Cleaning Agent Dispenser for a Flushing Tank

Abstract

A dispenser for dispensing a determined quantity of a liquid treating agent in a flush tank includes at least one metering cavity whose volume is close to the volume of the dose of a dispensable product, first part for communicating the cavity with a product storage tank, second part for controllingly connecting the cavity with outside, closing elements of the second part, which are controlled by a member floatingly mounted on a surface of water contained the flush tank and make it possible to close them during the waiting phase of the flushing device and to open the part when the flushing device is actuated.

1 . A device for dispensing a set quantity of a treatment liquid product ( 6 ) into the reservoir ( 3 ) of a WC flush mechanism, during the operation of the WC flush mechanism comprising:
 at least one measuring cavity ( 12 ) whose volume (V) is close to a volume of a quantity (V+v) of product to be dispensed,   first means ( 14 ) for bringing this cavity into communication ( 12 ) with a storage reservoir ( 2 ) for the said product ( 6 ),   second means ( 19 ) for arranging controlled communication of this cavity ( 12 ) with the reservoir ( 3 ) of the WC flush mechanism, the pressure drop of the first means ( 14 ) being at least five times that of the pressure drop of the second means ( 19 ),   a vent ( 16 ) for putting the said cavity ( 12 ) in communication with the exterior, and   stopper elements ( 28 ,  39 ) of the second means ( 19 ), controlled by a device ( 32 ) that is mounted so that it floats on the surface (N) of the water contained in the reservoir ( 3 ) of the flush mechanism, and that is used to shut them off during the wait phase of the WC flush and to open them during the operation of the latter.   
   
   
       2 . The device according to  claim 1 , wherein the measuring cavity ( 12 ) is positioned inside of a vertical cylindrical element ( 10 ) traversing the storage reservoir ( 2 ). 
   
   
       3 . The device according to  claim 1 , wherein the measuring cavity ( 12 ) is positioned below the storage reservoir ( 2 ). 
   
   
       4 . The device according to  claim 1 , wherein the first means for putting the measuring cavity ( 12 ) into communication with the storage reservoir ( 2 ) are composed of an intake orifice ( 14 ). 
   
   
       5 . The device according to  claim 1 , wherein the measuring cavity ( 12 ) is closed at its bottom part by closure means ( 17 ) traversed by an outlet channel ( 19 ) whose cross section is at least five times that of the intake orifice ( 14 ). 
   
   
       6 . The device according to  claim 1 , wherein the stopper elements are composed of a valve ( 28 ,  39 ) whose operation is controlled from the said floating device ( 32 ). 
   
   
       7 . The device according to  claim 6 , wherein the valve ( 28 ,  39 ) is mounted so that it moves in translation. 
   
   
       8 . The device according to  claim 6 , wherein the valve ( 28 ,  39 ) is mounted so that it moves in rotation. 
   
   
       9 . The device according to  claim 1 , further comprising: means that are designed to put an additional reservoir ( 44 ) in communication with the measuring cavity ( 12 ), so as to increase the volume (V+V′+v) of the product ( 6 ) delivered. 
   
   
       10 . The device according to  claim 1 , wherein the said device, mounted to float ( 32 ), is hollowed out at its top part, with a cavity ( 45 ) that is intended to receive the product dispensed by the stopper elements ( 28 ,  39 ), extended by grooves ( 46 ) designed to dispense the said product at its surface. 
   
   
       11 . The device according to  claim 1 , wherein the top part of the storage receptacle ( 2 ) is in communication with an external fill tank ( 50 ), possibly closed by a lid ( 51 ). 
   
   
       12 . The device according to  claim 1 , wherein the reservoir ( 3 ) of the WC flush mechanism includes at least water intake orifices, one these being used to effect the fixing in the latter of the storage reservoir ( 2 ). 
   
   
       13 . The device according to  claim 12 , wherein the water intake orifices used for the fixation of the storage reservoir ( 14 ) also arrange for the putting in communication of the latter with the external fill tank ( 50 ). 
   
   
       14 . The device according to  claim 1 , further comprises the means for attachment to the internal walls of the flush reservoir ( 3 ). 
   
   
       15 . The device according to  claim 14 , wherein the fixing means are composed of two actuators, acting in opposition, and anchored on the opposite walls of the flush reservoir, with the contact between the actuators and the said walls being by means of a suction cup. 
   
   
       16 . The device according to  claim 2 , wherein the measuring cavity ( 12 ) is positioned below the storage reservoir ( 2 ).
