Introduction to buried water supply installation
Under the environment such as rural area, field, do not have supporting special water supply system (like municipal water supply line), therefore bury formula water supply installation among the prior art and be difficult to realize the moisturizing. In view of this, a first aspect of the present invention provides a buried water supply apparatus having a simple structure and convenient installation, which can implement manual water replenishment and can rapidly supply a predetermined amount of water to a target object by a human.
The water supply device of the present invention is particularly suitable as a water supply member for a toilet, but it can be used as a water supply member for other types of flushing and showering apparatuses.
The underground water supply device provided by the invention is exemplarily described by two embodiments.
Fig. 1 to 2 are schematic structural views of an underground water supply device 10 according to a first embodiment of the present invention in two working states.
As shown in fig. 1 to 2, the underground water supply device 10 in the present embodiment includes a water storage tank 11, a water supply tank 12, a telescopic barrel 13, a water supply pipe 14, a water injection pressure rod 15, and other components. Wherein:
the water supply pool 12 is arranged in the water storage pool 11, the top of the water supply pool 12 extends upwards to form the water storage pool 11, and the side wall of the water supply pool 12 is provided with a water replenishing hole 16 for communicating the water storage pool 11 with the water supply pool.
The telescopic barrel 13 is arranged in a water supply pool, the inner cavity of the telescopic barrel 13 forms a water supply cavity with variable volume, the bottom of the telescopic barrel 13 is provided with a water inlet, the water inlet is provided with a first one-way check valve 17, and the first one-way check valve 17 is used for enabling water to flow into the inner cavity of the telescopic barrel 13 from the outer side of the telescopic barrel 13 through the water inlet in a one-way mode.
The lower extreme of feed pipe 14 is connected and is penetrated the inner chamber to flexible bucket 13 downwards at the roof of flexible bucket 13, and the upper end of feed pipe 14 upwards extends water supply pool 12, is provided with one-way check valve 18 of second on the feed pipe 14, and one-way check valve 18 of second is used for making water from the inner chamber of flexible bucket 13 one-way through feed pipe 14 and through the upper end outflow of feed pipe 14 in order to realize the feedwater.
The water injection depression bar 15 is hollow structure, and the lower extreme of water injection depression bar 15 is connected on the roof of flexible bucket 13, and the upper end of water injection depression bar 15 upwards extends to give water tank 12, and the upper end of water injection depression bar 15 is provided with the water filling port that is used for the moisturizing, then is provided with the delivery port that feeds through water injection depression bar 15 and give water tank 12 on the lateral wall of water injection depression bar 15, and water injection depression bar 15 can reciprocate in vertical direction to the realization is to the oppression of flexible bucket 13.
In this embodiment, the telescopic barrel 13 forms a water supply mechanism of the buried water supply device 10, and the water injection pressure rod 15 forms a water supply driving mechanism which can drive the telescopic barrel 13 to compress, so as to supply water, specifically:
when the inner cavity of the telescopic barrel 13 is filled with water, and the water injection pressure rod 15 is pressed to move downwards and press the telescopic barrel 13 downwards when the water injection pressure rod 15 is pressed downwards, so that the telescopic barrel 13 is contracted to a contracted state shown in fig. 2. In this process, the water in the telescopic tub 13 rushes the second one-way check valve 18 outward and rapidly flows out through the second end of the water supply pipe 14, thereby achieving water supply. Of course, the first one-way check valve 17 is kept closed all the time during the water supply.
After the water supply is finished, the water injection pressure rod 15 is released, and the telescopic barrel 13 rebounds to the reset state shown in fig. 1. In the process, the inner cavity of the telescopic barrel 13 is under negative pressure, the first one-way check valve 17 is flushed, and water outside the telescopic barrel 13 enters the inner cavity of the telescopic barrel 13 through the water inlet and finally fills the telescopic barrel 13.
Therefore, the water supply operation can be realized by manually pressing or releasing the water injection pressure rod 15, so that the implementation cost of the water supply device is reduced.
At the moment of releasing the water injection pressure lever 15, the inside of the telescopic tub 13 is instantaneously brought into a negative pressure, and the second one-way check valve 18 is instantaneously closed, so that the water in the water supply pipe 14 between the second one-way check valve 18 and the telescopic tub 13 does not reach the inside of the telescopic tub 13 and is held in the water supply pipe 14. In this way, in the next water supply operation, the water stored in the water supply pipe 14 can be immediately flushed out through the second end of the water supply pipe 14 while the telescopic barrel 13 is compressed and contracted, so that the water supply process of the water supply pipe 14 is shortened, namely the water supply response time is shortened. It can be seen that the second one-way check valve 18 provided on the water supply pipe 14 not only enables one-way flow of water, but also shortens the water supply stroke of the water supply pipe 14.
