Description

Technical Field

[0001] This utility model relates to the technical field of odor elimination, and in particular to a spray structure and an odor control system. Background Technology

[0002] Existing odor control systems can be made into fragrance diffusers, aroma diffusers, etc. They generally include an atomizer, an atomizing core, and an air pump. The air pump delivers high-pressure gas to the atomizing core, and the atomizing part of the atomizing core atomizes the liquid in the atomizer into particulate spray. The particulate spray diffuses into the surrounding environment through the spray nozzle. Disinfectants, bactericides, fragrance enhancers or essential oils can be added to the liquid.

[0003] The power of the air pump is closely related to the diffusion range and utilization efficiency of the particulate spray. Using a high-power air pump will cause the liquid in the atomizer to be consumed quickly, resulting in a shorter continuous use time and reduced practicality of the diffuser. Conversely, using a low-power air pump will allow the liquid in the atomizer to be used for a longer time, but the particulate spray from the nozzle will be weaker, with a limited diffusion distance. Furthermore, the particulate spray tends to adhere to the outer surface of the diffuser, resulting in essential oil residue on the surface after prolonged use. Utility Model Content

[0004] The purpose of this invention is to improve the existing odor control system, which has a limited diffusion distance and is prone to being covered with essential oil after prolonged use. This invention provides a spray structure and an odor control system.

[0005] The technical solutions for achieving the above objectives include the following:

[0006] An odor control system includes: an air outlet cover, an atomizing cover, and a fan. The air outlet cover is fitted over the atomizing cover, and an air outlet channel is formed between the inner wall of the air outlet cover and the outer wall of the atomizing cover. The air outlet cover has an air outlet, which is connected to one end of the air outlet channel, and the other end of the air outlet channel is connected to the air outlet of the fan. The atomizing cover has a spray nozzle, and the air outlet is positioned close to the spray nozzle.

[0007] The air outlet cover has a first side and a second side, the spray nozzle is located between the first side and the second side, and the air outlet is disposed on the first side.

[0008] In one embodiment, the air outlet cover includes a support body, a baffle, and at least two air guide plates, wherein the support body is sleeved outside the atomizing cover;

[0009] On the first side, both ends of each of the air guide plates are installed on the inner wall of the supporting body, and an air outlet is formed between the two air guide plates;

[0010] On the second side, both ends of the baffle are installed on the inner wall of the support body, and the gap between the support body and the atomizing cover is sealed by the baffle.

[0011] In one embodiment, the air guide plate has multiple pieces, which are spaced apart on a first side and a second side.

[0012] The second side has an air outlet, and the air outlet is sealed by a baffle.

[0013] In one embodiment, the air guide plate is inclined, the air outlet direction intersects the spray direction of the spray nozzle, and an angle is formed between the air outlet direction and the spray nozzle direction.

[0014] In one embodiment, the included angle is greater than or equal to 45 degrees.

[0015] In one embodiment, the atomizing cap further has a spray channel that communicates with a spray nozzle; the spray channel is separated from the air outlet channel, and the air outlet channel is annular and surrounds the spray channel.

[0016] This utility model also proposes an odor control system, including a shell, an atomizer, an air pipe, an air pump, and a spray structure as described above. The atomizer, air pipe, air pump, and fan are all installed inside the shell. The atomizer is connected to the air pump through the air pipe. The atomizing cover is installed on the atomizer, and the air outlet cover is installed on the shell.

[0017] The airflow velocity at the spray nozzle is less than the airflow velocity at the air outlet.

[0018] In one embodiment, the outer surface of the housing is recessed inward to form a groove, the groove having a through hole that passes through the outer surface of the housing from the inside.

[0019] The outer casing has a first sidewall and a second sidewall; the first sidewall has a first slot and the second sidewall has a second slot, and both the first slot and the second slot are connected to the wire groove.

[0020] The first sidewall and the second sidewall are arranged adjacent to each other, and / or the first sidewall and the second sidewall are arranged opposite to each other.

[0021] In one embodiment, the wire groove includes a first receiving groove and a second receiving groove, the first receiving groove and the second receiving groove are respectively located on both sides of the wire hole, the first receiving groove is connected to a first slot opening, and the second receiving groove is connected to a second slot opening.

