Description

TECHNICAL FIELD

[0001] The present disclosure relates to a water guiding part, and a watering device to which the water guiding part is mounted with an integrated protection against damages caused by freezing conditions.BACKGROUND

[0002] Gardening and yard maintenance, like so many other pursuits, are made easier and more enjoyable when the right tools are available to the gardener for each job. Every garden or yard needs suitable and effective liquid application, particularly water application. When mother nature is not cooperative, or for covered areas, a watering device is necessary to provide adequate liquid supply.

[0003] The watering device includes devices such as spray guns, spray nozzles, spray lances, and the like. These devices are often used to apply liquid from a tap to a garden, plant or other target using the hose, and the like. The watering device are reconfigurable or relatively easily configured for use with hoses using quick connect assemblies. However, even with an improved ability to couple the watering device easily fluidically with the hose, gardeners often prefer to leave the watering device and the hose in fluidly coupled state. Thus, for example, gardeners leave a particular spray nozzle attached to a particular hose that is further attached to a particular tap. This particular setup is frequently used (or at least most frequently used) or otherwise convenient for the gardener.

[0004] When gardeners become used to leaving the watering device and the hose in the fluidly coupled state, they forget to pay attention to certain situations that may arise and damage the watering device and / or the hose. For example, if the temperature dips and a freeze ensues, residual liquid left in the watering device and / or the hose may expand with the freezing and damage the watering device and / or the hose. In particular, again as an example, if the spray nozzle dangles from a hose reel, the liquid may rest in the spray nozzle (e.g., near the lowest point) and expand due to freezing. If the liquid volume happens to be sufficient to initially fill a void space in the spray nozzle, the expansion due to freezing damages the components forming or connected to the void space in question and the spray nozzle is effectively ruined. While the problem is avoidable with extra effort and attention from the gardener, it is desirable to provide the gardener with a technical solution instead.

[0005] An example of a watering device is provided by German Patent DE 10 2005 035 037 B4 (hereinafter referred to as the '037 reference). The '037 reference discloses a water dispensing device for garden watering with a compensation body in the cavity to counteract pressure increase during freezing. By utilizing elastic materials and gas volumes, the device expands the cavity volume, preventing damage from frozen water.SUMMARY OF THE INVENTION

[0006] In view of the above, it is an objective of the present invention to solve or at least reduce the drawbacks discussed above. The objective is at least partially achieved by a water guiding part for a watering device and a watering device comprising such a water guiding part.

[0007] According to an aspect of the present invention, the water guiding part for a watering device is disclosed, wherein the watering device comprises an inlet configured to guide a liquid into the watering device, and an outlet configured to guide the liquid out of the watering device, wherein the water guiding part is configured to form at least part of a connection between the inlet and the outlet. The water guiding part according to the aspect of the present invention comprises a first section and a second section, wherein the first section and the second section are formed from the same material. The water guiding part is characterized in that the second section is configured to provide stability to the water guiding part, and the first section is configured to change its shape to compensate frost occurring in the water guiding part.

[0008] The present disclosure provides an improved watering device that advantageously comprises the water guiding part having the frost compensation function in its own, without necessarily requiring any external frost compensator component to be coupled to respectively into it. The water guiding part has the first section and the second section that are formed from the same material. Thereby the manufacturing of the water guiding part is easy. The first section and the second section provide the frost compensation function and the stability respectively rigidity for a longer working life of the water guiding part and / or the watering device. The first section advantageously protect the water guiding part and thereby the watering device, from damage due to frost formation inside the water guiding part. Further, the first section is designed geometrically and / or structurally different from the second section and at the same time from the same material as the second section. Thereby, the first section allows to compensate for potential expansion of liquid left in the water guiding part when freezing conditions are encountered. Further, the first section of the water guiding part is capable of enduring repeated cycles of compression and expansion.

