Description

Technical Field

[0001] The present invention relates to a sanitary insert, which is designed to be mounted on a water outlet of a fitting, wherein the sanitary insert comprises a base body and a movable operating part in contact with the base body, wherein the base body has a switching mechanism, wherein the operating part can operate the switching mechanism using a control element. Such sanitary inserts are widely used in practice.

[0002] The invention also relates to the use of a pivotable operating element. Background Art

[0003] Such components are known and can be used, for example, to switch between a low flow rate and a higher flow rate or between different jet shapes or to switch off or connect a water jet.

[0004] Furthermore, such components are used to meet legal standards or regulations regarding water conservation at fittings.

[0005] It has been common in the prior art to convert an axial actuating movement of the actuating element into an axial actuating movement of the switching mechanism or to convert a lateral actuating movement of the actuating element into an axial actuating movement of the switching mechanism.

[0006] WO 2020 / 164342 A1 discloses a sanitary insert having a water outlet structure with a dome-shaped protrusion. In this case, when a lateral load is applied, the operating part slides on the contact surface of the base body and moves the protrusion relative to the control element. However, the disadvantage of this solution is that a large space requirement is required and the lateral load requires a relatively large amount of force from the user. Therefore, it may be difficult to operate the sanitary insert in sanitary installations with narrow spatial conditions.

[0007] CN107289184A discloses a sanitary insert in which the water outlet structure has a triangular shaped portion into which the control element can be guided and deflected. The lateral loading of the operating element is achieved by forming a radially circumferential recess on the base body into which the operating element can be pushed. The disadvantage of this solution is that it again requires a large amount of space. This significantly limits the structural design possibilities of the sanitary fitting. Summary of the invention

[0008] The object of the present invention is to provide a sanitary insert which eliminates the disadvantages of the prior art. In particular, a sanitary insert should be provided which should be easy to handle and should be replaceable or maintainable without tools such as screwdrivers. The operability is improved, for example, so that the user can screw in and out the sanitary insert using only his hands. The object is achieved by the features of the independent claim. Advantageous embodiments are described in the dependent claims.

[0009] It should be noted that the features listed individually in the dependent claims can be combined with each other in any technically meaningful way and define other designs of the present invention. In addition, the features given in the claims are further described and elaborated in detail in the specification, wherein other advantageous designs of the present invention are shown.

[0010] To achieve the stated object, the invention proposes the features of claim 1. In particular, according to the invention, in a sanitary insert of the type mentioned at the outset, it is proposed to achieve the stated object that the actuating element forms a bearing which defines a deflection point with respect to a lateral load, wherein an operative connection to the control element is provided which converts the lateral load into an axial movement. The sanitary insert can thus be used in confined fitting situations or in small available spaces and can be easily actuated by the user.

[0011] In order to achieve the proposed object, the invention also (alternatively or additionally) proposes the features of claim 2. In particular, according to the invention, in a sanitary insert of the type mentioned at the outset, in order to achieve the proposed object, it is proposed that the operating part is connected to the control element via two mutually contacting curved surfaces. It can be provided that in the rest position the operating part is arranged coaxially with the base body and that, additionally or alternatively, in one or the rest position the operating part contacts the control element at the point of the minimum force transmission ratio. Thus, the force transmission ratio or force-travel conversion ratio can be adjusted by the design of the two contacting curved surfaces. This can, for example, involve the ratio of the two radii of curvature of the contacting curved surfaces to each other.

[0012] Here, the deflection point is a point around which the operating part rotates. This is different from a pure translational movement, such as an axial movement or a radial movement. Preferably, this rotation is a rotation around a horizontal axis or an axis transverse to, in particular perpendicular to, the flow direction of the insert.

[0013] In an advantageous embodiment, provision can be made for a coupling function to be provided, which produces a rotationally fixed connection between the actuating element and the base body. The actuating element and the base body can thus be connected to one another and the user can manually and tool-free unscrew the sanitary insert from the fitting by rotating it. The coupling function is preferably activated when the actuating element is actuated, in particular when the actuating element is lifted or pivoted relative to the base body.

