Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and in particular to a gas intake pipeline system, a gas stove, and a gas intake control method. Background Technology

[0002] Currently, gas stoves have become an essential kitchen appliance for an increasing number of families, bringing convenience to users' lives. However, because gas is colorless and odorless, users are completely unaware of leaks, which can easily lead to safety accidents.

[0003] One of the causes of gas leaks is the presence of leaks in gas pipelines. However, existing gas pipelines are usually unable to automatically detect leaks. If users fail to detect leaks in time, the concentration of leaked gas may cause personal and property safety issues once it reaches a certain level.

[0004] Therefore, there is an urgent need for a gas intake pipeline system, a gas stove, and a gas intake control method to solve the above problems. Summary of the Invention

[0005] Based on the above problems, the purpose of this invention is to provide a gas intake pipeline system, a gas stove, and a gas intake control method, which can shut off the gas in a timely manner to prevent gas leaks and safety accidents.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] In a first aspect, a gas intake pipeline system is provided, comprising:

[0008] Gas supply pipe and gas inlet pipe;

[0009] A gas control device includes a housing and a pressure detection component and a blocking component disposed within the housing. The housing has an inlet and an outlet. The inlet is used to connect to the gas supply pipe, and the outlet is used to connect to the gas inlet pipe. The pressure detection component is used to detect the gas pressure inside the housing, and the blocking component can selectively open or block the outlet according to the gas pressure detected by the pressure detection component.

[0010] As a preferred embodiment of the gas intake pipeline system of the present invention, the gas control device further includes a control module and a drive component. The drive component and the pressure detection component are both communicatively connected to the control module. The output end of the drive component is connected to the sealing component. The control module can control the opening and closing of the drive component according to the gas pressure detected by the pressure detection component, so that the drive component drives the sealing component to open or block the gas outlet.

[0011] As a preferred embodiment of the gas intake pipeline system of the present invention, the pressure detection component includes a connected elastic diaphragm drum and a conductive rod. A conductive contact plate electrically connected to the control module is provided inside the housing. The elastic diaphragm drum can expand or contract when the gas pressure inside the housing changes, and drive the conductive rod to move along a preset direction to contact or separate from the conductive contact plate. When the conductive rod contacts the conductive contact plate, the control module controls the driving component to drive the sealing component to open the gas outlet. When the conductive rod separates from the conductive contact plate, the control module controls the driving component to drive the sealing component to block the gas outlet.

[0012] As a preferred embodiment of the gas intake pipeline system of the present invention, a partition structure is provided inside the housing, the partition structure surrounds an installation cavity inside the housing, the conductive contact is located inside the installation cavity, the elastic diaphragm is located outside the installation cavity, and one end of the conductive rod extends into the installation cavity and is movably inserted through the partition structure.

[0013] As a preferred embodiment of the gas intake pipeline system of the present invention, the partition structure has a guide hole, the conductive rod is movably inserted through the guide hole, and a contact rod is provided at one end of the conductive rod located in the mounting cavity. The contact rod is set at an angle to the conductive rod and is located below the conductive contact piece.

[0014] As a preferred embodiment of the gas intake pipeline system of the present invention, the sealing component includes a baffle and a sealing element, the sealing element being disposed on the side of the baffle facing the gas outlet, and the sealing element being able to seal and block the gas outlet.

[0015] As a preferred embodiment of the gas intake pipeline system of the present invention, the baffle is rotatably connected to the inner wall of the housing via a rotating shaft, and the output end of the drive member is connected to the baffle and can drive the baffle to rotate around the rotating shaft.

[0016] As a preferred embodiment of the gas intake pipeline system of the present invention, the gas intake pipeline system further includes a display module and an alarm module. The gas pressure detected by the pressure detection component is displayed through the display module. When the gas pressure detected by the pressure detection component is less than a preset value, the alarm module can issue an alarm and display it on the display module.

[0017] Secondly, a gas stove is provided, including a burner and a gas intake pipeline system as described above, wherein the gas intake pipeline is connected to the burner via a stopcock valve.

