[0036] See also Figures 1 to 8 The odor diffusion device 100 with diversion function includes a main body 10 and a storage part 20. The main body 10 has an installation space 11, and one side of the installation space 11 has an opening 12. The storage part 20 is installed on a side of the main body 10 relatively close to the opening 12, and the side of the storage part 20 relatively away from the bottom wall of the installation space 11 is used to place odor substances. In other words, the storage part 20 can separate the installation space 11 along the axial direction, and the storage part 20 can provide a placement position for the odor substances between the opening 12 and the bottom wall of the installation space 11, which is convenient for users to take and replace the odor substances. At the same time, when cleaning and maintenance are required, users can only clean the storage part 20 through the opening 12, and can quickly wipe the storage part 20 for reuse, without having to clean the entire main body 10, and use and maintenance are more convenient.

[0037] Furthermore, in order to meet the demand for rapid odor diffusion in different use environments, the odor diffusion device 100 with a diversion function of the present application further includes an accelerating diffusion member 30 , which is disposed in the installation space 11 and can accelerate the odor diffusion speed of the odor substance through the placement member 20 .

[0038] For example, in this embodiment, the accelerating diffusion member 30 includes a heating member 31. That is, the accelerating diffusion member 30 accelerates the odor diffusion speed of the odor substance by heating. In other words, compared with the conventional technology, the present application can heat the placement member 20 by the accelerating diffusion member 30, so that the placement member 20 can transfer heat to the odor substance, that is, the odor substance on the placement member 20 can diffuse rapidly under the catalysis of heat, greatly improving the odor diffusion speed of the odor substance, so that the odor diffusion device 100 with a diversion function can quickly exert its effect in a larger space or a smaller space, and quickly cover the entire space with fragrance.

[0039] It is understandable that in other embodiments, the accelerating diffusion element 30 can also accelerate the odor diffusion rate of the odor substance in other ways, including but not limited to heating, vibration and the like.

[0040] In this embodiment, the peripheral side of the storage element 20 is detachably connected to the inner peripheral wall of the installation space 11 , so that the storage element 20 can be completely removed from the main body 10 for cleaning.

[0041] Furthermore, the odor diffusion device 100 with a diversion function of the present application is more suitable for solid odor substances that can be directly placed on the storage piece 20, and the solid odor substances include but are not limited to tea leaves, flowers, coffee materials, etc.

[0042] In order to facilitate the transfer of heat to the placement member 20, thereby catalyzing and accelerating the emission speed of the odorous substance, the accelerating diffuser 30 is arranged on a side of the installation space 11 close to the placement member 20, or attached to a side of the placement member 20 opposite to the opening 12, or the accelerating diffuser 30 and the placement member 20 can be integrated. As long as the accelerating diffuser 30 can heat the odorous substance on the placement member 20, it can be used.

[0043] Please see again Figures 3 to 8 In order to prevent the odor from being easily dispersed directly from the place where the odor substance is placed, and from being difficult to gather and disperse stably along a specific position, resulting in uneven odor diffusion in low and high spaces in the room, and poor user experience. Furthermore, the odor diffusion device 100 with a flow diversion function also includes a flow guide 90, which is connected to the main body 10 and can form a flow diversion space 1001 on the side where the opening 12 is provided in the installation space 11.

[0044] With such a configuration, the odor diffusion device 100 with a flow guiding function of the present application can form a flow guiding space 1001 above the installation space 11 through the flow guiding member 90, so that the odor emitted by the odorous substance on the storage part 20 can be gathered upward in the flow guiding space 1001 through the flow guiding member 90, and then stably and continuously dispersed through the side of the flow guiding space 1001 relatively far away from the installation space 11, effectively reducing the odor emitted by the odorous substance directly dispersing at the storage part 20, thereby causing most of the odor to be in the low space indoors. In other words, according to demand, the odor can be gathered and stably dispersed upward through the flow guiding member 90, and the odor can overflow from a higher position and then naturally diffuse downward, which can effectively improve the spatial coverage and diffusion uniformity of the odor diffusion.

