Abstract:
A wristband type electric nose cleaner provides an electric spray-suction pump assembly, which applies the Bernoulli&#39;s theorem to provide a function of atomization for the cleaning solution. A spray device and a suction device are involved in the nose cleaner such that the foreign matters such as mucus can be sucked out of the nose and the cleaning solution such as normal saline can be injected into the deep inside nasal cavity in a state of being atomized to enhance the nose clean job. Furthermore, a wristband is attached to the nose cleaner for fixing the nose cleaner firmly to the wrist of a user to prevent the nose cleaner from damage resulting from falling from the hand.

Description:
BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    The present invention relates to a wristband type nose cleaner, and, particularly, to a portable house electric nose cleaner, which performs washing the nose with mist spray or removing foreign matters in the nose with sucking air.  
           [0003]    2. Description of Related Art  
           [0004]    The nose cleaner available in the market such as a push type nose washer, a push type nose suction device or a mouth aspirating type nose suction device has a single function only and has to be operated manually. The conventional nose cleaners usually provide an extensible container for being pressed and released repeatedly with the hand of a user or being sucked with the mouth of the user such that the air in the container can be pressed to constitute fast moving air for cleaning the nose by way of being sprayed or sucked. Although the conventional nose cleaners are not bad from the standpoints of the principle applied and the way of design, problems such as unsuitable for use and improper regulated air pressure are still there. A further detail with regard to the disadvantages is stated hereinafter.  
           [0005]    During the manual push type nose washer or the manual push type suction device being operated manually by the user in a way of pressing and releasing the extensible container repeatedly, a defect worth us to care is it is hard to control the pressing force appropriately. Especially for the infant, the mucous membrane in the infant&#39;s nose is very weak and it is very easy to become hurt if the cleaning solution (such as normal saline) is sprayed with an excessively large force or the foreign matter (such as nasal mucus) is sucked out of the nose with an excessively large force. If the force is excessively small, the cleaning solution is unable to eject smoothly or the foreign matter is not possible to be sucked out completely. By the same token, the conventional mouth aspirating type suction device also has the problem of pressing force with a possibility of indirect infection of cold virus (such as droplet infection through mouth aspirating).  
           [0006]    During the push type nose washer or the push type suction device being used, the repeated movements of pressing and releasing cause the extensible container being in a state of shaking and it is hard to locate the contact port thereof at the nose. In this way, it is not convenient to be operated and it is very likely to hurt the mucous membrane in the nose.  
           [0007]    The cleaning solution ejected from the push type nose washer is a liquid state to forcedly wash the nasal cavity so that it is easy to irritate the nose or to cause cough if the cleaning solution stimulates the mucous membrane of the nasal cavity too much. Further, the cleaning solution ejected by the push type nose washer is not possible to become atomized so that it is hard to clean the deeper inside of the nasal cavity and a great deal of cleaning solution has to be used.  
           [0008]    It is not easy to carry or store up the push type suction device and the mouth aspiration suction device and the container thereof for receiving the foreign matter such as nasal mucus sucked out of the nose is made of material not resisting the high temperature of boiling water during the process of boiling sterilization.  
           [0009]    Further, The preceding conventional nose cleaners provide undesirably effect of nose cleaning.  
           [0010]    The conventional nose cleaners available in the market are usually designed to have a hand grip respectively so that it is easy to fall down carelessly and become damaged.  
           [0011]    As the foregoing, it is known that there are disadvantages while the conventional nose cleaners are in use. Moreover, when the conventional nose cleaners are used for cleaning the infant&#39;s nose cavity, it has to be taken extreme care during performing the nose clean job.  
         SUMMARY OF THE INVENTION  
         [0012]    The crux of a wristband type electric nose cleaner according to the present invention resides in that the wristband type electric nose cleaner includes a casing, a pump being fixed in the casing, a motor with an eccentric shaft being joined to rear side of the pump, a suction device detachably engaged to an end of the pump and a sprayer can detachably engaged to the end of the pump. When the motor is started to run, foreign matters can be sucked out of the nose in case of the suction device being mounted to the pump and clean solution can be sprayed deeply into the nose in case of the sprayer being mounted to pump instead of the suction head.  
