Improvement of driving device of safety protector for stove (2)

This creation relates to the improvement of the driving device of a safety protector for stoves, especially a simple set-up, easy operation and easy use, which can surely and effectively improve the safety of stoves, and is extremely practical, ideal and Drive for progressive safety guards for stoves.

Press, including gas stoves or electric stoves are necessary equipment for the kitchen, whether it is cooking or boiling water can not be without it.

In addition, in the cooking process of stoves, empty or dry-burning containers or cooking utensils are caused by human carelessness, which has led to fires. It is also frequently heard, for example, workers carry out boiling water or stew food. Time, because it takes a long time, usually do n’t stay in the kitchen all the time, but sometimes leave the kitchen or use this space to handle other things, for this reason, it often happens that staff forget that the kitchen stove is being cooked Work, and because of the long time, the dangerous situation of empty burning, dry burning containers and pots.

For this reason, there is a gas stove protection device for preventing the dry burning of containers or pots, which is mainly used by containers or pots containing liquids. After a long period of cooking, the liquid evaporates to a set weight. When this value is reached, the gas source will be shut down, which can prevent the container or pot from burning out or dry burning. However, since the type, material and size of the container or pot used by each person are not the same, the weight after they contain the liquid is also different. The weight of the container or pot that contains the liquid drops to the set value, that is, the control method and protective measures for shutting down the gas. For a container or pot that has a large weight, it has obvious poor applicability, inaccuracy and even Disadvantages of inability to use, in particular, the protective device that cannot be applied to all containers and pans in one piece, will also cause inconvenience and inconvenience to consumers due to their limited scope of use.

In order to improve the above-mentioned defects, the creator also provided the "safety protector for stoves" in the patent case No. M554154. As shown in the first and second figures, it is mainly provided with a device at the ignition switch shaft of the stove. Safety guard with warning and forced closing function; the safety guard includes a main body 10 and a driving device 20, a knob 30, and an electronic control device 40 mounted on the main body 10; wherein the driving device 20 is provided with a driving gear 2011 The main body 10 is rotated by a driving motor 202 and a driving gear 2012; the knob 30 is inserted into the through hole 101 of the main body 10, and is combined with the driving gear 2011 and the ignition switch shaft 50 fixed to the stove; According to this, when turning the knob 30 to perform the stove ignition and cooking operation, the driving gear 2011 and the driving gear 2012 of the transmission assembly 201 of the driving device 20 will be driven to rotate, and the electronic control device 40 will be started to time, When the cooker is not turned off at the predetermined cooking time, the electronic control device 40 will issue a beeping alarm, and then, at the set time, the driving device 20 will drive the knob 30 to rotate backward to force Closed fire action, and the heir, can do to improve the safe use of stoves effect and purpose.

As mentioned above, since the safety protector for the stove is installed and used with the ignition switch shaft 50 of a general stove, the volume must be made into a small form that does not take up space. Therefore, the volume of the body 10 is limited and cannot be expanded. The driving motor 202 and the transmission assembly 201 of the driving device 20 installed on the main body 10 will also be unable to increase and become smaller.

In addition, because the stove implements the ignition action, the staff uses the hand to turn the knob 30. It is completed by applying a large turning torque. Therefore, when the driving device 20 intends to turn the knob 30 in the reverse direction to perform a forced closing of the furnace fire, the driving device 20 also needs a large torque to achieve; that is, Since the driving gear 2012 in the driving device 20 meshing with the driving gear 2011 is directly installed and fixed on the rotating shaft 2021 of the driving motor 202, in order to drive the knob 30 to rotate in the reverse direction, the driving motor 202 must be made into The larger volume has greater torque; however, as mentioned above, in the case where the volume of the body 10 has been limited and cannot be expanded, and the volume of the drive motor 202 is constrained and cannot be effectively increased, in practice, the stove described above The use of a safety protector often causes insufficient torque, and the reverse rotation of the knob 30 is unstable and unstable.

The reason is that in order to improve the above-mentioned shortcomings and make the use of the safety protector for stoves more effective, the creators carefully studied and cooperated with the use of science to finally provide this creation.

That is, the main purpose of this creation is to provide a drive device improvement for a safety protector for stoves, which can improve the above-mentioned shortcomings, and enable stoves to effectively prevent the phenomenon of dry-burning, empty-burning containers or pots, thereby achieving improvement. The effect of stove safety.

After installing the safety protector for the cooking stove on the shaft of the ignition switch of the cooking stove, please match the twelfth to nineteenth illustrations. When the stove does not perform the ignition and cooking operation, the knob 30 When it is at the origin position (see the twelfth figure), the driving body 203 of the driving device 20 will not move, and the clutch element 205 will cause the second latching tooth 2051 to cause a tooth due to the elastic force of the return element 207. The bottom 20510 corresponds to the tooth top 20410 of the first latching tooth 2041 abutting the first driving member 204. At the same time, the clutch member 205 will also be elastically stretched by the returning element 207 and will not engage with the second driving member 206. The driving gear 2062 of the driving member 206 is free to rotate and meshes with the driving gear plate 20111. Then, the cooking operation is performed, and the electronic control device 40 (see the eleventh figure) of the safety protector for the cooking stove is set for cooking time. When the knob 30 is turned to ignite the stove, and the driving gear 2011 is rotated together (see the thirteenth figure), the driving body 203 of the driving device 20 is kept in a stationary state; since the second driving member 206 is Continue to mesh with the driving gear 2011 in a freely rotating form, so the action of turning the knob 30 will be smooth and will not be disturbed at all; then, when turning the knob 30 to adjust the size of the fire (see Figure 14) ), Due to the driving body 2 of the driving device 20 03 is still inactive, and the second driving member 206 is still engaged with the driving gear 2011 in a freely rotating form, and the action of the turning knob 30 will still have a smooth operation effect.

