Pitcher-type water purifier

Technical field

The present invention relates to pitcher-type water purifier.

The present invention is based on and advocated right of priority patent application 2006-311725 number of Japanese publication and on March 26th, 2007 patent application 2007-078795 number of Japanese publication on November 17th, 2006, quoted its content at this.

Background technology

In the past, known have a pitcher-type water purifier with the water purification cartridge of purifying waste water.Therefore this pitcher-type water purifier can be kept purification function by replacing to new water purification cartridge because its water purification cartridge loads and unloads setting freely under the situation that purification function reduces.More particularly, pitcher-type water purifier contains the container that former water is used in its inside with container body of handle, and the bottom of the container of using at this former water is equipped with water purification cartridge.And, by this water purification cartridge, fall in the container body and be stored while the former water that is housed in internal tank is cleaned with its deadweight.Again, be used for water purification is injected the water filling port of cup etc. and the lid that the peristome of the container body except that water filling port is opened and closed being provided with on the container body, the user hand handle tilt container body, then only water purification by water filling port injection glass.

Yet, in recent years, also wish further to improve the commodity of above-mentioned pitcher-type water purifier, such product is for example arranged: replace water purification cartridge in order not waste above-mentioned water purification cartridge with the rational replacement cycle, the number of times that former water promptly is provided of opening of lid is counted and shown (for example with reference to patent documentation 1).

Patent documentation 1: Japanese Unexamined Patent Application Publication is opened the 10-50937 communique

Invent problem to be solved

But, in the above-mentioned pitcher-type water purifier in the past, because lid is Embedded and is loaded and unloaded freely and to be provided with, therefore exists such problem: for example container falls down or for some reason container body is applied when impacting, and also can not break away from container body although be not when this is stamped when supplying water.

Therefore, replace water purification cartridge according to the count results of the switching number of times that covers, then can be more Zao than the moment that should replace, the replacement frequency gets higher of water purification cartridge.On the other hand, so that lid is difficult to break away under the situation of container body, though the frequency that lid breaks away from reduces, user's burden increases when supplying water because lid is difficult to break away from etc. in the chimeric of further firm lid and container.

Again, in the above-mentioned pitcher-type water purifier in the past, lid with to lid to open the counter that number of times counts integrally formed, constituting counter can't be from the structure of lid disengaging, therefore also exist such problem: be difficult to discarded respectively, can be used as so-called resource rubbish round-robin part and also must be used as non-combustible waste and handle, the burden of environment is increased.

Summary of the invention

At this, the invention provides a kind of can prevent to cover because of impact break away from and the pitcher-type water purifier of the operation of supplying water easily when supplying water.

Again, the present invention also provides a kind of pitcher-type water purifier that can alleviate the burden of environment.

In order to address the above problem, the present invention has following formation.That is, first example of the present invention is characterized in that, comprising: container body (for example container body 2 in first example); Loading and unloading are installed in the upper container (for example former water pot 4 in first example) on the top of this container body freely; The interconnecting part (for example hole 13 in first example) that is communicated with the bottom of described container body in the part of described upper container; Loading and unloading are installed on the water-purifying filter (for example water purification cartridge 14 in first example) of this interconnecting part freely; At the cap (for example lid 3 in first example) that the peristome (for example peristome 17 in first example) of described container body opens and closes sliding freely to this peristome, this cap can located along the position more than two places of slip direction.

Second example of the present invention is characterised in that, in first example of the present invention, described cap at least can be in the location, position of only opening pure water inlet (for example water filling port 10 in first example), and described pure water inlet is formed by the water filling port of the peristome of described container body and the space that exterior region surrounded of upper container.

The 3rd example of the present invention is characterised in that in of the present invention first or second example, to have the counting mechanism that the water supply number of times is counted.

Embodiment

Below, according to Fig. 1～Fig. 6 first example of the present invention is described.

In Fig. 1, the pitcher-type water purifier of symbol 1 expression first example of the present invention.This pitcher-type water purifier 1 comprises that mainly container body 2, lid 3, so-called former water pot are upper container 4.

Container body 2 forms the barrel shape that the end is arranged that is made of diapire 5, antetheca 6, left and right sides sidewall 7,7 and rear wall 8, and handle 9 is integrally formed with rear wall 8, and is formed with water filling port 10 on the antetheca 6 of the opposition side of handle 9.And antetheca 6, left and right sides sidewall 7,7 and rear wall 8 bight between is separately formed by curved surface, and in the bottom surface of the diapire 5 of container body 2 the not shown ring-shaped rubber as anti-skidding thing is installed.

