Description

Technical Field

[0001] This invention generally relates to insect repellent devices. Specifically, this invention relates to an insect repellent device that is linkable to other insect repellent devices and control units to regulate the release of volatile substances, thereby controlling insects within a defined area and / or creating a comfortable outdoor environment. Background Technology

[0002] Outdoor spaces offer attractive places for people to gather, dine, and relax. However, these spaces also attract insects and other pests that can hinder effective use of the area and, particularly in commercial environments, create an unfavorable environment, reducing revenue and negatively impacting the facility's reputation. Standalone insect repellent devices are known and create defined areas protected from pests. These devices work well, but are designed to operate independently and do not effectively utilize volatile substances, increasing costs. Known devices can be linked to power heating elements, but their operation cannot be adjusted in response to environmental conditions or system performance levels.

[0003] The inability of insect repellent devices to communicate and coordinate their operational status, adjust output parameters based on local conditions, and adapt to different materials and outputs to provide different environmental effects (e.g., odor regulation, lighting control, and audio output) hinders the ability to conveniently and effectively control outdoor environments for pest control or atmosphere creation. Furthermore, outdoor environments offer unfavorable conditions such as rain, wind, and temperature variations, which reduce the effective use of volatile materials. Therefore, it is desirable to provide an outdoor environmental control system that provides the ability to reduce pest presence, provide a pleasant sensory atmosphere, and resist negative environmental factors affecting device operation. Summary of the Invention

[0004] This invention generally relates to insect repellent devices. In particular, the invention relates to an insect repellent device that can be linked to other insect repellent devices and a control unit to control insects within a defined area. The insect repellent station can operate as a single unit or as a series of stations placed in a selected area. In one embodiment, one or more insect repellent stations are powered and operated by a separate hub controller. The insect repellent stations can also be powered individually, for example, by solar energy, batteries, or a plug-in power source. The hub controller can be a single unit or can be integrated into one or more insect repellent stations. The hub controller operates one or more insect repellents to disperse repellent material and can determine the duration of repellent material dispersion based on one or more inputs.

[0005] In one embodiment, the insect repellent station includes: a housing defining a volume; a heater assembly disposed within the volume, the heater assembly including a heater housing and a heating element having an orifice; a fluid reservoir supported by the heater assembly and containing a volatile insect repellent fluid and a core extending from the volatile insect repellent fluid into the orifice, the core dispersing the volatile insect repellent fluid; an IR window mounted within the heater housing; and a time-of-flight (ToF) sensor mounted adjacent to the IR window within the heater housing.

[0006] In another embodiment, the insect repellent system includes a hub controller having a hub controller body that communicates with at least one insect repellent station and is configured to provide at least one of input power to the at least one insect repellent station or to provide a command signal for controlling a heating element within the at least one insect repellent station and the output of a volatile insect repellent fluid for the at least one insect repellent station. The hub controller includes a power button assembly mounted within the hub controller body.

[0007] In another embodiment, the insect repellent system includes a hub controller having a hub controller body that communicates with at least one insect repellent station and is configured to provide at least one of input power to the at least one insect repellent station or to provide a command signal for controlling a heating element within the at least one insect repellent station and the output of a volatile insect repellent fluid for the at least one insect repellent station. The hub controller body includes a recess defining space for a cable and includes a removably attached mounting plate. A lower surface of the hub controller body includes a mounting tab defining a mounting slot, wherein the mounting plate is configured to be removably attached to a mounting surface such that when the mounting plate is attached to the mounting surface, the hub controller body slides onto the mounting plate, such that a portion of the mounting plate inserts into and locks into the slot, and wherein the hub controller includes a power input module (PEM) within the recess for connection to a power source.

[0008] In a further embodiment, the insect repellent station includes a housing defining a volume. A heater assembly is disposed within this volume and includes a heater housing and a heating element having a generally cylindrical heater portion defining a heater orifice. A fluid reservoir bottle is supported by the heater assembly and contains volatile insect repellent fluid and a core extending from the volatile insect repellent fluid into the heater orifice, wherein the core dissipates the volatile insect repellent fluid. A recovery shield is configured to reduce condensate collection.

[0009] In another embodiment, the ground stake for the insect repellent station includes a stake body and a mounting flange having three elongated blades defining a Y-shaped cross-section, wherein a cavity is centrally formed in the mounting flange and the upper portion of the stake body.

[0046] Now referring to the attached diagram, in Figure 1 , 2A Embodiments of a linked insect repellent system, generally designated 10, are shown in Figures 2B and 2B. The illustrated linked insect repellent system 10 has at least one emitter or insect repellent station 12 and a hub controller 14. In other embodiments of the linked insect repellent system 10, the hub controller 14 may be integrated into the insect repellent station 12. The insect repellent stations 12 may be connected in series, parallel, or a combination thereof. For example, in… Figure 1 and 2A In the embodiment of the insect repellent system 10 shown, multiple insect repellent stations 12 are connected in series or daisy-chain to form an area preventing insect intrusion. Figure 2B In the embodiment of the insect repellent system 10 shown, multiple insect repellent stations 12 are connected together in parallel. As shown in the embodiment, the insect repellent stations 12 are connected together and connected to a hub controller 14 to provide power and, in some embodiments, control communication.

