The terminology used in the description of the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure.

Referring to fig. 1, fig. 1 is a perspective view illustrating a structure of a valve assembly 10 according to an embodiment of the present disclosure, and the present disclosure provides a valve assembly 10, where the valve assembly 10 can be applied to a water storage device 100 of a cleaning robot, for realizing unidirectional conduction and shutoff of water flow or air flow in a pipeline of the water storage device 100.

Referring to fig. 2 to 3 together, fig. 2 is a plan sectional view of the valve assembly 10 shown in fig. 1, and fig. 3 is an exploded view of the valve assembly 10 shown in fig. 1, the valve assembly 10 including a valve body 11, a valve body 12, and a support portion 13. The valve body 11 is provided with a fluid passage 1011, the fluid passage 1011 having an inlet end 10111 and an outlet end 10112 communicating with each other. The valve body 12 is provided in the fluid passage 1011, and the valve body 12 includes an elastic sealing portion 121, and the elastic sealing portion 121 is capable of being deformed reciprocally in the fluid flow direction. The supporting portion 13 is disposed in the fluid channel 1011, and the supporting portion 13 is disposed on a side of the elastic sealing portion 121 facing away from the inlet end 10111 and spaced apart from the elastic sealing portion 121 by a first predetermined distance.

When the elastic sealing part 121 is deformed to the first state, the elastic sealing part 121 is in interference fit with the supporting part 13, and the inlet end 10111 is communicated with the outlet end 10112, and when the elastic sealing part 121 is reset to the second state, the elastic sealing part 121 is arranged at intervals with the supporting part 13 and is in sealing fit with the inner wall of the fluid channel 1011, and the inlet end 10111 is blocked from the outlet end 10112.

As shown in fig. 2, under the action of no external force, the elastic sealing portion 121 is arranged at intervals with the supporting portion 13 and is in sealing fit with the inner wall of the fluid channel 1011, and the inlet end 10111 and the elastic sealing portion 121 are in a closed state, so that the inlet end 10111 and the outlet end 10112 are blocked. After the fluid enters the fluid passage 1011, the fluid flows from the inlet end 10111 toward the elastic sealing portion 121, and applies a force to the elastic sealing portion 121, so that the elastic sealing portion 121 deforms in a direction away from the inlet end 10111, and at the same time, an opening is formed between the inlet end 10111 and the elastic sealing portion 121, through which the inlet end 10111 and the outlet end 10112 communicate. Also, when the elastic sealing portion 121 is deformed in a direction away from the inlet end 10111 to be in interference engagement with the supporting portion 13, the opening degree of the opening is maximized, so that the degree of communication of the inlet end 10111 and the outlet end 10112 is maximized. Wherein the fluid may be a water stream, a gas stream, or a mixture of water and gas.

In the embodiment of the disclosure, the supporting portion 13 is disposed on one side of the elastic sealing portion 121 facing away from the inlet end 10111, and the supporting portion 13 and the elastic sealing portion 121 are disposed at a first preset interval, so when a fluid in the fluid channel 1011 enters the inlet end 10111, and forces the elastic sealing portion 121 to deform to a first state, so that when the inlet end 10111 communicates with the outlet end 10112, the elastic sealing portion 121 is in interference fit with the supporting portion 13, the supporting portion 13 can support the elastic sealing portion 121 and limit the deformation of the elastic sealing portion 121, and prevent the elastic sealing portion 121 from continuing to deform along the direction of fluid circulation, so that a certain opening is formed between the elastic sealing portion 121 and the inlet end 10111, the maximum opening between the elastic sealing portion 121 and the inlet end 10111 can be effectively limited, the fluid flow is prevented from being excessively large due to the excessive deformation of the elastic sealing portion 121, and the fluid flowing out of the outlet end 10112 can be kept at a certain flow rate when the elastic sealing portion 121 is deformed to the maximum.

The traditional mode adopts a mode of controlling the output power of the pump body to control the flow, and is limited by factors of poor stability of the output power and low control precision of the output power, so that the problems of easy overlarge condition and easy overflow of fluid in a pipeline are caused. According to the valve assembly disclosed by the embodiment of the disclosure, the maximum communication degree between the inlet end 10111 and the outlet end 10112 can be effectively and accurately controlled through the interval and the interference of the supporting part 13 on the elastic sealing part 121, so that the condition that the fluid in a pipeline is overlarge is effectively avoided, and the overflow and other problems are prevented.

It is to be understood that the first preset distance may be set according to practical needs, and only when the elastic sealing portion 121 is deformed to the first state, the flow rate of the fluid flowing from the inlet end 10111 to the outlet end 10112 is required.

