Description

Technical Field

[0001] The utility model relates to the field of water heaters, in particular to a water inlet nozzle packaging structure of a ceramic heating tube. Background Art

[0002] With the rapid development of science, ceramic heating technology is increasingly being applied to heating systems. Due to the limitations of the manufacturing process of ceramic heating tubes, ceramic heating tubes are generally made into cylindrical or sheet structures. The heating part of the cylindrical ceramic tube is rolled onto the base material of the ceramic heating tube, and there will be a gap between the head and the tail of the heating part. Figure 1 As shown, when the ceramic heating body A1 is applied to the heating system, the general practice is to put a flange A2 on the ceramic heating body A1, and there is a certain gap between the flange A2 and the inner side of the ceramic heating body A1, fill the gap with structural glue, and then put it into the oven for baking, so that the glue can be cured to seal and withstand the locking force of the seal. This process is complicated and limited by the fluidity of the glue, resulting in leakage and poor sealing when the ceramic heating tube is applied to the heating system and connected to the heating cavity of the heating system. At the same time, the water inlet of the ceramic heating body A1 needs to be covered with a sealing body A5, and then connected to the water inlet cover A6 of the heating system; the power cord A3 on the ceramic heating body A1 is led out from one side of the water inlet cover A6. Since the lead welding point A4 of the power cord A3 and the ceramic heating body A1 is generally distributed at 120°, it also brings certain difficulties to the lead-out of the power cord A3. This connection method is costly, complex, and prone to water leakage when used, and the ceramic heating tube is easy to detach from the flange when the flange is subjected to a certain pressure.

[0003] Based on the above-mentioned defects of the water inlet connection structure of the traditional ceramic heating tube and the safety risks caused by leakage, it is necessary to improve the water inlet structure of the existing ceramic heating tube. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art such as poor sealing, easy water leakage and complex sealing structure of the water inlet end of the ceramic heating tube, and to provide a water inlet nozzle packaging structure of the ceramic heating tube.

[0032] The purpose of the utility model is to overcome the shortcomings of the prior art such as poor sealing, easy water leakage and complex sealing structure of the water inlet end of the ceramic heating tube, and to provide a water inlet nozzle packaging structure of the ceramic heating tube. The technical scheme of the utility model is adopted, a nozzle lining is arranged at the water inlet end of the ceramic heating tube, and a water inlet head is formed on the water inlet end of the ceramic heating tube and the outer side of the nozzle lining through an integrated injection molding process, and the water inlet end of the ceramic heating tube and the nozzle lining are coated together to form an integral structure, which has the advantages of high integration, compact structure, strict waterproof sealing, convenient production and low cost.

[0033] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0034] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Combination Figures 2 to 5As shown, a water inlet faucet packaging structure of a ceramic heating tube of the present embodiment comprises a ceramic heating tube 1, the water inlet end of the ceramic heating tube 1 is provided with a faucet lining 2 and a water inlet head 3, the ceramic heating tube 1 is a hollow cylindrical structure, the faucet lining 2 is provided with a connected water inlet joint 2-1 and a heating tube joint 2-2, the directions of the water inlet joint 2-1 and the heating tube joint 2-2 can be vertical, and of course can also be any required angle, the heating tube joint 2-2 is connected to the water inlet of the ceramic heating tube 1, the water inlet head 3 is integrally injection molded on the water inlet end of the ceramic heating tube 1 and the outer side of the faucet lining 2, the water inlet end of the ceramic heating tube 1 and the faucet lining 2 are covered together to form an integral structure, and the water inlet head 3 has a water inlet joint 3-1 connected to the water inlet joint 2-1 of the faucet lining 2. By using the injection molding and encapsulation process of the water inlet seal 3 at the water inlet end, the water inlet seal of the ceramic heating tube 1 is more reliably sealed, and the water inlet seal 3 is firmly connected with the ceramic heating tube 1 and the faucet lining 2. Compared with the traditional sealing structure during assembly, it has the advantages of high integration, compact structure, tight waterproof sealing, convenient manufacturing, and low cost.

[0036] Figure 3 and Figure 5 The internal structure of the water inlet faucet of the ceramic heating tube is shown. Among them, the faucet lining 2 plays the role of establishing the faucet channel, reducing the difficulty of injection molding of the water inlet head 3; the water inlet head 3 plays the role of covering and sealing, filling the matching gap, so that the water inlet faucet of the ceramic heating tube is reliably sealed and not easy to leak. The faucet lining 2 can be an injection molded part, which is assembled on the water inlet end of the ceramic heating tube 1 as an insert and secondary injection molded with the water inlet head 3. The ceramic production process of the ceramic heating tube 1, the injection molding structure design of the faucet lining 2 and the secondary injection molding and encapsulation process of the water inlet head 3 are combined to realize the packaging of the water inlet faucet of the ceramic heating tube.

