Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides a technical solution:

[0025] A piezoelectric ceramic high-frequency jet dispensing valve includes a dispensing valve body 1, with a feeding tank 3 disposed on the right side of the dispensing valve body 1. The valve body 1 is characterized by a conveying mechanism 2 disposed between the dispensing valve body 1 and the feeding tank 3 for disassembling and cleaning the conveying pipe. The conveying mechanism 2 includes:

[0026] The disassembly and assembly unit 21 is located between the dispensing valve body 1 and the feeding tank 3. It includes a feed pipe 211 and a discharge pipe 212. Threaded rings 213 are fixedly installed on the surfaces of both the feed pipe 211 and the discharge pipe 212. A conveying pipe 215 is fixedly installed between the feed pipe 211 and the discharge pipe 212. Retaining rings 216 are slidably installed on both ends of the conveying pipe 215. Threaded sleeves 217 are rotatably installed on the surface of the retaining rings 216. The feed pipe 211, the discharge pipe 212, and the conveying pipe 215 are connected by threaded sleeves 217 threaded onto the surface of the threaded rings 213, thus facilitating the disassembly and assembly of the conveying pipe 215.

[0027] Heating unit 22 is disposed on the surface of conveying pipe 215 and is used to heat the inside of conveying pipe 215.

[0028] In this embodiment, the feed pipe 211 is fixedly installed at the bottom of the feed hopper 3, and the discharge pipe 212 is fixedly installed on the right side of the dispensing valve body 1.

[0029] The card block 2110 slides into the slot 214, connecting the conveying pipe 215 with the feed pipe 211 and the discharge pipe 212. The threaded sleeve 217 rotates and connects with the threaded ring 213 on the surface of the threaded ring 213, thereby enabling the quick disassembly of the conveying pipe 215. This facilitates the cleaning of residual adhesive inside the conveying pipe 215, preventing long-term accumulation that could lead to blockage and affect the dispensing effect.

[0030] In this embodiment, slots 214 are provided at the opposite ends of the feed pipe 211 and the discharge pipe 212, and blocks 2110 are fixedly installed at both ends of the conveying pipe 215, and the blocks 2110 slide into the inside of the slots 214.

[0031] The card block 2110 slides into the inside of the card slot 214, thereby limiting the position of the conveying pipe 215 and facilitating the alignment of the conveying pipe 215 with the feed pipe 211 and the discharge pipe 212.

[0032] In this embodiment, the retaining ring 216 is slidably inserted into the inner groove of the threaded ring 213 and covers the surface of the locking block 2110. When the retaining ring 216 is slidably inserted into the inner groove of the threaded ring 213, the retaining ring 216 covers the surface of 21110 to prevent the adhesive from flowing out from the connection between the locking block 2110 and the slot 214.

[0033] In this embodiment, a sliding groove 218 is provided inside the retaining ring 216, and a set of limiting blocks 219 are fixedly installed on both ends of the conveying pipe 215, and the limiting blocks 219 are located inside the sliding groove 218 to adapt to sliding.

[0034] When the retaining ring 216 is slidably inserted into the inner groove of the threaded ring 213, the limiting block 219 is located inside the slide groove 218 to adapt to the sliding, thereby preventing the retaining ring 216 from rotating with the threaded sleeve 217 and realizing the limitation of the movement of the retaining ring 216.

[0035] In this embodiment, the heating unit 22 includes a housing 221 fixedly installed on the surface of the conveying pipe 215. A heating wire 222 is fixedly installed between the housing 221 and the conveying pipe 215, and a heater 223 is fixedly installed on the surface of the heating wire 222. One end of the heating wire 222 passes through the housing 221 and is fixedly connected to the heater 223.

[0036] The heater 223 is model LTS-064. When the heater 223 operates, it heats the heating wire 222. The heating wire 222 heats the cavity between the outer shell 221 and the delivery pipe 215, thereby heating the inside of the delivery pipe 215 and preventing the colloid from solidifying when the flow rate inside the delivery pipe 215 is not fast.

[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0038] During operation, firstly, the locking block 2110 slides into the slot 214 to connect the conveying pipe 215 with the feed pipe 211 and the discharge pipe 212. Then, the threaded sleeve 217 rotates and connects with the threaded ring 213 on the surface of the threaded ring 213. When the threaded sleeve 217 is connected with the threaded ring 213, the limiting block 219 slides inside the slide groove 218, and the retaining ring 216 slides into the inner groove of the threaded ring 213, thus completing the installation of the conveying pipe 215.

[0039] Then, the colloid inside the feeding hopper 3 enters the dispensing valve body 1 through the conveying mechanism 2. When the colloid flows inside the conveying mechanism 2, the heater 223 operates to heat the heating wire 222. The heating wire 222 heats the cavity between the outer shell 221 and the conveying pipe 215, and heats the inside of the conveying pipe 215.
