[0017] According to some embodiments of the present invention, the cross-sectional dimension of the connecting hole is larger than the cross-sectional dimension of the top rod portion;

[0018] Alternatively, the connecting hole includes a plug hole and a flow channel hole, and the push rod portion is used to penetrate the plug hole to act on the valve core.

[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0047] See also Figures 1 to 3, a water pressure detection device provided by an embodiment of the present invention, includes a water pressure sensor 100 and an on-off valve body 200, wherein the water pressure sensor 100 is provided with a plug-in portion 111 and a push rod portion 112, and the on-off valve body 200 includes a valve seat 210, a valve core 220 and an elastic member 230, wherein the valve seat 210 is provided with a fluid channel 211, and the valve core 220 is movably connected to the fluid channel 211 so as to be able to switch between a first position and a second position to close or open the fluid channel 211, and the elastic member 230 is connected to the valve seat 210 and the valve core 220, and is used to enable the valve core 220 to be able to switch between a first position and a second position to close or open the fluid channel 211, and the elastic member 230 is connected to the valve seat 210 and the valve core 220, and is used to enable the valve core 220 to switch from the second position Reset to the first position; when the valve core 220 is in the first position, the fluid channel 211 is in a closed state, that is, the fluid channel 211 is closed by the valve core 220, and when the valve core 220 is in the second position, the fluid channel 211 is in an open state, that is, the fluid channel 211 is not closed by the valve core 220; wherein, when the plug-in portion 111 is plugged into and snap-connected with the valve seat 210, the valve core 220 is suitable for the force of the push rod portion 112 to switch from the first position to the second position; and, when the plug-in portion 111 is separated from the valve seat 210, the valve core 220 is suitable for the elastic reset force of the elastic member 230 to switch from the second position to the first position.

[0048] Among them, the valve core 220 is movably connected to the fluid channel 211. For example, the valve core 220 is rotatably set on the valve seat 210, and the push rod portion 112 is used to push the valve core 220 to rotate so as to achieve the switching of the valve core 220 between the first position and the second position; or, the valve core 220 is slidably set on the valve seat 210, and the push rod portion 112 is used to push the valve core 220 to slide so as to achieve the switching of the valve core 220 between the first position and the second position.

[0049] Specifically, when the water pressure detection device is in use, the plug-in portion 111 is plugged and connected to the valve seat 210, and the push rod portion 112 overcomes the elastic force of the elastic member 230, pushes the valve core 220 to remain in the second position, and the fluid channel 211 of the valve seat 210 is in an open state. Therefore, the liquid cooling delivery system flows the liquid cooling water from the fluid channel 211 into the water pressure sensor 100, and the water pressure sensor 100 detects the water pressure of the liquid cooling delivery system. If the water pressure sensor 100 needs to be repaired or replaced, since the plug-in portion 111 is plugged and snap-connected to the valve seat 210, the staff can easily separate the plug-in portion 111 from the valve seat 210, thereby quickly disassembling the water pressure sensor 100 from the on-off valve body 200 to repair or replace the water pressure sensor 100; wherein, during the disassembly process of the water pressure sensor 100, the push rod portion 112 releases the restriction on the valve core 220, at which time, the valve core 220 recovers from the second position to the first position under the action of the elastic member 230, and the fluid channel 211 of the valve seat 210 is in a closed state.

[0050] As can be seen from the above, the plug-in portion 111 is plugged and connected to the valve seat 210. With this arrangement, the staff can quickly install and disassemble the water pressure sensor 100. At the same time, the on-off valve body 200 also has a self-sealing function. When the staff quickly disassembles the water pressure sensor 100, the on-off valve body 200 can automatically be in a closed state. Therefore, the staff does not need to shut down the liquid cooling delivery system. It can be seen that the water pressure sensor 100 and the on-off valve body 200 adopt the above-mentioned connection structure, and the on-off valve body 200 has a self-sealing function. The staff can conveniently and quickly repair or replace the water pressure sensor 100, which reduces the workload of the staff.

