Detailed implementation manners

[0018] It should be noted that the following detailed description is exemplary and is intended to provide further illustration of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0019] It should be noted that the terms used herein are only for describing the specific implementation manners and are not intended to limit the exemplary implementation manners according to the present application. As used herein, unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0020] As Figures 1 - 5 shown, a high-efficiency flushing spray head for a dental irrigator includes a spray head body 110 with a water outlet channel inside. A U-shaped water outlet head 111 is provided at the upper end of the spray head body. The spray head body 110 is composed of the U-shaped water outlet head 111 and a handle 112. The U-shaped water outlet head 111 is provided with spray holes 113 at the bottom and both side walls of the middle U-shaped groove. This spray head is provided with a U-shaped water outlet head. When in use, the teeth are located in the middle of the U-shaped water outlet head, and the spray holes at three positions can spray the teeth from three different directions, achieving an efficient spraying effect, high flushing efficiency, and good flushing effect.

[0021] In this embodiment, the inner side of the U-shaped water outlet head 111 is wrapped with a U-shaped water outlet inner core 120, and the U-shaped water outlet inner core 120 is composed of a U-shaped front cover 121 and a U-shaped rear cover 122. The water spray hole is located on the U-shaped front cover, and the water spray hole is located on the inner U-shaped surface of the U-shaped front cover. The inner U-shaped surface of the U-shaped front cover can be fully exposed. Figure 1 As shown; the whole may be wrapped by the U-shaped water outlet head 111, with only three water spray holes exposed.

[0022] In this embodiment, the nozzle body is integrally injection molded and connected with the U-shaped water outlet inner core. The nozzle is divided into two parts, namely the nozzle body and the water outlet inner core. The U-shaped front cover and the U-shaped rear cover of the water outlet inner core can be pre-injected and assembled together, and then the water outlet inner core is placed in a secondary molding mold with the nozzle body. When the nozzle body is secondary injection molded, the U-shaped water outlet inner core is wrapped therein, so that the two form an integrated structure with good integrity, high strength, good sealing, long service life, beautiful appearance, and no bonding seams or welding seams.

[0023] The purpose of the additional U-shaped water outlet core 120 in the utility model is to wrap the U-shaped water outlet core in the nozzle body during the secondary injection molding, so that the nozzle forms an integrated structure with better integrity and sealing. In the specific implementation process, it is also possible not to set the U-shaped water outlet core, but to directly set the water inlet cavity inside the U-shaped water outlet head, the water spray hole is located on the inner U-shaped surface of the U-shaped water outlet head, and the nozzle body is set to a left and right half structure that is assembled by bonding or ultrasonic welding, but the overall appearance of the structure is not good and it is easy to leak.

[0024] In this embodiment, a sink groove 123 adapted to the U-shaped rear cover is provided at the rear side of the U-shaped front cover 121, a water inlet cavity 124 located in the groove is formed between the U-shaped front cover and the U-shaped rear cover, and a water inlet hole 125 connected to the upper end of the water outlet channel is provided at the lower side of the water inlet cavity. The U-shaped rear cover is embedded in the sink groove at the rear side of the U-shaped front cover 121, which can improve the stability of the assembly of the two and avoid dislocation or offset during the process of being integrally molded with the nozzle body.

[0025] In this embodiment, in order to further improve the stability of the assembly of the two, protrusions 126 are provided at both ends of the U-shaped rear cover, and grooves 127 matching with the protrusions are provided at both ends of the sink groove on the rear side of the U-shaped front cover.

[0026] In this embodiment, the front end of the water spray hole at the bottom of the trough is trumpet-shaped, and the water spray holes on the two side walls are inclined toward the opening direction of the U-shaped water outlet head.

[0027] For any of the technical solutions disclosed by the present utility model, unless otherwise stated, if it discloses a numerical range, the disclosed numerical range is a preferred numerical range. Any person skilled in the art should understand that the preferred numerical range is only the numerical values with obvious technical effects or representativeness among many implementable numerical values. Since there are too many numerical values to enumerate, the present utility model only discloses some numerical values to illustrate the technical solutions of the present utility model. Moreover, the above-listed numerical values should not constitute a limitation on the protection scope of the present utility model.

[0028] If the present utility model discloses or involves components or structural members that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connected using bolts or screws), or it can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integral structure (for example, manufactured integrally by casting process) (except where it is obviously impossible to use the integral forming process).

[0029] In addition, for any of the technical solutions disclosed by the present utility model, the terms used to represent the positional relationship or shape, unless otherwise stated, include states or shapes that are approximate, similar, or close to it.

[0030] Any component provided by the present utility model can either be assembled from multiple separate components or be a single component manufactured by an integral forming process.

[0031] The above are only the preferred embodiments of the present utility model, and do not impose other forms of limitations on the present utility model. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
