Description

Technical Field

[0001] The utility model generally relates to the technical field of bathroom equipment, and in particular to a water-resistant valve body. Background Art

[0002] In order to reduce the volume of the valve body, the existing valve body usually has water entering the water inlet directly rushing onto the rotating switching core and the valve stem. In this type of structure, the water flow directly impacts the valve plate and the valve stem, which will cause uneven force on the valve plate and the valve stem, resulting in water leakage when the valve plate is blocked and uneven rotational torque, which affects the service life of the valve body.

[0003] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field. Utility Model Content

[0004] The Summary of the Utility Model introduces a series of simplified concepts that will be further described in the Detailed Description of the Utility Model. This Summary of the Utility Model does not intend to limit the key features and essential technical features of the claimed technical solution, nor does it intend to determine the scope of protection of the claimed technical solution.

[0005] A main purpose of the present invention is to overcome at least one of the above-mentioned defects of the prior art and provide a valve body that is anti-water shock.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical solutions:

[0007] According to one aspect of the present invention, a water-surge-proof valve body is provided, comprising:

[0008] a housing, which is provided with a valve cavity, and a water inlet and a water outlet communicated with the valve cavity;

[0009] A valve core extends into the valve cavity and is used to block or open the water outlet; wherein,

[0010] A water blocking member is provided in the valve cavity for preventing water entering the water inlet from impacting the valve core.

[0011] According to one embodiment of the present utility model, the water retaining member includes a guide groove and a guide plate located below the guide groove, and the water entering the water inlet is guided along the guide groove.

[0012] According to one embodiment of the present invention, the guide groove and the guide plate are both extended along the circumference of the shell.

[0013] According to one embodiment of the present invention, at least one water hole is provided at the position where the guide groove and the guide plate are transitionally connected.

[0014] According to one embodiment of the present invention, the water retaining member is an annular enclosure structure, and the water retaining member and the shell are combined to form a switching cavity, or the water retaining member is a semi-annular enclosure structure.

[0015] According to one embodiment of the present invention, the housing includes a main body and a valve cover, the valve cover seal is detachably mounted on the upper portion of the main body, and the water retaining member is provided on the lower portion of the valve cover.

[0016] According to one embodiment of the present invention, the valve core includes a valve stem and a switching core, and the valve stem extends from the valve cover into the valve cavity and then cooperates with the switching core in transmission.

[0017] According to one embodiment of the present utility model, the switching core includes a movable valve plate movably arranged in the shell and a fixed valve plate fixed to the water outlet of the shell, and the valve stem is connected to the movable valve plate; there are at least two water outlets, and the movable valve plate and the fixed valve plate are relatively movable to switch the water outlet.

[0018] According to one embodiment of the present invention, the valve cover is provided with a sealing portion that is sealed with the main body, and the water retaining member is provided below the sealing portion and corresponds to the position of the water inlet.

[0019] From the above technical solution, it can be seen that the advantages and positive effects of the anti-slamming valve body of the utility model are:

[0020] 1. The anti-surge valve body of the utility model provides a water-blocking member on the path of water flowing from the water inlet to the valve core to hinder and block the water flow, so as to avoid the water in the water inlet directly impacting the valve core, thereby reducing the loss of the valve core and increasing the service life of the valve body.

[0021] 2. When the valve core adopts a cover-type valve disc structure, water entering the valve body's water inlet first impacts the water retaining member, then flows from top to bottom through the water retaining member's water flow hole into the switching chamber and toward the movable valve disc. At this time, the lateral impact of the water flow on the movable valve disc, valve stem and other structures is transformed into top-down pressure. Under this pressure, the movable valve disc and fixed valve disc are evenly stressed, and this pressure is consistent with the sealing force of the movable valve disc and fixed valve disc, which helps to improve the sealing effect of the movable valve disc and fixed valve disc, making it less likely to leak, extending the service life of the valve body, and improving the user experience.

[0022] 3. When the anti-slamming valve body of the utility model is a switching valve, a water retaining member with an annular guide groove is provided on the valve cover of the switching valve to isolate the water inlet from the movable valve plate, the fixed valve plate and the valve stem. When water enters, the water flow will not directly impact the valve plate or the valve stem, thereby protecting the switching structure to a certain extent. Without this structure, the water pressure will impact the valve plate and the valve stem, causing lateral pressure thereon. When the water inlet pressure is large enough, the water flow may cause the valve plate to tip over, and gaps and misalignments may appear between the movable valve plate and the fixed valve plate, causing the switching valve to fail to seal and leak, and may even cause the switching function to fail, affecting the product function.

[0037] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent like or similar structures, and thus their detailed description will be omitted.

