Technical Field
[0001] This utility model relates to the field of shower head technology, specifically a pressure-boosting shower head. Background Technology
[0002] In today's bathroom fixtures industry, showerheads, as key everyday appliances, have seen significant technological advancements. As people's living standards improve, their performance requirements for showerheads are becoming increasingly stringent, especially regarding water pressure. Among the many types of showerheads, pressure-boosting showerheads have emerged as a popular choice for solving water pressure issues.
[0003] In places like hotels, larger diameter water pipes are often used to achieve sufficient pressure and flow. However, for most homes that have already been renovated, the size of the plumbing is fixed and difficult to change. In such cases, to obtain higher water pressure, the flow rate must be reduced. For some users, insufficient flow can lead to longer shower times, resulting in a poor user experience and potentially less than ideal water-saving performance. Therefore, we offer a pressure-boosting showerhead. Utility Model Content
[0004] To solve the above-mentioned technical problems, this application provides a pressure-boosting shower head, including a handle, a sleeve fixedly connected to the top left side of the handle, a water passage fixedly opened inside the handle, a water inlet opened at the center of the left side of the water passage, an installation cylinder fixedly connected to the top left side of the water passage, a connecting port fixedly opened at the center of the bottom end of the installation cylinder, a limiting groove fixedly opened at the bottom end of the installation cylinder outside the connecting port, an external thread tooth fixedly connected to the inner wall of the installation cylinder, and an adjusting cylinder provided inside the installation cylinder.
[0005] In some embodiments, a circular groove is fixedly opened at the bottom of the inner side of the regulating cylinder, and a plurality of water outlet holes are fixedly opened on the inner wall of the circular groove in a circular and equidistant manner. A limiting ring is fixedly connected to the bottom of the regulating cylinder, a hand-tightening cap is fixedly connected to the top of the regulating cylinder, and internal thread teeth are fixedly opened on the outer side of the regulating cylinder.
[0006] In some embodiments, the adjusting cylinder is slidably connected to a limiting groove fixedly opened at the bottom of the mounting cylinder and located outside the communication port via a limiting ring provided at the bottom.
[0007] In some embodiments, the adjusting cylinder is connected to the external thread teeth fixedly disposed on the inner wall of the mounting cylinder by means of internal thread teeth opened on the outer side.
[0008] In some embodiments, the hand-tightening cap has several evenly distributed anti-slip grooves on its exterior, the hand-tightening cap is rotatably connected to the sleeve, and the circular slot is connected to the water passage through a connecting port.
[0009] In some embodiments, an external threaded interface is fixedly connected to the right side of the handle, a nozzle is fixedly connected to the left side of the handle, a water distribution plate is fixedly connected to the top inner side of the nozzle, an external threaded interface is fixedly connected to the outer side of the top of the water distribution plate, a sealing cap is provided on the top of the nozzle, an internal threaded interface is fixedly connected to the bottom of the sealing cap, a sealing plate is fixedly connected to the top of the sealing cap, and a plurality of evenly distributed water spray holes are fixedly opened on the end face of the sealing plate.
[0010] In some embodiments, the sealing cap is threadedly connected to the outer side of the top of the water distribution plate via an inner threaded interface at the bottom. A sealing ring is provided at the contact point between the inner threaded interface and the outer threaded interface, and the diameter of the spray hole is tapered with a smaller outer diameter and a larger inner diameter.
