[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application 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.

[0031] like Figures 1 to 9 As shown, an embodiment of the present invention provides a shell for a water flosser. The water flosser has a power output axis L, and the shell for the water flosser includes a shell 10 and a prefabricated partition member 20. Among them, the shell 10 is a cylindrical structure with an installation channel, the cylindrical structure extends along the power output axis L and has a first end 11 and a second end 12 arranged opposite to each other; the prefabricated partition component 20 is located in the shell 10, the prefabricated partition component 20 extends from the first end 11 to the second end 12, and the prefabricated partition component 20 is constructed to divide the interior of the shell 10 into a movement cavity 13 and a water inlet cavity 14; wherein the prefabricated partition component 20 has a first side portion 21, a second side portion 22 and a connecting wall portion 23 for connecting the first side portion 21 and the second side portion 22, the first side portion 21 is arranged toward the movement cavity 13, the second side portion 22 is arranged toward the water inlet cavity 14, at least part of the connecting wall portion 23 is engaged with the shell 10, wherein, along the circumference of the water inlet cavity 14, a circular arc transition connection is formed between the second side portion 22 and the inner wall of the shell 10.

[0032] In the above technical scheme, by setting a prefabricated partition component 20, and the prefabricated partition component 20 is engaged with the shell 10, the prefabricated partition component 20 can be embedded in the shell 10 to realize the connection between the prefabricated partition component 20 and the shell 10. In this way, it is possible to avoid integrally forming the prefabricated partition component 20 with the shell 10, so that the overall wall thickness of the prefabricated partition component 20 can be set thicker to improve the strength of the prefabricated partition component 20, thereby making the prefabricated partition component 20 resistant to deformation and not easy to be stretched open to achieve a stable and reliable sealing effect; the position where the prefabricated partition component 20 is connected to the shell 10 is set as a rounded corner, that is, the corner of the water inlet cavity 14 can be set as a rounded corner, so as to avoid the problem of dirt hiding and difficulty in cleaning due to the setting of sharp corners.

[0033] Furthermore, compared with the prior art arrangement in which the shell and the partition structure are integrally formed, under the same layout, this embodiment embeds the prefabricated partition component 20 into the shell 10, which not only increases the wall thickness of the prefabricated partition component 20 to increase the strength of the prefabricated partition component 20 and makes the prefabricated partition component 20 less likely to deform, that is, the waterproof reliability is higher, but also facilitates the setting of rounded corners to achieve a more beautiful, less likely to hide dirt, and easier to clean effect.

[0034] It should be noted that, in the embodiment of the present invention, the joint setting of the prefabricated partition component 20 and the shell 10 refers to: in the pre-embedded injection molding, the connection method between the pre-embedded part (prefabricated partition component 20) and the injection molding material (shell 10); specifically, the prefabricated partition component 20 is an embedded part (embedded part or nested part), and the prefabricated partition component 20 can be injection molded first, and then the prefabricated partition component 20 is placed in the shell mold for nested injection molding to achieve the joint between the prefabricated partition component 20 and the shell 10.

[0035] It should be noted that, in the embodiment of the present invention, the arc transition connection formed between the second side portion 22 and the inner wall of the shell 10 means that the second side portion 22 and the shell 10 are transitionally connected via a fillet 56, that is, the arc transition connection is used to form a fillet.

[0036] like Figure 1 and Figure 2 As shown, in an embodiment of the present invention, the housing for the oral irrigator further includes: a first cover body 30; a mounting member 40, which is arranged at the second end 12 and is integrally formed with the shell 10, and the mounting member 40 is engaged with a portion of the connecting wall portion 23, and the first cover body 30 is sealed and connected to the shell 10 and the mounting member 40, respectively.

[0037] In the above technical solution, since the dividing line (joint position) between the prefabricated partition component 20 and the shell 10 extending along the power output axis L has a certain protrusion or depression, by additionally providing a mounting component 40 integrally formed with the shell 10, the mounting component 40 can be sealed and connected to the first cover body 30. In this way, the joint position (protrusion or depression) between the prefabricated partition component 20 and the shell 10 can be avoided from contacting the first cover body 30 and affecting the sealing of the outer shell.

[0038] Specifically, in an embodiment of the present invention, a groove is provided on the outer periphery of the first cover body 30, and an O-ring is provided in the groove. The first cover body 30 realizes sealing cooperation with the shell 10 and the mounting member 40 respectively through the O-ring. Among them, by providing the mounting member 40, it is possible to avoid the presence of a boundary line between the prefabricated partition member 20 and the shell 10 extending along the power output axis L at a position that cooperates with the circumferential outer side of the O-ring, thereby avoiding the bulge or depression generated at the boundary line between the prefabricated partition member 20 and the shell 10 from affecting the circumferential sealing of the O-ring.