           [0013]    Accordingly, a primary object of the present invention is to enhance the nose clean job so that the nose cavity can be cleaned more effectively and conveniently with reduced cleaning solution needed.  
           [0014]    Another object of the present invention is to promote the effectiveness of the cleaning solution because of the cleaning solution being atomized such that it is helpful for the atomized cleaning solution to reach deeper inside the nasal cavity and to avoid occurring nose irritating or throat coughing.  
           [0015]    A further object of the present invention is to avoid mucous membrane of the nasal cavity being stimulated or hurt during the nose clean job.  
           [0016]    A further object of the present invention to provide an electric nose cleaner, which has a compact size for being portable conveniently, with a wristband can be attached to a wrist firmly to avoid damage resulting from falling down from the hand.  
           [0017]    A further object of the present invention to provide a wristband type electric nose cleaner, which can spray atomized cleaning solution into the nose and can suck the foreign matters out of the nose instead with facility regardless the power source is alternate current or direct current.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0028]    Referring to FIGS. 1, 2 and  3 , a wristband type electric nose cleaner of the present invention has a pump  10  and a suction device  30 , wherein, the pump  10  is fixedly attached to the inner side of a casing  28 . The pump  10  has a pump body  11  with a spray outlet tube  12  and a suction inlet tube  13  extending outward the casing  28 . A spray-suction valve plate  14  is arranged in the pump body  11  and a valve cover  17  fits with the pump body  11  at a lateral side of the pump body  11  next to the valve plate  14 . The valve plate  14  has a spray valve gate  15  and a suction valve gate  16  and the valve cover  17  has an air spray chamber  19  and an air hole  18 . The air hole  18  is arranged to communicate with the air spray chamber  19 , and the air hole  18  can communicate with or disconnect from the suction inlet tube  13  by way of controlling the suction valve gate  16 . Similarly, the air spray chamber  19  can communicate with or disconnect from the spray outlet tube  12  by way of controlling the spray valve gate  15 . A sucking disk  20  is disposed at a lateral side of the valve cover  17  opposite to the valve plate  14  and is fixedly attached to the valve cover  17  with a pump cap  23 . The sucking disk  20  has an air chamber  21  corresponding to the air hole  18  and an axial projection stem with a shaft hole  22  to pass through an axial bore  24  in the pump cap  23 . The shaft hole  22  is passed through with an eccentric shaft  26  on a motor  25  such that the axial projection stem of the sucking disk  20  can reciprocate to result in the air chamber  21  being compressed and released repeatedly during the motor  25  is in a state of running. In this way, the suction gate  16  of the valve plate  14  can open and shut the suction inlet tube  13  and the suction inlet tube  13  can detach from the suction gate  16  to admit the air current outside the suction inlet tube  13  while the air chamber  21  is released and the suction inlet tube  13  is shut with the suction gate  16  and the air in the air chamber  21  passes through the spray chamber  19  from the air hole  18  to open the spray valve gate  15  and discharges via the spray outlet tube  12 . The suction device  30  has a suction cover  31  with a sucking hole  32  is inserted into a joint fixing base  29  on the casing  28  as shown in FIG. 9 so that the sucking hole  32  can align with the suction inlet tube  13 . The suction cover  31  at the lateral side thereof has an engaging recess part  34  to join the spray outlet tube  12 . The engaging recess part  34  has a discharge recess  39  being disposed to fit and communicate with the spray outlet tube  12  so that the air can be discharged via the discharge recess  39  and the spray outlet tube  12 . A suction tube  33  is provided on the spray cover  30  next to a lower end of the suction hole  32  to connect with a suction tube  37  via a connecting tube  36 . The suction tube  37  with a sucking passage  38  sucks the foreign matter in the nasal cavity into the nose cleaner. Further, a suction container  35  fits with the suction cover  31  to receive the foreign matter.  
