Description

Technical Field

This water outlet device can be applied to shower heads. To ensure the pulsed water flow effect of the oscillating channel, the length of the oscillating section cannot be too small. If this water outlet device is directly applied to a multi-level shower head, the existing structure of the water outlet device cannot be adapted for installation on a multi-level shower head because the internal structure of the multi-level shower head already occupies a lot of space. Therefore, it needs to be improved. Utility Model Content

Detailed Implementation

[0026] 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.

[0027] This utility model relates to a water outlet device, including a water inlet channel 100, an air intake chamber 200, and an oscillating channel 300.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, the inlet channel 100, the air intake chamber 200, and the oscillating channel 300 are sequentially connected. An air intake hole 210 is provided on the side wall of the air intake chamber 200, connecting the air intake chamber 200 to the external atmospheric environment. The oscillating channel 300 includes an oscillating section 310 and an oscillating chamber 320. The structures of the oscillating section 310 and the oscillating chamber 320 can utilize the structure disclosed in the water outlet device of application number 202411220925.7. A blocking part is provided in the oscillating channel 300 to obstruct the flow of some water towards the oscillating water outlet and to cause this portion of water to flow back towards the air intake chamber 200. When fluid flows from the inlet channel 100 to the air intake chamber 200, a negative pressure is created in the air intake chamber 200 through the Venturi effect, and the air intake chamber 200 draws in outside air through the air intake hole 210. The inlet channel 100 includes a first inlet, a second inlet section 120, and a throat section 130, which are sequentially connected. When fluid flows sequentially through the first inlet section 110, the second inlet section 120, the throat section 130, and the suction chamber 200, a Venturi effect is generated. The throat section 130, the suction chamber 200, and the oscillating section 310 are arranged along a third direction and are sequentially connected. The throat section 130, the suction chamber 200, and the oscillating section 310 can be coaxially integrally formed in the same straight pipe. The first inlet section 110 is arranged along a first direction, and the second inlet section 120 is arranged along a second direction. The first and second directions intersect, and the second direction intersects with the third direction. It is understandable that the first inlet section 110, the second inlet section 120, the throat section 130, the air intake chamber 200, and the oscillating section 310 can be located at the same horizontal position in space, and the oscillating chamber 320 can change direction at a 90° angle from the downstream end of the oscillating section 310. The transition point between the first inlet section 110 and the second inlet section 120 is set as an angle, and the transition point between the second inlet section 120 and the throat section 130 is set as an angle. Water flows in from the first inlet section 110, and flows sequentially along the first inlet section 110, the second inlet section 120, the throat section 130, the air intake chamber 200, and the oscillating channel 300. Air is drawn in by the air chamber, and the air enters the air intake chamber 200 for water-air mixing. Water flows directly from the air intake chamber 200 to the oscillating section 310, and then through the oscillating flow channel 300 to form a pulsed water output. The throat section 130, the air intake chamber 200, and the oscillating section 310 are distributed coaxially along the third direction, which can ensure that the water and air return achieves a pulsed effect.Compared to existing water outlet devices, when water flows through the inlet channel 100 of this invention's water outlet device, the relative directions between the first inlet section 110, the second inlet section 120, and the throat section 130 change along the same inlet water flow path as existing devices. This alters the straight-line distance between the beginning of the first inlet section 110 and the end of the oscillating section 310, reducing the length of the water outlet device. This ensures that the length of the oscillating section 310 is sufficient for the oscillating channel 300 to achieve pulsed water output, allowing the inlet channel 100 to be adapted for use in various water-using products. The intersection angles between the first, second, and third directions are determined based on the internal spatial shape of the water-using product into which the water outlet device is installed. This invention also relates to a shower head, with the water outlet device applied to it. For example... Figure 4 and Figure 5 As shown, the water outlet device is installed in the shower head housing 600. The first water inlet section 110 is connected to the shower head water inlet connector 610. The water inlet connector 610 is inserted into the water inlet section. The reverse arrangement of the first water inlet section 110 and the second water inlet section 120 offsets the orientation of the third direction of the oscillating section 310 from that of the water inlet connector 610, leaving enough space to meet the length setting of the first water inlet section 110 for assembly with the water inlet connector 610. At the same time, it allows the oscillating section 310 and the air intake chamber 200 to be set to a larger length along the third direction in the limited space of the shower head housing 600 to meet the pulse water output function of the oscillating flow channel 300.

