DETAILED DESCRIPTION

[0034] 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.

[0035] See also Figure 1 An embodiment of the present application provides a water flosser 1 , which may include a nozzle 10 , a host module 20 and a water tank 30 .

[0036] Specifically, the host module 20 is provided with a water outlet channel 20a (see Figure 3As shown), the nozzle 10 can be inserted into the water outlet channel 20a, so that the nozzle 10 is connected to the host module 20 and communicated with the water outlet channel 20a, and the host module 20 is connected and communicated with the water tank 30. When the irrigator 1 is working, the host module 20 can draw the irrigating liquid in the water tank 30, and transport the irrigating liquid to the water outlet channel 20a, and then spray the irrigating liquid through the nozzle 10, so as to clean the user's teeth.

[0037] The host module 20 is described in detail below.

[0038] See also Figure 1-Figure 3 The host module 20 may include a housing 21 and a movement 22 .

[0039] Specifically, the casing 21 is suitable for being held or grasped by the user so that the user can hold the oral irrigator 1, and the main structure of the casing 21 can be made of plastic material, for example, it can include but is not limited to hard plastic, such as polyethylene, polyester and other thermoplastic plastics. The main structure of the casing 21 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 main structure of the casing 21.

[0040] The housing 21 is provided with an installation cavity 21a inside, and the movement 22 is installed in the installation cavity 21a to prevent the movement 22 from being exposed to the outside of the oral irrigator 1. The housing 21 also has an open port 21b connected to the installation cavity 21a. The movement 22 includes a water pump 221, a water inlet pipe 222 and an adapter 223. The water inlet pipe 222 can be a plastic hose. The two ends of the water inlet pipe 222 are respectively connected to the water pump 221 and the adapter 223. The adapter 223 is connected to the water tank 30. When the water pump 221 is working, the water pump 221 draws the irrigating liquid in the water tank 30 so that the irrigating liquid flows through the adapter 223 and the water inlet pipe 222 in sequence, and then the irrigating liquid in the water inlet pipe 222 is pumped into the water outlet channel 20a by the water pump 221, so that the irrigating liquid in the water outlet channel 20a can flow into the nozzle 10, and under the action of the water pump 221, the irrigating liquid in the nozzle 10 is sprayed onto the user's teeth, thereby cleaning the user's teeth.

[0041] Further, at least the adapter 223 is installed in the installation cavity 21a through the open port 21b, and the adapter 223 is fixedly connected to the housing 21. It can be understood that the adapter 223 is installed in the installation cavity 21a from the open port 21b, and the water pump 221 and the water inlet pipe 222 can be installed in the installation cavity 21a from the open port 21b, or can be installed in the installation cavity 21a from other openings of the housing 21. This is not specifically limited in the present application. When the adapter 223 is installed in the installation cavity 21a from the open port 21b, since the open port 21b is provided in the housing 21 and communicates with the installation cavity 21a, the housing 21 has no obstruction to the process of installing the adapter 223 in the installation cavity 21a, so that the adapter 223 can be smoothly installed in the installation cavity 21a from the open port 21b, thereby improving the assembly efficiency.

[0042] Furthermore, when the water inlet pipe 222 is also installed into the installation cavity 21a from the open mouth 21b, since the housing 21 does not block the adapter 223, the housing 21 also does not block the water inlet pipe 222, so that the adapter 223 and the water inlet pipe 222 can be assembled easily, thereby improving the stability of the assembly of the adapter 223 and the water inlet pipe 222.

[0043] In the embodiment of the present application, an open port 21b is opened on the housing 21, so that the adapter 223 can be installed in the installation cavity 21a through the open port 21b, and the open port 21b is set to allow a larger installation space and operating space for installation between the open port 21b and the adapter 223, thereby facilitating the installation of the adapter 223 into the installation cavity 21a and connecting it to the water inlet pipe 222, thereby improving the stability of the assembly of the adapter 223 and the water inlet pipe 222, and the housing 21 has no obstruction to the process of installing the adapter 223 into the installation cavity 21a, so that the adapter 223 can be smoothly installed from the open port 21b into the installation cavity 21a, thereby improving the assembly efficiency.

