Description

Technical Field

[0001] The utility model relates to the technical field of thermos cups, in particular to an anti-scalding heat-insulating thermos cup. Background Art

[0002] Thermos cup is used to store tea and can keep the tea warm. It is generally a water container made of ceramic or stainless steel with a vacuum layer. It has a lid on the top and is tightly sealed. The vacuum insulation layer can delay the heat dissipation of the water and other liquids inside to achieve the purpose of insulation.

[0003] An existing anti-scalding and heat-insulating thermos cup (authorization announcement number CN220256215U) has the following defects: the above-mentioned device collects water droplets at the lower end of the thermos cup cover through a water retaining shell, and then guides the water droplets downward and discharges them through the drainage through hole and the guide vertical hole. However, the water droplets will be guided to the bottom of the thermos cup. When the thermos cup is placed on a table, the water droplets are easy to drip onto the table to form water stains, which is inconvenient for users to use in daily life. For this reason, we propose the utility model. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Please see attached Figure 1 -Attached Figure 6 A scald-proof heat-insulating cup comprises a cup body 1, a cup cover 2 is threadedly connected to the top surface of the cup body 1, a collecting structure is arranged inside the cup body 1, and the collecting structure comprises a mounting plate 201 fixed inside the cup body 1, two telescopic cylinders 202 are fixed on the top surface of the mounting plate 201, a movable rod 203 is slidably inserted inside the telescopic cylinder 202, a spring 204 is arranged inside the telescopic cylinder 202, the top end of the spring 204 is fixed to the bottom end of the movable rod 203, a filter screen 205 is fixed on the top end of the movable rod 203, a scraper 206 is fixed on the top surface of the filter screen 205, and a heat-insulating block 207 is fixed on the inner top surface of the cup cover 2. By setting the collecting structure, when the staff covers and tightens the cup cover 2 on the cup body 1, When the cup cover 2 is raised, the insulation block 207 on the top surface of the cup cover 2 abuts against the scraper 206 and contracts the spring 204. When the cup cover 2 is twisted to take it out, the bottom surface of the insulation block 207 continuously rotates on the top surface of the scraper 206, so that the scraper 206 scrapes off the water droplets formed on the bottom surface of the insulation block 207, and the water droplets re-enter the cup body 1 from the cup cover 2, so that the water droplets will not fall outside the cup body 1 to form water stains, thereby facilitating the user's use in daily life. The cup mouth and the cup body 1 are threadedly connected, so that the cup mouth can be disassembled for cleaning. The thread direction between the cup mouth and the cup body 1 is opposite to the thread direction between the cup cover 2 and the cup mouth, so that the cup mouth and the cup body 1 will not be separated when the cup cover 2 is twisted.

[0024] In the embodiment, a vacuum cavity 3 is opened inside the cup body 1, and a nitrogen cavity 301 is opened inside the cup body 1. The vacuum cavity 3 is a vacuum layer in which the air is evacuated from the cup body 1, and the nitrogen cavity 301 is a nitrogen layer in which nitrogen is injected into the cup body 1. The vacuum layer and the nitrogen layer form a double-layer insulation in the cup body 1 to improve the insulation effect.

[0025] In the embodiment, a heat-resistant cavity 4 is opened inside the insulation block 207, and a rubber ring 401 is fixed between the cup cover 2 and the insulation block 207. The heat-resistant cavity 4 is vacuum, and the rubber ring 401 makes the cup body 1 and the cup cover 2 tighter when the cover is closed, thereby improving the sealing of the thermos cup. The heat-resistant cavity 4 and the rubber ring 401 can improve the thermal insulation performance of the cup cover 2 to prevent heat loss.

[0026] In the embodiment, a filling cavity 5 is opened inside the cup cover 2, and polyurethane foam 501 is fixed inside the filling cavity 5. The polyurethane foam 501 is a prior art. The thermal insulation performance of the cup cover 2 can be further improved by filling the cup cover 2 with foaming material.

[0027] In the embodiment, a fixing groove 6 is provided on the bottom surface of the cup body 1. The fixing groove 6 is annular. An anti-slip ring 601 is fixed inside the fixing groove 6. The anti-slip ring 601 is made of rubber. The anti-slip ring 601 can increase the friction between the bottom surface and the contact surface of the cup body 1 when it is placed, thereby improving the safety of placing the cup body 1. At the same time, the fixing groove 6 fits and protects the inner and outer walls of the anti-slip ring 601 to prevent the anti-slip ring 601 from deformation during use.

[0028] In the embodiment, the bottom surface of the cup body 1 is concave, and the concave bottom surface of the cup body 1 can ensure that the cup body 1 is stably supported on any placement platform, thereby preventing the cup body 1 from tipping over.

[0029] Working principle: During use, when the staff covers and tightens the cup cover 2 on the cup body 1, the heat insulating block 207 on the top surface of the cup cover 2 abuts against the scraper 206 and contracts the spring 204. When the cup cover 2 is twisted to take it out, the bottom surface of the heat insulating block 207 continuously rotates on the top surface of the scraper 206, so that the scraper 206 scrapes off the water droplets formed on the bottom surface of the heat insulating block 207. The water droplets re-enter the cup body 1 from the cup cover 2 through the filter 205, so that the water droplets will not fall outside the cup body 1 to form water stains. The vacuum cavity 3 is a vacuum layer in the cup body 1 where air is evacuated, and the nitrogen cavity 301 is a nitrogen layer in the cup body 1 where nitrogen is injected. The vacuum layer and the nitrogen layer form a double vacuum layer in the cup body 1. The rubber ring 401 makes the cup body 1 and the cup cover 2 tighter when they are closed, thereby improving the sealing of the thermos cup. The heat-resistant cavity 4 and the rubber ring 401 can improve the thermal insulation performance of the cup cover 2. The thermal insulation performance of the cup cover 2 can be further improved by filling the cup cover 2 with foaming material. The anti-slip ring 601 can increase the friction between the bottom surface and the contact surface of the cup body 1 when it is placed, thereby improving the safety of placing the cup body 1. At the same time, the fixing groove 6 fits and protects the inner and outer walls of the anti-slip ring 601 to prevent the anti-slip ring 601 from deformation during use. The concave bottom surface of the cup body 1 can ensure that the cup body 1 is stably supported on the same placement platform to prevent the cup body 1 from tipping over.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