Water filling port 10 is chevron and forms by the substantial middle on the left and right directions of the upper limb 11 of antetheca 6 part is forwards outstanding, on the antetheca 6 that is formed with this water filling port 10, along with downwards from upper limb 11, the overhang of this water filling port 10 reduces gradually, thereby sees substantial middle portion convergence at the above-below direction of the container body 2 of essentially rectangular shape from cross section.By such formation water filling port 10, between antetheca 6 and former water pot 4 (details aftermentioned), form the path of the bottom of leading to container body 2, it is oblique to water filling port 10 inclinations with pitcher-type water purifier 1 to control handle 9, and the water purification that then is stored in container body 2 injects outside container etc. by path.

As shown in Figure 2, the upper limb of the left and right sides sidewall 7,7 of container body 2 is parallel to each other, and the outside at the upper limb of this left and right sides sidewall 7,7 is formed with track R, R respectively along its upper limb.This track R, R are side-prominent more outwardly to the bottom more from top, and its cross section is roughly hook-shaped (with reference to Fig. 3).Again, on the substantial middle part of the fore-and-aft direction of the upper limb of left and right sides sidewall, be provided with the otch 7a of mortar shape, by forming this otch 7a, when the former water pot 4 that will load and unload the top that is housed in container body 2 is freely pulled down, can easily catch its upper limb, so can easily carry out the dismounting of former water pot 4.

Former water pot 4 forms its bight by curved surface forms, cross-sectional shape is essentially rectangular the bottom tube-like that has.On its diapire 12, be formed with the hole (interconnecting part) 13 that is communicated with the bottom of container body 2.And the water purification cartridge of tubular (water-purifying filter) 14 can be arranged on this hole 13 from the inboard of former water pot 4 with loading and unloading, and this water purification cartridge 14 is outstanding downwards from diapire 12 under the state of installing.At this, water purification cartridge 14 has and the former water pot 4 interior not shown former water inlets that are communicated with at an upper portion thereof, and its underpart have with container body in the not shown pure water inlet that is communicated with, in the tubular path between former water inlet and pure water inlet, be provided with strainers such as sorbent materials such as gac or hollow fiber membrane, the former water conservancy that flows into from above-mentioned former water inlet flows through path in the water purification cartridge 14 with its deadweight, and discharges downwards from pure water inlet as water purification.

The periphery of the peristome 15 of former water pot 4 is provided with the flange part 16 that is bent to form approximate right angle laterally, when the peristome 17 of container body 2 inserts former water pot 4, this flange part 16 is stuck in the peripheral part of the peristome 17 of container body 2, and former water pot 4 is fixed on the top of container body 2.

Again, the front side at the periphery of the peristome 15 of former water pot 4 is formed with the next door 18 that links to each other and forwards extend with aforesaid flange part 16.Liner (the パ of this next door 18 and lid 3 described later _StarThe キ Application) 19 (with reference to Fig. 3) separate the inside of former water pot 4 and the water filling port 10 of container body 2 together, and its upper surface becomes the even surface of being pushed by liner 19.

And, as shown in Figure 4, under former water pot 4 is housed in state in the container body 2, for the leading edge 20 in

next door

18,6 upper limb 11 is formed up to after the position that enters slightly to the inside from its left and right sides along antetheca, is formed with to leave the

recess

21,21 that upper limb 11 rearward caves in into the mortar shape.And, by the substantial middle position of the left and right directions of the leading edge 20 of these

recess

21,21 clampings, be formed with forwards outstanding protuberance 22 with the roughly the same shape of profile of upper limb 11.At this, the upper limb 11 and protuberance 22 arranged spaced of antetheca 6, this space constitutes the peristome 23 of water filling port 10.

On the other hand, on container body 2, loading and unloading are provided with the lid 3 that its peristome 17 is opened and closed freely, and this lid 3 can slide on fore-and-aft direction by above-mentioned track R, R.

Lid 3 comprises: main board portion 30; From left border, margo dexter and the posterior lateral margin of this main board portion 30 outstanding formation and surround the left and right sides sidewall 31,31 (diagram only illustrates left side wall 31 among the figure for convenience) and the rear wall (not shown) of the upper limb of the left and right sides sidewall 7,7 of container body 2 and rear wall (with reference to Fig. 1) from the outside downwards; Link to each other with the front portion of main board portion 30 and forwards extend to form, with the profile of the water filling port 10 of above-mentioned container body 2 corresponding before board 33.

