Description

Technical Field

[0001] The utility model particularly relates to an ultrasonic welding structure for borderless lighting of a bathroom heater panel. Background Art

[0002] A bathroom heater is the preferred heating device for many families when bathing (also known as a multi-function heater in the industry). The current mainstream air-heated bathroom heater integrates heating, lighting, ventilation, blowing, air guidance, and air purification. It features a built-in electric overheat protector that automatically shuts off when the temperature reaches a certain level. Installed on the ceiling of the bathroom, the bathroom heater takes up no space and offers a great decorative effect.

[0003] There is also a diffuser panel on the bathroom heater, which is fixed to the surface of the bathroom heater by pasting. Due to the pasting method, the adhesive overflows onto the diffuser surface or the outer edge of the bathroom heater during the hot-melt process, resulting in an unsightly overall appearance and a waste of adhesive.

[0022] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0023] Reference below Figures 1 to 5 The ultrasonic welding structure for borderless lighting of the bathroom heater panel according to the embodiment of the present invention is described, including a chassis 3 and a diffuser plate 2. The diffuser plate 2 is installed on the chassis 3. An LED light strip 4 is installed in the chassis 3. The top surface of the frame of the chassis 3 is provided with an adhesive portion 303. The side of the adhesive portion 303 is provided with an adhesive groove. The top end of the adhesive portion 303 is adhered to the bottom surface of the diffuser plate 2 by ultrasonic hot melt.

[0024] This structure provides a glue groove on the side of the adhesive portion 303. During the ultrasonic heat-melting process of the adhesive portion 303, the glue groove receives the melted adhesive from the adhesive portion 303, thereby preventing the adhesive from overflowing and improving the overall aesthetics. In addition, after the glue groove receives the adhesive, the contact area between the adhesive and the bottom surface of the diffuser plate 2 is increased, thereby improving the adhesion.

[0025] The LED light strips 4 are connected to a DC ballast, which supplies power to the LED light strips 4. Five LED light strips 4 are arranged, and the five LED light strips 4 are evenly distributed on the inner bottom surface of the chassis 3. When the five LED light strips 4 are powered, the LED light strips 4 illuminate the diffuser plate 2, and the diffuser plate 2 evenly distributes the light.

[0026] The adhesive grooves in this structure are divided into a first adhesive groove 301 and a second adhesive groove 302. The first adhesive groove 301 and the second adhesive groove 302 are located on either side of the adhesive portion 303. The first adhesive groove 301 and the second adhesive groove 302 increase the receiving capacity. The first adhesive groove 301 and the second adhesive groove 302 are integrally formed with the chassis 3. The lower end of the adhesive portion 303 is bonded to the top surface of the frame of the chassis 3.

[0027] like Figure 4 As shown, the glue groove of this structure is square. Figure 5 As shown, the glue groove of this structure is in a concave arc shape.

[0028] The chassis 3 of this structure is further provided with a side panel 1. The chassis 3 and the side panel 1 of this structure are formed as one piece, thereby improving the overall rigidity.

[0029] The adhesive portion 303 of this structure is square in shape and can be adapted to the chassis 3. In this structure, the chassis 3 and the diffuser plate 2 are preferably square in shape, so that the chassis 3 can be better fixed on the bottom surface of the diffuser plate 2 and is not prone to leakage.

[0030] The inner wall surface of the chassis 3 of this structure is arranged obliquely, which does not affect the light emission of the LED light strip 4.

[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
