Description

Quick Switch and Corresponding Use

technical field

The present invention relates to a quick switch for a sanitary device.

State of the art

To save the water, many people take a shower while bathing. In the prior art, a sanitary device in the form of a shower device has a water outlet device, which can in particular be either a sprinkler head attached to the wall or a shower head in the form of a lotus that can be used manually and is movable by a user. In addition, the shower device also has a switch, which is usually arranged separately from the water outlet device on the wall and can control the water outlet device, i. H . whether the water is sprayed or not.

However, many people close their eyes when showering to avoid water getting into their eyes, which could cause eye discomfort. Therefore, the user only needs to look for the position of the switch with both hands to open or close the water outlet device without being able to see the position of the switch. Not only is it inconvenient to use, but there is a risk of the user being burned by accidentally touching a hot and cold water control device.

Sanitary devices are known, for example, in the form of shower devices, washbasins, fittings, bathtubs and/or bathing devices.

Disclosure of the Invention In view of the technical disadvantages and shortcomings mentioned above, the present invention provides a high-speed switch that can be placed between a water outlet device and a water pipe and switch a flow of water. As a result, the user can control the opening and/or closing and/or other switching states of the water outlet device by pushing the water outlet device directly.

In order to achieve the foregoing object of the present invention, the technical measure of the present invention is to provide a quick switch for a sanitary device, which is designed to connect a water source and a water outlet device, the quick switch comprising: a tubular body comprising a water inlet send, which is designed for connection to the water source, a water outlet send, which is designed for connection to the water outlet device, wherein the water outlet end and the water inlet end can come closer to or away from each other, and a pressing part, which is arranged at the water outlet end and is moved with the water outlet end ; and a valve body which is arranged in the tubular body and realizes at least two fluidic switching states between the water inlet end and the water outlet end, for example the water inlet end and the water outlet end can be blocked or connected, the valve body comprising a switching element, the pressed part of the tubular body being pressed by the Approaching the water inlet end and the water outlet end to each other can press the switching element of the valve body, whereby the valve body is switched to either one of the at least two fluidic switching states between the water inlet end and adjust the water outlet end, in particular to block a connection between the water inlet end and the water outlet end or to connect the water inlet end and the water outlet end.

The advantage of the present invention is that the valve body is arranged in the pipe body and can block or connect the water inlet end and the water outlet end of the pipe body; that the water inlet end and the water outlet end of the pipe body can come closer to each other or move away from each other; and that the pressing part is formed at the water outlet end so that when the water inlet end and the water outlet end come closer, the pressing part can thereby press the switching element of the valve body and thereby the water inlet end and the water outlet end of the pipe body are blocked or connected through the valve body. Thus, the quick switch for a shower device of the present invention is connected between the water source (e.g. a water pipe) and the water outlet device (e.g. sprinkler head), which allows the user to slide the water outlet device directly so that the water inlet end and the water outlet end of the Tubular body come closer to each other. This blocks or connects the water inlet end and the water outlet end of the pipe body and in turn controls whether the water from the water source flows through the present invention to the water outlet means. In other words, the user can control whether the shower device sprays the water or not by directly pushing the water outlet device, so that he can realize quick switching even with his eyes closed, without otherwise looking for the switch arranged on the wall in the dark and even accidentally touching the hot and cold water controls. In an advantageous embodiment it can be provided that a blocking fluidic switching state of the at least two fluidic switching states blocks a water flow between the water inlet end and the water outlet end. It is thus possible to switch off a water flow by pressing on the water inlet end and/or on the water outlet end.

In an advantageous configuration it can be provided that a connecting fluidic switching state of the at least two fluidic switching states releases a water flow between the water inlet end and the water outlet end. A fluidic connection can thus be established.

In an advantageous embodiment, it can be provided that a variable compensating volume is formed downstream of the valve body. Thus, a volume of water that is displaced during a shift can be stored temporarily. To this end, it is favorable if the compensating volume communicates fluidly with the outlet end.