[0047] Hub controller 14 can be connected to a power source, such as a fixed base power supply in a building or home (typically 110 / 120 volts in the United States) or an environmentally generated power source (such as a solar panel or wind turbine), or have battery power. Hub controller 14 may include a step-down transformer or other device to provide a lower voltage output to insect repellent station 12 when the input power exceeds the power requirements of insect repellent station 12. Hub controller 14 may also include an AC-to-DC converter to provide a DC output from an AC input.

[0048] In one embodiment, the hub controller 14 can be connected to a higher voltage power source ranging from 110 to 120 volts AC and can generate one of a 12-volt, 24-volt, 36-volt, or 48-volt DC output to power each of the insect repellent stations 12. Any desired combination of input and output voltages is within the scope of this invention. In some embodiments, the insect repellent system 10 can be powered by individual insect repellent stations 12 via batteries. In other arrangements, the insect repellent stations 12 (individually or as a connected group) can be coupled to solar cell power elements. The hub controller 14 can send one or more control signals to each of the insect repellent stations 12 to control the dispersal of insect repellent material at each station, as will be described in detail below. The hub controller 14 and / or the insect repellent stations 12 can be connected via wired and / or wireless devices.

[0049] like Figure 3 and 4 As best shown, the insect repellent station 12 includes a housing comprising an upper section 16 and a lower section 18. In such a manner... Figure 5 and6 In the illustrated embodiment, the upper segment 16 includes a cylindrical insulating sleeve 16A located within a cylindrical shield 16B, defining an internal space 19. The cap assembly 20 includes a base 20A, a recyclable shield 20B, and a cap 20C. The base 20A includes a downwardly sloping surface terminating at a centrally formed opening 23, the purpose of which will be described below. Figure 9A As best shown, the recycling shield 20B includes a plurality of radially extending openings 21 formed therethrough.

[0050] The cap assembly 20 is attached to the first end of the upper section 16 (when observed). Figure 5 and 6 (At the upper end). In the illustrated embodiment, the insulating sleeve 16A is connected to the lower section 18 via a snap-fit ​​connection. Similarly, the cap assembly 20 is connected to the upper section 16 via a snap-fit ​​connection. Optionally, the connection between the insulating sleeve 16A and the lower section 18, and the connection between the cap assembly 20 and the upper section 16, can be achieved in any desired manner, including but not limited to bayonet connectors, threaded connections, and pin and stop connection structures.

[0051] The inner shield 16A and outer shield 16B provide protection for the various components of the insect repellent station 12 through the internal space 19. For example, the fluid storage bottle 22 (in...) Figure 5 (Not shown in the diagram so as to make a clearer view of the structure of the insect repellent station 12) and the heater assembly 24 are installed in the interior space 19 of the upper section 16, both of which will be described in detail below.

[0052] Reference Figures 10 to 14 An embodiment of a fluid reservoir bottle, generally shown as 22, is illustrated and configured for use with an insect repellent station 12. Fluid reservoir bottle 22 includes a refill bottle 26 defining a fluid reservoir 28, a reservoir cap 30, and a lid or cap 32. Fluid reservoir 28 contains insect repellent fluid (not shown) and a core 29 immersed in the insect repellent fluid and extending longitudinally from the refill bottle 26.

[0053] The fluid reservoir 28 is shown with a generally bowl-shaped lower end 34 having two opposing planes 36. However, it should be understood that the fluid reservoir 28 can have other geometries, such as spherical, cylindrical, ellipsoidal, square, rectangular, triangular, or any polyhedral or smooth geometry. The reservoir cover 32 includes a core port 38 through which a core 29 extends. The core 29 has a clearance fit with the core port 38, as well as... Figure 14As shown, air is allowed to enter the fluid reservoir 28 for venting purposes. The reservoir cap 32 may be formed of transparent plastic, including but not limited to PETG, PCTG, PET, or other materials compatible with the insect repellent formulation, and includes a reservoir neck or mounting cover 40 having an external attachment structure for connection to the cap 30, for maintaining the integrity of the insect repellent fluid within the core 29 and the fluid reservoir 28 during handling and transportation.

[0054] In the illustrated embodiment, the external attachment structure is shown as a threaded attachment 42. Alternatively, other attachment methods, such as snap-fit, barbs, interference fits, etc., can be used to retain the reservoir cap 30 on the refill bottle 26. Figure 9 As best shown, the mounting cover 40 is configured with two opposing mounting legs 40A and 40B. Alternatively, in another embodiment (not shown), the reservoir cover 32 may be formed without the mounting cover 40, but instead includes a magnet or metal target element, such as a gasket surrounding the core port 38, wherein the heater assembly 24 may carry another of the magnet or metal target element as an optional mounting configuration. Figures 11 to 13 As shown, float 48 includes a central mounting hole 49 and is located within fluid reservoir 28. As will be described in detail below, float 48 is formed of a buoyant material such that it will float on the surface of the liquid insect repellent fluid (not shown) therein.

