[0028] like Figures 1 to 4 As shown, some embodiments of the present application provide a composite valve having a first direction X, a second direction Y and a third direction Z intersecting with each other.

[0029] In this embodiment, the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0030] The composite valve includes a valve seat 100 and a valve core 200 .

[0031] The valve seat 100 is provided with at least two first connection holes 110 along the first direction X. It is understandable that the number of the first connection holes 110 can be two or more than two, and can be specifically set according to actual conditions.

[0032] Exemplarily, in some embodiments, there are two first connection holes, and the two first connection holes 110 are arranged at intervals along the third direction Z. One of the two first connection holes 110 is used to connect to the cold water tank, and the other first connection hole 110 is used to connect to the hot water tank, thereby satisfying the user's demand for temperature control to achieve the purpose of providing cooling or heating treatment to the patient.

[0033] It should be noted that, in other embodiments, the valve seat 100 is provided with a plurality of first connection holes 110, and the plurality of first connection holes 110 are arranged at intervals along the third direction Z, and the distance between the axes of two adjacent first connection holes 110 can be specifically set according to actual conditions to adapt to the design of the multi-channel structure and meet the user's usage requirements.

[0034] In addition, in some other embodiments, the plurality of first connection holes 110 are arranged at equal intervals along the third direction Z to improve space utilization and enhance the uniformity and aesthetics of pipeline layout.

[0035] In this embodiment, the valve seat 100 is provided with a second connecting hole 120 on one side along the second direction Y, and the end of the second connecting hole 120 close to the first connecting hole 110 is connected to the first connecting hole 110. It can be understood that the axis of the first connecting hole 110 is perpendicular to the axis of the second connecting hole 120.

[0036] The valve seat 100 is provided with a first mounting hole 130 connected to the second connecting hole 120 on one side along the first direction X, and there is a gap between the first mounting hole 130 and the first connecting hole 110. It can be understood that one end of the first mounting hole 130 close to the second connecting hole 120 is connected to the first connecting hole 110 through the second connecting hole 120.

[0037] In addition, one end of the valve core 200 is arranged in the first mounting hole 130, and the valve core 200 is movably connected to the hole wall of the first mounting hole 130. It is worth noting that the connection method between the valve core 200 and the hole wall of the first mounting hole 130 includes any one of sliding connection, rotational connection, bonding, clamping, magnetic connection, threaded connection or bolt connection, or a combination of two or more of them, which can be specifically set according to actual conditions.

[0038] Specifically, in this embodiment, one end of the valve core 200 is rotatably connected to the hole wall of the first mounting hole 130, that is, the valve core 200 can rotate relative to the valve seat 100. Further, the valve core 200 rotates about the axis of the first mounting hole 130, that is, the axis of the valve core 200 coincides with the axis of the first mounting hole 130.

[0039] In addition, the valve core 200 is provided with a first guide hole 210 extending through it perpendicular to the first direction X. When the valve core 200 is rotated to a preset position relative to the valve seat 100, the first guide hole 210 is connected with the second connecting hole 120, and the hole wall of the second connecting hole 120 can be connected with an external medical temperature control bag, so that the liquid flowing through the second connecting hole 120 can enter the medical temperature control bag, thereby controlling the patient's body temperature by the liquid flowing through the temperature control bag.

[0040] In this embodiment, the aperture of the first guide hole 210 is equal to the aperture of the second connecting hole 120, and when the valve core 200 rotates to a preset position relative to the valve seat 100, the axis of the first guide hole 210 coincides with the axis of the second connecting hole 120, thereby ensuring that the flow rate of the liquid flowing through the second connecting hole 120 is equal to the flow rate of the liquid flowing through the first guide hole 210, thereby ensuring the stability of the liquid flowing in the second connecting hole 120 and the first guide hole 210.

[0041] It should be noted that when the valve core 200 rotates from a preset position relative to the valve seat 100, when the second connecting hole 120 and the first guide hole 210 are misaligned, a portion of the second connecting hole 120 is sealed by the outer wall of the valve core 200 to disconnect the liquid flowing through the second connecting hole 120, thereby forming a sealing structure to prevent the liquid flowing through the first connecting hole 110 from flowing through the second connecting hole 120.

[0042] It can be understood that the flow of liquid flowing through the second connecting hole 120 can be adjusted and controlled by rotating the valve core 200 to improve the control efficiency and convenience of the liquid flow flowing through the second connecting hole 120, and the valve seat 100 and the valve core 200 are movably connected to facilitate installation, disassembly or replacement.

