The first embodiment of the electromagnetic pump of the present invention is provided with a high output efficiency that can solve the above technical problems.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a first embodiment of an electromagnetic pump with high efficiency output according to the present invention.
In the drawings, elements having similar structures are denoted by the same reference numerals.
The invention provides an electromagnetic pump with high-efficiency output, which comprises a coil assembly 11, a pump pipe 13, an iron core 12, a return spring 14, a liquid outlet control spring 18, a liquid inlet control spring 17, a liquid outlet rubber head 16 and a liquid inlet rubber head 15.

Wherein, the liquid inlet rubber head 15 is provided with a push rod 151 at one end close to the sealing cavity 131, and the push rod 151 extrudes the liquid outlet rubber head 16 to move away from the sealing cavity 131. When the electromagnetic pump is started, the ejector rod 151 rigidly extrudes the liquid outlet rubber head 16, so that the liquid outlet rubber head 16 can overcome adhesion resistance and is easy to open, and water is easily pumped out. When the dispensing glue head 16 is not adhered to other parts, the dispensing glue head 16 is gradually opened while the push rod 151 moves towards the dispensing glue head 16, so that the push rod 151 does not influence the normal operation of the dispensing glue head 16 under the condition.

The second embodiment of the electromagnetic pump of the present invention is provided with a high output efficiency that can solve the above technical problems as follows. The main difference between this embodiment and the first embodiment is that a self-suction structure is added to the electromagnetic pump in this embodiment, and it should be noted that the problem of adhesion between the dispensing glue head and other parts can also be solved by separately providing the self-suction structure. After the spring is used for a certain time, the elastic force can decline, and the extrusion force of the ejector rod can also correspondingly decline, so that the self-suction structure can be matched with the ejector rod to be used together, and the problems of adhesion of the liquid outlet rubber head and difficulty in pumping water can be solved. The same reference numerals are used for the same structures in this embodiment as in the first embodiment.
The embodiment provides an electromagnetic pump with high-efficiency output, which comprises a coil assembly 11, a pump pipe 13, an iron core 12, a return spring 14, a liquid outlet control spring 18, a liquid inlet control spring 17, a liquid outlet rubber head 16, a liquid inlet rubber head 15 and a self-suction structure 21.

