[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0050] The utility model discloses a liquid discharge device.

[0051] A liquid outlet device comprises a liquid outlet component 1, a mounting mechanism 2 and an adjusting mechanism 3. The liquid outlet component 1 can be detachably mounted on the mounting mechanism 3, the adjusting mechanism 3 is arranged outside the liquid outlet component, and the on-off of the liquid outlet component is controlled by the outside of the liquid outlet component. The adjusting mechanism 3 can also linearly adjust the liquid outlet flow rate of the liquid outlet component, and adjust the liquid flow rate as needed according to the size of the liquid required position.

[0052] The liquid outlet components 1 include at least two groups, which are independent of each other. The independent liquid outlet components are respectively controlled by the regulating mechanism, which controls the on / off and liquid outlet flow of each liquid outlet component.

[0053] The mounting mechanism 2 is used to install the liquid outlet component 1, and the liquid outlet component 1 can be detachably mounted on the mounting mechanism 2, so that the liquid outlet component 1 can be quickly installed on the mounting mechanism or removed from the mounting mechanism, and it is convenient for medical staff to replace the liquid outlet component or sterilize the liquid outlet component regularly, and the operation is simple and fast.

[0054] The regulating mechanism 3 includes a regulating component 32, which is used to regulate the liquid discharge state of the liquid discharge component 1. Moreover, the regulating component 32 is arranged outside the liquid discharge component 1, and the regulating component regulates the liquid discharge state of each liquid discharge component by applying a pressing force to each liquid discharge component from the outside of the liquid discharge component.

[0055] The regulating component regulates the liquid discharge state of the liquid discharge component from the outside of the liquid discharge component. The regulating component does not directly contact the liquid inside the liquid discharge component, thereby avoiding liquid contamination and maintaining a sterile environment inside the liquid discharge component.

[0056] The regulating component adjusts the liquid discharge state of each liquid discharge component by applying pressing force to each liquid discharge component from the outside of the liquid discharge component. The regulating operation is simple and convenient, and has low requirements on the structure of the liquid discharge component. The regulating component and the liquid discharge component are independent of each other, which is convenient for separate replacement or loading and unloading of the liquid discharge component.

[0057] The liquid outlet components are detachably mounted on the mounting mechanism, and the regulating components adjust the liquid outlet state of each liquid outlet component by applying a pressing force to each liquid outlet component from the outside of the liquid outlet component. When the liquid outlet components are in a fully open state, that is, the regulating mechanism does not apply a pressing force to all liquid outlet components, each liquid outlet component is relaxed, and each liquid outlet component can be removed from the mounting mechanism or quickly installed on the mounting mechanism. After the liquid outlet components are removed, medical staff can disinfect the liquid outlet components to ensure regular disinfection of the liquid outlet components and ensure a sterile environment for the liquid outlet components.

[0058] The liquid outlet state includes a liquid outlet component fully open state, a liquid outlet component fully closed state, and a state where only one liquid outlet component is open.

[0059] When the liquid outlet assembly is in the fully open state, each liquid outlet assembly can be quickly removed from the mounting mechanism. Similarly, when the adjustment assembly is in the state of keeping the liquid outlet assembly in the fully open state, each liquid outlet assembly can be quickly installed on the mounting mechanism, and the installation operation is simple and fast. After the liquid outlet assembly is removed from the mounting mechanism, the medical staff can sterilize and disinfect the liquid outlet assembly, which is simple and convenient to operate and can ensure the sterilization effect. At the same time, other structural components connected to the liquid outlet assembly will not be contaminated during the sterilization process.

[0060] The liquid outlet components are in a fully closed state, that is, all liquid outlet components are cut off, and no liquid flows through the liquid outlet components temporarily.

[0061] Only one liquid outlet component is in the open state, that is, only the liquid outlet channel of one liquid outlet component is opened, and the liquid outlet channels of the remaining liquid outlet components are all cut off. The liquid outlet flow rate in the liquid outlet component with the liquid outlet channel opened can be linearly adjusted by the adjustment component to achieve on-demand adjustment of the liquid flow rate.