[0038] The described features, structures or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present invention. However, those skilled in the art will appreciate that the technical solutions of the present invention can be practiced without one or more of the specific details, or other methods, components, materials, etc. may be employed. In other cases, well-known structures, materials or operations are not shown or described in detail to avoid obscuring various aspects of the present invention.

[0039] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0040] like Figures 1 and 2As shown, this embodiment provides a water-surge-proof valve body, comprising: a housing 100, which is provided with a valve chamber 101, and a water inlet 102 and a water outlet 103 connected to the valve chamber 101; a valve core, which extends into the valve chamber 101 and is used to block or open the water outlet 103; wherein, a water-blocking member 121 is provided in the valve chamber 101 for preventing water entering the water inlet 102 from impacting the valve core. It is understood that the number of water inlet 102 and water outlet 103 can be one each or multiple. The valve core can be of any shape, such as spherical, conical, pie-shaped, dome-shaped, cylindrical, etc. The water-blocking member 121 is provided on the path of water entering the water inlet 102 toward the valve core, obstructing and blocking the water flow. Its function is to prevent water entering the water inlet 102 from directly impacting the valve core by means of dispersion, consumption, and guidance, thereby reducing valve core wear. Therefore, the water-blocking member 121 can also be of any shape that can achieve this function.

[0041] In some embodiments, as Figures 3 to 5 As shown, the water retaining member 121 includes a guide groove 1212 and a guide plate 1213 located below the guide groove 1212. Water entering the water inlet 102 is guided along the guide groove 1212. It is understood that the guide groove 1212 plays a drainage role, guiding the water entering the water inlet 102 along the guide groove 1212 to the water hole 1211 to enter the switching chamber 111, thereby ensuring circulation efficiency, further reducing the water flow rate, and reducing the impact force.

[0042] In some embodiments, as Figures 3 to 5 As shown, the guide grooves 1212 and guide vanes 1213 are both arranged to extend circumferentially along the housing. It will be appreciated that the circumferential extension of the guide grooves 1212 and guide vanes 1213 can more effectively guide water entering the water inlet 102 to the side, reducing impact force while improving water diversion efficiency. In other embodiments, the guide grooves 1212 and guide vanes 1213 can also be arranged vertically, at an angle, or in other manners, and are not limited to circumferential extension.

[0043] In some embodiments, as Figures 3 to 5 As shown, at least one water hole 1211 is provided at the transition point between the guide groove 1212 and the guide plate 1213. In this embodiment, water entering the water inlet 102 first impacts the water retaining member 121, is then guided by the guide groove 1212, and flows through the water hole 1211 to the valve core, preventing the water flow from directly impacting the valve core. In this case, the guide groove 1212 is arranged around the outer periphery of the water retaining member 121, and multiple circumferentially arranged water holes 1211 can be connected in series, allowing water entering the water inlet 102 to flow into the switching chamber 111 from any position and angle.

[0044] In some embodiments, as Figures 3 to 5As shown, the water retaining member 121 is an annular enclosure structure, and the water retaining member 121 and the shell 100 are enclosed to form the switching chamber 111, or the water retaining member 121 is a semi-annular enclosure structure. It can be understood that the water retaining member 121 can be a ring that is a complete circle, a semi-circle, or a single arc segment. At this time, after the water entering the water inlet hits the water retaining member, it flows along the side of the water retaining member to the valve core in the valve chamber. In this embodiment, the water retaining member 121 is a ring that is a complete circle, and the annular enclosure structure of the water retaining member 121 can provide surrounding protection for the valve core on the inner side or lower side of the water retaining member 121, and the force is balanced, and the protection effect is better. The enclosure formation of the switching chamber 111 includes but is not limited to the water retaining member 121 that is a complete circle and the main body 110 of the shell 100, and can also include a valve cover 120. At the same time, the switching chamber 111 formed by the enclosure can be closed or semi-closed. The water entering the water inlet 102 first impacts the water retaining member 121 and then flows to the valve core. Figures 6 to 8 As shown, the water retaining member 121 is in the shape of a half circle or a single arc segment.

[0045] In some embodiments, as Figures 3 to 5 As shown, the housing 100 includes a main body 110 and a valve cover 120. The valve cover 120 is sealed and detachably mounted on the upper portion of the main body 110, and a water retaining member 121 is provided at the lower portion of the valve cover 120. In this embodiment, the housing 100 is a modular structure. The valve core and the water retaining member 121 can be installed and replaced by removing the valve cover 120, which facilitates manufacturing, assembly and maintenance.