Wherein, the liquid inlet rubber head 15 is provided with a push rod 151 at one end close to the sealing cavity 131, and the push rod 151 extrudes the liquid outlet rubber head 16 to move towards the direction far away from the sealing cavity 131.
The self-priming structure 21 comprises a branch pipe 211 and a sealing head 212, wherein a liquid guide hole 2111 penetrating along the axial direction is formed in the branch pipe 211, the liquid guide hole 2111 is communicated with the sealing cavity 131 and the external space, and the sealing head 212 is movably arranged in the branch pipe 211 and used for sealing the liquid guide hole 2111.
When the electromagnetic pump is started, the ejector rod 151 rigidly extrudes the liquid outlet rubber head 16, so that the liquid outlet rubber head 16 is easy to open, and water is easy to pump out. When the push rod 151 can not push the dispensing glue head 16 to move, air in the sealing cavity 131 can be discharged through the self-suction structure, so that water can easily enter the sealing cavity and soak the dispensing glue head, the adhesion force between the dispensing glue head 16 and other parts is small, the dispensing glue head 16 is easy to open, and water can be easily pumped out.
The self-priming structure 21 in this embodiment further includes a self-priming spring 213 and a spring seat 214, the spring seat 214 is connected to an end of the branch pipe 211 away from the pump pipe 13, and the self-priming spring 213 is disposed between the sealing head 212 and the spring seat 214. Meanwhile, the assembly and disassembly are convenient, and parts are replaced and utilized.
Referring to fig. 4, a clamping groove is disposed on the periphery of one end of the liquid outlet hole of the pump tube 13, the clamping groove can be used for being connected with a device at one end of the liquid outlet hole, a connecting hole 132 for being communicated with the self-suction structure 21 is disposed on the pump tube, and the connecting hole 132 is bent to avoid the clamping groove.
The pump pipe 13 is provided with a boss portion for screw-coupling with the branch pipe 211, and an external thread is provided on the outer peripheral side of the boss portion.
Referring to fig. 3, in the present embodiment, the branch pipe 211 is in threaded connection with the pumping pipe 13, the protruding ring 2112 is disposed on the periphery of one end of the branch pipe 211 away from the pumping pipe 13, the spring seat 214 includes a connecting shaft 2141 and a fastening portion 2142, the fastening portions 2142 are distributed around the connecting shaft 2141, one end of the connecting shaft 2141 is sleeved in the branch pipe 211, and the fastening portion 2142 is fastened to the protruding ring 2112, so that the connection is convenient.
Referring to fig. 2, two ends of the self-priming spring 213 in this embodiment are respectively sleeved with the sealing head 212 and the connecting shaft 2141, the spring seat 214 is provided with a communication hole 2143 for communicating the liquid guide hole 2111 with an external space, and when the sealing head 212 moves a set distance in a direction close to the spring seat 211, the sealing head 212 seals the communication hole 2143. That is, when the water pressure is higher, the water pressure can press the sealing head 212 to seal the communication hole 2143, so that the branch pipe 211 does not output water any more, the set distance in this embodiment is between 0.5 and 3mm, and a smaller set distance can be set, so that air leakage can be realized, but water leakage is not easy.
One end of the sealing head 212 is provided with a conical end portion for sealing the communication hole 2143, and an inner circumferential surface corresponding to an outer circumferential surface of the end portion is provided on an inner wall surface of the communication hole 2143.
In addition, the outer periphery of the other end of the sealing head 212 may be provided with a sliding contact protrusion (the sliding contact protrusion is not shown in the figure) for sliding contact with the inner wall surface of the branch pipe, so that the sealing head 212 can stably slide along the axial direction in the branch pipe 211, and is not easy to shake and more stable.
In this embodiment, the branch pipe 211 and the sealing head 212 are made of metal, and are not easy to adhere to each other, and the liquid guide hole 2111 may be communicated with the liquid inlet hole, so that the liquid guide hole 2111 is drained to one end of the liquid inlet hole when water leaks. When the sealing head 212 seals the liquid guiding hole 2111 and the liquid outlet glue head 16 seals the liquid outlet hole, the elastic force of the self-suction spring 213 is greater than that of the liquid outlet control spring 18, so that when the water pressure is low, water is more easily discharged through the liquid outlet hole, and the branch pipe 211 does not output water any more. It can be understood that when the dispensing head 16 is adhered to the pump tube 13, the elastic force of the adhesion force adding dispensing control spring 18 is larger than the elastic force of the self-absorption spring 213, and it is difficult to squeeze the dispensing head 16.
Alternatively, the spring seat 214 may be configured to be screwed with the branch pipe 211, so that the elastic pressing force of the self-suction spring 213 on the sealing head 212 may be conveniently adjusted by screwing the spring seat 214. However, the threaded connection has a disadvantage over the snap connection in that it requires a large number of rotations to connect the spring seat 214 and the branch pipe 211 to a certain extent, which is not convenient for disassembly and assembly.
The working principle of the electromagnetic pump with high-efficiency output is as follows: coil pack 11 circular telegram can produce magnetic field, and iron core 12 can receive magnetic force to influence and can compress reset spring 14 to the left end motion in the 1 position of this process seal chamber 131 volume can grow, and pressure can diminish, and head 15 is glued to the feed liquor is easily opened, balances seal chamber 131's pressure.
Then, because the alternating current is used, the coil assembly 11 can change from electrified to non-electrified, when the power is not electrified, the return spring 14 can reset and push the iron core 12 to the right end in fig. 1, the liquid inlet rubber head 15 is driven to compress the sealing cavity 131, meanwhile, the volume of the sealing cavity 131 is reduced, the pressure intensity is increased, the liquid outlet rubber head 16 is tightly sealed due to the fact that the liquid outlet rubber head 16 is adhered or one end of a water outlet hole has large back pressure, the ejector rod 151 moves towards the right along with the liquid inlet rubber head 15, the ejector rod 151 rigidly presses the liquid outlet rubber head 16, the liquid outlet rubber head 16 is easy to open, and water is easy to pump out.
When the push rod 151 fails to push the glue outlet head 16 open, the sealing head 212 is expanded to balance the pressure, the gas can be discharged from the liquid guide hole 2111 of the branch pipe 211, and the gas can be discharged by reciprocating operation.
Wherein, gas outgoing also can draw water simultaneously, hydroenergy gets into in the sealed chamber 131 to soak and go out liquid and glue head 16, make out the adhesion between liquid and glue head 16 and pump line 13 and reduce, go out liquid and glue head 16 and open easily, water is pumped out from going out the liquid hole very easily.
It should be noted that the water pressure in the seal chamber 13 will also press the seal head 212 to open, but the seal head 212 is limited by the spring seat 214, the stroke of the seal head 212 will be short, and the pressure in the seal chamber will be relatively high due to the large back pressure, so that the seal head 212 can be pressed to be relatively stably pressed against the communication hole of the spring seat 214, so that the branch pipe 211 can not output water any more.
This electromagnetic pump of high-efficient output of electromagnetic pump of preferred embodiment is through setting up from inhaling the structure for when the electromagnetic pump starts, the air of sealed intracavity can be through inhaling the structure discharge certainly, makes water enter into sealed chamber easily, and soaks out the liquid and glue the head, makes out the liquid and glue adhesion power between head and other parts little, goes out the liquid and glues the head and open easily, and water is pumped very easily.
In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, therefore, the scope of the present invention shall be determined by the appended claims.