Middle body in main board portion 30 has the scarp 34 of direction back lower place inclination in the past, and more caving in than its periphery 35 in the rear portion on this scarp 34, forms recess 36.This recess 36 plays the effect of so-called handle, and to cover 3 be to slide in the rear to opening direction thereby the user can easily make finger hook at this recess 36.

As shown in Figure 3, main board portion 30 from the left and right sides sidewall 31,31 that left and right sides lateral margin extends downwards, be formed with from the outstanding to the inside raised line 37 of its lower edge.And this raised line 37, left and right sides sidewall 31,31 and main board portion 30 constitute cross-sectional shapes and are the roughly recess 38 of U font, this roughly the recess 38 of U font play the effect of groove.At this, recess 38 will be inserted behind above-mentioned track R and flange part 16 laminations, make and cover 3 and forwards move and when being installed on the container body 2, raised line 37 is stuck in the bottom of track R, limited and covered 3 to i.e. the moving upward of the direction that breaks away from container body 2 from the rear of container body 2 along track R.

At this, lid 3 is provided with liner 19, this liner 19 forms that the inboard slightly position of the raised line 39 (aftermentioned) of the periphery of board 33 is along the ring-type of this raised line 39 along the left and right sides lateral margin of main board portion 30 and posterior lateral margin and before being formed at, and this liner 19 is sandwiched between this main board portion 30 and the flange part 16.And, because this liner 19 sandwiched between this main board portion 30 and the flange part 16, historical facts or anecdotes showed cover 3 and former water pot between sealing.In addition, though the situation that liner was arranged in 19 minutes is illustrated, also can it is integrally formed with lid 3.

As shown in Figure 4, preceding board 33 mainly is that the peristome 23 to water filling port 10 opens and closes, and it links to each other with above-mentioned main board portion 30 and forwards extends, and it is that peristome 17 forward shapes are corresponding that the shape of its tip side forms with the shape of described water filling port 10.On the periphery of preceding board 33, be formed with outstanding raised line 39 downwards again.

Again, the rear wall (omitting diagram) that extends downwards from the posterior lateral margin of main board portion 30 cover 3 too under the situation of front slide will making, and with the outside surface butt of the rear wall 8 of the peristome 17 of container body 2, by this rear wall, covers 3 position, forefront and is positioned.

On the other hand, the front portion of peristome 17 peripheries of container body 2 is shaped to stepped, the vertical face of the step portion B of this stepped moulding (with reference to Fig. 2) and track R orthogonal collocation.That is to say that making and covering 3 is the place ahead when sliding to closing direction, the front end of the left and right sides sidewall 31,31 of this lid 3 and the vertical face butt of step portion B and can't continue forwards to slide, the same with the rear wall of above-mentioned lid 3, cover 3 position, forefront and be positioned.

Again, thus above-mentioned lid 3 constitutes by making its sliding action that it can also be positioned in the position beyond above-mentioned.More specifically, as shown in Figure 1, lid 3 at first is positioned by the detent position of complete closed at peristome 17, slide if rearward promptly open direction from this position, lid 3 perfusion water purifying location of water injection shown in Figure 5 promptly only the peristome 23 of the water filling port 10 overlapped position of leading edge of opening, cover the protuberance 22 in the leading edge of 3 preceding board 33 and next door 18 be positioned.

At this, the location of above-mentioned location of water injection is to instigate when covering 3 slips to obtain restraining sense (covering the feel that 3 clicks are rattled away and temporarily stopped) in above-mentioned location of water injection.As the mechanism that carries out this location usefulness, as long as can obtain the restraining sense, for example, can constitute: on lid 3, not shown projection or hole are set, on the other hand, on container body 2, be provided with and corresponding not shown hole of projection or hole or the projection of covering 3, make projection and the corresponding hole of this projection chimeric in above-mentioned location of water injection.In addition, at container body 2 or cover and be provided with protuberance on 3, this hole can be arranged on the roughly top of this protuberance.Again, can also haunt is provided with above-mentioned projection freely, utilizes elastic component towards the projected direction application of force.

