Technical Field

[0001] The utility model relates to a novel spray head for a chain, belonging to the technical field of spraying accessories. Background Art

[0002] Bicycle / electric vehicle chains require lubricant spraying for maintenance. Traditionally, lubricant spraying is typically achieved through a slender nozzle plugged into the nozzle of a spray can. The applicant believes that nozzle spraying can result in incomplete and uneven application, and the nozzle itself is easily lost, suggesting that there is still room for improvement. Therefore, the applicant has designed a new spray nozzle for chains and filed the following application. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] As Figures 1-6 shown: a new spray head for chain, comprising spray head cover 1 and spray head base 2 two parts, spray head cover 1 and spray head base 2 are assembled through the upper and lower of the several plug-in columns, plug-in holes set by each other, to form the spray head with flow passage inside.

[0023] Further, the above-mentioned spray head has a limiting part 201 for limiting both sides of the chain link, which is formed below the front end of the spray head base 2, and specifically by two plate bodies 211, the distance between which is equal to or slightly greater than the width of the chain link, so as to limit it and prevent it from shaking left and right during spraying, affecting the spraying effect. The area between the two plate bodies 211 of the spray head base forms a spray liquid part 202 with a plurality of spray holes 212 along the direction of the chain link. When the chain link is in the limiting state, the spray holes 212 are located directly above it, so that the lubricant can be sprayed from top to bottom on each side of the chain link.

[0024] Specifically, in addition to forming the above-mentioned spray liquid part 202, the spray head base 2 also forms a stop part 203 below the spray liquid part 202. When the limiting part 201 limits the chain link, if the chain link is stopped by the stop part 203, it means that the spray holes of the spray liquid part 202 are already in the closest position to the chain link, and will not be blocked by the chain link. At this time, the optimal spraying effect can be achieved. Of course, the stop part 203 is also formed with symmetrical arc-shaped guide slides 213 on both sides. The chain can slide back and forth more easily with the help of the guide slides 213, so as to adjust the spraying position of the lubricant on the chain link.

[0025] Further, the top of the above-mentioned spray head base 2 is integrally formed with a flow cavity platform 204 with a groove, and the bottom of the spray head cover 1 is correspondingly formed with an enclosing wall 101. When the spray head cover 1 and the spray head base 2 are combined, the flow cavity platform 204 can be embedded with the enclosing wall 101. At this time, the groove of the flow cavity platform 204 is sealed by the bottom surface 1 of the spray head cover, so as to form the flow channel for allowing the lubricant to flow. Of course, the rear end of the spray head base 2 is also formed with a liquid inlet part 205. When the spray head is installed on the spray tank, the inner tube of the spray tank will extend upward into the liquid inlet part 205. Since the inner wall of the liquid inlet part 205 is formed with a protruding pressing body 215, the pressing of the spray tank can be realized by the pressing body 215, so that the lubricant is sprayed into the liquid inlet part 205, and then flows from the flow cavity to the spray liquid part 202, and finally sprayed on the surface of the chain link by the spray holes 212.

[0026] Specifically, in order to improve the pressing feeling of the spray head, the top surface of the spray head cover 1 is also formed with a partition part 102 at the middle position. If so, the user's two fingers need to press the spray head on both sides of the partition part 102, which helps to balance the pressing force of the spray head, making it easier to spray with one hand. In addition, the part of the spray head cover 1 that contacts the two fingers can also be appropriately provided with some anti-slip patterns 103 for providing anti-slip function.

[0027] In the prior art, the spray head of the traditional spray can sprays solvent in the shape of an umbrella, and in order to concentrate the spraying effect, an elongated spray pipe can be inserted into the spray head, but whether the spray pipe is inserted or not, the spray can always sprays in the front direction, which results in the problem of incomplete spraying on the inner side of the chain.

[0028] It can be understood that the utility model is described through some embodiments, and the person skilled in the art knows that various changes or equivalent replacements can be made to these features and embodiments without departing from the spirit and scope of the utility model. In addition, under the guidance of the utility model, these features and embodiments can be modified to adapt to specific conditions and materials without departing from the spirit and scope of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application belong to the scope protected by the utility model.
