Description

Upper and lower telescopic solenoid valve

The invention relates to an up-and-down telescopic solenoid valve, which is suitable for a motor component which is mounted on an electric appliance for reciprocating motion.

[Please refer to the first figure] for the structure of the conventional solenoid valve (1), the solenoid valve (1) has a passage (11) inside, and the passage (11) is surrounded by a large number of conductive coils (12), and the passage (11) Inside, there is a telescopic body (13) which is made of a material that can be magnetized, whereby the conductive coils (12) are energized when the conductive coils (12) are energized. The magnetic field in the channel (11) is attracted to the expandable body (13), and [see also the second figure], and the action of the expansion/contraction (13) is achieved by the on/off mode.

However, in order to have sufficient magnetic attraction, the periphery of the passage (11) must surround a relatively large number of coils (12), which causes an increase in the overall volume and weight of the solenoid valve (1), as well as an increase in cost.

In view of the above-mentioned shortcomings, the inventor believes that it has the urgent need to make corrections, and that it has been engaged in the design and manufacture of related products for many years, and has always adhered to the excellent design concept, and researched and created the above disadvantages. After continuous efforts, the upper and lower telescopic solenoid valves of the present invention were finally introduced, which improved the efficiency of the product by correcting the excellent product structure.

SUMMARY OF THE INVENTION A primary object of the present invention is to provide an improved solenoid valve structure which has the disadvantages of increased volume and weight caused by a large number of coils and high cost.

In order to achieve the foregoing object, the upper and lower telescopic solenoid valve of the present invention comprises a covering member and a telescopic member, and the covering member is composed of a covering body, a coil and a telescopic hole, and the periphery of the covering body surrounds There are some coils, and the covering body is internally provided with a telescopic hole for the upper and lower displacement of the telescopic member, and the telescopic member is composed of a housing and a magnetic block, and the magnetic block is installed in the housing. And the magnetic block is a magnet.

Therefore, since the magnetic block in the telescopic member can enhance the magnetic attraction effect of the magnetic field generated by the coil, the number of coils for generating the magnetic field can be reduced, which further reduces the volume and weight of the electromagnetic valve itself, and also reduces the use of the coil. Cost problem.

The invention relates to an up-and-down telescopic solenoid valve, [see the third figure] mainly comprising: a covering member (2), mainly consisting of a covering body (21) and a coil (22) And a telescopic hole (23), the periphery of the covering body (21) is surrounded by a plurality of coils (22), and the covering body (21) is internally provided with a telescopic hole (23), and the telescopic hole (23) The lower part is defined as an outlet (231), and the telescopic hole (23) and the outlet (231) are for upper and lower displacement expansion and contraction of a telescopic member (3); the telescopic member (3) is mainly composed of a housing (31) The magnetic block (32) is composed of a magnetic block (33) which is made of a material that cannot be magnetized (for example, plastic, wood), and the housing (31) is built in A magnetic block (32) and a magnetic block (33) having the same size are provided, and since the magnetic block (32) is the same size as the magnetic block (33), a stable magnetic field can be provided to stabilize the magnetic influence force. The magnetic block (32) is attached to the magnetic block (33), the magnetic block (32) is a magnet, and the magnetic block (33) is made of a magnetic material (eg copper, iron). )By.

The upper and lower telescopic solenoid valve of the present invention (see the third figure) is in a state of being energized. In this state, the energized coil (22) generates a magnetic field in the telescopic hole (23) to further have a magnetic block ( 32) The telescopic member (3) of the magnetic block (33) is attracted to the telescopic hole (23), and conversely, [see the fourth figure], the system is in an unenergized state, and in this state, the telescopic hole (23) There is no force to attract the telescopic member (3), and therefore, the telescopic member (3) is displaced to the outside of the outlet (231).

The upper and lower telescopic solenoid valve of the present invention has the advantage that a combination of a magnetic block (32) and a magnetic block (33) is provided in the telescopic member (3), wherein the magnetic block (32) can enhance the coil (22) The magnetic attraction effect of the magnetic field is generated. In contrast, the number of turns of the coil (22) for generating the magnetic field can also be reduced, thereby reducing the solenoid valve. The volume and weight of itself also reduce the cost.

The upper and lower telescopic solenoid valve of the present invention, [see FIG. 5 and FIG. 6] can directly mount a single magnetic block (32) in the casing (31) of the telescopic member (3), which can also achieve the above effects. .

In summary, it is understood that the present invention is novel, and the present invention is not found in any publication, and is in compliance with the provisions of Articles 21 and 22 of the Patent Law.

The above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto. That is, the equivalent changes and modifications made by the invention in accordance with the scope of the invention are still within the scope of the invention.