[0029] In one embodiment, such as Figure 1 , Figure 2 and Figure 3As shown, the end of the oscillating section 310 furthest from the throat section 130 is the first end 311, which is the connection point between the oscillating section 310 and the oscillating cavity 320. The end of the second inlet section 120 closest to the throat section 130 is the second end 121, which is the connection point between the second inlet section 120 and the throat section 130. Spatially, from a top-down view, a circle 400 is formed with the center of the first end 311 as its center, and the center of the second end 121 is located on this circle 400. It should be noted that this circle 400 is only a virtual circle in space. The third direction and the first direction are located radially on the circle 400, but not on the same diameter. It can be understood that the distance from the center of the first end 311 to the center of the second end 121 is the radius of the circle 400. The water outlet device is located within the shower head housing 600. The first end 311 can be positioned at the center of the inner cavity of the housing 600. The design values ​​of the length dimensions of the air intake chamber 200 and the oscillating section 310 in the third direction can be maximized within the inner cavity of the housing 600. The second water inlet section 120 serves as a transitional section between the first water inlet section 110 and the air intake chamber 200. A larger central angle results in greater energy loss as water flows through the first water inlet section 110 and the second water inlet section 120 into the air intake chamber 200, weakening the air intake capacity and consequently reducing the pulse water flow effect. The central angle α formed between the third direction and the first direction is an acute angle, which helps control the energy loss of the water flow while maintaining the desired pulse water flow effect. Preferably, the central angle α formed between the third direction and the first direction is no greater than 40°. Within this angle range, excessive energy loss in the water flow channel 100 is avoided, ensuring the pulse water flow effect. The second water inlet section 120 extends in an arc shape along the circumference 400. Alternatively, the second water inlet section 120 can extend in a straight line tangent to the circumference 400, thus adapting to the internal shape of the shower head housing 600. Based on defining the angle range of the aforementioned circular angle, the extension direction of the second water inlet section 120 is further defined, that is, the intersection angle between the third direction and the second direction is defined.

[0030] In some specific embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the end of the first water inlet section 110 furthest from the second water inlet section 120 is the water inlet end 111. The shower head's water inlet connector 610 is inserted into the first water inlet section 110 from the water inlet end 111. The distance between the water inlet end 111 and the first end 311 is greater than the distance between the second end 121 and the first end 311. That is, the water inlet end 111 of the first water inlet section 110 extends radially outward from the center of the circumference 400 to the outer perimeter of the circumference 400, ensuring the extension length of the first water inlet section 110 for easy assembly with the water inlet connector 610.

[0031] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the water outlet device also includes a connecting part 500. The connecting part 500 can be integrally formed on the water outlet device. The first water inlet section 110 is formed on the connecting part 500. The connecting part 500 is also provided with a plurality of insertion channels 510 for connecting pipes. One, two or more insertion channels 510 can be provided. Each insertion channel 510 is used to connect with the water inlet connector 610 of the shower head. Each insertion channel 510 is paired and led out to the water flow channel of each setting of the shower head. The water outlet device is modularized and can be directly used after being installed in the shower head.

[0032] In some specific embodiments of this utility model, such as Figure 2 As shown, the minimum cross-sectional area of ​​the first inlet section 110 is greater than the maximum cross-sectional area of ​​the second inlet section 120, and the minimum cross-sectional area of ​​the second inlet section 120 is greater than the maximum cross-sectional area of ​​the throat section 130. The minimum cross-sectional area of ​​the air intake chamber 200 is greater than the maximum cross-sectional area of ​​the throat section 130. When the water flows sequentially through the first inlet section 110, the second inlet section 120, the throat section 130, and the air intake chamber 200, the water flow accelerates after flowing from the first inlet section 110 into the second inlet section 120. The water flow velocity is the maximum at the throat section 130. When the water flows into the air intake chamber 200, a negative pressure is formed in the air intake chamber 200, and external air is drawn in through the air intake hole 210. This creates a Venturi effect to cooperate with the oscillating flow channel 300 to form pulsed water output. The water flow cross-sectional areas of the air intake chamber 200 and the oscillation section 310 can be set to be equal, or the maximum water flow cross-sectional area of ​​the oscillation section 310 can be smaller than the minimum water flow cross-sectional area of ​​the air intake chamber 200.