Alternatively, the first preset distance is 1 to 2 mm, that is, the distance between the side of the elastic sealing portion 121 facing away from the inlet end 10111 and the side of the supporting portion 13 facing the elastic sealing portion 121 is 1 to 2 mm when the elastic sealing portion 121 is restored to the second state.

As shown in fig. 2 and 3, in some embodiments, the support portion 13 includes a plurality of first protrusions 131, and the plurality of first protrusions 131 are spaced around the circumference of the elastic sealing portion 121. Through the above arrangement, on one hand, when the elastic sealing portion 121 is deformed to the first state, one surface of the elastic sealing portion 121 facing away from the inlet end 10111 can be abutted against the plurality of first protrusions 131 along the circumference of the elastic sealing portion 121, the plurality of first protrusions 131 can uniformly support the elastic sealing portion 121 along the circumference of the elastic sealing portion 121, so that the deformation of the elastic sealing portion 121 in the circumferential direction is kept consistent, the distance between the elastic sealing portion 121 and the inlet end 10111 is kept consistent in the circumferential direction of the elastic sealing portion 121, thereby facilitating steady flow, on the other hand, by differentiating the supporting portion 13 into the plurality of first protrusions 131 arranged at intervals, a certain gap is formed between every two adjacent first protrusions 131, and when the elastic sealing portion 121 is supported, fluid can be allowed to pass through between the two adjacent first protrusions 131, thereby flowing to the outlet end 10112, the supporting portion 13 is prevented from being blocked, and the distance between every two adjacent first protrusions 131 can be kept consistent in the circumferential direction, so that the plurality of first protrusions 131 can also play a role in stabilizing fluid flowing to the outlet end 10112.

In some embodiments, the first protrusion 131 includes a connection arm 1311 extending along an axial direction of the fluid channel 1011 and a support arm 1312 extending along a radial direction of the fluid channel 1011, one end of the connection arm 1311 is connected to an inner wall of the fluid channel 1011, the other end of the connection arm 1311 is connected to the support arm 1312, and the support arm 1312 is located at a side of the elastic sealing portion 121 facing away from the inlet end 10111 and is spaced apart from the elastic sealing portion 121 by a first predetermined distance. With the above arrangement, the support arm 1312 can be lifted away from the inner wall of the fluid passage 1011 connected to the one end of the connection arm 1311 in the axial direction of the fluid passage 1011 so that there is a certain height between the support arm 1312 and the inner wall of the fluid passage 1011 connected to the one end of the connection arm 1311, and thus, when the elastic sealing portion 121 is in interference fit with the support arm 1312, there is a certain gap between the elastic sealing portion 121 and the inner wall of the fluid passage 1011 connected to the one end of the connection arm 1311 to allow fluid to flow therethrough.

As shown in fig. 4 and 5, fig. 4 is a plan sectional view of a valve assembly 10 provided in another embodiment of the present disclosure, and fig. 5 is an exploded view of the valve assembly 10 shown in fig. 4, in some embodiments, a support arm 1312 extends toward an outer side of an elastic sealing portion 121 along a radial direction of a fluid channel 1011 with respect to a connection arm 1311, and the support arm 1312 is provided with a support surface 13121 toward the elastic sealing portion 121, such that the support surface 13121 has a sufficient width in the radial direction of the fluid channel 1011, and when the elastic sealing portion 121 is deformed to a first state, the elastic sealing portion 121 can be engaged with the support surface 13121 in the radial direction, so that each portion of the elastic sealing portion 121 is uniformly deformed to contribute to stabilizing a flow rate, and the support surface 13121 can better support the elastic sealing portion 121 and better limit deformation of the elastic sealing portion 121. Moreover, the axially extending connecting arms 1311 may be provided relatively thin to enable fluid flow from the gap between adjacent two connecting arms 1311.

In some embodiments, the supporting surface 13121 extends away from the elastic connection portion gradually along the extending direction of the supporting arm 1312 to form an arc surface, so that when the elastic sealing portion 121 is in interference fit with the supporting surface 13121, the cross section of the elastic sealing portion 121 can form an arc shape along with the supporting surface 13121, and at this time, along the radial direction of the elastic sealing portion 121, the size of the opening between the elastic sealing portion 121 and the inlet end 10111 is gradually increased, and when the outline shape of the elastic sealing portion 121 is umbrella-shaped, the opening can be adapted to the outline shape.