[0044] It should be noted that the embodiment of the present application does not specifically limit the order in which the water pump 221 , the water inlet pipe 222 , and the adapter 223 in the movement 22 are installed into the installation cavity 21 a .

[0045] Exemplarily, a technician or a robot can complete the overall assembly of the water pump 221, the water inlet pipe 222 and the adapter 223, and then install the entire assembly consisting of the water pump 221, the water inlet pipe 222 and the adapter 223 in the installation cavity 21a. Since the water inlet pipe 222 and the adapter 223 have been assembled before being installed in the installation cavity 21a, the connection length between the adapter 223 and the water inlet pipe 222 will not be affected by the space in the installation cavity 21a, thereby reducing the redundancy of the water inlet pipe 222. In this way, the material preparation cost of the water inlet pipe 222 is saved.

[0046] Exemplarily, a technician or a robot can first install the water pump 221 and the adapter 223 in the installation cavity 21a respectively, and then install the water inlet pipe 222 into the installation cavity 21a, so that the two ends of the water inlet pipe 222 are connected to the water pump 221 and the adapter 223, thereby facilitating the connection between the water inlet pipe 222 and the water pump 221 and the adapter 223. In this way, the assembly sequence of the water pump 221, the adapter 223 and the water inlet pipe 222 can be more flexible.

[0047] See also Figure 3-Figure 5 In some embodiments, the adapter 223 is provided with a first fixing member 2231, and a second fixing member 211 is provided on the inner wall of the casing 21. It can be understood that when the adapter 223 is installed into the installation cavity 21a from the open opening 21b, the first fixing member 2231 and the second fixing member 211 can be fixedly connected so that the adapter 223 is fixed on the inner wall of the casing 21, that is, the adapter 223 can be fixedly connected to the casing 21, thereby improving the stability of the assembly between the adapter 223 and the casing 21.

[0048] It should be noted that the embodiment of the present application does not specifically limit the number of the first fixing members 2231 and the second fixing members 211 .

[0049] Furthermore, in some embodiments, the first fixing member 2231 may include a first through hole disposed on the adapter 223 , and the second fixing member 211 may include a first stud disposed on the inner wall of the housing 21 .

[0050] Specifically, the housing 21 also includes a first screw connector, which may be a screw. When the adapter 223 is installed into the installation cavity 21a from the open opening 21b, the first screw connector can be passed through the first through hole so that the first screw connector and the first stud are threadedly engaged, thereby fixing the adapter 223 to the housing 21. That is, the adapter 223 can be fixed to the inner wall of the housing 21 through the first screw connector, so that the adapter 223 can be quickly fixedly connected to the housing 21, thereby improving the assembly efficiency between the adapter 223 and the housing 21.

[0051] Furthermore, the first through hole may be a screw hole that is threadedly matched with the first screw connector. Thus, the first screw connector is threadedly matched with the first through hole and the first stud at the same time, so that the connection between the adapter 223 and the housing 21 is more stable.

[0052] Please continue reading Figure 3-Figure 5In some embodiments, the adapter 223 is provided with a first positioning member 2232, and a second positioning member 212 is provided on the inner wall of the housing 21. When the adapter 223 is assembled with the housing 21, the first positioning member 2232 is positioned and matched with the second positioning member 212 so that the adapter 223 and the housing 21 are relatively positioned to avoid the adapter 223 and the housing 21 being misaligned, thereby improving the assembly efficiency between the adapter 223 and the housing 21.

[0053] Furthermore, the adapter 223 may be provided with a first fixing member 2231 and a first positioning member 2232 at the same time, and the inner wall of the casing 21 may be provided with a second fixing member 211 and a first positioning member 2232 at the same time. In this way, when the adapter 223 is inserted into the installation cavity 21a from the open opening 21b, the first positioning member 2232 and the second positioning member 212 are first positioned and matched, so that the adapter 223 and the casing 21 are initially positioned, and then fixedly connected by the first fixing member 2231 and the second fixing member 211, and then the adapter 223 is fixedly connected to the inner wall of the casing 21. In this way, the assembly efficiency between the adapter 223 and the casing 21 is improved, and the assembly stability between the adapter 223 and the casing 21 is improved.

