Description

Technical Field

[0001] This utility model relates to the field of dental equipment technology, and specifically to an integrated valve connector snap-fit ​​structure applied to dental equipment. Background Technology

[0002] An integrated valve, also known as a triple diaphragm valve, is a type of valve that uses the elastic deformation of a diaphragm to control the flow of fluid. It is commonly found in dental equipment.

[0003] Reference Figure 12 The integrated valve shown (triple diaphragm valve) includes a valve body 1, a diaphragm 2, and a valve cover 3 connected sequentially from bottom to top. The valve body 1 has a medium channel and a control port. The valve body 1 usually has a connector, the main function of which is to connect a conduit, thereby establishing a fluid channel between the integrated valve and an external fluid supply system or actuator, ensuring that the fluid can be delivered stably and accurately according to the diagnostic and treatment requirements. During the installation of the connector, the operator needs to first install the connector on the valve body by rotating the thread. After completing the threaded installation of the connector and the valve body, the conduit needs to be fitted onto the insertion part of the connector. However, in actual integrated valves, the connectors are often densely distributed, and the space between adjacent connectors is limited. This dense layout makes it difficult to accurately find the appropriate operating angle and space for the conduit during the fitting process, resulting in increased installation difficulty and slow installation efficiency. Moreover, installing the conduit in a narrow space can easily damage the conduit or connector due to improper operation, further increasing the maintenance cost of the integrated valve and the risk of installation failure. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides an integrated valve connector snap-fit ​​structure for use in dental equipment.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An integrated valve connector snap-fit ​​structure for dental equipment includes a valve body, a diaphragm, and a valve cover connected sequentially from bottom to top. The valve body has a media channel and a control hole. The media channel includes an input channel and at least one branch channel. The branch channel includes a media delivery hole and a media transmission hole whose lower end communicates with the input channel. The lower ends of the control hole and the media delivery hole are both provided with bottom connection holes penetrating the bottom surface of the valve body. The valve cover has a control channel, which includes a release groove communicating with the control hole. Each release groove corresponds to a branch channel. The key feature is that a bottom connector is inserted into each bottom connection hole. The insertion end of the bottom connector has a main snap-fit ​​groove. A main snap-fit ​​piece is slidably installed on the bottom of the valve body and can slide into the main snap-fit ​​groove to fix the bottom connector to the valve body.

[0007] In this utility model, the main card plate is provided with the same number of main card holes as the bottom connector. The main card holes include a main through hole and a main buckle hole that are connected sequentially along the sliding direction of the main card plate. The insertion end of the bottom connector partially passes through the main through hole and is inserted into the bottom connector hole. When the main card plate is slid to move the main buckle hole to the insertion end position of the bottom connector, the part of the main card plate corresponding to the outer peripheral edge of the main buckle hole is engaged in the main card slot.

[0008] In this utility model, a main insertion slot is provided on the bottom of the valve body, and one end of the main clip is provided with a main clip insertion part that can be inserted into the main insertion slot when the main clip hole moves to the bottom connector insertion end position.

[0009] In this utility model, the bottom of the valve body is provided with two opposing main limiting parts, and a main guiding groove is formed between the two main limiting parts. The other end of the main clamping piece is provided with a main guiding part that slides in the main guiding groove.

[0010] In this utility model, the valve body is provided with a card mounting screw hole, and the main card mounting plate is provided with a card sliding elongated hole corresponding to the card mounting screw hole. The length direction of the card sliding elongated hole is parallel to the sliding direction of the main card mounting plate, and a card mounting bolt with a screw end threaded in the card mounting screw hole is inserted through the card sliding elongated hole.

[0011] In this utility model, the valve body is provided with a side connection hole on the left side and / or the right side. Each input channel is connected to a side connection hole at its left end and / or the right end. Each side connection hole is equipped with a mating part, which is a plug or a side connection head. The insertion end of the mating part is provided with a mating groove. A side retaining piece is slidably installed on the left side and / or the right side of the valve body and can be slidably inserted into the mating groove to fix the mating part on the valve body.

[0012] In this utility model, the side retaining piece is provided with the same number of side retaining holes as the mating parts. The upper end of the side retaining hole is open. The insertion end of the mating part is inserted into the side connecting hole. When the side retaining piece is slid to move the side retaining hole to the insertion end position of the mating part, the part of the side retaining piece corresponding to the outer peripheral edge of the side retaining hole is engaged in the mating groove.