[0039] like Figure 2 As shown, in an embodiment of the present invention, the mounting component 40 is located in the cylindrical structure, and the mounting component 40 includes: a mounting body 41; a shielding body 42, which is connected to the second end 12, the shielding body 42 is connected to the mounting body 41 and is arranged at an angle, the shielding body 42 is located on the side of the mounting body 41 away from the movement cavity 13, the side of the mounting body 41 away from the movement cavity 13 is engaged with the connecting wall portion 23, and the side of the shielding body 42 facing the prefabricated partition component 20 is engaged with the connecting wall portion 23.

[0040] In the above technical solution, the shielding body 42 is located on the side of the installation body 41 away from the movement cavity 13, the shielding body 42 is integrally formed with the shell 10, and the side of the shielding body 42 facing the first end 11 is engaged with the connecting wall portion 23. In this way, the prefabricated partition component 20 can be prevented from passing through the second end 12 of the shell 10 along the power output axis L, thereby preventing the joint position (dividing line) between the prefabricated partition component 20 and the shell 10 from being exposed, so as to avoid unnecessary lines on the bottom appearance of the outer shell, thereby increasing the aesthetics of the outer shell.

[0041] Furthermore, by making the installation body 41 and the shielding body 42 both be connected to the connecting wall portion 23 , the connection area between the prefabricated partition member 20 and the installation member 40 can be increased, thereby improving the installation stability of the prefabricated partition member 20 .

[0042] like Figure 4As shown, in the embodiment of the present invention, the mounting body 41 is an arc-shaped plate, and the arc-shaped plate is arched toward the direction of the water inlet cavity 14. In this way, a smooth transition connection between the mounting body 41 and the housing 10 can be achieved, avoiding the problem of easy dirt hiding due to a sharp angle between the mounting body 41 and the housing 10.

[0043] In order to ensure that the surface of the housing 10 does not shrink during injection molding, the mounting body 41 needs to be designed with a thinner wall thickness at the connection with the housing 10. Therefore, it is also easy to form a sharp angle between the mounting body 41 and the housing 10. In this way, the position of the sharp angle is difficult to clean, and the thinner wall thickness will cause the mounting body 41 to have low strength and be easy to deform. Therefore, if Figure 6 and Figure 7 As shown, in an embodiment of the present invention, the prefabricated partition component 20 is embedded in the injection mold, and the space enclosed by the prefabricated partition component 20 and the injection mold is used to fill the injection material to form the shell 10 and the installation component 40.

[0044] Through the above-mentioned arrangement, the sharp angle formed between the mounting body 41 and the shell 10 is filled with embedded parts (prefabricated partition member 20). In this way, not only can the problem of difficulty in cleaning due to dirt hidden in the sharp angle be avoided, but also the strength of the mounting member 40 can be increased, and the prefabricated partition member 20 does not need to reduce the wall thickness due to being integrally formed with the shell 10; and the shell 10 and the mounting member 40 can be integrally formed, thereby avoiding the appearance of a dividing line extending along the power output axis L between the mounting member 40 and the shell 10, and then the sealing of the O-ring can be ensured when the mounting member 40 and the shell 10 are in contact and sealed with the O-ring.

[0045] like Fig. 9 As shown, in the embodiment of the present invention, the portion of the connecting wall portion 23 away from the first end is recessed toward the direction of the water inlet cavity 14 to form a recessed space 51 , and the recessed space 51 cooperates with the mounting component 40 .

[0046] Through the above-mentioned arrangement, the recessed space 51 can avoid the mounting component 40 to prevent the mounting component 40 from protruding relative to the prefabricated partition component 20, thereby avoiding damaging the aesthetics of the outer shell, and by making the recessed space 51 cooperate with the mounting component 40, the contact area between the prefabricated partition component 20 and the mounting component 40 can be increased, thereby increasing the joining stability between the prefabricated partition component 20 and the mounting component 40.

[0047] It should be noted that, in the embodiment of the present invention, the bottom wall of the recessed space 51 forms a portion of the connecting wall portion 23 disposed toward the movement cavity 13 .

[0048] It should be noted that, in the embodiment of the present invention, the injection molding material used to form the housing 10 is filled into the recessed space 51 to form the mounting member 40 after injection molding.