By such location, make and cover 3 and slide and when carrying out opening action from closing condition, make 3 power of sliding of cover sharply increase and be positioned in location of water injection shown in Figure 5, cover 3 slips if do not make with bigger power, just can further not carry out opening action.And, cover 3 and slide and further to carry out opening action if make with bigger power, increased make 3 power of sliding of cover be reduced to increase before equal degree, slide to opening direction like this, as shown in Figure 4, lid 3 is just from container body 2 disengagings.In addition, the location of lid 3 is not limited to location of water injection and off-position two places, for example as shown in Figure 6, also can position covering 3 in the half-way of unloading lower cover 3 from container body 2.Like this under the situation that the half-way of unloading lower cover 3 positions, can prevent to cover 3 because some reason slide arbitrarily and come off from location of water injection.

Yet, do not cause waste though when filtered former water reaches specified amount, replace above-mentioned water purification cartridge 14, comparatively desirable, add up the former water yield, the parts formation complicates, and cost uprises.Therefore, replacement period of water purification cartridge 14 is generally according to judging duration of service of water purification cartridge or the number of times of supplying with former water.

And, in the pitcher-type water purifier 1 of first example of the present invention, be built-in with the counter 40 of reference standard of the switching number of times of this lid 3 being counted and shown replacement period of water purification cartridge 14 in 3 at lid.

As shown in Figure 1, wait the operating switch of operating 42, these display parts 41 and operating switch 42 all to expose to be arranged on the upper surface that covers 3 main board portion 30 the reseting of count results that the upper surface of this counter 40 is provided with the display part 41 of expression number of times and carries out this display part 41.On the other hand, as shown in Figure 4, on the rear wall 43 of former water pot 4, be formed with the resettlement section 44 of pipe shape along its above-below direction.In this resettlement section 44, contain permanent magnet (not shown), under the state of having accommodated this permanent magnet, upper opening portion tegmentum 45 sealings of resettlement section 44.

Counter 40 has the transmitter (not shown) that detects permanent magnet in the lower face side of lid 3, and the below of this transmitter of permanent magnet crosscut is then detected permanent magnet and passed through once.More particularly, constitute making and cover 3 and slide from the detent position of lid shown in Figure 13 and location of water injection shown in Figure 5, when peristome 17 is opened half degree, promptly cover 3 open to can be fully when supplied water position that former water pot 4 supplies water, permanent magnet is by sensor detecting once.Therefore, no matter be that the supply water method of operation or do not dismantle of dismounting lower cover 3 cover 3 methods that supply water operation, need only and cover 3 by the position of can supplying water, transmitter just detects permanent magnet.In addition, the above-mentioned position of supplying water is not limited to make peristome 17 to open the position of half, covers 3 correct positions that are fully opened from location of water injection as long as be set in.

On the other hand, from dismounting shown in Figure 4 cover 3 state or supplied water position shown in Figure 6 and get back under the situation of location of water injection shown in Figure 5 and detent position shown in Figure 1, permanent magnet is from covering 3 o'clock opposite directions below by transmitter with opening, so counter 40 will be somebody's turn to do by detecting as passing through once.

That is to say, give when supplying water in the former water pot 4, lid 3 is fully opened to the operation of supplying water of the required degree of this water supply, when location of water injection or detent position are returned in the water supply end of job, counter 40 totals detect passing through of twice permanent magnet, counter 40 detect pass through for this twice in, be judged to be and carried out once supplying water, and once count.At this, on above-mentioned water purification cartridge 14, predesignated the number of times that the supplies water reference standard in period as an alternative, when the number of times that the user of above-mentioned pitcher-type water purifier 1 is counted at counter 40 reaches predefined number of times, water purification cartridge 14 is replaced.

Therefore, adopt above-mentioned first example, lid 3 is arranged on the container body 2 sliding freely, therefore compare with Embedded lid in the past, lid 3 is difficult to break away to breaking away from direction because of impact, and, can make during water purification or supply with former water the time in perfusion and cover 3 slips and easily peristome 17 is opened.

Again because lid 3 can be positioned in the position more than 2 places at least, therefore can prevent to cover 3 unwanted the time, slide mobile.

And, when lid 3 opening action and closing movement, lid 3 can be positioned at the position of the water filling port 10 of only opening container body 2, therefore the former water of former water pot 4 can not drain to the outside, and the water purification that can easily only will be stored in the container body 2 are poured out.

