Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more features.

[0044] With the widespread application of electronic pens, they are used in tablet computers, office computers, mobile phones and other fields. Existing electronic pens generally include a pen body and a refill component inside the pen body. The waterproof effect of electronic pens is not good. They can only prevent dust and a small amount of water stains from entering through the pen tip, which roughly meets the IPX3 function (IPX0: no protection; IPX1: can prevent the intrusion of vertical falling water drops; IPX2: can prevent the intrusion of falling water drops at a 15-degree angle; IPX3: can prevent the intrusion of 60-degree spray water; IPX4: can prevent the intrusion of splashing water; IPX5: can prevent the intrusion of low-pressure water spray; IPX6: can prevent the intrusion of high-pressure water spray; IPX7: can prevent short-term immersion in water). However, if the electronic pen falls into the water, water will enter the inside of the electronic pen through the pen tip, which cannot meet the waterproof requirements.
[0045] In view of this, an embodiment of the present application provides an electronic pen to overcome at least one of the above-mentioned technical problems.
[0046] See also Figure 1In the embodiment of the present application, the electronic pen includes a pen body 10, a pressure sensing component 20, a bracket 30, a first seal 40, a pen head component 50 and a second seal 60.
