It is understood that the main body 11 and the water tank 12 are separately formed, but not integrally formed, and the main body 11 and the water tank 12 are separately formed and detachably provided by hands, and it is more suitable for detaching the water tank 12 from the body 10 to add a washing liquid such as water to the water tank 12. The length of the cross section of the flat column refers to the maximum distance in the up-down direction thereof as indicated by H1 in fig. 4, and the width of the cross section of the flat column refers to the maximum distance in the left-right direction thereof as indicated by H2 in fig. 4. The whole body of the machine body 10 is a flat cylinder, and the shape of the flat main body is generally matched with the shape of the hand held by the human body, so that the machine body 10 is more convenient to hold. It should be further noted that the boundary line between the main unit 11 and the water tank 12 in the length direction of the main body 10 in the present embodiment is the boundary line between the main unit 11 and the water tank 12 on the outer surface of the main body 10, i.e., the boundary line between L1 and L2 shown in fig. 1.

Further, since the length from the top end of the main body 11 to the boundary line in the present embodiment is 6.0cm to 14.0cm, for example, 6cm, 8cm, 10cm, 14cm, or 14 cm. And the ratio of the length L1 of the main machine 11 to the length L2 of the water tank 12 is 3:7 to 7:4, e.g. 6: 7. 8: 7. 10:7 or 7:4, etc. At the same time, the cross-sectional area of the tooth flusher at the boundary line is 15.0cm ² To 30.0cm ² E.g. 15.0cm ² 、20.0cm ² 、25.0cm ² Or 30.0cm ² And the length of the cross section of the tooth irrigator at the dividing line is not more than 9cm, such as 4cm, 6cm, 8cm and the like.

In some embodiments, the main body 11 and the water tank 12 are fixed to each other, and it is understood that the mutual fixation refers to a fixing manner that the main body 11 and the water tank 12 are fixed to each other and cannot be displaced relative to each other after the main body 11 and the water tank 12 are assembled together, and in this case, a boundary line formed by the main body 11 and the water tank 12 on the outer surface of the body 10 is the above-mentioned boundary line.

In other embodiments, the host 11 and the water tank 12 can slide relative to each other, specifically, the water tank 12 is sleeved on the periphery of the host 11, and when the water tank 12 slides along the periphery of the host 11, the internal volume of the water tank 12 can be adjusted, and then the liquid storage amount of the water tank 12 can be adjusted. The water tank 12 has a first limit position sliding to be closest to the nozzle 20 and a second limit position sliding to be farthest from the nozzle 20, and at this time, the length from the top end of the main body 11 to the cross-connecting line is the length from the top end of the main body 11 to the second limit position, that is, the length from the top end of the main body 11 to the end of the water tank 12 close to the nozzle 20 when the water tank 12 is at the second limit position.

Further, the main unit 11 in this embodiment includes a housing 111, the housing 111 encloses to form an installation cavity, a power supply unit 112 and a pumping device 113 are disposed in the installation cavity of the housing 111, the power supply unit 112 is electrically connected to the pumping device 113, and the pumping device 113 is configured to pump the liquid in the water tank 12 to the water outlet channel 21. Specifically, the pumping device 113 in this embodiment is disposed on the channel 50, and when the pumping device 113 works, the liquid in the water tank 12 can be pumped into the water outlet channel 21 on the nozzle 20, and then ejected from the nozzle 20 for cleaning the oral cavity of the human body. Optionally, the pumping device 113 in this embodiment is a water pump, and the power supply unit 112 includes at least one battery block, which may be a storage battery or a rechargeable battery, so as to supply power to the pumping device 113 to provide necessary electric energy for the operation of the pumping device 113.

Further, since the pumping device 113 and the power supply unit 112 are disposed inside the main body 11, the main body 11 has a certain weight, and when the dental irrigator 100 is vertically placed in a horizontal position, the center of gravity is high, and the main body 10 is prone to toppling. For this reason, in the present embodiment, the cross-sectional area of the body 10 is gradually reduced in the direction from the water tank 12 to the main body 11, that is, the cross-sectional area of the body 10 on the side close to the water tank 12 is larger, the cross-sectional area on the side close to the main body 11 is smaller, the side close to the water tank 12 is thicker, and the main body 11 is thinner, so that when the tooth flusher 100 is placed in a horizontal plane, the center of gravity of the tooth flusher 100 can be moved downward (the center of gravity is closer to the bottom of the water tank 12), and the body 10 is not prone to toppling. Preferably, during the actual installation process, one end of the main body 11 close to the inside of the water tank 12 can be extended into the water tank 12, so as to further lower the center of gravity of the main body 10.

Meanwhile, the cross-sectional area of the body 10 is gradually reduced along the direction from the water tank 12 to the main unit 11, so that the capacity of the water tank 12 can be increased, more liquid can be contained, the center of gravity of the body 10 can be further lowered, and the use by a user is facilitated. It should be noted that the center of gravity of the body 10 is related to the amount of water contained in the water tank 12, and the center of gravity is closer to the top end of the body 10 (i.e. closer to the main unit 11) as the amount of water is larger, and in this embodiment, by gradually reducing the cross-sectional area of the body 10 along the direction from the water tank 12 to the main unit 11, the center of gravity of the body 10 can be lowered to some extent compared with a structure in which the cross-sectional area of the body 10 is not changed.