It can be provided that the compensating volume is at least as large as a volume of water displaced when the switching state changes. It is thus possible to prevent an actuation movement from being hindered by incompressible water.

It can also be provided that the compensating volume has a piston. A variable volume can thus be made available in a simple manner.

It can be provided here that the piston is acted upon by a restoring element. In this way, an automatic emptying of the compensating volume can be achieved in the event of a pressure drop. Alternatively or additionally, it can be provided that the piston is open at the rear against an ambient pressure and/or is acted upon by a compressible fluid. A compensating movement or an increase in volume can therefore be carried out on the basis of the displacement already mentioned.

Further, the quick switch can be provided for a sanitary device, wherein the pipe body further comprises: a first pipe, wherein the water inlet end is formed at an end of the first pipe, and wherein the valve body is arranged in the first pipe; and a second tube, wherein the water outlet end is formed at an end of the second tube, and the second tube is fitted movably around the first tube so that the water outlet end and the water inlet end can come closer to or away from each other.

Furthermore, the high-speed switch can be provided for a sanitary device, with an internal thread being formed on an inner wall surface of the water inlet end; and a male thread is formed on an outer wall surface of the water outlet end.

Further, the quick switch can be provided for a sanitary device, the valve body further comprising: a chamber base comprising an outer chamber connected to the water inlet end, an inner chamber connected to the outer chamber, and a connecting passage connected to the inner chamber and connected to the water outlet end, wherein the water from the water source can only flow sequentially through the water inlet, the outer chamber, the inner chamber and the connecting channel to the water outlet end; and a blocking element which is flexible and selectively abuts the chamber base and blocks the outer chamber and the inner chamber so that the water inlet end and the water outlet end can be blocked or connected by the valve body.

Furthermore, the quick switch can be provided for a sanitary device, the valve body further comprising a switching component, which comprises: a closed state, wherein when the switching component is in the closed state, the switching component presses against the blocking element, so that the blocking element abuts the chamber base and blocks the outer chamber and the inner chamber; and an open state, where if the Switching component is in the open state, the switching component releases the blocking element, so that the blocking element can be separated from the chamber base by its own flexibility, whereby the outer chamber is connected to the inner chamber, with the switching element of the valve body being connected to the switching component, and wherein when the switching element is pressed by the pressing part of the tubular body, the switching element causes the switching component to be switched between the closed state and the opened state.

In an advantageous embodiment it can be provided that the switching component has a bistable mechanism.

In an advantageous embodiment it can be provided that the switching component controls a pilot valve of a pressure chamber.

From detailed description of the execution forms

In the following, in connection with the drawings and the preferred exemplary embodiments, the technical measure which serves to solve the predetermined object of the present invention will be explained in more detail.

With reference to Figures 1, 2 and 3, the quick switch for a shower device of the present invention serves to connect a water source A to a water outlet device B, wherein the water source A can in particular be a water pipe, and the water outlet device B can be a sprinkler head or a shower head in shape of a lotus. The quick switch for a shower device comprises a tube body 10 and a valve body 20 .

Referring to FIGS. 3 and 6, the tubular body 10 includes a water inlet end 11 , a water outlet end 12 and a stamping 13 . The water inlet end 11 is for connection to the water source A. The water outlet end 12 is for connection to the water outlet device B . The water outlet end 12 and the water inlet end 11 can come closer to each other or move away from each other. The pressing part 13 is arranged at the water outlet end 12 and moves with the water outlet end 12 . Concretely speaking, in the present embodiment, the pressing member 13 is a cylinder, and one end of the cylinder is connected to a port of the water outlet end 12 through a plurality of connecting rods, while the other end of the cylinder is connected to a Direction of what sereinlassedes 11 runs in a straight line. However, the concrete structure of the pressing member 13 in other embodiments is not limited thereto.

Furthermore, in the present exemplary embodiment, the tubular body 10 further comprises a first tube 14 , a second tube 15 , an elastic component 16 and a stop element 17 .

