Description

Technical Field

[0001] The invention relates to the field of bubblers, and in particular to a self-cleaning bubbler capable of switching water sprays. Background Art

[0002] A bubbler is a device that creates a foaming effect and saves water. It allows the flowing water and air to mix fully, increasing the flushing force of the water flow while making the water flow soft and splash-free.

[0003] The water outlet of bathroom products such as faucets, spray guns, bidets, shower heads, etc. usually has a bubbler, which is used to provide corresponding bubble water or needle-shaped shower water according to different places of use, ensuring that users can provide comfortable and satisfactory washing effects in various situations. Most of the bubblers on the market that can be directly inserted into the threaded shell of the faucet mouth are single bubble water or single needle-shaped shower water. A small part of the bubblers that can switch the water splash feel tight and difficult to switch when the water pressure is high. It cannot meet the daily use of consumers. Some of them are switched by rotating the shell, or by pushing and pulling the shell up and down. The volume is large and cannot be inserted into the faucet shell. The appearance is not beautiful and it is very easy to leave stains and bacteria on the surface after use. The growth of bacteria during water use will cause cross-infection between users before and after. It cannot meet the hygiene needs. Summary of the invention

[0004] The purpose of the present invention is to address the deficiencies in the prior art and provide a self-cleaning bubbler with switchable water spray. The water spray direction can be controlled by the upstream water jet to enter a single or several water outlet cavities downstream of the water path, thereby achieving the effect of changing the water spray.

[0005] In order to solve the above technical problems, the following technical solutions are adopted:

[0006] A self-cleaning bubbler with switchable water spray comprises a bubbler shell, the interior of the bubbler shell is a cavity connected up and down, the upper part of the cavity is provided with a water inlet, the lower part of the cavity is provided with a water outlet, the middle part of the inner wall of the cavity is provided with a water outlet body and a nozzle, the top of the water outlet body is provided with a first water guide surface facing outwards, and the middle part of the water outlet body is provided with a through hole that runs through the entire water outlet body from top to bottom; the inner circle of the nozzle is provided with a second water guide surface facing outwards; when the second water guide surface is higher than the first water guide surface, the water flow is constrained by the first water guide surface, and the water flow is sprayed into the non-inner cavity of the water outlet body and then sprayed out; when the first water guide surface is higher than the second water guide surface, the water flow is constrained by the second water guide surface, and the water flow is sprayed into the inner cavity of the water outlet body and then sprayed out.

[0007] Furthermore, an inverted T-shaped middle guide rod is provided at the bottom end of the nozzle, and a water outlet net matching the outer cylindrical surface of the inverted T-shaped middle guide rod is provided on the inverted T-shaped middle guide rod.

[0008] Furthermore, a plurality of water outlet cavities are provided inside the water outlet body.

[0009] Furthermore, the water outlet body includes an external water outlet shell and an internal water outlet annular body, the inner cavity of the water outlet annular body is an inner water outlet cavity, the water outlet annular body and the water outlet shell form an intermediate water outlet cavity, and the water outlet body shell and the inner side of the nozzle form an outer water outlet cavity.

[0010] Further, the water outlet body is moved to the top so that the water outlet body is higher than the nozzle, and is constrained by the second water guide surface. The water flow channel formed by the nozzle and the water outlet body allows the water to be ejected from the inner water outlet cavity of the water outlet body; the water outlet body is moved to the middle so that the water outlet ring body and the nozzle of the water outlet body are level, and the water flows through the gap to form a jet and is ejected from the middle water outlet cavity of the water outlet body; the water outlet body is moved to the bottom so that the nozzle is higher than the water outlet body. Constrained by the first water guide surface, the water flow channel formed by the nozzle and the water outlet body allows the water to enter the outer water outlet cavity of the water outlet body and flow out with waterfall-like water splashes; or the water flows along the first water guide surface of the water outlet body into the outer water outlet cavity and the middle water outlet cavity of the water outlet body and discharges water at the same time.

[0011] Furthermore, the inner cavity of the water outlet body is an inner water outlet cavity, and the outer side of the water outlet body and the nozzle form an outer water outlet cavity.

[0012] Furthermore, the water outlet body is made higher than the nozzle and is constrained by the second water guide surface. The water flow channel formed by the nozzle and the water outlet body causes the water to be ejected from the inner water outlet cavity of the water outlet body; the nozzle is made higher than the water outlet body and is constrained by the first water guide surface. The water flow channel formed by the nozzle and the water outlet body causes the water to be ejected from the outer water outlet cavity of the water outlet body.

[0013] Furthermore, when a sealing ring is provided at the gap between the contact surfaces of the first water-conducting surface and the second water-conducting surface, the ejected water flow is a non-air-inhaling water spray.

[0014] Furthermore, when no sealing ring is provided at the gap between the contact surfaces of the first water-conducting surface and the second water-conducting surface, the ejected water flow is an air-inhaling water spray.

[0015] Furthermore, water outlet holes are evenly distributed on the outer edge of the water outlet body. When water flows into the outer water outlet cavity, it flows out through the water outlet holes as needle-shaped water splashes.

[0016] The above technical solution has the following beneficial effects:

[0017] The present invention is a self-cleaning bubbler with switchable water spray, which has a simple structure, is easy to use, has low cost and is easy to promote. The direction of the water jet from the nozzle is controlled by the relative displacement between the water outlet and the nozzle, so that the water jet enters the downstream of the water path, that is, a single or multiple water outlet cavities of the water outlet, thereby achieving the effect of changing the water spray with one bubbler.