[0018] Thirdly, a gas intake control method is provided, applied to the gas intake pipeline system described above, comprising the following steps:

[0019] The pressure detection component detects the gas pressure inside the housing in real time.

[0020] When the gas pressure detected by the pressure detection component is greater than or equal to a preset value, the sealing component is controlled to open the gas outlet to connect the gas supply pipe and the gas inlet pipe.

[0021] When the gas pressure detected by the pressure detection component is less than the preset value, the sealing component is controlled to seal the gas outlet to disconnect the gas supply pipe and the gas inlet pipe.

[0022] The beneficial effects of this invention are as follows:

[0023] The gas intake pipeline system, gas stove, and gas intake control method provided by this invention allow gas to be supplied to the gas intake pipe via the gas supply pipe during the use of the gas stove. During this process, gas enters through the intake port and fills the housing of the gas control device. If the gas intake pipe is properly sealed, the gas pressure inside the housing meets a preset value. The gas pressure detected by the pressure detection component is greater than or equal to the preset value, and the sealing component opens the outlet of the housing, allowing gas to be smoothly supplied from the gas supply pipe to the gas intake pipe, and then distributed to the burner for combustion via a stopcock valve. If there is a leak in the gas intake pipe, the gas pressure inside the housing will inevitably be lower than when the gas intake pipe is sealed. The gas pressure detected by the pressure detection component will be less than the preset value. In this case, the sealing component seals the outlet of the housing, preventing gas from continuing to be supplied to the gas intake pipe and avoiding gas leakage. In other words, this gas intake pipeline system can promptly shut off the gas supply in the event of a leak in the gas intake pipe, preventing continuous gas leakage that could lead to a safety accident and improving the safety of the gas stove.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0041] like Figures 1 to 5 As shown, this embodiment provides a gas intake pipeline system for use in gas stoves. It can promptly shut off the gas supply in case of gas pipeline leakage, preventing safety accidents caused by gas leaks. The gas intake pipeline system includes a gas supply pipe, a gas intake pipe 1, and a gas control device 2.

[0042] Among them, see Figure 1 and Figure 2 The gas control device 2 includes a housing 21 and a pressure detection component 22 and a sealing component 23 disposed within the housing 21. The housing 21 has an inlet 211 and an outlet 212. The inlet 211 is used to connect to the gas supply pipe, and the outlet 212 is used to connect to the gas inlet pipe 1. The pressure detection component 22 is used to detect the gas pressure inside the housing 21, and the sealing component 23 can selectively open or block the outlet 212 according to the gas pressure detected by the pressure detection component 22.

[0043] like Figure 1 and Figure 2 As shown, one end of the gas inlet pipe 1 is connected to the gas outlet 212 of the housing 21 of the gas control device 2, and the other end of the gas inlet pipe 1 is connected to a stopcock valve 3. The gas supplied through the gas inlet pipe 1 is distributed to the burner through the stopcock valve 3 for ignition and cooking. The firepower of the burner can be adjusted through the stopcock valve 3.

[0044] In this embodiment, the gas intake pipeline system delivers gas to the gas intake pipe 1 via the gas supply pipe during the use of the gas stove. During this process, gas enters through the intake port 211 and fills the housing 21 of the gas control device 2. If the gas intake pipe 1 is properly sealed, the gas pressure inside the housing 21 meets the preset value requirement. The gas pressure detected by the pressure detection component 22 is greater than or equal to the preset value. The sealing component 23 opens the outlet 212 of the housing 21, allowing gas to be smoothly delivered from the gas supply pipe to the gas intake pipe 1, and then distributed to the burner for combustion via the stopcock valve 3. If there is a leak in the gas intake pipe 1, the gas pressure inside the housing 21 will inevitably be lower than when the gas intake pipe 1 is sealed. The gas pressure detected by the pressure detection component 22 will be less than the preset value. At this time, the sealing component 23 is controlled to seal the outlet 212 of the housing 21 to prevent gas from continuing to be delivered to the gas intake pipe 1 and to avoid gas leakage. That is, the gas inlet pipeline system can shut off the gas supply in time if there is a leak in the gas inlet pipe 1, so as to avoid the safety accident caused by continuous gas leakage and improve the safety of gas stove use.