[0043] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, the composite valve includes a first connector 300. Along the first direction X, the first connectors 300 are respectively provided at both ends of the first connection hole 110. The first connector 300 is connected to the hole wall of the first connection hole 110, that is, the first connector 300 is connected to the valve seat 100. It can be understood that the first connector 300 is a cylindrical structure.

[0044] The connection method between the first connector 300 and the valve seat 100 includes any one of threaded connection, clamping, bonding, welding or bolt connection, which can be specifically set according to actual conditions.

[0045] In this embodiment, threaded connection between the first connector 300 and the valve seat 100 can not only improve the stability and tightness of the connection between the first connector 300 and the valve seat 100, but also improve the installation or disassembly efficiency between the first connector 300 and the valve seat 100.

[0046] In addition, in the present embodiment, the first connector 300 is partially disposed in the first connecting hole 110, and the first connecting head 300 is penetrated by a first through hole 310 along the first direction X, the first through hole 310 is communicated with the first connecting hole 110, and the axis of the first through hole 310 coincides with the axis of the first connecting hole 110, so that an external flow guide pipe can be connected to the valve seat 100 through the first connector 300, so that liquid can flow through the first connecting hole 110 through the first through hole 310.

[0047] In addition, in some embodiments, a convex ring is provided on the circumference of the first connector 300 , the axis of the convex ring coincides with the axis of the first connector 300 , and the convex ring is arranged in the middle position of the first connector 300 along the first direction X.

[0048] like Figure 3 As shown, in some embodiments of the present application, the inner wall of the first connecting hole 110 is provided with a first annular protrusion 140, the axis of the first annular protrusion 140 coincides with the axis of the first connecting hole 110, and the first annular protrusion 140 is arranged in the middle position of the first connecting hole 110 along the first direction X, so that the first annular protrusion 140 forms a limiting effect on the first connecting head 300 installed in the first connecting hole 110, so as to ensure the accuracy and convenience of the installation of the first connecting head 300 on the valve seat 100.

[0049] In addition, a first sealing ring 400 is provided between the first connector 300 and the first annular protrusion 140. The first sealing ring 400 and the first annular protrusion 140 are coaxially arranged, and along the first direction X, one side of the first sealing ring 400 abuts against the first annular protrusion 140, and the other side of the first sealing ring 400 abuts against the first connector 300, so as to form a sealing connection structure between the first connector 300 and the first annular protrusion 140, so as to prevent the liquid flowing through the first connecting hole 110 from leaking from the gap between the first connector 300 and the valve seat 100, thereby improving the sealing quality between the first connector 300 and the valve seat 100.

[0050] It should be noted that the inner diameter of the first sealing ring 400 is equal to or smaller than the inner diameter of the first annular protrusion 140 to prevent the first sealing ring 400 from affecting the flow of liquid flowing through the first connecting hole 110, thereby ensuring the stability and smoothness of the flow through the first connecting hole 110.

[0051] like Figure 5As shown, in some embodiments of the present application, along the first direction X, a limiting step 131 is provided at one end of the first mounting hole 130 away from the second connecting hole 120, and the limiting step 131 is an annular step, and the side wall of the valve core 200 abuts against the limiting step 131, so as to provide a limiting effect on the valve core 200 through the limiting step 131. The limiting step 131 and the first mounting hole 130 are coaxially arranged.

[0052] It should be noted that, in the present application, the limiting step 131 is a conical limiting step.

[0053] like Figure 3 and Figure 6 As shown, in some embodiments of the present application, the valve core 200 includes a valve body 220 and a cover body 230. The connection between the valve body 220 and the cover body 230 includes any one or a combination of two or more of snap connection, bonding, threaded connection, bolt connection, magnetic connection, sliding connection, hinge connection, and abutment, which can be specifically set according to actual conditions.

[0054] The valve body 220 is provided with the first flow guide hole 210, and it can be understood that when the valve body 220 is rotated to a preset position, the first flow guide hole 210 can be connected with the second connection hole 120. In addition, when the valve body 220 is rotated from the preset position to another position, the first flow guide hole 210 and the second connection hole 120 are misaligned, and the first flow guide hole 210 and the second connection hole 120 are not connected, the second connection hole 120 can be partially sealed by the outer wall of the valve body 220 to block the liquid flowing through the second connection hole 120, forming a water channel closed structure.

[0055] In this embodiment, the valve body 220 is partially disposed in the first mounting hole 130 , and the valve body 220 is rotatably connected to the hole wall of the first mounting hole 130 . Specifically, the valve body 220 can rotate around the axis of the first mounting hole 130 as the rotation axis.