[0014] In an advantageous embodiment, it can be provided that the coupling functions are oriented identically with respect to the switching mechanism. Identical orientation can mean that the switching mechanism and the coupling functions act in the same and / or opposite directions. Thus, the functionality of the actuating element can be replicated, in particular in this case both the switching mechanism related to the throughflow and the coupling functions related to the installation and removal of the sanitary insert can be easily combined.

[0015] In an advantageous design, it can be provided that the coupling function comprises a coupling element and a mating coupling element that act together. Thus, the coupling function can be provided reliably and simply. It is also conceivable and achievable to form a plurality of coupling elements. It is also conceivable and achievable to form a plurality of mating coupling elements. The number of coupling elements and mating coupling elements can be determined during manufacture and naturally influences the maximum angle that must be rotated, with which the coupling function is activated. The coupling function is activated when the coupling element and the mating coupling element are in contact.

[0016] In an advantageous design, it can be provided that the coupling element is formed on the operating part. Thus, a mechanically stable and manufacturing-technically advantageous arrangement can be provided. As already explained above, a plurality of coupling elements can also be formed on the operating part.

[0017] In an advantageous design, it can be provided that the mating coupling element is formed on the base body. This can provide a mechanically stable and manufacturing-technically advantageous arrangement. As already explained above, a plurality of mating coupling elements can be formed on the base body. The mating coupling element can be formed, for example, as a wall or a plurality of walls. A wall generally describes a structure that can separate two partial regions from each other.

[0018] In an advantageous embodiment, it can be provided that the coupling element has a reversing unit. Additionally or alternatively, it can be provided that the mating coupling element has a mating reversing unit. Thus, when the coupling element and the mating coupling element meet each other head-on, the two components can be guided past each other gently and the coupling function is simplified overall. This is advantageous, for example, when the coupling element and the mating coupling element meet each other head-on and the coupling function cannot therefore yet be activated.

[0019] In an advantageous embodiment, it can be provided that the switching unit and the mating switching unit have mirror symmetry. Preferably, the axis of mirror symmetry is formed transversely to, in particular orthogonally to, the flow direction. As a result, the coupling element and the mating coupling element can be guided past each other in a friction-effective manner. Mirror symmetry can mean that the properties, for example geometric properties, of the switching unit and the mating switching unit are mirror-symmetrical about the axis of mirror symmetry. This can generally contribute to the operating comfort of the user.

[0020] In an advantageous embodiment, it can be provided that the commutation unit has at least one curved and / or flat surface. Additionally or alternatively, it can be provided that the mating commutation unit has at least one further curved and / or flat surface. Thus, the commutation unit and the mating commutation unit can ensure that the coupling element and the mating coupling element are guided past each other in a friction-efficient manner. In particular, the operation by the user can also be simplified overall here, since he does not have to expend much force to achieve the coupling function. The terms "flat" and "curved" are commonly used in mathematics.

[0021] In an advantageous design, it can be provided that the control element comprises a push rod and a ball component. The push rod is preferably configured as a cylinder. Therefore, a simple structural form of the control element can be provided. The push rod and the ball component can be configured integrally with each other, for example.

[0022] The push rod can be in operative connection with the switching member, while the ball element can be in constant contact with the actuating element and in particular with the water outlet structure.

[0023] In an advantageous embodiment, it can be provided that a flow regulator is connected upstream of the base body on the inflow side. Thus, the flow pressure can be adjusted or predetermined as a function of the flow rate. This improves the operating properties of the sanitary insert.

[0024] In an advantageous embodiment, it can be provided that the decomposer unit is arranged between the base body and the actuating element. The decomposer unit is preferably connected downstream of the switching mechanism on the flow side. Thus, a vortex of the water jet can be achieved, which advantageously influences the jet shape.

[0025] In an advantageous design, it can be provided that the operating component has an outer sleeve. It can also be provided that the operating component includes an inner sleeve. It can be provided that the outer sleeve and the inner sleeve are connected to each other via a web, and that a ventilation channel is additionally or alternatively configured between the outer sleeve and the inner sleeve. Thus, a mechanically stable shape of the operating component and / or a mixing of air and water jets can be achieved. This advantageously influences the jet morphology.

