Description

Technical Field

[0001] The present invention relates to the technical field of alarm devices, and more specifically to the technical field of a multi-directional adjustable anti-dry-burn alarm device. Background Art

[0002] The existing kitchen anti-dry burning alarm mainly monitors the temperature of the pot bottom through the temperature sensor or other technologies configured on the stove. When the temperature reaches a certain threshold, the alarm cuts off the gas source and extinguishes the flame, thereby preventing dry burning accidents. Some stoves do not have this function and can only achieve the warning effect through an external alarm. The external alarm of the existing technology detects whether a person has left the stove through a human infrared sensor, and detects whether the flame is extinguished through an infrared flame detector. The judgment based on the two sensors cannot meet the requirements of cooking scenarios such as slow-cooking soup and leaving the kitchen, and the accuracy is insufficient.

[0003] The external alarm of the prior art detects the smoke concentration in the air through a smoke detector and sends out an alarm signal when the smoke concentration reaches a certain threshold, which usually has the problem of false alarm or alarm lag.

[0004] The external alarms in the prior art are installed in a ceiling-mounted manner, and the detection area is a fixed area. There are requirements for the installation position and sensor orientation, and there are limitations in actual use, and some kitchens cannot meet the requirements. Some external alarms can rotate the alarm on a single axis through a built-in motor, but there are still restrictions on the installation position and sensor orientation in the kitchen. It needs to be installed facing the stove, and effective detection can only be performed after debugging. Users cannot change the installation position at will according to the home decoration situation, and there are limitations on use. At the same time, the built-in motor will increase the power consumption and external dimensions of the product, affecting the product's battery life and home decoration aesthetics. The cost of micro-stepping motors is also relatively high, and the monitoring angle of the alarm is only debugged during the initial installation. It is meaningless to increase the cost by using a stepping motor.

[0005] The detection accuracy of the external anti-dry-burning alarm device is poor, and it cannot detect oil stains. The alarm is affected by the home decoration environment and cannot be installed anywhere in the kitchen. The direction cannot be adjusted after installation, which results in the sensor being unable to accurately lock the stove and conduct effective monitoring. Reduce unnecessary circuit modules, reduce product costs, and miniaturize products while reducing power consumption and improving battery life. Summary of the invention

[0006] The purpose of the present invention is to solve the above technical problems and provide a multi-directional adjustable anti-dry burning alarm device.

[0007] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0008] The present invention provides a multi-directional adjustable anti-dry burning alarm device, comprising a housing, a sensor rotating module, a control mainboard electrically connected to the sensor rotating module, and an alarm device electrically connected to the control mainboard, wherein the sensor rotating module, the control mainboard and the alarm device are all arranged in the housing;

[0009] The sensor rotation module includes a base fixed in the shell, a Y-axis circular arc driving arm arranged in the base for rotation along the longitudinal direction, an X-axis circular arc driving arm arranged in the base for rotation along the transverse direction, a joint arm ball-connected in the base, and a detection assembly fixed at the end of the joint arm, the X-axis circular arc driving arm is located above the Y-axis circular arc driving arm and does not interfere with each other, a transverse guide groove is arranged on the upper edge of the X-axis circular arc driving arm in the transverse direction, and a longitudinal guide groove is arranged on the upper edge of the Y-axis circular arc driving arm in the longitudinal direction, and the joint arm passes through the longitudinal guide groove and the transverse guide groove in sequence and is fixedly connected to the detection assembly;

[0010] One end of the Y-axis circular arc driving arm is connected to a Y-axis rotation driving mechanism, and one end of the X-axis circular arc driving arm is connected to an X-axis rotation driving mechanism. The Y-axis rotation driving mechanism and the X-axis rotation driving mechanism are electric driving mechanisms or manual driving mechanisms.

[0011] Specifically, in order to achieve miniaturization of product size, it can be installed and used anywhere in the kitchen. The sensor rotation module can be adjusted in two-axis directions, reducing unnecessary circuit modules, reducing costs and power consumption, and improving product endurance.

