[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the relevant invention are shown in the accompanying drawings.

[0029] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] The utility model proposes a multi-layer water tank water flosser. Figure 1 The overall structure diagram of the multi-layer water tank water flosser according to the utility model in the use state is shown as follows: Figure 1 and Figure 2 As shown, the multi-layer water tank water flosser comprises a nozzle 1, a water flosser body 2 and a water tank assembly 3. The water tank assembly 3 has a cavity inside and is connected to the water flosser body 2, and the nozzle 1 is arranged on one side of the water flosser body 2.

[0031] The water tank assembly 3 includes at least two layers of water tanks that can be extended and retracted along the height direction of the water flosser body 2 to change the volume. The internal cavity of the water tank assembly 3 is connected to the water flosser body 2, and the water tank assembly 3 and the water flosser body 2 are engaged with each other through the clamping assembly 4. The multi-layer water tank can increase the volume of the water flosser, and the design of the telescopic water tank can optimize the overall size of the water flosser. The storage volume is small enough for easy carrying and storage.

[0032] Specifically, in this embodiment, if Figure 2 As shown, the water tank assembly 3 is configured as two layers, including an inner water tank 31 and an outer water tank 32. The inner water tank 31 can be stretched along the main shell of the water flosser body 2, and the outer water tank 32 is inverted on the inner water tank 31. Through the snap fit of the snap assembly 4, the outer water tank 32 is removed and loaded from the bottom of the inner water tank 31 during use; after use, the water tank is folded into a storage state for easy carrying.

[0033] Specifically, when in use, the two ends of the inner water tank 31 are respectively engaged with the water flosser body 2 and the outer water tank 32 through the snap-fit ​​assembly 4. When stored, the inner water tank 31 is sleeved on the water flosser body 2, and the outer water tank 32 is inverted on the top of the water flosser body 2, so that the inner water tank 31 and the water flosser body 2 are stored inside.

[0034] Further, such as Figure 3 and 4As shown, a support plate 5 is provided on one side of the inner water tank 31 away from the main body 2 of the water flosser, and the support plate 5 is protrudingly provided on the inner side wall of the inner water tank 31. A storage cavity 6 for accommodating the nozzle 1 when stored is provided inside the main body 2 of the water flosser, and the end of the nozzle 1 abuts against the support plate 5 when stored. A handle 7 is provided on the support plate 5.

[0035] The design of the storage chamber 6 facilitates the hiding of the nozzle 1. The nozzle 1 can be hidden in the storage chamber 6 when not in use, and can be taken out when in use, which is more convenient and practical. The support plate 5 is provided at the lower end of the inner water tank 31 to play a limiting role, preventing the suction pipe 10 and the nozzle 1 from leaking out when stored. The handle portion 7 provided on the support plate 5 can be used as a handle to facilitate pulling out the water tank when using the water flosser.

[0036] Specifically, in this embodiment, if Figure 2 and Figure 5 The snap-on assembly 4 includes an inner water tank outer convex snap-on 41, an inner water tank inner convex snap-on 42, an outer water tank inner concave snap-on 43 and a main shell outer convex snap-on 44 that can be snap-on-matched with each other. The inner water tank outer convex snap-on 41 is protrudingly arranged on the outer wall of the inner water tank 31, the inner water tank inner convex snap-on 42 is protrudingly arranged on the inner wall of the inner water tank 31, the outer water tank inner concave snap-on 43 is arranged on the inner wall of the outer water tank 32, and the main shell outer convex snap-on 44 is symmetrically arranged on the outer wall of the water flosser body 2. The main shell outer convex snap-on 44 includes an upper snap-on 441 and a lower snap-on 442 located one above the other, and a concave avoidance groove 8 is arranged on the outer wall of the main shell outer convex snap-on 44 on the water flosser body 2.

[0037] It should be noted that the specific design position and quantity combination of the snap-in assembly 4 are not specifically limited here, as long as the snap-in fit effect can be achieved. In other embodiments, the snap-in assembly 4 can also be set as a snap-in fit of a slide groove and a slider. Accordingly, the snap-in assembly 4 can be specifically designed with some specific designs that optimize the snap-in fit, such as a guide portion, a guide groove, etc., which are not specifically limited here.

[0038] Furthermore, in the present embodiment, the height of the outer water tank 32 is greater than that of the inner water tank 31 and the oral irrigator body 2, so as to ensure that the inner water tank 31 and the oral irrigator body 2 can be completely wrapped therein when stored.

[0039] Further, such as Figure 5 As shown, a pump group 9 and a water suction pipe 10 are provided inside the water flosser body 2, and the nozzle 1 is connected to the inner water tank 31 and the outer water tank 32 through the water suction pipe 10. A water injection port 11 is provided on the water flosser body 2, and a sealing cover 12 is provided on the water injection port 11, and the water injection port 11 is close to the nozzle 1.