[0026] The coupling element is preferably formed on the inner sleeve. The coupling element can alternatively or additionally be arranged on the outer sleeve.

[0027] In an advantageous embodiment, it can be provided that the operating element is pivotable, thereby increasing the operating comfort for the user and reducing the space requirement of the sanitary insert, thereby also making it easy to direct the discharged water jet in different directions.

[0028] In an advantageous embodiment, it can be provided that the resolver unit has a channel in which the push rod rests in a sealing manner. This provides a guide device which can axially guide the push rod.

[0029] The term “axial” is used in the context of the invention for the flow direction; “radial” for this purpose is a direction which is configured orthogonally to the flow direction.

[0030] In an advantageous design, it can be provided that the inner sleeve has a water outlet structure, so that a uniform and visually pleasing water jet can be provided.

[0031] In an advantageous design, it can be provided that the diameters of the push rod and the ball component are not the same. Thus, a structural alternative can be provided. Thus, a sliding surface that is not limited by the push rod can be provided.

[0032] In an advantageous embodiment, it can be provided that the push rod and the ball part have the same diameter or that the push rod has a larger diameter than the ball part. Thus, a structural alternative can be provided. It is therefore also possible to insert the push rod forward together with the head part by introducing it into a guide opening, for example into the already mentioned channel for axially guiding the push rod. This can make assembly easier.

[0033] In an advantageous embodiment, it can be provided that the diameter of the push rod is as large as the inner diameter of the channel. Thus, a guide device can be provided. Preferably, the push rod is located on the channel in a sealing manner.

[0034] The ball component can be configured as a spheroid, a hemisphere or a sphere or an ellipsoid segment, for example. The ball component can alternatively be configured as a rounded portion. Even if there is no lower limit to the usable radius of curvature, it can be said that in many cases the greater the radius of curvature at the ball component, the better the sliding.

[0035] In an advantageous design, it can be provided that the water outlet structure has a curved surface. The curved surface is preferably configured in a bowl shape. It can be provided that the control element can slide on the curved surface. Therefore, an operative connection between the control element and the operating component (to which the water outlet structure belongs) can be realized in a simple structural manner.

[0036] In an advantageous embodiment, it can be provided that the water outlet structure has a projection, in particular the width of the projection is equal to the width of the water outlet structure. The width of the water outlet structure and the width of the projection are measured in the flow direction. The projection can be advantageous when operating the operating component, in particular when operating the switching mechanism and the coupling function.

[0037] In an advantageous design, it can be provided that the switching mechanism is a ballpoint pen mechanism or a pilot valve-main valve mechanism. The switching mechanism can alternatively also be constructed as a servo switch mechanism (Servo-On-Off-Mechanik) or as a mechanism as known from WO2018 / 050285A1.

[0038] In an advantageous embodiment, it can be provided that the force-travel ratio of the control element is a function of the deflection angle of the actuating part from the rest position. Thus, the force-travel ratio of the control element can be adjusted by the deflection angle of the actuating part. This has a positive effect on the user-friendliness of the sanitary insert.

[0039] The rest position is the position of the sanitary insert in which the main body and the actuating element have coinciding main axes or are arranged coaxially.

[0040] In an advantageous embodiment, it can be provided that the inwardly projecting projection, for example the projection already mentioned, forms a recess into which the mating projection of the base body engages. Thus, the base body and the actuating element are structurally connected to one another in a simple manner.

[0041] In an advantageous embodiment, it can be provided that the engagement projection is arranged between the inner sleeve and the outer sleeve. Thus, a mechanically stable arrangement is provided.

[0042] In an advantageous embodiment, it can be provided that at least a portion of the inwardly projecting projection of the actuating element disengages from the outwardly projecting mating projection of the base body when the actuating element is laterally loaded. Thus, a deflection point can be provided in a simple structural manner and an arrangement that can be used well in confined space conditions can be provided overall.

[0043] The invention recognizes that the design of the deflection point and the type of actuation of the sanitary insert have a positive influence on the force or effort required by the user relative to the existing water pressure.

