The utility model provides a constant temperature chopsticks, for making the utility model discloses a purpose, technical scheme and effect are clearer, more clear and definite, and it is right to refer to the attached drawing below and to lift the embodiment the utility model discloses further detailed description. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1, 2, 3, 4, 5 and 6, the utility model provides a pair of constant temperature chopsticks, the length of each chopstick is close to that of a pair of conventional chopsticks, the length of each chopstick is about 25-30 cm, each chopstick comprises a holding part 1 and a clamping part 2 which are connected through end parts, each holding part 1 is of a tubular structure, an opening at one end is an open end 1.1, the other end is closed to a closed end 1.2, a circular cavity 1.3 is arranged inside each holding part, a refrigeration bag 3 is arranged in each cavity, each refrigeration bag is of a slender structure, the diameter of each refrigeration bag is close to that of each cavity, refrigeration materials are filled in each refrigeration bag, and a heat insulation layer 4 is further coated outside each holding part; the clamping part 2 is a solid cylinder, one end of the clamping part is a connecting end 2.1, the other end of the clamping part is a clamping end 2.2, the diameter of the connecting end 2.1 is the same as the inner diameter of the opening end 1.1 of the holding part 1, and the clamping part 2 is detachably connected with the opening end 1.2 of the holding part 1 through the connecting end 2.1 to form a complete chopstick.

The chopsticks with the structure and the refrigeration bag 3 arranged in the holding part 1 can keep the temperature of the clamping part 2 close to that of uncooked and cold food, so that the taste sense of the food can not be changed due to the temperature rise of the food caused by the chopsticks in the clamping process, and the taste sense enjoyment of people is met.

In the structure, an internal thread is arranged in the opening end 1.1 of the holding part 1, and meanwhile, as shown in fig. 3, an external thread matched with the opening end 1.1 is arranged at the connecting end 2.1 of the clamping part 2, and the connecting end 2.1 is connected with the opening end 1.1 through a thread. Threaded connection has better stability and leakproofness, even if experience and dismantle the assembly many times, still can keep the stability of connection, also avoids air and refrigeration bag contact simultaneously, carries out the heat exchange.

As shown in fig. 4, in the above structure, the closed end 1.2 of the grip portion 1 is further provided with a screw cap 1.4. The spiral cover 1.4 can seal one end of the holding part 1, and the refrigeration bag 3 is prevented from falling out in the using and cleaning processes. When the refrigeration bag 3 is replaced, the screw cap 1.4 is opened, and the refrigeration bag 3 can be conveniently pushed out from the opening end 1.1 through a slender tool.

As a variant, the closing section 1.2 of the grip part 1 can be provided with a spring-loaded button 1.5, as shown in fig. 5. The button 1.5 can not only seal the tail end of the holding part 1, but also adjust the position of the refrigeration bag 3, so that the refrigeration bag 3 is fully abutted against the clamping part 2. Meanwhile, when the refrigerating bag 3 is replaced, the button 1.5 is pressed, so that the refrigerating belt 3 can be pushed out from the opening end 1.1 without other tools.

As shown in fig. 1, fig. 3 and fig. 4, preferably, in the above structure, the holding end 2 is provided with a corrugated ring 2.3, the corrugated ring can improve the holding capacity of the holding end 2, when holding sashimi and cold food with tender and smooth tingling, the smooth holding end is not enough in holding capacity, the corrugated ring 2.3 can improve the friction force of the holding end on one hand, and is more beautiful and exquisite on the other hand, and the texture and the grade of the chopsticks are improved.

Preferably, in the thermostatic chopsticks, the clamping part 2 is made of metal, and the metal has good heat conductivity. The link of clamping part 2 and the contact of refrigeration bag, the clamping part of metal material can be better through the cooling of refrigeration bag 3 to the temperature that makes the clamping part is close to the temperature of cold food, makes the taste that cold food kept the preferred during the centre gripping. More preferably, the clamping portion is made of stainless steel, has a good heat conductivity coefficient, and is low in cost and easy to accept by consumers.

In the structure, the length of the chopsticks is close to that of the conventional chopsticks, wherein the length of the clamping part 2 is smaller than that of the holding part 1, so that the space of the cavity 1.3 in the holding part 1 is longer, the longer the refrigerating bag 3 can be placed, and the longer the time for keeping the clamping part at the low temperature is. Preferably, the ratio of the length of the clamping part 2 to the length of the holding part 1 is 1: 3-4.

In the above structure, the refrigerating bag 3 is filled with a material with large heat capacity, which may be ice or scientific ice. Preferably, the refrigeration effect that has the preferred when the refrigerant in the refrigeration bag 3 is scientific and technological ice, can make the temperature of clamping part 2 keep low temperature for a long time, and scientific and technological ice can be high temperature resistant simultaneously, and volume heat altered is little, can use repeatedly many times.

The material of the gripping part 1 is plastic, has heat insulation performance, enables the ice bag to be less affected by the outside, enables the refrigeration effect of the refrigeration bag to be better, and is lighter in plastic material.
