Title: Sprayer with writing function

Description:
BACKGROUND OF THE INVENTION  
       [0001] The present invention is related to a sprayer, and more particularly to a sprayer with both spraying function and writing function. In addition, it is easy to refill the sprayer with the liquid.  
       [0002] The current sprayer has small size and is easily portable. Such sprayer is often designed with accessory functions. The sprayer has a tubular main body and an atomizer directly plugged in one end of the main body. Several cells and a bulb are plugged in the other end of the main body. Such sprayer has simple structure and can be easily assembled. However, the outer diameter of such sprayer will be considerably large so that it is uneasy for a user to hold and write. Moreover, after the liquid contained in the sprayer is exhausted, such sprayer lacks suitable design for a user to easily refill the sprayer with the liquid.  
       SUMMARY OF THE INVENTION  
       [0003] It is therefore a primary object of the present invention to provide a sprayer with writing function, which has simple structure and can be manufactured at low cost.  
       [0004] It is a further object of the present invention to provide the above sprayer with writing function. The sprayer can be easily assembled and disassembled so that a user can conveniently refill the sprayer with the liquid.  
       [0005] According to the above objects, the sprayer of the present invention includes: a main body which is a cylindrical body having two open ends, a diaphragm being integrally formed in the main body to divide the interior thereof into a first chamber and a second chamber; an atomizer disposed on a predetermined section of the open end of the first chamber, the atomizer including a nozzle seat and a nozzle unit disposed on the nozzle seat and extending into the first chamber; and a writing device disposed at a predetermined section of the open end of the second chamber and having a hollow barrel body. A pen core is disposed in the barrel body. The sprayer provides both spraying function and writing function. The sprayer has simple structure and is manufactured at low cost. In addition, it is easy to refill the sprayer with the liquid.  
       [0006] The present invention can be best understood through the following description and accompanying drawings wherein:

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
     [0013] Please refer to FIGS.  1  to  5 . The sprayer  1  of the present invention includes a main body  10 , an atomizer  20  disposed at one end of the main body  10  and a writing device  30  disposed at the other end of the main body  10 .  
     [0014] The main body  10  is a cylindrical body having two openings at two ends. Each end of the main body  10  is formed with a connecting section. A diaphragm  11  is integrally formed in the main body  10  to divide the interior of the main body  10  into a first chamber  12  and a second chamber  13 . The capacity of the first chamber  12  is larger than that of the second chamber  13 . The outer circumference of the open end of the first chamber  12  is formed with outer thread. The outer circumference of the open end of the second chamber  13  is also formed with outer thread as a first screwed section  131 . The outer diameter of the main body  10  is larger than the outer diameter of the open end of the second chamber  13 , whereby a step section is formed between the main body  10  and the second chamber  13 .  
     [0015] The atomizer  20  is disposed at the open end of the first chamber  12 , including a nozzle seat  21 . The nozzle seat  21  has an upper cylindrical seat  211  disposed on the open end with its opening facing upward (in accordance with the direction of the FIG. 2). The outer circumference of the upper cylindrical seat  211  is formed with a first engaging section  213 . A lower cylindrical seat  212  is disposed at the lower end of the upper cylindrical seat  211  with its opening facing downward. The inner circumference of the lower cylindrical seat  212  is formed with inner thread, whereby the atomizer  20  is screwed with the open end of the first chamber  12 . A guide section  214  is formed in the upper cylindrical seat  211  as a socket with its opening facing upward. A nozzle unit  22  is disposed on the nozzle seat  21  and composed of a movable valve  221 , a hollow movable stem  222 , a cock  223 , a locating member  224 , a spring  225 , a ball member  226  and a conduit  227 . Through the hollow movable stem  222 , locating member  224  and the conduit  227 , the movable valve  221  communicates with the first chamber  12 . The movable valve  221  is up and down movably disposed in the guide section  214  of the nozzle seat  21 . A cap  23  is fitted around the upper cylindrical seat  211 . The inner circumference of the open end of the cap  23  is formed with a second engaging section  231  for engaging with the first engaging section  213 . According to the above arrangement, a liquid contained in the first chamber  12  can be atomized and sprayed out as shown in FIG. 3.  
     [0016] The writing device  30  is disposed at the open end of the second chamber  13  and has a hollow barrel body  31 . Two ends of the barrel body  31  are respectively formed with a first opening  32  and a second opening  33 . The inner circumference of the first opening  32  is formed with inner thread as a second screwed section  321  for screwing with the first screwed section  131 . A pen core  34  is disposed in the barrel body  31 . A writing end of the pen core  34  extends through the second opening  33  and protrudes therefrom. The other end of the pen core  34  abuts against the diaphragm  11 . A pen socket  35  is fitted around the barrel body  31 . The inner circumference of the open end of the pen socket  35  is formed with a first insertion section  351 . The outer circumference of the barrel body  31  is formed with a second insertion section  312  adapted to the first insertion section  351 . Accordingly, the writing device provides a writing function as shown in FIG. 4.  
     [0017] Referring to FIG. 5, when filling the liquid into the present invention, the atomizer  20  is unscrewed from the main body  10  for filling the liquid thereinto.  
     [0018]FIG. 6 shows another embodiment of the present invention, in which the outer diameter of the open end of the second chamber  13  is equal to that of the main body  10 . The inner circumference of the open end of the second chamber  13  is formed with inner thread as a first screwed section  131 . The outer circumference of the first opening  32  is formed outer thread as a second screwed section  321  adapted to the first screwed section  131 .  
     [0019] According to the above arrangement, the present invention has the following advantages:  
     [0020] 1. The diaphragm  11  is integrally formed in the main body  10  to divide the interior of the main body  10  into a first chamber  12  and a second chamber  13 . The atomizer  20  and the writing device  30  are respectively disposed at two ends of the main body  10 , whereby the present invention provides both spraying function and writing function.  
     [0021] 2. The present invention has simple structure and is manufactured at low cost. In addition, the present invention can be easily assembled or disassembled. Also, it is easy to refill the sprayer with the liquid and replace the pen core.  
     [0022] The above embodiments are only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiments can be made without departing from the spirit of the present invention.