[0062] The liquid outlet components installed on the mounting mechanism are synchronously adjusted through the adjustment mechanism, so that each liquid outlet component can be switched between a fully open state, a fully closed state and a state where only one liquid outlet component is open, thereby meeting the infusion on-off requirements of different handles on dental treatment equipment that integrates multiple treatment functions.

[0063] The regulating component 32 synchronously regulates all the liquid outlet components 1. When the regulating component is in operation, it can act on all the liquid outlet components at the same time to adjust the liquid outlet components and adjust the liquid outlet state of the liquid outlet components. Of course, the liquid outlet components whose liquid outlet state is adjusted do not necessarily change the liquid outlet state. For example, when adjusting the liquid outlet flow rate of a liquid outlet component, the liquid outlet state of the remaining liquid outlet components remains in a closed state.

[0064] In this solution, the regulating component 32 synchronously regulates all the liquid outlet components 1 to achieve the purpose and function of one regulating component to simultaneously regulate multiple liquid outlet components. At the same time, the liquid outlet components that need to be turned on can be selected as needed, and all other liquid outlet components can be turned off or kept in a closed state.

[0065] The regulating mechanism 3 is installed on the mounting mechanism 2, so that the regulating mechanism is installed near the liquid outlet component, making the overall structure of the liquid outlet device compact.

[0066] Based on the above technical solution, the liquid passing through the liquid outlet component includes but is not limited to physiological saline, purified water, hydrogen peroxide, distilled water, mineral water, etc., and medical staff can choose as needed.

[0067] In one embodiment, Figure 1 and Figure 2 As shown, the liquid outlet assembly 1 includes a liquid outlet hose 11, which is used to transport liquid and has a simple structure, low cost, and is easy to install and replace. Furthermore, the liquid outlet hose is preferably an integrated tube to reduce pipe joints, reduce the risk of liquid leakage, and also reduce the risk of external bacteria entering the interior of each liquid outlet hose.

[0068] The liquid outlet hose 11 can be detachably mounted on the mounting mechanism 2, so that the liquid outlet hose can be quickly mounted on the mounting mechanism or removed from the mounting mechanism.

[0069] The regulating component applies a pressing force to the outer wall of the liquid outlet hose outside the liquid outlet hose, and the pressing force is along the radial direction of the liquid outlet hose, so that the effective area through which the liquid passes in the liquid outlet hose 11 changes, and the flow rate of the liquid passing in the liquid outlet hose changes. The regulating component changes the cross-sectional area of ​​the liquid outlet hose by pressing the liquid outlet hose, and the effective area through which the liquid passes in the liquid outlet hose changes, so that the liquid outflow rate of the liquid can be changed. Generally, when the liquid outlet hose is subjected to a radial pressing force, the cross-sectional area of ​​the liquid outlet hose decreases, and the effective area through which the liquid passes in the liquid outlet hose decreases, that is, the liquid outflow rate of the liquid outlet hose decreases. On the contrary, when the liquid outlet hose is relaxed, the effective area through which the liquid passes in the liquid outlet hose increases, that is, the liquid outflow rate of the liquid outlet hose increases.

[0070] In one embodiment, in order to simplify the structure of the liquid outlet hose and facilitate linear control of the liquid outlet flow rate of the liquid outlet hose, the cross section of the liquid outlet hose 11 is circular or elliptical.

[0071] In one embodiment, Figure 1 As shown, according to the use scope and treatment function of the dental treatment equipment, it is generally more appropriate to install two groups of liquid outlet components on one dental treatment equipment. In this solution, in order to facilitate the understanding of technical personnel in this field, in a specific embodiment, two groups of liquid outlet components are used as an example for explanation.

[0072] There are two groups of liquid outlet components, that is, there are two liquid outlet hoses. When the liquid outlet components are fully open, both liquid outlet hoses are fully open. When the liquid outlet components are fully closed, both liquid outlet hoses are completely cut off. When only one liquid outlet component is open, the upper liquid outlet hose is connected and the lower liquid outlet hose is cut off, or the upper liquid outlet hose is cut off and the lower liquid outlet hose is connected. Figure 6 The figure shows the process of the regulating component regulating the liquid outlet state of the two liquid outlet pipes. Figure 6 Schematic diagrams of four liquid outlet states of two liquid outlet hoses are shown in the figure, wherein (a) is the fully open state of the two liquid outlet hoses, wherein (b) is the fully closed state of the two liquid outlet hoses, wherein (c) is the upper liquid outlet hose connected state and the lower liquid outlet hose closed state, and wherein (d) is the upper liquid outlet hose closed state and the lower liquid outlet hose connected state.

