Referring to fig. 1 to 9, an embodiment of the present application discloses a control device, which includes a fixed portion 200, a movable portion 300, an activation portion 310, and at least two functional circuits. The control device can be applied to the gas stove to control the gas stove to realize various functions.

The fixing portion 200 is disposed on the panel 100 of the gas stove and located on a side of the panel 100 of the gas stove opposite to the inside of the gas stove. The movable portion 300 is movably disposed at a side of the panel 100 of the gas range facing away from the inside of the gas range, such that the movable portion 300 is movable, so that the relative positional relationship between the movable portion 300 and the fixing portion 200 can be changed.

Specifically, a functional circuit for controlling the timing closing of the gas stove, a functional circuit for controlling the timing change of the fire intensity of the gas stove, a functional circuit for controlling the flame generation position of the gas stove, and the like can be provided, and the specific functions of the functional circuits are not limited in the present application.

The two functional circuits form contacts corresponding to the functional circuits on the fixing portion 200, and the number of the contacts corresponds to the number of the functional circuits. The activation portion 310 is disposed on the movable portion 300, so that in the process that the movable portion 300 moves relative to the fixed portion 200, the activation portion 310 can also move along with the movable portion 300, and in the process that the movable portion 300 drives the activation portion 310 to move, the activation portion 310 can act on a contact of any one of the at least two functional circuits, so that the functional circuit is activated, and the gas stove can further realize a function corresponding to the functional circuit. The movement of the movable portion 300 may bring the activating portion 310 to act on the contacts of the different functional circuits, so that the different functional circuits are activated.

It should be understood that the control device of the present application may be provided with a circuit board, and in particular, at least two functional circuits may be provided on the circuit board, the circuit board may be provided inside the gas stove, and the circuit board may be provided with a conductive wire corresponding to the plurality of functional circuits, and one end of the conductive wire may extend through the panel 100 to the fixing portion 200 to form a contact.

In the process of adjusting the movable part 300 to move relative to the fixed part 200, since the movable part 300 and the fixed part 200 are both disposed on the side of the panel 100 of the gas range facing away from the inside of the gas range, the fixed part 200 and the movable part 300 can be conveniently mounted on the panel 100 of the gas range without disposing the fixed part 200 and the movable part 300 inside the gas range, so that the process of mounting and dismounting the fixed part 200 and the movable part 300 is simple and convenient.

In the control device of the embodiment of the application, the fixed portion 200 and the movable portion 300 are disposed on the panel 100 of the gas stove, and the movable portion 300 can move relative to the fixed portion 200, so that the activating portion 310 connected to the movable portion 300 can move along with the movable portion 300, and thus the activating portion 310 can act on a contact of any functional circuit on the fixed portion 200, and can activate the functional circuit to control the gas stove to realize different functions, thereby achieving the purpose of simplifying the control mode of the gas stove. The fixed portion 200 and the movable portion 300 are both disposed on a side of the panel 100 facing away from the gas stove, so that the fixed portion 200 and the movable portion 300 do not need to be mounted inside the gas stove, the fixed portion 200 and the movable portion 300 are convenient to mount, and the fixed portion 200 and the movable portion 300 are also convenient to clean.

In some embodiments, in order to make the structure compact when the movable part 300 and the fixed part 200 are provided on the panel 100 of the gas range, the movable part 300 may be provided to be sleeved on the fixed part 200, and the movable part 300 may rotate around the fixed part 200. The contacts of at least two functional circuits formed on the fixing portion 200 can be disposed on different portions of the outer peripheral wall of the fixing portion 200 facing the movable portion 300, and correspondingly, the activating portion 310 can be disposed on an inner wall of the movable portion 300 facing the fixing portion 200, and during the rotation of the movable portion 300 relative to the fixing portion 200, the activating portion 310 can rotate with the movable portion 300, so that the activating portion 310 can act on the contacts of different functional circuits on the outer peripheral wall of the fixing portion 200, so that the different functional circuits can be activated.

Specifically, after the activation portion 310 is disposed on the movable portion 300, a side of the activation portion 310 facing away from the movable portion 300 may be disposed to contact with an outer peripheral wall of the fixing portion 200, and an end of the activation portion 310 may rotate along the outer peripheral portion of the fixing portion 200 during the movement of the movable portion 300 until the end rotates to contact with a contact of any functional circuit, so that the functional circuit is activated.

