Description

The present invention relates to a water pipe having a housing in which a receptacle (container) filled with a liquid medium and provided with at least one suction connection and a heating chamber connected to the receptacle via a suction hose are integrated. The heating chamber has a holding fixture for the capsule that serves to contain the smoke medium.

Also known as shishas or hookahs, the water pipes originally originated in the Middle East. In recent years, they have become increasingly popular as an alternative to cigarettes, especially among teenagers and young adults. Such water pipes are known, among other things, from US Pat. No. 4,31906 or US Patent Application Publication No. 2012/0042884. Such a water pipe has a receptacle that can be partially filled with water or other liquid medium. When the mouthpiece is sucked, a negative pressure is generated in this receptacle. In addition, the smoke column partially protrudes into the water, which has a headpiece at its upper end to receive the cigarette, which is heated by the charcoal above the cigarette. The mixture of air, vapor and smoke particles produced when the cigarette is heated is then inhaled by the smoker. It is clear that heating with red-hot charcoal can cause carbon monoxide poisoning, combustion accidents, or even fires in extreme cases. Such traditional water pipes are known, among other things, from US Patent Application Publication No. 2014 / 0,069,446 or US Patent Application Publication No. 2012 / 0,042,884. Since water pipes are manually filled, legally compliant filling of water pipes is often not guaranteed. Therefore, as a general rule, water pipes known today should be operated with a guarantee of fresh air supply only outdoors or in the room.

Water pipes using this technology are also relatively heavy and have a large volume, so they have to be assembled from several parts, and it is difficult to transport them as individual parts. Cleaning is also time consuming and often does not meet hygiene standards. For example, electronic water pipes are known in US Pat. No. 4,133,318, but they do not satisfactorily alleviate some of the above problems. The water pipes known from International Publication No. 2017/08545 have also proved to be particularly advantageous. However, there is still a technical deficiency in the area of the connection between the water tank and the housing of the water pipe because air escapes. This transition from the receptacle represents a type of predetermined break point with corresponding obstacles to handling and smoking experience.

Thus, the present invention has the task of creating a water pipe characterized by a high level of airtightness and thus effectiveness for a smoking experience.

This problem is solved by providing a valve in a region where the receptacle and the housing portion accommodating the electronic unit are detachably connected and the mouth of the suction hose opens into the receptacle.

The housing of the water pipe essentially comprises a receptacle as a first housing portion, a second housing portion accommodating an electronic device and a suction hose, and a third housing portion accommodating a heating chamber for capsules, preferably. Are listed in order from top to bottom. According to the present invention, the receptacle and the housing portion accommodating the electronic unit are detachably connected to each other and further connected by a valve that guarantees an improved seal. This valve is a particularly effective way to prevent secondary air from escaping through the water pipe.

Preferably, the valve is centrally located for this purpose and, if necessary, a portion of the valve projects into the receptacle.

It has already been mentioned that the receptacle is located above the housing that houses the electronic unit. In this sense, it suggests that the valve should fit exactly into the suction hose protruding upwards from the housing. The lower end of the suction hose opens into the heating chamber, and the suction hose that passes through the housing that houses the electronic unit is connected so that the upper end fits the valve precisely, so secondary air does not escape in this entire area. ..

Specifically, it means that the suction hose is open from below to the base of the receptacle, which must be a whole solid enough to form a stable attachment to the valve and the end of the hose. It doesn't become.

The preferred design of the invention is that the base of the receptacle has a hollow space with an integrated central mounting plate for fixing the suction hose. A mounting plate centrally located in the hollow space of the otherwise relatively rigid base serves as a mounting for the suction hose.

In addition, the suction hose is designed to open into the mounting plate. Therefore, the suction hose is terminated within the receptacle, preferably at its base, and in a particularly advantageous manner, within the mounting plate integrated with the receptacle base.

It goes without saying that the suction hose and valve are located on the longitudinal axis of the water pipe. Therefore, for example, when assembling the receptacle and housing after cleaning, the suction hose will directly find the position in the valve.

Installation between this type of suction hose and valve may be advantageous if a seal is provided at the base of the receptacle and at the mouth of the suction hose. They provide a seal between the suction hose and the receptacle base and / or mounting plate located in the hollow space, thereby providing a reliable and safe air path through the suction hose and its connections. Secure without loss.

It has already been mentioned that the receptacle and the housing portion accommodating the electronics are detachably connected to each other. The preferred design of the invention provides that the housing portions containing the receptacles and electronics are connected to each other at the edges, which is then complemented by an accurate fit between the top of the suction hose and the valve. ..

