[0031] Reference is made to Figures 1-3 , Figure 1 a structural schematic diagram of a specific embodiment of a mounting base for a gas device provided by the present application; Figure 2 a structural schematic diagram of a specific embodiment of a sensor mounting assembly provided by the present application; Figure 1 a structural schematic diagram of a specific embodiment of a sensor mounting assembly provided by the present application; Figure 3 a structural schematic diagram of a specific embodiment of a sensor mounting assembly provided by the present application; Figure 2 a top view.

[0032] The present embodiment provides a mounting base 1 for a gas device, comprising a sensor mounting portion 11, one end of the sensor mounting portion 11 being an open end, an accommodation cavity 11a being formed inside the sensor mounting portion 11, and a recessed groove 11b being arranged at one end of the wall portion surrounding the accommodation cavity 11a close to the open end, the recessed groove 11b having an opening at one end close to the open end.

[0033] The present embodiment provides a mounting base 1 for a gas device, comprising a sensor mounting portion 11, an accommodation cavity 11a being formed inside the sensor mounting portion 11, and a sensor assembly 2 being arranged in the accommodation cavity 11a, a recessed groove 11b being arranged at one end of the wall portion surrounding the accommodation cavity 11a close to the open end, the recessed groove 11b having an opening at one end close to the open end, the sensor assembly 2 comprising a sensor bracket 21, the sensor bracket 21 comprising a limiting protrusion 2A, when the sensor assembly 2 is arranged in the sensor mounting portion 11, the sensor assembly 2 is arranged in the accommodation cavity 11a, the limiting protrusion 2A is inserted into the recessed groove 11b from the opening end of the recessed groove 11b, the limiting protrusion 2A and the recessed groove 11b are clamped, and the limiting installation of the sensor assembly 2 is realized.

[0034] Therefore, the present embodiment provides a mounting base 1 for a gas device, which replaces the traditional thin long rib structure with the recessed groove 11b, realizes the limiting installation of the sensor assembly 2, and significantly reduces the mold complexity and manufacturing cost; the recessed groove 11b has an opening at one end close to the open end, on the one hand, the limiting protrusion 2A is inserted into the recessed groove 11b, the limiting protrusion 2A and the recessed groove 11b are clamped, and the installation convenience of the sensor assembly 2 is improved; on the other hand, the opening direction of the recessed groove 11b is consistent with the demolding direction, in the demolding process, the mold can be separated along the opening direction more easily, the demolding process difficulty is reduced, and the production efficiency is improved.

[0035] The number of the recessed grooves 11b is not limited, for example, the number of the recessed grooves 11b can be at least one. In some embodiments of the present application, the number of the recessed grooves 11b is multiple, and the multiple recessed grooves 11b are distributed along the circumference of the accommodation cavity 11a.

[0036] As arranged above, the plurality of circumferentially distributed recessed grooves 11b can provide a plurality of fixing points, thereby enhancing the mounting stability of the sensor assembly 2 in the accommodating cavity 11a and preventing the sensor assembly 2 from being displaced due to external force during use; the plurality of circumferentially distributed recessed grooves 11b can also make the sensor assembly 2 be uniformly stressed in the circumferential direction, thereby prolonging the service life of the sensor assembly 2.

[0037] By Figure 2 and Figure 3 It can be seen that, in the embodiment, the sensor assembly 2 includes two limiting protrusions 2A, the two limiting protrusions 2A extend in opposite directions, the number of recessed grooves 11b is two, the two recessed grooves 11b are oppositely arranged, and the limiting protrusions 2A are correspondingly clamped in the recessed grooves 11b. In this way, while ensuring the positioning accuracy of the sensor assembly 2, the structure of the sensor mounting portion 11 and the limiting protrusions 2A is simplified, the processing difficulty is reduced, the production cost is reduced, and the production efficiency is improved.

[0038] As shown in Figure 1 and Figure 3 , the mounting base 1 for the gas equipment in the embodiment further includes a component mounting portion 12 for assembling components such as gas valves and controllers, and the component mounting portion 12 is provided with a wire harness groove 12a for accommodating the sensor wire harness 22.

