Description

TECHNICAL FIELD

[0001] The utility model relates to a sanitary device technical field, especially is designed a kind of electric sanitary device. BACKGROUND

[0002] Sanitary device is a kind of device that can be used for local cleaning of human body, it usually includes host computer and water reservoir, host computer usually includes body and water pump, battery and circuit board etc.

[0003] In order to make in the process that water pump extracts water in water reservoir, outside air can enter water reservoir to balance the internal and external pressure difference of water reservoir, some existing sanitary devices are provided with air inlet, outside air can enter water reservoir through air inlet. In order to avoid water in water reservoir entering the inner cavity of body through air inlet in the normal state that water pump is not started, most of the existing sanitary devices adopt to set one-way valve at air inlet, by setting one-way valve, only allow outside air to enter water reservoir through air inlet, and do not allow water in water reservoir to flow out to the inner cavity of body through air inlet.

[0004] The air inlet and water inlet of the existing sanitary device communicated with water reservoir are separately set, two through openings are respectively opened on the joint connected with water reservoir, one through opening is used as water inlet for communicating water pump to extract water in water reservoir, and one through opening is used as air inlet for installing one-way valve to extract outside air into water reservoir. In order to make the structure of one-way valve simple, convenient to install and low in cost, some sanitary devices adopt common duckbill valve as one-way valve. However, the effect of preventing reverse flow of duckbill valve still needs to be improved. Duckbill valve is generally made of elastic material, and its shape is similar to duckbill, so it is called duckbill valve, and its working principle is that under the condition of no internal pressure, duckbill outlet is only closed under the elastic action of itself, and with the gradual increase of internal pressure, duckbill outlet gradually increases, so that fluid can flow out. However, under the condition of no internal pressure, duckbill outlet is only closed under the elastic action of itself, and for some materials with poor elasticity or aged elastic materials after a period of use, there are still some gaps even after closing, so that fluid flows out from the gaps, and the effect of preventing reverse flow is not reliable.

[0045] In order to make the technical problems, technical solutions and beneficial effects of the present application more clear, specific embodiments will be described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0046] Please refer to Figures 1 to 11 The present application provides a preferred embodiment of an electric bidet, which comprises a body 10, a water pump 20 arranged in the inner cavity of the body 10, a pipeline 60 arranged in the inner cavity of the body 10, a spray head 30 arranged at the upper end of the body 10, and a joint 40 arranged at the lower end of the body 10. The joint 40 is used to detachably connect with a water storage device (not shown, which can be a container such as a mineral water bottle). The water pump 20 can draw water from the water storage device through the pipeline 60 and spray the water out of the spray head 30.

[0047] The joint 40 is provided with a through opening 41, and a conical sleeve 50 made of elastic soft rubber is arranged at the through opening 41. The conical sleeve 50 has a small-diameter end 51 with a smaller diameter and a large-diameter end 52 with a larger diameter. The pipeline 60 comprises a water inlet pipe 61, and the water inlet pipe 61 is arranged in the conical sleeve 50. Referring to Figure 2 and Figure 3, in the normal state when the water pump 20 is not started, the small-diameter end 51 of the conical sleeve 50 elastically abuts on the outer wall of the water inlet pipe 61 to prevent the water in the water reservoir from flowing out through the through port 41, and the water flow from the through port 41 can further enter the inner cavity of the machine body 10 to damage the electronic elements (such as the battery 70 and the circuit board 90, etc. as described below) arranged in the inner cavity of the machine body 10; see Figure 4 and Figure 5 When the water pump 20 is pumping water, the water in the water reservoir can enter the water pump 20 through the water inlet pipe 61, and then be delivered to the spray head 30 for spraying, and in the process of pumping water by the water pump 20, the small-diameter end 51 elastically expands to form an air inlet gap C with the outer wall of the water inlet pipe 61 to allow external air to enter the water reservoir, see Figure 5 , Figure 5 The dashed line with an arrow in the figure indicates the flow path of the external air entering the water reservoir through the air inlet gap C.

