Charging seat with conductive needle

Abstract

The invention discloses a charging seat with a conductive needle. The charging seat comprises a body and a conductive needle which is telescopically positioned on the body via an elastic mechanism. The conductive needle forms a charging electrode. The part stretching out of the body of the conductive needle is at least higher than the distance between a host and the body during charging. After being pressed, the conductive needle which is supported by the elastic mechanism is in pressure contact with a charging electrode on the host. According to the invention, the conductive needle is used as the charging electrode for being in contact with and charging the charging electrode of the host; the conductive needle is telescopically positioned on the body via the elastic mechanism and the elastic mechanism bears pressure and is shrunk during charging, so pressure contact between the conductive needle and the charging electrode on the host is maintained, effective contact between the host and the charging seat body during the charging is ensured, and stability is improved.

Description

technical field [0001] The invention belongs to the technical field of structural design of a charging seat for a rechargeable vacuum cleaner, and in particular relates to a charging seat with conductive needles. Background technique [0002] Stick vacuum cleaner is a kind of dust removal tool, which has gradually increased in recent years. Most of them are rechargeable structures. They are characterized by small size and convenient use, so they are widely used. [0003] The main reason for the dust removal of the stick vacuum cleaner is that its "head" is equipped with an electric exhaust fan. There is a wind impeller on the shaft of the exhaust fan. After power on, the exhaust fan will generate strong suction and pressure at a speed of 500 cycles per second. Sufficiently replenish the air in the fan, resulting in an instant vacuum inside the vacuum cleaner, which forms a negative pressure with the external atmospheric pressure. After the filter is purified, it is dischar...

Problems solved by technology

[0005] At present, the charging form is mostly in the form of charging shrapnel. The charging shrapnel is fixed on the charging stand to form a charging electrode. The charging principle is to use the principle of elastic deformation of the shrapnel itself to form a stable contact with the charging electrode on the main body of the vacuum cleaner for charging. However, Due to the limited elastic deformation of this kind of shrapnel, and after a long period of use, the shrapnel is prone to elastic failure, lacks stability, and is inconvenient to replace and maintain.

[0006] Therefore, in view of the above problems, it is necessary to propose a new type of charging stand structure, which can effectively solve the problem of poor charging contact stability in the prior art, ensure effective contact between the charging electrodes of the host and the charging stand during charging, and improve stability. And easy maintenance management