[0011] This utility model has at least the following beneficial effects: This invention utilizes a mounting cylinder, an adjusting cylinder, a water outlet, a water inlet, and a connecting port. The external threaded connector is connected to a water pipe nut. When the faucet is turned on, the water passage is filled with water. With the adjusting cylinder at its highest position, water flows through the water passage, through the connecting port, and then to the water inlet, directly entering the nozzle and causing water to spray out. If the user finds the water pressure insufficient, simply rotate the hand-tightening cap to rotate the adjusting cylinder. The adjusting cylinder moves downwards until it contacts the bottom of the mounting cylinder. At this point, the water inlet changes direction, flowing through the water passage, through the connecting port, through the circular slot, and finally through the water outlet into the water inlet before entering the nozzle. Internally, pressurization is achieved by increasing water flow resistance. According to the dynamic pressure formula, the lower the flow velocity, the higher the static pressure. Under the same cross-section, reducing the flow rate can increase the static pressure. By changing the cross-sectional area of the flow, reducing the cross-sectional area can increase the static pressure, and the dynamic pressure will also increase accordingly. However, this method obviously achieves pressurization under the premise of reducing the flow rate. Users will clearly feel that the water volume is insufficient, affecting the comfort of showering. However, by setting multiple water outlets, the cross-sectional area of the flow can be changed through multiple channels without reducing the water flow rate, thereby increasing the water pressure without changing the water flow size, reducing the shower time, and improving the experience.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Example 1: Please see Figure 1-4 This utility model provides a technical solution: a pressure-boosting shower head, including a handle 1, a sleeve 102 fixedly connected to the top left side of the handle 1, a water passage 103 fixedly opened inside the handle 1, a water inlet 107 opened at the center of the left side of the water passage 103, an installation cylinder 104 fixedly connected to the top left side of the water passage 103, a connecting port 108 fixedly opened at the center of the bottom end of the installation cylinder 104, a limiting groove 106 fixedly opened at the bottom end of the installation cylinder 104 and outside the connecting port 108, an external thread tooth 105 fixedly connected to the inner wall of the installation cylinder 104, and an adjusting cylinder 2 provided inside the installation cylinder 104. It can change the cross-sectional area of the flow through multiple channels without reducing the water flow rate, increase the static pressure, and increase the water pressure without changing the water flow size, thereby reducing the shower time and improving the experience.
[0016] A circular slot 201 is fixedly opened at the bottom of the inner side of the regulating cylinder 2. Several circularly distributed water outlet holes 202 are fixedly opened on the inner wall of the circular slot 201. A limiting ring 203 is fixedly connected to the bottom of the regulating cylinder 2, and a hand-tightening cap 204 is fixedly connected to the top of the regulating cylinder 2. An internal thread tooth 205 is fixedly opened on the outer side of the regulating cylinder 2. The regulating cylinder 2 is slidably connected to the limiting slot 106 fixedly opened at the bottom of the mounting cylinder 104 and located outside the communication port 108 through the limiting ring 203 at the bottom. The internal thread tooth 205 on the outer side of the regulating cylinder 2 is used to connect the regulating cylinder 2. The external thread 105 fixedly installed on the inner wall of the mounting cylinder 104 engages with the hand-tightening cap 204. The outside of the hand-tightening cap 204 has several evenly distributed anti-slip grooves. The hand-tightening cap 204 is rotatably connected to the sleeve 102, and the circular slot 201 is connected to the water passage 103 through the connecting port 108. Connect the external thread interface 101 to the water pipe nut, then turn on the faucet to fill the water passage 103 with water. At this time, when the adjusting cylinder 2 is at its highest position, water can directly enter through the water passage 103, the connecting port 108, and the inlet 107. Water is sprayed out into the nozzle 3. If the user feels the water pressure is insufficient, simply rotate the hand-tightening cap 204 to rotate the adjusting cylinder 2. The adjusting cylinder 2 moves downwards until it contacts the bottom of the mounting cylinder 104. At this point, the water inlet channel changes; water flows through the water passage 103, through the connecting port 108, then through the circular slot 201, and finally through the water outlet 202 into the inlet 107 before entering the nozzle 3. This increases the water flow resistance, thus boosting the pressure. According to the dynamic pressure formula, the lower the flow velocity, the higher the static pressure. Under the same cross-section, reducing the flow rate can increase the static pressure; by changing the cross-sectional area of the flow, reducing the cross-sectional area can increase the static pressure, and the dynamic pressure will also increase accordingly. However, this method obviously achieves pressure increase under the premise of reducing the flow rate. Users will clearly feel that the water volume is insufficient when using it, which affects the comfort of bathing. However, by setting multiple water outlets 202, the cross-sectional area of the flow can be changed in multiple channels without reducing the water flow rate, thereby increasing the static pressure. This achieves the goal of increasing water pressure without changing the water flow size, reducing the bathing time, and improving the experience.
