Description

Technical Field

[0001] The utility model relates to the technical field of production and manufacturing of tooth washer, in particular to an F-shaped nozzle of a tooth washer and a cold-bonding pressure-maintaining fixture. Background Art

[0002] As we all know, a dental irrigator is an electric tool used to clean teeth and oral cavity, also commonly known as an oral irrigator or water flosser. It uses high-pressure water flow and bubbles to remove residual food, bacteria and dirt on the surface of teeth and between teeth, providing a deep cleaning and comfortable experience for the oral cavity. Its structure generally consists of a water tank, a power cord, a handheld spray gun and a nozzle.

[0003] At present, most of the existing nozzles are conical and have a single water outlet, so when cleaning teeth, only one side of the teeth can be cleaned, which is not conducive to efficient cleaning. At the same time, in order to avoid hard collisions with gums or teeth, the nozzle mouth is generally set up with soft colloids, and the establishment of soft colloids relies on cold glue bonding during the assembly of the product. After bonding, it needs to be grasped by manpower for a certain period of time before the assembly of the nozzle can be completed. However, this often brings inconvenience to production, wastes human resources, and is not conducive to efficient production. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide an F-shaped nozzle of a tooth washer and a cold-bonding pressure-maintaining fixture.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An F-shaped nozzle for a tooth washer comprises a soft rubber nozzle and a nozzle tube, wherein a water inlet is arranged at one end of the nozzle tube and a connection end for connecting to a main body of the tooth washer is formed, and a water outlet is arranged at the other end of the nozzle tube and a receiving end is formed, and a first annular groove is arranged at the periphery of the water outlet of the receiving end, and an outer skirt and an inner skirt are formed at the receiving end by opening the first annular groove, and a U-shaped opening is arranged at one end of the soft rubber nozzle and a bonding opening is arranged at the other end, and water spray holes are arranged at the inner end surfaces of the two top ends of the U-shaped opening, and a water inlet is arranged at the bonding opening, and the water inlet and the water spray hole are connected, and a boss opening capable of accommodating the inner skirt is arranged on the inner wall of the water inlet, and a second annular groove capable of accommodating the outer skirt is arranged at the periphery of the water inlet.

[0007] Preferably, the U-shaped opening is gradually raised at the location of the water spray hole.

[0008] A cold bonding and pressure-maintaining jig for bonding the above-mentioned F-type nozzle of a toothbrush, comprising a bottom mold and a top mold, wherein the bottom mold is provided with at least one placement position for satisfying the inverted placement of the soft rubber nozzle, and the shape of the placement position corresponds to the U-shaped opening; the upper end of the top mold is connected to an external pressure device, and the lower end of the top mold is provided with pressure grooves corresponding in number to the placement position, and the shape of the pressure grooves corresponds to the back side of the receiving end.

[0009] Preferably, guide holes and guide columns are provided between the bottom mold and the top mold.

[0010] Due to the adoption of the above scheme, the utility model sets the water outlet port into a U-shaped mouth, and sets water spray holes on both sides of the U-shaped mouth, so that it can spray water in both directions, satisfying the need to rinse the inner and outer sides of the teeth at the same time, thereby improving the efficiency of tooth cleaning. At the same time, a boss mouth and multiple annular grooves are set at the joint between the soft glue nozzle and the nozzle pipe, which can not only meet the assembly limit, but also be used to accommodate glue for subsequent bonding.

[0020] like Figures 1 to 6 As shown, the present embodiment provides an F-type nozzle for a tooth washer, comprising a soft rubber nozzle 1 and a nozzle tube 2, wherein one end of the nozzle tube 2 is provided with a water inlet 3 and is formed with a connection end 4 for connecting to a main body of the tooth washer, and the other end of the nozzle tube 2 is provided with a water outlet 5 and is formed with a receiving end 6, wherein the receiving end 6 is provided with a first annular groove 7 around the water outlet 5, and an outer skirt 9 and an inner skirt 8 are formed at the receiving end 6 by opening the first annular groove 7, The soft glue nozzle 1 is provided with a U-shaped mouth 10 at one end and a bonding mouth 11 at the other end. The inner end surfaces of the two top ends of the U-shaped mouth 10 are provided with water spray holes 12. The bonding mouth 11 is provided with a water inlet hole 13. The water inlet hole 13 and the water spray hole 12 are connected. A boss mouth 14 that can accommodate the inner skirt 8 is provided on the inner wall of the water inlet hole 13. The bonding mouth 11 is located around the water inlet hole 13 and is provided with a second annular groove 15 that can accommodate the outer skirt 8.

[0021] In this embodiment, the water outlet port is set as a U-shaped mouth 10, and water spray holes 12 are arranged on both sides of the U-shaped mouth 10, so that water can be sprayed in two directions, so that the inner and outer sides of the teeth can be rinsed at the same time, thereby improving the tooth cleaning efficiency. At the same time, a boss mouth 14 and a plurality of annular grooves are set at the joint between the soft glue nozzle 1 and the nozzle tube 2, which can not only meet the assembly limit, but also be used to contain glue for subsequent bonding.

[0022] Furthermore, the U-shaped opening 10 of the present embodiment is gradually raised at the water spray hole 12. The establishment of the raised portion allows the water sprayed from the water spray hole 12 to better enter the gaps between teeth, thereby facilitating cleaning of teeth.

[0023] A cold bonding pressure-maintaining jig for bonding the above-mentioned F-type nozzle of the toothbrush comprises a bottom mold 101 and a top mold 102. The bottom mold 101 is provided with at least one placement position 103 for satisfying the inverted placement of the soft rubber nozzle 1, and the shape of the placement position 103 corresponds to the U-shaped mouth 10. The upper end of the top mold 102 is connected to an external pressure device, and the lower end of the top mold 102 is provided with counter-pressure grooves 104 corresponding in number to the placement position 103, and the shape of the counter-pressure grooves 104 corresponds to the back side of the receiving end 6. When bonding is performed, the soft glue nozzle 1 is first turned upside down, with the U-shaped mouth 10 as the clamping mouth, and inserted into the placement position 103. At this time, the bonding mouth 11 of the soft glue nozzle 1 faces upward, and a proper amount of glue is dripped into the second annular groove 15. Then the receiving end 6 of the water spray pipe 2 faces the bonding mouth 11 and is pressed into the bonding mouth 11, so that the inner skirt 8 is placed in the boss mouth 14, and the outer skirt 9 is placed in the second annular groove 15. After the assembly is completed, it can be driven as an external pressure device to push the top mold 102 down, press it on the bottom mold 101, and maintain it for a certain period of time to complete the bonding operation.

[0024] Furthermore, in order to ensure the stability of the up and down movement between the bottom mold 101 and the top mold 102, a guide hole 105 and a guide column 106 are provided between the bottom mold 101 and the top mold 102 in this embodiment. The guide hole 105 and the guide column 106 can play a role in movement guidance to avoid position deviation.

[0025] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