[0045] In one embodiment, the flow guide 90 is detachably sleeved on the outer peripheral wall of the main body 10 , so that the flow guide 90 can be easily disassembled for cleaning, and the odorous substances on the object placement part 20 can be easily replaced and the object placement part 20 can be cleaned and maintained.

[0046] In one embodiment, the guide member 90 includes a first guide portion 91 and a second guide portion 92 connected to each other, the first guide portion 91 is sleeved on the outer peripheral wall of the main body 10, and the second guide portion 92 forms a guide space 1001 on a side of the installation space 11 where the opening 12 is provided.

[0047] In this way, the first guide part 91 can adapt to the shape of the main body 10, and is easy to connect with the main body 10, and the second guide part 92 can form a guide space 1001 on one side of the installation space 11, thereby relatively guiding the path of the odor. Both can design their own structures according to their respective functions.

[0048] In this embodiment, in order to facilitate processing, the first air guide portion 91 and the second air guide portion 92 are integrally formed.

[0049] In one embodiment, the diameter of the guide member 90 gradually decreases from one end relatively close to the bottom wall of the installation space 11 to one end relatively far away from the bottom wall of the installation space 11; or, the diameter of the second guide portion 92 gradually decreases from one end relatively close to the first guide portion 91 to one end relatively far away from the first guide portion 91.

[0050] In this way, the odor emitted by the odor substance can be gradually gathered upward, so that the concentration of the odor when it is emitted is relatively high and concentrated, and the odor is prevented from being emitted only from the peripheral side of the guide member 90, while no odor is emitted from the middle of the guide member 90. It can be understood that in other embodiments, the diameters of different parts of the guide member 90 can also be set according to needs, which is not limited here.

[0051] Please see again Figures 4 to 6 In one embodiment, the inner end wall of the guide member 90 close to the bottom wall of the installation space 11 is provided with a card interface 93, and the outer peripheral wall of the main body 10 is provided with a step portion 14, and the guide member 90 is placed on the step portion 14 through the card interface 93. In this way, the guide member 90 can be directly placed on the main body 10, and it is convenient and quick to take and put the guide member 90.

[0052] In one embodiment, the protruding position of the step portion 14 is located between the middle and bottom of the main body 10. In this way, the area of ​​the guide member 90 and the main body 10 can be more than half of the main body 10, so that the guide member 90 is not easily separated from the main body 10 due to factors such as collision, and the stability of the guide member 90 after being sleeved to the main body 10 can be relatively guaranteed.

[0053] Furthermore, in order to facilitate the opening and closing of the driving member 50 , the control member 82 and the charging port 83 are both arranged between the step portion 14 and the bottom of the main body 10 , that is, arranged at the portion of the main body 10 where the guide member 90 is not sleeved.

[0054] In one embodiment, the inner peripheral wall of the flow guide 90 is a smooth curved surface. The inner peripheral wall of the flow guide 90 is easily dirty due to long-term contact with odors. Setting the inner peripheral wall of the flow guide 90 as a smooth curved surface makes it easier to clean and maintain the flow guide 90.

[0055] In one embodiment, the outer peripheral wall of the guide member 90 is provided with anti-skid patterns 94. The anti-skid patterns 94 can facilitate the user to safely take and place the guide member 90, and reduce the risk of the guide member 90 falling and being damaged when being taken, placed and cleaned.

[0056] In one embodiment, the guide member 90 is made of a heat-insulating material. Thus, when the accelerating diffuser 30 increases the odor diffusion speed by heating, the guide member 90 can reduce or prevent burns to the user when moving the odor diffusion device 100 with a guide function.

[0057] In one embodiment, at least the portion of the flow guide member 90 that forms the flow guide space 1001 is made of a transparent material.

[0058] With such arrangement, the user can see the situation inside the guide member 90 more clearly and intuitively, which facilitates timely cleaning of the guide member 90 and makes it easier to observe and replenish the odorous substances.