For example, it has been considered that the receptacle and the housing portion including the electronic device are connected to each other via an all-around screw, a snap-in connection, a plug-in lock, or an all-around plug-in connection. Preferred designs are thread connections and threads. The receptacle is screwed into a housing that houses the electronic unit, which includes establishing a connection between the suction hose and the valve. Receptacles, housings, suction hoses and valves are synchronized in an unavoidable way with a secure external connection and secure valve positioning.

The receptacle is closed with a lid at the end facing away from the suction hose. It is desirable that the receptacle has an inwardly projecting collar at its upper end and a sealing component integrated facing the collar on its lower lid.

An O-ring is preferred so that the seal is already in place the moment the lid is connected to the receptacle. Again, the preferred design is screw connection.

The fact that the housing that houses the electronics has switches, indicator lights, connections, etc. above it makes these switches, indicator lights, and connections easily accessible only after the receptacle has been disassembled. Otherwise, it is advantageous in that it does not get in the way and does not spoil the design.

The purpose is to ensure a high degree of efficiency in heat transfer between the heating chamber and the capsule inserted into the heating chamber, which is with one holding fixture or parts of this holding fixture and the other capsule. It is made possible by the precise fitting between. The cone is essential for this precise fit. This allows for a particularly targeted heat transfer by the precise fit between the sidewall of the retaining fixture surrounding the capsule and the capsule itself. The tighter the capsule is placed within the retainer, the more effectively the heat from the outside, i.e. from the direction of the heating chamber, is transferred towards the capsule. A particularly advantageous variant for such an accurate fit is that the sidewalls of the retaining fixture taper in a conical shape towards the inside of the heating chamber, with the conical being about 5 ° to 10 °, preferably about. It has an angle of 7 °. The ideal geometry is that the diameter of the retaining fixture or the retaining fixture between the front and back of the capsule is constantly increasing by about 1.1 to 1.25 times, preferably about 1.17 times. Sometimes achieved. According to one design of the invention, the retaining fixture has a closure ring on the outside that extends laterally with respect to the longitudinal axis of the housing, in which the retaining fixture for the capsule is integrated. That is, the closure ring or heating chamber is arranged and designed to correspond to each other so that the closure ring has a central opening in which the capsule is placed within the holding fixture. Depending on the arrangement of the receptacle, heating chamber, etc., the closure ring also forms the top or bottom of the housing or heating chamber. In addition, the closure ring also acts as a stopper for the collar on the capsule when the capsule is inserted into the heating chamber. Therefore, the closure ring ensures that the capsule is placed in the heating chamber, among other things, for the following reasons:

The capsule has a collar that hits the closure ring.

The used capsule comes into contact with the part of the water pipe where the user may be exposed to high temperatures, thanks to the mechanism that pushes the used capsule out of its position in the holding fixture in the direction opposite to the insertion direction. It can be extruded from those positions within the retaining fixture in the heating chamber without. Such health hazards due to high temperatures up to 200 ° C. can be envisioned for heated water pipe capsules and are therefore excluded as well as capsule clogging when pulled out. Any capsule expansion process is also irrelevant, as the capsule can be extruded from the retaining fixture from the direction of the receptacle in a particularly effective manner. The fact that the mechanism can be operated from outside the heating chamber has the same purpose, in particular, to create a sufficient distance between the operator's hand and the capsule inside or inside the heating chamber.

The advantageous design of the present invention provides that the suction hose is attached so that it can move in the direction of its longitudinal axis. This is a particularly optimal solution for such a mechanism, as the existing suction hose has the additional function of acting as a mechanism for removing the capsule. This is done from a completely safe distance with respect to the high temperature of the used capsules in the heating chamber. By simply pushing on the suction hose, a force is applied to the capsule in the direction opposite to the direction in which the capsule was inserted. As a result, the capsule is necessarily released from its position within the retaining fixture in the heating chamber. For ease of handling, it is considered that the suction hose is attached so that it can move against the force of the spring, so that the suction hose returns to the starting position and releases the capsule after use. However, the play of the suction hose during operation is restricted.

The present invention is particularly characterized in that the water pipe ensures an optimal total air supply to the air exiting the capsule through the mouthpiece. This is due to the special connection between the water tank and the housing of the water pipe, specifically the central housing that houses the electronics. When the receptacle and the central housing section are assembled together or screwed together, a particularly secure connection is established by a valve located in the center of them, so that the heating chamber and the central housing section that houses the electronics And the reliable transport of air to and from the water tank via the suction hose ensures that the air cannot escape from it. In addition, the suction hose is equipped with a central mounting plate that opens into the receptacle, specifically its hollow base, and serves as a mounting portion for the suction hose in this area of the water pipe.
