Description

Technical Field

[0001] The utility model relates to the technical field of water supply devices, and particularly relates to a water nozzle and a heating device. Background Art

[0002] A water nozzle is a commonly used component in a heating device. It is located at the water inlet or outlet. The water nozzle is commonly used to supply water to one end of the heating device for water inlet. After the heating device heats the water body, the water body flows out from the water nozzle at the other end. Its main function is to connect the external water supply pipe with the heating device to achieve continuous water supply and discharge.

[0003] At present, there are various forms of water nozzles. To ensure the sealing performance of the water nozzle in electrical equipment, the water nozzle is often fixed to the heating device by welding. When welding the water nozzle, one end of the water nozzle leans against the water inlet or outlet. Secondly, the end of the water nozzle is welded and formed at the water inlet or outlet to facilitate the connection function of the water nozzle. However, in the above process, the end of the water nozzle extends into the water outlet or water inlet, and it is difficult to ensure that the axis of the water nozzle is parallel to the axis of the water inlet or outlet, resulting in the water nozzle being prone to tilt during welding. The tilted water nozzle increases the welding difficulty during the welding process. At the same time, it also causes the water nozzle to be welded unevenly, resulting in poor sealing and allowing hot water to leak from the connection, affecting the use of the water body. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model uses the support member at one end of the water nozzle to fit with the bottom end surface of the water flow cavity to prevent the water nozzle from tilting before welding. The specific technical solutions are as follows:

[0005] A water nozzle includes a water nozzle body, which includes a hollow nozzle body. The water body can flow from one end of the nozzle body to the other end. A notch is formed at one end of the nozzle body, so that at least one support member is formed at the end of the nozzle body where the notch is located. The end of the support member can fit with a plane, and the axis of the nozzle body is perpendicular to the plane.

[0006] In one embodiment, the number of support members is one, and the arc length of the support member is at least greater than or equal to the arc length of the notch.

[0007] In one embodiment, the support members are evenly distributed on both sides of the end of the nozzle body.

[0008] In one embodiment, the notch is cut in the vertical direction of the axis of the nozzle body.

[0009] In one embodiment, the notch is cut on both sides of the vertical direction of the axis of the nozzle body.

[0010] In one embodiment, the notch is concave inward from both sides of the end of the support member to the middle.

[0011] In one embodiment, the length of the nozzle body along the axis of the nozzle body is H1, and the range is 10-30 mm.

[0012] A heating device is provided with the above-mentioned water nozzle.

[0013] In one embodiment, the heating device includes a first cover plate, a second cover plate, a heat conducting plate and a heating element which are welded in sequence. There is a continuous and curved protrusion on the first cover plate facing away from the second cover plate. A chamber capable of flowing fluid is formed between the inner cavity of the protrusion and the second cover plate. Through holes communicating with the chamber are opened at both ends of the protrusion. The notch of the nozzle body extends into the through holes. The end of the support member is attached to the second cover plate, so that the axis of the nozzle body is parallel to the axis of the through hole.

[0014] From the above technical solutions, it can be seen that the present utility model has the following beneficial effects:

[0015] In the present utility model, a notch is opened at one end of the nozzle body, and a support member with a horizontal end is formed. The support member is attached to the bottom end surface of the flowing water channel, increasing the perpendicularity between the axis of the water nozzle and the bottom end surface of the flowing water channel, avoiding the inclination of the placement between the water nozzle and the through hole, which increases the difficulty of subsequent welding and affects the welding level of the water nozzle. At the same time, it further avoids the problem of leakage at the welding part of the water nozzle. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will combine the drawings and specific embodiments to describe the present utility model in detail. Before elaborating on the technical solutions of each embodiment of the present utility model, the nouns and terms involved will be explained. In this specification, components with the same name or the same reference numeral represent similar or the same structures, and are for illustrative purposes only.

