[0027] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.
[0028] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0029] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.
[0030] The embodiment of the utility model provides a piezoelectric ignition structure, such as Figure 1 and Figure 2As shown, it includes a connecting member 100, a first handle 210, a second handle 220 and a piezoelectric igniter 300. One end of the first handle 210 and one end of the second handle 220 are both fixed to the connecting member 100, and the other end of the first handle 210 and the other end of the second handle 220 are both free ends 201. Since the free end 201 is not directly fixed, it can be pressed by the user. The piezoelectric igniter 300 is fixed on the second handle 220, and the trigger end 310 of the piezoelectric igniter 300 faces the first handle 210. The trigger end 310 of the piezoelectric igniter 300 is a component on the piezoelectric igniter 300 that can trigger the piezoelectric igniter 300 to discharge and ignite, which can be a button type or other forms. Since the trigger end 310 faces the first handle 210, it provides a condition for the first handle 210 to press against the trigger end 310 when it approaches the trigger end 310. At least one of the first handle 210 and the second handle 220 is elastically deformable. Since it is elastically deformable, when a user operates the elastically deformable handle, it can bend, so that the first handle 210 and the second handle 220 can be brought closer to each other.
[0031] When in use, the user can press the free end 201 of the first handle 210 and the free end 201 of the second handle 220 by hand, and the free end 201 of the first handle 210 and the free end 201 of the second handle 220 will approach each other, which will correspondingly make the trigger end 310 of the piezoelectric igniter 300 and the first handle 210 approach each other, and the first handle 210 can press the trigger end 310 of the piezoelectric igniter 300, thereby causing the piezoelectric igniter 300 to discharge and ignite, so that the user's operation is simpler and the user's experience can be improved. At the same time, the first handle 210 and the second handle 220 form a lever-like structure, and when the user operates from the free end 201, a greater torque can be generated, so the operation is relatively labor-saving.
[0032] In some embodiments, the first handle 210 includes a pressure plate 211 extending toward the trigger end 310 of the piezoelectric igniter 300 . When the free end 201 of the first handle 210 and the free end 201 of the second handle 220 approach each other, the pressure plate 211 can press the trigger end 310 of the piezoelectric igniter 300 .
[0033] Compared with pressing the trigger end 310 of the piezoelectric igniter 300 by the first handle 210, the force of the pressing plate 211 when pressing the trigger end 310 of the piezoelectric igniter 300 is relatively concentrated, and it is easier to press the trigger end 310. At the same time, since the pressing plate 211 extends toward the trigger end 310 of the piezoelectric igniter 300, the initial distance between the pressing plate 211 and the trigger end 310 of the piezoelectric igniter 300 can be reduced, and the first handle 210 or the second handle 220 can press the trigger end 310 of the piezoelectric igniter 300 with a small deformation, which makes the user's operation more labor-saving.
[0034] In some embodiments, both the first handle 210 and the second handle 220 can be elastically deformed, and the first handle 210 and the second handle 220 can be bent toward each other, which can reduce the deformation of any one of the first handle 210 and the second handle 220, thereby making it easier to press against the trigger end 310 of the piezoelectric igniter 300, making it more convenient and labor-saving for users to operate.
[0035] In some embodiments, the piezoelectric igniter 300 is located in the middle of the second handle 220 in the length direction thereof. Compared with fixing the piezoelectric igniter 300 at one end close to the free end 201, when the piezoelectric igniter 300 is located in the middle position, the torque generated when the user operates the free end 201 is larger and more labor-saving. At the same time, since the deformation of the first handle 210 and / or the second handle 220 starts from the free end 201, the deformation of the first handle 210 and the second handle 220 at one end fixed to the connecting member 100 is small. Compared with fixing the piezoelectric igniter 300 at one end close to the connecting member 100, when the piezoelectric igniter 300 is located in the middle position, it is easier to press against the trigger end 310 of the piezoelectric igniter 300. Therefore, when the piezoelectric igniter 300 is located in the center, it can not only enable the user to have a larger torque when operating, but also enable the deformation of the first handle 210 and / or the second handle 220 to be sufficient to press the trigger end 310 of the piezoelectric igniter 300, which is a more ideal position.
