[0057] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0058] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0059] In the embodiments of the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used to describe the relative positional relationship of components with respect to the directions shown in the drawings or in the vertical, perpendicular or gravity directions.

[0060] The present invention will be described in detail below in conjunction with exemplary embodiments with reference to the accompanying drawings.

[0061] like Figures 3 to 8As shown, the first exemplary embodiment of the present invention provides an air intake module, which includes an air intake cover 1, a lever-type lifting mechanism and a trigger control mechanism. The air intake cover 1 can move vertically and is provided with an air intake channel and an air inlet connected to the air intake channel. When the air intake module is working, a negative pressure can be formed at the air inlet to guide the external airflow into the air intake channel. The lever-type lifting mechanism can form a lever pivoting action, and under the action of the lever pivoting action, the air intake cover 1 can be lifted to shorten the flow path required for the external airflow to enter the air inlet. The trigger control mechanism is used to trigger the lever-type lifting mechanism to form a lever pivoting action, and the trigger control mechanism can be manually controlled.

[0062] When the air inlet module is installed on the stove top of the integrated stove for absorbing oil smoke, the air inlet hood 1 can move between the upper dead point position (i.e. the highest point position) and the lower dead point position (i.e. the lowest point position). When it is at the lower dead point position, the top surface of the air inlet hood 1 is flush with the top surface of the stove top. When it is at the upper dead point position, the air inlet hood 1 at least partially extends upward from the top surface of the stove top.

[0063] In the case where the air inlet hood 1 is provided with a vertical air inlet, smoking can be performed normally even when the air inlet hood 1 is at the bottom dead center. If the smoking efficiency is to be improved, the lever-type lifting mechanism can be triggered by controlling the trigger control mechanism to form a lever pivoting action to lift the air inlet hood 1 to the top dead center position. At this time, the height difference between the air inlet and the cooking utensils next to it is greatly reduced, so that the oil smoke originally flowing upward in the cooking utensils can flow into the air inlet without a large downward turn, thereby reducing the dispersion of oil smoke and improving the smoking efficiency, thereby effectively improving the smoking effect.

[0064] In one embodiment, the lever-type lifting mechanism includes a lever-type transmission arm, which includes a lever fulcrum portion and a power arm section and a resistance arm section located on both sides of the lever fulcrum portion. At this time, the air inlet cover 1 is connected to the resistance arm section, and the trigger control mechanism can act on the power arm section, so that the power arm section drives the entire lever-type transmission arm to pivot around the lever fulcrum portion while pivoting, thereby lifting the air inlet cover 1.

[0065] It can be seen that in this embodiment, the lifting action of the air inlet cover 1 can be achieved by only providing a lever-type transmission arm with a simple structure and a simple transmission method, which is beneficial to saving assembly space and cost, reducing production difficulty and improving production efficiency, etc. Of course, in some other embodiments, a more complex structure can be provided in the lever-type lifting mechanism, for example, multiple lever-type transmission arms can be provided and form specific pivotal connections with each other, so that the lever pivoting action of the lever-type lifting mechanism includes a folding action.

[0066] In one embodiment, the lever-type transmission arm includes a first transmission arm 3 and a second transmission arm 4, the lever fulcrum portion includes a first fulcrum portion 3b in the first transmission arm 3 and a second fulcrum portion 4b in the second transmission arm 4, the first transmission arm 3 includes a first power arm segment and a first resistance arm segment located on both sides of the first fulcrum portion 3b, and the second transmission arm 4 includes a second power arm segment and a second resistance arm segment located on both sides of the second fulcrum portion 4b. The first pivot axis of the first fulcrum portion 3b is parallel to and spaced from the second pivot axis of the second fulcrum portion 4b, the first power arm segment and the second power arm segment extend toward each other, the first resistance arm segment and the second resistance arm segment extend away from each other and are both connected to the air inlet hood 1, that is, the first resistance arm segment and the second resistance arm segment are connected to the lateral sides of the air inlet hood 1, respectively. Under this structure, the shaking of the air inlet hood 1 during the vertical movement can be effectively reduced, thereby improving stability and reliability.

