Handheld shower head filter special warning update device

The invention relates to a "handheld shower head grip filter special warning update device", which belongs to the innovative application field of the hand-held shower head, and can be installed in a hand-held shower head with a grip filter handheld hand-held shower head Between the grip filter and the grip filter, in addition to the function of metering the shower water passing through the grip filter and providing an early warning update, it is possible to achieve a balance of center of gravity between the hand-held shower head and the grip filter, and It is not necessary to detach the hand-held shower head and the grip filter from each other when charging.

It is well known that the tap water supplied by the waterworks will be added with chlorine to sterilize, and the residual chlorine in the tap water will form a carcinogenic trihalomethane. Therefore, the bathing hot water that people touch with the shower every day will cause the hair to break and dry. Shedding, discoloration, and skin irritability, itching, dryness, peeling, etc., therefore, in order to remove the residual chlorine in the shower bath hot water, the hand shower shower head design disclosed in US Pat. No. 6,016,977 is in the shower head. The hand grip is built into a filter element that can absorb residual chlorine in the water, and a commercially available product with a grip filter hand-held shower head is commercially available. The structure is shown in Figure 1 to Figure 3. The hand-held shower head 1 and a grip filter 70 are formed. The female pipe thread 72 of the water outlet 71 of the grip filter 70 is screwed onto the male pipe thread 3 of the water inlet 2 of the hand-held shower head 1, and the inside is filled with active A filter material 75 such as activated carbon or calcium sulfite (CaSO3) allows the residual chlorine flowing through the shower water W in the grip filter 70 to be adsorbed or removed, thereby providing a hand-held shower Head 1 can be covered by a cover The water spray hole 5 of 4 sprays shower water W without residual chlorine (as shown in Figs. 2 and 3).

The activated carbon or calcium sulfite filter 75 used in the above-mentioned grip filter 70 for adsorbing or removing residual chlorine in the hot water of the bath has a certain filtration service life, and generally produces a filter material such as activated carbon or calcium sulfite 75. The manufacturer will indicate the service life of the filtered total water flow on the filter material 75, such as 300 gallons or 500 gallons, so if the total filtered water flow life value of the grip filter 70 is For 300 gallons, when the total amount of filtered water reaches 300 gallons, the new grip filter 70 must be replaced, otherwise the effect of removing residual chlorine in the hot water of the bath will be lost. The cumulative amount of water flowing through the shower water W in the grip filter 70 is the life value of the filtered total water flow. If it is replaced before the life value is reached, it will cause premature expenditure to purchase a new grip filter. The cost of 70 (because it still has the effect of dechlorination), but it will waste and increase the economic burden of the user. If it is replaced after the life value is exceeded, it will use the shower water that is filtered out by the chlorine removal effect. W, and the body's skin is affected Injury.

The above-mentioned other hand-held shower head with a grip filter update warning device (i.e., the Republic of China invention patent publication No. 201406337 and the US invention patent publication No. US2014/0042240) is manufactured by the inventor of the present invention and countless times. After the actual use of the test, it can indeed achieve the expected efficacy, but also found that there are several missing as follows:

1. As shown in FIG. 4, FIG. 10, FIG. 20, FIG. 21 and FIG. 1, the warning box 20 is inserted into the back surface 12 of the shower head 10, and the LCD data display element is placed inside the warning box 20. 32 and the rechargeable battery 33, and the impeller 40 and the upper cover 50 are also placed in the impeller seat 18 of the shower head 10, so that the total weight of the shower head 10 after assembly is greater than that of the conventional filter shown in FIG. The hand-held shower head 1 has a heavier weight, so that the center of gravity of the hoe is heavy and uneven. When the shower is accidentally or slipped during the shower, the grip filter 70 is removed from the hand grip. When holding, it is easy to cause the heavy weight of the shower head 10 to hit the ground first, and cause displacement or poor contact between the internal components to different degrees of damage, if the shower head 10 hits the ground due to hand slippage When the number of times is too high, the most serious damage will result in the loss of the original 〝 metering display and the warning function of the shower head 10.

2. As shown in FIG. 25 to FIG. 28, each time the rechargeable battery 33 in the alarm box 20 needs to be charged, the warning box body 20 and the recessed seat 122 on the back surface 12 of the shower head 10 must be separated from each other. After the electric power, the warning box body 20 must be placed into the recessed seat 122 of the back surface 12 of the shower head 10 again. After the number of repeated operations is excessive, the elasticity of the recessed seat 122 in the head body 10 is easily caused. The cassette 124 is elastically deformed or broken, resulting in a shortened service life of the entire shower head 10 and an increase in the cost of the early purchase of the shower consumer.

3. For consumers who are currently using the hand-held showerhead with the grip filter shown in Figure 1, if they want to avoid premature or delayed replacement of the grip filter and affect their health, they want to choose In another conventional product of the "handheld shower head with a grip filter update warning device" as shown in FIG. 4, it must completely discard the original hand-held shower head with a grip filter, and then purchase it separately. The "handheld shower head with grip filter update warning device" can be realized. Therefore, the discarded handle has a grip filter.

It can be fixed with the pipe thread of the conventional grip filter outlet, and a water flow passage is formed between the upper joint portion of the top surface and the lower joint portion of the bottom surface, and the water flow passage intersects the bottom surface. Further, an impeller seat accommodating chamber is disposed in the inner recess, and the impeller seat sleeved with the impeller can be inserted, and the shower water passing through the conventional grip filter can be metered and displayed, and the warning is updated. Knowing between the hand-held shower head and the grip filter The balance of the center of gravity causes the showerer to accidentally or hand-slip. When the grip filter is removed from the hand and hits the ground, it does not occur as another known Chinese invention patent disclosure. No. 201406337 "Hand-held shower head with grip filter update warning device", the heavy-weight shower head hits the ground first, resulting in a loss of displacement or poor contact between the internal components.

Another object of the present invention is to provide an "early warning update device for a hand-held shower head grip filter", wherein a charging socket is recessed on one end surface of each of the two end faces of the main body, and a rubber is disposed on the charging socket. The socket waterproof cover of the material, when the rechargeable battery in the signal circuit device is gradually exhausted and needs to be charged, it is not necessary to first detach the body from the conventional hand-held shower head and the grip filter, and only need to open the body side end face. The socket waterproof cover can directly insert the conventional charging connector into the charging socket to complete the charging, so the operation of charging is also better than another conventional Chinese inventor patent number 201406337 "with grip filter update" The hand-held shower head of the warning device is simple and fast.

Still another object of the present invention is to provide an "early warning update device for a hand-held shower head grip filter". Since the upper joint portion and the lower joint portion of the body of the present invention can respectively have a grip filter with a conventional gripper The hand-held showerhead of the hand-held showerhead is fixed to the grip filter, so for consumers who are currently using the hand-held showerhead with the grip filter, in order to avoid premature or delayed replacement Holding the filter to affect its health, and if you want to choose the function of the grip filter to update the warning device, you don't have to give up the original hand-held shower head with the grip filter, just buy the product of the invention and install it on it.
