Description

Technical Field

[0001] This invention relates to a water supply device, and more particularly to an intelligent negative pressure-free water supply device with a self-cleaning function. Background Technology

[0002] Currently, in order to avoid the problem of insufficient water supply pressure in cities due to the inability of water plants to increase the outlet pressure, people use negative pressure water supply equipment for water supply.

[0003] According to a novel multifunctional intelligent negative pressure-free water supply device with patent publication number CN215367517U, the device includes a flow stabilizing tank, a liquid level detector connected to the bottom of the flow stabilizing tank, support columns connected to both sides of the liquid level detector, a vacuum eliminator connected to one side of the upper end of the flow stabilizing tank, a fixed plate connected to the lower end of the support column, an anti-slip pad connected to the lower end of the fixed plate, a reinforcing protrusion connected to the lower end of the anti-slip pad, a protective shell connected to the outside of the first water pump and the second water pump, and a frequency converter connected to one end of the protective shell.

[0004] Although the aforementioned patent can detect the pressure inside the water pipe by setting a remote pressure gauge, and transmit the signal to the frequency converter when the pressure is low, the frequency converter controls the water pump to deliver water and ensure the outflow of water, the aforementioned patent does not have a cleaning mechanism. It is difficult to guarantee the quality of water during long-term use, and impurities are likely to accumulate inside the flow stabilizing tank after long-term use, which makes it impossible to effectively guarantee the quality of the water supplied by the aforementioned water supply equipment.

[0005] In order to solve the problems existing in the above-mentioned technologies, it is necessary to design an intelligent negative pressure-free water supply device with a self-cleaning function that can remove impurities, thereby achieving the effect of cleaning up attached impurities and impurities in the water. Summary of the Invention

[0006] In order to overcome the shortcomings of current water supply equipment that cannot remove impurities, which makes it difficult to guarantee water quality, the technical problem to be solved is to provide an intelligent negative pressure-free water supply equipment with a self-cleaning function that can remove impurities.

[0020] The propeller is rotatably connected to the fixed frame. The left side of the propeller is connected to the output shaft of the motor, and the propeller is rotatably connected to the flow regulator to agitate the water. When the motor is started, the output shaft of the motor drives the propeller to rotate, causing the water inside the flow regulator to move to the right and be filtered by the filter screen and filter cotton.

[0021] As a preferred embodiment of the present invention, the striking mechanism includes:

[0022] The first gear is connected to the output shaft of the motor and is located on the left side of the current regulator;

[0024] The push rod is connected to the eccentric position on the left side of the second gear;

[0025] The fixing blocks are symmetrically fixed to the front side of the current regulator;

[0026] The striking frame is rotatably connected between two fixed blocks. The striking frame contacts the outer side wall of the front of the current regulator and is used to strike the current regulator.

[0027] The contact block is fixed to the left side of the striking frame. When the second gear rotates, it intermittently squeezes the contact block by rotating the push rod, causing the striking frame to intermittently strike the outer wall of the flow regulator.

[0028] A torsion spring is connected between the striking frame and the two fixed blocks. The torsion spring is used to drive the striking frame to reset.

[0029] As a preferred embodiment of the present invention, it further includes a scraping mechanism, which comprises:

[0043] As a preferred embodiment of the present invention, it further includes:

[0044] The handle is attached to the top of the mounting bracket.

[0045] The present invention has the following beneficial effects: 1. By using a motor as the driving force, the striking frame can repeatedly strike the flow regulator, and the water in the flow regulator can continuously move to the right through the filter screen and filter cotton. Under the action of the filter screen and filter cotton, impurities in the water will be intercepted between the filter screen and filter cotton, and the striking frame can knock off the impurities attached inside the flow regulator, thereby filtering the water, ensuring the quality of the water, and removing impurities inside the flow regulator.

[0046] 2. After the tapping frame rotates forward and downward, the two external threaded tubes rotate and drive the two scraper rings to move closer to each other through the magnetic suction frame.

Detailed Implementation

[0062] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0063] Example 1

[0064] Please see the following: A smart, pressure-free water supply system with self-cleaning capabilities. Figure 1-5 The device includes a base 1, a flow regulator 2, a connecting pipe 3, a water outlet assembly 4, a mounting bracket 5, a filter screen 7, a filter cotton 8, a drive mechanism 9, and a striking mechanism 10. The flow regulator 2 is installed on the top rear side of the base 1, and the connecting pipe 3 is connected to the lower side of the flow regulator 2. The water outlet assembly 4 is installed on the top of the base 1 and is located in front of the flow regulator 2. The flow regulator 2 is connected to the front side of the connecting pipe 3. The mounting bracket 5 is slidably connected to the right side of the flow regulator 2. The mounting bracket 5 is made of rubber. The filter screen 7 is connected to the left side of the inner side of the mounting bracket 5, and the filter cotton 8 is connected to the right side of the inner side of the mounting bracket 5. Both the filter screen 7 and the filter cotton 8 are located inside the flow regulator 2. The drive mechanism 9 is located on the left side of the flow regulator 2, and the striking mechanism 10 is located on the front side of the flow regulator 2.

