Description

Technical Field

[0001] This utility model relates to the field of bathroom product technology, and more specifically, to an upward-flush foaming nozzle. Background Technology

[0002] Most existing top-flush foaming nozzles consist of multiple parts, resulting in complex structures and high costs. To address this, some top-flush foaming nozzles integrate air intake, water intake, and liquid intake into a single component to simplify the structure and reduce costs. For example, Chinese patent CN221760829U discloses a toilet foaming nozzle comprising a tube with a water inlet at one end and a water outlet at the other. The tube has a liquid inlet channel on its side wall and an air inlet on the same side wall, both located close to the water inlet. In this type of structure, due to the high degree of integration, the constricted section with the air inlet on the tube is not concentric with the water path to accommodate the liquid inlet pipe, causing uneven water flow and potentially splashing water onto the brush ring. Furthermore, to ensure effective air intake, the diameter of the constricted section must be made smaller, which reduces the flushing flow rate. Additionally, to avoid interfering with the insertion of the mounting nut, the liquid inlet pipe is short, making it prone to detachment. Utility Model Content

[0003] This utility model discloses an upward-flush foaming nozzle, which aims to improve the problems of existing upward-flush foaming nozzles such as easy water splashing around the brush ring, small upward flow rate, and easy detachment of the liquid inlet tube.

[0004] The present invention adopts the following solution:

[0005] An upward-flushing nozzle includes an upward-flushing body and a liquid inlet connector. The upward-flushing body has a water outlet channel extending from top to bottom and a constriction section located on the water outlet channel. The constriction section is concentrically arranged with the water outlet channel, and an air inlet and a liquid inlet are provided on the side wall of the constriction section. The liquid inlet connector has a connecting part and a liquid inlet channel. The liquid inlet connector is configured to connect to the upward-flushing body via the connecting part, so that the liquid inlet channel communicates with the liquid inlet.

[0006] As a further improvement, the outer wall of the upper punch body is provided with a locking part for adapting and connecting with the connecting part.

[0007] As a further improvement, the connecting part is a C-shaped elastic arm, and the locking part is a locking groove recessed along the outer wall of the upper punch body.

[0008] As a further improvement, one end of the liquid inlet channel is inserted into the liquid inlet, and the other end is used to connect to the liquid inlet pipe.

[0009] As a further improvement, an assembly flange is provided along the circumferential protrusion of the liquid inlet, and the outer end face of the assembly flange is not higher than the outer wall surface of the upper punch body.

[0010] As a further improvement, the water outlet end of the water outlet channel is equipped with a detachable nozzle, and the nozzle is provided with a nozzle for communicating with the water outlet channel.

[0011] As a further improvement, the end of the nozzle used to connect with the upper jet body is set as a ball head, and the upper jet body is provided with an arc-shaped groove corresponding to the ball head, so that the water outlet angle of the nozzle is adjustable.

[0012] As a further improvement, the upper punch body is provided with a first threaded portion, and the nozzle is connected and limited to the first threaded portion via a front nut.

[0013] As a further improvement, the bottom of the nozzle has a perforated baffle.

[0014] As a further improvement, the upper punch body is provided with a second threaded portion for connection with the mounting nut.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0016] In this application, water enters from the inlet of the outlet channel, flows through the contraction section, and utilizes the Venturi principle to draw in air, allowing external gas to enter the contraction section through the air inlet. At this time, the liquid inlet is also under negative pressure, allowing the foaming liquid to enter, thus achieving the mixing of water, air, and foaming liquid, forming a foam-mixed liquid that flows out from the outlet of the outlet channel. Compared to existing technologies, only one additional liquid inlet connector is needed to ensure that the contraction section and the outlet channel are concentrically aligned, avoiding water splashing from the brush ring. Simultaneously, the dimensions of the contraction section are guaranteed, ensuring the flushing flow rate and improving the flushing effect. Furthermore, the liquid inlet channel is located on the liquid inlet connector, eliminating the need to avoid other mounting components, ensuring the installation length of the liquid inlet pipe and channel, and preventing the liquid inlet pipe from detaching. During installation, the liquid inlet pipe can be connected to the liquid inlet connector first, and then installed to the flushing body, improving installation efficiency and further reducing the risk of the liquid inlet pipe detaching.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0031] Combination Figures 1 to 8 This embodiment provides an upward-flushing nozzle, including an upward-flushing body 1 and a liquid inlet connector 2. The upward-flushing body 1 has a water outlet channel 11 that runs through from top to bottom and a constriction section 12 located on the water outlet channel 11. The constriction section 12 is concentrically arranged with the water outlet channel 11, and an air inlet 121 and a liquid inlet 122 are provided on the side wall of the constriction section 12. The liquid inlet connector 2 is provided with a connecting part 21 and a liquid inlet channel 22. The liquid inlet connector 2 is configured to be connected to the upward-flushing body 1 via the connecting part 21 so that the liquid inlet channel 22 communicates with the liquid inlet 122.