[0039] In order to facilitate the sensor wire harness 22 to enter the wire harness groove 12a, the mounting position of the sensor assembly 2 needs to ensure that the sensor wire harness 22 extends in the direction close to the wire harness groove 12a. Based on this, in some embodiments of the present application, the sensor mounting portion 11 is a non-rotationally symmetric structure.

[0040] The non-rotationally symmetric structure refers to a geometric shape or object that does not have rotational symmetry in three-dimensional space. The sensor mounting portion 11 is a non-rotationally symmetric structure, that is, after rotating the sensor mounting portion 11 by a certain angle around an axis, the shape of the sensor mounting portion 11 will not be exactly the same as before rotation. In this way, it is ensured that the sensor assembly 2 can only be inserted in a specific way, thereby ensuring that the sensor assembly 2 can maintain consistent position and direction every time it is installed, ensuring that the sensor wire harness 22 extends in the direction close to the wire harness groove 12a every time it is installed, and improving the installation accuracy of the sensor assembly 2.

[0041] Specifically, in some embodiments of the present application, the number of recessed grooves 11b is at least two, and the widths of the at least two recessed grooves 11b are different.

[0042] As set above, due to the different widths of the recessed grooves 11b, the limiting protrusions 2A can only match the recessed grooves 11b of specific width, so that the sensor assembly 2 can only be inserted in a specific way, thereby ensuring that the sensor assembly 2 can maintain consistent position and direction each time it is installed, and ensuring that the sensor wire harness 22 extends in the direction close to the wire harness groove 12a each time it is installed, thereby improving the installation accuracy of the sensor assembly 2.

[0043] In some other embodiments of the present application, the number of the recessed grooves 11b is at least two, and the axial lengths of the at least two recessed grooves 11b are different. In this way, the sensor mounting portion 11 can also form a non-rotationally symmetrical structure.

[0044] Please continue to refer to Figures 1-3 In some embodiments of the present application, the wall portion surrounding the accommodating cavity 11a is provided with a recess 11c extending in the axial direction.

[0045] As set above, the recess 11c is provided, so that the wall portion surrounding the accommodating cavity 11a is no longer a simple flat structure, but forms a concave-convex structure similar to a reinforcing rib. This concave-convex structure can improve the bending and torsional resistance of the sensor mounting portion 11 without increasing the amount of material, thereby enhancing the strength and rigidity of the overall structure. At the same time, this concave-convex structure can also reduce the amount of material used without sacrificing strength and rigidity, thereby reducing production costs.

[0046] Among them, the number of recesses 11c provided on the wall portion surrounding the accommodating cavity 11a is not limited, such as at least one recess 11c.

[0047] In some embodiments of the present application, the number of recesses 11c is multiple, and the multiple recesses 11c are distributed along the circumference of the accommodating cavity 11a.

[0048] As set above, the multiple recesses 11c are distributed along the circumference of the accommodating cavity 11a, which helps to improve the strength and rigidity of the sensor mounting portion 11 along the circumference as a whole, thereby further improving the structural stability of the sensor mounting portion 11. At the same time, it can further reduce the amount of material used without sacrificing strength and rigidity, thereby further reducing production costs.

[0049] Please continue to refer to Figure 1 In some embodiments of the present application, the wall portion surrounding the accommodating cavity 11a includes a stepped wall 11d facing the open end of the sensor mounting portion 11, and the recess 11c extends to the stepped wall 11d at one end close to the closed end of the sensor mounting portion 11.

[0050] By Figure 1As can be seen, with the stepped wall 11d as the boundary, the portion of the sensor mounting part 11 near the open end is the first part 113. When the sensor assembly 2 is installed in the sensor mounting part 11, part of the sensor bracket 21 is located inside the first part 113 and abuts against the stepped wall 11d. The end of the recess 11c near the closed end of the sensor mounting part 11 extends to the stepped wall 11d, which helps to improve the strength and rigidity of the first part 113 along the axial direction, further improves the structural stability of the sensor mounting part 11, and thus improves the installation accuracy of the sensor assembly 2.

