The thermocouple 6 and the ignition needle 7 are arranged at the groove 207, so that the integrated fire cover 20 also has the functions of flameout protection and ignition, and the normal use of the burner 2 can be ensured.

It should be noted that: the arrangement of the thermocouple 6, the ignition needle 7 and the groove 207 provided in the embodiments of the present disclosure is not limited to the form of the fire cover 20 of the present application, and other forms of the fire cover 20 may also be configured with the groove 207 of the present application, and the fire cover 20 in the manner of arranging the thermocouple 6 and/or the ignition needle 7 by arranging the groove 207 belongs to the alternative embodiments of the present application.

Alternatively, as shown in fig. 13 and 15, when the thermocouple 6 is positioned in the groove 207, (for convenience of distinction, the groove 207 corresponding to the thermocouple 6 is collectively referred to as a second groove 2072), the side wall of the second groove 2072 is provided with an auxiliary fire hole 2073, the auxiliary fire hole 2073 is in communication with the air mixing chamber 204, the auxiliary fire hole 2073 corresponds to the thermocouple 6, and the auxiliary fire hole 2073 is used for burning the thermocouple 6.

In this embodiment, the second groove 2072 is correspondingly provided with an auxiliary fire hole 2073, and the auxiliary fire hole 2073 can burn the thermocouple 6 all the time, so that the thermocouple 6 cannot flameout and power off, and thus the normal operation of the thermocouple 6 can be ensured.

Alternatively, as shown in fig. 15, the number of auxiliary fire holes 2073 is plural, and at least two of the plurality of auxiliary fire holes 2073 are respectively located at opposite side walls of the second recess 2072.

In this embodiment, the thermocouple 6 is located in the second recess 2072, and at least two auxiliary fire holes 2073 are located on the side wall of the second recess 2072, so that it can be further ensured that the flame of the auxiliary fire holes 2073 can burn the thermocouple 6, so as to improve the fire protection performance of the thermocouple 6.

Optionally, both the fire transfer holes 2074 and the auxiliary fire holes 2073 are in communication with the second cavity 2042.

In this embodiment, the fire transfer holes 2074 and the auxiliary fire holes 2073 are both communicated with the second cavity 2042, and the first fire holes 2051 can be understood as the main fire holes 205 because the apertures of the first fire holes 2051 are larger, when the flame of the fire cover 20 needs to be reduced, the first injector 221 can be controlled not to intake air, so that the first cavity 2041 has no fuel gas, and the first fire holes 2051 have no flame. At this time, the second injector 222 is kept supplying gas, and the second cavity 2042 contains gas, so that the second flame holes 2052 can burn, and thus a small flame mode of the flame cover 20 can be realized. In order to ensure that the thermocouple 6 still can work normally when the fire cover 20 is in the small fire mode, the fire transfer holes 2074 and the auxiliary fire holes 2073 are communicated with the second cavity 2042, so that the thermocouple 6 can be ensured to have flame all the time.

The disclosed embodiments also provide a gas stove 100 comprising the burner 2 of any of the embodiments described above.

The gas stove 100 provided in the embodiments of the present disclosure, because of including the burner 2 in any of the embodiments described above, has the beneficial effects of the burner 2 in any of the embodiments described above, and will not be described in detail herein.

Alternatively, as shown in fig. 23, the accommodating chamber 10 of the gas cooker 100 has a movable port 102, the movable port 102 is communicated with the accommodating chamber 10, and when the burner 2 moves to the first position, the fire hole 205 is located above the movable port 102, so as to realize the combustion of the fire cover 20. The gas range 100 further includes a bushing 11, and the bushing 11 is disposed at an edge of the movable port 102 and protrudes from an upper surface of the housing 1. When the burner 2 is lowered to the second position, the lower surface of the top wall 201 of the fire cover 20 abuts against the liner 11.

In this embodiment, when the burner 2 is lowered to the second position, the lower surface of the top wall 201 of the fire cover 20 abuts against the liner 11, so that the liner 11 can reduce the adsorption force between the lower surface of the top wall 201 of the fire cover 20 and the upper surface of the housing 1, thereby reducing the jamming in the lifting process of the burner 2, and reducing the heat transfer of the fire cover 20 to the housing 1. In addition, the lining 11 protrudes from the upper surface of the casing 1, so that water on the upper surface of the fire cover 20 or water on the upper surface of the casing 1 can be prevented from flowing into the accommodating cavity 10, and the lining 11 plays a certain role in blocking.

It should be noted that: the movable opening 102 in the embodiment of the present disclosure is the opening 101 or the first avoiding through hole 401, so that the bushing 11 may be disposed on the housing 1 or the liquid bearing disc 40. Specifically, when the inner diameter of the first avoidance through hole 401 is larger than the inner diameter of the opening 101, the bushing 11 is disposed at the opening 101, and when the inner diameter of the first avoidance through hole 401 is smaller than or equal to the inner diameter of the opening 101, the bushing 11 is disposed at the first avoidance through hole 401.

Alternatively, as shown in fig. 24, the bush 11 is configured with a catching groove 111, the notch of the catching groove 111 faces the edge of the movable port 102, and the catching groove 111 is fitted with the edge of the movable port 102 so that the bush 11 is mounted at the edge of the movable port 102. In this embodiment, the clamping groove 111 is convenient for the bushing 11 to be stably installed at the edge of the movable opening 102, so that the bushing 11 is convenient to install and detach, and further the gas stove 100 is convenient to clean.

Alternatively, the bush 11 is annular, and the bush 11 is matched with the top wall 201 so that the top wall 201 can abut against the bush 11 in the circumferential direction thereof.

In this embodiment, the annular bush 11 enables the bush 11 to abut against the top wall 201 in the circumferential direction, and also prevents the flow of soup or water into the accommodating chamber 10 in the circumferential direction of the movable port 102.

Optionally, the lower wall of the top wall 201 is recessed upwardly to form a recess (hereinafter referred to as a third recess 2012 for ease of distinction), and the upper end of the liner 11 is located within the third recess 2012 when the burner 2 is moved to the second position.

In this embodiment, the third groove 2012 is configured to avoid the liner 11, so that when the combustor 2 moves to the second position, the liner 11 can abut against the top wall 201 of the third groove 2012, so as to avoid jamming caused by lifting of the combustor 2.

Alternatively, when the burner 2 moves to the second position, the lower wall surface of the outer side wall 202 of the third recess 2012 abuts against the upper wall surface of the housing 1. When the burner 2 moves to the second position, the outer side wall 202 of the third groove 2012 abuts against the housing 1, so that the soup or water can be further prevented from flowing into the third groove 2012, and the soup or water can be further prevented from flowing into the accommodating cavity 10.

The above description and the drawings illustrate embodiments of the disclosure sufficiently to enable those skilled in the art to practice them. Other embodiments may include structural and other modifications. The embodiments represent only possible variations. Individual components and functions are optional unless explicitly required, and the sequence of operations may vary. Portions and features of some embodiments may be included in, or substituted for, those of others.