[0054] See also Figure 2 In some embodiments, the housing 21 may include a main housing 213 and a cover 214 that are separately provided, wherein the main housing 213 and the cover 214 may be separately provided, and the main housing 213 and the cover 214 are separately provided, which means that the main housing 213 and the cover 214 are not an integrally formed structure, but the main housing 213 and the cover 214 may be connected by means of snap connection, screw connection, etc., which is not limited in the embodiments of the present application. One side of the main housing 213 has an open opening 21b, and the cover 214 is used to cover the open opening 21b.

[0055] See also Figure 3 as well as Figure 6 Specifically, the second positioning member 212 is provided with a third fixing member 2121, and the cover body 214 is provided with a fourth fixing member 2141. It can be understood that the first positioning member 2232 provided on the adapter 223 can be a through hole. At this time, after the second positioning member 212 is positioned and matched with the first positioning member 2232, the third fixing member 2121 provided on the second positioning member 212 can pass through the first positioning member 2232, so that the third fixing member 2121 is fixedly connected with the fourth fixing member 2141, thereby realizing that the cover body 214 is covered on the open opening 21b, wherein the second positioning member 212 can be positioned and matched with the adapter 223, and can also be fixedly connected with the cover body 214, thereby improving the stability of the assembly of the main shell 213 and the cover body 214.

[0056] See also Figure 4In some implementations, the housing 21 further includes a sealing ring 215. The sealing ring 215 is an accessory for sealing. The sealing ring 215 is mostly made of rubber material, and the sealing ring 215 has the characteristics of corrosion resistance, tear resistance and elasticity.

[0057] When the adapter 223 is installed into the installation cavity 21a through the open port 21b, the cover body 214 can be used to cover the open port 21b. Since the cover body 214 and the main shell 213 can be separately provided, there may be a gap between the cover body 214 and the main shell 213, and the existence of the gap can allow external water to enter the installation cavity 21a, thereby affecting the circuit of the movement 22. By providing a sealing ring 215, and the sealing ring 215 is clamped between the main shell 213 and the cover body 214, the sealing ring 215 can seal the gap between the main shell 213 and the cover body 214, thereby preventing external water from entering the installation cavity 21a. In this way, the sealing between the cover body 214 and the main shell 213 is improved.

[0058] In some embodiments, the opening 21 b may be located on a side wall of the housing 21 in the circumferential direction, or may be located on the bottom wall of the housing 21 , which is not specifically limited in the embodiments of the present application.

[0059] See also Figure 2 For example, when the opening 21b is located on a side wall of the casing 21 in the circumferential direction, the main shell 213 and the cover body 214 can be arranged side by side, and the side-by-side direction is perpendicular to the length direction AA of the oral irrigator 1, so that the cover body 214 can cover the opening 21b on the main shell 213.

[0060] Exemplarily, when the opening 21b is located at the bottom wall of the casing 21, the main shell 213 and the cover body 214 are arranged along the length direction AA of the oral irrigator 1, that is, the cover body 214 is located at the bottom of the main shell 213, so that the cover body 214 can easily cover the opening 21b opened on the main shell 213.

[0061] See also Figure 7-Figure 9 In some embodiments, the cover 214 has an opening 2142, wherein the opening 2142 can be connected to the water tank 30, and the opening 2142 has a first tubular portion 2143, and the adapter 223 has a second tubular portion 2234, and the second tubular portion 2234 is sleeved outside the first tubular portion 2143 to achieve docking and communication between the adapter 223 and the opening 2142, thereby facilitating the dental flushing solution in the water tank 30 to flow into the adapter 223 through the opening 2142. Since the second tubular portion 2234 is sleeved outside the first tubular portion 2143, the sealing between the cover 214 and the adapter 223 and the stability of the connection between the cover 214 and the adapter 223 are improved.

