Description

Technical Field

[0001] The invention relates to the field of tooth washer nozzle equipment, in particular to a gas-liquid mixed water dental floss nozzle. Background Art

[0002] With the development of society, people's requirements for living standards are getting higher and higher, and more and more people are beginning to pursue the quality of life. For example, people are beginning to pay attention to their dental health. Because going to a dental hospital to take care of teeth is not only expensive but also takes a long time, the water irrigator is becoming more and more popular. However, the existing water irrigators all spray water through a nozzle to impact the teeth and the oral surface. The user manually aligns the water irrigator nozzle with the teeth so that the sprayed water can clean the oral cavity. However, the current water irrigator nozzle uses a cavity formed on the inside to control the flow of water and provide a certain pressure through the water irrigator. Therefore, in the process of use, in order to achieve the purpose of cleaning, it is necessary to increase the pressure of the water flow control, and the water column formed will directly impact the gums. The penetration and impact force brought by the generation of pressure directly collide with the gums, causing the user's gums to feel pain, and there are obvious obstacles to use. Summary of the invention

[0024] See also Figure 1-4 The present invention provides a gas-liquid mixed water floss nozzle, comprising a nozzle body 11, wherein the upper end of the nozzle body 11 is bent toward one side to form an arc-shaped compression acceleration nozzle 901, and the nozzle body 11 is provided with a liquid flow channel 13 running through the nozzle body 11 from top to bottom;

[0025] An extrusion acceleration channel 14 is located at a curved portion inside the liquid circulation channel 13;

[0026] The diffusion acceleration zone 16 is located at the right end of the opening of the extrusion acceleration channel 14, and the left opening diameter of the diffusion acceleration zone 16 is larger than the right opening diameter;

[0027] The gas-liquid mixing zone 18 is located at the right opening end of the diffusion acceleration zone 16, and the 17 formed is used as a nozzle;

[0028] The air inlet 12 is located at the upper end of the compression acceleration nozzle 901 and is connected to the upper side of the right opening of the diffusion acceleration zone 16. When in use, the upper end of the liquid circulation channel 13 is provided with a curvature, and the curved part forms an arc-shaped compression acceleration nozzle 901. In order to realize that the liquid circulation channel 13 opened inside the compression acceleration nozzle 901 is formed at its curved part, the extrusion acceleration channel 14, the diffusion acceleration zone 16, and the gas-liquid mixing zone 18 are used to form a liquid flow rate pipeline. At the same time, the diffusion acceleration zone 16 is set, and the opening diameter difference of the two ends is different. The opening diameter of the end connected to the extrusion acceleration channel 14 is larger than the opening diameter connected to the left side of the gas-liquid mixing zone 18, forming a Laval nozzle. The front half of the nozzle is formed by the narrow throat 15 formed by the curved tube tending to the straight tube, and then it expands outward from small to large. The nozzle 14 is connected to the gas-liquid mixing area 18 to form an arrow body 17. When the liquid cleaning agent enters the inner side of the gas-liquid mixing area 18, it flows into the left side of the inner cavity of the gas-liquid mixing area 18 at a high speed together with the gas entering through the inner side of the air inlet 12. The flow speed of the liquid cleaning agent inside the diffusion acceleration area 16 changes due to the change of the cross-sectional area of ​​the nozzle, so that the sprayed liquid cleaning agent continuously performs accelerated motion; the air flowing into the air inlet 12 increases the gas content inside the liquid cleaning agent, and moves at a high speed. When the cleaning agent is sprayed into the oral cavity, the cleaning agent is in a gas-liquid mixed state; when impacting, the bubbles and water droplets in the cleaning agent in a gas-liquid mixed state collide with the teeth and burst, which can effectively reduce the penetration of the water column when it hits the gums, and improve the uniform pressure distribution within the regional range when the water column hits the gums. While reducing the excessive local pressure, the effect of uniform distribution of water pressure in the water column impact area is improved, thereby enhancing the cleaning effect and reducing the pain.

[0029] It is worth noting that in the present embodiment, the opening diameter of the extrusion acceleration channel 14 is smaller than the opening diameter of the gas-liquid mixing zone 18. During its production, manufacturing and use, the opening diameter of the pressurized acceleration channel 14 is reduced so that the compression rate of the liquid cleaning agent flowing inside is maximized within a certain range, so that the liquid cleaning agent flowing in the inner cavity is in a compressed flow state and enters the diffusion acceleration zone 16 to begin to diffuse. The flow rate will also increase further. At the same time, the molecular distance in the internal liquid becomes larger, so that there are more molecular distances inside to accommodate the gas entering from the inside of the air inlet 12. The gas-liquid mixing zone 18 with a larger opening diameter mixes and blends with each other, so that the amount of air inside the flowing liquid cleaning agent reaches an ideal state.

[0030] It is worth noting that in the present embodiment, the ratio of the inner cavity length of the gas-liquid mixing zone 18 to the inner cavity length of the diffusion acceleration zone 16 is A. In its use and production, when A>1, the length of the gas-liquid mixing zone 18 is greater than the length of the diffusion acceleration zone 16. By increasing the length of the gas-liquid mixing zone 18, the volume of the inner cavity is controlled, and then the mixing ratio and mixing efficiency between the gas and the liquid are controlled to ensure that the pressure generated by the sprayed gas and liquid is uniform; when A<1, the length of the gas-liquid mixing zone 18 is less than the length of the diffusion acceleration zone 16, forming a low-sensitivity atomizing nozzle; by controlling the two groups of lengths, the change of the nozzle model can be achieved, the applicable population is increased, and the scope of application is expanded.

[0031] Specifically, a nozzle 19 is provided on the right end face of the gas-liquid mixing zone 18, and the gas and liquid mixed inside the gas-liquid mixing zone 18 are sprayed out by means of the nozzle 19. In other embodiments, the opening size of the nozzle 19 is controlled to control the penetration force of the sprayed gas-liquid mixture and the coverage area of ​​the liquid after spraying.

[0032] More specifically, the lower surface of the nozzle body 11 is provided with a plurality of groups of raised connecting ring blocks 101, and a matching groove 102 is formed between two adjacent groups of the connecting ring blocks 101. The connecting ring blocks 101 used to form the matching groove 102 are used to cooperate and match with different toothbrush control bases 902. In actual production, on the basis of the existing ordinary toothbrush control base 902, corresponding connecting ring blocks 101 are produced according to different models of toothbrush control bases 902. By replacing the nozzle, the functional change of the existing water toothbrush can be realized, thereby increasing the use range and convenience of the above-mentioned gas-liquid mixed type water toothbrush nozzle.

[0033] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