[0022] In one embodiment, the groove is positioned near the top corner of the housing.

[0023] The technical solution provided by this utility model has the following advantages and effects:

[0024] The air outlet cover has a first side and a second side, with the spray nozzle located between the first and second sides. The air outlet is positioned on the first side, thus the second side is sealed. This reduces the area of ​​the air outlet on the air outlet cover. When the air outlet is smaller, the gas flow rate decreases, but the velocity increases, further accelerating the gas flow near the spray nozzle. Moreover, since the air outlet is located on the first side, when the airflow from the air outlet acts on the area above the spray nozzle, the gas velocity above the spray nozzle increases, creating a certain negative pressure in the area above the spray nozzle. Due to this negative pressure, the particulate spray from the spray nozzle approaches the area above the spray nozzle, causing the airflow from the air outlet to act on the particulate spray, preventing it from falling downwards and further improving the diffusion effect of the particulate spray. It also prevents the particulate spray from falling onto the outer surface of the odor control system. Attached Figure Description

[0040] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.

[0041] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0042] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the related listed items.

[0043] It should be noted that when a component is considered "fixed" to another component, it can be directly fixed to the other component or there can be an intervening component; when a component is considered "connected" to another component, it can be directly connected to the other component or there can be an intervening component; when a component is considered "mounted" on another component, it can be directly mounted on the other component or there can be an intervening component; when a component is considered "placed" on another component, it can be directly placed on the other component or there can be an intervening component.

[0044] This utility model proposes a spray structure, such as Figures 1 to 5As shown, the device includes an air outlet cover 61, an atomizing cover 32, and a fan 62. The air outlet cover 61 is fitted over the atomizing cover 32, and an air outlet channel 63 is formed between the inner wall of the air outlet cover 61 and the outer wall of the atomizing cover 32. The air outlet cover 61 has an air outlet 611, which is connected to one end of the air outlet channel 63, and the other end of the air outlet channel 63 is connected to the air outlet of the fan 62. The atomizing cover 32 has a spray nozzle 31, and the air outlet 611 is located close to the spray nozzle 31. The air outlet cover 61 has a first side 601 and a second side 602, with the spray nozzle 31 located between the first side 601 and the second side 602, and the air outlet 611 located on the first side 601.

[0045] Specifically, when the atomizing cap 32 sprays particulate mist from the spray nozzle 31, the fan 62 is activated. The gas blown by the fan 62 is blown towards the air outlet 611 through the air outlet channel 63. Since the air outlet 611 is close to the spray nozzle 31, the airflow from the air outlet 611 acts on the spray nozzle 31, accelerating the gas flow rate near the spray nozzle 31, providing power for the flow of particulate mist, making the particulate mist travel a longer distance, and increasing the diffusion range of the particulate mist.

[0046] Furthermore, the air outlet cover 61 has a first side portion 601 and a second side portion 602. The spray nozzle 31 is located between the first side portion 601 and the second side portion 602. The air outlet 611 is disposed on the first side portion 601. Therefore, the second side portion 602 is in a sealed state. This reduces the area of ​​the air outlet 611 on the air outlet cover 61. When the air outlet 611 is reduced, the gas flow rate of the air outlet 611 decreases and the speed increases, further accelerating the gas flow rate near the spray nozzle 31. Furthermore, the air outlet 611 is located on the first side 601. When the airflow from the air outlet 611 acts on the area above the spray nozzle 31, the gas velocity above the spray nozzle 31 increases, and a certain negative pressure is generated in the area above the spray nozzle 31 where the air outlet 611 acts. The particulate spray from the spray nozzle 31 will approach the area above the spray nozzle 31 due to the negative pressure, so that the airflow from the air outlet 611 acts on the particulate spray, preventing the particulate spray from falling downwards, further improving the diffusion effect of the particulate spray, and also preventing the particulate spray from falling onto the outer surface of the odor control system 100.