[0065] Please check Figure 3 It also includes a handle 6, which is connected to the top of the mounting bracket 5, making it convenient for workers to pull the mounting bracket 5 upwards.

[0066] Please check Figure 1 and Figure 3 The drive mechanism 9 includes a motor 91, a fixed frame 92, and a propeller 93. The motor 91 is mounted on the left side of the flow regulator 2. The output shaft of the motor 91 is rotatably connected to the left side of the flow regulator 2. The fixed frame 92 is welded to the left side inside the flow regulator 2. The propeller 93 is rotatably connected to the fixed frame 92. The left side of the propeller 93 is connected to the output shaft of the motor 91, and the propeller 93 is rotatably connected to the flow regulator 2.

[0067] Please check Figure 1 and Figure 5 The striking mechanism 10 includes a first gear 101, a second gear 1011, a push rod 102, a fixing block 103, a striking frame 104, a contact block 105, and a torsion spring 106. The first gear 101 is connected to the output shaft of the motor 91. The first gear 101 is located on the left side of the current regulator 2. The second gear 1011 is rotatably connected to the upper left front side of the current regulator 2. The first gear 101 and the second gear 1011 mesh. A push rod 102 is connected to the eccentric position on the left side of the flow regulator 2. Fixing blocks 103 are symmetrically welded to the front side of the flow regulator 2. A striking frame 104 is rotatably connected between the two fixing blocks 103. The striking frame 104 contacts the outer side wall of the front of the flow regulator 2. A contact block 105 is welded to the left side of the striking frame 104. Torsion springs 106 are connected between the striking frame 104 and the two fixing blocks 103. Both torsion springs 106 are sleeved on the striking frame 104.

[0068] When using this equipment for water supply, once there is water inside the flow regulator 2, the operator turns on the motor 91. The output shaft of the motor 91 drives the propeller 93 to rotate. Under the action of the propeller 93, the water inside the flow regulator 2 continuously moves to the right, passing through the filter screen 7 and filter cotton 8. Under the action of the filter screen 7 and filter cotton 8, impurities in the water are intercepted between the filter screen 7 and filter cotton 8, thereby achieving the effect of concentrating and filtering impurities in the water. At the same time, during the rotation of the output shaft of the motor 91, the first gear 101 drives the second gear 1011 to rotate, and the second gear 1011 drives the push rod 102 to rotate. During the rotation of the push rod 102, the push rod 102 contacts the contact block 105 and passes through... The contact block 105 pushes the striking frame 104 forward and downward, causing it to rotate forward and downward. The torsion spring 106 deforms, and then, as the push rod 102 continues to rotate, it disengages from the contact block 105. This causes the torsion spring 106 to reset, driving the striking frame 104 and contact block 105 to rotate in the opposite direction and reset. After resetting, the striking frame 104 strikes the flow regulator 2. Subsequently, under the continuous rotation of the push rod 102, the striking frame 104 repeatedly strikes the flow regulator 2. Thus, under the action of the striking frame 104 striking the flow regulator 2, impurities attached to the flow regulator 2 that cannot be washed away by the water flow are knocked down into the water. Then, the water continues to flow to the right... When the water is used, the knocked-off impurities are carried to the right by the water flow to the space between the filter screen 7 and the filter cotton 8. This process filters the water, ensuring its quality and simultaneously cleaning the inside of the flow regulator 2. When cleaning the water in the flow regulator 2 is no longer needed, simply turn off the motor 91. Afterward, the operator can use the device to send water from the flow regulator 2 into the connecting pipe 3, and finally supply the water from the connecting pipe 3 through the water outlet assembly 4. To clean the next batch of water, repeat the above steps. When it is necessary to clean the impurities trapped between the filter screen 7 and the filter cotton 8, the operator uses the handle 6 to lift the mounting bracket 5, filter screen 7, and filter cotton 8 upwards. Because the mounting bracket 5 is made of rubber... Therefore, after the mounting frame 5 moves upward, it will be squeezed and deformed by the flow regulator 2. At the same time, the filter screen 7 and filter cotton 8 will also deform. After the mounting frame 5 is pulled upward, the mounting frame 5, filter screen 7 and filter cotton 8 will spring back to their original positions. Then, the staff can clean the impurities between the filter screen 7 and filter cotton 8. After cleaning, the mounting frame 5 is placed back down on the flow regulator 2. The mounting frame 5 moves the filter screen 7 and filter cotton 8 together. After the mounting frame 5 moves downward, it will be squeezed and deformed by the flow regulator 2. At the same time, the filter screen 7 and filter cotton 8 will also deform. After the mounting frame 5 is installed back down on the flow regulator 2, the mounting frame 5, filter screen 7 and filter cotton 8 will spring back to their original positions. The equipment can be used by following the above operations.