[0013] In this utility model, the valve body has two oppositely arranged side mounting portions on the left and / or right sides, each side mounting portion having a side sliding slot, and the side retaining piece located between the two side mounting portions, with both ends of the side retaining piece being slidably inserted into the side sliding slots; the left or right end of the main retaining piece abuts against the bottom of the side retaining piece.

[0014] In this utility model, the bottom left end and / or right end of the valve cover is provided with a cover mounting portion for restricting the upward movement of the side clamping piece.

[0015] In this utility model, the cover mounting portion is provided with a top slot for inserting the upper end of the side mounting piece.

[0016] The beneficial effects of this utility model are as follows: By using the main clamping plate to clamp the bottom connector and the side clamping plate to clamp the mating parts, not only can the quick installation of components such as the bottom connector, side connector, and sealing head be achieved, improving the installation efficiency of the integrated valve, but also the bottom connector, side connector, and sealing head can be installed on the valve body without using threaded connections. Therefore, the conduit can be installed on the bottom connector and side connector first, and then the bottom connector and side connector can be installed on the valve body using the clamping method, thus avoiding the operational difficulties of installing the conduit on the connector in a narrow space and reducing the difficulty of conduit installation.

[0031] It should be noted that if any directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0032] Reference Figure 1-11 An integrated valve connector snap-fit ​​structure for dental equipment includes a valve body 1, a diaphragm 2, and a valve cover 3 connected sequentially from bottom to top. The valve body 1 has a medium channel and a control hole 101. The medium channel includes an input channel 102 and three branch channels distributed from left to right. In other embodiments, there may be only one branch channel. The branch channel includes a medium delivery hole 103 and a medium transmission hole 104 whose lower end communicates with the input channel 102. The lower end of the control hole 101 and the lower end of the medium delivery hole 103 are both provided with a bottom connection hole 105 penetrating the bottom surface of the valve body 1. The valve cover 3 has a control channel, each control channel corresponding to a control hole 101. The control channel includes a release groove 301 communicating with the control hole 101, and each release groove 301 corresponds to a branch channel.

[0033] Furthermore, a bottom connector 4 is inserted into each bottom connection hole 105. The insertion end of the bottom connector 4 is provided with a main locking groove 41. The bottom of the valve body 1 is slidably mounted with a main locking piece 6 that can slide into the main locking groove 41 to fix the bottom connector 4 on the valve body 1. The main locking piece 6 is provided with the same number of main locking holes as the bottom connector 4. The main locking holes include a main through hole 61 and a main snap hole 62 that are sequentially connected along the sliding direction of the main locking piece 6. The insertion end of the bottom connector 4 partially passes through the main through hole 61 and is inserted into the bottom connection hole 105. When the main locking piece 6 is slid to move the main snap hole 62 to the insertion end position of the bottom connector 4, the part of the main locking piece 6 corresponding to the outer peripheral edge of the main snap hole 62 is locked into the main locking groove 41. In addition, the insertion end of the bottom connector 4 is provided with a bottom mounting groove located above the main snap-fit ​​groove 41, and a bottom sealing ring 40 is installed in the bottom mounting groove for contacting and sealing with the hole wall of the bottom connector hole 105.

[0034] In this embodiment, the bottom of the valve body 1 is provided with a main insertion slot 11, and one end of the main clip 6 is provided with a main clip insertion part 63 that can be inserted into the main insertion slot 11 when the main buckle hole 62 moves to the insertion end position of the bottom connector 4, thereby improving the installation quality of the main clip 6.

[0035] In this embodiment, the bottom of the valve body 1 is provided with two opposing main limiting parts 12, and a main guiding groove is formed between the two main limiting parts 12. The other end of the main clamping piece 6 is provided with a main guiding part 64 that slides in the main guiding groove, thereby improving the sliding positioning quality of the main clamping piece 6.

[0036] In this embodiment, the valve body 1 is provided with a card mounting screw hole 13, and the main card mounting piece 6 is provided with a card sliding elongated hole 65 corresponding to the card mounting screw hole 13. The length direction of the card sliding elongated hole 65 is parallel to the sliding direction of the main card mounting piece 6. A card mounting bolt with a screw end threaded into the card mounting screw hole 13 is inserted into the card sliding elongated hole 65. Tightening the card mounting bolt can fix the main card mounting piece 6 immovably on the valve body 1, and loosening the card mounting bolt can allow the main card mounting piece 6 to slide. The card mounting bolt is not shown in the accompanying drawings.