[0055] Although not shown, a fluid seal, such as an O-ring, may be provided between the inner surfaces of the core 29 and the core port 38 if required.

[0056] Each leg 40A and 40B of the mounting cover 40 has an opening or detent 44 formed therein. The detent 44 is configured to engage a corresponding attachment boss 46 on the heater assembly 24 to retain the fluid reservoir bottle 22 to the heater assembly 24. In the illustrated embodiment, the detent 44 in the mounting cover 40 engages the attachment boss 46 in a snap-fit ​​engagement manner. Alternatively, the attachment boss 46 may be formed on the mounting cover 40 and extend into the detent 44 formed in the heater assembly 24. The mounting cover 40 also provides alignment of the core 29 with the center of the heater assembly 24.

[0057] The refill bottle 26 may include an RFID tag (not shown) attached to its lower surface. The RFID tag may be secured or otherwise attached to the refill bottle 26 in any desired manner, including but not limited to adhesives and fasteners. The RFID tag may also be incorporated into a label attached to the refill bottle 26, or it may be molded into the refill bottle 26 and completely encased in plastic to prevent user access and tampering.

[0058] It should be understood that the fluid reservoir 28 can be configured to hold any desired amount of insect repellent fluid based on the user's needs. For example, the fluid reservoir 28 can be configured to hold sufficient insect repellent fluid for extended operation, such as during the insect control season. The insect control season can range from 1 to 2 months, 3 to 4 months, 6 months, or more, depending on the region of the country or the application.

[0059] like Figure 7 As shown, heater assembly 24 is mounted on support arm 50 within upper section 16 and suspended at the center of internal space 19 therein. In the illustrated embodiment, heater assembly 24 is positioned toward the upper portion of upper section 16 to facilitate a chimney effect in internal space 19 of upper section 16, thereby establishing a natural convection flow pattern. Support arm 50 includes conduit channel 52 to allow electrical connection between hub controller 14 and heater 26. Support arm 50 is mounted to lower section cover assembly 98 of lower section 18. However, support arm 50 may be attached to or integrally formed with upper section 16 or lower section 18. As will be explained below, support arm 50 and / or heater assembly 24 may include fluid height sensing structures to determine the actual fluid height of the insect repellent fluid when insect repellent station 12 is used.

[0060] exist Figure 6 , 7 The heater assembly 24, best shown in Figure 31, includes a heater housing assembly 25 having a first portion or heater cover 56 and a second portion or heater housing 58, wherein the heater cover 56 and the heater housing 58 are attached by a snap-fit ​​connection structure. A heater PCBA 60 is mounted within the heater cover 56. The lower surface of the heater cover 56 shown includes a partially conical heater funnel 62.

[0061] The heater cover 56 and heater housing 58 are formed of any desired rigid, heat-resistant plastic, including but not limited to glass-filled nylon and other heat-resistant plastic materials. Figure 5 and 8 As best shown, the partially conical heater funnel 62 advantageously directs air within the insect repellent station 12 toward and into the heater orifice or hole 68, as indicated by arrow A1.

[0062] The heater assembly 24 includes a heating element 64 having a generally cylindrical heater portion 66 defining a heater aperture 68 and electrically connected to a heater PCBA 60 via an electrical connector 70. A cylindrical resilient heater gasket or seal 72 (e.g., an O-ring) is mounted between the heater cover 56 and the lower outer surface of the cylindrical heater portion 66. The heater assembly 24 may be ceramic-based and configured as a heater controlled by a negative temperature coefficient (NTC) or positive temperature coefficient (PTC) thermistor. Alternatively, other types of heaters and heater assemblies may be used.

[0063] The heater extension member 74 is mounted around the upper end of the cylindrical heater portion 66. For example... Figure 6 , 7 As best shown in 17, the heater extension member 74 includes a cylindrical portion 76 attached around the upper end of the cylindrical heater portion 66 and a collection portion 78 defining a cylindrical groove 80. A cylindrical resilient heater gasket or seal 82 is mounted between the base 20A of the cap assembly 20 and the heater housing 58 and circumferentially surrounds the heater extension member 74.

[0064] like Figure 6 As shown, an IR window 84 is formed in the lower surface of the heater cover 56. The IR window 84 may be surrounded by a seal (not shown). A time-of-flight (ToF) sensor 86 is mounted to the heater PCBA 60 adjacent to the altitude sensing window 84 (when observing). Figure 6 (At that time, above IR window 84).

[0065] The ToF sensor 86 can be any desired ToF sensor, such as the ToF sensor manufactured by STMicroelectronics. The ToF sensor 86 allows for both raw counts and millimeter-level distance output.

