Definitions

  • the claimed technical solution relates to the field of shower devices and is a plumbing product designed to dispense cleansers in the form of a rich foam onto human skin through the spray of the dividing head of the showerhead nozzle.
  • the foam is generated when the mixed solution, which is formed inside the showerhead nozzle body by mixing water and the cleanser, usually shower gel, passes through the mesh of the dividing head of the showerhead nozzle and mixes with air.
  • the showerhead nozzle looks no different from ordinary showerheads and can be connected to the shower hose without any additional devices.
  • the mechanism for generating foam is located inside the showerhead nozzle, where the mixing takes place.
  • the cleanser is refilled into the reservoir of the showerhead nozzle under pressure using a special dispenser that is external to the shower and not part of the showerhead nozzle construction.
  • This showerhead has the advantage of allowing users to immediately obtain foam for washing from the showerhead nozzle, making it effective for use in everyday life as well as by the elderly, sick, or immobile, since there is no need for additional effort or assistance to obtain and apply the foam to the body.
  • a special mode switch button located on the showerhead nozzle the user can choose between the foam mode and the normal mode for rinsing water flowing from the showerhead nozzle.
  • the claimed device allows for charging the showerhead nozzle with various liquid mixtures, including medicines, cosmetics, or aromatic agents, instead of liquid cleansers, depending on the intended use.
  • An analogue is known, a shower head with a wash function, according to the patent of the Russian Federation for invention No. 2742478 dated August 22, 2019 , published on February 8, 2021, which includes a hollow handle with a standard water inlet on one side and a head for dividing a single stream into multiple jets on the other side.
  • the shower head is designed to transition into an elongated holder with an additional washing head.
  • the elongated holder with the washing head has grips at the washing head to fix a washcloth stretched over it, which coincides with it in shape and size, as well as to fix external washcloths.
  • the grips are made in the form of spring-loaded clamps with pointed combs to hold the washcloth, while the washing head may have silicone or rubber protrusions on the front surface.
  • the shower head with a wash function can be made either as a single monolithic design, or the elongated holder with the washing head can be a detachable attachment with fasteners to the shower head.
  • the claimed solution and the analogue showerhead with a wash function according to Russian patent No. 2742478 share common features, such as the presence of a handle with a standard water inlet and a divider head that separates a single stream of water into multiple streams.
  • the patent for the showerhead with a wash function (RU patent No 2742478 ) includes an extended handle with an additional washing head and clamps for securing a washcloth to the washing head.
  • the claimed solution includes a reservoir integrated into the showerhead's body during manufacturing.
  • the known device for simultaneous adjustable dosed delivery of cleaning and/or medicinal agents through a showerhead (PROTOTYPE) according to the patent for invention RU2517998 dated December 21, 2012 , published on June 10, 2014, comprises a nozzle connected at the inlet to the water supply line and at the outlet to the hose for delivering cleaning and/or medicinal agents, at the end of which the showerhead is installed.
  • the nozzle contains a partition dividing it into two adjacent chambers, one of which, the main one, forms a channel for direct water flow, while the other, additional, is made in the form of a Venturi tube, the throat of which communicates with an adapter connected to a plurality of pipelines.
  • the outputs of the main and additional chambers are combined into one channel, which is connected to the user's liquid delivery hose.
  • the device also includes a two-position switch located at the inlet of the nozzle, which ensures the passage of water through one of the adjacent chambers, multiple sealed containers for cleaning agents and medicinal preparations installed on a comb equipped with controllable valves providing selective connection/disconnection of sealed containers to the adapter, and a check valve installed at the outlet of the Venturi tube to prevent water from passing through the Venturi tube when water flows through the main chamber.
  • the differences between the prototype and the claimed technical solution are due to the differences in their construction.
  • a more portable and integrated design is used, located inside the showerhead, instead of a separate attachment.
  • the prototype utilizes a Venturi tube and a comb with multiple sealed containers for the cleaning and medicinal liquids.
  • the user can obtain a mixture of water and cleaning or medicinal liquids from the showerhead, and the amount of liquid used can be regulated by adjusting the flow rate of the water from the mixer or the volume of the suctioned liquid from the containers by controlling the valve opening.
  • the claimed device allows the user to obtain a foamy cleaning solution, rather than a liquid cleaning solution or a mixture of water and cleaning solution, while simultaneously operating as a showerhead.
  • the claimed device is monolithic and has no attachments, and all the components for producing a foamy cleaning solution are inside the showerhead.
  • the advantages of the claimed device include improved portability, the ability to operate as a regular showerhead and as a foam-producing showerhead, water and cleaning solution savings, and time savings due to the showerhead's unique mechanism of operation. Additionally, the claimed device can operate at minimal water pressure, starting from 1 atm, and it can use any liquid cleaning solution.
  • the claimed solution uses a piston system to create pressure.
  • the agent is taken using the Venturi tube principle with the use of the ejection process, but this principle cannot achieve a ready-to-use foam output from the showerhead.
