Description

Technical Field

[0001] This utility model belongs to the field of water pressure switch technology, specifically a water pressure switch for a fish bait drying device. Background Technology

[0002] Microwave dryers are widely used in drying and sterilizing fish bait. The working principle of a microwave dryer is that the magnetron generates microwaves after being energized with high voltage. The microwaves penetrate the material and cause the moisture in the material to evaporate. The magnetron generates a lot of heat when it is working and the temperature is high, so it needs to be cooled by circulating water. The cooling water is delivered by a pressurized water pump to cool the magnetron and ensure normal and stable operation.

[0003] If the cooling water pressure is insufficient or there is a lack of water, the magnetron will heat up rapidly, causing it to burst and resulting in mass damage to the magnetron. Water pressure switches can sense pressure changes to trigger circuit switching, thereby controlling the start and stop of pumps or microwave dryers. However, existing water pressure switches are usually exposed to the working environment and are easily subjected to impacts and dust and oil. In addition, traditional single water pressure switches can only detect water pressure at one point, which has limitations. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a water pressure switch for a fish bait drying device, which solves the problems that existing water pressure switches are usually exposed to the working environment, are easily subjected to collisions and dust and oil stains, and that traditional single water pressure switches can only detect water pressure at one point, which is a limitation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water pressure switch for a fish bait drying device, comprising a connecting pipe and an electronic water pressure switch, wherein the electronic water pressure switch is installed on the connecting pipe, one side of the electronic water pressure switch is connected to an electrical line, the other side of the electronic water pressure switch is connected to a control line and a connecting line, one end of the connecting line is connected to a secondary pressure sensor, a connector is installed below the connecting pipe, and a protective shell is installed on the connector by bolts;

[0006] A top cover is installed on the top of the protective shell, an observation window is installed on the protective shell, ear plates are connected to both sides of the protective shell, fastening bolts are threaded on the ear plates, multiple ventilation holes are opened on the top cover, a dustproof plate is connected to the bottom of the top cover, a motor is fixedly installed inside the top cover, and fan blades are installed on the output shaft of the motor.

[0007] As a further embodiment of this utility model: heat dissipation vents are provided on both sides of the protective shell, and a dustproof net is connected to the heat dissipation vents of the protective shell.

[0008] As a further embodiment of this utility model: both the connector and the lower part of the protective shell are arc-shaped and are in close contact with the surface wall of the connecting pipe. Both the connector and the protective shell have fixing holes of the same size.

[0009] As a further embodiment of this utility model: three limiting plates are connected below the top cover, and three limiting grooves are provided on the protective shell, with the limiting plates inserted into the limiting grooves.

[0010] As a further embodiment of this utility model: the power supply line, control line and connecting line are respectively arranged in three limiting grooves, and the lower end of the limiting plate is arc-shaped.

[0011] As a further embodiment of this utility model: threaded holes are provided on both sides of the top cover, and the fastening bolts are threadedly connected to the threaded holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This fish bait drying equipment uses a water pressure switch. It is constructed with connecting pipes, control lines, a secondary pressure sensor, connectors, a protective shell, and fixing holes. During connection, the connecting pipes are connected to the cooling water pump, the control lines are connected to the power switch on the microwave dryer's control panel, and the secondary pressure sensor is installed at the cooling water inlet of the magnetron. The electronic water pressure switch and the secondary pressure sensor detect the water pressure at the pump and the magnetron inlet, comparing the water pressure data in real time to ensure that cooling water actually reaches the magnetron. This avoids false pressure caused by pipe leaks or valve malfunctions, improving accuracy. If the pressure is insufficient, the control lines control the start and stop of the microwave dryer to prevent damage to the magnetron. Bolts are used to fix the connectors and protective shell to the connecting pipes, ensuring the protective shell covers the electronic water pressure switch, protecting it from damage and reducing dust accumulation.