In order to control and operate the dental irrigator 100, the main body 11 in this embodiment is provided with an operation button 114 and a power button 116, and the operation button 114 and the power button 116 are arranged on the narrower side of the main body 11. It will be understood that the narrower side of the main body 11 as described herein refers to the flatter side of the flattened cylinder (as shown at the two lengthwise ends in fig. 4). In the actual use process, the user holds the machine body 10, the narrow side face of the machine body 10 is located on the first web side of the hand, the external shape of the machine body 10 is matched with the handheld shape of the hand of the human body, at the moment, the user can touch the key 114 or the power supply key 116 only by vertically placing the thumb, the machine body is more suitable for the user to operate and use the operation key 114, and the machine body is more in line with the ergonomic design.

Since the frequency of use of the power button 116 is lower than that of the operation button 114, in the embodiment, the power button 116 is located at one end of the operation button 114 close to the nozzle 20, so that when the user holds the main body 10, the operation button 114 is closer to the thumb of the user, which is convenient for the user to operate the operation button 114.

Referring to fig. 3 to 5, the operation keys 114 in this embodiment at least include a switch key 1141 and a dot impact mode key 1142, wherein the switch key 1141 and the dot impact mode key 1142 are sequentially arranged along a direction from the water tank 12 to the main body 11. It is understood that when the switch key 1141 is pressed, the nozzle 20 continues to discharge water, and when the switch key 1141 is not pressed, the nozzle 20 stops discharging water; when the punch button 1142 is continuously pressed, the nozzle 20 discharges water, and when the punch button 1142 is released, the nozzle 20 stops discharging water. When actually using the tooth flushing device 100, the user's hand holds the main machine 11 and the water tank 12 at the same time, at this moment, the user's thumb can press the switch button 1141 and the dot die button 1142, and the dot die button 1142 needs to be pressed all the time or pressed at intervals when in use, the operation frequency is higher, therefore, the dot die button 1142 is arranged on one side of the main machine 11 close to the nozzle 20, namely, the dot die button 1142 is closer to the finger tip of the thumb than the switch button 1141, which is convenient for the user to press the dot die button 1142. If the click mode button 1142 is too close to the tank 12, the thumb may be bent during operation of the click mode button 1142, which may cause discomfort and may cause the thumb to be cramped. It should be noted that the design of the click-to-die button 1142 is for the purpose of caring for the novice user, i.e., to stop and start. Compared with the conventional method of only providing the switch 1141, the tooth irrigator 100 of the embodiment can satisfy different use requirements of people.

Illustratively, the clear distance L3 between the point impact mode key 114 and the water tank 12 is 3.5cm to 5.5cm, such as 3.5cm, 4cm, 4.5cm, 5cm, or 5.5cm, etc. With the arrangement, when a user holds the main body 10, the web part of the hand of the human body is approximately positioned near the joint position of the water tank 12 and the main body 11, the length of the thumb determines the pressing range of the thumb, the length of the thumb of most adults is 3.5cm to 5.5cm, namely, the clear distance L3 between the point impact mode key 114 and the water tank 12 is set to be 3.5cm to 5.5cm, and the length is matched with the length of the thumb of most adults, so that the point impact mode key 114 can be conveniently operated by the thumb.

Of course, in other embodiments of the present invention, the switch key 1141 and the click mode key 1142 may be disposed along the periphery of the main unit 11, and any other deformation modes under the concept of the present invention are all within the protection scope of the present invention.

In the actual design process, the switch key 1141 and the stamping die type key 1142 may be arranged at an interval, or may be arranged closely, and in this embodiment, the switch key 1141 and the stamping die type key 1142 are preferably arranged at an interval, so that the condition discovery that the key is pressed by mistake (for example, the stamping die type key 1142 is pressed simultaneously when the switch key 1141 is pressed) can be avoided to a certain extent.

In order to facilitate the processing, the service life of the operation key 114 in this embodiment is prolonged, so that the switch key 1141 and the click die type key 1142 are integrally arranged, that is, the switch key 1141 and the click die type key 1142 are processed and formed on a structural member, and in the direction from the water tank 12 to the host 11, the axial distance between the key 114 and the center of the water tank 12 is gradually reduced, which is convenient for the thumb of the user to lean on, and is convenient for the user to use and operate.

The operation key 114 is illustratively a silicone key, and the friction between the operation key 114 and the hand of the user can be increased by the action of the silicone key, so as to avoid slipping from the operation key 114.

Of course, in other embodiments of the present invention, the operation button 114 may be a hard button, and then the operation button 114 may be provided with a structure such as a raised grain to play an anti-slip role.

In some embodiments, there is a smooth transition between the outer surface of the main body 11 and the outer surface of the water tank 12. That is, the outer surfaces of the ends of the main body 11 and the water tank 12 close to each other are aligned with each other, and the outer surfaces of the abutting ends of the two close to each other have no obvious concave-convex feeling, so that the main body 10 is more suitable for a user to hold and is less prone to hurting hands.

Of course, in other embodiments, a step surface may be formed between the outer surface of the main unit 11 and the outer surface of the water tank 12, for example, when the water tank 12 is sleeved on the outer periphery of the main unit 11, the step surface formed between the end surface of the water tank 12 and the outer surface of the main unit 11 is only required to be in other deformation modes under the concept of the present invention, which is within the protection scope of the present invention. It should be noted that, when a step surface is formed between the outer surface of the main body 11 and the outer surface of the water tank 12, the cross section of the tooth flushing device 100 at the boundary line is: at the boundary line, the smaller cross section of both the main body 11 and the water tank 12.

Referring to fig. 2, in order to connect the main unit 11 and the water tank 12 together, a first connection portion 1101 is provided on the main unit 11, a second connection portion 121 adapted to the first connection portion 1101 is provided on the water tank 12, and the main unit 11 and the water tank 12 are detachably connected by the first connection portion 1101 and the second connection portion 121 by hands, so that the water tank 12 can be detached from the main unit 11 to add a flushing liquid and the like.
