Description

Technical Field

[0001] The invention relates to the technical field of office supplies, in particular to a desktop multi-purpose hand warmer. Background Art

[0002] Hand warmers are automatic heating health care products developed using physical and chemical principles. They can be roughly divided into three types: one is to generate heat by heating water, which is what we commonly call a hot water bag. Unlike traditional hot water bags, electric hot water bags save the trouble of adding water. Just plug in the power and wait for more than ten minutes to generate heat. In fact, the water inside is boiled, so the temperature is generally very high; one is to generate heat through chemical reactions. The hand warmers on the market are of this type. Heat is generated through the contact of the chemical substances inside; the other is to use lithium battery function, the internal heating plate generates heat, and the USB interface is used for charging and discharging, which is similar to a hand warming mouse pad. Due to the charge and discharge function of lithium batteries, they can generally be used as a mobile power source.

[0003] However, most of the existing hand warmers require the palms to be pressed tightly against them, which will reduce office efficiency. Most of the existing hand warmers have a small heating range and cannot warm both hands at the same time. In addition, the functions of the existing hand warmers are relatively single. Therefore, it is imperative to invent a hand warmer with a large heating range and a desktop cleaning function. Summary of the invention

[0004] In view of the above situation, in order to solve the defects of the prior art, the purpose of the present invention is to provide a desktop multi-purpose hand warmer, which can effectively solve the problems that most of the existing hand warmers have a small heating range and cannot warm both hands at the same time, and the functions of the existing hand warmers are relatively single.

[0005] The technical solution solved by the present invention is that it includes a first shell and a second shell, the interiors of the first shell and the second shell are both hollow structures, a dust removal mechanism is arranged under the first shell, a first adjustment through hole is opened on the side of the first shell, the second shell is slidably arranged in the first shell, a second adjustment through hole is opened on the side of the second shell, adjustment mechanisms are arranged inside the first adjustment through hole and the second adjustment through hole, a contraction mechanism is arranged inside the first shell and the second shell, and a heating mechanism is arranged inside the contraction mechanism; when it is needed, the first shell and the second shell are pulled by hand, the first shell and the second shell drive the contraction mechanism to expand, the heating mechanism heats, and then the warm air is transported to the interior of the first shell and the second shell through the contraction mechanism, and then blown toward the human body after being adjusted by the adjustment mechanism, the dust removal mechanism can remove dust from the desktop to avoid dust being raised when heating and blowing air; the hollow interiors of the first shell and the second shell provide expansion space for the contraction mechanism.

[0006] The present invention adopts a retracting mechanism and an adjusting mechanism to expand and contract the sliding tube and the storage tube, and adjust the adjusting leaves to expand the heating range. It adopts a dust removal mechanism to generate suction through the impeller to clean the dust on the desktop, so that the hand warmer has a desktop cleaning function. This is an innovation in hand warmers. BRIEF DESCRIPTION OF THE DRAWINGS