The water inlet end 11 is formed at one end of the first pipe 14, and the valve body 20 is in the first pipe

14 arranged. An outer wall of the first tube 14 includes a first abutment surface 141 and a step surface 142 . The first abutment surface 141 faces the water outlet end 12 . The step surface 142 faces the water inlet end 11 .

The water outlet 12 is at one end of the second tube

15 trained . The second tube 15 is fitted movably around the first tube 14 so that the water outlet end 12 and the water inlet end 11 can come closer to or away from each other. An inner wall of the second tube 15 includes a second contact surface 151 and an inner ring groove 152 . The second contact surface 151 faces the water inlet end 11 . The inner ring groove 152 is at the other end of the second tube 15 opposite to the water outlet end 12 . Concretely speaking, the second abutment surface 151 is closer to the water outlet end 12 than the inner ring groove 152 .

The elastic component 16 abuts between the first abutment surface 141 and the second abutment surface 151 and tends to allow the water inlet end 11 and the water outlet end 12 to move away from each other. A stable connection between the first tube 14 and the second tube 15 can be produced by the elastic component 16 . The stop element 17 is arranged in the inner ring groove 152 and protrudes from the inner ring groove 152 . The step surface 142 selectively abuts a side surface of the stopper member 17 so that the stopper member 17 can limit a maximum distance between the water inlet end 11 and the water outlet end 12 . In other words, the stop element 17 can be used to ensure that the first pipe 14 cannot be separated from the second pipe 15 when the water inlet end 11 and the water outlet end 12 move away from one another. D. H . that the second tube 15 still abuts the stopper member 17 and the step surface 142 and is stably located in the first tube 14 without being separated even if the elastic component 16 pushes the first tube 14 and the second tube 15 away from each other . To put it concretely, the stop element 17 in the present exemplary embodiment is a ring body. However, it is not limited to this in other exemplary embodiments.

Furthermore , in the present embodiment , female threads 143 are formed on an inner wall surface of water inlet end 11 and male threads 153 are formed on an outer wall surface of water outlet end 12 , whereby connection to water source A and water outlet device B can be simplified . In further exemplary embodiments, there can also be no internal thread 143 and external thread 153; instead, the connection to the water source A and the water outlet device B is made by further structures.

In addition, in the present exemplary embodiment, the pipe body 10 causes the water inlet end 11 and the water outlet end 12 to move closer to or away from one another due to the relative movement of the first pipe 14 and the second pipe 15 to one another. However, it is in other examples are not limited to this. For example, the tubular body 10 can also be a rubber tube in which a middle part of the tubular body 10 deforms radially outwards and protrudes outwards at the same time when it is compressed, so that the two ends can come closer to or away from each other. Alternatively, the tubular body 10 can also be a structure similar to a stretched and bent drinking straw, i. H . that there are a multitude of annular folds on the pipe wall, whereby the two ends can also come closer to each other or move away from each other.

With further reference to FIGS. 4 and 5, the valve body 20 is arranged in the pipe body 10 and can block or connect the water inlet end 11 and the water outlet end 12 . The valve body 20 includes a chamber base 21 , a blocking element 22 , a switching component 23 and a switching element 24 .

The chamber base 21 includes an outer chamber 211 , an inner chamber 212 and a connecting channel 213 . The outer chamber 211 is connected to the water inlet end 11 . The inner chamber 212 is connected to the outer chamber 211 . The connecting channel 213 is connected to the inner chamber 212 and to the water outlet end 12 . The water from the water source A can only flow sequentially through the water inlet end 11 , the outer chamber 211 , the inner chamber 212 and the connection channel 213 to the water outlet end 12 .

The blocking element 22 is flexible and selectively abuts the chamber base 21 and blocks the outer chamber 211 and the inner chamber 212 so that the valve body 20 can block or connect the water inlet end 11 and the water outlet end 12 . The switching component 23 includes a closed state and an open state. When the switching component 23 is in the closed state, the switching component 23 presses against the blocking element 22 so that the blocking element 22 abuts the chamber base 21 and blocks the outer chamber 211 and the inner chamber 212 . When the switching component 23 is in the opened state, the switching component 23 releases the blocking element 22 so that the blocking element 22 can be separated from the chamber base 21 by its own flexibility, whereby the outer chamber 211 is connected to the inner chamber 212 .

