Description

Technical Field

[0001] This utility model relates to the field of feminine wash equipment. Background Technology

[0002] Existing feminine hygiene devices, such as the Chinese utility model patent CN204931536U entitled "A Portable Washer," disclose a portable washer comprising a water reservoir 1 and a washing device. The washing device consists of a shell 2, a top cover 3, a bottom shell 4, a support 5, a battery 6, an integrated circuit board 7, a dedicated USB interface hole 8, a protective pad 9, a motor 10, a water pump 11, a check valve 12, a drain pipe 13, a spring coil 14, an exhaust pipe 15, a charging terminal 16, a rigid plastic tube 17, an L-shaped connector 18, a nozzle 19, and screw posts 20. The top cover 3 is located at the upper end of the shell 2, and the lower end of the shell 2 is interlocked with the bottom shell 4. The support 5 is located inside the shell 2, and the battery 6 is located at the upper end of the support 5. The battery 6 is connected to the USB interface via the integrated circuit board 7. The motor 10 and the water pump 11 are mounted on the support 5, and the battery 6, integrated circuit board 7, and water pump 11 are connected in series via several wires. One end of the water inlet pipe 10 is connected to the water inlet hole of the top cover 3, and the other end is connected to the water pump 11. One end of the water pump 11 is connected to the drain pipe 13. One end of the exhaust pipe 15 is connected to the exhaust hole of the top cover 3, and the other end of the exhaust pipe 15 is connected to the rigid plastic pipe 17 on the same side as the exhaust pipe 15 on the other end of the bracket 5. The purpose of the exhaust pipe 15 in this portable cleaner is that when the water pump 11 draws water from the water storage cup 1, outside air can enter the water storage cup 1 through the exhaust pipe 15 and the exhaust hole of the top cover 3 to counteract the negative pressure formed in the water storage cup 1 due to water pumping.

[0003] The existing portable cleaners mentioned above require an exhaust pipe 15 to introduce outside air into the water storage cup 1 from the end away from the water storage cup 1. The exhaust pipe 15 runs almost axially through the entire outer shell 2. The exhaust pipe 15 is relatively long (i.e., the exhaust channel is relatively long), which not only increases the cost of the exhaust pipe 15, but also makes the internal structure of the portable cleaner more complex and the assembly more cumbersome. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a feminine douche and a feminine douche device that does not require a dedicated exhaust pipe, has lower cost, a simpler and more compact structure, and is easier and faster to assemble.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A bidet includes a housing, a micro pump, a battery, a water outlet, and a base. The water outlet and the base are respectively located at the top and bottom of the housing. The micro pump and the battery are located inside the housing. The battery powers the micro pump. The base is used to connect to an external water storage container. The micro pump is used to deliver water from the water storage container to the water outlet for spraying. During operation of the micro pump, outside air enters the water storage container through an air intake channel. The base is threadedly connected to the opening of the water storage container, and a first air passage gap is formed at the threaded connection. The first air passage gap forms part of the air intake channel.

[0007] In a preferred embodiment, one of the base and the water storage container is provided with an internal thread, and the other of the base and the water storage container is provided with an external thread. The bottom end of the internal thread is provided with an air passage groove to form the first air passage gap; or, the thread height of the external thread is less than the thread depth of the internal thread to form the first air passage gap; or, the thread width of the external thread is less than the thread width of the internal thread to form the first air passage gap.

[0008] In a preferred embodiment, the outer shell is provided with a water-proof plate, which axially divides the inner cavity of the outer shell into a mutually isolated receiving cavity and a connecting cavity. The micro pump and the battery are disposed in the receiving cavity, and the base is fixedly sleeved in the connecting cavity. The inner wall of the base is provided with an internal thread, which is used to connect with the external thread of the opening of the water storage container. The internal thread and the external thread form the first air passage gap. The water-proof plate is provided with a water inlet and an air inlet. When the water storage container is threadedly connected to the base, the water storage container is connected to the inlet of the micro pump through the water inlet, and the water storage container is connected to the air intake channel through the air inlet.

[0009] In a preferred embodiment, the base is an annular sleeve structure. An annular limiting ring is provided at the bottom end of the base away from the outer shell. The top surface of the annular limiting ring is sealed and fitted with the bottom surface of the water-proof sheet, and the bottom surface of the annular limiting ring is sealed and fitted with the end face of the opening of the water storage container. The annular limiting ring has a first through-channel penetrating its top and bottom surfaces, and the water-proof sheet has a second through-channel penetrating its top and bottom surfaces. The first air gap, the first through-channel, the second through-channel, and the water inlet are sequentially connected to form the air intake channel.

[0010] In a preferred embodiment, the accommodating cavity is further provided with a receiving component, on which the micro pump, the battery, and the circuit control board are mounted. The circuit control board is electrically connected to the micro pump and the battery. The bottom end of the receiving component is in contact with the water-proof sheet, and a second air gap is formed between the bottom end of the receiving component and the water-proof sheet. The first air gap, the first through channel, the second through channel, the second air gap, and the air inlet are sequentially connected to form the air intake channel.

