DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Unless otherwise specified, the above-mentioned directional description can be flexibly set in the process of actual application under the condition that the relative positional relationship shown in the accompanying drawings is satisfied.

[0037] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. It can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] In the embodiments of the present invention, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, article or device including the element.

[0040] In the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present invention should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0041] The present application provides a gas stove, such as Figure 1 As shown, Figure 1 The present invention provides a schematic diagram of a gas stove 100. The gas stove 100 includes a housing 11, which forms an installation cavity 10 with an opening. The opening is connected to the installation cavity 10, so that other relevant components of the gas stove 100 can be installed in the installation cavity 10 of the housing 11. The housing 11 can provide support for the relevant components installed in the installation cavity 10 thereof, as well as a certain degree of protection, to ensure that the gas stove 100 can work normally.

[0042] On this basis, see Figure 1 The gas stove 100 provided in the present application further includes a burner 2. The burner 2 is the core component of the gas stove 100, and the burner 2 includes a burner head 21, which is disposed in the mounting cavity 10 of the housing 11. The burner head 21 can make the fuel and the primary air mixed in a certain manner, and the primary air and fuel mixed in the burner head 21 flow out from the fire outlet hole of the fire cover covered on the burner head 21, and are ignited to form a flame, which heats the bottom of the pot for the user to cook.

[0043] Continue to see Figure 1 The gas stove 100 provided in the present application further includes a panel 12, which is covered on the opening of the housing 11 and is used to cover the mounting cavity 10 of the housing 11. In this way, the panel 12 can prevent debris or food residues dropped during cooking from falling into the mounting cavity 10 of the housing 11, thereby ensuring that other components arranged in the mounting cavity 10 are not damaged or contaminated, and further ensuring that the gas stove 100 can work normally.

[0044] In this case, if Figure 1 As shown, the panel 12 is also provided with an escape opening 120. The burner head 21 is arranged opposite to the escape opening 120 provided on the panel 12, so that the burner head 21 can be located within the opening range of the escape opening 120 of the panel 12. In this way, when the burner 2 burns fuel to generate flames, the panel 12 will not block the flames generated by the burner 2 burning fuel, ensuring that the burner 2 can work normally, so that the flames can heat the bottom of the pot, so that the user can cook.

[0045] As can be seen from the above, a gas stove 100 provided in an embodiment of the present application may include a shell 11, a panel 12, and a burner 2, which is the core component of the gas stove 100. The burner 2 may be installed in the installation cavity 10 of the shell 11, and then the installation cavity 10 of the shell 11 is covered by the panel 12 to protect other components arranged in the installation cavity 10, to ensure that the burner 2 and other components will not be damaged, thereby ensuring that the gas stove 100 can work normally.

[0046] like Figure 2 As shown, the burner provided in the present application further includes an ejector pipe 22. The ejector pipe 22 has a gas inlet 221 and a gas outlet 222 which are arranged opposite to each other. Figure 3 As shown, Figure 3 A schematic diagram of an ejector tube provided in an embodiment of the present application, wherein the burner head 21 forms a gas mixing chamber with an opening, and is provided with a gas mixing inlet connected to the gas mixing chamber. The gas outlet 222 of the ejector tube 22 is connected to the gas mixing inlet of the burner head, and the gas inlet 221 of the ejector tube 22 enables the fuel to enter the ejector tube 22 and then flow into the gas mixing chamber of the burner head 21.

[0047] In addition, the burner provided in the embodiment of the present application further includes a fire cover. The fire cover is arranged on the opening of the gas mixing chamber. A fire outlet hole is provided on the fire cover, and one end of the fire outlet hole is connected to the gas mixing chamber. In this way, the primary mixed air in the gas mixing chamber can flow out through the outlet hole.

[0048] In addition, in order to ignite the primary mixed air flowing out of the fire outlet, the gas stove provided in the embodiment of the present application further includes an ignition needle 24, which is installed on the burner 21. The gas passes through the nozzle 23 and the air through the air intake contraction tube to enter the ejector tube for the first mixing, and is mixed with the outside air for the second time when reaching the gas mixing chamber of the burner 21 to form a gas-air mixture, and then the voltage is increased by the piezoelectric ceramic or pulse generator in the ignition device. After the voltage is increased to a certain value (generally 10-20 kV), the air is broken down. When the air between the ignition needle 24 and the burner 21 is broken down, an arc or electric spark is formed. The electric energy of the arc or electric spark is converted into heat energy when the discharge, so that the temperature of the local space rises sharply to reach the ignition point of the gas to ignite the gas (the ignition point of natural gas is 650 degrees, and the ignition point of liquefied petroleum gas is 490 degrees).

