Description

Technical Field

[0001] This utility model relates to the field of water outlet equipment technology, and in particular to a water outlet nozzle and a water outlet device using the same. Background Technology

[0002] Some existing water nozzles have a strip-shaped outlet. This outlet elastically opens according to water pressure. To ensure good water impact even at low water pressure, the initial width of the outlet needs to be less than 0.3mm. This initial width needs to be determined during injection molding. This necessitates a long and thin mold core. According to mold manufacturers' experience, when the core width is less than 0.3mm, not only is burr formation during molding prone to occur, leading to low yield, but the mold life is also short, and the core is easily damaged. If the water outlet is cut using a die-cutting tool, the outlet is a blind hole during molding. While the cut hole can be very small, the soft silicone makes accurate positioning difficult during secondary processing, often resulting in misalignment and poor water flow. Utility Model Content

[0003] The present invention aims to at least partially solve one of the aforementioned technical problems in the related art. To this end, the present invention proposes a water outlet.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] This utility model also proposes a water outlet device having the above-mentioned water outlet nozzle.

[0006] According to a first aspect of the present invention, a water outlet includes a main body and a connecting part. The main body and the connecting part are integrally formed and both are elastic. The main body is provided with a water passage and an inlet and an outlet located at both ends of the water passage. The outlet can elastically open and close under water pressure. The circumferential outer wall of the main body is connected to the connecting part. The connecting part can elastically deform relative to the main body and squeeze the main body inward to reduce the water passage cross-sectional area of ​​the outlet.

[0007] The water outlet nozzle according to the present utility model embodiment has at least the following beneficial effects: during production, the size of the water outlet can be set to a larger size, and then during installation, the cross-sectional area of ​​the water outlet can be reduced through structural and assembly technology, thereby greatly reducing the difficulty of the water outlet nozzle molding process, ensuring the strength of the mold, and improving the production yield.

[0008] According to some embodiments of the present invention, the connecting portion includes a substrate and an extrusion portion. The substrate extends from a first side to a second side along its thickness direction. The first side is closer to the outlet than the second side. The extrusion portion is formed on the substrate and surrounds the main body and is connected to the outer wall of the main body. The direction from the first side to the second side is the first direction, and the direction from the second side to the first side is the second direction. The extrusion portion protrudes from the first side along the second direction. When the main body is pulled by an external force along the first direction, both the main body and the extrusion portion can move relative to the substrate along the first direction. The extrusion portion undergoes elastic deformation and extrudes inward against the main body.

[0009] According to some embodiments of the present invention, the extrusion portion is recessed along the second direction on one side of the second side to form a groove.

[0012] According to some embodiments of the present invention, the cross-section of the water outlet has a length dimension and a width dimension, the length dimension being greater than the width dimension. When the main body and the connecting part are not subjected to external force, the width dimension is in the range of 0.3mm to 0.6mm; when the main body and the connecting part are subjected to external force, the main body is squeezed inward until the width dimension of the water outlet is less than 0.3mm.

[0013] According to some embodiments of this utility model, the cross-section of the water outlet is strip-shaped, dumbbell-shaped, or elliptical.

[0014] A water outlet device according to a second aspect of the present invention includes a water outlet nozzle.