[0011] In a preferred embodiment, the bottom end of the receiving component is connected to the water-proof sheet, and the receiving component and the water-proof sheet form an integrated structure of the micro pump, the battery and the circuit control board.

[0037] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0038] Please see Figures 1 to 10 This utility model provides a bidet 1, which includes a housing 10, a micro pump 20, a battery 30, a water outlet 40, and a base 50. The water outlet 40 and the base 50 are respectively located at the top and bottom of the housing 10, while the micro pump 20 and the battery 30 are located inside the housing 10. The battery 30 supplies power to the micro pump 20, and the base 50 is used to connect to an external water storage container 2. The micro pump 20 provides power to deliver water from the water storage container 2 to the water outlet 40 for use. During operation, outside air enters the water storage container 2 through an air intake channel 60 to counteract the negative pressure created by the pumping out of water. The base 50 is threadedly connected to the opening of the water storage container 2, and a first air passage gap 61 is formed at the threaded connection, which forms part of the air intake channel 60.

[0039] A first air gap 61 is provided at the threaded connection between the base 50 and the opening of the water storage container 2. This first air gap 61 forms part of the air intake channel 60. This design allows outside air to enter from the end closer to the water storage container 2, resulting in a shorter air intake channel 60. Furthermore, by incorporating the first air gap 61 at the threaded connection between the base and the opening of the water storage container 2 as part of the air intake channel 60, the structure is simple and compact, eliminating the need for a separate exhaust pipe 15 (i.e., air intake channel) as required by existing technologies. This reduces costs and simplifies assembly. Moreover, the placement of the first air gap 61 at the threaded connection ensures good concealment of the air intake structure; the air intake structure is not visible on the surface of the bidet 1, resulting in a cleaner appearance. In particular, the concealed air intake structure prevents accidental obstruction by the user during use, ensuring more reliable functionality.

[0040] One of the base 50 and the water storage container 2 is provided with an internal thread, and the other of the base 50 and the water storage container 2 is provided with an external thread. In specific implementation, the formation of the first air passage gap 61 can be carried out in the following ways: (1) designing an air passage groove 511 at the bottom of the thread of the internal thread to form the first air passage gap 61; (2) designing the thread height of the external thread to be less than the thread depth of the internal thread to form the first air passage gap 61; (3) designing the thread width of the external thread to be less than the thread width of the internal thread to form the first air passage gap 61. With this design, the structure for forming the first air passage gap is very simple. Specifically, in this embodiment, the inner wall of the base 50 is provided with an internal thread 51, the outer wall of the opening of the water storage container 2 is provided with an external thread 201, and the first air passage gap 61 is formed by the above-mentioned method (1), that is, by designing an air passage groove 511 at the bottom of the thread of the internal thread 51 of the base 50 to form the first air passage gap 61. Of course, it is understandable that the base 50 can also be provided with external threads and the water storage container 2 can be provided with internal threads. The formation of the first air gap 61 between the internal thread 51 and the external thread 201 is not limited to the three structures mentioned above, and will not be listed one by one here.

[0041] In this embodiment, a water-proof plate 70 is provided inside the outer shell 10. The water-proof plate 70 axially divides the inner cavity of the outer shell 10 into a mutually isolated receiving cavity 11 and a connecting cavity 12. That is, the water-proof plate 70 prevents the receiving cavity 11 and the connecting cavity 12 from communicating, and water in the connecting cavity 12 will not flow into the receiving cavity 11. The micro pump 20 and the battery 30 are disposed in the receiving cavity 11, and the base 50 is fixedly sleeved in the connecting cavity 12. The water-proof plate 70 is provided with a water inlet 71 and an air inlet 62. When the external thread of the opening of the water storage container 2 is threadedly connected to the internal thread 51 of the base 50, the water storage container 2 is connected to the inlet 21 of the micro pump through the water inlet 71, and the water storage container 2 is connected to the air intake channel 60 through the air inlet 62.

[0042] In this embodiment, the base 50 is an annular sleeve structure. An annular limiting ring 52 is provided at one end of the base 50 away from the bottom end of the outer shell 10. The top surface of the annular limiting ring 52 is sealed and fitted with the bottom surface of the water-proof sheet 70, and the bottom surface of the annular limiting ring 52 is sealed and fitted with the end face 202 of the opening of the water storage container 2. In this way, the water in the water storage container 2 will not flow out from between the top surface of the annular limiting ring 52 and the bottom surface of the water-proof sheet 70, and between the bottom surface of the annular limiting ring 52 and the end face 202 of the opening of the water storage container 2, thereby achieving a reliable seal on the opening 202 of the water storage container 2.

