Description

Technical Field

[0001] This invention relates to the field of cleaning device technology, and more specifically, to a portable cleaner. Background Technology

[0002] Portable bidets, also known as portable bidets, portable body washers, or rinsing devices, are personal hygiene products designed to meet the needs of travel, special menstrual periods, or general hygiene. They act like a portable "personal cleaning assistant," allowing you to rinse with warm water anytime, anywhere, providing both hygiene and comfort. Bib washers come in manual and electric versions. Manual washers generate water pressure by manually pressing or squeezing the bottle; they are simple in structure, affordable, and require no charging, but the water pressure may be unstable and require two-handed operation. Electric washers, on the other hand, use a built-in battery to drive a water pump, providing stable water pressure, a comfortable water flow, and easy operation, often with one hand.

[0003] Chinese patent CN220876629U discloses a portable electric cleaning machine, including a housing. The housing is equipped with a water outlet pipe, a pump body, a water tank, a circuit board, and a power supply component. One end of the water outlet pipe is connected to a nozzle, and the other end is connected to the output end of the pump body. The power supply component and the pump body are electrically connected to the circuit board. The water tank is detachably fitted onto the outside of the housing, and one end of the housing is equipped with a connector. The water tank can be detached and assembled onto the connector. The connector is equipped with a water inlet and an air inlet. The input end of the pump body is connected to the water tank through the water inlet. The air inlet is equipped with a one-way valve to prevent water in the water tank from flowing out of the air inlet. By fitting the water tank onto the outside, it can be removed and reassembled when needed, which increases the water storage capacity of the water tank without affecting the internal installation, and its structural layout is more reasonable.

[0004] The above-mentioned prior art solution has a carrying state and a use state. In the carrying state, the part of the casing with the nozzle is inserted into the water tank, which reduces the volume of the machine when carrying and makes it easy to carry. In the use state, the casing is disassembled from the water tank, water is injected into the water tank, and then the connector of the casing is inserted into the water tank. The pump body draws water from the water tank through the water inlet and sprays it out from the nozzle for cleaning.

[0005] However, existing products have the following shortcomings: Firstly, in actual use, after the previous spraying operation, water remains in the internal pipes of the nozzle. When it is used again, after the connector is sealed and inserted into the water tank, the connector occupies a certain space inside the water tank, and the water tank is sealed and cannot be connected to the outside gas, which causes the gas pressure inside the water tank to increase. The instantaneous pressure generated inside the water tank will act on the inside of the casing, causing the water remaining inside the nozzle to overflow. Since the nozzle is usually used to clean the buttocks and private parts of the human body, the water overflowing from the nozzle makes the user feel that it is not hygienic, thus reducing the user experience. Secondly, the product requires the water tank to be inverted during use to facilitate water flow into the inlet and ensure complete water usage without waste. However, to balance the internal pressure of the water tank, a one-way valve is installed on the connector, allowing only air from inside the casing to enter the water tank. During use, as water enters the casing, air from inside the casing enters the water tank, producing a gurgling sound. Since this occurs while the user is washing their private parts, the extra noise from the product can cause embarrassment and negatively impact the user experience. Summary of the Invention

[0006] This invention overcomes the shortcomings of the prior art and proposes a portable cleaner with a reasonable structural design. By setting a pressure relief component, it can withstand the increased gas pressure in the water tank, preventing residual water in the nozzle from overflowing. Furthermore, gas can enter from the bottom of the water tank to balance the internal air pressure, without producing bubbling noise, thus improving the user experience.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A portable cleaner includes a housing and a water tank with a top opening. The housing has a water inlet and a water outlet positioned opposite each other, both of which can be inserted into the water tank. The water inlet is sealed to the water tank. A pump drive component is provided inside the housing. The water inlet has an inlet, and the water outlet has a nozzle. The pump drive component can draw water from the water tank through the inlet and discharge it through the nozzle. A pressure relief component is provided at the bottom of the water tank. The pressure relief component includes a mounting part, a valve body, and a diaphragm part. The mounting part is connected to the water tank. The valve body is a one-way valve structure that allows external gas to enter the water tank while preventing water from flowing out of the water tank. The diaphragm part can deform downward to withstand the increased gas pressure caused by the sealed insertion of the water inlet into the water tank.

