Description

Technical Field

[0001] The utility model relates to a heater, in particular to a heater sealing structure. Background Art

[0002] For example, a high-pressure water heater housing sealing structure disclosed in CN212422747U includes a housing and a cover plate, wherein the cover plate is arranged on both sides of the housing, a groove is arranged on the housing, a sealant is arranged in the groove, and a protrusion matching the groove is arranged on the cover plate. The protrusion on the cover plate matches the groove, and the cover plate can be connected to the housing by inserting the protrusion into the groove arranged on the housing; a sealant is also arranged in the groove, which can fix the protrusion inserted into the groove on the one hand, strengthen the connection state of the cover plate, and seal the housing on the other hand to prevent liquid from flowing out or flowing in, thereby ensuring that the water heater and the electric vehicle can work safely. However, after the cover plate is pressed into the structure, the sealant in the sealing groove is easy to overflow to the surface, requiring secondary cleaning, increasing the process and increasing the cost. In addition, since the protrusion of the cover plate needs to be inserted into the groove, the processing precision of the protrusion is required to be high, resulting in high cost. Utility Model Content

[0003] In order to solve the above-mentioned problem that the overflow glue needs to be cleaned up, resulting in an increase in the number of processes and a high overall cost, the utility model provides a heater sealing structure, and the specific technical solution is as follows:

[0004] A heater sealing structure comprises: a shell, on which a sealing plane is provided; and a cover plate, on which a sealing fold is provided and a plurality of glue storage protrusions protruding toward the inside of the cover plate, the glue storage protrusions being arranged opposite to the sealing plane; wherein, the cover plate covers the sealing plane, the sealing fold is sleeved on the outside of the shell, and the glue storage protrusions abut against the sealing plane, so that a glue storage space is formed between the sealing plane and the cover plate.

[0005] Preferably, there are several screw holes on the sealing plane; the cover plate is provided with several connecting holes corresponding to the screw holes one by one, and the connecting holes are fixed to the screw holes by screws.

[0006] Furthermore, a plurality of rubber retaining rings are provided on the sealing plane, and the rubber retaining rings are located at the top of the screw holes.

[0007] Furthermore, a plurality of conductive convex ribs are provided on the top of the rubber retaining ring, and the conductive convex ribs are against the cover plate.

[0008] Furthermore, the height of the glue retaining ring is not greater than the height of the glue storing protrusion.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The utility model provides a heater sealing structure that can overflow the sealant to the inside without affecting the appearance, reducing the process of surface glue discharge, and having a good sealing effect. At the same time, it reduces the requirements for cover plate accuracy, improves fault tolerance, and reduces costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is now further described with reference to the accompanying drawings.

[0020] like Figures 1 to 8 As shown, a heater sealing structure includes a shell 1 and a cover plate 2, wherein a sealing plane 10 and a plurality of screw holes 13 are provided on the top of the shell 1, and the screw holes 13 are located on the sealing plane 10; a sealing fold 21 is provided along the edge of the cover plate 2, and a plurality of connecting holes 23 and glue storage protrusions 22 are also provided on the cover plate 2, wherein the connecting holes 23 are through holes and correspond one to one with the screw holes 13, and the glue storage protrusions 22 protrude toward the inside of the cover plate 2, that is, toward the direction of the sealing fold 21, and the glue storage protrusions 22 are also arranged along the sealing fold 21, and the glue storage protrusions 22 are regularly arranged, and the glue storage protrusions 22 are also arranged opposite to the sealing plane 10, and are used to abut against the sealing plane 10, so that a certain gap is formed between the cover plate 2 and the sealing plane 10, and the gap is used to store the sealant to form a reliable seal.

[0021] During installation, first apply sealant on the sealing plane 10. The sealant has a certain height, and the height of the sealant must be greater than the height of the sealant storage protrusion 22. The sealant is also arranged along the contour of the sealing plane 10 to form an annular sealing ring. Then the cover plate 2 is installed on the sealing plane 10, and the sealant storage protrusion 22 is against the sealing plane 10. The annular sealant is filled between the sealing plane 10 and the cover plate 2. Due to the existence of the sealing fold 21, excess sealant overflows into the gap between the sealing fold 21 and the shell 1 and overflows into the interior of the shell 1, thereby ensuring that the sealant will not overflow to the outside of the sealing fold 21. There is no need to clean the sealant, which reduces the process and reduces the processing difficulty of the cover plate 2, thereby reducing the cost as a whole.

[0022] The connection holes 23 on the cover plate 2 correspond to the screw holes 13 on the housing 1 one by one, and then the cover plate 2 is fixed to the housing 1 by screws.

[0023] Since the sealant has a certain height, it can completely achieve the sealing between the cover plate 2 and the sealing plane 10, effectively ensuring the sealing effect.

[0024] In order to prevent the sealant from entering the screw hole 13, a plurality of sealant retaining rings 11 corresponding to the screw holes 13 are provided on the sealing plane 10. The sealant retaining rings 11 are located at the top of the screw holes 13. When the cover plate 2 is pressed onto the sealing plane 10, the sealant retaining rings 11 can prevent the sealant from entering the screw hole 13. The height of the sealant retaining ring 11 is not greater than the height of the sealant storage protrusion 22, and is usually less than the height of the sealant storage protrusion 22 to avoid affecting the sealing performance.

[0025] A plurality of conductive ribs 12 are provided on the top of the rubber retaining ring 11. Four conductive ribs 12 can be provided in a circular array. The conductive ribs 12 are against the cover plate 2. The conductive ribs 12 are pressed against the cover plate 2 by the screws, so that the cover plate 2 and the housing 1 are connected. The housing 1 is usually a die-casting, and the cover plate 2 is a stainless steel cover plate 2. Both are metal parts and need to be grounded after connection to improve safety. The conductive ribs 12 can effectively ensure the connection between the cover plate 2 and the housing 1.

[0026] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the claims of the present invention.