Preferably, in order to ensure that the telescopic barrel 13 can be smoothly rebounded to the reset state after pressure loss, a reset spring (not shown) may be installed in the telescopic barrel 13, and an upper end of the reset spring is connected to a top wall of the telescopic barrel 13 and a lower end of the reset spring is connected to a bottom of the telescopic barrel 13. When flexible bucket 13 pressurized shrink, reset spring contracts in step, and when flexible bucket 13 decompression, thereby reset spring-backed resets and drives flexible bucket 13 and kick-backed resets. Of course, in other embodiments, the return spring may be disposed outside the telescopic barrel 13.
Because the upper end of the water injection compression bar 15 is provided with a water injection port for water supplement, the side wall of the water injection compression bar 15 is provided with a water outlet 152 for communicating the water injection compression bar 15 and the water supply tank 12. And a water replenishing hole 16 for communicating the water storage tank 11 and the water supply tank 12 is arranged on the side wall of the water supply tank 12. Therefore, when the amount of the stored water in the water storage tank 11 is insufficient, water can be injected into the water injection pressure rod 15 through the water injection port at the upper end of the water injection pressure rod 15, and the injected water enters the water storage tank 11 through the water outlet 152 and the water replenishing hole 16, so that the water is replenished into the water storage tank 11. Therefore, on the premise of no water supply system, the buried water supply device 10 in the embodiment can also realize rapid water supply, so that the use requirements in rural areas, fields and other environments are met.
Preferably, the water injection pressure lever 15 is opened at the top to form the water injection port, and an openable top cover 151 is provided at the water injection port. When water needs to be supplemented, the top cover 15 is opened, and the water filling port can be exposed.
Generally, the water reservoir 11 of the buried water supply system 10 in this embodiment is buried under the frozen soil layer, and the top of the water reservoir 22 and the upper portion of the water injection pressure bar 15 are exposed to the ground. The specific dimensions of the reservoir 11, the feed reservoir 22, and the water injection plunger 15 are adjusted according to actual needs, and are not limited in this embodiment.
Since the main body of the buried water supply device 10 is buried underground, for convenience of installation and maintenance, it is preferable that the top of the water supply tank 12 is opened to form a pick-and-place opening, the pick-and-place opening is covered with a detachable cover 121, and the cover 121 is provided with a first through hole for the water injection pressure rod 15 to pass through and a second through hole for the water supply pipe 14 to pass through. The outer diameter of the water injection pressure lever 15 is slightly smaller than the hole of the first through hole.
By providing the opening, when maintenance of the telescopic barrel 13, the water injection pressure lever 15, the first one-way check valve 17, the water supply pipe 18 and other parts is required, the cover 121 is opened to expose the opening, and the parts can be taken out from the water supply tank 12. After maintenance is completed, the above components can be placed back into the water supply tank 12 through the access opening. Thus, the installation and maintenance work of the invention is greatly facilitated.
Because the lower end of the water supply pipe 14 is connected to the top wall of the telescopic barrel 13, the water supply pipe 14 is bound to be pulled by the telescopic barrel 13 along with the contraction of the telescopic barrel 13 in the water supply process. In some applications, the upper end of the water supply pipe 14 is fixedly connected to the target object to be supplied with water. In order to prevent the upper end of the water supply pipe 14 from being pulled off during the water supply process, it is preferable that the water supply pipe 14 is fixedly fitted to the second through hole, so that the portion of the water supply pipe 14 above the cover 121 is not pulled by the telescopic tub 13.
In order to prevent the portion of the water supply pipe 14 under the cover 121 from being pulled, the portion of the water supply pipe 14 under the cover 121 is configured to be stretchable. For example, in some embodiments, the water supply pipe 14 is a bendable flexible pipe, and when the water supply pipe 14 is assembled, the length of the portion of the water supply pipe 14 below the cover 121 is set to be at least equal to the distance from the top wall of the telescopic barrel 13 to the cover 121 when the telescopic barrel 13 is in a fully compressed state. Thus, when the telescopic barrel 13 is in the rebound reset state, the part of the water supply pipe 14 under the cover 121 is in the bending state shown in fig. 1, and when the telescopic barrel 13 is in the compression state, the part of the water supply pipe 14 under the cover 121 is in the stretching state shown in fig. 2. Namely: the water supply pipe 14 is located below the cover 121 and can be freely stretched and bent along with the compression and rebound of the telescopic barrel 13.