[0009] For example, if the liquid is frozen and thereby expands its volume inside the water guiding part, the first section of the water guiding part expands (i.e., undergoes volumetric expansion). Afterwards, if the frozen liquid is thawed again to its liquid state, the first section of the water guiding part contracts (i.e., undergoes volumetric contraction) again. Hence, the first section expands and contracts to compensate for the volumetric expansion respectively compression of the liquid. Thereby, possible damage to the water guiding part and the watering device may be avoided.

[0010] According to an exemplary embodiment of the invention, the water guiding part may be an elongated body with a linear or a non-linear shape. Further, the water guiding part is configured to form at least part of the connection between the inlet and the outlet such that a liquid flow therethrough may be allowed. Further, the liquid may be any liquid for use with the water guiding part. However, preferably, the liquid may be water, as water is a widely used liquid for irrigation or cleaning purposes.

[0011] According to an exemplary embodiment of the invention, the first section is configured to be reversibly expandable to compensate frost occurring in the water guiding part.

[0012] The first section may be configured to undergo a volumetric expansion when the liquid in the water guiding part freezes, and to undergo a volumetric contraction when the liquid in the water guiding part melts / thaws again. Hence, the first section may regain its original shape and size, or in other words, it may get back to its original state.

[0013] According to an exemplary embodiment of the invention, the watering device may entirely constitute the water guiding part. In other words, the water guiding part may span across an inner volume of the watering device from the inlet to the outlet such that the water guiding part may constitute the entire fluid channel within the watering device. Further, the water guiding part may engage respectively be attached with the housing respectively the body of the watering device or may serve as an inner layer of the housing respectively the body of the watering device. Thereby the water guiding device may structurally strengthen the watering device.

[0014] According to an exemplary embodiment of the invention, the first section and the second section are integrally formed from the same material. The first section and the second section may be integrally formed using any related manufacturing method. Further, this may ensure frost compensation without any additional parts, and without using different materials.

[0015] According to an exemplary embodiment of the invention, the material is an amorphous material, in particular an amorphous plastic, more in particular acrylonitrile butadiene styrene (ABS), or a semi-crystalline material, in particular a semi-crystalline plastic, more in particular polypropylene (PP). The amorphous material respectively the amorphous plastic, particularly the ABS, may provide necessary and repeated volume change, namely expansion followed by compression to prevent the water guiding part and thereby the watering device, from damage due to frost. Using ABS may provide the possibility that the first section reliably regains its original shape after expansion(s) and compression(s). Additionally, the ABS may provide sufficient stability to the second section. Alternatively, a semi-crystalline material respectively plastic, such as polypropylene (PP), may be used for forming the first section and the second section. The semi-crystalline material respectively plastic may provide a sufficient ability for repeated volume change of the first section and an enhanced stability of the second section. Alternatively, another plastic, e.g., polyoxymethylene (POM) may be used. Further, the used plastic may be chosen according to the requirements as long as the material of the first section has enough elasticity to withstand the required number of expansion and compression cycles.

[0016] According to an exemplary embodiment of the invention, the first section comprises a first wall thickness, and the second section comprises a second wall thickness, wherein the first wall thickness is thinner than the second wall thickness. The second wall thickness is greater than first wall thickness to form a robust structure for the water guiding part such that the water guiding part may have structural stability, e.g., to withstand a pressure present inside the water guiding part.

[0017] According to an exemplary embodiment of the invention, the first section comprises a first wall thickness, wherein the first wall thickness is configured such that the first section is reversibly expandable to compensate frost occurring in the water guiding part. The first wall thickness may be configured to provide required strength and elasticity to the first section of the water guiding part. Thereby, the first section may be able to experience volume expansion without any wear or damage and may be able to reliably regain its original state as the frost starts to liquidate again.

[0018] According to an exemplary embodiment of the invention, the first section is configured to change its shape due to a temperature change by at least 10% of an inner volume surrounded by the first section. The first section may expand its shape such that an inner volume surrounded by the first section expands by at least 10% to compensate for an increase in volume of the liquid in the water guiding part due to decrease in temperature inside the water guiding part. Thereby, the water guiding part may be prevented from any damage due to increase in volume of the liquid inside the water guiding part. 10% of increase of the inner volume surrounded by the first section may provide a compromise between a temperature drop which may be withstand by the watering device and material costs for producing the watering device.

