Abstract
Description
Technical Field
[0001] This application relates to the field of cleaning machine technology, and more specifically, to a waterproof two-way breathable cover and a cleaning machine. Background Technology
[0002] In the field of cleaning machines, it is necessary to use sealed containers to store liquids and use pumps to extract the liquids from the containers. When extracting liquids from the containers, it is necessary to keep the pressure inside and outside the containers consistent in order to ensure the normal operation of the cleaning machine equipment.
[0003] Currently, the cleaning machine industry typically uses a one-way breathable sealed container to store liquids. However, this method has a drawback: the expansion of gas inside the container cannot be released, causing a rapid increase in pressure and resulting in an imbalance between the internal and external pressures. Specifically: firstly, the inability to maintain pressure balance can lead to a decrease in pump power or malfunction; secondly, if the gas cannot be expelled in time, it can cause the container to expand and deform, and excessive pressure can even cause it to rupture, resulting in liquid leakage, equipment damage, and disruption of normal use. In severe cases, it can even threaten the safety of the user. While some cleaning machines now use two-way breathable sealed containers to store sweat liquids, achieving pressure imbalance and preventing leakage from container rupture, this method involves numerous plastic parts and seals, resulting in a complex structure that is less convenient to assemble and use.
[0004] Therefore, it is urgent for those skilled in the art to provide a waterproof two-way breathable cover with a simple structure that is suitable for storing liquid containers in cleaning machines. Using a waterproof two-way breathable cover can avoid the pressure imbalance between the inside and outside of the sealed container, prevent the liquid inside the container from leaking out of the container and prevent external moisture from entering and contaminating the liquid inside the container, thereby ensuring the two-way breathability, leak-proof and waterproof properties of the container containing the waterproof two-way breathable cover. Utility Model Content
[0005] The purpose of this application is to provide a waterproof, two-way breathable cover to solve the above-mentioned technical problems.
[0006] To achieve the above objectives, this application adopts the following technical solution:
[0007] This application provides a waterproof two-way breathable cover, comprising: a cover body having a first breathable hole and an inner surface of the cover body having an installation groove; a gasket installed in the installation groove, the gasket having a second breathable hole communicating with the first breathable hole; and a waterproof breathable membrane installed in the installation groove through the gasket, covering the first and second breathable holes, for blocking liquids and allowing gas to pass through; wherein, the installation groove has a sealing structure that is in close contact with the waterproof breathable membrane and the gasket.
[0008] In some of the technical solutions of this application, the sealing structure is a sealing rib.
[0009] Furthermore, the sealing rib includes a first sealing rib and a second sealing rib, both of which are annular. The first sealing rib corresponds to the end face of the gasket facing the inner side of the mounting groove and is in close contact with the waterproof and breathable membrane. The second sealing rib corresponds to the end face of the gasket facing the outer side of the mounting groove and is in close contact with that end face.
[0010] Furthermore, the first and second sealing ribs have triangular cross-sections. The triangular cross-section design of the sealing ring provides better pressure distribution because the triangular structure can more effectively disperse pressure, enhance sealing performance, and when subjected to pressure, its sharp apex can better cut into the sealing surface, thereby improving the sealing effect and preventing internal liquid leakage and external moisture inflow.
[0011] In some technical solutions of this application, the inner surface of the cover is provided with a boss, the mounting groove is provided in the boss, and the end face of the boss is provided with a mounting hole with a cross-section smaller than the mounting groove and communicating with the mounting groove. The mounting hole is used for embedding the waterproof and breathable membrane and the gasket into the mounting groove.
[0012] Furthermore, the inner wall of the mounting hole is provided with a mounting guide slope, which is used to guide the waterproof and breathable membrane and gasket to be embedded.
[0013] Furthermore, the diameter of the mounting hole facing the inner side of the mounting groove is smaller than the diameter of the outer side of the mounting groove, and the direction of the mounting guide ramp is a stepped structure with the diameter gradually decreasing from the outside to the inside. The design of the mounting guide ramp not only ensures that the waterproof and breathable membrane and gasket can slide smoothly into place and be accurately positioned along the mounting guide ramp during assembly, but also enhances the sealing performance, effectively avoids leakage problems caused by improper installation, and improves the airtightness and safety of the overall cover system.
[0014] In some technical solutions of this application, one side of the waterproof and breathable membrane is provided with an adhesive layer, and the waterproof and breathable membrane is connected to the gasket through the adhesive layer. The adhesive layer contains self-adhesive adhesive, which can adhere to the surface of the gasket under appropriate pressure. The function of the adhesive layer is to ensure that the waterproof and breathable membrane can be tightly fixed to the surface of the gasket.
[0015] Furthermore, the other side of the waterproof and breathable membrane is attached to the cover body and covers the first vent hole through the first sealing rib, and the gasket is attached to one end face of the receiving groove and covers the area around the mounting hole through the second sealing rib.
