The invention discloses an anti-blocking bubbler which can automatically adjust water flowing quantity according to water pressure and effectively prevent blocking. The anti-blocking bubbler comprises a valve, an atomization device, a plurality of air inlets and a water retaining portion, wherein the valve is arranged at the water outlet end of a water outlet terminal, a longitudinal water flowing channel is formed in the middle of the valve, the atomization device is arranged at the water inlet end of the water flowing channel, the annular water retaining portion is arranged on a water outlet of the water flowing channel, and all the air inlets are distributed on the lateral wall of the valve in the radial direction and respectively connected with the water flowing channel. Therefore, water flowing into the water flowing channel forms an atomized water outlet effect through the atomization device, a part of atomized water sucks air through the air inlets and flows towards the center of the water outlet of the water flowing channel through the water retaining portion, and accordingly a water blocking surface is formed and totally blocks the water outlet of the water flowing channel. The other part of water breaks the formed water blocking surface to generate a water outlet bubbling effect, so that water outlet is gentle, water utilization convenience and comfortableness are improved, and further blocking can be effectively prevented.

The invention provides a faucet which comprises a base, a connecting pipe and a nozzle, wherein a connecting piece is arranged at an opening in the upper end part of the base; a first valve and a first switch for controlling the first valve are arranged on the base; the connecting pipe is connected with the base through the connecting piece; the nozzle comprises a T-shaped nozzle pipe; a second valve is arranged in the nozzle pipe; one end of the nozzle pipe is connected and fixed to the connecting piece; a second switch for controlling the second valve is arranged at the other end of the nozzle pipe; the second switch is a touch push switch; and the spout of the nozzle is formed in the end of the T-shaped nozzle pipe, which faces down. During a cleaning process, a user whose hands are busy can touch the second switch with an elbow or other parts to close the faucet; and the faucet has a simple structure, is highly humanized and is more convenient for people to use.

The invention discloses a water outflow rectifier. The water outflow rectifier can be inserted in a sleeve-shaped water outflow interface part with an external thread, the water outflow interface part is in matched connection with an internal thread of a drainage accessory through the external thread, the water outflow rectifier comprises a body, and at least one seal ring is arranged on a circumferential wall of the body and sealed in the radial direction between the water outflow rectifier and the water outflow interface part. The seal rings are sealed in the radial direction between the water outflow rectifier and the water outflow interface part, so that air and water are prevented from passing between the body and the water outflow interface part. The body does not need to be welded to the water outflow interface part and is convenient to install and dismantle and simple in structure. The seal rings can prevent external gas from entering a water pipe, water outflow bubble formation is avoided, water flows out softly, and the noise is small. The rectifier is long in service life, only a sealing element needs replacing if the sealing fails after use for a long time, and the rectifier is simple to operate and does not need replacing completely.

The invention discloses a shower head structure which comprises a square shower head body, a connector and multiple spray heads. The square shower head body is provided with a hollow cavity, and a water flow channel is arranged between every two adjacent spray heads; each spray head comprises a nozzle, a nozzle fixing block and a spray core, the bottom of the square shower head body is provided with installation holes for installing the nozzles, each nozzle fixing block is an annular fixing block provided with an internal thread, and the outer diameters of the annular fixing blocks are larger than the hole diameters of the installation holes; the upper end of each nozzle is provided with an external thread matched with the corresponding internal thread, each nozzle is internally provided with an installation cavity for installing the corresponding spray core, and the installation cavities are communicated with the water flow channels; a ball head is arranged on the top of the connector in an embedded mode, an inner sleeve is arranged in the ball head, the upper end of the inner sleeve is provided with a water inlet channel, the lower end of the water inlet channel is communicated with the water flow channels, and the side face of the ball head is provided with an air inlet hole communicated with the water inlet channel. According to the shower head structure, large-particle water drops can be generated, and a low-power high-efficiency shower effect can be achieved.

The invention relates to a novel method for firing Jianshui purple pottery. According to the invention, Jianshui purple pottery clay is prepared into a pottery; firing and polishing are carried out, such that a semi-finished product is obtained; the obtained semi-finished product is subjected to secondary firing; such that a finished product can be obtained. In the secondary firing process, the semi-finished product is placed in a dragon kiln or a gasification furnace kiln; the semi-finished product is covered with plant ash, and firing is carried out; when the firing temperature in the kiln is increased to 1140-1150 DEG C, heating is stopped; and after natural cooling, the finished product is obtained. With the method provided by the invention, purple pottery products with rich and varied colors, sparkling crystals formed on the surface, and moist and jade-like hand feeling can be obtained. Tea infused in the purple pottery is sweeter.

The invention discloses a preparation method of original strong-flavor oolong tea, Tieguanyin. The method comprises the following steps: picking green tea leaves, sunning the green tea leaves, rocking the green tea leaves, performing fine manipulation on the green tea leaves, frying the green tea leaves, rolling the green tea leaves and baking the green tea leaves. According to the method, the rolled tea leaves do not need to be wrapped and twisted, so that the tea leaves are made into strip-shaped tea leaves and the tea fragrance relatively easily permeates into the tea leaves during baking; after the tea leaves are baked for three times, the tea fragrance permeates into the tea leaves and the tea leaf quality is ensured; the tea is long in usage and storage time at normal temperature, and the brewing frequency of the tea at least can be increased to more than 10 times; the tea leaves are baked after being annealed, so that the tea fragrance and the charcoal fire fragrance further permeate into the tea leaves, tea made by the tea leaves is relatively soft and smooth, and the tea soup quality is ensured; the tea leaves are rocked for four times, so that the completeness of the leaves can be retained, the tea leaves are relatively uniformly fermented, the fragrance is relatively rich, and the taste is relatively lasting; the tea leaves are kept in a static state for one time after being rocked each time, so that water of the fresh leaves can be conveniently drained and good fragrance can be generated when the tea leaves are in the static state.
