Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a teat cleaning and disinfecting device for animals, especially dairy cows.

[Conventional technology]

In general, the teats of dairy cows are cleaned and disinfected after milking in order to prevent mastitis caused by bacteria that enter the teat orifice. Such cleaning and disinfection is usually performed by dipping the nipple in a cleaning disinfectant, spraying the cleaning disinfectant onto the nipple, or wiping the nipple with a cloth soaked in the cleaning disinfectant. . Of these methods, the first method, ie, the dipping method, is generally widely adopted because it performs relatively sufficient cleaning and disinfection and is relatively simple to operate.

Next, this dipping method will be briefly explained below with reference to FIGS. 3 and 4. The washer-disinfector used for dipping is comprised of a cylindrical chemical tank 12 and a washer-disinfector container 14, both of which are generally connected to a tube 16 that opens at the top of the washer-disinfector container 14, as shown in FIG. (hereinafter referred to as the first format), or
As shown in FIG. 4, communication is provided through a tube 18 that opens at the bottom of the cleaning/disinfecting container 14 (hereinafter referred to as the second type). In the first type, by compressing the chemical liquid tank 12 as shown by the two-dot chain line, the chemical liquid in the chemical liquid tank 12 passes through the tube 16 into the cleaning disinfection container 14.
The nipple 20 is immersed in this chemical solution to perform cleaning and disinfection. In addition, in the second type, by compressing the chemical liquid tank 12, then releasing it, and repeating this operation, the chemical liquid in the chemical liquid tank 12 is pushed up against the cleaning disinfection container 14, and then lowered, and this process is repeated. Then, the nipple 20 is cleaned and disinfected by this rising and falling chemical solution.

[The problem that the idea attempts to solve]

However, as described below, the above-mentioned conventional dip-type washer-disinfector did not have sufficient cleaning and sterilizing properties, and its operability could not be said to be easy.

That is, first of all, in terms of cleaning and disinfection properties, especially in the first type, since the nipple 20 is simply immersed in a chemical solution, aged epidermis or other foreign substances adhering to the nipple surface are washed and removed. Therefore, the chemical solution did not come into sufficient contact with the skin surfaces of the nipple 20 and the nipple opening 22, and therefore a sufficient cleaning and disinfecting effect was not achieved. Also, the second
Although it is said that cleaning and removal of deposits from the nipple surface is performed better in the type 1 type than in the first type because the chemical liquid is moved up and down, the flow of the chemical liquid is shown in Fig. 4. As shown, the liquid mainly flows along the circumferential surface of the container 14, and the operation of raising and lowering the liquid medicine, that is, the operation of compressing and releasing the liquid medicine tank 12, is inconvenient and lacks reliability, as will be described later. Therefore, cleaning and removal of the deposits is similarly not carried out sufficiently. Moreover, in this case, the flow of the medicinal solution mainly occurs along the periphery of the container 14 as described above, so
The removal of deposits on No. 2 was particularly insufficient, and therefore mastitis was not effectively prevented.

Next, in terms of operability, firstly, the washer-disinfector 10 is formed relatively vertically with the chemical solution tank 12 and the washer-disinfector 14, and these are connected in a straight line, so the overall length is It gets longer,
Inserting the nipple 20 into the container 14 requires a cramped posture. Secondly, the operation of compressing and releasing the chemical solution tank 12 is performed repeatedly, especially in the second method, but this operation must be performed in the aforementioned cramped posture, which is extremely inconvenient. Moreover, since the chemical liquid tank 12 is a synthetic resin molded product, it hardens especially in low temperature climates, requiring force for compression and poor release recovery properties, which further deteriorates operability and ensures the flow rate of the chemical liquid. It was something that could not be done.

As described above, the conventional deep-type washer-disinfector did not have sufficient cleaning and sterilizing properties, and its operability was also inconvenient and uncertain.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a dip-type washer-disinfector that has excellent cleaning and disinfection properties and can be operated easily and reliably.

[Means to solve the problem]

In order to achieve the above object, the animal teat cleaning and disinfecting device according to the present invention includes a bellows-shaped elastic drug solution tank having an opening at the top and an axially expandable elastic body, and a bowl-shaped cleaning and disinfecting container having an opening at the bottom. , a connecting pipe connecting the top opening and the bottom opening, and the angle between the axis of the bellows-shaped elastic drug solution tank and the axis of the bowl-shaped cleaning and disinfecting container is about 100° to 140°. It is characterized by being set within the range of .

In this case, the bottom opening of the bowl-shaped cleaning disinfection container is
It is preferable that the medicine liquid be ejected in the direction of the nipple, and that the bellows-shaped elastic medicine liquid tank be compressed between the middle finger, the index finger, and the thumb. Further, the bowl-shaped cleaning and disinfecting container and the connecting pipe can be integrally molded.

