Also, the description of the functions and constructions disclosed can be omitted for clarity and conciseness.

[0035] The terms and words used in the following description and claims are not limited to the literal meanings but are merely used by the inventors to enable a clear and consistent understanding of the present disclosure. Accordingly, it should be apparent to those skilled in the art that the description of various embodiments of the present disclosure is provided merely to be illustrative, not to limit the present disclosure as defined by the appended claims and their equivalents.

[0036] The terms "have", "may have", "include" or "may include" used in various embodiments of the present disclosure indicate the presence of the corresponding function, operation, element, etc. disclosed, but do not limit one or more additional functions, operations, elements, etc. In addition, it should be understood that the terms "include" or "have" used in various embodiments of the present disclosure are intended to indicate that the features, numbers, operations, elements, components, or combinations thereof described in the specification are present, but do not exclude the presence or addition of one or more other features, numbers, operations, elements, components, or combinations thereof.

[0037] It should be understood that when an element (e.g., a first element) is "connected" with another element (e.g., a second element), the element can be directly connected with the other element or there can be an intervening element (e.g., a third element) between the element and the other element.

[0038] Embodiments of the present disclosure provide a face shell assembly, such as Figure 1 and Figure 2As shown, it comprises a display box 100, a circuit board 200, a light shielding film 400 and a panel 500. The front side of the display box 100 is provided with an opening, the circuit board 200 is installed in the display box 100 through the opening, and the panel 500 is located on the front side of the display box 100 and covers the opening to protect the circuit board 200 and other components of the display box 100. The panel 500 can be made of light-transmitting materials such as glass and acrylic plate. The display 210 is fixed on the circuit board 200, and other electronic components can also be fixed on the circuit board 200, which can form a driving circuit to drive the display 100. The light shielding film 400 has a certain shielding effect on light, which can be made of semi-transparent materials, and the light shielding film 400 is tightly fixed on the back side of the panel 500. The back side of the circuit board 200 is provided with a plurality of elastic members 120, the two ends of the elastic members 120 abut against the inner wall of the circuit board 200 and the display box 100 respectively, the circuit board 200 installed in place compresses the elastic members 120, the elastic members 120 generate elastic restoring force, the elastic force of the elastic members 120 pushes the circuit board 200 to the front side, so that the display 210 on the circuit board 200 tightly abuts against the light shielding film 400 on the back side of the panel 500. Correspondingly, the position of the light shielding film 400 naturally corresponds to the position of the display 210, and the light shielding film 400 covers the light emitting surface of the display 210.

[0039] Due to the elastic force of the elastic members 120, the display 210 on the circuit board 200 tightly abuts against the light shielding film 400 on the back side of the panel 500 to reduce the distance between the display 210 and the panel 500, so that the reflection and halo phenomenon is not easy to occur, and the display effect is improved. At the same time, the light shielding film 400 of the embodiment can weaken the stray light of the display 210, especially for the white panel 500, which can significantly solve the halo problem on the panel 500, thereby further improving the display effect and user experience. The light shielding film 400 can be tea color to achieve a certain light shielding effect. The light shielding film 400 can have back glue to be pasted and fixed on the back side of the panel 500.

[0040] In some embodiments, as Figure 2 and Figure 3As shown, a plurality of fixed columns 110 extending to the front side of the display box 100 are fixed in the display box 100, and the elastic member 120 is a spring sleeved on the fixed column 110, which plays a guiding role on the spring, so that the spring can keep pushing the circuit board 200 forward after being compressed. The circuit board 200 is provided with a plurality of through holes 230 penetrating through itself and matched with the fixed columns 110, and specifically, the number, position and size of the through holes 230 are matched with the number, position and size of the fixed columns 110 respectively. The fixed columns 110 pass through the through holes 230 matched with them, and the end of the fixed column 110 is provided with a limiting member 130 for limiting the circuit board 200 from being separated from the fixed column 110, so as to install the circuit board 200 in the display box 100.