[0056] In addition, a second annular protrusion 240 abutting against the limiting step 131 is provided on the circumferential side of the valve body 220, so that the limiting step 131 forms a limiting effect on the second annular protrusion 240 to ensure the accuracy and stability of the installation position of the valve body 220 in the first mounting hole 130. By abutting the limiting step 131 against the second annular protrusion 240, the tightness of the contact between the valve body 220 and the hole wall of the first mounting hole 130 is improved, thereby improving the sealing quality.

[0057] In this embodiment, the cover body 230 is disposed on a side of the second annular protrusion 240 away from the first air guide hole 210 , and the cover body 230 abuts against the second annular protrusion 240 and is connected to the limiting step 131 .

[0058] like Figure 3 and Figure 6 As shown, in some embodiments of the present application, at least one second annular groove 241 is provided on the circumferential side of the second annular protrusion 240. It can be understood that the number of the second annular grooves 241 can be one, two or any number above two, which can be specifically set according to actual conditions.

[0059] In some embodiments, the number of the second annular groove 241 is one, and the second annular groove 241 is disposed at a middle position of the second annular protrusion 240 along the first direction X.

[0060] In some other embodiments, there are multiple second annular grooves 241 , and the multiple second annular grooves 241 are arranged along the first direction X at intervals.

[0061] It is worth noting that the depth of the second annular groove 241 is smaller than the thickness of the second annular protrusion 240 .

[0062] Among them, a second annular seal 600 is provided in the second annular groove 241, and the outer wall of the second annular seal 600 abuts against the inner wall of the second annular groove 241, and the side of the second annular seal 600 facing away from the second annular protrusion 240 abuts against the limiting step 131, so as to form a sealing connection structure through the groove wall of the second annular groove 241, the outer wall of the second annular seal 600 and the limiting step 131, so as to further improve the sealing quality of the connection between the valve core 200 and the valve seat 100, so as to prevent the liquid flowing through the second connecting hole 120 from leaking from the first mounting hole 130.

[0063] In addition, it should be noted that the number of the second annular grooves 241 is equal to the number of the second annular seals 600 , and one second annular seal 600 is correspondingly disposed in one second annular groove 241 .

[0064] like Figure 3 and Figure 6 As shown, in some embodiments of the present application, along the first direction X, the cover body 230 is provided with a clearance opening 231, one end of the valve body 220 is at least partially exposed from the clearance opening 231, and the end of the valve body 220 close to the clearance opening 231 is provided with a connecting portion 221 so that a user can connect the connecting portion 221 through a tool and rotate the valve body 220.

[0065] The connection portion 221 may be one of a slot, a cross slot, a slotted protrusion, a cross protrusion, a hexagonal screw hole or a hexagonal boss, and may be specifically set according to actual conditions.

[0066] In this embodiment, the connecting portion 221 is a straight slot. It is understandable that the user can connect the straight slot with a screwdriver and rotate the valve body 220 with the screwdriver to adjust the conduction or closing of the valve core 200 to the second connecting hole 120.

[0067] like Figure 1 and Figure 3 As shown, in some embodiments of the present application, the cover body 230 is sleeved on one end of the valve body 220 away from the valve seat 100, and the cover body 230 is connected to the limiting step 131. The connection between the cover body 230 and the limiting step 131 includes any one or a combination of two or more of threaded connection, bolt connection, clamping, bonding, hinged connection or interference fit, which can be specifically set according to actual conditions.

[0068] In this embodiment, the cover body 230 and the limiting step 131 are threadedly connected, which can not only ensure the stability of the connection between the cover body 230 and the limiting step 131, but also improve the installation or disassembly efficiency between the cover body 230 and the limiting step 131, that is, ensure the stability of the connection between the cover body 230 and the valve seat 100 and the installation or disassembly efficiency.

[0069] The inner wall of the cover body 230 and the outer wall of the valve body 220 form an annular channel 250, in which an elastic member 500 is provided, one end of the elastic member 500 abuts against the second annular protrusion 240, and the other end of the elastic member 500 abuts against one end of the cover body 230 close to the connecting portion 221.

[0070] It should be noted that the elastic member 500 is in a compressed state in the annular channel 250, so as to provide elastic force to the valve core 200 through the elastic member 500, so that the valve body 220 always has a tendency to move along the first direction X toward the bottom of the first mounting hole 130, thereby further ensuring the stability of the valve body 220 in the first mounting hole 130, preventing the valve body 220 from moving or shaking in the first mounting hole 130, and ensuring the accuracy and stability of the liquid flow control through the second connecting hole 120 by the valve body 220.