[0044] In an advantageous embodiment, it can be provided that, at maximum lateral loading of the actuating element, a part of the actuating element contacts the base body at the contact point. Thus, a simple structural design of the base body can be provided and the maximum lateral loading can be limited and adjusted.

[0045] In an advantageous embodiment, it can be provided that the actuating element can be loaded not only laterally but also axially. This is achieved primarily by the shaping of the actuating element and the control element. The formation of the lateral loading and the possibility of axial lifting are advantageous in terms of the user-friendliness of the sanitary insert.

[0046] In an advantageous embodiment, it can be provided that the force-travel ratio of the control element is constant when the actuating element is lifted axially. During axial lifting, the actuating element is only lifted axially, wherein the control element is also lifted uniformly and can thus actuate the switching mechanism. The force-travel ratio is thus constant and is achieved by the design of the actuating element and the control element. A certain axial lift of the actuating element is directly transferred to the same axial distance of the control element.

[0047] In an advantageous design, it can be provided that the center of curvature of the two mutually contacting curved surfaces is located within the control element. The two mutually contacting curved surfaces are provided on the one hand by the curved surface (also referred to as the mating surface) of the ball component of the control element, and on the other hand by the curved surface on the water outlet structure of the operating component. Therefore, it can be achieved by simple structural measures that the control element can realize both axial loading and lateral loading.

[0048] The advantage here is that a lateral load which leads to a rotational movement of the actuating element about the deflection point requires less force from the user than an axial lift, which can improve the operating comfort of the sanitary insert.

[0049] In an advantageous embodiment, it can be provided that the control element is in operative connection with the switching mechanism. Thus, the switching mechanism can be switched by the control element in a simple structural manner.

[0050] In an advantageous design, it can be provided that the curved surface on the water outlet structure has a through opening. Thus, a uniform water jet can be provided, and the water jet also has an aesthetically pleasing jet shape.

[0051] In addition, the operating part comprises an inner sleeve with a water outlet structure. The inner sleeve also has a mixing chamber in which the water jet is mixed with air, wherein the air is sucked in through a ventilation channel. The ventilation channel is arranged between the inner sleeve and the outer sleeve.

[0052] In an advantageous design, it can be provided that the water outlet structure has a through opening in the radial direction, and the through opening has an opening cross-sectional area that increases outwards. Thus, a visually advantageous jet shape can be achieved and an arrangement structure that provides a uniform water jet is provided.

[0053] In an advantageous embodiment, it can be provided that the base body has an external thread and an additional or alternative sealing element surrounding the outside. The sealing element is preferably designed as a sealing ring. The base body can thus be mechanically simply fastened to the sanitary fitting and additionally provides a sealing function that prevents water from flowing out between the sanitary fitting and the base body.

[0054] In an advantageous design, it can be provided that the force-stroke conversion ratio of the control element is a function of the deflection angle of the operating part from the rest position, in particular wherein the function is (preferably strictly) monotonically rising. Therefore, the force-stroke conversion ratio can be adjusted by means of the curved surface (also referred to as the mating surface) on the ball part of the control element. In the case of a small deflection angle, the curved surface at the water outlet structure is relatively flat, which corresponds to a small force-stroke conversion ratio. When the deflection angle is large, the curved surface at the water outlet structure has steeper sides, which corresponds to a larger force-stroke conversion ratio. The force applied by the control element to the switching mechanism therefore increases with the deflection angle of the operating part. This is advantageous for the user-friendliness and quality of operation of the sanitary insert.

[0055] In an advantageous embodiment, it can be provided that the operating part is suspended on the base body by means of a snap connection. Preferably, the snap connection is configured to be non-detachable. Thus, a simple structural and mechanically stable construction can be provided, which connects the operating part and the base body to each other.

[0056] The base body has an outwardly projecting mating projection, on which the inwardly projecting projection of the actuating component acts. The base body also has a circumferential groove, into which the inner sleeve of the actuating component projects when side loads occur. The mating coupling element can be formed as a wall in the groove.