[0051] Moreover, compared to the common threaded connection method, in the present application, even if the staff frequently installs and disassembles the water pressure sensor 100, since the plug-in and clamping connection method is adopted between the plug-in part 111 and the valve seat 210, the friction damage between the plug-in part 111 and the valve seat 210 is small, so there is no need to worry about the damage between the two during disassembly and installation, thereby ensuring that the plug-in part 111 and the valve seat 210 can always maintain a tight connection.

[0052] In some embodiments, reference Figure 2 and Figure 3 The water pressure detection device also includes a sealing ring 300, which is arranged on the circumferential surface of the plug-in part 111 facing the valve seat 210, or the sealing ring 300 is arranged on the circumferential surface of the valve seat 210 facing the plug-in part 111. Therefore, when the plug-in part 111 and the valve seat 210 are plugged in and snap-connected, the sealing ring 300 is sealed and connected between the plug-in part 111 and the valve seat 210.

[0053] It should be noted that the plug-in portion 111 and the valve seat 210 are connected by plug-in and snap-fitting. On this basis, the present application also introduces a sealing ring 300. The sealing ring 300 ensures the sealing between the plug-in portion 111 and the valve seat 210, thereby ensuring the sealing between the water pressure sensor 100 and the on-off valve body 200 when connected, compensating for the problem that the above-mentioned connection method may have insufficient sealing. The plug-in and snap-fitting connection method of the plug-in portion 111 and the valve seat 210 of the present application can be better implemented.

[0054] In order to realize the plug-in connection between the plug-in portion 111 and the valve seat 210, in a possible embodiment, refer to Figure 2 and Figure 3 The plug-in portion 111 is plugged into the fluid channel 211, and the push rod portion 112 is connected to the end of the plug-in portion 111. Therefore, the push rod portion 112 extends into the fluid channel 211 when the plug-in portion 111 is plugged into the valve seat 210, thereby acting on the valve core 220. Under the action of the push rod portion 112, the valve core 220 switches from the first position to the second position, and the fluid channel 211 switches from a closed state to an open state.

[0055] At the same time, the sealing ring 300 is sealed and connected between the outer circumference of the plug-in part 111 and the inner circumference of the fluid passage 211. Specifically, the outer circumference of the plug-in part 111 is provided with an annular groove 1112, and the sealing ring 300 is arranged in the annular groove 1112, so as to be installed on the outer circumference of the plug-in part 111. After the plug-in part 111 is plugged into the fluid passage 211 of the valve seat 210, the sealing ring 300 is just sealed and connected between the outer circumference of the plug-in part 111 and the inner circumference of the valve seat 210, so as to seal the gap between the plug-in part 111 and the valve seat 210.

[0056] In other possible embodiments, the plug-in portion 111 is an annular sleeve (not shown in the figure), and the push rod portion 112 is located on the inner side of the plug-in portion 111. As a result, the push rod portion 112 extends into the fluid channel 211 when the plug-in portion 111 is plugged into the valve seat 210, thereby acting on the valve core 220. Under the action of the push rod portion 112, the valve core 220 switches from the first position to the second position, and the fluid channel 211 switches from a closed state to an open state.

[0057] At the same time, the sealing ring 300 is sealed and connected between the inner circumference of the plug-in portion 111 and the outer circumference of the fluid channel 211. Specifically, the outer circumference of the valve seat 210 is provided with an annular groove 1112, and the sealing ring 300 is arranged in the annular groove 1112, so as to be installed on the outer circumference of the valve seat 210. When the plug-in portion 111 and the valve seat 210 are plugged and matched, the sealing ring 300 is just sealed and connected between the outer circumference of the valve seat 210 and the inner circumference of the plug-in portion 111, so as to seal the gap between the plug-in portion 111 and the valve seat 210.