The switching element 24 is connected to the switching component 23 . The pressing part 13 of the pipe body 10 can press the switching element 24 of the valve body 20 by the water inlet end 11 and the water outlet end 12 coming closer to each other, and thereby the valve body 20 is switched to block the water inlet end 11 and the water outlet end 12 or to switch the water inlet end 11 and the to connect water outlet end 12 . In other words, the switching element 24 causes the switching component 23 to be switched between the closed state and the open state when the switching element 24 is pressed by the pressing part 13 of the tubular body 10 .

With continued reference to FIGS. 1, 5 and 6 through 9, the present invention, in use, is positioned between the water source A and the water outlet end B. The user only has to push the water outlet device B to let the water inlet end 11 and the water outlet end 12 come closer to each other, so that the switching element 24 of the valve body 20 is pressed by the pressing part 13 and the valve body 20 is thus opened or closed. When the switching component 23 of the valve body 20 is in the open state, as shown in Figures 6 and 7 (Figure 6 and Figure 7 are sectional views from different sides in the same state, the sections of the two figures being vertical), the switching component 23 releases the blocking element 22 so that the blocking element 22 can be separated from the chamber base 21 by its own flexibility, whereby the outer chamber 211 is connected to the inner chamber 212 . Thus, the water can flow through the water inlet end 11, the outer chamber 211, the inner chamber 212 and the connecting channel 213 to the water outlet end 12 in sequence. In this way, the water from the water source A can flow through the present invention to the water outlet end B and be sprayed. When the switching component 23 of the valve body 20 is in the closed state, as shown in Figures 8 and 9 (Figure 8 and Figure 9 are sectional views from different sides in the same state, the sections of the two figures being vertical), the switching component presses 23 against the blocking element 22 so that the blocking element 22 rests against the chamber base 21 and blocks the outer chamber 211 and the inner chamber 212 . Thus the water can only flow to the outer chamber 211 via the water inlet end 11, i. H . that the water is blocked by the blocking element 22 and thus the water outlet device B no longer sprays the water.

The advantage of the present invention is that the valve body 20 is arranged in the pipe body 10 and can block or connect the water inlet end 11 and the water outlet end 12 of the pipe body 10; that the water inlet end 11 and the water outlet end 12 of the pipe body 10 can come closer to each other or move away from each other; and that the pressing part 13 is formed at the water outlet end 12 so that when When the water inlet end 11 and the water outlet end 12 come closer to each other, the pressing part 13 can thereby press the switching element 24 of the valve body 20 and thus the water inlet end 11 and the water outlet end 12 of the pipe body 10 are blocked or connected by the valve body 20 . Thus, the quick switch for a shower device of the present invention is connected between the water source A (e.g. a water pipe) and the water outlet device B (e.g. the sprinkler head), whereby the user can slide the water outlet device B directly that the water inlet end 11 and the water outlet end 12 of the tubular body 10 approach each other. This blocks or connects the water inlet end 11 and the water outlet end 12 of the pipe body 10 and in turn controls whether the water flows from the water source A to the water outlet device B through the present invention. In other words, the user can control whether the shower device sprays the water or not by directly sliding the water outlet device B, so that he can realize quick switching even with his eyes closed, without otherwise looking for the switch arranged on the wall in the dark searching and even accidentally touching the hot and cold water controls.

Fig. 10 and 11 show different representations of a use according to the invention of a quick switch 25 according to the invention on a sanitary device 26 , here in the form of a washbasin with a washbasin fitting 44 .

The quick switch 25 is screwed into a wall fitting 42 instead of an angle valve. A water line 41 is connected to the quick switch 25 and leads to the sink faucet 44 . The high-speed switch 25 can be opened and closed by external pressure on the water line 41 .