[0057] In an advantageous embodiment, it can be provided that the snap connection has a ramp and, in addition or alternatively, a projection which is limited in the circumferential direction. This allows lateral loading and, therefore, rotation about a deflection point. The ramp can be used to ensure that the inwardly projecting projection of the actuating element can be reliably guided past the base body in the event of lateral loading.

[0058] To achieve the above-mentioned object, the invention provides the features of the independent parallel claim 27 for an application. In particular, to achieve the object, the invention provides in one application that a pivotable actuating element is used to convert a laterally directed actuating force into an axially directed actuating force in order to actuate a switching mechanism of a sanitary insert according to one of the features. This makes it possible to provide simplified actuation.

[0059] To achieve the above-mentioned object, the invention provides the features of the independent parallel claim 28 for an application. In particular, therefore, to achieve the object, the invention provides in one application that the pivotable actuating element is designed to redirect a water jet emerging from a sanitary insert according to one of the features. This can increase the operating comfort and the operating quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0080] In the following description of various exemplary embodiments of the present invention, functionally identical elements are provided with identical reference numerals even in the case of different designs or shapes.

[0081] For the sake of clarity, not all reference numerals are provided in the drawings, although an element may well appear in the drawings. However, the same reference numerals denote functionally and / or structurally identical components and functional units.

[0082] Figure 1 The sanitary insert 1 is shown in a sectional view in an initial position. The sanitary insert 1 is inserted into a fitting 2 which has a water outlet 3. The flow direction is not shown in the figure, but runs from top to bottom.

[0083] The sanitary insert 1 comprises a main body 4 and an actuating element 5 which is movably arranged and contacts the main body 4 .

[0084] The base body 4 has a switching mechanism 6, which is configured as a switching mechanism 6 with a throttle body 7 in the current figure. Other switching mechanisms 6, such as a ballpoint pen mechanism or a pilot valve-main valve mechanism, can also be used and applied. The throttle body 7 has a cap-shaped forming part, which consists of a cylindrical part and a surrounding edge. The throttle body 7 can be introduced into a matching cap structure 8. In the present invention, Figure 1 In the embodiment, the throttle body 7 is spaced apart from the matching cap structure 8 in the axial direction and closes the through-opening belonging to the resolver unit 9 .

[0085] The resolver unit 9 is arranged between the main body 4 and the actuating element 5 .

[0086] The operating part 5 can operate and switch the switching mechanism 6 with the control element 10. In this figure, the control element 10 is in contact with the throttle body 7. The operating part 5 has a protrusion 11 extending inwardly, on which a support 12 is configured. The protrusion 11 can be surrounded on the circumferential side or partially surrounded on the circumferential side. The support 12 defines a deflection point 13 in terms of lateral loading, wherein an operative connection with the control element 10 is designed. The control element 10 can convert the lateral loading into an axial movement. The control element 10 is in operative connection with the switching mechanism 6.

[0087] The sanitary insert 1 provides a coupling function 37 which produces a rotationally fixed connection between the actuating element 5 and the base body 4. The coupling function 37 can be activated and deactivated. Figure 1 , the coupling function 37 is present but not activated, since both the base body 4 and the actuating element 5 are in the starting position. The coupling function 37 is oriented identically to the switching member 6 .

[0088] The coupling function 37 comprises cooperating coupling elements 38 ( Fig.16 ) and mating coupling element 39 ( Fig.15 ).exist Figure 1 In the embodiment of the present invention, the coupling element 38 and the mating coupling element 39 are present, but are not visible due to the sectional view. The coupling element 38 is formed on the actuating part 5. The mating coupling element 39 is formed on the base body 4.

[0089] The operating part 5 comprises an inner sleeve 14 and an outer sleeve 15, which are connected to each other by a web 16. The inner sleeve 14 has a mixing chamber 33 on the inflow side, in which the water jet can be mixed with air. The air is sucked through the ventilation channel 17 between the inner sleeve 14 and the outer sleeve 15. On the outflow side, the inner sleeve 14 has a water outlet structure 18. The water outlet structure 18 has an arched surface 19 in the center, in which the control element 10 is located and can slide. The arched surface 19 is configured as a bowl. The control element 10 has an arched matching surface 20, which contacts the arched surface 19.