[0062] See also Fig. 9 Furthermore, in some embodiments, the movement 22 also includes an elastic pad 224, which can be cylindrical or in other shapes. The elastic pad 224 is arranged on the outer peripheral side of the first tubular portion 2143, and the elastic member is clamped between the first tubular portion 2143 and the second tubular portion 2234. In this way, the sealing between the adapter 223 and the cover body 214 can be improved.

[0063] Please continue reading Fig. 9 Furthermore, in some embodiments, the movement 22 also includes a filter 225. When soluble particles exist in the dental rinse in the water tank 30, the filter 225 can be used to filter undissolved particles in the water tank 30, wherein the filter 225 is located at the connection between the first tubular portion 2143 and the second tubular portion 2234, and the filter 225 is pressed between the first tubular portion 2143 and the second tubular portion 2234. When the water pump 221 is working, since the filter 225 is pressed between the first tubular portion 2143 and the second tubular portion 2234, the undissolved particles in the dental rinse are prevented from being sucked into the water inlet pipe 222 by the water pump 221. In this way, blockage of the water inlet pipe 222 and the water pump 221 can be avoided.

[0064] Please continue reading Fig. 9 Furthermore, in some other embodiments, the movement 22 may include an elastic pad 224 and a filter 225 at the same time. The elastic pad 224 is arranged on the outer peripheral side of the first tubular portion 2143, and the filter 225 is arranged at the connection point between the first tubular portion 2143 and the second tubular portion 2234, and the filter 225 is pressed between the elastic pad 224 and the second tubular portion 2234. In this way, on the one hand, the sealing between the adapter 223 and the cover body 214 can be improved. On the other hand, when the water pump 221 is working, since the filter 225 is pressed between the elastic pad 224 and the second tubular portion 2234, it is prevented that the undissolved particles in the dental flushing solution are sucked into the water inlet pipe 222 by the water pump 221. In this way, the blockage of the water inlet pipe 222 and the water pump 221 can be avoided.

[0065] Please continue reading Fig. 9Based on the opening 2142 on the cover 214, in some embodiments, the water flosser 1 may further include a water drawing pipe 40, wherein one end of the water drawing pipe 40 is connected and communicated with the opening 2142, and the other end of the water drawing pipe 40 extends into the water tank 30, so that the water drawing pipe 40 is communicated with the water tank 30. When the water pump 221 is working, the water pump 221 can suck the water flossing liquid in the water tank 30, so that the water flossing liquid flows into the water drawing pipe 40, and due to The water drawing pipe 40 is connected with the opening 2142, so that the irrigating liquid flows from the water drawing pipe 40 into the opening 2142. The opening 2142 is connected and connected with the adapter 223, so that the irrigating liquid flows to the water inlet pipe 222 through the adapter 223. Under the action of the water pump 221, the irrigating liquid in the water inlet pipe 222 can be pumped to the water outlet channel 20a, so that the irrigating liquid is sprayed from the nozzle 10 to the user's teeth, thereby achieving cleaning of the user's teeth.

[0066] See also Figure 3 In some embodiments, when the opening 21b can be located on a side wall in the circumferential direction of the main shell 213, the side where the opening 21b is located is the open side of the main shell 213, and the cover body 214 can be used to cover the open side. The two side walls of the main shell 213 adjacent to the open side are respectively the first side wall 2131 and the second side wall 2132.

[0067] Specifically, the water inlet pipe 222 can be at least partially located between the first side wall 2131 and the water pump 221, the water inlet pipe 222 can also be at least partially located between the second side wall 2132 and the water pump 221, and the water inlet pipe 222 can also be at least partially located between the cover body 214 and the water pump 221. The embodiments of the present application do not make specific limitations on this.

