DETAILED DESCRIPTION

[0022] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only the parts related to the present application, rather than all structures, are shown in the accompanying drawings.

[0023] Embodiment 1

[0024] Figure 1 A schematic diagram of a gas stove nozzle assembly provided in Example 1 of the present application, as shown in FIG. Figure 1 As shown, the gas stove nozzle assembly provided in this embodiment includes: a nozzle seat 100 and an electric control valve 200;

[0025] The nozzle seat 100 is provided with an air inlet 101, an air outlet 102 and a valve body installation cavity 103;

[0026] The air inlet 101 is connected to the outlet of the mechanical cock of the gas stove, the air outlet 102 is connected to the burner ejector pipe of the gas stove, and the inlet of the mechanical cock of the gas stove is connected to the gas pipeline;

[0027] The electric control valve 200 is installed in the valve body installation cavity 103 and is used to cut off or connect the air inlet 101 and the air outlet 102 .

[0028] In this embodiment, the gas transmission path is: the gas in the gas pipeline is transmitted to the inlet of the mechanical stopcock through the inlet connected to the mechanical stopcock inlet of the gas stove. When the mechanical stopcock is turned to a certain angle, the gas is transmitted to the air inlet 101 of the nozzle seat 100 through the outlet of the mechanical stopcock. When the electric control valve 200 installed in the valve body mounting cavity 103 of the nozzle seat 100 is opened, the gas is transmitted to the air outlet 102 of the nozzle seat 100 and enters the connected burner injector pipe.

[0029] It should be noted that Figure 1 The gas stove nozzle assembly shown is a double nozzle structure, which is adapted to the structure of the double burner ejector tube of the gas stove commonly used at present. In this embodiment, the combination of components that can realize the function of a single nozzle in the double nozzle structure is called a gas stove nozzle assembly. Therefore, this embodiment only describes one gas stove nozzle assembly in the double nozzle structure, and the specific structure of the other gas stove nozzle assembly is the same as that of the double nozzle structure, which will not be described in detail.

[0030] In addition, in this embodiment, the nozzle seats 100 in the two gas stove nozzle assemblies can be an integrally formed structure.

[0031] like Figure 1As shown, the nozzle seat 100 is provided with two air inlets 101, two air outlets 102 and two valve body installation cavities 103, wherein the two air inlets 101 do not affect each other, the two air outlets 102 do not affect each other, and the two valve body installation cavities 103 do not affect each other.

[0032] The air inlet 101, the air outlet 102 and the valve body installation cavity 103 on one side form a set of nozzle gas paths, and the air inlet 101, the air outlet 102 and the valve body installation cavity 103 on the other side form a set of nozzle gas paths. In one nozzle gas path, the gas enters through the air inlet 101 in the nozzle gas path, passes through the valve body installation cavity 103 in the nozzle gas path, and is output from the air outlet 102 in the nozzle gas path.

[0033] It should be noted that, in order to facilitate the connection between the nozzle holder 100 and the burner ejector pipe, a nozzle is provided between the nozzle holder 100 and the burner ejector pipe, such as Figure 1 As shown, one end of the nozzle is provided with a threaded structure, through which it is fastened to the air outlet 102 of the nozzle holder 100, and the other end of the nozzle is provided with a snap-fit ​​structure, through which it is fastened to the burner ejector tube.

[0034] Similarly, for the dual-nozzle structure, in this embodiment, each group of nozzle gas paths is provided with a nozzle.

[0035] Of course, the nozzle holder 100 may also be a single nozzle structure. Under the structure of the double burner ejector tube of the commonly used gas stove, using two nozzle holders 100 can also have the same function. Figure 2 , Figure 2 This is a schematic structural diagram of a nozzle holder with a single nozzle structure provided in the first embodiment of the present application. The nozzle holder 100 with a single nozzle structure has only one air inlet 101 , one air outlet 102 and one valve body installation cavity 103 .

[0036] Its fuel gas transmission gas path is the same as the aforementioned groups of nozzle gas paths, and will not be repeated here.

[0037] In order to better meet the user's usage habits, the electric control valve 200 can be set to a normally open electric control valve 200, that is, an electric control valve 200 that is in an open state under normal circumstances. When the user switches from a traditional gas stove to a gas stove equipped with the gas stove nozzle assembly of this embodiment, this method can default to loading the gas stove nozzle assembly of this embodiment as a traditional mechanical plug valve control method.

[0038] Compared with the electric control valve 200, the traditional mechanical plug valve is more reliable and safer. The gas stove is normally controlled by the traditional mechanical plug valve, which can improve the safety of the gas stove to a certain extent.

[0039] Since the electric control valve 200 is a normally open electric control valve 200, when the user uses it, when the intelligent operation is not performed, the traditional mechanical stopcock valve can be used for control, thereby meeting the user's traditional gas stove usage needs. When intelligent control is required, the user opens the mechanical stopcock to the maximum, and the user selects the relevant intelligent control program according to the needs, and the opening of the electric control valve 200 can be controlled according to the relevant intelligent control program to realize intelligent control.

