Abstract

A fragrancing device is disclosed. The fragrancing device includes a housing having an installation space and a longitudinal housing axis at which a carrier is arranged with contact. The carrier is provided separately with respect to the housing and includes a cover part that covers an installation space opening of the installation space. A carrier part having at least one fragrance cartridge receptacle for receiving a fragrance cartridge is provided. A guide stop is disposed axially in a direction of the housing axis between the carrier and the housing for guiding the carrier as part of a plug-in movement relative to the housing along the housing axis. The guide stop includes a guide pin and a guide pin receptacle.

First claim

The invention claimed is:

1. A fragrancing device, comprising:
a housing having an installation space and a longitudinal housing axis, and a carrier arranged at the housing with contact, the carrier formed separately with respect to the housing and includes a cover part structured and arranged to cover an installation space opening of the installation space, and a carrier part having at least one fragrance cartridge receptacle for receiving a fragrance cartridge,
a guide stop disposed axially in a direction of the longitudinal housing axis between the carrier and the housing for guiding the carrier as part of a plug-in movement relative to the housing along the longitudinal housing axis,
wherein the guide stop includes a guide pin and a guide pin receptacle.

2. The fragrancing device according to claim 1 , wherein the guide pin and the guide pin receptacle engage with one another with contact in a slidably displaceable manner to guide the carrier as part of the plug-in movement relative to the housing along the longitudinal housing axis between an installed state of the carrier, arranged or inserted completely at the housing, and mounting states spaced apart therefrom in the longitudinal housing axis.

3. The fragrancing device according to claim 1 , wherein the guide pin is a cylinder sleeve having a longitudinal guide pin axis.

4. The fragrancing device according to claim 3 , wherein the cylinder sleeve is slotted to provide slots that are arranged equidistantly spaced apart from one another in a cylinder sleeve circumferential direction around the longitudinal guide pin axis and in a direction of the cylinder sleeve circumferential direction.

5. The fragrancing device according to claim 4 , wherein the cylinder sleeve has at least one cylinder sleeve front face, wherein the slots each lead to the at least one cylinder sleeve front face by forming an internal insertion slot opening in a direction of the longitudinal guide pin axis, and wherein at least one of the slots is flanked in a frame-like manner on both sides in the cylinder sleeve circumferential direction by introducers that are arranged at the cylinder sleeve and which extend at least section by section in the direction of the longitudinal guide pin axis along the at least one slot.

6. The fragrancing device according to claim 5 , wherein the introducers are defined by a lead-in bevel or a lead-in ramp or a lead-in curve.

7. The fragrancing device according to claim 3 , wherein the cylinder sleeve has an outer jacket surface and protrusions arranged at the outer jacket surface, the protrusions protrude radially outwards with respect to the longitudinal guide pin axis and are spaced apart equidistantly from one another in a cylinder receiving sleeve circumferential direction around the longitudinal guide pin axis.

8. The fragrancing device according to claim 7 , wherein the protrusions each have a protrusion bevel or a protrusion ramp or a protrusion curve that slopes radially outwards with respect to the longitudinal guide pin axis.

9. The fragrancing device according to claim 1 , wherein the guide pin receptacle is a cylinder receiving sleeve that has a longitudinal guide pin receptacle axis.

10. The fragrancing device according to claim 9 , wherein the cylinder receiving sleeve has an inner jacket receiving surface and at least one positioning protrusion arranged at the inner jacket receiving surface, the at least one positioning protrusion protrudes radially inwards with respect to the longitudinal guide pin receptacle axis.

11. The fragrancing device according to claim 10 , wherein the cylinder receiving sleeve has at least one cylinder receiving sleeve front face with respect to which a positioning protrusion is arranged at the inner jacket receiving surface with a longitudinal distance in a direction of the longitudinal guide pin receptacle axis.

12. The fragrancing device according to claim 5 , wherein the cylinder receiving sleeve defines an internal insertion space that is enclosed at least section by section in a rotating manner by the inner jacket receiving surface, and into which the cylinder sleeve can be inserted so as to dip in as part of the partial insertion movement of the plug-in movement, wherein, as part of the partial insertion movement, at least one positioning protrusion of the cylinder receiving sleeve slides with contact along the introducer of the cylinder sleeve, and wherein, as part of the partial insertion movement, the at least one positioning protrusion of the cylinder receiving sleeve engages with contact with a slot of the cylinder sleeve to at least one of center and position the cylinder receiving sleeve with respect to the cylinder sleeve in one of a cylinder sleeve circumferential direction and a cylinder receiving sleeve circumferential direction according to a specified or specifiable angular position.

13. The fragrancing device according to claim 11 , wherein as part of the partial insertion movement, the cylinder receiving sleeve front face slides with contact along at least one protrusion of the cylinder sleeve to at least one of center and position the cylinder receiving sleeve with respect to the cylinder sleeve.

14. The fragrancing device according to claim 1 , wherein:
at least in the installed state of the carrier, when attached to the housing, the guide pin and the guide pin receptacle are each centrally aligned with respect to the longitudinal housing axis, or
at least in the installed state of the carrier, the longitudinal guide pin axis of the guide pin and the longitudinal guide pin receptacle axis of the guide pin receptacle are centrally aligned with respect to the longitudinal housing axis.

15. The fragrancing device according to claim 1 , wherein one of:
the guide pin is arranged at the housing or at the carrier,
the guide pin is arranged via a substance-to-substance bond at the housing or at the carrier, and
the guide pin is provided as a separate component and is arranged in at least one of a positive and non-positive manner at the housing or at the carrier.

16. The fragrancing device according to claim 1 , wherein one of:
the guide pin receptacle is arranged at the housing or at the carrier,
the guide pin receptacle is arranged via a substance-to-substance bond at the housing or at the carrier, and
the guide pin receptacle is provided as a separate component and is arranged in at least one of a positive and a non-positive manner at the housing or at the carrier.

17. The fragrancing device according to claim 1 , wherein the guide stop includes a locking assembly for releasably fixing the carrier to the housing in the installed state of the carrier.

18. The fragrancing device according to claim 17 , wherein the locking assembly has male locking parts that are arranged at the cover part or at an edge cover part of the cover part, the male locking parts elastically engage with one another at least in the installed state of the carrier to block a partial insertion counter movement of the carrier relative to the housing in a direction opposite to the partial insertion movement along the longitudinal housing axis to secure the carrier to the housing against unintentionally falling out.

19. The fragrancing device according to claim 1 , wherein at least one of:
in the installed state of the carrier, when attached completely to the housing, the cover part of the carrier completely covers an internal installation space opening of the installation space, and
a sealing element is arranged at the cover part or at a middle cover p
