Description

Technical Field

[0001] This application belongs to the field of oral irrigator technology and relates to an oral irrigator. Background Technology

[0002] In the process of realizing this invention, the inventors discovered that the prior art has at least the following problems: the existing water pump and battery are arranged side by side in the core of the water flosser, and the water outlet is usually directly above the water pump. Thus, the nozzle is also directly above the water pump. In order to make the water flosser smaller, the nozzle is not located at the center of the top of the body. If the nozzle is designed to be in the center, it may lead to an increase in the size of the body, which is not conducive to the miniaturization of the water flosser.

[0003] Therefore, how to provide a water flosser that does not increase the size of the device when the nozzle is adjusted to the middle of the device body has become an urgent technical problem to be solved. Utility Model Content

[0004] To overcome the problems existing in the related technology, this application aims to provide a water flosser that can adjust the nozzle to the middle of the body without increasing the size of the body.

[0005] This application is achieved through the following technical solution.

[0006] This technical solution provides a water flosser, including a body, the body being provided with a water pump, a nozzle, and a water outlet connector for connecting the water outlet of the water pump and the water inlet of the nozzle;

[0008] A connecting channel with a step-bend structure is provided between the first flow channel and the second flow channel to form an interface;

[0009] The nozzle is located at the top center of the body.

[0010] This technical solution changes the shape of the water outlet connector so that the inlet and outlet of the water outlet connector are not on the same straight line. This allows the nozzle outlet to be located at the center of the machine body even when the water pump is not located at the center of the machine body, and does not increase the size of the machine body when the nozzle outlet is located at the center of the machine body.

[0011] The present invention is further configured such that the length of the connecting channel is less than the length of the first channel and the length of the connecting channel is less than the length of the second channel.

[0025] The technical solutions in some embodiments of the present application will be described clearly and completely below in conjunction with the drawings of some embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0027] This embodiment discloses a dental flosser, such as Figures 1-4 As shown, it includes a body 100, which is equipped with a water pump 200, a nozzle 300, and a water outlet connector 1 for connecting the water outlet of the water pump 200 and the water inlet of the nozzle 300.

[0028] The water outlet connector 1 is provided with a first flow channel 2 and a second flow channel 3, and the first flow channel 2 and the second flow channel 3 are staggered.

[0029] A connecting channel 4 with a step-bend structure is provided between the first flow channel 2 and the second flow channel 3 to form an interface 5;

[0030] Nozzle 300 is located at the top center of body 1.

[0031] It should be noted that the change in the shape of the water outlet connector 1 allows the first flow channel 2 and the second flow channel 3 of the water outlet connector 1 to be staggered, so that the water outlet and the water inlet of the water outlet connector 1 are not on the same straight line. Thus, when the water pump 200 is not located at the center of the machine body, the water outlet of the nozzle 300 is located at the center of the machine body, and the machine body size is not increased when the water outlet of the nozzle 300 is located at the center of the machine body.

[0032] like Figure 1 As shown, the length of the connecting channel 4 is less than the length of the first channel 2, and the length of the connecting channel 4 is less than the length of the second channel 3.

[0033] It should be noted that the length of the connecting channel 4, the length of the first channel 2, and the length of the second channel 3 refer to the length of the water flow from the output end of the water pump 200 to the second channel 3, and then through the connecting channel 4 and the first channel 2, to the nozzle 300 where it is sprayed out. During this process, the water flows through each channel.

[0034] like Figures 1-4 As shown, the cross-sectional area of ​​the interface 5 is equal to or greater than the outlet diameter of the nozzle 300.

[0035] It should be noted that the cross-sectional dimension of the interface 5 formed by the connecting channel 4 that connects the first channel 2 and the second channel 3 will not affect the water flow rate of the water flosser, provided that it is not smaller than the water outlet diameter of the nozzle.

[0036] like Figures 1-4 As shown, the water outlet connector 1 is integrally formed.

[0037] It should be noted that using two forty-five degree elbows as the water outlet connector 1 increases the number of interfaces, affects the sealing, and requires a certain space for installation, increasing the size of the oral irrigator body. Therefore, the integrally formed water outlet connector 1 is provided to avoid these problems.

[0038] As shown in Figure 3 , it also includes a water tank and an internal power supply, and the water pump 200 is arranged side by side with the internal power supply.

[0039] As shown in Figure 3 , the water pump 200 is in communication with the water tank through a water suction pipe.

[0040] As shown in Figure 3 , a duckbill valve 6 is arranged at the air outlet of the water tank. It should be noted that the duckbill valve 6 is automatically closed, has high reliability, can control fluid flow, and can be used to balance the air pressure inside and outside the water tank.

[0041] As shown in Figure 4 , the two ends of the water outlet connector 1 are provided with grooves 8 for installing sealing rings 7 to improve the sealing performance.

[0042] It should be noted that the grooves 8 are specifically arranged on the outer side of the water outlet connector 1 near the end of the second flow channel 3, the tail end of the first flow channel 2, and the outer side of the water outlet connector 1 near the end of the first flow channel 2, so as to improve the sealing performance by arranging the sealing rings 8.

[0043] Working principle: By changing the shape of the water outlet connector 1, the first flow channel 2 and the second flow channel 3 of the water outlet connector 1 are not on the same straight line, so that the water outlet and the water inlet of the water outlet connector 1 are staggered, and thus the position of the nozzle 300 is staggered with the position of the water pump 200 in the case of arranging the water pump 200 side by side with the internal power supply of the body 1, so that the water outlet of the nozzle 300 is located in the center of the body, and in the case that the water outlet of the nozzle 300 is located in the center of the body, the cross-sectional size of the intersection interface 5 formed by the intersection flow channel 4 between the first flow channel 2 and the second flow channel 3 is not less than the water outlet hole diameter of the nozzle 300, so as not to affect the water flow rate of the oral irrigator.

[0044] The above has described the embodiments of the present application, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles, practical applications, or improvements to the technology in the market of the embodiments, or to enable other ordinary skilled persons in the art to understand the embodiments disclosed herein.
