Problems solved by technology

The top of the urinal of the toilet seat of the existing vacuum toilet is generally provided with several relatively independent flushing nozzles for flushing the cleaning surface of the urinal. Since the flushing nozzles are exposed, the dirt in the normal process of going to the toilet objects will splash on the flushing nozzles, and if the water spraying pressure is high, floating water will easily occur; if the water spraying pressure is turned down, the flushing water flow will be weak, which will easily cause the cleaning surface between the two flushing nozzles to exist. Flushing blind area, unable to flush in place
In addition, some vacuum toilets use annular outlet pipes instead of the above-mentioned several flushing nozzles, and use a plurality of water outlet holes distributed circumferentially at the bottom of the outlet pipe to flush the cleaning surface of the urinal. However, this method has the following disadvantages : The water outlet angle of the water outlet hole is limited, usually smaller than the water outlet angle of the flushing nozzle, so there is a flushing blind area between adjacent water outlet holes, and it cannot be flushed in place

Embodiment 1

[0043] See Figure 1-Figure 13 As shown, a vacuum toilet of the present invention includes a toilet seat 1 and a water spray unit 2, the toilet seat 1 is made of ceramic material, and the bottom of the toilet 11 of the toilet seat 1 is provided with a sewage outlet 111, the sewage outlet 111 Facing down or toward the rear side of the toilet seat 1 , the sewage outlet 111 is connected to the pipeline of the vacuum system. The top of the toilet bowl 11 of the toilet seat 1 is provided with a groove 112 extending along its circumferential direction, and the notch of the groove 112 faces downward; the water spray unit 2 is arranged in the groove 112, and the The water spray unit 2 includes a plurality of nozzles and a plurality of water pipes 22, the plurality of nozzles are distributed at intervals along the circumferential direction of the groove 112, and the adjacent nozzles are connected by the water pipes 22, at least one nozzle and / or Or at least one water pipe 22 is provid...

Embodiment 2

[0052] See Figure 14-Figure 19 As shown in the figure, a vacuum toilet of the present invention is different from the above-mentioned first embodiment in that the water spray unit 2 is annular, and the part of the water spray unit 2 located at the front end of the toilet 11 is a water pipe 22' The bottom end of the water pipe 22' is provided with a plurality of water outlet holes 221 spaced along its circumferential direction. In this way, the present invention can solve the problem that the front end of the toilet is arc or V-shaped, resulting in a small space and inconvenient to install the nozzle, and ensure the flushing effect of the front of the toilet 11 .

[0053] In this embodiment, the number of the nozzles is three, but not limited to this. The three nozzles include nozzles of two different shapes. The structure of the first type of nozzle 21 is the same or substantially the same as that of the first type of nozzle 21 in the above-mentioned first embodiment. The c...

Abstract

The vacuum closestool comprises a closestool seat and a water spraying unit, an annular or strip-shaped groove extending in the circumferential direction of a urinal is formed in the top of the urinal of the closestool seat, and an opening of the groove faces downwards; the water spraying unit is arranged in the groove, the water spraying unit comprises a plurality of nozzles and a plurality of water pipes, the nozzles are distributed at intervals in the circumferential direction of the groove, the adjacent nozzles are communicated through the water pipes, and at least one nozzle and/or at least one water pipe are/is provided with a water inlet. The water spraying unit can be shielded by the groove, and the problems that the water spraying unit is splashed by dirt and drifting is generated in the washing process are solved. Meanwhile, the flushing function of the nozzle is reserved, flushing blind areas can be reduced, and the flushing effect is improved.

Description

technical field [0001] The invention relates to a toilet, in particular to a vacuum toilet. Background technique [0002] The vacuum toilet uses a vacuum method to draw the dirt out of the toilet seat through the sewage pipe. Therefore, the water consumption of the vacuum toilet is generally in the range of 0.5 to 1L. Compared with the traditional flush toilet, the water consumption is greatly reduced. The top of the toilet seat of the existing vacuum toilet is generally provided with several relatively independent flushing nozzles for flushing the cleaning surface of the toilet. Objects will splash on the flushing nozzle, and if the water spray pressure is high, it is prone to drifting. The blind spot cannot be flushed in place. In addition, some vacuum toilets use annular water outlet pipes to replace the above-mentioned flushing nozzles, and use a plurality of water outlet holes distributed in the circumferential direction at the bottom of the water outlet pipes to flus...