[0048] In this embodiment, the large-diameter end 52 of the conical sleeve 50 is sleeved in the hole wall of the through port 41, and the outer diameter size of the large-diameter end 52 matches the inner diameter size of the through port 41, and the small-diameter end 51 of the conical sleeve 50 is located below the through port 41. The small-diameter end 51 of the conical sleeve 50 is located below the through port 41, so that the inner wall of the through port 41 does not block the outward deformation and expansion of the small-diameter end 51.

[0049] In this embodiment, the conical sleeve 50 includes upper and lower connected cylindrical segments 53 and a conical segment 54, the diameters of the cylindrical segments 53 are the same, the diameter of the conical segment 54 gradually decreases from top to bottom, the cylindrical segments 53 form the large-diameter end 52 of the conical sleeve 50, and the lower end of the conical segment 54 forms the small-diameter end 51 of the conical sleeve 50.

[0050] In order to facilitate the installation of the conical sleeve 50, in this embodiment, the conical sleeve 50 further includes an outward turning edge 55 connected to the upper end of the cylindrical segment, and the outward turning edge 55 abuts on the upper surface of the through port 41. Through the abutting limiting of the outward turning edge 55, the conical sleeve 50 cannot be pulled out of the through port 41.

[0051] In this embodiment, the connector 40 includes a peripheral wall 42 and a partition wall 43 connected to each other, and the peripheral wall 42 and the partition wall 43 surround a connecting cavity 44. The inner side of the peripheral wall 42 is provided with an internal thread, which is used for screwing with the external thread of the outlet of the water reservoir. It can be understood that an external thread can also be provided on the outer side of the peripheral wall 42 for screwing with the internal thread of the outlet of the water reservoir. The detachable connection mode of the peripheral wall 42 of the connector 40 with the water reservoir is not limited thereto, and the connector 40 can also be connected to the water reservoir in a clamping connection mode.

[0052] When the outlet of the water reservoir is connected to the peripheral wall 42, the connecting cavity 44 is in communication with the inner cavity of the water reservoir, and the through port 41 is arranged on the partition wall 43.

[0053] The upper portion of the connector 40 is connected to a base 80, and the base 80 and the partition wall 43 form a cavity 81 which is in communication with the outside air. The base 80 is provided with a through hole 82 through which the water inlet pipe 61 is sealed, and a plurality of limiting plates 83 are arranged at the periphery of the through hole 82. When the base 80 is connected to the connector 40, the limiting plates 83 abut against the upper surface of the outwardly flanged edge 55, so that the tapered sleeve 50 is fixed at the through opening 41. The structure is simple, and the installation is convenient by arranging the limiting plates 83 to fix the tapered sleeve 50 at the through opening 41. The base 80 and the connector 40 are fixedly connected by welding or clamping.

[0054] The water inlet end 6111 of the water inlet pipe and the small-diameter end 51 of the tapered sleeve 50 both extend into the connecting cavity 44, and the water inlet end 6111 of the water inlet pipe extends into the connecting cavity 44 by a distance greater than the small-diameter end 51 of the tapered sleeve 50. In this way, the water inlet end 611 of the water inlet pipe is separated from the small-diameter end 51 of the tapered sleeve 50 by a certain distance, so that the air entering the water reservoir from the small-diameter end 51 of the tapered sleeve 50 can be avoided or greatly reduced from being sucked into the water inlet end 611 of the water inlet pipe, thereby effectively reducing the influence of the air on the water flow.

[0055] Further preferably, in the embodiment, the distance L between the water inlet end 611 of the water inlet pipe and the small-diameter end 51 of the tapered sleeve 50 in the up-down direction of the machine body 10 is greater than or equal to 5 mm (see Figure 3 ), which is better for preventing the air entering the water reservoir from the small-diameter end 51 of the tapered sleeve 50 from being sucked into the water inlet end 611 of the water inlet pipe.