[0069] Example 2

[0070] Based on Example 1, please refer to Figure 1 , Figure 6 The diagram also includes a scraping mechanism 11, which includes an externally threaded tube 111, a magnetic frame 112, and a scraper ring 113. The externally threaded tube 111 is symmetrically connected to the striking frame 104. The two externally threaded tubes 111 are threadedly connected to the magnetic frame 112 on the opposite sides. Both magnetic frames 112 are in contact with the flow regulator 2. The inner sidewall of the flow regulator 2 is symmetrically slidably connected to the scraper ring 113. Both scraper rings 113 are located between the propeller 93 and the filter screen 7, and the two scraper rings 113 are magnetically attracted to the adjacent magnetic frame 112.

[0071] When the striking frame 104 rotates forward and downward, it drives the two externally threaded tubes 111 on it to rotate. Under the action of the threaded engagement between the magnetic suction frame 112 and the externally threaded tubes 111, the rotation of the two externally threaded tubes 111 drives the two magnetic suction frames 112 to move closer to each other. The two magnetic suction frames 112 then drive the two scraper rings 113 to move closer to each other through magnetic attraction. The two scraper rings 113 then scrape off the impurities attached to the flow regulator 2. Afterwards, when the striking frame 104 rotates in the opposite direction... Then, the striking frame 104 will drive the two external threaded tubes 111 on it to rotate in opposite directions. After the two external threaded tubes 111 rotate in opposite directions, they will drive the two magnetic suction frames 112 to move away from each other. The two magnetic suction frames 112 will then drive the two scraper rings 113 away from each other through magnetic attraction. In this way, while the striking frame 104 strikes the flow regulator 2, the two scraper rings 113 can scrape off the impurities inside the flow regulator 2 that cannot be knocked off, thereby completely cleaning the dirt attached to the flow regulator 2.

[0072] Example 3

[0073] Based on Example 2, please refer to Figure 1 , Figure 8 and Figure 9 It also includes a stabilizing mechanism 12, which includes a sliding frame 121, a compression spring 122, and a limiting rod 123. The sliding frame 121 is slidably connected to the right side of the flow regulator 2. The sliding frame 121 slides through the right side of the flow regulator 2 and is located on the right side of the filter cotton 8. A compression spring 122 is connected between the sliding frame 121 and the right side of the inner wall of the flow regulator 2. The compression spring 122 is sleeved on the sliding frame 121. The limiting rod 123 is symmetrically welded to the front and back of the right side of the sliding frame 121.

[0074] When the water in the flow regulator 2 moves to the right due to the propeller 93, the water pressure of the water moving to the right will push the sliding frame 121 to the right, compressing the compression spring 122. After the sliding frame 121 moves to the right, it will drive the two limit rods 123 to move to the right and hold the top of the mounting frame 5 against it. This can prevent the mounting frame 5, filter screen 7 and filter cotton 8 from being displaced arbitrarily due to water pressure when cleaning the inside of the flow regulator 2 and the water, so that impurities in the water cannot be intercepted between the filter screen 7 and the filter cotton 8. This allows the filtration operation to proceed normally. When the propeller 93 stops rotating and stops cleaning the water, the compression spring 122 resets and drives the sliding frame 121 and the two limit rods 123 to move to the left to reset. After the two limit rods 123 move to the left, they no longer hold the mounting frame 5 against it.

[0075] Example 4

[0076] Based on Example 3, please see Figure 5 , Figure 10 and Figure 11 It also includes a filter mechanism 13, which includes a first filter element 131 and a second filter element 132. The first filter element 131 is installed on the front side of the inside of the connecting pipe 3, and the second filter element 132 is installed on the front side of the first filter element 131.

[0077] When water enters the connecting pipe 3, it passes through the first filter element 131 and the second filter element 132. Under the action of the first filter element 131 and the second filter element 132, the first filter element 131 will filter out the tiny impurities in the water, and the second filter element 132 will filter the water again, making the water cleaner and more thorough, thus further ensuring the quality of the water.

[0078] Example 5

[0079] Based on Example 4, please see Figure 12 and Figure 13 It also includes a protective mechanism 14, which includes a fixed frame 141 and a protective net 142. The fixed frame 141 is bolted to the left side inside the flow regulator 2, and the protective net 142 is connected to the inner side of the fixed frame 141. The protective net 142 is located between the left scraper ring 113 and the propeller 93.

[0080] When water enters the flow regulator 2, the protective net 142 will intercept impurities in the water on the right side of the protective net 142. In the subsequent water cleaning process, the protective net 142 can continue to intercept impurities in the water on the right side of the protective net 142, thereby preventing impurities from getting tangled or attached to the propeller 93, and avoiding the propeller 93 from being unable to rotate normally due to impurities.

[0081] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