Also have, cover in 3, so can confirm the reference standard in replacement period of water purification cartridge 14, so can suppress the unnecessary replacement of water purification cartridge 14 because the counter 40 that the water supply number of times is counted is built in.

Again, compare, adopt the lid 3 that is provided with sliding freely, can reduce that accident such as impact opened and situation about counting, so can improve the reliability of the count results of counter 40 with lid in the past.

And, since detect the opening action that cover 3 water supply usefulness and supply water after the situation of closing movement under ability count as 1 water supply, therefore can not count mistakenly because of a spot of slips such as vibrations, its result, the reliability of the count results of counter 40 can be improved, the replacement cycle of water purification cartridge 14 can be more correctly be familiar with.

In addition, in above-mentioned first example, constitute and adopt permanent magnet covering 3 switching and carry out magnetic detection and the water supply number of times being counted, as long as but can carry out one-time detection because of covering 3 opening action, carry out one-time detection because of closing movement, for example, also can constitute mechanically counting, more particularly, also can be projection to be set in the position that is provided with permanent magnet, can be according to the formation that with respect to twice contact of this projection literal is spiraled then count.Also can carry out electrical treating and show situation about going out by direct contact detection again.

Also have, above-mentioned permanent magnet can be arranged on many places rather than 1 place.Again, also permanent magnet can be installed in and cover on 3, counter 40 is arranged on the container body 2.

And, although understand by step portion B and rear wall and position, give the restraining sense but also can further constitute at the detent position of lid 3 to covering 3 position, forefront.

Below, according to Fig. 7～Figure 13 second example of the present invention is described.

In Fig. 7, the pitcher-type water purifier of symbol 101 expressions second example of the present invention.This pitcher-type water purifier 101 comprises that mainly container body 102, lid 103, so-called former water pot are upper container 104.

Container body 102 forms the barrel shape that the end is arranged that is made of diapire 105, antetheca 106, left and right sides sidewall 107,107 and rear wall 108, and handle 109 is integrally formed with rear wall 108, and is formed with water filling port 110 on the antetheca 106 of the opposition side of handle 109.And antetheca 106, left and right sides sidewall 107,107 and rear wall 108 bight between is separately formed by curved surface, and is equipped with as anti-skidding not shown silicon or elastomerics at least a portion of the bottom surface of the diapire 105 of container body 102.

Water filling port 110 is chevron and forms by the substantial middle on the left and right directions of the upper limb 111 of antetheca 106 part is forwards outstanding, on the antetheca 106 that is formed with this water filling port 110, along with downwards from upper limb 111, the overhang of this water filling port 110 reduces gradually, thereby sees substantial middle portion convergence at the above-below direction of the container body 102 of essentially rectangular shape from cross section.By such formation water filling port 110, between antetheca 106 and upper container 104 (details aftermentioned), form the path of the bottom of leading to container body 102, it is oblique to water filling port 110 inclinations with pitcher-type water purifier 101 to control handle 109, and the water purification that then is stored in the bottom of container body 102 is injected in the outside container etc. by path.

As shown in Figure 8, the upper limb of the left and right sides sidewall 107,107 of container body 102 is parallel to each other, and the outside at the upper limb of this left and right sides sidewall 107,107 is formed with track R ', R ' respectively along its upper limb.This track R ', R ' are side-prominent more outwardly to the bottom more from top, and its cross section is roughly hook-shaped (with reference to Fig. 9).Again, on the substantial middle part of the fore-and-aft direction of the upper limb of left and right sides sidewall, be provided with the otch 107a of mortar shape, by forming this otch 107a, when the upper container 104 that will load and unload the top that is housed in container body 102 is freely pulled down, can easily catch its upper limb, so can easily carry out the dismounting of upper container 104.

Upper container 104 forms its bight by the bottom tube-like that has that curved surface forms, cross-sectional shape is essentially rectangular, and being formed with the hole that is communicated with the bottom of container body 102 on its diapire 112 is interconnecting part 113.And the water purification cartridge 114 of tubular can be arranged on this interconnecting part 113 from the inboard of upper container 104 with loading and unloading, and this water purification cartridge 114 is outstanding downwards from diapire 112 under the state of installing.At this, water purification cartridge 114 has and the upper container 104 interior not shown former water inlets that are communicated with at an upper portion thereof, and its underpart have with container body in the not shown pure water inlet that is communicated with, in the tubular path between former water inlet and pure water inlet, be provided with strainers such as sorbent materials such as gac or hollow fiber membrane, the former water conservancy that flows into from above-mentioned former water inlet flows through path in the water purification cartridge 114 with its deadweight, and discharges downwards from pure water inlet as water purification.