         [0029]    As the foregoing, once the motor  25  is started to run, the eccentric shaft  26  actuates the air chamber  21  of the sucking disk  20  in the pump  10  to perform the repeated movements of compressing and releasing such that the spray valve gate  15  and the suction valve gate  16  can react a reverse movement respectively with respect to the spray chamber  19  and the suction inlet tube  13  to result in one of the gates  15 ,  16  being opened and the other one of gates  15 ,  16  being shut alternately. The suction inlet tube  13  attracts the air in the suction container  35  to enter the air hole  18  via the sucking hole  32  at the moment of the air chamber  21  stretches inversely toward the air hole  18 . The suction valve gate  16  can be pushed toward the suction inlet tube  13  to close the suction inlet tube  13  at the moment of the air chamber  21  being pushed by the eccentric shaft  26  and moving toward the air hole  18 . In the meantime, the air from the air hole  18  pushes the spray gate  15  away via the spray chamber  19  and the air can be discharged from the spray outlet tube  12  via the discharge recess  39  such that the suction container  35  becomes in a state of vacuum and the foreign matter in the nose can be sucked into the suction container  35 . Therefore, the spray valve gate  15  and the suction valve gate  16  opening and shutting alternately allows the suction container  35  being in a state of semi-vacuum or full of the air so that the foreign matter can stay in the suction container  35  without entering the sucking hole  32 .  
         [0030]    Referring to FIGS. 4, 5 and  6 , the sprayer  40  has a spray cover  40  with an atomization chamber  43  and a spray nozzle  44  is arranged in the atomization chamber  43  such that an air passage  45  in the nozzle  44  communicates with an air adapter  42  extending from the atomization chamber  43 . The air passage  45  at another end thereof extends an atomization hole  46  to communicate with a liquid groove  47  at the lateral side thereof and at an end of the atomization hole  46  is provided with a spray hole  48 . The liquid groove  47  further communicates with a liquid tube  49  attached to the atomization chamber  37  on the sprayer cap  41 . The air adapter  42  fits with an end of a connecting tube  50  and a connector  51  at an end thereof fits with another end of the connecting tube  50 . Once another end of the connector  51  is connected to the spray outlet tube  12  of the pump  10 , the air is sucked into the pump  10  via the suction inlet tube  13  as soon as the motor  25  is started to run. Then, the air moves along an air passage  52  in the connector  51  and the connecting tube  50  to enter the air passage  45  via the adapter  42  so that the air can be ejected via the atomization hole  46  and the spray hole  48 . When the air passes through the atomization hole  46  and the liquid groove  47  becomes in a state of vacuum, the cleaning solution  54  in the spray container  53  is sucked to the atomization hole  46  via the liquid tube  49  to mix with the air and the mixture can be atomized before being injected into the nose from the spray hole  48  for cleaning the nasal cavity.  
         [0031]    Referring to FIGS. 7 and 8, another embodiment of the present invention is illustrated. It can be seen that a connecting seat  60 , which is fixedly attached to the pump  10 , is provided with a plurality of air grooves  63  at the inner wall thereof. An airflow tube  61  with air grooves  62  arranged at the tube wall thereof is provided in the connecting seat  60  and the airflow tube  61  is fixedly attached to the suction inlet tube  13 . Hence, the air can enter the airflow tube  61  and the suction inlet tube  13  after coming into the connecting seat  60  through the air grooves  63  and moves toward the sprayer  40  via the spray outlet tube  12 . Further, an air guide tube  64  extends from the connecting seat  60 . The connecting seat  60  can be used instead of the preceding connector  51  such that it can prevent the user from connecting the connector  51  to the suction inlet tube  13  carelessly.  
         [0032]    Referring to FIG. 9, it can be seen from the appearance of the electric nose cleaner of the present invention that the spray outlet tube  12  and the suction inlet tube  13  jut out from the joint fixing base  29  of the casing  28  thereof in a way of being disposed at asymmetrical positions to each other with respect to the center of the joint fixing base  29 . In this way, the mistake resulting from the spray outlet tube  12  and the suction inlet tube  13  are misconnected during the suction device  30  and the connecting seat  60  being inserted into the joint fixing base  29 . Further, the casing  28  at the rear side thereof is attached with a wristband  70  such that the electric nose cleaner of the present invention can be located at a wrist of the user and the nose cleaning job for the nose patient can be performed with facility. Moreover, the power source and a control circuit for the power switch can be arranged in the nose cleaner of the present invention to ease the operation of the nose cleaning.  
         [0033]    While the invention has been described with reference to the preferred embodiments thereof, it is to be understood that modifications or variations may be easily made without departing from the spirit of the invention, which is defined by the appended claims.
