Definitions

  • This invention relates broadly to battery operated fluid pumps. More particularly, this invention relates to a compact battery operated fluid pump contained in a spray head which fits onto existing pump spray containers and which exhibits improved balance.
  • the propellant can be environmentally unfriendly. While environmentally friendly propellants do exist, generally, they do not charge as well as the unfriendly gases.
  • Still another popular sprayer is the air pump sprayer seen most frequently with insecticides and liquid garden products.
  • the air pump sprayer includes a hand operated air pump which is used to charge the container with compressed air. After it is charged, it operates much like an aerosol can.
  • the pump sprayer is environmentally friendly but requires considerable effort to keep charged because air is not as efficient a propellant as environmentally unfriendly gases such as FREON or hydrocarbon gasses.
  • battery powered pump sprayers Most of these devices include a spray mechanism which is similar to the ubiquitous push button (or trigger) pump sprayer but which is coupled to a battery powered electric motor by some type of linkage which converts the rotary action of the motor into an oscillatory motion to drive the pump piston.
  • Many of these battery operated pump sprayers are designed to work only with a specially constructed bottle, i.e. they are not retrofittable to existing pump spray bottles.
  • Some battery operated pump sprayers use small ineffective diaphragm pumps or arrange a piston pump so that it extends down into the spray bottle. While these designs may provide better balance, they give rise to new disadvantages.
  • the diaphragm pumps do not work as well as piston pumps. Arranging the pump inside the bottle displaces liquid in the bottle and subjects pump elements to submersion which requires additional design considerations.
  • a battery operated spray pump includes a pump having an inlet and an outlet, the outlet defining a pump axis coaxial with the outlet.
  • the pump is mounted inside a spray head having a nozzle, the nozzle defining a discharge axis which is coaxial with the nozzle.
  • the pump axis and the discharge axis are neither collinear nor parallel nor perpendicular but are arranged at an angle of 30-60 degrees relative to each other. More particularly, the pump axis is angled up relative to the discharge axis with the pump outlet angled up from and lying above the discharge axis.
  • the pump outlet is therefore coupled to the nozzle by a flexible tube or an elbow.
  • the batteries are located on top of the pump.
  • the pump may be substantially the same as either of those disclosed in the previously incorporated applications but modified to allow the pump axis to be arranged at an angle relative to the discharge axis.
  • Fig. 1 is a side elevational view of a spray head according to the invention coupled to a conventional bottle;
  • Fig. 2 is a broken perspective view showing a front side of the spray head
  • Fig. 3 is a broken perspective view showing a rear side of the spray head
  • Fig. 4 is a broken, partially transparent and partially cut-away view showing a first side of the spray head
  • Fig. 5 is a broken, partially transparent and partially cut-away view showing a second side of the spray head.
  • Fig. 6 is an exploded perspective view of the components of the spray head. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • a battery operated spray head 10 includes an ergonomic housing 12 coupled to a threaded bottle coupling 14 and including an adjustable nozzle 16 and a trigger 18.
  • the rear upper portion of the housing 12 includes a battery compartment door 21.
  • the coupling 14 is designed to fit on a standard bottle 1 having a 28mm threaded opening 2. These are the bottles most typically used with conventional spray heads for household products such as cleaners, fabric sprays, etc.
  • the power source (batteries) 22, an electric motor 24, a transmission 26, and a piston pump 28.
  • the illustrated embodiment shows the piston pump which is described in detail in previously incorporated 11/034,600, the pump described in previously incorporated 60/624,647 could be used. Moreover, any electric pump of suitable size could be used.
  • the trigger 18 is arranged so that when it is squeezed, it operates a valve 30 and an electrical switch 32.
  • the illustrated switch is a standard microswitch, but other types of switches could be used.
  • the inlet of the pump 28 is always fluidly coupled to the interior of the bottle 1 via a tube 34 which is coupled to another longer tube (not shown) which extends deep into the bottle.
  • the valve 30 opens an air path from the atmosphere to the interior of the bottle 1. It will be appreciated, however, that the double valve arrangement could be used in this spray head.
  • the housing 12 has an upper part 12a and a lower part 12b.
  • a battery compartment 20 is located inside the door 21. The door is removable so that the batteries 22 may be replaced as needed.
  • the illustrated batteries are two AA alkaline batteries and the design is optimized for batteries having the mass of two AA batteries. Other batteries of the same or similar mass could be used or the design could be modified if needed to accommodate a battery or batteries of different mass.
  • the battery compartment 20 also includes contacts 23 which couple opposite poles of two batteries 22 in series with each other and contacts 25 which couple opposite poles of batteries 22 to the motor (24 in Figure 5) via the switch 32 using wires (not shown).
  • the nozzle 16 includes spin mechanics 16a and nozzle adapter 16b.
  • the valve 30 includes a piston 30a and a spring 30b.
  • the axis of the pump 28 is not collinear with or parallel to the axis of the nozzle assembly 16, 16a, 16b which assumes a substantially horizontal orientation ( ⁇ 10 degrees). More particularly, the outlet of the pump is raised up from the normal position of facing directly at the nozzle. This can be described as having an outlet vector with a horizontal component facing in the same direction as the horizontal component of the nozzle outlet vector.
  • the angle between the pump axis and the nozzle assembly axis is preferably between 30 degrees and 60 degrees.
  • the pump inlet 28a (which contains the ball valve described in the previously incorporated application) is arranged to be vertical and therefore assumes an angle relative to the pump axis and is not collinear with the center of the coupling 14.
  • flexible tubes 34 and 35 are used to couple the inlet 28a to the bottle coupling 14 and the outlet 28b to the nozzle 16.
  • the batteries 22 are arranged on top of the pump assembly and substantially parallel ( ⁇ 10 degrees) to the pump axis.
  • the front to back dimension of the spray head is substantially shortened and the center of gravity of the spray head is moved closer to the vertical axis of the bottle. This allows the substantially the entire spray head (i.e., at least 90% of the spray head) to lie within the footprint of the bottle (i.e., within the projection of the bottle to a horizontal surface on which the bottle stands) and provides better balance.
  • the lower rear portion of the housing 12 is larger than it needs to be to enclose the internal components. This is to provide an ergonomic form factor wherein the lower rear portion of the housing can rest comfortably on the user's hand when the trigger is squeezed.

Abstract

L'invention concerne une pompe de pulvérisateur mise en oeuvre au moyen d'une batterie et comprenant une pompe à piston, l'axe de la pompe étant disposé au niveau d'un angle par rapport à l'axe de la décharge du pulvérisateur et à l'admission de fluide. De plus, les batteries se trouvent sensiblement sur le sommet de la pompe plutôt que derrière celle-ci, permettant ainsi à la tête du pulvérisateur de présenter une dimension globale presque totalement comprise dans l'encombrement d'une bouteille sur laquelle ladite tête fixée et conférant également à celle-ci un meilleur équilibre.