[0090] Figure 1 The rest position or initial position is shown, in which the actuating element 5 is arranged coaxially with respect to the base body 4. In the rest position, the actuating element 5 contacts the control element 10 at the point of the minimum force transmission ratio.

[0091] The control element 10 comprises a push rod 21 and a ball component 22. The push rod 21 is preferably cylindrical.

[0092] The push rod 21 is guided axially through a channel 34 and rests sealingly against it, wherein the channel 34 belongs to the resolver unit 9 . The ball element 22 is in permanent contact with the curved surface 19 belonging to the water outlet structure 18 .

[0093] The flow regulator 23 is connected on the inflow side upstream of the base body 4. The flow regulator 23 has a prescreen 24 which is connected on the inflow side upstream of a sealing element 25, for example a sealing ring.

[0094] The inwardly projecting projection 11 forms a recess 26 into which a mating projection 27 of the base body 4 engages. The mating projection 27 is arranged radially between the inner sleeve 14 and the outer sleeve 15.

[0095] The center of curvature of the two contacting curved surfaces 19, 20 lies within the control element 10. By technically configuring the center of curvature and the radius of curvature of the curved surfaces 19, 20, the force-travel conversion ratio can be adjusted and the user-friendliness of the sanitary insert 1 can be improved.

[0096] The actuating element 5 is suspended on the base body 4 by means of a snap connection 28. The snap connection 28 is preferably designed to be non-detachable.

[0097] The snap connection 28 has a start-up bevel 29 and a mating projection 27 which is limited in the circumferential direction.

[0098] The base body 4 has an external thread 36 by means of which it is screwed onto the fitting 2 . The sealing element 30 surrounding the outside ensures that water cannot flow between the fitting 2 and the base body 4 .

[0099] It may also be mentioned that the base body 4 has a circumferential groove 31 .

[0100] Figure 2 The sanitary insert 1 is shown in section in the normal position with the inactive throttle body 7 .

[0101] exist Figures 2 to 5 In, reference Figure 1 For the sake of clarity and to avoid redundancy, the elements and reference numerals in Figures 2 to 5 Not all elements are provided with reference numerals.

[0102] Here, the throttle body 7 is introduced into the matching cap structure 8 and releases the through opening of the decomposer unit 9. The throttle body 7 is pressed into the matching cap structure 8 due to the existing water pressure. When the water flow is cut off, the throttle body 7 can return to the initial position again (see Figure 1 ) and blocks the through opening of the decomposer unit 9. Figure 2 The components and Figure 1 , and therefore are not provided with reference numerals.

[0103] Figure 3 The sanitary insert 1 is shown in a sectional view in the axially actuated position. In this case, the actuating part 5 is lifted axially relative to the base body 4, wherein the contact between the inwardly projecting projection 11 and the outwardly projecting mating projection 27 is released. The actuation direction is indicated by the arrow.

[0104] During axial actuation, the force-travel conversion ratio of the control element 10 is constant. This is achieved by converting the lift of the actuating part 5 directly into a lift of the control element 10. In this case, the user only has to exert a force corresponding to the weight of the actuating part 5 and the control element 10. The length of the push rod 21 must be dimensioned so that the push rod 21 can be guided through the channel 34 and the throttle body 7 can be introduced into the matching cap structure 8.

[0105] Figure 4 The sanitary insert 1 is shown in a sectional view in a lateral actuation position. A deflection point 13 is defined on the inwardly projecting projection 11, wherein the actuating element 5 and the base body 4 are arranged eccentrically. A part of the inner sleeve 14 here projects into the circumferential groove 31, while a part of the outer sleeve 15 contacts the base body 4 at the contact point 32 when the actuating element 5 is subjected to maximum lateral loading. The dimensions of the curved surface 19 at the water outlet structure 18 and the control element 10 are coordinated in such a way that the throttle body 7 can be introduced into the matching cap structure 8. The force-travel conversion ratio of the control element 10 is a function of the deflection angle of the actuating element 5 from the rest position, wherein the force-travel conversion ratio of the control element 10 increases strictly monotonically with respect to the deflection angle of the actuating element from the rest position. At small deflection angles from the rest position, the force-travel conversion is relatively small, while at larger deflection angles, the force-travel conversion ratio is also larger. It is advantageous here that the force-travel conversion ratio can be adjusted by selecting or designing the curved surfaces 19 , 20 and the operating comfort for the user can be improved.