[0059] In order to increase the speed of odor diffusion and wafting to the external space, in one embodiment, the inner wall of the installation space 11 is further provided with an air inlet 113, and the storage member 20 is provided with a ventilation hole 21 connecting the installation space 11 and the opening 12. In other words, the external air can enter between the bottom wall of the installation space 11 and the storage member 20 from the air inlet 113, and can enter between the storage member 20 and the opening 12 from the through hole, so that the odor emitted by the odorous substance on the storage member 20 can be dispersed from the opening 12 to the external space more quickly under the action of the airflow.

[0060] See also Fig. 9 In one embodiment, a barrier net 4 is provided between the accelerating diffusion member 30 and the storage member 20, and the aperture of the barrier net 4 is smaller than the aperture of the ventilation hole 21. The barrier net 4 can prevent smaller odor substances such as tea dregs, flower scraps, etc. from falling from the ventilation hole 21 onto the accelerating diffusion member 30, and avoid directly heating the odor substances and thus generating a burning smell or a fire. Furthermore, there is a preset distance h between the barrier net 4 and the heating member 31. In this way, when tea dregs, flower scraps, etc. fall onto the barrier net 4, they will not be directly heated and burned by the heating member 31.

[0061] Please see again Figure 5 In order to further increase the speed of odor diffusion, in one embodiment, the odor diffusion device 100 with a diversion function further includes a fan 40 disposed in the installation space 11, and the air outlet of the fan 40 faces the storage element 20 and / or the peripheral wall of the installation space 11. In this way, the fan 40 can quickly blow the airflow to the ventilation hole 21 of the storage element 20 through the air inlet hole 113, further accelerating the air flow speed, so that the odor emitted by the odor substance can be quickly diffused into the external space.

[0062] Please see again Figure 5 and Figure 8 In one embodiment, the odor diffusion device 100 with a diversion function further includes a driving member 50 connected to the fan 40, and a plurality of air inlet holes 113 are provided on the bottom wall of the installation space 11, and the plurality of air inlet holes 113 are arranged around the circumference of the driving member 50. The driving member 50 can provide power for the rotation of the fan 40, and the plurality of air inlet holes 113 are arranged around the circumference of the driving member 50, which can provide airflow for the fan 40 while dissipating heat for the driving member 50, thereby extending the service life of the driving member 50.

[0063] Please see again Figure 5 In one embodiment, the bottom wall of the installation space 11 is provided with a first annular wall 114, and all the air inlet holes 113 provided on the bottom wall of the installation space 11 are located within the range surrounded by the first annular wall 114. In this way, the first annular wall 114 can play a guiding role, so that the airflow entering the air inlet hole 113 moves quickly toward the fan 40, and the airflow entering the air inlet hole 113 can be concentrated to the peripheral side of the driving member 50, effectively improving the heat dissipation effect on the driving member 50.

[0064] Please see again Figure 5 In one embodiment, a first partition plate 60 is disposed in the main body 10, and the first partition plate 60 longitudinally divides the installation space 11 into a base space 111 and an airflow space 112. The first partition plate 60 is provided with a flow opening 61 connecting the base space 111 and the airflow space 112. The driving member 50 is disposed in the base space 111, and the fan 40 is disposed at the flow opening 61. In this configuration, the first partition plate 60 can relatively separate the space on the air inlet side and the air outlet side of the fan 40, reduce the risk of mutual interference between the air inlet and the air outlet, and further increase the rate at which the odor diffuses toward the opening 12.

[0065] In one embodiment, the first partition plate 60 extends into the base space 111 with a second annular wall 62, and the fan 40 is located in the annular area surrounded by the second annular wall 62. Such a configuration can relatively protect the fan 40, and prevent the fan 40 from touching other functional parts and causing damage to the fan 40 or other functional parts when it is hit or in other unexpected situations, and the second annular wall 62 can also cooperate to play a guiding role, so that the airflow of the air inlet hole 113 can be concentrated and transported to the fan 40.

