Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to a fragrance device, air conditioning system and carrier. Background Technology

[0002] Passenger cabins in vehicles such as flying cars are generally equipped with fragrance systems. There are generally three ways to add fragrance: the first is to drive the fragrance to evaporate by a forced airflow from a fan; the second is to accelerate the evaporation by heating the perfume balm or oil with an electric heating element; and the third is to connect the fragrance box in parallel to the main air duct of the air conditioner and supplement it with a small motor or heating element to enhance the effect.

[0003] However, additional components such as fans, motors, and heating elements increase the weight of the vehicle and continuously consume electrical energy, directly affecting the vehicle's range. The operation of the fans generates noise pollution, and the motors and heating elements are at risk of mechanical wear and thermal failure, and may also generate electromagnetic interference, threatening the safety of the avionics system. At the same time, additional components such as fans, motors, and heating elements, as well as their associated heat dissipation and noise reduction structures, increase the complexity, manufacturing difficulty, and maintenance burden of the fragrance device. Utility Model Content

[0006] Preferably, the housing includes a cover and a mounting tube, the cover having a first connection port and a second connection port, the cover having a mounting cavity, and both the first connection port and the second connection port communicating with the mounting cavity; Both ends of the mounting tube are fixed to the inner sidewall of the cover. The mounting tube encloses the connection channel. The mounting tube has two connecting grooves that communicate with the connection channel. The two connecting grooves face each other in a predetermined direction. The first connection port and the second connection port are respectively located on both sides of the mounting tube in the predetermined direction.

[0007] Preferably, the fragrance mechanism includes a fixed tube and a fragrance stick. The fixed tube surrounds a fixed cavity and has two facing transition grooves that communicate with each other. A portion of the fragrance stick is disposed within the fixed cavity, and there is a gap between the fragrance stick and the cavity wall of the fixed cavity. A portion of the fixed tube is located within the mounting cavity and fits against the inner wall of the mounting cavity. The fixed tube is rotatable within the mounting cavity.

[0008] Preferably, the fragrance mechanism further includes a force-applying component, which is connected to the end of the fragrance stick; The fixed tube has a replacement port that communicates with the fixed cavity. Part of the force-applying component is located inside the fixed cavity and abuts against the cavity wall of the fixed cavity. The other part of the force-applying component extends out from the replacement port.

[0009] Preferably, the groove wall of the connecting groove includes two first limiting surfaces facing each other in the circumferential direction of the mounting pipe, and the groove wall of the transition groove includes two second limiting surfaces facing each other in the circumferential direction of the fixing pipe. The included angle between the two first limiting surfaces is equal to the included angle between the two second limiting surfaces. The included angle between the two first limiting surfaces is greater than or equal to 30 degrees and less than or equal to 80 degrees.

[0010] Preferably, a marking line is provided on the outer wall of the cover, and multiple scale lines are provided on the portion of the fixing tube located outside the mounting cavity. The multiple scale lines are spaced apart around the outer wall of the mounting tube, and one of the scale lines is directly opposite the marking line.

[0011] Preferably, the ratio of the area of ​​the cross-section of the fragrance channel corresponding to the outlet to the area of ​​the cross-section of the fragrance channel corresponding to the inlet is 1.5-4.0:1.

[0012] Preferably, the connecting body encloses a transition channel, which is connected to the fragrance channel, and the cross-sectional area of ​​the transition channel gradually increases in the direction away from the fragrance channel.

[0013] Preferably, the fragrance device further includes two flexible tubes, one of which is connected at both ends to the first connection port and the outlet, and the other of which is connected at both ends to the second connection port and the inlet, and the flexible tubes are deformable.

[0014] According to a second aspect of this application, an air conditioning system is provided, the air conditioning system including an air conditioner and the above-mentioned fragrance device, wherein the air conditioner is connected to the connecting body so that the air outlet of the air conditioner is connected to the first end of the fragrance channel.

[0016] According to a third aspect of this application, a vehicle is provided, the vehicle including the air conditioning system described above.