The periphery of the peristome 115 of upper container 104 is provided with the flange part 116 that is bent to form approximate right angle laterally, when the peristome 117 of container body 102 inserts upper containers 104, this flange part 16 is stuck in the peripheral part of the peristome 117 of container body 102, and upper container 104 is fixed on the top of container body 102.

Again, the front side at the periphery of the peristome 115 of upper container 104 is formed with the next door 118 that links to each other and forwards extend with aforesaid flange part 116.The inside of upper container 104 and the water filling port 110 of container body 102 are separated in this next door 118.

And, as shown in figure 10, under upper container 104 is housed in state in the container body 102, leading edge 120 for next door 118,106 upper limb 111 is formed up to after the position that enters slightly to the inside from its left and right sides along antetheca, is formed with to leave the recess 121,121 that upper limb 111 rearward caves in into the mortar shape.And, by the substantial middle of the left and right directions of the leading edge 120 of these recess 121,121 clampings, be formed with upper limb 111 about the forwards outstanding protuberance 122 of the roughly the same shape of profile of central authorities.At this, the upper limb 111 and protuberance 122 arranged spaced of antetheca 106, this space constitutes the peristome 123 of water filling port 110.

On the other hand, on container body 102, loading and unloading are provided with the lid 103 that its peristome 117 is opened and closed freely, and this lid 103 can slide on fore-and-aft direction by above-mentioned track R ', R '.

Lid 103 comprises: main board portion 130; From left border, margo dexter and the posterior lateral margin of this main board portion 130 outstanding formation and surround the left and right sides sidewall 131,131 (diagram only illustrates left side wall 131 among the figure for convenience) and the rear wall (not shown) of the upper limb of the left and right sides sidewall 107,107 of container body 102 and rear wall (with reference to Fig. 7) from the outside downwards; Link to each other with the front portion of main board portion 130 and forwards extend to form, with the profile of the water filling port 110 of container body 102 corresponding before board 133.

Middle body in main board portion 130 has the scarp 134 of direction back lower place inclination in the past, and more caving in than its periphery 135 in the rear portion on this scarp 134, forms recess 136.This recess 136 plays the effect of so-called handle, and to cover 103 be to slide in the rear to opening direction thereby the user can easily make finger hook at this recess 136.

As shown in Figure 9, main board portion 130 from the left and right sides sidewall 131,131 that left and right sides lateral margin extends downwards, be formed with from the outstanding to the inside raised line 137 of its lower edge.And this raised line 137, left and right sides sidewall 131,131 and main board portion 130 constitute cross-sectional shapes and are the roughly recess 138 of U font, this roughly the recess 138 of U font play the effect of groove.At this, recess 138 will be inserted behind above-mentioned track R ' and flange part 116 laminations, make and cover 103 and forwards slide and when being installed on the container body 102 from the rear of container body 102 along track R ', raised line 137 is stuck in the bottom of track R ', has limited to cover 103 to i.e. the moving upward of the direction that breaks away from container body 102.

As shown in figure 10, before board 133 mainly be that peristome 123 to water filling port 110 opens and closes, it links to each other with above-mentioned main board portion 130 and forwards extends to form, and it is that peristome 117 forward shapes are corresponding that the shape of its tip side forms with the shape of described water filling port 110.On the periphery of preceding board 133, be formed with outstanding raised line 139 downwards again.

Again, the rear wall that extends from trailing edge side direction below of main board portion 130 (omitting diagram) covers 103 too under the situation of front slide will making, with the outside surface butt of the rear wall 108 of the peristome 117 of container body 102, by this rear wall, the position, forefront of lid 103 is positioned.

On the other hand, the front portion of peristome 117 peripheries of container body 102 is shaped to stepped, the vertical face of the step portion B ' of this stepped moulding (with reference to Fig. 8) and track R ' orthogonal collocation.That is to say, make and cover 103 when closing direction is the place ahead slip, the front end of the left and right sides sidewall 131,131 of this lid 103 and the vertical face butt of step portion B ' and can't continue forwards to slide, the same with the rear wall of above-mentioned lid 103, the position, forefront of lid 103 is positioned.