[0016] In some technical solutions of this application, the cover body includes a cover body and a cover sidewall. The cover body is circular and has a first vent hole at its center. The inner surface of the cover body has a boss. The cover sidewall is connected around the edge of the cover body.
[0017] Furthermore, the outer surface of the lid sidewall is provided with raised texture, and lugs are provided on the edge of the lid sidewall away from the lid body. The raised texture can achieve a sealing effect by increasing the contact area of the material and making it fit tightly with the sealed container, while improving the structural strength of the lid body and increasing the contact friction; the lugs can provide a larger operating area, making it more convenient to open or close the lid body.
[0018] This application also provides a cleaning machine, including a sealed container and the aforementioned waterproof two-way breathable cover, wherein the sealed container is provided with an installation port, and the waterproof two-way breathable cover is tightly installed on the installation port.
[0019] The waterproof two-way breathable cover of this application has a first breathable hole on the cover body and an installation groove on the inner surface. A waterproof breathable membrane connected to a gasket is placed in the installation groove. The gasket has a second breathable hole communicating with the first breathable hole. The waterproof breathable membrane covers the first and second breathable holes to block liquid while allowing gas to pass through. In addition, a sealing structure is provided in the installation groove to ensure tight contact between the waterproof breathable membrane and the gasket. The waterproof two-way breathable cover of this application is easy to produce, manufacture, and assemble. A sealed container with this waterproof two-way breathable cover can achieve two-way ventilation function between the inside and outside of the sealed container, maintain the air pressure balance between the inside and outside of the sealed container, and prevent the leakage of liquid inside the sealed container and the entry of external moisture, thus ensuring the stability of the liquid composition inside the container.

Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.
[0028] The current cleaning machine industry typically uses a one-way breathable sealed container to store liquids. While this allows outside gas to enter, the drawback is that the gas inside cannot escape, leading to a pressure imbalance between the inside and outside of the sealed container. Specifically, this pressure imbalance can cause a decrease in pump power or malfunction. Furthermore, if the gas cannot escape in time, it can cause the container to expand and deform, and excessive pressure can even cause it to rupture, resulting in liquid leakage, equipment damage, and even posing a safety threat to the user. Alternatively, the cleaning machine industry also uses a two-way breathable sealed container to store liquids. While this achieves pressure imbalance and prevents leakage from container rupture, this solution involves numerous plastic parts and seals, resulting in a complex structure that is less convenient to assemble and use.
[0029] The waterproof two-way breathable cover of this application has a simple structure and is suitable for use in liquid storage containers in cleaning machines. Using the waterproof two-way breathable cover can avoid the pressure imbalance between the inside and outside of the sealed container, prevent the liquid inside the container from leaking out of the container and prevent external water vapor from entering and contaminating the liquid inside the container, thereby ensuring the two-way breathability, leak-proof and waterproof properties of the container containing the waterproof two-way breathable cover, and improving the convenience and safety of use.
[0030] This application proposes a waterproof two-way breathable cover. The structure of the waterproof two-way breathable cover will be described in detail below with reference to the specific drawings.
[0031] like Figure 1 and Figure 2 As shown in the figure, this application provides a waterproof two-way breathable cover, including: a cover body 1 with a first breathable hole 111 and an inner surface of the cover body 1 with an installation groove 132. A gasket 2 is installed in the installation groove 132, and the gasket 2 has a second breathable hole 21 communicating with the first breathable hole 111. A waterproof and breathable membrane 3 is installed in the installation groove 132 through the gasket 2, covering the first breathable hole 111 and the second breathable hole 21, for blocking liquid and allowing gas to pass through. The installation groove 132 has a sealing structure that is in close contact with the waterproof and breathable membrane 3 and the gasket 2.
[0032] Regarding the structure of the cover 1, as an example, the cover 1 includes a cover body 11 and a cover sidewall 12, with the cover sidewall 12 surrounding the edge of the cover body 11. The cover body 11 is circular and has a first vent hole 111 at its center. The inner surface of the cover body 11 has a boss 13, and the boss 13 has a mounting groove 132. The outer surface of the cover sidewall 11 has raised textures 121, and the edge of the cover sidewall 12 away from the cover body 11 has lugs 122. The raised textures 121 can increase the contact area of the material to achieve an interference fit with the sealed container, thereby achieving a sealing effect, while also improving the structural strength of the cover 1 and increasing the contact friction. The lugs 122 can provide a larger operating area, making it easier to open or close the cover 1. The material of the cover 1 is rubber with a hardness of 60°, which achieves a sealing effect while also meeting the requirement of simple assembly. Rubber can effectively interfere with the sealed container to achieve a sealing effect.