The activation part 310 acts on the contact of each functional circuit by rotating the movable part 300 around the fixing part 200, so that the movable part 300 does not move along the panel 100 of the gas stove and the relative position relationship between the movable part 300 and the panel 100 of the gas stove does not change in the position change process of the activation part 310, and the purpose of reducing the space of the panel 100 of the gas stove occupied by the movable part 300 is achieved, thereby enabling the structure of the control device of the present application to be more compact.

Of course, in other embodiments, the movable portion 300 may be further disposed to be movable in a preset direction with respect to the panel 100 of the gas range, the preset direction may be a linear direction, and accordingly, the movable portion 300 may be disposed at one side of the fixed portion 200, contacts of the functional circuits may be distributed in the fixed portion 200 in the preset direction, and the activating portion 310 may be movable along the movable portion 300 in the preset direction, so that one end of the activating portion 310 may act on the contacts of each of the functional circuits distributed in the preset direction in a process of moving in the preset reverse direction.

Specifically, in this embodiment, the contacts of the functional circuits may be disposed on the outer wall of the fixed part 200 facing the movable part 300, one end of the activation part 310 may be disposed to be connected to the outer wall of the movable part 300 facing the fixed part 200, and the other end of the activation part 310 may be disposed to be in contact with the outer wall of the fixed part 200 facing the movable part 300, so that the activation part 310 moves in a predetermined direction to make the activation part 310 contact with the contacts of the respective functional circuits, thereby making the activation part 310 activate the functional circuits.

By the above arrangement of the movable part 300, the movable part 300 can be moved relative to the panel 100 of the gas range, so that the change in the positional relationship between the movable part 300 and the fixed part 200 can be clearly observed, thereby making the way in which the user operates the movable part 300 more intuitive. Particularly, in an environment where the ambient light is weak, the user can select different functions by adjusting the positional relationship between the movable portion 300 and the fixed portion 200 in a blind operation manner.

In some embodiments, in order to form contacts on the fixing portion 200 for each functional circuit, the control device of the present application may further include a resistor sheet 210, the resistor sheet 210 may be disposed around the peripheral wall of the fixing portion 200, the contacts of the functional circuit are located on the resistor sheet 210, the activating portion 310 may employ an electrical connector, an end of the activating portion 310 facing away from the movable portion 300 may be disposed to contact the resistor sheet 210, and an end of the activating portion 310 facing away from the movable portion 300 may contact each portion of the resistor sheet 210 during the movement of the activating portion 310 with the movable portion 300, so that different functional circuits are activated.

Specifically, in the process that the activation portion 310 rotates along the resistance sheet 210, the activation portion 310 contacts with different parts of the resistance sheet 210, so that the parts of the resistance sheet 210 contacting with the activation portion 310 have different resistance values.

In addition, in other embodiments, the control device of the present application may further include a hall sensor and a function selection circuit, the activation portion 310 may be a magnetic component, the function selection circuit is electrically connected to both the hall sensor and the plurality of functional circuits, and the hall sensor may be disposed on the fixing portion 200, and specifically, may be integrated inside the fixing portion 200. In the process that the magnetic part moves along with the movable part 300, the magnetic field formed by the magnetic part changes along with the magnetic part, so that the Hall sensor can detect different magnetic field signals, the function selection circuit can activate different function circuits according to different magnetic field signals, and the purpose of controlling various functions of the gas stove can be achieved.

Therefore, the contact of the functional circuit can be understood as that the magnetic member is at different positions, and the magnetic field signal detected by the hall sensor when the magnetic member is at different positions can correspond to different functional circuits, so as to realize the activation selection of the functional circuits.

In some embodiments, the contact of the functional circuit of the present application may be further configured as a micro switch, and the activation portion 310 may be configured as an electrical connector, specifically, a metal sheet, and by moving the movable portion 300, the activation portion 310 may be brought into contact with the micro switch of the different functional circuit, so as to achieve the purpose of enabling the micro switch to be turned on and the functional circuit to be activated.

When a microswitch is provided on the stationary portion 200, the connector 260 may be in communication with the microswitch, or other electrical connection on the stationary portion 200, so that the functional circuitry may form contacts on the stationary portion 200.