[0037] Reference Figure 3 and Figure 5 As shown, in this embodiment, the outer diameter of the heating tube joint 2-2 is equivalent to the inner diameter of the water inlet of the ceramic heating tube 1, and the heating tube joint 2-2 is inserted into the water inlet of the ceramic heating tube 1, which is simple and convenient to assemble, and the water inlet end of the heating tube has good sealing performance, which solves the problem of easy water leakage in the existing assembly structure and is safer to use. The assembly gap between the faucet liner 2 and the ceramic heating tube 1 can be further filled and sealed by the water inlet head 3.

[0038] like Figure 6 and Figure 7As shown, in this embodiment, the side of the faucet lining 2 has a hollow area 2-5, and the lead welding point 1-2 of the ceramic heating tube 1 is opposite to the hollow area 2-5. The lead welding point 1-2 is respectively connected to the power line 1-1, and the power line 1-1 passes through the water inlet head 3, which facilitates the welding of the power line 1-1 on the ceramic heating tube 1. At the same time, the lead welding point 1-2 of the ceramic heating tube 1 can be sealed by the injection-molded water inlet head 3, effectively eliminating safety hazards such as leakage. Figure 8 and Fig. 9 As shown, there are three hollow areas 2-5 evenly distributed on the side of the faucet lining 2, each of which is opposite to a lead welding point 1-2, and there is a connecting column 2-4 between adjacent hollow areas 2-5. The inner side of the connecting column 2-4 has an envelope cylindrical surface with a diameter equivalent to the outer wall of the water inlet of the ceramic heating tube 1, so that the connection between the faucet lining 2 and the ceramic heating tube 1 is stable and convenient, avoiding the displacement of the faucet lining 2 on the ceramic heating tube 1 during the secondary injection molding process, and ensuring the manufacturing accuracy and sealing reliability. Figure 8 As shown, in this embodiment, the end of the faucet lining 2 is an equilateral triangle as a whole, and the three hollow areas 2-5 are respectively located on the three corresponding sides of the equilateral triangle. After being assembled with the ceramic heating tube 1, the outer wall of the ceramic heating tube 1 can protrude outward from the hollow area 2-5, which facilitates the welding of the power cord 1-1.

[0039] Further, Figure 8 and Fig. 9 As shown, the faucet lining 2 also has a ring body 2-3 sleeved on the outer wall of the ceramic heating tube 1, the ring body 2-3 is connected to the connecting column 2-4, and the water inlet head 3 is wrapped to the outside of the ring body 2-3. The ring body 2-3 can improve the overall structural strength of the faucet lining 2, and the use of the ring body 2-3 also further improves the connection stability between the faucet lining 2 and the ceramic heating tube 1. The faucet lining 2 also has a branching groove 2-6 for limiting the power cord 1-1. Specifically, the branching groove 2-6 can be set on the ring body 2-3, and the branching groove 2-6 is formed by a number of protrusions set on one side of the ring body 2-3, so that the power cord 1-1 can be stuck in the corresponding branching groove 2-6. Fig. 9The connection and wiring structure between the power cord 1-1 and the ceramic heating tube 1 are shown. After the three power cords 1-1 are connected to the lead welding points 1-2 on the ceramic heating tube 1, they are led out from the corresponding branching grooves 2-6 in turn, which can better limit the position where the power cord 1-1 passes through. In actual production, the faucet lining 2 can be connected to the ceramic heating tube 1 first, and the relative positions of the two can be adjusted. Then, the power cord 1-1 is welded to the lead welding point 1-2 where the hollow area 2-5 of the ceramic heating tube 1 is exposed, and the branching groove 2-6 is used to constrain the arrangement of the power cord, and then it is injection molded together with the water inlet head 3 as an insert. Since the power cord 1-1 can be relatively fixed through the branching groove 2-6, it is convenient for the injection molding of the water inlet head 3, and the water inlet head 3 is used to seal and wrap the power cord 1-1. Preferably, the branching grooves 2-6 corresponding to the power lines 1-1 are located on the same side of the faucet lining 2, and the power lines 1-1 pass through the water inlet head 3 and the branching grooves 2-6 in the same direction relative to each other. Figure 4 The figure shows the outlet position of the power line 1-1 on the water inlet head 3. The three power lines 1-1 are arranged in the same direction to facilitate the wiring of the entire ceramic heating tube when it is used in the heating system.

[0040] The utility model discloses a water inlet nozzle packaging structure for a ceramic heating tube, which changes the water inlet sealing process of the existing ceramic heating tube, combines the ceramic production process, plastic part design, plastic injection molding process and rubber encapsulation process, and optimizes the lead welding and lead-out structure, so that the water inlet nozzle seal is integrated on the ceramic heating tube to form an integrated structure, which has the advantages of high integration, compact structure, tight waterproof sealing, convenient manufacturing, low cost, etc. The water inlet nozzle packaging structure of the ceramic heating tube can be used in existing water heaters (such as instant heaters, etc.), especially suitable for water heating systems of smart toilets, and its compact structure is more conducive to installation and improves the safety of smart toilets.