[0033] Specifically, the end face of the boss 13 is provided with a mounting hole 131, the cross-section of which is smaller than that of the mounting groove 132 and communicates with the mounting groove 132. The diameter of the mounting hole 131 facing the inner side of the mounting groove 132 is smaller than that of the outer side of the mounting groove 132. The inner wall of the mounting hole 131 is provided with a mounting guide slope 1311. The mounting guide slope 1311 is used to guide the waterproof and breathable membrane 3 and the gasket 2 to be embedded into the mounting groove 132 through the mounting hole 131. The design of the mounting guide slope 1311 not only ensures that the waterproof and breathable membrane 3 and the gasket 2 can be smoothly embedded and accurately positioned along the mounting guide slope 1311 during the assembly process, but also enhances the sealing performance, effectively avoids leakage problems caused by improper installation, and improves airtightness and safety.
[0034] One side of the waterproof and breathable membrane 3 has an adhesive layer, which connects the membrane 3 to the gasket 2. The other side of the membrane 3 is attached to the cover body 11 and covers the first vent hole 111. The adhesive layer contains self-adhesive, which can adhere to the surface of the gasket 2 under appropriate pressure. The function of the adhesive layer is to ensure that the waterproof and breathable membrane 3 is tightly fixed to the surface of the gasket 2. The waterproof and breathable membrane 3 is a material with special functional properties, allowing gas to pass through while preventing moisture penetration. The membrane material of the waterproof and breathable membrane is usually composed of one or more porous polymer matrices, in which the pores are large enough to allow gas molecules to pass through, but small enough to prevent water vapor from passing through. The bidirectional waterproof and breathable cover containing the waterproof and breathable membrane of this application can meet the flow rate requirement of the pump body of not less than 500 ml / cm² / min when applied in a cleaning machine.
[0035] like Figure 3 and Figure 4 As shown, the sealing structure is a sealing rib 14. The sealing rib includes a first sealing rib 141 and a second sealing rib 142. The first sealing rib 141 is disposed between the cover body 11 and the waterproof and breathable membrane 3, and the second sealing rib 142 is disposed between the boss 13 and the gasket 2. The first sealing rib 141 corresponds to the end face of the gasket 2 facing the inner side of the mounting groove 132 and is in close contact with the waterproof and breathable membrane 3. The second sealing rib 142 corresponds to the end face of the gasket 2 facing the outer side of the mounting groove 132 and is in close contact with that end face.
[0036] Regarding the structure of the first sealing rib 141 and the second sealing rib 142, as an example, the cross-sections of the first sealing rib 141 and the second sealing rib 142 are triangular. The design of the sealing rib with a triangular cross-section can provide better pressure distribution because the triangular structure can more effectively disperse pressure, enhance sealing performance, and when the triangular sealing ring is under pressure, its sharp apex can better cut into the sealing surface, thereby improving the sealing effect and preventing internal liquid leakage and external moisture inflow.
[0037] The waterproof two-way breathable cover of this application can be used in high-pressure washers. It can be easily and tightly installed at the installation port of the sealed container holding the liquid in the washer. The cover side wall 12 of the cover body 1 can be interference-fitted with the outer edge of the installation port of the sealed container to achieve a sealing effect. When the liquid in the container is pumped out by a pump, the presence of the waterproof two-way breathable cover can keep the pressure inside and outside the container consistent to ensure the normal operation of the washer equipment. At the same time, it prevents the liquid inside the container from leaking out of the container and prevents external water vapor from entering and contaminating the liquid inside the container. This achieves two-way breathability, leak prevention and waterproofing of the washer.
[0038] The waterproof two-way breathable cover of this application has a boss 13 on the inner surface of the cover body 11, and a mounting groove 132 is provided in the boss 13. The mounting groove 132 is surrounded by the sidewalls of the boss 13. The two ends of the mounting groove 132 are the end of the boss 13 and the mounting hole 131 and the cover body 11 and the first vent hole 111, respectively. The mounting hole 131 is formed with a mounting guide slope 1311. The adhesive surface of the waterproof breathable membrane 3 is attached to the gasket 2 containing the second vent hole 21 and is tightly set in the mounting groove 132 through the mounting guide slope 1311. The first sealing rib 141 corresponds to the end face of the gasket 2 facing the inside of the mounting groove 132. It is in close contact with the waterproof and breathable membrane 3. The second sealing rib 142 corresponds to the end face of the gasket 2 facing the outside of the mounting groove 132 and is in close contact with the end face, so that the gas inside and outside the cover 1 needs to pass through the waterproof and breathable membrane 3 through the first vent hole 111, the second vent hole 21 and the mounting hole 131. The waterproof two-way breathable cover has a simple structure, is easy to produce, manufacture and assemble. The sealed container with the waterproof two-way breathable cover can realize the two-way breathability function inside and outside the sealed container, maintain the air pressure balance inside and outside the sealed container, and prevent the leakage of liquid inside the sealed container and the entry of external water vapor, thus ensuring the stability of the liquid composition inside the container.
[0039] The above description of the embodiments disclosed in this application enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