[0058] In some embodiments, reference Figure 3 and Figure 4 , a valve 240 is arranged inside the fluid channel 211, and the valve 240 and the valve seat 210 can be an integrated component or two separate components, which is not limited in this application. The valve 240 is provided with a connecting hole 241 that runs through both sides thereof, and the valve core 220 is slidably arranged in the valve seat 210 along the fluid channel 211, and is located on the side of the valve 240 away from the water pressure sensor 100. The elastic member 230 can be a compression spring, and is arranged on the side of the valve core 220 away from the valve 240, and one end of the elastic member 230 away from the valve core 220 abuts against the step surface on the side wall of the fluid channel 211, and the other end abuts against the side of the valve core 220 away from the valve 240, thereby, the elastic member 230 acts on the valve core 220 in the direction of the valve 240.

[0059] Wherein, under the action of the elastic member 230, when the valve core 220 is located at the first position, the valve core 220 is attached to the valve 240 to close the connecting hole 241 (refer to Figure 4); When the plug-in portion 111 is plugged and connected to the valve seat 210, the push rod portion 112 is inserted into the connecting hole 241 to overcome the elastic force of the elastic member 230 to push the valve core 220 to slide from the first position to the second position, and the valve core 220 is separated from the valve 240 to release the closure of the connecting hole 241 (refer to Figure 3 ).

[0060] Specifically, when the water pressure sensor 100 is not connected to the on-off valve body 200, the valve core 220 is attached to the side of the valve 240 under the action of the elastic member 230, and blocks the connection hole 241 on the valve 240, so that the valve 240 is in a closed state, and then the fluid channel 211 is in a closed state. When the water pressure sensor 100 is connected to the on-off valve body 200, the push rod 112 passes through the connection hole 241 and acts on the valve core 220, and the valve core 220 moves away from the valve 240 under the action of the push rod 112, and the valve 240 switches from a closed state to an open state. At this time, the liquid cooling delivery system inputs liquid water into the fluid channel 211 of the valve seat 210, and the liquid cooling water passes through the gap between the valve core 220 and the valve seat 210 and the connection hole 241 along the fluid channel 211 in sequence, and then flows into the water pressure sensor 100, and then detects the water pressure of the liquid cooling delivery system.

[0061] In order to achieve that liquid cooling water can pass through valve 240, in one possible embodiment, refer to Figure 3 The cross-sectional dimension of the connecting hole 241 is greater than the cross-sectional dimension of the push rod portion 112. With such an arrangement, when the push rod portion 112 acts on the valve core 220 through the connecting hole 241, a gap is reserved between the push rod portion 112 and the side wall of the connecting hole 241. Therefore, when the valve core 220 and the valve 240 are in a separated state, liquid cooling water can flow to the water pressure sensor 100 through the connecting hole 241.

[0062] In another possible embodiment, the connecting hole 241 includes a plug hole and a flow channel hole (not shown in the figure), and the plug hole and the flow channel hole can be arranged at intervals or integrated together, which is not limited in the present application. Specifically, when the water pressure sensor 100 is connected to the on-off valve body 200, the top rod portion 112 is passed through the plug hole to act on the valve core 220, and the valve core 220 moves away from the valve 240. Therefore, the valve core 220 releases the closure of the flow channel hole, and liquid cooling water can flow to the water pressure sensor 100 through the flow channel hole. It should be noted that when the valve core 220 is attached to the valve 240, the valve core 220 simultaneously closes the plug hole and the flow channel hole, thereby achieving the closure of the valve 240.

[0063] In order to ensure the sealing performance of the valve core 220 to the connecting hole 241, in some embodiments, refer to Figures 2 to 4The on-off valve body 200 further includes a sealing gasket 250, which is arranged on a side of the valve core 220 close to the valve 240. The sealing gasket 250 closes the connecting hole 241 when the valve core 220 is in the first position (refer to Figure 4 ). The sealing gasket 250 may be a rubber gasket or other types of sealing gaskets 250. It is understandable that when the push rod portion 112 releases the restriction on the valve core 220, the valve core 220 moves toward the valve 240 under the action of the elastic member 230, and the sealing gasket 250 moves toward the valve 240 synchronously with the valve core 220 to fit the surface of the valve 240. At this time, the valve core 220 blocks the connecting hole 241 through the sealing gasket 250. It should be noted that the sealing gasket 250 and the valve 240 can fit tightly, so that the connecting hole 241 can be tightly sealed, thereby making the on-off valve body 200 in a self-sealing state.