The second embodiment of the present invention provides an underground watering device 20 of another structure,
fig. 3 to 4 show the underground water supply system 20 in two operating states. As shown in fig. 3 and 4, the underground water supply device 20 in the present embodiment includes a reservoir 21, a water supply tank 22, a piston 23, a water supply pipe 24, and a water injection pressure rod 25. Wherein:
the water supply pool 22 is arranged in the water storage pool 21, the top of the water supply pool 22 extends upwards to form the water storage pool 21, and the side wall of the water supply pool 22 is provided with a water replenishing hole 26 for communicating the water storage pool 21 with the water supply pool.
The piston 23 is arranged in the water supply tank 22 and is positioned below the water replenishing hole 26, and the piston 23 is tightly attached to the side wall of the water supply tank 22 and can slide up and down along the side wall of the water supply tank 22. The piston 23, the side wall of the water supply pool 22 positioned below the piston 23 and the bottom of the water supply pool 22 form a water supply cavity with variable volume. The side wall of the feed tank 22 is provided with a water inlet located below the piston 23, preferably near the bottom of the feed tank 22. The water inlet is provided with a first one-way check valve 27, and the first one-way check valve 27 is used for enabling water to flow into the water supply cavity from the water storage tank 21 in one way through the water inlet.
The lower end of the water supply pipe 24 is connected to the piston 23 and penetrates through the piston 23 downwards to enter the water supply cavity, the upper end of the water supply pipe 24 extends upwards to form the water supply pool 22, the water supply pipe 24 is provided with a second one-way check valve 28, and the second one-way check valve 28 is used for enabling water to pass through the water supply pipe 24 from the water supply cavity in one way and flow out from the upper end of the water supply pipe 24.
The water injection pressure lever 25 is of a hollow structure, the lower end of the water injection pressure lever 25 is connected to the piston 23, the upper end of the water injection pressure lever 25 extends upwards to form the water supply tank 22, a water injection port for water supplement is formed in the upper end of the water injection pressure lever 25, a water outlet 252 communicated with the water injection pressure lever 25 and the water supply tank 22 is formed in the side wall of the water injection pressure lever 25, and the water injection pressure lever 25 can move up and down in the vertical direction so as to drive the piston 23 to move up.
It can be seen that the buried water supply device 20 in the present embodiment has substantially the same structure as the buried water supply device 10 in the first embodiment, and there is a main difference that, in the present embodiment, the piston 23 constitutes a water supply mechanism of the buried water supply device 20. Specifically, the method comprises the following steps:
when the water injection pressure lever 25 is pressed downward, the water injection pressure lever 25 is pressed to move downward and presses the piston 23 downward, thereby moving the piston 23 downward in synchronization. In the process, water in the water supply cavity below the piston 23 flushes the second one-way check valve 28 outwards and flows out rapidly through the second end of the water outlet pipe 24, thereby realizing water supply. Of course, the first one-way check valve 27 remains closed at all times during this watering process.
After water supply is completed, the water injection pressure rod 25 is pulled upwards to drive the piston 23 to move upwards to the reset position. In the process, the water supply cavity under the piston 23 becomes negative pressure, the first one-way check valve 27 is flushed, and the water in the water storage tank 21 enters the water supply cavity under the piston 23 through the water inlet to prepare for next water supply.
In order to achieve smooth return of the piston 23, it is preferable that a return spring (not shown) is installed in the water supply chamber, and an upper end of the return spring is connected to the piston 23 and a lower end thereof is connected to a bottom of the water supply tank 22. When the pressure-applied piston 23 moves downward, the return spring contracts in synchronization. When the piston 23 loses pressure, the return spring rebounds and returns to drive the piston 23 to move upwards to return. Of course, in other embodiments, the return spring may be disposed outside the feed chamber, such as between the piston 23 and the top wall of the feed reservoir 22.
As in the first embodiment, since the upper end of the water injection pressure lever 25 is provided with a water injection port for supplying water, the side wall of the water injection pressure lever 25 is provided with a water outlet 252 communicating the water injection pressure lever 25 and the water supply tank 22. And a water replenishing hole 26 for communicating the water storage tank 21 and the water supply tank 22 is formed in the side wall of the water supply tank 22. Therefore, when the amount of the stored water in the water storage tank 21 is insufficient, water can be injected into the water injection pressure rod 25 through the water injection port at the upper end of the water injection pressure rod 25, and the injected water enters the water storage tank 21 through the water outlet 252 and the water replenishing hole 26, so that water is replenished to the water storage tank 21.
