Description

Technical Field

[0001] This utility model belongs to the field of faucet technology and relates to an electronic faucet. Background Technology

[0002] The draft beer machine mainly consists of several components, including the beer tap, beer spear, dispenser, and beer keg. The dispenser and beer spear draw the beer from the keg to the beer tap, which acts as an on / off switch.

[0003] Existing wine dispensing nozzles, such as the automatic wine dispenser disclosed in Chinese patent literature [Patent No.: 202411114152.4; Application Publication No.: CN118728988A], include an electric drive component, a valve body with a wine dispensing hole, and an operating component that is connected to the electric drive component. The valve body is provided with a valve core, which is made of rubber material and includes an annular connecting part. The inner circumferential surface of the connecting part has a block-shaped sealing part extending towards the center of the connecting part. A clearance gap is formed between the sealing part and the connecting part. The connecting part is fixed in the inner cavity of the valve body. The inner end of the operating component is plate-shaped and passes through the connecting part and is inserted into the sealing part.

[0004] This type of dispensing device uses an electric drive shaft to drive an operating component, which in turn opens and closes the dispensing orifice. However, in this type of dispensing device, the upper part of the first half-valve body is U-shaped and is fixed to one end of the electric drive component. The drive shaft is horizontally positioned and passes through the upper part of the first half-valve body. The operating component is vertically positioned, and the connector on the drive shaft engages with the bayonet on the operating component. This integrates the electric drive component, valve body, and housing into one unit. When the valve body needs to be removed for cleaning, the housing and the electric drive component must be disassembled, making valve body disassembly and cleaning inconvenient. Summary of the Invention

[0005] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing an electronic faucet. The technical problem solved is how to ensure the compact structure of the electronic faucet while making the valve body easy to disassemble and clean.

[0006] The objective of this utility model can be achieved through the following technical solution: An electronic faucet includes a housing integrated with electronic components, a valve body having an inlet and an outlet, and an electromagnetic valve disposed within the housing. The electromagnetic valve is characterized in that it includes a fixed rod and a slidable plunger valve core passing through the fixed rod. An elastic element is provided between the fixed rod and the plunger valve core. The bottom of the fixed rod is detachably fixed to the valve body, and the top of the fixed rod is detachably fixed to the housing, pulling and fixing the valve body outside the housing. Under the elastic force of the elastic element, the plunger valve core can cut off the connection between the inlet and the outlet. The electromagnetic valve can overcome the elastic force of the elastic element to drive the plunger valve core to move, connecting the inlet and the outlet.

[0007] The plunger valve core, under the elastic force of the elastic element, cuts off the connection between the inlet and outlet, keeping the electronic faucet in the closed state. In use, activating the solenoid valve causes the plunger valve core to move against the elastic force of the elastic element, connecting the inlet and outlet, thus opening the electronic faucet. During assembly, the bottom of the fixing rod is detachably fixed to the valve body, and then the top of the fixing rod passes through the housing and is detachably fixed to the housing, thereby tightening and fixing the valve body outside the housing, ensuring a compact structure for the electronic faucet. For disassembly, simply separate the top of the fixing rod from the housing to allow the valve body to detach, then remove the fixing rod for cleaning, making valve body disassembly and cleaning convenient. Electronic components are integrated within the housing and connected to it, avoiding interference during valve body disassembly and cleaning.

[0008] In one type of electronic faucet described above, the solenoid valve further includes a coil with a cylindrical through-hole. The top of the fixing rod passes through the through-hole and is detachably fixed to the housing. With this structure, simply separating the top of the fixing rod from the housing allows it to detach from the through-hole under its own weight, automatically disassembling the fixing rod and valve body, thus facilitating easy disassembly and cleaning of the valve body.

[0009] In one type of electronic faucet described above, the top of the housing has a through-hole for fixing, and the outer side wall of the bottom of the fixing rod has an annular abutment surface. The top of the fixing rod passes through the fixing hole and is detachably fixed to the housing by fasteners. The abutment surface abuts against the coil. This structure, through the abutment surface and fasteners, axially positions the fixing rod, thereby tightening and fixing the valve body outside the housing. This ensures a compact electronic faucet structure while facilitating easy disassembly and cleaning of the valve body. The fasteners can be nuts or open retaining rings.

[0010] In the aforementioned electronic faucet, the inner wall of the fixing hole has an annular stepped surface. The fastener is embedded in the fixing hole and is threadedly connected to the top of the fixing rod, abutting against the stepped surface. This structure facilitates the assembly and disassembly of the fastener and the fixing rod, thereby making the valve body easy to disassemble and clean. The fastener abutting against the stepped surface tightens and fixes the valve body to the outside of the housing, preventing the fixing rod and valve body from falling off after fixation.

[0011] In one of the aforementioned electronic faucets, the outer surface of the fastener is flush with the outer wall of the housing. This structure makes the exterior of the electronic faucet smooth.

