Detailed Description

A spray head 100 for a dental appliance according to an embodiment of the present utility model is described below with reference to fig. 1-5.

As shown in fig. 1 to 5, a spray head 100 for a dental irrigator according to an embodiment of the present utility model includes a main body 1 and a brush head 2.

Specifically, the brush head 2 is provided at one end of the main body 1 in the longitudinal direction (for example, in the up-down direction in fig. 1), the main body 1 has a first flow guide passage 11 and a second flow guide passage 12 communicating with each other, and the second flow guide passage 12 is located between the brush head 2 and the first flow guide passage 11. Wherein the cross-sectional area of the second flow guiding channel 12 increases gradually from the first flow guiding channel 11 towards the brush head 2.

For example, in the example of fig. 1 to 3, the brush head 2 is connected to one end of the main body 1 in the longitudinal direction, and the other end of the main body 1 in the longitudinal direction is adapted to be connected to a housing of the dental appliance. The first and second guide channels 11 and 12 penetrate the main body 1 in the length direction of the main body 1. One end of the first diversion channel 11 is communicated with the box body of the tooth-rinsing device, the other end of the first diversion channel 11 is communicated with the second diversion channel 12, and one end of the second diversion channel 12, which is far away from the first diversion channel 11, is communicated with the brush head 2. Therefore, the fluid in the box body of the tooth washing device sequentially flows through the first diversion channel 11 and the second diversion channel 12, and then the water stored in the box body is guided out by the brush head 2 so as to clean teeth, tooth gaps and tooth sleeves.

Referring to fig. 3, the cross section of the second diversion channel 12 is circular, and the diameter of the cross section of the second diversion channel 12 gradually increases along the direction from the first diversion channel 11 to the brush head 2, at this time, the shape of the second diversion channel 12 is approximately a truncated cone, so as to form a venturi structure. The principle of the venturi structure is that when gas or liquid flows in the venturi tube, the dynamic pressure reaches a maximum value and the static pressure reaches a minimum value at the narrowest part of the tube, and the velocity of the gas (liquid) increases due to the decrease of the cross-sectional area of the tube. The entire flow is subjected to the line narrowing process at the same time, and thus the pressure is reduced at the same time, thereby creating a pressure differential that is used to measure or provide an external suction to the fluid.

Thus, when the fluid flows from the first diversion channel 11 to the second diversion channel 12, the flow speed of the fluid is high, and the pressure of the fluid is also high. When the fluid flows along the second diversion channel 12, the flow speed of the fluid is gradually reduced, and the pressure of the fluid is also gradually reduced, so that the pressure of the fluid led out of the brush head 2 is reduced, the fluid led out of the brush head 2 is softer, and when teeth, tooth gaps and tooth sleeves are cleaned, impact damage of water flow to the surfaces of the tooth sleeves can be avoided, and the use experience of a user is improved.

According to the nozzle 100 for a dental caries device according to an embodiment of the present utility model, the cross-sectional area of the second diversion channel 12 is gradually increased from the first diversion channel 11 toward the brush head 2. From this, the one end that main part 1 is close to brush head 2 forms venturi structure, makes the velocity of flow of fluid reduce gradually, and pressure reduces gradually for the fluid that leads out from brush head 2 is softer, when clean tooth, slit of tooth and facing surface, can avoid rivers to cause the impact damage to the surface of tooth and facing, has promoted user's use experience.

According to some embodiments of the utility model, referring to fig. 3, the second diversion channel 12 comprises a first channel segment 121 and a second channel segment 122, the first channel segment 121 being in communication with the second channel segment 122 and the first diversion channel 11, respectively, the cross-sectional area of the first channel segment 121 gradually increasing in the direction from the first diversion channel 11 towards the brush head 2. That is, the first channel segment 121 is in the shape of a truncated cone. The shape of the second channel section 122 can be cylindrical, and the second channel section 122 is arranged at one end of the first channel section 121 facing the brush head 2, so that when fluid flows from the first diversion channel 11 to the first channel section 121, the flow speed of the fluid in the first channel section 121 can be gradually reduced and flows into the second channel section 122, thereby avoiding impact damage of water flow on the surfaces of teeth and tooth sockets, ensuring softer flow speed of the water flow, playing a role of massaging gums and promoting gingival blood circulation. Wherein the cross-sectional area of the second channel section 122 may be the same as the largest cross-sectional area of the first channel section 121.

According to some embodiments of the utility model, referring to fig. 3, the cross-sectional area of the first diversion channel 11 gradually decreases in the direction from the first diversion channel 11 towards the brush head 2. The cross-sectional area of one end of the first diversion channel 11, which faces the second diversion channel 12, is gradually reduced, so that the pressurization and the speed acceleration of the fluid flowing through the first diversion channel 11 are facilitated, and the fluid is led out of the box body into the second diversion channel 12 rapidly.

According to some embodiments of the present utility model, referring to fig. 1 to 3, the main body 1 includes a first connection section 13 and a second connection section 14 connected to each other, and the brush head 2 is provided on the second connection section 14, and the cross-sectional area of the second connection section 14 gradually increases in a direction away from the first connection section 13. The second diversion channel 12 is formed in the second connection section 14, and the cross-sectional area of the second connection section 14 is gradually increased in the direction in which the cross-sectional area of the second diversion channel 12 is gradually increased, so that the second connection section 14 is in a horn shape. Thus, when the user uses the dental irrigator, the second connecting section 14 can shield the mouth of the user, so that the fluid is prevented from splashing outside, and meanwhile, the structural strength of the second connecting section 14 is increased, and the structural strength and the service life of the spray head 100 are further increased.