[0040] It should be noted that the functional components inside the oral irrigator of this embodiment are basically the same as those of the existing oral irrigators, such as the PCB board circuit, nozzle holder, power supply, charging module, switch button, etc., and will not be introduced in detail here.

[0041] Specifically, the oral irrigator of this embodiment has the following two working states:

[0042] Working state 1: Storage state

[0043] like Figure 3 and Figure 4 As shown, the outer wall of the inner water tank 31 is provided with a convex inner water tank convex buckle 41, the inner wall of the inner water tank 31 is provided with a convex inner water tank convex buckle 42, and the lower end of the inner water tank 31 is provided with a protruding support plate 5; the inner wall of the outer water tank 32 is provided with a concave outer water tank concave groove 43; the two symmetrical outer side surfaces of the main shell of the water flosser body 2 are provided with convex main shell convex buckles 44, the main shell convex buckles 44 include an upper buckle 441 and a lower buckle 442, and the side is provided with a concave avoidance groove 8.

[0044] When in the storage state, the outer water tank 32 is mounted and buckled on the outer side wall of the inner water tank 31 in an inverted manner, and the concave groove 43 in the outer water tank is snap-fitted with the convex buckle 41 of the inner water tank and plays a limiting role; the inner wall of the inner water tank 31 is fitted with the outer wall of the main shell of the water flosser body 2, and the corresponding inner convex buckle 42 of the inner water tank on the inner wall of the inner water tank 31 is snapped with the convex buckle 44 of the main shell on the water flosser body 2, that is, the inner convex buckle 42 of the inner water tank is snapped with the upper buckle 441; then the water suction pipe 10 and the nozzle 1 are stored in the storage cavity 6 of the main shell, the support plate 5 can be used as a handle for pulling out the inner water tank 31, and can also be used as a stop for the water suction pipe 10 and the nozzle 1 when storing to prevent exposure; finally, the dust cover 13 is covered on the end of the outer water tank 32.

[0045] When storing, first remove the nozzle 1 and put it into the storage cavity 6 set inside the water flosser body 2, and at the same time bend the water suction tube 10 and put it into the inside of the water flosser body 2; secondly, push the water flosser body 2 or the inner water tank 31 so that the water flosser body 2 slides into the inner water tank 31, at this time, the convex buckle 42 inside the inner water tank is engaged with the upper buckle 441 of the convex buckle 44 outside the main shell; again, turn the water flosser body 2 and the inner water tank 31 upside down and install them into the outer water tank 32; finally, cover the dust cover 13 at the end of the outer water tank 32 to complete the storage of the entire water flosser.

[0046] The multi-layer water tank water irrigator can be miniaturized by inverting the water tank. The residual water at the water outlet of the water irrigator can be prevented from flowing out and can be collected in the inverted water tank. At the same time, the dust cover 13 is used to cover the end of the outer water tank 32, which can effectively avoid contact with unsanitary objects and ensure that the water irrigator can be used with more confidence.

[0047] Working state 2: Use state

[0048] like Figure 5 and Figure 6 As shown, when in use, after the inner water tank 31 is pulled open, the outer water tank 32 is removed and inserted into the bottom of the inner water tank 31, and is limited by the concave groove 43 in the outer water tank and the convex buckle 41 of the inner water tank on the outer wall of the inner water tank 31.

[0049] Specifically, the oral irrigator is in the storage state before use, the nozzle 1 is inserted into the water outlet end of the oral irrigator body 2, the water tank assembly 3 is pulled open to the use state, the sealing cover 12 on the water inlet 11 is opened, water is filled into the water tank of the oral irrigator, and the switch button is pressed to start the use of the oral irrigator; after use, the nozzle 1 is taken out and the water tank assembly 3 is stored in the storage state.

[0050] A conventional water flosser is provided with a layer of water tank. In order to increase the volume of the water tank, the overall size of the water flosser is large. For the same water flosser with a 200ml water tank, the volume of the water flosser with a multi-layer water tank is only about 2 / 3 of that of the water flosser with a single-layer water tank. In addition, the storage volume of the water flosser of the utility model is small enough for easy carrying. An inner water tank 31 support plate 5 is provided at the lower end of the inner water tank 31 to play a limiting role, preventing the water nozzle of the water suction pipe 10 from being exposed when stored, and can be used as a handle to facilitate pulling out the water tank when pulled open.

[0051] The above describes the specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.

[0052] In the description of the present utility model, it should be understood that the terms "upper", "lower", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. The wording 'comprising' does not exclude the presence of elements or steps not listed in the claims. The wording 'one' or 'an' preceding an element does not exclude the presence of multiple such elements. The simple fact that certain measures are recorded in mutually different dependent claims does not indicate that a combination of these measures cannot be used for improvement. Any reference symbols in the claims should not be interpreted as limiting the scope.