[0019] The change of the inner volume surrounded by the first section may be measured based on an original volume surrounded by the first section compared to the volume surrounded by the first section after an expansion and therefore a change of shape of the first section. The inner volume surrounded by the first section according to the present invention may be seen as a volume radially surrounded by the first section. Radially surrounded may be seen relative to a direction of flow of the fluid through the first section. Additionally, a length of the first section used for calculating the volume surrounded by the first section may be measured from a downstream end of the first section to an upstream end of the first section. In other words, the length of the first section may be measured from a transition of the second section to the first section and a transition from the first section to the further second section.

[0020] According to an exemplary embodiment of the invention, the first section is configured to change its shape due to a temperature change by at least 25% of an inner volume surrounded by the first section. The first section may expand its shape such that an inner volume surrounded by the first section expands at least 25% to compensate for an increase in volume of the liquid in the water guiding part due to decrease in temperature inside the water guiding part. Thereby, the water guiding part may be prevented from any damage due to increase in volume of the liquid inside the water guiding part. 25% increase of the inner volume surrounded by the first section may provide an increased temperature range in which the watering device may be usable.

[0021] According to an exemplary embodiment of the invention, the first section comprises a softer structure than the second section. Thereby, the first section may conveniently change its shape and thereby the inner volume surrounded by the first section, and at the same time, the second section may provide the needed stability. Hence, the watering device may at the same time withstand temperature changes, particularly temperature drops, and at the same time the watering device may have an increased service life.

[0022] A softer structure according to the present invention may denote that even though the first section and the second section are formed from the same material, the material is formed such that the first section has a structure which is elastically deformable due to a formation of ice, while the second section has a structure which is more rigid compared to the first section's structure and which is stabilizing the watering device during formation of ice.

[0023] According to an exemplary embodiment of the invention, a further second section comprises a further second wall thickness being thicker than the first wall thickness, wherein the further second wall thickness is configured to provide stability to the water guiding part, and wherein the first section is positioned in-between the second section and the further second section. Particularly, the further second section is made from the same material as the second section and the first section. Particularly, the further second section is integrally formed with the first section and the second section. Hence, the water guiding part may be easily manufactured. The further second section may be a mirror image of the second section. Thereby, a substantially constant stability may be provided to the first section and therefore to the water guiding part.

[0024] According to an exemplary embodiment of the invention, the further second wall thickness and / or the second wall thickness is at least 1.10 times, in particular 1.5 times, more in particular 2 times, thicker than the first wall thickness. The further second wall thickness and / or the second wall thickness is at least 10 percent, in particular at least 50%, more in particular at least 100%, additionally thicker than the first wall thickness for compactness and at the same time structural rigidity of the water guiding part. Particularly, the further second wall thickness and the second wall thickness have equal thickness or different thickness. If the further second wall thickness and the second wall thickness are equal, a uniform stability is providable to the first section. If the further second wall thickness and the second wall thickness are different from each other, one part of the first section which is closed to the thicker section may have a greater stability. Hence, the stability of the water guiding part may be easily adapted to the requirements. According to a further aspect of the present invention, a watering device comprises the water guiding part according to the present invention, the inlet configured to guide a liquid into the water guiding part, and the outlet configured to guide the liquid out of the water guiding part, wherein the water guiding part forms at least part of a connection between the inlet and the outlet. The watering device may further comprise, i.a., a valve, a pressure reducer, a trigger, a housing, and other components for watering operations. The watering device according to the present invention may be used during a wide temperature range, because of the water guide part's ability to compensate the volume change caused by frozen water within the water guiding part.

