Description

Technical Field

[0001] This invention relates to a water pressure boosting device, and more particularly to a booster pump. Background Technology

[0002] A booster pump is a pump used to increase pressure. It is most commonly used to pressurize water in pipes, thereby increasing the flow rate and the flow rate per unit time. It can effectively solve the problem of insufficient water pressure. Specifically, it can be used for boosting water pressure in water heaters, saunas, solar water heaters, and reverse osmosis water purifiers.

[0003] In practical applications, existing DC booster pumps require the addition of a controller electrically connected to the pump. The controller controls the pump's operating status, switching between operating modes (manual or automatic) and gear selection (motor power, etc.). Currently, the controller and pump unit are integrated into a single unit via a housing and cannot be separated. Relevant patent documents can be found in Chinese Utility Model Patent No. ZL201922482540.9, "Shielded Centrifugal Booster Pump" (authorization announcement number CN211449093U); and Chinese Utility Model Patent No. ZL 202121328750.3, "A Booster Pump" (authorization announcement number CN215486636U).

[0004] Booster pumps are often installed in locations with many pipes and other components. In some small or irregular spaces, the installation of a booster pump can be inconvenient for operation and inspection, causing great inconvenience. Therefore, improvements are needed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a booster pump in which the control display module can rotate relative to the pump body to facilitate operation or viewing, in view of the above-mentioned technical status.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a booster pump, comprising a pump body and a control display module disposed on the pump body, wherein the pump body has an inlet port and an outlet port, and the control display module is used to control the working status of the booster pump and display the working status; characterized in that the pump body has a first mounting end face and a second mounting end face, and the plane on which the first mounting end face is located intersects with the plane on which the second mounting end face is located, and the control display module is detachably disposed on the first mounting end face and the second mounting end face and maintains an electrical connection with the pump body;

[0007] The control and display module includes

[0008] The outer casing has a display area formed on its front surface.

[0009] The drive board is located inside the aforementioned housing.

[0010] A movable terminal block is disposed inside the aforementioned housing and electrically connected to the drive board. The lower end face of the aforementioned movable terminal block has a plurality of annularly spaced movable conductive sheets.

[0011] The first rotating seat is ring-shaped and located on the port of the aforementioned housing, limiting the position of the moving wiring plate;

[0012] The second rotating seat is ring-shaped and located on the port of the aforementioned housing and at the lower end of the second rotating seat;

[0013] The base is located on the inner ring of the aforementioned first rotating seat and second rotating seat, and the aforementioned first rotating seat and second rotating seat can rotate relative to the base;

[0014] A fixed terminal block is disposed on the upper surface of the aforementioned base, and the upper surface of the fixed terminal block has a fixed conductive plate that is in contact with and conducts electricity to the corresponding moving conductive plate; and

[0015] The plug-in connector is located on the outer end face of the aforementioned second rotating seat and can be detached from and connected to the pump body.

[0016] Of course, a third mounting end face can also be added. At the same time, the first and second mounting end faces can be set separately as front, back, top, bottom, left, and right.

[0017] The preferred design for the rotational engagement is as follows: a plurality of first balls are movably disposed on the lower end face of the first rotating seat near the inner ring; a plurality of second balls are movably disposed on the upper end face of the second rotating seat near the inner ring; a convex ring extends radially outward from the base, the convex ring being located between the lower end face of the first rotating seat and the upper end face of the second rotating seat, the upper end face of the aforementioned convex ring having a first annular groove for the first balls to roll back and forth, and the lower end face having a second annular groove for the aforementioned second balls to roll back and forth.

[0018] The lower end face of the second rotating seat is formed with a toothed ring. Correspondingly, the plug-in seat has a spring piece that cooperates with the aforementioned toothed ring to generate damping and limiting. There is a damping sensation and a stop sensation during the rotation of the outer shell.

[0019] The preferred electrical connection structure is as follows: both the first and second mounting faces have conductive pins, and the lower face of the fixed terminal block has a socket that conductively engages with the aforementioned conductive pins.

[0020] To protect the spare mounting surface, the following improvements are made: the first mounting end face or the second mounting end face is detachably provided with a cover that can cover the conductive pins.

[0021] To improve sealing and waterproofing, a recessed area is formed on the inner side of the first mounting end face, and the conductive pin is located in the recessed area. A sealing ring is provided on the outer periphery of the recessed area.

[0022] Preferably, the socket includes a base and two resilient locking feet extending outward from the base and close to each other, forming a slot between the resilient locking feet. When the conductive pin is inserted into the socket, the conductive pin is inserted into the slot (and remains in contact with the resilient locking feet).

[0023] To improve strength, reinforcing ribs are integrally formed on both sides of the conductive pin.

[0024] The preferred connection method between the plug-in connector and the pump body is as follows: the pump body has spaced-apart connection holes, and correspondingly, both ends of the plug-in connector have downwardly extending elastic buckles that can fit into the connection holes. Furthermore, the elastic buckles have a button portion that, when pressed, can release the locking of the elastic buckles onto the connection holes.

[0025] Compared with existing technologies, the advantages of this invention are: It adds a spare mounting surface, allowing the control display module to select a suitable mounting surface based on the actual installation environment, ease of operation, and ease of viewing, thus greatly benefiting the user. The control display module can rotate relative to the pump body, allowing for angle adjustment in confined spaces based on the actual viewing angle, facilitating the monitoring of control operations and working status.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] like Figure 1 and Figure 2As shown, the booster pump in this embodiment includes a pump body 2, a control and display module 1 and a cover 7 disposed on the pump body 2. The pump body 2 has a water inlet port 21 and a water outlet port 22. The control and display module 1 is used to control the working status of the booster pump and display the working status. The control and display module 1 in this embodiment is equivalent to a human-machine interface, with a built-in circuit board, which can display the working mode and gear. Operations such as manual or automatic working mode, gear switching, and motor power can be completed on it. Specifically, it can be equipped with a touch screen or a digital display screen.