[0012] The X and Y axis have a wide bidirectional adjustment angle range, which is suitable for installation in various kitchen structures. The structural parts can further reduce the overall size of the module by changing the material according to the actual application situation, so as to realize the miniaturization of the product. The solution can be adjusted manually to reduce unnecessary circuit modules, reduce the power consumption of the alarm device, and improve the battery life of the alarm device; the application cost can be greatly reduced by not using micro-stepping motors. Furthermore, if necessary, stepper motors can be installed at the X-axis knob and the Y-axis knob to realize electronic control, such as Figure 3 As shown (this solution is not limited to manual control).

[0013] The IP protection of the anti-dry burning alarm device reaches IP66, which can prevent the intrusion of oil smoke and oil pollution and affect the detection accuracy of the sensor.

[0014] In one embodiment, the X-axis arc driving arm and the Y-axis arc driving arm have the same structure, both including an upwardly protruding arc driving arm and two rotating shafts arranged at both ends of the arc driving arm. The base is a groove-shaped structure opening upward, and each rotating shaft is installed on the base through bearings.

[0015] Specifically, the base is provided with a matching ball sleeve according to the joint ball, the bottom of the joint arm is fixedly connected to the joint ball, and further, corresponding shaft holes are provided on the shell according to the X-axis rotation drive mechanism and the Y-axis rotation drive mechanism, and the drives in the two directions are kept at the same rotation center ( Figure 3 ).

[0016] In one embodiment, the shell includes a magnetic mounting base plate, a magnet lower cover that cooperates with the magnetic mounting base plate, and an upper cover that cooperates with the lower cover. A circle of sealing grooves is provided on the edge of the lower cover, an O-ring is provided in the sealing groove, and a stop sealing line that is in compression contact with the O-ring is provided on the edge of the upper cover. The upper cover and the lower cover are closed by ultrasonic welding or screw fastening.

[0017] Specifically, a sealing groove is provided in the lower cover, and an O-ring is installed in the sealing groove. The O-ring is made of soft material such as nitrile rubber or silicone. The upper cover and the lower cover are closed by ultrasonic welding or screw fastening. The stopper sealing line provided in the upper cover squeezes the O-ring. The O-ring is fully deformed and completely fills all gaps that may cause liquid or gas leakage, forming a reliable sealing barrier to meet the shell protection requirements ( Figure 2 ).

[0018] In one embodiment, the detection assembly integrates an infrared imaging sensor and a laser diode.

[0019] Specifically, the detection component integrates an infrared imaging sensor and a laser diode (not limited to the above two types), a joint arm is set at the root of the detection component, and a joint ball is set at the tail of the joint arm ( Figure 3 ). It can be installed on the walls or ceiling around the kitchen. Through the two knobs in the X and Y directions of the alarm, the sensor module can be rotated in two axes, and the specific detection position can be determined by observing the laser mark.

[0020] In one embodiment, the manual drive mechanism includes an X-axis knob and a Y-axis knob, and the lower cover is provided with an X-axis knob hole and a Y-axis knob hole. O-rings are provided on the X-axis knob and the Y-axis knob. After the X-axis knob and the Y-axis knob are inserted into the X-axis knob hole and the Y-axis knob hole, the corresponding O-rings are squeezed and sealed with the side wall of the lower cover, and the X-axis knob is fixed on the X-axis rotation drive mechanism, and the Y-axis knob is fixed on the Y-axis rotation drive mechanism.

[0021] Specifically, the X-axis rotary drive mechanism has an X-axis knob (not limited to such morphological features) on its exterior surface, which can be rotated by tools or hands. The Y-axis rotary drive mechanism is the same as above, and the outer diameter of the Y-axis circular drive arm is smaller than the inner diameter of the X-axis circular drive arm. Figure 3 shown.

[0022] During installation, an O-ring is set on the X-axis knob and Y-axis knob of the sensor rotation module. After the X-axis knob and Y-axis knob are inserted into the X-axis knob hole and Y-axis knob hole of the lower cover, the O-ring is squeezed against the side wall of the lower cover to achieve the protection purpose (such as Figure 2 and Figure 3 ).

