TECHNICAL FIELD

[0001] The utility model relates to the field of straw, specifically, relate to a dustproof function's straw. BACKGROUND

[0002] In daily life, the straw for drinking water is widely used in the catering industry. However, due to the epidemic, air pollution and other reasons, especially in crowded places, dust, bacteria and other harmful gases spread in the air in large quantities, seriously endangering people's health, and the original simple and unshielded straw can no longer meet the increasing demand of consumers. For example, most young people now like to drink coffee, milk tea and other drinks on the subway or in the street, and because the straw mouth is not shielded, the straw mouth is exposed to the air, which will inevitably have dust, bacteria and other harmful gases attached to the straw mouth and then inhaled into the body. In view of this kind of deficiency, there are currently various related improvements, such as patent numbers 202110219965.X and 202220646444.2 installing a cover on the straw, which can partially solve the problem, but the solution is not perfect, and the production cost is high, and the practicability is poor.

[0003] Therefore, the present application is proposed. UTILITY MODEL CONTENT

[0015] Please refer to Figures 1-4 The present embodiment provides a dustproof straw, which comprises a straw body 1 and a dust cover 2, the dust cover 2 is sleeved on the upper middle part of the straw, such as Figure 1As shown, in actual production, in order to facilitate use, the straw of the utility model is designed with one more length of dustproof sleeve than the conventional straw. The dustproof sleeve 2 is a hollow cylinder, the lower end surface is not shielded, the upper end surface is fixedly provided with soft rubber sheets, the soft rubber sheets are stacked together in petal shape, completely cover the upper end surface of the dustproof sleeve 2, and the soft rubber sheets are arranged in two semicircular shapes and are stacked together, as shown. Figure 4 As shown. The pipe body 1 and the dustproof sleeve 2 are made of polypropylene material (PP), and the soft rubber sheets are made of food-grade soft rubber, such as food-grade silicone rubber.

[0016] The first fixing member is arranged in the dustproof sleeve 2, and the second fixing member is correspondingly arranged on the straw body 1, and the first fixing member and the second fixing member are matched to fix the dustproof sleeve 2 on the straw body 1. The first fixing member and the second fixing member can have various specific implementation manners, preferably, a clamping piece that is clamped with each other can be used. A clamping groove can also be used.

[0017] In the original position of the dustproof straw of the utility model, the dustproof sleeve 2 is below the straw body 1, as shown. Figure 1 At this time, the soft rubber sheets are wrapped around the outer periphery of the straw body 1. When it is necessary to cover the upper end port of the straw body, the dustproof sleeve 2 is pulled upwards until the first fixing member and the second fixing member are clamped and fixed, at this time, the upper end port of the straw body is deeply arranged in the dustproof sleeve 2, and the soft rubber sheets will gradually cover and shield the upper end port of the dustproof sleeve 2 due to the material properties and gravity, so as to prevent dust in the air from adhering to the upper end port of the straw body or floating into the straw.

[0018] In order to better fix the dustproof sleeve 2 on the straw body 1, in the optimization mode, the first fixing member can be provided as two, which are arranged at the upper end and the lower end of the inner wall of the dustproof sleeve 2, and the clamping pieces are smooth arc surfaces. Because the material of polypropylene has a certain hardness, the clamping piece can play a certain fixing role, which is enough to support the fixation of the dustproof sleeve 2; but because the thickness of the straw is thin, it has a certain elasticity, when the force is certain, the fixation will be damaged, so that the dustproof sleeve 2 can slide back and forth on the straw body 1. The first fixing member arranged at the upper end of the dustproof sleeve 2 can make the dustproof straw of the utility model more stable in the initial state, and improve the use experience of the product.

[0019] As a further improvement of the scheme. In order to make full use of this configuration of the scheme, the clamping piece of the first fixing member and the second fixing member provided on the upper end of the dustproof sleeve 2 is provided as a right angle surface, and the thickness is provided as twice the thickness of the first fixing member at the lower end of the dustproof sleeve 2, so as to improve the tendency of the dustproof suction tube in the initial state to resist the downward sliding of the dustproof sleeve 2. The improvement is to solve the problem of the force of the suction tube. Since the wall of the disposable suction tube is usually thin, and the diameter of some tubes is too thin, it is not convenient to force when inserting the tube. The improvement of the utility model will facilitate the user to directly pinch the dustproof sleeve 2 and force, which will be more convenient for the user to insert the tube. And in the improved scheme, the first fixing member at the lower end of the dustproof sleeve 2 is unchanged, and it still has the elasticity of the previous scheme, and does not affect the fixing and sliding function of the dustproof sleeve 2 on the suction tube body 1.

[0020] The above only describes the preferred embodiments of the utility model and is not used to limit the utility model. For those skilled in the art, the utility model can have various changes and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
