Description

Technical Field

[0001] This invention relates to the field of gas stove technology, and in particular to a multi-directional pipeline regulating device and a gas stove. Background Technology

[0002] Existing gas stoves designed for batch cooking have two burners, each with its own gas flow control. This means that when the same food needs to be cooked on both burners simultaneously, the user must adjust the gas flow of both burners at the same time. However, the order in which the burners are turned on is different, and it is difficult to keep the gas flow control consistent, resulting in differences in the taste of the same food served. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-directional pipeline adjustment device and a gas stove to alleviate the technical problem of poor cooking consistency in existing batch-cooking gas stoves.

[0004] In a first aspect, the present invention provides a multi-directional pipeline adjustment device, comprising: An air intake base is provided with a main gas inlet and n gas outlets, and the main gas inlet and each of the gas outlets are connected by a channel; n is an integer greater than or equal to 2. n valve bodies, each valve body being movably connected to the air intake base, each valve body corresponding one-to-one with the channel, and each valve body being at least partially located within the channel for adjusting the flow rate of the channel; The linkage component is equipped with n linkage locking mechanisms, each corresponding to a valve body. The linkage locking mechanism can switch between a locked state and an unlocked state. When in the locked state, the linkage locking mechanism connects the linkage component to the valve body, so that the linkage component drives the valve body to move, thereby changing the flow rate of the channel. A main drive mechanism is connected to the linkage component and is used to drive the linkage component to move, thereby causing all valve bodies connected to the linkage component to move, so as to change the flow rate of the multiple channels simultaneously and equally.

[0005] Furthermore, the valve body includes a gear shaft, a blade, a spring, and a push rod. The gear shaft is rotatably connected to the air intake base, and the blade is connected to the gear shaft and located within the channel. By changing the rotation angle of the blade, the flow rate of the channel can be changed. A portion of the gear shaft is located outside the air intake base, and the gear shaft located outside the air intake base is provided with an external thread. The push rod is provided with a threaded hole, and the threaded hole is threadedly connected to the external thread. The push rod is provided with a first snap-fit ​​portion. The linkage locking mechanism includes a movable locking block, on which a second engaging part is provided. After the second engaging part engages with the first engaging part, it prevents the push rod from rotating around the gear shaft and has the same motion state as the locking block in the axial direction of the gear shaft. The spring is sleeved on the gear shaft and located between the push rod and the air intake base so that the push rod abuts against the locking block.

[0006] Furthermore, the linkage locking mechanism includes a slider, and the slider is provided with n slide rails, each slide rail corresponding to a locking block, and the locking block is slidably connected within the slide rails; The locking block includes an electromagnet; a magnetic element is provided in the slide rail, which attracts or repels the locking block after the electromagnet is energized, so that the locking block moves between a first position and a second position in the slide rail. When the locking block is in the first position, the second locking part is separated from the first locking part; when the locking block is in the second position, the second locking part is connected to the first locking part.

[0007] Furthermore, the main drive mechanism is connected to the slider and is used to drive the slider to move axially along the gear shaft.

[0008] Furthermore, the main drive mechanism includes a motor, a lead screw base, and a lead screw. The motor and the lead screw base are respectively connected to both ends of the lead screw, and the motor drives the lead screw to rotate. The lead screw is threadedly connected to the slider, and the slider is slidably connected to the lead screw base along a straight line.

[0009] Furthermore, the air intake base is provided with two sealed bearings located at both ends of the blade, and the sealed bearings are connected to the gear shaft.

[0010] Furthermore, the inner wall of the channel is provided with a first elastic sealing structure and a second elastic sealing structure facing each other. When the blade is in a position where the flow rate of the channel is 0, the two opposite edges of the blade abut against the first elastic sealing structure and the second elastic sealing structure respectively, so as to reduce the gap between the blade and the inner wall of the channel.

[0011] Furthermore, mounting grooves are provided on both opposite inner walls of the channel; Both the first and second elastic sealing structures include an elastic slider and a spring sheet connected to each other. The spring sheet is disposed in the mounting groove and located between the bottom of the mounting groove and the elastic slider, so that the elastic slider floats at the opening of the mounting groove.

[0012] Furthermore, n=2, meaning the two gas outlets are symmetrically arranged relative to the main gas inlet.

[0013] Secondly, the present invention provides a gas stove including the aforementioned multi-directional pipeline adjustment device.