[0066] The IR window 84 can be tuned to eliminate the influence of light from other wavelengths. An anti-reflective coating can be provided on the surface of the IR window 84 to reduce crosstalk between the IR window 84 and the reservoir cap 30. The seal around the IR window 84 reduces dirt, dust, and debris that could block the emitter signal of the ToF sensor 86. The IR window 84 must be transparent to the wavelength of the ToF sensor 86 emitter. Advantageously, the IR window 84 can be tuned to eliminate the influence of light from other wavelengths, including ambient light. Although only a portion of the reservoir cap 30 adjacent to the IR window 84 needs to be formed of transparent PETG, the entire reservoir cap 30 can be formed of transparent PETG that is transparent to the wavelength of the ToF sensor 86 emitter if desired. Advantageously, PETG has strong chemical resistance.

[0067] If desired, one or more portions of the memory cap 30 adjacent to the IR window 84 can be formed of a relatively thin transparent PETB. The relatively thin portion of the memory cap 30 reduces the angle at which light can return to the interior of the ToF sensor 86 and has a positive effect on reducing crosstalk in the ToF sensor 86.

[0068] Float 48 serves as a target surface for the ToF sensor 86. Float 48 provides a stronger and more robust signal than that from the liquid surface of the insect repellent fluid. Float 48 also provides helpful visual assistance to the user of the insect repellent station 12. The color of float 48 can match the characteristics of the fluid reservoir bottle 22 and can be used to identify the type, size, and / or brand of the fluid reservoir bottle 22. Float 48 can be formed from closed-cell foam. Alternatively, float 48 can be formed from any desired material that is chemically compatible with the insect repellent fluid in the fluid reservoir bottle 22 and moves with the surface of the insect repellent fluid. Float 48 can be provided with a reflective surface. The reflective properties of the reflective surface and the color selection of float 48 can both alter the reflected signal intensity of float 48. Float 48 can have any desired size. As shown, core 29 acts as a landmark.

[0069] The ToF sensor 86 allows for active monitoring of the repellent fluid level in the refill bottle 26. This capability eliminates the need to estimate the refill height and takes into account external factors that could cause the repellent fluid to be released from the refill bottle 26. The use of the ToF sensor 86 will also allow the repellent station 12 to determine the presence of the fluid reservoir bottle 22 and whether the fluid reservoir bottle 22 is empty. The use of the ToF sensor 86 will further provide the linked repellent system 10 with the ability to warn the user that the fluid reservoir bottle 22 is absent, not properly installed, or positioned at an undesirable angle, and that the performance of the repellent station 12 may therefore be degraded.

[0070] The ToF sensor 86 works best when measuring the distance between itself and a solid object. In theory, ToF technology (such as the ToF sensor 86) could be used to sense the height of the insect repellent formulation in the refill bottle 26 without the need for the float 48; however, including the float 48 increases the reliability of fluid height measurement.

[0071] Directly sensing fluid height without using a float is difficult because the specular properties of the fluid surface are correlated with the fluid's clarity. It has been shown that the properties of the formulation used in the insect repellent station 12 negatively impact the ability of the ToF sensor 86 to provide distance data as it is designed to.

[0072] The shield 16B can be made of any suitable material, although the material selection and component design are taken into account heat transfer considerations.

[0073] In an alternative embodiment of the repellent station 12, reporting of the fluid level in the refill bottle 26 is accomplished via a hub controller 14. The hub controller 14 can be configured to maintain a log of when one or more of the multiple repellent stations 12 are turned on and operated. At a nominal release rate of approximately 220 mg / hr, the hub controller 14 can calculate an estimate of the amount of repellent formulation released over the time elapsed since the last fluid level update. The hub controller 14 then subtracts the calculated amount of repellent formulation released from the total remaining repellent formulation, displaying the result to the user as a percentage of the total repellent formulation fill. The fluid repellent formulation level is then reported to the user, for example, in a graphical display on a mobile device.

[0074] In one embodiment, the shield 16B may be made of plastic or polymer materials (including, but not limited to, 20% glass-filled polyphenylene oxide (PPE)-based materials, glass-filled polypropylene, glass-filled nylon, and non-glass-filled polymers) that insulate the internal volume of the shield from environmental heat loads (such as sunlight or ambient heat loads (dryer ventilation, structural thermal radiation, etc.) and heat sources (such as wind, water, shade, etc.) and slow the release of heat generated by the heating element from the internal volume. In some embodiments, it may be desirable to construct the shield 16B from a metallic material, particularly for safety and durability. Figure 5 , Figure 6 and Figure 8 As shown, the insulating sleeve 16A is disposed inside the cover 16B (on the inner wall of the cover 16B, against the inner wall of the cover 16B, or spaced apart from the inner wall of the cover 16B), although the cover 16B may be disposed on the outer surface of the cover 16B, against the outer surface of the cover 16B, or outside the outer surface of the cover 16B. In the illustrated embodiment, the cover 16B is mounted to the insulating sleeve 16A via a threaded connection. The insulating sleeve 16A includes a plurality of bevels 92 configured to engage a plurality of corresponding pins or lugs 94 on the upper outer surface of the lower section 18. The insulating sleeve 16A may also be connected to the lower section 18 in any desired manner, such as by press fit, snap fit, or threaded connection.

