Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0027] The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise stated, the meaning of "a plurality" is two or more.

[0028] In the description of the present application, it should be noted that unless otherwise clearly defined and limited, the terms "mounted", "connected" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0029] As Figures 1 to 5 shown, this embodiment provides a gas stove, which includes a burner head 1, a burner 2 and at least one detection component 3. The burner 2 is detachably arranged on the burner head 1. The detection component 3 includes a first elastic member 31, a push rod 32 and a sensing member 33. The push rod 32 can move relative to the burner head 1. The push rod 32 is connected to the first elastic member 31. When the burner 2 is installed in place, the burner 2 can push the push rod 32 to the detection position. The sensing member 33 is used to sense the detection position of the push rod 32. The first elastic member 31 always has a tendency to drive the push rod 32 to move in the direction of the burner 2 so that the push rod 32 moves away from the detection position.

[0030] By driving the push rod 32 through the first elastic member 31 provided on the burner head 1, when the burner 2 is installed on the burner head 1, the push rod 32 can be pushed to overcome the elastic force of the first elastic member 31 until the push rod 32 is pushed to the detection position where it can be sensed by the sensing member 33 when the burner 2 is installed in place, so as to ensure that the user knows the situation that the burner 2 is installed in place, avoid the occurrence of fire leakage or backfire caused by continued use when the burner 2 is not installed in place, ensure the use safety of the gas stove, and can improve the service life of the burner 2 and the overall gas stove.

[0031] In one embodiment, as Figure 2 and Figure 3 shown, the burner head 1 is provided with a protruding mounting portion 11 in the horizontal direction, a communication port 111 is opened on the mounting portion 11, and the push rod 32 is slidably connected to the communication port 111. It should be noted that the horizontal direction described herein is the horizontal direction, that is, in the normal use state, the burner 2 is installed on the burner head 1 in the vertical direction. By providing the communication port 111 on the mounting portion 11, the communication port 111 circumferentially limits the push rod 32. On the one hand, it can improve the moving guiding property of the push rod 32, and on the other hand, it can improve the moving stability of the push rod 32 when pushed by the first elastic member 31 or pressed by the burner 2.

[0032] Furthermore, the sensing member 33 is a micro switch, the sensing member 33 is connected to the burner head 1, and the sensing member 33 is located on the side of the mounting portion 11 away from the burner 2. The burner 2 can push the push rod 32 to move toward the sensing member 33 against the elastic action of the first elastic member 31 and abut against the sensing member 33 to trigger the sensing member 33. The position where the push rod 32 abuts against the sensing member 33 is the detection position. It can be understood that when the burner 2 is installed on the burner head 1 and pushes the push rod 32 until the push rod 32 abuts against and triggers the sensing member 33, the burner 2 is installed in place. If the burner 2 is installed on the burner head 1 and pushes the push rod 32, and the end of the push rod 32 away from the burner 2 is still spaced from the sensing member 33 and does not trigger the sensing member 33, then the burner 2 is in an un-installed state and the user needs to adjust the position of the burner 2 again. Using the mechanical structure of the micro switch to sense the abutment of the push rod 32 to reflect whether the burner 2 is installed in place, the structure of the detection assembly 3 is simple and the detection effect is good.

[0033] In one embodiment, a stop portion 321 is protruding on the outer periphery of the push rod 32, the first elastic member 31 is sleeved on the outer periphery of the push rod 32, and the first elastic member 31 is located between the stop portion 321 and the mounting portion 11. The first elastic member 31 can be a spring. By sleeving the spring on the outer periphery of the push rod 32 and using the resistance of the stop portion 321, on the one hand, it can limit the spring to prevent the spring from detaching from the push rod 32 and improve the structural stability of the spring installation, and on the other hand, it can also improve the guiding property of the spring during compression to prevent the spring from bending in other directions during the compression process, effectively ensuring the service life of the spring.

