Abstract

The utility model relates to an air pump for fish bowls. One end of a vibration cap of compressed air in the air pump is glidingly sheathed on a charging valve seat of the air pump; the other end and a vibration arm are locked into a whole. The vibration cap is made of teflon or silica gel. The proper position of a box body of the air pump is provided with a pushing block which is bunted on the vibration arm. The structure can cause the air pump to generate compressed air more effectively and prevent the air pump from generating the negative pressure of the return air and destroying the vibration cap caused by the jam of a wind outlet, and therefore, the service life of the vibration cap is extended.

Description

Air pump for fish bowls

The utility model is relevant fish jar air pump, and particularly at the structure of air pump internal vibration cap, the phase makes air pump produce more efficient compressed air, and prolongs the service life of vibration cap.

The air pump of commonly using as shown in Figure 1, mainly lies in the box body 1, installs one group of solenoid 11; One or the two inlet valve seat 12(that are fixed in solenoid 11 the place aheads are illustrated as two inlet valve seats); Be hubbed at the vibrating arm 13 of valve seat 12 sides, these vibrating arm 13 front ends are fixed with magnet piece 131, and mat solenoid 11 attraction magnet pieces 131, and make each vibrating arm 13 do double vibrations; And the moving cap 14 of the rubber damping that is locked in vibrating arm 13 stage casings respectively, the flange 141 that the other end mat of this vibration cap 14 is inwardly stretched, be held in the groove 121 of inlet valve seat 12, so that the vibration cap 14 that this end is fixed must be with the double vibrations of vibrating arm 13, and the air in the compression valve seat air chamber 122, make compressed air follow the closed orbit roads in the valve seat 12 and arrange Bubbled stone in being loaded on fish jar, soluble in water again.All hobbies are cultured the personage of pet fish with fish jar, know that all air pump used about 1 year, be rubber vibration cap 14 aging crackings of Yin Qinei, and whole replacing of need, studying carefully its senile cause has two, the dysplasia that one combines with air inlet seat 12 for vibration cap 14, and another is then not good for the material that vibration cap 14 is adopted, and these two factors more influence each other, and quicken the aging cracking of vibration cap 14; Lid, the vibration cap 14 of rubber system are corroded by contained acidity or alkaline matter can in air or the water, and aging cracking gradually, and existing or the vibration cap 14 of aging phenomenon is not arranged as yet, again because of being in the situation that repetitiousness is stretched and compresses for a long time, more quicken its degree of aging.Again, we all know, water in the fish jar is because of the effect of impurity in the excreta of feed, fish and the air, and generation algae, floating material and inorganic matter, the very easily attached work of these algae, floating material and inorganic matter is on Bubbled stone surface and result in blockage, the Bubbled stone surface is in case blocked, and the compressed air in the valve seat 12 promptly forms the return air back pressure to vibration cap 14, and the vibration cap 14 of the rubber system of tearing.

The purpose of this utility model provides a kind of air pump and vibration cap thereof of novel structure.

The air pump that provides according to the utility model, wherein: the vibration cap of this air pump, be that an end locks on the vibrating arm admittedly, the other end then sliding sleeve on the inlet valve seat of air pump, so that the vibration cap is when compressed air, itself be to become the slidingtype advance and retreat, and do not have suffered the pullling or pushing of fixed vibration cap, so be difficult for breaking with vibrating arm.

The air pump that provides according to the utility model, wherein: the vibration cap of this air pump, be with have prevent in the air or fish jar water in contained acidity or the alkaline matter Teflon or the silica gel that corrode made, to prolong the service life of vibration cap.

Now cooperate graphicly, the preferred embodiment of the utility model be described as follows:

Fig. 1 is for commonly using fish jar air pump assembled sectional view;

Fig. 2 is the utility model fish jar air pump assembled sectional view.

1: box body 11: solenoid 12: inlet valve seat

121,121 ': valve seat groove 122: valve seat air chamber

13: vibrating arm 131: magnet piece 14: the vibration cap

141: flange

21: vibration cap 22: jacking block

As shown in Figure 2, the air pump of the utility model lies in the box body 1, installs one group of solenoid 11; One or the two inlet valve seat 12(that are fixed in solenoid 11 the place aheads are illustrated as two inlet valve seats); Be hubbed in the vibrating arm 13 of valve seat 12 sides, the magnet piece 131 that its front end of mat is fixing is subjected to the attraction of solenoid 11, and makes each vibrating arm 13 do double vibrations (above all elements are roughly the same with the person of commonly using); Reach the vibration cap 21 that is locked in vibrating arm 13 stage casings respectively, this vibration cap 21 is made as good with tool acid-resisting, alkaline attack and oxidation resistant Teflon or silica gel, and vibration cap 21 is that this is principal character of the present utility model to direct sliding sleeve in inlet valve seat 12(), because of vibration cap 21 need not to be held in the groove 121 of inlet valve seat 12,, its metastomium periphery do not appoint the flange that closes projection so having; Promptly be subjected to the effect of solenoid 11 when vibrating arm 13, when being the air in the direct promotion vibration cap 21 inside compression valve seat air chambers 122, vibration cap 21 itself directly is not squeezed; When vibrating arm 13 drove the outside diastole of vibration cap 21, vibration cap 21 was not also directly pullled, so can prolong the life-span of vibrating cap 21.Again, box body 1 is interior in the appropriate location of vibrating arm 13, more must be provided with the rubber or the silica gel jacking block 22 that are resisted against vibrating arm 13, this rubber of mat or silica gel jacking block 22, holding of this rubber of mat or silica gel jacking block 22, make the stroke of vibrating arm 13, do not cause vibration cap 21 to break away from inlet valve seats 12, to strengthen vibration cap 21 compressed-air actuated efficient in outside diastole.Moreover, groove 121 on this inlet valve seat 12 ' be to be positioned at slightly outer fix of inlet valve seat 12, make Bubbled stone in case stop up, and when causing compressed-air actuated return air back pressure, this compressed air still can be overflowed by the gap that groove 121 ' locate or vibrate cap 21 combines with inlet valve seat 12, and can not tear vibration cap 21.

Therefore, the utlity model has following advantage;

1. mat vibration cap sliding sleeve is in the structure of inlet valve seat, make the vibration cap when double vibrations, fixed suffered compression in no both sides own or stretching, the driving stroke of vibration cap is strengthened, to increase the discharge pressure of fan of air pump, and can prevent tearing of compressed air return air back pressure, to prolong its service life.

2. the mat vibration special substance that cap adopted makes the vibration cap no longer be subjected to the erosion of contained chemical substance in fish jar water or the air, and can fit in and do sagittal slip on the inlet valve seat.

3. the interior jacking block of mat box body is held in the structure of vibrating arm, makes vibrating arm drive cap more efficiently and moves reciprocatingly.

In sum, the utility model repeatedly compares with air pump with existing many moneys fish jar through the inventor, confirms really can improve service life and the compressed-air actuated efficient of fish jar with air pump, and apply for a patent in accordance with the law the whence.