[0032] It should be noted that in this embodiment, after the water enters from the inlet end of the outlet channel 11, it flows through the contraction section 12. Air is drawn in at the contraction section 12 using the Venturi principle, allowing external gas to enter from the air inlet 121. At this time, the liquid inlet 122 is also under negative pressure, allowing the foaming liquid to enter from the liquid inlet 122, thereby achieving the mixing of water, air, and foaming liquid, forming a liquid mixed with bubbles that flows out from the outlet end of the outlet channel 11. Compared with the prior art, only one additional liquid inlet connector 2 is needed to ensure that the contraction section 12 and the outlet channel 11 are concentrically arranged, thus avoiding the problem of water splashing from the brush ring. At the same time, the size of the contraction section 12 can be guaranteed, thereby ensuring the upward flushing flow rate and improving the flushing effect. Furthermore, the liquid inlet channel 22 is located on the liquid inlet connector 2, eliminating the need to avoid other installation components, thus ensuring the installation length of the liquid inlet pipe and the liquid inlet channel 22 and preventing the liquid inlet pipe from falling off. During installation, the inlet pipe can be connected to the inlet connector 2 first, and then installed to the upper flushing body 1 to improve installation efficiency and further reduce the risk of the inlet pipe falling off.

[0033] In a preferred embodiment, a locking part is provided on the outer wall of the upper punch body 1 for fitting and connecting with the connecting part 21. Specifically, the connecting part 21 is a C-shaped elastic arm, and the locking part is a locking groove 13 recessed along the outer wall of the upper punch body 1. During installation, after aligning the liquid inlet channel 22 with the liquid inlet 122, the elastic arm is inserted into the locking groove 13 to connect the liquid inlet connector 2 with the upper punch body 1, which is convenient for disassembly and assembly. This solves the problem of installing and fixing the liquid inlet pipe without affecting the assembly of the mounting nut 5, and does not occupy the water outlet channel 11, so that the contraction section 12 and the water outlet channel 11 are concentrically arranged, the water flow is smooth, the flow rate is large, the air intake is good, that is, the brush ring and the foaming effect are better, and water splashing is not easy.

[0034] In one embodiment, one end of the liquid inlet channel 22 is inserted into the liquid inlet 122, and the other end is used to connect to the liquid inlet pipe. For example, the liquid inlet pipe is a flexible hose, which is fitted onto the outer wall of the liquid inlet channel 22 for sealing. A mounting flange 1221 is provided along the circumferential protrusion of the liquid inlet 122, and the outer end face of the mounting flange 1221 is not higher than the outer wall surface of the upper punch body 1. The outer wall surface of the liquid inlet channel 22 and the inner side surface of the mounting flange 1221 are sealed together. The fact that the outer end face of the mounting flange 1221 is not higher than the outer wall surface of the upper punch body 1 can avoid interference between the mounting flange 1221 and the mounting nut 5, and facilitate the fitting of the mounting nut 5 onto the upper punch body 1.

[0035] Based on the above embodiments, in an optional embodiment of this utility model, the water outlet end of the water outlet channel 11 is equipped with a detachable nozzle 3, and the nozzle 3 is provided with a nozzle 31 for communicating with the water outlet channel 11. After the water flows into the water outlet channel 11, it mixes with gas and foaming liquid through the contraction section 12, and then forms bubble liquid that flows along the water outlet channel 11 to the nozzle 31. Preferably, the end of the nozzle 3 used to connect with the upper flushing body 1 is set as a ball head 32, and the upper flushing body 1 is provided with an arc-shaped groove corresponding to the ball head 32, so that the water outlet angle of the nozzle 31 is adjustable, which facilitates rinsing at different angles.

[0036] In one embodiment, the upper punch body 1 is provided with a first threaded portion 14, and the nozzle 3 is connected and limited to the first threaded portion 14 via a front nut 4, which facilitates disassembly and assembly. The bottom of the nozzle 3 has a perforated baffle 33 to allow the bubble liquid to be dispersed for further mixing, ensuring the mixing effect of the bubble liquid. In other embodiments, the upper punch body 1 is provided with a second threaded portion 15 for connection with the mounting nut 5. During installation, the mounting nut 5 is fitted onto the upper punch body 1 to connect with the second threaded portion 15, and then the liquid inlet connector 2 is installed to avoid interference between the liquid inlet connector 2 and the mounting nut 5.

[0037] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