[0034] In one embodiment, in combination with Figure 4 and Figure 5 As shown, the gas stove further includes a connecting pipe 4, a switching valve 5, a controller, and a locking member 6. The burner head 1 is communicated with an external gas source through the connecting pipe 4. The switching valve 5 includes a valve shaft 51. The valve shaft 51 is rotatably connected to the connecting pipe 4 to control the on-off of the gas path in the connecting pipe 4. The locking member 6 is disposed on the connecting pipe 4, and the locking member 6 is signal-connected to the sensing member 33 through the controller. The locking member 6 is used to control whether the valve shaft 51 can rotate. Further, only when the sensing member 33 is triggered by the push rod 32, that is, when the burner 2 is installed in place, the sensing member 33 transmits the installed-in-place signal to the controller, and the controller transmits the installed-in-place signal to the locking member 6. The locking member 6 unlocks the valve shaft 51, so that the valve shaft 51 can rotate to perform an ignition operation. In other words, if the sensing member 33 is not triggered by the push rod 32, the burner 2 is not installed in place. At this time, the sensing member 33 does not issue an instruction to perform any action on the locking member 6, and the valve shaft 51 is in a locked state by the locking member 6, and the valve shaft 51 cannot rotate to perform the ignition operation, giving the user an obvious reminder and improving the safety of using the gas stove.

[0035] Specifically, a slot 511 is provided on the outer peripheral side of the valve shaft 51. The locking member 6 includes a driving member 61 and a clamping member 62. When the sensing member 33 detects that the push rod 32 is in the detection position, the sensing member 33 feeds back a signal to the controller, and the controller controls the driving member 61 to drive the clamping member 62 to move away from the valve shaft 51. The clamping member 62 is spaced from the slot 511 to complete the unlocking of the valve shaft 51. At this time, the valve shaft 51 can rotate, that is, the user can turn the valve shaft 51 to open the gas path in the connecting pipe 4 to perform an ignition operation. In other words, when the sensing member 33 detects that the push rod 32 is not in the detection position, that is, the push rod 32 does not abut against the sensing member 33. At this time, the sensing member 33 does not feed back any instruction to the controller, and the controller always keeps the driving member 61 in a state of driving the clamping member 62 to move towards the valve shaft 51, that is, the clamping member 62 is always clamped in the slot 511 to complete the locking of the valve shaft 51, and the valve shaft 51 cannot rotate to inform the user that the burner 2 is not installed in place. The structure of the cooperation between the clamping member 62 and the slot 511 is stably clamped to ensure the connection stability of the locking member 6 to the valve shaft 51.

[0036] In one embodiment, to facilitate the user to rotate the valve shaft 51, the switching valve 5 further includes a knob 52. The knob 52 is disposed at one end of the valve shaft 51 exposed from the connecting pipe 4. The structure of the knob 52 is relatively large, so that the force-bearing area for the user to operate is relatively large, which is convenient for the user to turn. Turning the knob 52 can realize the rotation of the valve shaft 51, improving the operation convenience of the user.

[0037] In one embodiment, the locking member 6 further includes a fixing base 63. A limiting groove 631 is provided on the fixing base 63. The driving member 61 is disposed in the limiting groove 631. The clamping member 62 is at least partially located in the limiting groove 631, and the clamping member 62 is slidably engaged with the groove wall of the limiting groove 631. By restricting the clamping member 62 by the groove wall of the limiting groove 631, the moving directivity and smoothness of the clamping member 62 can be effectively improved, the shaking during the movement of the clamping member 62 can be reduced, and thus the accuracy of the clamping member 62 being clamped in the clamping groove 511 can be improved. In addition, even when the clamping member 62 is in a state of being clamped with the clamping groove 511 under the drive of the driving member 61, the clamping member 62 near one end of the driving member 61 is still located in the limiting groove 631, that is, one end of the clamping member 62 is located in the limiting groove 631 and the other end is clamped in the clamping groove 511. By restricting the clamping member 62 by the bottom of the limiting groove 631, the situation that the user screws the valve shaft 51 to cause the valve shaft 51 to drive the clamping member 62 to rotate and separate the clamping member 62 from the driving member 61 can be avoided, the stability of the clamping member 62 being clamped in the clamping groove 511 can be effectively ensured, and the connection stability between the driving member 61 and the clamping member 62 can be improved.