[0068] Please continue reading Figure 3 Further, in some embodiments, the host module 20 further includes a clamping member 23, which is mainly used to clamp the water inlet pipe 222. The clamping member can be a clamping rib or other clamping structures, which is not specifically limited in the embodiments of the present application. A plurality of clamping members 23 can be arranged at intervals along the extension direction of the water inlet pipe 222, wherein the clamping member 23 can be arranged on at least one of the first side wall 2131, the second side wall 2132, the cover body 214 and the water pump 221, which is not specifically limited in the embodiments of the present application.

[0069] Optionally, when the water inlet pipe 222 is located between the first side wall 2131 and the water pump 221, the clamping piece 23 can be arranged on the first side wall 2131 and the water pump 221. When the water inlet pipe 222 is assembled, the water inlet pipe 222 can be clamped between the first side wall 2131 and the water pump 221, and the water inlet pipe 222 can be fixed between the first side wall 2131 and the water pump 221 by the clamping piece 23. In this way, the stability of the assembly of the water inlet pipe 222 is improved.

[0070] Optionally, when the water inlet pipe 222 is located between the cover body 214 and the water pump 221, the clamping piece 23 can be set on the cover body 214 and the water pump 221. When the water inlet pipe 222 is assembled, the water inlet pipe 222 can be clamped between the cover body 214 and the water pump 221, and the water inlet pipe 222 is fixed between the cover body 214 and the water pump 221 by the clamping piece 23. In this way, the assembly stability of the water inlet pipe 222 is improved.

[0071] See also Figure 3 as well as Fig.10 In some embodiments, the water pump 221 may have a first joint 2211, the adapter 223 may have a second joint 2233, and the two ends of the water inlet pipe 222 are respectively connected to the first joint 2211 and the second joint 2233, that is, the diameter of the first joint 2211 is smaller than the diameter of the water inlet pipe 222, and the diameter of the second joint 2233 is also smaller than the diameter of the water inlet pipe 222. In this way, when the water pump 221 is working, when the dental flushing liquid in the water tank 30 is sucked into the adapter 223, since the diameter of the second joint 2233 is smaller than the diameter of the water inlet pipe 222, the flow rate of the dental flushing liquid at the second joint 2233 is faster, so that the dental flushing liquid can flow quickly into the water inlet pipe 222.

[0072] Furthermore, since the two ends of the water inlet pipe 222 are respectively connected to the first joint 2211 and the second joint 2233, the connection between the water inlet pipe 222 and the first joint 2211 and the second joint 2233 is more stable, thereby improving the stability of the connection between the water inlet pipe 222 and the water pump 221 and the adapter 223.

[0073] Please continue reading Figure 3 as well as Fig.10 Further, the first joint 2211 can be extended toward the adapter 223, or the second joint 2233 can be extended toward the water pump 221, or the first joint 2211 can be extended toward the adapter 223 while the second joint 2233 can be extended toward the water pump 221. The embodiments of the present application do not specifically limit this.

[0074] Exemplarily, when the second connector 2233 is extended toward the water pump 221, the connecting pipeline between the water inlet pipe 222 and the second connector 2233 is shortened, thereby saving the material preparation cost of the water inlet pipe 222. At the same time, the second connector 2233 is arranged toward the water pump 221, which can facilitate the connection between the water inlet pipe 222 and the second connector 2233, thereby improving the assembly efficiency of the water inlet pipe 222 and the adapter 223.

[0075] See also Figure 2 as well as Fig.10Furthermore, in some embodiments, the first connector 2211 and the cover body 214 are located on different sides of the water pump 221, that is, the first connector 2211 and the cover body 214 can be located on adjacent sides of the water pump 221. When the water inlet pipe 222 is inserted into the installation cavity 21a from the open port 21b, since the first connector 2211 and the cover body 214 are located on different sides of the water pump 221, it is convenient for the water inlet pipe 222 and the first connector 2211 to be inserted into the installation cavity 21a from the open port 21b.

[0076] Furthermore, when part of the water inlet pipe 222 is located between the cover 214 and the water pump 221 , the cover 214 and the first joint 2211 are located on different sides of the water pump 221 , so that the cover 214 can fix the water inlet pipe 222 .
