Description

Hall control components Technical Field

[0001] This utility model relates to the field of control components, specifically to a Hall effect control component. Background Technology

[0002] In traditional gas stoves, the flame intensity is typically adjusted via a mechanical main burner valve. After the gas stove is ignited, the flame intensity is adjusted by turning the valve handle to increase or decrease the gas flow. This adjustment method is stepless and requires manual observation of the flame intensity to adjust it to the appropriate level, making it inconvenient to operate. Moreover, with repeated operation over a long period, the seals between the valve core and the valve body are prone to wear, which can easily lead to gas leakage risks and pose a serious safety hazard.

[0003] A plug valve with an electrical signal control structure for adjusting the gas stove's flame position is disclosed. The valve includes a valve body and a knob. The valve body has a first and a second copper contact plate, while the knob has a third copper contact plate. Rotating the knob rotates the third copper contact plate, causing the first and second copper contact plates to conduct electricity. Different connections between the first and second copper contact plates generate different electrical signals, reflecting the gas stove's flame intensity. The valve body has a positioning sleeve containing a rotating shaft sleeve. The knob is connected to the rotating shaft sleeve, which contains a spring and a steel ball. The positioning sleeve has a groove in which the steel ball engages. When the knob is rotated, the steel ball slides across a protrusion between the two grooves, producing a slight damping sensation. This valve's position adjustment structure, featuring a positioning sleeve, rotating shaft sleeve, spring, and steel ball, allows users to clearly feel different gear positions and accurately pinpoint the desired setting. However, this plug valve has a complex structure. The third copper contact piece must contact the first and second copper contact pieces to conduct electricity and generate an electrical signal. After repeated use over a long period, the copper contact pieces will wear or deform, leading to poor contact and affecting the effective adjustment of the gear position. Moreover, the groove for mating with the steel ball is located on the inner circumferential wall of the positioning sleeve, which has the following drawbacks: 1) It requires high machining standards for the positioning sleeve; 2) During assembly, it is necessary to ensure that the steel ball on the rotating sleeve is precisely aligned with the inner groove of the positioning sleeve, requiring repeated adjustments and increasing assembly complexity; 3) It is difficult to repair or replace the positioning sleeve after the groove is worn, increasing maintenance costs. Summary of the Invention

[0004] The purpose of this invention is to provide a Hall effect control component that is simple in structure, convenient and effective in adjusting gears, and can eliminate the risk of gas leakage.

[0005] To achieve the above objectives, this utility model provides a Hall effect control component with multiple gear positions. The Hall effect control component includes a housing, a handle, a turntable, a rotating arm, and a first circuit board. An elastic positioning component is disposed within the housing. A rotating shaft is provided at one end of the handle, extending into the housing. The turntable is disposed within the housing, fitted onto the rotating shaft and rotating with it. The turntable has multiple through holes, into which the elastic extension end of the elastic positioning component can be inserted. The rotating arm is disposed within the housing, mounted on the rotating shaft and rotating with it. A magnet is disposed on the rotating arm. The first circuit board is disposed within the housing, positioned vertically above the rotating arm. Multiple Hall sensors are disposed on the first circuit board, arranged along the rotation path of the magnet, corresponding to the through holes and gear positions.

[0006] As can be seen from the above solution, by setting a magnet and multiple Hall sensors, each Hall sensor corresponds to a different gear position. When the magnet rotates with the handle, the Hall sensors sense different voltage signals through changes in the magnetic field, which is beneficial for gear adjustment. This avoids the wear of gas valve seals caused by mechanical adjustment in the prior art, thus eliminating the risk of gas leakage. Moreover, the Hall sensors and magnets do not need to be in direct contact, ensuring that the gear can still be effectively adjusted after repeated use over a long period of time, which helps to improve its service life. By setting the elastic telescopic end of the elastic positioning component to be embedded in the through hole, the user can clearly feel the gear position at different angles when rotating the handle. This does not hinder gear adjustment and can accurately position the rotation shaft gear to correspond to different firepower requirements. This utility model also has the advantages of simple structure, convenient assembly, and convenient operation.

