Description

The invention relates to a bottle attachment. Together with a bottle it forms a portable bidet.

Bidets are used to clean the anal and intimate areas with water. In the case of stationary bidets, a hand shower is used to regulate the water supply. Also known are stationary bidets, which can be designed as part of a toilet seat. The water supply is controlled by a manual valve, which can be equipped with a hand wheel, for example. If the hand wheel is turned on, the water pressure pushes a nozzle of the bidet into an extended end position, in which the water reaches the desired part of the anal or genital area. If the hand wheel is turned, the nozzle moves back to the starting position under spring pressure. Such stationary bidets have proven themselves.

The bidets described above are dependent on a domestic water supply and are therefore regularly designed as a stationary unit. However, it has been found that where a stationary bidet is not available, although there is a need for the hygienic comfort of a bidet. This applies, for example, to trips where no bidet is available, or to countries where a domestic water supply network is available but the institution of a bidet is not widespread.

Portable bidets have recently entered the market to complement stationary bidets. A commercially available plastic bottle is used as a water reservoir. The empty bottle is filled with water. A bottle attachment, which has a nozzle, is then placed on the bottle. When the bottle is pressed, water comes out of the nozzle. The water pressure and the jet duration of the water can be controlled by the pressing pressure and the pressing duration.

The well-known portable bidet is a useful addition to the stationary bidet. It is small and can therefore be taken with you on trips without taking up much space. In addition, plastic bottles are so common around the world that there is no need to take a bottle with you. If you don't want to take it with you (e.g. for reasons of space), a plastic bottle can be bought on site and used as a water reservoir for the portable bidet after the contents have been consumed.

Even if the basic concept of the portable bidet has proven itself, it has been found that handling can be improved. In particular, with known bidets it can happen that in the rinsing position, in which the bottle head is directed downwards, water emerges from the portable bidet even before the actual rinsing process. This is where the invention comes in.

The invention is based on the object of further developing a portable bidet to the effect that water does not emerge unintentionally before the actual rinsing process.

This object is achieved according to the invention by a bottle attachment with a fastening section that has a water inlet and with a nozzle section that has a water outlet, the water inlet and the water outlet being connected by a flow channel, and a safety valve being arranged in the flow channel, which opens towards the water outlet.

The bottle attachment according to the invention can be inserted into a bottle. In particular, it can be inserted into the neck of a conventional plastic bottle. For this purpose, the bottle attachment has a fastening section. At least one sealing ring is preferably arranged on the fastening section, which seals the bottle attachment against the plastic bottle. In addition to sealing, the at least one sealing ring ensures that the bottle attachment is held securely in the plastic bottle. The bottle attachment can also have several sealing rings, each with different diameters. This means that the bottle attachment can be used with different bottle neck diameters.

A water inlet is formed in the fastening section, through which the liquid enters the bottle attachment from the bottle. The liquid exits the nozzle section of the bottle attachment. The water inlet and the water outlet are connected by a flow channel. So is the bottle attachment in a bottle plugged in and pressure is applied to the bottle, the liquid flows into the water inlet, through the flow channel and then out of the water outlet. The water outlet is preferably designed as a nozzle that shapes and focuses the water jet.

According to the invention, the bottle attachment has a safety valve which is arranged in the flow channel and opens in the direction of the water outlet. The invention is based on the finding that the water column of the bottle in the prior art is sufficient to allow water to escape from the bidet. So if the known bidet is brought into its flushing position, water occurs due to the water pressure of the water column in the bottle. The safety valve according to the invention, on the other hand, ensures that water only emerges from the water outlet when the user presses on the bottle. The safety valve therefore only opens at a certain pressure. This prevents liquid from escaping from the portable bidet in an uncontrolled manner.

Insofar as liquid is mentioned within the scope of the invention, water is primarily considered. However, it is also conceivable that water mixtures, for example with soap or other additives, can be used.

The safety valve is preferably set in such a way that it only opens at a pressure which is greater than the pressure exerted on the safety valve by the maximum liquid column in the plastic bottle (without pressurizing the bottle). A maximum liquid column is when the bottle is completely full.

In a further development of the invention it is proposed that the safety valve has a closing body which is prestressed in the direction of the water inlet. In the context of the invention, this means the flow direction. The structure of such a safety valve corresponds to that of a non-return valve, the function of the non-return valve being modified to the extent that the non-return valve does not have to ensure that any back-flowing liquid is held back. Rather, the prestressing of the closing body serves to hold back the liquid that is present until a certain pressure overcomes the prestressing due to the bottle being compressed. According to the invention, the safety valve then opens in the direction of the water outlet.

Advantageously, the safety valve is designed as an insert that is inserted into the bottle attachment. Such a construction is particularly easy to assemble. The bottle attachment advantageously forms a receptacle for the insert. The insertion depth of the insert is preferably limited by a shoulder. The shoulder advantageously tapers the cross section of the receptacle and expediently forms a stop.

The insert is preferably arranged in the fastening section. This leads to a particularly compact construction of the bottle attachment.

In addition to easy handling of the portable bidet and a compact design, its safe use also plays a role. This includes, among other things, a reliable seal to prevent water from escaping from the portable bidet. In this context, proposed that the nozzle portion has a handle in which the water outlet is located. The handle allows the bottle attachment of the present invention to be securely inserted into the bottle. The insertion must take place under a certain pressure so that the sealing rings come to rest on the inside of the bottle neck.