[0066] Furthermore, the diameter of the second annular wall 62 is greater than the diameter of the first annular wall 114. With such a configuration, there is a gap between the second annular wall 62 and the first annular wall 114, ensuring that the air inlet hole 113 opened on the peripheral side of the bottom wall space can also deliver the airflow to the fan 40 through the gap. Moreover, the diameter of the second annular wall 62 is greater than the diameter of the first annular wall 114, which can also ensure that the airflow from the air inlet hole 113 of the bottom wall can all reach the fan 40, and the second annular wall 62 will not block the flow of airflow, and can make the airflow after passing over the first annular wall 114 be in the area enclosed by the second annular wall 62, and will not be scattered to other positions.

[0067] Furthermore, along the axial direction of the installation space 11, the radial plane where the extended end of the second annular wall 62 is located is lower than the radial plane where the first annular wall 114 is located. In other words, the radial projection of the second annular wall 62 partially overlaps with the radial projection of the first annular wall 114. This ensures that the airflow can be directly surrounded by the second annular wall 62 after passing through the first annular wall 114, and then all of it is supplied to the fan 40.

[0068] In one embodiment, the odor diffusion device 100 with a diversion function further includes a second partition plate 70, which is disposed between the opening 12 and the first partition plate 60, and the storage member 20 can be placed on the second partition plate 70. The second partition plate 70 is provided with an avoidance through hole 71, and the accelerating diffusion member 30 can be installed on the side of the storage member 20 that is opposite to the opening 12 through the avoidance through hole 71. The avoidance through hole 71 can also ensure that the airflow can normally pass through the ventilation holes 21 and the opening 12 on the storage member 20 from the avoidance through hole 71 in sequence, thereby allowing the odor to diffuse rapidly to the external space.

[0069] Please see again Figure 5 In one embodiment, a support column 81 is further disposed between the first partition plate 60 and the second partition plate 70 to strengthen the support function of the object placement member 20 and ensure the stability of the object placement member 20 .

[0070] Exemplarily, the support column 81 includes a first column body disposed on the first partition plate 60 and a second column body disposed on the second partition plate 70 , and the first column body and the second column body are detachably connected.

[0071] Please see again Figure 5 and Figure 7 In one embodiment, the storage piece 20 is provided with a protruding clamping edge 22 , and the main body 10 is provided with a clamping slot 13 . The storage piece 20 is detachably clamped to the main body 10 through the cooperation of the clamping edge 22 and the clamping slot 13 .

[0072] Please see again Figures 1 to 5In one embodiment, the odor diffusion device 100 with a diversion function further includes a control member 82, which is communicatively connected to the driving member 50 and is used to open and close the driving member 50. Further, the control member 82 includes a control circuit board 821 and a control key 822, the control circuit board 821 is installed in the installation space 11, and is communicatively connected to the driving member 50, and the control key 822 is communicatively connected to the control circuit board 821. The control key 822 can be a button or a touch screen, which can be integrated on the outer peripheral side of the main body 10, or can be independent of the main body 10, such as an APP in a mobile phone, and the user can relatively control the state of the driving member 50 through the APP in the mobile phone.

[0073] Please see again Figure 4 and Figure 5 Furthermore, the odor diffusion device with diversion function 100 is also provided with a charging port 83 for supplying power to the driving member 50 and the control member 82. The odor diffusion device with diversion function 100 is also provided with an indicator light 85, which is integrated with the control member 82 and arranged on the periphery of the main body 10, and can indicate the charging state and the mode of the odor diffusion device with diversion function 100.

[0074] Please see again Figures 4 to 8 In this embodiment, the main body 10 includes an upper shell and a lower seat body connected to each other, and a foot 84 is further provided at the bottom of the lower seat body. The foot 84 can increase the placement stability of the odor diffusion device 100 with a diversion function.

[0075] 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.

[0076] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