[0043] In this embodiment, the annular limiting ring 52 has a first through-channel 62 penetrating its top and bottom surfaces, and the water-blocking plate 70 has a second through-channel 63 penetrating its top and bottom surfaces. The first air gap 61, the first through-channel 62, the second through-channel 63, and the water inlet 71 are sequentially connected to form the air intake channel 60. This design of the air intake channel 60 results in a simple and compact structure. More specifically, in the air intake path of the air intake channel 60, a second air gap 64, as described below, is also provided between the second through-channel 63 and the water inlet 71. That is, the air intake channel 60 is composed of the first air gap 61, the first through-channel 62, the second through-channel 63, the second air gap 64, and the air inlet 62.

[0044] In this embodiment, the accommodating cavity 11 is further provided with a receiving component 80, on which a micro pump 20, a battery 30, and a circuit control board 90 are mounted. The circuit control board 90 is electrically connected to the micro pump 20 and the battery 30. The circuit control board 90 controls the opening and closing of the micro pump 20, as well as the power of the micro pump 20, etc. The battery 30 supplies power to the micro pump 20 through the circuit control board 90. The bottom end of the receiving component 80 is sealed and fitted to the top surface of the water-proof sheet 70. A second air gap 64, as described above, is formed between the bottom end of the receiving component 80 and the water-proof sheet 70. The first air gap 61, the first through channel 62, the second through channel 63, the second air gap 64, and the air inlet 62 are sequentially connected to form an air inlet channel 60.

[0045] In this embodiment, the bottom end of the housing 80 is connected to the water-proof plate 70. The housing 80 and the water-proof plate 70 form a single integrated structure of the micro pump 20, battery 30, and circuit control board 90, which makes assembly more convenient. During assembly, the micro pump 20, battery 30, and circuit control board 90 can be first installed into the cavity formed by the housing 80 and the water-proof plate 70. Then, the integrated structure consisting of the micro pump 20, battery 30, circuit control board 90, housing 80, and water-proof plate 70 can be installed into the inner cavity of the outer shell 10. The outer wall of the base 50 is sealed and fixed to the cavity wall of the connecting cavity 12 by welding. Of course, the two can also be sealed and fixed by adhesive bonding or by interference sealing with a sealing ring. When the outer wall of the base 50 is sealed and fixed to the inner wall of the outer shell 10, the base 50 limits the integrated structure within the receiving cavity 11 of the outer shell 10. The micro pump 20, circuit control board 90 and battery 30 are integrated into a single structure by means of housing 80 and water-proof plate 70. The high degree of integration makes the internal structure of the bidet 1 simpler and more compact, and the whole structure can be installed into the outer shell, which is convenient for assembly.

[0046] In this embodiment, the water-proof sheet 70 is made of a soft material, specifically silicone. The outer wall of the water-proof sheet 70 is sealed to the inner wall of the outer casing 10, the bottom surface of the water-proof sheet 70 is sealed to the top surface of the base 50 (i.e., the top surface of the annular limiting ring 52), and the top surface of the water-proof sheet 70 is sealed to the bottom end of the receiving component 80. Because the water-proof sheet 70 is made of a soft material, it can function as a soft rubber seal, eliminating the need for a separate soft rubber seal, thus simplifying the structure and saving on sealing costs.

[0047] Preferably, the housing 80 is also made of a soft material, so that the micro pump 20 is installed in the housing 80, which can cushion the micro pump 20, effectively reducing the vibration and noise of the micro pump 20 and improving the user experience. More preferably, the housing 80 is a cylindrical structure with a closed top and an open bottom. The outer wall of the top of the housing 80 is sealed to the inner wall of the outer shell 10. In this way, the top of the housing 80, the water-proof plate 70 and the inner wall of the outer shell 10 form a sealed cavity. The micro pump 20, the battery 30 and the circuit control board 90 are located in this sealed cavity, which will not cause malfunctions when exposed to water, and the function is more reliable.

[0048] In this embodiment, a duckbill valve 72 is integrally formed at the air inlet 62. That is, the duckbill valve 72 and the water-blocking plate 70 are integrally formed using silicone material. This eliminates the need to manufacture the duckbill valve 72 separately or assemble it separately, avoiding the hassle of manufacturing and assembling the duckbill valve 72. The function of the duckbill valve 72 is to allow outside air to enter the water storage container 2 in one direction, while preventing water in the water storage container 2 from flowing out through the duckbill valve 72.

[0049] In this embodiment, the micro pump 20 can be either a water pump or an air pump. Specifically, the micro pump 20 in this embodiment is a water pump, preferably a diaphragm water pump.

[0050] In this embodiment, in addition, refer to Figure 6 The present invention also provides a feminine wash device, including a feminine washer 1 and a water storage container 2, wherein the feminine washer 1 is any of the feminine washers described above.

[0051] The micro pump 20 and water outlet 40 of this invention can adopt existing known structures. The water outlet 40 only needs to be able to receive the water flow delivered by the micro pump 20 and spray it outward. The water storage container 2 can be a common water storage container in daily life, such as a mineral water bottle, which can improve the applicability of the bidet 1.

[0052] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