[0073] like Figure 6 As shown, when the adjustment component adjusts the liquid outlet hose, the general adjustment process is: both liquid outlet hoses are fully open (a) → both liquid outlet hoses are fully closed (b) → the upper liquid outlet hose is connected and the lower liquid outlet hose is closed (c), or both liquid outlet hoses are fully open (a) → both liquid outlet hoses are fully closed (b) → the upper liquid outlet hose is closed and the lower liquid outlet hose is connected (d).

[0074] When the two liquid outlet hoses are in the upper liquid outlet hose conductive state and the lower liquid outlet hose closed state (c) or the upper liquid outlet hose closed state and the lower liquid outlet hose conductive state (d), and you want to adjust them to the upper liquid outlet hose closed state and the lower liquid outlet hose conductive state (d) or the upper liquid outlet hose conductive state and the lower liquid outlet hose closed state (c), you need to first restore the liquid outlet state of the two liquid outlet hoses to the two liquid outlet hoses fully closed state (b) and then make adjustments.

[0075] The liquid outlet device of this solution is installed after the liquid pump. When the liquid outlet assembly is fully closed, the liquid pump is turned off. At this time, although the liquid outlet hose is in a conductive state, no liquid passes through it, and the liquid outlet hose can be disassembled or installed. The liquid pump generally adopts a peristaltic pump.

[0076] The mounting mechanism 2 includes a mounting base 21 and a liquid outlet assembly mounting base 22 detachably disposed on the mounting base 21 .

[0077] The liquid outlet assembly mounting seat 22 is provided with liquid outlet assembly mounting areas 23 whose number matches the number of liquid outlet assemblies 1, and each liquid outlet assembly mounting area 23 is evenly distributed on the liquid outlet assembly mounting seat 22. The liquid outlet assembly 1 is placed in the liquid outlet assembly mounting area 23.

[0078] The adjustment component 32 is detachably mounted on the liquid outlet component mounting seat 22 and placed between the liquid outlet component mounting areas 23. The adjustment component works by moving closer to or away from the liquid outlet component, applying pressure to the liquid outlet component or relaxing the adjustment component, and synchronously adjusting all the liquid outlet components.

[0079] In one embodiment, Figure 1 and Figure 2 As shown, a mounting plate 211 is provided on the mounting base 21, and a liquid outlet assembly mounting seat 22 is fixedly mounted on the mounting plate 211. Two groups of liquid outlet assemblies are provided, and two groups of liquid outlet assembly mounting areas 23 are provided, which are symmetrically mounted on the liquid outlet assembly mounting seat 22. In order to achieve simultaneous adjustment and control of the two liquid outlet assemblies, the adjustment assembly is also installed on the liquid outlet assembly mounting seat 22 and is located between the two liquid outlet assemblies. When the adjustment assembly adjusts the liquid outlet assembly, the adjustment assembly applies a pressing force to the liquid outlet assembly or relaxes the liquid outlet assembly to adjust the liquid outlet state of the liquid outlet assembly.

[0080] In one embodiment, two groups of liquid outlet assemblies are provided based on the above-mentioned proposal, and the liquid outlet assemblies adopt liquid outlet hoses. The liquid outlet assembly installation area 23 is provided with installation grooves 24 for installing the liquid outlet assemblies. The number of the installation grooves is adapted to the number of the liquid outlet assemblies, and the liquid outlet assembly 1 is placed in the installation grooves 24. When the adjustment assembly adjusts the liquid outlet assembly, the adjustment assembly 32 presses or relaxes the liquid outlet assembly 1 along the depth direction of the installation groove 24. The depth and width of the installation groove are adapted to the liquid outlet hose, which is convenient for restricting the liquid outlet hose in the installation groove, and at the same time, it is convenient for the adjustment assembly to apply pressing force or relax the liquid outlet hose, so as to avoid interference between the adjustment assembly and the liquid outlet assembly mounting seat 22 when adjusting the liquid outlet state of the liquid outlet hose.