[0008] By adopting the above technical solution, the pressure relief component can withstand the increased gas pressure in the water tank when the water inlet is sealed and inserted into the water tank, preventing residual water in the nozzle from overflowing; and when the water tank is used upside down, gas can enter from the bottom of the water tank to balance the internal air pressure, and no bubbling sound caused by gas entering the water will be generated, thus improving the user experience of the product.

[0009] Preferably, the mounting part is located on the outer periphery of the pressure relief member, the valve body part is located in the middle of the pressure relief member, the diaphragm part is located between the mounting part and the valve body part, the valve body part is set higher than the mounting part, and the diaphragm part extends from the mounting part to the valve body part in an arc shape or inclined shape from bottom to top.

[0010] By adopting the above technical solution, the pressure relief component is circumferentially fixed, the main body can be reset and deformed, and the middle part acts as a one-way valve. The overall structure and functional allocation are reasonable. The cross-section of the diaphragm part is arc-shaped or inclined, which can promote the diaphragm part to quickly bear pressure and elastically reset.

[0011] Preferably, the valve body includes a downwardly recessed receiving groove and a valve plate body disposed in the receiving groove and extending upward. The height of the valve plate body is less than or equal to the depth of the receiving groove. Two valve plates bodies are symmetrically arranged, and the two valve plates bodies are inclined and close together from bottom to top. The two valve plates bodies can be opened relative to each other to allow external gas to enter the water storage tank or closed to prevent water in the water storage tank from flowing out.

[0012] By adopting the above technical solution, the accommodating tank can store water. The water acts on the inclined sides of the two valve plates, causing the valve plates to close. When the water storage tank is inverted, there is no water in the accommodating tank, and the valve plates are not subjected to the force of the water. At this time, the external gas can act on the back of the valve plates, thereby causing the two valve plates to open and allowing the external gas to enter the water storage tank.

[0013] Preferably, the mounting section, diaphragm section, and valve body section are fixed or integrally connected.

[0014] By adopting the above technical solution, specifically, it can be an integral connection, using a uniform material, such as silicone, and the diaphragm part is set as a thin layer so that it can respond quickly to pressure and reset after the pressure is balanced.

[0015] Preferably, the bottom of the water storage tank is provided with an installation port, and the pressure relief component is sealed and assembled in the installation port.

[0016] By adopting the above technical solution, the installation port allows external gas to enter, while the pressure relief component seals the installation port to prevent water from leaking from the installation part.

[0017] Preferably, the water storage tank is provided with a connecting part at the installation port. The connecting part includes a horizontal beam and a vertical arm, and two positioning grooves are formed between the horizontal beam and the vertical arm. The installation part is provided with a vertical groove that matches the vertical arm, a horizontal groove that matches the horizontal beam, and a positioning strip that can be tightly fitted in the two positioning grooves.

[0018] By adopting the above technical solution, when installing the pressure relief component, the mounting part can be assembled to the connecting part from the mounting port and the top opening respectively. First, the vertical groove is assembled to the vertical arm. At this time, the crossbeam is also adapted to the horizontal groove. Then, the positioning strip is snapped into the positioning groove. Due to the properties of materials such as silicone, the mounting part can be allowed to undergo a certain deformation during assembly, and after the assembly and positioning are completed, a tight seal with the positioning groove is achieved.

[0019] Preferably, a support plate is provided below the installation port of the water storage tank. The support plate is provided with an air inlet. The support plate is separately fixed to the water storage tank. The support plate includes an inclined protrusion and a concave part. The inclined protrusion corresponds to the diaphragm part, and the concave part corresponds to the valve body part. The air inlet is provided on the concave part.

