[0018] Beneficial Effects

[0019] The present invention has the following beneficial effects:

[0020] (1) The jet constant pressure variable frequency water supply system is provided with a waterproof motor, a cross rod, a connecting piece and a cleaning brush. The threaded rod moves the moving rod under the action of the driving motor, thereby driving the moving box to move. The waterproof motor can rotate the cross rod through the output shaft. The cross rod can enable the cleaning brush to clean the inner wall of the water tank through the connecting piece. Under the action of the transmission mechanism, the moving box can drive the waterproof motor to move, so that the water tank can be cleaned in all directions, which solves the problem that after long-term use, some impurities such as rust will appear on the inner wall of the water storage device, and the existing water outlet device is inconvenient to clean, resulting in the possibility of more bacteria in the internal water source, causing water resource pollution and affecting user health.

[0021] (2) The jet constant pressure variable frequency water supply system is provided with a T-shaped rod, a buffer spring, a pressure sensor and a cleaning plate. When the cross rod rotates, the cross rod can drive the cleaning plate to rotate through the T-shaped rod. Under the action of the moving box, the cleaning plate will contact the side wall inside the water tank. The cleaning plate can clean the left and right sides of the inner wall of the water tank and completely clean the water tank. After the cleaning plate contacts the side wall of the water tank, the moving box will continue to move a distance. During this process, the buffer spring is stretched to play a buffering role, so that the cleaning plate can always contact the inner wall of the water tank without affecting the movement of the moving box, so that the cleaning plate can contact the inner wall of the water tank for a longer time.

[0022] (3) The jet constant pressure variable frequency water supply system is provided with a first filter and a second filter. The first filter can perform the first filtration before the water enters the water tank to prevent larger particles of impurities from entering the water tank, which would cause inconvenience in cleaning later. When the water is supplied by the pressure-stabilizing pump, the second filter can prevent other impurities such as water rust that may exist in the water tank from entering the pressure-stabilizing pump and affecting its operation.

[0023] (4) The jet constant pressure variable frequency water supply system is provided with a protective shell, a sound absorbing panel and a radiator. The protective shell can protect the pressure stabilizing pump and prevent the pressure stabilizing pump from being exposed to the outside for a long time and being susceptible to corrosion. The sound absorbing cotton can absorb the noise generated by the operation of the pressure stabilizing pump and reduce the noise. The radiator can discharge the heat generated by the pressure stabilizing pump in time and prevent the temperature of the pressure stabilizing pump from being high and affecting normal operation.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] See also Figure 1-Figure 5 The embodiment of the present invention provides a technical solution: a jet constant pressure variable frequency water supply system, comprising a water tank 1, the bottom of the water tank 1 is connected to a pressure-stabilizing pump 3 through a water outlet pipe 2, the surface of the water tank 1 is connected to a driving motor 4, and the interior of the water tank 1 is provided with a moving box 6 through a transmission mechanism 5, and the transmission mechanism 5 is used to drive the moving box 6;

[0034] A waterproof motor 7 is arranged inside the mobile box 6, and a cleaning component 8 is arranged on the surface of the output shaft of the waterproof motor 7. The cleaning component 8 is used to clean the inner wall of the water storage tank 1. A sewage outlet is arranged at the bottom of the water storage tank 1.

[0035] Specifically, the transmission mechanism 5 includes a threaded rod 501, a pulley 502 and a movable rod 503, one end of the threaded rod 501 is connected to the output shaft of the driving motor 4, the other end of the threaded rod 501 passes through the water tank 1 and is movably connected to the inner wall of the water tank 1, the movable rod 503 is threadedly sleeved on the surface of the threaded rod 501, the threaded rod 501 and the pulley 502 are both set to two, and the two pulleys 502 are connected by belt transmission.

[0036] In the present embodiment, the threaded rod 501, the pulley 502 and the moving rod 503 are all set in two, the threaded rod 501 passes through the water tank 1 and extends to the inside of the water tank 1, and is movably connected thereto, the driving motor 4 is connected to one of the threaded rods 501, and the pulley 502 is fixedly sleeved on the surface of the threaded rod 501. When the driving motor 4 drives one threaded rod 501 to rotate, the pulley 502 connected thereto will also rotate synchronously, and the pulley 502 drives another pulley 502 to rotate through the belt, thereby causing the other threaded rod 501 to rotate as well. The synchronous rotation of the two threaded rods 501 can cause the two moving rods 503 to move synchronously, so that the moving box 6 can move stably, and the moving rod 503 can play a supporting role to support the cross rod 801 and the cleaning plate 12.

[0037] Specifically, the moving rod 503 is in a T-shape, one end of the moving rod 503 is connected to the surface of the moving box 6 , and the surface of the moving rod 503 is movably connected to the inner wall of the water tank 1 .