Detailed Implementation

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] This utility model relates to a water outlet, including a main body 100 and a connecting part 200.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the main body 100 and the connecting part 200 are integrally formed, and the entire spout can be made of elastic materials such as rubber or silicone. Both the main body 100 and the connecting part 200 are elastic and can undergo elastic deformation. The main body 100 is provided with a water passage 110, with an inlet 120 and an outlet 130 at its two ends. External water can flow into the water passage 110 through the inlet 120, and the water is sprayed out through the outlet 130. The outlet 130 can elastically open and close under the water pressure inside the water passage 110, thereby changing the cross-sectional area of ​​the outlet 130. When the water pressure in the water passage 110 is high, the outlet 130 opens in the direction of expanding deformation, the cross-sectional area of ​​the water passage increases, and the impact force of the water outlet decreases relatively. When the water pressure in the water passage 110 is low, the outlet 130 contracts in the direction of shrinkage, reducing the cross-sectional area and increasing the water impact force. The water impact force is automatically adjusted by the opening and closing of the outlet 130. The circumferential outer wall of the main body 100 is connected to the connecting part 200. For example... Figure 4 As shown, when an external force is applied between the main body 100 and the connecting part 200, the connecting part 200 can elastically deform relative to the main body 100. When the connecting part 200 deforms, it applies a compressive force to the outer wall of the main body 100. After being compressed, the main body 100 undergoes elastic deformation, causing the outlet 130 to contract, resulting in a reduction in the water passage cross-sectional area of ​​the outlet 130. In actual use, the water nozzle is used in conjunction with water-using equipment. This utility model also relates to a water outlet device that utilizes the aforementioned water nozzle. Figure 5 , Figure 6 and Figure 7 As shown, the water outlet device can be a shower head, overhead spray, etc. The water nozzle is installed in the water outlet device, and the internal components of the device fix the nozzle and apply a force to it, causing the connecting part 200 to elastically deform and compress the main body 100, thus reducing the size of the water outlet 130. If the external force applied to the nozzle by the water outlet device remains constant, before water flows through the water passage 110, the water outlet 130 remains in a deformed state with a fixed cross-sectional area. At this time, the cross-sectional area of ​​the water outlet 130 is at its minimum before and after water flows through the water passage 110. After water flows through the water passage 110, the water outlet 130 opens as the water pressure increases or contracts as the water pressure decreases.

[0030] During production, the spout can be manufactured using a mature liquid injection molding process. Initially, the dimensions of the spout 130 are set to a relatively large size, for example, its width is set at 0.3mm-0.5mm. Then, during installation, through structural and assembly techniques, the water passage cross-sectional area of ​​the spout 130 is reduced to below 0.3mm. This means the initial water outlet cross-sectional area of ​​the spout 130 is reduced from a large area to a small area. Simultaneously, based on the inherent elasticity of the spout, the spout 130 can automatically adjust the water filling impact force according to the water pressure. This greatly reduces the molding difficulty of the spout. When not installed, the width of the spout 130 can be between 0.3mm and 0.5mm, ensuring the strength of the mold and improving the production yield. After installation, the width of the spout 130 can be reduced to between 0-0.3mm. Even when the water pressure in the water passage 110 is low, the spout 130 can still maintain a good impact force.

[0031] In one embodiment, such as Figure 3 and Figure 4As shown, the connecting portion 200 includes a substrate 210 and an extrusion portion 220. The substrate 210 is plate-shaped and extends from a first side surface 211 to a second side surface 212 along its thickness direction. In the illustrated direction, the lower side surface of the substrate 210 is the first side surface 211, and the upper side surface is the second side surface 212. The direction from the first side surface 211 to the second side surface 212 is defined as the first direction, i.e., the upward direction in the illustration is the first direction. The direction from the second side surface 212 to the first side surface 211 is defined as the second direction, i.e., the downward direction in the illustration is the second direction. The extrusion portion 220 is formed on the substrate 210 and is disposed around the main body 100. The substrate 210 is connected to the outer wall of the main body 100 through the extrusion portion 220. The first side surface 211 is closer to the outlet 130 than the second side surface 212. The inlet 120 is located above the second side surface 212, and the outlet 130 is located below the first side surface 211. Under normal conditions, the pressing part 220 protrudes downward from the first side surface 211 in the second direction. When the main body 100 is pulled by an external force in the first direction, the main body 100 can move upward relative to the base plate 210, and at the same time, the pressing part 220 is moved upward by the main body 100. When the pressing part 220 moves, it undergoes elastic deformation, thereby applying an inward pressing force to the main body 100, causing the outlet 130 to shrink. The water outlet is fixed in the water outlet device by the base plate 210. With the base plate 210 as a support, the components inside the water outlet device clamp or fix the main body 100 in other ways, and at the same time, they will generate an upward pulling force in the first direction on the main body 100, pulling the main body 100 upward relative to the base plate 210. The deformation of the pressing part 220 applies a pressing force to the main body 100, and after installation, the outlet 130 shrinks to its minimum value. Among them, the pressing part 220 is recessed in the second direction on one side of the second side surface 212 to form a groove 230. As shown in the diagram, a groove 230 is formed on the upper side of the extrusion portion 220, and the groove 230 extends around the main body 100. When the main body 100 moves upward relative to the connecting portion 200, the extrusion portion 220 moves upward accordingly. The protrusion of the extrusion portion 220 relative to the first side surface 211 decreases, and the indentation of the groove 230 decreases. The thickness of the extrusion portion 220 can be set to be smaller than the thickness of the substrate 210. After the extrusion portion 220 moves upward, the radial direction of the extrusion portion 220 is supported by the substrate 210, causing the extrusion portion 220 to extrude radially against the main body 100, thereby causing the outlet 130 to contract.