[0056] In the embodiment, referring to Figure 10 and Figure 11 , the water inlet connector 21 of the water pump 20 is directly used as the water inlet pipe 61, the pipeline 60 further includes a connecting pipe 62 and a water outlet pipe 63, the water outlet pipe 63 is connected to the spray head 30, and the connecting pipe 62 connects the water outlet connector 22 of the water pump 20 and the water outlet pipe 63. The water inlet connector 21 of the water pump 20 is directly used as the water inlet pipe 61 to pass through the through opening 41 to communicate with the water reservoir, so that the water pumping distance of the water pump 20 is very short, which greatly improves the pumping performance and the flushing effect is better. Of course, it can be understood that the water inlet connector 21 of the water pump 20 can not be directly used as the water inlet pipe 61 to pass through the through opening 41, but an additional water inlet pipe can be arranged at the front end of the water inlet connector 21 of the water pump 20. However, the water pumping distance is longer, which is not conducive to improving the pumping performance.

[0057] In the embodiment, the connector 40 is provided with an air vent groove 45, one end of the air vent groove 45 is in communication with the outside air, and the other end is in communication with the through opening 41. The outside air enters the water reservoir through the air vent groove 45 and the through opening 41.

[0058] In the embodiment, the water inlet pipe 61 is provided with a filter screen 612, and the filter screen 612 can prevent impurities in the water from being sucked into the water pump 20 to cause abnormal function of the water pump 20.

[0059] The spray head 30 of the utility model adopts the known structure, and the specific structure of the spray head 30 is not limited, as long as the spray head 30 can receive the water output by the water pump 20 and spray water outward, and therefore, the utility model will not be described in detail.

[0060] In the embodiment, referring to Fig. Figure 1 The body cleaner is also provided with a spray head cover 31, the spray head cover 31 is used for covering outside the spray head 30 to protect the spray head 30 and avoid the spray head 30 from being polluted by the environment when carrying.

[0061] In the embodiment, the body cleaner further comprises a battery 70 and a circuit board 90, the battery 70 and the water pump 20 are electrically connected with the circuit board 90 respectively, the battery 70 supplies power to the circuit board 90, and the circuit board 90 controls the opening and closing of the water pump 20.

[0062] The utility model discloses a taper sleeve 50 made of elastic soft glue is installed at the through port 41 of the joint 40, the water inlet pipe 61 is arranged in the taper sleeve 50, under the normal state that the water pump 20 is not started, the small diameter end 51 of the taper sleeve 50 elastically abuts on the outer wall of the water inlet pipe 61 to prevent the water in the water storage device from flowing out through the through port 41, and the water flow flowing out from the through port 41 can further enter the inner cavity of the machine body 10, that is to say, the water inlet pipe 61 passing through the taper sleeve 50 can make the small diameter end 51 of the taper sleeve 50 elastically deformed, thereby forming elastic pre-tightening force to make the small diameter end 51 reliably and elastically abut on the outer wall of the water inlet pipe 61 to realize reliable sealing, when the water pump 20 pumps water, the water in the water storage device can enter the water pump 20 through the water inlet pipe 61, and then be delivered to the spray head 30 to be sprayed out, and in the process that the water pump 20 pumps water, the small diameter end 51 elastically expands to form an air inlet gap C with the outer wall of the water inlet pipe 61 to allow the ambient air to enter the water storage device. Therefore, the utility model discloses that the water inlet pipe 61 is arranged in the taper sleeve 50 to make the small diameter end 51 of the taper sleeve 50 elastically and pre-tightly abut on the outer wall of the water inlet pipe 61 to realize reliable sealing to prevent the water in the water storage device from flowing out, and the utility model discloses a very ingenious idea and a very simple structure. Compared with the prior art, the duckbill valve is only folded under the elastic action of the duckbill valve itself, and the effect of preventing the water flow from flowing out of the through port is better.

[0063] In addition, compared with the prior art, the utility model discloses that only one through port 41 is arranged on the joint 40, the through port 41 is used for water and air, and therefore, the internal structure of the body cleaner is more integrated and compact.

[0064] The utility model has been described exemplarily above in combination with the drawings, obviously, the utility model specific implementation is not limited by the above-mentioned mode, as long as various non-essential improvements of method concept and technical scheme of adopting the utility model or the utility model concept and technical scheme are directly applied to other occasions without improvement, all are within the protection scope of the utility model.