[0049] like Figure 4As shown, in order to install the ignition needle 24, a mounting hole 211 is provided on the burner head 21. Based on this, the ignition needle 24 is inserted into the mounting hole 211. In this way, the ignition needle 24 can be installed on the burner head 21. The mounting hole 211 circumferentially fixes the ignition needle 24 on the plane where it is located. At the same time, in order to further fix the ignition needle 24, the gas stove 100 may also include a fixing device 25, which can be used to fix the ignition needle 24 on the plane where the fixing device 25 is located, so that the ignition needle 24 can be firmly fixed on the burner head 21.

[0050] like Figure 5 As shown, the peripheral wall of the ignition needle 24 has a first limiting portion 241 and a second limiting portion 242. The first limiting portion 241 can be located on one side of the mounting hole 211 and abut against the upper end surface of the burner head 21. The second limiting portion 242 can be located on the other side of the mounting hole 211 opposite to the first limiting portion 241.

[0051] At the same time, if Figure 6 As shown, the fixing device 25 is located on one side of the mounting hole 211 close to the second limiting portion 242, and is installed between the burner head 21 and the second limiting portion 242. One end of the fixing device 25 has an avoidance gap 251. The portion of the ignition needle 24 between the first limiting portion 241 and the second limiting portion 242 is located in the avoidance gap 251 ( Figure 8 ), the two sides of the fixing device 25 are respectively against the second limiting portion 242 and the lower end surface of the furnace head 21.

[0052] Thus, in the actual installation process, the ignition needle 24 can be firstly inserted into the installation hole 211, and then, Figure 7 , the fixing device 25 can extend between the second limiting portion 242 and the burner head 21 along the direction of the avoidance notch 251. This fixing device 25 that only needs to be inserted is easy to install. Since the first limiting portion 241 is located on one side of the mounting hole 211 and abuts against the upper end surface of the burner head 21, the ignition needle 24 can be restricted from moving toward the other side close to the mounting hole 211.

[0053] At the same time, the two sides of the fixing device 25 respectively abut against the second limiting portion 242 and the lower end surface of the burner head 21. In this way, the fixing device can limit the movement of the ignition needle 24 toward the mounting hole 211 close to the first limiting portion 241, so that the ignition needle 24 does not move in the vertical direction and can be firmly fixed on the burner head 21.

[0054] In some embodiments, the first avoidance notch 2511 and the second avoidance notch 2522 may be provided with elastic rubber material with a large friction coefficient at the contour edge. In this way, the elastic deformation of the rubber material can better fit the peripheral wall of the ignition needle 24, and at the same time, a large friction force will be provided to limit the circumferential rotation of the ignition needle 24 and the fixing device 25 when the ignition needle 24 and the fixing device 25 are relatively displaced.

[0055] It can be understood that, in order to facilitate the ignition needle 24 to pass through the mounting hole 211, the radial dimension of the second limiting portion 242 can be smaller than the aperture dimension of the mounting hole 211, that is, the second limiting portion 242 can pass through the mounting hole 211. In this way, during installation, one end of the ignition needle where the second limiting portion 242 is located can pass through the mounting hole 211 and be located at the other end of the mounting hole.

[0056] Of course, the radial dimension of the second limiting portion 242 can be larger than the aperture dimension of the mounting hole 211. In this case, the second limiting portion 242 can have a certain elastic deformation capability. In this way, during the installation process, the second limiting portion 242 of the ignition needle can be elastically deformed and pass through the mounting hole 211 to be located at the other end of the mounting hole. At the same time, when the fixing device 25 applies an axial force to the second limiting portion 242, the second limiting portion 242 will not be deformed so that the second limiting portion 242 will not pass through the avoidance notch 251 set by the fixing device 25.

[0057] In some embodiments, Figure 8 The fixing device 25 may include a first fixing portion 252 and a second fixing portion 253. One end of the first fixing portion 252 has a first avoidance gap 2511. One end of the second fixing portion 253 has a second avoidance gap 2512 connected to one end of the first fixing portion 252. The second avoidance gap 2512 and the first avoidance gap 2511 are connected to form the avoidance gap 251. There is a gap between the other end of the second fixing portion 253 and the other end of the first fixing portion 252.

[0058] In this way, the first avoidance gap 2511 of the first fixing part 252 and the second avoidance gap 2512 of the second fixing part 253 are connected to form the avoidance gap 251. During the installation of the fixing device 25, the ignition needle 24 can be located in the first avoidance gap 2511 and the second avoidance gap 2512, so that a part of the first fixing part 252 and a part of the second fixing part 253 can be located between the burner 21 and the second limiting part 242, limiting the displacement of the ignition needle 24.

