Claim:
1. An interproximal squirt brush, comprising: a solution container having a solution chamber for containing a solution and a hollow nozzle head having an opening communicating with said solution chamber, wherein a resilient channel is aligned with said opening; and a brush head having an elongated retention portion replaceably coupling at said opening of said nozzle head and a brush portion extended from said retention portion, wherein a clearance is formed between said opening and said retention portion of said brush head for enabling said solution from said solution chamber being discharged to said brush portion of said brush head along said retention portion, wherein when said retention portion of said brush head is disposed along said resilient channel, an inner wall of said resilient channel is slightly deformed to define said clearance therebetween, wherein said solution container comprises an elastic latch provided at said nozzle head for detachably locking said retention portion of said brush head in position, wherein said resilient channel is defined at said elastic latch to align with said opening, wherein said elastic latch further has a resilient cavity and a latch cavity, wherein said elastic latch comprises a holding member defining said resilient channel therealong, and a locking member having one flexible edge integrally extending from said holding member and an opposed locking edge detachably coupling with said locking member to retain said retention portion of said brush head along said resilient channel, wherein said resilient cavity is provided at said holding member close to said flexible edge of said locking member, wherein said latch cavity is provided at a sidewall of said holding member and arranged in such a manner that when said locking member is folded on said holding member to engage said locking edge with said latch cavity, said resilient cavity is slightly deformed to apply an resilient force at said locking edge of said locking member so as to substantially lock up said locking member with said holding member.
