3 Claims.

The present invention relates to odor dispensers in general and particularly to a new and novel odor-dispensing unit for a suction cleaner. More specifically, the invention comprises an odor-dispensing unit Which is adapted to be connected in a dusting tool unit connected to a suction cleaner for the purpose of conditioning air passing thru the unit.

It is an object of the invention to provide a new and improved odor dispenser for a suction cleaner. It is another object of the invention to provide an odor dispenser adapted to be posi tioned in a dusting tool hose. A still further object is the provision of a dusting tool odor dispenser comprising means tomount the odor dispenser unit at a joint in the dusting tools and means to support a volatile element unit. Still another object is the provision of' an economically manufactured odor dispenser unit comprising means to mount the unit in a dusting, tool hose and means to removably seat a replaceable volatile unit. These and other more specific objects will appear upon reading the following specification and claims and upon considering in connection therewith the attached drawing to which they relate.

Referring now to the drawing in which a preferred embodiment of the invention is disclosed:

Figure l is a disclosure of a suction cleaner combined with dusting tools in which the odor dispenser unit constructed in accordance with the present invention is mounted;

Figure 2 is a view in perspective of the odor dispenser unit comprising the present invention, the closure cap of the volatile element container being removed;

Figure 3 is an enlarged showing of the relationship existing between the odor dispenser unit and the dusting tool hose, being a section taken upon the line 33 of Figure 4;

Figure 4 is a view similar to Figure 3 but is taken with the parts rotated thru an angle of 90 degrees;

Figure 5 is a section upon the line 5-5 of Figure 3.

Referring now to Figure 1 in particular, a modern suction cleaner is disclosed the casing of which comprises a nozzle I, a fan chamber 2 which is interiorly connected to the nozzle, an exhaust outlet 3, and a motor casing 4. An unshown motor is positioned Within the motor casing 4 and its extended end carries the suctioncreating fan 5 within the fan chamber 2. Fan 5 functions to create a reduced pressure in the nozzle I to draw cleaning air therethrough when the machine is used as an on-the-floor cleaner. To aid in floor cleaning an agitator i is positioned Within the nozzle I and is adapted to agitate a surface covering undergoing cleaning. The cleaner is movably supported in a common manner by front and rear wheels indicated by the reference characters l and8. In order to adjust the height of the nozzle and so the position of agitator 6 relative to a surface covering undergoing cleaning, height-adjusting means 9 are provided for the rear supporting wheels. The usual pivoted handle I0 is provided which makes possible the propulsion of the cleaner by the operator, theincoming power leads II entering the handle near its upper end and passing downwardly therethrough to enter the cleaner casing.

In the usual operation of the suction cleaner as an on-the-floorcleaner, a suitable dustbag is secured to the exhaust outlet 3 by the manually operable clamping means I2, and receives the dirt-laden air expelled from the cleaner proper by the rotating fan 5. When it is desired, however, to use the cleaner as a blowing unit, the dust bag is removed and in its place a dusting tool unit comprising a connector I3, a flexible elongated hose I4, and a dusting tool nozzle I5, is connected. Connector I3 is so shaped that it is adapted to seat upon the exhaust outlet 3 and to be clamped thereto by the means I2. The elongated flexible tubular hose I4 is removably seated upon the connector I3, being retained thereon normally by locking means indicated generally by the reference character I6. At its outer end the dusting tool hose I4 is protected by an overhanging metallic collar 20 and is provided with a metallic cylindrical sleeve II, the outer end of which is formed with a detent seat I8 comprising a circumferential groove defined at its outer side by a radial wall and an overhanging shoulder. The dusting tool nozzle I5 is formed with a tubular end I9 which is adapted to enclose and seat sleeve H, the sleeve telescoping into the nozzle until its outer end, defined by the end wall of groove I8, abuts an internal circular shoulder 2| in sleeve I9, the end of tube I9 abutting collar 25. With the nozzle so positioned upon the sleeve, 2, spring-pressed detent 22 carried by the nozzle is adapted to seat within the circumferential groove i8 and to prevent the longitudinal separation of the two parts.

The odor dispenser constructed in accordance with the present invention includes a flanged collar 25 which is of such size that its body is adapted to seat snugly within the end of sleeve H, the flange thereon abutting the end wall of seat l8. The collar flange is so dimensioned that it closely seats within the tube [9 at the end of nozzle IE but cannot pass the abutment shoulder 2|. A metallic container seat 26 of circular cross-section and split longitudinally for its entire length along its side is positioned in the collar 25, the seat being provided with a raised shoulder 2'! which is suitably secured to the inside of the collar, as by welding. The container seat may be of any suitable material so long as it is characterized by a certain resilience or flexibility permitting it to function as a frictional clamping seat for a body positioned within it. Within seat 26 is positioned a vial 28 which may be of glass and which is formed with a threaded mouth adapted to removably seat a cap 29. An inturned lip 30 on seat 26 contacts the end of the vial and prevents movement in one direction. Within vial 28 is positioned a redolent volatile material 3! which may be a volatile oil carried by an absorbent material or may be a cake of suitable volatile material.

To incorporate the odor dispenser unit comprising the present invention into the dusting tool unit, it is only necessary to position the volatile element container 28 in its seat 26 where it will be frictionally clamped and longitudinally positioned by the stop 30. The cap 29 of the container should be removed and the collar 25 seated upon the end of metallic sleeve I! with the open end of the vial facing the cleaner end of the hose 4. The dusting tool nozzle I5 can then be telescoped over the collar 25 and the sleeve H, the play between the locking detent 2| and its seat l3 being sufiicient to accommodate the thickness of the flange of collar 25 between shoulder 2| and the abutting wall of groove l8.

With the nozzle locked to the dusting tool hose and the odor dispenser unit seated therein the construction is ready for use. The closing of the electrical circuit to the cleaner functions to cause the unshown motor to rotate the suctioncreating fan 5 which draws air from the nozzle l and exhausts it through the exhaust outlet 3.

In this operation and use of the cleaner, the height-adjusting means 9 should be so adjusted that the nozzle l is raised a considerable distance above the supporting surface in order that the flow of air into the nozzle will be unrestricted, and also that the agitator 6 will not contact the adjacent surface covering. The air exhausted through the exhaust outlet 3 passes through the dusting tool hose M and by the odor dispenser unit, a considerable part of the air entering the mouth of the vial 28 to contact the volatile element therein. The user may direct the resultant vapor by means of pointing nozzle I5 any desired direction.

While in the present disclosure the odor dispenser unit has been illustrated as seated at the joint between the nozzle and the dusting tool hose, it is to be understood that it is capable of being positioned at any joint in the dusting tool unit which is similarly constructed.

I claim:

1. In an odor dispenser for suction cleaners of the type having jointed dusting tools, a flanged collar adapted to be clamped between abutting ends of two dusting tool elements, a split resilient seat member carried by said collar, and an open-ended vial seated in said seat with its major axis parallel to the central axis of said collar.

2. In an odor dispenser for suction cleaners, a collar having a radially extending flange, a split resilient metallic sleeve of circular cross section secured to and positioned concentrically in said collar, and a volatile element container removably clamped in said sleeve.

3. In an odor dispenser for suction cleaners, a collar having a radially extending flange, a split resilient metallic sleeve of circular cross section secured to and positioned concentrically in said collar, and a. vial including a removable closure and containing a volatile redolent element seated in said sleeve.