[0059] Based on this, when the fixing device 25 is installed, the contour of the avoidance notch 251, that is, a portion of the contour of the avoidance notch 2511 and the avoidance notch 2522, can fit the peripheral wall of the ignition needle 24, which can achieve a better circumferential fixing effect. At the same time, the opening angle of the avoidance notch 251 can be increased to provide a better guiding effect during the installation process.

[0060] Since there is a gap between the other end of the second fixing portion 253 and the other end of the first fixing portion 252. Figure 8 As shown, the other end of the first fixing portion 252 and the other end of the second fixing portion 253 may form an opening having a certain size.

[0061] In this way, when the first fixing part 252 abuts against the burner head 21 and the second fixing part 253 abuts against the second limiting part 242, the size of the opening formed by the first fixing part 252 and the second fixing part 253 can be changed by applying pressure to the first fixing part 252 and the second fixing part 253. Due to the rigidity of the material of the fixing device 25, the fixing device 25 will generate a reaction force on the burner head 21 and the second limiting part 242, and the second limiting part 242 will be displaced in the direction away from the fixing device 25 under the force.

[0062] At the same time, the ignition needle 24 is driven to move, but because the first limit portion 241 of the ignition needle is subjected to the opposite force of the burner head 21, the fixing device 25 has a reaction force in the same direction on the burner head 21, so that the ignition needle 24 can be better fixed and will not be displaced.

[0063] It is understandable that the avoidance gap can also be opened at the other end where the first fixing portion 252 and the second fixing portion 253 are connected, so that the reaction force generated by the rigidity of the fixing device acting on the burner head 21 and the second limiting portion 242 can also play a fixing role. This is not shown here.

[0064] In some embodiments, the first fixing portion 252 and the second fixing portion 253 can be integrally made of stainless steel. Similarly, the first fixing portion 252 and the second fixing portion 253 can also be integrally thermoformed by acrylic. Exemplarily, the first fixing portion 252 and the second fixing portion 253 can be a sheet structure, and the first fixing portion 252 and the second fixing portion 253 can be formed by bending stainless steel material. Of course, in other embodiments, the first fixing portion 252 and the second fixing portion 253 can also be made separately and then connected to each other, which can be selected according to actual conditions, and no further explanation is given here. In some embodiments, at least one of the other end of the first fixing portion 252 and the other end of the second fixing portion 253 is bent to form a holding portion 254. Thus, when the operator holds it, it can be used to hold the holding portion, and the arc structure increases the contact area and reduces the pressure when applying force, thereby protecting the operator's safety and facilitating installation.

[0065] Of course, in other embodiments, the other end of the first fixing portion 252 and the other end of the second fixing portion 253 can also be bent to form a holding portion 254. At this time, when installing the fixing device 25, the staff can directly hold the other end of the first fixing portion 252 and the other end of the second fixing portion 253 for installation.

[0066] In some embodiments, Figure 8 As shown in FIG. 1 , the handle 254 may be an arc-shaped structure. Thus, when the user holds the handle 254, the handle portion is an arc-shaped structure, which makes it easier for the user to hold the handle 254. Of course, in other embodiments, such as Fig.14 The holding portion 254 may also be a flat sheet structure.

[0067] Based on the above solution, when at least one of the other end of the first fixing portion 252 and the other end of the second fixing portion 253 is bent to form a holding portion 254, the bending direction of the holding portion may be different. In some embodiments, the holding portion 254 may be formed into a protrusion in a direction away from the end where the first fixing portion 252 and the second fixing portion 253 are connected to each other. Figure 8 As shown, when installing the fixing device, the user can hold the handle more conveniently, which makes the operation more convenient.

[0068] The number of the holding portions can be set according to actual conditions. In some embodiments, the other end of the first fixing portion 252 can be formed with a holding portion 254. Figure 8 As shown, when only the other end of the first fixing part is formed with a holding portion, and the arc-shaped structure of the holding portion forms a protrusion in the direction away from the end where the first fixing part and the second fixing part are connected to each other, the user can conveniently hold the fixing device 25 only by the holding portion 254 formed at the other end of the first fixing part 252.

[0069] based on Figure 8 In the embodiment shown, a recess is formed on one side of the gripping portion 254 near the end where the first fixing portion 252 and the second fixing portion 253 are connected. The other end of the second fixing portion 253 can be arranged opposite to the recess. In this way, when the user holds the fixing device 25, since the other end of the second fixing portion 253 is arranged opposite to the recess, it is not easy for the user to touch the other end of the second fixing portion 253, thereby preventing the other end of the second fixing portion 253 from causing damage to the user.