[0046] In some embodiments, as Figures 3 to 5 As shown, the valve core includes a valve stem 300 and a switching core 200. The valve stem 300 extends from the valve cover 120 into the valve cavity 101 and then engages with the switching core 200. In this embodiment, the valve stem 300 extends from the valve cover 120 into the switching cavity 111. The portion of the valve stem 300 that passes through the water inlet 102 is protected by the valve cover 120 and the water stop 121, thereby avoiding direct impact from water entering the water inlet 102.

[0047] In some embodiments, as Figures 3 to 5As shown, the switching core 200 includes a movable valve disc 210 movably arranged in the housing 100 and a fixed valve disc 220 fixed to the water outlet 103 of the housing 100, and the valve stem 300 is connected to the movable valve disc 210; there are at least two water outlets 103, and the movable valve disc 210 and the fixed valve disc 220 are relatively movable to switch the water outlet. In this embodiment, the switching core 200 adopts a valve disc structure in which the movable valve disc 210 and the fixed valve disc 220 cover and seal each other. The movable valve disc 210 is rotated by the valve stem 300 to open the water outlet 103 on the fixed valve disc 220. The switching core 200 is arranged in the switching chamber 111, and the water retaining member 121 is arranged on the upper part of the switching core 200. The water entering the water inlet 102 first impacts the water retaining member 121, and then flows from the water hole 1211 of the water retaining member 121 into the switching chamber 111 from top to bottom and flows to the movable valve disc 210. At this time, the lateral impact of the water flow on the movable valve plate 210, valve stem 300 and other structures is converted into top-down pressure. Under this pressure, the movable valve plate 210 and the fixed valve plate 220 are evenly stressed, and this pressure is consistent with the sealing force of the movable valve plate 210 and the fixed valve plate 220, which helps to improve the sealing effect of the movable valve plate 210 and the fixed valve plate 220, making it less likely to leak, increasing the service life of the switching valve, and improving the user experience.

[0048] The valve body is a switching valve. A water retaining member 121 with an annular guide groove 1212 is provided on the switching valve cover 120 to isolate the water inlet 102 from the movable valve plate 210, the fixed valve plate 220, and the valve stem 300. When water enters, the water flow will not directly impact the valve plate or the valve stem 300, which protects the switching structure to a certain extent. If there is no such structure, the water pressure will impact the valve plate and the valve stem 300, causing lateral pressure thereon. When the water inlet pressure is large enough, the water flow may cause the valve plate to flip sideways, and gaps and misalignments will appear between the movable valve plate 210 and the fixed valve plate 220, causing the switching valve to fail to seal and leak, and may even cause the switching function to fail, affecting the product function.

[0049] In some embodiments, as Figures 3 to 5 As shown, the valve cover 120 is provided with a sealing portion 123 that seals with the main body 110, and the water retaining member is provided below the sealing portion 123 and corresponds to the position of the water inlet 102. It is understood that the sealing portion 123 can be a sealing structure including an O-ring 501.

[0050] For ease of understanding, this application also provides a more specific implementation:

[0051] like Figures 1 to 5As shown, this embodiment provides a water-surge-proof switching valve, comprising a housing 100, a switching core 200, and a valve stem 300. The housing 100 comprises a main body 110 and a valve cover 120. The valve cover 120 is removably and sealingly mounted on the upper portion of the main body 110. The valve stem 300 extends from the valve cover 120 into the valve cavity 101 within the housing 100, thereby engaging with the switching core 200 within the valve cavity 101. Specifically, the valve cover 120 is provided with a mounting flange 122 on its outer periphery, and the main body 110 is provided with a corresponding mounting hole 1101. The mounting flange 122 of the valve cover 120 is locked to the mounting hole 1101 of the main body 110 by screws 502. The valve cavity 101 is provided with a water inlet 102 and multiple water outlets 103, which are interconnected. O-rings are provided between the valve cover 120 and the housing 100, and between the valve stem 300 and the valve cover 120.

[0052] A water retaining member 121 is provided at the lower portion of the valve cover 120. The water retaining member 121 is an annular enclosure structure. The water retaining member 121 and the main body 110 of the shell 100 enclose a switching chamber 111. The water retaining member 121 includes a guide groove 1212 and a guide plate 1213 located below the guide groove 1212. At least one water hole 1211 is provided at the position where the guide groove 1212 and the guide plate 1213 are transitionally connected. The switching core 200 in the switching chamber 111 includes a movable valve plate 210 connected to the valve stem 300 and a fixed valve plate 220 fixed to the water outlet 103 of the shell 100. A spring 503 is provided between the valve stem 300 and the movable valve plate 210, and a sealing gasket 504 is provided between the fixed valve plate 220 and the water outlet 103. The valve stem 300 drives the movable valve plate 210 and the fixed valve plate 220 to move relative to each other to switch the water outlet.
