Detailed Description
The utility model will be described in detail with reference to the accompanying drawings and specific embodiments.
The present utility model provides a cover bidet having an anti-siphon structure, as shown in fig. 1 to 9, including a base plate 1 and a water inlet joint 2, an anti-siphon assembly 3, a water outlet valve assembly 7, and a washing assembly 11 provided on the base plate 1.
The anti-siphon assembly 3 comprises a shell 4 and an eccentric pad 6, wherein the shell 4 is provided with a water inlet 41, a water outlet 42, an air inlet 43 and an inner cavity 44 communicated with the water inlet, the water outlet and the air inlet. The water inlet 41 is communicated with the water inlet joint 2; the water outlet 42 is communicated with the water inlet end of the water outlet valve assembly 7, and the water outlet end of the water outlet valve assembly 7 is communicated with the water inlet end of the flushing assembly 11. In this embodiment, the housing 4 of the anti-siphon structure is connected to each component by a connector instead of a pipeline 12, as shown in fig. 7, a water inlet connector is formed at the water inlet 41 of the housing 4, and the water inlet connector is connected to the water inlet connector 2 by screw threads; a water outlet connector is formed at the water outlet 42 of the shell 4 and is connected with the water inlet end of the water outlet valve assembly 7. And sealing rings are further arranged at the joints to play a role in air sealing.
The present case is focused on that the eccentric pad 6 is rotatably provided in the inner cavity 44 of the housing 4 as shown in fig. 2 to 6, and the eccentric pad 6 is deflected up and down to close or open the air inlet 43. Specifically, as shown in fig. 8, the eccentric pad 6 is circular, one end of the eccentric pad 6 is pivoted to the side wall of the inner cavity 44 through the rotating shaft 61, and the other end is deflected up and down around the rotating shaft 61 to close or open the air inlet 43.
The principle of anti-siphon is as follows:
The water inlet joint 2 is connected with a water supply device, the water supply device supplies water, water flows into the inner cavity 44 of the shell 4 from the water inlet joint 2, under the action of water pressure, the eccentric pad 6 is pushed upwards to realize the sealing of the air inlet 43 (as shown in fig. 4), and then water flows out from the water outlet valve assembly 7. When the water inlet connector 2 loses water, the water inlet valve is still in an open state, at the moment, the inner cavity 44 of the shell 4 also loses water, the eccentric pad 6 loses water flow support and automatically falls under the action of gravity, the air inlet 43 is opened (as shown in fig. 5), so that the atmosphere enters the inner cavity 44 of the shell 4, and the pressure in the cavity is balanced, so that the residual water is prevented from flowing backwards, entering the water supply device and polluting the water supply source.
The eccentric pad 6 is provided with a sealing member 16 at the abutting part with the air inlet 43 of the shell 4 to improve the air tightness between the structures, and the sealing member 16 can be a soft rubber block or a rubber ring.
In this embodiment, as shown in fig. 8, the lower portion of the rotating shaft 61 extends radially downward to form a stopper 62, and when the eccentric pad 6 deflects downward, the stopper 62 can abut against the side wall of the inner cavity 44 of the housing 4, so that excessive deflection of the eccentric pad 6 can be prevented.
Since the stopper 62 is close to the water inlet 41 of the housing 4, there may be a situation of blocking the water inlet 41, so the inventor opens a water passing channel 63 communicating the water inlet 41 and the water outlet 42 of the housing 4 at the stopper 62 of the eccentric pad 6, that is, the stopper 62 is close to the water inlet 41, water can flow from the water passing channel 63 to the inner cavity 44 of the housing 4 without blocking the water inlet 41.
As shown in fig. 4 and 5, the side wall of the air inlet 43 is provided with an overflow opening 45, and the overflow opening 45 is connected with the flushing assembly 11 through an overflow pipe 5. When the inner cavity 44 of the shell 4 is filled with water, and the water flow rises to lift the eccentric pad 6, the splash can splash out of the air inlet 43 and flow to other positions of the body cleaner, and after the overflow port 45 is arranged, the splashed splash can flow to the flushing assembly 11 or other water outlet channels along the overflow pipe 5 from the overflow port 45, so that the problems are effectively solved.
As shown in fig. 7, the water outlet valve assembly 7 includes a valve body 8, a valve core 9, and a knob 10, the valve core 9 is located in the valve body 8, and the knob 10 is connected with the valve core 9 and is used for driving the valve core 9 to rotate relative to the valve body 8, so as to realize adjustment of the waterway. In the embodiment, a plurality of water inlet holes, a first water passing hole and a second water passing hole are formed in the valve core 9, a first water outlet nozzle 81 and a second water outlet nozzle 82 are formed in the valve body 8, and the first water passing hole is communicated with the first water outlet nozzle 81; the second water passing hole communicates with the second water outlet 82.
As shown in fig. 1, the water outlet end of the valve body 8 is connected with the water inlet end of the flushing assembly 11 through a pipe 12, the flushing assembly 11 comprises a first nozzle 111 and a second nozzle 112 which are arranged side by side, the first nozzle 111 is communicated with the first water outlet nozzle 81 through a first water pipe 121, and the second nozzle 112 is communicated with the second water outlet nozzle 82 through a second water pipe 122. The first nozzle 111 and the second nozzle 112 are both obliquely arranged on the bottom plate 1, so that the target object can be cleaned conveniently, and the cleaning force and the cleaning effect are improved.
The cover plate body cleaner also comprises an upper cover 13, as shown in fig. 2 and 9, wherein the upper cover 13 is buckled on the bottom plate 1, so that all components are hidden, and the functions of dust prevention and decoration are achieved.
Furthermore, as shown in fig. 2, the bottom of the base plate 1 is provided with two mounting members 14, the mounting members 14 being for mounting on a toilet seat. The type of the mounting member 14 may be bolt type, plug type, etc., and may be freely selected according to the needs of the customer and the type of the toilet, which is not limited in this case.
Fig. 9 shows a state in which the cover bidet of the present embodiment is mounted on the toilet seat 15.