[0081] In one embodiment, to facilitate installation of the liquid outlet hose in the installation groove, the installation groove is parallel to the liquid outlet hose, and the installation groove passes through the liquid outlet assembly installation area 23, and both ends of the liquid outlet hose extend from both ends of the installation groove respectively.

[0082] When the two liquid outlet hoses are in the fully open state of the liquid outlet assembly, the adjustment assembly has no pressing force on the liquid outlet hoses. In order to facilitate the rapid removal of each liquid outlet hose from the mounting mechanism, the maximum distance between the adjustment assembly 32 and the mouth of the mounting groove 24 is adapted to the liquid outlet assembly 1, and the maximum distance between the adjustment assembly 32 and the mouth of the mounting groove 24 should be adapted to the outer diameter of the liquid outlet hose, or slightly smaller than the outer diameter of the liquid outlet hose, so that the liquid outlet hose can be squeezed from the mouth of the adjustment assembly 32 and the mounting groove 24 into the mounting groove or removed from the mounting groove, thereby realizing the rapid installation and removal of the liquid outlet hose. After the liquid outlet hose enters the mounting groove, when the liquid outlet hose is not subjected to the pressing force of the adjustment assembly, the liquid outlet hose rebounds, and the diameter of the liquid outlet hose is slightly larger than or adapted to the distance between the adjustment assembly 32 and the mouth of the mounting groove 24, and the liquid outlet hose itself will not actively detach from the mounting groove.

[0083] In one embodiment, Figure 1 and Figure 2 As shown, the adjustment component 32 includes a cam 321, and the liquid outlet component uses the cam to complete the adjustment operation. The outer circular surface of the cam 321 is an adjustment surface 3211, and the adjustment surface 3211 faces the liquid outlet component 1. When the cam 321 rotates, the adjustment surface 3211 presses or releases the liquid outlet component 1 to adjust the liquid outlet state of the liquid outlet component.

[0084] In this solution, by designing the radius and arc length of the cam's adjustment surface, the cam's adjustment surface 3211 presses or releases the liquid outlet component 1 when the cam rotates. Figure 5 As shown, based on the liquid outlet component 1, two groups are arranged, and the adjustment surface 3211 includes a first arc surface 01, a second arc surface 02, a third arc surface 03, a fourth arc surface 04, a fifth arc surface 05 and a plane 06 which are smoothly connected in sequence, and the plane 06 is connected to the first arc surface 01 away from the end of the fifth arc surface 05.

[0085] like Figure 3 As shown, when the plane 06 or the third curved surface 03 faces the liquid outlet component 1, the liquid outlet component 1 is completely relaxed. When the first curved surface 01 or the fifth curved surface 05 faces the liquid outlet component 1, the liquid outlet component 1 is safely squeezed and the liquid outlet component 1 is cut off. When the second curved surface 02 or the fourth curved surface 04 faces the liquid outlet component 1, the liquid outlet component 1 is squeezed but in a conductive state.

[0086] Based on the liquid outlet component 1, there are two groups, such as Figure 3 and Figure 5 As shown, the cam rotates and adjusts the liquid discharge state of the liquid discharge hose at the same time. The liquid discharge state includes the state where both liquid discharge hoses are fully open, the state where both liquid discharge hoses are fully closed, and the state where only one liquid discharge hose is open and the other liquid discharge hose is closed. That is:

[0087] The distance between the plane 06 on the adjustment surface of the cam and the center of the cam 321 is adapted to the radius of the third arc surface 03. The radius of the third arc surface 03 (such as Figure 3 The radius of the circle corresponding to the double-dotted line R2 is adapted to the distance between the center of the cam and the liquid outlet assembly.

[0088] The first arc surface 01 and the fifth arc surface 05 are arc surfaces of equal diameter and are symmetrically arranged. The radius of the first arc surface 01 and the fifth arc surface 05 are adapted to each other. The arc length of the first arc surface 01 and the fifth arc surface 05 are adapted to each other, and the arc length of the first arc surface 01 is close to 1 / 5 of the circumference of the outer circular surface of the cam. The radius of the first arc surface 01 is adapted to the distance between the center of the cam 321 and the liquid outlet component 1 in the fully pressed state, such as Figure 3 The radius of the circle corresponding to the double-dotted line R1.