[0106] The steering direction is indicated by the arrow.

[0107] The lateral loading of the actuating element 5 is advantageous in particular in confined space situations and allows a large number of different fittings 2 to be used.

[0108] Figure 5 The sectional view shows a sanitary insert 1 with any desired switching mechanism 6. The switching mechanism can be, for example, a ballpoint pen mechanism or a pilot valve-main valve mechanism. As shown in the previous figures, the switching mechanism 6 can also be designed as a switching mechanism 6 with a throttle body 7. Other switching mechanisms 6 can also be used here.

[0109] The sanitary insert 1 can be actuated both axially and laterally.

[0110] Figure 6The sanitary insert 1 is shown in a perspective view from above. The prescreen 24 , the external thread 36 and the actuating element 5 can be seen here.

[0111] Figure 7 The sanitary insert 1 is shown in a perspective view from below. The external thread 36, the actuating element 5, the web 16 and the water outlet structure 18 are visible. Figure 7 A contact point 32 is shown which is formed on the base body 4 .

[0112] Figure 8 The operating part 5 is shown in a sectional view. The inner sleeve 14 and the outer sleeve 15 are visible, wherein the two are connected to each other via a web 16. A ventilation channel 17 is formed between the webs 16. The inwardly projecting projection 11 is partially formed around the circumferential side. The curved surface 19 at the water outlet structure 18 has a through opening. In addition, the water outlet structure 18 usually has a through opening 35 in the radial direction, and the through opening 35 has an opening cross-sectional area that increases outward.

[0113] Fig. 9 An embodiment of a control element 10 is shown.

[0114] Figures 1 to 5 The control element 10 in the embodiment is designed in such a way that the diameter of the push rod 21 is smaller than the diameter of the ball part 22. The diameter of the push rod 21 is equal to the inner diameter of the channel 34 of the decomposer unit 9. This results in the control element 10 having to be installed from below, that is, opposite to the flow direction and opposite to gravity (for example during assembly). This can make assembly difficult. For this reason, Figures 9 to 12 An alternative embodiment of the control element 10 is shown.

[0115] Fig. 9 The control element 10 in the embodiment of the present invention has a preferably cylindrical push rod 21 and a ball part 22, wherein the diameter of the push rod 21 is the same as the diameter of the ball part 22. The ball part 22 is designed to be hemispherical here. The diameters of the push rod 21 and the ball part 22 are coordinated with the inner diameter of the channel 34 and are the same size as the inner diameter. Therefore, the control element 10 can be installed in the sanitary insert 1 from above, that is, in the direction of the flow direction and in the direction of gravity, and thus the assembly is simplified. The push rod 21 and the ball part 22 are designed as a single piece.

[0116] Fig.10Another embodiment of the control element 10 is shown. The control element 10 again has a push rod 21 and a ball part 22. The ball part 22 is designed as a rounded part or a spherical segment. The diameter of the rounded part or the spherical segment is the same as the diameter of the push rod 21. The diameter of the push rod 21 is coordinated and identical to the inner diameter of the channel 34, which is part of the decomposer unit 9. The push rod 21 can be guided through the channel 34 preferably in a sealed manner. The push rod 21 and the ball part 22 are designed as a single piece.

[0117] Fig.11 Another embodiment of the control element 10 is shown. The control element 10 again has a push rod 21 and a ball component 22. The push rod 21 and the ball component 22 are constructed in two parts, wherein the ball component 22 is constructed as a ball. The diameter of the ball component 22 constructed as a ball is smaller than the diameter of the push rod 21. The diameter of the push rod 21 is coordinated with the inner diameter of the channel 34 and is the same as it. The ball can be rotated like a ball in the tip of a ballpoint pen.