[0038] In this embodiment, the movable rod 503 is T-shaped, and a T-shaped groove matching the movable rod 503 is provided on the inner wall side of the water tank 1, so that the movable rod 503 can be snapped into the inside of the water tank 1, limiting and guiding the movable rod 503, making the movement of the movable rod 503 smoother, and the T-shaped groove can also support the movable rod 503.

[0039] Specifically, the cleaning assembly 8 includes a cross rod 801 and a cleaning brush 802. The cross rod 801 is fixedly sleeved on the surface of the output shaft of the waterproof motor 7. The cleaning brush 802 is elastically connected to the cross rod 801 through a connecting piece 803. The surface of the cleaning brush 802 is movably connected to the inner wall of the water tank 1.

[0040] In this embodiment, a placement groove is provided at the end of the cross rod 801, and the connecting piece 803 is elastically inserted into the inside of the placement groove. The cleaning brush 802 is fixedly connected to the surface of the connecting piece 803. The cross rod 801 will rotate under the action of the output shaft of the waterproof motor 7. The cross rod 801 drives the cleaning brush 802 to rotate through the connecting piece 803. The cleaning brush 802 will always fit the inner wall of the water tank 1 to clean the inner wall of the water tank 1. At the same time, under the action of the transmission mechanism 5, the moving box 6 will drive the waterproof motor 7 to move, and then the cross rod 801 will indirectly drive the cleaning brush 802 to move, so that it can rotate around the central axis of the waterproof motor 7 to comprehensively clean the inner wall of the water tank 1.

[0041] Specifically, the surface of the connecting member 803 is connected to a limit spring 9, one end of the limit spring 9 is fixedly connected to the inner wall of the cross rod 801, the surface of the connecting member 803 is movably connected to the inner wall of the cross rod 801, and the shape of the connecting member 803 is T-shaped.

[0042] In this embodiment, the limit spring 9 is in a compressed state, which can make the connecting piece 803 tend to move toward the inner wall of the water tank 1, so that the cleaning brush 802 can always maintain contact with the inner wall of the water tank 1, and can avoid hard contact between the cleaning brush 802 and the inner wall of the water tank 1, thereby preventing the inner wall of the water tank 1 from being scratched. The connecting piece 803 is T-shaped, and a movable limit ring is sleeved on its surface, and the limit ring is fixedly connected to the end of the cross rod 801, which can limit the connecting piece 803 and facilitate installation.

[0043] Specifically, the surface of the cross rod 801 is elastically connected to a T-shaped rod 11 via a buffer spring 10 , and one end of the T-shaped rod 11 passes through the cross rod 801 and is connected to the surface of the cleaning plate 12 .

[0044] In this embodiment, one end of the buffer spring 10 is fixedly connected to the surface of the cross rod 801, and the other end is fixedly connected to the surface of the T-shaped rod 11. One end of the T-shaped rod 11 movably passes through the cross rod 801, and the cross rod 801 is fixedly connected to the cleaning plate 12. When the cross rod 801 rotates, the cross rod 801 can drive the cleaning plate 12 to rotate through the T-shaped rod 11. Under the action of the movable box 6, the cleaning plate 12 will contact the side wall inside the water tank 1. The cleaning plate 12 can clean the left and right sides of the inner wall of the water tank 1 and comprehensively clean the water tank 1. After the cleaning plate 12 contacts the side wall of the water tank 1, the movable box 6 will continue to move an end distance. During this process, the buffer spring 10 is stretched, which can play a buffering role, so that the cleaning plate 12 can always contact the inner wall of the water tank 1 without affecting the movement of the movable box 6, so that the cleaning plate 12 can contact the inner wall of the water tank 1 for a longer time.

[0045] Specifically, the cleaning plate 12 is arc-shaped, and a pressure sensor 13 is provided on a side of the cleaning plate 12 close to the waterproof motor 7 .

[0046] In the present embodiment, the shape of the arc plate is set to be an arc, which is compatible with the shape of the inner wall of the water tank 1. When the cleaning plate 12 cleans the inner wall of the water tank 1, the moving seat drives the waterproof motor 7 to move in the direction close to the pressure sensor 13. When the output shaft of the waterproof motor 7 contacts the pressure sensor 13, the control system is activated to reverse the drive motor 4, and then the moving box 6 moves in the opposite direction, thereby cleaning the inner wall of the water tank 1 multiple times.

[0047] Specifically, a protective shell 14 is disposed on the surface of the voltage-stabilizing pump 3 , a sound-absorbing panel 15 is connected to the inner wall of the protective shell 14 , and a radiator 16 is also disposed on the surface of the protective shell 14 .

[0048] In this embodiment, the protective shell 14 can protect the voltage-stabilizing pump 3 and prevent the voltage-stabilizing pump 3 from being exposed to the outside for a long time and being easily corroded. The sound-absorbing cotton can absorb the noise generated by the voltage-stabilizing pump 3 during operation to reduce the noise. The radiator 16 can discharge the heat generated by the voltage-stabilizing pump 3 in time to prevent the temperature of the voltage-stabilizing pump 3 from being high and affecting normal operation.