[0022] At present, in order to prevent tilting during the welding process, a boss is often welded around the water nozzle. The boss is stuck on the table surface of the water hole, and then welded into shape. This solution will increase the welding cost of the water nozzle and reduce the production efficiency. Generally, only the end of the water nozzle is flush with the table surface of the water hole or extends into the water hole by a certain part, and then welded. This method requires manual support of the water nozzle, and it is very easy for the water nozzle to tilt during the support process. The tilted welding makes the welding of the water nozzle and the table surface of the water hole not horizontal, and the sealing performance at the welding joint of the water nozzle and the water hole is easily affected.

[0023] As Figure 1 and Figure 3 shown, a water nozzle includes a hollow nozzle body 51. Water can flow from one end of the nozzle body 51 to the other end. A notch is formed at one end of the nozzle body 51, so that at least one support member 54 is formed at the end of the nozzle body 51 where the notch is located. The end of the support member 54 can be attached to a plane, and the axis of the nozzle body 51 is perpendicular to this plane. Among them, when the notch of the water nozzle body 5 extends into the water hole, the support member 54 is flush with and attached to the bottom end of the water hole, that is, the end face of the support member 54 is attached to the bottom end face of the water flow channel in the water hole, so that the axis of the nozzle body 51 is parallel to the axis of the water hole, avoiding the easy tilt of the hand-held nozzle body 51 during welding, so as not to affect the sealing performance of the water nozzle body 5 after welding, and at the same time increasing the connection strength between the water nozzle body 5 and the periphery of the water hole; water flows into the nozzle body 51 from one end, and water flows out from the notch part of the nozzle body 51, so as to avoid the side wall of the nozzle body 51 blocking the water flow, leaving enough space for water flow. The number of support members 54 can be set to multiple. If the number of support members 54 is one, its end is attached to the bottom end face of the water flow channel, which can ensure that the axis of the nozzle body 51 is parallel to the axis of the water hole. However, a single support member 54 is prone to instability during use, so it is preferably to use at least two support members 54. The support members 54 are evenly distributed on both sides of the end of the nozzle body 51, making the attachment of the ends of the support members 54 more stable.

[0024] The cross-section of the nozzle body 51 can be circular or polygonal, and the specific shape is set according to the shape of the water hole. It is preferred that the cross-sections of the water hole and the nozzle body 51 are circular, which helps to reduce the welding difficulty.

[0025] As Figure 3 shown, the notch is cut in the vertical direction of the axis of the nozzle body 51, or the notch is cut on both sides of the vertical direction of the axis of the nozzle body 51. Among them, the notch can be formed at the end of the nozzle body 51 to form one side open, then the support member 54 is an integral arc block, and the arc length of the arc block is at least greater than or equal to the arc length of the notch. The open part is used for water circulation. The notch can also penetrate at the end of the nozzle body 51. For the penetrating opening method of the notch, there are two specific cases as follows:

[0026] Embodiment 1:

[0027] Cut radially from the end of the nozzle body 51 with a cutting tool. The support members 54 are distributed on both sides of the end of the nozzle body 51. At this time, the support members 54 form brackets or struts. This cutting method is simple and only requires one cutting to form. The end face of the support member 54 is fan-shaped, and the fan-shaped end face fits with the bottom end face of the water flow channel to ensure that the axis of the nozzle body 51 is parallel to the axis of the water hole. Secondly, the junction between the periphery of the water hole and the outer periphery of the nozzle body 51 is welded and formed.

[0028] Embodiment 2:

[0029] Cut the two sides of the end of the nozzle body 51 in the radial direction respectively with a cutting tool, so that the remaining part in the middle of the end of the nozzle body 51 forms the support member 54. The support member 54 is a bracket or strut distributed on both sides of the nozzle body 51. This cutting method requires two cuttings to form, and the end face of the support member 54 is fan-shaped.