  • the Venturi tube principle does not work if there is resistance when the ready-to-use mixture exits, and without resistance, it is impossible to achieve the required consistency of the foam.
  • the design differences from the prototype consist of the fact that in the claimed solution, the agent reservoir is located in the handle of the showerhead, as well as the use of nozzles and meshes to obtain thick foam, and the presence of a tap for precise regulation of the density of the resulting foam during output.
  • the disadvantage of the prototype is the relative complexity of the design and material consumption, as well as the lack of an effective way to produce foam - the prototype simply dispenses a mixture of water and detergent from the showerhead, resulting in high detergent consumption. Furthermore, the scope of application is quite limited, mainly to medical institutions, as there is no need for soapy water in everyday life.
  • the above-mentioned prototype construction involves additional elements in the construction of a shower room or cabin, while the claimed device is quite flexible and can be applied as a regular shower component within a shower mixer, but with the additional function of washing the body with foam.
  • the technical problem addressed by the present invention is the lack of convenience and portability, as well as inefficient water and detergent consumption in existing shower devices.
  • the present invention is designed to solve the above-mentioned problems and enhance the effectiveness of showering, making it more convenient and economical for users.
  • the goal of the development of the claimed technical solution is to expand the functional capabilities of using a shower head, primarily by providing the ability to wash with ready foam, and in particular, to create additional convenience for people while bathing with significant savings in water, foaming liquid, and, most importantly, time.
  • this device not only delivers the usual water flow, but also dispenses rich foam upon pressing the button or turning the switch lever.
  • This device can be an efficient replacement for regular showerheads, as it has a similar appearance and can be easily attached to the shower hose or wall mount.
  • the technical task of the present invention is to create a shower head that is convenient, portable, ergonomic, and economical to use.
  • the task was to place a reservoir with a cleaning agent inside the shower head without significantly increasing its volume, using a piston or piston-spring system to deliver the cleaning agent into the water stream.
  • a mesh is installed in the spray head's diffuser to add the necessary amount of air to create foam.
  • the backflow valve is sealed and works at high pressures and temperatures.
  • the technical result achieved by implementing the present invention is uninterrupted and sufficiently long-term operation due to the convenience of placing all the elements for mixing water, air, and detergent in a single assembly inside the showerhead, providing convenience and portability.
  • Devices previously proposed for this purpose were too complex and expensive to be practical, and as a rule, they require installation by a plumber, making it difficult for the average person to purchase and install such a device in their shower.
  • the technical result achieved by implementing this invention is a significant increase in both the ease of switching between washing and rinsing modes, as well as the optimal use of the device, reducing labor intensity, maintaining working condition and uninterrupted operation, and with the presence of a spring combined with a piston - creating greater pressure inside the reservoir.
  • the technical result is achieved by mixing of water, cleaning liquid, and air to obtain foam (using a reservoir with a piston system, a valve for precise regulation, and a mesh) with such resistance at the outlet, at which their mixing was not possible only by mechanical means, without the use of electronic devices or other more complex and expensive solutions.
  • This increases the stability of the equipment compared to the operation of known showerheads.
  • the main advantage of the invention is the practicality of the showerhead's design. Firstly, it is easy to use for the user. Secondly, it saves water, cleaning solution, and time due to the unique mechanism of the showerhead's operation. Thirdly, it can use any liquid cleaning solution, including gels, and can operate at a minimum water pressure of 1 atmosphere. Refilling the showerhead with cleaning solution takes approximately 10 seconds and does not require any additional effort. This allows the showerhead to operate in "foam" mode continuously for 15-20 minutes, which is enough for bathing 5-10 times. Additionally, the price of the invention is relatively affordable compared to its analogs, which often use additional expensive components. The showerhead is also ergonomic and comfortable to hold without additional attachments.
  • the shower head includes a body with a handle and a water supply channel, as well as a nozzle in the form of a dividing head for dividing the flow into streams at the end of the shower head.
  • a reservoir for the cleaning agent Inside the body, there is a reservoir for the cleaning agent, a precise control valve with the ability to switch the amount of the cleaning agent, a channel for filling with gel from the outside, and a switch for switching between washing and rinsing modes.
  • Two check valves are located in the channel for filling with the cleaning agent and in the channel for supplying the ready-made mixture.
  • a tablet for mixing water and cleaning agent is located in the channel for supplying the foam on the way to the dividing head.
  • the dividing head in addition to its own water outlet nozzles, contains a smaller mesh for mixing the cleaning agent with water.
  • the reservoir contains two pistons of different diameters, rigidly connected to each other, and is made with the use of two volumes, each corresponding to the diameters of the large and small pistons.
  • the reservoir is of a single diameter, and instead of a large piston, a spring is used, to the moving end of which the small piston is attached.
  • the shower head includes a body 12 consisting of a handle 17, a dividing head 13, and a mode switch 2, with water being supplied from the shower hose through a water supply channel 1.
  • a reservoir 3 with large 4 and small 5 pistons rigidly fixed in it, and an opening 15 for water supply from the shower hose side.
