DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] See also Figure 1-Figure 3 An embodiment of the present application provides a water flosser 1 , which may include a shell assembly 10 and a movement assembly 20 .

[0041] Specifically, the shell component 10 can be made of plastic material, for example, including but not limited to hard plastic, such as polyethylene, polyester and thermoplastic plastic. The shell component 10 can also be made of metal material, such as aluminum alloy. The embodiment of the present application does not specifically limit the material used for the shell component 10.

[0042] See also Figure 2-Figure 4Further, the shell assembly 10 may include a main shell 11 and a cover body 12, wherein the main shell 11 and the cover body 12 may jointly define a accommodating cavity 10a, the main shell 11 has a length direction AA and a circumference perpendicular to the length direction AA, and a mounting opening 11a may be opened on a side wall of the main shell 11 in the circumferential direction, and the cover body 12 is used to cover the mounting opening 11a.

[0043] It should be noted that the main shell 11 and the cover body 12 can be separately set, and the main shell 11 and the cover body 12 are separately set means that the main shell 11 and the cover body 12 are not an integrally formed structure, but the main shell 11 and the cover body 12 can be connected by snap-fitting, screwing, etc., which is not limited in this embodiment of the present application.

[0044] The movement component 20 can be installed in the accommodating cavity 10a through the installation opening 11a, that is, when the water jet 1 is assembled, since the main shell 11 has a mounting opening 11a on a side wall in the circumferential direction, the movement component 20 can be installed into the accommodating cavity 10a from the mounting opening 11a, so as to realize that the movement component 20 is loaded into the accommodating cavity 10a. Compared with the prior art in which the movement component 20 is loaded into the accommodating cavity 10a from the opening opened in the length direction AA of the shell component 10, the embodiment of the present application opens a mounting opening 11a on a side wall in the circumferential direction of the main shell 11, so that the movement component 20 can be loaded into the accommodating cavity 10a from the mounting opening 11a, and the movement component 20 is loaded into the accommodating cavity 10a from a side wall in the circumferential direction of the main shell 11, that is, the movement component 20 is loaded into the accommodating cavity 10a from the mounting opening The installation stroke of the movement assembly 11a into the accommodating cavity 10a is smaller than the installation stroke of the movement assembly 20 through the opening along the length direction AA of the shell assembly 10 into the accommodating cavity 10a, thereby making the installation stroke of the movement assembly 20 from the installation opening 11a into the accommodating cavity 10a shorter. Furthermore, due to the setting of the installation opening, the installation process of the movement assembly 20 into the accommodating cavity 10a can be visually observed, thereby avoiding the movement assembly 20 being blocked by the main shell assembly 10, so that the positioning accuracy of the movement assembly 20 into the accommodating cavity 10a is higher. That is, when the movement assembly 20 is installed into the accommodating cavity 10a from the installation opening 11a, the technician does not need to repeatedly adjust the movement assembly 20, thereby facilitating the assembly of the movement assembly 20 and the main shell assembly 10. In this way, the assembly efficiency of the oral irrigator 1 can be improved.

[0045] See also Figure 4-Figure 5In some embodiments, the movement assembly 20 has a first alignment connector 21, and a second alignment connector 111 is provided on the inner wall of the main shell 11. It can be understood that when the movement assembly 20 is loaded into the accommodating cavity 10a, the first alignment connector 21 and the second alignment connector 111 can be aligned and matched, and the first alignment connector 21 and the second alignment connector 111 are connected to each other, so that the movement assembly 20 is fixed in the accommodating cavity 10a, that is, the movement assembly 20 is loaded into the accommodating cavity 10a from the installation opening 11a, and the movement assembly 20 is fixed on the inner wall of the main shell 11, thereby improving the stability of the assembly between the movement assembly 20 and the main shell 11.

[0046] It should be noted that the embodiment of the present application does not specifically limit the number of the first alignment connectors 21 and the second alignment connectors 111 . For example, the number of the first alignment connectors 21 and the second alignment connectors 111 may be two or four.

[0047] See also Figure 4-Figure 6 Further, in some embodiments, the movement assembly 20 may include a bracket 22 .