[0036] The pump body 2 has a first mounting end face 24 at the top and a second mounting end face 26 on the side. The plane where the first mounting end face 24 is located intersects the plane where the second mounting end face 26 is located. The control display module 1 and the cover are detachably mounted on the first mounting end face 24 and the second mounting end face 26 and are electrically connected to the pump body 2.

[0037] like Figure 3 , Figure 4 and Figure 5 As shown, the control display module 1 in this embodiment includes a housing 11, a drive board 12, a moving connector 13, a first rotating seat 14, a second rotating seat 16, a base 15, a fixed connector 18, and a plug-in connector 17.

[0038] The front end face of the housing 11 forms a display area 111. The drive plate 12 is disposed inside the housing 11. The movable connector 13 is disposed inside the housing 11 and electrically connected to the drive plate 12. The lower end face of the movable connector 13 has a plurality of annularly spaced movable conductive sheets 131. The first rotating seat 14 is annular and disposed on the port of the housing 11 and limits the movable connector 13. The lower end face of the first rotating seat 14 is provided with a plurality of first balls 31 near the inner ring. The second rotating seat 16 is annular and disposed on the port of the housing 11 and located at the lower end of the second rotating seat 16. The upper end face of the second rotating seat 16 is provided with a plurality of second balls 32 near the inner ring. The lower end face of the second rotating seat 16 is formed with a toothed ring 161.

[0039] The base 15 is located on the inner ring of the first rotating seat 14 and the second rotating seat 16. The first rotating seat 14 and the second rotating seat 16 can rotate relative to the base 15. The base 15 has a convex ring 151 extending radially outward. The convex ring 151 is located between the lower end face of the first rotating seat 14 and the upper end face of the second rotating seat 16. The upper end face of the convex ring 151 has a first annular groove 152 for the first ball 31 to roll back and forth, and the lower end face has a second annular groove 153 for the second ball 32 to roll back and forth.

[0040] A fixed terminal block 18 is disposed on the upper end face of the base 15. The upper end face of the fixed terminal block 18 has a fixed conductive piece 181 that is in contact with and conducts electricity to the corresponding moving conductive piece 131. The lower end face of the fixed terminal block 18 has a socket 5.

[0041] The plug-in connector 17 is located on the outer end face of the second rotating seat 16 and can be detached from the pump body 2. The plug-in connector 17 has a spring piece 173 that cooperates with the gear ring 161 to generate damping and limiting.

[0042] Combination Figure 2 As shown, the inner side of the first mounting end face 24 is recessed to form a recessed area, and the conductive pin 4 is disposed in the recessed area. A sealing ring 25 is provided on the outer periphery of the recessed area. The inner side of the second mounting end face 26 is recessed to form a recessed area, and the conductive pin 4 is disposed in the recessed area. A sealing ring 27 is provided on the outer periphery of the recessed area. The conductive pin 4 is conductively engaged with the socket 5.

[0043] like Figure 6 As shown, the socket 5 in this embodiment includes a base 51 and two elastic locking feet 52 extending outward from the base 51 and close to each other. A slot 53 is formed between the elastic locking feet 52. When the conductive plug 4 is inserted into the socket 5, the conductive plug 4 is inserted into the slot 53 and keeps in contact with the elastic locking feet 52.

[0044] Figure 7 As shown, the conductive pin 4 has reinforcing ribs 41 integrally formed on both sides.

[0045] Combination Figure 2 and Figure 3 As shown, the pump body 2 has spaced-apart connection holes 23. Correspondingly, the plug-in base 17 has elastic latches 171 extending downward at both ends to fit into the connection holes 23. The elastic latches 171 have a button portion 172 that can release the locking of the elastic latches 171 onto the connection holes 23 when pressed. The detachable connection method of the cover 7 is referenced from the setting of the control display module.

[0046] like Figure 1 As shown, when the pump body is suitable for mounting the control and display module on the first mounting surface, the control and display module is placed on the first mounting surface, the elastic buckle is inserted into the corresponding connection hole, and the conductive pins are in contact with the slot to conduct electricity; at the same time, the cover is placed on the second mounting surface. The second mounting surface is then used as a spare.

[0047] like Figure 8 As shown, when the pump body is suitable for mounting the control display module on the second mounting end face, press the button part, the elastic buckle releases the lock on the connection hole, the control display module is taken out upward, and the cover is removed at the same time. The control display module is placed on the second mounting end face, and the cover is placed on the first mounting end face.

[0048] An additional spare mounting surface has been added, allowing the control and display module to select the appropriate mounting surface based on the actual installation environment, ease of operation, and ease of viewing, thus greatly benefiting the user.

[0049] When the viewing angle of the control display module needs to be adjusted, simply drive the second rotating seat to rotate the outer shell relative to the pump body. It can rotate freely through the sliding cooperation of the second ball bearing and the corresponding fixed ball bearing. At the same time, the moving conductive plate and the corresponding fixed conductive plate always maintain contact and conduction. During the rotation, there is a damping stop between the spring and the toothed ring, which provides a good operating feel and can also quickly position the device.

[0050] The control display module is separate from the pump body and can be detached. This allows a single pump body to be equipped with multiple control display modules of different specifications, which is beneficial for product diversification; it also helps reduce the manufacturing cost of the pump body and achieve large-scale production; when products are upgraded, only the control display module needs to be replaced, thereby reducing the cost of upgrading; and maintenance is more convenient.

[0051] Of course, in this embodiment, the socket can also be placed on the first mounting end face and the second mounting end face, while the conductive pins can be placed on the control and display module. This will not be discussed further here.