[0075] Typically, the material selection for the components of the insect repellent station 12 takes into account the heat transfer between the insect repellent station 12 and the evaporating insect repellent fluid. Components of the insect repellent station 12 subjected to vapor contact can be selected from materials with relatively high specific heat and therefore insulating properties. When these materials do not provide sufficient structural or design performance, limiting the thermal mass of materials with relatively low specific heat provides a faster temperature equilibrium with the heated vapor material to minimize condensate formation. Where possible, limiting the contact between the vapor and materials with low specific heat also limits condensate formation. Since undesirable contact will draw heat away from the evaporating repellent, two negative effects tend to drive design considerations for the insect repellent structure and airflow path:

[0076] (1) By drawing heat from the steam onto the adjacent surface, the kinetic energy in the steam (i.e., the work required to remove the steam from the insect repellent station 12) is converted into potential energy in the material of the insect repellent station 12 (which is wasted, i.e., it heats the surface of the material).

[0077] (2) If warm steam cools on a surface, the steam is more likely to condense on that surface and not escape from the insect repellent station 12, thus negating the effectiveness of the protected area. Heating these surfaces reduces the likelihood of condensation formation, albeit at the cost of increased energy input.

[0078] Alternatively, materials for the active or passive heating insect repellent station 12 can be used to reduce the two negative effects mentioned above.

[0079] The cap assembly 20 may be made of aluminum to provide durability and safety, especially in commercial or public settings. The recycling shield 20B may be made of insulating material to prevent vapor exposure to large temperature differences. Optionally, the recycling shield 20B may be made of a low specific heat material, such as aluminum, titanium, steel, or other metals, and include structures to reduce condensation formation.

[0080] like Figure 5 and 6 As shown, the base 20A, the recycling shield 20B, and the cap 20C are formed as separate components. Alternatively, the base 20A, the recycling shield 20B, and the cap 20C can be formed as a single unit.

[0081] like Figure 8 As best shown, core 29 extends into heater aperture 68 of heater assembly 24. Heater assembly 24, including heating element 64 and generally cylindrical heater portion 66, evaporates insect repellent fluid drawn upwards through core 29 via capillary action. Upper section 16 defines an air inlet 88 between lower section 18 and an end of upper section 16 near lower section 18. The space between base 20A and recovery shield 20B defines an air / vapor outlet 90. Figure 5As shown, the air inlet 88, together with the heater assembly 24, establishes natural convection, which diffuses the evaporated insect repellent fluid outward through the air / vapor outlet 90.

[0082] When the insect repellent station 12 is in operation, the evaporated insect repellent fluid can condense as it travels outward from the heater assembly 24 (as indicated by arrow A2). Advantageously, the condensed insect repellent fluid can travel along the lower surface of the recovery shield 20B, then downward to the surface of the base 20A and along the surface of the base 20A until it is collected in the groove 80 of the heater extension member 74 as condensate drips from the edge of the opening 23 in the base 20A. Because the heater extension member 74 is attached to the heating element 64 and the cylindrical heater portion 66, the condensate collected in the groove 80 will burn off when the insect repellent station is turned on and operated.

[0083] In the illustrated embodiment, the lower segment 18 includes a cylindrical insulating sleeve 18A located within a cylindrical cover 18B, defining an internal space 96. A lower segment cover assembly 98 is mounted to the lower segment 18 and includes a lower portion 100, a cover portion 102, and a device PCBA 104 located between the lower portion 100 and the cover portion 102. The lower portion 100, cover portion 102, and device PCBA 104 are attached together, for example, by threaded fasteners 106. The lower segment cover assembly 98 is attached to the insulating sleeve 18A. In the illustrated embodiment, a threaded post 108 of the lower segment cover assembly 98 is mounted within a corresponding threaded opening 110 in the upper surface 112 of the insulating sleeve 18A. A connecting PCBA 114 extends longitudinally through a conduit channel 52 of the support arm 50 and connects a heater PCBA 60 to the device PCBA 104.

[0084] If necessary, the lower section cover assembly 98 may include a PCBA 99, such as Figure 5 and 8 As shown. The PCBA 99 is configured as a daughter card with an integrated antenna and is connected to the device PCBA 104 of the insect repellent device 12. The range of the integrated antenna of the PCBA 99 will be determined by the size and type of the insect repellent device 12 on which the PCBA 99 is mounted and the size of the refill bottle 26, wherein the size of the refill bottle 26 determines the distance to the RFID tag mounted thereon.

[0085] The RFID tag can include a unique code that identifies the type of refill bottle for the formulation fluid, allowing traceability to the manufacturer and providing additional tracking capabilities. Data from the RFID tag can be stored in a chip or in the cloud if needed. The antenna in the PCBA 99 is constructed and configured to communicate with the RFID tag attached to the refill bottle 26. The antenna and RFID tag in the PCBA 99 define near-field communication (NFC) capabilities.