[0064] In order to ensure the sealing performance of the valve core 220 to the connecting hole 241, in some embodiments, refer to Figure 5 and Figure 6 The valve core 220 is provided with a spherical surface, and the end of the connection hole 241 close to the valve core 220 has a spherical port. When the valve core 220 is located at the first position, the spherical surface of the valve core 220 fits the spherical port of the connection hole 241, so that the valve core 220 can tightly seal the spherical port to close the connection hole 241, and the above-mentioned sealing gasket 250 does not need to be additionally provided.

[0065] Among them, refer to Figure 5 The valve core 220 is a steel ball, so the valve core 220 has a spherical surface to fit the spherical port, and the valve core 220 can tightly seal the spherical port. Figure 6 The valve core 220 has a spherical protrusion 221, and the spherical protrusion 221 has a spherical surface to fit the spherical port. The valve core 220 can tightly seal the spherical port.

[0066] In some embodiments, the elastic member 230 is further configured to keep the plug-in portion 111 in a snap connection with the valve seat 210. Specifically, when the water pressure sensor 100 is snap-connected with the on-off valve body 200, the push rod portion 112 acts on the valve core 220, thereby acting on the elastic member 230, and the elastic member 230 reacts on the push rod portion 112 by the valve core 220, thereby acting on the plug-in portion 111 of the water pressure sensor 100, so that the plug-in portion 111 is stably snap-connected with the valve seat 210 under the action of the elastic member 230.

[0067] In some embodiments, reference Figure 1 and Figure 2The side of the valve seat 210 is provided with a guide groove 212 and a limit groove 213, which can be arranged on the inside or outside of the valve seat 210 or pass through the inside and outside of the valve seat 210, wherein the guide groove 212 is extended substantially along the axial direction of the valve seat 210, one end of the guide groove 212 passes through the end of the valve seat 210 close to the water pressure sensor 100, and the other end of the guide groove 212 is connected to the limit groove 213, and the limit groove 213 is extended substantially along the circumferential direction of the valve seat 210. At the same time, the side wall of the plug-in portion 111 is provided with a boss 1111, and when the plug-in portion 111 is plugged and connected with the valve seat 210, the boss 1111 slides into the limit groove 213 along the guide groove 212.

[0068] Specifically, when the water pressure sensor 100 is connected to the on-off valve body 200, the plug-in portion 111 is inserted into the fluid channel 211 through the port of the valve seat 210 (refer to Figure 3 ), and the boss 1111 slides into the guide groove 212 from the end of the guide groove 212 and slides along the guide groove 212. When the boss 1111 slides to the connection position between the guide groove 212 and the limiting groove 213, the plug-in portion 111 stops sliding toward the fluid channel 211. Then, the staff rotates the water pressure sensor 100 circumferentially, and the boss 1111 slides into the limiting groove 213. At this time, the limiting groove 213 limits the axial sliding of the boss 1111, so that the plug-in portion 111 is connected to the valve seat 210 by snapping, so that the water pressure sensor 100 is connected to the on-off valve body 200.

[0069] It should be noted that, through the setting of the elastic member 230, the elastic member 230 pushes the boss 1111 and the limiting groove 213 close to the side of the water pressure sensor 100 to tightly abut against each other to prevent the boss 1111 from sliding into the guide groove 212, thereby ensuring that the boss 1111 is firmly clamped in the limiting groove 213, and further ensuring that the water pressure sensor 100 and the on-off valve body 200 are firmly connected.

[0070] Further, a notch 214 is provided on one side of the limiting groove 213 close to the water pressure sensor 100, and the width of the notch 214 in the circumferential direction is substantially the same as the width of the boss 1111 in the circumferential direction, so that the boss 1111 is at least partially embedded in the notch 214 under the action of the elastic member 230. It can be understood that, through the setting of the notch 214, after the boss 1111 slides into the limiting groove 213, it is located at the position corresponding to the notch 214. At this time, the plug-in portion 111 slides outward under the action of the elastic member 230, so that the boss 1111 is embedded in the notch 214. At this time, the notch 214 limits the circumferential rotation of the boss 1111, thereby limiting the boss 1111 from sliding into the guide groove 212, thereby ensuring that the boss 1111 is firmly clamped on the valve seat 210, so that the water pressure sensor 100 is firmly connected to the on-off valve body 200.