[0049] Specifically, a first filter screen 17 is provided at the water inlet of the water storage tank 1 , and a second filter screen 18 is provided at the connection between the water storage tank 1 and the water outlet pipe 2 .

[0050] In this embodiment, the first filter 17 can perform the first filtration before the water enters the water tank 1 to prevent larger particles of impurities from entering the interior of the water tank 1, causing inconvenience in cleaning later. When water is supplied by the pressure-stabilizing pump 3, the second filter 18 can prevent other impurities such as water rust that may exist in the water tank 1 from entering the interior of the pressure-stabilizing pump 3 and affecting the operation of the pressure-stabilizing pump 3.

[0051] Specifically, a waterproof bearing 19 is sleeved on the surface of the output shaft of the waterproof motor 7 , and the surface of the waterproof bearing 19 is connected to the inner wall of the moving box 6 .

[0052] In this embodiment, the waterproof bearing 19 is sleeved on the output shaft of the waterproof motor 7, and its surface is fixedly connected to the inner wall of the moving box 6, which can prevent the water inside the water tank 1 from entering the interior of the moving box 6, causing the waterproof motor 7 to be soaked in water for a long time, which may shorten the service life of the waterproof motor 7.

[0053] When in use, first inject water into the water tank 1 from the water inlet of the water tank 1, the water will pass through the first filter 17 to filter out larger particles of impurities that may be contained in the water to prevent them from entering the water tank 1. When water supply is needed, the pressure-stabilizing pump 3 is started to pump out the water in the water tank 1, and the water in the water tank 1 will pass through the second filter 18 to filter again to prevent other impurities such as rust that may exist in the water tank 1 from entering the pressure-stabilizing pump 3, which may cause damage to the pressure-stabilizing pump 3. The protective shell 14 can protect the pressure-stabilizing pump 3. During the operation of the pressure-stabilizing pump 3, it will generate more heat and louder noise. The radiator 16 can dissipate the heat inside the protective shell 14 to ensure the stability of the pressure-stabilizing pump 3. The protective shell 14 is in a stable operation state. The sound-absorbing plate 15 fixedly connected to the inner wall of the protective shell 14 can absorb noise. The water tank 1 is supported by a support seat to prevent the surface of the water tank 1 from contacting the ground, which may cause corrosion. After the water tank 1 has been used for a period of time, the inside of the water tank 1 needs to be cleaned. The driving motor 4 is started, and the driving motor 4 drives the threaded rod 501 to rotate. The threaded rod 501 drives the pulley 502 to rotate. The pulley 502 drives another pulley 502 to rotate through the belt, so that the two threaded rods 501 rotate synchronously. The surfaces of the two threaded rods 501 are threadedly sleeved with moving rods 503. The two moving rods 503 make the moving box 6 move stably under the action of the two threaded rods 501. At the same time, the output shaft of the waterproof motor 7 drives the cross rod 801 to rotate. The waterproof motor 7 adopts a double output shaft motor. When the mobile box 6 drives the waterproof motor 7 to move, the cross rod 801 rotates around the central axis of the output shaft under the action of the waterproof motor 7, so that the cleaning brush 802 can clean the inner wall of the water storage tank 1 and brush off the stains. The limit spring 9 can make the cleaning brush 802 always contact with the inner wall of the water storage tank 1 through the connecting piece 803, and the limit spring 9 makes the connection between the cleaning brush 802 and the water storage tank 1 have a certain elasticity, which can avoid hard contact and cause damage to the inner wall of the water storage tank 1. When the cross rod 801 rotates, it will drive the cleaning plate 12 to rotate through the T-shaped rod 11. When the cleaning plate 12 contacts the inner wall of the water storage tank 1, the mobile box 6 continues to move, and the cleaning plate 12 can clean the inner wall of the water storage tank 1. The left and right sides of the wall are cleaned, and the buffer spring 10 can play a buffering effect, so that the cleaning plate 12 can always contact the inner wall of the water tank 1. At this time, the buffer spring 10 is stretched, and the pressure sensor 13 on the cleaning plate 12 contacts the output shaft of the waterproof motor 7. The control system can detect the pressure value of the pressure sensor 13. After the pressure value is detected, the drive motor 4 is reversed, and the mobile box 6 drives the waterproof motor 7 to move in the opposite direction through the transmission mechanism 5, so as to achieve the reciprocating motion of the cleaning component 8 inside the water tank 1. The waterproof bearing 19 can support the output shaft of the waterproof motor 7, and also play a waterproof effect, preventing the water inside the water tank 1 from entering the inside of the mobile box 6, and the sewage generated by cleaning is discharged through the sewage outlet.
