Description

Technical Field

[0001] The present invention relates to the technical field of electromagnetic pumps, and more particularly to an anti-sticking electromagnetic pump with a striker. Background Art

[0002] The basic working principle of an electromagnetic pump in the prior art is as follows: First, a magnetic field is generated by an electromagnetic coil, and rectified by a diode. When powered on, during the positive half-cycle, the piston moves towards the water inlet, compresses the main spring, and sucks in liquid; during the negative half-cycle, the coil is powered off, the main spring is released, and the piston is pushed towards the water outlet direction. By this way, it continuously makes reciprocating motions. When the pressure is greater than the sealing pressure of the internal check valve and the rubber plug of the outlet check valve, the liquid flows out from the water outlet.

[0003] The above-mentioned type of electromagnetic pump mainly relies on two check valves to complete the process of vacuum pumping water. Since the amount of water stored in the electromagnetic pump is very small, if it is not used for a relatively short period of time, the water in the cavity will evaporate. During the evaporation process, the water will contain dead bacteria, making the residue sticky. Such a sticky substance will tightly stick the rubber plug of the check valve and the sealing position of the water outlet pipe. If there is water in the electromagnetic pump cavity, a relatively large pressure can be generated to push open the stuck rubber plug of the check valve. However, since the water in the electromagnetic pump has completely evaporated at this time, the pressure generated by the electromagnetic pump pumping air is relatively low, and the pressure generated by the electromagnetic pump cannot be used to push open the check valve, thus causing the water pumping function of the electromagnetic pump to fail. Summary of the Invention

[0004] The present invention provides an anti-sticking electromagnetic pump with a striker for the problems of the prior art, by adding an anti-sticking member, which is used to strike the liquid outlet unit so that the liquid outlet unit will not stick at the liquid outlet, thereby maintaining the normal use of the water pumping function of the electromagnetic pump.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: An anti-sticking electromagnetic pump with a striker, comprising an electromagnetic assembly, a liquid inlet assembly, and a liquid outlet assembly.

Specific embodiments

[0023] For the convenience of understanding by those skilled in the art, the present invention will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the embodiments is not a limitation to the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0024] A kind of anti-adhesion electromagnetic pump with an ejector pin provided in this embodiment, as Figures 1 to 3 shown, includes an electromagnetic component, a liquid inlet component, and a liquid outlet component. The liquid inlet component includes a liquid inlet pipe 5, the liquid inlet pipe 5 is installed on the electromagnetic component, the liquid inlet pipe 5 is provided with a liquid cavity 6, a piston 7 is installed in the liquid cavity 6, and the piston 7 is slidably connected to the cavity wall of the liquid cavity 6. Among them, the structural settings of the electromagnetic component and the liquid inlet component in this embodiment are all prior arts; and the liquid outlet component includes a liquid outlet pipe 8, a first rubber plug 9, a liquid outlet unit, and an anti-adhesion member 10. The liquid outlet pipe 8 is installed on the electromagnetic component and is communicated with the liquid cavity 6. The first rubber plug 9, the liquid outlet unit, and the anti-adhesion member 10 are all installed in the liquid outlet pipe 8; as Figure 3 shown, a liquid outlet 11 is provided in the liquid outlet pipe 8, the liquid outlet unit is movably arranged outside the liquid outlet 11, that is, on one side close to the pipe orifice of the liquid outlet pipe 8. The liquid outlet unit is used to open or seal the liquid outlet 11. As Figure 2 shown, during the process of the liquid outlet unit moving in the liquid outlet pipe 8, when pumping water, the liquid outlet unit leaves the liquid outlet 11, and the liquid can be pumped out through the liquid outlet 11. When pumping water is not required, the liquid outlet unit resets to the liquid outlet 11 and fits with the liquid outlet 11 to block the liquid outlet 11.

[0025] Optionally, as Figure 2 , the liquid outlet unit includes a fixing plug 18, a second reset member 19 and a second rubber plug 20. The fixing plug 18 is installed at the nozzle of the liquid outlet pipe 8. The second rubber plug 20 is movably arranged between the liquid outlet 11 and the fixing plug 18. The second rubber plug 20 is used to block or open the liquid outlet 11. Two ends of the second reset member 19 respectively abut against the second rubber plug 20 and the fixing plug 18. Optionally, the second reset member 19 is a spring.

[0026] Specifically, in the prior art, during the process of the second rubber plug 20 of the liquid outlet unit fitting and blocking the liquid outlet 11, it may be in contact with the liquid outlet 11, resulting in the inability to pump water. When the electromagnetic pump pumps water, during the process of the liquid outlet unit gradually adhering to the liquid outlet 11, the resistance of water increases, the stroke of the piston 7 becomes smaller, and the first rubber plug 9 will not contact the liquid outlet unit. When the moisture in the electromagnetic pump cavity evaporates, the liquid outlet unit will stick to the liquid outlet pipe 8, resulting in the malfunction of the water pumping function. Therefore, in this embodiment, an anti-adhesion member 10 is additionally provided inside the liquid outlet 11, as shown in Figures 2 to 4 . The anti-adhesion member 10 has elasticity, such as silica gel, rubber, plastic, etc. After being fixed in the liquid outlet pipe 8, the anti-adhesion member 10 can also move. The first rubber plug 9 reciprocates between the piston 7 and the anti-adhesion member 10. When the electromagnetic pump operates, the air resistance in the liquid cavity 6 is small, and the stroke of the piston 7 will increase, causing the piston 7 to push the anti-adhesion member 10. The anti-adhesion member 10 impacts the liquid outlet unit, and the anti-adhesion member 10 is used to push open the second rubber plug 20, enabling the electromagnetic pump to resume the normal water pumping function. Therefore, in this embodiment, the anti-adhesion member 10 is used to prevent the second rubber plug 20 from adhering to the liquid outlet 11. After long-term use, the water pumping function of this embodiment can still be used normally. In addition, the connection structure of the connecting piece 14 with the striker 13 and the fixing ring 12 forms a through hole 15, which can ensure the flow of liquid.

