Description

Intelligent toilet bowl is shower nozzle for purger

Technical Field

The utility model belongs to the technical field of intelligence bathroom, specific shower nozzle for intelligent toilet bowl purger that says so.

Background

Various nozzle forms have appeared on the intelligent toilet bowl (closestool) products sold in the market at present, and one or more nozzle holes can be arranged on the spray rod to realize different functions, such as hip washing, female washing and the like. When the single spray hole is adopted for cleaning, columnar jet flows out of the spray hole, the columnar jet is generally broken into a queue consisting of liquid drops with larger size than the spray hole before reaching a human body, and the liquid drops impact the human body to achieve the purpose of cleaning. The mode has small cleaning area and large impact force, and is easy to cause stabbing pain in local sensitive areas of human bodies. In order to increase the cleaning area, many products use a plurality of orifices to form an array, increasing the area of the outlet, and in this case the orifices are small in size and are prone to flow loss and orifice blockage. In addition, the jet cleaning area is too large, and the impact force is small. The spraying rod of the intelligent toilet is generally designed with a transmission device, so that the spraying rod can move along an axis to extend and retract. With the transmission mechanism, the spray rod can move back and forth along the axis, the cleaning area along the front and the back of the human body is increased, and the cleaning area along the left and the right of the human body cannot be changed. It is necessary to develop a method for improving the distribution of the water jet in the left and right directions, so as to apply the prior mature technology to the maximum extent, simplify the design of the spray head and improve the user experience. Further, if the form of water acting on the human body can be changed, for example, from a water film to discrete water droplets, it is possible to satisfy the conditions of sex, age, sensitivity, personal preference, disease, post-operation, and the like.

In the invention patent of CN 108301477 a patent application publication No. CN 108301477 a intelligent toilet nozzle structure for local large area cleaning and an intelligent toilet using the same, an intelligent toilet nozzle structure for local large area cleaning is disclosed, which adopts a widely used slit type fan-shaped nozzle structure to form a long strip-shaped local large area cleaning region along the front-back direction, thereby realizing linear human body cleaning without front-back movement. This slit fan nozzle design does not achieve a distribution of the water flow acting on the human body in the left-right direction and requires a high pressure to achieve the desired atomization.

In the invention patent "an intelligent toilet nozzle structure for realizing dispersed cleaning" with application publication number CN 108355846 a, a through hole is arranged on the top wall of the flow guiding chamber, a dispersing piece is arranged at the through hole to form an annular dispersed water jet, and cleaning water is annularly and dispersedly sprayed out from the dispersed water jet. The center of the spray is air, the flow loss caused by adding the dispersion piece is large, the obtained spray is too fine, and the action force with the human body is small.

Utility model "a sprinkler for intelligent closestool" that the authorization notice number is CN 205935127U has proposed a waving water mechanism, utilizes water conservancy diversion cavity and swing fluid cavity to realize the back and forth swing play water of single strand rivers, carries out the washing of pulse massage form, improves user experience. The scheme needs an additional design mechanism, the reliability and the production cost are controlled, the cleaning area is small at any time, and the cleaning range along the left and right directions of the human body is narrow. The flow path through which the water passes has a constricted and expanded shape and a plurality of corners, causing unnecessary flow loss, and the assembly is also easily damaged. Clogging and poor local water circulation are easily caused, resulting in bacterial growth.

In the invention patent of CN 109653324 a, an intelligent toilet nozzle and an intelligent toilet spray gun, an intelligent toilet nozzle is disclosed, which comprises a nozzle body, a water flow channel and a rectifying chamber are arranged in the nozzle body, the rectifying chamber is provided with a rectifying piece, and the rectifying piece and the water flow channel and the rectifying chamber form a water inlet chamber, a water guide chamber, a converging chamber and a water outlet chamber which are sequentially communicated, so that water flow is sprayed out in a swinging manner at an outlet. The structure proposed by the invention is complex, additional design and manufacture are needed, the reliability and the control of the production cost are difficult, and the cleaning area is small at any time. The flow path through which the water passes has a constricted and expanded shape and a plurality of corners, causing unnecessary flow loss, and the assembly is also easily damaged. Clogging and poor local water circulation are easily caused, resulting in bacterial growth.

The invention patent CN 1103917A discloses a sanitary cleaning device, which designs two groups of spray holes with axes forming a certain included angle to enable water flow to cross between a spray end face and a cleaning face, and generates turbulence or air mixing by means of a turbulence generating device in a water flow channel to enable the sprayed cross water flow to be unbalanced in the vertical direction, thereby generating irregular change and enabling the spray flow to swing. If the water flow has no turbulence or is not mixed with air, the vertical component forces of the jet flows after the cross convergence are respectively balanced, and the jet flows become concentrated stable water flows and are sprayed to the local part of the human body. In addition, the swinging of the jet can be realized by controlling the water quantity proportion of the two crossed water flows, and the cleaning jet flow can be moved under the condition that the cleaning nozzle does not move. The nozzle in this technique has many openings, and 4 or 5 openings are used. In addition, the water flow acted on the human body by the improved technology is still a concentrated jet flow, which is easy to cause stabbing pain.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

As shown in fig. 1 and 2, the nozzle for the intelligent toilet cleaner comprises two pipes which are coaxially arranged, namely an outer pipe 1 and an inner pipe 2; one end of the outer tube 1 is closed and is a closed end, and the other end of the outer tube is an open end; the inner pipe 2 slides along the axis in the outer pipe 1; the pipe wall of the closed end of the outer pipe 1 is provided with two spray holes, namely a first spray hole 3 and a second spray hole 4; an included angle formed between the first spray hole 3 and the second spray hole 4 at the outer side of the pipe wall is an acute angle;

the cleaning spray head is composed of an outer pipe 1 and an inner pipe 2 which are nested with each other. Two spray holes, namely a first spray hole 3 and a second spray hole 4 are arranged on the side wall of the outer tube 1, the first spray hole 3 and the second spray hole 4 form a certain angle, and the specific numerical value of the angle is determined according to experimental research and user experience. The first spray hole 3 is close to the closed end, and the second spray hole 4 is close to the open end;

in the first working state as shown in fig. 1, the inner tube 2 seals the second nozzle 4, and the washing water is ejected from the first nozzle 3, is broken into droplets before reaching the human body, and finally acts on the human body in the form of a droplet queue. In a second operating state, as shown in fig. 2, the inner tube 2 moves toward the open end, water is ejected from both the first nozzle hole 3 and the second nozzle hole 4, and the two formed jets collide with each other before breaking.

Depending on the flow rate, three modes may occur as shown in fig. 3a to 3 c. When the speed is relatively low, as shown in fig. 3a, the two angled jets converge into one oscillating jet; when the velocities are appropriate, as in fig. 3b, the two angled jets form a liquid film on the impingement surface; when the velocity is high, as in fig. 3c, the liquid film formed by the two angled jets destabilizes in the air and thereby oscillates back and forth, atomizing the cleaning water into a spray of small droplets.