[0037] To facilitate the connection of various conduits to each input channel 102, the valve body 1 is provided with side connection holes 108 on the left and / or right sides. Each input channel 102 is connected to a side connection hole 108 at its left and / or right ends. Each side connection hole 108 is fitted with a mating component, which is a plug head 51 or a side connection head 52. The insertion end of the mating component is provided with a mating groove. Side retaining pieces 7 are slidably installed on the left and / or right sides of the valve body 1, which can slide into the mating groove to fix the mating component on the valve body 1. The side retaining pieces 7 are provided with the same number of side retaining holes 71 as the mating components. The upper end of the side retaining holes 71 is open. The insertion end of the mating component is inserted into the side connection hole 108. When the side retaining piece 7 is slid to move the side retaining hole 71 to the insertion end position of the mating component, the part of the side retaining piece 7 corresponding to the outer peripheral edge of the side retaining hole 71 is engaged in the mating groove, thereby realizing the retaining and fixing of the mating component.

[0038] In this embodiment, for ease of processing, both ends of the input channel 102 are connected to a side connection hole 108. The fitting installed on the left side connection hole 108 is a sealing head 51 that blocks the left end of the input channel 102, and the fitting installed on the right side connection hole 108 is a side connection head. This side connection head is used to connect a conduit, allowing gas or liquid to flow into the input channel 102. Furthermore, the insertion end of the fitting is provided with a side mounting groove, in which a side sealing ring 70 is installed for contacting and sealing with the wall of the side connection hole 108.

[0039] In this embodiment, the valve body 1 has two oppositely arranged side mounting portions 14 on its left and / or right sides. The side mounting portions 14 are provided with side sliding slots. The side retaining piece 7 is located between the two side mounting portions 14. The two ends of the side retaining piece 7 are slidably inserted into the side sliding slots, thereby improving the installation quality of the side retaining piece 7.

[0040] In this embodiment, the left or right end of the main card holder 6 presses against the bottom of the side card holder 7, preventing the side card holder 7 from sliding down arbitrarily, thereby using the main card holder 6 to install the side card holder 7.

[0041] In this embodiment, the bottom left end and / or right end of the valve cover 3 is provided with a cover mounting part 31 for restricting the upward movement of the side retaining piece 7, so that the side retaining piece 7 is located within the enclosure of the main retaining piece 6, the cover mounting part 31 and the two side mounting parts 14, thereby realizing the positioning and installation of the side retaining piece 7; in addition, in order to improve the installation quality of the side retaining piece 7, the cover mounting part 31 is provided with a top slot 32 for the upper end of the side retaining piece 7 to be inserted, thereby restricting the upward movement of the side retaining piece 7.

[0042] By using the main clamping plate 6 to clamp the bottom connector 4 and the side clamping plate 7 to clamp the mating parts, not only can the quick installation of components such as the bottom connector 4, the side connector 52, and the plug 51 be achieved, improving the installation efficiency of the integrated valve, but also the bottom connector 4, the side connector 52, and the plug 51 do not need to be installed on the valve body 1 by threaded connection. Therefore, the conduit can be installed on the bottom connector 4 and the side connector 52 first, and then the bottom connector 4 and the side connector 52 can be installed on the valve body 1 by clamping. This avoids the operational difficulties of installing the conduit on the connector in a narrow space and reduces the difficulty of conduit installation.

[0043] In this embodiment, the branch channel further includes an anti-wrinkle groove 106 on the top surface of the valve body 1. The anti-wrinkle groove 106 is a concave arc surface recessed downward on the top surface of the valve body 1. The deformed part of the diaphragm 2 can fit into the groove surface of the anti-wrinkle groove 106, thus reducing the probability of wrinkles. The upper ends of the medium transmission hole 104 and the medium delivery hole 103 both penetrate the groove surface of the anti-wrinkle groove 106. The top view cross-section of the upper and lower corresponding anti-wrinkle grooves 106 is adapted to the top view cross-section of the release groove 301. The top view cross-sections of the release groove 301 and the anti-wrinkle groove 106 are circular or oblong, preferably oblong, with a large area, which facilitates the part of the diaphragm 2 to be recessed into the anti-wrinkle groove 106.