[0045] Optionally, see Figure 2 The gas control device 2 also includes a control module and a drive component 24. Both the drive component 24 and the pressure detection component 22 are communicatively connected to the control module. The output end of the drive component 24 is connected to the sealing component 23. The control module can control the opening and closing of the drive component 24 according to the gas pressure detected by the pressure detection component 22, so that the drive component 24 drives the sealing component 23 to open or block the gas outlet 212. Specifically, when the gas pressure detected by the pressure detection component 22 meets the preset value, it indicates that there is no gas leak. After receiving the corresponding instruction, the control module controls the drive component 24 to start, thereby driving the sealing component 23 to open the gas outlet 212, allowing gas to flow smoothly. If the gas pressure detected by the pressure detection component 22 is less than the preset value, it indicates that there is a leak in the gas inlet pipe 1. After receiving the instruction, the control module controls the drive component 24 to drive the sealing component 23 to block the gas outlet 212, thereby shutting off the gas supply and preventing further gas leakage. The control module and drive unit 24 work together to intelligently control the sealing component 23 to open and seal the gas outlet 212 according to the gas pressure, so as to shut off the gas in time and avoid the gas leakage from causing a safety accident.

[0046] Optionally, see Figure 3 and Figure 5The pressure detection component 22 includes a connected elastic diaphragm drum 221 and a conductive rod 222. A conductive contact 213 electrically connected to the control module is provided inside the housing 21. The elastic diaphragm drum 221 can expand or contract when the gas pressure inside the housing 21 changes, and drive the conductive rod 222 to move in a preset direction to contact or separate from the conductive contact 213. When the conductive rod 222 contacts the conductive contact 213, the control module controls the drive component 24 to drive the sealing component 23 to open the gas outlet 212. When the conductive rod 222 separates from the conductive contact 213, the control module controls the drive component 24 to drive the sealing component 23 to block the gas outlet 212.

[0047] In this embodiment, the preset direction is Figure 3 For the vertical direction, please refer to... Figure 3 and Figure 4 With the gas inlet pipe 1 properly sealed, the gas pressure inside the housing 21 is high enough to cause the elastic diaphragm drum 221 to contract inward under pressure. Figure 4 The arrow at the top center points in the contraction direction, causing the conductive rod 222 to move upwards and contact the conductive contact 213. After the conductive rod 222 contacts the conductive contact 213, the control module receives a corresponding current signal, thereby controlling the drive component 24 to start, driving the sealing assembly 23 to open the gas outlet 212, allowing the gas to flow along... Figure 4 The arrow in the lower middle direction indicates flow.

[0048] If there is a leak in the gas inlet pipe 1, the gas pressure inside the housing 21 will be lower than the gas pressure in the sealed state. At this time, the elastic diaphragm drum 221 will expand outward, thereby driving the conductive rod 222 to move downward, and the conductive rod 222 will disengage from the conductive contact 213 (e.g., Figure 5 As shown in the figure, at this time the current signal received by the control module changes, thereby controlling the drive component 24 to drive the sealing component 23 to seal the gas outlet 212 and cut off the gas supply.

[0049] Before using the gas stove, users can adjust the gas pressure in the gas inlet pipe 1 according to the instruction manual to ensure that the gas pressure in the sealed state is sufficient to cause the elastic diaphragm drum 221 to contract and drive the conductive rod 222 to make good contact with the conductive contact piece 213.

[0050] For example, the elastic diaphragm drum 221 is made of rubber material and is ellipsoidal in shape. This design ensures that the elastic diaphragm drum 221 has sufficient contact area with the gas inside the housing 21, which is more conducive to the elastic diaphragm drum 221 sensing changes in gas pressure and generating corresponding elastic deformation.

[0051] Furthermore, the control module is a chip with a preset control program. When the conductive contact 213 and the conductive rod 222 form a circuit, the chip can receive a current signal and then control the driving component 24 to drive the sealing component 23 to open the vent 212 according to the preset control program. When the conductive rod 222 separates from the conductive contact 213, the current signal received by the chip changes, and the driving component 24 is controlled to drive the sealing component 23 to block the vent 212 according to the preset control program.