[0017] In use of the fragrance device of this application, the air conditioner is connected to the connecting body so that the air outlet of the air conditioner communicates with the first end of the fragrance channel to supply gas into the fragrance channel. In the direction from the first end to the second end of the fragrance channel, the cross-sectional area of ​​the fragrance channel gradually decreases. Based on the Venturi effect, the gas pressure decreases as the gas flows from the first end to the second end of the fragrance channel. Since the connecting body has an outlet and an inlet, and the outlet is located on the side of the inlet closer to the first end of the fragrance channel, the gas pressure at the outlet is greater than the gas pressure at the inlet. Thus, the gas can flow through the outlet to the first connection port, and then through the connecting channel, the second connection port, and the inlet back into the fragrance channel. When the gas flows through the connecting channel, it can carry fragrance molecules from the fragrance mechanism, allowing the gas carrying fragrance molecules to flow through the second end of the fragrance channel into the passenger compartment. Thus, there is no need for additional components such as fans, motors, and heating elements, reducing the vehicle's weight and eliminating the need for electrical energy consumption, thereby ensuring the vehicle's range. Furthermore, the fragrance device of this application achieves fragrance addition, avoiding noise pollution from fan operation, the risk of mechanical wear and thermal failure of motors and heating elements, and electromagnetic interference. Additionally, the fragrance device of this application does not require supporting heat dissipation and noise reduction structures, reducing the complexity, manufacturing difficulty, and maintenance burden of the fragrance device.

[0030] According to a first aspect of this application, a fragrance device is provided, such as... Figures 1 to 5 As shown, the fragrance device includes a fragrance module 1 and a connecting body 2. The connecting body 2 encloses a fragrance channel 21. The cross-sectional area of ​​the fragrance channel 21 gradually decreases from the first end to the second end. The connecting body 2 has an outlet 27 and an inlet 28, both of which are connected to the fragrance channel 21. The outlet 27 is located on the side of the inlet 28 closest to the first end of the fragrance channel 21. The fragrance module 1 includes a housing 11 and a fragrance mechanism 12. The housing 11 encloses a connecting channel 1121. The housing 11 has a first connection port 114 and a second connection port 115, which are connected to both ends of the connecting channel 1121, respectively. At least a portion of the fragrance mechanism 12 is located within the connecting channel 1121. The first connection port 114 is connected to the outlet 27, and the second connection port 115 is connected to the inlet 28.

[0031] When the fragrance device of this application is used, an air conditioner is connected to the connecting body 2 so that the air outlet 6 of the air conditioner is connected to the first end of the fragrance channel 21 to supply gas into the fragrance channel 21. In the direction from the first end of the fragrance channel 21 to the second end, the cross-sectional area of ​​the fragrance channel 21 gradually decreases. Based on the Venturi effect, the gas pressure decreases as the gas flows from the first end to the second end of the fragrance channel 21. Since the connecting body 2 has an outlet 27 and an inlet 28, with the outlet 27 located on the side of the inlet 28 closer to the first end of the fragrance channel 21, the gas pressure at the outlet 27 is greater than the gas pressure at the inlet 28. In this way, the gas can flow through outlet 27 to the first connection port 114, and then return to the fragrance channel 21 through connection channel 1121, the second connection port 115, and inlet 28. As the gas flows through connection channel 1121, it carries fragrance molecules from the fragrance mechanism 12, allowing the fragrance-laden gas to flow to the passenger compartment through the second end of fragrance channel 21. This eliminates the need for additional components such as fans, motors, and heating elements, reducing the vehicle's weight and ensuring its range without consuming electrical energy. Furthermore, the fragrance device of this application avoids noise pollution from fan operation, mechanical wear and thermal failure risks associated with motors and heating elements, and electromagnetic interference. Additionally, the fragrance device of this application does not require a heat dissipation or noise reduction structure, reducing the complexity, manufacturing difficulty, and maintenance burden of the fragrance device.

[0032] In the embodiments of this application, such as Figure 2 As shown, the connecting body 2 encloses a transition channel 22, which connects to the fragrance channel 21. The cross-sectional area of ​​the transition channel 22 gradually increases in the direction away from the fragrance channel 21. The end of the transition channel 22 away from the fragrance channel 21 can directly supply air to the passenger compartment, or connect to the air outlet 7, thereby supplying air to the passenger compartment through the air outlet 7. The transition channel 22 is designed with a gradually increasing cross-sectional area to reduce airflow resistance, ensuring sufficient airflow into the passenger compartment.

