[0030] In order to make the technical problems, technical solutions and beneficial effects of the utility model to be solved clearer and more understandable, the utility model will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and not to limit the utility model.

[0031] Please refer to Figures 1 to 5 The utility model provides a kind of suction structure of electric bidet of preferred embodiment, including body 10, water pump 20 being located in body 10, spray head 30 being located in the front end of body 10 and connector 40 being located in the rear end of body 10. Connector 40 is used to be detachably connected with a water storage device (not shown, can directly use mineral spring bottle and other containers), connector 40 is equipped with a water inlet 41 and a suction port 42, after connector 40 is connected with the water storage device, water pump 20 can extract the water in the water storage device to spray head 30 to be sprayed to clean by water inlet 41, external air can enter the inner cavity of water storage device through suction port 42 to balance the internal and external pressure difference of water storage device. With the water outlet direction (such as Figure 2 The arrow shown in dashed line in the middle) as reference, define the water outlet direction of spray head 30 as upward direction, in the up-down direction of body 10, suction port 42 is located above water inlet 41 or flush with water inlet 41. Since the gas sucked by suction port 42 always moves upward, and water inlet 41 is located below suction port 42 or flush with suction port 42, therefore, air is not easy to be sucked into water inlet 41, so that the air amount entering water inlet 41 and then entering water pump 20 through pipeline can be effectively avoided or greatly reduced, and then the sprayed water flow is almost not affected by air, the water outlet is more smooth, water spray is stable and water outlet sound is normal. It can be understood that compared with the position of suction port 42 flush with water inlet 41, the effect of setting the position of suction port 42 above water inlet 41 is better.

[0032] The utility model defines the up-down direction of body 10 with the water outlet direction of spray head 30 as reference, refer to Figure 2 And Figure 3 The direction indicated in the middle.

[0033] The spray head 30 of the utility model can use existing known structure, and the specific structure of the spray head 30 is not limited, as long as it can receive the water output by the water pump 20 and spray water outward, so no detailed description is expanded.

[0034] In the embodiment, refer to Figure 2 The position of suction port 42 is set directly above water inlet 41. Of course, in other embodiments, the position of suction port 42 can also be selected to be set in the oblique upper side of water inlet 41, and the effect is equivalent.

[0035] In the embodiment, the air inlet 42 is provided with an air inlet check valve 50, which allows the ambient air to enter the water reservoir and prevents the water in the water reservoir from flowing out through the air inlet 42. In the preferred embodiment, the air inlet check valve 50 is a duckbill valve, which is simple in structure, easy to install and reliable in function. Of course, the air inlet check valve 50 is not limited thereto, and other known structures can also be used.

[0036] In the embodiment, the connector 40 includes a peripheral wall 43 and a partition wall 44 connected together, and the peripheral wall 43 and the partition wall 44 enclose a connecting cavity 45. The inner side of the peripheral wall 43 is provided with an internal thread, which is screwed with the external thread of the outlet of the water reservoir. It can be understood that the external thread can also be provided on the outer side of the peripheral wall 43, which is screwed with the internal thread of the outlet of the water reservoir. The detachable connection between the peripheral wall 43 of the connector 40 and the water reservoir is not limited thereto, and other connection modes such as clamping connection can also be used.

[0037] The water inlet 41 and the air inlet 42 are provided on the partition wall 44, and the air inlet end 51 of the air inlet check valve at least partially extends into the connecting cavity 45. The water inlet end 411 of the water inlet 41 is flush with one side of the partition wall 44 located in the connecting cavity 45, or the water inlet end 411 of the water inlet 41 protrudes from one side of the partition wall 44 located in the connecting cavity 45. The former is used in the embodiment. The water inlet end 411 of the water inlet 41 is closer to one side of the partition wall 44 located in the connecting cavity 45 than the air inlet end 51 of the air inlet check valve. In this way, the distance between the water inlet end 411 of the water inlet 41 and the air inlet end 51 of the air inlet check valve in the front-rear direction of the machine body 10 is pulled apart, which can further prevent the air sucked by the air inlet 42 from entering the water pump 20.

[0038] In the front-rear direction of the machine body 10, the distance L2 (see Figure 4 ) between the water inlet end 411 of the water inlet 41 and the air inlet end 51 of the air inlet check valve is preferably 0-20 mm, and more preferably 10-20 mm.

[0039] In the embodiment, a filter screen can be provided in the water inlet 41. The filter screen can prevent impurities in the water from being sucked into the water pump 20 and causing the water pump 20 to malfunction.

[0040] In the embodiment, the water inlet 41 and the air inlet 42 are spaced apart, and the distance between them is 10-20 mm. Spacing the water inlet 41 and the air inlet 42 apart can further effectively prevent or reduce the air sucked by the air inlet 42 from entering the water inlet 41. The distance L1 (see Figure 4 ) between the water inlet 41 and the air inlet 42 is preferably 10-20 mm, which is better.

[0041] In the embodiment, the distance L1 (see Figure 5The joint 40 is provided with a ventilation groove 46, one end of the ventilation groove 46 is communicated with the outside air, and the other end is communicated with the air inlet 42.

[0042] In the embodiment, referring to Figure 1 The electric bidet is further provided with a nozzle cover 31, the nozzle cover 31 is used for covering outside the nozzle 30, so as to protect the nozzle 30 and avoid that the nozzle 30 is polluted by the environment when being carried.

[0043] The utility model has been described above in connection with the drawings, obviously, the utility model concrete implementation is not limited by the above-mentioned mode, as long as various non-essential improvements of the method concept and technical scheme of the utility model are adopted, or the concept and technical scheme of the utility model are directly applied to other occasions without improvement, all are within the protection scope of the utility model.