[0035] Furthermore, a filter screen and a sealing gasket 1 are provided on the top of the bubbler housing, and the middle outer ring of the filter screen matches the inner ring of the sealing gasket 1 .

[0036] Embodiment 1:

[0037] Specifically, see Figure 8 In this embodiment, the water outlet body 3 includes an external water outlet shell and an internal water outlet annular body 35, the inner cavity of the water outlet annular body 35 is an inner water outlet cavity 31, the water outlet annular body 35 and the water outlet shell form an intermediate water outlet cavity 34, and the water outlet body 3 shell and the inner side of the nozzle 2 form an outer water outlet cavity.

[0038] Specifically, see Figure 3 The through hole of the water outlet and the inverted T-shaped intermediate guide rod 21 are provided with matching threads.

[0039] Furthermore, a sealing ring is provided at the gap between the contact surfaces of the first water guiding surface 32 and the second water guiding surface 22 .

[0040] Specifically, see Fig. 9 , the water outlet body 3 is rotated upward to the top so that the water outlet body 3 is higher than the nozzle 2, and is constrained by the second water guide surface 22. The water flow channel formed by the nozzle 2 and the water outlet body 3 allows the water to be ejected from the inner water outlet cavity 31 of the water outlet body 3.

[0041] Specifically, see Fig.10 , the water outlet body 3 is rotated upward to the middle, so that the water outlet ring body of the water outlet body 3 and the nozzle 2 are level, and the water flows through the gap to form a jet and is ejected from the middle water outlet cavity of the water outlet body.

[0042] Specifically, see Fig.11 , the water outlet body 3 is rotated upward to the bottom so that the nozzle 2 is higher than the water outlet body 3 and is constrained by the first water guide surface 32. The water flow channel formed by the nozzle 2 and the water outlet body 3 allows the water to enter the outer water outlet cavity of the water outlet body 3 and spray out, and flow out with waterfall-like water splashes; or the water flows along the first water guide surface of the water outlet body into the outer water outlet cavity and the middle water outlet cavity of the water outlet body and discharges water at the same time.

[0043] Specifically, see Figure 8 When water outlet holes are evenly distributed on the outer edge of the outer water outlet cavity, when water flows into the outer water outlet cavity, it flows out through the water outlet holes and needle-shaped water splashes.

[0044] Furthermore, no sealing ring is provided at the gap between the contact surfaces of the first water guiding surface 32 and the second water guiding surface 22 .

[0045] Specifically, the water outlet body 3 is rotated upward to the top so that the water outlet body 3 is higher than the nozzle 2 and is constrained by the second water guide surface 22. The water flow channel formed by the nozzle 2 and the water outlet body 3 allows water to flow from the inner water outlet cavity 31 of the water outlet body 3, and the outer water outlet cavity of the water outlet body inhales air from the outside. After the air and water are mixed, bubble water flows out from the inner water outlet cavity 31 of the water outlet body.

[0046] Specifically, the water outlet body 3 is rotated upward to the middle part so that the water outlet body 3 and the nozzle 2 are level, forming a gap perpendicular to the water outlet surface, and the water flows through the gap to form a jet and enter the middle water outlet cavity of the water outlet body. The outer water outlet cavity and the inner water outlet cavity 31 of the water outlet body inhale air from the outside, and the air and water flow are mixed to form oxygenated shower water flowing out from the middle water outlet cavity.

[0047] Specifically, the water outlet body 3 is rotated upward to the bottom so that the nozzle 2 is higher than the water outlet body 3 and is constrained by the first water guide surface 32.

[0051] Specifically, see Figure 7 , press the water outlet net 4 upwards, so that the water outlet body 3 is higher than the nozzle 2, and is constrained by the second water guide surface 22. The water flow channel formed by the nozzle and the water outlet body allows the water to be ejected from the inner water outlet cavity 31 of the water outlet body. At this time, due to the water pressure, the water outlet body 3 will not fall down.

[0052] Specifically, see Figure 6 , pull the water outlet body 3 downward so that the nozzle 2 is higher than the water outlet body 3, and is constrained by the first water guide surface 32. The water flow channel formed by the nozzle 2 and the water outlet body 3 causes the water to be ejected from the outer water outlet cavity of the water outlet body.

[0053] Specifically, see Figure 5 When water outlet holes are evenly distributed on the outer edge of the outer water outlet cavity, when water flows into the outer water outlet cavity, it flows out through the water outlet holes and needle-shaped water splashes.

[0054] Furthermore, no sealing ring is provided at the gap between the contact surfaces of the first water guiding surface 32 and the second water guiding surface 22 .

[0055] Specifically, the water outlet net 4 is pressed upwards to make the water outlet body 3 higher than the nozzle 2, and constrained by the second water guide surface 22, the water flow channel formed by the nozzle and the water outlet body causes the water to be ejected from the inner water outlet cavity 31 of the water outlet body, and the outer water outlet cavity of the water outlet body inhales air from the outside, and after mixing, bubble water flows out from the inner water outlet cavity of the water outlet body. At this time, due to the water pressure, the water outlet body 3 will not fall down.

[0056] Specifically, the water outlet body 3 is pulled downward so that the nozzle 2 is higher than the water outlet body 3 and is constrained by the first water guide surface 32. The water flow channel formed by the nozzle 2 and the water outlet body 3 causes the water to be ejected from the outer water outlet cavity of the water outlet body, and the inner water outlet cavity of the water outlet body inhales air from the outside, and after mixing, bubble water flows out from the outer water outlet cavity of the water outlet body.