[0014] 2. This fish bait drying equipment uses a water pressure switch. It is equipped with fastening bolts, threaded holes, a top cover, a motor, fan blades, and a dustproof plate. Operators push the top cover onto the protective shell, aligning the threaded hole with the fastening bolt. Then, by tightening the fastening bolt, the bolt is driven into the threaded hole, securing the top cover to the protective shell and preventing accidental fall. The motor is then started to rotate the fan blades, accelerating airflow inside the protective shell and preventing heat buildup that could affect the normal operation of the electronic water pressure switch. The dustproof plate blocks dust, reducing its entry and adhesion. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a water pressure switch for a fish bait drying device, including a connecting pipe 1 and an electronic water pressure switch 2. The electronic water pressure switch 2 is installed on the connecting pipe 1. One side of the electronic water pressure switch 2 is connected to an electrical line 3, and the other side is connected to a control line 4 and a connecting line 5. The electrical line 3, the control line 4, and the connecting line 5 are respectively set in three limiting grooves 21. The lower end of the limiting plate 20 has an arc-shaped design. The limiting grooves 21 limit the electrical line 3, the control line 4, and the connecting line 5. The arc-shaped design at the bottom of the limiting plate 20 can press and seal the limiting grooves 21, ensuring that the wires are threaded through while preventing dust from entering from the limiting grooves 21.

[0022] One end of the connecting wire 5 is connected to a secondary pressure sensor 6. A connector 7 is installed below the connecting pipe 1. Both the connector 7 and the protective shell 8 have an arc-shaped design and are in close contact with the surface of the connecting pipe 1. Both the connector 7 and the protective shell 8 have fixing holes 19 of the same size. By inserting bolts into the fixing holes 19 on the connector 7 and the protective shell 8, the connector 7 and the protective shell 8 are fixed to the connecting pipe 1, thus protecting the electronic water pressure switch 2.

[0023] A protective shell 8 is installed on the connector 7 by bolts. Heat dissipation vents 17 are provided on both sides of the protective shell 8. A dustproof net 18 is connected to the protective shell 8 at the heat dissipation vents 17. The heat dissipation vents 17 can ensure normal air circulation and avoid heat accumulation, while the dustproof net 18 can prevent dust from entering the protective shell 8 from the heat dissipation vents 17.

[0024] A top cover 9 is installed on the top of the protective shell 8. Three limiting plates 20 are connected below the top cover 9. Three limiting grooves 21 are opened on the protective shell 8. The limiting plates 20 are inserted into the limiting grooves 21. Through the insertion of the limiting plates 20 into the limiting grooves 21, it is convenient for the staff to position the top cover 9 and prevent tilting during installation.

[0025] An observation window 10 is installed on the protective shell 8. Ear plates 11 are connected to both sides of the protective shell 8. Fastening bolts 12 are threadedly connected to the ear plates 11. Threaded holes 22 are opened on both sides of the top cover 9. The fastening bolts 12 are threadedly connected to the threaded holes 22. Multiple ventilation openings 13 are opened on the top cover 9. A dustproof plate 14 is connected to the bottom of the top cover 9. A motor 15 is fixedly installed inside the top cover 9. Fan blades 16 are installed on the output shaft of the motor 15. The top cover 9 is fixed by screwing the fastening bolts 12 into the threaded holes 22. The operation is simple and convenient for the staff to install and disassemble. The observation window 10 allows the staff to easily observe the data of the electronic water pressure switch 2.

[0026] The working principle of this utility model is as follows:

[0027] In the specific connection process, connect pipe 1 to the cooling water pump, connect control line 4 to the power switch of the microwave dryer control panel, and install the auxiliary pressure sensor 6 at the cooling water inlet of the magnetron. This allows the electronic water pressure switch 2 and the auxiliary pressure sensor 6 to detect the water pressure at the pump's cooling water outlet and the magnetron's cooling water inlet, comparing the water pressure data in real time to avoid situations where the pump outlet pressure is normal but the inlet pressure is low, thus improving accuracy. If the pressure is insufficient, the control line 4 transmits a signal to control the start and stop of the microwave dryer. Then, the connector 7 and the protective shell 8 are combined together with bolts and installed and fixed on the connecting pipe 1. The top cover 9 is then pushed into the protective shell 8, and the fastening bolt 12 is tightened to make it enter the threaded hole 22, thus fixing the top cover 9 to the protective shell 8. This causes the protective shell 8 to cover the electronic water pressure switch 2, thereby protecting the electronic water pressure switch 2. Meanwhile, the motor 15 can rotate the fan blade 16 to accelerate the air circulation inside the protective shell 8 and prevent heat buildup inside the protective shell 8 from affecting the normal operation of the electronic water pressure switch 2.