[0033] like Figure 1 and Figure 2 As shown, the connecting body 2 includes a first plate 23, a second plate 24, a third plate 25, and a fourth plate 26. The first plate 23, the third plate 25, and the fourth plate 26 are flat plates, the second plate 24 is an upwardly curved plate, the two ends of the third plate 25 are connected to the first plate 23 and the second plate 24 respectively, and the two ends of the fourth plate 26 are connected to the first plate 23 and the second plate 24 respectively. The fragrance channel 21 is located on the left side and its cross-sectional area gradually decreases, the transition channel 22 is located on the right side and its cross-sectional area gradually increases, the outlet 27 is located near the left end of the curved plate, and the inlet 28 is located in the middle of the curved plate.

[0034] Optionally, the fragrance device may also include two first extension tubes 4, which may be integrally formed with the connecting body 2. The two first extension tubes 4 are respectively connected to the outlet 27 and the inlet 28. Each of the two first extension tubes 4 may be provided with a mounting connector 5, thereby realizing the connection between the first extension tube 4 and the first mounting tube 112 or the second mounting tube 112.

[0035] It should be noted that the shape of the connecting body 2 is not limited to... Figure 1 , Figure 2 and Figure 6 As shown in the figure, the connecting body 2 can be set to a circular, elliptical, or rectangular shape, provided that the cross-sectional area requirements of the fragrance channel 21 and the transition channel 22 are met.

[0036] Preferably, the ratio of the cross-sectional area of ​​the fragrance channel 21 at the outlet 27 to the cross-sectional area of ​​the fragrance channel 21 at the inlet 28 is 1.5-4.0:1, thereby creating a pressure difference greater than 20 Pa between the outlet 27 and the inlet 28 to meet the flow requirements of gas returning to the fragrance channel 21 via the outlet 27, the first mounting pipe 112, the first connection port 114, the connecting channel 1121, the second connection port 115, the second mounting pipe 112, and the inlet 28.

[0037] With the air conditioner's air output as 1 -5 For example, the air intake volume of fragrance channel 21 is 1. -5 The area of ​​the cross-section at the outlet 27 of the fragrance channel 21 is set to 50. At this time, the gas flow velocity at the outlet 27 corresponding to the fragrance channel 21 is 3.33. -16.673 To create a pressure difference greater than 20 Pa between the outlet 27 and the inlet 28, the ratio of the cross-sectional area of ​​the fragrance channel 21 at the inlet 28 to the cross-sectional area of ​​the inlet 28 needs to be greater than 2.0. The cross-sectional area of ​​the fragrance channel 21 at the outlet 27 is set to 100. At this time, the gas flow velocity at the outlet 27 corresponding to the fragrance channel 21 is 1.67. -8.33 In order to create a pressure difference greater than 20 Pa between the outlet 27 and the inlet 28, the ratio of the area of ​​the cross section of the fragrance channel 21 at the inlet 28 to the area of ​​the inlet 28 needs to be greater than 3.6.

[0038] Optionally, when both the outlet 27 and the inlet 28 are circular holes, the cross-section of the fragrance channel 21 corresponding to the location of the outlet 27 can be the cross-section at the center of the outlet 27, and the cross-section of the fragrance channel 21 corresponding to the location of the inlet 28 can be the cross-section at the center of the inlet 28. When the outlet 27 and the inlet 28 are of other shapes, the cross-section of the fragrance channel 21 corresponding to the location of the outlet 27 can be the cross-section at the geometric center of the outlet 27, and the cross-section of the fragrance channel 21 corresponding to the location of the inlet 28 can be the cross-section at the geometric center of the inlet 28.

[0039] In the embodiments of this application, such as Figure 2 , Figure 3 and Figure 4 As shown, the housing 11 includes a cover 111, a mounting tube 112 and two second extension tubes 113. The cover 111, the mounting tube 112 and the two second extension tubes 113 can be integrally formed. The cover 111 has a first connection port 114 and a second connection port 115. The two second extension tubes 113 are respectively connected to the first connection port 114 and the second connection port 115.

