[0037] Smoking equipment is a kitchen appliance commonly used in people's lives. Most smoking equipment on the market are integrated. In existing smoking equipment, the fan blades are generally arranged inside the casing of the smoking equipment, and an air inlet is arranged at the bottom of the smoking equipment. When the smoking equipment is working, the fan blades rotate in a controlled manner and drive the air flow, so that negative pressure can be generated in the casing, and the oil smoke can be sucked into the casing from the air inlet and finally discharged outdoors.
[0038] In the above structure, the fan blades will generate relatively large noise. For an integrated range hood, the air inlet is close to the fan blades, and the noise generated by the fan blades will be discharged from the air inlet. The large noise will cause harm to the user, greatly reducing the user experience of the integrated smoking device.
[0039] Based on the above considerations, in order to solve the above problems, please refer to Figures 1 to 3. One or more embodiments of the present application provide a smoking device 100. By splitting the smoking device 100 into an air inlet unit 10, an air outlet unit 11 and a connecting unit 12, the air outlet unit 11 is equipped with a fan blade 112, and the air inlet unit 10 and the air outlet unit 11 can respectively achieve the suction and discharge of oil smoke. The connecting unit 12 is used to connect between the air inlet unit 10 and the air outlet unit 11, so that the air inlet unit 10 and the air outlet unit 11 can be separated. In this way, the connecting unit 12 can extend the flow path of oil smoke between the air inlet and outlet unit 11 and the air outlet unit 11, and can make the noise source generated by the fan blade 112 in the air outlet unit 11 away from the air inlet, thereby effectively reducing noise propagation and improving user experience.
[0040] Specifically, referring to Figures 1 to 3, the smoking device 100 includes an air inlet unit 10, an air outlet unit 11, and a connecting unit 12. The air inlet unit 10 has an air inlet channel 101 extending therethrough, and the air inlet unit 10 is provided with a first air inlet 102 and a first air outlet 103 connected to the air inlet channel 101. The air outlet unit 11 includes a housing 111, a fan blade 112, and a driving member 113. The housing 111 has an air outlet channel 1111 extending therethrough, and is provided with a second air inlet 1112 and a second air outlet 1113 connected to the air outlet channel 1111. The fan blade 112 and the driving member 113 are both connected to the air outlet channel 1111, and the driving member 113 is used to drive the fan blade 112 to rotate. The connecting unit 12 is connected between the air inlet unit 10 and the casing 111, and has a connecting channel 121 extending in a tortuous manner. The connecting channel 121 connects between the first air outlet 103 and the second air inlet 1112, and one end of the connecting channel 121 close to the casing 111 is constructed to have at least two corners.
[0041] It can be understood that during the operation of the smoking device 100, the driving member 113 drives the fan blades 112 to rotate, so that the fan blades 112 drive the air flow, thereby generating negative pressure in the smoking device 100, and the oil smoke can be sucked into the air inlet channel 101 from the first air inlet 102, and then enter the connecting channel 121 through the first air outlet 103, and then enter the air outlet channel 1111 through the second air inlet 1112, and finally discharged to the outside from the second air outlet 1113.
[0042] It should be further explained that when the smoking device 100 is assembled, the air inlet unit 10 needs to be mounted above the stove, and the opening direction of the first air inlet 102 needs to be towards the stove, so that the fumes generated by the user when cooking can be sucked into the smoking device 100 by the first air inlet 102 at the first time.
[0043] The air outlet unit 11 can be arranged according to actual conditions. For example, the air outlet unit 11 can be connected between the kitchen ceiling and the kitchen ceiling, so as to use the kitchen ceiling to weaken the noise generated by the fan blades 112 in the smoking device 100 to a certain extent.
[0044] The connecting unit 12 is connected between the air outlet units 11 and the air outlet units 11, so that the air outlet units 11 can be flexibly arranged, and the air inlet unit 10 and the air outlet unit 11 can be separated to extend the flow path of oil smoke between the air inlet unit 11 and the air outlet unit 11, and the noise source generated by the fan blades 112 in the air outlet unit 11 can be kept away from the air inlet, thereby effectively reducing noise propagation.
[0045] In addition, the connecting channel 121 is constructed to form a corner, which can change the path of noise propagation in the connecting channel 121, so that the noise sound waves will have impedance mismatch due to the sudden change in space, thereby causing the noise sound waves to be continuously reflected, thereby causing the noise intensity to attenuate, thereby achieving a noise reduction effect.
