Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1 and 2, embodiment 1 of the present invention discloses an atomizing pump head, which includes a pump head body 10 and a nozzle 20 fixedly connected thereto, wherein an outlet of the pump head body 10 is tightly and fixedly connected to an inlet of the nozzle 20 to form a seal. The part of the pump head body 10 connected to the nozzle 20 is a first joint 11, and the part of the nozzle 20 connected to the first joint 11 is a second joint 21. The spray pump head is adapted to be mounted on a container containing a liquid, and to press the pump head body 10, it pumps the liquid from within the container out of the outlet of the pump head body 10, into the inlet of the nozzle 20, and out through the outlet of the nozzle 20 in the form of a mist.

As shown in fig. 2, the outlet end of the first coupling portion 11 is provided with a tapered first introduction section 112, the first introduction section 112 is tapered to guide the first coupling portion 11 to be inserted into the nozzle 20 more smoothly, and the outer periphery of the first coupling portion 11 is provided with several turns of the retaining latch 111, preferably 3 to 8 turns, and more preferably 5 turns.

The inlet end of the second coupling portion 21 is provided with a tapered second lead-in section 212, functioning similarly to the first lead-in section 112, the second coupling portion 21 being provided with an elastic collar 211 attached to the inner periphery of the nozzle 20. The elastic collar 211 is made of rubber and can be elastically deformed when being pressed. When the pump head body 10 and nozzle 20 are assembled, the end of the pump head body 10 is simply inserted into the nozzle 20 along a straight line, and installation is quick and simple. When the two parts are assembled, the elastic ferrule 211 is elastically deformed to automatically fill the retaining latch 111 of the first coupling portion 11, and the elastic ferrule 211 also serves as an elastic member to ensure the sealing between the first coupling portion 11 and the second coupling portion 21 and effectively prevent the separation. The material of the first coupling portion 11 may be metal or plastic, and is preferably metal.

The first lead-in section 112 and the second lead-in section 212 make the assembly of the pump head body 10 and the nozzle 20 easier, and only the first lead-in section 112 or the second lead-in section 212 may be provided as required.

As shown in fig. 1, 3 and 4, the present novel embodiment 2 is substantially the same as embodiment 1 except that four open grooves 211 'are uniformly distributed along the radial direction at the end of the second joint portion 21'. The open slot 211' is provided to make the end of the second combining portion 21 have elasticity, and after being assembled with the first combining portion 11, the end can be tightly hooped on the periphery of the first combining portion 11 to prevent the two from loosening. The number of the open grooves 211 'may be set as required, and preferably, three open grooves 211' may be uniformly distributed in the radial direction.

The inner circumference of the section of the opening groove 211 ' of the second combining part 21 ' is provided with a backstop latch 212 ' which is matched with the backstop latch 111 of the first combining part 11. So, simple quick when the equipment spraying pump head, the back of assembling, the stopping latch of mutually arranging can further prevent to loosen and take off.

In addition, a sealing groove 213 ' and a sealing rubber ring 214 ' as an elastic member are further provided on the inner periphery of the second coupling portion 21 ', so that the sealing property of the spray pump head can be further ensured.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
