Description

Technical Field

[0001] This utility model relates to a self-locking structure for an anti-dry-burning probe. Background Technology

[0002] Most burner heads on the market have an anti-dry-burning probe located in the middle. This probe monitors the temperature of the cookware to determine if it is dry-burning, thus mitigating the safety hazards caused by dry burning. However, in actual use, it has been found that due to the wide variety of cookware available and the different shapes of their bottoms, the anti-dry-burning probe sometimes misjudges the temperature, affecting the user's cooking experience. In such cases, users can only choose to replace the burner head or remove the anti-dry-burning probe, but either option will cause inconvenience.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] To solve the above problems, this utility model proposes a self-locking structure for an anti-dry-burning probe, which allows users to stop the operation of the anti-dry-burning probe.

[0005] This utility model proposes a self-locking structure for an anti-dry-burning probe, which includes a vertical rod, a probe body, and a spring. The probe body is located at the top of the vertical rod, and the spring is located inside the probe body and abuts against the vertical rod. The probe body can extend and retract relative to the vertical rod with the help of the spring. A locking ring is provided on the vertical rod, and the locking ring has a snap-fit ​​structure. The snap-fit ​​structure includes a vertically extending sliding groove and a horizontally extending transverse groove. The transverse groove is connected to the vertical groove and has a locking slot. The probe body has a protrusion that cooperates with the sliding groove. The protrusion can enter the locking slot through the transverse groove and restrict the extension and retraction of the probe body.

[0006] In one or more embodiments, the protrusion is a vertically extending rib, the top of which engages with a bayonet to restrict the extension and retraction of the probe body.

[0007] In one or more embodiments, the locking ring is provided with a plurality of snap-fit ​​structures, which are circumferentially distributed on the outer peripheral wall of the locking ring, and the probe body is provided with protrusions corresponding to the number of snap-fit ​​structures.

[0008] In one or more embodiments, the locking ring is disposed on the outer side wall of the upright, the bottom of the probe body is provided with a protrusion that abuts against the bottom of the locking ring, and the spring members abut against the probe body and the locking ring respectively.

[0009] In one or more embodiments, the locking ring is fixed to the upright by welding; or, the locking ring is fixed to the upright by riveting.

[0010] In one or more embodiments, the pole is a hollow structure, and the signal wires of the probe body can pass through the inside of the pole.

[0011] The beneficial effects of this utility model are: the anti-dry-burning probe has a self-locking structure, which can be manually operated by the user to put the anti-dry-burning probe into a self-locking state, so that the anti-dry-burning probe cannot come into contact with the pot, thus stopping the use of the anti-dry-burning probe. Attached Figure Description

[0012] Figure 1 This is a cross-sectional view of the anti-dry-burning probe of this utility model embodiment; Figure 2 This is a schematic diagram of the locking ring structure according to an embodiment of the present invention. Detailed Implementation

[0013] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0014] Please refer to the appendix. Figure 1-2 This utility model provides a self-locking structure for an anti-dry-burning probe, comprising a support rod 1, a probe body 2, and a spring 3. The probe body 2 is located at the top of the support rod 1, and the spring 3 is located inside the probe body 2 and abuts against the support rod 1. The probe body 2 can extend and retract relative to the support rod 1 with the aid of the spring 3. A locking ring 4 is provided on the support rod 1, and the locking ring 4 has a snap-fit ​​structure, which includes a vertically extending sliding groove 5 and a horizontally extending transverse groove 6. The transverse groove 6 is connected to the vertical groove 5 and has a locking slot 7. The probe body 2 has a protrusion that cooperates with the sliding groove 5. 8. The protrusion 8 can enter the bayonet 7 through the transverse groove 6 and restrict the extension and retraction of the probe body 2. Specifically, the user presses the probe body down to its lowest position, at which point the top of the protrusion corresponds to the transverse groove 6. Then, the user rotates the probe body so that the protrusion enters the transverse groove and aligns with the bayonet. Upon releasing the hand, the probe body springs upward under the elastic force of the spring. At this time, the protrusion, under the elastic force of the spring, first enters the bayonet. After entering the bayonet, the protrusion is restricted by the bayonet, preventing the probe body from springing up, thus storing the anti-dry-burning probe and preventing it from contacting the cookware, thus stopping the anti-dry-burning probe from working. When it is necessary to reuse the probe, simply press the probe body down again, then reverse the probe body so that the protrusion disengages from the bayonet and enters the vertical groove along the transverse groove. Releasing the hand will then allow the probe body to spring up again.

[0015] The protrusion 8 is a vertically extending rib. The top of the rib engages with the bayonet 7 to restrict the extension and retraction of the probe body 2. The vertically extending rib ensures that it always maintains a sliding fit with the vertical groove, which is beneficial for users to lock or unlock the probe body and eliminates the need for alignment steps.

[0016] The locking ring 4 is provided with multiple snap-fit ​​structures, which are circumferentially distributed on the outer peripheral wall of the locking ring 4. The probe body 2 is provided with protrusions 8 corresponding to the number of snap-fit ​​structures. The multiple snap-fit ​​structures and protrusions cooperate with each other to ensure that the probe body can extend and retract freely and maintain a self-locking state when self-locking, and will not be easily disengaged from the self-locking state by external forces.

[0017] The locking ring 4 is located on the outer side wall of the upright 1. The bottom of the probe body 2 is provided with a protruding step 9 that abuts against the bottom of the locking ring 4. The spring member 3 abuts against the probe body 2 and the locking ring 4 respectively. The abutting between the protruding step and the bottom of the locking ring can prevent the probe body from coming loose from the upright.

[0018] The locking ring 4 is fixed to the upright 1 by welding; or the locking ring 4 is fixed to the upright 1 by riveting. The specific fixing method can be selected according to actual needs, and there is no restriction here.

[0019] The pole 1 has a hollow structure, and the signal line 10 of the probe body 2 can pass through the inside of the pole 1, making full use of the internal space of the pole.

[0020] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
