Abstract

The utility model discloses a pressure flushing device for the water closet, aiming at solving the problem that the prior art has a large water consumption and a poor flushing effect. The water box of the utility model comprises an inner cavity and an outer cavity; the button is connected with the inner sealing head in the inner cavity through the guide pole; the inner sealing head is sleeved with an outer sealing head; the inner sealing head is provided with an inner sealing ring; the though port between the inner cavity and the outer cavity is positioned under the top plate. The utility model can flush the water closet clean with small volume of water through adding pressure to the water; and the customer can preserve water and the water closet can be flushed immediately, therefore can reduce the smell in the washing room and the utility model has a good flushing effect.

Description

Flush toilet pressure flushometer

The utility model relates to a kind of flushometer, particularly a kind of pressure flushometer that is used for flush toilet.

Existing flush toilet uses water tank to accumulate water mostly, when the needs flush toilet, open the water valve that is positioned at water tank bottom, utilize the self gravitation flush toilet of water in the water tank, water cleans nightstool wall under the situation that does not have pressurization, for reaching the purpose of cleaning, need expend a large amount of water, cause the waste of water resource, user's use cost is also higher.The patent No. 92115089 discloses a kind of pressurized flush toilet system and device, contain water intaking valve, draining valve and water tank, after water enters the water tank of sealing from water intaking valve, the certain pressure of the compressed generation of air in the water tank, after opening draining valve, under the effect toilet is washed in the air pressure of water in the water tank in its gravity and water tank, the flushing system of this structure can clean up toilet with less water, thereby reach water-saving purpose, but its complex structure, volume is bigger, and its water tank can not retaining, and the user just can open water intaking valve in use, at water tank after water filling after a while, just can clean toilet, can leave more peculiar smell in the washroom, it is desirable that developing result is owed.

The purpose of this utility model is to provide the using water wisely of a kind of energy, the flush toilet pressure flushometer that developing result is good.

Flush toilet pressure flushometer described in the utility model, contain button, sealing radiator, water intaking valve, water tank contains inner chamber and exocoel, button is connected with interior end socket in the inner chamber by guide rod, interior end socket is with the covering head outward, on the interior end socket inner seal ring is housed, the cross section, position that outer end socket is corresponding with inner seal ring is tapered, the internal diameter of conical top is equal to or less than the external diameter of inner seal ring, outer end socket is equipped with outer seal ring on the position corresponding with water outlet of water tank, water outlet of water tank is back taper, its bottom internal diameter is equal to or less than the external diameter of outer seal ring, top board is equipped with at the top of outer end socket, and the external diameter of top board is equal to or less than the internal diameter of water tank cavity, and the openings between inner chamber and exocoel is positioned at below the top board.

Flush toilet pressure flushometer described in the utility model, air in the water filling rear water box is compressed and produces pressure, press the button in use, inner seal ring is thrown off outer end socket, water in the inner chamber flows out in outer end socket, the water surface descends in the inner chamber, consequent inner chamber, the top board of differential pressure action between exocoel on outer end socket, outer end socket is lifted, outer seal ring and water outlet of water tank break away from, pressurized water flows out used toilet is in time cleaned in the water tank, because use is the water of process pressurization, uses low amounts of water toilet can be cleaned up, but and user's preliminary infusion, use toilet in time to wash by water, the peculiar smell in the washroom can reduce, and developing result is good.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is a schematic diagram of the present utility model;

Embodiment 1

Flush toilet pressure flushometer described in the utility model, contain button 1, sealing radiator 2, water intaking valve, water tank 2 contains inner chamber 4 and exocoel 3, button 1 is connected with interior end socket 8 in the inner chamber 4 by guide rod, the interior end socket 8 outer covering heads 6 that are with, on the interior end socket 8 inner seal ring 9 is housed, the cross section, position that outer end socket 6 and inner seal ring 9 are corresponding is tapered, the internal diameter of conical top is equal to or less than the external diameter of inner seal ring 9, outer end socket 6 is equipped with outer seal ring 7 on the position corresponding with the delivery port of water tank 2, the delivery port of water tank 2 is back taper, its bottom internal diameter is equal to or less than the external diameter of outer seal ring 7, top board 5 is equipped with at the top of outer end socket 7, and the external diameter of top board 5 is equal to or less than the internal diameter of water tank cavity 4, and the openings that inner chamber 4 and exocoel are 3 is positioned at top board below 5; Air in the water filling rear water box is compressed and produces pressure, press the button 1 in use, inner seal ring 9 is thrown off outer end socket 6, water in the inner chamber 4 flows out in outer end socket 6, consequent inner chamber 4, the differential pressure action that exocoel is 3 is in top board 5, outer end socket 6 is lifted, outer seal ring 7 breaks away from the delivery port of water tank 2, pressurized water flows out used toilet is in time cleaned in the water tank 2, after water in the water tank 2 is emitted, outer end socket 6 is in the effect of the gravity original position that falls back, and inner seal ring 9 and outer seal ring 7 are sealed the water outlet position of inner chamber 4 and exocoel 3, water tank 2 water filling again; Be pressed with spring 10 at described top board 5 and 1 on button, button 1 is pressed the back and is resetted by spring 10; Spacing card 11 is housed on button 1, projection 12 is arranged on the correspondence position of water tank 2, the degree of depth of pressing with limit button 1, and can normally reset.

Embodiment 2

Described water intaking valve is a pressure valve, and when the pressure in the water tank was increased to a certain degree, pressure valve was closed, and after the water in the water tank was emitted, the pressure in the water tank reduced, and pressure valve is opened, to the water tank water filling.