[0014] This invention has at least the following advantages or beneficial effects: The multi-directional pipeline adjustment device provided by the present invention includes: an air inlet base, on which a main gas inlet and n gas outlets are provided, wherein the main gas inlet and each of the gas outlets are connected by a channel; n is an integer greater than or equal to 2; n valve bodies, which are movably connected to the air inlet base, each valve body corresponding to one of the channels, and each valve body being at least partially located within the channel for adjusting the flow rate of the channel; a linkage component, on which n linkage locking mechanisms are provided, each linkage locking mechanism corresponding to one of the valve bodies; the linkage locking mechanism is capable of switching between a locked state and an unlocked state, and when in the locked state, the linkage locking mechanism connects the linkage component to the valve body, so that the linkage component drives the valve body to move, thereby changing the flow rate of the channel; and a main drive mechanism, which is connected to the linkage component and is used to drive the linkage component to move, thereby driving all valve bodies connected to the linkage component to move, thereby simultaneously and equally changing the flow rate of the multiple channels.

[0015] This multi-directional pipeline regulating device can achieve either a single-output gas mode or a simultaneous multi-output gas mode. Initially, all interlocking mechanisms are unlocked. When single-output mode is required, the interlocking mechanism corresponding to the selected gas outlet is locked. At this time, the interlocking component connects to the corresponding valve body, causing the interlocking component to move the valve body, thereby changing the flow rate of that gas outlet. When multiple gas outlets are needed, the interlocking mechanisms corresponding to multiple gas outlets are locked. The main drive mechanism then drives multiple valve bodies to move together via the interlocking components, allowing each burner to output gas simultaneously and in equal amounts, achieving simultaneous cooking across multiple burners.

[0016] Secondly, the gas stove provided by the present invention includes the aforementioned multi-directional pipeline adjustment device. Because the gas stove provided by the present invention incorporates the aforementioned multi-directional pipeline adjustment device, it also possesses the advantages of the multi-directional pipeline adjustment device.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

[0025] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] like Figures 1-8 As shown, the multi-directional pipeline regulating device provided by the present invention can be installed on a gas stove for supplying gas.

[0027] like Figure 4 and Figure 6As shown, the system specifically includes: an air inlet base 1, which is equipped with a main gas inlet and n gas outlets 22. The main gas inlet is connected to a gas source. Each gas outlet 22 is connected to a burner head via a connector 15. n is an integer greater than or equal to 2; in this embodiment, n=2. The main gas inlet and each gas outlet 22 are connected via a channel 21; n valve bodies are movably connected to the air inlet base 1, each valve body corresponding to a channel 21. Each valve body is at least partially located within a channel 21 and is used to adjust the flow rate of the channel 21. By rotating or sliding the valve body, the degree to which the valve body obstructs the channel 21 is changed, thereby altering the gas flow rate of the gas outlets 22. The channel 21 can be completely closed or kept unobstructed. The valve body can also be adjusted between maximum flow rate and zero flow rate for precise control.

[0028] The multi-directional pipeline regulating device also includes a linkage component, which is provided with n linkage locking mechanisms, each corresponding to a valve body. The linkage locking mechanism can switch between a locked state and an unlocked state. When in the locked state, the linkage locking mechanism connects the linkage component to the valve body, so that the linkage component drives the valve body to move, thereby changing the flow rate of the channel 21.

[0029] According to the actual cooking scenario, the user can selectively connect the valve body corresponding to the expected gas outlet 22 to the linkage component through the corresponding linkage locking mechanism, thereby linking at least one valve body with the linkage component to achieve individual gas supply or simultaneous supply of gas from multiple gas outlets 22.

[0030] The multi-directional pipeline regulating device also includes a main drive mechanism, which is connected to the linkage component and drives the linkage component to move, thereby moving all valve bodies connected to the linkage component. After the valve bodies move, the flow rate of channel 21 changes synchronously. By using a single main drive mechanism, the flow rate of multiple channels 21 can be changed simultaneously and equally, resulting in lower device cost and better consistency.

[0031] This multi-directional pipeline regulating device can achieve either a single-output gas mode or a simultaneous multi-output gas mode. Initially, all interlocking mechanisms are unlocked. When a single-output mode is needed, the interlocking mechanism corresponding to the selected gas outlet 22 is locked. At this time, the interlocking component connects to the corresponding valve body, causing the interlocking component to move the valve body, thereby changing the flow rate of the gas outlet 22. When multiple gas outlets 22 are needed, the interlocking mechanisms corresponding to multiple gas outlets 22 are locked. The main drive mechanism then drives multiple valve bodies to move together via the interlocking components, allowing each burner to output gas simultaneously and in equal amounts, achieving simultaneous cooking across multiple burners.