[0049] Specifically, Fig. 9 As shown, in an embodiment of the present invention, a first protrusion 511 is provided on one or both sides of the recessed space 51 along a direction perpendicular to the power output axis L, the first protrusion 511 is connected to the first side portion 21, and the surface of the first protrusion 511 facing the movement cavity 13 is flush with the surface of the first side portion 21 facing the movement cavity 13.

[0050] Specifically, Fig. 9 As shown, in the embodiment of the present invention, along the direction set at an angle to the power output axis L, a second protrusion 512 is provided between the two sides of the recessed space 51, the second protrusion 512 is connected to the first side portion 21, the surface of the second protrusion 512 facing the movement cavity 13 is flush with the surface of the first side portion 21 facing the movement cavity 13, and the first protrusion 511 and the second protrusion 512 are arranged at intervals; the recessed space 51 surrounded by the first protrusion 511, the second protrusion 512 and the first side portion 21 When the injection mold is used to inject the mounting component 40, the protrusion on the injection mold can be squeezed on the mounting component 40 during injection molding (i.e., the injection material between the first protrusion 511 and the second protrusion 512), which can prevent the injection mold from directly squeezing the prefabricated partition component 20, thereby preventing the prefabricated partition component 20 from cracking or deforming; and the protrusion on the injection mold can press the mounting component 40 during injection molding onto the prefabricated partition component 20, so that the beer sleeve can be made more stable through extrusion.

[0051] During the beer fitting, if the prefabricated partition component 20 is directly embedded for injection molding without reserving the recessed space 51 for injection molding to form the mounting component 40 (the part combined with the O-ring), when the combined part between the prefabricated partition component 20 and the shell 10 is located at the position matching with the O-ring, the two materials (the prefabricated partition component 20 and the shell 10) are inconsistent, and it is difficult to ensure the flatness and airtight consistency of the position matching with the O-ring, thus resulting in a low degree of sealing with the O-ring. Therefore, specifically, in the embodiment of the present invention, along the power output axis L, the second protrusion 512 is arranged flush with the first protrusion 511 to ensure that when the injection mold is filled and injected, the mounting member 40 formed after injection molding is of the same material and meets the height (width) combined with the O-ring, and when the movement assembly 4 is installed in the movement cavity 13 of the shell, and then the first cover body 30 containing the O-ring is assembled, the inner surface of the movement cavity 13 (the integrally formed housing 10 and the mounting member 40) and the outer side surface of the first cover body 30 can respectively squeeze the O-ring, and the consistency of the cavity material (the integrally formed housing 10 and the mounting member 40) can be maintained to squeeze the O-ring, so that the sealing effect is good, and the movement cavity 13 can form an IPX7 level sealing and isolation effect;

[0052] like Fig. 9 As shown, in the embodiment of the present invention, a limiting member 52 is provided on the connecting wall portion 23, a limiting groove is provided on the mounting component 40, and the limiting member 52 cooperates with the limiting groove.

[0053] Through the above-mentioned arrangement, during the injection molding process of the shell 10, the prefabricated partition component 20 is first placed in the injection mold, and the limit member 52 will abut against the inner wall of the cavity of the injection mold. In this way, when the injection material used to form the shell 10 is filled into the cavity of the injection mold, the limit member 52 can make the part of the prefabricated partition component 20 where the limit member 52 is provided difficult to move or deform, thereby ensuring that the installation component 40 formed after injection molding can be stably combined with the limit member 52, and then the prefabricated partition component 20 can be more stably embedded in the installation component 40.

[0054] like Figure 4 and Figure 5 As shown, in the embodiment of the present invention, a reinforcing member 53 is provided on the side where the first side portion 21 and / or the side where the second side portion 22 is located. The reinforcing member 53 is integrally formed with the shell 10 and is embedded in the prefabricated partition member 20 .

[0055] Through the above arrangement, at the boundary between the shell 10 and the prefabricated partition member 20, the reinforcing member 53 integrally formed with the shell 10 and the prefabricated partition member 20 are interlaced with each other, thereby improving the bonding strength.

[0056] Preferably, in the embodiment of the present invention, a reinforcing member 53 is disposed on both the side where the first side portion 21 and the side where the second side portion 22 are located.

[0057] Preferably, in the embodiment of the present invention, reinforcing members 53 are provided at both ends of the first side portion 21 along the circumference of the power output axis, and reinforcing members 53 are provided at both ends of the second side portion 22 along the circumference of the power output axis.