[0071] In a further embodiment, the guide groove 212 is arranged to extend obliquely along the circumferential direction of the valve seat 210. It is understandable that when the plug-in portion 111 is inserted into the fluid channel 211, the boss 1111 slides obliquely along the guide groove 212 in the circumferential direction, so the guide groove 212 provides an inertial force in the circumferential direction to the boss 1111. It can be seen that when the boss 1111 slides to the connection position between the guide groove 212 and the limiting groove 213, the inertial force of the boss 1111 in the circumferential direction can smoothly slide into the limiting groove 213, and then the water pressure sensor 100 can be conveniently installed on the on-off valve body 200.

[0072] In some embodiments, reference Figure 1 and Figure 2 The water pressure sensor 100 includes a sensor body 110 and a connecting valve body 120. The plug-in portion 111 and the push rod portion 112 are arranged on the sensor body 110. It can be seen that the sensor body 110 is connected to the on-off valve body 200, so as to receive the liquid cooling water delivered from the on-off valve body 200 to detect the water pressure of the liquid cooling delivery system. The connecting valve body 120 is connected to the sensor body 110, and the on-off valve body 200 and the connecting valve body 120 are equivalent to forming a male and female connector to control the flow of the liquid cooling delivery system.

[0073] It can be understood that the on-off valve body 200 can be equivalent to a female connector, the connecting valve body 120 can be equivalent to a male connector, and the male connector is integrated in the water pressure sensor 100. It can be seen that the water pressure sensor 100 can not only be used to detect the water pressure of liquid cooling water when applied, but also used as a male connector to cooperate with the female connector to control the flow of the liquid cooling delivery system.

[0074] Furthermore, the sensor body 110 is integrally connected to the connecting valve body 120, or in other words, the water pressure sensor 100 is integrated in the connecting valve body 120 (equivalent to a male connector). With this arrangement, the water pressure sensor 100 is equivalent to being used as a male connector, and the water pressure sensor 100 is convenient to install and disassemble.

[0075] Furthermore, the connecting valve body 120 is connected to the sensor body 110 by welding, bonding, threading or bolting. In this way, the sensor body 110 and the connecting valve body 120 are connected in an integrated manner, which is equivalent to saying that the water pressure sensor 100 is integrated with the connecting valve body 120 (equivalent to a male connector). Therefore, the water pressure sensor 100 can be used as a male connector, and the water pressure sensor 100 is easy to install and disassemble. Of course, the connecting valve body 120 and the sensor body 110 can also be independent mechanisms, and flexible installation and disassembly operations can be performed between the two.

[0076] The present application discloses a liquid cooling delivery system, including the above-mentioned water pressure detection device. Specifically, the liquid cooling delivery system adopts the above-mentioned water pressure detection device. If the water pressure detection device is in use, the plug-in portion 111 is plugged and connected with the valve seat 210, and the push rod portion 112 overcomes the elastic force of the elastic member 230, pushes the valve core 220 to remain in the second position, and the fluid channel 211 of the valve seat 210 is in an open state. Therefore, the liquid cooling delivery system flows liquid cooling water from the fluid channel 211 into the water pressure sensor 100, and the water pressure sensor 100 detects the water pressure of the liquid cooling delivery system. If the water pressure sensor 100 needs to be repaired or replaced, since the plug-in portion 111 is plugged and snap-connected to the valve seat 210, the staff can easily separate the plug-in portion 111 from the valve seat 210, thereby quickly disassembling the water pressure sensor 100 from the on-off valve body 200 to repair or replace the water pressure sensor 100; wherein, during the disassembly process of the water pressure sensor 100, the push rod portion 112 releases the restriction on the valve core 220, at which time, the valve core 220 recovers from the second position to the first position under the action of the elastic member 230, and the fluid channel 211 of the valve seat 210 is in a closed state.

[0077] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
