Description

Technical Field

[0001] This utility model relates to the field of shower head technology, specifically to a shower head with a replaceable filter core. Background Technology

[0002] A shower head, also known as a water sprayer, was originally a device for watering flowers, potted plants, and other plants. Later, it was modified into a shower device, making it a common bathroom item. A shower head is a device used for showering, also called a shower nozzle or shower head. It is a device connected to a water pipe that can produce a jet of water for people to bathe and rinse their bodies. In daily life, a shower head with a replaceable filter cartridge is often needed.

[0003] Existing showerhead technology can only effectively disassemble and install the filter cartridge, but cannot effectively disassemble the front cover. When using a showerhead, a filter cartridge is generally required to prevent clogging inside the nozzle. The filter cartridge filters the water to reduce the probability of clogging. However, after prolonged use, scale and other impurities inevitably accumulate inside the nozzle and front cover. Since existing showerhead technology cannot effectively disassemble the front cover, scale buildup over time affects water quality and the spray effect, and may even cause nozzle clogging, reducing the overall practicality of the showerhead. Although some showerheads do have removable front covers, these are usually disassembled using bolts, which is not only time-consuming and laborious, but also increases the burden on the user.

[0004] Comparing this to Chinese patent publication number CN221288280U, this utility model relates to the field of showerhead technology, and more particularly to a showerhead with a replaceable filter cartridge, including a nozzle and an installation mechanism. The filter cartridge is installed inside the connecting pipe, and the installation mechanism is also provided inside the connecting pipe. With this showerhead featuring a replaceable filter cartridge, the installation mechanism allows for easy installation of the filter cartridge inside the connecting pipe. First, a wrench is turned, causing a limiting post to slide into a movable groove. When the limiting post is fully engaged in the movable groove, the filter cartridge is placed inside the connecting pipe, aligning the limiting groove with the movable groove. Then, the force applied to the wrench is released, causing a return spring to spring back, returning the limiting post to its original position. At this point, one end of the limiting post is engaged in the limiting groove, thus the limiting block and the limiting post fix the filter cartridge inside the connecting pipe.

[0005] The above solution allows for easy disassembly and assembly of the filter element, but it still cannot effectively disassemble the front cover, thus failing to effectively clean the interior of the front cover and the nozzle, and thus failing to solve the problems mentioned in the background art.

[0006] Therefore, those skilled in the art provide a shower head with a replaceable filter cartridge to solve the problems mentioned in the background art. Utility Model Content

[0008] The nozzle is connected to the liquid outlet end of the connecting pipe, and a fixing frame is symmetrically provided on the outside of the nozzle;

[0009] A front cover is disposed inside the nozzle, and L-shaped plates are symmetrically arranged on the outside of the front cover. Mounting plates are fixedly connected to the outside of both L-shaped plates.

[0010] The mounting components are located inside the mounting plate and are used to fix the mounting plate to the fixing frame, thereby enabling the front cover and the nozzle to be disassembled and assembled.

[0011] The filter element body is disposed inside the connecting pipe. The upper surface of the filter element body is symmetrically provided with abutment blocks, and the inner wall of the connecting pipe is symmetrically provided with limiting frames. The interior of each of the two limiting frames is provided with a guide groove for the abutment blocks to move.

[0012] A fixing component is disposed outside the connecting pipe and is used to fix the limiting frame and the abutment block, thereby enabling the filter element body to be disassembled and assembled.

[0013] As a further improvement to this technical solution, the mounting assembly includes an inner plate fixedly connected inside the mounting plate. Telescopic rods are fixedly connected to the upper and lower surfaces of the inner plate. Insert rods are fixedly connected to the telescopic ends of the multiple telescopic rods. Return springs are sleeved on the outside of the multiple telescopic rods. The multiple return springs abut against the insert rods and the inner plate. Guide grooves for the insertion rods to move are opened on the upper and lower surfaces of the mounting plate and the fixing frame.

[0014] As a further improvement to this technical solution, a rubber sealing ring is bonded to the outside of the front cover.