[0040] In this embodiment, by setting a valve body installation cavity 103 on the nozzle seat 100 and installing the electric control valve 200 in the valve body installation cavity 103, the electric control valve 200 can cut off or connect the air inlet 101 and the air outlet 102 of the nozzle seat 100; in addition, the air inlet 101 is connected to the outlet of the mechanical stopcock of the gas stove, the air outlet 102 is connected to one end of the nozzle, and the other end of the nozzle is connected to the burner ejection pipe of the gas stove. Based on the above structure, when it is necessary to manually control the firepower through the mechanical stopcock, the electric control valve 200 can be set to an open state, so that the air intake can be controlled through the mechanical stopcock. When intelligent control is required, the mechanical stopcock can be opened to the maximum, and the air intake can be controlled through the electric control valve 200. The purpose of realizing both intelligent control and retaining the mechanical stopcock is achieved, and the flexibility of use is improved.

[0041] In this embodiment, various types of valve bodies can be used. For details, please refer to Figure 3 , Figure 3 A schematic diagram of the structure of a cut-off electric control valve provided in the first embodiment of the present application. The electric control valve 200 of this embodiment may include a valve body 201, and the type of the valve body 201 may be a cut-off valve type. In addition, the electric control valve 200 also includes an electric control element 202 and a mounting plate 203; the mounting plate 203 is sleeved between the electric control element 202 and the valve body 201, the valve body 201 is disposed in the valve body mounting cavity 103, and the mounting plate 203 is fixed on the nozzle seat 100.

[0042] The electric control element 202 refers to an element that can control the opening of the valve body 201 according to the control signal, and the mounting plate 203 is an element used to fix the electric control valve 200 to the nozzle seat 100, wherein a plurality of threaded mounting holes can be arranged on the nozzle seat 100, and the mounting plate 203 is provided with through holes at corresponding positions, and threaded fixing parts such as bolts are passed through the through holes and screwed into the threaded mounting holes, thereby fastening the mounting plate 203 to the nozzle seat 100.

[0043] Since the mounting plate 203 is sleeved between the electric control element 202 and the valve body 201, after the mounting plate 203 is fastened to the nozzle seat 100, the valve body 201 will be fastened in the valve body mounting cavity 103. Of course, the sleeve here is a fixed sleeve, which can be fixed by welding or by snapping.

[0044] It should be noted that the valve core movement direction of the cut-off electric control valve 200 in this embodiment is perpendicular to the direction of the mounting plate 203 toward the valve body mounting cavity 103. The structure of the valve body mounting cavity 103 can be found in Figure 4 , Figure 4 A schematic structural diagram of a valve body installation cavity provided in Example 1 of the present application.

[0045] like Figure 4 As shown, the valve body installation cavity 103 is provided with an installation cavity inlet 1031 along the valve core movement direction of the valve body, and the installation cavity inlet 1031 is connected with the air inlet 101; the inner wall of the valve body installation cavity 103 is provided with an installation cavity outlet 1032 along the vertical direction of the valve core movement direction of the valve body, and the installation cavity outlet 1032 is connected with the air outlet 102; when the electric control valve is in a closed state, the stop end of the valve body blocks the installation cavity inlet 1031, and the gas is cut off from entering the valve body installation cavity 103.

[0046] It should be noted that the valve core movement direction can be as follows Figure 4 As shown in the dotted line with an arrow, the direction indicated by the arrow is the closing direction of the valve core, and opening is the opposite direction of the dotted arrow.

[0047] In order to further improve the airtightness of the valve body when it is closed, please refer to Figure 5 , Figure 5 The cross-sectional diagram of a cut-off electric control valve in a closed state provided in the first embodiment of the present application. Figure 5 As shown, the installation cavity inlet 1031 is provided with a circle of raised walls 2012 ; the cut-off end 2011 of the valve body is in a plate shape, used to cover the raised walls 2012 .

[0048] The cut-off end 2011 of the valve body abuts against the raised wall 2012 to block the installation cavity inlet 1031 , thereby preventing the gas from entering the installation cavity through the installation cavity inlet 1031 .

[0049] In order to improve the airtightness of the plugging, a rubber pad can be set on the contact surface between the cut-off end 2011 and the raised wall 2012. During sealing, since the rubber pad is relatively soft, it will deform under the pressure of the cut-off end 2011 and the raised wall 2012, thereby filling the small gap that may exist on the contact surface between the cut-off end 2011 and the raised wall 2012 when the rubber pad is not set, thereby improving the airtightness of the plugging.

[0050] Of course, the valve body 201 of the embodiment can also be a ball valve type. Figure 6 , Figure 6 A schematic diagram of the structure of another valve body installation cavity provided in the first embodiment of the present application is shown in FIG. Figure 6As shown, the inner wall of the valve body installation cavity 103 is provided with an installation cavity inlet 1031 and an installation cavity outlet 1032; the installation cavity inlet 1031 and the installation cavity outlet 1032 are arranged opposite to each other, the installation cavity inlet 1031 is connected with the air inlet 101, and the installation cavity outlet 1032 is connected with the air outlet 102; one end of the valve body is connected with the installation cavity inlet 1031, and the other end of the valve body 201 is connected with the installation cavity outlet 1032.

[0051] In order to improve the airtightness of the ball valve type valve body, during installation, one end of the valve body is connected to the installation cavity inlet 1031 through a threaded structure, and the other end of the valve body is connected to the installation cavity outlet 1032 through a threaded structure.