[0020] By adopting the above technical solution, the support plate can isolate and protect the pressure relief component from the outside. The support plate and the water storage tank are set separately. After the pressure relief component is assembled, it is fixed to the water storage tank. The setting of the inclined protrusion can reduce the distance between it and the diaphragm part. When the diaphragm part deforms downward, it can abut against the diaphragm part more quickly. The setting of the concave part does not block the concave part even when the diaphragm part abuts against the inclined protrusion part. External gas can also enter the water storage tank through the air inlet and the valve body part.

[0021] Preferably, a filter element and a filter plate are provided on the water inlet section above the water inlet. The filter element is located between the filter plate and the water inlet. The filter plate is fixedly installed on the water inlet section. A protective cover is provided on the outer cover of the water inlet section.

[0022] By adopting the above technical solution, the filter element can filter the water entering the housing, the filter plate allows water to enter and can press and position the filter element, and the protective cover plays a protective role when the water inlet is not inserted into the water storage tank.

[0023] Preferably, the pump body drive component includes a water pump and a battery, and a UV lamp and a light-transmitting sheet are provided inside the water inlet section.

[0024] By adopting the above technical solution, the pump body drive components include, but are not limited to, water pumps and batteries, as long as they can achieve water intake and pumping out. The ultraviolet light generated by the UV lamp passes through the light-transmitting sheet and can sterilize the water in the storage tank. Attached Figure Description

[0031] like Figure 1-10 As shown, a portable cleaner includes a housing 1 and a water tank 2 with a top opening 21. The housing 1 has a water inlet 3 and a water outlet 4 arranged opposite to each other. Both the water inlet 3 and the water outlet 4 can be inserted into the water tank 2. The water inlet 3 can be sealed with the water tank 2. A pump drive component is provided inside the housing 1. The water inlet 3 is provided with a water inlet 31, and the water outlet 4 is provided with a nozzle 41. The pump drive component can draw water from the water tank 2 through the water inlet 31 and discharge it through the nozzle 41. A pressure relief component 5 is provided at the bottom of the water tank 2. The pressure relief component 5 includes a mounting part 6, a valve body part 7, and a diaphragm part 8. The mounting part 6 is connected to the water tank 2. The valve body part 7 is a one-way valve structure that allows external gas to enter the water tank 2 while preventing water from flowing out of the water tank 2. The diaphragm part 8 can deform downward to withstand the increased gas pressure caused by the water inlet 3 being sealed and inserted into the water tank 2.

[0032] By adopting the above technical solution, the water inlet 3 and water outlet 4, which are arranged opposite to each other, can be inserted into the water tank 2 through the top opening 21, thus making it usable and portable. The water outlet 4 is also sealed with the water tank 2, allowing the user to add water to the water tank 2 in advance and then seal the water outlet 4 into the water tank 2, so that the water in the water tank 2 will not leak out when carried. The core solution of this application lies in the setting of the pressure relief component 5, which can bear the increased gas pressure in the water tank 2 when the water inlet 3 is sealed and inserted into the water tank 2, preventing the residual water in the nozzle 41 from overflowing; and when the water tank 2 is used upside down, gas can enter from the bottom of the water tank 2 to balance the internal air pressure of the water tank 2, and will not produce the sound of bubbles caused by gas entering the water, thus improving the user experience of the product.

[0033] The mounting part 6 is located on the outer periphery of the pressure relief member 5, the valve body part 7 is located in the middle of the pressure relief member 5, and the diaphragm part 8 is located between the mounting part 6 and the valve body part 7. The valve body part 7 is set higher than the mounting part 6. The diaphragm part 8 extends from the mounting part 6 to the valve body part 7 in an arc shape or inclined shape from bottom to top. The pressure relief member 5 is circumferentially fixed, the main body can be reset and deformed, and the middle part acts as a one-way valve. The overall structure and functional allocation are reasonable. The cross-section of the diaphragm part 8 is arc-shaped or inclined, which can enable the diaphragm part 8 to quickly bear pressure and elastically reset.