[0052] In another alternative embodiment, the pressure detection component 22 may also be a pressure sensor or the like, which feeds back a corresponding control signal to the control module based on the gas pressure detected by the pressure sensor inside the housing 21, so that the sealing component 23 seals or opens the gas outlet 212.

[0053] Optionally, see Figure 3 and Figure 5 A partition structure 214 is provided inside the housing 21, forming an installation cavity 215. A conductive contact 213 is located inside the installation cavity 215, and an elastic diaphragm drum 221 is located outside the installation cavity 215. One end of a conductive rod 222 extends into the installation cavity 215 and is movably inserted through the partition structure 214. The partition structure 214 isolates the conductive contact 213 and the conductive rod 222 from the outside, preventing the gas inside the housing 21 from hindering the contact and separation of the conductive rod 222 and the conductive contact 213. This ensures that the contact and separation of the conductive rod 222 and the conductive contact 213 are only affected by the deformation of the elastic diaphragm drum 221, guaranteeing the accuracy of pressure detection by the pressure detection assembly 22.

[0054] In this embodiment, the lower space inside the housing 21 is used to connect the air inlet 211 and the air outlet 212, and the partition structure 214 is located in the upper space inside the housing 21. This arrangement can prevent the partition structure 214 and the pressure detection component 22 from obstructing the flow of gas, while allowing the elastic diaphragm drum 221 to sense the gas pressure inside the housing 21 in real time, thus ensuring the accuracy of gas pressure detection.

[0055] Furthermore, the partition structure 214 has a guide hole 2141, through which the conductive rod 222 movably passes. One end of the conductive rod 222, located within the mounting cavity 215, is equipped with a contact rod 2221. The contact rod 2221 is angled to the conductive rod 222 and positioned below the conductive contact piece 213. The guide hole 2141 guides the movement of the conductive rod 222, ensuring it can only move in a predetermined direction, thus guaranteeing that the conductive rod 222 can only contact and separate from the conductive contact piece 213 under the action of the elastic diaphragm drum 221. The contact rod 2221 ensures good conductivity after contact between the conductive rod 222 and the conductive contact piece 213, while also preventing the conductive rod 222 from detaching from the guide hole 2141, thus acting as a limiting element.

[0056] In this embodiment, the guide hole 2141 extends vertically so that the conductive rod 222 can only move vertically. The contact rod 2221 is arranged perpendicularly to the conductive rod 222 and parallel to the conductive contact piece 213 so that the contact rod 2221 can stably fit with the conductive contact piece 213.

[0057] See Figure 3 and Figure 5 The partition structure 214 is in the shape of a rectangular box and is connected to the inner wall of the housing 21 to ensure the relative airtightness of the mounting cavity 215, so that the contact and separation of the conductive rod 222 and the conductive contact piece 213 are not affected by the gas pressure.

[0058] Optionally, the gas intake pipeline system also includes a display module and an alarm module. The gas pressure detected by the pressure detection component 22 is displayed on the display module. When the gas pressure detected by the pressure detection component 22 is lower than a preset value, the alarm module can issue an alarm and display it on the display module. Real-time display of gas pressure via the display module allows users to easily check the current gas pressure in the gas intake pipe 1. The alarm module ensures timely alerts to users in case of gas leakage, enabling them to take appropriate measures to avoid personal injury or property damage caused by gas leaks.

[0059] For example, the display module can be a display screen installed on the gas stove, or it can be a user app for the gas stove. The gas pressure detected by the pressure detection component 22 can be fed back to the user app for display. The alarm module can be in the form of an alarm indicator light, a buzzer, or a voice prompt, etc. The alarm module can also send an alarm signal to the user app for alarm notification.

[0060] Optionally, see Figure 3 The sealing assembly 23 includes a baffle 231 and a seal 232. The seal 232 is disposed on the side of the baffle 231 facing the gas outlet 212, and the seal 232 can seal and block the gas outlet 212. The seal 232 can tightly seal the gas outlet 212, preventing the gas supply from continuing and leaking. For example, the baffle 231 is made of metal material and has a certain supporting strength, while the seal 232 is made of rubber or silicone material, providing a good sealing effect.