[0086] The lower section 18 also includes a power on / off button 116 electrically connected to the device PCBA 104. For example... Figure 5 As shown, cable 118 is electrically connected to device PCBA 104 via a threaded connection structure for connecting insect repellent station 12 to an adjacent insect repellent station 12, to hub controller 14, or to another power source (not shown).

[0087] The lower section 18 also includes a fixed base mounting interface 18C, which allows for the attachment of various mounting structures to provide a range of positioning options when installing the linked insect repellent system 10. The fixed base mounting interface 18C is mounted in the lower end of the lower section 18 and includes an attachment point 18D. Figure 5 The diagram shows a threaded hole that receives a complementary threaded attachment member of the mounting structure, such as a ground pile as described below.

[0088] It should be understood that if the insect repellent station 12 is not straight (i.e., its longitudinal axis is not perpendicular to the ground), the ToF sensor 86 may not provide an accurate reading of the insect repellent fluid height in the refill bottle 26. Therefore, the insect repellent station 12 may be equipped with a tilt sensor (not shown), for example, in the upper section 16. The tilt sensor will help correct the insect repellent fluid height read by the ToF sensor 86. The tilt sensor can also provide feedback to the user if the insect repellent station 12 is subjected to impact when attached to the stake and installed on the ground, or if it is not installed correctly.

[0089] Now for reference Figures 18 to 21 The hub controller 14 includes a hub controller body 150. A power button assembly 152 is mounted within the surface 150A of the hub controller body 150 (when viewed from below). Figure 19 and 20(The surface facing upwards). The power button assembly 152 includes a button housing 154. In the illustrated embodiment, the button housing 154 is mounted within surface 150A of the hub controller body 150 via a threaded connection. The power button 156 is mounted within the button housing 154 and secured therein by a retainer (e.g., the retaining washer 158 shown in the figure). A flexible sealing membrane 160 is generally cylindrical and is mounted between the outer surface of the power button 156 and the inner surface of the button housing 154. When pressed by a user, the power button 156 engages the on / off power switch 162 mounted on the hub controller PCBA 164.

[0090] The hub controller body 150 includes a recess 166 defining space for cables. Additionally, the hub controller body 150 includes a removably attached mounting plate 168. The lower surface 150B of the hub controller body 150 includes a mounting tab 170 defining a mounting slot 172. The mounting plate 168 can be attached to a mounting surface, such as a wall, for example, using a threaded fastener (not shown). When the mounting plate 168 is mounted to a desired wall or other surface, the hub controller body 150 can slide onto the mounting plate 168 such that a portion of the mounting plate 168 slides or inserts into and locks into the slot 172, for example, via a snap-fit ​​connection structure.

[0091] like Figure 21 As best shown, hub controller 14 includes a power input module (PEM) 174 for connection to a power supply. Cable 176 can be easily installed and removed from PEM 174. Furthermore, a fuse 178 is provided in PEM 174, which is easily replaceable from outside the hub controller 14. Advantageously, the illustrated embodiment of hub controller 14 with removable cable 176 reduces the risk of power interruption or permanent damage in the event of an overload and allows hub controller 14 to accept different cable variations, such as standard cables for the United States and cables for Europe with only ferrite added to cable 176.

[0092] As described above, the illustrated hub controller 14 provides power and control to the linked insect repellent stations 12. As shown, the hub controller 14 can be a standalone structure or integrated into one or all of the insect repellent stations 12. The hub controller 14 can be configured as a timer to power on and off the insect repellent stations 12 in response to user time input, or as a photoelectric sensor or electronic eye to power on one or more insect repellent stations 12 in response to changes in outdoor light, or as a manually on / off switch.

[0093] Optionally, the hub controller 14 can execute a control algorithm that, in response to certain inputs indicating insect volume and density (also known as insect stress), energizes the heater assembly 14 of one or more linked insect repellent stations 12. In one embodiment, the target insect may primarily be mosquitoes, and the control inputs are factors related to mosquito presence. Some inputs are based on transient conditions, such as predicted weather events and patterns, while others are based on geography, such as proximity to water bodies and certain terrain features that may promote mosquito presence. Examples of transient condition input parameters include, but are not limited to, time of year, wind speed, temperature, humidity, and precipitation over time. These transient inputs may be available from web-based meteorological data providers or obtained in the field via meteorological instruments. Examples of geographical input factors include, but are not limited to, location coordinates, elevation, map topography of still water, and manual input factors for specific local conditions.

[0094] The hub controller 14 determines mosquito or insect stress based on selected parameters known to promote or increase mosquito populations. The hub controller 14 powers a heater assembly 24, which evaporates a known volume of repellent fluid over a specific time period. This provides a material density factor for a given area, resulting in an output that provides the desired level of insect control. Optionally, the hub controller 14 may include different heating schedules for use with different insect chemicals for various purposes. For example, cypermethrin may be used to repel mosquitoes in all or only a few of the repellent stations 12. Other repellent stations 12 may include repellent fluids targeting other insects or animals, such as dogs, cats, deer, skunks, etc. The hub controller 14 may operate each repellent station 12 differently depending on the type of repellent fluid and the location of the repellent station 12 relative to its environment. Optionally, if desired, the fluid in one or more repellent stations 12 may be formulated to attract certain desired wildlife, such as hummingbirds, butterflies, etc.