According to some embodiments of the present utility model, referring to fig. 4 and 5, the brush head 2 includes a body 21 and a plurality of bristle tufts 22. In the description of the present utility model, "plurality" means two or more. One end of the body 21 extends into the main body 1, at least one third diversion channel 211 is arranged in the body 21, the third diversion channel 211 is communicated with the second diversion channel 12, and the cross-sectional area of the body 21 gradually decreases along the direction away from the main body 1. The plurality of bristle tufts 22 are spaced apart along the circumferential direction of the body 21.

Referring to fig. 3 to 5, at least a portion of one end of the body 21 protrudes into the main body 1, increasing the connection reliability of the body 21 and the main body 1. Three third diversion channels 211 are arranged at intervals in the circumferential direction of the body 21, the third diversion channels 211 are communicated with the second diversion channel 12, and fluid in the second diversion channel 12 is led out through the third diversion channels 211 so as to clean teeth, tooth gaps and tooth sleeves. Three bristle tufts 22 are disposed at intervals from three third guide channels 211 in the circumferential direction of the body 21. When the spray head 100 is applied to the tooth washer, and the tooth washer works, water in the box body can wash the dental collar or teeth through the first diversion channel 11, the second diversion channel 12 and the third diversion channel 211, and meanwhile, the bristle cluster 22 can also clean the teeth, the slits between teeth and the tooth socket, so that the teeth can be cleaned synchronously with tooth washing, and the cleaning efficiency is improved. Thus, the third diversion channel 211 and the bristle tufts 22 combine to form a way of cleaning the oral cavity in which the flushing is integrated, which compensates for the problem of incomplete cleaning of a single flushing and a single brushing.

Wherein the cross-sectional area of the body 21 gradually decreases in a direction away from the main body 1. That is, the body 21 is in a truncated cone shape, the cross-sectional area of one end of the body 21 adjacent to the main body 1 is large, and the cross-sectional area of one end of the body 21 far away from the main body 1 is small, so that the end of the body 21 far away from the main body 1 can extend into the small position of the teeth or the dental floss, thereby improving the cleaning efficiency of the dental floss for the teeth and the dental floss. Further, each of the bristle tufts 22 includes a plurality of first bristles 221, the plurality of first bristles 221 being spaced apart in the axial direction of the body 21, each of the first bristles 221 extending obliquely in a direction away from the body 1. Referring to fig. 4, each bristle cluster 22 includes three first bristles 221, and the three first bristles 221 are uniformly spaced along the axial direction of the body 21, so that the distribution uniformity of the first bristles 221 is increased, the first bristles 221 are convenient to apply force to teeth, slits between teeth and tooth sockets, thereby fully playing the effect of the tooth cleaner, ensuring the cleaning effect, and improving the use experience of users. The first bristles 221 are inclined in a direction away from the main body 1, so that the contact area between the first bristles 221 and teeth or tooth sockets can be increased, the first bristles 221 can wrap the teeth or tooth sockets, the tooth brushing and tooth flushing effects are ensured, and meanwhile, the number of the first bristles 221 can be reduced, so that the toothbrush is convenient to process.

Still further, referring to fig. 4, the distance between the side surface of each first bristle, which is far from the body 21, and the outer circumferential surface of the body 21 gradually increases in the direction away from the main body 1. That is, each of the first bristles 221 extends in a direction away from the main body 1, and the height of the first bristles 221 is gradually increased so that the first bristles 221 can wrap around teeth and a dental band, and cleaning is more efficient.

According to some embodiments of the present utility model, the third guide channels 211 are plural, and each third guide channel 211 is disposed between two adjacent bristle tufts 22. Each bristle tuft 22 further includes a second bristle 222, the second bristle 222 is disposed at the free end of the body 21, the second bristle 222 is located between two adjacent bristle tufts 22, and a guide surface 2221 is formed on a side of the second bristle 222 adjacent to the third guide channel 211. For example, in the example of fig. 4 and 5, three second bristles 222 are provided on the body 21, each second bristle 222 being provided in the vicinity of the third flow-guiding channel 211, so that stains cleaned via the second bristles 222 are more easily washed away by the fluid. By forming the second bristle 222 with the guide surface 2221 at a side adjacent to the third guide path 211, the fluid flowing out of the third guide path 211 flows along the guide surface 2221 by the guide surface 2221, increasing the flow path of the fluid, and making the fluid flow toward the teeth or the dental floss more gently.

In some alternative embodiments, the brush head 2 is a soft gel piece. The soft rubber piece has the advantages of high thermal stability, strong weather resistance, environmental protection, no halogen, no toxicity, no smell and the like. The soft rubber piece is adopted as the brush head 2, so that the performance of the brush head 2 is prevented from being reduced after the brush head 2 is used for a long time, the service life of the spray head 100 can be prolonged, meanwhile, the soft rubber piece has toughness and rebound resilience, the gum can be effectively massaged, and the surface of a tooth socket can be prevented from being scratched.