[0032] In this embodiment, n=2, and the two gas outlets 22 are symmetrically arranged relative to the main gas inlet. The corresponding components for the two gas outlets 22 are also symmetrically arranged. In the following description, only the components corresponding to one of the gas outlets 22 will be used as an example.

[0033] like Figure 3 and Figure 4 As shown, the valve body includes a gear shaft 12, a blade 11, a spring 16, and a push rod 18.

[0034] The gear shaft 12 is rotatably connected to the air intake base 1. The gear shaft 12 rotates around its own axis. A part of the gear shaft 12 is located inside the channel 21, and a part is located outside the air intake base 1.

[0035] The blade 11 is connected to the gear shaft 12 and located within the channel 21. Changing the rotation angle of the blade 11 alters the flow rate of the channel 21. For example, in this embodiment, the main gas inlet is located at the bottom of the intake base 1, and two gas outlets 22 are located at the front and rear ends of the intake base 1. The main gas inlet and the gas outlets 22 form a 90° angle. When the blade 11 rotates to a completely vertical angle, i.e., perpendicular to the gas outlets 22, the flow rate is 0. As the blade 11 rotates, the flow rate is maximized when it reaches 90°, i.e., in a horizontal state. Figure 8 As shown.

[0036] The air intake base 1 can be assembled from two parts: the base and the top cover 2. Correspondingly, the channel 21 is also formed by the slots on these two parts. This design facilitates the assembly of the valve body.

[0037] like Figure 4 and Figure 5As shown, a portion of the gear shaft 12 is located outside the air intake base 1, and the gear shaft 12 located outside the air intake base 1 is provided with an external thread. The push rod 18 is provided with a threaded hole 20, and the threaded hole 20 is threadedly connected to the external thread.

[0038] like Figure 8 As shown, to ensure smooth rotation of the gear shaft 12, the intake base 1 is equipped with two sealed bearings 10 corresponding to the gear shaft 12. The sealed bearings 10 are connected to the gear shaft 12, and the blade 11 is located between the two sealed bearings 10. Furthermore, to further enhance sealing, a sealing flange 17 is fitted onto the gear shaft 12, connecting the two parts of the intake base 1.

[0039] like Figure 5 and Figure 8 As shown, the push rod 18 is provided with a first locking part. In this embodiment, the first locking part is a groove 19 located at the top of the push rod 18, and the surfaces of the groove 19 facing upward and towards the linkage structure are open.

[0040] like Figure 7 and Figure 8 As shown, the linkage locking mechanism includes a slider 8 and a locking block 9 that can move up and down relative to the slider 8. The locking block 9 is provided with a second engaging portion. In this embodiment, one ridge of the locking block 9 forms the second engaging portion, which can be inserted into the groove 19 of the push rod 18. Because the locking block 9 only moves vertically relative to the slider 8, after the second engaging portion engages with the first engaging portion, the locking block 9 can prevent the push rod 18 from rotating around the gear shaft 12 and has the same movement state as the locking block 9 in the axial direction of the gear shaft 12. When it is necessary to open a certain gas outlet 22, the locking block 9 is moved to lock with the push rod 18. At this time, when the slider 8 moves left and right along the axial direction of the gear shaft 12, since the locking block 9 is locked with the push rod 18, the push rod 18 will move axially together with the slider 8. Since the gear shaft 12 is threadedly connected to the push rod 18, the push rod 18 cannot rotate. Therefore, the gear shaft 12 rotates relative to the push rod 18, thereby driving the blade 11 to rotate to change the flow rate.

[0041] The spring 16 is sleeved on the gear shaft 12 and located between the push rod 18 and the air intake base 1, so that the push rod 18 abuts against the locking block 9. When it is necessary to close this gas outlet 22, the slider 8 moves in the opposite direction. Under the action of the spring 16, the push rod 18 always abuts against the locking block 9 and moves together in the opposite direction along the axial direction, thereby driving the blade 11 to rotate in the opposite direction.

[0042] The slider 8 has n slides, each corresponding to a locking block 9. The locking block 9 is slidably connected within the slide. In this embodiment, the slider 8 extends vertically, and a magnetic element, such as an iron sheet, is provided at the top of the slider 8. The locking block 9 contains an electromagnet. When the electromagnet is energized, it attracts the iron sheet above it, causing the locking block 9 to move to a first position. When the locking block 9 is in the first position, the second locking part separates from the first locking part. When the electromagnet is de-energized, the locking block 9 descends to a second position due to gravity, and the edge of the locking block 9 falls into the groove 19 of the push rod 18. The second locking part connects to the first locking part, and both have the same axial movement. In the initial state, the blade 11 is placed vertically, the electromagnet is energized, and the locking block 9 is attracted to the top of the channel 21.