[0089] The second arc surface 02 and the fourth arc surface 04 are both variable diameter arc surfaces and are symmetrically arranged. The arc lengths of the second arc surface 02 and the fourth arc surface 04 are adapted to each other, and the arc length of the second arc surface 02 is close to 1 / 5 of the circumference of the outer circular surface of the cam. The radius of the second arc surface 02 gradually decreases from the end close to the first arc surface 01 to the end close to the third arc surface 03, and the radius of the fourth arc surface 04 gradually increases from the end close to the third arc surface 03 to the end close to the fifth arc surface 05. The radius of the second arc surface 02 close to the first arc surface 01 is adapted to the radius of the first arc surface 01, and the radius of the second arc surface 02 close to the third arc surface 03 is adapted to the radius of the third arc surface 03.

[0090] The radius of the second arc surface 02 gradually decreases from the end close to the first arc surface 01 to the end of the third arc surface 03, and the radius of the fourth arc surface 04 gradually increases from the end close to the third arc surface 03 to the end of the fifth arc surface 05, so that the second arc surface and the fourth arc surface can linearly adjust the flow rate of the liquid outlet component when they are in contact with the liquid outlet component.

[0091] The first arc surface and the fourth arc surface are basically centrally symmetrically arranged and have the same arc length, and the second arc surface and the fifth arc surface are basically centrally symmetrically arranged and have the same arc length, ensuring that the cam controls the two liquid outlet hoses so that only one liquid outlet hose is open and the other liquid outlet hose is closed.

[0092] In one embodiment, Figure 3 As shown, the axis of the cam 321 is perpendicular to the liquid outlet hose 11. In another embodiment, the axis of the cam 321 is parallel to the liquid outlet hose 11. Figure 4 The two ways of setting the cam axis have the same effect on regulating the liquid discharge state of the liquid discharge hose. However, when the axis of the cam 321 is perpendicular to the liquid discharge hose 11, the wheel surface of the cam is parallel to the liquid discharge hose, which is conducive to reducing the volume of the liquid discharge device and making the liquid discharge device compact.

[0093] In this solution, the adjustment mechanism 3 also includes a driving mechanism 31 that drives the adjustment component 32 to move. The driving mechanism 31 is connected to a rotating shaft 312, and the rotating shaft 312 passes through a cam 321, driving the cam 321 to rotate, and the adjustment surface 3211 presses or releases the liquid outlet component 1. The driving mechanism 31 is started, driving the rotating shaft 312 to rotate, and the cam 321 fixed on the rotating shaft 312 rotates, and the position of the adjustment surface 3211 on the cam 321 changes, changing the pressure depth of the adjustment surface on the liquid outlet component, so as to adjust the liquid outlet state of the liquid outlet component.

[0094] like Figure 6 As shown, the driving mechanism drives the rotating shaft to rotate, and the cam fixed on the rotating shaft rotates to adjust the liquid outlet state of the liquid outlet assembly (two liquid outlet hoses). Figure 6 (a), the two liquid outlet hoses are fully open; the cam rotates to Figure 6 (b) The two liquid outlet hoses are fully closed; the cam rotates to Figure 6 (c), the upper liquid outlet hose is in the on state and the lower liquid outlet hose is in the off state; the cam rotates to Figure 6 (d) The upper liquid outlet hose is closed and the lower liquid outlet hose is connected.

[0095] The driving mechanism 31 can be any device in the prior art that can drive the shaft to rotate and meet the requirements of the shaft rotation angle accuracy, such as a steering gear 311 or a stepping motor or a servo motor.

[0096] In one embodiment, Figure 2 As shown, in order to facilitate the installation of the adjustment mechanism, a cam receiving groove 25 is provided on the liquid outlet assembly mounting seat 22, and the mounting groove for installing the liquid outlet hose is placed on the two side walls of the cam receiving groove 25. The rotating shaft 312 passes through the cam receiving groove, and the cam is fixedly sleeved on the rotating shaft and placed in the cam receiving groove, and the outer circumferential surface of the cam faces the mounting groove 25. A cam pressure cover 322 is provided outside the cam, and the cam pressure cover 322 and the cam receiving groove are detachably fixedly installed to protect the cam. A cam receiving area 3221 is provided on the cam pressure cover 322, and the cam is placed in the cam receiving area 3221 and is located between the liquid outlet assembly mounting seat 22 and the cam pressure cover 322. In order to ensure smooth rotation of the cam, a first bearing 313 and a second bearing 312 are sleeved on the rotating shaft, and the first bearing 313 and the second bearing 312 are respectively installed on the liquid outlet assembly mounting seat 22 and the cam pressure cover 322 to achieve the installation of the rotating shaft.

