 is provided between the water inlet 209 and the nozzle 300 in the radial direction of the tooth cleaner 1, the pull-up pin 620 is plugged into the through hole 621, and the pull-up pin 620 is limited by the side wall of the through hole 621 along the axial direction of the through hole 621.

Wherein, during the process of the end cover 600 being turned from the closed state to the open state, the plug portion 410 is gradually pulled out from the water inlet 209. So, grafting portion 410 can seal water inlet 209, prevents on the one hand that the liquid in the water tank 200 from leaking from water inlet 209, and on the other hand avoids external dirty impurity to get into water tank 200, guarantees the cleanliness of the interior liquid of water tank 200, and tooth cleaning machine 1 is safer to the cleanness in oral cavity.

When the end cover 600 is switched from the open state to the closed state, the plug part 410 is pulled out from the water inlet 209 and turned over towards the direction of the nozzle 300, in this process, the pull-up nail 620 gradually moves upwards, and under the condition that the end cover 600 is stopped against the nozzle 300, the pull-up nail 620 and the side wall of the through hole 621 can be stopped against each other to prevent the pull-up nail 620 from being separated from the through hole 621, so that when the end cover 600 is switched from the closed state to the open state, the relative position between the pull-up nail 620 and the water tank 200 and the machine body 100 is determined, the plug part 410 is inserted into the water inlet 209 more accurately, and the end cover 600 is switched between the open state and the closed state more conveniently.

Since the through hole 621 is located between the water inlet 209 and the nozzle 300, the dimension of the movement of the pull tab 620 is smaller than the dimension of the movement of the insertion portion 410, and thus the pull tab 620 can be prevented from being separated from the through hole 621 when the cover 600 is in the opened state.
