[0030] As Figure 1 shown, Figure 1 schematically illustrates a composition principle of the disclosed gas stove 100. The gas stove 100 includes a bottom shell ( Figure 1 not shown in the figure), a receiving end 110, an ignition pin 120, and an ignition mechanism 130. The ignition mechanism 130 is disposed inside the bottom shell and includes an igniter 131 and an ignition wire 132. Among them, the ignition wire 132 connects the igniter 131 and the ignition pin 120, and the ignition pin 120 is grounded through the receiving end to be able to discharge to the receiving end 110. The receiving end 110 is configured to be insulated from the bottom shell 150. The electronic transfer line is simple, and electrons do not pass through the bottom shell 150 when transmitted from the igniter 131, thereby avoiding electron loss and then ensuring the ignition success rate.

[0031] Optionally, the gas stove 100 further includes a ground wire 133. The ground wire 133 connects the igniter 131 and the receiving end 110 to form a loop for the ignition pin 120 to discharge to the receiving end 110. When the ignition pin 120 discharges to the receiving end 110, it can ignite the gas at the burner 140.

[0032] The ground wire 133 is connected to the receiving end 110, and at the same time, the receiving end 110 is configured to be insulated from the bottom shell 150. Electrons do not pass through the bottom shell 150 when transmitted from the igniter 131, thereby avoiding electron loss and then ensuring the ignition success rate.

[0033] The following describes different embodiments of the gas stove 100 based on the above composition principle with reference to the drawings.

[0034] As shown Figure 2 in Figure 2 the figure, the structure of a gas cooker 100 according to an embodiment of the present disclosure is illustrated. The gas cooker 100 includes a bottom case 150, a receiving end 110, and an ignition pin 120. An ignition mechanism 130 is provided inside the bottom case 150. The ignition mechanism 130 includes an igniter 131, an ignition wire 132, and a ground wire 133. Among them, the ignition wire 132 connects the igniter 131 and the ignition pin 120, and the ground wire 133 connects the igniter 131 and the receiving end 110 to form a loop for the ignition pin 120 to discharge to the receiving end 110. Among them, the receiving end 110 is insulated and isolated from the bottom case 150. In this embodiment, the gas cooker 100 further includes a burner 140, and the receiving end 110 is the burner 140.

[0035] Exemplarily, the burner 140 includes a burner base and a burner head. The burner base is provided inside the bottom case 150. The receiving end 110 is specifically the burner base of the burner 140. When the gas cooker 100 includes a panel, the burner head is located above the panel of the gas cooker 100.

[0036] The burner 140 is insulated and isolated from the bottom case 150, and the specific method is not limited. Optionally, the burner base is installed on the bottom case 150 through an insulating connection structure. The insulating connection structure includes an insulating bracket and a fastener. The burner base is disposed on the insulating bracket, and the fastener fixes the insulating bracket to the bottom case 150. Optionally, the bottom case 150 is an insulating member.

[0037] In some embodiments, a gas conduction structure 160 is further provided inside the bottom case 150. The gas conduction structure 160 includes an injector 161, a valve body 162, and an intake pipe 163 that are connected in sequence. The injector 161 is communicated with the gas inlet of the burner 140, and the ground wire 133 is connected to the injector 161, the valve body 162, or the intake pipe 163.

[0038] On the premise that the receiving end 110 is insulated and isolated from the bottom case 150, one end of the ground wire 133 is connected to the igniter 131, and the other end of the ground wire 133 can be selectively connected to the injector 161, the valve body 162, or the intake pipe 163, thereby providing more design choices. Optionally, the bottom case 150 is directly configured as an insulating member, so that the connection position of the other end of the ground wire 133 can be arbitrarily selected.

[0039] In Figure 2In the illustrated embodiment, the ground wire 133 is connected to the ejector 161. The ejector 161 is electrically connected to the burner 140, and at the same time, the ejector 161 is insulated from the bottom case 150. Since the ejector 161 is electrically connected to the burner 140, after the ground wire 133 is connected to the ejector 161, the ejector 161 can transfer electrons to the burner 140 as the receiving end 110. Moreover, by insulating the ejector 161 from the bottom case 150 and insulating the ejector 161 from the valve body 162, electrons can only be transferred to the burner 140 after reaching the ejector 161, and the electrons do not pass through the bottom case 150, so there is no electron loss, thus ensuring the ignition success rate. In addition, the ground wire 133 is connected to the gas conduction structure 160 of the gas cooker 100 itself, and the circuit structure is simple.

[0040] The implementation method of insulating the ejector 161 from the bottom case 150 is not limited. Optionally, an insulating support member is provided between the ejector 161 and the bottom case 150. For example, the insulating support member is an insulating bracket or an insulating gasket. Or, an insulating layer is provided on the surface of the ejector 161 or the bottom case 150. The insulating layer is, for example, insulating paint. Or, the bottom case 150 is an insulating member.