[0046] In some embodiments, referring to Figures 2 and 5, the connecting unit 12 includes a mounting member 122, a connecting member 123 and a conversion member 124 which are sequentially connected between the air inlet unit 10 and the housing 111, and the mounting member 122, the connecting member 123 and the conversion member 124 all have sub-channels passing therethrough, and the sub-channels are interconnected to form a connecting channel 121 together.
[0047] Further, the specific position of the corner in the connecting channel 121 is not limited. In some embodiments, at least one corner is formed in the sub-channel of the conversion member 124. In other embodiments, at least one corner is formed in the sub-channel of the connecting member 123. In still other embodiments, at least one corner is formed in both the sub-channel of the conversion member 124 and the sub-channel of the connecting member 123.
[0048] It can be understood that the corner can change the path of noise propagation in the connecting channel 121, so that the noise sound waves will have impedance mismatch due to the sudden change in space, thereby causing the noise sound waves to be continuously reflected, thereby causing the noise intensity to attenuate and achieving a noise reduction effect.
[0049] In some embodiments, referring to FIG. 2 and FIG. 5 , the connecting piece 123 is a telescopic pipe.
[0050] It is understandable that the user can adjust the length of the connecting piece 123 according to the actual distance between the air inlet and outlet unit 11 and the air outlet unit 11 to ensure that the connecting unit 12 can be connected between the air inlet unit 10 and the casing 111, which is flexible to use and helps to meet the user's various usage needs.
[0051] In some embodiments, referring to FIG. 2 and FIG. 6 , the first air inlet 102 is circular, and along the flow direction of the airflow in the air outlet channel 1111 , the projection of the fan blade 112 is located within the projection range of the first air inlet 102 .
[0052] It is understandable that the circular edge of the first air inlet 102 can be matched with the circular edge defined by the rotation of the fan blade 112. In this way, the first air inlet 102 can ensure the air intake when the fan blade 112 rotates, which is beneficial to ensure the operating efficiency of the smoking device 100.
[0053] In some embodiments, referring to FIG. 2 and FIG. 5 , the cross-sectional area of the connecting member 123 along the flow direction of the airflow in the connecting channel 121 is rectangular.
[0054] It can be understood that, when the assembly space is certain, setting the connecting piece 123 to a rectangular cross-section can better improve the space occupancy rate and increase the size of the connecting channel 121 compared to the circular cross-section in the prior art, thereby better ensuring the flow of air in the connecting channel 121, which is beneficial to ensuring the operating efficiency of the smoking device 100.
[0055] In some embodiments, referring to Figures 2 and 5, the conversion member 124 is a square-to-circular conversion head. In this way, the conversion member 124 can be assembled with the connecting member 123 with a rectangular cross section and the housing 111 with a circular first air inlet 102 to achieve a better transition between the two and ensure the stability of the assembly of the smoking device 100.
[0056] In some embodiments, referring to Figures 2 and 4, a second air inlet 1112 is provided on the top side surface of the casing 111, and a connecting portion 1114 is protruded from the top side surface of the casing 111, and the end of the connecting portion 1114 facing away from the casing 111 is used to mate with an external top plate, and a spacing is formed between the casing 111 and the external top plate to form an installation space for assembling the connecting unit 12.
[0057] It can be understood that the connecting portion 1114 can be connected to the ceiling of the kitchen so that the casing 111 is suspended on the ceiling of the kitchen, and an installation space is formed between the casing 111 and the external top plate, and the connecting unit 12 can extend into the installation space and mate with the casing 111, and make the connecting channel 121 connected with the air outlet channel 1111 through the second air inlet 1112.
[0058] 2 and 4, the second air outlet 1113 is provided on the peripheral surface of the housing 111. Thus, the second air outlet 1113 opens toward the peripheral wall of the kitchen, so that the user can exhaust the oil smoke to the outside through the external pipe and through the kitchen wall.
[0059] In some embodiments, referring to FIG. 2 and FIG. 4 , the air outlet unit 11 further includes a grille 114 , and the grille 114 is coupled to the second air inlet 1112 of the housing 111 .
[0060] It is understandable that when the fan blades 112 rotate, the airflow will generate vortices, thereby increasing the noise volume. The present application sets a grille 114 at the second air inlet 1112 to correct the airflow direction by using the grille 114 to avoid the generation of vortices, thereby reducing noise.
[0061] In some embodiments, referring to FIG. 2 and FIG. 4 , the air outlet unit 11 further includes a check valve 115 , and the check valve 115 is connected to the second air outlet 1113 of the housing 111 .
[0062] It is understandable that the check valve 115 can prevent oil smoke or external airflow from flowing back into the smoking device 100 , which is helpful to ensure the hygiene and safety of the smoking device 100 .
[0063] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0064] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