[0047] In some embodiments, the air outlet cover 61 includes a support body 615, a baffle 613, and at least two air guide plates 612. The support body 615 is fitted over the atomizing cover 32. On the first side 601, both ends of each air guide plate 612 are mounted on the inner wall of the support body 615, forming an air outlet 611 between the two air guide plates 612. Specifically, the support body 615 is fitted over the atomizing cover 32. On the first side 601 and the second side 602, there is a ventilation gap between the support body 615 and the atomizing cover 32. On the first side 601, the air guide plate 612 is used to guide the air outlet 611 in a direction 614, giving the air outlet 611 a strong directional characteristic. On the second side 602, both ends of the baffle 613 are mounted on the inner wall of the support body 615, and the gap between the support body 615 and the atomizing cover 32 is sealed by the baffle 613. On the second side 602, the baffle 613 seals the ventilation gap on the second side 602, so that the first side 601 has an air outlet 611, further reducing the air flow of the air outlet 611 on the air outlet cover 61.

[0048] In some embodiments, the air guide plate 612 comprises multiple plates, which are spaced apart on the first side 601 and the second side 602. On the first side 601, an air outlet 611 is formed between two adjacent air guide plates 612. On the second side 602, the air outlet 611 between two adjacent air guide plates 612 is sealed by a baffle 613. Specifically, when producing the spray structure, some fans 62 have higher power and require air outlets 611 to be opened on both the first side 601 and the second side 602 to increase the air outlet area; while some fans 62 have lower power and only need to have air outlets 611 on either the first side 601 or the second side 602. Therefore, by using the same mold to produce a spray structure with air outlets 611 on both the first side 601 and the second side 602, and then sealing the air outlet 611 of the second side 602 with a baffle 613, the utilization efficiency of the mold can be improved.

[0049] Preferably, the air guide plate 612 is inclined, and the air outlet 611's air outlet direction 614 intersects with the spray direction 33 of the spray nozzle 31, forming an angle 34 between them. Specifically, the air guide plate 612 is inclined and guides the air outlet 611's air outlet direction 614 so that it faces upwards towards the spray nozzle 31; while the air outlet 611's air outlet direction 614 intersects with the spray direction 33 of the spray nozzle 31, so that the air outlet 611 directly acts on the spray direction 33 of the spray nozzle 31, accelerating the diffusion of the particulate spray in the spray direction 33 and further increasing the diffusion distance of the particulate spray.

[0050] Preferably, the included angle 34 is greater than or equal to 45 degrees. Specifically, testing has shown that setting the included angle 34 to be greater than 45 degrees allows the airflow from the outlet 611 to act on the area near the lower part of the spray nozzle 31. When the particulate spray flows out of the spray nozzle 31, the particulate spray can be immediately carried and diffused by the airflow from the outlet 611, resulting in a more significant diffusion effect. If the included angle 34 is less than 45 degrees, the airflow from the outlet 611 will act on the area above the spray nozzle 31, with a longer effective distance and a weaker effect.

[0051] Preferably, the atomizing cap 32 also has a spray channel 35, which is connected to the spray nozzle 31. The spray channel 35 is separated from the air outlet channel 63, which is annular and surrounds the spray channel 35. Specifically, in the atomizer 3, the atomizing core atomizes the liquid into particles. The particles enter the spray channel 35 and are then ejected from the spray nozzle 31. This separates the spray channel 35 from the air outlet channel 63, preventing the airflow from the air outlet channel 63 from acting on the spray channel 35. Large particles have weak atomizing power and limited flow distance, thus preventing large particles in the spray channel 35 from being ejected from the spray nozzle 31 and saving liquid.

[0052] like Figures 1 to 8 As shown, this utility model also proposes an odor control system 100, including a housing 1, an atomizer 3, an air pipe 5, an air pump 4, and a spray structure as described above. The atomizer 3, air pipe 5, air pump 4, and fan 62 are all installed inside the housing 1. The atomizer 3 is connected to the air pump 4 through the air pipe 5. An atomizing cover 32 is installed on the atomizer 3, and an air outlet cover 61 is installed on the housing 1. The airflow velocity at the spray nozzle 31 is less than the airflow velocity at the air outlet 611. Specifically, after the air pump 4 is electrically activated, it generates high-pressure gas. The high-pressure gas is delivered to the atomizing core of the atomizer 3 through the air pipe 5. The atomizing position of the atomizing core draws liquid from the atomizing bottle and atomizes the liquid into particulate spray. The particulate spray flows into the spray nozzle 31 from the spray channel 35 and is then sprayed out. The fan 62 is activated, and the accelerating airflow generated by the fan 62 acts on the air outlet 611, accelerating the particulate spray at the spray nozzle 31. The airflow velocity at the spray nozzle 31 is less than that at the air outlet 611. When the airflow from the air outlet 611 acts on the area above the spray nozzle 31, a pressure difference is generated between the airflow above the spray nozzle 31 and the airflow blown from the air outlet 611 towards the area above the spray nozzle 31. This pressure difference causes the particulate spray from the spray nozzle 31 to move toward the airflow from the air outlet 611, preventing the particulate spray from falling downwards.