[0036] In some embodiments, the first handle 210 and the second handle 220 may be strip-shaped, parallel to each other and separated by a preset distance (the preset distance is reasonably determined by technical personnel in this field according to actual conditions), which facilitates the configuration of the piezoelectric igniter 300, thereby making it easier to trigger the piezoelectric igniter 300.
[0037] In some embodiments, the free end 201 of the first handle 210 and the free end 201 of the second handle 220 are both bent upward. On the one hand, this can increase the contact area between the user's fingers and the free end 201, making it more comfortable to press the free end 201. On the other hand, the inherent structure on the gas stove body can be circumvented by bending, so that the free end 201 can be easily extended out of the gas stove body.
[0038] In some embodiments, one end of the first handle 210 close to the connector 100 and one end of the second handle 220 close to the connector 100 are both connected to a fixing plate 202, and the fixing plate 202 of the first handle 210 and the fixing plate 202 of the second handle 220 are both fixedly connected to the connector 100. Compared with the end of the handle, the fixing plate 202 has a relatively larger area, which increases more installation space and is easier to fix to the connector 100.
[0039] Furthermore, the fixing plate 202 can be fastened to the connector 100 by screws, and the fixing by screws is easy to install and convenient to disassemble. Of course, the fixing plate 202 can also be fixed to the connector 100 by welding, gluing, snap-fit connection and other methods.
[0040] In some embodiments, two limiting plates 110 are disposed on the connector 100, and the two fixing plates 202 are located between the two limiting plates 110, and the two limiting plates 110 respectively abut against the outer sides of the two fixing plates 202. The limiting plates 110 play a positioning role in the installation of the fixing plates 202, so that the installation position of the fixing plates 202 can be intuitively understood, and the fixing plates 202 can be conveniently fixed to the connector 100.
[0041] In the above embodiment, the free end 201, the first handle 210, the first pressure plate 211 and the fixed plate 202 can be connected as a whole, and the free end 201, the second handle 210 and the fixed plate 202 can also be connected as a whole to facilitate overall manufacturing and strengthen the connection strength between each other.
[0042] In some embodiments, the first handle 210 and / or the second handle 220 may be made of an elastically deformable material, such as plastic, etc., so as to realize elastic deformation of the first handle 210 and / or the second handle 220. Of course, the first handle 210 and / or the second handle 220 may also be made of conventional materials, such as metal materials, etc., and the first handle 210 and / or the second handle 220 may be made thinner to facilitate elastic deformation.
[0043] In some embodiments, Figure 1 and Figure 2 As shown, a clamping hole is provided on the second handle 220, and the piezoelectric igniter 300 is clamped and fixed in the clamping hole. Of course, the piezoelectric igniter 300 can also be fixed on the second handle 220 by welding, gluing, snap connection and other methods.
[0044] The embodiment of the utility model also provides a gas stove, such as Figure 3 As shown, the gas stove body 400 and the piezoelectric ignition structure of any of the above embodiments are included. The specific description of the piezoelectric ignition structure can refer to the above embodiments and will not be repeated here. The connecting piece is connected to the gas stove body 400, so the user can trigger the piezoelectric igniter to discharge and ignite by operating the free end of the first handle and the free end of the second handle, so that the gas stove body 400 burns.
[0045] In some embodiments, Figure 4As shown, the connector 100 and the piezoelectric igniter 300 are both located inside the gas stove body 400, which can hide the piezoelectric igniter 300 and protect the piezoelectric igniter 300. At the same time, the free end 201 of the first handle 210 and the free end 201 of the second handle 220 are both extended to the outside of the gas stove body 400, which is convenient for users to operate the first handle 210 and the second handle 220 from the outside.
[0046] Furthermore, the connector 100 may be fixed to the bottom shell 410 of the gas stove body 400 , and an opening 420 may be provided at the bottom of the bottom shell 410 , through which the first handle 210 and the second handle 220 may extend to the outside of the gas stove body 400 .
[0047] In some embodiments, Figure 5 As shown, a cover 430 can be further provided on the gas stove body 400, and the cover 430 can be opened or closed. When the cover 430 is closed, the burner, the pot rack and other structures can be covered inside to provide dust protection. When the cover 430 is opened, the burner, the pot rack and other structures are exposed to allow the user to use the gas stove normally.
[0048] The terms and words used in the above description and claims are not limited to the literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the utility model. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the utility model is provided only for illustration, and not for limiting the utility model as defined by the attached claims and their equivalents.