[0034] Furthermore, the valve body 7 includes a downwardly recessed receiving groove 71 and a valve plate 72 disposed in the receiving groove 71 and extending upward. The height of the valve plate 72 is less than or equal to the depth of the receiving groove 71. Two valve plates 72 are symmetrically arranged, and the two valve plates 72 are inclined and close together from bottom to top. The two valve plates 72 can be opened relative to each other to allow external gas to enter the water storage tank 2 or closed to prevent water in the water storage tank 2 from flowing out. The receiving groove 71 can store water. Water acts on the inclined sides 73 of the two valve plates 72, causing the two valve plates 72 to close. When the water storage tank 2 is inverted, there is no water in the receiving groove 71, and the valve plates 72 are not subjected to the force of water. At this time, external gas can act on the back of the valve plates 72, thereby causing the two valve plates 72 to open, allowing external gas to enter the water storage tank 2.

[0035] Furthermore, the mounting part 6, the diaphragm part 8, and the valve body part 7 are fixed or integrally connected. Specifically, they can be integrally connected and made of the same material, such as silicone. The diaphragm part 8 is made of a thin layer so that it can respond quickly to pressure and reset after the pressure is balanced.

[0036] In this embodiment, the bottom of the water storage tank 2 is provided with an installation port 22, and the pressure relief component 5 is sealed and assembled in the installation port 22. The installation port 22 allows external gas to enter, while the pressure relief component 5 acts as a seal for the installation port 22 to prevent water from leaking from the installation part 6.

[0037] Additionally, the water storage tank 2 is provided with a connecting part 23 at the mounting port 22. The connecting part 23 includes a crossbeam 24 and a vertical arm 25, forming two positioning grooves 26 between the crossbeam 24 and the vertical arm 25. The mounting part 6 is provided with a vertical groove 61 that matches the vertical arm 25, a horizontal groove 62 that matches the crossbeam 24, and a positioning strip 63 that can be tightly fitted in the two positioning grooves 26. When installing the pressure relief component 5, the mounting part 6 can be assembled to the connecting part 23 from the mounting port 22 and the top opening 21 respectively. First, the vertical groove 61 is assembled onto the vertical arm 25. At this time, the crossbeam 24 is also fitted and installed with the horizontal groove 62. Then, the positioning strip 63 is snapped into the positioning groove 26. Due to the properties of materials such as silicone, the mounting part 6 can undergo a certain deformation during assembly, and after assembly and positioning, it achieves a tight fit and seal with the positioning groove 26.

[0038] Furthermore, a support plate 9 is provided below the mounting port 22 in the water storage tank 2. The support plate 9 has an air inlet 91. The support plate 9 is separately fixed to the water storage tank 2. The support plate 9 includes an inclined protrusion 92 and a concave portion 93. The inclined protrusion 92 corresponds to the diaphragm portion 8, and the concave portion 93 corresponds to the valve body portion 7. The air inlet 91 is located on the concave portion 93. The support plate 9 can isolate and protect the pressure relief component 5 from the outside. The support plate 9 is separately fixed to the water storage tank 2 after the pressure relief component 5 is assembled. The inclined protrusion 92 can reduce the distance between it and the diaphragm portion 8, and can more quickly abut against the diaphragm portion 8 when it deforms downward. The concave portion 93 does not block the concave portion 93 even when the diaphragm portion 8 abuts against the inclined protrusion 92, and external gas can enter the water storage tank 2 through the air inlet 91 and the valve body portion 7.

[0039] As a further option, a filter element 32 and a filter disc 33 are provided on the water inlet section 3 above the water inlet 31. The filter element 32 is located between the filter disc 33 and the water inlet 31. The filter disc 33 is fixedly installed on the water inlet section 3, and a protective cover 34 is provided on the outside of the water inlet section 3. The filter element 32 can filter the water entering the housing 1, the filter disc 33 allows water to enter and can press and position the filter element 32, and the protective cover 34 provides protection when the water inlet section 3 is not inserted into the water storage tank 2.

[0040] The pump body drive component includes a water pump 11 and a battery 12. The water inlet 3 is equipped with a UV lamp 35 and a light-transmitting sheet 36. The pump body drive component includes, but is not limited to, the water pump 11 and the battery 12, as long as they can achieve water intake and pumping.
