Abstract

The utility model provides a water-saving squatting pan consuming a very small quantity of water. Based on the profile structure of a traditional squatting pan, the porous uniform-distribution structure at the periphery of the inner side of the squatting pan main body is changed into a one-way spray hole structure; one-way spray holes are always arranged at one end of a dirt stagnation slope of the inner side of the squatting pan; the spraying direction of a high-speed spraying water flow is always aligned with the dirt stagnation slope; and the number N of the one-way spray holes is smaller than or equal to 5. When a switch of a water valve is switched on, by the combined action of the fluid continuity principle and the water pressure, tap water sprayed from the one-way spray holes at a high speed has huge momentum and impact force; and dirt piled at an end of the slope of the squatting pan can be flushed away from the original place, can drop in a sewage drain outlet, and can be drained away by only a very small quantity of tap water.

Description

Water-saving squatting pan

One, technical field

The utility model relates to the sanitary apparatus that often uses in a kind of people's daily life, especially a kind of water-saving squatting pan.

Two, background technology

The various pans of selling on the market are the traditional product of feature with the gravity flush still at present, and its design concept is that hypothesis is not having under the prerequisite of tap water, need only rely on 2 meters～3 meters the gravity flow that height fall produced to wash dirt.Since generally less through the impulse force of 2 meters～3 meters flushing current that height fall produced, need to strengthen the quantity that sluices down, so traditional pan generally can be designed to the porous water-spraying flushing mechanism when design.Though tap water moves towards huge numbers of families rapidly along with the continuous development of urbanization, because porous water-spraying flushing pan does not influence, repels tap water, so pan has just never had great essential improvement since invention.

Fig. 1, Fig. 2 is traditional pan structure of generally using at present, the closet inner peripheral the bath hole more, quantity is usually all more than 30, directly cause the Guang sectional area summation number of hole for water spraying to decuple to open or close the Guang sectional area of limbers in the switch of tap water, the hydraulic pressure that has disperseed former tap water pipe network, this basic principle that is inversely proportional to according to flow velocity and sectional area as can be known, though this moment, the number of share of stock and the flow of jet water course were many, but the impact force that its sub-thread or back, interflow are produced is very little, in most cases all be unfavorable for towards the blowdown thing, so traditional pan of all uses, generally need to wash the above tap water of 6L～8L, very waste, the utmost point is unfavorable for using water wisely.

Three, utility model content

The general water supply volume of traditional pan is big in order to overcome, the unfavorable critical defect of dirt removal effect, and the utility model provides a kind of water-saving squatting pan, and this water-saving squatting pan not only water supply volume is few, and the dirt removal works very well.

The technical scheme that its technical problem that solves the utility model adopts is: the inner peripheral porous distribution equalizing structure of traditional pan is changed over unidirectional jet orifice structure, it is characterized in that: A, unidirectional spray orifice are located at the inboard dirt of closet all the time and stagnate a domatic end, and the injection direction of high-speed water jets is aimed at dirt all the time and stagnated domatic; The quantity N of B, unidirectional spray orifice≤5; C, unidirectional spray orifice are symmetrical in the longitudinal central axis line setting of water-saving squatting pan main body all the time; The cross-sectional area sum total S＜3cm of D, unidirectional spray orifice ²After people opened tap water, tap water can only spray at a high speed from unidirectional spray orifice, and acted on dirt all the time and stagnate domatic and dirt is stagnated and piled up the cross section.Because the acting in conjunction of fluid continuity principle and hydraulic pressure, have great momentum and impact force from the tap water of unidirectional spray orifice high speed ejection, so the dirt that only needs few tap water can will pile up at the domatic end of pan dashes from the original place, is drained until falling into sewage draining exit.

The utility model has the advantages that: the dirt stagnation is domatic piles up the cross section with dirt because the injection direction of high-speed water jets and refractive direction are aimed at the form of comparatively concentrating all the time, high-speed water jets can form bigger impact force in the scope of concentrating relatively, so not only dirt removal is effective, and water supply volume is few, only needs 1L～2L tap water to get final product usually.

Fig. 3 is the sectional structural map of first embodiment of water-saving squatting pan.

Fig. 4 is that the A-A of Fig. 3 is to sectional view.

Fig. 5 is the sectional structural map of second embodiment of water-saving squatting pan.

Five, the specific embodiment

In Fig. 4 and embodiment shown in Figure 6, though water inlet pipe mouth (9) the position is set and direction has nothing in common with each other, all the inboard that only dirt is piled up end in toilet body (7) is provided with unidirectional spray orifice (10).

Can find out obviously that unidirectional spray orifice is located at the inboard dirt of closet all the time and stagnates a domatic end from Fig. 3, Fig. 4 and Fig. 5, embodiment shown in Figure 6, the injection direction of high-speed water jets is aimed at dirt all the time and is stagnated domatic; The quantity N of unidirectional spray orifice≤5; Unidirectional spray orifice is symmetrical in the longitudinal central axis line setting of water-saving squatting pan main body all the time; The cross-sectional area sum total S＜3cm of unidirectional spray orifice ²Water-saving squatting pan in use, after people open the water valve gauge tap, water inlet pipe mouth (9) has the hydraulic pressure identical with the tap water pipe network with the interior horse back of tap water passage (14), because the cross-sectional area of unidirectional spray orifice (10) is less, the pressure potential loss of tap water (8) is less, under the effect of fluid continuity principle, tap water (8) can only with high jet velocity and greatly impact force rush at dirt and stagnate domatic and dirt is piled up the cross section, so only need the tap water (8) of few quantity dirt can be rushed in waste collection port (12) and drain during each the use, and the dirt after the flushing is stagnated domatic very clean.

Claims

1. water-saving squatting pan, be on traditional pan contour structures basis, the porous distribution equalizing structure of toilet body inner peripheral is changed over unidirectional jet orifice structure, it is characterized in that: A, unidirectional spray orifice are located at the inboard dirt of closet all the time and stagnate a domatic end, and the injection direction of high-speed water jets is aimed at dirt all the time and stagnated the quantity N of domatic B, unidirectional spray orifice≤5.