[0007] A further design involves extending the elastic telescopic end in a direction parallel to the axis of rotation, with perforations set on the end face of the turntable, allowing the elastic telescopic end to slide from one perforation to another.

[0008] As can be seen from the above scheme, with the above settings, the elastic telescopic end is embedded into the perforation from the end face of the turntable, which not only helps to reduce the processing difficulty of the turntable, but also facilitates the assembly of the elastic positioning component and the turntable.

[0009] A further option is to have two elastic positioning components, which are respectively located on both sides of the rotating shaft; the turntable is provided with two sets of perforations, which are respectively located on both sides of the turntable, and the elastic positioning components move relative to each other between the perforations in the corresponding perforation groups.

[0010] As can be seen from the above scheme, the above settings not only ensure that the turntable is subjected to balanced force, but also increase the force on the turntable after it reaches the gear position, thus preventing the handle from accidentally touching and causing incorrect gear adjustment.

[0011] A further option is to have a mounting part inside the housing, the mounting part protruding from the inner wall of the housing, a rotating shaft passing through the center of the mounting part, and an elastic positioning component disposed on the mounting part.

[0012] As can be seen from the above scheme, the above settings not only allow sufficient installation space for the installation of the elastic positioning components, but also do not weaken the structural strength of the shell.

[0013] A further option is to provide an installation groove on the upper part of the installation section; the elastic positioning component is a separate component, which includes a steel ball and an elastic element. The steel ball is telescopically disposed in the installation groove, and the elastic element elastically abuts against the bottom of the installation groove between the steel ball and the groove; or, the elastic positioning component is a small component, which is a ball-head plunger, and the ball-head plunger is threadedly connected in the installation groove.

[0014] As can be seen from the above scheme, the elastic positioning components set separately can realize the elastic expansion and contraction of the steel ball; the elastic positioning components set in small parts can realize the elastic expansion and contraction of the steel ball while facilitating its installation, which helps to save assembly time and improve assembly efficiency.

[0015] A further option is to provide a receiving groove on the upper part of the installation section, in which the turntable is rotatably mounted.

[0016] A further option is to provide at least two first mounting posts inside the housing, with the two first mounting posts respectively located on both sides of the turntable. The top wall of the first mounting post is higher than the top wall of the rotating arm, and the first circuit board is fixedly connected to the two first mounting posts.

[0017] As can be seen from the above scheme, the above settings facilitate the fixed installation of the first circuit board.

[0018] A further embodiment is that the Hall control assembly also includes a start / stop switch and a second circuit board. The start / stop switch is located on one side of the handle, and the second circuit board is located inside the housing. One end of the start / stop switch extends into the housing and is electrically connected to the second circuit board.

[0019] As can be seen from the above scheme, the start / stop switch and the handle serve as backups for each other. When either switch fails, the user can continue to operate the gas stove through the other component, ensuring normal operation of the gas stove.

[0020] A further option is that the start / stop switch can move along its axis, and / or the start / stop switch can rotate along its axis.

[0021] As can be seen from the above scheme, through the above settings, the user can press the start / stop switch and / or rotate the start / stop switch to realize the gas stove ignition and firepower adjustment.

[0022] A further option is to provide a groove and at least two second mounting posts inside the housing. One end of the start / stop switch passes through the bottom of the groove, the second mounting posts are set inside the groove, and the second circuit board is fixed to the second mounting posts.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0028] Referring to Figures 1 to 4, the Hall control component provided in this embodiment has multiple settings, preferably 7 settings, which are arranged in order of firepower as follows: "0", "1", "2", "3", "4", "5" and "6". Among them, "0" is the off setting, and the other settings are all on settings.