[0040] Optionally, the fragrance device also includes two flexible tubes 3. One flexible tube 3 has its two ends connected to the first mounting connector 5 and the outlet 27, respectively, and the other flexible tube 3 has its two ends connected to the second mounting connector 5 and the inlet 28, respectively. Because the flexible tubes 3 are deformable, the fragrance module 1 can be flexibly arranged in different locations according to the layout of the cabin. For example, the fragrance module 1 can be placed below the instrument panel or in the interior space, which facilitates centralized management; for another example, the fragrance module 1 can be placed near the seats to facilitate passengers in replacing or adjusting the intensity of the fragrance stick 122; for yet another example, the fragrance module 1 can be placed in a reserved compartment in the side wall or ceiling, which utilizes the unused space in the cabin and maintains its cleanliness and aesthetics; for yet another example, when the fragrance device is used in a flying car, the fragrance module 1 can be placed in a dedicated service panel area for easy maintenance and replacement by the crew or ground staff.

[0041] Optionally, the flexible tube 3 can be a deformable tube structure such as a plastic tube or a rubber tube.

[0042] like Figure 3 and Figure 4As shown, both ends of the mounting pipe 112 are connected to the inner wall of the housing 111. The mounting pipe 112 forms a connecting channel 1121. The mounting pipe 112 has two connecting grooves 1122 communicating with the connecting channel 1121. The two connecting grooves 1122 face each other in a predetermined direction L. The first connecting port 114 and the second connecting port 115 are located on opposite sides of the mounting pipe 112 in the predetermined direction L. In this way, gas can enter the mounting cavity 1111 from the side where the first connecting port 114 is located, then enter the connecting channel 1121 through one connecting groove 1122, then flow to the side where the second connecting port 115 is located in the mounting cavity 1111 through the other connecting groove 1122, and then flow out through the second connecting port 115.

[0043] It should be noted that the predetermined direction L here is determined based on the positions of the two connecting grooves 1122. When the position of the connecting grooves 1122 changes, the predetermined direction L will also change accordingly.

[0044] Furthermore, the fragrance mechanism 12 includes a fixing tube 121 and a fragrance stick 122. The fixing tube 121 surrounds a fixing cavity 1211. The fixing tube 121 has two facing transition grooves 1212, which communicate with the fixing cavity 1211. The fragrance stick 122 is disposed in the fixing cavity 1211, and there is a gap between the fragrance stick 122 and the cavity wall of the fixing cavity 1211. A portion of the fixing tube 121 is located in the mounting cavity 1111 and fits against the inner side wall of the mounting cavity 1111. The fixing tube 121 can rotate within the mounting cavity 1111. Thus, by rotating the fixed tube 121, the two transition grooves 1212 can be connected to the two connecting grooves 1122 respectively, allowing gas to flow out through the connecting groove 1122 on the side of the first connection port 114, the first transition groove 1212, the gap between the fragrance stick 122 and the cavity wall of the fixed cavity 1211, the second transition groove 1212, and the connecting groove 1122 on the side of the second connection port 115. When the fixed tube 121 is rotated to the position where both transition grooves 1212 correspond to the two connecting grooves 1122 on the part of the fixed tube 121 without transition grooves 1212, gas cannot pass through, and the fragrance module 1 cannot deliver gas carrying fragrance molecules to the fragrance channel 21.

[0045] Furthermore, the groove wall of the connecting groove 1122 includes two first limiting surfaces S1 facing each other in the circumferential direction of the mounting tube 112, and the groove wall of the transition groove 1212 includes two second limiting surfaces S2 facing each other in the circumferential direction of the fixing tube 121. The included angle between the two first limiting surfaces S1 is equal to the included angle between the two second limiting surfaces S2. The included angle between the two first limiting surfaces S1 is greater than or equal to 30 degrees and less than or equal to 80 degrees.

[0046] Optionally, the included angle between the two first limiting surfaces S1 can be 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, or 80 degrees.