Again, thus above-mentioned lid 103 constitutes by making its sliding action that it can also be positioned in the position beyond above-mentioned.More specifically, as shown in Figure 7, lid 103 at first is positioned by the detent position of complete closed at peristome 117, slide if rearward promptly open direction from this position, lid 103 perfusion water purifying location of water injection shown in Figure 11 promptly only the peristome 123 of the water filling port 110 overlapped position of leading edge of opening, cover the protuberance 122 in the leading edge of 103 preceding board 133 and next door 118 be positioned.

At this, the location of above-mentioned location of water injection is to instigate when covering 103 slips to obtain restraining sense (covering the feel that 103 clicks are rattled away and temporarily stopped) in above-mentioned location of water injection.As the mechanism that carries out this location usefulness, as long as can obtain the restraining sense, for example, can constitute: on lid 103, not shown projection or hole are set, on the other hand, on container body 102, be provided with and corresponding not shown hole of projection or hole or the projection of covering 103, make projection and the corresponding hole of this projection chimeric in above-mentioned location of water injection.In addition, at container body 102 or cover and be provided with protuberance on 103, this hole can be arranged on the roughly top of this protuberance.Again, can also haunt is provided with above-mentioned projection freely, utilizes elastic component towards the projected direction application of force.

By such location, make and cover 103 and slide and when carrying out opening action from closing condition, make 103 power of sliding of covering sharply increase and be positioned, cover 103 slips, just can further not carry out opening action if do not make with bigger power in location of water injection shown in Figure 11.And, if make with bigger power and to cover 103 and slide and further to carry out opening action, increased make 103 power of sliding of cover be reduced to increase before equal degree, like this to the words of opening the direction slip, as shown in figure 10, lid 103 just breaks away from from container body 102.In addition, the location of lid 103 is not limited to location of water injection and off-position two places, for example as shown in figure 12, also can position covering 103 in the half-way of unloading lower cover 103 from container body 102.Unloading under the situation about midway positioning of lower cover 103 like this, can prevent to cover 103 because some reason slide arbitrarily and come off from location of water injection.

Yet as shown in Figure 7, the lid 103 of above-mentioned water purification cartridge 114 is provided with the counter 140 of digital display type, and the reference standard in replacement period of water purification cartridge 114 is counted and shown to the switching number of times of 140 pairs of these lids 103 of this counter.At this, this counter 140 is the DYN dynamic counters that driven by the alkaline cell of coin shape, Coin shape or lithium cell etc.

Specifically, as shown in figure 13, this counter 40 forms lamellar, disposes display part 141 and operating switch 142 thereon on the surface.And, by matching, press next operation switch 142 with outpour the water purifying operation from water filling port 110, display part 141 shown numerals are deducted 1, thereby counter 140 plays the effect of so-called down counter.Also have, counter 140 by (for example about 3 seconds) operating switch 142, is reset to initial value with display part 141 shown numerals by long-time.At this, on above-mentioned water purification cartridge 114, predesignated the number of times that the reference standard in the period of replacement promptly supplies water, the initial value of above-mentioned counter 140 is set at the water supply number of times of this water purification cartridge 114.That is, when the user of above-mentioned pitcher-type water purifier 101 becomes " 0 " in the shown numeral of the display part of counter 140, water purification cartridge 114 is replaced.

Again, above-mentioned counter 140 is counted device cover 143 and pushes down from the top, and loading and unloading are fixed on freely and cover on 103.The profile of this counter cover 143 forms in the past direction rear width and becomes big roughly lamellar gradually, and part is formed with on lid 103 and exposes the display part 141 of counter 140 and the window 143a of operating switch 142 in the central.This window 143a is identical with the profile of counter cover 143, and direction rear width becomes big gradually and forms in the past.Also have, at the outstanding respectively fastener 144,144 that is formed with claw-like in the front and back of this counter cover 143.

On the other hand, on lid 103 main board portion 130, be formed with shape corresponding concave part 145 with counter 140.And, around this recess 145, with the corresponding scope of the profile of described counter cover 143 in be formed with the end difference 146 that forms than the low one-level of the upper surface of main board portion 130.At the front and back position of this end difference 146, also be provided with the stop hole 147,147 that card ends the fastener 144,144 of described counter cover 143.At this, counter cover 143 can use resins such as polypropylene, ABS resin.Especially, in order to improve aesthetic appearance, preferably use is covered 103 the identical resin of resin with formation.

