Description

Technical Field

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

[0002] A bubbler refers to a device that can make water flow foam and save water. The bubbler can fully mix the flowing water and air, improving the water flow scouring force while making the water outlet gentle without splashing.

[0003] At the water outlet terminals of sanitary wares such as faucets, spray guns, bidets, and shower heads, a bubbler is usually provided, which is used to provide corresponding bubble water or needle-shaped sprinkler water according to different usage places to ensure a comfortable and satisfactory washing effect for users in various situations. Most of the bubblers on the market that can be directly inserted into the threaded housing of the faucet mouth are either single bubble water or single needle-shaped sprinkler water. A small number of bubblers that can switch water sprays use a rubber sealing structure, which has a tight and astringent feel, and it is difficult to switch when the water pressure is relatively high. It cannot meet the daily use needs of consumers. Some are switched by rotating the outer shell or pushing and pulling the outer shell up and down. They are relatively large in size and cannot be inserted into the faucet housing. Their appearance is not beautiful, and stains and bacteria are extremely likely to remain on the surface after use. Bacterial growth during water use will cause cross-infection between the previous and subsequent users. It cannot meet the hygiene requirements. Summary of the Invention

[0004] The purpose of the present invention is to provide a self-cleaning bubbler capable of switching multiple water sprays in view of the deficiencies of the prior art, which can control the upstream water jet direction so that it enters one or several separate water outlet cavities in the downstream of the water path, thereby achieving different water spray effects.

[0005] To solve the above technical problems, the following technical solutions are adopted:

[0006] A self-cleaning bubbler capable of switching multiple water sprays includes a bubbler housing. The interior of the bubbler housing is a cavity that is connected up and down. An inlet is provided at the upper part of the cavity, and an outlet is provided at the lower part of the cavity. A nozzle and a water guide body are provided in the middle of the inner wall of the cavity. The water guide body is arranged inside the nozzle. An inward water guide surface is provided at the inner ring opening of the nozzle as the first water guide surface, and the outer surface of the head of the water guide body is the second water guide surface; when the bottom end of the head of the water guide body is higher than the first water guide surface at the bottom end of the nozzle, restricted by the first water guide surface, the water flow jets into the inner cavity of the water outlet body and then jets out; when the bottom end of the head of the water guide body is lower than the bottom end of the nozzle, restricted by the second water guide surface, the water flow jets into the non-inner cavity of the water outlet body and then jets out.

[0007] Further, the water guiding body includes a water guiding block at the upper part and an intermediate guide rod at the lower part. A plurality of ratchet teeth are provided at the connection between the intermediate guide rod and the water guiding block, and the plurality of ratchet teeth are evenly distributed on the top of the outer cylinder of the intermediate guide rod.

[0008] Further, a push rod head matching the outer cylindrical surface of the intermediate guide rod is provided at the lower part of the intermediate guide rod. An outlet water net is fixedly connected to the lower part of the push rod head, and the upper outer cylindrical surface of the push rod head matches the water outlet body.

[0009] Further, the water outlet body further includes an outer water outlet housing and a middle water outlet ring body in the middle. An outer water outlet cavity is formed between the water outlet housing and the water outlet ring body, and an inner water outlet cavity is formed between the water outlet ring body and the water outlet installation ring body.

[0010] Further, the water outlet body includes an inner water outlet installation ring body. Tooth grooves are arranged at high and low intervals in the water outlet installation ring body. The tooth grooves include high tooth groove positions and low tooth groove positions. When the ratchet teeth are stuck in the high tooth groove positions, the water flow channel formed by the nozzle and the water guiding body makes the water spray out from the inner water outlet cavity of the water outlet body. The outer water outlet cavity of the water outlet body inhales air from the outside, and after mixing, bubble water flows out from the middle of the inner water outlet cavity of the water outlet body; when the ratchet teeth are stuck in the low tooth groove positions, the water flow channel formed by the nozzle and the water guiding body makes the water spray out as sprinkler water from the outer water outlet cavity of the water outlet body.

[0011] Further, the water guiding body includes a water guiding block at the upper part and an intermediate guide rod at the lower part. A spiral tooth groove is provided on the intermediate guide rod, and the spiral tooth groove matches the inside of the water outlet body.

[0012] Further, a rotating handle matching the outer cylindrical surface of the intermediate guide rod is provided at the lower part of the intermediate guide rod, and an outlet water net matching the outer cylindrical surface of the intermediate guide rod is provided at the middle and lower parts of the intermediate guide rod.

[0013] Further, the water outlet body further includes an outer water outlet housing, a middle water outlet ring body in the middle and an inner water outlet installation ring body inside. An outer water outlet cavity is formed between the water outlet housing and the water outlet ring body, an inner water outlet cavity is formed between the water outlet ring body and the water outlet installation ring body, and a middle water outlet cavity is formed between the water ring body and the water outlet installation ring body.

[0014] Further, a spiral groove is provided inside the inner water outlet cavity. When the water guide body is rotated upward to a high position by rotating the handle, the second water guide surface of the water guide body is higher than the first water guide surface of the nozzle. Water flows along the first water guide surface into the inner water outlet cavity of the water outlet body. The outer water outlet cavity of the water outlet body inhales air from the outside, and after mixing, bubble water flows out from the middle of the inner water outlet cavity of the water outlet body. When the water guide body is rotated upward to the middle position by rotating the handle, the water guide body is flush with the nozzle, forming a gap perpendicular to the water outlet surface. Water flows through the gap to form a jet and enters the middle water outlet cavity of the water outlet body. The outer water outlet cavity and the inner water outlet cavity of the water outlet body inhale air from the outside, and after mixing, oxygenated sprinkler water flows out from the middle water outlet cavity. When the water guide body is rotated downward to a low position by rotating the handle, water flows along the second water guide surface of the water guide body into the outer water outlet cavity of the water outlet body and needle-shaped sprinkler water flows out; or water flows along the second water guide surface of the water guide body into the outer water outlet cavity and the middle cavity of the water outlet body to discharge water simultaneously.

[0015] Further, a filter screen and a sealing gasket are provided at the top of the bubbler housing, and the outer ring of the middle part of the filter screen matches the inner ring of the sealing gasket.

[0016] Due to the adoption of the above technical solutions, the following beneficial effects are achieved:

[0017] The present invention is a self-cleaning bubbler that can switch between multiple water sprays. By arranging a water guide body inside the nozzle at the upstream of the water path, the relative displacement between the water guide body and the nozzle is used to control the water jet direction of the nozzle, so that it enters a single or multiple water outlet cavities downstream of the water path, thereby achieving the effect that different water sprays can be realized by one bubbler.