[0070] Of course, in other embodiments, such as Fig.14, the other end of the first fixing part 252 and the other end of the second fixing part 253 may both be formed with a gripping part 254. At this time, since the other end of the first fixing part 252 and the other end of the second fixing part 253 are respectively formed with gripping parts 254, the user can hold the two gripping parts at the same time for operation, which is more convenient.

[0071] In some embodiments, Fig. 9 The surface of the furnace head 21 against which the fixing device 25 abuts has a limiting groove 212 ( Fig.10 ).like Figure 8 The fixing device further includes a first clamping portion 2521. One end of the first clamping portion 2521 is connected to a surface of the first fixing portion 252 away from the second fixing portion 253, and the other end extends toward a surface of the first fixing portion 252 away from the second fixing portion 253.

[0072] In this way, during the installation process, the first clamping portion 2521 can be elastically deformed against the surface of one side of the furnace head 21. When the first clamping portion 2521 is arranged opposite to the limiting groove 212, the first clamping portion 2521 can restore the elastic deformation and be clamped in the limiting groove 212. Figure 6 As shown, the first clamping portion 2521 can limit the fixing device 25 from being displaced in the direction away from the installation, so that the fixing device 25 can not move in the direction away from the installation, thereby preventing the ignition needle 24 from escaping from the avoidance gap 251.

[0073] It is understandable that the specific form of the first clamping portion 2521 can be set according to actual conditions. For example, the first clamping portion 2521 can be a sheet structure, one end of which is connected to the first fixing portion 252. The first clamping portion 2521 is inclined, and the other end is away from the first fixing portion 252.

[0074] In some embodiments, a first accommodating hole 2522 is defined on a surface of the first fixing portion 252 away from the second fixing portion 253 ; one end of the first clamping portion 2521 is located around the first accommodating hole 2522 , and the first clamping portion 2521 is disposed opposite to the first accommodating hole 2522 .

[0075] In this way, during the installation of the fixing device 25 , the first clamping portion 2521 can be compressed into the first accommodating hole 2522 , so that the fixing device 25 can be installed even when the interval between some furnace heads 21 and the second limiting portion 242 is small.

[0076] Exemplarily, the first receiving hole 2522 may be a through hole. Of course, in other embodiments, the first receiving hole 2522 may also be a blind hole, in which case the thickness of the first clamping portion 2521 should be smaller than the depth of the first receiving hole 2522 .

[0077] Of course, in some other embodiments, the surface of the first fixing portion 252 away from the second fixing portion 253 may not be provided with the first receiving hole 2522 .

[0078] In some embodiments, Fig. 9 As shown, the second fixing portion 253 is located on the first fixing portion 252 ( Figure 8 ) on the first clamping portion 2521 ( Figure 8 ) and the first receiving hole 2522 ( Figure 8 ) A second clamping portion 2531 and a second receiving hole 2532 may be provided at a relative position of the second fixing portion 253. The second clamping portion is deformed by pressure during installation so that the second avoidance notch 2512 and the second clamping portion are both against the ignition needle 24, thereby providing better support.

[0079] In some embodiments, Figure 7 , Fig.10 , Fig.11 As shown, a first abutting portion 2131 and a second abutting portion 2132 are formed on the surface of the furnace head 21 close to the fixing device 25; the first abutting portion 2131 and the second abutting portion 2132 are arranged at intervals along the first direction; the fixing device 25 is located between the first abutting portion 2131 and the second abutting portion 2132, and along the second direction, one end of the fixing device 25 has an avoidance notch 251. The first direction and the second direction are perpendicular to each other and are parallel to the plane where the opening of the mounting hole 211 is located.

[0080] In this way, when the fixing device 25 is installed, the first abutment portion 2131 and the second abutment portion 2132 can limit the circumferential rotation of the fixing device 25 around the ignition needle 24, making the fixing of the fixing device more stable. Fig.10 , Fig.11 , Fig.12 As shown, the distance W1 between the first abutting portion 2131 and the second abutting portion 2132 may be consistent with the width W1 of the fixing device 25 in the first direction, thereby achieving a better limiting effect.

[0081] Specifically, Fig.13 The length of the first fixing portion 252 of the fixing device 25 is set to 18 cm, and the width is set to 10 cm. Figure 8 ) The opening width is 4.9 cm and the length is 7.2 cm. The bending length of the holding portion 254 is 3 cm, the fillet radius is 5 cm, and the length of the second fixing portion 253 is 14.9 cm.