[0048] Specifically, the first alignment connector 21 may include a first through hole arranged on the bracket 22, the second alignment connector 111 may include a first stud arranged on the inner wall of the main shell 11, and the shell assembly 10 also includes a first screw connector 13, and the first screw connector 13 may be a screw. When the movement assembly 20 is loaded into the accommodating cavity 10a, the first screw connector 13 can be passed through the first through hole so that the first screw connector 13 and the first stud are threadedly matched, thereby fixing the bracket 22 to the main shell 11, that is, the movement assembly 20 can be fixed to the inner wall of the main shell 11 through the first screw connector 13, so that the movement assembly 20 can be stably and quickly connected to the main shell 11, which facilitates the assembly of the movement assembly 20 and the main shell 11, thereby improving the assembly efficiency of the water flosser 1.

[0049] See also Figure 4-Figure 5 In some embodiments, the main shell 11 is provided with a second stud 112, and the cover body 12 has a second through hole 121. It can be understood that the second stud 112 is provided on the inner wall of the main shell 11, and the cover body 12 is provided with a second through hole 121 on the side facing the main shell 11, and the shell assembly 10 also includes a second screw connection 14, and the second screw connection 14 can be a screw, wherein the second screw connection 14 can pass through the second through hole 121 and threadedly cooperate with the second stud 112, that is, after the movement assembly 20 is loaded into the accommodating cavity 10a from the installation opening 11a, the second through hole 121 is connected with the second stud 112 through the second screw connection 14, so that the cover body 12 is fixed to the main shell 11, so that the movement assembly 20 can be protected.

[0050] Please continue reading Figure 4-Figure 5 Furthermore, in some embodiments, the shell assembly 10 also includes a sealing plug 15, which may be cylindrical. The sealing plug 15 is disposed in the second through hole 121, and the sealing plug 15 may be located on the side of the second screw connection 14 away from the second stud 112. When the user cleans the oral irrigator 1, since the sealing plug 15 is disposed in the second through hole 121, and the sealing plug 15 is located on the side of the second screw connection 14 away from the second stud 112, external water can be prevented from entering the accommodating chamber 10a from the second through hole 121, thereby preventing the movement assembly 20 from being damaged by water ingress. In this way, the sealing between the main shell 11 and the cover body 12 is improved, and the service life of the movement assembly 20 is extended.

[0051] See also Figure 4 In some embodiments, a partition 113 is provided in the main shell 11, and the partition 113 can separate the accommodating chamber 10a into a first chamber 10b and a second chamber 10c.

[0052] Specifically, in the length direction AA of the oral irrigator 1, the accommodating chamber 10a is divided into a first chamber 10b and a second chamber 10c by a partition 113, wherein the movement assembly 20 is arranged in the second chamber 10c. When the number of the second studs 112 is multiple, part of the second studs 112 are arranged in the first chamber 10b, and the cover body 12 is provided with a second through hole 121 corresponding to the part of the second studs 112 in the second chamber 10c. The second screw connection 14 can pass through the second through hole 121 and threadedly cooperate with the second stud 112, so as to fix the cover body 12 on the main shell 11. In this way, the stability of the assembly of the cover body 12 and the main shell 11 is improved.

[0053] Furthermore, when external water enters the accommodating chamber 10a through the second through hole 121, since the partition 113 divides the accommodating chamber 10a into a first chamber 10b and a second chamber 10c, and the movement assembly 20 is located in the second chamber 10c, damage to the circuit in the movement assembly 20 can be avoided, thereby extending the service life of the movement assembly 20.

[0054] See also Figure 4-Figure 5 In some embodiments, the housing assembly 10 further includes a sealing ring 16. The sealing ring 16 is an accessory for sealing. The sealing ring 16 is mostly made of rubber material, and has the characteristics of corrosion resistance, tear resistance and elasticity.

[0055] When the movement assembly 20 is installed into the accommodating cavity 10a through the installation opening 11a, the cover body 12 can cover the installation opening 11a. Since the cover body 12 and the main shell 11 can be separately arranged, there may be a gap between the cover body 12 and the main shell 11, and the existence of the gap can allow external water to enter the accommodating cavity 10a, thereby affecting the circuit of the movement assembly 20. By providing a sealing ring 16, and the sealing ring 16 is clamped between the main shell 11 and the cover body 12, so that the sealing ring 16 can seal the gap between the main shell 11 and the cover body 12, thereby preventing external water from entering the accommodating cavity 10a. In this way, the sealing between the cover body 12 and the main shell 11 is improved.

