Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a water purifier in which a raw water connection hose can be easily connected to a raw water injection end of a filter cartridge.
[0002]
[Prior art]
Many water purifiers have been proposed and used as the quality of domestic water including tap water deteriorates. Many small products that are directly attached to household water supply are also commercially available. Such ones are relatively easy to install, but have limited processing power. Many proposals have also been made for stationary types that can be used in medium-sized or commercial kitchens. In such a water purifier, since the raw water is usually introduced into the cartridge by the pressure of the raw water (for example, the pressure of tap water), the water purifier is often fixed using a relatively strong fastening fitting so that the hose does not come off.
[0003]
[Problems to be solved by the invention]
As mentioned above, the connection between the raw water source and the water purifier is not easy, and the housewives cannot do it easily. At first, the water purifier provider had to go to the sales outlet and install it. Moreover, once installed, it is not easy to remove and change the installation position.
The objective of this invention is providing the water purifier provided with the raw | natural water hose plug connection means which enabled easy attachment or detachment connection of the raw | natural water connection hose to the raw | natural water injection | pouring end of a filter cartridge.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, a water purifier comprising a raw water hose plug connecting means according to the present invention is basically a water purifier that introduces raw water into the water purifier at the raw water pressure and purifies it with a filter of the water purifier.

A fixed sleeve provided in the water purifier,
A hose plug receptacle provided coaxially in the fixed sleeve;
Click means that appears and disappears from the receptacle and engages and disengages from the click groove;
With cam means,
The hose lock knob is provided between the fixed sleeve and the hose plug receiving cylinder so as to be rotatable, and restricts the appearance of the click means.
An O-ring is disposed at the tip of the raw water hose plug, and is configured to be watertight with the hose plug receptacle tube downstream of the click groove.
One or more steel balls can be used as the click means.
The hose lock knob can be provided with an index indicating a position where the raw water hose can be attached and detached.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of a water purifier according to the present invention will be described with reference to the drawings. FIG. 1 is a sectional view showing an embodiment of a water purifier according to the present invention. FIG. 2 is an expanded view of an embodiment of the water purifier according to the present invention. The spout head 1 is integrally provided with a spout 5 from which purified water is supplied. The tightening handle 2 has a female screw coupled to the male screw at the tip of the cartridge 9 and fastens and fixes the body 8. The spout water intake pipe 4 is water-tightly connected to the top hole of the cartridge 9 by an O-ring 6, and water that has passed through the cartridge 9 is supplied from the spout head 1 to the spout 5 via the spout water intake pipe 4. The tightening handle 2 is sandwiched between the stopper ring 3 and the spout head 1, and the spout head 1, the spout 5, and the spout water intake pipe 4 rotate integrally with the cartridge 9 to define the water supply direction.
[0006]
The cartridge 9 is composed of the above-described upper portion (lid portion) 9a and a barrel portion 9b coupled to the upper portion, and a stopper ring 19 is used at the center of the bottom of the barrel portion to provide one or two filters 18. Is detachably provided. As is well known, various filter materials and raw water activation materials are inserted into the cartridge 9. The filling of the filter material into the cartridge 9 is performed with the upper side (lid) 9a removed.
[0007]
Although this embodiment shows an example in which two filters 18 are used, the filter 18 is a porous ceramic plate, and the number or use time thereof is determined based on the quality of raw water. It is extremely good quality water, has no pollutant, and is sufficient if it is sufficient to activate raw water, or in extreme cases, or it can be used for a long time without replacing one sheet.
An opening cylinder 9c is provided at the bottom of the body portion 9b of the cartridge 9, and a filter 18 is inserted into the cylinder 9c in a replaceable manner. On the outer surface of the opening cylinder 9c, a male screw is provided for screw coupling to a base 11 described later.
[0008]
The base 11 has 11a coupled to 9c of the cartridge 9 described above and 11b coupled to the lower end of the body 8 on the upper outer periphery.
Toward the lower side in the middle, cylindrical 11c having an opening facing the filter cartridges 9 are provided, the main pipe 12 is coupled to the cylinder 11c. A hook-like portion connected to the side passage 12 a of the main pipe 12 is connected to the end surface (see FIGS. 1 and 3) on the center side of the fixing sleeve 15 and fixedly supported on the side surface of the base 11 via the fixing sleeve 15. ing.
Two holes for receiving a pair of click balls 13 are provided through the tube wall of the distal end portion (the portion protruding into the fixed sleeve 15 and constituting the receiving cylinder) continuous with the side path 12a (see FIG. 2) .
The side surface inner surface side of this hole is smaller than the diameter of the click ball (steel ball) 13 and a part of the click ball 13 can be faced in the side channel 12a, but the click ball 13 does not fall into the side channel 12a. It is like that. A hose lock knob 14 is rotatably inserted between the fixed sleeve 15 and the portion that forms the receiving tube that is continuous with the side passage 12a of the main pipe 12. Surface corresponding to the click ball 13 in the hose lock knob 14 is turned in a circumferential cam shape. By rotating the hose lock knob 14, the click ball 13 can be positioned at either the position where the click ball 13 is pushed out into the groove of the hose plug 17 or the position where the click ball 13 is retracted.
[0009]
In this embodiment, as shown in FIG. 2, the tip side of the hose lock knob 14 and the portion appearing outside the base 11 are indexed, and this portion is attached to a specific angular position of the fixing sleeve 15. The hose plug 17 can be inserted or withdrawn when it is adjusted to. The hose plug 17 is inserted at this position and the hose lock knob 14 is rotated to lock the assembly of the hose plug 17 and the hose to the base 11. The hose 30 is connected to a raw water source such as a tap.
[0010]
FIG. 3 is an enlarged view for explaining in more detail the coupling state between the hose plug 17 and the side passage 12a of the main pipe 12. As shown in FIG. A hose 30 is coupled to the bamboo shoot portion of the hose plug 17, and raw water is supplied through the hose 30. In the vicinity of the tip of the hose plug 17, an O-ring 16 is provided to keep watertight between the side passage 12 a of the main pipe 12 and the tip of the hose plug 17. The hose lock knob 14 is moved to a position where the click ball 13 can be retracted from the groove 17a of the hose plug 17 (position shown in the figure), the hose plug is inserted, the hose lock knob 14 is rotated, and the click ball 13 When the hose plug 17 is returned to the position where it cannot be retracted from the groove 17a of the hose plug 17, the hose plug 17 is fixed. When removing the hose plug 17, the click ball 13 may be pulled out from the groove 17 a of the hose plug 17 (position shown in the drawing) so that the hose 30 is pulled out.