[0118] Fig.12 Show Fig.11 1 is a cross-sectional view of a control element 10. The ball component 22 designed as a ball is shown in black filling, while the push rod 21 is shown in hatching.

[0119] Fig.13 The figure shows a partial section through the sanitary insert 1 in the starting position. The lower part of the sanitary insert 1 is shown in section, while the upper part is not cut away and also shows the external thread 36. The coupling function 37 is Fig.13 The water outlet structure 18 has a projection 44, wherein the width 45 of the projection 44 is equal to the width 46 of the water outlet structure 18. The widths 45, 46 are measured in the flow direction.

[0120] Fig.14 Show Fig.13 1 shows a partial sectional view of the sanitary insert 1 in the actuation position. In the actuation position, the user has actuated the actuation element 5 and thus the switching mechanism 6, and the coupling function 37 is also activated.

[0121] Fig.15 The base body 4 is shown in a perspective view in the disassembled state. A mating coupling element 39 is formed on the base body 4. The mating coupling element 39 is shown as a wall in the groove 31. The mating coupling element 39 has a mating switching unit 41.

[0122] Fig.16 The operating part 5 is shown in a perspective view. The coupling element 38 is formed on the operating part 5. Fig.16In the embodiment, the coupling element 38 is formed on the inner sleeve 14. Of course, multiple coupling elements 38 can also be formed, for example, to improve the user's operating pleasure. The coupling element 38 has a reversing unit 40. The function of the reversing unit 40 is to cooperate with the coupling element 39 ( Fig.15 ) to reverse the coupling element 38. This may be necessary, for example, in a head-on encounter between the coupling element 38 and the mating coupling element 39.

[0123] Cooperate with reversing unit 41( Fig.15 ) is to make the mating coupling element 39 ( Fig.15 )Reversal.

[0124] exist Fig.15 and Fig.16 In the embodiment, the reversing unit 40 and the mating reversing unit 41 have flat surfaces 42, 43. In alternative and additional embodiments, the surfaces 42, 43 can be curved. The shape of the surface can be related to the friction and the necessary force expenditure of the user and therefore in particular to the operating comfort of the user.

[0125] Fig.17 The diagram shows a principle diagram of the mode of operation of the coupling function 37, the switching unit 40 and the counter-switching unit 41. In this case, the actuating element 5 is actuated from left to right.

[0126] The first figure from the left shows a starting position in which the coupling function 37 is present but not activated. The coupling element 38 and the counter coupling element 39 are visible and are spaced apart from each other.

[0127] In the second figure from the left, the coupling element 38 and the matching coupling element 39 meet each other due to the user's operation of the operating component 5. The reversing unit 40 formed on the coupling element 38 and the matching reversing unit 41 formed on the matching coupling element 39 interact with each other and prevent the front faces of the coupling element 38 and the matching coupling element 39 from meeting.

[0128] In the third figure from the left, the coupling element 38 and the counter coupling element 39 are completely guided past each other. In the change of direction between the first figure from the left and the third figure from the left, a small relative rotation occurs between the base body 4 and the actuating part 5.

[0129] In the fourth figure from the left, the end position in which the coupling function 37 is activated is now reached. The user can now unscrew the sanitary insert 1 from the fitting 2 and screw it back in again by turning the actuating element 5 which is now rotationally fixedly connected to the base body 4. This can facilitate maintenance of the sanitary insert 1 or replacement of the sanitary insert 1.

[0130] The commutation unit 40 and the mating commutation unit 41 have mirror symmetry. This may mean that the commutation unit 40 and the mating commutation unit 41 are mirror symmetric about an axis.

[0131] In a sanitary insert 1, it is proposed that the sanitary insert is designed to be mounted on a water outlet 3 of a fitting 2, and that the sanitary insert comprises a base body 4 and a movable operating part 5 in contact with the base body, wherein the base body 4 has a switching mechanism 6, wherein the operating part 5 can be operated by a control element 10, wherein the operating part 5 preferably forms a support 12 on an inwardly protruding protrusion 11, which defines a deflection point 13 with respect to a lateral load, wherein an operative connection with the control element 10 is provided, and the control element converts the lateral load into an axial movement.