And, in that being installed on, counter 140 covers at 103 o'clock, and mounting counter 140 in the recess 145 of lid 103 covers a fastener 144 insertions of counter cover 143 thereafter in 103 the stop hole 147.Make counter cover 143 crooked slightly again, simultaneously another fastener 144 is inserted in another stop holes 147 so that it is protruding upward.Like this, the shape of counter cover 143 returns to the state before crooked, and fastener 144,144 ends with stop hole 147,147 cards respectively, limited counter cover 143 with respect to lid 103 to the displacements that break away from direction.Its result, counter 140 by counter cover 143 from the top push down display part 141 and operating switch 142 around, this counter 140 is clamped in counter cover 143 and covers between 103.

On the other hand, the demounting procedure of counter 140 gets final product with the step opposite with above-mentioned installation, depress the fastener 144 of counter cover 143 from the stop hole 147 that covers 103 inboard, thereby counter cover 143 breaks away from from stop hole 147.Like this, counter cover 143 can break away from from covering 103, can take out counter 140 from recess 145.In addition, in order to be easy to hook pawl etc., for example can be provided with and to form little groove in the left and right side of counter cover 143.

Therefore, adopt above-mentioned second example, the rational replacement cycle that can utilize 140 pairs of loading and unloading of counter to be arranged on the water purification cartridge 114 on the interconnecting part 113 of upper container 104 freely counts, owing to being arranged on freely, counter 140 loading and unloading cover on 103 simultaneously, therefore for example take off from container body 102 and to clean under such situation will covering 103, counter 140 can be pulled down.

Since can pull down counter 140 from covering 103, therefore can lid 103 sum counters 140 are discarded separately respectively when carrying out waste treatment, therefore can reduce the situation that part capable of circulation is handled as non-combustible waste, can alleviate burden to environment.

Also have, cover 103 counter cover 143, so can load and unload and constitute counter 140 freely and improve appearance property owing to be provided with counter 140 is fixed in.That is to say,, can both easily change counter 140 design on every side by the shape that changes counter cover 143 regardless of the shape of counter 140.

And, be presented on the counter 140 as initial value with the corresponding numerical value of the performance of water purification cartridge 114, so the initial setting of counter 140 is easy, and can easily discerns the rational replacement cycle of water purification cartridge 114.

Again, since with the down counter of push button as counter 140, therefore for example compare covering 103 the situation of opening the counter that number of times counts automatically with using, open the counting that causes beyond can preventing to supply water, so can improve the reliability of count results, can replace water purification cartridge with the more rational replacement cycle.

Also have,, so can reduce operating switch 142 by the situation of mishandle because operating switch 142 is configured in the below slightly of cover 103 upper surface.

Again, be provided with, therefore can under the situation that counter 140 can't use because of running down of battery or fault etc., be replaced by new counter 140 because counter 140 loads and unloads freely.

In addition, in above-mentioned second example, cover 103 situation and be illustrated adopting fastener 144,144 that counter cover 143 is fixed in, as long as but can fix easily, be not limited to this.The shape of counter cover 143 also is not limited in the past, and direction rear width enlarges gradually and forms.

Again, being illustrated though counter 140 is formed flat situation, is not under the flat situation at counter 140, as long as covering setting and this shape corresponding concave part 145.

Also have, in above-mentioned example, counter 140 is illustrated for the situation by battery-driven electric, but also can adopts mechanical counter.

And, in the above-mentioned example, be illustrated covering 103 situations that are provided with sliding freely, as long as but can close freely, be not limited to sliding type.

Again, in the above-mentioned example, be illustrated with main board portion 130 direct-connected situations,, also can liner be set for example covering between 103 main board portion 130 and the flange part 116 in order to prevent to cover 103 breakages etc. to covering 103.

Utilizability on the industry

Adopt the present invention, because cap is arranged on the peristome of vessel sliding freely, therefore Embedded with in the past Lid is compared, and can suppress to cover the situation that breaks away from from vessel because impacting, and can also peristome be opened. Again, by At least be positioned the position more than 2 places in cap, therefore can prevent cap sliding in unnecessary.

Because counter can be pulled down from cap, therefore when carrying out waste treatment, the cap sum counter can be given up separately respectively again, Abandon, therefore can reduce the situation that part capable of circulation is processed as non-combustible waste, can alleviate the burden to environment.