Preferably, the water injection pressure lever 25 is opened at the top to form the water injection port, and an openable top cover 251 is provided at the water injection port. When water is needed to be supplemented, the top cover 25 is opened, and the water filling port can be exposed.
As in the first embodiment, it is preferable that the top of the water supply tank 22 is opened to form an access opening, the access opening is covered with a detachable cover 221, and the cover 221 is provided with a first through hole through which the water injection pressure lever 25 passes and a second through hole through which the water supply pipe 24 passes. The outer diameter of the water injection pressure lever 25 is slightly smaller than the hole of the first through hole.
The piston 23, the water injection pressure lever 25, the first one-way check valve 27, the water supply pipe 24 and other parts can be installed and maintained through the taking and placing port.
In order to prevent the upper end of the water supply pipe 24 from being pulled off during the water supply, it is preferable that the water supply pipe 24 is fixedly fitted to the second through hole, so that the portion of the water supply pipe 24 above the cover 221 is not pulled by the telescopic tub 13, as in the first embodiment.

As described hereinbefore, the buried water supply device provided by the first aspect of the present invention is particularly suitable as a water supply part of a toilet bowl. The invention provides a toilet bowl, wherein the buried water supply device provided by the first aspect of the invention is integrated.
The following will describe the specific structure and operation principle of the toilet by two embodiments.
As shown in fig. 5, a toilet according to a third embodiment of the present invention includes a toilet main body 30 and a water supply device. Wherein, the toilet body 30 is provided with a toilet. The water supply device is used for supplying water to the urinal so as to flush dirt in the urinal or store water seal in the urinal.
The water supply device in this embodiment is the buried water supply device 10 in the first embodiment, and the second end of the water outlet pipe 14 of the buried water supply device 10 is connected to the urinal body 30 and is communicated with the urinal.
When water needs to be supplied to the urinal, the water injection pressure rod 15 of the buried water supply device 10 is pressed downwards, and the buried water supply device 10 flushes water into the urinal. For a specific water supply process, please refer to the related contents of the first embodiment, which is not described herein again.
As described above, in the case of the underground type water supply apparatus 10, the inside of the telescopic tub 13 becomes a negative pressure at the moment of releasing the water injection pressure lever 15, and the second one-way check valve 18 is closed at the moment, so that the water in the water supply pipe 14 between the second one-way check valve 18 and the telescopic tub 13 does not have time to return to the inside of the telescopic tub 13, thereby being held in the water supply pipe 14. Thus, in the next water supply operation, the water stored in the water supply pipe 14 can be flushed out through the second end of the water supply pipe 14 first, which is equivalent to shortening the water supply stroke of the water supply pipe 14, namely shortening the water supply response time.
However, when the temperature of the surrounding environment in which the toilet is located is below zero, the outlet pipe 14 is exposed to the ground and the water held therein is easily frozen, resulting in a failure of the water supply. In view of this, it is preferable. The second end of the outlet pipe 14 is removably connected to the urinal body 30 and the second one-way check valve 18 is removably disposed within the supply pipe 14 proximate the second end of the supply pipe 14.
When the temperature of the surrounding environment is low, after the water supply to the toilet is completed, the second end of the water supply pipe 14 is pulled out from the toilet body 30 and the second one-way check valve 18 is taken out, after the water in the water supply pipe 14 flows back to the telescopic barrel 13, the second one-way check valve 18 is installed back into the water supply pipe 14, and the second end of the water supply pipe 14 is connected back to the toilet body 30 again.
Of course, in other embodiments, the toilet of the present invention may also adopt the buried water supply device 20 of the second embodiment of the present invention as a water supply device for the toilet. As shown in fig. 6, a toilet stool provided by a fourth embodiment of the present invention is shown, the toilet stool adopts the buried water supply device 20 in the second embodiment as a water supply component, and the structure and the water supply process of the buried water supply device 20 refer to the corresponding contents of the second embodiment in the foregoing, and are not repeated here.
The invention has been described above with a certain degree of particularity. It will be understood by those of ordinary skill in the art that the description of the embodiments is merely exemplary and that all changes that come within the true spirit and scope of the invention are desired to be protected. The scope of the invention is defined by the appended claims rather than by the foregoing description of the embodiments.