In some embodiments, in order to facilitate the rotation of the movable portion 300, so that the movable portion 300 can rotate relative to the fixing portion 200, the movable portion 300 may further include a grip ring 330, the grip ring 330 is sleeved on the movable portion 300, and a plurality of grooves may be disposed on a circumferential outer wall of the grip ring 330, so that when a user rotates the grip ring 330, friction may be increased, so as to facilitate the rotation of the grip ring 3300 and the movable portion 300 connected to the grip ring 330. Of course, the outer circumferential wall of the grip ring 330 may be provided with protrusions to facilitate rotation by the user.

Of course, in order to further reliably fix the fixing portion 200 to the panel 100, the fixing portion 200 may be fixed to the panel 100 of the gas stove by an adhesive method, and correspondingly, the protrusion 220 may also be fixed to the positioning hole 110 by an adhesive method, so that the fixing portion 200, the protrusion 220 and the panel 100 of the gas stove do not need to be separately provided with a fixed connection structure, thereby simplifying the structure of the control device of the present application.

In addition, the above positioning hole 110 may be provided as a through hole penetrating the panel 100 of the gas range, such that the positioning hole 110 may be passed through by a wire, so that the wire on the circuit board may extend through the positioning hole 110 to be connected with the fixing portion 200.

It should be understood that the valve stem 400 of the gas stove is a mechanism for adjusting the fire of the gas stove, the fire of the gas stove can be changed by rotating the valve stem 400 of the gas stove, one end of the valve stem 400 is located at a side of the panel 100 of the gas stove, which faces away from the interior of the gas stove, so that a user can operate to rotate the valve stem 400, the other end of the valve stem 400 extends to the interior of the gas stove and is connected with the fire adjusting mechanism of the gas stove, therefore, the valve stem 400 can penetrate through the panel 100 of the gas stove, and a through hole for the valve stem 400 to penetrate through is also formed on the panel 100 of the gas stove.

The through hole for the valve rod 400 to pass through on the panel 100 of the gas stove can be the positioning hole 110, therefore, the positioning hole 110 can pass through the conducting wire of the circuit board and also can pass through the valve rod 400 of the gas stove, so that the panel 100 of the gas stove does not need to additionally and separately provide through holes for the valve rod 400 of the gas stove and the conducting wire to pass through.

The fixing portion 200 may be sleeved on the valve stem 400 of the gas range, so that the fixing portion 200 should be provided with a through hole for the valve stem 400 of the gas range to pass through, and the through hole may be specifically arranged at a central portion, specifically the central hole 240, of the fixing portion 200. The inner diameter of the central hole 240 of the fixing part 200 may be set to be greater than the outer diameter of the valve stem 400 of the gas range, such that a certain gap may be provided between the inner wall of the central hole 240 of the fixing part 200 and the outer wall of the valve stem 400 of the gas range, when the valve stem 400 of the gas range is rotated to adjust the fire of the gas range, the fixing part 200 may not rotate with the valve stem 400 of the gas range, and the fixing part 200 may not cause resistance to the rotation of the valve stem 400 of the gas range, thereby making the fire adjustment of the gas range smoother.

The fixing portion 200 is sleeved on the valve rod 400 of the gas stove, so that the fixing portion 200 can make full use of the part for installing the valve rod 400 on the panel 100 of the gas stove, and the through hole for the valve rod 400 of the gas stove to pass through on the panel 100 of the gas stove is used for forming the positioning hole 110, so that the through hole can enable the lug 220 of the fixing portion 200 to be embedded in the through hole and can enable a lead of a circuit board to pass through.

In some embodiments, the control device of the present application is disposed on a gas stove, the gas stove may further include a fire adjusting knob 410, the fire adjusting knob 410 may be disposed to be connected to a valve stem 400 of the gas stove, specifically, the valve stem 400 of the gas stove has a first end located inside the gas stove and a second end extending to a side of the panel 100 of the gas stove opposite to the inside of the gas stove, and the fire adjusting knob 410 may be connected to an end of the valve stem 400 of the gas stove extending to a side of the panel 100 of the gas stove opposite to the inside of the gas stove, that is, connected to the second end of the valve stem 400, so that a user may rotate the valve stem 400 of the gas stove by rotating the fire adjusting knob 410, thereby achieving an objective of adjusting the fire of the gas stove.

