[0034] The following combination Figures 1 to 7 , describing the embodiments of the present utility model.

[0035] According to an embodiment of the present invention, on the one hand, Figure 1 and Figure 2 As shown, a gas stove nozzle assembly is provided, comprising a nozzle seat 1 and a nozzle body 2 rotatably arranged in the nozzle seat 1 .

[0036] Furthermore, the nozzle body 2 is provided with a natural gas passage 201 arranged along a first direction and a liquefied petroleum gas passage 202 arranged along a second direction. The first and second directions are arranged at an angle. The nozzle holder 1 is provided with a gas passage 101. By rotating the nozzle body 2, the natural gas passage 201 or the liquefied petroleum gas passage 202 can be selected to communicate with the gas passage 101.

[0037] As can be seen, the gas stove nozzle assembly provided by the present embodiment comprises a rotatable nozzle body 2 disposed within a nozzle holder 1. This nozzle body 2 is provided with both a natural gas passage 201 and a liquefied petroleum gas passage 202. By rotating the nozzle body 2 according to the type of gas, either the natural gas passage 201 or the liquefied petroleum gas passage 202 of the corresponding gas type is connected to the gas passage 101. This allows for the use of both natural gas and liquefied petroleum gas, broadening the range of uses of the gas stove and providing a better user experience.

[0038] Specifically, the first direction is as follows Figure 5 As shown by arrow A in the figure, the second direction is as follows Figure 5 As shown by arrow B in FIG. The angle between the first direction and the second direction can be set as needed.

[0039] In one embodiment, Figure 2 As shown, the nozzle holder 1 is further provided with an air inlet 102, and the natural gas channel 201 and the liquefied petroleum gas channel 202 intersect and communicate with each other. When the gas channel 101 is connected to one of the natural gas channel 201 and the liquefied petroleum gas channel 202, the air inlet 102 is connected to the other of the natural gas channel 201 and the liquefied petroleum gas channel 202.

[0040] Because natural gas passage 201 and liquefied petroleum gas passage 202 are interconnected, and the portion of the passage not connected to gas passage 101 is connected to air inlet 102, air injection can be supplemented, promoting gas combustion and reducing carbon monoxide emissions. Furthermore, nozzle body 2 differs little from conventional nozzles, and thus has little impact on the performance of the gas stove.

[0041] It should be noted that the embodiment of the present invention does not limit the specific structure of the natural gas channel 201 and the liquefied petroleum gas channel 202, and any existing structure can be selected as needed. Figure 6 and Figure 7 As shown, both the natural gas channel 201 and the LPG channel 202 can adopt a bell-end structure, and the two are connected in the middle. Because the pressure of the natural gas channel 201 is generally lower than that of the LPG channel 202, the inner diameter of the middle portion of the natural gas channel 201 is larger than that of the LPG channel 202.

[0042] In one embodiment, Figure 4As shown, the nozzle body 2 is spherical. The gas stove nozzle assembly also includes a driving member 3. The output end of the driving member 3 is connected to the nozzle body 2 to drive the nozzle body 2 to rotate. The driving member 3 can be a motor, and the output shaft of the motor is fixedly connected to the nozzle body 2 to drive the nozzle body 2 to rotate.

[0043] Specifically, the natural gas channel 201 and the liquefied petroleum gas channel 202 respectively pass through the spherical center of the nozzle body 2 and are connected at the spherical center.

[0044] Furthermore, in one embodiment, Figures 4 to 6 As shown, a mounting groove 203 is provided on the nozzle body 2, and the output end of the driving member 3 is fixed in the mounting groove 203 and is firmly connected.

[0045] Furthermore, in one embodiment, the axis of the output end of the driver 3 is perpendicular to the axis of the natural gas channel 201 and the axis of the liquefied petroleum gas channel 202. In this case, the driver 3 only needs to rotate the nozzle body 2 90 degrees clockwise or counterclockwise to switch the natural gas channel 201 or the liquefied petroleum gas channel 202 to the gas channel 101.

[0046] In one embodiment, Figure 2 As shown, the top of the nozzle holder 1 is concave to form a first accommodating groove 103 . The first accommodating groove 103 has an arc-shaped groove surface, and the nozzle body 2 is disposed in the first accommodating groove 103 .

[0047] In one embodiment, Figure 2 and Figure 3 As shown, air inlets 102 are provided on opposite sides of the nozzle holder 1 to further increase the amount of air injected and facilitate complete combustion of the gas. Opposite ends of the natural gas channel 201 or the liquefied petroleum gas channel 202 communicate with the air inlets 102 on either side. The axes of the natural gas channel 201, the liquefied petroleum gas channel 202, and the air inlets 102 on either side are coplanar. A driver 3 is provided at the bottom of the nozzle holder 1, and the output end of the driver 3 extends through the nozzle holder 1 and into the first receiving groove 103.

[0048] In one embodiment, Figure 4 As shown, the nozzle holder 1 also includes an end cover 104, which is arranged on the top of the first receiving groove 103, and a second receiving groove is provided at the bottom of the end cover 104 corresponding to the first receiving groove 103, so that the first receiving groove 103 and the second receiving groove form a receiving space for installing the nozzle body 2.

[0049] In one embodiment, Figure 2 and Figure 4As shown, a first guide ring 4 is provided between the bottom of the first receiving groove 103 and the nozzle body 2. The output end of the driving member 3 is passed through the first guide ring 4. A second guide ring 5 is provided between the bottom of the end cap 104 and the nozzle body 2. The provision of the first guide ring 4 and the second guide ring 5 facilitates the rotation of the nozzle body 2 within the nozzle holder 1, reduces wear between the nozzle holder 1 and the nozzle body 2, and increases the service life of the nozzle holder 1 and the nozzle body 2.