[0041] Preferably, when the ground wire 133 is connected to the ejector 161, the ejector 161 is insulated from the bottom case 150 and the ejector 161 is insulated from the valve body 162, thereby eliminating the possibility of electrons reaching the ejector 161 and being transferred to the valve body 162, avoiding electron loss, and ensuring the ignition success rate. The implementation method of insulating the ejector 161 from the valve body 162 is not limited. Optionally, at least one of the ejector 161 and the valve body 162 is provided with an insulating coating, and the insulating coating insulates them from each other when they are connected. Optionally, an insulating gasket is provided between the ejector 161 and the valve body 162, and the insulating gasket insulates them from each other when they are connected.

[0042] The method of connecting the ground wire 133 to the ejector 161 is not limited. Optionally, the ground wire 133 is directly connected to the ejector 161 itself. Optionally, referring to Figure 2 , the ejector 161 is supported by an insulating bracket 1611 and fixed to the bottom case 150 by a fastener 1612. The ground wire 133 is connected to the fastener 1612 and is pressed by the fastener 1612 against the insulating bracket 1611. The part of the fastener 1612 in contact with the bottom case 150 is insulated from the bottom case 150. The ground wire 133 is connected to the ejector 161 through the fastener 17, thereby realizing both the electrical connection between the ground wire 133 and the ejector 161 and ensuring the insulation between the ejector 161 and the bottom case 150.

[0043] Generally, the valve body 162 is also configured to be insulated from the bottom case 150. The implementation method is not limited and can be the same as various implementation methods of insulating the ejector 161 from the bottom case 150.

[0044] As Figure 2 shown, two burners 140, two sets of gas conduction structures 160 and two sets of ignition mechanisms 130 are provided in the bottom shell 150. The two sets of gas conduction structures 160 share a common intake pipe 163, and the two sets of ignition mechanisms 130 share a common igniter 131. In this embodiment, each of the two sets of ignition mechanisms 130 is provided with a ground wire 133. The two ground wires 133 are respectively connected to the two ejectors 161 to the igniter 131 in a one-to-one correspondence.

[0045] Figure 3 Figure 100 shows a gas cooker 100 according to another embodiment of the present disclosure, which adopts an overall structure similar to that of the Figure 2 gas cooker 100 shown in Figure 100. The difference is that the ground wire 133 is connected to the valve body 162, and the valve body 162, the ejector 161, and the burner 140 are electrically connected in sequence. Moreover, both the ejector 161 and the valve body 162 are insulated from the bottom shell 150. After the electrons reach the valve body 162, they are transmitted to the burner 140 through the ejector 161. Since the electrons do not pass through the bottom shell 150, no electron loss will occur, thus ensuring the ignition success rate.

[0046] Preferably, when the ground wire 133 is connected to the valve body 162, the valve body 162 is also insulated from the intake pipe 163, thereby eliminating the possibility of electrons reaching the intake pipe 163 after reaching the valve body 162, avoiding electron loss, and ensuring the ignition success rate.

[0047] Generally, when the ground wire 133 is connected to the valve body 162, the intake pipe 163 is also configured to be insulated from the bottom shell 150. The implementation method of insulating the intake pipe 163 from the bottom shell 150 is not limited. For example, it can be similar to the implementation method of insulating the ejector 161 or the valve body 162 from the bottom shell 150, which will not be elaborated here.

[0048] The implementation method of insulating the valve body 162 from the intake pipe 163 is not limited. Optionally, at least one of the valve body 162 and the intake pipe 163 is provided with an insulating coating, which insulates them from each other when they are connected. Alternatively, an insulating gasket is provided between the valve body 162 and the intake pipe 163, which insulates them from each other when they are connected.

[0049] Figure 4 Figure 100 shows a gas cooker 100 according to yet another embodiment of the present disclosure, which adopts an overall structure similar to that of the Figure 2 gas cooker 100 shown in Figure 100. The difference is that the ground wire 133 is connected to the intake pipe 163, and the intake pipe 163, the valve body 162, the ejector 161, and the burner 140 are electrically connected in sequence. Moreover, the ejector 161, the valve body 162, and the intake pipe 163 are all insulated from the bottom shell 150.

[0050] After the electrons are transferred to the intake pipe 163, they then pass through the valve body 162 and the injector 161 in sequence and are transferred to the burner 140. Since the electrons do not pass through the bottom case 150, there will be no electron loss, thus ensuring the ignition success rate.

[0051] Furthermore, in this embodiment, the two ignition mechanisms 130 also share a ground wire 133. The ground wire 133 is connected to the intake pipe 163 shared by the two gas conduction structures 160. After the electrons reach the intake pipe 163, they then flow to the corresponding injector 161. This way, it is not necessary to set multiple ground wires 133, reasonably utilizing the existing structure of the gas stove 100 and simplifying the circuit design.