[0015] As a further improvement to this technical solution, the fixing assembly includes a fixing plate fixedly connected to the outside of the connecting pipe. A sliding rod is fixedly connected inside the fixing plate. A movable plate is provided inside the fixing plate. A guide groove for the sliding rod to move is opened inside the movable plate. An anti-spring is sleeved on the outside of the sliding rod. The anti-spring abuts against the movable plate and the fixing plate. Connecting rods are symmetrically arranged on the front end surface of the movable plate. Pull plates are fixedly connected to the other ends of the two connecting rods.

[0016] As a further improvement to this technical solution, the connecting pipe is fitted with an anti-slip sleeve, and the anti-slip sleeve has herringbone anti-slip grooves evenly spaced on its outer side.

[0017] As a further improvement to this technical solution, the connecting pipe is provided with external threads.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In this shower head with a replaceable filter cartridge, the filter cartridge body is fixedly installed by means of an installation and fixing component. Simply insert the filter cartridge body into the connecting pipe, and the filter cartridge body will move the contact blocks synchronously. When both contact blocks are inserted into the limiting frame, the fixing component secures the limiting frame to the contact blocks, thus fixing the filter cartridge body in place. This allows the filter cartridge body to effectively filter water. When the front cover needs to be removed for easy cleaning of the front cover and the inside of the spray head, the installation component allows for easy removal of the installation plate from the fixing frame. This facilitates replacement of the front cover or cleaning of the inside of the front cover and the spray head, effectively improving water quality and spray effect, enhancing the overall practicality of the shower head, and saving time and effort.

[0027] 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.

[0028] Please see Figure 1 - Figure 5 As shown, this embodiment provides a shower head with a replaceable filter cartridge, including a connecting pipe 1, and further including:

[0029] The nozzle 2 is connected to the liquid outlet end of the connecting pipe 1, and the nozzle 2 is symmetrically provided with a fixing frame 9 on the outside;

[0030] The front cover 3 is located inside the nozzle 2. The front cover 3 is symmetrically provided with L-shaped plates 7 on its outside. Mounting plates 8 are fixedly connected to the outside of both L-shaped plates 7.

[0031] The mounting components are located inside the mounting plate 8 and are used to fix the mounting plate 8 to the fixing frame 9, thereby enabling the front cover 3 and the nozzle 2 to be disassembled and assembled.

[0032] The filter element body 10 is disposed inside the connecting pipe 1. The upper surface of the filter element body 10 is symmetrically provided with abutment blocks 16, and the inner wall of the connecting pipe 1 is symmetrically provided with limiting frames 17. The interior of the two limiting frames 17 is provided with guide grooves for the abutment blocks 16 to move.

[0033] A fixing component is disposed outside the connecting pipe 1 and is used to fix the limiting frame 17 and the abutment block 16, thereby enabling the filter element body 10 to be disassembled and assembled.

[0034] The working principle described above is as follows: When the filter body 10 needs to be fixedly installed, simply insert the filter body 10 into the connecting pipe 1. At this time, the filter body 10 will drive the contact block 16 to move synchronously. When both contact blocks 16 are inserted into the limiting frame 17, the limiting frame 17 and the contact block 16 are fixed by the fixing component. At this time, the filter body 10 can be fixedly installed, so that the filter body 10 can effectively filter water. When the front cover 3 needs to be disassembled to facilitate the cleaning of the front cover 3 and the inside of the spray head 2, simply use the installation component to easily disassemble the mounting plate 8 and the fixing frame 9. At this time, the front cover 3 can be disassembled, making it convenient for the user to replace the front cover 3 or clean the inside of the front cover 3 and the spray head 2. This can effectively improve the water quality and the water spray effect, enhance the overall practicality of the shower head, and save time and effort.