[0058] like Figures 4 to 9 As shown, in the embodiment of the present invention, the inner wall surface of the movement cavity 13 is an arc surface arranged around the center line of the movement cavity 13, the arc surface of the movement cavity 13 is formed on the first side portion 21 and the housing 10, the inner wall surface of the water inlet cavity 14 is an arc surface arranged around the center line of the water inlet cavity 14, the arc surface of the water inlet cavity 14 is formed on the housing 10 and the second side portion 22, and the water inlet cavity 14 and the movement cavity 13 are arranged side by side. In this way, the sharp angle can be avoided, thereby avoiding the problem of dirt hiding and difficulty in cleaning.

[0059] Preferably, in the embodiment of the present invention, the arc surface 55 of the first side portion 21 is smoothly connected to the inner wall of the housing 10 , and the arc surface 55 of the first side portion 21 is recessed toward the side where the water inlet cavity 14 is located.

[0060] Preferably, in the embodiment of the present invention, along the circumference of the power output axis, the arc surface 55 of the second side portion 22 includes a first arc surface, a second arc surface and a third arc surface connected in sequence, the first arc surface and the third arc surface are both recessed toward the direction of the movement cavity 13, the second arc surface is recessed toward the side where the water inlet cavity 14 is located, and the first arc surface and the third arc surface are respectively smoothly connected to the surfaces of the two reinforcing members 53 at both ends of the first side portion 21. In this way, a rounded angle can be used instead of a sharp angle, thereby avoiding the problem of dirt hiding and difficulty in cleaning.

[0061] like Figure 3 As shown, in an embodiment of the present invention, the housing for the water flosser further includes a second cover body 2 , which is disposed on the water inlet cavity 14 , and the second cover body 2 is sealed with the inner wall of the water inlet cavity 14 .

[0062] like Figure 8 and Fig. 9 As shown, in an embodiment of the present invention, the prefabricated partition component 20 includes a mounting tube 24 and a partition plate 25 connected to the mounting tube 24, the mounting tube 24 is embedded in the first end 11, the prefabricated partition component 20 extends from the mounting tube 24 to the second end 12, and the partition plate 25 is embedded in the circumferential inner wall of the shell 10, the first side portion 21 and the second side portion 22 are formed on the partition plate 25, and the connecting wall portion 23 is formed on the mounting tube 24 and the partition plate 25.

[0063] Through the above-mentioned arrangement, not only the stability of the prefabricated partition component 20 embedded in the shell 10 can be increased, but also a partial water inlet cavity 14 can be formed inside the mounting tube 24, so that the second cover body 2 can be sealed with the mounting tube 24. In this way, it can be avoided that the joint position (protrusion or depression) between the prefabricated partition component 20 and the shell 10 contacts the second cover body 2 and affects the sealing of the outer shell.

[0064] In one embodiment, the prefabricated partition component 20 may also only include a partition plate, as long as the partition between the water inlet cavity 14 and the movement cavity 13 is achieved.

[0065] Preferably, in the embodiment of the present invention, the mounting tube 24 and the partition plate 25 are integrally formed.

[0066] like Figure 1 and Figure 3 As shown, an embodiment of the present invention provides a water flosser, comprising: a water tank 6; the above-mentioned water flosser housing, sealed and connected to the water tank 6, and the water inlet cavity 14 is connected to the interior of the water tank 6; a movement assembly 4, arranged in the movement cavity 13; a nozzle 1, penetrated by the water flosser housing, one end of the nozzle 1 is connected to the movement assembly 4, and the other end of the nozzle 1 extends out of the movement cavity 13.

[0067] Specifically, in an embodiment of the present invention, the nozzle 1 can spray out a thin stream of water when working; by setting a water inlet cavity, water can be added to the water tank 6 through the water inlet cavity 14, and when the nozzle 1 is not needed, the nozzle 1 can be stored in the water inlet cavity 14.

[0068] Specifically, in an embodiment of the present invention, the core assembly 4 includes structures such as a motor, a battery, a pump body and a PCB. The core assembly can convert the water in the water tank into a high-pressure water flow and deliver it to the nozzle 1.

In addition, when the movement assembly 4 is installed in the movement cavity 13 of the outer shell, and then the first cover 30 including the O-ring is assembled, the inner surface of the movement cavity 13 and the outer surface of the first cover 30 squeeze the O-ring respectively, so that the movement cavity 13 forms an IPX7 level sealing and isolation effect; at this time, the movement cavity 13 of the outer shell and the O-ring are matched around the periphery to withstand the outward expansion force of the O-ring.

[0071] The above-mentioned punch has all the advantages of the above-mentioned shell for the water flosser, which will not be repeated here.

[0072] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: by setting a prefabricated partition component, and the prefabricated partition component is engaged with the shell, the prefabricated partition component can be embedded in the shell to realize the connection between the prefabricated partition component and the shell.