Specifically, the second end of the valve rod 400 passes through the central hole 240 of the fixing portion 200 and extends out of the fixing portion 200, the fire power adjusting knob 410 is a cover-shaped structural member, and the fire power adjusting knob 410 can be arranged to have a certain gap with both the fixing portion 200 and the movable portion 300, so that the fire power adjusting knob 410, the fixing portion 200 and the movable portion 300 are in a non-contact state, when the fire power adjusting knob 410 is rotated, the movable portion 300 can be prevented from rotating along with the fire power adjusting knob 410, and the fixing portion 200 cannot cause resistance to the fire power adjusting rotation. Similarly, the movable portion 300 does not drive the fire power adjusting knob 410 to rotate in the process that the movable portion 300 rotates relative to the fixed portion 200, so that the fire power adjustment and the function selection of the gas stove using the control device of the present application are not affected.

In addition, the area of the end surface of the fire power adjusting knob 410 facing the fixing part 200 may be set to be not smaller than the sectional area of the hole of the center hole 240 of the fixing part 200, so that the fire power adjusting knob 410 may shield the center hole cover of the fixing part 200 to shield the center hole 240 of the fixing part 200, thereby preventing foreign matter from entering the gas range through the center hole 240 of the fixing part 200. And, the fire power adjusting knob 410 and the valve stem 400 of the gas range may be detachably connected, and when the fixing part 200 needs to be cleaned, the fixing part 200 may be exposed by detaching the fire power adjusting knob 410 from the valve stem 400, so that the user can clean the fixing part 200.

Because the first blocking piece 230 and the second blocking piece 411 are respectively disposed on the fixing portion 200 and the fire adjusting knob 410, the first blocking piece 230 is sleeved in the second blocking piece 411, a gap is formed between the first blocking piece 230 and the second blocking piece 411, and an opening of the gap faces the fixing portion 200, foreign matters on one side of the gas stove panel 100, which faces away from the interior of the gas stove, cannot enter the fixing portion 200 through the gap between the first blocking piece 230 and the second blocking piece 411, so as to prevent the foreign matters from entering the interior of the gas stove.

In some embodiments, it is understood that when the movable portion 300 moves relative to the fixed portion 200, the activating portion 310 can be driven to move along with the movable portion 300, the activating portion 310 can be located at different positions to act on different contacts of the functional circuit, and the activating portion 310 needs to be kept stable after the activating portion 310 acts on the contacts electrically connected to the contacts of the functional circuit, so that the contacts of the functional circuit and the activating portion 310 have a good electrical connection effect.

Therefore, the control device of the present application is further provided with the elastic element 250, the inner wall of the movable portion 300 facing the fixed portion 200 can be provided with a plurality of positioning grooves 320 arranged along the circumference of the movable portion 300, one end of the elastic element 250 is connected with the fixed portion 200, and the other end of the elastic element 250 can be embedded into the positioning grooves 320 of the movable portion 300, so that after the movable portion 300 rotates relative to the fixed portion 200, one end of the elastic element 250 can be respectively embedded into each positioning groove 320 of the movable portion 300, and after one end of the elastic element 250 is embedded into one positioning groove 320 of the movable portion 300, the elastic element 250 can limit the movable portion 300, so as to prevent the movable portion 300 from continuing to rotate under the condition of no external force or small external force action.

Specifically, the positioning grooves 320 of the movable portion 300 may be disposed at positions corresponding to contacts of each functional circuit, and when one end of the elastic member 250 is inserted into one positioning groove 320, the activating portion 310 acts on the contact of one functional circuit, and if a user needs to switch the function of the gas range, a large force needs to be applied to the elastic member 250 to compress the elastic member 250, so that the distance between one end of the elastic member 250 and the positioning groove 320 of the movable portion 300 is increased, and one end of the elastic member 250 is separated from the positioning groove 320. When the movable portion 300 rotates to another positioning slot 320 to be opposite to one end of the elastic member 250, the restoring deformation force of the elastic member 250 can make one end of the elastic member 250 embedded into another positioning slot 320, and the activating portion 310 can act on a contact of another functional circuit.

In addition, the inner wall of the positioning groove 320 may be an arc surface, specifically, the groove shape of the positioning groove 320 is a sphere-like structure, and one end of the elastic member 250, which is embedded in the positioning groove 320, may be configured to be matched with the groove shape of the positioning groove 320, so that when one end of the elastic member 250 is embedded in one positioning groove 320, one end of the elastic member 250 may slide along the inner wall of the positioning groove 320 by rotating the movable portion 300, and thus one end of the elastic member 250 may be separated from the positioning groove 320. Specifically, one end of the elastic member 250 may be provided with a ball 251.