[0056] Please continue reading Figure 4-Figure 5 In some embodiments, the side where the installation opening 11a is located is the open side of the main shell 11, and the movement assembly 20 is installed into the accommodating cavity 10a from the open side of the main shell 11, wherein the housing assembly 10 may further include a guide member 17, and the two side walls of the main shell 11 adjacent to the open side are respectively a first side wall 114 and a second side wall 115,

[0057] The guide member 17 can be arranged on the inner wall surface of at least one of the first side wall 114 and the second side wall 115, that is, the guide member 17 can be arranged on the inner wall surface of the first side wall 114, or on the inner wall surface of the second side wall 115, or on the inner wall surfaces of the first side wall 114 and the second side wall 115 at the same time, and the embodiment of the present application does not make any specific limitation on this.

[0058] Furthermore, the number of guide members 17 can be multiple. For example, multiple guide members 17 can be arranged at intervals along the length direction AA of the oral irrigator 1. When the movement assembly 20 is loaded into the accommodating cavity 10a from the installation opening 11a, the guide member 17 can be used to guide the movement assembly 20 from the installation opening 11a into the accommodating cavity 10a. In this way, the assembly efficiency of the movement assembly 20 into the accommodating cavity 10a is improved.

[0059] See also Figure 2-Figure 3In some embodiments, the main shell 11 also includes a top wall 116 and a bottom wall 117 that are relatively arranged. It can be understood that the oral irrigator 1 may include a nozzle 30, wherein the top wall 116 is close to the nozzle 30, and the bottom wall 117 is far away from the nozzle 30, and the top wall 116 is connected to the first side wall 114 and the second side wall 115, and the bottom wall 117 is connected to the first side wall 114 and the second side wall 115. When the cover body 12 is covered on the installation opening 11a, the cover body 12 is not only clamped between the bottom wall 117 and the top wall 116, but also between the first side wall 114 and the second side wall 115. That is, the cover body 12 needs to be clamped by the bottom wall 117, the top wall 116, the first side wall 114 and the second side wall 115 of the main shell 11, so as to improve the sealing between the main shell 11 and the cover body 12.

[0060] See also Figure 7 In some embodiments, the main shell 11 also includes a third side wall 118, and the third side wall 118 is arranged opposite to the open side of the main shell 11. The oral irrigator 1 also includes an interactive component 40, which can be used to interact with the user, and the interactive component 40 is arranged on the third side wall 118, that is, the third side wall 118 is arranged opposite to the mounting opening 11a. When the interactive component 40 needs to be assembled, since the third side wall 118 is arranged opposite to the mounting opening 11a, it is convenient to install the interactive component 40 from the mounting opening 11a to the third side wall 118, so that the integrity of the oral irrigator 1 is stronger, thereby improving the assembly efficiency of the interactive component 40 into the main shell 11.

[0061] Please continue reading Figure 7 Further, in some embodiments, since the interactive component 40 can be used to interact with the user, the interactive component 40 may include a base 41 and a light-transmitting panel 42, or the interactive component 40 may include a base 41 and a button cap 43, or the interactive component 40 may include a base 41, a light-transmitting panel 42 and a button cap 43, and the embodiments of the present application do not specifically limit this.

[0062] Exemplarily, when the interactive component 40 includes a base 41 and a light-transmitting panel 42, the base 41 can be arranged in a rectangular shape and have a mounting hole 41a. The light-transmitting panel 42 can be used to display the current power information of the oral irrigator 1, and can also display the current working status of the oral irrigator 1, etc., wherein the light-transmitting panel 42 can be formed in the mounting hole 41a through a secondary injection molding process, so that the user can observe the information displayed by the oral irrigator 1 conveniently.

[0063] For example, when the interactive component 40 includes a base 41 and a button cap 43, the user can start, stop, and switch the working mode of the water flosser 1 by pressing the button cap 43, wherein the water flosser 1 can have working modes such as whitening, cleaning, and care, which are not specifically limited in this application. The base 41 has a mounting hole 41a, and the button cap 43 can be formed in the mounting hole 41a by a secondary injection molding process. In this way, on the one hand, it is convenient for the user to operate the button cap 43, and on the other hand, it can prevent the button cap 43 from becoming loose due to long-term operation by the user.

[0064] See also Figure 4 In some embodiments, the top wall 116 is connected to the first side wall 114, the second side wall 115 and the third side wall 118, and the bottom wall 117 is also connected to the first side wall 114, the second side wall 115 and the third side wall 118, and the top wall 116, the bottom wall 117, the first side wall 114, the second side wall 115 and the third side wall 118 are integrally formed, so that the main shell 11 can be easily injection molded.