[0032] The main body 100 has a raised edge 140 on its circumferential outer wall. The raised edge 140 can be positioned close to the water inlet 120. The raised edge 140 is opposite to the groove 230, with the groove 230 opening upwards towards the raised edge 140, forming a snap-fit ​​position 150 between the raised edge 140 and the groove 230. In actual installation, if... Figure 7As shown, the water outlet device also includes a retaining plate 300. The connecting portion 200 may be provided with multiple main bodies 100. The retaining plate 300 has multiple retaining holes 310. The shape of the retaining holes 310 is adapted to the main body 100. Each main body 100 is paired and passes through the retaining hole 310, and the main body 100 is engaged with the retaining hole 310. Specifically, the sidewall of the retaining hole 310 is engaged in the engaging position 150. The lower side of the retaining plate 300 abuts against the base plate 210, and the upper side abuts against the protruding edge 140. After engagement, the retaining plate 300, supported by the base plate 210, applies an upward external force (tension) to the main body 100 using the protruding edge 140, thereby causing the main body 100 to move upward relative to the base plate 210, which in turn causes the pressing portion 220 to deform and press the main body 100.

[0033] In one embodiment, such as Figure 3 and Figure 4 As shown, the main body 100 includes a pulling part 160 and a water outlet part 170. The pulling part 160 and the squeezing part 220 are vertically distributed in the direction shown. A water passage 110 passes through the pulling part 160 and the water outlet part 170. A water inlet 120 is located at the upper end of the pulling part 160, and a water outlet 130 is located at the lower end of the water outlet part 170. A connecting part 200 is connected to the outer wall of the water outlet part 170. The water outlet part 170 is constricted, gradually narrowing along the water flow direction. The water flow direction in the water passage 110 is from the water inlet 120 to the water outlet 130, and the water outlet part 170 gradually narrows from the water inlet 120 to the water outlet 130. Both the outer and inner walls of the water outlet part 170 can be conical. When the main body 100 moves upward relative to the substrate 210, the extrusion part 220 deforms in conjunction, and the extrusion force of the extrusion part 220 on the water outlet 170 has a component force perpendicular to the side wall of the water outlet 170, thereby compressing the water outlet 130.

[0034] Among them, such as Figure 1 and Figure 3As shown, the cross-section of the outlet 130 has a length dimension A and a width dimension B. The length dimension is greater than the width dimension. The length dimension can be set to 4 mm to 5 mm. When there is no external force acting between the main body 100 and the connecting part 200, the width dimension is in the range of 0.3 mm to 0.6 mm. The width dimension can be, but is not limited to, 3 mm, 3.2 mm, 3.5 mm, 3.8 mm, 4 mm, 4.5 mm, 4.7 mm, 5 mm, 5.5 mm, 6 mm, etc. Within this width dimension range, it is convenient to form the outlet 130 during production, reduce the production process, and also facilitate the shrinkage of the outlet 130 to the required size after the main body 100 is compressed. When the main body 100 and the connecting part 200 are subjected to external force, the main body 100 is squeezed inward until the width of the outlet 130 is less than 0.3 mm, which can be 0.29 mm, 0.25 mm, 0.22 mm, 0.2 mm, 0.15 mm, 0.1 mm, 0.05 mm, 0 mm, etc. That is, when the main body 100 is squeezed by the connecting part 200 but there is no water pressure in the water passage 110, the width of the outlet 130 is less than 0.3 mm. The cross-section of the outlet 130 can be strip-shaped, dumbbell-shaped, or elliptical, etc.
