[0031] In this embodiment, the magnetic key 1 is applied to the gas stove scenario. Here, the gas stove can be devices such as a gas fireplace or a gas stove. The magnetic key is used to control the gas stove to perform gas adjustment operations, thereby adjusting the combustion efficiency and the flame size. When using the gas stove, insert the magnetic key 1 into the gas stove. By rotating the magnetic key 1 to change the opening and closing state of the gas adjustment hole, the flame size and combustion efficiency in the gas stove can be controlled. The larger the opening of the valve, the more gas is allowed to pass through, and the larger the flame generated by the burner. Conversely, the smaller the flame. Correspondingly, the outer shell of the gas stove is made of metal. The key rod 11 is the main part of the magnetic key 1, and the magnetic attraction part 12 is used to magnetically adsorb the outer shell of the gas stove. Further, the magnetic attraction part 12 can be made of materials such as magnets or magnetic sheets here. The shape of the magnetic attraction part 12 is not limited here and can be set according to specific circumstances.

[0032] In the technical solution of the present utility model, when using the gas stove, insert the magnetic key 1 into the stop valve of the gas stove. The magnetic key 1 is used to adjust the combustion efficiency and the flame size of the gas stove. When the use is completed, the magnetic key 1 is separated from the gas stove. By adding the magnetic attraction part 12 to the original key and utilizing the magnetic adsorption effect of the magnetic attraction part 12, the key rod 11 can be adsorbed on the shell of the gas stove, completing the storage of the key. This method not only reduces the phenomenon of key loss but also helps to complete the storage and arrangement of the key.

[0033] In the embodiment of the present utility model, an installation groove 112 is opened at one end of the handle 111 close to the key rod 11.

This setting method not only increases the adsorption ability but also increases the safety. And the magnetic attraction part 12 is arranged in the installation groove 112, which also makes the overall appearance of the key more tidy and improves the aesthetics.

[0034] In an embodiment of the present utility model, the handle 111 is provided with at least two placement grooves 112, the magnetic key 1 includes at least two magnetic attraction parts 12, and the handle 111 has two opposite surfaces; each placement groove 112 is respectively distributed on the two surfaces of the handle 111, and the magnetic attraction part 12 is bonded to the inner wall of a placement groove 112. In this embodiment, in order to enable the key to have a magnetic adsorption effect in all directions, at least two placement grooves 112 are provided and at least two magnetic attraction parts 12 are provided in cooperation. The placement groove 112 is a blind groove here, and the two placement grooves 112 are not connected to each other. Correspondingly, the magnetic attraction part 12 is bonded to the inner wall of the placement groove 112 through an adhesive to ensure stability on the handle 111. The adhesive here can be made of materials such as a strong adhesive, and any material that can achieve the bonding function is acceptable, without limitation. The above setting method not only improves the overall symmetry of the key, but also reduces the risk of detachment caused by vibration or impact, and improves durability.

[0035] In an embodiment of the present utility model, the placement groove 112 includes at least one groove, and the magnetic attraction part 12 is provided with at least one protrusion adapted to the groove, and each protrusion is inserted into a groove. In this embodiment, in order to facilitate the user to replace or maintain the magnetic attraction part 12, the magnetic attraction part 12 is detachably connected to the placement groove 112. Through the plug-in design of the groove and the protrusion, the mechanical connection between the magnetic attraction part 12 and the placement groove 112 is realized, ensuring the precise positioning of the magnetic attraction part 12 in the placement groove 112. This setting method is easy to operate and also ensures the stability of the structure.

[0036] In an embodiment of the present utility model, the placement groove 112 is arranged along the circumferential direction of the handle 111, and the placement groove 112 further includes at least one fastening hole for placing a fastener to fix the magnetic attraction part 12. In this embodiment, in order to provide a more balanced adsorption force, the fastening hole is a reserved hole position in the placement groove 112 for fixing the magnetic attraction part 12. The fastener here can be a screw, a bolt, etc., without limitation. This setting method ensures the uniform distribution of the magnetic attraction parts 12 on the handle 111, and at the same time prevents the magnetic attraction parts 12 from loosening or falling off during use, improving the stability of the overall structure.

In this embodiment, the unlocking part 13 is a key component for actually operating the gas regulation of the gas stove with the magnetic key 1. The cylindrical unlocking part 13 realizes unlocking or locking through rotational operation, and this setting method is more convenient to operate.

[0038] In an embodiment of the present utility model, an unlocking groove 131 is formed at one end of the unlocking portion 13 away from the key rod 11. A limiting step is provided along the extending direction of the inner peripheral wall of the unlocking groove 131. The cross-sectional area of the unlocking groove 131 gradually decreases from one end close to the bottom of the unlocking groove 131 to one end close to the opening of the unlocking groove 131. In this embodiment, the unlocking groove 131 is used for mating connection with the gas regulation hole of the gas stove, and the limiting step is used for matching the valve of the gas stove. Please refer to Figure 2 and Figure 4 , in the figure, there is one limiting step provided for the unlocking groove, and the number of limiting steps can be set to multiple according to requirements; further, multiple limiting steps are provided for the unlocking groove.

The existence of the marking portion helps the user to quickly recognize and select. Through the marking portion, the usage instructions or warnings of the handle 111 can also be clearly displayed, improving the correct operation of the user and reducing the risk of misoperation. The existence of the keyhole 14 helps to further prevent the key from being lost. When the gas stove is not made of metal and the magnetic attraction function of the magnetic attraction portion 12 cannot play a role at this time, due to the existence of the keyhole 14, it can be hung on one side of the gas stove to prevent loss. Further, the cooperation of the keyhole 14 and the magnetic attraction portion 12 can be applied to a variety of scenarios. With the dual setting, the key can be fixed more firmly, reducing the risk of loss caused by accidental dropping or forgetting.

[0041] The present utility model further provides a gas stove, which includes a magnetic attraction key 1 and a housing. The specific structure of the magnetic attraction key 1 refers to the above embodiment. Since this gas stove adopts all the technical solutions of the above all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one. Among them, for the housing, the magnetic attraction key 1 is adsorbed on the housing.

[0042] In this embodiment, the gas stove can be a gas fireplace, a gas stove and other gas equipment, and the housing of the gas stove is made of metal, stainless steel and other materials. Correspondingly, when the housing is made of metal, it can interact with the magnetic part 12 of the magnetic key 1 to generate an attractive force; when the housing is made of non-magnetic materials such as stainless steel, the magnetic part 12 of the magnetic key 1 cannot act on the housing, and the magnetic key 1 can be fixed near the housing by passing a hook through the key hole 14. A gas adjustment hole for cooperating with the magnetic key 1 is provided on one side of the housing. The magnetic key 1 is connected to the gas adjustment hole through the unlocking part 13 and controls the flame size and combustion efficiency of the gas stove. The above method completes the induction and arrangement of the keys and avoids the occurrence of loss.