[0052] In the present disclosure, it is not limited to setting two gas conduction structures 160 and two ignition mechanisms 130. For example, three groups can also be set. At this time, the three ignition mechanisms 130 can share a ground wire 133.

[0053] When the receiving end 110 is the burner 140, in some alternative embodiments, the ground wire 133 is connected to the burner 140, and the burner 140 and the injector 161 are insulated from each other. Here, the ground wire 133 being connected to the burner 140 means that the ground wire 133 is not electrically connected to the burner 140 through the gas conduction structure 160, but is directly connected to the burner 140. There can be direct contact between the ground wire 133 and the burner 140 or other intermediate conductive media provided.

[0054] The burner 140 and the injector 161 are insulated from each other and cannot be electrically conducted. For example, the surface of the injector 161 has a heat-resistant insulating coating, and the injector 161 and the burner 140 cannot be electrically conducted. For example, an insulating gasket is provided between the injector 161 and the burner 14, and the insulating gasket makes the injector 161 and the burner 140 unable to be electrically conducted.

[0055] The electrons are transferred to the burner 140 through the ground wire 133, and the electrons will not be guided by the injector 161 to the bottom case 150, thus avoiding electron loss and ensuring the ignition success rate. Specifically, when the burner 140 and the injector 161 are insulated from each other, after the electrons reach the burner 140 through the ground wire 133, they cannot be transferred to the injector 161, thus avoiding electron loss. When the injector 161 and the bottom case 150 are insulated from each other, after the electrons reach the burner 140, even if some electrons flow to the injector 161, they can only flow back to the burner 140 and will not be transferred to the bottom case 150, thus avoiding electron loss.

[0056] In some embodiments, the ground wire 133 includes a first wire, a second wire, and a third wire with different lengths from each other. The first wire, the second wire, and the third wire are respectively used to connect to the ejector 161, the valve body 162, and the intake pipe 163. In this way, according to the different connection objects of the ground wire 133, wires with corresponding lengths are selected, so as to avoid using long wires in short-distance connection scenarios, thereby ensuring a shorter electronic transmission path.

[0057] There are positions for connecting the ground wire 133 on the igniter 131, the ejector 161, the valve body 162, the intake pipe 163, and the burner 14 respectively, and this position can be called the wire connection point. Optionally, the length of the first wire is configured to be equal to the shortest distance between the wire connection point of the igniter 131 and the wire connection point of the ejector 161. The length of the second wire is configured to be equal to the shortest distance between the wire connection point of the igniter 131 and the wire connection point of the valve body 162. The length of the third wire is configured to be equal to the shortest distance between the wire connection point of the igniter 131 and the wire connection point of the intake pipe 163. The ground wire 133 further includes a fourth wire, and the length of the fourth wire is configured to be equal to the shortest distance between the wire connection point of the igniter 131 and the wire connection point of the burner 140.

[0058] It should be noted that the above-mentioned shortest distance may be the straight-line distance between two points; it may also be the shortest path on the premise of bypassing the obstacles that must be bypassed.

[0059] As Figure 5 shown, Figure 5 schematically shows another structural principle of the gas stove 100 of the present disclosure. At this time, the overall architecture of the actually formed gas stove 100 can be similar to any one of the gas stoves 100 described in Figures 2 to 4 The difference is that the receiving end 110 is a metal part insulated from the bottom shell 150, and the metal part is close to the ignition needle 120 so that the ignition needle 120 can discharge to the metal part. When the receiving end 110 is a metal part insulated from the bottom shell 150, after the gas stove 100 is installed, the metal part passes through the panel and the water receiving tray of the gas stove, and the upper end of the metal part is located near the burner 140.

[0060] Optionally, the metal part is a thermocouple 170 installed on the burner 140, and the thermocouple 170 is used for flameout protection of the burner 140. At this time, the ground wire 133 can be connected to the thermocouple 170, the burner 140, or the gas conduction structure 160. The burner 140 and the bottom shell 150 are insulated from each other so that the thermocouple 170 is insulated from the bottom shell 150.

[0061] Optionally, the metal part is installed on the bottom shell 150 and is insulated from the bottom shell 150. For example, the metal part is installed on the bottom shell 150 through an insulating bracket.

[0062] In some embodiments, the bottom case 150 is an insulating member. At this time, the ground wire 133 can be arbitrarily connected to any one of the thermocouple 170, the burner 140, or the gas conduction structure 160, which can avoid the transfer of electrons to the bottom case 150, avoid electron loss, and ensure the ignition success rate.

[0063] In this application, unless otherwise clearly defined and limited, if terms such as "installed", "connected", "connected to", "fixed" appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0064] In this application, unless otherwise clearly defined and limited, if a first feature is described as "on" or "under" a second feature or the like, its meaning can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over", and "on" the second feature can be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath", and "under" the second feature can be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0065] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right", and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0066] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0067] The above embodiments only represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