[0067] In addition, in order to ensure the stable lifting of the air inlet cover 1, the trigger control mechanism can be set to drive the first transmission arm 3 and the second transmission arm 4 to pivot synchronously. There are two cases in which the first transmission arm 3 and the second transmission arm 4 pivot synchronously: the first case is that the first transmission arm 3 and the second transmission arm 4 form a linkage, and when the trigger control mechanism acts on at least one of the first transmission arm 3 and the second transmission arm 4, the first transmission arm 3 and the second transmission arm 4 can be driven to pivot synchronously; the second case is that the first transmission arm 3 and the second transmission arm 4 do not form a linkage, and at this time, it is necessary to ensure that the trigger control mechanism can act on the first transmission arm 3 and the second transmission arm 4 at the same time to make the two pivot synchronously.

[0068] In one embodiment, when the first transmission arm 3 and the second transmission arm 4 form a linkage, the inner end of the first power arm segment of the first transmission arm 3 and the inner end of the second power arm segment of the second transmission arm 4 facing each other can be arranged to form a meshing transmission connection. Figure 6 A standard involute tooth profile may be formed at the inner end of the first power arm segment and the inner end of the second power arm segment to form a meshing transmission connection, or other tooth profiles may be formed to form a meshing transmission connection.

[0069] Furthermore, the first power arm section forms a first pivot trigger part 3a, and the second power arm section forms a second pivot trigger part 4a. At this time, the trigger control mechanism can act on the first pivot trigger part 3a alone, act on the second pivot trigger part 4a alone, or act on the first pivot trigger part 3a and the second pivot trigger part 4a synchronously, so as to drive the first transmission arm 3 and the second transmission arm 4 to pivot synchronously.

[0070] In one embodiment, when the first transmission arm 3 and the second transmission arm 4 are not linked, the trigger control mechanism can be configured to act synchronously on the first pivot trigger portion 3a and the second pivot trigger portion 4a to drive the first transmission arm 3 and the second transmission arm 4 to pivot synchronously.

[0071] In one embodiment, the lever-type transmission arm further includes a third transmission arm 5 and a fourth transmission arm 6, wherein the third transmission arm 5 includes a third fulcrum portion and a third power arm segment and a third resistance arm segment located on both sides of the third fulcrum portion, and the fourth transmission arm 6 includes a fourth fulcrum portion and a fourth power arm segment and a fourth resistance arm segment located on both sides of the fourth fulcrum portion. At this time, the first transmission arm 3 and the second transmission arm 4 are provided on one lateral side of the air inlet hood 1, and the third transmission arm 5 and the fourth transmission arm 6 are provided on the other side. Among them, the third pivot axis of the third fulcrum portion coincides with the first pivot axis of the first fulcrum portion 3b, the fourth pivot axis of the fourth fulcrum portion coincides with the second pivot axis of the second fulcrum portion 4b, the third power arm segment and the fourth power arm segment extend toward each other, respectively, and the third resistance arm segment and the fourth resistance arm segment extend away from each other and are both connected to the air inlet hood 1. In other words, the third resistance arm segment and the fourth resistance arm segment are respectively connected to the lateral sides of the air inlet hood 1, and the third resistance arm segment and the first resistance arm segment are connected to the same side of the air inlet hood 1, and the fourth resistance arm segment and the second resistance arm segment are connected to the same side of the air inlet hood 1. With this structure, shaking of the air inlet cover 1 during vertical movement can be basically avoided, thereby further improving stability and reliability.

[0072] In one embodiment, the lever-type lifting mechanism further includes a first support link 7 and a second support link 8, the two ends of the first support link 7 are respectively connected to the first resistance arm segment and the third resistance arm segment, the two ends of the second support link 8 are respectively connected to the second resistance arm segment and the fourth resistance arm segment, and the first resistance arm segment and the third resistance arm segment are connected to the air inlet hood 1 through the first support link 7, and the second resistance arm segment and the fourth resistance arm segment are connected to the air inlet hood 1 through the second support link 8. Under this structure, the first transmission arm 3 and the third transmission arm 5 form a linkage and can be synchronously pivoted, and the second transmission arm 4 and the fourth transmission arm 6 form a linkage and can be synchronously pivoted, so when the first transmission arm 3 and the second transmission arm 4 form a linkage, the first transmission arm 3, the second transmission arm 4, the third transmission arm 5 and the fourth transmission arm 6 can be synchronously pivoted, so that there is a greater driving force to lift the air inlet hood 1.