[0017] Example 2: Please see Figure 5-6This utility model provides a technical solution: a pressure-boosting shower head, including a handle 1, a sleeve 102 fixedly connected to the top left side of the handle 1, a water passage 103 fixedly opened inside the handle 1, a water inlet 107 opened at the center of the left side of the water passage 103, an installation cylinder 104 fixedly connected to the top left side of the water passage 103, a connecting port 108 fixedly opened at the center of the bottom end of the installation cylinder 104, a limiting groove 106 fixedly opened at the bottom end of the installation cylinder 104 outside the connecting port 108, an external thread tooth 105 fixedly connected to the inner wall of the installation cylinder 104, an adjusting cylinder 2 provided inside the installation cylinder 104, a circular groove 201 fixedly opened at the bottom end of the inner side of the adjusting cylinder 2, and the inner wall of the circular groove 201... The upper part of the regulating cylinder 2 has several circularly equidistantly distributed water outlet holes 202. The bottom of the regulating cylinder 2 is fixedly connected to a limiting ring 203, and the top of the regulating cylinder 2 is fixedly connected to a hand-tightening cap 204. The outer side of the regulating cylinder 2 is fixedly provided with internal thread teeth 205. The regulating cylinder 2 is slidably connected to the limiting groove 106 fixedly opened at the bottom of the mounting cylinder 104 and located outside the connecting port 108 through the limiting ring 203 at the bottom. The regulating cylinder 2 is engaged with the external thread teeth 105 fixedly provided on the inner wall of the mounting cylinder 104 through the internal thread teeth 205 on the outer side. The hand-tightening cap 204 is provided with several evenly distributed anti-slip grooves on the outside. The hand-tightening cap 204 is rotatably connected to the sleeve 102, and the circular slot 201 is connected through the connecting port 102. The nozzle 108 is connected to the water passage 103. The external threaded connector 101 is connected to the water pipe nut. Then, the faucet is turned on, filling the water passage 103 with water. At this point, with the regulating cylinder 2 at its highest position, water flows through the water passage 103, through the connecting port 108, and then to the inlet 107, directly into the nozzle 3, causing water to spray out. If the user feels the water pressure is insufficient, simply rotate the hand-tightening cap 204 to rotate the regulating cylinder 2. The regulating cylinder 2 moves downwards until it contacts the bottom of the mounting cylinder 104. At this point, the water inlet changes, and water flows through the water passage 103, through the connecting port 108, through the circular slot 201, and finally through the outlet 202 into the inlet 107. In section 07, pressure is increased by increasing water flow resistance inside the nozzle 3. According to the dynamic pressure formula, the lower the flow velocity, the higher the static pressure. Under the same cross-section, reducing the flow rate can increase the static pressure. By changing the cross-sectional area of the flow, reducing the cross-sectional area can increase the static pressure, and the dynamic pressure will also increase accordingly. However, this method obviously achieves pressure increase under the premise of reducing the flow rate. When using it, users will clearly feel that the water volume is insufficient, which affects the comfort of showering. However, by setting multiple water outlets 202, the cross-sectional area of the flow can be changed in multiple channels without reducing the water flow rate, thereby increasing the water pressure without changing the water flow size, reducing the shower time, and improving the experience.

A sealing ring is provided at the contact point between the internal threaded interface 304 and the external threaded interface 302. The diameter of the water spray holes 306 is set in a conical shape with a smaller outer diameter and a larger inner diameter. By setting the diameter of the water spray holes 306 in a conical shape with a smaller outer diameter and a larger inner diameter, a certain water pressure can be formed, and the water output is faster.
[0019] Based on Embodiment 1, a sealing cap 303, a sealing plate 305, and a water spray hole 306 are added. Water entering the nozzle 3 is divided by the water distribution plate 301 and then evenly spread on the sealing plate 305. At this time, the water is sprayed out through the water spray hole 306 and acts on the human body. By setting the diameter of the water spray hole 306 into a cone shape with a smaller outer diameter and a larger inner diameter, a certain water pressure can be formed, the water output is faster, and the user experience is further improved.