[0071] like Figure 1 and Figure 2 As shown, in some embodiments of the present application, the valve seat 100 is provided with four first connecting holes 110, four first mounting holes 130, four second connecting holes 120 and four first flow guide holes 210, and the four first connecting holes 110, the four first mounting holes 130, the four second connecting holes 120 and the four first flow guide holes 210 are respectively arranged at intervals along the third direction Z.

[0072] In this embodiment, the four first connection holes 110 are respectively used for cold water output, hot water output, cold water return and hot water return.

[0073] It can be understood that along the third direction Z, the distance between the axes of two adjacent first connecting holes 110, the distance between the axes of two adjacent first mounting holes 130, the distance between the axes of two adjacent second connecting holes 120, and the distance between the axes of two adjacent first guide holes 210 are respectively equal, thereby forming multiple guide structures on the valve seat 100, thereby being able to meet the different needs of users.

[0074] like Figure 5 As shown, in some embodiments of the present application, along the second direction Y, a second mounting hole 170 is provided on one side of the valve seat 100, the second mounting hole 170 is provided at one end of the second connecting hole 120 away from the first connecting hole 110, the second mounting hole 170 and the second connecting hole 120 are coaxially arranged, and the aperture of the second mounting hole 170 is larger than the aperture of the second connecting hole 120. It should be noted that there is a gap between the second mounting hole 170 and the first mounting hole 130.

[0075] like Figure 3 and Figure 5 As shown, in some embodiments of the present application, along the second direction Y, a second connecting head 700 is provided in the second mounting hole 170, wherein the connection method between the second connecting head 700 and the hole wall of the second mounting hole 170 includes any one of threaded connection, bolt connection, snap connection, bonding, hinged connection or interference fit, or a combination of two or more thereof, which can be specifically set according to actual conditions.

[0076] In this embodiment, the second connecting head 700 and the hole wall of the second mounting hole 170 are threadedly connected, which can not only ensure the stability of the connection between the second connecting head 700 and the hole wall of the second mounting hole 170, but also improve the installation or disassembly efficiency between the second connecting head 700 and the valve seat 100, that is, ensure the stability of the connection between the second connecting head 700 and the valve seat 100 and the installation or disassembly efficiency.

[0077] In addition, the second connecting head 700 is penetrated by a second guide hole 710 along the second direction Y, and the second guide hole 710 is connected to the second connecting hole 120 so that the liquid flowing through the second connecting hole 120 can flow into the second guide hole 710 and be discharged from the second guide hole 710.

[0078] Among them, the axis of the second guide hole 710 coincides with the axis of the second connecting hole 120, and the aperture of the second guide hole 710 is larger than the aperture of the second connecting hole 120, so that the liquid in the second connecting hole 120 can form a slow flow effect when entering the second guide hole 710, thereby controlling the flow rate and stability of the liquid.

[0079] It should be noted that the second connector 700 is provided with a connecting end at one end away from the valve seat 100 , and the connecting end can be communicated with an external pipeline.

[0080] Optionally, in some embodiments of the present application, along the third direction Z, a first connection portion 150 is provided on one side of the valve seat 100 , and a second connection portion 160 is provided on the other side of the valve seat 100 , and the first connection portion 150 can be connected to the second connection portion 160 .

[0081] The connection method between the first connection part 150 and the second connection part 160 includes any one of snap connection, bonding, magnetic connection, threaded connection, and bolt connection, which can be specifically set according to actual conditions.

[0082] Exemplarily, in some embodiments, the first connecting part 150 is a first magnet, the second connecting part 160 is a second magnet, and the first magnet and the second magnet attract each other with opposite poles; in other embodiments, the first connecting part 150 is a first adhesive layer, the second connecting part 160 is a second adhesive layer, and the first adhesive layer and the second adhesive layer are bonded to each other; in yet other embodiments, the first connecting part 150 is a nut, the second connecting part 160 is a screw hole, and the nut and the wall of the screw hole are threadedly connected.

[0083] It can be understood that by detachably connecting the first connecting part 150 and the second connecting part 160, two adjacent valve seats 100 can be connected, thereby increasing the number of valve seats 100 and improving the convenience of increasing or reducing the valve seats 100 to meet the different needs of users during use and enhance the user experience.