[0053] In some embodiments, the outer surface of the housing 1 is recessed inward to form a wire groove 11, and the wire groove 11 has a wire hole 14 that passes through the outer surface of the housing 1 from the inner side of the housing 1. The housing 1 has a first sidewall 101 and a second sidewall 102. The first sidewall 101 has a first slot 12 and the second sidewall 102 has a second slot 13. Both the first slot 12 and the second slot 13 are connected to the wire groove 11. The first sidewall 101 and the second sidewall 102 are arranged adjacent to each other, and / or the first sidewall 101 and the second sidewall 102 are arranged opposite to each other.

[0054] Specifically, the outer casing 1 has a wire groove 11. When one end of the wire 2 has a connector, this connector is used to insert into the wire groove 11. The outer wall of the connector is lower than the outer surface of the outer casing 1, so that the connector is hidden in the wire groove 11. The other end of the wire 2 passes through the first slot 12 or the second slot 13. When the socket is close to the first side wall 101, the other end of the wire 2 passes through the first slot 12 and connects to the socket. When the socket is close to the second side wall 102, the other end of the wire 2 passes through the second slot 13 and connects to the socket. In this embodiment, the first sidewall 101 and the second sidewall 102 are adjacent, and the first slot 12 or the second slot 13, which is adapted to their distance, is selected to guide the wire 2. The first sidewall 101 and the second sidewall 102 are arranged opposite each other, and the difference between selecting the first slot 12 or the second slot 13 to guide the wire 2 is relatively large. In this way, the insertion method of the wire 2 can be adjusted according to the installation position of the socket, avoiding the wire 2 from being tangled or crossed, improving the utilization rate of the wire 2, and solving the problem that the wiring method of the existing odor control system 100 requires the wire 2 to have sufficient length and the wiring is messy and tangled.

[0055] Preferably, the wire trough 11 includes a first receiving groove 111 and a second receiving groove 112, which are located on both sides of the wire hole 14. The first receiving groove 111 communicates with the first slot 12, and the second receiving groove 112 communicates with the second slot 13. Specifically, when the connector of the wire 2 is inserted into the wire trough 11 through the first slot 12, the connector is accommodated in the first receiving groove 111. When the connector of the wire 2 is inserted into the wire trough 11 through the second slot 13, the connector is accommodated in the second receiving groove 112. Therefore, the connector of the wire 2 can be accommodated in the wire trough 11 regardless of whether it is inserted through the first slot 12 or the second slot 13.

[0056] Preferably, the wire groove 11 is positioned near the top corner of the outer casing 1. Specifically, this allows the wire groove 11 to be positioned near the edge of the outer casing 1, reducing the length of the first groove 12 and the second groove 13, and reducing the distance between the first groove 12 or the second groove 13 and the wire groove 11.

[0057] Preferably, the outer casing 1 has a first surface 103 and a second surface 104. A first sidewall 101 and a second sidewall 102 are both disposed between the first surface 103 and the second surface 104. The two ends of the first sidewall 101 are connected to the first surface 103 and the second surface 104, respectively, and the two ends of the second sidewall 102 are also connected to the first surface 103 and the second surface 104, respectively. The first surface 103 and the second surface 104 are arranged opposite to each other. The first surface 103 has an operation panel 1031, and a wire trough 11 is located on the second surface 104. Specifically, the outer casing 1 has a first surface 103 and a second surface 104. The first surface 103 has an operation panel 1031 for controlling the odor control system 100, while the wire trough 11 is disposed on the second surface 104. The first surface 103 and the second surface 104 are arranged opposite to each other. When the outer casing 1 is hung on a wall, the second surface 104 is flush with the wall, and the wire trough 11 is hidden, allowing the connector of the wire 2 to be installed in a concealed manner.