[0047] In addition, a marking line is provided on the outer wall of the housing 111, and multiple scale lines are provided on the portion of the fixing tube 121 located outside the mounting cavity 1111. These scale lines are spaced apart around the outer wall of the mounting tube 112, with one scale line aligned with the marking line. By rotating the fixing tube 121, the marking line can be aligned with different scale lines, thereby changing the area of ​​communication between the adapter groove 1212 and the connecting groove 1122, thus adjusting the fragrance intensity.

[0048] Preferably, a scale value can be marked on each scale line on the cover 111.

[0049] Optionally, the rotation of the fixed tube 121 can be adjusted manually or driven by a corresponding drive mechanism (e.g., a stepper motor drives the rotation of the fixed tube 121 through a reducer). In this case, the drive mechanism can be controlled by a controller to control the degree of rotation of the fixed tube 121.

[0050] like Figure 5 As shown, the fragrance mechanism 12 also includes a force-applying member 123 and abutting member 124. The outer diameters of both the abutting member 124 and the force-applying member 123 are larger than the outer diameter of the fragrance stick 122 and smaller than or equal to the inner diameter of the mounting cavity 1111. Both the force-applying member 123 and the abutting member 124 may be provided with insertion slots. The two ends of the fragrance stick 122 are respectively inserted into the two insertion slots, thereby fixing the force-applying member 123 and the abutting member 124 to the fragrance stick 122. The fixing tube 121 has a replacement port communicating with the fixing cavity 1211. The fragrance mechanism 12 is inserted into the fixing cavity 1211 through the replacement port. The abutting member 124 abuts against the inner wall of the fixing cavity 1211. The fragrance stick 122 is located in the fixing cavity 1211. Part of the force-applying member 123 is located in the fixing cavity 1211 and abuts against the cavity wall of the fixing cavity 1211. The other part of the force-applying member 123 extends out from the replacement port. In this way, the fragrance stick 122 can be removed by holding the force-applying component 123, thereby realizing the replacement of the fragrance stick 122.

[0051] Optionally, the number of mounting tubes 112 can be 3, 4, 5, 6, 7, 8, 9, 10 or more.

[0052] According to a second aspect of this application, an air conditioning system is provided, which includes an air conditioner and the aforementioned fragrance device. The air conditioner is connected to a connecting body 2 so that the air outlet 6 of the air conditioner is connected to the first end of the fragrance channel 21. The air conditioner has the same technical effect as the aforementioned fragrance device, which will not be described in detail here.

[0053] Optionally, the end of the transition channel 22 away from the fragrance channel 21 can directly vent air, or the air can be vented through the air outlet 7. When the air conditioning system includes the air outlet 7, the air outlet 7 is connected to the end of the transition channel 22 away from the fragrance channel 21, so that the gas can flow to the passenger compartment through the air outlet 7.

[0054] Optionally, the connecting body 2 can be equipped with flanges, clips, or other structures to connect the connecting body 2 with the air outlet 7 and the air outlet 6 of the air conditioner.

[0055] According to a third aspect of this application, a vehicle is provided, which includes the aforementioned air conditioning system and has the same technical effects as the aforementioned air conditioning system, which will not be described in detail here.

[0056] Alternatively, the vehicle may be a car, a flying car, or other manned vehicle.

[0057] During the installation of the fragrance device, firstly, the connecting body 2 is connected to the air outlet 7 and the air outlet 6 of the air conditioner. Then, based on the usage requirements, the fragrance module 1 is arranged in a suitable position. Next, a flexible tube 3 of appropriate length is selected. The two ends of one flexible tube 3 are connected to the first mounting connector 5 and the outlet 27, respectively, and the two ends of the other flexible tube 3 are connected to the second mounting connector 5 and the inlet 28, respectively. Then, the required fragrance mechanism 12 is installed into the corresponding mounting tube 112. The fixing tube 121 is rotated to adjust the fragrance intensity. When air is discharged from the air outlet 6 of the air conditioner, the gas can flow through the outlet 27 to the first connection port 114, and then return to the fragrance channel 21 through the connecting channel 1121, the second connection port 115, and the inlet 28. When the gas flows through the connecting channel 1121, the gas can carry the fragrance molecules in the fragrance mechanism 12, so that the gas carrying the fragrance molecules can flow to the passenger compartment through the transition channel 22 and the air outlet 7.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model 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 therein.