  • the reservoir 3 fills with water, and then, as the pistons 4 and 5 move, the adjustable part of the reservoir 6, located on the side of the dividing head (13), gradually changes its volume to fill with detergent.
  • the precise gel control valve 7 is located outside the shower head in the upper part, and the nozzle 8 and mesh 9 are used to direct water or saturated foam to the consumer from the dividing head 13.
  • the shower head includes a body 12 consisting of a handle 17, a dividing head 13, and a mode switch 2, with water being supplied from the shower hose through a water supply channel 1. Inside the handle 17, there is a reservoir with a construction of spring 11 and a small piston 5. During operation, detergent is poured into the reservoir, and then, as the spring 11 and small piston 5 move, the adjustable part of the reservoir (6), located on the side of the dividing head (13), gradually changes its volume to fill with detergent.
  • the precise gel control valve (7) for regulating the amount of gel is located outside the shower head in the upper part, and the nozzle 8 and mesh 9 are used to direct water or saturated foam to the consumer from the dividing head 13.
  • a check valve 14 is used in the shower device to prevent changes in the direction of fluid flow in the technological system.
  • the mixing tablet 16 is located in the ready-to-use mixture supply channel 18.
  • the claimed technical solution can be implemented in two versions, and the operation of the showerhead device is shown below for the case when the reservoir is filled with shower gel.
  • water is supplied through the shower hose from the mixer to the water supply channel 1. Water then flows into the mode switch 2. Above the water supply channel 1 are reservoirs 3 and 6 with two pistons of different diameters, large 4 and small 5, and an opening 15 for water supply from the shower hose.
  • the reservoirs 3 and 6 are of different sizes, each designed for the movement of the corresponding piston diameter, and the difference in diameter between the rigidly coupled pistons 4 and 5 is 5% or more.
  • Reservoir 6 is refilled with gel through the gel filling channel 10, in which a check valve 14 is placed, using a special external dispenser.
  • Check valves 14 are used to prevent changes in the direction of the medium flow in the technological system of the showerhead and to achieve the tightness of the check valve, which operates under high pressures and in conditions of possible high temperature of the working medium, such as hot water.
  • the positive result is achieved through the proper positioning of all parts and the observance of the necessary dimensions. For example, if the mesh 9 has an incorrect cross-section or is too close to the sprayer (less than 0.5 mm), the result will be significantly worse. Additionally, this device has the advantage over others in that the agent in the reservoir is sufficient for multiple uses, and refilling the device is not difficult for the user.
  • the main difference from the piston variant is in the operation of the reservoir.
  • the entire space is occupied by reservoir 6, which in this case is filled with gel completely and does not contain separate parts.
  • the cleaning agent is pushed out of the reservoir 6 by the higher water pressure in the reservoir, which is obtained due to the different volumes of reservoirs 3.
  • a spring 11 is installed in the reservoir 6 with the gel, which will push the gel out to mix with water.
  • the advantage of this spring-piston version is the possibility of increasing the volume of the reservoir. The more gel is dispensed from the external dispenser, the more the spring 11 compresses, and the reservoir 6 can be filled completely. The peculiar feature of the spring's operation is that with its relaxation, the pressure of the gel going into the water decreases. Therefore, the precise gel control valve 7 plays a significant role in the spring-piston version.
  • the device operates as follows: water is supplied from the mixer hose to the water supply channel 1 and enters the water supply mode switch 2. Positioned above the water supply channel 1 is the reservoir 6 with small piston 5 and spring 11. Upon pressing the mode switch 2, the main water supply channel 1 is closed, and the additional ready-to-use mixture supply channel 18 is opened for the mixing of the liquid and soap agent. In the open channel, the piston 5 pushes the gel in the reservoir 6 with a higher pressure than the initial water pressure due to the pressure of the compressible spring 11. This pressure is necessary for the delivery and further mixing of the gel with water. The required proportion is regulated by the precise gel control valve 7, which has the function of controlling the amount of gel delivery.
  • the mixture flows through the ready-to-use mixture supply channel 18 and through mixing tablet 16 for better mixing, then enters nozzle 8 where, under pressure, it flows through the special mesh 9 with a particular cross-section, forming dense foam when mixed with air.
  • the reservoir 6 is refilled through gel filling channel 10 (which contains a check valve 14) using a special dispenser, as in the piston variant.
  • the user gets the opportunity to obtain foam for 20 minutes continuously with an economical use of the cleaning agent.
  • foam will be formed from one filling of the reservoir for 10 minutes. If a very thick foam is needed, the washing stage will take 5 minutes, which is sufficient for comfortable showering, as one minute is usually enough for high-quality soaping of a person. Then, the user switches the shower using mode switch 2 to the flow mode, rinses off the foam, and the washing process is complete.
  • the claimed design is characterized by its portability and universality.
  • the area of application of the claimed design is significantly wider than that of known analogs due to its compactness and simplicity of both manufacturing and use.