[0073] Furthermore, a first groove and a second groove (both belonging to the lower structure of the groove 1c) that are recessed inwards can be formed on the outer peripheral walls on both sides of the air inlet cover 1, and the first support link 7 is embedded in the first groove and the second support link 8 is embedded in the second groove. Under this structure, when the air inlet cover 1 moves vertically, since the lever fulcrum of the lever-type transmission arm is fixed and the arm length of the transmission arm remains unchanged, the support link will generate a certain lateral displacement in the groove 1c to prevent it from getting stuck, thereby ensuring that the air inlet cover 1 can be smoothly raised and lowered.

[0074] In one embodiment, in order to make the overall structure of the air inlet module more compact and simplified, a pivot bracket can be provided in the lever-type lifting mechanism, and the lever fulcrum of each lever-type transmission arm can be connected to the pivot bracket. For example, in an embodiment with a first transmission arm 3, a second transmission arm 4, a third transmission arm 5 and a fourth transmission arm 6, the pivot bracket includes a first pivot bracket 9 and a second pivot bracket 10, and the first fulcrum portion 3b and the second fulcrum portion 4b are both connected to the first pivot bracket 9, and the third fulcrum portion and the fourth fulcrum portion are both connected to the second pivot bracket 10.

[0075] In one embodiment, the lever-type lifting mechanism further includes a locking elastic member 11, one end of which is fixed (for example, it can be fixedly connected to the above-mentioned pivot bracket), and the other end is connected to the resistance arm section of the lever-type transmission arm, and the locking elastic member 11 is configured to keep the air inlet cover 1 at the top dead center position. In other words, when the air inlet cover 1 is at the top dead center position, the locking elastic member 11 has a locking effect on the air inlet cover 1, and the locking elastic member 11 can be different types of elastic members such as a tension spring or a gas spring.

[0076] In one embodiment, the trigger control mechanism can be manually controlled and includes a key outer bracket 12 and a key body. The key outer bracket 12 is fixedly arranged and formed with a key limit groove 12a, the key body can be elastically pressed in the key outer bracket 12, and the key body includes an outer pressing plate 13, a key driving part 14 capable of acting with the power arm section, and a key limit part 15 extending into the key limit groove 12a. When the outer pressing plate 13 is manually pressed, the key driving part 14 can be driven to move downward synchronously, and the key limit part 15 is extended into the key limit groove 12a, so that the key limit part 15 can only slide in the groove, thereby limiting the vertical movement range of the key body.

[0077] The following is an explanation of how to manually control the trigger control mechanism to lift the air inlet hood 1 to the top dead center position and how to reset the air inlet hood 1 to the bottom dead center position in conjunction with the embodiments in the accompanying drawings.

[0078] Specifically, in the illustrated embodiment, the bottom wall of the key outer bracket 12 is connected to a positioning column 12b, and the key body also includes a key spring 16 sleeved on the positioning column 12b, the bottom end of the key spring 16 abuts against the bottom wall of the key outer bracket 12 and the top end abuts against the external pressing plate 13.

[0079] When the air inlet cover 1 is Figure 4 The bottom dead center position in the Figure 5 When the button driving part 14 reaches the upper dead center position, the outer pressing plate 13 can be pressed downward to drive the button driving part 14 to move downward. During the downward movement, the button driving part 14 will be pressed against the first pivot trigger part 3a and the second pivot trigger part 4a at the same time. Since the inner end of the first transmission arm 3 forms a meshing transmission connection with the inner end of the second transmission arm 4, the first power arm segment and the second power arm segment can pivot downward at the same time to make the first resistance arm segment and the second resistance arm segment pivot upward at the same time, and drive the third resistance arm segment and the fourth resistance arm segment to pivot upward at the same time through the first support link 7 and the second support link 8, thereby lifting the air inlet hood 1 from the lower dead center position to the upper dead center position.

[0080] In the above process, when the pressing force on the outer pressing plate 13 is removed, the outer pressing plate 13 will move upward due to the rebound effect of the key spring 16, and under the limiting effect of the key limiting groove 12a, the outer pressing plate 13 can move up to the initial position and stop.

[0081] In addition, in the illustrated embodiment, the locking elastic member 11 includes a first tension spring and a second tension spring. The outer end of the first tension spring is fixedly connected to the second resistance arm section and the inner end is fixedly connected to the first pivot bracket 9, and the inner end of the first tension spring is arranged higher than the second fulcrum portion 4b of the second transmission arm 4. The outer end of the second tension spring is fixedly connected to the third resistance arm section and the inner end is fixedly connected to the second pivot bracket 10, and the inner end of the second tension spring is arranged higher than the third fulcrum portion of the third transmission arm 5. In addition, the first tension spring and the second tension spring are always in a tensioned state.

