Description
Technical field
The utility model relates to the machine equipment field that cleans one's teeth, and is specifically related to a kind of machine novel piston blowback water device that cleans one's teeth.
Background technique
The family expenses machine that cleans one's teeth generally is made up of 3 parts, water source, pumping, support and shower nozzle; Pumping utilizes the principle of pulse pump, relies on the reciprocating motion of the pistons in the motor driving pump cylinder, produces pressure reduction, extracts water purification from the water source or is mixed with the water of medicine; And from the shower nozzle ejection, because the working principle of pulse pump, the water of ejection is the impulse type globule, and its pulse frequency is by the design decision of pumping; This device is used for daily tooth and oral cleaning, can effectively safeguard dental health, the treatment periodontosis.
In traditional pulse pump structure, controlled water flow inlet valve and outlet valve arranged, in the work, by the reciprocating motion of the pistons of driven by motor; Inlet valve is opened when a lateral movement, and outlet valve closes, and water flows in the cylinder body, when piston moves to opposite side; Outlet valve is opened, and inlet valve closes, and current are forced out, owing to adopt the single cylinder structure; Through the regulating piston rotating speed, current spray with the form of pulsation, but owing to reason mentioned above, when suspending water spray; Current are blocked, and do not have decompressor simultaneously, can cause the pump housing and motor overload.Therefore, the product on the market is once restriction service time all, generally do not allow to surpass 3-5 minute, and for 2 people of family or above use, very inconvenience.
The model utility content
The problem that the utility model will solve provides a kind of novel reciprocating pump water recovery apparatus; With the cost of minimum in indoor design decompressor, need not add decompression or shunting device, when current are blocked at the tooth cleaner handgrip place; Can in the pump housing, not accumulate pressure; But pass back into tank, and thoroughly solve overload, prolong machine working life.
For addressing the above problem; The utility model is realized through following scheme: a kind of machine novel piston blowback water device that cleans one's teeth; It comprises water pump body and connecting rod, and said water pump body includes water nozzle, water outlet, piston, saidly goes into water nozzle and is installed on the water pump body through two retaining screws; In the water pump body set inside check valve body and one-way valve are arranged; This check valve body is connected with one-way valve, is provided with spring and backwater valve ball in the said check valve body, and this backwater valve ball is blocked on the check valve body backwater hole by spring force.
Said water pump body and go into also to be provided with seal ring between the water nozzle.
Said one-way valve is near going into water nozzle, this one-way valve edge with go into water nozzle and leave crack.
Said connecting rod one end and piston interconnect, and the other end connects drive motor.
The utility model has solved in the middle of using, and when needing the nozzle current to suspend because of use, motor that causes and water pump overload and consequent heating damage; The bypass design that does not need simultaneously the water route, water recovery apparatus all in water pump body, integrated design; Need not use other couplings or diversion member; Assembly is minimum, has lowered manufacture cost, has guaranteed the pocket structure of product.

Fig. 2 is the utility model sectional view;
Fig. 3 is the utility model embodiment schematic representation.
Embodiment
Below be to combine embodiment and description of drawings that the utility model is done further description:
Like Fig. 1, shown in Figure 2, a kind of machine novel piston blowback water device that cleans one's teeth, it comprises water pump body 12 and connecting rod 11; Said water pump body 12 includes water nozzle 1, water outlet 8, piston 10, saidly goes into water nozzle 1 and is installed on the water pump body 12 through two retaining screws 9, in water pump body 12 set inside check valve body 4 and one-way valve 2 is arranged; This check valve body 4 is connected with one-way valve 2; Be provided with spring 5 and backwater valve ball 7 in the said check valve body 4, this backwater valve ball 7 is blocked on check valve body 4 backwater holes 13 by spring 5 elastic force, water pump body 12 and go into also to be provided with seal ring 6 between the water nozzle 1; One-way valve 2 is near going into water nozzle 1; These one-way valve 2 edges with go into water nozzle 1 and leave crack, connecting rod 11 1 ends and piston 10 interconnect, the other end connection drive motor 17.
Embodiment: like Fig. 2, shown in Figure 3; When water pump is started working, drive piston 10 translations to the right by drive motor 17 drive link 11, when current through going into water nozzle 1 and one-way valve 2 marginal flows are gone in the water pump body 12; In next stroke; Drive motor 17 drive link 11 drive piston 10 translations left, and the reason that this moment, one-way valve 2 was under pressure moves up and blocks current direction and go into water nozzle 1 and flow; Thereby current flow out from water outlet 8, and backwater valve ball 7 is in backwater hole 13 states of blocking always in this working procedure.
When water outlet 8 is plugged (because use needs), along with the continuous to-and-fro motion of drive motor 17 drive link 11 drive pistons 10, water pump body 12 internal pressures increase gradually; After arriving certain pressure; Promote backwater valve ball 7 extrusion springs 5, the thrust that the elastic force of spring 5 produces less than pressure, then backwater valve ball 7 moves up; This moment, backwater hole 13 was opened, and current turn back in the water tank from going into water nozzle 1 through back-water valve (BWV) outlet 3.
Act between elastic force through backwater valve ball 7 and spring 5 and the pressure, kept the upper limit of pressure maximums in the water pump body 12, protected the complete work of water pump, and the setting of this pressure maximum can be selected to reach through elastic force size to spring 5.