[0029] The Hall effect control assembly includes a housing 1, a cover 2, a handle 3, a turntable 4, a rotating arm 5, and a first circuit board 6. The cover 2 is detachably connected to the housing 1 by screws (not shown in the figure). A cavity is formed between the housing 1 and the cover 2, and the turntable 4, the rotating arm 5, and the first circuit board 6 are all disposed within the cavity. A gear position indicator label (not shown in the figure) is provided on or around the housing 1, and an indicator part 31 that rotates with the handle 3 is provided on one side to indicate the current gear position.

[0030] The housing 1 contains a mounting portion 11 and two elastic positioning components 7. The mounting portion 11 protrudes from the inner wall of the housing 1. A rotating shaft 32 is provided at one end of the handle 3, extending into the housing 1 and passing through the center of the mounting portion 11. Both elastic positioning components 7 are provided on the mounting portion 11, and are respectively located on both sides of the rotating shaft 32. The elastic telescopic ends of the elastic positioning components 7 are telescopic, and the telescopic direction of the elastic telescopic ends is parallel to the axial direction of the rotating shaft 32.

[0031] The mounting section 11 is provided with a central hole 111, a receiving groove 112, and two mounting grooves 113. The central hole 111 and the receiving groove 112 are coaxially arranged. The two mounting grooves 113 are both located at the bottom of the receiving groove 112, and the two mounting grooves 113 are symmetrically arranged on both sides of the central hole 111. The mounting grooves 113 communicate with the receiving groove 112. The rotating shaft 32 is rotatably inserted into the central hole 111, and the elastic positioning component 7 is disposed in the corresponding mounting groove 113. The elastic telescopic end of the elastic positioning component 7 protrudes from the opening of the mounting groove 113.

[0032] The turntable 4 is mounted on the middle of the rotating shaft 32 and rotatably disposed within the receiving groove 112. A rectangular hole 41 is formed in the center of the turntable 4, which matches the rectangular section in the middle of the rotating shaft 32, allowing the turntable 4 to rotate with the rotating shaft 32. The turntable 4 has two sets of through holes, respectively located on both sides of the turntable 4. Each set of through holes contains seven through holes 42, each through hole 42 penetrating the turntable 4 from its end face. The elastic positioning component 7 moves relative to the through holes 42 within the corresponding through hole sets.

[0033] The turntable 4 is rotatably disposed within the receiving groove 112, and the elastic telescopic end of the elastic positioning component 7 is at least partially embedded in the through hole 42 to achieve positioning of the current gear. When the turntable 4 rotates, the elastic telescopic end can slide from one through hole 42 to another through hole 42 to achieve gear shifting.

[0034] A rotating arm 5 is disposed at the upper end of a rotating shaft 32 and can rotate with the rotating shaft 32. A magnet 51 is disposed at at least one end of the rotating arm 5. A mounting hole is provided at the end of the rotating arm 5, and the magnet 51 is fixedly disposed in the mounting hole. In this embodiment, the magnet 51 is frustum-shaped, and its axis is parallel to the rotating shaft 32, such that the south pole of the magnet 51 faces upward and the north pole faces downward, or the south pole faces downward and the north pole faces upward.

[0035] In Figure 4, the first circuit board 6 is disposed inside the housing 1 and above the rotating arm 5. Seven Hall sensors (not shown in the figure) are disposed on the first circuit board 6, arranged along the rotation path of the magnet 51. In the vertical direction, the projections of the multiple Hall sensors all fall on the rotation path of the magnet 51, allowing the magnet 51 to rotate directly below any of the Hall sensors. The Hall sensors are corresponding to the perforations 42 and the positions; specifically, the seven Hall sensors correspond to the seven positions of the Hall control handle 3, and the seven perforations 42 in the same group correspond to the seven positions of the Hall control handle 3.