[0095] In one operating arrangement, hub controller 14 can use a closed-loop control algorithm to operate heater assembly 24 to operate heating element 64 to volatilize insect repellent fluid in a matrix (e.g., core 29). Heater assembly 24 is cyclically operated to create a heated zone around core 29 at one or more temperature profiles matched to one or more insect repellent fluid formulations. In the closed-loop control system, the power of heater assembly 24 is adjusted based on the relationship between temperature sensor output and near-target temperatures. If the temperature sensor output is below a lower threshold, power is supplied to heater assembly 24 until an upper threshold is reached, at which point heater assembly 24 is de-energized. Once de-energized, heater assembly 24 begins to cool and receives power again when the lower threshold is reached. This cycle continues, resulting in a stable and consistent temperature between the upper and lower threshold setpoints. These upper and lower temperature thresholds limit the operating temperature of the heater. Modifying the upper and lower temperature thresholds allows the operating temperature of insect repellent station 12 to move up and down. Varying thresholds allow the use of different volatile materials within the same insect repellent station 12. The thresholds can be further changed locally or remotely to adjust system performance. In some embodiments, the temperature setpoint can trigger notifications regarding performance and diagnostics. In one example, when a temperature threshold above the normal range is exceeded, hub controller 14 can trigger a fault notification and / or disable the insect repellent.

[0096] Furthermore, the fluid reservoir bottle 22 may include a chip or other data source (not shown) to indicate the type of insect repellent fluid present, as well as other information such as the volume of the refill bottle 26 and the capillary matrix material or porosity, which can alter or guide the circulation and temperature distribution of the heater assembly 24. The chip may communicate via mounting holes in the mounting housing 40 or contacts in the stop structure 44, which in turn communicates via mating contacts in the attachment boss 46 of the heater assembly 24. A temperature sensor (not shown), such as a negative temperature coefficient (NTC) thermistor, may be provided to determine the temperature of the heating element 64 and the heater portion 66, and said temperature may be used in a feedback loop to adjust the power of the heater assembly 24 to achieve a target temperature level. Alternatively, the temperature sensor may be a positive temperature coefficient (PTC) thermistor used in conjunction with an open-loop control system to produce a similar temperature profile.

[0097] Hub controller 14 may also include an analog antenna and a WiFi-enabled antenna to provide communication with information sources for various inputs to control algorithms. These inputs may include remote control access to provide operational functionality from a remote control, smartphone, computer, or similar device. Hub controller 14 may include a single antenna or multiple antennas for any type of desired communication. Operating parameters and usage data may be transmitted to a remote display showing the operating status of the insect repellent station 12, fluid fill height, lighting status, and operating schedule, as well as other data. If desired, hub controller 14 may also include manual over-control or manual discharge intensity features to allow operation without the use of instantaneous and geographical inputs.

[0098] If needed, the control and / or power characteristics of the hub controller 14 shown can be integrated into one or more insect repellent stations 12, thereby allowing a single insect repellent station 12 to operate independently or multiple insect repellent stations 12 to operate together. Each insect repellent station 12 can communicate via wired or wireless connection, provides self-addressing functionality upon startup, and reports operating parameters of each station during operation for performance monitoring, troubleshooting, and analysis. Furthermore, the insect repellent station 12 may include sensors embedded in the refill bottle 26 or the mounting cover 40, which convey information about the type of insect repellent fluid in the refill bottle 26, the appropriate heating cycle and / or heating parameters for evaporating the contents, the amount of insect repellent fluid in the refill bottle 26, and / or the manufacturer of the refill bottle 26 and its contents.

[0099] Advantageously, such as Figures 15 to 17 As shown, the embodiment of the insect repellent station 12 described and illustrated herein is configured and manufactured with a modular design that allows for improved manufacturability, an improved assembly process, and easy access for replacement of components if they become damaged or malfunction. For example, the modular insect repellent station 12 includes a removable power bulkhead (i.e., upper section 16), removable and replaceable aesthetic veneers (e.g., shields 16B and 18B), and sealed areas for PCBAA 60, 104, and 114 (which can be easily accessed).

[0100] Figure 22 shows an insect repellent station 12 installed on a known ground stake 200. The ground stake 200 has a cross-shaped cross section (when viewed from above), the stake body 202 has four elongated beams or blades 204 and a mounting flange (not shown), the mounting flange having threaded mounting posts (not shown) extending outward from the mounting flange.

[0101] Figure 23 shows an alternative known ground pile 206. The ground pile 206 has a cross-shaped cross section (when viewed from the top), the pile body 208 has four elongated beams or blades 210 and a mounting flange 212, the mounting flange 212 having threaded mounting posts 214 extending outward from the mounting flange 212.