[0084] Since some angular deviations may occur when the user rotates the valve body 220 to a preset position relative to the valve seat 100, the axis of the second connecting hole 120 and the axis of the first guide hole 210 do not completely coincide, resulting in a flow rate through the second connecting hole 120 and a flow rate through the first guide hole 210 being different, affecting the smoothness and stability of the liquid flowing in the second connecting hole 120 and the first guide hole 210.

[0085] Based on this, Figure 5 and Figure 7As shown, in some embodiments of the present application, the inner wall of the first mounting hole 130 is provided with a first limiting portion 800 , and the side wall of the valve body 220 is provided with a second limiting portion 900 , and the first limiting portion 800 can abut against the second limiting portion 900 .

[0086] It should be noted that, when the user rotates the valve body 220 with a screwdriver, when the valve body 220 rotates to the preset position relative to the valve seat 100, the first limiting portion 800 abuts against the second limiting portion 900, so that the first limiting portion 800 limits the second limiting portion 900, thereby limiting the valve body 220 through the first limiting portion 800, so as to prevent the valve body 220 from continuing to rotate. In other words, when the valve body 220 rotates to the preset position, at this time, the second connecting hole 120 and the first guide hole 210 are connected, so that the composite valve is opened, that is, the liquid flowing through the first connecting hole 110 can pass through the second connecting hole 120 and the first guide hole 210, and be discharged from the second mounting hole 170.

[0087] It can be understood that, by setting the first limit portion 800 and the second limit portion 900, the accuracy of the rotation angle of the valve body 220 can be ensured when the user rotates the valve body 220, thereby ensuring that the axis of the second connecting hole 120 and the axis of the first guide hole 210 coincide with each other when the valve body 220 is rotated to a preset position, thereby ensuring the accuracy and stability of the opening of the composite valve, and effectively improving the efficiency and convenience of rotating and opening the valve body 220.

[0088] In some embodiments of the present application, the first limiting portion 800 is an arc-shaped groove, the center of which is located on the axis of the first mounting hole 130, and the arc length of the arc-shaped groove can be specifically set according to actual conditions.

[0089] In addition, the second limiting portion 900 is a protrusion, and the protrusion is received in the arc-shaped groove, so that the groove wall of the arc-shaped groove can limit the rotation angle of the protrusion.

[0090] It should be noted that, in the present embodiment, when the valve body 220 rotates to a preset position relative to the valve seat 100, the protrusion abuts against the groove wall at one end of the arc groove along the arc length direction, so as to limit the protrusion through the groove wall of the arc groove, so as to ensure the accuracy of connecting the first guide hole 210 and the second connecting hole 120 during the rotation of the valve body 220 relative to the valve seat 100.

[0091] In other embodiments, when the valve body 220 rotates from a preset position to a closed position relative to the valve seat 100, the protrusion abuts against the groove wall at the other end of the arc groove along the arc length direction, so as to form a limit on the protrusion through the groove wall at the other end of the arc groove, so as to shorten the rotation angle of the valve body 220 relative to the valve seat 100, thereby improving the accuracy and speed of sealing the water path flowing through the second connecting hole 120, improving the user experience, and effectively ensuring the quality of the water path sealing.

[0092] It should be noted that the closed position described in this embodiment refers to the misalignment of the first guide hole 210 and the second connecting hole 120, and the valve body 220 seals and disconnects the second connecting hole 120 to prevent liquid from flowing from the second connecting hole 120 into the second mounting hole 170, that is, the position of the valve body 220 relative to the valve seat 100 when the water path flowing through the second connecting hole 120 is closed.

[0093] In a second aspect, some embodiments of the present application provide a pipeline structure, including a pipe body and at least one composite valve. It is understandable that the number of composite valves provided in the pipe body can be one, two or more than two, and can be specifically set according to actual conditions.

[0094] Specifically, the number of compound valves may be determined according to the number of beds in the ward, wherein one compound valve corresponds to one bed.

[0095] It can be understood that by setting the composite valve in the pipe body and setting the pipe body in the ward, the water supply system or medical temperature control equipment can be set outside the ward, which not only reduces the noise generated during the operation of the temperature control equipment, but also ensures the simplicity of the ward and improves the user experience.

[0096] In a third aspect, some embodiments of the present application provide a medical temperature control device, comprising the composite valve described in any one of the above embodiments or the pipeline structure described in any one of the above embodiments.

[0097] It can be understood that the medical temperature control device has the beneficial effects of the composite valve described in any of the above embodiments, as well as the beneficial effects of the pipeline structure described in any of the above embodiments, which will not be described one by one here.

[0098] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0099] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0100] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
