Abstract
The utility model discloses an improvement of a water pump for use in a foot batch tub, which comprises a pump body consisting of an upper shell, a middle shell and a lower shell, and a magnetic coil is arranged in a cavity formed by the middle shell and the lower shell after being installed; and a rotor and an impeller which is connected with the rotor are arranged in a cavity formed by the upper shell and the middle shell after being installed, and the rotor and the impeller are installed on a rotor shaft. The utility model is mainly characterized in that the rotor shaft is uni-directionally fixed on the middle shell. The rotor shaft is uni-directionally fixed, therefore, no exposed part exists, and no hair is entangled on the rotor shaft, thereby ensuring the service life.
Description
Technical field
The utility model relates to the improvement invention of the water pump of using in a kind of lavipeditum dish.
Background technique
In the prior art, it is very universal that the lavipeditum dish is used for foot health-care, and also entered ordinary citizen house, therefore, the quality problems user of lavipeditum dish particularly has been concerned about, existing lavipeditum dish, its rotor all is that two ends are fixing, and the one end is fixed on mesochite and puts, and the other end is fixed on the upper shell, therefore, rotor shaft can be long, wherein has one section can expose, and invade for a long time and duck in drink, when the long-term lavipeditum of lavipeditum person, fine hair on the pin can be entangled with in this extending part, and the user is still unaware, and is so long-term, run up to a certain degree, can influence wheel rotation and have influence on life-span of rotor; Also have one to be exactly, rotor and impeller turn round on rotor shaft for a long time because and the rotor shaft contacting point be working of plastics, therefore wearing and tearing can occur, and in case occur wearing and tearing, wheel rotation can be waved, and also can influence the normal use of lavipeditum dish; Another is exactly, and there is a seal ring upper shell and middle valve jacket installation place, is to be set directly at two valve jacket joints, and when therefore installing, the position will have influence on sealability in case skew occurs, also can make the user in use have potential safety hazard.
Summary of the invention
In view of the existing technical problem of background technique, it is good that technical problem to be solved by this invention provides a kind of sealability, and running is steady, the water pump of using in a kind of foot bath of long service life.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: the water pump that this kind used in the lavipeditum dish, comprise the pump housing, the described pump housing is made of the upper, middle and lower valve jacket, in the cavity that forms after valve jacket and lower shell are installed in described electromagnetic coil is set, described upper shell and middle valve jacket are installed the impeller that is provided with rotor and is connected with rotor in the cavity that the back forms, described rotor and impeller are installed on the rotor shaft, it is characterized in that the unidirectional mesochite that is fixed on of described rotor shaft puts.
Described impeller and internal rotor are provided with a wear-resistant sleeve, and impeller and rotor are installed on the rotor shaft by wear-resistant sleeve.
Described wear-resistant sleeve adopts thermoplastic polyurethane material (PTU) to make.
Be provided with gland in the cavity that forms after described upper shell and middle valve jacket are installed, be provided with the step that matches with gland in the described upper shell, described gland bottom is provided with seal ring, and described mesochite puts the retaining ring that is provided with restriction upper shell housing distortion.
The beneficial effects of the utility model are: rotatingshaft is carried out unidirectional fixing, therefore do not have exposed portions serve, just do not have hair and be not entangled with on rotatingshaft, guaranteed working life.Owing to be provided with the PTU wearing layer at impeller and internal rotor, can guarantee that therefore wearing and tearing can not appear in rotor and impeller in the long-term operation process.The form that adopts gland to cooperate with the upper shell step, in installation process, because step can withstand gland, gland presses down simultaneously and can exert pressure to seal ring, at this moment, seal ring can expand, and therefore can effectively guarantee its sealability, and the retaining ring that mesochite puts then can limit upper shell and prevent housing distortion in installation process.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is the prior art structural representation;
Fig. 2 is the utility model structural representation.
Embodiment
Accompanying drawing has been represented structure of the present utility model and embodiment, further describe the relevant details of embodiment below more in conjunction with the accompanying drawings, the water pump that this kind used in the lavipeditum dish, comprise the pump housing, the described pump housing is made of the upper, middle and lower valve jacket, in the cavity that valve jacket 5 forms after installing with lower shell 10 in described electromagnetic coil 8 is set, described upper shell 3 is installed the impeller 2 that is provided with rotor 4 and is connected with rotor 4 in the cavity of back formation with middle valve jacket 5, described rotor 4 and impeller 2 are installed on the rotor shaft 1, described rotor shaft 1 unidirectional being fixed on the middle valve jacket 5.
Described impeller 2 is provided with a wear-resistant sleeve 7 with rotor 4 inside, and impeller 2 and rotor 1 are installed on the rotor shaft 1 by wear-resistant sleeve 7.
Described wear-resistant sleeve 7 adopts thermoplastic polyurethane material (PTU) to make.
Be provided with gland 9 in the cavity that described upper shell 3 forms after installing with middle valve jacket 5, be provided with the step 11 that matches with gland 9 in the described upper shell 3, described gland 9 bottoms are provided with seal ring 6, and described middle valve jacket 5 is provided with the retaining ring 12 of restriction upper shell 3 housing distortions.
Rotatingshaft is carried out unidirectional fixing, therefore do not have exposed portions serve, just do not have hair and be not entangled with on rotatingshaft, guaranteed working life.Owing to be provided with the PTU wearing layer at impeller and internal rotor, can guarantee that therefore wearing and tearing can not appear in rotor and impeller in the long-term operation process.The form that adopts gland to cooperate with the upper shell step, in installation process, because step can withstand gland, gland presses down simultaneously and can exert pressure to seal ring, screw continues fastening, and at this moment, seal ring can expand, therefore can effectively guarantee its sealability, the retaining ring that mesochite puts then can limit upper shell and prevent housing distortion in installation process.