[0041] Further, the limiting member 130 is an elastic buckle which is detachably buckled on the front side of the circuit board 200. When installing the circuit board 200, the fixed column 110 is aligned with the through hole 230, and then the circuit board 200 is moved so that the fixed column 110 is inserted into the through hole 230. Since the elastic buckle can elastically deform, it can pass through the through hole 230 after deformation, and it is elastically reset when it moves to the front side of the circuit board 200 to be buckled on the front side of the circuit board 200. This structure can greatly facilitate the installation of the circuit board 200.

[0042] Further, a plurality of positioning columns 140 are fixed in the display box 100, and the circuit board 200 is provided with positioning grooves 240 matched with the positioning columns 140, and the positioning columns 140 are embedded in the positioning grooves 240, which can position the circuit board 200. When installing the circuit board 200, as long as the positioning column 140 can be embedded in the positioning groove 240, it can ensure that the fixed column 110 is aligned with the through hole 230, thereby assisting the installation of the circuit board 200 and making the installation operation more convenient.

[0043] Further, a surrounding plate 150 is arranged around the fixed column 110 in the display box 100, and the spring is arranged on the inner side of the surrounding plate 150 to limit the movement of the spring from the outside, so that it is stably sleeved on the fixed column 110.

[0044] In some embodiments, the circuit board 200 is also fixed with a key lamp 220 for lighting the corresponding key icon, and the outer side of the key lamp 220 can be sleeved with a key spring.

[0045] In some embodiments, as Figure 1 , Figure 4 and Figure 5As shown, the back side of the panel 500 is provided with a metal decorative plate 300. The metal decorative plate 300 is provided with a through hole 301 matched with the display 210, the display 210 passes through the through hole 301, and the metal decorative plate 300 surrounds the display 210. An annular area 310 is arranged on the metal decorative plate 300 around the through hole 301, and the annular area 310 is provided with a texture 311. The panel 500 is provided with a semi-transparent area 510 corresponding to the display 210 and a full-transparent area 520 corresponding to the annular area 310, and the full-transparent area 520 is also annular. The semi-transparent area 510 is semi-transparent, which can cover the display 210 without light emission, and when the display 210 emits light, the light can pass through the semi-transparent area 510. The full-transparent area 520 is full-transparent, so when the display 210 emits light, the panel 500 can not only display the light emitted by the display 210, but also directly observe the texture 311 from the outside of the panel 500, which provides special display effect and increases the texture of the light source.

[0046] Further, the panel 500 is also provided with a key display area 530 corresponding to the key light 220 to display a preset key icon. As shown in Figure 5 As shown, in the shutdown state, the key light is not lit, the display is not lit, and the texture of the metal decorative plate can be seen in the full-transparent area 520. In the standby state, the power key light in the key light is lit, the display is not lit, and the texture of the metal decorative plate can be seen in the full-transparent area 520. In the working state, the power key light in the key light is lit, the display is also lit, and the texture of the metal decorative plate can be seen in the full-transparent area 520.

[0047] In some embodiments, as shown in Figure 1 and Figure 4 As shown, both ends of the metal decorative plate 300 are provided with a plurality of glue leakage holes 320 filled with adhesive, and the metal decorative plate 300 is fixedly attached to the back side of the panel 500 by the adhesive, so that the metal decorative plate 300 is kept stable. The light shielding film 400 can cover the annular area 310 on the metal decorative plate 300. The adhesive can be silicone.

[0048] Further, the front side of the metal decorative plate 300 is also attached with double-sided adhesive tape 330, which is located outside the annular area 310 so as not to interfere with the texture 311 of the annular area 310, and the double-sided adhesive tape 330 is fixedly attached to the back side of the panel 500, thereby further enhancing the stability of the attachment of the metal decorative plate 300. At the same time, the metal decorative plate 300 and the panel 500 can be shaped before the adhesive dries, so as to avoid a large gap between the metal decorative plate 300 and the panel 500 caused by the adhesive tension.