[0023] How it works

[0024] The X-axis rotation drive mechanism and the Y-axis rotation drive mechanism are installed between the sensor and the joint ball of the detection component. The joint ball is inserted into the ball sleeve of the base. The ball sleeve allows the detection component to only move the center of the ball and cannot be separated from the base. The X-axis rotation drive mechanism and the Y-axis rotation drive mechanism are in a vertical state, and their rotation axes are embedded in the corresponding shaft holes of the base. When the X-axis knob is driven, the X-axis circular arc drive arm causes the joint arm to rotate along the X-axis, and the corresponding Y-axis circular arc drive arm is hollowed out in the middle, and the axial rotation of the X-axis does not affect each other with the Y-axis rotation drive mechanism. Similarly, when the Y-axis knob is driven, the Y-axis circular arc drive arm causes the joint arm to rotate along the Y-axis, and the corresponding X-axis circular arc drive arm is hollowed out in the middle, and the axial rotation of the Y-axis does not affect each other with the X-axis rotation drive mechanism. ( Figure 3 ).

[0025] In one embodiment, it also includes a battery that supplies power to the sensor rotation module, the control main board, and the alarm device. A charging port connected to the battery is provided on the lower cover or the upper cover, and a protective cover installed at the charging port by interference fit is provided at the charging port.

[0026] Specifically, a protective cover is provided at the charging port of the upper cover. The protective cover is made of TPU soft material and has an interference fit with the charging port of the upper cover. The charging port of the upper cover squeezes the protective cover to form a sealing surface to achieve the purpose of protection. Figure 2 The alarm display uses a digital tube and has a built-in rechargeable battery, which reduces unnecessary circuit modules, reduces costs and power consumption, and improves battery life.

[0027] In one embodiment, a sound outlet is provided on the upper cover at a position corresponding to the alarm device, a sound cavity is provided inside the sound outlet, a second sealing ring is installed in the sound cavity, and the alarm device is embedded in the sound cavity and contacts the second sealing ring by extrusion.

[0028] Specifically, a sound cavity is set inside the sound outlet of the upper cover, and a second sealing ring is installed in the sound cavity. The second sealing ring is made of soft material (such as nitrile rubber or silicone), and the buzzer is embedded in the sound cavity to squeeze the sealing ring to achieve the protection purpose (such as Figure 1 , Figure 2 ).

[0029] In one embodiment, a sensor lens is disposed on the upper cover facing the sensor rotation module, and the sensor lens and the upper cover are sealed by adhesive bonding, and the bonding surface between the sensor lens and the upper cover forms a continuous and airtight adhesive layer.

[0030] Specifically, the sensor lens on the upper cover is sealed with the upper cover adhesive, and the sticky substance fills the unevenness of the bonding surface at the microscopic level, forming a continuous and airtight adhesive layer between the two bonding surfaces, like a barrier, blocking the passage of moisture and achieving the purpose of protection (such as Figure 1 ).

[0031] In one embodiment, a magnetic mounting base plate has a nail-free adhesive or double-sided adhesive tape at the bottom thereof for sticking to a wall or ceiling.

[0032] Specifically, the installation method of the magnetic mounting base is as follows: the mounting base is attached to the wall or ceiling by nail-free glue or double-sided tape, and the alarm device is embedded with a magnet or iron metal sheet and magnetically mounted with the mounting base. The mounting base is not limited to an embedded magnet or iron metal sheet or an independent iron metal sheet (such as Figure 1 ).

[0033] In one embodiment, the alarm device is a buzzer.

[0034] The beneficial effects of the present invention are as follows:

[0035] 1. In order to achieve miniaturization of product size, the present invention can be installed and used at any position in the kitchen. The bidirectional adjustment angle range of the X and Y axes is large, which is suitable for installation in various kitchen structures. The structural parts can further compress the overall size of the module by changing the material according to the actual application situation, so as to achieve miniaturization of product application. The application cost can be greatly reduced by not using a micro-stepping motor. Furthermore, if necessary, a stepping motor can be set at the X-axis knob and the Y-axis knob to achieve electronic control.

[0036] 2. The protection level of the alarm reaches IP66, which solves the problem of detection accuracy or inability to detect caused by oil contamination on the sensor of the alarm device;

[0037] 3. By manually adjusting the sensor, unnecessary circuit modules can be reduced, costs and power consumption can be reduced, and product endurance can be improved. BRIEF DESCRIPTION OF THE DRAWINGS