The handle has another advantage. Because it is arranged on the nozzle section, alignment of the water outlet is advantageously possible. As a result, orientation is facilitated even in the case of round bottles, which, because of their round cross-sectional shape, are difficult to align. This is particularly true when the handle has a profiled shape, which is considered particularly advantageous. The profile can be designed in many ways. Within the scope of the invention, a profiled shape is understood to mean a cross-sectional shape that is not round. For example, the profile can be elongate. Then it is easy to grasp from both (long) sides and at the same time specifies the direction of the water outlet.

Preferably, the handle is elongate and has first and second ends, with the water outlet being located at the second end. It is particularly advantageous if the water outlet is elongate, preferably extending in the direction of the longitudinal axis of the fastening section. As a result, a water jet is formed which is not round but elongated, as a result of which the water jet can advantageously wet the part of the human body.

An advantageous embodiment of the invention is characterized in that the handle consists of a base plate extended. As a result, the hand can be supported when the bottle attachment is pressed into the bottle, which means that the bottle attachment can be handled better. If the base plate is round, as is considered advantageous, it suitably covers the bottle neck, which is also round, and reduces the risk of injury when handling the bottle attachment.

in a schematic representation, a second sectional view of the bottle attachment, from which the structure of the safety valve can be seen.

The following will refer to the figures 1 and 2 referenced. The bottle attachment according to the invention has a fastening section 1 and a nozzle section 2 . In the attachment portion 1 is a water inlet 3 ( figure 2 ) educated. A water outlet 4 is formed in the nozzle section 2 . The water outlet forms a nozzle. It is advantageously elongate and preferably extends in the direction of the longitudinal axis L of the fastening section 1.

Four sealing rings 5, 6 are arranged on the fastening section. The sealing rings 5 have a smaller diameter than the sealing rings 6. As a result, the bottle attachment according to the invention is able to be used in bottles with different bottleneck diameters. The sealing rings 5, 6 seal the bottle attachment against a bottle 7, as shown in figure 1 is only indicated by dashed lines. On the other hand, the flexibility of the sealing rings 5, 6 ensures that the bottle attachment is held firmly in the bottle 7 and does not come loose from the bottle 7 even when the pressure is higher.

If necessary, the bottle attachment according to the invention is used as in figure 1 shown inserted into a conventional bottle 7, which has previously been filled with a liquid, in particular water. The bottle with the bottle attachment is then moved downwards and aligned in such a way that the water jet emerging from the water outlet 4 reaches those parts of the human body which are to be cleaned. As soon as the user squeezes the bottle 7, water comes out of the water outlet 4. Plastic bottles are particularly suitable for use with the bottle attachment according to the invention, which give way when the side walls are pressed in order to spray the water out of the water outlet 4 .

For attaching the bottle attachment to the bottle 7, the bottle attachment has a handle 8 which extends out of a round base plate 9. As a result, the bottle attachment can be easily inserted into the bottle 7 and, if necessary, aligned by means of a rotary movement. The handle 8 is particularly easy to grip when it is elongated is trained. The oblong shape also makes it easier to align the water outlet 4 so that the user knows in which direction the water jet is going. For reasons of space, it is particularly advantageous if the water outlet 4 is arranged in the handle 8 . In particular, it can be provided that the handle 8 has a first end 10 and a second end 11, with the water outlet 4 being arranged in the second end.

With reference to figure 2 it becomes clear that the water inlet 3 and the water outlet 4 are connected by a flow channel 12 . The flow channel extends in the direction of the longitudinal axis L of the fastening section 1 and advantageously runs in the nozzle section 2 perpendicular to its direction of extension in the fastening section 1.

The safety valve 13 according to the invention is arranged in the flow channel 12 . The water from the bottle 7 thus passes through the safety valve 13 before it emerges from the water outlet 4. The safety valve 13 is preferably accommodated in a receptacle 14 which is formed in the fastening section 1 . The recording is limited by a shoulder 15, which limits the insertion depth of the safety valve 13.

The safety valve 13 is preferably designed as an insert and has at least one sealing ring 16 on its outer wall, which rests against the inner wall of the receptacle 14 . The sealing ring 16 holds the insert in the bottle cap and at the same time seals the insert against the fastening section 1.

figure 3 shows the bottle attachment in a further sectional view, from which the structure of the safety valve 13 can be seen. The safety valve 13 is (opposite figure 2 ) shown in a sectional view. It has a closing body 17 which is guided in a bearing 18 so as to be longitudinally displaceable. In the unloaded state, the closing body 17 seals against a sealing seat 19 and is prestressed against the sealing seat 19 by means of a spring 20 . Such safety valves actually serve to prevent the backflow of a liquid. According to the invention, however, the bias of the spring 20 ensures that no water from the bottle 7 ( figure 1 ) emerges when the bottle 7 is placed in its injection position, as previously described, in which the bottle cap is below the bottle. Despite the water pressure due to the water column, advantageously no water runs out of the bottle 7 due to the prestressing of the closing body in the direction of the water inlet 3 . Only when pressure is exerted on the bottle 7 does the water force overcome the prestressing of the closing body and the water can pass through the closing body 17 in the direction of the arrow P and emerge from the water outlet 4 .