[0043] like Figure 2 As shown, the main drive mechanism is connected to the slider 8 and is used to drive the slider 8 to move axially along the gear shaft 12. The main drive mechanism can be a common linear drive module. In this embodiment, the main drive mechanism includes a motor 7, a lead screw base 3, and a lead screw 5. The lead screw base is a fixed component, and the air intake base 1 can also be mounted on the lead screw base 3. The motor 7 and the lead screw base 3 are respectively connected to both ends of the lead screw 5. A coupling 6 is provided between the motor 7 and the lead screw, and the motor 7 drives the lead screw 5 to rotate. The lead screw 5 is threadedly connected to the slider 8, and the slider 8 is slidably connected to the lead screw base 3 in a straight line. The lead screw base limits the slider 8 and prevents it from rotating. Under the rotation of the lead screw 5, the slider 8 only moves in the left-right direction (axial direction of the gear shaft 12). Compared with the traditional method, this device can not only realize on / off switching, but also indirectly control the adjustment of gas flow. At the same time, the adjustment using the gear shaft 12 and push rod 18 has strong anti-electronic interference ability and good accuracy and consistency compared with other electronic device adjustments.

[0044] A lead screw bearing 4 is provided on the lead screw base 3, and the lead screw 5 is connected to the lead screw bearing 4.

[0045] To increase sealing, when the blade 11 rotates to the vertical position, the main gas inlet and the gas outlet 22 are disconnected. The inner wall of the channel 21 is provided with a first elastic sealing structure and a second elastic sealing structure facing each other. When the blade 11 is in the position where the flow rate of the channel 21 is 0, the opposite two edges of the blade 11 abut against the first elastic sealing structure and the second elastic sealing structure respectively, so as to reduce the gap between the blade 11 and the inner wall of the channel 21.

[0046] For example Figure 3 and Figure 8As shown, mounting grooves are provided on both the upper and lower inner walls of the channel 21. One mounting groove is used to install the first elastic sealing structure, and the other mounting groove is used to install the second elastic sealing structure. The first and second elastic sealing structures have the same structure, both including an elastic slider 13 and a spring piece 14 connected to each other. The spring piece 14 is disposed in the mounting groove and is located between the bottom of the mounting groove and the elastic slider 13. In its natural state, the two circumferential edges of the elastic slider 13 smoothly transition with the inner wall of the channel 21, that is, they are on the same curved surface. However, the middle part of the elastic slider 13 is slightly higher, that is, closer to the center of the channel 21. When the blade 11 rotates, the edge of the blade 11 first contacts the edge of the elastic slider 13. As the blade 11 rotates, the blade 11 gradually presses the elastic slider 13 and compresses the spring piece 14. Under the elastic force of the spring piece 14, the elastic slider 13 and the edge of the blade 11 can always be in contact, forming a good seal.

[0047] Of course, a main valve can be installed at the main gas inlet, and the main valve can be closed when the gas stove is not in use.

[0048] The working process of this device is as follows: like Figure 7 As shown, before adjustment, i.e. in the initial state, the blade 11 is in a vertical state, the main gas inlet and the gas outlet 22 are disconnected, the electromagnet in the locking block 9 is energized, and the locking block 9 is attracted to the upper part of the slide.

[0049] like Figure 8 As shown, after adjustment, the electromagnet is de-energized, and the motor 7 operates simultaneously. The slider 8 moves to the right under the rotation of the lead screw 5, and the lower right corner of the locking block 9 abuts against the groove 19 of the push rod 18, causing the push rod 18 and slider 8 to move to the right together. During this movement, the spring 16 is compressed. Simultaneously with the push rod 18 moving linearly, the gear shaft 12, threadedly connected to the push rod 18, rotates, causing the blade 11 to rotate and changing the flow rate of the channel 21.

[0050] When it is necessary to close the gas outlet 22, the motor 7 rotates in the reverse direction, the slider 8 moves to the left, and under the elastic action of the spring 16, the push rod 18 is always connected to the locking block 9. After the push rod 18 moves to the left, the gear shaft 12 threadedly connected to the push rod 18 rotates in the reverse direction, the blade 11 reverses, and finally can be positioned in a vertical state (the rotation range of the blade 11 can be achieved by the positioning structure to achieve a rotation range of 0°-90°), and the flow rate of channel 21 is 0.

[0051] The gas stove provided by this invention includes the aforementioned multi-directional pipeline adjustment device. Because the gas stove provided by this invention utilizes the aforementioned multi-directional pipeline adjustment device, it also possesses the advantages of a multi-directional pipeline adjustment device.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