[0025] According to an exemplary embodiment of the invention, the watering device is a water application device for a garden, in particular a sprayer, a water computer, or a sprinkler. The watering device may be a multi sprayer, a balcony sprayer, a soft sprayer, a cleaning nozzle. The watering device may be a modular water application device with one housing comprising a handle and / or an actuating portion being configured to be removably couplable with different spray heads or nozzles. The water application device for the garden according to the present invention may be left outside even if low temperature and therefore frost occur, without the user needs to fear that the water application device may get damaged. Particularly, the water application device may be manufactured at low costs. Hence, the water application device may be reliable with long service life and may be available at a good price. Additionally, when the water application device is formed in a modular way, only one housing may be used with different heads and may be maintainable in an easy way.

[0026] According to an exemplary embodiment of the invention, the water guiding part is removably mounted in the watering device. The watering device may have two similar or mirror image housing halves coupled to each other using fasteners such as screws. The water guiding part may be comfortably and reliably held between the two housing halves of the watering device when the two housing halves are fastened to each other.

[0027] Before discussing the invention with the help of the drawings the invention will be briefly discussed in general. A water guiding part is provided for a watering device, wherein the water guiding part is provided with thin-soft first section together with a stability second section and a further stability second section to ensure necessary strength respectively rigidity and at the same time frost compensation ability.

[0028] The water guiding part according to the present invention may have no additional parts for frost compensation and may not require any additional assembly or manufacturing costs. Hence, the water guiding part and therefore the watering device may be reliable, have an increased service life and at the same time may be affordable.

[0029] According to an exemplary embodiment of the invention, the water guiding part may have the first section having a first wall thickness, the second section having a second wall thickness, and the further second section having a further second wall thickness, wherein the further second wall thickness and the second wall thickness are both thicker than the first wall thickness. Hence, the second section and the further second section provide rigidity and at the same time the first section provides frost compensation ability to the water guiding part. Therefore, a reliable watering device may be provided.

Further, the inlet 122 is at least partially disposed outside of the housing 102 and is formed as a nipple.

[0039] FIG. 2 illustrates a perspective view of the housing 102 of the watering device 100 with the housing half 104 removed. The housing halves 104 and 106 are generally symmetrical mirrored structures. In other words, the housing halves 104 and 106 have a substantially similar structural design or structural features. The housing half 106 comprises a plurality of screw bosses 124. Likewise, the housing half 104 comprises a plurality of corresponding screw bosses 124 as well. The plurality of screw bosses 124 on both housing halves 104 and 106 are configured to allow removable coupling between the housing halves 104 and 106. The removable coupling between the housing halves 104 and 106 is by virtue of plurality of screws 126 inserted respectively screwed into the plurality of screw bosses 124 provided on the housing halves 104 and 106. Thereby, one screw 126 is inserted through one screw boss provided on the one housing half 104 (in FIG. 2 only the screw 126 is shown) and screwed into the corresponding screw boss 124 provided on the other housing half 106 (screw 126 and screw boss 124 illustrated in FIG. 2).

[0040] Further, the housing 102, in particular the first end 110, is fluidly coupled to the inlet 122. The inlet 122 comprises a sealing member 128, in particular an O-ring, held in a sealing groove 130, such that the inlet 122 is configured to be engageable in a sealing manner with the external liquid source.

[0041] Further, the watering device 100 comprises a water guiding part 132 mounted into the housing 102. Further, the water guiding part 132 fluidically connects the inlet 122 configured to guide the liquid into the watering device 100, with an outlet 134 configured to guide the liquid out of the watering device 100. The outlet 134 is located proximal to the second end 112 of the housing 102. In other words, the outlet 134 is positioned between the knob 118 and the spray head 114. Further, the outlet 134 comprises a sealing member 136, in particular an O-ring, held in a sealing groove 138, such that the outlet 134 is configured to be engageable in a sealing manner with the spray head 114. Further, the outlet 134 is at least partially disposed inside of the housing 102.

