Toilet flushing nozzle with Venturi effect

A Venturi effect and toilet technology, which is applied in flushing toilets, water supply devices, buildings, etc., can solve problems such as the inability to greatly increase the sewage discharge speed of the toilet sewage pipe, the inability to fully exert the water pressure, and poor sewage discharge effect of the toilet, etc. , to achieve the effect of improving water utilization, increasing flow rate and reducing water resistance

Problems solved by technology

[0002] The toilet is the main cleaning and sanitary appliance in the bathroom. According to the principle of flushing, it is divided into two categories: the flush type and the siphon type. It is sprayed out to form a stream of flushing water sprayed against the sewage outlet in the opposite direction to the side wall of the water seal tank at the bottom of the urinal. The nozzle suddenly reduces the flow cross-section, so that the flow velocity and momentum of the water sprayed by the nozzle increase, and the flow of the nozzle suddenly shrinks. The resistance coefficient of the cross section to the downflush water is relatively l

Embodiment 1

[0027] as attached figure 1 to attach Figure 7 As shown, the present invention provides a toilet flushing nozzle with Venturi effect, which is installed on the side wall of the water seal tank of the toilet and can be sprayed and flushed towards the sewage outlet, including: a water inlet for pressure water to flow in An end cover 0 and a sleeve 3 installed on the side wall of the water seal tank, and the water inlet end cover 0 is connected to the inner side of the sleeve 3;

[0028] A Venturi tube 1 is also installed in the space where the water inlet cover 0 and the casing 3 are connected. the outermost end of tube 3;

[0029] When the Venturi tube 1 is working, a negative pressure is generated between the outer wall of the Venturi tube 1 and the inner wall of the sleeve 3, so that the water between the outer wall of the Venturi tube 1 and the inner wall of the sleeve 3 is sucked into the Venturi tube 1 and then discharged.

[0030] as attached figure 1 As shown, the V...

Embodiment 2

[0037] On the basis of embodiment 1, as attached Figure 7 As shown, the booster pipe 10 in the Venturi tube 1 can be integrally formed and connected with the water inlet cover 0, and the nozzle expander 11 in the Venturi tube 10 is spaced from the inner wall of the casing 3 and integrally formed to form a Venturi effect. The cavity achieves the same effect as that of Embodiment 1, and the integrally formed structure is more concise, easier to assemble, and the difficulty of product injection molding is reduced, reducing production costs.

Abstract

The invention discloses a toilet flushing nozzle with a Venturi effect. A Venturi tube is further mounted in a space where a water inlet end cover is connected with a sleeve, the water inlet end of the Venturi tube is communicated with the water inlet end cover, and the water outlet end of the Venturi tube is exposed out of the outermost end of the sleeve. The present invention can utilize the water in a water seal tank, water flowing into the water seal tank is pumped through negative pressure formed by the Venturi tube and converged with accelerated pressure water to form converging water, at the moment, the flow speed of the converging water is large, the water amount is increased, the water flow impact surface is enlarged, excrement can be washed more cleanly, the water amount of the water seal water is utilized, and the utilization rate of the water during washing is increased.

Description

technical field [0001] The invention relates to a toilet in the field of sanitary ware, in particular to a toilet flushing nozzle with Venturi effect. Background technique [0002] The toilet is the main cleaning and sanitary appliance in the bathroom. According to the principle of flushing, it is divided into two categories: the flush type and the siphon type. It is sprayed out to form a stream of flushing water sprayed against the sewage outlet in the opposite direction to the side wall of the water seal tank at the bottom of the urinal. The nozzle suddenly reduces the flow cross-section, so that the flow velocity and momentum of the water sprayed by the nozzle increase, and the flow of the nozzle suddenly shrinks. The resistance coefficient of the cross section to the downflush water is relatively large, and the energy loss of the pressure water is large when the nozzle flows out. When the flow pressure in the toilet is lower than 0.1Mpa, the pressure of the water cannot ...