[0044] In this embodiment, an anti-wrinkle groove 106 is provided on the top surface of the valve body 1, so that the deformed part of the diaphragm 2 can fit into the groove surface of the anti-wrinkle groove 106, thereby reducing the probability of the diaphragm 2 forming wrinkles during the sealing process, avoiding material fatigue and local perforation caused by wrinkles, effectively extending the service life of the diaphragm 2, and thus reducing the overall maintenance cost of the integrated valve.

[0045] A bottom connector 4 is installed in the bottom connection hole 105 at the lower end of the control hole 101. This bottom connector 4 is connected to the gas source through a conduit and a control valve. Under normal conditions, the high-pressure gas output from the gas source is input into the release groove 301 through the control hole 101. This high-pressure gas acts on the diaphragm 2, causing the diaphragm 2 to adhere to the groove surface of the anti-wrinkle groove 106, thereby sealing the upper ends of the medium transmission hole 104 and the medium delivery hole 103, thus disconnecting the medium transmission hole 104 and the medium delivery hole 103. When the control valve depressurizes, the high-pressure gas in the release groove 301 is released, allowing the diaphragm 2 to be pushed open by the medium flowing in from the input channel 102 and recessed into the release groove 301, at which point the medium transmission hole 104 and the medium delivery hole 103 are connected.

[0046] In this embodiment, the valve cover 3 is provided with a connecting through hole 304, and the valve body 1 is provided with a corresponding connecting screw hole 107. A connecting bolt threaded into the connecting screw hole 107 passes through the connecting through hole 304, thereby connecting the valve cover 3 and the valve body 1 together. Additionally, the diaphragm 2 is provided with a connecting clearance hole 202 to avoid interference with the connecting bolt. The connecting bolt is not shown in the accompanying drawings.

[0047] In this embodiment, there are three media channels: a power gas channel for supplying power gas to the mobile phone, a liquid channel for supplying liquid to the mobile phone, and a cleaning gas channel for supplying cleaning gas to the mobile phone. The power gas channel's input channel 102 is located on the top surface of the valve body 1. The upper end of this input channel 102 is sealed by a diaphragm 2, and the lower end communicates with the corresponding side connection hole 108 through a power gas flow hole 1021. The liquid channel and the cleaning gas channel are located between the top and bottom surfaces of the valve body 1.

[0048] In this embodiment, each control channel has three release slots 301 that are interconnected. The three interconnected release slots 301 are a first release slot 3011, a second release slot 3012, and a third release slot 3013. The first release slot 3011 corresponds to a branch channel of the power gas channel, the second release slot 3012 corresponds to a branch channel of the liquid channel, and the third release slot 3013 corresponds to a branch channel of the clean gas channel. The purpose of one control for three channels can be achieved through the three release slots 301 of the control channel.

[0049] In this embodiment, the control channel includes a gas distribution structure, which includes a gas distribution groove 302 located at the bottom of the valve cover 3 and two gas distribution holes 303 located at the top of the valve cover 3 and communicating with the gas distribution groove 302. The diaphragm 2 is provided with control clearance holes 201 corresponding to the control hole 101 and the gas distribution groove 302, so that the control hole 101 and the gas distribution groove 302 are connected through the control clearance holes 201. The end of the gas distribution hole 303 away from the gas distribution groove 302 is sealed with a gas distribution plug. The walls of the three release grooves 301 of the control channel are provided with connecting air holes 3010 communicating with the gas distribution holes 303, so that the three release grooves 301 of the control channel are interconnected. The gas distribution plug is not shown in the figures.

[0050] In this embodiment, the valve body 1 is provided with a connecting air passage 109, and one or both ends of the connecting air passage 109 are connected to a side connecting hole 108; the connecting air passage 109 is connected to the anti-wrinkle groove 106 of the power air passage through a connecting air hole 110, and the connecting air passage 109 is connected to a pressure regulating hole 1091, and a pressure regulating valve 8 is installed in the pressure regulating hole 1091. The above is the prior art. Using the pressure regulating valve 8 to regulate the air pressure is the prior art, so it will not be described in detail.

[0051] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