[0050] In addition, a sealing ring 6 is provided between the gas outlet of the gas channel 101 and the inlet of the natural gas channel 201 or the liquefied petroleum gas channel 202. The provision of the sealing ring 6 ensures a tight seal between the outlet of the gas channel 101 and the inlet of the natural gas channel 201 or the liquefied petroleum gas channel 202, thereby preventing gas leakage.

[0051] Specifically, the bottom of the first receiving groove 103 further defines a first sub-groove for accommodating the first guide ring 4, with the outer side of the first guide ring 4 abutting against the groove wall of the first sub-groove. The bottom of the second receiving groove further defines a second sub-groove for accommodating the second guide ring 5, with the outer side of the second guide ring 5 abutting against the groove wall of the second sub-groove.

[0052] When installing the nozzle body 2, first place the second guide ring 5 in the first sub-groove of the first receiving groove 103, and install the sealing ring 6 around the gas outlet of the gas channel 101. Next, place the nozzle body 2, and then place the second guide ring 5 on top of the nozzle body 2. Finally, place the end cap 104 on top of the first receiving groove 103, positioning the second guide ring 5 in the second sub-groove of the second receiving groove.

[0053] In one embodiment, Figure 1 As shown, the gas stove nozzle assembly also includes a gas detection device 7 and a controller. The gas detection device 7 and the driving member 3 are electrically connected to the controller respectively. The controller controls the driving member 3 to drive the nozzle body 2 to rotate to the corresponding position according to the gas type detected by the gas detection device 7.

[0054] Specifically, when the gas detection device 7 detects that the gas type is natural gas, the controller controls the driving member 3 to drive the nozzle body 2 to rotate, so that the natural gas channel 201 is connected to the gas channel 101, and the liquefied petroleum gas channel 202 is connected to the air inlet 102.

[0055] When the gas detection device 7 detects that the gas type is liquefied petroleum gas, the controller controls the driving member 3 to drive the nozzle body 2 to rotate, so that the liquefied petroleum gas channel 202 is connected to the gas channel 101, and the natural gas channel 201 is connected to the air inlet 102.

[0056] The gas detection device 7 automatically detects the gas type, providing more accurate results. The controller receives the gas type detected by the gas detection device 7 and controls the drive member 3 to rotate the nozzle body 2 to the corresponding position, automatically switching between the natural gas channel 201 and the liquefied petroleum gas channel 202 for convenient use.

[0057] It should be noted that the controller can be any existing controller as needed. For example, the controller can be a microcontroller (MCU), a central processing unit (CPU), an electronic control unit (ECU), or other existing controllers. Of course, other conventional controllers can also be selected as needed. This is not limited in the present embodiment.

[0058] In addition, the embodiment of the present invention does not limit the structure of the gas detection device 7. For example, the gas detection device 7 may have a conventional structure such as a gas detector, a catalytic combustion detector, etc.

[0059] The working principle of the embodiment of the utility model is as follows:

[0060] When the gas detection device 7 detects natural gas, the controller controls the driver 3 to rotate the nozzle body 2, connecting the inlet of the natural gas channel 201 to the gas channel 101 and the outlet of the natural gas channel 201 to the gas outlet of the gas stove. The inlet and outlet of the liquefied petroleum gas channel 202 are connected to the two air inlets 102, respectively.

[0061] When the gas detection device 7 detects that the gas type is liquefied petroleum gas (LPG), the controller controls the driver 3 to rotate the nozzle body 2, connecting the inlet of the LPG channel 202 to the gas channel 101 and the outlet of the LPG channel 202 to the gas outlet of the gas stove. The inlet and outlet of the natural gas channel 201 are respectively connected to the two air inlets 102.

[0062] According to an embodiment of the present invention, on the other hand, Figure 1 As shown, a gas stove is also provided, including a stove top 8 and the above-mentioned gas stove nozzle assembly. The gas stove nozzle assembly is arranged on the stove top 8. An air intake pipe 801 is provided in the stove top 8, and the air intake pipe 801 is connected to the air inlet of the gas channel 101.

[0063] The gas stove of the embodiment of the present invention is installed with the gas stove nozzle assembly. The nozzle body 2 is provided with a natural gas channel 201 and a liquefied petroleum gas channel 202 at the same time, and the nozzle body 2 can rotate in the nozzle holder 1. According to the type of gas, the nozzle body 2 is rotated to select the natural gas channel 201 or the liquefied petroleum gas channel 202 corresponding to the gas type to be connected to the gas channel 101, which can improve the use range of the gas stove and provide a better user experience.

[0064] Specifically, the cooktop 8 is provided with a flange, to which the gas burner nozzle assembly is fixed. Since the cooktop 8 is typically configured with both an inner and outer ring burner, a pair of gas burner nozzle assemblies are provided on the flange. The gas detection device 7 can be installed on the air intake duct 801 to directly detect the type of gas within the duct.

[0065] In one embodiment, the gas stove further includes a display and operating buttons, each electrically connected to the controller. After receiving the gas type detected by the gas detection device 7, the controller can display the corresponding gas type on the display for user convenience. The user can also manually control the rotation of the driving member 3 by pressing the operating button, providing convenient operation. The operating button can be a conventional structure such as a button or knob.

[0066] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The specific contents of the above-mentioned specific embodiments only express several embodiments of the present invention. Although the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
