Description

portable heater

technical field

The utility model relates to the technical field of heaters, in particular to a portable heater.

Background technique

A heater is one of the commonly used electrical appliances in daily life. For example, a milk warmer is a kind of heater, and a water cup is also provided with a heater.

However, other general-purpose heaters currently have the following problems in heating milk, breast milk, water, tea, etc.:

Most of the existing heaters use 110-240V to directly supply power to the heating element. Not only are they bulky, but they are also relatively heavy and inconvenient to take out. Moreover, they cannot work without a power supply when traveling outdoors, which brings inconvenience to users when traveling.

In order to solve the above problems, portable heaters have also appeared. The existing portable heaters are usually directly connected to the bottle mouth of the bottle to be heated, and then the bottle to be heated is buckled upside down on the heater, and the heating area is usually small. The heating is slow, so the user needs to wait for a long time when heating, and because the heating area is small, it is easy to heat unevenly, and it is easy to destroy the nutrients of milk, breast milk, etc. Moreover, the heater has less waterproof design, which is inconvenient to clean.

When the heater is specially used for warming milk, the heater and the feeding bottle are connected by threads, which is inconvenient to use, and the sealing ring at the connection between the heater and the feeding bottle is U-shaped, which is not easy to take out and clean, and blocks the heating area, affecting heating efficiency.

detailed description

In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Therefore, a feature indicated in this specification will be used to describe one of the features of an embodiment of the present invention, rather than implying that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes a number of features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly described. Thus, the illustrated combinations are not intended to be limiting unless otherwise stated.

The principle of the present utility model will be described in detail below in conjunction with the accompanying drawings and embodiments.

As shown in Figure 1, the portable heater of the present invention includes a housing 1, and a rechargeable battery 2 is arranged in the housing 1. In this embodiment, the rechargeable battery 2 is a lithium battery, and the rechargeable battery 2 and the heating plate 3 Electrically connected, the heating plate 3 transmits heat to the liquid in the bottle to be heated through a metal bottle cap 4 again. In this embodiment, the metal bottle mouth 4 is integrally made of stainless steel.

The heating plate 3 is located at the opening of the housing 1, the metal bottle cap 4 covers the entire opening of the housing 1, and the heater is sealed and connected with the bottle mouth of the bottle to be heated (not shown in the figure) through the metal bottle cap 4. The part of the new metal bottle cap 4 that is located in the bottle to be heated protrudes to a certain height toward the inside of the bottle to be heated, that is, the part of the metal bottle cap 4 that is located in the bottle to be heated is cylindrical or truncated, so that the metal bottle cap 4 There are two heating surfaces for the liquid in the bottle to be heated, one is the top surface of the protruding part, and the other is the side of the protruding part, which greatly increases the heating area and improves the heating efficiency. In a preferred embodiment, the part of the metal bottle cap 4 positioned in the bottle to be heated is cylindrical, assuming that the radius of the cylinder is 20mm, and the side height (the height of the protrusion) is 14mm, then the promotion ratio of the heating area= Side area/Cylinder top surface area=(2*Π*20*14)/(Π*20*20)=140%. Compared with U-shaped sealing ring, L-shaped sealing ring can increase the heating area = ((43/2)^2-(41/2)^2)Π/((41/2)^2Π)≈10%, so the heating area is total 150% increase.

In one embodiment, with the bottleneck of the bottle to be heated as the starting plane, the height of the part of the metal bottle cap 4 positioned in the bottle to be heated can be less than the height of the part positioned outside the bottle to be heated, so that the heating area still has two parts , only the side area is less. In a preferred embodiment, the part of the metal bottle cap 4 located in the bottle to be heated and the part outside the bottle to be heated can be located on the same plane, so that the side area is relatively larger than that of the previous embodiment. Said to increase, the heating efficiency is relatively improved, and in another preferred embodiment, the height of the part of the metal bottle cap 4 positioned in the bottle to be heated can be greater than the height of the part positioned outside the bottle to be heated, so that the heating area can be further improved. improvement.

The metal bottle cap 4 of the utility model is provided with a circle of groove 5, through which the bottle to be heated is connected with each other, and the bottom of the groove 5 is provided with an L-shaped sealing ring that abuts against the mouth of the bottle to be heated 6. Compared with the U-shaped sealing ring, the L-shaped sealing ring is more convenient to take, place and clean, and one side of the L-shaped sealing ring is located at the bottom of the groove, and the other side is located on the inner wall of the groove outside the bottle to be heated One side, that is, the side of the inner wall with a larger inner diameter of the groove, that is, the part where the metal bottle cap is located in the bottle to be heated does not have a sealing ring structure, so that compared with the U-shaped sealing ring, it further increases the heating liquid and the metal bottle. The heated contact area of the lid.

The side wall of the groove and the side wall of the bottle mouth of the bottle to be heated are provided with a connection structure that cooperates with each other. The specific connection structure used can be a thread structure or a buckle structure. For example, the groove is located on the side wall outside the bottle to be heated and is provided with an internal thread, and the outside of the bottle mouth of the bottle to be heated is provided with an external thread, and the two are screwed together. For example, the groove is located on the side wall outside the bottle to be heated. It can cooperate with the buckle 7 of the external thread on the outside of the bottle mouth of the bottle to be heated to be snapped together. The setting positions of the screw thread and the buckle structure are determined according to specific conditions, and are not limited to the specific embodiments of the present invention.

The charging interface of the rechargeable battery of the present utility model adopts the Type-C interface 8, which occupies a small area of the housing, and is not easy to cause damage to the charging interface due to wrong insertion. And the charging interface place of rechargeable battery can also be provided with waterproof soft rubber plug 9. A waterproof sealing ring 10 can also be provided at the joint between the metal bottle cap and the shell, so that the entire heater has a good sealing and waterproof effect. Once the milk or tea stains are contaminated, it is also convenient to clean, and there is no need to worry about soaking the internal electronic components. .

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