[0061] Optionally, see Figure 3 The baffle 231 is rotatably connected to the inner wall of the housing 21 via a rotating shaft 233. The output end of the drive unit 24 is connected to the baffle 231 and can drive the baffle 231 to rotate around the rotating shaft 233. The baffle 231 is driven to open or block the air outlet 212 by rotation, which is easy to implement and has a simple structure.

[0062] For example, the driving component 24 is a solenoid valve, which is connected to a push rod 241. The push rod 241 is connected to a baffle 231. When the conductive rod 222 contacts the conductive contact 213, the solenoid valve is energized, and the push rod 241 extends to push the baffle 231 to rotate outward around the shaft 233, opening it to a certain angle and opening the air outlet 212. When the conductive rod 222 separates from the conductive contact 213, the solenoid valve is de-energized, and the push rod 241 retracts to drive the baffle 231 to rotate inward around the shaft 233, closing it until the baffle 231 blocks the air outlet 212.

[0063] In other embodiments, the drive element 24 can be a linear drive mechanism such as a linear motor, cylinder, or hydraulic cylinder, or the drive element 24 can be a rotary drive mechanism (such as a stepper motor). The output end of the rotary drive mechanism is connected to the rotating shaft 233 to directly drive the rotating shaft 233 to rotate, thereby causing the baffle 231 to rotate open or rotate closed.

[0064] This embodiment also provides a gas stove, including a burner and a gas intake pipeline system as described above. The gas intake pipe 1 is connected to the burner via a stopcock valve 3. The stopcock valve 3 distributes gas to the burner for ignition and cooking. The burner's power can be adjusted via the stopcock valve 3. Gas stoves using this gas intake pipeline system can promptly shut off the gas supply in case of a leak in the gas intake pipe 1, preventing continuous gas leakage and potential safety accidents, thus improving the safety of the gas stove.

[0065] This embodiment also provides a gas intake control method, applied to the gas intake pipeline system described above, comprising the following steps:

[0066] S1. Pressure detection component 22 detects the gas pressure inside housing 21 in real time;

[0067] S2. When the gas pressure detected by the pressure detection component 22 is greater than or equal to the preset value, the control blockage component 23 opens the gas outlet 212 to connect the gas supply pipe and the gas inlet pipe 1.

[0068] S3. When the gas pressure detected by the pressure detection component 22 is less than the preset value, the control blockage component 23 blocks the gas outlet 212 to disconnect the gas supply pipe and the gas inlet pipe 1.

[0069] In step S1, the pressure detection component 22 senses the gas pressure by deforming the elastic diaphragm drum 221. In steps S2 and S3, the drive component 24, taking a solenoid valve as an example, uses the push rod 241 of the solenoid valve to drive the sealing component 23 to open and seal the gas outlet 212.

[0070] Specifically, when the gas pressure reaches the preset value, the elastic diaphragm drum 221 contracts and deforms, causing the conductive rod 222 to move upward and contact the conductive contact 213 to form a circuit. At this time, the solenoid valve is energized, the push rod 241 extends, and pushes the baffle 231 to rotate outward and open, so that the gas outlet 212 is open. If there is a leak in the gas inlet pipe 1, the gas pressure in the housing 21 will decrease. If the gas pressure is less than the preset value, the elastic diaphragm drum 221 expands and deforms, causing the conductive rod 222 to move downward and separate from the conductive contact 213. At this time, the solenoid valve is de-energized, the push rod 241 retracts, and pulls the baffle 231 to rotate inward and close. The baffle 231 and the seal 232 cooperate to seal and block the gas outlet 212.

[0071] By controlling the gas intake pipeline system using this gas intake control method, the gas pressure can be detected in real time. If there is a leak in the gas intake pipe 1, the gas supply can be shut off in time, and an alarm module can be used to send an alarm reminder to the user to avoid continuous gas leakage and safety accidents, thereby improving the safety of gas stove use.

[0072] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