[0082] By setting the above structure, when the air inlet cover 1 is lifted to the top dead center position, the second resistance arm section is subjected to the first tension force of the first tension spring, and the first tension force has a larger component in the vertical direction and is directed upward. Similarly, the third resistance arm section is subjected to the second tension force of the second tension spring, and the second tension force has a larger component in the vertical direction and is directed upward. At this time, under the joint action of the first tension force and the second tension force, the air inlet cover 1 can always be maintained at the top dead center position.

[0083] When the air inlet cover 1 is Figure 5 The top dead center position in Figure 4When the air inlet hood 1 reaches the lower dead point position, the air inlet hood 1 can be directly pressed downward to the lower dead point position. At this time, although the first tension spring and the second tension spring still generate tension on the second resistance arm segment and the third resistance arm segment respectively, since the tension spring follows the lever-type transmission arm to pivot at a certain angle, the spring tension is not enough to overcome the force generated by the air inlet hood 1 on the first support link 7 and the second support link 8 to drive the transmission arm to pivot, so the air inlet hood 1 can be maintained at the lower dead point position.

[0084] In one embodiment, when the trigger control mechanism triggers the lever pivoting action, the power arm length between the trigger control mechanism and the lever fulcrum portion can be set to be smaller than the resistance arm length between the air inlet cover 1 and the lever fulcrum portion. At this time, a large stroke on the resistance side can be obtained by a small stroke on the power side of the transmission arm. For example, in the illustrated embodiment, the air inlet cover 1 can be moved upward by a large distance by simply pressing the button body downward by a short distance, so that it is easier to achieve control.

[0085] In one embodiment, the air inlet includes a vertical air inlet arranged on the top surface of the air inlet hood 1 and a plurality of transverse air inlets 1a arranged on the outer peripheral wall of the air inlet hood 1. A plurality of concentrically arranged annular grilles 1b may be provided in the vertical air inlet to reduce turbulence. The air inlet module may include a main bracket 2, and the main bracket 2 is provided with an annular wind shield 2c extending vertically. Under this structure, when the air inlet hood 1 is located at the lower dead point position, the air inlet module can still take in air through the vertical air inlet, but at this time the air inlet hood 1 and the annular wind shield 2c are mutually nested, so that the annular wind shield 2c blocks the transverse air inlet 1a to prevent the airflow in the air inlet channel from flowing out through the transverse air inlet 1a, especially when the airflow contains pollutants such as oil smoke, it can avoid causing pollution outside the air inlet module.

[0086] In addition, a positioning bracket 2a may be provided on the main bracket 2, and the aforementioned pivot bracket may be fixed on the main bracket 2, and the lever fulcrum of the lever-type transmission arm may be pivotally connected between the positioning bracket 2a and the pivot bracket. A bracket limiting portion 2b may be provided on the positioning bracket 2a, and a body limiting groove may be provided on the key body. In this case, the bracket limiting portion 2b extends into the body limiting groove, and the vertical travel of the key body can also be limited.

[0087] The second exemplary embodiment of the present invention provides an oil fume purification device using the above-mentioned air intake module. Obviously, the oil fume purification device has all the technical effects brought by the above-mentioned air intake module due to the use of the above-mentioned air intake module, which will not be repeated here. However, it should be noted that the air intake module in the first exemplary embodiment of the present invention can also be used in other types of air purification devices, not just limited to oil fume purification devices.

[0088] like Figure 1 and Figure 2As shown, the third exemplary embodiment of the present invention provides an integrated stove, which includes a stove 17 and the above-mentioned oil fume purification device located below the stove 17. Similarly, due to the use of the above-mentioned oil fume purification device, the integrated stove in this exemplary embodiment has all the technical effects brought by it, so it will not be repeated.

[0089] Specifically, the stove 17 is provided with an air inlet cover embedding opening 17a which is vertically penetrated, and the air inlet cover 1 is embedded in the air inlet cover embedding opening 17a. At the bottom dead point, the top surface of the air inlet cover 1 is flush with the top surface of the stove 17. If the air inlet cover 1 is provided with a vertical air inlet, the air inlet cover 1 at the bottom dead point can also be used for smoking. At the top dead point, the air inlet cover 1 at least partially extends upward from the air inlet cover embedding opening 17a, which can effectively improve the smoking effect.