[Effect]

Both the chemical solution tank and the washer-disinfector container are shaped like bellows and bowls with relatively large diameters, and they are connected with their axes set in the range of about 100° to 140°, so the length of the washer-disinfector can be reduced. The length is shortened, and the nipple can be inserted into the washer-disinfector in a comfortable posture and easily.

Furthermore, when cleaning and disinfecting the nipple, the chemical solution tank is elastic and bellows-shaped and can be operated with a fingertip, so it can be easily compressed and at the same time completely released and restored even at low temperatures. Moreover, the chemical solution discharged by this method is ejected upward from the bottom opening of the washer-disinfector toward the teats and especially the teat openings, and after colliding with these, it is further flowed around these areas, so that surface deposits are removed. It is removed reliably and the skin surface is thoroughly cleaned and disinfected. Furthermore, since the rate of change in volume of the chemical liquid tank is greater than that of a conventional straight cylindrical tank, the chemical liquid tank can be made smaller, and the amount of chemical liquid can also be made relatively small. .

〔Example〕

Next, an embodiment of the animal teat cleaning and disinfecting device according to the present invention will be described in detail below with reference to the accompanying drawings.

In FIGS. 1 and 2, a washer-disinfector 30 according to the present invention includes a bellows elastic drug solution tank 32 having a top opening 32a, a bowl-shaped washer-disinfector 34 having a bottom opening 34a, and a connecting pipe 36. In this embodiment, the washer-disinfector 34 and the connecting pipe 36 are integrally molded, and the lower internal threaded joint of the connecting pipe 36 and the external threaded joint of the top opening 32a are connected to the chemical tank 32 for cleaning. It is in communication with a disinfection container 34. and,
The angle α between the axis of the chemical solution tank 32 and the axis of the cleaning/disinfecting container 34 is approximately 120°. Note that the angle α can be appropriately set within a range of approximately 100° to 140° depending on, for example, the physique of the operator. Furthermore, a hook 38, which is used when the washer-disinfector 30 is hung and stored, is detachably attached to the neck of the top opening 32a of the chemical solution tank 32.

The chemical liquid tank 32 is made of an elastic synthetic resin material, has a relatively large diameter and a short body, and is formed into a bellows body part 32b that is expandable and contractible in the axial direction, and is compressed between the middle finger, index finger, and thumb. It is configured so that The cleaning and disinfecting container 34 has a teat 2 inside it.
The opening 40 at the bottom opening 34a is shaped like a bowl into which the pipe 36 is inserted almost completely, and the opening 40 at the bottom opening 34a is formed into a curved surface on the left side of the connecting pipe 36 as shown in the figure.
The chemical liquid discharged by compression of the chemical liquid tank 32 is
It is configured to be ejected towards the nipple and in particular towards the nipple opening.

When cleaning and disinfecting the teats 20, the washer-disinfector 30 is held from the side of the dairy cow's body toward the lower part of the cow's body while holding its chemical solution tank 32 with the fingertips.
Insert the nipple 20 into the washer-disinfector 34. In this case, the washer-disinfector 30 is short in length, and the washer-disinfector 34 is connected to the chemical tank 32 at an angle of approximately 120°, so that the above-mentioned work can be easily performed, and the linear sterilizer 30 can be held in a comfortable position. Next, the held fingertip is moved to compress and release the chemical liquid tank 32, and this operation is repeated, but in this case, the chemical liquid tank 32 is compressed and released.
Since it is held in a comfortable position, the above-mentioned operation can be carried out easily, and since the chemical solution tank 32 is formed in an elastic bellows body 32b, it can be completely compressed and at the same time completely released even at low temperatures. The drug is restored and a desired amount of the drug is discharged or refluxed from the opening 40. Moreover, the medicinal liquid discharged from the opening 40 is ejected toward the nipple opening 22 of the nipple 20,
After colliding with the nipple opening 22 and the surrounding area of the nipple 20, it further flows around these areas. Therefore, surface deposits are removed and the skin surface is thoroughly and reliably cleaned and disinfected.

Although the present invention has been described above with reference to preferred embodiments, the present invention can be modified in many ways without departing from its spirit. For example, the cleaning/disinfecting container and the connecting pipe can be formed separately.

[Effect of idea]

As explained above, in the animal teat washer-disinfector according to the present invention, the chemical solution tank is configured as a bellows-shaped elastic body that is axially expandable, and the chemical solution tank is arranged in a bowl-shaped washer-disinfector. They are connected so that the angle formed by the axes is within the range of about 100° to 140°, and the chemical solution discharged from the bottom opening of the washer-disinfector is sprayed toward the teat and especially the teat opening. Therefore, the operability and cleaning/disinfecting performance of the washer/disinfector are greatly improved.

That is, since the washer-disinfector is small and has a box-shaped configuration, the teat can be easily inserted into the washer-disinfector, and the washer-disinfector can be held and operated in a comfortable posture. Further, since a predetermined amount of the chemical solution is injected and flowed in a colliding manner toward the nipple, particularly toward the nipple orifice, surface deposits are reliably removed and the skin surface is thoroughly cleaned and disinfected.