[0038] Preferably, the driving member 61 includes an electromagnet 611 and a second elastic member 612. The electromagnet 611 is disposed in the limiting groove 631, and the electromagnet 611 is in signal connection with the sensing member 33 through a controller. One end of the second elastic member 612 is connected to the electromagnet 611, and the other end of the second elastic member 612 is connected to the clamping member 62. The clamping member 62 is a magnetic clamping block, and the second elastic member 612 always has a moving tendency to drive the magnetic clamping block to be clamped in the clamping groove 511. When the burner 2 is installed in place, the sensing member 33 is abutted by the push rod 32. At this time, when the electromagnet 611 is energized, it can attract the magnetic clamping block to move away from the valve shaft 51, so that the magnetic clamping block is separated from the clamping groove 511. In other words, when the burner 2 is not installed in place, the sensing member 33 does not generate any instructions, and the magnetic clamping block is clamped in the clamping groove 511 by the driving member 61 of the second elastic member 612 to realize the locking of the valve shaft 51. The second elastic member 612 can adopt a spring, and the spring can always elastically drive the clamping member 62 to be tightly clamped with the clamping groove 511 without borrowing external force, and the connection stability is high.

[0039] In addition, an electromagnet 611 is energized to generate a magnetic force that is the same as or opposite to that of the magnetic engagement block to drive the magnetic engagement block. For example, when the burner 2 is installed in place, the sensing member 33 is abutted by the push rod 32, and the electromagnet 611 is energized with a positive current to form a magnetic electrode opposite to that of the magnetic engagement block, so as to attract the magnetic engagement block to move away from the valve shaft 51, so that the magnetic engagement block is separated from the card slot 511; when the burner 2 is not installed or not installed in place, the electromagnet 611 is energized with a reverse current to form a magnetic electrode the same as that of the magnetic engagement block, so as to repel and push the engagement block to be engaged with the card slot 511. Of course, in other embodiments, the driving member 61 may also be one of linear driving mechanisms such as a cylinder or an oil cylinder.

[0040] In one embodiment, the gas stove includes at least two detection components 3, and all the detection components 3 are arranged in a circumferential and uniform manner on the outer periphery of the burner head 1. For example, the gas stove includes four detection components 3, and the four detection components 3 are arranged in a circumferential and uniform manner on the outer periphery of the burner head 1. When the burner 2 presses the four push rods 32 to respectively abut against the corresponding sensing members 33, the installation in-place detection of the burner 2 is realized. If one or more push rods 32 do not abut against the corresponding sensing members 33, it belongs to the situation where the burner 2 is not installed in place. By providing a plurality of detection components 3, the detection accuracy of the installation in place of the burner 2 is improved. Of course, the number of detection components 3 is not limited to two, three, four or more.

[0041] In one embodiment, as Figure 2 and Figure 3 shown, a guiding portion 12 is provided on one side of the burner head 1 facing the burner 2, and a guiding groove 21 is provided on one side of the burner 2 facing the burner head 1, and the guiding portion 12 is inserted into the guiding groove 21. Through the cooperation of the guiding portion 12 and the guiding groove 21, the guiding property of the installation of the burner 2 can be improved, thereby improving the connection accuracy of the installation of the burner 2 and the burner head 1. Of course, it is not limited to providing the guiding portion 12 on the side of the burner head 1 facing the burner 2 and the guiding groove 21 on the side of the burner 2 facing the burner head 1. The guiding portion 12 may also be provided on the side of the burner 2 facing the burner head 1, and the guiding groove 21 may be provided on the side of the burner head 1 facing the burner 2.

[0042] In the specific content of the above specific embodiments, the technical features can be combined arbitrarily without contradiction. For the sake of concise description, not all possible combinations of the above technical features are described. However, as long as the combinations of these technical features do not contradict each other, they should be considered as within the scope described in this specification.

[0043] The specific content of the above specific embodiments only expresses several embodiments of the present utility model. Its description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