[0027] Among them, as Figure 4 shown, the anti-adhesion member 10 includes a fixing ring 12, a striker 13 and a connecting piece 14. The striker 13 is connected to the fixing ring 12 through the connecting piece 14. A through hole 15 for liquid flow is formed among the fixing ring 12, the connecting piece 14 and the striker 13. The fixing ring 12 is installed in the liquid outlet pipe 8. The striker 13 is used to contact the liquid outlet unit and the first rubber plug 9. Further, the liquid outlet pipe 8 is provided with an annular groove 16, and the fixing ring 12 is assembled in the annular groove 16.

[0028] Specifically, the striker 13 is set as a columnar structure with a certain length and is then connected to the fixing ring 12 through the connecting piece 14. Therefore, as Figure 2As shown, when the striker 13 is subjected to the upward thrust of the first rubber plug 9, the striker 13 can move upward, i.e., generate movement, and strike the second rubber plug 20. When the electromagnetic pump operates normally, the air resistance in the liquid chamber 6 is small, and the operating stroke of the piston 7 will increase. The piston 7 pushes the first rubber plug 9 to move, and the first rubber plug 9 then strikes the striker 13, and the striker 13 strikes the second rubber plug 20 again, thereby preventing the second rubber plug 20 from sticking to the liquid outlet 11. The striker 13 increases the moving stroke of the first rubber plug 9, thereby helping to open the second rubber plug 20; even if the second rubber plug 20 sticks to the liquid outlet 11, under the single or multiple strikes of the striker 13, the second rubber plug 20 can also be separated from the liquid outlet 11, ensuring the normal operation of the water pumping function of this embodiment.

[0029] Among them, in order to enable the first rubber plug 9 to accurately return to the outlet of the piston 7 after moving and enable the anti-adhesion member 10 to be fixed at the liquid outlet 11, a first reset member 17 is installed in the liquid outlet pipe 8 in this embodiment. As Figure 2 shown, both ends of the first reset member 17 are in contact with the first rubber plug 9 and the anti-adhesion member 10 respectively. The first reset member 17 can be selected as a spring. After the first rubber plug 9 moves, the elastic force of the first reset member 17 can reset the first rubber plug 9, further enabling the water pumping function of this embodiment to continue to operate normally.

[0030] To improve the sealing performance of the electromagnetic pump in this embodiment, as Figure 2 shown, the liquid outlet assembly further includes a first sealing ring 21. The first sealing ring 21 is sleeved on the outer periphery of the liquid outlet pipe 8, and the first sealing ring 21 is located at the connection between the liquid inlet pipe 5 and the liquid outlet pipe 8. Specifically, the first sealing ring 21 can improve the sealing performance between the liquid outlet pipe 8 and the liquid inlet pipe 5, preventing water leakage and other situations.

[0031] Furthermore, the liquid outlet assembly further includes a second sealing ring 22. The second sealing ring 22 is located between the piston 7 and the liquid outlet pipe 8, thereby improving the sealing performance during the movement of the piston 7.

[0032] A non-sticking electromagnetic pump with a striker provided in this embodiment, as Figure 3 shown, a third reset member 23 is installed in the liquid chamber 6. Optionally, the third reset member 23 is a spring. The third reset member 23 is used to reset the piston 7 after it moves. Third reset members 23 are provided at both ends of the piston 7 to ensure that the piston 7 can accurately return to its position. The structure of the piston 7 is prior art.

[0033] A non-sticking electromagnetic pump with a striker provided in this embodiment, as Figure 2 and Figure 3, The electromagnetic component includes a housing 1, a coil 2, and a ferromagnetic bracket. The coil 2 is wound around the outer periphery of the ferromagnetic bracket. Both the coil 2 and the ferromagnetic bracket are assembled inside the housing 1, and the liquid inlet pipe 5 is assembled inside the ferromagnetic bracket. Optionally, the ferromagnetic bracket includes a plastic ring 3 and two iron rings 4 respectively installed at both ends of the plastic ring 3. The plastic ring 3 and the two iron rings 4 are connected to form a cylinder. Specifically, the electromagnetic function of this embodiment is prior art. The coil 2 is sleeved outside the iron ring 4, and an electric current is applied to generate a magnetic field, thereby controlling the movement of the piston 7.

Although the present invention is disclosed above in a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, when making some changes or modifications using the above-disclosed technical content to equivalent embodiments of equivalent changes, but as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change, and modification made to the above embodiments according to the technical means of the present invention shall fall within the scope of the technical solution of the present invention.
