Definitions

  • Device for dispensing fragrances and/or active substances for example for freshening the air of vehicle cabins, and method for operating such a device
  • the invention relates to a device for dispensing fragrances and/or active substances, for example for freshening the air of vehicle cabins, according to the preamble of claim 1 , and to a method for operating a device according to the preamble of claim 19.
  • Devices with a fragrance and/or active substance generator in a housing with outflow openings are generally known in various embodiments.
  • Active vaporisation devices are known as fragrance and/or active substance generators, with which volatile substances with fragrances are released from a housing into the environment by heating liquids in particular.
  • Such active devices usually require an electrical auxiliary energy as evaporation energy and are intended in particular for building interiors.
  • devices which automatically release volatile substances at normal room temperatures without auxiliary energy.
  • corresponding materials are often contained in block form as a fragrance block in a housing with at least one outflow opening.
  • Such devices are generally known as disposable articles after the consumption of a fragrance block or with an openable housing for the exchange of a fragrance block.
  • Air freshening especially in a vehicle cabin, for example in a passenger car, is perceived as pleasant by the people present, especially at higher temperatures.
  • air freshening by a device is often not necessary and may even be perceived as annoying. Since the outflow openings in the housing of the known inactive devices are constantly open, volatile substances are permanently released, which adversely increases the consumption of a fragrance block and thus reduces the functional life of the device.
  • a further object of the invention is to provide a method for operating such a device.
  • the object of the invention is solved with respect to the device with the features of claim 1 and with respect to the method with the features of claim 17.
  • the device for dispensing fragrances and/or active substances comprises a housing for accommodating a fragrance and/or active substance generator which dispenses a fragrance and/or active substance as a volatile substance, preferably for freshening the air, the housing having at least one housing-outflow opening for the outflow of the fragrance and/or active substance.
  • the housing has at least one adjustably guided cover element which is automatically and temperature-dependently adjustable by means of a temperature-dependently actuable actuator between a closed position, in which the at least one housing-outflow opening is closed by means of the cover element to prevent the fragrance and/or active substance from escaping from the housing, and an open position. In this open position, the at least one housing-outflow opening (for the escape of fragrance and/or active substance) is completely open by means of the cover element or partially open in intermediate positions.
  • the amount of fragrance and/or active substance flowing out of the at least one housing-outflow opening and thus the degree of outflow is automatically changed depending on the temperature between no outflow and maximum outflow, if necessary with possible intermediate degrees of outflow.
  • Dimensioning and adaptation to current conditions are possible in particular by the position and size of one or more housing-outflow openings and the relative position of the cover element, if necessary with cover element-outflow openings fitted there, as well as by specifying and dimensioning the adjustment path of the bimetal actuator.
  • the degree of outflow can be preset, for example, for optimum refreshment, in particular in a vehicle cabin, for example of a passenger car, as a function of the temperature.
  • the mechanical arrangement can be designed simply and inexpensively. It is understood that the application in connection with air freshening is only exemplary here and of course other applications, e.g. in the field of pest control and/or pheromones, are also possible, just to show some further possible applications by way of example.
  • the temperature-dependently actuable actuator which operates without auxiliary power, is preferably built in a particularly simple, inexpensive and functionally reliable manner by means of a bimetallic actuator, which bimetallic actuator is, directly or indirectly, connected on the one hand to the housing and on the other hand to the cover element.
  • Bimetal actuators regularly have a bimetal strip for temperature-dependent automatic actuation and control of mechanically moving parts.
  • the bimetal strip is formed from two metal layers that are bonded or form-fitted to each other and one above the other and that have different coefficients of thermal expansion. As a result, one of the layers expands more than the other when the temperature changes, causing the bimetal strip to bend automatically.
  • the ends of the strip are fixed to components that can be moved against each other, a relative movement with a adjustment path can thus be exerted.
  • the temperature-dependently actuable actuator which is operated without any auxiliary energy, can also be designed in other ways.
  • Wax actuator These actuators use the expansion and contraction of a wax element in response to temperature changes.
  • the wax element is for example sealed in a chamber and connected to a piston or valve, which moves in response to the temperature changes.
  • SMA Shape memory alloy
  • bimetal or bimetallic actuator may be replaced at any time by the above alternatives if this is technically feasible and suitable.
  • the actuator for example a bimetal actuator
  • the actuator is suitable and/or designed to move the at least one cover element into the closed position when a defined lower temperature threshold is reached or undershot and into the open position when a defined upper temperature threshold is reached, which has a higher temperature than the lower temperature threshold, the cover element is moved into the open position, whereby at temperatures in the range between the lower temperature threshold and the upper temperature threshold, the at least one cover element is moved into intermediate positions with at least one housing-outflow opening partially open.
  • the adjustment path for the at least one cover element is limited at the closed position by a first housing-side stop element and at the open position by a second housing-side stop element, whereby the free adjustment path of the actuator is greater than the adjustment path limited by the stop elements.
  • the free adjustment path of the actuator without stop element limitation is advantageously selected to be greater than the adjustment path between the stop elements, so that the cover element is moved quickly into the closed position and into the open position, where it is pretensioned. This ensures fast, safe control that is insensitive to housing movements, such as those that can occur when driving.
  • the fragrance and/or active substance generator is to be suitable and/or designed to emit a fragrance and/or active substance when the at least one cover element is in an open position, wherein it is preferably provided that the fragrance and/or active substance generator emits a fragrance and/or active substance at least at temperatures which are equal to or higher than the lower temperature threshold. This ensures that a fragrance and/or active substance is emitted at least whenever the cover element is in an open position.
  • a fragrance and/or active substance is also emitted when the cover element is in the closed position. In this case, the fragrance and/or active substance accumulates in the device and is only released when the cover element is moved to an open position.
  • the fragrance and/or active substance generator can also be an active device in which the fragrance and/or active substance is generated with external auxiliary energy.
  • the fragrance and/or active substance generator should be a fragrance block, for example a fragrance block that consumes itself by emitting fragrance and/or active substance or in which, for example, gases stored in a space lattice structure escape by evaporation.

Overall, this results in a simple and yet functionally reliable construction of the device.
  • the lower housing can readily be the upper housing and the upper housing can correspondingly be the lower housing.
  • the lower housing may be arranged on the left (or right) side, while the upper housing is correspondingly arranged on the right (or left) side.
  • the designations “lower” and “upper” are thus to be seen as completely independent of a conventional spatial orientation, and the lower housing and the upper housing can thus be arranged in the sense of a first housing and a second housing arbitrarily in a three-dimensional space.
  • the at least one cover element preferably comprises at least one cover elementoutflow opening which, when the at least one cover element is moved into the open position, can be placed in alignment over the respectively associated at least one housing-outflow opening in such a way that the two associated openings form a common continuous opening for the escape of fragrance and/or active substance and/or that the at least one housing-outflow opening is completely open and not covered.

  • a pattern with several housing outflow openings is advantageously provided in the housing respectively in the housing outer wall of the housing, preferably in the first housing part and/or in the second housing part, and the identical pattern with several cover element outflow openings in the at least one cover element.
  • both the housing and the at least one cover element each have an identical or identical pattern with several outflow openings, which can be aligned one above the other by adjusting the cover element by means of the actuator in the open position.
  • the at least one cover element in particular in the form of a cover plate, can, for example, be guided adjustably in a linear guide on the housing, for example to provide an axial movement of the cover element relative to the housing.
  • the pivot joint can be arranged on a first side of the cover element in relation to a longitudinal direction of the cover element and the bimetal actuator can be connected to the opposite side of the cover element in relation to the longitudinal direction.