[0065] Furthermore, the top wall 116 is smoothly connected to the first side wall 114, the second side wall 115 and the third side wall 118, and the bottom wall 117 is smoothly connected to the first side wall 114, the second side wall 115 and the third side wall 118, so as to avoid scratching the user's hands due to overly sharp connections.

[0066] See also Figure 1 In some embodiments, the water flosser 1 further includes a water tank 50, which can be used to store water flossing liquid. The water tank 50 can be assembled on the cover body 12, and the water tank 50 and the shell assembly 10 are arranged side by side, and the side-by-side direction is perpendicular to the length direction AA of the shell assembly 10, that is, the water tank 50 and the shell assembly 10 are arranged side by side left and right; the water tank 50 can also be arranged along the length direction AA of the shell assembly 10, that is, the water tank 50 and the shell assembly 10 are arranged up and down, and the water tank 50 is connected to the bottom of the shell assembly 10. The present application does not specifically limit the setting position of the water tank 50.

[0067] See also Figure 2 Based on the fact that the water tank 50 is assembled on the cover body 12 and arranged side by side with the shell assembly 10, in some embodiments, the surface of the water tank 50 facing the cover body 12 can be a plane, a curved surface, or other curved surfaces, wherein the shape of the surface of the water tank 50 facing the cover body 12 is adapted to the shape of the surface of the cover body 12 facing the water tank 50, so that the water tank 50 can be easily assembled on the cover body 12.

[0068] It should be noted that the water tank 50 can be assembled on the cover body 12 by means of magnetic attraction, screw connection, and snap connection, etc., and this application does not make any specific limitation to this.

[0069] See also Figure 8-Figure 10 For example, when the water tank 50 is assembled on the cover body 12 by magnetic attraction, the water tank 50 can be provided with a first magnetic component 51, and a second magnetic component 122 is provided on the side of the cover body 12 facing the movement assembly 20, wherein the first magnetic component 51 is magnetically attracted to the second magnetic component 122, thereby realizing the assembly of the water tank 50 on the cover body 12.

[0070] Furthermore, in some embodiments, the water flosser 1 also includes an elastic member 60, which can be clamped between the second magnetic member 122 and the movement assembly 20. When the cover body 12 and the main shell 11 are assembled, the elastic member 60 can be pressed by the second magnetic member 122 and the movement assembly 20 so that the second magnetic member 122 will not easily detach from the cover body 12. In this way, the connection stability between the water tank 50 and the cover body 12 can be improved.

[0071] When the water tank 50 is connected to the bottom of the shell assembly 10 along the length direction AA of the shell assembly 10, the main shell 11 also includes a third side wall 118, and the third side wall 118 is arranged opposite to the installation opening 11a, wherein the contour line of the outer surface of the third side wall 118 can be axially symmetrical with the contour line of the outer surface of the cover body 12 about the median plane of the water flosser 1, that is, the shape of the outer surface of the third side wall 118 can be consistent with the shape of the outer surface of the cover body 12, so that the outer surface of the third side wall 118 and the outer surface of the cover body 12 are axially symmetrical with each other about the median plane of the water flosser 1, so that the user can hold the shell assembly 10 conveniently.

[0072] See also Figure 5-Figure 6 In some embodiments, the movement assembly 20 may include a water pump 23 , a water inlet pipe 24 , and an adapter 25 .

[0073] Specifically, the water inlet pipe 24 is connected and communicated with the water pump 23, the adapter 25 is communicated with the water inlet pipe 24 and fixedly connected to the main shell 11, and the cover body 12 includes an opening portion 123, the opening portion 123 and the adapter 25 are sleeved and communicated with each other. It can be understood that when the water tank 50 is assembled on the cover body 12 and arranged side by side with the shell assembly 10, the opening portion 123 can be communicated with the water tank 50. When the water flosser 1 is working, the water pump 23 can draw the water flossing liquid in the water tank 50 to the opening portion 123, and flow into the water inlet pipe 24 through the adapter 25, thereby realizing that the water pump 23 draws the water flossing liquid in the water tank 50.

[0074] See also Fig.10 Furthermore, in some embodiments, the adapter 25 has a first tubular portion 251, the opening portion 123 has a second tubular portion 1231, and the second tubular portion 1231 is installed in the first tubular portion 251, so that the connection stability between the adapter 25 and the opening portion 123 can be improved.