[0051] Please continue to refer to this. Figure 1 In some embodiments of this application, the recess 11c has an opening at one end near the opening end of the sensor mounting portion 11.

[0052] As set above, the recess 11c has an opening at one end near the opening of the sensor mounting part 11, so that the opening direction of the recess 11c is consistent with the demolding direction. During the demolding process, the mold can be separated more easily along the opening direction, reducing the demolding process difficulty and improving production efficiency.

[0053] Please continue to refer to this. Figure 2 In some embodiments of this application, the sensor mounting part 11 includes a termination end 111, which is close to the closed end of the sensor mounting part 11, and the outer peripheral wall of the termination end 111 is provided with reinforcing ribs 112.

[0054] The above-mentioned reinforcing rib 112 helps to enhance the structural strength of the termination end 111, improve the structural stability of the termination end 111, and minimize the deformation or damage of the termination end 111 after it is inserted into the water tank of the gas equipment.

[0055] This embodiment also provides a sensor mounting assembly, including a sensor assembly 2 and the aforementioned mounting base 1 for gas equipment. The sensor assembly 2 includes a limiting protrusion 2A. The sensor assembly 2 is mounted in the receiving cavity 11a, and the limiting protrusion 2A is engaged with the corresponding recessed groove 11b.

[0056] The sensor mounting assembly of this embodiment includes the aforementioned mounting base 1 for gas equipment, and therefore has the same technical effects as the aforementioned mounting base 1 for gas equipment, which will not be repeated here.

[0057] Please refer to Figure 3 , Figures 4-5 , Figure 4 for Figure 2 and Figure 3 A schematic diagram of the structure of the sensor assembly; Figure 5 for Figure 4 A schematic diagram of the sensor assembly at the second angle.

[0058] In some embodiments of this application, the sensor assembly 2 is a non-rotationally symmetric structure.

[0059] As mentioned earlier, to facilitate the insertion of the sensor harness 22 into the harness slot 12a, the installation position of the sensor assembly 2 needs to ensure that the sensor harness 22 extends towards the harness slot 12a. The sensor assembly 2 has a non-rotationally symmetric structure, ensuring that it can only be inserted in a specific manner. This guarantees that the sensor assembly 2 maintains a consistent position and orientation during each installation, ensuring that the sensor harness 22 always extends towards the harness slot 12a, thus improving the installation accuracy of the sensor assembly 2.

[0060] In some embodiments, the number of limiting protrusions 2A is at least two, and the widths of the at least two limiting protrusions 2A are different.

[0061] As set up above, due to the different widths of the limiting protrusions 2A, the limiting protrusions 2A can only match the recesses 11b of a specific width, so that the sensor assembly 2 can only be inserted in a specific way, thereby ensuring that the sensor assembly 2 can maintain a consistent position and orientation each time it is installed, and ensuring that the sensor harness 22 extends towards the harness groove 12a each time it is installed, thus improving the installation accuracy of the sensor assembly 2.

[0062] In other embodiments of this application, the number of limiting protrusions 2A is at least two, and the axial lengths of the at least two limiting protrusions 2A are different. In this way, the sensor assembly 2 can also be formed into a non-rotationally symmetric structure.

[0063] This embodiment also provides a gas-fired device, including a water tank and the aforementioned sensor mounting assembly, the sensor mounting assembly being connected to the water tank, with a portion of the sensor mounting part 11 extending into the interior of the water tank.

[0064] The gas equipment in this embodiment includes the aforementioned sensor mounting assembly, and therefore has the same technical effects as the aforementioned sensor mounting assembly, which will not be repeated here.

[0065] Gas-fired equipment includes, but is not limited to, gas water heaters and gas furnaces.

[0066] Depend on Figure 1 and Figure 2 As can be seen, in some embodiments of this application, the sensor mounting part 11 includes a threaded connection section 114, which is used to thread a connection with the hole of the water tank to realize the connection between the sensor mounting assembly and the water tank.

[0067] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