[0035] To effectively secure the front cover 3 to the nozzle 2, the mounting assembly includes an inner plate 18 fixedly connected inside the mounting plate 8. Telescopic rods 19 are fixedly connected to both the upper and lower surfaces of the inner plate 18. Insert rods 20 are fixedly connected to the telescopic ends of the telescopic rods 19. Return springs 21 are fitted around the outside of each telescopic rod 19, and these return springs 21 abut against the insert rods 20 and the inner plate 18. Guide grooves for the movement of the insert rods 20 are provided on the upper and lower surfaces of the mounting plate 8 and the fixing frame 9. When securing the front cover 3 to the nozzle 2, simply press the insert rods 20; at this time, the insert rods 20 will engage the telescopic rods 19 and the return rods 20. Spring 21 compresses synchronously, and then the mounting plate 8 is inserted into the interior of the fixed frame 9. At this time, the mounting plate 8 will drive the insertion rod 20 to move synchronously. When the mounting plate 8 drives the insertion rod 20 to move into the guide grooves on the upper and lower surfaces of the fixed frame 9, the reset spring 21 resets and drives the insertion rod 20 to move synchronously. When the insertion rod 20 is inserted into the guide grooves on the upper and lower surfaces of the fixed frame 9, the mounting plate 8 and the fixed frame 9 can be fixed. At this time, the front cover 3 and the spray head 2 can be fixedly installed. At the same time, it is convenient for the user to disassemble the front cover 3, so as to facilitate the user to clean the interior of the front cover 3 and the spray head 2, effectively improving the overall practicality of the shower head.

[0036] Considering that after the front cover 3 and the spray head 2 are installed, it is necessary to improve the sealing between the front cover 3 and the spray head 2, a rubber sealing ring 22 is glued to the outside of the front cover 3. The setting of the rubber sealing ring 22 can effectively improve the sealing between the front cover 3 and the spray head 2, thereby avoiding water leakage during the use of the shower head.

[0037] To effectively install the filter element body 10, the fixing assembly includes a fixing plate 4 fixedly connected to the outside of the connecting pipe 1. A sliding rod 11 is fixedly connected inside the fixing plate 4. A movable plate 12 is located inside the fixing plate 4, with a guide groove for the sliding rod 11 to move. A retaining spring 13 is sleeved on the outside of the sliding rod 11, abutting between the movable plate 12 and the fixing plate 4. Connecting rods 14 are symmetrically arranged on the front surface of the movable plate 12, and a pull plate is fixedly connected to the other end of each connecting rod 14. Fixing rods 15 are symmetrically arranged on the rear surface of the movable plate 12. Guide grooves for the fixing rods 15 are provided on the contact surfaces of the fixing plate 4 and the connecting pipe 1. Guide grooves for the fixing rods 15 are also provided inside the two limiting frames 17 and the retaining block 16. When the filter element body 10 needs to be fixedly installed, simply pull the pull plate first. At this time, the pull plate will... The connecting rod 14 moves synchronously, and the connecting rod 14 then moves the moving plate 12 synchronously outside the slide rod 11. During the movement of the moving plate 12, it will compress the abutment spring 13. The moving plate 12 will also move the fixing rod 15 synchronously. At this time, the filter element body 10 is inserted into the inside of the connecting pipe 1. The filter element body 10 will move the abutment block 16 synchronously. When the abutment block 16 is inserted into the inside of the limiting frame 17, the pull plate is released. At this time, the abutment spring 13 returns to its original position and moves the moving plate 12 synchronously. The moving plate 12 then moves the fixing rod 15 synchronously. When the fixing rod 15 is inserted into the guide groove inside the limiting frame 17 and the abutment block 16, the limiting frame 17 and the abutment block 16 can be fixed. At this time, the filter element body 10 can be fixedly installed, so that the filter element body 10 can effectively filter water.

[0038] To prevent the shower head from slipping and falling during use, an anti-slip sleeve 5 is fitted over the connecting pipe 1. The anti-slip sleeve 5 has herringbone-shaped anti-slip grooves at equal intervals. The anti-slip sleeve 5 and the herringbone-shaped anti-slip grooves effectively increase the friction between the user's hand and the connecting pipe 1, thus preventing the shower head from slipping and falling, which would affect its normal operation.

[0039] In addition, in order to facilitate the user's fixed installation of the connecting pipe 1, the connecting pipe 1 is provided with an external thread 6. The external thread 6 makes it easy for the user to fix the shower head, thus facilitating the normal use of the shower head.