[0102] Each of the ground stakes 200 and 206 is rigid, made of aluminum, and approximately 8.6 inches long. For users, stakes 200 and 206 may be difficult to install in hard ground because they may not be able to push their full length into the ground. Furthermore, if the insect repellent station 12 is subjected to impact while mounted on stakes 200 and 206 and installed in the ground, the force on the insect repellent station 12 can be directed to the mounting feature structure, such as the threaded mounting post 214, causing the mounting feature structure to break due to the rigidity of the combined insect repellent station 12 and the attached stakes 200 and 203.

[0103] The first alternative embodiment of the ground pile is in Figures 24 to 26 As shown in 216, it is constructed and manufactured to absorb the impact on the insect repellent station 12.

[0104] The pile 216 shown has a conventional Y-shaped cross-section (when viewed from above), a pile body 218 with three slender beams or blades 220, and a mounting flange 222 (when viewed from above). Figure 24 (See the upper surface). Cavity 224 is centrally formed in the upper portion of flange 222 and post 218. Bolts defining threaded mounting post 226 are molded into resilient housing or membrane 228, and the combined membrane-mount post assembly 230 is mounted within cavity 224. Membrane 228 can be made of any desired resilient material, including but not limited to silicone. Mounting post 226 is configured to be threaded into threaded opening 18D in insect repellent station 12, as shown. Figure 5 As best shown. The pile 218 illustrated can be formed from any desired material, such as plastic.

[0105] As shown, when the insect repellent station 12 is installed onto the ground stake 216 and subjected to impact, the insect repellent station 12 will bend up to 1 cm, while the ground stake 216 remains fixed in place in the ground G, as... Figure 26 Arrow C in the figure shows a gap of approximately 1 cm between the insect repellent station 12 and the ground stake 216 when the insect repellent station 12 is subjected to an impact force.

[0106] Now for reference Figure 27 and 28 This illustrates a second alternative embodiment of the ground stake 250, which is configured and manufactured to disengage from the insect repellent station 12 upon impact.

[0107] The illustrated ground stake 250 includes a stake body (e.g., stake body 208 as described above) and a ball 252 mounted to a mounting flange 254. As described above, instead of the threaded opening 18D, the insect repellent station 12 includes a ball socket 256, within which the ball 252 is mounted.

[0108] It has been demonstrated that when the insect repellent station 12 is installed on the ground stake 250 and subjected to impact, the insect repellent station 12 will disengage from the ground stake 250 without damaging the ground stake 250 or the insect repellent station 12.

[0109] Figure 27 An alternative embodiment of the ball 258 and the corresponding ball socket 260 is shown, which is configured for use in the insect repellent station 12.

[0110] Now for reference Figure 29 and 30 An embodiment of a spring interface 300 is shown, configured and manufactured to absorb impacts on the insect repellent station 292. As shown, the spring interface 300 is mounted to a stake, such as stake 206, and further installed within the lower end of the insect repellent station 292. Figure 29 and 30 As shown, the insect repellent station 292 includes a lower housing 294 similar to the lower housing 18.

[0111] Spring interface 300 includes mounting interface 302, which has a first portion 304, a second portion 306, and a third portion 308 (when viewed) Figure 30 (The bottommost part). The first part 304 includes a centrally formed opening 310 and may include a plurality of walls 312 extending longitudinally and radially. The second part 306 includes a centrally formed hole 314. The third part 308 includes a threaded hole 316 configured to receive a threaded mounting post 214.

[0112] A spring anchor 318 extends through a centrally formed opening 310 in the first portion 304 and includes a threaded anchor hole 320. A bolt 322 extends through a centrally formed hole 314 in the second portion 306 and is screwed into the threaded anchor hole 320 of the spring anchor 318, thereby mounting the spring anchor 318 to the second portion 306. A spring 324 (e.g., a helical tension spring) extends between the upper transverse wall 326 of the lower housing 300 and the spring anchor 318. A third portion 308 is attached to the second portion 306, for example, via a threaded fastener 307. A threaded mounting post 214 of the pile body 208 of the ground stake 206 is screwed into a threaded hole 316 in the third portion 308, thereby attaching the ground stake 206 to the spring interface 300.

[0113] Advantageously, the ground stake 206 is rigidly connected to the third portion 308 of the lower housing 300. It has been shown that when the insect repellent station 292 is mounted to the ground stake 206 and subjected to impact, the spring 324 will allow the insect repellent station 292 to flex relative to the ground stake 206 and between the first portion 304 and the second portion 306, thereby allowing the insect repellent station 292 to pivot about the fixed ground stake 206. After the impact force is removed, the insect repellent station 292 will quickly return to its initial position on the ground stake 206 due to the force of the spring 324.

[0114] The principles and operating modes of the present invention have been explained and described in their preferred embodiments. However, it must be understood that the present invention may be practiced in ways different from the specific explanations and descriptions without departing from the spirit or scope of the invention.