[0036] When the rotating arm 5 drives the magnet 51 to rotate, causing the magnet 51 to rotate directly below one of the Hall sensors, the magnetic field strength sensed by the Hall sensor exceeds the trigger threshold, and the Hall sensor is triggered, indicating that the Hall control component has been adjusted to the corresponding level of the Hall sensor; the other Hall sensors are not directly above the magnet 51, the distance between the other Hall sensors and the magnet 51 is too far, or the magnetic field direction is not aligned, so the magnetic field strength sensed by the other Hall sensors is insufficient to trigger, and therefore they remain in an untriggered state.

[0037] In one embodiment, the elastic positioning component 7 is a separate component. The elastic positioning component 7 includes a steel ball and an elastic element. The steel ball is telescopically disposed within the mounting groove 113, and the elastic element elastically abuts against the bottom of the mounting groove 113, such that the steel ball partially protrudes from the opening of the mounting groove 113.

[0038] In another embodiment, the elastic positioning component 7 is a small component. In this embodiment, "small component" refers to a relatively independent, functionally defined, and structurally small part in the technical solution, typically featuring modularity and allowing for individual manufacturing, installation, or replacement. The elastic positioning component 7 is preferably a ball-head plunger, which includes a threaded hollow column, a steel ball, and a spring. The spring is disposed within the hollow column, and the steel ball is retractably mounted on the hollow column and positioned above the spring. Using a ball-head plunger facilitates assembly. In this case, to facilitate the installation of the ball-head plunger, the lower end of the mounting groove 113 must penetrate the mounting portion 11 and the housing 1 to allow the ball-head plunger to be installed from the outside of the housing 1.

[0039] Referring to Figures 2 and 4, to secure the first circuit board 6, at least two first mounting posts 12 are provided inside the housing 1. The two first mounting posts 12 are respectively located on both sides of the mounting portion 11. The top wall of the first mounting post 12 is higher than the top wall of the rotating arm 5. The first circuit board 6 is fixed to the two first mounting posts 12 by screws. In the vertical direction, the first circuit board 6 is slightly higher than the top walls of the magnet 51 and the rotating arm 5 to avoid obstructing the rotation of the magnet 51 and the rotating arm 5.

[0040] Referring to Figures 2 and 4, the Hall control component of this embodiment also includes a start / stop switch 8 and a second circuit board 9. The start / stop switch 8 is disposed on one side of the handle 3, and the second circuit board 9 is disposed inside the housing 1. One end of the start / stop switch 8 extends into the housing 1 and is electrically connected to the second circuit board 9.

[0041] The start / stop switch 8 can move along its axis, and / or, the start / stop switch 8 can rotate along its axis. When the start / stop switch 8 moves along its axis, the start / stop switch 8 is a push-button switch, which ignites the gas stove by pressing; when the start / stop switch 8 rotates along its axis, the start / stop switch 8 is a rotary switch, which ignites the gas stove and adjusts the flame by rotating counterclockwise.

[0042] The housing 1 is also provided with a groove 13 and at least two second mounting posts 14. One end of the start / stop switch 8 passes through the bottom of the groove 13 and extends into the groove 13. The second mounting posts 14 are set in the groove 13. The second circuit board 9 is fixed to the second mounting posts 14 by screws.

[0043] In summary, this invention, by incorporating a magnet and multiple Hall effect sensors, with each sensor corresponding to a different gear position, allows for gear adjustment by sensing different voltage signals through magnetic field changes as the magnet rotates with the handle. This facilitates gear adjustment and avoids the wear of gas valve seals caused by mechanical adjustment in existing technologies, thus eliminating the risk of gas leakage. Furthermore, the Hall effect sensors do not require direct contact with the magnet, ensuring effective gear adjustment even after repeated use, thereby extending the product's lifespan. The elastic telescopic end of the elastic positioning component can be embedded in the perforation, allowing the user to clearly feel the gear position at different angles when rotating the handle. This does not hinder gear adjustment but accurately positions the rotating shaft gear to meet different firepower requirements. This invention also boasts advantages such as simple structure, easy assembly, and convenient operation.

[0044] Finally, it should be emphasized that the above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