[0097] In the above embodiment, the cam cover 322 is provided to protect and limit the cam, thereby preventing the cam from being contaminated or impurities from adhering to the cam, which would affect the size of each arc surface on the adjustment surface of the cam, thereby ensuring that the adjustment surface of the cam can accurately adjust the liquid discharge state of the liquid outlet component, especially the liquid discharge flow rate.

[0098] In this solution, the end of the rotating shaft 312 away from the driving mechanism 31 passes through the center of the cam 321 and is fixedly connected to the status indicator disk 4, on which a flow indicator scale of the liquid outlet component is provided. The flow indicator scale of the liquid outlet component intuitively displays the liquid outlet state or liquid outlet flow size of the corresponding liquid outlet component. The status indicator disk 4 is fixed to the outer end of the rotating shaft. In one embodiment, the status indicator disk 4 is circular and parallel to the cam. The flow indicator scale of the liquid outlet component can be a colored indicator bar. The on and off of the liquid outlet component can be judged by the presence or absence of the indicator bar, and the size of the flow can be judged by the width of the indicator bar. In order to further obtain accurate flow values, the corresponding flow value can be marked on one side of the indicator bar, which is clear, intuitive and convenient to observe.

[0099] In one embodiment, the adjustment assembly 32 may also be a cam-connecting rod assembly. The cam-connecting rod assembly includes a connecting rod and a cam 321. The cam 321 drives the connecting rod to move. The cam 321 squeezes or loosens the liquid discharge hose 11 through the connecting rod, so that the liquid discharge hose 11 is in a closed or conductive state. With the help of the connecting rod, it is possible to effectively avoid the wear of the liquid discharge hose 11 when the liquid discharge hose 11 is switched between the open and closed states, thereby extending the service life of the liquid discharge hose 11. Specifically, the cam 321 squeezes or loosens the liquid discharge hose 11 through the output end of the connecting rod. The output end of the connecting rod is in an arc shape, and the area of ​​contact between the output end of the connecting rod and the liquid discharge hose 11 is not less than the diameter of the liquid discharge hose 11, ensuring that the output end of the connecting rod squeezes the liquid discharge hose 11 and can completely close it. In addition, the connecting rod in this embodiment can be a connecting rod or a connecting rod mechanism composed of multiple connecting rods. It only needs to ensure that when the cam 321 rotates, it can drive the output end of the connecting rod to squeeze or loosen the liquid discharge hose 11, so that the liquid discharge hose 11 is in a closed or conductive state. In this embodiment, there are two liquid outlet hoses 11, and correspondingly, there are two connecting rods. The cam 321 drives the two connecting rods to control the opening or closing of the two liquid outlet hoses 11 respectively, that is, the following opening and closing states of the two liquid outlet hoses 11 can be achieved: when the cam 321 rotates to Figure 6 (a), the two connecting rods loosen the two liquid outlet hoses 11 respectively, so that the two liquid outlet hoses 11 are in a fully open state; when the cam 321 rotates to Figure 6 (b), the two connecting rods squeeze the two liquid outlet hoses 11 respectively, so that the two liquid outlet hoses 11 are in a fully closed state; when the cam 321 rotates to Figure 6 (c), the upper connecting rod releases the upper liquid outlet hose 11, so that the upper liquid outlet hose 11 is in a conducting state, and the lower connecting rod squeezes the lower liquid outlet hose 11, so that the lower liquid outlet hose 11 is in a closed state; when the cam 321 rotates to Figure 6 (d), the upper connecting rod squeezes the upper liquid outlet hose 11, so that the upper liquid outlet hose 11 is in a closed state, and the lower connecting rod loosens the lower liquid outlet hose 11, so that the lower liquid outlet hose 11 is in a conducting state.