[0042] Further, the water guiding part 132 forms at least part of a connection between the inlet 122 and the outlet 134. According to an exemplary embodiment of the present invention as illustrated in FIG. 2, the water guiding part 132 forms the substantially entire fluid channel of the watering device 100 between the inlet 110 and the outlet 112. Further, the knob 118 is mounted to the water guiding part 132. Additionally, a valve and structures for functionally interacting with the trigger 116 are formed on respectively in the water guiding part 132. The housing halves 104 and 106 further comprises supporting structures to structurally support the water guiding part 132, the knob 118 and the trigger 116 inside the housing 102.

[0043] FIG. 3 illustrates a perspective view of a first section 140, a second section 142 and a further second section 144 of the water guiding part 132. The first section 140 and the second section 142 are integrally formed from the same material. Preferably, the material is an amorphous or semi-crystalline plastic, particularly ABS or PP. Further, the water guiding part 132 comprises the further second section 144. The further second section 144 is integrally formed with the first section 140 and the second section 142. The first section 140 is positioned in-between the second section 142 and the further second section 144. The first section 140, the second section 142 and the further second section 144 are formed such that, in a no frost condition, the first section 140 has a smaller radial extension than the second section 142 and the further second section 144. The first section 140 has a smaller radial extend than the second section 142 and the further second section 144. Particularly, seen in a side view as illustrated in FIG. 3, the further second section 144, the first section 140 and the second section 142 form a substantial double T profile In other words, the second section 142 and the further second section 144 are radially protruding relative to the first section 140 of the water guiding part 132. Further, when the water guiding part 132 is removably mounted within the housing 102, the further second section 144 is disposed proximal to the inlet 122. Hence, the further second section 144 is disposed between the inlet 122 and the first section 140.

[0044] Further, the second section 142 as well as the further second section 144 provide stability to the water guiding part 132, and the first section 140 provides frost compensation ability by changing its shape. The first section 140 may reversibly expand to compensate that frozen water inside the inner wall of the first section 140 and the second section 142 and the further second section 144 take up more volume than non-frozen water.

[0045] Furthermore, the first section 140, the second section 142 and the further second section 144 are integrally formed from the same material as a further water channel forming a flow channel of the watering device 100 in which downstream of the second section 142 the valve is formed and which is coupled at an opposite end to the spray head 114 (illustrated in FIG. 1).

[0046] FIG. 4 illustrates a cross-sectional view of the water guiding part 132. According to the exemplary embodiment as illustrated in FIG. 4, the inlet 122 is formed as an integral part of the water guiding part 132. The inlet 122 is configured to guide the liquid into the housing 102 and is positioned outside the housing 102 when the water guiding part 312 is mounted to the housing 102. The water guiding part 132 further comprises the first section 140 and the second section 142. The first section 140 comprises a first wall thickness T1, and the second section 142 comprises a second wall thickness T2, wherein the first wall thickness T1 is thinner than the second wall thickness T2. The first wall thickness T1 is set respectively chosen such that the first section 140 is reversibly expandable to compensate frost occurring in the water guiding part 132.

[0047] Additionally, the water guiding part 132 further comprises the further second section 144 that comprises a further second wall thickness T3, wherein the further second wall thickness T3 is thicker than the first wall thickness T1. The further second wall thickness T3 is set respectively chosen to provide stability to the water guiding part 132. The further second section 144 is formed on the water guiding part 132 such that the first section 140 is positioned in-between the second section 142 and the further second section 144. As illustrated the second wall thickness T2 and the further second wall thickness T3 are thicker than the first wall thickness T1 and are substantially equal.

[0048] During use of the watering device 100, when the liquid is required to be sprayed and therefore the trigger 116 is pressed, liquid flows from the external liquid source via the inlet 122 into and then through the water guiding part 132. Further, the liquid flows through the valve positioned inside the water guiding part 132 and to the spray head 114. Additionally, an amount of liquid may be adjusted by the knob 114 (illustrated in FIG. 1 and FIG. 2).

[0049] Further, during non-use of the watering device 100 and when the liquid left inside the water guiding part 132 freezes and undergoes an increase in volume due to freezing conditions, the first section 140 expands to accommodate the increased volume of the ice left in the water guiding part 132.