[0049] Embodiments of the present application also provide a gas water heater, as shown in Figure 6 and Figure 7 shown, comprising a housing 600 and the face cover assembly of any of the above embodiments, and the specific description of the face cover assembly can refer to the above embodiments, which will not be repeated here. The front side of the housing 600 is provided with a mounting port, and the display box 100 is fixed at the mounting port, and the panel 500 is fixed on the front side of the housing 600. The purpose of providing the mounting port is to allow the display box 100 to be retracted backward, so that the display box 100 does not protrude from the front side of the housing 600, and the panel 500 can be tightly attached to the housing 600.

[0050] In some embodiments, the upper end of the panel 500 protrudes from the top surface of the housing 600, and the lower end of the panel 500 protrudes from the bottom surface of the housing 600; the top surface of the housing 600 is fixed with a first decorative plate 710, and the bottom surface of the housing 600 is fixed with a second decorative plate 720, and the first decorative plate 710 and the second decorative plate 720 both abut the back side of the panel 500. The first decorative plate 710 and the second decorative plate 720 can cover the gap between the panel 500 and the housing 600, so that impurities such as dust are not easy to enter the housing 600, and play a dustproof protection role. At the same time, the appearance of the product is improved, and the overall visual effect of the product is better.

[0051] In some embodiments, as shown in Figures 7-9 , the first decorative plate 710 and the second decorative plate 720 both comprise a horizontal arm 701 and two branch arms 702, the two branch arms 702 are respectively connected to both ends of the horizontal arm 701, the horizontal arm 701 abuts the panel 500, and the two branch arms 702 both extend along the width direction of the housing 600, and the horizontal arm 701 can extend along the length direction of the housing 600, whereby the first decorative plate 710 and the second decorative plate 720 both form a structure similar to the Chinese character "n", and the waterway joint and the gasway joint on the bottom surface of the housing 600 are located between the two branch arms 702 of the second decorative plate 720, which can protect the waterway joint and the gasway joint to a certain extent.

[0052] Further, the side of the first decorative plate 710 and the second decorative plate 720 that is close to the housing 600 is provided with a groove 703, and the existence of the groove 703 can reduce the material of the first decorative plate 710 and the second decorative plate 720, thereby reducing the production cost.

[0053] Still further, a plurality of reinforcing ribs 704 are arranged in the groove 703, and the reinforcing ribs 704 can strengthen the structural strength of the first decorative plate 710 and the second decorative plate 720.

[0054] In some embodiments, a plurality of positioning pins 705 are arranged in the groove 703 of the first decorative plate 710, and the top surface of the shell 600 is provided with positioning holes matched with the positioning pins 705. When the first decorative plate 710 is installed, the positioning pins 705 on the first decorative plate 710 are first inserted into the corresponding positioning holes, and then the first decorative plate 710 is fixed, so that the first decorative plate 710 can be accurately installed in place, and the first decorative plate 710 is prevented from being installed with a large gap from the panel 500, which affects the appearance. Specifically, the positioning pins 705 can be fixed on the reinforcing ribs 704.

[0055] In some embodiments, the two ends of the first decorative plate 710 and the two ends of the second decorative plate 720 are designed with rounded corners, so that the rounded corners of the first decorative plate 710 and the second decorative plate 720 can almost overlap the rounded corners of the panel 500. When the water heater is viewed from the front, the panel 500 can cover the shell 600, the first decorative plate 710 and the second decorative plate 720, so that the overall visual effect of the product is better.

[0056] In some embodiments, the first decorative plate 710 is detachably fixed on the top surface of the shell 600, and the second decorative plate 720 is detachably fixed on the bottom surface of the shell 600, so that the first decorative plate 710 and the second decorative plate 720 are convenient to install and disassemble.