Fig. 12 shows a detailed representation of the quick switch 25 according to the invention from Figs. 10 and 11.

The quick switch 25 connects a water inlet end 11 to a water outlet end 12.

Fig. 13 shows a detailed view of the exploded view of the quick switch 25.

Components and functional units that are functionally and/or constructively similar or identical to the preceding exemplary embodiments are denoted by the same reference symbols and are not described separately again.

FIG. 14 shows an exploded view of the valve body designated as a whole with 20 in FIG.

Figures 15-20 serve to explain how the high-speed switch 25 works.

Components and functional units that are functionally and/or constructively similar or identical are denoted by the same reference symbols and are not described separately again.

The explanations for FIGS. 1-9 therefore apply accordingly to FIGS. 10-20.

Fig. 15 shows an axial section through quick switch 25.

The switching position in which the valve body 20 is open is shown.

In this switching position, water can run from the water inlet end 11 via the outlet 40 to the water outlet end 12 .

FIG. 16 shows an axial section which, compared to FIG. 15, is rotated by 90° about a longitudinal axis of the high-speed switch 25. The exemplary embodiment according to FIGS. 10-20 differs from the preceding quick switch 25 by a compensating volume 28, which is described in more detail below.

In FIG. 16, the compensating volume 28, which is limited in each case by a piston 30, is minimal.

If the first pipe 14 is now moved towards the second pipe 15 (cf. FIG. 17), water is displaced on the outflow side of the valve body 20 .

If the water outlet end 12 is not pressure-free, the water is displaced into the compensating volumes 28 . Here, the pistons 30 are moved against the restoring force of the restoring elements 29 . The restoring elements 29 are arranged at atmospheric pressure.

The rear side 31 of the piston 30 can be relieved of pressure via ventilation openings 32, since the ventilation openings 32 open into the ambient air or atmosphere.

This actuation movement causes the bistable mechanism 35 to switch over. To be more precise, the counter-switching element 46 rotates here by 45° around the longitudinal axis of the high-speed switch 25. As a result, the pilot valve 37 is closed, so that a pressure can build up in the inner chamber 212. This pressure build-up moves the inner chamber wall 38 (see FIG. 18) so that the blocking element 22 is pressed against the valve seat 39 .

The valve body 20 is thus closed and no water can flow from the water inlet end 11 to the water outlet end 12 .

If the first tube 14 is now moved against the second tube 15 again, the counter-switching element 46 of the bistable mechanism 35 rotates again by 45° (cf. FIG. 19). This leads to an opening of the pilot valve 37 so that the inner chamber 212 empties.

This means that the inner chamber wall 38 is moved by the operating pressure on the side of the water inlet end 11, so that the inner chamber 212 is reduced.

The situation according to FIG. 20 in which the valve body 20 is open to allow water to flow from the water inlet end 11 to the water outlet end 12 .

the fig . 21-23 and 24-25 show two exemplary embodiments of a sanitary device 20 in the form of a shower device 27 with a quick switch 25 according to the invention.

Since the shower head 45 represents a flow obstacle in each case, the water line 41 and thus the water outlet end 12 are not pressure-free, but there is a certain operating pressure when the fitting 43 is open.

This requires that the high-speed switch 25 has a compensating volume 28 of the type described.

The preceding description relates only to the preferred exemplary embodiments and is not intended to limit the present invention in any way. However, although the present invention has already been disclosed with the preferred embodiments as disclosed above, they are not intended to limit the present invention. Anyone skilled in the art who has ordinary knowledge in the field of technology should be able to make some changes or modifications as equivalent embodiments of the equivalent changes with the aid of the technical contents disclosed above without departing from the technical solution of the present one to deviate from the invention. All simple variations, equivalent changes and made based on the technical essence of the present invention Modifications for the above embodiments without

Deviations from the content of the technical solution of the present invention should be construed as being covered by the scope of the technical solution of the present invention.