[0012] In the aforementioned electronic faucet, the bottom of the fixed rod has a receiving hole, and the bottom of the plunger valve core has an annular groove. The elastic element is located in the receiving hole and the annular groove. The elastic element is a circular spring or a conical spring. The smaller diameter end of the elastic element acts on the groove wall at the bottom of the annular groove, and the larger diameter end of the elastic element acts on the fixed rod. This structure provides installation space for the elastic element through the receiving hole and the annular groove, and ensures that the smaller diameter end of the elastic element abuts against the groove wall at the bottom of the annular groove, preventing the elastic element from falling off the bottom of the plunger valve core. The arrangement is reasonable.

[0013] In the aforementioned electronic faucet, the fixed rod has a guide blind hole. The top of the guide blind hole is located in the middle or at the top of the fixed rod, and the bottom of the guide blind hole communicates with the receiving hole. The diameter of the receiving hole is larger than the diameter of the guide blind hole. The plunger valve core is slidably inserted through the receiving hole and the guide blind hole. In this structure, the guide blind hole guides the movement of the plunger valve core, causing it to move in a set direction. The larger diameter of the receiving hole provides sufficient installation space for the elastic element, allowing it to act on the plunger valve core.

[0014] In the aforementioned electronic faucet, the valve body has a valve hole that communicates with both the inlet and the outlet. The bottom of the fixing rod and the bottom of the plunger valve core are both embedded in the valve hole, and the bottom of the fixing rod is threadedly connected to the wall of the valve hole. This structure facilitates the connection between the fixing rod and the valve body, and allows for easy cleaning of the valve body after the fixing rod is removed.

[0015] In one of the aforementioned electronic faucets, the bottom of the housing has a clearance notch, and the valve body is embedded in the clearance notch. This structure results in a compact design after the housing and valve body are positioned.

[0016] In the aforementioned electronic faucet, the outer wall of the housing has a protruding guide portion located within the clearance notch, and the outer wall of the valve body has a recessed guide groove. The guide portion can move relative to the valve body along the guide groove, and is embedded in the guide groove to circumferentially position the housing and the valve body. In this structure, the guide portion and guide groove guide and limit the position of the valve body, allowing the valve body to be precisely embedded in the clearance notch. Furthermore, the interlocking concave-convex structure of the guide portion and guide groove ensures circumferential positioning of the housing and valve body, preventing the fixing rod from loosening after installation.

[0017] In the aforementioned electronic faucet, the outlet is a straight channel, and a wine dispensing tube is movably installed within the outlet, with the dispensing end of the tube located outside the outlet. The dispensing tube is retractable, and its length can be controlled according to actual needs, facilitating the operator in collecting the wine.

[0018] Compared with the prior art, the electronic faucet provided by this utility model has the following advantages:

[0019] 1. The bottom of the fixing rod of this electronic faucet is detachably fixed to the valve body, and the top of the fixing rod is detachably fixed to the housing, thereby tightening and fixing the valve body in the clearance notch outside the housing, ensuring the compact structure of the electronic faucet.

[0020] 2. When disassembling this electronic faucet, simply unscrew the fasteners to allow the fixing rod and valve body to automatically detach from the housing, making the valve body easy to disassemble and clean. Attached Figure Description

The plunger valve core 32 is slidably inserted into the receiving hole 312 and the guide blind hole 313. In this embodiment, the top of the guide blind hole 313 is located in the middle of the fixed rod 31. In actual production, the top of the guide blind hole 313 is located at the top of the fixed rod 31.

[0032] like Figure 4 As shown, the diameter of the receiving hole 312 is larger than the diameter of the guide blind hole 313. The bottom of the plunger valve core 32 has an annular groove 321. The elastic element 4 is located in the receiving hole 312 and the annular groove 321. The smaller diameter end of the elastic element 4 acts on the groove wall at the bottom of the annular groove 321, and the larger diameter end of the elastic element 4 acts on the fixing rod 31. In this embodiment, the elastic element 4 is a conical spring. In actual production, the elastic element 4 can be a cylindrical spring.

[0033] like Figure 3As shown, the top of the housing 1 has a through fixing hole 11, and the inner wall of the fixing hole 11 has an annular stepped surface 111. The coil 33 has a cylindrical through hole 331, and the outer wall of the bottom of the fixing rod 31 has an annular abutment surface 311. The top of the fixing rod 31 passes through the through hole 331 and is inserted into the fixing hole 11, and is then detachably fixed to the housing 1 by a fastener 5. The fastener 5 is threadedly fixed to the top of the fixing rod 31, the abutment surface 311 abuts against the coil 33, the fastener 5 is embedded in the fixing hole 11, and the fastener 5 abuts against the stepped surface 111. The outer surface of the fastener 5 is flush with the outer wall of the housing 1. In this embodiment, the fastener 5 is a nut; in actual production, the fastener 5 is an open retaining ring. When the fastener 5 is not locked, the fixing rod 31 can fall out of the through hole 331 under its own weight.

[0034] like Figure 7 As shown, the bottom of the housing 1 has a clearance notch 12, and the outer side wall of the housing 1 has a protruding guide portion 13, which is located in the clearance notch 12.