With continued reference to fig. 2 and 3, in some embodiments, the valve core 12 further includes a connecting portion 122, the connecting portion 122 is connected to the elastic sealing portion 121 and disposed away from the inlet end 10111, the valve assembly 10 further includes a fitting portion 14, the fitting portion 14 is disposed in the fluid channel 1011 and connected to an inner wall of the fluid channel 1011, the fitting portion 14 is connected to the connecting portion 122 such that the elastic sealing portion 121 is spaced from the supporting portion 13 by the above-mentioned first predetermined distance, so that the elastic sealing portion 121 can be kept at the same position without external force, so that the elastic sealing portion 121 can be always in sealing engagement with the inner wall of the fluid channel 1011 without external force, so that the inlet end 10111 is blocked from the outlet end 10112, and the connecting portion 122 is located at a position where the elastic sealing portion 121 is away from the inlet end 10111, so as to avoid that the inlet end 10111 and the connecting portion 122 need to be staggered from each other on the same side of the elastic sealing portion 121 to affect the fluid outflow of the inlet end 10111.

Optionally, the axes of the inlet end 10111, the elastic sealing portion 121, the connecting portion 122, and the outlet end 10112 coincide, so that the size of the opening formed is uniform, contributing to the stability of the flow rate.

In some embodiments, the fitting portion 14 includes a plurality of second protrusions 141, the plurality of second protrusions 141 being spaced apart along the outer circumference of the connection portion 122 and cooperatively forming a fitting groove 1401 for fitting the connection portion 122, the plurality of second protrusions 141 being located inside the plurality of first protrusions 131. Through the arrangement, on one hand, the connecting part 122 can be limited by arranging the assembling groove 1401 on the assembling part 14, during installation, only the connecting part 122 of the valve core 12 is required to be in plug-in fit with the assembling groove 1401, during disassembly, only the connecting part 122 of the valve core 12 is required to be pulled out of the assembling groove 1401, the valve core 12 can be conveniently installed in the fluid channel 1011 or detached from the fluid channel 1011, on the other hand, by differentiating the assembling part 14 into a plurality of second bulges 141 which are arranged at intervals, a certain gap is reserved between every two adjacent second bulges 141, and when the limit of the connecting part 122 is realized, fluid can be allowed to pass through between the two adjacent second bulges 141, so that the flow to the outlet end 10112 is avoided, the blocking of the assembling part 14 is avoided, the distance between every two adjacent second bulges 141 is the same, and the second bulges 141 can play a certain uniform flow effect on the fluid flowing to the outlet end 10112.

In some embodiments, the second protrusion 141 is provided with a first surface 1411 and a second surface 1412 spaced apart along the direction of the fluid channel 1011. The first surface 1411 is attached to the outer side wall of the connecting portion 122 to axially limit the connecting portion 122, so that the valve core 12 can be fixed at the same position in the axial direction, when no external force acts on the valve core, the first surface 1411 can enable the elastic sealing portion 121 to abut against the inlet end 10111 and be in sealing fit with the inner wall of the circulation channel through abutting against the connecting portion 122, and when the fluid presses the elastic sealing portion 121, the first surface 1411 can support the whole valve core 12 through the connecting portion 122. The second surface 1412 and the elastic sealing portion 121 are disposed at a second preset interval, and the second surface 1412 is disposed near the elastic sealing portion 121 relative to the first surface 1411, so that the deformation of the elastic sealing portion 121 caused by the direct collision of the second protrusion 141 with the elastic sealing portion 121 when the elastic sealing portion 121 is restored to the second state can be avoided. And, the second preset interval is smaller than or equal to the first preset interval, so that the elastic sealing portion 121 in the first state can be abutted by the second surface 1412, so that the deformation of the elastic sealing portion 121 is more uniform, and uniform openings can be formed to stabilize the flow. When the second preset distance is smaller than the first preset distance, the second preset distance can be matched with the elastic sealing portion 121 with the umbrella-shaped outline, so that the deformation amplitude of the elastic sealing portion 121 is adapted to the outline of the elastic sealing portion, and uniform openings can be formed. Wherein the first surface 1411 is located in the fitting groove 1401 and the second surface 1412 is located at an end face of the second protrusion 141 near the elastic sealing portion 121.

In some embodiments, when the elastic sealing portion 121 is deformed to the first state, the elastic sealing portion 121 is in interference fit with both the supporting portion 13 and the second surface 1412, and the inlet end 10111 is communicated with the outlet end 10112, so that, while the peripheral portion of the elastic sealing portion 121 is in interference fit with the first protrusion 131, the inner peripheral portion of the elastic sealing portion 121 can be in interference fit with the second surface 1412, so that further support is obtained from the second protrusion 141, a gap between the connecting portion 122 and the first protrusion 131 is avoided when the elastic sealing portion 121 is deformed to the first state, and excessive deformation of the elastic sealing portion 121 is prevented, so that the deformation of the elastic sealing portion 121 is more uniform, and a uniform opening is facilitated to form to stabilize the flow. When the elastic sealing portion 121 is restored to the second state, the elastic sealing portion 121, the supporting portion 13 and the second surface 1412 are disposed at intervals and are in sealing engagement with the inner wall of the flow channel, and the inlet end 10111 and the outlet end 10112 are blocked.