[0030] Embodiment 3:

[0031] On the basis of Embodiment 2, in order to further improve the accuracy of the placement of the nozzle body 51 in the water hole, a notch opening method of two-cut forming is adopted. The opened shape is concave from both sides of the end face of the support member 54 towards the middle, that is, cut a part towards the middle, so that the end face area of the support member 54 is larger than the cross-sectional area of the middle part, increasing the fitting area between the end face of the support member 54 and the bottom end of the water flow channel, and at the same time ensuring the notch space, which helps to increase the water flow rate.

[0032] Embodiment 4:

[0033] The notch can also be replaced by a hole opened in the radial direction at the end of the nozzle body 51, so that the end of the support member 54 is annular, which can further increase the fitting area between the support member 54 and the bottom end face of the water flow channel and improve the accuracy of the placement of the nozzle body 51.

[0034] As Figure 3 shown, the water nozzle body 5 further includes a guiding portion 53 provided at the end of the nozzle body 51 opposite to the support member 54. The guiding portion 53 and the support member 54 are respectively provided at both ends of the nozzle body 51; the nozzle body 51 and the support member 54 are integrally formed; a clamping groove 52 is provided on the outside of the nozzle body 51. Among them, the guiding portion 53 is used to connect to an external water pipe. The water pipe injects water from one end of the guiding portion 53 into the nozzle body 51 or the water flowing out of the nozzle body 51 flows out through the water pipe. The nozzle body 51 and the support member 54 can be welded and formed, preferably using an integrally formed design. The clamping groove 52 on the outside of the nozzle body 51 facilitates tying up with the end of the water pipe to prevent the water pipe from falling off the nozzle body 51.

[0035] As Figure 2 and Figure 3As shown, the length of the nozzle body 51 along the axis of the nozzle body 51 is H1, and its range is 10 - 30 mm, preferably 15 - 22 mm, which can leave enough space for the water pipe to be sleeved and fixed. At the same time, it also reduces the height of the nozzle body 51 protruding, which is helpful for subsequent installation. The water pipe fits with the outer wall of the nozzle body 51 by extrusion, improving the sealing performance.

[0036] As Figures 1-4 shown, a heating device is installed with the above-mentioned water nozzle. The heating device includes a first cover plate 1, a second cover plate 2, a heat conducting plate 3, and a heating element 4 welded in sequence. A continuous and curved protrusion 11 facing away from the second cover plate 2 is provided on the first cover plate 1. A chamber 13 capable of flowing fluid is formed between the inner cavity of the protrusion 11 and the second cover plate 2. Through holes 12 communicating with the chamber 13 are opened at both ends of the protrusion 11. The notch of the nozzle body 51 extends into the through holes 12, and the end of the support member 54 is attached to the second cover plate 2, making the axis of the nozzle body 51 parallel to the axis of the through holes 12. Among them, the length of the support member 54 along the axis of the nozzle body 51 is H2, and the height of H2 is less than or equal to the cross-sectional height of the protrusion 11, avoiding the notch leaking out from the through holes 12 and affecting the welding process.

[0037] When welding the water nozzle, first insert the support member 54 of the water nozzle into the through holes 12, and the end face of the support member 54 is attached to the second cover plate 2, making the fitting surface of the nozzle body 51 and the second cover plate 2 perpendicular. Secondly, weld and form around the nozzle body 51 and the through holes 12. The welding of the water nozzle is more stable, improving the sealing performance between the water nozzle and the chamber 13 after welding. After welding, the water pipe is sleeved outside the water nozzle body 5 and tightened and limited at the card slot 52. Water is injected into the water nozzle body 5 at one end of the water pipe. The water body flows into the chamber 13 from the notch. The heating element 4 is energized to generate heat, and the temperature is transferred to the second cover plate 2 through the heat conducting plate 3. The second cover plate 2 heats the water body in the chamber 13. After the water body in the chamber 13 is heated, the water body gradually flows out from the notch and the water nozzle body 5 at the other end, realizing the injection, heating, and discharge of the water body.