Next, when the set cooking time has expired and the knob 30 of the stove has not been turned off by the worker, the driving body 203 of the driving device 20 will be automatically activated (see FIG. 15), and the first driving The member 204 is driven to rotate; since the tooth bottom 20510 of the second latching tooth 2051 of the clutch member 205 originally elastically abuts the tooth top 20410 of the first latching tooth 2041 of the first driving member 204, it becomes the first When the driving member 204 rotates, the tooth top 20410 of the first latching tooth 2041 of the first driving member 204 will move upward along the inclined shifting portion 20511 of the second latching tooth 2051 of the clutch member 205 (see section (Picture 16), and in the displacement one by one, the clutch member 205 is moved forward, and the clutch member 205 gradually approaches the direction of the second driving member 206; then, when the first latching tooth 2041 of the first driving member 204 is rotated, The tooth tip 20410 moves up along the inclined push portion 20511 of the second latching tooth 2051 of the clutch member 205 When the stopper 20512 is positioned (see the seventeenth figure), the first driving member 204 and the clutch member 205 will complete the latching action with each other. The clutch member 205 can rotate with the first driving member 204 at the same time. The clutch member 205 that is moved forward will also cause the third latching tooth 2052 on the other side and the fourth latching tooth 2061 of the second driving member 206 to latch with each other. Therefore, since the driving gear 2062 of the second driving member 206 meshes with the driving tooth plate 2011 at any time, the rotating second driving member 206 can drive the driving tooth plate 2011 one by one, and is combined with the driving tooth plate 2011 as The integrated knob 30 rotates and resets together to make the action of forcibly closing the fire (see Fig. 18); according to this, when the knob 30 is driven by the driving device 20 to rotate in the reverse direction to perform the action of forcibly closing the fire (see Fig. 19), Through the control of the electronic control device 40, the driving body 203 of the driving device 20 rotates in the reverse direction, and the tooth top 20410 of the first latching tooth 2041 of the first driving member 204 is separated from the second latching tooth 2051 of the clutch member 205. The blocking portion 20512 is arranged along the inclined shifting portion 20511 of the second latching tooth 2051. Sliding to the tooth bottom 20510, the clutch member 205 can naturally and smoothly disengage the third latching tooth 2052 from the fourth latching tooth 2061 of the second driving member 206 under the elastic force of the return element 207. The second driving member 206 is restored to the free rotation state, thereby facilitating the operation of turning the knob 30 times.

As described above, the driving body 203 of the driving device 20 implements the control of the reverse rotation, and it can also be pressed by the induction flange 20112 of the driving gear 2011 to the induction switch 104 preset in the body 10; that is, as in the nineteenth As shown in the figure, when the knob 30 and the driving gear 2011 are driven to rotate in the reverse direction by the driving device 20 to perform a forced closing of the fire, the induction flange 20112 of the driving gear 2011 will return to the original position when the knob 30 is rotated. The contact switch is pressed against the induction switch 104 installed on the body 10, and then the induction switch 104 will immediately control the driving body 203 of the driving device 20 to rotate in the reverse direction through the electronic control device 40. The tooth top 20410 of one latching tooth 2041 is separated from the stop portion 20512 of the second latching tooth 2051 of the clutch member 205. Naturally, the clutch member 205 can be actuated by the returning element 207 to release the second driving member 206 in a timely manner. The second driving member 206 immediately returns to the free-running idling form to engage with the driving gear 2011, and the knob 30 can be smoothly made according to this. Ready and operational functions for one turn.

That is, through the cooperation of the driving body 203, the first driving member 204, the clutch member 205, the second driving member 206, the returning element 207, and the driving gear 2011 of the creative driving device 20, the stove implements cooking ignition or adjusting fire power At this time, the knob 30 can be smoothly operated; when the cooking time is up and the user does not turn off the stove, the knob 30 can be turned in the opposite direction, which is sure, smooth, stable, and stable. Action, to achieve the effect of reliable and effective use of stoves.

In other words, using this creation will have at least the following advantages:

1. Simple to set up and economical.

2. The knob can be turned in the reverse direction to forcibly close the fire, which is more smooth, reliable, stable and stable. .

3. It can surely and effectively improve the safety of stove use.

In summary, the improvement of the drive device for the safety protector for stoves is obviously more effective than conventional ones. Although the device and structure are not complicated and cumbersome, the overall operation concept is deep. It is rich in specificity and is an application that has not been seen in the same type of products. Therefore, it has already met the requirements of "newness and progress" for new patent applications. I invite the reviewing committee to review and grant the patent. prayer.

However, the above description is only a preferred embodiment of this creation. Any changes and modifications of effects made in accordance with the spirit of this creation should still be included in the scope of the patent application for this creation.