[0075] Furthermore, the movement assembly 20 also includes an elastic pad 26, which can be cylindrical or in other shapes. The elastic pad 26 is arranged on the outer peripheral side of the second tubular portion 1231, and the elastic member 60 is clamped between the first tubular portion 251 and the second tubular portion 1231. In this way, the sealing between the adapter 25 and the opening portion 123 can be improved.

[0076] Please continue reading Fig.10 In other embodiments, the movement assembly 20 further includes a filter 27. When the dental flushing liquid in the water tank 50 is soluble particles, the filter 27 can be used to filter the undissolved particles in the water tank 50, wherein the filter 27 is located at the connection between the first tubular portion 251 and the second tubular portion 1231, and the filter 27 is pressed between the first tubular portion 251 and the second tubular portion 1231. When the dental flushing device 1 is working, since the filter 27 is pressed between the first tubular portion 251 and the second tubular portion 1231, the undissolved particles in the dental flushing liquid can be prevented from being sucked into the water inlet pipe 24 by the water pump 23, thereby preventing the water inlet pipe 24 and the water pump 23 from being blocked.

[0077] Please continue reading Fig.10 In some other embodiments, the movement assembly 20 may further include an elastic pad 26 and a filter 27, wherein the elastic pad 26 is arranged on the outer peripheral side of the second tubular portion 1231, and the filter 27 is arranged at the connection point between the first tubular portion 251 and the second tubular portion 1231, and the filter 27 is pressed between the elastic pad 26 and the first tubular portion 251. In this way, on the one hand, the sealing between the adapter 25 and the opening portion 123 can be improved. On the other hand, when the water flosser 1 is working, since the filter 27 is pressed between the elastic pad 26 and the first tubular portion 251, it is prevented that the undissolved particles in the water flossing solution are sucked into the water inlet pipe 24 by the water pump 23. In this way, the blockage of the water inlet pipe 24 and the water pump 23 can be avoided.

[0078] Based on the fact that the main shell 11 has a partition 113, and the partition 113 can separate the accommodating chamber 10a into a first chamber 10b and a second chamber 10c, please refer to Figure 5 as well as Fig. 9 In some embodiments, the oral irrigator 1 may further include a nozzle 30 and a nozzle connector 70 .

[0079] Specifically, the nozzle 30 can be inserted into the nozzle connector 70, the nozzle connector 70 is disposed in the first chamber 10b, and the partition 113 is provided with a nozzle connector hole 113a (such as Figure 4As shown), the core assembly 20 is arranged in the second chamber 10c, wherein the nozzle connector 70 can be connected to the core assembly 20 through the nozzle connector hole 113a. When the irrigator 1 is working, the water pump 23 can suck the irrigating liquid in the water tank 50 so that the irrigating liquid can flow through the water inlet pipe 24 and then flow into the nozzle 30, and the irrigating liquid is sprayed from the nozzle 30 to the user's teeth through the water pump 23, thereby cleaning the user's teeth.

[0080] See also Fig. 9 Furthermore, the shell assembly 10 also includes a sealing gasket 18, wherein the sealing gasket 18 is arranged between the partition 113 and the cover body 12, that is, the sealing gasket 18 is clamped between the partition 113 and the cover body 12, so that the sealing performance of the first chamber 10b and the second chamber 10c can be improved.

[0081] Furthermore, the sealing gasket 18 and the sealing ring 16 may be an integral component or may be separately provided, and this embodiment of the present application does not specifically limit this.

[0082] Please continue reading Fig. 9 For example, when the sealing gasket 18 and the sealing ring 16 are an integral component, the molding of the sealing gasket 18 and the sealing ring 16 can be facilitated, and when the sealing gasket 18 and the sealing ring 16 are installed, the sealing gasket 18 and the sealing ring 16 can be directly installed between the main shell 11 and the cover body 12, without the need to install the sealing gasket 18 first and then install the sealing ring 16, thereby improving the assembly efficiency between the main shell 11 and the cover body 12, and thus improving the assembly efficiency of the oral irrigator 1.

[0083] Please continue reading Fig. 9 For example, when the sealing gasket 18 and the sealing ring 16 are separately provided, since the sealing gasket 18 and the sealing ring 16 are separately provided, when the sealing gasket 18 or the sealing ring 16 is damaged, only the damaged part needs to be replaced, thus saving the maintenance cost of the oral irrigator 1.
